Description

A contactless safety elevator for novel coronavirus epidemic prevention

Technical Field

The invention relates to a control system of an elevator, in particular to a contact-free safety elevator for novel coronavirus epidemic prevention.

Background

The new coronavirus epidemic is still severe and it is most likely that the new coronavirus is transmitted by close contact with the infected person. In addition indirect contact also leads to viral transmission, expert laboratory tests have shown that new coronaviruses can survive for hours to days on plastic and stainless steel surfaces, and in addition viruses similar to those responsible for major outbreaks of epidemic disease have been found to be most suitable for survival on smooth hard surfaces. Spray disinfection is an effective method, has better disinfection effect compared with ultraviolet rays, and is easier to implement compared with high-temperature disinfection.

When people take the elevator, the people need to touch the keys of the elevator, the keys can become carriers for spreading viruses, individual users can prepare paper towels or disinfectant wet tissues, and some elevators are provided with paper drawers, so that the direct contact between fingers and the keys is avoided, but the used paper towels or wet tissues are not provided with reasonable recovery devices, the environment of the elevator can be influenced, and the keys can be pressed by the user with personal articles such as keys instead of the fingers. Most users still directly touch the keys with fingers, and the problem of virus propagation through indirect contact is not solved fundamentally.

Disclosure of Invention

The invention aims to provide a contact-free safety elevator for preventing novel coronavirus epidemic, which is characterized in that buttons of a control panel are automatically sterilized in the normal use process, so that the virus is prevented from being spread through the buttons.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

a contact-free safety elevator for preventing coronavirus from epidemic is composed of a cage, a control panel in the cage and/or at the door opening of cage, and a button on the control panel for automatically disinfecting.

The first scheme is that a layer of isolating membrane which can rotate and perform cyclic disinfection in the rotating process is arranged on the surface of a control panel shell, and the isolating membrane covers the keys.

The button vertically sets up side by side, and right side button is listed as the surface and is set up first barrier film, and left side button is listed as the surface and is provided with the second barrier film, the barrier film is closed loop cover tube-shape, is provided with first beam barrel and third beam barrel in first barrier film, and the beam barrel both sides all are provided with the bearing, and first beam barrel and third beam barrel prop first barrier film into the platykurtic, and the button is listed as and is put between two-layer barrier film in the front and back, are provided with first gear at the tip of first beam barrel, and the setting and the right side symmetry of left side button row, and the second barrier film props up through second beam barrel and fourth beam barrel, is provided with the second gear on the second beam barrel, second gear and first gear engagement to be connected with driving motor at first beam barrel, be provided with flexible disinfection strip in the surface side of first barrier film and second barrier film or rear.

The user is when the button of elevator is pressed to needs, cover the barrier film on button surface and can avoid finger and button direct contact, but do not influence user's normal operating, driving motor drives first gear and first arbor roller and rotates, first gear and second gear meshing, give the second arbor roller with power transmission, first arbor roller and second arbor roller are for providing power for first barrier film and second barrier film respectively, make barrier film circulation reciprocal rotation, the contact point of user and barrier film is disinfected through the flexible disinfection strip that has the antiseptic solution at the rotation in-process, later rotate the button surface again and use, thereby the virus has been avoided propagating through indirect contact.

Preferably, the flexible disinfection strip is connected with the disinfectant storage, and the disinfectant is automatically supplied to the flexible disinfection strip by utilizing the capillary phenomenon.

The second proposal is that the key is an independent key unit module capable of automatically sterilizing, the key unit module comprises a spherical button, a shaft roller, a one-way bearing, a gear, a guide rail, a spring, a rack, a switch, a module base, a sterilizing liquid nozzle and a liquid inlet, a shaft roller penetrating through the center of the sphere is arranged on the spherical button, two ends of the shaft roller penetrate through a guide rail with a guide groove, the guide rail is fixedly arranged on the module base, a spring is arranged in a guide groove of the guide rail, a gear is arranged at the end part of the shaft roller, the gear is connected with the shaft roller through a one-way bearing, the gear is meshed with a rack fixed on a module base, a disinfectant nozzle and a liquid inlet are arranged on the module base, the disinfectant nozzle is right opposite to the spherical button, the liquid inlet is connected to a disinfectant storage box, the module base is also provided with a switch which is used as an electrical switch of the key unit module and triggers the spray disinfection action through electrical control association.

The working principle is as follows, when a user needs to press an elevator key, the finger of the user and the spherical button move towards the direction close to the module base after applying force, the gear and the rack are matched in the moving process to enable the gear to rotate, but because the one-way bearing is arranged between the gear and the shaft roller, the one-way bearing is in a flexible rotating state and serves as a common bearing, when the spherical button moves inwards under the action of external force, the acting force of the rotation of the gear can not act on the spherical button, namely the spherical button can not rotate, when the spherical button is pressed to the bottom, the switch is triggered to send a corresponding command to the elevator control system, and the disinfection liquid nozzle is triggered to spray and disinfect the back of the spherical button through the electric system, after the user presses the button, the finger is released, the spherical button can rebound under the action of the spring, the in-process kick-backs, the gear rolls on the rack, the one-way bearing that sets up this moment between gear and beam barrel is the lock dead state, under the one-way bearing lock dead state, the torsion of gear can transmit for spherical button through one-way bearing and beam barrel, make spherical button at the in-process rotation of kick-backing, the rotation angle is about 180, after spherical button resets, face after the spraying disinfection is just to the user, circulate in proper order, the rotation process need not set up the power supply alone, can reach the sterile purpose of not intermittent type.

Preferably, the key unit module further comprises a slider, and the slider is arranged between the spring and the shaft roller. The slider is used for guiding the spherical button in the pressing process, so that the spherical button is prevented from being clamped due to uneven stress left and right in the pressing process.

The invention has the beneficial effects that:

according to the contact-free safety elevator, the control panel of the elevator is provided with the keys capable of being automatically sterilized, the keys can be automatically sterilized after a user presses the elevator keys, the sterilization process and the operation and control process are synchronously performed, normal use of the elevator is not affected, the mode conforms to the operation habit of the user, the popularization and the implementation are easy, and the potential safety hazard of spreading new crown viruses caused by operation and control of the keys when the user takes the elevator can be fundamentally avoided.
