Description

Technical Field

[0001] The present application relates to the technical field of beauty equipment, and in particular to a beauty instrument and a self-cleaning method of the beauty instrument. Background Art

[0002] With the improvement of living standards and consumers' increasing attention to personal image, skin care has become a daily need for the public. Beauty devices can improve skin conditions through temperature changes to meet different beauty needs. Currently, beauty devices usually have two modes: ice compress and hot compress. The ice compress mode uses low temperature to shrink pores, reduce skin redness and inflammation, promote blood circulation, help soothe and tighten the skin, and is suitable for eye care, dark circles and swelling. The hot compress mode can promote blood circulation through warm temperature, open pores, and help the skin better absorb skin care products. It is suitable for facial massage, promoting collagen production and improving skin elasticity.

[0003] Among them, when users use beauty instruments, they usually use them together with beauty serum. During the process of applying hot and cold compresses to the skin, the care head of the beauty instrument needs to directly contact the beauty serum on the skin surface, which results in some beauty serum remaining on the care head after the user completes the skin care.

[0004] Therefore, after using the beauty instrument, users need to wipe or clean the care head with a tissue or other means, but the cleaning liquid may remain in the gaps on the care head and other places that are difficult to clean. The residual cleaning liquid is easy to breed bacteria. When the user uses the beauty instrument again, the bred bacteria may cause certain damage to the human skin and affect the skin care effect. Summary of the invention

In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0049] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense.

[0052] See also Figure 1 , Figure 2 and Figure 3 The beauty instrument provided by an embodiment of the present application includes a care head 100 and an energy source 200. The care head 100 has a care surface 110, and the care surface 110 is used to contact the skin. The energy source 200 is arranged inside the care head 100, and can output cold or heat in a controlled manner to reduce or increase the surface temperature of the care surface 110 on the care head 100, thereby achieving the effect of cold or hot compress on the skin.

[0053] Specifically, when the energy source 200 outputs cold energy, the surface temperature of the care surface 110 will decrease, and the care surface 110 can have a cold compress effect when it contacts the skin, thereby shrinking pores through low temperature, reducing skin redness and inflammation, promoting blood circulation, and helping to soothe and tighten the skin. It is suitable for eye care, removing dark circles and reducing swelling.

[0054] When the energy source 200 outputs heat, the surface temperature of the care surface 110 will increase. The care surface 110 can have the effect of hot compress when it contacts the skin. The warm temperature can promote blood circulation, open pores, and help the skin better absorb skin care products. It is suitable for facial massage, promoting collagen production and improving skin elasticity.

[0055] When the user uses beauty liquid with the beauty instrument for skin care, even after wiping the care surface 110, the beauty liquid will remain in the gaps of the care surface 110. In order to prevent the residual beauty liquid from breeding bacteria, the energy source 200 can be controlled to continuously output cold energy so that the air precipitates condensed water on the care surface 110. When the condensed water flows on the care surface 110, the beauty liquid in the gaps of the care surface 110 can be cleaned.

[0056] In order to prevent condensed water from dripping from the surface of the beauty instrument to the ground or the table to pollute the surrounding environment, the beauty instrument also includes a water collecting part 300. The water collecting part 300 is arranged at the bottom of the care head 100 and has an opening 310 connected to the interior of the care head. Water on the care surface 110 can fall into the water collecting part 300 through the opening 310.

[0057] In this way, the condensed water on the care surface 110 can flow into the water collecting part 300 through the opening 310, and the condensed water can clean the gaps on the care head 100 while flowing on the care surface 110, thereby preventing the beauty liquid and its own bacteria from remaining in the gaps of the care surface 110, and completing the self-cleaning of the beauty instrument. In addition, after the beauty instrument is self-cleaned, the sewage enters the water collecting part 300, making it convenient for the user to handle the sewage.

[0058] It should be noted that, in actual use, when the energy source 200 outputs less cold energy and the temperature of the care surface 110 is only slightly lower than the room temperature, the water vapor in the air will directly precipitate on the care surface 110 to form condensed water, but this process takes a long time. Therefore, the energy source 200 can output a large amount of cold energy in a short time, so that the temperature of the care surface 110 can be reduced to a large difference from the room temperature in a short time, so that the water vapor in the air can condense on the care surface 110, and then the energy source 200 outputs heat to melt the condensed water vapor, thereby forming melt water, and then the care surface 110 is cleaned by the melt water. For details, please refer to the self-cleaning method of the beauty instrument described below.

[0059] Regardless of whether it is melt water or condensed water, when the water flows through the care surface 110, it can clean the care surface 110 and small gaps, thereby achieving self-cleaning of the care head 100. In addition, the sewage generated by self-cleaning will directly enter the water collecting part 300, so that the user can centrally treat the sewage.

[0060] In some embodiments of the present application, refer to Figure 3The care head 100 includes a care shell 121 and a care electrode 122. The care shell 121 is formed with a care surface 110. The care electrode 122 is arranged in the care shell 121 and is located on the care surface 110. In actual use, the care electrode 122 can also emit a tiny current to stimulate the skin and muscles, promote blood circulation and lymphatic detoxification, and thus improve the metabolism and regeneration ability of the skin.

[0061] The care electrode 122 is connected to the energy source 200 in a heat transfer manner, so that the cold or heat generated by the energy source 200 can be input to the care electrode 122 to reduce or increase the surface temperature of the care surface 110. In this way, the care electrode 122 can provide a cold or hot compress effect on the skin while providing a slight current stimulation to the skin.

[0062] In some embodiments, the care head 100 includes two care electrodes 122, and two care surfaces 110 are arranged at intervals on the care housing 121, and each care surface 110 is provided with a care electrode 122. The two care electrodes 122 can be arranged in different shapes, and when the user uses the care electrodes 122 of different shapes, the care electrodes 122 of different shapes can bring different massage experiences to the user, and the user can select the required care electrodes 122 according to his or her own preferences.

[0063] It should be noted that, in order to collect the sewage on the two care surfaces 110, the water collecting member 300 may also include two, and the openings 310 of the two water collecting members 300 are respectively located at the bottom of the two care surfaces 110, so that the sewage on the two care surfaces 110 flows into the two water collecting members 300. In some other embodiments, the water collecting member 300 may also include one, but the opening 310 of the water collecting member 300 covers the bottom of the two care surfaces 110, so that the sewage on the two care surfaces 110 can flow into the water collecting member 300 through the opening 310.

[0064] Furthermore, the energy source 200 is a semiconductor cooling sheet 210. The semiconductor cooling sheet 210 uses the Peltier effect of semiconductor materials to generate a temperature difference between the two ends of the material through electric current, thereby achieving cooling. When the current passes through two different types of semiconductor materials, N-type and P-type, one end absorbs heat and the other end releases heat, achieving the effect of cooling and heating.

[0065] It should be noted that in some other embodiments, electromagnetic heating, liquid nitrogen cooling, or magnetic refrigeration may be used to output cold or heat. In some other embodiments, the semiconductor cooling sheet 210 may be directly in contact with the care shell 121 to increase or decrease the temperature of the care surface 110.

[0066] In some embodiments, see Figure 4 The semiconductor cooling plate 210 has a first heat exchange surface 211 and a second heat exchange surface 212 that are arranged opposite to each other. According to the cooling and heating principle of the semiconductor cooling plate 210, one of the first heat exchange surface 211 and the second heat exchange surface 212 can output cold as a cooling end, and the other can output heat as a heating end. When the direction of the current passing through the semiconductor cooling plate 210 is opposite, the cooling end and the heating end of the semiconductor cooling plate 210 are exchanged with each other, so that the first heat exchange surface 211 and the second heat exchange surface 212 can both output cold or heat.

[0067] Specifically, the first heat exchange surface 211 is heat-transferably connected to one of the care heads 100, so that the cold or heat output by the first heat exchange surface 211 can be transferred to the care head 100, and when the user needs to switch from cold compress to hot compress, or from hot compress to cold compress, the direction of the current passing through the semiconductor refrigeration sheet 210 can be changed, thereby changing the skin care mode of the beauty instrument.

[0068] The other care electrode 122 is heat-transferably connected to the second heat exchange surface 212, so that the cold or heat generated by the second heat exchange surface 212 can be input to the care electrode 122. When the user selects the care electrode 122 for skin care, the care electrode 122 can also perform cold or hot compress at the same time.

[0069] When the user needs a cold compress, the first heat exchange surface 211 outputs cold air, and the second heat exchange surface 212 outputs heat. If the heat of the second heat exchange surface 212 accumulates inside the beauty instrument, the temperature of the electronic components inside the beauty instrument will be too high, affecting the normal operation of the beauty instrument.

[0070] By heat-transfer connecting the second heat exchange surface 212 with another care electrode 122, the heat generated by the second heat exchange surface 212 can be transferred to the outside through the care electrode 122, thereby preventing heat from accumulating inside the beauty instrument and causing damage to the device. Conversely, when the second heat exchange surface 212 outputs cold energy, the heat output by the first heat exchange surface 211 can also be dissipated to the outside through the corresponding heat-transfer connected care electrode 122, thereby preventing heat from accumulating inside the beauty instrument.

[0071] Specifically in some embodiments, the two care surfaces 110 are respectively arranged at opposite ends of the care housing 121 so that the two care electrodes 122 do not interfere with each other. The semiconductor refrigeration element is usually arranged close to one of the care electrodes 122 and farther from the other care electrode 122. For this purpose, the beauty instrument further includes a heat conductor 320, one end of the heat conductor 320 is heat-conductingly connected to the second heat exchange surface 212, and the other end is heat-conductingly connected to the corresponding care electrode 122 of the second heat exchange surface 212, so that the heat or cold of the semiconductor refrigeration element is transferred to the other care electrode 122 through the heat conductor 320.

[0072] In some embodiments, it can be seen from the cleaning process of the above-mentioned beauty instrument that when the temperature of the care surface 110 drops to a large difference from the room temperature in a short time, the water vapor in the air can condense on the care surface 110. At this time, the energy source 200 needs to output heat to melt the condensed water vapor and form melt water. When the semiconductor refrigeration sheet 210 is cooling, the lowest temperature generated can reach -45°, and the water vapor in the air will directly condense on the care surface 110. Therefore, the semiconductor refrigeration sheet 210 needs to be heated during self-cleaning to achieve the effect of quickly melting ice to produce clean water.

[0073] The semiconductor refrigeration sheet 210 also generates heat when cooling, and heat is needed to melt ice later. For this reason, the heat generated by the semiconductor refrigeration sheet 210 during cooling can be collected for melting ice. For this reason, in some embodiments, the beauty instrument further includes a heat storage element 330, which is disposed in the care head 100 and is heat-conductingly connected to the second heat exchange surface 212.

[0074] Thus, when the first heat exchange surface 211 of the semiconductor refrigeration sheet 210 cools to condense water vapor in the air on the care surface 110, the heat generated by the second heat exchange surface 212 is transferred to the heat storage element 330 and temporarily stored in the heat storage element 330. When the semiconductor refrigeration sheet 210 stops cooling after a period of time, the heat stored in the heat storage element 330 is transferred to the care electrode 122 through the semiconductor refrigeration sheet 210, thereby heating the condensed water vapor on the care surface 110, so that the condensed water vapor melts to clean the care head 100.

[0075] By providing the heat storage component 330, when the beauty instrument is self-cleaning, the semiconductor refrigeration plate 210 does not need to be used for heating after cooling. The heat stored in the heat storage component 330 can directly melt the condensed water vapor, thereby achieving the effect of saving energy consumption.

[0076] It should be noted that the heat sink and the heat storage element 330 can be set either alone or at the same time. When the heat sink and the heat storage element 330 are set at the same time, part of the heat generated by the second heat exchange surface 212 is dissipated through the heat sink and the corresponding nursing electrode 122 connected to the heat sink, and the other part is stored in the heat storage element 330 for subsequent melting of condensed water vapor.

[0077] In some embodiments, the energy source 200 includes two semiconductor refrigeration sheets 210, the two semiconductor refrigeration sheets 210 are arranged at intervals, the first heat exchange surfaces 211 of the two semiconductor refrigeration sheets 210 are respectively connected to the two nursing electrodes 122 for heat transfer, and the second heat exchange surfaces 212 of the two semiconductor refrigeration sheets 210 are connected to each other for heat transfer. In this way, each nursing electrode 122 can output cold and heat separately through a separate semiconductor refrigeration sheet 210, without the need to transfer heat through the heat conductor 320, thereby reducing energy loss, improving energy utilization, and achieving a rapid cooling effect.

[0078] Specifically, the two care electrodes 122 are spaced apart at opposite ends of the care housing 121 along a first direction. When the beauty instrument is in use, the first direction is perpendicular to the neutral direction, that is, Figure 3 The two semiconductor cooling sheets 210 are also spaced apart along the first direction, and a heat conductor 320 is disposed between the two semiconductor cooling sheets 210. The two semiconductor cooling sheets 210 are respectively connected to the nursing electrodes 122 closest to them for heat transfer. When the user uses any of the nursing electrodes 122 for cold compress, the heat or cold can be output through the semiconductor cooling sheet 210 closest to the nursing electrode 122. The cold output by the semiconductor cooling sheet 210 directly enters the nursing electrode 122 without passing through the heat conductor 320, thereby reducing heat loss and improving energy utilization.

[0079] It is understandable that a heat storage component 330 may also be provided between the two semiconductor refrigeration plates 210, so that when the two care electrodes 122 are self-cleaning, the heat output by the two semiconductor refrigeration plates 210 can be temporarily stored in the heat storage component 330, and subsequently used to melt the water vapor condensed around the care electrodes 122.

[0080] Furthermore, when the beauty instrument is self-cleaning, heat can be output to the corresponding care surface 110 through the first heat exchange surface 211 of one of the semiconductor refrigeration plates 210, and the first heat exchange surface 211 of the other semiconductor refrigeration plate 210 can output cold to the corresponding care surface 110. The heat and cold output by the second heat exchange surfaces 212 of the two semiconductor refrigeration plates 210 just offset each other, thereby enabling the two care surfaces 110 to self-clean at the same time.

[0081] In some embodiments, the beauty instrument also includes a body 400, a control module 410 and a battery module 420. The care head 100 is disposed on the body 400, the control module 410 is disposed in the body 400, and the control module 410 is electrically connected to the semiconductor refrigeration chip 210 and the battery module 420 respectively. The control module 410 can controllably switch the direction of the current passing through the semiconductor refrigeration chip 210, thereby switching the cooling end and the heating end in the semiconductor refrigeration chip 210.

[0082] Furthermore, the beauty instrument further includes a charging base 430, on which the body 400 is detachably arranged, and when the body 400 is located on the charging base 430, the battery module 420 is electrically connected to the charging base 430, so as to charge the battery module 420 through the charging base 430. When the body 400 is located on the charging base 430, the opening 310 is located below the care electrode 122 in the direction of gravity, so that the beauty instrument can start the self-cleaning mode of the beauty instrument when charging, thereby cleaning the care surface 110, and the cleaned sewage will fall into the water collecting part 300.

[0083] In some embodiments of the present application, refer to Figure 1 The electrodes of the care head 100 include a plurality of electrode blocks 123, all of which are protruding from the outer surface of the care housing 121. Thus, when the user uses the side of the care head 100 with the plurality of electrode blocks 123 for skin care, the plurality of electrode blocks 123 can form a massage effect on the skin, thereby accelerating the absorption of the beauty serum.

[0084] In order to allow the clean water formed by the care surface 110 to smoothly enter the water collecting member 300, all the electrode blocks 123 are surrounded to form a water flow channel 140 and a flow channel outlet 141 connected to the water flow channel 140, and the flow channel outlet 141 can be connected to the opening 310 on the water collecting member 300. The flow channel outlet 141 is located at the bottom of the care head 100 and is located in the opening 310 of the water collecting member 300, so that the water in the water flow channel 140 can enter the opening 310 of the water collecting member 300 through the flow channel outlet 141, and finally stored in the water collecting member 300.

[0085] During the self-cleaning process of the beauty instrument, whether it is condensed water precipitated on the care surface 110 or melted water formed by melting condensed water vapor, the water on the care surface 110 will flow on the surface of the electrode block 123, which will drive the stains on the surface of the electrode block 123 to flow into the water flow channel 140, thereby cleaning the surface of the electrode block 123 and the care shell 121. The sewage entering the water flow channel 140 will continue to move along the water flow channel 140 under the action of gravity until it flows out from the flow channel outlet 141 at the bottom of the care head 100, and finally enters the water collection part 300 for temporary storage so that the user can centrally process it.

[0086] In some other embodiments, see Figure 5 , and the outer surface of the care electrode 122 can be made flush with the care surface 110, so that the outer surface of the care head 100 is a smooth surface. Therefore, the condensed water or melted water on the outer surface of the care head 100 can flow along the surface of the care surface 110 and the surface of the care electrode 122, and finally flow into the water collection port at the bottom of the care head 100.

[0087] Specifically in one embodiment, among the two care surfaces 110 on the care head 100, the care electrode 122 of one includes multiple electrode blocks 123, and the surface of the other care electrode 122 is flush with the care surface 110. The user can choose any care surface 110 to perform skin care according to usage requirements.

[0088] When the beauty device is performing self-cleaning, at least one care surface 110 intersects both the horizontal plane and the plumb plane, and the plumb plane refers to a plane intersecting the horizontal plane. In other words, at least one care surface 110 is arranged at an angle, and in actual use, the care surface 110 faces upward in the direction of gravity, so that when the beauty device is performing self-cleaning, the cleaning water formed on the care surface 110 is not easy to fall off from the care surface 110, thereby increasing the residence time of the cleaning water on the care surface 110 and improving the cleaning effect of the care surface 110.

[0089] Specifically in one embodiment, refer to Figure 6 The angle formed by one care surface 110 and the plumb plane is α, α is 10°, and the angle formed by the other care surface 110 and the plumb plane is β, β is 6°.

[0090] In some embodiments of the present application, refer to Figure 7 and Figure 8 The water collecting member 300 can be detachably arranged on the care head 100, so that after the water collecting member 300 collects the sewage from the cleaning care surface 110, the user can remove the water collecting member 300 from the care head 100 to clean the water collecting member 300.

[0091] In some embodiments, the care head 100 is provided with a slot 130, and the slot 130 is provided with an insertion port 150 at one end in the longitudinal direction thereof, and the water collecting member 300 is provided with an insertion portion 340, and the insertion portion 340 can be inserted into or removed from the slot 130 via the insertion port 150, thereby realizing the installation and removal of the water collecting member 300 on the care head 100. Specifically, the slot 130 includes two, and it can be understood that in some other examples, the slot 130 can also be provided on the water collecting member 300, and then the care head 100 is provided with an insertion portion 340.

[0092] The above beauty instrument has at least the following advantages:

[0093] After the user uses beauty liquid with the beauty instrument for skin care, even after wiping the care surface 110, the beauty liquid will remain in the gaps of the care surface 110. In order to prevent the residual beauty liquid from breeding bacteria, the energy source 200 can be controlled to continuously output cold energy so that the air precipitates condensed water on the care surface 110. During the process of the condensed water flowing on the care surface 110, the beauty liquid in the gaps of the care surface 110 can be cleaned.

[0094] In order to prevent condensed water from dripping from the surface of the beauty instrument to the ground or the table to pollute the surrounding environment, the beauty instrument also includes a water collecting part 300. The water collecting part 300 is arranged at the bottom of the care head 100 and has an opening 310 connected to the interior of the care head. Water on the care surface 110 can fall into the water collecting part 300 through the opening 310.

[0095] In this way, the condensed water on the care surface 110 can flow into the water collecting part 300 through the opening 310, and the condensed water can clean the gaps on the care head 100 while flowing on the care surface 110, thereby preventing the beauty liquid and its own bacteria from remaining in the gaps of the care surface 110, and completing the self-cleaning of the beauty instrument. In addition, after the beauty instrument is self-cleaned, the sewage enters the water collecting part 300, making it convenient for the user to handle the sewage.

[0096] The present application also provides a method for cleaning a beauty instrument, which is applied to the beauty instrument in any of the above embodiments, see Fig. 9 , in order to improve the cleaning speed of the beauty instrument, specifically including the following steps:

[0097] S1: Controlling the energy source 200 of the beauty instrument to output cooling capacity at maximum power for a first preset time;

[0098] S2: Control the energy source 200 to output heat for a second preset time

[0099] When the energy source 200 is a semiconductor refrigeration chip 210, when the semiconductor refrigeration chip 210 outputs cold energy at maximum power, the surface temperature of the semiconductor refrigeration chip 210 can be reduced to -45°, so that the surface temperature of the care surface 110 can be quickly reduced. The first preset time can be determined according to the area of ​​the care surface and the cooling power of the semiconductor refrigeration chip 210, until the water vapor in the air condenses into ice on the surface of the care surface 110 after the first preset time. After that, the semiconductor refrigeration chip 210 is controlled to output heat, and the second preset time can be determined according to the area of ​​the care surface and the heating power of the semiconductor refrigeration chip 210, until the second preset time, the heat will melt the ice on the surface of the care surface 110, and the melted water will flow on the surface of the care surface 110, which can have the effect of cleaning the care surface 110.

[0100] Furthermore, the cleaning method further includes step S3: looping steps S1-S2 N times, N≥2, that is, through step S3, the care surface 110 can be repeatedly cleaned to improve the cleaning efficiency. In addition, when the energy source 200 is a semiconductor cooling sheet 210, the switching between steps S1 and S2 can be achieved directly by switching the direction of the current passing through the semiconductor cooling sheet 210.

[0101] Through the above cleaning method, melt water can be formed on the surface of the care surface 110 in a short time, and the beauty liquid in the gap of the care surface 110 can be cleaned by the melt water, thereby achieving a quick cleaning effect, effectively avoiding the problem that the beauty liquid dries up and becomes difficult to clean during the cleaning process, and improving the cleaning efficiency.

[0102] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0103] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
