Description

Technical Field

[0001] This invention relates to the field of facial muscle rehabilitation massage equipment technology, and in particular to a facial muscle massage and recovery device. Background Technology

[0002] The masseter, cheek, periorbital, and mandibular muscles are key functional muscle groups in the face, commonly used in rehabilitation after facial paralysis, post-operative muscle repair after maxillofacial surgery, relaxation of facial muscle strain, and daily facial tightening therapy. The physiological structure, tolerance, and rehabilitation needs of different facial muscle areas vary significantly: the masseter muscle is thick and requires strong, deep kneading and pressing; the cheek muscles are suitable for moderate-intensity, soothing kneading and relaxation; the periorbital muscles have thin, delicate skin and are only suitable for gentle, micro-vibration soothing modes; and the mandibular muscles require targeted, small-amplitude lifting and shaping massage.

[0003] Application number CN202323051371.6 discloses a facial muscle auxiliary massage device, including a mounting plate. The outer wall of the mounting plate has a threaded groove and a limiting hole arranged in a ring array around its perimeter, with the limiting hole located outside the threaded hole. It also includes an adjustment component screwed onto the inner wall of the threaded hole. A wearing component is fixedly connected to one side of the outer wall of the mounting plate. The adjustment component includes a threaded rod screwed onto the inner wall of the threaded hole. A U-shaped handle is fixedly connected to the outer wall of one end of the threaded rod. By adjusting the component, when the patient feels that the L-shaped massage cushion is applying too much or too little pressure to the facial muscles, the threaded rod can be rotated. When the threaded rod is rotated, the forward or backward movement of the compression component can be adjusted, making it convenient for the L-shaped massage cushion to be adjusted to comfortably fit the user's face and ensuring the effectiveness of use.

[0004] Based on the above patent search and understanding of the application of existing facial muscle massage and recovery devices: 1. Existing traditional facial massage recovery devices generally adopt an integrated centralized drive structure, in which all massage heads of the whole machine share the same set of drive mechanisms for transmission. This makes it impossible to automatically adjust the massage pressure according to the muscle area and the user's tolerance, which can easily lead to problems such as excessive pressure damaging muscles or insufficient pressure failing to achieve the recovery effect. 2. The massage head does not fit the facial contour well and is prone to shifting or tilting during adjustment. It lacks an adaptive angle adjustment and automatic reset structure, making it difficult to ensure that the massage head always fits the face stably.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a facial muscle massage and recovery device in order to achieve a more practical purpose. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a facial muscle massage and recovery device. This addresses the common issue that existing traditional facial massage and recovery devices typically employ an integrated, centralized drive structure, where all massage heads share the same drive mechanism for transmission. This makes it impossible to automatically adjust massage pressure based on muscle location and user tolerance, leading to problems such as excessive pressure damaging muscles or insufficient pressure failing to achieve the desired recovery effect. Furthermore, the massage heads often have poor conformity to facial contours, easily shifting or tilting during adjustment, lacking adaptive angle adjustment and automatic reset mechanisms, making it difficult to ensure the massage heads consistently maintain a stable fit to the face.

[0007] This invention provides a facial muscle massage and recovery device, specifically comprising: a main body mask; four massage structure positioning frames are provided on both the left and right sides of the main body mask, and the eight massage structure positioning frames are respectively set on the main body mask corresponding to the masseter muscle, cheek muscle, periorbital muscle and mandibular muscle, and each massage structure positioning frame is equipped with a disassembly cover; The inner wall of the disassembly cover is equipped with a miniature electric push rod. A miniature motor is fixedly installed at the bottom of the miniature electric push rod. The output shaft of the miniature motor is fixedly connected to the middle of the top of the adjustment frame. A drive motor is fixedly installed on the outer circumference of the adjustment frame. The output shaft of the drive motor rotates and extends into the interior of the adjustment frame and is fixedly connected to a bevel gear. A bevel gear ring is rotatably connected to the inner bottom wall of the adjustment frame. A spiral limiting rail is opened at the bottom of the bevel gear ring. The top edge of the bevel gear ring meshes with the bevel gear. Three sliding grooves are provided on the bottom outer wall of the adjustment frame. The three sliding grooves of the adjustment frame are distributed in a Y shape. An adjustment slider is slidably connected in each of the three sliding grooves of the adjustment frame. An arc groove is provided at the top of each adjustment slider. The arc grooves of the three adjustment sliders mesh with the spiral limiting rail of the bevel gear ring. The massage structure positioning frame is equipped with a wireless power transmission module, and the drive motor itself is equipped with a wireless power receiver module and a wireless control module.

[0008] Furthermore, a transmission frame is provided at the bottom of the adjusting slider. The inner end of the bottom of the transmission frame is hinged to the top of the inclined frame. A telescopic reset pressure sensor is hinged to the outer end of the bottom of the transmission frame. The other end of the telescopic reset pressure sensor is hinged to the middle outer wall of the inclined frame. A transition ball head is provided at the bottom of the inclined frame. The telescopic reset pressure sensor itself is equipped with a wireless power supply receiving module two and a wireless sensing transmitting module. The wireless power supply transmitting module wirelessly transmits power to the wireless power supply receiving module one and the wireless power supply receiving module two through magnetic resonance coupling wireless transmission.

[0009] Furthermore, the ball head at the bottom of the adapter ball head is inserted into the inner top of the adapter cover, and a return spring is sleeved on the outer side of the adapter ball head rod, with the bottom of the return spring fitting against the top outer wall of the adapter cover.

[0010] Furthermore, the top of the outer wall of the adapter cover is provided with a threaded hole, and a limiting bolt is threaded into the threaded hole of the adapter cover. The inner end of the limiting bolt can abut against the outer wall of the ball head at the bottom of the adapter ball head. A massage head is fixedly installed at the bottom of each adapter cover, and a rotatable massage ball is provided at the bottom of the massage head.

[0011] Furthermore, a fixing strap is provided on the rear side of the main body mask of the device, an adjustment buckle is provided in the middle of the fixing strap, a power connection cable is provided at the bottom of the main body mask of the device, and a locking clip is provided at the bottom of the power connection cable.

[0012] Furthermore, the power connection cable is connected to the controller via a wiring harness. The locking clamp is located in the wiring harness connecting the locking controller and the power connection cable. The controller is equipped with a power cable, which electrically connects to the micro motor, micro electric push rod, and wireless power supply transmission module. The controller has a built-in wireless communication module, which wirelessly connects to the wireless control module and the wireless sensor transmission module.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses a miniature electric push rod to extend and retract, thereby driving the adjustment frame to rise and fall. This allows for precise adjustment of the distance and pressure between the massage head and the face. In conjunction with a telescopic reset pressure sensor, pressure signals are collected in real time and fed back to the controller, enabling automatic monitoring and control of massage pressure. This effectively avoids excessive massage force that could damage muscles, or insufficient force that could affect the relaxation effect of the masseter and cheek muscles, significantly improving massage safety and recovery efficiency.

[0014] 2. This invention drives a bevel gear to rotate via a drive motor. The bevel gear meshes and drives a bevel gear ring to rotate. The bevel gear ring drives three adjusting sliders to expand or contract synchronously along the groove of the adjusting frame via a bottom spiral limiting rail. This, in turn, adjusts the coverage of the massage head synchronously via the transmission frame and the inclined frame. This allows for two modes: concentrated kneading and extended relaxation, adapting to different facial sizes and muscle areas, resulting in a more comprehensive massage.

[0015] 3. The present invention uses a ball joint to connect the adapter ball head and the adapter cover, so that the massage head can adaptively deflect with the facial contours, and always keep the rollers of the massage head in contact with the skin to ensure that they do not deviate or hang in the air; the return spring provides elastic support and automatic return capability for the adapter structure, and the limiting bolt can adjust the rotation damping to prevent it from shaking due to being too loose or getting stuck due to being too tight.

[0016] 4. This invention eliminates all wire connections in the rotating parts by using a dual wireless structure of magnetic resonance coupling wireless power supply and wireless communication, thus completely solving the problem of tangling and breakage of the drive motor and sensor harness when the adjustment frame rotates. The use of short-range magnetic resonance coupling transmission can achieve stable power supply and high efficiency, thereby extending the service life of the device. Attached Figure Description

The inner end of the limiting bolt 313 can abut against the outer wall of the ball head at the bottom of the adapter ball head 311. A massage head 315 is fixedly installed at the bottom of each adapter cover 312, and a rotatable massage ball is provided at the bottom of the massage head 315.

[0025] In this embodiment, a fixing strap 102 is provided on the rear side of the main body mask 1 of the device, and an adjustment buckle 103 is provided in the middle of the fixing strap 102. The fixing strap 102 and the adjustment buckle 103 can quickly adapt to different head circumferences and are worn securely without slipping. A power connection cable 104 is provided at the bottom of the main body mask 1 of the device, and a locking clip 105 is provided at the bottom of the power connection cable 104.

[0026] Preferably, the power connection cable 104 is connected to the controller 2 via a wiring harness, and the locking clamp 105 locks the wiring harness connecting the controller 2 and the power connection cable 104. The locking clamp 105 is located at the interface between the power connection cable 104 and the controller 2 to prevent the wiring harness from loosening and causing power failure. The controller 2 is equipped with a power cable, and the power connection cable 104 is electrically connected to the micro motor 302, the micro electric push rod 301, and the wireless power supply transmission module 4. The controller 2 has a built-in wireless communication module 201, and the controller 2 is electrically connected to the wireless control module 342 through the wireless communication module 201 to realize the start, stop, forward and reverse adjustment control of the drive motor 304. The controller 2 is wirelessly connected to the wireless sensor transmission module 3102 through the wireless communication module 201 to receive the pressure parameters collected by the telescopic reset pressure sensor 310 in real time and process, display, and perform closed-loop control.

[0027] Among them, controller 2 is a 32-bit ARM core independent control host with a working voltage of DC12V and a rated power consumption of ≤24W. It is equipped with a 2.4-inch TFT color LCD screen and mode adjustment buttons. It can independently start and stop eight micro motors 302, eight micro electric push rods 301 and eight drive motors 304, and receive pressure signals transmitted by telescopic reset pressure sensor 310 in real time to realize independent zone control and real-time parameter display.

[0028] When using: In use, the main body mask 1 of the device is first securely worn and fixed on the user's face using the fixing strap 102 and the adjusting buckle 103, so that the massage head 315 accurately corresponds to the target muscle areas such as the masseter muscle, cheek muscle, periorbital muscle, and jawline muscle. The power cord of the controller 2 is connected to an external power source to provide a stable power supply for the controller 2 and the overall electrical components. Then, the micro motor 302 is started by the controller 2, and the output shaft of the micro motor 302 begins to rotate. The adjusting frame 303, drive motor 304, bevel gear 305, bevel gear ring 306, adjusting slider 307, transmission frame 308, inclined frame 309, telescopic reset pressure sensor 310, adapter ball head 311, adapter cover 312, limiting bolt 313, reset spring 314, and massage head 315 operate synchronously and driven by the controller, so that the three massage heads 315 under each adjusting frame 303 perform continuous and stable massage treatment on the facial muscles at the designated locations. When pressure adjustment of the massage area is required, the micro electric push rod 301 can be controlled by the controller 2 to perform a telescopic action. The micro electric push rod 301 drives the micro motor 302 to move, thereby adjusting the adjustment frame 303 to move closer to or further away from the face, adjusting the distance between the massage head 315 and the face. When the adjustment frame 303 moves closer to the face, the inclined frame 309 and the transmission frame 308 rotate relative to each other, the telescopic reset pressure sensor 310 is compressed and contracted, and wirelessly interacts with the wireless sensing and transmitting module 3102 through the wireless communication module 201, feeding back the pressure data to the controller 2 in real time, so as to realize the precise monitoring and control of massage pressure.

[0029] This invention employs a ball joint design between the adapter ball head 311 and the adapter cover 312 to ensure that the three balls at the bottom of the massage head 315 always closely conform to the user's facial contours, preventing problems such as displacement, tilting, or suspension of the massage head 315 during pressure adjustment and massage. Furthermore, by using the screw-on fine-tuning mechanism of the limiting bolt 313, the rotational damping between the adapter ball head 311 and the adapter cover 312 can be flexibly adjusted to prevent excessive rotational sensitivity from causing wobbling, or insufficient sensitivity from causing poor fit. The present invention uses a return spring 314 sleeved on the outside of the rod of the adapter ball head 311 to provide elastic support when the massage head 315 is in contact with the face and bends and tilts with the adapter ball head 311; after the massage head 315 is removed from the face, the return spring 314 uses its own elasticity to return the adapter ball head 311 and the adapter cover 312 to the initial position, ensuring the positioning accuracy of the next massage.

[0030] In this invention, the controller 2 is wirelessly connected to the wireless control module 342 via the wireless communication module 201 to control the start, stop, forward and reverse rotation of the drive motor 304. After the drive motor 304 is started, the output shaft of the drive motor 304 drives the bevel gear 305 to rotate. The bevel gear 305 meshes with the bevel gear ring 306 to drive the bevel gear ring 306 to rotate. The spiral limiting rail at the bottom of the bevel gear ring 306 cooperates with the arc-shaped groove at the top of the three adjusting sliders 307, causing the three adjusting sliders 307 to expand outward or contract inward synchronously along the sliding groove of the adjusting frame 303. This allows for adjustment of the massage spacing of the three massage heads 315 under the same adjusting frame 303, achieving extended coverage massage and deep relaxation of the target area of ​​facial muscles, adapting to different facial sizes and muscle rehabilitation needs.
