SUMMARY

[0006] The technical problem to be solved by the present application is to provide a shower top spray water drain device, which can avoid the problem of residual water in the shower cavity being difficult to drain for a long time by sliding the drain piston inside the water sealing seat, so that the movable part can slide axially along the drain hole, thereby controlling whether the drain hole is connected to the shower cavity.

[0007] To solve the above technical problems, the technical scheme of the present application is:

[0008] A shower top spray water drain device, comprising a water sealing seat and a drain piston slidingly arranged inside the water sealing seat, the water sealing seat is installed inside the shower face cover, the side surface of the water sealing seat is provided with a water outlet hole communicating with the shower face cover, the front end of the water sealing seat is provided with a water inlet hole communicating with the water outlet hole, and the rear end of the water sealing seat is provided with a plurality of drain holes communicating with the water outlet hole, the drain piston comprises a movable part and a sealing part integrally connected with the movable part, and the movable part is inserted into the drain hole.

[0009] Preferably, the sealing part is clamped on the inner side of the water sealing seat, and the sealing part is conical.

[0010] Preferably, a circular groove is formed on the outer side of the sealing part.

[0011] Preferably, a piston clamping groove matched with the sealing part is formed on the inner side of the water sealing seat.

[0012] Preferably, a plurality of mounting legs are arranged on the outer side of the water sealing seat, and the mounting legs are distributed on the outer side of the water sealing seat along the circular edge.

[0013] Preferably, a plurality of circular arc grooves are formed on the inner side of the drain hole, and the circular arc grooves are distributed on the inner side of the drain hole in the form of square vertices.

[0014] By adopting the above technical solution, the shower head drainer provided by the present invention has the following beneficial effects: the water sealing seat in the shower head drainer is installed inside the shower head cover, the side of the water sealing seat has a water outlet hole communicating with the shower head cover, the front end of the water sealing seat has a water inlet hole communicating with the water outlet hole, and the rear end of the water sealing seat has several drain holes communicating with the water outlet hole. The drain piston includes a movable part and a sealing part integrally connected with the movable part. The movable part is inserted into the drain holes, and the drain piston is slidably mounted on the water sealing seat. The inner side of the shower head is designed so that the moving part can slide axially along the drain hole, thereby controlling whether the drain hole is connected to the shower head cavity. When the shower head valve is opened, water flows from the inlet hole into the sealing seat and from the outlet hole to the shower head cover. At this time, the drain piston seals the drain hole, and the inlet hole and outlet hole are connected. When the shower head valve is closed, the drain piston disengages from the drain hole, and the outlet hole and drain hole are connected. The water accumulated in the shower head can be discharged through the drain hole, thus avoiding the situation where residual water in the shower head cavity cannot be drained for a long time. It can easily drain the residual water in the shower head cavity, resulting in a better user experience. Attached Figure Description

[0021] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] like Figures 1-5 As shown, the device includes a water-sealing base 1 and a drain piston 2 slidably disposed inside the water-sealing base 1. The water-sealing base 1 is installed inside the shower head cover. A water outlet hole 3 communicating with the shower head cover is opened on the side of the water-sealing base 1. A water inlet hole 4 communicating with the water outlet hole 3 is opened at the front end of the water-sealing base 1. A plurality of drain holes 5 communicating with the water outlet holes 3 are opened at the rear end of the water-sealing base 1. The drain piston 2 includes a movable part 6 and a sealing part 7 integrally connected to the movable part 6. The movable part 6 is inserted into the drain holes 5. It is understood that the water-sealing base 1 can be made of plastic, etc., and the drain piston 2 can be made of rubber, etc.; this invention is not limited thereto.

[0025] Specifically, the sealing part 7 is snapped into the inner side of the water sealing base 1. The sealing part 7 is conical in shape, and a circular groove 8 is provided on the outer side of the sealing part 7. A piston snapping groove 9 that matches the sealing part 7 is provided on the inner side of the water sealing base 1. Several mounting feet 10 are provided on the outer side of the water sealing base 1. The mounting feet 10 are distributed sequentially along the circular edge of the outer side of the water sealing base 1 to facilitate fixing the water sealing base 1. Several arc grooves 11 are provided on the inner side of the drain hole 5. The vertices of the arc grooves 1 are square and sequentially distributed on the inner side of the drain hole 5. Understandably, when the shower valve is opened, water flows from the inlet hole 4 into the sealing seat 1, and then flows out from the outlet hole 3 to the shower head cover. At this time, the drain piston 2 is pushed backward by the water pressure to seal the drain hole 5, and the inlet hole 4 and the outlet hole 3 are connected. When the shower valve is closed, the drain piston 2 rebounds and disengages from the drain hole 5, and the outlet hole 3 is connected to the drain hole 5. At this time, the water accumulated in the shower head can be discharged through the drain hole 5.

[0026] It can be understood that the present application is reasonable in design and unique in structure. The water outlet piston 2 is slidably arranged on the inner side of the water sealing seat 1, so that the movable part 6 can slide axially along the water outlet through hole 5, thereby controlling whether the water outlet through hole is communicated with the inner cavity of the shower head. Thus, the situation that the residual water in the inner cavity of the shower head cannot be completely drained for a long time is avoided. The residual water in the inner cavity of the shower head can be conveniently drained, and the user experience effect is good.

[0027] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations of the embodiments can be made without departing from the principles and spirits of the present application, and still fall within the protection scope of the present application.
