Description

Technical Field

[0001] This utility model relates to the field of hair styling equipment technology, and in particular to a hair straightener with heat circulation. Background Technology

[0002] With the development of technology and consumers' pursuit of convenience and aesthetics, cordless hair straighteners have gradually become popular products on the market. These products typically integrate the heating function of the plates with the drying function of a hair dryer, providing users with a convenient solution that can both straighten hair and dry it quickly. However, current cordless hair straighteners on the market still have some significant shortcomings in design and function.

[0003] Most existing cordless hair straighteners use a design with heated plates, where heating elements heat the plates to straighten hair. Simultaneously, a built-in motor drives an impeller to generate cool or warm air to aid in drying. While this design meets user needs to some extent, it has revealed problems such as high energy consumption and short battery life in actual use.

[0004] Specifically, the heating element in the hair straightener plate consumes a significant amount of power, and the motor also consumes a considerable amount of power during continuous airflow. Since cordless hair straighteners rely on battery power, this high energy consumption directly leads to a significant reduction in battery life, requiring users to charge frequently, which severely impacts convenience and user experience. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hair straightener with heat circulation.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model provides a hair straightener with heat circulation, including: an upper clamping assembly and a lower clamping assembly hinged to the upper clamping assembly, wherein the upper clamping assembly is connected to the lower clamping assembly, the upper clamping assembly is provided with an upper clamping plate, the lower clamping assembly is provided with a lower clamping plate corresponding to the upper clamping plate, the upper clamping plate is provided with a first air hole, and the lower clamping plate is provided with a second air hole corresponding to the first air hole. The upper clamping assembly or the lower clamping assembly is provided with a heating frame and a driving member inside, the heating frame generates heat to form hot air, and the driving member blows the hot air out along the first air hole or the second air hole for drying hair, wherein a portion of the hot air enters the lower clamping assembly or the upper clamping assembly along the second air hole or the first air hole until it flows back to the heating frame.

[0008] In one specific embodiment, the upper clamping component or the lower clamping component is further provided with comb teeth on both sides of the first air hole or the second air hole.

[0009] In one specific embodiment, the upper clamping assembly is further provided with an upper support in the area corresponding to the upper clamping plate, and the upper clamping plate is connected to the upper support.

[0010] In one specific embodiment, an upper sealing element is also provided between the upper clamping plate and the upper bracket.

[0011] In one specific embodiment, the lower clamping assembly is further provided with a lower support in the area corresponding to the lower clamping plate, and the lower clamping plate is connected to the lower support.

[0012] In one specific embodiment, a lower sealing element is further provided between the lower clamping plate and the lower support.

[0013] In one specific embodiment, the upper clamping assembly has an air guide tube on the side facing the lower clamping assembly, and the lower clamping assembly has an air guide hole corresponding to the air guide tube.

[0014] In one specific embodiment, a sealing ring is provided at the edge of the air guide hole.

[0015] In one specific embodiment, the upper clamping assembly is further provided with an adjustment switch.

[0016] In one specific embodiment, the upper clamping assembly is further provided with an indicator light.

[0017] The advantages of this heat-circulating hair straightener compared to existing technologies are as follows: By designing an upper clamping assembly and a lower clamping assembly that are internally connected, and each assembly has an upper clamping plate and a lower clamping plate respectively. The upper clamping plate has a first air hole, and the lower clamping plate has a corresponding second air hole. This structural design provides the basis for heat circulation. The heating element generates heat to form hot air, which is then blown out along the air holes for drying hair. Importantly, some of the hot air is not directly lost to the air, but flows back to the heating element along the reverse air holes. This heat circulation design... This design allows the heating element to preheat or maintain the temperature using recirculated hot air, reducing the need for new heat generation and lowering the power consumption of the heating element. Since the heating element is one of the most energy-consuming components in a hair straightener, reducing its power consumption through the thermal circulation design directly leads to a reduction in overall energy consumption. For cordless hair straighteners, reduced energy consumption means that the battery can last longer under the same usage conditions, thus greatly extending battery life. This not only improves the user experience but also reduces the inconvenience of frequent charging, making cordless hair straighteners more convenient and practical.

[0031] See Figures 1 to 4The present invention discloses a hair straightener with a heat circulation system, as shown in the specific embodiment, comprising: an upper clamping assembly 10 and a lower clamping assembly 20 hinged to the upper clamping assembly 10, wherein the upper clamping assembly 10 is connected to the lower clamping assembly 20, the upper clamping assembly 10 is provided with an upper clamping plate 11, and the lower clamping assembly 20 is provided with a lower clamping plate 21 corresponding to the upper clamping plate 11, wherein the upper clamping plate 11 is provided with a first air hole 111, and the lower clamping plate 21 is provided with a corresponding air hole 111. The second air hole 211 of 11, the upper clamping assembly 10 or the lower clamping assembly 20 is provided with a heating frame 30 and a driving member 40. The heating frame 30 generates heat to form hot air. The driving member 40 blows the hot air out along the first air hole 111 or the second air hole 211 for drying hair. A portion of the hot air enters the lower clamping assembly 20 or the upper clamping assembly 10 along the second air hole 211 or the first air hole 111 until it flows back to the heating frame 30.

[0032] Specifically, the hair straightener consists of an upper clamping assembly 10 and a lower clamping assembly 20, which are connected by a hinge, allowing the straightener to be easily opened and closed. The upper clamping assembly 10 has an upper clamping plate 11, and the lower clamping assembly 20 has a lower clamping plate 21 corresponding to the upper clamping plate 11, used to clamp the hair and straighten it. The upper clamping plate 11 has a first air hole 111, and the lower clamping plate 21 has a second air hole 211 corresponding to the first air hole 111. These air holes form part of the hot air circulation path. A heating frame 30 is provided inside the upper clamping assembly 10 or the lower clamping assembly 20. When the heating frame 30 is working, it generates heat to form hot air, providing the necessary heat energy for the straightener. At the same time, a driving component 40 (such as a small fan or blower) is provided to blow the hot air generated by the heating frame 30 along the first air hole 111 or the second air hole 211, directly acting on the hair to achieve the effect of drying and straightening the hair. During the operation of the hair straightener, some hot air enters the lower clamping assembly 20 or the upper clamping assembly 10 through the second air hole 211 or the first air hole 111, and then flows back to the heating frame 30. This design allows the hot air to circulate inside the hair straightener. The driving component 40 blows the returning hot air back onto the heating frame 30, using the residual heat of the hot air to preheat the heating frame 30 or maintain its operating temperature.

[0033] In other words, the design of the thermal circulation air path allows the recirculated hot air to be reused, reducing the need for the heating element 30 to generate new heat. This significantly reduces the power consumption of the heating element 30, thereby reducing the overall energy consumption of the hair straightener. Furthermore, for a cordless hair straightener, reduced energy consumption means the battery can last longer under the same usage conditions. The thermal circulation air path design effectively extends battery life, improves the user experience, and reduces the inconvenience of frequent charging, making cordless hair straighteners more convenient and practical.

[0034] More specifically, the heating element 30 and the driving element 40 are disposed on the lower clamping assembly 20, the first air hole 111 is an air outlet, and the second air hole 211 is an air inlet.

[0035] In one embodiment, the upper clamping component 10 or the lower clamping component 20 is further provided with comb teeth 22 on both sides of the first air hole 111 or the second air hole 211.

[0036] Specifically, on the upper clamping assembly 10 or the lower clamping assembly 20, comb teeth 22 are provided on both sides of the first air hole 111 or the second air hole 211. These comb teeth 22 are arranged parallel to the air holes, forming a special structure. The design of the comb teeth 22 takes into account the characteristics of hair and the way the hair straightener is used. They are carefully arranged on both sides of the air holes to ensure effective contact with the hair during use. The first air hole 111 and the second air hole 211 are designed to be aligned, so that when the hair straightener clamps the hair, the two air holes can form a straight airflow channel. When clamping the hair, the comb teeth 22 on both sides will naturally open the hair, so that the hair will not directly cover or block the air holes. Due to the opening effect of the comb teeth 22, when the drive unit 40 is working, the generated hot air can be smoothly blown out from one air hole (such as the first air hole 111) and act on the hair. At the same time, another part of the hot air can be drawn in through another air hole (such as the second air hole 211), forming an airflow circulation. This design ensures that the air vents can fully function for both air intake and exhaust.

[0037] In other words, the comb teeth 22 effectively prevent hair from clogging the air holes during the use of the hair straightener, ensuring smooth airflow. This not only improves the efficiency of the hair straightener but also avoids product malfunctions or damage caused by clogged air holes. Furthermore, after the comb teeth 22 open up the hair, the airflow channels between the air holes become more unobstructed, making the hot air intake and exhaust more efficient. This helps to speed up the drying and straightening process, improving the overall effect of the hair straightener.

[0038] In one embodiment, the upper clamping assembly 10 is further provided with an upper support 12 in the area corresponding to the upper clamping plate 11, and the upper clamping plate 11 is connected to the upper support 12.

[0039] Specifically, in the upper clamping assembly 10, an upper bracket 12 is designed and installed in the area corresponding to the upper clamping plate 11. The upper bracket 12, as a supporting structure for the upper clamping plate 11, has been carefully designed and selected in terms of shape, size, and material to ensure a stable connection and good fit with the upper clamping plate 11. The upper clamping plate 11 is securely connected to the upper bracket 12 using appropriate connection methods (such as screw fixing, snap-fit ​​connection, welding, etc.). The selection of the connection method considers ease of use, connection stability, and ease of disassembly, ensuring that the upper clamping plate 11 will not loosen or fall off during use.

[0040] In other words, the upper bracket 12, as the supporting structure for the upper clamping plate 11, significantly improves the stability and firmness of the upper clamping plate 11. During use, even under significant external force, the upper clamping plate 11 remains stable and is not easily deformed or damaged. Furthermore, the secure connection between the upper bracket 12 and the upper clamping plate 11 ensures stability when clamping hair, making users feel more confident and comfortable when using the hair straightener.

[0041] In one embodiment, an upper sealing element is also provided between the upper clamping plate 11 and the upper bracket 12.

[0042] Specifically, an upper seal is specially provided at the connection between the upper clamp 11 and the upper bracket 12. The upper seal is made of a material that is elastic, heat-resistant, and has good sealing performance, such as silicone, rubber, or a specific sealing alloy material. The shape and size of the seal are precisely designed to fit tightly against the connection surfaces of the upper clamp 11 and the upper bracket 12, ensuring no gaps or leaks. The main function of the upper seal is to ensure the air passage between the upper clamp 11 and the upper bracket 12 is airtight. When the straightener is working, the airflow or hot air generated by the drive unit 40 flows along the set air passage. The presence of the upper seal prevents airflow or hot air from leaking from the connection, ensuring the integrity and efficiency of the air passage.

[0043] In other words, the upper seal significantly improves the airtightness of the air passage between the upper clamp 11 and the upper bracket 12. This ensures that airflow or hot air can flow along the set path without being lost due to leakage, thus improving the efficiency and effectiveness of the hair straightener. Furthermore, the improved airtightness reduces noise and vibration during operation. Users can enjoy the straightening process more quietly, while avoiding potential burns or discomfort caused by airflow leakage.

[0044] In one embodiment, the lower clamping assembly 20 is further provided with a lower support 23 in the area corresponding to the lower clamping plate 21, and the lower clamping plate 21 is connected to the lower support 23.

[0045] Specifically, in the lower clamping assembly 20, a lower bracket 23 is designed and installed in the area corresponding to the lower clamping plate 21. The lower bracket 23, as a support structure for the lower clamping plate 21, has been carefully designed and selected in terms of shape, size, and material to ensure a stable connection and good fit with the lower clamping plate 21. The lower clamping plate 21 is securely connected to the lower bracket 23 using appropriate connection methods (such as screw fixing, snap-fit ​​connection, welding, etc.). The selection of the connection method considers ease of use, connection stability, and ease of disassembly, ensuring that the lower clamping plate 21 will not loosen or fall off during use.

[0046] In other words, the lower support 23, as the supporting structure for the lower clamp 21, significantly improves the stability and firmness of the lower clamp 21. During use, even under significant external force, the lower clamp 21 remains stable and is not easily deformed or damaged. Furthermore, the secure connection between the lower support 23 and the lower clamp 21 ensures stability when clamping hair, making users feel more confident and comfortable when using the hair straightener.

[0047] In one embodiment, a lower sealing element is also provided between the lower clamping plate 21 and the lower support 23.

[0048] Specifically, a lower seal is specially provided at the connection between the lower clamp 21 and the lower support 23. The lower seal is made of a material that is elastic, heat-resistant, and has good sealing performance, such as silicone, rubber, or a specific sealing alloy. The shape and size of the seal are precisely designed to fit tightly against the connection surfaces of the lower clamp 21 and the lower support 23, ensuring no gaps or leaks. The main function of the lower seal is to ensure the air passage between the lower clamp 21 and the lower support 23 is airtight. When the straightener is working, the airflow or hot air generated by the drive unit 40 flows along the set air passage. The presence of the lower seal prevents airflow or hot air from leaking from the connection, ensuring the integrity and efficiency of the air passage.

[0049] In other words, the lower seal significantly improves the airtightness of the air passage between the lower clamp 21 and the lower support 23. This ensures that airflow or hot air can flow along the set path without being lost due to leakage, thus improving the efficiency and effectiveness of the hair straightener. Furthermore, the improved airtightness reduces noise and vibration during operation. Users can enjoy the straightening process more quietly, while avoiding potential burns or discomfort caused by airflow leakage.

[0050] In one embodiment, the upper clamping assembly 10 is provided with an air guide tube 13 on the side facing the lower clamping assembly 20, and the lower clamping assembly 20 is provided with an air guide hole 24 corresponding to the air guide tube 13.

[0051] Specifically, one or more air guide tubes 13 are installed on the side of the upper clamping assembly 10 facing the lower clamping assembly 20. These air guide tubes 13 are typically hollow and are used to guide the flow of hot air. The lower clamping assembly 20 is provided with air guide holes 24 corresponding to the air guide tubes 13. The position, size, and shape of these air guide holes 24 are matched with the air guide tubes 13 to ensure that the hot air can pass through smoothly. The heating frame 30 generates heat to form hot air. The driving component 40 blows the hot air out along the second air hole 211 for drying hair. A portion of the hot air enters the upper clamping assembly 10 along the first air hole 111, and then flows down to the lower clamping assembly 20 through the air guide tubes 13 and the air guide holes 24 until it flows back to the heating frame 30, forming a heat cycle.

[0052] In one embodiment, a sealing ring is provided at the edge of the air guide hole 24.

[0053] Specifically, a sealing ring is designed and installed at the edge of the air vent 24 of the lower clamping assembly 20. The sealing ring fits tightly against the edge of the air vent 24, forming a closed ring to ensure that hot air does not leak when passing through the air vent 24. The sealing ring is typically made of a high-temperature resistant, corrosion-resistant material with a certain degree of elasticity, such as silicone rubber or fluororubber. These materials maintain stable performance at high temperatures while providing good sealing. The sealing ring can be installed on the lower clamping assembly 20 by pressing, bonding, or snapping. During installation, it is necessary to ensure that the sealing ring fits tightly against the edge of the air vent 24 without gaps or looseness.

[0054] In one embodiment, the upper clamping assembly 10 is further provided with an adjustment switch 14.

[0055] Specifically, the adjustment switch 14 can be a knob, button, or slider, depending on the design requirements of the hair straightener and the user's habits. The adjustment switch 14 is used to control certain key parameters of the hair straightener, such as temperature and airflow speed (if the straightener has a blow-drying function). To facilitate user operation, the adjustment switch 14 is usually clearly marked with labels or scales indicating the current setting. Some high-end hair straighteners may also be equipped with a display screen that shows the current temperature, airflow speed, and other parameters in real time, helping users adjust more accurately.

[0056] In other words, the design of the adjustment switch 14 allows users to flexibly adjust the parameters of the hair straightener according to their hair type and needs, such as selecting a suitable hair temperature to avoid damage to the hair from excessively high or low temperatures. This personalized adjustment method enhances the user experience and meets the needs of different users. Furthermore, by precisely adjusting the straightener's parameters, users can achieve more ideal straightening results for different hair types and styling needs. For example, for fine, soft hair, a lower temperature and airflow can be selected to avoid excessive dryness; for coarse, stiff hair, a higher temperature and airflow can be selected to improve straightening efficiency.

[0057] In one embodiment, the upper clamping assembly 10 is further provided with an indicator light.

[0058] Specifically, indicator lights can be single or multiple, designed according to the functional requirements of the hair straightener. For example, indicator lights for different functions can display heating status, working mode, battery level, etc. Different colors can be used to distinguish different states, such as red indicating heating, green indicating the set temperature has been reached, and blue indicating a specific working mode. Indicator lights can also convey more information through flashing patterns; for example, rapid flashing may indicate a product malfunction, while slow flashing may indicate low battery.

[0059] In one embodiment, the drive unit 40 consists of a motor and an impeller. The motor drives the impeller to rotate, thereby causing the hot air of the hair straightener to circulate.

[0060] The other structures of the upper clamping component 10 and the lower clamping component 20 adopt existing publicly available technologies and will not be described in detail here.

[0061] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
