Description

Technical Field

[0001] The present application relates to the technical field of hair dryers, and in particular to a handle and a hair dryer. Background Art

[0002] After washing hair, when people need to wash, sleep or go out, it takes a lot of time to dry hair naturally or with a low-speed hair dryer. High-speed hair dryers facilitate people's lives, shorten the time people spend drying their hair, and facilitate people's lives. At present, in order to be able to blow out wind of different temperatures, high-speed hair dryers are usually composed of a group of electric heating wires and a small fan. If only the small fan rotates and the electric heating wire does not work, the high-speed hair dryer can only blow out cold air. When the electric heating wire and the small fan work at the same time, the electric heating wire assembly generates heat, and the wind blown out by the fan passes through the electric heating wire to become hot air.

[0003] At present, a hair dryer generally includes a hair dryer and a handle. The heating mechanism and the PCB circuit board are placed in the hair dryer, and the fan assembly is placed in the handle, or the heating mechanism, the PCB circuit board and the fan assembly are all placed in the hair dryer, and the handle is only used for gripping. The above-listed arrangement of the components of the hair dryer will result in a large height (or thickness) of the hair dryer, and thus make the overall thickness of the hair dryer larger, which is not conducive to the miniaturized design of the hair dryer, and is also not convenient for the storage and use of the hair dryer. Utility Model Content

[0004] In order to solve the above problems, the present application provides a handle and a hair dryer, which are cleverly designed, and the arrangement positions of various components are reasonable, thereby reducing the thickness of the hair dryer, reducing the noise of the hair dryer, and improving the user experience. The technical solutions adopted in the present application are as follows:

[0005] A handle, comprising a housing, a control key, a PCB circuit board and a fan assembly.

[0006] The PCB circuit board and the fan assembly are arranged in the shell, and the control key is arranged outside the shell. The PCB circuit board, the fan assembly and the control key are arranged in sequence along the length direction of the shell. The PCB circuit board is located at the end of the inner cavity of the shell. An air inlet is opened on the shell, and the position of the air inlet corresponds to the position of the PCB circuit board.

[0007] A shielding portion is provided at the end of the shell, the shielding portion is adjacent to the air inlet, and the shielding portion is used to shield one end of the PCB circuit board.

[0008] By arranging the PCB circuit board at the end of the handle, on the one hand, the volume of the hair dryer is reduced and the thickness of the hair dryer is reduced. On the other hand, the PCB circuit board has little effect on the airflow, which is beneficial to reducing the noise generated when the airflow flows through the channel in the handle; the PCB circuit board, the fan assembly and the control key are arranged in sequence along the length direction of the shell, which is convenient for the user to operate the control key during use. At the same time, the positions of the components in the handle are arranged reasonably, so that the center of gravity of the handle is biased toward the end of the handle. After the handle is connected to the hair dryer (or other components), the center of gravity of the entire hair dryer is located at the gripping part of the handle. The user's arm is not easily fatigued when using it, which improves the use experience; by arranging a shielding part, one end of the PCB circuit board is shielded, so that the air inlet is not facing the end of the PCB circuit board close to the end of the handle, thereby reducing the probability of airflow turbulence at the end of the PCB circuit board, thereby reducing the noise generated when the airflow flows through the PCB circuit board.

[0009] In some embodiments, the handle further includes two rectifying members, each of which is provided with evenly distributed rectifying holes, and the two rectifying members are disposed between the PCB circuit board and the fan assembly, with a preset distance between the two rectifying members.

[0010] By providing two rectifying parts, the rectifying effect can be improved, the airflow noise can be reduced, and the airflow velocity can be ensured to be within a reasonable range.

[0011] In some embodiments, the shape of the rectifying hole is a regular hexagon. Compared with rectifying holes in circular, square and other shapes, when the rectifying hole is a regular hexagon, the area ratio of the opening on the rectifying member can be increased, the blocking effect of the rectifying member on the airflow can be reduced, and the rectifying effect can be improved.

[0012] In some embodiments, the housing includes a first upper shell, a second upper shell and a lower shell, the first upper shell and the second upper shell are arranged in sequence along the length direction of the handle, the control key is arranged outside the second upper shell, the fan assembly is arranged in the space enclosed by the second upper shell and the lower shell, and the PCB circuit board is arranged in the space enclosed by the first upper shell and the lower shell.

[0013] By providing the first upper shell, the second upper shell and the lower shell, the number of components of the shell is reduced, thereby simplifying the shell assembly process, improving the integrity of the shell, and reducing the risk of shell damage.

[0014] In some embodiments, the second upper shell includes a same-diameter section, a transition section, and an inner offset section which are sequentially connected along the length direction of the handle, the same-diameter section is adjacent to the first upper shell, and the inner offset section is offset from the same-diameter section so that the size of the space enclosed by the inner offset section and the lower shell is smaller than the size of the space enclosed by the same-diameter section and the lower shell, and the control key is arranged on the transition section and / or the inner offset section.

[0015] The inner staggered section and the same-diameter section are staggered with each other, which provides installation space for the control keys while ensuring that the overall radial size of the handle remains basically unchanged; the setting of the transition section not only allows the airflow to flow smoothly, but also increases the flow rate of the airflow.

[0016] In some embodiments, a wiring groove is provided on the outer side of the second upper shell, and a clearance gap is provided on the first upper shell. The wiring groove and the clearance gap are used to lay out the wires between the PCB circuit board and the control keys.

[0017] Compared with wiring inside the outer shell, arranging the wires between the PCB circuit board and the control keys in the wiring groove on the outside of the second upper shell can improve the convenience of wiring on the one hand, and reduce the influence of the wires on the airflow and reduce the airflow noise on the other hand.

[0018] In some embodiments, a first connecting ear is provided at one end of the first upper shell close to the second upper shell, and a second connecting ear is provided at one end of the second upper shell close to the first upper shell, the first connecting ear and the second connecting ear overlap with each other, and the first upper shell and the second upper shell are fixed to the lower shell together by the same screw passing through the first connecting ear and the second connecting ear.

[0019] By designing that the first connecting ear and the second connecting ear overlap each other, the first upper shell and the second upper shell can be fixed to the lower shell together with the same screw. Compared with fixing the first upper shell and the second upper shell to the lower shell separately, the fixing procedure of the first upper shell and the second upper shell to the lower shell is saved, thereby improving the assembly efficiency of the shell.

[0020] In some embodiments, the fan assembly is provided with a vibration-damping sleeve. By providing the vibration-damping sleeve, the vibration-damping sleeve can absorb the vibration energy generated when the fan assembly is working, reduce the vibration energy transmitted to the housing, and play a role in reducing vibration noise and handle vibration.

[0021] In some embodiments, a filter cover is provided at the end of the handle, and the filter cover covers the outside of the air inlet. By providing the filter cover, debris can be prevented from entering the air inlet, reducing the risk of damage to the PCB circuit board and the fan assembly.

[0022] On the other hand, the present application provides a hair dryer, comprising the aforementioned handle.

[0046] A hair dryer generally includes a hair dryer 14 and a handle. The heating mechanism and PCB circuit board 3 of a traditional hair dryer are placed in the hair dryer 14, and the fan assembly 4 is placed in the handle, or the heating mechanism, PCB circuit board 3 and fan assembly 4 are all placed in the hair dryer 14, and the handle is only used for gripping. The above arrangement of the components of the hair dryer is not conducive to the miniaturized design of the hair dryer, nor is it convenient for the storage and use of the hair dryer.

[0047] To solve the above problems, refer to Figure 1-Figure 5The present application provides a handle, including a shell 1, a control key 2, a PCB circuit board 3 and a fan assembly 4; the PCB circuit board 3 and the fan assembly 4 are arranged in the shell 1, and the control key 2 is arranged outside the shell 1. The PCB circuit board 3, the fan assembly 4 and the control key 2 are arranged in sequence along the length direction of the shell 1, the PCB circuit board 3 is located at the end of the inner cavity of the shell 1, and an air inlet 5 is opened on the shell 1, and the position of the air inlet 5 corresponds to the position of the PCB circuit board 3; a shielding portion 6 is provided at the end of the shell 1, and the shielding portion 6 is adjacent to the air inlet 5, and the shielding portion 6 is used to shield one end of the PCB circuit board 3.

[0048] In this embodiment, by arranging the PCB circuit board 3 at the end of the handle, on the one hand, the volume of the air cylinder 14 is reduced, and the thickness of the air cylinder 14 is reduced. On the other hand, the PCB circuit board 3 has little effect on the airflow, which is beneficial to reducing the noise generated when the airflow flows through the channel in the handle; the PCB circuit board 3, the fan assembly 4 and the control key 2 are arranged in sequence along the length direction of the shell 1, which is convenient for the user to operate the control key 2 during use. At the same time, the positions of the components in the handle are arranged reasonably, so that the center of gravity of the handle is biased toward the end of the handle. After the handle is connected to the air cylinder 14 (or other components), the center of gravity of the entire hair dryer is located at the gripping part of the handle. The user's arm is not easily fatigued when using it, which improves the user experience; by arranging the shielding part 6, one end of the PCB circuit board 3 is shielded, and the air inlet 5 is not facing the end of the PCB circuit board 3 close to the end of the handle, thereby reducing the probability of turbulence of the airflow at the end of the PCB circuit board 3, thereby reducing the noise generated when the airflow flows through the PCB circuit board 3.

[0049] refer to Figure 2 , Figure 3 , Figure 5 In one embodiment, the handle further includes two rectifying members 7, the rectifying members 7 are provided with evenly distributed rectifying holes, the two rectifying members 7 are arranged between the PCB circuit board 3 and the fan assembly 4, and there is a preset distance between the two rectifying members 7.

[0050] It is worth noting that by providing two rectifying members 7, the rectifying effect is improved, the airflow noise is reduced, and the airflow velocity is ensured to be within a reasonable range. The preset spacing between the two rectifying members 7 is preferably 10 mm.

[0051] In one embodiment, the shape of the rectifying hole is a regular hexagon. It is understandable that, compared with rectifying holes in circular, square and other shapes, when the rectifying hole is a regular hexagon, the area ratio of the opening on the rectifying member 7 can be increased, the blocking effect of the rectifying member 7 on the airflow can be reduced, and the rectifying effect can be improved.

[0052] refer to Figure 1-Figure 5In one embodiment, the housing 1 includes a first upper shell 01, a second upper shell 02 and a lower shell 03. The first upper shell 01 and the second upper shell 02 are arranged in sequence along the length direction of the handle. The control key 2 is arranged outside the second upper shell 02. The fan assembly 4 is arranged in the space enclosed by the second upper shell 02 and the lower shell 03. The PCB circuit board 3 is arranged in the space enclosed by the first upper shell 01 and the lower shell 03.

[0053] It is understandable that by providing the first upper shell 01, the second upper shell 02 and the lower shell 03, the number of components of the shell 1 is reduced, thereby simplifying the assembly process of the shell 1, improving the integrity of the shell 1, and reducing the risk of damage to the shell 1.

[0054] refer to Figure 1-Figure 3 , Figure 5 In one embodiment, the second upper shell 02 includes a same-diameter section 021, a transition section 022 and an inner offset section 023 which are connected in sequence along the length direction of the handle, the same-diameter section 021 is adjacent to the first upper shell 01, and the inner offset section 023 is offset from the same-diameter section 021 so that the space size enclosed by the inner offset section 023 and the lower shell 03 is smaller than the space size enclosed by the same-diameter section 021 and the lower shell 03, and the control key 2 is arranged in the transition section 022 and / or the inner offset section 023.

[0055] In this embodiment, the inner offset section 023 and the same diameter section 021 are offset from each other, which provides an installation space for the control key 2 while ensuring that the overall radial size of the handle remains basically unchanged; the setting of the transition section 022 not only allows the airflow to flow smoothly, but also increases the flow rate of the airflow.

[0056] refer to Figure 1 , Figure 4 , Figure 5 In one embodiment, a wiring groove 8 is provided on the outer side of the second upper shell 02, and a clearance notch 9 is provided on the first upper shell 01. The wiring groove 8 and the clearance notch 9 are used to lay out the wires between the PCB circuit board 3 and the control key 2. It can be understood that, compared with wiring inside the housing 1, arranging the wires between the PCB circuit board 3 and the control key 2 in the wiring groove 8 on the outer side of the second upper shell 02 can improve the convenience of wiring on the one hand, and can reduce the influence of the wires on the airflow and reduce the airflow noise on the other hand.

[0057] refer to Figure 1 , Figure 4 , Figure 5 In one embodiment, a first connecting ear 10 is provided at one end of the first upper shell 01 close to the second upper shell 02, and a second connecting ear 11 is provided at one end of the second upper shell 02 close to the first upper shell 01.

[0058] It is worth noting that, through the design of overlapping the first connecting ear 10 and the second connecting ear 11, the first upper shell 01 and the second upper shell 02 can be fixed to the lower shell 03 with the same screw. Compared with fixing the first upper shell 01 and the second upper shell 02 to the lower shell 03 separately, the fixing procedure of fixing the first upper shell 01 and the second upper shell 02 to the lower shell 03 is saved, thereby improving the assembly efficiency of the outer shell 1.

[0059] refer to Figure 2 , Figure 3 , Figure 5 In one embodiment, the fan assembly 4 is provided with a vibration-damping sleeve 12. By providing the vibration-damping sleeve 12, the vibration-damping sleeve 12 can absorb the vibration energy generated when the fan assembly 4 is working, reduce the vibration energy transmitted to the housing 1, and play a role in reducing vibration noise and handle vibration. The vibration-damping sleeve 12 can be made of soft rubber, such as silicone, or made of sound-absorbing cotton.

[0060] refer to Figure 5 In one embodiment, a filter cover 13 is provided at the end of the handle, and the filter cover 13 covers the outside of the air inlet 5. By providing the filter cover 13, debris can be prevented from entering the air inlet 5, reducing the risk of damage to the PCB circuit board 3 and the fan assembly 4.

[0062] In this embodiment, the specific structure of the handle refers to the aforementioned embodiment. Since the hair dryer adopts the technical solution of the aforementioned embodiment, it at least has the beneficial effects brought by the technical solution of the aforementioned embodiment, which will not be described one by one here.
