For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0034] In one embodiment of the present invention, referring to Figure 1 to Figure 4 A hot air comb structure includes a handle 100, a fan 200, a control circuit board 300, a heating device 400 and a combing plate 500. The handle 100 is hollow in structure, one end of the handle 100 is provided with an air inlet 101, and the other end is provided with a mounting member 110, the mounting member 110 is provided with a cavity with an opening facing upward, and the cavity is connected to the inside of the handle 100; the combing plate 500 covers the mouth of the cavity, and the combing plate 500 is provided with a plurality of comb teeth 510 and a plurality of hot air ports 501 connected to the cavity. The fan 200 and the control circuit board 300 are arranged in the handle 100, the heating device 400 is arranged in the cavity, the heating device 400 and the fan 200 are electrically connected to the control circuit board 300, and the control circuit board 300 is connected to a power line; the handle 100 is provided with a control switch 102 for controlling the power on and off of the heating device 400 and the fan 200. In this embodiment, when straightening hair, the power cord is connected to the power supply, and the fan 200 and the heating device 400 are powered on by the control switch 102. The fan 200 forms airflow inside and outside the hot air comb structure. After the airflow is heated by the heating device 400, it is blown out from the hot air outlet 501. When straightening hair, the comb teeth 510 and the hot air heat the hair at the same time while combing the hair, so that the hair is fixed and straightened hair is achieved; therefore, the hair can be heated and straightened while combing the hair, which simplifies the operation and brings convenience to the user. In the process of straightening hair, when the hair is heated by the comb teeth 501, the hot air blows to the hair, which can also avoid the hair loss caused by excessive temperature of the comb teeth, thereby protecting the hair.

[0035] Furthermore, the control circuit board 300 is disposed at one end close to the air inlet 101, and the fan is disposed at one end away from the air inlet 101. In this embodiment, the heat generated by the heating device can be effectively prevented from being transferred to the control circuit board 300, thereby protecting the control circuit board 300.

[0036] Further, refer to Figure 3 and Figure 6 , a partition 113 is provided in the cavity to divide the cavity into a first cavity 111 and a second cavity 112. A plurality of blowing holes 114 are provided on the bottom wall of the cavity, and the heating device 400 is arranged in the second cavity 112. An airflow switching mechanism 600 is provided at one end of the handle 100 close to the fan 200, which is used to switch the first cavity 111 or the second cavity 112 to be connected with the interior of the handle 100. In this embodiment, a normal temperature airflow is blown out through the blowing holes 114 to cool the hair and achieve the effect of curling the hair. Specifically, the airflow switching mechanism 600 switches so that the first cavity 111 is connected with the interior of the handle, so that the airflow generated by the fan 200 will enter the first cavity 111 and be blown out from the blowing holes 114. When curling is required, the comb teeth 501 comb the hair, and at the same time, the hair is wrapped around the surface of the mounting member 110 and pulled in the direction of the hair ends. After the comb teeth 501 heat the hair, the fan 200 blows a normal temperature airflow on the heated hair to cool the hair, thereby achieving a given shape and curling effect. Therefore, the hot air comb of this embodiment can both straighten hair and curl hair, achieving multifunctional use.

[0037] Furthermore, a supporting step is provided inside the cavity, and the partition 113 is supported on the step.

[0038] Further, refer to Figure 3 , Figure 5 and Figure 6 , a plurality of supporting parts 115 extend from the partition 113, and the heating device 400 is supported on the supporting parts 115. In this embodiment, by providing a plurality of supporting parts 115 extending upward on the partition 113, the heating device 400 is supported on the supporting parts 115, which effectively prevents the heat generated by the heating device 400 from being transferred to the partition 113, thereby preventing the heat from being transferred to the first cavity 111, preventing the air blown from the blowing hole 114 from being hot air, and thereby preventing the problem of poor curling effect.

[0039] Further, refer to Figure 1 to Figure 6, the airflow switching mechanism 600 includes a knob 601, a shaft 602 and a baffle 603. A connection hole (not shown in the drawings) is provided on one side of the handle 100, and the knob 601 is rotatably mounted in the connection hole. The shaft 602 is provided on the inner side of the knob 601, and the free end of the shaft 601 is connected to the rotation of the handle 100. The baffle 603 is provided on the outer surface of the shaft 601. The knob 601 is turned to switch the baffle 603 to be located at the air inlet of the first cavity 111 or the air inlet of the second cavity 112. In this embodiment, when curling is required, the knob 601 is turned so that the baffle 603 is rotated to the mouth of the second cavity 112, so that the wind generated by the fan 200 enters the first cavity 111 and blows out from the blowing hole 114. When straightening is required, the baffle 603 is rotated to the mouth of the first cavity 111.

[0040] Furthermore, the knob 601, the rotating shaft 602 and the baffle 603 are integrally formed by injection molding.

[0041] Further, refer to Figure 4 and Figure 6 The bottom of the connecting hole is provided in a slot, a spring 604 is provided in the slot, a limiting portion 605 is extended upwards from the spring 604, two limiting slots 606 are provided on the knob 601, and when the baffle 603 is turned over to the air inlet of the first cavity 111 or the air inlet of the second cavity 112, the limiting portion 605 of the spring 604 is clamped in the corresponding limiting slot 606, thereby achieving the function of positioning the knob 601.

[0042] Furthermore, the outer surface of the mounting member 110 is provided with a plurality of wind grooves, each of which is provided with a plurality of blowing holes 114. In this embodiment, during the curling process, the air from the blowing holes 114 enters the wind grooves to cool the hair, thereby preventing the hair from blocking the blowing holes 114.

[0043] Further, refer to Figure 6 , the heating device 400 includes a heat-conducting mounting plate 410 and a PCT 420. The heat-conducting mounting plate 410 is arranged in the cavity, and a mounting groove is arranged in the heat-conducting mounting plate 410, and the PCT 420 is arranged in the mounting groove. In this embodiment, the PCT 420 is powered on to generate heat and transfer the heat to the heat-conducting mounting plate 410, and then the heat is transferred to the comb teeth 510 by the heat-conducting mounting plate 410, and the heat of the heat-conducting mounting plate 410 is blown out from the hot air outlet 501 by the fan 200. When straightening hair, not only can the hair be heated, but also the heat-conducting mounting plate 410 can be cooled to avoid excessive temperature and burns to the hair.

[0044] Further, refer to Figure 2 and Figure 6 The comb plate 500 includes a mounting ring 520, a heat insulating ring 530 and a metal heat conducting plate 540.

In this embodiment, when straightening hair or curling hair, the heat generated by the heating device 400 is transferred to the metal heat conductive plate 540 and the metal comb teeth. Therefore, when straightening hair or curling hair, the hair is heated and shaped by the metal comb teeth. When heating the hair, the scalp is protected by the heat insulating comb teeth 521 to prevent the metal heat conductive plate 540 from scalding the scalp. Specifically, the heat insulating comb teeth 521 on the mounting ring 520 are higher than the comb teeth on the metal heat conductive plate 540.

[0045] Further, referring to FIG. Figure 2 , Figure 4 and Figure 6 The comb plate 500 is also provided with a slide groove 541, in which a comb strip 542 is slidably arranged, and a plurality of second comb teeth 543 are distributed on the comb strip 542, and a barb 544 is arranged at the upper end of the second comb teeth 543; the handle 100 is provided with a push button 120 for pushing the comb strip 540 to slide, so that the second comb teeth 543 are misaligned with the comb teeth 510. In this embodiment, when the hot air comb is used to curl hair, when the heat-insulating comb teeth 521, the metal comb teeth and the second comb teeth 543 are combed, and the hair is rolled on the outer surface of the mounting member 110, the comb strip 540 is pushed to slide by pushing the button 120, so that the second comb teeth 543 are misaligned with the comb teeth 510; therefore, the barb 544 of the second comb teeth 543 hooks the hair, which can prevent the hair from falling off the comb teeth 510; and it is convenient to curl hair.

[0046] Further, the reference Figure 5 and Figure 6 The end of the comb strip 542 extending into the handle 100 is provided with a limit protrusion 545 protruding upward, and the limit protrusion 545 is provided with an inclined surface.
