DETAILED DESCRIPTION

[0036] In the following, the utility model is further described in combination with the drawings and specific embodiments, and it should be explained that, under the premise of not conflicting, the following described each embodiment or each technical feature can be combined to form a new embodiment.

[0037] Reference Figures 1 to 15 :

[0038] The utility model discloses a face mask face sticking device, reference Figure 2 , Figure 3The face-adhering end 10A of the face-adhering device 100 is made of soft material, which is preferably sponge, soft rubber, or the like, or is wrapped with PU cloth. The overall shape of the face-adhering device 100 includes an upper edge portion 110, a side edge portion 120, and a bottom edge portion 130, which together form a face-adhering shape that fits the contour of a human face. The face-adhering shape is designed to fit the shape of a human face from the forehead to the side of the forehead and the upper part of the nose, so that the upper edge portion 110 is concave forward, the integrally formed side edge portion 120 is concave backward, and the bottom edge portion 130 is concave forward and extends. In order to achieve ventilation, the face-adhering device 100 is provided with a wind channel assembly 3 on the side close to the face-adhering end 10A. The wind channel assembly 3 is arranged on the upper edge portion 110 or the side edge portion 120 of the face-adhering device 100 and penetrates one side of the face-adhering device 100 to help form a ventilation structure on both sides of the face mask 1000. In this case, it is preferable to penetrate the side of the face-adhering device 100 on the face-adhering end 10A, so that it is aligned with the forehead to form ventilation. In other embodiments, the penetration position can also be on the side away from the face-adhering end 10A, or in the form of a ventilation hole.

[0039] Reference Figure 3 , Figure 4 The wind channel assembly 3 includes an upper forehead wind channel 31 and a side forehead wind channel 32. The upper forehead wind channel 31 is arranged on the upper edge portion 110 of the face-adhering device 100 corresponding to the upper end of the nose bridge, and the side forehead wind channel 32 is arranged on the upper edge portion 110 or the side edge portion 120 of the face-adhering device 100 corresponding to the oblique upper end of the eye corner. Both the upper forehead wind channel 31 and the side forehead wind channel 32 penetrate from top to bottom on the side of the face-adhering device 100 on the face-adhering end. Even if the face is close to the face-adhering device 100, the wind can still pass through the wind channel assembly 3, ensuring ventilation on both sides of the face mask 1000. The inside of the face mask 1000 refers to the internal cavity wrapped by the face mask 1000 when a person uses the face mask 1000. The upper end of the internal cavity is made airtight to achieve light-blocking properties, which can easily cause stuffiness and water vapor. In summer, sweating is also common. Although individual head-mounted products have a fan 2001, the fan 2001 cannot blow down from the upper end. By arranging the face-adhering device 100, the above problems can be perfectly solved. Figure 9 As shown in FIG. 10, the face-adhering device 100 is applied to a head-mounted device 2000, which has a fan 2001. The wind of the fan 2001 blows downward from the forehead (as shown by the dashed arrow in the figure), and the wind can enter the internal cavity of the face mask 1000 through the wind channel assembly 3 and be discharged downward through the nose holder 7 of the face mask 1000, thereby forming a convection that removes internal water vapor and heat. Figure 1 Figure 6 ​、 Figure 7 and Figure 8 As shown in FIG. 1 1, the face sticking device 100 is applied to a mask 1000 without a fan 2001, but due to the design of the air slot assembly 3, air can also form up and down convection, only the wind speed is slower, and the technical problem can still be solved.

The upper forehead air slot 31 and the side forehead air slot 32 penetrate the top layer 101, so that the top layer 101 has a thick compression space to improve the comfort of the face sticking end 10A. As a daily production, the top layer 101 is generally filled with soft material as a filler, such as sponge. Even if the sponge is compressed to the extreme, it still has a certain thickness, so the gap of the air slot assembly 3 is still retained.

[0043] Referring to Figure 5As an optional embodiment, the face sticking device 100 comprises a top layer 101, a middle layer 102 and a base layer 103, wherein the base layer 103 is located at the bottommost position and forms the bottom groove part 10B, the middle layer 102 is located at the middle position, and the top layer 101 is located at the upper end of the middle layer and forms the face sticking end 10A, the layers of the base layer 103, the middle layer and the top layer 101 are bonded by glue to prevent lateral displacement between the layers, and the upper forehead air groove 31 and the side forehead air groove 32 penetrate the top layer 101 and the middle layer, as an optimization, the base layer 103 and the middle layer 102 are made of hard materials such as hard plastic, hardboard and the like, so as to ensure that the top layer 101 will not be compressed after the top layer 101 is compressed, so that the air groove assembly 3 still has sufficient gap ventilation, and the top layer 101 is made of soft materials such as sponge or soft glue to increase the comfort of the face sticking, and as a subsequent improved embodiment, each layer can also be made in the form of cloth wrapping the contents.

The diameter of the top-in position slot 821 is greater than that of the bottom shaft rotating slot 822. The top-in position slot 821 is used for the shaft buckle part 812 of the rotating buckle 81 to enter. The bottom shaft rotating slot 822 is used for rotating cooperation with the shaft buckle part 812. When the shaft buckle part 812 is inserted into the top-in position slot 821 and then buckled downward, it can enter the bottom shaft rotating slot 822. The bottom shaft rotating slot 822 is an inner groove with a circumferential annular surface. After the shaft buckle part 812 is inserted into the bottom shaft rotating slot 822, it functions as a rotating shaft, so that the soft rubber part 4 with soft material has a certain deformation property. When the user feels uncomfortable, the face mask 1000 can be adjusted up, down, left, right, forward and backward. When the face mask 1000 is adjusted, the face is first against the face device 100, and the face device 100 is directly connected with the soft rubber part 4. Therefore, the soft rubber part 4 has a slight deformation relative to the shell 5. This deformation is called self-adaptive deformation. The both sides of the shaft joint part 811 are provided with a let-in slot 811b, so that the shaft joint part 811 has an extension trunk 811a which is not interfered by the both sides.
