Description

TECHNICAL AREA

[0001] The present disclosure relates to the field of hair removal and beauty care, and in particular to a portable hair removal device. BACKGROUND

[0002] Light-based hair removal technology is a non-invasive, modern hair removal method that safely, quickly, and efficiently removes unwanted hair from the body. Specifically, light-based hair removal is based on the theory of selective photothermolysis, where a specific wavelength of light can penetrate the epidermis without damaging the epidermal hair follicles. Melanin in the hair shaft selectively absorbs light energy, causing the hair follicles to coagulate and become necrotic during heating, effectively slowing hair growth and thus achieving hair removal.

[0003] However, it is known that any light generated during use produces a lot of heat, leading to a burning sensation on the skin, especially with a portable household hair removal device. To make them easier for users to hold and use, all portable hair removal devices are designed to be relatively small, which can make it easier for heat to build up. If heat dissipation and temperature reduction cannot occur in time, users will experience significant pain, redness, and swelling, and it can even pose a safety risk.

[0004] To reduce the heat generated during hair removal by the portable hair removal device, the prior art incorporates a sealing element within a heat dissipation structure. Furthermore, an opening is provided on the sealing element, which connects to the outer surface to align with a heat dissipation fin. This fin independently forms a channel for a heating element, which requires cooling to dissipate heat, thus effectively improving heat dissipation and temperature reduction. However, the portable hair removal device has more than one heat-generating element, and internal circuits and other components also generate heat. Consequently, current challenges include how all heat-generating elements can dissipate heat at the same power output, and how the cooling effect can be improved and efficiency maximized. SUMMARY

[0005] To solve a problem of incomplete temperature reduction of an existing portable hair removal device, the present disclosure provides a portable hair removal device.

[0006] To solve the aforementioned technical problem, the present disclosure provides a technical solution as follows: A portable hair removal device comprising a housing, a hair removal mechanism, and a heat dissipation mechanism within the housing, wherein the housing is provided with at least two outlets and an inlet; wherein the heat dissipation mechanism comprises a heat-conducting component; wherein the inlet is separately connected to different outlets to form at least two channels; wherein each of the channels is provided with a heat-generating element; and wherein, after being introduced from the inlet under the guidance of the heat-conducting component, an external cooling medium flows separately through different channels and is then expelled from a corresponding outlet, and in this process the external cooling medium dissipates heat from a separately flowed area out of the housing.

[0007] A portable hair removal device comprises a light-emitting body and the protruding portable hair removal device.

[0009] To clarify and make the tasks, technical solutions, and advantages of this disclosure more understandable, it is described in more detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein serve only to illustrate this disclosure and are not intended to limit it. Example 1:

[0010] In relation to Fig. Figure 1 of the present disclosure provides a portable hair removal device 100 configured to remove unwanted hair from a human body, comprising a housing 1 and a cold-compression section 221 with a translucent and cooling effect. A user can firmly attach the cold-compression section 221 to a human skin surface; the portable hair removal device 100 emits light, and the light penetrates the cold-compression section 221 and enters the skin surface to reach the root of a hair follicle, causing the hair follicle to coagulate and become necrotic, thus removing the hair.

[0011] The housing 1 mainly plays a role in protecting internal elements, and the overall shape of the housing 1 is not limited; it can be U-shaped, T-shaped, shuttle-shaped, or elongated-striped, or optionally elongated-striped cylindrical.

[0012] The housing 1 has a holding section 13 and a head section 12, with the head section 12 located at an end facing the human skin and the holding section 13 running parallel to the head section 12. Once the head section 12 is firmly connected to the holding section 13, a receiving chamber is formed inside, and the cold compression section 221 is exposed within this receiving chamber, free from the head section 12, to serve as a carrier for emitting light and making contact with the human skin. The holding section 13 is used to hold the portable hair removal device 100 to facilitate operation by the user.

[0013] In relation to Fig. 2 The housing 1 has an upper housing 101 and a lower housing 102, which can be formed by joining the upper housing 101 and the lower housing 102 by screw connection or clamp connection, or which can be formed by integral processing, or which can optionally be formed by joining in a clamping manner to facilitate disassembly and assembly.

[0014] A hair removal device 2, a circuit device 3, and a power supply device 4 are contained within the housing 1. The hair removal device 2, the circuit device 3, and the power supply device 4 are all sequentially electrically connected. The power supply device 4 can supply electrical energy to the hair removal device 2, allowing the hair removal device 2 to be used without connecting an external circuit or by directly using an external power source, such as a dry cell battery or a rechargeable battery. Therefore, the hair removal device 2 is convenient to store and transport and can be used outdoors.The circuit device 3 can be externally connected to an external circuit to charge the power supply device 4 and to turn the entire portable hair removal device 100 on / off, regulate the power and ensure temperature protection.

[0015] A person skilled in the art can understand that during operation all elements in the depilatory device 2, the circuit device 3 and the power supply device 4 generate heat.

[0016] In daily production, several control elements (not shown in the figure) are generally arranged on a surface of the housing 1 within the circuit device 3, forming a switch, a screen, and a control panel. The user can control the entire portable hair removal device 100 by manipulating these elements to turn it on / off and adjust the levels.

[0017] The depilatory device 2 is located at one end near the head section 12 of the housing 1 and can be firmly clamped within the receiving space of the housing 1. An inlet 11 and a second outlet 14, corresponding to a section of the depilatory device 2, are located on one side of the housing 1, i.e., the upper housing 101 or the lower housing 102. It is understood that both the inlet 11 and the second outlet 14 are located on the same side of the housing 1 and are positioned close together. This design serves to save space within the housing 1, allowing the housing 1 to be relatively shorter and more compact and precise. The inlet 11 and the second outlet 14 are designed together to shorten the air circulation distance, thus implementing rapid air circulation and increasing heat dissipation efficiency.

[0018] Furthermore, the first outlet 15 is located at an end section of the housing 1, i.e., at an end of the housing 1 furthest from the head section 12. The reason for this furthest location of the first outlet 15 is to increase the distance through which the air flows, thus creating a wider cooling area.

[0019] It is understood that in normal production, both the circuit device 3 and the power supply device 4 are arranged within the housing 1 and optionally within the holding section 13. In this embodiment, both the circuit device 3 and the power supply device 4 are arranged on the rear side of the hair removal device 2, i.e., on the side of the hair removal device 2 facing away from human skin. Using this design increases the area of ​​the air involved in order to achieve an overall cooling effect within the housing 1.

[0020] In relation to Fig. Figure 3 of the hair removal device 2 comprises a heat dissipation mechanism 21 and a hair removal mechanism 22. The hair removal mechanism 22 emits light to remove hair from the human body and is primarily in contact with the human skin. The heat dissipation mechanism 21 is used to reduce the temperature so that the human body does not experience a burning sensation under the light. The heat dissipation mechanism 21 and the hair removal mechanism 22 can be connected by a clamp connection or a screw connection, or are optionally connected by a screw connection for a more stable fixation.

[0021] In relation to Fig. Figure 4 of the heat dissipation mechanism 21 comprises a fan 211 and a heat-conducting component 212. The fan 211 can be a radial, axial, mixed-flow, or cross-flow fan, or optionally a radial fan, so that external air flows mainly radially after entering an impeller of the fan 211 axially. The heat-conducting component 212 and the fan 211 can be connected by a screw connection or clamp connection, so that the air drawn in by the fan 211 can flow through the heat-conducting component 212 in a split direction. The depilatory mechanism 22 is connected to a surface of the heat-conducting component 212 remote from the fan 211, and therefore an airflow in the heat-conducting component 212 can cool and reduce the temperature at the demodulation mechanism 22 to achieve an ice-compress effect on human skin. With reference to Fig. 1 and Fig. 5, a specific structure of the fan 211 is as follows:

[0022] The fan 211 has a fan air inlet 2111 and a fan air outlet 2112. A first heat dissipation fin 2114 is arranged at the fan air inlet 2111, and the first heat dissipation fin 2114 is arranged at an end section of the heat-conducting element 2113. That is, the heat-conducting element 2113 is located at one end near the fan air inlet 2111, and the fan 211 is arranged at one end of the fan air inlet 2111 that faces the inlet 11 on the housing 1 in order to draw air through the interior of the inlet 11 on the housing 1, with the first heat dissipation fin 2114 completely covering the fan air inlet 2111, so that the external air passes through the first heat dissipation fin 2114 for heat dissipation and temperature reduction for the first time before entering the fan air inlet 2111.A section of the heat-conducting element 2113 is inserted into the first heat dissipation rib 2114, and a remaining section extends outwards.

[0023] Furthermore, the first heat dissipation fin 2114 can be a cast iron heat dissipation fin, a steel heat dissipation fin, and / or a heat dissipation fin made of an aluminum alloy. It is understood that, since the first heat dissipation fin 2114 dissipates heat in the form of convection, a larger coverage area indicates a better heat dissipation effect.

[0024] Furthermore, the heat-conducting element 2113 can be a heat-conducting tube, and the material of the heat-conducting element is selected as a sheet structure or a tubular structure made of a metal or alloy such as silver, copper, or iron, or is optionally a sheet structure. Due to a unique metal heat transfer property, the heat-conducting element 2113 can dissipate heat integrally through the first heat dissipation fin 2114.

[0025] It is understood that in actual production, the first heat dissipation fin 2114 and the heat-conducting element 2113 often have an integrated structure and are connected to each other. Under the effect of metal heat transfer, when the fan 211 draws air inwards, the heat flows rapidly along the heat-conducting element 2113, thus implementing a rapid temperature reduction.

[0026] In relation to Fig. 6. The heat-conducting component 212 has a first vent opening 2121. The first vent opening 2121 is arranged at an end of the heat-conducting component 212 facing the fan 211, or the first vent opening 2121 is optionally arranged parallel to an end of the heat-conducting component 212, so that after entering through the first vent opening 2121 on one side, the external cooling medium is expelled in the opposite direction from the first vent opening 2121 on the other side. Additionally, a second heat dissipation fin 2123 is arranged on a surface on one side of the heat-conducting component 212, and the second heat dissipation fin 2123 is optionally arranged on an upper side of the heat-conducting component 212.

[0027] In relation to Fig. 7 The depilatory mechanism 22 comprises a cold compression section 221, an emitter 222, a cooling element 223, a skin detection section 224, a reflector plate 225, an insulating plate 226 and a mounting component (not marked).

[0028] Both the emitter 222 and the cooling element 223 are electrically connected to the circuit device 3, the cold compression section 221 is clamped to the mounting component, the cooling element 223 is firmly attached to the cold compression section 221 to cool the cold compression section 221, the insulating plate 226 is arranged between the cold compression section 221 and the emitter 222 to prevent heat from the emitter 222 from being transferred to the cold compression section 221, and the reflector plate 225 is arranged on one side of the emitter 222 away from the cold compression section 221 so that light emitted by the emitter 222 is concentrated onto the cold compression section 221.

[0029] Furthermore, the cold compression section 221 is made of a crystalline material and can in particular be made of sapphire, K9 glass or crystal glass, provided that a transparent crystalline material is used. Optionally, the cold compression section is made of a sapphire material.

[0030] It is understood that, since the cold compression section 221 is made of sapphire, it can be used as a light outlet. When the emitter 222 emits light, the cooling element 223 and the cold compression section 221, which are firmly attached to a surface of the emitter 222, can efficiently generate heat exchange due to the relatively high thermal conductivity of the sapphire to achieve optimal cooling. The cold compression section 221 made of sapphire can be round or rectangular; this is not limited here. A surface of the cold compression section 221 away from the emitter 222 is in contact with the human body, and this contact surface can be an arcuate surface or a flat surface, preferably a flat surface.

[0031] Furthermore, the emitter 222 can be an IPL tube and is located on one side of the cold compression section 221, away from contact with the human body. The light emitted by the emitter 222 penetrates the cold compression section 221 and is emitted into the user's skin. The color of the light emitted by the emitter 222 is not limited. The light can be colored, composite, or otherwise, and a specific wavelength and frequency are determined according to the application.

[0032] Furthermore, the skin detection section 224 is electrically connected to the circuit device 3 using a capacitive touch detection principle. When the cold compression section 221 is in contact with the skin, an internal preset capacitance detection device detects whether a machine is actually in contact with the skin in order to reduce / resolve a safety problem caused by user error.

[0033] Furthermore, the shape of the reflector plate 225 is not restricted, provided that the light from the emitter 222 is concentrated in one direction towards the cold compression section 221. The reflector plate 225 can optionally be U-shaped, with one opening of the reflector plate 225 facing the cold compression section 221, and the emitter 222 located in the center of the opening of the U-shaped reflector plate 225. In addition to concentrating the light, the reflector plate 225 also prevents heat from the emitter 222 from being dissipated to other locations during operation.

[0034] In relation to Fig. 8 The reflector plate 225 is clamped to the heat-conducting component 212 and positioned on a surface away from the first vent opening 2121, such that the first vent opening 2121 forms a sealed channel. With respect to Fig. 8 and Fig. 9. When connecting the fan 211 and the heat-conducting component 212 through the fan air outlet 2112, they are placed onto the first vent opening 2121. Since a dimension a of the fan air outlet 2112 is larger than a dimension b of the first vent opening 2121, an additional gap c forms a second vent opening 2122, so that the air is divided in two directions into the first vent opening 2121 and the second vent opening 2122.

[0035] In relation to Fig. 11 and Fig. 12 furthermore, when the fan 211 and the heat-conducting component 212 are connected, the heat-conducting element 2113 is firmly attached to the cooling element 223 on the fan 211, and the first vent opening 2121 is exposed on one side of the fan 211 to expel the air drawn in by the fan 211.

[0036] In relation to Fig. 11 and Fig. 13 The cooling element 223 is optionally a cooling element 223 in a semiconductor cooling mode, the cooling element 223 has a heating surface 2231 and a cooling surface 2232 which are arranged opposite each other, and the cooling surface 2232 of the cooling element 223 is fixedly attached to the cold compression section 221 in order to cool the cold compression section 221.

[0037] It is understood that, due to the nature of the light-based hair removal technology, a significant amount of heat is generated when the light is emitted. Therefore, when the cold compression section 221 comes into contact with the skin, a temperature reduction structure must be incorporated within the body of the portable hair removal device 100 to prevent the light from causing a burning sensation for the user. Regardless of the method of temperature reduction, the heat is generated through heat exchange, and the heating surface 2231 of the cooling element 223 is connected to the heat-conducting element 2113. In addition to the cooling element 223, other internal components, such as the emitter 222, the power supply unit 4, and the circuitry 3 within the housing 1, also generate considerable heat.

[0038] If the heat is not dissipated in time, the cooling element 223 cannot achieve the cooling effect with maximum efficiency, thus failing to reach a cooling temperature at which the skin is temporarily paralyzed.

[0039] In relation to Fig. 13, Fig. 14 and Fig. 15 is, according to the two directions of the first vent 2121 and the second vent 2122 above, one of the directions of the air is the first vent 2121, and the first vent 2121 is connected to the first outlet 15 on the housing 1 to form a first channel A in which the air flows.

[0040] It is understood that the external air is drawn in through the inlet 11. After entering through the first vent 2121, the external air passes through the emitter 222 to reduce its temperature, then passes through the circuit device 3 and the power supply device 4 inside the housing 1, and is expelled through the first outlet 15 of the housing 1 to form the first duct air path. Furthermore, temperature reduction and cooling also occur in the areas through which the air flows. For example, the circuit device 3 and the power supply device 4 are located in the airflow area, i.e., on one side of the interior of the housing 1 near the first outlet 15, to dissipate heat from the circuit device 3 and the power supply device 4 and to expel the air through the first outlet 15.

[0041] The heat-conducting component 212 and the second heat-dissipation fin 2123 at an upper end of the heat-conducting component are integrated. An outer surface of the heat-conducting component 212 and an inner wall of the housing 1 are enclosed to form a space, and a second vent opening 2122 is formed at the fan air inlet 2111 in a mounting manner. The second heat-dissipation fin 2123 is arranged in the space and faces the second outlet 14, so that the air exits in the direction of the second outlet 14. Therefore, the second vent opening 2122 and the second outlet 14 on the housing 1 form a second channel B.

[0042] It is understood that the second heat dissipation fin 2123 not only has a heat dissipation function but also a function of guiding airflow. Based on this, the second heat dissipation fin 2123 is designed as a fin structure so that internal air can exit directly towards the second outlet 14. As it passes through the second heat dissipation fin 2123, the air flows over the cooling element 223 to reduce its temperature. The reason the air is expelled directly is that the cooling element 223 is a component that generates a maximum amount of heat within the portable hair removal device 100. Therefore, the airflow path must be reduced in the air circulation, so that the air is expelled immediately, thus achieving the cooling and temperature reduction effect with maximum efficiency.

[0043] Based on the first channel A and the second channel B, in some embodiments, one way of heat dissipation may not be the use of the fan 211 for air cooling, but an external cooling medium such as water or coolant may be used, provided that the external medium can dissipate heat from the two channels.

[0044] Based on the first channel A and the second channel B, in some embodiments the heat dissipation mechanism 21 may not have the heat-conducting element 2113 and the first heat dissipation fin 2114 and may carry out heat dissipation at the emitter 222 and the cooling element 223 by directly using air from the fan 211 or another medium.

[0045] The second outlet 14 is arranged on one side of the inlet 11. Both are arranged on a side surface of the housing 1 near one end of the heat-conducting element 2113, and the first outlet 15 is located at an end section of the housing 1 away from the heat-conducting element 2113, so that air of the first channel A is able to flow completely through the interior of the entire housing 1, and an air inlet direction of the inlet 11 is parallel to an air outlet direction of the second outlet 14 and perpendicular to an air outlet direction of the first outlet 15.

[0046] A contact end surface between the cold-compression section 221 and the skin is located on the same side as an end surface where the skin detection section 224 is exposed. This ensures that, when light hair removal is performed, the cold-compression section 221 is in contact with a perimeter of the irradiated skin to cool and reduce the temperature at that perimeter, thereby alleviating any burning sensation. Additionally, the cold-compression section 221 can operate at near-zero temperatures to bring the skin near the light outlet extremely close to freezing, thus relieving the burning sensation and preventing skin damage from brief contact.

[0047] Guided by the second heat dissipation fin 2123, air entering the second vent 2122 is expelled directly from the first outlet 15 after passing through the heat-conducting element 2113. In this way, an air path of the second channel B is formed, and temperature reduction and cooling are achieved in the areas through which the air flows.

[0048] In the present disclosure, an improvement is made to a portable hair removal device 100 using an original heat dissipation mode.The fan 211 is used to draw in external air. Air flows through the heat-conducting component 212 in a separate direction to the first channel A and the second channel B. The first channel A and the second channel B are completely insulated. The cooling element 223 and the emitter 222 are each located in positions through which the first channel A and the second channel B pass. As the air flows through the completely insulated first channel A and second channel B, heat dissipation is carried out separately at the cooling element and the emitter. Furthermore, the first channel A can reduce the temperature of other heat-generating elements within the housing 1, such as the circuit device 3 and the power supply device 4, to achieve efficient and complete temperature reduction and cooling.

[0049] In some embodiments, a plurality of channels is provided, more than the two channels in this embodiment. With the exception of the cooling element 223 and the emitter 222, a plurality of channels may alternatively be provided, and other heat-generating elements may alternatively be arranged in the remaining channels. This falls within the scope of protection of the present disclosure.

[0050] In some embodiments, a portable hair removal device 100 is provided with a light-emitting body (not shown in the figure), and structural features are used that are described in all the preceding embodiments. Example 2:

[0051] To better solve the aforementioned problem of incomplete heat dissipation, the present disclosure further provides a second embodiment. The second embodiment is an extension of the portable hair removal device 100 in the first embodiment and includes all features of the portable hair removal device 100 in the first embodiment.

[0052] In relation to Fig. 16 and Fig. 17 The portable hair removal device 100, which is provided in the second embodiment, is provided with a third outlet 16 on the housing 1, and the third outlet 16 is optionally arranged on a peripheral side of the first vent opening 2121 and is connected to a cavity inside the housing 1, so that the external cooling medium can be expelled from the first vent opening 2121 through the third outlet 16 on the peripheral side of the housing 1.

[0053] Furthermore, in the present disclosure, the upper housing 101 and the lower housing 102 are optionally arranged at a first groove 1601 and a second groove 1602, an outlet structure capable of communicating with the interior of the housing 1 is arranged between the first groove 1601 and the second groove 1602, and after the upper housing 101 and the lower housing 102 are connected, a gap is formed between the first groove 1601 and the second groove 1602, and the outlet structure is arranged in the gap to cause the cavity inside the housing 1 to communicate with the outside to form a third outlet 16.

[0054] In relation to Fig. 18 and Fig.Furthermore, the heat-conducting component 212 is provided with a third vent opening 2124 on the second heat dissipation fin 2123, the third vent opening 2124 is oriented towards a guide direction of the second heat dissipation fin 2123, i.e., towards a direction of the second outlet 14, and the third vent opening 2124 is connected to the first vent opening 2121, so that the external cooling medium is expelled through the third vent opening 2124 in a direction from the second heat dissipation fin 2123 to the second outlet 14 after passing through the first vent opening 2121, in order to better accelerate the progress of the heat exchange, thereby achieving a better cooling effect on the dehairing mechanism 2.

[0055] The third vent 2124 is merely a means of implementing communication with the first vent 2121, and there are no limitations on the number or method of communication. That is to say, alternatively, a fourth or fifth vent may be provided, or the heat-conducting component 212 may be provided with at least three through-holes on a surface of the second heat dissipation fin 2123, such that the vent communicates with the first vent 2121, provided that the external cooling medium flowing within the first vent 2121 is expelled through the second heat dissipation fin 2123.

[0056] Therefore, the cooling effect is further improved by the first vent 2121 and the second vent 2122 and under the action of the first outlet 15, the second outlet 14, the third outlet (not shown in the figure), the first vent 2121, the second vent 2122 and the third vent 2124, thus providing the user with a better ice sensation experience.

[0057] As summarized in Exemplary Example 2, the outlets arranged on the housing 1 and the vents on the dehairing mechanism are mainly described in this exemplary embodiment. The number of outlets and the number of vents are unlimited. For example, the third outlet 16 is mainly used to expel the external cooling medium passing through the first vent 2121 to the outside of the housing 1, or the third vent 2124 is mainly used to expel the external cooling medium passing through the first vent 2121 through the second heat dissipation fin 2123 to the outside of the housing 1.

[0058] A person skilled in the art should also understand that if all or some of the components of the structure in the present disclosure are combined in a manner of fusion, physical connection or the like, for example, if positions of the components in the depilatory device 2 are moved; or if the components are integrated; or if the components are designed to be detachable; and if a feature size is exchanged and a feature morphology is changed that is not used as a function, all the combined components can form a device / apparatus with a specific function, and such a device / apparatus replaces a corresponding component in the present disclosure and also falls within the scope of protection of the present disclosure.

[0059] Compared to the prior art, the portable hair removal device 100 provided in the present disclosure has the following advantages. To make it easier for users to hold, all portable household hair removal devices are designed to be relatively small. Therefore, due to the accumulation of a large amount of heat, heat dissipation is a very important issue, and if the heat dissipation is insufficient, users may experience pain during hair removal, and it may even create a safety hazard. Previously, only a single inlet and outlet were provided in the portable hair removal device to form a channel for heat dissipation. However, it is not just a single element that generates heat within the portable hair removal device.However, if a multitude of heat-generating elements rely on a single channel formed by an inlet and an outlet for heat dissipation, the heat generated by the heat-generating elements affects each other, resulting in poor heat dissipation and impacting the operating environment of the heat-generating elements within the channel. For example, the cooling element and the emitter, both of which generate heat, are placed in the same heat dissipation channel. As the external cooling medium passes through both the cooling element and the emitter, it carries the heat to a different location. Therefore, in the present disclosure, a multitude of heat dissipation channels are provided in the portable hair removal device 100, and different heat-generating elements can be arranged in different heat dissipation channels.The heat dissipation channel can be an inlet corresponding to a multitude of outlets, or it can be a multitude of inlets corresponding to a single outlet. Therefore, under the influence of the heat-conducting component, the external cooling medium can cool a multitude of heat-generating elements within the housing 1 of the portable hair removal device 100 without interfering with each other.

[0060] The foregoing descriptions are only preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modification, equivalent replacement, or improvement made without departing from the principle of the present disclosure falls within the scope of protection of the present disclosure.
