Description

Technical Field

[0001] This application relates to the field of hair care equipment, and in particular to an adjustable airflow comb. Background Technology

[0002] With the improvement of people's living standards, more and more hair styling products have appeared on the market, among which hot air combs are very popular among women. These combs consist of a motor, a heating element, and comb teeth with an air duct at the top. When the machine is working, the motor's fan blades rotate, blowing air in from the bottom air inlet. After passing through the motor, the air flows over the heating element, carrying away the heat generated by the element, and then out through the air duct at the top, exiting from the comb teeth's air outlet. Currently, most hot air combs on the market are quite tall, resulting in uneven airflow as the airflow travels along the length of the comb head, leading to a poor user experience. Utility Model Content

[0003] To address the aforementioned issues, this application provides an adjustable airflow comb. By incorporating a first air duct and a second air duct within the comb assembly, both air ducts are equipped with air outlet groups. The air outlet position and direction are adjusted according to the corresponding connection or staggering between different air outlet groups, thereby achieving different air outlet methods on the comb assembly. Furthermore, the first air duct is equipped with air guide ribs, which ensure that the air blown from the bottom of the comb assembly is evenly blown along the length of the comb assembly, preventing airflow from concentrating at the lower part of the comb assembly.

[0004] An adjustable airflow comb includes a comb assembly and a handle assembly. The comb assembly includes a housing, comb teeth, and an air duct structure. The air duct structure is disposed within the housing, and the comb teeth are disposed on one side of the housing. The handle assembly has an air inlet, and the comb assembly has an air outlet. Airflow enters the handle assembly from the air inlet, passes through the air duct structure, and exits from the air outlet. The air duct structure includes a first air duct and a second air duct. The first air duct is disposed within the second air duct. The first air duct has a first air outlet group and a second air outlet group, and the second air duct has a third air outlet group and a fourth air outlet group. The air duct structure has a first working position where the first and third air outlet groups are correspondingly connected and the second and fourth air outlet groups are staggered and blocked, and a second working position where the second and fourth air outlet groups are correspondingly connected and the first and third air outlet groups are staggered and blocked. The inner wall of the first air duct has guide ribs extending radially inward from the inner wall of the first air duct.

[0005] The advantage is that the first and second air ducts are equipped with multiple air outlet groups. By connecting or staggering the air outlet groups, the air outlet position and direction can be adjusted to achieve different air outlet methods on the comb assembly. The first air duct is equipped with air guide ribs. Some airflow is blocked by the air guide ribs and blown out from the first or second air outlet group on both sides of the air guide ribs. This ensures that airflow is blown out from the top, middle and bottom of the comb assembly, making the air outlet uniform and preventing the airflow from concentrating at the bottom of the comb assembly.

[0006] Preferably, there are multiple air guide ribs, which are arranged in a staggered manner along the axial direction of the first air duct.

[0007] The advantages are that the staggered air guide ribs allow airflow to be blown out evenly along the axis of the first air duct, further improving the uniformity of airflow along the length of the comb assembly. Furthermore, the staggered arrangement optimizes space utilization.

[0008] Preferably, the first air outlet group includes multiple rows of first sub-air outlets arranged along the length of the first air duct, the multiple rows of first sub-air outlets being spaced apart in the circumferential direction of the first air duct, and the air guide ribs being provided between the multiple rows of first sub-air outlets.

[0009] The advantage is that multiple rows of first sub-outlets are distributed at intervals around the circumference of the first air duct, which allows the airflow to be blown out evenly from the circumference of the first air duct.

[0010] Preferably, the air outlet includes a first air outlet that is perforated and evenly distributed on the surface of the outer casing, and a second air outlet that is strip-shaped and disposed on one or both sides of the comb teeth. In the first working position, the airflow is discharged from the first air outlet, and in the second working position, the airflow is discharged from the second air outlet.

[0011] The advantage is that different air outlet methods can be achieved by setting multiple working positions to meet different air outlet function requirements.

[0012] Preferably, the second air outlet group is distributed on both sides of the comb teeth, and the second air outlet group includes two rows of second sub-air outlets, with air guide ribs provided between the two rows of second sub-air outlets.

[0013] The advantage is that by setting a second air outlet group on both sides of the comb teeth, and setting air guide ribs at the second sub-air outlet, the second air outlet group on both sides of the comb teeth can achieve uniform air output.

[0014] Preferably, the comb assembly includes a rotating component, which is threadedly connected to the first air blower. Rotating the rotating component can drive the first air blower to rotate, thereby switching between the first working position and the second working position.

[0015] The advantage is that the rotating component is connected to the first air duct by a thread, which is convenient to assemble and has a simple structure. By rotating the rotating component, different working positions can be switched to achieve different air outlet modes.

[0016] The second air duct includes at least two arc-shaped baffles, namely a first baffle and a second baffle. The first baffle and the second baffle can move up and down along the length of the first air duct, respectively. The third air outlet group is disposed on the first baffle, and the fourth air outlet group is disposed on the second baffle.

[0017] The advantage is that the airflow direction can be changed by adjusting the misalignment of the second baffle.

[0018] Preferably, the second air duct further includes a third baffle, which is located between the first baffle and the second baffle. A fifth air outlet group is provided on the corresponding area of ​​the first air duct covered by the third baffle, and a sixth air outlet group is provided on the third baffle. The third baffle moves up and down along the length of the first air duct to achieve communication or blockage between the fifth air outlet group and the sixth air outlet group.

[0019] The advantage is that the airflow direction can be changed by adjusting the misalignment of the third baffle.

[0020] Preferably, the first air duct is provided with positioning posts, and there are multiple positioning posts. The first baffle, the third baffle, and the second baffle are respectively connected to different positioning posts.

[0021] The advantage is that by assembling the baffle with the first air duct through the positioning column, the baffle can move up and down, and the structure is simple.

[0022] Preferably, the comb assembly further includes a heating unit, which is disposed inside the first air duct.

[0023] The advantage is that the length of other components is not changed without altering the height of the air outlet, thus reducing the overall length of the unit. Attached Figure Description

[0036] like Figure 1-8 As shown, an adjustable airflow comb includes a comb assembly 1 and a handle assembly 2. The comb assembly 1 includes a housing 3, comb teeth 4, and an air duct structure 5. The air duct structure 5 is disposed inside the housing 3, and the comb teeth 4 are disposed on one side of the housing 1. The handle assembly 2 is provided with an air inlet 6, and the comb assembly 1 is provided with an air outlet 7. Airflow enters the handle assembly 2 from the air inlet 6, passes through the air duct structure 5, and is blown out from the air outlet 7. The air duct structure 5 includes a first air duct 501 and a second air duct 502. The first air duct 501 is disposed inside the second air duct 502, and the first air duct 501 is provided with... The system has a first air outlet group 801 and a second air outlet group 802. The second air duct 502 is provided with a third air outlet group 803 and a fourth air outlet group 804. The air duct structure 5 has a first working position in which the first air outlet group 801 and the third air outlet group 803 are correspondingly connected and the second air outlet group 802 and the fourth air outlet group 804 are staggered and blocked, and a second working position in which the second air outlet group 802 and the fourth air outlet group 804 are correspondingly connected and the first air outlet group 801 and the third air outlet group 803 are staggered and blocked. The inner wall of the first air duct 501 is provided with a guide rib 10, which is located between the first air outlet group 801 and the second air outlet group 802.

[0037] In the first working position, the airflow entering the air duct structure 5 is discharged from the first air outlet group 801 and the third air outlet group 803; in the second working position, the airflow entering the air duct structure 5 is discharged from the second air outlet group 802 and the fourth air outlet group 804. By providing multiple air outlet groups on the first air duct 501 and the second air duct 502, and by correspondingly connecting or blocking the air outlet groups, the airflow is discharged from different air outlet groups, thereby realizing the airflow being discharged from different positions on the comb assembly 1; the first air duct 501 is provided with air guide ribs 10. After the airflow enters the first air duct 501, it moves along its axis. When the airflow encounters the air guide ribs 10, it is blocked and changes its original direction of travel, moving to the air outlet groups on both sides, and is blown out from the first air outlet group 501 or the second air outlet group 502 on both sides of the air guide ribs 10, preventing the airflow from accumulating at the bottom of the comb assembly 1 and improving the uniformity of airflow along the length of the comb assembly 1.

[0038] The air outlet 7 includes a second air outlet 902 that is perforated and evenly distributed on the surface of the housing 3, and a first air outlet 901 that is strip-shaped and disposed on both sides of the comb teeth 4; in the first working position, the airflow is discharged from the second air outlet 902; in the second working position, the airflow is discharged from the first air outlet 901.

[0039] Furthermore, the air guide ribs 10 are plate-shaped and extend radially inward from the inner wall of the first air duct 501. After the airflow enters the first air duct 501, it changes its original direction (the length direction of the first air duct) under the action of the air guide ribs 10 and is discharged to the first air outlet group 801 or the second air outlet group 802 on both sides, thereby improving the uniformity of airflow along the length direction of the comb assembly 1.

[0040] like Figure 1 , 2 As shown, a plurality of air guide ribs 10 are provided on the inner wall of the first air duct 501, and the air guide ribs 10 are arranged in a staggered manner along the axial direction of the first air duct 501. The staggered air guide ribs 10 change the direction of airflow at different positions, further improving the uniformity of airflow along the length of the comb assembly 1.

[0041] Furthermore, the first air outlet group 801 includes multiple rows of first sub-air outlets 8011 arranged along the length of the first air duct 501. The multiple rows of first sub-air outlets 8011 are spaced apart in the circumferential direction of the first air duct 501. Guide ribs 10 are provided between the multiple rows of first sub-air outlets 8011. The guide ribs 10 can be provided between two adjacent rows, or between two or more rows of first sub-air outlets 8011.

[0042] The second air outlet group 802 is distributed on both sides of the comb teeth 4. The second air outlet group 802 includes two rows of second sub-air outlets 8022, and air guide ribs are provided between the two rows of second sub-air outlets 8022.

[0043] like Figure 3 As shown, the comb assembly 1 includes a rotating assembly 11, which is threadedly connected to the first air blower 501. Rotating the rotating assembly 11 can drive the first air blower 501 to rotate, thereby switching between the first working position and the second working position.

[0044] Furthermore, such as Figure 1-4 As described above, when the rotating component 11 rotates to the point where the first air outlet group 801 and the third air outlet group 803 are correspondingly connected, the second air outlet group 802 and the fourth air outlet group 804 are staggered, and the airflow passes through the first air outlet group 801 and the third air outlet group 803, and is blown out from the second air outlet 902; when the rotating component 11 rotates to the point where the second air outlet group 802 and the fourth air outlet group 804 are correspondingly connected, the first air outlet group 801 and the third air outlet group 803 are staggered, and the airflow passes through the second air outlet group 802 and the fourth air outlet group 804, and is blown out from the first air outlet 901. This configuration allows for different air outlet modes to be achieved through the rotating component 11.

[0045] Another embodiment of the second air duct 502, such as Figure 5-8 As shown, the second air duct 502 consists of three baffles, namely the first baffle 1201, the third baffle 1203, and the second baffle 1202. The first baffle 1201, the third baffle 1203, and the second baffle 1202 can move up and down along the length of the first air duct 501, respectively.

[0046] In this embodiment, the third air outlet group 803 is disposed on the first baffle 1201 and the fourth air outlet group 804 is disposed on the second baffle 1202.

[0047] Furthermore, the first air duct 501 is also provided with a fifth air outlet group 805, and the second air duct 502 is provided with a sixth air outlet group 806 that cooperates with the fifth air outlet group 805. More specifically, the sixth air outlet group 806 is set on the third baffle 1203. When the sixth air outlet group 806 and the fifth air outlet group 805 are connected, the airflow can be discharged from the sixth air outlet group 806.

[0048] Furthermore, in the initial position, the first air outlet group 801 is connected to the third air outlet group 803, the second air outlet group 802 is connected to the fourth air outlet group 804, and the fifth air outlet group 805 is connected to the sixth air outlet group 806. When it is necessary to control the air outlet position, the first air duct 501 remains fixed. When the first baffle 1201 and the second baffle 1202 move upward in the axial direction, the first air outlet group 801 and the third air outlet group 803 are staggered and blocked, the second air outlet group 802 and the fourth air outlet group 804 are staggered and blocked, and the fifth air outlet group 805 and the sixth air outlet group 806 are connected. The airflow is discharged from the sixth air outlet group 806, and the airflow discharged from the sixth air outlet group 806 is discharged from the first air outlet 901.

[0049] The comb assembly 1 is C-shaped, and the second air outlet 902 is evenly distributed in a perforated manner on the surface of the comb assembly 1. The surface passing through the central axis of the comb assembly 1 divides the C-shaped comb assembly 1 into two symmetrical upper and lower parts, namely the first part and the second part. In another example, the first air duct 501 is fixed, and the third baffle 1203 moves upward so that the fifth air outlet group 805 and the sixth air outlet group 806 are staggered and blocked. The first air outlet group 801 is connected to the third air outlet group 803, and the second air outlet group 802 is connected to the fourth air outlet group 804. The airflow is discharged from all the second air outlets 902 on the C-shaped surface. In another example, the first air duct 501 is fixed, the third baffle 1203 moves upward to offset and block the fifth air outlet group 805 and the sixth air outlet group 806, the first baffle 1201 moves upward to offset and block the first air outlet group 801 and the third air outlet group 803, the second air outlet group 802 and the fourth air outlet group 804 are connected, and the airflow is discharged from the second air outlet 902 of the first part of the C-shaped comb assembly 1. In yet another example, the first air duct 501 is fixed, the third baffle 1203 moves upward to offset and block the fifth air outlet group 805 and the sixth air outlet group 806, the second baffle 1202 moves upward to offset and block the second air outlet group 802 and the fourth air outlet group 804, the first air outlet group 801 and the third air outlet group 803 are connected, and the airflow is discharged from the second air outlet 902 of the second part of the C-shaped comb assembly 1.

[0050] Understandably, "moving upwards" in the aforementioned example can be "moving downwards".

[0051] Understandably, the second air duct 502 consists of two arc-shaped baffles, namely the first baffle 1201 and the second baffle 1203. The third air outlet group 8013 is set on the second baffle, and the fourth air outlet group is set on the first baffle. By controlling the movement of the first baffle and the second baffle respectively, air can be discharged from the first air outlet 901 and / or the second air outlet 902.

[0052] like Figure 5-8As shown, the first air duct 501 is provided with a positioning post 13, and the first baffle 1201, the third baffle 1203, and the second baffle 1202 are connected to the first air duct 501 through the positioning post 13. The third baffle 1203 and the second baffle 1202 are assembled with the first air duct 501 through the positioning post 13, which can realize the up and down movement of the baffles, and the air outlet group on them is misaligned with the air outlet group on the first air duct 501 to control the air outlet direction.

[0053] like Figure 1 , 3 The comb assembly 1 further includes a heating unit 14, which is disposed inside the first air duct 501. This arrangement allows for a reduction in the overall length of the machine without altering the length of other components, while maintaining the same height of the air outlet 7.

[0054] The present application has been described above with reference to preferred embodiments; however, these embodiments are merely exemplary and illustrative. Various substitutions and modifications can be made to the present application based on these embodiments, all of which fall within the protection scope of the present application.
