Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figures 1-4 As shown, this utility model provides a hair styling tool with novel electronic components, including a housing assembly 1, and a motor 8 body, a PCB board 2, and electrical components disposed within the housing assembly 1. The PCB board 2 is disposed between the motor 8 body and the air inlet mesh 102 of the housing assembly 1, and a heat dissipation channel 201 is provided on the PCB board 2 to connect the air inlet of the motor 8 body with the air inlet mesh 102. The electrical components are electrically connected to the PCB board 2, and a receiving space 101 is formed between the mounting shell 3 of the motor 8 body and the housing assembly 1, with some electrical components disposed within the receiving space 101.

[0030] By optimizing the spatial layout within the hair styling tool, the PCB board 2 is positioned between the motor 8 body and the air inlet grille 102 of the housing assembly 1, forming a more compact spatial relationship. A space 101 for accommodating some electrical components is formed between the motor 8 body's mounting shell 3 and the housing assembly 1, providing a more rational and highly integrated mounting position for the electrical components. This effectively reduces the area of ​​the PCB board 2, thereby reducing the overall size of the hair styling tool, making it lighter, easier to carry, and easier to store. Furthermore, a heat dissipation channel 201 is provided on the PCB board 2, connecting the air inlet of the motor 8 body to the air inlet grille 102. This fully utilizes the air intake function of the motor 8 body and introduces external air. The heat dissipation channel 201 effectively removes the heat generated by the PCB board 2 and electrical components during operation, enhancing heat dissipation, extending service life, and improving the overall performance of the hair styling tool.

[0031] As an optional implementation, the electrical components include a motor control chip assembly 10 and a silicon controlled rectifier (SCR) 11, which are disposed on the first side 202 of the PCB board 2 near the air inlet grille 102.

[0032] With this configuration, since the motor control chip assembly 10 and the silicon controlled rectifier 11 will release a lot of heat during operation, placing them near the air inlet 102 allows outside air to be drawn in through the air inlet 102 and carried away through the heat dissipation channel 201, thus improving heat dissipation efficiency.

[0033] The electrical components set on the first side 202 of the PCB board 2 include, but are not limited to, the motor control chip assembly 10 and the silicon controlled rectifier 11. Other small electrical components that also release a lot of heat during operation are preferentially set on the first side 202 of the PCB board 2 in order to facilitate better heat dissipation of the electrical components.

[0034] As an optional implementation, the electrical components also include a heating temperature control sensor and a capacitor assembly. The heating temperature control sensor is connected to the second side 203 of the PCB board 2 via a second connecting harness 13. The capacitor assembly is disposed on the second side 203 of the PCB board 2 and extends into the receiving space 101 in an axial direction parallel to the housing assembly 1. The motor 8 body is connected to the second side 203 of the PCB board 2 via a motor power control harness 14.

[0035] The capacitor assembly extends into the receiving space 101 along an axial direction parallel to the housing assembly 1. This arrangement makes full use of the internal space of the hair styling tool, and the capacitor assembly does not completely occupy the planar space on the PCB board 2, saving space on the PCB board 2 and thus effectively reducing the area of ​​the PCB board 2.

[0036] The electrical components disposed on the second side 203 of the PCB board 2 include, but are not limited to, capacitor assemblies. Other larger electrical components are preferably disposed on the second side 203 of the PCB board 2 in an axially extending manner to optimize the space layout.

[0037] As an optional implementation, the capacitor assembly includes a motor starting capacitor 16, a filter capacitor, and a safety capacitor 15.

[0038] Furthermore, the motor starting capacitor 16, the filter capacitor, and the safety capacitor 15 all extend into the receiving space 101 in an axial direction parallel to the housing assembly 1.

[0039] As an optional implementation, the motor power control harness 14 passes through the mounting housing 3 and connects to the motor body 8.

[0040] As an optional implementation, the electrical components also include a main power switch 4. The mounting housing 3 is provided with a positioning groove 301 for mounting the main power switch 4. The main power switch 4 is connected to the second side 203 of the PCB board 2 through the first connecting wire harness 12, and the housing assembly 1 is provided with a sliding groove 103 for exposing the operation key 401 of the main power switch 4.

[0041] Furthermore, the main power switch 4 extends into the receiving space 101 in an axial direction parallel to the housing assembly 1.

[0042] By moving the main power switch 4 externally and integrating it into the mounting housing 3, the number of electrical components directly mounted on the PCB board 2 is reduced, thereby reducing the area of ​​the PCB board 2. Furthermore, the main power switch 4 extends into the housing space 101, making full use of the internal space of the hair styling tool and improving space utilization.

[0043] The design of the slide 103 allows the user to easily push the operation key 401 to turn the main power switch 4 on or off, controlling the start and stop of the hair styling tool.

[0044] As an optional implementation, the electrical components also include a button control board 5, an indicator light 7, and an adjustment button assembly. The button control board 5 is connected to the second side 203 of the PCB board 2 via a first connecting wire harness 12 and screwed onto the mounting housing 3. The indicator light 7 and the adjustment button assembly are connected to the button control board 5, and the housing assembly 1 has a mounting groove 104 for exposing the indicator light 7 and the adjustment button assembly.

[0045] Furthermore, the button control board 5 is screwed onto the positioning groove 301. This arrangement creates a limiting space for the main power switch 4 between the button control board 5 and the positioning groove 301, ensuring the main power switch 4 is securely mounted between the button control board 5 and the positioning groove 301. The button control board 5 has a notch for the operation key 401, which will not affect the normal operation of the main power switch 4. The button control board 5 is electrically connected to the main power switch 4.

[0046] Operation key 401 is connected to button control board 5 via switch bracket 9.

[0047] The adjustment button assembly includes a fan speed / temperature button 6, preferably a touch button, which allows the user to change the working status of the hair styling tool by operating the fan speed / temperature button 6.

[0048] Indicator light 7 is used to display the current status or working mode of the hair styling tool.

[0049] The button control board 5 is used to receive signals from the wind speed / temperature button 6, transmit the signals to the PCB board 2 through the first connecting wire harness 12, and drive the indicator light 7 to display the current status or working mode of the hair styling tool.

[0050] By moving the button control panel 5, indicator light 7, and adjustment button assembly outward and integrating them onto the mounting housing 3, the number of electrical components directly mounted on the PCB board 2 is further reduced, thereby reducing the area of ​​the PCB board 2. Furthermore, the button control panel 5, indicator light 7, and fan speed / temperature button 6 can be arranged to extend along an axial direction parallel to the housing assembly 1, making full use of the internal space of the hair styling tool and improving space utilization.

[0051] As an optional implementation, the PCB board 2 has a ring structure, and its ring holes are heat dissipation channels 201.

[0052] Furthermore, the PCB board 2 is embedded in the rear shell of the housing assembly 1.

[0053] This design allows for more efficient use of the internal space of the hair styling tools, saving space radially while also enhancing heat dissipation.

[0054] It should be noted that this utility model only improves the layout of the PCB board 2 and electrical components in the hair styling tool, and does not change the specific circuit connection relationship between the PCB board 2, electrical components, and electrical components. The specific circuit connection relationship adopts the conventional design in the prior art, such as power supply, signal transmission and control logic, etc., which will not be elaborated here.
