AI Technical Summary

Technical Problem

Existing mechanical automatic feeding devices are prone to clogging and unstable drainage when handling high-viscosity cleaning liquids, especially piston-type extrusion mechanisms which have difficulty smoothly sucking in or extruding paste-like cleaning liquids.

Method used

Using water as the pressure medium, the piston column is driven to move through parallel and interlaced connecting rods. Combined with a one-way drainage device and a flexible bag, it achieves stable extrusion of high-viscosity cleaning liquid. The piston column is driven to reciprocate by water level changes to ensure quantitative release.

Benefits of technology

It achieves automatic, quantitative, and stable release of high-viscosity cleaning fluid, avoids clogging problems, improves the versatility and ease of maintenance of the device, and adapts to complex internal layouts of water tanks.

Abstract

The invention discloses a feeding device capable of automatically releasing cleaning liquid, and particularly relates to the technical field of bathroom equipment, and the feeding device comprises a static assembly, a floating assembly and a material box assembly. The static assembly comprises a base, a first connecting rod and a water injection tank; the floating assembly comprises a floating box, a second connecting rod and a balancing weight, and a piston column on the balancing weight is inserted into a piston pipe at the bottom of the water injection tank; the material box assembly comprises a flexible bag for packaging cleaning liquid, a discharging pipe and a material box body, the flexible bag is located in the material box body, the discharging pipe penetrates through the material box body, and an input pipe is arranged at the bottom of the material box body; a water inlet pipe and a water outlet pipe are arranged on the side portion of the water injection tank, and one-way valves are arranged in the water inlet pipe and the water outlet pipe. Water is adopted as a pressure medium and enters the material box body through the connecting hose to evenly extrude the surface of the flexible bag, so that the pasty cleaning liquid is extruded out and is not limited by the viscosity of the cleaning liquid, and automatic, quantitative and stable release of the high-viscosity cleaning liquid is achieved.
