Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to an intelligent toilet and its pump flushing tank system. Background Technology

[0002] A smart toilet is an automated sanitary ware that integrates multiple advanced technologies and user-friendly designs, providing users with a more convenient, comfortable, and hygienic experience.

[0003] After a smart toilet finishes flushing, it typically refills the toilet bowl with water to form a water seal at the bottom, blocking the sewage pipe inlet and preventing odors from entering the room and polluting the indoor air. However, existing water seals have a small water flow rate, resulting in a long refilling time and an inability to form a water seal in time. Consequently, the sewage pipe inlet cannot be sealed in time, allowing odors from the sewage pipe to still enter the room before the water seal is formed.

[0004] In addition, most smart toilets draw water from the tank to power the flush, so the tank needs to hold enough water, resulting in a large capacity and high cost. Utility Model Content

[0005] To address the aforementioned problems, this invention provides an intelligent toilet and its pump-flush tank system, which can promptly form a water seal to block the inlet of the sewage pipe, thereby preventing odors from entering the room.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] This utility model provides a pump-flushing water tank system, including a water tank, an inlet valve, a water pump, and a control valve; the inlet valve includes a valve head, an inlet channel for water intake, and a first outlet and a second outlet respectively connected to the inlet channel; the inlet of the control valve is connected to the first outlet, and the outlet of the control valve is connected to the upper flushing outlet; the valve head is used to control the opening and closing of the second outlet, and the second outlet is connected to the inlet of the water tank for replenishing the water tank; the water pump is installed in the water tank for pumping water from the water tank, and the outlet of the water pump is connected to the lower flushing outlet.

[0008] Furthermore, the control valve is a DC valve or a pulse valve.

[0009] Furthermore, the inlet valve also includes a valve body, a float tank disposed on the valve body, a float movably disposed within the float tank, and a lifting rod rotatably connected to the valve body; the valve body has the inlet channel, the first outlet, and the second outlet, and the valve head is assembled at the second outlet; one end of the lifting rod is connected to the float, and the other end is used to control the valve head to open and close the second outlet; the valve body and the float tank are arranged vertically, and the float tank extends into the water tank; the float tank has a drain hole for draining water and is equipped with a float plug, which is used to control the opening and closing of the drain hole.

[0010] Furthermore, the float tank has a drainage cavity for connecting the water tank on the bottom wall away from the float, and the drainage cavity has a drain hole near the upper wall of the float. The float plug is movably assembled in the drainage cavity, and the sealing surface of the float plug corresponds to the drain hole.

[0011] Furthermore, the inner wall of the water tank is provided with a support boss for supporting the float tank.

[0012] Furthermore, the water pump is equipped with a connecting pipe at its outlet, and the outlet end of the connecting pipe extends out of the water tank to connect to the lower flush outlet.

[0013] Furthermore, the water tank is provided with a drain switch for draining water on the side wall at its bottom.

[0014] This utility model provides an intelligent toilet, which includes at least the pump flushing tank system described above.

[0015] The technical solution provided by this utility model has the following beneficial effects:

[0016] In use, the control valve is first activated, causing water in the inlet channel to flow out through the control valve and then through the upper flush outlet to the upper flush head of the smart toilet, thereby flushing the toilet bowl walls for several seconds. Then, the water pump is activated to draw water from the tank and then through the lower flush outlet to the lower flush head of the smart toilet, thereby spraying the bottom of the toilet bowl. At this time, the control valve is still working, ensuring that the upper and lower flushes work simultaneously.

[0017] Even after the water pump stops working, the control valve continues to operate to ensure that the single operating time of the control valve is greater than that of the water pump. This allows for timely replenishment of the water seal in the toilet bowl, with a sufficiently large replenishment volume, and timely sealing of the sewage pipe inlet, thereby preventing foul odors from the sewage pipe from entering the room.

[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] Reference Figures 1 to 5 As shown, Embodiment 1 provides a pump-flush tank system for use with a smart toilet to flush its toilet bowl, and includes a water tank 1, an inlet valve 2, a water pump 3, and a control valve 4.

[0027] like Figure 4 and Figure 5 As shown, the water inlet valve 2 includes a valve head 21, a water inlet channel 22 for water inlet, and a first outlet and a second outlet respectively connected to the water inlet channel 22. The water inlet of the water inlet channel 22 is connected to an external water source (or water supply pipe).

[0028] like Figure 1 and Figure 2 As shown, the inlet of control valve 4 is connected to the first outlet of inlet valve 2, and the outlet of control valve 4 is used to connect to the flush outlet of the smart toilet.

[0029] The valve head 21 is used to control the opening and closing of the second outlet of the inlet valve 2. The second outlet of the inlet valve 2 is connected to the inlet of the water tank 1 to supply water to the water tank 1.

[0030] The water pump 3 is installed inside the water tank 1 to draw water from the water tank 1, and the outlet of the water pump 3 is connected to the flush outlet of the smart toilet.

[0031] In this embodiment, the control valve 4 is a DC valve. Of course, in other embodiments, the control valve 4 can also be a pulse valve.

[0032] like Figure 2 and Figure 3 As shown, the outlet of the water pump 3 is equipped with a connecting pipe 31, and the outlet end of the connecting pipe 31 extends out of the water tank 1 to connect to the lower flush outlet.

[0033] In use, first drive the control valve 4 to work, so that the water in the water inlet channel 22 flows out through the control valve 4, and then flows out through the upper flush outlet to the upper flush head of the smart toilet, thereby achieving an upper flushing and brushing of the toilet bowl wall for several seconds. Then drive the water pump 3 to draw water from the water tank 1, and then flow out through the lower flush outlet to the lower flush head of the smart toilet, so as to achieve a spraying of the bottom of the toilet bowl. At this time, the control valve 4 is still working, ensuring that the upper and lower flushes are performed simultaneously.

[0034] When water pump 3 stops working, control valve 4 continues to work to ensure that the single working time of control valve 4 is greater than the single working time of water pump 3. This allows for timely replenishment of the water seal in the toilet bowl, with a sufficient amount of water replenishment, and timely sealing of the sewage pipe inlet, thereby preventing odors from the sewage pipe from entering the room.

[0035] In another preferred embodiment, such as Figure 4 and Figure 5 As shown, the inlet valve 2 also includes a valve body 23, a float tank 24 disposed on the valve body 23, a float 25 movably disposed in the float tank 24, and a lifting rod 26 rotatably connected to the valve body 23.

[0036] More specifically, the valve body 23 and the float tank 24 are arranged vertically, and the valve body 23 has a water inlet channel 22, a first water outlet and a second water outlet. The valve head 21 is assembled at the second water outlet of the valve body 23 to control the opening and closing of the second water outlet of the valve body 23.

[0037] The left end of the lifting rod 26 is fixedly connected to the float 25, and the other right end is used to control the valve head 21 to open or close the second outlet. That is, the float 25 rises or falls in the float tank 24 due to the change in the amount of water loaded, so as to drive the lifting rod 26 to swing within a certain rotation angle range. In this way, the valve head 4 can be opened or closed respectively, thereby controlling the water to flow out or close the second outlet.

[0038] The float tank 24 extends into the water tank 1. The float tank 24 has a drain hole 241 for drainage and is equipped with a float plug 242, which is used to control the opening and closing of the drain hole 241.

[0039] In this specific embodiment, such as Figure 5 As shown, the bottom wall of the float tank 24 away from the float 25 has a drainage chamber 243 for connecting the water tank 1. The drainage chamber 243 is provided with a drain hole 241 near the upper wall of the float 25. At this time, the two ends of the drain hole 241 are connected to the water tank 1 and the drainage chamber 243 respectively.

[0040] The float plug 242 is movably assembled in the drain cavity 243, and the sealing surface of the float plug 242 corresponds to the drain hole 241.

[0041] After the water in the water tank 1 is pumped away by the water pump 3 and used for flushing the toilet, the water in the float tank 24 is also discharged into the water tank 1 through the drain hole 241. As a result, the water level in the float tank 24 continues to drop, and the float 25 floating in the float tank 24 also falls down. The float 25 drives the lifting rod 26 to fall down and opens the valve head 21 to ensure that water can flow out of the second outlet, thereby replenishing the water tank 1 until the water level in the water tank 1 exceeds the upper opening of the float tank 24. At this time, water will flow into the float tank 24 to increase the water level in the float tank 24. At the same time, the float 25 also rises up. The float 25 drives the lifting rod 26 to rise until the valve head 21 is closed, thereby stopping the second outlet from continuing to flow out water. At the same time, the water tank 1 is also filled with water. Furthermore, during the process of replenishing water tank 1, the float plug 242, which is submerged in water, rises in the drain chamber 243 due to buoyancy until the sealing surface of the float plug 242 is pressed against the lower opening of the drain hole 241, thereby sealing the drain hole 241.

[0042] When the water in the water tank 1 is pumped out until it can no longer contact the float 242, the float 242 falls due to loss of buoyancy and moves away from the drain hole 241, at which point the drain hole 241 is opened.

[0043] In addition, the triggering time of valve head 21 depends on the lifting speed of lifting rod 26, the lifting speed of lifting rod 26 depends on the falling speed of float 25, the falling speed of float 25 depends on the outflow speed of water in float tank 24, and the outflow speed of water in float tank 24 depends on the inner diameter of drain hole 241.

[0044] In this embodiment, the inner diameter of the preset drain hole 241 is small enough to ensure that the falling speed of the float 25 and the lifting speed of the lifting rod 26 are slow enough, so that the valve head 21 will not be triggered to open immediately or in a short time. This ensures that when the control valve 4 is opened, the valve head 21 is in the closed state, that is, only the first outlet is water, while the second outlet is in the closed state. Therefore, at this time, the control valve 4 and the valve head 21 are not open or in the water outlet state at the same time, thereby ensuring that the water pressure supplied by the external water source can still meet the flushing water pressure requirements of the smart toilet even under the premise of low pressure.

[0045] Further preferred, such as Figure 2 As shown, the inner wall of the water tank 1 is provided with a support boss 11 for supporting the float tank 24.

[0046] Further preferred, such as Figure 2 As shown, a drain switch 12 for draining water is provided on the side wall at the bottom of the water tank 1.

[0047] The pump flushing tank system of this embodiment needs to be tested for qualification before leaving the factory. Therefore, the water tank 1 will be filled with water for testing. After the test is qualified, the drain valve 12 needs to be opened before packaging to ensure that the water injected into the water tank 1 during the test is drained.

[0048] In addition, when the water inlet valve of this embodiment is connected to the tap water source provided by the municipal water supply system, the water replenishment and adjustment mechanism is jointly formed by the float tank 24, float 25, lifting rod 26 and valve head 21. The water replenishment and adjustment mechanism, control valve 4 and water pump 3 are coordinated and operated through the main control system of the smart toilet to realize that the flushing and down flushing actions of the smart toilet are executed synchronously within a period of time. This ensures that the smart toilet of this embodiment is quieter when flushing the toilet bowl.

[0049] Furthermore, since the flushing water of the smart toilet in this embodiment comes directly from the tap water source delivered by the control valve 4, it is no longer necessary to draw water from the water tank 1. Therefore, it is no longer necessary to increase the volume of the water tank 1. Instead, the volume of the water tank 1 can be further reduced to facilitate the miniaturization of the water tank 1, thereby reducing the manufacturing cost of the entire pump flushing water tank system.
