Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a plasma hair growth comb. Background Art

[0002] The plasma hair growth comb acts on the scalp through plasma, thereby increasing the absorption rate of drugs by the scalp tissue. It can also play a role in sterilization and anti-inflammation, effectively relieve the oily secretion of sebaceous glands, reduce symptoms such as scalp itching, and thus improve the health of the scalp.

[0003] The comb teeth of an existing plasma hair growth comb usually include a plasma generator and an isolation sleeve. One end of the plasma generator is electrically connected to a circuit board inside the hair growth comb, and the other end extends to the outside of the hair growth comb. The isolation sleeve is wrapped around the entire periphery of the plasma generator, thereby isolating the plasma generator to prevent the plasma generator from causing damage to the user's scalp. However, the provision of the isolation sleeve will also weaken the ionization energy output by the plasma generator to the scalp, weaken the effect of plasma on the scalp, and thus easily affect the therapeutic effect of the plasma hair growth comb on the scalp. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a plasma hair growth comb, which can reduce the weakening effect of the isolation sleeve on the ionization energy output to the scalp by the plasma generating module, thereby better improving the health of the scalp.

[0005] According to an embodiment of the present invention, the plasma hair growth comb comprises: a shell having an installation cavity, wherein a main control board is installed in the installation cavity; a plasma generating assembly comprising a PCB board, an electric wire and an isolating sleeve, wherein the electric wire is electrically connected to the main control board and extends upward to the outside of the shell, the PCB board is arranged at the upper end of the electric wire and is electrically connected to the electric wire, a plasma generating module is arranged on the outer surface of the PCB board, and the isolating sleeve is installed on the shell and sleeved on the outer periphery of the electric wire; wherein a first clearance hole is opened at the upper end of the isolating sleeve, the periphery of the first clearance hole abuts against the outer surface of the PCB board, and the plasma generating module is located in the first clearance hole and has a spacing with the upper end of the isolating sleeve.

[0006] The plasma hair growth comb according to the embodiment of the present invention has at least the following beneficial effects:

[0007] In the plasma hair growth comb of the embodiment of the present invention, by setting the PCB board provided with the plasma generating module at the upper end of the electric wire, the plasma can be output from the upper end of the electric wire.

[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0038] Reference Figures 1 to 9 According to an embodiment of the present invention, a plasma hair growth comb is provided, which includes a housing 100 and a plasma generating assembly 200. The housing 100 has an installation cavity, in which a main control board 130 is installed. The plasma generating assembly 200 includes a PCB board 210, an electric wire 220, and an isolation sleeve 230. The electric wire 220 is electrically connected to the main control board 130 and extends upward to the outside of the housing 100. The PCB board 210 is arranged at the upper end of the electric wire 220 and is electrically connected to the electric wire 220. A plasma generating module is arranged on the outer surface of the PCB board 210. The isolation sleeve 230 is installed on the housing 100 and sleeved on the outer periphery of the electric wire 220. A first clearance hole 231 is opened at the upper end of the isolation sleeve 230, and the periphery of the first clearance hole 231 abuts against the outer surface of the PCB board 210. The plasma generating module is located in the first clearance hole 231 and has a spacing with the upper end of the isolation sleeve 230.

[0039] In the plasma hair growth comb of the embodiment of the present invention, by setting the PCB board 210 provided with the plasma generation module at the upper end of the electric conductor 220, plasma can be output from the upper end of the electric conductor 220. By setting the isolation sleeve 230 on the outer periphery of the electric conductor 220, the electric conductor 220 can be isolated and protected. By setting the first clearance hole 231 on the outer end of the isolation sleeve 230, the periphery of the first clearance hole 231 abuts against the outer surface of the PCB board 210, the PCB board 210 can be confined inside the isolation sleeve 230, and the PCB board 210 is prevented from escaping from the isolation sleeve 230, thereby enhancing the structural stability of the plasma generation assembly 200. In addition, the plasma generating module is located in the first clearance hole 231 and has a gap with the upper end of the isolation sleeve 230, so that the first clearance hole 231 can make way for the plasma generating module, so that the plasma output by the plasma generating module can pass through the first clearance hole 231 and directly act on the scalp, thereby reducing the weakening effect of the isolation sleeve 230 on the ionization energy output by the plasma generating module to the scalp, thereby improving the therapeutic effect of the plasma hair growth comb on the scalp and better improving the health of the scalp. And because there is a gap between the plasma generating module and the upper end of the isolation sleeve 230, there is a gap between the plasma generating module and the scalp when the plasma hair growth comb is in use, thereby reducing the risk of the plasma generating module directly contacting the scalp and causing damage to the scalp.

[0040] It can be understood that the above-mentioned plasma generating module is located in the first clearance hole 231 and has a distance between it and the upper end of the isolation sleeve 230. Specifically, the thickness of the plasma generating module is less than the depth of the first clearance hole 231, that is, the thickness of the plasma generating module is less than the thickness of the upper end of the isolation sleeve 230. Therefore, a distance can be formed between the plasma generating module and the upper end of the isolation sleeve 230 to avoid the plasma generating module directly contacting the scalp and causing damage to the scalp during use.

[0041] Reference Figures 1 to 9 In some embodiments, a mounting plate 300 connected to the housing 100 is installed in the mounting cavity, and the isolation sleeve 230 is fixedly installed on the mounting plate 300. The mounting plate 300 is provided with a first mounting hole 310 corresponding to the plasma generating assembly 200, and the inner wall of the first mounting hole 310 is provided with a first limiting portion 311 protruding inwardly; the lower end of the isolation sleeve 230 is provided with a first abutting portion 232 protruding outwardly relative to the isolation sleeve 230, and the isolation sleeve 230 can be passed through the first mounting hole 310 from bottom to top and fixedly installed on the mounting plate 300, and the first abutting portion 232 abuts against the first limiting portion 311 upwardly.

[0042] By adopting the above structure and arranging the mounting plate 300 in the mounting cavity, the installation and fixation of the isolation sleeve 230 can be facilitated. Specifically, by opening a first mounting hole 310 on the mounting plate 300, a first limiting portion 311 is provided on the inner wall of the first mounting hole 310, and at the same time, a first abutting portion 232 protruding outward is provided at the lower end of the isolation sleeve 230. Therefore, during installation, the electrical conductor 220, the PCB board 210 and other structures can be installed to the isolation sleeve 230 first, and then the isolation sleeve 230 can be inserted into the first mounting hole 310 from bottom to top, and the first abutting portion 232 of the isolation sleeve 230 can be upwardly abutted against the first limiting portion 311 in the first mounting hole 310, and then the isolation sleeve 230 can be fixedly installed on the mounting plate 300. The installation process is very simple and convenient, and the first limiting portion 311 can limit the isolation sleeve 230 to prevent the isolation sleeve 230 from moving upward relative to the shell 100 and escaping from the first mounting hole 310, thereby making the installation of the isolation sleeve 230 more firm and stable.

[0043] Reference Figures 1 to 9 In some embodiments, a fixing member 320 corresponding to the isolation sleeve 230 is installed on the lower side of the mounting plate 300. The fixing member 320 abuts against the lower end of the isolation sleeve 230 and confines the isolation sleeve 230 in the mounting hole. The fixing member 320 also has a makeshift groove 321131 for the power supply wire 220 to pass through.

[0044] By adopting the above structure, a fixing member 320 is provided on the lower side of the mounting plate 300, thereby facilitating the fixed connection between the isolation sleeve 230 and the mounting plate 300. The installation is to first insert the isolation sleeve 230 into the first mounting hole 310 from bottom to top, and make the first abutting portion 232 abut against the first limiting portion 311 upward, and then directly fix the fixing member 320 on the lower side of the mounting plate 300, so that the fixing plate can abut against the lower end of the isolation sleeve 230 and limit the isolation sleeve 230 in the first mounting hole 310 of the mounting plate 300, thereby preventing the isolation sleeve 230 from moving downward and disengaging from the first mounting hole 310, thereby making the installation of the isolation sleeve 230 more firm and stable. By providing a clearance groove 321131 on the fixing member 320 for the power supply wire 220 to pass through, the power supply wire 220 can be led out from the isolation sleeve 230 to be electrically connected to the main control board 130 in the installation cavity, thereby facilitating the control of the operation of the plasma generating module on the PCB board 210.

[0045] It is understandable that, referring to Figures 1 to 9The fixing member 320 can be a component that is independent of the isolation sleeve 230. When installing, the isolation sleeve 230 is first inserted into the first mounting hole 310 of the mounting plate 300 and the first abutting portion 232 is upwardly abutted against the first limiting portion 311, and then the fixing member 320 is installed, and the fixing member 320 is upwardly abutted against the lower end of the isolation sleeve 230 and fixedly installed on the mounting plate 300, thereby facilitating the maintenance or replacement of the isolation sleeve 230 and the fixing member 320. Of course, in addition to this, the fixing member 320 can also be a component that is integrally formed with the isolation sleeve 230. When installing, it is only necessary to first insert the isolation sleeve 230 into the first mounting hole 310 of the mounting plate 300 and the first abutting portion 232 is upwardly abutted against the first limiting portion 311, and at the same time, the fixing member 320 is upwardly abutted against the lower end of the isolation sleeve 230, and then the fixing member 320 is fixedly installed on the mounting plate 300, thereby making the installation and fixation of the isolation sleeve 230 simpler and more convenient.

[0046] It is understandable that the fixing installation between the fixing member 320 and the mounting plate 300 can specifically use fasteners such as screws and studs. In addition, snap-fit ​​structures such as buckles and hooks or other mounting structures can also be used, and the present invention does not make specific limitations on this.

[0047] Reference Figures 1 to 9 In some embodiments, the isolation sleeve 230 is provided with an isolation groove 233 in which the power supply wire 220 is inserted, and a first mounting groove 234 is provided at the lower end of the isolation sleeve 230. The isolation groove 233 penetrates the inner top wall of the first mounting groove 234 and is connected to the first mounting groove 234. The cross-sectional area of ​​the first mounting groove 234 is larger than the cross-sectional area of ​​the isolation groove 233. The outer periphery of the power supply wire 220 is covered with an insulating sleeve 240. The insulating sleeve 240 and the power supply wire 220 have an interference fit. The lower end of the insulating sleeve 240 is provided with a second abutting portion 241 protruding outward. The insulating sleeve 240 is inserted into the isolation groove 233 from bottom to top, and the upper surface of the second abutting portion 241 can abut against the inner top wall of the first mounting groove 234. The fixing member 320 abuts against the lower end of the insulating sleeve 240 and confines the insulating sleeve 240 in the isolation groove 233.

[0048] By adopting the above structure, the insulating sleeve 240 is wrapped around the outer periphery of the electric wire 220 and is interference fit with the electric wire 220, thereby better protecting the electric wire 220, and also facilitating the installation and fixation of the electric wire 220, so that the structure of the plasma generating assembly 200 is more stable. By opening an isolation groove 233 in the isolation sleeve 230 to facilitate the wrapping of the electric wire 220, the first clearance hole 231 for making way for the plasma generating module can be directly opened on the top wall of the isolation groove 233. By opening a first mounting groove 234 connected to the isolation groove 233 at the lower end of the isolation sleeve 230, the isolation groove 233 passes through the top wall of the first mounting groove 234, and the cross-sectional area of ​​the first mounting groove 234 is larger than the cross-sectional area of ​​the isolation groove 233, so that the inner top wall of the first mounting groove 234 can be arranged around the outer periphery of the isolation groove 233 and form a step portion. During installation, the isolation sleeve 230 can be inserted into the isolation groove 233 from bottom to top, and the second abutting portion 241 of the insulating outer wall can directly abut upward against the inner top wall of the first mounting groove 234, and then abut against the lower end of the insulating sleeve 240 through the fixing member 320, so that the fixing member 320 can be confined in the isolation groove 233 to prevent the fixing member 320 from being separated from the isolation groove 233, thereby making the structure of the plasma generating assembly 200 more compact and the installation more firm and stable.

[0049] It can be understood that the electrical conductor 220 may specifically include two electrical conductors and an insulating layer covering the two electrical conductors.

[0050] Reference Figures 1 to 9 In some embodiments, the first mounting groove 234 is formed on the lower surface of the first abutting portion 232 , and the fixing member 320 abuts against the lower surface of the first abutting portion 232 .

[0051] By adopting the above structure, the first abutment portion 232 is directly set at the lower end of the isolation sleeve 230. Therefore, when installing the isolation sleeve 230, it is only necessary to insert the isolation sleeve 230 into the first mounting hole 310 from bottom to top, and make the first abutment portion 232 abut against the first limiting portion 311, and then install the fixing member 320 and abut the fixing member 320 against the first abutment portion 232. Therefore, the first abutment portion 232 can be limited between the first limiting portion 311 and the fixing member 320, and then the isolation sleeve 230 can be limited to prevent the isolation sleeve 230 from being separated from the installation of the mounting plate 300.

[0052] It is understandable that, in some embodiments, the first abutment portion 232 and the isolation sleeve 230 can be set as an integrally formed structure. In this case, the first abutment portion 232 is set at the lower end of the isolation sleeve 230, which is conducive to the production and processing of the isolation sleeve 230. In addition, in other embodiments, the isolation sleeve 230 and the first abutment portion 232 can also adopt a split structure, and when installing, it is only necessary to install the first abutment portion 232 to the lower end of the isolation sleeve 230.

[0053] Reference Figures 1 to 3 In some embodiments, the shell 100 includes an upper shell 110 and a lower shell 120, the mounting plate 300 is installed between the upper shell 110 and the lower shell 120, the main control board 130 is installed on the mounting plate 300 and is located between the mounting plate 300 and the lower shell 120, and the isolation sleeve 230 is passed through the upper shell 110 and extends to the outside of the upper shell 110.

[0054] By adopting the above structure, the housing 100 is divided into an upper housing 110 and a lower housing 120, and the installation cavity is formed by the upper housing 110 and the lower housing 120. The installation plate 300 is installed between the upper housing 110 and the lower housing 120, thereby making the structure of the plasma hair growth comb more compact and stable. The space between the installation plate 300 and the lower housing 120 can be used to install the main control board 130, and the space between the installation plate 300 and the upper housing 110 can facilitate the installation of the plasma generating assembly 200, thereby facilitating the reasonable use of the space in the installation cavity inside the housing 100 and the reasonable layout of the components.

[0055] Reference Figures 1 to 3 It can be understood that, in some embodiments, the mounting plate 300 can be installed between the upper shell 110 and the lower shell 120 by fasteners that are sequentially installed on the upper shell 110, the mounting plate 300, and the lower shell 120, wherein the number of fasteners can be multiple, and the fasteners can specifically be threaded structures such as bolts and screws. Alternatively, the upper shell 110 and the mounting plate 300 can be connected together by at least one fastener, and then the mounting plate 300 and the lower shell 120 can be installed together by at least one fastener, thereby also realizing the installation connection between the upper shell 110, the mounting plate 300, and the lower shell 120. In addition, the upper shell 110, the mounting plate 300, and the lower shell 120 can also be installed together by snap-fit ​​structures such as snap hooks or other connecting structures, which is not specifically limited by the present invention.

[0056] It can be understood that in order to facilitate the installation connection between the upper shell 110 and the lower shell 120, a first positioning portion can be set on the lower shell 120, and a second positioning portion can be set on the upper shell 110, wherein the first positioning portion is provided with a positioning groove adapted to the second positioning portion, the mounting plate 300 is provided with a positioning hole adapted to the first positioning portion, and the second positioning portion is passed through the positioning hole and inserted into the positioning groove.

[0057] By adopting the above structure, the installation between the upper shell 110, the mounting plate 300 and the lower shell 120 can be positioned, making the installation between the upper shell 110, the mounting plate 300 and the lower shell 120 simpler and more convenient. Specifically, during installation, the positioning column of the lower shell 120 can be inserted into the positioning hole of the mounting plate 300, thereby achieving the positioning between the positioning plate and the lower shell 120, and then the positioning groove on the upper shell 110 and the corresponding positioning column are plugged into each other, thereby achieving the positioning between the upper shell 110, the mounting plate 300 and the lower shell 120, and then facilitating the fixed installation of the upper shell 110, the mounting plate 300 and the lower shell 120.

[0058] Reference Figures 1 to 3 In some embodiments, the lower shell 120 is provided with a lower mounting column 121 extending upward, and the main control board 130 is provided with a clearance groove 321131 adapted to the lower mounting column 121, and the lower mounting column 121 can be inserted into the corresponding clearance groove 321131 and fixedly connected to the mounting plate 300.

[0059] By adopting the above structure, the setting of the lower mounting column 121 can not only realize the fixed connection between the lower shell 120 and the mounting plate 300, but also realize the positioning installation of the main control board 130, and the structure is simple and the installation is convenient.

[0060] It can be understood that the clearance groove 321131 opened on the main control board 130 can be an open groove structure located at the edge of the main control board 130, or it can be a through hole structure opened inside the main control board 130. The present invention does not make specific limitations on this. It only requires that the clearance groove 321131 can make way for the corresponding lower mounting column 121.

[0061] It is understandable that the fixed connection between the lower mounting column 121 and the mounting plate 300 can be achieved by fasteners such as screws and bolts.

[0062] Reference Figures 1 to 3In some embodiments, the upper shell 110 is provided with an upper mounting column 111 corresponding to the lower mounting column 121. The upper mounting column 111 and the lower mounting column 121 can cooperate to clamp the mounting plate 300, and during installation, screws, bolts and other fasteners can be sequentially installed on the upper mounting column 111, the mounting plate 300 and the lower mounting column 121 to achieve fixed installation between the upper shell 110, the mounting plate 300 and the lower shell 120.

[0063] Reference Figures 1 to 10 In some embodiments, the plasma hair growth comb further includes at least one set of comb tooth assembly 400, the comb tooth assembly 400 includes a mounting seat 410 and a plurality of comb teeth mounted on the mounting seat 410, the mounting seat 410 is provided with a second clearance hole 411 corresponding to the isolation sleeve 230, wherein the mounting seat 410 can be detachably mounted on the upper shell 110, and the isolation sleeve 230 is passed through the corresponding second clearance hole 411.
