Description

Technical Field

[0001] The utility model relates to the field of personal protective equipment, in particular to a slip-proof, high-efficiency, low-resistance and antibacterial mask. Background Art

[0002] N95 masks are highly effective protective masks widely used in medical, industrial and daily protection. The filtration efficiency of N95 masks reaches over 95%, and they are highly praised for their excellent filtration performance and comfortable design. The main purpose of N95 masks is to filter particulate matter in the air and effectively prevent the invasion of bacteria, viruses and other harmful substances. Its structure is usually composed of three or more layers of materials: the outer layer is made of waterproof polypropylene non-woven fabric to block droplets and liquids; the middle layer is the key melt-blown polypropylene cloth, which efficiently filters tiny particles and pathogens through electrostatic adsorption and fine fiber structure; the inner layer is made of soft polypropylene non-woven fabric, which directly contacts the skin, has good breathability and comfort, and absorbs moisture generated by breathing to keep dry.

[0003] Most N95 masks and other protective masks on the market are fixed with two elastic straps, one on the top and one on the neck. The purpose of this design is to ensure that the mask fits the face tightly and improves the protective effect. Through this method of fixing the two elastic straps, the risk of air leakage from the edge of the mask can be effectively reduced when the mask is worn, thereby providing better sealing and protective effects. However, this design also exposes some problems in actual use. First, the upper fixing strap is easy to slide down, causing the mask to not be kept in the ideal position. This causes the wearer's ears to be strangled and cause discomfort; in addition, due to the displacement of the elastic band, there is a risk of reduced sealing between the edge of the mask and the face, and it is easy for air to be directly inhaled from the edge of the mask, exposing the wearer to a higher risk of infection or contamination.

[0004] Therefore, although the design of the upper and lower elastic bands provides better sealing in theory, in actual use, the slipping defect of this elastic fixing band design may have a negative impact on the overall protective performance of the mask, and the existing mask fixed with two upper and lower elastic bands needs to be further optimized and improved. Utility Model Content

[0005] The utility model aims to provide a high-efficiency, low-resistance and antibacterial mask which is anti-slip.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following scheme: a non-slip, high-efficiency, low-resistance and antibacterial mask, comprising a ship-shaped mask body and ear straps for wearing the mask body, wherein the mask body comprises an inner layer of non-woven fabric, a double layer of filter cotton, a double layer of melt-blown fabric and an outer layer of non-woven fabric stacked together from the inside to the outside, and this multi-layer structure not only improves the filtering effect, but also maintains good air permeability. The ear straps include an upper ear strap connected to the upper side of the mask body for surrounding the wearer's head above the ear and a lower ear strap connected to the lower side of the mask body for surrounding the wearer's neck, and the two free ends of the upper ear strap and the lower ear strap are respectively connected together to form a complete ring and connected to the left and right sides of the mask body, so that the mask can be fixed more stably, preventing the mask from moving during wearing, and improving the sealing and comfort. A nose shaping strip is provided on the upper surface of the outer non-woven fabric of the mask body to help the mask body fit the bridge of the nose better and enhance the sealing performance; a nose decompression strip is provided on the upper surface of the inner non-woven fabric of the mask body to reduce the pressure on the bridge of the nose and improve the wearing comfort; an adjusting piece that can adjust the length of the upper ear band and ensure that the mask fits the face closely is detachably provided on the upper ear band; and an anti-slip portion is provided on the adjusting piece that can prevent the upper ear band from sliding down, reduce the discomfort of the ears and avoid the reduction of sealing performance.

[0007] As a further solution of the utility model, the adjustment member includes a sheet-shaped fixing plate, on which notches are arranged at intervals, and the notches are open on one side facing the edge of the fixing plate, and elastic clips are movably arranged in the two notches, and a clamping gap is provided between the elastic clip and one of the inner walls of the notches, and an elastic part capable of keeping the elastic clip extending toward the clamping gap is provided at one end of the elastic clip away from the clamping gap, and the end of the elastic part away from the elastic clip is connected to the fixing plate, and a limiting groove is provided on the top of the fixing plate, and the upper ear band passes through the two clamping gaps, and the upper ear band between the two clamping gaps bypasses the top of the fixing plate and is embedded in the limiting groove, and the anti-slip part is arranged at the bottom of the fixing plate. The upper ear band passes through the clamping gap, and the elastic extrusion and clamping action of the elastic clip prevents the adjusted upper ear band from sliding in the clamping gap, thereby maintaining the stability of the adjusted upper ear band.

[0008] As a further solution of the utility model, the anti-slip portion includes a connecting arm bent downward from one edge of a fixed plate, an anti-slip plate is provided under the fixed plate, one edge of the anti-slip plate is connected to the connecting arm, and comb teeth are provided on the side of the anti-slip plate away from the connecting arm, and the comb teeth can be inserted into the hair to prevent the upper ear band from sliding downward from the back of the head.

[0009] As a further solution of the utility model, the clamping gap is in the shape of an outwardly inclined groove, and the elastic clip is provided with at least one latching tooth on the inclined outer wall facing the clamping gap, and the latching tooth extends along the length direction of the clamping gap side, ensuring that the upper ear band can be firmly fixed in the clamping gap when subjected to force and will not slide easily.

[0010] As a preferred solution of the utility model, the elastic part is a "V"-shaped elastic connecting strip connected between the elastic clip and the inner wall of the groove, which provides good elasticity and stability, ensuring that the adjustment member can be smoothly operated and remain fixed when adjusting the length of the ear strap.

[0011] As a preferred solution of the utility model, the top surface of the fixing plate located between the two notches is provided with a convex beam protruding upward, and the limiting groove is arranged on the convex beam, ensuring that the upper ear band can be stably fixed in the groove after adjusting the length and is not easy to slip off the fixing plate.

[0012] As a preferred solution of the utility model, upwardly protruding toggle portions are respectively provided on the top surfaces of the elastic clips to facilitate the contraction of the elastic clips so as to expand the clamping gap and allow the upper ear band to be pulled in the clamping gap.

[0013] As a further solution of the utility model, an anti-slip rubber pad is provided on the bottom surface of the anti-slip plate.

[0014] As a preferred solution of the utility model, the anti-skid rubber pad is densely covered with anti-skid rubber particles, and the anti-skid rubber pad and the anti-skid rubber particles can further increase the friction force to prevent the fixing plate from sliding on the back of the head.

[0015] As a preferred solution of the utility model, the elastic clip, the connecting strip, the connecting arm, the anti-slip plate, and the comb teeth are integrally injection molded with the fixing plate. Integral injection molding improves the stability and durability of the entire adjustment member structure, reduces assembly procedures and possible risks of falling off, and enhances service life and reliability.

[0016] In summary, the utility model has the following beneficial effects compared with the prior art: the utility model ensures excellent filtering performance and air permeability through the multi-layer structure of inner non-woven fabric, double-layer filter cotton, double-layer meltblown fabric and outer non-woven fabric. The sealing and wearing comfort of the mask are improved by setting the nose bridge shaping strip and the pressure relief strip. Among them, the ear strap adopts an upper and lower fixing method, and is provided with an adjustable length adjustment member and an anti-slip portion to prevent the upper ear strap from gradually sliding down during wearing, and reduce the discomfort caused by ear compression. The fixing plate, the slot, the elastic clip and the V-shaped elastic connecting strip in the adjustment member structure provide a stable upper ear strap adjustment and locking effect through the clamping teeth and the clamping gap. The anti-slip plate and comb tooth design further prevent the upper stop ear strap from sliding and keep the mask stable. The overall one-piece injection molding enhances the structural stability and durability. The above schemes are combined to effectively solve the slipping defects of the existing elastic fixing belt design and the negative impact on the overall protective performance of the mask, and achieve better sealing, comfort and protective effect of the mask.

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods: Figures 1 to 5The illustrated embodiment of a non-slip, high-efficiency, low-resistance and antibacterial mask comprises a ship-shaped mask body 1 and ear straps 2 for wearing the mask body 1, wherein the mask body 1 comprises an inner layer of non-woven fabric, a double-layer filter cotton, a double-layer meltblown fabric and an outer layer of non-woven fabric stacked together from the inside to the outside, and the ear straps 2 comprise an upper ear strap 21 connected to the upper side of the mask body 1 for wrapping around the wearer's head and above the ear, and a lower ear strap 22 connected to the lower side of the mask body 1 for wrapping around the wearer's neck, the two free ends of the upper ear strap 21 and the two free ends of the lower ear strap 22 are respectively connected together to form a complete circle, and are connected to the left and right sides of the mask body 1, a nose bridge shaping strip 3 is provided on the upper side surface of the outer layer of non-woven fabric of the mask body 1, a nose bridge decompression strip 4 is provided on the upper side surface of the inner layer of non-woven fabric of the mask body 1, and an adjusting member 5 capable of adjusting the length of the upper ear strap 21 is detachably provided on the upper ear strap 21, and an anti-slip portion 6 capable of preventing the upper ear strap 21 from sliding down is provided on the adjusting member 5. The multi-layer structure of the mask body 1 (including inner non-woven fabric, double-layer filter cotton, double-layer melt-blown fabric and outer non-woven fabric) ensures excellent filtering performance and air permeability. The melt-blown fabric is made of 32 parts of polypropylene, 15 parts of polytetrafluoroethylene, 17 parts of modified tourmaline, 1 part of hindered amine light stabilizer, 4 parts of silicon waterproofing agent, 6 parts of erucic acid amide, 0.5 parts of 1010 antioxidant, 2 parts of polyethylene wax, 1 part of stearate, 2 parts of ethylene bis stearamide EBS, and 0.1-0.5 parts of silver ions. Among them, polypropylene is the base material, polytetrafluoroethylene powder and modified tourmaline are electret adsorption materials, hindered amine light stabilizer is hindered amine electron capture agent, and the electret masterbatch made of silicon waterproofing agent, erucic acid amide, and antioxidant as additives is made as raw materials to achieve the function of high efficiency, low resistance and antibacterial. The adjusting member 5 and the anti-slip portion 6 that can adjust the length of the upper ear band 21 can prevent the upper ear band 21 from gradually sliding downward during wearing, causing the ear to be compressed and feel uncomfortable.

[0029] Specifically, if Figures 1 to 8As shown, the adjusting member 5 includes a fixing plate 51, which is in the shape of a long strip, and is provided with slots 52 at intervals on the fixing plate 51. The slots 52 are open on one side facing the edge of the fixing plate 51. Elastic clips 53 are movably provided in the two slots 52, respectively. A clamping gap 54 is provided between the elastic clip 53 and the inner wall of one side of the slot 52. An elastic part 7 capable of keeping the elastic clip 53 extending toward the clamping gap 54 is provided at one end of the elastic clip 53 away from the clamping gap 54. The elastic part 7 is connected to the elastic clip. There is a "V"-shaped elastic connecting strip 71 between 53 and the inner wall of the notch 52 where it is located, and an upwardly protruding toggle portion 58 is provided on the top surface of the elastic clip 53, and an upwardly protruding convex beam 57 is provided on the top surface of the fixing plate 51 between the two notches 52, and an upwardly recessed limiting groove 55 is provided on the top of the convex beam 57. The upper ear band 21 passes through the two clamping gaps 54, and the upper ear band 21 between the two clamping gaps 54 bypasses the top of the fixing plate 51 and is embedded in the limiting groove 55, and the anti-slip portion 6 is arranged at the bottom of the fixing plate 51. It should be noted that in order to further prevent the upper ear band 21 from sliding in the clamping gap 54 passed through, the clamping gap 54 is in the shape of an outwardly inclined oblique groove, and a plurality of latch teeth 56 are provided on the inclined outer wall of the elastic clip 53 facing the clamping gap 54, and the latch teeth 56 extend along the length direction of the clamping gap 54. When wearing a mask, if Figure 5 As shown in , after putting the lower ear strap 22 on the neck, buckle the mask body 1 on the nose and mouth, and then put the upper ear strap 21 on the back of the head from the top of the head. When the length of the ear strap 2 needs to be adjusted, pinch the toggle part 58 toward the center with one hand. At this time, the elastic connecting strip 71 is compressed and deformed, and the two elastic clips 53 retract in the opposite direction to the clamping gap 54. With the other hand, pull up the upper ear strap 21 that bypasses the top of the fixing plate 51 and is embedded in the limiting groove 55 until the tightness of the upper ear strap 21 below the fixing plate 51 reaches the appropriate length, and then release the toggle part 58. The elastic clip 53 is reset and pushed forward by the elastic connecting strip 71 in the missing groove 52, so that the clamping gap 54 is reduced. In this way, the upper ear strap 21 will be clamped in the missing groove 52, and the adjusted length of the upper ear strap 21 can be locked by the latch 56 on the elastic clip 53.

[0030] In addition, in order to prevent the fixing plate 51 from sliding down along the wearer's hair, Figures 6 to 8As shown, the anti-slip portion 6 includes a connecting arm 61 bent downward from one side edge of the fixing plate 51, an anti-slip plate 62 is provided below the fixing plate 51, and one side edge of the anti-slip plate 62 is connected to the connecting arm 61, and a comb tooth 63 is provided on the side of the anti-slip plate 62 away from the connecting arm 61, and the comb tooth 63 can be inserted into the wearer's hair to ensure that the fixing plate 51 will not slip off during the wearing process, and further ensure that the upper ear band 21 will not slip off together and press on the top of the wearer's ear. When the wearer wears a safety protection device such as a hat or a helmet on his head, the comb tooth 63 cannot play a role, so an anti-slip rubber pad 60 is provided on the bottom surface of the anti-slip plate 62, and the anti-slip rubber pad 60 is densely covered with anti-slip rubber particles 64. When the bottom surface of the anti-slip plate 62 contacts the surface of the hat or helmet, the anti-slip rubber pad 60 and the anti-slip rubber particles 64 can achieve friction with the surface of the hat or helmet to prevent the fixing plate 51 from sliding down.

[0031] Finally, the elastic clip 53, the elastic connecting strip 71, the connecting arm 61, the anti-slip plate 62 and the comb teeth 63 in this embodiment are integrally injection molded with the fixing plate 51. In this way, when the user changes the mask, the upper ear band 21 of the used mask body 1 can be removed from the clamping gap 54 of the adjusting member 5, and then the adjusting member 5 can be installed on the ear band of the new mask for replacement and reuse.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
