Description

Technical Field

[0001] This application relates to the technical field of massage equipment, and more particularly to a massage device. Background Technology

[0002] In the field of massage equipment, telescopic massage devices have received widespread attention and application because they can flexibly adjust the massage position and range to adapt to different user body parts and massage needs.

[0003] Currently, most telescopic massage devices on the market rely on guide rods to guide the extension and retraction process. While this method can guide the extension and retraction of the massage device to some extent, it suffers from significant stability defects. During the extension and retraction operation, due to the limited precision of the fit between the guide rod and related components, coupled with the vibrations and impacts generated during the massage, the guide rod is prone to wobbling and misalignment, resulting in unstable and inaccurate extension and retraction movements. This not only affects the comfort and effectiveness of the massage, preventing the massage intensity and position from accurately targeting the target area, but may also accelerate the wear and tear of internal components due to long-term unstable operation, reducing the device's lifespan.

[0004] Furthermore, existing telescopic massage devices using guide rods present significant installation challenges. The installation of the guide rods requires precise positioning and calibration to ensure accurate alignment with other components of the massage device. However, in actual installation, achieving ideal installation precision is often extremely difficult due to factors such as component machining errors and the assembly environment. This not only increases the difficulty and time cost of installation but also places high demands on the professional skills and experience of the installers. Moreover, once a deviation occurs in the guide rod installation, subsequent debugging and correction work is cumbersome, further impacting the production efficiency and product quality of the massage device. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a massage device that can solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, this application adopts the following technical solution: On one hand, a massage device is provided, comprising: a housing, a guide assembly, a drive assembly, and a massage head, wherein the guide assembly and the drive assembly are both disposed inside the housing, the guide assembly is connected to the massage head, and the drive end of the drive assembly drives the massage head to perform a telescopic massage action through the guide assembly; The guide assembly includes a main body, a sliding member, and a telescopic rod. The sliding member is slidably fitted onto the main body and is connected between the drive end of the drive assembly and the telescopic rod. The telescopic rod extends at least partially out of the housing and is connected to the massage head. Guide grooves are formed on both sides inside the main body, and guide portions that cooperate with the guide grooves are provided on both sides of the sliding member.

[0007] Furthermore, both the guide groove and the guide portion have circular cross-sections.

[0008] Furthermore, the main body has an opening at the end opposite to the massage head, and the opening allows the slider to slide into it.

[0009] Furthermore, a limiting part is provided at the end of the main body away from the opening. The limiting part is used to limit the movement stroke of the sliding member, and a through hole is provided on the limiting part for the telescopic rod to pass through.

[0010] Furthermore, both the main body and the sliding component are made of plastic.

[0011] Furthermore, the drive assembly includes a motor, an eccentric wheel, and a drive rod. The output shaft of the motor is connected to the eccentric wheel. One end of the drive rod is connected to the eccentric wheel, and the other end of the drive rod is connected to the sliding member.

The circuit board is installed inside the housing, and the operation button is installed on the outer wall of the housing. The operation button is electrically connected to the circuit board, and the circuit board is electrically connected to the drive assembly.

[0013] Furthermore, it also includes a base and a connecting rod, one end of which is movably connected to the base and the other end of which is movably connected to the housing.

[0014] Furthermore, the bottom of the base is provided with multiple adsorption disks arranged in an array.

[0015] Furthermore, a detachable connection structure is provided between the massage head and the telescopic rod. The detachable connection structure includes an elastic buckle provided at the end of the telescopic rod and a buckle groove provided in the massage head. The elastic buckle and the buckle groove are interference fit. A heating module is also embedded inside the massage head. The heating module is electrically connected to the circuit board. The surface of the heating module is covered with a thermally conductive silicone layer.

[0016] The beneficial effects of this application are as follows: On the one hand, in terms of guiding stability, the cooperation between the guide groove inside the main body and the guide parts on both sides of the sliding part provides a precise and stable guide for the telescopic movement of the massage head, effectively avoiding the shaking and offset problems caused by the guide rod in the prior art, enabling the massage head to perform telescopic massage movements accurately and smoothly, greatly improving the comfort and effect of the massage, ensuring that the massage force and position can be accurately applied to the target area, while reducing the wear of internal parts of the device caused by unstable operation, and extending the service life of the device.

[0017] On the other hand, in terms of ease of installation, the main body adopts an integrated molding design, which avoids the cumulative errors caused by assembling multiple parts.

Detailed Implementation

[0021] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] like Figures 1-5 As shown, this embodiment provides a massage device, including: a housing 1, a guide assembly 2, a drive assembly 3, and a massage head 4. The guide assembly 2 and the drive assembly 3 are both disposed inside the housing 1. The guide assembly 2 is connected to the massage head 4. The drive end of the drive assembly 3 drives the massage head 4 to perform telescopic massage actions through the guide assembly 2. The guide assembly 2 includes a main body 201, a sliding member 202, and a telescopic rod 203. The sliding member 202 is slidably fitted onto the main body 201 and is connected between the drive end of the drive assembly 3 and the telescopic rod 203. The telescopic rod 203 extends at least partially out of the housing 1 and is connected to the massage head 4. Guide grooves 2011 are formed on both sides inside the main body 201. Guide portions 2021 that cooperate with the guide grooves 2011 are provided on both sides of the sliding member 202.

[0025] Based on the above solution, the massage device provided in this embodiment effectively solves the problems of low guiding stability and inconvenient installation of telescopic massage devices in the prior art through a unique structural design. Regarding guidance, the main body 201 of the guide component 2 has guide grooves 2011 on both sides, and the sliding member 202 has guide portions 2021 on both sides corresponding to the guide grooves 2011. When the drive component 3 is activated, its drive end drives the sliding member 202 to slide on the main body 201. The guide portions 2021 and guide grooves 2011 closely cooperate, providing a precise guiding path for the movement of the sliding member 202, limiting the swaying and offset of the sliding member 202 in the non-telescopic direction, so that the sliding member 202 can only make stable linear movements along the direction set by the guide grooves 2011. The telescopic rod 203 connects the sliding member 202 and the massage head 4. The stable movement of the sliding member 202 is transmitted to the massage head 4 through the telescopic rod 203, thereby ensuring the stability and accuracy of the massage head 4 during telescopic massage movements.

[0026] In terms of ease of installation, the main body 201 adopts a one-piece molding design. The one-piece molding process ensures high consistency in dimensional and shape accuracy of all parts during manufacturing, avoiding cumulative errors caused by assembling multiple components. When installing the guide assembly 2 into the housing 1, there is no need for complex positioning and calibration operations on the main body 201; it can simply be placed in the appropriate position, greatly reducing installation difficulty, improving installation efficiency, and minimizing subsequent debugging and correction work due to installation deviations.

[0027] Furthermore, both the guide groove 2011 and the guide portion 2021 have circular cross-sections. Due to the symmetry of the circle, the contact between the guide portion 2021 and the guide groove 2011 is uniform regardless of its position within the guide groove 2011. During sliding, the force between the guide portion 2021 and the guide groove 2011 is evenly distributed across the entire contact surface, preventing jamming or uneven wear caused by excessive local force. Moreover, the circular structure results in lower rotational resistance for the guide portion 2021 within the guide groove 2011. When the slider 202 experiences minor lateral forces or angular deviations during movement, the guide portion 2021 can relatively flexibly fine-tune its position within the guide groove 2011, automatically adjusting to the optimal motion state, thereby ensuring that the slider 202 can slide continuously and smoothly on the main body 201.

[0028] Furthermore, the main body 201 has an opening 2012 at the end opposite to the massage head 4, which allows the sliding member 202 to slide into it. In terms of installation, this opening 2012 provides a convenient installation entry for the sliding member 202, allowing it to easily embed into the main body 201 and enabling the guide portion 2021 to cooperate with the guide groove 2011. This greatly simplifies the installation process, reduces installation difficulty, and improves installation efficiency, making it particularly suitable for large-scale production assembly and helping to improve production efficiency and reduce costs.

[0029] Meanwhile, a limiting part 2013 is provided at the end of the main body 201 facing away from the opening 2012. The limiting part 2013 is used to limit the movement stroke of the slider 202, and a through hole 2014 is provided on the limiting part 2013 for the telescopic rod 203 to pass through. The limiting part 2013 at the end of the main body 201 facing away from the opening 2012 plays a key role in limiting the stroke during the movement of the slider 202. When the driving assembly 3 continuously drives the slider 202 to move away from the opening 2012, the slider 202 will gradually approach the limiting part 2013. Once the slider 202 moves to the preset limit position, the limiting part 2013 will contact the slider 202, preventing the slider 202 from moving forward, thereby precisely limiting the movement stroke of the slider 202. The through hole 2014 on the limiting part 2013 for the telescopic rod 203 to pass through not only ensures that the telescopic rod 203 can extend and retract smoothly with the movement of the sliding member 202 without being obstructed by the limiting part 2013, but also allows the limiting part 2013 to independently limit the stroke of the sliding member 202. The two do not interfere with each other and together ensure the normal operation of the massage device.

[0030] It is worth mentioning that both the main body 201 and the sliding member 202 are made of plastic. Plastic materials possess a certain degree of flexibility and elasticity. When the sliding member 202 slides within the main body 201, even with minor processing errors or wear from long-term use, the flexibility of the plastic allows them to automatically adjust their contact state to a certain extent, reducing jamming caused by excessive gaps or friction. Furthermore, the relatively smooth surface of the plastic results in less friction during sliding, which helps the sliding member 202 move more smoothly within the main body 201, ensuring the continuity and stability of the massage head 4's telescopic movements.

[0031] In some embodiments, the drive assembly 3 includes a motor 301, an eccentric wheel 302, and a drive rod 303. The output shaft of the motor 301 is connected to the eccentric wheel 302. One end of the drive rod 303 is connected to the eccentric wheel 302, and the other end is connected to the slider 202. During operation of the massage device, the motor 301 starts as a power source, and its output shaft begins to rotate. Since the output shaft of the motor 301 is connected to the eccentric wheel 302, the rotational power of the motor 301 is transmitted to the eccentric wheel 302, causing the eccentric wheel 302 to rotate as well. The eccentric wheel 302 has an eccentric structure, meaning that its center of rotation does not coincide with its geometric center. During rotation, points on the eccentric wheel 302 at different distances from the center of rotation will perform circular motion with different radii of their trajectories. One end of the drive rod 303 is connected to the eccentric wheel 302. As the eccentric wheel 302 rotates, the end of the drive rod 303 connected to the eccentric wheel 302 will move in a circular motion around the center of rotation of the eccentric wheel 302. The other end of the drive rod 303 is connected to the slider 202. Since the slider 202 can only slide linearly within the main body 201, due to this motion restriction, the drive rod 303 converts the rotational motion of the eccentric wheel 302 into the power to push the slider 202 to make reciprocating linear motion within the main body 201. This power, in turn, drives the massage head 4 to perform telescopic massage actions via the telescopic rod 203.

[0032] In addition, the device includes a circuit board 6 and an operation button 5. The circuit board 6 is installed inside the housing 1, and the operation button 5 is installed on the outer wall of the housing 1. The operation button 5 is electrically connected to the circuit board 6, and the circuit board 6 is electrically connected to the drive assembly 3. The user issues an operation command by pressing the operation button 5 installed on the outer wall of the housing 1. Since the operation button 5 is electrically connected to the circuit board 6 installed inside the housing 1, when the operation button 5 is pressed, a corresponding electrical signal change is generated, and this electrical signal is quickly transmitted to the circuit board 6. The circuit board 6, as the electronic control core of the entire massage device, has signal processing and control functions. After receiving the electrical signal from the operation button 5, it analyzes and processes the signal according to a preset program and logic to determine the user's specific operational intention, such as turning on the massage device, adjusting the massage intensity, changing the massage mode, or turning off the device. Then, the circuit board 6 sends a corresponding control electrical signal to the drive assembly 3 based on the processing result. Because the circuit board 6 is electrically connected to the drive component 3, after receiving the control signal from the circuit board 6, the drive component 3 will adjust its working state according to the signal instructions, such as the speed and direction of the motor 301, and then drive the sliding part 202 and the massage head 4 to make corresponding changes through the eccentric wheel 302 and the drive rod 303, so as to realize the massage function expected by the user.

[0033] Optionally, the device also includes a base 7 and a connecting rod 8. One end of the connecting rod 8 is movably connected to the base 7, and the other end is movably connected to the housing 1. In the application of the massage device, the base 7 is typically placed on a support surface, providing a stable support foundation for the entire device. The design of the connecting rod 8, with one end movably connected to the base 7 and the other end movably connected to the housing 1, allows the housing 1 to move flexibly in multiple directions relative to the base 7. When the user uses the massage device, because the connecting rod 8 is movably connected to both the base 7 and the housing 1, the housing 1 can rotate and tilt within a certain range. For example, the user can manually adjust the angle and position of the housing 1 according to their desired body part and comfortable posture. The connecting rod 8 will rotate accordingly at the connection point between the housing 1 and the base 7, thus adapting to different usage angles and positional requirements, allowing the massage head 4 to more accurately target the massage area.

[0034] The base 7 has multiple adsorption plates 9 arranged in an array at its bottom. When the massage device is placed on a flat support surface such as a table or chair, the adsorption plates 9 at the bottom of the base 7 will make close contact with the support surface. Since the adsorption plates 9 are usually made of materials with a certain degree of flexibility and elasticity, under the pressure of the weight of the base 7 and the massage device, the adsorption plates 9 will undergo slight deformation, squeezing out the air inside. This creates a relatively sealed space between the adsorption plates 9 and the support surface, with an air pressure lower than the external atmospheric pressure. According to the principle of atmospheric pressure, the external atmospheric pressure will exert a downward pressure on the adsorption plates 9. This pressure will press the adsorption plates 9 tightly against the support surface, thereby providing a stable fixation for the entire massage device through the base 7, preventing the device from moving or tipping over due to vibrations generated by the operation of the drive component 3 or unintentional touches by the user during use.

[0035] Specifically, a detachable connection structure is provided between the massage head 4 and the telescopic rod 203. This detachable connection structure includes an elastic buckle at the end of the telescopic rod 203 and a buckle groove on the massage head 4. The elastic buckle and the buckle groove are interference-fitted. A heating module is also embedded inside the massage head 4, and the heating module is electrically connected to the circuit board 6. The surface of the heating module is covered with a thermally conductive silicone layer. In the massage device, when the massage head 4 needs to be installed on the telescopic rod 203, the user only needs to bring the massage head 4 close to the end of the telescopic rod 203, aligning the elastic buckle at the end of the telescopic rod 203 with the buckle groove on the massage head 4. Because the elastic buckle has a certain degree of elasticity, it will deform when subjected to external pressure. When the massage head 4 is pressed forcefully towards the telescopic rod 203, the elastic buckle is squeezed and gradually enters the buckle groove. Once the elastic buckle is fully inside the buckle groove, it uses its own elastic restoring force to form an interference fit with the buckle groove, thus firmly fixing the massage head 4 to the telescopic rod 203. When it is necessary to disassemble the massage head 4, the user applies a certain external force to pull the massage head 4 outward. At this time, the elastic buckle deforms again under the action of the pulling force and gradually disengages from the buckle groove, realizing the separation of the massage head 4 from the telescopic rod 203.

[0036] Circuit board 6 serves as the electronic control core of the massage device. When the user issues a command to activate the heating function via operation button 5, circuit board 6 receives the corresponding electrical signal and sends a control electrical signal to the heating module inside the massage head 4 according to a preset program. Upon receiving the electrical signal, the heating module begins operation, converting electrical energy into heat energy. The thermally conductive silicone layer has excellent thermal conductivity; it tightly covers the surface of the heating module, quickly and evenly conducting the heat generated by the heating module away, causing the surface temperature of the massage head 4 to rise uniformly, thus providing the user with a warm massage experience.
