Description

Technical Field

[0001] The utility model relates to the technical field of decocting appliances, and in particular to a feeding structure for an isolation cylinder. Background Art

[0002] An existing isolation cover is directly pressed on the upper part of the medicinal materials such as flowers, leaves, and stems in the tank body, and the weight of the isolation cover itself is used to press the materials to limit the medicinal materials below the water surface; however, the existing decocting method still requires putting the later-added medicinal materials into the tube body during the decocting of the earlier-added medicinal materials. Therefore, we designed a structure of an isolation cylinder added below the isolation cover. However, in this way, the newly added medicinal materials often have no space limit in the isolation cylinder, and the medicinal materials will be higher than the liquid level in the tank body as the water absorption increases or the water in the tank body decreases during the decocting process, which is not conducive to the effective utilization of the medicinal materials.

[0003] Therefore, it is urgently necessary to propose a feeding structure for an isolation cylinder to solve the problems raised. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a feeding structure for an isolation cylinder to limit the height of the medicinal materials placed in the isolation cylinder and avoid the medicinal materials in the isolation cylinder being higher than the liquid level of the medicinal soup during the decocting process.

[0027] Please refer to Figures 1 to 8 , an isolation cylinder feeding structure of the present utility model is applied in a decocting utensil such as a tank body 100. The function of this isolation cylinder feeding structure is to artificially form a relatively isolated space inside the traditional Chinese medicine materials placed in the tank body 100 first, and this space is used for placing the later materials.

[0028] The feeding structure of an isolation cylinder of the present utility model includes a cylinder body 200, and the cylinder body 200 is used to be placed at the bottom end of the tank body 100 for later putting in medicinal materials; a plurality of small holes 201 are spaced apart and provided at the bottom end of the cylinder body 200, and the liquid medicine in the tank body 100 can freely flow inside and outside the cylinder body 200 through the small holes 201, and in addition, it can prevent the Chinese medicinal materials previously put into the tank body 100 from entering the cylinder body 200; specifically, one end of the cylinder body 200 is provided with a bottom wall, and the small holes 201 are spaced apart and provided on the bottom wall and the side wall of the cylinder body 200 close to the bottom wall; in this embodiment, the small holes 201 on the side wall are distributed within a height range of 1 cm from the bottom wall.

[0029] A limiting cover 300 is placed inside the cylinder body 200, and the limiting cover 300 presses on the upper part of the medicinal materials inside the cylinder body 200. The limiting cover 300 includes an inner ring 310, an outer ring 320 and a connecting member 330. The inner ring 310 and the outer ring 320 are fixed together through the connecting member 330. The connecting members 330 are arranged at intervals in a radial pattern within the annular space between the inner ring 310 and the outer ring 320, so as to limit the height of the medicinal materials placed inside the cylinder body 200 and avoid the medicinal materials inside the cylinder body 200 being higher than the liquid level of the medicinal soup during the decocting process.

[0030] In this embodiment, the connecting member 330 is an elastic support structure. The outer ring 320 includes an annular rubber tube 321 and several arc segments 322 wrapped therein. The several arc segments 322 are arranged at intervals within the annular rubber tube 321, and the annular rubber tube 321 is made of silica gel material. During manufacturing, take a complete annular rubber tube 321, the diameter of the annular rubber tube 321 is larger than the maximum diameter of the inner ring 310, and use a tool to cut open the inner side of the annular rubber tube 321 for standby. The arc segments 322 are actually arc-shaped thick stainless steel wires, and the number thereof is determined according to actual situations. For example, in this embodiment, 24 arc segments 322 are provided in total. Each arc segment 322 is squeezed into the tube from the inner side of the annular rubber tube 321, and finally the distance between segments is adjusted to make them evenly arranged within the annular rubber tube 321. After the outer ring 320 is manufactured, it is concentrically arranged outside the inner ring 310, and then the inner ring 310 and the outer ring 320 are connected through the connecting member 330.

[0031] Specifically, the connecting member 330 is arranged to match the arc segments 322, and the number of the connecting members 330 is also set to 24. In this embodiment, the connecting member 330 adopts a compression spring structure. During manufacturing, one end of the compression spring is fixedly welded to the inner ring 310, and the other end of the compression spring is welded to the middle of an arc segment 322; repeat this step, and then connect the 24 arc segments 322 to the inner ring 310 one by one. The 24 compression springs are arranged in a radial pattern as a whole. After manufacturing, the inner ring 310, the outer ring 320 and the connecting member 330 are located in a plane.

[0032] In this way, a simple outer ring 320 is manufactured. The arc segments 322 are arranged at intervals in the annular rubber tube 321, so that the outer ring 320 has a soft and hard main structure, so that the outer ring 320 can be deformed under the action of external force. With the compression spring connected between the inner ring 310 and the outer ring 320, the outer diameter of the entire limit cover 300 can be elastically changed within a certain range, that is, the outer ring 320 is converted between a contracted state and an expanded state with the help of the connecting piece 330. This structural setting, on the one hand, facilitates the smooth placement of the entire limit cover 300 into the barrel body 200; on the other hand, after the limit cover 300 is placed in place, the outer ring 320 is stretched open under the elastic force of the compression spring, so that the outer ring 320 maintains elastic contact with the inner wall of the barrel body 200, thereby preventing the limit cover 300 from easily shifting.

[0033] Specifically, during the decoction process of putting the medicinal materials into the tank body 100 first, the medicinal materials need to be put into the barrel body 200 in the tank body 100 later, and the limiting cover 300 is placed in the barrel body 200 after the medicinal materials are put into the barrel body 200; at this time, the liquid level in the barrel body 200 needs to exceed the height of the medicinal materials put in later, for example, 1-2 cm, and the specific value can be flexibly set according to the expansion characteristics of the Chinese medicinal materials and the decoction time; and the position of the limiting cover 300 is below the liquid level in the barrel body 200 and above the medicinal materials put in the barrel body 200. During the heating process, the medicinal materials absorb water as a whole and expand. When they contact the limiting cover 300 in the barrel body 200, they will push the limiting cover 300, making it have a tendency to move upward. Since the limiting cover 300 elastically contacts the barrel body 200, it can avoid a large displacement of the limiting cover 300, thereby achieving the purpose of limiting the expansion of the Chinese medicinal materials.

[0034] It should be noted that the overall structure formed by the inner ring 310, the outer ring 320 and the connecting piece 330 includes some hollow parts, but the expanded Chinese medicinal materials are entangled together rather than a loose structure, so the limiting cover 300 as a whole can still play the role of blocking the Chinese medicinal materials.

[0035] In one embodiment, the limiting cover 300 further includes a first gauze (not shown), which is wrapped around the inner ring 310 and the outer ring 320. The inner ring 310, the outer ring 320 and the connecting member 330 together support the first gauze. The first gauze can further prevent the Chinese medicinal materials from escaping from the limiting cover 300, ensuring that no Chinese medicinal materials will pass through the limiting cover 300 and run to the top. Specifically, the first gauze can be made of a soft net made of food-grade materials such as stainless steel wire, gauze or silicone.

[0036] In one embodiment, the inner ring 310 includes three annular rings 311 which are concentrically arranged and welded together by several stainless steel rods. In this embodiment, the number of stainless steel rods is eight, which are welded in a cross shape on one side of the three annular rings 311 to connect the three annular rings 311 into one body. After welding, the three annular rings 311 are located in the same plane. In this embodiment, the annular rings 311 are all made of stainless steel, and the innermost annular ring 311 can be designed as a solid structure.

[0037] In one embodiment, the cylinder body 200 includes an outer cylinder 210 and an inner cylinder 220. The two ends of the inner cylinder 220 are penetrated, and the inner cylinder 220 is placed inside the outer cylinder 210 in a reciprocating telescopic and positioning manner. The small hole 201 is opened on the outer cylinder 210.

[0038] Further, at least one silicone ring 230 is arranged at intervals on the outer side wall of the inner cylinder 220. The silicone ring 230 is placed between the inner cylinder 220 and the outer cylinder 210 and is used to provide resistance for the inner cylinder 220 to perform telescopic movement, so that the inner cylinder 220 can be telescopically and positioned inside the outer cylinder 210. This structure can keep the relative positions of the inner cylinder 220 and the outer cylinder 210 unchanged without external force and will not easily generate slippage. This telescopic structure enables the utility model to adapt to the tank body 100 structures of different depths.

[0039] In one embodiment, a cylinder cap 221 protrudes outward from the circumferential side of the opening at the upper end of the inner cylinder 220. The inner cylinder 220 realizes the limitation of the relative displacement between the inner cylinder 220 and the outer cylinder 210 through the structure of the cylinder cap 221, avoiding the inner cylinder 220 being overly placed inside the outer cylinder 210 and affecting the telescopic positioning effect of the inner cylinder 220 inside the outer cylinder 210; in addition, through the displacement limitation of the inner cylinder 220 inside the outer cylinder 210 by the cylinder cap 221, it is avoided that the inner cylinder 220 overly enters the inside of the outer cylinder 210 and blocks the small hole 201 opened at the bottom end of the outer cylinder 210, thus affecting the liquid medicine circulation effect between the inside and outside of the outer cylinder 210.

[0040] In one embodiment, an isolation cylinder depth adjustment structure of the utility model further includes a decocting cover 400. The circumferential side of the decocting cover 400 is closely arranged close to the inner side of the tank body 100. A through hole 401 is opened in the middle of the decocting cover 400, and the cylinder body 200 passes through the through hole 401; specifically, the inner cylinder 220 passes through the through hole 401 and is placed inside the outer cylinder 210. The decocting cover 400 surrounds the outer side of the inner cylinder 220 and is placed below the cylinder cap 221. Thus, during use, the cross-sectional structure formed by the combination of the decocting cover 400 and the cylinder body 200 is a T-shaped structure, so that the cylinder body 200 can be stably placed in the tank body 100 to improve the convenience of putting in medicinal materials.

[0041] Further, the decocting cover 400 includes a small ring 410, a large ring 420 and an elastic support assembly 430. The small ring 410 includes three circular rings 411, which are concentrically arranged and welded together by several stainless steel rods. In this embodiment, the number of stainless steel rods is eight, which are welded in a cross shape on one side of the three circular rings 411, so that the three circular rings 411 are integrated. After welding, the three circular rings 411 are in the same plane. The through hole 401 is provided on the small ring 410, and this through hole 401 is actually the center of the smallest circular ring 411. In this embodiment, the circular rings 411 are all made of stainless steel rings.

[0042] The large ring 420 includes a silica gel ring tube 421 and several arc segments 422 covered therein, and the several arc segments 422 are arranged at intervals in the tube. During production, take a complete silica gel ring tube 421 with a diameter larger than the maximum diameter of the small ring 410, and use a tool to cut open the inner side of the silica gel ring tube 421 for standby. The arc segments 422 are actually arc-shaped thick stainless steel wires, and the number thereof is determined according to actual conditions. For example, in this embodiment, there are 24 arc segments 422 in total. Each arc segment 422 is inserted into the tube from the inner side of the silica gel ring tube 421, and finally the distance between segments is adjusted to make them evenly arranged in the tube. After the large ring 420 is made, it is concentrically arranged outside the small ring 410, and then the small ring 410 and the large ring 420 are connected by the elastic support assembly 430.

[0043] Specifically, the elastic support assembly 430 includes several elastic members 431. Matched with the arc segments 422, the number of elastic members 431 is also set to 24. In this embodiment, the elastic members 431 are compression springs. During production, one end of the compression spring is fixedly welded on the small ring 410, and the other end of the compression spring is welded in the middle of an arc segment 422; repeat this step, and then connect the 24 arc segments 422 to the small ring 410 one by one. The 24 compression springs are arranged in a radial pattern as a whole. After being made, the small ring 410, the large ring 420 and the elastic support assembly 430 are in the same plane.

[0044] In this way, a simple large ring 420 is made. The arc segments 422 are arranged at intervals in the silicone ring tube 421, so that the large ring 420 has a soft and hard main structure, so that the large ring 420 can be deformed under the action of external force. With the compression spring connected between the small ring 410 and the large ring 420, the outer diameter of the entire frying cover 400 can be elastically changed within a certain range, that is, the large ring 420 is converted between a contracted state and an expanded state with the help of the elastic support component 430. This structural setting, on the one hand, facilitates the smooth placement of the entire frying cover 400 into the tank body 100; on the other hand, after the frying cover 400 is placed in place, the large ring 420 is stretched open under the elastic force of the compression spring, so that the large ring 420 maintains elastic contact with the inner wall of the tank body 100, thereby preventing the frying cover 400 from easily moving.

[0045] Specifically, when in use, the decoction cover 400 is loaded into the tank body 100 after the medicinal materials and water. Generally, the liquid level of the water exceeds the highest point where the Chinese medicinal materials are piled and spread, for example, by 1-2 cm. The specific value can be flexibly set according to the expansion characteristics of the Chinese medicinal materials and the decoction time; and the position of the decoction cover 400 is below the liquid level and above the Chinese medicinal materials. For example, the decoction cover 400 is positioned at a height of 1 cm from the highest point of the Chinese medicinal materials and immersed in water. During the heating process, the Chinese medicinal materials expand as a whole. When they contact the decoction cover 400, they will push the decoction cover 400, making it have a tendency to move upward. Since the large ring 420 elastically contacts the inner wall of the tank, friction can be generated, thereby preventing the decoction cover 400 from having a large displacement, thereby achieving the purpose of limiting the expansion of the Chinese medicinal materials. By designing the initial water addition amount and the position of the decoction cover 400, it can be ensured that the Chinese medicinal materials will not exceed the liquid level during the entire decoction process, thereby ensuring the extraction and reaction of the effective ingredients in the medicinal materials and ensuring the efficacy.

[0046] It should be noted that the overall structure formed by the small ring 410, the large ring 420 and the elastic support component 430 includes some hollow parts, but the expanded Chinese medicinal materials are entangled together rather than a loose structure, so the decoction cover 400 as a whole can still play the role of blocking the Chinese medicinal materials.

[0047] As a further improvement, the decoction cover 400 of this embodiment further includes a second gauze 440, which is closely attached to the outer sides of the small ring 410, the large ring 420 and the elastic support assembly 430. The second gauze 440 can further prevent the Chinese medicinal materials from escaping from the decoction cover 400, ensuring that no Chinese medicinal materials will pass through the decoction cover 400 and run to the top. Specifically, the second gauze 440 can be made of a stainless steel wire mesh, a gauze mesh or a mesh made of edible materials such as silica gel.

[0048] In summary, in a feeding structure of an isolation cylinder according to the present utility model, a limiting cover 300 is placed in a cylinder body 200, and the limiting cover 300 presses on the medicinal materials in the cylinder body 200. The limiting cover 300 includes an inner ring 310, an outer ring 320 and a connecting member 330. The inner ring 310 and the outer ring 320 are fixed together by the connecting member 330. The connecting members 330 are arranged at intervals in a radial pattern in the annular space between the inner ring 310 and the outer ring 320, so as to limit the height of the medicinal materials placed in the cylinder body 200 and prevent the medicinal materials in the cylinder body 200 from being higher than the liquid level of the medicinal soup during the decocting process.

[0049] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
