Referring to fig. 1, the present application discloses a cup locking assembly 10, a food processor host and a food processor 100. The lock cup assembly 10 is assembled to the food processor base 20 in the embodiment of the present application to constitute a food processor main body with the food processor base 20. The food processor 100 further comprises a food processing cup assembly 30. The lock cup assemblies 10 are used for locking the food processing cup assemblies 30, the number of the lock cup assemblies is not limited, the purpose of locking can be achieved, and two lock cup assemblies 10 are illustrated in fig. 1. The lock cup assembly 10 of the present application can be applied to a food processor having a kneading and/or stirring function and the like requiring a large torque.

Referring to fig. 2 and 3 in conjunction with fig. 5, 6, 7, 8 and 9, a lock cup assembly 10 includes a support member 1, a pushing member 2, an elastic member 3, a driving member 4 and a motor 5. The support 1 serves at least as a mounting carrier for the pushing member 2 (and in the present embodiment, also as a mounting carrier for the elastic member 3), and its structure is not limited. In the embodiment of the present application, the support 1 includes a bracket 11 and a bracket cover 12, the bracket 11 and the bracket cover 12 cover to form a through cavity, and the pushing member 2 is disposed through the through cavity. The pushing member 2 is assembled to the support member 1 and can be extended or retracted (or retracted) with respect to the support member 1. The purpose of extending is to lock the food cup assembly 30, and the purpose of retracting is to unlock the food cup assembly 30, so that the structure of extending or retracting is not limited. The elastic part 3 is abutted against the pushing part 2 and the supporting part 1. The elastic member 3 is deformed in this application to provide an elastic force to the pushing member 2, so that the pushing member 2 can extend or retract, and the purpose can be achieved. The driving member 4 includes a cam in the present embodiment, and the structure of the cam is not limited as a component for driving the pushing member 2 to extend or retract. A motor 5 is connected to the cam to drive it in rotation. How the motor 5 is connected to the cam is not limited.

Please refer to fig. 6, fig. 7, fig. 8, fig. 9 in combination with fig. 5. Fig. 6 and 7 illustrate the state in which the pusher 2 is retracted (which may also be referred to as retracted) relative to the support 1 (also referred to as the initial state of the pusher 2, corresponding to the initial state of the locking cup assembly 30), which is relative to extension, and not specifically to the retraction of the pusher 2 into the support 1 (although in some embodiments it may be retracted into the support, for example, with the end of the pusher 2 aligned with the corresponding end of the support 1). Fig. 8 and 9 illustrate the state in which the pusher 2 is extended with respect to the support 1 (corresponding to the locked state of the cooking cup assembly). In the case where the motor 5 drives the cam to rotate in the first direction, the first direction rotation causes, for example, the cam to rotate counterclockwise in the drawing direction of fig. 6 as indicated by a broken-line arrow R1. And as shown in connection with fig. 5, the motor 5 drives the cam in rotation, whereby said cam pushes said pusher 2 to extend with respect to said support 1, the movement state of the pusher 2 being changed from the initial state shown in fig. 6 to the intermediate state shown in fig. 5 to the final state shown in fig. 8. During the extension of the pushing member 2, the elastic member 3 is compressed, and in the present embodiment, the elastic member 3 is compressed by the pushing member 2. In the case where the motor 5 drives the cam to rotate in a second direction opposite to the first direction, the pushing member 2 is retracted relative to the supporting member 1 by the resilient force of the elastic member 3, specifically, from the final state shown in fig. 8 to the initial state shown in fig. 6. The second direction is, for example, clockwise, as indicated by the dashed arrow R2 of fig. 8. The rotation of the cam in the first direction or the second direction may be achieved by applying a forward voltage or a reverse voltage to the motor 5 so that the motor rotates in the forward direction or the reverse direction. The skilled person will understand that the stroke of the pushing element 2 can be selected according to the actual product, in this embodiment, referring to fig. 6 and 8, the stroke of the pushing element 2 corresponds to the difference between the distances between the different edges of the cam and the center of rotation, i.e. the stroke is L2-L1, and in various embodiments of the present application, the difference between L2-L1 is 4-10 mm.

Secondly, by the effect of the cam, the rotary motion is converted into the linear motion, so that the pushing part 2 moves along the linear motion, and therefore, the stroke control precision of the cup locking assembly 10 is high, and finally, in the cup locking state, the pushing part 2 is always matched with the related structure (such as a clamping groove) of the food processing cup assembly 30 through the cam, and therefore the locking force is large.

The process of locking or unlocking the lock cup assembly shown in fig. 14 is described in more detail as follows:

in this embodiment, the motor shaft of the motor 5 comprises a gear 51 and the drive 4 comprises a screw 47. In the event that the food cup assembly 30 needs to be locked (lock cup), the motor shaft engages the screw 47. Motor 5 drives screw to move linearly in a first direction, shown in fig. 14, in direction a1 until pusher member 2 moves with screw 47 to a maximum stroke, i.e. screw 47 moves to a maximum stroke, and then pusher member 2 moves to a maximum stroke (i.e. extends with linear movement of the screw with respect to support member 1 to a maximum stroke). Under the condition that the pushing piece 2 moves to the maximum stroke, the pushing piece 2 is inserted into the clamping groove 301 of the cooking cup assembly 30, so that the cooking cup assembly 30 is locked.

So set up, except having some beneficial effects that aforementioned lock cup subassembly adopted the cam, can also avoid the problem that the motor reversal leads to, improve the motor life-span.

In the case where the drive 4 comprises a threaded rod, the pusher 2 may also comprise an abutment wall facing said drive 4 and curved, in contact with the curved face of the tip of the threaded rod in the case of its movement to the maximum travel. See the foregoing.

In the case where the lock-cup assembly comprises a threaded rod 47, the pusher 2 and the driver 4 may also be provided with a stop structure to limit the positional relationship between the pusher 2 and the threaded rod 47, which in a further embodiment comprises a groove provided in the pusher and facing the driver, into which groove the threaded rod is inserted during the rectilinear movement, such groove having a shape matching the shape of the end of the threaded rod 47.

In some embodiments, the supporting member 1 is integrally formed with the food processor base 20, and in other embodiments, the motor 5 is directly connected to the driving member 4, as described above, the motor shaft of the motor 5 is directly connected to the cam, and the motor shaft (including the gear 51) of the motor 5 is directly connected to the screw.
