[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0032] like Figures 1 to 5 As shown, an embodiment of the present invention provides an EP tube low-temperature storage chamber that is convenient for rehydration, which is generally placed in a corresponding square box-shaped device. The square box-shaped device is provided with an opening cover for rehydrating the EP tube low-temperature storage or cleaning and replacing the pipeline when the opening cover is open. Specifically, the EP tube low-temperature storage chamber involved in this embodiment includes: a low-temperature storage chamber 1 and an EP tube storage chamber 2, wherein the low-temperature storage chamber 1 includes a low-temperature chamber 11, the low-temperature chamber 11 is provided with a side opening 113, and the back side 112 of the low-temperature chamber 11 is provided with a linear bearing 12; the EP tube storage chamber 2 is movably arranged in the low-temperature chamber 11, and the EP tube storage chamber 2 includes an EP tube seat 21 for placing the EP tube 22, and a guide rod 26 connecting the EP tube seat 21 and the linear bearing 12, the guide rod 26 is arranged through the linear bearing 12, and the guide rod 26 performs linear motion along the linear bearing 12 to enable the EP tube seat 21 to be pushed into or pulled out of the low-temperature chamber 11 along the side opening 113. In this way, the low-temperature storage chamber can be withdrawn, which is convenient for fluid replenishment or cleaning and replacement of pipelines, thereby reducing the occupied space of the overall device. In addition, the EP tube 22 is also provided with a one-way valve 23 for liquid replenishment and a liquid extraction tube 24. In this way, when the reagent is extracted from the liquid extraction tube 24, the one-way valve 23 allows air to enter the EP tube, thus ensuring smooth extraction of the reagent. The one-way valve 23 can also prevent the reagent from volatilizing.

[0033] In one embodiment of the present invention, two linear bearings 12 are provided, and correspondingly, two guide rods 26 are also provided, and each guide rod 26 passes through a corresponding linear bearing 12. In this way, the EP tube storage chamber 2 is supported and guided by the cooperation of the linear bearings 12 and the guide rods 26 during the pushing and pulling process, so as to ensure the stability and smoothness of the pushing and pulling of the EP tube storage chamber 2.

[0034] In one embodiment of the present invention, a baffle 27 is provided at the end of the guide rod 26 near the linear bearing 12 to limit the extension travel of the cryogenic chamber 11.

The ceramic pads 15 are installed on the bottom of the cryogenic chamber 11 to prevent the temperature from being transferred to the entire machine.

[0039] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the EP tube seat 21 includes a tube seat body 211 and a cover plate adapted to the size of the side opening 113. The side wall of the tube seat body 211 is wavy and adapted to the shape of the outer wall of the EP tube 22. The tube seat body 211 is provided with a guide rod connecting seat for connecting the guide rod 26.

[0040] In one embodiment of the present invention, a second heat-insulating cotton 25 is provided on the surface of the cover plate for blocking heat exchange.

[0041] In one embodiment of the present invention, Figure 6 As shown, the EP tube low-temperature storage chamber further includes a heat dissipation assembly 3, which includes a cooling fin 33 and a heat dissipation fin 31 connected to the cooling fin 33. The cooling fin 33 is mounted on the heat dissipation fin 31 via a fixing bracket 34. The heat dissipation assembly further includes a heat dissipation fan 32 mounted on the heat dissipation fin 31.

[0042] In one embodiment of the present invention, the cryogenic storage chamber 1 comprises a cryogenic chamber 11, linear bearings 12, a temperature sensor 13, a first thermal insulation layer 14, and a ceramic pad 15. The cryogenic chamber 11 is a machined aluminum component, with five exterior surfaces coated with a layer of thermal insulation 14 to isolate it from high temperatures. Two linear bearings 12 are secured to the cryogenic chamber 11 by screws, and a temperature sensor 13 is mounted on the chamber 11 to monitor the internal temperature. The ceramic pad 15 is installed at the bottom of the chamber 11 to prevent heat transfer to the entire unit.

The EP tube seat 21 fits tightly with the EP tube 22 to maintain good heat conduction. Two holes are opened on the EP tube 22, one connected to the one-way valve 23 and the other connected to the liquid extraction tube 24. When the reagent is extracted from the liquid extraction tube 24, the one-way valve 23 allows air to enter the EP tube, thus ensuring that the reagent is extracted smoothly. The one-way valve 23 can also prevent the reagent from volatilizing. The guide rod 26 and the baffle 27 cooperate with the linear bearing 12 to allow the EP tube storage chamber 2 to be freely pushed in and pulled out.

[0044] In one embodiment of the present invention, the heat dissipation assembly 3 comprises heat dissipation fins 31, a heat dissipation fan 32, a cooling plate 33 and a fixing bracket 34. The heat dissipation assembly 3 is mainly used to dissipate heat from the low-temperature storage chamber to maintain a low temperature.

[0045] In one embodiment of the present invention, when the user replenishes fluid or replaces or cleans the EP tube and pipeline, he first pulls out the EP tube storage chamber, then pulls out the one-way valve 23, and adds the corresponding reagent into the EP tube. After it is full, he inserts the one-way valve 23 and then pushes the EP tube storage chamber in.

[0046] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
