Description
Technical field
The utility model relates to air pump field, particularly relates to a kind of micro air pump.
Background technique
Generally speaking, micro air pump, at electric breast pump, the products such as personal nursing is all widely used, and in order to carry fluid (being generally gas), and carries out inflation work.Replace by this with the running of manpower inflation, and save time and muscle power.The working principle of existing air pump: the circular movement of motor, the barrier film of pump inside is made to do reciprocatory motion by mechanical device, thus the air in the pump chamber of fixed volume is compressed, draw to stretch and be split into vacuum (malleation/negative pressure), pressure difference is produced at pump bleeding point place and external atmosphere pressure, under the effect of pressure difference, by valve, gas pressure (suction) is entered pump chamber, then discharge from relief opening.Claimant in actual use, find that existing micro air pump is for Exhaust Gas uninterrupted, certain proportional relation is there is with product design volume, and the noise ratio that large discharge air pump produces is larger, for the small household appliances industry articles for use that current noise requirements is higher, low noise product just can not disturb life at home.For household medical product and medical medical product, not only there is requirement to the noise of product, to also requiring the use that can have the longer time working life.
Model utility content
The utility model provides a kind of micro air pump, has volume little, increases the service life, the advantage that noise reduces.
The purpose of this utility model is achieved through the following technical solutions:
A kind of micro air pump, this micro air pump forms by passing through upper cover, valve plate, leather cup, cylinder body, rocker, eccentric wheel, bottom and the motor that long screw is fixedly connected with, it is characterized in that: upper tops is provided with air outlet hole, silencing cotton is provided with between upper cover and valve plate, the top of silencing cotton and air outlet hole are assembled, upper cover (1) and valve plate (2) are assembled and are done Supersonic welding and form tube sealing road, in the hole of valve plate top surrounding, umbrella fourth is installed, leather cup, cylinder body and rocker assembled end; Eccentric wheel is installed between rocker and bottom, and eccentric crown center is provided with inclined hole, in inclined hole, be placed with steel ball, and one end of draw point connects in the middle of rocker, and the steel ball in the other end of draw point and inclined hole is slidably connected; Eccentric bottom is the design of D groove, and the motor shaft at motor top is D axle, and eccentric wheel is coordinated with motor shaft by D groove to be installed, and is provided with sealing gasket, is provided with suction port down below bottom between eccentric wheel and motor shaft.
Compared with prior art, the utility model at least has the following advantages:
By above-mentioned the technical solution of the utility model, because motor adopts the design of D axle, and the eccentric wheel coordinated with it is also the design of D groove, therefore improves the friction when motor runs up, and reduces skidding and causes product function to lose efficacy.In addition, silencing cotton and upper cover outlet nozzle are assembled, and add the noise-reducing gas circuit of upper cover uniqueness, reduce the pneumatic noise that outlet nozzle produces, and air inlet, by air inlet below bottom, reduces charge air flow noise, can assemble baffler and silencing cotton simultaneously, play noise-reducing effect.

Fig. 2 is the superstructure schematic diagram in a kind of micro air pump of providing of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model, be clearly and completely described the technological scheme in the utility model, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-Figure 2, for a kind of micro air pump that the utility model embodiment proposes, this micro air pump is by the upper cover 1 passing through long screw and be fixedly connected with, valve plate 2, leather cup 3, cylinder body 4, rocker 5, eccentric wheel 6, bottom 7 and motor 8 form, it is characterized in that: upper cover 1 top is provided with air outlet hole 11, silencing cotton 9 is provided with between upper cover 1 and valve plate 2, top and the air outlet hole 11 of silencing cotton 9 are assembled, upper cover (1) and valve plate (2) are assembled and are done Supersonic welding and form tube sealing road, in the hole of valve plate 2 top surrounding, umbrella fourth 10 is installed, leather cup 3, cylinder body 4 and rocker 5 assembled end, eccentric wheel 6 is installed between rocker 5 and bottom 7, and the crown center of eccentric wheel 6 is provided with inclined hole, is placed with steel ball 12 in inclined hole, and one end of draw point 13 connects in the middle of rocker 5, and the steel ball 12 in the other end of draw point 13 and inclined hole is slidably connected, the bottom of eccentric wheel 6 is the design of D groove, and the motor shaft at motor 8 top is D axle, and eccentric wheel 6 is coordinated with motor shaft by D groove to be installed, and is provided with sealing gasket 14, is provided with suction port 71 down below bottom 7 between eccentric wheel 6 and motor shaft.
Be described as follows below in conjunction with the working procedure of accompanying drawing to this device:
Motor 8 is energized and runs, and drive motor axle rotates, and is then with movable eccentric wheel 6 to rotate, and rocker 5, draw point 13 insert in eccentric wheel 6 inclined hole with steel ball 12, make leather cup 3 eccentric motion back and forth; When leather cup 3 moves downward, umbrella fourth 10 is opened by the air inlet of bottom 7 inlet hole 71 under negative pressure state, enter in leather cup 3, when being moved upward by leather cup 3 again, pressure is by gas inject valve plate 2 hole, now umbrella fourth 10 is closed by upwards gas pressure, and gas is discharged by upper cover 1 air outlet hole 11 again, so circulates.Gas circuit is successively from bottom 7--leather cup 3--valve plate 2--umbrella fourth 10--silencing cotton 9--upper cover 1, and air pump reduces noise through silencing cotton 9 and unique gas circuit design (Fig. 2) of upper cover 1.Motor 8 is the design of D axle, and the eccentric wheel 6 coordinated with it is also the design of D groove, improves the friction when motor runs up, and reduces skidding and causes product function to lose efficacy, prolongation product working life.
Compared with prior art, the utility model at least has the following advantages:
By above-mentioned the technical solution of the utility model, because motor adopts the design of D axle, and the eccentric wheel coordinated with it is also the design of D groove, therefore improves the friction when motor runs up, and reduces skidding and causes product function to lose efficacy.In addition, silencing cotton and upper cover outlet nozzle are assembled, and add the noise-reducing gas circuit of upper cover uniqueness, reduce the pneumatic noise that outlet nozzle produces, and air inlet, by air inlet below bottom, reduces charge air flow noise, can assemble baffler and silencing cotton simultaneously, play noise-reducing effect.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
