[0001] The present application relates to the technical field of gas detection devices, and in particular to a closed automatic detection device for product released gas. BACKGROUND

[0002] In today's technical field, gas detection devices play a crucial role in numerous industries and applications. These devices are primarily used to detect the gas released by products to ensure that they meet safety, health, and environmental standards. However, existing gas detection technologies are mostly limited to detection in sealed environments, which limits their application in certain specific scenarios.

[0003] However, most current gas detection devices only support detection in a sealed environment, i.e., they can only detect the product to be tested by placing it inside the box, which cannot adapt to diversified detection needs. For example, when the gas quality in a large environment needs to be detected, such closed detection devices are not applicable.

[0004] Therefore, in order to improve the applicability of existing detection devices, we propose a closed automatic detection device for product released gas. SUMMARY

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0039] Reference Figures 1-11 For an embodiment of the present application, an enclosed automatic detection device for product released gas is disclosed, which is used to realize internal enclosed detection and current environmental gas detection in a site, so as to achieve internal and external two ways to solve the problem of single sealing detection supported by the current gas detection device. Specifically, the device comprises a machine table 1 provided with a detection cavity 11. In the embodiment, in order to realize convenient movement of the device, a wheel is preferably installed at the bottom of the machine table 1 to improve the mobility.

[0040] The inside of the detection cavity 11 is slidably connected with a carrier 3 through a driving assembly 2. The carrier 3 is used to open and close the front end of the detection cavity 11.

[0041] Reference Figure 4 The inside of the detection cavity 11 is slidably connected with a carrier 3 through a driving assembly 2. The carrier 3 is used to open and close the front end of the detection cavity 11.

[0042] Of course, the air guiding assembly 6 is used to control the flow of gas, and when the gas passes through the detection assembly 5, real-time detection of the gas can be realized.

[0043] Reference Figure 4 , Figure 5 , Figure 6In some embodiments, the driving assembly 2 in the present application comprises a cylinder 21 and an elastic assembly 22, both of which are provided with two;

[0044] The shaft end of the cylinder 21 is fixedly connected with the platform 3, and the back end of the cylinder 21 is fixed on the inner side of the detection cavity 11 through the elastic assembly 22. The design of the elastic assembly 22 is to facilitate the further control of the floating door assembly 7 when the platform 3 is closed subsequently. The specific principle will be described in detail later, and will not be described here.

[0045] Specifically, two cylinders 21 are adopted in the present embodiment to control the movement of the platform 3. When internal detection is needed, the platform 3 is driven by the cylinder 21 to move outward, and the product to be detected is placed on the platform 3. Then the platform 3 is reset by the cylinder 21. When the product enters the sealed detection cavity 11, the air guide assembly 6 controls the flow of gas. When the gas passes through the detection assembly 5, real-time detection of the gas released by the product can be realized.

[0046] Referring to Figure 6 Optionally, the elastic assembly 22 in the present embodiment comprises a telescopic rod 221 fixed between the detection cavity 11 and the cylinder 21, both ends of the telescopic rod 221 are fixed on the inner wall of the detection cavity 11 and the back end of the cylinder 21 respectively, and a spring 222 is sleeved outside the telescopic rod 221.

[0047] In specific work, when the cylinder 21 controls the platform 3 to reset and close the front end of the detection cavity 11, the front side of the platform 3 is in contact with the front end of the machine table 1, at this time the platform 3 is hindered and cannot move. However, the telescopic rod 221 still has a certain amount of movement, so that the cylinder 21 can further stretch at this time. Under the limit of the platform 3, the telescopic rod 221 of the entire cylinder 21 will be stretched, and the cylinder 21 will be displaced. With the displacement ability of the cylinder 21, the subsequent driving control of the floating door assembly 7 is facilitated.

[0048] Referring to Figure 6 、 Figure 8 On the basis of the above-mentioned embodiment, the floating door assembly 7 in the present embodiment comprises a frame 71, which is a rectangular structure with a hollow middle part.

[0049] The machine table 1 has installation positions on both sides which communicate with the detection cavity 11, the frame 71 is fixed in the installation position, wherein the inside of the frame 71 is fixedly installed with a filter plate 72, the filter plate 72 is used for stopping dust and impurities from the outside, so as to avoid foreign matters from entering the inside of the detection cavity 11 when detecting the outside gas, and the upper and lower sides of the frame 71 are both inserted with a driving rod 73 through a compression spring 731, the two driving rods 73 penetrate to the front end of the frame 71 and are commonly connected to a baffle 74 which covers the filter plate 72.

[0050] With reference to Figure 6 It should be noted that the driving rod 73 in the embodiment is provided as a U-shaped rod, any cross section of the U-shaped rod is provided as a circular structure, both ends of the U-shaped rod are inserted and penetrate 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 compression spring 731 after displacement of the driving rod 73.

[0051] With reference to Figure 5 , Figure 6 In order to realize linkage control of the cylinder 21 and the driving rod 73, a rotating shaft 75 is rotatably connected to the inner bottom surface of the detection cavity 11, an eccentric wheel 76 which abuts against the driving rod 73 is fixedly installed on the outer side of the rotating shaft 75, of course, since two driving rods 73 are designed in the embodiment, two eccentric wheels 76 are installed in the embodiment, the two eccentric wheels 76 are adapted to the two driving rods 73 respectively, the eccentric wheel 76 is designed as a V-shaped wheel structure, and the recessed surface of the eccentric wheel 76 is sleeved on the outer side of the driving rod 73, so that when the rotating shaft 75 drives the eccentric wheel 76 to rotate, the eccentric wheel 76 drives the driving rod 73 to move linearly through the offset amount of the eccentric wheel 76.

[0052] With reference to Figure 6 The side of the cylinder 21 is fixedly installed with a rack portion 23, and a gear 77 is installed on the outer periphery of the rotating shaft 75, the gear 77 and the rack portion 23 are engaged.

[0053] In summary, when internal detection is needed, the product to be detected is loaded through the opening and closing movement of the table 3, when the cylinder 21 drives the table 3 to close the detection cavity 11, the gas flow can be controlled through the air guiding assembly 6, and when the gas released by the product passes through the detection assembly 5, real-time detection of the gas released by the product can be realized.

[0054] Further, when external detection is needed, at this time, without loading products, in the state that the platform 3 closes the detection cavity 11, the further contraction of the air cylinder 21 can be controlled, and according to the above analysis, the front side of the platform 3 abuts against the front end of the machine table 1, and under the limiting action of the platform 3, the air cylinder 21 will displace and pull the telescopic rod 221 to elongate, in this process, since the side edge of the air cylinder 21 is fixedly installed with the rack part 23, when the air cylinder 21 transversely moves, the rack part 23 will engage the gear 77 to drive the rotation of the rotating shaft 75;

[0055] When the rotating shaft 75 rotates, the two eccentric wheels 76 abut against the two driving rods 73 to move outward, since the two driving rods 73 are jointly connected to a baffle plate 74, therefore the baffle plate 74 will move outward and expose the filter plate 72, at this time, the side edge of the detection cavity 11 is communicated with the external environment, while the front side remains sealed, in this state, the gas flow is controlled by the air guide assembly 6, the external environment gas enters the inside of the detection cavity 11 and flows through the detection assembly 5, and the real-time detection of the external environment gas can be realized.

[0056] That is to say, by adopting the above structure design, the internal and external gases can be detected, and thus the overall applicability is optimized.

[0057] Referring to Figure 7 It should be noted that the inner hole of the gear 77 is provided with an avoiding opening 771, the outer side of the rotating shaft 75 is embedded with a key 751, and the key 751 is slidingly connected in the avoiding opening 771, specifically, in the embodiment, the avoiding opening 771 and the key 751 are matched, so that the gear 77 and the rack part 23 have a coupling lag time, that is, when the air cylinder 21 moves a certain amount, the rack part 23 will engage the gear 77 forward, but since there is an avoiding opening 771 between the gear 77 and the rotating shaft 75, at this time, the gear 77 cannot drive the rotating shaft 75 to rotate, and therefore will not interfere with the movement of the floating door assembly 7, the purpose of the design is to ensure that the air cylinder 21 has a certain amount of free movement when internal detection is performed, so that when the platform 3 covers the front side of the detection cavity 11, the air cylinder 21 will apply a certain pulling force to the platform 3, so as to ensure the sealing performance of the platform 3 to the front end of the detection cavity 11, so as to ensure the internal sealing performance of the entire detection cavity 11.

[0058] Referring to Figure 10In some embodiments, the detection assembly 5 in the present application comprises a horizontal rod 51 fixed to the inner bottom of the wind cover 4, and a mounting table 52 is arranged at the middle of the horizontal rod 51, and at least one sensor 53 is arranged on the mounting table 52. Specifically, the sensor 53 in the present application can be arranged in multiple numbers, including but not limited to an electrochemical sensor for detecting gases such as ammonia (NH3), hydrogen sulfide (H2S), methane (CH4), etc., which is suitable for detecting gases generated during the decomposition of foods with high protein content such as meat and fish; a metal oxide semiconductor (MOS) sensor for being sensitive to various gases such as ethanol, acetaldehyde, acetic acid, etc. volatile organic compounds (VOCs), which is commonly used for detecting the maturity of fruits and vegetables and the gases generated during the spoilage of foods; and an infrared (IR) sensor for detecting carbon dioxide (CO2) and some other specific gases, and the change of the concentration of CO2 can indicate the respiration and spoilage degree of foods.

[0059] Of course, the person skilled in the art can also select the sensor type corresponding to the required parameter according to the requirement, such as a temperature sensor, etc. The above sensor elements are all prior art, and the principle thereof will not be described here.

[0060] Of course, in order to realize automatic detection, a display and control unit is also arranged at the front side of the machine table 1, and the display and control unit is electrically connected with each sensor to display the detected gas data in real time.

[0061] With reference to Figure 9 , Figure 10 , Figure 11 In some embodiments, the air guiding assembly 6 in the present application comprises an air duct 61 inserted into the middle of the upper side of the wind cover 4, and an air guiding fan 62 is fixedly arranged at the inner side of the air duct 61; wherein a plurality of air outlets 63 are distributed around the upper side of the air duct 61, and a driving member 64 for driving the air duct 61 to move up and down is fixedly arranged above the horizontal rod 51. As a preferred embodiment, the driving member 64 can be arranged as a pneumatic cylinder or an electric push rod, which is used to drive the air duct 61 to move up and down so as to realize the exhaust of tail gas at different positions.

[0062] Specifically, the machine table 1 has a perforation 12 above which the air duct 61 is arranged;

[0063] When the floating door assembly 7 closes the side of the detection cavity 11, the air outlets 63 of the air duct 61 are arranged at the inner side of the wind cover 4;

[0064] When the floating door assembly 7 opens the side of the detection cavity 11, the driving member 64 drives the air duct 61 to move out along the perforation 12 until the air outlets 63 are exposed to the outside of the machine table 1.

[0065] That is to say, when the floating door assembly 7 is in the closed state, this is the internal sealing detection, therefore in order to the detection accuracy of the internal product gas, the air outlet 63 of the air duct 61 is retracted in the inner side of the air cover 4, and the upper side of the air duct 61 seals the perforation 12, therefore the whole detection cavity 11 is in the closed state at this time, the air flow circulates in the inside of the detection cavity 11, that is, the detection of the internal gas can be realized;

[0066] Referring to Figure 11 When the external gas is detected, the floating door assembly 7 needs to be opened and the front end of the detection cavity 11 is closed by the platform 3, at this time, the air duct 61 is preferably driven upward, so that the air outlet 63 of the air duct 61 protrudes out of the machine table 1, so that the detection cavity 11 is communicated with the outside, when the air blower 62 works, the air flow is discharged along the side of the detection cavity 11 upward through the air outlet 63, to form a circulating detection mode in the whole environment, avoiding the problem of affecting the detection accuracy of the whole space in the closed mode.

[0067] Referring to Figure 5 It should be noted that the platform 3 in the embodiment is an L-shaped structure, a sealing ring is mounted on the front side of the platform 3 and seals the front end opening of the detection cavity 11, of course, a sealing ring can also be mounted on the end face of the baffle 74 to ensure the sealing of the connection, in addition, the platform 3 in the embodiment is slidably connected in the detection cavity 11 through a guide rail and a sliding block.

[0068] In summary, in the present application, the platform 3 that can be moved is used to place the product to be detected, when the platform 3 is reset, the detection cavity 11 can be closed, so that the detection of the gas of the internal product can be realized, at the same time, when the platform 3 is reset, the two floating door assemblies 7 can be further opened, at this time, the two sides of the detection cavity 11 are communicated with the external environment, when the air blower assembly 6 works, the gas in the current environment can also be detected, so as to realize the internal closed detection and the detection of the gas in the current environment in the site, so as to achieve the internal and external two modes, to solve the problem of the single detection of the current gas detection device.

[0069] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
