Description

Technical Field

[0001] This utility model belongs to the field of hair dryer technology, specifically relating to a structure in which the handle of a hair dryer can be rotated and folded. Background Technology

[0002] In daily life, hair dryers have gradually become an essential household appliance, serving functions such as drying and styling hair. However, most existing hair dryers have a "T"-shaped structure, which takes up a lot of space and is inconvenient to store and carry. Although existing technologies have disclosed rotating components that allow hair dryer handles to be folded and stored, these rotating components have complex structures. Typically, a fixing ring is placed outside an elastic ring, and the elastic ring has a notch. The fixing ring is connected and fixed to the handle. When rotating, the elastic ring contracts inward through the notch and deforms. However, this structure is not only complex to connect and inconvenient to assemble, but it also easily leads to insufficient elasticity of the elastic ring, causing the handle and the main body of the hair dryer to loosen, affecting the stability of the user's use. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] This invention provides a structure for a hair dryer handle that can be rotated and folded, aiming to solve the problem that the rotating component structure in the prior art is complex and easily causes the connection between the handle and the hair dryer body to loosen.

[0005] (2) Technical solution

[0006] This utility model provides a rotatable and foldable structure for a hair dryer handle, including a main body and a handle that are rotatably connected. The handle has a mounting groove, and a rotating component is provided in the mounting groove. The rotating component includes a rotating shaft, a fixed ring, and an elastic ring. The fixed ring and the elastic ring are fitted onto the rotating shaft. One end of the rotating shaft is connected to the main body, and the other end is connected to the handle. The upper surface of the elastic ring has a positioning protrusion, and the fixed ring has a positioning groove that matches the positioning protrusion.

[0007] Furthermore, the rotating shaft, the fixing ring, and the main body are integrally formed.

[0008] Furthermore, the lower end face of the elastic ring is provided with a push block, and the mounting groove is provided with a fixing groove that matches the push block, and the push block is engaged with the fixing groove.

[0009] Furthermore, two of each of the positioning protrusions and the push block are symmetrically arranged and are arranged in a cross shape on the upper and lower end faces of the elastic ring.

[0010] Furthermore, the handle includes a first housing and a second housing that are detachably connected. The first housing is provided with a first abutting block, and the second housing is provided with a second abutting block. The first abutting block and the second abutting block abut against both sides of the push block, respectively.

[0011] Furthermore, a first stop is provided on the side wall of the fixing ring, and a second stop is provided in the mounting groove that movably abuts against the first stop.

[0012] Furthermore, the diameter d1 of the outer ring of the elastic ring is greater than the diameter d2 of the outer ring of the fixed ring.

[0013] Furthermore, the rotating shaft has a through-hole structure, and the mounting groove has a through hole that communicates with the interior of the rotating shaft. The handle communicates with the interior of the main body through the through hole, the rotating shaft, and the main body.

[0014] Furthermore, the main body is provided with an integrally formed connecting part facing the handle, and the end face of the connecting part that connects to the handle is an inclined surface.

[0015] Furthermore, one end of the main body is provided with an air outlet, and the other end is provided with an air inlet, and the inclined surface is inclined downward from the side closest to the air outlet.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] A rotating assembly is provided between the handle and the main body of the hair dryer. The rotating assembly includes an elastic ring, a rotating shaft integrally formed with the main body, and a fixed ring. The fixed ring and the elastic ring are arranged in an upper and lower structure and are sleeved on the rotating shaft. The elastic ring is engaged with the handle and rotates with the handle. This not only improves the stability of the connection and makes assembly more convenient, but also simplifies the structure and reduces costs. The positioning protrusion is set on the upper end face of the elastic ring, and the positioning groove is set on the lower end face of the fixed ring, so that the elastic ring deforms downward. This changes the traditional structure of the elastic ring that shrinks inward and deforms, making the rotating assembly structure of this utility model simpler, more stable and practical.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figure 1-3As shown, this utility model provides a rotatable and foldable structure for a hair dryer handle 2, including a main body 1 and a handle 2 rotatably connected. The handle 2 has a mounting groove 23, and a rotating component 3 is provided within the mounting groove 23. The rotating component 3 includes a rotating shaft 31, a fixing ring 32, and an elastic ring 33. The fixing ring 32 and the elastic ring 33 are sequentially fitted onto the rotating shaft 31. One end of the rotating shaft 31 is connected to the main body 1, and the other end is connected to the handle 2. The upper surface of the elastic ring 33 has a positioning protrusion 331, and the fixing ring 32 has a positioning groove 321 that matches the positioning protrusion 331. The elastic ring 33 is engaged and fixed to the handle 2. When rotating, the rotating component 31... Shaft 31, the fixed ring 32, and the main body 1 are all fixed in place. The elastic ring 33 rotates with the rotation of the handle 2. Due to the influence of the positioning protrusion 331, the user needs to apply a certain force when rotating to make the elastic ring 33 slightly deform downward at the position of the positioning protrusion 331, thereby causing the positioning protrusion 331 to slide out of the positioning groove 321 and rotate. By setting the positioning protrusion 331 on the upper end face of the elastic ring 33, the elastic ring 33 is transformed from the traditional inward contraction deformation to the overall downward deformation, which can improve the stability of the elastic force of the elastic ring 33 and prevent the connection between the handle 2 and the main body 1 from becoming loose, thus affecting the folding effect.

[0031] Specifically, the rotating shaft 31 has a through hollow structure, and the mounting groove 23 has a through hole 233 that communicates with the interior of the rotating shaft 31. The rotating component 3 enters the mounting groove 23 through the through hole 233. The handle 2 communicates with the interior of the main body 1 through the through hole 233, the rotating shaft 31, and the main body 1. Since the other end of the handle 2 is connected to a wire, the wire can enter the main body 1 through the through hole 233 and the rotating shaft 31 to conduct electricity to other components inside the main body 1, and is not affected by folding and storage.

[0032] Preferably, in this embodiment, two positioning protrusions 331 and two positioning grooves 321 are symmetrically arranged. When the handle 2 rotates 180°, the positioning protrusion 331 will engage with the other positioning groove 321. At this time, the handle 2 and the main body 1 change from being perpendicular to each other to being parallel to each other, which can reduce the space occupied and achieve the effect of folding and storing the handle 2, making it convenient for users to carry and store. Compared with the structure in the traditional technology where the elastic ring 33 rotates within the fixed ring 32, the structure of this utility model is simpler and more practical. At the same time, the arrangement of the positioning protrusions 331 and the positioning grooves 321 can lock the position of the main body 1 and the handle 2 to a certain extent, preventing the main body 1 and the handle 2 from opening or folding at will.

[0033] Furthermore, the rotating shaft 31, the fixing ring 32, and the main body 1 are integrally formed, which not only makes the connection between the rotating shaft 31, the fixing ring 32 and the main body 1 more stable and improves the strength, avoids the risk of wear or loosening after long-term use due to the use of connecting parts, and extends the service life of the rotating component 3, but also simplifies the structure, reduces costs and improves assembly and production efficiency.

[0034] Furthermore, such as Figure 3-4 As shown, the lower end face of the elastic ring 33 is provided with a push block 332, and the mounting groove 23 is provided with a fixing groove 231 that is adapted to the push block 332. By engaging the push block 332 with the fixing groove 231, the fixing groove 231 forms a limiting and fixing effect on the push block 332. When the handle 2 is rotated, the fixing groove 231 will apply a force in the same direction to the push block 332, thereby causing the elastic ring 33 to rotate synchronously.

[0035] Preferably, such as Figure 5 As shown, in this embodiment, two push blocks 332 and two fixing grooves 231 are symmetrically arranged to make the elastic ring 33 more evenly stressed and rotate more smoothly. The two push blocks 332 and the two positioning protrusions 331 are arranged in a cross shape on the upper and lower end faces of the elastic ring 33, so that the position of deformation of the positioning protrusions 331 is staggered from the position of the push blocks 332, so that the elastic ring 33 has space for deformation.

[0036] Furthermore, such as Figure 2 , Figure 6-7 As shown, a first stop 322 is provided on the side wall of the fixing ring 32, and a second stop 232 is provided in the mounting groove 23 to movably abut against the first stop 322. The position of the first stop 322 is the same as the position of the positioning groove 321, and is formed by extending outward from the side wall of the fixing ring 32. The position of the second stop 232 is located on one side of another positioning groove 321, so that the second stop 232 can coincide with the position of the first stop 322 after the handle 2 rotates 180 degrees, so that the first stop 322 and the second stop 232 abut against each other to limit the rotation of the handle 2 and prevent excessive rotation and damage.

[0037] Furthermore, such as Figure 2 , Figure 8As shown, the diameter d1 of the outer ring of the elastic ring 33 is larger than the diameter d2 of the outer ring of the fixed ring 32. This increases the stability of the elastic ring 33, preventing it from becoming too elastic after prolonged use, reducing the frequency of replacement, and extending its service life. Correspondingly, the first stop block 322 is provided with an arc-shaped groove 3221 to avoid the positioning protrusion 331. The arc-shaped groove 3221 communicates with the positioning groove 321, making the elastic ring 33 and the fixed ring 32 more tightly elastically contacted.

[0038] Preferably, such as Figure 9 As shown, since the size of the mounting groove 23 is adapted to the rotating shaft 31, and the distance between the fixing ring 32 and the main body 1 is approximately equal to the thickness of the connection end face between the handle 2 and the main body 1, the handle 2 includes a detachably connected first housing 21 and a second housing 22 for easy assembly and processing. The first housing 21 and the second housing 22 split the mounting groove 23 into two parts. During assembly, the elastic ring 33 is pre-fitted onto the rotating shaft 31. Then, the main body 1 is inserted into the mounting groove 23 from the open side of the second housing 22. The first housing 21 is then connected to the second housing 22 by snap-fitting, bonding, or screwing. The rotating component 3 can then be installed into the mounting groove 23, thus assembling the rotating component 3 and the handle 2.

[0039] Preferably, in this embodiment, the first housing 21 and the second housing 22 are snap-fitted together. To further enhance the stability of the connection between the first housing 21 and the second housing 22, a connecting hole 212 is provided on the first housing 21, and a threaded hole 222 corresponding to the connecting hole 212 is provided on the second housing 22. A screw is used to enter the connecting hole 212 and screw it into the threaded hole 222 for fixation. A hole cover 213 is also provided on the connecting hole 212. The surface of the hole cover 213 is adapted to the surface of the handle 2. After assembly, the hole cover 213 is pressed into the connecting hole 212 for snap-fitting, so that the connecting hole 212 or screws are not visible from the outside, thus improving the overall aesthetics of the hair dryer.

[0040] Furthermore, such as Figure 4 As shown, a first abutment block 211 is provided in the mounting groove 23 on the first housing 21, and a second abutment block 221 is provided in the mounting groove 23 on the second housing 22. After assembly, the first abutment block 211 and the second abutment block 221 abut against the two sides of the push block 332 respectively. That is, the fixing groove 231 is composed of the first abutment block 211 and the second abutment block 221. During assembly, the push block 332 of the elastic ring 33 needs to abut against the first abutment block 211 to improve the assembly efficiency.

[0041] Preferably, such as Figure 10 As shown, the hair dryer of this utility model has an overall "T" shaped structure. The main body 1 is provided with an integrally formed connecting part 11 facing the handle 2. The end face of the connecting part 11 connected to the handle 2 is an inclined surface 4. One end of the main body 1 is provided with an air outlet 12 and the other end is provided with an air inlet 13. The inclined surface 4 is inclined downward from the side close to the air outlet 12, so that the handle 2 is located on the side of the air outlet 12 after folding and is parallel to the main body 1. This can minimize the overall space occupied by the hair dryer and make it easy to carry and store.

[0042] The working principle of this utility model is explained in detail below:

[0043] When rotating and folding, a certain force is applied to the handle 2 by hand, so that the first abutment block 211 and the second abutment block 221 inside the handle 2 jointly apply a force in the same direction to the push block 332 on the elastic ring 33, thereby driving the elastic ring 33 to rotate. When the elastic ring 33 rotates, the positioning protrusion 331 will slide out from the positioning groove 321 and cause the elastic ring 33 to deform slightly downward, so that the elastic ring 33 can continue to rotate with the handle 2. When the rotation is in place, the first stop block 322 and the second stop block 232 will abut against each other to limit the continued rotation of the handle 2. At this time, the positioning protrusion 331 will engage with another positioning groove 321, so that the handle 2 and the main body 1 are kept in a folded state, thereby achieving the effect of rotating and folding the handle 2 for storage.

[0044] The innovation of this utility model lies in the rotating component set between the handle and the main body of the hair dryer. The rotating component includes an elastic ring, a rotating shaft integrally formed with the main body, and a fixed ring. The fixed ring and the elastic ring are arranged in an upper and lower structure and are sleeved on the rotating shaft. The elastic ring is engaged with the handle and rotates with the handle. This not only improves the stability of the connection and makes assembly more convenient, but also simplifies the structure and reduces costs. The positioning protrusion is set on the upper end face of the elastic ring, and the positioning groove is set on the lower end face of the fixed ring, so that the elastic ring deforms downward. This changes the traditional structure of the elastic ring that shrinks inward and deforms, making the rotating component structure of this utility model simpler, more stable and practical.
