[0046] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.
[0047] The specific structure is as Figures 1 to 11 shown.
[0048] This embodiment provides a heat dissipation system for a hair removal device, the heat dissipation system comprising: a shell 1, an air guide structure 14 and a fan 2, a housing 1 being formed with a receiving cavity, the air guide structure 14 and the fan 2 being both arranged in the receiving cavity; the air guide structure 14 being formed with a first heat dissipation channel for installing a first heating element and a second heat dissipation channel for installing a second heating element 30; a first air inlet 3 and an air outlet 22 being provided on the shell 1, the fan 2 having a first air inlet 5 and a first air outlet 6, the first heat dissipation channel having a second air inlet 15 and a second air outlet 16, the second heat dissipation channel having a third air inlet 26 and a third air outlet 27, the first air inlet 5 being communicated with the first air inlet 3, the second air inlet 15 and the third air inlet 26 being both communicated with the first air outlet 6, the second air outlet 16 and the third air outlet 27 being both communicated with the air outlet 22.
[0049] In this embodiment, a first heating element is provided in the first heat dissipation channel, and a second heating element 30 is provided in the second heat dissipation channel. When the fan 2 is working, external air enters the first air inlet 5 through the first air inlet 3, and enters the second air inlet 15 and the third air inlet 26 through the first air outlet 6, thereby entering the first heat dissipation duct and the second heat dissipation duct to take away the heat of the first heating element and the second heating element 30, and is discharged through the second air outlet 16 and the third air outlet 27, and then discharged to the outside through the air outlet 22. The fan 2 dissipates heat from the first heating element and the second heating element 30 through the first heat dissipation channel and the second heat dissipation channel, respectively, thereby improving the heat dissipation effect and durability. At the same time, one fan 2 does not occupy too much space in the accommodating cavity of the housing 1, so that the hair removal device can be relatively small in size and easy to carry.
[0050] In this embodiment, the first heating element is a lamp of the hair removal device, and the second heating element 30 is a heat dissipation plate of the hair removal device.
[0051] In the optional technical solution of this embodiment, a second air inlet 4 is also provided on the shell 1, and the fan 2 can form a first airflow in the first heat dissipation channel. An air intake 9 is provided on the channel wall of the first heat dissipation channel; the first airflow draws external air from the second air inlet 4 into the first heat dissipation channel through the air intake 9 to form a second airflow.
[0052] In this embodiment, when the fan 2 is working, external air enters the first air inlet 5 from the first air inlet part 3, and enters the second air inlet 15 through the first air outlet 6, thereby entering the first heat dissipation duct to form a first airflow. Since the first airflow has a certain flow rate when flowing, a lower pressure is formed at the air suction port 9 when passing through the air suction port 9, and the external air can be sucked into the first heat dissipation channel from the second air inlet part 4 to form a second airflow. The first heating element is cooled by the first airflow and the second airflow, thereby improving the heat dissipation effect and durability of the first heating element. At the same time, the air volume is enhanced by only one fan 2, which does not occupy too much accommodating cavity space in the shell 1, so that the hair removal device can be relatively small in overall size and easy to carry.
[0053] In an optional technical solution of this embodiment, the channel wall of the first heat dissipation channel has a first air guide plate 7 and a second air guide plate 8. The first air guide plate 7 and the second air guide plate 8 may be arranged sequentially along the air guide direction, and a gap is provided between the first air guide plate 7 and the second air guide plate 8 to form an air suction port 9, that is, an end of the first air guide plate 7 facing the second air guide plate 8 and an end of the second air guide plate 8 facing the first air guide plate 7 are opposite and spaced apart. Alternatively, the first air guide plate 7 and the second air guide plate 8 may be integrally formed to form an air guide plate body, and the air suction port 9 is provided on the air guide plate body. Preferably, the first air guide plate 7 and the second air guide plate 8 are staggered to form an air suction port 9, that is, the first air guide plate 7 and the second air guide plate 8 are relatively staggered, and a gap is provided between the side of the first air guide plate 7 facing the second air guide plate 8 and the side of the second air guide plate 8 facing the first air guide plate 7. Alternatively, the adjacent ends of the first air guide plate 7 and the second air guide plate 8 may be flush or provided with a gap, as long as the first air flow can suck the external air from the second air inlet 4 into the first heat dissipation channel through the air suction port 9 and form the second air flow. At the same time, the second air guide plate 8 can also guide the second air flow to blow toward the first heating element or guide the first air flow to blow toward the first heating element, or the second air guide plate 8 can guide the first air flow and the second air flow to blow toward the first heating element. The first air guide plate 7 and the second air guide plate have a simple structure and can guide the first air flow and the second air flow to blow toward the first heating element, thereby improving the heat dissipation effect.
[0054] In the optional technical solution of this embodiment, the first air guide plate 7 is bent along the wind guiding direction to form the first air guide portion 10 and the second air guide portion 11, and the second air guide plate 8 is bent along the wind guiding direction to form the third air guide portion 12 and the fourth air guide portion 13; the first air guide portion 10 is arranged at the first air outlet 6, and the second air guide portion 11 and the third air guide portion 12 are staggered to form the air intake 9, the second air guide portion 11 is used to guide the first airflow to dissipate heat to the first heating element, and the fourth guide portion 13 is used to guide the second airflow to dissipate heat to the first heating element.
[0055] In this embodiment, the air guiding direction of the first air guide part 10 is the same as the blowing direction of the first air outlet 6. Since the second air guide part 11 is bent relative to the first air guide part 10, the second air guide part 11 guides the first airflow to blow toward the first heating element, and the second air guide part 11 and the third air guide part 12 are staggered to form the air suction port 9. The fourth guide part 13 guides the second airflow to dissipate heat from the first heating element. At the same time, the first air guide plate 7 and the second air guide plate 8 are both bent, with a simple structure and better coordination with the fan 2 and the first heating element. Not only is the structure more compact, the space utilization rate of the accommodating cavity is improved, the hair removal device as a whole can be smaller, and the heat dissipation effect is improved.
[0056] In an optional technical solution of this embodiment, the second air guide portion 11 is inclined toward the side away from the third air guide portion 12. This not only increases the air intake port 9, but also allows the air guiding direction of the second air guide portion 11 to be staggered with that of the fourth air guide portion 13, preventing the second air guide portion 11 from guiding the first airflow toward the fourth air guide portion 13 and causing turbulence, thereby improving the formation effect of the second airflow and simultaneously improving the heat dissipation effect of the first airflow on the first heating element. This embodiment is not limited to this, and the second air guide portion 11 can also be arc-shaped. The arc-shaped second air guide portion 11 not only has the above-mentioned effects, but the arc shape can further enhance the air guiding effect of the second air guide portion 11, thereby enhancing the heat dissipation effect.
[0057] In the optional technical solution of this embodiment, the air guide structure 14 includes a base 17 and a middle cover 18. The middle cover 18 is covered on the base 17, and a first heat dissipation channel is formed between the middle cover 18 and the base 17; a second air inlet 15 and a second air outlet 16 are opened on the side wall of the middle cover 18.
[0058] In this embodiment, the middle cover 18 and the base 17 are fastened to each other through a first snap-fit structure, which makes installation and disassembly convenient and convenient for setting the first heating element on the base 17. The side walls of the middle cover 18 and the side walls of the base 17 both have a first air guide plate 7 and a second air guide plate 8, and when the middle cover 18 is fastened to the base 17, the first air guide plate 7 and the second air guide plate 8 on the side walls of the middle cover 18 are correspondingly fastened to the first air guide plate 7 and the second air guide plate 8 on the side walls of the base 17. The second air inlet 15 and the second air outlet 16 are opened on the side walls of the middle cover 18, which does not damage the structure of the base 17 and is convenient to manufacture.
[0059] In an optional technical solution of this embodiment, the air guide structure 14 also includes an upper cover 28, which is covered on the middle cover 18 and forms a second heat dissipation channel between the upper cover 28 and the top wall of the middle cover 18; a third air inlet 26 and a third air outlet 27 are opened on the side wall of the upper cover 28.
[0060] In this embodiment, the upper cover 28 and the middle cover 18 are fastened to each other by a second snap-fit structure, which makes installation and disassembly convenient, and it is convenient to set the second heating element 30 on the middle cover 18. The second air inlet 15 and the second air outlet 16 are opened on the side wall of the upper cover 28. Preferably, a first notch and a second notch are opened on the side wall of the upper cover 28, and the second air inlet 15 and the second air outlet 16 are formed between the first notch and the second notch and the top wall of the middle cover 18. The structure is simple and easy to manufacture.
[0061] This embodiment is not limited thereto, and the air guide structure 14 may also include a heat dissipation pipe, and a second heat dissipation channel is formed in the heat dissipation pipe.
[0062] In the optional technical solution of this embodiment, the shell 1 includes an annular wall 19, a top cover 20 and a bottom cover 21, and the top cover 20 and the bottom cover 21 are respectively covered on two opposite sides of the annular wall 19; the first air inlet 3 is arranged on the top cover 20 or the bottom cover 21, and the second air inlet 4 and the air outlet 22 are both arranged on the annular wall 19.
[0063] In this embodiment, the base 17 is arranged on the annular wall 19, the air intake 9 corresponds to the second air inlet 4, and the second air outlet 16 corresponds to the air outlet 22, so that the first airflow and the second airflow can be discharged to the outside through the air outlet 22, thereby improving the heat dissipation effect. At the same time, the shell 1 has a simple and beautiful structure and is easy to install.
[0064] Preferably, the first air inlet 3 is disposed on the top wall of the top cover 20, and is located on the side of the top wall; the second air inlet 4 and the air outlet 22 are located on either side of the light outlet 29 of the annular wall 19. The first air inlet 3 is provided with a plurality of first vents 23 communicating with the accommodating cavity; the second air inlet 4 is provided with a plurality of second vents 24 communicating with the accommodating cavity; and the air outlet 22 is provided with a plurality of third vents 25 communicating with the accommodating cavity. This simple structure provides excellent air intake and exhaust, thereby enhancing heat dissipation. Furthermore, the first air inlet 3 is located on the side of the top wall of the top cover 20, preventing users from blocking the first vents 23 with their fingers during use.
[0065] It should be noted that, in this embodiment, the first air inlet 3, the second air inlet 4 and the air outlet 22 may also be configured as structures such as a ventilation net or a ventilation layer.
