Referring to fig. 1 to 8, a beauty instrument 100 according to an embodiment of the present invention will be described.

As shown in fig. 1, 2 and 4, the beauty instrument 100 according to the embodiment of the present invention includes a housing 1, a lighting unit 2, a translucent cold compress 3, a translucent heat insulation 4, and a cooling member 5.

A working chamber 101 is defined in the housing 1, and the working chamber 101 is formed with a mounting port 1011. The polishing assembly 2 is arranged in the working cavity 101, the polishing assembly 2 comprises a heat exchange member 21 and a light emitting member 22, a cavity 211 is defined in the heat exchange member 21, the cavity 211 is provided with a first light outlet 211a, the first light outlet 211a corresponds to the mounting hole 1011, and the refrigerating member 5 is arranged on one side of the heat exchange member 21 deviating from the first light outlet 211a and is used for transferring refrigerating capacity to the heat exchange member 21. The light-transmitting cold compress piece 3 is arranged at the mounting opening 1011, and the refrigerating piece 5 transmits cold energy to the light-transmitting cold compress piece 3 through the heat exchange piece 21 so as to cool the beauty part.

The light-transmitting heat-insulating member 4 is disposed in the cavity 211, the light-transmitting heat-insulating member 4 is disposed between the light-emitting member 22 and the light-transmitting cold compress member 3 at intervals, the cavity 211 is divided into an installation cavity 2111 and a heat-insulating cavity 2112 by the light-transmitting heat-insulating member 4, the first light outlet 211a is formed in the heat-insulating cavity 2112, and the light-transmitting heat-insulating member 4 is a light-transmitting member for transmitting light emitted by the light-emitting member 22 to the light-transmitting cold compress member 3. The refrigerating element 5 is disposed on a side of the heat exchanging element 21 away from the first light outlet 211a for transferring cold energy to the heat exchanging element 21. It will be understood that the cooling element 5, acting as a cold source, transmits cold to the transparent cold dressing 3 via the heat exchanging element 21,

the luminescent device 22 is arranged in the installation cavity 2111, the installation cavity 2111 is closer to the refrigerating device 5 than the heat insulation cavity 2112, namely the installation cavity 2111 and the heat insulation cavity 2112 are sequentially arranged in the direction from the refrigerating device 5 to the light-transmitting cold dressing 3, for example, the installation cavity 2111 is positioned between the refrigerating device 5 and the heat insulation cavity 2112, the distance between the luminescent device 22 and the refrigerating device 5 is smaller than the distance between the luminescent device 22 and the light-transmitting cold dressing 3, the refrigerating device 5 cools the luminescent device 22 in the installation cavity 2111 through the heat exchange device 21, and the heat insulation cavity 2112 is used for preventing heat generated by the work of the luminescent device 22 from being transferred to the light-transmitting cold dressing 3.

Therefore, in the laser depilation process, the cold energy of the refrigerating piece 5 is transmitted to the beauty part such as skin through the heat exchange piece 21 and the light-transmitting cold dressing 3, so that the pricking feeling of the beauty part is relieved, and meanwhile, as the light-emitting piece 22 is arranged in the installation cavity 2111 limited by the heat exchange piece 21, the cold energy of the refrigerating piece 5 can effectively cool the light-emitting piece 22, so that the heat transmitted from the light-emitting piece 22 to the light-transmitting cold dressing 3 is reduced.

Printing opacity heat-insulating part 4 can not only play the printing opacity effect but also can play thermal-insulated effect simultaneously, 4 intervals of printing opacity heat-insulating part set up between illuminating part 22 and printing opacity cold compress 3, make printing opacity heat-insulating part 4 not contact with printing opacity cold compress 3, guarantee that thermal-insulated chamber 2112 plays good thermal-insulated effect, avoid printing opacity heat-insulating part 4 to produce the influence to the temperature of printing opacity cold compress 3, thereby further reduce the heat of illuminating part 22 to the transmission opacity cold compress 3 transmission, avoid printing opacity cold compress 3 to transmit the cold volume to printing opacity heat-insulating part 4 simultaneously, make printing opacity cold compress 3 can keep lower temperature. Because illuminating part 22 is more close to refrigeration piece 5, the cold volume of refrigeration piece 5 is to the orientation transmission of printing opacity cold compress piece 3 again after the cooling of illuminating part 22, utilize the thermal-insulated piece of printing opacity 3 to the hindrance of the heat of illuminating part 22 to the transmission of printing opacity cold compress piece 3 simultaneously, reach cooling and thermal-insulated dual function, reduce the heat of illuminating part 22 work to the influence of printing opacity cold compress piece 3, make printing opacity cold compress piece 3 have better cold compress effect.

According to the beauty instrument 100 of the embodiment of the utility model, the light-transmitting heat-insulating member 4 is arranged in the cavity 211, the light-transmitting heat-insulating member 4 is arranged between the light-emitting member 22 and the light-transmitting cold compress member 3 at intervals, the refrigerating member 5 transmits cold energy to the heat exchanging member 21, so that the temperature of the light-emitting member 22 can be reduced, the light-transmitting cold compress member 3 is kept at a lower temperature under the cooperative action of the heat exchanging part 32 and the heat exchanging member 21 for heat transfer, and the cold compress effect of the light-transmitting cold compress member 3 is remarkably improved. Moreover, because illuminating part 22 is closer to refrigeration piece 5, the cold volume of refrigeration piece 5 is to the direction transmission of printing opacity cold compress 3 again after the cooling of illuminating part 22, utilize the hindrance of printing opacity thermal-insulated 4 heat to the transmission of printing opacity cold compress 3 of illuminating part 22 simultaneously, reach cooling and thermal-insulated dual function, reduce the heat of illuminating part 22 work to the influence of printing opacity cold compress 3, make printing opacity cold compress 3 have better cold compress effect.

In some embodiments, as shown in fig. 1, 4 and 5, the light-transmitting cold compress 3 is an integral component, and the light-transmitting cold compress 3 includes a light-transmitting portion 31 and a heat exchanging portion 32, the light-transmitting portion 31 is disposed opposite to the first light outlet 211a, the heat exchanging portion 32 is avoided from the first light outlet 211a, and the heat exchanging portion 32 and an end surface of the heat exchanging portion 21 at an end away from the cooling member 5 cooperate to transfer heat, so that the heat exchanging portion 32 and the first light outlet 211a are disposed in a staggered manner.

When the beauty instrument 100 is used, the light-transmitting cold compress 3 is used for contacting the skin of a user, the light-emitting member 22 is used for emitting intense pulsed light, the light emitted by the light-emitting member 22 passes through the first light-emitting port 211a and acts on the skin of the user through the light-transmitting portion 31 to achieve depilation, because the light-transmitting cold compress 3 is separately provided with the heat exchanging portion 32 avoiding the first light-emitting port 211a, and the structure of the heat exchanging portion 32 is not limited by the first light-emitting port 211a, on the premise that the light-emitting amount of the first light-emitting port 211a is not affected, the structure design of the heat exchanging portion 32 is flexible, so that the heat exchanging portion 32 and the mounting port 1011 can be assembled well, for example, a matching structure is arranged above the heat exchanging portion 32, the light-transmitting cold compress 3 can be reliably assembled with the mounting port 1011 through the matching structure of the heat exchanging portion 32, and the mounting performance is improved; meanwhile, the heat exchanging part 32 is matched with the heat exchanging part 21 reliably, for example, the heat exchanging part 32 can be contacted with the heat exchanging part 21 upwards through the first light emitting port 211a, so that the heat exchanging part 21 can play a certain supporting and limiting role for the heat exchanging part 21, the heat exchanging part 21 is beneficial to limiting the heat exchanging part 32 at the mounting port 1011, namely, the heat exchanging part 32 is limited through the heat exchanging part 21 and the mounting port 1011, when the light-transmitting cold compress part 3 contacts a beauty part (such as user skin), the light-transmitting cold compress part 3 is not easy to shift when being subjected to external force, and the light-transmitting cold compress part 3 is ensured to be stably mounted.

In addition, because printing opacity cold compress 3 is not whole all sets up with first light-emitting mouth 211a relatively, printing opacity portion 31 can be corresponding less that sets up, heat transfer portion 32 and the cooperation of heat transfer 21 such as heat transfer portion 21 and the contact of heat transfer 21, be convenient for make printing opacity cold compress 3 great with the heat transfer area of heat transfer 21, the thickness of printing opacity cold compress 3 can suitably attenuate, in order to promote the heat transfer efficiency of printing opacity cold compress 3 with heat transfer 21, be favorable to reducing the cooling time of printing opacity cold compress 3, make printing opacity cold compress 3 can rapid cooling, bring better ice compress effect.

It should be noted that "the light transmission portion 31 is disposed opposite to/corresponding to the first light outlet 211 a" may be understood that, on a reference plane perpendicular to a normal direction (for example, a vertical direction in fig. 4) of the first light outlet 211a, a projection profile of the first light outlet 211a on the reference plane is located in a projection of the light transmission portion 31 on the reference plane, so that all light rays of the first light outlet 211a are emitted through the light transmission portion 31. The phrase "the heat exchanging portion 32 avoids the first light outlet 211 a" can be understood that the projection of the heat exchanging portion 32 on the reference plane is located outside the projection contour of the first light outlet 211a on the reference plane, that is, the projections of the two are not overlapped, and the heat exchanging portion 32 does not affect the light outlet of the first light outlet 211 a.

For example, in the example of fig. 4, the light-transmitting portion 31 is a solid structure, in this case, the light-transmitting portion 31 and the heat exchanging portion 32 may be connected to form an integral solid structure, in this case, all light rays of the first light outlet 211a are emitted through the light-transmitting portion 31, in this case, a straight line parallel to the thickness direction of the light-transmitting cold compress 3 moves in parallel along the projection profile of the first light outlet 211a on the reference plane to form a reference cylindrical surface, the reference cylindrical surface may divide the light-transmitting cold compress 3 into the light-transmitting portion 31 and the heat exchanging portion 32, the light-transmitting portion 31 is located inside the reference cylindrical surface, and the heat exchanging portion 32 is located outside the reference cylindrical surface. Alternatively, the light-transmitting portion 31 may be formed as a through hole, that is, a through hole is formed in the light-transmitting cold dressing 3, the through hole penetrates through the light-transmitting cold dressing 3 along the thickness direction of the light-transmitting cold dressing 3, the through hole is the light-transmitting portion 31, at this time, the light-transmitting portion 31 may be defined by the heat exchanging portion 21, and all the light rays of the first light outlet 211a are directly emitted through the light-transmitting portion 31.

For example, as shown in fig. 4, the matching structure provided on the heat exchanging portion 32 may be a step 321, the step 321 is provided around the edge of the heat exchanging portion 32, the mounting hole 1011 is provided with a matching step 1016, and the step 321 and the matching step 1016 match with each other to realize the assembly of the heat exchanging portion 32 and the mounting hole 1011, so that the mounting reliability is improved, and the operation is simple and convenient. Wherein, the matching step 1016 can be supported at the bottom of the step 321, so that the width of the mounting opening 1011 is smaller than that of the light-transmitting cold compress 3, and the light-transmitting cold compress 3 is prevented from being separated from the housing 1 through the mounting opening 1011 in the working chamber 101.

Note that in the description of the present application, "width" is a width characterized in the left-right direction in fig. 1.

In some embodiments, as shown in fig. 1, the heat exchange member 21 includes two heat conduction portions 2101, the two heat conduction portions 2101 are disposed oppositely to define the chamber 211 together, one ends (e.g., upper ends in fig. 1) of the two heat conduction portions 2101 far away from the first light outlet 211a may be connected, one ends (e.g., lower ends in fig. 1) of the two heat conduction portions 2101 corresponding to the first light outlet 211a are disposed at intervals to define the first light outlet 211a together, and each heat conduction portion 2101 is in contact with the heat exchange portion 32 respectively, so that the cold energy of the heat conduction portions 2101 is directly transferred to the heat exchange portion 32, which is beneficial to reducing the cold energy transfer loss, and meanwhile, the heat transfer areas of the heat exchange member 21 and the heat exchange portion 32 may be increased, thereby improving the heat exchange efficiency, and the light-transmissive cold compress member 3 may be cooled more rapidly.

For example, in the example of fig. 1, the heat exchanging element 21 is configured in a U shape as a whole.

In some embodiments, the ratio s2 of the projected area of the light-transmitting portion 31 to the projected area of the heat exchanging portion 32 along the normal direction (e.g., the up-down direction in fig. 1 and 4) of the first light outlet 211a satisfies 0.5 ≦ s2 ≦ 5, so as to ensure that the heat exchanging portion 32 better receives the cold energy transferred by the heat exchanging element 21 and more uniformly transfers the cold energy to the light-transmitting portion 31. For example, s2 may be 0.5, or 1, or 2.3, or 4.8, or 5, etc.

For example, in the example of fig. 1 and 4, the outline of the light transmission portion 31 is the same as the outline of the first light outlet 211a, the heat exchanging portion 32 is disposed around the light transmission portion 31 for a full circle, so that the heat exchanging portion 32 is formed in an annular structure, the projection area of the heat exchanging portion 32 is the projection area of the annular structure along the normal direction of the first light outlet 211a, and two opposite sides of the heat exchanging portion 32 are respectively matched with the two heat conducting portions 2101 for heat transfer.

Alternatively, the length of the light transmitting portion 31 is equal to the length of the heat exchanging portion 32 in the front-rear direction, and the width of the light transmitting portion 31 is 20mm to 40mm in the left-right direction, the width of the heat exchanging portion 32 may be 4mm to 20mm, and further the width of the heat exchanging portion 32 may be 5mm to 15 mm.

Of course, the heat exchanging portion 32 may be disposed around the light transmitting portion 31 by less than a full circle; for example, the light-transmitting portion 31 is formed in a square structure, the heat exchanging portion 32 may include two heat exchanging sections, and the two heat exchanging sections may be respectively disposed at two opposite side edges of the light-transmitting portion 31, and at this time, along a normal direction of the first light-emitting port 211a, a projection area of the heat exchanging portion 32 is a sum of projection areas of the two heat exchanging sections.

In some embodiments, as shown in fig. 1 and 4, the cosmetic apparatus 100 further comprises a first support 6, the first support 6 comprising an inner support portion 61, at least a portion of the inner support portion 61 being disposed within the thermally insulated chamber 2112, and the at least a portion of the inner support portion 61 being supported between the light-transmissive thermally insulated member 4 and the light-transmissive cold dressing 3 such that the inner support portion 61, the light-transmissive thermally insulated member 4, and the light-transmissive cold dressing 3 collectively define a sealed cavity therebetween. Obviously, inner support portion 61 can play the supporting role, effectively guarantees that printing opacity heat insulating part 4 and printing opacity cold compress 3 are contactless each other, is convenient for guarantee to have suitable interval between printing opacity heat insulating part 4 and the printing opacity cold compress 3 through reasonable setting up inner support portion 61 simultaneously.

Wherein, the airtight cavity that restricts between inner support portion 61, printing opacity heat insulating part 4 and the printing opacity portion 31, on one hand makes printing opacity heat insulating part 4 and printing opacity cold compress 3 have certain spacing distance to guarantee the thermal-insulated effect of thermal-insulated chamber 2112, on the other hand because the light of illuminating part 22 reaches printing opacity cold compress 3 through printing opacity heat insulating part 4, this airtight cavity can guarantee that its inside moisture is minimum, is difficult for taking place the condensation, avoids influencing the light conduction and takes place the electric leakage condition, with the normal work of cosmetic instrument 100 of effective assurance.

In some embodiments, as shown in fig. 1 and 4, the beauty instrument 100 further includes a first light reflecting member 7, the first light reflecting member 7 is disposed in the closed cavity, and the first light reflecting member 7 extends along the extending direction of the edge of the first light outlet 211a, when the light passes through the closed cavity and reaches the transparent cold compress 3, the first light reflecting member 7 can reflect the light and then converge the light at the first light outlet 211a, so as to reduce light loss and improve light energy utilization rate.

Alternatively, as shown in fig. 1, the first light reflecting member 7 is a closed ring-shaped light reflecting plate, and the first light reflecting member 7 may extend around the circumferential direction of the normal line of the first light outlet 211a so as to surround the inner wall surface of the closed cavity.

In some embodiments, as shown in fig. 4, the walls of the insulating cavity 2112 are spaced from the inner support section 61 to collectively define an insulating layer. That is to say, the inner frame portion 61 does not contact the heat exchange member 21, and since the heat exchange member 21 is used for transferring the cooling capacity of the cooling member 5 to the transparent cold compress member 3, the wall surface of the heat insulation cavity 2112 and the inner frame portion 61 are arranged at an interval, so that the cooling capacity of the heat exchange member 21 is greatly reduced or even no cooling capacity is transferred to the inner frame portion 61, and thus the cooling capacity absorbed by the heat exchange member 21 can be transferred to the transparent cold compress member 3 more, and the cold compress effect of the transparent cold compress member 3 is ensured.

Optionally, the heat insulation layer may be an air layer, and in this case, no other component may be additionally disposed between the wall surface of the heat insulation cavity 2112 and the inner support portion 61, which facilitates simplifying the structure of the beauty instrument 100; or the heat insulating layer may also be a heat insulating material, for example, the heat insulating layer is a mica sheet, that is, the heat insulating material is disposed between the wall surface of the heat insulating cavity 2112 and the inner bracket portion 61 to separate the inner bracket portion 61 from the wall surface of the heat insulating cavity 2112, so as to improve the heat insulating effect and further reduce the cold energy transferred from the heat exchanging element 21 to the inner bracket portion 61.

In some embodiments, as shown in fig. 4, a step portion 211b is disposed between the installation cavity 2111 and the thermal insulation cavity 2112, a side of the light-transmitting thermal insulation member 4 facing away from the light-transmitting cold compress member 3 abuts against the step portion 211b, and the step portion 211b can provide an installation position, so as to facilitate installation and positioning of the light-transmitting thermal insulation member 4 and ensure that the light-transmitting thermal insulation member 4 is not easily displaced in the cavity 211.

For example, in the example of fig. 1 and 4, the heat exchanging part 32 has a step 321, the step 321 is disposed around the edge of the heat exchanging part 32, the mounting opening 1011 is provided with a fitting step 1016, and the fitting step 1016 is supported at the bottom of the step 321 to prevent the light-transmissive cold compress 3 from falling out of the housing 1 through the mounting opening 1011; the part of the inner support part 61, which is located in the heat insulation cavity 2112, is supported between the light-transmitting heat insulation part 4 and the light-transmitting cold application part 3, because the housing 1 limits the downward movement of the light-transmitting cold application part 3, the light-transmitting cold application part 3 can limit the downward movement of the inner support part 61, the width of the installation cavity 2111 is smaller than that of the heat insulation cavity 2112, a step part 211b is defined between the installation cavity 2111 and the heat insulation cavity 2112, the upper end of the light-transmitting heat insulation part 4 is stopped against the step part 211b, the step part 211b can limit the upward movement of the inner support part 61 through the light-transmitting heat insulation part 4, and therefore stable installation of the light-transmitting cold application part 3, the light-transmitting heat insulation part 4 and the inner support part 61 is achieved.

In some embodiments, as shown in fig. 1 and 4, the cosmetic apparatus 100 further includes a second light reflecting member 8, and the second light reflecting member 8 is disposed in the installation cavity 2111, so that the second light reflecting member 8 can converge the light emitted from the light emitting member 22 at the light outlet of the installation cavity 2111, so that the light emitted from the light emitting member 22 is emitted to the light-transmissive heat-insulating member 4, thereby reducing light loss and improving light energy utilization efficiency; the second reflecting piece 8 is attached to the wall surface of the installation cavity 2111, so that the heat transfer effect between the heat exchange piece 21 and the second reflecting piece 8 is facilitated to be improved, and the cooling effect of the refrigerating piece 5 on the luminescent piece 22 is further improved.

Alternatively, as shown in fig. 1, the second reflector 8 is configured as an arc-shaped reflector which is arranged on the side of the lighting element 22 facing away from the light-transmitting thermal insulator 4.

In some embodiments, the heat insulation cavity 2112 has an light entrance region, the installation cavity 2111 has a second light exit region, light in the second light exit region is emitted to the light entrance region through the light-transmitting heat insulation member 4, and the width of the second light exit region is smaller than or equal to the width of the light entrance region. As shown in fig. 1, the upper opening of the heat insulation cavity 2112 forms a light entrance region, the lower opening of the installation cavity 2111 forms a second light exit region, and the width of the second light exit region is smaller than or equal to the width of the light entrance region, so that the light entrance region can completely receive light from the second light exit region, thereby preventing the wall surface of the heat insulation cavity 2112 from blocking light and ensuring the light exit amount of the light striking assembly 2.

For example, when the beauty instrument 100 includes the first support 6, the light incident area of the heat insulation cavity 2112 is correspondingly reduced, and the light incident area of the heat insulation cavity 2112 can be understood as an opening defined by the first support 6, for example, an upper side opening of the first support 6, and the width of the second light emitting area is smaller than or equal to the width of the opening defined by the first support 6, so as to prevent the first support 6 from blocking light from the second light emitting area.

When the beauty instrument 100 includes the first bracket 6 and the first light reflecting member 7, the light entrance area of the heat insulating cavity 2112 is further reduced, and the light entrance area of the heat insulating cavity 2112 can be understood as an opening defined by the first light reflecting member 7, for example, an upper opening of the first light reflecting member 7, and the width of the second light emitting area is smaller than or equal to the width of the opening defined by the first light reflecting member 7, so as to prevent the first light reflecting member 7 from blocking light from the second light emitting area.

When the beauty instrument 100 includes the second light reflecting member 8, the second light exiting region of the installation cavity 2111 is correspondingly reduced, and the second light exiting region of the installation cavity 2111 can be understood as an opening defined by the second light reflecting member 8, for example, an opening at the lower side of the second light reflecting member 8, and the width of the opening defined by the second light reflecting member 8 is smaller than or equal to the width of the light entering region, so as to ensure that the light entering region completely receives the light from the second light exiting region.

For example, in the example of fig. 1 and 4, the cosmetic apparatus 100 includes a first support 6, a first reflector 7, and a second reflector 8, the second reflector 8 defining an opening having a width less than or equal to the width of the opening defined by the first reflector 7.

In some embodiments, the spacing between the light transmissive insulating member 4 and the light transmissive cold compress 3 is greater than the spacing between the light transmissive insulating member 4 and the luminescent member 22. That is, the light-transmitting heat insulating member 4 is far from the light-transmitting cold dressing 3 relative to the light-emitting member 22, and the temperature of the light-transmitting heat insulating member 4 should be increased along with the light-emitting heat generated by the light-emitting member 22, so that the influence on the temperature of the light-transmitting cold dressing 3 can be reduced by the light-transmitting heat insulating member 4 being far from the light-transmitting cold dressing 3.

In some embodiments, the light transmissive thermal insulator 4 is a filter to screen out light of an appropriate wavelength.

Optionally, the thickness of printing opacity cold compress 3 is less than the interval between printing opacity heat insulating part 4 and the printing opacity cold compress 3, adopts this mode can make the thermal-insulated more abundant between printing opacity heat insulating part 4 and the printing opacity cold compress 3, and the thickness of printing opacity cold compress 3 is thinner, makes cold volume can transmit fast, is convenient for guarantee that whole printing opacity cold compress 3 temperature is comparatively balanced.

For example, the ratio s1 between the distance between the light-transmitting heat-insulating part 4 and the light-transmitting cold compress 3 and the thickness of the light-transmitting cold compress 3 satisfies that s1 is less than or equal to 10, so that the heat-conducting performance of the light-transmitting cold compress 3 is improved on the premise that the light-transmitting cold compress 3 is reliable in use, and the temperature of the light-transmitting cold compress 3 is further ensured to be uniformly distributed in the thickness direction of the light-transmitting cold compress 3. Alternatively, s1 may be 2, or 3.5, or 5.8, or 6, or 8.2, or 10, etc.

Optionally, the thickness of the light-transmitting cold compress part 3 is 1.5mm to 6mm (inclusive), for example, the thickness of the light-transmitting cold compress part 3 is 1.5mm, or 2mm, or 4.3mm, or 5mm, or 6mm, etc., the thickness of the light-transmitting cold compress part 3 is appropriate, and the light-transmitting cold compress part has good heat conduction efficiency, and cold energy can be rapidly transferred from the surface on one side of the thickness of the light-transmitting cold compress part 3 to the surface on the other side of the thickness of the light-transmitting cold compress part 3, so that the cold compress effect of the light-transmitting cold compress part 3 is improved; meanwhile, in the process that the light emitted by the lighting component 2 is emitted to the part of the human body to be beautified through the light-transmitting cold compress 3, the transmission loss of the light in the light-transmitting cold compress 3 is small, and the beautifying effect and the beautifying efficiency of the beautifying apparatus 100 are ensured conveniently. At this time, the distance between the light-transmitting heat insulating member 4 and the light-transmitting cold dressing 3 may be less than or equal to 15mm, for example, the distance between the light-transmitting heat insulating member 4 and the light-transmitting cold dressing 3 may be 14mm, or 12.5mm, or 1mm, or 8mm, etc.; of course, the distance between the translucent thermal insulation 4 and the translucent cold compress 3 may also be 20mm, or 25mm, or 30mm, etc.

In the example of fig. 4, the spacing between the light-transmissive thermal insulation 4 and the light-transmissive cold dressing 3 may be the distance between the lower surface of the light-transmissive thermal insulation 4 and the upper surface of the light-transmissive cold dressing 3.

Optionally, the light-transmissive cold compress 3 is a piece of sapphire material or a piece of glass (e.g., a piece of ordinary glass) in order to ensure the somatosensory effect of the user.

In some embodiments, the heat exchanging element 21 may be a ceramic element or a metallic copper element.

In some embodiments, as shown in fig. 4 and 5, the light emitting member 22 includes a light tube 221, two ends of the mounting cavity 2111 along the axial direction of the light tube 221 respectively penetrate through the heat exchanging member 21, and the light tube 221 is used for emitting intense pulsed light to provide a light source required for depilation. The beauty instrument 100 further comprises a second bracket 9, the second bracket 9 is arranged outside the installation cavity 2111, and the second bracket 9 is fixedly connected with both axial ends of the lamp tube 221 respectively, that is, the second bracket 9 is arranged outside the installation cavity 2111, the space of the installation cavity 2111 cannot be occupied, the light of the lamp tube 221 cannot be shielded, and the light loss is reduced, meanwhile, the design of the second bracket 9 is not limited by the installation cavity 2111 easily, and the second bracket 9 is also convenient to be connected with other components such as the housing 1.

The heat conductivity of the second support 9 is less than the heat conductivity of the heat exchanging element 21, so that the heat of the lamp 221 is not easily transferred to the outside through the second support 9, the lamp 221 is prevented from directly transferring the heat to the heat exchanging element 21, and the heat transferred from the lamp 221 to other parts through the second support 9 can be reduced.

Optionally, as shown in fig. 1, the beauty instrument 100 includes a first bracket 6, a portion of the first bracket 6 disposed in the heat insulation cavity 2112 is supported between the light-transmitting heat insulation member 4 and the light-transmitting cold compress member 3, and a second bracket 9 is connected to the first bracket 6, so that the bracket formed by the first bracket 6 and the second bracket 9 can achieve "one object is multi-purpose", to simplify the process, reduce the cost, and facilitate the compact structural design.

Alternatively, as shown in fig. 7, the second support 9 may be connected to the housing 1, and in this case, if the beauty instrument 100 includes the first support 6, the second support 9 and the first support 6 may be two supports independently provided, and the second support 9 and the first support 6 are assembled separately.

In some embodiments, as shown in fig. 1, 4 and 5, a heat dissipation air duct 102 is further defined in the housing 1, the housing 1 is formed with a first air inlet 1012 and a first air outlet 1015 which are communicated with the heat dissipation air duct 102, the cosmetic apparatus 100 further includes a partition 10 and a first heat dissipation fan 11, the partition 10 is disposed in the housing 1, and the partition 10 participates in the partition of the heat dissipation air duct 102 from the working chamber 101, so as to effectively prevent hot air in the heat dissipation air duct 102 from flowing into the working chamber 101 and affecting the cooling effect of the cooling member 5, and prevent the hot air in the heat dissipation air duct 102 from blowing the heat exchanging member 21, causing condensation, electric leakage, and the like; the first cooling fan 11 is disposed in the cooling air duct 102, the first cooling fan 11 and the refrigeration element 5 are disposed at an interval, and the first cooling fan 11 is used for driving the airflow in the cooling air duct 102 to flow.

When the beauty instrument 100 works, the first cooling fan 11 drives the airflow in the cooling air duct 102 to flow so that the air with lower temperature enters from the first air inlet 1012, and after the air flows directly or indirectly exchange heat with the refrigeration piece 5, the heat generated by the work of the refrigeration piece 5 can be taken away in time, and then the air with higher temperature is discharged from the first air outlet 1015, so that the heat dissipation of the hot end of the refrigeration piece 5 is realized.

It should be noted that "the partition 10 participates in the arrangement of separating the heat dissipation air duct 102 from the working chamber 101", may refer to the arrangement of separating the heat dissipation air duct 102 from the working chamber 101 only by using the partition 10, or may refer to the arrangement of separating the heat dissipation air duct 102 from the working chamber 101 by using the partition 10 and other components together. The term "the heat dissipation air duct 102 is separated from the working chamber 101" means that the partition 10 participates in completely separating the heat dissipation air duct 102 from the working chamber 101, at this time, the heat dissipation air duct 102 is not completely communicated with the working chamber 101, and there is no air flow circulation, so as to effectively isolate the heat transfer between the heat dissipation air duct 102 and the working chamber 101, and also means that the partition 10 participates in partially separating the heat dissipation air duct 102 from the working chamber 101, at this time, the heat dissipation air duct 102 is separated from the working chamber 101 at some positions, and is communicated at some positions, and it is only required to ensure that the hot air in the heat dissipation air duct 102 does not flow into the working chamber 101.

In some embodiments, as shown in fig. 1, the partition 10 and the cooling member 5 jointly separate the heat dissipation air duct 102 from the working chamber 101, so that the internal structure of the housing 1 can be fully utilized, the separation effect between the heat dissipation air duct 102 and the working chamber 101 is ensured, the hot air in the heat dissipation air duct 102 is more difficult to leap into the working chamber 101, and meanwhile, a separate structure is not required to be additionally provided, so that the number of components of the beauty instrument 100 can be reduced, the structure is simplified, and the cost is reduced.

Wherein, the separator 10 encircles the cold junction setting of refrigeration piece 5, then separator 10 is opening annular or seals annular part to separate refrigeration piece 5's cold junction and heat dissipation wind channel 102, separate refrigeration piece 5's hot junction and working chamber 101, the hot-air of separation heat dissipation wind channel 102 is to the cold junction heat transfer of refrigeration piece 5, thereby is convenient for guarantee refrigeration piece 5 cold junction to the heat transfer efficiency of piece 21 that trades, reduces the cold volume and leaks. Wherein the outer side edge of the partitioning member 10 can abut against the inner wall surface of the housing 1 to facilitate reliable mounting of the partitioning member 10.

It should be noted that the term "open ring" as used herein refers to: a ring shape with an opening (i.e. a non-closed ring shape), wherein "ring shape" is to be understood in a broad sense, i.e. not limited to "circular ring shape", e.g. also a "polygonal ring" or the like.

In some embodiments, as shown in fig. 1, 4 and 5, the beauty instrument 100 further includes a first heat sink 12, the first heat sink 12 is disposed in the heat dissipation air duct 102, and the first heat sink 12 includes a first heat sink 121, a second heat sink 122 and a first heat transfer connector 123, the first heat sink 121 and the second heat sink 122 are disposed at a distance, the first heat dissipation fan 11 is disposed between the first heat sink 121 and the second heat sink 122, the first heat sink 121 is disposed at an outlet side of the first heat dissipation fan 11, and the first heat sink 121 is matched with the hot end of the refrigeration element 5 for heat transfer, the second heat sink 122 is arranged at the inlet side of the first heat dissipation fan 11, and the second heat dissipation member 122 transfers heat with the airflow in the heat dissipation air duct 102, the first heat transfer connector 123 is connected between the first heat dissipation member 121 and the second heat dissipation member 122, so that the first heat dissipation member 121 and the second heat dissipation member 122 cooperatively transfer heat through the first heat transfer connector 123.

Thus, the first heat sink 12 is configured to include the first heat sink 121, the second heat sink 122 and the first heat transfer connector 123, the airflow in the heat dissipation air duct 102 can sequentially flow through the second heat sink 122, the first heat dissipation fan 11 and the first heat sink 121, so that the air flow in the heat dissipation air duct 102 can exchange heat with at least the first heat dissipation member 121 and the second heat dissipation member 122, thereby increasing the heat dissipation area, improving the heat dissipation efficiency, moreover, because the temperature of the inlet side of the first heat dissipation fan 11 is lower, and the temperature of the outlet side is higher, the first heat dissipation member 121 is matched with the hot end of the refrigeration member 5 to take away the heat at the hot end of the refrigeration member 5 in time, and is transferred to the second heat dissipating element 122, via the first heat transfer connector 123, to reduce the heat at the hot end of the refrigerant element 5, secondly, under the action of the first cooling fan 11, the heat of the refrigerating member 5 can be quickly discharged, so as to ensure the normal use of the beauty instrument 100.

Optionally, the first heat dissipation element 121 is an aluminum alloy element or a copper alloy element; the second heat dissipation element is a 122 aluminum alloy element or a copper alloy element.

Of course, the present application is not so limited; in some embodiments, as shown in fig. 6 and 7, the housing 1 has a first heat dissipation air duct 103, the first heat dissipation air duct 103 has a receiving cavity for receiving the cooling member 5, so that the cooling member 5 can be located in the first heat dissipation air duct 103, the lighting assembly 2 defines a second heat dissipation air duct 20a therein, the second heat dissipation air duct 20a extends along the axial direction of the light emitting member 22, and the second heat dissipation air duct 20a is communicated with the first heat dissipation air duct 103, the housing 1 is formed with a second air inlet 1013 and a second air outlet 1014, the second air inlet 1013 and the second air outlet 1014 are respectively communicated with the first heat dissipation air duct 103, and the cosmetic apparatus 100 further includes a second heat dissipation fan disposed in the first heat dissipation air duct 103, and the second heat dissipation fan is configured to drive an air flow in the first heat dissipation air duct 103.

Therefore, when the second heat dissipation fan operates, air flows from the second air inlet 1013 to the first heat dissipation air duct 103, and flows to the second heat dissipation air duct 20a through the first heat dissipation air duct 103 to dissipate heat of the polishing assembly 2, and finally, air flows out of the housing 1 through the second air outlet 1014, and then, by setting the second heat dissipation air duct 20a, the temperature of the polishing assembly 2 can be reduced, thereby prolonging the service life of the polishing assembly 2.

In some embodiments, as shown in fig. 7-9, the mounting cavity 2111 forms a second heat dissipation air channel 20a, and since the light emitting element 22 of the lighting assembly 2 is disposed in the mounting cavity 2111, the airflow flowing through the second heat dissipation air channel 20a can directly dissipate heat of the light emitting element 22, for example, the light emitting element 22 includes the lamp tube 221, so that the temperature of the lamp tube 221 can be reduced, and the lifetime of the lamp tube 221 can be prolonged.

Of course, the present application is not limited thereto; for example, the mounting cavity 2111 and the second heat dissipation air duct 20a may be separately disposed, and at this time, the airflow in the second heat dissipation air duct 20a does not flow through the mounting cavity 2111 to directly dissipate the heat of the light emitting element 22, so as to facilitate the realization of the diversified design of the beauty instrument 100.

In some embodiments, as shown in fig. 7-9, the first heat dissipation air duct 103 includes a first air duct 1031 and a second air duct 1032, the first air duct 1031 communicates with one end of the second heat dissipation air duct 20a, the second air inlet 1013 communicates with one end of the first air duct 1031 far away from the second heat dissipation air duct 20a, the second air duct 1032 communicates with the other end of the second heat dissipation air duct 20a, and the second air outlet 1014 communicates with one end of the second air duct 1032 far away from the second heat dissipation air duct 20a, so that the second heat dissipation air duct 20a communicates between the first air duct 1031 and the second air duct 1032.

For example, the accommodating cavity may be formed in the second air duct 1032, when heat dissipation is performed, the second heat dissipation fan is started to suck the air with lower temperature in the environment into the first air duct 1031 through the second air inlet 1013, the air flows to the second air duct 1032 through the second heat dissipation air duct 20a under the driving of the second heat dissipation fan, the air with lower temperature in the circulation process may exchange heat with the luminescent member 22, that is, dissipate heat of the luminescent member 22, and then the air continues to flow to the second air duct 1032, so that heat exchange may be performed on the hot end of the cooling member 5, and finally the hot air with higher temperature is discharged from the second air outlet 1014, thereby completing the whole heat dissipation process.

In the example of fig. 7, the fourth heat dissipation member 132 is provided in the second air passage 1032, a portion of the second heat transfer connector 133 is provided in the second air passage 1032, and another portion of the second heat transfer connector 133 cooperates with the first heat dissipation member 131 to transfer heat. The heat dissipation area of the second heat dissipation device 13 is large, which is convenient for improving the heat dissipation efficiency and improving the heat dissipation effect of the polishing assembly 2.

It should be noted that, in the description of the present application, the first feature and the second feature cooperate to transfer heat, which may mean that the first feature and the second feature directly cooperate to transfer heat or that the first feature and the second feature indirectly cooperate to transfer heat, and only heat transfer between the first feature and the second feature is required to be ensured. For example, a first feature may be in contact with a second feature when the first feature directly cooperates with the second feature to transfer heat.
