Description

Technical Field

[0001] The utility model relates to the application field of faucets, and specifically relates to a solenoid valve for a dual-control faucet. Background Art

[0002] With the rapid development of artificial intelligence and human-computer interaction modes, consumers have higher and higher requirements for kitchen and bathroom products. Especially, the demand for intelligent kitchen products is gradually increasing; higher requirements are also put forward for intelligent control, water conservation and environmental protection, convenience and hygiene, and simple installation and maintenance. Similar products have developed rapidly in the domestic and international markets in recent years. However, most of the kitchen faucets on the market are single manual control or single automatic control faucets, and do not realize the function of a faucet having both manual and automatic functions at the same time. The market has a strong demand for kitchen faucets with integrated manual and automatic intelligent control. For example, there are differences in the water temperature of manual water outlet and automatic water outlet during use, which is easier to meet different usage requirements of water temperature. However, one of the difficulties of manual and automatic integrated faucets is that when the manual switch is turned on, it is easy to accidentally trigger the automatic induction switch, and water will also flow out from the automatic induction pipeline. If the automatic water outlet pipeline and the manual water outlet pipeline flow out water at the same time, it is not easy to control the water temperature and it is difficult to meet the usage requirements. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a solenoid valve for a dual-control faucet that has both automatic and manual water outlet functions and the automatic water outlet pipeline will not flow out water after the induction switch is triggered when the manual water outlet pipeline is in the water outlet state.

[0004] The technical solution adopted by the utility model to solve the above problems is as follows: A solenoid valve for a dual-control faucet includes a water flow channel. An automatic water inlet channel connected to an automatic water inlet pipe and a manual water inlet channel connected to a manual water inlet pipe are provided on the side of the water flow channel. One end of the water flow channel is provided with a water outlet. A water flow sensor trigger end is arranged inside the manual water inlet channel, a water flow sensor receiving end is arranged outside the manual water inlet channel, a water flow sensor execution end is arranged at the end of the water flow channel far from the water outlet. The water flow sensor receiving end is electrically connected to the water flow sensor execution end, and the water flow sensor execution end is electrically connected to a switch on the automatic water inlet pipe to control the water inlet of the automatic water inlet pipe.

[0005] Compared with the prior art, the utility model has the following advantages: the water outlet flow channel is connected to the automatic water inlet pipe and the manual water inlet pipe at the same time, the automatic water inlet pipe is opened and closed by sensing the hand under the faucet, and the manual water inlet pipe is manually opened and closed by a traditional switch, so that the faucet has both automatic water outlet function and manual water outlet function, and meets the different usage requirements of customers, and through the design of the water flow sensor trigger end, the water flow sensor receiving end and the water flow sensor execution end, the automatic water inlet pipe can be prevented from filling with water during the manual water inlet process, thereby avoiding the mixing of manual water inlet and automatic water inlet with temperature difference, resulting in uncontrollable water outlet temperature at the water outlet, because during the manual water inlet process, the hand will also move in the sensing area below the faucet. If the water inlet function of the automatic water inlet pipe is not prevented, the automatic water inlet pipe will easily be continuously sensed and opened and closed.

[0006] As an improvement of the utility model, the trigger end of the water flow sensor is a magnetic impeller, the magnetic impeller is a magnetic part, the receiving end of the water flow sensor includes a Hall element, and the Hall element is embedded in an installation groove. Through the improvement, the stability and timeliness of the Hall element's sensing of the magnetic impeller are guaranteed.

[0007] As an improvement of the utility model, the end of the manual water inlet channel away from the water outlet channel and the water outlet are both provided with a water pipe plug-in structure, and the water pipe plug-in structure includes a connecting expansion. Through the improvement, it is convenient to achieve the docking of the manual water inlet pipe with the manual water inlet channel and to achieve the docking of the water outlet pipe with the water outlet. The other end of the water outlet pipe is connected to the faucet, and through the design of the connecting expansion, the inner diameter of the manual water inlet pipe can be close to the inner diameter of the manual water inlet channel, and the inner diameter of the water outlet pipe can be close to the inner diameter of the water outlet, which is not easy to cause turbulence.

[0008] As an improvement of the present invention, a button sheet is provided on the connecting flare, and locking holes are provided on two opposite sides of the connecting flare. The button sheet is embedded in the locking hole on one side and passes through the locking hole on the other side. A through hole for the water supply pipe to pass through is provided in the center of the button sheet, and an elastic member is provided between the button sheet and the outer side of the connecting flare. Through the improvement, through the design of the button sheet and the elastic member, the manual water inlet pipe can be offset and stuck after the manual water inlet pipe is inserted into the connecting flare to achieve the purpose of fixing the manual water inlet pipe, and the water outlet pipe can be offset and stuck after the water outlet pipe is inserted into the water outlet to achieve the purpose of fixing the water outlet pipe.

[0009] As an improvement of the present utility model, the elastic member is a spring piece, and an inclined block for elastically abutting against the spring piece is provided on the outer side of the connecting flared opening. Through the above improvement, the elastic function of the elastic member is realized. When the button piece is pressed, the spring piece abuts against the inclined block and deforms, and the axis of the through hole moves axially towards the axial direction of the connecting flared opening to unlock the water pipe, facilitating the insertion and extraction of the water pipe. After the button piece is released, the spring piece resets to fix the water pipe. The design of the inclined block is to adapt to the deformation amplitude of each area of the spring piece to ensure the deformation effect of the spring piece.

[0010] As an improvement of the present utility model, a limit seat for limiting the moving direction of the button piece is provided on the outer side of the connecting flared opening to ensure the stability of the abutting force direction between the spring piece and the inclined block. Through the above improvement, not only can the moving direction of the button piece be limited to ensure the stability of the abutting force direction between the spring piece and the inclined block and avoid rotation, but also the elastic abutting fit between the spring piece and the inclined block can be protected, preventing impurities from entering between the elastic member and the inclined block and affecting the comfort of pressing the button piece.

[0011] As an improvement of the present utility model, an external thread for threaded connection with the automatic water inlet pipe is provided at one end of the automatic water inlet flow channel far from the water outlet pipe. Through the above improvement, different from the water outlet and the manual water inlet flow channel, since the automatic water inlet flow channel is also connected to the electric control switch, an external thread structure is adopted for threaded connection with the electric control switch.

[0019] The embodiments of the present utility model will be further described below with reference to the accompanying drawings.

[0020] As Figure 1-2 shown, a solenoid valve for a dual-control faucet includes an outlet water flow channel 1. An automatic inlet water flow channel 2 communicating with an automatic water inlet pipe and a manual inlet water flow channel 3 communicating with a manual water inlet pipe are provided on the side of the outlet water flow channel 1. An outlet 1.1 is provided at one end of the outlet water flow channel 1. A water flow sensor trigger end 4 is provided inside the manual inlet water flow channel 3. A water flow sensor receiving end is provided outside the manual inlet water flow channel 3. A water flow sensor execution end 5 is provided at the end of the outlet water flow channel 1 away from the outlet. The water flow sensor receiving end is electrically connected to the water flow sensor execution end 5 through a single-chip microcomputer control system. The water flow sensor execution end 5 is electrically connected to a switch on the automatic water inlet pipe to control the water inlet of the automatic water inlet pipe. An external thread 2.1 for threaded connection with an electric control switch is provided at the end of the automatic inlet water flow channel 2 away from the outlet pipe.

[0021] As Figure 1-5 shown, a water pipe plugging structure is provided at the end of the manual inlet water flow channel 3 away from the outlet water flow channel 1 and at the outlet 1.1. The water pipe plugging structure includes a connecting flare 6. A button piece 7 is provided on the connecting flare 6. Locking holes 6.1 are provided on opposite sides of the connecting flare 6. The button piece 7 is inserted into the locking hole 6.1 on one side and passes through the locking hole 6.1 on the other side. A through hole 7.1 for the water pipe to pass through is provided at the center of the button piece 7. A spring piece 7.2 is provided between the outer side of the button piece 7 and the connecting flare 6. An inclined block 6.2 for elastically abutting against the spring piece 7.2 is provided on the outer side of the connecting flare 6. A limit seat 6.3 for limiting the moving direction of the button piece 7 is provided on the outer side of the connecting flare 6 to ensure the stability of the abutting force direction between the spring piece 7.2 and the inclined block 6.2.

[0022] When the connecting flare 6 is not inserted into the water pipe, the button piece 7 is separated from the locking hole 6.1. When the water pipe needs to be inserted, the button piece 7 needs to be passed through the two locking holes 6.1 first, and the spring piece 7.2 is pressed to make the axis of the through hole 7.1 approach or coincide with the axis of the connecting flare 6, and then the water pipe is inserted. Then the button piece 7 is released. Under the action of the spring piece 7.2 and the inclined block 6.2, the spring piece 7.2 resets, and the axis of the through hole 7.1 is separated from the axis of the connecting flare 6 to lock the water pipe.

[0023] The trigger end 4 of the water flow sensor is a magnetic impeller with magnets. The magnetic impeller is a magnetic component. The receiving end of the water flow sensor includes a Hall element. The Hall element is embedded in an installation groove 8. The execution end 5 of the water flow sensor is a switch controller. During the rotation of the magnetic impeller with magnets, the magnetic field of the Hall element will change, so as to achieve the signal for prompting water to flow into the manual water inlet channel 3. Then the Hall element feeds back the signal to the single-chip microcomputer control system. The single-chip microcomputer control system processes the signal and sends an execution signal to the execution end 5 of the water flow sensor to close the electric control switch, so as to prevent water from flowing into the automatic water inlet pipe. The sensing effect between the magnetic impeller with magnets and the Hall element, as well as the signal conversion and transmission of the single-chip microcomputer control system, belong to conventional technologies and are widely used in water heaters in daily life.

[0024] During use, if only high-temperature water needs to be discharged, the manual water inlet pipe can be closed, and the automatic water inlet pipe is always kept in the inductive opening state. When the inductive area below the faucet receives a signal, the automatic water inlet pipe will have a short automatic water discharge. When low-temperature water needs to be discharged, the manual water inlet pipe can be directly opened. When water flows through the magnetic impeller with magnets in the manual water inlet channel 3, the magnetic impeller with magnets will rotate, and then the execution end 5 of the water flow sensor closes the automatic water inlet pipe. Then when flushing in the inductive area below the faucet, the water temperature will not be too high or too low or the overall water temperature will not be too high, and the consistency between the discharged water temperature and the required water temperature can be maintained.

[0025] As Figure 6 As shown in the figure, a rubber film 9 is provided at the connection between the automatic water inlet channel 2 and the water outlet channel 1. When there is no water flowing through the automatic water inlet channel 2, the rubber film 9 abuts against the water outlet channel 1 to close the water outlet channel 1. When water enters the automatic water inlet channel 2, the water pressure will push up the rubber film 9 to connect the automatic water inlet channel 2 and the water outlet channel 1. At the same time, the rubber film 9 can also play a good role in buffering the water hammer of the automatic water inlet channel 2.

[0026] The above is only an illustration of the best embodiment of the present invention, but it should not be construed as a limitation of the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to change. All changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
