    BRIEF DESCRIPTION OF THE DRAWINGS



    [0012] 

    Figure 1 is a stereoscopic structural diagram of a heat conducting mechanism according to the disclosure.

    Figure 2 is a front view of the heat conducting mechanism according to the disclosure.

    Figure 3 is a stereoscopic diagram of a personal care device made by using the heat conducting mechanism.


    DETAILED DESCRIPTION



    [0013] The disclosure is further explained below in conjunction with the drawings.

    [0014] Referred to Figures 1 and 2, the disclosure includes a heat conductor 2 and a mounting rack 1, wherein, the heat conductor 2 is fixedly mounted on the mounting rack 1, and wherein, the heat conductor 2 is an aluminum plate, and, according to the invention, a bamboo fiber layer 3 or, not according to the invention, a carbon fiber layer 3 is arranged at a working face of the heat conductor 2. The bamboo fiber layer or the carbon fiber layer 3 is laid at the working surface of the heat conductor 2, allowing a part in contact with hair in a working process to be the bamboo fiber layer or a carbon fiber layer.

    [0015] The bamboo fiber layer or the carbon fiber layer 3 and the heat conductor 2 are independent respectively, and the bamboo fiber layer or the carbon fiber layer 3 is matched with the heat conductor 2 in an insertion way. Cone-shaped grooves are formed at the surface of the heat conductor 2, two sides of the bamboo fiber layer or the carbon fiber layer 3 are fitted with the cone-shaped grooves, and the bamboo fiber layer or the carbon fiber layer 3 is inserted into the cone-shaped grooves. The bamboo fiber layer or the carbon fiber layer 3 may also be fixed to the heat conductor 2 in a sticking way, only if it is ensured that the bamboo fiber layer or the carbon fiber layer 3 can not drop down.

    [0016] Convex clamping blocks 4 are arranged on inner topper sides of a groove of the mounting rack 1, concave grooves fitted with the clamping blocks 4 are arranged at the outer surface of the heat conductor 2. The clamping blocks 4 are clamped in the concave grooves of the heat conductor 2, so that the heat conductor 2 is fixed in the mounting rack 1 and a phenomenon that the heat conductor 2 drops down is prevented from occurring.

    [0017] A surface of the bamboo fiber layer or the carbon fiber layer 3 is higher than the surface of the heat conductor 2, and the bamboo fiber layer or the carbon fiber layer 3 has elasticity. Therefore, in a tightly holding process, in the case that the surface of the bamboo fiber layer or the carbon fiber layer 3 is higher than the surface of the heat conductor 2, the bamboo fiber layer or the carbon fiber layer 3 allows a position which is held tightly to be tighter and allows holding or perming of hair to be better in effect.

    [0018] Bamboo fibers are of cellulosic fibers extracted from a bamboo growing naturally. The bamboo fibers have properties of good breathability, instant water absorption, stronger wear resistance and the like, and also have the functions of natural antibiosis, bacteriostasis, mite removal, deodorizing and ultraviolet ray resistance. Experts point out that the bamboo fibers are of natural environment-friendly green fibers in the real sense, and the bamboo fibers have high-quality inverse elasticity, wear resistance, and flame resistance. The natural bamboo fibers can absorb water which is 20 percentage of weight of themselves, are highest in water absorption among other fiber fabric of the same density, and have excellent inverse elasticity and flame resistance.

    [0019] The bamboo fibers and the aluminum plate are combined, that is, the advantages that the aluminum plate is easy to form, low in machining requirements and low in material cost are utilized. The bamboo fibers are used at the surface of the aluminum plate, also the advantages that the bamboo fibers have high strength, moderate elasticity modulus, good heat resistance, light weight, wear resistance and the like are utilized, and the heat conducting mechanism is allowed to be more resistant to heat and have no deformation.

    [0020] Referred to Figure 3, a personal care device using the heat conducting mechanism includes a pair of holding components, tails of which are hinged, wherein, the heat conducting mechanism is arranged inside the holding components, a heating body is embedded in the heat conducting mechanism, and the heat conducting mechanism is in contact with the heating body. Through using the heat conducting mechanism where the bamboo fiber layer 3, according to the invention, or the carbon fiber layer 3, not according to the invention, and the aluminum plate are combined, and through allowing the bamboo fiber layer or the carbon fiber layer 3 to be the working face, the defects that the aluminum plate has no heat resistance and no wear resistance in the past are solved.

    [0021] The embodiments should not be regarded as limitation of the disclosure, as long as this falls within the scope of the claims.
