Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0029] Embodiment 1

[0030] Please see Figures 1-6 This embodiment provides a technical solution: a biological reagent reaction device, including: a tank 1, a tank cover 2, a scraping and collecting mechanism 3, and a stirring mechanism 4;

[0031] The bottom of the tank 1 has a liquid outlet, and the inside of the tank 1 has a cavity for holding the liquid medicine. The liquid outlet can be used for subsequent discharge of the liquid medicine. The lid 2 is set on the top of the tank 1 and is connected to the tank 1 by bolts around the perimeter. When the lid 2 is connected to the tank 1, it can achieve a sealing effect on the inside of the tank 1. When the lid 2 is unlocked and opened, it can inject the liquid medicine into the tank 1.

[0032] The scraping and collecting mechanism 3 is located at the bottom of the tank 1. The scraping and collecting mechanism 3 can quickly clean the residual medicine on the inner wall of the tank 1. The scraping and collecting mechanism 3 includes a scraper 301 located at the bottom of the tank 1. The size of the scraper 301 is adapted to the cavity reserved in the tank 1. A collection groove is opened above the scraper 301. The reserved collection groove can quickly collect the medicine on the inner wall of the tank 1 during subsequent cleaning. The collection groove has a hole with a cross-section in the middle, which can provide internal structure fixation and facilitate the subsequent entry and exit of medicine in the tank 1.

[0033] A connecting rod 302, welded above the scraper block 301, has an "L"-shaped cross-section and serves as a connection between structures. A bearing 303, welded to the other end of the connecting rod 302, secures the internal structure without affecting its rotation during the connection process. A connecting plate 304, welded inside the hole of the scraper block 301, has a "+" shape when viewed from above. The gap between the connecting plate 304 and the inner wall of the hole in the scraper block 301 allows for the flow of the medicine. The connecting plate 304 has a through hole inside, allowing the internal structure to move vertically. A circular tube 305, welded above the connecting plate 304, engages with the through hole of the connecting plate 304, providing greater stability to the internal structure during vertical movement.

[0034] The connecting rod 306 is connected to the connecting plate 304 and the inside of the circular tube 305 in a vertical sliding manner. During movement, the connecting rod 306 can drive the structure connected to the top end to move synchronously. The limiting block 307 welded at the bottom of the connecting rod 306 can prevent the connecting rod 306 from falling off during movement. The size of the limiting block 307 is greater than the through hole of the connecting plate 304. The baffle 308 welded at the top end of the connecting rod 306 can close the hole reserved for the scraping block 301 after the scraping block 301 is attached. The spring 309 sleeved on the circular tube 305 can drive the structure connected to one end to move through the elastic force of the spring 309.

[0035] The two ends of the spring 309 are welded to the outer walls of the connecting plate 304 and the baffle 308, respectively, which can drive the baffle 308 to move vertically downward, so that the baffle 308 is attached to the scraping block 301. The protrusion 310 welded to the middle of the inner bottom of the tank body 1 is located directly below the connecting rod 306. The protrusion 310 can extrude the connecting rod 306 above through its thickness, so that the connecting rod 306 moves vertically upward. The stirring mechanism 4 is arranged at the inner bottom of the tank cover 2. The stirring mechanism 4 can drive the liquid medicine in the tank body 1 to stir. The bottom end of the stirring mechanism 4 is connected to the scraping and collecting mechanism 3. During movement, the stirring mechanism 4 drives the scraping and collecting mechanism 3 to move synchronously on the inner wall of the tank body 1.

[0036] After the liquid medicine is delivered into the tank body 1, the tank cover 2 is connected and closed to the tank body 1 through bolts. When the inner wall of the tank body 1 needs to be cleaned after the liquid medicine in the tank body 1 is discharged through the bottom discharge port, the tank cover 2 is unlocked to drive the scraping and collecting mechanism 3 below the stirring mechanism 4 to move together. The scraping block 301 is connected to the stirring mechanism 4 through the bearing 303 on the connecting rod 302, so that the stirring mechanism 4 does not affect the rotating work during the stirring work. At this time, the connecting rod 306 below the baffle 308 in the scraping block 301 is no longer continuously extruded and moved vertically upward by the protrusion 310 below, so as to reset through the spring 309, thereby closing the liquid medicine flow hole reserved for the scraping block 301 through the movement of the baffle 308. When the scraping block 301 cleans the inner wall of the tank body 1, the residual liquid medicine will be stored above the scraping block 301.

[0037] Embodiment 2

[0038] Please refer to Figures 1-3 The embodiment provides a technical scheme: a biological reagent reaction device, comprising: a motor 401, a connecting shaft 402 and a blade 403.

[0039] The motor 401 is fixed on the outer wall of the tank cover 2, and is fixedly connected through bolts. The motor 401 can provide the structure on the output end to continuously rotate. The connecting shaft 402 connected with the output end of the motor 401 can provide the structure on the shaft to continuously rotate synchronously. The other end of the connecting shaft 402 is clamped and fixed in the bearing 303, so that the rotation of the connecting shaft 402 is not affected when fixedly connected. The blades 403 welded on the outer wall of the connecting shaft 402 can stir the liquid medicine placed in the tank body 1 during rotation.

[0040] The motor 401 is started to drive the connecting shaft 402 on the output end of the motor 401 to rotate. During the rotation of the connecting shaft 402, the blades 403 are driven to stir the liquid medicine in the tank body 1. The connecting shaft 402 is connected with the scraper 301 through the connecting rod 302 on the bearing 303, so that the connection with the scraper 301 is not affected during the rotation of the connecting shaft 402.

[0041] The implementation principle of the biological reagent reaction device is as follows:

[0042] Firstly, after the liquid medicine is delivered into the tank body 1, the tank cover 2 is connected and closed with the tank body 1 through bolts, and the liquid medicine in the tank body 1 is stirred through the stirring mechanism 4. When the liquid medicine in the tank body 1 is discharged through the bottom discharge port.

[0043] Secondly, the motor 401 is started to drive the connecting shaft 402 on the output end of the motor 401 to rotate. During the rotation of the connecting shaft 402, the blades 403 are driven to stir the liquid medicine in the tank body 1. The connecting shaft 402 is connected with the scraper 301 through the connecting rod 302 on the bearing 303, so that the connection with the scraper 301 is not affected during the rotation of the connecting shaft 402.

[0044] Finally, when the inner wall of the tank body 1 needs to be cleaned, the stirring mechanism 4 below the tank cover 2 is moved together by unlocking the tank cover 2. The scraper 301 is connected with the stirring mechanism 4 through the bearing 303 on the connecting rod 302, so that the stirring mechanism 4 can rotate during the stirring work. At this time, the connecting rod 306 below the baffle 308 in the scraper 301 is no longer continuously pressed and moved vertically upward by the lower protrusion 310, so that the liquid medicine flow hole reserved in the scraper 301 is closed by the movement of the baffle 308. When the scraper 301 cleans the inner wall of the tank body 1, the residual liquid medicine is stored above the scraper 301.

[0045] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics thereof. The presently disclosed embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
