When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] The present invention provides a handle structure 100 that can be applied to a hairdressing device 1000, such as a hair dryer, a curling iron, or a hair straightener. For ease of description, the following description will take the hair dryer as an example, and other devices can be adapted accordingly.

[0035] Specifically, see Figures 1 to 3 In this embodiment, the handle structure 100 includes a handle inner tube 1, a handle outer tube 2 and a switch structure 3; the handle outer tube 2 is sleeved on the outside of the handle inner tube 1, and an interlayer is formed between the handle inner tube 1 and the handle outer tube 2, and a through hole is opened on the handle outer tube 2, and the through hole is connected with the interlayer; the switch structure 3 includes a switch component, a transmission part connected to the switch component, and an adjustment part connected to the transmission part; wherein, a guide structure is provided on the outside of the handle inner tube 1, and the transmission part and the guide structure are movably matched, so that when the adjustment part is moved relative to the through hole under the action of external force, the transmission part is driven to move relative to the guide structure to adjust the working state of the switch component.

[0036] In this embodiment, the handle outer tube 2 is sleeved on the outside of the handle inner tube 1, and two layers of cylinders are provided to make the strength of the entire handle structure 100 better; and an interlayer is formed between the handle inner tube 1 and the handle outer tube 2, and the switch structure 3 is arranged in the interlayer, and at least a portion of it can be exposed from the through hole on the handle outer tube 2. The inner side of the handle inner tube 1 can be used for the installation of other components in the hair dryer. The switch structure 3 is isolated and arranged in the interlayer. On the one hand, it can better protect the switch structure 3, and on the other hand, it is also more convenient to assemble the switch structure 3 outside the handle inner tube 1; and a guide structure is provided in the interlayer, and the transmission part of the switch structure 3 is movably matched with the guide structure, so that when the adjustment part of the switch structure 3 is moved relative to the through hole under the action of external force, the transmission part is driven to move relative to the guide structure to adjust the working state of the switch component. During assembly, the transmission part of the switch structure 3 can be first fixed to the outside of the handle inner tube 1, and then the handle outer tube 2 can be sleeved on the outside of the handle inner tube 1, and finally the adjustment part can be clamped on the handle outer tube 2 through the through hole, so that the switch structure 3 is not limited by the inner diameter size of the handle structure 100 during assembly, and the assembly operation is more convenient and the assembly efficiency is higher.

[0037] The shapes of the handle inner tube 1 and the handle outer tube 2 are not specifically limited. The size of the interlayer between the handle inner tube 1 and the handle outer tube 2 can be adjusted according to the size of the mounting components inside the handle inner tube 1, so that there is enough mounting space inside the handle inner tube 1 while forming an interlayer between at least part of the handle inner tube 1 and the handle outer tube 2. Preferably, as Figure 1 and Figure 2 As shown in the figure, the handle inner tube 1 and the handle outer tube 2 are both roughly cylindrical, and one side of the handle inner tube 1 is partially cut to form a mounting plane. A sandwich layer is formed between the mounting plane area and the handle outer tube 2, so that the space inside the handle inner tube 1 is larger and sufficient space for installing the switch structure 3 is defined.

[0038] It is understood that the adjustment portion can move in any direction along the handle outer tube 2. According to user habits, when gripping the handle structure 100, the user typically grips the handle outer tube 2 with four fingers along its circumference, while the thumb can move flexibly. Therefore, preferably, the adjustment portion is configured to reciprocate along the axial direction of the handle outer tube 2. Specifically, at least a portion of the adjustment portion is exposed outside the through hole and can reciprocate relative to the through hole along the axial direction of the handle outer tube 2 under the action of an external force. The reciprocating axial movement of the adjustment portion relative to the handle outer tube 2 adjusts the switch member.

[0039] Further, if Figure 3 As shown in FIG, the adjustment portion includes an adjustment plate 33 and an adjustment button 34 disposed on the adjustment plate 33. The adjustment plate 33 is located inside the handle outer tube 2 and slidably mounted on the transmission portion. The adjustment plate 33 is generally plate-shaped and conforms to the inner sidewall of the handle outer tube 2, allowing for better conformity to the movement of the handle outer tube 2 during sliding. At least a portion of the adjustment button 34 is exposed outside the through-hole. When subjected to an external force, the adjustment button 34 moves relative to the through-hole, driving the adjustment plate 33 to move axially along the handle outer tube 2. The through-hole is generally elliptical in shape, and the adjustment button 34 is shaped to match the through-hole. The adjustment button 34 is located within the through-hole, with its long sides axially aligned with the handle outer tube 2. This allows the adjustment button 34 to move along the through-hole and abut against either end of the through-hole, placing the switch in two different operating states.

[0040] In order to facilitate the installation of the adjustment button 34 after the handle outer tube 2 is installed. Figure 3 and Figure 4As shown in FIG, the adjustment plate 33 is provided with mounting holes 331. The mounting holes 331 are located on opposite sides of the handle outer tube 2 along the axial direction to form a buckle portion. The adjustment button 34 is provided with two protruding hooks 341, which are engaged with the two buckles in a one-to-one correspondence. Assuming that the inner side of the handle inner tube 1 is the inner side and the outer side of the handle outer tube 2 is the outer side, the two hooks 341 extend inward from the adjustment button 34 so as to be engaged with the mounting holes 331 of the adjustment plate 33 via the two hooks 341. In the direction from outside to inside, the two sides of the mounting hole 331 form a first inverted surface gradually inclined toward the center direction of the mounting hole 331 at the corresponding buckle portion, and the end surface of each hook 341 is provided with a second guide surface gradually inclined toward the outer edge of the adjustment button 34. Under the guiding cooperation of the first guide surface and the second guide surface, the adjustment button 34 is smoother and easier to be connected to the adjustment plate 33, so the assembly is also more convenient.

[0041] As for the transmission part, the transmission part includes a limit block 31 fixedly arranged in the interlayer, and a transmission block 32 slidably arranged between the limit block 31 and the handle inner tube 1. The transmission block 32 is provided with a driving part, and the adjustment plate 33 is provided with a matching part. The driving part and the matching part cooperate with each other so that when the adjustment plate 33 moves along the axial direction of the handle outer tube 2, the transmission block 32 is driven to move along the axial direction of the handle outer tube 2 to approach or move away from the switch. When in use, the user pushes and moves the adjustment button 34, driving the adjustment plate 33 connected thereto to move along the axial direction of the handle outer tube 2. Then, under the cooperation of the driving part and the matching part, the transmission block 32 is driven to move relative to the limit block 31 to adjust the working state of the switch.

[0042] Preferably, combined Figure 3 and Figure 5As shown, the driving portion includes a transmission protrusion 321 protruding from the transmission block 32, and the mating portion includes a mating hole 332 provided on the adjustment plate 33. The transmission protrusion 321 is engaged with the mating hole 332. Specifically, the transmission protrusion 321 and the mating hole 332 are arranged in an interference fit, so that the adjustment plate 33 can better drive the transmission block 32 to move together when it moves. The transmission block 32 is generally rectangular in shape, and the transmission protrusion 321 is provided on the outward-facing surface of the transmission block 32. The transmission protrusion 321 is also square in shape to engage with the mating hole 332, making it more convenient for the transmission block 32 and the adjustment plate 33 to be connected. Moreover, the matching hole 332 is provided at the inward end of the mounting hole 331 , and the mounting hole 331 is located in the middle of the adjustment plate 33 , so that the adjustment is more balanced, and the transmission protrusion 321 is located between the two hooks 341 , which has a more compact structure and is not easy to interfere.

[0043] Further, combined again Figure 3 and Figure 5 As shown, the limiting block 31 includes a limiting base plate 311 and a plurality of limiting side plates 312 protruding from the limiting base plate 311 on the side facing the handle inner tube 1. The limiting base plate 311 is generally flat, and the plurality of limiting side plates 312 stand on one side of the limiting base plate 311. The guiding structure includes a limiting groove 11 protruding from the handle inner tube 1. The limiting groove 11 is located in the interlayer and connected to the adjustment plate 33. The limiting base plate 311 is fixed at the notch of the limiting groove 11. The transmission block 32 is located in the limiting groove 11, and the plurality of limiting side plates 312 are clamped to the outer circumference of the limiting groove 11. Preferably, three limiting side plates 312 are provided, wherein two limiting side plates 312 are arranged opposite to each other and are both extended along the axial direction of the handle outer tube 2. The two limiting side plates 312 are clamped on the outside of the limiting groove 11. Another limiting side plate 312 is located at one end of the limiting groove 11 along the axial direction of the handle outer tube 2. The three limiting side plates 312 are used to preliminarily define the positions of the limiting block 31 and the limiting groove 11, and then the limiting block 31 and the limiting groove 11 are locked and connected by screws. The screw locking points of the limiting block 31 and the limiting groove 11 can be set at two locations, which are set at two diagonal positions of the limiting block 31 and two diagonal positions of the limiting groove 11.

[0044] During assembly, the transmission block 32 can be limited first by the limit groove 11, and then the limit block 31 can be pressed on the notch of the limit groove 11. The notch of the limit groove 11 is set to face outward, and multiple limit side plates 312 are clamped on the outside of the limit groove 11 to preliminarily position the limit block 31 and the limit groove 11. Then, the limit block 31 can be connected to the limit groove 11 by screws, so that the transmission block 32 can slide in the limit groove 11, but will not fall out of the limit groove 11, thereby ensuring the relative position of the transmission block 32 and the switch component, and then the adjustment part can be assembled.

[0045] Specifically, if Figure 5 As shown in the figure, a guide groove 3111 is provided on the side of the limiting base plate 311 facing the handle outer tube 2, the notch of the guide groove 3111 is set toward the outside, the bottom of the guide groove 3111 is on the side opposite to its notch, and the bottom of the guide groove 3111 is provided with a second through hole 3112, the adjustment plate 33 is slidably arranged in the guide groove 3111, and the transmission protrusion 321 can pass through the second through hole 3112 to be inserted into the matching hole 332, so that the transmission block 32 can move together with the adjustment plate 33.

[0046] In addition, a first through hole 12 is provided at one end of the limiting groove 11 along the axial direction of the handle outer tube 2. The transmission block 32 is provided with a supporting protrusion 322 on the side facing the first through hole 12. Under the action of the adjustment portion, the transmission block 32 moves relative to the limiting groove 11, so that the supporting protrusion 322 can act on the switch member. Under the action of the adjustment button 34, the adjustment plate 33 is driven to move, thereby driving the transmission block 32 to move along the axial direction of the handle outer tube 2, so that the supporting protrusion 322 can extend from the first through hole 12 to press the switch member, and can be retracted within the limiting groove 11, thereby adjusting the switch member to at least two working states.

[0047] The present invention also provides a hairdressing device 1000, such as Figure 6 As shown in , the hairdressing device 1000 includes the aforementioned handle structure 100. This handle structure 100 facilitates assembly of the hairdressing device 1000, thereby improving assembly efficiency. The hairdressing device 1000 can be configured as a hair dryer, curling iron, or hair straightener, among others. The hairdressing device 1000 can also include a cylinder structure 200, which is connected to the handle structure 100. The handle inner cylinder 1 can be composed of two half cylinders, one of which can be integrally formed with the cylinder structure 200. This reduces the number of assembly components and enhances the connection strength between the handle structure 100 and the cylinder structure.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
