The water level that the water tank 2 was added to the constant temperature is higher than the water level in the water bath, according to the linker principle, can know in the time that liquid adding hole 32 was not stopped up by the piston piece, the liquid that the constant temperature added the inside of water tank 2 can be because water pressure adds water tank 2 from the constant temperature and gets into the water bath through liquid adding pipe 9, liquid adding hole 32, the 3 headspace of cylindric piston shell in proper order, accomplishes the automatic process of adding liquid of constant temperature water.
The automatic liquid level control device 1 comprises a cylindrical piston shell 3 installed on the inner wall of the bottom end of a water bath tank through a fixing piece, overflow holes 31, liquid adding holes 32 and drain holes 33 are respectively formed in the bottom end of the left side, the top end of the right side and the bottom surface of the cylindrical piston shell 3, a sliding piston block 4 is inserted into the cylindrical piston shell 3, the sliding piston block 4 can slide up and down in the cylindrical piston shell 3, the side face of the sliding piston block 4 is attached to the inner side face of the cylindrical piston shell 3, and the effect of sealing and preventing water leakage is achieved.

The annular plate 7 can prevent the sliding piston block 4 from sliding out of the cylindrical piston shell 3, and the central hole of the annular plate 7 and the liquid adding hole 32 communicate the water bath with the constant temperature liquid adding tank 2, so that the addition of the constant temperature liquid is simpler.
The foam buoyancy block 6 is in a rectangular block shape, and a sealed space is arranged inside the foam buoyancy block 6. Namely, the foam buoyancy block 6 is made of hollow foam plastic, so that the occupied space is larger, the buoyancy is stronger, when the rectangular block-shaped foam buoyancy block 6 floats on the water surface of the water bath pool, the foam buoyancy block 6 is larger in buoyancy when sinking a little distance, and the bottom area in contact with water is larger, so that the sliding piston block 4 is pulled through the tension rope 5.
When the water level submerges the side surface of the foam buoyancy block 6 for a distance exceeding half of the height of the foam buoyancy block 6, the foam buoyancy block 6 can generate certain buoyancy to pull up the sliding piston block 4, the buoyancy at the moment is larger than the gravity of the sliding piston block 6 and the magnetic field attraction effect of the magnetic field force of the magnetic attraction block 41 on the iron block 42, and at the moment, water can be discharged through the overflow hole 31.

(2) as shown in fig. 3, when the height of the constant temperature liquid in the water bath is lower than the standard height, the liquid level is lowered, the position of the foam buoyancy block 6 is lowered, the traction pulling force of the foam buoyancy block 6 on the sliding piston block 4 is lowered, the sliding piston block 4 slides downwards in the cylindrical piston shell 3 under the dual acting force of the magnetic field suction force and the gravity, after the sliding piston block 4 slides downwards for a certain distance, the blockage of the liquid adding hole 32 is removed, and the constant temperature liquid in the constant temperature water adding tank 2 automatically flows into the water bath under the action of the gravity, so that the liquid adding process is completed;
(3) in the liquid adding process, the liquid level in the water bath tank continuously rises, so that the position of the foam buoyancy block 6 rises, the foam buoyancy block 6 gradually pulls up the sliding piston block 4, and when the liquid adding hole 32 is blocked again by the sliding piston block 4 (the foam buoyancy block 6 still blocks the inlet of the overflow hole 31), the liquid in the water bath tank meets the requirement at the moment, and the liquid is not added into the water bath tank any more;
(4) as shown in fig. 4, if the amount of the liquid to be added is too large, the foam buoyancy block 6 continues to rise, and at this time, the sliding piston block 4 blocks the liquid addition hole 32 to release the block between the drain hole 33 and the liquid addition hole 32, and at this time, the excess water in the water bath is drained from the drain hole 33, and after a certain amount of the liquid is drained, the liquid level in the water bath gradually drops, so that the sliding piston block 4 blocks the liquid addition hole 32 again, and the height of the liquid in the water bath is ensured to be stable.
