[0025] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).
[0026] This application provides a chemiluminescence analyzer substrate cooling device 100, please refer to Figure 1-7 The chemiluminescence analyzer substrate refrigeration device 100 includes a refrigeration chamber 110 , a substrate container 120 and a refrigeration module 130 .
[0027] Please refer to Figure 1-4 and Figure 7 The refrigeration cavity 110 has a support member 111, a substrate container 120 is disposed within the refrigeration cavity 110, and a refrigeration module 130 is disposed adjacent to the circumference of the refrigeration cavity 110 to cool the refrigeration cavity 110. The substrate container 120 includes a container body 121, a container lid assembly 122, and a support frame 129. The container body 121 has a first opening 1211 and is used to hold a substrate solution. The container lid assembly 122 includes a container lid 1221, a waterproof breathable member 1224, a first sealing member 126, a second sealing member 127, and a straw 128. The container lid 1221 is sealed against the first opening 1211 and has a first through-hole 1222 and a second through-hole 1223. The waterproof breathable member 1224 is sealed against the first through-hole 1222 via the first sealing member 126, allowing gas to circulate within the refrigeration cavity 110 and the container body 121 through the waterproof breathable member 1224. A pipette 128 is sealed in the second through-hole 1223 by a second sealing member 127. Pipette 128 is used to aspirate substrate from the chemiluminescence analyzer. Support frame 129 includes a connected mounting end 1291 and a hanging end 1293. Mounting end 1291 is fixedly mounted on container lid 1221 and defines a third through-hole 1292. Third through-hole 1292 faces second through-hole 1223, and pipette 128 passes through third through-hole 1292. Second sealing member 127 is pressed between second and third through-holes 1223 and 1292 by mounting end 1291. Hanging end 1293 hangs from support member 111.
[0028] In this application, the container lid 1221 is sealed at the first opening 1211, the waterproof breathable member 1224 is sealed at the first through hole 1222 via the first seal 126, and the straw 128 is sealed at the second through hole 1223 via the second seal 127. The waterproof breathable member 1224 can prevent condensed water from entering the container body 121, but gas can flow between the refrigeration cavity 110 and the container body 121. Therefore, the container lid assembly 122 in this application can prevent condensed water from entering the container body 121 and contaminating the substrate, and has good sealing performance. In addition, the second seal 127 is pressed between the second through hole 1223 and the third through hole 1292 by the mounting end 1291 of the support frame 129 and the container lid 1221. The setting of the mounting end 1291 not only fixes the support frame 129 to the container lid 1221, but also seals the second seal 127 between the second through hole 1223 and the third through hole 1292.
[0029] Specifically, the first sealing member 126 and the second sealing member 127 are both sealing rings. The container lid 1221 can be sealed against the first opening 1211 via another sealing ring. The container lid 1221 and the container body 121 have an interference fit, which is simpler to operate than a threaded fit and improves operational efficiency. The waterproof breathable member 1224 is a waterproof breathable valve. The mounting end 1291 is secured to the container lid 1221 via screws.
[0030] Please refer to Figure 5-6 The waterproof, breathable member 1224 includes an air inlet cover 1225, a waterproof, breathable membrane 1226, and a connector 1227. The connector 1227 has a gas channel 1228, with the waterproof, breathable membrane 1226 disposed at one end of the gas channel 1228. The air inlet cover 1225 is connected to the connector 1227, covering the end of the gas channel 1228 where the waterproof, breathable membrane 1226 is disposed. The air inlet cover 1225 has an air inlet hole 1229, which communicates with the gas channel 1228. The end of the connector 1227, facing away from the air inlet cover 1225, is detachably connected to the sidewall of the first channel. When the air inlet cover 1225 is attached to the connector 1227, a gap exists between the top of the air inlet cover 1225 and the end of the connector 1227 where the waterproof, breathable membrane 1226 is disposed.
[0031] The air inlet 1229 allows the air in the refrigeration cavity 110 to enter the gas channel 1228, and the waterproof breathable membrane 1226 can allow the air to pass through while preventing the water from passing through.
[0032] Please refer to Figure 6 The air inlet hole 1229 is provided on the circumference of the air inlet cover 1225. The provision of the gap space is to facilitate the air inlet hole 1229 to be provided on the circumference of the air inlet cover 1225 and to communicate with the gas channel 1228.
[0033] The air inlet hole 1229 is set on the side of the air inlet cover 1225. Even if the condensed water temporarily covers the air inlet hole 1229, under the action of gravity, the condensed water will flow downward from the side of the air inlet cover 1225, and will not hinder the gas from flowing from the air inlet hole 1229 through the gas channel 1228 and finally flowing to the container body 121.
[0034] The waterproof breathable membrane 1226 is a polymer waterproof material, and its base material is usually polytetrafluoroethylene (PTFE) or polyurethane (TPU), etc. These materials have a microporous structure, which enables the membrane to block moisture and liquids while allowing gas (such as water vapor) to pass through, thereby maintaining breathability.
[0035] Please refer to Figure 4 The air inlet cover 1225 is exposed from the container cover 1221 on the side of the container cover 1221 away from the container body 121, and the distance between the air inlet hole 1229 and the container cover 1221 is greater than 5 mm.
[0036] According to tests, even if condensed water accumulates on the upper surface of the container lid 1221, it will not cover the air inlet 1229. This is because condensed water within 5 mm will slide down to the bottom wall of the refrigeration chamber 110 due to its own gravity. Therefore, only air can flow from the air inlet 1229 through the gas channel 1228 and then into the interior of the container body 121.
[0037] In the present application, the aperture of the air inlet 1229 is d, and d satisfies: 0.5 mm ≤ d ≤ 1 mm.
[0038] Controlling the aperture of the air inlet hole 1229 can further reduce the possibility of condensed water entering the air inlet hole 1229.
[0039] Please refer to Figure 4 The connecting piece 1227 is screwed into the side wall of the first through hole 1222 .
[0040] On the one hand, the waterproof breathable member 1224 can be stably fixed on the container cover 1221 , and on the other hand, the waterproof breathable member 1224 can be easily disassembled.
[0041] Please refer to Figure 4 The container cover assembly 122 further includes a straw fixing member 123, which is disposed on a side of the container cover 1221 facing away from the container body 121. The straw fixing member 123 has a through-hole 1231, through which a portion of the straw 128 passes and is fixed. More specifically, as Figure 3-4The container cover assembly 122 also includes an inverted cone 124 and a fastening joint 125. The inverted cone 124 and the fastening joint 125 are sequentially arranged in the through-hole 1231 along the axial direction of the through-hole 1231, and are arranged to enclose the straw 128. The fastening joint 125 abuts against the inverted cone 124 to fix the straw 128 in the through-hole 1231.
[0042] The fastening joint 125 can tighten the inverted cone 124 into the through-hole 1231 , thereby fixing the straw 128 in the through-hole 1231 , preventing the straw 128 from being pulled out and affecting the substrate supply.
[0043] Please refer to Figure 7 The support member 111 is tiltedly disposed on the side wall of the refrigeration cavity 110 so that the condensed liquid falls along the support member 111 .
[0044] The tilted arrangement of the support member 111 allows condensed water formed by the heat exchange to flow smoothly down the support member 111 under the action of gravity, preventing the condensed water from accumulating on the surface of the support member 111 and being carried away when the container body 121 is replaced. In addition, the support member 111 can be suspended by the hanging end 1293. When the container body 121 is replaced, the container cover 1221 can be temporarily hung on the support member 111, preventing the container cover assembly 122 from being contaminated while also facilitating the replacement of the substrate solution. The support member 111 and the hanging end 1293 form a line-surface fit, reducing the contact area between them, thereby reducing the friction generated during relative movement.
[0045] In this application, please refer to Figure 7 The side of the refrigeration cavity 110 has a second opening 112, which is used to replace the container body 121. Specifically, the second opening 112 faces the access door of the chemiluminescence analyzer, which can facilitate the access of the container body 121.
[0046] Please refer to Figure 2 The refrigeration module 130 consists of a semiconductor refrigeration plate, a copper tube, a heat sink and a fan. The semiconductor refrigeration plate cools on one side and dissipates heat on the other side. There are two heat sinks. The fan is arranged between the two heat sinks. The heat dissipation surface conducts heat to the heat sink through the copper tube. The fan can further dissipate heat, and the refrigeration surface can provide continuous cooling.
[0047] Also, please refer to Figure 7A drainage hole 113 is provided at the lowest point of the bottom wall of the refrigeration cavity 110, and a uniform downwardly inclined inclined surface 114 is provided on the bottom wall of the refrigeration cavity, and the inclined surface 114 converges at the drainage hole 113. The gathering structure of the inclined surface 114 is conducive to draining the condensed water into the drainage hole 113, effectively preventing backflow and high-speed drainage. At the same time, the production cost is low and the economic benefit is good. Furthermore, the drainage hole 113 is a threaded hole, and the elbow 115 is screwed into the drainage hole 113. The elbow 115 can be connected to a water pump. By controlling the water pump through the switch, the condensed water can be quickly discharged to prevent the excessive accumulation of condensed water from flowing into the interior of the instrument, causing a short circuit and contamination of the interior of the instrument.
[0048] Please refer to Figure 7 The rear side wall of the refrigeration chamber 110 has a limiting groove 116 for the substrate container 120 to enter. The limiting groove 116 has the function of limiting the left and right swing of the substrate container 120, ensuring the stability and accuracy of the substrate container 120 during assembly, while effectively improving operational efficiency. Specifically, one end of the bottom of the container body 121 abuts against the inclined surface 114 at the bottom of the limiting groove 116, and the other end abuts against the inclined surface 114 near the second opening 112 of the container body 121. Since these two inclined surfaces 114 are inclined and converge at the drainage hole 113, the bottom of the container body 121 is in two-line contact with the inclined surface 114. Then, the bottom of the container body 121 is suspended above the drainage hole 113, and will not block the drainage hole 113, allowing for efficient drainage.
[0049] The entire refrigeration chamber 110 is made of aluminum alloy, which has good thermal conductivity, is easy to process, and has good economic benefits. The outer surface of the refrigeration chamber 110 is adhered with thermal insulation foam 140. A temperature sensor is also installed on the outside of the refrigeration chamber 110 to monitor the temperature environment inside the refrigeration chamber 110.
[0050] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
