Description
Technical field
The utility model relates to a kind of pump, and being specifically related to one not only can gas bleeding, also can the miniature suction pump of sucking liquid.This miniature suction pump is mainly used in refrigerator and vacuumizes fresh-keeping.
Background technique
Suction pump belongs to the one of vacuum pump, and it has wide range of applications, and can be used for the various work needing gas bleeding or sucking liquid.Existing suction pump, normally realizes bleeding of pump and liquid suction function by the to-and-fro motion of piston-cylinder, but it exists volume is large, noise is high problem, and be not suitable for mini-plant, or in the place needed peace and quiet.For this reason, industry is had to have developed the suction pump of some compact, to overcome above-mentioned deficiency, but make a general survey of this type of existing small-sized suction pump, because its structural design is unreasonable, such as some small-sized suction pump is even only the scaled down version of original conventional suction pump, in Long-Time Service, therefore finds still there is following problem: one, pumping efficiency is low; Two, noise rejection effect is not good; Three, structure is not compact; Four, reliability is poor.Thus still have much room for improvement breakthrough, with the needs in response to market.
in view of this, how to improve the pumping efficiency of extraction pump, reduce its operating noise, make its structure more compact and improve the reliability of its work, just become the problem that the utility model need solve.
Summary of the invention
The utility model provides a kind of miniature suction pump, its object is to the many deficiencies solving prior art existence.
For achieving the above object, the technical solution adopted in the utility model is: a kind of miniature suction pump, comprises air pump assembly and motor; Described air pump assembly and motor are vertically arranged above and below, and the rotating shaft of described motor is upwards connected with described air pump assembly; Described air pump assembly comprises the rocker stand, flexible partition group and the valve member that arrange from bottom to top; Wherein,
Described rocker stand is made up of rocking arm and plate-like support body two-part, described rocking arm is located in the discoidal central of described plate-like support body; the other end of rocking arm is connected with by the rotating shaft of an eccentric structure and described motor, moves in horizontal plane with the plate-like support body ordering about described rocker stand along circular trace; Described plate-like support body is provided with two to eight positioning holes, and each positioning hole is uniformly distributed around the center of described plate-like support body;
The plate-like support body of the corresponding described rocker stand of described flexible partition group is arranged, and is wholely set and multiple flexible partition of the quantity such as described positioning hole and multiple catch; Lower surface and the upper surface of described flexible partition group is divided in described flexible partition and catch one outer; And each described catch interlock is arranged at the upper end outer rim of each described flexible partition, the lower end of each described flexible partition is then positioned in each positioning hole of the plate-like support body of described rocking carrier on the other side; Wherein, each described positioning hole is equal to the distance at the center of flexible partition group with the lower end of each described flexible partition to the distance at the center of plate-like support body; Wherein, between two adjacent catch, there is a gap;
The corresponding described flexible partition group of described valve member is arranged, and comprises and the multiple unidirectional suction valve of the quantity such as described flexible partition and the exhaust port being located at this valve member center; The upper end of each described unidirectional suction valve is all connected with a pump port, and this pump port is communicated with the inner space of object to be pumped, and described exhaust port is communicated with the space outerpace of object to be pumped; The lower end of each unidirectional suction valve corresponding is with it located at by the upper end seal closure of each described flexible partition, with in forming an airtight chamber between the two; On the sidewall of described exhaust port, the corresponding unidirectional suction valve closed on offers a runner; The catch of described flexible partition group stretches in described exhaust port, and the corresponding each runner of each catch is arranged, and has close and open two states to make described runner;
When described rocker stand drive via described motor and produce circumference wave time, by each positioning hole on the plate-like support body of rocker stand each flexible partition of locating by the displacement due to described plate-like support body by successively tractive and compressing; When certain flexible partition is pulled, the described catch being located at this flexible partition upper end outer rim can move in direction towards the opposite simultaneously, thus block and close the described runner corresponding with it on described exhaust port, make to produce negative pressure in the airtight chamber between this flexible partition and described unidirectional suction valve corresponding with it, and then open described unidirectional suction valve and carry out bleeding or imbibition; The gas be drawn into or the liquid be inhaled into are temporary in corresponding described airtight chamber; And when described rocker stand waves to another location, the described flexible partition be pulled will be put down and be oppressed, the described catch corresponding with it then opens the runner closed by it, makes to produce malleation in corresponding described airtight chamber, thus closes corresponding described unidirectional suction valve; Now, the gas be before drawn into or the liquid be inhaled into enter described exhaust port by because of described opening once again of runner and discharge via this exhaust port.
Related content in technique scheme is explained as follows:
1. in such scheme, each positioning hole is uniformly distributed around the center of described plate-like support body, the tractive of equivalence during can ensure when described plate-like support body moves successively to carry out waiting to each described flexible partition or contention effect, and then realize " uninterruptedly " suction again and again.
2. in such scheme, described multiple flexible partition and multiple catch one-body molded, not only increase tightness, the linkage between each flexible partition and catch corresponding with it can be made simultaneously better.
