[0035] The utility model provides a hot air comb.

[0036] See also Figures 1 to 7In one embodiment of the utility model, the hot air comb includes a comb 100, a handle 200 and a hot air assembly 300. The comb 100 includes a shell 110 and an air guide cover 120. The shell 110 includes a first shell portion 111 and a second shell portion 112 that are spliced ​​together. That is, the first shell portion 111 and the second shell portion 112 can be detached from each other. The peripheral side of the shell 110 is convexly provided with comb teeth 113 and is provided with an outgoing air hole 116. The first shell portion 111 and the second shell portion 112 are detachable from each other. The first shell 111 and the second shell 112 enclose an installation cavity 117, the air guide cover 120 is arranged in the installation cavity 117, and a heating cavity 121 is provided. The hot air assembly 300 includes a heating element 310 at least partially arranged in the heating cavity 121. Therefore, when the first shell 111 and the second shell 112 can be detached from each other, the air guide cover 120 or the heating element 310 in the air guide cover 120 can be repaired and maintained by detaching the first shell 111 or the second shell 112; the air guide cover 1 The comb 200 includes an air guide inlet 122 and an air guide outlet 123 connected to the heating chamber 121, and the air guide outlet 123 is connected to the outgoing air hole 116 through the mounting chamber 117. The handle 200 is provided with a handle air inlet 210 connected to the air guide inlet 122. The hot air assembly 300 also includes a fan 320 arranged on the handle 200, and the air outlet side of the fan 320 is connected to the handle air inlet 210. That is, when most of the structure of the heating element 310 is arranged in the heating chamber 121, the fan 320 draws the external air flow into the handle 200 from the handle air inlet 210, and the air flow in the handle 200 flows to the air guide inlet 122 through the air outlet side of the fan 320, so that the air flow enters the heating chamber 121 and is heated by the heating element 310. Then, the heated air flow enters the mounting chamber 117 through the air guide outlet 123, and then flows to the outside through the outgoing air outlet, so as to heat the hair contacted by the comb 100 to achieve drying or styling. Among them, by arranging most of the structure of the heating element 310 in the installation cavity 117, the location where the heating airflow occurs is transferred from the handle 200 to the installation cavity 117, which helps to shorten the length of the handle 200 and is convenient for the user to hold and use. When the user holds the hot air comb, the user will not hold the installation cavity 117, so as to avoid the situation where the user cannot lift the hot air comb due to overheating of the handle 200 during use, thereby preventing the user from being scalded by the handle 200.

[0037] In one embodiment, the first shell 111 and the second shell 112 are detachably connected, and the second shell 112 is fixedly connected to the handle 200.

In other embodiments, the first shell 111 can also be fixedly connected to the handle 200.

[0038] In one embodiment, the outgoing air hole 116 is provided on the first shell 111. That is, the second shell 112 is not provided with an outgoing air outlet, so the hair in contact with the second shell 112 is not blown by the hot air, so when the hair is dried to a certain degree, or the hair styling reaches a certain stage, the user can use the comb teeth 113 on the second shell 112 to comb the hair, and observe the condition of the hair without cutting off the power supply of the hot air comb, so that the user can make an estimate for the next stage of drying or styling. In other embodiments, the outgoing air outlet can also be provided on the second shell 112; or the first shell 111 and the second shell 112 are provided with outgoing air outlets.

Specifically, the planar cross-sectional shape of the first comb tooth 114 is an elongated strip, and the end of the elongated strip away from the shell 110 has an outward convex arc surface, that is, the first comb tooth 114 is a columnar structure; the planar cross-sectional shape of the second comb tooth 115 is a triangle, that is, the second comb tooth 115 is firmly stressed in the circumferential direction of the shell 110. Since the hair moves circumferentially relative to the shell 110 when combing the hair, the second comb tooth 115 has a good hair clearance performance. The first comb teeth 114 are provided on the first shell 111, and the first comb teeth 114 are inserted into the first shell 111. The second comb teeth 115 are provided on the second shell 112 and are integrally formed with the second shell 112. The bottom edge of the second comb teeth 115 has a large contact area with the second shell 112, so the second comb teeth 115 can be stably formed on the second shell 112. In other embodiments, the planar cross-sectional shapes of the first comb teeth 113 and the second comb teeth 115 can be configured to be the same; and / or, the first comb teeth 114 are integrally formed with the first shell 111, and the second comb teeth 115 are integrally formed with the second shell 112. In another embodiment, the first comb teeth 114 are separately formed with the first shell 111, and the second comb teeth 115 are separately formed with the second shell 112.

[0040] In one embodiment, the housing 110 further includes a rotating housing 118, which is disposed between the first housing 111 and the second housing 112. The rotating housing 118 has a first position, a second position, and a third position arranged in sequence. The rotating housing 118 moves between the first position and the second position. In the first position, there is an air outlet gap between the rotating housing 118 and the first housing 111. In the second position, there is an air outlet gap between the rotating housing 118 and the second housing 112 and the first housing 111. In the third position, there is an air outlet gap between the rotating housing 118 and the second housing 112, and the air outlet gap is connected to the installation cavity 117. That is, the rotating housing 110 controls the position of the air outlet gap by rotating to control the drying position of the hot air. In other embodiments, the rotating housing 110 may not be provided.

[0041] In one embodiment, a plurality of air guide outlets 123 are provided, and at least one air guide outlet 123 is disposed relative to the rotating shell 118. This allows more airflow to flow out of the air outlet gap, effectively heating and drying the hair at the air outlet gap. In other embodiments, the air guide cover 120 may not be provided with an air guide outlet 123 at a position relative to the rotating shell 118.

[0042] In one embodiment, the air guide cover 120 is provided with a first convex rib 124 and a second convex rib 125, the first convex rib 124 and the second convex rib 125 are arranged close to the rotating shell 118, and the first convex rib 124 abuts against the first shell 111, and the second convex rib 125 abuts against the second shell 112, the air guide cover 120 and the rotating shell 118 enclose a wind cavity 126 through the first convex rib 124 and the second convex rib 125, and at least one air guide outlet 123 is arranged in the wind cavity 126. That is, the airflow flowing out of the air guide outlet 123 arranged relative to the rotating shell 118 will flow into the wind cavity 126, and there will be no situation where part of the airflow diffuses into the installation cavity 117, which is conducive to increasing the flow rate of the airflow gushing out from the air outlet gap. In other embodiments, the air guide cover 120 may not be provided with the first convex rib 124 and the second convex rib 125.

[0043] In one embodiment, two rotating shells 118 are provided, which are disposed on opposite sides of the second shell 112. In other embodiments, only one rotating shell 118 may be provided, which is disposed on one side of the second shell 112, and the other side of the second shell 112 is adjacent to the first shell 111.
