Description

Technical Field

[0001] The utility model relates to the technical field of cigarette filling, in particular to a detachable flavoring material filtering screen. Background Art

[0002] During the cigarette shred manufacturing process, tobacco leaves are added with flavoring agents. Flavoring agents primarily consist of sugars, tobacco extract, and spices. Spraying the flavoring agents evenly onto the leaves allows them to absorb the liquid, improving the aftertaste, masking unpleasant odors, enhancing the tobacco's aroma, and enhancing its physical properties. Because the flavoring agents contain a highly viscous sugar solution and contain many impurities, filtering is necessary to prevent clogging. However, in actual production, the design of the flavoring agent filter screen has inherent drawbacks: after prolonged use, debris adheres strongly to the screen, making it difficult to clean, and the internal filter is difficult to remove.

[0003] Patent document CN203235337U discloses a novel filtration device for a tobacco thread feeder. The device comprises a three-stage sedimentation filter element positioned within the feeder's filter cup. The filter element is divided into a primary, secondary, and tertiary chambers, from the inside out. Discharge holes are located on the outer walls of the tertiary chambers, and a discharge hole is located at the bottom of the feeder's filter cup. A removable bottom cover is located at the bottom of the filter element.

[0004] In this prior art, cleaning the filter cartridge requires removing the filter cartridge, removing the movable bottom cover, and then rinsing it with water. Because the movable bottom cover is located at the bottom and remains immersed in the sugar material for a long period of time during filtration, the connection between the movable bottom cover and the filter cartridge can become clogged with sugar material, making it difficult to remove and clean.

[0017] 1. In the present application, firstly, the top of the filter barrel is detachably connected to the tank body, and the top of the filter barrel will not be immersed in the sugar material and affect its disassembly, making it easy to disassemble; secondly, the bottom of the filter barrel is set to a conical structure to fix and support the isolation cylinder, and the bottom end of the isolation cylinder is only in contact with the filter barrel without a complicated connection structure. Even if it is immersed in the sugar material and the two are adhered, it is easy to disassemble; finally, the introduction cylinder is also detachably connected to the filter barrel and / or the tank body through the top, and its top will also not be immersed in the sugar material and affect its disassembly, making it easy to disassemble.

DETAILED DESCRIPTION

[0025] The following are specific implementations of the present invention, and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0026] A detachable sugar material filtering screen, such as Figures 1-3 As shown, it includes a tank body 1 provided with an inlet, and a filter element 2 arranged in the tank body 1.

[0027] The filter element 2 first includes a filter barrel 21 with first filter holes 211 on the side walls and bottom respectively. The top of the filter barrel 21 is detachably connected to the tank body 1. There are gaps between the side walls of the filter barrel 21 and the inner wall of the tank body 1, and between the bottom of the filter barrel 21 and the bottom of the tank body 1. The connection method between the filter barrel 21 and the tank body 1 is not limited. For example, a first lap ring 31 can be set on the top of the filter barrel 21, and the first lap ring 31 can be lapped on the top of the tank body 1. In some embodiments, such as Figure 3 As shown, the first lap ring 31 and the top of the tank body 1 can be horizontal. In other embodiments, as shown in FIG. Figure 1 and Figure 2 , control the inner ring end of the first lap ring 31, which is used to connect with the top of the filter barrel 21, to tilt relative to the outer ring end, toward the bottom of the filter barrel 21, so that the first lap ring 31 forms an inverted frustum-shaped cylinder, and guides the sugar material through its inclined inner wall. Correspondingly, the top of the tank body 1 is also set to an inverted frustum-shaped, for the first lap ring 31 to overlap. When in use, the sugar material is fed into the filter barrel 21 in the tank body 1 through the inlet, and the sugar material filtrate flows out of the filter barrel 21 through the first filter hole 211 and is stored in the gap between the tank body 1 and the filter barrel 21, and the sugar material impurities remain in the filter barrel 21. After taking out the filter barrel 21, the filtrate can be poured out of the tank body 1. In some embodiments, such as Figure 3 As shown, an outlet can also be provided on the tank body 1 so that the filtrate can be discharged directly from the outlet without removing the filter element 2. In some embodiments, to facilitate the removal of the filter barrel 21, the first lap ring 31 is provided with a handle. In this application, since the filter barrel 21 is lapped on the tank body 1 at the top, the connection between the two will not be immersed in the sugar material and affect its removal, thus facilitating disassembly and also facilitating the cleaning of the filter barrel 21 and the tank body 1 after filtration.

[0028] Since the impurities in the sugar material are sticky, after a period of filtration, the impurities gather at the bottom of the filter barrel 21 and block the first filter hole 211 at the bottom of the filter barrel 21, affecting the durability of the filter barrel 21. Figure 2 As shown, first, the bottom structure of the filter barrel 21 is adjusted: the originally horizontal bottom is adjusted to a conical structure with an outer diameter that increases from the top to the bottom of the filter barrel 21. When impurities accumulate at the bottom of the filter barrel 21, the conical surface guides them outward, making the first filter hole 211 at the center of the bottom of the filter barrel 21 less likely to be blocked by impurities, allowing subsequent sugar material to be filtered.

[0029] Secondly, based on the bottom of the conical structure of the filter barrel 21, the filter element 2 also includes a guide member arranged in the filter barrel 21. The function of the guide member is to reduce the speed at which the bottom of the filter barrel 21 is completely blocked.

[0030] The guide member first includes an isolation cylinder 22, which is placed directly in the filter barrel 21, and the bottom end of the isolation cylinder 22 abuts the bottom of the filter barrel 21. The conical bottom of the filter barrel 21 allows the isolation cylinder 22 to be mounted on the conical structure, and the conical bottom is used to fix and support the isolation cylinder 22, preventing unnecessary movement of the isolation cylinder 22. Since the isolation cylinder 22 only abuts the filter barrel 21 without a complex connection structure, even if this connection part is soaked in the sugar material and the two adhere to each other, as long as the top of the isolation cylinder 22 is held and a slight force is applied upward, the isolation cylinder 22 can be easily removed from the filter barrel 21, which is convenient for cleaning after filtration. In addition, the height of the isolation cylinder 22 is less than the height of the filter barrel 21, so that a second transfer port 242 is formed between the top of the isolation cylinder 22 and the filter barrel 21.

[0031] The separator 22 divides the bottom of the filter barrel 21 into two sections, designated as the central filter section 21a and the outer filter section 21b. Due to the barrier effect of the separator 22, during use, the sugar material is first fed into the separator 22 and contacts the central filter section 21a at the bottom of the filter barrel 21. The filtrate is then filtered directly through the first filter holes 211 of the central filter section 21a. Impurities accumulate on the central filter section 21a and, due to the diversion effect of the conical bottom, flow toward the separator 22, exposing the first filter holes 211 in the center of the central filter section 21a for further filtration. When the central filter section 21a is completely clogged with impurities, the continuously flowing sugar material cannot be filtered and reduced, resulting in continuous accumulation. When the sugar material in the separator 22 accumulates to a certain height, it can flow through the second transfer port 242 between the filter barrel 21 and the separator 22, where it can be filtered again through the first filter holes 211 of the outer filter section 21b, which were previously unused, as well as the first filter holes 211 in the sidewall of the filter barrel 21.

[0032] In some embodiments, as Figure 3 As shown, the isolation cylinder 22 is provided with a second filter hole 221. During the stacking process, the sugar material can be initially filtered through the second filter hole 221, then flow into the space between the filter barrel 21 and the isolation cylinder 22, and then finely filtered through the first filter hole 211. The second filter hole 221 mainly serves to guide the flow and provide preliminary filtration. Its pore size does not need to be too small, and it can be no smaller than the pore size of the first filter hole 211.

[0033] In some embodiments, a plurality of isolation cylinders 22 with successively decreasing inner diameters may be provided from the outside to the inside to further slow down the speed at which the bottom of the filter barrel 21 is completely blocked, thereby improving the durability of the device.

[0034] The flow guide also includes an inlet tube 23 to ensure that all the sugar content is directed into the isolation tube 22. The inlet tube 23 is positioned within the isolation tube 22. A top opening is provided at the top of the inlet tube 23, connected to the inlet. A first transfer port 241 is formed between the bottom of the inlet tube 23 and the isolation tube 22. During use, the sugar content enters the inlet of the inlet tube 23, flows through the inlet tube 23 toward the central filter 21a, and then flows through the first transfer port 241 and the second transfer port 242 toward the outer ring filter 21b.

[0035] The top of the introduction cylinder 23 is detachably connected to the filter barrel 21 or / and the tank body 1. The detachable connection method is not limited. In some embodiments, Figure 2 As shown, similar to the filter barrel 21, a second lap ring 32 is provided on the top of the introduction cylinder 23, and the second lap ring 32 is overlapped on the first lap ring 31. In other embodiments, such as Figure 3 As shown, in order to improve the stability effect, the first lap ring 31 and the second lap ring 32 are both set to a planar structure. At this time, in order to facilitate the introduction of the sugar material, the second lap ring 32 is connected to the introduction cylinder 23 through the guide cylinder 33, and the inner diameter of the guide cylinder 33 decreases from the top to the bottom of the filter barrel 21. Correspondingly, in order to support the introduction cylinder 23, the first lap ring 31 is connected to the filter barrel 21 through the receiving cylinder 34, and the outer wall of the guide cylinder 33 abuts against the inner wall of the receiving cylinder 34. A reinforcing rib 35 is provided between the outer wall of the receiving cylinder 34 and the inner wall of the tank body 1. In some embodiments, in order to further improve the fixing effect of the tank body 1 and the filter element 2, such as Figure 3 As shown, the can body 1 comprises a can body and a can lid, which is positioned at the inlet. A first lap ring 31 and a second lap ring 32 abut against each other between the can body and the can lid. A positioning groove is provided at the top of the can body, and each of the first and second lap rings 31, 32 has a through hole. The can lid is equipped with an insertion strip that can be inserted through the through hole into the positioning groove. Similarly, because this connection is located at the top, it is not immersed in the sugar mixture and would affect its removal, facilitating removal and cleaning of the inlet tube 23.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
