Description

Technical Field

[0001] The utility model relates to the technical field of medical masks, in particular to a medical mask. Background Art

[0002] Nowadays, masks often adopt an one-piece design. After such masks reach the end of their service life, the entire mask needs to be discarded, which results in a huge waste of mask use. Under normal circumstances, due to the relatively small public health threat, the production scale of meltblown cloth, the core material of masks, is also relatively small. At this time, once a large-scale epidemic occurs, it will be difficult to increase the production quantity of meltblown cloth in a short period of time, which will cause the price of meltblown cloth and masks to rise rapidly. This not only makes it difficult for ordinary people to use masks, but also causes a shortage of masks.

[0003] A medical mask disclosed in the Chinese utility model patent application disclosure CN214016101U, although the medical mask has the function of reducing the amount of meltblown cloth used and ensuring the airtightness of the mask, the medical mask still has disadvantages: First, when the medical mask is worn, the upper end of the mask and the nose and the two sides cannot fit very tightly together, and there will be a certain gap, resulting in viruses in the air entering the inside of the mask through the gap in some occasions, thereby causing occupational exposure and safety hazards; Second, the medical mask is made of meltblown cloth material, but it is difficult to achieve 100% filtration of particulate matter or microorganisms. When there is an unpleasant odor in the air, the meltblown cloth is difficult to shield, which may easily cause discomfort to people when used. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Embodiment 1:

[0026] See also Figures 1 to 6The utility model provides a technical solution: a medical mask, comprising a main body 1 and a sealing ring 2, with pressure strips 3 fixedly connected to the left and right sides of the sealing ring 2, the main body 1 is in a truncated cone shape, the main body 1 is made of breathable and water-absorbent material, the sealing ring 2 is fixedly connected to the outside of the wide side of the main body 1, the pressure strips 3 are symmetrically arranged in two upper and lower parts, and the arrangement of the pressure strips 3 makes the installation of the first ear strap 4 and the second ear strap 5 more convenient, and the two pressure strips 3 are respectively provided with the first ear strap 4 and the second ear strap 5, the two ends of the first ear strap 4 are respectively bonded to the upper and lower pressure strips 3 on the left side, and the two ends of the second ear strap 5 are respectively bonded to the upper and lower pressure strips 3 on the right side, and the arrangement of the sliding buckle 6 can best control the length of the first ear strap 4 and the second ear strap 5, so as to adapt to different face sizes, the first ear strap 4 and the second ear strap 5 are slidably connected with the sliding buckle 6, and the front of the main body 1 is fixedly connected with a connecting mouth 7, and the connecting mouth A sealing gasket 9 is provided inside 7, and a mounting sleeve 10 is connected to the external thread of the connecting nozzle 7. An external thread 8 is provided on the outside of the connecting nozzle 7. An internal thread 11 is provided on the inner wall of the mounting sleeve 10, and the mounting sleeve 10 is threadedly connected to the outside of the connecting nozzle 7 through the internal thread 11 and the external thread 8. The setting of the mounting sleeve 10 can make installation more convenient and simpler to operate. A filter plate 12 is provided inside the mounting sleeve 10, and a meltblown cloth 19 is fixedly installed inside the filter plate 12. An adhesive tape 13 is bonded to the back of the sealing ring 2, and a strip 14 is bonded to the outside of the adhesive tape 13. The adhesive tape 13 and the strip 14 are symmetrically installed on the left and right. The strip 14 has the same size as the adhesive tape 13, and there is a certain gap between the strip 14 and the adhesive tape 13. The setting of the adhesive tape 13 can make the mask fit more closely to the face, and the setting of the strip 14 prevents premature debonding and failure.

[0027] When using the medical mask, first tear off the sticker 14 from the adhesive tape 13, then hang the first ear strap 4 and the second ear strap 5 on the left and right ears, and adjust the length through the slide buckle 6 according to the size of the face for easy fitting and wearing. Then the adhesive tape 13 can be bonded to the face to eliminate the gap between the mask and the face for comprehensive protection. When the meltblown cloth 19 fails, the filter plate 12 can be removed and replaced with a new one, which greatly reduces the waste of the meltblown cloth 19 and is very convenient and easy to operate.

[0028] Embodiment 2:

[0029] See also Figures 1 to 6The utility model provides a technical solution: a medical mask, a deodorizer 15 is fixedly installed on the surface of a main body 1, a convex edge 16 is fixedly connected to the front of the deodorizer 15, and an air hole 17 is opened at the bottom of the deodorizer 15. The deodorizer 15 is symmetrically arranged on the left and right, the size of the convex edge 16 is larger than the size of the deodorizer 15, the convex edge 16 is annular and a filter is arranged inside, one end of the air hole 17 is located on the inner wall of the main body 1, and an activated carbon rod 18 is arranged inside the deodorizer 15. The deodorizer 15 and the internal activated carbon rod 18 can eliminate the odor in the outside air and ensure the comfort of medical staff when working.

[0030] When using the medical mask, if there is an odor in the external air, the odor will pass through the filter mesh in the convex edge 16 to initially filter out foreign particles, and then enter the deodorizer 15, and then be adsorbed by the activated carbon rod 18, and then the odor-removing gas is input through the air hole 17, which effectively reduces the odor gas, making it more comfortable and assured for medical staff to use.
