Description

Technical Field

[0001] This utility model relates to the technical field of hot air comb equipment, specifically a hot air comb that prevents burns. Background Technology

[0002] A hot air comb is a hair styling tool that combines blow-drying and styling functions. The hot air comb converts electrical energy into heat energy through a built-in heating element to generate hot air. At the same time, the combing action allows the hair to be heated evenly, thus achieving a quick styling effect.

[0003] Existing hot air combs typically blow hot air directly onto the comb barrel via an internal motor and fan, with the hot air exiting directly from ventilation holes on the surface of the comb barrel. This design results in poor heating uniformity of the hot air, leading to uneven temperature distribution of the ejected hot air and affecting the performance of the hot air comb.

[0004] For example, the aforementioned problem exists in patent (CN110464101B); it describes "a hot air comb, comprising a handle and a combing component, wherein the handle and the combing component are hollow structures, the handle has a first air duct, and a fan is provided in the first air duct; the combing component has a second air duct, and the first air duct is connected to the second air duct; the combing component includes a rotating component and a bracket with a support shaft, the support shaft is fixedly connected to one end of the bracket, and the other end of the bracket is connected to the handle; the rotating component includes a comb cylinder and rotating blades, and the..." The outer wall of the comb cylinder has ventilation holes that connect to the inner cavity of the comb cylinder; the rotating blades are rotatably connected to the support shaft, and the airflow generated by the fan passes through the first air duct and enters the second air duct, blowing the rotating blades to rotate. The rotation of the rotating blades drives the comb cylinder to rotate. The hot air comb is driven by hot air, which subverts the function of the current hot air comb. Although the hot air comb in the above patent has rotating blades at the end of the comb cylinder and the rotating blades are fixed to the comb cylinder, the function of the rotating blades is only to drive the comb cylinder to rotate, and the effect on the uniformity of the hot air spray is not good.

[0005] To address the issue that hot air is directly ejected from the ventilation holes on the surface of the comb tube, resulting in poor heating uniformity and consequently poor temperature uniformity of the ejected hot air, thus affecting the performance of the hot air comb, we propose a scald-proof hot air comb. Utility Model Content

[0006] The purpose of this invention is to provide a hot air comb that prevents burns, in order to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a hot air comb to prevent burns, including a handle and a combing component. The combing component is fixedly disposed on the top of the handle. Both the handle and the combing component are hollow structures. The combing component includes a comb tube. A rotatably connected support tube is provided inside the comb tube. A spiral blade is provided on the outer wall of the support tube. A heating component is provided between the inside of the handle and the inner wall of the comb tube.

[0008] Furthermore, the outer wall of the comb tube is provided with a number of ventilation holes and comb teeth, which are arranged alternately.

[0009] Furthermore, the heating assembly includes a heat insulation ring and a mounting ring. The mounting ring is fixedly disposed on the inner wall of the heat insulation ring, and the heat insulation ring is fixedly disposed on the inner wall of the comb near the handle. The inner wall of the mounting ring is provided with a plurality of electric heating wires.

[0010] Furthermore, a support plate is provided on the inner side of the mounting ring, and a first support shaft is vertically provided at the top center of the support plate. The first support shaft is rotatably connected to the bottom of the inner side of the support cylinder through a first bearing.

[0011] Furthermore, a second support shaft is provided on the inner wall of the comb cylinder at the end away from the support plate, and the second support shaft is rotatably connected to the top of the inner side of the support cylinder through a second bearing.

[0012] Furthermore, the electric heating wire is evenly distributed in a ring on the inner wall of the mounting ring.

[0013] Furthermore, the handle is equipped with a motor and a fan, the motor output shaft is connected to the fan in a drive connection, and an air inlet cover is provided at the end of the handle away from the hair comb.

[0014] Furthermore, a control switch is provided on the outer wall of the handle, and a control circuit for a motor and an electric heating wire is provided inside the handle.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] 1. This utility model, by setting up a handle, a comb component, a comb tube, a support tube, spiral blades, and a heating component, allows air to enter the comb tube after being heated by the heating component. After entering the comb tube, the hot air directly impacts the surface of the spiral blades on the outer wall of the support tube. The hot air moves along the spiral blades, and under the impact of the hot air, the spiral blades and the support tube rotate. The spiral blades spirally transport the hot air, causing the hot air to spirally move up and down inside the comb tube. After the hot air is mixed in the spiral motion inside the comb tube, it is discharged from the comb tube. This can effectively improve the mixing uniformity of the hot air inside the comb tube, resulting in better temperature uniformity of the hot air sprayed from the comb tube. This makes the hot air sprayed from the hot air comb more uniform during use, effectively improving the performance of the hot air comb.

[0017] 2. In this utility model, by setting a heat insulation ring in the heating assembly to provide heat insulation on the outside of the mounting ring, the electric heating wire can be effectively insulated. The heat insulation ring and the outer wall of the comb provide double-layer heat insulation for the outside of the electric heating wire, which can effectively prevent burns. The support plate supports the first support shaft on the inside of the mounting ring. The first support shaft and the second support shaft provide rotational support for the support cylinder, which can effectively improve the stability of the support cylinder. At the same time, the above arrangement allows the support cylinder to be located at the upper center of the heating assembly, so that after the hot air passes through the electric heating wire, the hot air can directly impact the surface of the spiral blades, ensuring the normal rotation of the spiral blades.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1-3 This utility model provides a technical solution: a hot air comb to prevent burns, including a handle 1 and a combing component 2. The combing component 2 is fixedly disposed on the top of the handle 1. Both the handle 1 and the combing component 2 are hollow structures. The combing component 2 includes a comb tube 201. A support tube 202 is rotatably connected inside the comb tube 201. A spiral blade 203 is provided on the outer wall of the support tube 202. A heating component 3 is provided between the inside of the handle 1 and the inner wall of the comb tube 201. A plurality of ventilation holes 204 and comb teeth 205 are opened on the outer wall of the comb tube 201. The ventilation holes 204 and comb teeth 205 are staggered. A motor 101 and a fan 102 are provided inside the handle 1. The output shaft of the motor 101 is connected to the fan 102 in a transmission manner. An air inlet cover 103 is provided at the end of the handle 1 away from the combing component 2.

[0028] The working principle of this utility model:

[0029] Refer to the instruction manual appendix Figures 1-3 This utility model comprises a handle 1, a hair comb 2, a comb cylinder 201, a support cylinder 202, spiral blades 203, and a heating component 3. The handle 1 is responsible for handheld operation and air intake. The hair comb 2 is responsible for hair combing and hot combing. The comb cylinder 201 provides rotatable support for the support cylinder 202, allowing the support cylinder 202 to rotate inside the comb cylinder 201. The support cylinder 202 supports the spiral blades 203, which can also rotate inside the comb cylinder 201. The heating component 3 heats the air entering the comb cylinder 201, effectively ensuring that the comb cylinder 201 outputs hot air.

[0030] Air is introduced into the handle 1 and heated by the heating component 3 before entering the comb cylinder 201. The hot air then directly impacts the surface of the spiral blades 203 on the outer wall of the support cylinder 202. The hot air moves along the spiral blades 203, and under the impact of the hot air, the spiral blades 203 and the support cylinder 202 rotate. The spiral blades 203 spirally transport the hot air, causing it to spiral up and down inside the comb cylinder 201. After mixing in this spiral motion, the hot air is discharged from the comb cylinder 201, effectively improving the uniformity of the hot air mixing within the comb cylinder 201. This results in better temperature uniformity of the hot air emitted from the comb cylinder 201, thus improving the overall performance of the hot air comb.

[0031] Ventilation holes 204 provide hot air outlets on the outer wall of the comb barrel 201. The comb teeth 205 are used for combing hair. The ventilation holes 204 and comb teeth 205 are staggered so that hot air can be sprayed onto the hair through the gaps between the comb teeth 205, making the hair more evenly heated. The motor 101 inside the handle 1 drives the fan 102 to rotate. The fan 102 draws outside air from the air inlet cover 103 into the handle 1 and then delivers the air to the comb barrel 201. The air is heated by the heating component 3 and then enters the comb barrel 201.

[0032] Example 2

[0033] Please see Figures 1-5 This utility model provides a technical solution: a scald-proof hot air comb, wherein the heating component 3 includes a heat insulation ring 301 and a mounting ring 302, the mounting ring 302 is fixedly disposed on the inner wall of the heat insulation ring 301, the heat insulation ring 301 is fixedly disposed on the inner wall of the comb tube 201 near the handle part 1, and the inner wall of the mounting ring 302 is provided with a plurality of electric heating wires 303; a support plate 304 is provided on the inner side of the mounting ring 302, and a first support shaft 305 is vertically disposed at the top center of the support plate 304, the first support shaft 305 being rotatably connected to the bottom of the inner side of the support tube 202 through a first bearing; a second support shaft 206 is provided on the inner wall of the comb tube 201 away from the support plate 304, the second support shaft 206 being rotatably connected to the top of the inner side of the support tube 202 through a second bearing; a control switch 104 is provided on the outer wall of the handle part 1, and a control circuit for a motor 101 and electric heating wires 303 is provided inside the handle part 1.

[0034] In one embodiment, the electric heating wires 303 are evenly distributed in a ring on the inner wall of the mounting ring 302. By setting the distribution position and spacing of the electric heating wires 303, the contact uniformity between the hot air entering the comb 201 and the electric heating wires 303 is better, which can effectively improve the heating uniformity of the hot air.

[0035] The working principle of this utility model:

[0036] Refer to the instruction manual appendix Figures 1-5 This utility model provides heat insulation for the electric heating wire 303 by setting a heat insulation ring 301 in the heating component 3 on the outside of the mounting ring 302. The heat insulation ring 301 and the outer wall of the comb 201 provide double-layer heat insulation for the outside of the electric heating wire 303, which can effectively prevent burns. The mounting ring 302 provides an installation position for the electric heating wire 303, and the electric heating wire 303 heats the airflow entering the comb 201.

[0037] The support plate 304 supports the first support shaft 305 inside the mounting ring 302. The first support shaft 305 provides rotational support for the support cylinder 202 through the first bearing, and the second support shaft 206 provides rotational support for the support cylinder 202 through the second bearing, which can effectively improve the stability of the support cylinder 202. At the same time, the above arrangement allows the support cylinder 202 to be positioned above the center of the heating assembly 3, so that after the hot air passes through the electric heating wire 303, the hot air can directly impact the surface of the spiral blade 203, ensuring the normal rotational movement of the spiral blade 203. The control switch 104 is used to turn the control circuit of the motor 101 and the electric heating wire 303 on and off. The control circuit is used to control and adjust the on / off state and speed of the motor 101, and also controls the heating power of the electric heating wire 303. Both the control switch 104 and the control circuit can use mature control components from existing products.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
