Abstract
The utility model is a dual purpose electric vacuum pump for inflation and inspiration, which comprises a pump shell body, a driving device and an air sac, the air inlet and outlet of the pump shell body are provided respectively with a one-way check valve, the air sac is a flat elastic membrane, with its edge fixed on the shell body, the central part of the elastic membrane is provided with a traction end convexes outward, which is connected with the output end of the driving device. The utility model adopts the membrane air sac instead of the existing bowl typed structure, the membrane is free from being bended in utilization so that the service life is expanded and the noise is reduced, at the same time a high vacuum degree is achieved.
Description
Technical field
The utility model relates to a kind of air pump, is meant specifically a kind ofly to can be used for inflating and air-breathing dual-purpose electric vacuum pump.
Background technique
Known vacuum pump structure by pump case, can produce the drive unit of straight reciprocating motion and be bowl-shape air bag and form, by the drive unit extruding gasbag reach the inflation and air-breathing purpose.Drive unit can adopt motor as power, by an eccentric wheel circular movement of motor output end is converted into straight reciprocating motion, also can adopt magnetic coil to produce alternating magnetic field, drive is provided with the rocking arm of permanent magnet and does straight reciprocating motion, and disclosing utility model patent " ozonizer air bag type air pump " as Chinese patent ZL99251012 is exactly to adopt this drive unit.Because air bag adopts bowl formula structure, need produce bending during air bag work, the airbag wall cracky, the degree of vacuum that not only provides is little, and the noise that produces is also bigger.
The model utility content
The utility model provide a kind of more durable, high vacuum pressure, dual-purpose electric vacuum pump that noise is little can be provided.
The utility model adopts following technological scheme:
A kind of dual-purpose electric vacuum pump, comprise pump case, can produce the drive unit of straight reciprocating motion and be connected the air bag of this drive unit output terminal, pump case is provided with suction port and air outlet, described suction port and air outlet are provided with the opposite one way stop peturn valve of direction, air bag and one way stop peturn valve surround the air cavity of a sealing, described air bag is a flat flexible sheet, on this flexible sheet edge mounted pump housing, its middle part is provided with the traction end that outwards protrudes out, and this traction end is connected the output terminal of drive unit.
Aforementioned flexible sheet preferably adopts elastomer diaphragm, and its profile is generally rounded, also can be square or other shapes.
Drive unit can adopt aforesaid dual mode or other technique known, preferably adopt the mode of motor as power, can make vacuum pump smaller and more exquisite, its concrete structure is: comprise motor, be provided with an eccentric opening eccentric wheel, with the close-fitting bearing of eccentric wheel and be drive wheel cylindraceous, described motor is positioned at the pump case outside, and its output shaft is fixed in the eccentric opening; Described bearing is positioned at the drive wheel inboard, and the traction end of described flexible sheet is fixed on the drive wheel and the axle center of its line stretcher by drive wheel.This structure can guarantee that the pulling motion of drive wheel output perpendicular to diaphragm, can reduce friction, improves the degree of vacuum that produces, and prolongs the working life of diaphragm.
A kind of preferable pump case structure fixedly is made of from top to bottom successively top cover, valve seat, end cap and base, described suction port and air outlet are located on the top cover, described two one way stop peturn valves are fixed on the valve seat, described flexible sheet is located between valve seat and the end cap, and described eccentric wheel, bearing and drive wheel are located in the internal cavities of base.
Described flexible sheet traction end can be fixed on the drive wheel by screw thread, is convenient to install, dismantles and changes flexible sheet.
One or two one way stop peturn valves can be respectively established as required on described suction port and the air outlet, also a plurality of one way stop peturn valves can be established.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the utility model adopts flat flexible sheet to replace the air bag of existing bowl formula structure, flexible sheet can not produce bending during work, improve working life, reduced noise, can produce higher degree of vacuum simultaneously.

Embodiment
The ginseng accompanying drawing describes embodiment of the present utility model in detail below.
This dual-purpose electric vacuum pump adopts motor 8 as power resources, and the output terminal of motor 8 is fixed in the eccentric opening 75 on the eccentric wheel 74.Pump case is made up of top cover 1, valve seat 2, end cap 3 and base 4, is fixed together by 4 screws 13, and suction port 11 and air outlet 12 are located on the top cover 1, is respectively equipped with one way stop peturn valve 51 and 52 on suction port 11 and the air outlet 12.Elastomer diaphragm 6 is located between valve seat 2 and the end cap 3, and its middle part is provided with threaded stem 61.Drive wheel 72 is provided with the tapped hole that matches with threaded stem 61, and threaded stem 61 is fixed on the drive wheel 72.Bearing 73 closely cooperates with eccentric wheel 74, and bearing 73 is positioned at drive wheel 74 inboards.Eccentric wheel 74, bearing 73 and drive wheel 72 all are arranged in the internal cavities of base 4, and base 4 is provided with side cover plate 41, and 4 screws 42 of side cover plate 41 usefulness are fixed on the base 4.
When motor 7 rotates, drive eccentric wheel 74 rotations, it is reciprocating that bearing 73 drives drive wheel 72, drive wheel 72 traction elastomer diaphragms 6 are agitated up and down, the seal air cavity internal air pressures that elastomer diaphragm 6 and two one way stop peturn valves 51 and 52 are surrounded change, gas enters and 12 discharges from the air outlet from suction port 11, owing to be provided with one way stop peturn valve 51 and 52, can realize the inflation and the two kinds of functions of bleeding.
Above-mentioned is an embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all belongs to the behavior of invading the utility model protection domain.
