Description

Technical Field

[0001] The present invention relates to the technical field of hair growth devices, in particular to a head-mounted hair growth device for promoting hair growth in patients with androgenic alopecia. Background Art

[0002] Head-worn hair growth devices are designed to help improve hair loss. They typically use phototherapy technology, emitting specific wavelengths of red or near-infrared light directly on the scalp and hair follicles. This light boosts cell metabolism, increases blood supply to hair follicles, reduces inflammation, and may reactivate dormant follicles, thereby stimulating hair growth.

[0003] Hair growth devices are widely used in the medical field, but due to the limitations of their structure and working principles, there are often some problems that cannot be ignored. The design of traditional head-mounted hair growth devices mainly focuses on using light of a specific wavelength to stimulate hair follicles, thereby improving hair loss. However, such devices usually lack the function of physically massaging the scalp. Massaging the scalp can relax tense muscles, promote blood circulation in the scalp, and further support hair growth, but traditional head-mounted hair growth devices often ignore this important link. In addition, traditional head-mounted hair growth devices cannot directly apply hair growth drugs to the scalp. This means that if users need to use drugs to assist hair growth, they must apply them manually, which increases the complexity of use. Summary of the Invention

[0004] In view of the problems in the existing technology that head-mounted hair growth devices cannot massage the scalp on the basis of light, and cannot assist in the application of drugs, a head-mounted hair growth device that promotes hair growth in patients with androgenic alopecia is proposed.

[0005] Its purpose is to enable the hair growth instrument to have the functions of massaging the scalp and applying medicine.

[0006] The technical solution of the present invention is a head-mounted hair growth device for promoting hair growth in patients with androgenic alopecia, comprising a helmet that emits infrared light, a strap disposed at the bottom of the helmet, a pressing mechanism disposed on the inner wall of the helmet, and a medicine supply mechanism disposed on the outer side of the helmet for squeezing out liquid medicine. The pressing mechanism includes a plurality of rectangular arrays of fixed plates arranged on the inner wall of the helmet, the fixed plates provide support points for the pressing mechanism, a support block arranged in the middle of the fixed plate, the support block fixes the mechanical components connected to the top, a shell arranged on the top of the support block, the shell protects the internal components, an electrode arranged on the inner wall of the shell, a wire arranged on the side of the electrode away from the shell, the electrode and the wire transmit voltage, a piezoelectric ceramic arranged on the side of the electrode away from the wire, the piezoelectric ceramic vibrates along the direction of the electric field after being connected to a voltage with a phase difference, the side of the piezoelectric ceramic away from the electrode is fixedly connected to the same wire, a pad arranged on the side of the piezoelectric ceramic away from the electrode, the pad will vibrate together with the piezoelectric ceramic, and an execution unit arranged on the side of the pad away from the piezoelectric ceramic.

[0007] Furthermore, the side of the pad away from the piezoelectric ceramic is a tooth-shaped structure, and the top of the shell is provided with a square hole that passes through to the bottom.

[0008] Furthermore, the execution unit includes a lifting rod arranged inside the shell, the top end of the lifting rod is slidably connected to the square hole of the shell, the side of the pad away from the piezoelectric ceramic is in contact with the lifting rod, pull rods are symmetrically arranged on both sides of the lifting rod, and a swing arm is symmetrically arranged at the bottom of the fixed plate, one end of the pull rod away from the lifting rod is rotatably connected to the middle part of the swing arm, a short shaft is arranged at the bottom of the swing arm, and a rubber plate is jointly arranged on the outside of the two short shafts, and the bottom end of the lifting rod is fixedly connected to the top of the rubber plate.

[0009] Furthermore, shaft holes are opened on both sides of the rubber plate, and the inner walls of the shaft holes are rotatably connected to the short shaft.

[0010] Furthermore, the lifting rod has a cross shape, and a stopper is provided on the top of the lifting rod.

[0011] Furthermore, the medicine supply mechanism includes a sleeve arranged on the outside of the helmet, a piston arranged inside the sleeve, a push rod arranged on the top of the piston, a catheter arranged on the side of the sleeve close to the helmet, a pipe network arranged on the end of the catheter away from the sleeve, a plurality of linear arrays of pressure blocks arranged at the bottom of the rubber plate, and a liquid outlet opened at the bottom of the pressure block, and the end of the pressure block away from the sleeve is fixedly connected to the pipe network.

[0012] Furthermore, the pipe network is composed of a plurality of manifolds, and a one-way valve is provided on the inner wall of the manifold.

[0013] Furthermore, a groove is provided on the outer side of the pressing block, and the liquid outlet is composed of a plurality of through holes penetrating into the interior of the pressing block.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a pressing mechanism, regular pressing actions can be performed on the skin of the head, touching the numerous nerve endings on the scalp. This massage can stimulate blood circulation in the scalp. Good blood circulation means that more oxygen and nutrients can be quickly delivered to the hair follicles, providing the necessary support for hair growth. After receiving adequate nutrition, the hair follicles can grow hair more healthily, thereby contributing to the growth and health of hair. In this way, the pressing mechanism not only improves the user's comfort, but also provides active assistance to the hair growth process by promoting blood circulation.

[0015] 2. By setting up a drug supply mechanism, hair growth drugs can be applied to the skin of the head. When the drugs come into contact with the scalp, they begin to exert their biological activity, act on the hair follicles, and create favorable conditions for hair growth. At the same time, the hair growth instrument is also equipped with a massage function. Massage can promote blood circulation of the scalp and enhance the absorption effect of drugs on the scalp. With the assistance of massage, the drugs can penetrate deeper into the scalp tissue and act more effectively on the hair follicle cells. This combination of drug application and massage provides double protection for the hair growth process.

[0016] 3. The provision of a sleeve and a piston facilitates drug management. The sleeve is used to store hair growth drugs, and the piston facilitates the control of drug release. Users can flexibly decide whether to use drugs according to their own needs. If drugs are needed to assist hair growth, just operate the piston to release an appropriate amount of drugs; if not needed temporarily, there is no need to use the drug part. This design makes the hair growth instrument no longer limited to a single function and increases its applicability. Whether it hopes to improve the scalp environment simply through physical methods or combine drugs for more comprehensive hair growth care, users can freely choose according to actual conditions, so that the hair growth instrument can better meet the needs of different groups of people.

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] Example 1, with reference to Figures 1-8 , which is the first embodiment of the present invention, provides a head-mounted hair growth device for promoting hair growth in patients with androgenic alopecia, comprising a helmet 1 for emitting infrared light, a strap 2 fixedly connected to the bottom of the helmet 1, a pressing mechanism 3 installed on the inner wall of the helmet 1, and a medicine supply mechanism 4 installed on the outside of the helmet 1 for squeezing out medicine; the pressing mechanism 3 includes a plurality of rectangular arrays of fixed plates 31 fixedly connected to the inner wall of the helmet 1, the fixed plate 31 providing a support point for the pressing mechanism 3, a support block 32 fixedly connected to the middle of the fixed plate 31, the support block 32 fixing the mechanical components connected to the top, and a shell 33 fixedly connected to the top of the support block 32. The shell 33 protects the internal components, and has an electrode 34 fixedly connected to the inner wall of the shell 33, a wire 35 fixedly connected to the side of the electrode 34 away from the shell 33, and the electrode 34 and the wire 35 transmit voltage. The piezoelectric ceramic 36 is fixedly connected to the side of the electrode 34 away from the wire 35. After the piezoelectric ceramic 36 is connected to a voltage with a phase difference, it vibrates along the direction of the electric field. The side of the piezoelectric ceramic 36 away from the electrode 34 is fixedly connected to the same wire 35. A pad 37 is fixedly connected to the side of the piezoelectric ceramic 36 away from the electrode 34. The pad 37 will vibrate along with the piezoelectric ceramic 36, and an actuator is assembled on the side of the pad 37 away from the piezoelectric ceramic 36.

[0021] Specifically, the helmet 1 can emit infrared light inside after being powered on. The connection between the fixing plate 31 and the helmet 1 forms a fixed point, so that the pressing mechanism 3 is fixed. The support block 32 fixes the shell 33. The shell 33 accommodates the piezoelectric ceramic 36 and fixes the electrode 34. The electrode 34 can fix the piezoelectric ceramic 36 and conduct current and voltage. When the piezoelectric ceramic 36 is connected to the voltage, it will vibrate and cause the pad 37 to vibrate. The pad 37 vibrates in an elliptical trajectory. By controlling the phase difference between the two phases, the pad 37 can vibrate along different trajectory directions.

[0022] Reference Figure 6 and Figure 7 The side of the pad 37 away from the piezoelectric ceramic 36 is a tooth-shaped structure, and the top of the shell 33 is opened with a square hole that passes through to the bottom.

[0023] Specifically, the pad 37 contacts the lifting rod 38 through one side of the tooth structure, and during the vibration process, pushes the lifting rod 38 to move in the direction of the vibration trajectory.

[0024] Reference Figures 1-8 The execution unit includes a lifting rod 38 that is slidably connected to the inside of the shell 33, the top of the lifting rod 38 is slidably connected to the square hole of the shell 33, the pad 37 is in contact with the lifting rod 38 on the side away from the piezoelectric ceramic 36, the pull rod 39 is symmetrically connected to both sides of the lifting rod 38, the swing arm 310 is symmetrically connected to the bottom of the fixed plate 31, the end of the pull rod 39 away from the lifting rod 38 is rotatably connected to the middle part of the swing arm 310, the short shaft 311 is fixedly connected to the bottom of the swing arm 310, and the rubber plate 312 is rotatably connected to the outside of the two short shafts 311, and the bottom end of the lifting rod 38 is fixedly connected to the top of the rubber plate 312.

[0025] Specifically, the lifting rod 38 can move under the drive of the pad 37. The freedom of the lifting rod 38 is constrained by the square hole on the top of the shell 33, so it can only move up and down. The pull rod 39 moves with the lifting rod 38 and transmits the force to the swing arm 310 during the movement. The top of the swing arm 310 is constrained by the fixed plate 31, so after receiving the force, it will rotate around the connection with the fixed plate 31. When the swing arm 310 rotates, it drives the short shaft 311 to move together. At the same time, the short shaft 311 moves. When the lifting rod 38 moves downward, it drives the side connected to the rubber plate 312 to move at the same time. The rubber plate 312 is deformed by the short shafts 311 on both sides. When the lifting rod 38 moves downward, the two rotary arms 310 are pushed to expand through the pull rod 39. The two rotary arms 310 move the two ends of the rubber plate 312 away from each other through the corresponding short shafts 311. When the lifting rod 38 moves downward, it will drive the middle part of the rubber plate 312 to deform downward. When the lifting rod 38 rises, it drives the middle part of the rubber plate 312 to rise. At the same time, through the pull rod 39, the two rotary arms 310 drive the two ends of the rubber plate 312 to move closer to each other.

[0026] Reference Figure 8 Axial holes are opened on both sides of the rubber plate 312, and the inner walls of the axis holes are rotatably connected to the short shaft 311.

[0027] Specifically, the rubber plate 312 is connected to the short shaft 311 through the shaft hole. Otherwise, the edge of the rubber plate 312 is deformed, making it unable to maintain the sheet-like structure.

[0028] Reference Figure 4 The lifting rod 38 has a cross shape, and a stopper is provided on the top of the lifting rod 38 .

[0029] Specifically, the lifting rod 38 is connected to different components through a cross-shaped structure, and the stopper cannot pass through the square hole of the shell 33 because the maximum downward stroke of the lifting rod 38 can be limited by the stopper.

[0030] Example 2, reference Figures 1-13 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the medicine supply mechanism 4 includes a sleeve 41 fixedly connected to the outside of the helmet 1, a piston 42 slidably connected to the inside of the sleeve 41, a push rod 43 fixedly connected to the top of the piston 42, a conduit 44 fixedly connected to the side of the sleeve 41 close to the helmet 1, a pipe network 45 fixedly connected to the end of the conduit 44 away from the sleeve 41, a plurality of linear arrays of pressure blocks 46 fixedly connected to the bottom of the rubber plate 312, and a liquid outlet 47 opened at the bottom of the pressure block 46, and the end of the pressure block 46 away from the sleeve 41 is fixedly connected to the pipe network 45.

[0031] Specifically, the interior of the sleeve 41 can accommodate a certain amount of liquid medicine. The push rod 43 squeezes the piston 42 downward to increase the pressure inside the sleeve 41, thereby pushing the liquid medicine into the catheter 44. The liquid medicine enters the pipe network 45 through the catheter 44. After the liquid medicine is diverted by the pipe network 45, it enters different pressing blocks 46 and finally overflows through the liquid outlet 47. The pressing block 46 contacts the scalp, so the liquid medicine will be applied to the scalp after overflowing.

[0032] Reference Figures 9-13 The pipe network 45 is composed of several manifolds, and a one-way valve is provided on the inner wall of the manifold.

[0033] Specifically, when the pressure inside the sleeve 41 increases to a certain level, the liquid medicine will push open the one-way valve and enter different pressing blocks 46 .

[0034] Reference Figure 13 A groove is provided on the outer side of the pressing block 46 , and the liquid outlet 47 is composed of a plurality of through holes penetrating into the interior of the pressing block 46 .

[0035] Specifically, the liquid medicine overflows into the groove of the pressing block 46 through the liquid outlet 47 and flows along the groove, thereby increasing the area for applying the medicine. The rest of the structure is the same as that of the first embodiment.

[0036] In summary, the working principle of the present invention is as follows: the helmet 1 is worn on the head, and the strap 2 is tied at the lower jaw. When the hair growth device is powered on, infrared light is generated to irradiate the scalp. When the scalp needs to be massaged, the wire 35 is connected to the power supply. The current passes through the electrode 34 and the piezoelectric ceramic 36 in sequence. The piezoelectric ceramic 36 vibrates after the voltage is connected, and at the same time drives the pad 37 to vibrate together. The pad 37 vibrates and drives the lifting rod 38 to move. When the lifting rod 38 moves down, the two pull rods 39 push the corresponding rotary arm. 310. The two rotating arms 310 expand under force. As the rotating arms 310 expand, the ends of the rubber plate 312 are driven away from each other via the short shaft 311. As the lifting rod 38 moves downward, it presses down the middle of the rubber plate 312 via its bottom end. As the ends of the rubber plate 312 move away from each other, the rubber plate 312 deforms toward a nearly flat state. At this time, the ends of the rubber plate 312 gradually lose contact with the scalp. As the middle of the rubber plate 312 is pressed by the lifting rod 38, the contact force between the middle of the rubber plate 312 and the scalp gradually increases. When the lifting rod 38 moves upward, it will pull the middle part of the rubber plate 312 upward, so that the middle part of the rubber plate 312 gradually releases contact with the scalp, and the lifting rod 38 will pull the rotary arm 310 to contract through the pull rod 39, thereby driving the two ends of the rubber plate 312 to contract, increasing the contact force between the two ends of the rubber plate 312 and the scalp. The lifting rod 38 can massage the scalp through the rubber plate 312 through up and down reciprocating motion. When medicine needs to be applied to the scalp, the medicine is pumped to the pressure block 46 through the conduit 44 and the pipe network 45 by squeezing the piston 42. The medicine enters the groove of the pressure block 46 through the liquid outlet 47 and flows along the groove to increase the distribution of the medicine. By cooperating with the massaging action of the rubber plate 312, the medicine is applied to the patient's head.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
