[0028] The hair straightener of the preferred embodiment of the utility model is as follows Figure 1-5 As shown, the hair straightener includes a hair straightener body 10, one end of which forms a curling end 101, and the other end forms a handheld end 102. The hair straightener also includes a protective cover 20 that is detachably mounted on the curling end 101 to prevent people from being burned. The handheld end 102 is provided with a first switch 30 for controlling the on and off of the control circuit of the hair straightener. When the protective cover 20 is assembled in place, the first switch 30 is triggered and the control circuit of the hair straightener body 10 is disconnected through the first switch 30. The utility model has a simple overall structure, is practical and convenient, and can prevent the curling end 101 from scalding the user, and after the protective cover 20 is assembled in place, the first switch 30 can be synchronously triggered to cut off the circuit, so as to prevent the user from forgetting to close it after use and directly installing the protective cover 20 to cause the device to be burned.

[0029] In this embodiment, the first switch 30 includes a sliding key 31 axially slidably arranged on the handheld end 102, and a sliding switch body 32 arranged on the circuit board 200 inside the hair straightener body 10.

When assembled in place, the protective cover 20 pushes the sliding key 31 into place and closes the sliding switch body 32, thereby cutting off the control circuit, so as to realize the shutdown of the hair straightener body 10 while the protective cover 20 is assembled, so as to prevent the user from forgetting to shut down the device and causing the device to be burned.

[0030] In this embodiment, a positioning step 50 adapted to the protective cover 20 is formed on the side wall of the hair curling end 101, and a slide groove 60 for the sliding key 31 to slide is provided on the handheld end, and the slide groove 60 is directly connected to the positioning step 50. In the initial state, the sliding key 31 extends out of the slide groove 60 toward one end of the step, that is, in this state, the protective cover 20 is in a non-assembled state. By sliding the sliding key 31 set in the slide groove 60, the user can turn on the first switch 30 after removing the protective cover 20 and start heating the hair straightener body 10 to facilitate hair curling.

[0031] In this embodiment, the hair straightener further comprises an elastic reset member 70 for resetting the sliding key 31 to the initial state, and the elastic reset member 70 is arranged inside the handheld end and axially arranged on the inner wall thereof, so as to facilitate synchronously starting the hair straightener body 10 after opening the protective cover 20, thereby reducing the user's operation.

[0032] In this embodiment, the hair straightener body 10 includes two opposite shells 11, both of which are semi-cylindrical structures and the opposite side walls are planes. One end of the shell 11 is a curling end 101, and the other end is a handheld end 102. The two handheld ends 102 are rotatably connected. In addition, for ease of use, a torsion spring (not shown) is provided on the handheld end 102 to keep the two shells 11 in an open state. The hair straightener also includes a heating plate assembly 80 provided on the curling end 101, and two heating assemblies are provided corresponding to the two heating ends. When assembled in place, the two curling ends 101 and the heating plate assembly 80 are both located in the protective cover 20 to achieve the overall covering of the heating end to prevent the high-temperature heating assembly from being exposed to the outside and scalding people. Among them, the first switch 30 is provided on any one of the two shells 11 and is located on the handheld end 102, so that the user can conveniently operate the sliding key 31 of the first switch 30 when holding it.

[0033] In this embodiment, a heat insulating gap 90 is provided on the housing 11 around the heating plate assembly 80 to reduce the heat transferred from the heating assembly to the housing 11 and prevent the housing 11 from deforming.

[0034] In this embodiment, comb teeth 100 are provided on both sides of the heating plate assembly 80 of the housing 11 to guide and disperse the hair to ensure that the hair is evenly heated, and also to act as a comb to straighten the hair during the hair straightening process.

[0035] In this embodiment, the housing 11 is provided with a mounting groove 110 for mounting the heating plate assembly 80. The heating plate assembly 80 includes a heat conducting plate 81 in direct contact with the hair, a heating element 82 disposed on a side wall of the heat conducting plate 81 away from the side in contact with the hair, a heat insulating member 83 disposed on a side of the heating element 82 away from the heat conducting plate 81, and a fixing plate 84 disposed on a side of the heat insulating member 83 away from the heat conducting plate 81. The fixing plate 84 is detachably disposed on the inner wall of the mounting groove 110. The heat conducting plate 81 is provided with a receiving groove 120. The heating element, the heat insulating member 83 and the fixing plate 84 are all located in the receiving groove 120. The heat conducting plate 81 is also provided with a bending portion (not shown) for pressing the fixing plate 84 against the bottom surface of the receiving groove 120. Specifically, the heat conducting plate 81 is formed by stamping a baked ceramic steel sheet, and of course, it can also be other metal plates with good thermal conductivity.

[0036] When assembling the heating plate assembly 80, the heating element 82 is placed inside the ceramic steel sheet. The heating element 82 is a conventional resistance heating element in the shape of a thin sheet. Then the heat insulating member is attached to the heating element 82, and then the fixing plate 84 is pressed into the receiving groove 120. The fixing plate 84 is pressed into the receiving groove 120 through the bending portion. Among them, the fixing plate 84 is fixed to the bottom surface of the receiving groove 120 by screws 190, and a silicone cushion 180 is provided between the fixing plate 84 and the bottom surface of the receiving groove 120, so that the heating plate assembly has a certain buffer stroke when perming and straightening hair, and does not easily damage the hair. In addition, a temperature control sensor 300 electrically connected to the circuit board is embedded on a side wall of the fixing plate close to the heating element, so as to form a closed-loop control to avoid excessive temperature rise.

[0037] The circuit board 200 of the hair straightener is arranged inside the handheld end 102, and the handheld end 102 is also provided with a battery 130 electrically connected to the circuit board 200. In order to increase the battery life, the handheld end 102 equipped with the battery 130 is provided with a recessed portion 140 facing the other handheld end 102 and adapted to the battery 130. The inner cavity of the recessed portion 140 and the inner cavity of the handheld end 102 integrated therewith are used to install the battery 130 together. Accordingly, a avoidance groove 150 adapted to the recessed portion 140 is provided on the other handheld end 102, so that the two shells 11 can fit tightly after closing. Correspondingly, a charging port 170 for charging the battery is provided at the tail of the handheld end.

[0038] In this embodiment, the hair straightener body 10 and the protective cover 20 are both cylindrical, and the two shells 11 are fitted into the cylindrical shape to improve the feel and aesthetics of the product.

[0039] In this embodiment, the handheld terminal 102 is provided with a second switch 160 for controlling the on and off of the control circuit of the hair straightener. The second switch 160 is connected in series with the first switch 30 to further reduce the risk of the heating component being accidentally turned on and ensure safety of use.

[0040] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
