Embodiment 1

[0013] Antibacterial mask filter, the schematic diagram is as follows figure 1 Shown in middle 2, the present embodiment is that the antibacterial, anti-ultraviolet effect filter is used in combination with the three-dimensional mask, and the combination includes a three-dimensional mask 1, a filter 2 with antibacterial effect, and an adhesive strip 3 connecting the mask and the filter , the filter adopts the bamboo fiber melt-blown cloth layer with phthalocyanine photosensitive material as the middle layer. and Candida albicans) in 15 minutes - 1 hour to achieve a kill rate of 70% - 99%. Bamboo fiber melt-blown cloth mainly uses bamboo fiber as raw material, and its anti-ultraviolet efficiency reaches 99.4% - 99.8%.

Embodiment 2

[0015] PM2.5 anti-ozone / VOC (harmful gas) protective mask filter, the schematic diagram is as follows figure 1 As shown in middle 2, the present embodiment is a combination of a filter with filtering, antibacterial and anti-ultraviolet effects and a three-dimensional mask; the combination includes a three-dimensional mask 1, a filter 2 with filtering, anti-ozone / VOC, and anti-ultraviolet effects And the adhesive strip 3 connecting the mask and the filter; the filter 2 uses electretized melt-blown non-woven fabric as the middle layer, and the melt-blown non-woven fabric treated with electret technology enhances the electrostatic adsorption performance, and is fine to 0.3 microns The particle filtration efficiency reaches 95%-99%, including anti-VOC gas and ozone protection materials, which can effectively block the inhalation of harmful gases.

Embodiment 3

[0017] Antibacterial filter mask filter, its schematic diagram is as follows figure 1 As shown in middle 2, the present embodiment combines antibacterial and PM2.5 filter sheets with a three-dimensional mask, and the combination includes a three-dimensional mask 1, a filter 2 with antibacterial effect and a rubber strip 3 connecting the mask and the filter, The filter sheet 2 has a three-layer structure, which is the outer layer of bamboo fiber melt-blown non-woven fabric, the middle layer of electretized melt-blown non-woven fabric, and the inner layer of polypropylene spunbonded non-woven fabric. The filtration efficiency of 0.3 micron fine particles reaches 95%- 99%, for common pathogenic bacteria (including but not limited to Staphylococcus aureus, Escherichia coli and Candida albicans), the killing rate is 70% - 99% within 15 minutes - 1 hour.

[0018] Schedules 1 and 2 It is the antibacterial test result of the filter sheet in the patent example of the present inventio...

Abstract

The invention discloses an anti-microbial mask filter element for effectively filtering out PM2.5 particulate matter. Compared with common filter elements and masks, the filter element is of a three-layer structure, an outer layer is a bamboo fiber meltblown non-woven fabric where a zinc phthalocyanine light-sensitive material attaches to, a middle layer is a polarized meltblown non-woven fabric, and an inner layer is a polypropylene spunbonded non-woven fabric. The anti-microbial mask filter element can effectively filter out the PM2.5 particulate matter, effectively kill bacteria and prevent secondary pollution and is uvioresistant. In addition, the filter element can adhere to the inner layers of a stereoscopic mask, a disposable mask and other types of masks through movable adhesive tape colloidal particles, can be combined with other common masks in use and is simple and practical in operation.

Description

technical field [0001] The invention belongs to the category of health care, in particular to a mask filter which is antibacterial and effectively filters PM2.5 particles. Background technique [0002] The mask is a kind of sanitary protection product widely used in various occasions. The main functional part of the mask is the filter. The filter on the market is mainly a filter with a filtering function. The filter can block PM2.5 particles in the air, but it is The filtered particles and bacteria are easy to attach to the mask (filter) close to the mouth and nose, causing the growth of bacteria, forming secondary pollution, and then penetrating into the human body through the mask (filter), causing harm to the human body and unhygienic It also reduces the protection and antibacterial effect of the mask. The antiseptic masks on the market cannot effectively filter out PM2.5 particles, which can carry bacteria into the human respiratory system, and the process of killing ba...
