<p>The utility model relates to a liquid leakage detection sensor and a base of the liquid leakage detection sensor. The liquid leakage detection sensor comprises a casing, and a base mounted on the bottom of the casing, wherein a fit surface tightly fit with the bottom of the casing, and a liquid guide section concavely arranged on the back side of the fit surface are arranged on the base; and a light projecting component and a light receiving component are accommodated in the casing. Light emitted from the light projection component is received by the light receiving component through the liquid guide section so as to determine whether a liquid exists in the liquid guide section or not according to the light reception amount. An air hole penetrating through the liquid guide section to the upper surface of the base is formed on the base; and a groove extending from the air hole to the outer edge of the fit surface is formed on the upper surface of the base. According to the utility model, a liquid is conveniently led into the liquid guide section by the liquid leakage detection device.</p> |
