Abstract

The invention discloses a miniature water fullness alarm and a tea tray, and is characterized in that the miniature water fullness alarm comprises a circuit board, and the circuit board comprises a power supply wiring end CN2, a triode q1, a triode q2, a resistor R1, a buzzer BZ1 and a contact elastic sheet wiring end CN1; the tea tray comprises a tea tray base (1), a circuit board installation groove is preset in the tea tray base (1), the opening direction of the circuit board installation groove faces the outside of a container, and the miniature water fullness alarm is installed in the circuit board installation groove. According to the design of the position of the circuit board, all devices except a contact elastic sheet are not in contact with water; 3v voltage is adopted, no high voltage is generated, and no influence is caused to the human body; and the 40ma current buzzer is extremely low in power consumption and small in driving current, and the signal end is short-circuitedfor a short time without causing a fire hazard.

Description

technical field [0001] The invention relates to the field of alarms, in particular to a miniature full water alarm and a tea tray. Background technique [0002] In production and life, when the liquid level in the container rises to a certain level, it is often necessary to remind relevant personnel in time to avoid unnecessary troubles in production and life. Existing full water alarms are large in size and are not suitable for some smaller containers, such as common tea trays. When the tea in the tea tray is poured too much, it will overflow from the tea tray, causing a mess and destroying people’s tea tasting The elegant mood of the time. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a miniature full water alarm and a tea tray. [0004] The technical scheme adopted in the present invention is: [0005] A miniature full water alarm, characterized in that it includes a circuit bo...
