[0045] The utility model provides a universal hair dryer, which is suitable for the application scenario of blowing hair. It can effectively solve the problem that the air supply angle of the existing hair dryer is too single and cannot meet the diverse usage needs.

[0046] The utility model provides a universal hair dryer, which comprises a hair dryer body, an air outlet sleeve, and a hollow steering component connecting the hair dryer body and the air outlet sleeve.

[0047] The universal hair dryer provided by the present invention has a hollow steering component that can be adjusted at multiple angles between the hair dryer body and the air outlet sleeve, thereby achieving multi-angle air outlet adjustment to meet diverse usage needs.

[0048] As in Examples 1 and 2, various implementations of the hollow steering assembly of the present invention will be introduced below with reference to the accompanying drawings.

[0049] Example 1

[0050] See also Figure 1 and Figure 2This embodiment provides a hollow steering assembly 3 that uses a ball head connection structure to achieve multi-angle adjustment. Specifically, the hollow steering assembly 3 includes a first end joint 301 plugged into the hair dryer body 1, a second end joint 302 plugged into the air outlet sleeve 2, and several intermediate joints 303 located between the first end joint 301 and the second end joint 302 and connected in sequence.

[0051] Each intermediate joint 303 has a ball head 3031 at one end and a spherical groove 3032 at the other end for receiving the ball head 3031 of another joint; the spherical groove 3032 is slidably connected to the corresponding ball head 3031. Furthermore, the ball head 3031 is provided with an air hole 3033 connected to the spherical groove 3032, so that the hair dryer body 1 can supply air to the air outlet sleeve 2 through each spherical groove 3032 and the air hole 3033.

[0052] The matching design of the spherical groove 3032 and the ball head 3031 allows each intermediate joint 303 to be adjusted in multiple directions. The user can adjust the air outlet direction according to their needs, whether it is straight blowing, side blowing or upward blowing, it can be easily achieved.

[0053] Optionally, the groove wall of the spherical groove 3032 and / or the surface of the ball head 3031 is coated with a sealing coating. For example, the sealing coating may be a Teflon coating, a polyurethane coating, or a nano coating.

[0054] In this embodiment, each of the joint components includes two symmetrically arranged half-joints, and the two half-joints are locked by bolts.

[0055] It is understandable that if the joint is an integrated structure, it would be difficult to fit the ball head 3031 into the corresponding spherical groove 3032. Therefore, the joint is configured to be composed of two half joints, so that the ball head 3031 is first placed in one half joint, and then the two half joints are locked together by bolts, etc., to complete the assembly of the hollow steering assembly 3.

[0056] Optionally, the ball head 3031 is provided with a notch 3031a; Figure 2As shown, when the ball head 3031 is inserted into the spherical groove 3032, the notch 3031a of the ball head 3031 can make the air duct through the air hole 3033 larger; especially when the intermediate joint 303 is bent, the notch 3031a of the ball head 3031 can make the air duct between the ball head 3031 and the spherical groove 3032 larger, and the air flow between the hair dryer body 1 and the air outlet sleeve 2 is smoother and more fluent, and the air volume of the air outlet sleeve 2 is larger and the wind speed is faster; this solves the problem that the air duct of the intermediate joint 303 is greatly reduced when the ball head 3031 and the spherical groove 3032 are bent.

[0057] See also Figure 3 In this embodiment, the hair dryer body 1 is provided with an air supply hole 101 for inserting the first end joint 301. The first end joint 301 is inserted into the air supply hole 101 and is rotatably connected to the hair dryer body 1. A rotating boss 3011 is provided on the circumferential surface of the end of the first end joint 301 that is inserted into the air supply hole 101. The wall of the air supply hole 101 is provided with a first blocking boss 102 for limiting the rotating boss 3011 from further forward rotation, and a second blocking boss 103 for limiting the rotating boss 3011 from further reverse rotation.

[0058] The rotating boss 3011 can only rotate between the first blocking boss 102 and the second blocking boss 103, and cannot rotate 360 ​​degrees without restriction. The advantage of this design is that it can prevent the internal conductive wire from being broken or damaged due to excessive rotation. Optionally, the rotating boss 3011 can rotate at an angle of 0°-270°.

[0059] In summary, the hollow steering assembly 3 provided in this embodiment has the following advantages:

[0060] ① Through the combination of the ball joint structure and the intermediate joint 303, the hollow steering assembly 3 can achieve multi-angle air outlet adjustment to meet the user's different blowing needs, such as straight blowing, side blowing or upward blowing;

[0061] ② The sliding sealing connection design between the spherical groove 3032 and the ball head 3031 makes the adjustment of the air outlet sleeve 2 very flexible, and the user can easily adjust the air outlet direction according to personal preferences and usage scenarios;

[0062] ③ Using a sealing coating to improve the sealing performance between the spherical groove 3032 and the ball head 3031 reduces gas leakage and improves the efficiency of the hair dryer;

[0063] ④ The joint is designed as two symmetrically arranged half joints, which can easily install the ball head 3031 into the spherical groove 3032 and lock it with bolts, simplifying the assembly process and facilitating future maintenance and replacement;

[0064] ⑤ Two blocking bosses are provided to limit the rotation angle of the first end joint part 301, thereby preventing the internal conductive wire from being broken and damaged due to excessive rotation, thereby improving the safety of the product.

[0065] Example 2

[0066] See also Figures 4 to 6 This embodiment provides a hollow steering assembly 3 that uses a rotating shaft connection structure to achieve multi-angle adjustment. Specifically, the hollow steering assembly 3 includes a first end joint 301 plugged into the hair dryer body 1, a second end joint 302 plugged into the air outlet sleeve 2, and several intermediate joints 303 located between the first end joint 301 and the second end joint 302 and connected in sequence.

[0067] In this embodiment, the intermediate joint component 303 includes a thin-walled sleeve 3034 and a thick-walled sleeve 3035; wherein, the end face of the thick-walled sleeve 3035 is provided with an annular groove 3036 for inserting the thin-walled sleeve 3034 of another intermediate joint component 303; the two adjacent intermediate joint components 303 are rotationally connected through a rotating shaft 3037.

[0068] It can be understood that the two adjacent intermediate joints 303 are rotatably connected via a rotating shaft 3037. Therefore, each intermediate joint 303 can be deflected at a certain angle relative to the adjacent upper intermediate joint 303. By rotating multiple intermediate joints 303, multi-angle adjustment of the air outlet direction can be achieved.

[0069] Optionally, a limiting shaft 3038 is fixedly provided on the inner side of the thin-walled sleeve 3034 , and a limiting inclined guide groove 3039 is provided on the thick-walled sleeve 3035 for inserting the corresponding limiting shaft 3038 .

[0070] When two adjacent intermediate joints 303 rotate relative to each other around the rotation axis 3037 to achieve blowing reversal, the limiting shaft 3038 will shift in the limiting inclined guide groove 3039. The limiting inclined guide groove 3039 can limit the displacement distance of the limiting shaft 3038 relative to the adjacent intermediate joint 303, thereby avoiding the situation where the rotation angle between the two adjacent intermediate joints 303 is too large, causing the thin-walled sleeve 3034 to detach from the corresponding annular groove 3036.

[0071] In this embodiment, the joint parts achieve small-range rotation through each rotating shaft 3037. Optionally, the relative rotation angle range between two adjacent intermediate joint parts 303 is 0°-9°. Experiments show that when rotating within this angle range, the thin-walled sleeve 3034 moves smoothly in the corresponding annular groove 3036 and is not easy to get stuck.

[0072] In this embodiment, the connection structure between the hair dryer body 1 and the first end joint 301 is the same as that in Example 1, and will not be repeated here.

[0073] In summary, the universal hair dryer provided in this embodiment has the following advantages:

[0074] ① Two adjacent intermediate joints 303 are connected by a rotating shaft 3037, which enables multi-angle adjustment of the air outlet direction, thereby improving the flexibility and adaptability of the hair dryer;

[0075] ② The design of the limiting shaft 3038 and the limiting oblique guide groove 3039 effectively limits the rotation angle of adjacent intermediate joints 303, avoids connection failure caused by excessive rotation angle, and improves the stability of the connection.

[0076] Example 3

[0077] See also Figures 7 to 9 This embodiment provides a hollow steering assembly 3 that uses a bellows connection structure to achieve multi-angle adjustment. Specifically, the hollow steering assembly 3 includes a first end joint 301 plugged into the hair dryer body 1, a second end joint 302 plugged into the air outlet sleeve 2, and several intermediate joints 303 located between the first end joint 301 and the second end joint 302 and connected in sequence; wherein each of the intermediate joints 303 is connected in sequence to form a hollow bellows.

[0078] In this embodiment, the first end joint 301 is fixedly connected to the hair dryer body 1, and the second end joint 302 is fixedly connected to the air outlet sleeve 2. The intermediate joints 303 are connected in sequence to form a hollow bellows. An air duct is formed inside the hollow bellows. The hair dryer body 1 supplies air to the air outlet sleeve 2 through the air duct. The hollow bellows can be bent arbitrarily, so that the air supply angle of the air outlet sleeve 2 can be flexible and diverse.

[0079] In summary, the hollow steering assembly 3 provided in this embodiment has the following advantages:

[0080] By rotating the hollow bellows, the air supply angle of the universal hair dryer can be changed to meet the user's diverse blowing needs, and the structure of the hollow steering component 3 in this embodiment is easy to manufacture, which reduces the manufacturing cost of the universal hair dryer.
