[0002] Radio frequency beauty devices mainly stimulate the dermis to produce collagen through radio frequency heating, thereby achieving the effect of tightening the skin and reducing wrinkles. Traditional radio frequency beauty devices are mainly large medical equipment, mainly used in hospitals or beauty salons, and are gradually unable to meet the needs of most people.

[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.

[0063] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0064] Figure 1 A schematic structural diagram of a beauty instrument 001 in one embodiment of the present application is shown.

[0065] like Figure 1 As shown, the beauty instrument 001 includes a main body 010 and a beauty head 030. The beauty head 030 includes a negative pressure groove 4111 and a radio frequency electrode 420. The negative pressure groove 4111 is used to absorb the user's skin with negative pressure to absorb the skin into the negative pressure groove 4111. The radio frequency electrode 420 is used to release radio frequency current to the user's skin. The beauty head 030 is detachably arranged at the working end 011 of the main body 010. When the beauty head 030 is connected to the main body 010, the negative pressure groove 4111 is connected to the main body 010 to generate negative pressure, and the radio frequency electrode 420 is electrically connected to the main body 010 so that the main body 010 provides electrical energy to the radio frequency electrode 420.

[0066] This beauty instrument 001 is a radio frequency beauty instrument 001. When the head is set at the working end 011 of the main body 010, the beauty head 030 can act on the user's skin. The main body 010 provides negative pressure to the beauty head 030, so that the user's skin is adsorbed on the beauty head 030, and the beauty head 030 transmits radio frequency current to the user's skin to achieve a beauty effect.

[0067] Specifically, when using the beauty instrument 001, the beauty head 030 is detachably connected to the main body 010 to achieve electrical connection between the radio frequency electrode 420 and the main body 010 and communication between the negative pressure groove 4111 and the main body 010, so that the main body 010 can absorb the skin into the negative pressure groove 4111 through the negative pressure groove 4111, and then send radio frequency current to the skin after absorption through the radio frequency electrode 420, so that the radio frequency current can penetrate the skin absorbed into the negative pressure groove 4111, thereby increasing the injection depth of radio frequency energy, thereby improving the beauty effect. The detachable connection between the beauty head 030 and the main body 010 allows the beauty head 030 to be separated from the main body 010 and stored separately. When it is needed, the beauty head 030 and the main body 010 are assembled again to achieve electrical connection between the radio frequency electrode 420 and the main body 010 and communication between the negative pressure groove 4111 and the main body 010. In addition, through the detachable connection between the beauty head 030 and the main body 010, the user can replace different beauty heads 030 according to usage needs, such as replacing the beauty head 030 with a different negative pressure groove 4111, or replacing the beauty head 030 with a different number of radio frequency electrodes 420, or replacing the beauty head 030 with radio frequency electrodes 420 of different sizes, etc., so as to meet the diverse needs of users.

[0068] It can be understood that, in the present application, the beauty head 030 and the main body 010 are designed to be separate, and the negative pressure tank 4111 is provided on the beauty head 030. When the beauty head 030 is installed on the main body 010, the negative pressure tank 4111 can be connected with the main body 010, so there is no need to consider whether the airway hose is separated from the beauty head 030 or the air pump 510, thereby improving the assembly efficiency.

[0069] Specifically, the beauty head 030 has a skin-contacting surface 410c that faces toward or even contacts the facial skin during operation, and the radio frequency electrode 420 and the negative pressure groove 4111 are disposed on the skin-contacting surface 410c.

[0070] The beauty instrument 001 further includes a control component for controlling the operation of the radio frequency electrode 420 , etc. Optionally, the control component is disposed in the housing 100 to form a part of the main body 010 .

[0071] Furthermore, the main body 010 includes a first electrical connector 240, and the beauty head 030 also includes a second electrical connector 470, and the second electrical connector 470 is electrically connected to the RF electrode 420. When the beauty head 030 is connected to the main body 010, the first electrical connector 240 is electrically connected to the second electrical connector 470, so that the main body 010 provides electrical energy to the RF electrode 420. In this way, the RF electrode 420 can be controlled by the first electrical connector 240 and the second electrical connector 470.

[0072] Further, the main body 010 includes a first airflow connection part 232, and the beauty head 030 also includes a second airflow connection part 4114 connected to the negative pressure groove 4111. When the beauty head 030 is connected to the main body 010, the first airflow connection part 232 is connected to the second airflow connection part 4114, so that the negative pressure groove 4111 is connected to the main body 010. In this way, by providing the first airflow connection part 232 on the beauty head 030 and providing the first airflow connection part 232 connected to the airflow driving member on the main body 010, it can be achieved that when the beauty head 030 is installed on the main body 010, the first airflow connection part 232 is connected to the second airflow connection part 4114 to achieve the connection between the main body 010 and the negative pressure groove 4111, thereby further reducing the difficulty of assembly.

[0073] Further, the RF electrode 420 is arranged close to the negative pressure groove 4111, or the RF electrode 420 at least partially extends to the inner wall of the negative pressure groove 4111, so that the RF electrode 420 releases RF current to the skin adsorbed by the negative pressure of the negative pressure groove 4111. The RF electrode 420 is arranged close to the negative pressure groove 4111 so that the distance between the RF electrode 420 and the inner wall of the negative pressure groove 4111 is less than or equal to 12 mm. In this way, by arranging the RF electrode 420 close to the negative pressure groove 4111, or by extending the RF electrode 420 at least partially to the inner wall of the negative pressure groove 4111, the RF path can be reduced and the cosmetic effect can be improved.

[0074] The first electrical connector 240 and the first airflow connector 232 constitute a part of the connection module 200 described below.

[0075] The main body 010 includes a connection module 200, and the beauty head 030 is detachably connected to the connection module 200, so that the beauty head 030 is detachably connected to the main body 010. The first electrical connector 240 and the first airflow connection portion 232 are all part of the connection module 200.

[0076] It should be noted that the connection module 200 mentioned in the present application can be either an independent module or a feature set formed by relying on other features of the main body 010. Its relationship with other components is mutually dependent. It is listed separately only for the convenience of description.

[0077] In some embodiments, the first airflow connection part 232 and the second airflow connection part 4114 can be detachably connected so that the first airflow connection part 232 and the second airflow connection part 4114 are connected. In this way, when the beauty head 030 is installed on the main body 010, the first airflow connection part 232 and the second airflow connection part 4114 are connected so that the first airflow connection part 232 and the second airflow connection part 4114 are connected; when the beauty head 030 needs to be removed, the first airflow connection part 232 and the second airflow connection part 4114 can be removed. For example, one of the first airflow connection part 232 and the second airflow connection part 4114 can be a nozzle, and the other can be an airway connection member with a socket, and the nozzle can be inserted into the socket. Of course, the first airflow connection part 232 and the second airflow connection part 4114 can also be set to other structural forms, as long as it is satisfied that when the beauty head 030 is installed / connected to the main body 010, the first airflow connection part 232 and the second airflow connection part 4114 are connected and communicated, and when the beauty head 030 is removed, the first airflow connection part 232 and the second airflow connection part 4114 can be separated.

[0078] In some embodiments, the ventilation area of ​​the connection channel of the second airflow connection portion 4114 is smaller than the notch area of ​​the negative pressure groove 4111. The ventilation area of ​​the connection channel of the second airflow connection portion 4114 refers to the ventilation area of ​​the connection channel at the connection with the first airflow connection portion 232. In this way, the negative pressure groove 4111 can have a larger adsorption area, and the channel for sucking gas is thinner, so as to facilitate connection with the air pump 510 and control the suction of the negative pressure groove 4111.

[0079] Furthermore, the main body 010 has a first assembly surface 212b, and the beauty head 030 has a second assembly surface 412a. When the beauty head 030 is connected to the main body 010, the first assembly surface 212b and the second assembly surface 412a are arranged correspondingly.

[0080] The first electrical connector 240 is exposed from the first assembly surface 212b to the main body 010 , and the second electrical connector 470 is exposed from the second assembly surface 412a to the beauty head 030 , so that when the beauty head 030 is connected to the main body 010 , the first electrical connector 240 and the second electrical connector 470 are electrically connected.

[0081] The first airflow connection part 232 is exposed from the first assembly surface 212b to the main body 010 , and the second airflow connection part 4114 is exposed from the second assembly surface 412a to the beauty head 030 , so that when the beauty head 030 is connected to the main body 010 , the first airflow connection part 232 is connected to the second airflow connection part 4114 .

[0082] It can be understood that the first assembly surface 212b and the second assembly surface 412a are respectively restricted by the shapes of the main body 010 and the beauty head 030, but as long as the first assembly surface 212b and the second assembly surface 412a are arranged correspondingly when the beauty head 030 is connected to the main body 010. For example, the beauty head 030 has an opposite surface arranged opposite to the skin contact surface 410c, and the opposite surface can form the second assembly surface 412a, and the first assembly surface 212b can also be the surface of the main body 010 facing the facial skin during operation; for another example, when the main body 010 is formed with an assembly groove 212a, the first assembly surface 212b can be the bottom of the assembly groove 212a or the inner peripheral wall of the assembly groove 212a.

[0083] In this way, by making the first electrical connector 240 exposed to the main body 010 from the first assembly surface 212b, and the second electrical connector 470 exposed to the beauty head 030 from the second assembly surface 412a, it is possible to achieve electrical connection between the first electrical connector 240 and the second electrical connector 470 when the beauty head 030 is mounted on the main body 010. By making the first airflow connection part 232 exposed to the main body 010 from the first assembly surface 212b, and the second airflow connection part 4114 exposed to the beauty head 030 from the second assembly surface 412a, it is possible to achieve communication between the first airflow connection part 232 and the second airflow connection part 4114 when the beauty head 030 is mounted on the main body 010, thereby improving the convenience of use.

[0084] Specifically, when the beauty head 030 is connected to the main body 010, the first assembly surface 212b contacts or abuts against the second assembly surface 412a, so that the beauty head 030 and the main body 010 are easily positioned.

[0085] Further, when the beauty head 030 is connected to the main body 010, the first assembly surface 212b and the second assembly surface 412a are arranged correspondingly in the disassembly direction. The disassembly direction is the direction in which the beauty head 030 moves away from or approaches the main body 010 when the beauty head 030 and the main body 010 are disassembled or installed. For example, when the second assembly surface 412a is the above-mentioned opposite surface, the first assembly surface 212b is the side of the main body 010 facing the facial skin during operation and opposite to the above-mentioned opposite surface; when the first assembly surface 212b is the bottom of the above-mentioned assembly groove 212a, the second assembly surface 412a is the side of the beauty head 030 corresponding to the bottom (such as the above-mentioned opposite surface). The disassembly direction can be parallel to the first inclined direction U. Optionally, when the disassembly direction is parallel to the first inclined direction U, at least one of the first electrical connector 240 and the first airflow connection portion 232 extends along the first inclined direction U.

[0086] Furthermore, the first electrical connector 240 and the second electrical connector 470 are in contact or abutment with each other in the disassembly direction, so that when the beauty head 030 is connected to the main body 010, the first electrical connector 240 and the second electrical connector 470 are electrically connected. This facilitates the electrical connection of the first electrical connector 240 and the second electrical connector 470.

[0087] Furthermore, the first airflow connection part 232 and the second airflow connection part 4114 are butted against each other in the disassembly direction, so that when the beauty head 030 is connected to the main body 010, the first airflow connection part 232 and the second airflow connection part 4114 are connected. This facilitates the connection of the first airflow connection part 232 and the second airflow connection part 4114.

[0088] In this way, the risk of damaging the first electrical connector 240, the second electrical connector 470, the first airflow connection part 232 and the second airflow connection part 4114 during the process of disassembling and assembling the beauty head 030 can be reduced, and the design difficulty of the first electrical connector 240, the second electrical connector 470, the first airflow connection part 232 and the second airflow connection part 4114 can be reduced, thereby reducing the design cost.

[0089] In some embodiments, the beauty head 030 or the main body 010 is provided with an assembly groove 212a, and the bottom of the assembly groove 212a forms a first assembly surface 212b or a second assembly surface 412a, so that the beauty head 030 is at least partially installed in the assembly groove 212a of the main body 010 or the main body 010 is installed in the assembly groove 212a of the beauty head 030, and the relative position of the connection module 200 and the beauty head 030 is limited. In this way, by providing the assembly groove 212a, when working, the facial skin will contact the beauty head 030, and by providing the assembly groove 212a, the side wall of the assembly groove 212a can be used to support the beauty head 030, which can help improve the setting stability of the beauty head 030, thereby improving the stability during operation.

[0090] Specifically, the first assembly surface 212 b is provided on the connection module 200 .

[0091] Specifically, the connection module 200 or the beauty head 030 is provided with an assembly groove 212a, and the bottom / bottom wall of the assembly groove 212a forms a first assembly surface 212b or a second assembly surface 412a, so that the beauty head 030 can be loaded into the assembly groove 212a of the connection module 200 or the connection module 200 can be loaded into the assembly groove 212a of the beauty head 030, and the relative position of the connection module 200 and the beauty head 030 can be limited.

[0092] Furthermore, there are many ways to detachably connect the first airflow connection part 232 and the second airflow connection part 4114. For example, when the beauty head 030 is connected to the main body 010, the first airflow connection part 232 is inserted into the second airflow connection part 4114, or the second airflow connection part 4114 is inserted into the first airflow connection part 232, so that the first airflow connection part 232 is connected to the second airflow connection part 4114. In this way, the detachable connection can be quickly realized by plug-in, and it is easy to seal.

[0093] For example, in one embodiment, the connection module 200 is provided with an assembly groove 212a, the bottom wall of the assembly groove 212a forms a first assembly surface 212b, and the first airflow connection portion 232 protrudes from the first assembly surface 212b to be inserted into the second airflow connection portion 4114, so that the first airflow connection portion 232 is communicated with the second airflow connection portion 4114. In another embodiment, the beauty head 030 is provided with an assembly groove 212a, the bottom wall of the assembly groove 212a forms a second assembly surface 412a, and the second airflow connection portion 4114 protrudes from the second assembly surface 412a to be inserted into the first airflow connection portion 232, so that the first airflow connection portion 232 is communicated with the second airflow connection portion 4114.

[0094] Figure 2 A schematic diagram of an exploded view of a beauty instrument 001 in one embodiment of the present application is shown. Figure 3 A schematic diagram of an exploded view of the beauty instrument 001 in one embodiment of the present application is shown from another perspective.

[0095] See also Figure 2 and Figure 3 The main body 010 includes a shell 100. The shell 100 includes a first half shell, a second half shell and a head shell 110. The first half shell and the second half shell may not be strictly divided into halves, that is, the first half shell may be significantly larger than the second half shell, or significantly smaller than the second half shell, and even one of the first half shell and the second half shell may be a plate-like structure.

[0096] Furthermore, one end of the first half shell has a bending portion 121 that is bent and inclined toward a side close to the second half shell and is arranged in the first inclined direction U. The bending portion 121 can adapt to the head shell 110 to assemble the head shell 110, the first half shell and the second half shell.

[0097] For ease of description, Figure 1In this state, the first half shell is defined as the rear shell 120, and the second half shell is defined as the front shell 130. The rear shell 120 extends as a whole along the first direction X, the front shell 130 extends as a whole along the first direction X, the bending portion 121 is bent forward and tilted, and the head shell 110 is arranged forward tilted, so that the head shell 110 can be provided with a plurality of RF electrodes 420 arranged forward tilted, so as to release RF current to the user's skin through the RF electrodes 420. The plurality of RF electrodes 420 arranged forward tilted means that the plurality of RF electrodes 420 are arranged tilted toward the side of the first half shell close to the second half shell.

[0098] The front shell 130 and the rear shell 120 cooperate to form a holding portion 101, which is convenient for the user to hold the beauty instrument 001. The bending portion 121 protrudes from the front shell 130, and the head shell 110 is connected to the bending portion 121 and the front shell 130. Specifically, the holding portion 101 extends along the first direction X, and the bending portion 121 is located at one end of the holding portion 101 and extends obliquely to the first direction X. Specifically, the front shell 130 does not directly cooperate with the bending portion 121, so that after the front shell 130 and the rear shell 120 are connected, the bending portion 121 is in a state of protruding from the front shell 130.

[0099] Specifically, the head shell 110 has a skin-facing plate 011a. When the beauty instrument 001 needs to act on the skin, the skin-facing plate 011a faces the user's skin.

[0100] In some embodiments, Figure 2 and Figure 3 As shown, the head shell 110 is used to install the beauty head 030, such as the beauty head 030 can be installed on the skin-facing plate 011a; in another embodiment, as shown in FIG. Fig.30 and Fig.31 As shown, the head shell 110 is used to form the beauty head 030, on which (specifically, the skin-facing plate 011a) is used to install the radio frequency electrode 420 and the cold compress 910, etc.

[0101] Specifically, the head shell 110 has an assembly recess 5122 that cooperates with the bending portion 121 , and the head shell 110 is detachably mounted on the bending portion 121 and the second half shell 517 through the assembly recess 5122 .

[0102] In this way, by providing the first half shell with a bent portion 121 protruding from the second half shell, and correspondingly providing the head shell 110 with an assembly notch 5122 for use, the head shell 110, the first half shell, and the second half shell can be combined to form the accommodating cavity 100a of the outer shell 100. Moreover, through this arrangement, when manufacturing the head shell 110, it is easy to demould the head shell 110, thereby reducing the manufacturing difficulty; and during assembly, due to the arrangement of the assembly notch 5122, the assembly space can be increased, so as to facilitate the installation of features such as the RF electrode 420 and the cold compress 910; or to facilitate the installation of the connection module 200.

[0103] The following mainly focuses on Figure 2 and Figure 3 The head shell 110 shown is used to illustrate an embodiment in which the beauty head 030 is mounted.

[0104] exist Figure 2 and Figure 3 In the illustrated embodiment, the head shell 110 includes a base plate 110b and a surrounding plate 110c, the base plate 110b is used to form the skin facing plate 011a, that is, the base plate 110b is the skin facing plate 011a, and the assembly recess 5122 is formed in the surrounding plate 110c. In some embodiments, the surrounding plate 110c is connected to the periphery of the base plate 110b, so that the head shell 110 is generally a hollow structure.

[0105] The enclosure 110c includes an enclosure body 111 and an assembly 113. The enclosure body 111 is a hollow structure, connected to the periphery of the base plate 110b, and the interior cooperates with the base plate 110b to form an installation cavity 110a, so as to install a connection module 200 used to cooperate with the beauty head 030. The assembly 113 is arranged at one end of the enclosure body 111, and is used to cooperate with the rear shell 120 and the front shell 130, so as to connect the rear shell 120 and the front shell 130 to the head shell 110.

[0106] The connection module 200 is exposed from the other end of the enclosure body 111, so as to facilitate the connection between the beauty head 030 and the connection module 200. The end of the enclosure body 111 away from the assembly 113 is flatly arranged so that the connection module 200 is accommodated in the installation cavity 110a and exposed from the end of the installation cavity 110a away from the assembly 113.

[0107] Optionally, the assembly part 113 and the enclosure body 111 are integrally formed to improve the strength of the head shell 110 and facilitate the production and preparation of the head shell 110 .

[0108] The assembly 113 includes a first head shell assembly portion 1131 and a second head shell assembly portion 1132. The first head shell assembly portion 1131 is used to connect with the rear shell 120, and the second head shell assembly portion 1132 is used to connect with the front shell 130. When the head shell 110, the front shell 130 and the rear shell 120 are connected, the front shell 130 and the rear shell 120 extend approximately along the first direction X, and the head shell 110 extends along the first inclined direction U, which is inclined to the first direction X. The angle between the first inclined direction U and the first direction X is 20-80°, such as 22°, 24°, 26°, 28°, 30°, 32°, 34°, 36°, 38°, 40°, 42°, 44°, 46°, 48°, 50°, 52°, 54°, 56°, 58°, 60°, 62°, 64°, 66°, 68°, 70°, 75°, 78° or 80°, etc.

[0109] In one embodiment, the included angle between the first inclined direction U and the first direction X can be selected to be 36°-63°. Optionally, the included angle between the first inclined direction U and the first direction X is 37°.

[0110] It can be understood that since the head shell 110 is used to install the beauty head 030 or to form the beauty head 030, by making the angle between the first inclined direction U and the first direction X 20-80° or 36°-63°, the skin-contacting surface 410c of the beauty head 030 can also be inclined, so that when the user holds the beauty instrument 001 and acts on the face, the arm can be avoided from being raised too high, thereby achieving more labor-saving beauty.

[0111] In summary, through the above configuration, on the one hand, after the head shell 110 is equipped with the beauty head 030, when the user holds the holding portion 101 formed by the front shell 130 and the rear shell 120, it is convenient for the beauty head 030 to act on the user's skin (such as face), and it is labor-saving to do not need to raise the arm. On the other hand, the size of the beauty instrument 001 in the second direction Y can be kept in a small range, which is convenient for storing the beauty instrument 001.

[0112] The first inclined direction U is located between the first direction X and the second direction Y, and the second direction Y is perpendicular to the first direction X. The first direction X forms the length direction of the beauty instrument 001. The second direction Y forms the thickness direction of the beauty instrument 001. The third direction Z perpendicular to the first direction X and the second direction Y forms the width direction of the beauty instrument 001.

[0113] Figure 4 A schematic diagram of an exploded view of a housing 100 of a beauty instrument 001 in one embodiment of the present application is shown.

[0114] Please refer to Figure 3 and Figure 4 , along the second inclined direction V perpendicular to the first inclined direction U, from far away from the second head shell assembly part 1132 to close to the second head shell assembly part 1132, the first head shell assembly part 1131 includes a first head shell area 11311, a second head shell area 11312 and a third head shell area 11313. The first head shell area 11311 and the second head shell area 11312 are arranged at an obtuse angle, and the second head shell area 11312 and the third head shell area 11313 are arranged at an obtuse angle to form an assembly recess 11314, and the assembly recess 11314 is set in an enlarged shape to further facilitate demoulding and increase assembly space.

[0115] The notch formed by the first head shell area 11311 in the head shell 110 is substantially perpendicular to the first tilting direction U. The notch formed by the second head shell area 11312 in the head shell 110 is substantially perpendicular to the second direction Y. The notch formed by the third head shell area 11313 in the head shell 110 is substantially perpendicular to the first tilting direction U.

[0116] The first head shell area 11311 and the second head shell area 11312 are in arc transition, and the second head shell area 11312 and the third head shell area 11313 are in arc transition, so as to facilitate demoulding.

[0117] Among them, the area between the first head shell area 11311 and the second head shell area 11312 forms an assembly recess 11314.

[0118] Specifically, the size of the portion of the head shell 110 corresponding to the second head shell area 11312 in the first tilt direction U gradually increases from close to the first head shell area 11311 to close to the third head shell area 11313.

[0119] Specifically, along the first inclined direction U, the extension dimension of the enclosing plate body 111 corresponding to the first head shell area 11311 is smaller than the extension dimension of the enclosing plate body 111 corresponding to the second head shell area 11312. Along the first inclined direction U, the extension dimension of the enclosing plate body 111 corresponding to the second head shell area 11312 is smaller than the extension dimension of the enclosing plate body 111 corresponding to the third head shell area 11313, so as to form the assembly recess 11314.

[0120] The assembly notch 11314 of the head shell 110 is used to cooperate with the bending portion 121 for connection.

[0121] It is understandable that the assembly recess 11314 can also be formed on the base plate 110b and the enclosure 110c. In some embodiments, the enclosure 110c protrudes and is connected to a portion of the periphery of the base plate 110b, and the assembly recess 11314 can be formed at a position between the base plate 110b and the enclosure 110c.

[0122] Furthermore, the portion of the head shell 110 corresponding to the first head shell region 11311 extends a smaller dimension in the first inclined direction U, so that when assembling the head shell 110 and the connection module 200, it is convenient for a tool to extend into the head shell 110 from the notch corresponding to the first head shell region 11311, thereby reducing assembly difficulty and cost and improving assembly yield. In addition, the head shell 110 is also easy to demold during production.

[0123] In the present application, the head shell 110 can be produced by injection molding. After injection molding, when the head shell 110 is demolded, since the head shell 110 is formed with an assembly recess 11314, it is convenient to demold, such as facilitating the head shell 110 to be demolded along the first inclined direction U or from the first head shell area 11311 to the second head shell area 11312.

[0124] The first head shell assembly portion 1131 transitions to the second head shell assembly portion 1132 through the third head shell region 11313, so that the rear shell 120 is assembled to the head shell 110 and connected to the front shell 130 at the same time. The arc transition means that the part transitioning from one area to another area is arc-shaped, wherein the first head shell region 11311 and the second head shell region 11312 are arc-shaped transitions, and the contour of the connection between the first head shell region 11311 and the enclosure body 111 transitions to the contour of the connection between the second head shell region 11312 and the enclosure body 111 is arc-shaped, thereby preventing the tip from being deformed when demolding and facilitating alignment and assembly.

[0125] The rear shell 120 is provided with a first rear shell assembly portion 1201 , and the first rear shell assembly portion 1201 is used to cooperate with the first head shell assembly portion 1131 , so as to realize the connection between the head shell 110 and the rear shell 120 .

[0126] The rear shell 120 has a first accommodating groove 120 a , and the front shell 130 has a second accommodating groove 130 a . The first accommodating groove 120 a and the second accommodating groove 130 a together form an accommodating cavity 100 a between the front shell 130 and the rear shell 120 .

[0127] The first rear shell assembly portion 1201 includes a first rear shell area 12011, a second rear shell area 12012 and a third rear shell area 12013. The first rear shell area 12011 corresponds to the first head shell area 11311, and the second rear shell area 12012 corresponds to the second head shell area 11312, that is, the first rear shell area 12011 and the second rear shell area 12012 correspond to the assembly recess 11314, and the third rear shell area 12013 corresponds to the third head shell area 11313. Optionally, the first rear shell area 12011 and the second rear shell area 12012 have an arc transition.

[0128] When the back shell 120 is connected to the head shell 110, the notch formed in the first back shell area 12011 is roughly perpendicular to the extension direction, the notch formed in the second back shell area 12012 is roughly perpendicular to the second direction Y, and the notch formed in the third back shell area 12013 is roughly perpendicular to the extension direction.

[0129] Among them, the first rear shell area 12011 , the second rear shell area 12012 and the third rear shell area 12013 are formed in the bending portion 121 .

[0130] When assembling the front shell 130, the rear shell 120 and the head shell 110, the rear shell 120 can be moved close to the head shell 110 along the second direction Y so that the head shell 110 is connected to the rear shell 120, and connected to the front shell 130 so that the first accommodating groove 120a and the second accommodating groove 130a form an accommodating cavity 100a.

[0131] The first head shell assembly part 1131 is provided with a first head shell engaging member 11315, and the back shell 120 is provided with a first back shell engaging member 12015 at the first back shell assembly part 1201. The first head shell engaging member 11315 and the first back shell engaging member 12015 are engaged and matched, so that the head shell 110 and the back shell 120 can be engaged.

[0132] The outer wall surface of the first head shell assembly portion 1131 is not coplanar with the outer wall surface of the enclosure body 111 , so that a first step is formed between the first head shell assembly portion 1131 and the enclosure body 111 .

[0133] When the rear shell 120 is connected to the head shell 110, the rear shell 120 fits against the bottom wall of the first step, and one end of the rear shell 120 close to the head shell 110 abuts against the side wall of the first step. The bottom wall of the first step is the periphery of the first head shell assembly portion 1131, and the side wall of the first step is the end surface of the enclosure body 111 facing the first head shell assembly portion 1131. The rear shell 120 abuts against the side wall of the first step, which can limit the movement of the rear shell 120 relative to the head shell 110 along the first direction X, and can facilitate the outer wall surface of the rear shell 120 to be coplanar or smoothly transitioned with the outer wall surface of the enclosure body 111, thereby improving the flatness of the appearance of the shell 411.

[0134] Optionally, the first head shell engaging member 11315 is a locking hole, and the first rear shell engaging member 12015 is a buckle. The buckle can be elastically deformed to enter the locking hole, and after the buckle is locked into the locking hole, the buckle elastically restores its shape to achieve the locking of the buckle and the locking hole.

[0135] Optionally, the first head shell assembly part 1131 is provided with a first head shell fitting part, and the back shell 120 is provided with a first back shell fitting part in the first back shell assembly part 1201. The first head shell fitting part and the first back shell fitting part fit tightly together, so that the head shell 110 and the back shell 120 can be connected. Optionally, the first head shell fitting part is a magnetic part, and the first back shell fitting part is a magnetic part. The first head shell fitting part and the first back shell fitting part can fit together magnetically. Optionally, the first head shell fitting part is an adhesive part, and the first back shell fitting part is an adhesive surface. The first head shell fitting part and the first back shell fitting part can fit together by adhesion.

[0136] When the front shell 130 is connected to the head shell 110, the front shell 130 extends approximately along the first direction X. Along the second direction Y, the size of the front shell 130 is 0.2-0.25 times the size of the rear shell 120. The first accommodating groove 120a of the rear shell 120 constitutes most of the accommodating cavity 100a, while the second accommodating groove 130a of the front shell 130 constitutes only a small part of the accommodating cavity 100a. When it is necessary to detach the outer shell 100 to maintain the beauty instrument 001, only the rear shell 120 is detached, so that the internal components of the beauty instrument 001 can be exposed, and a larger operation window is formed at the position where the rear shell 120 is detached for operation, such as maintenance.

[0137] Specifically, the front shell 130 is further provided with a first front shell assembly part 1301. The first front shell assembly part 1301 cooperates with the second head shell assembly part 1132 to assemble the front shell 130 and the head shell 110. The second head shell assembly part 1132 is provided with a second head shell clamping part 11321, and the first front shell assembly part 1301 is provided with a first front shell clamping part 13011.

[0138] In this way, the head shell 110 and the front shell 130 can be engaged with each other through the engagement and cooperation between the second head shell engaging piece 11321 and the first front shell engaging piece 13011.

[0139] Specifically, a second step is formed between the second head shell assembly portion 1132 and the enclosure body 111. When the front shell 130 is connected to the head shell 110, the front shell 130 fits against the bottom wall of the second step, and one end of the front shell 130 close to the head shell 110 abuts against the side wall of the second step. The bottom wall of the second step is the outer periphery of the second head shell assembly portion 1132, and the side wall of the second step is the end face of the enclosure body 111 facing the second head shell assembly portion 1132.

[0140] In this way, the front shell 130 abuts against the side wall of the second step, so that the front shell 130 can be restricted from moving along the first direction X relative to the head shell 110 .

[0141] Optionally, the second head shell assembly part 1132 is provided with a second head shell fitting part, and the first front shell assembly part 1301 is provided with a first front shell fitting part. The second head shell fitting part and the first front shell fitting part fit tightly together, so that the head shell and the front shell fit together. Optionally, the second head shell fitting part is a magnetic part, and the first front shell fitting part is a magnetic part. The second head shell fitting part and the first front shell fitting part can fit together magnetically. Optionally, the second head shell fitting part is an adhesive part, and the first front shell fitting part is an adhesive surface. The second head shell fitting part and the first front shell fitting part can fit together by adhesion.

[0142] It is understandable that the head shell 110 may not be provided with the assembly 113, and the connection with the front shell 130 or the rear shell 110 may be achieved in other ways. For example, a magnetic member is embedded in the head shell 110, and the head shell 110 and the rear shell 120 are connected by magnetic attraction, and the head shell 110 and the front shell 130 are connected by magnetism.

[0143] Figure 5 Shows Figure 4 A partial enlarged view of area A.

[0144] Please refer to Figure 4 and Figure 5 , selectively, the second head shell engaging member 11321 is a engaging groove, and the first front shell engaging member 13011 is a engaging block.

[0145] Specifically, the engaging groove is roughly T-shaped, and has a first head shell engaging section 11322 and a second head shell engaging section 11323 along the first direction X. The size of the engaging block matches the engaging groove. When the engaging block is inserted into the engaging groove along the second direction Y, the engaging groove will limit the engaging block from falling off the engaging groove along the first direction X, thereby limiting the front shell 130 from moving away from the head shell 110 along the first direction X. Moreover, the T-shaped engaging structure has a greater structural strength and a higher engaging stability.

[0146] Optionally, the dimension of the first head shell snap-fitting section 11322 along the third direction Z is greater than the dimension of the second head shell snap-fitting section 11323 along the third direction Z.

[0147] Optionally, the front shell 130 is further provided with a locking member 1304, and the locking member 1304 is locked to the second head shell assembly portion 1132 to limit the relative movement of the front shell 130 and the head shell 110 along the second direction Y.

[0148] Optionally, the extension direction of the second head shell assembly portion 1132 is inclined to the second direction Y.

[0149] When the front shell 130 is connected to the head shell 110 , the enclosure body 111 can also abut against the front shell 130 in the second direction Y to limit the front shell 130 from separating from the head shell 110 along the second direction Y.

[0150] The extension direction of the second head shell assembly part 1132 is inclined at an angle of 3-10° to the second direction Y. Optionally, the extension direction of the second head shell assembly part 1132 is inclined at an angle of 6° to the second direction Y, so that the front shell 130 cooperates with the head shell 110 along the second direction Y, and the enclosure body 111 can abut against the front shell 130 in the second direction Y to limit the front shell 130 from detaching from the head shell 110 along the second direction Y. The extension direction of the second head shell assembly part 1132 is the direction in which the second head shell assembly part 1132 extends away from the first head shell assembly part 1131.

[0151] Furthermore, if Figure 3 and Figure 4 As shown, the front shell 130 has a tail cover portion 131 at one end away from the head shell 110. In this way, when the front shell 130 is disassembled, more operating space can be exposed to facilitate assembly or maintenance.

[0152] Furthermore, if Figure 3 and Figure 4 As shown, the tail cover portion 131 is inclined in the first direction X and extends in the direction of the rear shell 120. Correspondingly, in one embodiment, the size of the rear shell 120 in the first direction X gradually increases from a position close to the front shell 130 to a position far away from the front shell 130. The size of the end of the rear shell 120 close to the front shell 130 along the first direction X is the smallest.

[0153] In this way, when the front shell 130 is connected to the head shell 110, a flare is formed at the connection between the front shell 130 and the head shell 110, that is, the assembly dimension along the first direction X increases from approaching the front shell 130 to being away from the front shell 130 along the second direction Y, so that it is convenient to assemble the rear shell 120 at the flared portion. It can be understood that if the assembly dimension along the first direction X decreases from approaching the front shell 130 to being away from the front shell 130 along the second direction Y, it is easy to cause a position conflict with the rear shell 120, resulting in the difficulty of the rear shell 120 to be assembled in the assembly space formed by the front shell 130 and the head shell 110. In the present application, when the front shell 130 is connected to the head shell 110, an opening is formed between the tail cover part 131 and the head shell 110, and the rear shell 120 approaches the opening from the end with the smallest dimension in the first direction X, so that the rear shell 120 can be assembled to the front shell 130 and the head shell 110.

[0154] Furthermore, if Figure 3 and Figure 4 As shown, the front shell 130 further has a second front shell assembly portion 1302 , and the second front shell assembly portion 1302 is used to cooperate with the rear shell 120 to fix the relative position of the front shell 130 and the rear shell 120 .

[0155] Wherein, along the first direction X, from close to the head shell to far away from the head shell, the second front shell assembly part 1302 sequentially includes a first front shell area 13021 and a second front shell area 13022. The first front shell area 13021 extends as a whole parallel to the first direction, and when the front shell 130 is connected to the head shell 110, the first front shell area 13021 of the second front shell assembly part 1302 and the second head shell assembly part 1132 transition in an arc shape.

[0156] Furthermore, if Figure 3 and Figure 4As shown, the second front shell area 13022 of the second front shell assembly part 1302 is located at the tail cover part 131 . Specifically, the second front shell area 13022 is arranged along the outer periphery of the tail cover part 131 , and the first front shell area 13021 and the second front shell area 13022 are in an arc transition.

[0157] Furthermore, if Figure 3 and Figure 4 As shown, the rear shell 120 also has a second rear shell assembly part 1202. Along the first direction X, from close to far away from the head shell, the second rear shell assembly part 1202 sequentially includes a fourth rear shell area 12021 and a fifth rear shell area 12022. The fourth rear shell area 12021 of the rear shell 120 matches the first front shell area 13021 of the assembly part. The fifth rear shell area 12022 of the rear shell 120 matches the second front shell area 13022 of the assembly part.

[0158] When the rear shell 120 is connected to the front shell 130, the fourth rear shell area 12021 is connected to the first front shell area 13021, and the fifth rear shell area 12022 is connected to the second front shell area 13022, so that the first receiving groove 120a and the second receiving groove 130a together form the receiving cavity 100a between the front shell 130 and the rear shell 120. After the second front shell area 13022 and the fifth rear shell area 12022 are connected, the tail cover part 131 closes the end of the receiving cavity 100a away from the head shell 110, thereby reducing the risk of foreign matter entering the receiving cavity 100a.

[0159] Optionally, the front shell 130 may also be provided with a functional hole in the tail cover part 131, through which the power cord 050 may be introduced into the accommodating chamber 100a, so as to supply power to the accommodating chamber 100a. Optionally, the front shell 130 may also be provided with a ventilation hole in the tail cover part 131, and the ventilation hole enables gas exchange between the accommodating chamber 100a and the outside of the beauty instrument 001, so as to facilitate heat dissipation and pressure relief of the beauty instrument 001. Moreover, by providing the ventilation hole on the inclined tail cover part 131, when the ventilation hole is an air outlet, when the beauty instrument 001 is used, that is, when performing radio frequency beauty treatment on the face, the air can be blown obliquely downward to dissipate heat, thereby preventing the hot air from blowing on the user and other people nearby.

[0160] Further, the outer wall surface of the first front shell region 13021 of the second front shell assembly part 1302 is not coplanar with the outer wall surface of the front shell 130, so that a third step is formed between the first front shell region 13021 of the second front shell assembly part 1302 and the outer wall of the front shell 130. When the rear shell 120 is connected to the front shell 130, the rear shell 120 is attached to the bottom wall of the third step, and one end of the rear shell 120 close to the front shell 130 abuts against the side wall of the third step. The bottom wall of the third step, that is, the first front shell region 13021 of the second front shell assembly part 1302 is away from the outer periphery of the accommodating cavity 100a. The rear shell 120 abuts against the side wall of the third step, which can limit the movement of the rear shell 120 relative to the front shell 130 along the second direction Y.

[0161] Optionally, the second front shell assembly part 1302 is provided with a second front shell engaging member 13023 in the first front shell region 13021, and the second rear shell assembly part 1202 is provided with a second rear shell engaging member 12023 in the fourth rear shell region 12021. The second front shell assembly part 1302 is provided with a third front shell engaging member 13024 in the second front shell region 13022, and the second rear shell assembly part 1202 is provided with a third rear shell engaging member 12024 in the fifth rear shell region 12022. The second front shell engaging member 13023 is engaged with the second rear shell engaging member 12023, so that the first front shell region 13021 and the fourth rear shell region 12021 are relatively fixedly connected along the second direction Y. The third front shell engaging member 13024 is engaged with the third rear shell engaging member 12024 , so that the second front shell region 13022 and the fifth rear shell region 12022 are relatively fixedly connected along the first direction X.

[0162] Optionally, the second front shell engaging member 13023 is a locking hole, and the second rear shell engaging member 12023 is a buckle. The buckle can be elastically deformed to enter the locking hole, and after the buckle is locked into the locking hole, the buckle elastically restores its shape to achieve the locking of the buckle and the locking hole.

[0163] Optionally, the second rear shell engaging member 12023 is a locking hole, and the third front shell engaging member 13024 is a buckle. The buckle can be elastically deformed to enter the locking hole, and after the buckle is locked into the locking hole, the buckle elastically restores its shape to achieve the locking of the buckle and the locking hole.

[0164] In the present application, when assembling the head shell 110, the rear shell 120 and the front shell 130, the head shell 110 and the front shell 130 can be assembled first. The first front shell snap-fitting piece 13011 of the front shell 130 snaps into place with the second head shell snap-fitting piece 11321 of the head shell 110. The first front shell area 13021 of the front shell 130 and the second head shell assembly part 1132 of the head shell 110 are connected, and the first front shell area 13021 and the second head shell assembly part 1132 are in an arc-shaped transition. An opening is formed between the tail cover part 131 and the head shell 110. The first accommodating groove 120a of the rear shell 120 is directed toward the front shell 130, and the rear shell 120 is driven to enter the opening formed between the tail cover part 131 and the head shell 110. The first rear shell assembly part 1201 of the rear shell 120 is connected to the first head shell assembly part 1131 of the head shell 110, and the second rear shell assembly part 1202 of the rear shell 120 is connected to the second front shell assembly part 1302 of the front shell 130. The head shell 110 and the front shell 130 are both connected to the rear shell 120. The head shell 110 further fixes the relative positions of the front shell 130 and the head shell 110, so that the head shell 110, the front shell 130 and the rear shell 120 are relatively fixedly connected to form the accommodating cavity 100a.

[0165] Optionally, the second front shell assembly part 1302 is provided with a second front shell fitting in the first front shell area 13021, and the second rear shell assembly part 1202 is provided with a second rear shell fitting in the fourth rear shell area 12021. The second front shell assembly part 1302 is provided with a third front shell fitting in the second front shell area 13022, and the second rear shell assembly part 1202 is provided with a third rear shell fitting in the fifth rear shell area 12022. The second front shell fitting fits tightly with the second rear shell fitting, so that the first front shell area 13021 and the fourth rear shell area 12021 are relatively fixedly connected along the second direction Y. The third front shell fitting fits with the third rear shell fitting, so that the second front shell area 13022 and the fifth rear shell area 12022 are relatively fixedly connected along the first direction X.

[0166] Optionally, the second front shell fitting piece is a magnetic piece, and the second rear shell fitting piece is a magnetic piece. The second front shell fitting piece and the second rear shell fitting piece can be magnetically matched. Optionally, the second front shell fitting piece is an adhesive piece, and the second rear shell fitting piece is an adhesive surface.

The third front shell fitting piece and the third rear shell fitting piece can be matched by magnetic attraction. Optionally, the third front shell fitting piece is an adhesive piece, and the third rear shell fitting piece is an adhesive surface. The third front shell fitting piece and the third rear shell fitting piece can be matched by adhesion.

[0168] Please refer to Figure 2 and Figure 4The control component includes a main control board 310, which is connected to the air source component 500 and is used to control the opening or closing of the air flow driving member, and / or to control the air path switching module 520 to switch between the negative pressure mode and the deflation mode.

[0169] Optionally, the main control board 310 is a part of the main body 010. The main control board 310 is disposed in the accommodating cavity 100a, and the main control board 310 can be connected to the RF electrode 420, the air pump 510, the button block 721, etc. In some embodiments, the main control board 310 is electrically connected to the first electrical connector 240, so as to be electrically connected to the RF electrode 420 through the first electrical connector 240 and the second electrical connector 470.

[0170] Optionally, the front shell 130 is provided with a first clamping groove 132. One side of the main control board 310 is clamped in the first clamping groove 132. The rear shell 120 is provided with a second clamping groove 122, and the side of the main control board 310 facing away from the front shell 130 is clamped in the second clamping groove 122. The first clamping groove 132 and the second clamping groove 122 can limit the relative position of the main control board 310 and the housing 100, so as to fix the main control board 310.

[0171] When the main control board 310 needs to be assembled with the accommodating cavity 100a, one side of the main control board 310 can be first clamped in the first clamping groove 132. The rear shell 120 is brought close to the front shell 130 along the second direction Y, and at this time, the main control board 310 is aligned with the second clamping groove 122. When the front shell 130 and the rear shell 120 are assembled, the side of the main control board 310 that is away from the front shell 130 is also clamped in the second clamping groove 122.

[0172] Figure 6 A schematic structural diagram of a connection module 200 and a head shell 110 of a beauty instrument 001 in one embodiment of the present application is shown. Figure 7 A schematic structural diagram of a connection module 200 of a beauty instrument 001 in one embodiment of the present application is shown.

[0173] Please refer to Figure 6 and Figure 7 The main body 010 also includes a connection module 200 (please refer to Figure 2 The connecting module 200 is connected to the head shell 110 and is exposed from the head shell 110 so as to be detachably connected to the beauty head 030.

[0174] The connection module 200 includes a connection inner shell 210 and a first electrical connector 240 ; the first electrical connector 240 is mounted on the connection inner shell 210 , and the connection inner shell 210 is mounted on the head shell 110 , so that the connection module 200 is mounted on the head shell 110 as a whole.

[0175] Please refer to Figure 6 and Figure 7The inner shell 210 includes an inner base plate 211 and an inner enclosure plate 212. The inner enclosure plate 212 is disposed on one side of the inner base plate 211, and the inner enclosure plate 212 and the inner base plate 211 are combined to form an assembly groove 212a, and the inner base plate 211 forms the bottom of the assembly groove 212a. The head shell 110 has an opening, and the assembly groove 212a is exposed from the opening of the head shell 110.

[0176] When the beauty instrument 001 is used, the opening of the head shell 110 faces the user's skin (such as facial skin). The bottom wall of the assembly groove 212a forms a first assembly surface 212b. The first assembly surface 212b is used to match the second assembly surface 412a of the beauty head 030. The assembly groove 212a connected to the inner shell 210 is used for the beauty head 030 to be installed, so as to improve the installation stability of the beauty head 030.

[0177] The head shell 110 is provided with an inwardly turned inner edge 114 at the opening, and the inner edge 114 is formed on the above base plate 110b, and one end of the inner panel 212 away from the inner base plate 211 abuts against the inner edge 114 of the head shell 110. The inner edge 114 of the head shell 110 limits the connection inner shell 210 from extending out of the head shell 110 along the first inclined direction U, and is used to hide the connection inner shell 210 to improve the waterproof performance.

[0178] When the beauty head 030 needs to be installed in the assembly groove 212a, the beauty head 030 first passes through the opening of the head shell 110 and then is installed in the assembly groove 212a. It can be understood that the head shell 110 can also be integrally formed with the connecting inner shell 210, so that the head shell 110 and the connecting inner shell 210 are relatively fixed and the assembly steps are reduced.

[0179] The head shell 110 also has a stop member 115. The stop member 115 is used to limit the connection inner shell 210 from being away from the opening along the first inclined direction U. Optionally, the stop member 115 is a stop protrusion, and the stop protrusion protrudes from the enclosure body 111 in the installation cavity 110a, that is, the stop protrusion is arranged on the inner side of the enclosure body 111. When the connection inner shell 210 is arranged in the installation cavity 110a of the head shell 110, the stop protrusion is located on the side of the inner base plate 211 away from the opening of the head shell 110, and the inner base plate 211 is abutted by the stop protrusion. The inner enclosure 212 is contacted or abutted by the inner flange 114, and the inner base plate 211 is abutted by the stop protrusion, so that the position of the connection inner shell 210 relative to the head shell 110 along the first inclined direction U is limited. When the beauty head 030 is inserted into the connecting inner shell 210 and a force is applied to the connecting inner shell 210 , the connecting inner shell 210 is not easy to move along the first inclined direction U relative to the head shell 110 .

[0180] Specifically, the inner contour of the mounting cavity 110a is non-circular, and the outer contour of the connecting inner shell 210 is also non-circular, so that when the connecting inner shell 210 is arranged in the head shell 110, the connecting inner shell 210 is not easy to rotate relative to the head shell 110 around the axis of the first tilt direction U.

[0181] Optionally, the inner contour of the mounting cavity 110a is roughly square, and the outer contour of the connecting inner shell 210 is roughly square, so that when the connecting inner shell 210 is disposed in the head shell 110, the connecting inner shell 210 is not easy to rotate relative to the head shell 110 around the axis of the first tilt direction U.

[0182] Specifically, the inner contour of the assembly groove 212a is non-circular, and the outer contour of the portion of the beauty head 030 inserted into the assembly groove 212a is also non-circular, so that when the portion of the beauty head 030 inserted into the assembly groove 212a is disposed in the head shell 110, the portion of the beauty head 030 inserted into the assembly groove 212a is not easy to rotate relative to the head shell 110 around the axis of the first tilting direction U. Optionally, the inner contour of the assembly groove 212a is substantially square, and the outer contour of the portion of the beauty head 030 inserted into the assembly groove 212a is substantially square, so that when the portion of the beauty head 030 inserted into the assembly groove 212a is disposed in the head shell 110, the portion of the beauty head 030 inserted into the assembly groove 212a is not easy to rotate relative to the head shell 110 around the axis of the first tilting direction U.

[0183] In some embodiments, the connection module 200 further includes a locking structure 220. The locking structure 220 includes a locking assembly 221.

[0184] Specifically, the locking assembly 221 is used to connect the beauty head 030 when the first assembly surface 212b contacts or abuts the second assembly surface 412a, so as to limit the beauty head 030 from being away from the connection module 200 and the main body 010. In this way, the beauty head 030 can be connected to the main body 010 by setting the locking assembly 221.

[0185] In one embodiment, optionally, the locking assembly 221 is used to engage with the beauty head 030 when the first assembly surface 212b contacts or abuts the second assembly surface 412a to limit the beauty head 030 from being away from the connection module 200. In this way, the beauty head 030 and the main body 010 can be limited by engaging, which is convenient for disassembly and assembly.

[0186] Among them, the locking component 221 includes a snap-fitting portion, and the beauty head 030 is provided with a snap-fitting portion 4123; the snap-fitting portion is provided on the first assembly surface 212b, and the snap-fitting portion 4123 is provided on the second assembly surface 412a; when the first assembly surface 212b contacts or abuts against the second assembly surface 412a, the snap-fitting portion cooperates with the snap-fitting portion 4123 and limits the relative position of the beauty head 030 and the main body 010.

[0187] Furthermore, the connection module 200 further includes an unlocking component 222, and the unlocking component 222 is used to release the cooperation between the locking component 221 and the beauty head 030. In this way, disassembly and assembly can be achieved.

[0188] Specifically, the unlocking assembly 222 acts on the locking assembly 221; the unlocking assembly 222 is configured such that when the unlocking assembly 222 is pressed, the unlocking assembly 222 drives the engaging portion and / or the engaging portion 4123 to slide, so as to release the engagement between the locking assembly 221 and the engaging portion 4123. In this way, the association between the unlocking assembly 222 and the locking assembly 221 is improved, and the design is simplified.

[0189] In another embodiment, optionally, the locking assembly 221 is used to magnetically attract the beauty head 030 when the first assembly surface 212 b contacts or abuts the second assembly surface 412 a , so as to limit the beauty head 030 from being away from the connection module 200 .

[0190] In a specific embodiment, the locking assembly 221 is used to cooperate with the clamping portion 4123 of the beauty head 030 to limit the relative movement between the beauty head 030 and the connecting inner shell 210 (along the first inclined direction U, ie, the detachable direction).

[0191] In a specific embodiment, the locking structure 220 further includes an unlocking assembly 222. The unlocking assembly 222 is used to release the cooperation between the locking assembly 221 and the clamping portion 4123, so that the beauty head 030 can move relative to the inner shell 210 along the first inclined direction U, thereby removing the beauty head 030 from the assembly groove 212a along the first inclined direction U.

[0192] Specifically, the connection module 200 is provided with an assembly groove 212a, the first airflow connection part 232 is arranged at the bottom of the assembly groove 212a, the bottom of the assembly groove 212a forms a first assembly surface 212b, the beauty head 030 is installed in the assembly groove 212a, and the first assembly surface 212b contacts or abuts against the second assembly surface 412a.

[0193] Optionally, the connection module 200 may further include a pop-up member, and the pop-up member is used to drive the beauty head 030 away from the connection module 200 after the unlocking component 222 releases the cooperation between the locking component 221 and the beauty head 030 .

[0194] Specifically, the ejection member includes a first magnetic member and a second magnetic member, the first magnetic member is disposed on the connecting inner shell 210, and the second magnetic member is disposed on the mounting shell 410. The first magnetic member and the second magnetic member repel each other, so that the beauty head 030 has a tendency to move away from the connecting module 200. It can be understood that the ejection member can also be a spring, which is disposed on the connecting inner shell 210 or the mounting shell 410. When the mounting shell 410 is installed in the assembly groove 212a, the spring is compressed so that the spring stores elastic potential energy.

[0195] It can be understood that the locking assembly 221 may also include a first magnetic locking member and a second magnetic locking member. The first magnetic locking member is provided on the main body 010, and the second magnetic locking member is provided on the beauty head 030. When the beauty head 030 approaches the main body 010, the main body 010 magnetically attracts the beauty head 030 through the magnetic attraction of the first magnetic locking member and the second magnetic locking member, so as to restrict the beauty head 030 from being away from the main body 010.

[0196] Figure 8 A structural schematic diagram of the connection module 200 from another perspective in one embodiment of the present application is shown.

[0197] Please refer to Figure 7 and Figure 8 In an exemplary embodiment, the locking assembly 221 may optionally include a movable stopper 2211 and a locking elastic member 2212, wherein the movable stopper 2211 has a clamping portion 4123. The movable stopper 2211 is slidably matched with the connecting inner shell 210, that is, the movable stopper 2211 is slidably mounted on the connecting inner shell 210, and the movable stopper 2211 has a locking position in which the clamping portion 4123 is clamped with the engaging portion through the buckling movable hole 2112, and an unlocking position in which the clamping portion 4123 is separable from the engaging portion, so that the beauty head 030 can be installed by moving the movable stopper 2211.

[0198] Specifically, the movable stopper 2211 is slidably arranged on the inner side of the bottom of the assembly groove 212a, the bottom of the assembly groove 212a is provided with a buckling movable hole 2112, the movable stopper 2211 has a clamping portion arranged at the buckling movable hole 2112, the second assembly surface 412a is provided with a clamping portion 4123, and the movable stopper 2211 has a locking position in which the clamping portion 4123 is engaged with the clamping portion through the buckling movable hole 2112, and an unlocking position in which the clamping portion 4123 is separable from the clamping portion. In this way, the present application utilizes the large space on the inner side of the bottom of the assembly groove 212a to facilitate the arrangement of the movable stopper 2211, and can provide a movement space for the movable stopper 2211, which can simplify the design. Moreover, by driving the movable stopper 2211 to move, the beauty head 030 and the main body 010 can be locked or unlocked.

[0199] Specifically, a side of the inner base plate 211 facing away from the inner enclosure plate 212 forms a sliding surface 2111. Optionally, the sliding surface 2111 is perpendicular to the first tilting direction U. The movable stopper 2211 can slide along the sliding surface 2111, thereby moving relative to the beauty head 030. It can be understood that the movable stopper 2211 can also be guided based on other components to guide the movement of the movable stopper 2211. For example, the movable stopper 2211 can also be guided based on a side of the inner base plate 211 close to the inner enclosure plate 212.

[0200] The movable stopper 2211 is provided with a snap-fitting portion. The snap-fitting portion is convexly arranged on the surface of the movable stopper 2211, and is movably arranged in the buckle movable hole 2112 in the sliding direction, so as to cooperate with the snap-fitting portion 4123. Optionally, the snap-fitting portion is used to slide along the sliding surface 2111 with the movable stopper 2211, and cooperate with the snap-fitting portion 4123, so that the movable stopper 2211 is snap-fitted with the beauty head 030.

[0201] Optionally, the engaging portion includes a hook 22111. The engaging portion 4123 includes a slot 41231. A buckle movable hole 2112 is provided on the inner base plate 211 connected to the inner shell 210, and the hook 22111 extends through the buckle movable hole 2112 to a side of the inner shell 210 where the assembly slot 212a is provided. Optionally, the buckle movable hole 2112 extends in one direction, that is, it has a certain length to avoid the hook 22111 and the engaging portion 4123, so that the hook 22111 extending into the buckle movable hole 2112 can move relative to the movable stopper 2211 along the sliding direction. The movable stopper 2211 slides along the sliding surface 2111, so that the hook 22111 can enter the slot 41231. When the hook 22111 enters the slot 41231, the hook 22111 acts on the inner wall of the slot 41231, thereby limiting the beauty head 030 from being separated from the inner shell 210 along the first inclined direction U. At this time, the beauty head 030 and the main body 010 are connected, which facilitates the coordination between the main body 010 and the beauty head 030, thereby realizing the connection between the negative pressure groove 4111 and the main body 010 for generating negative pressure, and the radio frequency electrode 420 is electrically connected to the main body 010 so that the main body 010 provides electrical energy to the radio frequency electrode 420.

[0202] Optionally, the movable stopper 2211 slides on the sliding surface 2111 along a sliding direction, that is, a second inclined direction V. The second inclined direction V is perpendicular to the first inclined direction U.

[0203] Furthermore, a guide member 213 is protrudingly provided on the inner side surface (ie, the sliding surface 2111 ) of the bottom of the assembly groove 212 a . The guide member 213 defines a sliding groove structure, and the movable limiting member 2211 is slidably disposed in the sliding groove structure.

[0204] Specifically, the guide member 213 is clamped on both sides of the movable stopper 2211 perpendicular to the second tilting direction V, thereby limiting the movable stopper 2211 from sliding relative to the connected inner shell 210 along the second tilting direction V and preventing it from being easily deflected. A barb 2131 is provided at one end of the guide member 213 away from the sliding surface 2111. The barb 2131 extends in the direction of the movable stopper 2211, and the barb 2131 acts on one end of the movable stopper 2211 away from the sliding surface 2111, so that the movable stopper 2211 is not easily separated from the sliding surface 2111 along the first tilting direction U.

[0205] Optionally, the guide member 213 is an elastic element, and the barb 2131 can be displaced relative to the sliding surface 2111 through the deformation of the guide member 213. When the guide members 213 on both sides of the movable stopper 2211 are deformed, the barbs 2131 on both sides of the movable stopper 2211 can be moved away from each other, which is convenient for assembling the movable stopper 2211 on the sliding surface 2111. As the movable stopper 2211 contacts the sliding surface 2111, the barb 2131 recovers its position through the deformation of the guide member 213 and is located at one end of the movable stopper 2211 away from the sliding surface 2111, thereby limiting the movable stopper 2211 from disengaging from the sliding surface 2111 along the first inclined direction U. It can be understood that the guide member 213 is an elastic element, so that the guide member 213 can be elastically deformed. As the guide member 213 is deformed, the deformation amount of the end of the guide member 213 away from the sliding surface 2111 is greater than the deformation amount of the end close to the sliding surface 2111. Therefore, the deformation of the guide member 213 enables the barb 2131 to generate sufficient displacement to facilitate the assembly of the movable stopper 2211 and the connection of the inner shell 210, and also enables the end of the guide member 213 close to the sliding surface 2111 to be almost free of deformation, and the guide member 213 can still limit the displacement of the movable stopper 2211 in a direction perpendicular to the second tilting direction V. The guide member 213 can be formed of an elastic material to form an elastic element.

[0206] Optionally, the locking elastic member 2212 is disposed at one end of the movable stopper 2211 along the second tilting direction V. One end of the locking elastic member 2212 abuts against the connecting inner shell 210, and the other end abuts against the movable stopper 2211. The locking elastic member 2212 can drive the movable stopper 2211 to slide relative to the connecting inner shell 210 along the second tilting direction V. The connecting inner shell 210 includes a resisting member 214 disposed on the sliding surface 2111. The resisting member 214 protrudes from the sliding surface 2111. The locking elastic member 2212 is disposed between the resisting member 214 and the movable stopper 2211. The locking elastic member 2212 can be a compression spring to drive the movable stopper 2211 away from the resisting member 214 along the second tilting direction V. A guiding inclined surface 22112 is disposed at the end of the hook 22111, and the guiding inclined surface 22112 is inclined to the sliding surface 2111. After the beauty head 030 is installed into the assembly groove 212a along the first tilt direction U and contacts the guide slope 22112, the beauty head 030 continues to approach the first assembly surface 212b along the tilt direction and acts on the guide slope 22112 of the hook 22111 to drive the hook 22111 to approach the abutment 214 along the second tilt direction V. At this time, the movable limiter 2211 and the abutment 214 jointly compress the locking elastic member 2212. When the beauty head 030 continues to approach the first assembly surface 212b along the first tilt direction U, so that the hook 22111 is aligned with the slot 41231 of the beauty head 030, the locking elastic member 2212 restores its shape, so that the hook 22111 moves away from the abutment 214 along the second tilt direction V and enters the slot 41231, thereby achieving the locking of the beauty head 030 and the connecting inner shell 210 along the first tilt direction U.

[0207] Fig. 9 A schematic structural diagram of a connection module 200 of a beauty instrument 001 in one embodiment of the present application is shown, wherein an unlocking button 2221 is pressed to drive the movable limiting member 2211 to approach the supporting member 214 . Fig.10 A schematic structural diagram of a connection module 200 of a beauty instrument 001 in one embodiment of the present application is shown, wherein the unlocking button 2221 is not pressed, and the locking elastic member 2212 restores its shape to drive the movable limiting member 2211 away from the supporting member 214 .

[0208] See also Fig. 9 and Fig.10, optionally, the movable stopper 2211 is provided with a guide groove 22113. The locking elastic member 2212 extends into the guide groove 22113, and the inner wall of the guide groove 22113 can contact the locking elastic member 2212, thereby limiting the deformation of the locking elastic member 2212. When the movable stopper 2211 slides relative to the connecting inner shell 210 along the second inclined direction V, the movable stopper 2211 and the abutting member 214 jointly squeeze the locking elastic member 2212, and the inner wall of the guide groove 22113 can limit the deformation of the locking elastic member 2212 along the second inclined direction V as much as possible, so as to form an elastic force parallel to the second inclined direction V as much as possible. When the locking elastic member 2212 releases and restores its shape to drive the elastic member to slide relative to the connecting inner shell 210, the elastic force of the locking elastic member 2212 is as parallel to the second inclined direction V as possible, which can reduce the jamming of the movable stopper 2211 when sliding.

[0209] Fig.11 A structural schematic diagram of the connection module 200 from another perspective in one embodiment of the present application is shown. Fig.12 Shows Fig.11 A partial enlarged view of area B.

[0210] Please refer to Figure 7 , Fig.11 and Fig.12 The unlocking assembly 222 is used to drive the movable stopper 2211 to overcome the elastic force of the locking elastic member 2212 to approach the abutting member 214 along the second inclined direction V. In this process, the hook 22111 is disengaged from the slot 41231 along the second inclined direction V to release the lock of the beauty head 030 and the connecting inner shell 210 along the first inclined direction U.

[0211] Optionally, the unlocking assembly 222 includes an unlocking button 2221 and an unlocking elastic member 2222. One end of the unlocking button 2221 extends out of the housing 100, and the other end is inserted into the mounting cavity 110a to drive the movable stopper 2211 to slide. One end of the unlocking elastic member 2222 acts on the unlocking button 2221, and the other end acts on the connecting inner housing 210. The unlocking elastic member 2222 applies an elastic force to the unlocking button 2221 away from the movable stopper 2211, so that the unlocking button 2221 has a movement tendency away from the movable stopper 2211. When the beauty head 030 needs to be removed from the connecting inner housing 210, the user can press the unlocking button 2221, and the unlocking button 2221 applies pressure to the movable stopper 2211 to overcome the locking elastic member 2212. The movable stopper 2211 approaches the abutting member 214 along the second inclined direction V, and the hook 22111 gradually disengages from the slot 41231. When the hook 22111 is disengaged from the slot 41231 , the locking of the beauty head 030 and the connecting inner shell 210 along the first tilting direction U is released, and the user can remove the beauty head 030 from the connecting inner shell 210 .

[0212] Optionally, the head shell 110 is provided with a button hole 1101, and the unlocking button 2221 extends out of the head shell 110 through the button hole 1101, so that the user can press the unlocking button 2221. The inner wall of the installation cavity 110a forms a guide arc surface 1103 on the side where the button hole 1101 is provided. When the connection inner shell 210 and the locking structure 220 in the connection module 200 are assembled together into the installation cavity 110a, the guide arc surface 1103 abuts against the unlocking button 2221 until the unlocking button 2221 is aligned with the button hole 1101 and extends out of the button hole 1101.

[0213] Optionally, the unlocking assembly 222 further includes a transmission member 2223. The unlocking button 2221 acts on the movable stopper 2211 through the transmission member 2223 to drive the movable stopper 2211 to move along the second tilting direction V. The transmission member 2223 is movably connected to the connecting inner shell 210, and under the drive of the unlocking button 2221 or the movable stopper 2211, the transmission member 2223 moves relative to the connecting inner shell 210. The connecting inner shell 210 is provided with a positioning shaft 2113 on the sliding surface 2111. The transmission member 2223 has a first transmission end 22231 and a second transmission end 22232 that are opposite to each other. The first transmission end 22231 of the transmission member 2223 is sleeved on the positioning shaft 2113, and can rotate around the positioning shaft 2113 relative to the connecting inner shell 210. The second transmission end 22232 of the transmission member 2223 can abut against the movable stopper 2211 to push the movable stopper 2211 close to the abutting member 214. The unlocking button 2221 has a push rod 22211, and the push rod 22211 is arranged toward the transmission member 2223. When the user presses the unlocking button 2221, the push rod 22211 of the unlocking button 2221 can push the transmission member 2223 to rotate, and the transmission member 2223 pushes the movable stopper 2211 close to the abutting member 214. The push rod 22211 acts on the area of ​​the transmission member 2223 between the first transmission end 22231 and the second transmission end 22232, so that the transmission member 2223 forms a lever, and the displacement of the push rod 22211 along the second tilting direction V is amplified by the transmission member 2223 and then acts on the movable stopper 2211.

[0214] Optionally, the movable stopper 2211 includes an arc transmission surface 22114. The second transmission end 22232 of the transmission member 2223 is slidably matched with the arc transmission surface 22114. When the transmission member 2223 rotates around the positioning shaft 2113, the second transmission end 22232 of the transmission member 2223 acts on the arc transmission surface 22114 and pushes the movable stopper 2211 to slide. The arc motion path of the second transmission end 22232 and the linear motion path of the movable stopper 2211 are matched through the relative sliding of the second transmission end 22232 and the arc transmission surface 22114. The arc transmission surface 22114 allows the second transmission end 22232 and the movable stopper 2211 to slide relative to each other smoothly, and the user has a better sense of pressing the unlock button 2221 to drive the movable stopper 2211 to move.

[0215] Optionally, the transmission member 2223 includes a plurality of centering arms 22233. The transmission member 2223 has a transmission hole. The positioning shaft 2113 passes through the transmission hole, so that the plurality of centering arms 22233 abut against the positioning shaft 2113, so that the transmission member 2223 is rotatably connected relative to the inner shell 210 around the positioning shaft 2113. The plurality of centering arms 22233 are circumferentially arranged in the transmission hole, and the centering arms 22233 extend from the inner wall of the transmission hole to the axis of the transmission hole. When the positioning shaft 2113 passes through the transmission hole, the plurality of centering arms 22233 are circumferentially arranged on the outer periphery of the positioning shaft 2113, and each centering arm 22233 abuts against the positioning shaft 2113. Each centering arm 22233 is inclined to the radial arrangement of the transmission hole, that is, the centering arm 22233 is inclined to the radial arrangement of the positioning shaft 2113. Each centering arm 22233 has a contact arc surface 222331, and the contact arc surface 222331 is used to abut the positioning shaft 2113. The contact arc surface 222331 can increase the contact area between the centering arm 22233 and the positioning shaft 2113, and improve the stability of the transmission member 2223 and the positioning shaft 2113 when they are matched. The centering arm 22233 can elastically abut the positioning shaft 2113, and the centering arm 22233 applies an elastic force to the positioning shaft 2113. This allows the transmission member 2223 to elastically return to its original position after eccentrically moving the positioning shaft 2113.

[0216] Optionally, each centering arm 22233 includes a first arm segment 222332 and a second arm segment 222333. The first arm segment 222332 extends from the inner wall of the transmission hole approximately along the radial direction of the transmission hole. The second arm segment 222333 extends from one end of the first arm segment 222332 away from the inner wall of the transmission hole approximately along the circumferential direction of the transmission hole. A deformation groove can be formed between the second arm segment 222333, the first arm segment 222332 and the inner wall of the transmission hole. When the second arm segment 222333 is squeezed, it can be deformed in the direction of the deformation groove. An abutting arc surface 222331 is provided at one end of the second arm segment 222333 away from the first arm segment 222332, and the second arm segment 222333 abuts against the positioning shaft 2113 through the abutting arc surface 222331.

[0217] Optionally, there are three centering arms 22233. The three centering arms 22233 are evenly arranged around the axis of the transmission hole.

[0218] Optionally, the transmission member 2223 further includes a limiting protrusion 22234. The limiting protrusion 22234 is located between the first transmission end 22231 and the second transmission end 22232. The push rod 22211 of the unlocking button 2221 acts on the side of the limiting protrusion 22234 facing the first transmission end 22231. The side of the limiting protrusion 22234 facing the first transmission end 22231 has a guide arc surface 22235. When the push rod 22211 pushes the transmission member 2223 to rotate around the positioning shaft 2113, the push rod 22211 slides along the guide arc surface 22235. The linear motion of the push rod 22211 pushes the transmission member 2223 to rotate around the positioning shaft 2113 smoothly.

[0219] Optionally, one end of the unlocking elastic member 2222 is connected to the unlocking button 2221, and the other end is connected to the fixing column 217. When the user presses the unlocking button 2221, the unlocking button 2221 presses the unlocking elastic member 2222 toward the fixing column 217, so that the unlocking elastic member 2222 is deformed and stores elastic potential energy. When the user no longer presses the unlocking button 2221, the unlocking elastic member 2222 can release the elastic potential energy and drive the unlocking button 2221 away from the fixing column 217 to return to the position before pressing.

[0220] The unlocking elastic member 2222 includes an elastic arm 22221 and a limiting clip 22222. One end of the elastic arm 22221 is connected to the unlocking button 2221, and the other end is connected to the limiting clip 22222. The limiting clip 22222 is held against the fixed column 217. The limiting clip 22222 can also rotate around the fixed column 217. The elastic arm 22221 includes a first section 22223 and a second section 22224. The first section 22223 extends from the unlocking button 2221 to a side of the fixed column 217 away from the unlocking button 2221, and the second section 22224 extends from the end of the first section 22223 to the fixed column 217. The second section 22224 is arc-shaped, so that when the elastic arm 22221 is deformed, the stress concentration at each position of the elastic arm 22221 is reduced, thereby increasing the service life of the elastic arm 22221. The elastic arm 22221 makes the limiting clip 22222 have a tendency to move toward the push rod 22211. When the limiting clip 22222 abuts against the side of the fixed column 217 away from the push rod 22211, the elastic arm 22221 can make the limiting clip 22222 apply elastic force to the fixed column 217, thereby improving the stability of the connection between the limiting clip 22222 and the fixed column 217. The limiting clip 22222 is roughly in the shape of a semicircular ring, and the end of the limiting clip 22222 close to the unlocking button 2221 also has a straight extension section 22225. When the unlocking button 2221 drives the unlocking elastic member 2222 to deform and move, the limiting clip 22222 rotates around the fixed column 217, and the end of the limiting clip 22222 close to the unlocking button 2221 applies a large pressure to the fixed column 217, and the end of the limiting clip 22222 close to the unlocking button 2221 has a risk of deformation. The straight extension section 22225 can further reduce the risk of the limiting clip 22222 being deformed and separated from the fixing column 217 .

[0221] Optionally, there are two unlocking elastic members 2222. The two unlocking elastic members 2222 are symmetrically arranged on both sides of the unlocking button 2221. The elastic arm 22221 of each unlocking elastic member 2222 makes the limiting clip 22222 have a tendency to move toward the other unlocking elastic member 2222.

[0222] Fig.13 A partial cross-sectional view of a beauty instrument 001 in one embodiment of the present application is shown.

[0223] Please refer to Figure 7 , Figure 8 and Fig.13 Optionally, the connection module 200 further includes an airflow connector 230. The airflow connector 230 includes a fixed base 231 and the first airflow connector 232. The first airflow connector 232 is a tubular airflow connector. The fixed base 231 is fixedly connected to the first airflow connector 232. The first airflow connector 232 is provided with a first airway hole 232a.

[0224] Please refer to Figure 7 , Figure 8 and Fig.13 , optionally, the fixed base 231 is connected to the connecting inner shell 210 .

[0225] The connecting inner shell 210 is provided with a plurality of connecting columns 215, and the connecting columns 215 are provided with threaded holes. The fixing base 231 has a plurality of connecting through holes. Bolts are passed through the connecting through holes and threadedly matched with the threaded holes of the connecting columns 215, so that the fixing base 231 and the connecting inner shell 210 can be relatively fixed, and then the first airflow connecting portion 232 and the connecting inner shell 210 can be relatively fixed.

[0226] Optionally, the three connecting columns 215 are located at the three vertices of the triangle. The three connecting columns 215 can be located at the three vertices of a triangle (such as an isosceles triangle) to provide relatively uniform support force. The fixed base 231 is roughly triangular. The fixed base 231 is provided with a connecting through hole at each corner of the triangle to correspond to each connecting column 215. The fixed base 231 and the connecting inner shell 210 are connected by three bolts to improve the stability of the connection between the fixed base 231 and the connecting inner shell 210. The first airflow connection part 232 is located between the three connecting through holes on the fixed base 231. When the first airflow connection part 232 is subjected to external force, the external force can be transmitted to the bolts corresponding to the three connecting through holes through the fixed base 231 in a roughly uniform manner. Each bolt restricts the movement of the airflow connector 230 relative to the connecting inner shell 210, so that the relative position relationship between the airflow connector 230 and the connecting inner shell 210 can be kept stable.

[0227] Optionally, the airflow connection member 230 further includes a reinforcing rib 233 , and the reinforcing rib 233 connects the fixed base 231 and the first airflow connection portion 232 to improve the stability of the first airflow connection portion 232 .

[0228] Optionally, the connecting inner shell 210 is provided with an airflow connection hole 2101, and the first airflow connection part 232 is an airflow connection tube, which is exposed from the first assembly surface 212b to the main body 010 through the airflow connection hole 2101, and further extends into the assembly groove 212a, so that the first airway hole 232a extends into the assembly groove 212a. When the beauty head 030 is installed in the assembly groove 212a, it is connected with the part of the first airflow connection part 232 extending into the assembly groove 212a, so that the beauty head 030 and the main body 010 are connected in airflow. Optionally, the first airflow connection part 232 extends along the first inclined direction U.

[0229] Optionally, the airflow connector 230 further includes a sealing ring 234. The sealing ring 234 is sleeved on the outer periphery of the first airflow connector 232. When the first airflow connector 232 is connected to the beauty head 030, the sealing ring 234 can fill the gap between the beauty head 030 and the outer periphery of the first airflow connector 232 to improve air tightness, thereby ensuring or improving the air extraction efficiency.

[0230] Optionally, there are two sealing rings 234 , and the two sealing rings 234 are arranged at intervals along the extension direction of the first airflow connection portion 232 , thereby enhancing the sealing effect.

[0231] Specifically, the sealing ring 234 is sleeved on the portion of the first airflow connection part 232 located in the assembly groove 212a. Optionally, the portion of the first airflow connection part 232 located in the assembly groove 212a is provided with two annular grooves 2321. The sealing ring 234 is partially accommodated in the annular groove 2321 and protrudes from the annular groove 2321 to fill the gap between the beauty head 030 and the outer periphery of the first airflow connection part 232.

[0232] Optionally, the movable stopper 2211 is provided with a clearance hole 2211a. Along the sliding direction, the size of the clearance hole 2211a is larger than the size of the first airflow connection part 232. The first airflow connection part 232 extends into the assembly groove 212a after passing through the clearance hole 2211a and the airflow connection hole 2101. As the movable stopper 2211 slides along the second inclined direction V, the clearance hole 2211a also moves along the second inclined direction V. Along the second inclined direction V, the size of the clearance hole 2211a is larger than the size of the first airflow connection part 232, which can prevent the movable stopper 2211 from touching the first airflow connection part 232 when sliding.

[0233] Optionally, the connecting inner shell 210 also has an exhaust port 216. The exhaust port 216 corresponds to the give way hole 2211a. When the beauty head 030 and the connecting inner shell 210 are assembled, an exhaust channel is formed between the beauty head 030 and the connecting inner shell 210, and the exhaust channel is connected to the exhaust port 216. Specifically, an exhaust channel is formed between the second assembly surface 412a and the first assembly surface 212b, and the exhaust channel is connected to the airflow driving member to exhaust the gas driven by the airflow driving member. When the beauty instrument 001 is exhausting, the gas can be exhausted through the path from the exhaust port 216 to the exhaust channel. In this way, by setting the exhaust port 216 in the connecting inner shell 210, the end of the airflow driving member having the inlet and outlet can be arranged toward the beauty head 030, so that the air path design can be simplified.

[0234] Optionally, the exhaust port 216 protrudes from the sliding surface 2111 to facilitate connection of the exhaust pipe. Along the second inclined direction V, the size of the clearance hole 2211a is larger than the combined size of the first airflow connection part 232 and the exhaust port 216, which can prevent the movable stopper 2211 from touching the first airflow connection part 232 or the exhaust port 216 when sliding. An exhaust gap 212c is formed between the outer periphery of the beauty head 030 and the side wall of the assembly groove 212a, and the exhaust gap 212c is connected to the exhaust channel, so that the gas can flow through the exhaust channel to the exhaust gap 212c, and then be discharged from the beauty instrument 001 through the exhaust gap 212c.

[0235] It can be understood that the exhaust gap 212c can be formed by setting a groove on the outer periphery of the mounting shell 410 of the beauty head 030, so that after the beauty head 030 is installed in the assembly groove 212a, the inner wall of the assembly groove 212a and the groove on the outer periphery of the mounting shell 410 form the exhaust gap 212c, and the exhaust gap 212c is connected to the exhaust channel, so that gas can be discharged from the beauty instrument 001. The exhaust gap 212c can also be formed by setting a groove on the inner wall of the assembly groove 212a, so that after the beauty head 030 is installed in the assembly groove 212a, the groove on the inner wall of the assembly groove 212a and the outer periphery of the mounting shell 410 form the exhaust gap 212c, and the exhaust gap 212c is connected to the exhaust channel, so that gas can be discharged from the beauty instrument 001. The exhaust gap 212c is formed between the beauty head 030 and the assembly groove 212a, so that when the beauty head 030 and the main body 010 are disassembled, the exhaust gap 212c can be cleaned by cleaning the outer periphery of the beauty head 030 and the inner wall of the assembly groove 212a.

[0236] Optionally, the exhaust port 216 includes a first hole segment 2161 and a second hole segment 2162 arranged in sequence. The first hole segment 2161 and the second hole segment 2162 are continuous and connected along the first inclined direction U. One end of the first hole segment 2161 away from the second hole segment 2162 is exposed from the first assembly surface 212b. In a cross section perpendicular to the extension direction of the exhaust port 216, that is, perpendicular to the first inclined direction U, the cross-sectional area of ​​the first hole segment 2161 is greater than the cross-sectional area of ​​the second hole segment 2162. The first hole segment 2161 has a larger cross-sectional area to facilitate connection with the air guide 4124 of the beauty head 030. The second hole segment 2162 has a smaller cross-sectional area so as to be exposed in the accommodating cavity 100a to connect the pipeline and then connect with the air flow driving member.

[0237] It is understandable that the exhaust port 216 may not be divided into the first hole segment 2161 and the second hole segment 2162 , so that the exhaust port 216 is cylindrical, flared or other shapes as a whole, and the exhaust port 216 can also be connected to the airflow driving member and the air guide member 4124 .

[0238] It is understandable that the location of the exhaust port 216 is not limited to being connected to the inner shell 210, that is, the main body 010 is provided with an exhaust port 216 for exhaust, such as being provided at the tail.

[0239] It is understandable that if the main body 010 is not provided with the exhaust port 216, exhaust can also be performed through the assembly gap of the main body 010, for example, through the assembly gap between the first half shell and the second half shell.

[0240] Fig.14 A schematic structural diagram of a head shell 110 and a connection module 200 in one embodiment of the present application is shown, wherein the connection module 200 includes a main circuit board 250 .

[0241] Please refer to Figure 7 and Fig.14 , optionally, the connection module 200 further includes a first electrical connector 240 and a main circuit board 250. The main circuit board 250 and the connection inner shell 210 are spaced apart along the first tilt direction U. The connection inner shell 210 is provided with a fixing column 217, and the fixing column 217 extends from the sliding surface 2111 along the first tilt direction U. The fixing column 217 is provided with a threaded hole. A fixing through hole 251 is provided at a position corresponding to the fixing column 217 on the main circuit board 250. By passing a bolt through the fixing through hole 251 and being threadedly connected with the fixing column 217, the relative position of the main circuit board 250 and the connection inner shell 210 can be kept fixed. There are multiple fixing columns 217, and correspondingly, multiple fixing through holes 251 are provided on the main circuit board 250. By connecting the main circuit board 250 and the fixing column 217 by multiple bolts, the stability of the connection between the main circuit board 250 and the connection inner shell 210 can be improved, and the main circuit board 250 can be prevented from rotating around any fixing column 217 relative to the connection inner shell 210. The main circuit board 250 is electrically connected to the main control board 310. The main circuit board 250 and the main control board 310 can be electrically connected through a flexible wire. The flexible wire is arranged in the accommodating cavity 100a and is protected by the housing 100. When the user uses the beauty instrument 001, it is not easy for the flexible wire to be displaced by external force, and the electrical connection between the main circuit board 250 and the main control board 310 can be maintained.

[0242] It is understandable that the first electrical connector 240 may also be an integrally formed conductor, such as the first electrical connector 240 being a metal rod.

[0243] The connecting inner shell 210 is also provided with an electrical connection hole 218. One end of the first electrical connector 240 is connected to the main circuit board 250, and the other end passes through the electrical connection hole 218 and is exposed from the first assembly surface 212b to the main body 010, and further extends into the assembly groove 212a. Figure 2When the beauty head 030 is installed in the assembly groove 212a, the beauty head 030 can contact the first electrical connector 240 installed in the assembly groove 212a. In this way, by providing the main body circuit board 250 to install the first electrical connector 240, it is convenient to install and fix the first electrical connector 240 so that the first electrical connector 240 is exposed from the main body 010.

[0244] Optionally, there are multiple first electrical connectors 240. When the beauty head 030 contacts multiple first electrical connectors 240, at least part of the first electrical connectors 240 are electrically connected to the beauty head 030, so that the beauty head 030 is electrically connected to the main body 010. The main body 010 can provide power to the beauty head 030 and control the operation of the beauty head 030.

[0245] Optionally, the number of the second electrical connectors 470 is set to be plural, so as to correspond one-to-one with the first electrical connectors 240 .

[0246] Optionally, the number of the first electrical connectors 240 is plural, for example, ten. The plurality of first electrical connectors 240 are divided into two groups, such as five first electrical connectors 240 in one group, and the two groups of first electrical connectors 240 are respectively located on both sides of the movable stopper 2211. The main circuit board 250 is provided with a through hole 252 between the two groups of first electrical connectors 240. The first airflow connection portion 232 and the exhaust port 216 are exposed from the through hole 252 to facilitate the assembly of the first airflow connection portion 232 and the exhaust port 216 with other airway components.

[0247] Optionally, the first electrical connector 240 and / or the second electrical connector 470 is a PIN, which can facilitate electrical connection with the beauty head 030.

[0248] For ease of distinction, in the subsequent content, the PIN pin configured as the first electrical connector 240 is referred to as the "electrical connection PIN pin", and the PIN pin corresponding to the second electrical connector 470 is referred to as the "electrical control PIN pin".

[0249] The first electrical connector 240 includes a fixed needle segment 241 and an elastic movable needle segment 242. The fixed needle segment 241 and the elastic movable needle segment 242 can be slidably elastically matched, so that the size of the first electrical connector 240 along the first tilting direction U can be adjusted. The fixed needle segment 241 is connected to the main circuit board 250, and the elastic movable needle segment 242 is installed in the assembly groove 212a through the electrical connection hole 218. When the beauty head 030 is installed in the assembly groove 212a and contacts the elastic movable needle segment 242, the elastic movable needle segment 242 can be squeezed to reduce the size of the first electrical connector 240 along the first tilting direction U. The error between the beauty head 030 and the main circuit board 250 is matched by the expansion and contraction amount of each first electrical connector 240 along the first tilting direction U, so that each first electrical connector 240 can be stably connected to the beauty head 030 as much as possible.

[0250] It can be understood that the end of the elastic movable needle segment 242 facing away from the fixed needle segment 241 forms a first electrical contact, and the first electrical contact is used to cooperate with the beauty head 030 to achieve electrical connection with the beauty head 030.

[0251] Fig.15 A schematic structural diagram of a beauty head 030 in one embodiment of the present application is shown. Fig.16 A schematic structural diagram of a shell 411 of a beauty head 030 in one embodiment of the present application is shown.

[0252] Please refer to Fig.15 and Fig.16 The beauty head 030 includes a mounting shell 410. The mounting shell 410 has a negative pressure end 410a and a connection end 410b opposite to each other. The mounting shell 410 is provided with a negative pressure groove 4111 at the negative pressure end 410a. The connection end 410b of the mounting shell 410 is used to be installed in the assembly groove 212a to connect the main body 010. The mounting shell 410 is also provided with a second airflow connection part 4114 connected to the negative pressure groove 4111. The mounting shell 410 is used to be detachably connected to the main body 010.

[0253] Furthermore, the negative pressure groove 4111 and the second assembly surface 412 a are respectively located on two opposite sides of the mounting shell 410 .

[0254] Furthermore, the mounting shell 410 includes a shell 411 and a cover 412. The shell 411 forms an accommodating cavity 4112 with an opening at the connecting end 410b, and the cover 412 is installed at the opening; optionally, the cover 412 and the shell 411 are connected to cover the opening of the accommodating cavity 4112. The side of the cover 412 facing away from the shell 411 forms a second assembly surface 412a.

[0255] The second assembly surface 412 a is disposed on the outer side of the cover body 412 , and the second electrical connector 470 is installed on the cover body 412 and exposed from the cover body 412 .

[0256] The second airflow connection portion 4114 extends from the negative pressure substrate 41101 toward the cover body 412 and is exposed from the cover body 412 .

[0257] It is understandable that for the beauty device 001 having the negative pressure tank 4111 to absorb the skin with negative pressure, after the beauty device 001 is finished working, the negative pressure tank 4111 is more likely to absorb dirt. By making the beauty head 030 detachably connected to the main body 010, the beauty head 030 can be removed and only the beauty head 030 can be cleaned, so that the negative pressure tank 4111 can be cleaned more conveniently.

[0258] Further, the housing 411 includes a negative pressure substrate 41101, a negative pressure enclosure 41102 and a receiving enclosure 41103. The negative pressure enclosure 41102 is disposed on one side of the negative pressure substrate 41101, and the negative pressure enclosure 41102 is convexly disposed on the negative pressure substrate 41101, so that the negative pressure enclosure 41102 and the negative pressure substrate 41101 jointly form a negative pressure groove 4111, and the RF electrode 420 is disposed on the negative pressure enclosure 41102 and / or the negative pressure substrate 41101.

[0259] The receiving enclosure 41103 is arranged on the side of the negative pressure substrate 41101 away from the negative pressure enclosure 41102, and the receiving enclosure 41103 is convexly arranged on the negative pressure substrate 41101, so that the negative pressure substrate 41101 and the receiving enclosure 41103 together form an open receiving cavity 4112, and the cover 412 is installed at the open part of the receiving cavity 4112, and the receiving cavity 4112 can receive the head circuit board 460. In this way, the housing 411 can be produced by integral injection molding to simplify assembly.

[0260] Furthermore, the size of the containing enclosure 41103 is larger than that of the negative pressure enclosure 41102. For example, along the projection plane perpendicular to the negative pressure substrate 41101, the projection of the negative pressure enclosure 41102 is located within the projection of the containing enclosure 41103, and the projection of the negative pressure groove 4111 is located within the projection of the containing cavity 4112. When the containing enclosure 41103 is installed in the assembly groove 212a, it can be installed in the assembly groove 212a more stably. Moreover, the negative pressure groove 4111 has a relatively small coverage area, thereby improving the adsorption and release efficiency of the negative pressure groove 4111, and can quickly generate negative pressure to adsorb the skin, and can also quickly inflate the negative pressure groove 4111 to release the adsorption of the skin.

[0261] Furthermore, the housing 411 is further provided with a first matching column 4113 in the accommodating cavity 4112, and the cover 412 is provided with a first matching hole 4121. The housing 411 and the cover 412 can be connected by a bolt passing through the first matching hole 4121 and threadedly engaging with the first matching column 4113. The first matching hole 4121 can be a countersunk hole to accommodate the bolt head of the bolt, so as to keep the side of the cover 412 facing away from the housing 411 substantially flat.

[0262] Further, the housing 411 has a second airflow connection portion 4114, and the cover 412 is provided with a negative pressure hole 4122. Optionally, the second airflow connection portion 4114 is a negative pressure pipe provided on the negative pressure substrate 41101. Optionally, the second airflow connection portion 4114 extends from the bottom of the negative pressure groove 4111 toward the cover 412, and is connected to the negative pressure hole 4122 to be exposed from the second assembly surface 412a.

[0263] The negative pressure duct has a second airway hole 411a. The second airflow connection part 4114 is used to be detachably connected to the first airflow connection part 232, so that the first airflow connection part 232 is connected to the second airflow connection part 4114. The docking direction of the first airflow connection part 232 and the second airflow connection part 4114 can match the matching direction of the beauty head 030 and the main body 010, that is, the first airflow connection part 232 and the second airflow connection part 4114 are docked in the disassembly direction, so that when the beauty head 030 is connected to the main body 010, the first airflow connection part 232 is connected to the second airflow connection part 4114. Optionally, when the beauty head 030 is installed in the assembly groove 212a, the first airflow connection part 232 in the assembly groove 212a is inserted into the second airflow connection part 4114 through the negative pressure hole 4122 and is connected to the second airflow connection part 4114. That is, the first airflow connection part 232 is disposed at the bottom of the assembly groove 212a and protrudes from the first assembly surface 212b to be inserted into the second airflow connection part 4114 to communicate with the second airflow connection part 4114. When the first airflow connection part 232 draws air, the air in the negative pressure groove 4111 can be drawn away by the first airflow connection part 232 through the second airflow connection part 4114, thereby forming a negative pressure in the negative pressure groove 4111, so that the user's skin is sucked into the negative pressure groove 4111 under the action of the negative pressure.

[0264] When working, the RF electrode 420 of the beauty head 030 releases RF current to the skin sucked into the negative pressure tank 4111, so that the RF electrode 420 acts on the skin deeper. In addition, the area of ​​the skin contacting the RF electrode 420 increases, and the RF electrode 420 can release RF current to a larger area of ​​skin, thereby improving the efficiency of RF current beauty treatment.

[0265] It can be understood that the first airflow connection part 232 can also be set as a negative pressure pipeline, and the first airflow connection part 232 does not extend out of the assembly slot 212a. The second airflow connection part 4114 can also be set as an airflow connection tube, and the second airflow connection part 4114 extends out of the housing 411. When the beauty head 030 is installed in the assembly slot 212a, the airflow connection tube of the beauty head 030 is inserted into the negative pressure pipeline of the connection module 200.

[0266] Furthermore, the beauty head 030 further includes a breathable member 413 for preventing dirt and allowing air to pass through. The breathable member 413 is disposed in the second airflow connection portion 4114. Thus, by disposing the breathable member 413 in the second airflow connection portion 4114, gas is allowed to pass through, while liquid, sweat stains, gel and other debris are prevented from passing through, thereby preventing them from entering the air path in the main body 010 and contaminating the air path.

[0267] Specifically, the first airflow connection part 232 is inserted into the second airflow connection part 4114 to form an airflow duct, so that the beauty head 030 and the main body 010 are connected. When the first airflow connection part 232 is inserted into the second airflow connection part 4114, the first airway hole 232a is connected to the second airway hole 411a. The air permeable member 413 is located at the entrance of the first airflow connection part 232. When the first airflow connection part 232 sucks the gas in the negative pressure groove 4111 through the second airflow connection part 4114, the gas in the negative pressure groove 4111 will first pass through the air permeable member 413 and then enter the first airflow connection part 232. Through the filtering of the air permeable member 413, the impurities entering the first airflow connection part 232 can be reduced, and the probability of the first airflow connection part 232 being blocked or breeding bacteria can be reduced. Optionally, the air permeable member 413 can include air permeable cotton, which can not only make the gas circulate, but also filter the circulating gas. And the air permeable cotton is easy to replace at a low cost.

[0268] Optionally, the breathable member 413 may further include a waterproof breathable membrane, which can reduce the probability of water vapor flowing through the breathable cotton and entering the main body 010. The waterproof breathable membrane may be made of Teflon and disposed on the surface of the breathable cotton, thereby reducing the probability of water vapor entering the breathable cotton through the negative pressure groove 4111.

[0269] Specifically, the ventilation area of ​​the connection channel of the second airflow connection part 4114 near the first airflow connection part 232 is smaller than the notch area of ​​the negative pressure groove 4111. This makes the air flow speed at the notch of the negative pressure groove 4111 slower, reducing the stimulation of the airflow to the skin.

[0270] Specifically, the housing 411 is further provided with an anti-blocking groove 4115 on the bottom wall of the negative pressure groove 4111. The anti-blocking groove 4115 is located on the outside of the second airflow connection part 4114, and the anti-blocking groove 4115 is connected to the second airflow connection part 4114. When the user's skin is installed in the negative pressure groove 4111, the second airflow connection part 4114 may be blocked by the user's skin. However, the user's skin is tough and it is difficult to produce severe deformation locally, so it is difficult to completely block the anti-blocking groove 4115 whose size is smaller than the second airflow connection part 4114. When the second airflow connection part 4114 is blocked by the user's skin, the second airflow connection part 4114 can continue to generate negative pressure in the negative pressure groove 4111 through the anti-blocking groove 4115.

[0271] Optionally, the airflow duct further includes a filter trough disposed at the bottom of the negative pressure trough 4111 to communicate with the negative pressure trough 4111, the filter trough communicates with the inlet of the first airflow connection portion 232, and the air permeable member 413 is disposed in the filter trough to limit impurities from entering the airflow duct; the filter trough communicates with the anti-blocking trough 4115. Providing the filter trough at the bottom of the negative pressure trough 4111 is conducive to making full use of the notch of the negative pressure trough 4111 when sucking gas, so as to improve the suction efficiency, and the air permeable member 413 is disposed in the filter trough, which can reduce the possibility of impurities entering the airflow duct, and reduce the probability of the airflow duct being blocked or breeding bacteria.

[0272] Fig.17 A schematic structural diagram of a beauty head 030 in one embodiment of the present application is shown. Fig.18 A schematic structural diagram of a shell 411 of a beauty head 030 in one embodiment of the present application is shown.

[0273] See also Fig.17 and Fig.18 , the cover body 412 is provided with a clamping portion 4123. The clamping portion 4123 protrudes from a side of the cover body 412 away from the housing 411. A clamping slot 41231 is provided on one side of the clamping portion 4123. After the hook 22111 is inserted into the clamping slot 41231, the beauty head 030 and the main body 010 can be relatively fixed along the first inclined direction U. The clamping portion 4123 is inserted into the buckle movable hole 2112, and the hook 22111 moves in the buckle movable hole 2112 along the second inclined direction V to be inserted into the clamping slot 41231 of the clamping portion 4123.

[0274] The beauty head 030 also includes a radio frequency electrode 420. The mounting shell 410 has a skin-contacting surface 410c for fitting the user's face, the radio frequency electrode 420 is exposed on the skin-contacting surface 410c, the negative pressure groove 4111 is arranged on the skin-contacting surface 410c, and a plurality of radio frequency electrodes 420 are arranged on the circumference of the negative pressure groove 4111; optionally, the skin-contacting surface 410c is arranged on the negative pressure end 410a. The radio frequency electrode 420 is connected to the shell 411. When the beauty head 030 contacts the user's skin, the radio frequency electrode 420 can emit radio frequency current to the user's skin, thereby achieving a beauty effect. The radio frequency electrode 420 is arranged on the inner wall of the negative pressure groove 4111. The negative pressure formed in the negative pressure groove 4111 causes the user's skin to deform and fit the radio frequency electrode 420, and then the radio frequency current is emitted by the radio frequency electrode 420 to beautify the user's skin. Compared with the roughly flat skin that is not absorbed by the negative pressure, the radio frequency current can penetrate the skin sucked into the negative pressure groove 4111, thereby increasing the injection depth of the radio frequency energy and improving the beauty effect.

[0275] The notch of the negative pressure groove 4111 forms an adsorption port, which is used to fit the skin so that the negative pressure groove 4111 negatively adsorbs the skin; the orientation of the adsorption port is inclined to the extension direction of the housing 100, and the radio frequency electrode 420 is arranged at the adsorption port. It can be understood that the radio frequency electrode 420 is arranged at the adsorption port, including the radio frequency electrode 420 being arranged inside the negative pressure groove 4111 and close to the notch, and the radio frequency electrode 420 being arranged outside the negative pressure groove 4111 and close to the notch. In this way, by arranging the radio frequency electrode 420 at the adsorption port, the radio frequency path can be reduced and the beauty effect can be improved.

[0276] It is understandable that the RF electrode 420 can also be set at a distance outside the adsorption port to release RF current to the skin that is not adsorbed, so that the RF current can flow deeper under the skin and improve the beauty effect.

[0277] The shell 411 is provided with a mounting notch 4101 in the negative pressure groove 4111. The RF electrode 420 is provided at the mounting notch 4101, so that after the RF electrode 420 and the shell 411 are connected, the surface of the RF electrode 420 and the inner wall of the negative pressure groove 4111 are smoothly transitioned. It can be understood that the RF electrode 420 can be at least partially provided in the negative pressure groove 4111 so that the RF electrode 420 can release RF current to the adsorbed skin, or the RF electrode 420 can be completely provided outside the negative pressure groove 4111 so that the RF electrode 420 is located on the outer peripheral side of the negative pressure groove 4111, thereby releasing RF current to the contacted skin.

[0278] It can be understood that the RF electrode 420 can be partially disposed in the negative pressure groove 4111, so that the RF electrode 420 can release RF current to the skin absorbed into the negative pressure groove 4111. The RF electrode 420 can also be completely disposed outside the negative pressure groove 4111, so that the RF electrode 420 is located at the end of the housing 411, and when the user's skin contacts the RF electrode 420, the RF current is released to the skin between the paired RF electrodes 420.

[0279] Specifically, the RF electrode 420 has a bottom end 421, a top end 422 and a skin-contacting side surface connecting the top end 422 and the bottom end 421. The bottom end 421 of the RF electrode 420 faces the bottom wall of the negative pressure groove 4111. When the beauty head 030 contacts the user's skin, the top end 422 of the RF electrode 420 abuts the user's skin. The top end 422 of the RF electrode 420 has a working arc surface 423, and / or the connection between the skin-contacting side surface and the top end 422 forms a working arc surface 423. Optionally, the working arc surface 423 has a bending axis, and the bending axis is substantially perpendicular to the first tilting direction U. When the user's skin is adsorbed by negative pressure, the skin adsorbed by the negative pressure into the negative pressure groove 4111 is deformed according to the support of the working arc surface 423, so that the deformation of the skin can be made to conform to the skin deformation characteristics, thereby improving the user's comfort, while increasing the contact area between the RF electrode 420 and the user's skin, thereby improving the beauty efficiency and the beauty effect.

[0280] The RF electrode 420 has a thickness. The thickness of the RF electrode 420 is the dimension from the side of the RF electrode 420 facing the center of the negative pressure groove 4111 to the side of the RF electrode 420 away from the center of the negative pressure groove 4111. The thickness of the RF electrode 420 can be 2 to 5 mm. The arc diameter of the working arc surface 423 can be 2 to 5 mm. Increasing the thickness of the RF electrode 420 can reduce the power loss of the RF electrode 420 from the bottom end 421 to the top end 422, while increasing the curvature of the working arc surface 423, thereby increasing the contact area between the RF electrode 420 and the user's skin. Reducing the thickness of the RF electrode 420 can reduce the cost of the RF electrode 420 and improve the energy concentration of the RF current of the RF electrode 420.

[0281] The beauty head 030 further includes a first temperature sensor 430. The first temperature sensor 430 is used to sense the temperature of the RF electrode 420. The first temperature sensor 430 contacts the RF electrode 420 to sense the temperature of the RF electrode 420. The temperature of the RF electrode 420 is sensed by the first temperature sensor 430. When the temperature of the RF electrode 420 rises beyond an acceptable threshold, the beauty instrument 001 can remind the user, or reduce the RF current energy, or even directly stop the RF current of the RF electrode 420, thereby reducing the risk of the user being scalded by the RF electrode 420. When the user's skin contacts the RF electrode 420, the user's skin in contact with the RF electrode 420 and the RF electrode 420 transfer heat, so that the temperature of the user's skin in contact with the RF electrode 420 is roughly equivalent to the temperature of the RF electrode 420. The first temperature sensor 430 can also reflect the current temperature of the user's skin in contact with the RF electrode 420, which can be used as a reference for adjusting the RF power of the RF electrode 420. The first temperature sensor 430 can be an NTC (Negative Temperature CoeffiCient, negative temperature coefficient) sensor. Under limited measurement power, the resistance value of NTC thermistor decreases rapidly as the temperature rises. The corresponding temperature can be determined by measuring the resistance value of NTC thermistor, thereby achieving the purpose of temperature detection.

[0282] Optionally, the number of the RF electrodes 420 is two. The two RF electrodes 420 are arranged opposite to each other, and the second airflow connection part 4114 is located between the two RF electrodes 420. Observing the negative pressure groove 4111 along the first inclined direction U, the inner wall of the negative pressure groove 4111 located between the two RF electrodes 420 is curved, so that the negative pressure groove 4111 accommodating two RF electrodes 420 is roughly in the shape of a runway. The inner wall of the negative pressure groove 4111 located between the two RF electrodes 420 also has an inner chamfer. When the user's skin is adsorbed by negative pressure, the skin adsorbed by the negative pressure into the negative pressure groove 4111 is deformed according to the support of the inner chamfer, so that the deformation of the skin can be made to conform to the skin deformation characteristics, thereby improving the comfort of the user.

[0283] Optionally, the distance between the two RF electrodes 420 is greater than or equal to 8 mm and less than or equal to 20 mm. In this way, it is beneficial to take into account the size of the negative pressure groove 4111 so that the skin of an appropriate area can be sucked into the negative pressure groove 4111, and on the other hand, it can have a sufficient RF distance, improve the efficiency of RF current stimulating the skin, reduce the possibility of excessive concentration of RF energy causing excessive skin temperature, and reduce the risk of burns to the user.

[0284] In some embodiments, the distance between the two RF electrodes 420 is any one of 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, and 19mm. In this way, it is beneficial to take into account the size of the negative pressure tank 4111, so that the skin of an appropriate area can be sucked into the negative pressure tank 4111, and on the other hand, it can have a sufficient RF distance, improve the efficiency of RF current stimulating the skin, reduce the possibility of excessive concentration of RF energy causing excessive skin temperature, and reduce the risk of burns to the user.

[0285] Preferably, the distance between the two RF electrodes 420 is greater than or equal to 10 mm and less than or equal to 15 mm.

[0286] Fig.19 A schematic structural diagram of a beauty head 030 in one embodiment of the present application is shown, wherein the number of radio frequency electrodes 420 is four.

[0287] Optionally, the number of RF electrodes 420 is four. The four RF electrodes 420 are located on the four sides of the quadrangular prism, and every two opposite RF electrodes 420 are arranged in parallel. The negative pressure groove 4111 has four side walls, and the four side walls correspond to the four RF electrodes 420 respectively. A spacing surface 41111 is formed between two adjacent side walls. The spacing surface 41111 is also located between two adjacent RF electrodes 420. The spacing surface 41111 can be a plane or a curved surface. When the spacing surface 41111 is a plane, the angle between the spacing surface 41111 and any adjacent RF electrode 420 is greater than 100°. The negative pressure groove 4111 has a first dimension along the second inclined direction V, and a second dimension along the third direction Z. The first dimension is greater than the second dimension. The angle between the two RF electrodes 420 spaced apart along the second inclined direction V and the adjacent spacing surface 41111 is between 100 and 120°. For example, the angle between the two RF electrodes 420 spaced apart along the second inclined direction V and the adjacent spacing surface 41111 is 105°, 110° or 115°. The angle between the two RF electrodes 420 spaced apart along the second direction Y and the adjacent spacing surface 41111 is between 150 and 170°. For example, the angle between the two RF electrodes 420 spaced apart along the second direction Y and the adjacent spacing surface 41111 is 155°, 160° or 165°. By limiting the angle between the spacing surface 41111 and the RF electrode 420, the overall contour of the negative pressure groove 4111 is roughly flat. When the user's skin is subjected to negative pressure adsorption, the contour of the portion deformed by the negative pressure adsorption roughly matches the contour of the negative pressure groove 4111, thereby improving the user's comfort.

[0288] The spacing surface 41111 may also be a curved surface, and the angle between the section of the curved surface approximately close to one end of any RF electrode 420 and the corresponding RF electrode 420 is greater than 100°. This makes the transition position between the spacing surface 41111 and any RF electrode 420 approximately flat. When the user's skin is subjected to negative pressure adsorption, the contour of the part deformed by the negative pressure adsorption roughly matches the contour of the negative pressure groove 4111, thereby improving the user's comfort.

[0289] The above briefly introduces the distribution of the RF electrode 420 in the negative pressure tank 4111, but does not summarize it. In order to better express the design concept of the present application, the following makes some summary explanations and descriptions of the installation of the RF electrode 420 in the negative pressure tank 4111.

[0290] Specifically, the RF electrode 420 is at least partially disposed on the side wall of the negative pressure groove 4111, and the RF electrode 420 forms a plurality of RF zones in the circumferential direction of the negative pressure groove 4111, and adjacent RF zones have a spacing surface 41111, and the spacing surface 41111 is inclined to the bottom of the negative pressure groove 4111, and / or adjacent RF zones smoothly transition through the spacing surface 41111.

[0291] Specifically, the RF electrode 420 can be entirely disposed on the side wall of the negative pressure groove 4111, or part of the RF electrode 420 can be disposed on the side surface (i.e., the skin-contacting surface 410c) of the periphery of the negative pressure groove 4111 and part of the RF electrode 420 can be disposed on the side wall of the negative pressure groove 4111. In this way, the RF electrode 420 can emit more energy into the skin sucked into the negative pressure groove 4111 and can make the RF path shorter.

[0292] There are multiple RF electrodes 420, and the multiple RF electrodes 420 form multiple RF zones in the circumferential direction of the negative pressure groove 4111. It can be understood that the RF electrodes 420 can be arranged in a sheet shape, or can be distributed in a point shape, or can be arranged in other forms. When the RF electrodes 420 are arranged in a sheet shape, each RF electrode 420 can form a RF zone; when the RF electrodes 420 are arranged in a point shape, a plurality of point-shaped RF electrodes 420 can be distributed together to form a RF zone. The RF zone has a RF surface.

[0293] Among them, the side walls of the negative pressure groove 4111 between adjacent radio frequency zones form a spacing surface 41111. Through the inclined setting of the spacing surface 41111 and the bottom of the negative pressure groove 4111, when the user's skin is adsorbed by negative pressure, the skin adsorbed into the negative pressure groove 4111 by the negative pressure can be deformed according to the support of the spacing surface 41111, so that the deformation of the skin can be consistent with the skin deformation characteristics, thereby improving the user's comfort.

[0294] It can be understood that, based on basically the same reasons, the bottom of the negative pressure groove 4111 of the RF surface of the RF zone can also be set at an angle, and adjacent RF zones can be smoothly transitioned through the spacing surface 41111.

[0295] For example, for a non-circular negative pressure groove 4111, this type of negative pressure groove 4111 has multiple side walls, and some of the side walls can be set as RF side walls, that is, the negative pressure groove 4111 has multiple RF side walls, each RF side wall is provided with an RF electrode 420, and the RF electrode 420 and the side wall where it is located form a RF surface; it can be understood that when the RF electrode 420 is installed on the RF side wall, the side of the RF electrode 420 or the side of the RF electrode 420 and the RF side wall together can form a RF surface. The side wall located between two adjacent RF side walls forms a partition surface 41111 which divides the two RF surfaces. That is to say, the negative pressure groove 4111 also has a partition surface 41111 located between two adjacent side walls. In order to make the deformation of the skin conform to the skin deformation characteristics to improve comfort, it can be made that: the angle between the RF surface and the partition surface is greater than 100°; and / or the partition surface 41111 and the bottom of the negative pressure groove 4111 are arranged in an inclined state; and / or the RF surface and the bottom of the negative pressure groove 4111 are arranged in an inclined state.

[0296] In one embodiment, the negative pressure groove 4111 is designed to be roughly square, so that the number of RF electrodes is four, and the four RF electrodes 420 are distributed on the four sides of the negative pressure groove 4111, and the spacing surfaces 41111 are formed at the four corners. In another embodiment, the negative pressure groove 4111 is designed to be roughly square, and the number of RF electrodes 420 is two, and the two RF electrodes 420 are distributed on two opposite sides of the negative pressure groove 4111, and the other two sides form the spacing surfaces 41111.

[0297] It should be noted that when the negative pressure groove 4111 is roughly circular, it can still be arranged according to the above design method.

[0298] Furthermore, in some embodiments, multiple RF electrodes 420 can be arranged in a ring shape, and multiple RF electrodes 420 arranged in a ring shape form multiple electrode groups. The main control board 310 is used to control the multiple electrode groups to work in sequence according to a preset working order, and the stimulation ranges of the multiple electrode groups are cross-distributed.

[0299] The electrode group refers to an electrode combination including at least one positive electrode and one negative electrode, such as one positive electrode and one negative electrode, one positive electrode and multiple negative electrodes, or multiple positive electrodes and one negative electrode. During operation, radio frequency energy is emitted from the positive electrode and passes through the skin to the negative electrode. The process through which the radio frequency energy flows is the stimulation range of the electrode group.

[0300] Among them, it can be understood that the multiple electrode groups working in sequence according to the preset working order may include the following three forms: ① The working time of the two pairs of electrodes working adjacently overlaps partially, that is, the previous electrode group starts working first, and when its work is not completed, the next electrode group starts working, and it still works for a period of time after the previous electrode group finishes working, such as the previous electrode group works in the 0th to 3rd seconds, and the next pair of electrodes works in the 2nd to 6th seconds; ② The working time of the two pairs of electrodes working adjacently is postponed, that is, the main control board 310 is used to control the multiple electrode groups to work alternately in sequence according to the preset working order, that is, the previous electrode group starts working first, and when its work is completed, the next electrode group starts working immediately and works for a period of time, such as the previous electrode group works in the 0th to 3rd seconds, and the next pair of electrodes works in the 3rd to 6th seconds; ③ The working time of the two pairs of electrodes working adjacently has an interval, that is, the previous electrode group starts working first, and after its work is completed, the next electrode group starts working a short time later and works for a period of time, such as the previous electrode group works in the 0th to 3rd seconds, and the next pair of electrodes works in the 4th to 7th seconds.

[0301] For the above three forms, the start-up time of two pairs of electrode groups working adjacently is different, and the electrode group that starts working first stops working first, so that the working time of each pair of electrode groups can be shorter than the working time in the intersection area.

[0302] The stimulation ranges of multiple electrode groups are cross-distributed, which means that the stimulation ranges of different electrode groups overlap. Fig.19 As shown, the four electrodes form two electrode groups, and the enclosed portion in the middle is the overlapping portion.

[0303] In this way, by setting up multiple electrode groups with cross-distributed stimulation ranges, and making each electrode group work in sequence according to a preset working order, the skin corresponding to the area where the stimulation ranges of multiple electrode groups overlap can be continuously electrically stimulated within one cycle, so that the skin in this area is always heated, making it comparable to the skin temperature corresponding to the RF electrode 420, thereby improving the balance of beauty and enhancing the user experience.

[0304] In particular, for the beauty instrument 001 with a negative pressure groove 4111, the skin can be first sucked into the negative pressure groove 4111, and then the multiple electrode pairs can be controlled to work in sequence according to a preset working order, so as to emit a radio frequency current to the skin after suction through the radio frequency electrode 420, so that the radio frequency current can penetrate the skin sucked into the negative pressure groove 4111, thereby increasing the injection depth of the radio frequency energy and improving the beauty effect; and the skin sucked into the negative pressure groove 4111 can be continuously electrically stimulated, so as to achieve both increased radio frequency depth and improved radio frequency uniformity.

[0305] For example, Fig.19For the beauty instrument 001 with four RF electrodes 420 shown, every two opposing RF electrodes 420 form an electrode group. Specifically, two RF electrodes 420 spaced apart along the second tilt direction V form a first electrode group. Two RF electrodes 420 spaced apart along the second direction Y form a second electrode group. The electrical connection between the main body 010 and the beauty head 030 is achieved by connecting the main body circuit board 250 and the head circuit board 460, so that the main control board 310 can cross the RF by controlling the first electrode group and the second electrode group.

[0306] Optionally, the cross radio frequency of the first electrode group and the second electrode group may include three radio frequency stages. The first radio frequency stage is: the first electrode group emits radio frequency current for 0.5s, the second electrode group does not emit radio frequency current, and then enters the second radio frequency stage. The second radio frequency stage is: the second electrode group emits radio frequency current for 0.5s, the first electrode group does not emit radio frequency current, and then enters the third radio frequency stage. The third radio frequency stage is: the first electrode group and the second electrode group uniformly stop emitting radio frequency current for 0.5s, and then return to the first radio frequency stage.

[0307] Optionally, the cross-RF of the first electrode group and the second electrode group may include five RF stages. The first RF stage is: the first electrode group emits a RF current with gradually increasing energy for 0.5s, and the second electrode group does not emit a RF current, and then enters the second RF stage. The second RF stage is: the first electrode group emits a RF current with gradually decreasing energy for 0.5s, and the second electrode group does not emit a RF current, and then enters the third RF stage. The third RF stage is: the second electrode group emits a RF current with gradually increasing energy for 0.5s, and the first electrode group does not emit a RF current, and then enters the fourth RF stage. The fourth RF stage is: the second electrode group emits a RF current with gradually decreasing energy for 0.5s, and the first electrode group does not emit a RF current, and then enters the fifth RF stage. The fifth RF stage is: the first electrode group and the second electrode group evenly stop emitting RF current for 0.5s, and then return to the first RF stage.

[0308] It is understandable that the number of the RF electrodes 420 can be other. For example, when the number of the RF electrodes 420 is six, every two opposing RF electrodes 420 form an electrode group. The main control board 310 can be connected to the main circuit board 250 and the head circuit board 460 (such as Fig.18 As shown) control the cross radio frequency of each electrode group.

[0309] Furthermore, the main control board 310 can control the multiple electrode groups to work periodically, and can also control the negative pressure tank 4111 to periodically absorb the user's skin, and the working cycle of the electrode group is the same frequency as the absorption cycle of the negative pressure tank 4111; in one cycle, the main control board 310 controls the air pump 510 to absorb the skin into the negative pressure tank 4111, and controls the multiple electrode groups to work in sequence according to the preset working order, and releases the skin after the multiple electrode groups finish working. In this way, the process of negative pressure absorption of the skin is combined with the process of radio frequency work, which can improve the beauty effect.

[0310] In some embodiments, the negative pressure tank 4111 can achieve periodic adsorption and release of the skin under the regulation of the air source component 500. The RF electrode 420 realizes multiple RF stages by forming different electrode groups. The interval time between two adjacent RF stages can just correspond to the time when the negative pressure tank 4111 releases the skin. On the one hand, it can reduce the probability that the RF electrode 420 only acts on the unadsorbed skin, resulting in a decrease in the beauty effect of the RF electrode 420. On the other hand, there can be a time gap, in which the RF current is not released to the skin without adsorbing the skin, so that the skin is fully buffered and the user's pain is reduced.

[0311] Furthermore, the beauty head 030 also includes a second temperature sensor 450. A working hole 4116 is provided on the bottom wall of the negative pressure groove 4111 on the housing 411. The second temperature sensor 450 is disposed in the working hole 4116. The second temperature sensor 450 is disposed toward the negative pressure groove 4111, and the second temperature sensor 450 can measure the temperature of the skin installed in the negative pressure groove 4111. Optionally, the second temperature sensor 450 is an infrared sensor, which determines the skin temperature by measuring the infrared radiation of the skin.

[0312] Furthermore, the beauty head 030 also includes a protective plate 451, which is a light-transmitting plate. The protective plate 451 is arranged on the end surface of the working hole 4116 facing the negative pressure groove 4111, and the protective plate 451 can protect the second temperature sensor 450. The protective plate 451 can transmit infrared light, so that the second temperature sensor 450 can detect the infrared radiation of the skin. The protective plate 451 can also limit the flow of gas through the working hole 4116, reducing the effect of the working hole 4116 on the negative pressure formed in the negative pressure groove 4111. The protective plate 451 can be a silicon wafer, which has light transmittance in the infrared band, so that infrared light can pass through the silicon wafer. Moreover, the silicon wafer is stable in nature and is not easy to react and lose its light transmittance in the infrared band when exposed to air.

[0313] Fig. 20 A schematic structural diagram of a beauty head 030 in one embodiment of the present application is shown, wherein the cover body 412 is detached. Fig.21A cross-sectional view of a beauty head 030 in one embodiment of the present application is shown, wherein the cross-sectional view position is the position of a group of second electrical connectors 470 .

[0314] See also Fig. 20 and Fig.21 The beauty head 030 further includes a head circuit board 460, which is electrically connected to the radio frequency electrode 420. The head circuit board 460 is disposed in the accommodating cavity 4112. The head circuit board 460 has a clearance through hole 4602. The second airflow connection portion 4114 extends toward the cover body 412, passes through the clearance through hole 4602, and is connected to the negative pressure hole 4122. The head circuit board 460 is also provided with an avoidance groove 461, which avoids the first matching column 4113.

[0315] Optionally, the housing 411 is further provided with a second matching column 4117 in the accommodating cavity 4112, and the head circuit board 460 is provided with a second matching hole 4601. The bolt passes through the second matching hole 4601 and is threadedly matched with the second matching column 4117, so that the head circuit board 460 and the housing 411 can be connected.

[0316] Furthermore, the head circuit board 460 is also provided with connection contacts 464 .

[0317] Optionally, the connection contact 464 may include a first type electrical contact 462. The first type electrical contact 462 is electrically connected to the first temperature sensor 430. The head circuit board 460 may provide electrical energy to the first temperature sensor 430, and may also collect electrical signals sent by the first temperature sensor 430. The electrical connection between the first temperature sensor 430 and the first type electrical contact 462 may be achieved by welding a wire or by providing a flat cable.

[0318] The connection contacts 464 may include second type electrical contacts 463. The second type electrical contacts 463 are electrically connected to the second temperature sensor 450. The head circuit board 460 may provide electrical energy to the second temperature sensor 450, and may also collect electrical signals sent by the second temperature sensor 450. The electrical connection between the second temperature sensor 450 and the second type electrical contacts 463 may be achieved by welding wires or by providing flat cables.

[0319] The connection contacts 464 may include third-type electrical contacts, and the third-type electrical contacts are electrically connected to the RF electrodes 420 by welding wires or wiring.

[0320] The connection contacts 464 may include fourth type electrical contacts, and the fourth type electrical contacts are used to cooperate with the internal circuit of the head circuit board 460 to identify the type of the beauty head 030 .

[0321] Optionally, the cover body 412 is provided with a connecting through hole 4126 , and the connecting through hole 4126 can be provided corresponding to the connecting contact 464 .

[0322] Furthermore, the beauty head 030 also includes a head electrical connector. The head electrical connector is the second electrical connector 470. Optionally, the second electrical connector 470 is a PIN needle, which can be called an electrically controlled PIN needle. One end of the second electrical connector 470 is installed on the cover body 412, and is exposed from the cover body 412 to form a pin point to be electrically connected to the first electrical connector 240; the other end of the second electrical connector 470 elastically contacts or abuts against the head circuit board 460 to be electrically connected to the head circuit board 460. In this way, by fixing one end of the second electrical connector 470 on the cover body 412, on the one hand, the second electrical connector 470 can be fixed, and on the other hand, a pin point can be formed, and when installed on the head shell 110, the head circuit board 460 can also be elastically contacted or abutted with the other end of the second electrical connector 470 to achieve electrical connection.

[0323] Specifically, the second electrical connector 470 includes a first needle segment 471 and a second needle segment 472, and the first needle segment 471 and the second needle segment 472 are slidably connected. The first needle segment 471 contacts and cooperates with the connection contact 464. The second needle segment 472 passes through the connection through hole 4126 to be exposed from the second assembly surface 412a through the connection through hole 4126 to form a pin point.

[0324] Optionally, the second needle segment 472 includes a small diameter segment 4721 and a large diameter segment 4722. The small diameter segment 4721 is equivalent to the profile of the connecting through hole 4126, so that the small diameter segment 4721 can be installed in the connecting through hole 4126 and exposed from the end of the cover body 412 away from the housing 411. The large diameter segment 4722 can abut against the cover body 412, thereby limiting the second needle segment 472 from continuing to extend through the connecting through hole 4126. That is, on the projection surface perpendicular to the extension direction of the large diameter segment 4722, the large diameter segment 4722 is at least partially located outside the projection of the connecting through hole 4126, so that the large diameter segment 4722 can abut against the cover body 412. The first needle segment 471 and the second needle segment 472 have relatively far-away elasticity. By applying external force to the first needle segment 471 and the second needle segment 472, the first needle segment 471 and the second needle segment 472 can slide relative to each other to reduce the size of the second electrical connector 470. When the external force is eliminated, the first needle segment 471 and the second needle segment 472 can be relatively separated by elastic force to extend the size of the second electrical connector 470. Optionally, the second needle segment 472 is limitedly connected to the mounting shell 410 to limit the relative position of the electric control PIN needle and the mounting shell 410; for example, the second needle segment 472 is fixedly connected to the cover body 412, and the fixed connection can be in the form of bonding, welding, etc.

[0325] It is understandable that the second electrical connector 470 may also be other structures. For example, the second electrical connector 470 is a metal rod, one end of which is electrically connected to the head circuit board 460 , and the other end of which is exposed from the cover 412 .

[0326] When the cover 412 and the housing 411 are connected, the first needle segment 471 can elastically abut against the connection contact 464 of the head circuit board 460. Even if there is a distance deviation between each connection contact 464 and the corresponding connection through hole 4126, the second electrical connector 470 corresponding to each connection contact 464 can also match the deviation by its own expansion and contraction. The second needle segment 472 forms a second electrical contact at one end away from the first needle segment 471. The second electrical contact cooperates with the first electrical contact of the first electrical connector 240 to realize the electrical connection between the beauty head 030 and the connection module 200.

[0327] Optionally, the side of the first needle segment 471 facing away from the second needle segment 472 is a spherical surface. When the spherical surface contacts the connection contact 464, it can be approximately located at the center of the connection contact 464. Compared with the first needle segment 471 having a flat surface facing away from the second needle segment 472, when the spherical surface abuts against the head circuit board 460, the head circuit board 460 is not likely to generate a torque on the first electrical connector 240, thereby causing the relative sliding of the first needle segment 471 and the second needle segment 472 to become stuck. The ball head can maintain stable contact with the connection contact 464.

[0328] Optionally, there are multiple second electrical connectors 470, such as multiple second electrical connectors 470 divided into two groups, such as ten. Five second electrical connectors 470 form a group, and the two groups of second electrical connectors 470 are respectively located on both sides of the mounting shell 410. The negative pressure hole 4122 is located between the two groups of second electrical connectors 470.

[0329] When the beauty head 030 is connected to the main body 010, the plurality of second electrical connectors 470 correspond to the plurality of first electrical connectors 240 one by one, that is, ten second electrical connectors 470 correspond to ten first electrical connectors 240 one by one. If each second electrical connector 470 is electrically connected to the head circuit board 460, each first electrical connector 240 is also electrically connected to the head circuit board 460. The main body circuit board 250 is electrically connected to the main control board 310, thereby making the head circuit board 460 and the main control board 310 electrically connected.

[0330] It can be understood that, from the above introduction, in order to realize multiple signal transmission, the second electrical connector 470 is usually provided with multiple ones. During the assembly or production process, one end of the second electrical connector 470 can be first installed on a part of the mounting shell 410, for example, installed on the cover 412 of the mounting shell 410. The second electrical connector 470 is exposed from the cover 412 to form a pin point electrically contacted with the first electrical connector 240, and then the cover 412 is assembled with other parts of the mounting shell 410 to realize the electrical connection of multiple second electrical connectors 470 with the head circuit board 460, so that fast and accurate assembly can be realized. It can be understood that one end of the second electrical connector 470 can be integrally injection molded with the cover 412 of the mounting shell 410, so that one end of the second electrical connector 470 is installed on a part of the mounting shell 410.

[0331] By forming a pin point through the second electrical connector 470 to electrically connect with the first electrical connector 240 exposed from the first assembly surface 212b, the connection form can be simplified, and the first electrical connector 240 and the second electrical connector 470 can also be electrically connected during the docking process of the beauty head 030 and the main body 010.

[0332] Fig. 22 A partial cross-sectional view of a beauty instrument 001 in one embodiment of the present application is shown.

[0333] See also Fig.17 and Fig. 22 Optionally, the cover 412 is further provided with an air guide 4124 and an exhaust groove 4125. The air guide 4124 and the exhaust groove 4125 are provided on a side of the cover 412 that is away from the housing 411 (i.e., the second assembly surface 412a). The air guide 4124 is provided at the center of the cover 412, and the exhaust groove 4125 extends from the air guide 4124 to the edge of the cover 412. Optionally, the air guide 4124 and the exhaust groove 4125 are located between the two sets of second electrical connectors 470.

[0334] The air guide member 4124 is provided with an air guide hole 41241 on one side thereof facing the exhaust groove 4125. The air guide member 4124 is provided with an air guide notch on one side thereof, and the air guide notch forms the air guide hole 41241.

[0335] The air guide member 4124 is integrally formed with the main body of the cover body 412 , and the air guide notch can be formed when the air guide member 4124 is formed, so the manufacturing is simple.

[0336] The gas guide 4124 is configured to be inserted into the exhaust port 216 and guide the gas from the exhaust port 216 to enter the exhaust groove 4125 .

[0337] When the beauty head 030 is installed in the assembly groove 212a, the air guide 4124 is inserted into the exhaust port 216, and the side of the cover 412 facing away from the shell 411 is tightly matched with the first assembly surface 212b, and an exhaust channel is formed between the exhaust groove 4125 and the first assembly surface 212b. The gas exhausted from the exhaust port 216 enters the exhaust groove 4125 through the guidance of the air guide 4124.

[0338] The gas in the exhaust groove 4125 is guided by the inner wall of the exhaust groove 4125 and the first assembly surface 212b, flows to the edge of the cover body 412, and further flows out of the assembly groove 212a through the gap between the side wall of the shell 411 and the side wall of the assembly groove 212a. The air guide 4124 is isolated between the exhaust groove 4125 and the first airflow connection part 232, reducing the risk of airflow flowing through the position of the first airflow connection part 232, and preventing the airflow from affecting the negative pressure effect of the negative pressure groove 4111.

[0339] In this way, through the above method, the gas flowing out of the exhaust port 216 can be guided to the exhaust groove 4125, and the assembly is simple and convenient.

[0340] It can be understood that the air guide hole 41241 can also be a through hole separately opened on one side of the air guide member 4124. For example, the air guide member 4124 is cylindrical, and a through hole is turned on one side of the cylindrical air guide member 4124 to form the air guide hole 41241. The provision of the air guide member 4124 allows the gas to enter the exhaust groove 4125 more smoothly, which is beneficial to the circulation of the gas.

[0341] It can be understood that the exhaust groove 4125 can also be provided on the first assembly surface 212b. When the first assembly surface 212b and the second assembly surface 412a are close to each other, the exhaust groove 4125 and the second assembly surface 412a form an exhaust channel.

[0342] Along the first tilt direction U, the size of the beauty head 030 is larger than the size of the assembly slot 212a. When the beauty head 030 is installed in the assembly slot 212a, and the hook 22111 and the slot 41231 are matched, the end of the beauty head 030 away from the main body 010 is located outside the assembly slot 212a. The user's skin contacts the end of the beauty head 030 away from the main body 010, and the distance from the head is maintained. The airflow drawn out through the negative pressure slot 4111 can be dissipated into the environment through the gap between the head shell 110 and the skin.

[0343] When the beauty head 030 is installed into the assembly groove 212a, the outer shell 100 and the mounting shell 410 are assembled to form a protective shell of the beauty instrument 001.

[0344] It is understandable that the housing 100 and the mounting housing 410 can also be integrally formed, so that the beauty head 030 and the main body 010 in the beauty instrument 001 are non-detachable structures. When the housing 100 and the mounting housing 410 are integrally formed, the housing 100 part and the mounting housing 410 part together form a protective shell of the beauty instrument 001.

[0345] Fig.23 A schematic structural diagram of a beauty instrument 001 in one embodiment of the present application is shown, wherein the rear shell 120 is detached. Fig.24 A schematic structural diagram of an air source assembly 500 in one embodiment of the present application is shown, wherein the gas in the negative pressure tank 4111 is sucked by an air pump 510 . Fig.25 A schematic structural diagram of an air source assembly 500 in one embodiment of the present application is shown, wherein the negative pressure groove 4111 inhales air through the air vent 5213 .

[0346] Please refer to Fig.23 , Fig.24 and Fig.25 The main body 010 further includes an air source assembly 500. The air source assembly 500 is connected to the exhaust channel and the negative pressure groove 4111. The air source assembly 500 is used to draw air from the negative pressure groove 4111 so that the negative pressure groove 4111 adsorbs the skin, or to allow air to enter the negative pressure groove 4111 to release the adsorbed skin. The control assembly is electrically connected to the air source assembly 500 to control the air source assembly 500.

[0347] The air source assembly 500 includes an air flow driving member. The air flow driving member is connected to the first air flow connection part 232, and is used to drive the air flow to flow in the first air flow connection part 232. When the first air flow connection part 232 is connected to the second air flow connection part 4114, the first air flow connection part 232 and the second air flow connection part 4114 together form an air flow duct connecting the air source assembly 500 and the negative pressure groove 4111. The air flow driving member is an air pump 510, and the control assembly includes a main control board 310. The air pump 510 is electrically connected to the main control board 310 to be turned on or off under the control of the main control board 310. The air pump 510 and the air path switching module 520 are arranged in the accommodating chamber 100a. The air pump 510 has a pump outlet 511 and a pump inlet 512. The air pump 510 can inhale gas through the pump inlet 512. The air pump 510 can discharge gas through the pump outlet 511. Optionally, the pump outlet 511 is connected to the exhaust port 216. The pump air inlet 512 can be connected to the first airflow connection part 232 through the air path switching module 520, and then connected to the negative pressure groove 4111 through the second airflow connection part 4114. When the pump air inlet 512 is connected to the first airflow connection part 232, the air pump 510 works and can suck the gas of the beauty head 030 through the first airflow connection part 232 to form a negative pressure in the negative pressure groove 4111 of the beauty head 030. The airflow driving member can also be other structures, such as a manual pump.

[0348] Optionally, the airflow driving member has a forward air extraction mode and a reverse air supply mode. In the forward air extraction mode, the airflow driving member is used to extract the gas in the negative pressure groove 4111 to absorb the skin into the negative pressure groove 4111; in the reverse air supply mode, the airflow driving member is used to supply gas to the negative pressure groove 4111 or suspend the extraction of gas in the negative pressure groove 4111 to separate the skin from the negative pressure groove 4111. In this way, the user's skin can be absorbed and released by an airflow driving member, the structure is simple, it is conducive to simplifying the structure, saving the internal space of the accommodating cavity 100a, and reducing the difficulty of assembly.

[0349] By setting the air source assembly 500 in the accommodating chamber 100a, the main body 010 itself has a structural basis for generating negative pressure. The main body 010 and the beauty head 030 can be assembled and used, and it has stronger portability compared to the external floor-standing air extraction device. Of course, the air source assembly 500 can also be externally connected. When the air source assembly 500 is fixedly connected to the shell 100 and is located outside the shell 100, the air source assembly 500 can be quickly replaced.

[0350] Further, the gas source assembly 500 also includes a gas circuit switching module 520, the main control board 310 is connected to the gas circuit switching module 520, the gas circuit switching module 520 has a gas release port 5213, and the gas circuit switching module 520 is connected between the air flow driving member and the negative pressure groove 4111; the gas circuit switching module 520 is configured to have a negative pressure mode, in which the gas circuit switching module 520 makes the air flow driving member communicate with the negative pressure groove 4111 so that the air flow driving member extracts the gas in the negative pressure groove 4111, so that the user's skin can be sucked into the negative pressure groove 4111; the gas circuit switching module 520 is configured to also have a gas release mode that makes the gas release port 5213 communicate with the negative pressure groove 4111 so that gas is delivered to the negative pressure groove 4111 through the gas release port 5213 to release the skin. The main control board 310 controls the gas circuit switching module 520 to switch between the negative pressure mode and the gas release mode. In this way, the skin can be sucked and released by the negative pressure groove 4111 by controlling the gas circuit switching module 520 to switch between the deflation mode and the negative pressure mode.

[0351] Specifically, the gas circuit switching module 520 includes an air valve. The air valve is used to control the gas flow of the beauty instrument 001. Specifically, the air valve is used to control the connection between the negative pressure tank 4111 and the air pump 510, so that the air pump 510 is used to suck gas from the negative pressure tank 4111 so that the negative pressure tank 4111 adsorbs the skin, or the air valve is used to allow the gas to enter the negative pressure tank 4111 through the air valve to release the adsorbed skin.

[0352] Optionally, the air valve is a three-way valve 521. In the negative pressure mode, the three-way valve 521 can control the pump air inlet 512 of the air pump 510 to communicate with the first air flow connection part 232 and the exhaust port 216, so that the air pump 510 can suck the gas in the negative pressure groove 4111 through the first air flow connection part 232 to form a negative pressure in the negative pressure groove 4111, and discharge the sucked gas through the exhaust port 216. In the deflation mode, the three-way valve 521 can also control the first air flow connection part 232 to communicate with the deflation port 5213, and the deflation port 5213 can provide gas to the first air flow connection part 232, thereby relieving the negative pressure of the negative pressure groove 4111, so that the skin adsorbed at the negative pressure groove 4111 is released.

[0353] It is understandable that the gas circuit switching module 520 may also be other components, for example, the gas circuit switching module 520 is a component formed by a combination of a one-way valve and a two-way valve.

[0354] When the beauty instrument 001 is working, it can cyclically form negative pressure in the negative pressure tank 4111 to absorb the skin, and release the negative pressure to release the skin, so that the skin can be absorbed and released intermittently, reducing the discomfort caused by long-term negative pressure absorption of the skin and improving the user experience.

[0355] Optionally, the air leakage port 5213 can be connected to the exhaust port 216, and when the negative pressure of the negative pressure groove 4111 needs to be released, ambient gas can be introduced through the exhaust groove 4125. The air leakage port 5213 can also be directly connected to the accommodating chamber 100a. The accommodating chamber 100a is not completely sealed, and ambient gas can also be introduced into the air leakage port 5213 through the accommodating chamber 100a.

[0356] It can be understood that the air pump 510 can be in the form of a piston pump, or a turbine pump, a vacuum pump, a vane pump, a plunger pump, a diaphragm pump, a screw pump, a peristaltic pump, etc.

[0357] Fig.26 A schematic diagram of the structure of a gas path switching module 520 in one embodiment of the present application is shown.

[0358] Please refer to Fig.24 , Fig.25 and Fig.26Optionally, the three-way valve 521 has a first valve port 5211, a second valve port 5212 and a third valve port. The third valve port is an air release port 5213. The three-way valve 521 can control the first valve port 5211 to be connected to the second valve port 5212, or the first valve port 5211 to be connected to the air release port 5213. The first valve port 5211 is connected to the first airflow connection part 232. The second valve port 5212 is connected to the pump air inlet 512. Optionally, the first valve port 5211 is connected to the first airflow connection part 232 through a hose or a spliced ​​airway, and the second valve port 5212 is connected to the pump air inlet 512 through a hose or a spliced ​​airway.

[0359] Optionally, the three-way valve 521 is a solenoid valve.

[0360] When it is necessary to draw gas from the negative pressure tank 4111, the three-way valve 521 controls the first valve port 5211 to communicate with the second valve port 5212. The gas is discharged from the environment through the path of the negative pressure tank 4111, the first airflow connection part 232, the first valve port 5211, the second valve port 5212, the pump air inlet 512, the pump air outlet 511, the exhaust port 216, and the exhaust tank 4125, so that negative pressure is formed in the negative pressure tank 4111.

[0361] When the negative pressure in the negative pressure tank 4111 needs to be released, the three-way valve 521 controls the first valve port 5211 to communicate with the air release port 5213. The gas enters the negative pressure tank 4111 through the air release port 5213, the first valve port 5211, and the first air flow connection portion 232, so that the other part in the negative pressure tank 4111 rises, thereby releasing or reducing the adsorption on the skin.

[0362] In the accommodating cavity 100a, the air circuit switching module 520 is located between the head shell 110 and the air pump 510. The pump air inlet 512 and the pump air outlet 511 of the air pump 510 are both located on the side facing the air circuit switching module 520, which facilitates the connection between the air pump 510 and the air circuit switching module 520.

[0363] The gas circuit switching module 520 also includes an air pressure detection member 522. The air pressure detection member 522 is used to detect the air pressure of the negative pressure tank 4111. Whether it is the process of extracting gas from the negative pressure tank 4111 or the process of removing the negative pressure of the negative pressure tank 4111, the negative pressure tank 4111 is connected to the first valve port 5211. The air pressure detection member 522 is set between the negative pressure tank 4111 and the first valve port 5211, and the air pressure of the negative pressure tank 4111 can be detected. In this way, by detecting the air pressure in the negative pressure tank 4111 through the air pressure detection member 522, excessive extraction can be prevented to avoid inhaling too much skin and causing pain to the user.

[0364] Furthermore, the gas circuit switching module 520 also includes a mounting frame 523. The mounting frame 523 is connected to the housing 100, and the three-way valve 521 and the air pressure detection member 522 are both arranged on the mounting frame 523. In this way, the gas valve and other components can be first installed on the mounting frame 523, and then installed into the accommodating cavity 4112 through the mounting frame 523, thereby improving the installation efficiency and facilitating the fixing of the gas valve and other components.

[0365] Optionally, a limiting hole 5231 is provided on the mounting frame 523. The housing 100 is provided with a first pre-fixing portion in the accommodating cavity 100a. The first pre-fixing portion includes a limiting column 1303. The mounting frame 523 also includes a limiting bolt (not shown in the figure). After the limiting bolt passes through the limiting hole 5231, it is threadedly connected with the limiting column 1303, so that the mounting frame 523 can be connected to the housing 100. Specifically, the limiting column 1303 is provided on the front shell 130.

[0366] Furthermore, the mounting frame 523 is provided with a valve installation cavity, wherein the valve installation cavity includes a first groove body 5232 , and the three-way valve 521 is accommodated in the first groove body 5232 .

[0367] Optionally, the opening of the first groove body 5232 is set toward the front shell 130. When the three-way valve 521 is accommodated in the first groove body 5232, the front shell 130 blocks the opening of the first groove body 5232 so that the front shell 130 abuts against the three-way valve 521 to limit the three-way valve 521 from moving away from the first groove body 5232.

[0368] Furthermore, the mounting frame 523 is provided with a first avoidance notch 5233 on the side wall of the first slot body 5232. The first avoidance notch 5233 forms a gas leakage avoidance port, and the gas leakage port 5213 of the three-way valve 521 is led out of the first slot body 5232 through the first avoidance notch 5233. In this way, by arranging the gas leakage port 5213 outside the first slot body 5232 through the first avoidance notch 5233, on the one hand, it is convenient to suck the gas inside or outside the shell 411 into the gas leakage port 5213, and on the other hand, it is convenient to reduce the volume of the first slot body 5232, so as to reduce the volume of the mounting frame 523.

[0369] Optionally, a side wall of the first avoidance gap 5233 provided in the first groove body 5232 abuts against the three-way valve 521 to limit the movement of the three-way valve 521 along the first direction X relative to the mounting frame 523 .

[0370] Furthermore, the first avoidance gap 5233 is communicated with the opening of the first groove body 5232 to facilitate the installation of the gas valve.

[0371] Optionally, the mounting frame 523 is provided with a second pre-fixing portion. The second pre-fixing portion includes a positioning groove 5234. The limiting hole 5231 is provided on the bottom wall of the positioning groove 5234. The limiting column 1303 can be installed in the positioning groove 5234 and abut against the side wall of the positioning groove 5234. Exemplarily, the front shell 130 is provided with two limiting columns 1303. When the mounting frame 523 is assembled with the outer shell 100, the mounting frame 523 is arranged between the two limiting columns 1303. When the mounting frame 523 is assembled with the outer shell 100, the front shell 130 and the mounting frame 523 can be relatively close to each other first, so that the limiting column 1303 is inserted into the positioning groove 5234, and the two limiting columns 1303 are abutted against the side walls of the corresponding positioning groove 5234, and the relative position of the mounting frame 523 and the front shell 130 is preliminarily limited. Then, the limiting bolt is passed through the limiting hole 5231 and threadedly engaged with the limiting column 1303 to strengthen the connection strength between the mounting frame 523 and the front shell 130 .

[0372] It can be understood that the first pre-fixing part and the second pre-fixing part can also be configured as follows: the first pre-fixing part includes a positioning groove 5234, and the second pre-fixing part includes a limiting column 1303. The second pre-fixing part is inserted into the first pre-fixing part to preliminarily limit the relative position of the mounting frame 523 and the front shell 130.

[0373] Further, a second slot 5235 is provided at one end of the mounting frame 523 opposite to the first slot 5232. The opening of the second slot 5235 faces the rear housing 120. The second slot 5235 is used to accommodate the air pressure detection element 522. When the mounting frame 523 is installed on the rear housing 120, the rear housing 120 blocks the opening of the second slot 5235.

[0374] Further, the air pressure detection member 522 includes an airway member 522a and an air pressure sensor 5222. The air pressure sensor 5222 is disposed between the air pump 510 and the negative pressure tank 4111, and is used to detect the air pressure of the negative pressure tank 4111. The air pressure sensor 5222 is installed on the airway member 522a, and the air pressure sensor 5222 is disposed in the detection channel 5221d, so as to detect the air pressure of the negative pressure tank 4111 through the detection channel 5221d. In this way, by adding the airway member 522a, it is convenient to dispose the air pressure sensor 5222 between the air pump 510 and the negative pressure tank 4111, and it is convenient to fix the air pressure sensor 5222 to improve the detection accuracy.

[0375] Specifically, the airway component 522a includes an airway body 5221, a detection channel 5221d is provided inside the airway body 5221, and an air pressure sensor 5222 is provided in the detection channel 5221d to detect the air pressure of the negative pressure tank 4111 through the detection channel 5221d.

[0376] Exemplarily, the airway body 5221 is formed with a first port 52211, a second port 52212 and a third port 52213 connected to the detection channel 5221d, and the third port 52213 is also called a detection port. The first port 52211 is used to communicate with the negative pressure tank 4111, and the second port 52212 is used to communicate with the air pump 510; the third port 52213 is located between the first port 52211 and the second port 52212, and the air pressure sensor 5222 is arranged at the third port 52213.

[0377] Specifically, the first valve port 5211 of the three-way valve 521 extends into the second groove body 5235 to be connected with the second port 52212 in the second groove body 5235, so that the first valve port 5211 is in communication with the detection channel 5221d.

[0378] The air duct member 522a is mounted on the mounting frame 523, and the mounting frame 523 is mounted on the protective shell, so that the air duct member 522a and the mounting frame 523 are integrally mounted on the protective shell.

[0379] Further, the airway body 5221 is fixedly mounted in the second slot body 5235. Optionally, the mounting frame 523 is provided with two mounting threaded holes 5236 at the opening of the second slot body 5235, and the airway body 5221 is provided with two locking grooves 52214. The locking grooves 52214 correspond to the mounting threaded holes 5236. The air source assembly 500 includes mounting bolts, and the two mounting bolts are partially disposed in the locking grooves 52214 and threadedly matched with the mounting threaded holes 5236. The airway body 5221 is clamped by the two mounting threaded holes 5236, thereby limiting the relative positions of the mounting bolts, the airway body 5221 and the mounting frame 523. By clamping the airway body 5221 with the head of the mounting bolt, the airway body 5221 can be limited to be relatively away from the mounting frame 523, thereby fixing the relative positions of the airway body 5221 and the mounting frame 523.

[0380] When the mounting bracket 523 is installed and connected to the front shell 130, the front shell 130 blocks the opening of the second slot 5235, and also blocks and protects the airway body 5221. When the air pressure detection component 522 needs to be inspected, the front shell 130 and the mounting bracket 523 are released to expose the air pressure detection component 522, so that the air pressure detection component 522 can be directly inspected.

[0381] It is understandable that the air source assembly 500 may not include the air pressure sensor 5222, and the air pressure sensor 5222 may be disposed at other locations. For example, if the air pump 510 has a built-in air pressure detection function, the air pressure in the negative pressure tank 4111 may be derived, and the air pressure sensor 5222 may be disposed in the negative pressure tank 4111.

[0382] Furthermore, the airway body 5221 includes an airway substrate 5221a for forming a detection channel 5221d, a first airway column 5221b and a second airway column 5221c, the first airway column 5221b is protruded from one side of the airway substrate 5221a, the second airway column 5221c is protruded from one side of the first airway column 5221b, the other side of the airway substrate 5221a forms a third port 52213 connected to the first airway column 5221b, the free end of the first airway column 5221b forms a second port 52212, the second airway column 5221c is connected to the first airway column 5221b, and the free end of the second airway column 5221c forms a first port 52211.

[0383] The first port 52211 of the detection channel 5221d is in communication with the first airflow connection portion 232. When the gas flows between the first valve port 5211 and the first airflow connection portion 232, the gas will flow through the detection channel 5221d through the first port 52211 and the second port 52212.

[0384] When it is necessary to draw gas from the negative pressure tank 4111, the three-way valve 521 is controlled to connect the first valve port 5211 with the second valve port 5212. The gas is discharged to the environment through the path of the negative pressure tank 4111, the detection channel 5221d, the first airflow connection part 232, the first valve port 5211, the second valve port 5212, the pump air inlet 512, the pump air outlet 511, the exhaust port 216, and the exhaust tank 4125, so that negative pressure is formed in the negative pressure tank 4111.

[0385] When the negative pressure in the negative pressure tank 4111 needs to be released, the three-way valve 521 is controlled to connect the first valve port 5211 with the air release port 5213. The gas enters the negative pressure tank 4111 through the air release port 5213, the first valve port 5211, the detection channel 5221d, and the first air flow connection part 232, so that the other part in the negative pressure tank 4111 rises, thereby releasing or reducing the adsorption to the skin.

[0386] Furthermore, the mounting frame 523 is further provided with an observation window 5237 on one side of the second slot body 5235. The matching condition of the first valve port 5211 and the first port 52211 in the second slot body 5235 can be observed through the observation window 5237. It is also convenient to adjust the relative position of the first valve port 5211 and the first port 52211 so that the first valve port 5211 and the first port 52211 are closely matched and air is not easily leaked at the first valve port 5211 and the first port 52211.

[0387] Furthermore, the mounting frame 523 is further provided with a second avoidance notch 52351 on the side of the second slot body 5235 opposite to the observation window 5237. The second avoidance notch 52351 forms a detection avoidance hole. A ventilation duct is provided through the second avoidance notch 52351 to connect the first port 52211 and the first airflow connection portion 232. In this way, by arranging the first port 52211 outside the second slot body 5235 through the second avoidance notch 52351, on the one hand, it is convenient to connect the first port 52211 and the first airflow connection portion 232, and on the other hand, it is convenient to reduce the volume of the second slot body 5235, so as to reduce the volume of the mounting frame 523.

[0388] Furthermore, the air pressure detection member 522 further includes an airway sealing member 5223. The airway sealing member 5223 is connected to the airway body 5221 to seal the third port 52213. In this way, the air pressure sensor 5222 can be easily installed and removed.

[0389] Optionally, the airway body 5221 is provided with a first connection hole 52215, and the airway seal 5223 is provided with a second connection hole 52231. By providing sealing bolts in the first connection hole 52215 and the second connection hole 52231, the airway seal 5223 and the airway body 5221 are closely matched, the airway seal 5223 is closely attached to the surface of the airway body 5221, and the third port 52213 is sealed.

[0392] In some embodiments, the air pressure sensor 5222 can be fixed in the airway annular protrusion 5223a by bonding or the like. In other embodiments, the air pressure sensor 5222 can be disposed at the third port 52213 and abut against the bottom wall of the countersunk hole. Specifically, when the airway seal 5223 is connected to the airway body 5221, the bottom wall of the countersunk hole and the airway seal 5223 jointly clamp the air pressure sensor 5222, and the airway annular protrusion 5223a abuts against the inner wall of the countersunk hole, thereby limiting the relative position of the air pressure sensor 5222 and the airway body 5221.

[0393] Furthermore, the air circuit switching module 520 also includes a limit plate 524, and the valve installation cavity also includes an extended limit cavity 5238.

A ventilation duct is provided through the cavity connecting port 5239 to connect the second valve port 5212 and the pump air inlet 512. In this way, by arranging the second valve port 5212 in the extended limit cavity 5238 and connecting it with the air pump 510 therein, it can be protected by the extended limit cavity 5238 to prevent the second valve port 5212 from being touched when assembling other components and affecting the air tightness.

[0394] The extended limiting cavity 5238 also has an opening. The limiting plate 524 is installed at one end of the extended limiting cavity 5238 away from the second slot 5235, that is, at the opening of the extended limiting cavity 5238. In this way, the limiting plate 524 can be used to prevent the device from falling off and provide protection.

[0395] Optionally, the limiting plate 524 limits the position through the mounting frame 523 and / or the front shell 130, such as the limiting plate 524 is clamped on the mounting frame 523. When the three-way valve 521 has a tendency to move relative to the mounting frame 523, the limiting plate 524 can also abut against the second valve port 5212 to limit the movement tendency of the three-way valve 521, thereby limiting the second valve port 5212 from being separated from the extended limiting cavity 5238.

[0396] There is a valve partition plate 523c between the first groove body 5232 and the extended limiting cavity 5238, and a connecting notch connecting the two is provided on the valve partition plate 523c to facilitate the installation of the gas valve.

[0397] Specifically, the mounting frame 523 includes a pump mounting base plate 523a and a valve enclosure plate 523b.

The inner wall of the valve enclosure plate 523b is also provided with a valve partition plate 523c, so as to define a first groove body 5232 and an extended limit cavity 5238 both having an opening (i.e., an opening) in the valve mounting cavity, so as to be used for installing the three-way valve 521. The valve enclosure plate 523b includes a first valve side plate 523b1 arranged near the air pump 510 and a second valve side plate 523b2 arranged opposite to the first valve side plate 523b1. The first valve side plate 523b1 is provided with a cavity communication port 5239, and the second valve side plate 523b2 is provided with a first avoidance notch 5233 for revealing and avoiding the air leakage port 5213.

[0399] Fig. 27 An exploded schematic diagram of the rear housing 120 and the display module 600 in one embodiment of the present application is shown. Fig.28 A schematic structural diagram of a pressing member 710 in one embodiment of the present application is shown.

[0400] Please refer to Figure 2 and Fig. 27 The main body 010 also includes a display and control component. The shell 100 has a display and control installation port 1203 connected to the accommodating cavity 100a. The display and control component is installed as a whole at the display and control installation port 1203. In this way, the display and control component can be assembled outside the shell 100 in advance and then installed as a whole on the shell 100, which can reduce the impact of the shell 100 on the assembly, thereby reducing the difficulty of assembly and improving assembly efficiency.

[0401] Furthermore, the display control component includes a display module 600 and a button module 700. The display module 600 is used to display information of the beauty instrument 001. The information of the beauty instrument 001 can be working information of the beauty instrument 001, such as the radio frequency current intensity of the radio frequency electrode 420, the fault state of the main body 010, etc., and can also be the assembly state of the beauty instrument 001, such as the type of the beauty head 030 currently connected to the main body 010.

[0402] The display module 600 is disposed in the display area of ​​the rear housing 120, and the display area is located in the area where the housing 100 transitions from the first direction X to the first inclined direction U, that is, the display area is the area on the housing 100 that transitions from the gripping portion 101 to the bending portion 121. In this way, the display area can be prevented from being blocked by the user when holding the device, and the display area can be easily enlarged.

[0403] The display module 600 includes a display circuit board 620 and a light guide assembly 630 , and the display circuit board 620 is used to emit light to the display area.

[0404] Furthermore, the display control module also includes a display control board 610. The housing 100 is provided with a display window in the display area; the display control board 610 is connected to the housing 100 at the display window; and the display circuit board 620 is used to emit light to the display control board 610. The key module 700 is mounted on the display control board 610, and the display control board 610 is mounted on the housing 100, so that the key module 700 is integrally mounted on the housing 100 through the display control board 610. In this way, by installing the key module 700 on the display control board 610 in advance, and then integrally installing the display control board 610 on the housing 100, the installation efficiency can be improved.

[0405] The display and control installation opening 1203 is provided on the rear housing 120, and the display and control board 610 is connected to the rear housing 120 at the display and control installation opening 1203. Optionally, the display and control board 610 covers the display and control installation opening 1203 to prevent debris from entering the accommodating cavity 100a through the display and control installation opening 1203.

[0406] The display and control installation opening 1203 is disposed on the side of the rear shell 120 away from the front shell 130, and is located at one end of the rear shell 120 close to the head shell 110. Specifically, the display and control installation opening 1203 is located in the area where the housing 100 transitions from the first direction X to the first inclined direction U; the display and control panel 610 is also in an arc shape.

[0407] In some embodiments, from one end away from the head shell 110 to one end close to the head shell 110, the display control board 610 bends from extending along the first direction X to extending along the first inclined direction U and is connected to the head shell 110. Along the third direction Z, the size of the display control board 610 is smaller than that of the rear shell 120.

[0408] In this embodiment, along the cross section perpendicular to the first direction X, the cross section of the first half shell is U-shaped to form an opening toward the second half shell, so that a larger internal space can be formed after the first half shell and the second half shell are assembled, but this will make the first half shell have a larger depth in the direction toward the second half shell, and the space is relatively limited during assembly. In the present application, through the overall assembly method, the influence of the first half shell on the assembly can be reduced, thereby improving the assembly efficiency.

[0409] Optionally, the rear shell 120 is provided with a limiting groove 1204 on the periphery of the display and control installation opening 1203. That is, the display and control installation opening 1203 is located at the bottom of the limiting groove 1204, and the display and control board 610 is accommodated in the limiting groove 1204. Specifically, the display and control board 610 is arranged to fit the bottom wall of the limiting groove 1204. In this way, by providing the limiting groove 1204 to accommodate the display and control board 610, it is possible to pre-position the display and control board 610 during assembly, and prevent the display and control board 610 from protruding too high after assembly. Among them, the limiting groove 1204 is provided on the outer surface of the rear shell 120, so as to further reduce the difficulty of assembly. The inner wall of the limiting groove 1204 limits the movement of the display and control board 610 relative to the rear shell 120 along the first direction X and the third direction Z.

[0410] Furthermore, the rear housing 120 is further provided with a limiting through hole 1205 in the region of the limiting groove 1204. The limiting through hole 1205 is penetrated along the second direction Y. By passing a bolt through the limiting through hole 1205 and being threadedly connected with the display control board 610, the display control board 610 and the rear housing 120 can be fixed in the second direction Y. Specifically, the display control assembly further includes a display control mounting bolt, and the display control board 610 is provided with a display control threaded hole. The display control mounting bolt passes through the limiting through hole 1205 and is threadedly matched with the display control threaded hole to install the housing 100 and the display control board 610.

[0411] Furthermore, the limiting through hole 1205 is arranged in a region within the limiting groove 1204 and outside the display and control installation opening 1203 .

[0412] Optionally, the end of the display and control board 610 facing away from the head shell 110 has a first arcuate edge 611 and a second arcuate edge 612. The first arcuate edge 611 and the second arcuate edge 612 are symmetrical along a symmetry plane, which is perpendicular to the third direction Z, and the rear shell 120 is also roughly symmetrical along the symmetry plane. A convex angle is formed between the first arcuate edge 611 and the second arcuate edge 612. A convex angle is an angle less than 180°, that is, an angle protruding outward. The first arcuate edge 611 and the second arcuate edge 612 both abut against the inner wall of the limiting groove 1204. Through the abutment between the first arcuate edge 611, the second arcuate edge 612 and the inner wall of the limiting groove 1204, the display and control board 610 can be aligned with the middle of the limiting groove 1204.

[0413] Optionally, the display circuit board 620 of the display module 600 is detachably connected to the display control board 610. The display control board 610 is generally plate-shaped. The display circuit board 620 includes a plurality of lighting components 621, which are arranged toward the display control board 610, and visible light can be emitted to the display control board 610 through the lighting components 621.

[0414] The display control board 610 is provided with a limit buckle 613 extending into the accommodating cavity 100 a . The limit buckle 613 is clamped on a side of the display circuit board 620 away from the display control board 610 , thereby limiting the display circuit board 620 from being separated from the display control board 610 .

[0415] The display circuit board 620 can be electrically connected to the main control board 310 , and the main control board 310 controls the lighting component 621 on the display circuit board 620 to emit visible light.

[0416] It is understandable that the display module 600 may not include the display circuit board 620, but integrate the functions of the display circuit board 620 into other circuit boards, for example, integrated into the main control board 310, the main control board 310 is connected to the lighting component 621, and the lighting component 621 can be integrated into the display control board 610.

[0417] Among them, the light guide component 630 is arranged between the display control board 610 and the display circuit board 620, and the light guide component 630 is used to conduct the light of the display circuit board 620 to the display control board 610. Optionally, one end of the light guide component 630 facing the display control board 610 is attached to the display control board 610, and one end of the light guide component 630 facing the display circuit board 620 is attached to the display circuit board 620. In this way, it is beneficial to improve the compactness of the overall structure of the display control component, reduce the occupation of the accommodating cavity 100a, and facilitate the installation of other components; in addition, the use of the bonding method can improve the efficiency of light guidance, so that the user can observe a higher brightness, which is convenient for the user to obtain information about the beauty instrument 001. The plate-shaped display circuit board 620 and the curved display control board 610 are matched by the light guide component 630. The light guide component 630 passes through the display control installation port 1203 to conduct the visible light of the display circuit board 620 in the accommodating cavity 100a to the display control board 610.

[0418] Optionally, the light guide assembly 630 includes a light guide member 631 and a light isolation member 632. The light guide member 631 includes at least two light guide plates 6311, and the plurality of light guide plates 6311 are spaced apart along the first direction X. The size of the light guide plate 6311 along the second direction Y is adapted to the curved surface of the display control board 610, so that one end of the light guide plate 6311 is close to the display circuit board 620, while the other end is as close to the display control board 610 as possible. Each light guide plate 6311 corresponds to at least one lighting component 621 on the display circuit board 620. The light guide member 631 transmits the visible light emitted by the lighting component 621 to the display control board 610. The area of ​​the display control board 610 corresponding to the light guide member 631 is a light-transmitting area. The user can observe the visible light transmitted by the light guide member 631 through the display control board 610.

[0419] Optionally, the light isolation member 632 includes a plurality of light isolation plates 6321, and the plurality of light isolation plates 6321 are spaced apart along the first direction X. The size of the light isolation plate 6321 along the second direction Y is adapted to the arc surface of the display control board 610, so that one end of the light isolation plate 6321 is close to the display circuit board 620, while the other end is as close to the display control board 610 as possible. A light isolation plate 6321 is arranged between each two adjacent light guide plates 6311, and the light isolation plate 6321 is used to limit the transmission of visible light between the two adjacent light guide plates 6311. Through the light isolation plate 6321, on the one hand, each light guide plate 6311 can independently guide light, reducing the color cross-talk between adjacent light guide plates 6311, and on the other hand, it can reduce the dispersion of light in the light guide plate 6311, thereby improving the light guiding effect of the light guide plate 6311.

[0420] Optionally, the light isolating member 632 is connected to the light guide member 631, and the light guide member 631 is connected to the display circuit board 620. In this way, during assembly, the light isolating member 632 and the light guide member 631 can be connected outside the housing 100, and the light guide member 631 can be connected to the display circuit board 620, and then the connected whole can be connected to the housing 100 to reduce the difficulty of assembly.

[0421] Optionally, each light guide plate 6311 has a first end face 63111 and a second end face 63112. The first end face 63111 and the second end face 63112 are substantially symmetrical along the symmetry plane. There is a convex angle between the first end face 63111 and the second end face 63112. The convex angle is an angle less than 180°, that is, an angle protruding outward. The first end face 63111 and the second end face 63112 abut against the same light isolation plate 6321, so that the light guide plate 6311 can be aligned with the middle of the rear shell 120.

[0422] Optionally, the light guide 631 further includes a first bottom plate 6312. Multiple light guide plates 6311 are connected through the first bottom plate 6312. The light isolation member 632 further includes a second bottom plate 6322. Multiple light isolation plates 6321 are connected through the second bottom plate 6322. A bottom plate mounting groove 63121 is provided on a side of the first bottom plate 6312 facing the display circuit board 620. The second bottom plate 6322 is clamped in the bottom plate mounting groove 63121 to limit the relative displacement of the light guide 631 and the light isolation member 632 along the third direction Z. The light guide plate 6311 and the light isolation plate 6321 abut against each other to limit the relative movement of the light guide 631 and the light isolation member 632 along the first direction X. A plug-in column 63122 is further provided on one side of the first bottom plate 6312 facing the display circuit board 620. The plug-in column 63122 is plugged into the display circuit board 620, so that the light guide 631 is relatively fixedly connected to the display circuit board 620. The second bottom plate 6322 is sandwiched between the first bottom plate 6312 and the display circuit board 620 to limit the relative movement of the light guide 631, the light isolation member 632 and the display circuit board 620 along the second direction Y.

[0423] Furthermore, the button module 700 is used to receive a pressing signal from the user so as to control the beauty instrument 001. The display control panel 610 is provided with a pressing window 6101, and the button module 700 is installed at the pressing window 6101 of the display control panel 610, so that the button module 700 can be observed and controlled through the pressing window 6101.

[0424] Further, the key module 700 is electrically connected to the control component, so that the control component controls the RF electrode 420 to release RF current according to the signal of the key module 700 , and / or controls the gas source component 500 according to the signal of the key module 700 .

[0425] Further, the key module 700 includes a pressing member 710 and a key circuit board 720. The pressing member 710 can move relative to the display control board 610 along the second direction Y. The key circuit board 720 is arranged in the accommodating cavity 100a. The display control board 610 is provided with an assembly column 6102. After the bolt passes through the key circuit board 720 and is threadedly connected with the assembly column 6102, the key circuit board 720 can be connected to the display control board 610. The key circuit board 720 includes a key block 721. The pressing member 710 has a flexible portion 711. When the user presses the flexible portion 711, the flexible portion 711 can be flexibly deformed and move toward the key block 721. The flexible portion 711 acts on the key block 721, which can trigger an electrical signal, so that the key circuit board 720 generates an electrical signal to control the beauty instrument 001 to work.

[0426] It is understandable that the button module 700 can also adopt a non-contact form, for example, a gesture sensing form, which can convert the user's gesture into an electrical signal to control the beauty instrument 001.

[0427] Optionally, the display control assembly is composed of a display control board 610, a display module 600 and a key module 700. The display module 600 and the key module 700 are mounted on the display control board 610, and the display control board 610 is mounted on the housing 100, so that the display module 600 and the key module 700 can be integrally mounted on the housing 100 through the display control board 610. This display control assembly can be pre-assembled and then mounted on the housing 100, which reduces the difficulty of assembling the beauty instrument 001.

[0428] Optionally, the pressing member 710 has a limiting outer edge 712. The limiting outer edge 712 is disposed in the accommodating cavity 100a. The size of the limiting outer edge 712 is larger than the size of the pressing window 6101. When the pressing member 710 moves relative to the display control board 610 along the second direction Y, the limiting outer edge 712 can abut against the display control board 610 to limit the pressing member 710 from separating from the pressing window 6101 from the display control board 610 along the second direction Y. The flexible portion 711 is disposed in the middle of the limiting outer edge 712.

[0429] It can be understood that the limiting outer edge 712 and the flexible portion 711 of the pressing member 710 can also be integrally formed. The limiting outer edge 712 and the flexible portion 711 are made of the same material. The volume of the limiting outer edge 712 is large enough so that after the limiting outer edge 712 is deformed by external force, it is not easy to shrink to the point where it can pass through the narrow area of ​​the pressing window 6101, so that it can still abut the display control board 610 to limit the pressing member 710 from separating from the pressing window 6101 from the display control board 610 along the second direction Y. If the area of ​​the flexible portion 711 is large enough, the flexible portion 711 can produce a large enough deformation to contact the button block 721 and drive the button block 721. Please refer to Fig. 27 and Fig.28 The flexible portion 711 further includes a pressing protrusion 713. The pressing protrusion 713 extends toward the pressing member 710 so that the flexible portion 711 contacts the key block 721 after being deformed.

[0430] When the user uses the beauty instrument 001, the information on the display control panel 610 can be observed to determine the state of the beauty instrument 001. The pressing member 710 is applied with a finger to drive the button block 721. After the button block 721 is driven, the main control board 310 can receive an electrical signal and change the working mode of the beauty instrument 001. Correspondingly, the display circuit board 620 matches the working mode to control the light member 621 to emit visible light. The user can judge the current working mode of the beauty instrument 001 from the information displayed on the display control panel 610, and apply force to the pressing member 710 as required to select the corresponding working mode. For example, the user needs to turn on the beauty instrument 001. If the display control panel 610 does not emit visible light, the pressing member 710 can be pressed for a long time, so that the button block 721 is pressed for a long time, and the main control board 310 receives a continuous electrical signal, then it is determined that the user needs to turn on the beauty instrument 001. After turning on the beauty instrument 001, the display control panel 610 emits visible light, and the user can determine that the current beauty instrument 001 is turned on. When the user needs to switch from the first working mode to the third working mode, the display control panel 610 is observed to emit the first color corresponding to the first working mode. The user short-presses the pressing member 710 so that the button block 721 is pressed, and the main control panel 310 receives an electrical signal, and then determines that the user needs to switch the working mode of the beauty instrument 001, and then switches the first working mode to the second working mode. The user observes the display control panel 610 again, and the display control panel 610 emits the second color corresponding to the second working mode, rather than the third color corresponding to the third working mode. At this time, the user short-presses the pressing member 710 again, so that the button block 721 is pressed, and the main control panel 310 receives an electrical signal, and then determines that the user needs to switch the working mode of the beauty instrument 001, and then switches the second working mode to the third working mode. The user observes the display control panel 610 again, and the display control panel 610 emits the third color corresponding to the third working mode, and then determines that the beauty instrument 001 is in the required third working mode.

[0431] The button module 700, the display module 600 and the display control board 610 together form a display control assembly. The button module 700, the display module 600 and the display control board 610 can be pre-assembled to form a display control assembly, and then installed together at the display control installation port 1203 of the housing 100, making the beauty instrument 001 easier to assemble.

[0432] Further, the control component also includes a radio frequency circuit board 810. The radio frequency circuit board 810 is electrically connected to the main control board 310, and the radio frequency circuit board 810 is used to control the radio frequency electrode 420 to release radio frequency current. Optionally, the radio frequency circuit board 810 can be used to connect the power line 050 to receive electric energy, and the radio frequency circuit board 810 is electrically connected to the main control board 310 to supply power to the main control board 310. Optionally, the radio frequency circuit board 810 is connected to the display control board 610, and the display control board 610 is connected to the rear shell 120, so as to limit the relative position of the radio frequency circuit board 810 and the rear shell 120.

[0433] Optionally, the main control board 310 and the radio frequency circuit board 810 are arranged around the airflow driving component.

[0434] In some embodiments, the beauty instrument 001 may further include an adapter, which is connected to the power cord 050. The adapter is connected to a household power grid or a portable power source, so that the voltage of the household power grid or the portable power source is converted into the voltage required by the beauty instrument 001, and then the electric energy is provided to the radio frequency circuit board 810. Specifically, the adapter is electrically connected to the control component, and the adapter is used to power the control component and / or the gas source component 500.

[0435] Optionally, the adapter is detachably connected to the housing 100. In this way, when there is no need to provide power to the RF circuit board 810, the user can remove the adapter from the housing 100 to facilitate storage of the beauty instrument 001 and the adapter, and when the adapter is damaged, it is also convenient to repair and replace, which is conducive to reducing the maintenance cost of the beauty instrument 001.

[0436] In another embodiment, the beauty instrument 001 may further include a battery. The battery is disposed in the accommodating cavity 100a. The battery is electrically connected to the RF circuit board 810, and the RF circuit board 810 supplies power to the main control board 310. The main control board 310 can supply power to the head circuit board 460 through the main circuit board 250, so that the RF electrode 420 can output RF current, and the main control board 310 can also supply power to the gas source assembly 500.

[0437] Furthermore, the main control board 310 is also electrically connected to the gas source assembly 500 , so that the air pump 510 can suck the gas in the negative pressure tank 4111 through the three-way valve 521 .

[0438] It is understandable that the battery and the adapter can be selected so that the beauty instrument 001 only obtains power from the battery or the adapter. The beauty instrument 001 can also include both the battery and the adapter to increase the user's freedom of choice.

[0439] It is understandable that the RF circuit board 810 may also be directly connected to the housing 100 , thereby limiting the relative position of the RF circuit board 810 and the housing 100 , so that the RF circuit board 810 can be stably disposed in the accommodating cavity 100 a .

[0440] It can be understood that the RF circuit board 810 extends along the first direction X, and the RF circuit board 810 and the main control board 310 are located on both sides of the gas source assembly 500, so that the angle between the RF circuit board 810 and the main control board 310 is between 70° and 110°, such as making the RF circuit board 810 and the main control board 310 substantially perpendicular. This can facilitate improving space utilization.

[0441] The beauty instrument 001 provided in the present application, when in use, allows the beauty head 030 to be connected to the main body 010. After the beauty head 030 is installed in the assembly groove 212a, the hook 22111 cooperates with the slot 41231 to limit the relative position of the beauty head 030 and the main body 010. When the beauty head 030 is installed in the assembly groove 212a, the first airflow connection part 232 is inserted into the second airflow connection part 4114 through the negative pressure hole 4122, so that the first airflow connection part 232 is connected to the negative pressure groove 4111. The three-way valve 521 connects the first valve port 5211 and the second valve port 5212, so that the air pump 510 can suck gas from the negative pressure groove 4111, and form a negative pressure in the negative pressure groove 4111 to absorb the skin. When the beauty head 030 is installed in the assembly groove 212a, the air guide 4124 is inserted into the exhaust port 216, and an exhaust channel is also formed between the exhaust groove 4125 and the first assembly surface 212b. The gas discharged by the air pump 510 can be discharged from the beauty instrument 001 through the exhaust port 216 and the exhaust groove 4125. Therefore, when the beauty head 030 and the main body 010 are assembled, the outlet and the inlet of the air pump 510 are connected to the beauty head 030, so that negative pressure can be formed in the negative pressure groove 4111 through the inlet of the air pump 510, and gas can be discharged between the beauty head 030 and the inner wall of the accommodating chamber 100a. Moreover, when the user holds the housing 100 and uses the beauty instrument 001, the user mainly observes the beauty head 030 of the beauty instrument 001, and rarely observes the tail cover part 131 of the beauty instrument 001. The exhaust groove 4125 guides the gas to be discharged through the gap between the beauty head 030 and the inner wall of the assembly groove 212a, which is convenient for the user to observe whether the exhaust groove 4125 of the beauty instrument 001 is blocked, so as to maintain the normal operation of the beauty instrument 001.

[0442] When the beauty head 030 is inserted into the assembly groove 212a, the first electrical connector 240 of the main body 010 is also connected to the second electrical connector 470 of the beauty head 030, thereby realizing the electrical connection between the beauty head 030 and the main body 010. The RF electrode 420 is electrically connected to the second electrical connector 470 via the head circuit board 460. The main body 010 can provide electrical energy to the beauty head 030 and control the RF current output of the RF electrode 420.

[0443] The beauty instrument 001 provided in the present application can be installed into the assembly groove 212a through the beauty head 030, so as to realize the connection between the air pump outlet and the air pump inlet and the beauty head 030, and realize the electrical connection between the beauty head 030 and the main body 010, which is convenient for the user to operate.

[0444] Furthermore, the main body 010 can also identify the type of the beauty head 030. The beauty head 030 includes multiple types. For example, the beauty head 030 can be a first type module including two RF electrodes 420, or a second type module including four RF electrodes 420. When the beauty head 030 is installed in the assembly slot 212a, the main body 010 can identify the type of the beauty head 030, such as whether it is a first type module or a second type module, so that the main body 010 can control the beauty head 030 in a targeted manner. The number of RF electrodes 420 on the beauty head 030 can also be other, for example, five RF electrodes 420 are located at the five corners of a pentagon, and each time the two RF electrodes 420 are turned on, an RF current is formed.

[0445] In this way, the present application provides a plurality of beauty heads 030 which are selectively installed on the main body 010, so that the user can choose different beauty heads 030 for use according to needs; and the present application can also identify different types of beauty heads 030 and perform corresponding control, thereby improving the use flexibility of the beauty instrument 001.

[0446] Furthermore, the main body 010 includes a sensor, and the beauty head 030 includes a sensing element. The sensor is used to identify the type of the beauty head 030. In some embodiments, the sensor may be a Hall sensor, and the sensing element may be a magnetic element; different types of beauty heads 030 are provided with different types of magnetic elements, and the type of the beauty head 030 may be determined by sensing the magnetic element of the beauty head 030 through the Hall sensor. In other embodiments, the sensor may also be an identification circuit embedded or integrated into the main control board 310 or the main circuit board 250, and the type of the beauty head 030 may be determined by identifying the type of the second electrical connection element 470. In other embodiments, the sensor may also be an NFC sensor, and the sensing element may be an NFC coil; the NFC sensor may sense the type of the NFC coil, and thus determine the type of the beauty head 030.

[0447] Fig.29A schematic diagram of the structure of a gas path switching module 520 in one embodiment of the present application is shown.

[0448] Please refer to Figure 20 to Figure 22 and Fig.29 The sensor includes at least three sensing points, and the sensing element is electrically in contact with at least two of the sensing points, so as to conduct the two sensing points electrically in contact with the sensing element. In this way, different types of beauty heads 030 can be identified by sensing different positions or numbers of sensing points, and this method has low cost and occupies less space.

[0449] Further, one end of at least three first electrical connectors 240 may form a sensing point, and each first electrical connector 240 may form a sensing point. At least two second electrical connectors 470 are configured as a part of the sensing element, that is, the sensing element includes at least part of the second electrical connectors 470, wherein "at least part of the second electrical connectors 470" indicates a part in quantity, that is, only a few of the plurality of second electrical connectors 470 may be used to form the sensing element. In this way, it can be understood that the first electrical connector 240 and the second electrical connector 470 can be classified, that is, some of the first electrical connectors 240 and the corresponding second electrical connectors 470 are used to realize the electrical connection and control with the RF electrode 420 or the first temperature sensor 430 or the second temperature sensor 450, and some of the first electrical connectors 240 and the corresponding second electrical connectors 470 are used to realize the type identification of the beauty head 030; and some of the first electrical connectors 240 and the second electrical connectors 470 can be made to have multiple functions, that is, the first electrical connector 240 and the corresponding second electrical connector 470 that realize the electrical connection with the RF electrode 420 or the first temperature sensor 430 or the second temperature sensor 450 are also used to realize the type identification of the beauty head 030. Both methods only need to change the number of the first electrical connectors 240 and the second electrical connectors 470, and are simple to manufacture and low in cost.

[0450] Further, the connection contacts 464 of the head circuit board 460 include conduction contacts and circuit break contacts (i.e., the fourth type of electrical contacts). Some of the second electrical connectors 470 are in contact with the conduction contacts, and some of the second electrical connectors 470 are in contact with the circuit break contacts. It can be understood that when a second electrical connector 470 is in contact with the conduction contact, the second electrical connector 470 forms a conduction needle 470a and is electrically connected to the head circuit board 460, and at least two second electrical connectors 470 are configured as conduction needles 470a. When a second electrical connector 470 is in contact with the circuit break contact, the second electrical connector 470 is a false second electrical connector, which forms a circuit break needle 470b and is non-electrically connected to the head circuit board 460. The first electrical connector 240 contacted by the circuit break needle 470b is also non-electrically connected to the head circuit board 460. The disconnect pin 470 b does not transmit an electrical signal between the header circuit board 460 and the body circuit board 250 .

[0451] Specifically, the main circuit board 250 or the main control board 310 is provided with an identification circuit connected to the first electrical connector 240. Different types of beauty heads 030 include different numbers of conduction pins 470a and break pins 470b and / or located at different positions. When different types of beauty heads 030 are installed on the main body 010, the identification circuit will generate different electrical signals, thereby identifying different beauty heads 030.

[0452] In other words, when the main circuit board 250 applies a high level to all the first electrical connectors 240, feedback is received from the head circuit board 460 so that the circuit board can determine whether the second electrical connector 470 belongs to a conduction pin 470a or a disconnection pin 470b. After the circuit board determines the types of all the second electrical connectors 470, the type of the beauty head 030 can be further determined. For example, if four second electrical connectors 470 in the first type module are disconnection pins 470b, and the other second electrical connectors 470 are conduction pins 470a. When the main circuit board 250 determines that there are four second electrical connectors 470 in the head circuit board 460, the beauty head 030 is determined to be a first type module. If two second electrical connectors 470 in the second type module are disconnection pins 470b, and the other second electrical connectors 470 are conduction pins 470a. When the main circuit board 250 determines that there are two second electrical connectors 470 in the head circuit board 460, the beauty head 030 is determined to be a second type module. For another example, if two second electrical connectors 470 in the first type module are disconnect pins 470b, and the two disconnect pins 470b are arranged adjacent to each other, and the other second electrical connectors 470 are conduction pins 470a. When the main circuit board 250 determines that the head circuit board 460 has only two disconnect pins 470b, and the two disconnect pins 470b are arranged adjacent to each other, then the beauty head 030 is determined to be a first type module. If two second electrical connectors 470 in the second type module are disconnect pins 470b, and a conduction pin 470a is arranged between the two disconnect pins 470b, and the other second electrical connectors 470 are conduction pins 470a. When the main circuit board 250 determines that the head circuit board 460 has only two disconnect pins 470b, and a conduction pin 470a is arranged between the two disconnect pins 470b, then the beauty head 030 is determined to be a second type module.

[0453] Specifically, the mounting shell 410 and the second electrical connector 470 are integrally injection molded.

[0454] It is understood that in other embodiments, the dummy second electrical connector (i.e., the disconnect pin 470b) may not be provided, and in this case, the molds of the mounting shells 410 of different types of beauty heads 030 will be different. That is, in this embodiment, by providing the dummy second electrical connector, the molds of the mounting shells 410 of different types of beauty heads 030 can be different, thereby reducing the production cost.

[0455] It is understandable that the disconnect pin 470b can be used in other ways to non-electrically connect the head circuit board 460 and the first electrical connector 240. For example, an insulating layer is coated on the surface of the disconnect pin 470b, while an insulating layer is not coated on the surface of the conductive pin 470a. For example, an insulating layer is coated on the surface of the first needle section 471 or the second needle section 472 of the disconnect pin 470b.

[0456] By providing a fake second electrical connector, different types of beauty heads 030 can have substantially the same arrangement of second electrical connectors 470. When producing beauty heads 030, different types of beauty heads 030 can have the same number of second electrical connectors 470, so that different types of beauty heads 030 can be produced using the same set of production molds, thereby saving production costs.

[0457] The conducting pins 470a and the disconnecting pins 470b in the second electrical connector 470 can be placed in different raw material boxes during the production process, so that the production equipment can take materials from the corresponding raw material boxes. Alternatively, different types of head circuit boards 460 are placed in different raw material boxes, and the production equipment takes out head circuit boards 460 corresponding to different types of beauty heads 030 from different raw material boxes to complete the production and assembly of different types of beauty heads 030. Alternatively, after the beauty heads 030 are produced, the second electrical connector 470 is coated with an insulating layer so that the corresponding second electrical connector 470 forms the disconnecting pins 470b.

[0458] Furthermore, there are different resistances between any two of the at least three sensing points. Thus, when any two sensing points are connected by the two conducting pins 470a, the resistance between the two sensing points can be short-circuited, so that the identification circuit in the main body 010 can generate different electrical signals according to the short-circuit conditions of different resistances to identify different beauty heads 030.

[0459] like Fig.29 As shown, specifically, when the beauty head 030 is connected to the main body 010, the two conducting pins 470a connect the sensing points formed by the two first electrical connectors 240 and conduct to form a loop, and the resistance between the two first electrical connectors 240 is short-circuited by the two conducting pins 470a and the circuit in the head circuit board 460, so that the main body 010 senses the current characteristics, thereby determining the type of the beauty head 030. When the position of the conducting pin 470a on the beauty head 030 changes, the main body 010 can sense different current characteristics, thereby identifying different types of beauty heads 030.

[0460] It can be understood that the induction element, i.e., the conduction needle 470a formed by the second electrical connection element 470, can also simultaneously conduct the three induction points formed by the first electrical connection elements 240 to form a corresponding resistance component, and sense different current characteristics through the main body 010, thereby identifying different types of beauty heads 030. Optionally, the current characteristic can be resistance, voltage or current.

[0461] When the user assembles the beauty head 030 to the main body 010, the main body 010 identifies the type of the beauty head 030 and can provide a control form corresponding to the type of the beauty head 030 for the user to choose, which can improve the user's usage experience.

[0462] It can be understood that in the beauty instrument 001 provided in the present application, the beauty head 030 can also be applied to the straight-plate-shaped main body 010. In the straight-plate-shaped main body 010, the head shell 110 is no longer tilted relative to the front shell 130 and the rear shell 120 along the first tilt direction U. The entire shell 100 extends along the first direction X. When the user uses the straight-plate-shaped beauty instrument 001, the wrist can be tilted to adapt to the angle between the skin and the beauty instrument 001.

[0463] It can be understood that in the above-mentioned embodiment in which the beauty head 030 and the main body 010 are detachable, multiple RF electrodes 420, the mounting shell 410, etc. form a RF component, wherein the mounting shell 410 is the RF shell. In this part of the embodiment, the multiple RF electrodes 420 can be installed on the skin-facing plate 011a indirectly through the mounting shell 410, etc., and the RF shell can be detachably installed on the skin-facing plate 011a.

[0464] Fig.30 An exploded schematic diagram of a beauty instrument 001 in another embodiment of the present application is shown. Fig.31 A cross-sectional view of a beauty instrument 001 in another embodiment of the present application is shown.

[0465] like Fig.30 and Fig.31 As shown, the beauty instrument 001 includes a housing 100 and a radio frequency component. The housing 100 includes a first half shell, a second half shell and a head shell 110. The first half shell is a rear shell 120, and the second half shell is a front shell 130. One end of the first half shell has a bending portion 121 that is bent and tilted toward a side close to the second half shell and is arranged in a first tilt direction U. The bending portion 121 can adapt to the head shell 110 so as to assemble the head shell 110, the front shell 130 and the rear shell 120. The head shell 110, the front shell 130 and the rear shell 120 are assembled to form the housing 100. When a user uses the beauty instrument 001, the head shell 110 of the beauty instrument 001 faces the user's skin.

[0466] In some embodiments, the head shell 110 is used to form the beauty head 030, the skin facing plate 011a is a skin contact plate, and the plurality of radio frequency electrodes 420 are exposedly mounted on the skin facing plate 011a.

[0467] In this part of the embodiment, further, the beauty instrument 001 also includes a cold compress component 900, which is installed on the head shell 110, and the cold compress component 900 includes a cold compress 910 and a cooling sheet 930. Among them, the cold compress 910 is exposedly installed on the skin-facing plate 011a, and the cooling sheet 930 is arranged in the head shell 110. The cooling sheet 930 is thermally connected to the cold compress 910, so that the heat of the cold compress 910 can be conducted to the cooling sheet 930, and the cooling sheet 930 absorbs heat to keep the temperature of the cold compress 910 at a low level to achieve cold compress on the skin, and even achieve a freezing point body sensation.

[0468] In some embodiments, at least three RF electrodes 420 are selectively provided at intervals along a preset direction. The preset direction may be a second inclined direction V. At least one cold compress 910 is provided between any two adjacent RF electrodes 420. When a radio frequency current is generated between the two RF electrodes 420, the skin between the two RF electrodes 420 is subjected to current stimulation beauty treatment, and the cold compress 910 can simultaneously apply cold compress to the skin, thereby improving the user experience and reducing the user's burning sensation; and more importantly, when the RF electrode 420 releases radio frequency energy, the skin covered by the RF electrode 420 has a higher temperature due to the energy blessing of the RF electrode 420. Although the cold compress 910 is provided between the two RF electrodes 420, the area covered by the RF electrode 420 will be cold-compressed, but it is obvious that the skin between the two RF electrodes 420 is better cold-compressed, so that a cold compress effect of alternating hot and cold can be formed in the end, thereby improving the beauty effect.

[0469] This beauty instrument 001 can beautify the user's skin through the radio frequency electrode 420, and the tilted setting of the head shell 110 makes the radio frequency electrode 420 tilted in the first direction X. When the user holds the beauty instrument 001, the radio frequency electrode 420 and the cold compress 910 can fit the user's skin more easily. The head shell 110 is provided with an assembly notch 11314, which can also facilitate the demolding of the head shell 110 after molding. The bending portion 121 roughly protrudes from the rear shell 120, and the head shell 110 is connected to the bending portion 121 and the front shell 130. The assembly notch 11314 of the head shell 110 is matched and connected with the bending portion 121. The bending portion 121 roughly protrudes from the rear shell 120, which means that the bending portion 121 extends from the rear shell 120 as a whole toward the head shell 110, and the front shell 130 does not directly cooperate with the bending portion 121, so that after the front shell 130 and the rear shell 120 are connected, the bending portion 121 roughly protrudes from the rear shell 120.

[0470] It can be understood that the beauty instrument 001 with the detachable beauty head 030 and the main body 010 can be designed as a portable radio frequency beauty instrument, which combines the radio frequency component and the gas source component 500 on a handheld shell to achieve miniaturization and portability of radio frequency beauty. In the above embodiment, the installation shell 410 of the beauty head 030, the outer shell 100 of the main body 010 and the connecting inner shell 210 form a handheld shell, that is, a protective shell. In this way, by assembling the RF components (RF electrode 420, RF circuit board 810, etc.) onto the handheld shell, the miniaturization and portability of the RF beauty instrument can be achieved, and by providing a negative pressure groove 4111 and an air source component 500 used in conjunction with the negative pressure groove 4111 on the handheld shell, when the RF beauty instrument is working, the skin can be sucked into the negative pressure groove 4111 through the negative pressure groove 4111, and then a RF current can be emitted to the skin after the suction through the RF electrode 420, so that the RF current can penetrate the skin sucked into the negative pressure groove 4111, thereby increasing the injection depth of the RF energy and improving the beauty effect.

[0471] It can be understood that in the above embodiment, in order to facilitate improving the assembly efficiency, the beauty head 030 and the main body 010 are designed to be detachable structures, but in other embodiments, the beauty head 030 and the main body 010 of the portable radio frequency beauty instrument can also be designed as non-detachable or difficult to detach structures. In this case, the corresponding detachable related structures can be cancelled, such as canceling the first electrical connector 240 and the second electrical connector 470, canceling one of the first airflow connection part 232 and the second airflow connection part 4114, canceling at least one of the head circuit board 460 and the main body circuit board 250, canceling the connection inner shell 210, etc., which are all adaptively changed structures, such as designing the handheld shell as 30 and Fig.31 The form of the housing 100 in the illustrated embodiment will not be described in detail herein.

[0472] It can be understood that in some embodiments, the handheld shell is the protective shell.

[0473] The above description is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the disclosure scope of the present application.
