Description

Technical Field

[0001] This utility model relates to the field of physiotherapy technology, specifically to a portable acupoint massager. Background Technology

[0002] Mosquito bites are common, especially in summer. When bitten, they often cause itching, discomfort, and unbearable itch. Scratching is unhygienic and tiring; if the skin breaks, it can fester, become infected, and cause damage to health. To address this, people have developed various anti-itch devices, such as anti-itch rakes, and anti-itch medications, such as floral water and medicated oils. However, these cannot completely relieve the itch.

[0003] A search revealed a pen-shaped mosquito bite itch reliever, disclosed in patent publication number CN1475284A. While this pen-shaped device is small and portable, making it ideal for home and travel use, and causing no environmental pollution or skin infection, its practical application presents challenges. Users often have obstructed views, making it difficult to accurately locate the itch reliever and thus affecting its effectiveness. Furthermore, accidental activation is common. Users may accidentally activate the itch reliever due to hand movements, especially in unfamiliar environments. Such accidental activation could lead to unnecessary electrical stimulation and discomfort. Utility Model Content

[0021] The symmetrically distributed grip bars provide users with a uniform holding force, allowing the massager to remain balanced and stable during operation. This helps ensure that the massager can accurately target the desired area, avoiding errors caused by hand wobbling.

[0022] Furthermore, a limiting frame is provided inside the housing, and the piezoelectric ceramic voltage generator is installed inside the housing by limiting the position of the limiting frame.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The limiting bracket provides a stable mounting base for the piezoelectric ceramic voltage generator, preventing displacement or shaking due to vibration or external forces during operation. The limiting bracket effectively protects the piezoelectric ceramic voltage generator from damage caused by direct pressure or impact from the housing or other components. This helps extend the service life of the piezoelectric ceramic voltage generator and reduces maintenance and replacement costs. The design of the limiting bracket makes the installation and disassembly of the piezoelectric ceramic voltage generator simpler and more convenient. During assembly, the limiting bracket serves as a reference point for positioning and fixing, ensuring that the piezoelectric ceramic voltage generator is accurately installed inside the housing. During maintenance, the limiting bracket also facilitates the disassembly and inspection of the piezoelectric ceramic voltage generator.

[0027] By adjusting the threaded design on the cover, users can easily adjust the height of the cover protruding from the housing, thereby adjusting the distance between the button and the pressing block. When the cover is in its highest position, the button will not contact the pressing block, effectively preventing accidental activation.

[0028] The piezoelectric ceramic voltage generator emits a current of only 0.7mA, which is within a safe current range and will not cause harm to the human body. Meanwhile, the rounded end of the metal head of the massage device reduces discomfort during use and makes it easy to visually observe the area being treated. This massager masks the original itching sensation by generating a slight pain sensation, thus eliminating the root cause of the itching. This electrical stimulation method not only has a significant anti-itch effect but also promotes local blood circulation and relieves muscle tension to some extent. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0038] Example 1

[0039] A portable acupoint massager includes a housing 2, within which a piezoelectric ceramic voltage generator 6 is installed. A limiting bracket 201 is provided within the housing 2, which secures the piezoelectric ceramic voltage generator 6 within the housing 2. The limiting bracket 201 provides a stable mounting base for the piezoelectric ceramic voltage generator 6, preventing displacement or shaking due to vibration or external forces during operation. The limiting bracket 201 effectively protects the piezoelectric ceramic voltage generator 6, preventing damage caused by direct pressure or impact from the housing 2 or other components. This helps extend the service life of the piezoelectric ceramic voltage generator 6 and reduces maintenance and replacement costs. The design of the limiting bracket 201 simplifies and facilitates the installation and removal of the piezoelectric ceramic voltage generator 6. During assembly, the limiting bracket 201 serves as a reference point for positioning and fixing, ensuring that the piezoelectric ceramic voltage generator 6 is accurately installed within the housing 2. During maintenance, the piezoelectric ceramic voltage generator 6 can be easily disassembled and inspected using the limit bracket 201. The outer casing 2 has gripping rods 4 on both sides. When pressing button 1, the user holds the outer casing 2 by gripping the gripping rods 4. The gripping rods 4 provide additional support points, allowing the outer casing 2 to be held more stably in the hand when pressing button 1, preventing it from slipping or shaking. This helps ensure that the massager can accurately target acupoints or areas, improving accuracy and effectiveness. The gripping rods 4 are symmetrically distributed on both sides of the outer casing 2, providing a uniform gripping force and ensuring the massager remains balanced and stable during operation. This helps ensure that the massager can accurately target the area, avoiding errors caused by hand movement. An adjustment cover 5 is installed at the top of the outer casing 2, and a button 1 is movably installed inside the adjustment cover 5. The outer surface of the button 1 has a slider 101, and the inner surface of the adjustment cover 5 has a groove 501. The button 1 is positioned within the adjustment cover 5 by the slider 101 and the groove 501. The cooperative design of the slider 101 and the groove 501 ensures the stable installation of the button 1 within the adjustment cover 5. This structure restricts the movement of the button 1 in both the horizontal and vertical directions, preventing the button 1 from shaking or falling off during use.A stable installation structure helps ensure that the massager can accurately respond to user commands during operation, improving the reliability and durability of the device. The outer side of the adjustment cover 5 is provided with a pipe thread 502. The adjustment cover 5 is movably installed on the top of the outer shell 2 through the pipe thread 502. The height of the adjustment cover 5 protruding from the outer shell 2 is adjusted by the pipe thread 502, thereby adjusting the distance between the button 1 and the pressing block 601. When the adjustment cover 5 is in the highest position, pressing the button 1 will not contact the pressing block 601, thus preventing accidental activation. When the adjustment cover 5 is in the lowest position, pressing the button 1 will press the pressing block 601 downwards, triggering the piezoelectric ceramic voltage generator 6. The user can adjust the height of the adjustment cover 5 protruding from the outer shell 2 by simply rotating it, thereby achieving precise control of the displacement distance of the button 1. This adjustment method is intuitive and easy to operate, requiring no additional tools or complicated steps. The bottom of the housing 2 is provided with a massage head 3, which has a first metal head 301 and a second metal head 302. The ends of the second metal head 302 and the first metal head 301 are arc-shaped, and the first metal head 301 and the second metal head 302 are electrically isolated from each other by an insulating pad.

[0040] Example 2

[0041] To achieve the purpose of relieving itching, for example, such as Figures 1 to 3 As shown, the present invention further includes: a pressing block 601 is provided at the top of the piezoelectric ceramic voltage generator 6, the piezoelectric ceramic voltage generator 6 is provided with a first wire 602 and a second wire 603, and the piezoelectric ceramic voltage generator 6 is electrically connected to the second metal head 302 and the first metal head 301 respectively through the first wire 602 and the second wire 603. By generating voltage stimulation on the skin surface through the first metal head 301 and the second metal head 302, the piezoelectric ceramic voltage generator 6 emits a safe current of 0.7mA, causing a slight pain sensation in the affected area of ​​the human body. This slight pain sensation can fully mask the original uncomfortable itching sensation, thereby fundamentally eliminating the cause of itching and achieving the purpose of relieving itching.

[0042] Working principle:

[0043] When the user presses button 1, button 1 moves steadily downward within the adjustment cover 5 via the internal slider 101 and groove 501 structure. When button 1 is pressed to a certain displacement distance (this distance is determined by the height of the adjustment cover 5), it contacts the pressing block 601 at the top of the piezoelectric ceramic voltage generator 6. Upon contact, the piezoelectric ceramic voltage generator 6 is stimulated by pressure, thereby generating electrical energy. This electrical energy is transmitted through the internal first wire 602 and second wire 603 to the first metal head 301 and second metal head 302 of the massage head 3, respectively.

[0044] The electrical energy generated by the piezoelectric ceramic voltage generator 6 produces a voltage stimulation between the two metal heads of the massage head 3. Because the two metal heads are electrically isolated by an insulating pad, they can act as positive and negative electrodes respectively, thus creating an electric field on the skin surface. When this electric field acts on human skin, it generates a weak current stimulation. This current intensity is controlled within a safe range (e.g., 0.7mA) and will not cause harm to the human body.

[0045] When electrical stimulation is applied to human skin, it causes a mild pain sensation. This pain masks the original itching sensation, thus relieving the user's itching symptoms. At the same time, electrical stimulation can also promote local blood circulation, relieve muscle tension, and further improve skin discomfort.

[0046] Users can adjust the height of the adjustment cover 5 to change the distance between the button 1 and the pressing block 601, preventing accidental activation when not in use.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
