Description

A kind of dust-proof mask with intelligent breathing ring

technical field

The invention relates to a dustproof mask, in particular to a dustproof mask with an intelligent breathing ring.

Background technique

At present, for dust masks, filtration efficiency or breathing resistance often cannot be taken into account. Masks that emphasize filtration efficiency, especially those that protect against fine particle pollution such as pm2.5, are often achieved by increasing the number of layers of filter material and the compactness of the filter material, which increases the breathing resistance and makes the wearer feel oppressed. Increase the physiological load of the wearer, especially for those who need to wear masks for a long time, it has caused certain health damage; masks that emphasize reducing breathing resistance often increase the air permeability of the filter material, but cannot achieve the effect of filtering and dust removal. In particular, it cannot protect against fine particle pollutants such as pm2.5. At present, a better solution is to set a plastic breathing valve on the mask. The heat of the exhaled air is discharged through the breathing valve, and the temperature inside the mask is reduced, reducing the accumulation of hot and humid air inside the mask. However, this breathing valve cannot actively increase the breathability of the mask, and the wearer will still feel very suffocated. For the masks currently on the market, the filtration efficiency and the breathing resistance cannot be balanced. The contradiction between these two aspects restricts the maximum effect of the dust masks, and cannot meet the needs of people's comfort. For this reason, a research work on a dust-proof mask with an intelligent breathing ring was carried out. The purpose is to solve the contradiction between the existing masks that cannot balance the filtration efficiency and air resistance, as well as the protection and comfort of the mask through comprehensive and systematic experiments and analysis. problem of poor sex.

Contents of the invention

The invention provides a dustproof mask with an intelligent breathing ring, aiming at the prior art to solve the problem that the existing mask cannot balance the filtration efficiency and air resistance, and the mask has poor protection and comfort.

Technical scheme of the present invention is as follows:

1. A dust-proof mask with an intelligent breathing ring, comprising a mask and an intelligent breathing ring, both of which are detachably connected by screw buckles, and the mask is provided with a breathing ring base for installing an intelligent breathing ring. The center of the breathing ring base is provided with a fixed shaft. The outside of the smart breathing ring is a transparent organic plastic cylinder, and the inside of the smart breathing ring includes diversion fan blades, magnetic bearing motors, filter cotton nets, diversion grille covers and filter Efficacy ring, the filtering effect ring is buckled and connected to the diversion grille cover, the two ends of the magnetic bearing motor are respectively connected to the filter cotton net and the diversion fan blade, and the fixed shaft of the base of the breathing ring is passed through to form a whole. Driven by a bearing motor, it is embedded in the diversion grid cover, mechanically connected and assembled into a small fan, which introduces filtered air into the mask, and the blades of the diversion fan are installed on the output shaft of the magnetic bearing motor.

Described a kind of dust-proof mask with intelligent breathing ring, its preferred solution is that the intelligent breathing ring of the dust-proof mask can be disassembled and replaced, and the diameter of the external structure is 4cm and the height is 2cm.

The preferred solution of the dustproof mask with an intelligent breathing ring is that the filtering effect ring is composed of a transparent plexiglass ring on the fixed cover, and is equipped with a four-degree color scale from white to gray.

The dust-proof mask with an intelligent breathing ring, the preferred solution is that the filter cotton net is composed of five layers of filter material layers to filter air pollutant particles, and the five layers of filter material layers are respectively non-woven fabrics from the outside to the inside. Cloth, activated carbon non-woven fabric, needle-punched cotton non-woven fabric, electrostatic high-efficiency filter material and non-woven fabric layer.

The dust-proof mask with an intelligent breathing ring is preferably provided with four gears for the small fan, and the current limiting resistor adjusts the number of revolutions of the fan to control the air intake of the intelligent breathing ring. The number of revolutions of the fan is changed from 1000 to /min, 1300rpm, 1600rpm and 2000rpm correspond to child mode, elderly mode, adult mode and sports mode respectively.

The working principle of the present invention is as follows: the magnetic bearing motor drives the blades of the deflector fan to rotate, and the number of revolutions of the fan is controlled to change between 1000-2000/min through the four-speed current limiting resistor to generate different air intake volumes. The motor unit is powered by two AAA batteries. The power supply is an external power box, which is combined with the mode control panel. It is convenient to control and reduces the weight of the smart breathing ring. Driven by the blades of the diversion fan, the external air enters in a vortex shape from the diversion grille cover. After being filtered by five layers of filter cotton, the clean air is brought into the inside of the mask, which increases the air intake of the mask and at the same time makes the inside of the mask form a Positive wind pressure increases the protective effect of the mask.

Beneficial effects of the present invention: the technical solution of the present invention is simple to manufacture and easy to implement, and solves the problem that the existing masks cannot balance the filtration efficiency and air resistance, and the masks have poor protection and comfort. In this invention, the blades of the guide fan are driven to rotate through the magnetic bearing motor, and different air intake volumes are generated through the four-speed current-limiting resistor. The combination of the external power box and the mode control panel makes the control convenient and reduces the weight of the smart breathing ring. After being filtered by five layers of filter cotton, clean air can be brought into the mask to ensure soft air intake and not interfere with the user's normal breathing. The filter effect ring allows the user to visually see the color change of the filter cotton net. When it reaches four shades of gray, replace the filter cotton net to ensure the filtering effect of the breathing ring. The present invention not only increases the filtering effect of the dustproof mask, but also effectively reduces the breathing resistance of the mask, effectively eliminates the stuffy feeling of wearing the mask, and improves the protection and comfort of the mask. The smart breathing loop mask is especially suitable for people who are doing outdoor sports or labor, and ensures the high-frequency breathing air volume of the human body during exercise. The entire intelligent breathing ring has a simple structure, and the plastic parts are light in weight, and it is easy to assemble, maintain and replace by means of screw buckles. Therefore, adopting this structure has significant economic benefits.
