Description

Technical field

[0001] The utility model relates to the technical field of hair straightening combs, in particular to a hair straightening comb. [Background Technology]

[0002] In modern society, people are paying more and more attention to managing their hair. Traditional combs can only smooth hair, but cannot straighten it. Therefore, straightening combs have emerged. Straightening combs usually have a built-in heating module that heats the comb teeth. When the heated comb teeth come into contact with the hair, they can change the hair's protein structure and straighten the hair.

[0003] Existing hair straightening combs typically have multiple comb tooth assemblies, and these are generally not designed with modularity in mind. Each comb tooth assembly must be assembled separately during assembly. This lack of modularity requires extremely high assembly precision, making assembly of the comb tooth assemblies difficult.

[0021] Compared with the prior art, the hair straightening comb provided by the present invention has the following advantages:

[0022] 1. The present invention provides a hair straightening comb comprising a first housing and a second housing that are detachably connected. The first housing and the second housing form a receiving space. The first housing has a clearance opening and a first comb tooth hole.

[0023] A first comb assembly, comprising a first comb structure and a second comb structure, wherein one end of the first comb structure and the second comb structure is accommodated in the accommodating space, and the other end is a comb-shaped structure, which passes through the first comb hole and is exposed to the first shell;

[0024] The second comb assembly has one end housed within the space and detachably connected to the first comb assembly, and the other end exposed to the first housing through the clearance opening. In this embodiment, by forming the first and second comb structures into two modules, the modular design allows each to fit into its corresponding first comb hole during assembly, reducing assembly difficulty.

[0025] 2. The first comb tooth structure of the present embodiment includes a first base and first comb teeth connected to the first base. The second comb tooth structure includes a second base and second comb teeth connected to the second base. The first base and the second base are both disposed within the accommodating space. The end of the first comb teeth away from the first base and the end of the second comb teeth away from the second base can both pass through corresponding first comb tooth holes and be exposed in the first housing. When the first and second comb teeth pass through the corresponding first comb tooth holes and are exposed in the first housing, the first comb tooth holes in the first housing can also limit the entire first and second comb tooth structures, thereby improving the installation stability of the first and second comb tooth structures.

[0026] 3. The first housing of the present invention includes a comb head and a comb handle connected to each other. A first comb tooth hole is defined on a side of the comb head away from the second housing. The first comb teeth and the second comb teeth both include long comb teeth and short comb teeth.

[0027] The first comb holes consist of one row of long comb holes and two rows of short comb holes. The long comb holes are arranged along the outer perimeter of the comb head, and the two rows of short comb holes are located on either side of the long comb holes. The long comb teeth are longer than the short comb teeth after passing through the long comb holes. The design of one row of long comb teeth and two rows of short comb teeth has a larger number of short comb teeth, making it easier to comb hair away from the scalp, making hair appear smoother.

[0028] 4. The second comb assembly of the present embodiment includes a fixing frame, one end of which is disposed within the accommodating space and the other end of which is exposed to the first housing through the clearance opening;

[0029] a first heating tooth, the first heating tooth being arranged on a side of the fixing frame away from the second shell;

[0030] The third comb structure has one end disposed in the accommodating space and the other end passing through the fixing frame and exposed to the first housing. The second comb assembly is easy to assemble.

[0031] 5. In the embodiment of the present invention, the multiple rows of first heating teeth are arranged along the length direction of the fixing frame on a side of the fixing frame away from the second housing, and each row of first heating teeth has a second comb hole formed between each row of first heating teeth;

[0032] The third comb structure includes a third base disposed within the accommodating space and second heating teeth connected to the third base. The second heating teeth extend away from the third base and are exposed to the first housing through second comb holes. Both the first and second heating teeth can transfer heat to facilitate hair straightening.

[0033] 6. In this embodiment of the utility model, a snap-in slot is defined on the side of the first comb assembly proximate to the second housing, and a protrusion is provided on the side of the mounting bracket proximate to the second housing. The protrusion cooperates with the snap-in slot to achieve a removable connection between the first and second comb assemblies. The protrusion cooperates with the snap-in slot, preventing the mounting bracket from fully passing through the clearance opening, thereby achieving a simple and convenient removable connection between the first and second comb assemblies.

[0034] 7. The second heating teeth of the present embodiment include a tooth post and a tooth ball. One end of the tooth post is connected to the third base, and the other end passes through the second comb hole and connects to the tooth ball. Both the tooth post and the tooth ball can come into contact with the hair to straighten the hair.

[0035] 8. The first heating teeth of this embodiment of the present invention include a first contact surface perpendicular to the length of the fixing frame and a second contact surface perpendicular to the width of the fixing frame. Both the first and second contact surfaces are rectangular, with the first contact surface being wider than the second contact surface. Increasing the area of ​​the first contact surface increases the contact area between the straightening comb and the hair, thereby improving the straightening effect when heated.

[0036] 9. The hair straightening comb of this embodiment also includes a heater plate, which is disposed within the accommodating space. The heater plate is in contact with the heater plate on the side of the second comb assembly adjacent to the second housing. The heater plate primarily provides heat and transfers it to the second comb assembly.

[0037] 10. In this embodiment, a button is provided on one end of the first housing, away from the second comb assembly. A control circuit board, electrically connected to the heater, is housed within the housing. The button is electrically connected to the control circuit board to control the heater. The control circuit board sends signals to control whether the heater is operating, making it simple and convenient.

[0059] In modern society, people are paying more and more attention to managing their hair. Traditional combs can only smooth hair, but cannot straighten it. Therefore, straightening combs have emerged. Straightening combs usually have a built-in heating module that heats the comb teeth. When the heated comb teeth come into contact with the hair, they can change the hair's protein structure and straighten the hair.

[0060] Existing hair straightening combs typically have multiple comb tooth assemblies, and these are generally not designed with modularity in mind. Each comb tooth assembly must be assembled separately during assembly. This lack of modularity requires extremely high assembly precision, making assembly of the comb tooth assemblies difficult.

[0061] Please combine Figure 1 、 Figure 2 and Figure 5 The first embodiment of the present invention provides a hair straightening comb 10. The hair straightening comb 10 includes a first housing 1 and a second housing 2 that are detachably connected. The first housing 1 and the second housing 2 form a storage space. It should be understood that the storage space can accommodate electronic components. The detachable connection between the first and second housings 1 and 2 facilitates the installation of the electronic components within the storage space. The first housing 1 defines a clearance opening 11 and a first comb tooth hole 12.

[0062] Furthermore, the hair straightening comb 10 further includes a first comb tooth assembly 3, which includes a first comb tooth structure 31 and a second comb tooth structure 32. One end of the first comb tooth structure 31 and the second comb tooth structure 32 is accommodated in the accommodating space, and the other end is a comb-shaped structure, which passes through the first comb tooth hole 12 and is exposed to the first shell 1;

[0063] The second comb assembly 4 has one end accommodated in the space and detachably connected to the first comb assembly 3 , and the other end passes through the clearance opening 11 and is exposed to the first housing 1 .

[0064] It can be understood that the clearance opening 11 is an opening with a larger area, and the second comb tooth assembly 4 can be partially exposed to the outside of the first shell 1 through the clearance opening 11, while the first comb tooth hole 12 is a plurality of small holes with smaller areas, and the comb-like structure of the first comb tooth assembly 3 can be exposed to the outside of the first shell 1 through the first comb tooth hole 12, for contacting the human hair when combing the hair.

[0065] It should be understood that both the first comb tooth assembly 3 and the second comb tooth assembly 4 can be used for combing hair. In this embodiment, the first comb tooth assembly 3 includes two modules, the first comb tooth structure 31 and the second comb tooth structure 32. Therefore, when the first comb tooth assembly 3 is installed on the first housing 1, the first comb tooth structure 31 and the second comb tooth structure 32 can be installed on the first housing 1 in sequence. In this case, there may be an adjustable gap between the first comb tooth structure 31 and the second comb tooth structure 32, so that the assembly accuracy of the first comb tooth structure 31 and the second comb tooth structure 32 does not need to be too high, reducing the difficulty of assembly. If the first comb tooth structure 31 and the second comb tooth structure 32 are made into an integrated structure, in order to allow the comb structure on the first comb tooth assembly 3 to accurately pass through the first comb tooth hole 12, the manufacturing process requirements for the first comb tooth structure 31 and the second comb tooth structure 32 are very high. Otherwise, due to the precision error of the first comb tooth structure 31 and the second comb tooth structure 32, they will not be able to be assembled. However, the bend at the connection between the first comb tooth structure 31 and the second comb tooth structure 32 will deform during cooling and forming, which will cause the integrated structure to be unable to be assembled on the first housing 1. Therefore, in this embodiment, the first comb tooth structure 31 and the second comb tooth structure 32 are made into two modules. The modular design allows them to adapt to their corresponding first comb tooth holes 12 during the assembly process, thereby reducing the difficulty of assembly.

[0066] For example, during assembly, the first and second comb tooth structures 31, 32 are first placed within the accommodating space. At this point, one end of the comb-shaped structure on each of the first and second comb tooth structures 31, 32 passes through the first comb tooth holes 12 and is exposed to the first housing 1, while the other end is unable to pass through the first comb tooth holes 12 and is retained within the accommodating space. Furthermore, the second comb tooth assembly 4 is placed within the accommodating space, with one end passing through the clearance opening 11 and exposed to the first housing 1, while the other end is unable to pass through the clearance opening 11 and is engaged with the first comb tooth assembly 3. The second housing 2 is then connected to the first housing 1, completing the assembly of the hair straightening comb 10. This provides low assembly difficulty and high efficiency.

[0067] Specifically, when the straightening comb 10 is assembled, the first comb assembly 3 is sandwiched between the second comb assembly 4 and the first housing 1. Furthermore, the first housing 1 includes a comb head 13 and a comb handle 14, which are connected to each other. The comb head 13 primarily contacts the hair, while the comb handle 14 is primarily intended for handholding. A clearance opening 11 is located in the center of the comb head 13, and the first comb tooth holes 12 are distributed around the periphery of the comb head 13, avoiding the clearance opening 11.

[0068] Furthermore, please combine Figure 5 and Figure 6 The first comb tooth structure 31 includes a first base 311 and a first comb tooth 312 connected to the first base 311, and the second comb tooth structure 32 includes a second base 321 and a second comb tooth 322 connected to the second base 321. The first base 311 and the second base 321 are both arranged in the accommodating space, and the end of the first comb tooth 312 away from the first base 311 and the end of the second comb tooth 322 away from the second base 321 can both pass through the corresponding first comb tooth hole 12 and be exposed to the first shell 1.

[0069] It should be understood that the first and second comb teeth 312, 322 are comb-like structures designed to contact hair and smooth it during combing. In this embodiment, since the first and second comb tooth structures 31, 32 are two modules, during assembly, the first comb tooth structure 31 can be assembled first and then the second comb tooth structure 32, or the second comb tooth structure 32 can be assembled first and then the first comb tooth structure 31, or the first and second comb tooth structures 31, 32 can be assembled simultaneously to the first housing 1. Upon completion of assembly, the first base 311 can be in close contact with the second base 321, or an adjustable gap can be left between the first and second bases 311, 321. When the first and second comb teeth 312, 322 are exposed to the first housing 1 through the corresponding first comb tooth holes 12, the first comb tooth holes 12 on the first housing 1 also act as a retaining force for the entire first and second comb tooth structures 31, 32, enhancing the secure installation of the first and second comb tooth structures 31, 32.

[0070] Furthermore, a first comb tooth hole 12 is defined on a side of the comb head 13 away from the second housing 2 , and both the first comb teeth 312 and the second comb teeth 322 include long comb teeth and short comb teeth.

[0071] Please also refer to Figure 4 The first comb tooth holes 12 include a row of long comb tooth holes 121 and two rows of short comb tooth holes 122. The long comb tooth holes 121 are arranged along the outer periphery of the comb head 13, and the two rows of short comb tooth holes 122 are respectively arranged on both sides of the long comb tooth holes 121. The length L1 of the long comb teeth exposed to the comb head after passing through the long comb tooth holes 121 is greater than the length L2 of the short comb teeth exposed to the comb head after passing through the short comb tooth holes 122.

[0072] It should be understood that the long and short comb teeth have different functions. Human hair is generally divided into long, dense hair and shorter, loose hair interspersed within the dense long hair. Loose hair is usually closer to the scalp and can provide support for the long hair farther from the scalp, making the long hair more fluffy. When using the straightening comb 10 to comb hair, the length L1 of the long comb teeth is greater than the length L2 of the short comb teeth. Therefore, the long comb teeth can directly contact the scalp and comb the hair in contact with the scalp. The short comb teeth, on the other hand, cannot contact the scalp and are used to comb the hair farther from the scalp. It should be noted that this embodiment adopts a design of one row of long comb teeth and two rows of short comb teeth. The larger number of short comb teeth makes it easier to comb the hair farther from the scalp, making the hair appear smoother.

[0073] Furthermore, please combine Figure 2 and Figure 3 The straightening comb 10 also includes a heating plate 5, which is disposed within the accommodating space. The second comb assembly 4, located near the second housing 2, is in contact with the heating plate 5. It should be understood that the heating plate 5 primarily provides heat and transfers it to the second comb assembly 4. During combing, the second comb assembly 4 contacts the hair and transfers heat to it, altering its protein structure and thereby straightening the hair.

[0074] Specifically, a button is provided at one end of the first housing 1 away from the second comb assembly 4, and a control circuit board 6 electrically connected to the heating plate 5 is provided in the accommodating space. The button is electrically connected to the control circuit board 6 for controlling the heating plate 5. The circuit board 6 can be controlled by the button, and the control circuit board 6 sends a signal to control whether the heating plate 5 is working, which is simple and convenient.

[0075] Furthermore, please combine Figure 3 、 Figure 7 and Figure 8 The second comb assembly 4 includes a fixing frame 41 , one end of which is disposed in the accommodating space, and the other end of which passes through the opening 11 and is exposed to the first housing 1 ;

[0076] The first heating teeth 42 are arranged on a side of the fixing frame 41 away from the second housing 2;

[0077] The third comb-tooth structure 43 has one end disposed in the accommodating space, and the other end passes through the fixing frame 41 and is exposed to the first housing 1 .

[0078] It can be understood that when assembling the second comb tooth assembly 4, the fixing frame 41 is first placed in the accommodating space, and then one end of the fixing frame 41 is exposed to the first shell 1 through the clearance opening 11, and the other end can be engaged with the first comb tooth assembly 3 to be fixed in the accommodating space. The first heating teeth 42 are arranged on the side of the fixing frame 41 away from the second shell 2, so when the heating element contacts the fixing frame 41, the fixing frame 41 can transfer heat to the first heating teeth 42. Furthermore, when the fixing frame 41 is fixed, the third comb tooth structure 43 is placed in the accommodating space, with one end of the fixing frame 41 exposed to the first shell 1, and the other end cannot pass through the fixing frame 41 and is fixed in the accommodating space.

[0079] Specifically, multiple rows of first heating teeth 42 are arranged on the side of the fixing frame 41 away from the second shell 2 along the length direction of the fixing frame 41, and each row of first heating teeth 42 is provided with a second comb tooth hole 411 between another row of first heating teeth 42; the third comb tooth structure 43 includes a third base 431 arranged in the accommodating space and second heating teeth 432 connected to the third base 431, and the end of the second heating tooth 432 away from the third base 431 passes through the second comb tooth hole 411 and is exposed to the first shell 1.

[0080] As can be understood, one end of the second heating teeth 432 passes through the second comb-tooth holes 411 and is exposed on the first housing 1, while the other end is connected to the third base 431. Since the third base 431 cannot pass through the second comb-tooth holes 411, the third base 431 is fixed within the accommodating space. Specifically, when the heating plate 5 generates heat, the heat can be transferred to the third base 431 and then transferred to the second heating teeth 432 through the third base 431.

[0081] Specifically, a snap-in slot 33 is provided on a side of the first comb tooth assembly 3 proximate to the second housing 2, and a protrusion 44 is provided on a side of the fixing frame 41 proximate to the second housing 2. The protrusion 44 cooperates with the snap-in slot 33 to implement a detachable connection between the first comb tooth assembly 3 and the second comb tooth assembly 4. It should be understood that when the fixing frame 41 is assembled to the first comb tooth assembly 3, the fixed end is directly passed through the clearance opening 11, and the protrusion 44 can cooperate with the snap-in slot 33, resulting in the fixing frame 41 being unable to completely pass through the clearance opening 11, thereby implementing a detachable connection between the first comb tooth assembly 3 and the second comb tooth assembly 4, which is simple and convenient.

[0082] Specifically, the second heating teeth 432 include a tooth post 4321 and a tooth ball 4322. The tooth post 4321 is cylindrical, while the tooth ball 4322 is spherical. One end of the tooth post 4321 is connected to the third base 431, and the other end passes through the second comb hole 411 and connects to the tooth ball 4322. When the heating plate 5 generates heat, the heat is transferred to the third base 431, and then transferred from the third base 431 to the tooth post 4321, and then from the tooth post 4321 to the tooth ball 4322. Both the tooth post 4321 and the tooth ball 4322 can come into contact with the hair to straighten it.

[0083] Specifically, the first heating tooth 42 includes a first contact surface 421 perpendicular to the length direction of the fixing frame 41 and a second contact surface 422 perpendicular to the width direction of the fixing frame 41. The first contact surface 421 and the second contact surface 422 are both rectangular, and the width of the first contact surface 421 is greater than the width of the second contact surface 422.

[0084] Furthermore, in this embodiment, the length of the long comb teeth is greater than the length of the first heating teeth 42 and the second heating teeth 432 to prevent the heated first heating teeth and the second heating teeth from directly contacting the scalp.

[0085] It can be understood that the length of the first contact surface 421 and the length of the second contact surface 422 are equal to the length of the first heating tooth 42. That is, the length of the first contact surface 421 and the length of the second contact surface 422 are equal. Since the width of the first contact surface 421 is greater than the width of the second contact surface 422, the area of ​​the first contact surface 421 is greater than the area of ​​the second contact surface 422. When using the straightening comb 10 for combing hair, the first contact surface 421 primarily contacts the hair. Therefore, increasing the area of ​​the first contact surface 421 increases the contact area between the straightening comb 10 and the hair, thereby improving the hair straightening effect when heated.
