Description

Technical Field

[0001] This application relates to the field of hair removal equipment technology, and more specifically, to a cooling drive and a hair removal device having the cooling drive. Background Technology

[0002] Hair removal devices are a type of photon cosmetic technology developed based on laser technology. Currently, most hair removal or skin whitening / rejuvenation devices use a light-emitting mechanism to emit discontinuous intense pulses of light to treat the user's skin.

[0003] When a hair removal device is in operation, the light source in the light-emitting mechanism emits a large amount of heat, causing the temperature of the part of the device that comes into contact with the human body at the light outlet to rise sharply, which can easily burn the user. Therefore, existing technologies incorporate a cooling component at the light outlet to lower the temperature of the part of the device that comes into contact with the human body, providing a cooling sensation and reducing the burning sensation during use. At the same time, to ensure effective heat dissipation, a heat dissipation mechanism is also needed to cool the light-emitting mechanism. However, the existing structure is complex and not conducive to the miniaturization of hair removal devices. Summary of the Invention

[0007] The housing has a receiving space, and the fan blades are disposed in the receiving space to drive airflow. The housing includes a heat sink, at least a portion of which is attached to the light-emitting mechanism and is located in the direction of airflow.

[0008] Furthermore, the top of the heat sink has a fitting portion that fits into the light-emitting mechanism, and the bottom of the heat sink has a first heat dissipation fin. The fan blade is located between the fitting portion and the first heat dissipation fin, and the first heat dissipation fin is located in the direction of airflow.

[0009] Furthermore, the surface of the heat sink is coated with a heat dissipation layer, which is disposed on the side of the heat sink away from the light-emitting mechanism.

[0010] Furthermore, the heat dissipation component includes a first heat transfer plate and a second heat transfer plate, with a capillary core layer and a thermally conductive medium filling the space between the first heat transfer plate and the second heat transfer plate.

[0011] To address the aforementioned technical problems, this application provides a hair removal device, characterized in that it includes a housing, a light-emitting mechanism, and a cooling drive component as described in any of the above-mentioned solutions. The housing has an air inlet, an air outlet, and a light outlet. The light-emitting mechanism and the cooling drive component are both assembled inside the housing. The cooling drive component is disposed between the air inlet and the air outlet and is used to drive airflow from the air inlet to the air outlet. The light-emitting mechanism is connected to the heat sink and is disposed between the cooling drive component and the light outlet.

[0012] Furthermore, the light-emitting mechanism includes a light source and a reflector. The light source is fixed between the reflector and the light outlet. A fitting portion is formed on the top of the heat sink. The side of the reflector away from the light source is fitted with the fitting portion. The shape of the fitting portion is adapted to the reflector.

[0013] Furthermore, thermally conductive silicone grease is provided at the contact point between the heat sink and the light-emitting mechanism.

[0014] Furthermore, the hair removal device also includes a light-transmitting crystal and a cooling mechanism. The light-transmitting crystal is mounted at the light outlet of the outer casing of the device, and the cooling mechanism is mounted inside the outer casing of the device and in contact with the light-transmitting crystal. The cooling mechanism is located on the air inlet side of the cooling drive component.

[0015] Furthermore, the cooling mechanism includes a cooling chip and a heat-conducting component. The cooling chip is connected to the heat-conducting component and is in contact with the light-transmitting crystal.

[0016] Furthermore, the heat-conducting component includes a heat sink, a heat pipe, and a second heat dissipation fin. One side of the heat sink is in contact with the cooling chip, and the other side is connected to the heat pipe. The end of the heat pipe away from the heat sink is connected to the second heat dissipation fin, which is located on the air inlet side of the cooling drive component.

[0017] Compared with the prior art, the embodiments of this application have the following main advantages:

[0018] 1. This application utilizes a heat sink that is attached to the light-emitting mechanism to conduct heat generated from the light-emitting mechanism. The fan blades in the cooling drive unit rotate, driving airflow. The heat sink is located in the direction of airflow, allowing the airflow to pass through it and carry away heat, thereby accelerating heat dissipation from the light-emitting mechanism. This application integrates the heat sink as part of the housing of the cooling drive unit. This ensures that heat is carried away by the airflow in a timely manner, effectively improving heat dissipation efficiency. Furthermore, it simplifies the structure for heat dissipation of the light-emitting mechanism. The housing of the cooling drive unit directly contacts the light-emitting mechanism for heat conduction, eliminating the need for a separate heat-conducting structure for the light-emitting mechanism.

The structure of each part of the hair removal device is more compact, and it can be made smaller and lighter. Attached Figure Description

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] This application provides a cooling drive 100 for dissipating heat from the light-emitting mechanism. (See attached document.) Figures 1 to 3The cooling drive unit 100 includes a housing and a fan blade 120; the housing has a receiving space, and the fan blade 120 is disposed in the receiving space for driving airflow. The housing includes a heat sink 110, at least a portion of which is attached to the light-emitting mechanism and is located in the direction of airflow.

[0034] Understandably, the working principle of the cooling drive unit 100 is as follows:

[0035] The fan blade 120 is located inside the housing. The heat sink 110 is part of the housing that constitutes the cooling drive component. The heat sink 110 is attached to the light-emitting mechanism, so that the heat generated by the light-emitting mechanism is conducted to the heat sink 110. When the fan blade 120 drives the airflow, the airflow flows through the heat sink 110 to carry away the heat on the heat sink 110, thereby realizing the heat dissipation of the light-emitting mechanism.

[0036] Compared with the prior art, the cooling drive 100 has at least the following technical advantages:

[0037] In this embodiment, the heat sink 110 is attached to the light-emitting mechanism to conduct heat generated from the light-emitting mechanism. The fan blades 120 in the cooling drive unit rotate to drive airflow. The heat sink 110 is located in the direction of airflow, allowing the airflow to pass through the heat sink 110 and carry away the heat on the heat sink 110, thereby accelerating the heat dissipation of the light-emitting mechanism by the heat sink 110. In this application, the heat sink 110 is set as part of the housing of the cooling drive unit. On the one hand, it can ensure that the heat on the heat sink 110 can be carried away by the airflow in time, effectively improving the heat dissipation efficiency. On the other hand, it simplifies the structure for heat dissipating the light-emitting mechanism. The housing of the cooling drive unit directly contacts the light-emitting mechanism for heat conduction, so there is no need to set up a separate heat-conducting structure for the light-emitting mechanism, reducing the space occupied when heat dissipating the light-emitting mechanism, which is conducive to the miniaturization of the hair removal device.

[0038] In one embodiment, a fitting portion 111 is formed on the top of the heat sink 110, which is fitted to the light-emitting mechanism. A first heat dissipation fin 112 is formed on the bottom of the heat sink 110. A fan blade 120 is located between the fitting portion 111 and the first heat dissipation fin 112, and the first heat dissipation fin 112 is located in the airflow direction. Specifically, the heat generated by the light-emitting mechanism is conducted to the heat sink 110 through the fitting portion 111. The first heat dissipation fin 112 is located in the airflow direction, and the airflow passing through the first heat dissipation fin 112 can carry away the heat of the heat sink 110. There are multiple first heat dissipation fins 112, which are arranged perpendicular to the airflow direction to increase the heat transfer area between the heat sink 110 and the airflow and improve the heat dissipation efficiency of the heat sink 110. In this embodiment, the bonding portion 111 and the first heat dissipation fin 112 are connected by a flat plate. The bonding portion 111, the first heat dissipation fin 112, and the flat plate are integrally formed, and the fan blade 120 is located on one side of the flat plate. It should be noted that in this application, "multiple" refers to a quantity of at least two.

[0039] In this embodiment, the housing of the cooling drive unit 100 also includes a front cover 130, which is connected to the heat sink 110 to form an accommodating space. The fan blade 120 is located between the front cover 130 and the heat sink 110. The front cover 130 is provided with a ventilation opening, which is correspondingly arranged with the fan blade 120. When the fan blade 120 is started, it drives the airflow to enter the interior of the cooling drive unit 100 through the ventilation opening. After passing through the fan blade 120, the airflow flows to the heat sink 110. The heat sink 110 blocks the direction of the airflow, so that the airflow first flows perpendicular to the direction of the heat sink 110 under the drive of the fan blade 120. After reaching the heat sink 110, the direction of the airflow changes to flow along the direction of the heat sink 110, so that the airflow is discharged from the gap between the multiple first heat sink fins 112 to the outside of the cooling drive unit 100, so that the airflow can carry away the heat on the heat sink 110.

[0040] In one embodiment, the surface of the heat sink 110 is coated with a heat dissipation layer (not shown in the figure), and the heat dissipation layer is disposed on the side of the heat sink 110 away from the light-emitting mechanism. In this embodiment, the heat dissipation layer is a graphene coating. In other embodiments, the heat dissipation layer may also be made of a material with high thermal conductivity. By coating the heat sink 110 with a heat dissipation layer, the heat dissipation efficiency can be further improved, allowing the heat generated by the light-emitting mechanism to be quickly dissipated through the heat sink 110.

[0041] In one embodiment, the heat sink 110 includes a first heat transfer plate (not shown) and a second heat transfer plate (not shown), with a capillary core layer and a thermally conductive medium filling the space between the first and second heat transfer plates. The heat sink 110, composed of the first heat transfer plate, the second heat transfer plate, and the capillary core layer and thermally conductive medium filling the space between the first and second heat transfer plates, has high thermal conductivity and can effectively absorb and conduct the heat generated by the light-emitting mechanism. In other embodiments, the heat sink 110 can also be a metal plate or a vacuum chamber heat exchanger (VC plate), or other heat sinks with good thermal conductivity.

[0042] Based on the aforementioned cooling drive 100, this application embodiment also provides a hair removal device, see reference. Figures 4 to 9 The hair removal device includes a main body shell, a light-emitting mechanism, and the aforementioned cooling drive component 100. The main body shell has an air inlet 201, an air outlet 202, and a light outlet 203. The light-emitting mechanism and the cooling drive component 100 are both assembled inside the main body shell. The cooling drive component 100 is located between the air inlet 201 and the air outlet 202. The cooling drive component 100 is used to drive the airflow from the air inlet 201 to the air outlet 202. The light-emitting mechanism is connected to the heat sink 110 and is located between the cooling drive component 100 and the light outlet 203.

[0043] Understandably, the working principle of the cooling drive unit 100 is as follows:

[0044] When the light-emitting mechanism is working, it generates discontinuous strong pulse light and emits it through the light outlet 203. The fan blades 120 in the cooling drive unit 100 drive the airflow from the air inlet 201 to the air outlet 202. During the flow of the airflow, it passes through the heat sink 110 of the cooling drive unit 100. After the heat sink 110 absorbs the heat of the light-emitting mechanism, the heat is carried away by the airflow flowing through the heat sink 110, thereby achieving heat dissipation of the light-emitting mechanism.

[0045] Compared with the prior art, the cooling drive 100 has at least the following technical advantages:

[0046] This application integrates the heat sink 110 in the cooling drive 100 with the light-emitting mechanism, so that the heat sink 110 simultaneously serves as a housing and heat transfer and dissipation functions. The fan blades 120 in the cooling drive 100 can accelerate the heat dissipation of the heat sink 110, ensuring the heat dissipation efficiency of the light-emitting mechanism when the hair removal device is working. At the same time, the hair removal device structure assembled using the cooling drive 100 provided in this application is simpler, eliminating the need for a heat conduction structure for the light-emitting mechanism. The various parts of the hair removal device are more compact, making it smaller and lighter.

[0047] Specifically, the ventilation openings on the cooling drive unit correspond to the air inlet 201 on the hair removal device. Airflow enters the hair removal device through the air inlet 201, and then enters the cooling drive unit through the ventilation openings. Heat from the heat sink 110 section through which the airflow passes is carried away by the airflow. After exiting the cooling drive unit, the airflow exits through the air outlet 202 and is then discharged outside the hair removal device. In this embodiment, the light outlet 203 is located at the top of the outer casing, and the air outlet 202 is located at the bottom of the outer casing, allowing the hot airflow to exit from the bottom of the hair removal device without affecting normal user operation.

[0048] In some embodiments, the bottom of the heat sink and the bottom of the front cover 130 may also extend to the air outlet 202 of the entire housing to guide airflow through the air outlet 202 and prevent hot airflow from flowing through other components of the hair removal device and carrying heat to those components.

[0049] In one embodiment, see Figures 5 to 9 The light-emitting mechanism includes a light source and a reflector 320. The light source is fixed between the reflector 320 and the light outlet 203. A fitting portion 111 is formed on the top of the heat sink 100. The side of the reflector 320 away from the light source is fitted with the fitting portion 111, and the shape of the fitting portion 111 is adapted to the reflector 320. In this embodiment, the reflector 320 is an arc-shaped reflector with a groove. The light source is installed in the groove of the arc-shaped reflector to reflect the light emitted by the light source to the light outlet 203, thereby improving the light utilization rate. During the reflection process, a large amount of light will shine on the reflector, causing the arc-shaped reflector to accumulate a large amount of heat, resulting in a sharp increase in the temperature of the light-emitting mechanism. This application, by fitting the fitting portion 111 of the heat sink 110 with the reflector 320, can promptly conduct the heat on the reflector 320 to the heat sink 110, allowing the heat of the reflector to be conducted away, thereby achieving heat dissipation of the light-emitting mechanism. In this embodiment, the shape of the fitting portion 111 is adapted to the reflector 320, which increases the heat transfer area between the fitting portion 111 and the reflector 320, thereby improving the heat dissipation effect. Specifically, the reflector 320 is an arc-shaped reflector with a groove, and the fitting portion 111 of the heat dissipation component 110 is an arc-shaped structure adapted to the arc-shaped reflector. Of course, in other embodiments, the reflector 320 can also be a straight surface, a curved surface, or other irregular structures.

[0050] In one embodiment, thermally conductive silicone grease is provided at the contact point between the heat sink 110 and the light-emitting mechanism. Specifically, the thermally conductive silicone grease is disposed between the contact portion 111 and the reflector 320, which can improve the thermal conductivity of the heat sink 110.

[0051] In one embodiment, the hair removal device includes a light-transmitting crystal 400 and a cooling mechanism. The light-transmitting crystal 400 is mounted at the light outlet 203 of the outer casing 200, and the cooling mechanism is mounted inside the outer casing and in contact with the light-transmitting crystal 400. The cooling mechanism is located on the air inlet side of the cooling drive unit 100. Specifically, the light-transmitting crystal 400 transmits light emitted by the light source and directly contacts the human skin, while the cooling mechanism cools the light-transmitting crystal 400 to prevent burns. The cooling mechanism is located on the air inlet side of the fan blade 120, and the heat sink 110 is located on the air outlet side of the fan blade 120, ensuring airflow through both the cooling mechanism and the heat sink 110, allowing the airflow driven by the fan blade 120 to remove heat from both components. This application achieves heat dissipation for both the cooling mechanism and the heat sink 110 using a single cooling drive unit 100, where the cooling mechanism reduces the temperature of the light-transmitting crystal 400, and the heat sink 110 reduces the temperature of the light-emitting mechanism. The structure adopted in this embodiment is compact, and the layout of each part is well designed and makes full use of the internal space of the hair removal device's outer shell, so that the hair removal device can be made smaller while having a good heat dissipation effect.

[0052] In one embodiment, see Figures 5 to 9 The cooling mechanism includes a cooling element 510 and a heat-conducting component 520. The cooling element 510 is connected to the heat-conducting component 520 and is in contact with the light-transmitting crystal 400. The heat-conducting component 520 is disposed on the air inlet side of the cooling drive unit 100. The cooling element 510 absorbs heat from the light-transmitting crystal 400 and conducts the heat to the heat-conducting component 520. The heat on the heat-conducting component 520 is carried into the air by the airflow driven by the cooling drive unit 100.

[0053] The heat-conducting component 520 includes a heat sink 521, a heat pipe 522, and a second heat dissipation fin 523. One side of the heat sink 521 is in contact with the cooling chip 510, and the other side is connected to the heat pipe 522. The end of the heat pipe 522 away from the heat sink 521 is connected to the second heat dissipation fin 523, which is located on the air inlet side of the cooling drive 100. Specifically, the cooling chip 510 has a cold end and a hot end. The cold end of the cooling chip 510 is in contact with the light-transmitting crystal to cool it, while the hot end of the cooling chip 510 is in contact with the heat sink 521. The heat from the hot end of the cooling chip 510 is conducted to the second heat dissipation fin 523 via the heat sink 521 and the heat pipe 522. Driven by the fan blades 120 of the cooling drive 100, the airflow enters the hair removal device from the air inlet 201 and flows through the second heat dissipation fin 523, thereby carrying away the heat from the second heat dissipation fin 523. Multiple second heat dissipation fins 523 are provided to increase the contact area between the second heat dissipation fins 523 and the airflow, thereby improving heat dissipation efficiency.

[0054] In this embodiment, the hair removal device also includes an inner support 600, which is assembled inside the outer casing of the device. The inner support 600 is installed on the air inlet side of the cooling drive component 100, and the heat conduction component 520 is installed on the inner support 600. The inner support 600 is used to fix the position of the heat conduction component 520, making the internal structure of the hair removal device more compact.

[0055] In this embodiment, the light-emitting mechanism further includes a light source support 330 and a filter 340. The filter 340 and the reflector 320 enclose a cavity for the light source. The light source support 330 is connected to the light source to fix the light source within the cavity. Specifically, part of the light emitted by the light source passes directly through the filter 340 and the light-transmitting crystal 400 in sequence before being emitted outward, while another part is reflected by the reflector 320 and then passes through the filter 340 and the light-transmitting crystal 400 in sequence before being emitted outward.

[0056] In this embodiment, the hair removal device also includes a circuit board 700, a capacitor 800 and a charging head 900 connected to the circuit board 700. The circuit board 700 and the capacitor 800 are both assembled inside the main housing, the charging head 900 is installed at the bottom of the main housing, and the circuit board 700 is electrically connected to the light source and the fan blade 120.

[0057] In this embodiment, the light source is a lamp tube or other light-emitting device that can emit discontinuous strong pulse light.

[0058] In summary, the cooling drive component provided in this application has its top surface attached to the light-emitting mechanism. The heat sink, as part of the housing, also functions to dissipate heat emitted by the light-emitting mechanism. Heat is directly conducted through the heat sink, and when the fan blades drive the airflow, the airflow can pass over the surface of the heat sink to remove heat. A graphene heat-dissipating layer is coated on the heat sink to improve its heat dissipation efficiency. The heat sink is filled with a thermally conductive material, giving it high thermal conductivity and accelerating the transfer of heat from the light-emitting mechanism to the heat sink. Based on the aforementioned cooling drive component, this application also provides a hair removal device incorporating this cooling drive component. The cooling drive component can dissipate heat from the light-emitting mechanism while simultaneously cooling the cooling mechanism to accelerate the temperature drop of the light-transmitting crystal. The fan-driven airflow enters the hair removal device through the air inlet, passes through the heat-conducting component to remove heat, then enters the cooling drive component through the ventilation opening to remove heat from the cooling drive component, and finally exits from the bottom of the hair removal device. The heat sink is positioned in the direction of airflow to change the airflow direction, allowing the airflow to enter from the side of the cooling drive and exit from the bottom of the cooling drive. After the airflow is blocked by the heat sink, it flows along the heat sink. The fan blades are located on one side of the flat plate between the mating part and the first heat sink fin, ensuring that the airflow makes full contact with the heat sink as it flows along the flat plate, increasing heat dissipation. Simultaneously, the internal structure of the hair removal device is more compact, allowing for a thinner and lighter design, meeting the demand for smaller hair removal devices.
