Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire escape tools, in particular to an emergency rehumidifying respirator. Background Art
[0002] With the progress and development of society, various industries have undergone new qualitative changes in production, transportation, life, etc., especially in high-rise buildings. There are many places where people gather, such as schools, hospitals, residences, shopping malls, and restaurants that use insulation materials. As a result, sudden fire casualties occur frequently. Human life is only once, and no material can replace it. In view of the current application of new insulation materials, home decoration, furniture, and transportation vehicles mainly use a large number of wood and glued fiber molded products. Due to the addition of flame retardants, once a fire that cannot be extinguished and prevented occurs, it is very easy to produce a large amount of toxic smoke and heat. With the action of hot air flow and natural wind, it will affect neighbors and even high-rise rooms, endangering people's lives. The previous examples of people being choked to death by smoke show the importance of winning emergency escape every second. For this reason, an emergency rehumidification respirator with a simple structure, easy to carry, and corresponding to sudden fire is produced, which provides convenience for emergency escape of humans in outdoor venues, shopping malls, and residences.

[0004] The purpose of the utility model is achieved in this way:
[0005] An emergency rehumidifying respirator comprises an outer cover and a wet inner cover, wherein the outer cover is provided with ear straps on the left and right sides, and the wet inner cover is provided with pressure strips corresponding to the ear straps on the left and right sides, and the upper and lower ends of the pressure strips are fixed on the wet inner cover to form buckles, the outer cover is formed by multiple layers of pure cotton yarns with different gram weights and different pore sizes to form a semi-rigid model body, and the wet inner cover is composed of multiple layers of pure cotton yarns with different pore sizes and different thicknesses, the wet inner cover soaked in water is built in a sealed can, and the sealed can with the built-in wet inner cover and the outer cover are packaged in a packaging box.
[0006] Preferably, a Velcro is provided between the outer cover and the wet inner cover, and the Velcro is provided at two locations, the upper and the lower, and the paired Velcro hook and loop surfaces are respectively fixed on the corresponding outer cover or the wet inner cover.
[0007] Preferably, the wet inner mask is provided with a nose bridge near the upper edge, and the nose bridge is built into the multiple layers of pure cotton yarn of the wet inner mask.
[0008] Preferably, the circumference of the wet inner cover is coated with a silicone sealant.
[0009] The beneficial effects of the utility model are:
[0010] The structure is simple and easy to carry. It adopts the dry and wet two-stage filtration method. The wet inner and outer covers can be quickly combined. When worn on the face, it covers the mouth and nose to block the inhalation of toxic smoke and dust, so as to achieve the purpose of quickly escaping from the incident site.
[0011] The outer cover is made of four layers of pure cotton yarn with different gram weights and pore sizes to form a semi-rigid model body, which makes the outer cover flame retardant; the wet inner cover is made of eight layers of pure cotton yarn with different pore sizes and different thicknesses, so that the product can filter different harmful substances in harsh accident environments.

[0018] See also Figure 1-5 The utility model relates to an emergency rehumidifying respirator, comprising an outer cover 1 and a wet inner cover 2. The outer cover 1 is formed of a semi-rigid model body made of four layers of pure cotton yarns with different gram weights and different pore sizes, so that the outer cover 1 has a flame retardant function. The wet inner cover 2 is composed of eight layers of pure cotton yarns with different pore sizes and different thicknesses, so that the product can filter different harmful substances in a harsh accident environment. The outer cover 1 and the wet inner cover 2 are buckled with each other, and ear straps 3 are provided on the left and right sides of the outer cover 1. The ear straps 3 are composed of elastic elastic bands, and the ear straps 3 can be made of nylon cotton. The left and right sides of the wet inner cover 2 are provided with pressure strips 4 corresponding to the ear straps 3. The upper and lower ends of the pressure strips 4 are fixed on the wet inner cover to form buckles. When in use, the ear straps 3 are passed through the buckles to achieve the buckling of the wet inner cover 2 and the outer cover 1.
[0019] A Velcro 5 is also provided between the outer cover 1 and the wet inner cover 2 to achieve rapid combination and positioning of the outer cover 1 and the wet inner cover 2. The Velcro 5 is provided at two upper and lower locations, and the paired Velcro hook and loop surfaces are respectively fixed on the corresponding outer cover 1 or the wet inner cover 2.
[0020] The wet inner mask 2 is provided with a nose bridge 6 near the upper edge, and the nose bridge 6 is arranged below the upper Velcro 5. The nose bridge 6 is made of metal material and is built into the multi-layer pure cotton yarn of the wet inner mask 2. When worn, pressing the nose bridge 6 with fingers can highlight the space in the mouth and nose area and the unobstructed respiratory tract.
[0021] The outer cover 1 and the wet inner cover 2 are circumferentially sewn. The wet inner cover 2 is also covered with a silicone sealing edge 7, which makes the wet inner cover 2 fit the face better, improves the overall sealing effect, and effectively blocks tobacco and toxic substances.
[0022] The wet inner cover 2 soaked in water is built into a sealed tank 8, and medicinal elements are added to the water to ensure that the wet inner cover does not deteriorate within the validity period. At the same time, after it expires without use, it can still be used after disinfection and replacement of liquid. The sealed tank 8 with the built-in wet inner cover 2 and the outer cover 1 are packaged in a packaging box 9 for easy storage and transportation.
[0023] The sealed tank 8 is of straight-insert or screw-on type, and includes a sealed tank body 8.1 and a sealed cover 8.2, which can be used to quickly retrieve items and can be used by blind people. The sealed tank body 8.1 is made of an integrally-injected transparent material. The wet inner cover 2 is immersed in the sealed tank 8 with water when not in use. The sealed tank body 8.1 and the sealed cover 8.2 have good sealing properties and will not leak when inverted.
[0024] When in use, remove the packaging box 9, take out the wet inner cover from the sealed can, assemble the wet inner cover and the outer cover, press the Velcro 5, quickly combine and position the outer cover 1 and the wet inner cover 2, and at the same time pass the ear strap 3 through the buckle to achieve the buckle of the wet inner cover 2 and the outer cover 1, and quickly hang the ear strap on the ear. The whole process only takes 10-15 seconds, which buys time for emergency escape.
[0025] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
