Description

Technical Field

[0001] This invention relates to the field of rheumatic joint massage technology, and more specifically to a rheumatic joint massage device. Background Technology

[0002] As people age, genetic factors and increased life stress contribute to a rise in various illnesses, with rheumatism being a common one. Rheumatism primarily affects joints, bones, muscles, blood vessels, and related tissues or connective tissues. Many rheumatic diseases share overlapping pathologies and similar symptoms. Rheumatism causes pain, often with an insidious onset and a long course. Treatment involves medication, along with hot compresses and massage to help relieve pain.

[0003] However, currently, when assisting patients with rheumatism to relieve pain, separate instruments are generally used for massage or hot compresses. When patients need hot compresses and massage, the two instruments need to be used alternately, which is very troublesome. Summary of the Invention

[0004] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by the present invention is: when assisting patients with rheumatism to relieve pain, a separate instrument is generally used for massage or hot compress. When patients need hot compress and massage, the two instruments need to be used alternately, which is very troublesome.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a rheumatic joint massage device, comprising: case; Two extrusion plates are arranged parallel to each other inside the housing to form a heating chamber with the housing. The extrusion plates are slidably fitted with the housing. One of the extrusion plates has multiple vent holes. A driving mechanism that can drive two extrusion plates to slide in opposite directions; Massage columns, a plurality of which are mounted on extrusion plates with vents, and the massage columns are located on the side away from another extrusion plate; the massage columns and the plurality of vents are staggered; the housing has a plurality of through holes for the massage columns to pass through, and the through holes mate with corresponding massage columns; and A heater that can heat the gas inside the heating chamber.

[0006] In this invention, the heater is turned on, heating the gas inside the heating chamber. Then, the drive mechanism is activated, causing two pressing plates to slide towards each other. When the two pressing plates slide close together, they move the massage column towards the housing, allowing it to slide out through the through-hole. This connects the heating chamber to the outside through the vent and through-hole. Simultaneously, the two pressing plates compress the gas inside the heating chamber, allowing the heated gas to apply heat to the joint through the vent and through-hole, promoting blood circulation. When the two pressing plates slide away from each other, the gas enters the heating chamber sequentially through the vent and through-hole, is heated by the heater, and then the pressing plates move the massage column through the through-hole to the outside of the housing, blocking the through-hole and preventing new gas from entering the heating chamber, reducing heat loss. This, combined with the massage, massages the joint, relieving pain. The repeated application of heat and massage to the joint enhances the pain relief effect.

[0007] Preferably, the drive mechanism includes a crankshaft, a first connecting rod, a second connecting rod, and a drive member; the crankshaft has two journals facing opposite directions, the crankshaft is rotatably mounted in the housing, the crankshaft is arranged parallel to the extrusion plates, and the crankshaft is located on the side of the two extrusion plates away from the massage column; one end of the first connecting rod is hinged to one of the journals, and the other end of the first connecting rod is hinged to the extrusion plate away from the massage column; one end of the second connecting rod is hinged to the other journal, and the other end of the second connecting rod is hinged to the other extrusion plate, and the extrusion plate away from the massage column has a clearance groove for the second connecting rod to pass through; the drive member can drive the crankshaft to rotate.

[0008] The drive component drives the crankshaft to rotate, and the crankshaft drives the first connecting rod and the second connecting rod through two journals. When the journal drives the first connecting rod to move upward and the second connecting rod to move downward, the distance between the two extrusion plates increases. When the journal drives the first connecting rod to move downward and the second connecting rod to move upward, the two extrusion plates come into contact with each other. This causes the two extrusion plates to move in opposite directions.

[0009] Preferably, it further includes a closing mechanism; the closing mechanism includes a spring and a closing plate; closing plates are respectively provided on both sides of the swing direction of the second connecting rod, the closing plates are slidably mounted on the extrusion plate, and one end of the closing plate abuts against the second connecting rod, and the other end of the closing plate is provided with a spring, the spring applies a spring force to the closing plate to slide towards the second connecting rod, so that the closing plate covers the clearance groove.

[0010] When the second link swings, the second spring pushes the closing plate to always abut against the second link, thereby ensuring that the clearance slots on both sides of the second link are always blocked by the closing plate, thus effectively preventing heat loss from the clearance slots.

[0011] Preferably, the extrusion plate with the clearance groove has a mounting cavity on the side near the crankshaft, the mounting cavity communicating with the heating cavity, and the heater disposed within the mounting cavity. The mounting cavity effectively ensures unobstructed contact between the two extrusion plates, allowing them to abut against each other; thereby venting gas from the heating cavity.

[0012] Preferably, the device also includes a tension band, which is mounted on the housing. A push groove is provided on the side of the housing away from the massage column, allowing the journal to move out of the housing via the push groove, thereby pushing the tension band towards the side away from the housing. The tension band is fitted onto the joint, so that the side of the housing closest to the massage column abuts against the joint, thus fixing the housing at the joint. When the crankshaft rotates, the journal moves out of the housing, pushing the tension band outwards, allowing the tension band to apply circumferential pressure to the joint, further massaging the joint and improving blood circulation.

[0013] Preferably, multiple massage blocks are installed on the inner side of the tension band. The tension band drives the massage blocks to squeeze and massage the joint, thereby improving the massage effect.

[0014] Preferably, a gasket is installed on the side of the housing near the massage column. The housing contacts the skin at the joint through the gasket, which can improve the patient's comfort.

[0015] Preferably, a rubber head is installed at the end of the massage column away from the compression plate. The rubber head contacts the joint, thereby improving patient comfort.

[0016] Compared with the prior art, the present invention has at least the following advantages: 1. The heater heats the gas inside the heating chamber, then controls the drive mechanism to operate. The drive mechanism drives two extrusion plates to slide towards each other. When the two extrusion plates slide closer together, they move the massage column towards the inside of the housing, causing the massage column to slide out through the through-hole. This connects the heating chamber to the outside through the vent and through-hole. Simultaneously, the two extrusion plates squeeze the gas inside the heating chamber, allowing the heated gas to apply heat to the joints through the vent and through-hole, promoting blood circulation. When the two extrusion plates slide away from each other, the gas enters the heating chamber through the vent and through-hole, is heated by the heater, and then the extrusion plates move the massage column through the through-hole to the outside of the housing, blocking the through-hole and preventing new gas from entering the heating chamber, reducing heat loss, and simultaneously massaging the joints to relieve joint pain. The repeated hot compresses and massages on the joints enhance the pain relief effect.

[0017] 2. Place the tightening strap on the joint so that the side of the housing closest to the massage column abuts against the joint, thereby fixing the housing at the joint; when the crankshaft rotates, the journal moves outside the housing, and the journal pushes the tightening strap outward, so that the tightening strap can apply circumferential pressure to the joint, thereby further massaging the joint and improving blood circulation.

Detailed Implementation

[0024] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] See Figures 1-4 The present invention provides an embodiment of a rheumatic joint massage device, comprising: a housing 1, a pressing plate 2, a driving mechanism 4, massage columns 5, and a heater 6. Two pressing plates 2 are arranged parallel to each other within the housing 1 to form a heating chamber 3, and the pressing plates 2 are slidably fitted with the housing 1. One of the pressing plates 2 has multiple ventilation holes 21. The driving mechanism 4 can drive the two pressing plates 2 to slide in opposite directions. Multiple massage columns 5 are installed on the pressing plate 2 with ventilation holes 21, and the massage columns 5 are located on the side away from the other pressing plate 2. The massage columns 5 are staggered from the multiple ventilation holes 21. The housing 1 has multiple through holes 11 for the massage columns 5 to pass through. Each massage column 5 corresponds to one through hole 11, and the through hole 11 is set on the stroke of the corresponding massage column 5. The through hole 11 cooperates with the corresponding massage column 5. Furthermore, a rubber head 51 is installed at the end of the massage column 5 away from the compression plate 2. The rubber head 51 contacts the joint, thereby improving the patient's comfort. The heater 6 can heat the gas in the heating chamber 3. Furthermore, a gasket 13 is installed on the side of the housing 1 near the massage column 5. The housing 1 contacts the skin at the joint through the gasket 13, which can improve the patient's comfort.

[0028] In practice, the heater 6 is turned on to heat the gas in the heating chamber 3. Then, the drive mechanism 4 is controlled to move, driving the two extrusion plates 2 to slide towards each other. When the two extrusion plates 2 slide closer to each other, they move the massage column 5 towards the housing 1, allowing it to slide out of the through hole 11. This connects the heating chamber 3 to the outside through the vent hole 21 and the through hole 11. At the same time, the two extrusion plates 2 squeeze the gas in the heating chamber 3, allowing the heated gas to apply heat to the joints through the vent hole 21 and the through hole 11, promoting blood circulation in the joints. When the two extrusion plates 2 slide away from each other, the gas enters the heating chamber 3 through the through hole 11 and the vent hole 21 in sequence, is heated by the heater 6, and then the extrusion plates 2 move the massage column 5 through the through hole 11 to the outside of the housing 1, blocking the through hole 11 and preventing new gas from entering the heating chamber 3, reducing heat loss from the heating chamber 3, and simultaneously massaging the joints to relieve joint pain. Furthermore, by repeatedly applying heat and massaging the joints, the pain relief effect can be improved.

[0029] See Figures 1-4 In other embodiments, the drive mechanism 4 includes a crankshaft 41, a first connecting rod 42, a second connecting rod 43, and a drive member 44. The crankshaft 41 has two journals 411 facing opposite directions. The crankshaft 41 is rotatably mounted in the housing 1. The crankshaft 41 is arranged parallel to the extrusion plates 2, and the crankshaft 41 is located on the side of the two extrusion plates 2 away from the massage column 5. One end of the first connecting rod 42 is hinged to one of the journals 411, and the other end of the first connecting rod 42 is hinged to the extrusion plate 2 away from the massage column 5. One end of the second connecting rod 43 is hinged to the other journal 411, and the other end of the second connecting rod 43 is hinged to the other extrusion plate 2. The extrusion plate 2 away from the massage column 5 has a clearance groove 22 for the second connecting rod 43 to pass through. The drive member 44 can drive the crankshaft 41 to rotate.

[0030] In specific implementation, the driving component 44 can be a motor, which controls the movement of the driving component 44. The driving component 44 drives the crankshaft 41 to rotate, and the crankshaft 41 drives the first connecting rod 42 and the second connecting rod 43 to move through two journals 411. When the journals 411 drive the first connecting rod 42 to move upward and the second connecting rod 43 to move downward, the distance between the two extrusion plates 2 increases. When the journals 411 drive the first connecting rod 42 to move downward and the second connecting rod 43 to move upward, the two extrusion plates 2 come into contact with each other. This drives the two extrusion plates 2 to move in opposite directions.

[0031] See Figures 1-4In other embodiments, a closing mechanism 7 is also included; the closing mechanism 7 includes a spring 71 and a closing plate 72; closing plates 72 are respectively provided on both sides of the swing direction of the second connecting rod 43, the closing plates 72 are slidably mounted on the pressing plate 2, and one end of the closing plate 72 abuts against the second connecting rod 43, and the other end of the closing plate 72 is provided with a spring 71, the spring 71 applies a spring force to the closing plate 72 towards the sliding of the second connecting rod 43, so that the closing plate 72 blocks the relief groove 22. Specifically, when the second connecting rod 43 swings, the second spring 71 pushes the closing plate 72 to always abut against the second connecting rod 43, thereby ensuring that the relief grooves 22 on both sides of the second connecting rod 43 are always blocked by the closing plates 72, thereby effectively preventing heat loss from the relief grooves 22.

[0032] See Figures 1-4 In other embodiments, the extrusion plate 2 with the clearance groove 22 has an installation cavity 23 on the side near the crankshaft 41. The installation cavity 23 communicates with the heating cavity 3, and the heater 6 is disposed in the installation cavity 23. In specific implementation, the heater 6 is installed in the installation cavity 23 to heat the gas in the heating cavity 3. The installation cavity 23 effectively ensures that there are no obstructions between the two extrusion plates 2, allowing them to abut against each other, thereby venting the gas in the heating cavity 3.

[0033] See Figures 1-4 In another embodiment, a tightening band 8 is also included, which is mounted on the housing 1. A push groove 12 is provided on the side of the housing 1 away from the massage column 5. The journal 411 can move outside the housing 1 through the push groove 12 to push the tightening band 8 toward the side away from the housing 1. In specific implementation, the tightening band 8 is mounted on the housing 1 to form a circle. The tightening band 8 is fitted onto the joint, so that the side of the housing 1 near the massage column 5 abuts against the joint, thereby fixing the housing 1 at the joint. When the crankshaft 41 rotates, the journal 411 moves outside the housing 1, and the journal 411 pushes the tightening band 8 to expand outward, so that the tightening band 8 can perform circumferential pressing on the joint, thereby further massaging the joint and improving blood circulation. Furthermore, multiple massage blocks 6 are installed on the inner side of the tightening band 8. The tightening band 8 drives the massage blocks 6 to squeeze and massage the joint, thereby improving the massage effect.
