[0097] S5, the driving mechanism drives the scraper plate 11 to move downward, and scrapes the impurities filtered out from the top of the filter element 9 into the receiving cover 10.

[0098] The present invention provides a wet wipes liquid dripping system and process. When dripping essence liquid, first, the dripping pump 4 injects the essence liquid in the silo 1 into the main dripping pipe 5 and the dripping pipe 6 through the external discharge pipe 3, and drips downward onto the non-woven fabric through the dripping hole; the excess essence liquid drips from the bottom of the non-woven fabric and drips into the collecting cover 7; the essence liquid in the collecting cover 7 flows downward through the collecting port 8, and flows downward along the top of the filter element 9, and impurities in the essence liquid are filtered out during the flow process. After passing through the filter element 9, the essence liquid drips into the liquid receiving dish 12; the essence liquid in the liquid receiving dish 12 flows into the silo 1 under the action of gravity for recycling; the driving mechanism drives the scraper plate 11 to move downward, and scrapes the impurities filtered out from the top of the filter element 9 into the receiving cover 10. Although the receiving cover 10 needs to be replaced or cleaned manually by workers regularly, in this application, since the receiving cover 10 is not needed to filter the essence, even if there is a lot of impurities inside, it will not affect the normal filtration of the filter element 9, so the cleaning efficiency can be greatly reduced; at the same time, since the filtering area of ​​the filter element 9 is large, the filtering effect can still be guaranteed.

[0099] When the non-woven fabric passes over the top of the centralizing cover 7, the non-woven fabric can be suspended in the air or supported by a porous plate or multiple parallel rods. At the same time, in actual use, the liquid adding tube 2 will continue to add new essence into the silo 1 to ensure that the essence in the silo 1 is sufficient; and when in use, there is an air inlet pipe at the top of the silo 1 to balance the air pressure inside and outside the silo 1. It should also be understood that the main dropper 5, the dropper 6, etc. (not exhaustive) in this application all have a frame to support them, and at the same time, an opening for replacing the receiving cover 10 is opened on the frame.

[0100] When the essence in the liquid receiving dish 12 is small, the elastic force of the first elastic member 18 makes the height of the liquid receiving dish 12 higher. Although the floating ball 37 (which has a large mass and a large volume, so that it can float and can also drive the linkage rod 39 to move through the unlocking plate 38) is located at the bottom of the liquid receiving dish 12, the liquid receiving dish 12 is high, so it does not affect the movement of the linkage rod 39, etc.; at the same time, the first opening and closing plate 22 is attached to the top of the magnetic body 24, and the magnetic body 24 fixes the angle of the first opening and closing plate 22 and the second opening and closing plate 23, and keeps the outflow tube 20 in a closed state (it does not affect the essence flowing down the periphery of the first opening and closing plate 22 and the second opening and closing plate 23), so the essence in the liquid receiving dish 12 can be enriched. At the same time, the free end of the telescopic body 50 abuts against the outer side of the unlocking member 53.

[0101] As the amount of essence in the liquid receiving dish 12 increases, the first elastic member 18 is gradually compressed, causing the height of the liquid receiving dish 12 to gradually decrease. During the lowering process, although the second opening and closing plate 23 is subjected to a greater pressure of essence (F=P*S), the first opening and closing plate 22 can still remain stationary due to the presence of the magnetic body 24. At the same time, when the telescopic body 50 drops below the unlocking member 53, the elastic force of the third elastic member 51 causes the telescopic body 50 to move outward. As the amount of essence increases, the height of the floating ball 37 relative to the liquid receiving dish 12 increases.

[0102] As the amount of essence in the liquid receiving dish 12 continues to increase, the buckle plate 33 on the outside of the liquid receiving dish 12 will contact the upper side of the inclined positioning rod 32 during the descent process, and drive the positioning rod 32 to move away from the liquid receiving dish 12, while compressing the second elastic member 31. During the descent process of the telescopic body 50, the lower side of the free end of the telescopic body 50 will contact the top of the linkage seat 45. Since the bottom of the outer side of the telescopic body 50 is inclined, the telescopic body 50 will move toward the telescopic hole 49 again during the descent process, and compress the third elastic member 51.

[0103] When the height of the liquid receiving dish 12 reaches the node of the lowest state, the buckle plate 33 just passes the bottom of the positioning rod 32, and the positioning rod 32 quickly rebounds under the elastic force of the second elastic member 31, and the bottom of the positioning rod 32 is buckled on the top of the buckle plate 33. This process is carried out very quickly, and the position of the liquid receiving dish 12 hardly changes; and at this time, the hinged rod 30 is in the setting state, and the bottom of the positioning rod 32 is horizontally attached to the top of the buckle plate 33, so the positioning rod 32 can stably buckle the position of the buckle plate 33, and also fix the position of the liquid receiving dish 12; at the same time, at this node, the telescopic body 50 is just aligned with the linkage hole 46, and under the elastic force of the third elastic member 51, the free end of the telescopic body 50 is inserted into the linkage hole 46; at the same time, the opening rod 25 lifts the bottom of the first opening and closing plate 22 upward (it can be understood that before the liquid receiving dish 12 reaches the lowest height, the opening rod 25 is very close to or just in contact with the bottom of the first opening and closing plate 22, and then when the liquid receiving dish 12 reaches When the liquid receiving dish 12 reaches the lowest point, the opening rod 25 just lifts up the first opening and closing plate 22, and separates the first opening and closing plate 22 from the magnetic body 24; before the height of the liquid receiving dish 12 reaches the lowest point, the first opening and closing plate 22 and the second opening and closing plate 23 are in a very close equilibrium state, that is, the liquid pressure on the second opening and closing plate 23 is slightly smaller than the liquid pressure on the first opening and closing plate 22 and the sum of the forces between the second opening and closing plate 23 and the magnetic body 24. Therefore, when the opening rod 25 lifts up the first opening and closing plate 22, Under the action of the essence liquid pressure, the second opening and closing plate 23 swings downward, while the first opening and closing plate 22 swings upward. During the swinging process, since the distance between the first opening and closing plate 22 and the magnetic body 24 becomes larger and larger, the swing amplitude of the first opening and closing plate 22 and the second opening and closing plate 23 also becomes larger and larger, until the lower side of the second opening and closing plate 23 hits the end column 26. At this time, the outflow tube 20 is in a larger open state, and the essence liquid in the liquid receiving dish 12 can flow into the silo 1 relatively quickly.

[0104] As the liquid level of the essence in the liquid receiving dish 12 decreases, the heights of the floating ball 37, the synchronous member 36 and the unlocking plate 38 all decrease. When they decrease to a certain height (for example, when the essence in the liquid receiving dish 12 flows out completely, the floating ball 37 contacts the bottom of the inner cavity of the liquid receiving dish 12), the unlocking plate 38 contacts the top of the linkage rod 39 and presses the linkage rod 39 downward. At this time, the linkage rod 39 drives the two hinged rods 30 to move, so that the hinged rod 30 is separated from the buckle plate 33. At this time, under the elastic force of the first elastic member 18, the liquid receiving dish 12 is quickly raised. At the same time, since the free end of the telescopic body 50 is inserted into the linkage hole 46, the telescopic body 50 raises the linkage seat 45, the lifting member 43 and the lifting gear 44 upward. The inner side of the lifting gear 44 meshes with the fixed rack 42, and the outer side meshes with the movable rack 56, so when the lifting gear 44 moves upward, the movable rack 56, the vertical cylinder 55 and the horizontal rod 57 can be raised. At the same time, the horizontal rod 57 can pull the guide member 63 downward through the traction cable 64, and the two guide members 63 drive the scraper plate 11 to scrape and clean the upper side of the filter element 9 during the downward movement. In addition, the lifting gear 44, the fixed rack 42 and the movable rack 56 make it possible to make the movable range of the guide member 63 larger even if the height of the liquid receiving dish 12 is small, and the top of the entire filter element 9 can be hung.

[0105] When the liquid receiving dish 12 is raised, the unlocking member 53 will be inserted into the unlocking port 47 and act on the outer side of the free end of the telescopic member. Since the bottom of the unlocking member 53 is inclined, it can drive the telescopic body 50 to move toward the telescopic hole 49 until the telescopic body 50 is separated from the linkage seat 45; wherein the telescopic body 50 is separated from the linkage seat 45 before the liquid receiving dish 12 is raised to the highest height. When the guide member 63 moves downward, the fixed reset tooth body 71 causes the first reset gear 67 to rotate, and at the same time, it drives the second reset gear 68 to rotate, and the second reset gear 68 can drive the third reset gear 69 and the second reset rod to rotate, and at the same time drives the reset spring 72 to further undergo elastic deformation, that is, when the guide member 63 moves downward, the elastic potential energy of the reset spring 72 is further increased. When the telescopic body 50 is separated from the linkage seat 45, the scraper plate 11 moves upward under the elastic force of the reset spring 72 until the guide member 63 moves to the top of the guide groove 62, wherein the reset spring 72 still has the elastic potential energy to drive the guide member 63 upward.

[0106] Before the liquid receiving dish 12 is raised to the highest height, the closing rod 28 will contact the top of the first opening and closing plate 22 and drive the first opening and closing plate 22 to swing downward. When the liquid receiving dish 12 is raised to the highest height, the first opening and closing plate 22 is attached to the top of the magnetic body 24, and the first opening and closing plate 22 is also reset. According to the actual situation, an anti-slip cable can be installed between the inner wall of the support tube 16 and the bottom of the liquid receiving dish 12. When the liquid receiving dish 12 is raised to the highest height, the anti-slip cable is just stretched straight to prevent the inertia of the liquid receiving dish 12 from affecting the first opening and closing plate 22 and the closing rod 28. At the same time, there are rotating steel columns at the bottom of the closing rod 28 and the top of the opening rod 25 to reduce resistance and wear. When the liquid receiving dish 12 is raised to the highest height, the positioning rod 32, the floating ball 37, the telescopic body 50, etc. are all reset, waiting for the next cycle of activities.

[0107] In the present application, the filtration of the essence and the self-cleaning of the filter 9 do not need to be manually performed by workers, nor do they need to be realized by structures such as motors. Instead, the gravity of the refluxed essence is used to automatically clean the filter 9 periodically, which saves costs and prevents program errors. In actual use, workers need to regularly pull the receiving cover 10 out of the support part 15 and clean it, and the cycle can be long and the operation is relatively convenient. At the same time, since the receiving cover 10 is porous, even if the essence enters the receiving cover 10, it can automatically drip into the receiving dish 12. Moreover, during filtration, the scraper plate 11 is located above the essence; when scraping the impurities on the filter element 9 downward, the scraper plate 11 also moves faster because the liquid receiving dish 12 rises faster, and after the liquid receiving dish 12 reaches the lowest height, it can also rise quickly under the elastic force of the reset spring 72, so the impurities upstream of the scraper plate 11 are very small and can be ignored or only need to be manually cleaned once in a long time, and the impact on the overall use can be ignored. The limit frame 13 can limit the dripping essence and the essence driven by the scraper plate 11.

[0108] In another embodiment, the cross section of the inner cavity of the outflow tube 20 is circular, and a vertical piston rod is provided on the inner wall of the bottom of the inflow tube 19, and a piston plate is provided on the top of the piston rod; before the height of the liquid receiving dish 12 reaches the lowest point, the side wall of the piston plate is in contact with the inner wall of the outflow tube 20, so the essence can be concentrated in the liquid receiving dish 12; then when the height of the liquid receiving dish 12 just reaches the lowest height, the piston plate is just higher than the outflow tube 20, so the outflow tube 20 can be opened at this time, so that the essence in the liquid receiving dish 12 can automatically flow into the silo 1. Its flow rate is slower than that of the first opening and closing plate 22 and the second opening and closing plate 23 structure, so the period of the liquid receiving dish 12 rising and resetting is also relatively long.

[0109] In another embodiment, two extension frames are provided at the upstream end of the limit frame 13, and a reset wheel is connected to the free end of the extension frame for vertical rotation, and a reset cable is provided to move around the reset wheel; one end of the reset cable is connected to the guide member 63, and a reset ball is suspended at the other end. When the guide member 63 moves downward, the reset ball is lifted; when the telescopic body 50 escapes from the linkage hole 46, the gravity of the reset ball causes the guide member 63 to move upward. The outer wall of the reset wheel has a groove for limiting the reset cable, and a fixed anti-drop cover is provided above the reset wheel, which can limit the reset cable and ensure its stable use.

[0110] It should also be noted that all the "settings" and similar descriptive words in this application (especially the specification) express that there is or exists a connection relationship between two structures, but there is no excessive limitation on the specific means by which the two are connected, and it is usually a conventional connection means, that is, it should be understood that the means are prior art and there is no need for excessive elaboration. For example, "n is set on m" only expresses that there is n structure on m structure, and the two are specifically connected by welding, riveting, adhesive connection or integral molding, which are all within the protection scope of this application; for another example, "y is rotatably set on x" only expresses that y and x can rotate relative to each other, and whether the two are connected by bearing rotation, or y directly passes through x and is connected to x rotationally, or other feasible methods, are all within the protection scope of this application.

[0111] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
