Description

Technical Field

[0001] The utility model belongs to the technical field of liquid level gauges, and in particular relates to a liquid level gauge with a liquid level alarm function. Background Art

[0002] Modern liquid coolers are equipped with internal liquid level gauges. These gauges provide visibility into the liquid level during addition, preventing overfilling or a decrease in liquid level, which could cause system failures. However, gauges that only display the liquid level rely on manual inspection, which can be easily overlooked. If the liquid level is low and staff fail to observe it promptly, this can lead to system failures and even shorten the life of the pump.

[0003] A utility model patent, published as CN 214309038 U, discloses a liquid level gauge with a liquid level alarm function. The gauge includes a cylinder and a float. The outer surface of the cylinder is provided with a high level gauge and a low level gauge, sequentially arranged from top to bottom. The inner cavity of the cylinder is provided with an upper and lower float limit ring, with the ends of the float slidingly disposed within the upper and lower float limit rings, respectively. A float mounting rod is fixed to the upper end of the float, which slides through the upper end of the cylinder and connects to the float connection line. This liquid level gauge with a liquid level alarm function can reduce losses caused by liquid level failures due to neglected liquid levels; it allows for easy observation of the float's usage, preventing false alarms caused by jamming; and it reduces the impact of liquid surface disturbances on the float during return and suction.

[0004] Regarding the above-mentioned related technologies, the utility model applicant believes that there are the following defects:

[0005] 1. The limit plate in the above structure is fixed inside the liquid level gauge, and the position of the high and low limit plates cannot be adjusted according to actual needs. Moreover, when the float in the liquid level gauge is driven to move inside, the float movement trajectory will deviate, which will lead to inaccurate readings.

[0006] Therefore, it is necessary to provide a new liquid level meter with liquid level alarm function to solve the above technical problems. Utility Model Content
