The housing 40 also has a tail end opposite to the head portion 42.

The hand-held portion 41 is located between the head portion 42 and the tail end, so as to facilitate holding the depilator 100.

[0024] Optionally, the cold compressing surface 11 is a flat surface, and the heat conducting surface 12 is a flat surface. 3 CA 03183178 2022- 12- 16

[0025] Optionally, the cold compressing surface 11 is an end surface of the cold compressing portion 10.

The heat conducting surface 12 is a side surface of the cold compressing portion 10.

[0026] The first plate 33 and the second plate 34 arc both flat plates.

The heat conducting net 36 is laminated between the first plate 33 and the second plate 34.

The heat conducting net 36 is in full contact with the heat conducting medium 35, so that a contact area of the heat conducting medium 35 contacting the first plate 33, the second plate 34, and the heat conducting net 36 increases, and the heat conducting medium 35 can quickly absorb the heat that is absorbed by the main heat absorbing portion 31 from the cold compressing portion IO and quickly conducts the heat to the heat outputting portion 32.

[0027] Optionally, the cold compressing portion IO and the heat sink assembly 20 respectively contact two opposite surfaces of the heat conducting plate 30.

For example, the main heat absorbing portion 31 of the first plate 33 is in contact with the cold compressing portion l O; the heat outputting portion 32 of the second plate 34 is in contact with the heat sink assembly 20, so that the heat sink assembly 20 absorbs the heat and then dissipates it, and the heat of the cold compressing surface l I can be effectively reduced.

[0028] The heat sink assembly 20 includes a plurality of heat sinks 21 arranged equidistantly.

One end of each heat sink 21 contacts the heat outputting portion 32, so that the heat of the heat outputting portion 32 can be quickly conducted to the heat sink 21.

The gap between the heat sinks 21 is used for external cooling medium to pass through, so that the heat absorbed by the heat sinks 21 can be absorbed and taken away by the external cooling medium, to realize effective heat dissipation of the heat outputting portion 32.

[0029] Referring to FIGS. 4 and 5, as an embodiment, the housing 40 includes an upper housing 43 and a lower housing 44.

The upper housing 43 and the lower housing 44 can be assembled by screwing or clamping, or can be integrated by processing.

Optionally, the upper housing 43 and the lower housing 44 arc assembled by snap-fitting, so as to facilitate the disassembly and the maintenance of the upper housing 43 and the lower housing 44.

The depilator can also directly use an external power supply, such as dry capacitors, or energy storage capacitors, which is convenient to store and carry, and can be used outside.

The circuit device can be connected to an external circuit to charge the power supply device, and can control a start, a stop, power regulation, and heat protection, and the like of the depilator 100.

[0031] It can be understood that the heat inside a fuselage of a traditional depilator is large at present, which is likely to cause short-circuit, burnout, explosion and other hazards to the components inside the fuselage of the depilator.

The heat conducting plate 30 of the present disclosure can not only effectively cool down the cold compressing portion 10, so that the cold compressing portion IO can effectively cold compress the skin of the user with high comfort and no damage to the skin, but also cool down the 4 CA 03183178 2022- 12- 16 components in the receiving space of the depilator too, so that the fuselage of the depilator too is fully cooled, which can prevent internal temperature of the depilator 100 from over heating and causing harm.

Specifically, the components in the heat removal assembly, the circuit device, and the power supply device of the depilator 100 of the present disclosure all generate heat during operation, the heat conducting plate 30 can be in contact with at least part of the heat source components of the heat removal assembly, the circuit device, and the power supply device, to absorb the heat of the heat source components in the heat removal assembly, the circuit device, and the power supply device, so that the heat in the heat removal assembly, circuit device, and power supply device can be removed by the heat conducting plate, to achieve rapid cooling of the internal components of the depilator l00, avoid excessive heat in the receiving space of the depilator 100, and prevent the heat removal assembly, the circuit devices, and the power supply devices and other devices from dangerous situation such as short-circuiting, burning, and explosion.

[0032] Circuit devices often have some of their control components set on a surface of the housing.

For example, components such as control buttons, power switches, and the like are set on the surface of the hand-held portion.

The user can control the depilator I 00 by manipulating a power switch to adjust a start, a stop, and a gear control of the depilator too.

[0033] The heat removal assembly is arranged in the receiving space and close to the head portion 42, and can be fixed in the receiving space .of the housing 40.

The circuit device and the power supply device are both installed inside the housing, optionally inside the hand-held portion.

In this embodiment, they are installed on a back side of the heat removal assembly, which is one side of the heat removal assembly away from the human skin.

The design expands a contact range of the external cooling medium allowed in the receiving space to achieve an overall cooling effect inside the housing.

Furthermore, referring to FIG. 5, the depilator JOO further includes a plurality of heat source components.

The heat conducting plate 30 further has a plurality of secondary heat absorbing portions 37.

Each of the secondary heat absorbing portions 37 is in contact with at least some of the plurality of heat source components 50 to absorb heat of the at least some of the plurality of heat source components 50. (0034] In the present embodiment, the plurality of heat source components 50 are elements provided in the heat removal assembly, the circuit device, and the power supply device.

The plurality of heat source components 50 may be arranged in a plurality of positions in the receiving space.

The secondary heat absorbing portion 37 extends from one side of the heat outputting portion 32.

The secondary heat absorbing portion 37 and the main heat absorbing portion 31 arc respectively located on both sides of the heat outputting portion 32, that is, the heat source components 50 arc located away from the cold compressing portion I 0, so as to prevent the heat of the heat source components 50 from being conducted to the cold compressing portion 10, and ensure the cooling effect of the cold compressing portion IO.

The heat source components 50 and the cold compressing portion IO are in contact with a same surface of the heat conducting plate 30.

For example, both the heat source components 50 and the cold compressing portion IO are in contact with one surface of the first plate 33, and the heat sink assembly 20 is in contact with one surface of the second plate 34.

It can be understood that the lirst plate 33 can effectively absorb the heat of CA 03183178 2022- 12- 16 the cold compressing portion IO and the heat source components 50 from the main heat absorbing portion 31 and the secondary heat absorbing portion 37, and conduct the heat to the second plate 36 through the heat conducting medium 35 and the heat conducting net 36, and the second plate 34 conducts the heat to the heat sink assembly 20 or directly dissipates from the heat outputting portion 32, so as to effectively reduce the heat of the cold compressing portion 10 and the heat source components 50.

[0035] In the present embodiment, the heat conducting plate 30 is in contact with the cold compressing portion IO, the heat source components 50, and the heat sink assembly 20, such that the heat conducting medium 35 can quickly absorb the heat of the cold compressing portion IO and the heat source components 50, and quickly conduct the heat to the heat sink assembly 20.

The heat conducting net 36 has a larger arrangement area on the first plate 33 and the second plate 34, which effectively increases the heat conducting efficiency of the heat conducting plate 30.

[0036] Optionally, the first plate member 33 and second plate member 34 are copper plates.

The heat conducting net 36 is a copper net having a capillary structure, allowing the contact area of the heat conducting medium 35 contacting the first plate 33 and the second plate 34 to be larger and allowing the heat conducting medium 35 to contact the first plate 33 and the second plate 34 more evenly, improving the heat conducting efficiency of the heat conducting plate 30.

[0037] Optionally, a cavity is sealed between the first plate 33 and the second plate 34 and is vacuumizcd, and the heat conducting medium 35 and the heat conducting net 36 are received in the cavity.

[0038] Optionally, the heat conducting medium 35 is a cooling nuid, preferably water.

[0039] Optionally, edges of the first plate 33 and the second plate 34 are sealed and pressed with each other, such that the heat conducting plate 30 is structurally stable, and h~at may be prevented from entering an interior of the heat conducting plate 30.

[0040] Furthermore, referring to FIGS. 5, 6 and 7, the depilator JOO defines a cooling passage 60 (shown by a dashed line in FIG. 5).

The cooling passage 60 introduces external cooling medium.

The heat outputting portion 32, the secondary heat absorbing portion 37, the heat source components 50 and the heat sink assembly 20 are all located in the cooling passage 60.

[0041] In the present embodiment, the housing 40 defines a cooling inlet 45, a first cooling outlet 46, a second cooling outlet 47, and a third cooling outlet 49.

The cooling passage 60 is formed between the cooling inlet 45 and the first cooling outlet 46, and is formed between the cooling inlet 45 and the second cooling outlet 47, and is also rormed between the cooling inlet 45 and the third cooling outlet 49.

The cooling inlet 45 and the first cooling outlet 46 are defined on the hand-held portion 41.

The first cooling outlet 46 is defined on a peripheral side of the housing 40, so that the first cooling outlet 46 can be close to an inner middle position of the depilator JOO, which is convenient for discharging the heat in the inner middle position of the depilator IOO.

The housing 40 defines the first cooling outlet 46, the second cooling outlet 47 and the third cooling outlet 49, such that the cooling passage 60 has three parts.

The first part of the cooling passage 60 is formed between the cooling inlet 45 and the first cooling outlet 46, to directly discharge the most heat of the cold compressing portion I 0.

The second part of the cooling passage 60 is 6 CA 03183178 2022- 12- 16 formed between the cooling inlet 45 and the third cooling outlet 49, to contact the heat conducting plate 30 through the cold compressing portion IO, so that the heat of the cold compressing portion IO is conducted to the heat conducting plate 30, and then dissipated through the third cooling outlet 49.

The third part of the cooling passage 60 is formed between the cooling inlet 45 and the second cooling outlet 47, to dissipate the heat of the heating deice 50 through the second cooling outlet 47.

The cooling inlet 45, the first cooling outlet 46 and the third cooling outlet 49 are all defined on the hand-held portion 41.

The first cooling outlet 46 is defined on the peripheral side of the hand-held portion 41.

The cooling inlet 45 and the third cooling outlet 49 are defined on a same side of the hand-held portion 41.

The third cooling outlet 49 is adjacent to the cooling inlet 45.

This design is to enable the heat of the cold compressing portion 10 to be distinguished at the same time, and the cooling medium can be sucked and discharged quickly, which improves the cooling efficiency of the cold compressing portion IO.

The second cooling outlet 47 is defined at the tail end 48 of the housing 40, that is, at the end of the housing 40 away from the head portion 42.

The reason why the second cooling outlet 47 is arranged farther from the cooling inlet 45 is to increase a distance through which the cooling medium nows, make the cooling range wider. [0042) In this embodiment, the depilator I 00 defines the cooling passage 60.

The external cooling medium is introduced into the cooling passage 60.

The heat outputting portion 32, the secondary heat absorbing portion 37, the heat source components 50 and the heat sink assembly 20 are all located in the cooling passage 60.

Their heat can be effectively absorbed by the cooling medium to achieve cooling, and the overall temperature in the receiving space inside the depilator 100 can be reduced.

The cold compressing portion 10 is completely isolated from the cooling passage 60, so that the cooling of the cold compressing portion IO is independent of the cooling of the heat conducting plate 30, the heat sink assembly 20, and the heat source components 50. [0043) In this embodiment, the heat outputting ponion 32 of the heat conducting plate 30 and the heat sink assembly 20 are adjacent to the cooling inlet 45.

The heat source components 50 are adjacent to the first cooling outlet 46 and the second cooling outlet 47.

The cooling passage 60 introduces the external cooling medium from the cooling inlet 45 so that the external cooling medium preferentially contacts the heat outputting portion 32 of the heat conducting plate 30 and the heat sink assembly 20 so that the heat of the heat outputting portion 32 of the heat conducting plate 30 and the heat sink assembly 20 is preferentially absorbed by the cooling medium to achieve rapid cooling.

After the cooling medium passes through the heat sink assembly 20 and the heat outputting portion 32 of the heat conducting plate 30, it continues to now to the plurality of the heat source components 50, so that the heat of the heat source components 50 is absorbed by the cooling medium and taken away by the cooling medium, and the cooling medium finally flows out from the first cooling outlet 46 and the second cooling outlet 47 to achieve overall effective heat dissipation.

[0044] Optionally, the radiator assembly 20 and the cooling inlet 45 are abutted against each other through a sealed structure, so that the heat sink assembly 20 effectively receives the external cooling medium that enters from the cooling inlet 45, and reduces a flow resistance of the heat sink assembly 20 to the external 1 CA 03183178 2022- 12- 16 cooling medium, to ensure the heat conducting efficiency.

The heat outputting portion 32 of the heat conducting plate 30 is in contact with one side of the heat sink assembly 20 away from the cooling inlet 45.

[0045] Optionally, the heat conducting plate 30 defines a through slot 38, and the through slot 38 fonns a part of the cooling passage 60.

The heat outputting portion 32 is arranged on a peripheral side of the through slot 38.

After the external cooling medium passes through the heat sink assembly 20, it flows through the through slot 38, so that the heat outputting portion 32 is in contact with the external cooling medium.

Of course, part of the cooling medium flows through the main heat absorbing portion 31 and the secondary heat absorbing portion 37 of the heat conducting plate 30 after passing through the heat sink assembly 20, so that the main heat absorbing portion 31 and the secondary heat absorbing portion 37 are effectively cooled.

[0046] Referring to FIGS. 5 and 8, in this embodiment, the heat removal assembly 70 includes a lamp 71, a reflecting plate 72 and a lamp holder 73.

The lamp 71, the reflecting plate 72 and the lamp holder 73 are all located in the cooling passage 60.

The lamp 71, the reflecting plate 72 and the lamp holder 73 are all fixed in a part of the receiving space adjacent to the head portion, to reduce a path of the light emitted by the lamp 71 and prevent the heat of the emitted light from being conducted to more devices, so as to decrease heat gathered in the receiving space.

The lamp 71, the reflecting plate 72 and the lamp holder 73 arc adjacent to the first cooling outlet 46, so that the cooling medium can immediately discharge the heat from the first cooling outlet 46 after absorbing the heat of the lamp 71, the reflecting plate 72 and the lamp holder 73, effectively reduce the heat of the lamp 71, the reflecting plate 72 and the lamp holder 73.

The lamp 71 is directly opposite to the cold compressing portion IO, and the light emitted by the lamp 71 exits through the cold compressing portion 10.

The reflecting plate 72 is located on one side of the lamp 71 away from the cold compressing portion 10.

The reflecting plate 72 condenses and reflects the light of the lamp 71, to increase the light concentration of the cold compressing portion 10.

The two ends of the reflecting plate 72 have openings, so that the cooling medium flows through one opening of the reflecting plate 72 to the other opening, and the external cooling medium contacts the peripheral side of the lamp 71 to form convection and effectively cool the lamp 71.

The lamp holder 73 fixes both ends of the lamp 71.

It can be understood that both the reflecting plate 72 and the lamp holder 73 can form the heat source components 50.

That is, the secondary heat absorbing portion 37 of the heat conducting plate 30 can be in contact with the reflecting plate 72 and the lamp holder 73, so that the heat conducting plate 30 can effectively absorb the heat of the reflecting plate 72 and the lamp holder 73, and reduce the heat of the reflecting plate 72 and the lamp holder 73, thereby reducing the heat of the heat removal assembly 70 as a whole, and further reducing the heat of the cold compressing portion l 0.

[0047] Furthermore, please refer to FIG. 5, FIG. 8 and FIG. 9, the depilator 100 includes a cool driving portion 80 arranged in the cooling passage 60.

The cool driving portion 80 is configured to drive the external cooling medium in the cooling passage 60 to flow.

[0048] In this embodiment, the cool driving portion 80 is fixed in the receiving space and located at a portion of the heat removal assembly away from the cold compressing portion I 0.

The cool driving portion 8 CA 03183178 2022- 12- 16 drives the external cooling medium in the cooling passage 60 to flow through a power device, so that the external cooling medium can effectively take away the heat in the depilator 100.

The cool driving portion 80 defines a driving inlet 81 and a driving outlet 82.

The driving inlet 81 is directly opposite to the through slot 38, so that the external cooling medium can quickly flow through the heat sink assembly 20 and the heat outputting portion 32 or the heat conducting plate 30, to effectively cool down the heat outputting portion 32 of the heat conducting plate 30.

The driving outlet 82 is opposite to the heat removal assembly 70 so that the external cooling medium can be guided to the lamp 71, the retlecting plate 72 and the lamp holder 73 intensively, and the flow rate of the cooling medium around the heat removal assembly 70 is increased.

[0049] Optionally, the cool driving portion 80 is a fan.

The external cooling medium is air.

For example, the cool driving portion 80 is a centrifugal fan, an axial fan, a mixed tlow fan, and a cross flow fan.

Preferably, the cool driving portion 80 is a centrifugal fan, so that the external air flows mainly in the radial direction after entering an impeller of the fan axially. [0050) Specifically, the cool driving portion 80 includes a shell 83 and a fan blade fixed in the shell 83.

The driving inlet 81 and the driving outlet 82 are defined in the shell 83.

The bottom of the shell 83 is fixed on inner side of the lower housing 44.

The driving inlet 81 is defined on a top of the shell 83.

The driving outlet 82 is defined on a peripheral side of the shell 83.

The heat conducting plate 30 is fixed on the top of the shell 83.

The shell 83 effectively supports the heat conducting plate 30, so that the heat outputting portion 32 of the heat conducting plate 30 is effectively stabilized.

The depilator 100 also includes a heat conducting support 39 fixed in the housing 40 and stably connected with the shell 83.

The heat conducting support 39 effectively supports the main heat absorbing portion 31 of the heat conducting plate 30.

The heat conducting support 39 isolates the cooling medium of the driving outlet 82 from the heat conducting plate 30, to avoid the cooling medium at the driving outlet 82 from tlowing back to the heat conducting plate 30, and to ensure that the heat conducting plate 30 effectively cools the cold compressing portion IO.

[0051] More specifically, the top of the shell 83 defines a fixing groove 84.

Preferably, the secondary heat absorbing portion 37 of the heat conducting plate 30 is in contact with the processor 92.

The secondary heat absorbing portion 37 absorbs heat on the processor 92, so that the heat of the processor 92 is effectively reduced.

The circuit board 91, the processor 92, and the capacitor 94 are all on a path of the external cooling medium from the driving outlet 82 to the second cooling outlet 47.

[0055] Furthermore, the cold compressing portion IO includes a cold compressing member 19 and a cooling member I 8 for cooling the cold compressing member 19.

[0056] In this embodiment, both the lamp 71 and the cooling member 18 are electrically connected to the circuit board 91.

The cold compressing member 19 is fixed on the heat conducting support 39, so that the cooling member 18 is firmly fixed to between the cold compressing member 19 and the heat conducting support 39, allowing the main heat absorbing portion 31 to contact the cooling member 18.

The cooling member 18 is closely in contact with the cold compressing member 19 so as to cool the cold compressing member 19. A filter is also arranged between the cold compressing member 19 and the lamp 71 to prevent the heat of the lamp 71 from being conducted to the cold compressing member 19.

The retlecting plate 72 is arranged on one side of the lamp 71 away from the cold compressing member 19, so that the light emitted by the lamp 71 is concentrated on the cold compressing member 19.

[0057] Preferably, the cold compressing member 19 is made of crystal material, specifically sapphire, K9 glass, crystal glass, and all materials that meet the requirements of light-transmitting ciystals may be used, and optionally, sapphire material.

[0058] It can be understood that, since the cold compressing member 19 is made of sapphire, the cold compressing member 19 can also be served as a light outlet.

When the lamp 71 emits light, the sapphire has a strong heat conducting efficiency, so that the cooling member 18 and cold compressing member 19 can efficiently perform heat exchanging, so as to achieve the best cooling effect.

Optionally, the cold compressing member 19 can be a circular plate or a rectangular plate, which is not limited here.

The specific wavelength and frequency are determined according to the usage.

[0060] In this embodiment, the depilator l00 includes a skin detection part, which can be integrated in the cold compressing member 19.

The skin detection unit uses a capacitive touch detection principle to electrically connect the circuit board 91.

When the cold compressing member 19 touches the skin, an internal preset capacitance detection device also detects whether the depilator IOO actually touches the skin, so as to reduce a safe question caused by mis-operations of a user.

[0061] In this embodiment, the shape of the reflecting plate 72 is not limited, and only the light of the lamp 71 is concentrated in a direction of the cold compressing member 19.

Optionally, the reflecting plate 72 is U-shaped, and the opening of the reflecting plate 72 faces the cold compressing member 19.

The lamp 71 is located in a center of the U-shaped opening of the reflecting plate 72.

In addition to concentrating light, it can also prevent the lamp 71 from dissipating heat to other places during operation.

[0062] In this embodiment, the cooling member 18 is optionally a refrigeration element in a semiconductor refrigeration mode.

The cooling member 18 includes a heat conducting surface 12 and a cooling surface 181 that are arranged oppositely.

The cooling surface I 81 is closely attached to the cold compressing member 19 to cool the cold compressing member 19.

[0063] It can be understood that due to a special principle of the depilator 100 using light hair removal technology, a lot of heat will be generated when the light is emitted.

At the same time, when the cold compressing member 19 touches the skin, in order Lo prevent the light from causing the user to have a burning sensation, the inside of the body of the depilator I 00 needs to be provided with a cooling structure.

No matter how the temperature is cooled, the heat will be generdted under the heat exchange.

The heat conducting surface 12 of the cooling member 18 is close to the main heat absorbing portion 31 of the heat conducting plate 30, making the cold compressing member 19 fast cooling.

In addition to the heating of the cooling member 18, there are also the plurality of heat source components 50 in the receiving space.

[0064] It can be understood that the external cooling medium is sucked in from the cooling inlet 45, enters the driving inlet 81 and passes through the driving outlet 82, passes through the lamp 71 along the way, so that the heat of the lamp 71 reduces, and then passes through the circuit board 91, the processor 92 and the capacitor 94 inside the housing 40, and finally discharges from the first cooling outlet 46 and the second cooling outlet 47, thereby forming a path of the cooling passage 60 so that the cooling passage 60 cools the area passing by the external cooling medium along the way. 11 CA 03183178 2022- 12- 16

[0065] It can be understood that the heat conducting plate 30 and the heat sink assembly 20 are combined into one structure.

The outer surface of the heat conducting plate 30 and the inner wall of the housing 40 cooperatively define a space.

The cooling inlet 45 is attached to define another cooling passage 60, so that the heating conducting plate 30 and the cooling member 18 effectively performing the cooling effect.

[0066] Based on the above embodiments where the cooling passage 60 is defined in the depilator 100, in some embodiments, the heat dissipation method of the depilator l 00 may not use a fan for cooling, or other external cooling medium, such as water, coolant, and so on, as long as the heal of two passages can be taken away by external cooling medium. [0067) A contact end surface of the cold compressing portion IO for contacting the skin and an exposed end surface of the skin detection part are located on a same side, so that when the skin is lighted and hair removed, the cold compressing member 19 contacts an irradiated area of the skin, and cold compresses the irradiated skin to cool down the skin, so as to reduce a burning sensation of the irradiated skin, and the cold compressing member 19 can reach a low temperature close to zero, so that the skin near the light outlet can reach infinitely close to a freezing point, which can reduce the burning sensation of the skin, and short-tenn contact will not cause skin damage.

[0068] In some embodiments, more than the two cooling passages 60 described in this embodiment are provided.

In addition to the cooling member 18 and the lamp 71, a plurality of cooling passages 60 can also be provided, and the plurality of cooling passages 60 can be used for cooling down the plurality of heat source components 50. (0069) In some embodiments, the depilator 100 is provided with a luminous body, and the structural features described in all the above embodiments are used. [0070) In the second embodiment, please referring to FIG. IO and FIG. 11, which is substantially the same as the first embodiment shown in FIG. 5, except that the heat conducting plate 30 is in a "T" shape. A wider end of the heat conducting plate 30 completely covers the cold compressing portion IO to improve a heat absorption efficiency of the cold compressing portion IO of the heat conducting plate 30. A narrow end of the heat conducting plate 30 partially contacts the heat sink assembly 20.

That is, the main heat absorbing portion 31 is arranged at the wider end of the heat conducting plate 30.

The heat sink assembly 20 is provided with a bonding plate 22 (see FIG. 10) that is bonded to the plurality of heat sinks 21, and the bonding plate 22 is also bonded to the narrower end of the heat conducting plate 30, to increase the heat conducting efficiency of the narrower end of the heat conducting plate 30 and the heat sink assembly 20.

That is, the heat outputting portion 32 is arranged at the narrower end of the heat conducting plate 30.

The portion of the heat sinks 21 that is not covered by the heat conducting plate 30 is used to guide the cooling medium to pass, so that the heat sink assembly 20 and the heat conducting plate 30 are cooled.

Of course, in other embodiments, the heat conducting plate 30 can also be arranged in any other shape. [0071) Those skilled in the art should also understand that if all or part of the components of the depilator I 00 of the present disclosure are combined by means of fusion, physical connection, and so on.

For example, positions where the components are arranged in the heat removal assembly 70 may be changed; or the 12 CA 03183178 2022- 12- 16 components are integrally formed; or the components are detachably connected with each other; or the number of the components may be variable, and shapes of features that are not used as functional components may be changed.

Any combined component can form a device/apparatus with a specific function.

Using such a device/apparatus to replace the corresponding component of the present disclosure also falls the protection scope of the present disclosure.

[0072] Compared with the prior art, the depilator 100 of the present disclosure has the following advantages: [0073) I.

The depilator 100 is arranged with the heat conducting plate 30 having a composite structure.

The heat conducting plate 30 is arranged with the first plate 33, the second plate 34 laminated on the first plate 33, and the heat conducting medium 35 and the heat conducting net 36 sealed between the first plate 33 and the second plate 34, to increase the heat conducting efficiency of the heat conducting plate 30.

The main heal absorbing portion 31 of the heat conducting plate 30 absorbs the heat of the cold compressing portion I 0, and the heat outputting portion 32 of the heat conducting plate 30 dissipates the heat through the heat sink assembly 20, so that the heat of the cold compressing portion l 0 is rapidly reduced.

The heat conducting plate 30 is made of copper, which increases the heat conducting efficiency of the heat conducting plate 30, so that the main heat absorbing portion 31 can effectively and quickly absorb heat, and the heat outputting portion 32 can effectively and quickly dissipate heat. [0074) 2.

The depilator is a household portable depilator, which is relatively small for the convenience of use's hand holding.

Therefore, in the case of a large amount of heat being accumulated, if the heat cannot be dissipated and cooled in time, it will bring strong pain, redness and swelling to the user, and even cause safety issues.

In the past, only one inlet and one outlet are defined in the portable depilator to form a passage for heat dissipation.

However, there are more than one heat-generating components inside the portable depilator.

For example, a plurality of heat-generating components rely on one inlet and one outlet for heat dissipation.

The heat generated by the heat-generating components will affect each other, reducing the heat dissipation effect, and the working environment of the heat-generating components in the passages will be affected.

For example, the cooling member 18 and the lamp 71 that both generate heat are placed in the same cooling passage 60.

When the cooling medium passes through one of the cooling member 18 and the lamp 71, it will conduct its heat to the other component.

Therefore, in this present disclosure, a portable depilator l 00 is provided with a plurality of cooling passages 60, and different heat generating components can be set in different cooling passages 60, its cooling passage 60 can have one inlet corresponding to a plurality of outlets, or a plurality of inlets corresponding to a plurality of outlets.

Therefore, under the action of the heat conducting components, the external cooling medium can dissipate heat and reduce the temperature of multiple heal generating components inside the portable depilator 100, and will not interfere with each other. [0075] 3.

Two isolated cooling passages 60 are provided to cool the cooling member 18 and the lamp 71 separately.

Unlike the previous method that only uses a sealed cavity to protect the cooling member 18 and ventilate it separately, other heat source components 50 such as the circuit device, the power supply device, 13 CA 03183178 2022- 12- 16 the lamp and the like which also generate heat are not considered, especially when used for a long time, the heat of the lamp 71 will be very high, so the cooling effect is not complete. (0076] In this embodiment, not only the airflow of the cooling member 18 is protected, but also, in at least two passages, the heat on the cooling member 18 is quickly conducted by the composite heat conducting plate 30.

Due to the complete isolation and the heat conduction provided by the heat conducting plate 30, the external cooling medium can only be discharged from the corresponding outlet after the heat exchange is completed.

It can not only cool the cooling member 18, but also other heat source components 50 inside the depilator 100, such as the circuit board 9 I, the capacitor 94, the processor and lhe lamp 71, which can further improve the cooling effect of the cold compressing member 19, and reduce the cooling heat as much as possible to the cooling temperature that temporarily paralyzes the skin, thereby reducing the strong pain sensation and redness of the skin caused by hair removal. [0077] 4.

The external cooling medium that can be used by the technical means of the present disclosure can be not only the introduction of air for the fan, but also other cooling mediums, such as the use of water pumps, extraction of water or cooling liquid, and so on. [0078] 5.

Between the driving inlet 81 of the driving cooling part and the cooling inlet 45 of the housing 40, the heat outputting portion 32 of the heat conducting plate 30 and the heat sink assembly 20 are arranged.

One end of the heat conducting plate 30 extends to the cooling member 18 to make the cool driving portion 80 introduce the external cooling medium, and further cool the heat conducting plate 30 and the cooling member 18 simultaneously. [0079] 6.

There are three cooling outlets on the housing 40.

One cooling outlet is arranged on the housing 40, and is arranged on a same side with the cooling inlet 45 and adjacent to the cooling inlet 45, so that the cooling medium can enter and discharge quickly, improve the heat conducting efficiency of the heat conducting plate 30.

One cooling outlet is arranged at a lateral direction of the housing 40, that is, the side of the cold compressing portion 10, can quickly dissipate most of the heat of the cold compressing portion 10 and reduce the heat of the cold compressing portion 10.

One cooling outlet is arranged at a tail end of the depilator 100 away from the cold compressing portion 10, so that the cooling medium flows in the depilator 100 and is discharged after a longer distance, so that the heat of the heating devices 50 flowing through is removed, and the heat of the heating devices 50 is reduced. [0080] 7.

The cold compressing member 19 is exposed from the head portion 42 of the housing 40 and actually contacts the human skin, so that the user can feel a cold compressing effect of the cold compressing member 19 while using the depilator I 00 to remove hair, thereby reducing the strong pain sensation caused by the heat generated by the depilator 100. [0081) 8.

The cold compressing member I 9 is made of crystal material, which can be made of sapphire.

Sapphire has strong heat conductivity, which reduces the heat of the light emitted by the depilator 100 while maintaining the light transmittance. (0082] 9.

The cooling member 18 can be a semiconductor refrigeration chip, which can effectively improve the cooling effect of the depilator 100. 14 CA 03183178 2022- 12- 16

[0083] I 0.

The depilator I 00 is arranged with a skin detection part.

The skin detection part detects whether the depilator is actually contacting the skin while the cold compressing portion IO is contacting the skin.

In this way, safety problems caused by mis-operations performed by the user may be reduced, and the operating efficiency of the depilator LOO is increased.

[0084] The above description shows embodiments of the present disclosure.

Any ordinary skilled person in the art may perform a number of improvements and embellishments without departing from the principles of the present disclosure.

The improvements and embellishments shall be within the scope of the present disclosure.
