Problems solved by technology

[0002] During the use of equipment such as oxygen generators, pressure or vacuum is usually alternately input into the working chamber. At present, it is usually necessary to equip a vacuum pump and a pressure pump to cooperate to output vacuum and pressure at the same time. , the two pumps work independently, occupy a lot of space, have a large volume, and the noise of each working is also very loud, which is not conducive to the use of small equipment such as oxygen generators

Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] see Figure 1 to Figure 7 As shown, a pressure vacuum control pump, the control pump includes a pump body 1 and a vacuum container 2 arranged on the pump body 1, an eccentric wheel 4 rotatably arranged on the pump body 1, and a device for driving the eccentric wheel 4 to rotate The motor 3, and the vacuum piston rod 5 and the pressure piston rod 6 which are driven by the eccentric wheel 4 to perform reciprocating linear motion.

[0026] The vacuum container 2 has a vacuum chamber 21 and a pressure chamber 22 that are isolated from each other and are not connected to each other. The pump body 1 is provided with a vacuum piston chamber 7 and a pressure piston chamber 8. The vacuum piston chamber 7 and the pressure piston chamber 8 are separately arranged on the eccentric wheel 4. The vacuum piston rod 5 is set i...

Abstract

The invention discloses a pressure vacuum control pump. The pressure vacuum control pump comprises a pump body, an eccentric wheel, a motor, a vacuum piston rod, a pressure piston rod and a vacuum container, wherein the eccentric wheel is rotationally arranged on the pump body, the motor is used for driving the eccentric wheel to rotate, the vacuum piston rod and the pressure piston rod are drivenby the eccentric wheel to do reciprocating rectilinear motion, the vacuum container is arranged on the pump body, the vacuum container is provided with a vacuum cavity and a pressure cavity which areisolated from each other, the pump body is provided with a vacuum piston cavity and a pressure piston cavity, the vacuum piston cavity and the pressure piston cavity are arranged on the two differentsides of the eccentric wheel correspondingly, and the vacuum piston rod can be axially arranged in the vacuum piston cavity in a sliding mode. The pressure vacuum pump integrates two functions of a vacuum pump and a pressure pump, and can simultaneously output vacuum and pressure, the pressure vacuum control pump is large in output flow, small in noise, small and compact in structure and capableof cooperating with a small medical instrument such as an oxygenerator for use.

Description

technical field [0001] The invention relates to a pressure vacuum control pump. Background technique [0002] During the use of equipment such as oxygen generators, pressure or vacuum is usually alternately input into the working chamber. At present, it is usually necessary to equip a vacuum pump and a pressure pump to cooperate to output vacuum and pressure at the same time. , The two pumps work independently, take up space, have a large volume, and the noise of each working is also very loud, which is not conducive to the use of small equipment such as oxygen generators. Contents of the invention [0003] The object of the present invention is to provide a pressure-vacuum control pump capable of simultaneously outputting vacuum and pressure. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a pressure vacuum control pump, the control pump includes a pump body, an eccentric wheel rotatably arranged on the pump ...
