[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0022] Please see Figures 1-11 The present invention provides a technical solution: a fecal collector for use in a laboratory, comprising an operating cylinder 1, an upper mounting cavity 10 on the top wall of the operating cylinder 1, a lower mounting cavity 11 on the bottom wall of the operating cylinder 1, a lifting component 2 installed inside the upper mounting cavity 10, an abutment component 3 installed on the inner side wall of the lower mounting cavity 11, a rounded corner 12 on the bottom inner wall of the lower mounting cavity 11, and a collection component 4 screwed to the bottom end of the lifting component 2; The collection component 4 includes a collection box 41, a slide block 49 is slidably installed on the inner wall of the collection box 41, a piston 410 is installed on the bottom wall of the slide block 49, a square rod 42 is fixedly installed on the top wall of the slide block 49, a screw groove 43 is opened on the top wall of the square rod 42, a collection hopper 46 is opened on the bottom wall of the collection box 41, a suction tube 47 is connected to the bottom end of the collection hopper 46, and a rubber sealing sleeve 48 is sleeved on the bottom of the outer wall of the collection box 41. The specifications of the collection box 41 match the inner wall of the lower mounting cavity 11.

[0023] In this embodiment, the collection component 4 is mainly set up by extraction. The fecal sample is drawn into the collection box 41 for independent storage. The collection box 41 is sealed with a rubber sealing sleeve 48 to prevent the fecal sample inside the collection box 41 from contacting the outside and causing contamination. The collection box 41 can be quickly disassembled and assembled by the cooperation of the square rod 42, the screw groove 43 and the stud 28, which facilitates continuous fecal sample collection. When the sample is extracted, the square rod 42 drives the slide 49 and the piston 410 to slide upward in the collection box 41. The fecal sample enters the collection hopper 46 and the collection box 41 through the suction tube 47 and is sealed by the rubber sealing sleeve 48. After the collection is completed, the collection box 41 is removed. When the fecal sample needs to be removed, the rubber sealing sleeve 48 is removed from the collection box 41, and the square rod 42 drives the slide 49 and the piston 410 to slide downward in the collection box 41. Then the fecal sample inside is discharged from the suction tube 47 for testing.

[0024] Specifically, the outer wall of piston 410 is slidably connected to the inner wall of collection box 41, the inner wall of screw groove 43 is screwed and fixed to the outer wall of lifting assembly 2, and the top of square rod 42 slides through collection box 41 and fits against the bottom wall of lifting assembly 2 through a leak-proof rubber sleeve.

[0025] In this embodiment, when the piston 410 slides upward in the inner wall of the collection box 41, the feces will enter the inside of the collection box 41; conversely, the feces will be discharged from the collection box 41. The lifting component 2 can drive the square rod 42 to move up and down.

[0026] Specifically, a transparent observation window 44 is installed on the front wall of the collection box 41, and a scale line 45 is opened on the front wall of the collection box 41. The inner wall of the rubber sealing sleeve 48 is in contact with the outer wall of the collection box 41, the collection hopper 46 and the suction tube 47.

[0027] In this embodiment, the state of feces inside the collection box 41 can be seen through the transparent observation window 44, and the feces volume inside the collection box 41 can be known through the scale line 45. The rubber sealing sleeve 48 is mainly used to seal the collection box 41, the collection hopper 46 and the suction tube 47.

[0028] Specifically, the lifting assembly 2 includes a servo motor 22, which is fixedly installed on the top wall of the operating cylinder 1. A cross groove 21 is provided inside the lower mounting cavity 11. A sliding seat 25 is slidably installed on the inner wall of the cross groove 21. A slider 26 is fixedly installed on the outer wall of the sliding seat 25 at a position corresponding to the cross groove 21.

[0029] In this embodiment, when the sliding seat 25 moves up and down, it will drive the slider 26 to slide in the inner wall of the corresponding cross groove 21, so as to prevent the sliding seat 25 from shifting position.

[0030] Specifically, the power shaft of the servo motor 22 is fixedly installed with an adjusting screw 23 through the bearing through the operating cylinder 1. The bottom end of the adjusting screw 23 is screwed through the corresponding slider 26 and rotatably connected to the rear part of the inner wall of the cross groove 21. A positioning rod 24 is fixedly installed on the front part of the inner wall of the cross groove 21. The outer wall of the positioning rod 24 slides through the corresponding slider 26.

[0031] In this embodiment, the servo motor 22 can drive the adjusting screw 23 to rotate, thereby causing the corresponding slider 26 to slide upward along the adjusting screw 23 on the inner wall of the cross groove 21, thereby causing the sliding seat 25 to slide in the upper mounting cavity 10. At the same time, the slider 26 located at the front slides along the outer wall of the positioning rod 24, mainly to limit the slider 26.

[0032] Specifically, an extension rod 27 is fixedly installed on the bottom wall of the sliding seat 25. The bottom wall of the extension rod 27 is in contact with the top wall of the square rod 42. A stud 28 is fixedly installed at the bottom end of the extension rod 27. The outer wall of the stud 28 is screwed to the inner wall of the screw groove 43.

[0033] In this embodiment, when the sliding seat 25 is in motion, it will drive the extension rod 27 and the square rod 42 to move up and down. When the extension rod 27 and the square rod 42 are in motion, they will drive the stud 28 and the collection box 41 to move.

[0034] Specifically, the abutting component 3 includes two abutting springs 31, which are arranged symmetrically on the left and right. Each inner wall of the lower mounting cavity 11 has a limiting cavity 35, and the inner walls of the two limiting cavities 35 are fixedly connected to the corresponding abutting springs 31. Each outer wall of the two limiting cavities 35 has a passage 36, and each inner wall of the two limiting cavities 35 has a limiting block 32 slidably installed. The side walls of the two limiting blocks 32 are fixedly connected to the corresponding abutting springs 31.

[0035] In this embodiment, the abutting component 3 is mainly provided by the abutting spring 31 abutting the limiting block 32 in the inner wall of the limiting cavity 35 to receive the force.

[0036] Specifically, each of the two limiting blocks 32 has a pass seat 37 fixedly installed on its side wall and at the position corresponding to the pass opening 36. The outer wall of each pass seat 37 is in contact with the inner wall of the corresponding pass opening 36, and a triangular abutment seat 33 is fixedly installed on the side wall of each pass seat 37.

[0037] In this implementation scheme, when the limiting block 32 is subjected to force, it will drive the through seat 37 to pass through the through port 36 and drive the triangular abutment seat 33 to move.

[0038] Specifically, a triangular abutment groove 34 is provided on the outer wall of the collection box 41 at the position corresponding to the triangular abutment seat 33, and the inner wall of the two triangular abutment grooves 34 is in contact with the outer wall of the corresponding triangular abutment seat 33.

[0039] In this embodiment, the triangular abutment seat 33 abuts into the interior of the triangular abutment groove 34, thereby abutting and fixing the collection box 41 to prevent the collection box 41 from falling off and shaking when collecting samples.

[0040] Specifically, a protective cover 6 is fixedly installed on the top wall of the operating cylinder 1, a battery 8 is fixedly installed on the inner top wall of the protective cover 6, a handle 5 is fixedly installed on the top wall of the protective cover 6, an installation sleeve 7 is fixedly installed on the outer wall of the protective cover 6, the installation sleeve 7 is fixedly installed on the top of the outer wall of the operating cylinder 1 by several fastening bolts, and a lifting controller 9 is installed on the top wall of the protective cover 6.

[0041] In this embodiment, the battery 8 is mainly installed at the top of the operating cylinder 1 through the cooperation of the protective cover 6 and the mounting sleeve 7. At the same time, the handle 5 is mainly used to control the movement of the entire device, and through the cooperation of the lifting controller 9 and the battery 8, it can control the servo motor 22 to rotate forward or backward.

[0042] During operation, the lifting controller 9 and the battery 8 are first electrically connected to the servo motor 22. When the feces are sampled, the staff put on medical gloves. Before sampling, the rubber sealing sleeve 48 is fitted on the outside of the collection box 41, the collection hopper 46 and the suction tube 47. Then, the movable collection box 41 drives the square rod 42 to be screwed and fixed to the stud 28 at the bottom of the extension rod 27 through the screw groove 43, so that the top wall of the square rod 42 is in contact with the bottom wall of the extension rod 27. Turn on the lifting controller 9 switch, then press the lift button on the lifting controller 9. The servo motor 22 drives the adjusting screw 23 to rotate slowly. When the adjusting screw 23 rotates, it will drive the corresponding slider 26 to slide upward along the outer wall of the adjusting screw 23 in the inner wall of the cross groove 21. The slider 26 drives the sliding seat 25 to slide upward in the inner wall of the upper mounting cavity 10. The sliding seat 25 simultaneously drives the front slider 26 to slide upward along the outer wall of the positioning rod 24 in the inner wall of the cross groove 21. Then the sliders 26 on the left and right sides slide in the inner wall of the cross groove 21. When the sliding seat 25 moves upward, it will drive the extension rod 27 and the square rod 42 to move upward. When the square rod 42 continues to move upward, it will drive the collection box 41, the collection hopper 46 and the suction tube 47 to slowly enter the lower mounting cavity 11. After the collection box 41 enters the lower mounting cavity 11, it abuts against the triangular abutment seat 33 and drives the through seat 37 through the through port 36 into the limiting cavity 35. The through seat 37 drives the limiting block 32 into the limiting cavity 35 and compresses the abutment spring 31. When the triangular abutment groove 34 moves to the position corresponding to the triangular abutment seat 33, the elastic action of the abutment spring 31 pushes the limiting block 32 to slide in the inner wall of the limiting cavity 35, thereby driving the through seat 37 through the through port 36 to drive the triangular abutment seat 33 to abut against and fix the triangular abutment groove 34. When the triangular abutment seat 33 enters the triangular abutment groove 34 and contacts, a click will be made. At this time, the top wall of the collection box 41 is in contact with the inner top wall of the lower mounting cavity 11. After the lifting controller 9 is turned off and the rubber sealing sleeve 48 is removed from the outer wall of the collection box 41, the operating cylinder 1 and the collection component 4 are moved downward by the handle 5, and the suction tube 47 is lowered into the fecal sample. Then the lifting controller 9 is turned on and the up button of the lifting controller 9 is pressed. Then, the servo motor 22 drives the adjusting screw 23 to rotate slowly. When the adjusting screw 23 rotates, it will drive the corresponding slider 26 to slide upward along the outer wall of the adjusting screw 23 in the inner wall of the cross groove 21. The slider 26 drives the sliding seat 25 to slide upward in the inner wall of the upper mounting cavity 10. The sliding seat 25 simultaneously drives the front slider 26 to slide upward along the outer wall of the positioning rod 24 in the inner wall of the cross groove 21. Then, the sliders 26 on the left and right sides slide in the inner wall of the cross groove 21. When the sliding seat 25 moves upward, it will drive the extension rod 27 and the square rod 42 to move upward. When the square rod 42 continues to move upward, it will cause the top wall of the collection box 41 to abut against the inner top wall of the lower mounting cavity 11. When the square rod 42 continues to move upward, it will drive the sliding seat 49 and the piston 410 to slide upward in the inner wall of the collection box 41. Then, the suction tube 47 inserted into the feces will suck the fecal sample into the collection box 41 and the collection hopper 46 for storage. The handle 5 moves the operating cylinder 1 and the collection component 4 upward, inserting the collection hopper 46 and suction tube 47 at the bottom of the collection box 41 into the rubber sealing sleeve 48, quickly achieving a complete seal of the suction tube 47, collection hopper 46 and the bottom of the collection box 41. Next, by pressing the descent button on the lifting controller 9, the servo motor 22 drives the adjusting screw 23 to rotate slowly. When the adjusting screw 23 rotates, it will drive the corresponding slider 26 to slide down along the outer wall of the adjusting screw 23 in the inner wall of the cross groove 21. The slider 26 drives the sliding seat 25 to slide down in the inner wall of the upper mounting cavity 10. The sliding seat 25 simultaneously drives the front slider 26 to slide down along the outer wall of the positioning rod 24 in the inner wall of the cross groove 21. Then, the sliders 26 on the left and right sides slide in the inner wall of the cross groove 21. When the sliding seat 25 moves down, it will drive the extension rod 27 and the square rod 42 to move down. As the square rod 42 continues to move downwards, the collection box 41 gradually disengages from the contact state with the top wall of the lower mounting cavity 11. As the collection box 41 continues to move downwards, it will cause the triangular contact seat 33 to disengage from the contact state with the triangular contact groove 34, and drive the through seat 37 through the through port 36 into the limiting cavity 35. After the through seat 37 drives the limiting block 32 into the limiting cavity 35, it compresses the contact spring 31. The collection box 41 gradually disengages from the interior of the lower mounting cavity 11. Then, the moving collection box 41 drives the square rod 42 to disengage from the screw position of the stud 28 at the bottom of the extension rod 27 through the screw groove 43, thereby removing the collection box 41 to complete the fecal sampling. The fecal sample content inside the collection box 41 can be seen through the transparent observation window 44 and the scale line 45, and the fecal sample inside the collection box 41 can be transferred.
