The cylinder end of the first cylinder 531 is hinged to the top of the chassis 12. Two mounting blocks 534 are arranged at intervals on the inner side wall of the chassis 12. The first rotating shaft 532 is horizontally rotatably connected between the two mounting blocks 534. The end of the swing arm 51 away from the cover grabbing mechanism 52 is fixedly connected to the first rotating shaft 532, and the first rotating shaft 532 is arranged perpendicularly to the swing arm 51.

The swing arm 51 is in the initial state, located above the weighing platform 4, and the two clamps 521 are in the open state. When the electric hot pot 2 is placed on the weighing platform 4, the second cylinder 5231 is driven by the button 123 to clamp the two clamps 521 on the cover handle.

[0044] Reference Figure 2 and Figure 5 The water adding device 6 includes a water tank 61, a water adding pipe 62 and a second driving mechanism 63. The side wall of the chassis 12 is horizontally extended outwardly and provided with an extension block 124. The upper surface of the extension block 124 is vertically fixed with a vertical rod 125. The water adding pipe 62 is horizontally arranged, and the water adding pipe 62 is rotatably connected with the vertical rod 125. The water adding pipe 62 in this embodiment is a metal hollow pipe. A water outlet 621 is downwardly arranged at the end of the water adding pipe 62. The side wall of the chassis 12 is horizontally provided with a second clearance opening 122, and one end of the water adding pipe 62 away from the water outlet 621 extends into the chassis 12. The water tank 61 is installed inside the chassis 12, and the water tank 61 is connected to the water adding pipe 62 through a hose, and the water pump arranged in the water tank 61 provides power and water supply. The second driving mechanism 63 drives the water adding pipe 62 to rotate, so that the water outlet 621 of the water adding pipe 62 is close to the top of the electric hot pot 2.

[0045] Reference Figure 2 and Figure 3 The second driving mechanism 63 includes a push rod 631, a reset member, and a pushing assembly 633. The push rod 631 is installed in the chassis 12. The pushing assembly 633 drives the push rod 631 to push the water adding pipe 62 to rotate, so that the water outlet 621 of the water adding pipe 62 is close to the top of the electric heating pot 2. The reset member is used to reset the water adding pipe 62. Specifically, the reset member is a torsion spring 632, which is installed at the rotation connection between the vertical rod 125 and the water adding pipe 62, so that the water adding pipe 62 has a torque force in the direction away from the electric heating pot 2.

[0046] Reference Figure 3The pushing assembly 633 includes a large gear 6331, a small gear 6332, a second rotating shaft 6333, a threaded rod 6334, a stopper 6335 and a stopper 6336. The large gear 6331 is coaxially fixed on the first rotating shaft 532. The second rotating shaft 6333 is rotatably connected between the two mounting blocks 534. The first rotating shaft 532 and the second rotating shaft 6333 are arranged in parallel. The small gear 6332 is coaxially fixed on the second rotating shaft 6333 and the small gear 6332 and the large gear 6331 are meshed with each other. The gear ratio of the small gear 6332 and the large gear 6331 in this embodiment is 1:5. One end of the second rotating shaft 6333 extends out of the mounting block 534 and is fixedly arranged with the threaded rod 6334. One end of the push rod 631 is tapped with a threaded hole.

The limit block 6336 is fixedly arranged between the side wall of the chassis 12 and the mounting block 534. The limit block 6336 is slidably connected to the limit block 6335 through the guide groove. During the process of the first cylinder 531 driving the first rotating shaft 532 to rotate, the large gear 6331 set on the first rotating shaft 532 drives the small gear 6332 to rotate, thereby rotating the threaded rod 6334 connected to the second rotating shaft 6333, and then the push rod 631 threadedly connected to the threaded rod 6334 moves to drive the water adding pipe 62 to rotate, so that the water adding pipe 62 can rotate during the process of removing the cap.

[0047] The implementation principle of the life tester of an electric hot pot in the embodiment of the present application is as follows: the electric hot pot 2 is placed on the weighing platform 4, and the second cylinder 5231 is operated by the button 123 to drive the two clamping claws 521 to clamp the cover handle on the cover body, and the controller receives the detection signal of the weight sensor. The weight of the electric hot pot 2 is lower than the preset water adding threshold set by the controller, and the controller controls the first cylinder 531 to drive the swing arm 51 upward to drive the cover body to separate from the electric hot pot 2. At the same time, during the rotation of the first cylinder 531, the large gear 6331 set on the first rotating shaft 532 drives the small gear 6332 to rotate, so that the threaded rod 6334 connected to the second rotating shaft 6333 rotates, and the rotation of the first cylinder 531 is realized. The push rod 631 threadedly connected to the threaded rod 6334 moves to push the water adding pipe 62 to rotate, so that the water outlet 621 of the water adding pipe 62 is located above the electric hot pot 2, and at the same time, the controller controls the water pump of the water tank 61 to supply water to the electric hot pot 2; when the weight of the electric hot pot 2 reaches a preset threshold value set by the controller to stop adding water, the water pump stops working, and at the same time, the first cylinder 531 drives the swing arm 51 to rotate downward and cover the electric hot pot 2. During the downward rotation of the swing arm 51, the push rod 631 moves to the end away from the water adding pipe 62, and the water adding pipe 62 is reset under the action of the torsion spring 632, thereby automatically completing the water adding to the electric hot pot 2. Compared with manual water adding, the labor cost can be greatly reduced.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
