Description

Technical Field

[0001] This invention relates to the field of hair dryer technology, specifically to a hair dryer that is easy to fold and carry. Background Technology

[0002] A hair dryer, also known as a hairdryer, consists of a set of heating wires and a high-speed small fan. When powered on, the heating wires generate heat, and the air blown out by the fan passes through the heating wires and becomes hot air. If only the small fan rotates but the heating wires are not hot, then only air will be blown out without heat. As a small household appliance, hair dryers can help people dry their hair quickly, prevent excessive moisture in the hair from affecting their health, and also help people create the hairstyles they want.

[0003] Existing hair dryers use heating wires to generate hot air to increase drying efficiency. However, with prolonged use, the heating wires accumulate a lot of heat, causing the outer casing to overheat. This means users need to wait for the hair dryer to cool down naturally after use before storing and carrying it, significantly impacting its overall portability and making it difficult to pack away quickly after use. Therefore, we propose a foldable hair dryer for easy carrying.

[0004] Combining the issues mentioned above, we find that existing foldable and portable hair dryers on the market cannot simultaneously avoid the problems mentioned above when in use. Even if they can be solved, they require the use of external tools, thus failing to achieve the desired effect. Therefore, we propose a foldable and portable hair dryer. Summary of the Invention

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 Please see Figures 1-11 The present invention provides a technical solution: a hair dryer that is easy to fold and carry, including a hair dryer mechanism 1, wherein the hair dryer mechanism 1 includes a cylindrical body 11, a rotating motor 12 is fixedly connected to the inner wall of the cylindrical body 11, a fan blade 13 is fixedly connected to the output end of the rotating motor 12, the fan blade 13 is located inside the cylindrical body 11, two heating resistance wires 14 are fixedly connected to the inner wall of the cylindrical body 11, both heating resistance wires 14 are located on the right side of the fan blade 13, and a heat insulation mechanism 2 is provided below the cylindrical body 11; The heat insulation mechanism 2 includes a heat insulation shielding unit 21, which is located below the cylinder 11 and is used to insulate the heat of the cylinder 11.

[0023] As a further definition of the heat insulation mechanism 2 of the present invention, the heat insulation shielding unit 21 includes a handle 2101, which is located below the cylinder 11. A rotating cylinder 2102 is rotatably connected inside the handle 2101. A shielding cover 2103 is provided on the left side of the rotating cylinder 2102. A support frame 2111 is fixedly connected to the bottom end of the rotating cylinder 2102. The left side of the support frame 2111 is fixedly connected to the right side of the shielding cover 2103. A telescopic cover 2104 is slidably connected inside the shielding cover 2103. A plurality of limiting springs 2110 are fixedly connected to the bottom surface of the telescopic cover 2104. The bottom ends of the plurality of limiting springs 2110 are all fixedly connected to the inner bottom wall of the shielding cover 2103. A fixing frame 2105 is fixedly connected to the upper surface of the telescopic cover 2104. The bottom surface of the fixing frame 2105 is in contact with the upper surface of the shielding cover 2103. A snap-fit ​​block 210 is slidably connected inside the fixing frame 2105. 6. A snap-fit ​​groove 2107 is provided on the upper part of the outer surface of the cylinder 11. Two snap-fit ​​springs 2108 are fixedly connected to the left side of the snap-fit ​​block 2106. The other ends of the two snap-fit ​​springs 2108 are fixedly connected to the inner side wall of the fixing frame 2105. A pull rod 2109 is fixedly connected to the left side of the snap-fit ​​block 2106. The pull rod 2109 is slidably connected to the inside of the fixing frame 2105. The left end of the pull rod 2109 extends through to the left side of the fixing frame 2105. By setting the heat insulation shielding unit 21 of the heat insulation mechanism 2, the cylinder 11 can be shielded and stored after use, preventing the residual heat on the cylinder 11 from affecting the convenience of storing and carrying the hair dryer. This allows the hair dryer to be quickly stored and carried without waiting for the cylinder to cool down naturally after use, without burning the hands. This greatly improves the overall convenience of the hair dryer, allowing it to be quickly stored and carried after use.

[0024] Three sliding blocks 2112 are fixedly connected to the outer surface of the telescopic cover 2104. Each sliding block 2112 is slidably connected to the inside of the shield 2103. The sliding blocks 2112 slide inside the shield 2103, which can limit the sliding distance of the telescopic cover 2104 inside the shield 2103 and prevent the telescopic cover 2104 from becoming loose from the shield 2103. The left end of the pull rod 2109 is fixedly connected to a limiting plate 2113. Several anti-slip grooves 2114 are provided on the left side of the limiting plate 2113. The limiting plate 2113 can restrict the position of the pull rod 2109 inside the fixed frame 2105. At the same time, the limiting plate 2113 and the anti-slip grooves 2114 can increase the convenience of manual operation of the pull rod 2109.

[0025] The specific implementation of this embodiment is as follows: The rotating motor 12, in conjunction with the cylinder 11, drives the fan blades 13 to rotate, generating airflow. When the airflow passes through the heating wire 14, it is heated by the heat provided by the heating wire 14, allowing hot air to be blown out from the right side of the cylinder 11, enabling the hair dryer to work normally to dry hair or clothes. When the hair dryer needs to be stored and carried after prolonged use, first rotate the rotating cylinder 2102 counterclockwise 180 degrees inside the handle 2101, and then use the support frame 2111 to cover it. Rotate cover 2103 to directly below cylinder 11, then turn handle 2101 counterclockwise by 90 degrees to keep handle 2101 parallel to cylinder 11. At this time, pull cover 2103 to the left to cover cylinder 11. Rotating cylinder 2102 will also slide to the left inside handle 2101. Pull the fixing bracket 2105 to the left to pull telescopic cover 2104 out from inside cover 2103, further covering cylinder 11, until the locking block 2106 is perpendicular to the locking groove 2107, and the locking spring 2... The elastic-fit fixing bracket 2105 provided by 108 can push the locking block 2106 into the locking groove 2107 to fix the position of the pulled-out cover 2103 and telescopic cover 2104. When the cylinder 11 needs to be used again, simply pull the locking block 2106 upward with the pull rod 2109 in conjunction with the limiting plate 2113 and the anti-slip groove 2114 to pull the locking block 2106 out of the locking groove 2107 and release the limiting on the telescopic cover 2104, so that the telescopic cover 2104 can retract. The shield 2103 is placed inside the shaft, and the shield 2103 and handle 2101 are restored to their original positions. This allows the hair dryer to be stored after use by shielding the shaft 11, preventing residual heat from affecting the convenience of storing and carrying the hair dryer. This also allows the hair dryer to be quickly stored and carried without waiting for the shaft to cool down naturally, without burning hands. This greatly improves the overall convenience of the hair dryer, making it easy to store and carry after use.

[0026] Example 2 Please see Figures 1-11 The present invention provides a technical solution: a hair dryer that is easy to fold and carry. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0027] As a further limitation of the heat insulation mechanism 2 of the present invention, the heat insulation mechanism 2 also includes a heat dissipation and cooling unit 22, which is located inside the heat insulation shielding unit 21 and is used to reduce the temperature of the cylinder 11. The heat dissipation and cooling unit 22 includes a capacitor 2201. The upper surface of the capacitor 2201 is fixedly connected to the inner top wall of the handle 2101. A first gear disk 2202 is slidably connected inside the handle 2101. A second gear disk 2203 is fixedly connected to the top of the rotating cylinder 2102 and is slidably connected inside the handle 2101. The upper surface of the second gear disk 2203 meshes with the bottom surface of the first gear disk 2202. Four auxiliary springs 2204 are fixedly connected to the upper surface of the first gear disk 2202. The top of each auxiliary spring 2204 is fixedly connected to the inner top wall of the handle 2101. A connecting cylinder 2205 is fixedly connected to the bottom surface of the shield 2103. The connecting cylinder 2205 is equipped with a small motor 2206. The small motor 2206 is electrically connected to the capacitor 2201 through a wire. The output end of the small motor 2206 is fixedly connected to a cooling fan 2207. The cooling fan 2207 is located inside the connecting cylinder 2205. By setting up a heat dissipation and cooling unit 22, after the heat insulation and shielding unit 21 shields the cylinder 11, the residual heat inside the cylinder 11 can be quickly removed by increasing the air flow rate inside the cylinder 11 with wind power. This effectively reduces the overheating phenomenon of the cylinder 11 after use, and further facilitates the user to quickly store and carry the hair dryer after use, making the portability of the hair dryer even better. A positioning frame 2208 is fixedly connected to the outer surface of the small motor 2206. The outer surface of the positioning frame 2208 is fixedly connected to the inner wall of the connecting cylinder 2205. The positioning frame 2208 can limit the position of the small motor 2206 inside the connecting cylinder 2205, increase the operating stability of the small motor 2206, and make the small motor 2206 more stable and reliable when in use. An exhaust hood 2209 is fixedly connected to the inner wall of the connecting cylinder 2205. The bottom surface of the exhaust hood 2209 is provided with several exhaust slots 2210. The exhaust hood 2209, together with the exhaust slots 2210, can ensure that the gas can smoothly enter the interior of the connecting cylinder 2205, while preventing large external impurities from entering the connecting cylinder 2205, so that large impurities are less likely to enter the connecting cylinder 2205 and affect the operation of the small motor 2206. A connecting wire 2211 is fixedly connected to the bottom surface of the rotating cylinder 2102. The other end of the connecting wire 2211 is electrically connected to a plug 2212 via a wire. The rotating motor 12, the heating element 14, and the capacitor 2201 are all electrically connected to the connecting wire 2211 via wires. The connecting wire 2211, together with the plug 2212, can ensure that the rotating motor 12 and other electrical facilities can be powered smoothly, allowing the hair dryer to blow air smoothly.

[0028] The specific implementation of this embodiment is as follows: First, the rotating motor 12, the heating element 14, and the capacitor 2201 are connected to the power supply using the connecting wire 2211 and the plug 2212, ensuring the normal operation of the rotating motor 12, the heating element 14, and the capacitor 2201. When the rotating cylinder 2102 rotates inside the handle 2101, the meshing of the first gear 2202 and the second gear 2203, combined with the elastic force provided by the auxiliary spring 2204, provides a certain resistance to the rotation of the rotating cylinder 2102, preventing excessive loosening after rotation and increasing the stability of the rotating cylinder 2102 and the shield 2103 when adjusting their positions. At the same time, the extension and retraction of the auxiliary spring 2204 will not affect the up-and-down sliding of the rotating cylinder 2102 inside the handle 2101. When the plug 2212 and the connecting wire... After 2211 is connected to power, capacitor 2201 will quickly charge and briefly store some electrical energy. Then, when the shield 2103 covers the body 11 and the plug 2212 is disconnected from the external power source, the small amount of electrical energy inside capacitor 2201 will drive the small motor 2206 to rotate for a short time, which in turn drives the cooling fan 2207 to rotate, increasing the air circulation speed inside the body 11. This allows the heat inside the body 11 to be quickly dissipated to the outside. After a period of time, the power inside capacitor 2201 is exhausted and the small motor 2206 stops running. This allows the cooling of the body 11 to be carried out while the body 11 is being stored, without having to reconnect to the power source and wait. This further increases the portability of the hair dryer, making it convenient for users to quickly store and carry the hair dryer after use, and making the portability of the hair dryer even more superior.

[0029] Example 3 Please see Figures 1-11 The present invention provides a technical solution: a hair dryer that is easy to fold and carry. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0030] As a further limitation of the folding mechanism 3 of the present invention, the folding mechanism 3 is provided above the heat insulation shielding unit 21. The folding mechanism 3 is used in conjunction with the heat insulation mechanism 2. The folding mechanism 3 is used to fold and reduce the overall volume of the cylinder 11. The folding mechanism 3 includes a connecting frame 301, the bottom surface of which is fixedly connected to the top of the handle 2101. A connecting shaft 302 is rotatably connected inside the connecting frame 301. A connecting seat 303 is fixedly connected to the outer surface of the connecting shaft 302. The upper surface of the connecting seat 303 is fixedly connected to the bottom of the outer surface of the cylinder 11. A gear 304 is fixedly connected to the outer surface of the connecting shaft 302. A compression spring 305 is fixedly connected to the inner bottom wall of the connecting frame 301. A toothed seat 306 is fixedly connected to the other end of the compression spring 305. The toothed seat 306 meshes with the gear 304. A baffle 307 is fixedly connected to the left side of the connecting seat 303. The right side of the baffle 307 contacts the left side of the connecting frame 301. A snap-fit ​​bracket 308 is fixedly connected to the left side of the connecting frame 301. A snap-fit ​​plate 309 is slidably connected inside the baffle 307. The bottom end of the snap-fit ​​plate 309 penetrates the baffle 301. 07 is snapped into the inside of the snap-fit ​​bracket 308. Two return springs 310 are fixedly connected to the upper surface of the snap-fit ​​plate 309. The other end of each of the two return springs 310 is fixedly connected to the inner top wall of the baffle 307. A pusher 311 is fixedly connected to the left side of the snap-fit ​​plate 309. The pusher 311 is slidably connected inside the baffle 307. By setting the folding mechanism 3, the handle 2101 of the hair dryer can be folded at ninety degrees parallel to the body 11. At the same time, the position of the handle 2101 after folding can be limited, so that the handle 2101 can be quickly folded and stored when the hair dryer is taken out, reducing the storage space occupied by the hair dryer when it is stored. This effectively improves the folding and carrying convenience of the hair dryer. At the same time, the handle 2101 can also be fixed and limited after unfolding. While ensuring that the handle 2101 can be folded and carried, the stability and reliability of the handle 2101 when unfolded and used are increased. The compression spring 305 has a telescopic rod 312 inside. The telescopic end of the telescopic rod 312 is fixedly connected to the bottom surface of the tooth seat 306, and the bottom end of the telescopic rod 312 is fixedly connected to the inner bottom wall of the connecting frame 301. The telescopic rod 312 can prevent the compression spring 305 from excessively deviating without affecting the smooth extension and retraction of the compression spring 305, thereby improving the stability of the compression spring 305.

[0031] The specific implementation method of this embodiment is as follows: First, manually push the locking plate 309 upward using the pusher 311, so that the locking plate 309 slides upward inside the baffle 307 and forces the return spring 310 to contract. At this time, the locking plate 309 and the locking frame 308 are disengaged. Then, manually turn the handle 2101 counterclockwise, so that the connecting frame 301 and the connecting seat 303 rotate on the connecting shaft 302, thereby forcing the tooth seat 306 to disengage from the gear 304 and quickly re-engage with it under the elastic force provided by the compression spring 305, until the handle 2101 is parallel to the cylinder 11 and the folding of the handle 2101 is completed. Under the push of the compression spring 305, the tooth seat 306 is still engaged with the gear 304, which can provide a certain resistance to the connecting frame 301 and the handle 2101, making it less likely for the handle 2101 to fall after folding, increasing the stability of the handle 2101 after folding. To ensure the proper functioning of the shield 2103 covering the body 11, when the handle 2101 needs to be unfolded for use, simply turn the handle 2101 clockwise by 90 degrees until the left side of the connecting bracket 301 contacts the right side of the baffle 307. Then, let the snap plate 309 snap into the snap bracket 308 to fix the position of the handle 2101. This allows the handle 2101 to be folded 90 degrees parallel to the body 11 of the hair dryer. It also limits the position of the handle 2101 after folding, allowing the handle 2101 to be quickly folded and stored when the hair dryer is taken out, reducing the storage space occupied by the hair dryer and effectively improving the convenience of folding and carrying the hair dryer. At the same time, the handle 2101 can also be fixed and limited after unfolding, ensuring that the handle 2101 can be folded and carried while increasing the stability and reliability of the handle 2101 when unfolded.
