As a preferred embodiment of the present application, as shown in fig. 3, the food processor is further provided with a shaft seal 8 sealingly engaged with the rotary shaft 31 and a spring 9 abutting under the shaft seal 8, the spacer 5 is provided with a positioning cavity for positioning the shaft seal 8 and the spring 9, specifically, as shown in fig. 3, a positioning ring rib 56 extending upward is provided at the shaft hole 54, and the positioning cavity is formed in the positioning ring rib 56.

Through be equipped with the location bearing seal 8 and the location chamber of spring 9 at the spacer 5 for bearing seal 8 and spring 9 realize the stability of fixed position through the location of location chamber, avoid bearing seal 8 and spring 9 to take place great displacement and lead to its sealed condition of inefficacy. Meanwhile, the spacer 5 can also provide positioning for the shaft seal 8 and the spring 9 while realizing the isolation between the cup body 2 and the motor 3, so that the functional effect of the spacer is improved, the situation that the positioning structure is arranged on the cup body 2 to position the spacer is omitted, the spacer 5 is convenient to produce, and the production cost is reduced.

The technical solution protected by the present utility model is not limited to the above embodiments, and it should be noted that, the combination of the technical solution of any one embodiment with the technical solution of the other embodiment or embodiments is within the scope of the present utility model. While the utility model has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the utility model and are intended to be within the scope of the utility model as claimed.
