[0022] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0023] like Figure 1-5 A non-powered extraction device comprises an extraction tank 1, a cavity 10 is formed in the extraction tank 1, a filter plate 2 and a pressure plate structure 3 are arranged in the cavity 10, a spring 4 is arranged between the pressure plate structure 3 and the filter plate 2, and an extraction cavity 5 is formed between the pressure plate structure 3 and the filter plate 2, the pressure plate structure 3 comprises a first pressure plate 31 and a second pressure plate 32, the first pressure plate 31 and the second pressure plate 32 are rotatably and movable up and down in the cavity 10, the second pressure plate 32 is at one end close to the filter plate 2, the first pressure plate 31 is at one end away from the filter plate 2, a first material passing hole 311 and a water passing hole 312 are arranged on the first pressure plate 31, and a second material passing hole 321 is arranged on the second pressure plate 32.

[0024] The utility model proposes a non-powered extraction device, which rotates a first pressing plate 31 and a second pressing plate 32 so that a first feeding hole 311 on the first pressing plate 31 is connected with a second feeding hole 321 on the second pressing plate 32. When the material enters the cavity 10, it enters the extraction cavity 5 through the first feeding hole 311 of the first pressing plate 31 and the feeding hole on the second pressing plate 32. At this time, the first pressing plate 31 is rotated so that the water feeding hole 312 on the first pressing plate 31 is connected with the second feeding hole 321. At this time, water is added to immerse the material in the extraction cavity 5, and then steam is introduced for extraction. After the extraction is completed, the extract flows out by rotating the first pressing plate 31, and the first feeding hole 311 and the water hole 312 on the first pressing plate 31 are not connected with the second feeding hole 321 of the second pressing plate 32. Water gathers in the cavity 10 and above the first pressing plate 31. At this time, under the action of gravity, the first pressing plate 31 and the second pressing plate 32 approach the filter plate 2, squeezing out the extract on the residue in the extraction chamber 5. The material extraction can be completed without installing a power device, which is convenient for extraction.

[0025] The pressure plate structure 3 also includes a scraper plate 33, which is rotatable above the first pressure plate 31, and the scraper plate 33 cooperates with the upper end surface of the first pressure plate 31 to scrape the material at the upper end surface of the first pressure plate 31 into the first feed hole 311. The scraper plate is rotatable above the first pressure plate, and the material scattered above the first pressure plate can be scraped into the first feed hole by rotating the scraper plate.

[0026] In this embodiment, the scraper plate 33 is a strip-shaped plate.

[0027] In some embodiments, the pressing plate structure 3 further includes a side wall, and a holding cavity 322 with an upward opening is enclosed between the second pressing plate 32 and the side wall. The holding cavity 322 is connected to the extraction cavity 5 through a second material passing hole 321 on the second pressing plate 32.

[0028] In some embodiments, the edge of the second pressing plate 32 extends upward to form the side wall.

[0029] In this embodiment, a water inlet 61 is provided on the top of the extraction tank 1 , and the water inlet 61 is communicated with the containing chamber 322 .

[0030] In this embodiment, a feeding port 62 is provided on the top of the extraction tank 1 , and the feeding port 62 is communicated with the containing chamber 322 .

[0031] When materials are added through the feeding port 62 , the materials enter the containing chamber 322 through the feeding port 62 , and then enter the extraction chamber 5 through the first feeding hole 311 on the first pressing plate 31 and the second feeding hole 321 on the second pressing plate 32 .

[0032] When water is added through the water inlet 61 , the water enters the containing chamber 322 through the water inlet 61 , and then enters the extraction chamber 5 through the water passing hole 312 on the first pressing plate 31 and the second material passing hole 321 on the second pressing plate 32 .

[0033] In this embodiment, the size of the first material passing hole 311 is equal to the size of the second material passing hole 321, and the water passing hole 312 is smaller than the first material passing hole 311. When water needs to be added to the extraction chamber 5, the water passing hole 312 of the first pressing plate 31 is rotated to correspond to the second material passing hole 321 on the second pressing plate 32. Since the water passing hole 312 is smaller than the second material passing hole 321, the material can be prevented from flowing out of the water passing hole 312.

[0034] That is, in the present embodiment, the size of the first feed hole 311 and the second feed hole 321 is larger than the size of the material, and the size of the water hole 312 is smaller than the size of the material, so as to ensure that the material can enter the extraction chamber 5 through the first feed hole 311 and the second feed hole 321, while preventing the material from flowing out of the water hole 312 through the second feed hole 321.

[0035] In this embodiment, the first material passing hole 311 is opened on the first pressing plate 31 along the first diameter of the first pressing plate 31; the water passing hole 312 is opened on the first pressing plate 31 along the second diameter of the first pressing plate 31. The angle between the first diameter and the second diameter is 30-60°.

[0036] The second material passing hole 321 is opened on the second pressing plate 32 along the third diameter of the second pressing plate 32 .

[0037] The first pressing plate 31 and the second pressing plate 32 are equal in size.

[0038] A liquid outlet hole 63 is provided at the bottom of the extraction tank 1, and a liquid outlet valve is provided at the liquid outlet hole 63. When water is added into the cavity 10, the water hole 312 on the first pressing plate 31 is connected with the second material hole 321 on the second pressing plate 32, and the liquid outlet hole 63 is closed by the liquid outlet valve. Since the filter plate 2 is provided with the filter hole 21, water can enter the extraction cavity 5 through the water hole 312 on the first pressing plate 31 and the second material hole 321 on the second pressing plate 32, and enter the cavity 10 below the filter plate 2 through the filter hole 21 on the filter plate 2. When the space of the cavity 10 below the filter plate 2 is filled with water, the water will gradually fill the extraction cavity 5 to immerse the extraction cavity 5.

[0039] The filter plate 2 includes a filter plate seat 24 and a filter plate body 25 . The filter plate seat 24 is connected to the inner wall of the cavity 10 . The filter plate body 25 is disposed in the filter plate seat 24 and is rotatably connected to the filter plate seat 24 .

[0040] In this embodiment, one end of the spring 4 is connected to the filter plate seat 24 , and the other end is connected to the second pressing plate 32 .

[0041] In this embodiment, a hook 323 is provided at one end of the second pressing plate 32 facing the filter plate 2 , and a hook hole 22 matching with the hook 323 is provided at one end of the filter plate body 25 facing the second pressing plate 32 .

[0042] When the extraction is completed and the residue in the extraction chamber 5 needs to be cleaned, the second pressing plate 32 can be moved closer to the filter plate 2 and rotated 30° so that the hook 323 on the second pressing plate 32 hooks the hook hole 22 on the filter plate 2. Then, by lifting the second pressing plate 32, the filter plate body 25 can be driven to flip relative to the filter plate seat 24, so that the material in the extraction chamber 5 can enter the cavity 10 below the second pressing plate 32.

[0043] The scraper plate handle 330 is also included, and the scraper plate handle 330 is extended upward from the scraper plate 33 .

[0044] The scraper plate 33 can be rotated by the first pressing plate handle 310. The scraper plate 33 can be rotated by rotating the first pressing plate handle 310, so that the material on the first pressing plate 31 enters the extraction chamber 5 through the first material passing hole 311 and the second material passing hole 321. The scraper plate handle 330 can be rotated to drive the scraper plate 33 to rotate, so that the material on the first pressing plate 31 is scraped into the first material passing hole 311 on the first pressing plate 31.

[0045] The first pressing plate handle 310 is also included. A first cavity is formed in the scraper plate handle 330. The first pressing plate handle 310 is connected to the first pressing plate 31 and extends upward from the first pressing plate 31 through the first cavity. The first pressing plate 31 can be driven to rotate by rotating the first pressing plate handle 310, so that the first pressing plate 31 can be rotated to the point where the first material passing hole 311 on it is connected to the second material passing hole 321 on the second pressing plate 32, or to the point where the water passing hole 312 on it is connected to the second material passing hole 321 on the second pressing plate 32, or to the point where neither the first material passing hole 311 nor the water passing hole 312 on it is connected to the second material passing hole 321 on the second pressing plate 32.

[0046] A second cavity is formed in the first pressing plate handle 310, and the second pressing plate handle 320 is connected to the second pressing plate 32, and the second pressing plate handle 320 is extended upward from the second pressing plate 32 through the second cavity. The second pressing plate handle 320 can be pressed down to drive the second pressing plate 32 to move downward, so that the second pressing plate 32 approaches the filter plate 2 to discharge the extract; or when the second pressing plate 32 approaches the filter plate 2, the second pressing plate 32 can be rotated so that the hook 323 on the second pressing plate 32 hooks the hook hole 22 on the filter plate 2, and then the second pressing plate handle 320 is lifted to drive the second pressing plate 32 to move upward, so as to drive the filter plate body 25 to flip, so that the material residue in the extraction chamber 5 falls.

[0047] It also includes an interlayer 7, which is sleeved on the outside of the extraction tank 1, and steam can pass into the interlayer 7.

[0048] First, the liquid outlet hole 63 is closed by the liquid outlet valve, and the first pressing plate 31 is driven to rotate by the first pressing plate handle 310 until the first feeding hole 311 on the first pressing plate 31 is connected with the second feeding hole 321 on the second pressing plate 32, and the material to be extracted is fed through the feeding port 62, and the material enters the containing chamber 322 through the feeding port 62. A part of the material enters the extraction chamber 5 through the first feeding hole 311 and the second feeding hole 321, and a part of the material remains on the first pressing plate 31. At this time, the scraper plate 33 can be driven to rotate by rotating the scraper plate handle 330 to scrape the material that has not entered the extraction chamber 5 into the extraction chamber 5. Then, the first pressing plate 31 is driven to rotate by the first pressing plate handle 310 until the water hole 312 on the first pressing plate 31 is connected with the second material hole 321 on the second pressing plate 32, and water is passed from the water inlet 61 through the containing cavity 322, the water hole 312, and the second material hole 321 into the extraction cavity 5. Since there are filter holes 21 on the filter plate 2, the water will enter the cavity 10 below the filter plate 2, and then the water gradually immerses the extraction cavity 5. Then, steam is introduced into the interlayer 7 for heating extraction. After the extraction is completed, the liquid outlet hole 63 is first opened through the liquid outlet valve to allow the extracted liquid to flow out, and then the first pressing plate 31 is driven to rotate through the first pressing plate handle 310 until the first material passing hole 311 and the water passing hole 312 on the first pressing plate 31 are no longer connected to the second material passing hole 321 on the second pressing plate 32. At this time, water is added to the containing chamber 322, which can make the containing chamber 322 move downward under the action of gravity, squeeze out the extracted liquid remaining on the material, and effectively recover the liquid. After the extraction liquid is collected, the second pressing plate 32 is rotated by rotating the second pressing plate handle 320, and the hook 323 on the second pressing plate 32 is connected to the hook hole 22 on the filter plate 2. Then, the second pressing plate handle 320 is pulled up to lift the second pressing plate 32, and the filter plate body 25 is turned over, so that the material in the extraction chamber 5 falls downward. At this time, the first pressing plate 31 can be driven to rotate by the first pressing plate handle 310 until the first feeding hole 311 on the first pressing plate 31 is connected to the second feeding hole 321 on the second pressing plate 32, so that water is added to rinse the filter plate 2, and the material residue can flow out from the liquid outlet.
