[0007] In the above technical solution, preferably, the turntable is provided with a second electric push rod that is evenly distributed and corresponds to the mounting groove. The output shaft of the second electric push rod passes through the interior of the mounting groove and is rotatably connected to one end of the sampling cylinder.

[0008] In the above technical solution, preferably, the turntable has an installation cavity located between the two installation slots, the installation cavity is equipped with an air pump, and the inner wall of the installation cavity has two connecting channels that are respectively connected to the two adjacent installation slots. The air pumping direction is guided by the connecting channels to form a clockwise flow.

[0009] In the above technical solution, preferably, the driving component includes a motor disposed below the placement plate and located on the side of the partition plate away from the collection area. The output shaft of the motor is fixedly connected to a drive shaft, and a connecting shaft is fixedly connected to one side of the turntable. One end of both the drive shaft and the connecting shaft passes through the housing and is fixedly connected to a transmission wheel. A transmission belt is provided on the surface of the transmission wheel, and the two transmission wheels are connected by transmission belt.

[0010] In the above technical solution, preferably, a rotating disk located inside the collection area is fixedly connected to the surface of the drive shaft, and a collection shell is fixedly connected to the surface of the rotating disk in a uniformly distributed manner and in a number equal to that of the installation slot.

The sampling module, combined with a spiral guide groove and an air pump, enables the sampling cylinder to rotate and cut into the sample during its downward movement. At the same time, negative pressure is used to firmly adsorb the sample inside the sampling cylinder. When it is necessary to discharge the sample, positive pressure can be created by injecting air through an adjacent air pump to smoothly push the sample out to the collection container.

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-8 The illustrated virus testing device for logistics includes a housing 1, a baffle 101 slidably connected to the surface of the housing 1, a placement plate 102 fixedly connected to the inner wall of the housing 1, a partition plate 103 fixedly connected to the bottom of the placement plate 102, a collection area formed between one side of the partition plate 103 and the housing 1, an outlet 104 communicating with the collection area is opened on the surface of the housing 1, a drive assembly 3 is provided on one side of the housing 1, and a sampling assembly 2 is provided on the top of the placement plate 102. The sampling component 2 includes a first electric push rod 202 disposed on the top wall of the housing 1. The output shaft of the first electric push rod 202 is fixedly connected to a pressure plate 201. A sampling module is disposed on the top of the pressure plate 201. A through hole is opened on the surface of the pressure plate 201. A scraper 203 is disposed on one side of the bottom of the pressure plate 201 and is located below the pressure plate 201 and slidably connected to the surface of the pressure plate 201. A motor 204 is disposed on one side of the pressure plate 201. A threaded rod 205 is fixedly connected to the output shaft of the motor 204. The other end of the threaded rod 205 is rotatably connected to the surface of the pressure plate 201. One end of the scraper 203 is threadedly connected to the surface of the threaded rod 205, and the other end of the scraper 203 is slidably connected to the surface of the pressure plate 201.

[0021] The interior of the housing 1 can be exposed by moving the baffle 101 upward, which makes it convenient to place the sample to be tested. The sample to be tested is placed under the pressure plate 201, and the pressure plate 201 is moved downward by the first electric push rod 202. During this process, the sample can be squeezed to fix the sample. After the sample is compressed, the starting motor 204 drives the threaded rod 205 to rotate, which in turn moves the scraper 203 to scrape off the frost on the sample surface. This process reduces the difficulty of subsequent sampling caused by the frost and improves the purity of the sample.

[0022] like Figures 1-8 As shown, the sampling module includes a turntable 206 disposed above the pressure plate 201. The surface of the turntable 206 is provided with uniformly distributed mounting grooves. The inner wall of the mounting groove is provided with a guide groove 207, which is spirally arranged. A sampling cylinder 211 is slidably connected to the inner wall of the mounting groove. A slider 213 is fixedly connected to the surface of the sampling cylinder 211 and slidably connected to the inner wall of the guide groove 207.

[0023] The turntable 206 has evenly distributed second electric push rods 208 that correspond to the mounting slots. The output shaft of the second electric push rod 208 passes through the interior of the mounting slot and is rotatably connected to one end of the sampling cylinder 211. The sampling cylinder 211 has a through hole 212 that communicates with the mounting slot at one end near the second electric push rod 208.

[0024] The turntable 206 has an installation cavity 210 located between two installation slots. An air pump 209 is installed inside the installation cavity 210. The inner wall of the installation cavity 210 has two connecting channels that are connected to two adjacent installation slots respectively. The air pump 209 draws air in a clockwise direction through the connecting channels.

[0025] After the frost is scraped off, the sampling cylinder 211 can be moved down by activating the second electric push rod 208 at the bottom. During this process, the sampling cylinder 211 is rotated by the cooperation of the slider 213 and the guide groove 207, which facilitates the sampling cylinder 211 to sample the cold chain logistics samples to be tested. During the sampling process, the adjacent air pump 209 in the clockwise direction can draw air from the inside of the sampling cylinder 211 to form a negative pressure, thereby better adsorbing the sample inside the sampling cylinder 211. At the same time, the discharged air can be discharged through the adjacent mounting groove connected by the connecting channel. During this process, it can be injected into the inside of the sampling cylinder 211 through the through hole 212 opened on the sampling cylinder 211, so that the sample inside the sampling cylinder 211 can be pushed out better. Specifically, the surface of the baffle 101 is provided with a sampling slot, which makes it convenient for staff to take out the discharged samples. The sample storage container can be placed in the sampling slot to facilitate the collection of the discharged samples. Furthermore, the turntable 206 rotates counterclockwise; By rotating the turntable 206 counterclockwise, the purpose of sampling and sample discharge can be achieved during the sampling process, realizing the effect of continuous sampling. This effectively improves work efficiency in cold chain logistics environments where a large number of samples need to be collected for testing.

[0026] like Figures 1-8 As shown, the drive assembly 3 includes a motor 301 located below the placement plate 102 and on the side of the partition plate 103 away from the collection area. The output shaft of the motor 301 is fixedly connected to a drive shaft 307. A connecting shaft 306 is fixedly connected to one side of the turntable 206. One end of both the drive shaft 307 and the connecting shaft 306 passes through the housing 1 and is fixedly connected to a transmission wheel 308. A transmission belt 309 is provided on the surface of the transmission wheel 308. The two transmission wheels 308 are connected by transmission belt 309.

[0027] A rotating disk 302 located inside the collection area is fixedly connected to the surface of the drive shaft 307. A collection shell 303 is fixedly connected to the surface of the rotating disk 302 in a uniformly distributed manner and in equal number to the installation slot. A slag discharge groove is opened on the surface of the placement plate 102 and communicates with one of the collection shells 303. An outlet shell 304 communicating with the discharge outlet 104 is fixedly connected to the inner wall of the shell 1.

[0028] The inner bottom wall of the collection area is provided with evenly distributed nozzles 311, which are used for the discharge of disinfectant. The inner wall of the collection area is provided with drain holes 310 for the discharge of waste liquid.

[0029] An adjusting wheel 305 is provided on one side of the housing 1. The surface of the adjusting wheel 305 is in contact with the inner side of the transmission belt 309. A slide rod is fixedly connected to the surface of the adjusting wheel 305. The other end of the slide rod is slidably connected to the surface of the housing 1. A spring is fixedly connected between the adjusting wheel 305 and the surface of the housing 1.

[0030] A drying module 312 located in the collection area is embedded in one side of the housing 1.

[0031] By starting the motor 301, the drive shaft 307 connected to it can be driven to rotate clockwise. Specifically, each rotation angle is 90 degrees, and after each rotation is in place, it pauses for 30 seconds to carry out the sampling, sorting, and sample placement and removal operations. During the rotation of the drive shaft 307, the rotation of the turntable 206 can be achieved through the cooperation of the transmission belt 309 and the transmission wheel 308. At the same time, the rotation of the drive shaft 307 can drive the rotating disk 302 to rotate, thereby adjusting the position of the collection shell 303. The collection shell 303 can collect the frost scraped off by the scraper 203. The collected frost can be discharged through the through groove, the outlet shell 304 and the discharge port 104, which is convenient for individual collection. There is no need for staff to perform separate swab collection operations on the surface of the sample to be tested, which further improves work efficiency. The adjustment wheel 305, slide bar and spring are designed to ensure that the transmission belt 309 maintains good tension when the pressure plate 201 is adjusted to different heights, so that the transmission wheel 308 connected to the drive shaft 307 can be driven by the transmission belt 309 to rotate synchronously.

[0032] When the collection shell 303 moves to the bottom, it can spray disinfectant through the nozzle 311 to rinse and disinfect the inner wall of the collection shell 303. The disinfected waste liquid is discharged through the drain hole 310.

[0033] The drying module 312 uses a fan in conjunction with an electric heating tube to generate a heated airflow to dry the inner wall of the rinsed collection shell 303, which facilitates the subsequent collection of frost and avoids residual liquid from affecting the subsequent detection effect of frost.

[0034] Working principle: The interior of the housing 1 is exposed by the upward baffle 101, facilitating the placement of the sample to be tested. The sample is placed under the pressure plate 201, and the pressure plate 201 is moved downward by the first electric push rod 202. During this process, the sample is squeezed and fixed. After the sample is compressed, the starting motor 204 drives the threaded rod 205 to rotate, which in turn moves the scraper 203 to remove frost from the sample surface. This reduces the difficulty of subsequent sampling due to frost and improves the purity of the sample. After the frost is removed, the second electric push rod 208 at the bottom moves the sampling cylinder 211 downward. During this process, the cooperation between the slider 213 and the guide groove 207 rotates the sampling cylinder 211, facilitating the sampling of the cold chain logistics sample. By activating the adjacent air pump 209 in a clockwise direction, air can be drawn from inside the sampling cylinder 211, creating a negative pressure inside to better adsorb the sample inside the sampling cylinder 211. At the same time, the discharged air can be discharged through the adjacent mounting slot connected by the connecting channel. During this process, the air can be injected into the sampling cylinder 211 through the through hole 212, allowing the sample inside the sampling cylinder 211 to be pushed out more easily. The staff can place the sample storage container in the sampling slot to facilitate the collection of the discharged sample. Meanwhile, under the action of the drive component 3, the frost scraped off by the scraper 203 can be collected. The collected frost can be discharged through the through slot, the outlet shell 304 and the discharge port 104, which is convenient for separate collection. There is no need for the staff to perform separate swab collection on the surface of the sample to be tested, which further improves the work efficiency.
