Description

Technical Field

[0001] This application belongs to the field of massage equipment technology, and more specifically, relates to a leg massager and a massage method. Background Technology

[0002] For leg massagers, the quality of the massage depends entirely on the appropriate depth. If the depth is too shallow, the desired massage effect will not be achieved, while if the depth is too deep, it will cause pain. Due to the difficulty in controlling the massage depth and the pain it causes to users, most leg massagers currently use massage airbags for massage. Although this method can provide users with a better user experience, the massage airbags are filled with air, so their pressure is insufficient, resulting in little relief after the massage.

[0003] Therefore, inventing a leg massager that can effectively control the depth of massage is an urgent problem to be solved. Summary of the Invention

[0004] The present invention aims to solve or improve at least one of the above-mentioned technical problems.

[0005] The first aspect of the present invention provides a leg massager.

[0006] A second aspect of the present invention provides a massage method.

[0007] The present invention provides a leg massager, comprising: a body having a placement groove for placing a leg; a cover for covering the body having a sliding groove; a slide plate disposed on the sliding groove and capable of sliding on the sliding groove; a sensor connected to the slide plate for detecting the distance between the sensor and the surface of the leg; and a massage component connected to the slide plate for lifting and lowering according to the distance and performing massage.

[0008] The leg massager provided by this invention includes a main body, a cover, a sliding plate, a sensor, and a massage component. The main body has a placement slot for the leg, and one end of the slot has a limiting plate to restrict the foot's movement. The cover fits onto the main body and has a sliding groove. The sliding plate is positioned on the sliding groove and can slide along it. The sensor is connected to the sliding plate and is used to detect the distance between the sensor and the leg surface. The massage component is connected to the sliding plate and can move up and down according to the distance between the sensor and the leg surface to perform massage. This invention uses a sensor to sense the distance between the sensor and the leg surface, indirectly sensing the height of the leg surface. This allows the massage component to move up and down based on changes in the sensor's distance, thus maintaining a consistent massage depth. It is understood that without a sensor, massage based solely on a pre-set trajectory would be difficult to maintain due to differences in leg shape and posture among users. This invention uses a sensor to sense changes in the user's leg height, ensuring a consistent massage depth and improving the user experience. Furthermore, this invention does not require a complex system, and compared to leg massagers that partially incorporate artificial intelligence for recognition, it significantly reduces production costs and improves production efficiency.

[0009] In one technical solution, optionally, the massage component includes: a lifting component, including a connector and a lifting member, the connector being connected to a sliding plate, and the lifting member being capable of lifting relative to the connector; a first connecting rod, one end of which is rotatably connected to the lifting member; and a massage part, connected to the other end of the first connecting rod.

[0010] In this technical solution, the massage component includes a lifting component, a first connecting rod, and a massage part. The lifting component includes a connector and a lifting member. The connector is connected to the slide plate, and the lifting member can move up and down relative to the connector. One end of the first connecting rod is rotatably connected to the lifting member. The massage part is connected to the other end of the first connecting rod. In this way, the lifting member can drive the massage part to move up and down, thereby ensuring a consistent massage depth.

[0011] In one technical solution, optionally, the leg massager further includes a heating device connected to the massage part for heating the massage part.

[0012] In this technical solution, the leg massager also includes a heating device connected to the massage unit for heating the massage unit. By using the heating device to heat the massage unit, the massage comfort can be improved. The heating device can be a resistance wire or similar component installed inside the massage unit.

[0013] In one technical solution, optionally, the massage part has an arc-shaped structure.

[0014] In this technical solution, the massage part has an arc-shaped structure. Optionally, the arc length of the arc-shaped structure is 15cm to 30cm. Setting the massage part to an arc-shaped structure allows it to fit the structure of the user's leg. Compared with massage rollers, this increases the massage area and reduces the pressure on the user's skin, thus improving the user's comfort.

[0015] In one technical solution, optionally, the massage component further includes: a second connecting rod, one end of which is rotatably connected to the lifting member; a third connecting rod, including a connecting end and two striking ends, the connecting end being rotatably connected to the second connecting rod; two striking parts, each connected to one of the two striking ends; and a driving device for driving the connecting end to reciprocate relative to the second connecting rod, so that the two striking parts alternately strike the leg.

[0016] In this technical solution, the massage component further includes a second connecting rod, a third connecting rod, and two tapping parts. One end of the second connecting rod is rotatably connected to the lifting member; the third connecting rod includes a connecting end and two tapping ends, with the connecting end rotatably connected to the second connecting rod; the two tapping parts are respectively connected to the two tapping ends; a driving device is used to drive the connecting end to reciprocate relative to the second connecting rod, so that the two tapping parts alternately tap the leg. It is understood that this invention can achieve both pressing and tapping massage functions. Since both the first and second connecting rods can be rotatably connected to the lifting member, when pressing massage is needed, the first connecting rod is rotated to the working position for massage via the massage parts; when tapping massage is needed, the second connecting rod is rotated to the working position for massage via the two tapping parts. This invention simultaneously possesses both pressing and tapping massage functions, improving the user experience. Furthermore, integrating the tapping and massage parts onto a single lifting member simplifies the lifting structure. In addition, a first motor can be configured for the first connecting rod to drive the first connecting rod to rotate relative to the lifting member, and a second motor can be configured for the second connecting rod to drive the second connecting rod to rotate relative to the lifting member.

[0017] In one technical solution, the massage part and the tapping part can be made of silicone.

[0018] In this embodiment, the massage and tapping parts are made of silicone, which makes them closer to human skin and improves the comfort of the massage.

[0019] In one technical solution, optionally, the outer surface of the lifting member is provided with a first thread, the inner surface of the connector is provided with a second thread, and the massage assembly further includes: a servo motor, which is mounted on the slide plate and can drive the connector to rotate so as to drive the lifting member to perform lifting and lowering movements through the first thread and the second thread.

[0020] In this embodiment, a first thread is provided on the outer surface of the lifting member, and a second thread matching the first thread is provided on the inner surface of the connecting member. The massage assembly also includes a servo motor, which is mounted on the slide plate and can drive the connecting member to rotate. Thus, under the action of the first and second threads, the lifting member can perform lifting and lowering movements, thereby ensuring the massage depth of the massage assembly.

[0021] In one technical solution, the sensor may optionally include one of an ultrasonic distance sensor, a laser rangefinder, and an infrared distance sensor.

[0022] The second aspect of the present invention provides a massage method, implemented by the leg massager provided in the first aspect of the present invention. The massage method includes: acquiring the distance between the sensor and the leg surface detected by the sensor; confirming the distance deviation based on the distance between the sensor and the leg surface and a standard distance; confirming the hysteresis interval of the massage part; and controlling the massage component to perform lifting and lowering movements after the hysteresis interval based on the distance deviation.

[0023] In one technical solution, optionally, the step of confirming the hysteresis interval of the massage part includes: obtaining the sliding speed of the slide plate; confirming the horizontal distance between the sensor and the massage part; and confirming the hysteresis interval of the massage part based on the sliding speed and the horizontal distance.

[0024] The massage method provided by the present invention is achieved by the leg massager provided in the first aspect of the present invention. Therefore, the massage method provided by the present invention has all the beneficial effects of the leg massager provided in the first aspect of the present invention, which will not be repeated here.

[0037] To better understand the above aspects, features, and advantages of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the embodiments of the present invention. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the embodiments of the present invention is not limited to the specific embodiments disclosed below.

[0039] Example 1

[0040] This invention provides a leg massager comprising a main body, a cover 2, a slide plate 3, a sensor 4, and a massage component 5. The main body is provided with a placement groove for placing the leg; the cover 2 can be closed onto the main body and is provided with a sliding groove 21; the slide plate 3 is disposed on the sliding groove 21 and can slide on the sliding groove 21; the sensor 4 is connected to the slide plate 3 and is used to detect the distance between the sensor 4 and the surface 7 of the leg; the massage component 5 is connected to the slide plate 3 and can move up and down according to the distance to perform massage.

[0041] like Figure 1 As shown, the leg massager provided by this invention includes a main body, a cover 2, a sliding plate 3, a sensor 4, and a massage component 5. The main body has a placement groove for the leg, and one end of the groove has a limiting plate for restricting the foot's position. The cover 2 can be fitted onto the main body and has a sliding groove 21. The sliding plate 3 is mounted on the sliding groove 21 and can slide on it. The sensor 4 is connected to the sliding plate 3 and is used to detect the distance between the sensor 4 and the leg surface 7. The massage component 5 is connected to the sliding plate 3 and can move up and down according to the distance to perform the massage function. By using a sensor 4, this invention can sense the distance between the sensor 4 and the leg surface 7, indirectly sensing the height of the leg surface 7. Therefore, based on changes in the distance between the sensor 4 and the leg surface 7, the massage component 5 can be controlled to move up and down, thus continuously maintaining the same massage depth. Understandably, without sensor 4, if massage is performed solely based on a pre-set trajectory, it's difficult to maintain a consistent massage depth due to variations in leg shape and posture among users. This invention uses sensor 4 to detect changes in the user's leg height, ensuring a uniform massage depth and improving user experience. Furthermore, this invention requires less complex systems, significantly reducing production costs and increasing efficiency compared to some leg massagers that rely on artificial intelligence for recognition.

[0042] Furthermore, a massage airbag is also provided on the inner surface of the placement slot. When the leg is placed inside the placement slot, the massage airbag can massage the sides and back of the leg. This invention uses the massage airbag and massage component 5 together to massage the leg, providing a comprehensive massage. Understandably, during massage, the massage part 54 of the massage component 5 and the massage airbag form a ring structure smaller than the user's leg. The massage part 54 of the massage component 5 massages the sides and front of the leg, while the massage airbag massages the sides and back of the leg, thus massaging the entire leg and improving the massage effect. Furthermore, the massage airbag can also limit the movement of the leg, improving massage efficiency.

[0043] In one technical solution, optionally, the massage component 5 includes a lifting component, a first connecting rod 53, and a massage part 54. The lifting component includes a connector 51 and a lifting member 52. The connector 51 is connected to the slide plate 3, and the lifting member 52 can move up and down relative to the connector 51. One end of the first connecting rod 53 is rotatably connected to the lifting member 52. The massage part 54 is connected to the other end of the first connecting rod 53.

[0044] In this technical solution, the massage component 5 includes a lifting component, a first connecting rod 53, and a massage part 54. The lifting component includes a connector 51 and a lifting member 52. The connector 51 is connected to the slide plate 3, and the lifting member 52 can move up and down relative to the connector 51. One end of the first connecting rod 53 is rotatably connected to the lifting member 52. The massage part 54 is connected to the other end of the first connecting rod 53. In this way, the lifting member 52 can drive the massage part 54 to move up and down, thereby ensuring a consistent massage depth.

[0045] In one technical solution, optionally, the leg massager also includes a heating device connected to the massage unit 54 for heating the massage unit 54.

[0046] In this technical solution, the leg massager also includes a heating device connected to the massage unit 54 for heating the massage unit 54. By using the heating device to heat the massage unit 54, the massage comfort can be improved. The heating device can be a resistance wire or the like installed inside the massage unit 54.

[0047] In one technical solution, optionally, the massage part 54 has an arc-shaped structure.

[0048] In this technical solution, the massage part 54 has an arc-shaped structure. Optionally, the arc length of the arc-shaped structure is 15cm to 30cm. Setting the massage part 54 to an arc-shaped structure allows the massage part 54 to be adapted to the structure of the user's leg. Compared with the massage roller, it increases the massage area and reduces the pressure on the user's skin, thereby improving the user's comfort.

[0049] In a technical solution, optional, such as Figure 2 As shown, the massage assembly 5 also includes a second connecting rod 55, a third connecting rod 56, and two tapping parts 57. One end of the second connecting rod 55 is rotatably connected to the lifting member 52. The third connecting rod 56 includes a connecting end and two tapping ends, with the connecting end rotatably connected to the second connecting rod 55. The two tapping parts 57 are respectively connected to the two tapping ends. The driving device is used to drive the connecting end to reciprocate relative to the second connecting rod 55 so that the two tapping parts 57 alternately tap the leg.

[0050] In this technical solution, the massage component 5 further includes a second connecting rod 55, a third connecting rod 56, and two tapping parts 57. One end of the second connecting rod 55 is rotatably connected to the lifting member 52; the third connecting rod 56 includes a connecting end and two tapping ends, with the connecting end rotatably connected to the second connecting rod 55; the two tapping parts 57 are respectively connected to the two tapping ends; a driving device is used to drive the connecting end to reciprocate relative to the second connecting rod 55, so that the two tapping parts 57 alternately tap the leg. It is understood that this invention can achieve both pressing massage and tapping massage functions. Since both the first connecting rod 53 and the second connecting rod 55 can be rotatably connected to the lifting member 52, when pressing massage is needed, the first connecting rod 53 is rotated to the working position, such as... Figure 3 As shown, massage is performed via the massage unit 54. When a tapping massage is required, the second connecting rod 55 is rotated to the working position, as shown. Figure 2 As shown, massage is performed through two tapping parts 57. This invention simultaneously possesses both pressing and tapping massage functions, improving the user experience. Furthermore, integrating the tapping parts 57 and the massage parts 54 onto a single lifting member 52 simplifies the lifting structure. Additionally, a first motor can be configured for the first connecting rod 53 to drive its rotation relative to the lifting member 52, and a second motor can be configured for the second connecting rod 55 to drive its rotation relative to the lifting member 52.

[0051] In one technical solution, optionally, both the massage part 54 and the tapping part 57 are made of silicone.

[0052] In this embodiment, the massage part 54 and the tapping part 57 are made of silicone, which makes the massage part 54 and the tapping part 57 closer to human skin and improves the comfort of the massage.

[0053] In one technical solution, optionally, a first thread is provided on the outer surface of the lifting member 52, and a second thread is provided on the inner surface of the connecting member 51, such as... Figure 8 As shown, the massage component 5 also includes a servo motor 58, which is mounted on the slide plate 3 and can drive the connector 51 to rotate so as to drive the lifting component 52 to move up and down through the first thread and the second thread.

[0054] In this embodiment, the outer surface of the lifting member 52 is provided with a first thread, and the inner surface of the connecting member 51 is provided with a second thread that matches the first thread. The massage assembly 5 also includes a servo motor 58, which is mounted on the slide plate 3 and can drive the connecting member 51 to rotate. Thus, under the action of the first thread and the second thread, the lifting member 52 can perform lifting and lowering movements, thereby ensuring the massage depth of the massage assembly 5.

[0055] In one technical solution, optionally, sensor 4 includes one of an ultrasonic distance sensor, a laser rangefinder, and an infrared distance sensor.

[0056] like Figure 4 As shown, the second aspect of the present invention provides a massage method, comprising the following steps:

[0057] S102: Obtain the distance between the sensor and the leg surface detected by the sensor;

[0058] S104: Based on the distance between the sensor and the leg surface and the standard distance, confirm the distance deviation;

[0059] S106: Confirm the lag time interval of the massage area;

[0060] S108: Based on the distance deviation, after a lag time interval, control the massage component 5 to perform lifting and lowering movements.

[0061] like Figure 5 As shown, in one technical solution, optionally, the step of confirming the hysteresis interval of the massage part includes the following steps:

[0062] S202: Obtain the sliding speed of the skateboard; confirm the horizontal distance between the sensor and the massage head;

[0063] S204: Based on the sliding speed and horizontal distance, confirm the hysteresis interval of the massage area.

[0064] The massage method provided by this invention includes: acquiring the distance between sensor 4 and the leg surface 7 detected by sensor 4; and confirming the distance deviation based on the distance between sensor 4 and the leg surface 7 and a standard distance. The standard distance is set within the system and is adjusted before massage. Specifically, the position of sensor 4 is fixed, and a plane containing a point on the leg surface 7 is selected as a reference plane 6. The distance between the position of sensor 4 and the reference plane 6 is then the standard distance. Figure 6As shown, if the plane containing point A is set as the reference plane 6, then the distance between sensor 4 and point A is the standard distance. After confirming the standard distance, adjust the massage component 5 to a suitable height to ensure a suitable massage depth. It is important to note that during the adjustment process, the skin surface point A corresponding to sensor 4 should be at the same height as the skin surface point C corresponding to massage part 54. After confirming the standard distance, the massage component 5 can be adjusted to a suitable height to ensure a standard massage depth. That is, when sensor 4 detects the standard distance, the corresponding massage part 54 is at the standard massage depth. Since the different positions on the leg are not on the same plane during the actual massage process, i.e., the heights are not the same, there will be a distance deviation. The distance deviation can also be understood as the change in height between a certain point on the leg surface 7 and the reference plane 6. After confirming the distance deviation of each position on the leg, the massage component 5 can be controlled to move up and down according to the distance deviation. Figure 7 When the massage reaches position B, sensor 4 scans point B. The difference between the distance between point B and sensor 4 and the distance between point A and sensor 4 at this point is the distance deviation. Knowing this distance deviation, the massage component 5 can be controlled to rise and fall after a lag interval. The height of the rise and fall is the distance deviation value, thus achieving the same massage depth. The lag interval of the massage component 5 is equal to the horizontal distance between sensor 4 and massage part 54 divided by the sliding speed of slide plate 3.

[0065] When controlling the massage component to rise and fall, since the present invention uses a servo motor 58 as the driving source for the lifting and falling motion, the servo motor 58 has the characteristic of precisely controlling the rotation angle. In actual operation, the height of the massage component to rise and fall is fixed when the shaft of the servo motor 58 rotates one revolution. Thus, when the distance deviation is known, the rotation angle of the shaft of the servo motor 58 can be indirectly calculated based on the distance deviation, and then the servo motor 58 is controlled to rotate according to this rotation angle, thereby completing the precise control of the lifting and falling height.
