Embodiment 1

[0047] like Figure 1~Figure 5 It can be seen that the breathing valve body structure of a kind of inhaling and exhaling filter-type mask of the present invention includes a mask body 1 with ear hanging devices A2 respectively on both sides, and a breathing valve body 8 is provided on the inside of the mask body 1, so that The breathing valve body 8 is provided with an air inlet 28, an air outlet 14 and a breathing port 13 corresponding to the user's nostrils. The mouth mask body 1 includes a multi-layer composite filter layer 31 and a hygroscopic layer 32 successively from the outside. The mouth mask body The edge of 1 is sealed and fixed, so that the edge positions between the layers of the mask body 1 are respectively sealed and fixed. The middle part of the mask body 1 is provided with a transverse welding mark A22, and the transverse welding mark A22 makes the mouth mask body 1 The welding marks A22 positions between the layers are respectively sealed and fixed, and the a...

Embodiment 2

[0076] like figure 1 , image 3 , Image 6 and Figure 7 It can be seen that the breathing valve body structure of a kind of inhaling and exhaling filter-type mask of the present invention includes a mask body 1 with ear hanging devices A2 respectively on both sides, and a breathing valve body 8 is provided on the inside of the mask body 1, so that The breathing valve body 8 is provided with an air inlet 28, an air outlet 14 and a breathing port 13 corresponding to the user's nostrils. The mouth mask body 1 includes a multi-layer composite filter layer 31 and a hygroscopic layer 32 successively from the outside. The mouth mask body The edge of 1 is sealed and fixed, so that the edge positions between the layers of the mask body 1 are respectively sealed and fixed. The middle part of the mask body 1 is provided with a transverse welding mark A22, and the transverse welding mark A22 makes the mouth mask body 1 The welding marks A22 positions between the layers are respectivel...

Abstract

The invention discloses a breathing valve body structure of an inhaling and exhaling separate-filtering mask. A breathing valve body is arranged on the inner side of a mask body, the breathing valve body is provided with an air inlet, air outlets and breathing ports corresponding to nostrils of a user, and the air outlet communicates with an air pipe A; two partition plates are correspondingly andsequentially arranged in the breathing valve body in the direction from the middle to the two sides, the breathing valve body is separated into five cavities by the partition plates, the middle cavity is an air inlet cavity, the two cavities adjacent to the air inlet cavity are transition cavities, the cavities adjacent to the sides, facing the air inlet cavity, of the transition cavities are airoutlet cavities, the air inlet is formed in the air inlet cavity, the air outlets are formed in the air outlet cavities, and the breathing ports are formed in the tops of the transition cavities. According to the breathing valve body structure of the inhaling and exhaling separate-filtering mask, the air inhaled and exhaled from the nostrils enter and exit the breathing valve body through different paths, so that the inhaled and exhaled air is separated into different disconnected areas for filtration.

Description

technical field [0001] The invention relates to the technical field of a filtering mask, in particular to a breathing valve body structure of an inhaling and exhaling filter mask. Background technique [0002] Mask is a kind of sanitary product, which generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. Spray cloth or paper, etc. made. [0003] Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. [0004] At present, most of the masks on the market are air-filtering masks, which filter the air inhaled into the human body through the fabric structure of the mask, and also filter the exhaled gas from the human body and then discharge it to the outside world. [0005]...
