Description

Technical Field

[0001] The present invention relates to the field of faucets, and particularly to a waterway control component and a sensor faucet. Background Art

[0002] A sensor faucet controls the solenoid valve through a human body sensor to achieve the sensor control of water output or not, so that people can achieve the water output control without directly contacting the sensor faucet, which has the advantages of convenient use and hygiene.

[0003] In the existing sensor faucets, generally the solenoid valve is arranged in a sensor control box, and the sensor control box is independent of the faucet body of the sensor faucet. The sensor control box is installed under the table for use. Since the sensor control box is independent of the faucet body, after consumers purchase such a sensor faucet, they need to install the faucet body and the sensor control box by themselves. However, the space under the table is relatively narrow and the operation is inconvenient, which causes great inconvenience to consumers when installing the sensor control box.

[0004] Therefore, some people arrange the solenoid valve on the water outlet of the sensor faucet, which can facilitate consumers to install the sensor faucet. However, installing the solenoid valve on the water outlet will cause the water outlet to be very heavy. For a pull-out sensor faucet whose water outlet can be moved, when consumers move the water outlet, they need to drive the solenoid valve to move together, which causes consumers to spend a lot of effort when moving the water outlet, affecting the feeling of consumers when moving the water outlet and resulting in a poor user experience for consumers.

[0005] Based on the above defects, some people install the solenoid valve on the faucet body of the sensor faucet. In this way, after consumers purchase the sensor faucet, they do not need to install an additional sensor control box with a solenoid valve, and at the same time, they do not need to drive the solenoid valve to move together when moving the water outlet. However, there are also problems with the existing sensor faucets with the solenoid valve arranged on the faucet body. That is, the solenoid valve needs to be installed on the solenoid valve seat arranged in the faucet body, and the sensor faucet also needs to install the mixing valve core on the mixing valve seat arranged in the faucet body to adjust the water temperature of the water output. Among them, the mixing valve seat and the solenoid valve seat are independently arranged, so a complex waterway connection structure needs to be set between the solenoid valve seat and the mixing valve seat to connect, so as to enable the solenoid valve to control whether the water output of the mixing valve core can enter the water outlet and the external cold and hot water can be input into the mixing valve core. The assembly is relatively complex and cumbersome, resulting in low assembly efficiency of the sensor faucet. Summary of the Invention

[0067] As Figures 1 to 30 shown, the present invention discloses a waterway control component 1, which includes an integrated valve seat A and a solenoid valve B; wherein the integrated valve seat A is provided with a cold water inlet A1, a hot water inlet A2, a mixed water outlet A3, a water passing trough A4 and a mixed water valve core installation groove A5 for installing the mixed water valve core 2. The cold water inlet A1 and the hot water inlet A2 are communicated with the mixed water valve core installation groove A5. The water passing trough A4 is communicated with the mixed water valve core installation groove A5 through a water passing channel A6 arranged inside the integrated valve seat A. The mixed water outlet A3 is communicated with the water passing trough A4. The solenoid valve B is installed on the integrated valve seat A. The valve head B1 of the solenoid valve B extends into the water passing trough A4 and the valve head B1 of the solenoid valve B controls whether water flows out from the mixed water outlet A3.

[0068] In the waterway control assembly 1 of the present invention, the solenoid valve B is installed on the integrated valve seat A and controls whether water flows out of the mixing water outlet A3 of the integrated valve seat A.

The mixing valve core installation groove A5 is communicated with the cold water inlet A1, the hot water inlet A2 and the water passing groove A4, and the water passing groove A4 is communicated with the mixing water outlet A3. It can be seen from this that the integrated valve seat A of the present invention can integrally integrate the existing solenoid valve seat and the mixing valve seat and the waterway connection structure between the existing solenoid valve seat and the mixing valve seat. After the waterway control assembly 1 of the present invention is assembled, the solenoid valve B can be installed into the faucet body 3 of the induction faucet together with the integrated valve seat A, and there is no need to install the waterway connection structure between the existing solenoid valve seat and the mixing valve seat, thus simplifying the assembly process, improving the assembly efficiency of the induction faucet, and helping to simplify the structure of the induction faucet.

[0069] To facilitate the understanding of the waterway control assembly 1 of the present invention, the present invention will be described in detail below through two embodiments of the waterway control assembly 1.

[0070] The first embodiment of the waterway control assembly:

[0071] Cooperate Figures 1 to 11 As shown, in the first embodiment of the waterway control assembly 1 of the present invention, the openings of the cold water inlet A1 and the hot water inlet A2 of the integrated valve seat A can be both downward, and the opening of the mixing valve core installation groove A5 faces the side of the integrated valve seat A. The cold water inlet A1 and the hot water inlet A2 are respectively communicated with the mixing valve core installation groove A5 through the cold water channel A7 and the hot water channel A8 provided inside the integrated valve seat A; the opening of the water passing groove A4 is upward; the solenoid valve B is installed on the upper side of the integrated valve seat A. With such a setting of the present invention, the waterway control assembly 1 of the present invention can be applied to the faucet body 3 of the side-opening induction faucet, and the waterway control assembly 1 can be installed into the faucet body 3 from the installation pipe 32 on the side of the faucet body 3.

[0072] Cooperate Figure 1 And 2 As shown, in the first embodiment of the waterway control assembly 1 of the present invention, the opening of the mixing water outlet A5 is downward, so that the mixing water outlet A5 is suitable for connecting the water outlet pipe 4 that can be pulled and moved and the water outlet pipe 4 that does not need to be pulled and moved; the integrated valve seat A is also provided with a vertically penetrating pipe hole 19 for the water outlet pipe 4 to pass through. By providing the pipe hole 19, the present invention can provide a accommodating space for the water outlet pipe 4, so that the inner diameter of the main body 31 of the faucet body 3 can be made relatively small, which helps to reduce the size of the faucet body 3; in addition, the water outlet pipe 4 passing through the perforated hole A9 of the integrated valve seat A also helps to reduce the bending of the water outlet pipe 4, so that the water outlet pipe 4 can be smoothly pulled.

[0073] CooperateFigure 7 and Figure 8 As shown in Figure 8 , in the first embodiment of the waterway control component 1 of the present invention, an opening and closing port A41 communicating with the mixed water outlet A3 is provided at the bottom of the water passing tank A4; the valve head B1 of the solenoid valve B movably blocks the opening and closing port A41 to control whether water flows out of the mixed water outlet A3; the opening and closing port A41 and the mixed water outlet A3 can communicate vertically; the solenoid valve B is controlled by a control signal to control the movement of the valve head B1, so that the valve head B1 opens or blocks the opening and closing port A41.

[0074] cooperate Figure 7 and Figure 8 As shown in Figure 8 , in the first embodiment of the waterway control component 1 of the present invention, the solenoid valve B can block the opening of the water passing tank A4. The solenoid valve B is provided with a partition B2 that divides the internal space of the water passing tank A4 into a water flow chamber A401 and an air flow chamber A402. The water flow chamber A401 communicates with the valve core installation groove A5 through a water passing channel A6. The water flow chamber A401 also communicates with the mixed water outlet A3 through the opening and closing port A41. The air inlet and outlet hole B3 of the solenoid valve B is located in the air flow chamber A402 and the air inlet and outlet hole B3 of the solenoid valve B communicates with the air flow chamber A402. The air inlet and outlet of the air inlet and outlet hole B3 of the solenoid valve B enables the valve head B1 of the solenoid valve B to move. The valve head B1 of the solenoid valve B extends into the water flow chamber A401 to control whether water flows out of the mixed water outlet A3; the integrated valve seat A is provided with an air flow channel A10 that communicates the air flow chamber A402 and the mixed water outlet A3. The present invention enables the air inlet and outlet hole B3 to communicate with the outside by setting the air flow channel A10, ensuring that the valve head B1 can move; the air flow channel A10 communicates the air flow chamber A402 and the mixed water outlet A3. In this way, if there is a problem with the seal between the water flow chamber A401 and the air flow chamber A402 and the water in the water flow chamber A401 flows into the air flow chamber A402, the water entering the air flow chamber A402 will also flow to the mixed water outlet A3 through the air flow channel A10, thereby preventing water from overflowing everywhere; the integrated valve seat A is also provided with a core-pulling port A11 that communicates with the air flow channel A10. The core-pulling port A11 is blocked by a sealing plug C to prevent the air flow channel A10 from leaking water; the present invention enables the integrated valve seat A to be formed by injection molding and facilitates the formation of the air flow channel A10 by setting the core-pulling port A11; similarly, the integrated valve seat A may also be provided with a core-pulling hole A12 that communicates with the water passing channel A6. The core-pulling hole A12 is blocked by a core-pulling plug D to prevent the water passing channel A6 from leaking water; the present invention sets the core-pulling hole A12 to enable the integrated valve seat A to be injection molded and facilitates the formation of the water passing channel A6.

[0075] cooperate Figure 3 、 Figure 5 and Figure 8As shown, in the first embodiment of the waterway control component 1 of the present invention, the integrated valve seat A is further provided with a buffer channel A13. The inner end of the buffer channel A13 communicates with the water passing channel A6, the outer end of the buffer channel A13 communicates with the outside, and a buffer component E is fitted in the buffer channel A13. When the solenoid valve B shuts off the water flow at the mixed water outlet A3, at this time, the buffer component E can absorb the energy of the water flow in the water passing channel A6 to reduce the impact of the water flow on the integrated valve seat A and the solenoid valve B, thereby reducing the vibration and noise generated by the waterway control component 1 and achieving the effect of preventing water hammer. The buffer component E includes a buffer block E1 and a buffer spring E2. The buffer block E1 is movably accommodated in the buffer channel A13. The buffer block E1 is movably and sealingly fitted with the buffer channel A13 to prevent water leakage from the buffer channel A13. One end of the buffer spring E2 extends into the buffer channel A13, and the end of the buffer spring E2 abuts against one side of the buffer block E1 away from the inner end of the buffer channel A13. The other end of the buffer spring E3 abuts against the faucet body C after the waterway control component 1 is installed in the faucet body C. When the solenoid valve B shuts off the water flow at the mixed water outlet A3, the buffer block E1 will move towards the outer end of the buffer channel A13 under the action of the water flow, thereby compressing the buffer spring E2 and absorbing the energy of the water flow.

[0077] Cooperate Figures 12 to 22 As shown, in the second embodiment of the waterway control component 1 of the present invention, the difference between the second embodiment of the waterway control component 1 and the first embodiment of the waterway control component 1 lies in the setting of the mixed water outlet A3. Specifically, in the second embodiment of the waterway control component 1 of the present invention, the opening of the mixed water outlet A3 is arranged upward, and the mixed water outlet A3 is suitable for connecting a water outlet pipe 4 that does not need to be pulled and moved. Since the water outlet pipe 4 does not need to be pulled and moved, the integrated valve seat A does not need to be provided with a pipe passing hole A9.
