DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The following clearly and completely describes the technical solution in the embodiments of the present disclosure with reference to the embodiments of the present disclosure. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. Based on the embodiment in the present disclosure, all other embodiments acquired by the person skilled in the art under the premise of without creative efforts belong to the scope of the present disclosure.
[0023] The present disclosure aims to provide a water surface cleaning device so as to solve the problems in the prior art. By means of the cooperation between the limiting rib and the limiting surface and the clamping of the buckle, the rotational restriction of the filter basket and the translational restriction in the in-and-out direction can be realized, so that the filter basket can be confined in the main body to realize stable installation. On this basis, the cover is hinged to the filter basket so that the cover is taken out together with the filter basket, thus preventing garbage in the filter basket from being scattered during cleaning the filter basket, so as to avoid the environmental pollution.
[0024] To make the foregoing objective, features and advantages of the present disclosure clearer and more comprehensible, the present disclosure is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] As shown in FIG. 1 to FIG. 16, the present disclosure provides a water surface cleaning device. The water surface cleaning device includes a main body 1, a cover 2 and a filter basket 3, wherein the main body 1 is a body of the water surface cleaning device, and includes a shell and various components installed on the shell, such as a power supply structure, a control structure, a driving structure. The main body 1 is formed with an opening for the filter basket 3 to get into and out of the main body 1. The filter basket 3 is placed into the main body 1 through the opening to realize installation of the filter basket 3 to the main body 1. The main body 1 drives the filter basket 3 to work to collect garbage such as floating objects on the water surface, the filter basket 3 is removed through the opening, so that the garbage within the filter basket 3 can be treated, and the filter basket 3 is cleaned. As shown in FIG. 7, a buckle 11 is arranged on one side of the opening. The buckle 11 can be of an overturning clamping structure, of which the clamping force is provided by a snap spring, the buckle 11 can be opened once the clamping force of the snap spring is overcame. As shown in FIG. 9, two sides of the filter basket 3 are respectively provided with a hinge part 36 and a clamping part 37. The hinge part 36 is hinged to one side of the cover 2. For example, a shaft hole 32 is formed in the hinge part 36, the cover 2 is provided with a rotating shaft 22 (as shown in FIG. 8), and the rotating shaft 22 is installed in the shaft hole 32 to realize rotational connection of the hinge part 36 and the cover 2. The other side of the cover 2 can be provided with a clamping groove 23. The clamping groove 23 can be clamped to the buckle 11, that is, the buckle 11 can be clamped within the clamping groove 23. It should be noted that the clamping part 37 of the filter basket 3 is located below the cover 2, and the other side of the cover 2 presses against the clamping part 37 when the buckle 11 is clamped within the clamping groove 23 ,as shown in FIG. 2, that is, after the cover 2 is clamped with the buckle 11, the filter basket 3 is simultaneously clamped.
[0026] As shown in FIG. 9, one side of the filter basket 3 where the hinge part 36 located is provided with a limiting rib 31. One or more limiting ribs 31 can be arranged. Preferably, two limiting ribs distributed on both sides of the hinge part 36 are arranged. As shown in FIG. 7, a limiting surface 16 is arranged at the position on the inner side of the opening of the main body 1 corresponding to the limiting rib 31. The limiting rib 31 and the limiting surface 16 extend in the in-and-out direction of the filter basket 3. After the filter basket 3 is installed, the limiting rib 31 is in contact with the limiting surface 16. The limiting surface 16 can only slide relative to the limiting rib 31, and the limiting rib 31 can be prevented from rotating about the clamping part 37 by means of the limiting surface 16. Specifically, in the state that the clamping part 37 is clamped, the clamping part 37 is equivalent to the rotation center, and the filter basket 3 can rotate about the clamping part 37 without the limiting rib 31 and the limiting surface 16 are arranged.
[0027] According to the water surface cleaning device, by means of the cooperation between the limiting rib 31 and the limiting surface 16, the rotation of the filter basket 3 about the clamping part 37 can be restricted, but the translation in the in-and-out direction of the filter basket 3 is allowed. The translation in the in-and-out direction of the filter basket 3 is restricted under the clamping of the buckle 11, and the rotation of the filter basket 3 about the clamping part 37 cannot be restricted. Thus, the filter basket 3 can be stably installed within the main body 1 by means of the restriction of the rotation and the translation restriction in the in-and-out direction of the filter basket 3 on the filter basket 3. When the filter basket 3 is disassembled, the filter basket 3 can be conveniently taken out only by releasing the clamping of the buckle 11, so that the installation and disassembly of the filter basket are more convenient. Furthermore, on this basis, as the cover 2 is hinged to the filter basket 3, the cover 2 is taken out together with the filter basket 3, and the filter basket 3 is covered by the cover 2, so that garbage in the filter basket 3 can be prevented from being scattered during cleaning the filter basket 3, and environmental pollution can be avoided.
[0028] As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 8 and FIG. 9, the cover 2 is provided with a hollow-out handle 21, and one side of the filter basket 3 where the clamping part 37 is located is provided a boss 33 which is configured for being held and extends towards the handle 21. The cover 2 is located above the boss 33, after a hand is put into the handle 21, the boss 33 can be dragged to taken out the filter basket 3 and the cover 2 together after the clamping of the buckle 11 to the cover 2 is released.
[0029] As shown in FIG. 7 and FIG. 8, a supporting projection 17 can be arranged on the inner side of the opening in the main body 1. The supporting projection 17 extends circumferentially along the inner-diameter side of the opening and can be configured for supporting an edge 24 of the cover 2. The edge 24 away from the handle 21 can cause interference between the cover 2 and the main body 1 when the cover 2 is turned over, so that the cover 2 cannot be completely opened, and can be opened only at a certain angle. Furthermore, the cover 2 can be completely opened only after the filter basket 3 is taken out together with the cover 2.
[0030] As shown in FIG. 3, FIG. 4 and FIG. 6, the main body 1 includes propellers 5, a power supply, a controller and the like. The propellers 5, the power supply and the controller are located on the same side of the main body 1 where the center of gravity of the whole water surface cleaning device is located and which is far away from the handle 21, that is, the side far away from the handle 21 is the center-of-gravity side, and the side where the handle 21 is located is the non-center-of-gravity side. In addition, the inlet of the filter basket 3 is located on the same side as the clamping part 37, that is, on the non-center-of-gravity side. When the water surface cleaning device is lifted via the handle 21, the center-of-gravity side naturally hangs downwards, while the inlet located on the non-center-of-gravity side naturally faces upwards. With this arrangement, when the water surface cleaning device is lifted, the inlet of the filter basket 3 is avoided from facing downwards so that the garbage in the filter basket 3 can be prevented from falling, thus the garbage can be effectively prevented from falling and polluting the surrounding environment during transfer of the water surface cleaning device.
[0031] As shown in FIG. 1, FIG. 4, FIG. 5 and FIG. 10, the inlet of the filter basket 3 is provided with a rolling brush 4. The rolling brush 4 is connected to a first motor 44. The first motor 44 can be connected to the rolling brush 4 via the transmission gear 45, so as to drive the rolling brush 4 to rotate, so that the garbage on the water surface is sucked into the filter basket 3. A flexible barrier strip 35 is arranged on one side, parallel to the rolling brush 4 of the inlet. Generally, the flexible barrier strip 35 is located on the lower side of the inlet. The rotation direction, at the flexible barrier strip 35, of the rolling brush 4 faces the filter basket 3. When the garbage is sucked, the flexible barrier strip 35 can be deformed toward the filter basket 3 under the driving of the rolling brush 4, so that larger garbage can be sucked. However, after the garbage is sucked into the filter basket 3, the gravity of the garbage is not enough to deform the flexible barrier strip 35 outwards, so that the garbage can be prevented from escaping. It should be noted that the flexible barrier strip 35 can be installed in installing holes formed in the filter basket 3 via a plurality of installing buckles, and the flexible barrier strip 35 can be installed on the inner side or outer side of the filter basket 3. In the case that the flexible barrier strip 35 is installed on the inner side of the filter basket 3, when the flexible barrier strip 35 is deformed inwards, only the connection position of the installing buckles can restrict the flexible barrier strip 35, so that the flexible barrier strip 35 can obtain a larger deformation range, and then larger garbage can be sucked into the filter basket through the inlet, which can realize a good sealing effect, that is, prevent the garbage from escaping through the inlet, and facilitate the garbage enter the filter basket through the inlet.
[0032] As shown in FIG. 9, the filter basket 3 is integrally of a hollow-out structure. A filter screen can be arranged at each hollow-out hole to ensure that water can flow freely and the garbage and other sundries sucked into the filter basket 3 can be remained inside the filter basket 3. A chemical dosing box 34 filled with solid chemicals can be arranged at the bottom of the filter basket 3, so that the water environment can be sterilized by the chemicals. A chemical box cover 341 can be arranged on the top of the chemical dosing box 34. The chemical box cover 341 can be connected to protrusions on the chemical dosing box 34 through V-shaped grooves formed in the peripheral wall of the chemical box cover 341 to realize connection between the chemical dosing box 34 and the chemical box cover 341, so that the chemicals can be restricted in the space formed by the chemical dosing box 34 and the chemical box cover 341. The chemical box cover 341 can be solid or provided with hollow-out holes. The bottom of the chemical dosing box 34 is shared with the bottom of the filter basket 3 and provided with the hollow-out holes, so that the chemicals can be gradually dissolved and then enter water outside of the water surface cleaning device.
[0033] As shown in FIG. 13, the rolling brush 4 includes a central shaft 41 and guide vanes radially distributed on the central shaft 41. The shape of the guide vane can be in various forms. For example, the guide vanes are all sheet-like guide vanes 42, the guide vanes are all columnar guide vanes 43, the guide vanes are in the forms of hairbrushes, the guide vanes are all elliptical guide vanes, or the guide vanes include sheet-like guide vanes 42 and columnar guide vanes 43. In the case that the guide vanes include sheet-like guide vanes 42 and columnar guide vanes 43, the width of the sheet-like guide vane 42 is wider than that of the columnar guide vane 43, and the sheet-like guide vanes 42 and the columnar guide vanes 43 are distributed at intervals in the axial direction and circumferential direction, so that the rotation resistance can be reduced, and the garbage floating on the water surface can also be collected better. In addition, the thickness of the middle part of the guide vane can be equal to that of the edge of the guide vane, or the thickness of the middle part of the guide vane can be larger than that of the edge of the guide vane, so that the strength of the guide vane can be improved. As the strength of the guide vane is improved, the guide vane with longer radial extension length can be arranged, so that a larger inlet area can be covered, that is, an inlet with a larger size can be formed, so that garbage is collected more conveniently.
[0034] As shown in FIG. 14, the main body 1 is provided with a watertight cabin 6 and a short wire groove 7. The watertight cabin 6 is in a higher watertight grade, so that, water is avoided from entering into the watertight cabin 6 to influence normal operation of electronic components, such as the power supply and the controller, arranged in the watertight cabin 6. Different wires are led into the short wire groove 7 to be gathered into a multi-core wire and led out, and the multi-core wire is connected to the watertight cabin 6 via a watertight joint. Thus, the number of wires entering the watertight cabin 6 can be effectively reduced, the number of wire holes 612 needed to be sealed in the watertight cabin 6 can be reduced, so that the possibility of water entering the watertight cabin 6 can be reduced.
[0035] Furthermore, the watertight cabin 6 is connected to the main body 1 by means of a detachable structure, such as screw connection. The watertight cabin 6 includes a cabin body 62 and a cabin cover 61. The cabin body 62 is provided with a connecting structure 621. The connecting structure 621 is installed on the main body 1 via screws to realize detachable installation of the cabin body 62. The cabin cover 61 may be provided with a watertight and breathable structure 611, so that the stability of the watertight cabin 6 still can be maintained when pressure changes or water vapor is generated in the watertight cabin 6 since temperature changes therein The multi-core wire can be connected to the watertight cabin 6 by means of a detachable structure, such as a quick connector. With the above arrangement, when the controller or the power supply fails, only the watertight cabin 6 needs to be removed for replacement or maintenance, which is convenient for later maintenance and repair.
[0036] As shown in FIG. 3, FIG. 4, FIG. 6, FIG. 11A, FIG. 11B and FIG. 16, the propellers 5 are arranged on the left and right sides of the main body 1 in parallel. The propellers 5 on both sides work simultaneously to form thrust force to push the water surface cleaning device to travel. The propeller 5 includes a barrel cabin 51. The barrel cabin 51 is cylindrical. Both ends of the barrel cabin 51 are opened to form a perforated water flow channel. The barrel cabin 51 is internally provided with an axial flow blade 53 coaxially connected to a second motor located in the barrel cabin 51. It should be noted that in the case that the axial flow blades 53 of the two propellers 5 rotate in the same direction (counterclockwise or clockwise), the whole water surface cleaning device may be deflected. However, due to the small volume of the water surface cleaning device 1, the relative distance between the two axial flow blades 53 is not large, and the caused deflection force can be ignored. In addition, the two axial flow blades 53 rotating in the same direction can facilitate installation, reduce the development cost of the mold, and thus can be adopted. In fact, the stability of the operation state can be best maintained in the case that the axial flow blades 53 of the two propellers 5 rotate in different directions that is, the axial flow blades 53 of the two propellers 5 rotates counterclockwise and clockwise respectively. Therefore, in application, the two axial flow blades 53 rotating in the different directions can be adopted without consideration of the cost. Baffles 52 are respectively arranged at both ends of the barrel cabin 51, and the baffle 52 includes an annular ring 521 connected to the barrel cabin 51 and spokes 522 arranged on the inner-diameter side of the annular ring 521. The number of the spokes 522 can be three or more. The spokes 522 can prevent garbage or sundries from entering the barrel cabin 51 to a certain extent, thus preventing the garbage or sundries from interfering with the rotation of the axial flow blades 53.
[0037] As shown in FIG. 11A, the baffle 52 is connected to the barrel cabin 51 via a quick-release structure. The quick-release structure includes an annular guide groove 511 arranged on the barrel cabin 51 and an annular guide block 5211 arranged on the annular ring 521. The annular guide groove 511 corresponds to the annular guide block 5211 in position. The annular guide groove 511 faces towards the outer-diameter side of the barrel cabin 51 and is provided with an annular guide port and a limiting part. The annular guide block 5211 faces towards the inner-diameter side of the barrel cabin 51, can enter the annular guide groove 511 through the guide port, and slides in the annular guide groove 511. The annular guide groove 511 is internally provided with a wedge-shaped block. A wedge-shaped groove is formed in the annular guide block 5211. After the annular guide groove 511 and the annular guide block 5211 rotate in place, the wedge-shaped block can be clamped in the wedge-shaped groove to realize circumferential limit, so that the installation of the annular guide groove 511 and the annular guide block 5211 is relatively convenient. After the baffle 52 is twisted reversely by force, the wedge-shaped block can be separated from the wedge-shaped groove, and then the baffle 52 can be quickly disassembled.
[0038] As shown in FIG. 11B, the baffle 52 can also be of another quick-release structure. Specifically, the other quick-release structure includes an annular guide groove 511 arranged on the barrel cabin 51 and an annular guide block 5211 arranged on the annular ring 521. The annular guide groove 511 corresponds to the annular guide block 5211 in position. Axial through holes are formed in the annular guide groove 511. The through hole includes expanding holes and reducing holes which are circumferentially connected and distributed. The annular guide block 5211 extends in the axial direction, can enter the annular guide groove 511 through the expanding holes, and slides in the annular guide groove 511. The annular guide block 5211 is an elastic column with radially deformable elasticity, and a free end of the elastic column is expanded to form a clamping joint. The elastic column penetrates through the expanding hole and rotates along the annular guide groove 511. After the elastic column rotates in place, the elastic column can be clamped into the reducing hole to realize circumferential limit, which is convenient to install. Furthermore, after the baffle 52 is twisted reversely by force, the elastic column can be separated from the reducing hole, so that the baffle 52 can be quickly disassembled.
[0039] By means of the arrangement of the installing structure of the baffle 52 as shown in FIG. 11A and FIG. 11B, it is convenient to disassemble the baffle 52, clean the sundries in the barrel cabin 51, repair the second motor and the axial flow blade 53, and then install the baffle 52.
[0040] As shown in FIG. 1 and FIG. 3 to FIG. 5, the main body 1 is provided with a front anti-collision strip 13 and side anti-collision strips 14 arranged on the left and right sides thereof. The anti-collision strip is made of soft rubber such as silica gel, rubber or TPU (thermoplastic polyurethane elastomer), which can play the roles of shock absorption and buffering to avoid bumping damage. Anti-collision wheels 15 are arranged on both sides of the inlet of the filter basket 3 in front of the main body 1. The anti-collision wheels 15 are installed in grooves formed in the main body 1 via C-shaped frames and are horizontally and rotatably arranged. Once the left front side or the right front side of the water surface cleaning device hit an obstacle, the anti-collision wheels 15 can rotate to avoid the obstacle.
[0041] As shown in FIG. 4 and FIG. 16, an anti-grounding structure 19 is arranged below the main body 1, and the anti-grounding structure 19 is provided with a telescopic column 191. The telescopic column 191 is provided with an elastic buckle 1911.
