Abstract
The invention discloses a liquid level sensor. The liquid level sensor comprises, a buoyant support, a floating ball connected with the bottom of the buoyant support, and a magnet arranged on the top of the buoyant support, wherein the buoyant support has a hollow structure, and is sheathed out of a main pipe in a relatively sliding manner; the main pipe has a top-opened cavity; a reed switch is arranged in the cavity, and is connected with a control terminal through an electrical wire; the remaining space of the cavity is filled with a waterproof sealing material; a pedestal is integrally formed on the top of the main pipe; and a mounting hole for fixing the liquid level sensor is formed on the pedestal. The liquid level sensor has the waterproof effect and can effectively prevent pins of the reed switch from being oxidized by air in the cavity by filling the remaining space of the cavity with the reed switch with the waterproof material, thereby prolonging the service life of the reed switch. A limit bump, a limit pin and the like are arranged to limit the work range of the liquid level sensor so as to prevent separation of the floating ball from the main pipe.
