The utility model belongs to the technical field of
public toilet energy conservation, and particularly relates to a
public toilet automatic timing flushing device which comprises a timing controller and an
electromagnetic valve, the
electromagnetic valve is arranged on one side of the timing controller, the top of the
electromagnetic valve is in threaded connection with a three-way connecting
pipe, and the top of the three-way connecting
pipe is connected with a rotor
booster pump. The liquid
discharge end of the rotor
booster pump is connected with a three-way connecting
pipe, the liquid suction end of the rotor
booster pump is in threaded connection with a water guide connecting pipe, the cross section of the water guide connecting pipe is of a right-angle structure, the end of the water guide connecting pipe is connected with an external filter, and the bottom of the external filter is in threaded connection with a filter
cartridge; an outer shell is arranged on the outer side of the filter
cartridge; according to the novel rotor booster pump, the effect of boosting
tap water can be achieved, the situation that the automatic flushing effect on a
public toilet is affected due to the fact that
pressure reduction and
water supply pressure are too low when the
tap water passes through an external filter is avoided, meanwhile, the
tap water can be filtered, the cleanliness of the tap water is guaranteed, and the service life of the electromagnetic valve is prolonged.
