[0039] The female connector 20 includes an outer female tube 21, an inner female tube 22, and a female body 23. The female body 23 is movably disposed inside the inner female tube 22, and the gap between the outer female tube 21 and the inner female tube 22 forms a flow cavity. The inner wall of the outer female tube 21 is provided with an annular groove 21d and a plurality of connecting holes 21e. The connecting holes 21e are arranged parallel to the circumference of the outer female tube 21, and their two ends are respectively connected to the annular groove 21d and the flow cavity.

[0040] When the quick connector is in the locked state, the front end of the male sleeve 12 extends into the female outer tube 21, the plurality of flow holes 12b are aligned with the annular groove 21d, and communicate with the flow cavity through the connection hole 21e.

[0041] Specifically, the male sleeve 12 is sealed at the front end and the male inner tube 14 is slidably installed at the rear end. The male sleeve 12 extends through the front and rear and communicates with the connecting hole 21e. The male inner tube 14 has a guide part 14a. The reciprocating movement of the male inner tube 14 relative to the male sleeve 12 causes the guide part 14a to guide the steel ball 13 to move outward or inward.

[0042] Furthermore, in combinationFigures 1-3 As shown in the embodiment, the quick connector is used as follows:

[0043] Firstly, the front end of the male connector 10 is aligned with the front end of the female connector 20, and the front end of the male outer tube 11 is tightly abutted with the front end of the female outer tube 21. Then the male sleeve 12 is pushed to move forward and push the female body 23 to move continuously until the female body 23 moves to one end of the retraction stroke. At this time, the steel ball 13 is aligned with the locking groove 21c on the inner wall of the female outer tube 21 at the position of the male sleeve 12, and the through hole 12b on the female sleeve is aligned with the annular groove 21d. Finally, the male inner tube 14 moves forward, and the guide part 14a on the male inner tube 14 pushes the steel ball 13 to move outward, so that the steel ball 13 is clamped into the annular groove 21d to realize the locking of the quick connector.

[0044] Further, in the embodiment, the rear end of the male inner tube 14 is used to connect the source of foaming liquid. The front and rear ends of the female outer tube 21 are respectively provided with a first opening 21a and a second opening 21b, and the second opening 21b is used to connect the output end and is used to output the foaming liquid and the foam generated by foaming to the outside. The female body 23 is in sliding fit with the first opening 21a. The inner wall of the female outer tube 21 is provided with two second sealing rings 24, and the front first sealing ring 17 is used for sealing between the female body 23 and the female outer tube 21. The rear first sealing ring 17 is used for sealing between the female body 23 and the female inner tube 22.

[0045] Specifically, in combination with Figures 4-5 As shown, the male sleeve 12 is circumferentially provided with a plurality of tapered holes 12a, and the steel ball 13 is arranged in the tapered hole 12a. When the steel ball 13 moves outward, a part of the steel ball 13 protrudes from the outer circumferential surface of the male sleeve 12, so as to form a close fit with the inner wall of the female outer tube 21, thereby realizing the locking function. The second elastic member 16 is arranged between the male sleeve 12 and the male inner tube 14, and the second elastic member 16 has an elastic tendency to move the male inner tube 14 away from the male sleeve 12. The first elastic member 15 is arranged between the male outer tube 11 and the male sleeve 12, and the first elastic member 15 has an elastic tendency to limit the male sleeve 12 from extending into the female outer tube 21.

[0046] Further, in the embodiment, the first elastic member 15 is sleeved on the female sleeve, and the first elastic member 15 is a spiral spring, the front end of which abuts against the female outer tube 21, and the rear end of which abuts against the outer step on the female sleeve. The second elastic member 16 is sleeved on the female inner tube 22, and the second elastic member 16 is a spiral spring, the front end of which abuts against the rear end of the female sleeve, and the rear end of which abuts against the outer step on the upper end of the female inner tube 22.

[0047] Specifically, in combination with Figure 3As shown, the outer diameter of the front end of the male head sleeve 12 is equivalent to the outer diameter of the female head body 23; when the quick connector is in the locked state, the female head body 23 seals the female head inner tube 22.

[0048] Further, in the embodiment, the front end of the female head body 23 is a cylindrical sealing part 23a, and the rear end is a connecting part 23b, the connecting part 23b abuts against the front end of the third elastic member 25, and the rear end of the third elastic member 25 abuts against the rear side wall inside the female head inner tube 22. The front end of the female head inner tube 22 has an opening, and the rear end is closed. The rear movement of the female head body 23 can seal the opening at the front end of the female head inner tube 22.

[0049] Specifically, in combination with Figures 6-7 As shown, the outer diameter of at least one section of the flow cavity gradually decreases from the front end to the rear end of the female head outer tube 21, which helps to form a flow rate gradient during the material flow process, further enhances the mixing effect, and makes the foaming process more uniform and controllable.
