[0028] See Figures 1 to 7 This utility model provides a self-stirring dry powder pump, including a bottle body 1 and a cap 2 movably mounted on the top of the bottle body 1. A pump body 3 is installed inside the bottle body 1, and a piston 4 is movably mounted inside the pump body 3. The end of the piston 4 is connected to the cap 2 via a spring seat 5. The spring seat 5 and the piston 4 are sealed by a sealing ring 6. The lower end of the pump body 3 is connected to a feed pipe 7, which contains a spiral 8 and its bottom is connected to the inside of the bottle body 1. The spring seat 5 contains beads 9 that cooperate with the spiral 8. Positioning parts 29 are symmetrically arranged on both sides of the beads 9. The inner wall of the spiral 8 has a spiral groove 30, and the positioning parts 29 are placed in the spiral groove 30. When the spring seat 5 drives the beads 9 to descend, the spiral 8 can be driven by the cooperation of the spiral groove 30 and the positioning parts 29. The feed pipe 7 is rotated, and a stirring device connected to the spiral 8 is movably installed at the bottom. Therefore, when the cap 2 is pressed down, the spiral 8 drives the stirring device to rotate and stir the dry powder in the bottle 1, preventing the dry powder in the bottle 1 from accumulating and clogging. Specifically, the sealing ring 6 is embedded in the bottom of the spring seat 5, and the upper end of the piston 4 is surrounded by a flange 28. The sealing ring 6 is provided with an annular groove 10. When the cap 2 drives the piston 4 downward, the piston 4 is upward relative to the sealing ring. At this time, the flange 28 is inserted into the annular groove 10 to seal, which can isolate the external air and improve the discharge effect. When the piston 4 is reset, the flange 28 will disengage from the annular groove 10, so that a gap appears again between the sealing ring 6 and the piston 4. At this time, the spring seat 5 is ventilated to the outside.

[0029] In some embodiments, such as Figures 1-3 As shown, the spring seat 5 is provided with a first positioning seat 11, the top of the bead 9 is inserted into the first positioning seat 11, the bottom of the pump body 3 is provided with a second positioning seat 12, the outside of the bead 9 is fitted with a flexible tube 13, the two ends of the flexible tube 13 are respectively fixed on the first positioning seat 11 and the second positioning seat 12, the flexible tube 13 plays a sealing role, and the flexible tube 13 will contract during the descent of the bead 9; the stirring device is a rotating disk 14 installed at the bottom of the feed pipe 7, the bottom of the pump body 3 is also provided with a connecting pipe 15, the connecting pipe 15 is located on one side of the feed pipe 7, the bottom of the feed pipe 7 is provided with a connecting seat 16, and the bottom of the connecting pipe 15 is bent and inserted into the connecting seat 16.

[0030] In some embodiments, such as Figure 4 and Figure 5 As shown, the rotating disk 14 is equipped with arc-shaped paddles 17, and a connecting post 18 is provided inside the rotating disk 14. The feed pipe 7 is also equipped with a connecting rod 19 connected to the bottom of the spiral 8. The connecting post 18 passes through the feed pipe 7 and is fixed to the bottom of the connecting rod 19. The spiral 8 can drive the connecting post 18 and the rotating disk 14 to rotate as a whole via the connecting rod 19, thereby stirring through the paddles 17. The bottom of the feed pipe 7 is provided with a first powder inlet 20, and the connecting post 18 is correspondingly provided with a second powder inlet 21. The pump body 3 is equipped with a first valve plate 22 at the connecting pipe 15. During the rotation of the rotating disk 14, the first powder inlet 20 overlaps with the second powder inlet 21. At this time, the dry powder inside the bottle 1 can enter the feed pipe 7. When the cap 2 drives the piston 4 to press down, the first valve plate 22 opens, and the dry powder at the bottom of the feed pipe 7 is sprayed upward by air pressure to achieve discharge. In this embodiment, the feed pipe 7 and the beads 8 are hollow and connected to the cap 2 along the same center line. The dry powder at the bottom of the feed pipe 7 can be directly discharged from the cap 2. The powder is ejected from cap 2. When piston 4 rises, the first valve plate 22 closes to prevent dry powder from entering pump body 3 along connecting pipe 15. Air pressure can draw dry powder from bottle 1 into feed pipe 7. In this embodiment, the top of bottle 1 is provided with shoulder sleeve 23. Spring seat 5 passes through shoulder sleeve 23 and is fitted with return spring 24. Cap 2 is movably inserted into shoulder sleeve 23. Return spring 24 abuts against cap 2. Return spring 24 can drive cap 2 to be pressed and reset. The top of spring seat 5 is equipped with a second valve. The top of the spring seat 5 is through the plate 26. The first positioning seat 11 is equipped with an upper spring 27. The upper spring 27 pushes out the second valve plate 26 to seal the spring seat 5. The head cap 2 is equipped with a flexible pressing member 25. The bottom of the pressing member 25 can pass through the spring seat 5 to press down the second valve plate 26. When the head cap 2 is pressed down, the pressing member 25 can be opened to open the second valve plate 26. At this time, the dry powder can be sprayed out from the spray nozzle on one side of the head cap 2 through the spring seat 5. The pressing member 25 can automatically spring back to its original position after the material is discharged.

[0031] This utility model provides a self-stirring dry powder pump. When the cap is pressed, dry powder is sprayed out. When the cap is released, it rebounds and the internal pump body draws in the dry powder. When this process is repeated, the lower rotating disk can be driven to rotate back and forth by the cooperation of the beads and the spiral. The blades on the rotating disk continuously stir the dry powder inside the bottle, which can prevent the dry powder from hardening and causing the nozzle to become clogged after long-term use, and the sprayed dry powder is also more uniform.
