Description

Technical Field

[0001] The utility model relates to the technical field of lighting cleaning, in particular to a self-cleaning device for a lamp tube. Background Art

[0002] Ultraviolet lamps are usually made of ultraviolet-transparent glass or quartz glass. Ultraviolet rays are transmitted through the glass. In terms of air disinfection or gas deodorization, such ultraviolet lamps can be used alone or with ultraviolet-transparent sleeves (which can be quartz, ultraviolet-transparent glass, Teflon and other ultraviolet-transparent materials). After a period of use, dust, dirt and other obstructions will adhere to the outer wall of the ultraviolet lamp tube (including: tube body or sleeve), affecting the output of ultraviolet rays, thereby affecting its sterilization, deodorization and other performance.

[0003] In the past, the common method was periodic manual scrubbing. However, this was inefficient and costly. Therefore, the prior art proposed a "self-cleaning UV lamp module" (patent application number 202222579335.6). This module primarily uses a servo motor to drive a lead screw, which in turn drives a push plate along a slide rod. This, in turn, drives a cleaning ring on the push plate to move back and forth across the UV lamp, automatically cleaning the UV lamp.

[0004] However, in the existing technical solutions similar to the above, since the reciprocating mechanism adopts an exposed screw linkage solution, if the mechanism is in a harsh environment, dirt is easily attached to the screw, causing damage to the thread, resulting in misalignment and jamming of the screw nut, and other problems. Therefore, the reliability needs to be improved. Utility Model Content
