Description

Technical Field

[0001] This utility model belongs to the field of odor detection technology, and specifically relates to an odor auxiliary detection device. Background Technology

[0002] Odor and taste problems in water bodies, especially those caused by algal metabolites such as geosmin and 2-methylisoborneol, are key factors affecting the sensory quality and public acceptance of drinking water. Currently, the common method for detecting odor and taste in water bodies is to heat the collected water sample to release volatile odor markers, and then use a gas sensor to detect and identify the generated vapor.

[0003] However, in practical applications, the concentration of odor substances changes with water temperature stratification. Therefore, in order to ensure the representativeness of the samples, it is usually necessary to collect multiple samples from different locations and depths in the water. When the samples collected from multiple points are mixed and heated for testing, the amount of water sample added at multiple locations is prone to deviation, and the samples will stratify and be difficult to mix on their own. As a result, the vapor components escaping from the surface of the mixed sample during the subsequent heating process cannot accurately represent the preset average concentration of the samples at each location, thus leading to deviations in the test results. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide an odor-aided detection device to solve the aforementioned issues.

[0005] To achieve the above objectives, an odor-assisted detection device includes a detection box. A partition plate is installed inside the detection box, and a vent hole is provided at the top of the partition plate. A mixing cylinder and a heating cylinder are installed on one side of the partition plate, and a detection chamber is provided on the other side of the partition plate. A first cover plate and a second cover plate are detachably connected to the top of the detection box. A water distribution chamber is installed on the top of the first cover plate, and two equalizing plates are installed inside the water distribution chamber. A water collection chamber is installed inside the water distribution chamber. A stirring rod is provided inside the mixing cylinder, and a sealing gasket is installed at the bottom of the stirring rod.

[0006] Preferably, a barrier block is installed between the mixing cylinder and the heating cylinder, and the sealing gasket is slidably disposed inside the barrier block.

[0007] Preferably, a drain rod is slidably connected to the bottom of the detection box.

[0008] Preferably, a drive chamber is installed on the top of the second cover plate, and a transmission block is rotatably connected to the bottom of the second cover plate, the transmission block being engaged with the top of the stirring rod.

[0009] Preferably, a water inlet is installed at the bottom of the cover plate.

[0010] Preferably, both the first cover plate and the second cover plate are equipped with positioning blocks at their bottoms, and the positioning blocks are slidably connected to the inside of the mixing cylinder.

[0011] Preferably, a sealing frame is provided inside the water distribution chamber, and three drain pipes are installed on one side of the water distribution chamber.

[0012] The utility model has the following beneficial effects: By cooperating with the three internal chambers of the water distribution chamber and other components such as the water collection chamber, water samples collected from different locations can be introduced into different areas, and excess water can be directly discharged to ensure that the water volume in the three chambers is consistent, thus ensuring the representativeness of the water samples tested later. Furthermore, mixed water samples from different locations can be thoroughly mixed by stirring components such as the stirring rod to ensure the accuracy of the final test results.

[0015] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0016] Example: Figure 1—5 shows: An odor-assisted detection device, including a detection box 1, a partition plate 11 installed inside the detection box 1, a vent hole 111 opened on the top of the partition plate 11, a mixing cylinder 12 and a heating cylinder 13 installed on one side of the partition plate 11, a detection chamber 14 provided on the other side of the partition plate 11, a cover plate 2 and a cover plate 21 detachably connected to the top of the detection box 1, a water distribution chamber 3 installed on the top of the cover plate 2, two equalizing plates 31 installed inside the water distribution chamber 3, a water collection chamber 32 installed inside the water distribution chamber 3, a stirring rod 4 provided inside the mixing cylinder 12, and a sealing gasket 41 installed at the bottom of the stirring rod 4.

[0017] The detection box 1 serves as the basic supporting component of the entire device, providing installation and protection space for the internal components. A partition plate 11 is fixedly installed inside the detection box 1, dividing the interior into different functional areas. The partition plate 11 has several ventilation holes 111 to allow gas flow between different areas, ensuring the transmission of odor vapors. A mixing cylinder 12 and a heating cylinder 13 are fixedly installed on one side of the partition plate 11. The mixing cylinder 12 is used to mix multiple water samples, while the heating cylinder 13 has a built-in heating element to heat the water sample, causing the volatile odor markers to escape. A detection chamber is located on the other side of the partition plate 11. 14. A suitable gas sensor is installed inside the detection chamber 14 according to actual needs to detect and identify the odor vapor generated after heating. A cover plate 1 (2) and a cover plate 2 (21) are detachably connected to the top of the detection box 1. A water distribution chamber 3 is integrally formed on the top of the cover plate 1 (2). The water distribution chamber 3 is used to initially distribute multiple water samples to be tested. Two equalizing plates 31 are fixedly installed inside the water distribution chamber 3. The two equalizing plates 31 are symmetrically distributed, dividing the interior of the water distribution chamber 3 into three equal-volume chambers, ensuring that water samples collected from different locations can enter the mixing cylinder 12 evenly according to a preset ratio. A water collecting chamber 32 is installed inside the water distribution chamber 3, and the water collecting chamber 32 is connected to the three chambers. The system connects the water samples, allowing them to be collected and uniformly introduced into the mixing cylinder 12. Inside the mixing cylinder 12, a stirring rod 4 is movably mounted. The stirring rod 4 can rotate around its own axis to stir the multiple water samples within the mixing cylinder 12, preventing stratification. A sealing gasket 41, made of water-resistant rubber, is fitted and adhered to the bottom of the stirring rod 4, ensuring a tight seal with the inner wall of the mixing cylinder 12 and preventing leakage. During use, the operator first places the cover plate 2 over the mixing cylinder 12, then introduces water samples from different locations into the three cavities inside the water distribution chamber 3. Once the three cavities are full of water, the water... The sample enters the water collection tank 32 and then the mixing cylinder 12. The staff then places the cover plate 21 on top of the mixing cylinder 12. At this time, the drive unit installed on the cover plate 21 will drive the stirring rod 4 to rotate inside the mixing cylinder 12. After the water sample inside the mixing cylinder 12 is mixed, the staff removes the stirring rod 4 from the mixing cylinder 12. The mixed water sample inside the mixing cylinder 12 will enter the heating cylinder 13. After the water sample inside the heating cylinder 13 is heated and evaporated, the steam will enter the mixing cylinder 12 and then enter the detection chamber 14 through the vent 111. Finally, the sensor installed inside the detection chamber 14 will complete the detection of the odor marker.

[0018] A barrier block 15 is installed between the mixing cylinder 12 and the heating cylinder 13, and a sealing gasket 41 is slidably disposed inside the barrier block 15. The barrier block 15 is fixedly installed between the mixing cylinder 12 and the heating cylinder 13, and a water sample flow channel is opened inside the barrier block 15. One end of the channel is connected to the bottom of the mixing cylinder 12, and the other end is connected to the top of the heating cylinder 13, so that after the stirring rod 4 is removed, the water sample in the mixing cylinder 12 can flow into the heating cylinder 13 along the channel. The sealing gasket 41 at the bottom of the stirring rod 4 is slidably disposed inside the barrier block 15. In the stirring state, the sealing gasket 41 can block the flow channel between the mixing cylinder 12 and the heating cylinder 13 to prevent the water sample from flowing into the heating cylinder 13 in advance. When the stirring is completed and the stirring rod 4 is removed, the sealing gasket 41 is removed from the channel along with the stirring rod 4, so that the water sample can smoothly enter the heating cylinder 13, ensuring that the water sample is mixed before flowing in for heating and evaporation.

[0019] A drain rod 16 is slidably connected to the bottom of the test box 1. The bottom of the test box 1 has a drain channel that communicates with the heating cylinder 13. The drain rod 16 is slidably connected in the channel. The outer wall of the drain rod 16 is wrapped with a waterproof sealing ring. After the test is completed, the drain rod 16 can be pulled to drain the waste liquid in the heating cylinder 13. During the test, the drain rod 16 will remain in the drain channel to seal the drain channel and prevent water sample leakage.

[0020] The top of the cover plate 21 is equipped with a drive chamber 211, and the bottom of the cover plate 21 is rotatably connected to a transmission block 212, which engages with the top of the stirring rod 4. The drive chamber 211 contains a small motor that provides power to the stirring rod 4. The bottom of the cover plate 21 is rotatably connected to the transmission block 212 via a bearing. The top of the transmission block 212 is fixedly connected to the output shaft of the motor in the drive chamber 211 via a coupling. The bottom is provided with a protruding engaging structure. When the operator places the cover plate 21 on top of the mixing cylinder 12, the transmission block 212 can engage with the top of the stirring rod 4. After the motor starts, it drives the stirring rod 4 to rotate through the transmission block 212, thus completing the stirring of the water sample in the mixing cylinder 12. After stirring is completed, the transmission block 212 can be removed by disassembling the cover plate 21, which facilitates the subsequent removal of the stirring rod 4.

[0021] A water inlet 22 is installed at the bottom of the cover plate 2. The water inlet 22 is funnel-shaped, with its top connected to the water collection chamber 32 and its bottom extending directly into the mixing cylinder 12. When in use, the water sample in the three cavities of the water distribution chamber 3 reaches the preset amount and enters the water collection chamber 32. The water sample in the water collection chamber 32 will flow directly into the mixing cylinder 12 through the water inlet 22. The funnel-shaped structure can prevent water sample from splashing out and ensure that the water sample can be added into the mixing cylinder 12 for stirring and mixing.

[0022] Both cover plate 1 (2) and cover plate 21 (21) have positioning blocks 23 installed at their bottoms. The positioning blocks 23 are slidably connected to the inside of the mixing cylinder 12. The positioning blocks 23 are fixedly installed at the bottoms of both cover plate 1 (2) and cover plate 21 (21). The size of the positioning blocks 23 is adapted to the groove opened on the top edge of the mixing cylinder 12. When the operator puts cover plate 1 (2) on top of the mixing cylinder 12, the positioning blocks 23 slide into the groove on the top of the mixing cylinder 12 to achieve precise positioning of cover plate 1 (2). When cover plate 21 is replaced and placed on top of the mixing cylinder 12, the positioning blocks 23 at the bottom of cover plate 21 can also be inserted into the groove to ensure that both covering operations can be accurately aligned with the mixing cylinder 12, avoiding cover plate misalignment that could cause water sample leakage or the transmission block 212 to fail to engage the stirring rod 4.

[0023] The water distribution chamber 3 is equipped with a sealing frame 33, and three drain pipes 34 are installed on one side of the water distribution chamber 3. The sealing frame 33 is a movable plate structure that can slide up and down and has three sealing rings at the bottom. The three sealing rings can cover the bottom openings of the three cavities of the water distribution chamber 3 respectively, so that the staff can smoothly introduce water samples from different positions into the cavities of the water distribution chamber 3. When all three cavities are filled with water, the sealing frame 33 is pushed upward, the bottom opening of the cavity is opened, and the water sample can enter through the opening. Inside the water collection chamber 32, the water sample inside the water collection chamber 32 flows into the mixing cylinder 12 through the water inlet 22. Since the three cavities have the same volume, it can be ensured that the amount of water sample flowing into the mixing cylinder 12 is the same. Three drain pipes 34 are installed on one side of the water distribution chamber 3. The three drain pipes 34 are connected to the three cavities of the water distribution chamber 3 respectively. When water sample is introduced, the excess water sample entering the cavity of the water distribution chamber 3 will be discharged directly through the drain pipes 34, ensuring that the amount of water sample in the three cavities is the same, and further ensuring the uniformity of the mixed water sample.

[0024] The working principle of this utility model is as follows: After water sample collection, the operator first places cover plate 2 on top of the mixing cylinder 12. Cover plate 2 is positioned with the top groove of the mixing cylinder 12 by positioning block 23. Then, water samples to be tested are introduced into the three independent cavities of the water distribution chamber 3. Excess water sample entering the cavities of the water distribution chamber 3 is discharged directly through the drain pipe 34, making the water sample volume in the three cavities consistent. Then, the sealing frame 33 is pulled upward to allow the water samples in the three cavities to enter the water collection chamber 32. The water sample entering the water collection chamber 32 flows into the mixing cylinder 12 through the water inlet 22. Then, the operator can remove cover plate 2 and place cover plate 21 on the mixing cylinder. Above the cylinder 12, the cover plate 21 is positioned by the positioning block 23. At this time, the transmission block 212 is engaged with the top of the stirring rod 4. The motor in the drive chamber 211 is started, which drives the stirring rod 4 to rotate and complete the mixing of the water sample inside the mixing cylinder 12. After the water sample is mixed, the cover plate 21 is removed and the stirring rod 4 is taken out. The mixed water sample enters the heating cylinder 13 through the flow channel of the barrier block 15. The heating element installed inside the heating cylinder 13 heats the water sample inside the heating cylinder 13. The steam generated by the heating of the water sample first enters the mixing cylinder 12, and then enters the detection chamber 14 through the vent hole 111 of the partition plate 11. The gas sensor installed inside the detection chamber 14 completes the odor detection.
