The utility model provides a fire control atomizing nozzle has good atomization effect and spraying range far away on this fire control atomizing nozzle, and the nozzle mouth on this fire control atomizing nozzle is cleaned and is sealed under non-user state to guarantee the cleanness of nozzle mouth, further improve fire extinguishing efficiency.

The fire-fighting atomizing nozzle at least comprises a nozzle body and a cleaning component 40 movably arranged on the nozzle body, wherein the nozzle body comprises a nozzle connecting pipe 10 and a flow guide tongue 30 which are connected with each other, and a filter screen 20 arranged at the connecting position of the nozzle connecting pipe 10 and the flow guide tongue 30, the flow guide tongue 30 further comprises a flow guide pipe 31, a screw rod 32 arranged in the flow guide pipe 31 and a nozzle opening 33 arranged at the outlet end of the flow guide pipe 31, and the nozzle opening 33 comprises a first nozzle 331 and a second nozzle 331 which are connected with each other to form an X-shaped cross section; one end of the cleaning assembly 40 is disposed within the second nozzle 331 when the nozzle body is not in use.

In use, the nozzle connection pipe 10 is connected with a fire hose, and water in the fire hose can enter the diversion tongue 30 through the nozzle connection pipe 10 and be sprayed out of the nozzle opening 33 of the diversion tongue 30.

In order to improve the atomization effect of water mist and reduce the energy loss of the fire extinguishing agent on the flow guide tongue 30, the spiral rod 32 is arranged in the flow guide pipe 31 in a sliding mode, a spiral flow channel is formed by the spiral rod 32 and the inner wall of the flow guide pipe 31, water flow entering the flow guide tongue 30 is sprayed by rotational flow and is refined into water mist, and the atomization effect of the fire-fighting atomization nozzle is improved.

As shown in fig. 3, the screw 32 further includes a rod tube 321 and a spiral groove side 322 disposed on the circumference of the rod tube 321, wherein the spiral groove side 322 is disposed in the same direction, the rod tube 321 has a smaller cross-sectional size than the draft tube 31, and the screw 32 has a cross-sectional size matching the cross-sectional size of the draft tube 31. The spiral groove edge 322 can be selected to be various patterns, and in an embodiment of the present invention, the spiral groove edge 322 is selected from one of a rectangular spiral groove edge, a sawtooth spiral groove edge, and a circular arc spiral groove edge. In other embodiments, the spiral groove edge 322 is provided with a through hole to further enhance the spiral effect.

However, the water mist in the high pressure state in the flow guiding pipe 31 impacts the nozzle opening 33, which not only damages the structural stability of the nozzle opening 33, but also affects the spraying range of the mist. In order to solve the problem, the nozzle opening 33 of the present invention is a combination of a first nozzle 331 and a second nozzle 331, wherein the first nozzle 331 is connected to the flow guide tube 31, the second nozzle 332 is connected to the external environment,

Specifically, the first nozzle 331 is in an inverted funnel shape, that is, the cross-sectional area of the first nozzle 331 is sequentially contracted from bottom to top, so that the cross-sectional area of the water flow is sequentially reduced when the water flow passes through the first nozzle 331, so that the water flow can maintain a laminar flow state.

The second nozzle 332 is in a vertical funnel shape, that is, the cross-sectional area of the second nozzle 332 is sequentially reduced from top to bottom, so that the cross-sectional area of the water flowing through the second nozzle 332 is sequentially increased and the water is sprayed outward with a larger spraying area.

And, the second nozzle 332 is designed into a duckbill shape, that is, the cross section of the connection opening of the second nozzle 332 and the first nozzle 331 is circular, and the cross section of the spraying outlet 3321 of the second nozzle 332 communicating with the external environment is flat and rectangular, at this time, the water flow interface of the water flow passing through the second nozzle 332 is changed from circular to rectangular, which plays the roles of increasing the spraying range of the water mist and promoting the atomization of the water flow.

However, the mist of water will inevitably remain the fire extinguishing agent in the process of spraying through the nozzle opening 33, the fire extinguishing agent will pollute the nozzle opening 33 with the residual powder left after volatilization, and the external dust and powder will also pollute the nozzle opening 33, therefore, the utility model provides a cleaning assembly 40, wherein the cleaning assembly 40 comprises an assembly part 41 arranged on the nozzle body, a hose 42 connected to the assembly part 41 and a cleaning head 43 arranged at one end of the hose 42, wherein the cross-sectional size shape of the cleaning head 42 is the same as the cross-sectional size shape of the second nozzle 332, in particular the cross-sectional size shape of the spraying outlet 3321, and the second nozzle 332 can be sealed to perform the cleaning and sealing functions.

Specifically, the cleaning head 42 is implemented as a cleaning sponge body, and the cleaning sponge body absorbs the water agent on the inner wall of the second nozzle 332, and at this time, the sponge body has a certain humidity, and plays a role in cleaning dust in the process of taking and removing the cleaning head 42.

The assembly 41 is a hollow circular tube disposed on the side of the nozzle body, and the hose 42 is fixed to the assembly 41. Alternatively, the hose 42 is made of a soft material, such as rubber, for example. When the fire-fighting atomizing nozzle needs to be used, the cleaning head 43 can be easily pushed out by the pressure in the flow guide pipe 10, and at the moment, the hose 42 falls down due to the self-weight, so that the water mist spraying of the nozzle opening 33 is not influenced.

The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by the teaching of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as the present invention, fall within the protection scope of the present invention.
