The utility model discloses an aim includes, for example, provides a big amount of wind blowing pipe combination, improves the not enough of prior art, promotes the blowing pipe export amount of wind through improving the blast pipe structure, and then promotes the pneumatic extinguisher operation effect.
The utility model discloses an embodiment is realized like this:
the utility model adopts the technical proposal that:
a large-air-volume blowing pipe combination comprises a spray pipe and a spray pipe outer cover, wherein the spray pipe and the spray pipe outer cover are connected together in a front-back mode, and a plurality of air guide channels are arranged on the spray pipe; the air outlet of the spray pipe outer cover is positioned in front of the air outlet of the spray pipe, and the diameter of the air outlet of the spray pipe outer cover is larger than that of the air outlet of the spray pipe;
the spray pipe and the spray pipe outer cover are matched to form an annular air cavity, the annular air cavity is communicated with the spray pipe air outlet and the air guide channel, and two ends of the air guide channel are respectively communicated with the atmosphere and the annular air cavity.
Preferably, the air guide channels are uniformly distributed by taking the axis of the air outlet of the spray pipe as the center.
Preferably, the spray pipe is provided with a first limiting boss and a guide bulge, and the spray pipe outer cover is provided with a guide groove and a second limiting boss which are matched with the spray pipe outer cover.
The utility model has the advantages that compared with the traditional straight barrel or conical barrel blowpipe, the large air volume blowpipe combination of the utility model can effectively extract the external environment air and remit into the air outlet and then be sprayed out together, has the advantages of large outlet air volume, high operation efficiency and the like, and effectively solves the defect of low outlet air volume of the traditional blowpipe; and the spray pipe outer cover are connected and positioned by adopting the guide and limit structures arranged on the spray pipe and the spray pipe outer cover, and the spray pipe outer cover can be installed in place by pressing in the direction parallel to the axis direction of the spray pipe.

Detailed Description
As shown in fig. 1 to 4, the large-air-volume blowpipe combination comprises a blowpipe 1 and a blowpipe outer cover 2.
The spray pipe 1 is provided with a spray pipe air outlet 4, an air inlet 7, a plurality of air guide channels 3, a plurality of first limiting bosses 8 and a plurality of guide bulges 9;
preferably, the air guide duct 3 is generally designed as a U-shaped groove, and can also be designed into other shapes such as square, V-shaped, arc-shaped and the like which can realize the same function according to the requirement;
preferably, the air guide channels 3 are uniformly distributed by taking the axis of the spray pipe air outlet 4 of the spray pipe as the center.
Preferably, the first limiting boss 8 and the guide boss 9 are generally designed to be rectangular bosses, and can also be designed to be arc-shaped, trapezoid-shaped or other shapes capable of realizing the same function according to requirements;
preferably, the number of the first limiting bosses 8 is the same as that of the guide bosses 9.
The spray pipe outer cover 2 is provided with a spray pipe outer cover air outlet 5, a plurality of guide grooves 10 and a plurality of limiting bosses II 11;
preferably, the number of the guide grooves 10 is the same as that of the second limit bosses 11.
Preferably, the number of the guide grooves 10 and the number of the limiting bosses 11 are the same as the number of the limiting bosses 8 and the number of the guide protrusions 9.
The spray pipe outer cover air outlet 5 is located in front of the spray pipe air outlet 4, and the diameter of the spray pipe outer cover air outlet 5 is larger than that of the spray pipe air outlet 4.
