Abstract
The invention discloses protective nasal filter equipment. The protective nasal filter equipment comprises a first plug rod and a second plug rod, wherein the second plug rod is mounted on one side of the first plug rod; and filter protection assemblies are mounted at the bottoms of the first plug rod and the second plug rod. According to the protective nasal filter equipment, an upper filter screen, a threaded connecting ring, a filter cartridge, a protective screen plate, a baffle ring, a lower filter screen, a connecting shaft and a fixed soft cushion are arranged, a rotating disc is screwed outside an external threaded ring, and the first plug rod is plugged in a nostril, so that external air enters the filter cartridge through the protective screen plate, and then is adsorbed and blocked by activated carbon in the filter cartridge, pollutants and droplets in the air are absorbed and blocked, and the protection effect can be achieved effectively; and the protective nasal filter equipment is arranged in nostrils, is not easy to see, is good in concealment, is convenient to use in public places, replaces a mask, plays a role in filtering air sucked into the nose, can also prevent haze, pollen, catkin, dust and viruses from entering respiratory tracts, and can eliminate the psychological barrier caused by wearing the mask at the same time.
Description
technical field [0001] The invention relates to the technical field of nasal protection, in particular to a protective nasal filter device.
