DISPOSITIF DE PULVERISATION DE PEINTURE

摘要

The polymerizable liquid sprayer comprises a storage chamber (3) provided for receiving the polymerizable liquid, a spray nozzle (4), a conduit (5) for connecting the nozzle to an inner region (6) of the storage chamber intended to receive the polymerizable liquid, a pump (7) adapted to pressurize the inner region of the storage chamber by pumping a fluid to the storage chamber, a valve (8) selectively allowing the supply of the polymerizable liquid in the nozzle via the connecting conduit, and a deformable container (9) placed in the inner region of the storage chamber. The polymerizable liquid sprayer comprises a storage chamber (3) provided for receiving the polymerizable liquid, a spray nozzle (4), a conduit (5) for connecting the nozzle to an inner region (6) of the storage chamber intended to receive the polymerizable liquid, a pump (7) adapted to pressurize the inner region of the storage chamber by pumping a fluid to the storage chamber, a valve (8) selectively allowing the supply of the polymerizable liquid in the nozzle via the connecting conduit, a deformable container (9) placed in the inner region of the storage chamber and adapted to receive the polymerizable liquid to be sprayed, and a pressure accumulation chamber connected to the storage chamber. The connecting conduit is sealingly connected to the deformable container, where the sealed connection is adapted to transfer the polymerizable liquid from the deformable container to the connecting conduit without contacting the polymerizable liquid with a wall of the storage chamber. The deformable container, the connecting conduit and the nozzle are removable and detachable from the storage chamber, the pump and the valve. The pump: is an air pump comprising a manual actuating unit adapted to pump air in the sprayer and to transfer the air to the storage chamber when the actuating unit is operated; and comprises a pump body mechanically assembled to the storage chamber to form a rigid assembly. The deformable container comprises a pocket forming a flexible wall that is deformable from the deformable container, a rigid portion, and internal chambers separated from one another by walls. The connecting conduit and the storage chamber comprise an assembly unit. The assembly unit is complementary assembly region formed on the rigid portion of the deformable container so as to immobilize the rigid portion of the deformable container. One of the internal chambers contains a first liquid polymerizable component that is a hardener. Another internal chamber contains a second liquid polymerizable component that is a polymerizable base when mixed with the hardener, and a third liquid polymerizable component that is diluent to dilute the polymerizable base. Each wall separating the internal chambers from the deformable container is breakable under the effect of deformation of the container. The deformable container is dimensioned for breakable walls while maintaining the container tightly closed. The pressure accumulation chamber has an internal volume of greater than 80% of the internal volume of the storage chamber. An independent claim is included for a polymerizable liquid shell for distributing polymerizable liquid in a sprayer.
