Claims

[Scope of utility model registration request]

a battery, a motor connected to the battery via a power switch and a first switching element in series to drive a pump section, a liquid level detector provided at a discharge end of the pump section, and a motor connected to the battery through a power switch and a first switching element in series; controlling the first switching element to turn on in response to the liquid level non-detection output of the surface detector;
an element control circuit configured to turn off the first switching element in response to the liquid level detection output;
An electric pump comprising: a second switching element that turns on and off in response to the on and off operations of the element; and an alarm connected in parallel to the second switching element.
