Abstract
Description
Technical Field
[0001] This utility model relates to the field of food and medicine homology technology, specifically a filtration device for extracts of food and medicine homology. Background Technology
[0002] The role of traditional Chinese medicine (TCM) in health holds an unparalleled place in the hearts of the Chinese people! The Chinese have a long-standing tradition of "medicine and food sharing the same origin," and my country, with its vast territory and abundant resources, boasts a rich collection of medicinal herbs. Furthermore, TCM has a history of using herbal medicines to prevent and treat diseases for thousands of years, accumulating rich experience. TCM's unique advantages include addressing both the symptoms and root causes, minimal side effects, and significant efficacy. It has long been a key focus of research in the medical field and a hot topic in the food industry.
[0003] The existing Chinese patent publication number CN219186128U, entitled "A Filtration Device for Extracts from Food and Medicine Homologous," clearly states in its background technology that "the use of a funnel for suction filtration during the filtration process results in a small filtration area, and the filtration area cannot be adjusted according to the amount of extract, leading to low filtration efficiency." The patent addresses this issue by providing a solution. However, this technology cannot adjust the diameter of the funnel plate according to different extracts from food and medicine homologous, making it difficult for the same device to complete filtration for different extracts.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0023] Please refer to Figure 1-4 This utility model discloses a filtration device for a medicinal and edible extract, comprising a bottom box 1, which serves as the bottom structure of the device, supporting the overall structure and receiving the liquid after filtration of the medicinal and edible extract. An mounting plate 2 is installed on top of the bottom box 1, serving as the mounting structure. A connecting block 12 is located on the inner side of the top of the bottom box 1, and a connecting groove 21 is located on the outer side of the mounting plate 2. The connecting groove 21 is slidably connected to the connecting block 12, allowing the mounting plate 2 to be easily installed and removed from the bottom box 1 for convenient cleaning of the interior of the bottom box 1. A discharge pipe 13 is located on the lower side of one side of the bottom box 1, and a valve 14 is installed on the discharge pipe 13. The liquid inside the bottom box 1 can be discharged through the discharge pipe 13, and the valve 14 is used to open and close the discharge pipe 13.
[0024] A filter box 3 is installed on the upper inner side of the mounting plate 2. The medicinal and edible extract is placed in the filter box 3. A filter port 22 is provided on the inner side of the mounting plate 2, and a mounting frame 23 is provided on the outer side of the filter port 22. A limiting groove 24 is provided on the outer side of the mounting frame 23. A limiting block 32 is provided on the outer bottom of the filter box 3. The limiting block 32 is slidably connected to the limiting groove 24. The bottom of the filter box 3 is mounted on the mounting frame 23 and then on the limiting groove 24 via the limiting block 32, thus limiting the position of the filter box 3 and fixing its position. Conversely, it facilitates disassembly. The filtered medicinal and edible extract is then removed, with the filter port 22 located at the bottom of the filter box 3. A rectangular groove 44 is provided on one side of the filter box 3, and a filter frame 4 is provided inside the rectangular groove 44. A detachable filter screen 41 is provided on the filter frame 4. The filter screen 41 is installed inside the filter box 3 by sliding the filter frame 4 inside the rectangular groove 44. The filter screen 41 can be removed, so different sizes of filter screens 41 can be replaced, which is convenient for filtering different medicinal and edible extracts. The filtered liquid falls into the bottom box 1 through the filter port 22.
[0025] The filter box 3 has sliding grooves 34 on both sides inside, and the filter frame 4 has sliding strips 43 on both sides. The sliding strips 43 slide on the sliding grooves 34, keeping the filter frame 4 stable during sliding. The filter frame 4 has fixing plates 5 on both sides outside. The filter frame 4 has a rotating opening 42 on the outside. The fixing plate 5 has a rotating bolt 51 on one side, which connects to the rotating opening 42 and moves on the rotating opening 42. The fixing plate 5 has a locking slot 52 on the other side, and the filter box 3 has locking bolts 53 on both sides. The locking slot 52 is located at the locking bolt 53. The filter frame 4 is fixed by rotating the rotating bolt 51 on the rotating port 42 when the filter screen 41 is installed inside the filter box 3. The other side of the buckle 52 is connected to the buckle 53 by rotating the bolt 51. The top of the filter box 3 is provided with a top cover 33, and the top of the top cover 33 is provided with a vent 31. The bottom box 1 is provided with a suction pipe 11 on one side. That is, when filtering, air is drawn out through the suction pipe 11 and vented through the vent 31, so that a negative pressure is formed in the liquid storage tank, thereby filtering the extract in the filter box 3.
[0026] The working principle of this utility model is as follows: When the device is in use, the filter frame 4 slides inside the rectangular groove 44, thereby installing the filter screen 41 inside the filter box 3. The rotating bolt 51 rotates on the rotating opening 42, causing the locking slot 52 on the other side to connect with the locking bolt 53, thus fixing the filter frame 4. The sliding strip 43 slides on the sliding groove 34, keeping the filter frame 4 stable during sliding. The bottom of the filter box 3 is mounted on the mounting frame 23 and is mounted on the limiting groove 24 by the limiting block 32, thereby limiting the position of the filter box 3 and fixing its position. The medicinal and edible extract is placed in the filter box 3. During filtration, air is drawn in through the suction pipe 11 and vented through the vent 31 to create a negative pressure in the storage tank, thereby filtration of the extract in the filter box 3. After filtration, the filtered medicinal and edible extract is removed by disassembling the filter box 3. The filtered liquid falls into the bottom box 1 through the filter port 22. The liquid inside the bottom box 1 can be discharged through the discharge pipe 13. The connecting block 12 is connected through the connecting groove 21, so that the mounting plate 2 can be disassembled and installed on the bottom box 1 for easy cleaning of the inside of the bottom box 1.
[0027] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
