In some embodiments, the damping recess 29 is provided on a circumference having a diameter ranging from 110mm to 118mm with the center of the shaft center of the motor shaft 21 as a center. For example, the center line of the shock absorbing groove 29 may be disposed on a circumference having a diameter of 110mm, 112mm, 114mm, 116mm, 118mm, but is not limited thereto. Accordingly, the circumference of the shock absorbing boss 28 corresponds to the circumference of the shock absorbing groove 29, so as to ensure the smooth matching between the shock absorbing boss 28 and the shock absorbing groove 29. The larger the diameter of the circumference in which the damper groove 29 is located, the closer the damper groove 29 is to the rim of the mixing cup 12, and accordingly, the more stable the engagement with the damper boss 28.

In some embodiments, the width dimension of the damping recess 29 in the radial direction of the motor shaft 21 ranges from 10mm to 18mm, and the damping boss 28 is clearance-fitted to the damping recess 29. For example, the radial width dimension of the shock absorbing groove 29 may be 10mm, 12mm, 14mm, 16mm, 18mm. The radial width dimension of the damping groove 29 is small, the radial width dimension of the damping boss 28 is correspondingly small, the radial width dimension of the damping groove is selected within the range of 10 mm-18 mm, the radial width dimension of the damping boss 28 can be prevented from being too small, and the strength and the pressure resistance of the damping boss 28 can be improved.

In some embodiments, the damping grooves 29 do not meet end to end, and the depth dimension of the damping grooves 29 at the smallest depth is not less than 1mm and the depth dimension at the largest depth is not less than 4mm in the direction around the motor shaft 21. Therefore, the situation that the shock absorption groove 29 is too small in depth and separated from the shock absorption boss 28 can be avoided, and the reliability of inserting the shock absorption boss 28 into the shock absorption groove 29 is improved.

In some embodiments, the main machine 11 further comprises a cup seat 14 made of a flexible material, the cup seat 14 being assembled between the blender cup 12 and the main machine 11.

The flexible material may include, but is not limited to, polyvinyl alcohol, polyester, polyimide, polyethylene naphthalate, and the like.

Referring to fig. 16 to 20, fig. 16 is a schematic view of a first surface of the cup seat 14 shown in fig. 3. Fig. 17 is a schematic view of a second surface of the cup holder 14 shown in fig. 16. Fig. 18 is a front view of the cup holder 14 shown in fig. 16. Fig. 19 shows a side view of the cup holder 14 shown in fig. 16. Fig. 20 is a partial cross-sectional view of the cup seat 14 shown in fig. 3 disposed between the blending cup 12 and the main body 11.

The cup seat 14 is disposed between the main body 11 of the food processor 10 and the stirring cup 12, and is made of a deformable elastic material, which includes but is not limited to silica gel, polyethylene, and the like. In one embodiment, the coaster 14 is assembled on top of the host computer 11 and conforms to the shape of the top of the host computer 11.

As shown in fig. 16 and 17, the coaster 14 includes a first surface 141 and a second surface 142 in a thickness direction, the first surface 141 being for contact with the mixing cup 12, and the second surface 142 being for contact with the main body 11. In the embodiment shown in fig. 16, the first surface 141 of the cup seat 14 is formed with a convex portion 275, the second surface 142 of the cup seat 14 is formed with a concave portion 143 corresponding to the convex portion 275, the convex portion 275 is hollow, the shock absorbing boss 28 is embedded in the concave portion 143 and covered by the convex portion 275, and the cup seat 14 is clamped between the main body 11 and the mixing cup 12, thereby improving the shock absorbing effect.

In one embodiment, the first surface 141 is formed with a first shock absorbing protrusion 145, and the cup holder pad 14 further includes a motor shaft hole 147 at a central region and a coupler hole 60 at an edge region, wherein the motor shaft hole 147 and the coupler hole 60 penetrate in a thickness direction of the cup holder pad 14, the motor shaft hole 147 is passed through by the motor shaft 21, and the coupler hole 60 is passed through by the coupler 50. The first shock-absorbing projection 145 is provided at a side of the coupler hole 60 away from the motor-shaft hole 147.

In practical application scenarios, after the cup mat 14 is installed on the host 11, the first shock absorption protrusion 145 on the cup mat 14 can absorb and relieve shock, so that shock generated by the host 11 and the stirring cup 12 at the first shock absorption protrusion 145 can be reduced. For example, the first shock absorbing protrusions 145 may be aligned with the handle 122 of the cup body 24 in the height direction of the cup body 24, thereby providing a better shock absorbing effect at the handle 122. It should be noted that the second surface 142 may also be provided with a first shock absorbing protrusion 145.

The first shock absorbing protrusion 145 may include a plurality of first sub-protrusions 146, the plurality of first sub-protrusions 146 are distributed around the center of the motor shaft hole 147 in a plurality of rows, and along the circumferential direction of the motor shaft hole 147, the plurality of first sub-protrusions 146 are distributed in a concentrated manner in a region facing the coupler hole 60 in the radial direction of the motor shaft hole 147. The plurality of first sub-protrusions 16 separated from each other are more flexible, more deformable, and more shock-absorbing than the protrusions of the unitary structure, and can better absorb and absorb shock and impact at the periphery of the coupler hole 60. In the embodiment shown in fig. 16, the plurality of first sub-protrusions 146 are arranged in three rows around the center of the motor shaft hole 147, and each row is provided with three first sub-protrusions 146, but is not limited thereto.

In one embodiment, the first shock absorbing protrusion 145 further includes an arc-shaped strip-shaped protrusion 1491 disposed on the first surface 141, and the plurality of first sub-protrusions 146 protrude from the arc-shaped strip-shaped protrusion 1491. The arc-shaped strip-shaped protrusions 1491 can increase the thickness of the cup pad 14 at the first shock absorbing protrusion 145, thereby increasing the strength of the area and reducing the risk of crushing and breaking the area while maintaining the elastic deformation.

The shape and size of the first sub-protrusion 146 are not limited. In one embodiment, the plurality of first sub-protrusions 146 are cylindrical protrusions having a diameter ranging from 3mm to 7mm. For example, the diameter of the cylindrical protrusion may be 3mm, 4mm, 5mm, 6mm, 7mm. The range of the height of the first sub-protrusions 146 protruding out of the surface of the arc-shaped strip-shaped boss 1491 is 1 mm-3 mm. For example, the protrusion heights of the plurality of first sub-protrusions 146 are equal and may be 1mm, 2mm, or 3mm. The larger the diameter of the first sub-protrusions 146 is, the less the amount of the elastic deformation is, the less the ability to absorb the impact and shock is, while the smaller the diameter of the cylindrical protrusion is, the greater the amount of the elastic deformation is, the better the ability to absorb the impact and shock is, but the lower the strength is, and the easier it is to break. Similarly, the higher the height of the first sub-protrusions 146, the greater the amount of elastic deformation, and if the height of the first sub-protrusions 146 is too high, the strength is low, and the probability of breakage or fracture is high. Therefore, it may be selected within the above size range, for example, when the height of the first sub-protrusion 146 is 1mm, the diameter may be set to 3mm, 4mm, or 5mm. When the height of the first sub-protrusion 146 is 3mm, the diameter may be set to 5mm, 6mm, or 7mm. Thus, it is possible to secure both the elastic deformation amount of the first sub-protrusion 146 and the strength of the first sub-protrusion 146.

In one embodiment, the size of the arc strip-shaped protrusion 1491 in the circumferential direction of the motor shaft hole 147 ranges from 50mm to 80mm, and the size of the arc strip-shaped protrusion 1491 in the radial direction of the motor shaft hole 147 ranges from 20mm to 30mm. For example, the arc-shaped strip-shaped protrusion 1491 may have an outer arc length of 50mm and a radial dimension of 30mm, or an outer arc length of 80mm and a radial dimension of 20mm, but is not limited thereto. The circumferential dimension and the radial dimension of the arc-shaped strip-shaped boss 1491 are set in the range, so that the peripheral space of the coupler hole can be effectively utilized, the shock absorption can be realized, and the interference can be avoided.

In one embodiment, the length of the arc-shaped strip-shaped protrusion 1491 in the circumferential direction of the motor shaft hole 147 exceeds the length of the coupler hole 60 in this direction by at least 2mm. This increases the circumferential length of the arcuate strip 1491, which dampens and absorbs shock over a greater area around the coupler bore 60.

It should be noted that the second surface 142 may be provided with an arc-shaped strip-shaped boss, and the first shock absorption protrusion is disposed on the arc-shaped strip-shaped boss and protrudes to a side away from the first surface 141.

In some embodiments, the cup pad 14 further includes a second shock absorbing protrusion 148 formed on the first surface 141, and the second shock absorbing protrusion 148 is disposed at an edge of the motor shaft hole 147 around a center of the motor shaft hole 147. The vibrations that produce when second shock attenuation arch 148 can be alleviated and absorb arbor 131 and the transmission of motor shaft 21 further improve cooking machine 10's shock-absorbing capacity, promote user experience.

In one embodiment, the second shock absorbing protuberances 148 include a plurality of second sub-protuberances 1480, and the second sub-protuberances 1480 have tops separated from each other and bottoms connected. The plurality of second sub-protrusions 1480 are mainly used for relieving and absorbing shock through the tops, the deformation amount of the plurality of second sub-protrusions 1480 can be increased by separating the plurality of second sub-protrusions 1480 at the tops, the strength and the rigidity can be increased by connecting the plurality of second sub-protrusions 1480 at the bottoms, and fatigue failure of the plurality of second sub-protrusions 1480 under the action of pressure is avoided.

In one embodiment, a gap 310 is left between the tops of two adjacent second sub-protrusions 1480, and the length of the gap 310 in the circumferential direction of the motor shaft hole 147 ranges from 2mm to 3mm, for example, the circumferential length may be 2mm or 3mm, but is not limited thereto. The width of the gap 310 in the radial direction of the motor shaft hole 147 ranges from 4mm to 6mm, and for example, the radial width is 4mm, 5mm, or 6mm, but is not limited thereto. The height of the gap 310 in the axial direction of the motor shaft hole 147 is in a range of 5mm to 8mm, for example, 5mm, 6mm, 7mm, and 8mm, but is not limited thereto. Therefore, a sufficient deformation space can be provided for the plurality of second sub-protrusions 1480, the size of the gap 310 is selected within the range, on one hand, the small deformation caused by the undersize of the gap 310 can be avoided, on the other hand, the overlarge size and strength reduction of the gap 310 can be avoided, and therefore the shock can be better relieved and absorbed, and the shock absorption effect is improved.

As shown in FIG. 3, blender cup 12 includes a handle 122, handle 122 facilitating access to blender cup 12 by a user. In the orthographic projection of the height direction of the mixing cup 12, the projection area of the first shock absorption bulge 145 at least partially overlaps with the projection area of the handle 122. In this way, the shock absorbing effect at the handle 122 can be improved.
