With further reference to fig. 1 and 7-12, another skin treatment device according to an embodiment of the present application is provided, including:

the housing assembly 10 comprises a housing 11 with a light outlet and a bracket 13 arranged in the housing 11, wherein the light outlet of the housing 11 is positioned at the opening 110, and a light source cavity 133 and a light transmission channel 1321 which communicates the light source cavity 133 with the light outlet of the housing 11 are formed in the bracket 13;

the light emitting component 20 comprises a first light source component 21 and a light transmitting piece 22, wherein the first light source component 21 is arranged in the light source cavity 133, the light transmitting piece 22 is arranged in the light transmitting channel 1321, and light generated by the first light source component 21 is emitted to the skin to be treated through the light transmitting piece 22;

For example, in the state shown in fig. 12, the fan assembly may be disposed below the reflective cover 211, and the first direction should be perpendicular to the light emitting direction X of the light emitting assembly 20 and downward.

The heat dissipation assembly 52 includes a heat dissipation bracket 521, the heat dissipation bracket 521 and the bracket 13 enclose to form a first ventilation flow channel, the first ventilation flow channel is communicated with the light source cavity 133 and the fan assembly 51, and extends gradually from the fan assembly 51 towards the light source cavity 133, at least part of the first ventilation flow channel is opposite to the first direction Z, so that along the light emitting direction X of the light emitting assembly 20, the first ventilation flow channel has a part gradually biased towards the light source cavity 133, so as to adapt to the bias of the fan assembly 51 relative to the light source cavity 133. The heat dissipation bracket 521 may be inserted into the inner surface of the housing 11 by a protrusion 524 toward the housing 11, thereby being relatively fixed to the housing 11. It is understood that the heat dissipation bracket 521 may be fixed relative to the housing 11 by other manners, such as abutting, a manner in which the limiting portion is matched with the limiting portion, a manner in which the clip is matched with the clip hole, and the like.

Because the heat dissipation support fixed on the support of the first light source component is utilized to enclose the support to form the first ventilation flow channel, two ends of the first ventilation flow channel are respectively in butt joint communication with the light source cavity and the fan component, the communication of the flow guide channel when the fan is biased relative to the light source cavity and the light tube is at different horizontal heights is realized, and the butt joint communication of the air channel of the light source cavity and the fan component can be completed only by installing the heat dissipation support on the support, so that the heat dissipation requirement of the skin treatment device can be well met. Meanwhile, the conventional heat dissipation support is directly matched with the fan and the support, the channel structural member is not required to be additionally arranged, two ends of the channel structural member are respectively aligned and fixed with the fan and the light source cavity, the number of parts is reduced, the assembling steps of the skin treatment device are simplified, and the assembling difficulty of the device can be reduced.

Specifically, when the heat dissipation bracket 521 is assembled to connect the first ventilation flow channel with the ventilation flow channel, the heat dissipation component 52 is only required to be mounted above the bracket 13 shown in fig. 12 (i.e. in the first direction Z forward direction), so that the heat dissipation bracket 521 and the bracket 13 enclose to form the first ventilation flow channel, and one side of the heat dissipation bracket 521 facing the fan component 51 is in butt joint connection with the air outlet of the fan component 51, so that the air outlet of the fan component 51 is connected with the light source cavity 133.

Here, the light emitting direction of the light emitting module 20 is a second direction, that is, a second direction X, as shown in fig. 12, the first direction Z faces upward, the second direction X faces rightward, and the light source cavity 133 is located at a side of the fan module 51 facing the light emitting direction X of the light emitting module 20. The heat dissipation bracket 521 is provided on a surface of the bracket 13 facing the first direction Z. Illustratively, the mounting face of the fan assembly 51 is offset toward the second direction X relative to the mounting face of the bracket 13 such that the mounting face of the fan assembly 51 is higher than the mounting face of the bracket 13.

In one embodiment, the bracket 13 includes a first bracket 131 and a second bracket 132 that are detachably connected, the second bracket 132 is located on a side of the first bracket 131 facing away from the fan assembly 51, the first bracket 131 and the second bracket 132 enclose a light source cavity 133, and a light transmission channel 1321 is formed inside the second bracket 132. The bracket 13 is further formed with a gas inlet 1311 and a gas outlet 1312 which are respectively communicated with the light source cavity 133, the gas inlet 1311, the light source cavity 133 and the gas outlet 1312 are sequentially communicated to form a gas flow channel, the gas inlet 1311 is arranged on one side of the light source cavity 133 facing the first direction Z, the first ventilation flow channel is communicated with the gas inlet 1311 and is in butt joint communication with the air outlet of the fan assembly 51, and the gas inlet 1311 and the gas outlet 1312 are respectively arranged at two ends of the light source cavity 133 in the gas flow direction. For example, the light source chamber 133 is elongated, the gas inlet 1311 and the gas outlet 1312 are respectively provided at both ends of the light source chamber 133 in the longitudinal direction, the low-temperature gas blown out from the air outlet of the blower assembly 51 enters the light source chamber 133 through the gas inlet 1311, and after heat generated in the light source chamber 133 is taken away, the heated gas flows out from the gas outlet 1312 and is then discharged out of the housing assembly 10.

As further shown in fig. 10 and fig. 13 to 14, in one embodiment, the heat dissipation bracket 521 includes a first baffle 5211, where the first baffle 5211 is covered on the gas inlet 1311 and forms a first ventilation channel with the first bracket 131. The first deflector 5211 and the first bracket 131 may be assembled by a fastening or fastening device.

Illustratively, the inner surface of the first baffle 5211 has a concave arc surface facing away from the gas inlet 1311, and the surface of the gas inlet 1311 facing the heat dissipation bracket 521 may also have an arcuate arc surface. Thus, along the light emitting direction X of the light emitting assembly 20, the surface of the first deflector 5211 facing the gas inlet 1311 gradually approaches the first bracket 131, and the surface of the gas inlet 1311 facing the heat dissipation bracket 521 gradually gets away from the heat dissipation bracket 521. That is, the more far from the air outlet direction of the fan assembly 51, the inner space of the first deflector 5211 is in a gradually reduced necking shape, the inner space of the gas inlet 1311 of the first bracket 131 is in a gradually enlarged flaring shape, and when the first deflector 5211 is covered on the first bracket 131, the first ventilation channel formed by combining the first deflector 5211 and the gas inlet 1311 is in a substantially uniform arc shape, so that the gas blown out from the air outlet of the fan assembly 51 has a relatively uniform and gentle flow. It will be appreciated that the inner surface of the first baffle 5211, the face of the gas inlet 1311 facing the heat sink bracket 521, may be beveled such that the first vent flow path is a sloped path connecting between the air outlet of the fan assembly 51 and the gas inlet 1311 of the first bracket 131.

After the air blown out from the air outlet of the fan assembly 51 passes through the arc-shaped first ventilation flow channel which is gradually biased towards the air inlet 1311 of the light source cavity 133, the air is introduced into the light source cavity 133 from the air inlet 1311, the air outlet and the air inlet 1311 of the intersected fan assembly 51 can be butted together through the first guide plate 5211 by the arc-shaped first ventilation flow channel, the butted communication between the fan assembly 51 and the light source cavity 133 at different horizontal heights is realized by utilizing the first guide plate 5211 of the heat dissipation bracket 521, the butted mode of the fan assembly 51 and the light source cavity 133 is not limited by the shape of the shell, the assembly is simple and convenient, and the assembly difficulty is reduced.

Specifically, as shown in fig. 11A to 11B and fig. 13, the first bracket 131 may further have a baffle 13111 protruding from the gas inlet 1311 and extending toward the first direction Z, the baffle 13111 at least partially surrounds the gas inlet 1311, and the baffle 13111 is respectively abutted with the first baffle 5211 and the air outlet of the fan assembly 51. Thus, when the first baffle 5211 is assembled with the first bracket 131, the baffle 13111 of the first bracket 131 is inserted into the first baffle 5211, so that the baffle 13111 can improve the splicing efficiency of the first baffle 5211 and ensure the butt joint effect of the first baffle and the second baffle at the splicing position.

In order to further ensure the abutting effect of the first bracket 131 and the first deflector 5211, the sidewall portion of the first deflector 5211 is recessed to form a second stepped portion 5211T, and the baffle 13111 is mounted on the second stepped portion 5211T such that the inner wall of the baffle 13111 is flush with the sidewall of the first deflector 5211.
