Description

Technical Field

[0001] The present invention relates to the technical field of biological sample detection, and specifically to a device for quantitatively detecting biological samples. Background Art

[0002] Biological sample detection refers to the process of analyzing and detecting various samples derived from organisms (including humans, animals, plants, and microorganisms). Foods mainly come from organisms, including plants, animals, and microorganisms. In biological sample detection, there will be detections of food samples to analyze the components of foods and evaluate their safety and quality. The rate of biochemical reactions is affected by temperature. Generally, an increase in temperature will accelerate the reaction rate. Therefore, it is necessary to quantitatively process the temperature of food samples before detection. The standardized processing of temperature can help experimenters reduce the interference of temperature on the results and make the results between different experiments more comparable.

[0003] When detecting food samples, it is first necessary to collect the samples and place the collected samples in a specific environment for quantitative processing. After processing, the food samples are extracted to the detection table for detection, and the detection of food samples is completed. For example, the patent with the publication number CN214668872U discloses a biological experiment box convenient for biological sample detection, including four anti-slip pads. The top of the four anti-slip pads is fixedly connected with support legs, and the top of the support legs is fixedly connected with a box body. A storage room is opened at the bottom of the box body. This technology reduces the possibility of sample contamination during placement through the provided induction unlocking mechanism, and the provided ventilation mechanism keeps the experimental detection environment simulate the normal state of nature, improving the accuracy of detection data.

[0004] However, in the above technology, although the experimental detection environment is kept to simulate the normal state of nature through the ventilation mechanism, after the airflow generated by the fan is simply filtered by the filter plate, there is an air interaction between the box body and the outside. During the air interaction process, not only will the temperature inside and outside the box body be the same, making it impossible to quantitatively process the temperature of the samples inside the box body, but also due to the air interaction, miscellaneous bacteria outside the box body enter the box body, contaminating the samples and thus affecting the subsequent detection results.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] By providing a disinfection mechanism, a drying mechanism and a temperature control mechanism, when the gas is discharged from the storage chamber, the air flow velocity on the outer wall of the drying plate is increased, the moisture in the drying plate is reduced, thereby improving the drying effect of the drying plate in the absorption box on the gas entering the storage chamber, preventing moisture from affecting the sample. In addition, the control piece is provided not only to cool the air when the external air enters the storage chamber, so as to realize the quantitative temperature control of the sample, but also, since the surface temperature of the cold end of the control piece is low, the water vapor inside the disinfected air condenses after contacting the cold end of the low-temperature control piece, thereby further reducing the humidity of the air discharged from the storage chamber. When the temperature of the sample is quantitatively controlled, the humidity of the disinfectant is reduced as much as possible to affect the storage of the sample, thereby improving the accuracy of the detection;

The storage tank 9 is used to store disinfectant. One end of the liquid inlet pipe 5 is fixedly connected to the outer wall of the storage tank 9, and the other end of the liquid inlet pipe 5 extends to the outer wall of the body shell 1.

A return pipe 18 is fixedly installed on the bottom surface of the return cylinder 11, and the other end of the return pipe 18 is fixedly connected to the outer wall of the storage tank 9. The height of the return cylinder 11 is not lower than the height of the storage tank 9. A solenoid valve is arranged at any position in the return pipe 18.

[0051] It should be noted that in this embodiment, the sample is a food sample, and the detection item is the acidity and alkalinity of the food sample in different temperature environments. A pH detection table 40 and an analysis computer 39 are arranged at the upper end of the body shell 1. After the quantitatively processed sample is smeared on the pH detection table 40, the sample on the pH detection table 40 is analyzed by the analysis computer 39 (detecting the acidity and alkalinity of the liquid through the pH detection table 40 and analyzing it by the analysis computer 39 is a well-known prior art and will not be elaborated too much). Finally, the acidity and alkalinity data of the sample at the corresponding temperature are detected.

[0052] In this embodiment, the partition plate 7 is fixedly installed inside the body shell 1, dividing the body shell 1 into an installation chamber and a storage chamber. The installation chamber provides an installation space for electronic components, and the storage chamber provides a storage space for samples. During detection, first, the sample needs to be placed on the carrier plate 2, and then the external cabinet door of the body shell 1 is closed. When injecting air into the storage chamber, the control pump 8 is started to fill the external gas into the disinfectant solution inside the storage tank 9, thereby achieving air disinfection. After the control pump 8 injects air into the disinfectant solution, the air accumulates at the upper part of the storage tank 9 due to buoyancy. A conduit communicating with the absorption tank 17 is provided at the upper end of the storage tank 9, and then the air enters the absorption tank 17 through the conduit. At this time, the drying plate 19 inside the absorption tank 17 absorbs the moisture in the air, achieving a drying effect, and then is discharged into the cooling tank 12 for cooling. The control piece 23 cools the heat exchange plate 24, and the air contacts the outer wall of the heat exchange plate 24 when passing through, thereby achieving air cooling. The cooled air is discharged into the storage chamber through the intake pipe 14, thereby controlling the temperature of the environment where the sample is located and realizing quantitative processing of the sample temperature. At this time, the exhaust pipe 6 discharges the gas in the storage chamber on one side of the partition plate 7 to the moisture exhaust box 10, and the air passes through the moisture exhaust box 10, thereby increasing the air flow velocity on the surface of the drying plate 19 at one end of the moisture exhaust box 10, realizing the self-drying process of the drying plate 19, and improving the service life of the drying plate 19. When adding disinfectant solution, the sealing cap is unscrewed and then the disinfectant solution is injected into the inside of the storage tank 9 to achieve the replenishment of the disinfectant solution. One end of the drying plate 19 is located inside the absorption tank 17 and the other end is inside the moisture exhaust box 10. During the air intake process, the gas passes through the inner cavity of the absorption tank 17 and is absorbed and dried by the drying plate 19. At this time, the drying plate 19 absorbs water vapor, and due to capillary action, the moisture will be conducted and extended along the drying plate 19. On this basis, the inside of the moisture exhaust box 10 exhausts air, and at this time, the air flow velocity on the outer wall of the end of the drying plate 19 located inside the moisture exhaust box 10 is increased, thereby taking away the moisture. When a part of the moisture of the drying plate 19 decreases, due to capillary action, its overall moisture will be reduced, thereby achieving the self-drying effect of the drying plate 19. When discharging gas from the storage chamber, the air flow velocity on the outer wall of the drying plate 19 is increased, and the moisture inside the drying plate 19 is reduced, thereby improving the drying effect of the drying plate 19 inside the absorption tank 17 on the gas entering the storage chamber, preventing moisture from affecting the sample. In addition, setting the control piece 23 can not only cool the air when the external air enters the storage chamber, thereby realizing quantitative processing of the sample temperature, but also, since the surface temperature of the cold end of the control piece 23 is low, the water vapor inside the disinfected air condenses after contacting the cold end of the low-temperature control piece 23, thereby further reducing the humidity of the air discharged from the storage chamber. When quantitatively processing the sample temperature, the humidity of the disinfectant solution is reduced as much as possible to affect the storage of the sample, thereby improving the accuracy of later detection. At the same time, when the air enters the inner cavity of the cooling tank 12, condensation water droplets are formed on the surface of the heat exchange plate 24 when it meets the cold, and flow into the inner cavity of the reflux cylinder 11 under the action of gravity, thereby realizing the recovery of the disinfectant solution. At this time, the solenoid valve is opened,The recycled disinfectant liquid is made to flow back into the interior of the storage tank 9 for the recycling and reuse of the disinfectant liquid. The heat exchange plate 24 is cooled by the control piece 23. When the disinfected air passes through the inner cavity of the cooling box 12, not only is the cooling treatment of the air achieved, and then the quantitative treatment of the sample temperature is realized, but also the humidity of the air introduced into the storage chamber is reduced by condensation. In addition, the disinfectant liquid is recovered by condensation, the utilization rate of the disinfectant liquid is improved, and the use cost is reduced.

[0053] Embodiment 2: Please refer to Figure 4 - Figure 9 This embodiment further illustrates Embodiment 1. A plurality of heat exchange plates 24 are provided, and the plurality of heat exchange plates 24 are uniformly distributed along the inner wall of the cooling box 12 (as Figure 6 shown). A scraping plate 29 is arranged inside the cooling box 12, and the outer wall of the scraping plate 29 is slidably attached to the outer wall of the heat exchange plate 24. A converging pipe 25 is fixedly installed on the inner wall of the return cylinder 11. A closing plug 26 for closing the converging pipe 25 is arranged at the bottom of the converging pipe 25, and the closing plug 26 slides synchronously with the scraping plate 29.

[0054] An installation bracket 27 is fixedly installed on the upper end surface of the cooling box 12. An installation cylinder 21 is fixedly installed on the inner wall of the installation bracket 27. A control rod 28 is slidably arranged inside the installation cylinder 21. One end of the control rod 28 extends into the inner cavity of the cooling box 12 and is fixedly connected to the upper end surface of the scraping plate 29. A connecting rod 30 is fixedly installed on the bottom surface of the scraping plate 29, and the other end of the connecting rod 30 is fixedly connected to the upper end surface of the closing plug 26.

[0055] A driven plug 31 is slidably installed on the inner wall of the installation cylinder 21. The bottom surface of the driven plug 31 is fixedly connected to the outer wall of the control rod 28. A temperature sensing cylinder 15 is fixedly installed at the hot end of the control piece 23. A guiding cylinder 20 is fixedly installed on the upper end surface of the temperature sensing cylinder 15. The inner cavity of the guiding cylinder 20 communicates with the inner cavity of the installation cylinder 21.

[0056] A driving plug 32 is elastically installed on the inner wall of the guiding cylinder 20. The radial outer wall of the driving plug 32 is sealingly attached to the inner wall of the guiding cylinder 20. A pressure relief hole 22 is formed in the outer wall of the temperature sensing cylinder 15. A closing ring 35 for closing the pressure relief hole 22 is arranged on the inner wall of the temperature sensing cylinder 15. The closing ring 35 is connected to the inner wall of the temperature sensing cylinder 15 by friction. Two blocking rings 34 are fixedly installed on the inner wall of the temperature sensing cylinder 15, and the two blocking rings 34 are respectively located at the two axial ends of the closing ring 35.

[0057] A connecting frame 36 is fixedly installed on the inner wall of the closing ring 35. A transmission cylinder 37 is slidably installed on the inner wall of the connecting frame 36. A transmission piece 38 is fixedly installed on the inner wall of the transmission cylinder 37. A transmission shaft 33 for fixedly connecting to the bottom surface of the driving plug 32 is fixedly installed at the upper end of the transmission piece 38.

[0058] In this embodiment, when the air enters the cooling box 12, it contacts with a plurality of heat exchange plates 24 at the same time, thereby improving the cooling effect on the air. When condensed water droplets appear on the outer wall of the heat exchange plate 24, the scraper plate 29 is slid from top to bottom to scrape off the water droplets on the outer wall of the heat exchange plate 24, so as to collect the water droplets on the outer wall of the heat exchange plate 24. Scraping off the water droplets on the outer wall of the heat exchange plate 24 can not only improve the recovery efficiency of the disinfectant, but also facilitate direct contact between the external air and the outer wall of the heat exchange plate 24 after removing the water droplets on the outer wall of the heat exchange plate 24, thereby improving the cooling efficiency of the air. When the scraper plate 29 slides downward to scrape off the water droplets on the outer wall of the heat exchange plate 24, the sealing plug 26 slides downward synchronously, thereby keeping the converging pipe 25 open, so as to facilitate the flow of disinfectant. When the scraper plate 29 slides upward When sliding back, the closing plug 26 slides upward to fit with the converging tube 25. At this time, the converging tube 25 is closed. As the cold end of the control plate 23 is cooled, the control plate 23 is a common semiconductor refrigeration plate. After power is turned on, its cold end is cooled to provide a cold source for cooling the storage chamber. The hot end of the control plate 23 gradually releases heat, thereby transferring the heat to the temperature sensing tube 15. The temperature sensing tube 15 is made of copper to maintain the heat conduction effect, resulting in the temperature of the temperature sensing tube 15 to increase, and the air inside it expands, thereby controlling the active plug 32 to slide. A spring is fixedly installed on the upper end surface of the active plug 32, and the other end of the spring is fixed to the inner wall of the guide tube 20. After the temperature inside the temperature sensing tube 15 increases, the active plug 32 slides upward, thereby controlling the air pressure in the inner cavity of the installation tube 21 to increase, and the control plate When the hot end of 23 is heated, the temperature of the temperature-sensing cylinder 15 rises, and the active plug 32 slides upward, driving the transmission cylinder 37 to slide. As the active plug 32 slides upward, until the bottom surface of the transmission cylinder 37 contacts the connecting frame 36, the active plug 32 continues to slide upward, thereby driving the connecting frame 36 and the closed ring 35 to slide upward until the pressure relief hole 22 is connected, and the inner cavity of the temperature-sensing cylinder 15 begins to release pressure. During this process, the air pressure in the installation cylinder 21 increases, and at the same time, the scraper plate 29 is controlled to slide downward to scrape off the water droplets on the outer wall of the heat exchange plate 24. When the pressure relief hole 22 is connected, the spring pushes the active plug 32 to reset. At this time, the transmission cylinder 37 slides downward along the inner wall of the connecting frame 36. During this process, the closed ring 35 is interference-fitted with the inner wall of the temperature-sensing cylinder 15 through friction to maintain pressure relief. The hole 22 is in the conducting state. With the reset of the active plug 32, the transmission cylinder 37 slides downward until the outer wall of the transmission cylinder 37 fits the outer wall of the connecting frame 36, thereby pushing the connecting frame 36 to slide downward until the closed ring 35 closes the pressure relief hole 22 again, so that the temperature sensing cylinder 15 heats up again and the air in the inner cavity expands, which is used to control the scraper plate 29 to scrape the water droplets on the outer wall of the heat exchange plate 24 by utilizing the useless heat of the hot end of the control plate 23. During the sliding process of the closed ring 35, the sliding stroke of the closed ring 35 is limited by the blocking ring 34. At the same time, the scraper plate 29 is controlled to scrape the water droplets on the outer wall of the heat exchange plate 24 by utilizing the useless heat of the hot end of the control plate 23, thereby realizing the reuse of energy. Scraping the water droplets on the outer wall of the heat exchange plate 24 can not only improve the recovery efficiency of the disinfectant,Meanwhile, after removing the water droplets on the outer wall of the heat exchange plate 24, it is convenient for the external air to directly contact the outer wall of the heat exchange plate 24, thereby improving the cooling efficiency of the air, maintaining the stable control of the temperature in the storage chamber, and further improving the efficiency of sample temperature quantification for improving the accuracy of detection.
