Description

Food processor

Technical Field

The invention relates to the technical field of material treatment, in particular to a food processor.

Background

Along with the development of technology, stirring equipment is increasingly applied to daily life of people, such as dough kneaders, soymilk makers, juicers, wall breaking machines and the like. The stirring devices drive stirring blades or stirring paddles and the like through driving shafts to stir, and automatically cut and/or stir materials.

However, in order to ensure that the conventional stirring blade or stirring blade can be reliably connected to the drive shaft when the drive shaft rotates, the stirring blade or stirring blade is often fixed to the drive shaft so as not to be thrown out of the stirring apparatus. The existing stirring blade or stirring blade and the like are inconvenient to detach, and a great deal of time and energy are required for detaching; this results in the difficulty of cleaning the stirring blade or blade and the bottom of the stirring device after the user has used up the stirring device, which is one of the main pain points of the user.

Moreover, if the user directly stretches his hand into the stirring device with the stirring blade for cleaning, it is easy to cut the hand due to the sharp blade, which is also one of the main pain points of the user.

In addition, the stirring equipment mostly comprises a stirring cup and a base, wherein the output end of a power mechanism in the base is connected with the connecting end of a stirring assembly of the stirring container, and the power mechanism drives the stirring assembly to rotate so as to automatically cut and/or stir materials in the stirring container.

However, the output end of the existing power mechanism and the connecting end of the stirring assembly are both connected through the cooperation of the plurality of protrusions and the plurality of grooves, when the stirring cup is placed on the base, the plurality of protrusions and the plurality of grooves need to be accurately aligned, so that the position of the stirring cup needs to be continuously rotated to ensure that the plurality of protrusions can be inserted into the plurality of grooves, the installation is inconvenient, and even a long time is required to accurately place the stirring cup on the base, which is one of the main pain points of users. In addition, in the stirring process of the stirring equipment, the heating value of the joint of the protrusion and the groove is large, the requirement on the stirring time is high, the stirring time needs to be controlled in a short time, and even materials which are difficult to stir or cut up need to be paused in the middle for heat dissipation, and great inconvenience is brought to users because the joint of the protrusion and the groove is cooled and then stirred or cut continuously. Moreover, the connection between the protrusion and the recess is difficult to avoid having a gap, which results in loud noise and vibration during operation, which affects the user's feeling, which is one of the main pain points of the user.

Furthermore, in the description of the present invention, unless otherwise indicated, the meaning of "a plurality", "a plurality of groups" is two or more.

As shown in fig. 1 and 2, in one aspect, an embodiment of the present invention provides a bidirectional lock 2, which includes:

an outer ring 21, wherein a movable channel is formed in the inner wall of the outer ring 21;

the movable body comprises a first movable body 22 and a second movable body 23, wherein the first movable body 22 and the second movable body 23 are rotatably arranged in the movable channel, the first movable body 22 and the second movable body 23 are partially exposed out of the movable channel, the first movable body 22 and the second movable body 23 are respectively provided with a locking end and an unlocking end, the diameter of the first movable body 22 passing through the locking end is larger than the diameter of the first movable body 22 passing through the unlocking end, and the diameter of the second movable body 23 passing through the locking end is larger than the diameter of the second movable body 23 passing through the unlocking end; the direction in which the first movable body 22 is rotated from its unlock end toward the lock end is opposite to the direction in which the second movable body 23 is rotated from its unlock end toward the lock end, that is, the direction in which the first movable body 22 is rotated from its lock end toward the unlock end is opposite to the direction in which the second movable body 23 is rotated from its lock end toward the unlock end.

For example, the direction in which the first movable body 22 rotates from its unlock end toward the lock end is clockwise, and the direction in which the second movable body 23 rotates from its unlock end toward the lock end is counterclockwise; similarly, the first movable body 22 rotates from its locking end toward its unlocking end in a counterclockwise direction, and the second movable body 23 rotates from its locking end toward its unlocking end in a clockwise direction.

The bidirectional locking member 2 can conveniently realize bidirectional locking and can also conveniently be disengaged. Specifically, when the bidirectional locking member 2 is sleeved on the driving assembly to be assembled, the first movable body 22 and the second movable body 23 are both in contact with the driving assembly. The driving component can be a driving shaft 4, or can be a structural member of which at least one shaft sleeve is sleeved on the driving shaft 4, and when the driving component is the driving shaft 4, the first movable body 22 and the second movable body 23 are in direct contact with the driving shaft 4; when the driving shaft 4 is sleeved with the shaft sleeve, the first movable body 22 and the second movable body 23 are in direct contact with the shaft sleeve. The present invention will be described by taking a drive assembly as a drive shaft 4.

Further, as shown in fig. 1 and 2, the arrow direction in fig. 1 and 2 indicates the rotation direction of the drive shaft 4, the arrow indicated to the left indicates the counterclockwise rotation of the drive shaft 4, and the arrow indicated to the right indicates the clockwise rotation of the drive shaft 4.

Specifically, the driving shaft 4 is rotated clockwise to drive the first movable body 22 to rotate from the unlocking end to the locking end thereof, and at this time, the second movable body 23 rotates from the locking end to the unlocking end thereof, so that the first movable body 22 is clamped on the outer periphery of the driving shaft 4, and at this time, the outer ring 21 is locked on the driving shaft 4; or, the driving shaft 4 rotates anticlockwise to drive the second movable body 23 to rotate from the unlocking end to the locking end, at the moment, the first movable body 22 rotates from the locking end to the unlocking end, so that the second movable body 23 is clamped on the periphery of the driving shaft 4, at the moment, the outer ring 21 is still locked on the driving shaft 4, bidirectional locking of the bidirectional locking piece 2 and the driving shaft 4 is realized, and forward and reverse synchronous rotation of the bidirectional locking piece 2 and the driving shaft 4 is ensured; when the outer race 21 externally fixes the rotating member, the rotating member can rotate in synchronization with the driving shaft 4 in the forward and reverse directions.

When the bidirectional locking member 2 needs to be disengaged from the driving assembly, it is only necessary to reversely rotate the outer race 21 by a slight angle, for example, about 10 degrees, so that the first movable body 22 is unlocked or the second movable body 23 is unlocked to unlock the driving assembly. Here, when the first movable body 22 is unlocked, the second movable body 23 moves from the unlock end toward the lock end, but is unlocked, and similarly, when the second movable body 23 is unlocked, the first movable body 22 moves from the unlock end toward the lock end, but is unlocked; that is, the first movable body 22 and the second movable body 23 are both in the unlocked state. At this time, only a small force needs to be applied to pull the bidirectional locking piece 2 out of the driving assembly such as the driving shaft 4, so that the bidirectional locking piece and the driving shaft are separated; for the condition of the outer fixed rotating part of the outer ring 21, the rotating part and the bidirectional locking piece 2 are conveniently detached together as a whole, and the rotating part is conveniently cleaned.
