need not to adopt electronic structure, need not to connect the electricity or connect the battery, simple structure realizes opening in step and closes with the automatic escalator, avoids appearing that the antiseptic solution sprays the condition that leads to not disinfecting thoroughly inadequately or the automatic escalator closes and still spray the antiseptic solution and lead to extravagant condition and need not the controller and can realize the control to disinfection opportunity.

The piston pump 75, the check valve and the nozzle 21 are all conventional products, and are conventional products available in the market.

The shell 1 is fixedly arranged on the glass 81 of the escalator, the handrail 8 penetrates through the shell 1, the wiping piece 23 is provided with disinfectant, the handrail 8 moves relative to the wiping piece 23, the wiping piece 23 wipes the disinfectant on the handrail 8, and the handrail 8 is disinfected in real time in actual use; the nozzle 21 is arranged on the shell 1 through the nozzle bracket 2, the spray head of the nozzle 21 faces the handrail 8, the nozzle 21 sprays the disinfectant pumped by the liquid pumping mechanism from the liquid storage tank 12 onto the handrail 8, the nozzle bracket 2 is positioned at the rear of the advancing direction of the handrail 8, the nozzle 21 firstly sprays the disinfectant onto the handrail 8, the handrail 8 with the disinfectant moves towards the wiping piece 23, the wiping piece 23 absorbs the disinfectant and uniformly coats the disinfectant onto the handrail 8, the disinfectant on the wiping piece 23 can be supplemented through the nozzle 21, meanwhile, the disinfectant is firstly sprayed on the handrail 8 and then is coated on the handrail 8 by the wiping piece 23, the disinfectant is directly absorbed by the bottom surface of the wiping piece 23 contacted with the handrail 8 and can be coated on the handrail 8 at the first time, namely, the disinfection effect reduction caused by the fact that the disinfection solution is exposed in the air for a long time is avoided, meanwhile, the disinfection solution adsorbed by the wiping piece 23 can be quickly supplemented, and the disinfection effect on the handrail 8 is ensured.

In actual installation, the handrail disinfection device is installed at the tail end of the running direction of the escalator, the handrail 8 can rotate to the inner side of the escalator at the moment, the disinfectant contains alcohol, so that the disinfectant coated on the handrail 8 can volatilize when the inner side of the escalator runs, the disinfectant can completely volatilize when the handrail 8 rotates to the outer side again, and at the moment, the handrail 8 does not have viruses, so that cross infection can be avoided.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
