Description

Combined air purifier and PM 2.5-proof mask

Technical Field

The invention relates to an air purifier and a mask using the same, in particular to a combined type air purifier and a mask for preventing PM 2.5.

Background

Mask products on the market today fall into two categories, one being the ordinary type of mask, the other being the more recent mask with an air supply system.

The first type of common mask, as shown in fig. 1, completes the adsorption process of fresh air outside by the autonomous inhalation of the nostrils of the person, and generates negative pressure when the person inhales, and the negative pressure is generated by the joint of theface 200 and themask 202 to form a closed space. The outside polluted air is filtered by themask 202 and then becomes clean air to enter the nose.

As can be seen from the above principles, such techniques are prone to two problems:

1. because the negative pressure is controlled by people to work normally, the breathing is not smooth, and people feel stuffy and anoxic.

2. The necessary closed space for forming negative pressure is completed by the face and the face mask, and it is difficult to ensure the sealing is perfect, that is, when the air input through the face mask is insufficient, the external dirty air will naturally enter through thegap 201 between the face and the face mask, so that the air sucked into the nostrils cannot be ensured to be clean air.

In order to solve the above problem, a positive pressure system is also adopted: namely, the fan is used for actively supplying air, so that the two defects of the mask in the first scheme are avoided.

The specific structure and the principle of the face mask in the scheme are shown in the attached figure 2, an activeair supply fan 201 is additionally arranged on the basis of a common face mask, dirty air is sucked through thefan 201, and is filtered by theface mask 200 to become clean air and enter nostrils.

Obviously, the second type of products are more popular with consumers, but these types of masks cannot effectively prevent users from inhaling PM2.5 particles, and because the second type of masks have fans for actively blowing air, although they can actively blow air and facilitate users to inhale air, because of the power driving air, the speed of air passing through the masks is relatively increased, which also causes the filtering efficiency of the masks on PM2.5 to be further reduced, and thus the purpose of using the masks cannot be achieved.

The mask is limited in practical use, and it is not appropriate for a user to wear the mask when driving a car, communicating with a person, meeting, communicating in a large office space where an air cleaner is not installed, or exercising, for example, so that the user cannot breathe relatively clean air in such cases.
