Description

Technical Field

[0001] The present invention relates to the field of heat dissipation technology, and in particular to a heat dissipation control system. The present invention also relates to a hot and cold comb. Background Art

[0002] Combs are one of the products that people commonly use in daily life. With the improvement of people's living standards, combs have gradually developed from single-functional handmade products such as ordinary wooden combs, plastic combs, and ceramic combs to household appliances with electrical control and intelligent operation.

[0003] Currently, in order to meet users' needs for straightening, curling, and styling their hair when using a comb, combs are often equipped with heat-conducting metal teeth in addition to conventional plastic teeth. These teeth, when used with heating elements such as electric heating wires, can heat the hair (referred to as "hot teeth") to dry out moisture while combing. Since the temperature of the hot teeth is generally around 200°C during use, which is relatively high, prolonged exposure to such high temperatures can easily damage the hair quality or internal structure, leading to denaturation and burning of hair protein, and can easily burn the user's scalp or other parts of the skin. Therefore, combs are often equipped with cold teeth that can be used simultaneously with the hot teeth, creating a hot and cold comb that can heat and cool the hair while combing.

[0004] In the prior art, hot and cold combs are usually divided into a handheld portion and a comb tooth portion, such as Figure 1 As shown, a central row of hot teeth is usually located in the middle of the comb portion, while multiple rows of cold teeth are usually located on the upper and lower sides of the comb portion. The central hot teeth are heated by a heating module in the comb portion, while multiple cooling modules cool each row of cold teeth.

[0005] When combing hair with a hot or cold comb, the user holds the handle tightly to keep it horizontal, and at the same time sweeps the comb teeth up and down, so that the central hot teeth and each row of cold teeth pass through the hair in turn, ensuring that the hair is always in an alternating hot and cold environment during the combing process. However, due to the volume limitation of the hot and cold comb, multiple cooling modules usually need to share the same radiator, which results in excessive heat dissipation load on the radiator, poor heat dissipation effect for all cooling modules, and difficulty in achieving sufficient cooling effect on the hair. If the heat dissipation load of the radiator is to be reduced, the number of radiators must be increased to share the heat dissipation load, but this will inevitably lead to an increase in the overall volume of the hot and cold comb, which is not conducive to miniaturization and lightweight structural design.

[0006] Therefore, how to reduce the heat dissipation load of the radiator while avoiding increasing the volume of the hot and cold combs while ensuring sufficient cooling effect on the hair is a technical problem faced by those skilled in the art. Summary of the Invention

[0007] The present invention aims to provide a heat dissipation control system that can reduce the heat dissipation load of the radiator without increasing the volume of the hot and cold comb, while ensuring sufficient cooling of the hair. Another object of the present invention is to provide a hot and cold comb.

[0008] In order to solve the above technical problems, the present invention provides a heat dissipation control system, comprising a heat dissipation bracket, a heating module arranged in the central area of the surface of the heat dissipation bracket and used to heat the central hot teeth, and several refrigeration modules arranged on the upper and lower sides of the surface of the heat dissipation bracket and used to cool each row of cold teeth respectively. It also includes a heat dissipation control PCB installed in the hot and cold comb housing, a direction sensor arranged on the heat dissipation control PCB and used to detect the current posture of the hot and cold comb, and a control module arranged on the heat dissipation control PCB and connected to the direction sensor signal, used to suspend the operation of each refrigeration module corresponding to each row of cold teeth currently in the lower position, and start the operation of each refrigeration module corresponding to each row of cold teeth currently in the upper position.

[0009] Preferably, it further comprises a temperature sensor provided on the heat dissipation control PCB for detecting the temperature of the central heating tooth, and the temperature sensor is connected to the control module signal so as to control the working state of the heating module.

[0010] Preferably, it further comprises a temperature display module which is arranged on the heat dissipation control PCB and is connected to the temperature sensor signal and is used to display its temperature detection data.

[0011] Preferably, it also includes a motor control module which is arranged on the heat dissipation control PCB and is connected to the heat sink signal in the hot and cold comb and is used to control the working state of the heat dissipation fan in the heat sink.

[0012] Preferably, it further comprises a power module arranged on the heat dissipation control PCB, and a switch module for controlling the output state of the power module.

[0013] Preferably, the direction sensor is a gravity sensor.

[0014] The present invention also provides a hot and cold comb, comprising a central hot tooth, a plurality of rows of cold teeth arranged on the upper and lower sides of the central hot tooth, a radiator, and also comprising a heat dissipation control system as described in any of the above items.

[0015] The heat dissipation control system provided by the present invention mainly includes a heat dissipation bracket, a heat dissipation control PCB, a heating module, a cooling module, a direction sensor, and a control module. Among them, the heat dissipation bracket is installed in the shell of the hot and cold comb, and is mainly used to install the radiator and other components. The heating module is arranged in the central area of the surface of the heat dissipation bracket, and is mainly used to heat the central hot teeth. The cooling module is arranged on the upper and lower sides of the surface of the heat dissipation bracket, and is mainly used to cool the cold teeth. Since there are multiple rows of cold teeth distributed on the upper and lower sides of the central hot teeth, multiple cooling modules are arranged at the same time, and each cooling module corresponds to a row (or several rows) of cold teeth. The heat dissipation control PCB is installed in the shell of the hot and cold comb, and is mainly used for the integrated installation of other electronic components. The direction sensor is arranged on the heat dissipation control PCB, and is mainly used to detect the current posture information of the hot and cold comb, mainly including various posture angles and position parameters. The control module is arranged on the heat dissipation control PCB and maintains a signal connection with the direction sensor, and at the same time maintains a signal connection with its control object, that is, each refrigeration module. It is mainly used to judge the relative position relationship of each row of cooling teeth in the current use posture of the hot and cold comb according to the detection results of the direction sensor, and to suspend the operation of each refrigeration module corresponding to each row of cooling teeth currently in the lower position, and to start the operation of each refrigeration module corresponding to each row of cooling teeth currently in the upper position. In this way, when the user uses the hot and cold comb to comb his hair, the control module controls the working status of each cooling module, so that some cooling modules suspend operation to suspend the cooling of the rows of cold teeth on the lower side, and at the same time keep the other cooling modules working to continue cooling the rows of cold teeth on the upper side, thereby achieving the combing and styling effect of first heating the hair through the central hot teeth and then cooling it through the cold teeth when combing the hair (based on the user's conventional top-down combing scenario). Since the radiator only needs to dissipate heat to the cooling modules in the working state, it can significantly reduce the heat dissipation load of the radiator, ensuring sufficient cooling effect of the hair. Compared with the existing technology, since there is no need to add an additional radiator, the volume of the hot and cold comb can be avoided from increasing, which is conducive to miniaturization and lightweight design.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please refer to Figure 2 、 Figure 3 , Figure 2 This is a schematic diagram of the overall structure of a specific embodiment provided by the present invention. Figure 3 for Figure 2 Schematic diagram from another perspective.

[0026] In a specific embodiment provided by the present invention, the heat dissipation control system mainly includes a heat dissipation bracket c, a heat dissipation control PCB 1 , a heating module 2 , a cooling module 3 , a direction sensor 4 , and a control module 5 .

[0027] Among them, the heat dissipation bracket c is installed in the shell of the hot and cold comb, and is mainly used to install the radiator and other components.

[0028] The heating module 2 is arranged at the center area of the surface of the heat dissipation bracket c, and is mainly used to heat the central heating tooth a.

[0029] Refrigeration modules 3 are located on the upper and lower surfaces of the heat dissipation bracket c, primarily for cooling the cooling teeth b. Because the cooling teeth b are arranged in multiple rows above and below the central heating teeth a, multiple refrigeration modules 3 are provided, each corresponding to one (or more) rows of cooling teeth b.

[0030] The heat dissipation control PCB 1 is installed in the housing of the hot and cold comb and is mainly used to install other electronic components.

[0031] The direction sensor 4 is arranged on the heat dissipation control PCB 1 and is mainly used to detect the current posture information of the hot and cold combs, mainly including various posture angles and position parameters.

[0032] The control module 5 is arranged on the heat dissipation control PCB1 and maintains a signal connection with the direction sensor 4, and at the same time maintains a signal connection with its control object, that is, each refrigeration module 3, etc. It is mainly used to judge the relative position relationship of each row of cold teeth b in the current use posture of the hot and cold comb according to the detection result of the direction sensor 4, and to suspend the operation of each refrigeration module 3 corresponding to each row of cold teeth b currently in the lower position, and to start the operation of each refrigeration module 3 corresponding to each row of cold teeth b currently in the upper position.

[0033] In this way, when the user uses the hot and cold comb to comb his hair, the control module 5 controls the working status of each cooling module 3, so that some cooling modules 3 suspend operation to suspend the cooling of the rows of cold teeth b on the lower side, and at the same time keep the other part of the cooling modules 3 working to continue cooling the rows of cold teeth b on the upper side, thereby achieving the combing and styling effect of first heating the hair through the central hot teeth a and then cooling it through the cold teeth b when combing the hair (based on the user's conventional top-down combing scenario). Since the radiator only needs to dissipate heat to the cooling modules 3 in the working state, it can significantly reduce the heat dissipation load of the radiator, thereby ensuring sufficient cooling effect of the hair. Compared with the existing technology, since there is no need to add an additional radiator, the volume of the hot and cold comb can be avoided from increasing, which is conducive to miniaturization and lightweight design.

[0034] Of course, in order to avoid only some of the refrigeration modules 3 being in working state for a long time, the user can change the holding posture when using the hot and cold comb so that the relative position relationship of each row of cold teeth b is reversed, so that each refrigeration module 3 works in turn.

[0035] like Figure 4 As shown, Figure 4 Schematic diagram of the installation structure of the heating module 2 and each cooling module 3 on the heat dissipation bracket c.

[0036] In a preferred embodiment of the cooling module 3, two cooling modules 3 are provided, one above and one below the heating module 2. Furthermore, two rows of cooling teeth b are provided, one above and one below the central heating tooth a. Each cooling module 3 corresponds to each row of cooling teeth b. Of course, more cooling modules 3 may be provided, such as four.

[0037] Generally, the cooling module 3 can be a thermoelectric cooling chip.

[0038] Considering the limited heat tolerance of hair, this embodiment incorporates a temperature sensor 6. Specifically, this temperature sensor 6 is mounted on the heat dissipation control PCB 1, with its detection end connected to the central heating tooth a. It primarily detects the temperature of the central heating tooth a. Simultaneously, the temperature sensor 6 maintains a signal connection with the control module 5, transmitting the detected temperature data to the control module 5 in real time. The control module 5 then controls the operating state of the heating module 2 based on the difference between the real-time temperature of the central heating tooth a and a preset safety temperature, suspending heating when the real-time detected temperature reaches the preset safety temperature.

[0039] Furthermore, to facilitate user monitoring of the heating status of the central heating tooth a, a temperature display module 7 is provided in this embodiment. Specifically, the temperature display module 7 is mounted on the heat dissipation control PCB 1 and maintains a signal connection with the temperature sensor 6. It is primarily used to display real-time detection data from the temperature sensor 6. Generally, the temperature display module 7 can be mounted on the housing of the hot and cold comb using a digital display or other component for easy user monitoring.

[0040] Furthermore, considering that users may need to adjust the hair temperature appropriately while the hot or cold comb is in operation, a motor control module 8 is added to this embodiment. Specifically, this motor control module 8 is located on the heat dissipation control PCB 1 and maintains a signal connection with the heat sink in the hot or cold comb. It is primarily used to control the operating state of the heat dissipation fan in the heat sink. For example, increasing the speed of the heat dissipation fan, thereby improving the heat dissipation efficiency of the heat sink and achieving a lower perceived temperature on the hair, while decreasing the speed of the heat dissipation fan, thereby reducing the heat dissipation efficiency of the heat sink and achieving a higher perceived temperature on the hair, can control the heat dissipation fan.

[0041] Generally, the motor control module 8 can be mounted on the housing of the hot and cold comb via a button or a slider, etc., for user operation. Of course, the motor control module 8 can also be connected to the control module 5 by signal, so that the built-in program of the control module 5 can automatically control the control instructions of the motor control module 8 to the cooling fan.

[0042] Furthermore, to ensure proper power supply to various circuits on the heat dissipation control PCB 1, as well as to electronic components such as the heating module 2, cooling module 3, and direction sensor 4, this embodiment also incorporates an independent power module 9. Furthermore, to facilitate user control of the hot and cold comb's hot and cold functions, allowing for easy switching between hot and cold and normal settings, this embodiment also incorporates a switch module 10. Specifically, this switch module 10 is mounted on the heat dissipation control PCB 1 and maintains a signal connection with the power module 9. It primarily controls the power module 9's output state, thereby enabling or disabling the power supply circuits to various electronic components.

[0043] In a preferred embodiment of the direction sensor 4, the direction sensor 4 is specifically a gravity sensor. Of course, the direction sensor 4 can also include an angular velocity sensor, a magnetic field sensor, etc.

[0044] This embodiment also provides a hot and cold comb, which mainly includes a central hot tooth a, several rows of cold teeth b arranged on the upper and lower sides of the central hot tooth a, a radiator, and a heat dissipation control system. The specific content of the heat dissipation control system is the same as the above-mentioned related content and will not be repeated here.

[0045] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
