Description

Technical Field

[0001] This utility model relates to the field of plant pathogen detection technology, specifically to a filtration system structure for a spore capture device. Background Technology

[0002] In the field of plant pathogen detection, accurately collecting airborne plant pathogen spores is a crucial prerequisite for subsequent pathogen analysis, prediction, and control. However, current spore-capturing devices on the market have significant shortcomings in spore collection, and the inability to collect spores has become a pressing issue that the industry urgently needs to address. The tiny size of spores and their dispersed distribution in the air, coupled with the presence of numerous other impurities, greatly increase the difficulty of accurate spore collection.

[0003] Because spores are tiny (usually between 1-100 μm in diameter) and dispersed in the air, and because the air also contains a large number of impurities such as leaf fragments, insects, dust, and pollen, existing equipment is inefficient and produces inaccurate results, which seriously affects the detection and control of plant pathogens. Therefore, developing a device that can efficiently and accurately collect plant pathogen spores is of great practical significance. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a filtration system structure for spore capture equipment to solve the above problems.

[0005] The purpose of this utility model is achieved as follows: a filtration system structure for a spore-capturing device includes a housing, an air inlet hopper at the upper end of the housing, and an upper filter structure assembly and a lower filter structure assembly respectively at the upper and lower ends inside the air inlet hopper. The upper filter structure assembly is used to initially filter out larger impurities in the air, and the lower filter structure assembly is used to further filter out other small impurities in the air.

[0006] Preferably, the upper filter structure assembly is provided with a rainproof cover at its upper end.

[0007] Preferably, the upper filter structure component includes a first-stage filter, with an upper baffle ring and a lower baffle ring at its upper and lower ends, respectively, and the first-stage filter is fixedly installed on a fixed column by the upper baffle ring and the lower baffle ring.

[0008] Preferably, the first-stage filter screen is a diamond mesh with a pore size of 1mm.

[0009] Preferably, the upper filter structure assembly includes a second-stage filter and a platform insert plate. The second-stage filter is installed on the platform insert plate, and the lower end of the air inlet hopper is provided with a secondary filter docking channel, which is inserted into the platform slot at the upper end of the platform insert plate.

[0010] Preferably, the second-stage filter is a nylon filter with a pore size of 50μm or 100μm.

[0011] Preferably, the lower end of the platform insert plate is connected to a negative pressure source via a negative pressure duct to provide power for airflow by forming a negative pressure airflow.

[0012] This utility model has the following beneficial effects:

[0013] 1. This spore-capturing device uses a filtration system structure. Air enters through the air inlet hopper and first passes through the upper filter structure to filter out larger impurities (such as leaf fragments, insects, etc.). Then, it passes through the lower filter structure to filter out tiny impurities (such as dust, pollen, etc.). Finally, the air carrying spores enters the subsequent collection system. Through the synergistic effect of the two-stage filters, the smooth passage and collection of spores in the air is ensured, while the interference of impurities on the spore collection process is minimized, thereby improving the purity and quality of the collected spores.

[0014] 2. The upper part of the filter structure component is equipped with a rain cover to prevent rainwater from entering the equipment, avoid the filter from growing mold due to dampness or affecting air circulation, and extend the service life of the equipment. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0022] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0023] Example 1:

[0024] A filtration system structure for a spore-capturing device includes a housing 1. An air inlet 3 is provided at the upper end of the housing 1. An upper filter structure assembly 4 and a lower filter structure assembly 5 are respectively provided at the upper and lower ends inside the air inlet 3. The upper filter structure assembly 4 is used to initially filter out larger impurities in the air, and the lower filter structure assembly 5 is used to further filter other small impurities in the air.

[0025] When using this device, air enters through the air inlet 3, first passing through the upper filter structure component 4 to filter out larger impurities (such as leaf fragments, insects, etc.), and then passing through the lower filter structure component 5 to filter out tiny impurities (such as dust, pollen, etc.). Finally, the air carrying spores enters the subsequent collection system. Through the synergistic effect of the two-stage filters, the smooth passage and collection of spores in the air is ensured, while the interference of impurities on the spore collection process is minimized, thereby improving the purity and quality of the collected spores.

[0026] In this embodiment, the upper end of the upper filter structure component 4 is provided with a rain cover 2 to prevent rainwater from entering the equipment, avoid the filter from growing mold due to dampness or affecting air circulation, and extend the service life of the equipment.

[0027] In this embodiment, the upper filter structure component 4 includes a first-stage filter 41, which is a diamond mesh with a pore size of 1mm. The first-stage filter 41 has an upper retaining ring 42 and a lower retaining ring 43 at its upper and lower ends, respectively. The first-stage filter 41 is fixedly mounted on a fixed column 44 via the upper and lower retaining rings 42 and 43. When air flows through the first-stage filter 41, impurities larger than 1mm in diameter (such as insects and leaf debris) are intercepted by the diamond mesh, while air and smaller particles (including spores) pass through the mesh and enter the next stage of filtration. The diamond mesh is fixed by the retaining rings and the column, ensuring structural stability and preventing filter movement from affecting the filtration effect.

[0028] In this embodiment, the upper filter structure component 4 includes a second-stage filter 51 and a platform insert plate 52. The second-stage filter 51 is installed on the platform insert plate 52. The lower end of the air inlet hopper 3 is provided with a secondary filter docking channel 54. The secondary filter docking channel 54 is inserted into the platform slot 53 at the upper end of the platform insert plate 52. The second-stage filter 51 is a nylon filter with a pore size of 50μm or 100μm. The fine pore size (50-100μm) of the nylon filter can intercept tiny impurities in the air, and the plug-in structure makes filter replacement more convenient and reduces equipment maintenance costs.

[0029] In this embodiment, the lower end of the platform insert plate 52 is connected to a negative pressure source through a negative pressure duct 6 to provide the power for air flow by forming a negative pressure airflow. The negative pressure source forms an airflow suction force through the negative pressure duct 6, causing air to flow in from the air inlet hopper 3.

[0030] The working principle of this utility model is as follows: The spore-capturing device uses a filtration system structure, including a shell 1. An air inlet 3 is located at the upper end of the shell 1. An upper filter assembly 4 and a lower filter assembly 5 are respectively located at the upper and lower ends inside the air inlet 3. The upper filter assembly 4 is used to initially filter out larger impurities in the air, while the lower filter assembly 5 is used to further filter out other minute impurities in the air. When using this device, air enters through the air inlet 3, first passing through the upper filter assembly 4 to filter out larger impurities (such as leaf fragments, insects, etc.), and then passing through the lower filter assembly 5 to filter out minute impurities (such as dust, pollen, etc.). Finally, the air carrying spores enters the subsequent collection system. Through the synergistic effect of the two-stage filters, the smooth passage and collection of spores in the air is ensured, while minimizing the interference of impurities on the spore collection process, thus improving the purity and quality of the collected spores.

[0031] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
