[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0035] Reference Figure 1 - Fig. 9 The skin oil detection device includes an annular base 1, an L-shaped plate 15 is fixedly connected to the upper end of the annular base 1, and a detector 17 is fixedly connected to the side wall of the L-shaped plate 15, which can detect skin oil, and is a prior art.
[0036] The sample delivery mechanism includes a fixed ring 2 fixedly connected to the upper end of the annular base 1, an annular groove is provided on the upper end of the fixed ring 2, and a rotatable ring 3 (such as Figure 3 As shown), the side wall of the ring 3 is evenly distributed and rotatably connected with four shafts 4. It should be noted that friction plates are provided at the rotational connections between the four shafts 4 and the ring 3, so that the shafts 4 do not rotate without external force. The ends of the four shafts 4 away from the ring 3 are fixedly connected with a fixed frame 5, and the inner wall of the fixed frame 5 is slidably connected with an adsorption plate 6. The side wall of the adsorption plate 6 is elastically connected to the inner wall of the fixed frame 5 through a plurality of first springs 7. An adsorption groove 8 is provided on the side wall of the adsorption plate 6 away from the first spring 7. An oil-absorbing paper is provided in the adsorption groove 8 (not shown in the figure), and an adsorption mechanism for adsorbing the oil-absorbing paper is provided on the adsorption plate 6. A hollow rod 18 is rotatably connected to the upper end of the annular base 1, and the side wall of the hollow rod 18 is fixedly connected to the inner wall of the ring 3 through a plurality of fixing rods 19 (as shown in the figure). Figure 2 as shown).
[0037] The adsorption mechanism includes a cavity 9 opened in the adsorption plate 6, and the inner wall of the cavity 9 is provided with a plurality of adsorption holes 10 connected with the inner wall of the adsorption groove 8. The inner wall of the cavity 9 is fixedly connected with an exhaust pipe 12, and the side wall of the exhaust pipe 12 passes through the side wall of the rotating shaft 4 and is sealed and rotatably connected with the inner wall of the hollow rod 18.
[0038] The bottom of the annular base 1 is fixedly connected to a suction pipe 20, and the side wall of the suction pipe 20 is sealed and rotatably connected to the side wall of the hollow rod 18. Further, the suction pipe 20 is connected to an external vacuum pump, and an arc groove 21 is opened on the inner wall of the suction pipe 20 (such as Figure 5 , Figure 8 and Fig. 9 As shown), the openings of the three exhaust pipes 12 in the hollow rod 18 are all opposite to the arc groove 21, a notch 22 is provided on the side wall of the suction pipe 20 away from the arc groove 21, and the opening of another exhaust pipe 12 in the hollow rod 18 is opposite to the notch 22.
[0039] like Figure 5, Figure 8 and Fig. 9 As shown, when the pipe openings of three of the exhaust pipes 12 located in the hollow rod 18 are directly opposite to the arc groove 21, the three cavities 9 directly opposite to the three exhaust pipes 12 can be evacuated through the suction pipe 20 and the three exhaust pipes 12, so that the three cavities 9 are in a negative pressure state, thereby adsorbing and fixing the oil-absorbing paper located in the adsorption groove 8. When the pipe opening of another exhaust pipe 12 located in the hollow rod 18 is directly opposite to the groove 22, the air pressure in the cavity 9 is consistent with the external air pressure, thereby facilitating the staff to take and place the oil-absorbing paper in the adsorption groove 8 corresponding to the cavity 9.
[0040] The inner wall of the fixed frame 5 is provided with a top outlet 11, and the upper end of the L-shaped plate 15 is fixedly connected to an electric push rod 16, and the movable end of the electric push rod 16 is directly opposite to the top outlet 11 (such as Figure 1 As shown in FIG. 1 ), the electric push rod 16 is directly opposite to the detector 17.
[0041] When the electric push rod 16 is extended, pressure can be applied to the adsorption plate 6 to move downward, driving the oil-absorbing paper in the adsorption groove 8 to move downward, so that the oil-absorbing paper contacts the skin, completing automatic sampling without manual operation by staff, thus avoiding other substances adhering to the oil-absorbing paper and affecting subsequent test results.
[0042] The inner wall of the fixing ring 2 is fixedly connected with two arc-shaped bevel gear plates 13, and the side walls of the four rotating shafts 4 are fixedly connected with bevel gears 14. During the rotation process of the ring 3, the four bevel gears 14 are driven to mesh with the arc-shaped bevel gear plates 13 (such as Figure 4 as shown).
[0043] like Figure 3 and Figure 4 As shown, during use of the device, the ring 3 is intermittently rotated ninety degrees clockwise. At this time, under the action of the arc-shaped bevel gear plate 13, when the bevel gear 14 rotates and engages with the arc-shaped bevel gear plate 13 until it is separated, the bevel gear 14 rotates half a circle, thereby driving the rotating shaft 4 and the fixed frame 5 to rotate half a circle, and driving the oil-absorbing paper to rotate half a circle intermittently, so that the position of the oil-absorbing paper is automatically changed under different working conditions without manual intervention.
[0044] The squeezing mechanism is used to squeeze the grease on the oil-absorbing paper evenly. The squeezing mechanism includes a first rod 23 (such as a first rod 23) rotatably connected to the side wall of the fixing ring 2. Figure 6As shown in the figure, a U-shaped plate 24 is fixedly connected to the side wall of the first rod 23 away from the fixed ring 2. Threaded cylinders 25 are fixedly connected to both the upper and lower ends of the U-shaped plate 24. Rifled rods 26 are threadedly connected to the inner walls of the two threaded cylinders 25. Turntables 29 are fixedly connected to the side walls of the two rifled rods 26 away from each other. A plurality of pressing beads 30 are embedded in the side walls of the turntables 29 away from the rifled rods 26. Pressing plates 27 are rotatably connected to the side walls of the two rifled rods 26 close to each other. Elastic connections are made between the side walls of the two pressing plates 27 away from each other and the side wall of the U-shaped plate 24 through a plurality of second springs 28. A fixed seat 31 is fixedly connected to the upper end of the annular base 1. A cleaning cotton 32 is pasted on the upper end of the fixed seat 31 (as Figure 1 shown).
[0045] It should be noted that the upper turntable 29 faces the oil-absorbing paper, and the lower turntable 29 faces the cleaning cotton 32.
[0046] A second rod 33 is rotatably connected to the upper end of the annular base 1. A first wedge-shaped plate 34 is fixedly connected to the upper side of the side wall of the second rod 33 through a connecting rod. Second wedge-shaped plates 35 are fixedly connected to the side walls of the two pressing plates 27 close to each other. The first wedge-shaped plate 34 squeezes the two second wedge-shaped plates 35 during rotation (as Figure 6 shown).
[0047] During the rotation of the second rod 33 driving the first wedge-shaped plate 34, the two second wedge-shaped plates 35 will be intermittently squeezed, thereby intermittently squeezing the two pressing plates 27. At this time, the two pressing plates 27 move up and down under the squeezing of the first wedge-shaped plate 34 and the action of a plurality of second springs 28. Under the action of the two threaded cylinders 25, the two rifled rods 26 move in a rotational and vertical movement. When the upper rifled rod 26 moves in a rotational and vertical movement, the turntable 29 and a plurality of pressing beads 30 continuously roll on the oil-absorbing paper, making the grease distribution on the oil-absorbing paper uniform, increasing the contact area between the grease and the oil-absorbing paper, and enhancing its detection effect;
[0048] When the lower rifled rod 26 moves in a rotational and vertical movement, the turntable 29 and a plurality of pressing beads 30 continuously roll on the cleaning cotton 32, cleaning the grease on the turntable 29 and a plurality of pressing beads 30, facilitating the next use, and avoiding contamination at the same time, improving the accuracy of subsequent detection results.
[0049] A third rod 36 is rotatably connected to the upper end of the annular base 1. A first bevel gear 37 is fixedly connected to the upper end of the third rod 36. A second bevel gear 38 is fixedly connected to the side wall of the first rod 23. The first bevel gear 37 and the second bevel gear 38 are meshed with each other.
[0050] A driving mechanism is provided on the annular base 1, and the driving mechanism includes a first one-way bearing 40 and a second one-way bearing 41. The side wall of the third rod 36 is fixedly connected to the inner ring side wall of the first one-way bearing 40. A motor 39 is fixedly connected to the lower end of the annular base 1. The side wall of the movable shaft of the motor 39 is fixedly connected to the outer ring side wall of the first one-way bearing 40 through a plurality of brackets. The side wall of the third rod 36 is fixedly connected to the second gear 42, and the side wall of the hollow rod 18 is fixedly connected to the third gear 43 meshing with the second gear 42.
[0051] It should be noted that the gear ratio of the first bevel gear 37 to the second bevel gear 38 is 2:1. After the ring 3 rotates ninety degrees clockwise, the third rod 36 drives the first rod 23 to rotate half a circle through the first bevel gear 37 and the second bevel gear 38. When the first rod 23 rotates, the first wedge plate 34 is away from the two second wedge plates 35 (such as Figure 6 as shown).
[0052] The side wall of the movable shaft of the motor 39 is fixedly connected to the inner ring side wall of the second one-way bearing 41, the outer ring side wall of the second one-way bearing 41 is fixedly connected to the first wheel 44, the lower end of the second rod 33 is fixedly connected to the second wheel 45, and the first wheel 44 and the second wheel 45 are connected by a synchronous belt.
[0053] It should be noted that when the motor 39 rotates counterclockwise, the outer ring of the first one-way bearing 40 drives its inner ring to rotate, and the inner ring of the second one-way bearing 41 does not drive its outer ring to rotate. When the motor 39 rotates clockwise, the outer ring of the first one-way bearing 40 does not drive its inner ring to rotate, and the inner ring of the second one-way bearing 41 drives its outer ring to rotate.
[0054] When sampling and testing skin oil, first put the oil-absorbing paper in the adsorption groove 8 opposite to the notch 22, then drive the motor 39 to rotate counterclockwise, drive the outer ring of the first one-way bearing 40 to drive its inner ring to rotate, and then the third rod 36 drives the hollow rod 18 to rotate ninety degrees clockwise through the second gear 42 and the third gear 43, and the hollow rod 18 drives the ring 3 to rotate ninety degrees clockwise through multiple fixed rods 19, and drives the four rotating shafts 4 to rotate ninety degrees. Under the action of the arc-shaped bevel gear plate 13, when the bevel gear 14 located on the rotating shaft 4 rotates and meshes with the arc-shaped bevel gear plate 13 until it separates, the bevel gear 14 rotates half a circle, and then drives the rotating shaft 4 and the fixed frame 5 to rotate half a circle, and drives the oil-absorbing paper to rotate half a circle and then be located below, so that the top outlet 11 on the fixed frame 5 is opposite to the electric push rod 16 (such as Figure 1 shown);
[0055] During this process, the suction pipe 12 facing the oil-absorbing paper will follow the rotation of the hollow rod 18 and move away from the notch 22. At this time, the suction pipe 12 faces the arc groove 21, and then the suction pipe 20 and the suction pipe 12 can be used to evacuate the cavity 9 facing the suction pipe 12, and the oil-absorbing paper in the adsorption groove 8 can be adsorbed and fixed, so that the oil-absorbing paper will not fall off.
[0056] Then, the electric push rod 16 is adjusted to extend, and the adsorption plate 6 can be pressed downward through the top outlet 11, driving the oil-absorbing paper in the adsorption tank 8 to move downward, so that the oil-absorbing paper contacts the skin, and the automatic sampling is completed without the need for manual operation by the staff, so as to avoid the adhesion of other substances on the oil-absorbing paper and affect the subsequent test results. When the electric push rod 16 extends, the driving motor 39 rotates clockwise, so that the two rifle rods 26 move up and down while rotating;
[0057] After sampling, the motor 39 stops, the electric push rod 16 is adjusted to return to the original position, and then the motor 39 is driven to rotate counterclockwise again, driving the ring 3 to rotate 90 degrees again, so that the oil-absorbing paper after sampling rotates to face the upper turntable 29;
[0058] Then the driving motor 39 rotates clockwise, at which time the inner ring of the second one-way bearing 41 drives its outer ring to rotate, and then drives the second rod 33 to rotate through the first wheel 44, the synchronous belt and the second wheel 45, and drives the first wedge plate 34 to rotate. At this time, the first wedge plate 34 will intermittently squeeze the two second wedge plates 35, thereby intermittently squeezing the two squeezing plates 27. At this time, the two squeezing plates 27 move up and down under the squeezing of the first wedge plate 34 and the action of multiple second springs 28. Under the action of the two threaded cylinders 25, the two rifle rods 26 are made to move up and down while rotating. When the rifle rod 26 located at the top is moved up and down while rotating, the turntable 29 and the multiple squeezing beads 30 are continuously rolled on the oil-absorbing paper, so that the grease on the oil-absorbing paper is evenly distributed, the contact area between the grease and the oil-absorbing paper is increased, and its detection effect is increased;
[0059] When the rifle rod 26 at the bottom rotates and moves up and down, the rotating disk 29 and the plurality of squeeze beads 30 continuously roll on the cleaning cotton 32, so as to clean the grease on the rotating disk 29 and the plurality of squeeze beads 30;
[0060] At the same time, after the motor 39 rotates counterclockwise to make the ring 3 rotate clockwise by 90 degrees, the third rod 36 drives the first rod 23 to rotate half a circle through the first bevel gear 37 and the second bevel gear 38, and the positions of the two rotating disks 29 are automatically changed to avoid contamination and improve the accuracy of subsequent detection results;
[0061] After the grease on the oil-absorbing paper is squeezed and evenly distributed, the motor 39 is driven to rotate counterclockwise again, and the ring 3 rotates clockwise by 90 degrees again. At this time, the rotating shaft 4 drives the fixed frame 5 to rotate half a circle under the action of the bevel gear 14 and the arc-shaped bevel gear plate 13, so that the oil-absorbing paper is located at the top and then moves to the bottom of the detector 17, and then the skin grease can be detected by the detector 17;
[0062] After the detection, the motor 39 is driven counterclockwise again to make the ring 3 rotate ninety degrees clockwise again. At this time, the vacuum pipe 12 corresponding to the oil-absorbing paper will move from the arc groove 21 to the groove 22. At this time, the air pressure in the cavity 9 is consistent with the external air pressure through the vacuum pipe 12 and the groove 22, which makes it convenient for the staff to take and put the oil-absorbing paper in the adsorption groove 8 corresponding to the cavity 9.
[0063] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
