Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of waste gas purification equipment, and in particular to a waste gas purification method applied to environmental detection. Background Art
[0002] Atmospheric pollutants are harmful to the human body in many ways, mainly manifested in respiratory diseases and physiological dysfunctions, as well as irritation of mucous membranes such as the eyes and nose. It is a chronic factor causing asthma in the elderly, and insufficient lung qi leads to a decline in physical strength. In newly renovated or polluted environments, there are many air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), so it is necessary to purify the exhaust gas in the environment. In the prior art, such as the exhaust gas purification system of patent CN2020115054052, the uniformity of liquid spraying is improved through the spray pipe to achieve the exhaust gas purification effect, so the exhaust gas purification technology is widely used.
[0003] At present, in order to prevent damage to their own health, more and more families choose to buy air purifiers. For example, in the patent of CN2023208812952, which is an air purifier with convenient filter replacement, it can be realized that when the air purification filter plate is completely wrapped, the air intake plate is opened to take out the air purification filter plate, and the vibrating dust can be effectively blocked by the protective bag, which is beneficial to protecting the respiratory health of the replacement personnel, making the replacement method of the air purification filter plate more humane and effectively realizing the purification of waste gas in the air.
[0004] However, the above-mentioned prior art only involves the structure of the air purifier itself, and the current related air purifiers generally pursue easy operation. Some air purifiers are even so simple that they only have an on / off function. Therefore, the inventors found that the defect of the current air purifier is that solid particles will continue to be deposited on the filter net during the filtering process of the air purifier, and the existing equipment does not have an automatic cleaning device. Therefore, after working for a long time, the filter net may be blocked, and the filtering effect of the equipment will be reduced or even lost.

(3) Beneficial effects
[0017] The present invention improves the existing air purifier structure. The improved air purifier is provided with a cleaning mechanism in the supporting tube. The cleaning mechanism is provided to clean the upper surface of the filter, thereby preventing solid particles from being deposited on the upper surface of the filter, thereby ensuring that the filter always has good filtering performance. Specifically, the operation of the first motor will cause the cleaning component to rotate, and the rotation of the cleaning component will scrape off the fixed particles on the upper surface of the filter, thereby preventing the fixed particles from being deposited on the upper surface of the filter.
[0018] The cleaning assembly provided in the present invention can play an anti-stuck role. Specifically, during use, some fixed particles will enter the mesh holes in the filter. In order to prevent the equipment from being stuck, the lower cleaning brush in the present invention can move up and down relative to the upper cleaning brush in the vertical direction. Specifically, when blocked by solid particles, the lower cleaning brush will move upward relative to the upper cleaning brush, thereby avoiding the equipment from getting stuck.
[0019] When the lower cleaning brush is affected by the fixed particles and moves upward relative to the upper cleaning brush, it will move the first electrode contact piece upward, and the movement of the first electrode contact piece will contact the second electrode contact piece. The contact between the second electrode contact piece and the first electrode contact piece will connect the series circuit. After the series circuit is connected, the driving cylinder will work, and the work of the driving cylinder will drive the moving plate to move up and down. The up and down movement of the moving plate will drive the impact rod assembly to move up and down. The up and down movement of the impact rod assembly will impact the filter, causing the filter to generate mechanical vibrations, and then vibrate the solid particles deposited in the mesh of the filter to the outside of the mesh, thereby preventing the device from getting stuck.
[0020] The present invention provides an impact mechanism, which impacts the filter from below, thereby knocking the solid particles in the mesh upward to the outside of the mesh. Specifically, when the impact rod assembly moves downward, under the action of magnetic attraction, the magnet block carries the impact plate to impact the filter from below, thereby further knocking the solid particles out of the mesh.
[0021] The impact rod assembly provided in the present invention can automatically separate the magnetic impact ball from the filter, thereby isolating the magnetic attraction, so that the impact plate can perform a reset movement with the impact plate through the second support assembly. Specifically, when the impact rod assembly moves downward, the magnetic impact ball will hit the upper surface of the filter. As the impact rod assembly continues to move downward, the fixed cylinder will move downward relative to the moving block. The downward movement of the moving block will resist the arc plate to rotate toward the magnetic impact ball, thereby pushing the magnetic impact ball to move upward, causing the magnetic impact ball to detach from the filter, and causing the arc plate to move to the bottom of the magnetic impact ball, thereby isolating the magnetic attraction between the magnetic impact ball and the magnet block.
