A liquid cosmetic impurity filtration device

Abstract

This utility model relates to the field of filtration technology, and more particularly to a liquid cosmetic impurity filtration device. The liquid cosmetic impurity filtration device includes a barrel and a discharge pipe, etc. The discharge pipe is connected to the bottom of the barrel, and a filter cylinder is installed inside the barrel. An electric disk is installed on the filter cylinder, and a filter bag is placed inside the filter cylinder. During the downward movement of the disk, the expanding air bladder will generate a flexible downward pressing force on the filter bag, causing the liquid inside the filter bag to flow out of the filter bag more quickly under pressure. This avoids the problem in the prior art where, during liquid filtration, some liquid cosmetics are in a fluid state and therefore have a slow flow rate. If the filter bag is kept stationary during filtration, the efficiency of the liquid passing through the mesh surface of the filter bag will be slow, thus affecting the filtration of the liquid cosmetics.

Description

Technical Field

[0001] This application relates to the field of filtration technology, specifically to a liquid cosmetic impurity filtration device. Background Technology

[0002] Cosmetics refer to chemical industrial products or fine chemical products that are applied to any part of the human body surface, such as skin, hair, nails, lips, and teeth, by means of smearing, spraying, or other similar methods, for the purpose of cleansing, maintaining, beautifying, modifying or altering appearance, or correcting body odor and maintaining a good condition.

[0003] Existing Chinese patent (CN221673612U) discloses a liquid cosmetic impurity filtration device:

[0004] The system includes connecting components such as a filter cartridge, electric cylinder, drive rod, insert cylinder, compression spring, tension spring, insert rod, mounting ring, metal filter bucket, filter bag ring, filter bag, and end cap. After the liquid cosmetic enters the metal filter bucket and filter bag, the electric cylinder drives the insert rods on both sides of the mounting ring to reciprocate within the corresponding insert cylinder via the drive rod. During the left-right movement of the metal filter bucket and filter bag, the system can solve the problem of impurities blocking the filter holes in the metal filter bucket and filter bag, resulting in low filtration efficiency. It can also accelerate the flow rate and filtration speed of the liquid cosmetic, achieving a high-efficiency filtration effect. However, this method still has the following drawbacks:

[0005] Because some liquid cosmetics are fluid, their flow rate is slow. Simply moving the filter bag left and right is not enough to allow the liquid to pass through the mesh on the surface of the filter bag, thus affecting the filtration speed of the liquid cosmetics. In addition, it is difficult to scrape off stubborn impurities attached to the inner wall of the filter bag using the above method. As a result, with prolonged use, more and more stubborn impurities will adhere to the inner wall of the filter bag. If these impurities are not treated in time, they will affect the efficiency of the filter bag in filtering liquids. Utility Model Content

[0006] In order to solve the problems existing in the prior art, the purpose of this application is to provide a liquid cosmetic impurity filtration device.

[0007] The liquid cosmetic impurity filtration device described in this application includes a barrel and a discharge pipe, characterized in that the bottom of the barrel is connected to the discharge pipe and a filter cylinder is installed inside the barrel.

[0008] An electromagnet is installed on the filter cartridge, a filter bag is installed inside the filter cartridge, a counterweight plate is installed at the bottom of the filter bag, a push rod is fixedly connected to the barrel, a disc is fixedly connected to the telescopic end of the push rod, a storage cavity is opened in the disc, an air bladder is provided on the disc, and a first telescopic hose is connected to the disc, which penetrates the filter cartridge.

[0009] Furthermore, it is particularly preferred that a fixing ring is fixedly connected to the disc, a ventilation channel is opened inside the fixing ring, multiple air outlet pipes are connected to the fixing ring, and a second telescopic hose is connected to the fixing ring, the second telescopic hose passing through the filter cartridge.

[0010] Furthermore, it is particularly preferred that the air outlet pipe is configured as a frustum shape.

[0011] Furthermore, it is particularly preferred that a motor is installed on the barrel, a spur gear is fixedly connected to the output shaft of the motor, a gear ring that meshes with the spur gear is rotatably connected to the filter cylinder, a fixing plate is fixedly connected to the gear ring, an elastic telescopic plate is inserted into the fixing plate, and a scraper that acts on the filter bag is fixedly connected to the telescopic end of the elastic telescopic plate, and the scraper is provided with a scraping edge.

[0012] Furthermore, it is particularly preferred that the scraper bar has a groove.

[0013] The liquid cosmetic impurity filtration device described in this application has the following advantages:

[0014] During the downward movement of the disc, the expanding air bladder will exert a flexible downward pressing force on the filter bag, which will accelerate the outflow of the liquid from the filter bag after the liquid is subjected to pressure. This avoids the problem in the prior art where the filter bag is in a fluid state and therefore has a slow flow rate. If the filter bag is kept stationary during filtration, the efficiency of the liquid passing through the mesh on the surface of the filter bag will be slow, thus affecting the filtration of the liquid.

[0015] The air blown out by the air tube will cause the liquid inside the tank to form a water flow. This water flow will impact the filter bag, causing impurities attached to the inner wall of the filter bag to be washed off. This will prevent impurities from clogging the mesh of the filter bag and reducing the filtration efficiency of the liquid.

[0016] The scraping edge will remove stubborn impurities adhering to the inner wall of the filter bag, thereby further ensuring the cleanliness of the inner wall of the filter bag. This prevents the filter bag from accumulating more and more stubborn impurities over a long period of use, which would affect the efficiency of the filter bag in filtering liquid if not treated in time.

[0017] After the impurities are scraped off, as the scraper rotates, the scraped impurities will enter the groove, thus collecting the impurities and preventing them from flowing around inside the filter bag, which would cause them to re-adhere to the filter bag during subsequent filtration.

Detailed Implementation

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example

[0028] A liquid cosmetic impurity filtration device, such as Figure 1-7 As shown, it includes a barrel body 1 and a discharge pipe 2, characterized in that the bottom of the barrel body 1 is connected to the discharge pipe 2, and a filter cylinder 3 is installed inside the barrel body 1.

[0029] A magnetic disk 31 is installed on the filter cartridge 3. A filter bag 4 is provided inside the filter cartridge 3. A counterweight plate 41 is provided at the bottom of the filter bag 4. A push rod 5 is fixedly connected to the barrel body 1. A disc 6 is fixedly connected to the telescopic end of the push rod 5. A storage cavity is opened in the disc 6. An air bladder part 61 is provided on the disc 6. A first telescopic hose 7 is connected to the disc 6. The first telescopic hose 7 passes through the filter cartridge 3.

[0030] A fixing ring 8 is fixedly connected to the disc 6. A ventilation channel is opened inside the fixing ring 8. Multiple air outlet pipes 9 are connected to the fixing ring 8. A second telescopic hose 10 is connected to the fixing ring 8. The second telescopic hose 10 passes through the filter cartridge 3.

[0031] The air outlet pipe 9 is designed in the shape of a frustum.

[0032] A motor 11 is installed on the barrel 1. A spur gear 12 is fixedly connected to the output shaft of the motor 11. A gear ring 13 that meshes with the spur gear 12 is rotatably connected to the filter cylinder 3. A fixing plate 14 is fixedly connected to the gear ring 13. An elastic telescopic plate 15 is inserted into the fixing plate 14. A scraper 16 that acts on the filter bag 4 is fixedly connected to the telescopic end of the elastic telescopic plate 15. The scraper 16 is provided with a scraping edge 16a.

[0033] The scraper 16 has a groove 16b.

[0034] When using this liquid cosmetic impurity filtration device, the first telescopic hose 7 and the second telescopic hose 10 are both connected to the pump through the external delivery hose.

[0035] Next, the staff delivers the liquid cosmetics to be filtered into filter bag 4. The liquid then passes through filter bag 4 and filter cartridge 3 before falling into tank 1. Impurities in the liquid are intercepted by filter bag 4. During the liquid filtration process, as liquid is continuously input, the liquid level in tank 1 gradually rises until it contacts the lower surface of disc 6. At this point, the liquid delivery is stopped. Then, an external pump is controlled to deliver air into the storage cavity inside disc 6 through delivery hose and first telescopic hose 7. The air then forces airbag 61 to inflate, and the inflated airbag 61 contacts filter bag 4, squeezing it and causing the squeezed part of filter bag 4 to become concave. Figure 7 As shown, the control push rod 5 then moves the disc 6 downward, and the fixing ring 8 and the air outlet pipe 9 move synchronously with the disc 6. The first telescopic hose 7 and the second telescopic hose 10 are stretched. Then, during the downward movement of the disc 6, the expanded air bladder 61 will produce a flexible downward pressing force on the filter bag 4, so that the liquid in the filter bag 4 will be under pressure and the liquid will flow out of the filter bag 4 more quickly. This avoids the situation in the prior art where the filter bag 4 is in a fluid state when filtering liquid, so the flow rate is slow. If it is kept in a static state for filtration, the efficiency of the liquid passing through the mesh on the surface of the filter bag 4 will be slow, thus affecting the filtration of liquid cosmetics.

[0036] Meanwhile, during the downward movement of the fixed ring 8, the external pump is controlled to deliver air into the fixed ring 8 through the delivery hose and the second telescopic hose 10 in sequence. The air is then blown out through the air outlet pipe 9. As the fixed ring 8 moves downward, the fixed ring 8 and the air outlet pipe 9 will enter the liquid in the tank 1. Therefore, the air blown out by the air outlet pipe 9 will cause the liquid in the tank 1 to form a water flow. The water flow will impact the filter bag 4, causing the impurities attached to the inner wall of the filter bag 4 to be washed off. This will prevent the impurities from clogging the mesh on the filter bag 4 and reducing the filtration efficiency of the liquid. At the same time, since the air outlet pipe 9 is set in a frustum shape, the air velocity will increase when the air is blown out through the frustum-shaped air outlet pipe 9. This will make the water flow more rapid and cause a greater impact on the filter bag 4, thereby improving the cleaning effect on the impurities on the inner wall of the filter bag 4.

[0037] It should be noted that during the upward repositioning process of the disc 6, the expanded air bladder 61 is still in a state of compression on the filter bag 4, and the electric disk 31 attracts the counterweight disk 41. Therefore, when the disc 6 moves upward, the expanded air bladder 61 will not lift the filter bag 4. Furthermore, as the disc 6 moves upward, the expanded air bladder 61 can still exert a compressive force on the liquid inside the filter bag 4.

[0038] It is explained here that when the inflated air bladder 61 squeezes the filter bag 4, the concave part of the filter bag 4 will force the scraper 16 to move toward the center of the barrel 1. The moving scraper 16 will then drive the telescopic end of the elastic telescopic plate 15 to extend, thereby avoiding the situation where the air bladder 61 would not be able to squeeze the filter bag 4 if the scraper 16 were fixed.

[0039] Next, when the airbag 61 is no longer in contact with the filter bag 4, taking the view from top to bottom as a reference, the control motor 11 causes the spur gear 12 to rotate clockwise, and the spur gear 12 causes the transmission gear ring 13 to rotate counterclockwise. The fixed plate 14, the elastic telescopic plate 15 and the scraper 16 will rotate synchronously with the transmission gear ring 13. During this process, since the scraping edge 16a on the scraper 16 is in contact with the inner wall of the filter bag 4, the scraping edge 16a will scrape off the more stubborn impurities attached to the inner wall of the filter bag 4, thereby further ensuring the cleanliness of the inner wall of the filter bag 4. This prevents the filter bag 4 from accumulating more and more stubborn impurities on its inner wall over a long period of use. If these impurities are not treated in time, the efficiency of the filter bag 4 in filtering liquid will be affected.

[0040] Then, after the impurities are scraped off, as the scraper 16 rotates, the scraped impurities will enter the groove 16b, thereby collecting the impurities through the groove 16b, thus preventing the scraped impurities from flowing around in the filter bag 4, which would cause the scraped impurities to re-adhere to the filter bag 4 during subsequent filtration.

[0041] Next, when the filter bag 4 needs to be cleaned after the liquid has been filtered, the staff first removes the elastic telescopic plate 15 and the parts connected to it from the fixed plate 14, then controls the power to turn off the electric disk 31 so that the electric disk 31 does not generate magnetic attraction force on the counterweight plate 41, and then the staff can lift the filter bag 4 out of the filter cylinder 3.
