The content of the invention

For above-mentioned deficiency of the prior art, the utility model provides a kind of impacting type fire-fighting atomizer, has spray Spill the advantages of uniform sprinkling coverage is big.

To achieve these goals, the utility model provides a kind of impacting type fire-fighting atomizer, including a nozzle boss, institute Stating nozzle boss includes a linkage section and a sections of atomization, and the linkage section first end forms a feed liquor connector；The sections of atomization bag Including a straight length and a Taper Pipe section, the first end of the straight length connects the second end of the linkage section, and the of the straight length Two ends connect the first end of the Taper Pipe section；Second end external diameter of the Taper Pipe section is less than the outer of the first end of the Taper Pipe section Footpath, the Taper Pipe section forms multiple first shock spout structures and/or the straight length forms multiple second and hits spout structure, Described first hits spout structure lays along the circumference of the Taper Pipe section；Described second hits spout structure along straight length week To laying.

Preferably, the first shock spout structure includes one first duct, one second duct and one first shock spout, First duct mutually in one first fixed angle and connects the Taper Pipe intersegmental part and described first with second duct Hit spout.

Preferably, the second shock spout structure includes one the 3rd duct, one the 4th duct and one second shock spout, 3rd duct mutually in one second fixed angle and connects the straight length inside and described second with the 4th duct Hit spout.

Preferably, the first shock spout and the second shock spout are interspersed.

Preferably, first fixed angle is 20 ° to 170 °.

Preferably, the second fixed angle is 20 ° to 170 °.

The utility model makes it have following beneficial effect as a result of above technical scheme：

First hits spout structure lays along the circumference of Taper Pipe section so that the impacting type fire-fighting atomizer of the present embodiment Spraying range is more uniformly distributed.The cooperation in the first duct, the second duct and the first shock spout realizes the first shock spout structure Atomized spray, injection uniformly and spray regime it is big.Second, which hits circumference of the spout structure along straight length, lays so that this implementation The spraying range of the impacting type fire-fighting atomizer of example is more uniformly distributed.Second, which hits circumference of the spout structure along straight length, lays, So that the spraying range of the impacting type fire-fighting atomizer of the present embodiment is more uniformly distributed.

Brief description of the drawings

Fig. 1 is the positive structure diagram of the impacting type fire-fighting atomizer of the utility model embodiment；

Fig. 2 is Fig. 1 Section A-A figure；

Fig. 3 is Fig. 1 section B-B figure.

Embodiment

Below according to 1~Fig. 3 of accompanying drawing, preferred embodiment of the present utility model is provided, and is described in detail, is enabled more preferable Ground understanding function of the present utility model, feature.

Refer to Fig. 1~Fig. 3, a kind of impacting type fire-fighting atomizer of the utility model embodiment, including a nozzle boss 1, nozzle boss 1 includes a linkage section 11 and a sections of atomization 12, and the first end of linkage section 11 forms a feed liquor connector 111；Sections of atomization 12 include a straight length 121 and a Taper Pipe section 122, the second end of the first end connection linkage section 11 of straight length 121, straight length The first end of 121 the second end connection Taper Pipe section 122；Second end external diameter of Taper Pipe section 122 is less than the first end of Taper Pipe section 122 External diameter, Taper Pipe section 122 form multiple first shock spout structures 123 and/or straight length 121 and form multiple second shocks spout knots Structure 124, first hits spout structure 123 lays along the circumference of Taper Pipe section 122；Second hits spout structure 124 along straight length 121 It is circumferential to lay.

First hits spout structure 123 lays along the circumference of Taper Pipe section 122, and second hits spout structure 124 along straight length 121 circumferential laying so that the spraying range of the impacting type fire-fighting atomizer of the present embodiment is more uniformly distributed.

Wherein, the first shock spout structure 123 includes one first duct 1231, one second duct 1232 and one first shock Spout 1233, the first duct 1231 and the second duct 1232 mutually in one first fixed angle and connect the inside of Taper Pipe section 122 and First hits spout 1233.In the present embodiment, the first fixed angle is 20 ° to 170 °, in other embodiment, the first fixed angle Also can be adjusted according to being actually needed.

The cooperation in the first duct 1231, one second duct 1232 and one first shock spout 1233 realizes the first shock spray The atomized spray of mouth structure 123, injection is uniformly and spray regime is big.

Second, which hits spout structure 124, includes one the 3rd duct 1241, one the 4th duct 1242 and one second shock spout 1243, the 3rd duct 1241 mutually in one second fixed angle and connects the inside of Taper Pipe section 122 and second with the 4th duct 1242 Hit spout 1243.In the present embodiment, the second fixed angle is 20 ° to 170 °, and in other embodiment, the second fixed angle also may be used Adjusted according to being actually needed.

The cooperation in the 3rd duct 1241, the 4th duct 1242 and the second shock spout 1243 realizes the second shock spout knot The atomized spray of structure 124, injection is uniformly and spray regime is big.

In the present embodiment, the first shock spout 1233 and second hits spout 1243 and is interspersed.In other embodiments, First shock spout 1233 and second, which hits spout 1243, also can be distributed to position correspondence.

The utility model is described in detail above in association with accompanying drawing embodiment, those skilled in the art can root Many variations example is made to the utility model according to described above.Thus, some details in embodiment should not be formed to this practicality New restriction, the utility model will be used as the scope of protection of the utility model using the scope that appended claims define.
