A motor for driving the cam rod to rotate is installed inside the cover, and the other end of the cam rod is rotatably connected to the inner wall of the cover. The utility model can use the rotational connection point between the filter frame and the filter box as the midpoint, and intermittently swing to the left and right sides to filter, thereby accelerating the filtration rate, improving the filtration effect, and effectively preventing the possibility of clogging of the filter holes.

[0004] In specific operations, impurities in the hyaluronic acid are filtered through a filter plate, but no cleaning device is provided on the filter plate. After long-term use, impurities accumulate and become clogged, which makes it inconvenient to clean the impurities and affects the filtering efficiency of the hyaluronic acid. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the filter plate is not provided with measures for cleaning impurities, which affects the filtering efficiency after long-term use, and to propose a hyaluronic acid filtering device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A hyaluronic acid filtering device is designed, comprising a frame, a storage box fixedly mounted on the top of the frame, a stirring device disposed inside the storage box, and a collecting chamber and a filtering assembly disposed at the bottom of the frame, the filtering assembly being used to filter the hyaluronic acid in the storage box;

[0009] Furthermore, the filter assembly also includes a motor, which is fixedly installed on the bottom of one side of the support frame. The shaft end of the motor passes through the support frame and is fixedly connected to a first connecting rod. The free end of the first connecting rod is rotatably connected to a second connecting rod, and the cleaning piece is slidably connected to the free end of the second connecting rod through the rotating rod at the top.

[0010] Furthermore, guide grooves are provided on both sides of the top of the support frame, and the cleaning piece is slidably connected in the guide grooves through the guide parts on both sides, wherein a first spring is provided on the outer periphery of the rotating rod, and the two ends of the first spring respectively resist the cleaning piece and the second connecting rod.

[0011] Furthermore, one side of the support frame is slidably connected to the abutment member through a pair of fixed rods. The abutment member is a flat plate structure and extends outward close to the side of the cleaning member. The abutment member is bent downward away from the motor side to form a bent portion. The cleaning member is slidably connected to the extended portion of the top of the abutment member through the bent portion.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 A hyaluronic acid filtering device comprises a frame 1, a storage box 2 is fixedly mounted on the top of the frame 1, a stirring device 3 is provided inside the storage box 2, and a collecting chamber 4 and a filtering assembly 5 are provided at the bottom of the frame 1, the filtering assembly 5 is used to filter the hyaluronic acid in the storage box 2;

[0023] The filter assembly 5 includes a support frame 51 , and a filter element 52 , a cleaning element 53 and a supporting element 54 are provided on the top of the support frame 51 . The cleaning element 53 and the supporting element 54 are used together to clean impurities on the filter element 52 .

[0024] It should be added that the stirring device 3 includes a driving motor fixed to the top of the frame 1, the shaft end of the driving motor extends into the frame 1 and is fixedly connected to a stirring rod, the stirring rod is arranged in the storage box 2, and a plurality of stirring rollers are fixedly connected to the periphery of the stirring rod, which accelerates the filtration efficiency of the hyaluronic acid by stirring;

[0025] Among them, the top of the frame 1 is connected to a feed pipe, and a sealing plate is hinged and rotatable at the bottom of the frame 1, which is used to close the collection chamber 4. A collection box is placed inside the collection chamber 4 below the filter element 52.

[0026] Furthermore, the filter assembly 5 also includes a motor 55, and the motor 55 is fixedly installed on the bottom of one side of the support frame 51. The axial end of the motor 55 passes through the support frame 51 and is fixedly connected to a first connecting rod 56. The free end of the first connecting rod 56 is rotatably connected to a second connecting rod 57, and the cleaning piece 53 is slidably connected to the free end of the second connecting rod 57 through the rotating rod 571 at the top.

[0027] It should be noted that an installation area is provided between one side of the support frame 51 and the filter element 52, and the motor 55 is fixedly connected to the bottom of the installation area. Of course, the discharge pipe at the bottom of the storage box 2 is provided above the filter element 52 to prevent hyaluronic acid from contaminating the installation area.

[0028] Furthermore, guide grooves 511 are provided on both sides of the top of the support frame 51, and the cleaning piece 53 is slidably connected in the guide grooves 511 through the guide parts 531 on both sides, wherein the outer periphery of the rotating rod 571 is provided with a first spring 572, and the two ends of the first spring 572 respectively resist the cleaning piece 53 and the second connecting rod 57.

[0029] It should be noted that the motor 55 drives the first connecting rod 56 to rotate half a circle to prevent the second connecting rod 57 from interfering with the inner wall of the frame 1 when rotating. In specific operation, the motor 55 drives the first connecting rod 56 to drive the second connecting rod 57 to rotate. Since the two sides of the cleaning member 53 slide with the support frame 51 through the guide portion 531, the cleaning member 53 is driven by the second connecting rod 57 to reciprocate.

[0030] The cleaning member 53 includes a support plate, the top of which is fixedly connected to the rotating rod 571, and the bottom of which is fixedly connected to a cleaning brush, which contacts the filter 52, which is a filter screen or a filter plate.

[0031] In addition, after the cleaning member 53 is reset, the first connecting rod 56 and the second connecting rod 57 are arranged at an angle to avoid overlapping with each other and failing to drive the cleaning member 53 to move.

[0032] In more detail, one side of the support frame 51 is slidably connected to the abutment 54 through a pair of fixed rods 512. The abutment 54 is a flat plate structure and extends outward close to the side of the cleaning member 53. The abutment 54 is bent downward away from the side of the motor 55 to form a bending portion 541. The cleaning member 53 is slidably connected to the extended portion of the top of the abutment 54 through the bending portion 541.

[0033] In general, a protrusion is provided on the top of the fixing rod 512 and is sleeved with a second spring 513 , and two ends of the second spring 513 respectively abut against the protrusion and the abutting member 54 .

[0034] It is worth mentioning that Figure 4 As shown, because the bent portion 541 abuts against the support frame 51, a gap is formed between the side of the abutting member 54 facing away from the bent portion 541 and the support frame 51, and one end of the cleaning member 53 is disposed within the gap;

[0035] When the cleaning member 53 moves to the other side, the bent portion 541 contacts and slides against the cleaning member 53 through the fixing rod 512 and the second spring 513. When the cleaning member 53 is reset, the guide slope on the other side contacts and slides above the abutting member 54.

[0036] Among them, the rotating rod 571 at the top of the cleaning member 53 is slidably connected to the second connecting rod 57 to provide a movable space for the cleaning member 53. Of course, the length of the guide portion 531 is greater than the rotating rod 571 to prevent the guide portion 531 from escaping from the guide groove 511.

[0037] Finally, the bottom of the storage box 2 is a conical structure, and the bottom is located above the filter element 52 and is connected to a discharge pipe, wherein the side of the frame 1 is provided with a discharge port corresponding to the filter element 52, and a baffle 11 is inserted at the discharge port through a pair of stop blocks.

[0038] Specifically, the feed pipe is arranged above the filter element 52 and an electric valve is provided inside the feed pipe. The four sides of the support frame 51 are in contact with the inner wall of the frame 1 , and a sealing gasket is provided between the baffle 11 and the outer wall of the frame 1 .

[0039] Working mode: When working, the hyaluronic acid is transported to the storage box 2 through the feed pipe, and the storage box 2 transports the hyaluronic acid to the filter element 52 through the feed pipe for filtration. The filtered hyaluronic acid enters the collection box and can be transported out;

[0040] When a large amount of impurities accumulate on the filter element 52, the electric valve in the discharge pipe is closed to discharge the material, and then the baffle 11 is pulled out. The motor 55 drives the first connecting rod 56 to rotate half a circle, and the first connecting rod 56 drives the second connecting rod 57 to rotate. The cleaning element 53 is driven by the second connecting rod 57 and moves back and forth in coordination with the guide part 531. During the movement, the cleaning brush at the bottom is used to discharge the impurities through the discharge port.

[0041] When the cleaning member 53 moves to the other side, the bent portion 541 contacts and slides against the cleaning member 53 through the fixing rod 512 and the second spring 513. When the cleaning member 53 is reset, the guide slope on the other side contacts and slides above the abutting member 54, thereby preventing impurities from being pushed to the other side.

[0042] Finally, the baffle 11 is reinserted to close the discharge port, and filtering can be performed again.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
