Embodiment 1

[0045] Example 1, such as figure 1 The shown emergency mask includes several mask monomers 1 with at least a waterproof outer layer, a middle filter layer, and a water-absorbing inner layer. Rolled into a reel 100, or several mask monomers 1 are stacked into bundles 200, the left and right ends of the mask monomer 1 are not provided with ear loop holes, and the nose bridge strips are not provided at the head end or tail end. Two adjacent mask monomers 1 are connected through intermittent holes so as to be suitable for tearing.

Embodiment 2

[0046] Embodiment 2, a kind of protective cover based on embodiment 1 emergency mask, as Figure 2-8 shown, including

[0047] Hard cover body 3, described hard cover body 3 is roughly bowl-shaped, and the bowl of described hard cover body 3 is provided with two belt rings 31 symmetrically along the outer side, offers a hole in the bottom wall of described hard cover body 3 32. The shape of the hole 32 is a special shape composed of a superior arc and a corresponding chord;

[0048]Silicone cover 4, the silicone cover 4 is also roughly bowl-shaped, the bowl edge of the silicone cover 4 is suitable for covering the mouth and nose, and the bottom wall of the silicone cover 4 is provided in the same shape as the hole 32 Hole 2 42, the bottom wall and part of the side wall of the silica gel cover 4 are suitable for being embedded in the hard cover 3;

Abstract

The invention relates to the epidemic prevention articles, in particular to an emergency mask and a protective cover based on the same. The emergency mask comprises a plurality of mask single bodies which are at least provided with waterproof outer layers, middle filtering layers and water absorption inner layers. The peripheral edges of the mask single bodies are heat-sealed and are connected endto end to form a whole, the waterproof outer layer is rolled outwards to form a winding drum, or the plurality of mask single bodies are stacked into a bundle. The mask is characterized in that ear rope holes are not formed at the left ends and the right ends of the mask single bodies, and nose bridge strip notches are not formed at the head ends or the tail ends of the mask single bodies. Compared with the prior art, the emergency mask is not provided with a hanging rope and a shaping aluminum strip, the mask cloth does not need to be folded for three times, so that the materials are saved,the processing is easy, the cost is lower, and the production efficiency is higher. The emergency mask can be supplied in a volumed manner, can be torn down like toilet paper for use, can replace an existing common mask, and is quite suitable for various sudden epidemic situations including new coronavirus.

Description

technical field [0001] The invention relates to anti-epidemic supplies, in particular to an emergency mask and a protective cover based on it. Background technique [0002] Since the outbreak of the new crown pneumonia virus in early 2020, masks, as basic epidemic prevention supplies, have been in short supply. Even many front-line medical staff lack masks for protection. People cannot travel and work because they cannot buy masks. The maximum production capacity of masks in my country is 20 million per day, while the current market demand is about 1 billion per day, with a 50-fold difference between supply and demand. Even the huge factory of Kolmi Hopen in France has an annual production capacity of only 170 million units, which is equivalent to a daily output of 500,000 units. It is impossible to deliver the 500 million orders received from China that need to be delivered immediately. Even if you order the production line immediately and invest in the expansion of the ma...
