Description

Liquid supply control device of sprayer Technical Field The utility model relates to the technical field of sprayer parts, in particular to a liquid supply control device of a sprayer. Background The spraying machine is used for spraying liquid (such as pesticide, liquid fertilizer and the like) onto plants in a mist form, the structure of the spraying machine comprises a power system, an air supply system, a spraying system and the like, the systems are not mutually independent, and in the design, manufacture and use processes, the spraying machine needs to be comprehensively considered from the aspects of manufacturing process, space arrangement, functional coordination and the like. For example, in a spraying system, a filter is used for filtering spraying liquid on a front pipeline of a spraying pump so as to avoid blockage caused by the fact that impurities reach a nozzle position, and when the spraying system is used for a certain period of time or the spraying pressure is obviously insufficient, the filter needs to be disassembled and cleaned, but the operation of temporarily disassembling and cleaning in spraying operation of the filter directly connected with a spraying liquid container is difficult to realize, and the design and the installation need to be carried out in consideration of convenience of disassembling and cleaning. For another example, in the spraying liquid container, corresponding orifices are formed on the connected functional components, and the orifices include a liquid discharge valve opening for discharging and storing the residual spraying liquid at the end of spraying operation, a liquid supply opening for connecting a spraying pipeline, a liquid level meter orifice for conveniently observing the liquid level in real time, a mounting opening for mounting a stirring mechanism and the like, so that the orifices increase the complexity of manufacturing and mounting and increase the leakage risk, and the simplified design of the orifices on the spraying liquid container is always an important consideration factor in the design and manufacturing process of the container. The inventors have devised improvements in spray systems, particularly in the liquid supply control portion of the spray, by combining the problem of temporary filter cleaning with the problem of simplified orifice of the spray liquid container. Disclosure of utility model The utility model aims to solve the technical problem of providing a sprayer liquid supply control device which improves the temporary cleaning convenience of a filter and is beneficial to simplifying the design of an orifice of a spraying liquid container. The technical scheme includes that the liquid supply control device of the spraying machine is connected between a spraying liquid container and a spraying pump and comprises a multi-position control valve and a filter, wherein the multi-position control valve comprises a valve body, a liquid supply connection port, a spraying connection port and a liquid discharge connection port are arranged on the valve body, the liquid supply connection port is used for being connected with the spraying liquid container, the spraying connection port is used for being connected with the filter, and an on-off liquid control mechanism is arranged on the valve body and is used for being independently communicated with the liquid supply connection port and the spraying connection port, the liquid supply connection port and the liquid discharge connection port or simultaneously isolating the liquid supply connection port, the spraying connection port and the liquid discharge connection port. As an optimized technical scheme, the on-off liquid control mechanism comprises a valve core, and the valve core is connected with a transposition operation structure. As the preferable technical scheme, the valve core is arranged in the valve body in a sealing and rotating manner, the spray connection port and the liquid discharge connection port are oppositely arranged in the radial direction of the valve core, a liquid inlet channel which is always communicated with the liquid supply connection port is arranged at the inner end of the valve core, a liquid outlet channel which is communicated with the liquid inlet channel is also radially arranged on the valve core, and the liquid outlet channel is used for being independently communicated with the spray connection port, the liquid discharge connection port or the spray connection port and the liquid discharge connection port and is simultaneously separated. As a preferred technical solution, the transposition operation structure includes an operation handle. As an optimal technical scheme, the liquid supply connector is in threaded connection with the spraying liquid container. As the preferable technical scheme, threaded connectors are respectively arranged at the spray connection port and the liquid inlet of the filter, and a connecting hose is hooped between the two
