Problems solved by technology

[0002] Ejectors use high-speed water flow or other fluids to absorb air to create vacuum conditions. However, existing ejectors can only be adjusted by changing the fluid velocity. When the flow velocity is constant, it cannot be adjusted to meet the needs. Therefore, there is an urgent need for an adjustable method of using an ejector to obtain a vacuum. This device speeds up the pumping efficiency and quickly produces a vacuum effect. At the same time, it can be adjusted to control the required vacuum degree to meet the use requirements. The operation is simple. easy to use

Abstract

The invention discloses a method for obtaining vacuum through an ejector. A device used in the method comprises a first device body, a control device arranged in the first device body and an ejectingdevice arranged in the first device body; the control device comprises a first transmission cavity formed in the first device body, a first motor is fixedly arranged in the inner wall of the rear sideof the first transmission cavity, the front end of the first motor is in power fit connection with an irregular gear, the right side of the irregular gear is engaged with a first straight gear, the right side of the first straight gear is engaged with a second straight gear, and the front end of the second straight gear is fixedly connected with a first rotating shaft. The air exhaust efficiencycan be improved, the vacuum effect can be rapidly generated, meanwhile, the needed vacuum degree can be controlled through adjustment, use needs are met, operation is easy, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of vacuum suction, in particular to a method for obtaining vacuum by using an ejector. Background technique [0002] Ejectors use high-speed water flow or other fluids to absorb air to create a vacuum condition. However, the existing ejectors can only be adjusted by changing the velocity of the fluid. When the flow rate is constant, it cannot be adjusted to meet the needs. Therefore, there is an urgent need for an adjustable method of using the ejector to obtain vacuum. This device speeds up the pumping efficiency, so that the vacuum effect can be generated quickly, and at the same time, the required vacuum degree can be controlled by adjustment, so as to meet the use requirements, and the operation is simple. Easy to use. Contents of the invention [0003] The object of the present invention is to provide a method for obtaining vacuum by using an ejector, which is used to overcome the above-mentioned def...
