Description

Technical Field

[0001] The invention relates to a lifting food processor and a use control method thereof. Background Art

[0002] With the development of society, people's pursuit of quality of life is constantly improving. More people choose to cook their own food, and food processors are widely popular in the market. While food processors provide people with a convenient cooking method, they also have some problems.

[0003] The cup body of the food processor on the market is equipped with a knife group inside, and a coupler connected to the knife group is provided at the bottom of the cup body. A clutch that cooperates with the coupler is correspondingly provided on the base, and the clutch is connected to the drive motor inside the base; when in use, only when the coupler at the bottom of the food processor cup body is correctly aligned and engaged with the clutch, can the power of the drive motor be smoothly transmitted to the knife group inside the cup body. However, when taking and placing the food processor cup body, people need to manually lift the cup body, and then move the cup body parallel to the outside of the food processor base. The step of taking and placing the cup body requires people to move in both vertical and horizontal directions, and there are many movements. Moreover, since the coupler is fixed at the bottom of the food processor cup, people cannot see the coupler when placing the food processor cup, which can easily cause the coupler and the clutch to be inaccurately docked. When the coupler and the clutch are offset multiple times during docking and engagement, the wear of the coupler will be increased and the service life of the coupler will be reduced. At the same time, when the food is added to the cup body, it is often heavy, and the user will have many inconveniences in taking and placing the cup body.

[0004] The Chinese patent number CN201720061087.2 discloses a food processor with a lifting function. In the food processor of this structure, the cup cover is fixed to the machine base, and the inner cavity of the cup body is sealed and isolated by the liftable cup body, which effectively simplifies the structure between the cup cover and the machine base, and provides users with a novel opening and closing method to improve the user experience. However, when the cup body is working, the whole body is sealed with the cover body after rising through the lifting seat, and the working position of the food processor is in the position after the lifting mechanism rises to the bottom; however, during the food cooking process of the food processor, the blade in the cup body needs to rotate at high speed, the cup body is easy to shake, and the weight of the cup body and food is all pressed on the lifting seat and the lifting mechanism. When working, stability is difficult to guarantee. Summary of the invention

[0027] Figure 4 It is a three-dimensional exploded view of the lifting food processor in the embodiment of the present invention. DETAILED DESCRIPTION

[0028] The present invention is further described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 4 The lifting food processor shown comprises a base 1 and a food cup 2 arranged on the base, the top of the food cup 2 has an opening, and a cup cover 3 is sealed at the opening of the food cup 2. The base is provided with a cup body fixing seat 4, and the cup body fixing seat 4 is provided with a locking mechanism that can cooperate with the outer wall of the food cup or the cup cover to limit the food cup, and the base is provided with an automatic lifting mechanism that can drive the cup body fixing seat to rise or fall, and a control board electrically connected to the automatic lifting mechanism. In the drawings, the control board is hidden inside the base and is not shown.

[0030] In this embodiment, the cup body fixing seat 4 includes a left side wall 41, a rear side wall 42 and a right side wall 43. When the left side wall 41, the rear side wall 42 and the right side wall 43 are connected in sequence, the entire cup body fixing seat is a "U"-shaped structure after being rotated 90 degrees. The left side wall 41 and the right side wall 43 are symmetrically arranged, and an opening is formed between the left side wall 41 and the right side wall 43. The left side wall 41, the rear side wall 42 and the right side wall 43 are integrally formed, and the locking mechanism is a locking groove 44 arranged on the inner side of the left side wall 41 and the right side wall 43. The locking groove 44 can be directly locked with the outer wall of the cooking cup 2, and symmetrical lugs can be arranged on the outer wall of the cooking cup 2. In this embodiment, the locking groove 44 is used to lock the cup cover 3; the locking groove 44 extends horizontally backward from the opening of the left side wall 41 and the right side wall 43 to form a guide mechanism for guiding the cooking cup to enter the locking mechanism. The cup body fixing seat 4 can form an embracing protective structure for the cooking cup, which can improve the stability of the cooking cup when it is in working state and prevent the cooking cup from shaking due to the high-speed rotation of the knife group. At the same time, it can also effectively reduce the noise of the whole machine. When the user takes and puts the cooking cup, there is only one "horizontal insertion" action, which greatly facilitates the user's operation. At the same time, due to the existence of the card slot, when the user takes and puts the cooking cup, there is the support of the card slot, which is not only accurate in direction, but also has a supporting force on the cooking cup, reducing the user's holding force of the cooking cup, which is very helpful when the cooking cup contains more and heavier food.
