Description

Technical Field

[0001] This application belongs to the field of massage equipment technology, and more specifically, relates to a massager. Background Technology

[0002] With the fast pace of life and increased health awareness, handheld massagers have become widely popular due to their ease of use and ability to massage and relax various parts of the body anytime, anywhere. Current handheld massagers typically rely on motors to drive the massage heads to generate vibrations. To enhance the massage effect, the motors often need to switch rapidly between forward and reverse directions. However, the high-frequency forward and reverse rotation of the motor generates a strong reverse force, which is directly transmitted to the hand, causing noticeable shaking when held. This not only reduces massage comfort but may also cause hand fatigue with prolonged use. Utility Model Content

[0003] The purpose of this application is to provide a massager to solve the technical problem in the prior art where handheld massagers cause hand-held parts to shake and feel uncomfortable to hold due to the rapid forward and reverse switching of the motor.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: A massager is provided, comprising a housing, a drive component, a massage head assembly, a main board, and a detection module; the drive component is disposed within the housing; the massage head assembly is connected to the drive component; the main board is electrically connected to the drive component, and the drive component is capable of driving the massage head assembly to rotate in both forward and reverse directions; the detection module is disposed on the outside of the housing and faces the massage area; the detection module is used to detect whether the massage assembly contacts the massage area and provides feedback to the main board to control the rotational speed of the drive component. When the massage head assembly contacts the massage area, the drive component rotates at a first rotational speed; when the massage head assembly separates from the massage area, the drive component rotates at a second rotational speed, wherein the first rotational speed is greater than the second rotational speed.

[0005] Furthermore, the detection module is used to measure the distance from the detection module to the massage area and feed it back to the motherboard to control the rotation speed of the drive component; when the distance from the detection module to the massage area is equal to the distance from the detection module to the massage head assembly, the drive component rotates at the first rotation speed; when the distance from the detection module to the massage area is greater than the distance from the detection module to the massage head assembly, the drive component rotates at the second rotation speed.

[0006] Furthermore, the massager also includes a fixing member connected to the housing, and the driving member is mounted on the fixing member; an elastic pad is provided between the driving member and the fixing member.

[0007] Furthermore, the fixing member is provided with a mounting groove, and an elastic element is provided in the mounting groove; the housing is provided with a mounting protrusion, and the mounting protrusion is inserted into the elastic element.

[0008] Furthermore, the detection module includes a ring circuit board and multiple detection sensors. The ring circuit board is mounted on the outside of the housing, and the multiple detection sensors are distributed in a circular array on the ring circuit board and face the massage area. The massage head assembly can pass through the ring circuit board and connect to the drive component.

[0009] Furthermore, the massager also includes a cover plate connected to the housing, and the detection module is clamped between the cover plate and the housing; the shape of the cover plate matches the shape of the annular circuit board to avoid the massage head assembly; the cover plate is provided with a clearance hole corresponding to the position of the detection sensor, and the clearance hole is used to avoid obstructing the detection sensor.

[0010] Furthermore, the fixing member is provided with a first detection member, and the output end of the driving member is provided with a second detection member. The second detection member can rotate with the rotation of the output end, and the second detection member is arranged opposite to the first detection member.

[0011] Furthermore, the massage head assembly includes a massage head body and a massage head holder, the massage head body and the massage head holder are snapped together, and the massage head holder is connected to the drive component.

[0012] Furthermore, the massage head body is provided with a first magnetic attraction component, and the massage head fixing frame is provided with a second magnetic attraction component; the first magnetic attraction component and the second magnetic attraction component are magnetically connected.

[0013] Furthermore, of the massage head body and the massage head fixing frame, one is provided with multiple positioning blocks and the other is provided with multiple positioning slots; the positioning slots are arranged in a one-to-one correspondence with the positioning blocks, and the positioning blocks are engaged with the positioning slots.

[0014] The beneficial effects of the massager provided in this application are as follows: Compared with the prior art, this application, by setting up a detection module, can monitor in real time whether the massage head assembly is in contact with the massage area. When the massage head assembly contacts the massage area, the detection module feeds a signal back to the main board, which then controls the drive component to rotate at a first speed. Since the first speed is greater than the second speed, this effectively increases the speed of the drive component, thus ensuring the massage intensity and effect. When the massage head assembly separates from the massage area, the main board, based on the feedback from the detection module, controls the drive component to switch to the second speed, which effectively reduces the speed of the drive component. This design effectively avoids ineffective high-speed operation of the drive component when it is not in operation, reduces unnecessary vibration caused by rapid forward and reverse rotation of the motor, thereby significantly improving the stability of the handheld part, improving the user's grip comfort, and also reducing energy consumption and extending the service life of the massager.

Therefore, they should not be construed as limitations on this application.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] Please refer to the following: Figure 1 and Figure 2The massager provided in this application embodiment will now be described. The massager includes a housing, a drive unit 100, a massage head assembly, a main board 200, and a detection module 300. The drive unit 100 is disposed within the housing. The massage head assembly is connected to the drive unit 100, and the drive unit 100 can drive the massage head assembly to rotate in both forward and reverse directions. The main board 200 is electrically connected to the drive unit 100. The detection module 300 is disposed on the outside of the housing and faces the massage area. The detection module 300 is used to detect whether the massage head assembly is in contact with the massage area and provides feedback to the main board 200 to control the rotational speed of the drive unit 100. When the massage head assembly contacts the massage area, the drive unit 100 rotates at a first rotational speed. When the massage head assembly separates from the massage area, the drive unit 100 rotates at a second rotational speed, where the first rotational speed is greater than the second rotational speed.

[0023] Compared with the prior art, the massager provided in this application, by setting a detection module 300, can monitor in real time whether the massage head assembly is in contact with the massage area. When the massage head assembly contacts the massage area, the detection module 300 feeds a signal back to the main board 200, which then controls the drive component 100 to rotate at a first speed, which is greater than a second speed, effectively increasing the speed of the drive component and ensuring the massage intensity and effect. When the massage head assembly separates from the massage area, the main board 200, based on the feedback from the detection module 300, controls the drive component 100 to switch to a second speed, effectively reducing the speed of the drive component 100. This design effectively avoids the ineffective high-speed operation of the drive component 100 when it is not in operation, reduces unnecessary vibration caused by the rapid forward and reverse rotation of the motor, thereby significantly improving the stability of the handheld part, improving the user's grip comfort, and also reducing energy consumption and extending the service life of the massager.

[0024] In this embodiment, the drive unit 100 can be a brushless motor; the forward and reverse rotation angle of the brushless motor is adjustable and set, and its forward and reverse rotation switching response speed is fast, which can accurately realize the speed and angle control in different modes, further improving the flexibility and effectiveness of massage.

[0025] Compared to traditional brushed motors, brushless motors eliminate the mechanical noise caused by carbon brush friction during operation, significantly reducing noise interference during massage and creating a quieter massage environment for users. Simultaneously, brushless motors offer higher operating efficiency and stability, maintaining consistent power output while switching between various massage modes, ensuring precise control of massage intensity and enhancing the consistency of the massage experience. Their lifespan is also relatively longer, reducing the frequency of product repairs or replacements due to motor failures and enhancing the overall durability of the massager.

[0026] In one embodiment of this application, the detection module 300 is used to measure the distance from the detection module 300 to the massage area and feed it back to the main board 200 to control the rotation speed of the drive unit 100; when the distance from the detection module 300 to the massage area is equal to the distance from the detection module 300 to the massage head assembly, the drive unit 100 rotates at a first rotation speed; when the distance from the detection module 300 to the massage area is greater than the distance from the detection module 300 to the massage head assembly, the drive unit 100 rotates at a second rotation speed.

[0027] This design allows the massager to automatically adjust the rotation speed of the drive unit 100 based on the actual distance from the massage area, resulting in a more precise and personalized massage experience. When the massage head assembly is close to the massage area, the drive unit 100 rotates at a first rotation speed, providing a stronger massage intensity; while when the massage head assembly is far from the massage area, the drive unit 100 rotates at a second rotation speed, which can be zero, thus avoiding ineffective massage movements and saving energy. Furthermore, the introduction of the detection module 300 enhances the massager's safety, preventing excessive pressure or injury caused by the massage head assembly being too close to the massage area, ensuring user comfort and safety during use.

[0028] In one embodiment of this application, please refer to the following: Figure 1 and Figure 4 The massager also includes a fixing member 400, which is connected to the housing, and a driving member 100 is mounted on the fixing member 400; an elastic pad 500 is provided between the driving member 100 and the fixing member 400.

[0029] In this embodiment, by adding an elastic pad 500 between the driving component 100 and the fixing component 400, the buffering characteristics of the elastic pad 500 can absorb some of the vibration energy generated when the driving component 100 is operating, thereby weakening the transmission path of vibration to the fixing component 400 and the housing. The elastic pad 500 can be made of materials with good elasticity and damping properties, such as silicone or rubber. Its thickness and hardness can be adjusted according to the actual vibration conditions to achieve the best vibration reduction effect. When the driving component 100 is fastened to the fixing component 400 by bolts or clips, the elastic pad 500 is tightly clamped between the two, which does not affect the stable installation of the driving component 100, and can buffer the radial and axial vibration of the driving component 100 in real time, further reducing the overall vibration amplitude of the massager and improving the user's grip stability.

[0030] In one embodiment of this application, please refer to the following: Figure 3 and Figure 4 The fixing member 400 is provided with a mounting groove, and the elastic member 600 is provided in the mounting groove; the housing is provided with a mounting protrusion, which is inserted into the elastic member 600.

[0031] In this embodiment, an elastic element 600 is provided in the mounting groove of the fixing member 400, and the mounting protrusion of the housing is inserted into the elastic element 600, forming a flexible connection structure between the fixing member 400 and the housing. The elastic element 600 is made of a material with high elasticity and fatigue resistance, which can play a buffering and vibration reduction role between the fixing member 400 and the housing. When the driving member 100 vibrates, the vibration is transmitted to the elastic element 600 through the fixing member 400. The elastic element 600 absorbs the vibration energy through its own elastic deformation, thereby effectively blocking the direct transmission of vibration to the housing. At the same time, the cooperation between the mounting protrusion and the elastic element 600 can also play a positioning role in the connection between the fixing member 400 and the housing, ensuring the accuracy of the assembly position of the two and avoiding the problem of vibration aggravation caused by assembly deviation. The inner hole size of the elastic element 600 is adapted to the outer diameter of the mounting protrusion, which can not only ensure the stability of the mounting protrusion after insertion, but also provide a certain amount of movement margin for the mounting protrusion during vibration, further improving the vibration reduction effect. This structural design is simple and reliable, and can significantly reduce the vibration amplitude of the shell without the need for additional complex vibration damping mechanisms, thereby improving the comfort of using the massager.

[0032] In one embodiment of this application, the fastener 400 and the housing are connected by fasteners, which pass through the mounting groove, the elastic member 600 and the mounting protrusion in sequence.

[0033] In this embodiment, the fasteners are rigid connectors such as bolts or screws. They pass sequentially through the mounting groove of the fixing member 400, the elastic member 600, and the mounting protrusion of the housing before engaging with a nut or threaded hole to achieve rigid locking between the fixing member 400 and the housing. During assembly, the tightening force of the fasteners will compress the elastic member 600 to a certain extent, thereby further enhancing the tightness of the fit between the elastic member 600 and the mounting groove and mounting protrusion, and improving the stability of the connection structure. At the same time, the compressed elastic member 600 can apply a reverse elastic force to the fasteners, effectively counteracting the tendency of the fasteners to loosen due to vibration, and ensuring the long-term reliability of the connection between the fixing member 400 and the housing. In addition, the fasteners can also limit the relative displacement of the fixing member 400 and the housing in the radial and axial directions, preventing the elastic member 600 from failing due to excessive deformation during long-term use, thereby ensuring the long-term stability of the vibration reduction effect of the flexible connection structure.

[0034] In one embodiment of this application, please refer to the following: Figure 1 and Figure 3 Specifically, the detection module 300 includes a ring circuit board 302 and multiple detection sensors 303. The ring circuit board 302 is mounted on the outside of the housing, and the multiple detection sensors 303 are distributed in a circular array on the ring circuit board 302 and face the massage area. The massage head assembly can pass through the ring circuit board 302 and connect to the drive unit 100.

[0035] The detection sensor 303 can be an infrared proximity sensor or an ultrasonic proximity sensor. Using multiple detection sensors 303 arranged in a circular array allows for monitoring the distance between the detection module 300 and the massage area from different angles, effectively expanding the distance sensing coverage and avoiding distance judgment errors caused by the limited detection angle of a single sensor. The design of the ring circuit board 302 provides a stable platform for the installation of multiple detection sensors 303, making its layout more compact and reasonable, while facilitating circuit connection with the main board 200, ensuring the stability and timeliness of signal transmission. The ring circuit board 302's ring structure design avoids obstructing the massage head assembly, facilitating its installation. When the massage head assembly approaches or contacts the massage area, multiple detection sensors 303 can simultaneously collect distance information and feed it back to the main board 200. The main board 200, through comprehensive analysis and judgment of multiple sets of data, can more accurately determine the real-time position of the massage head assembly, thereby more quickly and accurately controlling the rotation speed switching of the drive component 100, further improving the intelligent response speed and ease of use of the massager.

[0036] In one embodiment of this application, please refer to the following: Figure 1 and Figure 3 The massager also includes a cover plate 301, which is connected to the housing. The detection module 300 is clamped between the cover plate 301 and the housing. The shape of the cover plate 301 matches the shape of the annular circuit board 302 to avoid the massage head assembly. The cover plate 301 is provided with a clearance hole 311, which corresponds to the position of the detection sensor 303. The clearance hole 311 is used to avoid obstructing the detection sensor 303.

[0037] Specifically, the cover plate 301 is also designed to be annular, matching the shape of the annular circuit board 302. This ensures that the cover plate 301 can effectively clamp and fix the detection module 300, while avoiding interference with the installation and movement of the massage head assembly. The housing is provided with a mounting groove, in which the detection module 300 is placed. The cover plate 301 is connected to the housing at the mounting groove, and the detection module 300 is clamped between the cover plate 301 and the housing.

[0038] In this embodiment, the cover plate 301 is fixedly connected to the housing by clips or screws, firmly clamping the detection module 300 in the mounting slot to ensure that it will not shift or fall off due to vibration during the use of the massager. This installation method simplifies the assembly process of the detection module 300 and provides it with a stable working environment, avoiding interference from external factors on the detection accuracy.

[0039] The clearance hole 311 is precisely positioned to correspond to the sensing area of ​​the detection sensor 303. Its diameter is designed according to the detection range of the detection sensor 303, ensuring that the sensor 303 can transmit and receive sensing signals, such as infrared or ultrasonic signals, without obstruction through the clearance hole 311. The edges of the clearance hole 311 are rounded to avoid sharp structures causing reflection interference to the sensor signal, and also to prevent users from being scratched by the edges during use.

[0040] In one embodiment of this application, one end of the housing forms a handle, and the main board 200 is disposed in the handle; the housing is also provided with a button 201; the button 201 is electrically connected to the main board 200 and is used for the user to manually switch massage modes or adjust the rotation speed of the drive unit 100. A battery pack 202 is provided inside the handle, and the battery pack 202 is electrically connected to the main board 200 to provide working power for various electrical components such as the drive unit 100 and the detection module 300.

[0041] Specifically, the housing includes an upper shell 901 and a lower shell 901; the upper shell 901 and the lower shell 901 can be connected by a snap-fit ​​structure or screws to realize the detachable assembly of the housing, which facilitates the installation, maintenance and replacement of internal components.

[0042] In one embodiment of this application, please refer to the following: Figure 5 and Figure 6 The fixing member 400 is provided with a first detection member 701, and the output end of the driving member 100 is provided with a second detection member 702. The second detection member can rotate with the rotation of the output end, and the second detection member 702 is arranged opposite to the first detection member 701.

[0043] In this embodiment, the first detection element 701 and the second detection element 702 work together to form an effective detection mechanism for the rotational state of the drive element 100. When the output end of the drive element 100 rotates, the second detection element 702 rotates along with the output end. Since the second detection element 702 is positioned relative to the first detection element 701, the first detection element 701 can sense the positional or state changes of the second detection element 702 and transmit the relevant signals to the main board 200. Based on the received signals, the main board 200 can accurately determine parameters such as the rotation angle and rotational speed of the drive element 100, thereby achieving more precise control over the drive element 100. This detection mechanism helps improve the working stability and reliability of the massager, ensuring that the massager can operate stably according to the preset program and parameters, providing users with a more comfortable and effective massage experience.

[0044] Specifically, the first detection element 701 is a Hall element, and the second detection element 702 is a magnet. The Hall element detects the changes in the magnetic field generated when the magnet rotates and converts the detected magnetic field change signal into an electrical signal, which is then transmitted to the mainboard 200. Upon receiving the electrical signal, the mainboard 200 processes and analyzes it, calculating specific parameters such as the rotation angle and speed of the drive element 100 using a preset algorithm and program. Based on these parameters, the mainboard 200 can adjust the control commands to the drive element 100 in a timely manner, ensuring that the drive element 100 operates according to the set requirements. This guarantees that the massage intensity and frequency of the massager meet the user's personalized needs, further improving the massager's performance and effectiveness. Compared to setting up an encoder, the Hall element and magnet are less expensive to install and have a more compact structure, making them suitable for the limited installation space inside the massager.

[0045] In one embodiment of this application, the fixing member 400 has a through hole, and the first detection member 701 at least partially covers the through hole, corresponding to the second detection member 702. The driving member 100 is provided with a fixing block 101, which is used to fix the second detection member 702. This arrangement allows the first detection member 701 to sense the magnetic field changes of the second detection member 702 at a closer distance, thereby improving detection accuracy and sensitivity. The size of the through hole is slightly larger than the sensing area of ​​the first detection member 701 to provide sufficient installation space for the first detection member 701, while avoiding the shielding effect of the fixing member 400 on the magnetic field.

[0046] In one embodiment of this application, please refer to the following: Figure 4 and Figure 5 The massage head assembly includes a massage head body 801 and a massage head holder 802, which are snapped together. The massage head holder 802 is connected to the drive unit 100.

[0047] In this embodiment, the massage head body 801 and the massage head holder 802 are connected by a snap-fit ​​mechanism, which simplifies the assembly process and improves production efficiency. The connection design between the massage head holder 802 and the drive component 100 ensures that the power of the drive component 100 is stably transmitted to the massage head body 801, enabling the massage head body 801 to perform massage actions according to a preset trajectory. At the same time, this split structure facilitates the individual replacement or cleaning of the massage head body 801. When the massage head body 801 is worn or needs to be replaced with a different type of massage head, it is not necessary to disassemble the entire massage head assembly; simply remove the massage head body 801 from the holder, making the operation convenient.

[0048] In one embodiment of this application, please refer to the following: Figure 1 and Figure 4The massage head body 801 is provided with a first magnetic suction member 811, and the massage head fixing frame 802 is provided with a second magnetic suction member 821; the first magnetic suction member 811 and the second magnetic suction member 821 are magnetically connected.

[0049] In this embodiment, the magnetic attraction between the first magnetic member 811 and the second magnetic member 821 further enhances the stability of the connection between the massage head body 801 and the massage head mounting bracket 802, preventing the massage head body 801 from loosening or falling off during high-speed rotation. The magnetic connection also provides guidance and pre-fixation during assembly, allowing users to quickly align the massage head body 801 with the mounting bracket, improving assembly efficiency. Simultaneously, when the massage head body 801 needs to be disassembled, only a certain pulling force needs to be applied to overcome the magnetic attraction to remove it, making the operation effortless and preventing damage to the massage head body 801 or the mounting bracket, thus balancing connection reliability and disassembly convenience. The first magnetic member 811 and the second magnetic member 821 can be made of strong magnetic materials such as neodymium iron boron magnets, ensuring minimal magnetic attenuation during long-term use and guaranteeing the long-term stability of the connection structure.

[0050] In one embodiment of this application, of the massage head body 801 and the massage head fixing frame 802, one is provided with a plurality of positioning blocks 812 and the other is provided with a plurality of positioning grooves; the positioning grooves are provided in a one-to-one correspondence with the positioning blocks 812, and the positioning blocks are engaged with the positioning grooves.

[0051] In this embodiment, the positioning block 812 is set on the massage head body 801 as an example, and the corresponding positioning groove is set on the massage head fixing frame 802.

[0052] In this embodiment, the snap-fit ​​between the positioning block 812 and the positioning groove restricts the circumferential rotation of the massage head body 801 and the massage head mounting bracket 802, preventing the massage head body 801 from rotating on its own and ensuring that the massage head body 801 remains synchronized with the mounting bracket during rotation with the drive component 100. This avoids unstable massage force or structural wear caused by relative rotation. The cross-sectional shape of the positioning block 812 can be designed as rectangular, trapezoidal, or dovetail-shaped, etc. Correspondingly, the shape of the positioning groove matches the positioning block 812 to achieve a tight snap-fit ​​effect. Multiple positioning blocks 812 and positioning grooves are evenly distributed circumferentially along the massage head body 801 and the mounting bracket, which makes the force between the two more balanced and further improves the stability of the connection. During assembly, the user only needs to align the positioning block 812 with the positioning groove and apply axial pressure to quickly snap the massage head body 801 with the mounting bracket. The operation is simple and convenient, and it also facilitates subsequent disassembly and replacement.

[0053] It is understandable that the multiple positioning blocks 812 can have the same or different shapes. The different shapes of the positioning blocks 812, combined with the corresponding shaped positioning grooves, can prevent errors during assembly, avoiding functional malfunctions or structural interference after the massage head body 801 is connected to the mounting bracket due to incorrect installation orientation. For example, one positioning block 812 can be designed as a triangle, while the others are designed as rectangles, and the corresponding positioning grooves also use the same shape combination. This ensures that the user can only insert the massage head body 801 into the mounting bracket in the correct orientation, effectively reducing the assembly error rate and improving product reliability and user experience. This multi-shape positioning structure achieves error prevention through clever mechanical design without increasing assembly complexity. It is especially suitable for scenarios requiring frequent replacement of the massage head body 801, helping users complete the replacement operation quickly and accurately.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
