In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one".

[0042] In this document, unless otherwise explicitly stated and limited, the terms "mounting", "connected", "connection" should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0044] In one embodiment, a portable plasma beauty instrument is described, which is provided with a roller mechanism 4 on the side of the ceramic sheet 2 away from the beauty instrument body 1, so that the electric charge generated by the high-voltage module 3 ionizing the air on the side of the ceramic sheet 2 away from the beauty instrument body 1 moves to the roller assembly, reducing the intensity of the electric charge when the roller mechanism 4 acts on the user, so that the electric charge gently acts on the user, to improve the comfort and enthusiasm of the user using the plasma beauty instrument.

[0045] Specifically, referring to the drawings in the specification Figures 1 to 5 A portable plasma beauty instrument includes a beauty instrument body, a ceramic sheet 2, a high-voltage module 3 and a roller mechanism 4, wherein the ceramic sheet 2 is arranged on the outside of the beauty instrument body 1, the high-voltage module 3 is arranged in the beauty instrument body 1 and is electrically connected with the ceramic sheet 2, and the ceramic sheet 2 can generate electric charge by ionizing air on the side of the ceramic sheet 2 away from the beauty instrument body 1 under the action of high-voltage pulse electricity of the high-voltage module 3. The roller mechanism 4 is rotatably arranged on the side of the ceramic sheet 2 away from the beauty instrument body 1 and does not contact the side of the ceramic sheet 2 away from the beauty instrument body 1, and the portable plasma beauty instrument moves relative to the skin through the roller mechanism 4. In addition, the roller mechanism 4 has a conductive assembly 42, and part of the electric charge generated by ionizing air on the side of the ceramic sheet 2 away from the beauty instrument body 1 can be conducted and adsorbed on the conductive assembly 42 after moving a distance, so that the roller mechanism 4 can have a beautifying effect on the skin when moving relative to the skin.

[0046] Correspondingly, when the high-voltage module 3 ionizes air on the side of the ceramic sheet 2 away from the beauty instrument body 1, the oxygen in the air can also be ionized and decomposed into ozone and the like, and the electric charge and ozone can kill bacteria and clean the skin when in contact with the skin, promote skin regeneration, and thus achieve the purpose of improving the skin.

[0047] It can be understood that in the prior art, the plasma beauty instrument is often provided with only one ceramic sheet, and the electric charge generated by ionization of the high-voltage module directly contacts the skin of the user through the ceramic sheet, so that the electric charge directly acts on the skin, the energy is high, and the generated heat is also more, which can cause harm to the human body. In the embodiment, the ceramic sheet 2 and the roller mechanism 4 are provided, so that the electric charge generated by ionization on the side of the ceramic sheet 2 away from the beauty instrument main body 1 needs to move a distance before being adsorbed on the conductive assembly 42. Part of the electric charge is adsorbed by the conductive assembly 42, which does not cause the electric charge to be too dispersed to affect the beauty effect, and increases the moving distance and time of the electric charge, thereby reducing the strength of the electric charge on the roller mechanism 4, the energy is more gentle, thereby improving the safety of the beauty instrument and reducing the discomfort of the user when using the plasma beauty instrument.

[0048] In one embodiment, referring to the drawings of the specification Figure 1 and Figure 2 , the embodiment further illustrates the beauty instrument main body 1. The beauty instrument main body 1 includes a clamping assembly 12 and a shell 11, and the high-voltage module 3 is arranged in the shell 11. One end of the clamping assembly 12 is connected and fixed with the shell 11, and the other end of the clamping assembly 12 is arranged as a mounting end, which is arranged on the inner side (inside) of the shell 11. The ceramic sheet 2 and the roller mechanism 4 are arranged on the mounting end, and the roller mechanism 4 is detachably connected with the mounting end.

[0049] Further, the shell 11 includes a main cover 112 and a handle 111 arranged below the main cover 112, the high-voltage module 3 is arranged in the main cover 112, and the end of the clamping assembly 12 away from the mounting end is connected and fixed with the main cover 112. Correspondingly, the high-voltage module 3 channel wire is electrically connected with the external power supply, and the high-voltage module 3 is powered by the external power supply to generate high-voltage pulse electricity. In use, the user can hold the handle to drive the main cover 112 and the roller mechanism 4 to move. The handle 111 can be provided with a groove for the user to hold, so as to facilitate the user to hold the plasma beauty instrument. The handle 111 and the main cover 112 can be connected and fixed.

[0050] In one embodiment, referring to the drawings of the specification Figure 2 , Figure 3 and Figure 5The clamping assembly 12 comprises a locking member 121, a mounting member 122 and two clamping arms 123. The two clamping arms 123 are oppositely arranged on the two sides of the mounting member 122. One end of each clamping arm 123 is rotatably connected to the mounting member 122 through a connecting shaft as a rotating shaft. The other end of each clamping arm 123 is also provided with a fixing shaft 1231 on the side close to the other clamping arm 123. The two fixing shafts 1231 are respectively inserted into two mounting grooves 416 provided on the two ends of the roller mechanism 4, so that the roller mechanism 4 is rotatably arranged between the two clamping arms 123 through the fixing shafts 1231 and cannot be separated from the fixing shafts 1231 under the action of the locking member 121 (the locking member 121 is in clamping cooperation with the clamping arms 123 and the mounting member 122 to fix the clamping arms 123 on the mounting member 122). The roller mechanism 4 is located outside the shell 11 and is arranged relative to the ceramic sheet 2. After the clamping cooperation between the locking member 121 and the clamping arms 123 and the mounting member 122 is released, the clamping arms 123 rotate relative to the mounting member 122, and the end of the clamping arm 123 provided with the fixing shaft 1231 moves away from the mounting member 122, so that the fixing shaft on the clamping arm 123 is separated from the roller mechanism 4, and then the roller mechanism 4 can be removed.

[0051] The ceramic sheet 2 is arranged at one end of the mounting member 122. The other end of the mounting member 122 (the end not provided with the ceramic sheet 2) is fixedly arranged in the shell 11. The end of the mounting member 122 provided with the ceramic sheet 2 extends out of the shell 11, and the roller mechanism 4 is located on the side of the ceramic sheet 2 away from the mounting member 122. In addition, the locking member 121 is suitable for clamping cooperation with the clamping arms 123 and the mounting member 122 to fix the clamping arms 123 on the mounting member 122. When the portable plasma beauty instrument is used for beauty, the locking member 121 fixes the clamping arms 123 on the mounting member 122 to facilitate stable and reliable rotation of the roller mechanism 4. When different roller mechanisms 4 need to be replaced, the locking member 121 releases the connection and fixation of the mounting member 122 and the clamping arms 123, rotates the clamping arms 123, separates the fixing shaft on the other end of the clamping arm 123 from the roller mechanism 4, and separates the roller mechanism 4 from the clamping assembly 12.

[0052] It should be noted that the side wall of the main shell 112 is also provided with a notch groove through which the mounting member 122 passes. There is a gap between the clamping arm 123 and the notch groove to ensure that the clamping arm 123 can rotate relative to the mounting member 122. In addition, the ceramic sheet 2 and the high-voltage module 3 are connected through a cable. The mounting member 122 is also provided with a cable passage penetrating the mounting member 122. The cable passes through the cable passage to connect the ceramic sheet 2 and the high-voltage module 3.

[0053] The locking member 121 can be arranged on the nut, and the clamping arm 123 and the mounting member 122 are provided with threaded holes matched with the nut. In use, the clamping arm 123 and the mounting member 122 are fixed and installed through the screwing cooperation of the locking member 121 (nut) and the threaded hole, and the clamping arm 123 is rotated away from the mounting member 122 through the separation of the locking member 121 (nut) and the threaded hole, so as to realize the separation of the roller mechanism 4 from the clamping assembly 12. Preferably, a sealing ring is arranged on the outer side of the nut to prevent the nut from slipping during rotation.

[0054] Preferably, an elastic member in a compressed state is further arranged between the clamping arm 123 and the mounting member 122. After the locking member 121 (nut) is removed and the clamping arm 123 and the mounting member 122 are released from the limiting, the clamping arm 123 swings under the restoring force of the elastic member, that is, the end of the clamping arm 123 provided with the fixed shaft 1231 swings away from the mounting member 122, so as to separate the roller mechanism 4 from the clamping assembly 12.

[0055] It can be understood that the roller mechanism 4 is arranged on the side of the ceramic sheet 2 away from the mounting member 122, and the ceramic sheet 2 and the roller mechanism 4 are not in contact. Generally, the distance between the two is set to 0.7 mm, so that the electric charge generated by the high-voltage pulse current generated by the high-voltage module 3 after ionizing the air on the side of the ceramic sheet 2 away from the beauty instrument main body 1 is partially conducted on the roller mechanism 4 after passing through the air interval of 0.7 mm, and then the roller mechanism 4 generates a beauty effect when acting on the skin.

[0056] Preferably, the clamping arm 123 can be rotated left and right relative to the mounting member 122 in addition to rotating (up and down relative to the mounting member 122) the end of the roller mechanism 4 provided with the fixed shaft 1231 relative to the mounting member 122 to remove the roller mechanism 4, so that the roller mechanism 4 is staggered with the ceramic sheet 2, and the electric charge generated by the high-voltage module 3 on the side of the ceramic sheet 2 away from the beauty instrument main body 1 only needs to be directly acted on the skin of the user through the ceramic sheet 2.

[0057] In one embodiment, referring to the drawings Figure 1 , Figure 2 and Figure 4 , the roller mechanism 4 further includes a roller body 41, and a conductive assembly 42 is sleeved on the outer side of the roller body 41. The roller body 41 is rotatably arranged on the clamping assembly 12 through the fixed shaft on the clamping arm 123, so that the roller body 41 is rotatably arranged on the side of the ceramic sheet 2 away from the beauty instrument main body 1. The conductive assembly 42 is used to adsorb the electric charge generated by the high-voltage module 3, that is, part of the electric charge generated by the high-voltage module 3 can be adsorbed on the roller mechanism 4, so as to reduce the energy at the roller mechanism 4 and acting on the skin, thereby reducing the discomfort of the user in use.

[0058] In addition, in order to facilitate the installation and fixation of the conductive assembly 42 on the roller body 41, a limiting groove is formed on the roller body 41, the limiting groove is arranged along the circumference of the roller body 41, the conductive assembly 42 is sleeved on the outer side of the roller body 41 and arranged in the limiting groove. In addition, the conductive assembly 42 is arranged protruding from the roller body 41, so that when the roller mechanism 4 moves along the skin of the user, the conductive assembly 42 is in contact with the skin of the user, so that the electric charge can better act on the skin.

[0059] Specifically, referring to the drawings of the specification Figure 4 The embodiment further illustrates the roller body 41. The roller body 41 has a first part 411 and a second part 412 arranged oppositely. The first part 411 is provided with a first protruding part 413, and the first protruding part 413 is located on the side of the first part 411 close to the second part 412. Correspondingly, the second part 412 is provided with a second protruding part 414, and the second protruding part 414 is located on the side of the second part 412 close to the first part 411. An inner groove 415 is arranged on the second protruding part 424, and the first protruding part 413 and the second protruding part 414 are connected and fixed by the inner groove 415 of the first protruding part 413 and the second protruding part 414. In this way, a limiting groove matched with the conductive assembly 42 is formed between the first protruding part 413 and the second protruding part 414.

[0060] In addition, two mounting grooves 416 are formed on the first part 411 and the second part 412 respectively. The first protruding part 413 can be interference fit with the inner groove 415, or external threads can be arranged on the outer side of the first protruding part 413, and the inner groove 415 is provided with internal threads matched with the external threads, so that the first protruding part 413 and the second protruding part 414 are connected by threads. Of course, in actual production and application, there are many ways to realize the connection of the two, and the structure of the roller body 41 also has many forms, which will not be described one by one here, and all are within the protection scope of the utility model.

[0061] In one embodiment, referring to the drawings of the specification Figure 4 The embodiment provides a specific structure of the conductive assembly 42. The conductive assembly 42 includes a plurality of metal rings 43 and insulating sleeve rings 44 arranged alternately. The metal rings 43 and the insulating sleeve rings 44 are arranged alternately, and the metal rings 43 are arranged protruding from the roller body 41. After the current of the high-voltage module 3 ionizes the air on the side of the ceramic sheet 2 away from the beauty instrument main body 1, part of the electric charge moves a distance and acts on the plurality of metal rings 43, so that the electric charge is dispersed on the plurality of metal rings 43. As a preferred embodiment, the metal rings 43 and the insulating sleeve rings 44 are arranged at equal distances alternately, so that the electric charge is evenly distributed on the roller mechanism 4, preventing the local electric charge energy from being too high.

[0062] Of course, the conductive assembly 42 can also only include metal rollers, which are sleeved outside the limiting grooves and protrude from the roller body 41.

[0063] In another embodiment, the conductive assembly 42 includes a plurality of groups of metal pieces, each group of metal pieces including a plurality of metal needles arranged along the circumference of the roller body 41, the metal needles protruding from the roller body 41, so that the roller mechanism 4 can form needle holes on the skin when moving through the metal needles, facilitating better interaction of the electric charge with the skin and improving the effect of the plasma beauty instrument. As a preferred, the plurality of groups of metal pieces are equally spaced, and the plurality of metal needles of each group of metal pieces are uniformly distributed along the circumference of the roller body 41, so that the electric charge is uniformly distributed on the roller mechanism 4, preventing local electric charge energy from being too high.

[0064] Generally, the number of metal rings 43 is set to 6, and the number of insulating sleeve rings 44 is set to 5. The number of metal rings is set to 6, and the number of insulating sleeve rings is set to 5. The material of the insulating sleeve ring 44 and the insulating sleeve ring is resin or the like. Of course, the number of metal rings 43 can be set according to the actual situation of the roller body 41, and the conductive assembly 42 can be clamped in the limiting groove by adjusting the distance between the first part 411 and the second part 412. This will not be described one by one, and it is within the protection scope of the present application.

[0065] In addition, the metal needles can be of different specifications, such as the length of the metal needles being D, 0.2mm≤D≤3mm. The length of the metal needles can be set according to actual needs, and the general length is 0.15mm, 0.25mm, 0.3mm, 0.5mm, 0.75mm, 1mm, 1.5mm, 2mm, 2.5mm and 3mm, etc.

[0066] It should be noted that the above embodiments can be freely combined as needed. The above description is only the preferred embodiments of the present application. It should be noted that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should be considered as the protection scope of the present application.
