This will not only affect the filtering effect, but may also damage other parts of the filter assembly and shorten the life of the equipment. By cleaning the filter in real time through the cleaning assembly, the particles in the harmful gas can be prevented from clogging the filter due to the suction of the fan, which can keep it in good working condition and extend the life of the equipment.

[0036] 2. Improve energy efficiency: A clogged filter may cause the harmful gas absorber to work less efficiently because more energy is required to push air through the clogged filter. Cleaning the filter can ensure that air can pass through the filter smoothly, reduce energy consumption, and improve the energy efficiency of the equipment.

[0037] 3. Reduce the intake of harmful substances: welding fumes contain a variety of harmful substances, such as heavy metals, volatile organic compounds, particulate matter, etc. These substances are harmful to human health, and long-term inhalation may cause respiratory diseases, lung diseases and even cancer. The smokeless soldering device significantly reduces the inhalation of harmful substances and reduces the harm to the human body by absorbing and filtering these fumes. At the same time, the device detects the gas in the gas outlet hopper. If the test fails, the top cover of the gas outlet hopper will be closed until the test passes, reducing the harm to the human body caused by incomplete treatment.

[0038] 4. Improve the working environment: welding smoke is not only harmful to health, but also pollutes the working environment, affecting work quality and efficiency. The application of smokeless soldering equipment can effectively improve the working environment, reduce the interference of smoke on workers and equipment, and improve work comfort and efficiency.

The top of the filter box 31 is provided with an air outlet hopper 34, and the bottom of the air outlet hopper 34 is provided with a support frame 35. The fan 36, the rotating shaft 37, and the fan blade 38 are installed to suck harmful gases into the filter box 31.
