The beneficial effects of the utility model are:Nozzle structure is simple, and air can be sufficiently mixed with foam solution, foam generation Efficiency high, the foam generated are uniform.
Further, the nozzle body is cylindrical structure.
Further, the inner core is cylindrical structure, and the bottom surface radius of the cylinder is less than the cylindrical structure The section radius of inwall.
Further, the both ends of the inner core are respectively equipped with least two protuberance, and the inner core passes through the protrusion Portion is connected with the inwall of the nozzle body.
Further, the outer side wall surface of one end of the cylindrical structure is provided with external screw thread.
Brief description of the drawings
Fig. 1 is the structural representation of foam nozzle of the present utility model;
Fig. 2 is the longitudinal cross-section structural representation of foam nozzle of the present utility model.
Label declaration:
1st, nozzle body;2nd, inner core;3rd, air inlet pipe.
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.
Seen from the above description, the external screw thread is connected with the screw-internal thread fit of foam catheter.
Figure is refer to, embodiment one of the present utility model is:
A kind of foam nozzle, include the inner core 2 and air inlet pipe 3 of cylindrical shape nozzle body 1, cylinder, the cylindrical shape spray Head main body 1 is the hollow structure that both ends have opening, and inner chamber is provided between the outer wall and inwall of the cylindrical shape nozzle body 1, The outer wall of the cylindrical shape nozzle body 1 is provided with the air inlet pipe 3, and the inwall of the cylindrical shape nozzle body 1, which is provided with, to be led to Hole, the inner core 2 of cylinder are arranged at the hollow structure of the cylindrical shape nozzle body 1, the inner core 2 of cylinder and institute State cylindrical shape nozzle body 1 to be connected, there is sky between the inwall of the inner core 2 of cylinder and the cylindrical shape nozzle body 1 Gap, the space form fluid passage, and the fluid passage extends respectively to the both ends open of the cylindrical shape nozzle body 1, The outer side wall surface of one end of the cylindrical structure is provided with external screw thread.
