Specific embodiment
As shown in Figure 1, the utility model is the structure that a kind of profile is cylinder, mainly by motor sub-assembly 10, and kinetic energy transfer part 20, press part 30, the air pump of gas collection portion 40 be combined intos, and utilize locking nut 50 in conjunction with fixing.
Kinetic energy transfer part 20 comprises fixed base 201 and rotation section, and wherein the rotation section comprises an eccentric wheel 204, a transmission shaft 205, a bearing 206, a piston 207.
As shown in Figure 2, transmission shaft 205 is connected with piston 207 by bearing 206, avoids transmission shaft 205 to produce wearing and tearing in the running, consume kinetic energy, thereby improve the kinetic energy transmission efficiency, improve air pump working life, and running steadily, the pressurized gas of generation is even.
Please consult simultaneously shown in Fig. 1,3 and 4, gas collection portion 40 comprises umbrella shape safety check 401, pump cover 402, umbrella shape safety check 403, noise lid 404.Wherein, the fixedly trip 4011 at umbrella shape safety check 401 rears snaps in inlet hole 4023, constitutes suction valve.The fixedly trip 4031 at umbrella shape safety check 403 rears snaps in delivery outlet 4021 and constitutes delivery valve.Form after pump cover 402 and the 404 usefulness ultrasonic welding of noise lid by the separated air-breathing and air- storage chamber 4024 and 4025 of giving vent to anger of air-storage chamber dividing plate 4022.Can install air-filtering part (not shown) additional at air inlet nozzle 4041 places according to actual needs, go into the quality of gas to guarantee filter.
Among Fig. 5 with one air-breathing and give vent to anger the action be that example describes.When gas enters air inlet air-storage chamber 4024 by air inlet nozzle 4041, owing to the effect of the inner negative air pressure of air bag, 401 umbrella shape safety check are opened, and 403 umbrella shape closure of check ring are finished aspiratory action; Along with the operation of air bag, internal pressure is changed into positive air pressure thereupon, suction valve closure, and delivery valve is opened, and finishes the action of giving vent to anger.Because umbrella shape safety check 401 and 403 adopts a kind of one-way valve principle, has just avoided gas backstreaming, improve pump gas efficient.Because umbrella shape safety check 403 when giving vent to anger, does not have any collision with pump cover 402, thereby has reduced the noise of air pump.Back elder generation through the air-storage chamber 4025 of giving vent to anger, makes that the gas of output is more even, steadily with gas stream owing to give vent to anger.
When motor sub-assembly 10 runnings, to rotate in conjunction with thereon eccentric wheel 204 thereupon, make transmission shaft 205 rotate thereupon, transmission shaft 205 is subjected to eccentric wheel 204 to rotate each blade oscillating that makes piston 207, and piston continues compression bladder 3021, air bag 3021 is constantly oppressed pressing chamber 3022 regularly, and then produces gas and deliver to gas collection portion 40.And when piston continued compression bladder 3021, suction valve closely cut out by the air pressure inside effect.Delivery valve then is subjected to air bag internal gas thrust and opens, and when treating that air bag 3021 resets, suction valve is opened, and the gas in the air inlet air-storage chamber 4024 is sucked in the air bag 3021 via suction valve, and delivery valve then is subjected to the inner negative air pressure effect of air bag and closely cuts out.Persistent movement in the cause of air bag 3021 gas inside because of the lasting extruding of air bag, is transported to air-storage chamber 4024 backs of giving vent to anger with gas via delivery valve equably and is evenly sprayed by gas delivery outlet 4021 and so forth.
Improved each one of the utility model adopts screw locking, makes that the connection of each one is easier, and is reliable.And gas collection portion 40, press part 30, kinetic energy transfer part 20 uses screws 50 to connect, and makes that the position of each one is more stable relatively, connects compacter.
The utility model has more except that having above-mentioned advantage:
1. on profile, volume, can suit measures to local conditions.
2. the volume of air-storage chamber can design as required.
3. the use of noise lid and delivery valve, can guarantee pressurized gas with the noise that reduces air pump, the using scope of raising air pump.
Above-mentioned detailed description is at the specifying of the feasible preferred embodiments of one of this use type, but this example is not in order to limit scope of patent protection of the present utility model.
