[0026] By setting two sets of axial flow fans 12, direct current circulation of air in the sterilizer is achieved;

[0027] An inner shell 2 is installed in the middle of the outer shell 1. A group of ventilation holes 3 are opened on both sides of the inner shell 2. The inner top of the inner shell 2 is connected to an upper vibration frame 5 that can reciprocate up and down through a group of elastic reset members a4. The bottom surface of the upper vibration frame 5 is connected to a lower vibration plate 7 that can reciprocate left and right through a group of elastic reset members b6.

[0028] The elastic reset member a4 and the elastic reset member b6 both include a T-shaped guide rod and a reset spring sleeved on the outside of the T-shaped guide rod;

[0029] A transmission assembly is installed on the inner shell 2, and the upper vibration frame 5 and the lower vibration plate 7 are driven by the transmission assembly;

[0030] The transmission assembly includes a motor fixed in the housing 1 and a differential shaft 13 rotatably connected in the housing 1, a first half-missing gear 14 is fixedly mounted on the output shaft end of the motor, and a first toothed plate 15 vertically arranged and transmission-connected to the first half-missing gear is fixedly mounted on the top surface of the upper vibration frame 5;

[0031] The output shaft end of the motor and the differential shaft 13 are both equipped with linkage bevel gears, the two linkage bevel gears mesh with each other, a second half-missing gear 16 is installed on the differential shaft 13, and a second toothed plate 17 meshing with the second half-missing gear 16 is fixedly installed on the surface of the lower vibration plate 7;

[0032] The tooth heights of the second toothed plate 17 and the second half-missing gear 16 are the same as the up-and-down displacement stroke of the upper vibration frame 5, and the differential shaft 13 is vertically arranged;

[0033] The height difference between the teeth of the second toothed plate 17 and the second half-missing gear 16 is set so that the second half-missing gear 16 can continuously drive the second toothed plate 17 during the reciprocating movement of the lower vibration plate 7;

[0034] A group of electrostatic suction plates 8 are installed on the bottom surface of the inner shell 2, a conductive component electrically connected to the electrostatic suction plates 8 is installed on the inner wall of the outer shell 1, and a dust accumulation valve 9 is installed on the bottom surface of the outer shell 1 and at a position corresponding to the position below the electrostatic suction plates 8.

Through the left and right reciprocating movement of one group of electrostatic suction plates 8, the position of one group of electrostatic suction plates 8 is switched. Through the position change of one group of electrostatic suction plates 8, half of the electrostatic suction plates 8 are located in the middle of the ventilation strip holes 3 during operation, and half of the electrostatic suction plates 8 are staggered with the ventilation strip holes 3. When the electrostatic suction plates 8 are located at the position of the ventilation strip holes 3, the electrostatic suction plates 8 are powered on to generate electrostatic adsorption force. When the electrostatic suction plates 8 are located at the position of the non-ventilation strip holes 3, the electrostatic suction plates 8 are powered off and lose adsorption force, and each electrostatic suction plate 8 is cyclically switched between the above two states.

[0043] The electrostatic field generated by the electrostatic suction plate 8 can kill bacteria, viruses and other microorganisms in the air through the electrostatic field, thereby achieving air disinfection, sterilization and dust removal effects;
