For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] See also Figures 1 to 6 The utility model discloses an isolation cover height limiting structure which is applied to a frying vessel such as a tank body. The isolation cover height limiting structure comprises a tank body 100 and an isolation cover 200.

[0026] In this embodiment, the decoction vessel is a common tank body 100 structure with a constricted mouth structure, which has a tank mouth, an inner belly and a flat bottom. The tank mouth is funnel-shaped from top to bottom, and the tank mouth is connected to the inner belly, which is approximately ellipsoidal, wherein the minimum horizontal cross-section of the tank mouth is smaller than the maximum horizontal cross-section of the inner belly. The tank body 100 structure with such a constricted mouth structure is a relatively common decoction device, but the utility model is not limited thereto. In some other embodiments, a straight cylindrical tank body with equal upper and lower sizes can also be used. Since the tank body 100 is used to decoct food and medicinal materials, the depth of the tank body 100 is generally large.

[0027] The steps of decocting Chinese medicinal materials are generally as follows: put the Chinese medicinal materials into the tank 100, then pour in an appropriate amount of water to cover the Chinese medicinal materials, and then start heating and decocting. Chinese medicinal materials are dried plant roots, stems, leaves, etc., which will absorb water and swell after soaking, especially after heating. The swollen Chinese medicinal materials are higher than the liquid surface. Since this part of the Chinese medicinal materials is not in an ideal water solvent condition, its effective ingredients are difficult to extract, which will greatly affect the extraction of medicinal materials and cause waste.

[0028] However, simply adding an isolation cover 200 in the tank body 100 to cover the medicinal materials, and using the weight of the isolation cover 200 itself to apply force to the medicinal materials to limit the water absorption height of the medicinal materials, the isolation cover 200 will often move upward along with the medicinal materials after they absorb water and expand. There is still a situation in which some medicinal materials are higher than the liquid level during the decoction process, which is not conducive to the effective use of the medicinal materials.

[0029] The isolation cover height limiting structure of the present embodiment can effectively solve the above-mentioned problem by improving the structure of the tank body 100 and cooperating with the isolation cover 200.

[0030] See also Figures 1 to 6 The utility model discloses an isolation cover height limiting structure, which includes a tank body 100 and an isolation cover 200. A plurality of limiting protrusions 110 at different height layers are sequentially arranged in the tank body 100 from bottom to top, wherein the limiting protrusions 110 at the same height layer are arranged in a ring shape on the inner wall of the tank body 100, and the surrounding side of the isolation cover 200 is arranged close to the inner wall of the tank body 100 and is located under the limiting protrusions 110 corresponding to one of the height layers; when in use, the isolation cover 200 is placed under the limiting protrusions 110 set at one of the height layers as required. After the medicinal materials in the tank body 100 are boiled and expanded, the isolation cover 200 will be driven to move upward together with it. After the isolation cover 200 moves upward for a certain displacement, the surrounding side of the isolation cover 200 will It is tightly pressed against the limiting protrusion 110 set at this height layer, and the limiting protrusion 110 set at this height layer limits the isolation cover 200 from continuing to move upward, so as to prevent the medicinal materials from absorbing water and expanding during the decoction process, resulting in excessive displacement of the isolation cover 200, so that the medicinal materials below the isolation cover 200 slowly absorb water and expand during the decoction process until the medicinal materials are effectively extracted, thereby effectively improving the utilization rate of the medicinal materials; in this embodiment, the limiting protrusions 110 at different height layers can be on a vertical line, or can be staggered as needed, which is not necessary to elaborate here; wherein, the limiting protrusion 110 at the lowest height layer is a preset distance from the bottom end of the tank body 100, and the preset distance can meet the most basic medicinal material amount in the middle and late stages of decoction. The liquid level height of the decoction.

[0031] In one embodiment, the limiting protrusion 110 is hemispherical in structure to facilitate the limiting of the isolation cover 200; in addition, it is also convenient for the isolation cover 200 to slide along the surface of the limiting protrusion 110 at a lower height layer to below the limiting protrusion 110 at a higher height layer, or slide along the surface of the limiting protrusion 110 at a higher height layer to above the limiting protrusion 110 at a lower height layer, thereby completing the adjustment of the placement requirements of the isolation cover 200 at different heights.

[0032] In one embodiment, the isolation cover 200 includes an inner ring 210, an outer ring 220 and a gauze 230, the inner ring 210 and the outer ring 220 are fixed together by a connector 240, the connector 240 is radially arranged in an annular space between the inner ring 210 and the outer ring 220, the gauze 230 is wrapped around the inner ring 210 and the outer ring 220, the inner ring 210, the outer ring 220 and the connector 240 jointly complete the support effect of the gauze 230, and the setting of the gauze 230 can further prevent the Chinese medicinal materials from escaping from the isolation cover 200, ensuring that no Chinese medicinal materials will pass through the isolation cover 200 and run to the top. Specifically, during production, the gauze 230 can be made of a soft net made of food-grade materials such as stainless steel wire, gauze or silicone.

[0033] In this embodiment, the connecting piece 240 is an elastic support structure, and the outer ring 220 includes a silicone ring tube 221 and a plurality of arc segments 222 wrapped therein, and the plurality of arc segments 222 are arranged at intervals in the silicone ring tube 221. When making, take a complete silicone ring tube 221, the diameter of which is larger than the maximum diameter of the inner ring 210, and use a cutter to cut the inner side of the silicone ring tube 221 for standby use. The arc segment 222 is actually an arc-shaped thick stainless steel wire, and its number is determined according to actual conditions. For example, in this embodiment, the arc segment 222 is provided with 24 segments, and each arc segment 222 is squeezed into the tube from the inner side of the silicone ring tube 221, and finally the distance between the segments is adjusted so that it is evenly arranged in the silicone ring tube 221. After the outer ring 220 is made, it is concentrically arranged outside the inner ring 210, and then the inner ring 210 is connected to the outer ring 220 through the connecting piece 240.

[0034] Specifically, the connector 240 is matched with the arc segment 222, and the number of the connectors 240 is also set to 24. In this embodiment, the connector 240 adopts a compression spring structure. During production, one end of the compression spring is fixedly welded to the inner ring 210, and the other end of the compression spring is welded to the middle of an arc segment 222; repeat this step, and then connect the 24 arc segments 222 to the inner ring 210 one by one, and the 24 compression springs are arranged radially as a whole. After production, the inner ring 210, the outer ring 220 and the connector 240 are located in a plane.

[0035] In this way, a simple outer ring 220 is manufactured. The arc segments 222 are arranged at intervals in the silicone ring tube 221, so that the outer ring 220 has a soft and hard main structure, so that the outer ring 220 can be deformed under the action of external force. With the compression spring connected between the inner ring 210 and the outer ring 220, the outer diameter of the entire isolation cover 200 can be elastically changed within a certain range, that is, the outer ring 220 is converted between a contracted state and an expanded state by means of the connecting piece 240. This structural setting, on the one hand, facilitates the smooth placement of the entire isolation cover 200 into the frying vessel, especially the tank body 100 structure with a shrinking structure; on the other hand, after the isolation cover 200 is placed in place, the outer ring 220 is stretched open under the elastic force of the compression spring, so that the outer ring 220 maintains elastic contact with the inner wall of the frying vessel, thereby preventing the isolation cover 200 from easily moving.

[0036] Furthermore, a through hole 201 is provided in the middle of the isolation cover 200. Specifically, the through hole 201 is arranged in the middle of the inner ring 210. An isolation cylinder 300 is placed at the through hole 201 of the isolation cover 200. The function of the isolation cylinder 300 is to artificially form a relatively isolated space inside the Chinese medicinal materials first placed in the tank body 100, and the space is used to place the medicinal materials later; the isolation cylinder 300 includes an outer cylinder 310 and an inner cylinder 320. The outer cylinder 310 is placed below the isolation cover 200, and the inner cylinder 320 is arranged through the through hole 201. The inner cylinder 320 can be telescopically positioned back and forth and placed on the inner side of the outer cylinder 310. The two ends of the inner cylinder 320 are through-set, so as to facilitate the user to pass through. The medicinal materials are placed into the outer cylinder 310 through the opening at the upper end of the inner cylinder 320; a plurality of small holes 311 are spaced apart at the bottom end of the outer cylinder 310, and the medicinal liquid in the decoction vessel can be freely circulated inside and outside the outer cylinder 310 through the small holes 311, and can also prevent the Chinese medicinal materials placed in the decoction vessel from entering the outer cylinder 310; in this embodiment, a silicone ring 330 is provided between the inner cylinder 320 and the outer cylinder 310 to provide resistance during telescopic movement, so that the inner cylinder 320 can be telescopically positioned and placed in the outer cylinder 310, and this structure can keep the relative position of the inner cylinder 320 and the outer cylinder 310 unchanged in the absence of external force, and will not easily slip.

[0037] In this embodiment, the design height of the limiting protrusion 110 is matched with the extension height of the isolation tube 300, and the height of the height layer where the limiting protrusion 110 is located in the tank body 100 is designed to be three height values, which respectively correspond to the telescopic positioning degree of the inner tube 320 in the outer tube 310; while ensuring that the initial position of the isolation tube 300 is at the bottom end of the tank body 100, as the inner tube 320 is extended and positioned in the outer tube 310, the height of the isolation tube 300 will increase, and as the height of the isolation tube 300 increases, the isolation cover 200 connected to the isolation tube 300 will be between the limiting protrusions 110 corresponding to the two height layers or below the limiting protrusion 110 corresponding to the lowest height layer.

[0038] Furthermore, the inner cylinder 320 is provided with a cylinder cap 321 protruding outwardly around the opening of the upper end, and the cylinder cap 321 is attached to the top of the isolation cover 200. The inner cylinder 320 can be stably suspended on the isolation cover 200 through the cylinder cap 321 structure.

[0039] In one embodiment, the isolation cylinder 300 further includes a cylinder cover 340, which is used to cover the opening of the upper end of the inner cylinder 320 to prevent the medicinal materials placed in the outer cylinder 310 from overflowing through the opening of the upper end of the inner cylinder 320 after the decoction in the tank body 100 exceeds the height of the upper end of the inner cylinder 320, thereby affecting the release of effective ingredients of the medicinal materials.

[0040] When the utility model is used, the isolation cover 200 is placed in the tank body 100 after the medicinal materials and water are added. Generally, the liquid level of the water exceeds the highest point of the piled and spread Chinese medicinal materials, for example, by 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 isolation cover 200 is located below the liquid level and above the Chinese medicinal materials, for example, the isolation cover 200 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 the medicinal materials contact the isolation cover 200, they will push the isolation cover 200, causing it to tend to move upward. Since the surrounding side of the isolation cover 200 is below the limiting protrusion 110 corresponding to one of the height layers of the tank body 100, as the isolation cover 200 rises below the limiting protrusion 110, the limiting protrusion 110 set at the height layer restricts the isolation cover 200 from continuing to move upward, thereby preventing the medicinal materials from absorbing water and expanding during the decoction process, causing excessive displacement of the isolation cover 200. As a result, the medicinal materials below the isolation cover 200 slowly absorb water and expand during the decoction process until the medicinal materials are effectively extracted, thereby effectively improving the utilization rate of the medicinal materials.

[0041] In summary, the utility model provides an isolation cover height limiting structure by setting a plurality of limiting protrusions 110 at different height layers in the tank body 100, and coordinating the limiting protrusions 110 at the same height layer to be arranged in a ring shape on the inner wall of the tank body 100. During the heating process, the medicinal materials expand as a whole. When the medicinal materials contact the isolation cover 200, they will push the isolation cover 200, causing it to have a tendency to move upward. Since the peripheral side of the isolation cover 200 is located below the limiting protrusions 110 corresponding to one of the height layers of the tank body 100, as the isolation cover 200 rises to below the limiting protrusions 110, the limiting protrusions 110 set at the height layer restrict the isolation cover 200 from continuing to move upward, thereby preventing the medicinal materials from absorbing water and expanding during the decoction process, causing the isolation cover 200 to be excessively displaced, so that the medicinal materials below the isolation cover 200 slowly absorb water and expand during the decoction process until the medicinal materials are effectively extracted, thereby effectively improving the utilization rate of the medicinal materials.

[0042] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
