8502994-7 and MU 8902140-1), that is to say, that it is with volume system (with the cylinder of piston, piston and with milliliter
Regulating dosage) and themselves activation system；And " attachment sprayer ", such as PI 0204967-8 and MU
8500919-9, and the improvement thus proposed belongs to this kind.
(" preparation uses ") in the first scenario includes in the PI 0404632-3 and MU8502994-7 of suggestion
Major defect be that they are unsuitable for existing main back side sprayer in the market, and therefore, mainly when considering them
In the purposes on agricultural plant, user is required particularly to distribute in the hygienic operation for being related to liquid
The equipment of liquid.
In addition to this, MU8502994-7 proposes Activiation method (push-and-pull identical with previously cited PI 0101840-0
Type bar), this to use in rear cabinet, because activation device is maintained at except the range of operator, and therefore limits
Using higher volume of loadings (in tank) and distribute.
About MU8902140-1, although equipment tool there are two types of function (sprinkling and dosing application), physical limit be by
It cannot be accepted extensively by onsite user using available other tank/equipment, these tank/equipment in the market in it, and because
This, which limits the volume of capacity of will provided by the model and the capacity (counting by milliliter of milliliter) of the equipment.
In the case where " attachment sprayer ", about known technology, such as PI 0204967-8 and MU8500919-9,
