Description

Technical Field

[0001] The utility model relates to the technical field of gas filtering, in particular to a gas filtering box which can reduce air inhalation resistance. Background Art

[0002] The gas filter box is an important component of a gas mask in labor protection products, used to filter poisonous gases. The gas filter box can be cylindrical or trapezoidal, made of plastic, and filled with a certain type of activated carbon agent. It is a device for removing dust, toxic and harmful gases in the air through physical adsorption and chemical reaction principles for human breathing. It is usually used in conjunction with a gas mask and is generally valid for 5 years. The surface is mostly coated with anti-alkali paint. There is a smoke filter layer inside the gas filter box to filter out smoke particles. The filter element is filter paper, glass fiber or other synthetic materials. The gas filter box can be filled with corresponding types of activated carbon according to different poisonous gases to adsorb different poisonous gases.

[0003] During use, the existing gas filter box will inhale, filter and adsorb dust and toxic gases in the air. Over time, the filter holes of the gas filter box are easily clogged with dust and need to be manually cleaned. If it is not cleaned in time, the filtering effect of the gas filter box will be reduced. At the same time, when worn for a long time, the user will experience breathing difficulties, resulting in inhalation resistance, which will cause discomfort to the user and affect its practicality. Utility Model Content

[0005] Preferably, the filter cotton cover is installed above the filter box body, and the filter cotton cover is a hollow structure.

[0006] Preferably, the fixing rod is fixedly mounted on the inner wall of the filter cotton cover, and a plurality of the fixing rods are provided.

[0007] Preferably, the electrostatic filter cotton is installed below the filter cotton cover.

[0008] Preferably, the air vent is opened at the upper end of the filter box body, the box cover is movably installed above the air vent, and the filter is installed on the inner wall of the air vent. Beneficial Effects

[0009] The gas filter box that can reduce the inhalation resistance is installed inside the gas filter box body through the electrostatic filter cotton. The electrostatic filter cotton uses the electrostatic field to capture and remove particulate matter in the air, so that the charged particles in the air are adsorbed on the charged filter net, thereby achieving effective removal of particulate matter. This electrostatic effect together with physical filtration and chemical adsorption constitutes the gas filter box body, which can filter out harmful substances in the air together to ensure that the air people inhale is clean. The filter cotton cover is installed on the upper part of the gas filter box body, which is convenient for people to open the filter cotton cover to replace the electrostatic filter cotton inside the gas filter box body, thereby ensuring the usability of the gas filter box body when in use. Energy and safety are ensured by installing it on the top of the filter box through the air vent. When the user has difficulty breathing during wearing, the user can open the box cover, and air can enter the filter box through the opening of the box cover, thereby ensuring that the user can breathe smoothly and maintain sufficient air permeability. At the same time, when the air enters the inside of the filter box, the dust and particles in the air are filtered through the filter, so that the inhaled air becomes cleaner and safer after being processed by the filter, and the resistance of the user's inhalation is reduced, thereby ensuring that it can meet the ventilation needs and effectively prevent the invasion of toxic substances and impurities.
