Device for automatically spraying disinfectant to sterilize and disinfect escalator

Abstract

The invention discloses a device for automatically spraying a disinfectant to sterilize and disinfect an escalator. The device comprises a transmission control panel, an encoder, a roller, a liquid level detection sensor, an atomizer and a disinfectant container. The roller is tightly attached to a handrail belt of the escalator, when the handrail belt moves, the roller is driven to roll, the roller drives the encoder to rotate; the encoder judges whether the handrail moves or not through rotation and then sends a pulse signal to the transmission control panel; the transmission control panel controls the atomizer to start spraying after detecting that the handrail belt moves and to stop spraying after detecting that the handrail belt stops moving; and the liquid level detection sensor is used for detecting the disinfectant capacity of the disinfectant container and sending a signal to the transmission control panel, and when the disinfectant capacity is lower than a certain numerical value, the transmission control panel gives out an alarm sound through a buzzer to remind maintenance personnel that the disinfectant needs to be added. The device is convenient to install and can be additionally installed on an existing escalator, and the structure of the escalator does not need to be changed.

Description

technical field [0001] The invention relates to a device for sterilization and disinfection, in particular to a device for automatically spraying disinfectant on an escalator for sterilization and disinfection. Background technique [0002] Escalators are widely used in supermarkets, shopping malls and other public places. Most escalators are disinfected every day, but the disinfection method used is generally to wipe the handrail of the escalator with a disposable conventional chemical disinfectant. In addition, the invention uses UV-C ultraviolet lamps to be installed at the circulation of the handrails inside the escalator, and the handrails are irradiated by ultraviolet rays for sterilization and disinfection. [0003] There is following shortcoming in prior art: [0004] a. Disinfection method Use a disposable conventional chemical disinfectant to wipe the handrail of the escalator. The wiping cloth is constantly in contact with the handrail, and the wiping cloth its...

AI Technical Summary

Problems solved by technology

The wiping cloth is constantly in contact with the handrail, and the wiping cloth itself will accumulate a large amount of bacteria after a long period of use, which is likely to cause secondary pollution

[0005] b. There are still deficiencies in the ultraviolet lamp sterilization and disinfection scheme. First, the ultraviolet lamp tube is prone to fouling, which affects the penetration of ultraviolet light and the sterilization effect. Second, some bacteria can repair their damaged tissues with the assistance of light after being inactivated by ultraviolet light. To achieve the purpose of resurrection, and the effect of sterilization will be reduced after the aging of the lamp tube, so it is not easy to be discovered by the staff in time
