Description

High-efficiency mask fan

Technical Field

The utility model relates to the technical field of mask fans, in particular to a high-efficiency mask fan.

Background

The mask is a sanitary article, is generally worn on the mouth and nose for filtering air entering the mouth and nose so as to achieve the effect of blocking harmful gas, smell, spray, virus and other substances, and is made of gauze, paper and other materials.

The mask has a certain filtering function on air entering the lung, and has a very good effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like. The mask may be classified into an air filtering type mask and an air supplying type mask.

When the mask is worn, due to the filtering performance of the mask, the breathing of people is not smooth, and more hot air remains in the mask, so that the hot air is not easy to diffuse out, the interior is stuffy and uncomfortable to wear, and in summer, the filtering performance of the mask is reduced and the mask is uncomfortable to wear due to the fact that sweat wets the mask, so that the risk of virus infection exists when people take off the mask, and the mask polluted by sweat cannot be worn again and must be discarded, so that great waste is caused;

in the mask fan in the prior art, an independent motor is integrally placed in a shell, and blades are driven by the motor to exhaust air; although this kind of technique has realized the air exchange in the gauze mask, because put independent motor whole piece into the shell, this can lead to wearing the whole weight aggravation of gauze mask and noise increase, after trading small motor, although can reduce noise increase and reduce weight, can influence the efficiency of airing exhaust of motor.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a high-efficiency mask fan; through carrying out the split with traditional motor, install motor stator in the lower cover medial surface to establish motor rotor at motor stator outside cover, and install the flabellum in the motor rotor outside, when realizing reducing motor weight, and the efficient utilizes the space, makes the flabellum can high-efficiently rotate.

The high-efficiency mask fan is realized by the following technical scheme: comprises a mask fan main body; the mask fan main body comprises an upper cover and a lower cover; the inner side surface of the lower cover is provided with a motor stator; the motor rotor is sleeved outside the motor stator; and fan blades are arranged on the outer side of the motor rotor.

As a preferred technical scheme, the upper cover and the lower cover are buckled with each other; the surface of the upper cover is provided with a through hole, and the side surface of the upper cover is provided with a groove; the through hole is opposite to the position of the motor rotor, and the groove is opposite to the position of the fan blade.

As the preferred technical scheme, a PCB mainboard and a power supply are installed in the lower cover; the outer side surface of the lower cover is provided with a key; the power supply, the motor stator, the motor rotor and the keys are all connected with the PCB mainboard.

The utility model has the beneficial effects that:

1. the traditional motor is disassembled, the motor stator is arranged on the inner side surface of the lower cover, the motor rotor is sleeved on the outer side of the motor stator, and the fan blades are arranged on the outer side of the motor rotor, so that the weight of the motor is reduced, the space is efficiently utilized, and the fan blades can efficiently rotate;

2. through being relative with through-hole and electric motor rotor position, the recess is relative with the flabellum position, realizes reducing the time of air flow through the passageway, gets rid of the air high efficiency in the gauze mask.
