Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hair styling tools, and in particular to a hair straightener. Background Technology
[0002] The temperature sensor of existing hair straighteners is located at the heating element, which means that the temperature sensor is far away from the metal teeth that are in direct contact with the hair. As a result, the temperature of the metal teeth decreases during the heat exchange process with the hair, but the temperature sensor cannot detect the temperature change quickly. It is often only detected when the temperature of the metal teeth drops to 20-50°C lower than that of the heating element. This results in the actual product being styled at a temperature that is much lower than the set temperature, causing problems such as poor styling effect of the hair straightener. Utility Model Content
[0003] The main purpose of this invention is to propose a hair straightener that aims to improve the accuracy of temperature sensor detection and enhance the styling effect of the hair straightener.
[0004] To achieve the above objectives, the hair straightener proposed in this utility model includes:
[0005] The housing includes a grip section and a comb section, wherein an installation cavity is formed in the grip section and a heating cavity is formed in the comb section;

[0009] A temperature sensor is electrically connected to the electronic control board and is located inside the detection cavity, on the side of the comb plate away from the heating element.
[0010] In one embodiment, the temperature sensor is embedded in the detection cavity.
[0011] In one embodiment, one of the detection chambers is provided with one or more of the temperature sensors.
[0012] In one embodiment, the end face of the comb teeth is higher than the end face of the detection teeth.
[0013] In one embodiment, the heating tooth is made of a thermally conductive material, and the first protective tooth is made of a plastic material.
[0014] In one embodiment, the comb plate includes a first comb plate and a second comb plate, the comb teeth include heating teeth and a first protective tooth, the heating teeth and the detection teeth are connected to the first comb plate, the first protective tooth is connected to the second comb plate, the second comb plate is connected to the side of the first comb plate away from the heating cavity, and the first protective tooth is sleeved on the end of the heating teeth away from the first comb plate.
[0015] In one embodiment, the comb plate further includes a third comb plate, which is provided with second protective teeth and is arranged around the periphery of the first comb plate.
[0016] In one embodiment, the end face of the second protective tooth is higher than the end face of the first protective tooth.
[0017] In one embodiment, the third comb plate is provided with a first mounting portion, and the housing is provided with a second mounting portion. The third comb plate is mounted on the housing through the first mounting portion and the second mounting portion.
[0018] In one embodiment, the first mounting part is a hook, the second mounting part is a snap-fit hole, and the third comb plate is connected to the housing by the engagement of the hook and the snap-fit hole.

[0020] In one embodiment, the hair straightener further includes a heat insulation plate connected to the housing and located on the side of the heat-conducting plate opposite to the comb plate.
[0021] In this invention, a heating element is installed inside a heating chamber and electrically connected to an electronic control board. The heat emitted by the heating element is transferred to the comb plate, and then to the comb teeth and detection teeth. Both the comb teeth and detection teeth can heat the user's hair.

[0036] Reference Figures 1 to 3 This utility model proposes a hair straightener, comprising:
[0037] The housing 10 includes a grip section 11 and a comb section 12, wherein an installation cavity is formed in the grip section 11 and a heating cavity is formed in the comb section 12;
[0038] An electronic control board is connected to the housing 10 and located within the mounting cavity;
[0039] A heating element is installed in the housing 10 and located inside the heating cavity; the heating element is electrically connected to the electronic control board.
[0040] A comb plate 20, on which a plurality of combing teeth and at least one detection tooth 212 are spaced apart, the detection tooth 22 being located on the side of the comb plate 20 opposite to the heating element; the comb plate 20 is connected to the housing 10 and located at the opening of the heating cavity; the detection tooth 212 has a detection cavity 212a that penetrates the comb plate 20; and
[0041] A temperature sensor is electrically connected to the electronic control board and is located inside the detection cavity 212a, on the side of the comb plate 20 away from the heating element.
[0042] In this invention, a heating element is installed inside a heating chamber and electrically connected to an electronic control board. The heat emitted by the heating element is transferred to the comb plate 20, and then to the comb teeth and detection teeth 212. Both the comb teeth and the detection teeth 212 can heat the user's hair. However, a temperature sensor is also installed inside the detection teeth 212, allowing the detection teeth 212 to detect their own temperature, which is equivalent to detecting the temperature of the comb teeth. Compared to the prior art where the temperature sensor is located at the heating element, this invention directly installs the temperature sensor in the detection chamber 212a of the detection teeth 212, and the temperature sensor is located on the side of the comb plate 20 away from the heating element. This allows the temperature sensor to quickly and accurately detect any change in the temperature of the detection teeth 212, thereby improving the accuracy and timeliness of the temperature sensor detection. This allows the hair straightener to heat the user's hair at a more suitable temperature, thus improving the styling effect of the hair straightener.
[0043] Specifically, the temperature sensor is embedded in the detection cavity, which allows the temperature sensor to be stably fixed in the detection cavity, thereby improving the stability and reliability of the temperature sensor. At the same time, embedding the temperature sensor in the detection cavity also increases the contact area between the temperature sensor and the cavity wall, thereby improving the accuracy of temperature sensor detection.
[0044] In one embodiment, one or more temperature sensors are provided for each of the detection chambers. Using multiple temperature sensors increases the accuracy of detection and reduces the possibility of temperature detection failure due to the malfunction of individual temperature sensors, thereby improving the stability and reliability of the hair straightener. Of course, in other embodiments, only one temperature sensor may be provided within each detection chamber. Alternatively, multiple detection chambers may be provided within a single detection tooth, with at least one temperature sensor corresponding to each detection chamber.
[0045] Specifically, the end face of the comb teeth is higher than the end face of the detection teeth 212, so that the detection teeth 212 are recessed inside the comb teeth, thereby avoiding excessive influence of the external environment on the detection teeth 212, thus improving the stability and reliability of the detection by the detection teeth 212.
[0046] Reference Figures 4 to 6 In one embodiment, the comb plate 20 includes a first comb plate 21 and a second comb plate 22. The comb teeth include heating teeth 211 and a first protective tooth 221. The heating teeth 211 and the detection teeth 212 are connected to the first comb plate 21. The first protective tooth 221 is connected to the second comb plate 22. The second comb plate 22 is connected to the side of the first comb plate 21 away from the heating cavity. The first protective tooth 221 is sleeved on the end of the heating tooth 211 away from the first comb plate 21. The comb teeth are primarily used to heat the user's hair, which is then straightened by the user operating the hair straightener. To prevent burns from the ends of the comb teeth when they come into contact with the user's skin, the comb teeth are configured with heating teeth 211 and first protective teeth 221. The first protective teeth 221 protect the user by being made of heat-conducting material to heat the user's hair, and heat-insulating material to reduce the temperature transferred from the heating teeth 211 to the first protective teeth 221, thereby reducing the possibility of burns from the first protective teeth 221.
[0047] Furthermore, the end face of the first protective tooth 221 is higher than the end face of the detection tooth 212. It is understood that the end of the detection tooth 212 is not provided with the first protective tooth 221; therefore, to avoid the detection tooth 212 burning the user, the height of the detection tooth 212 is reduced, thereby preventing the detection tooth 212 from burning the user.
[0048] Furthermore, the heating teeth 211 are made of a thermally conductive material, while the first protective teeth 221 and / or the second protective teeth 231 are made of plastic. The thermally conductive material can be copper, iron, or other alloys, or even other composite thermally conductive materials, thereby reducing heat loss during heat transfer. The use of plastic for insulation in the first and second protective teeth 221 and 231 reduces the possibility of burns to the user. Additionally, the lower cost of plastic reduces the manufacturing cost of the hair straightener.
[0049] Furthermore, the comb plate 20 also includes a third comb plate 23, on which a second protective tooth 231 is provided, and the third comb plate 23 is arranged around the periphery of the first comb plate 21. By providing the third comb plate 23, the user is prevented from being burned by the outer heating teeth 211, thereby further playing a role in heat insulation and preventing burns, and further improving the user experience.
[0050] Specifically, the end face of the second protective tooth 231 is higher than the end face of the first protective tooth 221. By making the end face of the second protective tooth 231 higher than the end face of the first protective tooth 221, it provides further protection against burns for the user, thereby further improving the safety and reliability of the hair straightener.
[0051] Reference Figure 2 and Figure 7 In one embodiment, the third comb plate 23 is provided with a first mounting portion, and the housing 10 is provided with a second mounting portion. The third comb plate 23 is mounted on the housing 10 through the first mounting portion and the second mounting portion. It is understood that hair straighteners are inevitably subject to impacts during daily use. Since the third comb plate 23 is located on the outer periphery of the first comb plate 21 and the second comb plate 22, by making the third comb plate 23 a detachable structure, it is easy to replace the third comb plate 23, thereby improving the service life of the hair straightener.
[0052] Specifically, the first mounting part is a hook 232, the second mounting part is a snap-fit hole, and the third comb plate 23 is connected to the housing 10 by the engagement of the hook 232 and the snap-fit hole. The connection method of the hook 232 and the snap-fit hole is simple and reliable, thereby improving the user's disassembly and assembly efficiency, and the manufacturing cost is low.
[0053] Furthermore, the hair straightener also includes a heat-conducting plate 31, within which a heat-conducting cavity is formed. The heat-conducting plate 31 is connected to the housing 10 and located within the heating cavity. The heating element is fitted and connected within the heat-conducting cavity, and the heat-conducting plate 31 abuts against the side of the comb plate 20 opposite to the comb teeth. Understandably, the size of the heating element limits its ability to simultaneously contact the area of the comb plate 20 corresponding to the comb teeth. Therefore, by setting the heat-conducting plate 31, the heat emitted by the heating element is quickly and evenly distributed throughout the entire heat-conducting plate 31. The heat-conducting plate 31 then transfers the heat to the entire comb plate 20, and the comb plate 20 transfers all the heat to all the comb teeth and all the detection teeth 212. This ensures that there is no significant difference in the amount of heat received by all the comb teeth and detection teeth 212, thereby reducing the problem of excessive temperature differences among the comb teeth, improving the stability and reliability of the hair straightener, and ultimately enhancing its styling effect.
[0054] In one embodiment, the hair straightener further includes a heat insulation plate 32 connected to the housing 10 and located on the side of the heat-conducting plate 31 facing away from the comb tooth plate 20. Understandably, the heat emitted by the heating element is primarily intended to be transferred to the comb teeth and detection teeth 212. Therefore, by providing the heat insulation plate 32, the heat emitted by the heating element is reduced from being transferred to the back of the housing 10, thereby reducing the heat in the housing 10 of the comb section 12, thus reducing the possibility of the housing 10 burning the user, and improving the user experience.
[0055] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
