Title: FLOW PATCH SWITCHER AND LIQUID DETERGENT DISPENSING APPARATUS
Abstract:
A flow path switcher (1) provided with a valve core (1-1), a housing (1-2), and a base (1-3). Provided within the housing are valve base A (1-21), valve base B (1-22), a valve base A channel (1-23), a valve base B channel (1-24), an outflow opening (1-25), and an inflow opening (1-27). The base is provided with valve base C (1-31). Valve base A (1-21) and valve base B (1-22) are arranged in the direction of one side of the valve core (1-1); valve base C (1-31) is arranged in the direction of the other side of the valve core (1-1). The liquid detergent dispensing apparatus provided with the flow path switcher is provided with a main channel (2), a piston (6), one-way valve D (3), one-way valve E (5), detergent box A (4), and a Venturi vacuum generator (7). The flow path switcher (1) is connected between an inlet (7-2) of the Venturi vacuum generator and an outlet of the main channel. The inflow opening and the outflow opening of the flow path switch (1) respectively are connected to the outlet of the main channel and the inlet of the Venturi generator (7). The valve base B channel (1-24) is in communication with an outlet of one-way valve D (3). The outlet of one-way valve D (3) is in communication with the piston (6). An inlet of one-way valve D (3) is connected to detergent box A (4). An outlet of the piston (6) is in communication with one-way valve E (5). An outlet of one-way valve E (5) is in communication with a vacuum opening (7-3) of the Venturi vacuum generator (7). The apparatus is for use in dispensing a laundry detergent.
