Technical Field
[0001] This utility model relates to the field of weld cleaning equipment, and in particular to a smoke-sucking sleeve structure applied to a weld cleaning brush. Background Technology
[0002] Chinese patent publication CN219253457U discloses a technical solution entitled "A Weld Bead Cleaning Gun with Water Pump and a Weld Bead Cleaning Machine," which includes the following technical features: a carbon fiber brush assembly, an extension rod, a cleaning gun body, a water pump assembly, and a weld bead cleaning machine. During cleaning, electrolyte is sprayed from the carbon fiber brush assembly onto the weld bead, thus cleaning it. While this achieves a relatively good cleaning effect, it generates harmful fumes. Because there is no fume collection module, the generated fumes disperse around the workpiece, easily causing environmental pollution and being inhaled by operators, potentially affecting their health. Although some solutions have incorporated suction ports into weld bead cleaning guns, these solutions suffer from problems such as unreasonable port placement, poor suction capacity, and health risks. Therefore, it is essential to design a fume extraction sleeve structure for use on a weld bead cleaning brush to address these technical issues. Utility Model Content
[0003] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide a fumigation sleeve structure for use on a weld cleaning brush. The overall structure of the fumigation sleeve structure is very simple and reliable. It can not only meet the normal weld cleaning needs, but also achieve a very comprehensive and effective fumigation effect. It can quickly and effectively remove smoke to prevent workers from inhaling it, and can better protect the health of workers.
[0004] The technical solution of this utility model is implemented as follows:
[0005] A fumigation sleeve structure for use in weld cleaning brushes is characterized by comprising an outer tube and an inner tube, wherein the inner hole of the inner tube is a liquid passage for embedding brush bristles, the inner tube is disposed in the outer tube, and a suction gap arranged around the inner tube is reserved between the outer tube and the inner tube.

[0027] like Figure 1 and Figure 2 As shown, the present invention provides a fumigation sleeve structure for use on a weld cleaning brush, comprising an outer tube 1 and an inner tube 2, wherein the inner hole of the inner tube 2 is a liquid passage hole 10 for embedding the brush bristles, the inner tube 2 is disposed in the outer tube 1, and a suction gap 20 is reserved between the outer tube 1 and the inner tube 2 and arranged around the inner tube 2.
[0028] This fumigation sleeve structure includes an outer tube 1 and an inner tube 2. The inner hole of the inner tube 2 is a liquid passage hole 10 for embedding brush bristles. The inner tube 2 is disposed inside the outer tube 1, and a suction gap 20 is reserved between the outer tube 1 and the inner tube 2, arranged around the inner tube 2. This fumigation sleeve structure not only has a very simple structure, but also forms a suction gap 20 around the opening of the liquid passage hole 10. Its overall structure is very simple and reliable. It can achieve a very comprehensive and effective fumigation effect while meeting the normal welding bead cleaning requirements. It can quickly and effectively remove smoke to prevent workers from inhaling it, and it can better protect the health of workers.
[0029] like Figure 1 and Figure 2As shown, the inhalation gap 20 can be one or more; when there is one, it is cylindrical so that it can surround the liquid passage hole 10; when there are multiple, each inhalation gap 20 surrounds the liquid passage hole 10, and the distance between adjacent inhalation gaps 20 is as small as possible (can be controlled below 2mm); in this way, the inhalation gap 20 can produce a comprehensive and effective inhalation effect.
[0030] Based on the aforementioned structure, smoking sleeve structures with the following types of outer tubes have also been designed:
[0031] The first type, such as Figure 7 As shown, at least one end face of the outer tube 1 is a concave arc-shaped end face 11. This allows the end face of the outer tube 1 to fit more closely with the position of the weld when the weld bead is on the arc-shaped convex surface, which makes the smoke extraction more stable in this environment, thus well meeting the usage requirements of this environment.
[0032] The second type, such as Figure 8 and Figure 9 As shown, at least one clearance notch 12 is provided on at least one end face of the outer tube 1. This allows the end of the outer tube 1 to fit more closely to the corner when the weld bead is at a positive angle, thus ensuring stable smoke extraction in this environment. At the same time, the clearance notch 12 can be locked onto the corner, which can play a certain limiting and guiding role, making the cleaning of the weld bead more accurate and stable, thereby well meeting the usage requirements of this environment.
[0033] The third type, such as Figure 10 As shown, at least one oblique cut surface 13 is provided on the side of at least one end face of the outer tube 1. This allows the end of the outer tube 1 to be closer to the turning point of the inside corner when the weld bead is at the inside corner, which ensures that the smoke extraction in this environment is very comprehensive and stable, thus well meeting the usage requirements of this environment.
[0034] Based on the aforementioned structure, two types of smoking sleeve structures with different inner and outer tube lengths were also designed, namely:
[0035] The first type, such as Figure 11 As shown, at least one end of the inner tube 2 protrudes beyond the corresponding port of the outer tube 1. This reduces the impact of the end of the outer tube 1 on the weld bead approaching the end of the inner tube 2 in the tank, making it easier to clean the weld bead when cleaning it in the tank, thus better meeting the usage requirements of this environment.
[0036] The second type, such as Figure 12As shown, at least one end of the inner tube 2 is located within the corresponding port of the outer tube 1. This allows the suction gap 20 to be positioned close to the small weld bead in a hood-like manner, thereby achieving a more comprehensive and effective smoke extraction effect and better meeting the usage requirements of this environment.
[0037] The application environments of the outer tube 1 are not limited to those described above; it can also be used in other environments as needed. Furthermore, during actual manufacturing, the end face of the inner tube 2 can still be made flush with the end face of the outer tube 1.
[0038] like Figure 2 As shown, the wall of the liquid passage 10 is provided with an internal thread 101, and the outer tube 1 is fixedly connected to the inner tube 2. This allows the smoke extraction sleeve structure to be threaded onto the liquid supply tube 100 using the internal thread 101. When the brush 200 is in contact with the liquid supply tube 100, rotating the outer tube 1 causes the inner tube 2 to rotate as well, thereby adjusting the exposed length of the brush 200. This not only facilitates controlling the exposed length of the brush 200 based on its wear, but also allows for adjustment of the exposed length according to different cleaning needs, thus enabling high-quality weld cleaning and further improving the reliability and applicability of the smoke extraction sleeve structure.
[0039] In actual manufacturing, the outer tube 1 can be made into a stepped tube with a larger diameter at one end and a smaller diameter at the other end (not shown in the figure), and the inner tube 2 is located in the larger end of the outer tube 1. This not only meets the normal smoke extraction requirements, but also avoids making the weld cleaning brush structure connected to the outer tube 1 too large, thereby reducing the amount of material used in the weld cleaning brush structure and thus achieving the goal of controlling manufacturing costs. This helps to further improve the applicability of the smoke extraction sleeve structure.
[0040] like Figure 2 As shown, the liquid passage 10 is a threaded hole, and the outer tube 1 is fixedly connected to the inner tube 2. Making the entire liquid passage 10 a threaded hole not only allows for a larger adjustment range but also facilitates changing the direction of use, thereby making the smoking sleeve structure more versatile.
[0041] like Figure 1 and Figure 2 As shown, at least one connecting block 3 is provided between the inner wall of the outer tube 1 and the outer wall of the inner tube 2, and the outer tube 1 and the inner tube 2 are fixedly connected together by the connecting block 3. This can stably and reliably connect the outer tube 1 and the inner tube 2 together, which not only facilitates their installation and positioning, but also makes the overall structure more stable and reliable, thereby helping to further improve the reliability and applicability of the smoking sleeve structure.
[0042] like Figure 1As shown, when two or more connecting blocks 3 are set, each connecting block 3 is arranged around the inner tube 2, which makes the connection between the inner tube 2 and the outer tube 1 more stable and reliable, thereby helping to further improve the reliability and applicability of the smoking sleeve structure.
[0043] like Figure 1 and Figure 2 As shown, the connecting block 3 is located between the inner end of the outer tube 1 and the inner end of the inner tube 2. This keeps the connecting block 3 away from the smoking end, thus preventing it from affecting the smoking process and making the smoking more comprehensive and stable. This helps to further improve the reliability and applicability of the smoking sleeve structure.
[0044] like Figure 1 and Figure 2 As shown, the axial center lines of the inner tube 2 and the outer tube 1 are coaxial; the connecting block 3 is strip-shaped, and its length direction is in the same direction as that of the inner tube 2. This not only makes the assembly of the outer tube 1 and the inner tube 2 more stable and reliable, but also ensures that its smoking is very stable, thereby further improving the reliability and applicability of the smoking sleeve structure.
[0045] The outer tube 1 and the inner tube 2 are detachably connected together. This allows for the replacement of only one of the outer tubes 1 and 2 if damage occurs, eliminating the need for a complete replacement and reducing maintenance costs.
[0046] In actual manufacturing, the outer tube 1 and inner tube 2 can be detachably connected in the following ways: First, by using at least one screw (not shown in the figure), the threaded end of which is simultaneously screwed onto both the outer tube 1 and the inner tube 2. Second, by providing a snap-fit structure (not shown in the figure) between the inner wall of the outer tube 1 and the outer wall of the inner tube 2, thus achieving a detachable connection. Third, by screwing together several threaded strips and locking them with at least one screw (not shown in the figure). Using threaded strips not only facilitates the screwing connection but also makes it easier to form the suction gap 20.
[0047] like Figures 3 to 6As shown, in actual use, this fumigation sleeve structure is used in conjunction with the following weld cleaning brush structure. The weld cleaning brush structure 1000 includes a liquid supply tube 100 and a fumigation tube 300. The liquid inlet end of the liquid supply tube 100 is placed in the fumigation tube 300, and a fumigation channel 400 is reserved between the outer wall of the liquid supply tube 100 and the inner wall of the fumigation tube 300. The brush bristles 200 are connected to the liquid outlet end of the liquid supply tube 100, allowing the liquid supply tube 100 to supply liquid to the brush bristles 200. The inner tube 2 is threaded onto the liquid outlet end of the liquid supply tube 100, and the outer tube 1 is slidably fitted or embedded in the fumigation tube 300, connecting the suction gap 20 with the fumigation channel 400, and allowing the brush bristles 200 to extend out of the inner tube 2. This satisfies normal fumigation and cleaning needs, thus meeting the requirements of actual use.
[0048] In actual use, the above-mentioned weld cleaning brush structure is applied to a weld cleaning machine to supply electrolytic cleaning fluid to the liquid supply pipe 100 and liquid passage 10. The weld cleaning machine has an air suction filter module, which is connected to the smoke extraction channel 400 to filter and collect the smoke, thereby meeting the normal weld cleaning needs.
[0049] In practical use, the two ends of the smoking sleeve structure are interchangeable, and the two ends can be made in different styles. This allows users to switch between them according to different usage environments, thus meeting various usage needs. Furthermore, if one end is damaged, it can be replaced with the good end.
[0050] like Figures 3 to 6 As shown, the bristles 200 loosely fill the liquid passage 10. The cleaning fluid discharged from the liquid passage 10 keeps the bristles 200 moist and ensures that a suitable amount of cleaning fluid is sprayed onto the weld bead. This allows the weld bead to be cleaned together by the cleaning fluid and the tip of the bristles 200. This not only meets normal cleaning needs but also prevents the suction gap 20 from directly sucking in the cleaning fluid, thus ensuring a smooth and stable weld bead cleaning process. When brushing with the tip of the bristles 200, the suction gap 20 is in a higher position, which prevents the suction gap 20 from directly sucking in the cleaning fluid, thus meeting the needs of normal smoke extraction. After the weld bead is cleaned, by lowering the suction gap 20, making it very close to or in contact with the waste liquid and residue, the need to remove the waste liquid and residue can be met. In actual use, the suction gap 20 can be omitted from removing the waste liquid and residue; the waste liquid and residue can be cleaned separately.
[0051] 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.
