As shown in Figure 1, be a kind of electric air pump, the driving component 2 that it mainly comprises motor 1 and is driven by motor 1, driving component 2 connects air bag component 3 ', and air bag component 3 ' comprises air bag 31 ' and eccentric stiffener 32 ', and this driving component 2 ' is arranged in pump case 3 ', in pump case 4, be formed with two air cavitys, i.e. the first air cavity 41 and the second air cavity 42, each air cavity is provided with pore, and air bag component 3 ' is to be placed between two air cavitys; Coordinate shown in Fig. 2 A, 2B, this air bag 31 ' is provided with three air bag nests 311 ', the bottom of each air bag nest 311 ' forms projection 312 ' to be connected with eccentric stiffener 32 ', and the upper surface periphery of each air bag nest 311 ' forms breather cheek valve 313 ', corresponding breather cheek valve 313 ' is provided with inlet hole between two air cavitys, and this breather cheek valve 313 ' is directly on air bag 31 ', to offer crescent shape breach to form; Motor 1 ' drives transmitting assemblies 2 ' motion, promote the 311 ' deformation of air bag nest with continuous pressurized air, make the gas of the first air cavity 31 ' flow out from its pore, when air bag nest 311 ' recovers deformation, the negative pressure of the first air cavity 31 ' is opened breather cheek valve 313 ', make gas flow to the first air cavity 31 ' from the second air cavity 32 ', and then reach the object of bleeding or inflating.
But, air bag 31 ' in this air pump is owing to need to breather cheek valve 313 ' being set at the periphery of air bag nest 311 ' at present, therefore the in the situation that of air bag 31 ' constancy of volume, the opening of air bag nest 311 ' arranges limited, finite volume, and the compressed-air actuated amount of air bag 31 ' is to be determined by air bag nest 311 ', therefore how in the situation that not changing air pump size, effectively improving the decrement of air bag to gas, improve the working efficiency of air pump, is design origin of the present utility model.
Model utility content
The purpose of this utility model is to provide a kind of structure-improved of electric air pump air bag component, and it effectively improves the working efficiency of air pump in the situation that not changing air pump size, improving product performance.
For solving above-mentioned purpose, solution of the present utility model is:
A kind of structure-improved of electric air pump air bag component, this air bag component comprises air bag and the eccentric stiffener with air bag nest, wherein: described air bag nest is formed with flat, on flat, be provided with breather cheek valve, simultaneously air bag nest flat below be formed with for the leg of eccentric stiffener and be nested with cooperation block set, leg is provided with vent.
Described breather cheek valve is to offer the formation of crescent shape breach on flat.
Described air bag is to be provided with three air bag nests.
Adopt after such scheme, because the utility model is incorporated into the breather cheek valve on air bag in air bag nest, be engaged in the vent arranging on eccentric stiffener leg simultaneously, make air bag in the time that air bag nest is set without considering at air bag nest opening reserved to one-way air inlet valve position, can offer to greatest extent the opening of air bag nest, effectively increase the volume of air bag nest, and then improve the working efficiency of air pump, improving product performance.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 4 A, 4B also coordinates Fig. 1, shown in 3, it is a kind of structure-improved of electric air pump air bag component that the utility model has disclosed, as shown in Figure 3, the transmission 2 that this air pump mainly comprises motor 1 and driven by motor 1, driving component 2 connects air bag component 3, air bag component 3 comprises the air bag 31 and eccentric stiffener 32 with three air bag nests 311, three air bag nests 311 to be set describe for example herein, certainly be not limited to three, also can arrange one, two or more air bag nests, this driving component 2 is arranged in pump case 4, and machine shaft 11 is connected with driving component 2 through the axis hole on pump case 4, eccentric rod 21 in driving component 2 is connected on eccentric stiffener 32, in this pump case 4, be formed with two air cavitys, away from the first air cavity 41 of motor and approach the second air cavity 42 of motor, each air cavity is provided with pore, air bag component 3 is to be placed between two air cavitys.
Key of the present utility model is: the air bag nest 311 of described air bag 31 is formed with flat 312, on flat 312, be provided with breather cheek valve 313, this breather cheek valve 313 is on flat 312, to offer crescent shape breach to form, simultaneously air bag nest 311 flat below be formed with block set 314 and be nested with cooperation for each leg 321 of eccentric stiffener 32; And the corresponding each air bag nest 311 of eccentric stiffener 32 is formed with three legs 321, each leg 321 is provided with vent 322.
When air pump described in the utility model is in the time working, power-on starting electrical machinery 1 rotates, motor 1 can drive driving component 2 to move, driving component 2 drives air bag component 3 to move, under the eccentric effect of driving component 2, the eccentric stiffener 32 that promotes air bag component 3 moves up and down, in the time that eccentric stiffener 32 moves up, each leg 321 of eccentric stiffener 32 just can push 311 deformation of air bag nest, gas in air bag nest 311 is pressed in the first air cavity 31, meanwhile, upper surface and the air bag 312 of each leg 321 of eccentric stiffener 32 are fitted, breather cheek valve 313 is now in closed condition, in the time that eccentric stiffener 32 moves down, each leg 321 upper surfaces of eccentric stiffener 32 depart from the close contact with air bag nest 311 flat 312, under the suction function that now recovers to form at air bag nest 311, breather cheek valve 313 is in open mode, and gas enters the gas transport of carrying out next action air bag nest 311 from the second air cavity 42 through the vent 322 of eccentric stiffener 32.
