[0058] like Figure 2 As shown, the first frame 4 is also equipped with a purification pipe 15, a drying pipe 16, and a flow meter 17. The purification pipe 15, the drying pipe 16, and the flow meter 17 are connected to the air intake pipe. The purification pipe 15, the drying pipe 16, and the flow meter 17 are arranged in the first frame 4. The reasonable position setting makes it easy to connect the purification pipe 15, the drying pipe 16, and the flow meter 17 to the air intake pipe, so as to achieve the purification, drying, and flow control of the air intake of the odor source box 5. Figure 2 As shown, in this embodiment, two flow meters 17 are provided, which are respectively provided on the air inlet pipe and the air outlet pipe, to control the flow entering the odor source box 5 and the flow flowing out of the odor source box 5, respectively. A purification tank 18 is provided on the second desktop 8, and the purification tank 18 is connected to the air outlet pipe. The purification tank 18 is provided on the second desktop 8, and the purification tank 18 is connected to the air outlet pipe to further purify the gas flowing out of the odor source box 5, to ensure the cleanliness of the gas flowing to the olfactory identification device 14 and the gas analyzer 13, and to reduce the impact of the gas on the human body or equipment. It should be noted that, Figure 2 The specific pipeline connection is not shown in the figure. The air intake pipeline referred to herein refers to the pipeline connected from the air intake device 6 to the odor source box 5, and the air outlet pipeline refers to the pipeline connected from the odor source box 5 to the purification tank 18.

[0059] like Figure 2As shown, a temperature transmitter 24 is further provided in the second frame 9. The temperature transmitter 24 is connected to the gas outlet pipe and is located upstream of the purification tank 18. The second frame 9 is also provided with a temperature transmitter 24. The temperature transmitter 24 is connected to the gas outlet pipe and is located upstream of the purification tank 18. The temperature transmitter 24 is used to control the temperature of the gas flowing from the gas outlet pipe to the purification tank 18.

[0060] In this embodiment, the air intake device 66 adopts an air compressor, but in other embodiments, the air intake device 66 can also be a device with a gas pumping function such as a blower.

[0061] like Figure 2 As shown, a gas-liquid separation device 11 is also provided in the second frame 9, a water tank 7 is provided in the first frame 4, and a water supply port 12 and a return water port are provided on the gas-liquid separation device 11. The water in the water tank 7 is transported to the water supply port 12 of the gas-liquid separation device 11, and the precipitated water returns to the water tank 7 through the return water port provided on the gas-liquid separation device 11, that is, the water tank 7 supplies water to the gas-liquid separation device 11 and receives the return water of the gas-liquid separation device 11. The gas-liquid separation device 11 is connected to the bypass pipe, and the air inlet of the bypass pipe is connected to one end of the air outlet pipe close to the odor source box 5 through a valve, and the air outlet of the bypass pipe is connected upstream of the temperature transmitter 24. A gas-liquid separation device 11 is disposed within the second frame 9, a water tank 7 is disposed within the first frame 4, and a bypass pipe is provided to connect the gas-liquid separation device 11. This allows for quantitative and qualitative analysis of a gas containing a certain mixture of gas and water (e.g., odorous gas generated by a hot pot), which enters the gas-liquid separation device 11 through the bypass to remove moisture, then flows to the temperature transmitter 24 for temperature adjustment before being sent to the purification tank 18. Finally, it enters the gas analyzer 13 or the olfactory identification device 14, respectively. The water tank 7 supplies water to the gas-liquid separation device 11 and receives the return water from the gas-liquid separation device 11, thereby achieving gas-water separation. In this embodiment, a bypass pipe is provided. When the odor source to be smelled and analyzed requires gas-water separation, a valve is opened to connect the bypass pipe to the odor source box 5, while the outlet pipe side is closed, allowing the gas to undergo gas-liquid separation through the gas-liquid separation device 11 in the bypass pipe before being sent to the olfactory identification device 14 and the gas analyzer 13.

[0062] The first frame 4, the first table top 3, the second frame 9 and the second table top 8 are all made of aluminum profiles. This allows the entire first table body 1 and the second table body 2 to have a certain load-bearing function, which can carry the required related components and can also place temporary items, with good load-bearing capacity.

[0063] The front and left and right sides of the first and second frames (4) are enclosed with transparent acrylic panels, while the rear of the first and second frames is hollowed out. Using transparent acrylic panels as the table body, wrapped around the sides, not only creates an aesthetically pleasing surface, but also protects the internal experimental components and pipes from collisions, allowing for real-time monitoring of the operating status of each component. The rear of the first and second frames is hollowed out, and the back of the table is hollowed out to facilitate the replacement of experimental components.

[0064] The odor source box 5 includes a door panel with two operation holes 19 provided thereon. The distance between the two operation holes 19 and the ground is between 1m and 1.3m, and the center distance between the two operation holes 19 is between 35cm and 45cm. The odor source box 5 includes a door panel. When the door panel is closed, the odor source box 5 is a closed structure, so that the odorous gas in the odor source box 5 is smoothly delivered to the olfactory identification device 14 or the gas analyzer 13 through the exhaust channel under the action of the air intake device 6. The odor source box 5 is provided with two operation holes 19. The operation holes 19 have an opening and closing transparent panel, which is convenient for opening and operating, such as stirring or turning. The transparent setting also facilitates manual observation when closed, such as placing an odor source such as hot pot or durian into the positive pressure box for operation. The distance between the two operation holes 19 and the ground is controlled to be between 1m and 1.3m, and the distance between the two operation holes 19 is controlled to be between 35cm and 45cm. The setting is based on the height range of the human body to make manual operation more comfortable.

[0065] An air intake hole and an exhaust hole are provided on the first desktop 3. The air intake pipe passes through the air intake hole and is connected to the odor source box 5. The exhaust pipe passes through the exhaust hole, so that the exhaust of the odor source box 5 is connected to the gas analyzer 13 or the olfactory identification device 14; a dry delivery pipe is also provided in the second frame 9, and a through hole is also provided on the second desktop 8 for the delivery pipe to be connected to the purification tank 18, so as to realize the connection between the experimental components above the first desktop 3 and the experimental components above the second desktop 8, such as the connection of the odor source box 5, the purification tank 18, etc., to avoid the pipeline being exposed to the outside to protect the pipeline.

[0066] like Figure 1 、 Figure 4 As shown, a slide rail 20 is provided on the back panel 10, and a slider 21 is provided on the olfactory device 14 to cooperate with the slide rail 20. The slider 21 cooperates with the slide rail 20 to enable the olfactory device 14 to be assembled and disassembled, facilitating the removal and placement of the olfactory device. The olfactory port 23 is located at the top of the olfactory device 14 and is set 1.3 meters above the ground. Setting the olfactory port 23 at a height that is generally easy to smell reduces the possibility of the olfactory user bending over. Of course, in other embodiments, the olfactory port 23 can be set within a range of 1.2 meters to 1.4 meters above the ground.

[0067] like Figure 1-Figure 3As shown, the odor source box 5 is arranged above the first table body 1 through the support rod 25. The arrangement of the support rod 25 can ensure that the odor source box 5 can be at a suitable height on the basis of increasing the height of the first frame 4, thereby reducing costs.

[0068] Preferably, the size of the second table body 2 in the front-to-back direction is smaller than that of the first table body 1, which not only saves space but also makes it convenient for olfactory personnel to perform olfactory operations in the front; the first table body 1 and the second table body 2 are fixedly arranged on an L-shaped base plate 22, and a pulley is provided at the bottom of the base plate, so that the first table body 1 and the second table body 2 are integrated, making the structure more compact, and a pulley is provided at the bottom of the base plate, which can easily realize the movement and relocation of the olfactory laboratory bench.

[0069] When the olfactory identification test bench provided by the present invention is in use, an air collecting bag or an object to be gas-collected (such as durian, boiling hot pot, etc.) is placed in the odor source box 5, and the air compressor is connected to the odor source box 5 via an air inlet pipe connected to equipment such as a purification pipe 15, a drying pipe 16, and a flow meter 17. The air compressor is started to increase the pressure in the odor source box 5, and the collected gas is squeezed into the air outlet pipe. In this process, the purification pipe 15 and the drying pipe 16 are used to purify and dry the gas entering the odor source box 5. If the odor source box 5 contains an air collecting bag containing odorous gas, no inlet and outlet pipes are required. The water treatment is directly transmitted through the outlet pipe through the temperature transmitter 24, the purification tank 18 and other treatments, and then divided into two routes to be respectively transported to the gas analyzer 13 for quantitative analysis and to the olfactory identification device 14 for manual olfactory identification; if the odorous gas in the odor source box 5 needs to be dehydrated, the bypass pipe is opened, and the gas in the odor source box 5 is transported to the gas-liquid separation device 11 for treatment, and then processed through the temperature transmitter 24, the purification tank 18 and other treatments, and then divided into two routes to be respectively transported to the gas analyzer 13 for quantitative analysis and to the olfactory identification device 14 for manual olfactory identification, thereby realizing the integration of quantitative analysis and qualitative analysis.
