Description

Hair Care Comb Technical Field

[0001] The invention relates to a hair care comb. Background Art

[0002] Existing combs only have the function of combing hair, but do not have the effect of relieving fatigue and relaxing nerves, and are unable to improve the user's hair loss condition, and have a single function. Summary of the Invention

[0003] The object of the present invention is to provide a hair care comb which promotes hair growth and maintains hair health by combining electronic muscle stimulation (EMS) technology and plasma technology.

[0004] The object of the present invention is achieved like this:

[0005] A hair care comb includes a housing, a comb tooth device, a control device, and a control circuit board. The comb tooth device includes a comb tooth base, an EMS microcurrent generator for generating EMS microcurrent, and a plasma generator for generating plasma. The EMS microcurrent generator includes a first circuit board and first comb teeth. The first circuit board is disposed on the comb tooth base, and the first comb teeth are disposed on the comb tooth base and connected to the first circuit board.

[0006] The plasma generator includes a second circuit board and second comb teeth, the second circuit board is arranged on the comb tooth base, the second comb teeth are arranged on the comb tooth base and connected to the second circuit board, the first comb teeth and the second comb teeth are spaced 2 mm to 10 mm apart, and a height difference is formed between the lower ends of the second comb teeth and the lower ends of the first comb teeth;

[0007] The control device is arranged on the housing, the control circuit board is arranged in the inner cavity of the housing, and the control device and the control circuit board are electrically connected;

[0008] The shell is provided with a comb device installation area, the comb device is arranged in the comb device installation area, the first circuit board and the second circuit board are electrically connected to the control circuit board respectively, and the control device controls the start and stop of the EMS microcurrent generator and the plasma generator through the control circuit board.

[0009] When using a hair care comb for hair care, the EMS microcurrent generator generates EMS microcurrent through the first comb teeth. The EMS microcurrent transmits a weak current through contact with the scalp to stimulate the scalp and hair follicles, promoting hair growth by increasing blood flow and stimulating scalp cells. The plasma generator excites ions in the air through the second comb teeth and releases energy, i.e., plasma. The plasma is used to stimulate scalp cells, improve blood circulation, promote hair growth, reduce dandruff, and improve hair quality. In addition, the first and second comb teeth are adjusted to an appropriate distance to avoid the risk of high-voltage discharge from the plasma generator due to excessive proximity, thereby improving safety and meeting the requirements for simultaneous operation of the EMS microcurrent generator and plasma generator. In addition, the first and second comb teeth are appropriately spaced to avoid sparse comb teeth and improve the combing effect of the hair care comb. In addition, a height difference is formed between the lower end of the second comb teeth and the lower end of the first comb teeth, which is conducive to controlling an appropriate discharge gap between the second comb teeth and the scalp.

[0010] The purpose of the present invention can also be solved by the following technical measures:

[0011] Furthermore, it also includes a flexible rubber pad, the comb tooth seat is spaced apart with mounting holes, the flexible rubber pad is provided with a boss at the position corresponding to the mounting hole, the boss has a plug-in hole, the flexible rubber pad is arranged on the comb tooth seat, the boss is inserted into the corresponding mounting hole and clamped, the first comb tooth is a conductive comb tooth, the first comb tooth is clamped in the plug-in hole, the head of the first comb tooth extends upward toward the outside of the plug-in hole and is electrically connected to the first circuit board, and the tail of the first comb tooth extends downward toward the outside of the plug-in hole.

[0012] The boss is a flexible colloid. When the boss is inserted into the mounting hole of the comb tooth seat, the boss will produce elastic deformation during the 360-degree swing, pushing up and pressing down process. Since the first comb teeth are hard conductive comb teeth, the first comb teeth are inserted into the plug-in hole of the boss and clamped. The first comb teeth have elastic function. When using the hair care comb to comb hair, the first comb teeth produce corresponding elastic changes according to the combing action during the combing process, avoiding the stiffness of the first comb teeth and improving the comfort of the user in combing hair.

[0013] Furthermore, the flexible rubber pad has connecting holes formed at positions corresponding to the mounting holes, and connecting ribs are provided at intervals on the outer wall of the boss. The boss is positioned within the connecting holes, and the connecting ribs are connected to the inner wall of the connecting hole to secure the boss within the connecting hole. When a user combs their hair with the hair-care comb, the first comb teeth are subjected to pressure and deflect. Since the first comb teeth are made of hard metal, connecting the first comb teeth to the boss of the flexible rubber pad imparts an elastic effect to the first comb teeth, preventing them from being stiff, and making combing with the hair-care comb more comfortable.

[0014] Furthermore, a retaining ring is provided near the head of the first comb tooth, and a clamping area is formed between the retaining ring and the head of the first comb tooth. The clamping area is placed in the plug-in hole, the head of the first comb tooth abuts against the upper port of the plug-in hole, and the retaining ring abuts against the lower port of the plug-in hole.

[0015] The clamping area of ​​the first comb teeth is placed in the plug hole, the head of the first comb teeth abuts against the upper end of the plug hole, and the retaining ring abuts against the lower end of the plug hole, so that the first comb teeth are installed more firmly.

[0016] Furthermore, it also includes an elastic conductor, the first circuit board is provided with a conductive contact corresponding to the first comb tooth position, one end of the elastic conductor abuts against the electrical contact, and the other end of the elastic conductor abuts against the head of the first comb tooth.

[0017] Under the action of elastic force, one end of the elastic conductor is tightly attached to the head of the first comb tooth, and the other end of the elastic conductor is tightly attached to the conductive contact of the first circuit board, thereby ensuring the conductive effect of the first comb tooth and the first circuit board. In addition, the elastic conductor is elastic, and the first comb tooth can move up and down. When combing hair, it can buffer the pressure applied by the comb and improve the comfort of the contact between the first comb tooth and the scalp.

[0018] Furthermore, the conductive contacts include positive conductive contacts and negative conductive contacts, the positive conductive contacts and the negative conductive contacts are arranged at intervals on the first circuit board, and the positive conductive contacts and the negative conductive contacts are arranged adjacent to each other, and the positive conductive contacts and the negative conductive contacts are respectively provided with the elastic conductor.

[0019] Since the positive conductive contact and the negative conductive contact are arranged adjacent to each other, the two adjacent first comb teeth are respectively the positive pole and the negative pole. The smaller the distance between the positive pole and the negative pole between the first comb teeth, the smaller the voltage step. A relatively small enable can produce an effect, and the body can also feel it. The output is more subtle and soft, and the comfort can be greatly improved.

[0020] Furthermore, the positive conductive contact and / or the negative conductive contact are connected to a resistor. If a short circuit occurs between two adjacent first comb teeth in a group, power is absorbed by the resistor, causing the short-circuited first comb teeth to stop working while the other first comb teeth remain unaffected and the first circuit board will not be burned, thereby greatly improving the safety of the hair care comb.

[0021] Furthermore, the second comb teeth include a ceramic shell, a conductive post, and an insulating sleeve. The lower end of the ceramic shell is provided with a protrusion, and the insulating sleeve is positioned over the conductive post. The insulating sleeve and the conductive post are simultaneously positioned within the ceramic shell. The comb tooth holder is provided with intermittent sockets, and the upper ends of the ceramic shells of the second comb teeth are positioned within corresponding sockets. The upper ends of the conductive posts pass through the sockets and are electrically connected to the second circuit board. The plasma generator can ionize the air above the scalp through the second comb teeth to form plasma. Plasma is a state of charged particles in a gas that releases energy. This energy can stimulate scalp cells and hair follicles, promoting hair growth and enhancing the effectiveness of hair growth treatment.

[0022] Furthermore, the protrusion is a hemispherical protrusion, and the lower end of the second comb tooth adopts a hemispherical protrusion, which can improve the comfort when combing hair and has a good spherical discharge effect.

[0023] Furthermore, the spacing between the first and second comb teeth is 3mm-5mm, the lower ends of the second comb teeth are higher than the lower ends of the first comb teeth, and the second and first comb teeth form a height difference of 1mm-5mm. Adjusting the spacing between the first and second comb teeth to between 3mm-5mm avoids the risk of high-voltage discharge in the plasma generator due to excessive proximity, improves safety, and meets the requirements of simultaneous operation of the EMS microcurrent generator and plasma generator. In addition, the spacing between the first and second comb teeth is between 3mm-5mm, which avoids sparse comb teeth and improves the combing effect of the hair care comb. Furthermore, the second comb teeth are 1-3mm lower than the first comb teeth, which is conducive to controlling the appropriate discharge gap between the second comb teeth and the scalp.

[0024] Furthermore, the comb tooth seat is divided into a first comb tooth installation area and a second comb tooth installation area, a first partition is arranged between the first comb tooth installation area and the second comb tooth installation area, the first circuit board is arranged in the first comb tooth installation area, and the second circuit board is arranged in the second comb tooth installation area, and the height of the first partition is higher than the height of the first circuit board and the second circuit board.

[0025] The comb tooth seat is a non-conductive comb tooth seat, and the first partition is a non-conductive partition. When the first circuit board and the second circuit board are installed, the height of the first partition is higher than the height of the first circuit board and the second circuit board and separates the first circuit board and the second circuit board, reducing interference and risks between circuits. In addition, the shortest distance required for current conduction between circuit boards is increased, that is, the creepage distance is increased, which can reduce electrical interference and risks between circuits. The first partition creates physical isolation between circuits and reduces the risk of high-voltage breakdown.

[0026] Furthermore, the first circuit board is provided with a first plug-in terminal, the second circuit board is provided with a second plug-in terminal, and the control circuit board is provided with a first plug-in socket and a second plug-in socket. The first plug-in terminal is inserted into the first plug-in socket, and the second plug-in terminal is inserted into the second plug-in socket to realize electrical connection between the first circuit board, the second circuit board and the control circuit board.

[0027] The first circuit board is electrically connected to the control circuit board by plugging, and the second circuit board is electrically connected to the control circuit board by plugging. The electrical connection by plugging reduces the cumbersome wiring of a large number of wiring harnesses and simplifies the installation process.

[0028] Furthermore, it also includes a vibration device and a battery, which are arranged in the shell, and the vibration device and the battery are electrically connected to the control circuit board respectively. The control circuit board is provided with a charging socket, and the charging socket is electrically connected to the control circuit board.

[0029] The vibration device generates vibration, which is transmitted to the scalp through the first comb teeth and the second comb teeth, helping to increase blood circulation in the scalp, stimulate hair follicles, promote hair growth, and help reduce dandruff and improve hair quality.

[0030] Furthermore, the plasma generator is provided with an LED lamp bead, the comb tooth seat is separated into a light-transmitting area, a second partition is provided between the light-transmitting area and the second comb tooth mounting area, and the LED lamp bead is placed in the light-transmitting area.

[0031] Users can select the corresponding mode and set the hair care comb to start or stop working. The light beads will emit different colors of light reminders to remind users whether the hair care comb has entered the working state. Other users will see the light change when the hair care comb starts or stops working, which will increase the attention of the hair care comb.

[0032] Furthermore, it also includes a lens, the light-transmitting area is separated by light-transmitting holes, and the lens is provided with light-transmitting convex columns at positions corresponding to the light-transmitting holes. The lens is placed in the light-transmitting area, and the light-transmitting convex columns pass through the light-transmitting holes.

[0033] Furthermore, the control device includes a power switch, a mode selection module and a touch switch, and the power switch, mode selection module and touch switch are respectively arranged on the shell, and the outer wall of the shell forms a touch area corresponding to the position of the touch switch.

[0034] The user presses the power switch to turn on the hair care comb, and then presses the mode selection module to start the corresponding working mode. At this time, the user touches the touch area with his hand to start the hair care comb. If the user leaves the touch area, the hair care comb stops working, which greatly improves the safety of the hair care comb.

[0035] The beneficial effects of the present invention are as follows:

[0036] According to the present invention, when a hair care comb is used for hair care, the EMS microcurrent generator generates EMS microcurrent through the first comb teeth. The EMS microcurrent transmits a weak current through contact with the scalp to stimulate the scalp and hair follicles, thereby promoting hair growth by increasing blood flow and stimulating scalp cells. The plasma generator excites ions in the air through the second comb teeth and releases energy, i.e., plasma. The plasma is used to stimulate scalp cells, improve blood circulation, promote hair growth, reduce dandruff, and improve hair quality. The first comb teeth and the second comb teeth are adjusted to a suitable spacing to avoid the risk of high-voltage discharge from the plasma generator due to excessive proximity, thereby improving safety and meeting the requirement for the EMS microcurrent generator and the plasma generator to operate simultaneously. The first comb teeth and the second comb teeth are appropriately spaced to avoid sparse comb teeth and improve the combing effect of the hair care comb. Furthermore, a height difference is formed between the lower end of the second comb teeth and the lower end of the first comb teeth, which is conducive to controlling a suitable discharge gap between the second comb teeth and the scalp.

[0037] In the present invention, since the positive conductive contact and the negative conductive contact are arranged adjacent to each other, the two adjacent first comb teeth are respectively the positive pole and the negative pole. The smaller the distance between the positive pole and the negative pole between the first comb teeth, the smaller the voltage step. A relatively small enable can produce an effect, and the body can also feel it. The output is more subtle and soft, and the comfort can be greatly improved.

[0038] According to the present invention, if a short circuit occurs between two adjacent first comb teeth in a group, the power is absorbed by the resistor, and the short-circuited first comb teeth stop working, while the other first comb teeth are not affected and the first circuit board will not be burned, thereby greatly improving the safety of the hair care comb.

[0039] The present invention adjusts the interval between the first comb teeth and the second comb teeth to be between 3 mm and 5 mm, thereby avoiding the risk of high-voltage discharge in the plasma generator due to too close a distance, improving safety, and meeting the requirement of simultaneous operation of the EMS microcurrent generator and the plasma generator. In addition, the first comb teeth and the second comb teeth are between 3 mm and 5 mm, thereby avoiding sparse comb teeth and improving the combing effect of the hair care comb. Furthermore, the height of the second comb teeth is 1-3 mm lower than that of the first comb teeth, which is conducive to controlling a suitable discharge gap between the second comb teeth and the scalp.

[0040] In the present invention, the lower end of the second comb tooth adopts a hemispherical protrusion, which can improve the comfort when combing hair and has a good spherical discharge effect.

[0041] In the present invention, the comb tooth seat is a non-conductive comb tooth seat, and the first partition is a non-conductive partition. When the first circuit board and the second circuit board are installed, the height of the first partition is higher than the height of the first circuit board and the second circuit board and separates the first circuit board and the second circuit board, reducing interference and risks between circuits. In addition, the shortest distance required for current conduction between circuit boards is increased, that is, the creepage distance is increased, which can reduce electrical interference and risks between circuits. The first partition creates physical isolation between circuits and reduces the risk of high-voltage breakdown. BRIEF DESCRIPTION OF THE DRAWINGS

[0082] Touch module 33: After the power of the hair care comb is turned on, the hair care comb can only work when the user's hand touches the touch area 12 and the first comb teeth 62 touch the skin. If the hand leaves the touch area 12 or the first comb teeth 62 leave the skin, the hair care comb stops working.

[0083] Working principle:

[0084] Startup mode 1:

[0085] The user presses the power switch 31 to turn on the hair care comb, and then presses the mode selection module 32 to start mode 1. At this time, the user touches the touch area 12 with his hand, and the hair care comb starts the EMS microcurrent generator 6, the vibration device 20 and the light.

[0086] The EMS microcurrent generator 6 generates EMS microcurrent through the first comb teeth 62. The EMS microcurrent transmits weak current through the scalp contact to stimulate the scalp and hair follicles, thereby promoting hair growth by increasing blood flow and stimulating scalp cells.

[0087] The vibration device 20 generates vibrations, which are transmitted to the scalp through the first comb teeth 62 and the second comb teeth 72, helping to increase blood circulation in the scalp, stimulate hair follicles, promote hair growth, and help reduce dandruff and improve hair quality.

[0088] The lamp beads generate light to remind the user that the hair care comb has entered the working state.

[0089] Since the chip of the control circuit board 4 sets the start and stop frequency of the EMS microcurrent generator 6, when the EMS microcurrent generator 6 is powered on and is in the working frequency band, the chip of the control circuit board 4 disconnects the power supply of the touch switch 33 to avoid conflicts caused by the EMS microcurrent generator 6 and the touch switch 33 working at the same time. When the EMS microcurrent generator 6 is in the stop frequency band, the chip of the control circuit board 4 connects the power supply of the touch switch 33. At this time, the touch switch 33 works normally. When the first comb teeth 62 of the touch switch 33 touch the skin, a closed circuit is generated, and the control circuit board 4 powers on the EMS microcurrent generator 6. This cycle repeats, thereby avoiding conflicts caused by the EMS microcurrent generator 6 and the touch switch 33 working at the same time, ensuring accurate detection of the touch switch 33.

[0090] Startup mode 2:

[0091] The user presses the power switch 31 to turn on the power of the hair care comb, and then presses the mode selection module 32 to start mode 1. At this time, the user touches the touch area 12 with his hand, and the hair care comb starts the plasma generator 7, the vibration device 20 and the light.

[0092] The plasma generator 7 excites ions in the air through the second comb teeth 72 and releases energy, namely plasma. The plasma is used to stimulate scalp cells, improve blood circulation, promote hair growth, reduce dandruff and improve hair quality.

[0093] The vibration device 20 generates vibrations, which are transmitted to the scalp through the first comb teeth 62 and the second comb teeth 72, helping to increase blood circulation in the scalp, stimulate hair follicles, promote hair growth, and help reduce dandruff and improve hair quality.

[0094] The light beads generate light to remind the user that the hair care comb has entered working state.

[0095] Since the chip of the control circuit board 4 sets the start and stop frequencies of the plasma generator 7, when the plasma generator 7 is powered on and is in the working frequency band, the chip of the control circuit board 4 disconnects the power supply of the touch switch 33 to avoid conflicts caused by the simultaneous operation of the plasma generator 7 and the touch switch 33. When the plasma generator 7 is in the stop frequency band, the chip of the control circuit board 4 connects the power supply of the touch switch 33. At this time, the touch switch 33 operates normally. When the touch area 12 of the touch switch 33 contacts the skin, a closed circuit is generated, and the control circuit board 4 energizes the plasma generator 7. This cycle repeats, thereby avoiding conflicts caused by the simultaneous operation of the plasma generator 7 and the touch switch 33 and ensuring accurate detection of the touch switch 33.
