Description
Technical field
The utility model relates to a kind of high-pressure mini air pump, and especially a kind of rotor is only established the high-pressure mini air pump of a slice blade.
Background technique
At present centrifugal pump rotor be all multiple-blade structure, although have advantages of that compressive charge frequency is high, aeration speed is fast, because of blade and pump housing inner headed face seal poor, so inflation pressure is low.Therefore require many application that inflation pressure is high, its use is still restricted.
Model utility content
The deficiency existing for existing centrifugal pump, the utility model provides a kind of centrifugal high-pressure mini air pump, and its rotor is only established a slice blade.This high-pressure mini air pump, not only aeration speed is fast, and inflation pressure is also significantly improved.
The technological scheme that the utility model technical solution problem adopts is: a kind of high-pressure mini air pump, is made up of pump case, rotor and motor.Described pump case comprises the pump housing, left pump cover, right pump cover and safety enclosure.On the described pump housing, be provided with compressive charge mouth and intakeport, on intakeport, be provided with air filter.It is characterized in that: on the pump housing inner headed face between described compressive charge mouth and intakeport, be provided with groove, in groove, be provided with partition, limit, partition bottom right contacts with described rotor outer circle face, partition left end be placed in left pump cover and right pump cover on rotating little axle be connected.Little axle left end is connected with spiral arm one end of being located at left pump cover outside, and one end of spiral arm is connected with extension spring one end again, and the other end of extension spring is fixed on left pump cover outer side surface.The described spiral arm the other end is provided with roller; Described rotor is eccentric rotor, is provided with straight trough in its maximum eccentric radius, is provided with blade in straight trough, and blade one end contacts with pump housing inner headed face, and the other end is by the spring supporting of being located in straight trough.Rotor shaft and pump housing inner circle coaxially arrange, supported by left pump cover and right pump cover fixing, rotating shaft left end respectively be located at left pump cover outside, the control wheel contacting with spiral arm the other end roller is connected with balancing rotor piece.Described control wheel is provided with boss.Described safety enclosure is fixed on left pump cover outer side surface.
The beneficial effects of the utility model are: the one, and compressive charge not only frequency is high, and actual volume is large, and the maximum actual volume of its compressive charge almost can reach the actual volume of whole high-pressure mini air pump intracoelomic cavity; The 2nd, contact radius is consistent all the time everywhere with pump housing inner headed face for rotor blade, and contact sealing load size is constant, and contact sealing is reliable.Therefore its supercharging intensity is large, and not only pressurized air speed is fast, and compressive charge pressure is high.
