Description

Heating comb

Technical Field

The utility model relates to the technical field of hair styling devices, in particular to a heating comb.

Background

The prior heating comb has the following technical problems: first, the heating element is because the problem of assembly structure, and a part of heat conduction is to the casing for the casing intensifies, influences user's handheld sensation, and serious probably consequently the casing scalds excessively and the user can't hold, and can make the broach lose a part of heat, and has reduced thermal efficiency, makes the broach intensify slower, and the user needs the waiting time longer. Second, the heating comb has single function. Third, the heating element conducts heat by directly contacting with the comb teeth, but the current heating element is not matched with the comb teeth (in size), that is, the comb teeth have a larger temperature difference (the temperature of the comb teeth close to the heating element is fast, the temperature of the comb teeth far away from the heating element is slow) within a certain time, and the temperature difference is reduced but does not disappear as the time goes longer. Fourth, in the comb assembly, the comb portion and the comb sleeve are in direct contact during assembly, so that heat of the comb portion can be directly conducted to the comb sleeve, and although the comb sleeve is generally made of heat-insulating materials, a small amount of heat still can be conducted to the comb sleeve in a direct conduction mode.

Based on the technical problem, chinese patent publication No. CN211323412U in the prior art discloses a simple and convenient high-efficiency hair straightening comb, which comprises a handle main body, the heating element subassembly joint in the screens, the protection subassembly is established to heating element subassembly lateral wall top cover, the main control board embedding install in the inside wall bottom of bottom one end, left broach and right broach each contact heating plate half area that is heated, the broach adopts the interlude interlock structure about and parallel design reach simultaneously with the heating plate contact make the broach evenly heat, make the hair design be heated evenly, improve the molding effect, and the main control board is with heating plate, temperature sensor cooperation, the main control board makes corresponding adjustment feedback for the heating plate through temperature sensor transmission realize broach group temperature control function, and is automatic stronger, simultaneously, thermal-insulated unsettled protective sheath design and broach group cooperation use, can avoid broach group heat loss and protect scalp and skin and broach group contact, reach constant temperature and thermal insulation effect. Although the above-mentioned prior art directly forms the heat-insulating protection cover on the shell so as to realize direct contact with the comb tooth part and thus avoid direct conduction of heat of the comb tooth group to the heat-insulating protection cover, in practice, the distance between the heat-insulating protection cover and the comb teeth is very close, so that heat of the comb teeth is easily conducted to the heat-insulating protection cover through air, and the heat-insulating protection cover is directly formed on the shell and is easily conducted to the shell, and the comb tooth part is directly fixed on the shell through the supporting legs extending from both ends of the heat-insulating protection cover, that is, the heat of the comb tooth part is directly contacted with the shell, so that the heat of the comb tooth part cannot be prevented from being conducted to the shell through the supporting legs; and the pressing plate is not made of heat insulation materials, so that heat cannot be prevented from being conducted to the shell through the pressing plate, and the shell is heated.

As another chinese patent of the present utility model, the publication number CN208176287U discloses a comb with adjustable pitch, which comprises a comb upper shell, a comb lower shell, a heating comb tooth assembly, a heat insulation assembly, a distance adjusting movable tooth sleeve, a distance adjusting mechanism and a control unit, wherein the comb upper shell and the comb lower shell form a front end which is a heating comb tooth assembly installation cavity, a rear end which is a handle end, and the handle end is provided with the distance adjusting mechanism and the control unit.
