Description

Technical Field

[0001] This utility model relates to the technical field of hair dryers, and in particular to a main control board mounting structure for a hair dryer. Background Technology

[0002] A hair dryer consists of a set of resistance wires and a high-speed motor. The high-speed motor contains fan blades that blow air. When powered on, the resistance wires generate heat, and the air blown by the fan passes through the resistance wires, turning into hot air. If only the small fan is running, but the resistance wires are not heated, then only air will be blown out, not hot air.

[0003] Current products on the market use positioning holes and screws to fix the main control circuit board of the blower. The product structure design is complex, making the circuit board installation process complicated and resulting in relatively high assembly costs. In addition, the use of metal materials such as screws to fix the circuit board requires fixing positions and installation restricted areas, resulting in low overall utilization of the circuit board. Furthermore, during the installation process, metal materials may loosen, leading to potential electrical safety hazards and other faults.

[0004] In summary, there is a need for a simple and easy-to-install main control board mounting structure for hair dryers. Utility Model Content

[0005] This invention aims to overcome the shortcomings of existing technologies, such as complex circuit board installation processes leading to relatively high assembly costs, the need for fixing the circuit board with screws and other metal materials requiring fixed positions and restricted installation areas, resulting in low overall utilization of the circuit board, and the potential for metal materials to loosen during installation, which could cause electrical safety hazards. The invention provides a simple and convenient main control board mounting structure for a hair dryer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A main control board mounting structure for a hair dryer includes:

[0008] The handle housing consists of a front handle housing and a rear handle housing that are fitted together and interlocked with each other.

[0009] The main control board is located inside the handle housing;

[0010] The main control board slot is located on the inner wall of the front shell of the handle. The main control board slot matches one side of the main control board and the two are inserted into each other.

[0011] The main control board positioning groove is located on the inner wall of the handle rear shell, and the main control board positioning groove matches the other side of the main control board and the two are inserted into each other.

[0012] During installation, first insert one side of the main control board into the main control board slot on the front shell of the handle. Then, align the main control board positioning slot on the rear shell of the handle with the other side of the main control board and insert it. When the front and rear shells of the handle are fully engaged, the main control board is fixed between the main control board slot and the main control board positioning slot. This utility model adopts a plug-in installation method, which maximizes the utilization of the main control board layout, simplifies the structure, and streamlines the installation process. Installation is simple, fast, and convenient, eliminating the need for traditional screw fixing. It eliminates the need for positioning holes and screw installation, saving on related accessories and avoiding potential safety risks caused by the loss of some materials during installation.

[0013] Preferably, the opening of the main control board positioning slot is provided with an insertion guide angle. This guide angle design improves the smoothness of the interlocking between the other side of the main control board and the main control board positioning slot, making operation simple and convenient, saving time and effort, and allowing for partial blind assembly during assembly.

[0014] Preferably, the main control board is equipped with a wire connector, and the two ends of the handle housing are respectively provided with component wires and power wires, both of which are connected to the wire connector. After the main control board is inserted into the main control board slot on the front shell of the handle, the component wires and power wires are connected to the wire connector on the main control board and soldered to fix it, thereby controlling the operation of the hair dryer components. The structure is simple and easy to install.

[0015] Preferably, a component wire clamping plate and a power wire clamping plate are installed inside the handle housing. The component wires are fixed to the inner wall of the handle housing via the component wire clamping plate, and the power wires are fixed to the inner wall of the handle housing via the power wire clamping plate. The component wire clamping plate and the power wire clamping plate limit and fix the component wires and power wires, improving the wire fixing effect and ensuring that the wires remain stable within the handle space during the operation of the hair dryer.

[0016] Preferably, the main control board is equipped with a safety capacitor and a thermistor, both of which are electrically connected via wires and a connector. A negative ion module is fixed inside the handle housing and is also electrically connected via wires and a connector. The structure is simple and the connection is convenient.

[0017] Preferably, the main control board is provided with several switch contacts, and control buttons corresponding to the positions of the switch contacts are installed on the side wall of the handle housing. Operators can control the hair dryer by pressing the control buttons to operate the main control board inside the phone housing. The structure is simple and the operation is convenient.

[0018] The beneficial effects of this utility model are: the use of plug-in installation makes the main control board layout highly efficient, the structure simple, and the installation steps simplified, making the installation work simple, fast, and convenient; it abandons the traditional screw fixing method, eliminating the need for positioning holes and screw installation, saving related accessories and avoiding the safety risks that may be caused by the omission of some materials during the installation process; it improves the smoothness of the plug-in connection, making the operation simple and convenient, saving time and effort, and allowing partial blind installation during assembly; it improves the wire fixing effect; and it is convenient to operate and control.
