Water level alarm device for bathtub

Abstract

The invention discloses a water level alarm device for a bathtub. The device comprises a transparent casing, wherein a hook is placed on the upper end of the transparent casing, the lower end of the hook is fixed with a first foam block, a buzzer is installed in the middle of the first foam block, a hard wire connected in series with the buzzer penetrates through the lower end of the first foam block, the lower end of the first foam block is fixedly connected to the second foam block by a thin wire, the upper end of the second foam block is bonded and connected with a mosquito-repellent copperwire by a double-sided tape, the front end of the transparent casing is provided with a scale line, the left side of the transparent casing is provided with a bathtub, the buckle fixed at the left end of the transparent casing is clamped with the buckle fixed at the right end of the bathtub, and the inner wall of the socket opened at the right end of the bathtub is fixed with a sealing rubber strip. By setting the buzzer, the mosquito-repellent copper wire, the sealing rubber strip and the buckle, the water level alarm device for a bathtub solves the problems of complicated structure, expensive cost, bad effect, difficult installation and disassembly, and too large gap and easy water leakage after the installation.

Description

technical field [0001] The invention relates to the technical field of water level alarms, in particular to a bathtub water level alarm. Background technique [0002] The water level alarm refers to the alarm of the water level by means of mechanical or magnetic induction. It can control the start or stop of water pumps and other equipment at the same time with sound and light alarms or magnetic alarms. There are many methods, which vary according to the selection of different products. For example, the electronic water level switch detects the water level through the electronic probe, and then processes the detected signal by the special chip for water level detection. When the measured liquid reaches the action point, it outputs a high or low level signal, and then cooperates with the water level controller. , Output the relay switch signal, or directly supply power to the alarm, so as to realize the alarm function of the liquid level, and can also perform the water level ...
