Above-mentioned air vent directly is opened on the top cover.
Above-mentioned air vent directly is opened on the bearing, and the edge of air bag group and the edge of compressing tablet all form the vent of the air-inlet cavity of the air vent that is communicated with bearing and top cover.
Above-mentioned breather cheek valve is person of low position's head shapes (comprising semilune), forms a circular hole at the edge of air bag group, and the breather cheek valve of person of low position's head shapes is connected in the corresponding circular hole.
Above-mentioned unidirectional gas outlet valve is umbrella shape, the air outlet hole of compressing tablet be distributed in a fixed hole around, the handle of umbrella of the unidirectional gas outlet valve of umbrella shape partly is plugged in the fixed hole, umbrella cover then covers on the air outlet hole of compressing tablet.
After adopting said structure, the utility model compared with prior art because breather cheek valve is formed on the edge of air bag group, simplifies the structure, and has reduced member, so production and assembly are more convenient.And, the utility model because breather cheek valve be and the air bag group one, working state is to be affixed on the compressing tablet, so just can freely select top or bottom air inlet for use, the air vent of intake method can place top or bottom as required, structure has more practicability.

Embodiment
As shown in Figure 1, 2, be the embodiment one that the utility model discloses, inflating pump is made up of housing 1, motor 2, cam 3, bearing 4, air bag group 5, compressing tablet 6, breather cheek valve 9, top cover 8 and unidirectional gas outlet valve 7.
Wherein, motor 2 is installed in the housing 1.
Cam 3 is installed on the transmission shaft (among the figure not label) of motor 2.
4 of bearings are on housing 1.
More than be and existing inflating pump resemblance, improvement of the present utility model is:
The end face of bearing 4 forms gas guide groove 41.
The corresponding gas guide groove 41 in the edge of air bag group 5 forms aperture 51 and breather cheek valve 9.Breather cheek valve 9 is person of low position's head shapes (comprising semilune) for good, promptly forms a circular hole 91 at the edge of air bag group 5, and the breather cheek valve 9 of person of low position's head shapes is connected in the corresponding circular hole 91.
On the compressing tablet 6 in the corresponding air bag group 5 position of air bag 52 form pore 62, the position of corresponding air bag group 5 edge breather cheek valves 9 forms inlet hole 61, the aperture 51 of the corresponding air bag group 5 in the bottom surface of compressing tablet 6 and air bag 52 form gas transmission grooves 63.
When this embodiment one uses, gas upwards is advanced in the air-inlet cavity 81 of top cover 8 through vent 53, vent 65 by air vent 42, then, successively through the inlet hole 61 of compressing tablet 6 and breather cheek valve 9 to descending, through gas guide groove 41 commutations of bearing 4, enter air feed in the air bag 52 through the aperture 51 of air bag group 5 and the gas transmission groove 63 of compressing tablet 6, air bag group 5 is alternately inflated, make gas more successively in the air outlet hole 62 of compressing tablet 6, outlet chamber 82 that unidirectional gas outlet valve 7 enters top cover 8, in outlet chamber 82, compile the back and squeeze in the inflatable object, realize inflation by air-inflating tube 83.
Shown in Fig. 3,4, be the embodiment two that the utility model discloses for another example, inflating pump still is made up of housing 1, motor 2, cam 3, bearing 4, air bag group 5, compressing tablet 6, breather cheek valve 9, top cover 8 and unidirectional gas outlet valve 7.This embodiment and embodiment's two difference is: air vent 84 directly is opened on the top cover 8.When this embodiment two uses, gas is directly entered in the air-inlet cavity 81 of top cover 8 by air vent 84, then, successively through the inlet hole 61 of compressing tablet 6 and breather cheek valve 9 to descending, through gas guide groove 41 commutations of bearing 4, enter air feed in the air bag 52 through the aperture 51 of air bag group 5 and the gas transmission groove 63 of compressing tablet 6, air bag group 5 is alternately inflated, make gas more successively in the air outlet hole 62 of compressing tablet 6, outlet chamber 82 that unidirectional gas outlet valve 7 enters top cover 8, in outlet chamber 82, compile the back and squeeze in the inflatable object, realize inflation by air-inflating tube 83.
Combination outward appearance of the present utility model as shown in Figure 5.The utility model compared with prior art because breather cheek valve 9 is formed on the edge of air bag group 5, simplifies the structure greatly, has reduced member, so production and assembly are more convenient.And, because breather cheek valve 9 is one-body molded with air bag group 5, working state is to be affixed on the compressing tablet 6, so, the utility model can freely be selected top (embodiment two) or bottom (embodiment one) air inlet for use, air vent 84 or 42 can be placed top or bottom as required, and structure has more practicability.The utility model is also abandoned the mode of giving vent to anger of thin walled cylinder in the prior art, adopts the unidirectional gas outlet valve 7 of umbrella shape to give vent to anger, and it is more stable to use gas tightness, further avoids gas leak phenomenon.
