Detailed Implementation

[0034] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0035] Example

[0036] like Figures 1 to 10As shown, a 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 inside the housing assembly 2. The air duct assembly 1 serves as the base support for the reagent tray structure, providing a heat exchange channel for the reagent tray assembly 3. The housing assembly 2 includes a reagent compartment 203 and a reagent compartment cover 201, which are connected by a hinge on a rear support frame 207. The reagent compartment 203 is surrounded by insulation material. The reagent tray assembly 3 includes a reagent bottle 319, a reagent bottle support 305 for fixing the reagent bottle 319, a tray base 308, and a transmission mechanism connected to the tray base 308. The reagent bottle support 305 is fixed to the tray base 308, and the transmission mechanism drives the tray base 308 and the reagent bottle support 305 to rotate about the center of the reagent bottle support 305.

[0037] like Figure 3 As shown, the transmission mechanism includes a motor 301, a first synchronous pulley 302, a synchronous belt 303, a second synchronous pulley 310, a first pinion 304, and a first 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 pinion 304. The first pinion 304 meshes with the first gear 309, and the first gear 309 is fixed below the tray base 308. The transmission mechanism drives the tray base 308 and the reagent bottle holder 305 to rotate about the center of the reagent bottle holder 305. When the motor 301 is working, it drives the synchronous belt 303 through the first synchronous pulley 302. The synchronous belt 303 drives the second synchronous pulley 310. The second synchronous pulley 310 coaxially drives the first pinion 304 to rotate. Since the first pinion 304 is meshed with the first large gear 309, it further drives the first large gear 309 to rotate, and finally drives the tray base 308 and the reagent bottle holder 305 to rotate together. When the reagent bottle holder 305 rotates, the inner ring holder 312 and the outer ring holder 311 located on the reagent bottle holder 305 rotate simultaneously about the center of the reagent bottle holder 305.

[0038] The reagent bottle holder 305 includes an inner ring holder 312 and an outer ring holder 311. The reagent bottles 319 on the inner ring holder 312 simultaneously rotate under the action of the transmission mechanism. The transmission mechanism also includes a second pinion 306 and a second large gear 307. The second large gear 307 is fixed to the bottom of the reagent bottle holder 305, and the second pinion 306 is fixed to the bottom of the inner ring holder 312 of the reagent bottle holder 305 via bearings. The second pinion 306 meshes with the second large gear 307. When the reagent bottle holder 305 rotates, the second large gear 307 fixed to its bottom also rotates accordingly. The second pinion 306 and the second large gear 307 perform planetary gear motion, where the sun gear is the second large gear 307 and the planetary gear is the second pinion 306. The bottom of each inner ring support 312 is provided with a bottle base support 322, which is connected to the second pinion 306 via a bearing. Each bottle base support 322 is provided with several pins 313, which engage with the limiting pin holes at the bottom of the reagent bottles placed on the inner ring support for positioning. The pins 313 cooperate with the limiting pin holes 321 to fix the reagent bottles 319 onto the inner ring support 312. Finally, when the reagent bottle support 305 rotates, the reagent bottles 319 on the inner ring support 312 will not only rotate with the reagent bottle support 305 but also rotate on their own axis.

[0039] like Figures 2 to 4 As shown, the inner ring support 312 and outer ring support 311 of the reagent bottle holder 305 are each provided with a plurality of slots 318 for accommodating and fixing the reagent bottles 319. In this embodiment, the outer ring support 311 has 16 slots 318 for fixing the reagent bottles 319, and the inner ring support 312 has 4 slots 318 for fixing the reagent bottles 319. The cross-section of the slot 318 is C-shaped and has a notch 317; each notch 317 is opened radially outward from the center of the disk of the reagent bottle holder 305. Figure 5 As shown, the reagent bottle 319 has a cap thread on the outside of the bottle mouth, which makes it easy to tighten the reagent bottle cap to prevent reagent evaporation; a limiting boss 316 is provided below the cap thread, which makes it easy to install the reagent bottle 319 onto the reagent bottle bracket 305.

[0040] like Figure 7 As shown, two fins 320 are symmetrically arranged on the inner side of the reagent bottle 319; when the reagent bottle 319 on the inner ring support 312 rotates, the reagent in the reagent bottle 319 can be effectively mixed.

[0041] like Figure 8As shown, the air duct assembly 1 includes a fan 101, an air duct 102, a base plate 103, and a cooling module 104. The fan 101 is installed at one end of the air duct 102 to dissipate heat generated by the cooling module 104 during operation; the cooling module 104 is installed at the other end to provide a continuous low-temperature condition for the reagent tray. The housing assembly 2 and the reagent tray assembly 3 are mounted on the top of the base plate 103. The base plate 103 also has several condensate drain holes 105, which allow condensate to drain from the bottom of the reagent tray and the bottom of the large reagent bottle in a timely manner.

[0042] like Figure 9 and 10 As shown, a reagent bottle barcode scanning window is provided on one side of the reagent compartment 203. A heating element is installed on the window for defogging, and a barcode scanner 205 is located outside the window. A large reagent bottle compartment 208 is located on the other side of the reagent compartment 203. A liquid level sensor 209 is installed on the large reagent bottle compartment 208, which is used to hold large reagent bottles. These large reagent bottles are used to hold sample diluents, a large-dose reagent required in the instrument's workflow. They require low-temperature storage and are too large to be placed in the reagent tray, so they are placed next to it. The liquid level sensor 209 monitors whether the liquid level in the large reagent bottle is too low. It is installed at the bottom side of the large reagent bottle compartment 208. When the liquid level in the large reagent bottle decreases to a certain value, the liquid level sensor 209 is triggered.

[0043] The reagent compartment cover 201 has two through holes 202, which correspond to the bottle openings of reagent bottles 319 on the inner ring support 312 and the outer ring support 311, respectively, to facilitate the insertion of other reagent needles into the reagent bottles 319 to retrieve reagents. The handle of the reagent compartment cover 201 is equipped with a magnetic block 206. When the reagent compartment cover 201 is closed, the magnetic block 206 is attracted to the top of the front support frame 204. The front support frame 204 is equipped with a sensor that can be used to detect whether the cover is closed.

[0044] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
