Abstract
Description
Technical Field
[0001] This utility model relates to the field of plant vigor monitoring technology, and in particular to a pretreatment device for plant vigor monitoring equipment. Background Technology
[0002] Plant essence refers to the gaseous organic compounds naturally released by plant organs (such as leaves, flowers, and roots), whose main components include terpenes, organic acids, and esters. These gaseous organic compounds can purify the air and also play a role in regulating the human nervous system and enhancing immunity. Plant essence monitoring refers to the quantitative analysis of the content of volatile organic compounds within a unit space of plants to assess the release level of plant essence. Currently, existing technology mainly relies on long-term monitoring using laboratory gas chromatography-mass spectrometry (GC-MS). However, in practical applications, because plants are usually distributed in outdoor environments with large diurnal temperature and humidity variations, a large amount of moisture is easily mixed in when collecting gaseous organic compounds. If samples containing moisture are directly sent into the GC-MS, it can easily damage the sensor, increasing the cost of equipment maintenance and replacement, and potentially affecting the accuracy and reliability of the monitoring results.

[0044] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0045] like Figure 1-11 As shown, the pretreatment device for plant vital signs monitoring equipment includes a dehumidification mechanism 6, which includes an air intake unit, a first dehumidification unit, a second dehumidification unit and an exhaust unit connected in sequence.
[0046] The intake unit includes a retractable sampling tube 615;
[0047] The first dehumidification unit includes a first dehumidification housing 61, the air inlet of the first dehumidification housing 61 is connected to the bottom end of the sampling tube 615, a detachable first dehumidification component 63 is provided inside the first dehumidification housing 61, and a drain outlet 62 is provided at the bottom end of the first dehumidification housing 61.
[0048] The second dehumidification unit includes a second dehumidification housing 65, the air inlet of the second dehumidification housing 65 is connected to the air outlet of the first dehumidification housing 61, and a detachable second dehumidification component 611 is provided inside the second dehumidification housing 65.
[0049] The exhaust unit includes an exhaust pipe body 69, the air inlet of the exhaust pipe body 69 is connected to the air outlet of the second dehumidification housing 65, an exhaust drive device 610 is provided inside the exhaust pipe body 69, and a humidity sensor assembly 613 is also provided at the input end of the exhaust pipe body 69.
[0050] In this embodiment, the sampling tube 615 can be a corrugated pipe. To maintain the shape of the sampling tube 615, a foldable metal material can also be installed on the tube wall. The exhaust drive device 610 can be a vacuum pump, exhaust fan, etc. The first dehumidification component 63 can include a filter section and a dehumidification section connected to the bottom of the filter section. The filter section can be any one of glass fiber, PE, or ceramic, and it can filter some pollen and dust. The dehumidification section uses a desiccant, which is mainly used for dehumidification. The second dehumidification component 611 uses a desiccant. The desiccant can be selected according to the monitoring category, for example... Molecular sieves, Nafion membranes, etc. The output end of the exhaust pipe 69 is connected to the inlet end of a monitoring device (e.g., a laboratory gas chromatograph-mass spectrometer).
[0051] In application, the sampling tube 615 is first pulled to the area to be monitored. The retractable sampling tube 615 is used to meet the specific height and angle requirements of the plant area, aiming to obtain more accurate monitoring samples. Then, the exhaust drive device 610 is activated, drawing gas from the plant area to be monitored into the sampling tube 615. This gas passes sequentially through the first dehumidification component 63 and the second dehumidification component 611, allowing for sufficient moisture adsorption. Finally, the dried gas is discharged from the exhaust pipe 69 for accurate moisture content detection. If water marks are found at the drain outlet 62, it indicates that the filter element of the first dehumidification component 63 is saturated, requiring replacement. If the humidity sensor component 613 detects that the gas flowing into the exhaust pipe 69 contains substandard moisture, the second dehumidification component 611 needs to be replaced.
[0052] Preferably, an air inlet frame 616 is connected to the top end of the sampling tube 615;
[0053] A cover 64 is hinged to the air intake frame 616. When the cover 64 covers the air intake frame 616, an air intake 618 is formed between the cover 64 and the air intake frame 616.
[0054] In this embodiment, on rainy days, the protective cover 64 can be closed to shield and protect the sampling tube 615 from rainwater entering the sampling tube 615; if it is not raining, the protective cover 64 can be opened to facilitate the absorption of more gas.

[0057] The first dehumidification component 63 is located inside the first storage frame 619.
[0058] In this embodiment, the first storage frame 619 is adapted to the inner wall of the first dehumidification housing 61. When the first dehumidification component 63 needs to be replaced, the first door panel 620 is pulled outward to move the first storage frame 619 out completely, and the first dehumidification component 63 is replaced. Then the first storage frame 619 is slid into the first dehumidification housing 61 until the first door panel 620 closes the first opening.
[0059] The first air inlet of the first storage frame 619 can be fully open, facilitating the placement of the first dehumidification component 63. The first air inlet at the bottom of the first storage frame 619 can be smaller than the area of the bottom of the first storage frame 619. Figure 4 As shown, this allows for the support of the first dehumidification component 63. The first protective grid 621 positions the first dehumidification component 63 in the first storage frame 619, preventing accidental displacement during gas flow. Figure 4 As shown, in order to support the first dehumidification component 63, the first protective grille 621 at the bottom can be provided with a grille extension section 629 that is inserted into the first flow port. In addition, the first protective grille 621 at the air inlet end of the storage frame 619 can prevent impurities from entering the first dehumidification component 63.
[0060] To facilitate the replacement of the second dehumidification component 611, preferably, the top of the second dehumidification housing 65 is provided with a second opening, and a second storage frame 612 is slidably provided inside the second dehumidification housing 65. The top of the second storage frame 612 is connected to a second door panel 66 for closing the second opening, and the air inlet and outlet of the second storage frame 612 are both provided with second flow ports.

[0063] In this embodiment, the second storage frame 612 is adapted to the inner wall of the second dehumidification housing 65. When the second dehumidification component 611 needs to be replaced, the second door panel 66 is pulled upward to move the second storage frame 612 out completely, and the second dehumidification component 611 is replaced. Then the second storage frame 612 is slid into the second dehumidification housing 65 until the second door panel 66 closes the second opening.
[0064] The second storage frame 612 has second flow ports at both its air inlet and outlet, both of which can be fully open to facilitate the flow of sample gas. The second protective grid 614 can position the second dehumidification component 611 of the second storage frame 612 to prevent it from accidentally shifting during gas flow.
[0065] Preferably, both the first door panel 620 and the second door panel 66 are provided with ear blocks 67.
[0066] In this embodiment, the ear block 67 is provided to facilitate pulling the first door panel 620 and the second door panel 66.
[0067] Preferably, the inner cavity of the first dehumidifying housing 61 is provided with an inclined cavity wall below the first protective grid 621, and the inclined cavity wall has a gradually increasing depth toward the drain outlet 62.
[0068] In this embodiment, the inclined cavity wall facilitates the rapid flow of excess water on the first dehumidification component 63 to the drain outlet 62, allowing staff to check the working status of the first dehumidification component 63.
[0069] Preferably, the air inlet of the first dehumidifying housing 61 is located at its top end, and the air outlet of the first dehumidifying housing 61 is located at the bottom end of its side wall.

[0071] The top of the exhaust pipe body 69 is connected to the air outlet of the second dehumidification housing 65 via a connecting shell 68.
[0072] In this embodiment, the staggered arrangement of the air inlet and outlet of the first dehumidification housing 61 extends the travel path of the sample gas, ensuring that the sample gas receives sufficient initial dehumidification. Similarly, the staggered arrangement of the air inlet and outlet of the second dehumidification housing 65 extends the travel path of the sample gas, ensuring that the sample gas receives sufficient secondary dehumidification. The connecting housing 68 provides a sealing effect, preventing leakage of the sample gas during exhaust and concentrating the sample gas within the operating range of the humidity sensor assembly 613 to obtain accurate humidity data.
[0073] To facilitate the installation of the humidity sensor assembly 613, preferably, a bracket 622 is provided inside the exhaust pipe body 69, and the humidity sensor assembly 613 is mounted on the bracket 622.

[0076] The bottom of the housing 1 is equipped with retractable support legs 2.
[0077] In this embodiment, support legs 2 should be provided at all four corners of the bottom of the housing 1, so that the height of the support legs 2 can be adjusted according to the terrain to maintain the levelness of the housing 1. The partition 5 can prevent the liquid discharged from the drain outlet 62 in the dehumidification mechanism 6 from seeping into other areas of the housing 1; the slit 3 can facilitate ventilation.
