Description

Technical Field

[0001] This utility model relates to the field of hair dryer manufacturing technology, specifically to a wiring structure used on a hair dryer handle. Background Technology

[0002] Hair dryers are essential household appliances used for quickly drying hair and styling. Common hair dryers resemble a "T" or "7" shape, consisting of a handle and a main body. The handle can be foldable or non-foldable. This design results in a large size, making them inconvenient to carry. Combining these two main units into one would significantly reduce the size of the hair dryer. As disclosed in Chinese Patent CN112189971A, a handheld stick-type hair dryer and a separate converging airflow device are arranged sequentially along the main body axis, including the heating element, circuit controller box, and bladeless fan. However, because the circuit controller box is located in the middle and the power supply is located below the bladeless fan, and all components need to be connected by wires, the wiring of the circuit controller box, which is between the bladeless fan and the heating element, affects the airflow effect. Furthermore, the internal wiring is chaotic. For example, if the power supply wire needs to be connected to the circuit controller box, it must pass through the bladeless fan. The circuit controller box's wiring also needs to connect to both the bladeless fan and the heating element, resulting in a chaotic internal wiring situation that significantly impacts subsequent maintenance. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wiring structure for use on the handle of a hair dryer.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A wiring structure for use on a hair dryer handle includes a housing, which includes a first housing and a second housing that cooperate with each other, forming a heating chamber, a fan chamber and a circuit board chamber arranged sequentially along the axis of the housing. A wiring groove is provided on any one or both sides of the housing, and the front and rear ends of the wiring groove are respectively provided with a first wiring hole communicating with the fan chamber and a second wiring hole communicating with the circuit board chamber.

[0006] The first housing is provided with a switch mounting slot, and the wiring groove is located on both sides of the switch mounting slot.

[0007] The first housing has a recessed section on one or both sides to form a wiring groove.

[0008] The first housing is provided with a first wire clamp on any one or both sides.

[0009] The switch mounting slot is provided with a switch mounting bracket, which is engaged with the first housing.

[0010] The switch mounting bracket extends downwards on both sides to form a second cable clamp.

[0011] The second wire clip is arc-shaped and extends along the contour of the housing.

[0012] A mesh partition is provided between the fan cavity and the circuit board cavity.

[0013] The end of the housing is configured as an air inlet chamber, and a filter cup is provided in the air inlet chamber. The end of the housing is also provided with a detachable air inlet cover, which, when fitted with the housing, fixes the filter cup between the two.

[0014] The beneficial effects of this utility model are as follows: By moving the fan forward between the heating element and the circuit board, the wiring direction is aligned. The first and second housings cooperate with each other, and wiring grooves are formed on both sides or one side of the outer side of the housings. The wires of the circuit board are led out from the first wiring hole, run on the outside, and then re-enter the housing at the second wiring hole to connect with the fan and heating element. This avoids the wires passing directly through the fan and reduces the obstruction of the fan's flow path by the internal wiring. At the same time, the design of the wiring grooves makes the wiring neater, prevents the wires from being messy, facilitates subsequent maintenance, and reduces safety hazards.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0022] like Figure 1 and Figure 2 As shown, a wiring structure for a hair dryer handle is located inside the hair dryer body. The wiring structure includes a housing, which is equivalent to the internal housing of the hair dryer body. A corresponding outer shell is also provided on its outer side for a more aesthetically pleasing overall appearance. The housing includes a first housing 100 and a second housing 200 that cooperate with each other. In this embodiment, the first housing 100 and the second housing 200 are snap-fitted together. Both are semi-circular and hollow, forming a columnar structure. Between them, a heating chamber 10, a fan chamber 20, and a circuit board chamber are sequentially arranged along the axial direction of the housing. 30, and each cavity is provided with a corresponding partition to restrict the heating element, fan and control circuit board fixed in the heating cavity 10, fan cavity 20 and circuit board cavity 30 respectively. A wiring groove 500 is provided on any one or both sides of the housing. The length of the wiring groove is adapted to the length of the fan cavity. The front and rear ends of the wiring groove 500 are respectively provided with a first wiring hole 1000 communicating with the fan cavity 20 and a second wiring hole 2000 communicating with the circuit board cavity 30. Through the wiring hole, the internal wiring is turned from the inside to the outside and fixed in the wiring groove, so that the wiring is more neat.

[0023] The fan is directly connected to the heating element, allowing the airflow driven by the fan to enter the heating chamber without any loss and be heated by the heating element.

[0024] like Figure 1 As shown, the first housing 100 is provided with a switch mounting slot 120, and the wiring slot 500 is located on both sides of the switch mounting slot 120. The switch mounting slot is used to install a switch assembly, which is used to control the internal control circuit board. It is mounted on the switch mounting bracket 300 and fixedly connected to the first housing 100 through the switch mounting bracket 300.

[0025] like Figure 3 As shown, a wiring groove 500 is formed by recessing one or both sides of the first housing 100. The recess creates a certain gap for wiring, preventing the wire from being directly clamped by the first housing and the outer shell, which could lead to wire damage.

[0026] A first wire-holding component 110 is provided on any one or both sides of the first housing 100. The first wire-holding component extends directly upward from the first housing, along the outer contour of the first housing, and forms a gap with the wiring groove. This gap allows the wire to be arranged within it. The first wire-holding component makes the wiring neater and closer to the wiring groove. Figure 4 As shown in the figure, wiring channels are provided on both sides in this embodiment to accommodate the four wires of the fan and the three wires of the heating element. At the same time, when adding corresponding functional components, such as negative ion controllers and NTC, additional wires are required, such as two wires for negative ion controllers and two wires for NTC. Therefore, wiring channels are provided on both sides to divide the 11 wires into left and right sides for more reasonable wiring.

[0027] The switch mounting slot 120 is provided with a switch mounting bracket 300, and the switch circuit board 50 is mounted on the switch mounting bracket. The switch mounting bracket 300 is snapped into the first housing 100. It utilizes multiple inverted buckles on the lower side of the switch mounting bracket 300 to engage with the corresponding snaps on the first housing, thus completing the snap-fit ​​between the two and assembling them into one unit. At the same time, the switch circuit board 50 can be directly electrically connected to the control circuit board, that is, the interface of the switch circuit board is located on the upper end of the control circuit board, so that the two can be directly connected, eliminating the corresponding wiring requirements.

[0028] like Figure 5 As shown, the switch mounting bracket 300 extends downward on both sides to form a second wire clamping member 310. The second wire clamping member 310 is arc-shaped and extends along the contour of the housing. The second wire clamping member 310 is located on both sides of the first wire clamping member, further binding the wires and ensuring the neatness of the wires.

[0029] A mesh partition 60 is provided between the fan chamber 20 and the circuit board chamber 30. The mesh partition design can form a partition between the fan chamber and the circuit board chamber, which can prevent the wires of the control circuit board from accidentally entering the fan chamber. At the same time, the mesh partition allows the air entering through the circuit board chamber to pass evenly through the mesh partition into the fan chamber, and then be quickly blown by the fan to the heating chamber, heated by the heating element, and blown out as hot air.

[0030] The end of the housing is configured as an air inlet chamber 40, and a filter cup 600 is provided at the air inlet chamber 40. The end of the housing is also provided with a detachable air inlet cover 400. After the air inlet cover 400 is engaged with the housing, the filter cup 600 is fixed between the two.

[0031] The filter cup includes a support and a filter screen covering the support. The whole can filter the air entering from the outside to prevent hair and dust from entering the hair dryer body. The air inlet cover and the housing are connected by threads or snaps. In this embodiment, the air inlet cover and the housing are fixedly connected by magnetic attraction. When replacing the filter screen, the air inlet cover can be removed directly to replace the filter cup. At the same time, the magnetic attraction makes installation and disassembly more convenient.

[0032] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
