Description

Support frame and mask containing support frame

The invention relates to a support structure; in particular, it refers to a support frame and a mask containing the support frame.

A mask is a common medical and health product on the market. Its function is that when the user wears a mask, the mask can filter suspended particles or bacteria and viruses in the air, and prevent suspended particles or bacteria and viruses from entering the user's respiratory organs. In the human body, it can prevent users from having symptoms of colds, infectious diseases or hay fever. Please refer to FIG. 1, a known mask 1 has a filter layer 2 and two straps 3. The two straps 3 are fixed to one side edge of the filter layer 2 respectively. The filter layer 2 is usually formed by pressing multiple pieces of cloth with different filtering functions, and has a plurality of pleated portions in the middle section, and the pleated portions can increase the surface area of the filter layer. When the user wears the mask 1, the two straps 3 are respectively hung on one ear of the user, and the upper and lower ends of the filter layer 2 respectively touch the nose and chin of the user. The folds of the filter layer 2 After being pulled by the user, it can be transformed from the original flat state into the three-dimensional state as shown in FIG. 1, so that there is a distance D1 between the user's mouth and the inner surface of the mask, as shown in FIG.

However, the filter layer of the mask is a soft cloth. When the user breathes, the inner surface of the mask 1 easily touches the user's mouth and nose during inhalation, and cannot maintain the aforementioned distance D1 from the user's mouth. If the user has oral and nasal secretions or make-up, it will stick to the inner face of the mask, and the mask with these sticky substances cannot be reused, causing the user to frequently discard the used mask , Use a new mask. Therefore, a large number of discarded masks will be produced in the long run, and the garbage is not properly disposed of and discarded everywhere, which may increase the burden of environmental hygiene. In addition, if you need to wear a mask to speak due to occupational factors (such as a teacher's lecture), it is easy for the mask to directly touch the mouth, so that the saliva soaks the mask. Because of the phenomenon of surface tension, the mask loses its hydrophobicity and loses its protective ability. Therefore, it is necessary to resolve the aforementioned situation.

In view of this, the object of the present invention is to provide a support frame and a mask including the support frame, the mask including the support frame can prevent the user's mouth and nose secretions or cosmetics from sticking to the inner surface of the mask.

In order to achieve the above-mentioned object, the support frame provided by the present invention is used to transform an object from a flat state into a three-dimensional state. It includes a bent support portion, the support portion has a long axis, and the support portion The two ends of the long axis are respectively connected with a fixing part, and the two fixing parts are connected with the object.

The present invention also provides a mask which is in a three-dimensional state after being deformed. The mask includes a mask body and the aforementioned support frame. The mask body includes at least one filter layer and a plurality of straps, the filter layer is in a plane state, the filter layer has a plurality of pleated parts, and at least one of the straps is fixed to a first of the filter layer At the side edge, at least another of the ties is fixed to a second side edge of the filter layer; the first side edge and the second side edge are two opposite sides of the filter layer. The two fixing parts of the support frame are connected to at least one of the fold parts, so that the filter layer is transformed from a flat state into a three-dimensional state. Thereby, when the user puts on the mask, with the support of the support frame, there is a distance between the mask body and the mouth or nose of the user.

The effect of the present invention is that the support frame can maintain the aforementioned distance between the mask body and the user’s mouth or nose, preventing the user’s mouth and nose secretions or makeup from sticking to the inner surface of the mask body. The masks without sticky substances can be reused after simple disinfection. Secondly, the distance between the inner surface of the mask body of the present invention and the mouth and nose of the user is greater than the distance between the inner surface of the conventional mask and the mouth and nose of the user, which reduces the moisture exhaled by the user directly contacting the filter layer of the mask. The foregoing situation effectively prolongs the service life of the mask and reduces the frequency of users replacing old masks with new ones. Furthermore, if every mask user can reduce the frequency of replacing the old with the new, it will help reduce personal pollution to the environment, which is quite an environmentally friendly behavior. However, there are always times when the filter layer of the mask can no longer perform its functions, and we must replace the old with the new. At this time, the support frame can be detached from the old mask originally combined, and after simple cleaning and disinfection, it can be reinstalled on the new mask for use. Therefore, the support frame of the present invention can not only prolong the service life of the combined mask, but also the support frame itself can be reused to achieve environmental protection effects.

In order to explain the present invention more clearly, preferred embodiments are described in detail in conjunction with the drawings as follows. Please refer to FIG. 3, which is a supporting frame 100 of a preferred embodiment of the present invention. The supporting frame 100 is used to transform an object from a flat state into a three-dimensional state.

The supporting frame 100 includes a supporting portion 10 and two fixing portions 20. Wherein, the supporting portion 10 is bent and has a first surface 10a and a second surface 10b opposite to each other. The supporting portion 10 has a top edge 11 on the first surface 10a, and the top edge 11 is a protrusion of the supporting portion 10 on the first surface 10a. The supporting portion 10 has a long axis X1 and a short axis X2. Wherein, the short axis X2 is perpendicular to the long axis X1 and perpendicular to the direction from the first surface 10a to the second surface 10b. The supporting portion 10 includes a middle section 12 and two side sections 14. The middle section 12 is located between the two side sections 14, and the top edge 11 is located at the middle section 12. The length of the middle section 12 on the short axis X2 is greater than the length of each of the side sections 14 on the short axis X2.

The supporting portion 10 has a plurality of through holes 16. The through holes 16 are arranged along the longitudinal axis X1 of the support portion 10 and penetrate the support portion 10 on the first surface 10a and the second surface 10b. In this embodiment, the through holes 16 have a plurality of first through holes 161 and a plurality of second through holes 162. The size of the first through holes 161 is larger than the size of the second through holes 162, and they are arranged at equal intervals on the upper part of the middle section 12 of the supporting portion 10; the second through holes 162 are arranged at equal intervals in the middle section 12 The lower part and the two side sections 14. However, the shape and size of the through holes are not limited to those shown in the drawings.

The two fixing portions 20 are respectively connected to the two ends of the supporting portion 10 in the longitudinal axis X1. More specifically, the two fixing portions 20 are respectively connected to the side edge of the side section 14 away from the middle section 12. In this embodiment, the two fixing portions 20 and the supporting portion 10 are integrally formed. Each of the fixing portions 20 is used to connect the object, and has a clamping groove 22. The clamping groove 22 has two groove walls 222, and the clamping groove 22 has a clamping direction H. The clamping direction H is the opening direction of the two groove walls 222 and is perpendicular to the longitudinal axis X1 of the supporting portion 10 . When the two fixing parts 20 are connected to the object, the two groove walls 222 pinch a part of the object, so that the support frame 100 is detachably fixed on the object; and the top edge 11 will abut On the object, the object is transformed into a three-dimensional state and maintained in this state. It is worth mentioning that the connection between each fixing portion 20 and the supporting portion 10 has a notch 24, and the purpose of the cutout 24 is that each fixing portion 20 can be slightly twisted and deformed relative to the supporting portion 10. When a part of the object is clamped by the two groove walls 222 of each clamping groove 22, the contact relationship between the supporting portion 10 and the object will not be affected.

As shown in FIGS. 4 and 5, the aforementioned support frame 100 is combined with a mask body 200 to form the mask of the present invention, and the mask body 200 is in a solid state after being deformed. The mask body 200 includes at least one filter layer 210 and a plurality of straps 220. Wherein, the at least one filter layer 210 is in a planar state, it has a plurality of folds 212 and a first side edge 210a and a second side edge 210b located on two opposite sides, at least one of the ties 220 It is fixed to the first side edge 210a, and at least another one of the straps 220 is fixed to the second side edge 210b. In this embodiment, the number of filter layers is one and the number of straps is two. When the support frame 100 is connected to the filter layer 210, the support frame 100 clamps at least one of the folds 212 with the two groove walls 222 of each clamping groove 22, so that the support frame 100 is detachable It is fixed on the filter layer 210 off the ground. In this embodiment, the two clamping grooves 22 are connected to the same folding portion 212. The top edge 11 of the supporting portion 10 abuts against the filter layer 210, so that the filter layer 210 is transformed from a flat state into a three-dimensional state.

1 and FIG. 2, FIG. 1 is a schematic diagram of the left side of a user wearing a conventional mask 1, and the mask 1 has been partially cut for illustration. The conventional mask 1 can be pulled by the user to make the folds of the filter layer 2 unfold from the original flat state, and the filter layer 2 can be deformed into a three-dimensional state as shown in FIG. 1. Fig. 2 is a bottom view of the user wearing a mask, and in order to clearly show the relationship between the inner surface of the filter layer 2 and the user’s nose and mouth, the mask 1 has been partially cut for illustration. The aforementioned three-dimensional state makes a distance D1 between the user's mouth and the inner surface of the filter layer 2. However, the filter layer 210 of the mask 1 is a soft cloth, so the inner surface of the filter layer 2 is easy for the user to inhale. It touches the user’s mouth and nose and cannot maintain the aforementioned distance D1 with the user’s mouth. If the user has oral and nasal secretions or make-up, it will stick to the inner surface of the filter layer 2, and the mask with these stickies cannot be reused. In addition, the water vapor exhaled by the user can easily wet the filter layer 210. In addition to causing poor user experience, the water vapor can easily destroy the filtering effect of the filter layer 2. The foregoing situation causes users to frequently discard used masks and use new masks.

In contrast, the mask of the present invention has a detachable support frame 100 (refer to Figures 6 and 7, which correspond to Figures 1 and 2 respectively), wherein the filter layer 210 of the mask body 200 is The support frame 100 protrudes in a direction away from the nose and mouth of the user, so that the upper part of the filter layer 210 and the nose of the user can maintain a distance D2, and the lower part of the filter layer 210 of the mask body 200 is with the user The mouth can also maintain a distance D3, and the distance D2 and the distance D3 are both greater than the distance D1, so that the space formed inside the filter layer 210 is larger than the space formed inside the filter layer 2. On the other hand, the purpose of the length of the middle section 12 of the supporting portion 10 in the short axis X2 is greater than the length of each side section 14 in the short axis X2 is that the middle section 12 of the supporting portion 10 faces the mouth and nose of the user. It is necessary to maintain a good fixing effect, so a larger length is required, and the two side sections 14 are only auxiliary supports. The through holes 16 can keep the inside of the mask and the outside air circulating. Thereby, when the user wears the mask with the support frame 100, the inside of the mask can be kept comfortable and dry, moisture is not easy to damage the hydrophobicity of the filter layer, and the user is provided with good wearing comfort. For example, for some professional users who need to wear a mask to speak, such as a teacher in a class, the support frame will not allow the mask to directly touch the user's mouth, and maintain the hydrophobicity and protection of the mask.

The mask of the present invention can prevent the user’s mouth and nose secretions and make-up from contacting the inner surface of the filter layer 210. In addition to keeping the inner surface of the filter layer 210 dry and clean, medical reports indicate that the general mask does not touch the inner surface of the filter layer 210. In the case of food, dirt or water, it can be reused after simple disinfection and cleaning, which effectively prolongs the life of the mask and reduces the frequency of users replacing old masks with new ones. Furthermore, if every mask user can reduce the frequency of replacing the old with the new, it will help reduce personal pollution to the environment, which is quite an environmentally friendly behavior. Secondly, the material of the support frame of the present invention is a waterproof material. When the filter layer of the mask can no longer perform its function, we must replace the old with a new one. At this time, the support frame can be detached from the old mask that was originally combined, and after simple cleaning and disinfection, it can be reinstalled on the new mask for use to achieve environmental protection. In summary, the support frame of the present invention can extend the life of the mask to which it is combined, and the support frame itself can also be reused, which helps reduce waste generation.

The above are only the preferred and feasible embodiments of the present invention. Any equivalent changes made by applying the specification of the present invention and the scope of the patent application should be included in the patent scope of the present invention.
