Abstract
Description
Technical Field
[0001] This application relates to the technical field of facial protection, and in particular to a wearable component and a face covering. Background Technology
[0002] Face coverings, masks, and other facial protective products are everyday items that help block harmful substances from entering the wearer's mouth and nose, block ultraviolet rays, and provide warmth. Ear loops are used to connect the face covering to the wearer's ears. To improve the fit of face coverings, elastic cords are usually used as ear loops, utilizing the elasticity of the cords to secure the face covering. However, if the cords are too elastic, the face covering will cause pressure on the wearer's face; if the cords are too weak, the face covering will not be securely fixed, affecting the fit between the face covering and the wearer's face. This results in poor fit for wearers with different face sizes. Utility Model Content
[0003] Therefore, it is necessary to provide a wearable component and a face cover to address the problem that the use of elastic cords as ear loops in traditional technologies results in poor fit of face covers for wearers with different face sizes.
[0004] The technical solution is as follows:
[0005] One embodiment provides a wearable component for a face cover, the face cover including a protective portion for covering the face, the wearable component comprising:
[0006] An ear loop, one end of which is connected to the protective part, and the ear loop is provided with a plurality of positioning parts, which are spaced apart along the extension direction of the ear loop; and
[0007] An adjusting member is connected to the protective part. The adjusting member has a connecting hole and a snap-fit hole. The snap-fit hole is connected to the connecting hole. The ear loop is movably passed through the connecting hole. The snap-fit hole is used to engage with the positioning part to prevent the ear loop from moving relative to the adjusting member along the extension direction of the connecting hole.
[0008] In the aforementioned wearable component, the ear loops are movably threaded through the connecting holes of the adjusting member. This allows the user to control the adjusting member to move back and forth along the extension direction of the ear loops via the connecting holes. During this process, the distance between the end of the ear loop connected to the protective part and the adjusting member changes, thereby altering the wearing length of the ear loops. After adjusting the wearing length of the ear loops to a suitable length using the aforementioned method, a locking mechanism is established between the positioning part on the ear loops and the locking hole on the adjusting member to prevent further movement of the adjusting member and to prevent changes in the wearing length of the ear loops. Compared to conventional technologies, the aforementioned wearable component can adjust the wearing length of the ear loops and prevent changes in the wearing length of the ear loops during the wearing of face coverings, thereby improving the fit between the face coverings and the wearer's face and enhancing the adaptability of the face coverings.
[0009] In one embodiment, the snap-fit hole includes a first snap-fit hole and a second snap-fit hole, the first snap-fit hole and the second snap-fit hole are spaced apart along the extension direction of the connecting hole, the diameter of the second snap-fit hole is larger than that of the second snap-fit hole, and when the ear strap is inserted into the connecting hole, the second snap-fit hole is close to the other end of the ear strap.
[0010] In one embodiment, the hole wall of the connecting hole has a first sidewall close to the protective part and a second sidewall away from the protective part. The second sidewall is provided with a pressing part that protrudes toward the first sidewall. The pressing part can press against a portion of the ear loop so that the ear loop is subjected to compressive force at that portion and shifts away from the protective part.
[0011] In one embodiment, the adjusting member has a plurality of snap-fit holes on at least two sides, and the ear strap has a positioning part on the corresponding side of the adjusting member. The snap-fit hole on each side of the adjusting member is used to snap into the positioning part on the corresponding side of the ear strap.
[0012] In one embodiment, the positioning portion is disposed on opposite sides of the ear strap.
[0013] In one embodiment, the positioning part is provided with a guide surface along the sliding direction of the ear loop;
[0014] Alternatively, the positioning part may be hemispherical.
[0015] In one embodiment, the distance between the edge of the snap hole along the extension direction of the connecting hole and the edge of the adjusting member is defined as D, and the distance between every two adjacent positioning portions of the ear strap is defined as d.
[0016] The values of D and d satisfy: D≤d≤1.1D.
[0017] In one embodiment, the adjusting member is further provided with a mounting hole for a connector for the face covering to pass through, so as to connect the adjusting member to the protective part;
[0018] And / or, one end of the ear loop connected to the protective part branches into at least two sub-loops, and the ends of the at least two sub-loops are connected to the protective part at intervals;
[0019] And / or, the end of the ear loop away from the protective part is a free end, and the width of the free end is greater than or equal to the diameter of the connecting hole.
[0020] In one embodiment, at least one of the ear strap and the adjustment member is made of an elastic material, and at least one preset directional dimension of the ear strap body is greater than the dimension of the corresponding direction of the connecting hole, so that the ear strap body is in an elastic interference state when it is inserted into the connecting hole.
[0021] In one embodiment, the wall thickness L of the adjusting member at the first end of the connecting hole and the wall thickness L1 of the adjusting member at the second end of the connecting hole satisfy the condition: L > L1.
[0022] Another embodiment provides a face covering including a protective part and a wearable component as described in any of the above embodiments, wherein one end of the ear strap and the adjustment member are respectively connected to the protective part, and the wearing length of the ear strap is adjusted by adjusting the ear strap to move relative to the adjustment member along the channel extension direction of the connection hole.
[0023] In the aforementioned mask, the ear loops are movably threaded through the connecting holes of the adjustment component. This allows the user to control the adjustment component to move back and forth along the extension direction of the ear loops via the connecting holes. During this process, the distance between the end of the ear loop connected to the protective part and the adjustment component changes, thus altering the wearing length of the ear loops. After adjusting the ear loop length to a suitable length using this method, a positioning part on the ear loop engages with a locking hole on the adjustment component to prevent further movement of the adjustment component and to prevent changes in the wearing length of the ear loops. Compared to traditional technologies, the aforementioned mask allows for adjustment of the ear loop length and prevents changes in the ear loop length during the wearing of the face covering, thereby improving the fit between the face covering and the wearer's face and enhancing the overall suitability of the face covering.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0043] Please see Figures 1 to 7 as well as Figure 10 One embodiment of this application provides a wearable component for a face covering 10. The face covering 10 includes a protective part 11 for covering the face. The wearable component includes an ear loop 100 and an adjustment member 200. One end of the ear loop 100 is connected to the protective part 11. The ear loop 100 is provided with a plurality of positioning parts 110, which are spaced apart along the extension direction of the ear loop 100. The adjustment member 200 is connected to the protective part 11. The adjustment member 200 has a connecting hole 210 and a snap-fit hole 220. The snap-fit hole 220 communicates with the connecting hole 210. The ear loop 100 is movable through the connecting hole 210. The snap-fit hole 220 and the positioning part 110 can be snapped together along the extension direction of the channel of the connecting hole 210.
[0044] In the aforementioned wearable component, the ear loop 100 is movably inserted through the connection hole 210 of the adjuster 200. Thus, the user can control the adjuster 200 to reciprocate along the extension direction of the ear loop 100 via the connection hole 210. During this process, the distance between the end of the ear loop 100 connected to the protective part 11 and the adjuster 200 changes, thereby altering the wearing length of the ear loop 100. After adjusting the wearing length of the ear loop 100 to a suitable length using the aforementioned method, the positioning part 110 on the ear loop 100 and the locking hole 220 on the adjuster 200 engage to prevent further movement of the adjuster 200 and thus prevent changes in the wearing length of the ear loop 100. Compared to conventional technologies, the aforementioned wearable component can adjust the wearing length of the ear loop 100 and prevent changes in the wearing length of the ear loop 100 during the wearing of the face covering 10, thereby improving the fit between the face covering 10 and the wearer's face and enhancing the adaptability of the face covering 10.
[0045] For illustrative purposes, the wearable component in this application embodiment can be applied to a mask 10, or a face shield or a hat brim face shield, etc. Correspondingly, the protective part 11 in this application embodiment can be the cover part of the mask 10 or face shield used to cover the mouth and nose, or the face shield part of a hat brim face shield, etc.
[0046] In addition, the adjusting member 200 is provided with a plurality of snap-fit holes 220 spaced apart along the extension direction of the connecting hole 210, and the ear strap 100 is provided with a positioning part 110. Of course, multiple positioning parts 110 can also be provided. This can also achieve the technical effects in the above embodiments. For those skilled in the art, without departing from the concept of this application, several modifications and improvements can be made, all of which fall within the protection scope of this application.
[0047] As further explained, one end of the ear loop 100 is connected to the protective part 11. The ear loop 100 can pass through the connecting hole 210 of the adjusting member 200 to achieve the connection between the ear loop 100 and the adjusting member 200. The adjusting member 200 can be connected to the protective part 11 so that the ear loop 100, the adjusting member 200, and the protective part 11 surround to form a wearing space. The wearer's ear passes through the wearing space to hang the ear loop 100 on the wearer's ear. The wearing length dimension of the ear loop 100 refers to the length of the portion of the ear loop 100 used to surround and form the wearing space, that is... Figure 1 and Figure 4 The length L in the equation.
[0048] Furthermore, in the above embodiments, the extension direction of the channel refers to the axial direction of the connecting hole 210 itself, which will not be repeated here.
[0049] Furthermore, when the wearer controls the adjustment member 200 to move relative to the ear loop 100 along its length, the size of the wearing space formed by the ear loop 100, the adjustment member 200, and the protective part 11 will change, that is, the wearing length of the ear loop 100 will change, so that the fit between the protective part 11 and the wearer's face will change. The positioning part 110 at different positions on the ear loop 100 and the snap-fit hole 220 on the adjustment member 200 will engage to prevent the adjustment member 200 from moving further after it is adjusted to the appropriate position, thus preventing the wearing length of the ear loop 100 from changing.
[0050] Please see Figure 10 In one embodiment, one end of the ear strap 100 is connected to the upper region of the protective part 11, and the adjustment member 200 is connected to the lower region of the protective part 11 to form a wearing space near the wearer's ear.
[0051] Please see Figures 1 to 6 In one embodiment, the ear strap 100 is elongated, and the extension direction of the ear strap 100 is the length direction of the elongated ear strap 100, that is... Figure 1 and Figure 4 The direction A in the diagram will not be elaborated upon here.
[0052] In one embodiment, at least one of the ear strap 100 and the adjustment member 200 is made of an elastic material, and at least one preset directional dimension of the ear strap 100 body is greater than the dimension of the corresponding direction of the connection hole 210, so that the ear strap 100 body is in an elastic interference state when it is inserted into the connection hole 210.
[0053] This design not only prevents the ear strap 100 from detaching from the connecting hole 210, but also allows at least one of the ear strap 100 and the connecting hole 210 to undergo elastic deformation when the position of the adjusting member 200 on the ear strap 100 needs to be adjusted, so as to adjust the wearing length of the ear strap 100.
[0054] The elastic ear loop 100 deforms more easily when passing through the connecting hole 210, reducing frictional resistance and enabling smooth length adjustment. Furthermore, the ear hook portion of the elastic ear loop 100 conforms to the shape of the ear, distributing pressure and reducing marks. When the wearer speaks or moves their head, the elastic ear loop 100 can slightly stretch and contract with facial movement, maintaining a proper fit to the face covering 10 while preventing the ear loop 100 from becoming too tight or slipping off.
[0055] The adjustment member 200 is made of an elastic material, and the edge of its locking hole 220 has a slight deformation capability, which helps to reduce the hard compression on the ear loop 100 positioning part 110, thereby reducing local stress. At the same time, the locking hole 220 of the adjustment member 200 can expand moderately due to the elastic material, and the rebound force generated by the deformation locks it in, making it easier for the positioning part 110 to be engaged and less likely to accidentally fall out. In addition, the fit between the positioning part 110 and the locking hole 220 is elastic, which can reduce wear and help extend service life.
[0056] Specifically, the elastic material used in this application embodiment is preferably an elastic material with a certain degree of flexibility, such as silicone or rubber. This application embodiment uses silicone as an example because silicone has strong waterproof and sweat-resistant properties, preventing mold growth due to sweat stains and is not easily deformed by moisture. Furthermore, it has a comfortable feel when in contact with the skin and strong adaptability to different temperature ranges. In addition, silicone has strong resilience and is not prone to elasticity decay, resulting in a longer service life.
[0057] Traditional ear loops are usually made of textile cords, which are often chemically treated with dyes and wrinkle-resistant agents. These cords can easily leave behind irritating substances and are not friendly to sensitive skin. Silicone, on the other hand, is a high-molecular polymer (mainly composed of silicon dioxide), which is chemically stable and does not contain common allergens (such as latex protein or chemical residues in textile dyes). It can also play a certain role in suppressing acne.
[0058] Furthermore, traditional textile ropes and straps use a surface dyeing process, which can easily fade after long-term use or washing, affecting their appearance. The ear loops 100 made of silicone material are uniformly colored with color masterbatch during production, and the color is integrated into the material, making them less likely to fall off due to friction, sweat, or washing.
[0059] In one embodiment, the wall thickness L of the adjusting member 200 at the first end of the connecting hole 210 and the wall thickness L1 of the adjusting member 200 at the second end of the connecting hole 210 satisfy the condition: L > L1.
[0060] With this configuration, the thicker end of the connecting hole 210 can provide a more reliable clamping effect for the ear strap 100. After the positioning part 110 of the ear strap 100 slides out of the snap-fit hole 220, the smooth section of the thicker end of the connecting hole 210 can still provide a reliable clamping force to the positioning part 110, thereby preventing the ear strap 100 from falling off the connecting hole 210.
[0061] Please see Figure 6 and Figure 7In some embodiments, the snap-fit hole 220 is located on the side wall of the adjusting member 200, and the snap-fit hole 220 is a through hole communicating with the connecting hole 210; in other embodiments, the snap-fit hole 220 is located on the inner wall of the connecting hole 210, and the snap-fit hole 220 is a blind hole communicating with the connecting hole 210. A blind hole can be understood as the snap-fit hole 220 having an opening only inside the adjusting member 200, and this opening communicating with the connecting hole 210. Of course, when multiple snap-fit holes 220 are provided on the adjusting member 200, some of the snap-fit holes 220 may be through holes, while others may be blind holes.
[0062] Please see Figures 6 to 9 In one embodiment, at least two snap-fit holes 220 are provided, and the at least two snap-fit holes 220 are spaced apart along the extension direction of the connecting hole 210. Each snap-fit hole 220 can be snapped into cooperation with at least one positioning part 110.
[0063] The snap-fit hole 220 is provided with at least two and is spaced apart along the extension direction of the connecting hole 210. Each snap-fit hole 220 can be snapped into at least one positioning part 110. In this way, the positioning stability of the adjustment member 200 on the ear strap 100 can be improved, and the adjustment member 200 can be further prevented from moving on the ear strap 100 after being adjusted to the appropriate position.
[0064] Please see Figures 6 to 9 In one embodiment, the snap-fit hole 220 includes a first snap-fit hole and a second snap-fit hole. The first snap-fit hole and the second snap-fit hole are spaced apart along the extension direction of the connecting hole 210. The diameter of the second snap-fit hole is larger than that of the second snap-fit hole. When the ear strap 100 passes through the connecting hole 210, the second snap-fit hole is close to the other end of the ear strap 100.
[0065] The larger second snap-fit hole is located near the other end of the ear strap 100 (i.e., the free end 130 of the ear strap 100), which allows the other end of the ear strap 100 to have more room to move, so as to avoid the ear strap 100 from contacting the wearer's face.
[0066] Further, please refer to Figures 6 to 9 In one embodiment, the adjusting member 200 has a plurality of snap-fit holes 220 on at least two sides, and the ear strap 100 and the adjusting member 200 have a positioning part 110 on the corresponding side. The snap-fit hole 220 on each side of the adjusting member 200 is used to snap-fit with the positioning part 110 on the corresponding side of the ear strap 100.
[0067] At least two of the adjusting members 200 are provided with multiple snap-fit holes 220 to engage with the positioning part 110 on the corresponding side of the ear strap 100. This makes the positioning effect between the adjusting member 200 and the ear strap 100 more stable and reliable, and further prevents the adjusting member 200 from moving on the ear strap 100 after being adjusted to the appropriate position.
[0068] Please see Figure 3 In one embodiment, the positioning part 110 is disposed on opposite sides of the ear strap 100.
[0069] The positioning portions 110 located on opposite sides of the ear loop 100 can engage with the corresponding snap-fit holes 220 on both sides of the adjustment member 200, so that the snap-fit between the adjustment member 200 and the ear loop 100 is symmetrical, which helps to improve the stability of the engagement under force.
[0070] Please see Figure 3 , Figures 6 to 9 In one embodiment, the positioning part 110 is provided with a guide surface along the sliding direction of the ear strap 100.
[0071] The guide surface design allows the ear strap 100 to slide more smoothly, thereby improving the user experience of the wearable components.
[0072] Understandably, in other embodiments, the positioning part 110 is hemispherical, and the hemispherical positioning part 110 can also improve the smoothness of the ear strap 100 when sliding, and improve the user experience of the wearable component.
[0073] Please see Figure 3 , Figures 6 to 9 In one embodiment, the distance between the edge of the snap hole 220 along the extension direction of the connecting hole 210 and the edge of the adjusting member 200 is defined as D, and the distance between every two adjacent positioning portions 110 of the ear strap 100 is defined as d.
[0074] The values of D and d satisfy: D≤d≤1.1D.
[0075] With this configuration, the part of the structure between the edge of the snap-fit hole 220 and the edge of the adjustment member 200 can be effectively snapped with the two adjacent positioning parts 110, thus preventing the adjustment member 200 from still being able to move along the extension direction of the ear strap 100 after the snap-fit hole 220 and the positioning part 110 are snapped together.
[0076] Please see Figure 3 , Figures 6 to 9 In some embodiments, the positioning part 110 includes a first sub-protrusion 111 and a second sub-protrusion 112. The first sub-protrusion 111 is provided with a plurality of protrusions and is spaced apart on one side of the ear strap 100. The second sub-protrusion 112 is provided with a plurality of protrusions and is spaced apart on the other side of the ear strap 100. The snap-fit hole 220 includes a first snap-fit sub-hole 221 and a second snap-fit hole 222. The first snap-fit hole 221 can snap-fit with the first sub-protrusion 111, and the second snap-fit hole 222 can snap-fit with the second sub-protrusion 112.
[0077] For example, the first sub-protrusion 111 and the second sub-protrusion 112 can be respectively located on adjacent sides of the ear strap 100, or the first sub-protrusion 111 and the second sub-protrusion 112 can be respectively located on opposite sides of the ear strap 100. The first snap-fit hole 221 corresponds to the position of the first sub-protrusion 111, and the second snap-fit hole 222 corresponds to the position of the second sub-protrusion 112. This will not be elaborated further here.
[0078] exist Figure 9 In the embodiment shown, the first sub-protrusion 111 and the second sub-protrusion 112 are respectively located on opposite sides of the ear strap 100 along the width direction.
[0079] Furthermore, the width direction of the ear strap 100 is... Figure 3 The direction B in the diagram will not be elaborated upon here.
[0080] Please see Figures 1 to 5 In one specific embodiment of this application, there are eleven first sub-protrusions 111, and the distance between two adjacent first sub-protrusions 111 is 4mm, so that the cumulative adjustment range of the adjustment member 200 is 40mm, so as to adapt to different face shapes and wearing tightness requirements; the second sub-protrusion 112 is similar to the first sub-protrusion 111, and will not be described again here.
[0081] Please see Figure 3 , Figure 6 and Figure 7 In one embodiment, a first snap-fit portion 240 is provided between any two adjacent first snap-fit holes 221, and a first snap-fit groove 113 is formed between any two adjacent first sub-protrusions 111. The first snap-fit portion 240 is used to snap-fit with the first snap-fit groove 113.
[0082] The first snap-fit portion 240 can snap into the first snap-fit groove 113 formed between the two first sub-protrusions 111, thereby further improving the positioning reliability between the ear strap 100 and the adjustment member 200.
[0083] Please see Figure 3 , Figure 8 and Figure 9 In one embodiment, a second snap-fit portion 250 is provided between any two adjacent second snap-fit holes 222, and a second snap-fit groove 114 is formed between any two adjacent second sub-protrusions 112. The second snap-fit portion 250 is used to snap-fit with the second snap-fit groove 114.
[0084] The second locking part 250 can be locked into the second locking groove 114 formed between the two second sub-protrusions 112, thereby further improving the positioning reliability between the ear strap 100 and the adjustment member 200.
[0085] In one embodiment, the wall of the connecting hole 210 is provided with a pressing part protruding in a preset direction. The pressing part can press against a portion of the ear loop 100 so that the ear loop 100 bends in the opposite direction in that portion.
[0086] The pressing part protruding along the preset direction can press against a part of the ear strap 100, causing the ear strap 100 to bend in the opposite direction at the pressed position, thus creating an inflection point. In this way, when the end of the ear strap 100 away from the protective part 11 passes through the connecting hole 210 of the adjusting member 200, the ear strap 100 will bend and move away from the wearer's face, thereby preventing the ear strap 100 from contacting the wearer's skin and affecting the wearing comfort.
[0087] As an explanation, the preset direction in the above embodiment refers to the direction towards the wearer's face. In this way, when the ear loop 100 bends in the opposite direction under the action of the pressure part, it can move away from the wearer's face, thereby avoiding the ear loop 100 from contacting the wearer's skin and affecting the wearing comfort.
[0088] Further, please refer to Figure 7 and Figure 9 The outer wall of the adjusting member 200 has a recess 230, and a protruding pressing part is formed in the wall of the connecting hole 210 at a position corresponding to the recess 230, thereby pressing the ear loop 100 and causing the ear loop 100 to bend.
[0089] In one embodiment, the hole wall of the connecting hole 210 has a first sidewall close to the protective part 11 and a second sidewall away from the protective part 11. The second sidewall is provided with a pressing part that protrudes toward the first sidewall. The pressing part can press against a portion of the ear loop 100 so that the ear loop 100 is subjected to compressive force at that portion and shifts away from the protective part 11.
[0090] This design allows the ear loop 100 to shift and bend away from the protective part 11 when it is bent, thus preventing the ear loop 100 from contacting the wearer's skin and affecting wearing comfort.
[0091] Please see Figures 6 to 9 as well as Figure 10 In one embodiment, the adjusting member 200 is further provided with a connecting portion 260, which is used to connect with the protective portion 11.
[0092] The connecting portion 260 of the adjusting member 200 is used to connect with the protective portion 11 to realize the connection between the adjusting member 200 and the protective portion 11.
[0093] Optionally, the connection between the connecting part 260 and the protective part 11 can be by bonding or by hot pressing, depending on the specific requirements. No specific limitation is made here.
[0094] Please see Figures 6 to 9 as well as Figure 10 In one embodiment, the adjustment member 200 is further provided with a mounting hole 270 for the connector 300 of the face covering 10 to pass through, so as to connect the adjustment member 200 to the protective part 11.
[0095] The connector 300 of the face covering 10 passes through the mounting hole 270 to achieve the connection between the adjustment member 200 and the protective part 11. The connection effect is reliable and the implementation cost is low.
[0096] Furthermore, the connector 300 includes a connecting ring that connects to the protective part 11. The connecting ring passes through the mounting hole 270 to realize the connection between the adjusting member 200 and the protective part 11.
[0097] Furthermore, the connecting ring is made of fabric that is skin-friendly, breathable, and tear-resistant.
[0098] In one embodiment, a mounting hole 270 is formed in the connecting portion 260, and the connector 300 passes through the mounting hole 270 on the connecting portion 260 and is connected to the protective portion 11.
[0099] Please see Figures 1 to 2 In one embodiment, one end of the ear strap 100 connected to the protective part 11 branches into at least two sub-straps 120, and the ends of the at least two sub-straps 120 are connected to the protective part 11 at intervals.
[0100] At least two sub-straps 120 formed by forking at one end of the ear strap 100 can be connected to the protective part 11. This not only improves the connection strength between the ear strap 100 and the protective part 11, but also distributes the tension of the ear strap 100 evenly on the protective part 11, thereby reducing the wearer's local pressure and improving wearing comfort.
[0101] exist Figure 1 and Figure 2 In the embodiment shown, there are two sub-strips 120, both of which are used to connect to the protective part 11, thereby improving the connection strength and wearing comfort.
[0102] Furthermore, the thickness of the sub-band 120 gradually decreases in the direction away from the earband 100 to achieve a seamless fit with the high-viscosity adhesive layer of the protective part 11.
[0103] Understandably, in other embodiments, a sub-band 120 may also be provided, such as... Figure 4 and Figure 5 As shown, it will not be elaborated further here.
[0104] Please see Figures 1 to 5In one embodiment, the end of the ear loop 100 away from the protective part 11 is a free end 130, and the width of the free end 130 is greater than or equal to the diameter of the connecting hole 210.
[0105] This design can, to some extent, prevent the adjustment element 200 from falling off the ear strap 100, thus improving the wearing reliability of the face covering 10.
[0106] Furthermore, the width of the ear strap 100 gradually increases in the direction toward the free end 130 to limit the adjustment member 200 and prevent the adjustment member 200 from falling off the ear strap 100.
[0107] Another embodiment provides a face covering 10, which includes a protective part 11 and a wearable component as described in any of the above embodiments. One end of an ear strap 100 and an adjustment member 200 are respectively connected to the protective part 11. The wearing length of the ear strap 100 is adjusted by moving the ear strap 100 relative to the adjustment member 200 along the extension direction of the channel of the connection hole 210.
[0108] The ear loop 100 is movably inserted through the connection hole 210 of the adjuster 200. Thus, the user can control the adjuster 200 to move back and forth along the extension direction of the ear loop 100 via the connection hole 210. During this movement, the distance between the end of the ear loop 100 connected to the protective part 11 and the adjuster 200 changes, thereby changing the wearing length of the ear loop 100. After adjusting the wearing length of the ear loop 100 to a suitable length using the above method, the positioning part 110 on the ear loop 100 and the snap-fit hole 220 on the adjuster 200 are engaged to prevent further movement of the adjuster 200 and to prevent changes in the wearing length of the ear loop 100. Compared with conventional technology, the face covering 10 described above can adjust the wearing length of the ear loop 100 and prevent changes in the wearing length of the ear loop 100 during the wearing process, thereby improving the fit between the face covering 10 and the wearer's face and enhancing the adaptability of the face covering 10.
[0109] As an explanation, the face covering in the above embodiments can be a mask, a face shield, or a hat brim face shield, etc. Correspondingly, the protective part 11 can be the cover part of the face covering 10 or the face shield used to cover the mouth and nose, or the face shield part of a hat brim face shield, etc.
[0110] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0111] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
