Description

Technical Field

[0001] The present invention relates to the technical field of food detection, and specifically relates to a food detection sampling device and a using method thereof. Background Art

[0002] Food detection is based on some basic theories of physics, chemistry, and biology and various technologies, and in accordance with the formulated technical standards, such as international and national food hygiene standards, the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products is inspected to ensure that the product quality is qualified. The content of food inspection includes the sensory detection of food, the detection of nutrients, additives, and harmful substances in food, etc.;

[0003] Generally, when sampling and detecting liquid foods containing particles, the sampling tube is basically inserted into the liquid to suck the liquid to achieve the purpose of sampling. Generally, in order to prevent the entry of particles when the existing device sucks the liquid containing particles, a filter net is basically installed in the suction head to block. Since the liquid containing particles will be sucked during suction, when the filter net blocks the particles, it is easy to cause the suction head to be blocked, and during subsequent extraction, some particles will also enter synchronously with the flow of the liquid, resulting in particle breakage, which affects the sample quality and also affects the accuracy of subsequent detection.

[0018] Furthermore, a using method of a food detection sampling device, the food detection sampling device, the method includes the following steps:

[0019] S1: Sliding insertion: First, insert this device into the food bottle of the sampled food.

[0020] S2: Starting to rise: Then start the electric push rod. When the electric push rod starts, it will drive the piston rod to slide upward inside the main body.

[0021] S3: Rising and extracting: When the piston rod slides, it will extract the required liquid through the main body to complete the purpose of sampling the food liquid.

[0022] The present invention has the following beneficial effects:

[0023] 1. In the present invention, when the electric push rod drives the piston rod to slide upward inside the main body, the sliding of the piston rod will squeeze the gas between the electric push rod and the inner wall of the top of the main body. When the gas is squeezed by the sliding of the piston rod, it will enter the inside of the piston tube through a plurality of connecting pipes respectively. When the gas enters the inside of the piston tube, it will squeeze the push rod inside the piston tube. When the push rods inside the plurality of piston tubes slide downward, they will drive the sliding ring to slide downward synchronously. At the same time, when the piston rod sucks the liquid, the flow of the liquid entering the main body will impact the spiral cylinder and the fan inside the spiral cylinder and drive the second rotating ring to rotate. When the second rotating ring rotates, it will drive the rotating ring to rotate through the second rotating plate and the first rotating plate. At the same time, when the sliding ring slides downward, several first rotating plates at the bottom of the sliding ring will expand outward under the push of the second rotating plate. When the first rotating plate expands outward, it will twist the spring on the first rotating plate and push the bending rod and the middle plate to expand synchronously. Subsequently, when the spiral cylinder rotates, it will drive the expanded bending rod through the second rotating plate to rotate inside the liquid while expanding. When the bending rod rotates, it will drive the middle plate to rotate synchronously inside the liquid. When the plurality of middle plates and bending rods rotate, vortices will be generated in the liquid. The centrifugal force generated when the vortices rotate with the middle plate will disperse the impurity particles in the liquid to the surroundings, avoiding the aggregation of impurities near the center of the bottom of the main body, reducing the situation of impurities entering during the liquid suction and blockage caused by the aggregation of impurity particles during the liquid suction by the main body, thereby ensuring the continuity and stability of the sampling process and improving the sampling efficiency.

[0024] 2. In the present invention, when the piston rod slides upward, the springs on several spring rods at the bottom of the chassis are no longer compressed and push the chassis to drive the top cover to slide upward. When the chassis slides upward, it will drive the first conical plate to rotate through the movable plate and the auxiliary plate connected thereto. When multiple first conical plates rotate, a conical channel will be formed inside the inner cylinder. At the same time, when the first conical plates rotate, they will drive the cross plate to rotate. Also, when the piston rod slides upward to extract the liquid, the entry of the liquid will drive multiple flexible belts to flip upward and fit against the side walls of the first conical plates. The ends of the flexible belts will contact the side walls of the cross plate, as shown in the figure. Subsequently, when the liquid flow drives the spiral cylinder to rotate, the rotation of the spiral cylinder will drive the spherical chain to rotate synchronously. When the spherical chain rotates, it will disturb the liquid flowing in the conical channel. When the liquid in the conical channel is disturbed by the spherical chain, it will drive the cross plate to slide back and forth through the ends of the flexible belts. When the cross plate slides, it will repeatedly slap the flowing liquid through the ends of the flexible belts. Combining the agitation of the liquid by the spherical chain, it will continuously impact and disturb the liquid surface, which can break the surface tension balance of the liquid and thus reduce the situation where bubbles enter the main body due to the excessive rotation of the middle plate and the too-fast extraction speed of the liquid during extraction, and reduce the impact of the entry of bubbles on the accuracy of subsequent detection, improving the detection efficiency of subsequent detection and analysis.

[0025] 3. In the present invention, when the ends of multiple flexible belts drive the cross plate to slide back and forth under the agitation of the liquid, it will push the top cover to slide up and down through the second push rod. When the top cover slides up and down, it will drive the fixed ring to slide synchronously. When the fixed ring slides upward, it will drive the second conical plate to rotate at the bottom of the chassis through multiple connecting springs. When multiple second conical plates rotate, a conical cylinder will be formed on the surface of the flexible sleeve. When multiple second conical plates rotate to form a conical cylinder, it will push the flexible sleeve to form a conical channel. When the liquid passes through the circular groove on the chassis and through the conical channel formed by the flexible sleeve, the flow rate of the liquid will be accelerated. Subsequently, when the top cover slides downward, it will drive the second conical plate forming the conical cylinder to separate through the connecting springs. Under such reciprocation of the top cover, the conical cylinder formed by multiple second conical plates will be reciprocally closed and separated. At the same time, the periodic change of the conical channel will generate a local pressure difference in the liquid. When multiple second conical plates are closed to form the conical channel, the flow rate of the liquid in the channel increases and the pressure decreases, while when multiple second conical plates open, the pressure in the channel relatively increases. This change in pressure difference can drive the liquid to flow faster, thereby increasing the extraction speed of the liquid and reducing the situation where the resistance of the liquid increases during the suction and flow due to the disturbance of the liquid by the flexible chain and the ends of the flexible belts, resulting in a decrease in the liquid extraction speed and affecting the sampling efficiency.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] A usage method of a food detection sampling device, a food detection sampling device, the method comprising the following steps:

[0053] S1: Sliding insertion: First, insert this device into the food bottle of the sampled food.

[0054] S2: Starting to rise: Subsequently, start the electric push rod 101. When the electric push rod 101 starts, it will drive the piston rod 102 to slide upward inside the main body 1.

[0055] S3: Rising extraction: When the piston rod 102 slides, it will extract the required liquid through the main body 1 to complete the purpose of sampling the food liquid.

[0056] When in use, first insert this device into the food bottle of the sampled food. Subsequently, start the electric push rod 101. When the electric push rod 101 starts, it will drive the piston rod 102 to slide upward inside the main body 1. When the piston rod 102 slides, it will extract the required liquid through the main body 1 to complete the purpose of sampling the food liquid.

[0057] When the electric push rod 101 drives the piston rod 102 to slide upward inside the main body 1, the sliding of the piston rod 102 will squeeze the gas between the electric push rod 101 and the inner wall of the top of the main body 1.

When the push rods 203 inside the plurality of piston tubes 202 slide downward, they will drive the sliding ring 204 to slide downward synchronously. At the same time, when the piston rod 102 extracts the liquid, the flow of the liquid when it enters the main body 1 will impact the spiral cylinder 306 and the fan inside the spiral cylinder 306 and drive the second rotating ring 305 to rotate. When the second rotating ring 305 rotates, it will drive the rotating ring 205 to rotate through the second rotating plate 304 and the first rotating plate 301. At the same time, when the sliding ring 204 slides downward, a plurality of first rotating plates 301 at the bottom of the sliding ring 204 will expand outward under the push of the second rotating plate 304. When the first rotating plate 301 expands outward, it will twist the spring on the first rotating plate 301 and push the bending rod 303 and the middle plate 302 to expand synchronously. Subsequently, when the spiral cylinder 306 rotates, it will drive the expanded bending rod 303 through the second rotating plate 304 to rotate inside the liquid while expanding. When the bending rod 303 rotates, it will drive the middle plate 302 to rotate synchronously inside the liquid. When a plurality of middle plates 302 and bending rods 303 rotate, vortices will be generated in the liquid. The centrifugal force generated when the vortices rotate with the middle plate 302 will disperse the impurity particles in the liquid to the surroundings, preventing impurities from accumulating near the center of the bottom of the main body 1, reducing the situation of impurities entering during liquid extraction and blockage due to the accumulation of impurity particles when the main body 1 extracts the liquid, thereby ensuring the continuity and stability of the sampling process and improving the sampling efficiency.

[0058] When the piston rod 102 slides upward, the springs on a plurality of spring rods at the bottom of the chassis 601 will no longer be compressed and push the chassis 601 to drive the top cover 602 to slide upward. When the chassis 601 slides upward, it will drive the first conical plate 403 to rotate through the movable plate 405 and the auxiliary plate connected thereto. When a plurality of first conical plates 403 rotate, a conical channel will be formed inside the inner cylinder 401. At the same time, when the first conical plate 403 rotates, it will drive the cross plate 502 to rotate. At the same time, when the piston rod 102 slides upward to extract the liquid, the entry of the liquid will drive a plurality of flexible belts 404 to flip upward and fit against the side wall of the first conical plate 403. The end of the flexible belt 404 will contact the side wall of the cross plate 502, as Figure 6As shown in [figure], when the spiral cylinder 306 rotates driven by the flow of the liquid, the rotation of the spiral cylinder 306 will drive the spherical chain to rotate synchronously. When the spherical chain rotates, it will disturb the liquid flowing in the conical channel. When the liquid in the conical channel is disturbed by the spherical chain, it will drive the cross plate 502 to slide back and forth through the end of the flexible belt 404. When the cross plate 502 slides, it will reciprocally beat the flowing liquid through the end of the flexible belt 404. Combining the agitation of the spherical chain on the liquid, it will continuously impact and disturb the liquid surface, which can break the surface tension balance of the liquid and thus reduce the situation that air bubbles enter the main body 1 due to the too fast rotation of the extraction intermediate plate 302 and the too fast extraction speed of the liquid, reducing the impact of the entry of air bubbles on the accuracy of subsequent detection and improving the detection efficiency of subsequent detection and analysis.

[0059] When the ends of multiple flexible belts 404 are driven by the agitation of the liquid to drive the cross plate 502 to slide back and forth, it will push the top cover 602 to slide up and down through the push rod two 603. When the top cover 602 slides up and down, it will drive the fixed ring 701 to slide synchronously. When the fixed ring 701 slides upward, it will drive the second conical plate 703 to rotate at the bottom of the chassis 601 through multiple connecting springs 702. When multiple second conical plates 703 rotate, a conical cylinder will be formed on the surface of the flexible sleeve 604. When multiple second conical plates 703 rotate to form a conical cylinder, it will push the flexible sleeve 604 to form a conical channel. When the liquid passes through the circular groove on the chassis 601 and passes through the conical channel formed by the flexible sleeve 604, the flow of the liquid will be accelerated. Subsequently, when the top cover 602 slides downward, it will drive the second conical plate 703 forming the conical cylinder to separate through the connecting spring 702. Under the reciprocation of the top cover 602 like this, the conical cylinder formed by multiple second conical plates 703 will be reciprocally closed and separated. At the same time, the periodic change of the conical channel will generate a local pressure difference in the liquid. When multiple second conical plates 703 are closed to form a conical channel, the flow rate of the liquid in the channel increases and the pressure decreases, while when multiple second conical plates 703 open, the pressure in the channel relatively increases. This change in pressure difference can push the liquid to flow faster, thereby increasing the extraction speed of the liquid and reducing the situation that the resistance of the liquid increases during the suction and flow of the liquid due to the disturbance of the flexible chain and the ends of the flexible belt 404, resulting in a decrease in the liquid extraction speed and affecting the sampling efficiency.
