As shown in fig. 10, the present invention further provides a method for installing a sterilization device, comprising the steps of:
s1, selecting a ventilation air pipe needing to be provided with the disinfection and sterilization device, and selecting a spiral winding ring with matched size according to the size of the ventilation air pipe.
In order to guarantee better result of use, with ventilation duct size and spiral winding size phase-match, ensure that spiral winding and ventilation duct inner wall fully contact, guarantee the stability after the spiral winding installation on the one hand, on the other hand makes the spiral winding scope bigger when carrying out the ultraviolet sterilization disinfection, and the omission appears in the reduction.
And S2, throwing the spiral winding ring into the ventilation air pipe, and fixing one end of the connecting and stretching device on the inner wall of the ventilation air pipe.
And S3, stretching the other end of the connecting and stretching device, completely unfolding the spiral winding ring, fixing the other end of the connecting and stretching device on the inner wall of the ventilation air duct, and switching on the ultraviolet lamp on the spiral winding ring.
According to the disinfection and sterilization device that the spiral winding that treats sterile ventilation tuber pipe 3 selection size matching corresponds, realize fixed mounting through emboliaing the ventilation tuber pipe with spiral winding 1 and cooperate and connect stretching device 2, and easy operation can adapt to different mounted positions, utilize the tensile of connecting stretching device 2 to launch spiral winding 1 after the installation in addition, the convenience realizes the fast assembly and the regulation of whole device in ventilation tuber pipe 3, and keep the stability of whole device, and convenient operation.
Although the embodiments of the present invention have been described in detail hereinabove, it is apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it is to be understood that such modifications and variations are within the scope and spirit of the present invention as set forth in the following claims.
