A siphon auxiliary mechanism for a waterfall filter

Abstract

The invention relates to the technical field of fish tank sewage purification, and discloses a siphon auxiliary mechanism of a waterfall filter, which includes a filter box, a filter plate is movably installed on one side of the inner cavity of the filter box, and a filter plate is fixedly installed on one side of the inner cavity of the filter box. A water pump motor, one end of the front of the filter box is placed and fixedly connected with a water suction pipe. The invention adds a siphon auxiliary mechanism so that when the waterfall filter is started, the water pump rotor is driven by the water pump motor to rotate at a high speed, and the magnet moves outward along the guide plate under the action of centrifugal force, and the opening of the movable plug at the lower end increases. Down, it is pulled downward by the spring, and gradually moves outward with the magnet, and the movable plug slowly moves downward, so that the gas in the suction pipe at the inner end of the filter box is discharged, so that the water in the fish tank can be under the action of the siphon effect The water is pumped into the filter and assisted by the outlet hole, so that the gas in the suction pipe is continuously discharged, so that the waterfall filter can still start normally without adding water.

Description

technical field [0001] The invention relates to the technical field of fish tank sewage purification, in particular to a siphon auxiliary mechanism of a waterfall filter. Background technique [0002] The fish tank filter is a device used to purify water and supplement oxygen in fish farming appliances. Its purpose is to remove feces and other dirt in the water, keep the water clear, have sufficient oxygen, no harmful substances, and no pollution. It is suitable for the growth of fish. Only with a good filter device can fish be raised well and water needs to be changed less. The types of traditional fish tank filters are divided into gas-lift biochemical cotton filters, barrel-type external filters, aquarium top filters, and fish tank filters with shapes. device etc. [0003] The traditional waterfall filter is a kind of filter on the top of the aquarium. Through the rotation of the water pump, the suction pipe produces a siphon effect, and the water in the fish tank is pum...
