The outer peripheral dimension of the upper rod portion 2211 is larger than the outer peripheral dimension of the lower rod portion 2212, and a portion of the bottom surface of the upper rod portion 2211, which is not connected to the lower rod portion 2212, abuts against the upper surface of the vibration-damping pad 40.

The quantity of mounting hole 321 is a plurality of respectively, and a plurality of mounting holes are along the even interval distribution of circumference, correspond in each mounting hole 321 to be provided with a damping pad 40.

The upper surface and/or the lower surface of the damping pad 40 is provided with a groove 41. Experiments prove that the vibration intensity transmitted from the motor 31 to the base 22 and/or the motor cover 21 can be reduced by arranging the grooves 41 on the upper surface and/or the lower surface of the vibration damping pad 40. The inventor of the present invention has studied and considered that the grooves 41 formed on the upper surface and/or the lower surface of the vibration damping pad 40 reduce the contact area between the vibration damping pad 40 and the base 22 and/or the motor cover 21, and further reduce the intensity of vibration transmitted to the base 22 and/or the motor cover 21 during the operation of the motor 31, so as to improve vibration generated during the operation of the housing 20 and improve noise generated by the vibration during the operation of the housing 20.

In one embodiment, as shown in FIG. 5, the grooves 41 on the damping pad 40 may extend in a straight line. Due to the arrangement, the groove 41 can be conveniently machined, and the process difficulty is reduced. In another embodiment, the groove 41 on the damping pad 40 may be curved. When the number of the grooves 41 is constant, the grooves 41 are arranged in an arc shape, which is more beneficial to reducing the contact area of the damping pad 40 with the base 22 and the motor cover 21, and is more beneficial to improving the vibration intensity of the base 20. Of course, in other embodiments, the groove 41 may have other shapes.

The upper surface and the lower surface of the vibration damping pad 40 can be respectively provided with a groove 41, so that the contact area between the upper surface of the vibration damping pad 40 and the base 22 is reduced, and the contact area between the lower surface of the vibration damping pad 40 and the motor cover 21 is also reduced, so that the vibration intensity transmitted to the motor cover 21 and the base 22 in the operation process of the motor 31 is reduced, and the vibration intensity of the base 20 is reduced.

The upper surface of the damping pad 40 can be provided with a plurality of grooves 41, and the plurality of grooves 41 arranged on the upper surface of the damping pad 40 are uniformly distributed along the circumferential direction; the lower surface of the damping pad 40 may be provided with a plurality of grooves 41, and the plurality of grooves 41 formed on the lower surface of the damping pad 40 are uniformly distributed along the circumferential direction. The upper surface or the lower surface of the vibration damping pad 40 is provided with a plurality of grooves 41, which is more beneficial to further reducing the contact area between the upper surface of the vibration damping pad 40 and the base 22 or between the lower surface of the vibration damping pad 40 and the top of the motor cover 21. The grooves 41 on the upper surface or the lower surface of the damping pad 40 are uniformly distributed along the circumferential direction, so that the damping pad 40 is uniformly stressed at all positions, and the damping pad 40 is prevented from being deformed due to local stress.

The thickness range of the upper part and the lower part of the vibration damping pad 40 exposed out of the mounting hole 321 is 1 mm-5 mm, and the depth range of the groove 41 is 0.2 mm-3.5 mm. Further, the depth of the groove 41 ranges from 1.5mm to 2mm, and may be, for example, 1.5mm, 1.7mm, 1.9mm, 2mm, or the like. So set up, can avoid leading to the part that damping pad 40 is located between two adjacent recesses 41 to be compressed because the degree of depth of recess 41 is too little, and then lead to the diapire of recess 41 and motor cover 21 or base 22 contact, and cause recess 41 can not effectively reduce the area of contact of damping pad 40 and base 22 or motor cover 21, also can avoid leading to the part between two adjacent recesses 41 to take place the slope when being extrudeed because the degree of depth of recess 41 is too big, and lead to damping pad 40's damping effect to reduce.

The groove 41 formed in the damping pad 40 includes two opposite ends, one end of the groove is communicated with the through hole 42, and the other end of the groove extends to the outer surface of the damping pad 40. This arrangement is more advantageous in reducing the contact area of the vibration damping pad 40 with the base 22 or the motor cover 21 when the number of the grooves 41 is fixed.

The vibration-damping pad 40 may include a main body portion 401, an upper swelling portion 402 formed by extending an upper end of the main body portion 401 outward, and a lower swelling portion 403 formed by extending a lower end of the main body portion 401 outward, the outer peripheral dimensions of the upper swelling portion 402 and the lower swelling portion 403 being larger than the inner diameter of the mounting hole 321, the main body portion 401 being received in the mounting hole 321, and the upper swelling portion 402 and the lower swelling portion 403 being exposed from the mounting hole 321. With such an arrangement, the damping pad 40 can be disposed more firmly in the mounting hole 321, and the damping pad 40 is prevented from being separated from the mounting hole 321. The upper surface of the upper enlarged portion 402 is the upper surface of the vibration damping pad 40, and the lower surface of the lower enlarged portion 403 is the lower surface of the vibration damping pad 40.

The damping pad 40 may be made of silica gel or other materials with high elasticity and low deformation tendency.

The motor assembly 30 can be used not only in the base 20 of the food processor 100, but also in other products outside the food processor, and can achieve a better vibration damping effect, and thus is also within the protection scope of the present application.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
