[0014] In the above technical scheme, the agent supply assembly, the foaming device and the flushing device are installed at different positions, when a certain module fails or needs to be maintained, the specific module with problems can be maintained and replaced alone, and the complexity and time cost of maintenance are greatly reduced.

[0015] As preferred, the agent supply assembly comprises an agent tank and a delivery pump body, the input end of the delivery pump body is in communication with the agent tank, and the output end of the delivery pump body is in communication with the agent inlet pipe.

[0016] In the above technical solution, the agent tank is used to store the foaming agent, and the delivery pump body is responsible for the stable delivery of the foaming agent in the agent tank to the foaming device.

[0020] In the above technical solution, when the water flow enters the expansion section of the foaming pipe through the first contraction section of the connector, a negative pressure area will be formed in the gap area between the expansion section and the first contraction section due to the increase of the flow rate. This is because the increase of the flow rate leads to the decrease of the pressure in this area, thereby forming a pressure difference with the external atmospheric pressure. Since the expansion section is sleeved outside the first contraction section and is also provided with an air inlet pipe in communication with the negative pressure area, the external air will be sucked into the foaming pipe and mixed with the water flow. Without an additional power source, the air can be sucked in by the power of the water flow itself, thereby saving energy cost.

[0021] Preferably, the tail section is provided with a spoiler.

[0022] In the above technical solution, the tail section is located downstream of the middle section and the expansion section, and the spoiler in the tail section fully mixes the foaming agent, water and air, changes the direction of the mixture and makes the speed distribution uneven, so that vortexes and turbulence are generated in the fluid, greatly increasing the contact area between water, foaming agent and air, so that they can be more fully mixed together. This strong mixing effect can ensure that the foaming agent is uniformly dispersed in the water, and the air is also more uniformly dissolved or dispersed in the water, thereby forming a more delicate and uniform foam, so that the intelligent toilet produces more abundant and delicate foam during flushing, which can better cover the surface of the toilet bowl, prevent water from splashing, suppress odors, etc., thereby optimizing the user's experience.

[0023] Preferably, the foaming assembly further comprises an air pump, and the air outlet of the air pump is in communication with the air inlet pipe of the foaming device.

[0024] In the above technical solution, the air pump delivers air to the foaming device, so that the air is mixed with water and foaming agent, which helps to form more stable and uniform foam.

[0025] Preferably, the water supply assembly further comprises a flushing pump, the flushing pump is arranged between the water inlet of the flushing valve and the external water source, the water inlet of the flushing pump is in communication with the external water source, and the water outlet of the flushing pump is in communication with the water inlet of the flushing valve.

[0026] In the above technical solution, the flushing pump is used to deliver water to the foaming device, and when the intelligent toilet is flushing and foaming, the flushing pump is started synchronously to pressurize the water inlet, avoiding the situation that the water pressure of tap water is insufficient, thereby optimizing the effect of flushing and foaming. When foam flushing is performed, the flushing valve controls the first water outlet to open, and the flushing pump pressurizes the water flow, so that the water flow is fully mixed with the foaming agent and then quickly sprayed from the upper spray opening. This rapid foaming speed ensures that the foam can quickly cover the inner wall of the toilet bowl, achieving the effect of revolving and moisturizing the wall, and improving the cleaning ability.

[0027] Compared with the prior art, the utility model has the following advantages:

[0053] Embodiment 4

[0054] Based on embodiment 2, as shown in Figure 2 and Figure 7 The intelligent toilet includes a toilet base 1, and the water supply assembly further includes a flushing pump 32 and a lower nozzle 34, the flushing pump 32 is arranged between the water inlet of the flushing valve 33 and the external water source, the flushing pump 32 includes a pump water inlet 321, which is the water inlet of the flushing pump 32, and is in communication with the external water source through a pipeline, the water outlet of the flushing pump 32 is directly connected and communicated with the water inlet of the flushing valve 33, and the two are sealed by an O-ring.

[0055] The flushing pump 32 is used to deliver water to the foaming device 42. The water is directly extracted from the external water source by the flushing pump 32, so that the water flow is no longer directly dependent on the water pressure of the tap water. The water pressure of the tap water may fluctuate due to various factors (such as water supply system load, pipeline aging, etc.).

The cover body 81 covers the top of the toilet cover assembly 8. An agent adding port 7 is formed on the cover body 81 corresponding to the position of the supply assembly. An agent plug 5 is detachably mounted on the agent adding port 7. It can be understood that the toilet cover assembly 8 and the toilet base 1 can be connected through thread connection or clamping connection, which is a detachable connection method commonly used in the art. It should be noted that the detachable connection between the output end of the supply assembly and the agent inlet pipe 45 through the joint assembly 2 can be achieved by direct connection or indirect connection. That is, the output end of the supply assembly and the agent inlet pipe 45 can be directly connected through the joint assembly 2 without other components in between. Alternatively, other components can be arranged between the two, and the two are connected through the joint assembly 2 and the intermediate components.

When the agent supply assembly fails, the connection between the agent supply assembly and the foaming device 42 is disconnected, the cover body 81 is opened to repair or replace the faulty module, and then the cover body 81 is installed in place; when the foaming device 42 fails, the connection between the agent supply assembly and the foaming device 42 is disconnected, the toilet cover assembly 8 is removed, the faulty module in the toilet base 1 is repaired or replaced, and then the toilet cover assembly 8 is installed in place.

It can be understood that the agent tank 41 can also be designed as a closed container of any shape, and the closed container is provided with an opening which is communicated with the agent adding port 7.

[0060] In the above intelligent toilet, the agent tank 41 is used to store the foaming agent, the delivery pump body 43 is responsible for stably delivering the foaming agent in the agent tank 41 to the foaming device 42, the delivery pump body 43 can accurately control the delivery amount of the foaming agent, which avoids the waste of the foaming agent, and the delivery pump body 43 can meet the diversified foaming amount demand in different modes by adjusting the delivery amount of the foaming agent.

[0061] In this embodiment, as shown in Figure 4As shown, the joint assembly 2 includes a first joint 21 and a second joint 22 connected detachably, and the joint assembly 2 is in the form of an O-ring seal, and the locking of the two ends of the joint is completed by inserting and then rotating. The first joint 21 of the joint assembly 2 is connected to the delivery pump body 43 through a hose, and the second joint 22 of the joint assembly 2 is connected to the agent inlet pipe 45 through a hose. It can be understood that the first joint 21 can also be connected to the agent inlet pipe 45 through a hose, and the second joint 22 can be connected to the delivery pump body 43 through a hose to connect the agent inlet pipe 45 and the agent supply assembly.

[0062] During on-site installation, the first joint 21 and the second joint 22 are simply butted, and the connection between the delivery pump body 43 and the agent inlet pipe 45 can be quickly completed. This installation method is simple and fast, greatly reducing the installation time and complexity. Due to the detachability of the joint assembly 2, when the delivery pump body 43 or the agent inlet pipe 45 needs to be maintained, the relevant parts can be easily removed for maintenance or replacement by simply disconnecting the joint, simplifying the maintenance process and improving the maintenance efficiency. The hose connection can adapt to different installation positions and angles, enhancing flexibility and adaptability.

[0063] In this embodiment, as shown in Figure 8 The foaming assembly 4 further includes a proportional distributor 44 having one inlet and two outlets. The proportional distributor 44 is arranged between the delivery pump body 43 and the foaming device 42. The agent tank 41 is provided with a liquid outlet and a liquid return port. The input end of the delivery pump body 43 is in communication with the liquid outlet, the output end of the delivery pump body 43 is in communication with the inlet, and the first outlet 441 in communication with the agent inlet pipe 45 is the first outlet of the two outlets, and the second outlet 442 in communication with the liquid return port is the second outlet.

[0064] In the above-mentioned intelligent toilet, when the flow rate output by the delivery pump body 43 exceeds the required amount of the foaming device 42, the excess foaming agent can be returned to the agent tank 41 through the second outlet 442 in communication with the liquid return port. By accurately controlling the flow rate distribution of the foaming agent, waste caused by excessive use or insufficient use can be reduced, and the use cost can be reduced. It can be understood that the flow rate of the delivery pump body 43 is exactly suitable for the required dose of the foaming function, so the proportional distributor 44 can also not be used.

[0065] In another embodiment, the intelligent toilet is a one-piece structure, and the foaming assembly and the flushing device are connected through a pipeline.

[0067] Based on Embodiment 5, as shown in Figure 5As shown, the intelligent toilet, the foaming device 42 comprises a connecting head 47, a foaming pipe 48 and a spray head 49 connected in sequence and in communication, the connecting head 47 has a first contraction section 471, the foaming pipe 48 comprises an expansion section 481, an intermediate section 482 and a tail section 483 communicated in sequence from upstream to downstream, the expansion section 481 is sleeved outside the first contraction section 471, a gap is provided between the inner wall of the expansion section 481 and the outer diameter of the first contraction section 471 to form a negative pressure area, the expansion section 481 is provided with an air inlet pipe 487 communicated with the negative pressure area, and the agent inlet pipe 45 is arranged in the intermediate section 482. The foaming device 42 is designed as a structure similar to a Venturi tube.

[0068] In the above intelligent toilet, when the water flow enters the expansion section 481 of the foaming pipe 48 through the first contraction section 471 of the connecting head 47, due to the increase of the flow rate, a negative pressure area will be formed in the gap area between the expansion section 481 and the first contraction section 471, because the increase of the flow rate leads to the decrease of the pressure in this area, so that a pressure difference is formed with the external atmospheric pressure. Since the expansion section 481 is sleeved outside the first contraction section 471, and the expansion section 481 is further provided with the air inlet pipe 487 communicated with the negative pressure area, the external air will be sucked into the foaming pipe 48 and mixed with the water flow, without the need for an additional power source, the air can be sucked in by the power of the water flow itself, thereby saving energy costs. The intermediate section 482 of the foaming pipe 48 is provided with the agent inlet pipe 45 for adding foaming agent. Since the air inlet pipe 487 is arranged upstream of the agent inlet pipe 45, the air is mixed with the water first, and then mixed with the foaming agent, which helps to form more stable and uniform foam, and then the foam is discharged through the spray head 49 to act on the toilet. When the toilet foams, only the first water outlet 331 of the flushing valve 33 needs to be opened, and the water flow reaches the foaming device 42 through the first water outlet 331. Due to the flow of water, a stable negative pressure is first formed in the foaming device 42, air is sucked in under the action of the negative pressure, and then mixed with the foaming agent supplied by the delivery pump body 43. Under the action of the foaming device 42, foam is generated and sprayed from the upper spray opening of the toilet. The foam water is quickly wetted on the entire inner wall of the toilet and accumulates foam at the water seal at the bottom of the toilet, accompanied by the brushing action of the water flow of the upper spray opening.

[0069] In this embodiment, as shown in Figure 5 The agent inlet pipe 45 is provided with an agent adding head 46, and a duckbill valve 451 is arranged between the agent adding head 46 and the agent inlet pipe 45, so that the liquid flows from the agent adding head 46 to the agent inlet pipe 45 in one direction.

[0070] In the above intelligent toilet, the agent inlet pipe 45 communicates with the intermediate section 482, and the inner diameter of the intermediate section 482 is smaller than that of the expansion section 481. When water flows into the intermediate section 482 through the expansion section 481, the flow rate of the water will increase. Since the flow rate of the intermediate section 482 is fast, when the foaming agent enters the agent inlet pipe 45 from the agent adding head 46 and flows to the intermediate section 482, the fast flow rate can cause the liquid to flow back from the intermediate section 482 to the agent adding head 46 or the foaming agent container, thereby possibly contaminating the foaming agent and causing waste. By increasing the duckbill valve 451, when the foaming agent enters the agent inlet pipe 45 from the agent adding head 46, the duckbill valve 451 will open to allow the liquid to pass through; and when the flow rate of the intermediate section 482 is fast and can cause backflow, the duckbill valve 451 will provide sufficient resistance to close to prevent the liquid from flowing in the opposite direction, ensuring that the liquid can only flow from the agent adding head 46 to the agent inlet pipe 45 in one direction, avoiding the risk of backflow.

[0071] In another embodiment, the foaming assembly 4 includes an air pump, and the foaming device 42 is provided with an air inlet pipe 487, and the air outlet of the air pump communicates with the air inlet pipe 487 of the foaming device 42. The air pump can accurately adjust the flow rate of the output gas, deliver the gas to the foaming device 42, mix the gas with water and foaming agent, and help to form more stable and uniform foam. Moreover, the air pump is less affected by external factors, and can still stably deliver gas in the case of unstable water pressure or large changes in water flow rate.

[0072] Embodiment 7

[0073] Based on Embodiment 6, in the intelligent toilet, a spoiler 484 is arranged in the tail section 483 of the foaming pipe 48. The tail section 483 is located downstream of the intermediate section 482 and the expansion section 481. By arranging the spoiler 484 in the tail section 483, the mixture of foaming agent, water and air is fully mixed to change the direction and uneven distribution of the speed, causing vortexes and turbulence in the fluid, which greatly increases the contact area between water, foaming agent and air, so that they can be more fully mixed together. This strong mixing effect can ensure that the foaming agent is uniformly dispersed in the water, and at the same time, the air can also be more uniformly dissolved or dispersed in the water, thereby forming a more delicate and uniform foam, so that the intelligent toilet produces more abundant and delicate foam when flushing, which can better cover the surface of the toilet bowl, prevent water from splashing, suppress odors, etc., thereby optimizing the user's experience.

[0074] In another embodiment, as Figure 5As shown, the foaming pipe 48 comprises a middle section 482 and a tail section 483 with an inner diameter larger than that of the middle section 482, and a spoiler 484 is arranged between the middle section 482 and the tail section 483. The spoiler 484 comprises an inner pipe 485 and support ribs 486 fixed to the outer wall of the inner pipe 485 in the circumferential direction. The support ribs 486 are connected to the inner wall of the foaming pipe 48. The outer diameter of the inner pipe 485 is smaller than the inner diameter of the middle section 482. One end of the inner pipe 485 extends into the middle section 482, and the other end of the inner pipe 485 is arranged in the tail section 483. The space in the inner pipe 485 forms a first flow channel 4851, and the space between the outer wall of the inner pipe 485 and the inner wall of the foaming pipe 48 forms a second flow channel 4852.

[0075] As shown in Figure 9 and 10 , the spoiler 484 comprises an inner pipe 485 and support ribs 486 fixed to the outer wall of the inner pipe 485 in the circumferential direction. The support ribs 486 abut against the inner wall of the foaming pipe 48 to stabilize the spoiler 484 in the foaming pipe 48. The inner pipe 485 extends through the middle section 482 and the tail section 483 of the foaming pipe 48. The outer diameter of the inner pipe 485 is smaller than the inner diameter of the middle section 482, so that two different flow channels are formed in the spoiler 484. The space in the inner pipe 485 forms a first flow channel 4851, and the space between the outer wall of the inner pipe 485 and the inner wall of the foaming pipe 48 forms a second flow channel 4852. When the mixed water flow of water, air and foaming agent passes through the spoiler 484, a first turbulence is formed by the impact at the head of the spoiler 484, and a first foaming is generated. The mixed water flow continues to pass through the spoiler 484. Part of the mixed water flow passes through the inner pipe 485, and part of the mixed water flow passes through the support ribs 486 and then passes through the outer wall of the inner pipe 485 and the inner wall of the tail section 483 of the foaming pipe 48 to form a second turbulence, and a second foaming is generated. The mixed water flow continues to flow. When the mixed water flow passing through the support ribs 486 and the outer wall of the inner pipe 485 enters the tail section 483, the diameter of the outlet of the spoiler 484 is larger than that of the inlet due to the second turbulence. Therefore, under the combined action of the above conditions, the flow rate of the first flow channel 4851 is greater than that of the second flow channel 4852. Due to the difference in flow rate, a transition flow is formed at the outlet of the spoiler 484, and a third foaming is generated. The three times of foaming significantly improves the foaming effect.

[0076] As preferred, the cross-sectional area at the inlet of the first flow channel 4851 is smaller than the cross-sectional area at the outlet of the first flow channel 4851, the cross-sectional area at the inlet of the second flow channel 4852 is equal to the cross-sectional area at the outlet of the second flow channel 4852; or, the cross-sectional area at the inlet of the first flow channel 4851 is smaller than the cross-sectional area at the outlet of the first flow channel 4851, the cross-sectional area at the inlet of the second flow channel 4852 is greater than the cross-sectional area at the outlet of the second flow channel 4852. When the cross-sectional area at the inlet of the first flow channel 4851 is smaller than the cross-sectional area at the outlet of the first flow channel 4851 while the cross-sectional area at the inlet of the second flow channel 4852 is equal to the cross-sectional area at the outlet of the second flow channel 4852, the flow rate at the inlet of the first flow channel 4851 is greater than the flow rate at the outlet of the first flow channel 4851, and such a flow rate difference can make the mixed water flow better foamed; when the cross-sectional area at the inlet of the first flow channel 4851 is smaller than the cross-sectional area at the outlet of the first flow channel 4851 while the cross-sectional area at the inlet of the second flow channel 4852 is greater than the cross-sectional area at the outlet of the second flow channel 4852, the flow rate at the inlet of the first flow channel 4851 is smaller than the flow rate at the outlet of the first flow channel 4851, both of which are to make the mixed water flow more delicate by manufacturing a flow rate difference, and in the present embodiment, only the two ways are taken as a reference.

[0077] In the above intelligent toilet, the flow disturbing member 484 includes a support rib 486 fixed circumferentially to the outer wall of the inner pipe 485, and the support rib 486 is connected with the inner wall of the foaming pipe 48, so that the flow disturbing member 484 can stably abut against the inner wall of the foaming pipe 48, ensuring the stability of the position of the flow disturbing member 484 and preventing displacement or falling off. The plurality of support ribs 486 increase the contact area with the inner wall of the foaming pipe 48, which not only enhances the stability of the flow disturbing member 484, but also increases the flow disturbing area of the mixed liquid during flowing, so that the liquid receives a larger disturbance when passing through the flow disturbing member 484, which helps to generate more bubbles and uniformly set the support ribs 486 to ensure that the mixed water flow remains uniform when flowing out, avoiding the problem of uneven mixing caused by too fast or too slow local flow rate.

[0078] The above is only a preferred embodiment of the present application, and does not limit the present application in any way. Any simple modification, change or equivalent structural transformation of the above embodiment according to the technical essence of the present application still falls within the protection scope of the technical solution of the present application.
