Description

Technical Field

[0001] The invention belongs to the technical field of pollen detection, and in particular to the technical field of portable pollen detection equipment. Background Art

[0002] Hay fever is one of the most common allergic diseases, and its incidence has been increasing rapidly in recent years. The incidence of hay fever in Europe has risen to 20%, more than a quarter of people in Japan suffer from hay fever, and the rate of allergy to ragweed pollen alone in the United States has reached 26%. Since pollen is very fine and difficult to observe, some detection devices are needed to detect it.

[0003] For example, Chinese application No. 201922061399.5 discloses a pollen detection device including a fixed platform, a qualified conveyor belt arranged on one side of the fixed platform, and an unqualified conveyor belt arranged on the other side of the fixed platform, the upper surface of the fixed platform is provided with two side-by-side left-moving track grooves, and the upper surface of the fixed platform is provided with two side-by-side right-moving track grooves, the left-moving track grooves and the right-moving track grooves are arranged at intervals, two side-by-side screw rods are rotatably installed inside the fixed platform, the circumferential external thread of the screw rod is connected with a stroke nut, a hydraulic cylinder is installed above the stroke nut, and a push rod is installed at the upper end of the hydraulic cylinder.

[0004] Most of the current detection equipment, like the above-mentioned equipment, are large-scale detection equipment. Although they can perform detection operations, people inevitably need to walk outside when spring comes and flowers bloom. There will be a lot of pollen in the air at this time, but these pollens are very fine and people cannot observe them directly, so people will unknowingly come into contact with a large amount of pollen, resulting in signs of allergies. How to identify allergenic plants in the environment and detect the size and concentration of pollen particles they spread in real time to provide early warning forecasts for people prone to allergies has become an urgent problem that people need to solve.

[0005] On the other hand, currently in the laboratory, vaseline is used, and safranin solution is applied at the same time, so that the active pollen is colored and visible to distinguish the particle size and concentration of pollen. This method is relatively cumbersome. Now, biosensors are used to generate different electronic signals for pollen, a viable substance, and the electronic signals generated are different with different types and particle sizes. Different pollens are tested on biosensors in advance to obtain pollen type data and store them in the database in advance, so as to be used as a comparison during detection, thereby obtaining the type, particle size and concentration of pollen.

[0021] 2. The structure of the portable allergenic pollen detector of the present invention for collecting pollen adopts vaseline tape and smears safranin solution at the same time, so that the pollen stuck on the vaseline tape will be revealed, thereby distinguishing it from other sundries stuck on the vaseline tape, thereby ensuring the accuracy of the data captured by the camera.

[0022] 3.

[0023] 4. The portable allergenic pollen detector of the present invention is used in combination by setting a shell, a limit sleeve, a second air inlet, a biosensor, a fan, a filter, a second battery pack, a display screen, a second switch, a back cover and a second air outlet. The second switch is turned on for about thirty seconds at a place where detection is required, so that the surrounding air to be detected is fully inhaled through the fan. At this time, the second air outlet cannot be blocked to prevent the inhaled air from being unable to be discharged. The second switch is closed, and the data on the size and concentration of pollen particles on the display screen are read. If it is displayed as 0, the air detected here does not contain pollen. Doing so can facilitate the device to be carried and used outdoors, thereby enhancing the efficiency of pollen detection.

[0024] 5. The portable allergenic pollen detector of the present invention is used in combination of a connecting plate, a fixed cylinder, a card block, a second card slot, a second spring, a moving block and a slot. The moving block is pulled to slide along the inner wall of the slot and the card block is pushed to separate from the inside of the second card slot. At this time, the staff can pull the connecting plate to the right to separate the back cover from the inner wall of the shell, thereby facilitating the cleaning of the biosensor and the fan inside the shell. This method improves the cleaning efficiency and ensures that the equipment can work for a long time when used outdoors.

[0025] 6. The portable allergenic pollen detector of the present invention is used in combination of a protective plate, a pushing block, a protective pad, a guide sleeve, a guide rod, a vertical plate, a third spring and a baffle. The protective plate and the protective pad are moved to the left by pulling the pushing block, and the guide sleeve is made to slide along the outer wall of the guide rod, driving the third spring to be squeezed and compressed. Then, the display screen value is observed. After the observation is completed, the pushing block is released, and the guide sleeve can be driven to rebound under the elasticity of the third spring, and the protective plate and the protective pad can protect the surface of the display screen. The display screen can be opened for use when it is in use, and can be protected when it is not in use. The problem of scratches on the display screen surface can be avoided during movement.

The present invention uses the electric control box to pick up the information on the photographed picture, thereby detecting the concentration of pollen in real time, and providing early warning and forecast for people prone to allergies.

[0043] Example 1

[0044] like Figures 1 to 4 As shown in the figure, a first embodiment of a portable allergenic pollen detector is provided, which includes a mounting shell 1, an intermittent pollen collecting structure 6 for collecting pollen is arranged inside the mounting shell 1, a pressure cover 3 is threadedly connected to the inside of the mounting shell 1 above the intermittent pollen collecting structure 6, an image acquisition structure 5 is installed inside the pressure cover 3 at a position corresponding to the intermittent pollen collecting structure 6, a guide lining 4 is installed between the pressure cover 3 and the intermittent pollen collecting structure 6, a handheld frame 2 is installed on the side of the mounting shell 1, and an electric control box 20 and a first battery pack 21 are installed inside the handheld frame 2.

[0045] In the technical solution of the present application, pollen enters the interior of the mounting shell 1 through the pressure cover 3, and is then collected by the intermittent pollen collecting structure 6. The pollen collected on the intermittent pollen collecting structure 6 is photographed by the image acquisition structure 5, and then the collected data is sent to the electronic control box 20 for processing. The information on the photographed image is picked up by the electronic control box 20, thereby performing real-time detection of the pollen concentration, and providing early warning forecasts for people prone to allergies.

[0046] like Figure 5 The working method of the portable allergenic pollen detector according to the first embodiment of the present invention includes the following steps:

[0047] Step S1, turn on the instrument switch, initialize the instrument, and select whether to enter the main process interface.

[0048] Step S2, after the instrument configuration is completed, choose whether to return to the main process to proceed to the next step; if you choose not to return to the main process, return to the previous step to configure the instrument; if you return to the main process, proceed to the next step, slide counting;

[0049] Step S3, if the slide counting result reaches the set number, the instrument will pop up a slide change prompt and enter the standby state; if the slide counting result does not reach the set number, choose whether to enter the main process. If you choose to enter the main process, set the timer count. If the set timer does not reach the set time and does not reach the set number, return to the main process to reset;

[0050] Step S4, if the set timer has not reached the set time, but has reached the set number, a reminder to change the film will pop up and enter the standby state; if the set timer has reached the set time, proceed to the next step;

[0051] Step S5, image acquisition, data storage, and data upload. After uploading the data, the slides are counted. If the number reaches the set number, the instrument will pop up a slide change prompt and enter the standby state;

[0052] Step S6: If the number does not reach the set number, return to the main process and perform a new round of data collection.

[0053] Example 2

[0054] like Figures 1 to 4As shown in, on the basis of Example 1, the intermittent pollen collecting structure 6 includes a partition 7 and a partition 2 47 arranged inside the mounting shell 1, and a collecting rod 8 and a vaseline tape mounting roller 9 are rotatably mounted between the partition 1 7 and the partition 2 47, and the bottom ends of the collecting rod 8 and the vaseline tape mounting roller 9 are both provided with a pulley 10, and the two pulleys 10 are connected by a belt 11, the pulley 10 is arranged below the partition 2 47, the top end of the collecting rod 8 is arranged above the partition 1 7 and is connected to the gear 2 14, and the mounting shell 1 is installed with a servo motor 12 inside, and a gear 13 is installed on the output shaft of the servo motor 12. The gear 13 and the gear 2 14 are meshed and connected. The servo motor 12 drives the collecting rod 8 to rotate under the transmission of the gear 13 and the gear 2 14, and drives the vaseline tape installation roller 9 to rotate under the transmission of the pulley 10 and the belt 11, so that the vaseline tape 18 outside the vaseline tape installation roller 9 can smoothly reach the collecting rod 8, thereby switching the vaseline tape 18 for collecting pollen.

[0055] A support shaft 15 is rotatably installed between the partition 1 7 and the partition 2 47 above the collecting rod 8, and a support shaft 2 16 is rotatably installed between the partition 1 7 and the partition 2 47 above the vaseline tape installation roller 9. The support shaft 2 16 is arranged higher than the support shaft 15. A first air outlet 19 is opened at the side of the installation shell 1 corresponding to the area between the support shaft 15 and the collecting rod 8. The structural arrangement of the support shaft 15 and the support shaft 2 16 causes the vaseline tape at the position opposite to the connecting hole 27 to tilt, and the inclined surface of the vaseline tape faces the position of the first air outlet 19, thereby allowing the external air flow to enter through the first air inlet 24, fall onto the vaseline tape through the connecting hole 27, and then be quickly discharged from the position of the first air outlet 19 after being reflected by the vaseline tape, thereby preventing the air flow from contacting the unused vaseline tape.

[0056] The vaseline tape installation roller 9 includes a positioning shaft 36 and a connecting shaft 37. The positioning shaft 36 is rotatably mounted on the partition 1 7, and the connecting shaft 37 is rotatably mounted on the partition 2 47. A mounting groove 38 is provided inside the positioning shaft 36. The interior of the mounting groove 38 is connected to an inner lining plate 40 via a rotating shaft 39. A first clamping groove 41 is provided on the connecting shaft 37 at a position corresponding to the inner lining plate 40. A top ring 42 is installed outside the connecting shaft 37 between the first clamping groove 41 and the partition 2 47. Both ends of the connecting shaft 37 on both sides of the first clamping groove 41 are installed with convex plates 45. A limit ring 44 is slidably installed outside the connecting shaft 37 between the convex plate 45 and the top ring 42. The limiting ring 44 is connected to the top ring 42 through the first spring 43, so that by moving the limiting ring 44 toward the top ring 42, it is convenient to take the inner lining plate 40 out of the first slot 41, so that it is convenient to remove the Vaseline tape installation roller 9 mounted on the inner lining plate 40 for replacement. After the new Vaseline tape installation roller 9 is installed on the outside of the inner lining plate 40, the inner lining plate 40 is stuck inside the first slot 41, and then the limiting ring 44 is loosened, so that under the action of the first spring 43, the limiting ring 44 moves to the position of the convex plate 45, thereby limiting the inner lining plate 40.

[0057] An installation roller 46 is slidably installed on the outside of the inner lining plate 40, and a vaseline tape 18 is wrapped around the outside of the installation roller 46. The surface of the vaseline tape 18 corresponding to the side of the pressure cover 3 is coated with a safranin solution, and the concentration of the safranin solution is set to 0.002% w / v. The vaseline tape 18 passes over the top of the support shaft 15 and the support shaft 2 16 and then sticks to the collecting rod 8, thereby ensuring that the pollen passing through the connecting hole 27 can directly fall onto the vaseline tape 18 between the support shaft 15 and the support shaft 2 16. At the same time, the safranin solution can dye the pollen that falls on the vaseline tape 18, thereby facilitating the subsequent information collection operation.

[0058] The guide liner 4 includes a pad 26 slidably mounted inside the mounting shell 1 between the partition 1 7 and the pressure cover 3, a connecting hole 27 is opened on the pad 26 at a position corresponding to the position between the support shaft 15 and the support shaft 2 16, and a side plate 28 is distributed at the bottom end of the pad 26 on the side of the connecting hole 27. The side plate 28 is set as a U-shaped structure, and the opening of the side plate 28 of the U-shaped structure is set above the support shaft 15. A conical air guide ring 29 is installed on the pad 26 outside the connecting hole 27. The setting of the conical air guide ring 29 ensures that the airflow passing through the pressure cover 3 can quickly reach the connecting hole 27. At the position, the setting of the U-shaped side panel 28 allows the airflow passing through the connecting hole 27 to directly fall on the Vaseline tape 18, and then be reflected by the Vaseline tape 18 and at the same time, under the limitation of the side panel 28, the airflow can be quickly discharged from the position of the first air outlet 19 to prevent the airflow from contacting the unused Vaseline tape 18. A baffle 17 is installed inside the mounting shell 1 below the Vaseline tape 18 between the support shaft 15 and the support shaft 2 16 to prevent the airflow from reaching the position of the Vaseline tape mounting roller 9 from below the Vaseline tape 18.

[0059] Example 3

The first battery pack 21 provides the required power for the overall operation. The electric control box 20 is internally provided with a main control module, a communication module, a power module, a storage module, an image processing module, a timing module and an alarm module. The time is set by the timing module, mainly setting the working interval of the servo motor 12 and the shooting time of the camera 32, wherein the picture information shot by the camera 32 is processed by the fifo processing chip inside the image processing module and then The information is then sent to the main control module. The main control module sends the information to the user's handheld device through the 5g network inside the communication module according to the processing result. When the camera 32 is shooting, the fill light 31 also works to ensure the clarity of the shooting. The set data is stored through the storage module. The power module is provided with a voltage stabilizing chip, a charging chip and a battery interface, thereby controlling the operation of the first battery pack 21. The alarm module is provided with a buzzer. When the pollen concentration information obtained after processing is greater than the set information, the electric control box 20 makes the buzzer work, thereby reminding the user. The working process of the electric control box 20 is as follows Figure 5 as shown in .

[0061] A first air inlet 24 is provided on the pressure cover 3, and an air suction fan 25 is installed on the surface of the pressure cover 3 corresponding to the side of the guide lining plate 4. The image acquisition structure 5 includes a fixing plate 30 installed on the inner side of the pressure cover 3, and a fill light 31 and a camera 32 are installed on the surface of the fixing plate 30 corresponding to the side of the guide lining plate 4. The air suction fan 25, the fill light 31 and the camera 32 are connected with a wire 33, and a plug 34 is installed at the end of the wire 33. A socket 35 is provided on the side of the electric control box 20 corresponding to the plug 34. The plug 34 is inserted into the inside of the socket 35, thereby completing the connection between the air suction fan 25, the fill light 31, the camera 32 and the electric control box 20. When the air suction fan 25 works, the external air flow flows along the first air inlet 24, the conical air guide ring 29, the connecting hole 27, the surface of the vaseline tape 18 between the support shaft 15 and the support shaft 2, and the first air outlet 19, and the information collection operation is performed on the pollen collected on the surface of the vaseline tape 18 through the camera 32.

[0065] Reference Figure 6-Figure 12 As shown, a portable allergenic pollen detector includes a shell a-1, the shell a-1 has a chamber inside, the left end of the shell a-1 is sleeved with a limiting sleeve a-211, and the right end is connected to a back cover a-219 through a limiting mechanism, a second air inlet a-212 is opened inside the limiting sleeve a-211, and a second air outlet a-220 matching the second air inlet a-212 is opened inside the back cover a-219, air containing pollen enters the shell a-1 through the second air inlet a-212 for detection, and is discharged to the outside through the second air outlet a-220, thereby achieving an air circulation effect. It also includes a biosensor a-213, a fan a-214, a filter a-215 and a second battery pack a-216 which are located inside the shell a-1 and are arranged in sequence from left to right. A second switch a-218 is installed on the outer wall of the shell a-1, and a display screen a-217 is installed on the top of the shell a-1. The biosensor a-213, the fan a-214, the second battery pack a-216, the display screen a-217 and the second switch a-218 are connected by wires. The air containing pollen is adsorbed on the biosensor a-213 through the operation of the fan a-214 for detection and processing, and the detection results are displayed through the display screen a-217. The whole detection principle is: pollen contains active substances such as protein, amino acids, and active enzymes. These substances can generate electronic signals through the biosensor a-213, and different pollen and particle sizes generate different electronic signals, and the amount of pollen can also be intuitively reflected. Inactive substances such as dust and impurities in the air will not generate electronic signals. The electronic signal converted from the pollen is compared with the pollen database pre-stored in the chip to identify the particle size, type and quantity concentration of the pollen, and the data is reflected on the display screen a-217.

[0066] Open the second switch a-218 for about thirty seconds at the place that needs to be tested, so that the surrounding air to be tested can be fully inhaled through the fan a-214. At this time, the second air outlet a-220 cannot be blocked to prevent the inhaled air from being unable to be discharged. Close the second switch a-218 and read the data on the pollen particle size and concentration on the display screen a-217. If it shows 0, the air detected here does not contain pollen.

[0067] The limiting mechanism includes a connecting plate a-311, a fixed cylinder a-312, a block a-313 and a second slot a-314. The connecting plate a-311 is fixed to the outer wall of the back cover a-219, the outer wall of the shell a-1 is fixed with a fixed cylinder a-312, the inside of the fixed cylinder a-312 is inserted with a block a-313, and the inner wall of the connecting plate a-311 is provided with a second slot a-314 which matches the block a-313. By putting the back cover a-219 on the inner wall of the shell a-1 and then pulling the block a-313 to insert it into the second slot a-314, it can be used to limit the problem of the back cover a-219 falling off from the shell a-1, thereby enhancing the stability of the equipment. A second spring a-315 is arranged inside the fixed cylinder a-312, one end of the second spring a-315 is connected to the block a-313, and the other end is connected to the inner wall of the fixed cylinder a-312. The second spring a-315 can play a good elastic effect. In the initial state, the second spring a-315 will push the block a-313 to move away from the shell a-1, so that the block a-313 can be stably inserted into the second slot a-314. A moving block a-316 is fixed on the top of the block a-313, and a slot a-317 matching the moving block a-316 is provided on the top of the fixed cylinder a-312. Moving the moving block a-316 can make it slide along the inner wall of the slot a-317, so as to achieve a better moving purpose and be relatively easy to operate.

[0068] A protective mechanism is provided at the top of the shell a-1, and the protective mechanism includes a protective plate a-411, a pushing block a-412 and a protective pad a-413. The protective plate a-411 is slidably connected to the top of the shell a-1, and a protective pad a-413 is fixed to the bottom of the protective plate a-411 and a pushing block a-412 is fixed to the top. The protective plate a-411 can be slidably slidably to block or detach the display screen a-217. The display screen a-217 can be protected during carrying to prevent the surface of the display screen a-217 from being scratched. When in use, the display screen a-217 is opened for people to observe. A guide sleeve a-414 is fixed to the outer wall of the protective plate a-411, a vertical plate a-416 is fixed to the top of the shell a-1, a guide rod a-415 penetrating the guide sleeve a-414 is fixed to the outer wall of the vertical plate a-416, and the guide sleeve a-414 can slide along the outer wall of the guide rod a-415, thereby enhancing the stability of the lateral movement of the protective plate a-411. A baffle a-418 is fixed to one end of the guide rod a-415 away from the vertical plate a-416, and the diameter of the baffle a-418 is larger than that of the guide rod a-415. The baffle a-418 can prevent the protective plate a-411 from moving to the right and falling off, thereby achieving a better protection purpose. A third spring a-417 is wound around the outer wall of the guide rod a-415, one end of the third spring a-417 is connected to the guide sleeve a-414, and the other end is connected to the vertical plate a-416. The provision of the third spring a-417 can ensure that the rebound and reset of the protective plate a-411 is sufficiently stable, so that the equipment can be used multiple times.

[0069] The working principle of embodiment 4 of the present invention: when in use, open the limit sleeve a-211, clean the exposed surface of the biosensor a-213 with wet tissue or clean water, then close the limit sleeve a-211, and open the second switch a-218 for about thirty seconds at the place where detection is required, so that the surrounding air to be detected is fully inhaled through the fan a-214. At this time, the second air outlet a-220 cannot be blocked to prevent the inhaled air from being unable to be discharged. Close the second switch a-218, and read the data on the pollen particle size and concentration on the display screen a-217. If it shows 0, the air detected here does not contain pollen.

[0070] When it is necessary to open the back cover a-219 to clean the inside of the shell a-1, pull the moving block a-316 to make it slide along the inner wall of the slot a-317, and push the card block a-313 to disengage from the inside of the second card slot a-314. At this time, the staff can pull the connecting plate a-311 to the right to disengage the back cover a-219 from the inner wall of the shell a-1, thereby facilitating the cleaning of the biosensor a-213 and the fan a-214 inside the shell a-1.

[0071] When the display screen a-217 needs to be protected, the protective plate a-411 and the protective pad a-413 are moved to the left by pulling the push block a-412, and the guide sleeve a-414 is made to slide along the outer wall of the guide rod a-415, thereby causing the third spring a-417 to be squeezed and compressed. Then, the value of the display screen a-217 is observed. After the observation is completed, the push block a-412 is released, and the guide sleeve a-414 can be driven to rebound under the elasticity of the third spring a-417, so that the protective plate a-411 and the protective pad a-413 can protect the surface of the display screen a-217.

[0072] Compared with the prior art, the portable allergenic pollen detector of the present invention turns on the second switch for about thirty seconds at the place where detection is required, so that the surrounding air to be detected is fully inhaled through the fan. At this time, the second air outlet cannot be blocked to prevent the inhaled air from being unable to be discharged. The second switch is closed, and the data on the pollen particle size and concentration on the display screen is read. If the display is 0, the air detected here does not contain pollen. Doing so can facilitate the device to be carried and used outdoors, thereby enhancing the efficiency of pollen detection and other advantages.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
