A receiving groove <NUM> interconnecting with the first cooling channel <NUM> is also defined between the top shell <NUM> and the bottom shell <NUM>. The cold compressing portion <NUM> is fixed in the receiving groove <NUM> so that the light from the hair removal device <NUM> can irradiate the cold compressing portion <NUM>. The heat conducting surface <NUM> (see <FIG> ) extends out the receiving groove <NUM> from the top shell <NUM>. The cold compressing surface <NUM> extends out the receiving groove <NUM> from the end surface of the bracket head <NUM>, so that the cold compressing surface <NUM> is in contact with the skin of the user. The top shell <NUM> effectively supports the heat conducting plate <NUM>, and the size of the heat conducting plate <NUM> is equivalent to the size of the top shell <NUM>, making the internal structure of the depilator <NUM> more compact, which can effectively reduce the volume of the depilator <NUM> with the the dual cooling channels and is convenient to carry.

In this embodiment, the cooling bracket <NUM> defines a first transmitting opening <NUM> that interconnects with the first cooling channel <NUM> and the second cooling channel <NUM> and is away from the second driving opening <NUM>. The first transmitting opening <NUM> is arranged between the top shell <NUM> and the bottom shell <NUM>. The first transmitting opening <NUM> is disposed on a sidewall of the cooling bracket <NUM> adjacent to the cold compressing portion <NUM> and is away from the first driving opening <NUM>.

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

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

In this embodiment, the housing <NUM> protects the cool driving portion <NUM>. The cool driving portion <NUM> directly sucks in the external cooling medium through the first guide opening <NUM>, to reduce a resistance of the cool driving portion <NUM> 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 <NUM>. Of course, there may also be a certain distance between the first driving opening <NUM> and the first guide opening <NUM>, so that a part of the cooling medium entering from the first guide opening <NUM> can be quickly sucked into the cool driving portion <NUM>, and is blown into the first cooling channel <NUM> and the second cooling channel <NUM>, and the other part of the cooling medium can enter the housing <NUM> to cool down other components in the housing <NUM>.

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

Furthermore, referring to <FIG> and <FIG> , the hair removal device <NUM> includes a lamp tube <NUM>, a lamp tube holder <NUM>, and a reflecting plate <NUM>. The lamp holder <NUM> is fixed in the cooling bracket <NUM> and is close to the cold compressing portion <NUM>. The lamp tube <NUM> and the reflecting plate <NUM> are fixed on the lamp tube holder <NUM>. The reflecting plate <NUM> is located on one side of the lamp tube <NUM> away from the cold compressing portion <NUM>. The reflecting plate <NUM> collects the light of the lamp tube <NUM> on the cold compressing portion <NUM>.

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

Furthermore, the depilator <NUM> with the dual cooling channels further includes a control device <NUM>. The control device <NUM> includes a circuit board <NUM>, a processor, and a capacitor <NUM>.

The control device <NUM> 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 <NUM> with dual cooling channels.

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

In this embodiment, the control device <NUM> is arranged inside the housing <NUM>, and is optionally arranged on a part of the cooling bracket <NUM> away from the cold compressing portion <NUM>. The control device <NUM> is arranged on one side of the hair removal device <NUM> away from the cold compressing portion <NUM>, that is, one side of the hair removal device <NUM> 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 <NUM> is expanded to achieve an effect of overall internal cooling of the housing <NUM>.

In this embodiment, the control device <NUM> includes the circuit board <NUM> fixed on the inner side of the lower housing <NUM>, the processor fixed on the circuit board <NUM>, and the capacitor <NUM> fixed on the inner side of the lower housing <NUM>. The circuit board <NUM> is fixed in the part of the housing <NUM> close to the cooling bracket <NUM>. The processor <NUM> processes the electrical signals of the hair removal device <NUM> and the illuminating portion <NUM>, so as to control the hair removal device <NUM> to operate. The capacitor <NUM> provides power to the illuminating portion <NUM>, the hair removal device <NUM>, the cool driving portion <NUM>, the circuit board <NUM>, and the processor.

Furthermore, the cold compressing portion <NUM> includes a cold compressing member <NUM> and a cooling member <NUM> for cooling the cold compressing member <NUM>. The cold compressing member <NUM> is configured to contact the skin of the user and perform cold compresses. The cooling element <NUM> includes a cooling surface <NUM> adhering to the cold compressing member <NUM>. The cooling surface <NUM> is disposed opposite to the heat conducting surface <NUM>. The heat conducting plate <NUM> is attached to the heat conducting surface <NUM> to absorb heat from the heat conducting surface <NUM>.

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

Preferably, the cold compressing member <NUM> 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 <NUM> is made of sapphires, the cold compressing member <NUM> can also be used as a light outlet. When the lamp tube <NUM> emits light, the sapphire has strong thermal conductivity, so that the cooling element <NUM> and the cold compressing member <NUM> can produce heat exchange efficiently, so as to achieve the best cooling effect. Optionally, the cold compressing member <NUM> may be a circular plate or a rectangular plate, which is not limited here. The side of the cold compressing member <NUM> away from the lamp tube <NUM> 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 <NUM> may be an IPL lamp tube, which is located on one side of the cold compressing member <NUM> away from the human body. The light emitted by the lamp tube <NUM> is emitted to the skin of the user through the cold compressing member <NUM>. The color of the light emitted by the lamp tube <NUM> 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 <NUM> with dual cooling channels includes a skin detection part. The skin detection part can be integrated in the cold compressing member <NUM>. The skin detection part uses a capacitor touch detection principle to electrically connect the circuit board <NUM>. When the cold compressing member <NUM> touches the skin, the internal preset capacitor detection device simultaneously detects whether the depilator <NUM> with dual cooling channels actually touches the skin, reducing users safety problems caused by misoperations.

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

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

It can be understood that due to the special principle of the depilator <NUM> 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 <NUM> touches the skin, in order to prevent the light from causing the user to bum for pain, a cooling structure needs to be provided in the body of the depilator <NUM> with dual cooling channels. No matter how the temperature is lowered, heat will be generated during the heat exchange. The cooling member <NUM> is close to the heat conducting plate <NUM>, making the cold compressing member <NUM> fast cooling. In addition to the heat generated by the cooling member <NUM>, the plurality of heating devices are also arranged in the receiving space <NUM>, and the external cooling medium in the housing <NUM> 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 <NUM>, enters the first driving opening <NUM>, and then passes through the second driving opening <NUM> to the cooling bracket <NUM>, and then passes through the hair removal device <NUM> and the first heat sink assembly <NUM>. The heat of the lamp tube <NUM> is decreased, and the heat of the heat conducting plate <NUM> and the cold compressing portion <NUM> are decreased. Part of the cooling medium enters the housing <NUM>, flows through the circuit board <NUM>, the processor and the capacitor <NUM>, and is finally discharged from the third guide opening <NUM>, so that the area where the external cooling medium passes through is cooled.

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

Based on the above-mentioned separation of the first cooling channel <NUM> and the second cooling channel <NUM> in the depilator <NUM> with dual cooling channels, in some embodiments, the heat dissipation method of the depilator <NUM> 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 <NUM> 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 <NUM> 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 <NUM> 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.
