TECHNICAL FIELD
[0001] The present application relates to the field of health masks, in particular to a health mask for human protection. BACKGROUND
[0002] In medical care, daily travel, industrial production and other scenarios, the health mask for human protection is a core protection tool for blocking droplet transmission and filtering harmful particulate matter, which needs to meet the requirements of long-time wearing comfort, protection fit and no gap.
[0003] The existing technology mask adopts two elastic ear hanging ropes which are directly fixed on the ears, and the mask body and the fixed structure are designed in an integrated manner, which cannot adjust the angle of the mask according to the use scenario, resulting in loose fit.
[0004] Therefore, it is necessary to provide a health mask for human protection to solve the above technical problems. SUMMARY
[0005] Based on the above description, the present application provides a health mask for human protection to solve the problem that the existing technology cannot adjust the angle of the mask according to the use scenario, resulting in loose fit.
[0006] The technical solution of the present application to solve the above technical problems is as follows: a health mask for human protection, comprising a rope body restraint member for fixing on the head of a user, a chin fixing member, an angle adjusting member and a mask member, the chin fixing member is connected to the rope body restraint member and is fixed at the chin position of the user to form a support structure with the rope body restraint member; the angle adjusting member is connected to the chin fixing member; the mask member is connected to the angle adjusting member to adjust the angle under the driving of the angle adjusting member.
[0007] Preferably, the rope body restraint member and the chin fixing member form a support structure, the chin fixing member is connected to the rope body restraint member and is fixed at the chin position of the user, which can effectively share the tension of the rope body restraint member on the ears, so that the mask is more stably fitted on the face. For example, in long-time high-intensity work, the mask of medical staff will not be easily displaced by frequent walking, bending and other actions, and always maintains effective coverage of the mouth and nose, greatly improving the stability of wearing.
[0008] Secondly, the chin fixing member shares part of the tension, reducing the force borne by the ears and effectively relieving the pressure on the ears. For example, students wear the mask all day in school, after using the mask, the discomfort of the students' ears is significantly reduced, and they can focus more on learning, improving the comfort of wearing.
[0009] Finally, the angle adjusting member is connected to the chin fixing member, and the mask member is connected to the angle adjusting member. Users can adjust the angle of the mask member through the angle adjusting member according to their own facial features. For example, for people with thin faces and high cheekbones, the mask member can be adjusted upward to better fit the cheekbone area. For people with round faces, the angle can be adjusted downward to ensure that the mask closely fits the face, thereby improving the adaptability of the mask to different face shapes.
[0010] Further, the rope binding member includes a first binding rope, one end of the first binding rope is connected with a first adjusting buckle, and the first adjusting buckle is connected to the middle part of the first binding rope to form a first ear buckle.
[0011] Preferably, one end of the first binding rope is connected with a first adjusting buckle, and the first adjusting buckle is connected to the middle part of the first binding rope to form a first ear buckle. Users can easily change the size of the first ear buckle by operating the first adjusting buckle according to their own head circumference. For example, children with small head circumferences can adjust the first ear buckle to be smaller to better fit the head and reduce ear pressure. Adults with large head circumferences can adjust the buckle to be larger to ensure that the mask can be comfortably and stably worn, greatly improving the convenience and individuality of wearing.
[0012] Further, the rope binding member includes a second binding rope, one end of the second binding rope is connected with a second adjusting buckle, and the second adjusting buckle is connected to the middle part of the second binding rope to form a second ear buckle.
[0013] Preferably, the second binding rope has one end connected with a second adjusting buckle, and the second adjusting buckle is connected to the middle part of the second binding rope to form a second ear buckle. Users can flexibly adjust the size of the second ear buckle by operating the second adjusting buckle according to their own head circumference. For example, women with small head circumferences can adjust the second ear buckle to be smaller to make the mask more closely fit the head and avoid gaps. Men with large head circumferences can adjust the buckle to be larger to ensure that the mask can be comfortably worn on the face without feeling oppressed due to being too tight, thereby greatly improving the adaptability of the mask to users with different head circumferences.
[0014] Further, the rope binding member includes a rear auxiliary rope connected at one end to the first ear buckle and at the other end to the second ear buckle, and the rear auxiliary rope is used to abut against the back of the head of the user.
[0015] Preferably, one end of the rear auxiliary rope is connected with the first ear loop, and the other end is connected with the second ear loop, and is used for abutting against the back of the user's head. Such a design forms a full- range fixing system, and the rear auxiliary rope gives the mask additional support from the back of the head, and cooperates with the ear loop to stably fix the mask on the face. For example, medical staff needs to make rapid and large- scale body movements when rescuing patients in an emergency, and after using the mask, the rear auxiliary rope can effectively prevent the mask from slipping or shifting, and ensure that reliable protection is always provided for the medical staff.
[0016] Further, the chin fixing member comprises a chin cover sleeve with a middle part being deep and two side parts being shallow, the first binding rope is connected to one side of the chin cover sleeve, and the second binding rope is connected to the other side of the chin cover sleeve.
[0017] Preferably, the shape of the chin varies from person to person, and there are relatively round chins and relatively sharp chins. The chin fixing member adopts the design of the chin cover sleeve with the middle part being deep and the two side parts being shallow, which can better adapt to chins of different shapes. The deep middle part can accommodate various types of chins and provide sufficient accommodation space for the chin to avoid a sense of oppression due to insufficient space; the shallow two side parts can closely fit the contours of the two sides of the chin, so that the mask and the chin form a good sealing effect. For example, for users with relatively round chins, the design of the deep middle part will not make the chin feel cramped; and for users with relatively sharp chins, the close-fitting design of the shallow two side parts can ensure that the mask is stably attached to the chin without gaps, effectively preventing external pollutants from entering the inside of the mask from the chin part.
[0018] Further, the angle adjusting member comprises side plates connected to the chin cover sleeve, two side plates are provided, rotating shafts are connected to the two side plates, a rotating cylinder is rotatably connected between the two rotating shafts, the rotating cylinder is connected to the rotating shafts, and the mask member is connected to the rotating cylinder.
[0019] Preferably, the shape of the chin varies from person to person, and there are relatively round chins and relatively sharp chins. The chin fixing member adopts the design of the chin cover sleeve with the middle part being deep and the two side parts being shallow, which can better adapt to chins of different shapes. The deep middle part can accommodate various types of chins and provide sufficient accommodation space for the chin to avoid a sense of oppression due to insufficient space; the shallow two side parts can closely fit the contours of the two sides of the chin, so that the mask and the chin form a good sealing effect. For example, for users with relatively round chins, the design of the deep middle part will not make the chin feel cramped; and for users with relatively sharp chins, the close-fitting design of the shallow two side parts can ensure that the mask is stably attached to the chin without gaps, effectively preventing external pollutants from entering the inside of the mask from the chin part.
[0020] Further, the limiting piece includes a limiting groove arranged on the rotating cylinder and a sliding seat connected to the chin cover, and the sliding seat is slidingly connected with a sliding block, and the sliding block is in abutment with the limiting groove to limit the rotating cylinder.
[0021] Preferably, during use of the mask, the chin cover needs to be adjusted in angle around the rotating shaft to adapt to the chin shape and activity state of different users. However, if there is no effective limiting measure, the chin cover may be accidentally rotated in the action of the user without intention (such as turning head, large amplitude movement of facial muscles when speaking), which causes the fitting degree of the mask to the face to be reduced, affecting the protection effect. In the limiting piece of the mask, the rotating shaft is provided with a limiting groove, the chin cover is connected with a sliding seat, and the sliding seat is slidingly connected with a sliding block, and the sliding block is in abutment with the limiting groove. When the user adjusts the chin cover to the appropriate angle, the sliding block will be embedded in the corresponding limiting groove, which plays a role in precise positioning, effectively preventing the chin cover from being accidentally rotated during use, and ensuring that the mask always maintains the best wearing angle. For example, during the tense operation of medical staff, the face will have various subtle movements, and the limiting piece can ensure that the chin cover will not be deviated due to these movements, and maintain the stable wearing of the mask.
[0022] Further, the limiting piece includes a spring connected to the sliding seat, and the spring is connected with the sliding block.
[0023] Preferably, the spring is connected between the sliding seat and the sliding block, which provides the sliding block with elastic force. When the user adjusts the angle of the chin cover, the sliding block can be more accurately embedded in the limiting groove on the rotating shaft under the elastic constraint of the spring. Compared with the limiting structure without the assistance of the spring, the presence of the spring enables the sliding block to slowly and accurately fall into the groove by the elastic buffer of the spring when approaching the limiting groove, realizing more fine angle adjustment. For example, for users who have extremely high requirements for the comfort of wearing the mask, they can adjust the sliding block to the appropriate limiting groove by slightly rotating the chin cover and using the elastic feedback of the spring, so as to find the most suitable angle of the chin cover for themselves, and improve the fitting degree and comfort of wearing.
[0024] Further, the sliding block is connected with a pushing block.
[0025] Preferably, after connecting the sliding block with the toggle block, the user does not need to directly operate the relatively small sliding block with fingers. The toggle block usually has a larger contact area and a more ergonomic shape, which is convenient for the user to grasp and apply force. When adjusting the angle of the chin cover, the user only needs to gently toggle the toggle block to drive the sliding block to slide on the sliding seat, so that it cooperates with or separates from the limiting groove on the rotating shaft, realizing accurate adjustment of the angle. For example, when walking quickly outdoors or exercising, the user can quickly adjust the angle of the mask by toggling the toggle block with one hand, without stopping or performing complex operations, greatly improving the convenience and efficiency of operation.
[0026] Further, the mask piece includes a metal support connected to the angle adjusting piece and a clamping frame clamped on the metal support, and the mask is connected to the clamping frame.
[0027] Preferably, the metal support is connected to the angle adjusting piece, providing a solid foundation for the entire mask piece. The metal material has high strength and rigidity, and can withstand various external forces during use of the mask. The clamping frame is connected to the metal support by clamping, which is convenient and firm. The clamping structure can provide a large connection force to ensure that the clamping frame is stable on the metal support, and also facilitates replacement of the mask.
[0028] Compared with the prior art, the technical scheme of the present application has the following beneficial technical effects:
[0029] The angle adjusting piece is connected to the chin fixing piece, and the mask piece is connected to the angle adjusting piece. The user can adjust the angle of the mask piece through the angle adjusting piece according to the characteristics of his own face. For example, for people with thin faces and high cheekbones, the mask piece can be adjusted upward to better fit the cheekbone area; for people with round faces, the angle can be adjusted downward appropriately to ensure that the mask is tightly fitted to the face, improving the adaptability of the mask to different face shapes. The problem that the prior art cannot adjust the angle of the mask according to the use scenario, resulting in poor fitting, is solved. BRIEF DESCRIPTION OF DRAWINGS
