Description
Technical field
The present invention relates to fluid pump technical fields, and in particular to a kind of minisize fluid pump.
Background technique
What minisize fluid pump referred to is exactly micro air pump or liquid pump, refers to the air exhaust nozzle for having one-in-and-one-out, exhaust nozzle each one
It is a, inside by mechanical device make to pump inside diaphragm do reciprocating, and entrance can persistently be formed vacuum or
Negative pressure forms micro-positive pressure at exhaust nozzle；Working media is mainly gas or fluid, and a kind of instrument of compact is transported extensively
For coffee machine, beer brewing machine, blood pressure machine, water purifier etc..
Existing minisize fluid pump generally adds swing rod using eccentric wheel, and roll structure becomes diaphragm in vertical direction
Shape so that diaphragm generates volume variation, and then changes the pressure inside diaphragm, realize gas or fluid in diaphragm into
Out.It is had the disadvantage in that using the above structure in minisize fluid pump work, ball and swing rod rub for a long time, easily lead to pendulum
Bar or ball are seriously worn, and diaphragm is deformed in vertical direction, swing rod deformation are easily led to, therefore, using inclined
Heart wheel adds swing rod, and roll structure, the diaphragm deformation degree for being easy to cause minisize fluid to pump is different, and then is difficult to ensure minisize fluid
The consistency of pump discharge；Meanwhile eccentric wheel adds swing rod, roll structure, the space occupied is larger at work, so as to cause miniature
Fluid pump volume becomes larger, therefore the use for influencing minisize fluid pump has much room for improvement.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of minisize fluids to pump, can be more
