Embodiment Construction
[0022] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.
[0023] Such as Figure 1~3 Shown is Embodiment 1 of the present invention, an air transmission controller, including a control device 11 and an execution device 22 provided with a high-voltage control switch 21, and an air pipe 1 is provided between the control device 11 and the execution device 22; The manipulation device 11 includes a first airbag 2 communicating with the trachea 1 . When in use, the air pressure generated by pressing the first air bag 2 is transmitted to the actuator 22 through the air pipe 1, and the actuator 22 uses the air pressure difference to drive the high-voltage control switch 21 of the high-voltage circuit to realize the control function of the air transmission....

The invention relates to an air drive control device and particularly relates to an air drive controller which utilizes low-pressure air drive to realize the control on a high-voltage circuit. The air drive controller comprises a control device and an executive device, wherein the executive device is used for connecting a high-voltage control switch, an air pipe is arranged between the control device and the executive device, and the control device comprises a first air bag communicated with the air pipe. When the air drive controller is used, the first air bag is pressed to generate air pressure, the air pressure is transferred to the executive device by virtue of the air pipe, and the executive device utilizes air pressure difference to drive the high-voltage control switch of the high-voltage circuit to realize the control function of air drive; as the air drive controller utilizes the air pressure difference generated by the first air bag to drive the executive device, a user is prevented from contacting the circuit, and the potential safety hazard of electric shock is eliminated completely; and as the air drive controller does not utilize any electric element, the requirements on materials are not high, and thus the production cost is reduced greatly.
Description
Technical field: [0001] The invention relates to an air transmission control device, in particular to an air transmission controller which utilizes low-pressure air transmission to control a high-voltage circuit. Background technique: [0002] There are the following types of existing electrical switch controllers. One is to use artificially set time circuit timing and mechanical travel time to control on and off. This method is relatively mechanized, inconvenient to use, inflexible, and prone to failure ; The other is to use a low-voltage circuit to control a high-voltage circuit. This control method needs to be equipped with a variety of electronic components, the equipment is complex, the production cost is high, the operation and maintenance costs are also high, and the anti-interference is low, which is not conducive to widespread use. [0003] Chinese patent authorization announcement number CN2192986Y discloses a switch controller that uses low-voltage micro-current ...
