Description

Technical Field

[0001] This invention relates to a cooking device with a lid locking mechanism. Background Technology

[0002] With the continuous improvement of people's living standards, many different types of cooking equipment have appeared on the market. The functions of cooking equipment mainly include, but are not limited to, making soy milk, juicing, rice paste, mincing meat, shaved ice, making coffee, and / or preparing face masks. Cooking equipment can include food processors, soy milk makers, blenders, or high-speed blenders—machines that grind and mix ingredients. However, most of the lids on existing cooking equipment lack a locking mechanism, posing a risk of the lid coming off if used carelessly. This can easily lead to accidents and safety hazards if users are not careful during operation.

[0003] Some cooking devices also have a locking pressure plate, which can lock the cup body and lid. The locking pressure plate can be either manually operated or electrically operated. Manual operation often requires manually rotating the locking pressure plate, which is complex and prone to wear. Another type uses a motor to rotate the locking pressure plate, but this can cause displacement of the cup body and lid, leading to wear on the coupling components at the bottom of the cup. Some food processors, such as the food processor cup disclosed in Chinese Patent No. ZL 201822206562.8, have a top cover at the top of the cup body, and a second lifting mechanism on the base. The top of this mechanism is fixedly connected to a pressure arm that presses the top cover against the opening of the food processor cup. This pressure arm can rise or fall under the drive of the second lifting mechanism. This structure, which uses a lifting and lowering arm to press the top cover, can largely prevent the cup from shifting laterally during the pressing process, thus ensuring the lifespan of the bottom connector. However, the presence of the pressure arm occupies space above the cup, making it prone to collisions, especially when placing or removing the cup, causing inconvenience. Furthermore, these structures require a motor, resulting in higher implementation costs. Some designs use a single electric push rod and linkage structure to drive the locking block to hold the lid in place; this requires high precision in the linkage. Others use two electric push rods to drive the locking blocks on the left and right sides respectively, but this requires high synchronization between the two electric push rods. If there is a large error between the two electric push rods, one side of the lid may be pressed down prematurely while the other side lifts up before being pressed down, potentially causing the lid's sealing ring to twist and leak. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a cooking device with a lid locking mechanism in light of the above-mentioned prior art. This automatic lid locking mechanism can not only automatically lock the lid and the body assembly, but also prevent the body assembly from shifting laterally during the locking or releasing of the lid.

The second end of the first lock can also rotate to the side of the pot lid under the drive of the electric push rod and the first linkage rod, thereby releasing the locking of the pot lid.

[0021] The fourth hydraulic cylinder is also equipped with hydraulic oil, and the fourth hydraulic cylinder is connected to the third hydraulic cylinder through a second hydraulic pipe.

[0022] The fourth hydraulic rod has a movable seal at its lower end inside the fourth hydraulic cylinder. When the third hydraulic rod moves up and down and squeezes the hydraulic oil in the third hydraulic cylinder, the hydraulic oil enters and exits the fourth hydraulic cylinder through the second hydraulic pipe, thereby driving the fourth hydraulic rod to move up and down synchronously with the third hydraulic rod.

[0047] The second hydraulic rod 11 has a movable seal at its lower end inside the second hydraulic cylinder 9. When the first hydraulic rod 8 moves up and down and squeezes the hydraulic oil in the first hydraulic cylinder 7, the hydraulic oil enters and exits the second hydraulic cylinder 9 through the first hydraulic pipe 10, thereby driving the second hydraulic rod 11 to move up and down synchronously with the first hydraulic rod 8.

[0055] The third hydraulic cylinder 16 is filled with hydraulic oil.

[0056] The third hydraulic rod 17 has its first end connected to the lower middle part of the electric push rod 4 via a crossbar. The third hydraulic rod 17 is symmetrically arranged with the first hydraulic rod 8. The second end of the third hydraulic rod 17 is movably sealed inside the third hydraulic cylinder 16. The third hydraulic rod 17 can move up and down synchronously with the electric push rod 4 and squeeze the hydraulic oil inside the third hydraulic cylinder 16.

[0057] The fourth hydraulic cylinder 18 is also equipped with hydraulic oil, and the fourth hydraulic cylinder 18 and the third hydraulic cylinder 16 are connected by the second hydraulic pipe 19; the second hydraulic pipe 19 is a flexible hydraulic pipe.

[0058] The fourth hydraulic rod 20 has a movable seal at its lower end inside the fourth hydraulic cylinder 18. When the third hydraulic rod 17 moves up and down and squeezes the hydraulic oil in the third hydraulic cylinder 16, the hydraulic oil enters and exits the fourth hydraulic cylinder 18 through the second hydraulic pipe 19, thereby driving the fourth hydraulic rod 20 to move up and down synchronously with the third hydraulic rod 17. The fourth hydraulic cylinder 18 and the fourth hydraulic rod 20 are located on the right side of the receiving cavity; the second hydraulic cylinder 9 and the second hydraulic rod 11 are located on the left side of the receiving cavity.

[0059] The lower part of the third linkage rod 21 is rotatably connected to the upper part of the fourth hydraulic rod 20 via a fifth rotating shaft;

[0060] The first end of the third latch 22 is rotatably connected to the upper part of the third linkage rod 21 through the sixth rotating shaft. The second end of the third latch 22 is a free end. The second end of the third latch 22 can rotate to the top of the pot lid 3 under the drive of the fourth hydraulic rod 20 and the third linkage rod 21 and lock the pot lid 3 at the opening of the pot body assembly 2. The second end of the second latch 13 can also rotate to the side of the pot lid 3 under the drive of the fourth hydraulic rod 20 and the third linkage rod 21, thereby releasing the locking of the pot lid 3.

[0061] The third high-voltage micro switch 23, which cooperates with the third latch 22, is triggered when the second end of the third latch 22 is rotated above the pot lid 3 and the pot lid 3 is locked at the opening of the pot body assembly 2, and is not triggered when the second end of the third latch 22 is rotated to the side of the pot lid 3 to release the locking of the pot lid 3.

[0062] The first high-voltage micro switch 14, the second high-voltage micro switch 15, and the third high-voltage micro switch 23 are all connected in series in the high-voltage circuit. Only when the first latch, the second latch, and the third latch simultaneously lock the lid will the first high-voltage micro switch 14, the second high-voltage micro switch 15, and the third high-voltage micro switch 23 be triggered. At this time, the high-voltage circuit in the main control circuit 30 will be connected, and the drive motor 29 will be energized and start working.

[0063] In addition, in this embodiment, the automatic lid-locking mechanism also includes a first distance detector 24 for measuring the vertical movement distance of the second hydraulic rod 11, a second distance detector 25 for measuring the vertical movement distance of the fourth hydraulic rod 20, a first regulator 26 connected to the second hydraulic cylinder 9 and capable of fine-tuning the hydraulic oil in the second hydraulic cylinder 9, and a second regulator 27 connected to the fourth hydraulic cylinder 18 and capable of fine-tuning the hydraulic oil in the fourth hydraulic cylinder 18; both the first distance detector 24 and the second distance detector 25 are laser rangefinders; wherein the first distance detector is electrically connected to the first regulator. The first distance detector 24 is electrically connected to the second regulator. When the travel of the second hydraulic rod 11 detected by the first distance detector 24 is out of sync with the electric push rod, the first regulator 26 automatically draws in or replenishes the hydraulic oil in the second hydraulic cylinder 9, thereby keeping the travel of the second hydraulic rod 11 consistent with the electric push rod. When the travel of the fourth hydraulic rod 20 detected by the second distance detector 25 is out of sync with the electric push rod, the second regulator 27 automatically draws in or replenishes the hydraulic oil in the fourth hydraulic cylinder 18, thereby keeping the travel of the fourth hydraulic rod 20 consistent with the electric push rod. Due to the volume processing error of the hydraulic rod or hydraulic pipe during actual production, there will be deviations in the travel of the first hydraulic rod, the third hydraulic rod, and the electric push rod on the left and right sides. At this time, through the two distance detectors and the regulator, when the piston travel of the left / right hydraulic rod is detected to be out of sync with the electric push rod, the regulator automatically draws in or replenishes the hydraulic medium in the cavity of the left and right hydraulic rods, thereby keeping the piston travel of the left / right hydraulic rod consistent with the electric push rod.
