Moreover, when the user uses the hair clipper 1, the protection component 121 can prevent the user from directly contacting the heating component 122, so as to prevent the heating component 122 from scalding the user.

Referring to fig. 3, in order to accelerate the cooling of the hair salon 1, the hair salon 1 further includes a cooling device 111 disposed in the handle 11, an air passage 1211 is formed in the protecting assembly 121, an air outlet gap 123 is formed between the heating assembly 122 and the protecting assembly 121, and the handle 11 is communicated with the air passage 1211 and the air outlet gap 123. The cool air blown out by the cool air device 111 is discharged to the outside through the air passage 1211 and the air outlet gap 123. It can be understood that the protection component 121 can be cooled by the cold wind passing through the wind channel 1211, and the heating component 122 can be cooled by the cold wind passing through the wind outlet gap 123. By cooling the protection component 121 and the heating component 122 at the same time, the clamping component 12 can be cooled quickly and efficiently, and the hair styling efficiency of the hair styling device 1 is improved.

Referring to fig. 3, the protection assembly 121 further includes a protection housing 1212 and a protection bracket 1213, the protection bracket 1213 is disposed between the protection housing 1212 and the heating assembly 122, and the protection bracket 1213 and the protection housing 1212 define an air passage 1211. Specifically, the protective housing 1212 is a substantially arc-shaped housing and is fastened to the protective bracket 1213 to form a cavity, which is the air passage 1211. It can be understood that the wind in the wind passage 1211 can directly pass through the protective housing 1212 and the protective bracket 1213, and further can take away the heat of the protective housing 1212 and the protective bracket 1213 to the maximum extent, thereby achieving the quick and efficient cooling of the protective assembly 121.

Referring to fig. 3, a groove 12131 is further formed on a side of the protection bracket 1213 away from the protection housing 1212, and the heating element 122 is disposed in the groove 12131 and defines the air outlet gap 123 with the groove 12131. Specifically, the inner contour dimension of the groove 12131 is larger than the outer contour dimension of the heating element 122, and the heating element 122 disposed in the groove 12131 partially protrudes out of the opening of the groove 12131 and maintains a certain gap with the peripheral wall of the groove 12131, which is the air outlet gap 123. It will be appreciated that by locating the heating element 122 within the recess 12131, the structure between the heating element 122 and the guard element 121 can be made more compact, further reducing the overall size of the holder assembly 12 and making the hair clipper 1 more compact and aesthetically pleasing. Meanwhile, the air outlet gap 123 is defined by the heating assembly 122 and the groove 12131, and air in the air outlet gap 123 can directly pass through the heating assembly 122, so that heat on the heating assembly 122 can be taken away to the greatest extent, and the heating assembly 122 is cooled.

Referring to fig. 3 and 4, in order to achieve fast and efficient cooling of the heating element 122 and the protection element 121, the protection bracket 1213 is further provided with an air guiding channel 12132. The air guide channel 12132 is connected to the air outlet gap 123 through the air channel 1211, and the air guide channel 12132 divides the air flowing through the air channel 1211 and flows into the air outlet gap 123.

Specifically, the air passage 1211 is further provided with an air inlet 12111 corresponding to the cold air device 111, the air guiding passage 12132 is disposed at a side close to the air inlet 12111, the cold air blown from the cold air device 111 enters the air passage 1211 through the air inlet 12111, and a part of the cold air entering the air passage 1211 is diverted to enter the air outlet gap 123 through the air guiding passage 12132. Of course, the protective bracket 1213 may not be provided with the air guiding passage 12132, and as another embodiment, the air passing passage 1211 and the air outlet gap 123 are respectively provided with air inlets corresponding to the cold air device 111, and the cold air blown from the cold air device 111 flows into the air passing passage 1211 and the air outlet gap 123 through the two air inlets respectively.

Furthermore, in order to make the wind in the air passage 1211 flow into the air outlet gap 123 more smoothly, the protective bracket 1213 is further provided with an air guide 12133 for assisting the flow diversion. Specifically, a wind guide opening 12134 is formed in one side of the wind guide channel 12132 close to the air passage 1211, the wind guide member 12133 is substantially plate-shaped, one end of the wind guide member 12134 is arranged at an edge of the wind guide opening 12134, the other end of the wind guide member 12133 is inclined in a direction opposite to the ventilation direction of the air passage 1211, and a vertical projection of the wind guide member 12133 and a vertical projection of the wind guide opening 12134 are at least partially overlapped. It is understood that the wind entering the air passage 1211 from the wind inlet 12111 flows in a direction away from the wind inlet 12111, as shown by an arrow in fig. 4, since the air guide 12133 is inclined in a direction opposite to the ventilation direction of the air passage 1211, when the cold wind flows through the air guide 12133, the wind is blocked by the air guide 12133 and the flow direction is changed, and the wind with the changed flow direction can enter the wind outlet gap 123 through the air outlet 12134. Therefore, the air guide 12133 can better guide the cold air.

Referring to fig. 4 and 5, in order to accelerate the air in the air passage 1211 to be exhausted outside, the protective housing 1212 further has a plurality of rows of air outlets 12121, and the plurality of rows of air outlets 12121 are disposed corresponding to the air passage 1211.

Specifically, the air outlet 12121 is a through hole formed in the protective housing 1212, the air passage 1211 can be communicated with the outside through the air outlet 12121, the air in the air passage 1211 is discharged to the outside through the air outlet 12121, and the heat generated by the protective housing 1212 and the protective support 1213 can be taken away by the discharged air, so that the cooling of the protective housing 1212 and the protective support 1213 is accelerated.

The shape of the air outlet 12121 is not particularly limited in the embodiments of the present invention, and the air outlet 12121 may be a circular through hole, the air outlet 12121 may be a square through hole, or the air outlet 12121 may be a kidney-shaped through hole. Specifically, the air outlets 12121 in the embodiments of the present invention are waist-shaped through holes, and the waist-shaped direction of the through holes is the same as the length direction of the protective shell 1212, so that more air outlets 12121 can be disposed without affecting the strength of the protective shell 1212.

The number of the air outlets 12121 in the embodiment of the present invention is not specifically limited, and any number of the air outlets 12121 may be arranged in parallel in the length direction of the protective shell 1212, or may be arranged at a certain deflection angle with the length direction of the protective shell 1212.

Further, the air outlets 12121 of adjacent rows are staggered so as not to affect the strength of the protective shell 1212. It can be understood that, since the air outlets 12121 are through holes disposed on the protective shell 1212, if the air outlets 12121 are disposed at a certain position of the protective shell 1212 in a concentrated manner, the through holes are concentrated, and the structural strength of the protective shell 1212 is greatly reduced due to the concentrated through holes. The staggered air outlets 12121 are uniformly distributed on the protective shell 1212, so that the protective shell 1212 has good structural strength.

Referring to fig. 5 and 6, further, the protective shell 1212 is further provided with lightening holes 12122, and the lightening holes 12122 are disposed at a side close to the heating element 122.

Specifically, the lightening holes 12122 are kidney-shaped through holes provided on the shield shell 1212, which extend in the length direction of the shield shell 1212. It is understood that the weight-reduction holes 12122 provided in the protective case 1212 reduce the weight of the protective case 1212, thereby making the hairdresser 1 lighter overall and making the lighter-weight hairdresser 1 easier for the user to handle. Meanwhile, the overall volume of the protective shell 1212 can be reduced by providing the lightening holes 12122, and the protective shell 1212 with a smaller volume stores less heat, which is more beneficial to cooling the protective shell 1212. And the lightening holes 12122 are arranged at one side close to the heating assembly 122, when the heating assembly 122 heats the hair, the heat transferred from the heating assembly 122 to the protective shell 1212 can be reduced through the lightening holes 12122, thereby avoiding the heat loss of the heating assembly 122 and ensuring that the heating assembly 122 achieves the best heating effect.

The size of the lightening holes 12122 is not particularly limited in the embodiments of the present invention, and the size of the lightening holes 12122 may be set according to actual requirements. Specifically, to ensure optimal heating of the heating assembly 122, the lightening holes 12122 have a length greater than half the length of the protective shell 1212. Preferably, the lightening holes 12122 are of equal length to the length of the heater assembly 122 and correspond to the location of the heater assembly 122.

Referring to fig. 6, further, the two clamping members 12 further include opposite limiting protrusions 124, and when the two clamping members 12 are closed, the two limiting protrusions 124 abut against each other to maintain a gap (as shown by T in fig. 6) between the two clamping members 12. It can be understood that the two clamping components 12 with a certain gap can reduce the clamping force on the hair when the two clamping components 12 are closed, so that the hair can smoothly pass through the two clamping components 12, and further, the damage to the hair caused by the overlarge clamping force is avoided.

The embodiment of the present invention does not specifically limit the size of the gap between the two clamping assemblies 12 when the two clamping assemblies 12 are closed. Specifically, the gap between the two clamping assemblies 12 according to the embodiment of the present invention is 0.04mm, 0.06mm, 0.08mm, 0.1mm, 0.12mm, or 0.14 mm. Preferably, the gap between the two clamping assemblies 12 is 0.08 mm.

The shape of the limiting protrusion 124 is not particularly limited in the embodiment of the present invention, and the limiting protrusion 124 may be a spherical protrusion, the limiting protrusion 124 may also be a cylindrical protrusion, and the limiting protrusion 124 may also be a combination of a spherical protrusion and a cylindrical protrusion. Specifically, the limiting protrusions 124 of the embodiment of the utility model are spherical protrusions, and when the two limiting protrusions 124 abut against each other, the spherical protrusions can reduce the contact area between the two limiting protrusions 124, so that hair can pass through the two clamping assemblies 12 smoothly, and the hair is prevented from being clamped between the two limiting protrusions 124.

In summary, the hair dresser 1 with the heat dissipation function according to the embodiment of the present invention can perform hair straightening and styling. When the hair is styled, the hair is firstly placed between the two opened clamping components 12, then the two clamping components 12 are closed, and the heating and softening of the hair are realized through the heating component 122. After the heating is completed, the control button 1113 controls the driving motor 1111 to rotate the fan 1112, the cold air blown out by the fan 1112 flows into the air passage 1211, and the cold air flowing into the air passage 1211 is split by the cooperation of the air passage 12132 and the air guide 12133, and partially enters the air outlet gap 123. The air in the air outlet gap 123 passes through the heating element 122 and is exhausted to the outside, so that the heating element 122 is cooled. The air in the air passage 1211 passes through the protective housing 1212 and the protective bracket 1213 and is exhausted to the outside through the air outlet 12121, thereby cooling the protective assembly 121. By cooling the protection component 121 and the heating component 122 at the same time, the clamping component 12 can be cooled quickly and efficiently, and the hair styling efficiency of the hair styling device 1 is improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit of the present invention are intended to be included within the scope of the present invention.
