The air supply pipe transmits the steam to the annular pipe ring, and the annular pipe ring sprays the steam from the spray-disinfection pipe to perform steam disinfection on the seat and the inside of the toilet body. After a certain period of disinfection, the controller controls the three-way solenoid valve to cut off the passage connected to the steam interface, and then opens the passage connected to the high-pressure air interface. Similarly, the high-pressure airflow enters the spray-disinfection pipe from the high-pressure air interface, and then sprays out from the spray-disinfection pipe to dry the steam and water flow on the toilet body and the seat. After drying, the controller controls the three-way solenoid valve to cut off the passage connected to the high-pressure air interface; then the controller controls the ultraviolet lamp to turn on, and the ultraviolet lamp will perform ultraviolet disinfection on the inside of the toilet body and the seat.

[0031] The toilet body 1 is provided with a three-way solenoid valve 6, which is provided with two air inlets and one air outlet, wherein the two air inlets are respectively connected with an air path connector to form a steam interface 11 and a high-pressure air interface 12, and the air outlet of the three-way solenoid valve 6 is connected with an air supply pipe 43 extending to the outside of the toilet cover 3 by a connecting pipe 10; the three-way solenoid valve 6 can control the opening and closing states of the steam interface 11 and the high-pressure air interface 12 respectively (the three-way solenoid valve 6 is a direct application of the present application, not within the protection scope of the present application, and its reference model may be SFQ-20, and the function of the three-way solenoid valve 6 may also be formed by a combination of a three-way valve and two ordinary solenoid valves).

[0032] The connecting pipe 10 is an explosion-proof hose.

[0033] A human body sensor 7 is provided at the lower part of the toilet body 1 away from the toilet cover 3, and a controller 8 is provided on the toilet body 1. The controller 8 is electrically connected to the human body sensor 7 by a wire; the human body sensor 7 is embedded in the toilet body 1, and the three-way solenoid valve 6 and the controller 8 are arranged at the rear of the toilet body 1.

[0034] The bottom and rear side of the toilet body 1 are provided with a wire groove 71 for buckling the wire inside. A sealing strip is arranged in the wire groove 71 to seal the wire between the controller 8 and the human body sensor 7 in the wire groove 71.

[0035] The power connection end of the three-way solenoid valve 6 is electrically connected to the control end of the controller 8 using a wire, the flushing valve of the toilet body 1 uses a solenoid valve (the flushing valve of the toilet body 1 is not shown in the figure), the flushing valve of the toilet body 1 is electrically connected to the control end of the controller 8 using a wire, and the circuits of all ultraviolet lamps 5 connected in parallel are electrically connected to the controller 8.

[0036] The spray-extinguishing mechanism 4 is covered with a protective cover 9, which is respectively provided with a pipe ring embedded groove 91 and a nozzle reserved groove 92 for hiding the embedded annular pipe ring 41 and the spray-extinguishing pipe 42. The outer side of the nozzle reserved groove 92 extends to the outside of the protective cover 9, so that a nozzle 93 connected to the spray-extinguishing pipe 42 is formed on the surface of the protective cover 9, and the outer contour of the protective cover 9 is smaller than the inner contour of the seat ring 2.

[0037] Two sets of locking rods 21 with screw structures are provided under the seat ring 2, and corresponding positions of the toilet body 1 are provided with locking holes 13 for the locking rods 21 to penetrate.

[0038] The toilet cover 3 is provided with two groups of pads 31 with round convex structures inside near its hinge side. When the toilet cover 3 is closed, the pads 31 are arranged between the toilet cover 3 and the seat ring 2, so that the seat ring 2 and the toilet cover 3 form a hollow interlayer. The establishment of the hollow interlayer prevents the ultraviolet lamp 5 from being directly attached to the seat ring 2, and the ultraviolet lamp 5 can emit ultraviolet light to disinfect the toilet seat.

[0039] At least one set of pressure sensors 23 is provided between the seat ring 2 and the toilet body 1; the pressure sensor 23 is electrically connected to the controller 8 (when the pressure sensor 23 is in use, the locking nut 22 is not tightened, and space is reserved for the pressure sensor 23 to sense and reset).

[0040] Brief description of the usage process:

[0041] When in use, the toilet is installed and fixed, the steam interface 11 is connected to an external steam pipeline, the high-pressure air interface 12 is connected to an external compressed air pipeline, and the controller 8 is powered on. The controller 8 supplies power to the ultraviolet lamp 5, the three-way solenoid valve 6, and the human body sensor 7 and controls their operation (the controller 8 is designed using an existing circuit development board, and its specific structure and specific working principle are not within the scope of protection of this application, so its specific structure and control principle are omitted).

[0042] When the user goes to the toilet, he opens the closed toilet lid 3, sits on the seat 2 and goes to the toilet body 1. After the pressure sensor 23 detects that the weight on the seat 2 is greater than 10KG, it is determined that someone is using the toilet. The pressure sensor 23 transmits this signal to the controller 8. After receiving this signal, the controller 8 enters the disinfection preparation. At this time, the controller 8 starts the human body sensor 7 to detect the user's leaving at any time; the protective cover 9 provides anti-bumping protection when the user goes to the toilet.

[0043] After using the toilet, the user directly closes the toilet lid 3 and leaves the toilet body 1. The human body sensor 7 on the toilet body 1 detects that the human body has left and sends an instruction to the controller 8. After 5-10 seconds, the controller 8 opens the flush valve of the toilet body 1 and flushes the inside of the toilet body 1. After flushing 1-3 times, the controller 8 controls the three-way solenoid valve 6 to open the passage connected to the steam interface 11. The steam of the steam interface 11 is transported to the air supply pipe 43 by the connecting pipe 10. The air supply pipe 43 transfers the steam to the annular pipe ring 41. The annular pipe ring 41 sprays the steam from the spray pipe 42 to steam disinfect the seat ring 2 and the inside of the toilet body 1. After a certain period of disinfection, the controller 8 controls the three-way solenoid valve 6 to cut off the passage connected to the steam interface 11, and then open the passage connected to the high-pressure air interface 12. Similarly, the high-pressure airflow enters the spray pipe 42 from the high-pressure air interface 12, and then sprays out from the spray pipe 42 to dry the steam water flow on the toilet body 1 and the seat ring 2.

[0044] After drying is completed, the controller 8 controls the three-way solenoid valve 6 to cut off the passage connected to the high-pressure air interface 12; then the controller 8 controls the ultraviolet lamp 5 to turn on, because the pad 31 is set up when the toilet cover 3 is closed, the pad 31 is set between the toilet cover 3 and the seat ring 2, so that the seat ring 2 and the toilet cover 3 form a hollow interlayer, and the establishment of the hollow interlayer prevents the ultraviolet lamp 5 from being directly attached to the seat ring 2, and the ultraviolet lamp 5 can emit ultraviolet light to the seat ring 2; therefore, the working ultraviolet lamp 5 will perform ultraviolet disinfection on the inside of the toilet body 1 and the seat ring 2. After the irradiation is turned off, the controller 8 cuts off the circuit of the human body sensor 7 ultraviolet lamp 5 and waits for the next user to use the toilet.

[0045] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
