Abstract
The utility model relates to improvement on a power-saving inflation pump. The power-saving inflation pump is characterized in that the rear end of a small cylinder is open; and an air inlet unidirectional valve is arranged at the front end of a large cylinder. Compared with the prior art, the power-saving inflation pump has the advantages that the rear end wall of the conventional small cylinder and the unidirectional valve (of which the rear part is opened to quit working) on the small cylinder are eliminated, so that an air pump is prevented from sucking air from the rear part; the air inlet unidirectional valve is arranged on the front end wall of the large cylinder, so that the air is directly sucked into the air pump from a front end shell; therefore, the power-saving inflation pump is suitable to be used as a mechanically-driven pump and is used in some places with large inflation amount; and the inflation speed and the inflation efficiency are improved. By the power-saving structure of the set cylinder, the required motor power is smaller than that of the common mechanically-driven inflation pump and is only 40 percent or even lower than 40 percent of the motor power of the common mechanically-driven inflation pump; particularly, an air suction unidirectional valve and an air exhaust unidirectional valve adopt staggered hole thin films or metal thin films, so that the response frequency of the unidirectional valve is greatly increased; and the power-saving inflation pump is suitable for mechanical inflation pumps.

Little cylinder piston both can be made hollow structure, and one-way valve is arranged on the inner ring surface, and the central row tracheae is communicated with inner ring surface; Also can little cylinder piston be made single-sided structure, exhaust check valve is arranged at central row tracheae and piston joint.Wherein be preferably and adopt the former hollow structure, help the frequency response of one-way valve, can be fit to the motor pump fast aeration.
Suction, exhaust check valve; Can adopt the one-way valve that various structures have unidirectional conducting function in the existing technology,, make it to adapt to motor pump fast aeration (action is got caught up in) for improving the one-way valve frequency response speed; The one-way valve that a kind of better employing dislocation hole film or sheet metal constitute
Dynamic pressure when further reducing to inflate is poor, and a kind of better is to make that the ventilation cross section became big when one-way valve was opened on the gas-filled pump, for example is preferably ventilation sectional area>=7 ㎝
2, and air pump is big more, and the ventilation sectional area was also big more when one-way valve was opened.The big feasible relatively gas speed through one-way valve in ventilation cross section can reduce like this, thereby it is poor to have reduced dynamic pressure, can be further laborsaving.
The laborsaving gas-filled pump of model utility, with respect to existing technology since leave out former little cylinder aft bulkhead and on one-way valve (rear portion opened is deactivated), stop air pump air-breathing from the rear portion; And set up breather check valve at the vat front bulkhead, make the air pump air inlet directly in the past end housing suck outward, thereby make laborsaving gas-filled pump can be fit to do motor pump, be used for some big aeration quantity occasions, improved aeration speed and efficient.This structure has also reduced the one-way valve consumption, only needs three one-way valves to realize, omits 2 one-way valves more originally.And owing to adopt cover cylinder labor-saving structure, required motor power is also more common, and motor-driven to fill pump little, have only common motor-driven gas-filled pump 40% or lower.Particularly suction, exhaust check valve adopt dislocation hole film or sheet metal, improve the one-way valve response frequency greatly, are more suitable in the mechanical aeration pump.
