Description

Technical Field

[0001] The utility model belongs to the field of beauty instruments, and in particular relates to a beauty instrument. Background Art

[0002] As a more popular beauty instrument in recent years, beauty instruments have provided greater convenience for people's skin care. When a radio frequency (RF) beauty instrument is performing skin beautification, the electrodes on it will emit electromagnetic waves and heat the skin's localized tissue, causing the subcutaneous collagen to shrink and tighten. At the same time, cooling measures are taken on the skin surface, and the dermis is heated while the epidermis maintains a normal temperature. At this time, two reactions will occur: one is that the dermis becomes thicker, and wrinkles become lighter or disappear; the other is that the subcutaneous collagen is reshaped and new collagen is produced. After treatment with the beauty instrument, the skin becomes firmer.

[0003] In the related art, in order to improve the convenience of use and reduce the cost of use, radio frequency beauty devices are miniaturized and portable, so as to be used at home. This kind of beauty device directly sets the radio frequency electrode on the skin-facing surface of the beauty device. When in use, the skin-facing surface faces or even fits the facial skin, and the radio frequency electrode on it emits radio frequency energy to the skin to stimulate the skin to achieve beauty. However, in this kind of radio frequency beauty device, the radio frequency current emitted by the radio frequency electrode is limited to a certain depth of penetration into the subcutaneous tissue, and the beauty effect is not good.

[0004] In the related technology, after further research, it was found that the use effect of the beauty instrument can be improved by negative pressure adsorption technology. In one design, a negative pressure tank and a radio frequency electrode are set on the beauty head, and an air pump is set in the main body shell of the beauty instrument. The air pump and the negative pressure tank are connected through an airway hose. During assembly, one end of the airway hose is first connected to the air pump in the main body shell, and then the other end is connected to the beauty head, and then the beauty head is installed on the main body shell. However, because in the process of installing the beauty head to the main body shell, in order to prevent the airway hose from separating from the air pump or the beauty head, great care is required, and the assembly efficiency is low.

[0005] It should be noted that the technical solutions disclosed above in this application are only for the purpose of introducing the invention purpose and effect of this application, but do not represent that they are prior art. Utility Model Content

[0066] The beauty instrument 10 can be a radio frequency beauty instrument. Its principle is to reach the bottom layer of the skin through radio frequency and activate collagen. After using the beauty instrument 10, the subcutaneous collagen is prompted to shrink and tighten, and cooling measures are taken on the skin surface. The dermis is heated while the epidermis maintains a normal temperature. At this time, two reactions will occur: one is that the dermis of the skin becomes thicker, and wrinkles become lighter or disappear; the other is that the morphology of the subcutaneous collagen is reshaped and new collagen is produced. After treatment with the beauty instrument 10, the skin becomes firmer.

[0067] In this embodiment, the beauty head 20 is detachably connected to the main body 4, the main body 4 has a first suction hole 412, the beauty head 20 includes a head shell 21 and an electrode 22 installed on the head shell 21, the head shell 21 has a suction groove 25 and a second suction hole 2122 connected to the suction groove 25, the electrode 22 is arranged adjacent to the suction groove 25, or the electrode 22 is at least partially arranged in the suction groove 25, when the beauty head 20 is installed on the main body 4, the first suction hole 412 is correspondingly connected to the second suction hole 2122 to connect with the air source component 60 inside the main body 4, the air source component 60 provides negative pressure gas, and negative pressure can be formed in the suction groove 25, so as to facilitate part of the skin to enter the suction groove 25, and the electrode 22 then emits electromagnetic waves and heats the skin positioning tissue to cause the subcutaneous collagen to shrink and tighten.

[0068] It can be understood that in order to enable the beauty instrument 10 to work normally, the beauty head 20 or the main body 4 generally has a component for increasing the radio frequency energy for the electrode, wherein, when the component is arranged on the main body 4, a first electrical connection structure can be arranged on the main body 4, and a second electrical connection structure electrically connected to the electrode 22 is arranged on the beauty head.

[0109] In some embodiments, the head shell 21 is further provided with two ventilation grooves 218, both of which are provided on the bottom wall of the accommodating cavity 211, and both of which are connected to the placement groove 2121 to avoid the phenomenon that the placement groove 2121 is blocked by the skin.

[0110] Furthermore, the beauty head 20 also includes a first temperature sensor 23 and a second temperature sensor 24, both of which are installed on the head shell 21, and the first temperature sensor 23 is arranged corresponding to the electrode 22. The first temperature sensor 23 is installed on at least one electrode sheet 221, and the first temperature sensor 23 is used to detect the temperature of the electrode 22. The second temperature sensor 24 is arranged at the bottom of the accommodating cavity 211 to detect the temperature of the human skin sucked into the accommodating cavity 211.

[0111] In some embodiments, the first temperature sensor 23 may be an NTC temperature sensor, and the second temperature sensor 24 may be an infrared temperature sensor. In this embodiment, the types and combinations of the first temperature sensor 23 and the second temperature sensor 24 are not limited, as long as they can play a normal detection function. NTC temperature sensor is a thermistor and probe, and its principle is: the resistance value drops rapidly as the temperature rises. By using this characteristic, the NTC thermistor can be used to determine the corresponding temperature by measuring its resistance value, thereby achieving the purpose of detecting and controlling the temperature, and the size of the NTC temperature sensor can be as small as 0.01 inches or a very small diameter, so that there is no need for too much installation space. Infrared temperature sensor is a thermal sensor, which uses the radiation heat effect to cause the temperature of the detection device to rise after receiving the radiation energy, thereby causing the temperature-dependent performance of the sensor to change. Therefore, when the second temperature sensor 24 is an infrared temperature sensor, it can detect the temperature of the skin without direct contact with the skin.

[0112] In some embodiments, the second temperature sensor 24 may be a non-contact temperature sensor.

[0115] The beauty head 20 also includes an anti-foolproofing portion 2143, which is protruding from the bottom of the base plate 2142 and spaced apart from the nozzle head 215. The first substrate 441 is provided with an anti-foolproofing hole 445 that matches the anti-foolproofing portion 2143. The anti-foolproofing portion 2143 is inserted into the anti-foolproofing hole 445 to prevent the beauty head 20 from being reversely installed on the main body 4.

[0116] In some embodiments, the number of beauty heads 20 is at least two, and the main body 4 is used to be detachably connected to any one of the beauty heads 20, and the other beauty head 20 can be used as a spare. The structures of the beauty heads 20 can be the same or different, so that the functions of the beauty heads 20 can also be the same or different. The beauty instrument 10 can have multiple functional options to further expand the scope of use of the beauty instrument 10.

[0117] When the number of electrode sheets 221 is two, the control component 50 also includes a first electric control block and a second electric control block. Both the first electric control block and the second electric control block are electrically connected to the controller 51. The first electric control block is used to electrically connect to one electrode sheet 221 through some Pin needles 53, and the second electric control block is used to electrically connect to another electrode sheet 221 through another part of Pin needles 53.

[0118] Furthermore, the control component 50 also includes an identification module electrically connected to the controller 51, and a plurality of pin needles 53 enclose a first group of detection points 531 and a second group of detection points 532, wherein one electrode sheet 221 is provided with a third group of detection points matching the first group of detection points 531, and another electrode sheet 221 is provided with a fourth group of detection points matching the second group of detection points 532, and the first group of detection points 531, the second group of detection points 532, the third group of detection points and the fourth group of detection points are all electrically connected to the identification module.

[0119] The control component 50 also includes a switch key 80. The main body shell 40 is also penetrated with a card-in hole. The switch key 80 is installed on the card-in hole and is electrically connected to the controller 51. Pressing the switch key 80 can make the electrode 22 emit electromagnetic waves to make the beauty instrument 10 work. When the switch key 80 is not pressed, the electrode 22 will not work.

[0120] The working principle of the beauty instrument 10:

[0121] When the beauty head 20 needs to be removed, the pressing piece 71 on the side of the main body 4 is pressed, so that the pressing piece 71 drives the movable limiting piece 73 to move laterally, so that the movable limiting piece 73 withdraws from the avoiding hole 421. At this time, the movable limiting piece 73 is separated from the nozzle head 215 on the beauty head 20, and the beauty head 20 is pulled out of the slot 411 on the main body shell 40, and finally the pressing piece 71 is released.

[0122] When the beauty head 20 needs to be installed on the main body 4, the pressing piece 71 on the side of the main body 4 is pressed, so that the pressing piece 71 drives the movable limiting piece 73 to move laterally, so that the movable limiting piece 73 withdraws from the avoiding hole 421. At this time, the plug head 215 on the beauty head 20 is inserted into the slot 411 on the main body shell 40, so that the second buckle position 216 on the plug head 215 is located in the receiving groove 422. Finally, the pressing piece 71 is released, so that the movable limiting piece 73 partially extends into the avoiding hole 421, so as to block the second buckle position 216 in the receiving groove 422, thereby realizing the installation of the beauty head 20 on the main body 4.

[0123] When in use, the beauty head 20 of the beauty instrument 10 is placed close to the skin to be treated, and the air pump 61 is used to suck the gas in the accommodating chamber 211 so that the skin to be treated is sucked into the accommodating chamber 211; when the pressure sensor 63 detects that the air pressure in the accommodating chamber 211 reaches a preset value, the air pump 61 still works, but the air pressure in the accommodating chamber 211 remains unchanged, so that the air pressure in the accommodating chamber 211 is maintained within a preset range, and then, the control electrodes 22 work alternately, and then, the air valve 62 is controlled to make the air vent of the air valve 62 connected with the accommodating chamber 211, so that external gas enters the accommodating chamber 211 through the air vent to release the skin to be treated sucked into the accommodating chamber 211.

[0124] The beneficial effects of beauty instrument 10:

[0125] 1. Each electrode pair can work alternately, so that the skin corresponding to the area enclosed by multiple electrodes 22 can be continuously electrically stimulated within a cycle, so that the skin in this area is always heated, making it equal to the skin temperature corresponding to the electrode 22, thereby improving the balance of beauty and enhancing the user experience.

[0126] 2. The beauty instrument 10 is provided with a first temperature sensor 23 and a second temperature sensor 24. The first temperature sensor 23 is connected to the electrode 22 to detect the temperature of the electrode 22. The second temperature sensor 24 is used to detect the temperature of human skin. Therefore, when detecting the temperature of the skin, the temperature of the electrode 22 can also be detected at the same time, which effectively avoids the influence of the excessive temperature of the electrode 22 on the skin temperature, improves the accuracy of the temperature detection of the beauty instrument 10, thereby effectively and timely controlling the skin temperature and enhancing the user experience.

[0127] 3. Since the arrangement of the electrodes 22 of each beauty head 20 is different, the beauty head 20 can be removed from the main body 4 through the detachable component 70, so that different types of beauty heads 20 can be replaced according to the needs of different users, thereby increasing the use function of the beauty instrument 10, expanding the scope of use, and being able to keep the beauty head 20 clean and hygienic at all times, thereby improving the user experience.
