Description

Technical Field

[0001] This invention belongs to the field of hair comb technology, and particularly relates to a plasma hair comb. Background Technology

[0002] Low-temperature plasma is a non-equilibrium plasma with an electron temperature much greater than an ion temperature. Due to its high electron density and electron energy, high concentration of active components, and gas temperature close to ambient temperature, it has been widely used in recent years in fields such as air disinfection, promoting skin wound healing, and environmental protection.

[0003] Head lice infestation is a contagious skin disease caused by head lice that infest the hair and scalp. Head lice bites can cause varying degrees of itching and rashes.

[0004] Currently, conventional methods mainly include applying insecticides and scraping with a fine-toothed comb. However, traditional medications can lead to drug resistance and skin irritation; traditional fine-toothed combs only physically remove parasites, which is inefficient. Currently available hairbrushes with negative ion functions are not very effective at killing head lice and other parasites. Summary of the Invention

[0005] The purpose of this invention is to provide a plasma hair comb that addresses the problems in the prior art.

[0006] The embodiments of the present invention are implemented as follows:

[0007] A plasma hair comb includes a discharge unit, a control unit, and a housing. The discharge unit is mounted at one end of the housing, and the control unit is mounted inside the housing.

[0008] The discharge unit includes a high-voltage electrode, a grounding electrode, and a high-voltage power supply. The high-voltage power supply is installed in the housing. The high-voltage electrode and the grounding electrode are installed on the surface of one end of the housing. The high-voltage electrode is electrically connected to the negative high-voltage ionized air of the high-voltage power supply to form discharge plasma. The grounding electrode is electrically connected to the ground electrode of the high-voltage power supply. There is a first distance D1 between the high-voltage electrode and the grounding electrode. In the use state, there is a second distance D2 between the high-voltage electrode and the scalp. The first distance D1 is smaller than the second distance D2. The first length L1 of the high-voltage electrode is smaller than the second length L2 of the grounding electrode.

[0009] The control unit includes a main control board and a lithium battery. The input terminal of the high-voltage power supply is electrically connected to the main control board, and the lithium battery is electrically connected to the main control board.

[0010] Preferably, the high-voltage electrode is made of conductive material and has multiple tip discharge sections; the grounding electrode is made of conductive plastic and serves as the comb teeth for combing hair. The root of the grounding electrode is fixed to the housing, and in use, the tip of the grounding electrode is attached to the scalp surface.

[0011] Preferably, the difference between the first spacing D1 and the second spacing D2 is in the range of 2-4, the first spacing D1 is 8-12mm, and the difference between the first length L1 and the second length L2 is at least 6mm.

[0012] Preferably, the housing is composed of a lower housing and an upper housing, and the surface of the lower housing is provided with an electrode groove, in which high-voltage electrodes and grounding electrodes are installed in parallel and spaced apart.

[0013] Preferably, an electrode plate is installed on the lower housing, one end of the high-voltage electrode and the grounding electrode are embedded in the mounting groove of the electrode plate, a battery bracket is installed between the lower housing and the upper housing, and the lithium battery is fixedly installed on the battery bracket.

[0014] Preferably, the surface of the upper housing is provided with multiple hollow windows, and a display screen, a button, and an indicator light guide are installed in the multiple hollow windows. The display screen, the button, and the indicator light guide are all electrically connected to the main control board.

[0015] Preferably, a USB charging port and a fan are installed on the lower housing, the output end of the lithium battery is electrically connected to the USB charging port, and the fan is electrically connected to the main control board.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The present invention has high safety: by setting a distance difference of D1 < D2 and a capture structure in which the length of the high voltage electrode L1 is less than the length of the ground electrode L2, the main discharge path is guided to the grounded conductive plastic, and the scalp is in a region with a weak electric field, thus avoiding the stinging sensation and burn risk of high voltage directly acting on the human body.

[0018] (2) The insecticidal effect of the present invention is good: negative high voltage corona discharge is used to generate high concentration of ozone and active nitrogen oxides in the D1 gap, which can effectively oxidize adult head lice and eggshells, solving the problem of unsatisfactory effect or drug resistance and irritation of existing solutions;

[0019] (3) Zero static electricity experience in the embodiment of the present invention: grounded conductive plastic is used as comb teeth, which neutralizes the positive charge generated by hair friction in real time during the combing process, and captures the negative ions generated by discharge, so that the hair strands remain smooth and not frizzy;

[0020] (4) The present invention has a compact structure: the electrodes are arranged in parallel intervals, and the ground electrode is used as the comb teeth, which is ergonomic and easy to clean. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0027] In one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown:

[0028] A plasma hair comb includes a discharge unit 1, a control unit 2, and a housing 3. The discharge unit 1 is mounted at one end of the housing 3, and the control unit 2 is mounted inside the housing 3.

[0029] The discharge unit 1 includes a high-voltage electrode 11, a ground electrode 12, and a high-voltage power supply 13. The high-voltage power supply 13 is installed in the housing 3. The high-voltage electrode 11 and the ground electrode 12 are installed on the surface of one end of the housing 3. The high-voltage electrode 11 is electrically connected to the negative high-voltage ionized air of the high-voltage power supply 13 to form discharge plasma. The ground electrode 12 is electrically connected to the ground electrode of the high-voltage power supply 13. There is a first distance D1 between the high-voltage electrode 11 and the ground electrode 12. In the use state, there is a second distance D2 between the high-voltage electrode 11 and the scalp. The first distance D1 is smaller than the second distance D2. The first length L1 of the high-voltage electrode 11 is smaller than the second length L2 of the ground electrode 12.

[0030] The control unit 2 includes a main control board 21 and a lithium battery 22. The input terminal of the high-voltage power supply 13 is electrically connected to the main control board 21, and the lithium battery 22 is electrically connected to the main control board 21.

[0031] In one embodiment of the present invention, a high-voltage electrode 11, a ground electrode 12, and a high-voltage power supply 13 constitute a discharge unit 1. The high-voltage power supply 13 is installed inside a housing 3. The high-voltage electrode 11 and the ground electrode 12 are installed on the surface of one end of the housing 3. The high-voltage electrode 11 is electrically connected to the negative high-voltage ionized air of the high-voltage power supply 13 to form a discharge plasma. The ground electrode 12 is electrically connected to the ground electrode of the high-voltage power supply 13. There is a first gap D1 between the high-voltage electrode 11 and the ground electrode 12. In the use state, there is a second gap D2 between the high-voltage electrode 11 and the scalp. The first gap D1 is smaller than the second gap D2. Because the first gap D1 is smaller than the second gap D2, it ensures... The electric field strength between the high-voltage electrode 11 and the ground electrode 12 is greater than that between the high-voltage electrode 11 and the scalp. Therefore, the corona discharge is only formed between the high-voltage electrode 11 and the ground electrode 12. A large number of charged particles generated are constrained by the electric field within the first gap D1 and are captured or neutralized by the conductivity of the ground electrode 12. Only a small number of charged particles diffuse to the scalp surface with the ion wind, ensuring the safety of the scalp side. In addition, the first length L1 of the high-voltage electrode 11 is less than the second length L2 of the ground electrode 12. The control unit 2 includes a main control board 21 and a lithium battery 22. The input terminal of the high-voltage power supply 13 is electrically connected to the main control board 21, and the lithium battery 22 is electrically connected to the main control board 21.

[0032] In yet another embodiment of the invention, such as Figure 1 , Figure 2 and Figure 3 As shown:

[0033] The high-voltage electrode 11 is made of conductive material and has multiple tip discharge sections; the ground electrode 12 is made of conductive plastic and serves as a comb for combing hair. The root of the ground electrode 12 is fixed to the housing 3, and in use, the tip of the ground electrode 12 is attached to the scalp surface.

[0034] The difference between the first spacing D1 and the second spacing D2 is in the range of 2-4, the first spacing D1 is 8-12mm, and the difference between the first length L1 and the second length L2 is at least 6mm.

[0035] The housing 3 is composed of a lower housing 31 and an upper housing 32. The surface of the lower housing 31 is provided with an electrode groove, in which a high-voltage electrode 11 and a grounding electrode 12 are installed in parallel and spaced apart.

[0036] An electrode plate 35 is installed on the lower housing 31. One end of the high voltage electrode 11 and the ground electrode 12 are embedded in the mounting groove of the electrode plate 35. A battery bracket 36 is installed between the lower housing 31 and the upper housing 32. The lithium battery 22 is fixedly installed on the battery bracket 36.

[0037] The surface of the upper housing 32 is provided with multiple hollow windows, and a display screen 23, a button 33 and an indicator light guide column 34 are installed in the multiple hollow windows. The display screen 23, the button 33 and the indicator light guide column 34 are all electrically connected to the main control board 21.

[0038] A USB charging port 24 and a fan 25 are installed on the lower housing 31. The output end of the lithium battery 22 is electrically connected to the USB charging port 24, and the fan 25 is electrically connected to the main control board 21.

[0039] In one embodiment of the present invention, the high-voltage electrode 11 is made of a conductive material, such as stainless steel or titanium alloy, and has multiple pointed discharge sections, such as serrated or needle-shaped sections, and is electrically connected to the negative high-voltage ionized air of the high-voltage power supply 13 to form discharge plasma; the ground electrode 12 is made of conductive plastic and serves as the comb teeth for combing hair. Its root is fixed to the lower housing 31 of the housing 3, and its tip is attached to the scalp surface, and it is electrically connected to the ground electrode of the high-voltage power supply 13. There is a first gap D1 between the high-voltage electrode 11 and the ground electrode 12. In use, there is a second gap D2 between the high-voltage electrode 11 and the scalp. It is necessary to ensure that the first gap D1 is smaller than the second gap D2, and the difference between the first gap D1 and the second gap D2 is in the range of 2-4. The first gap D1 is preferably 8-12 mm. In addition, the first length L1 of the high-voltage electrode 11 is smaller than the second length L2 of the ground electrode 12, and the difference between the first length L1 and the second length L2 is less than 10 mm. The distance is less than 6mm. Since the first gap D1 is smaller than the second gap D2, and the difference between the first gap D1 and the second gap D2 is in the range of 2-4, on the one hand, the electric field strength between the high-voltage electrode 11 and the ground electrode 12 is greater than the electric field strength between the high-voltage electrode 11 and the scalp. Therefore, the corona discharge is only formed between the high-voltage electrode 11 and the ground electrode 12. The large number of charged particles generated are constrained by the electric field within the first gap D1 and are captured or neutralized by the conductivity of the ground electrode 12. Only a small number of charged particles diffuse to the scalp surface with the ion wind, ensuring the safety of the scalp side. On the other hand, the difference between the first gap D1 and the second gap D2 is in the range of 2-4, which avoids the attenuation of active substances due to the excessive distance between the high-voltage electrode and the scalp, thus affecting the effect of use. At the same time, the first gap D1 is preferably 8-12mm, which can avoid the risk of applying too high voltage due to the excessively large discharge gap, and also prevent arcing caused by the gap being too small.

[0040] In one embodiment of the present invention, the control unit 2 includes a main control board 21 and a lithium battery 22. The input terminal of the high-voltage power supply 13 is electrically connected to the main control board 21, and the lithium battery 22 is electrically connected to the main control board 21 to supply power to the product. The housing 3 is composed of a lower housing 31 and an upper housing 32. The high-voltage electrode 11 and the ground electrode 12 pass through the mounting groove of the lower housing 31 of the housing 3, and an electrode pressure plate 35 is mounted on the lower housing 31. The electrode pressure plate 35 is also provided with a mounting groove. One end of the high-voltage electrode 11 and the ground electrode 12 are embedded into the mounting groove of the electrode pressure plate 35, thereby fixing the high-voltage electrode 11 and the ground electrode 12 securely. A battery bracket 36 is installed between the upper housing 31 and the upper housing 32, and the battery bracket 36 is fixedly connected to the electrode pressure plate 35. The lithium battery 22 is fixedly installed on the battery bracket 36. The surface of the upper housing 32 is provided with multiple hollow windows, and a display screen 23, a button 33 and an indicator light guide column 34 are installed in the multiple hollow windows. The button 33 and the indicator light guide column 34 are electrically connected to the main control board 21. The display screen 23 is soldered to the main control board 21. A USB charging port 24 and a fan 25 are installed on the lower housing 31. The output end of the lithium battery 22 is electrically connected to the USB charging port 24, and the fan 25 is used for heat dissipation and is electrically connected to the main control board 21.

[0041] In one embodiment of the present invention, the high-voltage power supply 13 outputs DC power of -3kV to -5kV or pulsed DC or AC power of 20kHz to 50kHz, and its input terminal is electrically connected to the main control board 21.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
