Description

Technical Field

[0001] This utility model relates to the field of water bath heating technology, specifically to a water bath with automatic water replenishment. Background Technology

[0002] A constant-temperature water bath is a commonly used heating device in laboratories, primarily for distillation, drying, and concentration of biological products. Existing water baths typically involve adding an appropriate amount of water before use and then heating to a predetermined temperature. However, when the constant-temperature heating time is long or continuous use is required, the water in the bath will gradually decrease due to evaporation, causing the water level to drop and affecting experimental results. If water is not replenished in time, the water bath may even dry out, potentially causing the heating element to fail and resulting in equipment damage.

[0003] Chinese Patent CN211385072U discloses an automatically replenishing water bath, comprising a water bath, a water storage device, and a water delivery device for conveying water from the storage device into the water bath. The water bath contains a detachable support rod with an adjustable bracket. The bracket has two contacts that act as switches and are electrically connected to the water delivery device. A crossbar is rotatably mounted at the bottom of the bracket, with a float connected to one end and a contact plate to the other. The contact plate has a conductive sheet connecting the two contacts. When the float is not floating, the conductive sheet is in close contact with the two contacts. This water bath automatically replenishes water, preventing continuous water loss or even dry burning, thus reducing the workload of laboratory personnel.

[0004] However, the above technical solution has the following shortcomings: In actual use, if the liquid level drops slightly, the float sinks and drives the conductive plate to contact the contact point through the crossbar and contact plate, and the circuit of the water supply device is connected to replenish water into the water bath. If the liquid level in the water bath rises slightly, the float floats up and the conductive plate separates from the contact point, causing the water supply device to start frequently, which seriously affects the service life of the device.
