Abstract

The invention discloses a spraying air supplementing pump capable of being adjusted and controlled, and relates to the field of spraying air supplementing pumps. The following scheme is currently provided in order to solve the problems that the internal pressure of an existing air supplementing pump cannot be adjusted, so that objects to be subjected to air supplementing are easily damaged. The spraying air supplementing pump comprises a body, an inlet, a nozzle and an air supplementing pump body. The spraying air supplementing pump is characterized in that a baffle is arranged in the body, passageways are formed in the front side edge and the rear side edge of the baffle, a motor is arranged on the left side of the body, the output end of the motor is fixedly connected with a screw, the surface of the screw is sleeved with a first push plate through threads, the front side edge and the rear side edge of the first push plate are fixedly connected with connecting plates, the ends, awayfrom the first push plate, of the connecting plates are fixedly connected with a second push plate, the right side face of the baffle is fixedly connected with a connecting rod, groove bodies are formed in the front inner wall and the rear inner wall of the body, and rotary plates are movably connected into the groove bodies. The device has the beneficial effects that the spraying air supplementing pump is conveniently adjusted, the air pressure during internal inflation can be changed, and the to-be-inflated objects are well protected.

Description

technical field [0001] The invention relates to the field of jet air supplement pumps, in particular to an adjustable jet air supplement pump. Background technique [0002] The jet air pump is a vacuum generating device that is controlled by pneumatic or electric means to realize the first contraction and then expansion of the gas inside the pump body. Normally, the adjustable injection pump is divided into an inlet section, a constriction section, a negative pressure section and a diffusion section. The principle of the adjustable jet air supply pump is that the steam enters from the inlet section of both ends of the water vapor and the pumped gas, and is ejected through the shrinking nozzle, the flow speed is accelerated, and a negative pressure area is formed on the back side of the nozzle, and the two media are fully mixed, so that The energy is fully exchanged, and the speed is gradually consistent. After diffusion and amplification, the kinetic energy is converted int...
