[0018] Reference Figures 1 to 5A motor mounting structure of a juicer includes a base 1 on which a power supply unit 2 is mounted, the base 1 is provided with an inner cavity 13 for mounting electrical components, and a motor mounting seat 3 connected to the motor unit 2 is provided at the top of the inner cavity 13. The motor mounting seat 3 includes a mounting cavity 33 formed by a surrounding wall 31 and a plurality of mounting posts 32 evenly arranged around the surrounding wall 31. A through hole 34 is provided at the top of the mounting cavity 33 through which the power supply unit output shaft 21 passes. The top of the motor unit 2 extends into the mounting cavity 33 and the inner wall of the surrounding wall 31 cooperates with the outer wall of the motor unit 2. The side of the motor unit 2 is supported by the surrounding wall 31, and the limitation of the motor unit 2 is strengthened to avoid displacement caused by excessive torque when the motor is working. At the same time, it is also beneficial to the center positioning of the motor unit 2. The motor output shaft 21 of the motor component 2 passes through the base 1; a plurality of mounting lugs 22 are arranged around the side of the motor component 2 to cooperate with the mounting column 32, and a hole 221 is provided on the mounting lug 22, and a vibration-damping silicone ring 4 is mounted on the hole 221. The end of the mounting column 32 is inserted into the vibration-damping silicone ring 4 and then connected with a screw to connect and fix the motor component 2 to the mounting column 32. The vibration-damping silicone ring 4 can reduce the vibration transmission of the motor to the base 1, thereby avoiding noise problems caused by the working vibration of the motor.

[0019] The motor component 2 includes a motor reduction box 23 and a motor body 24. The motor reduction box 23 can increase the torque of the motor component 2, thereby better driving the screw to squeeze food; the motor body 24 is fixedly installed at the bottom of the motor reduction box 23, and the motor shaft penetrates into the motor reduction box 23 and is connected to the reduction mechanism. The motor output shaft 21 is arranged at the top of the motor reduction box 23. The motor body 24 drives the motor output shaft 21 to rotate by driving the reduction mechanism inside the motor reduction box 23; since the motor reduction box 23 occupies the top position of the motor component 2, the motor reduction box 23 extends into the installation cavity 33 and cooperates with the inner wall of the surrounding wall 31.

[0020] A plurality of locking ribs 25 are arranged circumferentially on the top of the motor component 2, and a plurality of slots 35 are provided in the installation cavity 33 to be locked with the locking ribs 25. After the top of the motor component 2 is installed in the installation cavity 33, the locking ribs 25 are locked in the slots 35 to prevent the motor component 2 from being displaced in the rotation direction when driven and subjected to force, so as to stably drive the screw to rotate to squeeze the food.

[0021] A positioning boss 26 is provided at the bottom of the motor component 2, and a recess 5 is provided at the bottom of the inner cavity 13 to cooperate with the positioning boss 26. After the positioning boss 26 is installed in the recess 5, it cooperates with the mounting cavity 33 at the top to limit the motor component 2 up and down, thereby improving the stability and concentricity of the motor operation. A vibration-damping sleeve 6 is provided on the positioning boss 26 and clamped between the positioning boss 26 and the recess 5, which can effectively prevent damage to the motor when the base 1 falls, and the vibration-damping sleeve 6 can also effectively reduce the vibration transmitted by the motor to the base 1.

[0022] The base 1 includes a shell body 11 and a bottom cover 12, wherein the bottom cover 12 is arranged on the bottom opening of the shell body 11 to form the inner cavity 13 inside the shell body 11, and the motor mounting seat 3 is arranged in the shell body 11. The recess 5 that cooperates with the bottom of the motor component 2 is arranged on the bottom cover 12. During assembly, the motor component 2 can be connected to the motor mounting seat 3 first, and then other electrical components can be installed in the inner cavity 13, and finally the bottom cover 12 can be replaced on the bottom opening of the shell body 11 by aligning the recess 5 with the positioning boss 26 at the bottom of the motor component 2.
