Claims

[Claims for Utility Model Registration] (1) A chemical liquid tank 16 for storing a chemical liquid, and a plurality of compartments arranged in the chemical liquid tank 16 in the height direction of the chemical liquid tank 16 and partitioned from each other by partition walls 30. a control valve 38 which is disposed on the partition wall 30 and cuts off communication between the upper compartment 32 and the lower compartment 32 when a chemical solution is present in the lower compartment 32; and each compartment 32. a sensor 34 disposed in each compartment 32 to detect the presence or absence of a chemical solution in each compartment 32; a display section 28 that displays a display corresponding to a detection signal from the sensor 34;
2 and an orifice passage 26 that communicates the chemical solution tank 16 with the lower part of the chemical solution tank 16. (2) A communication hole 36 is formed in the partition wall 30, and the control valve 38 is provided integrally with a shaft portion 40 passing through the communication hole 36 and a lower end portion of this shaft portion 40, and the control valve 38 is provided integrally with the shaft portion 40 passing through the communication hole 36. from the bottom of the communication hole 36
A valve body 44 that can be opened and closed, and a valve body 44 that is integrally provided at the upper end of the shaft portion 40 and contacts the upper surface of the partition wall 30 near the communication hole 36 to prevent the flow of the shaft portion 40 from the communication hole 36 . Overhang part 42 that prevents it from coming off
The remaining amount detection device for a portable chemical sprayer according to claim 1, characterized in that the device has a specific gravity smaller than that of the chemical solution.
