Description

Technical Field

[0001] The utility model relates to the technical field of toilet bodies, in particular to a toilet appliance composed of a split-type water pump mechanism. Background Art

[0002] The toilet body is an indispensable living facility in every family's life. The toilet body is generally divided into squatting type or sitting type. Different toilet bodies can be installed according to different family needs. The sewage outlet at the bottom of the toilet body is connected to the sewer pipe. There is a curved flow channel inside the toilet body connected to the sewage outlet. The upper edge of the toilet body cavity is provided with a circular flushing water channel. After the curved flow channel discharges the excrement, water will be stored in the flow channel for liquid sealing to prevent the odor in the sewer pipe from being emitted through the curved flow channel.

[0003] At present, the interior of a toilet body is provided with a flushing water channel and a flushing drainage channel. The flushing water channel flushes the debris on the inner wall of the toilet body to the bottom. The flushing drainage channel has a large amount of water, which carries the excrement at the bottom of the toilet body together with the flushed sewage and debris to the sewer pipe. The water supply of the flushing water channel and the flushing drainage channel of the toilet body is realized by a pumping mechanism having both a pump and a valve. This integrated pumping mechanism is more troublesome to maintain. If any one of the components needs to be repaired, the other component needs to be removed, and the entire machine needs to be taken out for repair. Utility Model Content

[0004] The purpose of the utility model is to provide a toilet appliance composed of a split water pump mechanism, which is divided into an independent pump and valve. In this way, no matter which component needs to be repaired or replaced, it is only necessary to remove the corresponding pipeline and take out the component to be repaired or replaced. There is no need to take out the pump and valve together, which makes repair and replacement more convenient.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions:

[0006] The water inlet of described outer rim of described outer rim is connected with the water inlet of described outer rim, and the water inlet of described outer rim is connected with the sewage outlet.

[0007] In this solution, the split water pump mechanism consists of two parts, an independent impeller pump and a valve body, and is installed inside the water tank of the toilet body. The impeller pump has a first water inlet, a second water inlet and a first water outlet, a second water outlet. The impeller pump pumps water to the two water outlets through the two water inlets respectively. The valve body is provided with an inlet flow channel connected to the two water outlets at the same time. The water absorption of the two water inlets can increase the water pumping capacity of the impeller pump. A flushing water outlet and a flushing water outlet are provided on the valve body. The flushing water outlet is connected to the two water outlets.

When the toilet body needs to flush its inner wall, the flow control component controls the water path between the flushing water inlet and the water inlet flow channel to be connected, and the water inside the water inlet flow channel enters the flushing water path to flush the inner wall of the toilet body with a small flow rate. When it is necessary to flush the excrement inside the toilet body, the flushing water inlet and the water inlet flow channel are connected. When flushing, the flow control component controls the connection between the flushing water channel and the water inlet channel. The water inside the water inlet channel enters the flushing water channel through the conduit to flush the excrement inside the toilet body with a large flow rate, and discharges the excrement from the sewage outlet into the sewer pipe. After the flushing is completed, the impeller pump continues to pump water. At this time, the flow control component controls the connection between the water inlet channel and the flushing water channel again, and the flushing water outlet continues to transport water to the toilet body, realizing a water seal inside the toilet body, preventing the odor in the sewer pipe from emitting to the outside of the toilet body and polluting the environment. This technical solution can supply water to the flushing water channel and the flushing water channel inside the toilet body separately through an independent impeller pump, a valve body and a conduit inside the toilet body, and divides the water pumping mechanism into an independent pump and valve. In this way, no matter which component needs to be repaired or replaced, it is only necessary to remove the corresponding connecting pipe of the pump or valve and take out the pump or valve to be repaired and replaced.

[0029] In this embodiment, Figure 1 and Figure 2As shown, the split-type water pump mechanism consists of an independent impeller pump 02 and a valve body 33, and is installed inside the water tank 52 of the toilet body 47. The impeller pump 02 has a first water inlet 01, a second water inlet 03 and a first water outlet 05, a second water outlet 04. The impeller pump 02 pumps water to the two water outlets through the two water inlets. The valve body 33 is provided with an inlet channel 08 connected to the two water outlets at the same time. The two water inlets absorb water to increase the water pumping capacity of the impeller pump 02. The valve body 33 is provided with a flushing water outlet 28 and a flushing water outlet 23. The flushing water outlet 28 The flushing waterway 44 of the toilet body 47 is connected, the flushing outlet 23 is connected to the flushing waterway 51 of the toilet body 47, and a flow control component for controlling the on-off of the waterway is provided on the waterway connecting the flushing outlet 23 and the water inlet channel 08 and the flushing water outlet 28 and the water inlet channel 08.

When the toilet body 47 needs to be flushed, the flushing waterway 44 is connected to the inner wall of the toilet body 47. When the excreta inside the toilet bowl 47 is flushed, the flow control component controls the water channel between the flushing water channel 51 and the water inlet channel 08 to be connected. The water inside the water inlet channel 08 enters the flushing water channel 51 through the conduit 40 to flush the excreta inside the toilet bowl 47 with a large flow rate, and discharges the excreta from the sewage outlet 48 to the sewer pipe.

At this time, the flow control component controls the water inlet channel 08 to be connected with the flushing water channel 44 again, and the flushing water outlet 28 continues to supply water to the toilet bowl 47, thereby achieving a water seal inside the toilet bowl 47. In order to prevent the odor in the sewer pipe from being emitted to the outside of the toilet body 47 and polluting the environment, this technical solution can supply water to the flushing waterway 44 and the flushing waterway 51 inside the toilet body 47 respectively through an independent impeller pump 02, a valve body 33 and a conduit 40 inside the toilet body 47, and divide the split-type water pump mechanism into an independent pump and valve. In this way, no matter which component needs to be repaired or replaced, it is only necessary to remove the corresponding connecting pipe of the pump or valve and take out the pump or valve to be repaired or replaced. There is no need to take out the pump and valve together, which makes repair and replacement more convenient.

[0031] Furthermore, the valve body 33 is provided with a first water outlet 35, a first water outlet chamber 34, and a second water outlet chamber 24. The first water outlet 35 connects the water path between the water inlet channel 08 and the first water outlet chamber 34, and the second water outlet chamber 24 is connected to the flushing outlet 23. The flow control component controls the connection or blocking of the water path between the first water outlet chamber 34 and the flushing outlet 28 and the second water outlet chamber 24.

[0032] Furthermore, the flow control assembly includes a control rod 25 and a return spring 14. A pressure plate 16 is fixed to the upper end of the control rod 25. An extension plate 31 is provided at the lower end of the control rod 25. A second water outlet 30 connected to the first water outlet chamber 34 is provided on the extension plate 31.

A first water hole 11 connected to the second water passage chamber 12 is provided on the valve cover 10. One end of the return spring 14 acts on the valve cover 10, and the other end acts on the pressure plate 16. The pressure plate 16 is provided with a second water hole 15 connected to the first water passage chamber 17, a support sleeve 21 is provided on the outer side of the control rod 25, a pressure sensing chamber 20 connected to the first water passage chamber 17 is formed between the support sleeve 21 and the control rod 25, a gap 22 is provided between the support sleeve 21 and the control rod 25, a second water outlet chamber 24 is formed between the control rod 25 and the inner wall of the valve body 33, a one-way water flow control structure is provided at the lower end of the control rod 25 to control the connection or blocking of the first water outlet chamber 34 with the first water passage chamber 17, and a third water outlet 19 is opened on the control rod 25 to connect the water path between the first water passage chamber 17 and the pressure sensing chamber 20.

[0034] like Figure 3 and Figure 5As shown, the specific working principle of the flow control component is: a first water inlet chamber is provided inside the valve body 33, and a first water outlet 35 for connecting the water path between the water inlet channel 08 and the first water outlet chamber 34 is provided on the inner wall of the valve body 33, so that the water pumped to the water inlet channel 08 by the impeller pump 02 can directly enter the first water outlet chamber 34, and an extension plate 31 is integrally connected to the right side of the lower end of the control rod 25, and a second water outlet 30 is provided on the extension plate 31. When the second water outlet 30 is connected to the flushing water outlet 28, the water in the first water outlet chamber 34 enters the flushing water outlet 28 through the second water outlet 30, and is then transported to the flushing water path 44 of the toilet body 47. The extension plate 31 can move up and down with the control rod 25. When the control rod 25 moves up, it drives the extension plate 31 to move up. When the second water outlet 30 is connected to the flushing water outlet When 28 is completely staggered, the water path of the second water outlet 30 is basically blocked. A guide plate 32 is provided on the left side of the extension plate 31. The guide plate 32 can ensure that the moving path of the extension plate 31 is always vertical. The control rod 25 is circumferentially provided with a guide cylinder 09 integrally formed with the inner wall of the valve body 33. The height of the guide cylinder 09 is lower than the bottom end of the flushing and draining outlet 23. A second sealing ring 26 is circumferentially embedded in the lower end of the control rod 25. The lower end of the control rod 25 is slidably sleeved inside the guide cylinder 09. The control rod 25 and the guide cylinder 09 can slide relative to each other in the vertical direction under the action of external force. After the lower end of the control rod 25 slides out of the top of the guide cylinder 09, the first water outlet chamber 34 facilitates the connection with the second water outlet chamber 24, and then the water in the first water outlet chamber 34 can enter the flushing and draining outlet 23 and then be transported to the flushing and draining channel 51 of the toilet body 47.

[0035] The control rod 25 has a hollow cavity in the middle part, and a side plate 18 is integrally formed on the side of the upper end of the control rod 25. The side plate 18 is L-shaped and arranged vertically. The side plate 18 and the top of the side plate 18 are fixed with a pressure plate 16. A first water passage chamber 17 is formed between the pressure plate 16 and the side plate 18. The pressure plate 16, the side plate 18 and the control rod 25 form a T-shaped structure. The side plate 18 is in sliding contact with the inner wall of the valve body 33. A support sleeve 21 connected to the inner wall of the valve body 33 is provided below the side plate 18. The control rod 25 passes through the support sleeve 21. The support sleeve 21 and the control rod 25 can slide relative to each other. There is a slight gap 22 between the support sleeve 21 and the control rod 25. A third water passage 19 is provided at the bottom of the side plate 18. The second water passage 30 is located on the outside of the control rod 25. A pressure sensing chamber 20 is formed between the side plate 18 and the support sleeve 21. The third water passage 19 connects the first water passage chamber 17 and the pressure sensing chamber 2 0, a second water passage chamber 12 is formed between the pressure plate 16 and the valve cover 10, the valve cover 10 is fixedly connected to the top of the valve body 33, and a first sealing ring 13 is pressed between the valve cover 10 and the top of the valve body 33, a first water hole 11 connected to the second water passage chamber 12 and the external atmosphere is provided on the top of the valve cover 10, a second water hole 15 connected to the second water passage chamber 12 and the first water passage chamber 17 is provided on the pressure plate 16, the apertures of the first water hole 11 and the second water hole 15 are relatively small, one end of the return spring 14 acts on the top surface of the pressure plate 16, and the other end acts on the bottom surface of the valve cover 10, the first water hole 11 and the second water hole 15 can prevent the internal air pressure from hindering the movement of the control rod 25, and the lower end of the control rod 25 is provided with a water inlet hole 29, and a one-way diaphragm 27 is fixed to the lower end of the control rod 25. The one-way diaphragm 27 controls that water can only enter the first water passage chamber 17 from the first water outlet chamber 34.

[0036] The controller is provided with three stages of motor working power. First, the controller controls the motor to start at low power, and the motor speed is relatively low. The amount of water sucked in by the first water inlet 01 and the second water inlet 03 is relatively small. After the source water enters the first water outlet chamber 34 in the valve body 33 from the impeller pump 02, it pushes open the one-way diaphragm 27 and enters the first water passage chamber 17 and the pressure sensing chamber 20. The water pressure in the pressure sensing chamber 20 is the same as the water pressure in the first water passage chamber 17. The downward water pressure in the pressure sensing chamber 20 acts on the support sleeve 21, and the upward water pressure acts on the bottom surface of the side plate 18 and the bottom surface of the pressure plate 16. At this time, the water pressure cannot overcome the elastic force of the reset spring 14 and the liquid level difference force in the second water passage chamber 12. At this time, the control lever 25 does not move, and the second water passage 30 connects the water channel between the first water outlet chamber 34 and the flushing water port 28, so that water can be supplied to the flushing water channel 44 of the toilet body 47.

[0037] Next, the controller controls the motor to work at high power, sucking a large amount of water into the first water outlet chamber 34. Since the flushing water port 28 has a small diameter and a throttling effect, a large amount of water is located in the first water outlet chamber 34, thereby generating a pressure buildup. The water pressure in the first water outlet chamber 34 pushes open the one-way diaphragm 27, and water enters the first water chamber 17 from the water inlet 29, and enters the pressure sensing chamber 20 from the third water port 19. The water pressure in the pressure sensing chamber 20 overcomes the elastic force of the return spring 14, i.e., the second water chamber 20. The liquid level difference in the water chamber 12 pushes the side plate 18 and the pressure plate 16 upward, causing the side plate 18, the pressure plate 16, and the control rod 25 to move upward. The pressure plate 16 compresses the return spring 14. After the control rod 25 moves up to its lower end and slides out of the upper end of the guide cylinder 09, a large amount of water in the first water outlet chamber 34 enters the second water outlet chamber 24 and is transported from the flushing outlet 23 through the conduit 40 to the flushing drainage path 51 of the toilet body 47. The flushing outlet 23 is a large-diameter water outlet, which can achieve large-volume flushing and drainage of the toilet. After the water in the first water outlet chamber 34 is discharged, the water volume decreases sharply, the one-way diaphragm 27 closes the water inlet hole 29, and the water in the pressure-sensing chamber 20 and the first water-transfer chamber 17 flows into the second water-transfer chamber 12 through the second water hole 15, producing a pressure relief effect. The water pressure in the pressure-sensing chamber 20 is not reduced enough to overcome the elastic force of the return spring 14 and the liquid level drop force in the second water-transfer chamber 12. The return spring 14 returns to its original position and pushes the pressure plate 16 downward, causing the control rod 25 to move downward until the lower end of the control rod 25 is inserted into the guide cylinder 09. The second sealing ring 26 seals the water path between the first water outlet chamber 34 and the second water outlet chamber 24. At this time, the second water outlet 30 is connected to the water path between the first water outlet chamber 34 and the flushing water outlet 28 again; then the controller controls the motor to work at low power again, and the impeller pump 02 pumps a small amount of water into the first water outlet chamber 34, and transports it to the flushing water path 44 through the flushing water outlet 28. The water transported to the toilet body 47 realizes liquid sealing on the toilet body 47, thereby preventing the odor in the sewer pipe from being emitted and polluting the environment.

[0038] like Figure 1 As shown, further, the flushing outlet 23 is connected to the water inlet end 41 of the upper side wall of the conduit 40 through a first connecting pipe 42, the lower end of the conduit 40 is connected to the inner wall of the toilet body 47, the water outlet end at the bottom of the conduit 40 is connected to the flushing water channel 51 through a third connecting pipe 53, and the flushing water outlet 28 is connected to the flushing water channel 44 through a second connecting pipe 43.

[0039] Furthermore, the top of the conduit 40 is higher than the liquid level in the water tank 52, and the sidewall of the conduit 40 is provided with an air hole 39 that is higher than the liquid level. Specifically, the conduit 40 is further provided with the air hole 39, which has a smaller aperture and is higher than the liquid level in the water tank 52. The air hole 39 is to prevent the siphon phenomenon from occurring in the conduit 40 during flushing. The water inlet end 41 of the existing flushing channel 49 is concave downward, and the flushed sewage and excrement are collected here, and finally carried away by a large amount of water to the sewage outlet 48 and flow into the sewer pipe. Then, the water transported by the flushing waterway 44 is collected in the concave portion 50 of the flushing channel 49 and forms a liquid seal.

[0040] like Figure 4 and Figure 5 As shown, further, the conduit 40 is integrally formed with the side wall of the valve body 33, the flushing outlet 23 is connected to the water inlet end 41 at the top of the conduit 40, the water outlet end at the lower end of the conduit 40 is connected to the flushing water channel 51 through the seventh connecting pipe 57, the flushing water outlet 28 and the flushing water channel 44 are connected through the fourth connecting pipe 54, the first water outlet 05 and the third water inlet 07 are connected through the fifth connecting pipe 55, and the second water outlet 04 and the fourth water inlet 06 are connected through the sixth connecting pipe 56.

[0041] Furthermore, a fixing plate 38 connected to the inner wall of the toilet body 47 is provided on the side wall of the conduit 40 .

[0042] The specific flushing principle of the toilet body 47 is: first, the controller controls the motor of the impeller pump 02 to start at low power, and the motor shaft 36 rotates to drive the impellers 37 at both ends to rotate. A small amount of water is sucked in by the first water inlet 01 and the second water inlet 03 and pumped to the first water outlet 05 and the second water outlet 04 respectively, and then transported to the third water inlet 07 and the fourth water inlet 06 respectively through the pipeline. Finally, it is collected by the water inlet channel 08 in the valve body 33 and transported to the first water outlet chamber 34 through the first water outlet 35. The water in the first water outlet chamber 34 pushes open the one-way diaphragm 27 and enters the first water passage chamber 17 and the pressure sensing chamber 20. The water pressure in the pressure sensing chamber 20 is the same as that in the first water passage chamber 17. The water pressure is the same. The downward water pressure in the pressure-sensing chamber 20 acts on the support sleeve 21, and the upward water pressure acts on the bottom surface of the side plate 18 and the bottom surface of the pressure plate 16. The water pressure at this time cannot overcome the elastic force of the reset spring 14 and the liquid level drop force in the second water chamber 12. At this time, the control lever 25 does not move, and the second water outlet 30 connects the water channel between the first water outlet chamber 34 and the flushing water outlet 28. The flushing water outlet 28 transports water to the flushing water pipe in the toilet body 47, and then enters the annular flushing water channel 44 through the water flow channel. At this time, the inner wall of the inner cavity of the toilet body 47 can be flushed, and the flushed debris and sewage are collected into the recess 50 of the flushing flow channel 49 through the wash outlet 45.

[0043] Next, the controller controls the motor to work at high power, the speed of the rotating shaft 36 increases, and a large amount of water is pumped by the impeller pump 02 to the first water outlet 05 and the second water outlet 04, and then respectively transported to the third water inlet 07 and the fourth water inlet 06 through the pipeline, and finally collected into the first water outlet chamber 34 through the water inlet channel 08. The diameter of the flushing water outlet 28 is small, which has a throttling effect. Therefore, a large amount of water is located in the first water outlet chamber 34, thereby generating a pressure. The water pressure in the first water outlet chamber 34 pushes open the one-way diaphragm 27, and water flows out from the water inlet hole. 29 enters the first water passage chamber 17 and enters the pressure sensing chamber 20 through the third water passage 19. The water pressure in the pressure sensing chamber 20 overcomes the elastic force of the return spring 14, that is, the liquid level difference force in the second water passage chamber 12, and pushes the side plate 18 and the pressure plate 16 upward, so that the side plate 18, the pressure plate 16, and the control rod 25 move upward. The pressure plate 16 compresses the return spring 14. After the control rod 25 moves upward to its lower end and slides out of the upper end of the guide cylinder 09, a large amount of water in the first water outlet chamber 34 enters the second water outlet chamber 24 and is discharged from the flushing outlet 23. The flushing drainage channel 51 of the toilet is sent to the flushing drainage channel 51, and the flushing drainage outlet 23 is a large-diameter water outlet, which realizes large-volume flushing of the toilet. The excrement is flushed by the large-volume flushing and discharged from the flushing channel 49 to the sewage outlet 48, and finally discharged into the sewer pipe. When the large-volume flushing is carried out, a siphon effect is generated, which sucks away the flushed debris and sewage and discharges them into the sewer pipe; when the water in the first water outlet chamber 34 is discharged, the water volume decreases sharply, the one-way diaphragm 27 closes the water inlet hole 29, and the water in the pressure sensing chamber 20 and the first water passage chamber 17 is discharged from the second water hole 15 flows into the second water passage chamber 12, generating a pressure relief effect. The water pressure in the pressure-sensing chamber 20 decreases insufficiently to overcome the elastic force of the return spring 14 and the liquid level difference in the second water passage chamber 12. The return spring 14 returns to its original position and pushes the pressure plate 16 downward, causing the control rod 25 to move downward until the lower end of the control rod 25 is inserted into the guide cylinder 09. The second sealing ring 26 seals the water path between the first water outlet chamber 34 and the second water outlet chamber 24. At this time, the second water outlet 30 is connected to the water path between the first water outlet chamber 34 and the flushing outlet 28 again.

[0044] Finally, the controller controls the motor to work at low power again, and the impeller pump 02 pumps a small amount of water into the first water outlet chamber 34, and transports it to the flushing water channel 44 through the pipeline connected to the flushing water outlet 28. The flushing water channel 44 transports the water to the recess 50 of the flushing drain in the toilet body 47 for temporary storage. The liquid level just exceeds the wash drain outlet 45, so that the toilet body 47 can be liquid-sealed to prevent the odor in the sewer pipe from being emitted and polluting the environment.

[0045] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Based on the technical essence of the present invention and within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement of the above embodiment shall still fall within the scope of protection of the technical solution of the present invention.
