Description

The high-voltage electric air pump

Technical field

The utility model relates to a kind of high-voltage electric air pump, specifically, and the less high-voltage electric air pump of noise when being meant a kind of the running.

Background technique

High-voltage electric air pump in the market mainly contains two kinds of structures, and a kind of is conventional pump, adopts direct air inlet, the mode air feed of directly giving vent to anger.As shown in Figure 5, the two ends of one tube-like envelope 60 are assembled with protecting cover 61,62, form suction port 63 and air outlet 64 respectively in these two protecting covers, 61,62 central authorities, on the direction of tube central shaft, assemble first blade 65, second blade 66 and a motor 67 simultaneously, and be separated out first vane room 68, second vane room 69 and motor room 70 by dividing plate.Driving two blades 65,66 when motor 67 runnings rotates, ambient air can be imported in first vane room 68, push towards periphery by centrifugal force then, make air enter second vane room 69 and motor room 70 successively, send by the air outlet 64 of tube-like envelope 60 the other ends at last.Though this air pump can reach the purpose of high-pressure air feed, but the noise of motor is excessive, causes suitable severe noise to pollute, and influences staff's proper functioning;

Another kind of air pump is that Chinese patent application number is 00255071.7 disclosed high-voltage electric pump, as shown in Figure 4, it is provided with suction port 41 and air outlet 42 on a cylindrical case 40, and at cylindrical case 40 sides formation side neck, in this side neck, form air pipe, be assembled with protecting

cover

43,44 at shell 40 two ends, and form the

inboard air chamber

45,46 of protecting cover; Assemble a motor 47 in the inboard of tubular body 40, and assemble first blade 48, second blade 49, and be separated out motor room 50 and first vane room 51, second vane room 52 by dividing plate in a side of the axle of motor 47.When motor 47 runnings, air enters motor room 50 by suction port 41, and be directed to the inboard air chamber 46 of the other end protecting cover by the air pipe that the inboard air chamber 45 of protecting cover enters side neck, and enter first vane room 51, second vane room 52 then, send by air outlet 42 at last.This high-voltage electric pump, though air can make the noise of motor reduce in repeatedly bending process, the mode of directly giving vent to anger is adopted in the air outlet, still has the excessive shortcoming of noise in actual the use, is necessary further to be improved.

Summary of the invention

The purpose of this utility model is the excessive defective of noise when overcoming existing high-voltage electric air pump running, thereby a kind of improved high-voltage electric air pump is provided.

For reaching above-mentioned purpose, high-voltage electric air pump of the present utility model comprises a cylindrical case, forms side neck respectively at this cylindrical case upside and downside, forms air pipe in this side neck, and the air pipe of upside is a steam outlet pipe, and the air pipe of downside is a suction tude.Two ends at cylindrical case are assembled with protecting cover, at one end protecting cover is provided with a suction port, an air outlet and leader, forms the inboard air chamber of protecting cover between this two ends protecting cover and the cylindrical case, wherein, suction port communicates with the inboard air chamber of front end protecting cover, and the air outlet communicates with the air pipe of upside side neck.In cylindrical case, be provided with a motor, and be provided with fan II, gas chamber clapboard, fan I and air chamber housing in regular turn, can form motor room, first, second air chamber thus in a side of this motor shaft.

When motor operation, can drive fan rotates, and the air in the external world is sucked the inboard air chamber of protecting cover by suction port, and enter the motor room by the inboard air chamber of protecting cover, then, air enters the inboard air chamber of protecting cover of the other end via the suction tude of cylindrical case downside, enters first air chamber, second air chamber more successively, at last deliver to the air outlet, discharge air pump via the steam outlet pipe of cylindrical case upside.

The beneficial effects of the utility model are: this high-voltage electric air pump increases the path of air turnover air pump via reasonably adjusting on the structure, reaches the purpose of effective reduction electric moter noise thus.
