Problems solved by technology

[0002] At present, in the known hair curlers, the PTC heating element is provided in the hair curler, and the PTC heating element is arranged in the inside of the aluminum tube of the hair curler in a suspended manner. The heat of the PTC heating element is transferred to the aluminum tube through the pressing sheet, and the pressing sheet and the aluminum tube are connected by an arc surface. The arc itself is poorly matched, and the heat transfer efficiency is low. The surface temperature of the aluminum tube is about 220, the temperature deviation between the PTC heating element and the aluminum tube is very large, and the large deviation is easy to cause damage to the hair quality

Embodiment Construction

[0011] Such as Figure 1-Figure 2 As shown, it is a hair curler of the present invention, which includes an aluminum tube 2, a PTC heating element 3 is arranged inside the aluminum tube 2, and a hairpin 4 is elastically and movably connected to the aluminum tube 3. The hairpin 4 is connected to the aluminum tube 2 through the torsion spring 5, the torsion spring pressure plate 6, the screw 7 and the cone head 8. There is a button 41 on the hairpin 4. When you need to use the hairpin, you only need to press the button 41 with your hands , the hairpin 4 can be opened, and when the external force disappears, the hairpin 4 resets automatically. The heating element 3 is wrapped by the aluminum plate 5, and the aluminum plate 5 constitutes a heating box, and the heating box and the aluminum tube 3 are connected by plane contact, and the heat transfer is carried out by means of the plane contact, and the efficiency is very high. When the temperature of the heating element 3 is 280 d...

Abstract

The invention discloses a hair curler, which comprises an aluminum tube, wherein a heater is arranged in the aluminum tube; the aluminum tube is elastically and movably connected with a hair clip; the heater is wrapped by an aluminum plate; and the aluminum plate is in planar contact with the aluminum tube. The heater is arranged in the hair curler, a heating box is connected with the aluminum tube through planar contact, heat is transferred in a planar contact mode, and the efficiency is extremely high. When temperature of the heater is 280 DEG C, the temperature to the surface of the aluminum plate is about 250 DEG C. Temperature difference range between the heater and the aluminum plate is narrower, so that a function of difficulty damaging hair quality is achieved; and a temperature sensor is connected with the aluminum tube through direct contact. Temperature control is accurate and reliable, and temperature difference is reduced. Other accessories are not required between a plastic head and the aluminum tube, so that a production process is directly simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to a hair curler, which is mainly used for beauty and hairdressing in families or barber shops. Background technique [0002] At present, in the known hair curlers, the PTC heating element is provided in the hair curler. The PTC heating element is arranged in the inside of the aluminum tube of the hair curler in a suspended manner. The heat of the PTC heating element is transferred to the aluminum tube through the pressing sheet, and the pressing sheet and the aluminum tube are connected by an arc surface. The arc itself is poorly matched, and the heat transfer efficiency is low. The surface temperature of the aluminum tube is about 220, the temperature deviation between the PTC heating element and the aluminum tube is very large, and the large deviation is easy to cause damage to the hair quality. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to provide a hai...
