Description

Technical Field

[0001] This utility model relates to the field of massager technology, specifically a cold compress vibration anti-itch massager. Background Technology

[0002] Currently, massagers are widely used in modern society as a common physiotherapy and health care device to relieve muscle fatigue, promote blood circulation, and improve physical discomfort. However, existing massagers still have many shortcomings in functional design and technical implementation, making it difficult to meet users' comprehensive needs for multifunctionality, comfort, and therapeutic effects. For example, traditional massagers usually only have a single vibration or pressing function, which cannot effectively address complex physical conditions such as itchy skin, local inflammation, or symptoms requiring cold compresses. In addition, existing devices are poorly designed for drug delivery, making it difficult to achieve the synergistic effect of medication and physical massage, thus limiting their application value in the field of medical assistance.

[0003] Meanwhile, the structural design of existing massagers is often relatively fixed, lacking flexibility and adaptability. This prevents the devices from effectively conforming to the curves of the human body when used on different parts of the body, affecting the massage effect. On the other hand, although some massagers are equipped with a cooling function, the combination of cooling and vibration functions is not tight enough to achieve simultaneous effects, and the coverage of the cooling area is limited, failing to meet the treatment needs of large areas or deep tissues. In addition, during the drug delivery process, existing devices usually lack a precise drug distribution control mechanism, which may lead to wasted drug efficacy or excessively high local concentrations, thereby affecting the safety and effectiveness of the treatment.

[0004] In summary, existing massagers suffer from shortcomings in functional integration, structural design, and drug delivery, which limit their practical application. Therefore, there is an urgent need for a multifunctional massager that organically combines cooling, vibration, and drug delivery functions, while also providing highly effective antipruritic effects, to address the aforementioned technical issues and enhance the user experience. Utility Model Content

[0005] This invention addresses the problem in existing technologies where it is difficult to integrate cold compress, vibration, antipruritic, and drug penetration functions, proposing a compact and fully functional cold compress vibration antipruritic solution.

[0006] Massager. Therefore, the present invention adopts the following technical solution: This utility model provides a cold compress vibration anti-itch massager, including a housing, a cover, a bidirectional motor, a worm gear transmission system, a gear transmission system, a vibration system, a massage hand linkage mechanism, and a drug delivery system. The cover is fixed to the top of the housing with screws, protecting the internal components and forming the overall appearance structure. A bidirectional motor is fixedly installed inside the housing, with its two output ends connected to worm gears via couplings. The worm gears mesh with worm wheels, forming a worm gear transmission system.

[0007] Furthermore, a drive shaft and a driven shaft are rotatably mounted inside the housing. A drive gear is fixedly sleeved on the outside of the drive shaft, and a driven gear is fixedly sleeved on the outside of the driven shaft. The two are meshed together to form a gear transmission system. The worm gear is fixedly sleeved on the outside of the drive shaft and drives the drive shaft to rotate through the worm gear transmission, thereby transmitting power to the gear transmission system. This design utilizes the high reduction ratio characteristics of the worm gear transmission to achieve smooth power transmission, while further distributing power through the gear transmission system to provide stable driving force for subsequent functional modules.

[0008] Specifically, the vibration system includes a symmetrically arranged support, a vibration frame, a spring, a vibration ring, and protrusions. The support is fixed inside the housing with countersunk screws, and the vibration frame is fixed to the support with nuts and bolts. A vibration ring is fixedly sleeved on the outside of the drive shaft, and the outer circumference of the vibration ring has protrusions distributed in a ring, which are in close contact with the inner wall of the vibration frame. When the drive shaft rotates, the vibration ring rotates synchronously with it, and the interaction between the protrusions and the inner wall of the vibration frame produces a vibration effect. In addition, a spring is fixed to one side of the support, and one end of the spring is fixedly connected to the vibration frame by a clip, providing elastic support. This design, through the mechanical friction between the protrusions and the vibration frame combined with the elastic action of the spring, makes the vibration effect more stable and controllable.

[0009] Furthermore, the massage tentacle linkage mechanism includes a support plate, a second universal ball joint, a connecting rod, a first universal ball joint, an extension column, and a massage tentacle. The support plate is fixed to one end of the housing with screws, and second universal balls are rotatably mounted on both sides of the housing and the support plate. One end of the connecting rod is connected to one side of the second universal ball joint, and the other end of the connecting rod is connected to the first universal ball joint. An extension column is rotatably connected to one side of the first universal ball joint, and a massage tentacle is connected to one end of the extension column. Connecting plates are fixedly sleeved on both ends of the driven shaft, and a cam is fixed to one side of each connecting plate. A circular hole is opened on the massage tentacle, and the highest point of the cam is in contact with the inner wall of the circular hole. With the driven shaft... The rotation of the cam drives the massage tentacles to move along the trajectory of the circular holes, thus achieving multi-directional massage movements. This design achieves flexible movement of the massage tentacles through a combination of omnidirectional balls and connecting rods, and uses a cam mechanism to precisely control the movement trajectory of the massage tentacles, enhancing the massage experience.

[0010] The drug delivery system includes a telescopic hood, a drug-permeable plate, a cooling compress, a drug inlet box, a drug guide block, and a drug inlet channel. Four symmetrically arranged telescopic hoods are slidably installed inside the housing. Each hood is a cavity structure with openings at both the top and bottom. A drug-permeable plate is fixedly connected to the bottom of all four hoods. The drug-permeable plate has several equally spaced, arrayed drug-permeable holes for drug penetration. A cooling compress is adhesively attached to the top of the drug-permeable plate. The cooling compress provides a cooling effect through its low-temperature properties, simultaneously relieving skin itching and discomfort in conjunction with the drug penetration function. A groove is provided on one side of the housing, and a drug inlet box is slidably connected inside the groove. An integrally formed drug guide block is provided on the bottom wall of the drug inlet box. The top of the drug guide block has two inclined surfaces to guide the drug into the telescopic hood. A drug inlet channel is provided inside the housing. The inlet of the drug inlet channel is connected to the groove, and the outlet is connected to the top openings of the four telescopic hoods, ensuring that the drug is evenly distributed and penetrates the drug-permeable plate. This design optimizes the drug flow path by using the inclined surface of the drug delivery block and achieves precise drug delivery through the synergistic effect of the drug inlet channel and the telescopic hood.

[0011] Furthermore, the cooling function is achieved by combining a cooling compress cloth with a transdermal patch. The cooling compress lowers the local skin temperature through a low-temperature environment, relieving inflammation and itching, while the transdermal patch's permeable pores allow drug molecules to pass through and act on the skin surface, enhancing the therapeutic effect. This design, through the dual effects of cooling and drug penetration, meets the user's need for rapid itch relief and soothing.

[0012] The technical effects of this utility model are as follows: Through the above structural design, multi-functional integration is achieved, including cold compress, vibration, antipruritic, and drug penetration functions; the use of a bidirectional motor, worm gear, and gear transmission system ensures smooth and reliable power transmission; the design of the medicine box, drug guide block, and drug penetration plate achieves uniform distribution and precise penetration of the drug; the linkage mechanism composed of universal ball, connecting rod, and cam enables the massage hands to move in multiple directions, enhancing the massage experience; the synergistic effect of spring, vibration ring, and protrusion provides a stable vibration effect, further enhancing the antipruritic and soothing effects.

[0013] In summary, this utility model provides a compact and fully functional cold compress vibration device. This dynamic anti-itch massager is suitable for skin care and massage needs in various scenarios.

Detailed Implementation

[0018] This utility model provides a cold compress vibration anti-itch massager, which has a compact structure and comprehensive functions, and can meet users' multiple needs for skin care and massage. The following is in conjunction with the attached... Figure 1 To be continued Figure 7 The specific embodiments of this utility model are described in detail below, along with the specific components indicated by the reference numerals in the accompanying drawings.

[0019] The overall structure of the cold compress vibration anti-itch massager is as follows: Figure 1As shown, the device includes a housing 1, a cover 2, a bidirectional motor 17, a worm gear transmission system, a gear transmission system, a vibration system, a massage tentacle linkage mechanism, and a drug delivery system. The housing 1 serves as the main frame of the entire device, supporting and protecting the internal components. The cover 2 is fixed to the top of the housing 1 with screws, forming a closed, integrated structure together. This design not only improves the aesthetics of the device but also effectively prevents external dust or foreign objects from entering the housing 1 and interfering with its normal operation.

[0020] The outer circumferential surface of the rotating ring is fixedly provided with protrusions 24 distributed in a ring, and the protrusions 24 are in close contact with the inner wall of the vibration frame 27.

[0021] A bidirectional motor 17 is fixedly installed inside the housing 1. This motor has two output ends, each connected to a worm gear 20 via a coupling. The worm gear 20 meshes with a worm wheel 18, forming a worm gear transmission system. The high reduction ratio of this system ensures smooth and reliable power transmission. Furthermore, the worm wheel 18 is fixedly sleeved on the outside of the drive shaft 23. When the bidirectional motor 17 starts, the worm gear 20 drives the worm wheel 18 to rotate, thereby transmitting power to the drive shaft 23. The drive shaft 23 and the driven shaft 26 are rotatably mounted inside the housing 1. A drive gear 19 is fixedly sleeved on the outside of the drive shaft 23, and a driven gear 25 is fixedly sleeved on the outside of the driven shaft 26. The drive gear 19 and the driven gear 25 mesh, forming a gear transmission system. The gear transmission system further distributes the power transmitted by the worm gear transmission system, providing stable driving force for subsequent functional modules.

[0022] The design of the vibration system is one of the key features of this invention. For example... Figure 5 and Figure 7 As shown, symmetrically arranged brackets 22 are fixed inside the housing 1 by countersunk screws, and a vibrating frame 27 is fixed to the brackets 22 by nuts and bolts. A vibrating ring is fixedly sleeved on the outside of the drive shaft 23, and the outer circumference of the vibrating ring has annularly distributed protrusions 24, which are in close contact with the inner wall of the vibrating frame 27. When the drive shaft 23 rotates, the vibrating ring rotates synchronously with it, and the mechanical friction between the protrusions 24 and the inner wall of the vibrating frame 27 generates a vibration effect. In addition, a spring 21 is fixed to one side of the bracket 22, and one end of the spring 21 is fixedly connected to the vibrating frame 27 by a buckle, providing elastic support. This design utilizes the interaction between the protrusions 24 and the vibrating frame 27, combined with the elastic characteristics of the spring 21, to make the vibration effect more stable and controllable. The introduction of the vibration system significantly improves the user experience of the massager, especially suitable for those who need to relieve muscle tension and Scenarios that promote blood circulation.

[0023] The design of the massage tentacle linkage mechanism further enhances the functionality of this utility model. For example... Figure 4 and Figure 6 As shown, a support plate 8 is fixed to one end of the housing 1 with screws. Second universal ball joints 7 are rotatably mounted on both sides of the housing 1 and the support plate 8. One side of the second universal ball joint 7 is connected to one end of a connecting rod 6, and the other end of the connecting rod 6 is connected to a first universal ball joint 5. An extension column 4 is rotatably connected to one side of the first universal ball joint 5, and one end of the extension column 4 is connected to a massage tentacle 3. Connecting plates 11 are fixedly fitted to both ends of the driven shaft 26, and a cam 9 is fixed to one side of the connecting plate 11. A circular hole is formed on the massage tentacle 3, and the highest point of the cam 9 is in contact with the inner wall of the circular hole. As the driven shaft 26 rotates, the cam 9 pushes the massage tentacle 3 to move along the trajectory of the circular hole, thereby achieving multi-directional massage movements. This design, through the combination of universal ball joints and connecting rods, gives the massage tentacle 3 flexible movement capabilities, while using a cam mechanism to precisely control the movement trajectory of the massage tentacle 3. This linkage mechanism is particularly suitable for massaging complex areas such as the back and neck, significantly improving user comfort.

[0024] The design of the drug delivery system is another major highlight of this invention. For example... Figure 3 and Figure 5 As shown, four symmetrically arranged telescopic covers 12 are slidably installed inside the housing 1. Each telescopic cover 12 is a cavity structure with openings at both the top and bottom. A drug-permeable plate 14 is fixedly connected to the bottom of all four telescopic covers 12. The drug-permeable plate 14 has several drug-permeable holes 15 arranged in an array at equal intervals for drug penetration. A cooling compress 13 is adhesively bonded to the top of the drug-permeable plate 14. The cooling compress 13 provides a cooling function through its low-temperature properties, while simultaneously relieving skin itching and discomfort in conjunction with the drug penetration function. A groove is provided on one side of the housing 1, and a drug inlet box 10 is slidably connected inside the groove. An integrally formed drug guide block 16 is provided on the bottom wall of the drug inlet box 10. The top of the drug guide block 16 has two inclined surfaces for guiding the drug into the telescopic covers 12. A drug inlet channel is provided inside the housing 1. The inlet of the drug inlet channel is connected to the groove, and the outlet is connected to the top openings of the four telescopic covers 12, ensuring that the drug can be evenly distributed and penetrate into the drug-permeable plate 14. This design optimizes the drug flow path through the inclined surface of the drug delivery block 16, and achieves precise drug delivery through the synergistic effect of the drug inlet channel and the telescopic cover 12. This drug delivery system is particularly suitable for treating skin inflammation, allergic reactions, and other conditions, and can significantly improve treatment efficacy.

[0025] The cold compress function is achieved jointly by the cold compress cloth 13 and the drug-permeable plate 14. The cold compress cloth 13 uses low... The warm environment lowers the local skin temperature, relieving inflammation and itching. The permeation holes 15 on the transdermal patch 14 allow drug molecules to pass through and act on the skin surface, enhancing the therapeutic effect. The dual effect of cold compress and drug penetration meets the user's need for rapid itch relief and soothing. In practical applications, the user simply needs to pre-cool the cold compress cloth 13 and insert it into the housing 1 to achieve combined treatment of cold compress and drug penetration through the massager. For example, in cases of skin itching caused by mosquito bites in summer, the user can place an appropriate amount of anti-itch medication into the medicine box 10, and through the massager's cold compress and vibration functions, quickly relieve itching and promote drug absorption.

[0026] The working principle of this utility model is as follows: S1 The user pre-cools the cold compress 13 and inserts it into the housing 1, and puts an appropriate amount of medicine into the medicine box 10. S2 The bidirectional motor 17 is started. The two output ends of the motor drive the worm gear 20 to rotate through the coupling. The worm gear 20 is meshed with the worm wheel 18, transmitting power to the drive shaft 23. S3 When the drive shaft 23 rotates, the drive gear 19 fixed outside it drives the driven gear 25 to rotate, thereby distributing power to the driven shaft 26. S4 The rotation of the driven shaft 26 drives the connecting plate 11 and the cam 9 to move. The cam 9 pushes the massage touch 3 to move along the circular hole trajectory to achieve multi-directional massage. S5 At the same time, the rotation of the drive shaft 23 drives the vibration ring and the protrusion 24 on its outer circumference to move. The interaction between the protrusion 24 and the inner wall of the vibration frame 27 produces a vibration effect. S6 The drug enters the drug delivery channel through the drug delivery block 16 of the drug delivery box 10, and is evenly distributed to the four telescopic covers 12 through the drug delivery channel. Finally, it penetrates into the drug-permeable plate 14 and acts on the skin surface through the drug-permeable holes 15. S7 The cold compress 13 lowers the local skin temperature through its low temperature properties, relieving inflammation and itching. At the same time, in conjunction with the drug penetration function, it achieves a rapid antipruritic and soothing effect.

[0027] This utility model's multifunctional integrated design makes it suitable for various skin care and massage needs in multiple scenarios. Whether for daily home use or professional treatment in medical institutions, this utility model provides an efficient and convenient solution. For example, in cases of muscle soreness after exercise, users can relieve fatigue through vibration and cold compress functions; in cases of skin allergies or inflammation, users can accelerate recovery through drug penetration and cold compress functions. This multifunctional cold compress vibration anti-itch massager not only enhances the user experience but also expands the application range of massagers, possessing broad market prospects and technological value.

[0028] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structures or equivalents made based on the description and drawings of this utility model are not permitted. Any changes to the process, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this utility model.
