Hollow structure, is provided with inner chamber between the outer wall and inwall of the nozzle body, the outer wall of the nozzle body is provided with the air inlet
Pipe, the inwall of the nozzle body is provided with through hole, and the inner core is arranged in the hollow structure of the nozzle body, described interior
Core is connected with the nozzle body, has space between the inwall of the inner core and the nozzle body, and the space forms stream
Body passage, the fluid passage extends respectively to the opening at the two ends of the nozzle body.
The beneficial effects of the present invention are：Nozzle structure is simple, and air can be sufficiently mixed with foam solution, foam formation efficiency
Height, the foam generated is uniform.
Brief description of the drawings
Fig. 1 is the structural representation of the foam nozzle of the present invention；
Fig. 2 is the longitudinal cross-section structural representation of the foam nozzle of the present invention.
Label declaration：
1st, nozzle body；2nd, inner core；3rd, air inlet pipe.
Embodiment
To describe technology contents, the objects and the effects of the present invention in detail, below in conjunction with embodiment and coordinate attached
Figure is explained.
The design of most critical of the present invention is：Cause foam solution with air narrow by continuing aerating to shower nozzle inside
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 two 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.
The present invention working mechanism be：
Air supply pipe is connected with air inlet pipe 3 when using, foam fluid catheter is connected with the nozzle body 1, supply is opened
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, arrival end of the gas by the through hole from fluid passage in outside gas pressure lower inner cavity is constant to the port of export
Ground is just inflates to form foam in the swiftly flowing foam solution 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 present invention are：Nozzle structure is simple, and air can be mixed fully with foam solution
Close, foam formation efficiency is high, 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 two 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, embodiments of the invention one are：
A kind of foam nozzle, includes 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 two 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 is provided with logical
Hole, the inner core 2 of cylinder is 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 forms 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.
Air supply pipe is connected with air inlet pipe 3 when using, the screw thread between the nozzle body 1 and foam fluid catheter is screwed,
Open after air supply pipe and foam solution catheter switch, foam solution is under hydraulic pressure effect by the fluid passage from nozzle body 1
The one end being connected with foam fluid catheter is to other end flow at high speed, and now, gas is persistently entered from air supply pipe by the air inlet pipe 3
Enter the inner chamber, the gas in outside gas pressure lower inner cavity by the intensive through hole from the arrival end of fluid passage to
The port of export is continuously for just in the fully aerated formation foam of the swiftly flowing foam solution in fluid passage, the foam of formation is in pressure
Ejected in the presence of power from head body, so as to complete formation of foam and the whole workflow of injection.
