Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a liquid cosmetic filtration device. Background Technology

[0002] Liquid cosmetics refer to cosmetics that exist in liquid or semi-liquid form. They are made by using water, oil, alcohol, or other solvents as a base in the formula, combined with active ingredients, emulsifiers, preservatives, etc. Common liquid cosmetics include toners, serums, lotions, perfumes, makeup removers, sunscreen sprays, etc. Raw materials and synthetic ingredients, such as plant extracts, may contain particulate matter or undissolved solid residues, which can affect the quality of liquid cosmetics and require filtration.

[0003] A Chinese patent (publication number CN215609733U) was found to be a liquid cosmetic impurity filtration device. This patent technology includes a filter box and a fine filter screen. The fine filter screen is horizontally fixed at the bottom inside the filter box. A coarse filter screen is horizontally fixed inside the filter box above the fine filter screen. The coarse filter screen has a cavity inside, and an electric heating wire is embedded and fixed inside the cavity, filling the cavity of the coarse filter screen. An opening is provided on the rear surface of the filter box above the fine filter screen, communicating with the interior of the filter box. A cover plate is attached and fixed to the surface of the filter box at the rear end of the opening. This invention, by horizontally fixing a coarse filter screen inside the filter box above the fine filter screen and filling the cavity of the coarse filter screen with an electric heating wire, allows liquid cosmetics to be filtered first. The cosmetics, when passing through the coarse filter screen, are heated to melt any solidified clumps and then fall to the fine filter screen below for filtration. This avoids waste of cosmetics and prevents the fine filter screen from being clogged by clumps of cosmetics.

[0004] This patented technology has the advantage of filtering liquid cosmetics during use, but it still has shortcomings. After filtering, solid particles remain on the filter components, which can cause blockages over time, affecting the filtration efficiency and requiring regular cleaning, thus increasing cleaning costs. Therefore, we propose a liquid cosmetic filtration device to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a liquid cosmetic filtration device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a liquid cosmetic filtration device, comprising a barrel, a motor, a filter cartridge, a ring tube, and an installation tube. A motor is mounted above the barrel, and a filter cartridge is located inside the lower end of the barrel. A rotating shaft, rotatably mounted inside the barrel and filter cartridge, is located at the output end of the motor. Multiple sets of installation tubes arranged in a circular array and open at both ends are sleeved on the outer side of the filter cartridge. A suction pump and a pressurizing pump are mounted on the lower end of the barrel. A support ring one and a support ring two are respectively installed inside the installation tubes. A valve core one and a valve core two are respectively installed inside the support ring one and support ring two. A valve spring one and a valve spring two are respectively installed at one end of the valve core one and valve core two. A valve ring one connected to one end of the valve spring one is installed on the inner wall of the installation tube. A valve ring two connected to one end of the valve spring two is installed on the inner wall of the installation tube. Longitudinal and annular retaining rings are sleeved on the outer side of the installation tube. A ring tube is located inside the upper end of the barrel.

[0007] Preferably, one end of the mounting tube is provided with a nozzle corresponding to the inner wall of the retaining ring, and the inner diameter of the nozzle is smaller than the inner diameter of the mounting tube. When the nozzle outputs liquid, the liquid transported from the large channel to the small channel is pressurized, causing the liquid to be ejected.

[0008] Preferably, the connection end between the mounting tube and the nozzle is provided with a conical surface, and the inner wall radius of the conical surface gradually increases away from the nozzle. When the liquid inside the mounting tube is transported to the nozzle, the conical surface guides the liquid flow, thus achieving a guiding effect during the liquid transport process.

[0009] Preferably, the mounting tubes are connected to each other via connecting tubes, and the annular tube is connected to the mounting tubes via connecting tubes. The suction force or pressure acting on the inner wall of the mounting tube is applied to other mounting tubes through the connecting tubes.

[0010] Preferably, one end of the mounting tube is provided with a suction shroud corresponding to the outer wall of the filter cartridge. The suction force of the mounting tube is applied to the outer wall of the filter cartridge through the suction shroud.

[0011] Preferably, the lower inner wall of the barrel is provided with a flow guiding surface, and a fixing rod connected to the inner wall of the barrel at its lower end passes through the baffle rings. A discharge pipe controlled by a valve is provided at the lower end of the barrel. The liquid inside the barrel is guided by the flow guiding surface, the baffle rings are fixed to the outside of the filter cartridge by the fixing rod, the liquid is output through the discharge pipe, and the opening and closing of the discharge pipe is controlled by the valve.

[0012] Preferably, the outer wall of the rotating shaft is provided with stirring rods arranged in a ring array inside the filter cylinder, and the upper outer wall of the rotating shaft is provided with side rods arranged in a ring array outside the filter cylinder. The stirring rods stir and mix the liquid inside the filter cylinder, and the side rods agitate the liquid at the inner edge of the barrel.

[0013] Preferably, a base is provided at the lower end of the barrel, and the suction pump and the pressurizing pump are connected to the ring pipe through pipes. The base supports the lower end of the barrel, the suction force of the suction pump acts on the inside of the ring pipe, and the pressure output by the pressurizing pump acts on the inside of the ring pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model filters cosmetic liquids using a filter cartridge. Incompletely dissolved raw material particles are intercepted on the outside of the filter cartridge. During use, the suction pump and the pressurizing pump operate in stages, generating intermittent suction and conveying forces inside the installation pipe. The suction force acts directly on the outer wall of the filter cartridge, and the solid shell intercepted by the outer wall of the filter cartridge is drawn into the installation cylinder and sprayed onto the retaining ring after pressurization. The particles break during the impact, achieving re-fusion with the cosmetic liquid, thereby cleaning the filter cartridge and avoiding clogging during continuous use. While the cosmetic liquid is effectively filtered, the intercepted raw material particles are re-fused and the filter cartridge is prevented from clogging, achieving high-efficiency use of the filtration equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, the present invention proposes a liquid cosmetic filtration device, which includes a barrel 1, a motor 2, a filter cartridge 4, a ring pipe 10 and an installation pipe 11. The motor 2 is provided above the barrel 1, the filter cartridge 4 is provided inside the lower end of the barrel 1, and the output end of the motor 2 is provided with a rotating shaft 7 that is rotatably installed inside the barrel 1 and the filter cartridge 4.

[0024] A flow guide surface 9 is provided on the inner wall of the lower end of the barrel 1, and a discharge pipe 14 controlled by a valve is provided at the lower end of the barrel 1;

[0025] The outer wall of the rotating shaft 7 is provided with stirring rods 16 arranged in a ring array and located inside the filter cylinder 4, and the upper outer wall of the rotating shaft 7 is provided with side rods 8 arranged in a ring array and sleeved on the outside of the filter cylinder 4.

[0026] A base 3 is provided at the lower end of the barrel body 1;

[0027] Based on the implementation steps of Example 1: It is worth noting that, as needed, technicians can set an inlet connected to the barrel 1 at the upper end or outer wall of the barrel 1. Liquid cosmetics enter the filter cartridge 4 through the inlet of the barrel 1. The motor 2 drives the rotating shaft 7 to drive the stirring rod 16 to rotate at high speed, which forcibly stirs and mixes the liquid to prevent the active ingredients from settling or the oil from agglomerating. The pore size of the filter cartridge 4 is customized according to the requirements. When filtering cosmetic liquid, it needs to reach 10-50 microns. The filter cartridge 4 intercepts undissolved particles. The filtered clean liquid flows out from the discharge pipe 14 through the guide surface 9. The guide surface 9 at the lower end of the barrel 1 guides the liquid to quickly collect in the discharge pipe 14 to reduce residue.

[0028] like Figures 1-5As shown, compared with Embodiment 1, the liquid cosmetic filtration device proposed in this utility model further includes: multiple sets of installation tubes 11 arranged in a ring array and open at both ends are sleeved on the outside of the filter cylinder 4; a suction pump 13 and a pressurizing pump 15 are provided at the lower end of the barrel 1; support ring 17 and support ring 23 are respectively provided inside the installation tubes 11; valve core 10 and valve core 27 are respectively provided inside the support ring 17 and support ring 23; valve spring 18 and valve spring 26 are respectively provided at one end of valve core 10 and valve core 27; valve ring 19 connected to one end of valve spring 18 is provided on the inner wall of the installation tube 11; valve ring 22 connected to one end of valve spring 26 is provided on the inner wall of the installation tube 11; a retaining ring 5 arranged in a longitudinal direction and in a ring shape is sleeved on the outside of the installation tube 11; and a ring tube 10 is provided inside the upper end of the barrel 1.

[0029] One end of the mounting tube 11 is provided with a nozzle 24 corresponding to the inner wall of the retaining ring 5, and the inner diameter of the nozzle 24 is smaller than the inner diameter of the mounting tube 11.

[0030] The connection end between the mounting tube 11 and the nozzle 24 is provided with a conical surface 25, and the inner wall radius of the conical surface 25 gradually increases away from the nozzle 24;

[0031] The mounting pipes 11 are connected by a connecting pipe 12, and the ring pipe 10 is connected to the mounting pipes 11 by the connecting pipe 12.

[0032] One end of the mounting tube 11 is provided with a suction cover 21 corresponding to the outer wall of the filter cartridge 4;

[0033] A fixing rod 6, the lower end of which is connected to the inner wall of the barrel 1, passes through the retaining rings 5;

[0034] The suction pump 13 and the booster pump 15 are connected to the ring pipe 10 via pipes;

[0035] In this embodiment, the suction pump 13 is started, and a negative pressure is formed in the installation pipe 11 through the ring pipe 10 and the connecting pipe 12. The valve core 20 is opened by the valve spring 18. The particles attached to the outer wall of the filter cartridge 4 are sucked into the installation pipe 11. The suction hood 21 enhances the local suction. The pressurizing pump 15 is started, and the pressure pushes the valve core 27 to compress the valve spring 26 to open. The liquid carrying the particles is accelerated by the conical surface 25. The inner diameter is reduced, which increases the flow rate. The liquid is sprayed out at high speed from the nozzle 24 and impacts the inner wall of the baffle ring 5. The particles break when they hit the baffle ring 5 at high speed. The broken micron-sized particles flow back to the tank 1 with the liquid and are mixed and dissolved twice by the stirring rod 16 to avoid waste of raw materials. During suction, the valve core 20 is opened, the valve spring 18 is compressed, the valve core 27 is closed, and the valve spring 26 is reset to form a one-way suction channel. During pressurization, the valve core 20 is closed and the valve core 27 is opened to form a one-way injection channel to prevent pressure back leakage.

[0036] The suction pump 13 and the pressurization pump 15 operate simultaneously, seamlessly switching between filtration and cleaning to achieve continuous production. Traditional equipment requires periodic shutdowns for cleaning, affecting production capacity. The suction or pressurization frequency can be set via PLC to adapt to cosmetics of different viscosities, such as low-viscosity toners and high-viscosity serums. Particles on the surface of the filter cartridge 4 are removed in real time through a self-cleaning mechanism, avoiding manual cleaning. Particle recycling and redissolution reduce raw material loss. It filters fibrous residues in plant extracts. The self-cleaning mechanism prevents filter cartridge 4 from clogging, ensuring the permeability of high-value-added ingredients. The dynamic suction, pressurization self-cleaning, particle crushing and redissolution, and efficient stirring and guiding design solve the problems of clogging, raw material waste, and low efficiency in liquid cosmetic filtration, significantly improving production continuity and product quality.

[0037] The above specific embodiments are merely several preferred embodiments of this utility model.
