Description

Technical Field

[0001] The utility model specifically relates to a hot air type hair straightener. Background Art

[0002] Hair straighteners, as a household appliance for hairdressing, are widely used in people's daily lives. The traditional hair straightener is also called an electric plywood, or hair straightener in English, commonly called a plywood. It heats the heating element MCH or PTC or heating wire of the hair straightener through electric current, and transmits heat to the aluminum plate or ceramic plate. It is used to clamp the hair so that the physical properties of the hair change and the hair can be straightened. For example, the patent number is CN202220920462.1, and the name is a 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 hair surface 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.

When the first clamp block 11 and the second clamp block 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 then blown out outward along the air guide gap 3.

[0028] As a better implementation of this embodiment, Figures 4 to 7As shown, 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 in the patent with patent number CN202222636804.3 and the name of a hair straightener with uniform dispersion of negative ions, and increase the output of negative ions on the auxiliary clamp 2, which can reduce the split ends of the user's hair and keep the hair smooth and shiny.

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.

[0030] Preferably, 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.

[0031] As a preferred implementation of this embodiment, Figures 2 to 7As shown, 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 capable of generating airflow and conveying the airflow to the air outlet shell 131, the air outlet shell 131 is provided with a heating component 134 capable of heating air, the air outlet shell 131 is provided with an air outlet window 135, the first clamp block 11 is connected to the air outlet shell 131 and the first clamp block 11 covers the air outlet window 135, the first clamp block 11 is provided with a hollow window 110, and the air outlet 12 is surrounded by the edge of the hollow window 110 and the air outlet shell 131. 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 outlet 22 of the air guide sleeve. 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 clamp block 11. Since the first clamp 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 clamp block 11, turns 90 degrees, and then blown out horizontally.

Of course, in this example, the air guide sleeve 132 can also be made of 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.

[0036] In this embodiment, as a more optimal solution, the air guide sleeve 132 adopts an integrated structure made of soft silicone or soft rubber.
