[0007] A multifunctional valve structure, comprising a valve body internally formed with a water passing cavity, the upper and lower ends of the water passing cavity are respectively formed with a water outlet and a water inlet filter hole penetrating the cavity wall, water flows from the outside of the water inlet filter hole into the water passing cavity and then flows out from the water outlet, which is forward water inlet, and vice versa, which is reverse water inlet; the lower end of the water passing cavity is connected with a sealing structure, which has a first working state of being separated from the water inlet filter hole under the action of water pressure when the water inlet is forward, and a second working state of completely covering and sealing the water inlet filter hole under the action of water pressure when the water inlet is reverse.

[0008] Further, the sealing structure is a cavity type sealing sheet matched with the cavity structure of the lower end of the water passing cavity, which completely covers the water inlet filter hole.

[0027] Valve body 1, water passage chamber 10, water outlet 101, water inlet filter hole 102, chamber bottom 103, chamber wall 104, connecting hole 105, extension part 11, main body part 12; sealing structure 2, bottom 21, cone part 22, connector 23; plug 3, threaded structure 31, inner seal 41, upper seal 42, lower seal 43; shower faucet 200, hot water circuit 201. Detailed Implementation

[0028] The following detailed description of this case is provided in conjunction with the accompanying drawings and specific embodiments.

[0029] This case involves a multifunctional valve structure, such as Figures 1-3 As shown, the valve body 1 includes a water passage cavity 10 inside. The upper and lower ends of the water passage cavity 10 are respectively formed with an outlet 101 and an inlet filter hole 102, both penetrating the cavity wall. In practice, several outlets 101 are arranged in a circular pattern, and multiple inlet filter holes 102 are arranged evenly. Water flows from the outside of the inlet filter hole 102 into the water passage cavity 10 and then out through the outlet 101, which is the forward water inlet direction of the multi-functional valve structure; the reverse direction is the reverse water inlet direction.

[0030] The lower end of the water passage cavity 10 is connected to a sealing structure 2. The sealing structure 2 has a first working state in which it is separated from the water inlet filter hole 102 under the action of water pressure when water enters in the forward direction, and a second working state in which it completely covers and seals the water inlet filter hole 102 under the action of water pressure when water enters in the reverse direction.

[0031] When water flows in the forward direction, that is, when water flows from the outside through the inlet filter hole 102 into the water passage chamber 10, the sealing structure 2 is in the first working state. At this time, the sealing structure 2 separates from the inlet filter hole 102 under the action of water pressure. The water flows around the sealing structure 2 and smoothly enters the water passage chamber 10, and then flows out from the upper outlet 101, realizing the functions of normal water output and water filtration and purification.

[0032] When the water flows in the opposite direction, that is, the water flows from the outside of the outlet 101 into the water passage 10, the sealing structure 2 completely covers and seals the inlet filter hole 102 under the action of water pressure. The inlet filter hole 102 is closed, which prevents the water from flowing outward from the inlet filter hole 102, thereby realizing the one-way backflow prevention function.

[0033] like Figures 4-5 As shown, this novel multi-functional valve structure is mainly applied to the shower faucet 200. In one specific embodiment, the novel multi-functional valve structure is installed on the hot water circuit 201 of the shower faucet 200. Of course, it can also be installed on other water circuits of the shower faucet 200 as needed. It can simultaneously achieve two functions: one-way backflow prevention and water filtration. Compared with the prior art, this novel structure is more integrated, has a simplified structure, is easier to install, and has a lower cost.

[0034] In this embodiment, as Figure 2 As shown, the sealing structure 2 is a cavity-shaped sealing sheet that matches the cavity structure at the lower end of the water passage cavity 10, and the cavity-shaped sealing sheet completely covers the water inlet filter hole 102. The structural design of the cavity-shaped sealing sheet facilitates the formation of the first working state and the second working state.

[0035] Further as Figure 3 As shown, the lower end of the water passage cavity 10 has a cavity bottom 103 and a cavity wall 104 forming an inverted conical structure with the cavity bottom 103. The water inlet filter hole 102 is formed on the cavity wall 104. The cavity-shaped sealing sheet has a bottom 21 and a conical portion 22 that match the cavity structure. The bottom 21 is connected to the cavity bottom 103. The cavity structure and the cavity-shaped sealing sheet have the inverted conical structure. The cavity bottom 103 and the bottom 21 cooperate to facilitate connection. The water inlet filter hole 102 is formed on the cavity wall 104, which is inclined on the side. This facilitates the cavity-shaped sealing sheet and the water inlet filter hole 102 to cooperate to switch freely between the first working state and the second working state.

[0036] like Figure 3 As shown, a connecting hole 105 is formed on the bottom 103 of the cavity, and a connector 23 is formed on the bottom 21 of the cavity-shaped sealing sheet, which penetrates the connecting hole 105. By assembling the connector 23 with the connecting hole 105, the cavity-shaped sealing sheet can be stably set at the lower end of the water passage cavity 10, and at the same time, it can achieve two stable and reliable working states.

[0037] As Figure 2 shown, the valve body 1 is divided into the main body part 12 formed with the water inlet filter hole 102 and the extension part 11 located at the upper end of the main body part 12 and formed with the water outlet 101, and the inner cavity of the extension part 11 forms a water passing buffer area. The valve body 1 adopts the structure of the combination of the main body part 12 and the extension part 11, which is beneficial to the assembly and replacement of the sealing structure 2 in the main body part 12 on the one hand, and on the other hand, when the water flow is reversed, the water potential energy is appropriately accumulated in the water passing buffer area, which ensures that the sealing structure 2 can tightly cover and seal the water inlet filter hole 102, and realizes the stable and reliable one-way non-reversing effect.

[0038] In the embodiment, the multifunctional valve structure further comprises a plug 3 located at the upper end of the valve body 1, and the plug 3 is formed with a connecting structure. When the multifunctional valve structure is applied, the plug 3 and the connecting structure are used to realize the overall detachable installation of the multifunctional valve structure.

[0039] Therefore, the plug 3 is designed to make the multifunctional valve structure into an integrated detachable structure. In use, the entire multifunctional valve structure is disassembled for operation, which is convenient for cleaning and replacing the sealing structure 2, and has excellent practical performance.

[0040] In the specific embodiment, the connecting structure is a threaded structure 31 formed on the plug 3.

[0041] As Figures 1-3 shown, the plug 3 and the valve body 1 are provided with an inner sealing element 41, so that the plug 3 and the valve body 1 avoid rigid contact and play a sealing role between them. The plug 3 is provided with an upper sealing element 42, which is convenient for sealing installation of the plug 3.

[0042] In addition, the valve body 1 is formed with a lower sealing element 43 located between the water outlet 101 and the water inlet filter hole 102, so that after the valve body 1 is assembled, the lower sealing element 43 realizes the water sealing between the water outlet 101 and the water inlet filter hole 102.

[0043] As Figure 1 shown, the plug 3 is provided with a one-word tool slot, which is convenient for embedding a one-word screwdriver to realize simple disassembly and assembly of the plug 3. Of course, the one-word tool slot can also be changed into a cross-shaped slot or other arbitrary shape slot.

[0044] The above is only the preferred embodiment of the present application, and any equivalent changes and modifications made within the scope of the claims of the present application shall belong to the scope of the claims of the present application.
