Description

Technical fields:

[0001] This utility model belongs to the field of massage equipment technology, and specifically relates to a foot massage mechanism. Background technology:

[0002] Most current foot massage techniques use rollers for the soles of the feet, combined with kneading pads for the arches and heels, or dual rollers for the soles and arches, and a kneading pad for the heels, creating a three-point massage. Because the soles of the feet have a large surface area, it's difficult for the rollers to fully contact their curved surfaces, resulting in a rather limited area receiving a massage.

[0003] The object of this invention is to find a more reasonable technical solution. Utility model content:

[0004] The purpose of this invention is to design a foot massage mechanism that uses surface contact massage for the sole of the foot.

[0005] The technical solution of this utility model is implemented as follows: A foot massage mechanism includes a motor, a gearbox, and a massage component mounted on a bottom shell. The motor drives the massage component to move after being reduced in speed by the gearbox. The massage component comprises a rotary massage head and a kneading plate. The rotary massage head has a massage surface and an eccentric cylinder offset at the bottom. A shaft hole is formed at the eccentric position of the eccentric cylinder, and the shaft hole is used to secure it to the output shaft of the gearbox. The kneading plate has a three-section structure: one end has a circular collar, the middle is arched to form an arch massage section, and the other end extends flat to form a heel massage section. The kneading plate is movably mounted on the eccentric cylinder via the circular collar, and a support and limiting mechanism is provided between the flat end and the bottom shell.

[0006] The supporting and limiting mechanism comprises a vertical shaft and / or a horizontal shaft, specifically as follows: 1. A vertical shaft, fixed to one side of the rubbing board or bottom shell, with a corresponding elongated groove in the front-to-back direction formed on one side of the bottom shell or rubbing board. The vertical shaft is inserted into the elongated groove to form a limiting position. A support ring is also formed on the vertical shaft, which is used to support the edge of the elongated groove. 2. A horizontal shaft, fixed to one side of the rubbing board or bottom shell, with a corresponding support groove formed on one side of the bottom shell or rubbing board.

[0026] Reference Figure 1 and Figure 2 The foot massage mechanism includes a motor 1, a gearbox 2, and a massage assembly mounted on the bottom shell 6. The massage assembly includes a rotary massage head 3 and a kneading board 4. The motor 1 is generally enclosed in the housing of the gearbox 2 to form an integrated structure. In this example, the motor 1 adopts a double-head output shaft. The gearbox 2 has two symmetrical speed transmission chains and two output shafts 21, which drive the two massage assemblies respectively to massage the soles of the feet.

[0027] The rotary massage head 3 has a massage surface 31 and an eccentric cylinder 32 offset at the bottom. A shaft hole 33 is formed at the eccentric position of the eccentric cylinder 32, and the shaft hole 33 is used to fix it onto the output shaft 21 of the gearbox. The massage surface 31 has a circular structure, the shaft hole 33 is located at the center of the circle, and several ball-shaped points 311 are raised on the upper surface. The circular massage surface 31 can keep the sole of the foot in the center during massage, so as to achieve the maximum area of ​​massage.

[0028] The kneading board 4 has a three-section structure: one end has a circular collar 41, the middle is arched to form an arch massage section 42, and the other end extends flat to form a heel massage section 43. The kneading board 4 is movably fitted onto the eccentric cylinder 32 by means of the circular collar 41. More specifically, a limiting plate 321 with a diameter larger than the diameter of the eccentric cylinder 32 is disposed at the lower end of the eccentric cylinder 32. The circular collar 41 of the kneading board is fitted onto the eccentric cylinder 32 and constrained within it by the limiting plate 321, which also forms a support. A support limiting mechanism 5 is provided between the flat end of the kneading board and the bottom shell 6, which constrains the reciprocating trajectory of this end. The support limiting mechanism is a vertical axis 51 and / or a horizontal axis 52, as detailed below:

[0029] 1. Vertical shaft 51 and horizontal shaft 52. The vertical shaft 51 is fixed to one side of the kneading board 4 or the bottom shell 6. A long groove 44 in the front-back direction is formed on one side of the bottom shell 6 or the kneading board 4, where front and back refer to the ball of the foot in front and the heel behind. In this example, the vertical shaft 51 is fixed to the bottom shell 6, and the long groove 41 is formed at the bottom of the kneading board 4. The vertical shaft 51 is inserted into the long groove 44 to limit the back-and-forth reciprocating motion. The horizontal shaft 52 is fixed to one side of the kneading board 4 or the bottom shell 6. A support groove 45 is formed on one side of the bottom shell 6 or the kneading board 4, and the horizontal shaft 52 is used to support the load. In this example, both the vertical shaft 51 and the horizontal shaft 52 are fixed to one side of the bottom shell 6, but they can also be set on the kneading board 4, or one shaft can be set for each.

[0030] Second, the vertical axis 51, which is a single vertical axis, is evolved from the above-mentioned dual-axis scheme. The vertical axis 51 is fixed to one side of the kneading board 4 or the bottom shell 6. A long groove 44 in the front-to-back direction is formed on one side of the bottom shell 6 or the kneading board 4. The vertical axis 51 is inserted into the long groove 44 to form a limit. A support ring is also formed on the vertical axis 51, which is used to support the edge of the long groove 44. Alternatively, a support block is formed on the bottom shell 6 corresponding to the edge of the long groove 44, which can also provide support.

[0031] Third, the horizontal axis 52, also a single horizontal axis, is derived from the first dual-axis scheme. The horizontal axis 52 is fixed to one side of the kneading plate 4 or the bottom shell 6, and a support groove 45 is correspondingly formed on one side of the bottom shell 6 or the kneading plate 4. A limiting ring is also formed on the horizontal axis 52, which slides into the long groove 44 on one side of the bottom shell 6 or the kneading plate 4 to form a limit. The limiting ring formed or locked on the horizontal axis 52 cooperates with the long groove 44 to form a limit for back-and-forth reciprocating motion.

[0032] Since the foot massage mechanism is installed on the bottom shell 6, only the bottom shell 6 is provided. The inner surface of the top cover is provided with an airbag and an opening for inserting both feet. With the help of the airbag, the feet can be pressed towards one side of the foot massage mechanism to achieve the need to adjust the massage intensity.

[0033] Reference Figure 3 and Figure 4 To achieve a better experience, the eccentricity R of the eccentric cylinder 32 of the rotary massage head is not less than 10mm; both the arch massage part 42 and the heel massage part 43 of the rubbing board are formed with massage protrusions 421. The arch massage part 42 has at least two rows of protrusions, which are higher on the inner side, with a height difference H1 not greater than 5mm. The "higher on the inner side" mentioned here refers to the inner side when the feet are facing each other, that is, the row with the inner side higher, which can target the highest point of the arch of the foot; the lowest massage protrusion 421 of the arch massage part 42 is higher than the massage protrusion of the heel massage part 43, with a height difference H2 not greater than 10mm, so that all parts of the curved surface of the sole of the foot can be contacted and effectively massaged.
