DETAILED DESCRIPTION

[0029] In order to make objects, technical solutions and advantages of the present application clearer, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other if there is no conflict.

[0030] An embodiment of the present application provides a water outlet device. As shown in FIGS. 1 to 19, the water outlet device includes a shell, a water storage chamber 23 is disposed in the shell, an inlet 11 of the shell is communicated with the water storage chamber 23 through a first flow path 21, the water storage chamber 23 is communicated with an outlet 24 of the shell through a second flow path 22, and the liquid in the water storage chamber 23 overflows after being fully filled and flows to the outlet 24 of the shell through the second flow path 22. The first flow path 21 and/or the second flow path 22 are provided with a flow adjustment structure which is disposed to adjust a flow state of the liquid.

[0031] The water supply enters the inside of the shell through the inlet 11 of the shell, and then enters the water storage chamber 23 through the first flow path 21. After fully filling the water storage chamber 23, the water overflows into the second flow path 22, and finally forms a water curtain at the outlet 24 of the shell and is discharged out of the shell.

[0032] The water storage chamber 23 disposed in the shell is used for storing water. Additionally, by means of overflowing from the water storage chamber 23 after the water fully fills the water storage chamber 23, the water storage chamber 23 ensures that when the water pressure or the water flow is relatively small, the water first converges and fully fills in the water storage chamber 23 and then overflows, thus forming a relatively wide water flow (water curtain) and forming a water curtain at the outlet 24 of the shell.

[0033] In practical application, a side of the water storage chamber 23 close to the second flow path 22 may be provided with an edge with uniform height, so that the water can evenly overflow from the edge at said side after fully filling the water storage chamber 23, to form a relatively wide water flow. The water storage chamber 23 may be a structure separately enclosed and formed by one member, as shown in FIG. 19. At this point, a wall surface on a left side of the water storage chamber 23 (i.e. S1 in FIG. 19) is disposed to be uniform in height in a circumferential direction, so as to facilitate the uniform overflow of the water in the water storage chamber 23 after being fully filled (the water in the water storage chamber 23 overflows simultaneously in a width direction of the flow path). The water storage chamber can also be a structure enclosed and formed by two members, as shown in FIG. 8. At this point, a part of a water outlet nozzle 3 inclined rightwards and upwards forms the wall surface on the left side of the water storage chamber 23, and the part of the water outlet nozzle 3 inclined rightwards and upwards is disposed to be uniform in height in the circumferential direction, so that the water in the water storage chamber 23 overflows simultaneously in the width direction of the flow path, which facilitates subsequent formation of a relatively wide water curtain.

[0034] The flow adjustment structure disposed inside the shell can be used to adjust the flow state of the liquid. In other words, the flow adjustment structure can be used to disperse and adjust the water flow, and play a certain role on blocking of the excessively fast water flow (for example, when the water pressure inside the water outlet device is too high).

[0035] The flow adjustment structure may be disposed only on the first flow path 21 or only on the second flow path 22, or may be provided both on the first flow path 21 and the second flow path 22.

[0036] Through the cooperation of the water storage chamber 23 and the flow adjustment structure, the water outlet device can form a continuous and stable water curtain when the water pressure is too high or too low, thus reducing the influence of self-water pressure on the water curtain type of water outlet and improving the use experience of users.

[0037] In the water outlet device provided by the embodiment of the present application, a water storage chamber 23 is disposed in front of the outlet 24 of the shell, and the water storage chamber 23 is used for storing water. After the water is fully filled in the water storage chamber 23, the water overflows to the outlet 24 of the shell to form a water curtain, thus ensuring that a continuous and stable water curtain can still be formed at the outlet 24 of the shell when the water pressure is relatively low and the water supply in the water outlet device is insufficient (the water pressure is relatively low). A flow adjustment structure is also disposed in the water outlet device, and the flow adjustment structure can be used for dispersing, adjusting the water flow and blocking excessively fast water flow, thus preventing excessive water pressure from destroying the water curtain, and ensuring that a continuous and stable water curtain can still be formed at the outlet 24 of the shell when the water pressure is relatively high.

[0038] In an exemplary embodiment, as shown in FIGS. 3 and 4, a plurality of guidance protrusions 211 are disposed on the first flow path 21, and passage gaps 212 for liquid to flow are formed between adjacent guidance protrusions 211. The flow adjustment structure includes the guidance protrusions 211.

[0039] The guidance protrusions 211 disposed on the first flow path 21 block the water flow to a certain extent, and the water will be blocked when the water on the first flow path 21 flows through the guidance protrusions 211, and then pass through the passage gaps 212 between the adjacent guidance protrusions 211 and enter the subsequent water storage chamber 23.

[0040] When the guidance protrusions 211 block the water flow, the guidance protrusions 211 can slow down the water flow with excessive speed, so as to avoid the water flow being too rapid and affecting the formation of the subsequent water curtain. The guidance protrusions 211 have less blocking effect on the slower water flow and will not affect the normal flow of the slower water flow.

[0041] In an exemplary embodiment, as shown in FIGS. 3 and 4, a plurality of guidance protrusions 211 are provided in a direction perpendicular to an extension direction of the first flow path 21; and/or the guidance protrusions 211 are provided in one or more rows in the extension direction of the first flow path 21.

[0042] The plurality of guidance protrusions 211 are provided in the direction perpendicular to the extension direction of the first flow path 21. In other words, the plurality of guidance protrusions 211 are provided in a width direction of the water flow, so that the guidance protrusions 211 play a role of buffering and blocking for all the water flow in the entire width direction.

[0043] The plurality of guidance protrusions 211 may be uniformly arranged in the direction perpendicular to the extension direction of the first flow path 21. In other words, the widths of the passage gaps 212 are equal.

[0044] The guidance protrusions 211 are provided in one or more rows in the extension direction of the first flow path 21. In other words, the guidance protrusions 211 are provided in one or more rows in the flowing direction of the water flow. The guidance protrusions 211 are specifically disposed in one or several rows, which can be adjusted according to actual conditions (such as the water pressure range of the water outlet device, etc.).

[0045] In an exemplary embodiment, as shown in FIGS. 3 and 4, the guidance protrusions 211 are provided in a plurality of rows in the extension direction of the first flow path 21, and the passage gaps 212 in adjacent rows are staggered.

[0046] The passage gaps 212 in adjacent rows are staggered. In other words, the water flowing through the passage gaps 212 in the previous row will hit the guidance protrusions 211 in the subsequent row as it continues to flow. The staggered arrangement of the passage gaps 212 can greatly improve the buffering and blocking effect of the guidance protrusions on the water flow with excessive speed.

[0047] In an exemplary embodiment, first water blocking columns are provided on the first flow path 21 and the first water blocking columns are disposed to reduce the flow rate of the liquid. The flow adjustment structure includes the first water blocking columns.

[0048] The first flow path 21 is also provided with first water blocking columns for further reducing the speed of the water flow, and the first water blocking columns are fitted with the guidance protrusions 211 to ensure that the water flow stably enters the water storage chamber 23, so as to avoid the formation of the water curtain being influenced by a considerable fluctuation of the water flow in the water storage chamber 23.

[0049] In an exemplary embodiment, as shown in FIGS. 3-6, the first water blocking columns include a first raised column body 213 and a second raised column body 13 disposed opposite to each other, and the first raised column body 213 and the second raised column body 13 are staggered to form a passage channel.

[0050] In a height direction of the water outlet device, the first raised column body 213 can extend from top to bottom, the second raised column body 13 can extend from bottom to top, and the first raised column body 213 and the second raised column body 13 are staggered to form a passage channel winding in height direction. The water flow passes through the passage channel and can be effectively slowed down and adjusted.

[0051] It should be understood that the first raised column body 213 and the second raised column body 13 may be disposed differently. For example, in the width direction of the water outlet device, the first raised column body 213 may extend from left to right, the second raised column body 13 may extend from right to left, and the first raised column body 213 and the second raised column body 13 may be staggered to form a passage channel winding in a left-right direction.

[0052] In an exemplary embodiment, as shown in FIGS. 5 and 6, the second flow path 22 is provided with second water blocking columns 14 disposed to reduce the flow rate of the liquid. The second water blocking columns 14 are disposed at an end of the second flow path 22 away from the outlet 24 of the shell. The flow adjustment structure includes the second water blocking columns 14.

[0053] The second water blocking columns 14 are provided on the second flow path 22 to slow down the flow rate of the water overflowing out of the water storage chamber 23. It should be understood that the second water blocking columns 14 are disposed on the second flow path 22. When the shell includes an upper cover 1 and a lower cover 2, the second water blocking columns 14 can be disposed on either the upper cover 1 or the lower cover 2, both of which belong to the second flow path 22 in position. As shown in FIGS. 5 and 6, the second water blocking columns 14 are disposed on the upper cover 1.

[0054] The second water blocking columns 14 are disposed at an end of the second flow path 22 away from the outlet 24 of the shell, that is, the second water blocking columns 14 are disposed at a side of the second flow path 22 close to the water storage chamber 23. The water overflows from the water storage chamber 23, passes through the second water blocking column 14, and then flows for a certain distance before reaching the outlet 24 of the shell, so as to ensure that the water after passing through the second water blocking columns 14 can flow for a certain distance to uniformly meet, and to ensure that the water flow is a continuous and integral water curtain in the width direction.

[0055] In an exemplary embodiment, as shown in FIGS. 8 to 12, the water outlet device further includes a water outlet nozzle 3 mounted on the shell, and the water outlet nozzle 3 is provided with a strip-shaped water outlet port 32. The water outlet port 32 forms the outlet 24 of the shell.

[0056] FIGS. 1 to 12 show a water outlet device with a water outlet nozzle 3, and FIGS. 13 to 19 show a water outlet device without a water outlet nozzle 3 (i.e., a water outlet port 32 is provided directly on the shell as the outlet 24 of the shell).

[0057] The water outlet nozzle 3 serves as a separate member, and a strip-shaped water outlet port 32 is provided on the water outlet nozzle 3 as the outlet 24 of the shell so that the water flow forms a water curtain here.

[0058] The water outlet nozzle 3 is made as a separate member, which facilitates the processing of the strip-shaped water outlet port 32, thus reducing the manufacturing cost.

[0059] A corresponding opening can be provided on the shell, and the water outlet nozzle 3 is installed at the position of the opening of the shell.

[0060] In an exemplary embodiment, as shown in FIGS. 11 and 12, a plurality of first reinforcement ribs 31 are arranged at intervals along a length direction within the water outlet port 32.

[0061] The water outlet port 32 has an elongated-strip shape, and a plurality of first reinforcement ribs 31 are disposed in the water outlet port 32, so that the shape of the water outlet port 32 can be ensured to be stable, so as to avoid the failure of formation of water curtain type of water outlet due to the deformation of the water outlet port 32 caused by the squeeze to the water outlet port 32 during installation or use.

[0062] It should be noted that, in the height direction of the water outlet device, the height of the first reinforcement rib 31 may be smaller than the height of the water outlet port 32. In other words, an upper surface of the first reinforcement rib 31 is flush with an upper surface of the water outlet port 32, and a lower surface of the water outlet port 32 is lower than a lower surface of the first reinforcement rib 31, so that a lower end of the water outlet port 32 is an integral opening without being cut off by the first reinforcement rib 31, thus ensuring that the water outlet can form an integral water curtain without being cut off.

[0063] The following is described in detail in combination with FIGS. 8 and 12.

[0064] In FIG. 8, the first reinforcement rib 31 and the water outlet nozzle 3 form an integrated structure. The water outlet port 32 in FIG. 8 is not shown as the full height (i.e., only part of the water outlet port can be seen in the height direction) due to the view angle of the sectional view, and an upper part of the water outlet port is blocked by the first reinforcement rib 31 and cannot be seen. In other words, in FIG. 8, the water outlet port 32 penetrates through the water outlet nozzle 3 in the height direction to ensure water path communication. The positional relationship between the first reinforcement rib 31 and the water outlet port 32 can be easily seen with reference to FIG. 12. In an exemplary embodiment, as shown in FIG. 9, an end of the water outlet nozzle 3 facing away from the water outlet port 32 extends upward obliquely, and the water storage chamber 23 is enclosed and formed by the end and the shell.

[0065] An end of the water outlet nozzle 3 and the shell enclose and form the water storage chamber 23, which simplifies the structure of the shell. After the water is fully filled in the water storage chamber 23, the water overflows to the water outlet port 32 along an end of the water outlet nozzle 3 to form a water curtain.

[0066] The inclined portion of the water outlet nozzle 3 serves as the second flow path 22 communicated with the water storage chamber 23 and the water outlet port 32.

[0067] In an exemplary embodiment, as shown in FIGS. 13 to 15, the shell is provided with a strip-shaped water outlet hole 241. The water outlet hole 241 forms the outlet 24 of the shell.

[0068] In practical application, the water outlet nozzle 3 may not be provided, that is, a strip-shaped water outlet hole is directly provided on the shell as the outlet 24 of the shell to form a water curtain type of water outlet.

[0069] By directly providing the strip-shaped water outlet hole 241 on the shell, the number of components of the water outlet device can be reduced (i.e., the water outlet nozzle 3 is omitted), the manufacturing cost can be reduced, the assembly process can be simplified, the sealing performance can be improved, and problems such as water leakage at the outlet 24 can be avoided.

[0070] In an exemplary embodiment, as shown in FIGS. 16 and 17, a plurality of second reinforcement ribs 12 are provided on the shell, and the plurality of second reinforcement ribs 12 are arranged at intervals along a length direction of the water outlet hole 241. The plurality of second reinforcement ribs 12 are inserted into an end of the water outlet hole 241 facing the shell.

[0071] The shell is directly provided with a strip-shaped water outlet hole 241 as the outlet 24 of the shell, and the second reinforcement ribs 12 provided on the shell can be inserted into the water outlet hole 241 to support the water outlet hole 241, so as to avoid the deformation of the water outlet hole 241 caused by squeeze during assembly or use of the water outlet device. For example, when the shell includes an upper cover 1 and a lower cover 2 which are buckled, the water outlet hole 241 can be provided on the lower cover 2, and the second reinforcement ribs 12 can be provided on the upper cover 1. When the upper cover 1 is buckled with the lower cover 2, the second reinforcement ribs 12 on the upper cover 1 are inserted into the water outlet hole 241 of the lower cover 2 to support the water outlet hole 241.

[0072] It should be understood that the second reinforcement ribs 12 can also be directly provided in the water outlet hole 241. For example, when the shell includes the upper cover 1 and the lower cover 2 which are buckled, the water outlet hole 241 can be provided on the lower cover 2, and the second reinforcement ribs 12 can be provided in the water outlet hole 241. In other words, the second reinforcement ribs 12 and the lower cover 2 can form an integrated member.

[0073] In an exemplary embodiment, as shown in FIG. 19, in the liquid flow direction, an upstream end of the water outlet hole 241 is provided with a guidance ramp 25. A diameter of a downstream end of the water outlet hole 241 is smaller than a diameter of the upstream end of the water outlet hole 241. In other words, an end of the water outlet hole 241 facing the shell is provided with a guidance ramp 25. A diameter of the end of the water outlet hole 241 facing away from the shell is smaller than a diameter of the end of the water outlet hole 241 facing the shell.

[0074] The end of the water outlet hole 241 facing the shell is provided with a guidance ramp 25, so as to facilitate the insertion of the second reinforcement ribs 12 on the shell into the water outlet hole 241 and to play a guiding role and reduce the assembly difficulty.

[0075] The diameter of an end of the water outlet hole 241 facing away from the shell is smaller than the diameter of an end of the water outlet hole 241 facing the shell, so as to satisfy both "insertion of the second reinforcement ribs 12 into the end of the water outlet hole 241 facing away from the shell" and "water curtain type of water outlet at the end of the water outlet hole 241 facing the shell".

[0076] In an exemplary embodiment, the shell includes an upper cover 1 and a lower cover 2 that are buckled and connected. The upper cover 1 is provided with an inlet 11 of the shell. The lower cover 2 is provided with an outlet 24 of the shell, as shown in FIGS. 13 to 19. Alternatively, the lower cover 2 is mounted with a member provided with an outlet 24 of the shell, as shown in FIGS. 1 to 12.

[0077] The water supply enters the water outlet device from the upper cover 1 and flows out of the lower cover 2 in the form of a water curtain.

[0078] For the outlet 24 of the shell at the lower cover 2, the lower cover 2 may be provided with the outlet 24 of the shell, that is, the water outlet hole 241 is provided directly in the lower cover 2 (the water outlet nozzle 3 is omitted). Alternatively, the lower cover 2 may be mounted with a member provided with the outlet 24 of the shell, that is, the water outlet nozzle 3 is connected to the lower cover 2, and the water outlet port 32 is provided on the water outlet nozzle 3 to serve as the outlet 24 of the shell.

[0079] In an exemplary embodiment, as shown in FIGS. 3 and 15, the lower cover 2 is provided with a cavity with an opening facing upwards, and the cavity includes a water passage area 26 and a support area 27 that are independent of each other. The water storage chamber 23, the first flow path 21 and the second flow path 22 are all disposed in the water passage area 26. The upper cover 1 is buckled at the opening of the lower cover 2.

[0080] The water passage area 26 is used for water flow, while the support area 27 has no water flow. The support area 27 plays a role of separation and support. In practical application, the proportion of the water passage area 26 and the support area 27 can be adjusted according to the requirements for the width of the water curtain, the water pressure in the water outlet device and the like.

[0081] In an exemplary embodiment, as shown in FIGS. 3 and 15, the support area 27 is fan-ring shaped.

[0082] The lower cover 2 may be a cylindrical member with a relatively small thickness, i.e. the lower cover 2 is circular in cross section. The support area 27 is fan-ring shaped, and the remaining part is the water passage area 26.

[0083] In the cross-section of the lower cover 2, the middle area of the circle corresponds to the water inlet port on the upper cover 1 (i.e. the inlet 11 of the shell). In other words, the shape of the water passage area 26 may be "fan-ring + circle".

[0084] Obviously, in practical application, the shapes of the water passage area 26 and the support area 27 may be adjusted. For example, the shapes of the water passage area 26 and the support area 27 may be both configured to be fan-shaped, which is not limited in the present application.

[0085] In an exemplary embodiment, as shown in FIGS. 1 and 14, the outlet 24 of the shell is circular arc-shaped.

[0086] The outlet 24 of the shell is configured to be circular arc-shaped, i.e. the water outlet device may eventually form a circular arc-shaped water curtain.

[0087] Alternatively, the outlet 24 of the shell may also be straight line-shaped so that the water outlet device may eventually form a straight line-shaped water curtain. In addition, the shape of the outlet 24 of the shell can be adjusted according to the requirements. For example, the outlet 24 of the shell can also be fold line-shaped, wavy line-shaped or other shapes.

[0088] An embodiment of the present application also provides a shower apparatus, which includes the water outlet device described above.

[0089] The shower apparatus provided by the embodiment of the present application is provided with the water outlet device described above, which can form a continuous and stable water curtain during use, is less affected by the self-water pressure, works stably and reliably, and improves the showering experience of users.

[0090] The shower apparatus can be a shower.
