[0014] In the above technical solution, the flushing pump controls the opening and closing of the water path. When flushing is needed, the flushing pump draws water from the water tank to the foaming device. The water will first enter the foaming device, and then the foaming agent will enter the foaming device to mix with the water to form foam, which is discharged through the first nozzle. The flushing pump can provide a relatively stable water pressure, thereby ensuring the stability of the water flow during the foaming process to improve the foaming quality.

The flow direction of the water flow can be switched by controlling the valve to meet different cleaning needs. The foaming device is installed in the water path of the upper nozzle and shares the nozzle with the upper nozzle. When the flow path switching valve is switched to the upper nozzle, the foaming device can work simultaneously to spray foam together with the water flow. Under the driving of the flushing pump, the foam is discharged at a very fast speed. This fast discharge speed ensures that the foam can quickly cover the inner wall of the toilet bowl, achieving the effect of rotating and wetting the wall. Rotating and wetting the wall not only helps to clean the toilet bowl, but also reduces the adhesion of stains.

When the foam flushing is performed, the flushing valve controls the first water outlet to be opened, the pressure pump pressurizes the water flow, and the water flow and the foaming agent are fully mixed and then quickly sprayed from the upper nozzle. The rapid foaming speed ensures that the foam can quickly cover the inner wall of the toilet bowl, achieving the effect of rotating and moisturizing the wall, thereby improving the cleaning ability. When the clean water flushing is performed, the flushing valve controls the second water outlet to be opened, and the clean water is quickly sprayed from the lower nozzle under the driving of the pressure pump, thereby improving the cleaning ability.

It can be understood that the detachable connection between closestool cover assembly 8 and closestool base 1 can be achieved by thread connection or clamping commonly used in the art.

[0039] In the above intelligent toilet, by setting the agent adding port 7, opening the entire toilet cover assembly 8 to add agent to the agent supply assembly can be avoided, thereby improving the convenience of use; the main function of the agent plug 5 is to seal the agent adding port 7 to prevent liquid leakage or external pollutants from entering the agent supply assembly. When agent needs to be added, the user can open the agent plug 5 and add the foaming agent to the agent supply assembly through the agent adding port 7; after adding the agent, the agent plug 5 is used to close the agent adding port 7, and the overall sealing is completed.

[0040] Further, the toilet cover assembly 8 further includes a decorative cover 6 placed on the cover body 81 to shield the agent adding port 7, making the whole machine more beautiful.

[0041] Further, as shown in Figure 1 the agent supply assembly includes an agent tank 41 and a delivery pump body 43, the agent tank 41 is installed on the bottom plate 82 and is fixed on the bottom plate 82 to ensure its stability, the agent tank 41 adopts a semi-open structure, the cover body 81 is closed on the bottom plate 82 to complete the overall sealing of the agent tank 41, the agent adding port 7 is arranged at a position corresponding to the agent tank 41 on the cover body 81, which facilitates the user to add or supplement the foaming agent in the agent tank 41, the delivery pump body 43 is installed on the bottom plate 82, the input end of the delivery pump body 43 is communicated with the agent tank 41 through a hose, and the joint assembly 2 is arranged between the output end of the delivery pump body 43 and the agent inlet pipe 45.

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.

[0043] Embodiment 2

[0044] Based on Embodiment 1, as shown in Figures 1 to 4 In the intelligent toilet, the flushing device 3 includes a water tank assembly, a flushing pump 32, and a first nozzle 35. The pump-in end of the flushing pump 32 communicates with the water tank assembly, the pump-out end of the flushing pump 32 communicates with the foaming device 42, and the first nozzle 35 communicates with the foaming device 42. The flushing pump 32 draws water from the water tank to the foaming device 42. When flushing is needed, water will first enter the foaming device 42, and then the foaming agent will enter the foaming device 42 to mix with the water to form foam, which is discharged through the first nozzle 35. The flushing pump 32 controls the opening and closing of the water path. When flushing is needed, the flushing pump 32 draws water from the water tank assembly to the foaming device 42. Water will first enter the foaming device 42, and then the foaming agent will enter the foaming device 42 to mix with the water to form foam, which is discharged through the first nozzle 35. The flushing pump 32 can provide a relatively stable water pressure, thereby ensuring the stability of the water flow during the foaming process to improve the foaming quality.

[0045] Further, the flushing device 3 further comprises a flow switching valve 33 and a lower nozzle 34, the first nozzle 35 being an upper nozzle, the flow switching valve 33 being arranged between the pump outlet end of the flushing pump 32 and the foaming device 42, the pump outlet end of the flushing pump 32 being in communication with the flow switching valve 33 through a pipeline, the lower nozzle 34 being in communication with the flow switching valve 33 through a pipeline, the foaming device 42 being in communication with the flow switching valve 33, the upper nozzle being installed at an upper position in the toilet base 1, and the lower nozzle 34 being installed at the bottom of the toilet base 1. The water tank assembly, the flushing pump 32, the flow switching valve 33, the first nozzle 35, and the lower nozzle 34 are sequentially connected through a hose, and the flow switching valve 33 is used to switch the water flow to the upper nozzle and the lower nozzle 34 to complete the flushing function.

[0046] In the above-mentioned intelligent toilet, the flow switching valve 33 is arranged between the pump outlet end of the flushing pump 32 and the foaming device 42, the flow switching valve 33 has two outlets, one connected to the upper nozzle and the other connected to the lower nozzle 34, and the water flow direction can be switched by controlling the valve to meet different cleaning needs. The foaming device 42 is installed in the waterway of the upper nozzle and shares the nozzle with the upper nozzle, and when the flow switching valve 33 is switched to the upper nozzle, the foaming device 42 can work simultaneously to spray foam together with the water flow, and under the driving of the flushing pump 32, the foam has a very fast outflow speed. This fast outflow speed ensures that the foam can quickly cover the inner wall of the toilet bowl to achieve the effect of rotating and moistening the wall. Rotating and moistening the wall not only helps to clean the toilet bowl, but also reduces the adhesion of stains.

[0047] Further, as shown in Figure 4 the foaming device 42 comprises a connecting head 47, a foaming pipe 48, and a nozzle 49 connected and communicated in sequence, 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 formed 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 in communication with the negative pressure area, and the agent inlet pipe 45 is arranged in the intermediate section 482. 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 to enable the foaming agent to flow unidirectionally from the agent adding head 46 to the agent inlet pipe 45.

[0048] When the water flow passes through the first contraction section 471 of the connector 47 and enters the expansion section 481 of the foaming pipe 48, due to the increase of the flow rate, a negative pressure area is 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, thereby forming a pressure difference with the external atmospheric pressure. Since the expansion section 481 is sleeved outside the first contraction section 471, and the air inlet pipe 487 is also arranged on the expansion section 481 and communicates with the negative pressure area, the external air will be sucked into the foaming pipe 48 and mixed with the water flow. Without an additional power source, the air is sucked by the power of the water flow itself, thereby saving energy costs. The middle 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. The agent inlet pipe 45 communicates with the middle section 482, and the inner diameter of the middle section 482 is smaller than that of the expansion section 481. When the water flows into the middle section 482 through the expansion section 481, the flow rate of the water will increase. Since the flow rate of the middle section 482 is fast, when the foaming agent enters the agent inlet pipe 45 from the agent adding head 46 and flows to the middle section 482, the fast flow rate may cause the liquid to flow back from the middle 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; when the flow rate of the middle section 482 is fast and may cause backflow, the duckbill valve 451 will provide sufficient resistance to close to prevent the liquid from flowing in the reverse direction, thereby ensuring that the liquid can only flow from the agent adding head 46 to the agent inlet pipe 45 in one direction, and avoiding the risk of backflow.

The flushing valve 36 is provided with two independent on-off control structures, which can control the opening and closing of the first water outlet 361 and the second water outlet 362, so as to control the opening and closing of water and the flow direction of water, so that the intelligent toilet can rely on the foam water flow of the upper nozzle and the tap water of the lower nozzle 34 to cooperatively complete the multi-directional flushing function.

[0056] When the water flow passes through the first contraction section 471 of the connector 47 into the expansion section 481 of the foaming pipe 48, due to the increase of the flow rate, the gap area between the expansion section 481 and the first contraction section 471 will form a negative pressure area, because the increase of the flow rate causes the pressure of the area to decrease, thereby forming a pressure difference with the external atmospheric pressure, since the expansion section 481 is sleeved outside the first contraction section 471, and the expansion section 481 is also provided with an air inlet pipe 487 which is in communication with the negative pressure area, so 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 middle section 482 of the foaming pipe 48 is provided with an 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. The agent inlet pipe 45 is in communication with the middle section 482, and the inner diameter of the middle section 482 is smaller than that of the expansion section 481, when the water flows into the middle section 482 through the expansion section 481, the flow rate of the water will increase, since the flow rate of the middle section 482 is fast, when the foaming agent enters the agent inlet pipe 45 from the agent adding head 46 and flows to the middle section 482, the fast flow rate may cause the liquid to flow back from the middle 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; when the flow rate of the middle section 482 is fast and may 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.

[0057] Example 4

[0058] Based on Example 1, in the intelligent toilet, such as Figure 6As shown, the flushing device 3 comprises a flushing valve 36, a first spout 35, a pressurizing pump 37 and a lower spout 34. The flushing valve 36 comprises a valve water inlet 363, a first water outlet 361 and a second water outlet 362 with switch control structure. The valve water inlet 363 is the water inlet of the flushing valve 36, which is communicated with the external water source through pipeline. The first water outlet 361 is communicated with the water inlet of the foaming device 42 through a hose. The first spout 35 is directly connected and communicated with the water outlet of the foaming device 42. The first spout 35 is an upper spout, which is installed on the upper side of the toilet seat 1. The lower spout 34 is installed at the bottom of the toilet seat 1. The pressurizing pump 37 is arranged between the water inlet of the flushing valve 36 and the external water source. The pressurizing pump 37 comprises a pump water inlet 371, which is the water inlet of the pressurizing pump 37, and is communicated with the external water source through pipeline. The water outlet of the pressurizing pump 37 is directly connected and communicated with the water inlet of the flushing valve 36, and they are sealed by an O-ring. In the above-mentioned intelligent toilet, when the intelligent toilet is flushing and foaming, the pressurizing pump 37 is started synchronously to pressurize the water inlet, so as to avoid the situation that the water pressure of the tap water is insufficient, thereby optimizing the effect of flushing and foaming. When there is no need to flush, the first water outlet 361 and the second water outlet 362 can be closed, so as to avoid the waste of water resources. When the foam flushing is performed, the flushing valve 36 controls the first water outlet 361 to be opened, and the pressurizing pump 37 pressurizes the water flow, so that the water flow is fully mixed with the foaming agent and then quickly sprayed from the upper spout. The rapid foaming speed ensures that the foam can quickly cover the inner wall of the toilet bowl, so as to achieve the effect of revolving and wall moistening, and improve the cleaning ability. When the clean water flushing is performed, the flushing valve 36 controls the second water outlet 362 to be opened, and the clean water is quickly sprayed from the lower spout 34 under the driving of the pressurizing pump 37, so as to improve the cleaning ability.

[0059] Further, as shown in the figure, Figure 4 The foaming device 42 comprises a connecting head 47, a foaming pipe 48 and a spray head 49 which are sequentially connected and communicated. The connecting head 47 is provided with a first contraction section 471. The foaming pipe 48 comprises an expansion section 481, an intermediate section 482 and a tail section 483 which are sequentially communicated from upstream to downstream. The expansion section 481 is sleeved outside the first contraction section 471. A gap is formed between the inner wall of the expansion section 481 and the outer diameter of the first contraction section 471, and a negative pressure area is formed. The expansion section 481 is provided with an air inlet pipe 487 which is communicated with the negative pressure area. The agent inlet pipe 45 is arranged in the intermediate section 482. The agent inlet pipe 45 is provided with an agent adding head 46. A duckbill valve 451 is arranged between the agent adding head 46 and the agent inlet pipe 45, so that the foaming agent flows from the agent adding head 46 to the agent inlet pipe 45 in one direction.

[0060] When the water flow passes through the first contraction section 471 of the connector 47 and enters the expansion section 481 of the foaming pipe 48, 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, thus forming a pressure difference with the external atmospheric pressure. Since the expansion section 481 is sleeved outside the first contraction section 471, and the expansion section 481 is also provided with an air inlet pipe 487 which is in communication with the negative pressure area, the external air will be sucked into the foaming pipe 48 and mixed with the water flow. Without an additional power gas source, the air suction is realized by the power of the water flow itself, thereby saving energy cost. The middle section 482 of the foaming pipe 48 is provided with an 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. The agent inlet pipe 45 is in communication with the middle section 482, and the inner diameter of the middle section 482 is smaller than that of the expansion section 481. When the water flows into the middle section 482 through the expansion section 481, the flow rate of the water will increase. Since the flow rate of the middle section 482 is fast, when the foaming agent enters the agent inlet pipe 45 from the agent adding head 46 and flows to the middle section 482, the fast flow rate may cause the liquid to flow back from the middle 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. When the flow rate of the middle section 482 is fast and may cause backflow, the duckbill valve 451 will provide sufficient resistance to close to prevent the liquid from flowing in the reverse direction, thereby ensuring that the liquid can only flow from the agent adding head 46 to the agent inlet pipe 45 in one direction, and avoiding the risk of backflow.

[0062] Based on Example 2, the difference between this embodiment and Example 2 is that a gas supply device is arranged to supply gas. Specifically, the foaming assembly 4 comprises a gas pump, and the foaming device 42 is provided with an air inlet pipe 487, and the gas outlet of the gas pump is in communication with the air inlet pipe 487 of the foaming device 42. The gas pump can accurately adjust the flow rate of the output gas, and deliver the gas to the foaming device 42, so that the gas is mixed with the water and the foaming agent, which helps to form more stable and uniform foam, and the gas pump is less affected by external factors. In the case of unstable water pressure or large change of water flow rate, the gas can still be stably delivered.
