Abstract
Description
Technical fields:
[0001] This utility model relates to the field of respiratory mask technology, and in particular to a composite respiratory mask. Background technology:
[0002] In enclosed spaces, the natural breathing of users causes localized increases in air humidity, which can affect the normal operation of humidity-sensitive devices. For example, in cold weather, the increased humidity from exhaled air inside a helmet can cause condensation on the lenses, affecting the user's vision. Therefore, it is necessary to design a system to guide exhaled air to a designated area, thereby reducing the impact of exhaled air on the target area.
[0003] Because the face has a complex three-dimensional shape and everyone's bone structure is different, there are many challenges in designing a mask system. One important challenge is that the mask must be able to effectively seal the user's face.
[0004] Commercially available face masks typically achieve a seal by adapting to the user's face through the elastic deformation of elastic materials. These sealing surfaces are usually made of elastomers such as rubber or silicone. Because users have different facial contours, the sealing surface cannot perfectly fit every user's face. To ensure a seal, users often have to overtighten the headband or other methods to apply pressure to the mask. Since elastic materials are not breathable, prolonged wear may cause skin discomfort, and sweat can reduce the seal.
[0005] Commercially available face masks are typically bulky and supported by numerous rigid structures. These masks are generally too bulky to be suitable for use in confined spaces. Utility model content:
[0006] The technical problem to be solved by this utility model is to provide a composite breathing mask that can guide the exhaled air out, avoid the condensation of the lens affecting the user's vision, has a reasonable structure, fits the face better, is suitable for different face shapes, greatly reduces the size, and can be worn in confined spaces.
[0007] The technical solution adopted by this utility model is: a composite breathing mask, including a mask body that covers the mouth and nose of the human body; the mask body is an elastic support mask body, the upper end of the mask body is provided with an elastic groove, the mask body is provided with air inlet interfaces for connecting air inlet components on both sides of the nose, and the lower part of the mask body is provided with an air outlet interface for connecting air outlet components on the mouth.
[0008] The air intake assembly includes an air intake valve assembly, a multi-functional base, and a multi-functional accessory. The air intake valve assembly includes an air intake inner shell disposed inside the mask body and an air intake valve disposed on the air intake inner shell. The air intake inner shell is connected to the multi-functional base. The air intake interface is clamped between the air intake inner shell and the multi-functional base and is limited and connected. The multi-functional accessory is installed on the multi-functional base.
[0009] The air outlet assembly includes an air outlet valve assembly, an air outlet guide housing, and a multi-functional connector. The air outlet valve assembly is located inside the mask body and is connected to the air outlet guide housing. The air outlet is sandwiched between the air outlet valve assembly and the air outlet guide housing and is limited and connected. The multi-functional connector is installed at the lower end of the air outlet guide housing.
[0010] Furthermore, the main body of the mask is made of silicone, rubber, elastic plastic, silicone grease, resin or polyester material.
[0011] Furthermore, the mask body has a soft, fitted frame edge that conforms to the human face.
[0012] Furthermore, the intake valve includes an intake valve plate base and an intake valve plate mounted on the intake valve plate base.

[0038] The main body of the mask 1 is made of silicone, rubber, elastic plastic, silicone grease, resin or polyester material.
[0039] The mask body 1 has a soft, fitted frame 23 that fits snugly against the human face.
[0040] The intake valve includes an intake valve base 11 and an intake valve plate 9 mounted on the intake valve base 11.
[0041] like Figure 8 As shown, the intake valve plate base 11 is provided with an intake channel protection support limit block 20.
[0042] The air inlet of the mask body 1 is provided with an air inlet limiting protrusion 13, which extends into the limiting groove on the air inlet inner shell and the multi-functional base 3 to achieve limiting; the air outlet of the mask body 1 is provided with an air outlet limiting protrusion 12, which extends into the limiting groove on the air outlet valve assembly 5 and the air outlet guide shell 7 to achieve limiting.
