Technical Field

[0001] This utility model relates to hair perming devices, and more particularly to a non-circular wave hair perming device with timer function. Background Technology

[0002] A hair curler is a hair styling tool used to change the shape and texture of hair. It uses heat to deform and set the hair, achieving curls, waves, or straightening. Hair curlers typically include one or more heating elements, which can be made of metal plates, ceramic-coated plates, or other materials, and can quickly heat up to a specified temperature when powered on.

[0003] However, most products on the market currently lack precise time control functions, resulting in perming time that is too long or too short, affecting the final result and even damaging the hair.

[0004] Therefore, how to implement timing during the use of a hair curling machine to achieve time control has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a non-circular wave hair perm with timer function that controls the perming time by setting a timer button.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes an upper clamping plate, a lower clamping plate, a mounting base at the bottom, and a wiring portion located behind the mounting base. The wiring portion is detachably connected to the rear side of the lower clamping plate. The lower clamping plate is rotatably mounted on the mounting base. The mounting base is detachably connected to the rear side of the lower clamping plate and connected to the wiring portion. An upper clamping piece is provided inside the upper clamping plate, and a lower clamping piece is provided inside the lower clamping plate. A timing module is fixedly mounted on the lower clamping plate. The timing module includes a timing button and a temperature button located above the timing button. A circuit board that is linked to the timing module is also provided inside the lower clamping plate.

[0007] The present invention is further configured such that: the lower clamping piece includes a first working segment, a third working segment, and a second working segment located between the first working segment and the third working segment; the first working segment and the third working segment are both arranged in an arc shape with the opening facing upwards; the second working segment is arranged in an arc shape with the opening facing downwards; and the shape of the upper clamping piece is the same as that of the lower clamping piece.

[0008] The present invention is further configured such that: a rear baffle is provided below the lower clamping plate and a front baffle is provided above the lower clamping plate; both the front baffle and the rear baffle are detachably connected to the lower clamping plate; the timing module includes a mounting plate, which is fastened to the lower clamping plate and the circuit board is located below the mounting plate.

[0009] The present invention is further configured such that: the mounting plate is made of a material that is prone to deformation and has a plurality of limiting members protruding downwards, each of the limiting members including an insertion section and a limiting section located below the insertion section, one end of each insertion section abutting against the rear baffle, and the rear baffle is provided with a first insertion groove corresponding to each insertion section and a second insertion groove corresponding to each limiting section, the rear baffle is provided with a stop block located in each second insertion groove, and the top of each limiting section abuts against the corresponding stop block.

[0010] The present invention is further configured such that each limiting segment is arranged in a stepped manner, narrow at the bottom and wide at the top, and includes a guide surface on the left side, wherein the guide surface is inclined from top to bottom and from right to left.

[0011] The present invention is further configured such that: the mounting plate protrudes forward with a mating block, and the rear baffle is provided with a mating slot corresponding to the mating block.

[0012] The present invention is further configured such that: the lower clamping plate is provided with a rear positioning post for inserting a rear baffle and a front positioning post for inserting a front baffle protruding upward.

[0013] The present invention is further configured such that: the wiring part is made of a material that is prone to deformation and has an installation cavity and includes a connecting plug on the front side of the installation cavity; the rear side of the lower clamping plate includes a connecting section; the connecting section includes an insertion part into which the installation cavity is inserted and a connecting groove on the insertion part for the connecting plug to be inserted; the front and rear sides of the connecting plug abut against the connecting section.

[0014] The present invention is further configured such that: the mounting base includes a first mounting section and a second mounting section located in front of the first mounting section; the shape and size of the first mounting section are the same as those of the connecting section and cooperate with the mounting cavity of the wiring part; the rear side of the lower clamping plate is provided with a mating post for inserting the second mounting section; the second mounting section is provided with a positioning flange protruding downward in the circumferential direction; and the lower clamping plate is provided with a positioning groove corresponding to the positioning flange.

[0015] By adopting the above technical solution, when the power switch of the hair curler is pressed to start the hair curler, pressing the timer button and the temperature button allows the user to set the desired temperature and the required working time of the hair curler. At this time, the above instructions are transmitted to the circuit board. When the hair curler reaches the temperature, the timer can be started simultaneously, allowing the user to know how long the hair curler has been running and to reasonably arrange the hair curling operation time. When the limited time is reached, a prompt sound is emitted to stop the working of the heating element. Furthermore, since different components generate various electrical signals during the operation of the hair curler, the circuit board can process and transmit these signals. For example, the signal generated when the heating element reaches the preset temperature needs to be transmitted to the timing module through the circuit board to start the timer. At the same time, the timing signal generated by the timer also needs to be transmitted to the display module through the circuit board. When the power switch is turned off, the entire hair curler is powered off, and the timing data is cleared. In summary, by setting a timing module (including timing and temperature buttons) on the lower clamp plate, users can easily control the perming time, avoid perming time being too long or too short, improve the perming effect and safety. In addition, the wiring part is detachably connected to the lower clamp plate, which facilitates later maintenance and replacement, and improves the service life and maintenance convenience of the equipment.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-10As shown, this utility model discloses a non-circular wave hair perm with timer function, including an upper clamp plate 1, a lower clamp plate 2, a mounting base 3 located at the bottom, and a wiring part 4 located on the rear side of the mounting base 3. The wiring part 4 is detachably connected to the rear side of the lower clamp plate 2 by means of fastening or other means. The lower clamp plate 2 is rotatably mounted on the mounting base 3. The mounting base 3 is detachably connected to the rear side of the lower clamp plate 2 by means of fastening or other means and is connected to the wiring part 4. An upper clamp plate 11 is provided in the upper clamp plate 1, and a lower clamp plate 21 is provided in the lower clamp plate 2. By activating the hair perm, the heating element can be driven to heat the upper clamp plate 11 and the lower clamp plate 21, thereby achieving hair perming (this is prior art and will not be described in detail here). A timer module 22 is fixedly installed on the lower clamp plate 2. The timer module 22 includes a timer button 221 and a wiring part 4 located above the timer button 221. Temperature button 222 and switch 223 are provided. The lower clamping plate 2 is also equipped with a circuit board 23 that is linked with the timing module 22 (its linkage logic and circuit design are existing technologies and will not be described in detail here). When the power switch 223 of the hair curler is pressed to start the hair curler, pressing the timing button 221 and the temperature button 222 can set the desired temperature and the working time of the hair curler. At this time, the above instructions are transmitted to the circuit board 23. When the hair curler reaches the temperature, the timing can be started simultaneously, so that the user can know how long the hair curler has been running and reasonably arrange the hair curling operation time. When the limited time is reached, a prompt sound is issued to stop the work of the heating element. In addition, since different components generate various electrical signals during the operation of the hair curler, the circuit board 23 can process and transmit these signals. For example, the signal generated when the heating element reaches the preset temperature needs to be transmitted to the timing module 22 through the circuit board 23 to start the timer. At the same time, the timing signal generated by the timer also needs to be transmitted to the display module through the circuit board 23. When the power switch 223 is turned off, the entire hair curler is powered off and the timing data is cleared. In summary, by setting the timing module 22 (including the timing button 221 and the temperature button 222) on the lower clamp plate 2, users can easily control the hair curling time, avoid the hair curling time being too long or too short, improve the hair curling effect and safety. In addition, the wiring part 4 is detachably connected to the lower clamp plate 2, which facilitates later maintenance and replacement, and improves the service life and maintenance convenience of the equipment.

[0034] The lower clamping piece 21 includes a first working section 211, a third working section 213, and a second working section 212 located between the first working section 211 and the third working section 213. The first working section 211 and the third working section 213 are both arranged in an arc shape with the opening facing upwards, and the second working section 212 is arranged in an arc shape with the opening facing downwards. The upper clamping piece 11 has the same shape as the lower clamping piece 21. The upper clip 11 has the same shape as the lower clip 21, ensuring a close fit and even heating when clamping the hair, thus improving the quality of the perm; 2. Since the first working section 211 and the third working section 213 are arc-shaped with the opening facing upwards and the second working section 212 is arc-shaped with the opening facing downwards, after separating the upper plate 1 and the lower plate 2, the hair is placed between the upper clip 11 and the lower clip 21, which are in a heated state, to set this part of the hair. Compared with the operation of a cylindrical perm that requires wrapping the hair around it, the segmented arc-shaped upper clip 11 and lower clip 21 design allows for a more convenient and efficient perm operation.

[0035] The lower clamping plate 2 is provided with a rear baffle 24 below the lower clamping piece 21 and a front baffle 25 above the lower clamping piece 21. Both the front baffle 25 and the rear baffle 24 are detachably connected to the lower clamping plate 2. The timing module 22 includes a mounting plate 224, which is fastened to the lower clamping plate 2. The circuit board 23 is located below the mounting plate 224, which protects the circuit board 23 and facilitates installation and maintenance.

[0036] Preferably, the mounting plate 224 is made of a material that is easily deformable, such as rubber, and has a plurality of limiting members 5 protruding downward. Each limiting member 5 includes an insertion section 51 and a limiting section 52 located below the insertion section 51. One end of each insertion section 51 abuts against the rear baffle 24, and the rear baffle 24 is provided with a first insertion groove 242 corresponding to each insertion section 51 and a second insertion groove 243 corresponding to each limiting section 52. The rear baffle 24 is provided with abutting blocks 244 located in each of the second insertion grooves 243. The top of each limiting section 52 abuts against the corresponding abutting block 244. During the process of installing the mounting plate 224 onto the lower clamping plate 2, each limiting member 5 on the mounting plate 224 will face the rear baffle plate fixed to the lower clamping plate 2. The first insertion slots 242 move, and the first to reach the first insertion slot 242 are the limiting segments 52 located below each insertion segment 51. Each limiting segment 52 needs to forcibly pass over the corresponding abutment block 244 to reach the corresponding second insertion slot 243. When the bottom of each abutment block 244 is above the corresponding limiting segment 52 and abuts against it, one side of each insertion segment 51 abuts against the rear baffle 24 and is located in the corresponding first insertion slot 242. At this time, without the action of external force, each limiting segment 52 cannot move upward over the corresponding abutment block 244, so that the mounting plate 224 is stably located on the rear baffle 24, and the circuit board 23 is stably located below the mounting plate 224 to achieve cooperation with each button.

[0037] Preferably, each limiting segment 52 is arranged in the form of a stepped platform that is narrower at the bottom and wider at the top, and includes a guide surface 521 on the left side. The guide surface 521 is inclined from top to bottom and from right to left. Since the bottom area of ​​each limiting segment 52 is smaller than the top area and there is an inclined guide surface 521, when the mounting plate 224 is facing down and each limiting segment 52 enters the corresponding second insertion slot 243, the bottom of each limiting segment 52 can be more smoothly aligned with the second insertion slot 243, thereby forcibly passing over the corresponding abutment block 244 to realize that each limiting segment 52 enters the corresponding second insertion slot 243.

[0038] The mounting plate 224 has a protruding frontal fitting block 2241, and the rear baffle 24 has a corresponding fitting slot 241. Therefore, when the mounting plate 224 is inserted into the lower baffle, the front fitting block 2241 must first be inserted into the fitting slot 241, so that the front side of the fitting block 2241 is restricted by the rear baffle 24 and cannot move forward. Thus, each limiting member 5 can prevent the mounting plate 224 from moving up and down or rotating without the action of external force, and the fitting block 2241 prevents the mounting plate 224 from moving back and forth.

[0039] The lower clamping plate 2 is provided with a rear positioning post 26 for inserting the rear baffle 24 and a front positioning post 27 for inserting the front baffle 25. Since the rear positioning post 26 can insert the rear baffle 24 and the front positioning post 27 can insert the front baffle 25, the relative positions of the front baffle 25 and the rear baffle 24 on the lower clamping plate 2 are determined, thus facilitating their fixation to the lower clamping plate 2.

[0040] The wiring part 4 is made of a material that is easily deformable, such as rubber, and has a mounting cavity 41 and includes several connecting blocks 42 circumferentially on the front side of the mounting cavity 41. The rear side of the lower clamping plate 2 includes a connecting section 28, which includes an insertion part 281 for inserting into the mounting cavity 41 and a connecting groove 283 on the insertion part 281 for inserting the connecting blocks 42. The connecting blocks 42 abut against the connecting section 28 on both the front and rear sides. The lower clamping plate 2 is then connected to the wiring part 4. During the process, the connecting section 28 of the lower clamping plate 2 will first enter the mounting cavity 41. Since the wiring part 4 is located on the front side of the mounting cavity 41 and the connecting plug 42 is set, the connecting section 28 needs to be forcibly pushed past the connecting plug 42 during the process of installing into the mounting cavity 41. When the connecting plug 42 is located in the circumferential position of the connecting groove 283, the connecting plug 42 can fall into the connecting groove 283, so that the relative position of the wiring part 4 and the connecting section 28 is determined without the action of external force.

[0041] The mounting base 3 includes a first mounting section 31 and a second mounting section 32 located in front of the first mounting section 31. The shape and size of the first mounting section 31 are the same as those of the connecting section 28 and it mates with the mounting cavity 41 of the wiring part 4. The lower clamping plate 2 has a mating post 282 protruding upward from its rear side for inserting the second mounting section 32. The second mounting section 32 has a positioning flange 321 protruding downward circumferentially. The lower clamping plate 2 has a positioning groove 29 corresponding to the positioning flange 321. Because the shape and size of the first mounting section 31 are the same as those of the connecting section 28, the mounting base 31 is equipped with a first mounting section 31 and a second mounting section 32 located in front of the first mounting section 31. Since the first mounting section 31 is the same size and shape as the connecting plug 42, it is similarly inserted into the mounting cavity 41 of the wiring part 4. Since the connecting plug 42 is sleeved around the first mounting ring, the relative position of the first mounting section 31 and the wiring part 4 is determined without the action of external force. At this time, the mating post 282 on the lower clamping plate 2 can insert the second mounting section 32 and the positioning flange 321 on the second mounting section 32 can enter the positioning groove 29 on the lower clamping plate 2, thereby further determining the position of the two.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
