Description

Technical Field

[0001] This utility model relates to the field of microbial sampling technology, specifically to a spore sampling and analysis instrument. Background Technology

[0002] A spore sampling analyzer is an instrument specifically designed to sample and analyze the content and types of spores (such as mold spores, pollen, and other tiny particles) in the air. The concentration and types of spores can reflect the health of the environment. The presence of mold may indicate high air humidity and a potential risk of mold growth in houses or buildings, while the concentration of pollen reflects seasonal changes and plant growth, which is of great significance for predicting and managing allergy seasons.

[0003] There are many types of existing spore sampling analyzers, but during spore sampling, the diameter of spores is typically between one and several hundred micrometers, and there are significant size differences between different types of spores. For example, a spore sampling analyzer disclosed in utility model patent CN118562593B is designed to sample different types of spores, but its efficiency is low when processing relatively large or small spores. Furthermore, because spores are small and lightweight, especially pollen and some mold spores, they easily drift with the airflow at high velocities, resulting in ineffective capture by the device's filter media. Therefore, existing sampling methods often suffer from insufficient sampling efficiency or missed samples when dealing with spores of different sizes and weights. This indicates that existing technologies urgently need improvement to enhance the capture efficiency and accuracy of spore sampling. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a spore sampling analyzer that effectively solves the problem of low efficiency or inability to sample different types of spores using standard sampling methods in existing technologies.

[0013] Preferably, the outer wall of the L-shaped tube is connected to a return pipe, which penetrates the housing and extends above it. Two second delivery pipes are symmetrically connected to the outer wall of the L-shaped tube between the return pipe and the first solenoid valve. A one-way valve is connected to the upper end of each of the second delivery pipes. A fixed base is fixedly installed on the upper surface of the housing, and an airbag is fixedly installed inside the fixed base. The output end of the one-way valve penetrates the fixed base and communicates with the airbag. The airbag and the return pipe are connected via a connecting pipe, and a fourth solenoid valve is installed inside the connecting pipe. The fourth solenoid valve is electrically connected to the controller.

[0014] Preferably, a linear drive device is fixedly installed on the lower end face of the housing, a U-shaped frame is fixedly installed on the output end of the linear drive device, two connecting rods are symmetrically fixedly installed on opposite sides of the U-shaped frame, two support rods are symmetrically fixedly installed on opposite ends of the two connecting rods, an adhesive plate is fixedly installed on opposite ends of the two support rods, the upper end face of the adhesive plate is coated with adhesive, double-sided tape is pasted on the surface of the adhesive, and a push head is integrally formed on one end of the adhesive plate.

[0015] Preferably, the inner wall of the box has two symmetrically connected exhaust boxes, and the two exhaust boxes are connected to an air inlet box at opposite ends. The air inlet box is slidably connected to the adhesive plate and is connected to the first delivery pipe.

[0016] Preferably, it also includes a replacement component, which includes a vertical plate fixedly installed at the top of the housing, a sliding box fixedly installed on the side of the vertical plate away from the housing, a sliding plate airtightly slidably installed on the inner wall of the sliding box, a second spring fixedly installed between the sliding plate and the sliding box, a straight rod fixedly installed on the lower end face of the sliding plate, a first support frame fixedly installed on the lower end face of the straight rod, a first cylinder rotatably installed in the first support frame, a second support frame fixedly installed on one side of the straight rod, a second cylinder rotatably installed in the second support frame, and double-sided tape wound around the second cylinder;

[0017] The sliding box and the vertical plate have an air vent on one side. A fixed frame is slidably installed on one side of the vertical plate at the position corresponding to the air vent. A plug is fixedly installed inside the fixed frame. The plug is airtightly slidably connected to the air vent. An external frame is fixedly installed at one end of the plug.

[0018] Preferably, a corrugated telescopic tube is fixedly installed on the lower part of the inner wall of the box, a square plate is fixedly installed on one end of the corrugated telescopic tube, an L-shaped top is fixedly installed on the upper surface of the square plate, two third springs are fixedly installed between the square plate and the box, an air supply pipe is connected to one side of the box, the lower end of the air supply pipe passes through the box and connects to the corrugated telescopic tube, and the upper end of the external frame passes through the box and the vertical plate and connects to the sliding box.

[0019] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0020] First, outside air enters the conical barrel through the L-shaped tube and flows out through the air outlet, allowing the air to circulate in the conical barrel. The airflow will cause the ribbon to rub against the mesh plate, generating static electricity, which attracts spores to adhere to the ribbon or mesh plate, thereby accumulating and increasing the total amount of spores collected, and reducing the number of times the equipment needs to be started and the requirements on the equipment.

[0021] By turning on the second fan, outside air is allowed to enter the conical barrel, creating a rotational motion. Larger spores are forced to move towards the wall of the conical barrel due to inertia and centrifugal force and are thrown towards the inner wall. Relatively larger spores are forced to move towards the inner wall due to centrifugal force and then slide down the inner wall of the conical barrel by gravity. Finally, they are discharged into the air intake box for sampling through the second solenoid valve and the first delivery pipe.

[0022] Secondly, for some relatively small spores, which are lightweight and have relatively low inertial force, centrifugal force cannot sufficiently deflect them from the airflow. Therefore, some relatively small spores will flow upward in the conical barrel through the airflow and be driven to the fixed seat, causing the airbag to inflate. By opening the fourth solenoid valve, the inflated airbag will drive the smaller spores to flow into the conical barrel, and then enter the air inlet box through the second solenoid valve and the first delivery pipe. This is used to stick the smaller spores onto the double-sided tape, thus completing the sampling of spores of different sizes.

[0023] Third, the adhesive plate is continuously driven to move by a linear drive device. The adhesive plate first contacts and rolls with the first cylinder, causing the double-sided tape to wrap around the surface of the first cylinder. As the adhesive plate is continuously moved, it contacts the reserve double-sided tape wound on the surface of the second cylinder. The adhesiveness of the double-sided tape and the adhesive will cause the double-sided tape to stick to the upper surface of the adhesive plate, thereby replacing the used double-sided tape and reducing the time spent on manually changing the tape.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Example: Refer to Figures 1 to 9 A spore sampling and analysis instrument, comprising:

[0038] The bracket 1 has a box 2 fixedly installed on its upper end. The top inner end of the box 2 is fixedly installed with a microscopic imaging device 3. The microscopic imaging device 3 is an existing device and is one of the most important components of the spore sampling and analysis instrument. The function of the microscopic imaging device 3 is to magnify and photograph the spores collected by the sampling device, so as to achieve accurate analysis, classification and counting of the spores.

[0039] The primary sampling component 4 includes a conical barrel 402. A mesh plate 403 is fixedly installed on the inner wall of the conical barrel 402. Two connectors 404 are symmetrically installed at the inner top of the conical barrel 402. A ribbon 405 is fixedly installed on the lower end face of the connector 404. A beveled connector 412 is connected to the outer wall of the conical barrel 402. One end of the beveled connector 412 is connected to an air inlet pipe 413. A second fan 414 is fixedly installed inside the air inlet pipe 413. The second fan 414 is electrically connected to a controller. The ribbon 405 and the mesh plate 403 generate static electricity through friction, which adsorbs spores that enter the conical barrel 402. The ribbon 405 and the mesh plate 403 can be made of fiber material and plastic, respectively. Fiber and plastic usually have different electron affinities. Therefore, during friction, electrons are transferred from one material to another, resulting in an imbalance of charges. By turning on the second fan 414, outside air is allowed to enter the conical barrel 402, separating the relatively larger spores and the relatively smaller spores.

[0040] Secondary sampling component 5 is used to sample the air recirculation containing spores;

[0041] Delivery component 6 is used for spore detection.

[0042] Reference Figure 4 An L-shaped pipe 401 is fixedly installed on one side of the housing 2. One end of the L-shaped pipe 401 passes through the housing 2 and extends outward. The lower end of the L-shaped pipe 401 is connected to the conical barrel 402. A first fan 406 is fixedly installed on the inner wall of the L-shaped pipe 401. The first fan 406 is electrically connected to the controller. A first solenoid valve 407 is fixedly installed on the inner wall of the L-shaped pipe 401 and on one side of the first fan 406. The first solenoid valve 407 is installed on one side of the first fan 406. After the first fan 406 draws external air into the L-shaped pipe 401, it flows through the first solenoid valve 407 into the conical barrel 402. The first solenoid valve 407 is electrically connected to the controller. The aforementioned second fan 414 and first fan 406 are existing devices that drive the flow of air or other gases through a rotating impeller, usually driven by an electric motor or other power equipment.

[0043] Reference Figure 3 The lower end face of the conical barrel 402 is connected to a first conveying pipe 408. A second solenoid valve 409 is fixedly installed inside the first conveying pipe 408. The second solenoid valve 409 is electrically connected to the controller. An air outlet pipe 410 is connected to the outer wall of the conical barrel 402 at a lower position. The air outlet pipe 410 passes through the box body 2 and extends. A third solenoid valve 411 is fixedly installed on the inner wall of the air outlet pipe 410. The third solenoid valve 411 is electrically connected to the controller.

[0044] Reference Figures 3 to 4The outer wall of the L-shaped tube 401 is connected to a return pipe 506, which penetrates the housing 2 and extends above it. Two second delivery pipes 501 are symmetrically connected to the outer wall of the L-shaped tube 401 between the return pipe 506 and the first solenoid valve 407. A one-way valve 502 is connected to the upper end of each second delivery pipe 501. A fixing seat 503 is fixedly installed on the upper surface of the housing 2, and an airbag 504 is fixedly installed inside the fixing seat 503. The output end of the one-way valve 502 passes through the fixing seat 503 and… The airbag 504 is connected to the return pipe 506 via a connecting pipe 505. A fourth solenoid valve is installed in the connecting pipe 505. The fourth solenoid valve is electrically connected to the controller. The first solenoid valve 407, the second solenoid valve 409, the third solenoid valve 411 and the fourth solenoid valve are all existing devices, mainly composed of components such as electromagnetic coils, valve bodies and valve seats. When current passes through the electromagnetic coil, the magnetic field generated by the coil causes the valve to move, thereby realizing the on / off control of the fluid.

[0045] Reference Figure 6 A linear drive unit 601 is fixedly installed on the lower end face of the housing 2. A U-shaped frame 602 is fixedly installed on the output end of the linear drive unit 601. Two connecting rods 603 are symmetrically fixedly installed on opposite sides of the U-shaped frame 602. Two support rods 604 are symmetrically fixedly installed on opposite ends of the two connecting rods 603. An adhesive plate 605 is fixedly installed on opposite ends of the two support rods 604. The upper surface of the adhesive plate 605 is coated with adhesive, and double-sided tape is pasted on the surface of the adhesive. One end of the adhesive plate 605... The device is integrally molded with a pusher head 606. The inner wall of the housing 2 is symmetrically connected with two exhaust boxes 607. The two exhaust boxes 607 are connected to an air inlet box 608 at opposite ends. The air inlet box 608 is slidably connected to the adhesive plate 605. The air inlet box 608 is connected to the first conveying pipe 408. When the first conveying pipe 408 conveys air containing spores into the air inlet box 608, the airflow enters the air inlet box 608 vertically. The vertical airflow causes dust to settle downwards, thereby increasing the chance of spores coming into contact with the double-sided tape.

[0046] Reference Figures 7 to 9It also includes a replacement component 7, which includes a vertical plate 701 fixedly installed at the top of the housing 2. A sliding box 702 is fixedly installed on the side of the vertical plate 701 away from 2. A sliding plate 704 is airtightly slidably installed on the inner wall of the sliding box 702. A second spring 714 is fixedly installed between the sliding plate 704 and the sliding box 702. The larger the wire diameter of the second spring 714, the higher its stiffness. Therefore, the air pressure in the sliding box 702 will not push the fixed frame 710 and the plug 711 to move. A straight rod 705 is fixedly installed on the lower end face of the sliding plate 704. A first support frame 706 is fixedly installed on the lower end face of the straight rod 705. A first cylinder 707 is rotatably installed inside the first support frame 706. A second support frame 708 is fixedly installed on one side of the straight rod 705. A second cylinder 709 is rotatably installed inside the second support frame 708. 09 is wrapped with double-sided tape. Air vents are opened on one side of the sliding box 702 and the vertical plate 701. A fixing bracket 710 is slidably installed on one side of the vertical plate 701 at the position corresponding to the air vent. A plug 711 is fixedly installed inside the fixing bracket 710. The plug 711 is airtightly slidably connected to the air vent. An external bracket 713 is fixedly installed at one end of the plug 711. A corrugated telescopic tube 715 is fixedly installed at the lower position of the inner wall of the box 2. A square plate 716 is fixedly installed at one end of the corrugated telescopic tube 715. An L-shaped top head 717 is fixedly installed on the upper surface of the square plate 716. Two third springs 718 are fixedly installed between the square plate 716 and the box 2. An air supply pipe 703 is connected to one side of the box 2. The lower end of the air supply pipe 703 passes through the box 2 and connects to the corrugated telescopic tube 715. The upper end of the external bracket 713 passes through the box 2 and the vertical plate 701 and connects to the sliding box 702.

[0047] The working principle of this utility model is as follows:

[0048] 1. Sampling relatively large spores: The controller operates the first fan 406 and opens the first solenoid valve 407 and the third solenoid valve 411, allowing outside air to enter the conical barrel 402 through the L-shaped pipe 401. The air entering the conical barrel 402 flows out through the air outlet pipe 410. When the air enters the conical barrel 402, the airflow causes the ribbon 405 to swing. The ribbon 405 then rubs against the mesh plate 403, generating static electricity. (During the friction between the ribbon 405 and the mesh plate 403, due to the difference in conductivity, one of them tends to gain electrons while the other loses electrons. Electrons are transferred from one object to another, thus creating an uneven charge.) (by generating static electricity), which attracts spores in the air to adhere to the ribbon 405 or the mesh plate 403. It should be noted that in the existing technology, air samples are automatically collected every hour or every few hours during the spore sampling process. The sampling time interval can be adjusted according to the research needs. By using the electrostatic collection method described above, spores carried in the air within a certain period of time can be collected into the conical barrel 402. The collected spores have different sizes. Compared with single rapid filtration, this cumulative collection can increase the total amount of spores collected and reduce the number of times the equipment is started and the requirements on the equipment. For example, the collection device does not need to run at all times, reducing the real-time load on the equipment.

[0049] The controller opens the second fan 414 and the second solenoid valve 409, and closes the third solenoid valve 411 and the first solenoid valve 407. The second fan 414 discharges outside air into the conical barrel 402 through the air inlet pipe 413 and the inclined joint 412. The air entering the conical barrel 402 through the inclined joint 412 (the inclined joint 412 has a certain inclination angle, the inclination angle is about 30° to 45°) will cause rotational motion in the conical barrel 402. The airflow will rotate along the inner wall of the conical barrel 402. Due to inertia and centrifugal force, the spores are forced to move towards the wall of the conical barrel 402. The relatively large spores are forced to move towards the inner wall of the conical barrel 402 by centrifugal force. Then, the spores slide down the inner wall of the conical barrel 402 under the action of gravity, and finally are discharged into the air inlet box 608 through the second solenoid valve 409 and the first delivery pipe 408.

[0050] 2. Replacing the tape: The spores entering the air intake box 608 come into contact with the double-sided tape and adhere to it. Then, spore-free air flows out through the exhaust box 607. The controller shuts off the second fan 414 and turns on the linear drive device 601. The linear drive device 601 drives the U-shaped frame 602, connecting rod 603, and support rod 604 to move. The support rod 604 moves the adhesive plate 605 along with the frame. The frame stops when it reaches below the microscope imaging device 3, where the microscope imaging device 3 takes pictures. After the pictures are taken, the linear drive device 601 continuously drives the adhesive plate 605 to move. As the adhesive plate 605 moves, it causes the pusher head 606 to contact the square plate 716 and compress the third spring 71. 8. The air inside the corrugated telescopic tube 715 is compressed and enters the sliding box 702 through the air supply pipe 703, increasing the air pressure inside the sliding box 702. The increased air pressure pushes the slide plate 704 to slide and descend within the sliding box 702, stretching the second spring 714. The descending sliding box 702 will drive the straight rod 705, the first support frame 706, the first cylinder 707, the second support frame 708, and the second cylinder 709 to descend together. When the first cylinder 707 descends, it will approach and contact the moving adhesive plate 605 with the double-sided tape. After contact with the double-sided tape, the double-sided tape will stick to the surface of the first cylinder 707. The first cylinder 707 will then... The double-sided tape is rolled around the surface of the first cylinder 707 upon contact, and the discarded double-sided tape wrapped around the surface of the first cylinder 707 can be collected and processed later. Only adhesive remains on the surface of the adhesive plate 605. As the adhesive plate 605 is continuously driven to move, it approaches the second cylinder 709 and comes into contact with the double-sided tape wound on the surface of the second cylinder 709. When the double-sided tape comes into contact with the adhesive plate 605, the adhesive properties of the tape and the adhesive cause the tape to stick to the upper surface of the adhesive plate 605. (Since the double-sided tape has adhesive on both sides, it can be wound in sections during the storage and use process on the surface of the second cylinder 709.) Furthermore, the two ends of the double-sided tape are not coated with glue on either side, so that each section of double-sided tape is not completely adhered together. The two ends of the double-sided tape without glue are first adhered to the glued surface of the adhesive plate 605. Subsequently, the square plate 716, which is continuously squeezed and moved, will cause the top head 717 to contact the outer frame 713, causing the outer frame 713, the plug head 711, and the fixing frame 710 to move and stretch the first spring 712. The plug head 711 will disengage from the vent, and the air in the sliding box 702 will flow out through the vent. The stretched second spring 714 will cause the slide plate 704, the straight rod 705, the first support frame 706, the first cylinder 707, the second support frame 708, and the second cylinder 709 to rise.The controller will then drive the adhesive plate 605 to move in the opposite direction back into the intake box 608 for the next sampling.

[0051] 3. Sampling of relatively small spores: During the process of the second fan 414 supplying air to the conical barrel 402 to separate the spores from the air and transport them into the air inlet box 608, some relatively small spores are lightweight and have relatively low inertia. Centrifugal force cannot sufficiently deflect them from the airflow, so they easily move with the airflow without sufficient force to force them to settle. Therefore, some relatively small spores will flow upwards in the conical barrel 402 through the airflow, enter the L-shaped pipe 401, and then enter the airbag 504 through the second delivery pipe 501 and the one-way valve 502. During the continuous transport process, the airbag 504... In the expansion process described above, after the first sampling of relatively large spores is completed and the tape is replaced, the controller opens the fourth solenoid valve. The expanded airbag 504 causes the air containing relatively small spores in the fixing seat 503 to be transported into the connecting pipe 505 and the return pipe 506 (the pressurized air transported by the airbag 504 when it expands is greater than the air pressure transported by the first fan 406), and enters the conical barrel 402. It then enters the air inlet box 608 through the second solenoid valve 409 and the first delivery pipe 408, thereby sticking the relatively small spores onto the double-sided tape, completing the sampling of spores of different sizes.

[0052] In summary, within a certain time frame, static electricity is generated between the ribbon 405 and the mesh 403 in flowing air, causing relatively large spores and relatively small spores to adhere to the ribbon 405 or the mesh 403. During spore capture, external air is introduced into the conical container 402, separating spores of different sizes. Larger spores are collected, and then the double-sided tape is replaced to collect smaller spores. This allows for the separation of spores of different sizes based on their mass and aerodynamic characteristics. Larger spores, due to their greater mass, are more easily carried to the collection area by the airflow, while smaller spores may remain in the airflow and be transported into the airbag 504, thus achieving effective grading and a highly efficient and precise spore separation and collection process.

[0053] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
