Description

A foldable handheld hair care device Technical Field

[0001] This invention relates to the field of hair styling appliances, and more particularly to a foldable handheld hair care device. Background Technology

[0002] Hair care devices include combs, hair dryers, hair styling tools, and scalp massagers. Combing is an essential part of daily hair care. Combing removes dandruff and dirt from the scalp and hair, and provides gentle stimulation to the scalp, promoting blood circulation and leaving hair soft and shiny. Combs and hair dryers are common household items. Combs are mainly used for combing hair, beards, or animal fur, while hair dryers are mainly used for drying hair or beards. After washing their hair, users usually need to use a comb and a hair dryer separately to comb and dry their hair. Using a comb and hair dryer separately is relatively cumbersome and inconvenient, and the comfort level is relatively low. Combs are an improvement on hair dryers. This hair care tool can comb and massage hair while drying it. Different hair dryer nozzles can be used to suit different hairstyles and user groups. Therefore, combs have gradually become an essential hair care product.

[0003] Existing hair dryers typically have the handle and nozzle aligned in a straight line, resulting in a rigid overall shape. When using them, users need to constantly swing their arms to dry and comb their hair, depending on the type of hairdryer and nozzle used. This often requires raising the arm, which is strenuous and inconvenient, reducing the user experience. Furthermore, they take up too much space when stored, causing storage problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a foldable handheld hair care device in light of the current state of the technology.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a foldable handheld hair care device, including a hair care device, which is divided into a handle, a connecting part and a hair dryer. The hair dryer is characterized in that: the hair dryer can rotate freely on the handle through the connecting part; when the hair care device is in the open state, the hair dryer and the handle axis are basically coincident, forming a straight line; when the hair care device is in the folded state, the hair dryer and the handle form an angle.

[0006] Preferably, the connecting part includes a fixed part connected to the handle and a rotating part connected to the blower, the rotating part being rotatably disposed on both sides of the fixed part; the rotating part and the fixed part are provided with limiting parts for limiting the rotation angle, and the rotating part and the fixed part are also provided with positioning parts for positioning, the rotating part rotating relative to the fixed part and being limited by the limiting parts, the rotating part rotating relative to the fixed part and being positioned by the positioning parts.

[0008] Preferably, the limiting part includes a limiting strip disposed on the rotating part and a rotating groove that cooperates with the limiting strip for limiting. The rotating groove is disposed on both sides of the fixed part, and the limiting strip is arranged along the inner wall of the rotating part with a raised arc. Both ends of the limiting strip are limiting ends.

[0009] Preferably, the rotating groove is provided with a limiting protrusion that cooperates with the limiting end for limiting.

[0010] Preferably, the positioning part includes positioning members fixedly disposed on both sides of the fixed part, the inner wall of the rotating part is provided with a plurality of positioning teeth for positioning, and the positioning members are provided with locking teeth that cooperate with the positioning teeth for positioning.

[0011] Preferably, the first rotating member and the second rotating member are respectively provided with a first protruding shaft and a second protruding shaft, and the first rotating member and the second rotating member are connected by inserting the first protruding shaft and the second protruding shaft on both sides of the fixing member.

[0012] Preferably, the arc length of the limiting strip is at least 1 / 5 to 1 / 4 of the total arc length of the outer edge of the rotating part.

Example

[0032] As shown in Figures 1 to 6, the present invention provides a foldable handheld hair care device, including a hair care device, which is divided into a handle 1, a connecting part, and a hair dryer 2. The hair dryer 2 can rotate freely on the handle 1 through the connecting part. Specifically, the angle between the hair dryer 2 and the handle 1 is in the range of 60° to 180°. When the hair care device is in the open state, the axes of the hair dryer 2 and the handle 1 are basically coincident, forming a straight line. When the hair care device is in the folded state, the hair dryer 2 and the handle 1 form an angle of about 90°.

[0033] The connecting part includes a fixed part 3 connected to the handle 1 and a rotating part 4 connected to the blower 2. The rotating part 4 is rotatably disposed on both sides of the fixed part 3. Specifically, the rotating part 4 and the fixed part 3 are provided with limiting parts for limiting the rotation angle, and the rotating part 4 and the fixed part 3 are also provided with positioning parts for positioning. The rotating part 4 rotates relative to the fixed part 3 and is limited by the limiting parts, and the rotating part 4 rotates relative to the fixed part 3 and is positioned by the positioning parts.

[0034] The fixing part 3 includes a fixing member 5, and the end of the fixing member 5 away from the hair dryer 2 is fixedly disposed inside the handle 1; specifically, the rotating part 4 includes a first rotating member 6 and a second rotating member 7 respectively rotatably disposed on both sides of the fixing member 5, and the end of the rotating part 4 away from the handle 1 is fixedly disposed inside the hair dryer 2; specifically, the first rotating member 6 and the second rotating member 7 are respectively provided with a first extension member and a second extension member extending towards the hair dryer 2, and the first rotating member 6 and the second rotating member 7 are respectively fixed to the hair dryer 2 through the first extension member and the second extension member.

[0035] The limiting part includes a limiting strip 8 provided on the rotating part 4 and a rotating groove 9 that cooperates with the limiting strip 8 for limiting. The rotating groove 9 is provided on both sides of the fixing member 5. Specifically, the limiting strip 8 is arranged along the raised arc of the inner wall of the first rotating member 6 and the second rotating member 7, and both ends of the limiting strip 8 are limiting ends 10.

[0036] The rotating slide 9 is provided with a limiting protrusion 11 that cooperates with the limiting end 10 to limit the movement.

[0037] The positioning part includes positioning members 12 fixedly disposed on both sides of the fixing member 5; specifically, the inner walls of the first rotating member 6 and the second rotating member 7 are provided with a plurality of positioning teeth 13 for positioning, and the positioning member 12 is provided with locking teeth 14 that cooperate with the positioning teeth 13 for positioning.

[0038] The first rotating member 6 and the second rotating member 7 are respectively provided with a first protruding shaft 15 and a second protruding shaft 16 protruding inwards; specifically, the first protruding shaft 15 is connected to the first rotating member 6 through a connecting shaft, and the first rotating member 6 and the second rotating member 7 are connected by inserting the first protruding shaft 15 and the second protruding shaft 16 on both sides of the fixing member 5. Positioning teeth 13 are evenly arranged on the outer walls of the connecting shaft and the second protruding shaft 16.

[0039] The length of the second protruding shaft 16 is two to three times the length of the first protruding shaft 15. The length of the first protruding shaft 15 inserted into the second protruding shaft 16 is about 1 / 3 to 1 / 2 of the total length of the first protruding shaft 15. The ratio of the cross-sectional radius of the first protruding shaft 15 to the cross-sectional radius of the second protruding shaft 16 is in the range of 0.5 to 1.

[0040] The fastener 5 has a through hole at its center for the first protruding shaft 15 and the second protruding shaft 16 to pass through.

[0041] Decorative covers 17 are inserted into the outer sides of both the first rotating member 6 and the second rotating member 7.

[0042] The arc length of the limiting strip 8 is at least 1 / 5 to 1 / 4 of the total arc length of the outer edge of the first rotating member 6 or the second rotating member 7.

[0043] The central angle of the limiting strip 8 is α, and the central angle of the positioning tooth 13 is β, where β ≥ α.

[0044] The handle 1 has several air inlets evenly distributed along its outer wall near the bottom. Inside the handle 1 is a control board and a motor electrically connected to the control board. The control board is located near the air inlets. Inside the blower 2 is an air duct that communicates with the inside of the handle 1. A fan blows the air entering through the air inlets into the air duct. The top of the blower 2 has an air outlet that communicates with the air duct.

[0045] The rotating part 4 has a digital display unit on at least one outer surface. When powered on, the digital display unit is electrically connected to an external power source and is used to display information such as air blowing temperature, air blowing humidity, working status, and time. The internal electrical working principle of the digital display unit is a technical means commonly used and easily conceived by those skilled in the art, and therefore will not be described in detail.

[0046] The working principle of this invention is as follows: the hair dryer 2 is manually turned so that the first rotating part 6 and the second rotating part 7 rotate on both sides of the fixed part 5. The limiting strips 8 on the first rotating part 6 and the second rotating part 7 slide in the rotating groove 9 on the fixed part 5 until the limiting ends 10 at both ends of the limiting strips 8 abut against the inner walls at both ends of the rotating groove 9. This limits the rotation angle range of the hair dryer 2 to 70°-180° between the hair dryer 2 and the handle 1. During the rotation of the hair dryer 2, the locking teeth 14 on the positioning part 12 slide on the positioning teeth 13 on the first rotating part 6 and the second rotating part 7. The locking teeth 14 engage with the positioning teeth 13 to achieve the positioning of the hair dryer 2.

[0047] The advantages of this invention are as follows: By setting a fixing part 3 and a rotating part 4 between the handle 1 and the hair dryer 2, the rotating part 4 rotates on both sides of the fixing part 3, further driving the hair dryer 2 to rotate on the handle 1. This solves the inconvenience and effort caused by the hair dryer 2's inability to rotate during use. Simultaneously, the folding of the hair dryer 2 improves the storage efficiency of the hair dryer and enhances the user experience. Furthermore, the foldable hair dryer 2 offers excellent portability and practicality. It can style your hair anytime, anywhere, making it convenient for both daily family use and travel. It is suitable for various occasions, easy to fold and unfold, and not easily deformed during normal use. During folding, the locking teeth 14 slide within the positioning teeth 13, producing a clicking sound, thus optimizing the user's feel when rotating and folding the hair dryer 2. Example

[0048] As shown in Figures 7 to 9, unlike Embodiment 1, in this embodiment, the positioning part includes a rotation locking member 18 disposed between the positioning member 12 and the rotating part 4. Specifically, the positioning member 12 has a plurality of first grooves 19 and first protrusions 20 arranged at intervals along its inner wall, and the first grooves 19 and first protrusions 20 are connected by a smooth arc. The rotation locking member 18 has a second protrusion 22 that mates with the first grooves 19 and a second groove 21 that mates with the first protrusions 20, and the second groove 21 and second protrusion 22 are connected by a smooth arc. The inner wall of the rotating part 4 has an inwardly protruding limiting cavity 23 for installing and limiting the rotation locking member 18. A spring 24 is provided at one end of the rotation locking member 18 away from the positioning member 12. One end of the spring 24 is in contact with the rotation locking member 18, and the other end of the spring 24 is in contact with the inner wall of the limiting cavity 23. Other structures are the same as in Embodiment 1.

[0049] The working principle of this embodiment is as follows: the hair dryer 2 is manually turned so that the first rotating part 6 and the second rotating part 7 rotate on both sides of the fixed part 5. The limiting strips 8 on the first rotating part 6 and the second rotating part 7 slide in the rotating groove 9 on the fixed part 5 until the limiting ends 10 at both ends of the limiting strips 8 abut against the inner walls at both ends of the rotating groove 9. During the rotation of the hair dryer 2, the second groove 21 and the second protrusion 22 on the rotating locking part 18 slide on the positioning part 12. The second groove 21 and the second protrusion 22 on the rotating locking part 18 cooperate with the first protrusion 20 and the first groove 19 on the positioning part 12 to lock and position the hair dryer 2. Example

[0050] Unlike Embodiment 1, in this embodiment, the first rotating member 6 and the second rotating member 7 are integrally formed, and the first protruding shaft 15 and the second protruding shaft 16 are integrally formed and fixedly installed through the through hole on the fixing member. Other structures are the same as in Embodiment 1. Example

[0051] Unlike Embodiment 1, in this embodiment, the engaging tooth 14 and the positioning tooth 13 are respectively located at any point where the inner wall of the first rotating member 6 and / or the inner wall of the second rotating member 7 and the inner wall of the fixed member 5 abut. The engaging tooth 14 and the positioning tooth 13 engage and position each other. During rotation, the engaging tooth 14 rotates on the positioning tooth 13, producing a sound. Other structures are the same as in Embodiment 1.
