Description

Technical Field

[0001] This utility model belongs to the field of home bathroom technology, specifically relating to a dual-control solenoid valve squat toilet sensor flushing mechanism. Background Technology

[0002] Squat toilets are simple in structure, inexpensive, convenient and hygienic to use, and account for as much as 70% of bathroom fixtures. Existing squat toilets typically include a toilet bowl, a drain pipe, and a water inlet. One end of the drain pipe connects to the bottom of the toilet bowl, forming a water trap (water seal), and the other end of the drain pipe has a drain outlet.

[0003] Currently, squat toilets typically have only one water inlet, and the surface of the squat toilet sensor bowl is covered with water outlets. By using a large volume of water and a certain flushing force, waste is flushed down. However, if the water pressure is too low, it will be difficult to flush the waste. This places high demands on the water supply pressure and the design of the squat toilet's flushing structure, and the phenomenon of difficulty in flushing waste often occurs.

[0004] Some toilets have a main nozzle on the side wall furthest from the trap, and an auxiliary nozzle on the side wall closest to the trap. Because the inlet and auxiliary nozzle are located on the same side of the toilet, the connecting pipe between the auxiliary nozzle and the inlet is shorter than that between the main nozzle and the inlet. Therefore, when flushing, the auxiliary nozzle often sprays water before the main nozzle. However, since the main nozzle hasn't started spraying yet, some of the waste on the toilet bowl hasn't reached the trap. This results in some of the water sprayed from the auxiliary nozzle being wasted, leading to insufficient flushing power and affecting the flushing effect. Therefore, users often have to flush a second time for a more thorough flush, resulting in water waste. Utility Model Content

[0005] The purpose of this invention is to provide a dual-control solenoid valve squat toilet flushing mechanism to solve the aforementioned technical problems in the prior art.

[0006] Therefore, the technical solution provided by this utility model is as follows:

[0007] A dual-control solenoid valve squat toilet flushing mechanism includes a main water supply pipeline, a controller, a human body sensor and a dual-control solenoid valve. The human body sensor and the dual-control solenoid valve are both electrically connected to the controller. The main water supply pipeline and the water inlet of the dual-control solenoid valve are connected.

[0008] The dual-control solenoid valve includes a first solenoid valve and a second solenoid valve. The water outlet of the first solenoid valve is connected to the water outlet on the upper ring surface of the squat toilet through a first water outlet pipe, and the water outlet of the second solenoid valve is connected to the bottom flushing port of the water seal vortex surface of the squat toilet through a second water outlet pipe.

[0009] Furthermore, a connecting mechanism is provided between the first solenoid valve and the second solenoid valve, and the connecting mechanism is connected to the main water supply pipeline.

[0010] Furthermore, the human body sensor is used to sense signals and send signals to the controller, and the controller is used to send a command to control the dual-control solenoid valve to open after receiving the signal from the human body sensor.

[0011] Furthermore, the dual-control solenoid valve is equipped with an air isolation valve, which is located at the top of the communication mechanism.

[0012] Furthermore, a built-in water circuit switch valve is provided between the connecting mechanism and the main water supply pipeline. The built-in water circuit switch valve is equipped with a removable filter screen and is electrically connected to the controller.

[0013] Furthermore, the human body sensing device is an infrared sensor, a hand switch, or a foot switch.

[0014] Furthermore, the main water supply pipeline is a water supply pipe with a diameter greater than 6 points.

[0015] Furthermore, the power supply for this induction flushing mechanism is either DC power from a battery box or AC-to-DC power.

[0016] The beneficial effects of this utility model are as follows:

[0017] The dual-control solenoid valve squat toilet flushing mechanism provided by this utility model divides the single large water path of the squat toilet into two separate sequential water supply methods through dual solenoid valves. The first water path can concentrate water force to flush the toilet's fall point, allowing the waste to be discharged to the water seal. Then, the bottom jet force of the water seal is used to further discharge the waste, similar to the main sewage pipe, making the sewage discharge force more concentrated.

[0018] This dual-control solenoid valve squat toilet flushing mechanism controls the entire sewage discharge process through a human body sensor. The controller controls the opening sequence of the dual-control solenoid valves to achieve sewage discharge. The dual-control solenoid valve is equipped with an air isolation valve to prevent sewage from flowing back into the water supply pipe when there is negative pressure in the pipeline. The built-in water circuit switch valve has a removable filter screen for easy cleaning and to prevent the dual-control solenoid valve from being blocked by foreign objects in the water.

[0028] Example 1

[0029] This embodiment provides a dual-control solenoid valve squat toilet sensor flushing mechanism, such as... Figure 1 As shown, it includes a main water supply pipeline 1, a controller, a human body sensor 10, and a dual-control solenoid valve. The human body sensor 10 and the dual-control solenoid valve are both electrically connected to the controller, and the main water supply pipeline 1 and the water inlet of the dual-control solenoid valve are connected.

[0030] The dual-control solenoid valve includes a first solenoid valve 4 and a second solenoid valve 5. The water outlet of the first solenoid valve 4 is connected to the water outlet 6 on the upper ring surface of the squat toilet through a first water outlet pipe 12. The water outlet of the second solenoid valve 5 is connected to the bottom flushing port 7 of the water seal vortex 9 of the squat toilet 14 through a second water outlet pipe 13.

[0031] like Figure 1 and Figure 3As shown, the water outlet 6 on the upper ring of the squat toilet and the main sewage pipe 16 are located at the same end of the squat toilet 14, and the water seal vortex 9 is located at the other end of the squat toilet 14. The water seal vortex 9 and the main sewage pipe 16 are connected by a water seal pipe, and the second water outlet pipe 13 is connected to the water seal pipe. The water seal vortex 9 is as follows... Figure 4 As shown.

[0032] Working principle:

[0033] After the user finishes using the toilet, the human body sensor 10 receives the human body signal and sends a signal to the controller. The controller sends a command to open the first solenoid valve 4 of the dual-control solenoid valve. Water is discharged through the main water supply pipe 1, the inlet pipe 15, the first outlet pipe 12, and the outlet 6 on the upper surface of the squat toilet, directly pushing the waste on the toilet's upper surface 8 to the water seal vortex 9 of the squat toilet 14. Then, the controller sends a command to open the second solenoid valve 5 of the dual-control solenoid valve. Water is sprayed out through the second outlet pipe 13 and the flushing port 7 at the bottom of the water seal vortex 9 of the squat toilet 14. The spray force pushes the waste from the water seal vortex 9 of the squat toilet 14 to the main sewage pipe 16.

[0034] After the sewage discharge is completed, the controller sends a command to open the first solenoid valve 4 of the dual-control solenoid valve again. Water enters the water seal vortex 9 of the squat toilet 14 through the main water supply pipeline 1, the inlet pipeline 15, the first outlet pipeline 12, and the outlet 6 on the upper ring of the squat toilet, to replenish the water seal of the squat toilet and block the odor from the pipe.

[0035] The entire sewage discharge process is initiated by the human body sensor 10, and the sewage discharge process is controlled by the sewage discharge program built into the controller. The sewage discharge program is existing technology.

[0036] Example 2

[0037] Based on Embodiment 1, this embodiment provides a dual-control solenoid valve squat toilet sensor flushing mechanism, wherein a connecting mechanism 3 is provided between the first solenoid valve 4 and the second solenoid valve 5, and the connecting mechanism 3 is connected to the main water supply pipeline 1.

[0038] like Figure 2 As shown, the first solenoid valve 4 and the second solenoid valve 5 are connected to the main water supply pipeline 1 through a connecting structure.

[0039] Example 3

[0040] Based on Embodiment 1, this embodiment provides a dual-control solenoid valve squat toilet sensor flushing mechanism. The human body sensor 10 is used to sense signals and send signals to the controller. The controller is used to send a command to control the dual-control solenoid valve to open after receiving the signal from the human body sensor 10.

[0041] The sewage discharge process is triggered by the human body sensor 10 receiving a human body signal. The controller can be a micro switch with chip-programmed control or a PLC controller.

[0042] Example 4

[0043] Based on Embodiment 2, this embodiment provides a dual-control solenoid valve squat toilet sensor flushing mechanism, wherein the dual-control solenoid valve is provided with an air isolation valve 11, which is located at the top of the connecting mechanism 3.

[0044] like Figure 2 As shown, the dual-control solenoid valve is equipped with an air isolation valve 11 to prevent sewage from flowing back into the water supply pipe when there is negative pressure in the pipeline.

[0045] Example 5

[0046] Based on Embodiment 2, this embodiment provides a dual-control solenoid valve squat toilet sensor flushing mechanism. A built-in water circuit switch valve 2 is provided between the connecting mechanism 3 and the main water supply pipeline 1. A removable filter screen is provided inside the built-in water circuit switch valve 2. The built-in water circuit switch valve 2 is electrically connected to the controller.

[0047] The built-in water circuit switch valve 2 has a removable filter screen for easy cleaning and to prevent the dual-control solenoid valve from being blocked by foreign objects in the water.

[0048] The human body sensor 10 triggers the sewage discharge program to start. First, the controller controls the built-in water circuit switch valve 2 to open, and then controls the first solenoid valve 4 and the second solenoid valve 5 to start. After the squat toilet water seal is replenished, the controller controls the built-in water circuit switch valve 2 to close.

[0049] Example 6

[0050] Based on Embodiment 1, this embodiment provides a dual-control solenoid valve squat toilet sensor flushing mechanism, wherein the human body sensor 10 is an infrared sensor, a hand switch, or a foot switch.

[0051] This embodiment uses an infrared sensor as an example, which has a built-in infrared emitter and receiver. When a person enters the infrared area near the squat toilet 14, the infrared light emitted by the emitter is reflected back to the receiver after being blocked by the person. After receiving the reflected signal, the receiver transmits it to the controller for processing. After analyzing the signal, the controller sends a command to the dual-control solenoid valve. After receiving the signal, the dual-control solenoid valve dispenses water according to the specified command.

[0052] The principles of manual switches and foot switches are similar. They both transmit signals to the controller, which then controls the opening and closing of the dual-control solenoid valve.

[0053] Example 7

[0054] Based on Embodiment 1, this embodiment provides a dual-control solenoid valve squat toilet sensor flushing mechanism, wherein the main water supply pipeline 1 is a water supply pipe with a diameter greater than 6 points.

[0055] The main water supply pipe 1 has an inner diameter greater than 6 points (approximately 0.6 mm) to ensure sufficient water volume and pressure while minimizing water loss. The power supply for this sensor-activated flushing mechanism is either DC power from a battery box or AC-to-DC power.

[0056] In summary, this utility model, through dual-control solenoid valves, can concentrate the flushing force of the toilet bowl. By opening the first solenoid valve, the waste from the toilet bowl 14 is directly discharged to the water seal vortex 9. Then, by opening the second solenoid valve 5, all the flushing force is concentrated at the spray point to discharge the waste into the main sewage pipe 16, which saves water pressure and solves the problem of water pressure consumption when the original single solenoid valve controls water output, flushing and sewage discharge at the same time.

[0057] The examples above are merely illustrative of utility models and do not constitute a limitation on the scope of protection of utility models. All designs that are the same as or similar to utility models fall within the scope of protection of utility models.
