Automatic water level control water pump

Abstract

The invention provides an automatic water level control water pump. The automatic water level control water pump comprises a pump shell, an impeller, a water level detecting assembly, a control board and a motor. The motor and the impeller are arranged in a motor chamber and an impeller chamber of the pump shell respectively. The impeller is arranged on a rotating shaft of the motor, wherein the rotating shaft extends to the impeller chamber. The water level detecting assembly comprises a fixing shell, a detecting board and three water induction heads. The three water induction heads are located at different heights and connected to the detecting board. The fixing shell is fixed to the pump shell, the detecting board is installed in the fixing shell in a sealing mode, and at least one part of each water induction head is exposed out of the fixing shell. The control board is connected to the detecting board and drives the motor to run according to water induction head detecting signals from the detecting board. The motor is controlled to run according to the water level detected by the three water induction heads and the detecting signals, and the water level in an aquarium or an electric appliance device can be automatically controlled.

Description

technical field

[0001] The invention relates to the field of water pumps, more specifically, to a water pump that can be used in aquariums or electrical equipment for automatic water level control. Background technique

[0002] The aquarium, also known as the aquarium or the aquarium, is a container specially used for raising ornamental aquatic animals and plants. Usually, at least one side is transparent glass or high-strength plastic. Aquariums contain water-dwelling plants and animals (usually fish, but also invertebrates, amphibians, marine mammals or reptiles) in captivity.

[0003] During the use of the aquarium, the water will continue to volatilize, resulting in a decrease in the liquid level. If water is not added in time, the liquid level will be too low, which will affect the growth space of animals and plants in the aquarium, and even cause the death of animals and plants. So in order for the aquarium to maintain a liquid level, water needs to be added to it fr...
