The present invention provides a separable mouth and nasal cavity mask. As shown in Figure 1, the separable mask is mainly divided into two parts: a mask body and an earmuff cord; It is composed of woven fabrics and other fabrics. The cover is composed of the upper part 6, the middle part 7 and the lower part 8 of the cover body from top to bottom; the upper earmuff rope 2 and the lower earmuff rope 3 are respectively provided on both sides of the cover body. One end of the upper earmuff cord 2 is set on the upper side of the upper part 6 of the cover body, the other end is set on the upper side of the middle part 7 of the cover body, one end of the lower earmuff cord 3 is set on the lower side of the middle part 7 of the cover body, and the other end is set on the lower side of the middle part 7 of the cover body. The lower side of the lower part 8 of the cover.

The upper part 6 of the mask body is rectangular, and the upper side is provided with a nose clip 1. Most disposable masks on the market include this design. When the user wears a mask with separated mouth and nasal cavity, the nose clip 1 can be manually operated and shaped , It is used to prevent the gas outside the separated mask from entering the mouth and nasal cavity separated mask through the gap between the upper edge of the separated mask and the user’s face, which may cause health problems and dangers; there is also a place on the upper part 6 of the mask body Folding part 4, most of the disposable masks on the market include this design. When the user wears the mask, the folded part 4 is stretched to create a larger cover area and better cover the mouth and nose of the user to achieve Good protection for the user, the cover is flat in the idle state, which is convenient for storage and transportation.

The middle part 7 of the cover body is a long rectangle, and its outer side (or inner side-if the rubber band structure is wrapped by a fabric or its own material does not stimulate the skin, such as silicone rubber, etc.) is glued with a rubber band structure 5 of the same shape as the middle part 7 of the cover body. Here, the rubber band structure 5 can also be sewn on the outside of the middle part 7 of the mask body, or the rubber band structure 5 can be arranged inside or inside the middle part 7 of the mask body as described above; The tightening effect of the rib structure 5 is matched with the design of the double earmuffs on both sides of the mask body, so that the middle part of the mask body is well attached to the upper lip, so that the nose and mouth of the mask wearer can be isolated from each other. The lower part 8 of the cover body is rectangular and is provided with two (or more) folding parts 4, which have the same function as the folding part 4 of the upper part 6 of the cover body.

The present invention provides a separable mouth and nasal cavity mask. The separable mask is provided with an isolation structure at the middle part 7 between the upper part 6 of the mask body and the lower part 8 of the mask body. 6 covers the nose, and the lower part of the mask body 8 covers the oral cavity. The mouth-nasal cavity separation mask realizes the isolation between the nose and the oral cavity through the isolation structure. Humidity and odorous gas is mainly the gas exhaled by the mouth. Through the isolation effect, the nose does not need to inhale the humid and odorous old gas exhaled from the oral cavity. At the same time, the volume of the cavity where the nose is located is reduced, and the gas exhaled by the nose can also be used. Exhale the upper part of the mask well instead of being inhaled by the nose next time. The comfort of the user is greatly improved. Therefore, it solves the problem that the user inhales a large amount of old gas with humidity and smell, especially oral gas, which is exhaled last time. The problem of discomfort that appears; it solves the problem that the user takes off the mask and tries to breathe fresh air because of the discomfort of wearing the mask for a long time. When the user is in a polluted environment, this is very unhealthy and even dangerous; the nose is isolated from the mouth, The nose will not be able to inhale the bacteria growing on the inside of the lower part 8 of the mask, thereby solving the problem that the moist and odorous gas exhaled from the mouth can breed bacteria on the inside of the mask. Inhaling bacteria when inhaling through the nose may cause nausea and health problems for the user; exhaling from the nose The relative humidity of the gas is low and the odor is small, so the upper part 6 of the mask body can be kept dry for a long time and almost odorless; through the isolation effect, the nose cannot inhale the smell attached to the lower part of the mask body 8 due to oral air, increasing the reuse of the mask Therefore, it only solves the problem that after the mask has been used once, wearing it again without certain treatment may cause discomfort, and throwing it away will cause a waste of resources and is not environmentally friendly.

As a preferred embodiment of the oral and nasal cavity separation mask, as shown in Figure 2, the material of the mask body of the separation mask is relatively hard. For example, the existing N95 mask can be pasted with a silicone rubber structure 9 inside the mask body, or it can be used The method of sewing, the silicone rubber structure 9 is less irritating and elastic to the skin. The silicone rubber structure 9 can help close to the upper lip and isolate the mouth and the nose from each other. The upper part 6 of the cover body and the lower part 8 of the cover body Air valves 10 can be provided separately, which can help the user to better exhale the old gas with a certain humidity and smell, so as to achieve a better ventilation effect and increase the comfort during use.
