Automatic liquid supply device

Abstract

The invention discloses an automatic liquid supply device comprising a base, wherein the upper part of the base is provided with a liquid tank; the lower part of the liquid tank is provided with a liquid outlet mouth; the lower part of the base is provided with a pump body matched with the liquid outlet mouth; an inner cavity of the tail of the pump body is matched with a piston in a sliding way; the tail end of the piston is provided with a link; the lower part of the base is also matched with a motor; the motor is driven by a gearbox and has a lever; the lever is connected with the link and is used for controlling the reciprocating operation of the piston; the power transmission is realized by a lever principle; the automatic liquid supply device has simple structure and stable operation; the lever can achieve the purpose of regulating a linear motion distance by regulating a center distance; the linear motion distance is not limited by an eccentric distance of an eccentric wheel any more; the lever has strong suitability; the regulation of the center distance of the lever is beneficial to reducing power loss; a sealing gasket is configured for completely sealing a space between the pump body and the liquid outlet mouth and enhancing the cleanness of an appliance; a spherical ball rotates flexibly and is difficult to block; and the normal close of the liquid outlet mouth is finally realized by an elastic principle, thereby enhancing the cleanness of a surrounding environment.

Description

technical field [0001] The invention relates to the technical field of cleaning liquid distribution equipment, in particular to an automatic liquid supply device. Background technique [0002] At present, the known automatic induction liquid supply device uses the gear to drive the eccentric wheel, and the connecting rod drives the piston to reciprocate in the pump body to achieve the purpose of liquid supply; this type of liquid supply device is often limited by the movable distance and the capacity of the motor. limited by the applied load. [0003] Automatic liquid fetcher in the prior art, as the patent No. is the Chinese patent document " automatic liquid fetcher " of CN02250249.1 (announcement number is CN2580886Y); The liquid outlet in the liquid storage box is sealed and connected, and its liquid discharge port discharges hand sanitizer from the through hole of the base. An infrared sensing device is arranged near the liquid discharge port of the base, and a control...

Problems solved by technology

This design uses a solenoid valve as the on-off switch. Since the hand sanitizer is a viscous liquid, if it is not used for a long time, it will easily cause the viscosity to increase and block the solenoid valve core, which will cause the appliance to fail; the discharge of the liquid is based on the liquid potential difference, without other attachments. Power-assisted, the liquid flow moves slowly, and the speed is unstable, sometimes due to the small amount of liquid in the hand sanitizer bottle, it cannot be discharged
