The difference between this embodiment and the first embodiment is that in this embodiment, the upper casing 11 is a barrel-shaped structure that penetrates up and down and is closed in the circumferential direction, and a sealing ring is arranged between the upper casing 11 and the lower casing 12 13, to seal the gap between the upper casing 11 and the lower casing 12. At the same time, the cleaning liquid sprayed from the upper nozzle 41 is sprayed obliquely toward the top wall of the cover body.

For this embodiment, the vertical maximum distance between the upper spout and the inner surface of the top wall of the cover is H, where H=4mm~29mm is required, because if H is less than 4mm, the spray from the upper spout to the top wall of the cover is H. The cleaning water may bounce directly to the bottom of the container because the impact speed is too large, so that it will not wash along the top wall of the cover to the edge of the top wall of the cover, and lose the function of flushing the edge of the top wall of the cover and part of the peripheral wall of the cover. Complete cleaning of the cover is achieved. Similarly, if H is greater than 29mm, not only the overall height of the cover body is larger, but also the cleaning water sprayed from the upper nozzle needs a larger impact force to reach the top wall of the cover body, which not only increases the performance requirements of the water supply system , increase the design cost, and the cover itself will appear too bloated and affect the appearance. For this embodiment, the overall height of the cover body is preferably 6 mm˜30 mm, and H is preferably 5 mm˜25 mm.

At the same time, for this embodiment, the cleaning water sprayed from the upper nozzle is inclined to the top wall of the cover body relative to the vertical plane, which is more conducive to the cleaning water hitting the top wall of the cover body. The inertia component of scouring enables the cleaning water to spread out and wash to the edge of the top wall of the cover body and flow down along the peripheral wall of the cover body. Among them, the required injection inclination α≤15º. In the structure of this embodiment, if α is greater than 15°, the sprayed cleaning water may not be able to clean the top wall of the cover body, or may not completely clean the top wall of the cover body, resulting in the possibility of unclean cleaning. Therefore, for this embodiment, the injection inclination angle α is preferably 5º~12º.

It should be noted that the above-mentioned structural changes of this embodiment can also be applied to other embodiments of the present invention.

At the same time, for this embodiment, the nozzle can also only be provided with a through hole on the upper casing. In this case, the outlet end of the through hole needs to be inclined toward the cover body, so as to spray cleaning water toward the cover body to wash the cover body. Moreover, the wall of the upper casing may be provided with a plurality of through-holes sprayed toward the cover, for example, a circle may be arranged around the circumference of the upper casing, so as to achieve flushing and cleaning of the top wall of the entire cover. It should be noted that the above-mentioned structural changes of this embodiment can also be applied to other embodiments of the present invention.

Embodiment 4:

As shown in FIG. 6 and FIG. 7 , it is a schematic structural diagram of a fourth embodiment of the present invention. The present embodiment is a food processing machine with a motor below, including a body 7 and a cup body 8 arranged in the body 7, and the motor shaft of the motor (not marked in the figure) penetrates the bottom of the cup body 8 and extends into the cup body 8, and a crushing blade is installed at the end of the motor shaft.

In this embodiment, the body 7 has a transition portion 71 extending to the top of the cup body 8 and sealingly connected to the top of the cup body 8 . The transition portion 71 is barrel-shaped and formed as an upper shell, and the cup body 8 is a lower shell. The transition part 71 and the cup body 8 are enclosed to form a cavity of the container, the nozzle 4 is arranged on the side wall of the transition part 71 , and the cover body 2 covers the top of the transition part 71 . A sealing sleeve 9 sleeved on the outside of the nozzle 4 is provided between the nozzle 4 and the transition portion 71 , and the sealing sleeve 9 can seal the gap between the nozzle 4 and the transition portion 71 to prevent leakage. At the same time, the bottom of the cup body 8 has a pulverizing cavity 80 that shrinks inward, and a slurry outlet 81 is provided on the side wall or bottom wall of the pulverizing cavity 80, which is located outside the cup body 8, and the slurry outlet 81 is connected to the nozzle 4. It communicates through the circulation line 82 , and the circulation line 82 is provided with a control valve 83 for controlling the on-off of the circulation line 82 .

In addition, in this embodiment, the cup body 8 is a glass cup body, and the cover body 2 is also a transparent glass cover body, a vent hole 20 is provided in the center of the glass cover body, and a soft plug 21 is installed at the vent hole 20 . Meanwhile, the upper spout 41 is provided with a dust cover 42 that can open and close the upper spout 41 .

In this embodiment, one end of the dust cover can be hinged to the upper spout, and the other end can be turned over and opened relative to the upper spout. At the same time, the dust cover can also be a silicone piece fixed at the upper spout, and the central area of the dust cover is provided with a water outlet that can be opened and closed. Since the dust cover is a silicone piece, the water outlet has elasticity, when When there is cleaning water in the nozzle, under the action of the cleaning water pressure, the outlet seam opens and sprays the cover to clean and scour. Dust-proof and slag-proof of the upper spout.

For this embodiment, the outside of the cup body is provided with a circulation pipeline that connects the nozzle with the pulp outlet at the bottom of the cup body, and since the bottom of the cup body shrinks to form a crushing cavity, during cleaning, when the crushing blade rotates at a high speed, It will push the cleaning water to be sprayed out from the upper nozzle of the nozzle through the circulating pipeline to flush the cover body. The inner surface of the crusher is washed to form a water curtain effect for cleaning. The food processor of this embodiment can use the rotating power of its own crushing blade to perform cyclic cleaning, and the amount of cleaning water is less, which effectively reduces the waste of water resources. Of course, in order to ensure that the slurry will not be ejected through the nozzle during the pulping process of the food processor, a control valve will be set on the circulation pipeline to close the circulation pipeline. The control valve in this embodiment can be a three-way valve, and the three-way valve can also be connected to the water tank, so that the food processor can communicate with the nozzle through the water tank during the pulping process, so as to feed water into the cup.

In this embodiment, the transition part is a part of the body, and the cup body is a glass cup body. Due to the material characteristics of the glass cup body, the nozzle is arranged on the glass cup body, which is easy to avoid the possibility of the glass body being scrapped or damaged. If the nozzle is arranged on the transition part of the body, there is no such problem, which effectively solves the problem of nozzle installation and realizes automatic cleaning of the entire food processing machine. It should be noted that, in this embodiment, the vertical height H1 of the transition portion is not greater than 50mm, because if the transition portion is too high, the height of the corresponding glass body will be reduced, which is not conducive for consumers to observe food processing through the glass Therefore, the transition part generally only needs to be able to install the nozzle. For this embodiment, the transition part is 5mm~20mm. In addition, in this embodiment, the ventilation holes on the cover body can also have the function of feeding into the cup in addition to the function of making pulp and ventilation. It should be noted that the above-mentioned structural changes in this embodiment can also be applied to other embodiments of the present invention.
