[0023] like Figure 1 and Figure 2 As shown, the adapter used in the weld cleaning gun of this utility model includes an inner connecting pipe 1 and an outer connecting pipe 2 that can be detachably connected to the brush head. The inner connecting pipe 1 and the outer connecting pipe 2 are connected and communicate with each other.

[0024] In this adapter, the inner connecting pipe 1 can be used to connect to the liquid supply pipe, and the outer connecting pipe 2 can be connected to the brush head with a detachable clamp. This allows for easy installation and removal of the brush head by simply plugging and unplugging it, eliminating the need for cumbersome rotation operations. This facilitates quick and easy installation and removal of the brush head, saving time and effort and effectively reducing inconvenience to production. It is highly versatile. Furthermore, the overall structure of this adapter is very simple and reliable.

[0025] The outer connecting pipe 2 can be detachably connected to the brush head via a retaining sleeve. This means either the brush head can be detachably connected to the outer connecting pipe 2, or the outer connecting pipe 2 can be detachably connected to the brush head. Both of these configurations fall within the protection scope of this utility model.

[0026] like Figure 1 As shown, the outer circumferential surface of the outer connecting pipe 2 is non-circular. This prevents the brush head from rotating relative to the outer connecting pipe 2 when the brush head is assembled, thus making the installation of the brush head more stable and reliable; and when a flat brush head is used, this helps to accurately position the flat brush in the appropriate operating state; thereby further improving the reliability and applicability of the adapter.

[0027] like Figure 1 and Figure 2 As shown, a positioning ring groove 21 is formed on the outer circumferential surface of the outer connecting pipe 2, and a positioning spring 22 is fitted into the positioning ring groove 21. When the positioning spring 22 is not compressed, its outer wall protrudes outside the positioning ring groove 21; when the positioning spring 22 is compressed, it retracts towards the bottom of the positioning ring groove 21. This not only facilitates the mounting and dismounting of the brush head, but also helps to achieve a stable and reliable positioning of the brush head, thereby further improving the reliability and applicability of the adapter.

[0028] The outer connecting pipe 2 and the inner connecting pipe 1 are connected at one end by a circular tube, while the outer circumferential surface of the other end of the outer connecting pipe 2 is a non-circular surface. The positioning annular groove 21 is formed on the circular tube. This not only facilitates the creation of the positioning annular groove 21 but also helps to achieve stable assembly.

[0029] like Figure 1 and Figure 2 As shown, the inner bore of the inner connector 1 is a fitting hole 11 for fitting the liquid supply tube, and the outer connector 2 and / or the inner connector 1 are provided with at least one threaded hole 12 extending therethrough. The threaded hole 12 can be used for installation with a set screw, which can be locked by the set screw when fitting the fitting hole 11, which helps to further improve the stability and reliability of the adapter installation and positioning.

[0030] like Figure 2 As shown, the threaded hole 12 can be opened between the outer connecting pipe 2 and the inner connecting pipe 1, and the opening of the fitting hole 11 is a flared opening, which facilitates quick and accurate fitting, thereby helping to further improve the convenience of installation and positioning of the adapter.

[0031] like Figure 2 As shown, the fitting hole 11 is a threaded hole. This facilitates stable and reliable installation of the adapter on the liquid supply pipe, thereby further improving the reliability and applicability of the adapter. The adapter is not a consumable and does not require frequent disassembly and assembly. The threaded hole not only does not affect production but also ensures that the adapter's installation and positioning are highly stable and reliable.

[0032] like Figure 7 As shown, in the actual manufacturing process, external threads 14 can also be opened on the outer circumferential surface of the inner connecting pipe 1 to achieve threaded connection of the liquid supply pipe, which can also meet the needs of actual use very well.

[0033] like Figure 1 and Figure 2 As shown, the inner connecting pipe 1 and / or the outer connecting pipe 2 are provided with a protruding ring portion 13. The protruding ring portion 13 not only accommodates the smoking tube 10 but also prevents interference between the smoking tube 10 and the brush head, thus effectively meeting the needs of smoking. When the smoking tube 10 is fitted onto the protruding ring portion 13, the brush head is also positioned within its inner hole, further enhancing the smoking experience.

[0034] like Figures 3 to 5 As shown, the smoking tube 10 includes an inner tube and an outer tube. The inner tube is arranged inside the outer tube. A smoking gap is reserved between the outer circumferential surface of the inner tube and the inner circumferential surface of the outer tube. The inner tube and the outer tube are fixedly connected together by a connecting piece arranged between them, so as to meet the normal smoking needs.

[0035] like Figures 1 to 5As shown, an external thread 131 is provided on the outer circumferential surface of the convex ring portion 13. This not only enables stable installation of the smoke tube 10, but also meets the needs of adjusting the smoke tube 10. This allows the amount of the brush head exposed to be adjusted by rotating the smoke tube 10, so that the appropriate amount of the brush head can be exposed according to different usage requirements or the wear of the brush head, thereby better meeting the needs of actual use.

[0036] An external thread 131 is provided on the convex ring 13 for the smoke extraction tube 10 to be screwed on, which can prevent the cleaning fluid from flowing back during liquid supply, thereby making the working performance of the weld cleaning gun more stable and reliable.

[0037] like Figures 3 to 6 As shown, the adapter used in the weld cleaning gun also includes a liquid supply pipe 3 and a brush head 4. The brush head 4 includes a sleeve tube 41 and bristles 42. The bristles 42 are embedded in one end of the sleeve tube 41, and the other end of the sleeve tube 41 is detachably connected to the outer connecting pipe 2. The inner connecting pipe 1 is connected to the liquid supply pipe 3. This allows the liquid supply pipe 3 and the brush head 4 to connect well, thus meeting the needs of practical use very well.

[0038] like Figures 3 to 5 As shown, the liquid supply pipe 3 and the smoke extraction pipe 10 are both accessories on the weld cleaning gun, and the weld cleaning gun assembled in this way can meet the needs of actual use.

[0039] like Figure 1 and Figure 2 As shown, the sleeve tube 41 is a copper tube, the liquid supply tube 3 is a brass tube, a copper tube, or a stainless steel tube, and the outer connecting tube 2 and the inner connecting tube 1 are integral stainless steel tubes. This not only perfectly meets the requirements of conductivity, liquid cooling, and electrolytic cleaning, but also facilitates the processing of the sleeve tube 41. Furthermore, the stainless steel outer connecting tube 2 and inner connecting tube 1 prevent direct contact between the copper tube sleeve tube 41 and the liquid supply tube 3, thus avoiding corrosion between the copper tubes and the resulting inability to disassemble. This facilitates subsequent disassembly and maintenance, further improving the applicability of the adapter.

[0040] The inner wall of the other end of the sleeve tube 41 is provided with a snap-fit ​​ring groove (not shown in the figure). The snap-fit ​​ring groove is snapped onto the positioning spring 22. This not only meets the stable installation requirements of the brush head 4, but also facilitates the disassembly and assembly of the brush head 4, thus perfectly meeting the needs of actual use.

[0041] like Figure 6As shown, a clamping piece 411 is recessed at one end of the sleeve tube 41. A liquid outlet hole 412, penetrating into the sleeve tube 41, is formed on the side wall of the clamping piece 411. The ends of the brush bristles 42 are held between the clamping piece 411 and the inner wall of the sleeve tube 41. This not only facilitates stable positioning of the brush bristles 42 but also allows for sufficient and accurate liquid supply to the brush bristles 42 via the liquid outlet hole 412, thereby further improving the reliability and applicability of the adapter.

[0042] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
