Description

Technical Field

[0001] The invention relates to a kitchen appliance, in particular to a strong stirring device. Background Art

[0002] A powerful stirring device generally has a variety of accessories such as a juice cup, an egg beater, and a blender. The accessories are generally installed between the head and the base of the machine body. When replacing the accessories, the head needs to be lifted up, and when working, the head needs to be lowered and locked. The powerful stirring device in the prior art basically uses a knob to turn the head up. The head is heavy because of the electric components installed on the head, so the lifting operation relying on the knob to turn is relatively laborious. Summary of the invention

[0022] For the purpose of explanation, the width, length and thickness of some components in the schematic diagram are sometimes exaggerated.

[0023] like Figures 1 to 6 As shown, a powerful stirring device comprises a head 1, a body 2 and a head-raising structure for rotating and raising the head relative to the body. The head-raising structure further comprises a head-raising rod 6, a lever 9 and a first elastic component arranged on the body, and a head bottom cover 8 and a second elastic component arranged on the head. The lever 9 and the head-raising rod 6 are fixedly connected, or the lever 9 and the head-raising rod 6 are integrally formed, and the lever 9 can rotate relative to the body 1 under the action of the head-raising rod 6; in the working state, the lever 9 buckles the head bottom cover 8. When the head needs to be raised, the head-raising rod is pulled, driving the lever to rotate, the lever 9 is separated from the head bottom cover 8, and the head 1 rotates under the action of the second elastic component to achieve head raising; when the head 1 needs to be returned to its original position, the head 1 is pressed down, and the lever 9 buckles the head bottom cover 8 under the action of the first elastic component to achieve the return of the head 1.

[0024] The first elastic component is used to give the lever 9 an elastic force to engage with the head bottom cover 8. In some embodiments, the first elastic component includes a lever shaft 5 and a lever torsion spring 3 sleeved on the lever shaft, one end of the lever torsion spring 3 presses against the inner wall of the body, and the other end presses against the lever 9. The lever shaft 5 is fixed to the body 2 by means of screws.

[0025] The second elastic component is used to give the handpiece an elastic force to rotate upward. In some embodiments, the second elastic component includes a rotating shaft 7 and a rotating shaft torsion spring 4 sleeved on the rotating shaft. The rotating shaft 7 gives the handpiece an elastic force to rotate upward under the action of the rotating shaft torsion spring 4.

[0026] like Figure 1 to Figure 5 As shown, a powerful stirring device comprises a machine head 1, a machine body 2 and a lifting structure, and the machine head 1 can be lifted relative to the machine body 2 by means of the lifting structure. The lifting structure further comprises a lifting rod 6, a lever 9, a lever shaft 5, a lever torsion spring 3, a machine head bottom cover 8, a shaft 7 and a shaft torsion spring 4. The lever shaft 5 is set on the machine body 2 by screws, and the lifting rod 6 is fixed to the lever 9 and can rotate around the lever shaft 5. One end of the lever torsion spring 3 presses against the inner wall of the machine body 2, and the other end always applies a certain spring torsion force to the lever 9, so that when the machine head 1 is pressed to the bottom, the lever 9 can hook the machine head bottom cover 8. In addition, the lever torsion spring 3 always applies a certain spring torsion force to the lever 9, and when the machine head bottom cover 8 is lifted upward by the shaft 7 so that the machine head 1 is lifted to the maximum position, the free end of the lever 9 can ensure that it presses against the machine head bottom cover 8 without being separated from it, so that the lever 9 can play an effective role when the machine head 1 is pressed back to its original position.

[0027] The lower part of the head bottom cover 8 is provided with a convex strip 81, which can withstand the large impact force when processing food, such as when stirring noodles. In some embodiments, the convex strip 81 is arc-shaped.

[0028] In some embodiments, a hook 22 is provided at the free end of the lever 9, and an upper buckle groove 82 adapted to the hook 22 is provided above the convex strip 81 of the machine head bottom cover 8. In other embodiments, a lower buckle groove 83 adapted to the hook 22 is further provided below the convex strip 81 of the machine head bottom cover 8. The lever 9 is provided with a long strip groove 21, and when the hook 22 of the lever 9 is engaged with the upper buckle groove 82, the convex strip 81 is embedded in the long strip groove 21. The cross section of the groove 21 is square, and the cross section of the convex strip is also square.

[0029] The working process of the head-up structure of the powerful stirring device is as follows:

[0030] like Figure 4 and Figure 5As shown, the user moves the head-raising lever 6, and the head-raising lever 6 drives the lever 9, and the lever 9 rotates counterclockwise, and the hook 22 of the lever 9 disengages from the upper buckle groove 82 of the machine head bottom cover 8. At this time, the machine head bottom cover 8 and the machine head 1 rotate clockwise under the torsion of the rotating shaft torsion spring 4 to achieve head-raising. When the head-raising is in place, the hook 22 of the lever 9 is buckled into the lower buckle groove 83 of the machine head bottom cover 8.

[0031] On the contrary, when the machine head needs to be returned to its original position, the user pushes the lifting rod 6, the hook 22 of the lever 9 disengages from the lower buckle groove 83 of the machine head bottom cover 8, and then presses the machine head, the machine head bottom cover 8 and the machine head 1 rotate counterclockwise together, and when the machine head bottom cover 8 turns to its buckle groove 81 and reaches the hook 22 of the lever 9, the hook 22 of the lever 9 is rotated clockwise by the torque of the lever torsion spring 3 and buckles the upper buckle groove 82 of the machine head bottom cover 8, thereby realizing the return of the machine head 1.

[0032] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and these modifications and replacements should all fall within the scope of protection of the claims attached to the present invention.
