Detailed Description

The following describes the embodiments of the present invention in detail. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the present invention, the use of the terms of orientation such as "upper and lower" in the case where no description is made to the contrary generally means the orientation in the assembled and used state. "inner and outer" refer to the inner and outer contours of the respective component itself.

The utility model discloses in provide one kind and realize opening or closing of corresponding equipment under the condition of contactless switch, avoid because the personnel contact more and bring if the insanitation, spread infectious disease scheduling problem easily.

In order to achieve the above object, the present invention provides a non-contact type switch triggering device, as shown in fig. 1, comprising:

a button 1 for triggering a carrier of a device;

the sensor 2 is used for judging whether the request end is in the threshold value of the area range set by the button 1 and the request end;

the relay 3 is electrically connected with the sensor 2 and is used for converting the signal generated by the sensor 2 into current;

and the driving mechanism is electrically connected with the relay 3 and is used for driving the button 1 to trigger equipment.

Through the technical scheme, when the request end is located in the area range which can be sensed by the sensor 2, the sensor 2 is triggered and transmits a sensing signal to the relay 3, the relay 3 converts the sensing signal into current, and the driving mechanism drives the button triggering device after receiving the current signal. In this manner, the associated device can be triggered (turned on or off) without the need to directly press a button. Therefore, the problems of insanitation and easy virus transmission caused by a contact switch are solved.

The non-contact switch trigger device also comprises a shell 6 with a hollow interior, and the button 1 is partially inserted into the shell 6 and is connected with the side wall of the shell 6 in a sliding way; the sensor 2 is arranged on the shell 6 on the same side as the button 1; the relay 3 is disposed within the housing 6.

In the above, the driving mechanism includes a return spring 4 and an electromagnet 5, and the relay 3 is electrically connected to the electromagnet 5; one end of the reset spring 4 is connected with the button 1, the other end of the reset spring is connected with the electromagnet 5, the reset spring 4 has a tendency of pushing the button 1 to the outside of the shell 6, and the electromagnet 5 has a tendency of pulling the button 1 to the inside of the shell 6 after being electrified.

The slidable movement of the button 1 and the housing 6 can be achieved by: as shown in fig. 3, a slider 11 is disposed on a side wall of the button 1, and a sliding groove 12 adapted to the side wall of the housing 6 is disposed thereon. The slider 11 and the sliding groove 12 not only enable the sliding connection between the button 1 and the housing 6, but also prevent the button 1 from being detached from the housing 6. Preferably, the button 1 and the electromagnet 5 are located on the same straight line.

In order to make the push button 1 attracted by the electromagnet 3 energized, an iron piece may be provided at the right end of the push button 1 as shown in fig. 1. It is of course also possible to provide the entire push button 1 made of a metal material, such as iron, copper, etc.
