Description

Technical Field

[0001] This invention relates to face masks, and more specifically, to a face mask with a knob. Background Technology

[0002] Generally, operators performing welding and other similar operations are exposed to harmful substances such as dust, so they wear face masks to prevent these substances from entering their respiratory system through their mouth and nose.

[0003] On the other hand, welding and other similar operations can take a long time, so operators need to wear masks on their faces for extended periods until the work is finished. Furthermore, to maximize the protection against harmful substances, operators wear masks as tightly as possible to their faces, making it difficult to breathe or speak while wearing a mask.

[0004] Therefore, operators frequently need to temporarily remove and then re-putt their masks during work to rest or conduct work-related conversations. In these situations, it is crucial to minimize the operator's exposure to hazardous substances; therefore, the process of removing and re-putting the mask must be simple and easy. Furthermore, during mask removal, a predetermined distance must be maintained between the mask and the operator's face to prevent the mask from completely detaching from the operator. Summary of the Invention

[0005] Technical issues

[0006] The technical challenge of this invention is to provide a face mask that allows the wearer to quickly and efficiently put on and take off the mask.

[0007] Technical solution

[0008] An embodiment of the present invention provides a face mask, comprising: a body disposed on the face of a wearer; a first knob disposed on the body; a first length member connected to the first knob; a length adjustment member disposed spaced apart from the body along the length direction of the first length member; and a second length member connected to the length adjustment member; wherein the length of the first length member is adjusted by operating the first knob, and the length of the second length member is adjusted by operating the length adjustment member.

[0009] In one embodiment of the present invention, the length of the first length member adjusted by operating the first knob may be less than the length of the second length member adjusted by operating the length adjustment member.

[0010] In one embodiment of the present invention, when a wearer wears the mask, the first length member can be disposed on the body without contacting the wearer's face.

[0011] In one embodiment of the present invention, the second length member is disposed in the length direction of the first length member, and the mask may further include: a connecting member, one side of which is connected to the first length member and the other side of which is connected to the second length member.

[0012] In one embodiment of the present invention, the first knob may be disposed in the central part of the body, and the connecting member may be disposed on the side of the wearer's face.

[0013] In one embodiment of the present invention, the length adjustment member may be a buckle.

[0014] In one embodiment of the present invention, the first length member may be a metal wire, and the second length member may be a strap or band.

[0015] In one embodiment of the present invention, the mask may further include: a second knob disposed on the body and adjacent to the first knob on the wearer's chin; and a third length member connected to the second knob; wherein the length of the third length member can be adjusted by operating the second knob.

[0016] In one embodiment of the present invention, the second length member may be connected to one side of the length adjustment member, and the mask may further include a headband connected to the other side of the length adjustment member to surround the wearer's head.

[0017] In one embodiment of the present invention, the mask may further include a fourth length member connected to the body and the headband.

[0018] Invention Effects

[0019] In one embodiment of the mask of the present invention, the wearer operates a knob on the main body to adjust the length of the first length member, thereby temporarily removing the mask for a short rest without completely removing it. The knob operation is simple and easy for the wearer, allowing for quick and efficient removal and re-wearing of the mask. Therefore, the wearer can shorten the time required to remove and re-wear the mask, thus minimizing the time spent exposed to harmful substances.

[0020] Additionally, the mask may include a length adjustment member for adjusting the length of the second length member, which the wearer can operate to adjust the length of the second length member so that the mask can be completely removed.

[0021] On the other hand, the operation of the knob and the length adjustment component can be independent of each other. Therefore, the wearer can remove the mask for a short rest by operating the knob, and can completely remove the mask from the face by operating the length adjustment component. As a result, the wearer can choose to operate either the knob or the length adjustment component to perform the desired operation, thus improving the mask's convenience. Attached Figure Description

[0035] Figure 1 and Figure 2 These are a front view and a perspective view of a face mask according to one embodiment. Figure 3 It indicates that the wearer is wearing Figure 2 A three-dimensional image showing the situation of the face mask.

[0036] Reference Figures 1 to 3 The face mask 10 may include a body 100, a first knob 120, a first length member 130, a second length member 140, and a first length adjustment member 160. In addition, the face mask 10 may also include a first connecting member 140 and a headband 170.

[0037] The body 100 can be disposed on the wearer's face. In an exemplary embodiment, the body 100 can cover the lower part of the wearer's face, i.e., the mouth and nose.

[0038] The body 100 may include a contact portion 101, a support portion 102, and a cover portion 104.

[0039] The contact portion 101 can contact the wearer's face. In an exemplary embodiment, the contact portion 101 may be made of rubber material, so that it can fit snugly against the wearer's face and prevent harmful external substances from entering the wearer's mouth and nose.

[0040] The support portion 102 can be integrated with the inner surface of the contact portion 101 and cover the wearer's mouth and nose, configured to be separated from the wearer's face. In an exemplary embodiment, the support portion 102 can be made of plastic or metal, thus supporting the shape of the contact portion 101. That is, the support portion 102 can support the shape of the contact portion 101 so that the contact portion 101 does not obstruct the wearer's mouth and nose, allowing the wearer to breathe smoothly. In one embodiment, a portion of the support portion 102 can extend through the contact portion 101 and protrude to the outside. A protrusion 103 can be provided on the outside of the support portion 102, allowing the wearer to finely adjust the position of the mask 10 while wearing it.

[0041] The cover 104 may be disposed outside the contact portion 101 and the support portion 102. The cover 104 may support the first knob 120 and cover a portion of the first length member 130. In an exemplary embodiment, the cover 104 may be made of plastic or metal.

[0042] The filter 110 is disposed on the side of the body 100 and can filter harmful substances contained in the air when the wearer inhales the air. In an exemplary embodiment, the filter 110 may be detachably disposed on the side of the support portion 102.

[0043] The filter 110 may have an external inlet 111 through which the wearer inhales air. An internal component (not shown) is provided inside the filter 110, through which harmful substances contained in the air entering the filter 110 through the inlet 111 can be filtered. Therefore, the wearer can inhale air filtered by the filter 110.

[0044] On the other hand, an exhaust port 105 may be provided at the lower part of the cover 104, through which the wearer can expel air.

[0045] That is, the wearer can inhale air filtered of harmful substances through the filter 110 and exhale air through the outlet 105, thereby breathing.

[0046] The first knob 120 can be positioned at the center of the cover 104. One end of the first length member 130 can be connected to the first knob 120, and the length of the first length member 130 can be adjusted by operating the first knob 120. That is, when the wearer is wearing the mask, one end of the first length member 130 can be wrapped around the first knob 120, and when the wearer removes the mask, one end of the first length member 130 can be released from the first knob 120 (see reference). Figure 4aTherefore, the length of the first length member 130 can be adjusted. The specific details of adjusting the length of the first length member 130 by operating the first knob 120 will be described in detail later.

[0047] Two first length members 130 may be provided, each of which may be connected to a first knob 120 provided in the center of the cover 104 and extend toward the side of the wearer's face.

[0048] on the other hand, Figures 1 to 3 The illustration shows a configuration where a first knob 120 is located at the center of the cover 104, and two first length members 130 are respectively connected to the first knob 120. However, the invention is not necessarily limited to this configuration. Two first knobs 120 may be provided in the cover 104, each first knob 120 may be located on a side of the cover 104, and each first length member 130 may be connected to an adjacent first knob 120.

[0049] In an exemplary embodiment, a portion of the first length member 130 may be disposed on the contact portion 101 and covered by the cover portion 104. In one embodiment, the first length member 130 may be, for example, a metal wire. In one embodiment, the first length member 130 may not contact the wearer's face.

[0050] The other end of the first length member 130 can be connected to one side of the first connecting member 140. The first connecting member 140 can be disposed on the side of the wearer's face.

[0051] The second length member 150 can be disposed along the length of the first length member 130. One end of the second length member 150 can be connected to the other side of the first connecting member 140. That is, the first length member 130 is connected to one side of the first connecting member 140, and the second length member 150 is connected to the other side of the first connecting member 140, so the first length member 130 and the second length member 140 do not need to be directly connected to each other. Therefore, by operating the first knob 120, the length of the first length member 130 can be adjusted without adjusting the length of the second length member 150, the details of which will be described in detail later.

[0052] The second length member 150 may include a first portion 150a adjacent to the wearer's face and a second portion 150b separated from the wearer's face.

[0053] In one embodiment, the second length member 150 may be, for example, a strap or band. In one embodiment, the second length member 150 may contact the wearer's face.

[0054] The other end of the second length member 150 can be connected to one side of the first length adjusting member 160. The first length adjusting member 160 can be spaced apart from the body 100 and disposed in the length direction of the first length member 130. In one embodiment, the first length adjusting member 160 can be, for example, a buckle, and a first rod 161 can be provided on one side of the first length adjusting member 160.

[0055] The length of the second length member 150 can be adjusted by operating the first length adjustment member 160. That is, the wearer operates the first length adjustment member 160 to adjust the length of the second portion 150b of the second length member 150, thereby allowing the wearer to put on and take off the face mask 10 (see reference). Figure 5a The specific details of adjusting the length of the second length member 150 by operating the first length adjustment member 160 will be described in detail later.

[0056] The headband 170 can be attached to the other side of the first length adjustment member 160 and surround the wearer's head. In an exemplary embodiment, the headband 170 can surround the sides, front, and back of the head.

[0057] In an exemplary embodiment, the headband 170 portion surrounding the front of the head may include connecting holes 171 and connecting protrusions 172. Multiple connecting holes 171 may be provided, and the wearer can adjust the length of the headband 170 according to the wearer's head size by connecting the connecting protrusions 172 to the desired connecting holes 171.

[0058] In an exemplary embodiment, for the comfort of the wearer, the headband 170 may be made of, for example, a padded material.

[0059] Figure 4a and Figure 4b It indicates that the wearer has removed the garment. Figure 3 face mask and wearing Figure 3 A three-dimensional image showing the situation of the face mask.

[0060] Reference Figure 4a The wearer can raise or lower the first knob 120 to remove the face mask 10. Specifically, if the wearer raises or lowers the first knob 120, one end of the first length member 130, which was originally wrapped around the first knob 120, can be unwound from the first knob 120. Therefore, the first length member 130 can be stretched to a maximum length L1. That is, the wearer can remove the face mask 10 by raising or lowering the first knob 120 to stretch the length of the first length member 130.

[0061] In an exemplary embodiment, even if the first length member 130 is stretched to the first length L1, the mask 10 will not completely detach from the wearer's face, and therefore the mask 10 will not be removed from the wearer's face.

[0062] Reference Figure 4b The wearer can rotate the first knob 120 to wear the mask 10. Specifically, if the wearer rotates the first knob 120, one end of the first length member 130 can be wrapped around the first knob 120, thus reducing the first length member 130 by a maximum of a first length L1. That is, the wearer can wear the mask 10 by rotating the first knob 120 to reduce the length of the first length member 130.

[0063] Reference Figure 5a After opening the first lever 161 of the first length adjustment member 160, the wearer can pull the first portion 150a of the second length member 150 towards the body 100 in a first direction away from the wearer's face to remove the face mask 10. At this time, the first portion 150a can be extended up to the second length L2, and the second portion 150b can be reduced up to the second length L2. In an exemplary embodiment, the second length L2 can be longer than the first length L1.

[0064] In an exemplary embodiment, if the first portion 150a is stretched to the second length L2, the mask 10 can be completely detached from the wearer's face, and thus the mask 10 can be completely removed from the wearer's face.

[0065] Reference Figure 5b After the wearer opens the first lever 161 of the first length adjustment member 160, the second part 150b of the second length member 150 can be pulled in the first direction to wear the mask 10. At this time, the first part 150a can reduce the second length L2 at most, and the second part 150b can extend the second length L2 at most.

[0066] After the wearer adjusts the length of the second length member 150, in order to prevent the second length member 150 from detaching from the first length adjustment member 160 or from changing its length, the first rod 161 can be closed, so that the second length member 150 can be fixed by the first length adjustment member 160.

[0067] on the other hand, Figures 4a to 5b The illustration shows a scenario where the wearer independently operates the first knob 120 and the first length adjustment member 160 to put on or take off the face mask 10. Although the description is based on this, the invention is not necessarily limited thereto. The wearer may operate the first knob 120 and the first length adjustment member 160 simultaneously to put on or take off the face mask 10.

[0068] As previously described, the wearer can operate the first knob 120 to adjust the first length member 130, thereby putting on or taking off the mask 10. In this case, the first length member 130 can be adjusted accordingly to the first length L1 by operating the first knob 120, and even if the first length member 130 is lengthened by the first length L1, the mask 10 will not be removed from the wearer's face. That is, the wearer can adjust the length of the first length member 130 by operating the first knob 120, thereby taking off the mask 10, but without removing it from the wearer's face.

[0069] While wearing mask 10, the wearer may need to temporarily remove it for short breaks such as breathing freely, talking, making phone calls, or drinking water. At this time, the wearer can raise or lower the first knob 120 to remove the mask 10, and after a short rest, rotate the first knob 120 again to put the mask 10 back on. The operation of the first knob 120 is simple and easy for the wearer, allowing for quick and efficient removal and re-wearing of the mask 10. Therefore, the wearer can shorten the time spent removing and re-wearing the mask 10, thus minimizing the time spent exposed to harmful substances.

[0070] Alternatively, the wearer can operate the first length adjustment member 160 to adjust the second length member 150, thereby putting on or taking off the mask 10. In this case, by operating the first length adjustment member 160, the first portion 150a of the second length member 150 can be adjusted accordingly to the second length L2. At this time, the second length L2 can be longer than the first length L1. If the first portion 150a is stretched to lengthen the second length L2, the mask 10 can be completely removed from the wearer's face. That is, the wearer can operate the first length adjustment member 160 to adjust the length of the first portion 150a, thereby removing the mask 10.

[0071] Furthermore, the first length member 130 is connected to one side of the first connecting member 140, and the second length member 140 is connected to the other side of the first connecting member 140. Therefore, the length adjustment action of the first length member 130 based on the first knob 120 and the length adjustment action of the second length member 150 based on the first length adjustment member 160 can be performed independently of each other. In other words, when the wearer operates the first knob 120 to adjust the length of the first length member 130, the length of the second length member 150 will not be adjusted; when the wearer operates the first length adjustment member 160 to adjust the length of the second length member 150, the length of the first length member 130 will not be adjusted.

[0072] That is, the mask 10 may include a first knob 120 and a first length adjustment member 160, the operation of which can be independent of each other. Therefore, the wearer can remove the mask 10 for a short rest by operating the first knob 120, and can completely remove the mask 10 from the face by operating the first length adjustment member 160. As a result, the wearer can choose to operate either the first knob 120 or the first length adjustment member 160 to perform the required operation, thus improving the convenience of the mask 10.

[0073] Figure 6 This is a perspective view illustrating a face mask according to an embodiment of the present invention. The face mask includes components similar to those referenced. Figures 1 to 5b The compositions described are substantially the same or similar, so repeated parts will not be repeated.

[0074] Reference Figure 6 The face mask 10 may include a body 100, a first knob 120, a second knob 180, a first length member 130, a second length member 140, a third length member 190, a fourth length member 210, a first length adjustment member 160, and a second length adjustment member 220. Additionally, the face mask 10 may also include a first connecting member 140, a second connecting member 200, and a headband 170.

[0075] The first knob 120 can be mounted on the upper center of the cover 104.

[0076] The second knob 180 may be located at the lower center of the cover 104. In an exemplary embodiment, the second knob 180 may be disposed adjacent to the first knob 120 on the wearer's chin.

[0077] One end of the third length member 190 can be connected to the second knob 180, and the length of the third length member 190 can be adjusted by operating the second knob 180. That is, when the wearer is wearing the mask, one end of the third length member 190 is wrapped around the second knob 180, and when the wearer removes the mask, one end of the third length member 190 can be released from the second knob 180, thereby adjusting the length of the first length member 130.

[0078] On the other hand, the operation of the second knob 180 and the length adjustment action of the third length member 190 based thereon can be substantially the same as the operation of the first knob 120 and the length adjustment action of the first length member 130 based thereon. By operating the second knob 180, the third length member 190 can be adjusted accordingly to a third length. In an exemplary embodiment, the third length can be substantially the same as the first length L1 and can be less than the second length L2.

[0079] In an exemplary embodiment, even if the third length member 190 elongates the third length, the mask 10 will not completely detach from the wearer's face, and therefore the mask 10 will not be removed from the wearer's face.

[0080] Two third length members 190 may be provided, each third length member 190 may be connected to a second knob 180 provided in the lower center of the cover 104 and extend toward the wearer's chin.

[0081] In an exemplary embodiment, a portion of the third length member 190 may be disposed on the contact portion 101 and may be covered by the cover portion 104. In one embodiment, the third length member 190 may be, for example, a metal wire. In one embodiment, the third length member 190 may not contact the wearer's face.

[0082] The other end of the third length member 190 can be connected to one side of the second connecting member 200. The second connecting member 200 can be positioned around the wearer's neck.

[0083] The fourth length member 210 can be configured along the length direction of the third length member 190. One end of the fourth length member 210 can be connected to the other side of the second connecting member 200. That is, the third length member 190 is connected to one side of the second connecting member 200, and the fourth length member 210 is connected to the other side of the second connecting member 200, so the third length member 190 and the fourth length member 210 do not need to be directly connected to each other. Therefore, the length adjustment action of the third length member 190 based on the operation of the second knob 180 and the length adjustment action of the fourth length member 210 based on the second length adjustment member 220 can be performed independently of each other.

[0084] The fourth length member 210 may include a third portion 210a adjacent to the wearer's neck and a fourth portion 210b spaced apart from the wearer's neck.

[0085] In one embodiment, the fourth length member 210 may be, for example, a strap or band. In one embodiment, the fourth length member 210 may contact the wearer's neck.

[0086] The other end of the fourth length member 210 can be connected to the second length adjusting member 220. In one embodiment, the second length adjusting member 220 can be, for example, a male and female buckle, and therefore can include a first female buckle 221 and a first male buckle 222. In addition, a second rod (not shown) can be provided on the first female buckle 221.

[0087] The length of the fourth length member 210 can be adjusted by operating the second length adjustment member 220. That is, the wearer can operate the second length adjustment member 220 to adjust the length of the third part 210a of the fourth length member 210, thereby putting on or taking off the mask 10.

[0088] On the other hand, the operation of the second length adjusting member 220 and the length adjusting action of the fourth length member 210 based thereon can be substantially the same as the operation of the first length adjusting member 160 and the operation of the second length member 150 based thereon. Through the operation of the second length adjusting member 220, the fourth length member 210 can be adjusted accordingly to the fourth length. In an exemplary embodiment, the fourth length can be substantially the same as the second length L2, and can be longer than the first length L1 and the third length.

[0089] In an exemplary embodiment, if the first portion 150a of the second length member 150 is stretched to the second length L2, and the first portion 210a of the fourth length member 210 is stretched to the third length, then the mask 10 can be completely removed from the wearer's face.

[0090] Figure 6 The illustration shows a case where only the portion of the fourth length member 210 connected to the first female buckle 221 includes the fourth portion 210b, but the invention is not necessarily limited to this. It is also possible that only the portion of the fourth length member 210 connected to the first male buckle 222 includes the fourth portion 210b, or that the portions of the fourth length member 210 connected to the first female buckle 221 and the portions of the fourth length member 210 connected to the first male buckle 222 each include the fourth portion 210b.

[0091] Furthermore, although the description describes the case where the second rod is provided only in the first female buckle 221, the present invention is not necessarily limited to this. It is also possible that the second rod is provided only in the first male buckle 222 or that the second rod is provided in both the first female buckle 221 and the first male buckle 222.

[0092] As previously mentioned, the lifting and rotating operations of the first knob 120 or the second knob 180 are simple and easy for the wearer, allowing the wearer to quickly and efficiently remove and put on the mask 10. Therefore, the wearer can reduce the time spent removing and putting on the mask 10, thus minimizing the time spent exposed to harmful substances.

[0093] In addition, the second knob 180, the third length member 190, the fourth length member 210 and the second length adjustment member 220 can be configured on the wearer's chin and neck to further improve the fit between the wearer's face and the mask 10, thereby further improving the mask 10's ability to block harmful substances.

[0094] Figure 7 and Figure 8 This is a perspective view illustrating a face mask according to an embodiment of the present invention. The face mask includes components similar to those referenced. Figures 1 to 5b The compositions described are substantially the same or similar, so repeated parts will not be repeated.
