Description

Technical Field

[0001] The utility model relates to the technical field of electric welding machines, in particular to a multi-air duct dust-proof electric welding machine. Background Art

[0002] During the use of traditional electric welders, arc welding generates a large amount of dust and particulate matter. These impurities easily accumulate inside the welder, affecting its proper operation and service life. To prevent these impurities from entering the welder, the welder is typically equipped with a simple filter, such as a single-layer filter or a simple exhaust fan. This basic filtering and exhaust method is intended to reduce dust accumulation. Furthermore, some welders use direct fan cooling to continuously dissipate heat during operation, preventing premature aging or damage to the welding head due to high temperatures. However, these designs are limited to basic filtering and heat dissipation and cannot meet the demands of long-term, high-intensity welding operations.

[0003] However, traditional filtration devices and heat dissipation structures have the following shortcomings: First, a single-layer filter cannot adequately filter fine particles and dust, which causes impurities to accumulate inside the welder, reducing the cleanliness of the equipment and, in turn, affecting welding performance. Second, the traditional single-fan cooling design cannot effectively cover the entire welding head, resulting in limited cooling effect. This is especially true under high temperature and high load conditions, where the welding head may still overheat. Furthermore, traditional cooling devices lack temperature monitoring capabilities and are unable to dynamically adjust air volume based on internal temperature changes. This results in poor heat dissipation when temperatures rise, potentially causing equipment damage. Therefore, the existing technology requires more efficient filtration systems and more intelligent heat dissipation designs to ensure the cleanliness and long-term stable operation of the welder. Utility Model Content

The filter layer initially filters large dust particles, the particle filter layer absorbs harmful gases and particulates, and the fiber cotton layer further purifies the airflow, thereby ensuring the cleanliness of the air around the equipment.

[0008] In a preferred embodiment, the present invention can be further configured such that the second fan is fixed to one side of the fin assembly, with air directed by the second fan through the air guide gap, directed toward the filter layer, and then discharged through the air outlet nozzle at the bottom of the filter cartridge. By adopting this technical solution, airflow, guided by the fin assembly and the air guide gap, enters the filter layer and is discharged externally, ensuring that filtered air is effectively discharged from the equipment, further optimizing the air flow path and preventing dust accumulation within the equipment.

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0021] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0022] The following is combined with Figures 1-4 Some embodiments of the present invention provide a multi-duct dust-proof electric welding machine.

[0023] The multi-duct dustproof welding machine of the present invention includes: an arc welding head 100, a multi-duct filter group 200, a temperature-sensing patch 300 and a heat-conducting patch 400. The temperature-sensing patch 300 and the heat-conducting patch 400 are installed on the outer surface of the arc welding head 100 by gluing or fixing structures to facilitate the rapid dissipation of heat. The multi-duct filter group 200 is fixedly installed on one side of the heat-conducting patch 400. The multi-duct filter group 200 is composed of a filter box 210, a first fan 220 and a second fan 230, and the first fan 220 and the second fan 230 are respectively fixed on both sides of the filter box 210 to provide air flow from different directions. The bottom end of the filter box 210 is provided with an air outlet nozzle facing the surface of the arc welding head 100, which is used to discharge the filtered air to the surrounding environment of the arc welding head 100 to avoid dust deposition. The filter box 210 is equipped with two filter layers 211 on the inside, facing the first and second fans 220 and 230. The two filter layers 211 are arranged in a clamp-like configuration, and each is provided with a particle filter layer 212 on its inner side to further absorb particulate matter and impurities. A fiber cotton layer 213 is also installed on the bottom surfaces of the filter layers 211 and particle filter layer 212 to further enhance the filtering effect.

[0024] In a preferred embodiment, the present invention further features a thermally conductive patch 400 with multiple parallel fin groups 410 arranged on its surface. Air-guiding gaps 411 are provided between the fin groups 410 to form heat dissipation channels and enhance heat dissipation. The thermally conductive patch 400 is made of aluminum or a composite ceramic material, and a layer of thermal grease is applied between the patch and the arc welding head 100 to enhance thermal conductivity. This design ensures stable temperature during extended operation, extending the life of the device.

[0025] By adopting the above configuration, the utility model can effectively filter the dust generated during the welding process, and at the same time accelerate the air circulation through the dual-fan structure, which significantly improves the dustproof and cooling performance of the electric welding machine.

[0026] In another embodiment, the present invention further optimizes the configuration of the filter structure to improve the filtering effect and equipment durability. The multi-duct filter group 200 includes a filter box 210, a first fan 220 and a second fan 230, wherein the first fan 220 and the second fan 230 are fans on both sides, respectively, which can blow air to the surfaces of the two filter layers 211. The filter layer 211 is a metal filter, which is used to initially intercept larger particles; the particle filter layer 212 uses zeolite or molecular sieve materials, which can adsorb small particles and harmful gases; the fiber cotton layer 213 uses an activated carbon material layer to further purify the passing airflow and ensure the cleanliness of the discharged air.

[0027] Furthermore, the temperature-sensing patch 300 is internally equipped with a temperature sensor. The signal output of the temperature sensor is connected to a thermostat, which regulates the operating power of the first and second fans 220 and 230 based on the real-time temperature monitoring. When the temperature rises, the thermostat automatically increases the fan speed, increasing air flow and enhancing heat dissipation. This ensures that the internal temperature of the welder remains stable during the welding process, even if the temperature rises rapidly, preventing damage to the equipment due to overheating.

[0028] Through the above technical solution, the utility model not only realizes multi-layer filtration, but also further enhances the dust-proof and heat-dissipating effects of the welding machine through the temperature monitoring and adjustment structure, ensuring that the equipment can work stably for a long time in a high temperature and dust environment.
