Detailed implementation manners

[0040] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0041] Embodiment

[0042] Such as Figures 1 to 11As shown in the figure, a reagent tray structure, the reagent tray structure includes an air duct assembly 1, a housing assembly 2, and a reagent tray assembly 3; the housing assembly 2 is disposed on the air duct assembly 1, and the reagent tray assembly 3 is disposed within the housing assembly 2; the air duct assembly 1 is the base support of the reagent tray structure, providing a heat exchange channel for the reagent tray assembly 3; the housing assembly 2 includes a reagent storage body 203 and a reagent storage cover 201, and the reagent storage body 203 and the reagent storage cover 201 are connected by a hinge provided on the rear support frame 207; the reagent storage body 203 is wrapped with a heat insulating material around; the reagent tray assembly 3 includes reagent bottles 319, a reagent bottle support 305 for fixing the reagent bottles 319, a tray bottom support 308, and a transmission mechanism connected to the tray bottom support 308; the reagent bottle support 305 is fixed on the tray bottom support 308, and the transmission mechanism drives the tray bottom support 308 and the reagent bottle support 305 to rotate about the center of the reagent bottle support 305; the reagent bottle support 305 is composed of a plurality of inner ring supports 312 and outer ring supports 311, and the reagent bottles 319 on each of the inner ring supports 312 simultaneously rotate under the action of the transmission mechanism; the rotation speed of the reagent bottles 319 on the inner ring supports 312 is greater than the rotation speed of the reagent bottle support 305.

[0043] In one embodiment, as Figure 3 shown, the transmission mechanism includes a motor 301, a first synchronous pulley 302, a synchronous belt 303, a second synchronous pulley 310, a first small gear 304, and a first large gear 309. The motor 301 is connected to the second synchronous pulley 310 through the first synchronous pulley 302 and the synchronous belt 303. The second synchronous pulley 310 coaxially drives the first small gear 304. The first small gear 304 meshes with the first large gear 309, and the first large gear 309 is fixed below the tray bottom support 308; the transmission mechanism drives the tray bottom support 308 and the reagent bottle support 305 to rotate about the center of the reagent bottle support 305. When the motor 301 operates, it drives the synchronous belt 303 through the first synchronous pulley 302, the synchronous belt 303 drives the second synchronous pulley 310, and the second synchronous pulley 310 coaxially drives the first small gear 304 to rotate. Since the first small gear 304 and the first large gear 309 are in a meshing relationship, further driving the first large gear 309 to rotate, ultimately driving the tray bottom support 308 and the reagent bottle support 305 to rotate together; when the reagent bottle support 305 rotates, the inner ring supports 312 and the outer ring supports 311 on the reagent bottle support 305 simultaneously rotate about the center of the reagent bottle support 305.

[0044] As Figure 4 and 5As shown, the transmission mechanism further includes a second large gear 307 and a plurality of second small gears 306. The second large gear 307 is installed on the base cover 325, and the base cover 325 is installed on the base 326. The second large gear 307, the base cover 325, and the base 326 are relatively stationary. Each of the second small gears 306 is installed at the bottom of the inner ring bracket 312 in the reagent bottle bracket 305 through a bearing, and each of the second small gears 306 meshes with the second large gear 307. When the reagent bottle bracket 305 rotates, the second small gear 306 and the second large gear 307 perform a planetary gear motion. At this time, the sun gear is the second large gear 307, and the planetary gear is the second small gear 306. A bottle bottom support 322 is provided at the bottom of each of the inner ring brackets 312. The bottle bottom support 322 is connected to the second small gear 306 through a bearing. A plurality of pin shafts 313 are provided on the bottle bottom support 322. The pin shafts 313 are inserted and positioned with the limit pin holes 321 at the bottom of the reagent bottle placed on the inner ring bracket 312, and the reagent bottle 319 is fixed on the inner ring bracket 312. Finally, when the reagent bottle bracket 305 rotates, the reagent bottle 319 on the inner ring bracket 312 will not only rotate with the reagent bottle bracket 305 but also rotate itself.

[0045] As Figures 2 to 5 As shown, an inner ring slot 318 for accommodating the reagent bottle 319 is provided on the inner ring bracket 312, and an outer ring slot 323 for accommodating the reagent bottle 319 is provided on the outer ring bracket 311. The cross-section of each slot is C-shaped, and each has a slot opening 317. Each slot opening 317 is opened from the center of the disc of the reagent bottle bracket along the radial outward direction. Two longitudinal ridges 314 are provided on the outer side of the reagent bottle 319. The inner distance between the two longitudinal ridges 314 is greater than the barcode width, which is convenient for pasting the barcode. The outer distance between the two longitudinal ridges 314 is slightly smaller than the slot opening 317 distance of the outer ring slot 323. When the two longitudinal ridges 314 are located at the slot opening 317 of the outer ring slot 323, the outer reagent bottle 319 is installed in place. Through the limiting effect of the two longitudinal ridges 314, it can be ensured that the barcode on the outer reagent bottle 319 always faces outward, ensuring that the barcode can be scanned when the outer reagent bottle passes through the barcode scanner. A cap thread is provided on the outer side of the bottle mouth of the reagent bottle 319, which is convenient for screwing on the reagent bottle cap to prevent reagent volatilization. A limiting boss 316 is provided below the cap thread, which is convenient for installing the reagent bottle 319 onto the reagent bottle bracket 305.

[0046] The aperture of the inner ring slot hole 318 is larger than that of the outer ring slot hole 323; a snap ring 315 is provided at the upper end of the inner ring slot hole 318. Two longitudinal ridges 314 are provided on the outer side of the reagent bottle. The inner spacing between the two longitudinal ridges 314 is larger than the bar code width, facilitating the pasting of the bar code; the outer spacing between the two longitudinal ridges 314 is slightly smaller than the opening spacing of the snap ring 315; the snap ring 315 is located between the longitudinal ridge 314 on the outer side of the reagent bottle and the limiting boss 316 on the outer side of the reagent bottle mouth; the aperture of the inner ring slot hole 318 is larger than the cylindrical aperture swept by the outermost edges of the two longitudinal ridges 314 on the reagent bottle during rotation. Due to the limiting effect of the snap ring 315 on the longitudinal ridge 314 on the reagent bottle, it can be ensured that the reagent bottle 319 can only be taken out upward when the inner ring reagent bottle rotates to the position where the longitudinal ridge 314 is within the notch 317 of the inner ring slot hole 318; similarly, when installing the inner ring reagent bottle, it can only be achieved when the reagent bottle holder rotates to a specific position.

[0047] The number of the inner ring holders 312 is 1 to 10, and each inner ring holder 312 can accommodate a reagent bottle 319. Each of the inner ring holders 312 is distributed on a circumferential surface, and the included angle between two adjacent inner ring holders 312 is an integer multiple of 36 degrees. The transmission ratio of the second small gear 306 to the second large gear 307 is 1:5 to 20. For example: in one of the embodiments, the number of teeth of the second small gear 306 is 10, the number of teeth of the second large gear 307 is 100, and their transmission ratio is 1:10. At this time, when the reagent bottle holder 305 rotates one circle, the reagent bottle 319 (the second small gear 306) in the inner ring holder rotates ten circles, and the rotation angle of the reagent bottle holder 305 corresponding to each rotation of the reagent bottle in the inner ring holder is 36°. As Figure 2 shown, when the number of inner ring reagent bottles 319 is 4, the angle between adjacent reagent bottles is 72° or 144°, both of which are integer multiples of 36°. Therefore, the postures of the inner ring reagent bottles at the same position are always the same. When installing, if the bar codes of all inner ring reagent bottles face the bar code scanner along the center of the disc, then when all the reagent bottles rotate to this position, the bar codes on the reagent bottles still face the bar code scanner.

[0048] Therefore, through the design of an appropriate transmission ratio and the position of the inner ring reagent bottle, it can be ensured that during the rotation of the inner ring reagent bottle following the reagent bottle holder 305, the bar code of the reagent bottle 319 can always be exposed in the scanning path of the scanner at the scanning position of the bar code scanner.

[0049] As Figure 8 shown, two fins 320 are symmetrically provided on the inner side of the reagent bottle 319; when the reagent bottle 319 on the inner ring holder 312 rotates, the reagent in the reagent bottle 319 can be effectively mixed. As Figure 5As shown, a radiator 324 is provided in the middle of the reagent bottle holder 305 on the bottom tray 308.

[0050] As Figure 9 shown, the air duct assembly 1 includes a fan 101, an air duct 102, a bottom plate 103, and a refrigeration module 104. One end of the air duct 102 is provided with the fan 101 for discharging the heat generated during the operation of the refrigeration module 104; the other end is provided with the refrigeration module 104 to provide continuous low-temperature conditions for the reagent tray. Above the bottom plate 103 is used to set the housing assembly 2 and the reagent tray assembly 3. A number of condensate discharge holes 105 are also provided on the bottom plate 103, and the condensate discharge holes 105 can enable the condensate at the bottom of the reagent tray and the bottom of the large reagent bottle to be discharged in time.

[0051] As Figure 10 and 11 shown, a reagent bottle barcode scanning window is provided on one side of the reagent storage body 203. A heating sheet is installed on the reagent bottle barcode scanning window for defogging the window, and a barcode scanner 205 is provided outside the window. On the other side of the reagent storage body 203 is provided a large reagent bottle storage 208. A liquid level sensor 209 is provided on the large reagent bottle storage 208, and the large reagent bottle storage 208 is used to accommodate large reagent bottles. The large reagent bottle is used to load sample diluent, which is a large-dose reagent required in the instrument process. Its storage environment also requires low temperature. Its volume is relatively large and it is not suitable to be installed in the reagent tray, so it is installed beside the reagent tray. The function of the liquid level sensor 209 is to monitor whether the liquid level in the large reagent bottle is too low. It is installed at the bottom side of the large reagent bottle storage 208. When the liquid in the large reagent bottle decreases to a certain value, the liquid level sensor 209 will be triggered.

[0052] Two through holes 202 are provided on the reagent storage cover 201, and the through holes 202 are respectively used to correspond to the bottle mouth positions of the reagent bottles 319 on the inner ring support 312 and the outer ring support 311, facilitating other reagent needles to penetrate into the reagent bottles 319 to take reagents. A magnetic block 206 is installed at the handle position of the reagent storage cover 201. After the reagent storage cover 201 is closed, the magnetic block 206 is attracted to the top of the front support frame 204. A sensor is provided on the front support frame 204, which can be used to detect whether the cover is closed.

[0053] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those of ordinary skill in the relevant technical field can also make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention shall be defined by the claims.
