Therefore, the diameter of the pinhole 4 of the above two specifications can allow the clamping piece 6 to be arranged in the cavity. In the body 31.
  • the inner diameter of the cavity 31 matches the outer diameter of the comb needle 1, so that after the comb needle 1 is bent and fitted into the cavity 31, the inner wall of the cavity 31 can exert a force on it. So that its fixing effect is good.
  • a smaller inner diameter of the cavity 31 can make the fixing effect of the comb needle 1 better, but it will increase the difficulty of fitting the hook 5 of the comb needle 1 into the cavity 31, while a larger cavity 31 can reduce It is difficult for the hook 5 of the comb needle 1 to fit into the cavity 31, but it will weaken the fixing effect of the comb needle 1 in the cavity 31; therefore, the relative specifications of the two need to be appropriately set.
  • the hook 5 can be inserted into the cavity 31 together with the clamping piece 6 after it is hooked. This way of assembling the comb needle 1 and the rubber 2 is very easy to implement.
  • the comb needle 1 it is softer than the traditional plastic comb needle to overcome the problem of hair knotting. Therefore, it can be made of nylon yarn or other similar flexible materials, such as nylon with a diameter of 0.7-0.8mm.
  • Silk one end of the comb needle 1 is bent to form a hook 5, and the other end is formed into a spherical or similar shaped comb needle head; the comb needle head can be formed by thermal processing of nylon filament, or attached to the other end of the nylon filament and other materials form.
  • the nylon needle is softer, which can overcome the problem of hair knotting caused by the traditional plastic injection molding needle.
  • the present invention also solves the problem of This brings the problem of fixing the comb needle 1.
  • the thickness of the rubber 2 in the cross-sectional direction gradually increases from the middle to the edge, that is, the thickness of the middle part is smaller than the thickness of the outer edge part of the rubber 2; this way, on the one hand, the middle part of the rubber 2 can be first contacted and deformed. It is the most flexible and enhances the user experience. On the other hand, it can also facilitate the recovery of the rubber 2 after deformation through the gradually increased elastic force. Practice has shown that the uniform thickness of the rubber, in use, there is a small probability that it will not be able to automatically recover. The above-mentioned design of gradually thickening from the middle to the edge can completely avoid this problem.
  • the protruding column 3 and the rubber 2 are integrally formed by injection molding.

It gradually thickens from the center to the outer edge, but The center to the edge does not require uniform thickening; of course, in theory, stepped thickening is also a feasible solution (for example, the overall thickness is divided into three parts of 1.5mm, 2mm and 3mm from the inside to the outside) .
  • the thickness of the rubber skin 1 in principle, it can be specifically selected according to product parameters, materials, etc., but the overall requirement of relative thickness difference must be considered.

  • the rubber 1 is installed in the placement groove 8, and the clamping block 10 is snap-fitted with the clamping groove 9 so that the center of the rubber bulges toward the front.
  • the placement groove 8 of the comb handle 7 of the hair comb of the present invention is arranged to be curved toward the back of the rubber 2, that is, the placement groove 8 is arranged along a curved surface.
  • the hair comb manufactured by this method has an ingenious structure and low overall manufacturing cost, which solves the problem of hair knotting and is easy to clean; at the same time, it completely retains all the functions of the traditional air cushion comb without any reduction.
