Description

Technical Field

[0001] This application relates to the field of nursing equipment technology, and more particularly to a hand tool. Background Technology

[0002] A beauty device is a portable or home-use device that uses modern technology (such as light, electricity, sound waves, and heat energy) to care for and treat the skin. Through specific technical means, it helps improve skin problems, delay aging, and enhance skin texture, serving as a beauty tool that falls between professional medical aesthetics and daily skincare.

[0003] Existing beauty devices have limited functions; some are suitable for removing blemishes, while others are suitable for skin rejuvenation or hair removal.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0050] like Figures 1 to 4 As shown, some embodiments of this application provide a hand tool having intersecting first direction X and second direction Y, mainly used for skin care, improving the care effect and the diversity of care to meet the care needs of different users.

[0051] The handpiece includes a housing 100, a frame 200, a first light-emitting component 300, and a second light-emitting component 400.

[0052] The housing 100 defines a receiving cavity 110. The housing 100 has a light-transmitting part 120 at one end along the second direction Y. In this embodiment, the light-transmitting part 120 is disposed on the side of the housing 100 facing the first direction X, so that the laser emitted by the first light-emitting component 300 and / or the second light-emitting component 400 can pass through the light-transmitting part 120 to care for the user's skin.

[0053] The frame 200 is disposed in the receiving cavity 110 and is connected to the inner wall of the housing 100. The connection method between the frame 200 and the inner wall of the housing 100 includes any one or a combination of two or more of the following: snap-fit, adhesive, magnetic connection, threaded connection, and bolted connection, which can be specifically set according to the actual situation.

[0054] In this embodiment, the frame 200 is disposed close to the light-transmitting part 120, and there is a gap between the frame 200 and the light-transmitting part 120 along the second direction Y.

[0055] The frame 200 is provided with a first light-transmitting hole 210 and a second light-transmitting hole 220 extending along the second direction Y. The first light-transmitting hole 210 and the second light-transmitting hole 220 are arranged at intervals, and the first light-transmitting hole 210 and the second light-transmitting hole 220 respectively face the light-transmitting part 120. It can be understood that the axis of the first light-transmitting hole 210 is parallel to the axis of the second light-transmitting hole 220.

[0056] The projections of the first light-transmitting hole 210 and the second light-transmitting hole 220 onto the plane of the light-transmitting part 120 are located in the light-transmitting part 120, thereby ensuring that the light passing through the first light-transmitting hole 210 and the second light-transmitting hole 220 can pass through the light-transmitting part 120 along the second direction Y, thereby reducing the scattering of the first laser and the second laser.

[0057] The first light-emitting component 300 and the second light-emitting component 400 are respectively disposed on two opposite sides of the frame 200 along the first direction X, so as to separate the first light-emitting component 300 and the second light-emitting component 400 by the frame 200, prevent the first light-emitting component 300 and the second light-emitting component 400 from affecting each other during operation, thereby ensuring the stability of both during operation.

[0058] The first light-emitting component 300 can emit a first laser, which can pass through the first light-transmitting hole 210 and the light-transmitting part 120. The second light-emitting component 400 can emit a second laser, which can pass through the second light-transmitting hole 220 and the light-transmitting part 120, so as to care for the user's skin through the first laser and the second laser.

[0059] It should be noted that by providing a first light-transmitting hole 210 and a second light-transmitting hole 220 on the frame 200, the divergence angle of the first laser is limited by the hole wall of the first light-transmitting hole 210, making the first laser beam more concentrated and collimated, improving the directivity and focusing effect of the first laser, and also blocking unnecessary stray light to prevent the first laser from scattering in non-target directions. Similarly, by limiting the divergence angle of the second laser by the hole wall of the second light-transmitting hole 220, the divergence angle of the second laser beam is also limited, making the second laser beam more concentrated and collimated, improving the directivity and focusing effect of the second laser, and also blocking unnecessary stray light to prevent the second laser from scattering in non-target directions.

[0060] In this embodiment, the first direction X is perpendicular to the second direction Y. In some embodiments, the wavelength of the first laser is less than or equal to the wavelength of the second laser. It is understood that the handpiece provided by this application can emit two wavelengths of laser light to provide skin care for different users, thereby achieving precise care. Furthermore, the wavelengths of the first and second lasers in the handpiece provided by this application can also be equal to meet the user's skin care needs.

[0061] In this embodiment, the wavelength of the first laser is 755nm, and the wavelength of the second laser is 808nm. It should be noted that the 755nm laser is highly absorbed by melanin, which can precisely destroy hair follicles, making it suitable for removing dark hair with minimal damage to surrounding tissues. It can also be used to treat pigmented skin diseases such as freckles and sunspots, and can effectively decompose melanin.

[0062] In addition, 808nm lasers penetrate deeper and are suitable for coarser hair and darker skin types, but the absorption rate of melanin is lower than that of 755nm. They are used to stimulate collagen regeneration and improve skin texture. They have some absorption of hemoglobin and can be used to treat vascular skin diseases such as telangiectasia. They can also be used for deep tissue therapy to promote blood circulation and tissue repair.

[0063] It is understood that by setting a first light-emitting component 300 and a second light-emitting component 400 in the handpiece, and the first light-emitting component 300 can emit a first laser, and the second light-emitting component 400 can emit a second laser, and the wavelength of the first laser is shorter than the wavelength of the second laser, the user can select the appropriate wavelength of laser according to their own needs, thereby achieving precise care and improving the user's experience.

[0064] like Figure 2 and Figure 5 As shown, in some embodiments of this application, the first light-emitting component 300 includes a first heat-conducting plate 310, a first connecting plate 320, and a first light-emitting chip 330.

[0065] It should be noted that the first light-emitting chip 330 is capable of emitting the first laser.

[0066] The first heat-conducting plate 310 is disposed on one side of the frame 200 along the first direction X, and the side of the first heat-conducting plate 310 facing the frame 200 is attached to the frame 200 to increase the contact area between the first heat-conducting plate 310 and the frame 200, thereby improving the heat conduction efficiency between the first heat-conducting plate 310 and the frame 200.

[0067] In addition, the first light-emitting chip 330 is disposed between the first heat-conducting plate 310 and the first connecting plate 320. The first connecting plate 320 is disposed on the side of the first light-emitting chip 330 away from the first heat-conducting plate 310, so that the first connecting plate 320 and the first heat-conducting plate 310 can limit the first light-emitting chip 330, thereby ensuring the stability of the first light-emitting chip 330 between the first connecting plate 320 and the first heat-conducting plate 310.

[0068] The connection method between the first connecting plate 320 and the second connecting plate 420 includes any one of the following: snap-fit, adhesive, magnetic connection, threaded connection, and bolt connection.

[0069] It should be noted that the first connecting plate 320 has a first gap on the side facing the light-transmitting part 120 and the first heat-conducting plate 310 has a first gap on the side facing the light-transmitting part 120, so that the first laser emitted by the first light-emitting chip 330 can pass through the first gap and enter the first light-transmitting hole 210.

[0070] In this embodiment, the first light-emitting chip 330 is attached to the first heat-conducting plate 310 on the side facing the first heat-conducting plate 310 to improve the heat conduction efficiency between the first light-emitting chip 330 and the first heat-conducting plate 310.

[0071] like Figure 2 and Figure 5 As shown, in some embodiments of this application, the second light-emitting component 400 includes a second heat-conducting plate 410, a second connecting plate 420, and a second light-emitting chip 430.

[0072] It should be noted that the second light-emitting chip 430 is capable of emitting a second laser.

[0073] The second heat-conducting plate 410 is disposed on one side of the frame 200 along the first direction X, and the side of the second heat-conducting plate 410 facing the frame 200 is attached to the frame 200 to increase the contact area between the second heat-conducting plate 410 and the frame 200, thereby improving the heat conduction efficiency between the second heat-conducting plate 410 and the frame 200.

[0074] In addition, the second light-emitting chip 430 is disposed between the second heat-conducting plate 410 and the second connecting plate 420. The second connecting plate 420 is disposed on the side of the second light-emitting chip 430 away from the second heat-conducting plate 410, so that the second light-emitting chip 430 is limited by the second connecting plate 420 and the second heat-conducting plate 410 to ensure the stability of the second light-emitting chip 430 between the second connecting plate 420 and the second heat-conducting plate 410.

[0075] The connection method between the second connecting plate 420 and the second connecting plate 420 includes any one of snap-fit, adhesive, magnetic connection, threaded connection, and bolt connection.

[0076] It should be noted that the second connecting plate 420 has a second gap on the side facing the light-transmitting part 120 and the second heat-conducting plate 410 has a second gap on the side facing the light-transmitting part 120, so that the second laser emitted by the second light-emitting chip 430 can pass through the second gap and enter the second light-transmitting hole 220.

[0077] In this embodiment, the second light-emitting chip 430 is attached to the second heat-conducting plate 410 on the side facing the second heat-conducting plate 410 to improve the heat conduction efficiency between the second light-emitting chip 430 and the second heat-conducting plate 410.

[0078] like Figures 2 to 4 As shown, in some embodiments of this application, the frame 200 is provided with a third light-emitting component 800 on the side facing the light-transmitting part 120.

[0079] In this embodiment, the third light-emitting component 800 includes a control board and a plurality of LED chips 820, which are electrically connected to the control board 810. The number of LED chips 820 can be any number of two or more values, and can be specifically set according to actual conditions.

[0080] In some embodiments of this application, the number of LED chips 820 is five.

[0081] In addition, the control board 810 is disposed on the side of the frame 200 facing the light-transmitting part 120, and a plurality of LED chips 820 are disposed at intervals on the side of the control board 810 facing the light-transmitting part 120, so as to control the LED chips 820 through the control board 810.

[0082] It should be noted that the LED chip 820 emits light of a specific wavelength via the control board 810 to achieve beauty and skincare effects. In this embodiment, the light emitted by the LED chip 820 can inhibit melanin production and accelerate skin metabolism, thereby improving the user's skin. Furthermore, by combining LED chips 820 with different wavelengths, various beauty effects can be achieved to meet the care needs of different skin types, thus enhancing the user experience.

[0083] like Figures 3 to 5 As shown, in some embodiments of this application, the housing 100 has a third direction Z that intersects the first direction X and the second direction Y in pairs. Along the third direction Z, one end of the housing 100 is provided with an air inlet 130 communicating with the receiving cavity 110, and the other end of the housing 100 is provided with an air outlet 140 communicating with the receiving cavity 110, so that external gas can enter the receiving cavity 110 through the air inlet 130 and be discharged from the air outlet 140, thereby forming an airflow channel inside the housing 100.

[0084] The cavity 110 is equipped with a fan 600, which has an air inlet 610 and an air outlet 620. The air inlet 610 faces the air inlet 130, and the air outlet 620 faces the air outlet 140. This allows the fan 600 to create a negative pressure at the air inlet 130 during operation, so that external gas can enter the cavity 110 through the air inlet 130. The gas entering the cavity 110 passes through the air inlet 610, the air outlet 620 and the frame 200 in sequence, and is discharged from the air outlet 140.

[0085] It is understandable that by adjusting the operating power of the fan 600 to regulate the flow rate of gas in the receiving cavity 110, the heat dissipation efficiency of the hand tool can be adjusted, thereby achieving the purpose of controlling the hand tool temperature.

[0086] like Figure 2 As shown, in some embodiments of this application, the handpiece further includes a radiator 700, which is connected to the light-transmitting portion 120. The radiator 700 defines a plurality of heat dissipation channels 710. It can be understood that by increasing the number of heat dissipation channels 710, the contact area between the gas flowing through the airflow channel and the radiator 700 is increased, thereby improving the heat conduction efficiency and thus improving the heat dissipation efficiency.

[0087] The axis of the heat dissipation channel 710 is parallel to the axis of the airflow channel to improve the smoothness of airflow in the heat dissipation channel 710 and ensure the quality of heat dissipation.

[0088] like Figure 2 and Figure 5 As shown, in some embodiments of this application, the heat sink 700 includes a first heat dissipation component 720.

[0089] The first heat dissipation component 720 includes a semiconductor dielectric 721, a cooling chip 722, at least one first heat pipe 723, and a plurality of first heat sinks 724, which are arranged at intervals along the second direction Y. The distance between two adjacent first heat sinks 724 can be specifically set according to actual conditions.

[0090] In this embodiment, a plurality of first heat sinks 724 are arranged at equal intervals along the second direction Y to ensure the uniformity of the heat dissipation efficiency of each first heat sink 724, thereby ensuring the stability of heat dissipation.

[0091] It is understandable that the number of the first heat pipe 723 can be one, two or more, depending on the specific circumstances.

[0092] In addition, the semiconductor medium 721 is disposed on the side of the light-transmitting portion 120 facing the frame 200, the semiconductor medium 721 is disposed between the light-transmitting portion 120 and the cooling chip 722, the semiconductor medium 721 surrounds the light-transmitting portion 120, and there is a gap between the side of the semiconductor medium 721 facing the light-transmitting portion 120 and the light-transmitting portion 120.

[0093] In this embodiment, the cooling chip 722 is disposed on the side of the semiconductor dielectric 721 away from the light-transmitting portion 120. The cooling chip 722 is provided with a light-transmitting opening 7222 through the second direction Y. The light-transmitting opening 7222 faces the light-transmitting portion 120 so that the light emitted by the first light-emitting component 300, the second light-emitting component 400 and the third light-emitting component 800 can pass through the light-transmitting opening 7222 and irradiate the light-transmitting portion 120. The light-transmitting opening 7222 forms a clearance effect to avoid blocking the light.

[0094] In addition, one end of the first heat pipe 723 is connected to the side of the cooling chip 722 away from the semiconductor medium 721, and the other end of the first heat pipe 723 is inserted through a plurality of the first heat sinks 724, so as to conduct the heat generated by the cooling chip 722 through the first heat pipe 723 and conduct it to the first heat sinks 724, so as to control the temperature of the cooling chip 722.

[0095] It should be noted that there is a gap between the cooling element 722 and the light-transmitting element 500.

[0096] In this embodiment, there are multiple first heat pipes 723, which are spaced apart. Increasing the number of first heat pipes 723 increases the contact area between the first heat pipe and the first heat sink 724, thereby improving the heat transfer efficiency between them. It also increases the contact area between the first heat pipe 723 and the cooling element 722, further improving their heat transfer efficiency. This allows the first heat pipes 723 and the first heat sink 724 to dissipate heat from the cooling element 722, ensuring the temperature stability of the cooling element 722. It is understood that by increasing the heat transfer efficiency between the cooling element 722, the first heat pipes 723, and the first heat sink 724, the gas flowing through the first heat sink 724 can carry away heat from its surface, thereby reducing the surface temperature of the first heat sink 724 and achieving heat dissipation.

[0097] In this embodiment, the cooling chip 722 is a TEC (Thermoelectric Cooler) cooling chip. TEC cooling chips are characterized by their small size and high temperature control accuracy, which can effectively improve the accuracy of temperature control.

[0098] like Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments of this application, the heat sink 700 further includes a second heat dissipation component 730, which includes at least one second heat pipe 731 and a plurality of second heat dissipation fins 732 arranged at intervals along the second direction Y. It is understood that the number of second heat pipes 731 can be one, two, or more, and can be specifically set according to the actual situation.

[0099] The frame 200 has a through-hole 230 along the second direction Y. One end of the second heat-conducting pipe 731 is disposed in the through-hole 230, and the outer wall of the second heat-conducting pipe 731 is attached to the wall of the through-hole 230 to increase the contact area between the second heat-conducting pipe 731 and the wall of the through-hole 230, thereby improving the heat transfer efficiency between the frame 200 and the second heat-conducting pipe 731. It is understood that the second heat-conducting pipe 731 can dissipate heat from the frame 200 to control the temperature of the frame 200.

[0100] Furthermore, the other end of the second heat pipe 731 is inserted into the plurality of second heat sinks 732, so that the heat from the second heat pipe 731 can be conducted to the second heat sinks 732, thus forming heat conduction. It can be understood that by increasing the number of second heat sinks 732, the heat conduction efficiency between the second heat pipe 731 and the second heat sinks 732 can be improved.

[0101] It should be noted that, along the third direction Z, one side of the hole wall of the mounting hole 230 is adjacent to the first heat-conducting plate 310, and the other side of the hole wall of the mounting hole 230 is adjacent to the second heat-conducting plate 410. The first heat-conducting plate 310 and the first light-emitting chip 330 are connected, as are the second heat-conducting plate 410 and the second light-emitting chip 430, so that the heat generated by the first light-emitting chip 330 can be conducted to the first heat-conducting plate 310, and the heat generated by the second light-emitting chip 430 can be conducted to the second heat-conducting plate 410, thus forming heat conduction. Understandably, the first heat-conducting plate 310 and the second heat-conducting plate 410 can respectively conduct heat to the frame 200 and transfer heat to the frame 200. Since the frame 200 is connected to the second heat-conducting pipe 731, the heat in the frame 200 is carried out through the second heat-conducting pipe 731 and transferred to the second heat sink. When the gas flows over the surface of the second heat sink 732, it can carry away the heat of the second heat sink 732 and discharge it from the gas outlet, thereby realizing the heat dissipation of the first light-emitting chip 330 and the second light-emitting chip 430, so as to ensure the temperature stability of the first light-emitting chip 330 and the second light-emitting chip 430 and improve the service life of the first light-emitting chip 330 and the second light-emitting chip 430.

[0102] It should be noted that the first heat dissipation component 720 dissipates heat from the cooling chip 722 to ensure the temperature stability of the cooling chip 722. The second heat dissipation component 730 dissipates heat from the first light-emitting chip 330 and the second light-emitting chip 430 to control the temperature of the first light-emitting chip 330 and the second light-emitting chip 430, ensuring the stability of the first light-emitting chip 330 and the second light-emitting chip 430, and thus extending their service life. By setting the first heat dissipation component 720 and the second heat dissipation component 730, and by having a gap between the first heat dissipation fin 724 and the second heat dissipation fin 732, the first heat dissipation component 720 and the second heat dissipation component 730 do not interfere with each other, thereby ensuring the stability of heat dissipation for the first light-emitting chip 330, the second light-emitting chip 430, and the cooling chip 722, and improving the heat dissipation quality.

[0103] like Figure 2 and Figure 4 As shown, in some embodiments of this application, the light-transmitting portion 120 is provided with an optical film 1000 on the side facing the frame 200, and the optical film 1000 completely covers the light-transmitting portion 120 along the second direction Y.

[0104] It should be noted that the optical film 1000 can reduce light loss during transmission, ensuring that more effective light energy reaches the skin. The optical film can also filter out harmful light rays such as ultraviolet (UV) or infrared (IR) rays, ensuring that only light of specific wavelengths (such as red light and blue light) is used for treatment, thereby achieving efficient and precise phototherapy.

[0105] like Figure 5 and Figure 7 As shown, in some embodiments of this application, the edge of the cooling chip 722 is provided with a plurality of connection holes 7221, which penetrate the cooling chip 722 along the second direction Y.

[0106] In this embodiment, there are four connection holes 7221, which are respectively located at the four apex corners of the cooling chip 722. The walls of each connection hole 7221 are provided with a heat insulation layer 900, which completely covers the walls of the connection holes 7221.

[0107] In addition, the frame 200 is provided with a plurality of support feet 240 on the side facing the cooling chip 722. It should be noted that the number of support feet 240 is equal to the number of connection holes 7221, and one support foot 240 is partially inserted into one connection hole 7221, connecting the support foot 240 to the heat insulation layer 900, so that the heat insulation layer 900 forms a heat insulation effect between the frame 200 and the cooling chip 722, thereby preventing heat conduction from occurring between the cooling chip 722 and the frame 200.

[0108] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments of this application, a light-transmitting element 500 is provided between the frame 200 and the light-transmitting part 120. The light-transmitting element 500 completely covers the first light-transmitting hole 210 and the second light-transmitting hole 220 along the second direction Y, so that the first laser passing through the first light-transmitting hole 210 or the second laser passing through the second light-transmitting hole 220 can be incident on the light-transmitting element 500 and pass through the light-transmitting element 500. The cooling plate 722 surrounds the light-transmitting element 500, and there is a gap between the cooling plate 722 and the light-transmitting part 120 to prevent heat conduction from occurring due to contact between the cooling plate 722 and the light-transmitting element 500.

[0109] In this embodiment, the light-transmitting element 500 can focus the first laser passing through the first light-transmitting hole 210, and / or the light-transmitting element 500 can focus the second laser passing through the second light-transmitting hole 220, so as to adjust the focus and energy density of the first and second lasers.

[0110] The light-transmitting element 500 can be honeycomb glass, optical glass, optical crystal, polymethyl methacrylate (PMMA), or transparent ceramic.

[0111] In some embodiments of this application, the light-transmitting element 500 is provided with a plurality of through holes along the second direction Y to form a honeycomb light-transmitting structure.

[0112] In this embodiment, the light-transmitting element 500 is a honeycomb glass to adjust the focus of the first and second lasers. It should be noted that when the first and second lasers pass through the honeycomb glass, the honeycomb structure of the glass causes the light to undergo multiple reflections and refractions as it passes through, resulting in beam scattering. The scattered beam becomes more uniform, that is, it homogenizes the non-uniform beam (such as a Gaussian beam), thereby changing the focusing characteristics of the light.

[0113] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0114] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0115] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
