Description

TECHNICAL FIELD The present disclosure relates generally to the technical field of hair-removal devices, and more particularly to a hair-removal apparatus. BACKGROUND Hair-removal devices are comfortable, safe and fashionable household apparatuses that adopts advanced optical hair removal to effectively prevent the regrowth of hair on various parts of the body and remove hair permanently. A light-based hair removal device is disclosed in JP 3 226132 U, for instance. In the existing art, a heat-dissipating mechanism is usually provided inside the hair-removal device, therefore the heat dissipation performance thereof will directly affect the cold-compress effect and the durability of the hair-removal device. However, the heat dissipation performance of the heat-dissipating mechanism in traditional hair-removal devices is not good, which reduces the durability thereof. Although some hair-removal devices on the market are provided with an independent air-inlet channel, the air intake volume through a single air-inlet channel is difficult to meet the heat dissipation requirements of the internal mechanisms of the hair-removal device, and due to the structure of the heat-dissipating mechanism, the heat of the components inside the hair-removal device that need to be dissipated cannot be dissipated timely, leading to a low heat dissipation performance. To solve the problems above, it is urgent to provide a new type of hair-removal device. SUMMARY To solve the problems in the existing art that only one air-inlet channel is provided in traditional hair-removal devices, the air inlet volume of the air-inlet channel is limited and the heat dissipation efficiency is low, a hair-removal apparatus is provided. To solve the problems above, an embodiment of the present disclosure provides a hair-removal apparatus, which includes a housing, a main body accommodated in the housing, a first air-inlet channel and a second air-inlet channel. The main body includes a heat-generating assembly and a refrigerating assembly. The first air-inlet channel and the second air-inlet channel respectively communicate the refrigerating assembly and the heat-generating assembly with ambiance to absorb external air and dissipate heat thereof. The invention is defined in the appended set of the claim. Compared with the existing art, the hair-removal apparatus of the present disclosure has the following beneficial effects. The hair-removal apparatus includes two independent air-inlet channels constructed by disposing two independent air inlets on the fan housing to absorb external air and dissipate heat from the refrigerating assembly and the heat-generating assembly simultaneously, which solves the problem of inability to take the heat dissipation of multiple heating components simultaneously into account. Therefore the heat dissipation performance of the hair-removal apparatus is enhanced, and the durability and safety of the hair-removal apparatus are improved. A fast-flowing airflow is formed via the rotation of the fan in the fan housing, and the flowing airflow flows in via the first air-inlet channel and the second air-inlet channel respectively, such that the air volume entering the internal mechanism of the hair-removal apparatus per unit time is greatly increased. Powerful and sufficient airflow can take away the heat of the heat-generating assembly and the refrigerating assembly inside the hair-removal apparatus timely, and dissipate heat via the air-outlet hole on the second housing of the hair-removal apparatus, which further improves the heat dissipation performance of the hair-removal apparatus. Further, the first air-inlet channel and the second air-inlet channel are independent of each other. The airflow passing through the first air-inlet channel will take away the heat of the refrigerating assembly disposed to the first air inlet, which accelerates the refrigeration of the refrigerating assembly, such that the heat of the heat-conducting substrate and the refrigerating sheet connected to the refrigerating assembly can be dissipated timely, so as to improve the refrigeration efficiency of the refrigerating sheet. The icing effect of the hair-removal apparatus is better when in use, and the user experience is thus improved. In addition, external air sucked into the second air-inlet channel will pass through the heat-generating assembly and take away the heat of the heat-generating assembly and the heat-dissipating member, which accelerates the refrigeration of the heat-generating assembly and the heat-dissipating member. Understandably, the independent first air-inlet channel and the second air-inlet channel respectively dissipate heat via the flowing air flow in different portions of the hair-removal apparatus, such that the heat of each component inside the hair-removal apparatus can be promptly dissipated, which further improves the heat dissipation performance of the hair-removal apparatus, greatly improves the durability o
