Shown in Fig. 3,4, be the preferred embodiment one that the utility model discloses, the noise reduction 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.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.
Improvement emphasis of the present utility model is:
Between the outlet chamber 82 of top cover 8 and air-inflating tube 83, be provided with silencer.
In Fig. 3,4 illustrated embodiments one, this silencer comprises conduit 84 and guide groove 66.Conduit 84 is formed by air-inflating tube 83 direct extension in outlet chamber 82, and conduit 84 specifically may extend to the end face of compressing tablet 6, and the bottom of conduit 84 can weld together by the end face of ultrasound and compressing tablet 6.Guide groove 66 is formed on the end face of compressing tablet 6, and guide groove 66 plays a part to be communicated with outlet chamber 82 and conduit 84.
Like this, when this embodiment uses, gas by air vent 42 through vent 53, vent 65 upwards is advanced in the air-inlet cavity 81 of top cover 8, then, successively through the inlet hole 61 of compressing tablet 6 and breather cheek valve 9 to descending, gas guide groove 41 commutations through 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 successively through the air outlet hole 62 of compressing tablet 6 again, unidirectional gas outlet valve 7 enters in the outlet chamber 82 of top cover 8, after in outlet chamber 82, compiling, gas is again through guide groove 66, conduit 84 bufferings, squeeze in the inflatable object by air-inflating tube 83, realize inflation.
Fig. 5, the 6th, embodiment two of the present utility model, the structure of its 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 is identical with embodiment one, describes referring to embodiment one structure.This embodiment and embodiment's one difference is that silencer comprises conduit 84 and square groove 85 (replacing the guide groove 66 among the embodiment one); Conduit 84 is still formed by air-inflating tube 83 direct extension in outlet chamber 82; Square groove 85 is opened on the tube wall of conduit 84, is communicated with outlet chamber 82 and conduit 84.When this embodiment used, the gas that enters top cover outlet chamber 82 was through square groove 85, conduit 84 bufferings, noise reduction, again by air-inflating tube 83 output inflations.
Fig. 7, the 8th, embodiment three of the present utility model, the structure of its 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 is identical with embodiment one, describes referring to embodiment one structure.This embodiment and embodiment one difference are the little air cavitys that the outlet chamber 82 corresponding unidirectional gas outlet valves 7 with top cover are divided into corresponding number, are interconnected, three unidirectional gas outlet valves 7 are arranged among this embodiment, outlet chamber 82 also just is divided into three little air cavitys that are interconnected, concrete air-flow trend so also can be passed through stingy chamber buffer gas flow referring to embodiment one.In addition, the outlet chamber 82 of top cover also can be as shown in figure 13, the little air cavity that corresponding unidirectional gas outlet valve 7 is divided into corresponding number, is interconnected, three little air cavitys that are interconnected are arranged among this embodiment, also have three silencing cavity 821 between three little air cavitys, concrete air-flow trend so also can be passed through silencing cavity 821 buffer gas flows referring to embodiment one, further reaches the noise reduction effect.
Fig. 9 is embodiment four of the present utility model, and the structure of its 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 is identical with embodiment one, describes referring to embodiment one structure.This embodiment and embodiment's one difference is that bloop 86 is installed in conduit 84.The concrete structure of bloop 86 can be rounded shown in Figure 10,11, has bloop 861 on the circle bloop 86, and bloop 861 can be circular hole or arcuate socket; Bloop 86 also can be rounded as shown in figure 12, and noise reduction breach 862 is offered at the edge of circle bloop 86.This bloop 86 also can be installed in embodiment's two, three described conduits 84.Like this, air-flow when the conduit 84, more thus the bloop of bloop 86 or noise reduction breach further cushion, noise reduction.
The utility model compared with prior art owing to before air-inflating tube 83, set up noise reduction Device makes air-flow obtain buffering through silencing means, and air-flow is steadily and not rapid, greatly disappears thus Except inflating noise, result of use is better. Simultaneously, because breather cheek valve 9 is formed on gas On the edge of capsule group 5, greatly simplify the structure, reduced member, so production and assembly more Convenient. And because breather cheek valve 9 is one-body molded with air bag group 5, duty is The utility model is affixed on the compressing tablet 6, so can freely select top or bottom (to see this reality Execute example) air inlet, air vent 42 can be placed top or bottom as required, structure has more reality The property used. The utility model is also abandoned the mode of giving vent to anger of thin cylinder in the prior art, adopts umbrella shape Unidirectional air outlet valve 7 is given vent to anger, and it is more stable to use gas tightness, further avoids gas leak phenomenon.
