All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 7, the present invention relates to an automatic fat separating filter, which includes: cup 10, particulate filter 20, holder 30, macro filter 40, and lid 50. The particulate filter 20 is located in the bowl 10 and detachably fitted to an inner wall of the bowl 10, and the particulate filter 20 constitutes a first filtering chamber a with the bowl 10 and serves to separate oil and water in fat. One end of the holder 30 is detachably fitted to the particulate filter 20. The macroparticle filter 40 is fixed at the other end of the bracket 30 and is positioned in the outline range of the cup cover 50, and the macroparticle filter 40 and the cup cover 50 form a second filter chamber b for separating fascia in fat. The cup body 10 is provided with a first switch valve 11 communicated with the first filter cavity a, and the cup cover 50 is provided with a second switch valve 51 and a cleaning pipe 52 which are communicated with the second filter cavity b. Lid 50 covers cup 10 and seals cup 10. Based on the above structure, in the use of the automatic fat separation filter of the present embodiment, the holder 30 to which the macro-filter 40 is attached is first assembled to the micro-filter 20; then the whole body formed by the bracket 30 and the particulate filter 20 is arranged in the cup body 10; finally, the cup cover 50 is covered on the cup body 10. In the using process, the first switch valve 11 is closed, and the second switch valve 51 is connected to the liposuction machine after being opened; using a liposuction machine to extract fat into the second filtering cavity b; after the fat enters the second filter chamber b, the fascia is blocked in the second filter chamber b by using the large particle filter 40, and the fat, oil, water and the like move towards the particulate filter 20; using the particulate filter 20, the fat is blocked inside the particulate filter 20, while the oil, water, etc. enter the first filter chamber a; closing the second switch valve 51 and opening the cup cover 50, bringing out fascia adhered to the cup cover 50 when opening the cup cover 50, cleaning the cup cover 50 and then covering the cup cover 50 on the cup body 10; then, cleaning liquid is injected into the cleaning pipe 52, and the cleaning liquid flows into the particulate filter 20 to clean fat and carry impurities into the first filter chamber a; opening the first switch valve 11 and connecting to a negative pressure machine, and sucking out the mixture of oil, water, impurities and the like in the first filter cavity a by the negative pressure machine; only pure fat remains in the particulate filter 20; finally, the liposuction machine is connected to the washing tube 52 to suck the fat, so that the purified fat can be obtained. Based on this, in two steps to fat filtration and washing, bowl cover 50 seals the cup 10 all the time to can prevent that fat from contacting the air for a long time and leading to being polluted, and then reduced the risk that the human body is infected in carrying out fat transplantation in-process. Meanwhile, the particle filter 20, the bracket 30, the cup body 10 and the cup cover 50 are detachably arranged, so that after the filtering is finished, all the parts can be detached and cleaned one by one, and the problem that the device is complex and cannot be completely cleaned is solved.

In order to facilitate the extraction of fat from the washing pipe 52, the second filtering chamber b of the present embodiment is protruded toward a side close to the washing pipe 52. Therefore, when the washing pipe 52 is used to extract fat, the fat can be gathered toward the washing pipe 52 along the inner wall of the second filtering chamber b, thereby facilitating the extraction of the fat by the washing pipe 52. Meanwhile, in order to enhance the effect of the washing pipe 52 for extracting fat, the washing pipe 52 may be disposed at the center of the protrusion of the second filtering chamber b.

In order to secure the structure of the particulate filter 20, the particulate filter 20 of the present embodiment includes: the filter cartridge 21 and the fixing ring 22 are coaxially distributed with the cup body 10, the outer peripheral wall and the outer bottom surface of the filter cartridge 21 and the inner peripheral wall and the inner bottom surface of the cup body 10 form a first filter chamber a, one end of the filter cartridge 21, which is close to the macro-particulate filter 40, is provided with an inlet communicated with the macro-particulate filter 40, a cleaning chamber c is arranged in the filter cartridge 21, the peripheral side of the cleaning chamber c is provided with a first filter hole d, the cleaning chamber c is communicated with the first filter chamber a through the first filter hole d, and the aperture of the first filter hole d is larger than that of oil and water and smaller; the fixed ring 22 is fixedly sleeved on the outer peripheral wall of the filter cylinder 21, the fixed ring 22 and the cup body 10 are coaxially distributed, and the outer peripheral wall of the fixed ring 22 is abutted to the inner peripheral wall of the cup body 10. Based on the structure, fat enters the cleaning cavity c from the inlet after being filtered for the first time by the large particle filter 40; since the first filtering hole d has a diameter larger than that of the oil and water and smaller than that of the fat, the oil-water mixture in the fat enters the first filtering chamber a through the first filtering hole d, and the fat remains in the cleaning chamber c. Meanwhile, the fixing ring 22 is arranged, so that on one hand, the filter cartridge 21 can be assembled in the cup body 10 through the characteristics that the fixing ring 22 and the cup body 10 are coaxially distributed and abutted; on the other hand, by arranging the fixing ring 22, the direct communication relationship between the macroparticle filter 40 and the first filtering chamber a can be isolated, and the loss caused by the fat directly falling into the first filtering chamber a can be avoided.

In order to ensure that the first filter chamber a has a reasonable space, a limiting table 12 for limiting the fixing ring 22 is fixedly arranged on the inner wall of the cup body 10. Based on above structure, through set up spacing platform 12 on the inner wall at cup 10, can drive solid fixed ring 22 and move together in pegging graft cartridge filter 21 cup 10, and when solid fixed ring 22 spacing platform 12 butt, spacing platform 12 can hinder solid fixed ring 22 and continue to move to can prevent cartridge filter 21 to continue to peg graft, and then can guarantee that first filter chamber a possesses reasonable space size.

To facilitate assembly of the holder 30 to the particulate filter 20, the holder 30 of the present embodiment includes: the fixing ring 22 is provided with a base 31 which is erected on the fixing ring 22 and is provided with a through hole, and a connecting column 32 which is fixed on the base 31 and is used for connecting the macro-particle filter 40, and the fixing ring 22 is provided with a limit groove e which is matched with the base 31 and is opposite to the base 31. Based on the above structure, the support 30 is provided with the base 31 and the support 30, and the fixing ring 22 is provided with the limiting groove e, so that the support 30 can be prevented from shaking when the base 31 is provided with the limiting groove e, and the filtering error caused by the instability of the large particle filter 40 can be avoided.

In order to ensure the action effect of the macro-particulate filter 40, the macro-particulate filter 40 of the embodiment is configured as a filter disc provided with a second filter hole f, the filter disc is coaxially distributed with the cup cover 50 and is abutted against the inner wall of the cup cover 50, and the aperture of the second filter hole f is larger than fat and smaller than fascia. Based on the above structure, the fat enters the second filtering chamber b, because the aperture of the second filtering hole f is larger than the fat and smaller than the fascia, the fat, oil, water, etc. will enter the filtering cylinder 21 through the second filtering hole f, and the fascia will remain in the second filtering chamber b. Meanwhile, the filter disc is arranged to be coaxially distributed with the cup cover 50 and abutted against the inner wall of the cup cover 50, so that a gap between the filter disc and the cup cover 50 can be eliminated, and fascia is prevented from entering the filter cartridge 21.

In order to observe the fat filtering process directly from the outside, the cup body 10 and the lid 50 of the present embodiment are made of transparent materials. Based on the above structure, since the cup body 10 and the cup lid 50 are both made of transparent materials, the separation condition of the particulate filter 20 and the macro filter 40 can be directly observed from the outside, and the adjustment can be performed in time when the problem of filtration is found from the outside.

To facilitate assembly of lid 50 to cup 10, the present embodiment preferably includes a threaded connection between cup 10 and lid 50.

In order to measure the amount of fat in the particulate filter 20, the cup body 10 of this embodiment is provided with volume scale marks (not shown). Based on the above structure, when the bowl 10 is made of a transparent material, the fat in the particulate filter 20 can be directly observed through the bowl 10. Thus, the volume of fat in the particulate filter 20 (the amount of fat can be obtained by a conversion formula of volume and mass) can be directly obtained by providing the volume scale marks, thereby facilitating control of the amount of fat used in use.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
