Abstract

The invention discloses a liquid pump and a cleaning solution put-in system. The liquid pump comprises a feed port, a discharge port, a pump body, a feed valve, a discharge valve and a piston mechanism. The pump body comprises a liquid storage cavity used for storing liquid. The liquid storage cavity communicates with fluid of the feed port through a liquid inlet channel and communicates with fluid of the discharge port through a liquid outlet channel. The feed valve is coupled in the liquid inlet channel and is arranged to only allow liquid to flow to the liquid storage cavity from the feed port along the liquid inlet channel. The discharge valve is coupled in the liquid outlet channel and is arranged to only allow the liquid to flow to the discharge port from the liquid storage cavity along the liquid outlet channel. The piston mechanism comprises a piston rod, a piston and a piston driver. The piston makes contact with the inner wall of the pump body so as to limit the liquid storage cavity together with the inner wall of the pump body. The piston is connected to the first end of the piston rod. The piston rod is arranged to be driven by the piston driver to move in the axial direction of the pump body so as to drive the piston to move back and forth between the liquid suction position and the liquid discharge position in the pump body. By means of the liquid pump, the liquid put-in amount can be precisely controlled.

Description

technical field [0001] The present application relates to the technical field of liquid flow control, and in particular, relates to a liquid pump and a liquid delivery system. Background technique [0002] Washing liquid dosing systems are used to automatically add washing liquid to washing appliances such as washing machines. To inject low-pressure washing liquid into high-pressure tap water, the washing liquid dosing system usually includes a liquid pump. [0003] In the prior art, there are many types of liquid pumps, such as centrifugal pumps, reciprocating pumps, and vacuum pumps. The lotion pump is a reciprocating pump. Because of its simple structure and low price, the lotion pump is widely used in the field of daily chemicals. However, the lotion pump in the prior art is usually manually operated, and it is impossible to pump the washing liquid into the high-pressure liquid, and it is also impossible to realize accurate and quantitative delivery of the washing li...
