[0024] like Figure 1-7 A filter device 100 is provided, wherein a filter cavity 103 is formed in the filter device 100, a liquid inlet 101 and a liquid outlet 102 are provided on the filter device 100, a first filter channel 21 is formed in the filter cavity 103 and between the liquid inlet 101 and the liquid outlet 102, a filter disc 3 and a cleaning member 4 are provided on the first filter channel 21, a filter hole is provided on the filter disc 3, the cleaning member 4 comprises a connecting piece 41 and a cleaning needle 42 at one end close to the filter disc 3, the cleaning needle 42 extends from the connecting piece 41 toward the filter hole, and the cleaning member 4 can move close to or away from the filter disc 3, so that when the cleaning member 4 approaches the filter disc 3, the cleaning needle 42 extends into the filter hole 31 to clean the filter hole 31.

[0025] The utility model provides a filtering device 100, wherein a fruit juice beverage containing residue enters a filter chamber 103 from a liquid inlet 101, and after being filtered by a filter disc 3 of a first filtering channel 21, the residue is intercepted, and the filtered juice flows out from a liquid outlet 102, and the entering liquid can be filtered. When a connecting piece 41 moves close to the filter disc 3, the movement of the filter disc 3 drives a cleaning needle 42 thereon to move toward a filter hole 31 close to the filter disc 3, so as to clean impurities blocking the filter hole, and effectively prevent the impurities from blocking the filter hole, so that the filter disc 3 can filter continuously, ensure the filtering effect of the filtering device 100, and ensure production efficiency.

[0026] And in some embodiments, the diameter of the cleaning needle 42 is much smaller than the diameter of the filter hole.

[0027] A mounting chain 51 and a mounting frame 52 are provided in the filter chamber 103 . The mounting frame 52 is connected to the inner wall of the filter chamber 103 . A mounting hole 521 is provided on the mounting frame 52 . The mounting chain 51 is inserted into the mounting hole 521 .

[0028] In this embodiment, the mounting frame 52 is connected to the inner wall of the filter chamber 103, and the mounting frame 52 is provided with a mounting hole 521 and a water hole 522. The mounting chain 51 passes through the mounting hole 521. Since the mounting chain 51 passes through the mounting hole 521, the mounting chain 51 can be displaced in the filter chamber 103 under certain conditions. The water hole 522 on the mounting frame 52 can ensure the passage of liquid.

[0029] The mounting chain 51 includes a first chain and a second chain, the first chain and the second chain are detachably connected via a first nut 61 and a second nut, and the first nut 61 is between the filter disc 3 and the cleaning member 4 .

[0030] In this embodiment, a first nut and a second nut are provided on the first chain, and a thread connected to the first nut and the second nut is provided on the second chain. The threads on the second chain are respectively connected to the first nut and the second nut to form an installation chain.

[0031] The connecting piece 41 extends toward the filter 3 to form a mounting cavity 411 , in which a spring 412 is disposed. One end of the spring 412 abuts against the first nut 61 , and the other end abuts against the connecting piece 41 .

[0032] In this embodiment, the installation cavity 411 forms an opening toward one end of the filter plate 3 .

[0033] When the connecting plate 41 moves close to the filter plate 3, the first nut 61 extends into the installation cavity 411, presses the spring 412, and causes the spring 412 to undergo elastic deformation. At this time, the cleaning needle 42 approaches the filter plate 3, so that the cleaning needle 42 can extend into the filter hole on the filter plate 3 to clean the filter hole.

[0034] In this embodiment, the extension length of the installation cavity is smaller than the extension length of the cleaning needle.

[0035] The first fixing member 71 is further included. The first fixing member 71 is installed on the installation chain 51 and abuts against the connecting piece 41 . The first fixing member 71 is used to limit the movement of the connecting piece 41 .

[0036] In this embodiment, the first fixing member 71 limits the cleaning member 4 from moving or rotating on the mounting chain 51 in a counterclockwise direction relative to the mounting chain 51 .

[0037] It also includes a filter cartridge 8 . A second filter channel 22 is formed in the filter cavity 103 and between the liquid inlet 101 and the liquid outlet 102 . The filter cartridge 8 is arranged in the second filter channel 22 , and the filter cartridge 8 is installed on the installation chain 51 .

[0038] In this embodiment, a filtering hole is provided on the filter cartridge 8, and the fruit juice beverage containing residue enters the filter chamber 103 from the liquid inlet 101. After being filtered by the filter cartridge 8 of the second filter channel 22, the filtering hole intercepts the residue, and the filtered juice flows out from the liquid outlet 102, which can effectively filter the incoming liquid.

[0039] The filter disc 3 is located at one end of the first filter channel 21 close to the liquid inlet 101 , and the filter cartridge 8 is located at one end of the second filter channel 22 far from the liquid inlet 101 .

[0040] The second fixing member 72 is also included, and the second fixing member 72 is installed on the installation chain 51 and abuts against the filter cartridge 8 to limit the filter cartridge 8 from rotating on the installation chain 51 in a clockwise direction relative to the installation chain 51 .

[0041] The second nut is located at one end close to the filter cartridge 8 , and the filter cartridge 8 is between the second nut and the second fixing member 72 to fix the position of the filter cartridge 8 on the mounting chain 51 .

[0042] In this embodiment, the filter device 100 is in a ring shape, and the cross section of the filter cavity 103 is circular.

[0043] In this embodiment, the filter device 100 includes a first filter part 1031 and a second filter part 1032, and the first filter part 1031 and the second filter part 1032 are detachably connected via a first clamp 105 and a second clamp 106, so that when the first filter part 1031 and the second filter part 1032 are separated by the first clamp 105 and the second clamp 106, a filter disc 3, a cleaning needle 42, a filter cartridge 8 and other structures can be loaded into the filter chamber 103.

[0044] In this embodiment, the fruit juice beverage containing residue enters the filter cavity 103 from the liquid inlet 101. Since the filter disc 3 is close to the liquid inlet 101, most of the fruit juice beverage containing residue enters the second filter channel 22, and flows out from the liquid outlet 102 after being filtered by the filter cartridge 8; a small part enters the first filter channel 21, and flows out from the liquid outlet 102 after being filtered by the filter disc 3. Since the fruit juice beverage contains residue, when more fruit juice beverage enters the second filter cavity 103, the residue may block the filtering holes on the filter cartridge 8. When the residue blocks the filtering holes on the filter cartridge 8, the fruit juice beverage containing the residue can only be filtered through the filter plate 3 of the first filter channel 21, and when the residue may block the filtering holes on the filter cartridge 8, the juice entering the second filter channel 22 will push the blocked filter cartridge 8 to drive the mounting chain 51 to move in the clockwise direction, so that the cleaning needle 42 on the cleaning member 4 moves toward the filter plate 3 to clean the filter holes on the filter plate 3, thereby ensuring the filtering effect of the filter plate 3.

[0045] When the production is finished, the filter device 100 can be disassembled through the clamp, and the filter cartridge 8 and filter disc 3 inside can be taken out and rinsed, so that the juice residue on the filter cartridge 8 and filter disc 3 can be cleaned for the next filtration. Two filtration channels are set, and the filter disc is cleaned by a cleaning needle to ensure the effective filtration of the filter disc in one production and the smooth progress of one production.

[0046] The above-mentioned preferred implementation modes should be regarded as illustrative examples of the implementation modes of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on this scheme should be regarded as within the scope of protection of this patent.
