Abstract

The invention relates to the technical field of mask detection device, and provides a mask detection device using a piezoelectric material. The mask detection device comprises a detection device, wherein the center of the detection device is fixedly connected with a fixed bracket, and the left side and the right side of the detection device are movably connected with a bevel gear linkage structurethrough the fixed bracket. According to the mask detection device using the piezoelectric material, synthetic blood is sprayed out through a liquid spraying device, a nozzle which is arranged at theupper part of the liquid spraying device and pushes the synthetic blood to be directionally emitted guides airflow to drive the bevel gear linkage structure to rotate, fan blades are driven to rotatethrough the meshing between gears, the airflow blown by the fan blades is blown to the surface of one side of a mask mounting plate, meanwhile, the synthetic blood is more left on the inner side of the detection device, the synthetic blood presses a liquid suction drive, the liquid suction drive presses a switch for opening a liquid suction device, so that the liquid suction device absorbs liquidon the inner side of the detection device, and the detection result is guaranteed; and if a product is unqualified, wind presses a wind pressure measuring device, and the wind pressure measuring device presses a switch connected with a sound box.

Description

technical field [0001] The invention relates to the technical field of mask detection equipment, in particular to a mask detection device using piezoelectric materials. Background technique [0002] Medical masks are a kind of medical protective textiles. It belongs to labor protection products. It is made of one or more layers of non-woven fabrics. Medical masks have the functions of resisting liquids, filtering particles and bacteria, etc., because medical staff will use them. In the face of many patients, it is particularly important for the detection of blood penetration performance and airflow permeability. [0003] The commonly used test instruments for blood penetration and airflow permeability of medical masks in the market are synthetic blood penetration tester for medical masks and textile airflow resistance tester. The exchange of the two instruments increases the cost of testing, and the commonly used The blood penetration tester for medical masks sprays a certa...
