[0058] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0061] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if the meaning of "and / or" appearing in the full text is to include three parallel schemes, taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0062] The present invention provides a plasma generating system.

[0063] In the embodiment of the present invention, Figure 1 and Fig.14 As shown, the plasma generating system comprises a plasma generator 10 and a charging stand 20 used in conjunction with the plasma generator 10. The charging stand 20 is used to support the plasma generator 10 and charge the plasma generator 10.

[0064] When the plasma generator 10 is not needed, the plasma generator 10 can be plugged into the charging stand 20, so that the plasma generator 10 can be stably placed on a desktop or the like to prevent the plasma generator 10 from rolling off the desktop or the like, and when the plasma generator 10 needs to be charged, the charging stand 20 electrically connected to the power supply can charge the plasma generator 10. When the plasma generator 10 needs to be used, the plasma generator 10 can be removed from the charging stand 20.

[0065] When the plasma generator 10 is used, when the plasma generator 10 is close to the user's scalp, the plasma generator 10 can ionize the air between the user's scalp and the plasma generator 10 to generate plasma. The plasma acts on the user's scalp and can improve the health of the scalp.

[0066] In this embodiment, if Figure 1-Figure 4 As shown, the plasma generator 10 includes a housing 300, a plasma generating assembly 400 and a first battery 500. The plasma generating assembly 400 is disposed on the housing 300. The first battery 500 is disposed in the housing 300.

[0067] The housing 300 is provided with a switch button 302a and a first charging contact 302b.

[0068] The switch button 302a is used to connect or disconnect the plasma generating assembly 400 and the first battery 500. When the plasma generating assembly 400 and the first battery 500 are connected, the plasma generator 10 can work, and when the plasma generating assembly 400 and the first battery 500 are disconnected, the plasma generator 10 does not work.

[0069] The first charging contact 302 b is electrically connected to the first battery 500 . When the first battery 500 is connected to the power supply through the first charging contact 302 b , the power supply can charge the first battery 500 .

[0070] In this embodiment, the housing 300 has a charging end 302. The switch button 302a and the first charging contact 302b are both located at the charging end 302. In this way, when the charging end 302 of the housing 300 of the plasma generator 10 is inserted into the charging base 20, the first charging contact 302b of the charging end 302 is electrically connected to the second charging contact 212 in the charging base 20. At this time, the charging base 20 electrically connected to the power supply can charge the first battery 500. Since the switch button 302a and the first charging contact 302b are both located at the charging end 302, the charging base 20 can shield the switch button 302a when the plasma generator 10 is charged and when the plasma generator 10 is not needed, thereby preventing the plasma generator 10 from being turned on due to misoperation of the switch button 302a, thereby improving the safety of the plasma generator 10. For example, when charging, if the switch button 302a is accidentally triggered to turn on the plasma generator 10, at this time, if the plasma generator 10 is close to the user's eyes, the air between the eyes and the plasma generator 10 will be ionized, and the generated plasma will impact the eyes, causing eye injury.

[0071] In this embodiment, the switch button 302a and the first charging contact 302b are both located on the end surface of the charging end 202. In this way, it is easier to shield the switch button 302a during charging. It can be understood that in other embodiments, at least one of the switch button 302a and the first charging contact 302b can also be on the circumferential wall surface of the charging end 202.

[0072] In this embodiment, the charging end 302 is provided with an avoidance hole 3022. The first charging contact 302b is received in the avoidance hole 3022. In this way, the protruding first charging contact 302b can be prevented from being damaged by scratches.

[0073] In this embodiment, the housing 300 includes a handle portion 310 and a working portion 320 connected to each other. The first battery 500 is located in the handle portion 310. The plasma generating assembly 400 is located on the working portion 320. The charging end 302 is an end of the handle portion 310 away from the working portion 320.

[0074] In this embodiment, the cross section of the handle portion 310 is oval, which is more convenient for the user to hold. In other embodiments, the cross section of the handle portion 310 may also be circular, square, or the like.

[0075] In this embodiment, in the arrangement direction of the handle portion 310 and the working portion 320 , the width of the working portion 320 is greater than or equal to the width of the handle portion 310 .

[0076] In this embodiment, if Figure 4-Figure 9 As shown, the plasma generating assembly 400 includes a mounting seat 410, a working electrode 420 and an isolation cap 430. The working portion 320 has an opening 320a. The mounting seat 410 closes the opening 320a. The mounting seat 410 is provided with a mounting through hole 410a. The working electrode 420 has a plug-in portion 422 and an outer protrusion 424 connected to the plug-in portion 422. The plug-in portion 422 is plugged into the mounting through hole 410a. One end of the plug-in portion 422 away from the outer protrusion 424 is used to be electrically connected to a power source. In this embodiment, the power source is the first battery 500. It can be understood that in other embodiments, when the first battery 500 is omitted, the working electrode 420 can be powered by connecting to the mains, and in this case, the power source is the mains. The outer protrusion 424 is located outside the mounting through hole 410a. The isolation cap 430 has an open end 432, and the isolation cap 430 is sleeved outside the outer protrusion 424 through the open end 432.

[0077] By providing the opening 320a, it is very convenient to assemble the mounting seat 410 on the working part 320, and it is convenient for the plug-in portion 422 of the working electrode 420 to be electrically connected to the power supply. By providing the mounting through hole 410a, it is very convenient for the plug-in portion 422 of the working electrode 420 to be assembled on the mounting seat 410. The outer protrusion 424 of the working electrode 420 is located outside the mounting through hole 410a, so that the outer protrusion 424 of the working electrode 420 protrudes outside the mounting seat 410, so that it is more convenient for the working electrode 420 to approach the user's scalp and other parts, for example, it is more convenient for the isolation cap 430 and the outer protrusion 424 of the working electrode 420 to form a comb for combing hair. The isolation cap 430 can isolate the outer protrusion 424 of the working electrode 420 to prevent the working electrode 420 from causing damage to the user's scalp and other parts when working.

[0078] In this embodiment, the mounting seat 410 is detachably connected to the working portion 320. In this way, it is very convenient to disassemble and assemble. Specifically, in this embodiment, the mounting seat 410 is buckled with the working portion 320 by a buckle.

[0079] In order to further improve the isolation effect of the working electrode 420, in this embodiment, as Figure 4-Figure 11As shown, the mounting seat 410 is an isolation seat 410. The isolation seat 410 is also provided with a mounting groove 410b surrounding the mounting through hole 410a. The outer protrusion 424 and the mounting groove 410b are located on the same side of the isolation seat 410. The isolation cap 430 is sleeved outside the outer protrusion 424 through the open end 432, and the open end 432 is plugged into the mounting groove 410b. Since the isolation cap 430 is sleeved outside the outer protrusion 424 through the open end 432, when the working electrode 420 is working, there is a risk that the ionization energy released by the working electrode 420 will leak out through the open end 432. By providing the mounting groove 410b, the open end 432 is plugged into the mounting groove 410b, so as to form an inner and outer two-layer isolation layer at the open end 432, thereby effectively preventing the ionization energy released by the working electrode 420 from leaking out through the open end 432, further improving the isolation effect of the working electrode 420, and making the plasma generator 10 have higher safety.

[0080] In some embodiments, Fig.12 As shown, the end surface of the open end 432 is in conflict with the isolation seat 410. In some embodiments, the open end 432 and the isolation seat 410 are sealed and fixed by glue 432a surrounding the open end 432. In some embodiments, the end surface of the open end 432 is in conflict with the isolation seat 410, and the open end 432 and the isolation seat 410 are sealed and fixed by glue 432a surrounding the open end 432. In this way, the ionization energy released by the working electrode 420 can be prevented from leaking through the open end 432 to a certain extent, further improving the isolation effect of the working electrode 420, so that the plasma generator 10 has higher safety.

[0081] In this embodiment, if Figure 4-Figure 9 As shown, the isolation seat 410 includes a mounting plate 412 and an isolation protrusion 414. The mounting plate 412 closes the opening 320a. The isolation protrusion 414 is protruded outside the side of the mounting plate 412 away from the opening 320a. The mounting through hole 410a passes through the mounting plate 412 and the isolation protrusion 414. The mounting groove 410b is located at one end of the isolation protrusion 414 away from the mounting plate 412. By providing the isolation protrusion 414, it is easier for the outer protrusion 424 of the working electrode 420 to protrude outside the isolation seat 410, so that it is easier for the working electrode 420 to approach the user's scalp and other parts, for example, it is easier for the isolation cap 430 and the outer protrusion 424 of the working electrode 420 to form a comb for combing hair.

[0082] In this embodiment, the material of the mounting plate 412 is the same as the material of the isolation protrusion 414. That is, the mounting plate 412 is an isolation plate. In this way, it is more conducive to isolating the working electrode 420. It can be understood that in other embodiments, the material of the mounting plate 412 can also be different from the material of the isolation protrusion 414.

[0083] In this embodiment, the material of the isolation seat 410 is polycarbonate, which has both an isolation effect and good light transmittance.

[0084] In this embodiment, the mounting plate 412 and the isolation protrusion 414 are integrally formed, so as to facilitate manufacturing.

[0085] In this embodiment, the isolation protrusion 414 has an inner isolation tube 4142. The mounting through hole 410a includes a hollow cavity of the inner isolation tube 4142. The mounting groove 410b surrounds the inner isolation tube 4142. One end of the inner isolation tube 4142 close to the outer protrusion 424 extends out of the mounting groove 410b. In this way, it is easier for the outer protrusion 424 of the working electrode 420 to protrude outside the isolation seat 410, so that it is easier for the working electrode 420 to approach the user's scalp and other parts. For example, it is easier for the isolation cap 430 and the outer protrusion 424 of the working electrode 420 to form comb teeth for combing hair. While ensuring that the working electrode 420 has a good isolation effect, the mass and volume of the isolation protrusion 414 can also be made smaller, which is more conducive to obtaining a plasma generator 10 with a smaller weight and volume.

[0086] In some embodiments, Fig.11 As shown, the isolation seat 410 has an inner isolation tube 4142. The inner isolation tube 4142 has a mounting through hole 410a. The mounting groove 410b surrounds the inner isolation tube 4142. Among them, one end of the inner isolation tube 4142 close to the outer protrusion 424 extends out of the mounting groove 410b. In this way, it is also easier for the outer protrusion 424 of the working electrode 420 to protrude out of the isolation seat 410, so that it is easier for the working electrode 420 to approach the user's scalp and other parts, for example, it is easier for the isolation cap 430 and the outer protrusion 424 of the working electrode 420 to form a comb for combing hair.

[0087] In this embodiment, if Figure 4-Figure 9 As shown, the outer diameter of the isolation protrusion 414 gradually decreases in the arrangement direction from the mounting plate 412 to the isolation protrusion 414. In this way, while preventing the ionization energy released by the working electrode 420 from leaking out through the open end 432, further improving the isolation effect of the working electrode 420, and making the plasma generator 10 more secure, the mass and volume of the isolation protrusion 414 can also be reduced, which is more conducive to obtaining a plasma generator 10 with a smaller weight and volume.

[0088] In this embodiment, the mounting through hole 410a has a connected plug section 410c and a transition section 410d, the inner diameter of the transition section 410d is larger than the inner diameter of the plug section 410c, and the transition section 410d is closer to the mounting plate 412 than the plug section 410c. One end of the plug section 422 close to the outer protrusion 424 is plugged into the plug section 410c. In this way, it is not only convenient for the working electrode 420 to be plugged into the mounting through hole 410a, but also convenient for the working electrode 420 to be electrically connected to the power supply at the side where the transition section 410d is located.

[0089] In this embodiment, the plug portion 422 is loosely matched with the plug section 410c. When manufacturing the plasma generator 10, after the working electrode 420 is plugged into the mounting through hole 410a, glue can be dispensed between the working electrode 420 and the inner wall of the mounting through hole 410a to firmly fix the working electrode 420.

[0090] In this embodiment, the outer diameter of the outer protrusion 424 is greater than the outer diameter of the plug-in portion 422. In this way, the outer protrusion 424 is conveniently located outside the mounting through hole 410a, thereby facilitating the positioning and assembly of the working electrode 420 and the mounting through hole 410a.

[0091] In this embodiment, the isolation cap 430 is gap-matched with the outer protrusion 424. In this way, it is very convenient to insert the outer protrusion 424 into the isolation cap 430. When manufacturing the plasma generator 10, after the working electrode 420 is inserted into the isolation cap 430, glue can be dispensed between the working electrode 420 and the inner wall of the isolation cap 430 to firmly fix the working electrode 420.

[0092] In this embodiment, the opening end 432 of the isolation cap 430 is in clearance with the inner peripheral wall of the mounting groove 410b. In this way, it is very convenient to insert the opening end 432 into the mounting groove 410b. When manufacturing the plasma generator 10, after the opening end 432 is inserted into the mounting groove 410b, glue can be applied between the opening end 432 and the inner peripheral wall of the mounting groove 410b to firmly fix the isolation cap 430.

[0093] In this embodiment, the end surface of the opening end 432 is in contact with (including in conflict with) the bottom of the mounting groove 410 b , so that the ionization energy released by the working electrode 420 can be better isolated.

[0094] In this embodiment, the diameter of the outer protrusion 424 is 2.8 mm-3.6 mm. In this way, it is very convenient for the outer protrusion 424 of the working electrode 420 to ionize and discharge. The diameter of the outer protrusion 424 can be 2.9 mm, 3.0 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm or 3.5 mm.

[0095] In this embodiment, the outer diameter of the isolation cap 430 is 4.0 mm-5.0 mm, and the wall thickness of the isolation cap 430 is 0.3 mm-1.5 mm. In this way, it is very convenient to isolate the discharge of the outer protrusion 424 of the working electrode 420. Among them, the outer diameter of the isolation cap 430 can be 4.1 mm, 4.2 mm, 4.3 mm, 4.4 mm, 4.5 mm, 4.6 mm, 4.7 mm, 4.8 mm or 4.9 mm. The wall thickness of the isolation cap 430 can be 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm or 1.4 mm.

[0096] Specifically, in this embodiment, the diameter of the outer protrusion 424 is 3.2 mm, the outer diameter of the isolation cap 430 is 4.5 mm, and the wall thickness of the isolation cap 430 is 0.6 mm.

[0097] In this embodiment, the end of the isolation cap 430 away from the opening end 432 is a flat end 434. In this way, the end of the isolation cap 430 away from the opening end 432 can have a relatively large ionization end surface, which is more conducive to ionizing the air between the end of the isolation cap 430 away from the opening end 432 and the user's scalp.

[0098] In some embodiments, Fig.13 and Fig.14 As shown, the end of the isolation cap 430 away from the open end 432 is a rounded end 436. In some embodiments, the end face of the rounded end 436 includes a convex arc working surface 4362. In some embodiments, the end face of the rounded end 436 includes a concave arc working surface. The convex arc working surface 436 can prevent the end face of the rounded end 436 from scratching the user's scalp. The user's scalp is roughly arc-shaped, and the concave arc working surface can make the end face of the rounded end 436 and the user's scalp roughly the same shape, so that the distance between the end face of the rounded end 436 and the user's scalp can be roughly the same everywhere, and the air between the end face of the rounded end 436 and the user's scalp can be ionized more evenly.

[0099] In this embodiment, the material of the isolation cap 430 is an insulating material. Specifically, in this embodiment, the material of the isolation cap 430 is ceramic. More specifically, in this embodiment, the material of the isolation cap 430 is zirconium oxide or aluminum oxide. In other embodiments, the material of the isolation cap 430 may also be Teflon.

[0100] In this embodiment, if Figure 4-Figure 9As shown, the mounting through hole 410a, the mounting groove 410b, the working electrode 420 and the isolation cap 430 are all multiple and are arranged one by one. That is, the multiple isolation protrusions 414, the working electrode 420 and the isolation cap 430 are all multiple and are arranged one by one. In this way, the plasma generator 10 can have a larger ionization area.

[0101] In this embodiment, a plurality of isolation caps 430 are disposed at intervals from each other. A plurality of isolation protrusions 414 are disposed at intervals from each other.

[0102] In this embodiment, the isolation seat 410 includes a connected mounting portion 416 and a light-transmitting portion 418. The mounting through hole 410a and the mounting groove 410b are located on the mounting portion 416. In this embodiment, the mounting plate 412 includes the mounting portion 416, and the light-transmitting portion 418 includes an isolation protrusion 414 and a portion of the mounting plate 412 corresponding to the isolation protrusion 414.

[0103] The plasma generator 10 further includes a light therapy component 600 located in the housing 300. The light therapy component 600 includes a first light source 610. In this embodiment, the first light source 610 is a laser light source. The first light source 610 is located on a side of the isolation seat 410 away from the isolation cap 430, and is arranged corresponding to the light-transmitting portion 418. In this way, the light emitted by the first light source 610 can irradiate the user's scalp through the light-transmitting portion 418, irradiate the user's scalp, stimulate cells, activate hair root cells, promote blood circulation, and then promote hair growth, prevent hair loss and baldness.

[0104] In this embodiment, there are multiple first light sources 610, which are distributed in the gaps between multiple isolation caps 430 and multiple isolation protrusions 414. In this way, the shielding of the first light sources 610 by the isolation caps 430 and the isolation protrusions 414 can be reduced.

[0105] In this embodiment, the light-transmitting portion 418 is provided with a avoiding groove 4182 at a position corresponding to the first light source 610 , so as to avoid the protruding first light source 610 and facilitate the light of the first light source 610 to pass through the isolation seat 410 .

[0106] In this embodiment, the plasma generator 10 further includes a vibration massage component 700 located in the housing 300. The vibration massage component 700 is used to drive the isolation seat 410 to vibrate. In this way, when the working electrode 420 is not working, the isolation cap 430 can be brought into contact with the user's scalp, and the vibration massage component 700 is turned on to make the isolation seat 410 vibrate, thereby achieving vibration massage of the user's scalp.

[0107] In this embodiment, the vibration massage component 700 , the first light source 610 and the working electrode 420 are all electrically connected to the first battery 500 , and the first battery 500 supplies power to the vibration massage component 700 , the first light source 610 and the working electrode 420 .

[0108] In this embodiment, the plasma generator 10 further includes a transformer 800 and a circuit board 900 located in the housing 300. The transformer 800, the vibration massage assembly 700, and the first light source 610 are electrically connected to the first battery 500 through the circuit board 900, and the transformer 800 is electrically connected to the plug-in portion 422 of the working electrode 420 through the circuit board 900. The transformer 800 can increase the voltage of the first battery 500 and provide a high voltage to the working electrode 420, so that the working electrode 420 can ionize the air between the user's scalp and the isolation cap 430 when working.

[0109] In this embodiment, the circuit board 900 is divided into two pieces, namely, a first circuit board 900a and a second circuit board 900b. The isolation seat 410, the first circuit board 900a and the second circuit board 900b are arranged in sequence, and the first circuit board 900a is electrically connected to the second circuit board 900b. The working electrode 420 and the first light source 610 are electrically connected to the first circuit board 900a, respectively, and the first battery 500, the vibration massage component 700 and the transformer 800 are electrically connected to the second circuit board 900b, respectively. The two circuit boards 900 are provided to facilitate the electrical connection of each component with the first battery 500.

[0110] In this embodiment, the first circuit board 900a is exposed from the opening 320a. The first circuit board 900a is provided with a plug hole 910 corresponding to the plug portion 422. The plug portion 422 is plugged into the plug hole 910, thereby realizing the electrical connection between the working electrode 420 and the first circuit board 900a. In this way, it is very convenient to electrically connect the working electrode 420 to the first circuit board 900a.

[0111] In this embodiment, the housing 300 includes a first housing 330 and a second housing 340. The first housing 330 and the second housing 340 are arranged along the arrangement direction of the isolation seat 410, the first circuit board 900a and the second circuit board 900b, and are detachably connected. The first housing 330 and the second housing 340 enclose a cavity for accommodating the first battery 500, the light therapy component 600, the vibration massage component 700, the transformer 800 and the circuit board 900. The opening 320a is located on the first housing 330.

[0112] In this embodiment, if Figure 4-Figure 9As shown, a conductive member 350 is provided on the handle portion 310 of the housing 300. The conductive member 350 is electrically connected to the plasma generating assembly 400. Specifically, in this embodiment, the conductive member 350 is electrically connected to the negative electrode of the first battery 500. In this way, the plasma generating assembly 400 (working electrode 420) is close to the user's scalp, and when the plasma generating assembly 400 (working electrode 420) is working, the plasma generating assembly 400 (working electrode 420) ionizes the air between the user's scalp and the plasma generating assembly 400 (working electrode 420 and / or isolation cap 430) to generate plasma. At this time, when the user touches the conductive member 350, a loop is formed between the plasma generating assembly 400 (working electrode 420 and / or isolation cap 430), plasma, human body, conductive member 350 and plasma generating assembly 400 (working electrode 420), which can increase the energy of the ionization energy output by the working electrode 420.

[0113] In this embodiment, the conductive member 350 is in the shape of a long strip. The length direction of the conductive member 350 is the same as the length direction of the handle portion 310. In this way, the user can touch the conductive member 350 when holding the handle portion 310 at different positions, which is more convenient for the user to use.

[0114] In this embodiment, the conductive member 350 is a long metal sheet, such as a metal copper sheet.

[0115] In this embodiment, the conductive member 350 is located at the junction of the first shell 330 and the second shell 340, that is, at the connection position between the first shell 330 and the second shell 340. In this way, the conductive member 350 is conveniently electrically connected to the first battery 500.

[0116] In some embodiments, there are multiple conductive members 350, and the multiple conductive members 350 are connected to each other. Among them, at least one conductive member 350 is electrically connected to the plasma generating assembly 400. Providing multiple conductive members 350 makes it easier for users to contact the conductive members 350.

[0117] In some embodiments, Fig.15 and Fig.16 As shown, the conductive member 350 includes a first conductive member 350 a and a second conductive member 350 b that are insulated from each other. The first conductive member 350 a and the second conductive member 350 b can be electrically connected by a user holding the handle portion 310 .

[0118] The plasma generator 10 further includes a detection module 360. The detection module 360 ​​is used to detect whether the first conductive member 350a and the second conductive member 350b are conductive. When the first conductive member 350a and the second conductive member 350b are conductive, the plasma generating assembly 400 works. When the first conductive member 350a and the second conductive member 350b are not conductive, the plasma generating assembly 400 does not work. That is, before the plasma generating assembly 400 works, the detection module 360 ​​first detects whether the first conductive member 350a and the second conductive member 350b are conductive by the user holding the handle 310. That is, the detection module 360 ​​first detects whether the user touches the first conductive member 350a and the second conductive member 350b at the same time. After the user touches the first conductive member 350a and the second conductive member 350b at the same time, the plasma generating assembly 400 works. In this way, the plasma generating assembly 400 can be prevented from malfunctioning and the user experience can be improved.

The fixed cover 220 is disposed on the charging base 210. The fixed cover 220 has a fixed cavity 220a for accommodating the charging end 202 of the plasma generator 10 (to be fixed). When the charging end 202 of the plasma generator 10 (to be fixed) is accommodated in the fixed cavity 220a, the charging stand 20 stably supports the plasma generator 10 (to be fixed), and the first charging contact 302b of the charging end 202 of the plasma generator 10 (to be fixed) conflicts with the second charging contact 212 of the charging stand 210. In this way, the charging stand 20 can effectively protect the plasma generator 10 (to be fixed) by preventing the plasma generator 10 (to be fixed) from rolling off a desktop or the like, and the charging stand 20 electrically connected to the power supply can also charge the plasma generator 10 (to be fixed).

[0121] In this embodiment, an exposed charging interface 214 is provided on the charging base 210, and the charging interface 214 is electrically connected to the second charging contact 212.

In this way, the charging base 20 can stably support the plasma generator 10 (the part to be fixed).

[0123] In this embodiment, the outer diameter of the fixing cover 220 gradually decreases in the arrangement direction from the charging base 210 to the fixing cover 220. In this way, it is not only convenient for the charging base 20 to stably support the plasma generator 10 (the part to be fixed), but also convenient for the user to identify the insertion end of the charging base 20, which has a foolproof effect.

[0124] In this embodiment, the shape of the fixing cavity 220a is the same as the shape of the charging end 202 of the plasma generator 10 (the part to be fixed).

It can be understood that in other embodiments, the fixed cover 220 and the charging base 210 can also be detachably connected by screwing.

[0127] In this embodiment, the charging base 210 has a concave escape groove 218. The shape of the escape groove 218 is the same as the end surface shape of the charging end 202 of the plasma generator 10 (the part to be fixed). In this way, the charging base 20 can stably support the plasma generator 10 (the part to be fixed).

[0128] In this embodiment, the second charging contact 212 is located at the bottom of the avoidance groove 218. In this way, it is easier to electrically connect the second charging contact 212 to the charging end 202 of the plasma generator 10 (the part to be fixed).

[0129] In some embodiments, Fig. 20 As shown, the bayonet 216 is located at the bottom of the avoidance groove 218. In some embodiments, as Fig.21 As shown, the latch 216 is located on the outer periphery of the avoidance groove 218 .

[0130] In this embodiment, if Figure 17-Figure 21As shown, the charging stand 20 also includes a second light source 230. The second light source 230 is arranged on the charging base 210 and is electrically connected to the charging interface 214. The fixed cover 220 is light-transmissive. The light emitted by the second light source 230 can pass through the fixed cover 220. Therefore, when the charging base 210 is electrically connected to the power supply through the charging interface 214, the second light source 230 is illuminated. At this time, the charging stand 20 can also play a lighting role and can be used as a desk lamp. In some embodiments, the charging stand 20 also includes a second battery, and the second battery is electrically connected to the second light source 230 to power the second light source 230. Therefore, when the charging base 210 is not electrically connected to the power supply, the second light source 230 can be illuminated by the second light source 230.

[0131] In this embodiment, the charging base 210 includes a base plate 210a, a third circuit board 210b and a base body 210c, the base body 210c is disposed on the base plate 210a, and the third circuit board 210b is sandwiched between the base body 210c and the base plate 210a. The second charging contact 212, the second light source 230 and the charging interface 214 are electrically connected to the third circuit board 210b respectively. Among them, the fixed cover 220 and the base body 210c are detachably connected. The avoidance groove 218 is located on the base body 210c. The second charging contact 212 and the second light source 230 are both exposed from the side of the base body 210c close to the fixed cover 220. The charging interface 214 is exposed from the peripheral side wall of the base body 210c.

[0132] In this embodiment, the charging base 210 further includes an anti-skid ring 210d. The anti-skid ring 210d is disposed on a side of the bottom plate 210a away from the base body 210c. The anti-skid ring 210d can be provided to allow the charging base 210 to stand stably on a desktop or the like.

[0133] In some embodiments, Fig. 20 As shown, the wall of the fixing cavity 220a is a hollow structure. In this way, the material cost of the charging stand 20 can be reduced while the charging stand 20 stably supports the plasma generator 10 (the part to be fixed).

[0134] In some embodiments, Fig.21 As shown, the wall of the fixing cavity 220a is a solid structure, so that the charging seat 20 can stably support the plasma generator 10 (the part to be fixed).
