Detailed Description

Referring to fig. 1 to 8, an intelligent toilet includes a ceramic base 10, a dirt groove 12 is formed in a front portion of the ceramic base, a flushing water channel 14 is formed in a rear side of an upper portion of the dirt groove of the ceramic base, a sewage discharge pipeline 16 is formed in a rear side of a lower portion of the dirt groove of the ceramic base, and a flushing system 20 is installed in a rear portion of the ceramic base, so that the dirt groove 12 of the ceramic base can be flushed through the flushing system 20. The flushing channel 14, dirt channel 12 and waste water outlet 16 are conventional structures of ceramic bases for toilets and the structure and operation of the flushing system 20 will be described in detail below with reference to existing ceramic bases.

The flushing system 20 includes a water inlet valve 21 and a water tank 22, the water inlet valve 21 is a water inlet valve with an air blocking function, the water inlet valve 21 cuts off a water inlet path (blocking water supply to the water tank) when a liquid level in the water tank 22 rises to a high water level set value, the water inlet valve opens the water inlet path (supplying water to the water tank) when the liquid level of the water tank falls to a low water level set value, an air blocking interval exists between a water outlet flow path of the water inlet valve 21 and the liquid level rising to the high water level set value, and the air blocking interval means that water is converged with water in the water tank only when falling a certain distance after coming out from the water outlet flow path. The specific structure of the inlet valve 21 is shown in applicant's prior patent 202020261811.8. The top surface of the water tank 22 is provided with a mounting through hole 221, and the water inlet valve 21 is mounted on the top of the water tank through the mounting through hole 221. The flushing system 20 further comprises a water pump 23, the water outlet 222 of the water tank is connected with the water inlet of the water pump 23 through a water pipe 25, and the water outlet of the water pump 23 is connected with the flushing water channel 14 of the ceramic base through a water pipe 26.

When the water needs to be flushed, the water pump 23 is started to pump out the water in the water tank 22, and the water enters the flushing water channel 14 to finally realize flushing. Once the liquid level of the water tank 22 drops to the low level set value, the water inlet valve 21 is automatically opened, an external water source replenishes the water tank 22, and when the water in the water tank 22 rises to the high level set value, the water inlet valve 21 is automatically closed, thereby completing the water replenishing of the water tank 22.

Preferably, the water pump 23 is an impeller-type water pump, and the water pipe 26 is connected to the flush channel 14 at a position higher than the high water level set value. Thus, even if the water pump 23 is not activated, the entire water path is open, and the liquid level of the water tank 22 normally reaches the high level set value, and no water flows out of the flush water path 14 when the water pump 23 is not activated. If the inlet valve 21 fails to close by itself due to a malfunction, i.e., the water tank is always refilled, the side water can flow along the water pipe 25, the water pump 23, the water pipe 26 into the flushing waterway 14, i.e., to the dirt tray 12.

Preferably, the water outlet 222 of the water tank 22 is disposed at the bottom thereof, and the water pump 23 is disposed at the lower portion of the outside of the water tank 22. The water pump 23 is positioned lower, and when water is discharged, the water in the water tank 22 can directly fill the water pump 23, so that the flushing effect can be improved.

Preferably, the water tank 22 is further provided with an overflow port 223, and the height of the overflow port 223 is greater than the high water level set value. The overflow opening can be beneficial to the discharge of air when filling water into the water tank 22 on the one hand, and on the other hand, if the water tank 22 continuously replenishes water, the excessive water can also flow out from the overflow opening. In this embodiment, the height of the overflow port 223 is greater than the height of the connection position between the water pipe 26 and the flushing water channel 14, so that if the water inlet valve 21 cannot be closed by itself, the water tank is continuously filled with water, and more water will enter the flushing water channel 14 and will not flow out from the overflow port 223.

Preferably, the inlet flow path of the inlet valve 21 is hooked on the side wall of the water tank 22, so that the installation and positioning are convenient.

Preferably, the top surface of the water tank 22 is provided with a surrounding barrier 225 around the installation through hole 221.

The intelligent toilet further comprises a bottom plate 30 and a control module 40 used for controlling the water pump 23 to be started and stopped, the bottom plate 30 is connected to the bottom surface of the inner cavity of the rear portion of the ceramic base 10, and the water tank 22, the water pump 23 and the control module 40 are installed on the bottom plate 30.

In this embodiment, the water pipe 26 connected to the flushing water channel 14 is inserted at its end into the inner end of a connector 50, the outer end of the connector 50 extends into the flushing water channel 14 through the mounting hole 18 of the ceramic base 10, and the outer end of the connector 50 is flared to form a rib 52. The joint 50 is sleeved with a rubber part 60, the rubber part 60 penetrates through the mounting hole 18 of the ceramic base, the outer surface of the joint 50 is provided with threads and is screwed with a nut 54, the nut 54 is screwed up to be matched with the rib 52 to extrude the rubber part 60 from the inner side and the outer side, and the rubber part 60 is sealed and clamped with the mounting hole 18 after being expanded. It can be seen that the water pipe 26 can be installed in the installation hole from outside to inside through the joint and the rubber part, then the installation and fixation are realized by screwing the nut, and meanwhile, the rubber part seals the installation hole together, so that the assembly is simple, and the sealing effect is better.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
