In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0024] See also Figure 1-2 The first aspect of the utility model provides a connection structure for connecting a headband to a mask, comprising: a fixing structure 1 and a connecting member 2, wherein the fixing structure 1 is arranged on the peripheral side of the mask body, the connecting member 2 comprises a connecting member 2 body, a first end 21 and a second end 22, the first end 21 and the second end 22 are respectively connected to the two ends of the connecting member 2 body; the first end 21 is rotatably connected to the fixing structure 1, and when the first end 21 and the fixing structure 1 are in a preset angle relationship, the first end 21 can be disassembled and assembled with the fixing structure 1; the second end 22 is used for detachably connecting with the headband.
[0025] The connection structure of the utility model includes a fixing structure 1 and a connecting member 2, wherein the fixing structure 1 is arranged on the mask body, and the connecting member 2 includes a connecting member 2 body, a first end 21, and a second end 22. The first end 21 is assembled on the fixing structure 1, so that the connection between the connecting member 2 and the mask body can be realized, and the second end 22 can be detachably connected to the headband, so that when the second end 22 is connected to the headband, the connection between the connecting member 2 and the headband can be realized, so the headband can be connected to the mask body through the connecting member 2. The first end 21 is rotatably connected to the fixing structure 1, and when the first end 21 and the fixing structure 1 are in a preset angle relationship, the first end 21 can be assembled on the fixing structure 1, or the first end 21 can be disassembled from the fixing structure 1. Therefore, when disassembling, after rotating the first end 21 and the fixing structure 1 to a preset angle, the connecting member 2 and the fixing structure 1 can be separated, so that the headband can be easily disassembled from the mask body and then cleaned and disinfected; when assembling, after the first end 21 and the fixing structure 1 are in a preset angle relationship, the connecting member 2 can be fixed to the fixing structure 1, so that the headband can be easily assembled to the mask body and then put into use. Therefore, the utility model has the advantages of being simple and reliable, easy to install and disassemble, and can improve the user experience.
[0026] It should be understood that during the cleaning and disinfection process, there is no limit on the cleaning time of the connector 2. Therefore, you can choose not to disassemble the connector 2 and the headband. The connector 2 and the headband can be cleaned together, or they can be disassembled and then cleaned. Therefore, the assembly relationship between the connector 2 and the headband does not affect the disassembly and assembly process of the entire mask.
[0027] Furthermore, in this embodiment, the fixing structure 1 includes a first fixing column 11 arranged on the mask body, and the first end 21 includes a first limiting ring 211 connected to the main body of the connecting member 2, and the first limiting ring 211 is sleeved outside the first fixing column 11 and can be rotatably connected to the first fixing column 11; the first limiting ring 211 opens a first notch 212, and the first notch 212 is used to separate the first limiting ring 211 and the first fixing column 11.
[0028] Specifically, the first limiting ring 211 is sleeved on the outside of the first fixed column 11. By rotating the connecting piece 2 or the mask body, the first limiting ring 211 and the first fixed column 11 can be rotated relative to each other. When the first limiting ring 211 and the first fixed column 11 are in a preset angle relationship, the user can pull the first fixed column 11 out of the first limiting ring 211 through the first notch 212, thereby realizing the separation of the first fixed column 11 and the first limiting ring 211, and the separation of the connecting piece 2 and the mask body can be realized, and the rotation and pulling processes are relatively easy and convenient. Therefore, the utility model has the advantages of being simple and reliable, easy to install and disassemble, and can improve the user experience.
[0029] In other embodiments, the fixing structure 1 includes a second limiting ring arranged on the mask body, the first end 21 includes a second fixing column connected to the connecting member 2 body, the second limiting ring is sleeved outside the second fixing column and can be rotatably connected to the second fixing column; the second limiting ring has a second notch, and the second notch is used to separate the second limiting ring and the second fixing column.
[0030] It should be understood that the first limiting ring 211 can be equivalent to the second limiting ring, and the first fixing column 11 can be equivalent to the second fixing column, that is, the first limiting ring 211 and the second limiting ring can have exactly the same structure, the first fixing column 11 and the second fixing column can have exactly the same structure, and the first limiting ring 211 and the first fixing column 11, as well as the second limiting ring and the second fixing column have the same assembly relationship. The difference is that the first limiting ring 211 is integrally arranged or separately connected with the connecting member 2 body, and the first fixing column 11 is integrally arranged or separately connected with the mask body; while the second limiting ring is integrally arranged or separately connected with the mask body; and the second fixing column is integrally arranged or separately connected with the connecting member 2 body. Of course, in some embodiments, the structures of the first limiting ring 211 and the second limiting ring can be different, and the structures of the first fixing column 11 and the second fixing column can also be different, such as the connecting column 12 of the first fixing column 11 is different from the connecting block of the second fixing column, such as the connecting surface 112 of the first limiting ring 211 is different from the connecting surface 112 of the second limiting ring, and so on.
[0031] Furthermore, a first arc surface 213 is set on the inner side of the first limiting ring 211, and two opposite second arc surfaces 111 are set on the outer side of the first fixing column 11. The second arc surface 111 can be attached to the first arc surface 213, and the arc length corresponding to the first arc surface 213 is greater than the sum of the arc lengths corresponding to the two second arc surfaces 111.
[0032] Specifically, the transverse cross-sectional shape of the first limiting ring 211 can be four-fifths of a circle, or three-quarters of a circle, or five-sixths of a circle, or six-sevenths of a circle, etc., so that it can be extended to form the first arc surface 213, and the first notch 212 is composed of the arc missing in the circle. The circle where the arc corresponding to the first arc surface 213 is located and the circle where the arc corresponding to the second arc surface 111 is located can be concentric circles, or they can be non-concentric circles. It is only necessary to ensure that the second arc surface 111 can fit the first arc surface 213. Therefore, when the first limiting ring 211 and the first fixing column 11 rotate relative to each other, the first arc surface 213 can rotate back and forth between the two second arc surfaces 111. Therefore, when the mask body is relatively stationary, the connector 2 connected to the mask body can be rotated, so that the position of the headband connected to the connector 2 can be adjusted, which can facilitate the user to wear the mask.
[0033] Furthermore, the outer side of the first fixed column 11 also includes two connecting surfaces 112 connected between the two second curved surfaces 111 and arranged opposite to each other, at least part of the connecting surface 112 is located in the first limiting ring 211, and the first limiting ring 211 includes a third end and a fourth end arranged opposite to each other, and a first notch 212 is formed between the third end and the fourth end; assuming that the maximum vertical spacing between the third end and the fourth end is D1, the minimum vertical spacing between the third end and the fourth end is D2, the minimum vertical spacing between the two second curved surfaces 111 is D3, and the maximum vertical spacing between the two connecting surfaces 112 is D4, the following relationship is satisfied: D1<D3, D2≥D4.
[0034] Specifically, the side of the first fixing column 11 also has two connecting surfaces 112 arranged opposite to each other. The maximum vertical spacing between the two connecting surfaces 112 is less than or equal to the minimum vertical spacing between the third end and the fourth end. Therefore, when the notch is rotated to be parallel to the vertical line connecting the two connecting surfaces 112, the mask body or the connecting member 2 can be pulled to make the mask body or the connecting member 2 move relatively. At this time, the first fixing column 11 can be pulled out of the first limiting ring 211 through the first notch 212, so that the connecting member 2 and the mask body can be easily separated. Since the minimum vertical spacing between the two second curved surfaces 111 is greater than the maximum vertical spacing between the third end and the fourth end, when the notch is rotated to be parallel to the vertical line connecting the two second curved surfaces 111 or other positions (the notch is not parallel to the vertical line connecting the two connecting surfaces 112), no matter how the connecting member 2 or the mask body is pulled, the two will not be separated, and the stable assembly of the two can be achieved.
[0035] It should be understood that the vertical spacing refers to the spacing between points at corresponding positions of two relatively arranged surfaces; the third end and the fourth end can be arc surfaces, vertical planes or inclined planes, etc. In actual situations, the sizes of the third end and the fourth end are generally small. Therefore, the maximum vertical spacing and the minimum vertical spacing between the third end and the fourth end are not much different and can be ignored; in addition, for D2>D4, the maximum vertical spacing between the two connecting surfaces 112 should be slightly smaller than the minimum vertical spacing between the third end and the fourth end.
[0036] Further, both connecting surfaces 112 are planes; or, one of the connecting surfaces 112 is the third curved surface, and the other connecting surface 112 is a plane; or, both connecting surfaces 112 are the third curved surface. Specifically, the utility model does not make any specific settings for the setting structure of the connecting surface 112, which can be a plane, a curved surface, a curved surface or other irregular surfaces, and for the curved surface, one connecting surface 112 can be bent toward the other connecting surface 112, or one connecting surface 112 can be bent in a direction away from the other connecting surface 112; for the plane, it can be a vertical plane, or an inclined plane, etc. Since D1>D2, and D1<D3, D2≥D4, it can be known that the minimum vertical spacing between the two second curved surfaces 111 is the largest, and the maximum vertical spacing between the two connecting surfaces 112 is the smallest, and the first curved surface 213 can fit the second curved surface 111, so no matter what the shape of the connecting surface 112 is, it only needs to satisfy D1<D3, D2≥D4. Preferably, both connecting surfaces 112 are vertical planes, which can simplify the manufacturing process.
[0037] Furthermore, the fixed column and the limiting ring extend in the same direction, but the extension length of the fixed column can be less than or greater than or equal to the extension length of the limiting ring. Preferably, the extension length of the first fixed column 11 is greater than or equal to the extension length of the first limiting ring 211. In practical applications, when the fixed column and the limiting ring are relatively rotated, the user usually rotates the connecting member 2 instead of the mask. Therefore, if the extension length of the first fixed column 11 is greater than or equal to the extension length of the first limiting ring 211, when rotating, the user can balance the force between the fixed column and the limiting ring well, so as to rotate better. Similarly, it is preferred that the extension length of the second limiting ring is less than or equal to the extension length of the second fixed column, which has the same technical effect and is not elaborated here.
[0038] Furthermore, in this embodiment, the fixing structure 1 also includes two connecting columns 12 connected to the two ends of the first fixing column 11, and the connecting column 12 is connected to the mask body at one end away from the first fixing column 11. Specifically, the second arc surface 111 and the connecting surface 112 are the side surfaces of the first fixing column 11, and two connecting columns 12 are respectively connected at the two ends perpendicular to the second arc surface 111 and the connecting surface 112, that is, at the top and bottom of the first fixing column 11, and the two connecting columns 12 are connected to the mask body, and a hollow area is formed between the two connecting columns 12, the mask body and the first fixing column 11, so as to facilitate the relative rotation between the first fixing column 11 and the first limiting ring 211.
[0039] In other embodiments, the fixing structure 1 further includes a connecting block protruding from the mask body, and the side of the connecting block facing away from the mask body is connected to the peripheral side of the first fixing column 11. Specifically, the connecting block can be connected to the second arc surface 111, and the extension length of the first fixing column 11 is reduced, which is equivalent to connecting a connecting column 12. Alternatively, the connecting block can be connected to the connecting surface 112, and the first fixing column 11 and the connecting block can form a T-shape, and the projection area of the connecting block on the mask body and on the connecting surface 112 is relatively small. At this time, the arc length corresponding to the first arc surface 213 of the first limiting ring 211 needs to be appropriately reduced, so that the first limiting ring 211 and the first fixing column 11 can rotate within an appropriate range.
[0040] Furthermore, the second end 22 is a trident-shaped structure, which is used for detachable connection with the headband. The headband has an assembly structure matching the trident-shaped structure, so that the headband and the connector 2 can be quickly disassembled. In other embodiments, the headband and the connector 2 can be connected by snap-fit connection, buckle connection, etc. During the cleaning and disinfection process, there is no limit on the cleaning time of the connector 2, so the assembly relationship between the connector 2 and the headband does not affect the disassembly and assembly process of the entire mask.
[0041] The second aspect of the utility model provides a mask, including the above connection structure. The mask body of this embodiment can be connected to the headband through a connector 2. A fixing structure 1 is provided at both ends of the mask body, and it also includes two connectors 2. When disassembling, after the first end 21 and the fixing structure 1 are rotated to a preset angle relationship, the connector 2 and the fixing structure 1 can be separated, so that the headband can be easily removed from the mask body and then cleaned and disinfected; when assembling, after the first end 21 and the fixing structure 1 are in a preset angle relationship, the connector 2 can be fixed to the fixing structure 1, so that the headband can be easily assembled to the mask body and then put into use. Therefore, the utility model has the advantages of being simple and reliable, easy to install and disassemble, and can improve the user experience.
[0042] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
[0043] The above is a description of the technical solution provided by the utility model. For technicians in this field, according to the ideas of the embodiments of the utility model, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the utility model.
