Description

Technical Field

[0001] This invention relates to the field of physiotherapy equipment technology, specifically a distributed physiotherapy device for hands and feet. Background Technology

[0002] High-frequency physiotherapy devices use high-frequency, high-voltage bioelectricity to cause charged particles and ion clusters in the body to spin and vibrate, making them easier to expel through capillary terminals and promoting cell metabolism and absorption. During use, the body needs to be in contact with the physiotherapy device.

[0003] However, most existing physiotherapy devices only contact the soles of the feet, providing full-body therapy. This results in low efficiency, slow speed, and poor therapeutic effects. Furthermore, the foot support structure of existing devices is unsuitable for different foot shapes, limiting their applicability and reducing user comfort. Additionally, existing physiotherapy devices are inconvenient to store, have poor heat dissipation, and shorten their lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide a distributed physiotherapy device for hands and feet, which can simultaneously treat the human body from the hands and feet. The physiotherapy is highly efficient and fast, effectively enhancing the therapeutic effect. It is also suitable for different foot types, expanding the applicability of the physiotherapy device and improving the comfort of use. It can also provide targeted heat dissipation for the heating components inside the physiotherapy device, effectively improving heat dissipation efficiency. At the same time, it has good dustproof effect, effectively extending the service life of the physiotherapy device, and is easy to adjust, use, and store.

[0005] A distributed physiotherapy device for hands and feet includes a base and a handle. A support structure for foot support is fixedly installed on the top of the base, a heat dissipation structure for heat dissipation is fixedly installed on the inner side wall of the base, and a storage structure for storing the handle is fixedly installed on one side inside the base.

[0006] The support structure includes an upper cover connected to the base. Conductive plates are installed on the two peaks of the upper cover, and a display screen is arranged between the two conductive plates. The two sides of the longitudinal section of the upper cover are inclined, and multiple heat dissipation holes are opened on both sides of the longitudinal section of the upper cover.

[0007] The heat dissipation structure includes multiple fans fixedly installed inside the base. A guide plate is provided on one side of each fan. The guide plate is connected to the base.

The conductive grip plate is electrically connected to the adjustment main board.

[0010] Furthermore, the display screen includes an acrylic protective plate fixedly connected to the top cover, and a liquid crystal display screen is fixedly connected below the acrylic protective plate. The top of the acrylic protective plate is U-shaped and matches the top cover, and all four corners of the acrylic protective plate are rounded.

[0011] Furthermore, the number of fans is four, with two fans on each of the front and rear sides of the base. The air guide plates are all located close to the inner sidewall of the base. The second guide plate includes two straight plates and one inclined plate. The two ends of the inclined plate are fixedly connected to the two straight plates respectively. The two straight plates are arranged opposite to the first guide plate.

[0012] Furthermore, the base is fixedly connected to a plurality of legs, which are arranged in a matrix at the bottom of the base (1). The height of the legs located on the front side of the base is higher than that of the legs located on the rear side of the base.

[0013] Furthermore, the storage compartment is U-shaped, with its opening located in the arc-shaped portion and fixedly connected to the base. The two vertical portions of the storage compartment are arranged facing the interior of the base, and the fixing magnet is located at one end of the two vertical portions of the storage compartment that are separated from each other.

[0014] Furthermore, the retrieval opening is T-shaped, with the horizontal portion of the retrieval opening located on the side of the base and the vertical portion of the retrieval opening located on the bottom surface of the base.

[0015] Furthermore, the take-up device includes a take-up housing, a fixed shaft is fixedly connected to the axis of the take-up housing, a rotating sleeve is rotatably sleeved on the outside of the fixed shaft, a spring is provided between the fixed shaft and the rotating sleeve, one end of the spring is fixedly connected to the fixed shaft, the other end of the spring is fixedly connected to the rotating sleeve, and the handle's connecting line is fixedly connected to the rotating sleeve.

[0016] Furthermore, the linkage mechanism includes an intermittent gear fixedly connected to one side of the handle.

The two linkage gears mesh with each other and are rotatably connected to the connecting beam.

[0017] Furthermore, the limiting mechanism includes a limiting pin with one end movably embedded in the connecting beam, the other end of the limiting pin intermittently contacting the limiting hole on the handle, the limiting pin being located near the toothless side of the intermittent gear, and a limiting groove being provided on the toothless side of the intermittent gear, the limiting pin sliding inside the limiting groove.

[0018] Furthermore, the limiting mechanism also includes a connector that is rotatably connected to the two handles at both ends. The connector is located on the side away from the linkage mechanism. A gear adjustment plate is provided between the connector and the handle. The gear adjustment plate is fixedly connected to the handle. The gear adjustment plate is U-shaped. The two vertical parts of the gear adjustment plate intermittently contact the connector. A steel ball is movably arranged between the gear adjustment plate and the connector. Multiple adjustment holes are provided on both the gear adjustment plate and the connector. The multiple adjustment holes are used to limit the steel ball. The connector is Z-shaped.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) In practical applications, the support structure is used for the base to support the feet. The top cover is arc-shaped and streamlined. The conductive plate is located at the two highest peaks of the top cover. When the user places their foot on the conductive plate, they can move their foot back and forth so that the palm of the foot can better contact the conductive plate. This is suitable for different foot shapes, expands the applicability of the physiotherapy device, and improves the comfort of use. The two sides of the longitudinal section of the top cover are inclined, which increases the area occupied by the heat dissipation holes, improves the heat dissipation effect inside the physiotherapy device, and reduces the noise generated by heat dissipation. The display screen is used to display relevant content of the physiotherapy device.

[0021] (2) In this distributed hand and foot physiotherapy device, multiple fans operate simultaneously, which effectively increases the airflow speed inside the base. The setting of the air guide plate enables the fans to provide targeted heat dissipation to the heat-generating components inside the base, effectively improving heat dissipation efficiency. Furthermore, the wide-angle structure formed by the first and second air guide plates effectively reduces dust from entering the base. This allows the air guide plate to play a dustproof role while also effectively increasing the airflow inside the base and improving heat dissipation.

[0022] (3) In this distributed hand and foot physiotherapy device, the opening of the storage compartment matches the retrieval port of the base, which facilitates the retrieval of the handle while making the base and the storage compartment form a relatively closed space, effectively reducing dust from entering the base. The storage compartment provides a certain degree of dust protection for the physiotherapy device. The fixed magnet, in conjunction with the magnet inside the handle, guides the handle when it is placed in the storage compartment. At the same time, the attraction of the fixed magnet to the magnet inside the handle provides a certain degree of fixation, preventing the handle from slipping out due to tilting of the physiotherapy device during movement, thus effectively improving the stability of the handle placed in the storage compartment. The cord retractor is used to store the handle connection cable. The handle connection cable passes through the cable hole of the storage compartment and connects to the cord retractor. The cord retractor provides convenience for storing the connection cable and avoids tangling, which would cause inconvenience in use.

[0023] (4) In this distributed hand and foot physiotherapy device, the user holds two handles and the hands are in contact with the conductive grips to perform physiotherapy on the hands. The main control board is connected to the host in the base through a connecting cable. The physiotherapy intensity of the handles can be adjusted by the buttons on the main control board, which is convenient and practical. When it is necessary to adjust the left and right opening angle of the two handles, only one handle needs to be rotated to adjust the hand direction. The other handle can automatically adjust the angle under the drive of the linkage mechanism, which is convenient. The limiting mechanism plays a limiting role in the adjustment of the left and right opening angle of the two handles, avoiding excessive adjustment of the opening angle of the handles, which would lead to inconvenience in use or even damage to the handles, and thus playing a certain protective role for the handles.

[0024] (5) This invention can provide physiotherapy to the human body from both the hands and feet at the same time. The physiotherapy is highly efficient and fast, effectively enhancing the therapeutic effect. It is also suitable for different foot types, expanding the applicability of the physiotherapy device and improving the comfort of use. It can also provide targeted heat dissipation to the heating components inside the physiotherapy device, effectively improving heat dissipation efficiency. At the same time, it has good dustproof effect, effectively extending the service life of the physiotherapy device. It is also easy to adjust, convenient to use and store.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1 to 14 A distributed physiotherapy device for hands and feet includes a base 1 and a handle 2. The top of the base 1 is equipped with a support structure for foot support, the inner side wall of the base 1 is equipped with a heat dissipation structure for heat dissipation, and one side inside the base 1 is equipped with a storage structure for storing the handle 2.

[0043] The support structure includes an upper cover 3 connected to the base 1. The upper cover 3 has an "m" shaped cross section. Conductive plates 4 are installed on both peaks of the upper cover 3. A display screen 5 is arranged between the two conductive plates 4. The upper cover 3 has an "n" shaped longitudinal section. The two sides of the longitudinal section of the upper cover 3 are inclined. Multiple heat dissipation holes 6 are opened on both sides of the longitudinal section of the upper cover 3.

[0044] The heat dissipation structure includes multiple fans 7 fixedly installed inside the base 1. A guide plate 8 is provided on one side of each fan 7. The guide plate 8 is connected to the base 1. The guide plate 8 includes a first guide plate 81 and a second guide plate 82 facing each other. The first guide plate 81 and the second guide plate 82 are respectively provided on both sides of one end of the fan 7.

[0045] The storage structure includes a retrieval port 10 opened on one side of the base 1. A storage compartment 11 for placing the handle 2 is fixedly connected to one side of the retrieval port 10 of the base 1. The storage compartment 11 is disposed inside the base 1. The opening of the storage compartment 11 matches the retrieval port 10. A fixing magnet 12 is installed inside the base 1. The fixing magnet 12 is disposed at one end away from the opening of the storage compartment 11. A cable retractor 13 for storing the connecting wire of the handle 2 is fixedly installed inside the base (1). The cable retractor 13 is disposed close to the storage compartment 11.

[0046] The handle 2 includes a connecting beam 14, with handles 15 rotatably connected to both ends of the connecting beam 14. A linkage mechanism is provided between the two handles 15, which is located on one side of the handle 15 and inside the connecting beam 14. A limit mechanism is provided between the handle 15 and the connecting beam 14. An adjustment main board 17 is fixedly installed inside the connecting beam 14. A conductive grip plate 16 is fixedly installed on the handle 15, and the conductive grip plate 16 is electrically connected to the adjustment main board 17.

[0047] In practical applications, the support structure is used to support the feet of the base 1. The upper cover 3 is arc-shaped and streamlined. The conductive plate 4 is located at the two highest arches of the upper cover 3. When the user places their foot on the conductive plate 4, they can move their foot back and forth so that the sole of the foot can better contact the conductive plate 4. This is suitable for different foot shapes, expands the applicability of the physiotherapy device, and improves the comfort of use. The two sides of the longitudinal section of the upper cover 3 are inclined, which increases the area occupied by the heat dissipation holes 6, improves the heat dissipation effect inside the physiotherapy device, and reduces the noise generated by heat dissipation. The display screen 5 is used to display relevant content of the physiotherapy device.

[0048] In this distributed hand and foot physiotherapy device, multiple fans 7 operate simultaneously, effectively increasing the airflow speed within the base 1. The arrangement of the air guide plate 8 allows the fans 7 to provide targeted heat dissipation to the heat-generating components within the base 1, effectively improving heat dissipation efficiency. Furthermore, the wide-angle structure formed by the first air guide plate 81 and the second air guide plate 82 effectively reduces dust entry into the base 1. Thus, while the air guide plate 8 serves a dustproof function, it also effectively increases the airflow within the base 1, improving heat dissipation.

[0049] In this distributed hand and foot physiotherapy device, the opening of the storage compartment 11 matches the retrieval port 10 of the base 1. This facilitates the retrieval of the handle 2 while creating a relatively enclosed space between the base 1 and the storage compartment 11, effectively reducing dust entry into the base 1. The storage compartment 11 provides a certain degree of dust protection for the physiotherapy device. The fixing magnet 12, in conjunction with the magnet inside the handle 2, guides the handle 2 when it is placed in the storage compartment 11. When the handle 2 is placed in the storage compartment 11, the attraction of the fixing magnet 12 to the magnet inside the handle 2 can play a certain role in fixing the handle 2, so that the handle 2 will not slip out due to the tilting of the physiotherapy device during movement, effectively improving the stability of the handle 2 placed in the storage compartment 11; the cord retractor 13 is used to store the connecting wire of the handle 2. The connecting wire of the handle 2 passes through the wire hole of the storage compartment 11 and is connected to the cord retractor 13. The cord retractor 13 provides convenience for storing the connecting wire and avoids the connecting wire from getting tangled, which would make it inconvenient to use;

[0050] In this distributed hand and foot physiotherapy device, the user holds two handles 15, with their hands in contact with the conductive grip plate 16 for hand physiotherapy. The main control board 17 is connected to the main unit inside the base 1 via a connecting cable. The physiotherapy intensity of the handle 2 can be adjusted using the buttons on the main control board 17, which is convenient and practical. When it is necessary to adjust the left and right opening angle of the two handles 15, only one handle 15 needs to be rotated to adjust the holding direction. The other handle 15 can automatically adjust its angle under the drive of the linkage mechanism, which is convenient. The limiting mechanism limits the left and right opening angle adjustment of the two handles 15, preventing excessive adjustment of the opening angle of the handles 15, which could lead to inconvenience or even damage to the handle 2, thus providing a certain degree of protection for the handle 2.

[0051] This invention can provide physiotherapy to the human body simultaneously from the hands and feet, resulting in high efficiency, speed, and enhanced therapeutic effects. It is also suitable for different foot types, expanding the applicability of the physiotherapy device and improving user comfort. Furthermore, it can provide targeted heat dissipation to the heating components within the device, effectively improving heat dissipation efficiency. It also has good dustproof properties, effectively extending the lifespan of the device, and is easy to adjust, use, and store.

[0052] Please see Figures 1 to 14The display screen 5 includes an acrylic protective plate 51 fixedly connected to the upper cover 3. A liquid crystal display screen 52 is fixedly connected below the acrylic protective plate 51. The top of the acrylic protective plate 51 is U-shaped and matches the upper cover 3. All four corners of the acrylic protective plate 51 are rounded. In this embodiment, since the plane of the liquid crystal display screen 52 is horizontal, but the upper cover 3 is curved and streamlined, the acrylic protective plate 51 effectively avoids a large drop caused by the mismatch between the shape of the liquid crystal display screen 52 and the upper cover 3. The U-shaped top of the acrylic protective plate 51, which matches the upper cover 3, can play a role in dust prevention and easy cleaning. The rounded corners of the acrylic protective plate 51 make it easier to fit the shape of the upper cover 3.

[0053] Please see Figures 1 to 14 The number of fans 7 is four, with two fans 7 arranged on each of the front and rear sides of the base 1. The air guide plates 8 are all located close to the inner sidewall of the base 1. The second guide plate 82 includes two straight plates 821 and one inclined plate 822. The two ends of the inclined plate 822 are fixedly connected to the two straight plates 821 respectively. The two straight plates 821 are positioned directly opposite the first guide plate 81. In this embodiment, two horizontally arranged fans 7 are used for air intake, and the other two fans 7 are used for air exhaust. Air intake and exhaust occur simultaneously, which helps to further accelerate the airflow within the base 1, thereby improving heat dissipation efficiency.

[0054] Please see Figures 1 to 14 The base 1 has multiple legs 9 fixedly connected to its bottom. These legs 9 are arranged in a matrix on the bottom of the base 1, with the legs 9 located at the front of the base 1 being higher than those located at the rear. In this embodiment, the legs 9 are evenly spaced on the bottom of the base 1, and based on the human sitting posture, the legs 9 located at the front of the base 1 are higher than those located at the rear, which improves user comfort.

[0055] Please see Figures 1 to 14 The storage compartment 11 is U-shaped, with its opening located in the arc-shaped portion and fixedly connected to the base 1. Two vertical sections of the storage compartment 11 face inwards towards the base 1, and the fixing magnet 12 is located at one end of each vertical section of the storage compartment 11. In this embodiment, the two handles 15 of the handle 2 are respectively placed inside the two vertical sections of the storage compartment 11. The storage compartment 11 guides and limits the handle 2, further improving the stability of the handle 2 within the storage compartment 11.

[0056] Please see Figures 1 to 14The retrieval opening 10 is T-shaped, with its horizontal portion located on the side of the base 1 and its vertical portion located on the bottom surface of the base 1. In this embodiment, when the handle 2 needs to be retrieved, the handle 2 is gripped from the vertical portion of the retrieval opening 10, causing the magnet of the handle 2 to disconnect from the fixed magnet 12, and the handle 2 is then pulled out of the storage compartment 11 from the horizontal portion of the retrieval opening 10 for easy removal.

[0057] Please see Figures 1 to 14 The take-up device 13 includes a take-up housing 131, with a fixed shaft 132 fixedly connected to the axis of the take-up housing 131. A rotating sleeve 133 is rotatably sleeved on the outside of the fixed shaft 132. A spring 134 is provided between the fixed shaft 132 and the rotating sleeve 133. One end of the spring 134 is fixedly connected to the fixed shaft 132, and the other end is fixedly connected to the rotating sleeve 133. The connecting line of the handle 2 is fixedly connected to the rotating sleeve 133. In this embodiment, the take-up housing 131 serves to limit and protect the connecting line. When the connecting line is pulled out from the outlet hole of the take-up housing 131, the rotating sleeve 133 rotates around the fixed shaft 132 and drives the spring 134 to tighten. When the connecting line is retracted, the spring 134 releases and drives the rotating sleeve 133 to rotate, thereby retracting the connecting line.

[0058] Please see Figures 1 to 14 The linkage mechanism includes an intermittent gear 25 fixedly connected to one side of the handle 15. Two intermittent gears 25 are positioned opposite each other on their toothed sides and each meshes with a linkage gear 18. The two linkage gears 18 mesh with each other and are rotatably connected to the connecting beam 14. In this embodiment, when one handle 15 is rotated, the handle 15 drives the intermittent gear 25 on the handle 15 to rotate relative to the connecting beam 14, thereby driving the linkage gear 18 to rotate. The linkage gear 18 then drives the intermittent gear 25 on the other handle 15 to rotate, thus achieving automatic angle adjustment of the other handle 15 when one handle 15 is rotated.

[0059] Please see Figures 1 to 14The limiting mechanism includes a limiting pin 19 with one end movably embedded in the connecting beam 14, and the other end of the limiting pin 19 intermittently contacts the limiting hole 20 on the handle 15. The limiting pin 19 is located near the toothless side of the intermittent gear 25, and the toothless side of the intermittent gear 25 is provided with a limiting groove 21. The limiting pin 19 slides inside the limiting groove 21. In this embodiment, the handle 15 has a plurality of limiting holes 20 on the side near the limiting pin 19. The plurality of limiting holes 20 are evenly spaced. The end of the limiting pin 19 near the handle 15 is in intermittent contact with the limiting holes 20 on the handle 15, which limits the angle of the two handles 15 during the opening and closing process. When the handle 15 is rotated to the maximum or minimum angle, the limiting pin 19 contacts the two sides of the limiting groove 21. The limiting groove 21 limits the maximum and minimum angles of the opening and closing of the two handles 15, thereby protecting the handle 2 during the angle adjustment process of the two handles 15 and preventing the two handles 15 from being too far apart or too close together and causing damage.

[0060] Please see Figures 1 to 14 The limiting mechanism further includes a connector 22 that is rotatably connected to the two handles 15 at both ends. The connector 22 is located on the side away from the linkage mechanism. A gear adjustment plate 23 is provided between the connector 22 and the handle 15. The gear adjustment plate 23 is fixedly connected to the handle 15. The gear adjustment plate 23 is U-shaped. The two vertical parts of the gear adjustment plate 23 intermittently contact the connector 22. A steel ball is movably arranged between the gear adjustment plate 23 and the connector 22. Multiple adjustment holes 24 are provided on both the gear adjustment plate 23 and the connector 22. The multiple adjustment holes 24 are used to limit the movement of the steel ball. In this embodiment, during the rotation of the handle 15, the gear adjustment plate 23 drives the steel ball (not shown in the figure) to roll between multiple adjustment holes 24. The multiple adjustment holes 24 limit the steel ball, thereby limiting the opening and closing angle of the two handles 15. When the handle 15 is rotated to the maximum or minimum angle, the two vertical parts of the "U"-shaped gear adjustment plate 23 intermittently contact the connector 22, thereby limiting the maximum and minimum opening and closing angles of the two handles 15 and preventing the two handles 15 from being too far apart or too close together, which could cause damage.

[0061] Please see Figures 1 to 14, the connecting member 22 is in a "几" shape. In this embodiment, when the two handles 15 are simultaneously folded in the up and down directions, the curved middle part of the connecting member 22 in the "几" shape increases the deformation tolerance of the connecting member 22, preventing the steel balls from disengaging from the connecting member 22 and the gear adjusting piece 23.

[0062] The above description is merely the preferred embodiment of the present invention, and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention shall all fall within the protection scope of the present invention.
