Description

Technical Field

[0001] The present application relates to the technical field of skin cleaning, and in particular to a skin cleaning device and a control method thereof. Background Art

[0002] Traditional methods of removing keratin, blackheads, acne and oily dirt from the surface and shallow layers of facial skin usually include the following methods. People may use other hard tools or squeeze them directly with their hands to remove blackheads, acne and excess oil; or use acne needles for professional acne cleaning. Another common practice is to apply blackhead removal liquid on the skin to soften and loosen keratin, blackheads, acne and oily dirt before cleaning. Another method is to directly stick a sticky sticker specially designed for removing keratin, blackheads, acne and oily dirt on the skin, tear off the sticker after it has been attached for a period of time, and use the sticky force of the sticky substance on the surface of the sticker to stick to the keratin, blackheads, acne and oily dirt on the skin surface.

[0003] However, there are many shortcomings in the above blackhead removal methods: First, the single-use nature of blackhead removal liquid and adhesive tape means that they need to be repurchased every time they are cleaned, which undoubtedly increases the financial burden on users. Moreover, since the blackhead removal liquid must be applied before using the adhesive tape, the entire cleaning process becomes cumbersome and time-consuming, which is particularly inconvenient in the fast-paced modern life. Secondly, although this method can temporarily remove keratin, blackheads, acne and grease dirt on the surface of the skin, it is helpless for deep skin problems. Deep blackheads and acne are still hidden under the skin and cannot be fundamentally solved by such surface treatment. This not only means that the problem may recur, but also in the long run, it may have an adverse effect on skin health. In addition, the use process may cause discomfort or even pain to the skin, especially for those users with more sensitive skin or more hair, this discomfort may be more obvious. Fixing the adhesive tape on the face for a long time, coupled with the blackhead removal liquid applied in the early stage, may cause irritation or damage to the skin, which is obviously a problem that cannot be ignored in today's pursuit of gentle skin care. The convenience of this blackhead removal method is also greatly reduced because it requires care at a specific time and place. It limits the possibility of users to perform skin care anytime and anywhere in their busy lives, making it more difficult to keep their skin clean and healthy. Finally, the chemical ingredients contained in blackhead removal liquids and stickers may cause adverse skin reactions for some users with sensitive skin. Without knowing the moisture content of their skin, users may inadvertently damage their skin in the process of removing blackheads, causing problems such as dry skin and itching. Moreover, this sticker does not provide users with a long-term solution and cannot meet users' needs for comprehensiveness and sustainability in the skin care process. Moreover, the efficiency of skin cleansing in traditional skin cleansing methods is very low.

[0004] Therefore, in the prior art, in order to improve the efficiency of smooth cleaning, skin cleaning equipment is born accordingly. Skin cleaning equipment is one of the equipment used for skin beauty care. The existing skin cleaning equipment can suck out blackheads, acne, grease dirt or keratin on the skin to achieve the effect of efficient skin cleaning. However, when cleaning blackheads, acne, grease dirt or keratin on the skin by suction, if the skin is not hydrated enough, it will cause damage to the skin. Therefore, the existing skin cleaning equipment is easy to damage the skin when cleaning the skin. Summary of the invention

[0005] Based on this, the purpose of this application is to overcome the shortcomings of the prior art and provide a skin cleaning device and a control method thereof, which can enhance the effect of water on skin impurities such as blackheads, acne, grease, dirt or keratin on the skin, thereby improving the cleaning effect.

[0022] By suctioning with a vacuum pump connected to the vacuum pump connector, the gas and / or water in the independent space is sucked to the vacuum pump connected to the vacuum pump connector via the second suction channel, the first suction channel and the vacuum pump connector, so as to suck the water after cleaning the skin.

[0038] See also Figure 1-5 , the first embodiment of the present application provides a skin cleaning device, comprising: a device body 1 and a water replenishing nozzle 2;

[0039] The device body 1 includes a suction nozzle connection mechanism 11, a vacuum pump connector 13 and a water replenishment connector 12, wherein the suction nozzle connection mechanism 11 is provided with a first suction channel and a first water delivery channel; the vacuum pump connector 13 is connected to the first suction channel, and the water replenishment connector 12 is connected to the first water delivery channel;

[0040] The water replenishment nozzle 2 includes a cleaning contact 21, a connecting head 23, and a second suction channel 25 and a second water delivery channel 27 arranged between the cleaning contact 21 and the connecting head 23; the connecting head 23 is used to connect with the nozzle connection mechanism 11, the suction port of the second suction channel 25 and the output port of the second water delivery channel 27 are located on the cleaning contact 21, and the cleaning contact 21 is provided with a contact protrusion 211, and the contact protrusion 211 surrounds the suction port of the second suction channel 25 and the output port of the second water delivery channel 27;

[0041] When the connector 23 of the water replenishment nozzle 2 is connected to the nozzle connection mechanism 11 of the device body 1 , the second suction channel 25 is connected to the first suction channel, and the second water delivery channel 27 is connected to the first water delivery channel.

[0042] The water replenishment connector is connected to the water supply source via one end of the device body 1; the vacuum pump connector 13 is connected to the sewage receiving bin, and the sewage receiving bin is used to receive sewage after cleaning the skin.

[0043] The skin cleaning device of the present invention outputs water to the cleaning contact 21 of the water replenishment nozzle 2 through the water replenishment connector 12, the first water delivery channel, and the second water delivery channel 27, and sucks the skin covered by the cleaning contact 21 through the vacuum pump connector 13, the first suction channel, and the second suction channel 25, so that the cleaning contact 21 can replenish water for the skin while sucking skin impurities such as blackheads, acne, grease, dirt, or keratin, so as to replenish moisture for the skin while cleaning the skin, and reduce the damage to the skin during cleaning. Moreover, by contacting the skin with the protruding portion 211 to surround an independent space isolated from the outside world, the output port of the second water delivery channel 27 and the suction port of the second suction channel 25 can be in an independent space, preventing the replenished water from flowing out of the outside world, and also preventing the outside world from affecting the suction effect, so as to achieve a better skin cleaning effect.

[0044] In a feasible embodiment, the device body 1 further includes a motor 15, a rotor of the motor 15 is connected to the nozzle connecting mechanism 11, and the motor 15 drives the nozzle connecting mechanism 11 to rotate, thereby driving the water replenishment nozzle 2 to rotate.

[0045] Specifically, when the motor 15 drives the nozzle connecting mechanism 11 to rotate, the outer wall of the convex hexagonal body of the nozzle connecting mechanism 11 abuts against the inner wall of the concave hexagonal groove of the water replenishment nozzle 2 to drive the water replenishment nozzle 2 to rotate, thereby increasing the fluidity of the water output by the two second water delivery channels 27 to better clean blackheads, acne, grease, dirt or keratin and other skin impurities on the skin.

[0046] In a feasible embodiment, the device body 1 further includes a fixing mechanism 17 , the housing of the motor 15 is connected to the fixing mechanism 17 , and the fixing mechanism 17 is used to fix the water replenishment connector 12 .

[0047] In a feasible embodiment, the second suction channel 25 is an annular channel, and the suction port of the second suction channel 25 is an annular suction port.

[0048] Among them, the annular channel and the annular suction port can disperse the pressure of the negative pressure, and can more completely suck out skin impurities and water such as blackheads, acne, grease, dirt or keratin, prevent the contact protrusion 211 from contacting the skin to obtain excessive water in the independent space and prevent the water from flowing out with blackheads, acne, grease, dirt or keratin and other skin impurities on the skin and re-polluting the skin.

[0049] In a feasible embodiment, the second suction channel 25 surrounds the second water delivery channel 27 , and the suction port of the second suction channel 25 surrounds the output port of the second water delivery channel 27 .

[0050] In this embodiment, the second suction channel 25 surrounds the second water supply channel 27, and the suction port of the second suction channel 25 surrounds the output port of the second water supply channel 27, which can improve the efficiency of sucking out the water output by the second water supply channel 27 and prevent the water from carrying skin impurities such as blackheads, acne, grease, dirt or keratin and flowing out onto the skin and re-polluting the skin.

[0051] In a feasible embodiment, the water replenishment nozzle 2 includes two second water delivery channels 27 , and the output ports of the second water delivery channels 27 are distributed on both sides of the center of the cleaning contact 21 .

[0052] In this embodiment, the output efficiency of water can be improved through the output ports of the two second water delivery channels 27 to ensure that sufficient moisture can be replenished for the skin.

[0053] In a feasible embodiment, the channel diameter of the second water transfer channel 27 decreases in a direction approaching the output port.

[0054] In this embodiment, since the channel diameter of the second water supply channel 27 decreases in the direction approaching the output port, when the water is output from the output port of the second water supply channel 27, the water pressure will be enhanced due to the compression of the water volume, thereby improving the output water strength to better clean blackheads, acne, grease, dirt or keratin and other skin impurities on the skin.

[0055] In a feasible embodiment, the nozzle connection mechanism 11 is provided with a first limiting portion 111 , the connection head 23 is provided with a second limiting portion 231 , and the connection head 23 is connected to the first limiting portion 111 of the nozzle connection mechanism 11 via the second limiting portion 231 .

[0056] In a feasible embodiment, the first limiting portion 111 of the nozzle connecting mechanism 11 is a convex limiting portion, and the second limiting portion 231 of the connecting head 23 is a concave limiting portion, and the concave limiting portion of the connecting head 23 is embedded and connected to the convex limiting portion of the nozzle connecting mechanism 11.

[0057] In a feasible embodiment, the convex limiting portion is a convex hexagonal body, and the concave limiting portion is a concave hexagonal groove.

[0058] Compared with the prior art, the skin cleaning device of the present invention outputs water to the cleaning contact 21 of the water replenishment nozzle 2 through the water replenishment connector 12, the first water delivery channel, and the second water delivery channel 27, and sucks the skin covered by the cleaning contact 21 through the vacuum pump connector 13, the first suction channel, and the second suction channel 25, so that the cleaning contact 21 can replenish water for the skin while sucking skin impurities such as blackheads, acne, grease, dirt, or keratin, so as to replenish moisture for the skin while cleaning the skin, and reduce the damage to the skin during cleaning. Moreover, by contacting the skin with the protruding portion 211 to surround an independent space isolated from the outside world, the output port of the second water delivery channel 27 and the suction port of the second suction channel 25 can be in an independent space, preventing the replenished water from flowing out of the outside world, and also preventing the outside world from affecting the suction effect, so as to achieve a better skin cleaning effect. At the same time, the present application is provided with two second water supply channels 27, and under the drive of the motor 15, the two second water supply channels 27 can rotate along with the water replenishment nozzle 2 to increase the fluidity of the water in the independent space, so as to enhance the effect of the water on blackheads, acne, grease dirt or keratin and other skin impurities on the skin, thereby improving the cleaning effect.

[0059] See also Figure 6 The second embodiment of the present application provides a skin cleaning device control method, which is applied to the skin cleaning device as described above, and the method includes:

[0060] S1: The cleaning contact is brought into contact with the skin so that the protruding part of the contact contacts the skin to form an independent space isolated from the outside world.

[0061] S2: Output water through a water replenisher connected to the water replenishment connector, so that the output water is output to the independent space via the water replenishment connector, the first water transfer channel and the second water transfer channel, so as to clean the skin covered by the contact protrusion with the output water.

[0062] S3: Suction is performed by a vacuum pump connected to the vacuum pump connector, so that the gas and / or water in the independent space is sucked to the vacuum pump connected to the vacuum pump connector through the second suction channel, the first suction channel and the vacuum pump connector, so as to suck the water after cleaning the skin.

[0063] Among them, the vacuum pump starts suctioning later than the time when the hydrator starts to output water, which can prevent premature suction from causing negative pressure in the independent space between the contact protrusion and the skin and damaging the skin, which is beneficial to protecting the skin when cleaning the skin.

[0064] Moreover, when operating the skin cleaning device for skin cleaning, the motor will be started to drive the nozzle connecting mechanism to rotate. The convex hexagonal outer wall of the nozzle connecting mechanism abuts against the inner wall of the concave hexagonal groove of the water replenishment nozzle, thereby driving the water replenishment nozzle to rotate, increasing the fluidity of the water output through the second water transfer channel, so as to better clean blackheads, acne, grease, dirt or keratin and other skin impurities on the skin.

[0065] It should be noted that the operating method of the skin cleaning device provided in the second embodiment of the present application is implemented based on the skin cleaning device provided in the first embodiment of the present application. Therefore, the technical effect achieved by the second embodiment of the present application is the same as the technical effect achieved by the first embodiment of the present application.
