Description

Technical Field

[0001] The invention relates to the technical field of food safety detection, in particular to an intelligent cheese detection device. Background Art

[0002] Cheese, also known as cottage cheese, is a fermented milk product. Its properties are similar to common yogurt. Both are made through a fermentation process and contain lactic acid bacteria that can be used for health. However, the concentration of cheese is higher than that of yogurt, and it is close to solid food, so its nutritional value is richer.

[0003] For example, a patent with publication number CN219915259U and publication date October 27, 2023 discloses a water activity detector for cheese production, which relates to the technical field of preparation of cheese for testing, and includes a detection box, one side end of the detection box is movably connected with a box door, an observation window is provided in the center of the box door, a handle is provided on one end of the box door, a controller is provided on the top of the detection box, a display screen is provided on one end of the controller, a weighing machine is provided at the inner bottom of the detection box, a heating plate is provided on the top of the weighing machine, a placing table is provided on the top of the heating plate, solid cheese is placed on the placing table by a limiting device, and a detection device is provided at the inner top of the detection box above the solid cheese.

[0004] Existing cheese detection includes moisture detection, odor detection, shape detection, etc. When performing odor detection on cheese, the cheese is usually placed on a can or other object, and then the odor emitted by the cheese is transported to the odor detection mechanism to achieve odor detection of the cheese, that is, to judge whether the cheese has deteriorated by the odor. However, among the existing cheese products, some cheese products contain a filling inside, such as the cheese sticks that are popular on the market. When performing odor detection on this part of the cheese, the filling inside should also be the object to be detected. Since in most cases the corruption starts from the outside, it is assumed in the prior art that external corruption precedes internal corruption. Since the filling is wrapped inside the cheese product, the odor cannot be emitted to the outside, and it cannot be sent to the odor detection mechanism. In other words, whether the filling part is deteriorated cannot be detected by the odor detection mechanism, resulting in inaccurate detection results. The detection of the cheese part alone cannot represent the overall detection of the cheese product, nor can it be judged whether the cheese product is deteriorated. In fact, in many cases, the material of the filling part is more susceptible to corruption, such as the wine filling product, and it cannot be guaranteed that the corruption of the cheese product starts from the outside.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] In the description of the present invention, unless otherwise specified, "multiple" means two or more than two; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figure 1-5 As shown, an embodiment of the present invention provides an intelligent cheese detection device, including a detection table 1, on which a sampling mechanism 2 and an odor detection mechanism 3 are installed, the sampling mechanism 2 is connected to the odor detection mechanism 3, and the cheese product to be tested is placed on the detection table 1, and the sampling mechanism 2 can be lowered and inserted into the cheese product to be tested to achieve sampling of the inside of the cheese product.

[0028] Specifically, the upper surface of the testing table 1 is horizontal, the cheese product to be tested is located on the upper surface of the testing table 1, and the sampling mechanism 2 is located above the cheese to be tested. The sampling mechanism 2 can be a tubular structure such as a glass tube, which is driven to descend and inserted into the cheese product to be tested. The odor detection mechanism 3 can be a gas sensor arranged in a container. The gas sensor is a prior art and is not described here. The container is connected to the glass tube through a pipeline. In actual use, the glass tube descends under the drive of a driving member, which is a cylinder 23. The glass tube descends and is inserted into the cheese product below. At this time, part of the cheese product enters the glass tube. The sample that enters includes the cheese part and the sandwich part. At this time, the sandwich part is exposed in the glass tube. Subsequently, the odor emitted by the cheese and the sandwich enters the pipeline through the holes on the side of the glass tube, and enters the odor detection mechanism 3 through the pipeline. A fan or other exhaust mechanism is arranged in the pipeline for conveying gas. The odor of the surface part and the sandwich part of the cheese product is detected by the odor detection mechanism 3 to determine whether the cheese part or the sandwich part is deteriorated, thereby realizing the detection of the complete cheese product.

[0029] It should be noted that a backwash nozzle (not shown) can be provided inside the glass tube to clean the residue in the glass tube by using backwash technology. In an ideal way, after the sample is tested, the residue in the glass tube can be wiped off by manual wiping to prevent the residue from affecting the subsequent cheese product testing.

[0030] In an optional embodiment, preferably, the sampling mechanism 2 includes an inner tube 21 and an outer tube 22 , the inner tube 21 is sleeved inside the outer tube 22 and slidably connected to the outer tube 22 , and the inner tube 21 is driven to rise and fall inside the outer tube 22 .

[0031] Specifically, the inner tube 21 and the outer tube 22 are both arranged vertically, the bottom of the outer tube 22 is provided with an opening, and one side of the opening is provided with an electric switch door, which is used to seal the bottom opening of the outer tube 22. This is a prior art and will not be repeated. The upper end of the outer tube 22 is a closed structure, that is, only the lower end is provided with an opening. A support plate 11 is fixedly installed above the detection platform 1, and the support plate 11 is arranged horizontally. The inner tube 21 is installed between the support plate 11 and the detection platform 1, and the upper end of the inner tube 21 is fixedly connected to the lower plate surface of the support plate 11. The upper plate surface of the support plate 11 is fixedly connected to the cylinder 23. The telescopic shaft at the output end of the cylinder 23 passes through the support plate 11 and the outer tube 22 and extends into the interior of the outer tube 22, and the end extending into the outer tube 22 is connected to the upper end of the inner tube 21. The cylinder 23 drives the inner tube 21 to rise and fall in the outer tube 22. In the initial state, the inner tube 21 The cylinder 23 is contracted inside the outer tube 22. When testing the cheese product, the cylinder 23 drives the inner tube 21 to descend and extend from the bottom of the outer tube 22. The extended inner tube 21 is inserted into the cheese product. The upper cheese part, the middle sandwich part and the lower cheese part of the cheese product, i.e., three parts of the sample, are extracted by the descent of the inner tube 21 to form a sample to be tested. Then the cylinder 23 drives the inner tube 21 to return to its original position, rise and shrink inside the outer tube 22. Since the inner tube 21 is directly inserted into the cheese product, the extracted sample will be tightly attached to the inner wall of the inner tube 21, and the cheese has a certain hardness. Therefore, when the inner tube 21 rises, the sample in the inner tube 21 will not fall out or the probability of falling out is very low. After the sample is sampled, the smell of the sample is emitted in the inner tube 21 and transported to the odor detection mechanism 3 through the pipeline.

[0032] In an optional embodiment, preferably, the inner tube 21 is composed of a plurality of groups of arc-shaped plates 211 , and the plurality of groups of arc-shaped plates 211 can be separated radially.

[0033] Specifically, during the sample extraction process of the inner tube 21, the extracted sample still includes the upper cheese portion, the middle sandwich portion and the lower cheese portion, and the three portions are still tightly attached to the inner tube 21, and the sandwich portion is still located between the upper cheese portion and the lower cheese portion. Although there is a certain gap between the two cheese portions and the inner wall of the inner tube 21, a small gap is not conducive to the odor emission of the middle sandwich portion. Therefore, in this embodiment, the inner tube 21 is composed of a plurality of groups of arc plates 211. The plurality of groups of arc plates 21 1 can be separated radially. After the inner tube collects the sample, the multiple groups of arc plates 211 move radially, that is, the multiple groups of arc plates 211 separate radially, and the gaps between adjacent arc plates 211 are opened, and the cylindrical structure of the inner tube 21 disappears. By opening the gap, the cavity in the initial inner tube 21 is connected with the cavity in the outer tube 22, and the collected sample can be emitted into the outer tube 22. The odor emitted from the outer tube 22 is transported to the odor detection mechanism 3 through the pipeline for detection; after the sample is detected, the inner tube 21 needs to be sampled again. When collecting, the multiple groups of arc plates 211 are radially reset and moved and spliced ​​together into a cylindrical structure, which is the inner tube 21. The spliced ​​inner tube 21 is inserted into the cheese product; when the inner tube 21 is extracted and reset and moved into the outer tube 22, the outer tube 22 closes the electric switch door at the bottom, that is, the bottom opening of the outer tube 22 is sealed. At this time, the lower end of the inner tube 21 contacts the electric switch door, and then the multiple groups of arc plates 211 formed in the inner tube 21 are radially separated, that is, the gaps between adjacent arc plates 211 are opened. , so that the cavity in the inner tube 21 and the cavity in the outer tube 22 are interconnected, that is, the collected sample is exposed to the cavity inside the outer tube 22, and the inner tube 21 is lost. The cavity of the outer tube 22 provides sufficient space support for the dissemination of the sample odor, avoiding the problem that the sample odor cannot be fully dissipated due to being close to the wall of the inner tube 21. The wall of the outer tube 22 is opened and closed with holes, and the holes are the holes on the outer wall of the glass tube in the above embodiment. Then the emitted odor enters the odor detection mechanism 3 through the holes and the pipeline.

[0034] In an optional embodiment, preferably, a separation mechanism 4 is installed at the upper end of the inner tube 21 , and the separation mechanism 4 connects the multiple groups of arc plates 211 and drives the multiple groups of arc plates 211 to separate radially.

[0035] Specifically, the separation mechanism 4 includes a fixed plate 41, which is a cylindrical structure with a hollow interior and a single opening at the bottom. The fixed plate 41 is installed at the upper end of the inner tube 21 and is located in the outer tube 22. A rotating disk 42 and a fixed disk 43 are arranged inside the fixed plate 41. The rotating disk 42 is located below the fixed disk 43 and is rotatably connected to the lower surface of the fixed disk 43. The fixed disk 43 is fixedly installed on the inner wall of the fixed plate 41. An inclined groove 421 is provided on the rotating disk 42, and a guide groove 431 is provided on the fixed disk 43. The guide groove 431 is provided along the radial direction of the fixed disk 43. In the vertical projection, the inclined groove 421 intersects with the guide groove 431. A sealing plate 44 is installed below the rotating disk 42, and the sealing plate 44 is located between the rotating disk 42 and the fixed disk 43. A slider 45 is installed on the upper surface of the sealing plate 44. The slider 45 sequentially penetrates the inclined groove 421 and the guide groove 431, wherein the slider 45 is located in the guide groove 431. The structure is rectangular, that is, the limiting slider 45 can only drive the sealing plate 44 to move along the groove direction of the guide groove 431, that is, to move radially, and cannot rotate. The part of the slider 45 located in the inclined groove 421 is cylindrical, that is, the slider 45 can rotate relative to the inclined groove 421 in the inclined groove 421. In other words, the rotation of the inclined groove 421 driven by the rotating disk 42 can force the slider 45 to move radially. Limiting rings are installed on both ends of the upper and lower ends of the slider 45. The diameter of the limiting ring is larger than the groove width of the guide groove 431 and the inclined groove 421, which can prevent the slider 45 from escaping and shaking from the inclined groove 421 and the guide groove 431. The upper surface of the fixed disk 43 is fixedly connected with a motor 46. The output shaft of the motor 46 passes through the fixed disk 43. The diameter of the fixed disk 43 is larger than the diameter of the rotating disk 42. The outer wall of the rotating disk 42 is provided with a tooth groove, and a gear 47 is provided on one side. The tooth groove meshes with the gear 47. One end of the output shaft of the motor 46 passes through the fixed disk 43 and is fixedly connected to the gear 47.

[0036] When multiple sets of arc-shaped plates 211 are combined to form the inner tube 21, the slider 45 is located at one end of the guide groove 431 and the inclined groove 421 close to the central axis of the fixed plate 43, and this end is recorded as the starting end;

[0037] When the multiple groups of arc-shaped plates 211 are separated from each other, the slider 45 is located at the end of the guide groove 431 and the inclined groove 421 away from the central axis of the fixed plate 43, and this end is recorded as the terminal end;

[0038] In actual use, the motor 46 drives the gear 47 on the output shaft to rotate, the gear 47 meshes with the tooth groove and drives the rotating disk 42 to rotate at the bottom of the fixed disk 43, and the rotation of the rotating disk 42 drives the slider 45 to slide on the guide groove 431. Due to the inclined setting of the guide groove 431, the slider 45 will move from the starting end to the end end. Since the fixed disk 43 is fixed inside the fixed plate 41, the fixed disk 43 remains stationary. Driven by the inclined groove 421, the slider 45 moves from the starting end to the end end of the guide groove 431. Since the guide groove 431 is opened along the radial direction of the fixed disk 43, the slider 45 moves from the starting end to the end end of the guide groove 431. Assume that the slider 45 moves radially and drives the arc plate 211 to move radially through the sealing plate 44, that is, moves to the side away from the central axis of the fixed disk 43, that is, multiple groups of sliders 45 drive multiple groups of arc plates 211 to move radially to achieve radial separation. As the multiple groups of arc plates 211 separate radially, the gaps between the multiple groups of arc plates 211 are opened, and the cavity in the inner tube 21 is connected with the cavity in the outer tube 22 until the slider 45 moves to the end end and the arc plate 211 stops moving, that is, at this time the arc plate 211 is located between the sample and the inner wall of the outer tube 22.

[0039] In another embodiment of the present invention, further, a sealing gasket 411 is installed on the outer wall of the fixing plate 41 , and a gas delivery mechanism 5 is installed and connected to one side of the sampling mechanism 2 .

[0040] Specifically, since the inner tube 21 needs to be reciprocated and lowered multiple times to collect different samples, the odor emitted by the sample will remain in the outer tube 22, thereby affecting the subsequent sample odor detection. Therefore, in order to reduce the odor remaining in the outer tube 22, in this embodiment, a piston pad is installed on the outer wall of the fixed plate 41. The fixed plate 41 is a disc-shaped structure. The fixed plate 41 contacts the inner wall of the outer tube 22 through the sealing pad 411, that is, the fixed plate 41 and the sealing pad 411 are combined to form a piston in the outer tube 22. The upper outer wall of the outer tube 22 is provided with a through hole, and the through hole is also connected to the gas delivery mechanism 5 through a pipeline. The gas delivery mechanism 5 can be a tank for storing gas. The gas stored in the tank is a gas without odor and bacteria, such as nitrogen and air after disinfection, that is, the standard gas required for detection. The gas does not interfere with the detection of the odor detection mechanism 3, that is, the gas does not affect the emission of odor and the detection result of odor;

[0041] The fixed plate 41 divides its cavity into a first chamber 221 and a second chamber 222 in the outer tube 22. The first chamber 221 is located below the fixed plate 41, and the second chamber 222 is located above the fixed plate 41. The odor detection mechanism 3 is connected to the first chamber 221, and the gas delivery mechanism 5 is connected to the second chamber 222, that is, the second chamber 222 stores standard gas, and the gas stored in the first chamber 221 contains the odor emitted by the sample. The descending stroke of the inner tube 21 is recorded as the first stroke, and the returning and ascending stroke of the inner tube 21 is recorded as the second stroke.

[0042] In the first stroke, initially, the inner tube 21 is located inside the outer tube 22, that is, when the smell of the sample is detected, the multiple groups of arc plates 211 constituting the inner tube 21 are radially separated, and the first chamber 221 and the second chamber 222 are initially in an open state. The smell is emitted in the first chamber 221 and enters the smell detection mechanism 3 for detection. After the sample has been detected, the separation mechanism 4 drives the multiple groups of arc plates 211 to reset and form the inner tube 21, and the electric switch door at the bottom of the outer tube 22 is opened. The detected sample falls from the bottom opening of the outer tube 22 and can be collected by an external collection device. At this time, the cylinder 23 drives the fixed plate 41 to descend in the inner tube 21. A second hole is opened on the fixed plate 41, and a second valve 412 is arranged in the second hole. When the fixed plate 41 descends, the second valve 412 is in a closed state. When the fixed plate 41 descends, it is driven by the sealing gasket 411 to gradually squeeze the first chamber 2 21, the space of the first chamber 221 is squeezed and shrunk, because a first hole is opened at the bottom of the outer tube 22, and a first valve 224 is installed in the first hole. The first valve 224 is a one-way valve, which is a prior art and will not be described in detail. The one-way valve only allows the first chamber 221 to discharge the inner body to the outside, and prohibits external air from entering the first chamber 221. Therefore, the gas in the first chamber 221 is pushed out from the inside of the outer tube 22 by the sealing plate 44, that is, the gas in the first chamber 221 is discharged from the first hole, and at the same time, the space of the second chamber 222 gradually increases with the descending of the fixed plate 41, and the gas delivery mechanism 5 also delivers the standard gas stored inside to the second chamber 222 until the fixed plate 41 descends to the bottom of the outer tube 22, and the inner tube 21 is inserted into the cheese product to be tested. The space of the first chamber 221 is completely squeezed and disappears by the fixed plate 41, and the gas containing odor therein is also discharged from the outer tube 22;

[0043] In the second stroke, that is, the inner tube 21 needs to be re-extended into the outer tube 22 after the sample is collected, the cylinder 23 drives the fixed plate 41 to rise, and the second valve 412 on the fixed plate 41 is opened at this time. The second valve 412 is an electrically controlled valve, which is a prior art and will not be described in detail. The second valve 412 drives the inner tube 21 to gradually rise and extend into the outer tube 22. Because the outer wall of the inner tube 21 dynamically seals the bottom opening of the outer tube 22, it is difficult for external air to enter the outer tube 22. Therefore, when the fixed plate 41 rises, the first chamber 221 is gradually formed. , the space of the second chamber 222 is reduced, and the opening of the second valve 412 allows the air in the second chamber 222 to enter the first chamber 221, that is, fresh air or standard air enters the first chamber 221, until the fixed plate 41 is reset to the initial position, the fixed plate 41 stops rising, and the first chamber 221 and the second chamber 222 are reset to their initial sizes. By inputting the air in the second chamber 222, it can be avoided that the residual odor in the first chamber 221 affects the subsequent odor detection effect of the cheese product, i.e., the sample.

[0044] In another embodiment of the present invention, further, an air outlet 441 is opened on the sealing plate 44, and the air outlet 441 is connected to the inner tube 21. A piston plate 48 is also installed in the outer tube 22. The piston plate 48 is located above the fixed plate 41. The piston plate 48 is connected to the fixed plate 41 through a telescopic member 49, and the air outlet 441 penetrates the fixed plate 41 through a pipe.

[0045] Specifically, the piston plate 48 is located in the second chamber 222, and the second chamber 222 is separated so that the inner tube 21 also includes a third chamber 223. The third chamber 223 is located between the fixed plate 41 and the piston plate 48, that is, between the first chamber 221 and the second chamber 222. The second chamber 222 is located above the piston plate 48. The telescopic member 49 in this embodiment is a telescopic tube, which is a prior art and will not be described in detail. The upper end of the telescopic tube is connected to the piston plate 48, and the lower end is connected to the fixed plate 41. The piston plate 48 is dynamically sealed and connected to the outer tube 22, and a third hole is opened inside. A third valve 481 is installed in the third hole. The third valve 481 is an electrically controlled valve. This is a prior art and will not be described in detail. The output shaft of the cylinder 23 is connected to the upper surface of the piston plate 48, that is, it is connected to the fixed plate 41 through the piston plate 48 and the telescopic member 49. The air outlet 441 on the sealing plate 44 is also connected to the third chamber 223 through a pipeline. The pipeline is a hose that adapts to the radial movement of the sealing plate 44.

[0046] In the first stroke, in the initial state, the telescopic tube is in a contracted state, and the space of the second chamber 222 is reduced to the minimum. At this time, the cylinder 23 drives the piston plate 48 to descend. Because the telescopic tube cannot be contracted, the fixed plate 41 is pushed down synchronously under the resistance of the telescopic tube, and the inner tube 21 is driven to descend synchronously, that is, the inner tube 21 extends from the bottom opening of the outer tube 22, and the space of the first chamber 221 is squeezed and reduced. At the end of the stroke, the first chamber 221 disappears, the second chamber 222 gradually expands, and the third chamber 223 remains in a contracted state;

[0047] In the second stroke, after the inner tube 21 collects the sample in the cheese product, the cylinder 23 drives the piston plate 48 to rise inside the outer tube 22. Because the piston plate 48 and the fixed plate 41 are both dynamically sealed and connected to the inner wall of the outer tube 22, that is, the piston plate 48 and the fixed plate 41 have a certain friction force on the inner wall of the outer tube 22, when the piston plate 48 rises, the telescopic tube will be stretched first, and the fixed plate 41 remains stationary, that is, the space of the third chamber 223 is gradually enlarged, the third valve 481 is opened, and the air in the second chamber 222 enters the third chamber 223 through the third hole. When the telescopic tube is stretched to the limit length, the piston plate 48 will pull the fixed plate 41 to rise synchronously through the telescopic tube. At this time, the inner tube 21 gradually rises and enters the outer tube 22. The space of the first chamber 221 is gradually enlarged, the space of the second chamber 222 continues to shrink, and the space of the third chamber 223 remains unchanged. The second valve 412 is opened, and the air in the second chamber 222 enters the first chamber 221 through the third chamber 223 and the second hole. When the inner tube 21 completely enters the outer tube 22, the outer tube 22 closes the bottom opening, and the inner tube 21 is The lower end surface abuts against the electric switch door at the bottom opening of the outer tube 22. After the multiple arc plates 211 constituting the inner tube 21 are separated from each other, the second valve 412 and the third valve 481 are closed, and the air in the third chamber 223 cannot directly enter the first chamber 221 and the second chamber 222. The cylinder 23 drives the piston plate 48 down again, the telescopic tube begins to contract, the space in the second chamber 222 begins to expand, and the space in the third chamber 223 begins to shrink. The space in the first chamber 221 remains unchanged, so the air in the third chamber 223 will pass through The hose is transported to the sealing plate 44 and discharged from the air outlet 441 of the sealing plate 44. Since the air outlet is located directly above the sample collected by the inner tube 21, the exhausted gas will blow toward the sample and drive the air flow in the first chamber 221, so that the odor emitted by the sample can be quickly diffused to the first chamber 221, and the first chamber 221 is connected to the odor detection mechanism 3. The injection of air in the third chamber 223 can also realize the delivery of air with the detection odor in the first chamber 221 to the odor detection mechanism 3, thereby facilitating the odor detection of the sample.

[0048] It should be noted that a one-way valve (not shown) is also installed at the connection between the gas delivery mechanism 5 and the second chamber 222. The one-way valve only allows the gas in the gas delivery mechanism 5 to be delivered to the second chamber 222, and prohibits the air in the second chamber 222 from flowing into the gas delivery mechanism 5. Therefore, in the second stroke, when the space in the second chamber 222 is reduced, the gas and air therein will not flow back into the gas delivery mechanism 5, but will be delivered to the third chamber 223.

[0049] In another embodiment of the present invention, further, a flow control mechanism is fixedly installed in the piston plate 48 .

[0050] Specifically, the flow control mechanism and the third valve 481 are both located in the third hole. The flow control mechanism is used to control the input amount of gas from the second chamber 222 to the third chamber 223. The flow control mechanism is the flow valve 482. In this embodiment, the telescopic member 49 is an electric push rod, which is located in the third chamber 223. The upper end of the electric push rod is connected to the piston plate 48, and the lower end is connected to the fixed plate 41.

[0051] In the second stroke, the electric push rod is initially in a retracted state, which is consistent with the state of the telescopic tube. After the inner tube 21 collects samples from the cheese product, the cylinder 23 drives the piston plate 48 to rise inside the outer tube 22. Under the pulling of the electric push rod, the fixed plate 41 rises synchronously with the piston plate 48, and in the rising process, the electric push rod gradually stretches and pushes the fixed plate 41 down. Because the stretching speed of the electric push rod is less than the contraction of the cylinder 23, that is, the descending speed of the fixed plate 41 is less than the rising speed pulled by the fixed plate 41, therefore, although the electric push rod is stretched, the fixed plate 41 still rises with the piston plate 48, but the rising speed of the fixed plate 41 is less than the rising speed of the piston plate 48, a speed difference is formed between the two, and the distance between the piston plate 48 and the fixed plate 41 is gradually enlarged. Therefore, in this process, the space in the first chamber 221 and the third chamber 223 is also gradually expanded, and the air in the second chamber 222 enters the third chamber 223 through the third hole. In the embodiment of the present invention, the air in the third chamber 223 will also enter the first chamber 221 through the second hole. At this time, the air entering the third chamber 223 from the second chamber 222 is controlled by the flow valve 482 arranged in the third hole, that is, the second chamber 222 injects a gas flow smaller than the gas flow required for the expansion of the third chamber 223 and the first chamber 221 into the gas flow in the third chamber 223. The third chamber 223 will generate suction due to the insufficient gas flow. Since the third chamber 223 is connected with the inner tube 21 through the pipeline and the air outlet 441, part of the suction generated will be transmitted to the inner tube 21. Secondly, the collected sample is located at the bottom opening of the inner tube 21, so the suction generated by the inner tube 21 can firmly adsorb the sample in the inner tube 21. That is to say, in the process of the inner tube 21 rising, a certain suction will be generated therein, which can reduce the possibility that the cheese part in the sample will soften due to deterioration or high temperature and fall off from the bottom of the inner tube 21.

[0052] It should be noted that a solenoid valve (not shown) is also installed at the connection between the first chamber 221 and the odor detection mechanism 3. The solenoid valve is only in an open state when the sample is statically arranged inside the outer tube 22, and is in a closed state at other time periods, so it is difficult for the third chamber 223 to pump air from the second chamber 222;

[0053] In order to avoid excessive suction in the third chamber 223 and the inner tube 21, the flow valve 482 can control the flow difference for a period of time so that the gas entering the third chamber 223 is equal to the gas required for the expansion of the space between the third chamber 223 and the first chamber 221, that is, the suction is controlled within a certain range.

[0054] Furthermore, a fan-shaped blocking net is installed on the inner wall of the arc plate 211. When multiple sets of arc plates 211 are spliced ​​together to form the inner tube 21, the multiple sets of fan-shaped blocking nets are spliced ​​into a circle and are located above the sample to prevent the sample from moving and rising in the inner tube 21 due to suction.

[0055] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
