Description

Hot air hair straightener Technical Field

[0001] The present invention particularly relates to a hot air hair straightener. Background Art

[0002] Hair straighteners, as a household appliance for hairdressing, are widely used in people's daily lives. Traditional hair straighteners are also called electric plywood, or hair straighteners in English, or plywood in common parlance. They use electric current to heat the heating element MCH or PTC or heating wire of the hair straightener, which is then transferred to an aluminum plate or ceramic plate to generate heat. The heat is used to clamp the hair, causing the physical properties of the hair to change and thus straighten the hair. For example, the patent number is CN202220920462.1, and the name is hair straightener. However, the general principle of these traditional hair straighteners is to heat the plywood through a heating device. Therefore, this traditional hair straightener can easily cause dry hair due to excessive temperature. The high-temperature plywood directly contacts the hair, making the surface of the hair rough, causing the hair to lose moisture, and the hair to become dry and yellow, causing the user's hair to be damaged and inconvenient to use.

[0003] The present invention is just produced based on above-mentioned deficiency.

[0025] The invention will be further described below with reference to the accompanying drawings:

[0026] As shown in FIG1 , the present invention has developed a hair straightener comprising a main unit A. The main unit A is generally provided with two clamping members, a main clamping member 1 and a secondary clamping member 2. The main clamping member 1 and the secondary clamping member 2 are rotatably connected so as to be able to clamp together. The main clamping member 1 and the secondary clamping member 2 are not primary or secondary and can be interchanged. A hair B can be placed between the main clamping member 1 and the secondary clamping member 2, and the hair can be clamped by the main clamping member 1 and the secondary clamping member 2. The hair can then be straightened by the operator pulling the hair.

[0027] As shown in Figures 2 to 4, this embodiment provides a hot air hair straightener, including a main body A, which is provided with a main clamping part 1 and a secondary clamping part 2 that can be clamped together. The main clamping part 1 is provided with a first clamping block 11, and the secondary clamping part 2 is provided with a second clamping block 21 corresponding to the first clamping block 11. When the main clamping part 1 and the secondary clamping part 2 are clamped together, the first clamping block 11 and the second clamping block 21 are abutted against each other and are used to clamp the hair. The main clamping part 1 is provided with an air outlet 12 located in front of the first clamping block 11, and the main body A is provided with a hot air generating device 13 that can generate hot air and blow it out from the air outlet 12. The hot air is generated by the hot air generating device 13, and the hot air is finally blown out from one side of the first clamping block 11 and blown out along the direction of the hair, so that the hair can obtain a large range of uniform heat. The hair is straightened by the hot air, achieving the straightening effect while preventing the hair from being dehydrated and drying out due to close-range and small-scale heating.

[0028] As a preferred implementation of this embodiment, as shown in Figure 1, the inner side surface 100 of the main clamp 1, as shown in Figure 3, the inner side surface 200 of the auxiliary clamp 2, as shown in Figure 4, the first clamp 11 is arranged on the inner side surface of the main clamp 1, and the second clamp 21 is arranged on the inner side surface of the auxiliary clamp 2. When the first clamp 11 and the second clamp 21 are abutted against each other, an air guide gap 3 for air flow to pass through is left between the inner side surface of the main clamp 1 and the inner side surface of the auxiliary clamp 2. The air guide gap 3 is located in front of the air outlet 12, so that the hot air is blown out from the air outlet 12 and blown out outward along the air guide gap 3.

[0029] As a more preferred embodiment of this embodiment, as shown in Figures 4 to 7, the auxiliary clamp 2 is provided with a negative ion generating device 14, and the negative ion generating device 14 is connected to a negative ion output tube 15, and the output end of the negative ion output tube 15 is exposed on the inner side of the auxiliary clamp 2 after passing through the auxiliary clamp 2; or, the main clamp 1 is provided with a negative ion generating device 14, and the negative ion generating device 14 is connected to a negative ion output tube 15, and the output end of the negative ion output tube 15 is exposed on the inner side of the auxiliary clamp 2 after passing through the main clamp 1, so that the hot air blown outward along the air guide gap 3 can transport the negative ions generated by the negative ion output tube 15 outward. Among them, the negative ion generating device 14 can adopt the negative ion generator structure of the patent number CN202222636804.3, which is named a hair straightener with uniform dispersion of negative ions. Increasing the negative ion output on the auxiliary clamp 2 can reduce the split ends of the user's hair and keep the hair smooth and shiny.

[0030] As a better implementation of this embodiment, as shown in Figures 3 and 4, the front side of the main clamp 1 is connected to a first air outlet lip 4, and the front side of the auxiliary clamp 2 is connected to a second air outlet lip 5. When the first clamp 11 and the second clamp 21 are abutted against each other, the first air outlet lip 4 and the second air outlet lip 5 form an air guide port 6, so that the air is blown outward along the air guide gap 3 and finally blown out from the air guide port 6.

[0031] As an example, the first clamping block 11 and the second clamping block 21 are both an integrated structure made of metal or ceramic. Of course, the first clamping block 11 and the second clamping block 21 can also be made of materials such as quartz.

[0032] As a preferred implementation of this embodiment, as shown in Figures 2 to 7, the hot air generating device 13 includes an air outlet shell 131 and an air guide sleeve 132 whose inner cavities are interconnected. The air guide sleeve 132 is provided with an air-making component 133 that can generate airflow and transport the airflow to the air outlet shell 131. The air outlet shell 131 is provided with a heating component 134 that can heat the air. The air outlet shell 131 is provided with an air outlet window 135. The first clamp 11 is connected to the air outlet shell 131 and the first clamp 11 covers the air outlet window 135. The first clamp 11 is provided with a hollow window 110, and the edge of the hollow window 110 and the air outlet shell 131 form the air outlet 12. In detail, the two ends of the air guide sleeve 132 are respectively an air inlet 1321 and an air outlet 1322. The wind control component 133 is arranged in the air guide sleeve 132 and can guide the airflow from the air inlet 1321 to the air outlet 1322. The air outlet shell 131 forms an air outlet cavity 110. The air outlet shell 131 is provided with an air inlet 1311 connected to the air guide sleeve outlet 22. In this way, airflow is first generated by the wind control component 133, and the airflow is heated by the heating component 134 when passing through the air outlet cavity 110, and finally blown out from one side of the first clamping block 11. Since the first clamping block 11 is covered on the air outlet window 135, the hot air is blown out vertically from the air outlet window 135 and then blocked by the first clamping block 11, turns 90°, and blown out horizontally. The wind-making component 133 can refer to the fan component in the patent scheme with patent number CN202221694308.7 and the name of a multifunctional curling iron, and the heating component 134 can adopt a general resistive heating tube or resistive heating sheet, etc., or refer to the heating element in the patent scheme with patent number CN202221694308.7 and the name of a multifunctional curling iron.

[0033] In detail, as shown in Figures 5 and 6, the air outlet shell 131 is composed of a bottom cover 1313 and an upper cover 1314. The inner wall of the bottom cover 1313 is provided with a first heat-resistant partition 136 corresponding to the heating component 134, and the inner wall of the upper cover 1314 is provided with a second heat-resistant partition 137 corresponding to the heating component 134. In this embodiment, the bottom cover 1313 and the upper cover 1314 are connected and fixed by providing threaded holes on both and then threading screws. Of course, the bottom cover 1313 and the upper cover 1314 can also be connected and fixed by snap fasteners or glue bonding. In addition, the first heat-resistant partition 136 and the second heat-resistant partition 137 can be made of metal or ceramic to prevent the heat generated by the heating component 134 from being transferred to the bottom cover 1313 and the upper cover 1314, causing damage to the product.

[0034] As a preferred solution of this embodiment, as shown in Figures 2 and 6, a temperature detection device 16 capable of detecting temperature is further provided in the air outlet housing 131, wherein the temperature detection device 16 adopts a thermistor. Of course, the temperature detection device 16 can also adopt other temperature sensors, etc., as long as the temperature detection device 16 can detect the temperature of the hot air flow in the air outlet cavity 100. Preferably, the temperature detection device 16 is arranged at the air outlet of the air outlet cavity 110, and the air temperature therein is detected by the temperature detection device 16, and the feedback is given to the control module in the product to control the operation of the heating component 134 to avoid the hot air temperature being too high and causing damage to the hair.

[0035] Specifically, as shown in Figures 5 and 6, the air guide sleeve 132 includes a guide section 1323 that gradually tapers from the air inlet 1321 to the air outlet 1322. This compresses the airflow generated by the air control assembly 133 as it passes through the guide section 1323, increasing the outlet airflow velocity. Preferably, the guide section 1323 gradually changes from a circular shape to a flat shape from the air inlet end to the air outlet end, thereby forming a flattened airflow after the hot air is blown out.

[0036] As a preferred solution of this embodiment, as shown in Figures 5 and 6, the front end of the guide section 1323 is open to form the air outlet 1322. The front end of the guide section 1323 is sleeved on the end of the air outlet housing 131, and the front end of the guide section 1323 is provided with a plurality of snap-fit ​​holes 1323 around the air outlet 1322. The air outlet housing 131 is provided with snap-fit ​​protrusions 1312 around the air inlet 1311 that can be inserted into the snap-fit ​​holes 1323. The snap-fit ​​protrusions 1312 snap into the snap-fit ​​holes 1323, thereby achieving the connection and fixation between the air guide sleeve 132 and the air outlet housing 131. Of course, in this example, the air guide sleeve 132 can also be made of a soft material, so that the front end of the air guide sleeve 132 can be directly sleeved on the end of the air outlet housing 131.

[0037] In this embodiment, as a more optimal solution, the air guide sleeve 132 adopts an integrated structure made of silicone. The entire air guide sleeve 132 is a soft sleeve made of silicone material. This is done to fit over the end of the air outlet housing 131 and to better fit against the inner wall of the hair straightener housing, thereby improving the stability of the installation. In addition, the most important function is that the soft air guide sleeve 132 is sheathed around the air control component 133, which can block the transmission of vibration and reduce the efficiency of noise transmission, thereby greatly reducing the impact of vibration and noise and improving the comfort of product use.

[0038] As a variation of this embodiment, a heating device 22 capable of heating the second clamping block 21 can be provided on the secondary clamping member 2. As shown in Figures 4 and 7, the second clamping block 21 preferably utilizes an integrated aluminum structure, which has good thermal conductivity and certain heat preservation properties. The second clamping block 21 is provided with a receiving cavity 210, and the heating device 22 includes a heating element 221 disposed in the receiving cavity 210. The heating element 221 is a PTC heater, an MCH ceramic heater, or a heating film.

[0039] As a preferred implementation of this embodiment, as shown in Figures 4 and 7, the two side walls of the second clamping block 21 are provided with a receiving groove 210 for the metal heating wire 221 to pass through. The metal heating wire 221 is inserted into the receiving groove 210 and is arranged around the second clamping block 21. The metal heating wire 221 is connected to the circuit board or the power supply of the product via a wire. The specific connection method is not shown in the figure and belongs to the conventional technology in this field and is not described in detail. The heat generated by the above-mentioned metal heating wire 221 is transferred to the second clamping block 21, thereby heating the second clamping block 21.
