[0044] Please see Figures 1-12 As shown, a production and testing device for an automotive fragrance system module includes a workbench 1 and a testing cylinder 2 mounted on the top surface of the workbench 1 via a bracket. An electronic nose body 3 is mounted on the top surface of the workbench 1, and the odor detection tube of the electronic nose body 3 is inserted into the interior of the testing cylinder 2. Both ends of the testing cylinder 2 are fixedly connected to sealing plates 5 by bolts. A quick connector 103 is mounted on the surface of one of the sealing plates 5. The odor output end 102 of the fragrance module 101 communicates with the interior of the testing cylinder 2 through the quick connector 103. A friction cleaning component 7 is provided on the top surface of the workbench 1 to clean the inner wall of the testing cylinder 2. A cleaning component 8 is provided inside the friction cleaning component 7 to clean the inner wall of the testing cylinder 2. A heating component 10 is provided inside the friction cleaning component 7 to make the odor particles evaporate faster.

[0045] The components arranged in sequence away from the detection cylinder 2 are the wiping assembly 708, the water absorption assembly 9, the cleaning assembly 8, and the heating assembly 10, which are used to clean the inner wall of the detection cylinder 2.

[0046] The electronic nose body 3, as the core detection component, has its odor detection tube extending deep into the detection cylinder 2, enabling precise capture of fragrance components and ensuring the accuracy of the detection data. Simultaneously, the two ends of the detection cylinder 2 are securely connected to the sealing plates 5 by bolts, facilitating disassembly and maintenance. A quick connector on one of the sealing plates 5 allows for rapid docking with the odor output end 102 of the fragrance module 101, greatly improving the convenience of the detection process. Furthermore, the friction cleaning component 7 and its internal cleaning component 8, mounted on the top surface of the workbench 1, effectively deep clean the inner wall of the detection cylinder 2, preventing residue from interfering with subsequent detection. The heating component 10 inside the friction cleaning component 7 further accelerates the volatilization of odor particles, making the detection process faster and more efficient.

[0047] It should be noted that the detection tube 2 consists of three main parts: sample processing, sample introduction system, detection system, signal processing and pattern recognition system. It is an instrument that uses multiple intelligent sensors to work together to simulate biological olfaction in order to analyze, identify and characterize complex odors or volatile organic compounds.

[0048] The present invention employs a friction cleaning assembly 7, which includes a connecting cylinder 709 disposed above a workbench 1. A positioning cylinder 704 is disposed inside the connecting cylinder 709. A wiping assembly 708 for wiping the inner wall of a wiping detection cylinder 2 is disposed on the surface of the positioning cylinder 704. A positioning frame is fixedly connected to the surface of the positioning cylinder 704 and is slidably connected to the connecting cylinder 709. A cylinder 708-5 is mounted on the top surface of the positioning frame. A sliding sleeve 708-1 is slidably connected to the surface of the positioning cylinder 704. The piston rod of the cylinder 708-5 is fixedly connected to the sliding sleeve 708-1. A number of... A guide rod 708-7 is provided, one end of which is fixedly connected to the positioning frame. Several first force-applying rods 708-2 are evenly distributed and rotatably connected to the surface of the sliding sleeve 708-1 through bearing seats. The end of each first force-applying rod 708-2 away from the sliding sleeve 708-1 is rotatably connected to a first positioning rod 708-8 through a bearing seat. One end of the first positioning rod 708-8 is rotatably connected to the positioning cylinder 704 through a bearing seat. The end of the first positioning rod 708-8 away from the positioning cylinder 704 is fixedly connected to a wiping silicone 708-6, which has a ring structure.

[0049] The surface of the sliding sleeve 708-1 is evenly provided with several sliding grooves 708-4. Each sliding groove 708-4 is slidably connected to a bearing seat, and each bearing seat is rotatably connected to a second force-applying rod 708-3. The end of each second force-applying rod 708-3 away from the sliding sleeve 708-1 is rotatably connected to a second positioning rod 708-9 through a bearing seat. One end of the second positioning rod 708-9 is rotatably connected to the positioning cylinder 704 through a bearing seat, while the other end of the second positioning rod 708-9 is fixedly connected to the wiping silicone 708-6.

[0050] The first positioning rods 708-8 and the second positioning rods 708-9 are staggered, and the rotation angles of the first positioning rods 708-8 and the second positioning rods 708-9 are different.

[0051] When cleaning of the inner wall of the detection cylinder 2 is required, remove the sealing plate 5 at the end of the detection cylinder 2 away from the sealing plate 5, and then connect the connecting cylinder 709 to the detection cylinder 2. After connection, push the positioning cylinder 704 into the detection cylinder 2 until the wiping assembly 708 reaches the other end of the detection cylinder 2. Then, activate the cylinder 708-5. The piston rod of the cylinder 708-5 will push the sliding sleeve 708-1 to slide on the surface of the positioning cylinder 704. The first force rod 708-2 will be pushed by the movement of the sliding sleeve 708-1 to rotate the first positioning rod 708-8 on the surface of the positioning cylinder 704, thereby causing the wiping silicone 708-6 to expand and move. While the sliding sleeve 708-1 is moving, the second force rod 708-3 will slide inside the groove 708-4 until the sliding sleeve 708-1 moves against the second force rod 708-3. After the limit is reached, the second force-applying rod 708-3 will push the second positioning rod 708-9 to rotate on the surface of the positioning cylinder 704, thereby causing the wiping silicone 708-6 to move to the position pulled by the second positioning rod 708-9. Because the first force-applying rod 708-2 and the second force-applying rod 708-3 have the same length but different rotation angles, the wiping silicone 708-6 will not contact the inner wall of the detection cylinder 2 before the sliding sleeve 708-1 moves. When the sliding sleeve 708-1 moves to the top, the wiping silicone 708-6 will fit tightly against the inside of the detection cylinder 2. When the sliding sleeve 708-1 does not move, because the first force-applying rod 708-2 and the second force-applying rod 708-3 have different rotation angles, the wiping silicone 708-6 will not wrinkle when folded, which increases the subsequent cleaning of the wiping silicone 708-6.

[0052] When the wiping silicone 708-6 is in close contact with the inner wall of the detection cylinder 2, pull the positioning cylinder 704 back so that the wiping silicone 708-6 wipes and cleans the inner wall of the detection cylinder 2.

[0053] The present invention employs a friction cleaning assembly 7, which further includes a driving mechanism for pushing the wiping assembly 708. The driving mechanism includes guide rails 702 symmetrically mounted on the top surface of the workbench 1. A movable plate 701 is slidably connected to the top surface of the guide rails 702 via a slider. An electric push rod 703 is mounted on the top surface of the workbench 1. The push rod of the electric push rod 703 is fixedly connected to the movable plate 701. A connecting cylinder 709 is mounted on the top surface of the movable plate 701 via a bracket. A force roller 706 is rotatably connected to the top surface of the movable plate 701 via a bracket. The force roller 706 is located below the positioning cylinder 704. A driven wheel 707 is rotatably connected inside the bracket. The driven wheel 707 is located above the positioning cylinder 704. A motor 705 is mounted on one side of the bracket. The output shaft of the motor 705 passes through the bracket and is fixedly connected to the force roller 706.

[0054] When it is necessary to mate the connecting cylinder 709 with the detection cylinder 2, the electric push rod 703 is activated. The push rod of the electric push rod 703 will move the moving plate 701 towards the detection cylinder 2 via the guide rail 702 until it mates with the detection cylinder 2. Then, in order to allow the wiping assembly 708 to enter the interior of the detection cylinder 2, the motor 705 is activated. The motor 705 will drive the force roller 706 to rotate. The force roller 706 will drive the positioning cylinder 704 to move towards the detection cylinder 2. The driven wheel 707 can limit the positioning cylinder 704, thereby realizing the movement of the wiping assembly 708 into the interior of the detection cylinder 2. Since the inner diameter of the connecting cylinder 709 and the detection cylinder 2 are equal, the axis will not shift when the wiping assembly 708 enters the interior of the detection cylinder 2.

[0055] In this invention, an exhaust fan 4 is installed on the top surface of the workbench 1. The air inlet of the exhaust fan 4 is connected to the interior of the detection cylinder 2, and the exhaust fan 4 is located on the side of the electronic nose body 3 away from the sealing plate 5.

[0056] Before cleaning the inner wall of the detection cylinder 2, remove the sealing plate 5 from its surface, then remove the sealing plate 5, and then start the exhaust fan 4. The exhaust fan 4 will first extract the gas containing odor from inside the detection cylinder 2 to prevent the wiping component 708 from having odor particles sticking to its surface when it enters.

[0057] The present invention employs a cleaning component 8 comprising an annular tube 801 disposed inside a connecting cylinder 709. A plurality of first clamps 804 are uniformly and fixedly connected to the surface of a positioning cylinder 704 by bolts. The annular tube 801 is located inside the first clamps 804. A plurality of atomizing nozzles 802 are uniformly and fixedly connected to the surface of the cleaning component 8 facing the inner wall of the positioning cylinder 704. A connecting water pipe 803 is fixedly connected to the surface of the annular tube 801. The side of the connecting water pipe 803 away from the annular tube 801 is connected to an external water pump.

[0058] After the positioning cylinder 704 enters the interior of the detection cylinder 2, the cleaning component 8 also enters the interior of the detection cylinder 2. When the cleaning of the inner wall of the detection cylinder 2 begins, water is injected into the interior of the connecting water pipe 803 by an external water pump. The water enters the interior of the annular pipe 801 and is atomized and sprayed onto the inner wall of the detection cylinder 2 through the atomizing nozzle 802. The water combines with the odor particles, making it easier for the odor particles to detach from the inner wall of the detection cylinder 2. Then, the water on the inner wall of the detection cylinder 2 is scraped off by the wiping silicone 708-6, thus cleaning the inner wall of the detection cylinder 2. The water also makes the movement of the wiping silicone 708-6 smoother.

[0059] In this invention, the heating assembly 10 includes an annular heating rod 1001 disposed inside the connecting cylinder 709. Several second clamps 1003 are uniformly fixedly connected to the surface of the positioning cylinder 704. The annular heating rod 1001 is located inside the second clamps 1003. An electrical conduit 1002 is fixedly connected to the surface of the annular heating rod 1001. The power cord of the annular heating rod 1001 is connected to an external power source through the electrical conduit 1002.

[0060] When the heating component 10 enters the interior of the detection cylinder 2, the annular heating rod 1001 is energized by the external power supply, causing the annular heating rod 1001 to generate heat. The higher the temperature, the greater the average kinetic energy of the gas molecules, the faster their movement speed, and the faster the diffusion speed, making it easier for odor particles to detach. The heated inner wall of the detection cylinder 2 will heat the water mist from the atomizing nozzle 802 to a certain extent, so that the wiping silicone 708-6 becomes softer due to the increased temperature when wiping away water, making the wiping silicone 708-6 adhere more tightly to the inner wall of the detection cylinder 2.

[0061] In this invention, a water-absorbing component 9 is provided inside the connecting cylinder 709; the water-absorbing component 9 includes a water-collecting head 901 embedded in the surface of the positioning cylinder 704, the bottom end of the water-collecting head 901 facing the atomizing nozzle 802, and a water-absorbing pipe 902 fixedly connected to the top surface of the water-collecting head 901, which is connected to an external water pump.

[0062] The water that is scraped off and the excess water will enter the interior of the suction pipe 902 through the water collection head 901, and then be discharged by the external water pump, thereby preventing water from flowing out of the interior of the detection cylinder 2 and contaminating the top surface of the workbench 1.

[0063] It should be noted that the annular heating rod 1001 is existing technology, and contains a resistance wire made of nickel-chromium alloy. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0064] It should be noted that motor 705 is a servo motor with an encoder, and the number of rotations and rotation angle of the motor output shaft are controllable and highly accurate. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0065] It should be noted that the electric actuator 703 can be used with magnetic switches, proximity switches or photoelectric switches to achieve precise control of the actuator's extension and retraction displacement. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0066] It should be noted that the cylinder 708-5 is a power actuator that converts the pressure energy of compressed air into mechanical energy. By controlling the gas inlet and outlet, it drives the piston to perform linear reciprocating motion. It can be used in conjunction with a magnetic switch, proximity switch or photoelectric switch to achieve precise control of the cylinder piston rod extension and retraction displacement. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0067] The present invention is used in the following steps:

[0068] S1: When it is necessary to detect the odor of the fragrance module 101, first connect the output terminal 102 of the fragrance module 101 to the quick connector 103, then place the fragrance cartridge inside the fragrance module 101, and then let the fragrance module 101 exhaust into the detection tube 2. After the gas has spread for a period of time, its odor detection tube penetrates into the detection tube 2. The electronic nose body 3, as the core detection component, can accurately capture the fragrance components and analyze, identify and identify them by simulating biological olfaction through internal intelligent sensors, thereby ensuring the accuracy of the detection data.

[0069] S2: When it is necessary to dock the connecting cylinder 709 with the detection cylinder 2, the electric push rod 703 is started. The push rod of the electric push rod 703 will move the moving plate 701 towards the detection cylinder 2 through the guide rail 702 until it docks with the detection cylinder 2. Then, in order to allow the wiping assembly 708 to enter the interior of the detection cylinder 2, the motor 705 is started. The motor 705 will drive the force roller 706 to rotate. The force roller 706 will drive the positioning cylinder 704 to move towards the detection cylinder 2. The driven wheel 707 can limit the positioning cylinder 704, thereby realizing the movement of the wiping assembly 708 into the interior of the detection cylinder 2. Since the inner diameter of the connecting cylinder 709 and the detection cylinder 2 are equal, the axis will not shift when the wiping assembly 708 enters the interior of the detection cylinder 2.

[0070] S3: When it is necessary to clean the inner wall of the detection cylinder 2, remove the sealing plate 5 at the end of the detection cylinder 2 away from the sealing plate 5, and then connect the connecting cylinder 709 to the detection cylinder 2. After the connection is completed, push the positioning cylinder 704 into the detection cylinder 2 until the wiping assembly 708 reaches the other end of the detection cylinder 2. Then, start the cylinder 708-5. The piston rod of the cylinder 708-5 will push the sliding sleeve 708-1 to slide on the surface of the positioning cylinder 704. The first force rod 708-2 will push the first positioning rod 708-8 to rotate on the surface of the positioning cylinder 704 due to the movement of the sliding sleeve 708-1, thereby causing the wiping silicone 708-6 to expand and move. While the sliding sleeve 708-1 moves, the second force rod 708-3 will slide inside the sliding groove 708-4 until the sliding sleeve 708-1 pushes the second force rod 708-3. After the limit is reached, the second force rod 708-3 will push the second positioning rod 708-9 to rotate on the surface of the positioning cylinder 704, thereby causing the wiping silicone 708-6 to move to the position pulled by the second positioning rod 708-9. Because the first force rod 708-2 and the second force rod 708-3 have the same length but different rotation angles, the wiping silicone 708-6 will not contact the inner wall of the detection cylinder 2 before the sliding sleeve 708-1 moves. When the sliding sleeve 708-1 moves to the top, the wiping silicone 708-6 will fit tightly against the inside of the detection cylinder 2. When the sliding sleeve 708-1 does not move, because the first force rod 708-2 and the second force rod 708-3 have different rotation angles, the wiping silicone 708-6 will not wrinkle when folded, which increases the subsequent cleaning of the wiping silicone 708-6.

[0071] S4: Before cleaning the inner wall of the detection cylinder 2, remove the sealing plate 5 from the surface of the sealing plate 5, then remove the sealing plate 5, and then start the exhaust fan 4. The exhaust fan 4 will first extract the gas containing odor inside the detection cylinder 2 to prevent the surface of the wiping component 708 from sticking with odor particles when it enters.

[0072] S5: When the positioning cylinder 704 enters the interior of the detection cylinder 2, the cleaning component 8 will also enter the interior of the detection cylinder 2. When the cleaning of the inner wall of the detection cylinder 2 begins, water is injected into the interior of the connecting water pipe 803 by an external water pump. The water will enter the interior of the annular pipe 801 and be atomized and sprayed onto the inner wall of the detection cylinder 2 through the atomizing nozzle 802. The water and odor particles combine with each other, making it easier for the odor particles to detach from the inner wall of the detection cylinder 2. Then, the water on the inner wall of the detection cylinder 2 is scraped off by the wiping silicone 708-6, thereby cleaning the inner wall of the detection cylinder 2. The water also makes the movement of the wiping silicone 708-6 smoother.

[0073] S6: When the heating component 10 enters the interior of the detection cylinder 2, the external power supply is turned on to energize the annular heating rod 1001, causing the annular heating rod 1001 to generate heat. The higher the temperature, the greater the average kinetic energy of the gas molecules, the faster their movement speed, and the faster the diffusion speed, making it easier for odor particles to detach. The heated inner wall of the detection cylinder 2 will heat the water mist from the atomizing nozzle 802 to a certain extent, so that the wiping silicone 708-6 becomes softer due to the increased temperature when scraping water, making the wiping silicone 708-6 adhere more tightly to the inner wall of the detection cylinder 2.

[0074] S7: The water that is scraped off and the excess water will enter the interior of the suction pipe 902 through the water collection head 901, and then be discharged by the external water pump, thereby preventing water from flowing out of the interior of the detection cylinder 2 and contaminating the top surface of the workbench 1.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
