The circuit board 3 is fixedly arranged in the shell 11, and a space is formed between the circuit board and the lower bottom cover 13, and the part of the gravity switch 4 protruding out of the circuit board 3 is positioned in the space.

The upper part of the outer shell 11 is also provided with a fragrance dispersing hole 10 communicated with the first containing cavity and used for dispersing fragrance for the perfume bag 1, wherein the outer wrapping film of the perfume bag 1 is a breathable film.

The lower part of the outer shell 11 is provided with a lens 8 for emitting the light of the UVC lamp 5. The material of the lens 8 is preferably quartz glass. The outer face of the lens 8 is also glued to a second annular patch 80, sealing the lens 8 to the housing. So as to protect the second accommodating chamber from water and prevent the circuit board 3 from being corroded by water.

The back of the lower bottom cover 13 is connected with a base 14 buckled with the lower bottom cover 13, one side of the base 14 far away from the lower bottom cover 13 is adhered with a back adhesive 15, and the back adhesive 15 is used for being adhered with the inner side of the toilet cover. The casing can also take off from base 14 and go to charge, and the interface setting that charges is equipped with the opening at the lower extreme of circuit board 3, the relative interface that charges on shell 11. The kneck that charges sets up the waterproof layer, prevents that water from getting into the second and holding the chamber.

The principle of the gravity switch 4 controlling the turning on or off of the UVC lamp 5 will be described below.

The disinfecting and killing device is arranged on the inner side surface of the toilet cover, the gravity switch 4 and the inner side surface of the toilet cover form an inclined included angle which is set to be 45-180 degrees (end points are not included to be 45-180 degrees), for example, the inclined included angle can be set to be 65 degrees, so that when the disinfecting and killing device is switched between an opening state and a closing state, the gravity switch 4 correspondingly turns on or turns off the UVC lamp 5. When the toilet cover is horizontally covered, the conductive small ball in the gravity switch 4 falls on the conductive end due to gravity, the gravity switch 4 conducts a circuit, and the UVC lamp 5 is turned on; when the toilet cover is erected, the erecting angle is generally 135 degrees relative to the toilet surface, the inclined included angle is set to be 45-180 degrees (the included angles do not include 45 degrees and 180 degrees of end points), at the moment, the non-conductive end of the gravity switch 4 is downward certainly, the conductive ball falls on the non-conductive end, and at the moment, the gravity switch closes the electric connection of the UVC lamp 5. The included angle of inclination is preferably 90 to 180 (excluding the end points 90 and 180), for example the included angle of inclination may be set at 115 to accommodate a situation where the angle of erection of the toilet lid is 90 to 135: when the toilet cover is horizontally covered, the UVC lamp 5 is turned on; when the toilet lid is raised, the UVC lamp 5 is turned off. The sterilizing device has simple structure and can effectively kill germs in the toilet.

In one preferred embodiment, the circuit board 3 is approximately parallel to the inner side mounting surface of the toilet lid, and may have an included angle of 5 to 10 degrees, and the circuit board 3 is approximately parallel to the inner side mounting surface of the toilet lid, so that the inner mounting space of the killing device may be saved.
