Description

Technical Field

[0001] This invention relates to the field of smart toilet technology, specifically to a water storage control valve. Background Technology

[0002] A control valve is a switch valve used to control the on / off state of a water circuit. It is typically connected to the tap water supply and is widely used in the direct-flush valve flushing system of smart toilets. Compared to flushing systems with a water tank, direct-flush valve flushing systems have advantages such as lower cost, lower power consumption, smaller size, and easier control. However, when smart toilets need to be equipped with other devices such as foam shields, atomizing devices, and electrolyzed water devices, existing control valves cannot meet the water supply requirements of these devices, thus limiting their application.

[0003] Therefore, this application studies a water storage control valve, which can increase the application scenarios of the control valve and meet multifunctional needs. Utility Model Content

[0004] To expand the application scenarios of control valves and meet multifunctional needs, this application provides a water storage control valve.

[0005] This application provides a water storage control valve, which adopts the following technical solution:

[0006] A water storage control valve includes a valve body, which has an inlet channel, an outlet channel, and a water-stopping part for controlling the opening and closing of the inlet channel and the outlet channel. The outlet channel is connected to a toilet bowl. The valve body also includes a small water tank with a water storage chamber connected to the outlet channel. When the water-stopping part opens the inlet channel to allow water to enter, at least a portion of the water can be stored in the water storage chamber. The small water tank is also connected to an external device and supplies water to the external device.

[0007] By adopting the above technical solution, external devices such as foam shield devices, atomizing devices, and electrolyzed water devices can be provided with a stable water source by setting up a small water tank. This solves the problem that existing control valves cannot supply water to these devices. Without affecting the normal operation of the control valve flushing system, the water intake is rationally distributed. Part of the water enters the toilet bowl for flushing, while the other part is stored in the small water tank to supply water to other devices, thereby meeting the needs of multiple functions of the smart toilet and increasing the application scenarios of the control valve.

[0008] Optionally, the small water tank is provided with an interface for communication with external devices.

[0009] Optionally, the interface is provided with a normally open one-way valve. When the small water tank supplies water to the external device, the normally open one-way valve opens the interface; when the control valve is opened, it supplies water to the water storage chamber, and the normally open one-way valve closes the interface.

[0010] By adopting the above technical solution, the normally open check valve ensures that water will not be discharged in large quantities from the interface when the control valve is opened.

[0011] Optionally, a filter is connected to the end of the interface facing into the small water tank.

[0012] By adopting the above technical solution, impurities can be effectively prevented from entering the mixing chamber, reducing system failures caused by impurity blockage.

[0014] Optionally, the valve body is provided with an inner water outlet pipe and an outer water outlet pipe. The inner water outlet pipe is provided with a first water outlet channel. The outer water outlet pipe is connected to the water outlet end of the inner water outlet pipe. The outer water outlet pipe is provided with a sleeve portion sleeved outside the inner water outlet pipe and an extension portion extending radially outward along the sleeve portion. The extension portion is provided with a socket that is inserted into the insertion portion. The insertion portion is provided with an inlet and an outlet that are connected to the water storage chamber. A partition is provided axially inside the extension portion. The partition is located between the inlet and the outlet, thereby dividing the outer water outlet pipe into a second water outlet channel and a third water outlet channel.

[0015] Optionally, the external device is a foam shield device, which includes a mixing chamber and a raw liquid chamber. The mixing chamber is connected to the interface, and the raw liquid chamber is used to store foam raw liquid. During operation, the small water tank supplies water to the mixing chamber, and the raw liquid chamber supplies raw liquid to the mixing chamber.

[0016] By adopting the above technical solution, the small water tank directly supplies water to the mixing chamber of the foam shield device through the interface, ensuring that the foam shield device can obtain a stable water source when it is working.

[0017] Optionally, the foam shield device further includes a water pump, which connects the water storage chamber and the mixing chamber. During operation, the water pump draws water from the water storage chamber into the mixing chamber; the water pump is a diaphragm pump.

[0018] Optionally, the foam shield device further includes a foam nozzle, which includes a liquid inlet, a foam outlet, and an air intake channel.

The brush ring channel is connected to the water outlet channel, and the foam outlet channel is connected to the foam outlet. Alternatively, the brush ring nozzle has a brush ring channel, which is connected to the water outlet channel and the foam outlet channel.

[0019] By adopting the above technical solution, when the foam shield device is working, water is drawn from the water storage tank to dilute the original liquid in the original liquid chamber to generate foam.

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a water storage control valve. (Refer to...) Figures 1-3 The water storage control valve includes a valve body 1, which has an inlet channel 2 and an outlet channel 3, as well as a water-stopping part that controls the opening and closing of the inlet channel 2 and the outlet channel 1. The inlet channel 2 is covered with an inlet cap 4, and the water-stopping part has a water-stopping pad 5. When the control valve is opened, the water-stopping pad 5 opens under the action of water flow. The outlet channel 3 is connected to the toilet bowl, and one end of the outlet channel 3 is provided with an anti-siphon plug 6. At the same time, a pressure cap 7 and an upper cover 8 are snapped into place at the end. It also includes a small water tank 9, which has a water storage chamber 10, which is connected to the outlet channel 3. When the water-stopping part opens the inlet channel 2 to allow water to enter, the water flows from the inlet channel 2 into the outlet channel 3 and pushes open the anti-siphon plug 6. At least part of the water can be stored in the water storage chamber 10, that is, some water or all water can be stored in the water storage chamber 10.

[0036] The small water tank 9 is also connected to external devices and supplies water to them. These external devices include the foam shield device 14, the atomizing device, and the electrolyzed water device. This provides a stable water source for these devices, solving the problem that existing control valves cannot supply water to them. Without affecting the normal operation of the direct flush valve flushing system, it achieves a reasonable distribution of the incoming water. Part of the water enters the toilet bowl for flushing, while the other part is stored in the small water tank 9 to supply water to other devices, thus meeting the needs of multiple functions of the smart toilet and increasing the application scenarios of the control valve.

[0037] In some embodiments, the small water tank 9 is provided with an interface 11, which connects to external devices, making it easy to connect to external devices.

[0038] In some embodiments, a normally open check valve 12 is provided at the interface 11. When the small water tank 9 supplies water to external devices, the normally open check valve 12 opens the interface 11; when the control valve is opened, it supplies water to the water storage chamber 10, and the normally open check valve 12 closes the interface.

[0039] In some embodiments, a filter 13 is connected to the end of the interface 11 facing into the small water tank 9. The filter 13 can better filter the water quality and reduce the possibility of clogging by external equipment.

[0040] In some embodiments, the small water tank 9 is provided with a plug-in part 22, and the small water tank 9 is plugged into the water outlet channel 3 of the valve body 1 through the plug-in part 22; the water outlet channel 3 includes a first water outlet channel 31, a second water outlet channel 32 and a third water outlet channel 33, the first water outlet channel 31 is sleeved in the second water outlet channel 32 and is respectively connected to the water inlet channel 2 and the second water outlet channel 32, the water outlet end of the second water outlet channel 32 is connected to the inlet of the water storage chamber 10, the third water outlet channel 33 is arranged in parallel with the second water outlet channel 32, and the water inlet end of the third water outlet channel 33 is connected to the outlet of the water storage chamber 10.

[0041] In some embodiments, the valve body 1 is provided with an inner water outlet pipe 23 and an outer water outlet pipe 24. The inner water outlet pipe 23 is provided with a first water outlet channel 31. The outer water outlet pipe 24 is connected to the water outlet end of the inner water outlet pipe 23. The outer water outlet pipe 24 is provided with a sleeve portion 25 sleeved outside the inner water outlet pipe 23 and an extension portion 26 extending radially outward along the sleeve portion 25. The extension portion 26 is provided with a socket that is inserted into the insertion portion 22. The insertion portion 22 is provided with an inlet and an outlet connected to the water storage chamber 10. A partition 27 is provided axially inside the extension portion 26. The partition 27 is located between the inlet and the outlet, thereby dividing the outer water outlet pipe 24 into a second water outlet channel 32 and a third water outlet channel 33.

[0042] Reference Figure 4 In some embodiments, the external device is a foam shield device 14, which includes a mixing chamber 15 and a raw liquid chamber 16. The mixing chamber 15 is connected to the interface 11, and the raw liquid chamber 16 is used to store foam raw liquid. During operation, the small water tank 9 supplies water to the mixing chamber 15, and the raw liquid chamber 16 supplies raw liquid to the mixing chamber 15.

[0043] In some embodiments, the foam shield device 14 further includes a water pump 17, which connects the water storage chamber 10 and the mixing chamber 15. During operation, the water pump 17 draws water from the water storage chamber 10 into the mixing chamber 15. The water pump 17 is a diaphragm pump. In other embodiments, when using a diaphragm pump, the normally open check valve 12 may not be used, which can still prevent a large amount of water from being discharged from the interface.

[0044] Reference Figure 3 and Figure 4 In some embodiments, the foam shield device 14 further includes a foam nozzle 18, which includes a liquid inlet, a foam outlet, and an air intake channel. The liquid inlet is connected to a mixing chamber 15, and the mixture in the mixing chamber 15 can enter the foam nozzle 18 through the liquid inlet to form foam and then flow to the foam outlet. It also includes a brush ring nozzle 19, which has a brush ring channel 21 and a foam outlet channel 20. The brush ring channel 21 is connected to a water outlet channel 3, and the foam outlet channel 20 is connected to the foam outlet. Alternatively, the brush ring nozzle 19 has a brush ring channel 21, which is connected to the water outlet channel 3 and the foam outlet.

[0045] In some embodiments, the control valve is any one of a solenoid valve, a reversing valve, a mechanical switching valve, or a back pressure inlet valve, and the control valve is connected to the municipal water supply.

[0046] When the flushing procedure is executed and the control valve coil is activated, the water-stop pad 5 opens under the action of water flow. The water flows into the outlet channel 3, pushes open the anti-siphon plug 6, and enters the water storage chamber 10 of the small water tank 9. Then, it is sprayed out through the brush ring channel 21 of the brush ring nozzle 19 to flush the toilet bowl. The normally open one-way valve 12 on the small water tank 9 can close the outlet connected to the foam shield device 14 under the action of water pressure. Of course, the normally open one-way valve 12 can also be omitted here. The water pump 17 in the foam shield device 14 can also prevent a large amount of water from overflowing. A small portion of the overflowing water can return to the toilet bowl through the foam channel 20 after passing through the foam shield device 14 and the foam nozzle 18. After the flushing procedure is completed, the water storage chamber 10 in the small water tank 9 stores water, which can provide a water source for the foam shield to work.

[0047] Reference Figure 5When stationary, the normally open one-way valve 12 is open, and the water storage chamber 10 is connected to the foam shield device 14. When the normally open one-way valve 12 is not installed, the water storage chamber 10 is always connected to the foam shield device 14. When the foam shield device 14 is working, it can draw water from the water storage chamber 10 to dilute the foaming agent and finally generate foam. The generated foam is discharged from the foam outlet channel 20 and then flows into the toilet water cover to form a foam shield.

[0048] Reference Figure 2 , Figure 3 and Figure 6 When the foam shield device 14 is working, the water pump 17 starts, drawing water from the water storage chamber 10 to generate foam; when the water pump 17 stops, the foam shield device 14 stops working. Before the water pump 17 stops, the control valve can be opened to replenish water to the water storage chamber 10 in the small water tank 9 and to expel the air accumulated in the water storage chamber 10 due to the water being drawn out. During this process, no large water pressure will form in the small water tank 9, thus ensuring that the normally open one-way valve 12 remains open. After the foaming is finished, the control valve remains open, and after the water flow fills the water storage chamber 10, flushing water can be sprayed out from the brush ring channel 21 of the brush ring nozzle 19 to pre-wet the toilet bowl surface.

[0049] By opening the control valve to replenish water before the foaming process ends, it is possible to ensure a stable discharge rate and no exhaust noise during the subsequent flushing process. At the same time, it can also store water for the next use of the foam shield function.

[0050] The implementation principle of a water storage control valve in this application embodiment is as follows: external devices include foam shield device 14, atomizing device, electrolytic water device, etc. By setting a small water tank 9, a stable water source can be provided for the external devices, solving the problem that existing control valves cannot supply water to these devices. Without affecting the normal operation of the control valve flushing system, the water intake is reasonably distributed. Part of the water enters the toilet bowl for flushing, and the other part of the water is stored in the small water tank 9 to supply water to other devices, thereby meeting the needs of multiple functions of the smart toilet and increasing the application scenarios of the control valve.
