Currently, some liquid cosmetics usually require the use of filtering devices to filter the semi-finished liquid cosmetics during the production process to reduce impurities in the liquid cosmetics and achieve the purpose of liquid cosmetics production.

[0003] Existing cosmetic filtering devices often have multiple sets of cosmetic filter screens installed in the middle of a cylindrical tank to filter through the screen. Its main purpose is to remove impurities, particulate matter and microorganisms in liquids or powders to ensure the quality and safety of the final product.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0022] The following describes an embodiment of the present invention based on its overall structure.

[0023] A cosmetics filtering device, such as Figure 1-5As shown, it includes a tank body 1, a pressure plate 19, a sealing plate 13, a bottom plate 11, an opening and closing mechanism, a filter plate 7, and a driving device. A accommodating chamber is provided in the tank body 1, and a top plate 2 is provided at the top of the tank body 1. The bottom plate 11 is provided in the accommodating chamber and is located below the sealing plate 13. The position of the bottom plate 11 remains fixed. The driving device includes a base 14, a motor 6, a rotating rod 18, a bidirectional screw rod 16, and a fixed rod 8. The fixed rod 8 is provided in multiple groups, and the top ends of the fixed rods 8 are all fixed to the bottom ends of the top plates 2, and the bottom ends of the fixed rods 8 are all fixed to two groups of bottom plates 11. The opening and closing mechanism includes a spring 10, which is sleeved on the fixed rod 8 and is located between the sealing plate 13 and the bottom plate 11. A pressure plate 19 is movably mounted within the accommodating chamber, with its periphery abutting against the chamber's sidewalls. A flow hole 9 is provided in the center of the pressure plate 19, through which a securing rod passes to radially constrain the pressure plate 19 and prevent rotation. A sealing plate 13 is positioned within the accommodating chamber, below the pressure plate 19. The dimensions of the sealing plate 13 are larger than those of the flow hole 9. A scraper 12 is mounted on the bottom plate. A filter plate 7 is positioned within the accommodating chamber, below the bottom plate 11. The periphery of the filter plate abuts against the chamber's sidewalls, with the scraper 12 resting against the upper surface of the sealing plate 13. The base 14 is arranged at the bottom end of the tank body 1, the motor 6 is arranged on the base 14, the rotating rod 18 is rotatably set on the base 14, one end of the rotating rod 18 is connected to the output end of the motor 6, and the other end of the rotating rod 18 extends into the accommodating cavity and is connected to the filter plate 7. The bidirectional screw rod 16 is located in the accommodating cavity, one end of the bidirectional screw rod 16 is rotatably set on the tank body 1, and the other end of the bidirectional screw rod 16 is connected to the rotating rod 18. The pressure plate 19 and the filter plate 7 are both sleeved on the bidirectional screw rod 16.

[0024] When the motor 6 drives the pressure plate 19 via the bidirectional screw 16 to press the sealing plate 13 downward within the accommodating chamber, the spring 10 acts to force the sealing plate 13 tightly against the pressure plate 19, thereby closing the flow hole 9 on the pressure plate 19. This prevents some liquid cosmetics from flowing out of the flow hole 9 when the pressure plate 19 pressurizes the liquid cosmetics inside. When the motor 6 drives the pressure plate 19 upward within the accommodating chamber via the bidirectional screw 16 until it no longer presses the sealing plate 13, the spring 10 returns to its original position, and the sealing plate 13 moves away from the flow hole 9. In addition, the drive device also simultaneously drives the filter plate 7 to rotate about the central axis of the accommodating chamber, so that the scraper 12 can clean impurities accumulated on the filter plate 7 and prevent the filter plate 7 from clogging.

[0025] In this embodiment, the base 14 and the motor 6 can be fixed by fasteners, and the fixing rod 8 and the bottom plate 11 can be fixed by welding, so as to ensure that the sealing plate 13 does not become loose during movement. A slight gap can be provided between the edge of the pressure plate 19 and the interior of the tank body 1 to prevent the pressure plate 19 from having a large friction with the interior of the tank body 1, resulting in an inability to move up and down.

[0026] In some examples, a limit ring is provided between the spring 10 and the sealing plate 13 .

[0027] In some examples, such as Figure 1 and Figure 2 As shown, a bracket 3 is provided on the outside of the tank body 1, and the tank body 1 and the bracket 3 are fixedly connected by welding.

[0028] In some examples, such as Figure 1 and Figure 2 As shown, a feed port 4 is provided on the outside of the tank body 1 , and the height of the feed port 4 is higher than the pressure plate 19 . A discharge port 5 is provided on the outside of the tank body 1 , and a valve is provided inside the discharge port 5 .

[0029] In some examples, such as Figure 5 As shown, a water slip ring 17 is provided between the rotating rod 18 and the base 14 , and a fixing ring 15 is provided on the outside of the rotating rod 18 .

[0030] The working principle of this utility model is as follows:

[0031] First, turn on the power supply and inject the liquid cosmetics to be filtered from the outside through the feed port 4 via the external water pump. The injected liquid cosmetics will enter the upper part of the pressure plate 19 inside the tank body 1 through the feed port 4 and slowly flow into the tank body 1 from the two groups of flow holes 9 provided on the pressure plate 19.

[0032] At the same time, the internal motor 6 is controlled to start by the external control device. When the motor 6 is started, the motor 6 drives the rotating rod 18 to rotate. The rotation of the rotating rod 18 synchronously drives the bidirectional screw rod 16 connected to the top and the filter plate 7 arranged on the outside to rotate. When the filter plate 7 rotates, it will accelerate the accumulation of liquid cosmetics on the top of the filter plate 7, and to a certain extent prevent the filter holes of the filter plate 7 from being blocked, causing the subsequent liquid cosmetics to be unable to be filtered, affecting the overall rate; when the bidirectional screw rod 16 rotates, the pressure plate 19 arranged on the outside will move along the bidirectional screw rod 1 6 makes vertical reciprocating motion. When the pressing plate 19 is pressed down by the bidirectional screw 16, it squeezes the two sets of sealing plates 13 located below the pressing plate 19. When the pressing plate 19 squeezes the sealing plates 13 downward, the spring 10 acts to make the sealing plates 13 tightly fit on the pressing plate 19. The fit sealing plates 13 block the flow holes 9 on the pressing plate 19, preventing some liquid cosmetics from flowing out of the flow holes 9 when the pressing plate 19 pressurizes the liquid cosmetics inside, resulting in the inability to accelerate the flow rate of the liquid cosmetics and accelerate the filtration.

[0033] Through the above structure, the filter plate 7 can remain in motion during the filtration process. After a long period of filtration, the filter plate 7 is not easily clogged, thereby affecting the filtration efficiency. The pressing plate 19 and the sealing plate 13 can also be used to pressurize the semi-finished liquid cosmetics to control the flow rate of the cosmetics themselves and improve the overall filtration efficiency of the liquid cosmetics.

[0034] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
