The first opening is located in the detachment area. The anti-detachment part is adapted to block the wire entering the receiving area from the first opening, so as to limit the wire from detaching from the receiving area under the action of no external force.

[0034] This utility model provides a wire fixing bracket 100, which can be used in electronic devices to fix the conductive wires in the electronic devices, so as to ensure the neatness and stability of the conductive wires. For details, please refer to... Figure 1 and Figure 2In this embodiment, the wire fixing bracket 100 includes a first guide wall 1, a second guide wall 2, a guide end wall 3, and a wire fixing structure 4. The first guide wall 1 and the second guide wall 2 are both arranged in a ring shape, with the first guide wall 1 sleeved on the outside of the second guide wall 2. The guide end wall 3 is connected between the first guide wall 1 and the second guide wall 2. The wire fixing structure 4 is disposed on the guide end wall 3 and includes a wire passage hole 41 and an anti-detachment part 42 disposed in the wire passage hole 41. One side of the wire passage hole 41 has a first opening 411 facing outward. The anti-detachment part 42 divides the wire passage hole 41 into a connected receiving area and a detachment area. The first opening 411 is located in the detachment area. The anti-detachment part 42 is adapted to block the wire entering the receiving area from the first opening 411, so as to limit the wire from detaching from the receiving area under the action of non-external force.

[0035] In this embodiment, the first guide wall 1 and the second guide wall 2 are arranged in a ring shape, so that airflow channels can be formed between the first guide wall 1 and the second guide wall 2, as well as on the inner side of the second guide wall 2. Furthermore, the first guide wall 1 and the second guide wall 2 are connected by the guide end wall 3, which improves the strength between the first guide wall 1 and the second guide wall 2. Moreover, a wire-fixing structure 4 is provided on the guide end wall, allowing the guide wire to extend from the first opening 411 of the wire-passing hole 41 into the wire-passing hole 41. Furthermore, an anti-detachment part 42 is provided within the wire passage hole 41. This anti-detachment part 42 blocks the wire entering the receiving area from the first opening 411, preventing the wire from detaching from the receiving area without external force. This ensures the conductor wire does not swing arbitrarily, such as being detached by airflow or vibrations from the molding device 1000, making the conductor wire more stable. Moreover, when disassembling the circuit board, the conductor wire can be manually removed from the first opening 411 of the wire passage hole 41, making maintenance easier. When the wire fixing bracket 100 is installed within the molding device 1000, it better ensures the stability of the conductor wires within the molding device 1000, resulting in more stable operation and a longer service life for the molding device 1000.

[0036] It is understood that the wire holder 100 can be applied to various electronic devices for fixing the wires in the electronic devices. Preferably, the wire holder 100 is applied to the molding device 1000, such as a hair dryer, to make the wire connection in the hair dryer more secure. For ease of explanation, the following description uses the application of the wire holder 100 to a hair dryer as an example to specifically illustrate the wire holder 100; other devices can be adapted accordingly.

[0037] The wire-fixing bracket 100 can be installed and fixed inside the blower's duct. Since the blower duct is roughly cylindrical, the first guide wall 1 and the second guide wall 2 are also roughly cylindrical. Preferably, the first guide wall 1 is fixedly sleeved inside the blower duct, with the end of the blower duct having the air outlet as the front end, and the guide end wall 3 is positioned near the rear end of the first guide wall 1 and the second guide wall 2. A circuit board structure 300 can be installed inside the blower duct. The circuit board structure 300 is located on the rear side of the guide end wall 3 and is connected to the wire-fixing bracket 100. Electronic devices located in front of the wire-fixing bracket 100, such as a fan or heating structure 400, need to be connected to the circuit board structure 300 through wires. Therefore, the wires can pass through the wire-through hole 41, allowing them to be neatly accommodated within the wire-through hole 41 and better electrically connected to the circuit board structure 300.

[0038] To facilitate the insertion of the conductor wire into the through hole 41, a first opening 411 is provided on one side of the through hole 41. The conductor wire can be inserted into the through hole 41 through the first opening 411, making the insertion operation more convenient compared to a through hole without an opening. However, it is understandable that after the conductor wire is inserted into the through hole 41, it is easy for it to come out of the through hole 41 under the blowing of airflow or vibration during normal operation of the hair dryer. Therefore, by providing an anti-detachment part 42 in the through hole 41, the conductor wire is better prevented from coming out, and when maintenance is required, the conductor wire can also be manually detached from the through hole 41.

[0039] It is understood that the anti-detachment part 42 can be configured in various ways, and any method that forms a certain barrier between the conductor wire housed in the wire passage hole 41 and the first opening 411 is within the protection scope of this utility model. Preferably, the housing area and the detachment area are connected by a first through hole, and a first wire passage channel is formed between the first through hole and the first opening 411. The first wire passage channel is not linearly arranged, so that there is movement resistance between the first through hole and the first opening 411, making it difficult for the conductor wire to move to the first opening 411, thereby restricting the conductor wire and making it difficult for the conductor wire in the wire passage hole 41 to come out.

[0040] Furthermore, combined Figure 1 and Figure 2As shown, the anti-detachment part 42 includes an anti-detachment protrusion 421 protruding from the inner sidewall of the wire passage hole 41. The other end of the anti-detachment protrusion 421 is spaced apart from the inner sidewall of the wire passage hole 41 to form the first through hole. The anti-detachment protrusion 421 forms a receiving area for accommodating the wire and a detachment area communicating with the first opening 411 in the wire passage hole 41. The wire can enter the detachment area from the first opening 411, pass through the first through hole, and enter the receiving area. When the wire is released, under the action of the wire's own deformation force or airflow, the wire cannot automatically pass through the first through hole due to the obstruction of the anti-detachment protrusion 421. Therefore, when the molding device 1000 is working normally, the wire can be properly placed in the wire passage hole 41 to ensure reliable connection with the circuit board structure 300. When it is necessary to remove the wire, the wire can be manually moved to pass through the first through hole and then detached from the first opening 411. This ensures that the conductor is fixed stably and reliably, and is easy to install and remove.

[0041] In one embodiment, if Figure 1 and Figure 2 As shown, the anti-detachment protrusion 421 is arranged in a straight line and is located on the same side of the wire passage hole 41 as the first opening 411. After passing through the first opening 411, the conductor must pass over the anti-detachment protrusion 421 to enter the receiving area, thereby preventing the conductor from coming out directly from the first opening 411.

[0042] In another embodiment, more bends can be formed between the first through hole and the first opening 411, resulting in greater resistance to the wire coming out. Specifically, the anti-detachment protrusion 421 has a first protrusion and a second protrusion connected to each other. The first protrusion protrudes from the inner wall of the wire hole 41 where the first opening 411 is located, and the second protrusion extends laterally from the first protrusion. This makes the movement path of the wire entering the receiving area longer, thereby increasing the resistance to detachment and ensuring a better limiting effect.

[0043] Of course, the anti-detachment part 42 can be configured in ways including but not limited to the above. Any configuration that can confine the wire within the wire hole 41 and facilitate the insertion and removal of the wire should be within the scope of protection of this application.

[0044] The number and position of the wire fixing structure 4 can be adjusted according to the actual circuit board connection status, and are not specifically limited here. Preferably, two sets of the wire fixing structure 4 are provided, and the two sets of the wire fixing structure 4 are symmetrically arranged along the radial direction of the first guide wall 1, so that the conductor wire in the blower can be divided into two parts, which makes it easier to connect and manage the conductor wire.

[0045] Furthermore, the first guide wall 1 is arranged in a non-circular ring shape, with a second opening on one side. The wire fixing structure 4 is arranged corresponding to the second opening, so that the wire can have enough space to pass through, and it is also convenient for the wire fixing bracket 100 to connect with the air inlet of the blower to facilitate the flow of air.

[0046] This utility model also provides a styling device 1000, which can be configured as a hair dryer, curling iron, or straightener, etc. Specifically, in conjunction with Figure 3 As shown, the molding device 1000 includes a housing 200, the aforementioned wire-fixing bracket 100, and a circuit board structure 300. The wire-fixing bracket 100 is disposed within the housing 200. The circuit board structure 300 is connected to the wire-fixing bracket 100 and includes a circuit board and conductive wires. At least a portion of the conductive wires can be snapped into the wire-passing hole 41 of the wire-fixing bracket 100. The circuit board is fixed by the wire-fixing bracket 100, and the conductive wires electrically connected to the circuit board are also regulated and restricted, making the operation of the circuit board structure 300 more stable, thereby ensuring the working performance of the molding device 1000.

[0047] Furthermore, a first air duct is formed between the first guide wall 1 and the second guide wall 2 of the wire fixing bracket 100, and a second air duct is formed on the inner ring side of the second guide wall 2. A ventilation hole is provided on the guide end wall 3 of the wire fixing bracket 100, and the ventilation hole connects the first air duct and the second air duct. The molding device 1000 also includes a fan, which can draw external airflow into the housing 200. The air outlet of the fan is connected to the first air duct. Specifically, the air outlet of the fan is opposite to the second opening on the first guide wall 1, so that airflow can enter the first air duct from the second opening on the first guide wall 1. A portion of the airflow can pass through the ventilation hole to enter the gap between the guide end wall 3 and the circuit board, and flow along the gap to enter the second air duct, allowing the airflow to carry away some of the heat from the circuit board and dissipate heat from the circuit board.

[0048] Furthermore, the molding device 1000 also includes a heating structure 400, which can be configured as a heating wire or a heating plate. The heating structure 400 can also be annular to provide a heating channel for airflow. The circuit board is located at the rear end of the second guide wall 2 along its axial direction, and the heating structure 400 is located at the front end of the second guide wall 2 along its axial direction. An airflow channel is formed within the housing 200. The first air duct is connected to the air inlet side of the airflow channel, and the second air duct is connected to the air outlet side of the airflow channel. After entering the first air duct through the airflow channel, the airflow flows through the ventilation hole to the circuit board and then flows from the second air duct toward the heating structure 400. This allows the airflow to flow to the heating structure 400 after passing through the circuit board, which on the one hand dissipates heat from the circuit board, and on the other hand improves heating efficiency, making the molding device 1000 more energy-efficient.

[0049] The molding device 1000 provided by this utility model, through the fixed wire bracket 100, can guide the airflow, so that part of the cold airflow entering the molding device 1000 can flow through the circuit board, which can better realize the heat dissipation of the circuit board structure 300, and conduct the heat dissipation airflow to the heating structure 400, making the heating efficiency of the molding device 1000 higher. On the other hand, it can straighten the wires on the circuit board, making the connection between the wires and the circuit board more stable and reliable, thereby ensuring the stability of the circuit board structure 300, making the working performance of the molding device 1000 better, and extending the service life of the molding device 1000.

[0050] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
