The distance between the float 26 and the rotation shaft 122a is adjusted by sliding the telescopic rod 25 in the axial direction of the second connecting rod 24.

Referring to fig. 2, fig. 2 is a cross-sectional view of the sliding connection between the second connecting rod 24 and the telescopic rod 25 according to the present invention. As shown in fig. 2, a ring-shaped limiting plate 24a is disposed on a cross section of a port of the second connecting rod 24, which is opposite to the inner wall 12 of the pot, and an inner diameter of the limiting plate 24a is larger than an outer diameter of the telescopic rod 25, so that the telescopic rod 25 can pass through the limiting plate 24 a. The outer side wall of the telescopic rod 25 positioned in the second connecting rod 24 is provided with a plurality of protrusions 25a which can be clamped and fixed on the inner side of the limiting plate 24a, so that the telescopic rod 25 cannot be separated from the second connecting rod 24. Preferably, the surfaces of the protrusions 25a are arc surfaces, and the arc surfaces are tangent to the inner side walls of the second connecting rods 24, so that the telescopic rods 25 can slide more smoothly in the second connecting rods 24.

Preferably, a rotating shaft horizontally penetrating through the second connecting rod 24 is disposed in the supporting hole 122, and the second connecting rod 24 can rotate around the rotating shaft 122a to fix the position of the second connecting rod 24 in the supporting hole 122a, thereby reducing the virtual position.

When a certain amount of water is filled in the water tank 13, the floating ball 26 floats on the water surface, and rises along with the rise of the water level, and the second rotating rod 24 is driven to rotate around the rotating shaft 122a by using the rotating shaft 122a arranged in the supporting hole 122 as a fulcrum through the lever principle, so that the slider 20 is driven to slide up and down by generating upward thrust or downward tension on the slider 20 through the fixed connection of the first connecting rod 22 and the slider 20, and the slider 20 in the accommodating space 11 is driven to cling to the outer wall 10 of the pot body and the inner wall 20 of the pot body to slide up and down.

The height from the limiting block 28 to the bottom 14 of the boiler is lower than the height from the first water inlet 100 to the bottom 14 of the boiler.

Further, the distance between the first water inlet 100 and the top of the outer wall 10 of the pot is greater than the height of the sliding block 20. The distance between the second water inlet 120 and the bottom 14 of the pot is smaller than the distance between the support hole 122 and the bottom 14 of the pot. When the water level in the water tank 13 is reduced to a certain degree, the second rotating rod 24 is driven to rotate clockwise around the rotating shaft 122a, so that the slider 20 is pushed upwards by the fixed connection between the first connecting rod 22 and the slider 20, the slider is completely separated from the first water inlet, and water can flow into the accommodating space 11 through the first water inlet 100. When the water level in the accommodating space 11 rises to the second water inlet 120, the water flows into the water tank 13 through the second water inlet 120.

In addition, the second water inlet 120 is located between the two partition plates, and the volume of the cavity is reduced, so that the water level lifting speed between the two partition plates is increased, and the water in the water tank 13 can be supplemented in a short time.

Before use, the sliding block 20 is moved to the top surface of the limiting block 28, and at the moment, the sliding block 20 completely covers the first water inlet 100 to block the first water inlet.

Along with the water bath heating, the water in the water tank 13 can evaporate gradually, the water level in the water tank 13 descends gradually, the buoyancy force borne by the floating ball 26 is reduced gradually, the height of the floating ball 26 is reduced along with the gravity, at the moment, the descending of the floating ball 26 drives the second connecting rod 24 to rotate clockwise around the rotating shaft 122a, an upward thrust is generated on the sliding block 20 through the first connecting rod 22, the sliding block 20 slides upwards, and the sliding block 20 is separated from the first water inlet 100. Water flows into the accommodating space 11 from the first water inlet 100 through the water inlet pipe, and when the water level in the accommodating space 11 reaches the height of the second water inlet 120, the water flows into the water tank 13 from the second water inlet 120, so that the water evaporated in the water tank 13 is supplemented, and automatic water supplement is realized. And with the continuous supplement of the water in the water tank 13, the water level in the water tank 13 gradually rises, and the buoyancy to the floating ball 26 is recovered, so that the floating ball 26 is lifted, at this time, the lifting of the floating ball 26 drives the second connecting rod 24 to rotate around the rotating shaft 122a in the clockwise direction, so that a downward pulling force is generated to the sliding block 20 through the first connecting rod 22, the sliding block 20 slides downward, so that the sliding block 20 slides to the position of the top surface of the limiting block 28, and completely covers the first water inlet 100, and the inflow of water is blocked. The automatic water supplement to the water tank 13 is realized through the above processes.

Compared with the prior art, the water supplementing device has the advantages that the two layers of side walls of the pot body are arranged, the water supplementing mechanism is arranged in the accommodating space formed between the outer wall of the pot body and the inner wall of the pot body, one end, positioned between the outer wall of the pot body and the inner wall of the pot body, of the water supplementing mechanism is used for plugging the water inlet, and the other end of the water supplementing mechanism extends into the water tank to sense the water level change in the water tank.
