DETAILED DESCRIPTION

[0038] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0039] As a preferred example, Figures 1 to 5 As shown, an embodiment of the utility model provides a filtration device for stem cell extraction, comprising a feed chamber 1, a filtration chamber 2 and a storage chamber 3, and further comprising:

[0040] The detection part is arranged above the feeding chamber 1, and the lower end of the detection part extends into the inside of the feeding chamber 1;

[0041] The stirring part is arranged at the center of the top of the feeding chamber 1, the detection part is located on one side of the stirring part, and the bottom end of the stirring part extends into the inside of the feeding chamber 1;

[0042] The vibration part is arranged to penetrate the interior of the filter cavity 2, and the bottom end is connected to the bottom of the storage cavity 3. The stirring part contacts with the top end of the vibration part when the stirring part rotates.

[0043] The detection unit comprises:

[0044] A fixing ring 22, arranged inside the detection part;

[0045] The lifting rod 23 penetrates through the interior of the fixing ring 22 and rises and falls inside the fixing ring 22;

[0046] The float 24 is fixedly connected to the bottom end of the lifting rod 23, and as the liquid level rises or falls, it drives the lifting rod 23 to rise and fall inside the detection part;

[0047] There are multiple blocking plates 25 , which are disposed around the outer wall of the lifting rod 23 .

[0048] Specifically, the mixed liquid of stem cells is poured into the interior of the feeding funnel 20, and the mixed liquid enters the feeding chamber 1. When the liquid level of the mixed liquid in the feeding chamber 1 drops, the float 24 drops accordingly, driving the lifting rod 23 to slide in the fixing ring 22, so that the lifting rod 23 drives the blocking plate 25 to separate from the filter disc 21, so that the filter disc 21 no longer blocks the mixed liquid, and the mixed liquid enters the feeding chamber 1 through the feeding pipe 19. Conversely, when the mixed liquid in the feeding chamber 1 is sufficient, the float 24 rises, and the float 24 drives the lifting rod 23 to rise, and then the blocking plate 25 contacts with the filter disc 21, and the holes of the filter disc 21 are blocked by the blocking plate 25, and the mixed liquid no longer enters the feeding pipe 19, thereby realizing the function of automatic feeding.

[0049] As a preferred example, Figures 1 to 5 As shown, an embodiment of the utility model provides that the stirring part includes:

[0050] A driving motor 10 is arranged above the feeding chamber 1;

[0051] The stirring rod 11 is arranged inside the feeding chamber 1 and is fixedly connected to the output end of the driving motor 10;

[0052] There are a plurality of stirring blades 12 which are mounted around the outer wall of the stirring rod 11 and are inclined at 45 degrees.

[0053] The vibration part includes a lifting component and an impact component. There are multiple impact components, which are evenly distributed on the outer wall of the lifting component. The top end of the lifting component contacts the stirring blade 12, and the bottom end of the lifting component extends into the interior of the storage chamber 3.

[0054] The lifting assembly comprises:

[0055] A return spring 15 is arranged on the inner bottom wall of the storage chamber 3;

[0056] The bottom end of the slide bar 16 is connected to the top of the return spring 15 , and the top end is located below the stirring blade 12 and contacts the lower surface of the stirring blade 12 .

[0057] The inner wall of the filter chamber 2 is provided with a plurality of filter plates 13, the impact assembly is located below the filter plate 13, the top of the filter plate 13 is provided with a plurality of filter holes 14 with the same aperture, and the slide rod 16 is located inside one of the filter holes 14.

[0060] The striking rods 18 , which are provided in plurality, are fixedly mounted on the top of the fixing plate 17 .

[0061] Specifically, the mixed liquid enters the feed chamber 1, and the driving motor 10 drives the stirring rod 11 and the stirring blades 12 to rotate. The stirring blades 12 stir the mixed liquid evenly and then transport it to the filter chamber 2 for multi-stage filtration. During the filtration process, one group of stirring blades 12 rotates and squeezes the slide bar 16. The slide bar 16 is squeezed and drops, driving the return spring 15 to contract. At this time, the slide bar 16 drives the fixed plate 17 and the impact rod 18 to drop. Then the slide bar 16 passes over a group of stirring blades 12. When it is located between the two groups of stirring blades 12, the return spring 15 drives the slide bar 16 to rise. At this time, the fixed plate 17 and the impact rod 18 rise accordingly. The impact rod 18 hits the bottom of the filter plate 13, causing the filter plate 13 to vibrate. The vibration of the filter plate 13 can prevent impurities from accumulating in the filter holes 14, thereby causing the filter holes to be blocked.

[0062] As a preferred example, Figures 1 to 5 As shown, an embodiment of the utility model provides that four mounting plates 7 are installed on the outer wall of the feed chamber 1, a cover plate 9 is placed on the top of the feed chamber 1, and a drive motor 10 is fixedly installed at the center position of the cover plate 9.

[0064] A feed pipe 19 is installed through the top of the cover plate 9, a feed funnel 20 is placed on the top of the feed pipe 19, a discharge pipe 5 is installed through the outer wall of the storage chamber 3, a switch 6 is installed on the outer wall of the discharge pipe 5, a mounting hole 8 is provided on the top of the mounting plate 7, a fixing ring 22 is installed inside the feed pipe 19, a filter disc 21 is installed inside the feed pipe 19, and the circular hole on the filter disc 21 has the same diameter as the blocking plate 15

[0065] Specifically, the device is installed through the mounting plate 7 and the mounting hole 8, the cover plate 9 can prevent dust and impurities from entering the feed chamber 1, the anti-slip plate 4 can prevent the device from sliding, and the liquid after filtering can be discharged and collected through the discharge pipe 5 and the switch 6.

[0066] Working principle: the mixed liquid of stem cells is poured into the interior of the feed funnel 20, and the mixed liquid enters the feed chamber 1. The driving motor 10 drives the stirring rod 11 and the stirring blade 12 to rotate. The stirring blade 12 stirs the mixed liquid evenly, and then transports it to the filter chamber 2 for multi-stage filtration. After the filtration is completed, the liquid can be discharged and collected through the discharge pipe 5 and the switch 6.

[0067] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
