Description

Technical Field

[0001] This utility model relates to the field of pollen bioaerosol sampling technology, and in particular to a pollen aerosol sampling device. Background Technology

[0002] Bioaerosols are aerosols containing biological particles in the air, including microorganisms such as bacteria, fungi, viruses, pollen, and spores, as well as biological macromolecules. They can enter the atmosphere through natural processes such as soil dust and plant release, or through human activities such as wastewater treatment, agricultural production, and laboratory operations, and have multifaceted impacts on the environment, climate, and human health. For example, they may trigger the spread of infectious diseases, allergic reactions, and other health problems, and may also affect the ecological balance.

[0003] Bioaerosols contain bioactive fluorescent substances, such as various amino acids, vitamins, and coenzymes, which are widely present in various microorganisms. Aerosol samplers can use lasers to induce these bioactive substances to produce specific fluorescence spectra, and by analyzing the spectra, aerosols can be detected and identified.

[0004] Traditional sampling devices present numerous inconveniences in terms of the installation and disassembly of aerosol samplers. As sampling work becomes more frequent, the need for sampler maintenance is increasing. The connection between some aerosol samplers and the main body of the device is too fixed, making it difficult and time-consuming to clean, repair, or replace parts of the sampler. Therefore, a pollen aerosol sampling device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pollen aerosol sampling device, which aims to improve the problem of high difficulty and time-consuming operation when cleaning, repairing or replacing parts of the sampler in the prior art.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the pressing plate facilitates user operation, the transmission rod transmits pressing force, and the squeezing block squeezes the conical column to release the square block from the aerosol sampler, allowing for easy disassembly of the aerosol sampler. During installation, after positioning with the cooperation of the guide groove and the locking block, the pressing plate is released, the reset spring pushes the transmission rod to reset, and the conical column, under the action of the strong spring, drives the square block to lock and fix the aerosol sampler, making the installation and disassembly of the aerosol sampler simple and convenient, thereby improving the maintenance efficiency of the entire device.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a pollen aerosol sampling device, including a base 1. A placement opening 2 is provided at the top of the base 1. An aerosol sampler 3 is slidably connected to the inner wall of the placement opening 2. An installation mechanism is slidably connected to the left side of the interior of the base 1, and an adjustment mechanism is rotatably connected to the right side of the interior of the base 1. The base 1 provides support and installation positions for other components and is the basic structure of the entire pollen aerosol sampling device. The placement opening 2 at its top is used to accommodate the aerosol sampler 3. The left side of the interior provides sliding space for the installation mechanism, and the right side provides rotational space for the adjustment mechanism, ensuring the stability of the overall structure of the device. The aerosol sampler 3 is the core component for pollen aerosol sampling and is responsible for collecting pollen aerosol samples during the sampling process.

[0034] The mounting mechanism includes a square block 4, whose outer wall engages with the inner left wall of the aerosol sampler 3. The square block 4 is a key component for fixing the aerosol sampler 3; this engagement ensures that the aerosol sampler 3 will not shake or shift during normal operation, guaranteeing sampling accuracy. A conical column 5 is fixedly connected to the left side of the square block 4, and a rotating plate 6 is rotatably connected to the left side of the conical column 5. A strong spring 7 is fixedly connected to the left side of the rotating plate 6. A chamber 8 is located on the left side of the base 1. The left side of the strong spring 7 is fixedly connected to the inner left wall of the chamber 8. The outer wall of the conical column 5 is slidably connected to the inner wall of the chamber 8, and the outer wall of the rotating plate 6 is slidably connected to the inner wall of the chamber 8. The chamber 8 provides space for the conical column 5, the rotating plate 6, and the strong spring 7, and the rotating plate 6 provides a rotating connection for the conical column 5. This design allows the cone-shaped column 5 to rotate within a certain range. During the installation of the aerosol sampler 3, the compressed spring 7 pushes the cone-shaped column 5 to the right, thereby engaging and fixing the square block 4 with the aerosol sampler 3, ensuring the aerosol sampler 3 is securely installed. A transmission rod 9 is slidably connected to the left side of the base 1. A pressing plate 20 is fixedly connected to the front of the transmission rod 9. The rear side of the pressing plate 20 contacts the front side of the base 1. The pressing plate 20 is the interactive component between the user and the installation mechanism. The user initiates the disassembly of the aerosol sampler 3 by pressing the pressing plate 20. The transmission rod 9 transmits force, transferring the pressing pressure of the pressing plate 20 to the squeezing block 10, thereby moving the squeezing block 10 to squeeze the cone-shaped column 5. The squeezing block 10 is fixedly connected to the rear side of the transmission rod 9, and the outer wall of the squeezing block 10 contacts the outer wall of the cone-shaped column 5. When the cone-shaped column 5 is squeezed by the squeezing block 10, it can move to the left, thereby moving the square block 4 to the left and releasing the pressure on the aerosol sampler 3. The transmission rod 9 is fixedly connected to a movable plate 11. The outer wall of the movable plate 11 is slidably connected to the inner wall of the base 1. The movable plate 11 can transmit the force of the transmission rod 9 to press the return spring 12 and limit the transmission rod 9 to prevent it from falling off. The rear side of the movable plate 11 is fixedly connected to the return spring 12. The rear side of the return spring 12 is fixedly connected to the rear inner wall of the base 1. The return spring 12 uses the pressure generated by its own compression to push the movable plate 11 forward, thereby driving the transmission rod 9 to return to its original position.

[0035] Reference Figure 1 , Figure 2 and Figure 4The adjustment mechanism includes a connecting rod 13, the outer wall of which is slidably connected to the inner right side of the base 1. A knob 14 is fixedly connected to the front of the connecting rod 13, and the rear of the knob 14 contacts the front of the base 1. The knob 14 is the interactive component between the user and the adjustment mechanism. The user inputs the command to adjust the angle of the aerosol sampler 3 by rotating the knob 14, transmitting the rotational force to the connecting rod 13. A worm gear 15 is fixedly connected to the rear of the connecting rod 13. A receiving chamber 16 is opened on the right side of the interior of the base 1. A rotating rod 17 is rotatably connected to the inner wall of the receiving chamber 16. A worm wheel 18 is fixedly connected to the outside of the rotating rod 17. The outside of the worm wheel 18 is meshed with the outside of the worm gear 15. When the connecting rod 13... When the knob 14 is rotated, the worm gear 15 starts to rotate. Because it is meshed with the worm wheel 18, the rotation of the worm gear 15 can drive the worm wheel 18 to rotate, thereby transmitting the rotational force to the worm wheel 18 and initiating the next step of adjusting the angle of the aerosol sampler 3. A locking block 19 is fixedly connected to the left side of the rotating rod 17, and a guide groove is opened on the right side of the aerosol sampler 3. The outer wall of the locking block 19 engages with the inner wall of the guide groove. When the worm wheel 18 rotates, the rotating rod 17 rotates accordingly, thereby driving the locking block 19 to rotate. Because the locking block 19 engages with the guide groove on the aerosol sampler 3, the rotation of the rotating rod 17 can drive the aerosol sampler 3 to rotate, thereby realizing the angle adjustment of the aerosol sampler 3.

[0036] Working principle: When it is necessary to disassemble or assemble the aerosol sampler 3, pressing the pressing plate 20 drives the transmission rod 9 to move backward. This movement of the transmission rod 9 causes the extrusion block 10 to move backward, which in turn extrudes the cone-shaped column 5, causing it to move to the left. This movement of the cone-shaped column 5 to the left causes the square block 4 to move to the left, thus releasing the locking and fixing of the aerosol sampler 3. Therefore, the aerosol sampler 3 can be removed. When installing the aerosol sampler 3, the guide groove and the locking block 19 work together to expel the aerosol sampler. When the aerosol sampler 3 is positioned, after the pressing plate 20 is released, the transmission rod 9 will use the pressure generated by the compression of the return spring 12 and move forward in conjunction with the transmission of the movable plate 11 to reset. At this time, the squeezing block 10 will also move forward to release the squeezing of the cone column 5. The cone column 5, which is no longer squeezed, moves to the right under the action of the strong spring 7 in the compressed state, which in turn drives the square block 4 to move to the right and engage with the aerosol sampler 3, thereby facilitating the installation and disassembly of the aerosol sampler 3 and improving maintenance efficiency.

[0037] Rotating the knob 14 causes the connecting rod 13 to rotate, which in turn causes the worm gear 15 to rotate. Since the worm wheel 18 and the worm gear 15 are meshed, the rotation of the worm gear 15 drives the worm wheel 18 to rotate, which in turn drives the rotating rod 17 to rotate. With the locking block 19 engaging with the guide groove on the aerosol sampler 3, the rotation of the rotating rod 17 drives the locking block 19 to rotate, which in turn drives the aerosol sampler 3 to rotate, thus achieving angle adjustment of the aerosol sampler 3.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
