Description

Technical Field

[0001] The utility model relates to a foaming and nozzle device of a foam pot. Background Art

[0002] High-pressure cleaning machines are often used for car washing. A foam pot is a component connected to the gun head of the high-pressure cleaning machine. For example, a foam pot disclosed in publication number CN 221131726 U mainly includes a foaming body with a four-way structure, a joint assembly arranged at the input end of the foaming body, a foaming and nozzle device arranged at the output end of the foaming body, a foam concentration regulating device arranged at the upper and lower ends of the foaming body, and a spray pot assembly.

[0003] In actual use, it was found that the foaming balls in the foaming and nozzle devices are easily clogged, affecting the foaming effect. To clean the foaming balls, it is necessary to first pull out the card pin and then remove the rotating sleeve. Without special tools such as a flat-blade screwdriver, it is difficult to pull out the card pin by hand, and the process of inserting and removing the card pin is also time-consuming. The product needs to be further optimized. Utility Model Content

[0004] In view of the shortcomings existing in the above problems, the utility model provides a foaming and nozzle device for a foam pot.

[0005] To achieve the above-mentioned purpose, the utility model provides a foaming and nozzle device of a foam pot, comprising a mixing tube connected to a foaming body, a rotating sleeve sleeved outside the mixing tube, and a clip assembly arranged at the free end of the rotating sleeve, wherein an air inlet hole is formed on the mixing tube, and the rotating sleeve forms a foaming cavity for installing a foaming ball at the output end of the mixing tube, and the rotating sleeve comprises three parts: a rear sleeve, an outer front sleeve, and an inner front sleeve, and a clamping pin is penetrated on the rear sleeve, and the clamping pin is simultaneously penetrated into the clamping groove of the mixing tube to form an axial limit, and the outer front sleeve is connected to the rear sleeve by a thread to form a whole, and the inner front sleeve is built in the outer front sleeve and axially limited by the outer front sleeve.

[0006] Furthermore, the mixing tube and the foaming body are screwed together via threads.

[0007] Furthermore, the front and rear ends of the mixing tube are respectively provided with a sealing ring a and a sealing ring b, wherein the sealing ring a is used for sealing between the mixing tube and the inner front sleeve, and the sealing ring b is used for sealing between the mixing tube and the rear sleeve.

[0008] Furthermore, the card pin is U-shaped and the card slot is annular.

[0009] Furthermore, a protrusion is formed on the outer wall of the inner front sleeve, and a step is formed on the inner wall of the outer front sleeve. The step and the protrusion interact to achieve axial limiting, and at the same time, the rear end of the inner front sleeve abuts against the wall surface of the slot.

[0010] Furthermore, the clip assembly includes a clip bracket, two clips, and an angle adjustment knob. The clip bracket is assembled on the inner front sleeve and forms a limit for the two clips. The angle adjustment knob can be rotatably configured on the outer front sleeve. The angle adjustment knob can adjust the opening and closing angles of the two clips by rotating.

[0011] Furthermore, the foaming body has a four-way structure, and the remaining three passages of the foaming body are respectively connected to the joint assembly, the foam concentration regulating device, and the spray pot assembly.

[0012] Compared with the prior art, the utility model has the following beneficial effects: no special tools are needed, and no plugging and unplugging of the card pin is needed. After the outer front sleeve is unscrewed, the foam ball inside the inner front sleeve can be easily taken out, and the cleaning and maintenance of the foam ball is very convenient.

DETAILED DESCRIPTION

[0019] like Figures 1 to 5As shown, a foaming and nozzle device of a foam pot in an embodiment of the utility model comprises a mixing tube 2 connected to a foaming body 1, a rotating sleeve 5 sleeved on the outside of the mixing tube 2, and a clip assembly 8 arranged at the free end of the rotating sleeve 5. An air inlet 21 is formed on the mixing tube 2, and the rotating sleeve 5 forms a foaming cavity for installing a foaming ball 7 at the output end of the mixing tube 2. The rotating sleeve 5 comprises three parts: a rear sleeve 51, an outer front sleeve 52, and an inner front sleeve 53. A card needle 4 is penetrated on the rear sleeve 51, and the card needle 4 simultaneously penetrates into the card groove 22 of the mixing tube 2 to form an axial limit. The outer front sleeve 52 is connected to the rear sleeve 51 by a thread to form a whole, and the inner front sleeve 53 is built in the outer front sleeve 52 and axially limited by the outer front sleeve 52; more specifically, the mixing tube 2 and the foaming body 1 are screwed together by a thread; the front and rear ends of the mixing tube 2 are respectively provided with sealing rings a6 and b3, and the sealing ring a6 is used for the mixing tube 2 and the inner The sealing between the front sleeve 53, the sealing ring b3 is used for sealing between the mixing tube 2 and the rear sleeve 51; the card needle 4 is U-shaped, and the card slot 22 is annular; a protrusion 531 is formed on the outer wall of the inner front sleeve 53, and a step 521 is formed on the inner wall of the outer front sleeve 52, and the step 521 and the protrusion 531 interact to achieve axial limit, and at the same time, the rear end of the inner front sleeve 53 is against the wall surface of the card slot 22; the clip assembly 8 includes a clip bracket 81, two clips 82, and an angle adjustment knob 83.
