Combined type air purifier and PM2.5-preventing mask

Abstract

The invention discloses a combined type air purifier and a PM2.5-preventing mask. The combined type air purifier comprises a main machine and a secondary machine, wherein the main machine and the secondary machine can be separated or combined, and are combined to form a whole and are electrically connected with each other during use; the main machine is used for generating clean air and comprises an air feeder, an air purifier filter element and a negative ion module which are arranged in a shell, as well as a clean air output interface; the secondary machine is used for supply power for the main machine and control the work of the main machine; the secondary machine comprises a power supply and a control circuit which are arranged in the shell, as well as a control button positioned on the shell; and the main machine and the secondary machine are detachably fixed on a neck ring or an arm base and are connected with the mask through a ventilating hose. The air purifier is divided into the main machine and the secondary machine which can be assembled into a whole or can be separated, clean air is generated by the main machine, the work of the main machine is controlled by the secondary machine, the combined type air purifier is convenient in structures, smaller in occupied space and convenient to maintain, and assembling can be conducted according to the actual occasion requirements, so that conditions are created for enriching the application modes and the application occasions of the air purifier.

Description

technical field [0001] The invention relates to an air purifier and a mask using the air purifier, in particular to a combined air purifier and an anti-PM2.5 mask. Background technique [0002] Mask products are divided into two classes in the market today, and the one, common type face shield, another kind is the face shield with air supply system that occurs recently. [0003] The first type of ordinary face mask, if attached figure 1 As shown, the adsorption process of external fresh air is completed through the self-inhalation of the human nostrils, and negative pressure is generated when the human inhales, and the negative pressure is generated by the bonding of the human face 200 and the mask 202 to form a closed space. The polluted air from the outside becomes clean air after being filtered by the mask 202, and enters the nostrils of the person. [0004] From the above principles, it can be seen that this type of technology is not prone to two problems: [0005] 1....

AI Technical Summary

Problems solved by technology

[0005] 1. Because it depends on the negative pressure controlled by people to work normally, it will lead to poor breathing, thus feeling suffocated and hypoxic

[0006] 2. The closed space necessary to form a negative pressure is completed by the face and the mask, and it is difficult to ensure that the seal is intact. That is to say, when the air intake through the mask is insufficient, the dirty air from the outside will naturally pass through the face and the mask The slit 201 enters, in this way, it cannot be guaranteed that the inhaled nostrils must be clean air

[0009] 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 active air blowers, although they can actively blow air, It is convenient for the user to inhale, but due to the power to drive the air, the rate of air passing through the mask is relatively increased, which also leads to a further reduction in the filter efficiency of the mask for PM2.5, so the purpose of using the mask cannot be achieved

[0010] Moreover, the above-mentioned masks are also subject to certain restrictions in practical application. For example, when users drive a car, communicate with people face-to-face, hold meetings, communicate, or exercise in large office spaces without air purifiers, wearing a mask is a problem. Out of season, so the user cannot breathe relatively clean air in these situations
