Description

Technical Field

[0001] This invention belongs to the field of mask technology, specifically relating to a drinkable mask and its manufacturing process. Background Technology

[0002] A face mask is a personal protective device worn on the face that covers the mouth and nose area. It is mainly used to block harmful substances such as particulate matter, droplets, bacteria, and viruses in the air and is widely used in medical protection, industrial protection, and daily life.

[0003] In existing technologies, common mask structures include multiple layers of non-woven fabric, meltblown fabric, and other materials, which filter airborne particles through physical filtration and electrostatic adsorption. However, these masks have the following drawbacks during use: wearers must remove the mask to perform daily activities such as drinking and eating, resulting in interruption of protection and increasing the risk of exposure to polluted external environments. Especially in medical, public health, or high-risk environments, frequent removal and wearing of masks not only affects ease of use but may also reduce protective effectiveness and increase the possibility of cross-infection. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a drinkable face mask to solve the existing problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a drinkable mask, the structure of which includes a mask body, the mask body including an upper connecting piece, a lower connecting piece and a lower support piece connected in sequence from top to bottom; The upper connecting piece, lower connecting piece, and lower support piece are arranged in a gradient and attached to each other inwards and outwards. The three are connected by at least a portion of their sides. The upper connecting piece and the lower connecting piece form a breathing port for breathing, and the lower connecting piece and the lower support piece form a drinking port for drinking water.

[0006] As a further improvement, the lower support piece is made of at least two connecting pieces in which at least a portion of each other are attached, and is attached to the inner side of the lower connecting piece by both sides of the lower support piece.

[0007] As a further improvement, the inner side of the upper connecting piece is provided with a support portion for shaping, the support portion having a receiving cavity, and a support strip being provided inside the receiving cavity.

[0008] As a further improvement, the two connecting pieces are joined together by heat pressing without leaving a trace, and a drinking spout is formed between the connection point and the lower connecting piece for drinking water.

[0009] As a further improvement, the lower connecting piece is attached to the inner side of the upper connecting piece by both sides, and the lower connecting piece has an arc-shaped third opening in the middle, forming a breathing port for nasal breathing through the third opening and the upper connecting piece.

[0010] As a further improvement, the upper connecting piece is provided with an anti-slip strip and a first opening for conforming to the contour of the eye. The anti-slip strip has connecting parts on both sides and is connected to the upper connecting piece through the connecting parts. The anti-slip strip has a second opening in the middle that matches the first opening.

[0011] As a further improvement, the inner side of the anti-slip strip is provided with at least a portion of the adhesive strip, which is made of rubber strip or silk.

[0012] As a further improvement, the mask body is provided with reinforcing patches on both sides. The reinforcing patches are sequentially attached to the inner sides of the upper connecting piece, the lower connecting piece, and the lower support piece. The reinforcing patches are also provided with adjustable ear loops.

[0013] As a further improvement, the bottom of the mask body is also provided with a shawl for wrapping around the neck, at least a portion of which is connected to the two side edges of the mask body.

[0014] The present invention also provides a manufacturing process using the above-mentioned drinkable face mask, the process comprising the following steps: Step S1: Take a number of single-layer base fabrics, apply hot-press adhesive strips to a portion of the single-layer base fabrics, and then hot-press them together using a hot press to create a double-layer base fabric. Step S2: Place the single-layer and double-layer base fabrics on the cutting machine and cut out several corresponding shapes of upper connecting pieces, lower connecting pieces, lower support pieces, anti-slip strips and reinforcing patches. The upper connecting pieces and anti-slip strips are double-layer base fabrics, while the lower connecting pieces and lower support pieces are single-layer base fabrics. Step S3: Next, take out the two lower support pieces and use a hot-cutting machine to perform a seamless hot-press connection; Step S4: Attach hot-press adhesive strips to both sides of the upper connecting piece, lower connecting piece, and anti-slip strip in sequence, then connect them sequentially using a hot press. Step S5: Apply adhesive strips to the reinforcing patch and stick it to both sides of the upper connecting piece, lower connecting piece, and anti-slip strip after the connection is completed. Place the ear loops into the inner layer of the reinforcing patch and iron them in place with an iron. This completes the semi-finished product of the mask body. Step S6: The semi-finished product is hot-pressed and shaped at high temperature. Finally, the lower support piece is fixed to both sides of the lower connecting piece with hot-pressing adhesive strips to complete the finished mask body.

[0015] The beneficial effects of this invention are as follows: The drinking mask provided by this invention allows the wearer to breathe more smoothly through the breathing port set between the upper and lower connecting pieces. At the same time, the arc-shaped third opening makes the airflow smoother. In addition, there is a drinking port formed between the lower connecting piece and the lower support piece, which allows the wearer to drink water in time even when wearing the mask without having to frequently remove the mask. Furthermore, the soft lower support piece can better support the chin, and the size of the drinking port can be selected by manually pulling the lower support piece, which is quite convenient.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Example 1 like Figure 1-4 As shown, the structure of a drinkable face mask according to an embodiment of the present invention will be described in detail. It includes a face mask body 1, which includes an upper connecting piece 11, a lower connecting piece 12 and a lower support piece 13 connected in sequence from top to bottom. The lower support piece 13 is used to support the chin. The upper connecting piece 11, the lower connecting piece 12, and the lower support piece 13 are arranged in a gradient and are attached to each other inwards and outwards. The three are connected by at least a portion of their two sides. That is, the upper connecting piece 11 and the lower connecting piece 12 are connected by at least a portion of their two sides, and the lower connecting piece 12 and the lower support piece 13 are connected by at least a portion of their two sides. A breathing port 100 for breathing is formed between the upper connecting piece 11 and the lower connecting piece 12. This breathing port 100 is mainly used for breathing through the nose. A drinking port 101 for drinking water is formed between the lower connecting piece 12 and the lower support piece 13. This drinking port 101 not only facilitates breathing through the mouth, but can also be made larger by pulling the lower support piece 13, so that it can be used for drinking water or beverages.

[0020] Please see Figure 2 , 3 As shown, the lower support piece 13 is made of at least two connecting sub-pieces 131 that are attached to each other in the left and right or top and bottom. In this embodiment, the lower support piece 13 is made of two connecting sub-pieces 131 that are attached to each other in the left and right. That is, the lower support piece 13 is formed by connecting at least a portion of the two connecting sub-pieces 131 together. Moreover, the lower support piece 13 formed by connecting the two connecting sub-pieces 131 is attached to the inner side of the lower connecting piece 12 through the two sides of the lower support piece 13.

[0021] Please see Figure 1-3As shown, the two connecting pieces 131 are joined together by heat-pressing without leaving a trace. This heat-pressing process gives the mask body 1 a better appearance. To accommodate the space for drinking water, the connection point of the two connecting pieces 131 is spaced apart from the lower connecting piece 12. When the user wears the mask, this space forms a drinking spout 101. This drinking spout 101 can be made by selecting appropriate sizes of the lower connecting piece 12 and connecting pieces 131 according to actual production needs, thus forming drinking spouts of different sizes. The lower support plate 13 is made of a single-layer base fabric, which is softer and does not use high-temperature shaping during production. This gives it better curvature and flexibility, allowing it to comfortably support the chin. When in use, gently pulling the lower support plate 13 will provide more space for the drinking spout 101, making it more convenient to drink water without discomfort. When the user wants to drink water, they can simply insert the straw into the drinking spout 101. The drinking spout 101 can also be made more spacious by manually pulling the lower support plate 13.

[0022] Please see Figure 6 As shown, as a further improvement, the inner side of the upper connecting piece 11 is provided with a support portion 40 for shaping. The support portion 40 has a receiving cavity 41, and a support strip 42 is provided in the receiving cavity 41. Specifically, there is a receiving cavity 41 between the support portion 40 and the upper connecting piece 11 to accommodate the support strip 42. The receiving cavity 41 forms an opening 43 on any side of the support portion 40 for inserting the support strip 42. The opening 43 is used for inserting the support strip 42. At the same time, at least a portion of the support portion 40 at the opening 43 is connected and closed with the upper connecting piece 11 to form a closed portion 44 for restricting and fixing the support strip 42. In use, the support strip 42 is aligned with the opening 43 and inserted into the receiving cavity 41 that is completely inside the support portion 40. Then, the support strip 42 is moved downward so that it abuts against the closed portion 44 formed by the connection and closure of at least a portion of the support portion 40 and the upper connecting piece 11, thereby making the support strip 42 fixed in the receiving cavity 41 and not easy to fall out.

[0023] Please see Figures 1-3 As shown, the lower connecting piece 12 is attached to the inner side of the upper connecting piece 11 by both sides, and the lower connecting piece 12 has an arc-shaped third opening 121 in the middle. The third opening 121 is used to increase airflow, and the lower connecting piece 12 forms a breathing port 100 for nasal breathing through the third opening 121 and the upper connecting piece 11. The breathing port 100 can be made by selecting the appropriate size of the lower connecting piece 12 and the upper connecting piece 11 according to actual production needs, thereby forming breathing ports 100 of different sizes. The breathing port 100 formed by the arc-shaped third opening 121 makes it easier for the user to breathe, and the exhaled airflow can be better exhaled from the third opening 121, so that even if the mask is worn for a long time, it will not feel stuffy.

[0024] Please see Figures 3-4 As shown, the upper connecting piece 11 is provided with an anti-slip strip 14 and a first opening 111 for conforming to the contour of the eye. The first opening 111 conforms to the upper contour of the eye. The anti-slip strip 14 is provided with connecting parts 140 on both sides and is connected to the upper connecting piece 11 through the connecting parts 140. The anti-slip strip 14 is provided with a second opening 141 in the middle that matches the first opening 111. The second opening 141 conforms to the lower contour of the eye. Therefore, the first opening 111 and the second opening 141 form an observation hole for the user to observe the eye. At the same time, when the anti-slip strip 14 is in use, it conforms to the forehead of the human body and can better prevent direct sunlight or cold wind, so that the entire face can be protected.

[0025] Please see Figures 3-5 As shown, the inner side of the anti-slip strip 14 is provided with at least a portion of the adhesive strip 142. The adhesive strip 142 may be partially provided on the anti-slip strip 14, or, depending on cost and actual user needs, may be designed to be an adhesive strip 142 with the same outline size as the anti-slip strip 14 to increase the contact area and improve anti-slip performance. In this embodiment, it is partially provided on the anti-slip strip 14. The adhesive strip 142 is made of rubber strip or silk. To meet different needs, for example, an adhesive strip 142 made of rubber strip can be pasted on the inner side of the anti-slip strip 14. When the user wears the mask body 1, the adhesive strip 142 on the inner side of the anti-slip strip 14 that is in contact with the forehead increases the friction with the forehead due to the anti-slip effect of the rubber, making the anti-slip strip 14 less likely to slip off. Even during large-scale walking, the anti-slip strip 14 is not likely to fall off the forehead.

[0026] If a silk-made adhesive tape 142 is used to adhere to the inside of the anti-slip strip 14, when the user wears the mask body 1, the adhesive tape 142 on the inside of the anti-slip strip 14 that adheres to the forehead can increase the coolness of the forehead due to the cooling effect of the silk. When used in summer sun protection scenarios, the silk-made adhesive tape 142 can bring a cool feeling to the human face to reduce the discomfort caused by hot weather. In this embodiment, the adhesive tape 142 will be made of 30%-100% silk.

[0027] Please see Figure 3As shown, the mask body 1 is also provided with reinforcing patches 20 on both sides. The reinforcing patches 20 are sequentially attached to the inner sides of the upper connecting piece 11, the lower connecting piece 12, and the lower support piece 13. After the upper connecting piece 11, the lower connecting piece 12, and the lower support piece 13 are connected, the mask body 1 is formed. The reinforcing patches 20 are also provided with adjustable ear loops 21. Due to prolonged wear and repeated pulling of the ear loops 21, the connection with the mask body 1 is prone to tearing or damage. Therefore, in order to reinforce both sides of the mask body 1, reinforcing patches 20 are provided to improve the tensile strength of the connection. As a preferred embodiment, the reinforcing patches can also be made of 100% silk, thereby increasing protection through the tensile strength of silk. At the same time, silk can also improve the cooling sensation, making the face more comfortable.

[0028] The present invention also provides a manufacturing process using the above-mentioned drinkable face mask, the process comprising the following steps: Step S1: Take a number of single-layer base fabrics, apply hot-press adhesive strips to a portion of the single-layer base fabrics, and then hot-press them together using a hot press to create a double-layer base fabric. Step S2: Place the single-layer and double-layer base fabrics on the cutting machine and cut out several corresponding shapes of upper connecting piece 11, lower connecting piece 12, lower support piece 13, anti-slip strip 14 and reinforcing patch 20. Among them, the upper connecting piece 11 and anti-slip strip 14 are double-layer base fabrics, and the lower connecting piece 12 and lower support piece 13 are single-layer base fabrics. Step S3: Next, take out the two lower support pieces 13 and use a hot-cutting machine to perform a seamless hot-press connection; Step S4: Attach hot-pressing adhesive strips to both sides of the upper connecting piece 11, lower connecting piece 12, and anti-slip strip 14 in sequence, then connect them sequentially using a hot press. Step S5: Apply adhesive strips to the reinforcing patch 20 and stick it to both sides of the upper connecting piece 11, lower connecting piece 12 and anti-slip strip 14 after the connection is completed. Place the ear loops 21 into the inner layer of the reinforcing patch 20 and iron them with an iron to fix them, thus completing the semi-finished product of the mask body. Step S6: The semi-finished product is hot-pressed and shaped at high temperature. Finally, the lower support piece 13 is fixed to both sides of the lower connecting piece 12 by hot-pressing adhesive strips to complete the finished mask body.

[0029] Example 2 For the sake of brevity, the parts that are the same as in Embodiment 1 will not be described again. The main focus here is on the structure that is different from that in Embodiment 1. The only difference between Embodiment 2 and Embodiment 1 is the shawl section.

[0030] Please see Figure 7 , 6As shown, in this embodiment, the bottom of the mask body 1 is also provided with a shawl 30 for wrapping around the neck. At least a portion of the shawl 30 is connected to the two side edges of the mask body 1. In order to further enhance protection, a shawl 30 for wrapping around the neck can be added to the bottom of the mask body 1 so that the entire neck can also be protected. Even in hot weather, the face will not be protected but the neck will not be sunburned. As a preferred embodiment, a corresponding connecting structure can be provided for the shawl 30 for wrapping and locking the shawl so that the shawl can stably wrap around the neck and will not fall off. As a conventional technique for those skilled in the art, any of the following methods, including but not limited to Velcro structure, snap structure, and buckle structure, can be used as the connecting structure.

[0031] Example 3 For the sake of brevity, the parts that are the same as in Embodiment 1 will not be described again. The main focus here is on the structure that is different from that in Embodiment 1 of the present invention. The only difference between Embodiment 3 and Embodiment 1 is the anti-slip strip.

[0032] Please see Figure 9 As shown, in this embodiment, the anti-slip strip 14 in embodiment 1 is replaced with an anti-slip cap 40. The anti-slip cap 40 is located on the top of the mask body 1 and at least part of it is connected to the two side edges of the mask body 1. The protective cap 40 can provide better sunshade effect and also has the protective performance of a mask. It can achieve an integrated design of 360-degree all-round protection for the head, face and neck, and is suitable for more scenarios of outdoor activities in summer.

[0033] Example 4 For the sake of brevity, the parts that are the same as in Embodiment 1 will not be described again. The main focus here is on the structure that is different from that in Embodiment 1 of the present invention. The only difference between Embodiment 4 and Embodiment 1 is the lower support piece.

[0034] Please see Figures 10-11 As shown, in this embodiment, the lower support piece 13 is made of two connecting sub-pieces 131 that are attached to each other. That is, the lower support piece 13 is formed by the upper and lower ends of the two connecting sub-pieces 131 being attached to each other. The lower support piece 13 formed by the connection of the two connecting sub-pieces 131 is attached to the inner side of the lower connecting piece 12 through the two sides of the lower support piece 13. The design of the upper and lower parts being attached to each other makes the lower support piece 13 better support the chin part and more naturally. In addition, a breathable sheet is set on the upper connecting sub-piece 131, and a breathable hole 1310 is opened on the breathable sheet to increase the breathability. While increasing the breathability, the lower connecting piece 12 is located on its outer side and has a warming effect. Therefore, opening a breathable hole can not only increase the breathability but also maintain the warming effect. The size of the breathable sheet should not be too large, just enough to meet the breathing requirements of the mouth and nose.

[0035] Example 5 For the sake of brevity, the parts that are the same as in Example 4 will not be described again. The main focus here is on the structure that is different from that in Example 4 of the present invention. The only difference between Example 5 and Example 4 is the difference in air permeability.

[0036] Please see Figure 12 As shown, as another preferred embodiment, ventilation holes 1310 can be directly opened on the connecting sub-piece 131 located above. By directly punching holes, the breathability is increased, while the lower connecting piece 12 on the outside still ensures the warmth of the mask. Compared with embodiment 4, this can reduce the cost.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
