Technical Field

The utility model belongs to the technical field of personal protection products, and relates to an air purifying device, in particular to a portable personal air anion purifier.

Background

The negative ion has air purifying and health protecting effects. Regarding the air purifying effect: the Chinese air negative ion and ozone research expert group writes the air negative ion in medical care and environmental protection application for many times, and has hundred percent sedimentation removal effect on PM2.5 which is difficult to remove in industry, especially on particle fly ash as small as 0.01 micron, and the negative ion with small particle size. Effects on healthcare: in the book of the application of air anions in medical care and environmental protection, a great deal of description is made on the function of the anions in human recuperation health care, and a plurality of clinical tests and research documents of the air anions for treating a plurality of diseases such as asthma, insomnia, hypertension, hyperlipidemia, malignant tumor and the like are recorded; in addition, in the "physical therapy book" written by experts and professor Qiao Zhi in national physical therapy, there is also related introduction of negative ion therapy for the adjuvant treatment of various clinical diseases, and the diseases are related to nervous system, cardiovascular system, respiratory system, etc. with obvious effects.

Therefore, the negative ions are widely applied to the fields of air purification and medical care at present, such as negative ion air purifiers, negative ion electronic masks, personal portable negative ion purifiers and the like on the market. However, at present, a class of negative ion products taking characteristics of portability, outdoor use, mouth and nose covering and the like as design concepts have certain defects during use, and are specifically expressed as follows:

1. wearing comfort is poor. The defects are mainly expressed in products such as negative ion electronic masks, and the products directly configure parts such as a negative ion generator, a battery and the like on the mask, so that the mask is complex in structure and heavy in weight, and is easy to generate strong pressing feeling on the face of a user after being worn, so that wearing comfort is poor;

2. poor air flow and poor breathing of the user. The defects are mainly manifested in products with the function of covering the mouth and the nose, the products use a mask or a face mask to directly send purified fresh air to the mouth and the nose of a user, but the products mainly adopt a structure of passive air intake, exhaust or unidirectional air supply, when the products are used, the air circulation in the mask is poor, the waste gas exhaled by the user can not be discharged in time, and a large amount of water vapor is condensed in the mask. After wearing for a period of time, the air in the mask becomes damp and hot, so that the user breathes unsmoothly and the comfort level is poor.

For example, the chinese patent application with publication number CN106377852a discloses a portable air purifying device, an air supply mask, a mask and a helmet, comprising a fresh air unit and an air supply mask which are connected by a hose, wherein the air supply mask is provided with an air supply check valve and an air exhaust check valve, and in the use state, the air supply check valve is opened during the inhalation process of breathing and closed during the exhalation process; the exhaust check valve is opened during exhalation of the breath and closed during inhalation. The breathing device only depends on the passive air inlet and air outlet of the breathing of a user, and in actual use, the breathing device can outwards exhaust air only when the air pressure in the mask is higher, and can inwards inlet air when the air pressure is lower, so that the condition that the waste gas exhaled by the user stays in the mask can occur, and further the discomfort of oxygen deficiency and suffocating is caused when the user wears the breathing device.
