Abstract
Description
Technical Field
[0001] This utility model relates to the field of toilet technology, specifically to an integrated water pump device and a toilet made of it. Background Technology
[0002] Toilets are an indispensable facility in every household. Toilets are generally divided into squat toilets or sit-down toilets. Different toilets are selected and installed according to different family needs. The drain outlet at the bottom of the toilet is connected to the sewer pipe. The inside of the toilet has a curved flow channel connected to the drain outlet. The upper edge of the toilet cavity has a ring-shaped flushing water channel. After the excrement is discharged, the curved flow channel will also store water for liquid seal to prevent odors from the sewer pipe from spreading out through the curved flow channel.
[0003] Currently, toilets have a flushing water path and a flushing drainage path inside. The flushing water path washes away debris from the inner wall of the toilet to the bottom, while the flushing drainage path uses a larger volume of water to carry the excrement at the bottom of the toilet, along with the flushed wastewater and debris, into the sewer pipe. Currently, the flushing water path and the flushing drainage path are pumped by two separate pumps. This pumping method makes the internal water system structure of the toilet more complex, and the manufacturing cost of the toilet is correspondingly higher. Utility Model Content
[0004] The purpose of this utility model is to provide an integrated water pump device and a toilet made therefrom. Only one water pump device is needed to supply water to the flushing water path and the drainage path of the toilet, which optimizes the water supply path inside the toilet and reduces the manufacturing cost of the toilet.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:
[0006] An integrated water pump device includes a pump device body installed in a toilet. The pump device body includes an impeller pump and a valve body. The impeller pump is connected to the valve body. The impeller pump is provided with an inlet and an outlet. The valve body is provided with a flushing outlet and a flushing drain outlet, which are respectively connected to the flushing water path and the flushing drain path of the toilet, and an inlet chamber connected to the outlet. A first water control component is provided on the water path connecting the inlet chamber and the flushing drain outlet, which controls the connection or blockage of the water path between the inlet chamber and the flushing drain outlet under the action of water pressure. A second water control component is provided on the water path connecting the inlet chamber and the flushing outlet, which controls the connection or blockage of the water path at the sealing outlet. The first water control component and the second water control component are linked to control the water path between the inlet chamber and the flushing drain outlet and the flushing outlet to be in opposite on / off states.
[0007] In this design, the water pumping device consists of an impeller pump and a valve body connected together and installed inside the toilet. The impeller pump has an inlet and an outlet, pumping water from the inlet to the outlet. The outlet is connected to the inlet chamber on the valve body. The valve body has a flushing inlet and a flushing outlet. The flushing inlet is connected to the flushing water path of the toilet, and the flushing outlet is connected to the flushing water path of the toilet. When the toilet needs to flush its inner wall, the impeller pump operates at low power, and the second water control component controls the connection between the flushing inlet and the inlet chamber. At this time, the water path between the inlet chamber and the flushing outlet is sealed, and the water in the inlet chamber enters the flushing water path to flush the inner wall of the toilet at a low flow rate. When it is necessary to flush out the waste inside the toilet, the impeller pump operates at high power, and the first water control component controls the connection between the flushing outlet and the inlet chamber. At this time, the first and second water control components work together. This design seals the water passage between the inlet chamber and the flushing outlet, allowing water from the inlet chamber to enter the flushing outlet and flush away waste from the toilet bowl with a high flow rate, carrying the waste into the sewer system. After flushing, the first water control component seals the water passage between the inlet chamber and the flushing outlet. Simultaneously, the first and second water control components work together to connect the water passage between the inlet chamber and the flushing outlet. At this point, the impeller pump operates at low power again, supplying water from the inlet chamber to the flushing outlet, which in turn supplies a small amount of water to the toilet bowl, creating a water seal inside the toilet bowl. This prevents odors from the sewer system from escaping and polluting the environment. This technical solution uses a single pump to supply water to both the flushing and flushing outlets inside the toilet bowl, reducing the number of pumps and optimizing the water supply system. The reduced number of pumps also lowers the manufacturing cost of the toilet.

The pressure plate is connected to the lower end of the control cylinder. A pressure chamber connected to the first water passage cavity and the water inlet cavity is formed between the pressure plate and the control cylinder. One end of the first spring acts on the pressure plate, and the other end acts on the lower cover. Under the combined action of the water pressure in the pressure chamber and the first spring, the first water control assembly is formed to control the connection or blockage of the water passage between the water inlet cavity and the flushing and draining port.
[0010] Optionally, the top wall of the control cylinder is provided with a water inlet hole, and a one-way valve disc is fixed to the top wall of the control cylinder at the water inlet hole. The top surface of the pressure plate is provided with a top rod for pressing the one-way valve disc. The pressure plate is provided with a first water outlet hole located on the side of the top rod. The lower cover is provided with a second water outlet hole. The side wall of the control cylinder is provided with a water passage connecting the water pressure chamber and the first water passage chamber. There is a gap between the outer sleeve and the side wall of the control cylinder. The outer sleeve is fixedly connected to the inner wall of the valve body.
[0011] Optionally, the second water control assembly includes a control rod, a sealing plug, and a second spring. The lower end of the control rod is connected to the top of the control cylinder.

One end of the second spring acts on the inner wall of the second water passage cavity, and the other end acts on the sealing plug. The bottom surface of the sealing plug contacts the top of the control rod.

[0013] Optionally, the impeller pump and the valve body are connected by screws, and a fourth sealing ring is provided at the connection between the impeller pump and the valve body.

[0016] The beneficial effects of this utility model are:
[0017] In this invention, when the toilet needs to be flushed, the impeller pump operates at low power, pumping water. The second water control component connects the water passage between the flushing inlet and the inlet chamber, sealing the water passage between the inlet and the flush outlet. Water from the inlet chamber then enters the flushing path to flush the toilet's inner wall at a low flow rate. When it is necessary to flush out waste from inside the toilet, the impeller pump operates at high power, and the first water control component connects the water passage between the flush outlet and the inlet chamber. At this time, the first and second water control components work in tandem. The second water control component seals the water passage between the inlet chamber and the flushing inlet, allowing water from the inlet chamber to enter the flushing path and flush out the waste from inside the toilet at a high flow rate. The water is carried into the sewer pipe. After flushing, the first water control component seals the water passage between the inlet chamber and the flush outlet. At the same time, the first and second water control components work together to connect the water passage between the inlet chamber and the flush outlet. At this time, the impeller pump operates at low power again, pumping water from the inlet chamber to the flush outlet, and the flush outlet continues to deliver a small amount of water to the toilet bowl, achieving a water seal inside the toilet bowl and preventing odors from the sewer pipe from spreading to the outside of the toilet bowl and polluting the environment. This technical solution can supply water to the flushing and drainage passages inside the toilet bowl separately with a single pumping device, reducing the number of pumps and thus optimizing the water supply path inside the toilet bowl.

[0024] Example 1
[0025] An integrated water pump device includes a pump body 43 installed inside a toilet. The pump body 43 includes an impeller pump 02 and a valve body 18. The impeller pump 02 is connected to the valve body 18. The impeller pump 02 is provided with an inlet 03 and an outlet 04. The valve body 18 is provided with a flushing inlet 12 and a flushing outlet 20 that are respectively connected to the toilet flushing water path 36 and the flushing drain path 47, and an inlet chamber 01 that is connected to the outlet 04. The inlet chamber 01 is connected to the flushing outlet 47. The water path connected to the drain outlet 20 is equipped with a first water control component that controls the connection or blockage of the water path between the water inlet chamber 01 and the flushing outlet 20 under water pressure. The water path connecting the water inlet chamber 01 and the flushing outlet 12 is equipped with a sealing outlet 16 and a second water control component that controls the opening and closing of the water path at the sealing outlet 16. The first water control component and the second water control component work together to control the water path between the water inlet chamber 01 and the flushing outlet 20 and the flushing outlet 12 to be in opposite on / off states.
[0026] In this embodiment, as Figure 1As shown, the water pumping device consists of an impeller pump 02 and a valve body 18 connected together and installed inside the toilet. The impeller pump 02 has an inlet 03 and an outlet 04. The impeller pump 02 pumps water from the inlet 03 to the outlet 04. The structure and pumping principle of the impeller pump 02 are existing technologies. The outlet 04 of the impeller pump 02 is connected to the inlet chamber 01 on the valve body 18. The valve body 18 is provided with a flushing port 12 and a flushing outlet 20. The flushing port 12 is connected to the flushing water path 36 of the toilet, and the flushing outlet 20 is connected to the toilet's flushing water path 36. When flushing channel 47 is connected, and the toilet needs to be flushed, impeller pump 02 operates at low power to pump water. The second water control component connects the water passage between flushing port 12 and inlet chamber 01. At this time, the water passage between inlet chamber 01 and flushing port 20 is sealed, and the water in inlet chamber 01 enters flushing channel 36 to flush the toilet's inner wall at a low flow rate. When it is necessary to flush out waste from inside the toilet, impeller pump 02 operates at high power, and the first water control component connects the water passage between flushing port 20 and inlet chamber 01. At this time, the first and second water control components work together. The second water control component seals the water passage between the inlet chamber 01 and the flushing outlet 12, allowing water from the inlet chamber 01 to enter the flushing drain 47 and flush away the waste from the toilet bowl in a large flow, carrying the waste into the sewer pipe. After flushing is complete, the first water control component seals the water passage between the inlet chamber 01 and the flushing outlet 20. Simultaneously, the first and second water control components work together to ensure that water flows between the inlet chamber 01 and the flushing outlet 12... When the circuit is connected, the impeller pump 02 starts pumping water at low power again. The inlet chamber 01 supplies water to the flushing outlet 12, which in turn supplies a small amount of water to the toilet bowl. This creates a water seal inside the toilet bowl, preventing odors from the sewer pipes from escaping and polluting the environment. This technical solution can supply water to the flushing water path 36 and the flushing drainage path 47 inside the toilet bowl with a single pump, reducing the number of pumps and thus optimizing the water supply path inside the toilet bowl. The reduced number of pumps also lowers the manufacturing cost of the toilet bowl.
[0027] Furthermore, the valve body 18 is provided with an upper cover 13 at the upper end and a lower cover 30 at the lower end. The flushing water inlet 12 is located on the top of the upper cover 13, the water inlet chamber 01 and the flushing water outlet 20 are located on the side of the valve body 18, and the first water control component is located below the second water control component.
[0028] Specifically, a second sealing ring 09 is pressed between the upper cover 13 and the valve body 18, and a third sealing ring 29 is pressed between the lower cover 30 and the valve body 18. The second sealing ring 09 and the third sealing ring 29 can improve the sealing performance of the valve body 18. The impeller pump 02 is connected to the valve body 18 by screws 07. A fourth sealing ring 06 is provided at the connection between the impeller pump 02 and the valve body 18. The fourth sealing ring 06 can improve the sealing performance at the connection and prevent water leakage.
[0029] Furthermore, the first water control assembly includes a control cylinder 49, a first spring 28, and a pressure plate 27. An outer sleeve 23 and an outer sleeve 51 formed by the inner wall of the valve body 18 are slidably sleeved on the outside of the control cylinder 49. The outer sleeve 51 is located above the outer sleeve 23. A first water passage chamber 21 communicating with the flushing / draining port 20 is formed between the outer sleeve 23 and the outer sleeve 51. A first sealing ring 05 that cooperates with the outer sleeve 51 is embedded in the top side wall of the control cylinder 49. The outer sleeve 23 and the inner wall of the valve body above it form a first water passage chamber communicating with the flushing / draining port 20. The control cylinder 49 has a first sealing ring 05 embedded in its top side wall. The top of the control cylinder 49 is connected to the second water control assembly. The control cylinder 49 is convex. The pressure plate 27 is connected to the lower end of the control cylinder 49. The pressure plate 27 and the control cylinder 49 form a pressure chamber 26 that is connected to the first water passage chamber 21 and the water inlet chamber 01. One end of the first spring 28 acts on the pressure plate 27 and the other end acts on the lower cover 30. Under the combined action of the water pressure in the pressure chamber 26 and the first spring 28, the first water control assembly is formed to control the connection or blockage of the water passage between the water inlet chamber 01 and the flushing outlet 20.
[0030] Furthermore, the top wall of the control cylinder 49 is provided with a water inlet hole 08, and a one-way valve disc 19 fixed to the inner top wall of the control cylinder 49 is provided at the water inlet hole 08. The top surface of the pressure plate 27 is provided with a top rod 24 for pressing the one-way valve disc 19. The pressure plate 27 is provided with a first water outlet hole 32 located on the side of the top rod 24. The lower cover 30 is provided with a second water outlet hole 31. The side wall of the control cylinder 49 is provided with a water passage 25 that connects the water pressure chamber 26 and the first water passage chamber 21. There is a gap 22 between the outer sleeve 23 and the side wall of the control cylinder 49. The outer sleeve 23 is fixedly connected to the inner wall of the valve body 18.
[0031] In this embodiment, the specific working principle of the first water control component is as follows: When the toilet needs to flush its inner wall, the impeller pump 02 operates at low power to pump water. The water is pumped from the inlet 03 to the outlet 04, and then enters the inlet chamber 01 of the valve body 18. The water passage between the flushing outlet 12 and the inlet chamber 01 is connected. At this time, the water passage between the inlet chamber 01 and the flushing outlet 20 is sealed, and the water in the inlet chamber 01 enters the flushing water passage 36 to flush the inner wall of the toilet with a small flow rate. When it is necessary to flush the excrement inside the toilet, the impeller pump 02 operates at high power, and a large amount of water enters the inlet chamber 01. The water in the inlet chamber 01 pushes down to open the one-way valve 19 and enters the pressure chamber 26 inside the control cylinder 49 through the inlet hole 08. A small amount of water will flow out from the first outlet hole 32. The second water outlet 31 flows into the toilet bowl. The diameters of the first water outlet 32 and the second water outlet 31 are both small, so very little water flows out. This creates a pressure buildup in the pressure chamber 26. The generated water pressure overcomes the elastic force of the first spring 28. The pressure plate 27 drives the control cylinder 49 to move downward until the first sealing ring 05 moves downward past the upper end of the first water passage chamber 21. At this point, the water passage between the inlet chamber 01 and the first water passage chamber 21 is connected, which in turn connects the flushing outlet 20 and the inlet chamber 01. The greater the working power of the impeller pump 02, the more water it draws in, the greater the water pressure generated in the pressure chamber 26, the greater the downward displacement of the control cylinder 49, the larger the water passage area of the first water passage chamber 21, and the more water is delivered to the flushing outlet 20, resulting in a better flushing effect for the toilet. Simultaneously, the first and second water control components work together to seal the water passage between the inlet chamber 01 and the flushing outlet 12. A large amount of water from the inlet chamber 01 then enters the flushing outlet 20. At the same time, water from the pressure chamber 26 is also transported through the gap 22 between the outlet 25, the outer sleeve 23, and the control cylinder 49 to the flushing outlet 20. From there, the water is transported to the flushing drain 47 to flush away the waste inside the toilet bowl with a large flow, carrying it into the sewer system. After flushing, when the water pressure in the pressure chamber 26 is insufficient to overcome the elasticity of the first spring 28, the first... Spring 28 returns to its original position and pushes upward against plate 27, causing control cylinder 49 to move upward until the first sealing ring 05 is above the upper end of the first water passage chamber 21. Control cylinder 49 controls the water passage seal between water inlet chamber 01 and flush outlet 20. Control cylinder 49 and the second water control component work together to connect the water passage between water inlet chamber 01 and flush outlet 12. At this time, impeller pump 02 pumps water again at low power. Water inlet chamber 01 supplies water to flush outlet 12. Flushing outlet 12 continues to deliver a small amount of water to the toilet, achieving a water seal inside the toilet and preventing odors from the sewer pipes from spreading to the outside of the toilet and polluting the environment.
[0032] Furthermore, the second water control assembly includes a control rod 17, a sealing plug 15, and a second spring 14. The lower end of the control rod 17 is connected to the top of the control cylinder 49. The side wall of the control rod 17 is provided with a water passage groove 10 that communicates with the water inlet chamber 01. The valve body 18 is provided with a second water passage chamber 11 that communicates with the flushing water outlet 12. One end of the second spring 14 acts on the inner wall of the second water passage chamber 11, and the other end acts on the sealing plug 15. The bottom surface of the sealing plug 15 contacts the top of the control rod 17. The second spring 14 is initially in a compressed state, so that the water passage at the sealing outlet 16 is in a connected state.
[0033] In this embodiment, the working principle of the second water control component is as follows: the control rod 17 is slidably sleeved with the inner wall of the valve body 18, and the lower end of the control rod 17 is fixedly connected to the top end of the control cylinder 49. The up-and-down movement of the control cylinder 49 can drive the control rod 17 to move up and down. When the impeller pump 02 is working at low power or not working, the top end of the control rod 17 is located above the water seal 16. The control rod 17 contacts the bottom surface of the sealing plug 15 and presses the second spring 14 upward, so the water passage at the water seal 16 is connected and water enters. Water in chamber 01 can enter the second water passage chamber 11 through water tank 10, and then be output to the flushing water passage 36 of the toilet from flushing water outlet 12; when impeller pump 02 is working at high power, when control cylinder 49 moves down, control rod 17 moves down with it, and second spring 14 pushes down to seal plug 15 until the upper end of control rod 17 is below sealing water outlet 16. At this time, sealing plug 15 seals sealing water outlet 16 under the action of second spring 14. At this time, water in inlet chamber 01 enters control cylinder 49 from first inlet hole 08.

The inlet end of the existing flushing and drainage channel 48 is concave downward. The flushing sewage and excrement are collected here and finally carried away by a large amount of water to the drain outlet 44 and flow into the sewer pipe. Then, the water transported by the flushing water path 36 is collected in the concave part of the flushing and drainage channel 48 and forms a liquid seal.
[0038] The specific flushing principle of the toilet body 33 is as follows: First, the controller (existing technology) inside the toilet controls the motor in the pump device to start at a low power. A small amount of water is drawn in from the inlet 03 and pumped to the outlet 04, and finally enters the inlet chamber 01 of the valve body 18. At this time, the sealing plug 15 is located above the sealing port 16, and the water passage at the sealing port 16 is in the connected state. The water in the inlet chamber 01 then enters the flushing water passage 36 to flush the inner wall of the toilet with a small flow rate.
[0039] Next, the controller controls the impeller pump 02 to operate at high power, and a large amount of water enters the inlet chamber 01. A small amount of water passes through the water tank 10 and enters the second water passage chamber 11. The large amount of water pushes down to open the one-way valve 19 and enters the pressure chamber 26 inside the control cylinder 49 through the inlet hole 08. A small amount of water flows out from the first outlet hole 32 and the second outlet hole 31 into the toilet bowl. The diameters of the first outlet hole 32 and the second outlet hole 31 are both small, so very little water flows out. This creates a pressure buildup phenomenon in the pressure chamber 26, and the generated water pressure overcomes the first spring. The elastic force of 28 causes the pressure plate 27 to drive the control cylinder 49 to move downward until the first sealing ring 05 moves downward beyond the upper end of the first water passage chamber 21. At this point, the water passage between the water inlet chamber 01 and the first water passage chamber 21 is connected, which in turn connects the water passage between the flushing outlet 20 and the water inlet chamber 01. The greater the working power of the impeller pump 02, the more water it sucks in, the greater the water pressure generated in the pressure chamber 26, the greater the downward displacement of the control cylinder 49, the larger the water passage area of the first water passage chamber 21, and the more water is delivered to the flushing outlet 20, resulting in a better flushing effect for the toilet. Simultaneously, the control cylinder 49 moves downward, causing the control rod 17 to move downward until the water passage at the sealing port 16 is sealed by the blockage 15. A large amount of water from the inlet chamber 01 then enters the flushing outlet 20. At the same time, water from the pressure chamber 26 is also transported through the gap 22 to the flushing outlet 20, and then from the flushing outlet 20 to the flushing drain 47 to flush away the waste inside the toilet bowl with a large flow, carrying the waste into the sewer pipe. After flushing is complete, when the water pressure in the pressure chamber 26 drops to a level insufficient to overcome the elastic force of the first spring 28, the first spring 28 resets and pushes upward against the pressure plate 27, causing... The control cylinder 49 moves upward until the first sealing ring 05 is above the upper end of the first water passage chamber 21. The control cylinder 49 controls the water passage seal between the water inlet chamber 01 and the flush outlet 20. The control cylinder 49 drives the control rod 17 to move upward, and the sealing plug 15 is pushed upward by the control rod 17. The water passage at the sealing outlet 16 is connected. At this time, the impeller pump 02 pumps water again at low power. The water inlet chamber 01 supplies water to the flush outlet 12. The flush outlet 12 continues to deliver a small amount of water to the toilet, achieving a water seal inside the toilet and preventing odors from the sewer pipes from spreading to the outside of the toilet and polluting the environment.
