[0002] Fume purifiers are devices that absorb fumes and purify the air. Currently, in welding work environments, fumes are generated during welding operations, so fume purifiers are needed to absorb the fumes and purify the working environment.

[0003] Existing smoke purifiers typically consist of multiple components, with the filter being a key element. Its main function is to capture suspended particulate matter, smoke, and other pollutants in the air. However, most smoke purifiers currently in use use fixed-installation filters. This design requires additional tools and consumes considerable time and effort when replacing the filter, resulting in a poor user experience. Furthermore, the design, which makes it difficult to quickly disassemble and replace the filter, may lead to users failing to replace it in time when it becomes saturated, thus reducing the purifier's efficiency. Therefore, this paper proposes a smoke purifier with a filter that is easy to disassemble and clean. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figure 1-4 The image shows an easy-to-clean smoke purifier.

[0028] Example 1: The smoke purifier includes a purification box 100, a filter element frame 201, and a limiting and blocking mechanism. The purification box 100 is equipped with a purification filter element 200 for smoke filtration. An exhaust fan 101 is fixedly installed on the bottom side wall of the purification box 100. The exhaust fan 101 is used to exhaust the gas inside the purification box 100. An air inlet channel 102 is fixedly installed on the top of the purification box 100. The air inlet channel 102 is used for directional transmission of smoke. A box cover 103 is movably sleeved on the top of the exhaust fan 101. One end of the air inlet channel 102 is fixedly connected to the box cover 103. By exhausting the gas inside the purification box 100 through the exhaust fan 101, a negative pressure suction effect is generated at the port of the air inlet channel 102. The negative pressure suction is used to draw smoke from the air inlet channel 102 into the purification box 100, and the smoke passes through the purification filter element 200 to achieve the purpose of filtration and purification, thereby achieving the purification of smoke. The air inlet channel 102 can be composed of a universal tube and a horn cover.

[0029] Furthermore, the filter element outer frame 201 is fixedly connected to the inside of the purification chamber 100, and the purification filter element 200 is movably inserted into the inner side of the filter element outer frame 201. A sealing gasket 202 is fixedly provided at the bottom of the inner side of the filter element outer frame 201. Both the filter element outer frame 201 and the sealing gasket 202 have through holes communicating with the purification filter element 200 in the middle. The limiting and blocking mechanisms are distributed in an array at the top of the filter element outer frame 201. The limiting and blocking mechanisms are rotatably connected to the top of the filter element outer frame 201, and the ends of the limiting and blocking mechanisms extend to the purification filter element 200. At the top of 0, the filter element 200 is supported by the filter element frame 201 installed inside the purification box 100. Then, the sealing gasket 202 is used to seal the port position between the sealing gasket 202 and the filter element frame 201. The limiting and blocking mechanism provides downward extrusion force to the filter element 200, which not only blocks and limits the filter element 200 in the vertical upward direction, but also creates a squeezing effect between the filter element 200, the filter element frame 201 and the sealing gasket 202, enhancing the airtightness between the three.

[0030] The limiting and blocking mechanism includes a positioning head 203 and a T-shaped connecting rod 205. The positioning head 203 is positioned above the filter element outer frame 201, with the bottom of the end of the positioning head 203 near the purification filter element 200 protruding downwards. A telescopic deep groove 204 is formed at the top of the filter element outer frame 201. The T-shaped connecting rod 205 is slidably connected to the inside of the telescopic deep groove 204. A return spring 206 is fixedly connected between the T-shaped connecting rod 205 and the telescopic deep groove 204. The top of the T-shaped connecting rod 205 is rotatably connected to the bottom of the positioning head 203. By manually pulling up the positioning head 203 and causing it to rotate and disengage from above the purification filter element 200, the obstruction to the purification filter element 200 can be released, allowing the purification filter element 200 to be directly pulled out from the filter element outer frame 201. This makes the disassembly of the purification filter element 200 more convenient. After the purification filter element 200 is installed inside the filter element outer frame 201, simply keep the positioning head 203 pulled up and rotate the positioning head 203 to move the end of the positioning head 203 above the purification filter element 200. Then release the pulling force, and use the downward pulling force provided by the return spring 206 to make the end of the positioning head 203 provide downward pressure on the top of the purification filter element 200. This can achieve the blocking and limiting of the upper position of the purification filter element 200 and provide downward pressure to the purification filter element 200, ensuring that the purification filter element 200 is installed firmly inside the filter element outer frame 201 while maintaining the airtightness of the installation. This makes the disassembly and assembly of the purification filter element 200 more convenient and efficient, and facilitates the disassembly, assembly and cleaning of the purification filter element 200.

[0031] Example 2: Based on Example 1, a locking mechanism is provided between the lid 103 and the purification chamber 100. The locking mechanism is used to lock and fix the lid 103 at the top position of the purification chamber 100. The locking mechanism includes a buckle 104, an F-shaped hook 106, and a torsion spring 107. The buckle 104 is movably fitted against the top of the side wall of the purification chamber 100, and the top of the buckle 104 is fixed to the bottom of the lid 103. The F-shaped hook 106 is rotatably connected to a... A hinge seat 105 is fixed to the side wall of the purification chamber 100. The top of an F-type hook 106 is movably inserted into the bottom of a buckle 104. Both the bottom of the buckle 104 and the top of the side wall of the F-type hook 106 are beveled. A torsion spring 107 is fixedly connected between the hinge seat 105 and the F-type hook 106, and the torsion spring 107 is used for the automatic rotation and reset of the F-type hook 106. When the chamber cover 103 is placed on the top port of the purification chamber 100, the hook... The inclined surface between buckle 104 and F-type hook 106 allows buckle 104 to move smoothly downwards, squeezing open the top of F-type hook 106. Combined with the rotational torque provided by torsion spring 107 to F-type hook 106, when the bottom arc-shaped through hole of buckle 104 moves down to the top arc-shaped protrusion of F-type hook 106, the top arc-shaped protrusion of F-type hook 106 can be inserted into the bottom arc-shaped through hole of buckle 104, thereby limiting and locking the position of buckle 104. This allows the lid 103 to be locked to the purification box 100. When disassembling, simply press the bottom of F-type hook 106 to rotate it and separate it from buckle 104 to unlock it. This makes it easier to install and remove lid 103 from the top of purification box 100. At the same time, to enhance the airtightness between lid 103 and purification box 100, a sealing gasket can be added at the connection point between the two.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
