Description

Technical Field

[0001] This utility model belongs to the technical field of hair styling tools, specifically a hot air comb. Background Technology

[0002] Hot air combs use hot air to style and set hair. Currently, the heating and blowing components of hot air combs are usually located inside the handle, blowing hot air from inside the handle onto the comb teeth to achieve the function. In existing technology, the hot airflow generated inside the hot air comb is blown directly from the air holes, resulting in a short residence time inside and a fast airflow speed. As a result, much of the heat is dissipated into the external space without being applied to the hair, thus wasting this heat. Utility Model Content

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0036] Please refer to Figure 1-7 ;

[0037] The hot air comb described in this utility model aims to improve heat utilization efficiency. Specifically, it includes a handle 1 and a comb tooth assembly 2. The handle 1 is equipped with a fan 31 and a heating element 32. It also has control components for adjusting the speed of the heating element 32 and the fan 31, etc., to achieve separate control of cold and hot air, etc. The comb tooth assembly 2 includes a heat conduction channel 21, which is installed at the air outlet end of the handle 1. An air cavity 262 is formed inside the heat conduction channel 21. Several sets of heat conduction teeth 221 and several sets of first air outlet holes 23 are distributed on the outside of the heat conduction channel 21. The heat conduction channel 21 and the heat conduction teeth 221 are made of aluminum or aluminum alloy, which has better heat conduction and heat storage performance.

[0038] This embodiment does not limit the distribution of the heat-conducting teeth 221 and the flow guide. For example, a number of heat-conducting teeth 221 may be distributed laterally around the heat-conducting channel 21, or the heat-conducting teeth 221 may be distributed longitudinally at intervals, while a number of first air outlets 23 are always located between two sets of heat-conducting teeth 221. Of course, another implementation is not excluded, in which a set of heat-conducting teeth 221 is provided with a first air outlet 23, that is, the heat-conducting teeth 221 and the first air outlets 23 are distributed alternately, etc.

[0039] Furthermore, there is no limitation on the number of first vent holes 23. Preferably, one vent hole 23 is provided between two heat-conducting teeth 221.

[0040] In use, the heating element 32 and the fan 31 work simultaneously. The fan 31 draws in external air to form an airflow and delivers it towards the heating element 32. After being heated by the heating element 32, the airflow enters the air cavity 262 and heats the heat-conducting passage 21 and the heat-conducting comb teeth (241) through heat transfer. Since the total flow rate output from the several first air outlets 23 is less than the flow rate input by the fan 31, the air pressure in the air cavity 262 will increase, and the airflow velocity output from the several first air outlets 23 will increase. In this embodiment, a guide is provided on several sets of first air outlets 23. It can be understood that a shield is provided above the first air outlets 23. When the hot airflow is ejected from the first air outlets 23, it will come into contact with the guide, so that the airflow will not be directly output to the outside, but will be dispersed to both sides under the action of the guide. This not only slows down the airflow velocity but also prolongs the time that the airflow stays on the comb tooth assembly 2, thus achieving the effect of heat storage and heating.

[0041] Reference Figures 4-6 Further explanation of the flow guide: The flow guide includes several sets of comb teeth (241), each comb tooth (241) corresponding to a first air outlet 23. An empty space 242 communicating with the first air outlet 23 is provided at the root of the comb tooth (241). The comb tooth (241) is made of hard plastic material. After the airflow is output from the first air outlet 23 and reaches the empty space 242, it contacts the inner side of the comb tooth (241) and is divided into two airflows with different directions. In addition, the arrangement of the comb tooth (241) can make up for the empty part formed by the first air outlet 23, making the overall comb tooth (241) more dense and the use effect better. In addition, based on the implementation of the longitudinally spaced distribution of several sets of heat-conducting teeth 221 and several sets of comb teeth (241), the opening direction of the empty space 242 is longitudinal, that is, the upper and lower adjacent empty spaces 242 are interconnected.

[0042] During use, the user's hair will be placed horizontally between the heat-conducting teeth 221 and the comb teeth (241) relative to the heat-conducting passage 21. At this time, the hair is closed on both sides of the clearance position 242, and the two dispersed airflows are output along the direction of the clearance position 242 and act on the hair on both sides, so that the airflow can be fully utilized and fully contact the hair, resulting in a better drying effect.

[0043] In this embodiment of the utility model, reference is made to Figure 5Several sets of heat-conducting teeth 221 and several sets of comb teeth (241) are longitudinally spaced and staggered. Each set of heat-conducting teeth 221 has a first insert plate 222 at its root and each set of comb teeth (241) has a second insert plate 243 at its root. The second insert plate 243 has a third vent hole 244 corresponding to the clearance position 242 and the third vent hole 244 corresponds to the first vent hole 23. The third vent hole 244 on the second insert plate 243 not only allows airflow to flow into the clearance position 242, but also facilitates core pulling and mold opening during production, simplifying the mold structure. Several slots 25 are longitudinally distributed on the surface of the heat-conducting channel 21. The first insert plate 222 and the second insert plate 243 are inserted into the slots 25 and connected to the heat-conducting channel 21. The plug-in method facilitates assembly. Of course, fixing parts should be provided at both ends of the heat-conducting channel 21 to limit the position of the first insert plate 222 and the second insert plate 243 from shifting.

[0044] This utility model also includes a heat storage structure within the heat conduction channel 21, specifically comprising a guide inner cylinder 261 disposed within the heat conduction channel 21, an air cavity 262 formed within the guide inner cylinder 261, and a buffer cavity 263 formed between the outer wall of the guide inner cylinder 261 and the inner wall of the heat conduction channel 21. The buffer cavity 263 has a relatively small width. (Refer to...) Figure 6 The preferred width is a: 1mm-4mm. The inner wall of the guide cylinder 261 is provided with several second air outlets 264, which connect the buffer chamber 263 and the air chamber 262 through the second air outlets 264.

[0045] During use, the hot airflow directly enters the air cavity 262 formed inside the inner guide cylinder 261. After the air pressure inside the air cavity 262 increases, the airflow enters the buffer cavity 263 from the second air outlet 264. Preferably, at least part of the second air outlet 264 is misaligned with the first air outlet 23, and the diameter of the second air outlet 264 is larger than the diameter of the first air outlet 23, so that the flow rate entering the buffer cavity 263 is greater than the flow rate leaving the buffer cavity 263. The airflow in the buffer cavity 263 will not be directly output from the first air outlet 23, but will form a meandering flow state in the buffer cavity 263, and then be output from the first air outlet 23, so that the hot airflow stays in the heat conduction channel 21 for a longer time and has a better heat storage effect.

[0046] Furthermore, several second air outlets 264 are distributed on opposite sides of the side wall of the inner guide cylinder 261, which facilitates the core pulling of the insert during the manufacturing process and simplifies the mold structure. In addition, there are no holes on the two sides, so the airflow from the second air outlets 264 will flow towards the two sides without empty spaces to form a meandering flow channel.

[0047] Based on the above embodiments, the inner guide cylinder 261 is not directly connected to the heat conduction channel 21. Of course, there are many ways to connect them, which will not be listed here. In this embodiment of the present invention, the end of the heat conduction channel 21 away from the handle 1 is provided with a heat-insulating gripping end cap 41. The heat-insulating gripping end cap 41 is fixedly connected to the inner guide cylinder 261 and is used to limit the position of the heat conduction channel 21. The end of the inner guide cylinder 261 away from the heat-insulating gripping end cap 41 extends out of the heat conduction channel 21 and connects to the handle 1. A plurality of limiting blocks 265 are provided on the side wall of the inner guide cylinder 261. The inner wall of the heat conduction channel 21 is provided with a limiting groove 223 that cooperates with the limiting block 265 to prevent the heat conduction channel 21 and the inner guide cylinder 261 from rotating relative to each other.

[0048] Based on the above, referring to Figure 3 The hot air needs to enter the air cavity 262 formed by the inner guide cylinder 261. For this purpose, the part of the inner guide cylinder 261 extending out of the heat conduction channel 21 is inserted into the handle 1 and abuts against the step 17 formed by the handle 1, so that the airflow will not leak out. Secondly, the heating element 32 extends at least partially out of the handle 1 and into the inner guide cylinder 261, which can better reduce the heat loss of the airflow during the transportation process. Furthermore, the heat generated by the heating element 32 can further heat up the gas inside the air cavity 262.

[0049] Furthermore, referring to Figure 2 and Figure 4 One end of the inner guide cylinder 261 is provided with a connecting part 266. The connecting part 266 passes through the handle 1 and is fixed to the handle 1 by screws. A first locking ring 42 is fixed on the connecting part 266 to cover the first screw mounting position 43. A second locking ring 44 is provided below the first locking ring 42 to cover the second screw mounting position 45. The first screw mounting position 43 is used to connect the inner guide cylinder 261 and the handle 1, while the second screw mounting position 45 is used to fix the handle 1 (described below). In addition, the upper surface of the first locking ring 42 abuts against the lower end of the heat conduction channel 21, the upper end of the second locking ring 44 abuts against the lower end of the first locking ring 42, and the second locking ring 44 abuts against the bottom of the handle 1. Based on this structure, combined with the heat insulation gripping end cap 41, a clamping and fixing state is formed for the heat conduction channel 21.

[0050] In addition, the second locking ring 44 includes a first semicircular ring 441 and a second semicircular ring 442 that are interlocked with each other. The inner sides of the first semicircular ring 441 and the second semicircular ring 442 are respectively provided with a plug-in part 443 that goes into the handle 1 to prevent the second locking ring 44 from rotating.

[0051] The specific installation process is as follows: First, the first locking ring 42 is fitted onto the end of the handle 1, without obstructing the first screw mounting position 43. Then, screws are used to fix the connecting part 266 and the handle 1, so that the handle 1 is connected and fixed to the inner guide cylinder 261. Then, the first locking ring 42 is pushed up to cover the first screw mounting position 43. Then, the first semi-circular ring 441 and the second semi-circular ring 442 are interlocked to fill the position of the first locking ring 42, and the second screw mounting position 45 is covered again.

[0052] One embodiment of the handle 1 of this utility model specifically includes a first inner shell 11, a second inner shell 12, a first outer shell 13, and a second outer shell 14. The first inner shell 11 and the second inner shell 12 are designed in halves and are interlocked. The first outer shell 13 and the second outer shell 14 are also designed in halves, and their upper and lower ends are fixedly connected by screws. It should be noted that a structure for fixing the first inner shell 11 and the second inner shell 12 should be provided in the cavity formed by the first outer shell 13 and the second outer shell 14.

[0053] Additionally, a fixing part 18 is provided on the inner side of the first inner shell 11 and the second inner shell 12, and a fixing hole 267 is provided on the connecting part 266, which can fix the guide inner cylinder 261.

[0054] Furthermore, the fan 31 and the heating element 32 are installed inside the first inner shell 11 and the second inner shell 12, and the air inlet end of the first inner shell 11 or the second inner shell 12 is provided with a noise reduction net 15 corresponding to the air inlet end of the fan 31.

[0055] The first outer shell 13 and the second outer shell 14 together form an end air inlet at the end away from the comb assembly 2, and an air inlet cover 16 is fitted on the end air inlet.

[0056] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
