Description

Electric sucking disc and control method thereof Technical Field The application relates to the field of adsorption devices, in particular to an electric sucking disc and a control method thereof. Background The mobile phone support is used as a common auxiliary device, and the fixing mode of the mobile phone support is important for the use experience and the safety of the device. In the prior art, a number of brackets have employed suction pads to secure them to a support surface, such as an automobile instrument desk or glass. The traditional sucking disc relies on manual pressure to discharge air in order to produce the negative pressure, but because reasons such as adsorption surface roughness or material ageing, outside air can slowly infiltrate inside the sucking disc, leads to the negative pressure to weaken gradually, finally causes the unexpected whereabouts of sucking disc, and electric sucking disc can solve above-mentioned problem. However, in order to maintain the adsorption capacity, the existing electric sucking disc is usually continuously pumped after a power supply is started, and as the equipment cannot sense the actual vacuum degree change in the adsorption cavity, no matter whether the current negative pressure meets the adsorption requirement or not, the motor is always in a full-load running state, so that the electric quantity of a battery is not consumed, the endurance time of the equipment is shortened, the motor continuously runs for a long time to generate noise, the mechanical abrasion of the motor and a pump body is accelerated, and the electric sucking disc is also provided, the internal vacuum degree is monitored by adopting a pressure sensor, the pressure sensor is always in a working state, the electric quantity of the battery is consumed, and the endurance time of the equipment is shortened. Disclosure of Invention In order to solve the technical problems in the prior art, the application provides an electric sucking disc. The application provides an electric sucking disc which adopts the following technical scheme: An electric chuck, comprising: The sucker body comprises a shell and an adsorption pad fixedly arranged on the shell, and an adsorption area is formed on one side, away from the shell, of the adsorption pad; The suction mechanism is accommodated in the shell and comprises a negative pressure driving assembly, and the negative pressure driving assembly is used for extracting the gas in the adsorption zone; the pressure sensing mechanism has a sensing end communicated with the adsorption area and comprises a pressure response piece, a switch pushing block and a pressure sensor, wherein one side of the pressure response piece, which is away from the adsorption area, is communicated with the outside atmosphere, and can be displaced in response to the change of the air pressure of the adsorption area, the switch pushing block is driven by the pressure response piece, and The control mechanism is contained in the shell, and comprises a control unit electrically connected with the negative pressure driving assembly to control the start and stop of the negative pressure driving assembly, a main switch used for controlling the start and stop of the control unit and a sub-switch matched with the switch pushing block in an abutting mode, wherein the control unit is electrically connected with the separation part and receives signals of the sub-switch to start and stop the negative pressure driving assembly. By adopting the technical scheme, when the negative pressure driving assembly works to reduce the air pressure of the adsorption area, the pressure response piece communicated with the adsorption area is displaced under the action of pressure difference, and then the pressure response piece drives the switch pushing block to act with the separation switch, so that the state of the separation switch is changed, and the control unit responds to the state change of the separation switch to further control the negative pressure driving assembly to stop working so as to maintain the pressure. When the air pressure of the adsorption area rises due to air leakage, the pressure response piece is pressed to change to reset, and the switch pushing block is driven again to enable the separation switch to recover to the initial state, and the control unit responds to the change to restart the negative pressure driving assembly to supplement air. Preferably, the shell comprises a mounting base plate for mounting the adsorption pad, a rotating ring and a cover body fixed with the mounting base plate, wherein the rotating ring is positioned between the cover body and the mounting base plate and is respectively in rotating connection with the mounting base plate and the cover body, and a driving shifting block matched with the main switch is formed on the inner wall surface of the rotating ring. Through adopting above-mentioned technical scheme, when the swivel becket rotates for the
