Description

Technical Field

[0001] This invention relates to the field of massager technology, and in particular to a novel lifting massage head structure, massage mechanism, and walking massager. Background Technology

[0002] With increasing life pressures and growing physical fatigue, people need to use assistive tools to relieve fatigue. With the widespread application of mechanization and automation, various massagers that simulate manual massage have entered thousands of households, and massage devices have thus emerged.

[0003] Existing massage heads have multiple functions, such as lifting and heating. For example, Chinese utility model patent CN221655068U discloses a warm massager with an up-and-down adjustment device. By setting a movable rod perpendicular to the top surface of the shell, when the drive component drives the movable rod to move, the movable rod drives the first massage component to move vertically up and down. Compared with existing moxibustion devices that move in an arc and rise, this device has a shorter lifting stroke and a higher reciprocating lifting massage frequency, resulting in a better massage effect. Moreover, the lifting amplitude is small, and it occupies less space when used.

[0004] The following defects exist when using this type of massage head device: (1) The range of massage head lifting height is related to the length of the lead screw, and the increase of lead screw length will lead to an increase in the overall height of the massager, thereby increasing the overall volume, which is not only inconvenient to use, but also increases production costs; (2) The massage head itself cannot rotate, resulting in poor massage effect. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a novel lifting massage head structure, massage mechanism, and walking massager to solve the problems that the lifting height range of existing massage heads is related to the length of the lead screw, and that increasing the length of the lead screw will increase the overall height of the massager, thereby increasing the overall volume, which is not only inconvenient to use, but also increases production costs, and the massage head itself cannot rotate, resulting in poor massage effect.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a novel lifting massage head structure, comprising: First transmission rod; The second transmission rod is sleeved around the first transmission rod and is circumferentially linked and axially slidingly engaged with the first transmission rod. A massage head, which is fixed to one end of the second transmission rod; At least one adjusting element; when there are multiple adjusting elements, the multiple adjusting elements are nested together by threads from the inside to the outside, and the innermost adjusting element is threaded around the second transmission rod. The stop structure is provided between adjacent adjusting members and between the adjusting member and the second transmission rod, so that the second transmission rod and the adjusting member are circumferentially limited after axial movement into place; A limiting component, which is located around the outermost adjusting component and is in frictional engagement with it; When the first transmission rod rotates, the second transmission rod rotates and moves axially relative to the innermost adjusting member. After moving into position, it is circumferentially limited by the stop structure to drive the innermost adjusting member to rotate and move axially. After the adjusting member is circumferentially limited step by step, the outermost adjusting member rotates against the friction of the limiting member.

[0007] Preferably, the outer surface of the second transmission rod is provided with an external thread, and the stop structure is an abutment part provided in the internal thread groove of the adjusting member. When the second transmission rod and the adjusting member are axially moved into place and circumferentially limited, one end of the external thread abuts against the abutment part.

[0008] Preferably, the abutting part is a stop block, and the baffle is detachably fixedly installed at one end of the adjusting member. The stop block is fixed on the baffle, and when the baffle is fixed at one end of the adjusting member, the stop block is located in the threaded groove.

[0009] Preferably, the abutting part is a penetrating member, one end of which passes through the adjusting member and enters the threaded groove.

[0010] A massage mechanism includes the novel lifting massage head structure and a housing. A rotary drive motor is installed inside the housing, and a transmission wheel is rotatably installed inside the housing. The rotary drive motor is connected to the transmission wheel, and the transmission wheel is fixedly connected to a first transmission rod.

[0011] Preferably, a heating element is provided at the middle position of the top surface of the housing.

[0012] A walking massager includes the massage mechanism, a support member, and at least one rack and pinion guide rail, the rack and pinion guide rail being fixed to the support member, and the housing being slidably connected to the rack and pinion guide rail.

[0013] Preferably, it further includes at least one guide member, which is fixed to the support member, and both the guide member and the rack guide rail have protective members at one end.

[0014] Preferably, the protective component is a rubber block, and the top surface of the rubber block is arc-shaped at the end furthest from its connection with the guide component and the rack and pinion guide rail.

[0015] Preferably, it also includes an outer sleeve and a support frame, the support member is surrounded by a support frame, the outer sleeve is wrapped around the support frame, and the outer sleeve has several through holes facing the heating element.

[0016] Compared with the prior art, the beneficial effects that this invention can achieve are: This invention utilizes a multi-stage, nested, threaded adjusting mechanism and a second transmission rod structure to achieve superimposed lifting strokes of the massage head through multi-stage adjustment. Under the same lifting height requirement, it can effectively shorten the axial dimension when using a single lead screw. The multi-stage adjusting mechanism can be nested and stored together when not in operation, significantly reducing the overall size and space occupied by the device, making it easy to use, while also reducing material and processing costs.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention is further described below in conjunction with specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this invention.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10 As shown, the present invention provides a novel lifting massage head structure, including a first transmission rod 2, a second transmission rod 3, a massage head 11, at least one adjusting component, a stop structure 4, and a limiting component 7; The second transmission rod 3 is sleeved around the first transmission rod 2, and is circumferentially linked and axially slidingly engaged with the first transmission rod 2. That is, the second transmission rod 3 can move axially along the outer surface of the first transmission rod 2, and when the first transmission rod 2 rotates, it will drive the second transmission rod 3 to rotate synchronously. The massage head 11 is fixed to one end of the second transmission rod 3. When the second transmission rod 3 rotates, it can drive the massage head 11 to rotate. When there are multiple adjusting components, the multiple adjusting components are nested with each other in a threaded manner from the inside to the outside, and the innermost adjusting component is threaded around the second transmission rod 3. A stop structure 4 is provided between adjacent adjusting parts and between the adjusting parts and the second transmission rod 3 to limit the second transmission rod 3 and the adjusting parts circumferentially after they are axially moved into place. The stop structure 4 here ensures that when the second transmission rod 3 and the adjusting parts rotate and move along the second transmission rod 3 axially to a certain distance and are circumferentially limited, the second transmission rod 3 drives the adjusting parts sleeved outside it / the adjusting parts drive another adjusting part sleeved outside it to rotate together. The limiting member 7 is located around the outermost adjusting member and is in frictional engagement with it (when the inner adjusting member rotates, the limiting member 7 presses against the outermost adjusting member to ensure the normal rotation and axial displacement of the inner adjusting member; when all the inner adjusting members are displaced to the circumferential limit, the driving force of the first transmission rod 2, due to the stop structure 4, overcomes the friction of the limiting member 7 against the outermost adjusting member, thereby driving the outermost adjusting member to rotate). The limiting component 7 is a rubber anti-slip block / ring fixed on the housing 1. The outermost adjusting component and the rubber anti-slip block / ring achieve frictional limiting cooperation through end face friction / circumferential friction. The outermost adjusting component can rotate relative to the rubber anti-slip block after overcoming the frictional force of the rubber anti-slip block. Since the innermost adjusting component, the second transmission rod 3, and multiple adjusting components are all nested together by threads, when the first transmission rod 2 rotates, it will drive the second transmission rod 3 to rotate. The second transmission rod 3 rotates and moves axially relative to the first transmission rod 2. After moving into position, it is circumferentially limited by the stop structure 4, which drives the innermost adjusting component to rotate and move axially relative to the adjusting component on its outer side. After being limited step by step, the outermost adjusting component only rotates against the frictional force of the limiting component 7 and does not produce axial movement. This realizes the lifting and rotating massage of the massage head 11, resulting in a better massage effect. By setting up a multi-level nested adjusting component and the second transmission rod 3 structure, the lifting stroke of the massage head 11 is superimposed through multi-level adjustment. Under the same lifting height requirement, the axial dimension when using a single lead screw can be effectively shortened. The multi-level adjusting components can be nested together when not in operation, which greatly reduces the overall size and space occupied by the equipment, making it easy to use, while reducing material and processing costs.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 10 As shown, there are two adjusting parts here, including an internal threaded sleeve 5 and an external threaded sleeve 6. The internal threaded sleeve 5 is threadedly engaged with the second transmission rod 3, the external threaded sleeve 6 is threadedly engaged with the internal threaded sleeve 5, and the external threaded sleeve 6 is frictionally engaged with the limiting part 7. When the first transmission rod 2 rotates in the forward direction, it drives the second transmission rod 3 to rotate in the forward direction. Because the internal threaded sleeve 5 is threadedly engaged with the second transmission rod 3, the second transmission rod 3 rotates while simultaneously moving upwards along the axial direction of the first transmission rod 2. When the second transmission rod 3 reaches its axial position and is circumferentially limited, but the position of the internal threaded sleeve 5 remains unchanged (e.g....), Figure 4As shown), under the action of the stop structure 4, it circumferentially abuts against the inner threaded sleeve 5, so that when the second transmission rod 3 continues to rotate, the inner threaded sleeve 5 will also rotate. Since the outer threaded sleeve 6 is threadedly engaged with the inner threaded sleeve 5, the inner threaded sleeve 5 rotates and moves upward along the axial direction of the first transmission rod 2. When the inner threaded sleeve 5 rises (i.e., the massage head 11) to the highest point (as shown), Figure 1 and Figure 2 As shown), under the action of the stop structure 4, it abuts against the external threaded sleeve 6 in a circumferential limiting manner, thereby driving the external threaded sleeve 6 to overcome the frictional force of the limiting part 7, so that the external threaded sleeve 6 also rotates synchronously, thereby ensuring that the massage head 11 rotates for massage. At this time, the massage head 11 rises the highest distance. When the first transmission rod 2 rotates in the reverse direction, it drives the second transmission rod 3 to rotate in the reverse direction. Since the internal threaded sleeve 5 is threadedly engaged with the second transmission rod 3, the second transmission rod 3 rotates while simultaneously moving downwards along the axial direction of the first transmission rod 2. When the second transmission rod 3 reaches its lowest point, it is circumferentially stopped and abutted against the internal threaded sleeve 5 by the stop structure 4. Therefore, as the second transmission rod 3 continues to rotate, the internal threaded sleeve 5 also rotates. Since the external threaded sleeve 6 is threadedly engaged with the internal threaded sleeve 5, the internal threaded sleeve 5 rotates while simultaneously moving downwards along the axial direction of the first transmission rod 2. When the internal threaded sleeve 5 reaches its highest point, it is circumferentially stopped and abutted against the external threaded sleeve 6 by the stop structure 4. This causes the external threaded sleeve 6 to overcome the frictional force of the limiting part 7, causing it to rotate synchronously, thus ensuring the massage head 11 rotates for massage. At this time, the massage head 11 reaches its lowest point (e.g., Figure 3 (as shown) By setting up a multi-level, mutually nested adjusting component and a second transmission rod 3 structure, the multi-level adjustment achieves the superposition of the lifting stroke of the massage head 11. Under the same lifting height requirement, the axial dimension when using a single lead screw can be effectively shortened. The multi-level adjusting components can be nested together when not in operation, which greatly reduces the overall size and space occupied by the equipment, making it easy to use and reducing material and processing costs. At the same time, the massage head 11 can rotate and massage while lifting, resulting in a better massage effect.

[0021] The number of adjustment components can be as follows: Figure 9 One shown Figure 8 The three or more shown above operate on similar principles and will not be elaborated upon here.

[0022] like Figure 6 and Figure 7As shown, the stop structure 4 is an abutment part set in the internal thread groove of the adjusting member. The outer surface of the second transmission rod 3 is provided with external thread (the external thread can be set on part of the outer surface; when the entire outer surface is provided with external thread, the length of the adjusting member will be increased accordingly). When the second transmission rod 3 and the adjusting member are axially moved into place and circumferentially limited, one end of the external thread abuts with the abutment part. The abutment part can be one of two types or a combination of both. The abutment part is a stop block. One end of the adjusting part is open and can be detachably and fixedly installed with a baffle 41. The stop block is fixed on the baffle 41. When the baffle 41 is fixed to one end of the adjusting part, the stop block is located in the threaded groove. By using the stop block set in this way as the abutment part, it is possible to avoid using a penetrating part through the adjusting part, thereby ensuring the integrity of the adjusting part product. The abutting part is a penetrating part, with one end of the penetrating part passing through the adjusting part and entering the threaded groove. The abutting part can be a pin or a screw, with one end of the pin or screw passing through the adjusting part and entering the threaded groove. Setting a pin or screw as the abutting part will damage the overall appearance of the adjusting part, but it can avoid the trouble of assembling the baffle 41.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 13 As shown, a massage mechanism includes a novel lifting massage head structure and a housing 1. The outermost adjusting component is rotatably limited within the housing 1. The housing 1 contains a rotary drive motor 9 and a first reduction gear set 10. A transmission wheel 8 is rotatably mounted within the housing 1. The rotary drive motor 9 is connected to the transmission wheel 8 via the first reduction gear set 10 (the specific transmission principle is existing technology and will not be described in detail here). The transmission wheel 8 is fixedly connected to the first transmission rod 2. A heating element 12 is provided at the center of the top surface of the casing 1; By placing the heating element 12 in the center of the top surface of the housing 1, compared to the traditional solution that requires integrating the heating element 12, wiring, and heat insulation structure inside the massage head 11, resulting in a crowded internal space, complex structure, and cumbersome assembly process, this solution removes the heating element 12 from the massage head 11. This significantly simplifies the internal design of the massage head 11, reduces the number of parts inside the massage head 11, lowers assembly complexity and labor costs, and improves the structural reliability of the massage head 11. Since the heating element 12 is fixed to the top surface of the housing 1, it does not need to reciprocate or rotate with the massage head 11, avoiding the reciprocating / rotational movement of the heating wires that occurs in traditional solutions. This design avoids reliability issues such as wire breakage and poor contact caused by repeated bending. Furthermore, the wiring of the heating element 12 can be directly routed inside the housing 1 without passing through the moving joints of the massage head 11, simplifying the overall wiring design, reducing the risk of electrical failures, and improving the product's lifespan and safety. The heating element 12 is integrated into the housing 1, providing a fixed installation structure. During later maintenance and replacement, there is no need to disassemble the massage head 11 assembly; simply opening the housing 1 is sufficient, significantly reducing the difficulty and cost of after-sales maintenance. In contrast, replacing the heating element 12 inside the traditional massage head 11 requires disassembling the massage head 11, rewiring, and resealing, resulting in high maintenance costs and long cycles.

[0024] like Figures 1-5 As shown, the lifting massage head structure is set in two sets, symmetrically arranged on both sides of the housing 1. The first transmission rod 2 of the two sets of lifting massage head structures is synchronously connected to the first reduction gear set 10 and the transmission wheel 8 through the transmission transmission. The first reduction gear set 10 is driven to rotate by the forward or reverse rotation drive motor 9, thereby driving the transmission wheel 8 to rotate in the forward or reverse direction. The transmission wheel 8 drives the first transmission rod 2 to rotate in the forward or reverse direction.

[0025] like Figure 12 and Figure 13 As shown, the top surface of the housing 1 is provided with a cover plate 13, which covers the heating element 12. By setting the cover plate 13, the heating element 12 can be protected on the one hand, and heat can also be concentrated in the middle position on the other hand.

[0026] The cover plate 13 is made of transparent material. The infrared rays / heat energy emitted by the heating element 12 can directly penetrate the transparent material and act on the human body. Unlike the opaque cover plate 13, it will not absorb or block heat, which greatly improves the efficiency of thermotherapy. The transparent cover plate 13 covers the spinal area. With the through hole 191 of the outer cover 19, the heat energy can reach the spine directly through the through hole 191 with low loss, achieving precise coverage of "heating in the middle and massaging on both sides". Users can intuitively see the heating area and working status of the heating element 12 (such as turning red when heated, temperature distribution) through the transparent cover 13, enhancing the product's technological feel and interactive experience. If the heating element 12 partially fails to light up or heat, users can quickly identify the fault through the transparent cover 13 for timely repair. The transparent cover 13 can "protect" the internal heating element 12 while still making it "visible," creating a high-end and intelligent visual effect in conjunction with the LED indicator.

[0027] like Figure 5 , Figure 12 and Figure 14 As shown, a walking massager includes a massage mechanism, a support member 16, and at least one rack and pinion guide rail 15. The rack and pinion guide rail 15 is fixed to the support member 16. The housing 1 is slidably connected to the rack and pinion guide rail 15. Specifically, a walking drive motor 14 is installed inside the housing 1. The walking drive motor 14 is connected to the rack and pinion guide rail 15 through a second reduction gear set 21 (the specific transmission principle is existing technology and will not be described in detail here). When this massage mechanism is applied to a walking massager, its heating element 12 is located in the middle of the top surface of the housing 1, which can directly correspond to the physiological direction of the human spine, so as to achieve continuous, stable and full-coverage heating of the spine and surrounding core areas such as the Du meridian and Jiaji acupoints, thus meeting the needs of spinal heating care. Similarly, when applied to a neck and shoulder massager, it can heat the cervical spine to meet the need for neck heating and care.

[0028] like Figure 12 and Figure 14 As shown, it also includes at least one guide member 18, which is fixed to the support member 16. Both the guide member 18 and the rack and pinion guide rail 15 are provided with a protective member 17 at one end. The protective member 17 is an independent modular component that can be fixed to the end of the guide member 18 and the rack and pinion guide rail 15 by quick snap-fit / screw connection or other fixing methods. The assembly process is simple and does not require complicated debugging, which greatly improves the assembly efficiency of the production line. At the same time, the protective member 17 can be replaced separately if it is damaged, without disassembling the entire guide rail assembly, which reduces after-sales maintenance costs. Here, a guide 18 and a rack guide 15 are set up to cooperate. On the one hand, this reduces the number of second reduction gear sets 21 and reduces production and assembly costs. On the other hand, since there is contact wear on the tooth surfaces of the two rack guides 15 and the two traveling gears, the cumulative wear after long-term operation will lead to a decrease in transmission accuracy. The single rack guide 15 and the traveling gear have single-sided contact transmission, the wear point is single, the wear rate is slower, and there is no risk of gear meshing loosening or tooth dislodging. This extends the service life of the movement transmission structure and reduces the failure rate in the later stage. By setting up the protective element 17, it is possible to prevent the sharp points of the guide element 18 and the rack and pinion rail 15 from piercing a person's back when the walking massager is used as a lumbar support.

[0029] The protective component 17 is a rubber block, and the top surface of the rubber block is curved at the farthest point from its connection with the guide component 18 and the rack and pinion guide rail 15. The guide component 18 and the rack and pinion rail 15 are at the extreme positions of the movement. Long-term impact from the movement can easily cause deformation, tooth damage, and wear. The rubber protective component 17 can serve as an end buffer structure to absorb the impact at the end of the movement, reduce the force and wear on the ends of the guide component 18 and the rack and pinion rail 15, prevent guide rail deformation and tooth breakage, extend the service life of the guide component 18 and the rack and pinion rail 15 and the movement, and improve the long-term reliability of the product. The rubber material has excellent elasticity and cushioning performance. Even if the back accidentally hits the end of the guide 18 and the rack and pinion rail 15, the rubber block can effectively absorb the impact energy, avoiding the bumps, pain and damage caused to the human body by the hard guide 18 and the rack and pinion rail 15. The rubber material has excellent sound insulation and shock absorption performance, which can effectively absorb the impact noise of the movement to the end, making the massage process quieter and improving the user experience. The top surface of the protective component 17, away from the connecting end, is designed with an arc shape, which can perfectly adapt to the physiological curve of the human back and avoid the "hard edge" and foreign object feeling brought by the flat protective component 17. When the user leans against it, the back and the protective component 17 transition smoothly and fit completely, without local pressure or back discomfort, greatly improving the comfort of use. The arc structure can evenly distribute the pressure of the human body leaning against it, avoiding the edge of the flat protective component 17 from causing local concentrated pressure marks on the back. Even after long-term use, there will be no pain or discomfort, making it suitable for use scenarios such as sitting for a long time and long-term massage.

[0030] like Figure 11 , Figure 12 and Figure 13 As shown, it also includes an outer sleeve 19 and a support frame 20. The support frame 20 is fitted around the support member 16. The support frame 20 has a certain depth and its height is not higher than the height of the massage head 11 when it is at its lowest position. The outer sleeve 19 is wrapped around the support frame 20. Several through holes 191 are opened on the outer sleeve 19 facing the heating element 12. The support frame 20 can be made of foam sponge. The main reason for using sponge is that it has a better feel. In addition to conventional sponge, memory foam can also be used. Alternatively, materials with strong support and good strength, such as plastic or metal, can be used as substitutes. By setting up a support frame 20 to wrap around the support member 16, and at the same time, when a person uses the walking massager for lumbar support, the sharp points of the guide member 18 and the rack and pinion rail 15 will further prevent people from stabbing their backs when they lean on it. The outer casing 19, with its design, prevents foreign objects such as dust, hair, dander, and liquids from entering the internal mechanism and the transmission area of ​​the rack and pinion guide 15. This avoids jamming of the mechanism and transmission failure caused by foreign objects, significantly reducing the failure rate and extending the product's lifespan. As the outermost wear-resistant layer, the outer casing 19 can withstand the friction and scratches of daily use, preventing direct wear and aging of the support frame 20 and the casing 1. It also isolates the internal rack and pinion guide 15 and mechanism from the corrosion of sweat and moisture, improving the overall durability of the machine. By setting the through hole 191, heat can be transferred to the human spine area without obstruction when the heating element 12 is working. This avoids the decrease in thermal efficiency and local overheating caused by the outer casing 19 blocking the heat, achieving the core requirement of precise spinal thermotherapy. The elongated shape of the through hole 191 perfectly matches the direction of the spine, ensuring that the heat zone covers the core physiotherapy areas such as the Du meridian and Jiaji acupoints, improving the targeting and effect of thermotherapy, while also improving breathability and sweat-wicking performance, avoiding the stuffiness of prolonged use.
