Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, specifically to a diversion valve core and a shower with residual water drainage function. Background Technology

[0002] In existing faucets, residual water remains in the internal flow channel or on the water outlet components connected to the faucet, such as the shower head or overhead spray, after the valve core is closed. Because this residual water is not drained, problems such as dripping and scaling can easily occur. In cold environments, it can even freeze, preventing the valve core from opening. Therefore, more and more bathroom products are incorporating residual water drainage mechanisms to expel residual water after the valve core is closed. For example, Chinese patent CN208221624U discloses an antifreeze faucet that can drain residual water. This involves installing a drain device on the faucet body, which, when pressed after the valve core is closed, drains the water remaining inside the faucet. However, in practice, the user must first close the valve core and then operate the drain device to expel the residual water, which is cumbersome and inconvenient for users. Furthermore, if the user forgets to press the drain device after closing the valve core, the residual water remains inside the faucet, meaning that in this type of structure, residual water cannot be automatically drained. Utility Model Content

[0003] This utility model discloses a diversion valve core, which aims to improve the problems of existing residual water discharge structures being inconvenient for user operation and unable to discharge automatically.

[0004] The present invention adopts the following solution:

[0005] A diversion valve core includes a valve stem, a housing, and a movable plate and a stationary plate disposed within the housing. The valve stem is linked to the movable plate to drive the movable plate to move and / or rotate. The movable plate has a water passage groove, and the stationary plate has an inlet for communicating with an inlet channel, an outlet for communicating with an outlet channel, and a drain outlet for communicating with a drain channel. When the inlet is connected to the outlet via the water passage groove, the valve core is in an open state; when the outlet is connected to the drain outlet via the water passage groove, the valve core is in a closed state.

[0006] As a further improvement, the bottom surface of the housing is provided with an inlet hole communicating with the inlet and an outlet hole communicating with the outlet, and the side surface of the housing is provided with a drain hole communicating with the drain outlet.

[0007] As a further improvement, the housing is provided with a drainage channel extending in an L-shape, the inlet end of the drainage channel is aligned with the drain outlet, and the drain hole is formed at the outlet end of the drainage channel.

[0008] As a further improvement, the water outlet is located in the middle of the stationary plate, and the drain outlet and the water inlet are respectively located on both sides of the water outlet.

[0009] As a further improvement, the valve stem is hinged to the housing, and the moving plate moves relative to the stationary plate by driving the valve stem to swing.

[0010] As a further improvement, a pressure cap is provided on the top of the housing, and the valve stem is connected to the pressure cap via a pin.

[0011] As a further improvement, the gland is detachably connected to the housing.

[0012] As a further improvement, the housing is provided with a transmission plate, a moving plate, a stationary plate and a sealing element arranged sequentially from top to bottom. The transmission plate is provided with a drive groove and a first limiting part. One end of the valve stem is inserted into the drive groove. The moving plate is provided with a second limiting part for engaging and limiting with the first limiting part. One side of the stationary plate is in contact with the moving plate and the other side abuts against the sealing element, so that the water inlet and the water inlet hole, the water outlet and the water outlet hole and the water outlet hole are connected in a one-to-one correspondence.

[0013] As a further improvement, the bottom surface of the housing is provided with a positioning post, which is used to fit into the positioning hole in the valve cavity so as to limit the valve core.

[0014] Another showerhead with residual water drainage function is provided, including a shower faucet and a top spray. The shower faucet is provided with a valve chamber, a water inlet channel, a water outlet channel and a drain channel. The valve chamber is provided with a diverter valve core as described in any of the above claims. The water inlet channel is connected to the water inlet. The water inlet end of the water outlet channel is connected to the water outlet. The drain channel is connected to the drain outlet. The top spray is connected to the water outlet end of the water outlet channel.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] 1. This application connects the drain port and the outlet port while the valve core is closed, allowing residual water in the outlet channel to be automatically discharged through the drain port. This allows the user to complete both shutting off the water flow and draining residual water with a single operation, making it convenient and ensuring that residual water is automatically discharged after each water flow shutdown.

[0017] 2. The drainage holes are located on the side of the shell, which is conducive to the setting of drainage channels and avoids the problem of complex and intersecting channels that are not convenient for mold opening, as all channels are set on the bottom surface of the shell.

[0018] 3. The outlet is located in the middle of the stationary plate, while the drain and inlet are located on either side of the outlet. This reduces the movement distance of the moving plate when switching between open and closed states, saving space in the housing and allowing the valve core to be made smaller to accommodate more faucets.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0035] Combination Figures 1 to 6 This embodiment provides a diversion valve core, including a valve stem 1, a housing 2, and a moving plate 3 and a stationary plate 4 disposed within the housing 2. The valve stem 1 and the moving plate 3 are linked to drive the moving plate 3 to move and / or rotate. The moving plate 3 is provided with a water passage groove 31, and the stationary plate 4 is provided with an inlet 41 for communicating with the inlet channel, an outlet 42 for communicating with the outlet channel, and a drain 43 for communicating with the outlet channel. When the inlet 41 is connected to the outlet 42 through the water passage groove 31, the valve core is in the open state; when the outlet 42 is connected to the drain 43 through the water passage groove 31, the valve core is in the closed state. Specifically, when the valve core is open, water flows from the inlet channel into the inlet 41 and then from the outlet 42 to the outlet channel, at which time the drain 43 is isolated from the outlet 42. When the valve core is closed, the outlet 42 is isolated from the inlet 41 and connected to the drain outlet 43 through the water tank 31, so that the water remaining in the outlet channel can flow from the drain outlet 43 to the drain channel.

[0036] It should be noted that in this embodiment, while the valve core is closed, the drain port 43 is connected to the outlet port 42, so that the residual water in the outlet channel can be automatically discharged from the drain channel through the drain port 43. The user only needs one operation to complete the shutdown of the water flow and the discharge of residual water, which is convenient for the user and ensures that the residual water is automatically discharged after each shutdown of the water flow.

[0037] In a preferred embodiment, the bottom surface of the housing 2 is provided with an inlet hole 21 communicating with the inlet 41 and an outlet hole 22 communicating with the outlet 42, and the side surface of the housing 2 is provided with a drain hole 23 communicating with the outlet 43. The location of the drain hole 23 on the side surface of the housing 2 facilitates the arrangement of drainage channels, avoiding the problem of complex and intersecting channels that would hinder mold making if all channels were located on the bottom surface of the housing 2. In an optional embodiment, the housing 2 is provided with a drainage channel 24 extending in an L-shape, the inlet end of which is aligned with the outlet 43, and the drain hole 23 is formed at the outlet end of the drainage channel 24. The L-shaped extension facilitates mold making, allowing the housing 2 to be integrally molded, reducing the number of parts and saving costs.

[0038] In another embodiment, the outlet 42 is located in the middle of the stationary plate 4, and the drain outlet 43 and the inlet 41 are respectively located on both sides of the outlet 42. The valve stem 1 is hinged to the housing 2, and the moving plate 3 moves relative to the stationary plate 4 by driving the valve stem 1 to swing. Setting the outlet 42 in the middle of the stationary plate 4 can reduce the movement distance of the moving plate 3 when switching between the open and closed states, which helps to save space in the housing 2, so that the valve core can be made smaller to accommodate more faucets.

[0039] For example, a pressure cap 5 is disposed on the top of the housing 2, and the valve stem 1 is connected to the pressure cap 5 via a pin 6 so that the valve stem 1 can swing. Preferably, the pressure cap 5 and the housing 2 are detachably connected, which can be a snap-fit ​​connection or other connection methods in the prior art, so as to facilitate the disassembly and assembly of the valve core.

[0040] Based on the above embodiments, in an optional embodiment of the present invention, the housing 2 is provided with a transmission plate 7, a moving plate 3, a stationary plate 4 and a sealing member 8 arranged sequentially from top to bottom. The transmission plate 7 is provided with a drive groove 71 and a first limiting part 72. One end of the valve stem 1 is inserted into the drive groove 71. The moving plate 3 is provided with a second limiting part 32 for engaging and limiting with the first limiting part 72. One side of the stationary plate 4 is in contact with the moving plate 3, and the other side abuts against the sealing member 8, so that the water inlet 41 is connected to the water inlet hole 21, the water outlet 42 is connected to the water outlet hole 22, and the drain outlet 43 is connected to the drain hole 23 in a one-to-one correspondence. For example, when valve stem 1 is upright, the valve core is in the closed state. At this time, the water channel 31 is connected to the drain port 43 and the outlet port 42, and the water flows from the outlet port 42 to the drain port 43. When valve stem 1 is moved, the moving plate 3 moves, and the water channel 31 is connected to the inlet port 41 and the outlet port 42, and the water flows from the inlet port 41 to the outlet port 42. The moving plate 3 and the stationary plate 4 are preferably made of ceramic.

[0041] Preferably, the bottom surface of the housing 2 is provided with a positioning post 25, which is used to fit with the positioning hole in the valve cavity to limit the valve core. During installation, the positioning post 25 is inserted into the positioning hole to align the water inlet hole 21 with the water inlet channel, the water outlet hole 22 with the water outlet channel, and the drain hole 23 with the drain channel, ensuring the accurate position of the valve core.

[0042] This utility model also provides a shower with a residual water drainage function, including a shower faucet and a top spray. The shower faucet has a valve chamber, a water inlet channel, a water outlet channel, and a drain channel. The valve chamber is equipped with a diverter valve core as described in any of the previous embodiments. The water inlet channel is connected to the water inlet 41, the water inlet end of the water outlet channel is connected to the water outlet 42, the drain channel is connected to the drain outlet 43, and the top spray is connected to the water outlet end of the water outlet channel. When the valve core is open, water flows from the water inlet channel to the top spray. When the valve core is closed, residual water in the top spray and the water outlet channel flows out through the drain channel.

[0043] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
