DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0021] For example 1, please refer to Figure 1-Figure 5 , a sampling device for food safety detection based on an intelligent sensing system, comprising: The sampling chamber 100 is equipped with a disc cutter 200 driven by an electric telescopic rod and a sampling head 300 with an intelligent sensor; The conveying mechanism 400 is assembled at the bottom of the sampling chamber 100. The disc cutter 200 driven by the electric telescopic rod and the sampling head 300 with an intelligent sensor are activated to perform corresponding cutting operations on the food to be tested delivered by the conveying mechanism 400, and to sample the food to be tested after the cutting operation is completed, and the sample of the food to be tested is transferred to the sampling head 300; A reciprocating screw 501 is rotatably connected to the interior of the sampling chamber 100. A sliding seat 502 is threadedly connected to the exterior of the reciprocating screw 501. The sliding seat 502 is located within the sampling chamber 100 and is slidably connected to the chamber 100. A rotating rod 503 is rotatably connected to the side of the sliding seat 502. After completing a sampling operation, the sampling head 300 is first reset, and then the reciprocating screw 501, driven by the motor, is activated, causing the reciprocating screw 501 to rotate. The sliding seat 502, threadedly assembled on the reciprocating screw 501, is constrained by the sampling chamber 100 to which it is slidably connected, causing the sliding seat 502 to reciprocate on the reciprocating screw 501, driving the rotating rod 503, which is rotatably connected to the side of the sliding seat 502, to reciprocate with it.

[0022] A cleaning brush 504 is fixedly connected to the outside of the rotating rod 503, and a transmission member for transmission is installed between the sliding seat 502 and the cleaning brush 504. The transmission member includes a magnetic block 505 installed on the side of the sliding seat 502. A gear 506 is fixedly connected to the top of the rotating rod 503, and a fixed rod 507 is fixedly connected to the inside of the sampling chamber 100. The side of the fixed rod 507 is connected to teeth 509 by setting a torsion spring block 508. An iron block 510 is installed inside the cleaning brush 504, and a placement groove for placing the iron block 510 is opened inside the cleaning brush 504 and the rotating rod 503. When the rotating rod 503 moves back and forth, it drives the cleaning brush 504 fixedly connected to the rotating rod 503 to clean the disc cutter 200 and sweep away the residue attached to the disc cutter 200; when the rotating rod 503 and the cleaning brush 504 move close to the sampling chamber 100, the gear 506 fixedly connected to the rotating rod 503 moves to the fixed rod 507 and starts to mesh with it through the teeth 509 on the fixed rod 507, so that the gear 506 is restricted by the teeth 509 during the movement, and the teeth 509 are restricted by the fixed rod 507 at this time and will not rotate around the torsion spring block 508 as the axis, so as to prevent the gear 506 from rotating. Figure 4As shown in , when the gear 506 moves, it rotates 180 degrees counterclockwise, rotating the cleaning brush 504 that was originally away from the disc cutter 200 to the side close to the disc cutter 200, and the interior of the cleaning brush 504 is equipped with an iron block 510, and the side of the sliding seat 502 is equipped with a magnetic block 505. The magnetic block 505 can limit the cleaning brush 504 to the state after the rotation is completed by adsorbing the iron block 510. When the sliding seat 502 is reset, the gear 506 squeezes the teeth 509 from the other side. At this time, the teeth 509 can be rotated with the torsion spring block 508 as the axis, so that the teeth 509 do not limit the gear 506. In this way, the two sides of the cleaning brush 504 can clean the disc cutter 200 in turn, thereby improving the cleaning effect of the device on the disc cutter 200, thereby reducing the possibility of contamination when the device is sampled next time.

[0023] When in use, the disc cutter 200 driven by the electric telescopic rod and the sampling head 300 with the intelligent sensor are activated to perform the corresponding cutting operation on the food to be tested sent by the conveying mechanism 400, and the food to be tested after the cutting operation is completed is sampled and the food to be tested is sampled into the sampling head 300; after completing a sampling operation, the sampling head 300 is first reset, and then the reciprocating screw rod 501 driven by the motor is activated, so that the reciprocating screw rod 501 is in a rotating state, and the sliding seat 502 assembled on the reciprocating screw rod 501 by a thread is restricted by the sampling chamber 100 slidably connected thereto, so that the sliding seat 502 reciprocates on the reciprocating screw rod 501, driving the rotating shaft 100 to rotate. The rotating rod 503 connected to the side of the sliding seat 502 moves back and forth therewith, and the cleaning brush 504 fixedly connected to the rotating rod 503 can clean the disc cutter 200 and sweep away the residue attached to the disc cutter 200; when the rotating rod 503 and the cleaning brush 504 move close to the sampling chamber 100, the gear 506 fixedly connected to the rotating rod 503 moves to the fixed rod 507 and starts to mesh with it through the teeth 509 on the fixed rod 507, so that the gear 506 is restricted by the teeth 509 during the movement, and the teeth 509 are restricted by the fixed rod 507 at this time and will not rotate around the torsion spring block 508 as the axis, so as to prevent the gear 506 from rotating. Figure 4As shown in , when the gear 506 moves, it rotates 180 degrees counterclockwise, rotating the cleaning brush 504 that was originally away from the disc cutter 200 to the side close to the disc cutter 200, and the interior of the cleaning brush 504 is equipped with an iron block 510, and the side of the sliding seat 502 is equipped with a magnetic block 505. The magnetic block 505 can limit the cleaning brush 504 to the state after the rotation is completed by adsorbing the iron block 510. When the sliding seat 502 is reset, the gear 506 squeezes the teeth 509 from the other side. At this time, the teeth 509 can be rotated with the torsion spring block 508 as the axis, so that the teeth 509 do not limit the gear 506. In this way, the disc cutter 200 can be cleaned on both sides of the cleaning brush 504 in turn.

[0024] For example 2, please refer to Figure 1-Figure 7 On the basis of Example 1, the interior of the sampling chamber 100 is equipped with a cleaning assembly 600 for cleaning the sampling head 300. The cleaning assembly 600 includes a delivery pipe 601 assembled on the top of the sampling chamber 100 and connected to a liquid pump. A cam 602 is fixedly connected to the outer side of the reciprocating screw 501. A hydraulic chamber 1 603 is assembled on the top of the sampling chamber 100. One end of the hydraulic chamber 1 603 is slidably connected to a force-bearing rod 1 604 via a piston, and the other end of the hydraulic chamber 1 603 is slidably connected to an arc rod 1 605 via a piston. The liquid pump and the electric telescopic rod are activated to drive the cleaning liquid into the delivery pipe 601. When the reciprocating screw 501 rotates, the cam 602 assembled on the outside of the reciprocating screw 501 can be driven to rotate. When the protruding part of the cam 602 rotates to the force-bearing rod 1 604, the force-bearing rod 1 604 is squeezed and moves upward, pushing the oil originally stored in the hydraulic tank 1 603, so that the oil moves to the arc rod 1 605, driving the arc rod 1 605 to move.

[0025] The top of the force-bearing rod 604 is equipped with a spring 606, and the end of the spring 606 is away from the force-bearing rod 604 and is assembled on the inner wall of the hydraulic chamber 603. The interior of the delivery pipe 601 is rotatably connected to a penetrating transmission rod 607, and the outer side of the transmission rod 607 is fixedly connected to a force plate 608. The force plate 608 is located at the side of the arc rod 605 and is fixed to the arc rod 605. The bottom of the transmission rod 607 is fixedly connected to a block 609. The side of the delivery pipe 601 is equipped with a delivery hose 610. The interior of the sampling chamber 100 is equipped with a mobile pipe 611 driven by an electric telescopic rod, and the side of the mobile pipe 611 is equipped with a surrounding nozzle 612. When the arc rod 1 605 moves, it drives the force-bearing plate 608 fixedly connected thereto to rotate, so that the force-bearing plate 608 drives the transmission rod 607 fixedly connected thereto to rotate, and the transmission rod 607 drives the blocking block 609 fixedly connected thereto to rotate, thereby converting the originally closed delivery pipe 601 into an open state. The cleaning liquid randomly flows into the delivery hose 610 through the delivery pipe 601, and as the electric telescopic rod is activated, the mobile pipe 611 and the surrounding nozzle 612 move to the sampling head 30 where the reset is completed. 0, the cleaning liquid input through the delivery hose 610 is sprayed onto the outer surface of the sampling head 300 through the surrounding nozzle 612. When the protruding portion of the cam 602 continues to rotate and moves away from the force-bearing rod 1 604, the force-bearing rod 1 604 can be reset under the action of the spring 1 606. Similarly, the blocking block 609 is reset. In this way, the outer surface of the sampling head 300 can be intermittently cleaned, preventing the device from being contaminated by residues from the previous operation when sampling food, while reducing the waste of cleaning liquid.

[0026] When in use, based on the first embodiment, the liquid pump and the electric telescopic rod are activated to drive the cleaning liquid into the delivery pipe 601, and when the reciprocating screw 501 rotates, the cam 602 assembled on the outside of the reciprocating screw 501 can be driven to rotate. When the protruding part of the cam 602 rotates to the force-bearing rod 1 604, the force-bearing rod 1 604 is squeezed and moves upward, pushing the oil originally stored in the hydraulic tank 1 603, so that the oil moves to the arc rod 1 605, driving the arc rod 1 605 to move, and the arc rod 1 605 drives the force plate 608 fixedly connected to it to rotate, so that the force plate 608 drives the transmission rod 607 fixedly connected to it to rotate, and the transmission rod 607 drives the oil originally stored in the hydraulic tank 1 603 to move. The fixedly connected blocking block 609 rotates to convert the originally closed delivery pipe 601 into an open state, and the cleaning liquid randomly flows into the delivery hose 610 through the delivery pipe 601. As the electric telescopic rod is activated, the mobile pipe 611 and the surrounding nozzle 612 move to the sampling head 300 that has completed the reset, and the cleaning liquid input through the delivery hose 610 is sprayed onto the outer surface of the sampling head 300 through the surrounding nozzle 612. When the protruding part of the cam 602 continues to rotate and moves away from the force-bearing rod 1 604, the force-bearing rod 1 604 can be reset under the action of the spring 1 606. Similarly, the blocking block 609 is reset. In this way, the outer surface of the sampling head 300 can be intermittently cleaned.

[0027] For example three, please refer to Figures 1-8 In addition to the first and second embodiments, the sampling chamber 100 is equipped with an auxiliary cleaning assembly 700 for improving cleaning efficiency. The auxiliary cleaning assembly 700 includes a second hydraulic chamber 701 mounted on the side surrounding the nozzle 612. A hydraulic hose 702 is mounted on the top of the second hydraulic chamber 701. When the oil in the first hydraulic chamber 603 moves toward the first curved rod 605, some of the oil flows into the hydraulic hose 702, causing the oil originally stored in the hydraulic hose 702 to flow into the second hydraulic chamber 701.

[0028] The side of the hydraulic chamber 701 is slidably connected to the curved rod 703 via a piston. The end of the hydraulic hose 702, away from the hydraulic chamber 701, is mounted on the side of the curved rod 703. A rotating shaft 704 is connected to the side of the surrounding nozzle 612. A protective plate 705 is fixedly connected to the outside of the rotating shaft 704. The protective plate 705 is located on the side of the curved rod 703 and is fixed to the curved rod 703. When oil flows into the hydraulic chamber 701, the oil in the hydraulic chamber 701 flows toward the side closer to the curved rod 703, driving the curved rod 703, which is slidably connected to the hydraulic chamber 701 via the piston, to move. The curved rod 703 causes the protective plates 705, which are fixedly connected to it, to rotate. The protective plates 705 on both sides rotate, blocking the gap between the two surrounding nozzles 612, preventing the cleaning liquid from leaking out from the sides, further improving the cleaning effect of the device on the sampling head 300.

[0029] During use, based on Example 1 and Example 2, when the oil in the hydraulic tank 1 603 moves toward the arc rod 1 605, part of the oil flows into the hydraulic hose 702, so that the oil originally stored in the hydraulic hose 702 flows into the hydraulic tank 2 701, and the oil in the hydraulic tank 2 701 flows toward the side close to the arc rod 2 703, driving the arc rod 2 703 that is slidably connected to the hydraulic tank 2 701 by the piston to move, so that the arc rod 2 703 drives the protective plate 705 fixed to it to rotate, and the protective plates 705 on both sides rotate to block the gap between the two surrounding nozzles 612.

[0030] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
