Description

Technical Field

[0001] This invention relates to the field of hair styling tools, specifically to a hair styling tool, its air guide box, and a method for coating graphene inside the air guide box. Background Technology

[0002] A hair straightener, also known as an electric straightener, is a type of hair styling tool whose function, as the name suggests, is to straighten hair. It uses a heating element to heat and soften the hair, and then cools it to achieve the purpose of straightening. Similarly, by changing the technique used, straight hair can also be made curly to achieve the purpose of styling. As hair straighteners have entered the Chinese household market, they have gradually developed into an essential personal care product, as ubiquitous as combs.

[0003] Traditional hair straighteners heat the hair using ceramic, PTC, or MCH heating elements. However, these methods have a significant drawback: because they require direct contact with the hair, they can easily damage the hair during use, leading to dryness and split ends with prolonged use.

[0004] With the development of related fields, existing hair straighteners have begun to combine the technology of the original hair dryer. The hair straightener is equipped with a fan and a heating element. The airflow generated by the fan blows over the heating element to form hot air, which in turn heats the user's hair. This heating method is less damaging to the hair than the original direct contact. At the same time, because this type of hair straightener can blow out hot air, it can also be used as a hair dryer, making it more functional.

[0005] Existing hair straighteners with hot air functions, in addition to the fan and heating element that generates hot air, retain the original contact heating method for the hair, thus enabling these straighteners to have multiple uses. For example, Chinese patent number ZL202411510616.3 discloses: "A hair straightener, including a lower handle, inner barrel, heating element, motor, circuit board, cable protector, filter support, tail ring, upper handle, lower aluminum plate, handle cover, locking knob, upper cover plate, upper aluminum plate, fixing plate, lower cover plate, air outlet frame, and button circuit board. Compared with the prior art, this invention adds a hair dryer function to the basic hair straightener and can blow hot air at high speed, making the hair straightener and hair dryer two-in-one, which is more convenient to use."

[0006] However, including the solutions in the aforementioned patents, existing hair straighteners with hot air blowing functions all have a drawback. Since hair dryers are generally cylindrical with their nozzles at the ends, the hot air from a hair dryer is uniform. However, since hair straighteners are generally flat, the nozzles on their heads can only be made into straight strips. Furthermore, due to the limited space inside the hair straightener, the air intake and the blower motor need to be located inside the handle. This results in some of the airflow from the handle to the head being blown out of the nozzle before being fully heated by the heating element, while the remaining airflow is blown out of the nozzle only after being fully heated by the heating element. This causes the temperature of the hot air blown out at different temperatures, resulting in uneven hot air temperature from existing hair straighteners with hot air blowing functions. Summary of the Invention

[0007] In order to overcome the shortcomings of the existing straighteners with hot air blowing function, which produce uneven hot air temperature, the present invention provides a hair styling tool, its air guide box, and a method for coating graphene inside the air guide box.

[0008] The technical solution of this invention to solve its technical problem is: a hair styling tool, comprising:

[0009] The appliance body also includes an upper component and a lower component, both of which have a handle and a head, and the handles of the two are hinged together. The upper component and the lower component can rotate relative to each other so that their heads move closer or further apart.

[0010] An air supply mechanism is provided inside the lower component. The lower component is also provided with an air intake on its handle and an air blower on its head. The air supply mechanism includes an air supply motor located in the air duct between the air intake and the air blower. The air supply mechanism also includes a first heating device located between the air supply motor and the air blower.

[0011] The air supply mechanism also includes a transition air cavity, which includes an air inlet and an air outlet, wherein the air inlet is connected to the air supply motor and the air outlet is connected to the air blower.

[0012] The transition air cavity is also provided with a partition plate, which divides the transition air cavity into a front chamber and a rear chamber. The air inlet is opened on one side of the front chamber, and the air outlet is opened on one side of the rear chamber. There is also a connecting window between the front chamber and the rear chamber.

[0013] The air inlet is located at one end of the front chamber, while the connecting window is located at the other end of the front chamber, so that the airflow entering the transition air chamber through the air inlet needs to pass through the front chamber before entering the rear chamber, and finally be discharged through the air outlet.

[0014] The first heating device is located in the front chamber.

[0015] Furthermore, the partition plate is arranged longitudinally so that the rear chamber and the front air chamber are distributed laterally on the left and right sides of the partition plate. One end of the partition plate in the longitudinal direction is connected to the cavity wall of the transition air chamber, and the other end of the partition plate in the longitudinal direction leaves a gap with the cavity wall of the transition air chamber to form a connecting window.

[0016] Furthermore, the partition plate includes a longitudinal partition section and a transverse connecting section. The partition section is located between the front air chamber and the rear chamber of the transition air chamber. The connecting section extends toward the rear chamber side of the transition air chamber and connects with the cavity wall at the rear chamber. The connecting section is located below the air outlet in the longitudinal direction. There is also a guide section between the partition section and the connecting section. A guide arc surface is provided on the side of the guide section near the rear chamber. The guide arc surface is aligned with the air outlet so that the airflow in the rear chamber can flow toward the air outlet under the guidance of the guide arc surface.

[0017] Furthermore, a diffusion air cavity is provided between the transition air cavity and the air outlet. The transition air cavity is connected to the diffusion air cavity through the air outlet opening. The air outlet is configured as a plurality of air holes opened at the bottom of the diffusion air cavity. The air holes are arranged in a straight line along the longitudinal direction. The air outlet opening is located at the middle position in the longitudinal direction of the diffusion air cavity, so that after the airflow enters the diffusion air cavity through the air outlet opening, it diffuses to both sides along the longitudinal direction of the diffusion air cavity.

[0018] Furthermore, the air supply mechanism includes an air guide box detachably connected to the lower component. The transition air cavity and the diffusion air cavity are both opened inside the air guide box. The air outlet is opened on one side of the air guide box. An exposure window is opened on the inner side of the head of the lower component. The side of the air guide box with the air outlet is exposed to the inner side of the head of the lower component through the exposure window. The air guide box includes a detachably connected lower box body and an upper cover body. Both the lower box body and the upper cover body are provided with a number of claws and buckles. The lower box body and the upper cover body are connected by the engagement of the buckles and claws.

[0019] Furthermore, an air guide duct is also fitted around the blower motor. The air guide duct is open at both ends, with one end facing the air intake. The other end of the air guide duct is connected to the air guide box, so that the opening at that end of the air guide duct communicates with the air inlet on the air guide box.

[0020] Furthermore, the air supply mechanism also includes a temperature sensor located within the transition air cavity. The temperature sensor is located at the air outlet, and an electronic control component is also provided within the lower component. The electronic control component includes an electronic control board and several control buttons. The air supply motor, the first heating device, and the temperature sensor are all connected to the electronic control board. One of the control buttons is a smart control button, and the electronic control board integrates a smart control element. Pressing the smart control button can activate and deactivate the smart control element. The smart control element can control the electronic control board to activate the smart control mode. In the smart control mode, the air supply motor can automatically start and stop and automatically change its wind speed under the control of the electronic control board. The electronic control board can also control the first heating device to automatically start and stop and automatically change its heating power based on the temperature information fed back by the temperature sensor.

[0021] Furthermore, a second heating device is also connected to the inner side of the head of the lower component.

[0022] The present invention also includes an air guide box suitable for the above-mentioned hair styling tool, wherein the inner wall of the air guide box is coated with a graphene coating.

[0023] The present invention also includes a method for coating the inner wall of an air guide box with graphene, applicable to the aforementioned air guide box, comprising the following steps:

[0024] S1. Cleaning: Thoroughly clean the lower box and upper cover of the air guide box using ultrasonic cleaning equipment;

[0025] S2. Sandblasting: The inner walls of the lower box and the upper cover are sandblasted using sandblasting equipment to improve their surface roughness;

[0026] S3. Spraying: Install the lower box and the upper cover onto the spraying mold, and spray the graphene coating onto the inner walls of the lower box and the upper cover through the nozzle on the spraying mold;

[0027] S4. Drying: Dry at room temperature for 10-20 minutes;

[0028] S5. Curing: Place the dried lower box and upper cover into a UV device and irradiate with UV light for 2-5 minutes to cure.

[0029] In step S3, the spraying mold includes a mold body with a spraying platform protruding from its surface. Several nozzles are densely arranged on the spraying platform, and a ring of interlocking grooves is formed around the spraying platform on the surface of the mold body. The edges of the lower box and the upper cover can be engaged with the interlocking grooves so that the spraying platform can be fitted to the inner side of the lower box and the upper cover, thereby aligning the nozzles on the spraying platform with the inner walls of the lower box and the upper cover.

[0030] The method of using and operating process of the hair styling tool of the present invention:

[0031] When this hairstyling tool requires hot air to dry or style hair, the upper and lower components can be flipped to separate their heads. After placing the hair between the heads of the upper and lower components, they can be flipped back together. Then, pressing the control button activates the blower motor and the second heating element. The blower motor draws air in through the air inlet on the lower component and, after creating an airflow, directs it towards the head of the upper component. Because the blower motor is encased in an air guide tube, the airflow is drawn in from one end of the air guide tube and then delivered to the air inlet of the air guide box from the other end. After entering the air guide box, the airflow first passes through the front chamber of the transition air cavity and then through the connecting... The window bypasses the partition and enters the rear chamber. Since the airflow from the air inlet to the connecting window needs to pass through the entire front chamber, and the first heating device is also located in the front chamber, the airflow entering the rear chamber through the connecting window has already been heated. Then, the hot airflow in the rear chamber will converge towards the air outlet under the guidance of the air guide arc surface, and finally the hot airflow will enter the diffuser cavity through the air outlet. The hot airflow entering the diffuser cavity will diffuse along the longitudinal direction to both sides and be blown out through the blower hole on one side of the diffuser cavity, so that hot air can be formed at the blower of the upper component head, thereby drying or styling the hair located between the upper and lower components.

[0032] When this hairstyling tool needs to style hair by direct heating, it is also necessary to first separate the upper and lower components by flipping them relative to each other, place the hair between the two components, and then flip the upper and lower components together. Then, the second heating device can be activated by pressing the control button, so that the second heating device can heat and style the hair that is in direct contact with it.

[0033] The beneficial effects of this invention are as follows:

[0034] 1. A transition air chamber is added to the air supply mechanism of the hair styling tool, and it is divided into a front chamber and a rear chamber by a partition plate. This ensures that the airflow flowing through the transition air chamber can be fully heated by the first heating device in the front chamber, thereby ensuring that the hot air blown out from the transition air chamber is fully heated and avoiding the problem of uneven temperature of the blown hot air.

[0035] 2. A diffusion air chamber is also provided after the transition air chamber. The air outlet connecting the transition air chamber and the diffusion air chamber is opened in the middle of the longitudinal direction of the diffusion air chamber. This ensures that the hot air entering the transition air wall can be evenly diffused into the entire diffusion air chamber. When the hot air is discharged from the blow holes on the side of the diffusion air chamber, it ensures that the air volume at each blow hole is relatively uniform, so that the air volume of the hot air blown out by this hair styling device is also more uniform.

[0036] 3. Equipped with a smart control button and smart control components, the smart control mode of this hair styling tool can be activated with one click. In this mode, the user does not need to perform any further operations. The control board can automatically adjust the blower motor and the first heating device according to information such as usage time and temperature, and can only complete the drying or styling of the hair, making this hair styling tool more intelligent and simplifying the operation for the user.

[0037] 4. The inner wall of the air guide box is coated with a graphene coating, which makes the first heating device in the air guide box more efficient in heating the airflow and more uniform in heating the airflow, further ensuring the uniformity of the hot air blown out by this hair styling tool.

[0038] 5. A method for coating graphene inside the air guide box is also provided, which can ensure uniform graphene coating on the inner wall of the air guide box by relying on its process and special spraying mold. Attached Figure Description

The blower mechanism includes a blower motor 7 located in an air duct between the air intake 5 and the air blower 6, and a first heating device 8 located between the blower motor 7 and the air blower 6. The blower mechanism also includes a transition air chamber 9, which includes an air inlet 10 and an air outlet 11, wherein... The air inlet 10 is connected to the blower motor 7, and the air outlet 11 is connected to the blower 6. A partition plate 12 is also provided in the transition air cavity 9, which divides the transition air cavity 9 into a front chamber 13 and a rear chamber 14. The air inlet 10 is opened on one side of the front chamber 13, and the air outlet 11 is opened on one side of the rear chamber 14.

The first heating device 8 is disposed in the front chamber 13.

[0055] Combination Figure 3 , Figure 6 and Figure 7 As shown, in this embodiment, the partition plate 12 is arranged longitudinally so that the rear chamber 14 and the front air chamber are distributed laterally on the left and right sides of the partition plate 12. One end of the partition plate 12 in the longitudinal direction is connected to the cavity wall of the transition air chamber 9, and the other end of the partition plate 12 in the longitudinal direction is left with a gap between it and the cavity wall of the transition air chamber 9 to form a connecting window 15.

[0056] Combination Figure 3 and Figure 6As shown, in this embodiment, the partition plate 12 includes a longitudinal partition section 16 and a transverse connecting section 17. The partition section 16 is located between the front air chamber and the rear chamber 14 of the transition air chamber 9.

A guide arc surface 19 is provided on the side of the guide section 18 near the rear chamber 14. The guide arc surface 19 is aligned with the air outlet 11 so that the airflow in the rear chamber 14 can flow toward the air outlet 11 under the guidance of the guide arc surface 19.

[0057] Combination Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, a diffusion air cavity 20 is also provided between the transition air cavity 9 and the air outlet 6. The transition air cavity 9 is connected to the diffusion air cavity 20 through the air outlet 11. The air outlet 6 is configured as a plurality of air holes 21 opened at the bottom of the diffusion air cavity 20. The air holes 21 are arranged in a straight line along the longitudinal direction. The air outlet 11 is located at the middle position in the longitudinal direction of the diffusion air cavity 20, so that after the airflow enters the diffusion air cavity 20 through the air outlet 11, it diffuses to both sides along the longitudinal direction of the diffusion air cavity 20.

[0058] Combination Figure 2 and Figures 5 to 8 As shown, the air supply mechanism in this embodiment includes an air guide box 22 detachably connected to the lower component 2. The transition air cavity 9 and the diffusion air cavity 20 are both opened in the air guide box 22. The air outlet 6 is opened on one side of the air guide box 22. An exposure window 23 is opened on the inner side of the head 4 of the lower component 2. The side of the air guide box 22 with the air outlet 6 is exposed to the inner side of the head 4 of the lower component 2 through the exposure window 23. The air guide box 22 includes a detachably connected lower box body 24 and an upper cover body 25. The lower box body 24 and the upper cover body 25 are each provided with a plurality of claws 26 and buckles 27. The lower box body 24 and the upper cover body 25 are connected by the snap-fit ​​of the buckles 27 and the claws 26.

[0059] Among them, such as Figure 9 As shown in the figure, in this embodiment, a guide tube 28 is also sleeved outside the blower motor 7. The guide tube 28 has openings at both ends, and one end of the guide tube 28 is set towards the air intake 5. The other end of the guide tube 28 is connected to the air guide box 22, so that the opening at that end of the guide tube 28 is connected to the air inlet opening 10 on the air guide box 22.

[0060] Combination Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, in this embodiment, the air supply mechanism also includes a temperature sensor 29 located in the transition air cavity 9. The temperature sensor 29 is located at the air outlet 11, and an electronic control component is also provided in the lower component 2. The electronic control component includes an electronic control board 30 and several control buttons 31. The air supply motor 7, the first heating device 8, and the temperature sensor 29 are all connected to the electronic control board 30. The control buttons 31 include a smart control button 32. The electronic control board 30 integrates a smart control element 33. Pressing the smart control button 32 can drive the smart control element 33 to open and close. The smart control element 33 can control the electronic control board 30 to start the smart control mode. In the smart control mode, the air supply motor 7 can automatically start and stop and automatically change the wind speed under the control of the electronic control board 30. The electronic control board 30 can also control the first heating device 8 to automatically start and stop and automatically change the heating power based on the temperature information fed back by the temperature sensor 29.

[0061] Combination Figures 2 to 4 As shown, in this embodiment, a second heating device 34 is also connected to the inner side of the head 4 of the lower component 2.

[0062] The usage method and operation process of this embodiment are as follows:

[0063] When this hairstyling tool requires hot air to dry or style hair, the upper component 1 and lower component 2 can be flipped to separate their heads 4. After placing the hair between the heads 4 of the upper component 1 and lower component 2, the two components can be flipped back together. Then, the blower motor 7 and the second heating device 34 can be activated by pressing the control button 31. The blower motor 7 draws air in from the air intake 5 on the lower component 2 and, after forming an airflow, delivers the airflow to the head 4 of the upper component 1. Since the blower motor 7 is covered by an air guide tube 28, the airflow is drawn in from one end of the air guide tube 28 and then delivered to the air inlet 10 of the air guide box 22 from the other end. After entering the air guide box 22, the airflow first passes through the front chamber 13 of the transition air chamber 9 and then bypasses through the connecting window 15. The partition plate 12 enters the rear chamber 14. Since the airflow from the air inlet 10 to the connecting window 15 needs to pass through the entire front chamber 13, and the first heating device 8 is also located in the front chamber 13, the airflow entering the rear chamber 14 through the connecting window 15 has been heated. Then, the hot airflow in the rear chamber 14 will be guided by the air guide arc surface 19 and converge towards the air outlet 11. Finally, the hot airflow enters the diffuser 20 through the air outlet 11. The hot airflow entering the diffuser 20 is diffused along the longitudinal direction to both sides and blown out through the blower hole 21 on one side of the diffuser 20, so that hot air can be formed at the blower 6 of the head 4 of the upper component 1, thereby drying or styling the hair located between the head 4 of the upper component 1 and the lower component 2.

[0064] When this hairstyling tool needs to style hair by direct heating, it is also necessary to first separate the heads 4 of the upper component 1 and the lower component 2 by flipping them relative to each other. After placing the hair between the heads 4, the upper component 1 and the lower component 2 are flipped together. Then, the second heating device 34 can be activated by pressing the control button 31, so that the second heating device 34 can heat and style the hair that is in direct contact with it.

[0065] The advantage of this embodiment is that a transition air cavity is added to the air supply mechanism and the transition air cavity is divided into two chambers, front and rear. The first heating device is placed in the front chamber, so that the airflow entering the rear chamber must completely pass through the first heating device, thereby ensuring that the hot air blown out from the rear chamber is uniform.

[0066] Example 2

[0067] This embodiment is a further refinement of the air guide box structure in Embodiment 1 above. The main distinguishing feature of this embodiment is:

[0068] In this embodiment, the inner wall of the air guide box 22 is coated with a graphene coating.

[0069] The remaining structures and methods in this embodiment are consistent with those in Embodiment 1 above, and will not be repeated here.

[0070] The advantage of this embodiment is that the coating structure on the inner wall of the air guide box has been further refined. Relying on the graphene coating on its inner wall, the first heating device can heat the airflow more quickly and evenly.

[0071] Example 3

[0072] This embodiment is a further explanation of the graphene coating method inside the air guide box in Embodiment 2 above. The main difference in this embodiment is as follows:

[0073] The coating method described in this embodiment includes the following steps:

[0074] S1. Cleaning: Thoroughly clean the lower box 24 and upper cover 25 of the air guide box 22 using ultrasonic cleaning equipment.

[0075] S2. Sandblasting: The inner walls of the lower box 24 and the upper cover 25 are sandblasted using sandblasting equipment to improve their surface roughness.

[0076] S3. Spraying: Install the lower box 24 and the upper cover 25 onto the spraying mold, and spray the graphene coating onto the inner walls of the lower box 24 and the upper cover 25 through the nozzle 42 on the spraying mold.

[0077] S4. Drying: Dry at room temperature for 10-20 minutes;

[0078] S5. Curing: Place the dried lower box body 24 and upper cover body 25 into a UV device and irradiate with UV light for 2-5 minutes to cure.

[0079] Combination Figure 11 As shown, the spraying mold used in step S3 of this embodiment includes a mold body 40. A spraying platform 41 is raised on the surface of the mold body 40. A plurality of nozzles 42 are arranged densely on the spraying platform 41. A ring of fitting grooves 43 is also formed on the surface of the mold body 40 around the spraying platform 41. The edges of the lower box 24 and the upper cover 25 can be engaged and fitted into the fitting grooves 43, so that the spraying platform 41 can fit into the inner side of the lower box 24 and the upper cover 25, thereby aligning the nozzles 42 on the spraying platform 41 with the inner walls of the lower box 24 and the upper cover 25.

[0080] The remaining structures and methods in this embodiment are consistent with those in Embodiment 1 above, and will not be repeated here.

[0081] The advantage of this embodiment is that by using the method and mold in this embodiment to spray graphene coating on the inner wall of the air guide box, the graphene distribution on the inner wall can be more uniform.

[0082] Example 4

[0083] Combination Figure 9 As shown, this embodiment is a further refinement of the air guide structure in Embodiment 1 above. The main distinguishing feature of this embodiment is:

[0084] In this embodiment, the surface of the air guide duct 28 is also connected to a wire clamping component 35. The wire clamping component 35 has several wire clamping grooves 36. The wires inside the lower component 2 can be clamped into the wire clamping grooves 36, which facilitates the arrangement of the wires inside the lower component 2 during assembly. In addition, the wire clamping component 35 is made of soft material and abuts against the inner wall of the lower component 2, thereby mitigating the vibration generated when the blower motor 7 starts and reducing the noise generated when the blower motor 7 runs.

[0085] The remaining structures and methods in this embodiment are consistent with those in Embodiment 1 above, and will not be repeated here.

[0086] The advantage of this embodiment is that, based on the above embodiment one, the sharp line structure and noise reduction structure inside the lower component have been further refined.

[0087] Example 5

[0088] Combination Figure 10 As shown, this embodiment is a further refinement of the electronic control component structure in Embodiment 1 above. The main distinguishing feature of this embodiment is:
