These devices are primarily used to detect gases released by products to ensure they meet safety, health, and environmental standards. However, existing gas detection technologies are mostly limited to detection in sealed environments, which restricts their application in certain scenarios.

[0003] However, most current gas detection devices only support detection in a sealed environment, that is, the product to be tested can only be placed inside the box for testing, and cannot adapt to diverse testing needs. For example, when it is necessary to test the gas quality in a large environment, this type of closed detection device is not applicable.

[0004] Based on this, in order to improve the applicability of existing detection devices, we propose a closed automatic detection device for product gas release. Summary of the Invention

DETAILED DESCRIPTION

[0038] 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.

[0039] Reference Figure 1-11 One embodiment of the present invention discloses a closed automatic detection device for product gas release. The detection device is used to implement internal closed detection and current ambient gas detection in the field, thus achieving both internal and external detection, thereby solving the problem that current gas detection devices only support the single function of sealing detection. Specifically, the device includes a machine 1 equipped with a detection chamber 11. In this embodiment, in order to achieve convenient movement of the device, wheels are preferably installed on the bottom of the machine 1 to improve mobility.

[0040] The interior of the detection chamber 11 is slidably connected to a carrier 3 via a driving assembly 2, and the carrier 3 is used to open and close the front end of the detection chamber 11;

[0041] Reference Figure 4 , wherein a wind hood 4 is also installed above the interior of the detection chamber 11, and a detection component 5 and an air induced component 6 are fixed inside the wind hood 4. The machine 1 is also provided with floating door components 7 on both sides of the detection chamber 11, and the floating door components 7 are used to open and close the sides of the detection chamber 11. It should be noted that, in this embodiment, the machine 1 is sealed at the rear side of the detection chamber 11, and the carrier 3 and the two floating door components 7 can respectively seal the front end and both sides of the detection chamber 11, so that after the carrier 3 and the floating door components 7 are completely sealed, an internally sealed detection space is formed inside the detection chamber 11.

[0042] Of course, the air induction component 6 is used to control the flow of gas. When the gas passes through the detection component 5, real-time detection of the gas can be achieved.

[0043] Reference Figure 4 、 Figure 5 、 Figure 6In some embodiments, the driving assembly 2 of the present invention includes a cylinder 21 and an elastic assembly 22, and two of the cylinder 21 and the elastic assembly 22 are provided;

[0044] The axial end of the cylinder 21 is fixedly connected to the carrier 3, and the back end of the cylinder 21 is fixed to the inner side of the detection chamber 11 through the elastic component 22. The design purpose of the elastic component 22 is to facilitate further control of the floating door component 7 when the carrier 3 is subsequently closed. The specific principle will be described in detail later and will not be elaborated here.

[0045] Specifically, in this embodiment, two cylinders 21 are used to control the movement of the carrier 3. When internal inspection is required, the carrier 3 is driven outward by the cylinder 21 to place the product to be tested on the carrier 3. Thereafter, the carrier 3 is driven to reset by the cylinder 21. When the product enters the sealed inspection chamber 11, the air induced component 6 can control the gas flow. When the gas passes through the inspection component 5, real-time detection of the gas released by the product can be achieved.

[0046] Reference Figure 6 Optionally, the elastic component 22 in this embodiment includes a telescopic rod 221 fixed between the detection chamber 11 and the cylinder 21, and the two ends of the telescopic rod 221 are respectively fixed to the inner wall of the detection chamber 11 and the rear end of the cylinder 21, and a spring 222 is sleeved on the outer side of the telescopic rod 221.

[0047] During specific operation, when the cylinder 21 controls the carrier 3 to reset and close the front end of the detection chamber 11, when the front side of the carrier 3 hits the front end part of the machine 1, the carrier 3 is blocked and cannot move. Since the telescopic rod 221 still has a certain amount of activity, the cylinder 21 can be further extended and retracted at this time. Under the limit of the carrier 3, the entire cylinder 21 will start the telescopic rod 221 to extend, and the cylinder 21 will be displaced. With the help of the displacement ability of the cylinder 21, the subsequent drive control of the floating door assembly 7 is facilitated.

[0048] Reference Figure 6 、 Figure 8 On the basis of the above embodiment, the floating door assembly 7 in this embodiment includes a frame 71, and the frame 71 is a rectangular structure with a hollowed-out middle portion;

[0049] Both sides of the machine 1 have mounting positions connected to the detection chamber 11, and the frame 71 is fixed in the mounting positions, wherein a filter plate 72 is fixedly installed inside the frame 71, and the filter plate 72 is used to stop external dust and impurities to prevent foreign matter from entering the detection chamber 11 when detecting external gas, and the upper and lower sides of the frame 71 are connected with drive rods 73 through compression springs 731, and the two drive rods 73 pass through the front end of the frame 71 and are connected to a baffle 74, and the baffle 74 covers the filter plate 72.

[0050] Reference Figure 6 It should be noted that the driving rod 73 described in this embodiment is configured as a U-shaped rod, and any cross-section of the U-shaped rod is configured as a circular structure. Both ends of the U-shaped rod are inserted into and pass through the frame 71, and both ends of the compression spring 731 are connected to the frame 71 and the driving rod 73, so as to reset the driving rod 73 through the provided compression spring 731 after the driving rod 73 is displaced.

[0051] Reference Figure 5 、 Figure 6 In order to realize the linkage control of the above-mentioned cylinder 21 and the driving rod 73, in this embodiment, a rotating shaft 75 is rotatably connected to the inner bottom surface of the detection chamber 11, and an eccentric wheel 76 that contacts the driving rod 73 is fixedly installed on the outer side of the rotating shaft 75. Of course, since the design of two upper and lower driving rods 73 is adopted in this scheme, the eccentric wheels 76 described in this embodiment are installed with two, and the two eccentric wheels 76 are respectively adapted to the two driving rods 73. The eccentric wheels 76 adopt a V-wheel structure design, and the groove surface thereof is clamped on the outer side of the driving rod 73. In this way, when the rotating shaft 75 drives the eccentric wheel 76 to rotate, the driving rod 73 is driven to move linearly by the offset of the eccentric wheel 76.

[0052] Reference Figure 6 A rack portion 23 is fixedly mounted on the side of the cylinder 21 , and a gear 77 is mounted on the outer periphery of the rotating shaft 75 , and the gear 77 is meshed with the rack portion 23 .

[0053] In summary, when internal testing is required, the product to be tested is loaded by opening and closing the carrier 3. When the cylinder 21 drives the carrier 3 to close the detection chamber 11, the air flow can be controlled by the air induction component 6. When the gas released by the product passes through the detection component 5, the gas released by the product can be detected in real time.

[0054] In addition, when external inspection is required, there is no need to load products. When the carrier 3 closes the inspection chamber 11, the cylinder 21 can be further retracted by controlling it. From the above analysis, it can be seen that the front side of the carrier 3 abuts against the front end of the machine 1. Under the limiting effect of the carrier 3, the cylinder 21 will be displaced and pull the telescopic rod 221 to extend. During this process, since the rack portion 23 is fixedly installed on the side of the cylinder 21, when the cylinder 21 moves laterally, the rack portion 23 will engage the gear 77 to drive the rotating shaft 75 to rotate.

[0055] When the rotating shaft 75 rotates, it will move outward by means of the two eccentric wheels 76 against the two driving rods 73. Since the two driving rods 73 are connected to a baffle 74, the baffle 74 will move outward and expose the filter plate 72. At this time, the side of the detection chamber 11 and the external environment are connected, and the front side remains sealed. In this state, the gas flow is controlled by the air induced component 6, and the external environment gas enters the interior of the detection chamber 11 and flows through the detection component 5, so that real-time detection of the external environment gas can be achieved.

[0056] That is, by adopting the above structural design in the present invention, internal and external gases can be detected, thus optimizing the overall applicability.

[0057] Reference Figure 7 It should be noted that, in this embodiment, the inner hole of the gear 77 is provided with a relief opening 771, and the outer side of the rotating shaft 75 is embedded with a key 751, and the key 751 is slidably connected to the relief opening 771. Specifically, the coordination of the relief opening 771 and the key 751 in this embodiment is to provide a coupling lag time between the gear 77 and the rack portion 23, that is, when the cylinder 21 is under a certain amount of movement, the rack portion 23 will mesh with the gear 77 forward, but due to the gear 77 and the rack portion 23, the gear 77 and the rack portion 23 will not engage with the gear 77. There is a clearance 771 between the rotating shaft 75, so the gear 77 is not yet able to drive the rotating shaft 75 to rotate, and therefore will not interfere with the movement of the floating door assembly 7. The purpose of this design is to ensure that the cylinder 21 has a certain amount of free movement when conducting internal inspections. In this way, when the carrier 3 is covered on the front side of the inspection chamber 11, the cylinder 21 will apply a certain pulling force to the carrier 3 to ensure the sealing of the front end of the inspection chamber 11 by the carrier 3, so as to ensure the internal sealing of the entire inspection chamber 11.

[0058] Reference Figure 10In some embodiments, the detection component 5 of the present invention includes a cross bar 51 fixed to the bottom inner side of the air hood 4, and a mounting platform 52 is provided in the middle of the cross bar 51. At least one sensor 53 is installed on the mounting platform 52. Specifically, the sensor 53 in the present invention can be set to multiple, including but not limited to electrochemical sensors, which are used to detect gases such as ammonia (NH3), hydrogen sulfide (H2S), methane (CH4), etc., and are suitable for detecting gases produced during the decomposition of foods with high protein content such as meat and fish; metal oxide semiconductor (MOS) sensors, which are used to be sensitive to multiple gases, such as volatile organic compounds (VOCs) such as ethanol, acetaldehyde, and acetic acid, and are often used to detect the maturity of fruits and vegetables and gases produced during food spoilage; infrared (IR) sensors, which are used to detect carbon dioxide (CO2) and some other specific gases. Changes in CO2 concentration can indicate the respiration and degree of spoilage of food.

[0059] Of course, those skilled in the art can also select sensor types corresponding to the required parameters according to their needs, such as temperature sensors, etc. The above sensor elements are all existing technologies, and their principles will not be described in detail here.

[0060] Of course, in order to realize automatic detection, a display and control unit is further installed on the front side of the machine 1 in the present invention. The display and control unit is electrically connected to each sensor to display the detected gas data in real time.

[0061] Reference Figure 9 、 Figure 10 、 Figure 11 In some embodiments, the induced draft component 6 in the present invention includes an air guide tube 61 inserted into the middle part of the upper side of the wind cover 4, and an induced draft fan 62 is fixedly installed on the inner side of the air guide tube 61; wherein a plurality of air outlets 63 are distributed on the outer circumference of the upper side of the air guide tube 61, and a driving member 64 for driving the air guide tube 61 to move up and down is fixedly installed above the cross bar 51. Preferably, the driving member 64 described in this embodiment can be set to a cylinder or an electric push rod, and the driving member 64 is used to drive the air guide tube 61 to move up and down to realize the exhaust gas discharge at different positions.

[0062] Specifically, the top of the machine 1 has a through hole 12 for avoiding the air guide tube 61;

[0063] When the floating door assembly 7 closes the side of the detection chamber 11, the air outlet 63 of the air guide tube 61 is placed on the inner side of the wind cover 4;

[0064] When the floating door assembly 7 opens the side of the detection chamber 11 , the driving member 64 drives the air guide tube 61 to move out along the through hole 12 until the air outlet 63 is exposed on the upper outside of the machine 1 .

[0065] That is, when the floating door assembly 7 is in the closed state, the internal sealing test is performed. Therefore, in order to accurately detect the internal product gas, the air outlet 63 of the air guide tube 61 is retracted inside the wind cover 4, and the upper side of the air guide tube 61 seals the perforation 12. Therefore, the entire detection chamber 11 is in a closed state, and the air circulates inside the detection chamber 11, thereby realizing the detection of the internal gas.

[0066] Reference Figure 11 When detecting external air, it is necessary to open the floating door assembly 7 and keep the carrier 3 closing the front end of the detection chamber 11. At this time, it is preferred to drive the air guide tube 61 upward so that the air outlet 63 of the air guide tube 61 protrudes from the outside of the machine 1, so that the detection chamber 11 can be connected with the outside. When the draft fan 62 is working, the air flow is discharged upward along the side of the detection chamber 11 through the air outlet 63 to form a circulating detection method in the large environment, avoiding the problem of closed type affecting the detection accuracy of the entire space.

[0067] Reference Figure 5 It should be noted that the carrier 3 in this embodiment is an L-shaped structural member. A sealing ring is installed on the front side of the carrier 3, and the front end opening of the detection cavity 11 is sealed. Of course, a sealing ring can also be installed on the end face of the baffle 74 to ensure the sealing of the connection. In addition, the carrier 3 in this embodiment is slidably connected to the detection cavity 11 through a guide rail and a slider.

[0068] To sum up, in the present invention, a movable carrier 3 is used to place the product to be tested. When the carrier 3 is reset, the detection chamber 11 can be closed, so that the gas of the internal product can be detected. At the same time, when the carrier 3 is reset, the floating door assemblies 7 on both sides can be further opened. At this time, the two sides of the detection chamber 11 are connected to the external environment. When the draft assembly 6 is working, the gas in the current environment can also be detected. This is used to realize internal closed detection and current environmental gas detection in the site, thus achieving internal and external methods to solve the problem that the current gas detection device only supports the singleness of sealing detection.

[0069] 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.
