Description

Technical Field

[0001] This utility model relates to water outlet devices, and more particularly to overhead shower heads. Background Technology

[0002] Existing showerheads often leave residual water after use. This can cause the showerhead to suddenly leak out when shaken or bumped, leading to unnecessary trouble or causing residual water to spray onto the user when the showerhead is turned on. This greatly affects the user experience. Furthermore, the residual water that cannot be drained in time usually contains more impurities and bacteria, which may affect the user's health when sprayed onto the body, reducing the safety and practicality of the showerhead.

[0003] Therefore, showerheads that can drain residual water after the water is turned off have appeared on the market. However, existing residual water drainage functions have the following problems:

[0004] Firstly, after the water is turned off, no outside air is introduced into the cavity, which can easily create a vacuum inside the cavity, making it difficult for residual water to drain out. At the same time, during rapid drainage, there is a continuous dripping phenomenon near the quick drainage hole.

[0005] Secondly, after turning off the water, you need to tilt the shower head to allow the remaining water to flow out.

[0006] Thirdly, in addition to flowing out from the quick-drain outlet, some residual water will also enter the water outlet and drip slowly, causing continuous dripping. Utility Model Content

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0039] refer to Figures 1-10 This embodiment provides a top spray shower head that drains residual water, including: a shower head body 1, a slider 2, a push plate 3, a pressure plate 4, and a water outlet cover assembly 5;

[0040] The slider 2 is disposed in the water channel of the shower body 1 and moves from the first position to the second position under the action of water pressure; the slider 2 and the push plate 3 are engaged by a first reversing structure 6, and the push plate 3 and the pressure plate 4 are engaged by a second reversing structure 7; the first reversing structure 6 and the second reversing structure 7 move the slider 2 along the direction from the first position to the second position, and the reversing structure 7 moves the pressure plate 4 along the direction from the third position to the fourth position;

[0041] The water outlet cover assembly 5 is provided with a vent 51 and a residual water drain 52, wherein the residual water drain 52 penetrates the water outlet cover assembly 5 along the thickness direction of the water outlet cover assembly 5, and the vent 51 does not penetrate the water outlet cover assembly 5. When the pressure plate 4 is in the third position, the vent 51 and the residual water drain 52 are opened; when the pressure plate 4 is in the fourth position, the vent 51 and the residual water drain 52 are closed by the pressure plate 4.

[0042] The aforementioned overhead shower head that drains residual water moves the pressure plate 4 by adjusting the position of the slider 2 under water pressure, creating an effect similar to opening and closing a door. This allows the pressure plate 4 to open the vent 51 and residual water drain 52 to drain water when the water is turned off, and close them when the water is turned on for normal showering. This achieves the effect of quickly draining residual water.

[0043] In this embodiment, the vent 51 and residual water drain 52 are located at both ends of the same diameter of the water outlet cover assembly 5. To allow simultaneous opening or closing of the vent 51 and residual water drain 52, the push plate 3 is positioned on both sides of the slider 2, with the contact surface between the slider 2 and the push plate 3 being an inclined plane forming the first reversing structure 6. The pressure plate 4 is positioned on the side of the push plate 3 away from the slider 2, with the contact surface between the pressure plate 4 and the slider 2 being an inclined plane forming the second reversing structure 7. Thus, when the slider 2 moves from the first position to the second position under water pressure, the push plate 3 can be moved horizontally away from the slider 2 via the first reversing structure 6. The push plate 3 then drives the pressure plate 4 to flip from the third position to the fourth position via the second reversing structure 7.

[0044] The above structure only allows the slider 2 to move from the first position to the second position. When the water pressure is low, the slider 2, push plate 3, and pressure plate 4 need to reset. Therefore, in this embodiment, a flow-limiting hole 21 is formed between the slider 2 and the inner wall of the shower head body 1. When the slider 2 moves from the first position to the second position, the flow area of ​​the flow-limiting hole 21 gradually increases. When the water is turned off, the water pressure at the upper end of the slider 2 is 0, while the water pressure at the lower end is not zero due to residual water. Under the action of the pressure difference, the slider 2 moves upward along the second position to achieve reset. The push plate 3 is connected to the first reset member 31. When the slider 2 is in the second position, the push plate 3 squeezes the first reset member 31 to accumulate elastic reset. The pressure plate 4 is connected to the second reset member 41. When the pressure plate 4 is in the fourth position, the second reset member 41 accumulates elastic reset force.

[0045] In this embodiment, the first reset element 31 is a spring, and due to the flipping motion of the pressure plate 4, the second reset element 41 is a torsion spring. Thus, during the flipping process, the torsion spring 41 can be pressed to accumulate elastic reset force.

[0046] In this embodiment, to achieve the sealing of the vent 51 and the residual water drain 52 by the pressure plate 4, the pressure plate 4 includes a pressure plate body 42 and a soft rubber pad 43; the soft rubber pad 43 is fixed on the side of the pressure plate body 42 facing the water outlet cover assembly 5; when the pressure plate 4 is in the fourth position, since there are two pressure plates 4, the soft rubber pads 43 of the two pressure plates 4 respectively seal with the residual water drain 52 and the vent 51 to close the residual water drain 52 and the vent 51. In order to achieve the above-mentioned sealing effect, a sealing strip 53 that cooperates with the soft rubber pad 43 is also provided on the outer periphery of the residual water drain 52 and the vent 51.

[0047] To install the torsion spring, pressure plate shafts 421 are respectively provided on both sides of the pressure plate body 42; the torsion spring is sleeved on the pressure plate shafts 421, with one arm of the torsion spring abutting against the water outlet cover assembly 5 and the other arm abutting against the pressure plate body 42. Specifically, a protrusion 422 extends from the side of the pressure plate 4 in the area outside the pressure plate shafts 421, and the other arm is inserted into the protrusion 422.

[0048] Furthermore, the shower head body 1 is provided with a ball head assembly 8 connected to the water inlet. The ball head assembly 8 restricts the swing angle of the shower head body 1 through a limiting seat 81, so that when the shower head body 1 deviates from the horizontal position, the residual water drain outlet 52 is located at the lowest point of the shower head body 1. Specifically, the limiting seat 81 has a clearance opening 811 on the side facing the vent 51, so that only the side of the shower head body 1 with the vent 51 can tilt upward, while the side with the residual water drain outlet 52 can only tilt downward, thus ensuring that when the shower head body 1 deviates from the horizontal position, the residual water drain outlet 52 is located at the lowest point of the shower head body 1. In this way, water can flow out quickly from the residual water drain outlet 52.

[0049] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
