Problems solved by technology

[0004] Since the existing centrifugal water pumps cannot pump and transport air, and the centrifugal air pumps cannot be used to pump and transport water
So it is not possible to use a centrifugal pump to remove the air from the filter and to pump the water
Existing products are usually equipped with a manual exhaust device or a dedicated air pump in the filter, which makes the structure complicated and troublesome in production and use
At the same time, in the prior art, there is a lack of a control circuit applied to a pump device that can pump water or air, and automatically control the drive signal of the circuit according to the working state of the pump device when pumping water or air, so as to realize the speed adjustment of the pump device

Abstract

The invention discloses a control circuit applied to a pump device and a water and air pumping control method. The pump device is used for pumping water and air, the control circuit comprises a detection feedback circuit used for obtaining working state information of the pump device and feeding the working state information back to a signal processing circuit, the signal processing circuit used for real-time adjustment of a driving signal sent to a power driving circuit according to the working state information and the power driving circuit used for driving a motor in the pump device to workaccording to the driving signal, and the control circuit is used for controlling the motor to run at the first rotating speed when the pump device is in the water pumping working state and controlling the motor to run at the second rotating speed when the pump device is in the air pumping working state, wherein the first rotating speed is smaller than the second rotating speed. According to the embodiment, the pump device can be controlled to achieve the air pumping and water pumping function at the same time, use and operation are facilitated, troubles are reduced, and the operation difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of drive control of a pump device, in particular to a control circuit applied to a pump device and a control method for pumping water and air. Background technique [0002] The progress of the times has made people have more and more leisure space. Keeping pets has become a kind of entertainment and a way to release stress. One of them is to keep pets or fish in aquariums or garden ponds, so aquariums, The garden pond has become one of the indispensable furniture or decorations in the home or work environment. [0003] Current aquariums and garden ponds are usually equipped with water treatment filters, which are connected to the water in the aquarium or garden pond by the water inlet pipe and the outlet pipe, and the water in the aquarium or garden pond is sucked by the water pump installed in the filter Filter, which is treated through the filter, filtered, and returned to the aquarium or garden pond. ...
