Abstract
Description
Technical Field
[0001] This utility model relates to a massage device, specifically a foot massage and heating device. Background Technology
[0002] The soles of the feet are important reflex zones in the human body. Heating and massaging them can stimulate acupoints and promote circulation, which has significant health benefits. Existing technologies, such as the electrically heated foot massage device disclosed in CN209316446U, solve the problem of wire entanglement caused by the heating element's wires rotating with the massage rollers by utilizing the coordination of a support frame, a central rotating shaft, massage rollers, and an electrical supply device, along with the electrical connection between a conductive slip ring and an elastic electrode assembly. This achieves overall heating of the massage rollers and rolling heat therapy, improving the device's stability and heating effect.
[0003] However, this existing technology still has shortcomings in terms of heat distribution uniformity. The heat conduction path design of its heating components makes the heat distribution within the massage rollers prone to deviations. Some areas, being close to the heat source, experience localized overheating, which may cause user discomfort; while areas farther from the heat source receive insufficient temperature, failing to achieve the desired thermotherapy effect. This uneven temperature distribution prevents comprehensive and balanced heat stimulation of the soles of the feet, affecting both the thermotherapy effect and the user experience, and requires further improvement. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a foot massage and heating device that can make the heating effect more uniform and improve the user experience.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a foot massage and heating device, comprising a support frame; a rotating shaft rotatably connected to the support frame; a driving component linked to the rotating shaft for driving the rotating shaft to rotate; a massage wheel mounted on the rotating shaft and rotating with the rotating shaft; the massage wheel has an axially extending groove, and a protrusion is provided in the groove, the protrusion having a receiving groove; a heating element is provided in the receiving groove, and there is a gap between the protrusion and the outer shell of the massage wheel for massage.
[0006] As a further improvement of this utility model, a tensioning spring is also provided in the receiving groove. The tensioning spring is attached to one side of the heating element and uses its elasticity to attach the heating element to the outer shell side of the corresponding massage wheel in the receiving groove.
[0007] As a further improvement of this utility model, the tensioning spring is made of metal.
[0008] As a further improvement of this utility model, the raised side is provided with several connecting parts extending to the outer shell of the massage wheel, and the connecting parts are connected to the outer shell.
[0009] As a further improvement of this utility model, the protrusion is also provided with a second receiving groove, in which a temperature sensor or a temperature controller is provided. The temperature sensor or temperature controller works in conjunction with the heating element to start or stop heating.
[0010] As a further improvement of this utility model, a barrier plate is provided between the first receiving groove and the second receiving groove.
[0011] As a further improvement of this utility model, the protrusion is also provided with a receiving groove three, in which an insulating sleeve is placed, and the insulating sleeve is filled with a spring and a carbon brush. A conductive ring is provided on the support frame at the position corresponding to the carbon brush. The spring provides the carbon brush with elasticity to keep the carbon brush from abutting the conductive ring. The carbon brush, together with the conductive ring, supplies power to the heating component.
[0012] As a further improvement of this utility model, a temperature sensor is provided on the conductive ring to detect the ambient temperature of the conductive ring and to cooperate in controlling the power supply of the conductive ring.
[0013] As a further improvement of this utility model, a cover is provided at one end of the massage wheel corresponding to the conductive ring, and the cover is provided with a through hole for the carbon brush to extend from the carbon brush.
[0014] As a further improvement of this utility model, a notch is provided on one side of the receiving groove three for placing the wire. A baffle is provided on the cover at the position corresponding to the notch. When the cover is installed on the massage wheel, the baffle is located in the notch to prevent the spring and carbon brush from coming out of the notch, and the baffle and the bottom of the receiving groove three form a gap for the wire to extend.
[0015] The beneficial effects of this utility model are as follows: By setting an axial groove and a protrusion inside the massage wheel, the heating element is placed in the receiving groove of the protrusion, and a gap is maintained between the protrusion and the outer shell of the massage wheel. This avoids the heat of the heating element being directly concentrated and transferred to a local area of the outer shell. Through the buffering of the gap and the indirect conduction of the protrusion, the outer shell is heated more evenly, reducing the problem of local overheating or insufficient temperature, and improving the heating effect and user experience.

Detailed implementation manners
[0018] The following will further elaborate on the present utility model in conjunction with the embodiments shown in the drawings.
[0019] Refer to Figure 1-11 as shown A foot massage and heating device includes a support frame 1; a rotating shaft 2, rotatably connected to the support frame 1; a driving component 3, linked to the rotating shaft 2 and used to drive the rotating shaft 2 to rotate; a massage wheel 4, installed on the rotating shaft 2 and rotating with the rotating shaft 2; An axially extending groove 5 is provided inside the massage wheel 4, and a protrusion 6 is provided inside the groove 5. A first accommodating groove 7 is provided on the protrusion 6; a heating element 8 is provided inside the first accommodating groove 7. There is a gap between the protrusion 6 and the outer shell 9 of the massage wheel 4 for massage. The arrangement of the groove 5 and the protrusion 6 in this solution can also reduce the material cost and achieve the effect of saving materials. The massage wheel 4 in this solution is preferably made of a material with high thermal conductivity, such as high thermal conductivity resin or aluminum material.
[0020] The support frame 1 provides fixed support for the whole device and can be fixed on an external frame through bolts or the like; the rotating shaft 2 is rotatably connected to the support frame 1 and is also connected to the driving component 3 at the same time to ensure smooth rotation; the driving component 3 uses a motor, and the output shaft of the motor is linked with the rotating shaft 2 through gear meshing (including the worm and worm gear transmission method) or belt transmission. When the motor works, it drives the rotating shaft 2 to rotate around its own axis, and then drives the massage wheel 4 fixedly installed on the rotating shaft 2 to rotate synchronously, realizing the rolling massage of the feet. The outer shell 9 of the massage wheel 4 is the massage contact part that directly contacts the feet. Multiple massage protrusions can be installed on the outer shell 9. The massage protrusions and the outer shell 9 are preferably made of a material with high thermal conductivity, such as high thermal conductivity resin or aluminum material. A groove 5 extends axially inside the outer shell 9, and the protrusion 6 is integrally formed in the groove 5. The receiving groove 7 on the protrusion 6 is arranged axially. The heating element 8 uses an electric heating sheet (PTC heater) and is embedded in the receiving groove 7. After the heating element 8 is powered on, it generates heat. Since there is a gap between the protrusion 6 and the outer shell 9, the heat generated by the heating element 8 needs to be transferred to the protrusion 6 first, and then indirectly conducted to the outer shell 9 through the air between the protrusion 6 and the outer shell 9 and the edge of the protrusion 6, avoiding local overheating of the outer shell 9 caused by direct heat concentration transfer, making the temperature distribution in each area of the outer shell 9 more uniform, ensuring uniform heating of the foot contact area, and improving the heat therapy effect and user comfort.
[0021] In order to make the installation of the heating element 8 more stable, a tension spring piece 10 is also arranged in the receiving groove 7. The tension spring piece 10 is attached to one side of the heating element 8 and presses the heating element 8 against the corresponding side of the outer shell 9 of the massage wheel 4 in the receiving groove 7 through elastic force.
[0022] The tension spring piece 10 is made of an elastic metal sheet (such as a spring steel sheet) or a plastic sheet, and its shape is adapted to the inner wall of the receiving groove 7. When installed, one side of the tension spring piece 10 is attached to the inner wall of the receiving groove 7 away from the outer shell 9, and the other side is closely attached to the heating element 8. The tension spring piece 10 has an outward expanding elastic force in its natural state. After installation, the heating element 8 is tightly pressed against the inner wall of the receiving groove 7 close to the outer shell 9 through this elastic force, ensuring that the heating element 8 is in close contact with the inner wall of the receiving groove 7 and improving the heat transfer effect. This structure enables the heat generated by the heating element 8 to be more efficiently transferred to the wall surface of the receiving groove 7, and then conducted to the outer shell 9 through the gap between the protrusion 6 and the outer shell 9, avoiding problems such as low heat transfer efficiency and local temperature deviation caused by poor contact between the heating element 8 and the groove wall, further ensuring the uniformity of heat reception of the outer shell 9, and at the same time, the elastic force of the spring piece can improve the stability of the installation state of the heating element 8.
[0023] Preferably, the tension spring piece 10 is made of a metal material. The thermal conductivity of the metal material is better than that of the non-metal material, which can assist in transferring part of the heat of the heating element 8 to other areas of the first receiving groove 7, reducing the local heat accumulation of the heating element 8 itself, indirectly promoting the uniform distribution of heat in the protrusion 6, and further making the outer shell 9 receive heat more evenly, extending the service life of the device and ensuring the consistency of the heating effect.
[0024] In an alternative solution, a plurality of connecting portions 11 extending to the outer shell 9 of the massage wheel 4 are provided on the side surface of the protrusion 6, and the connecting portions 11 are connected to the outer shell 9.
[0025] A plurality of connecting portions 11 (such as strip-shaped rib plates) are formed by the side surface of the protrusion 6 extending radially. The end portions of the connecting portions 11 are integrally formed with the inner wall of the outer shell 9, so that the protrusion 6 and the outer shell 9 form a stable integral structure, enhancing the mechanical strength of the massage wheel 4 and preventing the massage wheel 4 from deforming due to stress during the rotation and massage process. At the same time, as an additional path for heat transfer, the connecting portions 11 can directly conduct the heat on the protrusion 6 to the outer shell 9, supplementing the heat transfer in the gap between the protrusion 6 and the outer shell 9, so that the area of the outer shell 9 far from the heating element 8 can also obtain heat through the connecting portions 11, reducing the temperature difference between different regions of the outer shell 9. For example, when the heating element 8 is located in the middle of the protrusion 6, the area of the outer shell 9 close to the heating element 8 is heated through the gap, and the area far from the heating element 8 obtains heat through the connecting portions 11, ensuring that the overall temperature distribution of the outer shell 9 is more uniform and improving the comprehensiveness of the heat therapy.
[0026] In order to achieve better temperature control, a second receiving groove 12 is also provided on the protrusion 6. A first temperature sensor 13 or a temperature controller is provided in the second receiving groove 12, and the first temperature sensor 13 or the temperature controller cooperates with the heating element 8 to start or stop heating.
[0027] The second receiving groove 12 is opened on the protrusion 6 and is spaced apart from the first receiving groove 7 by a certain distance. The first temperature sensor 13 (such as an NTC thermistor) is embedded in the second receiving groove 12. The first temperature sensor 13 is connected to an external controller through a wire and can detect the temperature in real time. It can be used to cooperate with the controller to prevent the temperature of the outer shell 9 from exceeding the safe range and causing burns to the user, and at the same time ensure that the temperature is maintained in the ideal heat therapy range, making the heating effect more controllable and improving the safety and user experience of the device.
[0028] Of course, the first temperature sensor 13 itself can integrate a controller to form a temperature controller. After forming the temperature controller, it can be connected according to the wire connection schematic shown by the dotted line in Figure 6 . The power supply enters the position of the heating element 8 after passing through the temperature controller, and the opening and closing of the heating element 8 are realized through the temperature detection and on-off control of the temperature controller itself.
[0029] Preferably, there is a partition plate 14 between the first receiving groove 7 and the second receiving groove 12. The partition plate 14 can be used to stabilize the installation of the first temperature sensor 13.
[0030] To make the power supply more convenient, a third receiving groove 15 is provided on the protrusion 6. An insulating sleeve 16 is placed in the third receiving groove 15. A spring 17 and a carbon brush 18 are filled in the insulating sleeve 16. A conductive ring 19 is provided on the support frame 1 at a position corresponding to the carbon brush 18. The spring 17 provides the elastic force for the carbon brush 18 to keep the carbon brush 18 in contact with the conductive ring 19; the carbon brush 18 cooperates with the conductive ring 19 to supply power to the heating component.
[0031] The third receiving groove 15 is opened at the end of the protrusion 6. The insulating sleeve 16 is made of insulating plastic and is embedded in the third receiving groove 15, playing an insulating and fixing role; the spring 17 and the carbon brush 18 are sequentially placed in the insulating sleeve 16. One end of the spring 17 abuts against the bottom of the insulating sleeve 16, and the other end abuts against the tail of the carbon brush 18, providing a continuous axial elastic force for the carbon brush 18. The conductive ring 19 on the support frame 1 is fixed by a bracket, and its axis coincides with the axis of the rotating shaft 2. The conductive ring 19 is connected to an external power supply. When the massage wheel 4 rotates, the carbon brush 18 is always in contact with the conductive ring 19 under the elastic force of the spring 17, forming a sliding electrical connection, so that the external power supply continuously supplies power to the heating element 8 through the conductive ring 19 and the carbon brush 18. This structure solves the problem of wire winding caused by the rotation of the heating element 8 with the massage wheel 4, ensures stable power supply, enables the heating element 8 to continuously and evenly generate heat, avoids temperature fluctuations caused by power supply interruption, and improves the working stability of the device.
[0032] In addition, regarding the solution of setting a temperature sensor on the massage wheel 4 mentioned above, the temperature sensor can also be set at the position of the conductive ring 19. For example, a second temperature sensor 24 is provided on the conductive ring 19 to detect the ambient temperature of the conductive ring 19. At the same time, a switch or a controller can be provided on the conductive ring 19 to cooperate with the temperature sensor 24 to control the on-off of the conductive ring 19, so as to control the on-off of the power supply of the heating element 8 on the massage wheel 4.
[0033] Preferably, a cover 20 is provided at one end of the massage wheel 4 corresponding to the conductive ring 19. A through hole 21 for the carbon brush 18 to extend out is provided at a position of the cover 20 corresponding to the carbon brush 18.
[0034] The cover 20 is made of plastic and needs to have insulation to avoid short - circuit or electric leakage caused by contact with the carbon brush. It is fixed to the end of the massage wheel 4 by a buckle or screws to close each receiving groove. The diameter of the through - hole 21 on the cover 20 is slightly larger than the diameter of the carbon brush 18. The end of the carbon brush 18 far from the spring 17 passes through the through - hole 21 and extends outside the cover 20 to contact the conductive ring 19 on the support frame 1. The cover 20 can prevent impurities such as dust and water vapor from entering the receiving groove three 15, avoiding contamination or corrosion of components such as the spring 17 and the carbon brush 18. At the same time, it restricts the axial displacement of the spring 17 and the carbon brush 18, ensuring that the carbon brush 18 is always aligned with the conductive ring 19 and preventing poor contact caused by component loosening. This structure ensures the stable contact between the carbon brush 18 and the conductive ring 19, ensuring continuous and reliable power supply, enabling the heating element 8 to work stably, and further ensuring the heating uniformity.
[0035] In a further setting, a notch 22 is provided on one side of the receiving groove three 15 for placing the wire. A baffle 23 is provided at the position corresponding to the notch 22 on the cover 20. When the cover 20 is installed on the massage wheel 4, the baffle 23 is located in the notch 22 to restrict the spring 17 and the carbon brush 18 from slipping out of the notch 22, and the baffle 23 and the bottom of the receiving groove three 15 form a gap for the wire to extend out.
[0036] A notch 22 is axially opened on the side of the receiving groove three 15. This notch 22 is used to accommodate the wire connecting the carbon brush 18 and the heating element 8, avoiding the wire being squeezed by the spring 17 or the carbon brush 18. When the cover 20 is installed, the baffle 23 on its inner side just inserts into the notch 22. The height of the baffle 23 is adapted to the depth of the notch 22, which can prevent the spring 17 and the carbon brush 18 from slipping out of the notch 22, ensuring the stable position of the components. At the same time, a gap is reserved between the baffle 23 and the bottom of the receiving groove three 15. The wire passes through this gap and extends out from the notch 22 and is connected to the heating element 8, which not only avoids the wire being squeezed and damaged by the baffle 23 but also restricts the shaking range of the wire. This structure ensures the stability and safety of the wire connection and ensures the smooth power supply circuit of the heating element 8.
[0037] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above - mentioned embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
