Description

Title of the invention: Airbag comb Technical field

[0001] The present invention relates to a type of comb, in particular an airbag comb. Prior art

[0002] The airbag comb uses an air cushion structure, that is, the comb needles are placed on a flexible substrate. This substrate is mounted on a base and has an arcuate and protruding shape. Thus, during combing, with the force applied by the user, the substrate deforms according to the shape of the skull. This allows the comb needles to better adhere to the scalp, avoiding discomfort caused by bony protrusions of the skull. However, rubber combs of this type available on the market are made from cut rubber sheets and then molded to have a certain protrusion. These combs generally have flexibility only in the center, with very little or no flexibility at the edges, and the overall space for flexibility is limited.After a period of use, it is common for the rubber to not be securely fixed, resulting in sagging, which reduces the life of the comb and provides an unsatisfactory user experience. Content of the invention [l]Technical problem to be solved

[0026] Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention will be described in detail.

[0027] Referring to [Fig.l] to [Fig.8], the present invention relates to an airbag comb which comprises an airbag body 2 and a comb body 1.

[0028] In the present application, the surface of the airbag body 2 projects outwardly, forming a cambered working surface 21 capable of undergoing elastic deformation. On this cambered working surface are comb needles 3, used for combing the hair. These needles are arranged in an array on the cambered working surface and follow the curvature of the latter. On the edge of this cambered working surface 21, following its contour, there is an annular clamping part 23. More precisely, the edge of the cambered working surface 21 is provided with a cambered surface 22, the cambered surface 22 is tangent to the cambered working surface, and the radius of the cambered surface 22 is less than the radius of the cambered working surface 21. In this embodiment, the ratio of the radii between the cambered working surface 21 and the cambered surface 22 is 50 to 65.The clamping portion 23 is located on the edge of the cambered surface, together forming a 3D (stereo) structure protruding outward. Between the clamping portion 23 and the lower surface of the cambered working surface 21, a chamber with a lower opening is formed. Between the clamping portion and the cambered surface 22, there is an annular groove 24 with a triangular cross-section.

[0029] In the present application, the airbag body 2 is made of rubber, preferably TPR, and is formed as a single piece by injection molding. The thickness (wall thickness) of the airbag body 2 is greater than or equal to 1mm and less than or equal to 2mm, and the protruding height of the airbag body 2 is greater than or equal to 15mm and less than or equal to 25mm. On the cambered working surface, holes for comb needles are provided for installing the comb needles 3. The comb needles have a general rod shape. On the side wall of their lower end, there is an annular groove which can be fixed inside the holes of the comb needles. The end of the comb needle is provided with a spherical shape.

[0030] The above-mentioned airbag body 2 is circular, elliptical or rectangular in shape with rounded corners.

[0031] The comb body 1 serves as a support and installation structure, and includes a handle 11 made of wood or plastic. On the comb body 1, a mounting groove 10 is formed, having a contour shape similar to that of the clamping portion 23. On the side wall of the mounting groove 10, a snap groove 102 is formed to accommodate and fix the clamping portion 23. In this implementation, the cross-section of the clamping portion is trapezoidal with right angles, as is the cross-section of the snap groove 102. This allows for complete insertion of the clamping portion, providing high installation strength and good sealing. A sealed chamber is formed between the airbag chamber and the mounting groove 10. This sealed chamber provides space for elastic deformation of the cambered working surface.In addition, a ventilation hole is formed on the side wall of the sealed chamber, which serves for the evacuation of air, thus facilitating the deformation of the airbag. This ventilation hole is formed on the airbag body 2, having a diameter greater than or equal to 1.5 mm and less than or equal to 2 mm, ideally 1.8 mm, and in a number of 2 to 3, to increase the elasticity and avoid excessive rigidity.

[0032] The airbag comb of the present invention uses a three-dimensional structure for the airbag, enabling independent prominent support, with good elasticity, superior user comfort, and a long service life. Due to the double-curved design, installation is facilitated, while reducing the overall thickness and ensuring elasticity, which leads to a compact structure, an excellent user experience, and an aesthetic design. The design of the airbag structure provides high flexibility and stable elasticity, avoiding sagging, which ensures user comfort. The airbag comb of this invention is characterized by its compact structure, good elasticity, user comfort, and an excellent user experience.

[0033] The above represents only a preferred embodiment of the present invention. It should be emphasized that for those skilled in the art of this technology, improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be considered as part of the scope of protection of the present invention.
