Description

Technical Field

[0001] The utility model relates to the technical field of juicers, and more particularly to a juicer with multiple safety protection mechanisms. Background Art

[0002] A juicer is a type of blender, which is mainly used to blend ingredients. The basic structure of a juicer is a main unit and a blending cup installed on the main unit. A juicer component is arranged in the blending cup, and the juicer component may be a blending knife, a juicer plate, a filter, etc. When the juicer component rotates at a high speed, it can squeeze juice and chop ingredients.

[0003] In order to ensure the safety of use, a protective mechanism is provided between the main body and the blending cup of the juicer in the prior art, and the protective mechanism includes: a micro switch provided on the main body, a slide bar provided on the cup body, and a trigger bar provided on the cup cover. When the cup cover is correctly installed on the cup body, the trigger bar pushes the slide bar downward, thereby triggering the micro switch to close, and the juicer is powered on and runs after being powered on, effectively preventing the juice extraction component from rotating at a high speed and injuring the user when the cup cover is not installed. In this prior art, the micro switch is disconnected when the cup cover is taken out, and the juice extraction component has not stopped when the cup cover is taken out because the juice extraction component rotates at a relatively high speed, which poses a safety hazard.

[0004] There is another protection mechanism for a juicer in the prior art. For example, Chinese patent number: CN202122619275.1 discloses a centrifugal juicer, in which a safety switch linkage device is provided between the lid and the base. The safety switch linkage device includes a microswitch and a pull rod. When the rod slides and presses the card block, the microswitch turns on the circuit, and the juicer as a whole can start working. When the pull rod does not press the card block, the microswitch is disconnected, and the juicer as a whole cannot work. This prior art triggers the microswitch by rotating the pull rod, but this prior art still has hidden dangers. Even if the lid is not installed on the body, the microswitch can still be triggered when the pull rod is rotated to the specified position. Then, it can still work when the lid is not installed, which poses a serious safety hazard.

[0005] In order to solve the above problems, the applicant has improved the existing technology and proposed the following technical solutions. Utility Model Content

[0074] The host 100 is provided with a lever mechanism 400, which includes a lever 410 and a rotating assembly 420. Both ends of the lever 410 are connected to the host 100. When the lever 410 rotates, it can drive the rotating assembly 420 to rotate. The lever 410 can rotate to a first position and a second position. Figure 4 As shown, when the pressing rod 410 rotates to the first position, the pressing rod 410 is located at the top of the collection cup 200 and pressed against the top cover 300, and the first micro switch assembly 110 is triggered to close by the rotating assembly 420; Figure 3 As shown, when the pressing rod 410 rotates to the second position, the pressing rod 410 leaves the top of the collecting cup 200, and the first micro switch assembly 110 is disconnected;

[0075] A sliding mechanism 500 is provided between the host 100 and the collection cup 200 , and the sliding mechanism 500 includes: a sliding rod 510 installed on the collection cup 200 and a sliding assembly 520 installed on the host 100 ;

[0076] The top cover 300 is provided with a trigger rod 310. When the top cover 300 is installed on the collection cup 200, the trigger rod 310 pushes the slide bar 510 to move downward, and the slide bar 510 pushes the sliding assembly 520 to trigger the second micro switch assembly 120 to close.

[0077] When the first micro switch assembly 110 and the second micro switch assembly 120 are both triggered to close, the circuit is connected;

[0078] When either the first micro switch assembly 110 or the second micro switch assembly 120 is disconnected, the circuit is disconnected;

After the top cover 300 is installed, the trigger rod 310 pushes the slide bar 510 downward, and the slide bar 510 pushes the slide assembly 520 to trigger the second micro switch assembly 120 to close. When the second micro switch assembly 120 is closed, the power assembly is not running;

[0084] Then the pressure rod 410 is rotated from the second position to the first position, and the first micro switch assembly 110 is triggered to close by the rotating assembly 420, then the second micro switch assembly 120 and the first micro switch assembly 110 are closed, and the power assembly is powered on to drive the juice extraction assembly 210 to perform the juice extraction action.
