Firstly, it is necessary to make clear the structural difference between the cup body and the cup lid, the cup body is a container with a certain volume, the depth dimension (or height dimension) is larger, and the cup lid is basically a flat structure, although having a certain depth, it is shallower than the cup body, secondly, the cross-sectional area of the upper cavity 201 becomes smaller from bottom to top, that is, the cross-sectional area of the bottom end of the upper cavity is inevitably larger than that of the top end, there may be a part with unchanged size in the middle, and that of the lower cavity 202 becomes smaller from top to bottom.
The utility model discloses an it replaces current crushing bowl cover to go up cup 21, utilize cup 21 and lower cup 22 to connect and form crushing chamber 200, compared with the prior art, under the condition of the crushing chamber 200 that forms same volume, the height and the volume of cavity of resorption 202 have all diminished, the height and the volume of epicoele 201 increase, simultaneously because the cross-sectional area of epicoele 201 is by supreme trend that diminishes that is down, the thick liquid meets with edible material behind the inside wall of epicoele 201, will be rebounded back to falling in cavity of resorption 202, thereby shorten thick liquid and eat the distance that the inside wall climbing wall of epicoele 201 was followed to the material, in the same crushing time, eat the number of times of material and crushing sword 3 contacts and increase, consequently, can improve crushing efficiency. After the slurry is rebounded to the lower cavity 202, the working liquid level of the slurry is pressed downwards to be lower, the slurry and the food materials are not easy to contact the top of the upper cup body 21, the area of the inner wall of the upper cavity 201 polluted by the slurry is smaller, and the slurry is easier to clean in the subsequent automatic cleaning process. And because the working liquid level is low, the vortex formed by the centrifugal motion of the slurry is reduced, and the noise generated along with the vortex is also reduced. In prior art, smash and generally be equipped with ventilative bleeder vent on the bowl cover, the utility model discloses also set up bleeder vent 211 on the top of last cup 21, and smash the sound that the rotatory cutting of sword 3 was eaten the material, the sound of eating the material striking crushing chamber 200 inner wall generally all can upwards propagate and spread through the bleeder vent, because the cross-sectional area of epicoele 201 is by supreme diminishing trend that is down, the sound propagation can meet the hindrance of last cup 21 and energy loss appears, consequently can reach the noise reduction of certain degree. The cross-sectional area of the lower cavity 202 tends to decrease from top to bottom, so that the slurry and the food materials can climb up in time to climb the wall under the influence of centrifugal motion, the circulation of the food materials is promoted, and the crushing effect is improved.
For convenient processing, the upper cup body 21 can adopt a revolving body structure, the inner side wall of the upper cavity 201 comprises a first revolving surface 203 formed by revolving a first curve, the first revolving surface 203 is positioned at the bottom of the inner side wall of the upper cavity 201, and the inner diameter of the first revolving surface 203 is reduced from bottom to top, so that the distance of wall climbing of the inner side wall of the upper cavity 201 for slurry and food materials can be shortened, and the slurry and the food materials can stably and smoothly fall back into the lower cavity 202.
As a structure which is easier to realize, the first curve can be selected to be a straight line, and in order to form the first surface of revolution 203 which can let the slurry and the food fall back to the lower cavity 202, as shown in fig. 2, the straight line has an angle α with the end surface of the mouth of the upper cup 21, where α is 30 °, 45 °, 60 °, 75 ° or 89 °, and so on, and α is 81 ° in this embodiment.
In the same way, the lower cup 22 may also be a revolving structure, the inner side wall of the lower cavity 202 includes a second revolving surface 204 formed by revolving a second curve, the second revolving surface 204 is located at the top end of the inner side wall of the lower cavity 202, and the inner diameter of the second revolving surface 204 is reduced from top to bottom, so that the slurry can be guided to climb the wall to form a circular flow, all food materials can uniformly contact the crushing blades 3, and the crushing effect is improved.
The food material is centrifugally moved due to the rotation of the crushing blades 3, so when the food material moves in the lower cavity 202, the food material is rebounded due to the impact on the inner wall of the lower cavity 202, in order to enable the rebounded food material to move towards the crushing blades 3, a second curve can be selected as a second parabola, the focus of the second parabola is located on the extension line of the output shaft 41 of the crushing motor 4, referring to fig. 3, the focus of the second parabola is higher than the mouth end face of the lower cup 22, the height difference is H6, H6 is greater than 0 and less than or equal to 40mm, the integral rebounding trend of the food material is ensured to be upward and pass through the rotating area of the crushing blades 3, the contact probability of the food material and the crushing blades 3 is improved, and the crushing efficiency is further promoted to be improved.

The height of the crushing cavity 200 is H3, so that in order to avoid the position of the cutter body 31 from being too low or too high, H3/H2 can be limited to 2-100. H3/H2 is too small, the position of the cutter body 31 is too high, and is too far away from the inner bottom surface of the lower cavity 202, and the material is easily deposited below the crushing cutter 3 due to the self-weight, and the crushing efficiency is reduced, whereas H3/H2 is too large, the position of the cutter body 31 is too low compared with the height of the crushing cavity 200, and the cleaning effect is reduced because the crushing cutter 3 drives the cleaning water to hardly reach the inner top surface of the upper cavity 201 in the cleaning stage.
The height relationship between the fixing position of the cutter body 31 and the lower cavity 202 and the height relationship between the fixing position of the cutter body and the crushing cavity 200 are limited, H3/H1 can be designed to be 2-10 in order to control the height relationship between the lower cavity 202 and the crushing cavity 200, and the height of the lower cavity 202 is small overall, so that the upper blade 32 can be ensured to better act on the upper cavity 201.

Generally, the volume of the upper chamber 201 is larger than that of the lower chamber 202, and the slurry can flow in a circular manner and can enter the upper chamber 201 more easily, so that the first surface of revolution 203 can function better.
Example two:
referring to the design that the second revolution surface 204 adopts a second parabola, the first curve can also be selected as a first parabola, the focus of the first parabola is located on the output shaft 41 of the grinding motor 4 and is lower than the cutter body 31, as shown in fig. 5, the height difference between the focus of the first parabola and the cutter body 31 is H5, H5 is more than 0 and less than or equal to 20mm, and by utilizing the focusing characteristic of the first parabola, when the slurry and the food material impact the first revolution surface 203, the slurry and the food material can rebound to the area where the focus of the first parabola is located, and the food material can pass through the rotating area of the grinding cutter 3, namely the direction indicated by the arrow in fig. 5, so that the frequency of the food material contacting the grinding cutter 3 is increased, and the grinding efficiency is greatly improved.
