Description

Air guide device of portable air purifier

This creation is about a kind of air guide device, especially a kind of portable air that is used to connect to a portable air purifier, and then guide the filtered air to the user's mouth and nose, which can form an air curtain (air curtain) in front of the mouth and nose. Air guide device of cleaner.

Today, air pollution has many potential health effects, ranging from subtle physical changes in the body to obvious symptoms such as itchy nose and throat, wheezing, coughing, chest pain or chest tightness. Patients with asthma or chronic respiratory diseases will get worse if they are exposed to air pollutants. Furthermore, many infectious diseases (such as influenza, SARS, MERS, new coronary pneumonia, etc.) are infected by droplet infection, contact infection and aerosol infection. Droplet infection refers to the droplets of patients who sneezed, coughed, talked, and exhaled. Infection caused by direct inhalation of gas; contact infection refers to the infection caused by contact with the surface of the object, and then contact with mucous membranes such as the mouth, nose or eyes; as for aerosol infection, it refers to the droplets mixed in the air to form floating Aerosols, infections caused by inhalation, have a great chance of distributing infectious viruses in the air where there are many people; therefore, during the epidemic period, ordinary people need to implement basic epidemic prevention behaviors such as wearing medical-grade masks and washing hands frequently. To avoid the aforementioned virus infection. However, the general public cannot correctly distinguish and confirm the timing of wearing and replacing masks, so the protective effect of masks is often affected. In addition, when wearing a mask for a long time, it may become stuffy due to lack of ventilation and cause other skin diseases.

To this end, the creator of this case previously proposed a portable air purifying invisible protective device, which is used to form an invisible air curtain (air curtain) in front of the nose and mouth that blocks the passage of bacteria and viruses, and provides the user with filtered air. This creation is based on the further improvement of the above-mentioned invisible protective device for purifying air on the body, so that the air duct of the air guiding device can be bent and shaped arbitrarily, and the air guiding cover can close the user's chin to prevent dirty air from entering.

The purpose of this creation is to provide an air guide device for a portable air purifier. The air guide device can be connected to the portable air purifier through the structure of the nozzle bundle of the air guide device, the air guide cover and the air duct. Through the combination of the air guide tube and the shaping strip, the air guide tube of the air guide device can be bent and shaped arbitrarily, and the air guide cover can tightly fit the user's chin to prevent dirty air from entering.

In order to achieve the above-mentioned purpose, the air guide device of the portable air purifier of this invention is used to connect to a portable air purifier to guide the filtered air to the mouth and nose of the user. The preferred technical solution includes: a nozzle , Which is used to plug or sleeve the portable air purifier; an air guide cover, which has an air guide sheet for covering the front of the user's nose and mouth, the inner side of the air guide sheet has an outlet facing An air supply hole on the upper side; an air duct, which is a tube body made of bendable flexible plastic, one end of which is connected to the receiving tube bundle port, and the other end is connected to the inlet of the air supply hole; and a molding strip, which is capable of A long strip that is bent and deformed by an external force is combined with the air guide tube and extends to both ends along the air guide tube to shape the air guide tube after being bent together with the air guide tube.

In this way, the air guide device of the portable air purifier of this creation can be inserted into or sleeved on the outlet pipe of the portable air purifier through the nozzle beam, allowing the user to wear the portable air purifier on his chest, and then Adjust and shape the extended shape of the air duct and the shaping strip, so that the air guide shield covers the front of the user’s nose and mouth, and supports the user’s chin to prevent dirty air from entering through the chin. When the portable air cleaner operates At this time, the filtered air can be sprayed to the air guide plate through the air supply hole through the air guide tube, thereby forming an invisible air curtain (air curtain) in front of the mouth and nose, thereby achieving the effect of convenient adjustment and shaping.
