Description

Technical Field

[0001] The utility model relates to personal care equipment, in particular to massage equipment. Background Art

[0002] The sole of the foot is a microcosm of the human body. The arrangement of all organs and glands in our body is the same as that of the reflex zone of the sole of the foot. An experienced foot massage worker can easily find the location of these crystals and massage them away to achieve therapeutic effects. In today's society, people are generally busy and it is difficult to have time to go to a professional masseur for massage, so various types of foot massage equipment have been extended, including various foot baths, massage mats and massage beds. At present, common foot massage devices generally use fixed position rotation, sliding wheels and infrared rays to produce foot massage techniques such as rubbing, scraping and vibration.

[0003] However, to produce these different massage techniques, a relatively complex drive structure is often required, such as using multiple motors and multiple drive shafts to drive different transmission parts to drive the massage parts to move to simulate different massage techniques. This makes the whole machine structure complex, easy to damage, and the cost is relatively high. Utility Model Content

[0048] refer to Figure 1-Figure 8 This embodiment provides a massager that can be used to massage the calf and foot. The massager includes a base 1 and a massage core placed on the base 1. Three groups of baffle walls 11 are arranged on the base 1 along the width direction, so that left and right accommodating spaces are formed between two adjacent groups of baffle walls 11. The massage parts of the massage core are arranged corresponding to the above-mentioned accommodating spaces, so as to massage the treated part (such as the calf and foot) of the user placed in the accommodating space.

[0049] The massager in this embodiment includes a calf massage movement 2 for kneading, single rolling and scraping the legs, and a foot massage movement 3 for massaging the feet. The calf massage movement 2 in this embodiment uses only one driving member 21 and one rotating shaft 22 to simultaneously achieve three different massage actions including kneading, single rolling and scraping for the calves on both sides, which greatly simplifies the structure of the calf massage movement 2. The foot massage movement 3 can refer to the calf massage movement 2 and be set to the same structure as it, or it can be a different structure from the calf massage movement 2. The designer can choose by himself, and the detailed description is omitted here.

[0050] like Figure 1 As shown, the calf massage movement 2 is configured to be mainly used for massaging the calf of the person being treated. The foot massage movement 3 is configured to be mainly used for massaging the foot of the person being treated. The calf massage movement 2 is located on the upper side of the foot massage movement 3.

[0051] like Figure 1 and Figure 4As shown, the calf massage mechanism 2 has a driving member 21, a rotating shaft 22, a left massage part corresponding to the left calf and a right massage part corresponding to the right calf. The driving member 21 is located in the center of the rotating shaft 22, and the left massage part and the right massage part are respectively placed on the left and right sides of the driving member. That is, the left massage part, the driving member and the right massage part are sequentially arranged on the rotating shaft 22. Figure 1 As shown, the left massage part is correspondingly arranged in the left calf accommodating space, and the right massage part is correspondingly arranged in the right calf accommodating space.

[0052] like Figure 4 , Figure 5 As shown, in this embodiment, the left massage part has a first massage part 25, a second massage part 26 and a third massage part 27, and the right massage part also has a first massage part 25, a second massage part 26 and a third massage part 27. The left massage part and the right massage part are symmetrically arranged across the driving part 1, are driven by the same rotary shaft 22, and have the same structure. Below, the structure of the left massage part is taken as an example to explain the parts with the same structure in the massage parts on both sides.

[0053] The first massage member 25 is disposed near the driving member 21 and is connected to the rotating shaft 22 via the first transmission member 23. In this embodiment, the first massage member 25 massages the inner side of the calf (i.e., the side of the calf between the left and right calves) for treatment. The second massage member 26 is connected to the rotating shaft 22 via the second transmission member 24, and the third massage member 27 is also connected to the same rotating shaft 22. In this embodiment, the second massage member 26 and the third massage member 27 are respectively located on the inner side of the left and right massage parts, corresponding to massaging the back side of the calf.

[0054] As described above, the rotary shaft 22 passes through the left massage part and the right massage part, and when driven by the driving member 21 to rotate, it can simultaneously drive the first massage member 25, the second massage member 26 and the third massage member 27 of the left massage part and the right massage part.

[0055] Next, the driving mechanism of the calf massage movement 2 will be described.

[0056] like Figure 5As shown, the driving mechanism used in the calf massage movement 2 specifically includes: a driving member 21, a rotating shaft 22, a first transmission member 23 and a second transmission member 24. The driving member 21 can be a driving motor. The driving member 21 is connected to the rotating shaft 22 through a reversing mechanism (not shown). The reversing mechanism plays a role in converting the output of the driving member 21 into the rotation of the rotating shaft 22, so that the output rotating shaft of the driving member 21 can be placed vertically with the rotating shaft 22 to save space. As a result, the driving member 21 and the rotating shaft 22 are reversed to drive the rotating shaft 22 to rotate around its own axis. In this embodiment, the driving member 21 is located between the left massage part and the right massage part, and does not occupy the calf accommodation space on the left and right sides. The extension direction of the driving member 21 is orthogonal to the extension direction of the rotating shaft 22, and extends toward the reciprocating direction of the second massage member 26 described later, which can effectively utilize the space between the left massage part and the right massage part to prevent the space from being too large, which is conducive to the miniaturization of the device.

[0057] like Figure 5 and Figure 6 As shown, the first transmission member and the second transmission member are respectively arranged on the left and right sides of the massager. In this embodiment, with the driving member located in the center of the rotary shaft 22 as the center, the first transmission member and the second transmission member on the left side are symmetrically arranged with the first transmission member and the second transmission member on the right side, and the first transmission member is closer to the center than the second transmission member.

[0058] like Figure 6 and Figure 7 As shown, the first transmission member 23 includes a first eccentric wheel 231 eccentrically connected to the rotating shaft 22 and an extension 232 connected to the first eccentric wheel 231. The rotating shaft 22 can drive the first transmission member 23 to swing eccentrically relative to the rotating shaft 22 via the first eccentric wheel 231. In this embodiment, one end 232A of the extension 232 is sleeved on the first eccentric wheel 231, and moves in the front-to-back direction as the first eccentric wheel rotates. The front-to-back direction is the front-to-back direction of the human body when the calf is treated, that is, the front-to-back direction of the calf massager.

[0059] like Figure 3As shown, the extension portion 232 extends outwardly along the radial direction of the first eccentric wheel 231. A first guide groove 2321 is provided in the extension portion 232 of the first transmission member 23. In this embodiment, the first guide groove 2321 is provided at the other end 232B of the extension portion 232 opposite to the end connected to the first eccentric wheel 231. A first limiting member 233 is fixedly provided at a position corresponding to the base 1 and the extension portion 232. The first limiting member 233 is slidably connected to the first guide groove 2321. In this embodiment, the first limiting member 233 is a limiting rod, which is inserted through the first guide groove 2321. When the rotating shaft 22 drives the first eccentric wheel 231 to rotate eccentrically, the limiting rod inserted through the first guide groove 2321 can prevent the extension portion 232 from rotating with the rotating shaft 22. Through the linkage of the first eccentric wheel 231 and the first stopper 233, when the rotary shaft 22 drives the first eccentric wheel 231 to rotate eccentrically, the extension part 232 can reciprocate along the extension direction of the first guide groove 2321. In this embodiment, the extension direction of the first guide groove 2321 is along the extension direction of the calf when the calf is treated, that is, close to the up and down direction of the calf massager. Specifically, the reciprocating motion is manifested as: when the extension part 232 reciprocates under the limiting action of the first guide groove 2321 and the first stopper 233, the angle formed by the extension part 232 and the base 1 when moving in the first direction (for example, toward the top of the calf massager) is different from the angle formed by the extension part 232 and the base 1 when moving in the second direction opposite to the first direction (for example, toward the bottom of the calf massager). In this embodiment, the angle formed between the extension portion 232 and the base 1 when the extension portion 232 moves upward is smaller than the angle formed between the extension portion 232 and the base 1 when the extension portion 232 moves downward.

[0060] As described above, when the rotary shaft 22 rotates and the extension 232 moves with the eccentric rotation of the first eccentric wheel 231, the extension 232 is driven by the rotary shaft 22 and eccentrically swings relative to the rotary shaft 22. That is, the extension 232 has both the front-to-back movement of the calf massager and the up-and-down movement of the calf massager. The movement amount of one end 232A of the extension 232 connected to the first eccentric wheel 231 in the front-to-back direction is greater than the movement amount of the other end 232B of the extension 232 opposite to the one end 232A connected to the first eccentric wheel 231 in the front-to-back direction.

[0061] like Figure 6 and Figure 7As shown, the second transmission member 24 includes a second eccentric wheel 241 eccentrically connected to the rotary shaft 22 and a connecting rod portion 242 connected to the second eccentric wheel 241. The rotary shaft 22 can drive the connecting rod portion 242 of the second transmission member 24 to reciprocate via the second eccentric wheel 241. In this embodiment, one end 242A of the connecting rod portion 242 connected to the second eccentric wheel 241 is sleeved on the outer side of the second eccentric wheel 241, and moves in the front-to-back direction with the rotation of the second eccentric wheel 241, that is, it has a movement amount in the front-to-back direction close to the calf massager.

[0062] like Figure 7 As shown, the connecting rod portion 242 extends outwardly along the radial direction of the second eccentric wheel 241. A second guide groove 2421 is provided on the connecting rod portion 242 of the second transmission member 24. In this embodiment, the second guide groove 2421 is provided at the other end 242B of the connecting rod portion 242 opposite to the end connected to the second eccentric wheel 241. A second stopper 243 is fixedly provided at a position corresponding to the base 1 and the connecting rod portion 242. The second stopper 243 is slidably connected to the second guide groove 2421. The second stopper 243 is a stopper rod, which is inserted through the second guide groove 2421. Similar to the first transmission member 23, through the linkage between the second eccentric wheel 241 and the second stopper 243, when the rotary shaft 22 drives the second eccentric wheel 242 to make an eccentric motion, the connecting rod portion 242 also reciprocates along the extension direction of the second guide groove 2421. In this embodiment, the other end 242B of the connecting rod 242 opposite to the second eccentric wheel 241 has a movement amount in the up-and-down direction of the calf massager. Specifically, the reciprocating motion is manifested as follows: when the connecting rod 242 reciprocates under the limiting action of the second guide groove 2421 and the second limiting member 243, the angle formed by the connecting rod 242 and the base 1 when it moves in the first direction (for example, toward the top of the calf massager) is different from the angle formed by the connecting rod 242 and the base 1 when it moves in the second direction opposite to the first direction (for example, toward the bottom of the calf massager). In this embodiment, the angle formed by the connecting rod 242 and the base 1 when it moves upward is smaller than the angle formed by the connecting rod 242 and the base 1 when it moves downward.

[0063] As described above, when the connecting rod 242 moves with the rotation of the second eccentric wheel, it swings eccentrically relative to the rotary shaft 22. That is, the connecting rod 242 has both the front-to-back movement of the calf massager and the up-down movement of the calf massager, and the movement amount of one end 242A of the connecting rod 242 connected to the second eccentric wheel 241 in the front-to-back direction is greater than the movement amount of the other end 242B of the connecting rod 242 opposite to the one end connected to the second eccentric wheel 241 in the front-to-back direction.

[0064] As described above, since all transmission members are disposed on the same rotary shaft 22 , when the rotary shaft 22 rotates around its own axis under the action of the driving member 21 , it can simultaneously drive the first transmission member 23 and the second transmission member 24 to move.

[0065] Next, the relationship between the driving mechanism and each massage element will be described.

[0066] As described above, one end 232A of the extension 232 of the first transmission member 23 is connected to the rotary shaft 22 via the first eccentric wheel 231, and the other end 232B is freely slidably sleeved on the base 1 via the first stopper 233. Therefore, when the extension 232 moves with the rotation of the first eccentric wheel 231, the extension 232 swings eccentrically relative to the rotary shaft 22.

[0067] like Figures 3 to 7 As shown, the first massage member 25 is disposed on the extension 232 of the first transmission member 23. In this embodiment, the first massage member 25 has two connecting parts 251 and 252 relatively fixedly connected to the extension 232. The connecting part 251 is fixed to one end 232A connected to the first eccentric wheel 231 near the extension 232. The connecting part 252 is fixed to the other end 232B opposite to the one end 232A connected to the first eccentric wheel 231 near the extension 232. In this embodiment, the connecting part 252 is close to the first guide groove 2321. The first massage member 25 can be connected to the one end 232A side and the other end 232B side of the extension 232 at the same time through the connecting parts 251 and 252. Therefore, when the first massage member 25 moves with the eccentric rotation of the first eccentric wheel 231, the first massage member 25 also performs eccentric swinging through the transmission of the extension 232. That is, the first massage member 25 moves in the front-to-back direction while also moving in the up-to-down direction of the massager, but the portion of the first massage member 25 close to the first eccentric wheel 231 is displaced more in the front-to-back direction of the massager than the portion close to the first guide groove 2321. If a certain imaginary point of the first massage member 25 is focused on, its motion trajectory is roughly elliptical. As a result, it is easier to achieve kneading massage of the treated part, such as the inner side of the calf.

[0068] In this embodiment, the first massage member 25 is an airbag, which is arranged on the inner side of the calf of the massage part. When the airbag is inflated, the first massage member 25 can squeeze the inner side of the calf and knead the inner side of the calf in the front-back and up-down directions at the same time through the drive of the first eccentric wheel 231. Thus, the first transmission member 23 drives the airbag as the first massage member 25, and by combining the inflation and deflation of the airbag, it can provide more different body-feeling kneading massages to the inner side of the calf as the treated part.

[0069] In this embodiment, there are two connection parts 251 and 252, and the two connection parts 252 are spaced apart and close to the first eccentric wheel 231 and the first guide groove 2321. However, it is not limited thereto, and the connection part may be formed as one body, or may have a plurality of connection parts.

[0070] In this embodiment, the first massage element 25 is an air bag capable of being inflated and deflated, but it may also be other means capable of achieving a similar squeezing effect, such as an elastic object with a certain strength.

[0071] The left massage part and the left and right massage parts respectively have the above-mentioned first massage parts 25. The first massage parts 25 on the left and right sides are respectively linked to the same rotating shaft 22 via the first transmission parts 23 on the left and right sides. In this way, the linkage of the first massage parts 25 on the left and right sides can be achieved, and the synchronization of the two can also be adjusted. However, it is not limited to this. In order to ensure the consistency of the movements of the two first massage parts 25 respectively placed in the left and right calf accommodating spaces, a connecting member 253 can also be provided. The two first massage parts 25 on the left and right sides are connected by the connecting member 253.

[0072] like Figure 3 and Figure 4 As shown, in this embodiment, the connecting member 253 spans between the extensions 232 on the left and right sides, and is fixed to the extensions 232 on the left and right sides along the extension direction of the extensions 232. The extensions 232 are formed to extend from the first eccentric portion 231 along the up-down direction. The first massage members 25 on the left and right sides are respectively fixed to the same connecting member 253. Thus, the first massage members 25 on the left and right sides are respectively fixed to the extensions 232 on the left and right sides via the same connecting member 253. Through the above structure, the massage synchronization of the first massage members 25 on the left and right sides can be further achieved.

[0073] As described above, one end 242A of the connecting rod portion 242 of the second transmission member 24 is connected to the rotary shaft 22 via the second eccentric wheel 241, and the other end 242B is freely slidably mounted on the base 1 via the second stopper 243. Thus, when the connecting rod portion 242 moves with the rotation of the second eccentric wheel 241, the connecting rod portion 242 performs eccentric swing relative to the rotary shaft 22. The other end 242B of the second massage member 26 away from the second eccentric wheel 241 mainly performs reciprocating motion.

[0074] like Figures 5 to 7As shown, the second massage member 26 is disposed at the other end 242B of the connecting rod 242 opposite to the end connected to the second eccentric wheel 241. The second massage member 26 is linked with the second transmission member 24, and reciprocates in the length direction of the connecting rod 242 (i.e., the extension direction of the calf as the treated part). The reciprocating direction of the second massage member 26 is preferably a reciprocating motion along the same plane. Thus, when the second massage member 26 disposed at the rear side of the massage space reciprocates along the up-and-down direction of the calf massager, the second massage member 26 can perform scraping massage on the rear side of the calf.

[0075] A first massage protrusion 261 may also be provided on the second massage member 26. In this embodiment, the first massage protrusion 261 extends in a direction parallel to the rotation axis 22, forming a transverse protrusion, and the height of the central portion is lower than the height of the left and right ends. In this embodiment, two first massage protrusions 261 are provided at intervals on the upper surface of the second massage member 26 in a direction parallel to the rotation axis 22. The two first massage protrusions 261 are configured such that the protrusion height gradually increases from the side facing each other to the side facing away from each other. In this way, the two first massage protrusions 261 form a space with a concave central portion, which is convenient for the user to place the calf, and is also conducive to the fit of the two first massage protrusions 261 of the second massage member with the calf, thereby increasing the scraping effect. The first massage protrusion 261 may be formed in one piece, or may be formed by two left and right protrusions together, forming a first massage protrusion 261 with a central portion height lower than the height of the left and right ends.

[0076] In this embodiment, the second massage element 26 and the connecting rod portion 242 are formed integrally, but may also be formed separately.

[0077] In this embodiment, a third massage member 27 is further provided on both sides of the second eccentric wheel 241. The third massage member 27 is provided on the rotating shaft 22 and rotates with the rotation of the rotating shaft 22. The third massage member 27 is a roller treatment part. The roller treatment part is provided with a plurality of second massage protrusions 271 at intervals along the circumference. The roller treatment part is driven to rotate by the rotating shaft 22, so that the second massage protrusions 271 massage the calf.

[0078] For the calf, the thickness of the calf gradually increases from bottom to top and then gradually decreases. The third massage part 27 is arranged above the second massage part 26, so the first massage protrusion 261 and the second massage protrusion 271 will correspond to the calf parts with different thicknesses respectively. At this time, if the height of the second massage protrusion 271 is the same as that of the first massage protrusion 261, one side will fit the massage part, while the other side cannot fit or over-fits, resulting in interference. Therefore, it is preferred that one of the first massage protrusion 261 and the second massage protrusion 271 protrudes further toward the front of the massager than the other. It is more preferred that the second massage protrusion protrudes further toward the front of the massager than the central concave portion of the first massage protrusion.

[0079] A point-pressing protrusion 29 may also be provided at one end 242A of the connecting rod 242 connected to the second eccentric wheel 241. As described above, the point-pressing protrusion 29 moves in the front-rear direction of the massager as the second eccentric wheel 241 rotates eccentrically, thereby achieving point-pressing massage of the calf as the treated part.

[0080] By providing a pressing protrusion 29 at one end 242A of the connecting rod 242 and a second massage part 26 at the other end, it is possible to perform a pressing massage while performing a scraping massage on the calf, thereby simultaneously achieving different massage methods on different parts of the lower leg.

[0081] In the above embodiment, the third massage members 27 are respectively arranged on both sides of the second eccentric wheel 241. However, the third massage member 27 may also be arranged only on either side of the second eccentric wheel 241.

[0082] In the above embodiment, the second eccentric wheel 241 and the roller constituting the third massage member 27 are formed separately, are respectively disposed on the rotary shaft 22, and are driven by the rotary shaft 22. Figure 7 and Figure 8 As shown in FIG. 1 , the second eccentric wheel 241 is formed by an eccentric protrusion extending from the third massage member 27 in the extending direction of the rotation axis. That is, the second eccentric wheel 241 is formed integrally with the third massage member 27. The second eccentric wheel 241 can be formed by an eccentric protrusion extending from the third massage member 27 on either side (e.g. Figure 8 As shown), it can also be formed by two eccentric protrusions extending toward each other from the third massage parts 27 (as shown Figure 7 shown).

[0083] In the above structure, the first massage member 25 is only arranged at one side of the leg accommodation space. In order to cooperate with the first massage member 25, a clamping airbag 28 as a clamping member may also be included. The clamping airbag 28 is arranged at a side of the second transmission member away from the first transmission member, so that a leg accommodation space is formed between the clamping airbag 28 and the first massage member.

[0084] The following is a brief description of the various massage modes of the calf massage movement 2:

[0085] When the rotary shaft 22 rotates, the third massage element 27 as the roller massage part directly rotates along with the rotation of the rotary shaft, and continuously provides roller massage.

[0086] The first transmission member 23 and the second transmission member 24 swing eccentrically with the rotation of the rotary shaft 22. The eccentric swing of the extension 232 of the first transmission member 23 and the connecting rod 242 of the second transmission member 24 are not synchronized. When the extension 232 of the first transmission member 23 moves toward the first direction (for example, above the calf massager), the connecting rod 242 of the second transmission member 24 moves toward the second direction opposite to the first direction (for example, below the calf massager). Thus, when the first transmission member 23 drives the first massage member 25 from the upper part of the calf as the treated part (the upper part of the calf massager) to the lower part of the calf as the treated part (the lower part of the calf massager), the second transmission member 24 can drive the second massage member 26 from the lower part of the calf to the upper part of the calf, thereby enhancing the squeezing effect while performing scraping massage on the calf. At this time, if there is a tapping protrusion 29 at the position of the second eccentric wheel, when the first transmission member 23 drives the first massage member 25 from the front of the calf (the front of the calf massager) to the back of the calf (the back of the calf massager), the second transmission member 24 can drive the tapping protrusion 29 from the back of the calf to the front of the calf, thereby increasing the tapping effect from the back of the calf while kneading and massaging the inner sides of the left and right calf, further enhancing the massage sensation of the calf. In this way, a rotating shaft can provide kneading massage, scraping massage, and tapping massage to the calf while providing roller massage to the calf.

[0087] It should be noted that this embodiment is described by massaging the calf as an example, but it can also be used to massage other parts, such as the foot. The above structure can be applied to a separate calf massager, or combined in a calf massager and a foot massager, which is a simple replacement of this embodiment.

[0088] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
