Detailed description of embodiments

[0053] New household appliances such as vacuum cleaners, floor scrubbers and other household cleaning devices are increasingly appearing in people's lives. At present, a cleaning device can comprise a host and a floor brush structure. The host and the floor brush structure are hinged to each other so that the host can rotate relative to the floor brush structure between a lying state and an upright state. The floor brush structure has a cleaning member and the host has a clean water tank between which and the cleaning member there is a connecting water conduit that can be opened and closed. When the connecting water conduit is opened, water in the clean water tank can soak the cleaning member through the connecting water conduit, so that the cleaning member can be used to wet mop a floor, for example, to improve the cleanliness of the floor, for example. However, when the clean water tank is assembled to the host, the connecting water conduit needs to go around the host to a floor brush, which makes the assembly time-consuming and laborious, and makes a user spend a lot of efforts when using the cleaning device.

[0054] In order to solve the above problems, embodiments of the present application provide a floor brush assembly and a cleaning device, wherein a clean water tank is mounted on a floor brush base, and a recessed portion for limiting the position of the clean water tank and a snap-fit mechanism are designed on the floor brush base, so that the clean water tank can be limited in position and fixed through the recessed portion and the snap-fit mechanism, which makes the assembly and disassembly convenient and saves time and effort. In addition, by arranging the clean water tank on the floor brush base, the weight of the host of the cleaning device can be reduced, so that consumers can use the cleaning device more easily, thereby improving a user's utilization experience.

[0055] In order to make the above-mentioned objectives, features and advantages of embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part, not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present application.

Embodiment 1

[0056] Please refer to Figs. 1 to 8. An embodiment of the present application provides a floor brush assembly 100, which is applied to a cleaning device. The cleaning device can be a vacuum cleaner with a roller brush or an automatic cleaning robot used to clean, for example, a floor. The embodiment of the present application does not specifically limit the type of the cleaning device.

[0057] The cleaning device comprises a floor brush assembly 100, a host and a clean water tank 120. The host is connected to the floor brush assembly 100. The floor brush assembly 100 comprises, for example, a floor brush base 110 and a roller brush connected to the floor brush base 110. The clean water tank 120 is configured to store a cleaning liquid. For example, the cleaning liquid can be water or a liquid of mixed detergent and water. When the cleaning device cleans a floor, as the cleaning device moves in a forward direction, the roller brush can rotate relative to the floor, and the clean water tank 120 discharges the cleaning liquid which can be directed to the roller brush via a conduit and, by rotation of the roller brush, clean and mop the floor, thereby achieving the objective of cleaning the floor by the cleaning device.

[0058] In order to make it relatively easy for a user to use the cleaning device, in an embodiment of the present application, the clean water tank 120 can be arranged on the floor brush base 110, wherein the floor brush base 110 has a recessed portion 111, and at least part of the structure of the clean water tank 120 matches the contour of the recessed portion 111. By way of example, at least part of the structure of the clean water tank 120 matches the contour of the recessed portion 111. When the clean water tank 120 is placed on the floor brush base 110, at least part of the structure of the clean water tank 120 is located in the recessed portion 111, so that the recessed portion 111 can limit the position of the clean water tank 120 in at least one direction, such as a horizontal direction. The horizontal direction is, for example, a direction parallel to the floor being cleaned when the floor brush assembly 100 is normally placed on the floor. In addition, the clean water tank 120 has a first snap-fit structure which has a first snap-fit portion 121. The floor brush base 110 has a second snap-fit structure which has a second snap-fit portion 112 matching the first snap-fit portion 121. At least one of the first snap-fit portion 121 and the second snap-fit portion 112 can extend and retract relative to the other. When the clean water tank 120 is arranged on the floor brush base 110, the first snap-fit portion 121 snap fits with the second snap-fit portion 112, so that the clean water tank 120 is limited in position in at least one direction in a horizontal direction by the recessed portion 111, and then the clean water tank 120 and the floor brush base 110 are fixed relative to each other by snap-fit, so that the clean water tank 120 can be detachably mounted on the floor brush base 110, which makes it easy to assemble and disassemble and saves time and effort.

[0059] In one example, the outer contour of the clean water tank 120 is a rectangular structure, and the recessed portion 111 is a rectangular groove matching the outer contour of the clean water tank 120, a side wall of the groove being an opening structure. The clean water tank 120 can be placed in the recessed portion 111 through the opening structure of the groove, and limited in position in three directions in the horizontal direction by the walls of the groove. A second snap-fit portion 112 is provided at a position of the floor brush base 110 corresponding to the opening structure. A first snap-fit portion 121 is provided at a side of the clean water tank 120 facing the opening structure. Thus, when the clean water tank 120 is placed in the groove, the first snap-fit portion 121 and the second snap-fit portion 112 snap fit with each other, thereby limiting the position of the clean water tank 120 relative to the floor brush base 110 and fixing them.

[0060] In other embodiments, the recessed portion 111 is configured to limit the relative position of the clean water tank 120 and the floor brush base 110 in the horizontal direction. For example, the recessed portion 111 has a recessed shape that matches the outer contour of the clean water tank 120 (as shown in Fig. 2). When the clean water tank 120 is placed in the recessed portion 111, the recessed portion 111 can limit the position of the clean water tank 120 entirely in the horizontal direction. After the clean water tank 120 is placed in the recessed portion 111, the first snap-fit portion 121 and the second snap-fit portion 112 snap fit with each other. The snap fit between the first snap-fit portion 121 and the second snap-fit portion 112 limits the movement of the clean water tank 120 and the floor brush base 110 in the vertical direction, thereby realizing limiting and fixation of the clean water tank 120 in the horizontal and vertical directions. The vertical direction is, for example, a direction perpendicular to the floor being cleaned. Thus, the reliability of the fixation between the clean water tank 120 and the floor brush base 110 is improved, with the assembly and disassembly thereof being facilitated.

[0061] By way of example, the first snap-fit portion 121 can be at a number of one, two or more, so long as the movement of the clean water tank 120 relative to the floor brush base 110 in the vertical direction can be limited by the snap fit between the first snap-fit portion 121 and the second snap-fit portion 112 after the first snap-fit portion 121 snap fits with the second snap-fit portion 112. No limitation is made here.

[0062] The first snap-fit portion 121 can also be arranged at a position close to a side wall of the clean water tank 120, or on a bottom wall of the clean water tank 120 facing the floor brush base 110, and the second snap-fit portion 112 is arranged at a position corresponding to the first snap-fit portion 121, so long as when the clean water tank 120 is arranged on the floor brush base 110, the first snap-fit portion 121 can snap fit with the second snap-fit portion 112. No limitation is made here.

[0063] For example, in Figs. 3 to 8, there are two first snap-fit portions 121, which are arranged on opposite sides of the clean water tank 120. Correspondingly, second snap-fit portions 112 are arranged on the floor brush base 110 at positions corresponding to the first snap-fit portions 121 respectively. In this way, the clean water tank 120 is arranged on the floor brush base 110, with at least part of the clean water tank 120 located in the recessed portion 111, and the two first snap-fit portions 121 snapping fit with the second snap-fit portions 112 on the floor brush base 110, respectively. In this way, the reliability of the position-limiting and fixation between the clean water tank 120 and the floor brush base 110, and the stability of the clean water tank 120 on the floor brush base 110 can be improved.

[0064] In some embodiments, the first snap-fit portion 121 is, for example, one of a snap protrusion, a buckle, or a snap slot, and the second snap-fit portion 112 is, for example, one of a snap protrusion, a buckle, or a snap slot that matches the first snap-fit portion 121, as long as the first snap-fit portion 121 and the second snap-fit portion 112 snap fit with each other. No limitation is made here.

[0065] It can be seen that in the embodiments of the present application, the clean water tank 120 is mounted on the floor brush base 110, and the floor brush base 110 has a recessed portion 111 that matches at least part of the structure of the clean water tank 120. When the clean water tank 120 is arranged on the floor brush base 110, the recessed portion 111 limits the position of the clean water tank 120. In addition, the clean water tank 120 has a first snap-fit portion 121, and the floor brush base 110 has a second snap-fit portion 112. At least one of the first snap-fit portion 121 and the second snap-fit portion 112 extends and retracts relative to the other, so that the clean water tank 120 snap fits with the second snap-fit portion 112 on the floor brush base 110 through the first snap-fit portion 121, so that the clean water tank 120 is fixed to the floor brush base 110. Thus, the assembly and disassembly are facilitated, and time and effort are saved. In addition, by arranging the clean water tank 120 on the floor brush base 110, the weight of the host of the cleaning device can be reduced, so that consumers can use the cleaning device easily, thereby improving a user's utilization experience.

[0066] In some embodiments, still in reference to Fig. 1, when assembling and disassembling the clean water tank 120, in order to make it easy for a user to carry the clean water tank 120, the clean water tank 120 can be provided on opposite sides with gripping portions 129 for the user to hold. The user can carry the clean water tank 120 by holding the gripping portions 129. By way of example, in reference to Fig. 1, the gripping portions 129 can be gripping slots provided on opposite sides of the clean water tank 120. The user's fingers are hooked on the wall of the gripping slots to carry the clean water tank 120, thereby enhancing the user's utilization experience.

[0067] In some embodiments, in reference to Figs. 3 to 8, the clean water tank 120 has two first snap-fit structures, which are located on opposite sides of the clean water tank 120. Second snap-fit structures are arranged at positions on the floor brush base 110 corresponding to the two first snap-fit structures. In the embodiments of the present application, the first snap-fit structures are provided on opposite sides of the clean water tank 120, each first snap-fit structure has a first snap-fit portion 121, and correspondingly, the second snap-fit structures are arranged at positions on the floor brush base 110 corresponding to the first snap-fit structures and have second snap-fit portions 112 matching the first snap-fit portions 121. In this way, the reliability of the fixation between the clean water tank 120 and the floor brush base 110 can be improved.

[0068] In some embodiments, in reference to Figs. 3, 4, and 6 to 8, the first snap-fit structure comprises a first snap-fit member 122 and a first elastic member 123. The first snap-fit member 122 is movably arranged in the clean water tank 120. The first elastic member 123 is connected between the clean water tank 120 and the first snap-fit member 122. An end of the first snap-fit member 122 away from the first elastic member 123 has a first snap-fit portion 121. The first elastic member 123 is configured to drive the first snap-fit member 122 to move toward the second snap-fit portion 112 through its own elastic force, so that the first snap-fit portion 121 and the second snap-fit portion 112 are connected in a snap-fit manner; or the first snap-fit portion 122 moves in a direction away from the second snap-fit portion 112 under the action of an external force, so that the first snap-fit portion 121 and the second snap-fit portion 112 disengage from snap-fit. It can be understood that with the first elastic member 123 capable of driving the first snap-fit portion 122 to move toward the second snap-fit portion 112 through its own elastic force, reliability of the snap-fit between the first snap-fit portion 121 and the second snap-fit portion 112 can be improved, and the problem of easy disengagement of snap-fit between the first snap-fit portion 121 and the second snap-fit portion 112 without the action of an external force can be avoided.

[0069] By way of example, the first snap-fit portion 121 is, for example, a snap protrusion, and the second snap-fit portion 112 is, for example, a snap slot matching the snap protrusion. When the clean water tank 120 is arranged on the floor brush base 110, the first snap-fit portion 121 snap fits with the second snap-fit portion 112. At the same time, the elastic force of the first elastic member 123 itself applies a pushing force toward the second snap-fit portion 112 to the first snap-fit member 122, thereby improving the reliability of the snap-fit between the first snap-fit portion 121 and the second snap-fit portion 112. When the first snap-fit portion 121 and the second snap-fit portion 112 need to disengage from snap-fit, a user can pull the clean water tank 120 to a side away from the floor brush base 110 by hooking the gripping portions 129. In this way, the first snap-fit portion 121 and the second snap-fit portion 112 push against each other under the action of the pulling force. Thus, the first snap-fit portion 121 moves to a side away from the second snap-fit portion 112 under the action of a reverse pushing force of the second snap-fit portion 112, so that the first snap-fit portion 122 gradually compresses the first elastic member 123, putting the first elastic member 123 in a compressed state until the first snap-fit portion 121 and the second snap-fit portion 112 disengage from snap-fit. At this time, the first elastic member 123 drives the first snap-fit member 122 to move to a side away from the first elastic member 123 through its own elastic force, so that the first snap-fit portion 121 automatically resets, without the need to additionally provide a reset mechanism and operation. The structure is simple, operation is convenient, and cost is low.

[0070] In some embodiments, in reference to Figs. 6 and 7, the clean water tank 120 is provided with an accommodating chamber 113 at a side facing the floor brush base 110. The clean water tank 120 is provided in a side wall corresponding to the accommodating chamber 113 with a notch 114 in communication with the accommodating chamber 113. The notch 114 allows the first snap-fit portion 121 to pass through. The first snap-fit member 122 is slidably arranged in the accommodating chamber 113, and the first snap-fit portion 121 passes through the notch 114. An end of the first elastic member 123 is connected to an end of the first snap-fit member 122 away from the first snap-fit portion 121. The other end of the first elastic member 123 is connected to a wall of the accommodating chamber 113. The first elastic member 123 can drive the first snap-fit member 122 to move by its own elastic force, so that the first snap-fit portion 121 snap fits with the second snap-fit portion 112 on the floor brush base 110 through the notch 114. In this way, the accommodating chamber 113 can accommodate the first snap-fit member 122 and the first elastic member 123 to prevent the first snap-fit member 122 and the first elastic member from falling off. Also, external dimensions of the floor brush assembly 100 can be reduced, thereby improving the structural compactness of the cleaning device.

[0071] In order to limit the position of, and fix, the first elastic member 123, in the embodiment of the present application, in reference to Figs. 6 and 7, the accommodating chamber 113 is provided on a wall corresponding to the first elastic member 123 with a first limiting portion 115. An end of the first snap-fit member 122 away from the first snap-fit portion 121 has a second limiting portion 1221. Two ends of the first elastic member 123 are respectively connected to the first limiting portion 115 and the second limiting portion 1221. The first limiting portion 115 and the second limiting portion 1221 are configured to limit the movement of the first elastic member 123 in a direction perpendicular to the movement of the first snap-fit member 122. In this way, the first limiting portion 115 and the second limiting portion 1221 limit the movement of the first elastic member 123 in a direction perpendicular to the movement of the first snap-fit member 122, so that the first elastic member 123 only retains a degree of freedom in the direction of its own elastic force. Thus, the reliability of the first elastic member 123 driving the first snap-fit member 122 to move can be improved.

[0072] By way of example, the first limiting portion 115 and the second limiting portion 1221 can be at least one of a limiting slot or a limiting protrusion. For example, the first limiting portion 115 is one of a limiting slot and a limiting protrusion, and the second limiting portion 1221 is one of a limiting protrusion and a limiting slot. Two ends of the first elastic member 123 are respectively connected to the first limiting portion 115 and the second limiting portion 1221, so that the movement of the first elastic member 123 in a direction perpendicular to the direction of the elastic force of the first elastic member 123 is limited through the first limiting portion 115 and the second limiting portion 1221. Thus, the position accuracy of the first elastic member 123 can be improved, thereby providing the first snap-fit member 122 with movement reliability and accuracy.

[0073] For example, in Figs. 6 and 7, the first limiting portion 115 is a limiting slot, the second limiting portion 1221 is a limiting protrusion, and the first elastic member 123 is a spring. An end of the spring is located in the limiting slot and abuts against the bottom wall of the limiting slot, while the side walls of the limiting slot limit the position of the spring in the circumferential direction. The other end of the spring is sleeved on the limiting protrusion. In this way, movement of the spring in the circumferential direction can be limited. The structure is simple, easy to process, and low in cost.

[0074] In some embodiments, the first snap-fit member 122 is provided with an accommodating slot at an end away from the first snap-fit portion 121 and a limiting protrusion is provided in the accommodating slot. In this way, the wall of the accommodating slot can also limit the position of the first elastic member 123 connected to the second limiting portion 1221 in the circumferential direction, so as to further improve the path accuracy of the first elastic member 123 during elastic movement.

[0075] In order to further improve the reliability of the connection between the limiting protrusion and the spring, in the embodiment of the present application, the limiting protrusion can comprise a first protrusion 1222 and a second protrusion 1223, which are arranged crosswise. For example, the first protrusion 1222 and the second protrusion 1223 are arranged to be perpendicular to each other (as shown in Fig. 7). In this way, the spring is sleeved on an end of the limiting protrusion formed by the cross-arrangement of the first protrusion 1222 and the second protrusion 1223. The edges of the first protrusion 1222 and the second protrusion 1223 can limit circumferential movement of the spring. By forming the limiting protrusion as the cross-arranged first protrusion 1222 and second protrusion 1223, the reliability of position-limiting can be improved while saving materials and reducing costs.

[0076] In addition, two limiting ribs extending in a vertical direction are provided on the wall of the accommodating chamber 113 away from the first snap-fit member 122 (as shown in Fig. 6). In this way, the two limiting ribs and the bottom wall and the top wall of the accommodating chamber 113 jointly enclose a limiting slot. An end of the spring is located in the limiting slot. In this way, the limiting rib can be integrally formed with the accommodating chamber 113 through an integral molding process. Thus, the difficulty of processing the limiting slot can be reduced.

[0077] In some embodiments, a slide rail 116 is provided in the accommodating chamber 113. The first snap-fit member 122 has a slider matching the slide rail 116. The first snap-fit member 122 extends and retracts along the slide rail 116 relative to the second snap-fit portion 112 under the action of a force. It can be understood that the slide rail 116 extends in the sliding direction of the first snap-fit member 122, so that the first snap-fit member 122 slides along the slide rail 116 when sliding, so as to improve the path accuracy of the first snap-fit member 122 when moving in the accommodating chamber 113, thereby improving the stability of the first snap-fit portion 121 and the second snap-fit portion 112 when snap fitted or disengaged from snap-fit.

[0078] By way of example, in Figs. 6 and 7, two guide protrusions are arranged in a spaced apart manner on the wall of the accommodating chamber 113. The two guide protrusions together form the slide rail 116. By way of example, the outer contour of the first snap-fit member 122 is formed as a slider structure matching the slide rail 116. Thus, the first snap-fit member 122 can move along the slide rail 116 in the accommodating chamber 113 under a force, so that the first snap-fit portion 121 extends towards or retracts from the second snap-fit portion 112 to cause the first snap-fit portion 121 to snap fit or disengage from snap-fit with the second snap-fit portion 112.

[0079] In some embodiments, the first snap-fit structure further comprises a limiting cover 124. Aside of the accommodating chamber 113 facing the floor brush base 110 is an opening structure. The limiting cover 124 detachably covers the opening structure. In this way, assembly and disassembly of the first snap-fit member 122 and the first elastic member 123 can be facilitated, and at the same time, the first snap-fit member 122 and the first elastic member 123 in the accommodating chamber 113 can also be limited in position in a vertical direction by the limiting cover 124 to prevent the first snap-fit member 122 and the second elastic member 132 from falling off.

[0080] In some embodiments, the limiting cover 124 can be detachably connected to the clean water tank 120 through a threaded connector. For example, in Fig. 7, the limiting cover 124 is provided with two through holes arranged in a spaced apart manner. The accommodating chamber 113 is provided with two threaded pins. The threaded pins are provided with threaded holes coaxial with the through holes. When the limiting cover 124 covers the opening structure of the accommodating chamber 113, the threaded connector can pass through the through holes to be threadedly connected with the threaded holes, so as to fix the limiting cover 124 on the clean water tank 120 (as shown in Fig. 5), so that at least part of the first snap-fit portion 121 is exposed outside the clean water tank 120 and can extend and retract to facilitate snap-fit or disengagement from snap-fit with the second snap-fit portion 112.

[0081] In some embodiments, in reference to Fig. 2, a second snap-fit portion 112 is provided at a position corresponding to the first snap-fit portion 121 on the side wall of the recessed portion 111. The first snap-fit portion 121 extends and retracts relative to the second snap-fit portion 112 so that the first snap-fit portion 121 snap fits or disengages from snap-fit with the second snap-fit portion 112. In this way, the recessed portion 111 can limit the position of the clean water tank 120 in the horizontal direction, and the first snap-fit portion 121 and the second snap-fit portion 112 can limit the position of the clean water tank 120 in the vertical direction, so as to improve the reliability of the position limitation and fixation between the clean water tank 120 and the floor brush base 110.

[0082] By way of example, as shown in Figs. 2 to 4, the first snap-fit portion 121 is a snap protrusion, and the second snap-fit portion 112 is a snap slot matching the snap protrusion. The snap protrusion can extend and retract relative to the snap slot. For example, when the clean water tank 120 is arranged on the floor brush base 110, the snap protrusion snap fits in the snap slot. The snap-fit approach is simple, easy to implement, and low in cost.

[0083] In order to prevent jamming when the snap protrusion and the snap slot are snap fitted, in the embodiment of the present application, as shown in Fig. 4, a guide slope 1211 is provided at an end of the snap protrusion facing the snap slot. In this way, when the snap protrusion moves toward the snap slot, the guide slope 1211 can guide the movement path of the snap protrusion so as to help it snap fit into the snap slot. This can prevent jamming of the snap-fit due to an error in positioning the snap protrusion and the snap slot, thereby improving the reliability of the snap-fit between the snap protrusion and the snap slot.

[0084] In addition, in order to improve the accuracy for positioning the clean water tank 120 on the floor brush base 110, in reference to Figs. 2 and 6, in the embodiment of the present application, a first guide portion 125 is provided on a side wall of the clean water tank 120, and a second guide portion 117 is provided on an inner wall of the recessed portion 111 at a position corresponding to the first guide portion 125. The second guide portion 117 matches the first guide portion 125. When the clean water tank 120 is arranged on the floor brush base 110, the first guide portion 125 moves along the second guide portion 117, thereby improving the positioning accuracy of the clean water tank 120 after being mounted on the floor brush base 110.

[0085] By way of example, in Figs. 2 and 6, the first guide portion 125 is a guide slot, and the second guide portion 117 is a guide protrusion matching the guide slot. When the clean water tank 120 is arranged on the floor brush base 110, the first guide portion 125 and the second guide portion 117 are aligned, and the first guide portion 125 moves along the second guide portion 117. After the clean water tank 120 is arranged on the floor brush base 110, for example, the guide protrusion is located in the guide slot, so that the clean water tank 120 is first positioned by the guide protrusion and the guide slot, thereby improving the accuracy of positioning between the first snap-fit portion 121 and the second snap-fit portion 112, preventing the problem that the first snap-fit portion 121 and the second snap-fit portion 112 cannot snap fit or disengage from snap-fit due to inaccurate positioning. In addition, the structure is simple, easy to process, and low in cost.

[0086] In addition, there can be two first guide portions 125 that can be symmetrically arranged on side walls on opposite sides of the clean water tank 120. Correspondingly, second guide portions 117 are arranged on the floor brush base 110 at positions corresponding to the two first guide portions 125, so as to further improve the accuracy of positioning between the clean water tank 120 and the floor brush base 110 through the two first guide portions 125 and the two second guide portions 117.

Embodiment 2

[0087] Only differences of the present embodiment from the first embodiment will be described, without repeating the common points.

[0088] In reference to Figs. 9 to 18, in the embodiment of the present application, the clean water tank 120 is also arranged on the floor brush base 110, and the floor brush base 110 is provided with a recessed portion 111 that matches at least a part of the clean water tank 120. When the clean water tank 120 is arranged on the floor brush base 110, at least a part of the clean water tank 120 is located in the recessed portion 111, so that the clean water tank 120 is limited in position in, for example, a horizontal direction by the recessed portion 111. In addition, a first snap-fit structure is provided on the clean water tank 120, and a second snap-fit structure is provided on the floor brush base 110. The clean water tank 120 and the floor brush base 110 can snap fit with each other through the first snap-fit structure and the second snap-fit structure, so as to limit the position of the clean water tank 120 in, for example, a vertical direction, so that the clean water tank 120 is arranged on the floor brush base 110 with its position limited and fixed, and the clean water tank 120 is detachable.

[0089] In some embodiments, the clean water tank 120 has a recessed chamber 126 on a side facing the floor brush base 110. The first elastic member 123 and the first snap-fit member 122 are located in the recessed chamber 126. The first elastic member 123 is connected between the first snap-fit member 122 and a side wall of the recessed chamber 126. The first snap-fit portion 121 is arranged at an end of the first snap-fit member 122 away from the first elastic member 123. A snap-fit space 1261 is formed between the first snap-fit portion 121 and the side wall of the recessed chamber 126 corresponding to the first snap-fit portion 121. A snap-fit opening in communication with the snap-fit space 1261 is provided on the side of the clean water tank 120 facing the floor brush base 110. The second snap-fit structure comprises a second snap-fit member 118 arranged on the side of the floor brush base 110 facing the clean water tank 120. The second snap-fit member 118 has a second snap-fit portion 112 at an end facing the clean water tank 120. At least a part of the second snap-fit member 118 is inserted into the snap-fit space 1261 through the snap-fit opening, so that the second snap-fit portion 112 snap fits with the first snap-fit portion 121.

[0090] In the embodiment of the present application, when the clean water tank 120 is arranged on the floor brush base 110, the second snap-fit member 118 is inserted into the snap-fit space 1261 through the snap-fit opening, so that the second snap-fit portion 112 on the second snap-fit member 118 snap fits with the first snap-fit portion 121 (as shown in Fig. 12). In this way, while fixing the clean water tank 120, the first snap-fit structure and the second snap-fit structure can be received between the clean water tank 120 and the floor brush base 110, so that invisible snap-fit is formed between the clean water tank 120 and the floor brush base 110. In this way, while limiting the position of, and fixing, the clean water tank 120, the appearance aesthetics of the cleaning device can be improved, and the structure of the cleaning device can be made more compact, so that the cleaning device can be further miniaturized.

[0091] In some embodiments, in reference to Figs. 12 and 18, the recessed chamber 126 is arranged near the edge of the clean water tank 120. An end of the first elastic member 123 abuts against a wall of the recessed chamber 126 near the outer side of the clean water tank 120.The other end of the first elastic member 123 is connected to the first snap-fit member 122. The first snap-fit portion 121 is arranged at an end of the first snap-fit member 122 away from the first elastic member 123, and faces the inside of the clean water tank 120. The second snap-fit portion 112 is inserted into the snap-fit space 1261 of the clean water tank 120 and faces the first snap-fit portion 121. The structure of the second snap-fit portion 112 matches the structure of the first snap-fit portion 121. For example, when the first snap-fit portion 121 is a snap protrusion, the second snap-fit portion 112 is a snap buckle extending toward a side of the first snap-fit portion 121, so that the first snap-fit portion 121 can snap fit with the second snap-fit portion 112. Alternatively, the first snap-fit portion 121 is a snap buckle, and the second snap-fit portion 112 is a snap protrusion. Still alternatively, one of the first snap-fit portion 121 and the second snap-fit portion 112 comprises a snap slot, and the other of the first snap-fit portion 121 and the second snap-fit portion 112 comprises a snap protrusion or a snap buckle, as long as the first snap-fit portion 121 and the second snap-fit portion 112 can snap fit with each other. No limitation is made here.

[0092] In other embodiments, the first elastic member 123, the first snap-fit member 122 and the snap-fit space 1261, etc. are all rotated by 180 degrees in the horizontal direction. That is, the snap-fit space 1261 is located at an end close to the outer side of the clean water tank 120, and the first elastic member 123 is located on a side close to the inside of the clean water tank 120 relative to the first snap-fit member 122. Correspondingly, the orientation and structure of the second snap-fit member 118 and the second snap-fit portion 112 thereof match the first snap-fit portion 121, as long as the clean water tank 120 and the floor brush base 110 can snap fit through the first snap-fit portion 121 and the second snap-fit portion 112 so as to limit the position of, and fix, the clean water tank 120. No limitation is made here.

[0093] By way of example, still in reference to Figs. 12 and 18, the first elastic member 123 can be a spring, and a limiting protrusion or a limiting slot is arranged on a wall of the recessed chamber 126 corresponding to the first elastic member 123. For example, in Fig. 12, a limiting protrusion is provided on the wall of the recessed chamber 126, and an end of the spring is sleeved on the limiting protrusion so as to limit the position of the spring in the circumferential direction through the limiting protrusion. Correspondingly, an end of the first snap-fit member 122 facing the spring has a limiting slot and a limiting protrusion. For example, in Fig. 12, an end of the first snap-fit member 122 facing the spring has a limiting slot, and an end of the spring is located in the limiting slot so as to limit the position of the spring in the circumferential direction. In this way, the first snap-fit member 122 can move toward the spring under the action of an external force to release the snap-fit between the first snap-fit portion 121 and the second snap-fit portion 112. At this time, the spring is in a compressed state. When the external force on the first snap-fit member 122 is removed, the spring can drive the first snap-fit portion 121 to move toward the second snap-fit portion 112 through its own elastic force, so that the first snap-fit portion 121 is automatically reset. The reset approach is simple and low in cost.

[0094] In some embodiments, in reference to Figs. 14 and 17, there can also be two first snap-fit structures, which are symmetrically arranged in the clean water tank 120. Second snap-fit structures are arranged at positions on the floor brush base 110 corresponding to the first snap-fit structures respectively. In this way, the clean water tank 120 and the floor brush base 110 are limited in position and fixed jointly by the two first snap-fit structures and the two second snap-fit structures, which can improve the reliability of limiting and fixation of the clean water tank 120.

[0095] In specific implementation, when the clean water tank 120 needs to be mounted on the floor brush base 110, the clean water tank 120 can be placed on the floor brush base 110 with the second snap-fit member 118 on the floor brush base 110 inserted into the snap-fit space 1261 through the snap-fit opening, and a pressing force is applied to the clean water tank 120, so that the first snap-fit portion 121 (e.g., a snap protrusion) on the first snap-fit member 122 snap fits with the second snap-fit portion 112 (e.g., a snap buckle) on the second snap-fit member 118, thereby fixing the clean water tank 120 on the floor brush base 110. When the clean water tank 120 needs to be disassembled from the floor brush base 110, for example, a lifting force can be applied to the clean water tank 120 to move the clean water tank 120 upward. At this time, the first snap-fit portion 121 and the second snap-fit portion 112 push each other. Since the first snap-fit portion 121 has a degree of freedom to move toward an end away from the second snap-fit portion 112, under the action of a reverse pushing force of the second snap-fit portion 112, the first snap-fit portion 121 moves toward the end away from the second snap-fit portion 112 until the first snap-fit portion 121 and the second snap-fit portion 112 disengage from snap-fit, so as to realize the disassembly of the clean water tank 120 from the floor brush base 110.

[0096] In some embodiments, in reference to Fig. 15, the clean water tank 120 comprises an upper housing 127 and a lower housing 128, which are connected together to jointly enclose a clean water chamber. A groove is provided on a side of the upper housing 127 facing the lower housing 128. The lower housing 128 covers part of the opening of the groove, so that the walls of the groove and the lower housing 128 jointly enclose the recessed chamber 126. The opening of the groove not covered by the lower housing 128 forms the snap-fit opening, so as to facilitate the mounting of the first snap-fit member 122 and the first elastic member 123 in the recessed chamber 126, and the first snap-fit member 122 and the first elastic member 123 are limited in position by the lower housing 128 to prevent the first snap-fit member 122 and the first elastic member 123 from falling off.

[0097] The upper housing 127 and the lower housing 128 can be detachably connected together by a threaded connector, a magnetic member, etc., or can be fixedly connected by welding, gluing, etc.. No limitation is made here.

[0098] In the embodiment of the present application, gripping portions 129 are also provided on opposite sides of the clean water tank 120. When the clean water tank 120 needs to be arranged on the floor brush base 110 or disassembled from the floor brush base 110, a user can carry the clean water tank 120 by hooking the gripping portions 129 to improve the comfort of the user when carrying it. By way of example, the gripping portions 129 are arranged on opposite sides of the upper housing 127 of the clean water tank 120. The gripping portions 129 can be formed into an integral structure with the upper housing 127 through an integral molding process such as injection molding or casting. Thus, the process can be reduced and cost can be reduced.

[0099] The position where the gripping portions 129 come into contact with a user's fingers can match the shape of human fingers during gripping, so as to further improve comfort during gripping and enhance the user's utilization experience.

[0100] Of course, the gripping portions 129 can also be a gripping handle, as long as they help the user move the clean water tank 120. No limitation is made here.

Embdiment 3

[0101] The solution of the embodiment of the present application can be further improved based on embodiment 1 or embodiment 2. The further improvements of the floor brush assembly 100 will be described in detail below based on the embodiment.

[0102] In reference to Figs. 19 to 23, the floor brush assembly 100 provided by the embodiment of the present application further comprises an unlocking mechanism 130 movably arranged on the clean water tank 120. The unlocking mechanism 130 is configured to drive the first snap-fit portion 121 to move in a direction away from the second snap-fit portion 112, so as to disengage from snap-fit between the first snap-fit portion 121 and the second snap-fit portion 112, thereby improving the convenience of assembly and disassembly between the clean water tank 120 and the floor brush base 110.

[0103] In some embodiments, the unlocking mechanism 130 comprises a pressing member 131 and a second elastic member 132. The second elastic member 132 is connected between the pressing member 131 and the first snap-fit portion 121 in the vertical direction. The pressing member 131 moves toward the first snap-fit portion 121 in the vertical direction under a pressing force. When the pressing member 131 abuts against an end of the first snap-fit portion 121 close to the second snap-fit portion 112, the pressing force continues to be applied to the pressing member 131, so that the first snap-fit portion 121 moves to a side away from the second snap-fit portion 112 under the pushing force of the pressing member 131, so as to disengage the first snap-fit portion 121 and the second snap-fit portion 112 from snap-fit, thereby facilitating the disassembly of the clean water tank 120 from the floor brush base 110, which saves time and effort. Such an unlocking approach is simple, easy to implement, and low in cost. The second elastic member 132 is configured to drive the pressing member 131 to move in the vertical direction away from the first snap-fit portion 121 through its own elastic force. That is, when the pressing force applied to the pressing member 131 is cancelled, the second elastic member 132 drives the pressing member 131 to move in the direction away from the first snap-fit portion 121 through its own elastic force, so that the pressing member 131 automatically resets. Such a reset approach is simple.

[0104] In some embodiments, the first snap-fit portion 121 has a guide slope 1211 on a side facing the pressing member 131, and an end of the pressing member 131 facing the first snap-fit portion 121 has a push slope 1311 matching the guide slope 1211. The pressing member 131 moves toward the first snap-fit portion 121 under a pressing force. The push slope 1311 is configured to move along the guide slope 1211 so that the first snap-fit portion 121 moves away from the second snap-fit portion 112. In this way, to drive the first snap-fit portion 121 to move away from the second snap-fit portion 112, the pressing force applied to the pressing part 131 only needs to overcome the elastic force of the second elastic member 132, so that the pressing member 131 moves toward the first snap-fit portion 121, causing the push force transmitted by the pressing member 131 to the first snap-fit portion 121 to be able to overcome the elastic force of the first elastic member 123, which saves time and effort and improves a user's utilization experience.

[0105] By way of example, as shown in Figs. 20 and 21, at this time, the pressing member 131 is in a free state, that is, no pressing force is applied to the pressing member 131. The first elastic member 123 and the second elastic member 132 are both in a free state. When a pressing force is applied to the pressing member 131 to move toward the first snap-fit portion 121, the pressing force overcomes the elastic force of the second elastic member 132 to move toward the first snap-fit portion 121. At this time, the second elastic member 132 is in a gradually compressed state. When the push slope 1311 on the pressing member 131 abuts against the guide slope 1211 on the first snap-fit portion 121, under the action of the pressing force, the push slope 1311 moves along the guide slope 1211 to drive the first snap-fit portion to move in a direction away from the second snap-fit portion 112. At this time, the first elastic member 123 is in a gradually compressed state until the first snap-fit portion 121 and the second snap-fit portion 112 disengage from snap-fit, as shown in Figs. 22 and 23.

[0106] When the external force pressing the pressing member 131 is cancelled, the first elastic member 123 drives the first snap-fit portion 121 to move toward the second snap-fit portion 112 by its own elastic force, so that the first snap-fit portion 121 is reset. At the same time, the second elastic member 132 drives the pressing member 131 to move away from the first snap-fit portion 121 by its own elastic force, so that the pressing member 131 is reset.

[0107] The pressing member 131 can be a pressing keycap, the outer surface of which can match the appearance of the clean water tank 120 to improve its aesthetic.

[0108] The first elastic member 123 and the second elastic member 132 can both be compression springs or tension springs of, for example, cylindrical structures. No specific limitation is made.

[0109] In addition, the number of unlocking mechanisms 130 can be consistent with the number of first snap-fit portions 121. When the number of unlocking mechanisms 130 is greater than one, the unlocking mechanisms 130 can be independently arranged. Alternatively, the pressing members 131 of different unlocking mechanisms 130 can be formed into an integral structure. In this way, when unlocking is required, only the pressing member 131 of the integral structure needs to be pressed to simultaneously unlock two or more snap-fit mechanisms. Specific adaptive design can be carried out according to actual needs, which is not limited here.
