Problems solved by technology

However, the wind impeller of this fire extinguisher is a cast integral structure, not only the fastness is not enough, the cast impeller is easy to break, and the fragments are very easy to hurt people, and it is limited by the mold during casting, and the air outlet angle of the wind blade will be limited. Due to the limitation, the wind effect is not ideal, and the carrying weight of the fire extinguisher is relatively large, which will increase the carrying burden of firefighters, so this structure needs further improvement

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 8 As shown, the wind fire extinguisher of the present embodiment includes an engine 10, a body 5, a starting part 3, a handle part 2 arranged on the body 5, a cooling wind part and an impeller of the jetting wind part 4, on the left and right sides of the body 5 A cooling wind part and a blowing wind part 4 are provided, and the blowing wind part 4 communicates with the airflow spraying tube 1, and the wind impeller 43 of the blowing wind part 4 and the outer fixing ring 42 are fixed together by bolts.

[0026] The specific structure that the wind impeller 43 of the above-mentioned blowing wind part 4 and the outer fixed ring 42 are fixed to each other by bolts is as follows: on the corresponding curved wind piece 431 on the same circumferential surface of the wind impeller 43, axially protruding bosses are distribute...

Abstract

The invention relates to a pneumatic extinguisher which comprises an engine (10), an extinguisher body (5), a starting part (3), a handle part (2) arranged on the extinguisher body (5), a cooling air part and an impeller of an injection air part (4), wherein the cooling air part and the injection air part (4) are arranged at the left and right sides of the extinguisher body (5), and the injection air part (4) is communicated with an airflow injection barrel (1). The pneumatic extinguisher is characterized in that the impeller (43) of the injection air part (4) and a fixing ring (42) arranged at the outer side are fixed together by bolts. The pneumatic extinguisher has the advantages of the impeller and the fixing ring are combined in a split manner so that the impeller is firmer and has longer service life; and the cooling air part can effectively prevent foreign matters and dust from entering air ducts, thereby avoiding part wear and faults such as high temperature caused by the blockage of the air ducts, protecting the engine from generating high temperature and being burnt out because external air cannot pass through the air ducts, and effectively prolonging the service life of the pneumatic extinguisher.

Description

technical field [0001] The invention relates to the technical field of making a fire extinguisher, in particular to a wind-powered fire extinguisher. Background technique [0002] Existing a kind of patent No. is that 92106498.5 name is called " a kind of forest fire extinguisher " Chinese invention patent discloses a kind of forest fire extinguisher, and its structure comprises a knapsack type fire extinguishing agent storage container and blast jet, between the two with a Elastically bendable tube connections. There is a damper on the blower injector, double impellers are installed in the air-inducing drum, and there is an anti-blocking dredging device, and the nozzle is duckbill-shaped. The fire extinguisher has a large amount of charge and a good fire extinguishing effect. However, the wind impeller of this fire extinguisher is a cast integral structure, not only the fastness is not enough, the cast impeller is easy to break, and the fragments are very easy to hurt peo...
