[0002] Most water circuit switching valves currently on the market achieve water circuit switching by setting multiple valves or complex mechanical structures. This design not only has high production costs, but is also prone to failure. Utility Model Content

[0003] The purpose of this utility model is to provide a water path switching structure, and the technical problem to be solved is to achieve water output switching between two water outlet paths through a simple structure.

[0004] To achieve the above objectives, the solution of this utility model is: a water circuit switching structure, including a first water circuit, a second water circuit, a switching valve, and a water stop assembly;

[0005] The inlet ends of the first and second waterways are connected;

[0006] The switch valve is located in the first water passage and is used to open or close the water passage.

[0007] The water-stopping assembly includes a pressure chamber and a water-stopping element. The pressure chamber has an installation port, and the water-stopping element is installed on the installation port. The pressure chamber is connected to the first water passage, and the connection point is located downstream of the switch valve. The outlet end of the second water passage is located on the side of the water-stopping element facing away from the pressure chamber and towards the water-stopping element. The water-stopping element is displaced or deformed under the water pressure of the pressure chamber and the outlet end of the second water passage, so that when the switch valve opens the first water passage, the water pressure in the pressure chamber pushes to block the outlet end of the second water passage, and when the switch valve blocks the first water passage, the water pressure at the outlet end of the second water passage pushes to open the outlet end of the second water passage.

[0008] Furthermore, the water outlet cross-section of the first water outlet is smaller than the water outlet cross-section of the second water outlet.

[0009] Furthermore, the outlet of the first water path is used to connect to an aerator, and the outlet of the second water path is used to connect to a shower head or a faucet outlet.

[0010] Furthermore, the water-stopping element is made of a deformable flexible material and is used to seal the installation port of the pressure chamber.

[0011] Furthermore, an elastic element is provided inside the pressure chamber. The elastic element elastically pushes against the water-stopping element in the direction of the outlet end of the second water channel, so as to press the water-stopping element onto the outlet end of the second water channel.

[0012] Furthermore, the water-stopping element is made of a deformable flexible material, and there is a disc-shaped part between the elastic element and the water-stopping element. The disc-shaped part is rigid and is located on the side of the water-stopping element facing the pressure chamber, directly opposite the water outlet end of the second water channel, and its area is larger than the cross-section of the water outlet end of the second water channel.

[0013] Furthermore, the water-stopping component is provided with a guide core, which extends into the second water channel when the water-stopping component blocks the outlet end of the second water channel.

[0014] Furthermore, the pressure chamber is formed on the side wall of the first waterway to communicate with the first waterway at the side wall of the first waterway.

[0015] Furthermore, a water outlet cavity is formed around the water outlet end of the second water channel so that the water discharged from the water outlet end of the second water channel flows into the water outlet cavity, and the water outlet cavity forms a water outlet for discharging the water flow in the water outlet cavity.

[0016] After adopting the above solution, the beneficial effects of this utility model are as follows: the inlet ends of the first water passage and the second water passage are connected, the switch valve is set in the first water passage for opening or blocking the water flow of the first water passage, the pressure chamber of the water-stopping component has an installation port, the water-stopping element is set on the installation port, the pressure chamber is connected to the first water passage, the connection point is located downstream of the switch valve, the outlet end of the second water passage is located on the side of the water-stopping element facing away from the pressure chamber, facing the water-stopping element, the water-stopping element is displaced or deformed under the water pressure of the pressure chamber and the outlet end of the second water passage, so that when the switch valve opens the first water passage, the outlet end of the second water passage is blocked under the push of the water pressure in the pressure chamber, and when the switch valve blocks the first water passage, the outlet end of the second water passage is opened under the push of the water pressure at the outlet end of the second water passage, thereby controlling the water flow switching of the two water passages through a switch valve. The structure is very simple, and the water flow switching of the two water passages is realized through a simple structure. Attached Figure Description

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] The embodiments of the present invention will be fully described below with reference to the accompanying drawings. It should be noted that the present invention may be implemented in different forms and is not limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the present invention to those skilled in the art.

[0024] A waterway switching structure, such as Figure 1-4 As shown, the system includes a first water passage 1, a second water passage 2, a switch valve 3, and a water-stopping assembly 4. The inlet ends of the first water passage 1 and the second water passage 2 are connected to a water source device, such as a household water pipe network. The switch valve 3 can be any existing water circuit switch valve, which can be manual or electric, without specific limitations. The switch valve 3 is located in the first water passage 1 and is used to open or close the flow of water through the first water passage 1. Of course, it can be understood that "located in the first water passage 1" here necessarily means that it is located downstream of the connection between the first water passage 1 and the second water passage 2, without affecting the second water passage 2. The water-stopping assembly 4 includes a pressure chamber 5 and a water-stopping element 6. The pressure chamber 5 has an installation port 7, and the water-stopping element 6 is installed on the installation port 7. The pressure chamber 5 is connected to the first water passage 1, and the connection point is located downstream of the switch valve 3. The outlet end of the second water passage 2 is located on the side of the water-stopping element 6 that faces away from the pressure chamber 5 and towards the water-stopping element 6. The water-stopping element 6 is under pressure. The pressure at the outlet of the first water passage 1 and the pressure chamber 5 causes the water to shift or deform. When the switch valve 3 opens the first water passage 1, the water flow from the first water passage 1 enters the pressure chamber 5, increasing the water pressure inside the pressure chamber 5. This causes the water stop 6 to overcome the reverse pushing force generated by the water flow inside the outlet of the second water passage 2. Under the pressure of the water in the pressure chamber 5, the water stop 6 is pressed against the outlet of the second water passage 2, sealing the outlet of the second water passage 2. At this time, the water supplied by the water source device will only be discharged from the outlet of the first water passage 1. When the switch valve 3 seals the first water passage 1, the water pressure in the pressure chamber 5 decreases. Under the pressure of the water at the outlet of the second water passage 2, the water stop 6 shifts in the direction away from the outlet of the second water passage 2, opening the outlet of the second water passage 2. At this time, the water supplied by the water source device will only be discharged from the outlet of the second water passage. This achieves the switching of water flow between two water passages by controlling one switch valve 3, resulting in a relatively simple structure.

[0025] In a preferred embodiment, the water outlet cross-section of the first water path 1 is smaller than that of the second water path 2. On the one hand, this can provide greater water pressure to the pressure chamber 5 when the switch valve 3 is opened. On the other hand, it is to meet the following application scenarios: that is, the water outlet of the first water path 1 can flow out a smaller flow to connect to an aerator, and the water outlet of the second water path 2 can flow out a larger flow to connect to a shower head or faucet outlet.

[0026] Specifically, in this embodiment, the water-stopping element 6 is made of a deformable flexible material and is sealed on the mounting port 7 of the pressure chamber 5. Under the drive of water pressure, it deforms toward the inside of the pressure chamber 5 to open the outlet of the second water passage 2, or deforms toward the outside of the pressure chamber 5 to block the outlet of the second water passage 2.

[0027] To ensure that the water-stopping element 6 can press with sufficient pressure on the outlet end of the second water passage 2, preferably in this embodiment, an elastic element 10 is provided in the pressure chamber 5. The elastic element 10 elastically pushes the water-stopping element 6 towards the outlet end of the second water passage 2 to press the water-stopping element 6 on the outlet end of the second water passage 2. More specifically in this embodiment, the elastic element 10 is a compression spring.

[0028] The water-stopping element 6 is provided with a guide core 8. When the water-stopping element 6 blocks the outlet end of the second water passage 2, the guide core 8 extends into the second water passage 2 to play a guiding role. The guide core 8 is connected to a disc-shaped part 11 on the side facing the pressure chamber 5. The disc-shaped part 11 is made of rigid material and is located on the side of the water-stopping element 6 facing the pressure chamber 5, directly opposite the outlet end of the second water passage 2, and its area is larger than the cross-section of the outlet end of the second water passage 2. The elastic element 10 acts on the disc-shaped part 11 to more effectively seal the outlet end of the second water passage 2.

[0029] For structural simplicity, the pressure chamber 5 is formed on the waterway sidewall of the first waterway 1 to communicate with the first waterway 1 at the waterway sidewall of the first waterway 1.

[0030] In order to facilitate the collection and supply of water discharged from the outlet of the second water passage 2 to the water-using device, it is preferable to form an outlet cavity 9 around the outlet of the second water passage 2 so that the water discharged from the outlet of the second water passage 2 flows into the outlet cavity 9. The outlet cavity 9 forms an outlet for discharging the water in the outlet cavity 9.

[0031] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
