Description

Technical Field

[0001] This application belongs to the field of facial mask production technology, specifically a device for injecting facial mask essence. Background Technology

[0002] In the production of facial masks, the equipment used for essence injection is the core equipment for achieving efficient and precise filling. With the development of the skincare industry, the market's demands for mask production volume and filling accuracy are constantly increasing, driving the technological upgrade of injection equipment. Traditional mask filling often relies on manual or semi-automatic equipment, resulting in low efficiency, large errors, and difficulty in meeting the needs of industrial production and quality control. With the development of automation technology, fully automatic filling equipment is gradually becoming the mainstream. This type of equipment generally integrates functions such as automatic bag unloading, bag opening, filling, sealing, coding, and output, significantly improving production efficiency and product consistency.

[0003] However, common facial mask essence injection devices use a fixed nozzle, which can easily lead to uneven distribution of the essence. The essence can also drip from the nozzle, contaminating the device and the external environment. A pump is needed to feed the essence, which wastes resources. Utility Model Content

[0004] The purpose of this application is to provide an injection device for facial mask essence in order to solve the problems mentioned above.

[0005] The technical solution adopted in this application is as follows: an injection device for facial mask essence, comprising an injection device and a base, wherein the injection device comprises an infusion structure, a power structure, and an anti-drip structure, wherein the infusion structure comprises an essence storage tank, an inlet pipe, and an injection cylinder, wherein the power structure comprises a cylinder, a cylinder push rod, and a force transmission rod, and wherein the anti-drip structure comprises an anti-leakage rod, a hemispherical outlet, a hemispherical anti-leakage head, and an injection piston rod.

[0006] By adopting the above technical solution, during the operation of the equipment, the cylinder is activated, and the cylinder push rod drives the transmission rod to descend. The descent of the transmission rod drives the injection piston rod to descend along the inner side of the injection cylinder. When the injection piston and injection piston rod descend, the anti-leak rod, under the action of a strong spring, keeps the hemispherical anti-leak head in close contact with the inner wall of the hemispherical outlet. The descent of the injection piston squeezes the essence inside the injection cylinder, and the essence pushes the hemispherical anti-leak head downward. It is then sprayed onto the mask through the gap between the hemispherical outlet and the hemispherical anti-leak head, which allows the essence to be sprayed out in a dispersed manner, making it better absorbed by the mask.

[0007] After the irrigation is completed, the cylinder push rod drives the force transmission rod to rise, which in turn drives the injection piston rod to rise. Under the action of the strong spring, the anti-leak rod keeps the hemispherical anti-leak head in close contact with the inner wall of the hemispherical discharge port. This allows the liquid adhering to the inside of the injection cylinder to flow out through the hemispherical discharge port and leak to the outside of the equipment, preventing pollution of the equipment and the external environment.

[0008] When the injection piston rises, the hemispherical anti-leak head blocks the hemispherical discharge port, reducing the pressure inside the injection cylinder. When the injection piston rises higher than the inlet, the essence will fill the essence storage tank under atmospheric pressure and be automatically injected into the injection cylinder through the inlet pipe, achieving automatic feeding without the need for a pump, thus saving the company's resources.

[0009] In a preferred embodiment, an injection piston slides on the inner side of the injection cylinder, and an injection piston rod is fixedly connected to the upper central axis of the injection piston. A leak-proof rod sliding cavity is formed along the central axis on the inner side of the injection piston and the injection piston rod. A leak-proof rod piston is slidably connected to the inner side of the leak-proof rod sliding cavity. A leak-proof rod is fixedly connected to the lower side of the leak-proof rod piston. A hemispherical leak-proof head is fixedly connected to the lower side of the leak-proof rod. A strong spring is fixedly connected to the lower side of the leak-proof rod piston. The inner side of the strong spring is sleeved on the outer side of the leak-proof rod. The injection piston is fixedly connected to the lower side of the strong spring.

[0010] By adopting the above technical solution, after the irrigation is completed, the cylinder drives the transmission rod through the cylinder push rod to rise, and drives the injection piston to rise through the injection piston rod. Under the action of the strong spring, the anti-leak rod will keep the hemispherical anti-leak head in close contact with the inner wall of the hemispherical discharge port. The liquid attached inside the injection cylinder can flow out through the hemispherical discharge port and leak to the outside of the equipment, which can prevent pollution of the equipment and the external environment.

[0011] In a preferred embodiment, a back plate is fixedly connected to the upper back side of the base, a liquid injection cylinder fixing bracket is fixedly connected to the front of the back plate, a liquid injection cylinder is fixedly connected to the inner side of the liquid injection cylinder fixing bracket, and a hemispherical discharge port is fixedly connected to the lower part of the liquid injection cylinder.

[0012] By adopting the above technical solution, the injection cylinder can be fixed by the injection cylinder fixing bracket, ensuring the stable operation of the equipment.

[0013] In a preferred embodiment, a top plate is fixedly connected above the back plate, a cylinder is fixedly connected above the top plate, a cylinder push rod is slidably connected below the cylinder, a force transmission rod is fixedly connected below the cylinder push rod, and an injection piston rod is fixedly connected below the force transmission rod.

[0014] By adopting the above technical solution, the power of the equipment operation can be improved, driving the injection piston below the injection piston rod to rise or fall in the injection cylinder.

[0015] In a preferred embodiment, a liquid injection piston sealing ring is fixedly connected to the side of the injection piston, and the outer side of the liquid injection piston sealing ring slides against the inner side of the injection cylinder.

[0016] By adopting the above technical solution, the airtightness of the injection cylinder can be guaranteed, providing power for the automatic feeding of the equipment.

[0017] In a preferred embodiment, an inlet plug rod is fixedly connected to the upper side of the injection piston, and the outer side of the inlet plug rod is slidably connected to the inner side of the injection cylinder, covering the inlet port opened on the side of the injection cylinder.

[0018] By adopting the above technical solution, it is possible to prevent the essence from flowing into the area above the injection piston when the injection piston descends.

[0019] In a preferred embodiment, a through-hole is provided above the anti-leakage rod piston.

[0020] By adopting the above technical solution, it can be ensured that the sliding of the anti-leakage rod piston in the anti-leakage rod sliding cavity is not affected by the internal air pressure.

[0021] In a preferred embodiment, an essence storage tank is fixedly connected to the front of the back plate, an essence storage tank level measuring window is fixedly connected to the side of the essence storage tank, an essence storage tank filling port is opened on the top of the essence storage tank, an inlet pipe is fixedly connected to the front of the essence storage tank, and an inlet is fixedly connected to the front end of the inlet pipe.

[0022] By adopting the above technical solution, it is convenient to supply materials to the equipment.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: During operation, the cylinder is activated, and the cylinder push rod drives the transmission rod to descend. The descent of the transmission rod drives the injection piston rod to descend along the inner side of the injection cylinder. As the injection piston and injection piston rod descend, the anti-leak rod, under the action of a strong spring, keeps the hemispherical anti-leak head tightly against the inner wall of the hemispherical outlet. The descent of the injection piston squeezes the essence inside the injection cylinder, which pushes the hemispherical anti-leak head downward and sprays it onto the mask through the gap between the hemispherical outlet and the hemispherical anti-leak head. This allows the essence to be sprayed out in a dispersed manner, making it better absorbed by the mask.

[0024] After the irrigation is completed, the cylinder push rod drives the force transmission rod to rise, which in turn drives the injection piston rod to rise. Under the action of the strong spring, the anti-leak rod keeps the hemispherical anti-leak head in close contact with the inner wall of the hemispherical discharge port. This allows the liquid adhering to the inside of the injection cylinder to flow out through the hemispherical discharge port and leak to the outside of the equipment, preventing pollution of the equipment and the external environment.

[0025] When the injection piston rises, the hemispherical anti-leak head blocks the hemispherical discharge port, reducing the pressure inside the injection cylinder. When the injection piston rises higher than the inlet, the essence will fill the essence storage tank under atmospheric pressure and be automatically injected into the injection cylinder through the inlet pipe, achieving automatic feeding without the need for a pump, thus saving the company's resources.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0029] Reference Figure 1-5An injection device for facial mask essence includes an injection device and a base 1. The injection device includes an infusion structure, a power structure, and an anti-drip structure. The infusion structure includes an essence storage tank 17, an inlet pipe 21, and an injection cylinder 5. The power structure includes a cylinder 22, a cylinder push rod 23, and a force transmission rod 24. The anti-drip structure includes an anti-leakage rod 8, a hemispherical outlet 13, a hemispherical anti-leakage head 14, and an injection piston rod 15.

[0030] During operation, the cylinder 22 is activated, which drives the transmission rod 24 to descend via the cylinder push rod 23. The descent of the transmission rod 24 drives the injection piston 6 to descend along the inner side of the injection cylinder 5 via the injection piston rod 15. When the injection piston 6 and the injection piston rod 15 descend, the anti-leakage rod 8, under the action of the strong spring 9, keeps the hemispherical anti-leakage head 14 in close contact with the inner wall of the hemispherical outlet 13. The descent of the injection piston 6 squeezes the essence inside the injection cylinder 5, which pushes the hemispherical anti-leakage head 14 downward and sprays it onto the mask through the gap between the hemispherical outlet 13 and the hemispherical anti-leakage head 14. This allows the essence to be sprayed out in a dispersed manner, making it better absorbed by the mask.

[0031] After the irrigation is completed, the cylinder 22 drives the force transmission rod 24 through the cylinder push rod 23 to rise, and drives the injection piston 6 to rise through the injection piston rod 15. Under the action of the strong spring 9, the anti-leakage rod 8 keeps the hemispherical anti-leakage head 14 in close contact with the inner wall of the hemispherical discharge port 13, so that the liquid attached inside the injection cylinder 5 can flow out through the hemispherical discharge port 13 and leak to the outside of the equipment, which can prevent the equipment and the external environment from being contaminated.

[0032] When the injection piston 6 rises, the hemispherical anti-leak head 14 blocks the hemispherical outlet 13, reducing the internal pressure of the injection cylinder 5. When the injection piston 6 rises higher than the inlet 12, the essence will fill the essence storage tank 17 under atmospheric pressure and be automatically injected into the injection cylinder 5 through the inlet pipe 21, achieving automatic feeding without the need for a pump, thus saving the company's resources.

[0033] An injection piston 6 slides inside the injection cylinder 5. An injection piston rod 15 is fixedly connected to the central axis above the injection piston 6. A leak-proof rod sliding cavity 7 is formed on the inner side of the injection piston 6 and the injection piston rod 15 along the central axis. A leak-proof rod piston 10 is slidably connected to the inner side of the leak-proof rod sliding cavity 7. A leak-proof rod 8 is fixedly connected below the leak-proof rod piston 10. A hemispherical leak-proof head 14 is fixedly connected below the leak-proof rod 8. A strong spring 9 is fixedly connected below the leak-proof rod piston 10. The inner side of the strong spring 9 is sleeved on the outer side of the leak-proof rod 8. The injection piston 6 is fixedly connected below the strong spring 9. After the irrigation is completed, the cylinder 22 drives the force transmission rod 24 through the cylinder push rod 23 to rise, and drives the injection piston 6 to rise through the injection piston rod 15. Under the action of the strong spring 9, the anti-leakage rod 8 keeps the hemispherical anti-leakage head 14 in close contact with the inner wall of the hemispherical discharge port 13, so that the liquid attached inside the injection cylinder 5 can flow out through the hemispherical discharge port 13 and leak to the outside of the equipment, which can prevent the equipment and the external environment from being contaminated.

[0034] A back plate 2 is fixedly connected to the upper back side of the base 1. A liquid injection cylinder fixing bracket 4 is fixedly connected to the front of the back plate 2. A liquid injection cylinder 5 is fixedly connected to the inner side of the liquid injection cylinder fixing bracket 4. A hemispherical discharge port 13 is fixedly connected to the lower part of the liquid injection cylinder 5. The liquid injection cylinder 5 can be fixed by the liquid injection cylinder fixing bracket 4 to ensure the stable operation of the equipment.

[0035] A top plate 3 is fixedly connected to the top of the back plate 2. A cylinder 22 is fixedly connected to the top of the top plate 3. A cylinder push rod 23 is slidably connected to the bottom of the cylinder 22. A force transmission rod 24 is fixedly connected to the bottom of the cylinder push rod 23. A liquid injection piston rod 15 is fixedly connected to the bottom of the force transmission rod 24. This provides power for the operation of the equipment, driving the liquid injection piston 6 below the liquid injection piston rod 15 to rise or fall within the liquid injection cylinder 5.

[0036] A liquid injection piston sealing ring 16 is fixedly connected to the side of the injection piston 6, and the outer side of the liquid injection piston sealing ring 16 slides against the inner side of the injection cylinder 5. This ensures the airtightness of the injection cylinder 5 and provides power for the automatic feeding of the equipment.

[0037] An inlet plug rod 11 is fixedly connected to the upper side of the injection piston 6. The outer side of the inlet plug rod 11 is slidably connected to the inner side of the injection cylinder 5 and covers the inlet port 12 opened on the side of the injection cylinder 5. This prevents the essence from flowing into the upper part of the injection piston 6 when the injection piston 6 descends.

[0038] A through-hole 18 is provided above the anti-leakage rod piston 10. This ensures that the sliding of the anti-leakage rod piston 10 in the anti-leakage rod sliding chamber 7 is not affected by the internal air pressure.

[0039] A serum storage tank 17 is fixedly connected to the front of the back plate 2. A serum level measuring window 20 is fixedly connected to the side of the serum storage tank 17. A serum filling port 19 is opened on the top of the serum storage tank 17. A liquid inlet pipe 21 is fixedly connected to the front of the serum storage tank 17, and a liquid inlet 12 is fixedly connected to the front end of the liquid inlet pipe 21. This facilitates the supply of materials to the equipment.

[0040] The implementation principle of the embodiment of the device for injecting facial mask essence according to this application is as follows: During the operation of the device, the cylinder 22 is started, and the cylinder push rod 23 drives the force transmission rod 24 to descend. The descent of the force transmission rod 24 will drive the injection piston 6 to descend along the inner side of the injection cylinder 5 through the injection piston rod 15. When the injection piston 6 and the injection piston rod 15 descend, the anti-leakage rod 8 will keep the hemispherical anti-leakage head 14 in close contact with the inner wall of the hemispherical outlet 13 under the action of the strong spring 9. The descent of the injection piston 6 will squeeze the essence inside the injection cylinder 5. The essence will push the hemispherical anti-leakage head 14 downward and spray it onto the facial mask through the gap between the hemispherical outlet 13 and the hemispherical anti-leakage head 14. This can disperse the essence spraying out, so that the essence can be better absorbed by the facial mask.

[0041] After the irrigation is completed, the cylinder 22 drives the force transmission rod 24 through the cylinder push rod 23 to rise, and drives the injection piston 6 to rise through the injection piston rod 15. Under the action of the strong spring 9, the anti-leakage rod 8 keeps the hemispherical anti-leakage head 14 in close contact with the inner wall of the hemispherical discharge port 13, so that the liquid attached inside the injection cylinder 5 can flow out through the hemispherical discharge port 13 and leak to the outside of the equipment, which can prevent the equipment and the external environment from being contaminated.

[0042] When the injection piston 6 rises, the hemispherical anti-leak head 14 blocks the hemispherical outlet 13, reducing the internal pressure of the injection cylinder 5. When the injection piston 6 rises higher than the inlet 12, the essence will fill the essence storage tank 17 under atmospheric pressure and be automatically injected into the injection cylinder 5 through the inlet pipe 21, achieving automatic feeding without the need for a pump, thus saving the company's resources.
