[0019] Compared with the prior art, the portable hair removal device of the present invention has the following advantages:

[0020] 1. In the field of portable hair removal devices, installing a light-transmitting crystal in the contact part allows the light-transmitting crystal, when in contact with the skin, to cool the skin, acting as a cold compress, reducing the burning sensation caused by the exposure of the light emitted by the light-emitting part to the skin.

[0021] 2. After installing the air supply element, heat dissipation path and heat dissipation assembly, the heat dissipation assembly is located between the air supply element and the heat dissipation path or on the side of the heat dissipation path that is adjacent to the air supply element, which improves the efficiency of the heat dissipation assembly in the removal mechanism hair. This also improves the efficiency of space utilization in the housing, while at the same time ensuring efficient heat dissipation, the volume of the portable hair removal device is also reduced.

[0022] 3. After installing the heat sink element and the heat conductive element, the heat sink element is installed in the first air outlet of the air supply element; Since the air pressure in the air outlet of the air supply element is higher, the heat dissipation efficiency of the heat sink element is increased, thus the heat conduction element increases the heat dissipation efficiency of the hair removal mechanism, reducing the burning sensation caused by hair removal and improving the user experience of the product.

[0023] 4. By increasing the number of second air outlets, the air removal efficiency of the heat dissipation path is improved and the space efficiency of the housing is further improved.

[0024] 5. Installing a seal to seal the gap between the heat dissipation channel and the air supply element prevents air from leaking from the air supply element, further improving the heat dissipation efficiency of the heat dissipation mechanism.

[0025] 6. After connecting one end of the heat conduction element to one side of the heat sink element, which is adjacent to the side of the light transmission crystal, the opposite end of the heat conduction element is connected to the heat sink element, that is, the heat conduction element is located on the side of the light transmission crystal and away from the direction of light emission, so that the light-transmitting crystal can protrude from the body, which makes it possible to reduce the size of the contact part, increasing the ratio of the area of the light-transmitting crystal on the surface of the side where the contact part comes into contact with the skin, so that thanks to the smaller size of the contact part, it is convenient for the user to observe the result in real time during the hair removal process time, there is no need to remove the device to check the result, this eliminates the problem associated with the fact that the large size of the contact part does not allow observation of the process and creates inconvenience for the process and observation; thus, the user experience is improved.

[0026] 7. By installing at least two heat-conducting elements on opposite sides of the heat-sink element, the heat-sink element causes the heat-sink element to more evenly dissipate the heat of the heat-conducting element and improves the heat dissipation efficiency.

[0027] 8. By installing a hollow insulating element between the filter of the light-emitting part and the light-transmitting crystal, the insulating element seals the area between the light-transmitting crystal and the light-emitting part, preventing air from liquefying on opposite sides of the filter and/or light-transmitting crystal, which further improves light emission and simultaneously prevents liquid leakage, protecting internal electronic components.

[0028] 9. After installing the semiconductor cooling plate directly between the heat conduction element and the light transmission crystal, the semiconductor cooling plate touches the light transmission crystal and dissipates heat, which further improves the heat dissipation efficiency of the light transmission crystal. Here, the semiconductor cooling plate is in contact with the side of the light transmission crystal in the wide side direction or the long side direction, so that the size of the contact part in the width direction is maintained, and when adding the semiconductor cooling plate, the width of the contact part is reduced, making the contact part suitable for hair removal on narrower areas. areas of the skin.

[0029] 10. After installing the first inductive element to detect the conductor, the hair removal device begins to emit light only after it actually comes into contact with the surface of the skin, preventing unnecessary radiation without contact with the skin, thus saving energy while increasing safe to use and prevent damage to external objects caused by unnecessary radiation.

[0030] 11. After installing the limiter, at least one side of the limiter and/or contact element next to the light transmitting crystal has a limiting part protruding towards the light transmitting crystal, in place of the light transmitting crystal opposite the limiting part there is a groove corresponding to the limiting part. The limiting part can be inserted into the groove, resting and being held therein, fixing the position of the light transmitting crystal and preventing it from accidentally falling out.

[0031] 12. As a result of dividing the first inductive element into at least two inductive portions, the at least two inductive portions are fixed in the ring so that light from the light-emitting portion is supplied by the switch only after the user's skin on which hair is to be removed , will be detected by each inductive section, so that during the hair removal process, only after the window of the hair removal device is in full contact with the skin, the plurality of inductive sections are electrically turned on; This prevents unnecessary light emission due to the user accidentally touching the top portion of the ring, further saving energy and improving safety of use. In addition, a plurality of inductive sections are electrically turned on at the same time when in contact with the skin, the skin with hair being removed completely covers the light transmission crystal, causing the light transmitted through the light transmission crystal to completely enter the skin to be cleaned, thereby preventing unnecessary light emission due to accidental contact by the user upper portion of the ring, preventing harm to the user caused by exposed radiation passing through the light transmitting crystal, which improves the safety of use in hair removal. Moreover, after forming a ring outside at least two inductive sections, the ring covers at least two inductive sections, hermetically closing the plurality of inductive sections and preventing the formation of liquid on the surface of the inductive section due to temperature changes, which leads to erroneous switching on of the first inductive element, which increases user safety during hair removal. By setting the distance between each of the inductive portions and the side of the ring away from the light-emitting portion to 0.2 to 2 mm when the ring touches the skin portion to be cleaned, in the detection region between the inductive portion and the skin to be cleaned, the detection sensitivity of the inductive portion is increased. By setting the distance between two adjacent inductive portions to be 3-30 mm, the distance between them is no longer too small where a user accidentally touching the portion between two adjacent inductive portions may trigger current, which further improves user safety during hair removal.

[0032] 13. After installing the nozzle, it has a detachable connection with the contact part, the hole in the nozzle and the light hole have different diameters, so that the user can install the nozzle needed to remove hair on a specific area of skin, especially small areas such as lips , fingers, etc.

[0033] 14. After installing the second inductive element in the hair removal head, the radiation can be controlled by detecting the conductor by the second inductive element.

[0034] 15. After installing the first magnetic element in the nozzle and adding the Hall effect switch, when the nozzle is connected to the hair removal mechanism, the Hall effect switch detects the short circuit of the first magnetic element, preventing the current caused by the detection of the first inductive element after installing the nozzle; The Hall effect switch can detect the connection of the nozzle and control the emission of the light emitting part.

Specific implementation options

[0068] In order to make the purpose, technical solution and advantages of the present invention more clear, the following is a detailed description of the invention, accompanied by drawings and embodiments. It should be understood that the specific embodiments described herein are used only to explain the present invention and do not limit it.

[0069] In FIG. 1 and fig. 2, the present invention provides a portable hair removal apparatus 1, which includes a housing 11, a heat dissipation mechanism 12, and a hair removal mechanism 13; the housing 11 defines a housing space in which the heat dissipation mechanism 12 and the hair removal mechanism 13 are housed; The hair removal mechanism 13 is used to remove hair on the skin by radiation in contact with the skin, and the heat dissipation mechanism 12 is used to dissipate the heat of the skin removal mechanism 13.

[0070] In FIG. 1 and fig. 2, in particular, the heat dissipation mechanism 12 includes an air supply element 121, a heat dissipation channel 122, and a heat dissipation assembly 123; a heat sink assembly 123 is located between the air supply element 121 and the heat dissipation path 122, or a heat sink assembly 1231 is located on the side of the heat dissipation path 122 adjacent to the air supply element 121.

[0071] On the housing 11, there is a first ventilation hole 111 and at least one second ventilation hole 112 in communication with the accommodating space; an air supply member 121 is positioned opposite the first vent 111, one end of a heat dissipation path 122 communicates with a second vent 112, and an air supply member 121 promotes air flow between the first vent 111 and the second vent 112.

[0072] It is understood that at least one second ventilation opening 112 may be on at least one side of the housing 11 in a vertical and/or horizontal direction to improve ventilation efficiency. For example, in the present embodiment, as an example for illustration, the number of the second ventilation holes 112 is 1, and the second ventilation holes 112 are located on one side of the housing 11 (shown in FIG. 1) in the vertical direction.

[0073] In FIG. 3 and fig. 4, heat sink assembly 123 includes a heat sink element 1231 and at least one heat conductive element 1232; the heat sink element 1231 is located between the air supply element 121 and the heat dissipation path 122, or the heat sink assembly 1231 may be on the side of the heat dissipation path 122 adjacent to the air supply element 121, one end of the heat dissipation path 122 communicates with the second vent 112, and the opposite end of the heat dissipation path 122 communicates with heat sink element 1231; one end of the heat conductive member 1232 contacts the heat sink member 1231, and the opposite end contacts at least one side of the hair removal mechanism 13 to dissipate heat thereto. Specifically, the heat conduction member 1232 includes an opposing condensation portion 12321 and a heat sink portion 12322, the condensation portion 12321 is in contact with the heat sink member 1231, and the heat sink portion 12322 is in contact with the hair removal mechanism 13.

[0074] It is understood that the heat conduction element 1232 is a heat pipe through which heat from the hair removal mechanism 13 is conducted. Of course, the heat conduction element 1232 also be a copper plate, an evaporation plate and other heat conductive material, but in any case, the heat conduction element 1232 must conduct the heat of the hair removal mechanism is 13, and there is no limit to this. For example, in the present embodiment, the thermal conductive element 1232 is a heat pipe, but this does not limit the present invention.

[0075] It is understood that the number of thermal conductive elements 1232 may be 1, 2, or more, and they can be added or removed as needed; for example, in the present embodiment, the number of thermal conductive elements 1232 is two, and each of the thermal conductive elements 1232 contacts a side of the skin removal mechanism 13 to conduct away heat.

[0076] In FIG. 3 and fig. 4, alternatively, heat sink element 1231 includes at least one connection plate 12311 and at least one heat sink element 12312; the heat sink element 12312 contacts one side of the connection plate 12311, and the heat conductive element 1232 contacts the other side of the connection plate 12311. For example, in the present embodiment, the number of heat sink elements 12312 may be 20, which are arranged in series, and each of the heat sink elements 12312 is located perpendicular to the connection plate plate 12311. There is a gap between two adjacent cooling plates 12312, so that air exhausted by the air supply element 121 can enter the heat sink element 1231 through the gap to remove heat. In addition, the heat sink element 1231 contacts the heat conduction element 1232 to remove heat from it, that is, the heat conduction element 1232 conducts heat removal of the hair removal mechanism 13.

[0077] It is understood that the heat sink member 1231 may be formed by welding a plurality of cooling plates 12312 to a connecting plate 12311; Compared with the traditional solid cooling plate, in the heat sink element 1231, the cooling plate 12312 can be thinner, so that with the same size, the heat sink element 1231 can have more cooling plates 12312, which increases the surface area of the heat sink element 1231 and improves heat dissipation efficiency. Of course, the heat sink element 1231 can also be directly used as a cooling plate, there is no limitation.

[0078] It is understood that the connection plate 12311 and the cooling plate 12312 can be made of copper, iron, aluminum and other one or more metallic heat-conducting materials, which can be selected as needed, and will not be mentioned further here.

[0079] In FIG. 1 and fig. 4, the air supply member 121 includes a first air intake hole 1211 and a first air outlet 1212; the first air inlet 1211 is opposite the first vent 111, and the first air outlet 1212 is oppositely connected to the heat sink member 1231.

[0080] The heat dissipation path 122 includes a second air inlet 1221 and at least one second air outlet 1222, the second air inlet 1221 is connected to the heat sink member 1231, and the second air outlet 1222 is in communication with the second vent 112.

[0081] In FIG. 1, fig. 4 and fig. 5, the air flow in the heat sink mechanism 12 moves as follows: when the air supply element 121 is open, it draws air from outside through the first air intake hole 1211 (in the direction "a" in FIG. 5), the air flows through the first air outlet 1212 outward into the heat sink element 1231, thus, the air flow from outside dissipates the heat of the heat sink element 1231, at the same time, the outside air passing through the heat sink element 1231 passes through the second air intake hole 1221 and enters the heat dissipation path 122 (direction "b" in FIG. 5), after which exits through the second air outlet 1222 (direction "c" in FIG. 5), that is, passes through the second air outlet 1222 and exits the second air outlet 112 outside the housing 11, allowing air to move between the first air outlet 111 and the second air vent 112.

[0082] It is understood that the air supply element 121 may be a blower that draws air from outside into the air supply element 121 from the first air intake hole 1211 and discharges it from the first air outlet 1212; From the characteristics of the blower, it can be seen that the air pressure at the first air outlet 1212 is greater than the air pressure at the first air inlet 1211, resulting in the air speed at the first air outlet 1212 being greater than that at the first air inlet 1211, further improving the dispersion efficiency heat by heat sink element 1231.

[0083] Alternatively, in FIG. 4 and fig. 6, heat sink mechanism 12 also includes a seal 124 that fits on one side of heat sink element 1231 adjacent to heat conduction element 1232, sealing the gap between heat sink element 122 and heat sink element 1231.

[0084] In particular, the seal 124 has a hollow structure and can be placed on the side of the heat sink element 1231 adjacent to the outside of the heat conductive element 1232, at least so that the seal 124 and the heat transfer channel 122 adjacent to the heat conductive element 1232 are flush with one sides, sealing the gap between the heat transfer channel 122 and the heat sink element 1231.

[0085] It is understood that the heat sink element 1231 is located on the side of the heat sink element 122 adjacent to the air supply element 121, so that a gap appears between the heat sink element 122 and the heat sink element 1231, and when air passes through the heat sink element 1231, it can exit through this gap , reducing the air flow entering the heat dissipation channel 122, reducing the heat removal efficiency of the hair removal mechanism 13. The seal 124 is added to seal the gap, preventing air leakage and increasing the heat removal efficiency of the hair removal mechanism 13.

[0086] Alternatively, as shown in FIG. 6, at a distance from the first air inlet 1211 there is a printed circuit board 18, opposite which there is an air supply element 121, where there is a control module (not shown in the figure), and the air flow generated by the air supply element 121 removes heat from the control module.

[0087] Alternatively, in FIG. 1 and fig. 7, the number of the second air outlets 1222 is two, and these two second air outlets 1222 are on the side of the housing 11 away from the hair removal mechanism 13. It is understood that the two second air outlets 1222 corresponding to the heat dissipation path 122 are located on both sides of the heat sink member 1231 and the air supply member 121, the air exits from the housing 11 on the side away from the hair removal mechanism 13. By adding additional second air outlets 1222, the air discharge efficiency of the heat dissipation path 122 is improved, further improving the efficiency of space utilization in the housing 11.

[0088] Alternatively, in FIG. 1 and fig. 8, the number of the second air outlets 1222 is two, and these two second air outlets 1222 are located on both sides of the housing 11. Of course, the two second air outlets 1222 may also be located in other places of the housing 11, this will not be mentioned further here.

[0089] As shown in FIG. 9 and fig. 10, the hair removal mechanism 13 includes a light emitting portion 131 and a contact portion 132, the light emitting portion 131 is used to emit light to a skin portion to be dehaired, and the contact portion 132 is used to contact the skin to be dehaired.

[0090] Specifically, the contact part 132 includes a light transmitting crystal 1321, which is in the light emitting direction of the light emitting part 131, the light transmitting crystal 1321 contacts the skin and cools it, acting as a cold compress, reducing the burning sensation on the skin caused by the light emitting part 131. The light transmitting crystal 1321 may be, but is not limited to, any of the following: sapphire crystal, quartz glass, and regular K9 glass.

[0091] It is understood that the condensation portion 12321 in the thermal conductive element 1232 contacts the heat sink element 1231, and the heat sink portion 12322 contacts at least one side of the light transmitting crystal 1321, so that the thermal conductive element 1232 can directly dissipate heat of the light transmitting crystal 1321.

[0092] Alternatively, the contact portion 132 also includes a ring 1322 and a contact element 1323, the contact element 1323 is applied to the outside of the light transmission crystal 1321, the ring 1322 is applied to the outside of the contact element 1323, the contact element 1323 closes the gap between the ring 1322 and the light transmission crystal 1321.

[0093] In addition, the contact member 1323 is plastic but may also be metal, for example, if the contact member 1323 is metal, it can be used to conduct heat sinking of the light transmitting crystal 1321 while also contacting the skin to enhance the cooling effect of the skin.

[0094] It is understood that the contact member 1323 is flush with the skin contact side of the light transmission crystal 1321 or below the skin contact side of the light transmission crystal 1321, resulting in the light transmission crystal 1321 always being in contact with the skin.

[0095] As shown in FIG. 11, the contact portion 132 also includes a stopper 1325 that fits onto the outside of the light transmitting crystal 1321 to secure it and prevent it from falling out.

[0096] In particular, on at least one side of the stopper 1325 and/or contact element 1323 adjacent the light transmittance crystal 1321 there is a restriction portion 13251 protruding towards the light transmittance crystal 1321, and at the location of the light transmittance crystal 1321 opposite the restriction portion 13251 there is a groove 13211 , corresponding to the limiting part 13251. The limiting part 13251 may be located in the groove 13211, supported and held therein, fixing the position of the light transmitting crystal 1321 and preventing it from accidentally falling out.

[0097] Alternatively, there are four grooves 13211, and they are located symmetrically on opposite sides of the light transmitting crystal 1321 in the direction of the long side "x", accordingly, the limiting parts 13251 are also four, and they are located on the side of the groove 13211 opposite the limiter 1325.

[0098] It is understood that the groove 13211 may also be at least one through groove on the light transmission crystal 1321, and the limiting portion 13251 corresponds to the groove 13211. Or the groove 13211 may also be on the side of the light transmission crystal 1321 adjacent to the contact element 1323 on both sides in the wide side "y" direction, and the limiting portion 13251 is on the side of the contact element 1323 opposite the groove 13211. Of course, the groove 13211 and the limiting portion 13251 may also be in other places, but the limiting portion 13251 must be in the groove 13211 so that the limiting portion 13251 could rest against the groove 13211, fixing the light transmitting crystal 1321, and will not be mentioned further here.

[0099] As shown in FIG. 9 and fig. 10, the light emitting portion 131 includes a lamp 1311, a filter 1312, and a reflective member 1313; lamp 1311, filter 1312 and reflective element 1313 are located in heat transfer channel 122.

[00100] Specifically, on the side of the heat dissipation channel 122 near the contact portion 132, there is a light hole 1314 and a transmission hole 1315, the transmission hole 1315 communicates with the heat dissipation channel 122. A lamp 1311 is installed in the heat dissipation channel 122 and is used to emit light onto the hair to be removed. through the light hole, the filter 1312 is in the light emission direction of the lamp 1311, the reflective element 1313 is in the opposite direction to the light emission, so that the light emitted by the lamp 1311 is collected through the reflective element 1313 and exits from the light hole 1314, passes through the filter 1312 , forming a predetermined light beam, and finally exited from the side of the light transmitting crystal 1321. The preset light beam hits the skin to be dehaired and is used to remove hair.

[00101] The reflective element 1313 and the filter 1312 together form an air duct that communicates with the passage holes 1315 (that is, the passage holes 1315 are on opposite sides of the air duct), the lamp 1311 is placed in the air duct, outside air through the passage hole 1315 passes through the air duct the passage, that is, the air entering the heat dissipation passage 122, can pass through the passage hole 1315 into the air passage passage and dissipate the heat of the light emitting portion 131, reducing the heat to be emitted by the light emitting portion 131.

[00102] From FIG. 9 and fig. 10, it can be understood that the light transmitting crystal 1321 includes a long side and a wide side (long side "x" and wide side "y" in FIG. 9), the length of the long side "x" is greater than or equal to the length of the wide side "y", a heat sink portion 12322 contacts at least one side of the light transmission crystal 1321, for example, in the present embodiment, a heat sink portion 12322 contacts the light transmittance crystal 1321 on at least one side corresponding to the long side "x" and/or the wide side "y", so as to contact the heat conductive element 1232 with the light transmitting crystal 1321 to dissipate heat from the light transmitting crystal 1321, reducing the temperature when the light transmitting crystal 1321 comes into contact with the skin, reducing the burning sensation on the skin caused by hair removal.

[00103] It is understood that in the present embodiment, the heat sink portion 12322 of the thermal conductive element 1232 contacts at least one side of the light transmitting crystal 1321 corresponding to the wide side "y", for example, two heat sink portions 12322 of the two heat conductive elements 1232 are separately adjacent to the two sides. light transmitting crystal 1321 corresponding to the wide side "y". As a result, the contact portion 132 maintains its size in the wide side "y" direction, and by adding the heat conductive member 1232, the width of the contact portion 132 is reduced, making the contact portion 132 suitable for hair removal on narrower areas of the skin.

[00104] In FIG. 10 and fig. 12, optionally, the heat sink mechanism 12 also includes at least half of a semiconductor cold plate 125 that is disposed between the light transmitting chip 1321 and the thermal conductive element 1232. Specifically, the semiconductor cold plate 125 includes an opposing cooling surface 1251 and a heat sink surface 1252, a cooling surface 1251 contacts a side of the light transmitting crystal 1321, and a heat sink surface 1252 contacts a heat sink portion 12322. The semiconductor cooling plate 125 is located between the heat conduction element 1232 and the light transmittance crystal 1321, and directly removes heat from the light transmittance crystal 1321, more increasing dispersion efficiency heat of the light transmitting crystal 1321.

[00105] It is understood that the semiconductor cooling plate 125 contacts at least one side of the light transmitting chip 1321 opposite the wide side "y", for example, in the present embodiment, the number of semiconductor cooling plates 125 is two, the two semiconductor cooling plates 125 are separately contacting two sides of the light transmitting crystal 1321 corresponding to the wide "y" side. As a result, the contact portion 132 maintains its size in the wide side "y" direction, and by adding the semiconductor cooling plate 125, the width of the contact portion 132 is reduced, making the contact portion 132 suitable for hair removal on narrower areas of the skin. Of course, the two semiconductor cold plates 125 can also contact by being on either side of the light transmission crystal 1321 opposite the long side "x", but in any case, the semiconductor cold plate 125 must contact the light transmission crystal 1321 to dissipate heat.

[00106] In FIG. 10 and fig. 12, alternatively, semiconductor cold plate 125 includes a positive wire 1253 and a negative wire 1254; a positive wire 1253 and a negative wire 1254 are located at opposite ends of the semiconductor cold plate 125, a positive wire 1253 and a negative wire 1254 wrap around opposite sides of the light transmission crystal 1321. Specifically, two semiconductor cold plates 125 are located symmetrically at the center of opposite sides of the light transmission crystal 1321, so that a positive wire 1253 of the semiconductor cold plate 125 extends along the long side "x" of the light transmission chip 1321 and is electrically connected to a negative wire 1254 of the semiconductor cold plate 125 so that two semiconductor cold plates 125 are connected in series with a positive wire 1253 and a negative wire 1254 that wrap around the two sides. light transmitting crystal, increasing space efficiency and further reducing the size of the contact portion 132, which can be used to remove hair from narrower areas of the skin.

[00107] In FIG. 13, alternatively, a hollow insulating member 126 is positioned between the filter 1312 and the light transmission crystal 1321, sealing the area between the light transmission crystal 1321 and the filter 1312.

[00108] It is understood that the insulating element 126 has a projection 1261 at the edge of the cavity, and when the isolating element 126 is installed outside the light transmission crystal 1321, it fixes the side of the light transmission crystal 1321 adjacent to the filter 1312 on the projection 1261, so that between the filter 1312 and the light transmission crystal 1321 a vacuum is maintained at all times, that is, the insulating element 126 hermetically seals the area between the light transmission crystal 1321 and the filter 1312, preventing liquefaction of air on opposite sides of the filter 1312 and/or light transmission crystal 1321, further improving the quality of light emission, preventing liquid leakage and protecting internal electronic components.

[00109] In FIG. 14, the portable hair removal device 1 also includes a switch 14 and a power supply 15; switch 14 is used to turn lamp 1311 on and off, and power supply 15 is used to supply power to lamp 1311.

[00110] In FIG. 15, the contact portion 132 also includes a first inductive element 1324 (shown by a dotted line in FIG. 14) and a control module (not shown in the figure); a first inductive element 1324 is located in the ring 1322 and is used to detect a conductor.

[00111] It is understood that the first inductive element 1324 is an inductive metal plate (eg, copper or silver) used to detect a conductor by bringing the conductor (eg, skin being depilated) closer to the first inductive element 1324, and its capacitance changes. in accordance with the change in capacitance, a control signal is supplied to the control module to control the inclusion of lamp 1311.

[00112] Specifically, the first inductive element 1324 is electrically connected to the control module, the control module is electrically connected to the lamp 1311, when the first inductive element 1324 detects a conductor, it supplies current to the control module, the control module turns on the lamp 1311 and the power supply 15, then the user can control the operation of the lamp 1311 using the switch 14, that is, when the first inductive element 1324 detects a conductor (for example, skin being cleaned of hair), and when the user presses the switch 14, the lamp 1311 is turned on, which prevents the lamp 1311 from being unnecessarily turned on without contact with skin, saving electrical energy while increasing the safety of hair removal by preventing damage caused by unnecessary radiation to external objects.

[00113] In FIG. 16, alternatively, the first inductive element 1324 includes at least two inductive sections 13241 that are located in the ring 1322 and electrically coupled to the control module. For example, in the present embodiment, the number of inductive sections 13241 is two, and the two inductive sections 13241 are evenly distributed in the ring 1322. Of course, there can also be 3, 4 or more inductive sections 13241, there is no limitation.

[00114] It is understood that the first inductive element 1324 is represented by a plurality of inductive sections 13241, and after the user's hair-cleansed skin is detected immediately by each of the inductive sections 13241, the plurality of inductive sections 13241 and the control module are simultaneously turned on, the control module turns on the lamp tube 1311 and a power supply 15, then the user can control the operation of the tube lamp 1311 through the switch 14.

[00115] It is understood that by installing a plurality of inductive sections 13241, it is possible to ensure that during the hair removal process, current is passed only after the skin is simultaneously detected by a plurality of inductive sections 13241, this prevents unnecessary light emission due to the user accidentally touching the upper region of the ring, which Saves energy even more. In addition, when the user's skin is detected by a plurality of inductive portions 13241 at once, the skin with hair being removed completely covers the light transmission crystal 1321, causing the light transmitted through the light transmission crystal 1321 to completely fall on the skin to be cleaned, thereby preventing unnecessary light emission due to accidental touching. by the user of the upper portion of the ring, harm to the user caused by exposed radiation passing through the light transmitting crystal 1321 is prevented, which improves the safety of use in hair removal.

[00116] In FIG. 16 and fig. 17, alternatively, a ring 1322 is formed on the outside of the at least two inductive portions 13241, that is, a ring 1322 is molded on the outside of the at least two inductive portions 13241 such that the ring 1322 covers the at least two inductive portions 13241, sealing the multiple inductive sections 13241, preventing the formation of liquid on the surface of the inductive section 13241 due to temperature changes (the resulting liquid will cause the inductive section 13241 to operate) and the erroneous activation of the first inductive element 1324, which improves safety. user during hair removal.

[00117] The distance between each of the inductive portions 13241 and the side of the ring 1322 away from the light emitting portion 131 is 0.2-2 mm (distance "d1" in FIG. 17), and when the ring 1322 touches the area of skin being cleaned, in the area detection between the inductive portion 13241 and the skin being cleaned, the detection sensitivity of the inductive portion 13241 is increased.

[00118] Moreover, the distance between two adjacent inductive portions 13241 is 3-30 mm (distance "d2" in FIG. 16), it is no longer too small when a user accidentally touching the portion between two adjacent inductive portions 13241 may cause switching on the current, which further increases user safety during hair removal.

[00119] In FIG. 18 and fig. 19, the portable hair removal device 1 also includes an attachment 16 that is releasably coupled to a contact portion 132. Specifically, a first magnetic element 161 is provided within the attachment 16, and a second magnetic element 113 is provided within the housing 11 at a location opposite the contact element 1323 , the first magnetic element 161 is magnetically connected to the second magnetic element 113.

[00120] In particular, the nozzle 16 also has a nozzle hole 162 and a second inductive element 163, the nozzle hole 162 is located at the nozzle position opposite the light transmission crystal 1321, so that the light emitted by the light transmission crystal 1321 passes through the nozzle hole 162. The second inductive element 163 fits on the outside of the opening of the nozzle 162 and is used to locate the conductor. When the nozzle 16 is magnetically coupled to the contact portion 132, the first inductive element 1324 and the second inductive element 163 are electrically turned on, that is, the nozzle 16 detects the skin being cleaned through the second inductive element 163 and controls the operation of the light-emitting portion 131.

[00121] It is understood that the hole of the nozzle 162 and the light transmitting crystal 1321 have different diameters, which makes it possible to change the light emitting area of the portable hair removal device 1 so that the device is suitable for removing hair on different parts of the body, for example, in the present embodiment, the hole of the nozzle 162 Smaller than the diameter of the light transmitting crystal 1321, the attachment can be used to remove hair from small areas of the body. Moreover, the surface of the nozzle 16 has an inclined structure, that is, the nozzle 16 is located adjacent to the side of the contact portion 132, forming a “trapezoidal” structure on the opposite side, so that the nozzle 16 can penetrate deeply into relatively shallow areas of the body to remove hair, which improves the convenience of a portable device for hair removal 1 on a wide variety of areas of the body.

[00122] It is understood that a conversion filter (not shown in the figure) is provided at the location where the nozzle 16 has an opening 162, and the light emitted by the light transmitting crystal 1321 passes through this filter and exits the nozzle opening 162 at a predetermined power. For example, if the user needs to treat eyebrows, fingers and other parts of the body with the device, the light must pass through the conversion filter of the nozzle 16 and come out with the desired frequency range suitable for working with specific parts of the body.

[00123] Alternatively, the opening of the nozzle 162 may contain a light-transmitting element that contacts the skin, acting as a cold compress to cool it.

[00124] In FIG. 18 and fig. 20, the nozzle 16 has a metal surface 164 on one side adjacent to the light transmitting crystal 1321, this metal surface 164 may expose the nozzle 16 or be located within the nozzle 16; the metal surface 164 is connected to the second inductive element 163, particularly through a metal element (not shown in the figure), so that when the tip 16 is connected to the contact part 132, the first inductive element 1324 detects the metal surface 164 and, with the help of the metal element, conducts conduction a first inductive element 1324 and a second inductive element 163.

[00125] It is understood that the material of the metal surface 164 and the metal element may be, among other things, aluminum, iron, or copper, or a combination thereof.

[00126] In FIG. 19 and fig. 21 portable hair removal device 1 also includes a Hall effect switch 17, which is located on the side of the housing 11 adjacent to the contact portion 132 and 17 is electrically connected to the control module.

[00127] When the attachment 16 is magnetically connected to the contact portion 132, the Hall effect switch 17 detects the magnetic field of the first magnetic element 161 and is closed, and then controls the light emission of the portable hair removal device 1 after the attachment 16 is attached.

[00128] Specifically, when the attachment 16 is magnetically connected to the contact portion 132, the first inductive element 1324 detects the first magnetic element 161 and is turned on electrically, that is, after installing the attachment on the portable hair removal device 1 due to the activation of the first inductive element 1324 The portable hair remover 1 can directly control light emission through the switch 14. After installing the Hall effect switch 17, it reduces or nullifies the capacitance change value caused by the first magnetic element 161 for the first inductive element 1324, and prevents unnecessary light emission caused by erroneously turning on the first inductive element 1324 after attaching the nozzle.

[00129] Moreover, when the tip 16 is magnetically connected to the contact portion 132 and detects a conductor, the first inductive element 1324 and the second inductive element 163 are electrically turned on, that is, the first inductive element 1324 can, in accordance with the change in the capacitance of the second inductive element 163, transmit a signal into the control module, controlling the light emission through the control module.

[00130] In FIG. 22 and fig. 23, in one embodiment, one end of the thermal conductive element 1232 is connected to a side of the light conductive crystal 1321 adjacent to one end of the heat sink element 123, and the opposite end of the thermal conductive element 1232 is connected to the heat sink element 123. That is, the thermal conductive element 1232 is located on the side of the light conductive crystal 1321 and on side away from the irradiation direction so that the light transmission crystal 1321 can protrude from the body 11 (as shown in FIG. 23), the size of the contact portion 132 is reduced, increasing the area ratio of the light transmission crystal 1321 on the side where the contact portion 132 contacts the skin, so that when the user removes hair, the smaller size of the contact part 132 allows him to observe the result in real time without having to remove the device to check the result, this eliminates the inconvenience that the too large contact part 132 makes monitoring and operation difficult, thus , user experience is improved.

[00131] It is understood that the number of thermal conductive elements 1232 may be 1, 2, 3 or more, but one end of each thermal conductive element 1232 must be connected to the side of the light conductive crystal 1321 adjacent to one end of the heat sink element 123 to reduce the size of the contact portion 132, here no restrictions.

[00132] It is understood that the thermal conductive element 1232 is connected to the light transmitting crystal 1321, this may be either a direct contact connection between the thermal conductive element 1232 and the light transmitting crystal 1321, or an indirect connection between 1232 and the light transmitting crystal 1321, for example, the thermal conductive element 1232 may be connected to the light transmitting crystal 1321 through the semiconductor cooling plate 125, no further mention will be made here.

[00133] In one embodiment, the number of thermal conductive elements 1232 is two, the two thermal conductive elements 1232 are located on opposite sides of the heat sink element 1231, each of the thermal conductive elements 1232 is connected to the heat sink element 1231 and the light transmitting crystal 1321 on the same side, that is, a condensation portion 12321 of each of the heat conductive elements 1232 is located coplanar with the heat dissipation portion 12322, and one of the heat conductive elements 1232 is located on one side of the heat sink element 1231, and the other heat conductive element 1232 is located on the opposite side of the heat sink element 1231, the heat conductive elements 1232 are located on opposite sides heat sink element 1231, such that the heat sink element 1231 dissipates heat of the heat conductive element 1231 more evenly, improving heat sink efficiency.

[00134] Alternatively, in FIG. 22 and fig. 24, thermal conductive element 1232 may have either a U-shaped or similar shape (as shown in thermal conductive element 1232 in FIG. 22) or an L-shaped or similar shape (as shown in thermal conductive element 1232 in FIG. 24), but the thermal conductive elements 1232 should be on opposite sides of the heat sink element 1231. Of course, the number of heat conductive elements 1232 can be 1, 3, 4, 5 or more, but if there are more than one, they are installed on opposite ends of the heat sink element 1231, there is no limitation. For example, if the number of thermal conductive elements 1232 is one, one thermal conductive element 1232 is installed on one side of the heat sink element 1231.

[00135] As shown in FIG. 25, in another embodiment, when the heat conduction element 1232 is an evaporation plate, one end of the two heat conduction elements 1232 covers opposite sides of the heat sink element 1231, one end is connected to the light transmitting crystal 1321, improving the heat dissipation efficiency. Of course, the number of evaporator plates can also be 1, in which case one evaporator plate is installed on one side of the heat sink element 1231.

[00136] The foregoing describes only the best embodiment of the present invention and is not intended to limit it. Any modifications, equivalent substitutions and improvements made within the principles of the invention are within the scope of protection of this invention.
