Embodiment

Below in conjunction with drawings and Examples, the utility model is described in more detail.

The utility model discloses a kind of variable capacity high pressure blower, as shown in Figure 1, within this blower includes housing 1 and is located at this housing 1 and parallel the first rotating shaft 2 and the second rotating shaft 3 arranged, bonded to each other and the two reciprocating rotation in the opposite direction in the surface of described the first rotating shaft 2 and the second rotating shaft 3, described the first rotating shaft 2 is extended with the first blade 20 to housing 1 direction, described the second rotating shaft 3 is extended with the second blade 30 to housing 1 direction, described the first rotating shaft 2, the first blade 20, the second rotating shaft 3 and the second blade 30 are divided into the first space 4 and second space 5 by housing 1, described housing 1 is provided with the first breather check valve 40 and the first outgassing nonreturn valve 41 be connected with this first space 4, also be provided with the second breather check valve 50 and the second outgassing nonreturn valve 51 that are connected with this second space 5 on this housing 1.

Above-mentioned blower need by motor coordinate other driving mechanisms to drive the first rotating shaft 2 and the second rotating shaft 3 in the opposite direction and in preset angles reciprocating rotation, the working principle of this blower is:

When blower during in the first state, as shown in Figure 3, two rotating shafts drive respectively the first blade 20 and the second blade 30 to lower swing, make the volume in the first space 4 become large and produce negative pressure, under the effect of atmospheric pressure, the first breather check valve 40 conductings, the first outgassing nonreturn valve 41 is closed, make in the first space 4 and be full of air, simultaneously, the volume of second space 5 diminishes and produces higher positive air pressure, under the promotion of this air pressure, the second breather check valve 50 is closed, and the second outgassing nonreturn valve 51 conductings are also discharged high pressure draught;

When blower during in the second state, as shown in Figure 4, two rotating shafts drive respectively the first blade 20 and the second blade 30 upwards to swing, make the volume in the first space 4 diminish and produce higher positive air pressure, under the promotion of this air pressure, the first breather check valve 40 is closed, the first outgassing nonreturn valve 41 conductings are also discharged high pressure draught, simultaneously, the volume of second space 5 becomes large and produces negative pressure, under the effect of atmospheric pressure, and the second breather check valve 50 conductings, the second outgassing nonreturn valve 51 is closed, and makes in second space 5 and is full of air;

Lasting driving by power mechanisms such as motor, make the first outgassing nonreturn valve 41 and the second outgassing nonreturn valve 51 alternately export high pressure draught, in practical application, the first outgassing nonreturn valve 41 and the second outgassing nonreturn valve 51 can be exported separately high pressure draught, also can will after the two parallel connection, export high pressure draught by pipeline and one-way valve.

In the present embodiment, offer the first air port 42 on described housing 1, described the first breather check valve 40 and the first outgassing nonreturn valve 41 all are connected with this first air port 42, offer the second air port 52 on described housing 1, described the second breather check valve 50 and the second outgassing nonreturn valve 51 all are connected with this first air port 52, based on said structure, only need offer the first air port 42 and the second air port 52 on housing 1, make housing 1 there is better tightness.It should be noted that the above-mentioned setting about air port, is a preferred embodiment of the present utility model, be not limited to the utility model, in other embodiments of the present utility model, housing 1 can offer four air ports, and above-mentioned four one-way valves are installed on respectively place, four air ports.

In order to realize better the first rotating shaft 2 and the second rotating shaft 3 reciprocating rotation in the opposite direction, an end of described the first rotating shaft 2 is arranged with the first gear 21 through housing 1 and this end, an end of described the second rotating shaft 3 is arranged with the second gear 31 through housing 1 and this end, described the first gear 21 and the second gear 31 are intermeshing, in practical application, only need to drive the first gear 21 or the second gear 31 reciprocating rotation in preset angles, just can realize the first blade 20 and the second blade 30 upwards or to lower swing, thereby realize the volume-variation of the first space 4 and second space 5.

The disclosed variable capacity high pressure blower of the utility model, reciprocating rotation by the first rotating shaft 2 and the second rotating shaft 3, drive that the first blade 20 and the second blade 30 synchronously upwards swing or to lower swing, make the volume of the first space 4 and second space 5 change, and the first outgassing nonreturn valve 41 and the second outgassing nonreturn valve 51 are alternately exported high pressure draught.This blower is compared existing centrifugal blower, without a plurality of wider impellers, only need to control the swing speed of the first blade 20 and the second blade 30, just can adjust easily the flow of output pressure, thereby be applicable to the different requirements of user to air mass flow.Simultaneously, this blower fan structure is simple, be easy to realize, thereby has lower product cost.In addition, this blower, by driving the first gear 21 or the second gear 31 reciprocating rotations can change the volume-variation of the first space 4 and second space 5, is convenient to mate driving mechanism.By test, learn, the disclosed variable capacity high pressure blower of the utility model, its exhaust pressure is large, overcomes pullback capacity strong, is particularly suitable for the long occasion apart from air-flow conveying and high-pressure jet.

The above is the utility model preferred embodiment, is not limited to the utility model, all modifications of making in technical scope of the present utility model, is equal to and replaces or improvement etc., all should be included in the scope that the utility model protects.
