The elevator button sterilizing device based on the ratchet mechanism and ultraviolet light further comprises a photoelectric sensor 7, and the photoelectric sensor 7, the ultraviolet light sterilizing device 5, the driving device 3 and the transmission device 4 are electrically connected.

In this embodiment, when the set sterilization condition is satisfied, the ultraviolet lamp beads are started to perform ultraviolet sterilization, and when the set condition is not satisfied, the ultraviolet lamp beads are turned off.

The ratchet mechanism 1 mainly comprises a knob 13, a pawl 15 and a one-way bearing 12. The passenger rotates the knob 13, and the knob 13 drives the pawl 15 to regularly swing so as to trigger the original elevator button.

Further, the pawl 15 is mounted on the slider 24 so as to be slidable on the slide rail 23 with the slider 24.

Meanwhile, as the sliding block 24 is a ironwork, the sliding block 24 can be attracted when the electromagnet 22 works, the sliding block 24 and the pawl 15 can approach the electromagnet 22 together, and the sliding block 24 and the pawl 15 can reset under the action of the spring 26 when the electromagnet 22 does not work.

The sliding block 24 and the pawl 15 may interfere with the knob 13 in the resetting process and cannot be normally reset, but when someone uses the elevator, the sliding block 24 and the pawl 15 can be automatically and normally reset under the elastic force of the spring 26 in the process of selecting the knob 13.

Further, the rotating shaft of the motor 31 is connected with the main shaft 11 through the coupler 32, and when the motor 31 is started to drive the main shaft 11 to rotate, the knob 13 is driven to rotate for sterilization. In particular, since the knob 13 is connected to the main shaft 11 by the one-way bearing 12, the passenger can rotate the knob 13 and the motor 31 can also rotate the knob 13 by rotating the main shaft 11.

Further, a supporting rod 25 is fixed between the electromagnet 22 and the sliding block 24, so that the spring 26 can be effectively limited, and the sliding block 24 can be prevented from moving on the sliding rail 23 due to the inclination of the sliding block 24 caused by a gap between the sliding block 24 and the sliding rail 23.

Preferably, a synchronizing wheel 41 and a synchronizing belt 42 are used as the transmission 4, and a tensioner is provided to prevent the belt from slipping so that the rotational speeds of the main shafts 11 are uniform.

Further, a control system is arranged in cooperation with the electricity, and the control system can automatically control the motor 31, the electromagnet 22 and the ultraviolet lamp beads to work.

The specific use cases are as follows:

the use of the elevator button disinfection device can be divided into two time periods, namely a normal use time period and a uniform disinfection time period. Both of these periods are set by the control system.

After the device is started, the device is in a normal use period, the ultraviolet lamp set is started at this time, and the knob 13 is not used by passengers (as shown in fig. 5). When the passenger needs to start the elevator, only need rotate knob 13, knob 13 can drive pawl 15 and swing to press the original button of elevator (as fig. 6), in this process, the ultraviolet banks is in the state of opening all the time, is disinfecting for knob 13 is in the part of shell 6 always, and the passenger after rotatory knob 13, the knob 13 part that the passenger contacted can be rotated to the inside ultraviolet light disinfection of shell 6, and will be rotated out with the part of disinfecting for next passenger to use.

Generally, the normal use stage can meet the requirements of sterilization and disinfection, but in order to prevent passengers from touching the knob 13 in the use process of the elevator, the knob 13 is not rotated, so that microorganisms such as bacteria carried by the hands of passengers remain on the knob 13, and passengers at lower positions can be inadvertently touched with the microorganisms such as the residual bacteria when using the knob 13. The elevator button disinfection device is also provided with a unified disinfection time period.

When the specified time is reached, the device is automatically switched from the normal use time period to the uniform disinfection time period, in the uniform disinfection time period, the photoelectric sensor 7 is started, the device judges whether passengers exist in the elevator according to the data transmitted by the photoelectric sensor 7, and if no passengers exist, the device is automatically unified to be used for disinfecting the knob 13. After the absence of a person is determined, the electromagnet 22 will be started, the original ratchet mechanism 1 (fig. 7) will attract the slider 24 and the pawl 15 to the magnet side, so that the knob 13 and the pawl 15 cannot form the ratchet mechanism 1 (fig. 8), and then the motor 31 will be started to drive the spindle 11 and the knob 13 to rotate, so that the knob 13 originally located in the housing 6 is partially rotated into the housing 6, and the ultraviolet light in the interior is used for sterilizing the housing 6. After the preset uniform sterilization time is finished, the motor 31 is turned off, the spindle 11 and the knob 13 stop rotating, the electromagnet 22 is turned off, and the slider 24 and the pawl 15 are reset under the action of the spring 26. During the resetting, the pawl 15 and the knob 13 may interfere with each other (see fig. 9). This is a normal phenomenon, and when a passenger rotates the knob 13, the pawl 15 is normally reset by the elastic force of the spring 26 (see fig. 10). The reason for this is that the slider 24 (shown in fig. 11) restricts the rotation angle of the pawl 15, and even if the pawl 15 interferes with the knob 13, only the knob 13 needs to be rotated, the teeth of the pawl 15 can still be parallel to the tooth grooves in the knob 13. Thus, under the action of the elastic force of the spring 26, the pawl 15 can be normally reset only by rotating the knob 13. After the pawl 15 is reset, the elevator button disinfection device will again return to the normal use phase. If the photoelectric sensor 7 detects that passengers are still in the elevator, neither the electromagnet 22 nor the motor 31 can activate the elevator button, and the sterilizing device is still in the normal use period. If the photoelectric sensor 7 detects that a person enters the elevator when the motor 31 is in operation, the motor 31 will stop immediately, and the electromagnet 22 will also stop after the motor 31 stops, and the unified disinfection period will switch back to the normal use period quickly.

Compared with the prior art, the ultraviolet disinfection device has the beneficial effects that the structure is simple, the operation is convenient, the button is replaced by the knob 13, ultraviolet light disinfects the knob 13 in real time, and passengers are contacted with the disinfected knob 13 when using the ultraviolet disinfection device every time, so that the passengers can be effectively prevented from being contacted with microorganisms such as bacteria and the like, and the propagation of the microorganisms such as bacteria and the like can be effectively prevented.

The above disclosure is only a preferred embodiment of the present utility model, and it should be understood that the scope of the utility model is not limited thereto, and those skilled in the art will appreciate that all or part of the procedures described above can be performed according to the equivalent changes of the claims, and still fall within the scope of the present utility model.
