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, meaning that the comb's teeth are placed on a flexible substrate. This substrate is mounted on a base and has an arched, protruding shape. Thus, when combing, with the force applied by the user, the substrate deforms to the shape of the skull. This allows the comb's teeth to adhere better to the scalp, avoiding discomfort caused by bony protrusions of the skull. However, commercially available rubber combs of this type are made from sheets of rubber that are cut 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 properly fixed, resulting in sagging, which reduces the lifespan of the comb and provides an unsatisfactory user experience. Contents of the invention [l]Technical problem to solve

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

[0027] With reference to [Fig.1] to [Fig.8], the present invention relates to an airbag comb which includes an airbag body 2 and a comb body 1.

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

[0029] In the present application, the airbag body 2 is made of rubber, preferably TPR, and is formed in one piece by injection molding. The wall thickness of the airbag body 2 is greater than or equal to 1 mm and less than or equal to 2 mm, and the protruding height of the airbag body 2 is greater than or equal to 15 mm and less than or equal to 25 mm. Holes for comb needles are provided on the curved working surface for installing the comb needles 3. The comb needles have a generally rod-like shape. On the side wall of their lower end, there is an annular groove that can be fixed inside the holes in the comb needles. The end of the comb needle has a spherical shape.

[0030] The airbag body 2 mentioned above 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. A mounting groove 10 is formed on the comb body 1, having a contour similar to that of the clamping part 23. On the side wall of the mounting groove 10, a snap-in groove 102 is formed to receive and secure the clamping part 23. In this embodiment, the cross-section of the clamping part is trapezoidal with right angles, as is the cross-section of the snap-in groove 102. This allows for complete insertion of the clamping part, providing high strength during installation and a good seal. A sealed chamber is formed between the airbag chamber and the mounting groove 10. This sealed chamber provides space for the elastic deformation of the curved working surface.Furthermore, a ventilation opening is formed on the side wall of the sealed chamber, which serves to evacuate air, thus facilitating the deformation of the airbag. This ventilation opening 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 elasticity and avoid excessive rigidity.

[0032] The airbag comb of the present invention uses a three-dimensional structure for the airbag, allowing for independent, prominent support with good elasticity, superior user comfort, and a long service life. Thanks to the double-curvature design, installation is facilitated while reducing the overall thickness and ensuring elasticity, resulting in a compact structure, excellent user experience, and an aesthetically pleasing design. The airbag structure design offers high flexibility and stable elasticity, preventing sagging, which guarantees user comfort. The airbag comb of this invention is characterized by its compact structure, good elasticity, user comfort, and excellent user experience.

[0033] The foregoing 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. Such improvements and modifications shall also be considered as falling within the scope of protection of the present invention.
