Description

Technical Field

[0001] This invention relates to the technical field of massage devices, and in particular to a multifunctional foot massager. Background Technology

[0002] The feet are known as the "second heart" of the body, and the soles of the feet are reflex zones for many internal organs. Massaging acupoints on the feet can mobilize the body's internal potential, enhance the body's disease resistance, and regular foot massage can improve immunity and promote health. Foot massagers are health massage devices used to massage acupoints on the feet. By massaging these acupoints, fatigue can be relieved, tension can be soothed, and sleep can be improved, thereby improving overall health.

[0003] Existing leg and foot massagers include a housing, two massage units mounted on the housing, and a drive device that drives the two massage units to move. Each massage unit includes a massage chamber, a cam assembly located at the bottom of the massage chamber, and a transmission mechanism that connects the drive device and the cam assembly. The drive device drives the massage chamber to oscillate through the transmission mechanism and the cam assembly. The massage chamber is equipped with a massage head component that is connected to the transmission mechanism, so that the drive device drives the massage head component to massage synchronously while driving the massage chamber to oscillate.

[0004] However, the synchronous massage function of this foot massager is relatively simple, that is, the massage chamber swings and the massage head are activated simultaneously. This single massage function can no longer meet the user's requirements for foot massagers, so it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional foot massager, which allows users to choose between simultaneous massage of the massage rollers and massage chamber (the massage rollers rotate while the massage chamber oscillates) or massage of only the massage rollers, resulting in richer and more diverse massage functions and a better user experience.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a multifunctional foot massager, comprising... The casing has two massage chambers symmetrically arranged on it. The drive unit is located inside the housing; The transmission mechanism is located inside the housing and is connected to the drive unit for transmission. The massage mechanism has two sets, each corresponding to a massage chamber. The massage mechanism includes a drive shaft, cams, pressure covers, a universal drive device, and massage roller components. The drive shaft is rotatably mounted on the housing, and its lower end is connected to the transmission mechanism. The cams are mounted on the drive shaft via one-way bearings. The pressure covers are fixedly mounted on the upper end of the cams. An inclined mounting surface is provided on the upper end of the cams, forming an installation space between the inclined surface and the pressure covers. The base plate of the massage chamber is fitted within this installation space. The upper end of the drive shaft is connected to a universal drive device, the other end of which extends into the massage chamber and connects to the massage roller components. When the drive unit drives the transmission shaft to rotate in the forward direction, the cam rotates synchronously with the transmission shaft and drives the massage chamber to oscillate through the mounting inclined surface. At the same time, the transmission shaft drives the massage wheel component to rotate through the universal transmission device. When the drive unit drives the transmission shaft to rotate in the opposite direction, the transmission shaft only drives the massage wheel component to rotate through the universal joint transmission device, without driving the cam and massage chamber to move.

[0007] Furthermore, the universal drive device includes an input shaft, a universal joint, and an output shaft connected in sequence. The input shaft is fixedly installed on the upper end of the drive shaft, and the massage wheel component is fixedly installed on the upper end of the output shaft.

[0008] Furthermore, the massage chamber is provided with a receiving cavity for accommodating the human foot and an installation cavity located at the lower end of the receiving cavity. The installation cavity is isolated from the receiving cavity. The installation cavity is provided with an active tooth and at least one driven tooth. The active tooth is fixedly sleeved on the outer periphery of the output shaft of the universal transmission device. The driven tooth is rotatably disposed in the installation cavity through a rotating shaft and is connected to the active tooth for transmission. Massage wheel components are respectively installed on the upper end of the output shaft and the upper end of the rotating shaft.

[0009] Furthermore, the massage chamber is detachably equipped with a pedal located at the upper end of the base plate, and a mounting cavity is formed between the pedal and the base plate. The upper end of the output end and the upper end of the rotating shaft extend out of the pedal, respectively. The massage wheel component is on the output shaft and the rotating shaft and is located at the upper end of the pedal.

[0010] Furthermore, a guide plate located at the lower end of the active tooth is fitted around the outer periphery of the output shaft. The guide plate is fixedly connected to the bottom of the massage chamber, and a center hole with clearance fit to the output shaft is provided in the center of the guide plate.

[0011] Furthermore, the drive device includes a single motor, and two sets of transmission mechanisms are provided on both sides of the motor. The motor is connected to the transmission mechanisms on both sides, and transmission teeth are sleeved on the transmission shafts on both sides of the housing to be connected to the corresponding transmission mechanisms.

[0012] Furthermore, the massage chamber bottom plate has a downwardly protruding lower ring, and the lower ring has a receiving groove for accommodating the pressure cover. The lower end of the lower ring extends into the installation space and the bottom surface of the lower end abuts against the installation slope. The lower end of the lower ring has a clearance hole for the pressure cover and / or the cam portion to pass through.

[0013] Furthermore, the gap in the mounting space is slightly larger than the thickness of the lower end of the lower convex ring.

[0014] Furthermore, the center of the cam is provided with a mounting groove adapted to the one-way bearing, the bottom of the mounting groove is provided with a flange supporting the one-way bearing, the flange is provided with a through hole for the drive shaft to pass through, the pressure cap is fixedly connected to the upper end of the cam, and the pressure cap is provided with a limiting part that abuts against the upper end surface of the mounting groove.

[0015] Furthermore, a limiting post extends downward from the bottom of the massage chamber, and a limiting recess is provided on the housing. The limiting post extends into the limiting recess, and the swing range of the massage chamber is limited by the limiting cooperation between the limiting post and the limiting recess.

[0016] In summary, the present invention has the following beneficial effects: The foot massager of the present invention allows the user to control the simultaneous movement of the massage wheel component and the massage chamber or the movement of only the massage wheel component by steering the drive device. When the drive device drives the transmission shaft to rotate in the forward direction, the cam rotates synchronously with the transmission shaft and drives the massage chamber to swing and massage through the mounting inclined surface. At the same time, the transmission shaft drives the massage wheel component to rotate and massage through the universal transmission device. When the drive device drives the transmission shaft to rotate in the reverse direction, the transmission shaft drives the massage wheel component to rotate and massage only through the universal transmission device. Through the above settings, the foot massager has a richer and more diverse massage function and a better user experience. Attached Figure Description

[0025] The invention will now be further described with reference to the accompanying drawings.

[0026] like Figure 1-7 As shown, a multifunctional foot massager includes a housing 1, a drive device 3, a transmission mechanism 4, and a massage mechanism 5, which constitute the basic structure of the present invention.

[0027] Two massage chambers 2 are symmetrically arranged on the housing 1. A drive device 3 and a transmission mechanism 4 connected to the drive device 3 are provided at the bottom inner end of the housing 1. Two sets of massage mechanisms 5 are provided and correspond one-to-one with the massage chambers 2.

[0028] The massage mechanism 5 includes a drive shaft 51, a cam 52, a pressure cover 53, a universal drive device 54, and a massage wheel assembly 55. The drive shaft 51 is rotatably mounted on the housing 1. Specifically, the drive shaft 51 is rotatably mounted on the housing 1 via a bearing. The lower end of the drive shaft 51 is connected to the transmission mechanism 4. The cam 52 is mounted on the drive shaft 51 via a one-way bearing 56. The pressure cover 53 is fixedly mounted on the upper end of the cam 52. The upper end of the cam 52 is provided with an installation inclined surface 521. An installation space is formed between the installation inclined surface 521 and the pressure cover 53. The bottom plate 21 of the massage chamber 2 is fitted into the installation space. The gap of the installation space is slightly larger than the thickness of the bottom plate 21. The upper end of the drive shaft 51 is connected to the universal drive device 54. The other end of the universal drive device 54 extends into the massage chamber 2 and is connected to the massage wheel assembly 55.

[0029] When the drive unit 3 drives the transmission shaft 51 to rotate in the forward direction, the cam 52 rotates synchronously with the transmission shaft 51 and drives the massage chamber 2 to oscillate through the mounting inclined surface 521. At the same time, the transmission shaft 51 drives the massage wheel assembly 55 to rotate through the universal transmission device 54. That is, when the drive unit 3 rotates in the forward direction, the massage wheel assembly rotates and massages, and the massage chamber 2 oscillates and massages synchronously. When the drive unit 3 drives the transmission shaft 51 to rotate in the reverse direction, the transmission shaft 51 only drives the massage wheel assembly 55 to rotate through the universal transmission device 54, and does not drive the cam 52 and the massage chamber 2 to move. That is, when the drive unit 3 rotates in the reverse direction, only the massage wheel assembly rotates and massages.

[0030] The universal drive device 54 of the present invention is a non-constant speed universal drive device 54. The universal drive device 54 includes an input shaft, a universal joint and an output shaft 541 connected in sequence. The length of the input shaft is less than the length of the output shaft 541. The input shaft is fixedly installed on the upper end of the drive shaft 51. Specifically, the upper end of the drive shaft 51 is provided with a mounting port. The input shaft is inserted into the mounting port of the drive shaft 51. The connection method between the drive shaft 51 and the input shaft of the universal drive device 54 includes, but is not limited to, welding. The massage wheel component 55 is fixedly installed on the upper end of the output shaft 541.

[0031] When the drive device 3 rotates forward, the positions of the housing 1 and the drive shaft 51 rotatably mounted on the housing 1 are also fixed, while the massage chamber 2 will swing under the action of the mounting inclined surface 521 of the cam 52. When the user turns off the foot massager or pauses the forward rotation of the drive device 3, the massage chamber 2 will stay in any position. However, the position and angle between the massage chamber 2 and the drive shaft 51 are not fixed in different arbitrary positions. This invention connects the drive shaft 51 and the massage wheel component 55 through the universal transmission device 54. That is, the universal transmission device 54 allows the angle between the connected parts to change within a certain range, thereby allowing the massage chamber 2 to stay stationary at different positions within the set range. It can also transmit the power on the drive shaft 51 to the massage wheel component 55 through the universal transmission device 54.

[0032] The massage chamber 2 has a receiving cavity for accommodating the human foot and an installation cavity located at the lower end of the receiving cavity. The installation cavity is isolated from the receiving cavity. The installation cavity has an active tooth 23 and at least one driven tooth 24. The active tooth 23 is fixedly sleeved on the outer periphery of the output shaft 541 of the universal transmission device 54. The driven tooth 24 is rotatably disposed in the installation cavity through a rotating shaft and is connected to the active tooth 23. Massage wheel components 55 are respectively installed on the upper end of the output shaft 541 and the upper end of the rotating shaft. In this invention, there are two driven teeth 24, which are respectively located on both sides of the active tooth 23. The installation cavity has a rotating shaft corresponding to the driven teeth 24 one by one. The upper end of the rotating shaft and the upper end of the output shaft 541 are provided with massage wheel components 55. Due to the addition of massage wheel components 55, the foot massage area is greatly increased so as to massage multiple acupoints on the sole of the foot, thereby increasing the massage effect of the foot massager.

[0033] The massage chamber 2 is detachably equipped with a pedal 22 located on the upper end of the base plate 21. The pedal 22 and the base plate 21 form an installation cavity. The upper end of the output end and the upper end of the rotating shaft extend out of the pedal 22. Specifically, the pedal 22 is provided with a channel for the output shaft 541 to extend out. The diameter of the channel is larger than the outer diameter of the output shaft 541. The massage roller component 55 is on the output shaft 541 and the rotating shaft and is located on the upper end of the pedal 22. The pedal 22 separates the receiving cavity and the installation cavity to prevent the transmission components in the installation cavity from causing injury to the human foot.

[0034] The output shaft 541 is fitted with a guide plate 57 located at the lower end of the active gear 23. The guide plate 57 is fixedly connected to the bottom of the massage chamber 2. The center of the guide plate 57 is provided with a center hole that is clearance-fitted to the output shaft 541. That is, the output shaft 541 of the universal transmission device 54 is clearance-fitted with the center hole of the guide plate 57. The guide plate 57 can guide the output shaft 541 to ensure that the active gear 23 installed on the output shaft 541 is parallel to the base plate 21. In order to facilitate the installation of the guide plate 57, a positioning ring is protruding on the base plate 21. The lower part of the guide plate 57 is provided with a positioning flange 522 that is positioned and fitted with the positioning ring. The inner ring of the positioning flange 522 is adapted to the outer circumference of the positioning ring.

[0035] The drive device 3 includes a single motor, and the transmission mechanism 4 has two sets arranged on both sides of the motor. The motor is connected to the transmission mechanism 4 on both sides. The transmission shafts 51 on both sides of the housing 1 are fitted with transmission teeth that are connected to the corresponding transmission mechanism 4. The transmission mechanism 4 can be a gear set transmission or a worm gear and gear set transmission. The present invention uses a single motor to drive the transmission mechanism 4 on both sides to rotate, thereby driving the transmission shafts 51 on both sides to rotate. On the one hand, it drives the massage wheel component 55 connected to the transmission shaft 51 to rotate and massage, and on the other hand, it can drive the massage chamber 2 to swing and massage. Using a single motor drive can save costs and make the internal structure of the housing 1 more compact, occupy less space, and be easier to assemble.

[0036] The massage chamber 2 has a lower protruding ring 211 on the bottom plate 21. The lower protruding ring 211 has a receiving groove for accommodating the pressure cover 53. The lower end of the lower protruding ring 211 extends into the installation space and the bottom surface of the lower end abuts against the installation inclined surface 521. The lower end of the lower protruding ring 211 has a clearance hole for the pressure cover 53 or / and the cam 52 to pass through.

[0037] The gap in the installation space is slightly larger than the thickness of the lower end of the lower convex ring 211. This setting allows the bottom plate 21 of the massage chamber 2 to have a certain amount of room to move, which is conducive to the mounting slope 521 of the cam 52 driving the massage chamber 2 to swing, that is, it makes the swinging action of the massage chamber 2 more flexible.

[0038] The cam 52 has a mounting groove at its center that is adapted to the one-way bearing 56. The bottom of the mounting groove has a flange 522 that supports the one-way bearing 56. The flange 522 has a through hole for the drive shaft 51 to pass through. The pressure cover 53 is fixedly connected to the upper end of the cam 52. The pressure cover 53 has a limiting part 531 that abuts against the upper end face of the mounting groove. This setting facilitates the assembly of the one-way bearing 56. The mounting groove and the limiting part 531 cooperate to limit the one-way bearing 56 and prevent the one-way bearing 56 from shifting during the rotation of the drive shaft 51.

[0039] The bottom of the massage chamber 2 extends downward with a limiting post 25. The housing 1 is provided with a limiting recess. The limiting post 25 extends into the limiting recess. The swing range of the massage chamber 2 is limited by the limiting cooperation between the limiting post 25 and the limiting recess.

[0040] In summary, the present invention has the following beneficial effects: The foot massager of the present invention allows the user to control the drive device 3 to move the massage wheel component 55 and the massage chamber 2 simultaneously or only the massage wheel component 55 alone. When the drive device 3 drives the transmission shaft 51 to rotate in the forward direction, the cam 52 rotates synchronously with the transmission shaft 51 and drives the massage chamber 2 to swing and massage through the mounting inclined surface 521. At the same time, the transmission shaft 51 drives the massage wheel component 55 to rotate and massage through the universal transmission device 54. When the drive device 3 drives the transmission shaft 51 to rotate in the reverse direction, the transmission shaft 51 drives the massage wheel component 55 to rotate and massage only through the universal transmission device 54. Through the above settings, the foot massager has a richer and more diverse massage function and a better user experience.

[0041] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this patent application are included in the scope of this patent application.
