DETAILED DESCRIPTION

[0025] Reference below Figure 1-Figure 5 A hair straightener 100 according to an embodiment of the present invention is described.

[0026] like Figure 1-Figure 5 As shown, a hair straightener 100 according to an embodiment of the present invention includes: a housing 10 , a heating component 20 , a heating comb component 30 , a switch 40 and an opening and closing mechanism 60 .

[0027] Specifically, the housing 10 has a housing cavity 103 and an opening 1011, the opening 1011 is connected to the housing cavity 103, the heating component 20 is disposed in the housing cavity 103, at least part of the heating comb assembly 30 extends into the housing cavity 103 through the opening 1011, the heating comb assembly 30 is connected to the heating component 20, one end of the heating comb assembly 30 is detachably connected to the inner wall of the housing 10, the switch member 40 is disposed on the housing 10, and the switch member 40 is located at the other end of the heating comb assembly 30, and the switch member 40 switches between a closed state and an open state. The opening and closing mechanism 60 is disposed on the inner wall of the housing 10, the opening and closing mechanism 60 is detachably connected to the heating comb assembly 30, and the opening and closing mechanism 60 switches between an unlocked state and a locked state.

[0028] Among them, when the switch part 40 is in the closed state, the opening and closing mechanism 60 switches to the locked state, and the two ends of the switch part 40 are respectively stopped against the inner wall of the shell 10 and the other end of the heating comb tooth assembly 30, and the opening and closing mechanism 60 is stopped against the heating comb tooth assembly 30 to fix the heating comb tooth assembly 30 at the opening 1011; when the switch part 40 is in the open state, the opening and closing mechanism 60 switches to the unlocked state, and the two ends of the switch part 40 are respectively separated from the inner wall of the shell 10 and the other end of the heating comb tooth assembly 30, and the opening and closing mechanism 60 is separated from the heating comb tooth assembly 30.

[0029] For example, in Figure 1-Figure 3 In the example, the thickness direction of the housing 10 (eg, Figure 2 An opening 1011 is formed on one side of the housing 10 in the left-right direction (eg, Figure 1 The heating comb assembly 30 extends into the opening 1011 and is connected to the heating component 20. The other end of the heating comb assembly 30 is located outside the housing 10, facilitating contact between the heating comb assembly 30 and the user's hair. The switch 40 and the opening and closing mechanism 60 can both be disposed between the heating comb assembly 30 and the end of the housing 10. The switch 40 and the opening and closing mechanism 60 can be arranged along the thickness direction of the housing 10. When the hair straightener 100 is in operation, the heating component 20 is energized and generates heat, which can be transferred to the heating comb assembly 30. The heating comb assembly 30 contacts the user's hair, and the heat can be transferred to the hair. By pulling the hair straightener 100, a straightening effect is achieved.

[0030] One end of the switch member 40 extends into the housing 10 in the thickness direction of the housing 10, while the other end of the switch member 40 is located outside the housing 10. The opening and closing mechanism 60 is entirely located within the accommodating cavity 103. When the switch member 40 is in the closed state, the surface of the switch member 40 facing away from the accommodating cavity 103 is flush with the surface of the housing 10 in the thickness direction of the housing 10. At this time, the portion of the switch member 40 extending into the housing 10 abuts against the inner sidewall of the housing 10 in the longitudinal direction and the heating comb assembly 30, respectively. The end of the heating comb assembly 30 facing away from the switch member 40 is connected to the inner wall of the housing 10. Simultaneously, the opening and closing mechanism 60 switches to a locked state, abutting against one surface of the heating comb assembly 30 in the thickness direction, thereby securely fixing the heating comb assembly 30 in the opening 1011 and allowing the user to use the hair straightener 100 normally.

[0031] When the heating comb tooth assembly 30 needs to be cleaned, the user can press the switch member 40 downward to switch the switch member 40 from the closed state to the open state, and the opening and closing mechanism 60 switches to the unlocked state. At this time, the stopping effect of the switch member 40 and the opening and closing mechanism 60 can be cancelled, that is, the switch member 40 and the opening and closing mechanism 60 are both separated from the heating comb tooth assembly 30, and the heating comb tooth assembly 30 can be shaken at the opening 1011, and then the connection between the heating comb tooth assembly 30 and the inner wall of the shell 10 is removed, and the heating comb tooth assembly 30 can be taken out. The user can clean the heating comb tooth assembly 30 to make the heating comb tooth assembly 30 have a better cleanliness.

[0032] According to the hair straightener 100 of the present invention, one end of the heating comb assembly 30 is detachably connected to the inner wall of the housing 10. When the switch 40 is in the closed state, the switch 40 and the opening and closing mechanism 60 both abut against the heating comb assembly 30, securing the heating comb assembly 30 at the opening 1011. When the switch 40 is in the open state, the switch 40 and the opening and closing mechanism 60 are both separated from the heating comb assembly 30, allowing the heating comb assembly 30 to be removed. Thus, the heating comb assembly 30 is detachable, allowing the user to clean the heating comb assembly 30 in a timely manner, ensuring the cleanliness of the heating comb assembly 30, thereby improving the user experience. At the same time, the switch 40 and the opening and closing mechanism 60 cooperate with each other to securely secure the heating comb assembly 30 at the opening 1011 during use.

[0033] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the opening and closing mechanism 60 includes a fixed bracket 601, a rotating shaft 602, and a spring member 603. The fixed bracket 601 is provided on the housing 10 and is located in the accommodating cavity 103. The fixed bracket 601 is detachably connected to the heating comb assembly 30. The rotating shaft 602 is provided through the fixed bracket 601, and the two ends of the rotating shaft 602 are respectively connected to the inner wall of the housing 10. The spring member 603 is sleeved on the rotating shaft 602. One end of the spring member 603 passes through the fixed bracket 601 and abuts against the anti-scalding comb teeth 301. The other end of the spring member 603 abuts against the fixed bracket 601. The spring member 603 switches between an unlocked state and a locked state.

[0034] Reference Figure 4 and Figure 5 A mounting hole is formed on the inner wall of the housing 10 , and a through hole is formed on one side of the fixing bracket 601 adjacent to the opening 1011 . During installation, the switch member 40 is in the open state, one end of the rotating shaft 602 is passed through the fixed bracket 601, and the spring member 603 is sleeved on the rotating shaft 602. At this time, the spring member 603 is located in the fixed bracket 601, and the position of the spring member 603 is adjusted so that one end of the spring member 603 passes through the through hole and stops against the heating comb tooth assembly 30; then the above-mentioned one end of the rotating shaft 602 is passed through the other side of the fixed bracket 601, so that the two ends of the rotating shaft 602 are located outside the fixed bracket 601 and connected to the mounting hole of the shell 10; finally, the switch member 40 is switched to the closed state, the switch member 40 pushes the heating comb tooth assembly 30, and the heating comb tooth assembly 30 pushes the spring member 603 to rotate, so that the two ends of the spring member 603 stop against the fixed bracket 601 and the heating comb tooth assembly 30 respectively, that is, the spring member 603 is switched to the locked state, and the switch member 40 stops against the heating comb tooth assembly 30. In this way, the heating comb tooth assembly 30 can be fixed at the opening 1011.

[0035] When cleaning the heating comb tooth assembly 30, the switch member 40 is switched to the open state, the switch member 40 is separated from the heating comb tooth assembly 30, and the restoring force of the spring member 603 pushes the heating comb tooth assembly 30, so that the heating comb tooth assembly 30 is separated from the spring member 603, that is, the spring member 603 is switched to the unlocked state, so that the heating comb tooth assembly 30 can be taken out.

[0036] Further, refer to Figures 1-4 , a matching groove 6011 is formed on one of the fixing bracket 601 and the heating comb tooth assembly 30, and a matching protrusion 3011 is provided on the other of the fixing bracket 601 and the heating comb tooth assembly 30, and the matching protrusion 3011 is adapted to the matching groove 6011. Figure 4 Alternatively, a matching groove 6011 is formed on the heating comb assembly 30, and a matching protrusion 3011 is provided on the fixing bracket 601 (not shown).

[0037] like Figure 1-Figure 3 As shown, the fixing bracket 601 is located on one side of the length direction of the heating comb assembly 30. Two mating grooves 6011 are formed on the fixing bracket 601. Two mating protrusions 3011 are provided on one side of the length direction of the heating comb assembly 30. The two mating protrusions 3011 respectively fit into the two mating grooves 6011 to achieve the connection between the heating comb assembly 30 and the fixing bracket 601. The fixing bracket 601 is located on the side of the heating comb assembly 30 away from the switch member 40 and is connected to the inner wall of the housing 10. The fixing bracket 601 and the housing 10 do not move relative to each other. When the switch member 40 is in the closed state, the heating comb assembly 30 is fixed to the opening 1011. When the switch member 40 is in the open state, the restoring force of the spring member 603 pushes the heating comb assembly 30 to separate the mating protrusions 3011 from the mating grooves 6011, so that the heating comb assembly 30 can be removed from the opening 1011, making it easier for the user to clean the heating comb assembly 30.

[0038] According to some specific embodiments of the present invention, the heating comb assembly 30 includes anti-scalding comb teeth 301 and heat-conducting comb teeth 305. The anti-scalding comb teeth 301 include an anti-scalding body 3012 and a plurality of anti-scalding teeth 3013. In the description of the present invention, the meaning of "plurality" is two or more. The plurality of anti-scalding teeth 3013 are all arranged in the thickness direction of the anti-scalding body 3012 (for example, Figure 2The heat-conducting comb 305 is provided on the other side of the anti-scald comb teeth 301 in the thickness direction, and comprises a heat-conducting body 3051 connected with the heat-generating component 20 and a plurality of heat-conducting teeth 3052 provided on the side of the heat-conducting body 3051 adjacent to the anti-scald comb 301, each of the heat-conducting teeth 3052 extending into the corresponding anti-scald tooth 3013.

[0039] Specifically, as shown in Figure 4 The anti-scald tooth 3013 comprises a first comb tooth 3014 capable of conducting heat and a second comb tooth 3015 which can be a normal comb tooth (not capable of conducting heat). The first comb teeth 3014 are arranged in a matrix on one side of the anti-scald body 3012 in the thickness direction, and the second comb teeth 3015 are located on the outer circumferential side of the first comb teeth 3014 and are spaced apart along the circumference of the anti-scald body 3012. The number of the heat-conducting teeth 3052 of the heat-conducting comb 305 is consistent with the number of the first comb teeth 3014, and the heat-conducting teeth 3052 are fitted into the corresponding first comb teeth 3014. At this time, the heat of the heat-generating component 20 can be transmitted to the heat-conducting body 3051, and the heat of the heat-conducting body 3051 is further transmitted to the first comb teeth 3014 through the heat-conducting teeth 3052, so that the first comb teeth 3014 are in contact with the user's hair to achieve the straightening effect.

[0040] The heat-conducting comb 305 is provided on the other side of the anti-scald comb teeth 301 in the thickness direction, and comprises a heat-conducting body 3051 connected with the heat-generating component 20 and a plurality of heat-conducting teeth 3052 provided on the side of the heat-conducting body 3051 adjacent to the anti-scald comb 301, each of the heat-conducting teeth 3052 extending into the corresponding anti-scald tooth 3013.

[0041] In addition, by arranging the second comb teeth 3015 on the outer circumferential side of the first comb teeth 3014, the first comb teeth 3014 can be spaced apart, and the second comb teeth 3015 can block the user from being injured by the first comb teeth 3014 with high temperature, thereby ensuring the safety of the straightener 100.

[0042] Optionally, the first comb teeth 3014 can be made of high-temperature-resistant materials, such as PA46 (polyhexanediamine, a new type of polyamide resin with high melting point and high crystallinity), PA66 (polyamide, commonly known as nylon, which is a general term for high polymers containing amide groups in the main chain of macromolecules). But not limited to this.

[0043] The thermal comb teeth 305 can be made of aluminum or an aluminum alloy with good thermal conductivity. The thermal comb teeth 305 can directly contact the heating element 20 to achieve heat conduction; alternatively, the thermal comb teeth 305 and the heating element 20 can be isolated by a component with good thermal conductivity. In other words, the heat generated by the heating element 20 when powered on can be transferred to the thermal comb teeth 305.

[0044] In some optional embodiments, a waterproof member (not shown) is provided between the outer wall of the heat-conducting comb teeth 305 and the inner wall of the opening 1011. This waterproof member can fill the gap between the outer wall of the heat-conducting comb teeth 305 and the inner wall of the opening 1011, preventing external liquid from entering the container, thereby preventing short circuits within the housing 10.

[0045] In some optional embodiments, a micro switch may be provided on the switch element 40 for power-off protection.

[0046] According to some specific embodiments of the present invention, the outer wall of the heat-conducting body 3051 is provided with a plurality of limiting protrusions 3053, which are spaced apart along the circumference of the heat-conducting body 3051, and each limiting protrusion 3053 extends in a direction away from the heat-conducting body 3051. When the switch 40 is in the closed state, each limiting protrusion 3053 abuts against the inner wall of the housing 10 in the thickness direction of the anti-scalding body 3012. For example, Figure 3 and Figure 4 In the example shown, there are four limiting protrusions 3053, one on each side of the heat-conducting body 3051 in the width direction, and two limiting protrusions 3053 on the same side are located at each end of the heat-conducting body 3051 in the length direction. The side surface of the heat-conducting body 3051 adjacent to the anti-scalding comb teeth 301 protrudes beyond the side surface of the limiting protrusions 3053 adjacent to the anti-scalding comb teeth 301. When the switch 40 is in the closed state, the limiting protrusions 3053 abut against the side wall of the opening 1011 provided in the housing 10, preventing the heat-conducting comb teeth 305 and the anti-scalding comb teeth 301 from dislodging from the opening 1011, thereby ensuring the stability of the position of the heating comb tooth assembly 30.

[0047] According to some embodiments of the present invention, Figure 3As shown, the heating assembly 20 includes a power supply 201, a circuit board 202, and a heating element 203. The circuit board 202 is connected to the power supply 201, and the heating element 203 is connected to the circuit board 202. The heating element 203 is located between the circuit board 202 and the heating comb assembly 30. The power supply 201 and the heating comb assembly 30 are spaced apart along the length of the housing 10. The anti-scalding combs 301, the heat-conducting combs 305, the heating element 203, and the circuit board 202 are stacked in sequence along the thickness of the housing 10, so that the circuit board 202 and the power supply 201 are spaced apart along the length of the housing 10. A power button 50 is provided on the housing 10 and is electrically connected to the circuit board 202. When the user uses the hair straightener 100, the power button 50 is pressed. After receiving the signal, the circuit board 202 causes the power supply 201 to supply power to the heating element 203. That is, the heating element 203 is energized and generates heat. The heat of the heating element 203 is transferred to the anti-scalding comb teeth 301 through the heat-conducting comb teeth 305. When the anti-scalding comb teeth 301 come into contact with the user's hair, the heat can be transferred to the hair, and then the hair straightener 100 is pulled to achieve a straightening effect.

[0048] The power supply 201 may be a battery pack, which may be equipped with an adapter and a charging cable, allowing the hair straightener 100 to be used while charging. Alternatively, the power supply 201 may be powered by mains electricity. The circuit board 202 may be a PCB (printed circuit board 202). The heating element 203 is not limited to PTC (Positive Temperature Coefficient, a semiconductor heating ceramic whose resistance decreases and its heat generation increases when the external temperature decreases), MCH (Metal Ceramics Heater, a ceramic heating element formed by printing a tungsten or molybdenum-manganese slurry onto a ceramic tape-cast body, laminating the layers through hot pressing, and then sintering the ceramic and metal together at 1600°C under a hydrogen atmosphere), graphene, thick film heating, and thin film heating technologies.

[0049] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the housing 10 includes a first housing 101 and a second housing 102. An opening 1011 is formed on the first housing 101. One side of the first housing 101 is open. The switch member 40 is provided on the first housing 101. The second housing 102 is detachably provided on the open side of the first housing 101. The second housing 102 and the first housing 101 together define a receiving chamber 103. Specifically, the first housing 101 and the second housing 102 are arranged along the thickness direction of the housing. The first housing 101 and the second housing 102 can be connected by fasteners such as screws or by engaging a buckle and a slot. The first housing 101 and the second housing 102 can protect the heating component 20 and the heat-conducting comb teeth 305, preventing damage to the hair straightener 100, so that the hair straightener 100 can operate normally.
