Automobile air conditioner filter capable of automatically detecting filtering effect and detection method thereof

Abstract

The invention discloses an automobile air conditioner filter capable of automatically detecting the filtering effect, which comprises a bottom frame and a working plate, the working plate is fixedly arranged at the top of the bottom frame, one end of the top of the working plate is fixedly connected with a first supporting column, and a third piston rod in the working plate is controlled by a third hydraulic cylinder to move towards the outer side of a cylinder body; the third piston rod pushes the balance plate to move, a second limiting rod is arranged on the balance plate located on one side of the third piston rod, one end of the second limiting rod penetrates through the third supporting column, the second limiting rod is parallel to the third piston rod, and when the third piston rod pushes the balance plate to move, the moving state of the balance plate is limited through the second limiting rod. The balance plate is prevented from deviating to influence the normal work of the gas detector and the section flatness detection rod, the interface flatness of the gas outlet is detected through the section flatness detection rod, the pipeline butt joint sealing performance is ensured, the gas discharged from the gas outlet is detected through the gas detector, and the gas filtering effect is judged.

Description

technical field [0001] The invention relates to the field of automotive air conditioning filter equipment, in particular to an automotive air conditioning filter capable of automatically detecting the filtering effect and a detection method thereof. Background technique [0002] The car cabin filter is a filter specially used for air purification in the car cabin. Activated carbon composite filter cloth is made of high-efficiency adsorption material-activated carbon and filament non-woven fabric; it has a compact structure and can effectively filter smoke, pollen, dust, harmful gases and various odors. The filter can also efficiently filter and adsorb particulate impurities to achieve oil filtration and air purification performance, and at the same time, it can also remove TVOC, benzene, phenol, ammonia, formaldehyde, xylene, styrene and other organic gases. It is an ideal material for automotive air conditioning filters in automobiles, sedans, and commercial vehicles. [...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of auto air conditioner filter and its detection method that can automatically detect the filtering effect, to solve the problem that the existing auto air conditioner filter cannot provide additional support for the filter housing on the base, resulting in The stability of the filter housing is poor, which affects the accuracy of the detection data; the existing automotive air conditioning filter cannot judge the installation of the filter housing through the detected height difference, and check whether the components are installed in place. It can limit the moving direction of the lifting plate, but it cannot ensure that the lifting plate will not deflect, and the accurate detection of the detection head cannot be realized; the existing automotive air conditioning filter cannot limit the moving state of the balance plate through the second limit rod, and the balance The plate is prone to offset, which will easily affect the normal operation of the gas detector and the kerf leveling detection rod. It is impossible to detect the interface flatness of the gas outlet through the kerf leveling detection rod to ensure the tightness of the pipe butt joint. There is no gas detector. It is impossible to detect the gas discharged from the gas outlet to judge whether the gas meets the emission standard
