Problems solved by technology

[0004] 1. The mask adopts a self-priming filter method, and the breathing is not smooth, especially after the mask absorbs dust particles;
[0005] 2. The mask and the human face cannot be completely fit, there is a gap, and negative pressure is formed near the mouth when inhaling, and the effect of dust and virus is not good; the current masks mostly use activated carbon to absorb and pay, and the activated carbon itself is also fine particles. Improper use will become a source of pollution;
[0006] 3. The service life of the mask is short, usually it must be replaced after 1-3 days of use, and the cost of use is high

Embodiment 1

[0029] Such as figure 1 The high-clean mask shown includes a sequentially connected cleaning device, a breathing tube and a mask body; the clean device includes a sequentially connected power supply device, an air pump and a filter cup, the air pump and the filter cup are connected through an air intake pipe, and the filter cup Filtrate is arranged inside, the intake pipe is submerged in the filtrate, the filter cup is connected with the breathing tube, and the breathing tube is located above the filtrate.

[0030] An anion generator is installed between the filter cup and the breathing tube; a filter cotton and a breathable water baffle are installed in the filter cup and above the filtrate; a pressure sensor is installed between the air pump and the filter cup; a stop valve is installed on the intake pipe The height of the filtrate is 5 / 1 of the height of the filter cup; the air inlet of the air intake pipe and the end of the air intake pipe immersed in the filtrate are prov...

Embodiment 2

[0035] It is basically the same as Example 1, except that the mask body filter material is made of ordinary non-woven fabric (purchased from Xianghe County Huitong Nonwoven Co., Ltd.); the height of the filtrate is 3 / 1 of the height of the filter cup; sodium carbonate particles The content is 100g / m 2 The filtrate is a mixed solution of nano-silver and sodium carbonate, in the mixed solution: the content of nano-silver is 0.1mg / L, and the content of sodium carbonate is 8g / L.

[0036] The filtration efficiency of the obtained high-clean mask reaches 99.9%, which can filter the dust very well; the air supply is sufficient and the breathing is smooth (the test refers to the GB2626-2006 standard); the mask and the face are completely compliant, without gaps; the filter liquid is based on the usage It can be replaced every 1-2 months.

[0037] The antibacterial rate of the mask is greater than or equal to 50% (refer to GB21551.3-2010 Special requirements for antibacterial, sterili...

Embodiment 3

[0039] It is basically the same as Example 1, the difference is:

[0040] The filter material of the mask body is made of ordinary non-woven fabric (purchased from Xianghe County Huitong Nonwoven Co., Ltd.); the height of the filtrate is 4 / 1 of the height of the filter cup; the filtrate is a rosin glyceride emulsion with a solid content of 5%.

[0041] The emulsifier used in the emulsion is a rosin-based emulsifier, and the preparation method of the rosin-based emulsifier is as follows: under the catalysis of magnesium oxide, maleic rosin and polyethylene glycol 6000 are reacted for 3.5 hours at a temperature of 240-250° C. Press and vacuum; then add hydroquinone and phosphorus pentoxide, and react at 80-90°C for 4.5 hours to obtain a rosin-based emulsifier. The mass ratio of maleic rosin to polyethylene glycol 6000 is 1:4, oxidized The mass dosage of magnesium is 0.8% of the maleic rosin quality, the mass dosage of hydroquinone is 0.3% of the maleic rosin quality, and the mas...

Abstract

The invention discloses a high clean mask which comprises a clean device, a breathing tube and a mask body which are sequentially connected, wherein the clean device comprises a power supply device, an air pump and a filter cup which are sequentially connected; the air pump is connected with the filter cup by an air inlet tube; a filtrate is arranged in the filter cup; the air inlet tube is immersed in the filtrate; the filter cup is connected with the breathing tube; and the breathing tube is located above the filtrate. The high clean mask is simple in structure, convenient to use, long in service life, sufficient in air supply and smooth in breathing; the filtration efficiency reaches above 99%; dust is filtered very well; and the mask is fit with a face completely without clearance.

Description

technical field [0001] The invention relates to a high-clean mask. Background technique [0002] At present, my country's anti-dust masks adopt the "GB2626-2006 standard for self-priming filter-type anti-particulate respirators for respiratory protective equipment". The various quality requirements of this standard are consistent with the current international American standards. In the standard, the protection level of dust masks (anti-oil particles) is divided into three types: N100 (dust-proof rate above 99.97%), N95 (95% above), N90 (90% above); masks on the Chinese market The products are mainly N95 grade. N95 mask refers to one of the 9 dust masks certified by NIOSH (National Institute of Occupational Safety and Health), where "N" means that its material is only suitable for filtering non-oily particles, while "95" means its filtering efficiency Up to 95%. The particles filtered by N95 masks can be as small as 0.3 microns in diameter. [0003] There are some follow...
