Description

Technical Field

[0001] This utility model relates to a respirator made of densely folded PET support material and filter material, and more particularly to a respirator that maintains a three-dimensional bowl shape when unfolded. Background Technology

[0002] A face mask is a protective device used to protect the respiratory tract. It primarily uses multiple layers of filter materials (such as polypropylene fibers, non-woven fabric, or cotton) to block airborne particles and droplets, thereby preventing viruses, bacteria, or contaminants. There are many types of face masks, which can be categorized by function and purpose into medical masks, N9 masks, and general non-medical masks. They can also be classified by appearance and structure, such as flat masks, folded masks, and bowl-shaped masks. Each type of mask has different applicable scenarios and protection levels depending on its design.

[0003] While traditional flat or folded masks offer basic protection, common drawbacks include low shielding efficiency, poor coverage, and the mouth and nose area easily coming into direct contact with the inner layer material during wear. This not only affects wearing comfort but may also reduce the protective effect. A bowl-shaped mask has emerged on the market. This bowl-shaped mask can fit the user's face better and form a stable support space in front of the user's mouth and nose, effectively preventing the mouth and nose from directly contacting the inner layer of the filter material, thus improving wearing comfort and overall fit.

[0004] However, in order to maintain the three-dimensionality of the supporting space, bowl-shaped masks usually adopt a fixed design, making it difficult to design multiple folds like traditional folding masks. This results in a relatively reduced contact area between the mask body and the outside world, which restricts the airflow channel and increases breathing resistance. Therefore, how to improve the insufficient breathability and high breathing resistance of bowl-shaped masks has become an issue that this technology urgently needs to solve. Utility Model Content

[0005] The main purpose of this invention is to provide a breathing mask that uses breathable PET material to completely cover the filter material. The breathing mask is folded and heat-pressed into a bowl shape by the two materials, so that the breathing mask can maintain a three-dimensional shape, rather than a flat shape that needs to be unfolded.

[0006] The secondary objective of this invention is that the bowl-shaped area is designed with dense and continuous folds, which keeps the breathing mask in a three-dimensional shape to increase the surface area in contact with the outside air, thereby significantly reducing the breathing resistance of the user when wearing the breathing mask and improving the comfort of wearing the mask.

[0007] To achieve the aforementioned objectives, this utility model provides a respirator mask, characterized in that it comprises:

[0008] A mask body comprises a support material layer bonded to the front of a filter material layer, wherein the support material layer is made of PET material that completely covers and adheres to the filter material layer. The mask body includes a bowl-shaped portion and an outer pressing body. The bowl-shaped portion has multiple folds arranged continuously from top to bottom to sequentially form an upper section, a front extension section, and a lower section. The outer pressing body has an integrally formed ring around the outer edge of the bowl-shaped portion and two lugs located on opposite sides of the ring. Each lug forms a drawstring portion, such that the two drawstring portions are located on opposite sides of the mask body.

[0009] An elastic cord is installed at both of the cord receiving parts, so that the elastic cord and the mask body together form a wearing space that can be placed over a user's head.

[0010] The upper section is higher than the lug, the lower section is lower than the lug, and the front extension section is level with the lug. Furthermore, the number of folds in the front extension section is greater than the number of folds in either the upper or lower section.

[0011] The elastic cords are installed on the two cord-connecting parts, so that the elastic cords and the mask body together form a wearing space that can be placed on the user's head; and the support material layer is a PET material that completely covers and adheres to the filter material layer.

[0012] Furthermore, the height of the upper section is higher than that of the lug, the height of the lower section is lower than that of the lug, and the height of the forward extension section is flush with that of the lug. The number of folds in the forward extension section is greater than the number of folds in either the upper section or the lower section.

[0013] The upper section has its upper sides tapered inward to form a nose rest that matches the shape of the bridge of the nose, while the lower section has a larger folding and unfolding range than the forward section to form a bottom rest that covers the chin. Furthermore, the multiple folds of the nose rest and the bottom rest are fully unfolded, so that the nose rest and the bottom rest have a flat profile. In addition, the front of the protruding ear is a smooth surface, while the back is a rough surface.

[0014] Furthermore, the breathing mask also includes a cushion connected to the back of the outer pressing body. The cushion has a joint portion that fits the ring and the lug, and a contact portion that extends from the joint portion toward the center of the bowl, so that a gap space is formed between the bowl and the contact portion.

[0015] In addition, the contact portion forms a guide groove at the corresponding position of the upper section. When the guide groove contacts the bridge of the nose, the padding material on both sides of the guide groove will be deformed to match the shape of the bridge of the nose. After the lug and the joint are bent forward, they are joined to the front of the bowl, so that a first depression is generated on the back of the bowl and a second depression is generated on the front of the bowl. The first depression and the second depression together form a joint point connecting the lug and the joint.

[0016] The two connecting parts are configured as a longitudinal channel formed by the lug, the ring and the bowl, so that the elastic rope, after entering the two connecting parts, forms an upper rope segment that can be positioned above the ear and a lower rope segment that can be positioned below the ear.

[0017] In a preferred embodiment, the plurality of folds includes a first portion located in the upper section, a second portion located in the forward extension section, and a third portion located in the lower section. The folding angles of the first portion are all between 30 and 90 degrees, the folding angles of the second portion are all between -30 and 30 degrees, and the folding angles of the third portion are all between -30 and -90 degrees.

[0018] The feature of this invention is that the main body of the mask is formed by the support material layer combined with the front of the filter material layer, and the support material layer is completely covered and attached to the filter material layer by the PET material. In addition, the number of folds in the front section is greater than the number of folds in either the upper section or the lower section, so that the breathing mask can maintain a three-dimensional shape to increase the surface area in contact with the outside air, which greatly reduces the breathing resistance of the user when wearing the breathing mask and improves the comfort of use.

Detailed Implementation

[0027] The present invention will be further described below with reference to specific embodiments and accompanying drawings. The advantages and features of the present invention will become clearer with the description.

[0028] In the accompanying drawings, the directional terms such as "front," "back," "left," "right," "up," and "down" refer to the direction the user faces when wearing the mask.

[0029] Please see Figure 1 and Figure 4 As shown, this utility model provides a breathing mask 1, which includes a mask body 2, an elastic strap 3 and a cushion 4. The mask body 2 is composed of a support material layer 21 bonded to the front of a filter material layer 22. The front of the filter material layer 22 faces forward and the back faces the user's face. The mask body 2 includes a bowl 23 and an outer pressing body 24. The bowl 23 has a plurality of folds 25 arranged continuously from top to bottom to sequentially form an upper section 231, a front extension section 232 and a lower section 233.

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, both the front and back sides of the bowl 23 are rough surfaces, and the number of folds in the front extension section 232 is greater than the number of folds in either the upper section 231 or the lower section 233.

[0031] Please see Figure 5 , Figure 6 and Figure 7As shown, the peripheral pressing body 24 has an integrally formed ring 241 on the outer edge of the bowl body 23 and two lugs 242 located on opposite sides of the ring 241. The front of the ring 241 and the two lugs 242 are both smooth surfaces, while the back is both rough surfaces. The peripheral pressing body 24 presses down the left and right ends of each fold 25, so that the plurality of folds 25 are fixed on the bowl body 23.

[0032] The upper section 231 is higher than the lug 242, the lower section 233 is lower than the lug, and the front extension section 232 is level with the lug 242. The number of folds in the front extension section 232 is greater than the number of folds in either the upper section 231 or the lower section 233, so that the breathing mask 1 has a larger breathing area to reduce breathing resistance.

[0033] The supporting material layer 21 is completely covered and adhered to the filter material layer 22 by a PET material. The rough surface on the front of the bowl 23, the smooth surface on the front of the ring 241 and the two lugs 242 are all made of the PET material. However, the rough surface has multiple pores in its structure, while the smooth surface has no pores, allowing air to enter the user's body from the outside through the bowl 23, while the smooth surface is completely non-breathable.

[0034] Please see Figure 1 , Figure 3 and Figure 4 As shown, the upper section 231 has its upper sides recessed to form a nose rest 231a that conforms to the shape of the bridge of the nose, while the lower section 233 has its folds 25 unfolded to a greater extent than the front section 232 to form a bottom rest 233a that covers the chin. The multiple folds 25 of the nose rest 231a and the bottom rest 233a are fully unfolded, so that the nose rest 231a and the bottom rest 233a have a flat contour, thereby allowing the mask body 2 to conform to the user's facial contour, so that the nose rest 231a fits the bridge of the nose and the bottom rest 233a fits the chin.

[0035] Please see Figure 2 , Figure 4 and Figure 6As shown, the cushion 4 is connected to the back of the outer pressing body 24 and has a joint 41 that fits the ring 241 and the lug 242, and a contact portion 42 that extends from the joint 41 toward the center of the bowl 23, so that a gap space is formed between the bowl 23 and the contact portion 42. The contact portion 42 has a guide groove 421 formed at the corresponding position of the upper section 231. When the guide groove 421 contacts the bridge of the nose, the padding material on both sides of the guide groove 421 will be deformed to match the shape of the bridge of the nose. In this way, when the user wears the breathing mask 1, the user's face will only contact the contact portion 42 and will not contact the bowl 23 with the rough surface, so that the breathing mask 1 does not need to waste material to make a comfort layer that contacts the face.

[0036] Furthermore, since the cushion 4 is connected to the back of the outer pressing body 24, the left and right ends of the plurality of folds 25 can be clamped by the outer pressing body 24 and the cushion 4 respectively, thereby improving the stability of the plurality of folds 25.

[0037] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, after the lug 242 and the joint portion 41 are bent forward, they are joined to the front of the bowl body 23, so that a first recess 71 is generated on the back of the bowl body 23, and a second recess 72 is recessed downward from the joint portion 41 and formed on the front of the bowl body 23 through the lug 242. The first recess 71 and the second recess 72 are joined to the front of the bowl body 23 by melting the joint portion 41 and the lug 242. The first recess 71 and the second recess 72 together form a joint point connecting the lug 242 and the joint portion 41. The first recess 71 and the second recess 72 also have the smooth surface.

[0038] Each lug 242 forms a connecting part 26. The two connecting parts 26 are configured as a longitudinal channel surrounded by the lug 242, the ring 241, and the bowl 23, so that the two connecting parts 26 are located on opposite sides of the mask body 2. The elastic cord 3 is installed on the two connecting parts 26. After entering the two connecting parts 26, the elastic cord 3 forms an upper cord segment 31 that can be positioned above the ear and a lower cord segment 32 that can be positioned below the ear, so that the upper cord segment 31, the lower cord segment 32 and the mask body 2 together form a wearing space that can be put on the user's head.

[0039] Please see Figure 4 As shown, the plurality of folds 25 include a first portion 231b located in the upper section 231, a second portion 232a located in the forward extension section 232, and a third portion 233b located in the lower section 233. The folding angles of the first portion 231b are all between 30 and 90 degrees, the folding angles of the second portion 232a are all between -30 and 30 degrees, and the folding angles of the third portion 233b are all between -30 and -90 degrees. The number of folds in the second portion 232a is greater than the number of folds in either the first portion 231b or the third portion 233b.

[0040] The above descriptions and embodiments are merely exemplary and do not constitute any limitation on the patent scope of this utility model. Those skilled in the art should understand that modifications or substitutions to the details and form of the technical solution of this utility model can be made without departing from the spirit and scope of this utility model, but all such modifications and substitutions fall within the protection scope of this utility model.
