Description

Technical Field

[0001] The utility model relates to the field of foot massagers, in particular to a percussion type foot massager. Background Art

[0002] Most of the existing percussion type foot massagers achieve the percussion action by means of the motor shaft driving and connecting an eccentric shaft assembly and a percussion assembly. However, in the eccentric shaft assembly, power is transmitted to the eccentric rotating shaft through the meshing of multiple gears, which not only has a complex structure, numerous parts, and large space occupation, but also has poor earthquake and drop resistance, and the massager is prone to malfunction. For the existing foot massager with double percussion massage heads, most of its percussion assemblies use a V-shaped bracket to connect two percussion massage heads, and then connect the bracket through a rocker. The reciprocating movement of the rocker drives the bracket to swing, so as to realize the alternating percussion of the two percussion massage heads on the sole of the foot. The transmission by the swinging method cannot achieve high-frequency percussion, and the space occupied by the bracket in this structure is large, resulting in an increase in the thickness of the foot massager and poor portability.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following further describes the present utility model in detail with reference to the drawings and specific embodiments:

[0024] Refer to Figure 1 and Figure 2, A percussion type foot massager, comprising a housing assembly 10, a dual-axis motor 20 disposed within the housing assembly 10, two eccentric drive assemblies 30, a power supply assembly, and at least two percussion assemblies 50 that shuttle back and forth inside and outside the housing assembly 10. The two eccentric drive assemblies 30 are symmetrically disposed on both sides of the dual-axis motor 20. Each eccentric drive assembly 30 is fixedly connected to an output shaft of the dual-axis motor 20, and each eccentric drive assembly 30 is further rotatably connected to at least one percussion assembly 50. The dual-axis motor 20 is powered by the power supply assembly. By directly linking the two eccentric drive assemblies 30 with the dual-axis motor 20, there is no need to link the two symmetrically disposed drive assemblies through multiple gears, reducing the rotational speed consumption of the motor, thereby increasing the percussion frequency of the massager. At the same time, directly linking the two eccentric drive assemblies 30 with the dual-axis motor 20 also reduces the number of components and the occupied space, making the massager thinner and more resistant to dropping and shock.

[0025] In order to further reduce the complexity of the internal structure of the massager and the volume of the massager, this embodiment provides an implementation manner of an eccentric drive assembly 30 with a simple structure and less component usage. Please refer to Figure 3 and Figure 4 , In this embodiment, taking one eccentric drive assembly 30 driving two percussion assemblies 50 as an example, the two percussion assemblies 50 alternately strike the sole of the foot to improve the massage comfort. The eccentric drive assembly 30 includes a first crank connecting member 31, a crankshaft 32, a second crank connecting member 33, and a support member connected in sequence. Exemplarily, the support member includes a first bearing 34 and a first bearing sleeve 35. Both the first crank connecting member 31 and the second crank connecting member 33 are composed of a connecting rod and an eccentric wheel. The connecting rod of the first crank connecting member 31 is fixedly connected to an output shaft of the dual-axis motor 20. The eccentric rod of the first crank connecting member 31 is rotatably connected to one percussion assembly 50, and the eccentric rod of the first crank connecting member 31 is also fixedly connected to one end of the crankshaft 32. The other end of the crankshaft 32 is fixedly connected to the eccentric rod of the second crank connecting member 33. The eccentric rod of the second crank connecting member 33 is also rotatably connected to the other percussion assembly 50. The connecting rod of the second crank connecting member 33 is rotatably connected to the first bearing 34, and the first bearing sleeve 35 is fixed on the housing assembly 10.

[0026] Furthermore, please pay special attention to referring to Figure 3 and Figure 4, in order to avoid the vibration of the housing assembly 10 caused by the rotation of the eccentric drive assembly 30, in this embodiment, a shock-absorbing base 36 is installed in the housing assembly 10, and the shock-absorbing base 36 is fixed together with the housing assembly 10 to improve the stability of the massager during use. Specifically, the eccentric drive assembly 30 further includes a shock-absorbing base 36. The first crank connecting member 31, the crankshaft 32, the second crank connecting member 33, and the first bearing 34 are all installed in the shock-absorbing base 36, and the first bearing sleeve 35 is fixed on the shock-absorbing base 36. The support member is fixed to the housing assembly 10 through the shock-absorbing base 36; the first shock-absorbing sleeve 37 is fixed around the shock-absorbing base 36, and the first shock-absorbing sleeve 37 is fixedly connected to the housing assembly 10. As Figure 3 shown, the output shaft of the dual-axis motor 20 passes through the side wall of the shock-absorbing base 36, and the dual-axis motor 20 is fixed on the outer wall of one of the shock-absorbing bases 36, so as to realize the one-to-one correspondence between the shock-absorbing base 36 and the eccentric drive assembly 30.

[0027] Please refer to Figure 4 and Figure 5 , the knocking assembly 50 includes a knocking member 51 and a top push rod 52. The upper part of the knocking member 51 is a knocking head 511, and a connecting column 512 is horizontally arranged at the lower part. Connecting holes 521 are respectively provided at both ends of the top push rod 52. The connecting hole 521 at the upper end of the top push rod 52 is rotatably connected to the connecting column 512, and the connecting hole 521 at the lower end of the top push rod 52 is rotatably connected to the eccentric drive assembly 30. The knocking member 51 shuttles back and forth inside and outside the housing assembly 10 under the drive of the eccentric drive assembly 30. Specifically, the connecting hole 521 at the lower end of the top push rod 52 of one knocking assembly 50 is rotatably connected to the eccentric shaft of the first crank connecting member 31, and the connecting hole 521 at the lower end of the top push rod 52 of the other knocking assembly 50 is rotatably connected to the eccentric shaft of the second crank connecting member 33. The rotational connections between the top push rod 52 and the knocking member 51, and between the top push rod 52 and the eccentric shaft can all be realized by the second bearing 56 for a smoother rotational connection. Since the knocking assembly 50 shuttles up and down through the housing assembly 10 during operation and has a high shuttle frequency, it is easy to drive the housing assembly 10 to vibrate and is easy to cause wear between the knocking assembly 50 and the housing assembly 10. Therefore, the knocking assembly 50 further includes a fixing sleeve 53, a wear-resistant sleeve 54, and a second shock-absorbing sleeve 55. The fixing sleeve 53 is fixed at the lower part of the knocking member 51 to prevent the knocking member 51 and the top push rod 52 from colliding and rubbing against the housing assembly 10. Then, the fixing sleeve 53, the wear-resistant sleeve 54, and the second shock-absorbing sleeve 55 are sleeved layer by layer from the inside to the outside. The wear-resistant sleeve 54 and the second shock-absorbing sleeve 55 can both be fixed on the housing assembly 10, thus solving the problems of vibration and wear.

[0028] In this embodiment, the foot massager also adds a rolling massage function. Please refer to Figure 2 andFigure 5 The foot massager further includes a plurality of rolling massage components 60. Each rolling massage component 60 includes a massage roller 61 and a roller support seat 62. The roller support seat 62 is fixed within the housing assembly 10. The massage roller 61 is disposed on the roller support seat 62 and the upper part of the massage roller 61 is outside the housing assembly 10. The two ends of the massage roller 61 are rotatably connected to the support seat. The massage roller 61 applies pressure downward on the sole of the foot and slides back and forth, driving the massage roller 61 to roll while the roller massages the sole of the foot.

[0029] To further meet the multi-directional massage needs of users, this embodiment also adds the function of foot heating massage. Specifically, the rolling massage component 60 further includes a lamp board 63. The lamp board 63 is disposed in the inner cavity of the massage roller 61. The lamp board 63 is powered by the power supply component. The lamp beads on the lamp board 63 can use red light rice bulbs. The lamp beads or lamp cores on the lamp board 63 emit light and heat to achieve foot heating massage.

[0030] Please refer to Figure 1 and Figure 5 The power supply component includes a battery 41 and a charging control board 42 disposed within the housing assembly 10, and a button control board 43 disposed on the surface of the housing assembly 10. The charging control board 42, the battery 41, and the button control board 43 are electrically connected in sequence. The charging control board 42 is also electrically connected to a charging port, and an external power supply is connected through the charging port. The button control board 43 is electrically connected to the components that need electricity within the massager, and the on / off of the power supply circuit is controlled through the button control board 43. For example, the components that need electricity include the biaxial motor 20 and the lamp board 63. The power supply component can also adopt a direct plug-in power supply method, and an external power supply is connected to the button control board 43 through a power adapter to realize the on / off of the power supply to the internal electrical components of the massager.

[0031] Please refer to Figure 1 and Figure 5 In this embodiment, the housing assembly 10 includes a bottom cover 11 and an upper cover 12. The upper cover 12 is provided with first through holes 13 corresponding to the rolling massage components 60 one by one, second through holes 14 corresponding to the percussion components 50 one by one, and a third through hole 15 corresponding to the button control board 43.

[0032] The working process of the percussion type foot massager in this embodiment is as follows: After the dual-axis motor 20 is powered on, the output shaft drives the first crank connecting member 31 to rotate. The eccentric rod of the first crank connecting member 31 performs a circular motion. Since the eccentric rod is rotatably connected to the top push rod 52, the eccentric rod only drives the top push rod 52 to move up and down. At the same time, the eccentric rod on the second crank connecting member 33 performs a circular motion in the opposite direction through the crankshaft 32. Therefore, when the percussion assembly 50 on the first crank connecting member 31 moves upward, the percussion assembly 50 on the second crank connecting member moves downward, so as to realize the alternate percussion of the two percussion assemblies 50 on the soles of the feet. When roller massage is required, the power of the dual-axis motor 20 is turned off through the key control board 43, and the feet are slid back and forth for roller massage. At this time, the power of the lamp board 63 can also be turned on through the key control board 43 to realize heated roller massage, meeting the multi-faceted massage needs of users.

[0033] The above are only the specific embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
