Description

Technical Field

[0001] This invention relates to the field of massager technology, specifically to a portable simulated massager. Background Technology

[0002] Currently, people face significant pressure from various sources and live at a fast pace, leading many to experience frequent back pain. However, going out for a massage is quite expensive, so most people choose to endure it. Over time, minor ailments can develop into major problems. This highlights the importance of inventing a portable and practical massager.

[0003] Regarding massagers, application publication number CN104042433 A discloses a massager, specifically including a frame, a height adjustment mechanism mounted on the frame, and a massage component mounted on the height adjustment mechanism. The height adjustment mechanism includes a movable seat that moves up and down along a guide rail, a power source for driving the movable seat to move up and down, or the height adjustment mechanism includes two lead screws that rotate vertically on the frame via bearings, a power device for driving the lead screws to rotate, and a movable seat threadedly connected to the two lead screws. The massage component includes a first track mounted on the movable seat, a first sliding seat slidably mounted on the first track, a second track mounted on the first sliding seat, a second sliding seat slidably mounted on the second track, a massage head fixed on the second sliding seat, and a motor fixed on the movable seat. Both the first and second sliding seats have opposing circular holes, within which circular sliders are rotatably mounted. One-way bearings are positioned eccentrically on the circular sliders, and the one-way bearings on the two circular sliders rotate in opposite directions. The output shaft of the motor passes through the two one-way bearings. The first track is horizontally positioned, and the first and second tracks are perpendicular to each other. The massage head includes a guide sleeve, a guide post with an arc-shaped outer end that slides inside the guide sleeve, and a spring disposed between the guide post and the guide sleeve.

[0004] However, the aforementioned massagers also have some drawbacks. For example, the complex structure of the massage heads makes manufacturing difficult and may lead to component damage, thus reducing their lifespan. Furthermore, the massagers require pre-fixation before use. This means the massage heads are always directly facing the body, which can cause problems on curved areas like the neck or shoulders. Users often need to adjust their posture to ensure accurate pressure, making it inconvenient and illogical to use. The fixed design also occupies space, making them inconvenient to carry. Additionally, the protruding massage heads pose a safety hazard, as they could be bumped or knocked over during use. Summary of the Invention

[0005] This invention provides a portable simulated massager. Its massage components consist only of springs and massage heads, simplifying the structure and making manufacturing very convenient, while also extending its lifespan. Furthermore, the cooperation between the various support areas and the massage heads allows the massage heads to be easily pressed onto the human body without pre-fixing the massager's position. It also boasts advantages such as portability, compactness, and ease of use, making it highly practical.

[0006] Therefore, the present invention provides a portable simulated massager, comprising:

[0007] The system comprises a housing and a linear reciprocating mechanism, the latter installed inside the housing. The outer surface of the housing is a convex arc-shaped surface, and the inner outer surface has a perforation whose shape matches the movement trajectory of the massage component. The massage component includes a spring and a massage head. The outer surface of the massage head is a continuous, smooth, and convex arc-shaped surface that can form surface contact with human skin. The first end of the spring is connected to the output end of the linear reciprocating mechanism, and the second end extends outward from the perforation away from the first end, forming an outwardly convex spatial shape. The massage head is located on the outer surface of the second end of the spring, with its working surface facing away from the housing. The massage component can achieve linear movement driven by the linear reciprocating mechanism, and when the massage component performs linear movement, the massage head can apply periodic pressure to the human skin, simulating the pressure of a human hand.

[0008] The above settings simplify the structure of the massage components and make the massager very convenient to use.

[0009] Furthermore, at least two arched support areas are evenly distributed on both sides of the first end of the inner outer surface of the housing. These two support areas mimic the shape of a fingertip and also function as a pressure point on the human body. The support areas can form a stable three-point support structure with the massage component on the human body. Furthermore, the spring piece includes a connecting section and an arc-shaped section. The spring piece is connected to the connecting section and the arc-shaped section sequentially from the first end to the second end. The connecting section is straight and connected to the output end of the linear reciprocating mechanism. The massage head is located at the end of the arc-shaped section, and the end of the arc-shaped section is convex to avoid scratching the skin. The arc-shaped section gradually bends and extends away from the inner outer surface of the housing from the connection point with the connecting section, forming a continuous arc-shaped structure. This design allows the massage head to provide comfortable pressure when massaging the skin.

[0010] The device further includes a controller; the controller establishes a communication connection with the linear reciprocating mechanism via a wire or wireless means, and the controller is located on the outside of the housing; the controller is equipped with operating components for adjusting the massage stroke, massage frequency, and working time, and also has a switch function. These features facilitate convenient control of the massager.

[0011] The linear reciprocating mechanism further includes: a motor and a lead screw. One end of the motor is fixedly connected inside the housing, and the lead screw is rotatably mounted inside the housing, with one end connected to the output shaft of the motor and the other end rotatably supported on the inner wall of the housing via a bearing seat. A slider is threadedly engaged with the lead screw through an internal threaded hole, and the first end of a spring is fixed to the top surface of the slider. Two sets of guide rods are provided, parallel to the lead screw and located on both sides of the lead screw, with both ends of the two guide rods fixed to the inner wall of the housing. The slider contains two sets of linear bearings, with two linear bearing sleeves in each set mounted on the two guide rods. Two sets of limit switches are provided, each set installed inside the housing and located on one side of the lead screw, with the two limit switches distributed along the moving direction of the slider. The sensing block is fixed to the slider and can be used to engage with the two limit switches respectively. This configuration allows for stable driving of the massage head within a certain range.

[0012] Furthermore, the outer side of the housing is provided with a detachable Velcro strap, which is a single strap with its two ends interlocking. This design allows for convenient securing of the massager using Velcro.

[0013] Furthermore, the outer side of the housing is also provided with two shoulder straps. Each side of the housing is provided with two first through holes for the shoulder straps to pass through, and each first through hole is provided with a positioning post for connecting the shoulder straps. The above configuration allows the user to easily control the position and direction of the massager when massaging the back, avoiding the user operating it with their hand in the opposite direction.

[0014] A protective sleeve is fitted over the outer side of the housing. This sleeve fits snugly around the housing and covers the spring contacts and massage head. The sleeve is made of wear-resistant mesh fabric, providing a non-slip effect and helping to stabilize the massager during operation. This design enhances massage comfort and also prevents accidental insertion of fingers or other body parts into the housing through the perforations, improving safety.

[0015] Furthermore, all four corners of the shell are curved to prevent bumps and knocks to the human body during use;

[0016] The first and second ends of the inner outer surface of the shell are both arched; the middle part of the inner outer surface of the shell is concave, so that the inner outer surface as a whole presents a shape that conforms to the curve of the human body, while providing deformation space for the spring and making the upper limit of the spring deformation controllable.

[0017] The shell is made of plastic materials such as ABS engineering plastic or PC engineering plastic, and is integrally molded by injection molding process.

[0018] Furthermore, the spring is made of 65 manganese steel sheet through heat treatment; the connection method between the spring and the massage head is one of the following: in-mold injection molding, with at least two connection holes pre-formed at the connection part of the spring; hot melt welding, with at least three hot melt pillars on the connection surface of the massage head, and a matching positioning hole on the spring at the corresponding position, forming a fixed connection with the positioning hole after the hot melt pillars melt; rotatable connection, with the massage head hinged to the second working end of the spring via a metal rotating shaft, allowing the massage head to rotate freely relative to the spring. These settings allow the spring and massage head to be configured in different ways.

[0019] Furthermore, the massage head is provided with one or at least two distributed sequentially along the moving direction of the spring piece.

[0020] Compared with existing technologies, the advantages of this invention are: 1. Since the massage component of this invention only includes a spring and a massage head, the structure of the massage component can be simplified and the production is very convenient. It also improves its service life to a certain extent. Of course, the overall structure of the massager is also very simple, with high reliability and simple processing. In addition, the structure of the spring and the massage head can mimic human fingers, so that it can always fit the skin during the massage without external interference and the output is stable.

[0021] 2. In use, this invention allows the user to directly lean against the support area and massage head. For example, when the user needs to lie down for a massage, first place the massager in a suitable position on the bed, and then the user leans against the massager. The massage head and the various support areas work together to form a three-point positioning structure on the human body. During the massage, due to the outer arc of the body, the massager does not need to be fixed in advance. If the body posture changes slightly, the massager will automatically adjust the angle between the body and the bed to follow the change in body posture using the external force exerted by the body. In this way, the pressure of the massage head is always perpendicular or nearly perpendicular to the human body surface. That is, it is not necessary to adjust the body posture or angle to align with and accommodate the massage head, thus achieving the effect of the massage head accommodating the user for adjustment. This is different from the solution used in the prior art where the user accommodates the massage head for adjustment.

[0022] 3. This invention also boasts advantages such as portability, compact size, and ease of use, making it suitable for daily commutes and use in various situations. Because the shell is flat, with a maximum thickness of no more than 60mm, users can relax by resting their upper body, including their head, against a chair back or lying flat on a bed while massaging their back, enhancing the massage effect. Furthermore, the spring can be embedded in the perforation during deformation, thus requiring neither the spring nor the massage head to protrude excessively from the shell. This results in a safer massage component compared to the more protruding massage heads in existing technologies.

[0023] 4. In the process of driving the massage component by the linear reciprocating mechanism, the elasticity of the spring allows the second end of the spring to continuously support the massage head. Moreover, when the massage head moves to an uneven position, such as a wrinkle on the user's clothing or a transition area between the shoulder and neck, or other areas with significant changes in body curvature, the massage head can compress the spring or expand it outward according to the uneven position. This ensures that the massage head can always comfortably press on the massage area, meaning that the massage head can automatically follow the curvature of the human body, thus preventing fluctuations in pressure and ensuring a very stable massage pressure, thereby guaranteeing the massage effect.

[0024] 5. This invention, through the combination of a spring plate and a massage head, changes the traditional massage method of massage components, simulating a basic massage technique, one of the traditional Chinese medicine therapies. The spring plate is similar to a finger, and the massage head is similar to the fingertip. Due to the elasticity of the spring plate, the massage head can always press vertically on muscle knots or acupoints or areas on the body surface. Driven by a linear reciprocating mechanism, the spring plate moves the massage head back and forth in one direction, simulating a real massage technique, thus achieving different effects. For example, if the massager is held vertically against the back, it can create effects such as finger pushing and kneading; while if the massager is held horizontally against the back, it can create a plucking massage effect. Of course, the support area can also simulate the shape of fingers to a certain extent during use, so as to press the skin. Attached Figure Description

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0042] The present invention provides a portable simulated massager with the following embodiments:

[0043] Example 1:

[0044] like Figures 1-9 As shown, a portable simulated massager includes: a housing 1, a linear reciprocating mechanism 2, and a massage component 3.

[0045] like Figures 1-4 As shown, the linear reciprocating mechanism 2 is installed inside the housing 1. The outer surface of the housing 1 is a convex arc surface, and a through hole 11 is provided on the inner surface. The shape of the through hole 11 is adapted to the movement trajectory of the massage component 3. The length of the through hole 11 is slightly greater than the movement stroke of the massage component 3, and the width is slightly greater than the width of the spring piece 31.

[0046] The massage component 3 includes a spring plate 31 and a massage head 32. The outer surface of the massage head 32 is a continuous, smooth, and convex arc surface that can form surface contact with human skin. The first end of the spring plate 31 is connected to the output end of the linear reciprocating mechanism 2, and the second end extends outward from the perforation 11 in a direction away from the first end, so that the spring plate 31 as a whole forms an outwardly convex spatial shape. The massage head 32 is located on the outer surface of the second end of the spring plate 31, and the working surface of the massage head 32 faces away from the housing 1. The massage component 3 can be driven by the linear reciprocating mechanism 2 to achieve linear movement, and when the massage component 3 is moving linearly, the massage head 32 can form a periodic pushing action on human skin that simulates the pressure of a human hand.

[0047] like Figures 1-2 As shown, at least two arched support areas 12 are evenly distributed on both sides of the first end of the inner outer surface of the housing 1. The two support areas 12 simulate the shape of a fingertip and also serve as a pressure point on the human body. The support areas 12 can be used to form a stable three-point support structure with the massage component 3 on the human body. In this embodiment, the support areas 12 can be set as two evenly distributed areas. In addition, the surface of the support area 12 is a convex arc shape to ensure comfort. Multiple annular anti-slip ridges can also be provided on the surface of the support area 12 to increase anti-slip performance.

[0048] During use, the support area 12 of the housing 1 and the massage head 32 can be placed against the human body to form a three-point positioning structure, thereby allowing the massager to be stably attached to the surface of the human body.

[0049] In summary, the massage component 3 of the present invention only includes a spring plate 31 and a massage head 32, which simplifies the structure of the massage component and makes it very convenient to manufacture. It also improves its service life to a certain extent. Of course, the overall structure of the massager is also very simple, with high reliability and easy processing. In addition, the structure of the spring plate 31 and the massage head 32 can mimic human fingers, so that it can always fit the skin during the massage without external interference and the output is stable. Moreover, during use, the user can directly lean against the support area 12 and the massage head 32 without needing to pre-fix the massager's position. For example, when the user needs to lean against the massager, they can first put on the massager and then sit back on the sofa. The massage head 32 and each support area 12 work together to form a three-point positioning structure on the human body. During the massage, the massager does not need to be pre-fixed. Instead, it obtains support and reaction force through the pressure between the outer arc surface of the body and the backrest. If the body posture changes slightly, the massager will automatically adjust the angle of the shell 1 and the backrest to follow the change in body posture using the external force exerted by the body. In this way, the pressure of the massage head is always perpendicular or nearly perpendicular to the human body surface, meaning that no adjustment is required. The body's posture or angle is adjusted to align with and accommodate the massage head 32, allowing the massage head to adjust to the user's needs. This differs from existing technologies where the user adjusts to accommodate the massage head. Specifically, the spring plate 31, in conjunction with the massage head 32, alters the traditional massage method, simulating a fundamental massage technique from traditional Chinese medicine. The spring plate 31 resembles a finger, and the massage head 32 resembles a fingertip. Due to the elasticity of the spring plate 31, the massage head 32 can always press vertically against muscle knots or acupoints or areas on the body surface. Driven by the linear reciprocating mechanism 2, the spring plate 31 moves the massage head 32 back and forth in one direction, simulating massage techniques such as finger pushing, kneading, and plucking, achieving a precise meridian massage effect. Furthermore, the support area 12 can also simulate the shape of fingers to some extent during use, facilitating pressure on the skin.

[0050] Therefore, this design eliminates the need for pre-fixed positioning of the massager. The massager can be positioned arbitrarily according to the user's needs, requiring only a suitable location to support the outer surface of the housing 1. It also boasts advantages such as portability, compact size, and ease of use, making it suitable for daily commutes and use in various situations. Furthermore, because the spring piece 31 is strip-shaped and can be embedded in the perforation 11 during deformation, it doesn't need to protrude too much from the housing 1. Similarly, the massage head 32 doesn't need to protrude too much from the housing 1. This results in better safety for the massage component 3 compared to the more protruding massage heads in existing technologies.

[0051] Specifically, during the process of the linear reciprocating mechanism 2 driving the massage component 3, since the spring plate 31 is elastic, the second end of the spring plate 31 can continuously support the massage head 32. Moreover, when the massage head 32 moves to an uneven position, such as a wrinkle on the user's clothing or a transition area between the shoulder and neck, or other areas with large changes in the body's curvature, the massage head 32 can compress the spring plate 31 or be pushed outward by the spring plate 31 according to the uneven position, so that the massage head 32 can always comfortably fit the massage area. That is, the massage head 32 can automatically follow the curvature of the human body, so that the pressure is not easily fluctuated, and the massage pressure is very stable, thereby ensuring the massage effect.

[0052] like Figure 3 , Figure 4 , Figure 7 and Figure 9 As shown, specifically, the spring piece 31 includes a connecting section 311 and an arc-shaped section 312. The spring piece 31 is connected to the connecting section 311 and the arc-shaped section 312 sequentially from the first end to the second end. The connecting section 311 is a nearly straight, low-curvature arc and is connected to the output end of the linear reciprocating mechanism 2. Specifically, it can be locked with bolts to ensure stability. The massage head 32 is located at the end region of the arc-shaped section 312, and the end of the arc-shaped section 312 is an outwardly convex arc to avoid scratching the skin. The arc-shaped section 312 gradually bends and extends away from the inner outer surface of the housing 1 from the connection point with the connecting section 311, forming a continuous arc structure. It can be seen that the connecting section 311 and the arc-shaped section 312 are not at a 90° angle. The gradually tilted design of the spring piece 31 ensures that the massage head 32 provides comfortable pressure when massaging the skin, and the transition is more natural.

[0053] like Figure 3 , Figure 4 , Figure 7 and Figure 9 As shown, when the massage head is subjected to force, the spring sheet deforms to generate pressing pressure. The connecting segment 311, which is furthest from the massage head, begins to deform first until it comes into contact with the slider. The area of ​​deformation and contact increases sequentially with the increase of pressing pressure. The width of the spring sheet 31 decreases sequentially from the first end to the second end. Under this design, because the area of ​​the connecting segment 311 is relatively large, the connection stability between the connecting segment 311 and the output end of the linear reciprocating mechanism 2 can be ensured. The arc segment 312 has a smaller width, and when the overall deformation of the spring sheet 31 is large, the arc segment 312 also begins to deform. The design of the spring sheet 31 narrowing sequentially plays a role in balancing the correspondence between elastic force and deformation amount.

[0054] Preferably, the device also includes a controller 5; the controller 5 establishes a communication connection with the linear reciprocating mechanism 2 via a wire or wireless means, and the controller 5 is disposed on the outside of the housing 1; the controller 5 is provided with operating components for adjusting the massage stroke, massage frequency, and working time, and also has a switch function. Therefore, by setting the controller 5, it can be used to directly control the massage stroke, massage frequency, working time, etc., which is very convenient to use. Specifically, the controller 5 can achieve a communication connection with the linear reciprocating mechanism 2 through a conductive wire.

[0055] In other embodiments, the massager may also include a protective cover (not shown), made of abrasion-resistant mesh fabric, which provides greater friction at the points or surfaces where the body contacts the human body or the backrest, facilitating stable anchoring and operation of the massager. The protective cover fits snugly around the housing 1, covering the spring 31 and the massage head 32. The protective cover prevents the massage head 32 from directly contacting the area to be massaged during movement; instead, the surface of the cover contacts the area, thus improving massage comfort to some extent. Furthermore, the protective cover covers the perforation 11, preventing fingers or other body parts from accidentally inserting into the housing 1 during use, thus improving safety.

[0056] like Figures 3-4 As shown, preferably, the linear reciprocating mechanism 2 includes: a motor 21 and a lead screw 22. One end of the motor 21 is fixedly connected to the inside of the housing 1, and the lead screw 22 is rotatably installed inside the housing 1, with one end connected to the output shaft of the motor 21 and the other end rotatably supported on the inner wall of the housing 1 through a bearing seat; a slider 23, which forms a threaded engagement with the lead screw 22 through its internal threaded hole, and the first end of the spring piece 31 is fixed to the top surface of the slider 23; and guide rods 24, which are provided in two sets, parallel to the lead screw 22 and located on both sides of the lead screw 22. Both ends of the two guide rods 24 are fixed to the inner wall of the housing 1. The slider 23 is equipped with two sets of linear bearings, and each set of two linear bearing sleeves is provided on the two guide rods 24. Specifically, the motor 21 is communicatively connected to the controller 5 to control the motor 21 to perform corresponding actions. Therefore, when the motor 21 drives the lead screw 22 to rotate, it can synchronously drive the slider 23 to make linear reciprocating motion. When the slider 23 moves, it can synchronously drive the spring 31 and the massage head 32 to make corresponding linear reciprocating motion in the perforation 11. In this way, the massage head 32 can perform the corresponding massage operation on the area to be massaged.

[0057] like Figures 3-4As shown, preferably, the linear reciprocating mechanism 2 further includes a limit switch 25 and a sensing block 26. The limit switch 25 is provided in two sets, and the two sets of limit switches 25 are respectively installed inside the housing 1 and located on one side of the lead screw 22. The two limit switches 25 are distributed along the moving direction of the slider 23. The sensing block 26 is fixed on the slider 23 and can be used to cooperate with the two limit switches 25 respectively. Therefore, by setting mutually cooperating limit switches 25 and sensing blocks 26, the sensing blocks 26 can be moved synchronously when the slider 23 moves. The main function of the limit switches 25 is to limit the forward and backward endpoints of the spring 31 and the massage head 32, preventing them from exceeding the preset travel. For example, when the motor 21 drives the slider 23 and sensing blocks 26 forward, the motor 21 stops immediately after the sensing block 26 is sensed by the first limit switch 25, which also stops the movement of the spring 31 and the massage head 32. Similarly, when the motor 21 drives the slider 23 and sensing blocks 26 backward, the motor 21 stops immediately after the sensing block 26 is sensed by the second limit switch 25, which also stops the movement of the spring 31 and the massage head 32.

[0058] like Figures 1-2 Furthermore, the four corners of the housing 1 are all arc-shaped transitions, so that the housing 1 can be used to adapt to the skin of the human body, with good fit and better use effect, avoiding bumps to the human body during use; of course, when the human body is against the backrest at different angles and against the massager, due to the good fit between the housing 1 and the human body, combined with the arc surface on the outer side of the housing 1, it can easily find a balance point automatically and stop stably at this point, so as to ensure the stable output of the massage head 32.

[0059] In addition, the first and second ends of the inner outer surface of the housing 1 are both arched; the middle part of the inner outer surface of the housing 1 is concave, so that the inner outer surface as a whole presents a shape that conforms to the curve of the human body, while providing deformation space for the spring 31, so that the upper limit of the deformation of the spring 31 is controllable; the housing 1 is made of plastic materials such as ABS engineering plastic or PC engineering plastic, and is integrally formed by injection molding process.

[0060] In this embodiment, the arching of the first end of the inner outer surface of the housing 1 is smaller than the arching of its second end.

[0061] like Figures 1-2 As shown, in order to ensure ease of use, the housing 1 is designed to be elongated in this embodiment. The perforation 11 extends along the length of the housing 1, and the movement direction of the spring 31 and the massage head 32 also corresponds to the movement along the length of the housing 1.

[0062] In this embodiment, the shell 1 is flat and its maximum thickness is less than 60mm. The overall design is very compact and easy to carry.

[0063] like Figures 1-9 As shown, preferably, in this embodiment, the massage head 32 can be configured as one or at least two sequentially distributed along the moving direction of the spring sheet 31, which can be configured according to actual needs. Specifically, when there are two massage heads 32, if the spring sheet 31 deforms less during the massage, the massage force will also be less, and the massage head 32 furthest from the slider 23 will mainly play a role. However, if the spring sheet 31 deforms more during the massage, the massage force will also increase, and both massage heads 32 will work simultaneously to share the pressure. Therefore, this is an adaptive structure formed by utilizing the deformation elasticity of the spring sheet 31.

[0064] The specific operating principle of this invention is described below to help you understand it:

[0065] First, place the massager in position. Then, the user's back rests against the massager, which is also placed against the support surface. The massage head 32 and each support area 12 are pressed against the area to be massaged, forming a three-point positioning structure. Next, start the motor 21, which drives the lead screw 22 to rotate and cause the massage head 32 to move linearly back and forth. During the movement of the massage head 32, if it encounters areas with significant changes in body curvature, such as wrinkles in the user's clothing or the transition area between the shoulder and neck, the massage head 32 can compress the spring plate 31 or be pushed outward by the spring plate 31 according to the unevenness, so that the massage head 32 can always comfortably fit the massage area. The massage intensity is stable and the massage effect is excellent, effectively simulating the precise massage effect of a manual massage. During use, the user can also adjust the posture as needed. In addition, different angles of the massager will produce different effects. For example, if the massager is held vertically against the back, the massage head 32 can be used to create effects such as finger pushing and kneading; while if the massager is held horizontally against the back, the massage head 32 can be used to create a plucking massage effect.

[0066] Example 2:

[0067] like Figure 12As shown, the difference between this embodiment and Embodiment 1 is that, in this embodiment, the outer side of the housing 1 is provided with a detachable Velcro strap 6. The Velcro strap 6 has one strand, and its two ends can be fastened together. Therefore, the Velcro strap 6 allows the massager to be easily fastened to a part of the body for convenient massage. For example, the user can use the Velcro strap 6 to fasten the massager to the thigh or calf. Of course, in this case, the massage head 32 and the support area 12 should also be pressed firmly against the thigh to allow sufficient space for the massage head 32 to massage the corresponding acupoints during movement. Then, pressing the controller 5 controls the movement of the massage head 32.

[0068] It should be noted that if the outer surface of the housing 1 is provided with a protective cover, the Velcro strap 6 can be directly installed on the protective cover.

[0069] The Velcro strap 6 can be installed by either directly fixing it to the housing 1 or the protective cover, or by directly abutting against the housing 1 or the protective cover for easy installation and removal.

[0070] Example 3:

[0071] like Figure 13 As shown,

[0072] Therefore, in summary, the difference between this embodiment and Embodiment Two is that, in this embodiment, the outer side of the housing 1 is also provided with two shoulder straps 4. Each side of the housing 1 is provided with two first through holes 13 for the shoulder straps 4 to pass through, and each first through hole 13 is provided with a positioning post 14 for connecting the shoulder straps 4; the two shoulder straps 4 are arranged symmetrically on the left and right. It should be noted that if a protective sleeve is provided on the outer surface of the housing 1, then two second through holes corresponding to the two first through holes 13 are also provided on each side of the protective sleeve. The shoulder straps 4 can pass through the second through holes and then enter the first through holes 13. Therefore, the use of the shoulder straps 4 allows people to carry the massager on their back using the two shoulder straps 4. Of course, at this time, the massage head 32 and each support area 12 still abut against the area to be massaged to form a three-point positioning structure. Then the motor 21 can drive the massage head 32 to reciprocate to massage the back. During the massage, the position of the massage head 32 can be adjusted by adjusting the two shoulder straps 4, and fixed-point massage can be performed after finding a suitable position. In addition, in order to make the massager usable by all kinds of people, it is necessary to set the two shoulder straps 4 to be adjustable in length so that the tightness is more suitable when the user wears the massager on his back.

[0073] Example 4:

[0074] like Figures 6-9As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the spring 31 and the massage head 32 are made of metal and plastic respectively, using in-mold injection molding, hot melt welding, ultrasonic welding, or adhesive bonding. Since the plastic massage head 32 itself has a certain degree of deformability, it is less likely to cause excessive friction on the protective cover during massage, thus preventing damage to the protective cover due to excessive friction, and thus protecting the protective cover. As a preferred embodiment, the spring 31 is preferably made of 65 manganese steel sheet after heat treatment. However, those skilled in the art should know that other materials can be chosen, as long as they can be used normally; no further examples will be given here.

[0075] In addition, in this embodiment, regarding the width setting of the spring piece 31, the width of the connecting section 311 of the spring piece 31 is approximately 30-35mm, while the width of the end of the arc-shaped section 312 is approximately 14-20mm. The specific data mentioned above can be selected according to the thickness of the spring piece 31, which will not be elaborated here.

[0076] Example 5:

[0077] like Figures 1-5 As shown, the difference between this embodiment and Embodiment 4 is that both the spring 31 and the massage head 32 are made of a single piece of metal. This allows the spring 31 and the massage head 32 to be directly molded using a single-piece mold, making manufacturing simple, convenient, and robust. Furthermore, using metal materials for the spring 31 and the massage head 32 helps ensure their lifespan.

[0078] Example 6:

[0079] In this embodiment, the difference from embodiment five is that when the massage head 32 is metal, its outer surface can also be provided with an enamel layer (not shown in the figure) or a dip-coating layer (not shown in the figure), which can ensure the smoothness of the surface of the massage head 32, thereby reducing the frictional impact of the massage head 32 on the protective cover when it moves, and making the protective cover more durable.

[0080] Example 7:

[0081] like Figure 10 and Figure 11As shown, the difference between this embodiment and embodiments four, five, and six is ​​that in this embodiment, the massage head 32 is rotatably mounted on the spring plate 31 via a pivot 33. The specific installation method is as follows: first, a baffle (not shown in the figure) is set on both sides of the spring plate 31; then, the two ends of the pivot 33 of the rotatable massage head 32 are rotatably mounted on the two baffles respectively. Furthermore, regarding the materials used for the massage head 32 and the spring plate 31, the spring plate 31 is made of metal, while the massage head 32 is made of either metal or plastic. Therefore, with the above arrangement, the rotatable massage head 31 can move more smoothly, and when a protective cover is provided, the frictional wear between the massage head 31 and the protective cover can be reduced, thereby improving the service life of the massage head 31.

[0082] It should be noted that all electrical components mentioned in this article are connected to an external main controller, 220V AC mains power, and DC power. The main controller can be a conventional known device such as a computer for control. The specific implementation of this disclosure omits detailed descriptions of known functions and components. To ensure device compatibility, the operating methods used are consistent with the parameters of commercially available instruments.

[0083] In summary, the above description is merely a preferred embodiment of the technical solution of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
