Problems solved by technology

As we all know, the main index of wearing comfort is not only the material softness of the mask, but also the air permeability of the mask, and there is an irreconcilable contradiction between the air permeability and the protective effect. It is difficult for a mask with good air permeability to guarantee the protective effect, and the improvement of the protective effect will inevitably decrease. Air permeability, because of this, all kinds of existing masks are difficult to achieve both air permeability and protective effect, and achieve satisfactory results

Embodiment 1

[0033] Such as figure 1 As shown, the mask structure designed by the present invention mainly includes a mask body 1, ear straps, a retaining member 2 located inside the mask body, and an air grid box 3 clamped inside the retaining member 2. Among them, the main body of the mask 1 is arched as a whole, matching the shape of the human face. When worn on the human face, there is a certain gap between the inner wall of the central part and the human skin. On the one hand, it avoids direct contact with the skin, which affects comfort. On the other hand, it provides space for the circulation and retention of air, making breathing more convenient. The entire mask body is stamped and formed by a mold at one time, and its structure includes an inner filter membrane and an outer fabric. In order to ensure the protective effect, the inner filter membrane is generally made of melt-blown cotton, non-woven fabric, sponge, cotton cloth or chemical fiber. It is better to use an anti-PM2.5 f...

Embodiment 2

[0040] The difference between embodiment 2 and embodiment 1 is that there are two air grid boxes in total in this embodiment, and the two air grid boxes can be connected together and clamped in the middle of the clamping position, or can be clamped separately in the clamping position on two opposite side walls of the piece. In order to adapt to the overall shape of the mask, when the two air grid boxes are connected together, the structure is as follows Figure 7 As shown, the two air grid boxes are set at an angle of 60° to 120°, and the edges of the two air grid boxes are snapped into the annular support wall 5 of the clamping piece, and then the clamping piece is welded by ultrasonic sewing technology. Press on the central part of the inner wall of the mask body, corresponding to the position of the mouth and nose of the person. Inside the two air grid boxes, a micro fan is installed respectively. The two micro fans are connected to the external mobile power supply through...

Abstract

The invention discloses a cavity type mask with an oxygenation function and mainly solves the problems that masks cannot give consideration to both protective effects and breathability in the prior art. The mask comprises a mask body (1) and ear loops connected to two ends of the mask body (1). The mask is characterized in that the a clamp part (2) is welded and pressed to a position, corresponding to the mouth and nose of a person, of the inner side of the mask body (1) through ultrasonic sewing, the clamp part is a sealed ring, and the air gate box (3) of a built-in micro-fan (4) is clamped to the middle opening of the clamp part. The cavity type mask is ingenious in design, convenient to mount and maintain, good in application effect and high in practical value.

Description

[0001] technical field [0002] The invention relates to a mask, in particular to a cavity-type mask with an oxygen increasing function. Background technique [0003] Masks are generally used to be worn on the nose and mouth of people to filter the air in the nose and mouth, so as to block harmful gases, odors, and droplets. The materials are mostly cloth or paper. In order to ensure health and safety, masks are usually discarded directly after multiple uses. The structure of the mask usually consists of a mask body and ear straps. The mask body functions to filter and block harmful substances, while the ear straps play a role in fixing the mask body on the human ear or head to prevent it from falling. [0004] Medical protective masks have stricter requirements than ordinary masks. The main body of the mask is divided into three layers: inner, middle and outer. Layers of non-woven or ultra-thin polypropylene meltblown material. In some harsh environments, such as: infect...
