The filter chamber 3 intercepts suspended particles in the air, and the lower layer is provided with an air supply component 5 and an ion treatment chamber 6. The air supply component 5 causes air to flow, and the photocatalytic chamber 403 and the ion treatment chamber 6 of the treatment component 4 perform sterilization treatment on the flowing air. Multiple sets of photocatalytic filters and ultraviolet lamps are arranged alternately in the photocatalytic chamber 403.
[0026] The processing component 4 includes an air inlet pipe 401, an ozone generator 402, and a photocatalytic chamber 403 disposed on the upper surface of the partition 2. The air inlet pipe is connected to the ozone generator 402 through an air nozzle, and the air inlet pipe 401 is connected to the photocatalytic chamber 403. The ozone generator 402 and the photocatalytic chamber 403 perform sterilization treatment on the supplied air.
[0027] As can be seen from the above, the operation of the air supply component 5 allows air to enter through the air intake pipe 401, and then pass through the photocatalytic chamber 403, the air supply component 5, and the ion treatment chamber 6 in sequence. When the air passes through the air intake pipe 401, the ozone generator 402 delivers ozone to the air intake pipe 401. The ozone oxidizes and decomposes bacteria, viruses, and other microorganisms in the air. When the air passes through the photocatalytic chamber 403, the photocatalytic chamber 403 decomposes bacteria and viruses in the air. When the air passes through the ion treatment chamber 6, the ion treatment chamber 6 removes various pollutants from the air.
[0028] Example 2
[0029] As attached Figure 3 As shown, this embodiment is basically the same as the previous embodiment, except that a filter screen 7 is fixed on the upper surface of the filter chamber 3. The filter screen 7 enables the filter chamber 3 to intercept suspended particles in the air. The filter chamber 3 is connected to the air intake pipe 401 and an on / off valve 8 is provided at the connection. The filtered air enters the air intake pipe 401 from the filter chamber 3. The air intake pipe 401 is connected to the ozone generator 402 through an air nozzle. The ozone generator 402 delivers ozone to the air intake pipe 401 for preliminary disinfection.
[0030] As attached Figure 2 and attached Figure 4As shown, specifically, the air supply assembly 5 includes a first pipe 501, a fan 502 and a second pipe 503, the first pipe 501 is in communication with the filter chamber 3, when the on-off valve 8 closes the communication between the filter chamber 3 and the air inlet pipe 401, the air flows to the fan 502 through the first pipe 501, the first pipe 501 passes through the partition 2 from the upper layer to the lower layer and is connected with the fan 502, the fan 502 is connected with the second pipe 503, the second pipe 503 is in communication with the ion treatment chamber 6, the air flows to the ion treatment chamber 6 through the second pipe 503.
[0031] As shown in the accompanying drawings Figure 2 and the accompanying drawings Figure 4 As shown, further, the partition 2 is provided with a through slot, and a tee 9 is arranged in the through slot, a first end of the tee 9 is in communication with the photocatalytic chamber 403, a second end of the tee 9 is in communication with the first pipe 501, and a third end of the tee 9 is in communication with the second pipe 503, and the air can be guided to different areas through the tee 9.
[0032] As shown in the accompanying drawings Figure 4 As shown, further, a first tee valve 10 is arranged at the communication between the second end of the tee 9 and the first pipe 501, and a second tee valve 11 is arranged at the communication between the third end of the tee 9 and the second pipe 503, the first tee valve 10 and the second tee valve 11 are controlled by a rotating controller to control the opening and closing directions, thereby controlling the flow direction of the air.
[0033] From the above, it can be seen that the present application has three working modes:
[0034] I. Open the on-off valve 8, so that the air can flow from the filter chamber 3 to the air inlet pipe 401, at the same time, the first tee valve 10 closes the direction of the first pipe 501 to the filter chamber 3, and the second tee valve 11 closes the direction of the second pipe to the tee 9, so as to ensure the flow direction of the air, the fan 502 makes the air enter the filter chamber 3, the filter screen 7 intercepts the suspended matter in the air, the air enters the air inlet pipe 401 from the filter chamber 3, the ozone generator 402 delivers ozone to the air inlet pipe 401 for sterilization, then the air passes through the photocatalytic chamber 403, the tee 9, the first pipe 501, the fan 502, the second pipe 503 and the ion treatment chamber 6 in turn, and in the process, the ion treatment chamber 6, the ozone generator 402, the photocatalytic chamber 403 and the ion treatment chamber 6 perform disinfection and sterilization treatment on the air, the treated air can be normally discharged, or can be mixed with water after increasing the ozone content, and used for flushing the toilet bowl;
[0035] 2. Close the on / off valve 8 to allow air to flow from the filter chamber 3 to the first pipe 501. At the same time, the first three-way valve 10 closes the direction from the first pipe 501 to the three-way pipe 9, and the second three-way valve 11 closes the direction from the second pipe to the ion treatment chamber 6, ensuring the direction of air flow. The fan 502 causes the air to pass through the filter chamber 3, the first pipe 501, the fan 502, the second pipe 503, the three-way pipe 9, the photocatalytic chamber 403, and the air inlet pipe 401 in sequence. The air passes through the three-way pipe 9 and then through the photocatalytic chamber 403 for disinfection. The ozone generator 402 injects ozone into the air inlet pipe 401 through the nozzle. The treated air flows from the air inlet pipe 401 to the external pipe. The end of the external pipe is equipped with a positive pressure air valve and is installed in the toilet bowl. The treated air finally reaches the vicinity of the toilet bowl for deodorization and disinfection.
[0036] 3. The air valve is equipped with an infrared sensor switch. When a passerby approaches the toilet, the air valve opens and the fan 502 starts working. At the same time, the first three-way valve 10 closes the direction from the first pipe 501 to the filter chamber 3, and the second three-way valve 11 closes the direction from the second pipe to the three-way pipe 9, ensuring the airflow. The odor enters the air intake pipe 401 through the external pipe, and passes through the photocatalytic chamber 403, the three-way pipe 9, the first pipe 501, the fan 502, the second pipe 503, and the ion treatment chamber 6 in sequence. Along the way, the ion treatment chamber 6, the ozone generator 402, the photocatalytic chamber 403, and the ion treatment chamber 6 disinfect the air. The treated air is then discharged from the ion treatment chamber 6.
[0037] Example 3
[0038] As attached Figure 3 As shown, this embodiment is basically the same as the previous embodiment, except that the ion treatment chamber 6 is connected to an exhaust pipe 12, which delivers ozone-laden air to a designated location. The ion treatment chamber 6 is connected to the ozone generator 402 via an air nozzle, which can replenish the ozone and thus adjust the ozone concentration.
[0039] As can be seen from the above, the ozone generator 402 adds ozone to the ion treatment chamber 6 through the air nozzle, thereby adjusting the ozone concentration. The air outlet pipe 12 injects ozone-laden air into the water tank equipped with the air-water mixer through the extension pipe. The air-water mixer fully mixes the gas and water, so that the water in the tank contains ozone for flushing. The ozone-containing water has a sterilizing and disinfecting effect on the toilet. When ozone water is prepared using the first working mode, since the ozone has sufficient time to combine with the air and water, only the ozone generator 402 needs to work, and the photocatalytic chamber 403 and the ion treatment chamber 6 do not need to work.
