Description

Technical Field

[0001] This application belongs to the field of medical devices, specifically relating to an electric plum blossom needle. Background Technology

[0002] Plum blossom needle therapy, as one of the traditional Chinese medicine therapies, is widely used in dermatology, neurorehabilitation, and other fields, and has unique advantages, especially in the treatment of hair growth and development. Traditional plum blossom needle therapy relies on the operator's technique and experience, and suffers from problems such as uneven tapping force, uncontrollable frequency, and susceptibility to cross-infection. In recent years, with the development of electronic technology, electric plum blossom needles have gradually become a research hotspot, but they still have shortcomings. For example, existing electric plum blossom needles mostly use simple mechanical vibration to achieve tapping, resulting in unstable tapping force and frequency, and difficulty in controlling precision. This may lead to excessively strong stimulation (damaging the skin) or insufficient stimulation (insufficient therapeutic effect), especially with poor adaptability to sensitive areas (such as the face and joints). Summary of the Invention

[0020] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0021] like Figure 1-3 As shown, this application provides an electric plum blossom needle, comprising: a handheld part 10, an electric drive rotation mechanism 20, a cam linear reciprocating mechanism 30, and a plum blossom needle body structure 40; wherein, the electric drive rotation mechanism 20 is disposed within the handheld part 10; the cam linear reciprocating mechanism 30 is connected to the electric drive rotation mechanism 20 in a transmission manner; the plum blossom needle body structure 40 is slidably disposed within the handheld part 10, and the electric drive rotation mechanism 20 drives the cam linear reciprocating mechanism 30 to drive the plum blossom needle body structure 40 to reciprocate linearly.

[0022] Compared with existing technologies, the electric plum blossom needle provided in this application, after the electric drive rotation mechanism 20 is started, transmits the rotational power to the cam linear reciprocating mechanism 30. The cam linear reciprocating mechanism 30 converts the rotational motion into linear reciprocating motion, driving the plum blossom needle body structure 40 to slide within the handheld part 10, thereby realizing the regular tapping action of the plum blossom needle head 430. Through the precise cooperation between the electric drive rotation mechanism 20 and the cam linear reciprocating mechanism 30, the tapping frequency and force are precisely controlled by the motor speed and cam profile, solving the problems of uneven force and unstable frequency in traditional manual operation, and is especially suitable for the treatment of sensitive areas.

[0023] It should be noted that the handheld part 10 is designed with an eggshell structure, which conforms to the principles of ergonomics. It can also be equipped with a smart control interface and wireless charging function in the future to improve the user experience.

[0024] In one possible implementation, the cam linear reciprocating mechanism 30 includes a rotating shaft 310 rotatably connected within the handheld part 10, a cylindrical cam 320 concentrically connected to the rotating shaft 310, and a roller follower 330 engaging with the groove 321 or ridge of the cylindrical cam 320. The roller follower 330 slides within the handheld part 10 and is drively connected to the swivel needle body structure 40. Specifically, the rotating shaft 310 is connected to a drive motor 210, which drives the cylindrical cam 320 to rotate. The rollers 332 of the roller follower 330 engage with the groove 321 of the cylindrical cam 320 or move along the ridge, converting the cam rotation into linear reciprocating motion of the roller follower 330, thereby driving the swivel needle body structure 40. The engagement between the cylindrical cam 320 and the rollers 332 achieves high-precision motion conversion, resulting in a compact structure and high transmission efficiency, ensuring the stability and controllability of the striking action.

[0025] In one possible implementation, the roller follower 330 includes a follower body 331 and a roller 332 rotatably connected to the follower body 331. The roller 332 moves along the groove 321 or ridge of the cylindrical cam 320 to drive the follower body 331. The follower body 331 slides within the handle portion 10 and is connected to the pin body structure 40. Specifically, the roller 332 rolls along the contour of the cylindrical cam 320, causing the follower body 331 to slide along the linear guide groove 110 within the handle portion 10, thereby driving the pin body structure 40 to move. The rolling friction of the roller 332 reduces motion resistance and extends component life; the guide groove design further restricts the motion trajectory and prevents deviation.

[0026] In one possible implementation, a guide slider 333 is provided on the driven body 331, and a linear guide groove 110 is provided inside the handheld part 10. The guide slider 333 slides in conjunction with the linear guide groove 110. Specifically, the guide slider 333 is embedded in the linear guide groove 110, restricting the driven body 331 to move linearly only in a preset direction. This enhances movement stability, prevents percussion deviation caused by lateral offset, and improves treatment accuracy.

[0027] In one possible implementation, the electrically driven rotation mechanism 20 includes a drive motor 210 and a transmission component 220 connected to the output shaft of the drive motor 210. The transmission component 220 is driven by a cam linear reciprocating mechanism 30, and includes a speed-changing gear set. Specifically, the drive motor 210 adjusts its output speed and torque through the speed-changing gear set to adapt to different tapping frequency requirements. The variable speed design expands the applicability of the device, allowing users to adjust the tapping intensity according to the treatment area (such as the scalp or face).

[0028] In one possible implementation, the drive motor 210 is a servo motor, a stepper motor, or a geared motor. Understandably, a servo motor or stepper motor precisely controls its speed via pulse signals; a geared motor reduces speed and increases torque via gear sets. This diverse range of motor options meets the needs of different scenarios; the high-precision control of servo / stepper motors further optimizes the striking parameters.

[0029] In one possible implementation, a battery pack 50 is housed within the handheld unit 10. An electrode patch 60 is connected to the negative terminal of the battery pack 50, and the plum blossom needle body structure 40 is a conductor connected to the positive terminal of the battery pack 50. During treatment, the electrode patch 60 adheres to the skin, and the plum blossom needle tip 430 releases a microcurrent through the conductive needle body while tapping, promoting the absorption of medication or stimulating acupoints. The synergistic effect of electrotherapy and mechanical tapping enhances the therapeutic effect; the integrated design reduces operational steps and lowers the risk of cross-infection.

[0030] In one possible implementation, the drive motor 210 is electrically connected to the battery pack 50, offering greater operational flexibility and convenience. In another embodiment, the drive motor 210 can also be connected to an external power source.

[0031] In one possible implementation, the plum blossom needle body structure 40 includes a guide rod 410 fixedly connected within the handheld part 10, a movable rod 420 movably sleeved with the guide rod 410, and a plum blossom needle head 430 connected to the movable rod 420. A cam linear reciprocating mechanism 30 is driven by the movable rod 420. Specifically, the movable rod 420 slides back and forth along the guide rod 410 under the drive of the cam mechanism, driving the plum blossom needle head 430 to perform tapping. The guide rod 410 provides rigid support to ensure that the tapping direction is perpendicular to the skin surface, avoiding damage caused by oblique impact.

[0032] It should be noted that the front end of the handheld part 10 has a linear guide groove 2 120, which allows the plum blossom needle 430 to reciprocate in the linear guide groove 2 120.

[0033] In one possible implementation, the movable rod 420 includes two rods, a first rod 421 and a second rod 422, screwed together for adjusting the length of the movable rod 420. The tufted needle 430 is screwed to the movable rod 420. Rotating to adjust the screwed length of the first rod 421 and the second rod 422 changes the total length of the movable rod 420, thereby adjusting the percussion depth. Personalized adjustment adapts to different treatment needs (such as superficial stimulation or deep penetration), improving the versatility of the device.

[0034] In one possible implementation, the plum blossom needle 430 includes a hollow box 431 and multiple hollow needles 432 disposed on one side of the hollow box 431. One end of each hollow needle 432 is equipped with a ball bearing 433. A piston 434 or a flexible partition is disposed inside the hollow box 431. The side of the piston 434 or flexible partition closest to the hollow needle 432 is used to load liquid medication, and the other side is used to fill with gas. The hollow needle 432 communicates with the cavity containing the liquid medication. The ball bearing 433 is built into the hollow needle 432. During tapping, the ball bearing 433 is pressed to open the needle channel, and the piston 434 pushes the liquid medication through the needle to inject it into the skin. The gas-filled side controls the amount of liquid medication delivered through air pressure. This allows tapping and drug delivery to be performed simultaneously, improving treatment efficiency. The ball bearing 433 design prevents liquid medication spillage, ensuring accurate dosage.

[0035] The operating procedure for the electric plum blossom needle provided in this application is as follows: Install battery pack 50 and turn on the machine. Adjust the tapping frequency using the speed gear set. Apply electrode patch 60 to the treatment area and select a suitable plum blossom needle 430 (such as the type with medicine solution). Rotate the movable lever 420 to adjust the tapping depth, and start the equipment for automatic tapping. After treatment, turn off the power and disassemble the plum blossom needle, sterilize it with 430 for later use.

[0036] The electric plum blossom needle of this application achieves high-precision control of the tapping motion through the synergistic effect of electric drive and cam mechanism, solving the problems of uneven force and unstable frequency in traditional therapies. Combined with electrotherapy and drug delivery functions, it significantly improves the treatment effect. At the same time, the modular design (such as the adjustable movable rod 420 and replaceable needles) enhances the adaptability and safety of the device, making it suitable for clinical and home settings.
