Description

Technical Field

[0001] This utility model relates to the field of hair styling tools, specifically to a curling iron attachment and a hair dryer. Background Technology

[0002] In the hair styling process, hair dryers are commonly used tools, and there are many different types. Among them, in addition to the most common hair dryer, the most common one is the curling iron. The main body of the curling iron is shaped like a rod or a cylinder. During use, the main body rotates, causing the hair wrapped around it to curl.

[0003] Traditional curling irons work by directly heating the hair to help it bend, which can damage the hair due to the high temperature. As a result, curling irons that use airflow to curl the hair have appeared on the market. These curling irons generally have a main body that blows air and a detachable curling iron attachment that is attached to the main body. The curling iron attachment has air ducts inside to create an airflow around it.

[0004] For example, Chinese patent number ZL 202421912173.6 discloses: "A hair curling accessory and a hair curling device, the hair curling accessory including an inner component and multiple arc-shaped guide plates, the inner component having an air inlet, an air guide cavity and an air outlet groove connected in sequence, the multiple air outlet grooves being distributed at intervals on the side wall of the inner component, the airflow output by the blower sequentially passing through the air inlet, the air guide cavity and the air outlet groove and exiting the air guide cavity; the arc-shaped guide plates are covered on the periphery of the inner component, and the arc-shaped guide plates are provided with a connection at the air outlet grooves." The air outlet connects to the air passage and the air outlet. The airflow is discharged from the air outlet to the surface of the hair curling accessory. Due to the curvature of the surface of the arc-shaped guide plate, the airflow discharged from the air outlet undergoes the Coanda effect and flows along the surface of the arc-shaped guide plate, thereby causing the hair to automatically adhere to the surface of the arc-shaped guide plate. The arc-shaped guide plate is directly fastened to the surface of the internal component, which simplifies the product assembly and prevents the air outlet from being affected by the assembly differences between the arc-shaped guide plate and the internal component, thereby improving the assembly yield and reducing the defect rate.

[0005] However, including the solutions in the aforementioned patents, all existing hair dryers and curling irons have a problem: the single air outlet restricts the direction of airflow around the curling iron, causing these curling irons to only curl hair in one direction, resulting in fewer styles that users can achieve.

[0006] With the development of technology, curling irons that can achieve bidirectional airflow have appeared on the market. However, these curling irons have relatively complex structures to achieve the change of airflow direction and cannot achieve quick and easy reversal. Summary of the Invention

[0007] In order to overcome the shortcomings of existing curling irons with bidirectional air outlet function, such as complex air structure and difficulty in reversing operation, this utility model provides a curling iron accessory and a hair dryer.

[0008] The technical solution of this utility model to solve its technical problem is: a curling iron accessory, which can be assembled onto the main body of a hair dryer, including:

[0009] The rotating cylinder has several air outlet areas on its circumference. Each air outlet area consists of a left air outlet and a right air outlet, both of which are opened along the axial direction of the rotating cylinder. The rotating cylinder also has several dividing ribs arranged around its circumference, which divide the inner cavity of the rotating cylinder into several mutually isolated air chambers. The air chambers are divided into a first air chamber that communicates with the left air outlet and a second air chamber that communicates with the right air outlet. The first and second air chambers are distributed circumferentially and alternately within the rotating cylinder.

[0010] A connecting seat is used to connect with the main body of the hair dryer, and the connecting seat is connected to the lower end of the rotating cylinder, which can rotate relative to the connecting seat; an air inlet is provided at the bottom of the connecting seat, and the air inlet is connected to the inner cavity of the rotating cylinder; several wind baffles are also provided in the connecting seat above the air inlet, and the wind baffles are arranged around the circumference of the connecting seat, with ventilation gaps between adjacent wind baffles;

[0011] The wind baffle can be aligned with one of the first and second air cavities to isolate the air cavity from the air inlet; the ventilation gap can be aligned with the other air cavity to establish communication between the air cavity and the air inlet.

[0012] Furthermore, the rotating cylinder can change its position relative to the connecting seat by rotating, and the rotating cylinder has at least a first position state and a second position state.

[0013] When the rotating cylinder rotates to the first position, the wind baffle in the connecting seat is aligned with the first air chamber in the rotating cylinder. The first air chamber is separated from the air inlet by the wind baffle, while the ventilation gap in the connecting seat is aligned with the second air chamber. The second air chamber is connected to the air inlet through the ventilation gap.

[0014] When the rotating cylinder rotates to the second position, the wind baffle in the connecting seat is aligned with the second air chamber in the rotating cylinder. The second air chamber is separated from the air inlet by the wind baffle, while the ventilation gap in the connecting seat is aligned with the first air chamber. The first air chamber is connected to the air inlet through the ventilation gap.

[0015] Furthermore, a limiting groove is provided at the lower end of the rotating cylinder, and a limiting block is protruding on the connecting seat. The limiting block is engaged with the limiting groove. When the rotating cylinder rotates relative to the connecting seat, the limiting block can also reciprocate within the limiting groove, and the left or right wall of the limiting groove can abut against the limiting block to prevent the limiting block from continuing to move to the left or right, thereby limiting the rotation angle of the rotating cylinder relative to the connecting seat.

[0016] Furthermore, the connecting seat is provided with a mounting hole, in which a gear spring and a gear bolt are inserted. The head of the gear bolt extends out of the mounting hole under the action of the gear spring. The rotating cylinder is provided with a first gear groove and a second gear groove. The head of the gear bolt can be engaged with the first gear groove and the second gear groove. As the rotating cylinder rotates relative to the connecting seat, the gear bolt can move and switch between the first gear groove and the second gear groove.

[0017] Furthermore, each of the windbreak ribs has two air guide slopes on its lower side, one of which is inclined toward the ventilation gap on the left side of the windbreak rib, and the other is inclined toward the ventilation gap on the right side of the windbreak rib.

[0018] Furthermore, several air guide plates are connected to the periphery of the rotating cylinder. Each air guide plate is correspondingly set at an air outlet area. The air guide plate blocks the front of the left and right air outlets. There are air outlet gaps between the air guide plate and the left and right air outlets. The airflow at the left and right air outlets needs to be blown out through the air outlet gaps.

[0019] Furthermore, several assembly grooves are provided on the periphery of the rotating cylinder, and assembly ribs are protruding on the air guide plate. The assembly ribs are inserted into the assembly grooves, and fixing holes are provided at the bottom of the assembly grooves. Fixing buckles are protruding on the assembly ribs and are snapped into the fixing holes to realize the connection between the air guide plate and the rotating cylinder.

[0020] Furthermore, the rotating cylinder is formed by connecting an outer shell and an inner support. The left and right air outlets are located on the outer shell, while the partition ribs are located on the inner support. The inner wall of the outer shell is provided with several insertion slots, and the partition ribs can be inserted into the insertion slots to realize the transmission connection between the outer shell and the inner support.

[0021] Furthermore, an operating button is also connected to the top of the outer shell. A snap-fit ​​groove is provided on the top of the outer shell, and a snap-fit ​​claw protrudes from the bottom of the operating button. The snap-fit ​​claw can engage with the snap-fit ​​groove to achieve a transmission connection between the operating button and the outer shell.

[0022] This utility model also includes a hair dryer, which includes a handheld component and a curling iron attachment as described above;

[0023] The curling iron accessory is mounted on the handheld component;

[0024] The handheld assembly includes a handheld housing, a main control circuit board, a blower motor, and a control switch; the handheld housing has an air supply cavity, the blower motor is located inside the air supply cavity, and the air supply cavity is connected to the inner cavity of the rotating cylinder; the control switch is exposed on the surface of the handheld housing and is connected to the main control circuit board; the main control circuit board can be electrically connected to an external power source via a power cord.

[0025] The usage and reversing method of this utility model:

[0026] Before use, the curling iron attachment needs to be installed on the handheld component. After connecting the power cord to the external power source, turn on the blower motor by operating the control switch on the handheld component. This creates an upward airflow in the air delivery chamber. The airflow enters the first or second air chamber through the air inlet and ventilation gap on the connector. Then, the airflow is discharged from the left or right air outlet. Because the airflow is blocked by the air guide plate, it can only be blown out through the air outlet gap on one side of the air guide plate. The airflow blown out from the air outlet gap adheres closely to the outer surface of the rotating barrel. Multiple airflows blown out from the rotating barrel will converge to form a ring-shaped airflow around the rotating barrel. At this time, the user wraps their hair around the outer surface of the rotating barrel, and the hair will rotate and curl under the action of the ring-shaped airflow.

[0027] When it is necessary to change the direction of the annular airflow, simply grasp and turn the operating button at the top of the cylinder to make the rotating cylinder rotate relative to the connecting seat. This changes the alignment of the first and second air chambers with the wind deflector on the connecting seat, thus changing the airflow from the left air outlet to the right air outlet, or vice versa. Since the left and right air outlets face opposite directions, the direction of the annular airflow generated on the surface of the rotating cylinder will change.

[0028] The beneficial effects of this utility model are as follows:

[0029] 1. The air outlet area is divided into a left air outlet and a right air outlet. The rotating barrel is equipped with a first air chamber and a second air chamber to connect with the two air outlets. The air baffle on the connecting seat blocks one of the air chambers, so that the airflow can be blown out from the left air outlet or the right air outlet. This allows the curling iron accessory to form two ring airflows with opposite directions, which can meet the different styling needs of users. At the same time, the structure for changing direction is relatively simple, and the operation of rotating the barrel is also very convenient.

[0030] 2. A limit structure and a gear structure are also provided between the rotating cylinder and the connecting seat to limit the rotation range of the rotating cylinder and to remind the rotating cylinder to switch gears, which further simplifies the reversing operation.

[0031] 3. A guide plate is also connected to the surface of the rotating cylinder. The guide plate can not only enhance the airflow velocity generated on the surface of the rotating cylinder, but also restrict the direction of the airflow, so that the airflows can smoothly converge to form a ring airflow.

[0032] 4. The curling iron is attached to the main body of the hair dryer as a separate accessory, allowing the curling iron accessory to be detached and replaced with other functional accessories, thereby increasing the product's versatility. Attached Figure Description

[0047] 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.

[0048] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0049] Example 1

[0050] Reference Figures 1 to 11As shown, a curling iron accessory, which can be assembled onto the main body of a hair dryer, includes a rotating cylinder 1 and a connecting seat 8. The rotating cylinder 1 has several air outlet areas 2 arranged around its periphery. Each air outlet area 2 consists of a left air outlet 3 and a right air outlet 4, both of which are located along the axial direction of the rotating cylinder 1. The rotating cylinder 1 also has several dividing ribs 5 arranged circumferentially inside, dividing the inner cavity of the rotating cylinder 1 into several mutually isolated air chambers. These air chambers are divided into a first air chamber 6 communicating with the left air outlet 3 and a second air chamber 7 communicating with the right air outlet 4. The first air chamber 6 and the second air chamber 7 are spaced apart circumferentially within the rotating cylinder 1. The connecting seat 8 is used to connect to the main body of the hair dryer. A connection is formed, and the connecting seat 8 is connected to the lower end of the rotating cylinder 1, which can rotate relative to the connecting seat 8. An air inlet 9 is provided at the bottom of the connecting seat 8, and the air inlet 9 is connected to the inner cavity of the rotating cylinder 1. Several wind-blocking ribs 10 are also provided above the air inlet 9 in the connecting seat 8. The wind-blocking ribs 10 are arranged around the circumference of the connecting seat 8, and a ventilation gap 11 is left between two adjacent wind-blocking ribs 10. The wind-blocking ribs 10 can be aligned with one of the first air chambers 6 and the second air chamber 7 to isolate the communication between the air chamber and the air inlet 9. The ventilation gap 11 can be aligned with the other air chamber of the first air chamber 6 and the second air chamber 7 to make the air chamber communicate with the air inlet 9.

[0051] Among them, such as Figure 11 As shown in the figure, in this embodiment, the rotating cylinder 1 can change its position relative to the connecting seat 8 by rotation, and the rotating cylinder 1 has at least a first position state a and a second position state b. When the rotating cylinder 1 rotates to the first position state a, the wind baffle 10 in the connecting seat 8 is aligned with the first air cavity 6 in the rotating cylinder 1, and the first air cavity 6 is separated from the air inlet 9 by the wind baffle 10. The ventilation gap 11 in the connecting seat 8 is aligned with the second air cavity 7, and the second air cavity 7 is connected to the air inlet 9 through the ventilation gap 11. When the rotating cylinder 1 rotates to the second position state b, the wind baffle 10 in the connecting seat 8 is aligned with the second air cavity 7 in the rotating cylinder 1, and the second air cavity 7 is separated from the air inlet 9 by the wind baffle 10. The ventilation gap 11 in the connecting seat 8 is aligned with the first air cavity 6, and the first air cavity 6 is connected to the air inlet 9 through the ventilation gap 11.

[0052] It should be noted that, in this embodiment, when the rotating cylinder 1 is in the first position state a, after the airflow is blown out from the right air outlet 4 through the second air chamber 7, the multiple airflows on the surface of the rotating cylinder 1 converge to form an annular airflow that rotates counterclockwise; while when the rotating cylinder 1 is in the second position state b, after the airflow is blown out from the left air outlet 3 through the first air chamber 6, the multiple airflows on the surface of the rotating cylinder 1 converge to form an annular airflow that rotates clockwise.

[0053] Combination Figure 5 and Figure 6 As shown, in this embodiment, a limiting groove 12 is provided at the lower end of the rotating cylinder 1, and a limiting block 13 is protruding on the connecting seat 8. The limiting block 13 is engaged in the limiting groove 12. When the rotating cylinder 1 rotates relative to the connecting seat 8, the limiting block 13 can also reciprocate within the limiting groove 12, and the left or right side wall of the limiting groove 12 can abut against the limiting block 13 to prevent the limiting block 13 from continuing to move to the left or right, thereby limiting the rotation angle of the rotating cylinder 1 relative to the connecting seat 8.

[0054] Combination Figure 5 and Figure 6 As shown, in this embodiment, the connecting seat 8 is also provided with a mounting hole 14. A gear spring 15 and a gear bolt 16 are inserted into the mounting hole 14. The head of the gear bolt 16 extends out of the mounting hole 14 under the action of the gear spring 15. The rotating cylinder 1 is provided with a first gear groove 17 and a second gear groove 18. The head of the gear bolt 16 can be engaged with the first gear groove 17 and the second gear groove 18. As the rotating cylinder 1 rotates relative to the connecting seat 8, the gear bolt 16 can move and switch between the first gear groove 17 and the second gear groove 18.

[0055] It should be noted that, in this embodiment, when the head of the shift bolt 16 is engaged in the first shift groove 17, the rotating cylinder 1 is in a first position state a relative to the connecting seat 8; when the head of the shift bolt 16 is engaged in the second shift groove 18, the rotating cylinder 1 is in a second position state b relative to the connecting seat 8; and since the head of the shift bolt 16 is always pressed against the rotating cylinder 1 under the action of the shift spring 15, there will be obvious tactile and audible feedback when the shift bolt 16 is engaged in the first shift groove 17 and the second shift groove 18, to remind the user to rotate it into place.

[0056] Among them, such as Figure 7As shown in the figure, in this embodiment, each of the windbreak ribs 10 has two air guide slopes 19 on its lower side. One of the air guide slopes 19 is inclined toward the ventilation gap 11 on the left side of the windbreak rib 10, and the other air guide slope 19 is inclined toward the ventilation gap 11 on the right side of the windbreak rib 10.

[0057] Combination Figure 3 and Figure 8 As shown, in this embodiment, several air guide plates 20 are connected to the circumference of the rotating cylinder 1. Each air guide plate 20 is correspondingly set at an air outlet area 2. The air guide plate 20 blocks the front of the left air outlet 3 and the right air outlet 4. There is also an air outlet gap 21 between the air guide plate 20 and the left air outlet 3 and the right air outlet 4. The airflow at the left air outlet 3 and the right air outlet 4 needs to be blown out through the air outlet gap 21.

[0058] It should be noted that, due to the small width of the air outlet gap 21, the airflow velocity can be increased when the airflow is blown out from the air outlet gap 21, and the airflow can fit more closely to the outer surface of the rotating cylinder 1.

[0059] Combination Figure 8 and Figure 9 As shown, in this embodiment, a plurality of assembly grooves 22 are provided on the circumference of the rotating cylinder 1, and an assembly rib 23 is protruding on the air guide plate 20. The assembly rib 23 is inserted into the assembly groove 22. A fixing hole 24 is also provided at the bottom of the assembly groove 22. A fixing buckle 25 is protruding on the assembly rib 23. The fixing buckle 25 is snapped into the fixing hole 24 to realize the connection between the air guide plate 20 and the rotating cylinder 1.

[0060] Combination Figure 2 and Figure 3 As shown, in this embodiment, the rotating cylinder 1 is formed by connecting an outer shell 26 and an inner support 27. The left air outlet 3 and the right air outlet 4 are opened on the outer shell 26, and the partition rib 5 is set on the inner support 27. The inner wall of the outer shell 26 is provided with several insertion grooves 28. The partition rib 5 can be inserted into the insertion grooves 28 to realize the transmission connection between the outer shell 26 and the inner support 27.

[0061] Combination Figure 8 and Figure 10 As shown, in this embodiment, the top of the outer shell 26 is also connected to an operation button 29. The top of the outer shell 26 is provided with a snap-fit ​​groove 30, and the bottom of the operation button 29 is provided with a snap-fit ​​claw 31. The snap-fit ​​claw 31 can form a snap-fit ​​engagement with the snap-fit ​​groove 30 to realize the transmission connection between the operation button 29 and the outer shell 26.

[0062] The reversing method of this embodiment is as follows: When it is necessary to change the direction of the annular airflow, simply grasp and rotate the operating button 29 at the top of the cylinder 1, so that it drives the rotating cylinder 1 to rotate relative to the connecting seat 8, thereby changing the alignment relationship between the first air chamber 6 and the second air chamber 7 and the wind deflector 10 on the connecting seat 8. This causes the airflow blown from the left air outlet 3 to be blown from the right air outlet 4, or the airflow blown from the right air outlet 4 to be blown from the right air outlet 4. Since the left air outlet 3 and the right air outlet 4 face opposite directions, the direction of the annular airflow generated on the surface of the rotating cylinder 1 will change.

[0063] The advantages of this embodiment are: it has two air outlets in opposite directions, and two isolated air chambers are set in the rotating cylinder to connect with the two air outlets respectively. One air chamber is blocked by the wind baffle on the connecting seat, while the other air chamber is open. This allows the air to be blown out at the two air outlets in different directions, thereby realizing the function of reversing direction. It can not only meet the needs of various shapes, but also has a simple structure and is very convenient to reverse direction.

[0064] Example 2

[0065] Reference Figures 12 to 13 As shown, a hair dryer includes a handheld component and a curling iron attachment as described in Embodiment 1; the curling iron attachment is mounted on the handheld component; the handheld component includes a handheld housing 32, a main control circuit board 33, a blower motor 34, and a control switch 35; an air delivery chamber 36 is provided inside the handheld housing 32, the blower motor 34 is located inside the air delivery chamber 36, and the air delivery chamber 36 communicates with the inner cavity of the rotating cylinder 1; the control switch 35 is exposed on the surface of the handheld housing 32 and is connected to the main control circuit board 33; the main control circuit board 33 can be electrically connected to an external power source via a power cord 37.

[0066] The usage method of this embodiment is as follows: First, before use, the curling iron attachment needs to be installed on the handheld component. After connecting the power cord 37 to the external power source, the blower motor 34 is turned on by operating the control switch 35 on the handheld component, so that an upward airflow is formed in the air delivery chamber 36. The airflow enters the first air chamber 6 or the second air chamber 7 through the air inlet 9 and ventilation gap 11 on the connecting seat 8. Then the airflow is discharged from the left air outlet 3 or the right air outlet 4. The discharged airflow is blocked by the air guide plate 20 and can only be blown out through the air outlet gap 21 on one side of the air guide plate 20. The airflow blown from the air outlet gap 21 is close to the outer surface of the rotating barrel 1. The multiple airflows blown out from the rotating barrel 1 will converge to form a ring airflow around the rotating barrel 1. At this time, the user wraps the hair around the outer surface of the rotating barrel 1, and the hair will rotate and curl under the action of the ring airflow.

[0067] The advantage of this embodiment is that the curling iron can be detachably connected to the handheld component as an accessory. By changing the accessory, the hair dryer can perform other functions, thus realizing the diversification of the product's functions.

[0068] The remaining structures and methods of this embodiment are consistent with those of Embodiment 1 above, and will not be repeated here. The specific embodiments described above are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
