At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0064] like Figures 1 to 5 As shown, the present invention provides a foot massager, comprising:

[0065] Base 1;

[0066] The driving device 2 includes a driving body 21, a first output shaft 22 and a second output shaft 23. The driving body 21 is disposed on the base 1, and the first output shaft 22 and the second output shaft 23 extend outwardly from the driving body 21;

[0067] The toe rolling combing mechanism 3 includes a rolling combing driving shaft 31, a rolling combing transmission assembly 32 and a rolling combing wheel 33. The rolling combing driving shaft 31 is rotatably arranged on the base 1 and is transmission-connected to the first output shaft 22 through the rolling combing transmission assembly 32. The rolling combing wheel 33 is arranged on the rolling combing driving shaft 31;

[0068] The arch scraping mechanism 4 includes a scraping screw 41, a scraping transmission assembly 42 with a clutch function, and a scraping seat 43. The scraping screw 41 is rotatably set on the base 1 and is transmission-connected to the second output shaft 23 through the scraping transmission assembly 42. The scraping seat 43 is threadedly penetrated by the scraping screw 41 and is moved on the base 1 in a direction parallel to the scraping screw 41.

[0069] In the present invention, since the rolling comb driving shaft 31 is rotatably arranged on the base 1 and is transmission-connected to the first output shaft 22 through the rolling comb transmission assembly 32, the driving device 2 transmits power to the rolling comb driving shaft 31 through its first output shaft 22, and under the driving action of the rolling comb driving shaft 31, the rolling comb wheel 33 arranged on the rolling comb driving shaft 31 performs a rolling comb massage action on the toes of the user's feet. Since the scraping screw 41 is rotatably arranged on the base 1 and is transmission-connected to the second output shaft 23 through the scraping transmission assembly 42, the driving device 2 transmits power to the scraping screw 41 through its second output shaft 23, and under the threaded cooperation of the scraping seat 43 and the scraping screw 41, the scraping seat 43 moves in a direction parallel to the scraping screw 41, and the scraping seat 43 performs scraping and acupressure massage actions on the soles of the user's feet. More importantly, the scraping transmission assembly 42 has a clutch function, that is, the scraping transmission assembly 42 can cut off or engage the transmission relationship between the second output shaft 23 and the scraping screw 41. In this way, without turning off the driving device 2, the toe rolling combing mechanism 3 can massage the user's feet at the same time as the arch scraping mechanism 4, and the toe rolling combing mechanism 3 can also massage the user's feet alone. The toe rolling combing mechanism 3 can switch between the running state and the stopped state at any time, so that the massage mode of the foot massager is varied. Therefore, the foot massager of the present invention drives the toe rolling combing mechanism 3 and the arch scraping mechanism 4 only by one driving device 2, and the toe rolling combing mechanism 3 can switch between the running state and the stopped state at any time, so that the massage mode of the foot massager is varied.

[0070] like Figure 3 As shown, in some embodiments, in order to improve the massage effect, the outer peripheral wall of the combing wheel 33 has a plurality of massage protrusions. The number of the combing wheels 33 is preferably two, and the two combing wheels 33 are symmetrically arranged on the combing drive shaft 31 and correspond to the two feet of the user one by one.

[0071] like Figure 5 As shown, in other embodiments, the scraping seat 43 includes a translation base 431 and two scraping plates 432, the translation base 431 is threadedly matched with the scraping screw 41, and the two scraping plates 432 are symmetrically arranged on the translation base 431 and correspond to the two feet of the user one by one. In a more preferred embodiment, the scraping plate 432 has a plurality of scraping convex bumps.

[0072] like Figure 4As shown, in order to realize the clutch function of the scraping transmission assembly 42, the scraping transmission assembly 42 includes an active transmission wheel 421, a driven transmission wheel 422, a clutch plate 423 and a repeller 424 that can attract or repel the active transmission wheel 421. The active transmission wheel 421 is slidably mounted on the second output shaft 23, the driven transmission wheel 422 is fixedly mounted on the scraping screw 41 and cooperates with the active transmission wheel 421 in transmission, the clutch plate 423 is arranged on the end of the second output shaft 23, and the repeller 424 is arranged on the side of the active transmission wheel 421 facing away from the driving body 21 to control the friction abutment between the active transmission wheel 421 and the clutch plate 423. In specific use, when the repellent 424 drives the active transmission wheel 421 to slide in one of the axial directions of the second output shaft 23, the active transmission wheel 421 and the clutch plate 423 are squeezed against each other in the axial direction of the second output shaft 23, that is, the active transmission wheel 421 and the clutch plate 423 are in friction contact, and the active transmission wheel 421 rotates along the fixed axis with the clutch plate 423, thereby causing the driven transmission wheel 422 to rotate along the fixed axis, thereby causing the scraping screw 41 to rotate along the fixed axis; when the repellent 424 drives the active transmission wheel 421 to slide in one of the axial directions of the second output shaft 23, the active transmission wheel 421 and the clutch plate 423 are in friction contact, and the active transmission wheel 421 rotates along the fixed axis with the clutch plate 423, thereby causing the driven transmission wheel 422 to rotate along the fixed axis, thereby causing the scraping screw 41 to rotate along the fixed axis; When the moving wheel 421 slides in the other direction of the axial direction of the second output shaft 23, a gap is generated between the active transmission wheel 421 and the clutch plate 423 in the axial direction of the second output shaft 23, and the active transmission wheel 421 does not rotate along the fixed axis with the clutch plate 423; when the repellent 424 neither attracts nor repels the active transmission wheel 421, there is no squeezing effect between the active transmission wheel 421 and the clutch plate 423 in the axial direction of the second output shaft 23, and the active transmission wheel 421 does not rotate along the fixed axis with the clutch plate 423.

[0073] Specifically, the scraping screw 41 includes a threaded section and an optical axis section, the scraping seat 43 is threadedly matched with the threaded section of the scraping screw 41, and the driven transmission wheel 422 is fixedly sleeved on the optical axis section of the scraping screw 41 through a connecting pin. In addition, the scraping transmission assembly 42 also includes a scraping assembly bracket, and the end of the scraping screw 41 is assembled on the scraping assembly bracket through a bearing.

[0074] The active transmission wheel 421 and the driven transmission wheel 422 can be gears or pulleys. When the active transmission wheel 421 and the driven transmission wheel 422 are both gears, the active transmission wheel 421 and the driven transmission wheel 422 are meshed with each other; when the active transmission wheel 421 and the driven transmission wheel 422 are both pulleys, the active transmission wheel 421 is connected to the driven transmission wheel 422 through a transmission belt.

[0075] In order to simplify the structure of the clutch plate 423, the clutch plate 423 includes a stopper plate 423a and a friction plate 423b. The stopper plate 423a is fixedly arranged on the end surface of the second output shaft 23, and the friction plate 423b is arranged on the side of the stopper plate 423a facing the driving body 21. In this embodiment, when the repellent 424 generates an attractive force on the active transmission wheel 421, the active transmission wheel 421 rotates along the fixed axis with the clutch plate 423. When the repellent 424 does not exert any force on the active transmission wheel 421, the active transmission wheel 421 does not rotate along the fixed axis with the clutch plate 423. The friction coefficient between the friction plate 423b and the active transmission wheel 421 should be high enough. When the repellent 424 causes the friction plate 423b and the active transmission wheel 421 to rub against each other, the static friction between the friction plate 423b and the active transmission wheel 421 can make the active transmission wheel 421 rotate along with the friction plate 423b.

[0076] In order to make the above-mentioned clutch plate 423 located in the active transmission wheel 421 and improve the compactness of the above-mentioned scraping transmission assembly 42, the above-mentioned active transmission wheel 421 is provided with a secondary stepped hole 425, and the secondary stepped hole 425 is composed of a small diameter hole and a large diameter hole; the above-mentioned second output shaft 23 is slidably penetrated in the small diameter hole, and the above-mentioned clutch plate 423 is located in the large diameter hole.

[0077] As an embodiment of the above-mentioned scraping transmission assembly 42: the above-mentioned active transmission wheel 421 includes a wheel body 421a and an armature piece 421b made of ferromagnetic material (such as metal materials such as iron, cobalt, nickel, etc.), the wheel body 421a is slidably sleeved on the second output shaft 23, and the armature piece 421b is arranged on the end face of the wheel body 421a facing away from the driving body 21; at this time, the above-mentioned repellent 424 can only generate attraction with the armature piece 421b, and the above-mentioned repellent 424 is an electromagnetic device, such as an electromagnet. When the electromagnetic device attracts the armature piece 421b, the attraction of the electromagnetic device to the armature piece 421b causes the wheel body 421a to rub against the clutch piece 423, so that the wheel body 421a rotates with the clutch piece 423 on a fixed axis; when the electromagnetic device does not attract the armature piece 421b, since there is no squeezing force between the wheel body 421a and the clutch piece 423, the clutch piece 423 cannot drive the wheel body 421a to rotate on a fixed axis.

[0078] like Figure 5As shown, in order to improve the accuracy of scraping the sole of the foot, the foot massager further includes a control system; the arch scraping mechanism 4 further includes a scraping position detector 47, which includes a plurality of magnet blocks 471 and a magnetic sensor 472. All magnet blocks 471 are arranged on the driven transmission wheel 422 and are arranged in a circumferential array with the wheel axis of the driven transmission wheel 422 as the center line. The magnetic sensor 472 is arranged at the periphery of the driven transmission wheel 422. When the driven transmission wheel 422 rotates with a fixed axis, the plurality of magnet blocks 471 distributed circumferentially on the driven transmission wheel 422 pass through the vicinity of the magnetic sensor 472 one by one in sequence, and the magnetic sensor 472 sends an induction signal to the control system, which determines the number of rotations and the rotation speed of the driven transmission wheel 422 according to the number and frequency of the received induction signals, and then calculates the moving distance, moving speed and current position of the scraping seat 43. Therefore, through the scraping position detector 47, the foot massager can adjust the scraping seat 43 to any position in the reciprocating motion stroke, so as to perform precise acupressure massage on the designated acupuncture points of the user's foot. The magnetic sensor 472 can be a circuit board with a magnetic sensing element. The number of the magnet blocks 471 can be four, six, or more.

[0079] like Figure 3 As shown, in order to improve the movement stability of the scraping seat 43, the arch scraping mechanism 4 also includes a scraping constraint mechanism 44, which includes a constraint frame 441 and a constraint shaft 442. The constraint frame 441 is arranged on the base 1 and has a constraint guide hole 441a extending in a direction parallel to the scraping screw 41, and the constraint shaft 442 is arranged on the scraping seat 43 and passed through the constraint guide hole 441a.

[0080] like Figure 5 As shown, in order to reduce the movement resistance between the scraping seat 43 and the base 1 , the scraping seat 43 is provided with a running wheel 45 that rolls with the base 1 .

[0081] like Figure 1 and Figure 2As shown, in order to improve the aesthetics, safety and comfort of the above-mentioned foot massager, the above-mentioned foot massager also includes a cover shell 5, which is connected to the base 1 up and down, and the cover shell 5 has a foot receiving groove 51 with a bottom opening, and a foot massager 52 is provided on the side wall of the foot receiving groove 51. There are two foot receiving grooves 51, and a comb wheel 33 and a scraping plate 432 are arranged at the bottom opening of each foot receiving groove 51. Specifically, the foot massager 52 can be a pressing airbag, which is inflated by inflation to press and massage the foot surface of the user's foot. In addition, in some embodiments, in order to further improve the comfort, two foot massagers 52 are provided in each foot receiving groove 51, and the two foot massagers 52 are symmetrically arranged on the inner side wall of the foot receiving groove 51 to perform a more comprehensive pressing massage on the foot surface of the user's foot.

[0082] In order to make the scraping seat 43 move within the preset stroke, the driving device 2 and / or the scraping transmission assembly 42 are connected to the control system; the arch scraping mechanism 4 also includes two travel switches 46 that limit the reciprocating stroke of the scraping seat 43, and the two travel switches 46 are arranged on both sides of the movement direction of the scraping seat 43 and are connected to the control system. When the scraping seat 43 moves to the limit position of the preset stroke, the scraping seat 43 will touch the travel switch 46, and the travel switch 46 sends a signal to the control system. After receiving the signal, the control system sends an instruction to the driving device 2 or the scraping transmission assembly 42 after processing. If the driving device 2 receives the instruction, the second output shaft 23 of the driving device 2 rotates in the opposite direction or stops rotating; if the scraping transmission assembly 42 receives the instruction, the scraping transmission assembly 42 cuts off the transmission relationship.

[0083] The above-mentioned rolling comb transmission assembly 32 is a worm gear mechanism, which includes a worm wheel and a worm in transmission connection. The worm is coaxially connected to the first output shaft 22, and the worm wheel is fixedly sleeved on the rolling comb driving shaft 31.

[0084] In summary, the foot massager of the present invention drives the toe rolling mechanism and the arch scraping mechanism through only one driving device, and the toe rolling mechanism can be switched between the running state and the stopping state at any time, so that the massage mode of the foot massager is varied. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0085] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
