Embodiment
For detailed description technology contents of the present utility model, the objects and the effects, below in conjunction with embodiment and match somebody with somebody
Accompanying drawing is closed to be explained.
The design of the utility model most critical is：By continuing aerating foam solution with air narrow to shower nozzle inside
Narrow fluid passage is sufficiently mixed.
It refer to Fig. 1 and Fig. 2, a kind of foam nozzle, including nozzle body 1, inner core 2 and air inlet pipe 3, the shower nozzle master
Body 1 is the hollow structure that both ends have opening, and inner chamber, the shower nozzle master are provided between the outer wall and inwall of the nozzle body 1
The outer wall of body 1 is provided with the air inlet pipe 3, and the inwall of the nozzle body 1 is provided with through hole, and the inner core 2 is arranged at described
In the hollow structure of nozzle body 1, the inner core 2 is connected with the nozzle body 1, the inner core 2 and the nozzle body 1
There is space, the space forms fluid passage, and the fluid passage extends respectively to the two of the nozzle body 1 between inwall
The opening at end.
Working mechanism of the present utility model is：
Air supply pipe is connected with air inlet pipe 3 during use, foam fluid catheter is connected with the nozzle body 1, opens supply
Pipe with foam solution catheter switch after, foam solution hydraulic pressure effect under by the fluid passage from nozzle body 1 and foam solution
The connected one end of conduit is to other end flow at high speed, and now, gas is continued into described from air supply pipe by the air inlet pipe 3
Chamber, the gas in outside gas pressure lower inner cavity are constant to the port of export by arrival end of the through hole from fluid passage
Ground is just swiftly flowing foam solution inflates to form foam in fluid passage, and the foam of formation is under the effect of the pressure from shower nozzle sheet
Ejected in body, so as to complete formation of foam and the whole workflow of injection.
It was found from foregoing description, the beneficial effects of the utility model are：Nozzle structure is simple, and air can fill with foam solution
Divide mixing, foam formation efficiency is high, and the foam generated is uniform.
Further, the nozzle body 1 is cylindrical structure.
Seen from the above description, cylindrical structure has larger foam liquid import.
Further, the inner core 2 is cylindrical structure, and the bottom surface radius of the cylinder is less than the cylindrical structure
The section radius of inwall.
Seen from the above description, narrow fluid passage is formed between cylinder and cylinder inner wall.
Further, the both ends of the inner core 2 are respectively equipped with least two protuberance, and the inner core 2 passes through described convex
The inwall for going out portion with the nozzle body 1 is connected.
Seen from the above description, protuberance connects inner core 2 and nozzle body 1 as fixed pivot,
Further, the outer side wall surface of one end of the cylindrical structure is provided with external screw thread.
