Technical Field

[0001] The utility model relates to the field of charging equipment, in particular to a charging base for a hair straightening comb. Background Art

[0002] A hair straightening comb is a hairstyling tool primarily used for straightening, drying, and conditioning women's hair. Existing hair straightening combs typically require a power cord for use, which can interfere with the power cord and hinder user experience. Because hair straightening combs are typically cylindrical in shape, they are prone to rolling when charged directly with a charging cable, leading to unstable charging. Utility Model Content

[0003] The utility model solves the problems raised in the background art by arranging a Type-C charging connector in a U-shaped charging base that is suitable for most hair straightening combs, so that the hair straightening comb can be disconnected from the power cord and can be stably charged on the base for wireless use.

[0004] The technical solution adopted by this utility model is:

[0005] A straightening comb charging base includes: a main shell, a circuit board, and a bottom cover, which are installed from top to bottom. The circuit board is provided with a power transmission connector. The inner side of the main shell is arranged in a U-shaped structure. The bottom of the main shell is provided with a connector embedding hole. When the circuit board is installed between the main shell and the bottom cover, the power transmission connector protrudes from the outside of the connector embedding hole. The power transmission connector is a Type-C connector.

[0006] A limiting convex strip is provided on the inner side of the main shell.

[0007] The circuit board is provided with a charging interface, and the outer side of the main shell is provided with an interface embedding hole.

[0008] A button embedding hole is provided on the main housing, and a switch button is provided in the button embedding hole.

[0009] A key connector is provided on the circuit board, and the switch key is connected to the key connector.

[0010] The beneficial effects of the present invention are as follows: through the structural setting of the U-shaped base, the charging base can be adapted to most models of straightening combs, and the straightening comb set on the base can be charged stably, avoiding problems such as rolling deviation leading to charging interruption; using the Type-C connector as the charging connector improves the charging efficiency and avoids the problem of the traditional USB connector being inserted in the right or wrong direction.

[0019] The structure and function of the present utility model are described below with reference to the accompanying drawings.

[0020] like Figures 1 to 7 , a charging base for a hair straightening comb, whose structure includes a main shell 1, a circuit board 2 and a bottom cover 3 installed from top to bottom. The interior of the main shell 1 is arranged in a U-shaped structure, and the U-shaped structure enables the base to adapt to the bottom of most hair straightening combs. Through the structural setting of the U-shaped base, the charging base can adapt to most models of hair straightening combs, and the hair straightening comb set on the base can be charged stably, avoiding problems such as rolling deviation leading to charging interruption. A connector hole 13 is provided at the bottom of the main shell 1. When the circuit board 2 is installed between the main shell 1 and the bottom cover 3, the power transmission connector 21 protrudes from the outside of the connector hole 13. The power transmission connector 21 is a Type-C connector. As a charging connector, the Type-C connector improves the charging efficiency and avoids the problem of the traditional USB connector being inserted in the right and wrong direction.

[0021] To further stabilize the position of the hair straightening comb during charging, a limiting ridge 11 is provided on the inner side of the main housing 1. As a preferred embodiment of the present invention, the present invention has a total of five limiting ridges, which respectively play an auxiliary supporting role on the back, front and sides of the hair straightening comb, thereby stabilizing the position of the hair straightening comb during charging.

[0022] The circuit board 2 is also provided with a charging port 22, and the outer side of the main housing 1 is provided with an interface hole 14. When the circuit board 2 is installed between the main housing 1 and the bottom cover 3, the charging port 22 is provided at the interface hole 14. The charging port 22 is used to connect with an external charging cable and charging plug to direct external current into the circuit board 2, and output it through the circuit board 2 to the power transmission connector 21, ultimately charging the hair straightening comb. As a preferred embodiment of the present invention, the charging port 22 is a Type-C interface.

[0023] The main housing 1 is provided with a button hole 12, and a switch button 4 is located within the button hole 12. The switch button 4 is used to turn the charging function of the charging base on and off. The circuit board 2 is provided with a button connector 23, and the switch button 4 is electrically connected to the button connector 23. The button connector 23 is provided with a mechanical switch that is linked to the switch button 4. When the switch button 4 is pressed, the button connector 23 switches from the disconnected state to the connected state. At this point, the charging circuit in the circuit board 2 operates normally, and the hair straightening comb can be charged at the hair straightening comb charging base. Pressing the switch button 4 again switches the button connector 23 back from the connected state to the disconnected state, disconnecting the circuit board 2 from power, and the hair straightening comb cannot be charged at the hair straightening comb charging base. The switch button 4 prevents the hair straightening comb from overcharging. When fully charged, the charging base can also automatically disconnect the charging function, allowing the hair straightening comb to be used as a normal hair straightening comb base.

[0024] The above description describes the structure, connection method, main embodiments, and advantages of the present invention. It should be noted that the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the technical solution of the present invention, or any direct application of the concept and technical solution of the present invention to other situations without modification, are all within the scope of protection of the present invention. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
