The cool driving portion 50 is fixed on one side of the hair removal device 30 away from the cold compressing portion 11, and is configured for driving external cooling medium to flow through a part of the heat conducting portion 40 away from the cold compressing portion 11, so that the heat of the heat conducting portion 40 can be taken away by the external cooling medium.

The head portion 10 includes the cold compressing portion 11 and the illuminating portion 12 arranged around the cold compressing portion 11. The illuminating portion 12 is configured to emit light for caring the skin of the user. The hair removal device 30 is directly opposite to the cold compressing portion 11, and is configured to emit light to the cold compressing portion 11, so that the cold compressing portion 11 can emit light to irradiate hair follicles of the skin of the user, and use the light to penetrate the skin to irradiate the hair follicles for hair removal, thus, the depilator 100 has both functions of hair removal and skin care.

It can be understood that the depilator 100 uses the cold compressing portion 11 to contact the skin of the user, and the cold compressing portion 11 emits light, and the light penetrates the skin to irradiate the hair follicles for hair removal. The cold compressing portion 11 can quickly cool down to reduce a burning sensation caused by the light and ensure comfort. The illuminating portion 12 emits light to the skin of the user, and the light is configured to care the skin of the user, so that the depilator 100 has multiple functions.

In this embodiment, the head portion 10 is located at one end of the hand-held portion 20. The hand-held portion 20 is columnar, so that the user can hold the hand-held portion 20. The cold compressing portion 11 is located in the head portion 10 and includes a cold compressing surface 111 exposing the head portion 10. The illuminating portion 12 is completely located in the head portion 10 and emits light from a periphery of the cold compressing surface 111. The light may be visible light such as red light, green light, yellow light, or so on. The hair removal device 30 is located at a part of the hand-held portion 20 adjacent to the head portion 10. The hair removal device 30 is located on one side of the cold compressing portion 11 away from the cold compressing surface 111. The hair removal device 30 emits light toward the cold compressing portion 11, and the light passes through the cold compressing portion 11 and irradiates the hair follicles of the skin of the user, to achieve hair removal. A part of the heat conducting portion 40 is in contact with the cold compressing portion 11, to absorb the heat of the cold compressing portion 11, and the other part of the heat conducting portion 40 is far away from the cold compressing portion 11, to conduct heat away, and to realize heat conduction to the cold compressing portion 11.

In this embodiment, the cool driving portion 50 drives the external cooling medium to flow into the depilator 100, so that the external cooling medium can take away the heat of the hair removal device 30 and the heat conducting portion 40. The cool driving portion 50 drives the external cooling medium to flow through a power device, so that the external cooling medium can effectively take away the heat in the depilator 100.

Optionally, the cool driving portion 50 is a fan. The external cooling medium is air. For example, the cool driving portion 50 is a centrifugal fan, an axial fan, a mixed flow fan, and a cross flow fan. Preferably, the cool driving portion 50 is a centrifugal fan, so that the external air enters an impeller of the fan axially and flows mainly in a radial direction.

Furthermore, the illuminating portion 12 includes a light source substrate 121 arranged around the cold compressing portion 11 and a plurality of lamp beads 122 arranged on the light source substrate 121. The plurality of lamp beads 122 are arranged equidistantly around the cold compressing portion 11 in a circumferential direction.

In this embodiment, the light source substrate 121 defines a through hole 123, and the cold compressing portion 11 passes through the through hole 123, to achieve the light source substrate 121 to be arranged around the peripheral side of the cold compressing portion 11. One surface of the light source substrate 121 where the lamp beads 122 are mounted is parallel to the cold compressing surface 111. The lamp beads 122 are located on one surface of the light source substrate 121 close to the cold compressing surface 111. The light source substrate 121 drives the plurality of lamp beads 122 to emit light. The lamp bead 122 is an LED (Light Emitting Diode, light-emitting diode). The lamp bead 122 can convert the emitted light energy into intracellular energy, accelerate a cycle of a cell growth process, stimulate fiber cells to produce collagen, and will not cause any damage or discomfort to the skin. The plurality of lamp beads 122 are equidistantly arranged the cold compressing portion 11 in a circumferential direction, so that the head portion 10 emits light uniformly on the peripheral side of the cold compressing portion 11, and improves a skin care effect to the user. The plurality of lamp beads 122 can all emit light of the same color, or light of multiple different colors.

It can be understood that the light emitted by the lamp beads 122 acts on the skin of the user via the head portion 10 and cares the skin of the user. By arranging the plurality of lamp beads 122 on the depilator 100, the depilator 100 has a function of hair removal and also has a function of skin beauty, and the lamp beads 122 can repair the skin damage caused by the hair removal device 30 during hair removal.

Specifically, the depilator 100 can set a switch to adjust the lamp beads 122 to emit light of different colors. The plurality of lamp beads 122 can emit any one or a combination of multiple colors such as red light, blue light, yellow light and so on. The plurality of lamp beads 122 in the illuminating portion 12 include at least one red lamp emitting red light, at least one blue lamp emitting blue light, and at least one yellow lamp emitting yellow light. The lamp beads 122 emitting light of different colors are arranged alternately in sequence.

Optionally, the lamp bead 122 can emit red light, and the red light exits through the head portion 10 and irradiates the skin of the user. The red light emitted by the lamp bead 122 can improve the activity of skin cells and promote the metabolism of skin cells. The red light can also improve fine wrinkles and prevent skin from sagging and wrinkle removal. Specifically, the wavelength of the red light is 620 nm-660 nm. The wavelength of the red light may also specifically be 630 nm, 632 nm, 635 nm, 637 nm, 640 nm, 643 nm, 647 nm or 650 nm. Preferably, the wavelength of the red light is 630 nm. Red light waves in this wavelength range can stimulate the blood flow of the skin, promote the growth of collagen, stimulate cell activity and promote renewal growth, and can achieve the effects of whitening and rejuvenating skin and repairing skin damage.

Optionally, the lamp bead 122 can emit blue light, and the blue light is emitted through the head portion 10 and irradiated on the skin of the user. The blue light emitted by lamp bead 122 can kill bacteria on the skin and inhibit the growth of bacteria. Blue light can also improve sebum, reduce inflammation, acne, and shrink pores. Specifically, the blue light has a wavelength of 450 nm-490 nm. Specifically, the wavelength of the blue light may specifically be 450 nm, 460 nm, 467 nm, 480 nm, 485 nm or 490 nm. Preferably, the wavelength of the blue light is 470 nm. The blue light waves in this wavelength range have a calming and anti-inflammatory effect and can inhibit the growth of bacteria.

Optionally, the lamp bead 122 can emit yellow light, and the yellow light is emitted through the head portion 10, and irradiated on the skin of the user. The yellow light emitted by the lamp bead 122 can improve dark yellow skin and freckle removal effects. Specifically, the wavelength of the yellow light is 567 nm-607 nm, and the wavelength of the yellow light may also be 577 nm, 580 nm, 581 nm, 585 nm, 588 nm, 590 nm, 595 nm or 597 nm. Preferably, the wavelength of the yellow light is 590 nm. The yellow light wave in this wavelength range has an effect of improving the exchange rate of cell nutrients, and can also replenish energy to the skin of the human body and improve the roughness of the skin.

With the depilator 100 of this design, while the cold compressing portion 11 is in contact with the skin to remove hair, the lamp beads 122 can further play a role of skin care and skin beauty. The integrated design of the lamp beads 122 and the cold compressing portion 11 can combine skin care and hair removal together, the functions are rich and the user experience is improved.

Furthermore, the head portion 10 further includes a light cover 13. The light cover 13 covers the plurality of lamp beads 122, and defines a mounting hole 131 for clearance fit with the cold compressing portion 11. One surface of the cold compressing portion 11 away from the hair removal device 30 is flush with one surface of the light cover 13 away from the lamp beads 122.

In this embodiment, the light cover 13 includes an ending plate 132 and a connecting plate 133 extending from a periphery of the ending plate 132. The inner sides of the ending plate 132 and the connecting plate 133 form a receiving cavity. The lamp beads 122 and the light source substrate 121 are received in the receiving cavity, so that the light cover 13 protects the lamp beads 122 and the light source substrate 121. The light emitted by the lamp beads 122 passes through the ending plate 132 and is emitted to the skin of the user. The light cover 13 can be made of transparent or semi-transparent materials. One surface of the ending plate 132 away from the lamp beads 122 is flush with the cold compressing surface 111, so that one surface of the head portion 10 that contacts the skin of the user is smooth, and the comfort is increased. The connecting plate 133 is configured to detachably connect with the hand-held portion 20 to facilitate the disassembly and maintenance of the lamp beads 122 and the light source substrate 121.

Furthermore, the hand-held portion 20 includes a housing 21. One end of the housing 21 is abutted with the light cover 13. The cold compressing portion 11, the hair removal device 30, the cool driving portion 50 and the heat conducting portion 40 are all fixed in the housing 21.

In this embodiment, the housing 21 includes an upper housing 22 and a lower housing 23. The upper housing 22 and the lower housing 23 can be assembled by screwing or clamping, or can be integrally processed. Optionally, the upper housing 22 and the lower housing 23 are assembled by snap-fitting, so as to facilitate disassembly and maintenance of the upper housing 22 and the lower housing 23. The housing 21 defines a receiving space 211. The hair removal device 30, the cool driving portion 50 and the heat conducting portion 40 are all fixed in the receiving space 211. The cool driving portion 50 drives the external cooling medium to flow into the housing 21, so that both the hair removal device 30 and the heat conducting portion 40 can contact the external cooling medium, and finally use the external cooling medium to absorb the heat of the hair removal device 30 and the heat conducting portion 40, and discharge the heat from the housing 21. The housing 21 defines a head port 212 between the upper housing 22 and the lower housing 23, and the connecting plate 133 is inserted into the head port 212. The connecting plate 133 is fixedly coupled to the upper housing 22 and the lower housing 23, and an outer surface of the connecting plate 133 is flush with an outer surface of the upper housing 22 and an outer surface of the lower housing 23. The housing 21 also includes a tail cover 213 opposite to the head port 212 (see FIG. 3). The tail cover 213 is fixedly connected between the upper housing 22 and the lower housing 23, and is located away from the head portion 10. The tail cover 213 is configured for a cable passing through and entering into the receiving space 211, so as to facilitate the depilator 100 to obtain power or obtain control signals.

Furthermore, referring to FIGS. 3, 4 and 5, the housing 21 defines a first guide opening 24 and a second guide opening 25. The first guide opening 24 is adjacent to the cool driving portion 50, and the second guide opening 25 is adjacent to the hair removal device 30. A cooling channel is formed between the first guide opening 24 and the second guide opening 25. The cool driving portion 50 is configured to drive the external cooling medium in the cooling channel to flow.

In this embodiment, the first guide opening 24 is defined in the upper housing 22. The first guide opening 24 interconnects with the receiving space 211 in the housing 21. The second guide opening 25 is arranged at a joint of the upper housing 22 and the lower housing 23. The cool driving portion 50 is located in an area between the first guide opening 24 and the second guide opening 25. The cool driving portion 50 defines a first driving opening 51 abutted with the first guide opening 24 and a second driving opening 52 facing the hair removal device 30 and the cold compressing portion 11. The first driving opening 51 is configured to input or output the external cooling medium from the first guide opening 24, and the second driving opening 52 is configured to blow or suck away the cooling medium to the hair removal device 30 and the cold compressing portion 11, thereby enabling the cooling medium around the hair removal device 30 and the cold compressing portion 11 to flow, so that the cooling medium can absorb the heat of the hair removal device 30 and the cold compressing portion 11 and then discharge the heat. Specifically, the cool driving portion 50 includes a shell 53 and a fan blade fixed in the shell 53. The first driving opening 51 and the second driving opening 52 are opened in the shell 53. The shell 53 is fixed in the housing 21. The shell 53 is located on one side of the hair removal device 30 away from the cold compressing portion 11. The first driving opening 51 is opened on a top portion of the shell 53 adjacent to the upper housing 22. The second driving opening 52 is opened at one end of the shell 53 facing the hair removal device 30 and the cold compressing portion 11. The first driving opening 51 may be a cooling medium input opening, that is, the cool driving portion 50 sucks in the external cooling medium from the first guide opening 24 through the first driving opening 51. The second driving opening 52 blows the external cooling medium toward the hair removal device 30 and the cold compressing portion 11, and finally the cooling medium that has absorbed heat is output from the second guide opening 25 to the outside of the housing 21. Of course, the first driving opening 51 may also be a cooling medium output opening, that is, the first driving opening 51 outputs the cooling medium to the first guide opening 24, and the second driving opening 52 removes the cooling medium around the hair removal device 30 and the cold compressing portion 11 away, so that the heat of the hair removal device 30 and the cold compressing portion 11 is taken away.

Furthermore, the depilator 100 further includes a cooling bracket 60 fixed in the housing 21. The cooling bracket 60 defines a first cooling channel 61 and a second cooling channel 62 separated from the first cooling channel 61. The hair removal device 30 is fixed in the first cooling channel 61. A part of the heat conducting portion 40 away from the cold compressing portion 11 is fixed in the second cooling channel 62. The end of the cool driving portion 50 is abutted with the first cooling channel 62. A peripheral side of the cool driving portion 50 is abutted with the first cooling channel 61 and the second cooling channel 62. The ends of the first cooling channel 61 and the second cooling channel 62 away from the cool driving portion 50 are abutted with the second guide opening 25.

In this embodiment, the cooling bracket 60 is fixedly coupled to the cool driving portion 50, and defines the first cooling channel 61 and the second cooling channel 62 that are abutted with the second driving opening 52. The first cooling channel 61 and the second cooling channel 62 are separated. The hair removal device 30 is fixed in the first cooling channel 61, so as to use the cooling medium in the first cooling channel 61 to take away heat. The cold compressing portion 11 is fixed to the cooling bracket 60 and is opposite to the hair removal device 30, to receive the light emitted by the hair removal device 30 and emit the light. The heat conducting portion 40 is fixed to the cooling bracket 60, one part of the heat conducting portion 40 is in contact with the cold compressing portion 11, and the other part of the heat conducting portion 40 is arranged in the second cooling channel 62, to absorb the heat of the cold compressing portion 11 and guide the heat of the cold compressing portion 11 to the second cooling channel 62, and take away the heat by using the cooling medium in the second cooling channel 62.

As the cooling bracket 60 defines the first cooling channel 61 and the second cooling channel 62, both of the first cooling channel 61 and the second cooling channel 62 are abutted with the second driving opening 52 of the cool driving portion 50, and are fixed in the first cooling channel 61 by using the hair removal device 30, one part of the heat conducting portion 40 is in contact with the cold compressing portion 11, and the other part of the heat conducting portion 40 is arranged in the second cooling channel 62, so that the heat dissipation of the heat conducting portion 40 is separated from the heat dissipation of the heat removal device 30, thereby effectively improving an interior overall cooling efficiency of the depilator 100.

In this embodiment, the cool driving portion 50 drives the external cooling medium to flow into the depilator 100 with dual cooling channels, so that the external cooling medium flows into the first cooling channel 61 and the second cooling channel 62 which facilitates the external cooling medium to take the heat of the hair removal device 30 and the heat conducting portion 40 away at the same time. Specifically, the outer side of the second driving opening 52 is snap-coupled to the cooling bracket 60, so that the second driving opening 52 is sealed and abutted with the first cooling channel 61 and the second cooling channel 62, thereby reducing a resistance of the external cooling medium into the first cooling channel 61 and the second cooling channel 62.

The cool driving portion 50 drives the external cooling medium to flow through a power device, so that the external cooling medium can effectively take away the heat in the depilator 100 with the dual cooling channels. The second driving opening 52 is abutted with the first cooling channel 61 and the second cooling channel 62 which facilitates the cool driving portion 50 to use the power device to drive the external cooling medium to cool down the hair removal device 30 and the heat conducting portion 40 respectively from the two cooling channels, optimizes an internal structure of the depilator 100 with the dual cooling channels, and increases an internal heat dissipation efficiency of the depilator 100 with the dual cooling channels.

The illuminating portion 12 abuts against the bracket head 69, and one surface of the light source substrate 121 away from the lamp beads 122 abuts against the end surface of the bracket head 69, so that the illuminating portion 12 and the cooling bracket 60 are stable, and the light cover 13 is firmly coupled to the bracket head 69, to effectively cover the illuminating portion 12. The cooling bracket 60 is abutted with the second driving opening 52 at an opposite or adjacent side of the bracket head 69. The first cooling channel 61 and the second cooling channel 62 are abutted with the second driving opening 52 side by side, and the first cooling channel 61 and the second cooling channel 62 are separated by a partition.

In this embodiment, the hair removal device 30 emits light toward the cold compressing portion 11. The heat of the hair removal device 30 can be taken away by the external cooling medium of the first cooling channel 61. The external cooling medium of the first cooling channel 61 is directly obtained by the cool driving portion 50 sucking in the cooling medium of which external temperature is lowered, so as to effectively reduce the temperature of the hair removal device 30.

In this embodiment, the cold compressing portion 11 partially exposes the bracket head 69 so that the cold compressing portion 11 contacts the skin of the user. The cold compressing portion 11 is configured to contact the skin of the user and emit light. The cold compressing portion 11 has a cold compressing surface 111, and the cold compressing surface 111 is parallel to an outer end surface of the bracket head 69. The cold compressing portion 11 also has a heat conducting surface 112 that exposes the bracket head 69 and is arranged on a peripheral side of the cold compressing portion 11. The heat conducting surface 112 is attached to a part of the heat conducting portion 40, so that the heat of the cold compressing portion 11 is conducted from the heat conducting surface 112 to the heat conducting portion 40, thus, the cold compressing portion 11 achieves a cooling effect, and the cooling rate is accelerated.

Optionally, the cold compressing surface 111 is a flat surface, and the heat conducting surface 112 is a flat surface.

Optionally, the cold compressing surface 111 is an end surface of the cold compressing portion 11. The heat conducting surface 112 is a side surface of the cold compressing portion 11.

In this embodiment, a part of the heat conducting portion 40 is fixed to the bracket head 69 and is in contact with the heat conducting surface 112 of the cold compressing portion 11, and the other part of the heat conducting portion 40 extends from a part of the cooling bracket 60 away from the bracket head 69 into the second cooling channel 62, such that the external cooling medium in the second cooling channel 62 takes away the heat of the cold compressing portion 11, to reduce the temperature of the cold compressing portion 11 and reduce a burning sensation to the skin of the user caused by the light emitted by the cold compressing portion 11.

Furthermore, the heat conducting portion 40 includes a heat conducting plate 41 attached to the cold compressing portion 11 and a first heat sink assembly 42 and a second heat sink assembly 43 which are attached to the heat conducting plate 41. The heat conducting plate 41 is fixed on the cooling bracket 60. One end of the heat conducting plate 41 away from the cold compressing portion 11 covers the second cooling channel 62. The first heat sink assembly 42 is received in the second cooling channel 62 and contacts with a part of the heat conducting plate 41 covering the second cooling channel 62. The second heat sink assembly 43 is fixed on one side of the heat conducting plate 41 away from the first heat sink assembly 42, and the second heat sink assembly 43 is adjacent to the first guide opening 24, to increase an area of the heat conducting portion 40 contacting the external cooling medium, and increase a heat exchange rate between the heat conducting portion 40 and the external cooling medium, thereby increasing a cooling rate of the cold compressing portion 11 to the heat conducting portion 40.

In this embodiment, the heat conducting plate 41 is a flat plate. The heat conducting plate 41 adopts a structure in which two plates are laminated and sealed, and a heat conducting net is arranged between the two plates. A heat conducting medium is also arranged between the two plates of the heat conducting plate 41. The heat conducting net is fully contacted with the heat conducting medium, so that the contact area of the heat conducting medium contacting the two plates and the heat conducting net increases, and the heat conducting medium can quickly absorb the heat that the heat conductive plate 41 absorbs from the cold compressing portion 11, and the heat conducting medium can quickly conducts the heat to the first heat sink assembly 42, so that the heat can be dissipated by using the first heat sink assembly 42. The heat conducting plate 41 is a short heat conducting plate 41, that is, the distance between the place where the heat conducting plate 41 contacts the cold compressing portion 11 and the place where it contacts the first heat sink assembly 42 is short, so that the heat conducting plate 41 can conduct heat more quickly to the first heat sink assembly 42, and the first heat sink assembly 42 can quickly take away heat by using the cooling medium in the second cooling channel 62, so as to quickly cool down the cold compressing portion 11 and improve a cooling rate of the depilator 100.

Optionally, the two plates of the heat conducting plate 41 are both copper plates. The heat conducting net is a copper net with a capillary structure, so that the contact area of the heat conducting medium and the two plates is increased and more even, and the heat conduction efficiency of the heat conducting plate 41 is improved.

Optionally, a vacuum sealed cavity is provided between the two plates of the heat conducting plate 41, and the heat conducting medium and the heat conducting net are received in the sealed cavity.

Optionally, the heat conducting medium of the heat conducting plate 41 is cooling liquid, preferably water.

Optionally, the edges of the two plates of the heat conducting plate 41 are sealed and pressed together, so that the heat conducting plate 41 has a stable structure and prevents the heat from entering the heat conducting plate 41.

In this embodiment, the first heat sink assembly 42 includes a plurality of side-by-side heat sinks 421 attached to the heat conducting plate 41. The heat sinks 421 are configured to contact the heat conducting plate 41, to increase the contact area between the first heat sink assembly 42 and the heat conducting plate 41, and the heat conducting plate 41 can be configured to seal the second cooling channel 62, to avoid the leakage of the external cooling medium in the second cooling channel 62. The heat sinks 421 can quickly absorb the heat of the heat conducting plate 41. There is a cooling medium flow space between the plurality of heat sinks 421, and a cooling medium flow direction between the plurality of heat sinks 421 is consistent with an extending direction of the second cooling channel 62, so that the cooling medium in the second cooling channel 62 can quickly flow through the flow space between the plurality of heat sinks 421, such that the cooling medium in the second cooling channel 62 can quickly absorb the heat of the heat sinks 421 and take the heat away, thereby achieving effective heat dissipation of the heat conducting plate 41. The second heat sink assembly 43 and the first heat sink assembly 42 have substantially the same structure, which will not be repeated here.

Furthermore, the cooling bracket 60 includes a bottom shell 63 and a top shell 64 which is covered with the bottom shell 63. The heat conducting plate 41 is fixed on one side of the top shell 64 away from the bottom shell 63. A part of the cold compressing portion 11 is fixed between the bottom shell 63 and the top shell 64, and the other part of the cold compressing portion 11 passes through the top shell 64 to contact the heat conducting plate 41. The first cooling channel 61 is formed between the bottom shell 63 and the top shell 64. The second cooling channel 62 is formed between the bottom shell 63 and the heat conducting plate 41.

In this embodiment, the top shell 64 defines a gap 641 interconnecting with the second cooling channel 62. The heat conducting plate 41 seals and covers the gap 641, to achieve the heat conducting portion 40 to seal the gap 641, which facilitate a part of the heat conducting portion 40 to extend into the second cooling channel 62. The heat sinks 421 are completely received in the second cooling channel 62. A receiving groove 622 interconnecting with the first cooling channel 61 is also defined between the top shell 64 and the bottom shell 63. The cold compressing portion 11 is fixed in the receiving groove 622 so that the light from the hair removal device 30 can irradiate the cold compressing portion 11. The heat conducting surface 112 (see FIG. 6) extends out the receiving groove 622 from the top shell 64. The cold compressing surface 111 extends out the receiving groove 622 from the end surface of the bracket head 69, so that the cold compressing surface 111 is in contact with the skin of the user. The top shell 64 effectively supports the heat conducting plate 41, and the size of the heat conducting plate 41 is equivalent to the size of the top shell 64, making the internal structure of the depilator 100 more compact, which can effectively reduce the volume of the depilator 100 with the the dual cooling channels and is convenient to carry.

In this embodiment, the cooling bracket 60 defines a first transmitting opening 66 that interconnects with the first cooling channel 61 and the second cooling channel 62 and is away from the second driving opening 52. The first transmitting opening 66 is arranged between the top shell 64 and the bottom shell 63. The first transmitting opening 66 is disposed on a sidewall of the cooling bracket 60 adjacent to the cold compressing portion 11 and is away from the first driving opening 51.

Specifically, half of the first transmitting opening 66 is defined on the top shell 64 and the other half of the first transmitting opening 66 is defined on the bottom shell 63. The cooling bracket 60 defines the first transmitting opening 66 on a sidewall opposite to the cold compressing portion 11. The second driving opening 52 is abutted with the other sidewall of the cooling bracket 60. The cooling bracket 60 defines a second transmitting opening 65 on the other sidewall adjacent to the cold compressing portion 11. The second driving opening 52 of the shell 53 is abutted with the second transmitting opening 65. The first cooling channel 61 and the second cooling channel 62 are formed between the second transmitting opening 65 and the first transmitting opening 66. The cool driving portion 50 is located on one side of the cooling bracket 60 so that the second driving opening 52 blows the cooling medium to the second transmitting opening 65 and discharges the cooling medium from the first transmitting opening 66. The inner cooling medium of the cooling bracket 60 is blown in from one side of the cooling bracket 60 and blown out from the other side of the cooling bracket 60, so that the flow rate of the cooling medium in the first cooling channel 61 and the second cooling channel 62 increases, thereby increasing a heat dissipation efficiency.

In this embodiment, the cool driving portion 50, the cooling bracket 60, and the heat conducting portion 40 are all fixed in the receiving space 211. The second guide opening 25 is abutted with the first transmitting opening 66, such that the cooling medium entering into the cooling bracket 60 can be quickly discharged from the second guide opening 25, to prevent the cooling medium that has absorbed heat from flowing back into the cooling bracket 60. Of course, there may also be a certain distance between the second guide opening 25 and the first transmitting opening 66, so that the cooling medium discharged from the second guide opening 25 can be partially discharged from the first transmitting opening 66, and partially entering into the housing 21, so that the cooling medium can continue to cool down other components in the housing 21.

In this embodiment, the housing 21 protects the cool driving portion 50. The cool driving portion 50 directly sucks in the external cooling medium through the first guide opening 24, to reduce a resistance of the cool driving portion 50 driving the cooling medium to flow, and increase a flow rate of the cooling medium, and increase an internal heat dissipation rate of the depilator 100. Of course, there may also be a certain distance between the first driving opening 51 and the first guide opening 24, so that a part of the cooling medium entering from the first guide opening 24 can be quickly sucked into the cool driving portion 50, and is blown into the first cooling channel 61 and the second cooling channel 62, and the other part of the cooling medium can enter the housing 21 to cool down other components in the housing 21.

More specifically, the tail cover 213 defines a third guide opening 26, which can discharge the cooling medium in the housing 21, to facilitate the cooling medium which enters the housing 21 and is outside of the cooling bracket 60 to absorb the heat of other components in the housing 21, and discharge the heat from the third guide opening 26, so as to cool down the entire interior of the depilator 100 with the dual cooling channels.

Furthermore, referring to FIGS. 4, 5 and 6, the hair removal device 30 includes a lamp tube 31, a lamp tube holder 32, and a reflecting plate 33. The lamp holder 32 is fixed in the cooling bracket 60 and is close to the cold compressing portion 11. The lamp tube 31 and the reflecting plate 33 are fixed on the lamp tube holder 32. The reflecting plate 33 is located on one side of the lamp tube 31 away from the cold compressing portion 11. The reflecting plate 33 collects the light of the lamp tube 31 on the cold compressing portion 11.

In this embodiment, the lamp tube 31, the reflecting plate 33 and the lamp tube holder 32 are all located in the first cooling channel 61. The lamp tube 31, the reflecting plate 33 and the lamp tube holder 32 are all fixed in a part of the first cooling channel 61 adjacent to the cold compressing portion 11, to reduce a light path of the lamp tube 31, avoiding the heat of the emitted light conducting to more devices, and reducing the heat concentration in the first cooling channel 61. More specifically, the lamp tube holder 32 is fixed between the bottom shell 63 and the top shell 64, so that the lamp tube holder 32 and the cooling bracket 60 have a stable structure. The lamp tube 31, the reflecting plate 33 and the lamp tube holder 32 are adjacent to the first transmitting opening 65, so that the cooling medium which absorbs the heat of the lamp tube 31, the reflecting plate 33 and the lamp tube holder 32 can be discharged from the first transmitting opening 65 immediately, thereby effectively reducing the heat of the lamp tube 31, the reflecting plate 33 and the lamp tube holder 32. The reflecting plate 33 condenses and reflects the light of the lamp tube 31 to increase a light concentration of the cold compressing portion 11. The two ends of the reflecting plate 33 have openings, so that the cooling medium flows from one opening of the reflecting plate 33 to the other opening, and the external cooling medium contacts the peripheral side of the lamp tube 31 to form convection, which effectively cools the lamp tube 31. The two openings of the reflection plate 33 are respectively adjacent to the first transmitting opening 66 and the second transmitting opening 65 so that the cooling medium in the first cooling channel 61 quickly flows through an inner side of the reflection plate 33 to improve a heat dissipation efficiency of the lamp tube 31.

Furthermore, the depilator 100 with the dual cooling channels further includes a control device 70. The control device 70 includes a circuit board 71, a processor, and a capacitor 73. The processor is located on the circuit board 71. The capacitor 73 is electrically coupled to the circuit board 71. The circuit board 71 is electrically coupled to the cold compressing portion 11 and the hair removal device 30.

In this embodiment, the hair removal device 30 is electrically coupled to the control device 70. The control device 70 can provide power to the hair removal device 30 and control an operation of the hair removal device 30, so that the depilator 100 can be used without plugging in an external circuit, or it can be used to directly connect an external power source, such as a dry capacitor or an energy storage capacitor, which is convenient for storage and carrying, and can be used outside. The control device 70 can also be coupled to an external circuit for charging, and can control the start and stop, power regulation, thermal protection, etc of the depilator 100 with dual cooling channels.

It is understandable that the heat inside the fuselage of the traditional depilator 100 is large at present, which is likely to cause short-circuit, burnout, explosion and other dangers to the components inside the fuselage of the depilator 100. However, the heat conducting plate 41 of the present disclosure uses the cooling medium in the second cooling channel 62 to effectively cool down the cold compressing portion 11. The hair removal device 30 uses the cooling medium in the first cooling channel 61 to effectively dissipate heat, so that the cold compressing portion 11 can effectively cold compress the skin of the user with high comfort and no skin damage, and the temperature of the hair removal device 30 is effectively reduced. The cooling medium can also be configured to cool down other internal components of the depilator 100 with dual cooling channels, so that the entire body of the depilator 100 with dual cooling channels is cooled, preventing the internal temperature of the depilator 100 with dual cooling channels from being too high and causing harm. Specifically, the control device 70 of the depilator 100 with dual cooling channels of the present disclosure generates heat when it is working. The cool driving portion 50 can also drive the external cooling medium to flow into the housing 21 to contact the control device 70, the heat of the control device 70 can be taken away by using external cooling medium, to realize the rapid cooling of the internal components of the depilator 100 with dual cooling channels and the control device 70. Excessive heat in the receiving space 211 of the depilator 100 with dual cooling channels can be avoided. The hair removal device 30, the control device 70 and other devices can be prevented from being short-circuited, burned, and exploded.

In this embodiment, the control device 70 is arranged inside the housing 21, and is optionally arranged on a part of the cooling bracket 60 away from the cold compressing portion 11. The control device 70 is arranged on one side of the hair removal device 30 away from the cold compressing portion 11, that is, one side of the hair removal device 30 away from the human skin. Through such a design, the contact range of the external cooling medium allowed to be contacted in the receiving space 211 is expanded to achieve an effect of overall internal cooling of the housing 21.

In this embodiment, the control device 70 includes the circuit board 71 fixed on the inner side of the lower housing 23, the processor fixed on the circuit board 71, and the capacitor 73 fixed on the inner side of the lower housing 23. The circuit board 71 is fixed in the part of the housing 21 close to the cooling bracket 60. The processor 72 processes the electrical signals of the hair removal device 30 and the illuminating portion 12, so as to control the hair removal device 30 to operate. The capacitor 73 provides power to the illuminating portion 12, the hair removal device 30, the cool driving portion 50, the circuit board 71, and the processor.

Furthermore, the cold compressing portion 11 includes a cold compressing member 119 and a cooling member 118 for cooling the cold compressing member 119. The cold compressing member 119 is configured to contact the skin of the user and perform cold compresses. The cooling element 118 includes a cooling surface 117 adhering to the cold compressing member 119. The cooling surface 117 is disposed opposite to the heat conducting surface 112. The heat conducting plate 41 is attached to the heat conducting surface 112 to absorb heat from the heat conducting surface 112.

In this embodiment, the lamp tube 31, the cooling member 118, and the light source substrate 121 are all electrically coupled to the circuit board 71. The cold compressing member 119 is clamped on the cooling bracket 60, so that the cooling member 118 is firmly attached to between the cold compressing member 119 and the cooling bracket 60, to facilitate the heat conducting plate 41 to contact with the cooling member 118. The cooling member 118 is closely attached to the cold compressing member 119, to cool the cold compressing member 119. A filter is also provided between the cold compressing member 119 and the lamp tube 31. The filter is configured to filter out some harmful light emitted from the lamp tube 31, so that the light emitted by the lamp tube 31 can safely and effectively remove hair on the skin of the user. The heat of the lamp tube 31 is conducted to the cold compressing member 119, and the reflecting plate 33 is arranged on the side of the lamp 31 away from the cold compressing member 119, so that the light emitted by the lamp 31 is concentrated on the cold compressing member 119.

Preferably, the cold compressing member 119 is made of crystal materials, and specifically can be sapphire, K9 glass, crystal glass, and any materials that satisfies light-transmitting crystals, and optionally sapphire materials.

It can be understood that since the cold compressing member 119 is made of sapphires, the cold compressing member 119 can also be used as a light outlet. When the lamp tube 31 emits light, the sapphire has strong thermal conductivity, so that the cooling element 118 and the cold compressing member 119 can produce heat exchange efficiently, so as to achieve the best cooling effect. Optionally, the cold compressing member 119 may be a circular plate or a rectangular plate, which is not limited here. The side of the cold compressing member 119 away from the lamp tube 31 is in contact with the human body, and the contact surface may be a curved surface or a flat surface, preferably a flat surface.

In this embodiment, the lamp tube 31 may be an IPL lamp tube, which is located on one side of the cold compressing member 119 away from the human body. The light emitted by the lamp tube 31 is emitted to the skin of the user through the cold compressing member 119. The color of the light emitted by the lamp tube 31 is not limited, and can be colored light, composite light, etc. The specific wavelength and frequency are determined according to the usage.

In this embodiment, the depilator 100 with dual cooling channels includes a skin detection part. The skin detection part can be integrated in the cold compressing member 119. The skin detection part uses a touch detection principle to electrically connect the circuit board 71. When the cold compressing member 119 touches the skin, the internal preset capacitor detection device simultaneously detects whether the depilator 100 with dual cooling channels actually touches the skin, reducing users safety problems caused by misoperations.

In this embodiment, the shape of the reflecting plate 33 is not limited, and only the light of the lamp tube 31 is concentrated in the direction of the cold compressing member 119. Optionally, the reflecting plate 33 is U-shaped, and the opening of the reflecting plate 33 set toward the cold compressing member 119. The lamp tube 31 is located at a center of the U-shaped opening of the reflecting plate 33. In addition to concentrating light, it can also prevent the lamp tube 31 from radiating heat to other places during operation.

In this embodiment, the cooling member 118 can optionally be a cooling element having a semiconductor cooling method.

It can be understood that due to the special principle of the depilator 100 with dual cooling channels adopts 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 119 touches the skin, in order to prevent the light from causing the user to burn for pain, a cooling structure needs to be provided in the body of the depilator 100 with dual cooling channels. No matter how the temperature is lowered, heat will be generated during the heat exchange. The cooling member 118 is close to the heat conducting plate 41, making the cold compressing member 119 fast cooling. In addition to the heat generated by the cooling member 118, the plurality of heating devices are also arranged in the receiving space 211, and the external cooling medium in the housing 21 can effectively cool the plurality of heating devices.

It can be understood that the external cooling medium is sucked in from the first guide opening 24, enters the first driving opening 51, and then passes through the second driving opening 52 to the cooling bracket 60, and then passes through the hair removal device 30 and the first heat sink assembly 42. The heat of the lamp tube 31 is decreased, and the heat of the heat conducting plate 41 and the cold compressing portion 11 are decreased. Part of the cooling medium enters the housing 21, flows through the circuit board 71, the processor and the capacitor 73, and is finally discharged from the third guide opening 26, so that the area where the external cooling medium passes through is cooled.

Furthermore, the housing 21 further defines a fourth guide opening 27 adjacent to the first guide opening 24. The fourth guide opening 27 is directly opposite to the heat conducting portion 40. A cooling channel is formed between the fourth guide opening 27 and the first guide opening 24, so that the heat of the heat conducting portion 40 is taken away by the external cooling medium in the cooling channel. The fourth guide opening 27 and the first guide opening 24 are arranged on a same side of the housing 21. The fourth guide opening 27 and the first guide opening 24 are located at one side of the first guide opening 24 close to the head portion 10. The fourth guide opening 27 can quickly conduct the heat of the heat conducting portion 40 away, so as to achieve a rapid cooling of the heat conducting portion 40.

Based on the above-mentioned separation of the first cooling channel 61 and the second cooling channel 62 in the depilator 100 with dual cooling channels, in some embodiments, the heat dissipation method of the depilator 100 may not use fan air cooling, or other external cooling channels may be used. The cooling medium, such as water, coolant, etc., only needs the external medium to take away the heat of the cooling channel.

A contact end surface of the cold compressing portion 11 with the skin and an exposed end surface of the skin detection part are located on the same side, so that when the skin is irradiated and hair removed, the cold compressing member 119 is in contact with the irradiated area of the skin to cool the irradiated skin, reducing the burning sensation of the irradiated skin. The cold compressing member 119 can be close to zero temperature. The skin near a light exit infinitely close to the freezing point is truly achieved, which can reduce a burning sensation of the skin, and will not cause a skin damage by a short-term contact.

In some embodiments, a depilator 100 includes a luminous body, and the structural features described in all the above embodiments are used.

Those skilled in the art should also understand that if all or part of the components of the depilator 100 with dual cooling channels of the present disclosure are combined by means of fusion, physical connection, etc., such as the moving positions of the components in the hair removal device 30; or they are integrated or detachable design; and the replacement of the number of features, and the change of the feature shape that is not used as a function. Any combined component can form an equipment/device with a specific function. Using such the equipment/device to replace the corresponding component of the present disclosure also falls within the protection scope of the present disclosure.

Compared with the prior art, the depilator 100 with dual cooling channels of the present disclosure has the following advantages.

1. The head portion 10 includes the cold compressing portion 11 and the illuminating portion 12 arranged around the cold compressing portion 11. The illuminating portion 12 is configured to emit light for caring the skin of the user. The hair removal device 30 is in directly contact with the cold compressing portion 11, and is configured to emit light to the cold compressing portion 11, so that the cold compressing portion 11 can emit light to irradiate the hair follicles of the skin of the user. By using the light to penetrate the skin to irradiate the hair follicles for hair removal, the depilator 100 has both functions of hair removal and skin care.

2. The cooling bracket 60 defines the first cooling channel 61 and the second cooling channel 62. Both the first cooling channel 61 and the second cooling channel 62 are abutted with the second driving opening 52 of the cool driving portion 50. The hair removal device 30 is fixed in the first cooling channel 61. A part of the heat conducting portion 40 is in contact with the cold compressing portion 11, and the other part of the heat conducting portion 40 is arranged in the second cooling channel 62. Thus, the heat dissipation of the heat conducting portion 40 and the heat dissipation of the hair removal device 30 are achieved to be separated, thereby effectively improving an overall internal cooling efficiency of the decoder 100.

3. The depilator 100 with dual cooling channels uses a composite structure of the heat conducting plate 41. The heat conducting plate 41 uses two laminated plates, a heat conduction medium and a heat conduction net sealed between the two plates to increase a heat conduction effectively of the heat conducting plate 41. The heat conducting plate 41 absorbs the heat of the cold compressing portion 11, so that the heat of the cold compressing portion 11 is rapidly reduced. The heat conducting plate 41 is made of copper materials, which increases the heat conduction efficiency of the heat conducting plate 41, can effectively and quickly absorb heat, and effectively and quickly dissipate heat.

4. In the past, only a sealed cavity was configured to separately protect the cooling member 118 of the cold compressing portion 11 to ventilate it. The hair removal device 30 and the control device 70, which also generate heat, were not considered, especially when used for a long time, the heat of the hair removal device 30 and the lamp tube 31 will be very high, so the cooling effect is not complete. The depilator 100 with dual cooling channels of the present disclosure separately simultaneously cools the cold compressing portion 11 and the hair removal device 30, so that the overall cooling effect is greatly improved, and the overall temperature in the body of the depilator 100 with dual cooling channels is effectively reduced.

5. 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 water pumps, water extraction or cooling liquids, etc.

6. The first guide opening 24 is arranged on one side of the head portion 10, so that the cooling medium can be discharged quickly, and the heat dissipation efficiency of the cold compressing portion 11 and the hair removal device 30 is improved. The second guide opening 25 is arranged at a part of the housing 21 adjacent to the hair removal device 30 and the cold compressing portion 10, and facilitates the simultaneous removal of heat from the hair removal device 30 and the heat conducting portion 40, thereby increasing the heat dissipation efficiency. The third guide opening 26 is arranged at a tail end of the depilator 100 with dual cooling channels away from the cold compressing portion 11, so that the cooling medium flows in the depilator 100 with dual cooling channels and is discharged after a longer distance, and the heat flowing through the control device 70 is discharged, which can reduce the heat of the control device 70.

7. The cold compressing member 119 is exposed from the head portion 10 of the housing 21 and actually contacts the human skin, so that the user can feel a cold compress effect of the cold compressing member 119 during a cold compressing process by using the depilator 100 with dual cooling channels, thereby the user's strong pain sensation due to the heat of the depilator 100 with dual cooling channels is reduced.

8. The cold compressing member 119 is made of crystal materials, which can be made of sapphire. Sapphire has strong thermal conductivity, which can reduce the heat of the light emitted by the depilator 100 with dual cooling channels while maintaining the light transmittance.

9. The cooling element 118 can be a semiconductor cooling chip, which can effectively improve the cooling effect of the depilator 100 with dual cooling channels.

10. The depilator 100 with dual cooling channels is equipped with the skin detection part. When the cold compressing portion 11 is in contact with the skin, the skin detection part will detect whether the machine actually touches the skin, which can reduce the safety problems caused by the user due to misoperation, and improve the working efficiency of the depilator 100 with dual cooling channels.

The above are the implementation modes of the embodiments of the present disclosure. It should be pointed out that for those of ordinary skill in the art, several improvements and modifications can be made without departing from the principle of the embodiments of the present disclosure, and these improvements and modifications are also treated as the scope of protection of the present disclosure.
