the first piston 12 moves downwards to convey the air in the first piston cylinder 8 into the storage tank 1 through the air outlet pipe 29 and the second one-way valve 30, so that the pressure in the storage tank 1 can be increased, the air is conveyed into the chute 36 through the air supply groove 32 because the storage tank 1 is in an overpressure state, and the sealing block 35 and the limiting block 34 can be driven to move because the air pressure is higher than the elasticity of the second spring 37, so that the limiting block 34 is tightly clamped into the limiting groove 33;
meanwhile, air enters the annular air bag 14 through the air inlet pipe 31, the annular air bag 14 expands to prop against the outer wall of the first piston cylinder 8, and the alginate impression powder can be stored in a sealing mode by matching with the rubber sealing ring 7, so that the alginate impression powder is not easy to damp;
when the alginate impression powder needs to be taken out, a user starts the motor 24 and opens the valve, the motor 24 works to drive the rake-shaped rotating rod 25, the shaft rod 26 and the gear 27 to rotate, the rake-shaped rotating rod 25 can stir and drive the alginate impression powder, the aim of stirring and driving the rake-shaped rotating rod 25 is fulfilled, because the alginate impression powder is vibrated possibly because of vibration in the conveying process of the storage tank 1, the alginate impression powder is more compacted, the fluidity of the alginate impression powder is reduced, and the rake-shaped rotating rod 25 rotates to loosen the alginate impression powder at the lower pipe orifice of the feeding pipe 5, so that the fluidity of the alginate impression powder is increased;
after the valve is opened, because the storage tank 1 is in an overpressure state, air is rapidly discharged through the discharge pipe 4, when high-speed air passes through the discharge pipe 4, high-speed air flows through the tubules and the pipe orifice of the feed pipe 5, so that the pressure at the upper end of the feed pipe 5 is smaller than the pressure at the pipe orifice at the lower end of the feed pipe 5, a pressure difference is formed between the two pressure differences, the loosened alginate impression powder can be pressed into the discharge pipe 4, and finally the alginate impression powder is sprayed out along with the air, so that the alginate impression powder can be taken out, a cloth bag can be arranged on the discharge pipe 4, and the sprayed alginate impression powder can be buffered and limited for collection, thus avoiding the problem that the alginate impression powder in the tank is wetted when the cover is opened in the past;
secondly, the gear 27 rotates to drive the short rod 23 and the circular plate 28 to rotate, the second piston 20 can reciprocate in the second piston cylinder 19 under the transmission of the connecting rod 21, when the second piston 20 moves close to the motor 24, external air can enter the second piston cylinder 19 through the air inlet short tube, when the second piston 20 moves far away from the motor 24, the air in the second piston cylinder 19 can be conveyed into the storage tank 1, the air conveyed into the storage tank 1 in the same time is similar to the air discharged through the discharge pipe 4 or slightly larger than the air outlet, and the rotating speed of the motor 24 or the size of the second piston cylinder 19 can be set according to requirements; wherein, the air conveyed into the storage tank 1 is subjected to moisture absorption treatment through a moisture absorption bag;
if the sealing performance between the sealing cover 6 and the storage tank 1 is poor, the alginate impression powder is affected with damp, and the sealing cover 6 and the storage tank 1 are poor in sealing performance or poor in sealing performance due to other reasons, air in the storage tank 1 is discharged, so that the pressure in the storage tank 1 is reduced, the reset of the sealing block 35 and the limiting block 34 is realized under the action of the second spring 37, the first piston cylinder 8 is not limited, the sliding ring 16, the first piston cylinder 8 and the sealing cover 6 are realized under the action of the first spring 17, the sealing cover 6 is not propped against the storage tank 1, and therefore, whether the alginate impression powder is affected with damp can be known only by observing whether the sealing cover 6 is propped against the storage tank 1, and the situation can be known more conveniently.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
