[0001] This application relates to the field of toilet technology, and in particular to a sterilization device and a toilet. Background Technology

[0002] As people place increasing emphasis on hygiene and health, smart toilets are gradually becoming more high-tech, and products using ultraviolet (UV) lamps for sterilization and deodorization are becoming more common. However, when using UV irradiation, the complex structure of the toilet bowl means that some corners cannot effectively receive UV light, resulting in poor sterilization effects. Utility Model Content

The plasma generating assembly includes a plasma generating end located in the air duct, upstream of the heating device.

[0005] In one or more of the above optional embodiments, the fan is located in the air duct, the air outlet of the fan is oriented towards the heating device, and the plasma generating end is located in the part of the air duct between the air outlet of the fan and the heating device.

The housing 1 has an air duct A, which has an inlet A1 and an outlet A2. The fan 2 is located in the housing 1 and drives the airflow along the inlet A1 to the outlet A2. The heating device 3 is located in the air duct A and heats the airflow within the air duct A. The plasma generating assembly 4 includes a plasma generating end 41, which is located in the air duct A and upstream of the heating device 3.

[0027] When the sterilization mode is activated, the plasma generating component 4 and the fan 2 work simultaneously. The plasma generating end 41 releases plasma in the air duct A. The fan 2 drives the airflow in the air duct A to flow through the plasma generating end 41. The airflow carries the plasma and is discharged from the outlet A2 of the air duct A for sterilization of the toilet.

[0028] The sterilization device 100 provided in this application embodiment releases plasma in the air duct A by setting a plasma generating end 41. The airflow driven by the fan 2 carries the plasma and is discharged from the outlet A2 of the air duct A for sterilization. Compared with the prior art of using ultraviolet lamp irradiation, the airflow carrying plasma is more likely to reach the dead corners inside the toilet seat than ultraviolet light, which is conducive to improving the sterilization effect on the toilet. On the other hand, the plasma generating end 41 is located upstream of the heating device 3. Compared with the plasma generating end 41 being located downstream of the heating device 3, it is beneficial to reduce the problem of damage to the plasma generating end 41 caused by the airflow after being heated by the heating device flowing through the plasma generating end 41 for a long time.

[0029] In some embodiments, the sterilization device 100 includes a drying mode. When the drying mode is activated, the heating device 3 and the fan 2 work simultaneously. The fan 2 drives the airflow in the air duct A to flow through the heating device 3, and after being heated by the heating device 3, it is discharged from the outlet A2 of the air duct A for drying the toilet.
