The arrangement of the plurality of slide bars 15 can provide good support and guidance for the installation rod 14 , thereby effectively reducing the force on the screw rod 12 .

[0025] After the ultraviolet lamp 10 has been used for a period of time, the second motor 11 can be started to drive the screw rod 12 to rotate, and then the screw rod 12 and the ball nut 13 can cooperate to drive the mounting rod 14 to move along the direction of the slide rod 15, so that the annular brush 16 can slide on the outer wall of the ultraviolet lamp 10, and the dust particles adhered to the outer wall of the ultraviolet lamp 10 can be cleaned by the bristles, thereby maintaining the normal operation of the ultraviolet lamp and greatly improving the stability of the sterilization effect of the sterilizer.

Two purge mechanisms 21 are symmetrically provided on the top and bottom of the inner wall of the square tunnel pipe 1, and the purge mechanism 21 is located between the package inlet 2 and the air outlet pipe 17.

[0031] The purge mechanism 21 includes a wind knife shell 22, the outer wall of the wind knife shell 22 is fixedly connected to the inner wall of the square tunnel pipe 1, an air inlet pipe 23 is penetrated at one end of the wind knife shell 22, the air inlet end of the air inlet pipe 23 penetrates the inner wall of the square tunnel pipe 1 and is fixedly connected to the air outlet end of the external air compressor, an air outlet slit 24 is provided at the bottom of the wind knife shell 22, and an ion rod 25 is fixedly connected to the outer wall of the wind knife shell 22.

When these positive and negative ions are blown to the large package product by the high-speed airflow, they will be neutralized with the positive and negative ions on the outer wall of the large package product, thereby eliminating the static electricity on the surface of the large package product to prevent dust particles from being electrostatically adsorbed on the surface of the product, effectively improving the blowing effect, and the dust particles blown away will be discharged from the air outlet duct 17 through the exhaust fan 18 to achieve the purpose of cleaning the product packaging.
