The utility model provides a technical scheme that its technical problem adopted is: the foam nozzle capable of expanding by impact comprises a nozzle and a nozzle connector, wherein the nozzle connector is fixedly connected to the right end of the nozzle, flow channels are formed in the four sides of the right end of the nozzle connector, the front side and the rear side of the right end of the nozzle connector are provided with inner cavities, a communicating channel is formed between each flow channel and each inner cavity, and air guide holes are formed in the four ends of the nozzle, namely the front end, the rear end and the front end.

In the technical scheme, the outer wall of the nozzle connecting body is provided with threads, and the right side of the nozzle connecting body is connected with a fire extinguisher spray pipe through the threads in a rotating manner.

In the technical scheme, the baffle is adhered to the opening at the left end in the inner cavity through an adhesive, the guide rod is fixed in the middle of the left end of the baffle, and the outer side of the left end of the baffle is uniformly provided with at least four discharge holes in an annular shape.

In the above technical scheme, the baffle and the guide rod are both made of plastics.

In the technical scheme, the height of the communicating channel is 1mm-3 mm.

In the above technical solution, the flow passage, the communication passage and the inner cavity are communicated with each other.

Compared with the prior art, the utility model discloses the beneficial effect who realizes: this kind of foam nozzle who utilizes impact expansion, because nozzle connector right-hand member is opened has four independent runners for when fluid passes the intercommunication way along the runner, can discharge this great space of inner chamber, the fluid through mutual collision takes place the split in the twinkling of an eye, makes the fluid become tiny granule, then through the air guide hole, makes the granule disperse and separates, the shower nozzle jet is become by countless granule like this, rather than a post rivers, with this nozzle injection foam when electrified organism, the user can not be counterstruck by the electric current.

Detailed Description

In order to more clearly illustrate embodiments of the present invention or technical solutions in the prior art, specific embodiments of the present invention will be described below with reference to the accompanying drawings. It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be obtained from these drawings without inventive effort.

Referring to fig. 1-2, the present invention provides a technical solution: a foam nozzle expanded by impact comprises a nozzle 1 and a nozzle connector 3, wherein the nozzle connector 3 is fixedly connected to the right end of the nozzle 1, flow channels 4 are respectively arranged on the upper, lower, front and rear four sides of the right end of the nozzle connector 3, an inner cavity 7 is arranged at the left end of the nozzle connector 3, a communicating channel 6 is arranged between each flow channel 4 and the inner cavity 7, air guide holes 2 are respectively arranged on the upper, lower, front and rear four ends of the nozzle 1, the height of the communicating channel 6 is 1mm-3mm, the flow channels 4, the communicating channels 6 and the inner cavity 7 are communicated, as the four independent flow channels 4 are arranged at the right end of the nozzle connector 3, when fluid is sprayed into the nozzle connector 3 along a spray pipe of a fire extinguisher, the fluid can pass through the communicating channels 6 along the flow channels 4, at the moment, the fluid can be discharged into the space of the inner cavity 7, and the fluid can be, the fluid is changed into fine particles, when the fluid changed into the fine particles is sprayed into the spray head 1 from the inner cavity 7, the fluid is absorbed into a large amount of air through the four air guide holes 2 in the spray head 1 along with the eddy effect of the sprayed flow and enters the spray head 1, the foam particles are instantly amplified at intervals after being impacted by the air, and the foam particles are simultaneously pushed to be sprayed to an outlet at the left end of the spray head 1, so that the sprayed flow of the spray head 1 is composed of numerous particles instead of a column of water flow, gaps exist among the particles, current transmission between the particles is difficult to carry out, and when the spray head sprays the foam to an electrified machine body, a user cannot be counterstruck by the current.
