Dust and gas masks {A dust proof and anti-gas mask}

The present invention relates to an anti-dust and anti-gas mask, and more particularly, by improving the connection structure of a plurality of filters connected to the anti-vibration and anti-gas mask, it becomes easier to attach and detach each of the filters connected to each other, By making it more firmly connected, it prevents the risk of damage to each filter when using the dust and gas masks. In addition, the number of filters can be adjusted to suit the surrounding conditions where the dust and gas masks are used. The present invention relates to a dustproof and antigas mask for allowing the purification function to be significantly improved.

In general, a lot of dust is generated in the working environment of paper mills, textile mills, quarries, etc. In addition, a large amount of toxic gas is generated in the working environment of various chemical plants and metal processing plants such as welding, smelting, plating. Since dust and toxic gases can be fatal to workers' health, workers who work at hazardous work sites are now prevented from being exposed to hazardous work environments by wearing dust and gas masks.

Conventional dust and gas masks are coupled to the mask body and the mask body formed of a flexible flexible mask to shield the nose and mouth of the operator and removable filter on the front surface of the mask body and to filter foreign substances flowing into the mask and the mask body It consists of a band to fix the mask body to the head.

However, the conventional dust and gas masks configured as described above have a problem in that the performance of the purification filter is degraded when used for a long time, so that the original functions of the filter cannot be performed.

In order to solve this problem, Korean Patent Laid-Open Publication No. 1998-033553 includes a mask body, a filter housing formed on one side of the lower side of the mask body, and a filter cylinder coupled to the filter housing. In the gas mask, a dust mask and a gas mask are disclosed, characterized in that the filter cylinder is accommodated with a porous mica-filled nonwoven sac filled with mica heated at a high temperature of 900 to 1,100 ° C. for 2 to 4 seconds.

However, the above applied technology improves the performance of the filter used in the purification filter, but since only one filter is formed in the purification filter, there is no disclosed structure for connecting a plurality of filters. There was a problem that can not be used, there is a problem that can not purify the air flowing in and out of the dust and gas mask by using a single filter more effectively, and also the purification filter connected to the mask body when using the mask can be easily damaged There was a problem.

The present invention has been made to solve the problems described above, the object of the present invention is to facilitate the detachment of each filter connected to a plurality of filters by improving the connection structure of a plurality of filters connected to the dust and gas mask. In addition, by making each filter more firmly connected, the purpose is to prevent the risk of damage to each filter when using the dust and gas masks. In addition, the number of filters is adjusted to suit the ambient conditions in which the dust and gas masks are used.

Therefore, a user who wants to wear a mask adheres the first filter 200 to one side of the filter accommodating part 210 formed on the mask body 1 and then the fitting plate formed on the filter accommodating part 210. The first filter 200 is connected to the filter accommodating part 210 by fitting and fitting one end of the 211 to the fitting protrusion 203 of the first filter 200 while moving from the upper side to the lower side.

In addition, as in the first embodiment, it is also possible to sequentially connect two or three or more filters 200 to the filter accommodating part 210 in addition to one filter 200.

That is, the other side of the first filter 200, the insertion plate 201 is formed at equal intervals along the outer circumferential surface, if the user wants to connect the second filter 200, the insertion plate 201 to the second filter 200 The first filter 200 and the second filter 200 are sequentially connected to the filter accommodating part 210 by fitting to the fitting protrusion 203 formed at

As described above, in the second embodiment of the present invention, the first filter 200 and the second filter 200 are connected to the filter accommodating part 210 so that the plurality of filters 200 are sequentially connected to the inside and the outside. It is effective to purify the air flowing in and out more efficiently, and each filter 200 using the fitting plate 201 and the fitting protrusion 203 in addition to the locking ring 101 and the locking jaw 107 described in the first embodiment. ), It is effective to improve the diversity of the connection structure.

In the fastening structure according to the third embodiment of the present invention, as shown in FIGS. 4 and 8, the male screw part 311 is formed on one side of the filter accommodating part 310 formed below the mask body 1, and One side of the first filter 300 to be connected to the filter accommodating part 310 forms a female thread part 305 so that the filter accommodating part 310 is formed by screwing the male thread part 311 and the female thread part 305. ) To the first filter 300.

In addition, like the first and second embodiments, in the third embodiment, a plurality of filters 300 may be sequentially connected to one filter 300.

That is, the male screw part 301 is formed on the other side of the first filter 300 connected to the filter accommodating part 310, and the female screw part 305 is formed on one side of the second filter 300 so that the number of the first filters 300 may be reduced. By screwing the female threaded portion 305 of the second filter 300 to the threaded portion 301, the first filter 300 and the second filter 300 are connected to each other so that the plurality of filters 300 are sequentially connected.

Therefore, in the present invention, the female screw portion 305 and the male screw portion 301 are formed at one side and the other side of the first filter 300, and the female screw portion 305 and the male screw portion (305) are formed at one side and the other side of the second filter 300. 301 is formed, the female screw portion 305 of the first filter 300 is screwed to the male screw portion 311 of the filter accommodating portion 310, the male screw portion 301 of the first filter 300 is The first filter 300 and the second filter 300 are connected to each other by screwing the female screw 305 formed in the second filter 300.

Through this process, the third filter 300 may also be connected to the second filter 300, and the third embodiment may also improve the structural stability of the connected filter 300 by allowing the plurality of filters 300 to be sequentially connected more conveniently. In addition, there is an effect that can improve the air purification efficiency of the dust and gas mask.

In addition, by connecting each filter 300 using the female screw portion 305 and the male screw portion 311 there is an effect that can improve the diversity of the connection structure.
