[0029] like Figures 1 to 9As shown, a cream brush that pumps cream onto the surface of a brush head 1 includes a brush head 1, a brush base 2, an inner screw cap 3, a conduit 4, a cream cartridge 5, an outer cylinder 6, and a cream pumping structure 7. The brush head 1 is fixed to the top of the brush base 2, the brush base 2 is movably fitted inside the inner screw cap 3, the inner wall of the inner screw cap 3 has a spiral groove 8, the outer wall of the brush base 2 has a spiral protrusion 9, the spiral protrusion 9 slides along the spiral groove 8, the bottom of the inner screw cap 3 is rotatably connected to the cream cartridge 5, the top of the outer cylinder 6 has a top cover 10, and the conduit 4 passes through the top cover 10 and is fixedly connected to the top cover 10. The top cover 10 has several guide holes 11. The inner screw cap 3 is rotatably connected to the top of the outer cylinder 6. The bottom of the hair base 2 extends into the guide holes 11 with a guide rod 12. The guide rod 12 passes through the guide holes 11 and is connected to the top of the ointment pumping structure 7. The ointment pumping structure 7 is located inside the outer cylinder 6 and close to the top cover 10. The bottom of the conduit 4 is connected to the ointment pumping structure 7, and the top is inserted into the hair head 1. The top of the ointment tube 5 is sealed to the four sides of the ointment pumping structure 7. After pressing the ointment tube 5, the ointment in the ointment tube 5 flows along the ointment pumping structure 7 and the conduit 4 to the hair head 1.

[0030] like Figures 1 to 9 As shown, the paste cartridge 5 contains paste. Rotating the inner cap 3 causes the bristle seat 2 and bristle head 1 to move up and down along the inner cap 3. The bristle seat 2 drives the paste pumping structure 7 and the paste cartridge 5 to move up and down. When the inner cap 3 rotates in one direction, the bristle seat 2 and bristle head 1 move downwards along the inner cap 3. The bristle seat 2 drives the paste pumping structure 7 and the paste cartridge 5 to move downwards. After the bristle seat 2 and bristle head 1 move to a certain position, the top of the guide tube 4 extends beyond the surface of the bristle head 1, and the bottom of the paste cartridge 5 extends beyond the outer cylinder 6. When the bottom of the cream cartridge 5 is pressed, the cartridge 5 pushes the cream pumping structure 7, which draws the cream from the cartridge 5 into the guide tube 4. The cream flows along the guide tube 4 to the surface of the hair bristle head 1. When the inner cap 3 rotates in the other direction, the hair bristle base 2 and the hair bristle head 1 move upward along the inner cap 3. The hair bristle base 2 drives the cream pumping structure 7 and the cartridge 5 to move upward, and the cartridge 5 extends into the outer cartridge 6. The top of the guide tube 4 extends into the hair bristle head 1, leaving the cream on the surface of the hair bristle head 1, which can then clean the skin. The cream can be automatically directed to the surface of the hair bristle head 1, making it convenient, clean, and hygienic to use.

[0031] like Figures 1 to 9 As shown, the ointment pumping structure 7 includes a piston sleeve 13, a pump core 14, a return spring 15, a pump body seat 16, and a pump body 17.

The bottom of the conduit 4 communicates with the pump core 14, and the pump core 14 is fixedly connected to the top cover 10.

[0032] like Figures 1 to 9 As shown, when the inner cap 3 rotates in one direction, the bristle seat 2 and the bristle head 1 move downward along the inner cap 3. The bristle seat 2 and the bristle head 1 drive the paste pumping structure 7 and the paste cylinder 5 to move downward. After the bristle seat 2 and the bristle head 1 move to a certain position, the top of the guide tube 4 extends out of the surface of the bristle head 1, and the bottom of the paste cylinder 5 extends out of the outer cylinder 6. When the bottom of the paste cylinder 5 is pressed, the paste cylinder 5 pushes the pump body seat 16 and the pump body 17 to move upward. The air in the pump body 17 is discharged, and the pump body 17 is in a negative pressure state. When the paste cylinder 5 is released, under the action of the return spring 15, the return spring 15 pushes the pump body 17 to move downward. The paste in the paste cylinder 5 is sucked into the pump body 17 and flows along the pump core 14 to the guide tube 4.

[0033] like Figures 1 to 9 As shown, when the ointment cartridge 5 is pressed continuously, the ointment in the cartridge 5 can be continuously drawn into the pump body 17 and flow along the pump core 14 to the conduit 4, and finally flow to the surface of the hairpiece 1.

[0034] like Figures 1 to 9 As shown, the bottom outer wall of the pump core 14 is provided with an annular protrusion 18, and the pump core 14 is fitted with a fixing ring 27. The annular protrusion 18 contacts the inner wall of the pump body 17, and the fixing ring 27 contacts the inner wall of the pump body 17.

[0035] like Figures 1 to 9 As shown, a one-way valve (not marked in the figure) is provided at the bottom of the pump body 17. The one-way valve can prevent the paste in the pump body 17 from flowing to the paste cylinder 5.

[0036] like Figures 1 to 9 As shown, the inner wall of the outer cylinder 6 is provided with a guide groove 19, and the pump body seat 16 slides along the guide groove 19. When the inner screw cover 3 is rotated, the hair seat 2 and the hair head 1 move up and down along the inner screw cover 3, and the hair seat 2 and the hair head 1 drive the pump body seat 16 and the paste cylinder 5 to move up and down, and the pump body seat 16 slides along the guide groove 19.

[0037] like Figures 1 to 9 As shown, the ointment tube 5 includes a tube body 20 and a piston 21. The piston 21 is located inside the tube body 20. The bottom of the tube body 20 is provided with an air inlet 23, and the bottom of the tube body 20 is fitted with a pressure cap 22.

[0038] like Figures 1 to 9 As shown, the piston 21 has an annular groove 26 on the side near the ointment pumping structure, and the annular groove 26 is adapted to the bottom of the ointment pumping structure 7.

[0039] like Figures 1 to 9 As shown, piston 21 is located inside paste cylinder 5 and near the bottom of paste cylinder 5, which contains paste.

[0040] like Figures 1 to 9As shown, when the inner cap 3 rotates in one direction, the bristle seat 2 and the bristle head 1 move downward along the inner cap 3. The bristle seat 2 and the bristle head 1 drive the paste pumping structure 7 and the paste cylinder 5 to move downward. After the bristle seat 2 and the bristle head 1 move to a certain position, the top of the guide tube 4 extends out of the surface of the bristle head 1, and the bottom of the paste cylinder 5 extends out of the outer cylinder 6. When the bottom of the paste cylinder 5 is pressed, the paste cylinder 5 pushes the pump body seat 16 and the pump body 17 to move upward. The air in the pump body 17 is discharged, and the pump body 17 is in a negative pressure state. When the paste cylinder 5 is released, under the action of the return spring 15, the return spring 15 pushes the pump body 17 to move downward. The piston 21 pushes the paste in the paste cylinder 5 to move upward and is sucked into the pump body 17. The paste in the pump body 17 flows along the pump core 14 to the guide tube 4.

[0041] like Figures 1 to 9 As shown, the ointment cartridge 5 is detachably connected to the ointment pumping structure 7. The ointment cartridge 5 contains ointment, and when the ointment in the ointment cartridge 5 is used up, another ointment cartridge 5 can be replaced.

[0042] like Figures 1 to 9 As shown, an outer screw cap 24 is fitted over the inner screw cap 3, and the outer screw cap 24 is fixedly connected to the inner screw cap 3. The outer screw cap 24 protects the inner screw cap 3.
