[0036] As shown in FIGS. 1-8, in a second aspect, the present disclosure provides a foot massager, and the foot massager includes all of structures of the foot massager of the embodiment 1. Furthermore, the upper cover assembly 100 comprises an upper cover 101, a top cover 102, a left foot pad 103, a right foot pad 104, a control panel 105, a display patch 106, and a light guiding piece 107. The foot massager further comprises an ornament 108 and a stainless steel trim 109. The upper cover 101 is installed on an upper end of the lower cover assembly 200. The top cover 102 is buckled with the upper cover 101. The left foot pad 103 and the right foot pad 104 are installed in the top cover 102. The control panel 105 and the display patch are sequentially disposed on a top surface of the top cover 102 from bottom to top. The light guiding piece 107 is disposed around the display patch 106. The ornament 108 and the stainless steel trim 109 are installed on one side of the upper cover assembly 100. The stainless steel trim 109 defines round holes configured to transmit sound.

[0037] Optionally, the lower cover assembly 200 comprises a lower cover 201, a shockproof base 202, anti-friction pads 203, a main board 204, a BLUETOOTH board 205, a speaker 206, and a direct current (DC) power socket 207. The lower cover 201 is buckled with the upper cover 101. The shockproof base 202 is installed on a lower surface of the lower cover 201. The shockproof base 202 is of an integrally formed structure and is made from rubber. The anti-friction pads 203 are installed on a bottom portion of the shockproof base 202.

Embodiment 4

[0041] As shown in FIGS. 1-8, in a fourth aspect, the present disclosure provides a foot massager, and the foot massager includes all of structures of the foot massager of the embodiment 3. Furthermore, each of the heating assemblies comprises an upper heating sheet fixing piece 13, a heat-conducting copper sheet 14, a middle heating sheet fixing piece 15, a heating sheet 16, and a lower heating sheet fixing piece 17.

[0042] In each of the heating assemblies, the middle heating sheet fixing piece 15 thereof is fixed on a corresponding one of the upper connecting rods 7, the heating sheet 16 thereof is fixed to the middle heating sheet fixing piece 15 thereof, the heat-conducting copper sheet 14 thereof is disposed on the heating sheet 16 thereof, the upper heating sheet fixing piece 13 thereof is disposed between the heating sheet 16 thereof and a corresponding one of the massage heads 10, and the lower heating sheet fixing piece 17 thereof is disposed between the heating sheet 16 thereof and a corresponding one of the connecting rod rubber pieces 11.

[0043] In each of the heating assemblies of the foot massager of the embodiment, the heat-conducting copper sheet 14 thereof conducts heat generated by the heating sheet 16 thereof to the corresponding one of massage heads to heat the feet of the user. In each of the heating assemblies, the upper heating sheet fixing piece 13 thereof isolates the heating sheet 16 thereof from a corresponding foot pad, so that the heating sheet 16 thereof does not directly contact the corresponding foot pad. In each of the heating assemblies, the lower heating sheet fixing piece 17 thereof isolates the heating sheet 16 thereof to prevent the heating sheet thereof from directly contacting the corresponding one of the connecting rod rubber pieces 11.

Embodiment 6

[0045] As shown in FIGS. 1-8, in a sixth aspect, the present disclosure provides a foot massager, and the foot massager includes all of structures of the foot massager of the embodiment 5. Furthermore, the foot massage assembly 300 further comprises bearing rubber sleeves 20 and motor bearings 19. The two ends of the motor shaft 4 are respectively installed in the bearing seats 18 through the motor bearings 19. The motor bearings 19 are 608ZZ bearings. Each of the bearing rubber sleeves 20 is sleeved on an outer ring of a corresponding one of the motor bearings 19 and are sleeved in an inner hole of a corresponding one of the bearing seats 18.

[0046] The motor bearings 19 respectively disposed on the two ends of the motor shaft of the brushless motor 2 are respectively sleeved in the bearing rubber sleeves 20. Since the motor shaft of the brushless motor 2 is too long, and there are some precision errors in processing or assembly technology, the brushless motor 2 and the two ends of the motor shaft may not be completely coaxial. If the two ends of the motor shaft are rigidly fixed, when the brushless motor 2 works, the two ends of the motor shaft 4 may generate opposite forces, which increase the noise generated by the movement of the brushless motor 2. The bearing rubber sleeves 20 that are flexible absorb the noise. The vibration generated when the foot massager massages the feet is acted on the motor shaft of the brushless motor 2 through the upper connecting rods 7. The flexible bearing rubber sleeves 20 disposed on the two ends of the motor shaft 4 further absorb vibration to the maximum extent and reduce the noise.

Embodiment 7

[0047] As shown in FIGS. 1-8, in a seventh aspect, the present disclosure provides a foot massager, and the foot massager includes all of structures of the foot massager of the embodiment 6. Furthermore, the foot massage assembly 300 further comprises sealed bearings 21 and pressing plates 22. The sealing bearings 21 are 6803ZZ bearings.
