The beauty instrument 100 according to the embodiment of the present invention will be described with reference to the drawings.

As shown in fig. 1, the beauty instrument 100 according to the embodiment of the present invention includes: a housing 1, a hair removal assembly 5, a cooling member 3 and a heat dissipation assembly 2.

An epilation assembly 5 is arranged in the housing 1, the epilation assembly 5 having a light-emitting channel extending in a first direction. That is, the hair removal assembly 5 has a light source (i.e., the light emitting member 51), and the hair removal assembly 5 emits light of a specific wavelength and acts on the skin to inhibit hair growth. The light-emitting channel here refers to an output channel of light emitted by the epilation assembly 5, the light-emitting channel extending in a first direction, i.e. the light emitted by the epilation assembly 5 is output in the first direction.

The light source of the epilation assembly 5 may here be located inside the housing 1, the housing 1 comprising a light exit area, the light striking channel extending from the light source towards the light exit area. In some embodiments, the light source of the hair removal assembly 5 is located on the housing 1 or extends outside the housing 1, and the light emitting channel is outside the housing 1 and is the space through which the light is emitted. When the refrigerating component 3, the depilating component 5 and the heat radiating component 2 are all arranged in the shell 1, on one hand, the components do not occupy the space outside the shell 1, so that the beauty instrument 100 is ensured to form an integral structure and is convenient to store and carry; on the other hand, the case 1 can protect the above components, and when the cosmetic apparatus 100 is used, the components are not damaged by external hard objects, so that the service life of the components is prolonged, the use cost of the cosmetic apparatus 100 is reduced, and the user experience is improved.

The cooling member 3 has a cold end and a hot end, the cold end being in contact with the epilating assembly 5. The refrigerating element 3 is a cooling element, and the refrigerating element 3 transfers heat from the cold end to the hot end during operation, so that the cold end can convey cold outwards, and the hot end can convey heat outwards. In some schemes, the refrigerating part 3 is a semiconductor refrigerating part, the semiconductor refrigerating part absorbs heat from the cold end after being electrified and releases heat from the hot end, for example, the semiconductor refrigerating part is a thermocouple structure formed by connecting an N-type semiconductor material and a P-type semiconductor material. The principle of the semiconductor refrigerating element is the prior art and is not described in detail herein. The shape of the refrigeration element 3 is not restricted in particular here. In another scheme, the refrigerating element is a liquid cooling radiator, and heat is transferred by liquid in circulation.

The heat radiation module 2 includes a heat sink 21 and a heat radiation fan 22. The heat sink 21 is located on a side of the hair removal element 5 facing away from the light exit direction, i.e. the heat sink 21 is located on a side of the hair removal element 5 opposite to the light exit direction. Radiator 21 is the device that in order to avoid influencing the normal work of part with the heat in time transfer that the part produced in the course of the work, and what radiator 21 adopted in this application scheme is air-cooled radiator. The heat sink 21 absorbs heat by its high thermal conductivity and dissipates heat to the air by its contact with the air.

The heat sink 21 includes: a first heat dissipation element 211, a second heat dissipation element 212 and a heat transfer connector 213, the first and second

heat dissipation elements

211 and 212 being arranged in a first direction, the first heat dissipation element 211 being in contact with the hot end of the refrigeration element 3, the heat transfer connector 213 being adapted to connect the first heat dissipation element 211 with the second heat dissipation element 212 for heat transfer.

The cooling element 3 thus releases cooling energy to the epilating assembly 5, which heat is transferred to the first heat dissipation element 211 and is dissipated by the first heat dissipation element 211. The first heat dissipation element 211 also transfers heat to the second heat dissipation element 212 through the heat transfer connector 213 and radiates the heat outward by the second heat dissipation element 212 and the heat transfer connector 213.

The heat dissipation fan 22 is used for driving an airflow to flow, and the airflow driven by the heat dissipation fan 22 flows through at least one of the first heat dissipation member 211 and the second heat dissipation member 212. Here, between the two heat dissipation members, the airflow driven by the heat dissipation fan 22 may flow through only the first heat dissipation member 211, the airflow driven by the heat dissipation fan 22 may flow through only the second heat dissipation member 212, and the airflow driven by the heat dissipation fan 22 may flow through the first and second

heat dissipation members

211 and 212. Whether flowing through the first heat dissipation member 211 or the second heat dissipation member 212, it is possible to enhance the air absorption of heat from the heat sink 21, improving the heat dissipation efficiency of the heat sink 21. It should be noted that the air flow driven by the heat dissipation fan 22 may be communicated with the air flow outside the casing 1, or the air flow driven by the heat dissipation fan 22 may flow only inside the casing 1, and the heat may be slowly dissipated to the outside in the internal circulation.

The area of the projection overlapping area of the first heat dissipation element 211 and the second heat dissipation element 212 along the first direction is S1, the area of the maximum side surface of the first heat dissipation element 211 is S2, the area of the maximum side surface of the second heat dissipation element 212 is S3, and S1 occupies more than half of at least one of S2 and S3. The projection in the first direction herein refers to a projection of the object on a perpendicular plane to the first direction. Taking a cartesian coordinate system as an example, assuming that the first direction is the X direction, the projection of the object along the first direction refers to the projection of the object on the YOZ plane. That is, the area of the projection overlapping area of the first heat dissipation element 211 and the second heat dissipation element 212 on the YOZ plane is S1, S1 may occupy more than half of S2, or S1 may occupy more than half of S3, or S1 is more than half of S2 and more than half of S3. Therefore, at least one of the first heat dissipation member 211 and the second heat dissipation member 212 has a larger area facing the hair removal assembly 5 and the cooling member 3, and can absorb more heat no matter heat conduction or convection, thereby improving the heat dissipation effect of the hair removal assembly 5 and the cooling member 3.

According to the beauty instrument 100 of the embodiment of the invention, a large amount of heat is generated during the working process of the depilating assembly 5, and through the arrangement of the refrigerating member 3 and the heat radiating assembly 2, the cold end of the refrigerating member 3 transmits cold energy to the depilating assembly 5 so as to reduce the temperature of the depilating assembly 5 during the working process, thereby prolonging the service life of the depilating assembly 5 on one hand, and preventing the depilating assembly 5 from transmitting heat to other parts to cause burning pain when a user uses the beauty instrument 100 on the other hand. By arranging the heat sink 2 and the hair removal assembly 1 along the first direction, the main functional components inside the beauty instrument 100 are arranged along the first direction in a concentrated manner, so that the structure is compact, and the overall size is reduced.

Alternatively, the cosmetic device 100 of the present application may be a depilating device, or other device that uses the depilating assembly 5 during a cosmetic procedure.

In some embodiments, as shown in fig. 2, the housing 1 includes a housing seat 11 and a housing cover 12, one side of the housing seat 11 is open, and the housing cover 12 is fitted over the open opening of the housing seat 11. The case base 11 and the case cover 12 are two independent parts, and in the process of assembling the beauty instrument 100, the refrigerating element 3, the depilating assembly 5, the heat radiating assembly 2 and other assemblies can be assembled in the case base 11, and then the case cover 12 is connected to the case base 11, so that the difficulty of assembling the beauty instrument 100 is reduced.

In some embodiments, the housing 1 is assembled and then the housing base 11 and the housing cover 12 are fixed and then not opened during the service life, for example by welding or riveting. In some embodiments, the housing cover 12 is detachably connected to the housing base 11, so as to facilitate the detachment when the cooling member 3, the hair removal assembly 5, the heat dissipation assembly 2, etc. in the housing 1 are damaged or need maintenance. The detachable connection can adopt a bolt connection or a clamping connection and other connection modes.

In the solution of the present application, the shape of the casing 1 is not limited in particular, and may be, for example, a rectangular parallelepiped shape, a cylindrical shape, etc., and for example, the casing 1 may include a plurality of sections, and different section shapes or thicknesses are different.

In other embodiments, the housing 1 may also be formed by splicing a left half shell and a right half shell, wherein the two half shells are open at the sides facing each other, and the two half shells are fastened to form one housing 1.

In some embodiments, as shown in fig. 1, the housing 1 includes a nose portion 171 and a handle portion 172, the handle portion 172 connecting the nose portion 171. The handle 172 is provided to facilitate the user's grip and to apply force to align the head 171 with the desired position for beauty treatment. The handle portion 172 is shaped to facilitate handling, and is not limited to a particular shape.

For example, in fig. 2, the nose portion 171 has an irregular rectangular parallelepiped shape, and the handle portion 172 has a rod shape.

Specifically, the hair removal assembly 5, the cooling member 3 and the heat dissipation assembly 2 are disposed in the head portion 171, so that the functional components can be concentrated in the head portion 171, and the handle portion 172 is not limited in size, which is beneficial to reducing the overall size of the hair removal assembly on the premise of compact internal components.

Specifically, as shown in FIG. 1, the heat transfer connector 213 has a bent segment 2133, the bent segment 2133 being disposed adjacent the handle portion 172, or the bent segment 2133 being at least partially disposed within the handle portion 172. The position of the bending section 2133 illustrates that the heat transfer connector 213 is bent at the side where the handle portion 172 is located, so that two ends of the heat transfer connector 213 can be connected to the first heat dissipation element 211 and the second heat dissipation element 212, and the first heat dissipation element 211 and the second heat dissipation element 212 are not hindered from being arranged along the first direction. Moreover, the bent segment 2133 utilizes the space of the handle portion 172 or utilizes the space adjacent to the handle portion 172, which makes the interior of the head unit 171 compact.

Optionally, a wind-blocking plate 173 for blocking air flow is disposed between the handle portion 172 and the nose portion 171, so that heat transfer to the handle portion 172 can be effectively prevented or reduced, and scalding of the handle portion 172 can be effectively alleviated or avoided.

In other embodiments, the heat transfer connector 213 does not have the bent portion 2133, and the heat transfer connector 213 may have a straight rod shape, a layered shape, or the like, for example, the heat transfer connector 213 is a heat conduction layer between the first heat dissipation member 211 and the second heat dissipation member 212.

In some embodiments, the housing 1 is assembled by two parts, a housing base 11 and a housing cover 12, wherein one side of the housing base 11 is open and the housing cover 12 covers the housing. On the other side of the housing base 11, a partial section projects in the first direction, so that the projecting section forms a deep cavity inside it for mounting the cooling member 3, the epilating assembly 5, the heat dissipating assembly 2, etc. The protruding portion corresponds to the nose portion 171 of the housing 1, and the non-protruding portion constitutes the handle section 172 of the housing 1. A wind deflector 173 is integrally formed in the housing base 11, and the wind deflector 173 is located in the handle section 172 such that the wind deflector 173 is free from the heat transfer connection 213.

Specifically, the air barrier 173 is at least one layer, which serves to block air circulation.

In some embodiments, as shown in fig. 2, the housing 1 includes: the head unit 171 and the handle unit 172, the hair removing assembly 5, the cooling member 3 and the heat dissipating assembly 2 are provided in the head unit 171. The light exit region of the housing 1 is provided in the head 171. The handle portion 172 is formed by extending a portion of the head portion 171 away from the light exit area in a direction perpendicular to the first direction, so that the beauty instrument 100 is shaped like a "7". Accordingly, the heavy components of the beauty instrument 100 are mainly concentrated in the head portion 171, and the handle portion 172 is relatively light and easy to hold, and is comfortable in holding posture when performing beauty treatment on different parts of the body.

Furthermore, the weight of the head unit 171 is heavy, and the weight of the head unit 171 can make the head unit 171 more easily press the skin after the user holds the handle unit 172 and brings the light-emitting area close to the skin or close to the skin. Thereby, the possibility of damaging the surrounding skin by the light emitted from the epilation assembly 5 is effectively reduced. When the beauty instrument 100 is used normally, light leakage is not easy, the probability of light emitting to a user or eyes of surrounding people can be reduced, and the safety is higher.

Specifically, the controller of the cosmetic instrument 100 may be disposed within the handle portion 172, or at least a portion of the circuitry of the cosmetic instrument 100 may be located within the handle portion 172. This allows the space within the handle portion 172 to be fully utilized without adding excessive weight to the handle portion 172. The controller or circuitry disposed on the handle portion 172 allows the head portion 171 to be in space, which advantageously reduces the overall size of the head portion 171, resulting in a smaller head portion 171.

Alternatively, the controller may be a circuit board or an electronic control box, etc.

In some embodiments, the cross-sectional area of the nose portion 171 gradually decreases in a direction toward the light exit area, and the cross-sectional area refers to an area of the nose portion 171 on a plane perpendicular to the first direction. For example, the light exit region is located at the lower end of the nose part 171, the cross-sectional area of the nose part 171 gradually decreases in the downward direction. Thus, the upper end of the nose portion 171 is large to provide a sufficient accommodation space, while the lower end of the nose portion 171 is small to reduce the contact area of the nose portion 171 with the skin, which is advantageous for increasing the pressure so that the nose portion 171 is pressed more tightly against the skin.

Also in other embodiments, the width of the nose portion 171 gradually decreases in a direction toward the light exit area, and the width refers to a dimension of the nose portion 171 in a direction perpendicular to the first direction and perpendicular to the handle portion 172. For example, if the light emitting area is located at the lower end of the head unit 171, the head unit 171 becomes narrower downward. This also allows the nose portion 171 to have a smaller contact area with the skin, which is beneficial to increase the pressure and make the nose portion 171 press more tightly against the skin.

In some embodiments of the present invention, as shown in fig. 4, the housing 1 has a heat dissipation air duct 151 therein, and the heat dissipation fan 22 circulates the heat dissipation air duct 151 with air flow. The heat dissipation duct 151 may guide the incoming airflow to flow in a predetermined flow direction and flow out of the beauty instrument 100, thereby improving heat dissipation efficiency.

Specifically, the housing 1 is formed with an air outlet 1121 and an air inlet 1211 that are communicated with the heat dissipation duct 151. During the operation of the heat dissipation fan 22, ambient air at normal temperature enters the heat dissipation air duct 151 in the housing 1 through the air inlet 1211, and then flows along the extending direction of the heat dissipation air duct 151 to take away heat, so that the heat is discharged from the air outlet 1121, thereby ensuring smooth and stable discharge of the heat and improving the heat dissipation efficiency.

Optionally, as shown in fig. 1 and fig. 4, the hot end surface 311 of the refrigeration element 3 is disposed in the heat dissipation air duct 151, and when the cooling fan 22 operates, the air flow entering through the air inlet 1211 blows to the hot end surface 311 of the refrigeration element 3 through the heat dissipation air duct 151, so as to take away heat on the hot end surface 311, and then the heat is discharged from the air outlet 1121, so as to achieve the purpose of heat dissipation.

In some embodiments, the heat dissipation fan 22 drives the airflow to be sucked from the air inlet 1211, and exhausted from the air outlet 1121 after flowing through the heat dissipation device 21. Wherein the first heat dissipation element 211 is located upstream or downstream of the second heat dissipation element 212 in the flow direction of the airflow. That is, the airflow driven by the heat dissipation fan 22 may flow through the first heat dissipation element 211 and then flow through the second heat dissipation element 212, or may flow through the second heat dissipation element 212 and then flow through the first heat dissipation element 211. Although the heat dissipation sequence is different, the heat dissipation purpose can be achieved.

Specifically, the air intake 1211 is positioned at a side of the second heat dissipation member 212 remote from the first heat dissipation member 211 such that the air intake 1211 faces the second heat dissipation member 212. It is understood that the probability of contact with the outside air is maximized at the air inlet 1211 and the distance from the outside is short, so that the air over-flow rate of the second heat dissipation member 212 can be made large.

Further, at least a portion of the air outlet 1121 is located on a side of the first heat dissipation member 211 away from the second heat dissipation member 212. Thus, the air flow has a far blowing path in the shell 1, and the air flow has a larger heat absorption range.

In some embodiments, as shown in fig. 1 and 2, the air inlet 1211 is disposed on the housing cover 12, and the air inlet 1211 is disposed opposite to the heat dissipation assembly 2, so that the air is blown through the heat dissipation assembly 2 at the lowest temperature, and the heat exchange efficiency is high.

Specifically, air outlet 1121 is provided in housing 11 such that air outlet 1121 is adjacent to a member in the vicinity of depilating assembly 5.

Of course, the positions of the air inlet 1211 and the air outlet 1121 in the present embodiment may be adjusted according to the requirement, for example, the positions of the air inlet 1211 and the air outlet 1121 in fig. 2 may be interchanged, such that the air flow enters and then flows through the first heat dissipation member 211, and finally flows through the second heat dissipation member 212 and then is discharged.

In some embodiments, the first heat dissipation element 211 is spaced apart from the second heat dissipation element 212 to form an intermediate cavity therebetween, which allows the two heat dissipation elements to be spread out and spread out, allowing heat to be spread out to a larger space. In the description of the present invention, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features for distinguishing between the described features, whether they are sequential or not.

In some embodiments, first heat dissipation element 211, second heat dissipation element 212 are spaced apart in a first direction with an intermediate cavity therebetween. Here, the projection of the first heat dissipation element 211 and the projection of the second heat dissipation element 212 in the first direction overlap each other, and the projection of the intermediate cavity in the first direction is the same. That is, the space partitioned between the first and second

heat dissipation members

211 and 212 is an intermediate cavity, which may be empty, allowing heat to be diffused into the intermediate cavity. The intermediate chamber may also house components.

Here, a middle cavity is formed, on both sides of which are the first and second

heat dissipation elements

211, 212, where sufficient heat can be absorbed to cool the first and second

heat dissipation elements

211, 212, such that the first and second

heat dissipation elements

211, 212 can absorb more heat from the epilation assembly 5.

In the present application, the first heat dissipation member 211 and the second heat dissipation member 212 are spaced apart in the first direction, and the first heat dissipation member 211 and the second heat dissipation member 212 are disposed to face each other, so that an intermediate cavity formed therebetween has a large area and a large heat receiving capacity. In the solution of the present application, when the heat dissipation fan 22 is disposed in the housing 1, the heat dissipation air duct 151 is formed in the housing 1. The airflow driven by the heat dissipation fan 22 flows along the heat dissipation air duct 151, and the heat dissipation air duct 151 may guide the airflow so that the airflow flows in a predetermined flow direction. Therefore, the airflow flowing direction is orderly, so that the wind resistance energy consumption can be reduced, the airflow can flow through the radiator 21 and even through the refrigerating part 3, and the heat exchange capacity between the parts and the air is improved.

In some embodiments, the airflow driven by the heat dissipation fan 22 flows through the middle chamber, that is, the middle chamber is a middle ring of the heat dissipation air duct 151. Because the two sides of the middle cavity are heated, the middle cavity becomes a heat accumulation area, so that the air flow driven by the cooling fan 22 flows through the middle cavity, the concentrated heat is intensively blown away by the air flow, and the heat exchange efficiency is high.

The temperature of the radiating piece is reduced, the heat concentrated in the middle cavity and the radiating piece with higher temperature can be rapidly transmitted to the radiating piece with lower temperature, so that the cooling is rapid, and the cooling rate is improved.

In some embodiments, the heat dissipation fan 22 is an axial fan, and the rotation axis of the heat dissipation fan 22 is arranged along a first direction. An extension line of the rotation shaft of the heat radiating fan 22 is disposed through the refrigerating member 3. This allows the airflow passing through the first heat dissipation member 211 and the second heat dissipation member 212 to have a larger airflow, the strongest airflow, and a higher heat dissipation performance.

In some specific embodiments, the first heat dissipation member 211 and the second heat dissipation member 212 are arranged at an interval, and the heat dissipation fan 22 is arranged between the first heat dissipation member 211 and the second heat dissipation member 212, so that on one hand, the heat dissipation fan 22 does not occupy a space outside the heat sink 21, and the structure of the heat dissipation assembly 2 is more compact, thereby ensuring that the whole volume of the beauty instrument 100 is smaller, facilitating use, storage and carrying, and improving user experience; on the other hand, the relative positions of the first heat dissipation element 211, the second heat dissipation element 212 and the heat dissipation fan 22 in the heat dissipation assembly 2 and the matching heat dissipation relationship therebetween can improve the heat dissipation efficiency.

Of course, in other examples, the radiator fan 22 is not limited to be disposed between the first radiator member 211 and the second radiator member 212, and the radiator fan 22 may be disposed at other positions, for example: the radiator fan 22 is disposed on a side of the second radiator member 212 remote from the first radiator member 211, or the radiator fan 22 is disposed on a side surface of the second radiator member 212, or the like. The specific location of the heat dissipation fan 22 is not limited, as long as the heat dissipation fan 22 can ensure that air flows in the heat dissipation air duct 151 during operation.

Alternatively, the radiator fan 22 is disposed between the first and

second radiator members

211 and 212 and adjacent to the second radiator member 212. That is to say, the heat dissipation fan 22 is disposed far away from the first heat dissipation element 211 relative to the second heat dissipation element 212, and the first heat dissipation element 211 is disposed near the hot end surface 311 of the refrigeration element 3, so that the temperature of the first heat dissipation element 211 is relatively high, and the heat dissipation fan 22 is disposed far away from the first heat dissipation element 211, so that the heat of the first heat dissipation element 211 can be prevented from being transferred to the heat dissipation fan 22, and the service life of the heat dissipation fan 22 is prolonged.

In some embodiments, both ends of the heat transfer connector 213 are connected to the first heat dissipation member 211 and the second heat dissipation member 212, respectively, and the heat transfer connector 213 is disposed to avoid the middle chamber. Specifically, the portion of the heat transfer connector 213 between the first heat dissipation element 211 and the second heat dissipation element 212, which is not inside the intermediate cavity, may be provided from the side of the intermediate cavity. Thus, the heat transfer connector 213 can reduce flow obstruction to the air flow, and interference with the heat transfer connector 213 is small when the component is mounted in the middle chamber.

In some embodiments, the heat transfer connector 213 is in contact with the hot end of the refrigeration member 3. It will be appreciated that the heat transfer connector 213, which has a high thermal conductivity, is in contact with the hot end of the cooling element 3 to quickly conduct heat from the heating element 3 and then quickly dissipate the heat to the first and second

heat dissipation elements

211, 212.

In some embodiments, heat transfer connector 213 is an elbow, such that the position of heat transfer connector 213 is flexibly arranged when connecting first heat dissipation element 211 with second heat dissipation element 212.

A heat conducting medium is arranged in the heat transfer connecting piece 213, the heat conducting medium is fluid, and the conductivity of the heat conducting medium is larger than that of air. Alternatively, the heat transfer connector 213 is formed in a hollow structure, for example, the heat transfer connector 213 is formed as a heat transfer pipe, and the inside of the heat transfer pipe is provided with a cooling medium for transferring heat in the first heat dissipation member 211 to the second heat dissipation member 212 for the purpose of dissipating heat from the hot end surface 311. The cooling medium may be one of cooling water, cooling liquid, or cooling gas.

Specifically, as shown in fig. 6 and 7, both ends of the heat transfer connector 213 are inserted into the first and second

heat dissipation members

211 and 212, respectively. Therefore, on one hand, the processes of screwing and welding can be omitted by utilizing the insertion fit and the installation and fixation of the heat transfer connecting piece 213, and on the other hand, the contact area of the heat transfer connecting piece 213 with the first radiating piece 211 and the second radiating piece 212 can be increased, and the heat transfer capacity of the joint can be improved.

In some embodiments, heat transfer coupling 213 comprises: the heat radiator comprises a first straight pipe section 2131, a second straight pipe section 2132 and a bent section 2133, wherein the first straight pipe section 2131 is inserted into the first heat radiator element 211, the second straight pipe section 2132 is inserted into the second heat radiator element 212, and the bent section 2133 is connected with the first straight pipe section 2131 and the second straight pipe section 2132. The straight pipe section is designed, so that the insertion is labor-saving and quick.

Specifically, the bent section 2133 is connected to the same end of the first straight section 2131 and the second straight section 2132, and the heat transfer connector 213 is U-shaped. The processing equipment of the U-shaped pipe is mature and has high qualification rate. Optionally, the end of the second straight tube section 2132 remote from the bent section 2133 is pointed, so that the second straight tube section 2132 can be inserted into the second heat sink 212 with a pointed end, with reduced insertion resistance.

Further, the number of the heat transfer connectors 213 is two, the first straight tube sections 2131 of the two heat transfer connectors 213 are parallel, the second straight tube sections 2132 of the two heat transfer connectors 213 are parallel, and the bent sections 2133 of the two heat transfer connectors 213 form an included angle. The included angle is set so that the relative angle and distance between the first heat dissipation member 211 and the second heat dissipation member 212 are stabilized by the heat transfer connector 213.

In some embodiments, the second heat dissipation element 212 includes a plurality of spaced fins 2121, and the fins 2121 extend along the first direction. The fins 2121 are designed to reduce airflow resistance and increase airflow, and the air channel formed between the two fins 2121 can guide airflow to flow in the first direction. The flowing direction of the airflow is opposite to the heat transmission direction, and the heat exchange efficiency can be further improved through convection.

Specifically, the dimensions of the first heat dissipation element 211 and the second heat dissipation element 212 in the first direction are thicknesses, and the thickness of the first heat dissipation element 211 is smaller than the thickness of the second heat dissipation element 212. That is, the first heat dissipation member 211 is relatively thin. Since the first heat dissipation member 211 is in contact with the hot end of the cooling member 3, the temperature of the first heat dissipation member 211 is relatively higher, and the first heat dissipation member 211 is made thinner, so that the transfer path of the heat absorbed by the first heat dissipation member 211 from the hot end in the first direction is shorter, and when air blows from the side of the first heat dissipation member 211 adjacent to the second heat dissipation member 212, the heat can be taken away by the air as early as possible. If the first heat dissipation member 211 dissipates heat by the second heat dissipation member 212, the heat of the first heat dissipation member 211 can be transferred to the second heat dissipation member 212 as early as possible. Since the second heat dissipation member 212 includes the fins 2121, the air flow flux is large, and thus heat can be dissipated as quickly as possible by the second heat dissipation member 212.

Further, a projected area of the first heat dissipation element 211 in the first direction is smaller than a projected area of the second heat dissipation element 212, that is, the projected area of the first heat dissipation element 211 is relatively small, and the projected area of the second heat dissipation element 212 is relatively large. With such an arrangement, the heat dissipation modes of the first heat dissipation member 211 and the second heat dissipation member 212 can be matched, and meanwhile, the area of the first heat dissipation member 211 is relatively small, so that more air can circulate around the first heat dissipation member 211 in the housing 1, and even the size of the housing 1 at the first heat dissipation member 211 is reduced.

It will be appreciated that the first heat dissipation element 211 has a high heat transfer coefficient, and that the first heat dissipation element 211 is arranged to dissipate heat from the epilation assembly 5 in a manner that takes advantage of the high thermal conductivity. Therefore, even if the projection area of the first heat dissipation member 211 in the first direction is small, the energy conduction capability of the first heat dissipation member 211 is still strong, and heat can be quickly guided to the second heat dissipation member 212. The second heat dissipation member 212 includes a plurality of fins 2121, and the heat dissipation manner is to allow the flowing air to take away heat by using the contact area between the fins 2121 and the air. It is required that the projected area of the second heat dissipation member 212 is larger so that more air can flow through the second heat dissipation member 212.

Alternatively, the first heat dissipation element 211 may be an aluminum element, a copper element, or another material with high heat transfer efficiency.

Alternatively, the first heat dissipation member 211 is a block body, so that the heat transfer amount can be maintained large when the first heat dissipation member 211 has a small volume.

Optionally, the second heat dissipation element 212 is an aluminum body or a copper element, or other material with high heat transfer efficiency. In other embodiments of the present application, the second heat dissipation element 212 may have other shapes, for example, the second heat dissipation element 212 may include a plurality of fins or spiral fins, or the like, or the second heat dissipation element 212 may include a plurality of tubes, or the like.

Specifically, as shown in fig. 4 and fig. 1, a first insertion hole 2115 is formed in the first heat dissipation member 211, a second insertion hole 2125 is formed in the second heat dissipation member 212, a first straight tube section 2131 of the bent section 2133 is inserted into the first insertion hole 2115 of the first heat dissipation member 211, and a second straight tube section 2132 of the bent section 2133 is inserted into the second insertion hole 2125 of the second heat dissipation member 212.

Optionally, the first receptacle 2115 is a cylindrical bore perpendicular to the first direction. Alternatively, the second insert hole 2125 is a semi-cylindrical hole perpendicular to the first direction, the second insert hole 2125 being open on the side facing the refrigerant element 3 so that the second straight tube section 2132 of the heat transfer connector 213 is in contact with the hot end of the refrigerant element 3.

Alternatively, the tube body of the heat transfer connector 213 is made of a copper tube, and the heat conductivity coefficient of the copper tube is higher than that of a common material and higher than that of aluminum. By means of its contact with the hot end of the refrigerating element 3, heat can be conducted away more efficiently.

In some embodiments, the thickness of the refrigeration element 3 is flanked by a cold end surface 321 and a hot end surface 311. Here, the cooling member 3 includes a cold end surface 321 and a hot end surface 311, and the cold end surface 321 and the hot end surface 311 are oppositely disposed in a thickness direction of the cooling member 3, that is, in the thickness direction of the cooling member 3, one side of the cooling member 3 has the cold end surface 321, and the other side of the cooling member 3 has the hot end surface 311. The cold side surface 321 of the refrigerant element 3 is arranged to absorb heat and the hot side surface 311 of the refrigerant element 3 is arranged to dissipate heat. The cold end surface 321 of the cooling member 3 is in contact with the epilating assembly 5 and the hot end surface 311 of the cooling member 3 is in contact with the heat dissipating assembly 2. Specifically, the thickness direction of the refrigeration element 3 is parallel to the first direction, and the thickness direction of the refrigeration element 3 may be the up-down direction shown in fig. 1.

As shown in fig. 1, the hair removal assembly 5 comprises a light emitting member 51, the light emitting member 51 emitting light along a lighting channel. The light emitting member 51 of the hair removal assembly 5 is adapted to emit light of a specific wavelength, and the light emitted from the light emitting member 51 is emitted through the light-emitting region and acts on the skin of the user for cosmetic purposes. In some examples, the light emitting element 51 may be a light tube, or other light emitting elements 51 capable of emitting light with a specific wavelength may be used, and the specific type is not limited in this application.

In some embodiments, as shown in fig. 4, the cosmetic apparatus 100 further comprises: the inside of casing 1 is located to separator 4, and the inner chamber of casing 1 is equipped with separator 4 including wind chamber 15 and no wind chamber 16 between wind chamber 15 and the no wind chamber 16, and heat-radiating component 2 is located there is wind chamber 15, and the subassembly 5 that moults is located no wind chamber 16.

Specifically, the partition 4 participates in the divided windy cavity 15 and windless cavity 16, and it should be noted that the meaning of "the partition 4 participates in the division" is that the partition is separated by the partition 4 alone, or the partition 4 cooperates with other components together.

The interior of the shell 1 is divided into a wind cavity 15 and a non-wind cavity 16 by the partition 4, and the heat dissipation assembly 2 can better exchange heat with air in the wind cavity 15. The absence of air flow through the hair removing member 5 in the air-free chamber 16 can reduce air flow, thereby improving the cleanliness of the hair removing member 5 and reducing wind resistance and noise. And no wind blows to the hair removal assembly 5, moisture in the air can not flow into the airless cavity 16 to influence circuits and devices, and the power utilization safety is improved. The chance of water and mist formation in the epilating assembly 5 is reduced and the lifetime of the epilating assembly 5 is extended.

It should be noted that, because there are two independent spaces (the wind chamber 15 and the no-wind chamber 16) in the housing 1 of the present application, the cooling member 3 may be disposed in the wind chamber 15 or the no-wind chamber 16. For example, in the example shown in fig. 4, the hot end surface 311 of the cooling member 3 is disposed in the air cavity 15, and the cold end surface 321 of the cooling member 3 is disposed in the air-free cavity 16, so as to ensure that the hot end surface 311 can be disposed toward the heat dissipation assembly 2, thereby improving the heat dissipation efficiency, the cold end surface 321 is disposed toward the hair removal assembly 5, thereby improving the cooling effect, and ensuring that the hot end surface 311 is disposed away from the air-free cavity 16, increasing the distance between the hot end surface 311 and the air-free cavity 16, and ensuring that the heat generated by the hot end surface 311 does not affect the temperature in the air-free cavity 16 as much as possible.

It can be understood that compared with the related art, the beauty instrument 100 of the present application has two independent spaces inside the housing 1, and the heat dissipation assembly 2 and the hair removal assembly 5 are respectively located in different spaces to ensure the independence of heat dissipation and cooling, so as to ensure that the heat of the heat dissipation assembly 2 is not transferred to the hair removal assembly 5 when the cooling member 3 dissipates heat, and prolong the service life of the hair removal assembly 5.

Specifically, the partition 4 includes a partition portion 41, the partition portion 41 being annular to be disposed around the cooling member 3, the cooling member 3 participating in the partition of the windy chamber 15 and the airless chamber 16. So set up, baffle portion 41 can not block the cold volume of refrigeration piece 3, thermal transfer, but also can help refrigeration piece 3 to separate the space of cold junction, hot junction, reduces the air around and conducts heat between cold junction, hot junction.

In some embodiments of the present invention, as shown in fig. 4 and 5, the cooling member 3 includes a circumferential side surface connected between the cold end surface 321 and the hot end surface 311, and the partition member 4 includes a partition portion 41, the partition portion 41 being annular to be disposed around the circumferential side surface of the cooling member 3, so that the partition portion 41 and the cooling member 3 together partition the inner cavity of the casing 1 into the air chamber 15 and the no-air chamber 16. The partition plate part 41 is matched with the refrigerating piece 3, on one hand, the partition plate part 41 can play a role in supporting, limiting and avoiding the cold end surface 321 of the refrigerating piece 3, so that the position stability of the refrigerating piece 3 is improved, and the refrigerating piece 3 can stably transmit cold energy to the unhairing assembly 5; on the other hand, refrigeration piece 3 plays the effect of filling baffle portion 41, sets up separator 4 in the inner chamber of casing 1, and refrigeration piece 3 and separator 4 cooperate in order to be divided the inner chamber of casing 1 for there being wind chamber 15 and no wind chamber 16, and guarantee that there are wind chamber 15 and no wind chamber 16 mutually independent, do not switch on each other.

Alternatively, as shown in fig. 4, the spacer 41 is disposed adjacent the cold end surface 321 relative to the hot end surface 311. The cold quantity of cold junction surface 321 of refrigeration piece 3 can be fully utilized, baffle portion 41 is cooled, the temperature of baffle portion 41 is reduced, avoid baffle portion 41 to transfer heat to no wind cavity 16, also can understand, separator 4 sets up apart from hot junction surface 311 of refrigeration piece 3, in order to increase the distance between separator 4 and hot junction surface 311, reduce separator 4 from the heat absorption capacity of hot junction surface 311, the purpose of heat transfer to moult subassembly 5 of separation hot junction surface 311 as far as possible, the life of subassembly 5 that further prolongs moults, and promote user experience.

Alternatively, the outer annular surface of the bulkhead portion 41 is in sealing engagement with the housing 1. The outer annular surface is a side surface of the partition plate portion 41 far away from the refrigerating element 3, and the outer annular surface is in sealing fit with the housing 1 to ensure that air in the air cavity 15 and the non-air cavity 16 cannot circulate through the joint of the partition plate portion 41 and the housing 1, that is, to ensure that the air cavity 15 and the non-air cavity 16 form two independent units, so that heat of the air cavity 15 cannot be transferred into the non-air cavity 16 to affect the depilating assembly 5, and heat dissipation and light irradiation are independent of each other.

Note that the outer annular surface of the partition plate portion 41 is in sealing engagement with the housing 1: either a direct sealing engagement, i.e., the outer annular surface of the partition portion 41 is in direct contact with the housing 1 to achieve a sealing engagement, or an indirect sealing engagement, i.e., the outer annular surface of the partition portion 41 is in contact with the housing 1 via an intermediate seal member to achieve a sealing engagement,

in some examples, when the outer annular surface of the barrier portion 41 is in direct contact with the housing 1 to achieve a sealing fit, for example, in some examples, the outer annular surface of the barrier portion 41 may be an interference fit with the housing 1. Alternatively, in another example, the outer annular surface of the partition plate portion 41 and the casing 1 may be connected by bonding, and the outer annular surface of the partition plate portion 41 is bonded to the inner wall surface of the casing 1. Alternatively, the shape of the outer annular surface of the partition plate portion 41 matches the shape of the inner wall surface of the casing 1, so that the wind chamber 15 and the no-wind chamber 16 which are independent of each other are formed in the inner cavity of the casing 1, the connection strength of the partition 4 and the casing 1 is increased, and the stable position of the partition 4 in the casing 1 is ensured.

Of course, in other examples, the spacer 4 is not limited to be connected to the housing 1 by the above-mentioned bonding method, but a detachable connection method such as bolt connection or clamping connection may be used to connect the spacer 4 to the housing 1, so as to reduce the difficulty of the mounting and dismounting of the spacer 4. In the present application, the specific connection manner of the partition portion 41 and the housing 1 is not limited as long as the outer annular surface of the partition portion 41 is ensured to be in sealing fit with the housing 1.

Alternatively, as shown in fig. 4, a flow guide surface 411 is formed on a surface of the partition plate portion 41 facing the air chamber 15. The flow guide surface 411 is used for improving the heat dissipation efficiency of the heat dissipation assembly 2, when the heat dissipation assembly 2 dissipates heat to the hot end surface 311, the flow guide surface 411 can guide the flow of air flow, the obstruction caused by the flow of the air flow is reduced, ventilation and heat dissipation are facilitated, and part of heat in the air cavity 15 can be quickly transmitted to the shell 1 through the flow guide surface 411 and then transmitted to the outside of the shell 1 through the shell 1, the heat dissipation purpose is achieved, and the heat dissipation efficiency is improved.

As shown in fig. 2 and 4, the casing 1 is formed with an air outlet 1121, and the diversion surface 411 extends smoothly toward an edge of the air outlet 1121 along a direction from the inner ring surface to the outer ring surface of the partition portion 41, so as to guide at least part of the air flow induced by the heat dissipation fan 22 to flow out of the air outlet 1121 through the diversion surface 411. The heat dissipation fan 22 is mainly used to accelerate the flow of the airflow in the air cavity 15, the flow guiding surface 411 with a smoothly extending edge is used to guide the airflow to the air outlet 1121, and the flow guiding surface 411 does not obstruct the flow of the airflow in the flow guiding process, so as to improve the airflow flow efficiency, and then the airflow is transmitted to the outside of the housing 1 through the air outlet 1121, so as to achieve the purpose of heat dissipation.

In some embodiments of the present invention, as shown in fig. 1 and 4, the hair removal assembly 5 further comprises a heat conductor 52, the heat conductor 52 is disposed in the airless chamber 16, a mounting chamber 521 is formed in the heat conductor 52, the luminous member 51 is disposed in the mounting chamber 521, and the cold end surface 321 of the cooling member 3 transmits cold to the heat conductor 52. The installation cavity 521 provides an avoiding space for the arrangement of the luminous element 51, and the luminous element 51 is arranged in the installation cavity 521, on one hand, the installation cavity 521 is used for limiting the propagation direction of light, so that the light emitted by the luminous element 51 can be emitted along a given direction and acts on the skin of a user, and the utilization rate of the light is improved; on the other hand, cold junction surface 321 of refrigeration piece 3 transmits cold volume to heat conduction piece 52, and heat conduction piece 52 transmits cold volume to installation cavity 521 in to the cooling of illuminating part 51, when the life of extension illuminating part 51 was used, still improved illuminating part 51 to the problem of other subassemblies heat transfer, for example, reduced illuminating part 51 and transmitted heat to the printing opacity cold compress 6 that follows below, guaranteed that the temperature of printing opacity cold compress 6 can not be too high, thereby reduce the pricking sense when cosmetic, promote user experience.

Alternatively, as shown in fig. 7, the light exit region is formed as the mounting opening 111, and the heat conductive member 52 is formed with a light exit 522 communicating with the mounting cavity 521. The light emitted from the light emitting member 51 by disposing the light emitting member 51 in the mounting cavity 521 can be guided out from the light outlet 522 and the mounting opening 111 in sequence to ensure that the light emitted from the light emitting member 51 can act on the skin of the user.

Optionally, the light outlet 522 and the cooling member 3 are located on opposite sides of the heat conductor 52. That is, the light outlet 522 is opened on the heat transfer member 52 and is disposed away from the cooling member 3 to guide the light emitted from the light emitting member 51 toward the light outlet area away from the cooling member 3. The refrigerating part 3 is located on one side of the heat conduction part 52 departing from the light outlet 522, and has a large installation space, so that the arrangement area of the refrigerating part 3 can be increased as much as possible, and the cooling effect of the refrigerating part 3 is improved.

Optionally, as shown in fig. 4 and 7, the beauty instrument 100 further includes a transparent cold compress 6, the transparent cold compress 6 is disposed at the light outlet 522 and exposed from the mounting opening 111, and the cold end surface 321 of the cooling member 3 transmits cooling energy to the transparent cold compress 6 through the heat conductive member 52. Printing opacity cold compress 6 is suitable for with user skin direct contact, and the cold junction surface 321 of refrigeration piece 3 avoids printing opacity cold compress 6 to scald the user through heat conduction piece 52 to printing opacity cold compress 6 feels with the pricking when user skin contact to slow down printing opacity cold compress 6, reaches the effect of cold compress.

It should be noted that the cold compress as used herein does not mean a temperature of up to 0 c, as long as it is ensured that the temperature of the light-transmissive cold compress 6 is less than or equal to the body temperature of the user, and the user does not feel that the light-transmissive cold compress 6 is hot during use.

Therefore, the heat conduction member 52 is arranged, so that the service life of the luminous member 51 can be prolonged, and the temperature of the light-transmitting cold compress member 6 can be reduced.
