Embodiment approach

[0034] The screw rod 71 of the present invention is a single-rotation reciprocating screw rod. In the second embodiment of the present invention, a unidirectional motor is used to cooperate with a single-rotation reciprocating screw rod to form a driving mechanism, wherein the structure of the single-rotation reciprocating screw rod is not provided with a double helix on the rod body, and a connecting double screw is provided at the end of the rod body. The connecting part of the spiral, when the blade rotates from one of the spiral tracks to the end of the rod body, the blade passes through the connecting part and enters the other spiral track to move in reverse, so that the blade moves back and forth.

[0035] In the present invention, a guide cylinder 9 is provided in the pump body 1, and the blade 3 is an iron blade. The blade 3 is sleeved on the guide cylinder 9 and is dynamically sealed with the outer wall of the guide cylinder 9. The wire The rod 71 is arranged in the g...

Abstract

The invention discloses a microfluid pump. The microfluid pump comprises a pump body, wherein a cavity is formed in the pump body. The microfluid pump is characterized in that a blade is movably arranged in the cavity, a sealing space is formed between the end surface of the blade and at least one end of the pump body, a fluid inlet and a fluid outlet which communicate with the sealing space are respectively formed in the pump body on the same side as the blade, the fluid inlet is connected with a first check valve, the fluid outlet is connected with a second check valve, and a driving mechanism which is capable of driving the blade to translate back and forth in the cavity is arranged on the pump body. The microfluid pump has the advantages of simple structure, less noise and high fluid pumping efficiency.

Description

technical field [0001] The invention relates to the field of fluid pumps, in particular to a microfluid pump. Background technique [0002] Fluid pumps are machines that transport or pressurize liquids. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, suspoemulsions and liquid metals, etc., and can also transport liquid and gas mixtures. and liquids containing suspended solids. Due to design defects, existing microfluid pumps generally have problems such as complex structure, low pump fluid efficiency, and high noise. [0003] Therefore, the existing microfluidic pump needs to be further improved. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies in the prior art and provide a micro fluid pump with simple structure, low noise and high pump fluid effi...
