Abstract

A micro vacuum pump is characterized in that an output shaft of a DC motor is connected with an eccentric wheel; a swing bar bracket is arranged between the eccentric wheel and a stator; a swing bar sphere at one end of the swing bar is connected with the eccentric wheel; a swing bar sphere at the other end of the swing bar is connected with the stator; the DC motor moves to drive the eccentric wheel to rotate, is connected with the eccentric wheel through the swing bar in the swing bar bracket, and swings angularly taking the swing bar bracket as a pivot to drive the swing bar to move axially and generate air-inhaling or air-exhausting motion among minimal drum eccentric torque, radial swinging force and axial force and maximal eccentric torque, radial swinging force and axial force; an air suction pipe and an exhaust pipe are arranged at the end of a front end cover; two umbrella-shaped air valves are arranged in an air exchanging base, a first air suction state of the umbrella-shaped air valves is communicated with the air suction pipe, and second exhaust state is communicated with the exhaust pipe; and when the first air suction state is started, the second exhaust state is stopped. The utility model is suitable to use together with vacuum preservation boxes, medical devices, household appliances, and the like.

Description

Minipump

Technical field

The utility model relates to a kind of minipump, is applicable to vacuum crisper, hygiene medical treatment equipment, household appliances, electronic instrument supporting.

Background technique

Minipump has been widely used in household electrical appliances or Medical Instruments such as drinking machine at present, and minipump is only to possess a kind of function usually, can not possess simultaneously and not only bleed but also inflate this two kinds of functions.For example the gas in the container is extracted out, making the gas in the container is negative pressure, makes the food that stores in the container play certain preservation.And the vacuum pump that has is made as the function of inflation, and this all is according to the design of the draft scheme of MANUFACTURER.Model utility title " minipump " as disclosing in the Chinese patent literature discloses the vacuum pump structure; Notification number CN1987105A and for example, denomination of invention " minipump " discloses some structures of this air pump.The characteristics of these two kinds of structures are each has something to recommend him, and to their pluses and minuses, the application does not comment in addition.

Summary of the invention

The utility model purpose is a kind of minipump that provides to related domain, makes it be matched in vacuum crisper, hygiene medical treatment equipment, household appliances with preferable performance, electronic instrument, it is better to reach usability, compact structure, it is comparatively convenient to assemble, and cost is lower, be easy to produce in batches.The purpose of this utility model is achieved through the following technical solutions.

A kind of minipump, this air pump comprise front cover, ventilation seat, umbellate form air valve, stator, enraged fixed base, tympanites, rear end cover, direct current generator, and direct current generator is connected with rear end cover, and its key points in design is:

Be connected ventilation seat and enraged fixed base between rear end cover and the front cover, the output shaft of direct current generator connects eccentric wheel, the fork support is set between eccentric wheel and the stator, fork one end fork sphere in the fork support eccentric wheel that joins, the other end fork sphere stator that joins, the direct current generator running drives eccentric wheel and rotates, connect eccentric wheel by the fork in the fork support, with the fork support is fulcrum, do the angle swing and be motoricity, drive fork and do axial motion, make the eccentric minimum force distance of tympanites, radially wobble power, axial force and eccentric maximum, force distance, radially wobble power, produce air-breathing or two kinds of functional operations of exhaust between the axial force.In the end of front cover sucking pipe and outlet pipe are set, in the ventilation seat, two umbellate form air valves are set, one umbellate form air valve suction condition communicates with sucking pipe, its two umbellate forms air valve exhaust condition communicates with outlet pipe, and the umbellate form air valve is air-breathing or exhaust is not carried out simultaneously, when one when air-breathing, it two is closed; When one was closed, it is exhaust second.

Described tympanites or be made as single umbellate form air valve, umbellate form air valve and the corresponding setting of tympanites.

Described tympanites or be at least two umbellate form air valves, umbellate form air valve and the corresponding setting of tympanites.

Minipump is dual-purpose air pump, not only bleed but also inflatable, and similar air pump only possesses a kind of function wherein, can not possess two kinds of functions simultaneously.Described minipump also is provided with different specifications, and the ting model negative pressure of vacuum in the specification reaches-60KPa, and this degree of vacuum reaches capacity; Supply gas pressure (being malleation) reaches 140～150KPa.

The utility model compact structure, it is comparatively convenient to assemble, cost is lower, be easy to produce in batches, not only is used for vacuum-packed series product, and it is supporting also to be widely used in other like product, it is little to have noise, little power consumption, volume is little, and pressure is higher, the performance that life-span is long is to design comparatively desirable a kind of minipump.

Description of drawings

Fig. 1 is a structural representation of the present utility model, and this figure is made as two umbellate form air valves.

Fig. 2 is the structural representation that is made as a umbellate form air valve.

Embodiment

In conjunction with Fig. 1, be example with minipump coupling crisper.The output shaft of direct current generator 13 connects eccentric wheel 12, fork support 9 is set between eccentric wheel and the stator, fork 10 1 end fork spheres in the fork support eccentric wheel that joins, the other end fork sphere stator that joins, the direct current generator running drives eccentric wheel and rotates, connect eccentric wheel by the fork in the fork support, with the fork support is fulcrum, do the angle swing, drive fork and do axial motion, the eccentric power of tympanites is transferred to radially wobble power, responsive to axial force is done when air-breathing at tympanites 8, and gas sucks from sucking pipe 101 gas in the crisper is discharged from outlet pipe 102.In ventilation seat 2 two umbellate form air valves 3 are set, one umbellate form air valve suction condition communicates with sucking pipe, and air-breathing being also referred to as bled, and the barotropic gas in the crisper is just inhaled empty, is in vacuum state.Its two umbellate forms air valve exhaust condition communicates with outlet pipe, and the gas in the crisper just is in barotropic state.
