[0002] Airborne allergenic pollen is an important outdoor allergen, with a diameter of about 10 to 100 microns, which can induce a variety of allergic diseases such as allergic rhinitis, allergic conjunctivitis, allergic asthma, and allergic dermatitis. The incidence of pollen-induced allergic diseases shows strong consistency with the pollen peak period. The severity of pollen allergy symptoms depends on the number of pollen and the time of exposure. Seasonal allergic rhinitis caused by spring tree pollen and autumn grass pollen is very serious.

[0003] Pollen allergy not only directly damages the physiological function of patients, but also seriously affects the quality of life, causes a series of problems such as low learning and working efficiency, missed work, and increased economic burden, and then causes psychological problems such as anxiety and depression, which seriously endangers human health. Pollen monitoring is currently the most reliable and feasible method internationally recognized for assessing the health hazards of pollen-allergic patients.

[0004] Currently, in terms of pollen collection, the mainstream approach is still to place clean slides on specially designed collection devices, and to arrange them in places with strong air flow in order to allow pollen in the air to naturally deposit on their surfaces.

For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0046] The following will be described in detail in combination with the accompanying drawings Figures 1-7 Further detailed description of the present application, the present application embodiment discloses an air allergen sampling device.

[0047] Referring to Figure 1 and Figure 2 As shown in the drawings, an air allergen sampling device comprises a box body 100, a rotating mechanism 300, an adhesive coating mechanism 200 and a driving mechanism 400. An inner cavity with an open top is provided inside for accommodating the main components. The box body 100 is provided with a cover plate 120 which can be opened and closed at the top, which can tightly cover the opening of the inner cavity when the cover plate 120 is closed, preventing external interference. The top surface of the cover plate 120 is provided with a collection port 160 for air samples, and a flip cover port 130 is provided on the side of the cover plate 120 opposite the collection port 160. A flip cover 140 is hinged at the flip cover port 130, and the flip cover 140 can be used to install small equipment on the rotating mechanism 300 without opening the cover plate 120.

[0048] Referring to Figure 3 and Figure 4As shown, the rotating mechanism 300 is arranged inside the box body 100, and the rotating mechanism 300 is provided with a rotating disc 180, which is arranged horizontally and provided with a plurality of collection boxes 500 sliding along the radial direction of the rotating disc 180, and the plurality of collection boxes 500 are arranged along the circumferential direction of the rotating disc 180. Through the rotating movement of the rotating mechanism 300, each collection box 500 can reach the predetermined collection port 160 in turn for air allergen sampling.

[0049] Referring to Figure 4 and Figure 5 As shown, the adhesive coating mechanism 200 is fixedly arranged on the cover plate 120 and corresponds to the position of the collection port 160. When the slide needs to be exposed outside through the collection port 160, the adhesive coating mechanism 200 performs instant adhesive coating treatment on it. In order to ensure that the adhesive remains wet during use, it effectively avoids the drying of the adhesive due to the advance application of the adhesive, and the falling of the collected air sample on the adhesive before the collection time, thereby ensuring the quality of the air allergen sampling.

[0050] The driving mechanism 400 is also fixed on the cover plate 120 and is responsible for pushing the collection box 500 to move horizontally along the radial direction of the rotating disc 180. When air allergen sampling is needed, the driving mechanism 400 will push the designated collection box 500 to the position below the collection port 160, so as to receive the air sample entering from the collection port 160.

[0051] The controller 110 is connected to the rotating mechanism 300, the adhesive coating mechanism 200 and the driving mechanism 400 through electrical signals. The controller 110 can accurately control the actions of the above mechanisms according to the preset program or external instructions, including the rotation angle of the rotating disc 180, the timing of the adhesive coating and the in-out speed of the collection box 500, etc., so as to realize the automatic air allergen sampling process, and further improve the intelligent level and operation convenience of the device.

[0052] The rotating mechanism 300 is used to realize precise rotation control, which comprises a servo motor 310, a base 320 and a rotating ring 330. The base 320 is fixedly connected to the bottom of the top surface of the box body 100 to serve as the basic support of the entire rotating mechanism 300, thereby ensuring the stability of the rotating mechanism 300 during operation. Secondly, the rotating ring 330 passes through the middle line of the base 320 and the inner cavity opening of the box body 100, with one end extending outward from the top of the box body 100 and the other end being arranged inside the box body 100 and provided with a gear. The servo motor 310 is fixedly installed on the base 320, and the driving end thereof is engaged with the gear on the rotating ring 330, so as to realize the transmission of the driving torque output by the motor to the rotating ring 330. The rotating ring 330 is coaxially fixedly connected to the rotating disc 180 arranged at the outer end of the box body 100, so that when the rotating ring 330 rotates, the rotating disc 180 can be directly driven to rotate synchronously, thereby ensuring the motion consistency between the rotating ring 330 and the rotating disc 180.

[0053] In addition, the servo motor 310 and the controller 110 are electrically connected to each other. The controller 110 precisely controls the rotation angle and speed of the servo motor 310, and then precisely controls the position change of the rotating disc 180. Such precise control not only improves the response speed and positioning accuracy of the system, but also improves the working efficiency and reliability of the entire device.

[0054] The rotating disc 180 is uniformly provided with eight slide grooves 190, which extend along the radial direction of the rotating disc 180, i.e., are arranged in a radial pattern from the center. Two parallel slide rails 191 are arranged on the side wall of each slide groove 190, and the two slide rails 191 are closely matched to provide stable support and guiding effect for the collection box 500 placed thereon.

[0055] Referring to FIGS. 1, 2 and 3, Figure 6 and Figure 7 The collection box 500 comprises a box bottom 510 for accommodating the glass slide and a box cover 520 for covering the box bottom 510 to seal the glass slide and protect the internal glass slide from being contaminated or damaged. Two sides of the box bottom 510 are provided with track grooves 511 corresponding to the slide rails 191. When the collection box 500 is installed, the box bottom 510 is only needed to be aligned with the slide groove 190, the two slide rails 191 in the slide groove 190 are aligned with the track grooves 511 on the box bottom 510 and are inserted, so that the horizontal stable sliding of the collection box 500 in the slide groove 190 can be easily realized. In this way, it is ensured that the collection box 500 can smoothly slide in the slide groove 190 without tilting or shaking.

[0056] The sliding direction of the collection box 500 is the length direction of the collection box 500, which helps to ensure that the slide can smoothly slide together with the collection box 500 in the sliding groove 190 on the turntable 180. The bottom 510 of the collection box 500 is provided with an accommodation groove 512 with an opening at the top, which is specially designed in size and shape to accommodate the slide, and the width of the slide is tightly attached to the two side walls of the accommodation groove 512, thereby providing the necessary stability during installation and use, preventing the slide from shifting or falling off, and especially avoiding the risk of the slide being lost or damaged in the traditional collection device in windy weather.

[0057] And there is a certain gap between the side wall in the length direction of the slide and the accommodation groove 512, mainly to facilitate the user to easily disassemble or replace the slide when needed. It not only ensures the simplicity of operation, but also does not affect the firmness of the slide in use.

[0058] The length of the bottom 510 of the collection box 500 is provided with two dovetail grooves 530 with openings upward, and the two dovetail grooves 530 penetrate the entire length of the bottom 510 of the collection box 500. Correspondingly, on the side of the cover 520 facing the bottom 510, two dovetail strips 540 matched with the dovetail grooves 530 are arranged, which are fixedly connected to the bottom of the cover 520. During installation, the bottom 510 of the collection box 500 can be pushed along the width direction to align the dovetail strips 540 with the dovetail grooves 530 and smoothly insert, so as to realize the close connection between the cover 520 and the bottom 510 of the collection box 500, and form a completely sealed state. This way is not only simple and easy to operate, but also effectively avoids the possibility of external pollutants entering the inside of the collection box 500, ensuring the safety and cleanliness of the inside slide.

[0059] The cover 520 is provided with a stepped block 550 protruding upward in the width direction, and the stepped block 550 is higher than the bottom surface of the cover 520 and gradually protrudes outward near the center of the cover 520. The bottom 510 of the collection box 500 is also provided with a stepped groove 560 corresponding to it in the width direction, which is formed by the inward recess of the outer surface of the bottom 510 of the collection box 500. When the collection box 500 is correctly installed on the turntable 180, the end with the stepped groove 560 and the stepped block 550 should point to the center position of the turntable 180, that is, this end is closer to the center of the turntable 180 than the other end of the collection box 500

[0060] When it is necessary to open the collection box 500 for maintenance or replacement of the glass slide, the box bottom 510 is pushed by the driving device to move along the slide rail 191 in a direction away from the center of the turntable 180. In this process, the stepped block 550 will be separated from the stepped groove 560, especially the part near the center of the box cover 520 will first be out of contact, so as to avoid the interference between the stepped block 550 and the stepped groove 560 during sliding, and ensure that the box bottom 510 can be smoothly slid out, facilitating the subsequent operation of the user.

[0061] A first inclined block 570 and a second inclined block 580 are also arranged in the width direction of the collection box 500. The first inclined block 570 is fixedly connected to the width end face of the box bottom 510, located on the side opposite to the stepped groove 560, and the inclination angle thereof gradually increases from one end close to the accommodation groove 512 to the other end. The second inclined block 580 is fixed to the bottom face of the box cover 520, and the inclination angle thereof gradually decreases from one end close to the center of the box cover 520 to the end of the box cover 520. When the box cover 520 is closed with the box bottom 510, the inclined faces 150 of the first inclined block 570 and the second inclined block 580 will tightly fit together.

[0062] In this way, the paths of the particles in the air entering the collection box 500 from the side wall in the length direction of the collection box 500 are increased through the cooperation between the dovetail groove 530 and the dovetail strip 540, the stepped groove 560 and the stepped block 550, and the first inclined block 570 and the second inclined block 580, effectively preventing external substances from entering the inside of the collection box 500, and ensuring the cleanliness of the glass slide inside the collection box 500.

[0063] One end of the cover plate 120 is provided with an inclined face 150, and the inclined face 150 is lower than the top face of the cover plate 120 towards the west side of the cover plate 120, that is, the inclined face 150 is gradually inclined and lowered from one side of the cover plate 120 to the edge end of the cover plate 120. The collection port 160 is arranged at the inclined face 150 and is arranged vertically through the inclined face 150.

[0064] When collecting the air sample, the turntable 180 is rotated under the drive of the servo motor 310, and the collection box 500 on the turntable 180 is located below the collection port 160 and is closer to the center of the turntable 180 in the radial direction of the turntable 180. At this time, the driving mechanism 400 pushes the box bottom 510 carrying the glass slide to slide out along the slide rail 191, and is pushed out from the collection port 160, so as to collect the side wall of the air sample.

[0065] By setting the collection port 160 at the inclined surface 150, the influence of the cover plate 120 on the air sample collection of the slide can be reduced, making the operation more smooth. By pushing the slide placing box bottom 510 out of the collection port 160, the obstruction of the cover plate 120 to the collection of the slide during the air sample collection can be reduced.

[0066] The driving mechanism 400 includes an electromagnetic slide rod 410 and an electromagnetic slide block 420. The electromagnetic slide rod 410 is fixedly connected to the inner side of the inclined surface 150 of the cover plate 120, and the length extension direction of the electromagnetic slide rod 410 is arranged along the radial direction of the turntable 180, and the length extension direction of the electromagnetic slide rod 410 is in the same radial direction of the turntable 180 as the collection port 160. The electromagnetic slide block 420 is slidably arranged along the length direction of the electromagnetic slide rod 410. The electromagnetic slide block 420 is provided with a connecting assembly for connecting the collection box 500. The electromagnetic slide rod 410 is electrically connected with the controller 110, so that the controller 110 controls the movement of the electromagnetic slide block 420 on the electromagnetic slide rod 410.

[0067] The connecting assembly includes a connecting rod 430 and a magnetic plate 440. One end of the connecting rod 430 is fixedly connected to the electromagnetic slide block 420, and the other end is fixedly connected with the magnetic plate 440. The length extension direction of the connecting rod 430 is perpendicular to the length extension direction of the electromagnetic slide rod 410. The side wall of the bottom of each collection box 500 towards the center of the turntable 180 is provided with an iron sheet, which makes the magnetic plate 440 can attract and push the box bottom 510 to move, ensuring the accuracy and reliability of the operation process.

[0068] When air sample collection is needed, the servo motor 310 drives the turntable 180 to rotate, so that the specified collection box 500 moves to the position below the collection port 160, and then the servo motor 310 stops running. This precise positioning technology ensures that each collection can be carried out at the correct position, improving the efficiency and success rate of sample collection. Subsequently, under the instruction of the controller 110, the electromagnetic slide block 420 drives the connecting rod 430 and the magnetic plate 440 installed thereon to approach the bottom of the collection box 500. When the magnetic plate 440 contacts the box bottom 510, it will form a magnetic attraction with the iron sheet on the box bottom 510. Then, the electromagnetic slide block 420 continues to slide along the electromagnetic slide rod 410 and pushes the box bottom 510 to move outward along the slide rail 191, thereby realizing the action of pushing the slide out of the collection port 160.

[0069] When the box bottom 510 needs to be reset, the electromagnetic slide block 420 moves along the electromagnetic slide rod 410 towards the center of the turntable 180, and the magnetic attraction between the magnetic plate 440 and the iron sheet is used to pull the box bottom 510 to move towards the center of the turntable 180, completing the reset operation.

[0070] When the box bottom 510 is reset, the electromagnetic slider 420 continues to move towards the center of the rotating disc 180, overcoming the magnetic attraction between the magnetic plate 440 and the iron sheet, and finally separates from the collection box 500 that has completed the air allergen sampling. This separation process ensures that the next sample collection step can start smoothly, further optimizing the overall operation process.

[0071] After the separation is completed, the electromagnetic slider 420 stops sliding, and the servo motor 310 is started again to drive the rotating disc 180 to rotate to replace the next collection box 500. After replacement, the electromagnetic slider 420 repeats the above push-out and reset actions to perform the next air sample collection work on the glass slide. Through the coordinated operation of the servo motor 310 and the electromagnetic slider 420, rapid and accurate sample collection and replacement are achieved, significantly improving the working efficiency and reliability of the equipment.

[0072] By presetting the time interval for replacing the glass slide in the controller 110, the rotation and timing of the servo motor 310, and the subsequent push-out and reset actions of the electromagnetic slider 420 can be accurately controlled. This time control mechanism enables the device to run continuously and efficiently without the need for professional personnel to replace the glass slide, further enhancing its practicality and automation level.

[0073] The adhesive application mechanism 200 includes an adhesive storage box 210, a roller 250, and a sponge strip 270. The cover plate 120 is provided with a through hole 170 for placing the adhesive storage box 210, the adhesive storage box 210 is arranged in the through hole 170 and can be adjusted in height on the cover plate 120, and the cover plate 120 is provided with an adjusting assembly for adjusting the height of the adhesive storage box 210. Specifically, the adhesive storage box 210 and the collection port 160 are located in the same radial direction of the rotating disc 180, and the position of the adhesive storage box 210 is closer to the center of the rotating disc 180 than that of the collection port 160, and the adhesive storage box 210 is arranged adjacent to the collection port.

[0074] The inside of the adhesive storage box 210 is provided with a positioning opening adhesive containing cavity 211, and the bottom surface of the adhesive storage box 210 is also provided with a through adhesive sink cavity 212, which is communicated with the adhesive containing cavity 211 and located at the bottom surface of the adhesive containing cavity 211. The roller 250 is rotationally arranged in the through adhesive sink cavity 212 and protrudes from the bottom surface of the adhesive storage box 210. The through adhesive sink cavity 212 is provided with a through adhesive cotton 240 and a screen 230, the through adhesive cotton 240 is arranged in the adhesive containing cavity 211 and contacts the roller 250, and the screen 230 is arranged on the through adhesive cotton 240.

[0075] In view of the fact that long-term exposure of the adhesive may cause chemical property changes due to environmental factors (such as temperature, humidity, etc.), resulting in a decrease in viscosity and affecting the pollen adhesion effect; at the same time, too long exposure time may also cause the adhesive to adsorb dust, microorganisms and other impurities in the air, interfering with the results of pollen collection and analysis. Therefore, in the present application: when it is necessary to collect air samples on the slides or replace new slides, the slides will pass through the adhesive storage box 210 and the collection port 160 in turn to achieve the purpose of instant adhesive coating. The specific operation steps are as follows:

[0076] The slide is first driven by the collection box 500 to pass through the adhesive storage box 210, at which time the surface of the slide will contact the adhesive preloaded in the adhesive storage box 210, and a layer of fresh adhesive will be evenly coated by the action of the roller 250, ensuring the freshness of the adhesive and its good adhesion performance; then, the slide continues to move and reaches the position of the collection port 160, starting the normal air sample collection task. In this way, the slide has just completed the adhesive coating process before entering the collection port 160, enhancing the adhesion of its surface, so that it can more effectively capture and fix the pollen particles in the air, avoiding the loss of pollen due to changes in external conditions (such as wind speed), improving the collection efficiency and quality.

[0077] The screen 230 is provided to ensure that the adhesive can be evenly permeated into the adhesive-permeable cotton 240. By laying the adhesive-permeable cotton 240 in the adhesive dissolving chamber, the adhesive is blocked, preventing excessive flow and dripping. By using the contact between the adhesive-permeable cotton 240 and the roller 250, the permeated adhesive is coated on the roller 250 as the roller 250 rolls in contact with the adhesive-permeable cotton 240, and is rolled on the surface of the slide when the slide is contacted.

[0078] The adhesive coating mechanism 200 also includes a sponge strip 270, which is fixedly connected to the bottom surface of the adhesive storage box 210, and the sponge strip 270 is arranged closer to the center of the turntable 180 relative to the roller 250, that is, the slide will first contact the sponge strip 270 during the process of being pushed out of the adhesive coating process, so that the sponge strip 270 will clean the surface of the slide.

[0079] The adhesive coating mechanism 200 further comprises at least one scraper 260, which is also fixedly connected to the bottom surface of the adhesive storage box 210 and symmetrically arranged with respect to the roller 250. The plurality of scrapers 260 are uniformly arranged along the length direction of the adhesive storage box 210, i.e., the direction of the movement of the paddle. The scraper 260 is provided with a V-shaped notch 261 on the side facing the roller 250, and the opening direction of the V-shaped notch 261 is arranged towards the direction of the roller 250. The opening direction of the V-shaped notch 261 is arranged along the length direction of the scraper 260.

[0080] When the roller 250 applies adhesive to the surface of the slide, the slide will continue to move and contact the scraper 260. The scraper 260 performs a scraping action on the adhesive on the slide. Through the multiple scraping actions of the plurality of scrapers 260, the adhesive on the surface of the slide is ensured to be flat and uniform after passing through the adhesive coating mechanism 200. In this process, the excess adhesive is collected in the V-shaped notch 261, and the position with less adhesive on the slide during the subsequent scraping process is supplemented.

[0081] The adhesive coating mechanism 200 further comprises a sealing cover 220 and a heating plate. The sealing cover 220 is used to seal the top opening of the adhesive storage box 210 to prevent the adhesive inside the adhesive storage box 210 from solidifying. The heating plate is fixedly installed on the inner side wall of the adhesive storage box 210, and the heating plate is electrically connected with the controller 110. The controller 110 is used to control the heating of the adhesive in the adhesive storage box 210 before each rotation of the rotating disc 180, so that the adhesive storage box 210 is kept at a constant temperature or a set temperature, and the fluidity of the adhesive in the adhesive storage box 210 is ensured.

[0082] The adhesive coating mechanism 200 further comprises a limiting piece 610, which is used to limit the movement of the box cover 520 when the box cover 520 is separated from the box bottom 510. In this way, when the electromagnetic slider 420 pushes the box bottom 510 to move, the limiting piece limits the movement of the box cover 520, so as to facilitate the separation of the box cover 520 from the box bottom 510.

[0083] The limiting piece 610 is a limiting block fixedly installed on the adhesive storage box 210. The limiting block is provided with a limiting groove 620 facing the center of the rotating disc 180. The box cover 520 is fixedly connected with a positioning block 590, which is arranged at the position of the second inclined block 580 of the box cover 520. In this way, the positioning block 590 can rotate and slide through the limiting groove 620 during the rotation of the rotating disc 180. When collecting air samples, the positioning block 590 on the box cover 520 of the collection box 500 containing the slide is located in the limiting groove 620. When the box bottom 510 is pushed to slide, the box cover 520 is separated from the box bottom 510 by the limiting action of the positioning block 590.

[0084] The adjusting assembly comprises a motorized slide 280 fixedly connected to the bottom surface of the cover plate 120, the length extension direction of the motorized slide 280 is perpendicular to the plane of the cover plate 120, a motorized slide block 290 is slidably arranged on the motorized slide 280, the motorized slide block 290 is fixedly connected to the adhesive storage box 210, so that the motorized slide block 290 can carry the adhesive storage box 210 to move in the height direction, and the active space of the limiting block 590 in the sliding process is arranged in the limiting groove 620.

[0085] The motorized slide block 290 is electrically connected with the controller 110, when the limiting block 590 is clamped in the limiting groove 620, the limiting block 590 has a certain distance from the bottom surface of the limiting groove 620, at this time, when the box bottom 510 is pushed out to slide to the collection port 160, the limiting block 590 of the box cover 520 abuts against the side wall of the limiting groove 620, when the box bottom 510 is completely separated, the limiting block 590 falls downward to contact the bottom surface of the limiting groove 620 under the gravity of the box cover 520 itself. When the box bottom 510 is retracted and reset, the controller 110 controls the motorized slide block 290 to move to drive the adhesive storage box 210 to move upward, the moving distance is equal to the falling distance of the limiting block 590, so as to ensure that the dovetail strip 540 is aligned and inserted into the dovetail groove 530, and the roller 250 avoids secondary coating of the adhesive on the glass slide.

[0086] In this way, the automatic replacement and adhesive coating of the glass slide without human intervention are realized.

[0087] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
