Description

A dual-heating mode electric hair straightener Technical Field

[0001] The utility model specifically relates to an electric heating hair straightener with dual heating modes. 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 hair straighteners, or hair straighteners in English, commonly called hair straighteners. 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 hair straighteners through a heating device. Therefore, this traditional hair straightener can easily cause dry hair due to excessive temperature. The high-temperature hair straighteners directly contact the hair, making the hair surface rough, causing the hair to lose moisture and become dry and yellow. Therefore, the inventors have developed a hair straightener that does not require a high-temperature clamp to hold the hair. Instead, it sends hot air toward the hair, evenly heating the hair locally and thus changing the physical properties of the hair. However, this hair straightener only has the hot air heating function, and the functions available to users are too limited.

[0003] The present invention is based on the above-mentioned shortcomings and produces.

[0024] The utility model is further described below with reference to the accompanying drawings:

[0025] As shown in FIG1 , the present invention has developed a hair straightener comprising a main unit A.

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.

When the main clamp 1 and the secondary clamp 2 are clamped together, the first clamp 11 and the second clamp 21 are abutted against each other and are thereby used to clamp hair. The main clamp 1 is provided with an air outlet 12 located in front of the first clamp 11, the main unit A is provided with a hot air generating device 13 that can generate hot air and blow it out from the air outlet 12, and the secondary clamp 2 is provided with a heating device 22 that can heat the second clamp 21. The above structure can achieve the following functions: 1. The hair straightening clamp product can heat the second clamping block 21 through the heating device 22, thereby clamping the hair with the two clamping blocks to change the physical properties of the hair, thereby achieving the hair straightening function; 2. The hot air generating device 13 generates hot air, which is ultimately blown out from one side of the first clamping block 11 and blown in the direction of the hair, so that the hair can receive a large and uniform heat. The hot air straightens the hair, achieving the straightening effect while preventing the hair from being dehydrated and dry due to the close-range, small-scale heat exposure; 3. The heating device 22 and the hot air generating device 13 operate simultaneously, straightening the hair with hot air, heating the hair with the clamping blocks, and then straightening the hair by clamping the hair with the clamping blocks, ultimately achieving a better straightening effect. In the three straightening modes, the operating power of the heating device 22 and the hot air generating device 13 in different modes can be controlled by setting a control module 14.

[0027] As a preferred embodiment of this embodiment, as shown in Figures 5 and 7, the second clamping block 21 is an integrated structure made of metal or ceramic. Preferably, the second clamping block 21 is an integrated structure made of aluminum, which has good thermal conductivity and certain heat preservation performance.

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 air control component 133 is arranged in the air guide sleeve 132 and can guide the air flow from the air inlet 1321 to the air outlet 1322, the air outlet shell 131 surrounds an air outlet cavity 110, and the air outlet shell 131 is provided with an air inlet 1311 connected to the air outlet 22 of the air guide sleeve, so that the air flow is first generated by the air control component 133, and when the air flow passes through the air outlet cavity 110 It is heated by the heating component 134 and finally blown out from one side of the first clamping block 11, wherein the wind 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.

[0029] In detail, as shown in Figures 3 and 4, the air outlet shell 131 is composed of a bottom cover 1313 and an upper cover 1314.

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.

[0030] In detail, as shown in Figures 3 and 4, the air guide sleeve 132 has a guide section 1323 that gradually shrinks from the air inlet 1321 to the air outlet 1322, so that the air flow generated by the wind control component 133 is compressed when passing through the guide section 1323 to increase the outlet air flow rate.

[0031] As a preferred solution of this embodiment, as shown in Figures 3 and 4, 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 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.

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.

[0033] As a preferred solution of this embodiment, as shown in Figures 2 and 4, a temperature detection device 18 capable of detecting temperature is further provided in the air outlet housing 131, wherein the temperature detection device 18 adopts a thermistor. Of course, the temperature detection device 18 can also adopt other temperature sensors, etc., as long as the temperature detection device 18 can detect the temperature of the hot air flow in the air outlet cavity 100. Preferably, the temperature detection device 18 is arranged at the air outlet of the air outlet cavity 110, and the air temperature therein is detected by the temperature detection device 18, 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.

In addition, the start and stop of the heating component 134 can be controlled separately to control whether the main clamp 1 blows out cold air or hot air. The air temperature of the air outlet cavity 110 is detected by the temperature detection device 18. When the air temperature is detected to be too high, a signal is fed back to the control module 14, and then the control module 14 controls the heating component 134 to stop working.
