[0039] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of the present application.

[0040] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] In the description of this application, it is necessary to explain that, unless otherwise clearly specified and limited, the terms "install", "set", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or connected through an intermediate medium. For ordinary technicians in this field, the above-mentioned specific meanings belonging to this application can be connected according to specific circumstances.

[0042] In the prior art, in order to reduce the damage to the instrument caused by the overflow of the reaction cup, a downward extending skirt and a gradually expanding downward extending skirt are usually used on the reaction cup, and the optical base is provided with a protruding structure assembled with the skirt. The function of the above-mentioned skirt is to guide the splashed liquid or guide the flow direction of the overflowed liquid, so that the splashed or overflowed liquid will not flow along the cup wall into the inside of the detection component.

[0043] However, the inner part of the skirt must have a certain depth to cooperate with the protruding structure on the optical base to achieve the function, making the structure of the existing reaction cup installed on the optical base relatively complex and using more materials. Since the reaction cup is a consumable material, the relatively complex structure of the reaction cup increases the consumption of materials.

[0044] In some implementations of the prior art, the limiting ribs inside the skirt of the reaction cup rely on the notch of the optical base to achieve positioning and foolproofing. In order to achieve a better reaction effect, the reaction cup needs to be relatively tightly matched with the heating element inside the optical base to improve the heating efficiency. The relatively tight fit of the existing heating element for the reaction cup also plays a positioning role. In the prior art, when the reaction cup is assembled on the optical base, the dual positioning of the optical base and the heating component is not conducive to the positioning and installation of the reaction cup.

[0045] In some implementations of the prior art, when there is liquid overflow or splashing at the mouth of the reaction cup, the liquid will still flow into the interior of the optical module along the inner surface of the skirt, or due to misoperation, for example, when there is residual liquid in the reaction cup and the reaction cup is taken out due to operations such as replacing the reaction cup, the connection between the drain port at the bottom of the reaction cup and the drain pipeline will be disconnected during the process of taking out the reaction cup. The residual liquid in the reaction cup will flow into the interior of the optical module as the reaction cup is taken out, causing damage to the components inside the optical module. The optical module has poor waterproofness and low reliability.

[0046] In summary, the present application provides an optical module and a specific protein analyzer, which solve the problems existing in the above-mentioned prior art through a technical solution formed by features including a waterproof structure of the optical base of the optical module, a drainage structure inside the optical module, and a fool-proof structure for positioning the heating component or the optical base relative to a single part of the reaction cup.

[0047] See also Figures 1 to 12 The present invention provides an optical module, comprising: an optical base 1 and a reaction cup 2, wherein the optical base 1 is provided with an insertion hole 12; the reaction cup 2 is used to be plugged into the insertion hole 12 so that the reaction cup 2 is inserted into the optical base 1; a flange 7 is provided on the outer wall of the reaction cup 2, and the flange 7 is arranged around the outer wall of the reaction cup 2; when the reaction cup 2 is inserted into the optical base 1, the flange 7 is located at the periphery of the insertion hole 12; the lower surface of the flange 7 is provided with an inwardly recessed interrupting groove 9.

[0048] In the present application, the optical module is applied to a specific protein analyzer. The testing principle of the specific protein analyzer can adopt nephelometry.

[0049] Combination Figure 1The optical module further includes: a light receiving element 3 and a light transmitter 5. The light transmitter 5 may be a laser, and the light receiving element 3 may be a photoelectric sensor. Figures 2-3 As shown, the reaction cup 2 includes a cylindrical section 6 and a flow guide section 10, which are connected in sequence. The cup mouth of the reaction cup 2 is opened on one side of the cylindrical section 6. A flange 7 is extended in the horizontal direction at the intersection of the cylindrical section 6 and the outer wall of the flow guide section 10. An inwardly concave flow-blocking groove 9 is designed at the lower surface of the flange 7 near the outer edge of the flange 7. Specifically, the flange 7 is an annular structure, and the flow-blocking groove 9 is an annular groove on the flange 7. In the present application, the structure of the flange 7 and the flow-blocking groove 9 is not specifically set, and it can be realized that when the reaction cup 2 overflows, the liquid is guided to flow in a direction away from the inside of the optical base 1, and even if the liquid flows to the lower surface of the flange 7, the structure of the flow-blocking groove 9 can intercept the liquid, so that the liquid converges at the edge of the flange 7 on the side of the flow-blocking groove 9 away from the center of the reaction cup 2, and the structure of the function of no longer flowing in the direction of the inside of the optical module is within the protection scope of the present application.

[0050] When liquid overflows from the mouth of the reaction cup 2 and flows downward along the outer wall of the reaction cup 2, and when it passes through the cylindrical section 6 and reaches the flange 7, the liquid will flow along the upper surface of the flange 7 to the outer edge of the flange 7, and then continue to flow downward. In the prior art, when the liquid flows to the outer edge of the lower surface of the flange 7, and the liquid flow rate is relatively high, the liquid will vertically break away from the outer edge of the lower surface of the flange 7 and fall downward; when the liquid flow rate is relatively low, the liquid will converge along the outer edge of the lower surface of the flange 7 toward the inner edge of the lower surface of the flange 7, reach the outer wall of the guide section 10, and finally flow into the optical module along the outer wall of the reaction cup 2. However, due to the upward concave effect of the stop groove 9 of the present application, that is, the stop groove 9 is a groove formed by the reverse concave in the direction opposite to gravity, the liquid cannot flow along the groove wall of the stop groove 9 and in the opposite direction of gravity, and thus the liquid is restricted by the stop groove 9 and continuously accumulates between the stop groove 9 and the outer edge of the lower surface of the flange 7. When a certain amount is reached, the liquid separates from the flange 7 due to the action of gravity and falls vertically, thereby reducing the damage of the liquid to the optical devices of the optical module when the reaction cup 2 overflows, helping to improve the waterproofness of the optical module, and thereby improving the reliability of the specific protein analyzer in which the optical module is located.

[0051] In order to further prevent liquid from entering the interior of the optical module when the reaction cup 2 overflows or leaks, in an exemplary embodiment, an annular boss 11 is provided on the optical base 1, and the inner wall of the annular boss 11 is configured to enclose part of the insertion hole 12; when the reaction cup 2 is inserted into the optical base 1, the annular boss 11 is located below the flange 7, and the distance between the outermost side wall of the annular boss 11 and the center line of the reaction cup 2 is a first distance L1, and the distance between the side wall of the interrupter groove 9 closest to the center line of the reaction cup 2 and the center line of the reaction cup 2 is a second distance L2, and the first distance L1 is smaller than the second distance L2. Figure 4 As shown, in the present application, when the reaction cup 2 is inserted into the optical base 1, the annular boss 11 is located below the flange 7 with a gap. The first distance L1 is smaller than the second distance L2, and when the liquid at the outer edge of the flange 7 falls and falls onto the upper surface of the optical base 1, the liquid will not flow into the interior of the optical base 1 through the insertion port of the reaction cup 2.

[0052] In order to further improve the waterproofness of the optical base 1, Figures 5 to 7 As shown, in an exemplary embodiment, the optical base 1 is provided with a first stopper 13 and a light receiving element 3, the light receiving element is provided on one side of the optical base 1, the first stopper 13 is provided at the periphery of the annular boss 11; the first stopper 13 is provided between the annular boss 11 and the light receiving element 3; when the reaction cup 2 is inserted into the optical base 1, the first stopper 13 is provided at the periphery of the flange 7. In the present application, the first stopper 13 is provided at the periphery of the annular boss 11 protruding from the optical base 1, the first stopper 13 can be specifically a convex edge, and the first stopper 13 is provided at the periphery of the flange 7, so that the liquid falling from the outer edge of the flange 7 falls between the protruding annular boss 11 and the first stopper 13, and prevents the liquid from flowing forward along the upper surface of the optical base 1 to the position of the light receiving element 3. In other embodiments, the first blocking member 13 may also be a recessed portion, a groove structure, etc., which is lower than the top surface 17 of the optical base 1, so that the liquid can flow in the first blocking member 13 to limit the flow direction of the liquid.

[0053] In order to further improve the waterproofness of the optical module, in an exemplary embodiment, a second blocking member 15 is provided on the optical base 1, and the second blocking member 15 is located between the annular boss 11 and the light receiving member 3. The first blocking member 13 and the annular boss 11 are provided on the top surface 17 of the optical base 1, and the second blocking member 15 is provided on the side surface 18 of the optical base 1. The top surface 17 of the optical base 1 is adjacent to the side surface 18 of the optical base 1. The end of the first blocking member 13 close to the second blocking member 15 is the first end of the first blocking member 13, and the end of the second blocking member 15 close to the first blocking member 13 is the first end of the second blocking member 15. The first end of the first blocking member 13 and the first end of the second blocking member 15 are staggered, and the distance between the first end of the first blocking member 13 and the light receiving member 3 is greater than the distance between the first end of the second blocking member 15 and the light receiving member 3. In the present application, the optical base 1 includes a top surface 17 and a side surface 18, and the side surface 18 includes at least a set of oppositely arranged left side surface and right side surface. Among them, a second blocking member 15 is provided on the right side surface, which is used to limit the flow of liquid to the light receiving element 3. The second blocking member 15 can be a convex edge. When the reaction cup 2 overflows and the liquid flows to the outer surface of the optical base 1, the first blocking member 13 is a first-layer blocking structure, and the second blocking member 15 is a second-layer blocking structure. The second blocking member 15 on the right side surface is staggered by a certain distance from the first end of the first blocking member 13 on the top surface 17 of the optical base 1 close to the light receiving element 3 to form a misalignment, so as to ensure that the liquid flows from the side away from the light receiving element 3 when flowing from the top surface 17 of the optical base 1 through the right side surface. In other embodiments, the second blocking member 15 can also be a recessed portion, a groove structure, etc., which is lower than the side surface 18 of the optical base 1, so that the liquid can flow in the first blocking member 13 to limit the flow direction of the liquid.

[0054] In one embodiment, a third blocking member 16 is provided on the left side of the optical base 1. The third blocking member 16 is formed by the first blocking member 13 extending downward along the left side. The third blocking member 16 is used to limit the flow of liquid toward the light receiving element 3. The liquid flows down along the left side of the optical base 1 under the action of gravity. When the reaction cup 2 overflows and the liquid flows to the outer surface of the optical base 1, the third blocking member 16 is a third-layer blocking structure. Through the three-layer blocking structure, the liquid flowing to the top surface 17 of the optical base 1 is blocked from flowing toward the light receiving element 3 from multiple directions.

[0055] In an exemplary embodiment, a first guide surface 14 is provided on one side of the side surface 18 of the optical base 1 connected to the top surface 17 of the optical base 1. In the present application, the first guide surface 14 is provided on the upper edge of the side surface 18, and when the liquid flows down from the top surface 17 of the optical base 1 toward the right side surface of the optical base 1, the liquid flows downward along the surface of the right side surface after being guided by the first guide surface 14.

[0056] In order to meet the reaction conditions, the reaction cup 2 needs to be temperature controlled accordingly to achieve appropriate reaction conditions. In an exemplary embodiment, the optical module further includes a heating component 4, which is disposed in the optical base 1. The inner wall of the heating component 4 surrounds and forms part of the insertion hole 12. At least one positioning groove is provided on the heating component 4 or the optical base 1; the reaction cup 2 is provided with a positioning rib that cooperates with the at least one positioning groove; a drainage hole is provided at the bottom of the heating component 4 and / or the bottom of the optical base 1, and the drainage hole is connected to the insertion hole 12. Figures 8 to 10 As shown, the heating component 4 is used to heat the reaction cup 2. In the present application, the outer side surface 18 of the heating component 4 is close to the inner wall of the optical base 1. The positioning groove includes a first positioning groove 19 and a second positioning groove 20 arranged on the heating component 4, and the first positioning groove 19 and the second positioning groove 20 are arranged opposite to each other. Specifically, the first positioning groove 19 and the second positioning groove 20 are arranged 180 degrees apart. In a preferred embodiment, a first drainage hole 21 and a second drainage hole 22 are respectively arranged at the bottom of the heating component 4 and / or the optical base 1 facing the first positioning groove 19 and the second positioning groove 20. The above arrangement can be used for the case where the liquid overflowing or leaking from the reaction cup 2 enters the interior of the optical module when the reaction cup 2 overflows, or when the liquid leaks due to misoperation or other factors, the liquid can also flow out of the optical module through the drainage hole to prevent damage to the electronic device. The drainage hole arranged opposite to the positioning groove makes it easier for the liquid flowing into the optical module along the positioning groove to quickly flow out from the drainage hole, effectively reducing the accumulation of liquid inside the optical module. In the present application, the number and size of the positioning grooves, positioning ribs, and drainage holes are not limited and can be set as needed.

[0057] In an exemplary embodiment, when the reaction cup 2 is inserted into the optical base 1, a first gap 31 exists between the reaction cup 2 and the inner wall of the optical base 1. In the present application, since the outer side surface 18 of the heating component 4 is in close contact with the inner wall of the optical base 1, the first gap 31 is a gap between the reaction cup 2 and the inner wall of the optical base 1 located above the heating component 4.

[0058] The reaction cup 2 includes a first light-transmitting surface 27, a second light-transmitting surface 28 and a positioning surface 26. The first light-transmitting surface 27 and the second light-transmitting surface 28 are arranged opposite to each other. The positioning surface 26 is arranged between the first light-transmitting surface 27 and the second light-transmitting surface 28. The positioning surface 26 cooperates with the insertion hole 12. When the reaction cup 2 is inserted into the optical base 1, a second gap 32 exists between the positioning surface 26 of the reaction cup 2 and the part of the insertion hole 12 formed by the inner wall of the optical base 1. The second gap 32 is larger than the first gap 31. The matching part 30 (see FIG. 31 ) between the positioning surface 26 of the reaction cup 2 and the optical base 1 Figure 2 and hereinafter) a second gap 32. In the present application, the reaction cup 2 is provided with two opposite first light-transmitting surfaces 27 and a second light-transmitting surface 28. In a direction perpendicular to the first light-transmitting surface 27 and the second light-transmitting surface 28, the outer wall of the reaction cup 2 is provided with a first positioning rib 24 and a second positioning rib 25. When the reaction cup 2 is inserted into the optical base 1, the positioning surface 26 on the outer side of the reaction cup 2 cooperates with the partial insertion hole 12 surrounded by the inner wall of the heating component 4 to realize the main positioning of the reaction cup 2, and the first positioning rib 24 and the second positioning rib 25 on the reaction cup 2 cooperate with the first positioning groove 19 and the second positioning groove 20 in the partial insertion hole 12 surrounded by the inner wall of the heating component 4 to realize the positioning of the reaction cup 2 in the rotation direction around its center line, thereby facilitating the laser emitted by the light emitter 5 to pass through the first light-transmitting surface 27 and the second light-transmitting surface 28 and be received by the light receiving element 3.

[0059] Combination Figure 2 , the positioning and foolproofing of the reaction cup 2 is achieved by the cooperation of the heating component 4 and the reaction cup 2. The reaction cup 2 is a consumable and needs to be replaced regularly. In order to facilitate replacement, a certain gap needs to be left when the reaction cup 2 cooperates with the heating component 4 to facilitate taking and placing. When the reaction cup 2 is inserted into the partial insertion hole 12 formed by the inner wall of the heating component 4, a relatively small third gap 33 is designed between the reaction cup 2 and the inner wall of the heating component 4, which is convenient for the heating component 4 to transfer heat and position the reaction cup 2. The gap between the inner wall of the optical base 1 located above the heating component 4 and the positioning surface 26 of the outer wall of the reaction cup 2 is relatively large and is not used for positioning, wherein the second gap 32 is larger than the third gap 33. The inner wall of the annular boss 11 is set as a conical structure 29, and the inner wall of the upper part of the heating component 4 is a matching part 30. The conical structure 29 and the matching part 30 constitute the pre-guide of the reaction cup 2 during the insertion of the optical base 1, and the relatively large second gap 32 is set to facilitate the loading and unloading of the reaction cup 2.

[0060] In a preferred embodiment, the first light-transmitting surface 27 and the second light-transmitting surface 28 are located lower than the positioning surface 26 of the outer wall of the reaction cup 2, so that the light-transmitting surface will not be scratched when the reaction cup 2 is installed, thereby affecting the detection result.

[0061] In an exemplary embodiment, a marking structure 23 is provided on the flange 7, and the position of the marking structure 23 corresponds to the position of one of the first light-transmitting surface 27 and the second light-transmitting surface 28. In the present application, a marking structure 23 is provided on one side of the flange 7 in a direction corresponding to one of the light-transmitting surfaces, so that when the reaction cup 2 is installed, it can be installed in a unified direction, and the influence of the difference between the two light-transmitting surfaces of the reaction cup 2 caused by the manufacturing error of the reaction cup 2 mold on the detection result can be avoided.

[0062] In an exemplary embodiment, a second guide surface 8 is provided on the side of the flange 7 away from the center line of the reaction cup 2. In the present application, the second guide surface 8 is designed at the edge of the flange 7. When liquid overflows from the mouth of the reaction cup 2 and flows downward along the outer wall of the reaction cup 2, when the liquid passes through the cylindrical segment 6 and reaches the flange 7, the liquid flows along the upper surface of the flange 7 to the second guide surface 8 of the flange 7, and continues to flow downward after being guided by the second guide surface 8.

[0063] One aspect of an embodiment of the utility model provides a specific protein analyzer, including: the optical module as described above.

[0064] This application has at least the following beneficial effects:

[0065] (1) The setting of the flow cut-off groove 9 can prevent the optical module from overflowing and splashing in a relatively economical manner; the relatively simple and small structure of the reaction cup 2 can prevent the reaction cup 2 from overflowing and splashing liquid from flowing along the outer wall of the reaction cup 2 from the gap between the insertion hole 12 of the optical base 1 and the reaction cup 2 to the inner wall of the optical module, thereby simplifying the production mold of the reaction cup 2, reducing the material of the reaction cup 2 as a consumable, and reducing resource waste.

[0066] (2) The first blocking member 13, the second blocking member 15, the third blocking member 16 and other flow limiting structures arranged on the outside of the optical base 1, as well as the flow guiding structure of the first guide member, and the flange 7 and the second guide surface 8 arranged on the reaction cup 2 enable the liquid to flow down according to the predetermined designed position, thereby preventing the liquid from flowing toward the light receiving element and thus avoiding damage to the electronic components of the optical module; and since the liquid flows down according to the position and direction designed in the present application scheme, it is also beneficial to the arrangement of other components adjacent to the optical module inside the specific protein analyzer and the related waterproof design, thereby improving the reliability of the instrument.

[0067] (3) A drainage hole is provided inside the optical module. Even if liquid flows into the optical module, the liquid can be discharged in time through the drainage hole, thereby avoiding the expansion of the damage caused by liquid accidentally flowing into the optical module. The liquid flowing into the optical module can effectively avoid the corrosion of the internal electrical and gas components and the short circuit of the electrical and gas connections that damages the corresponding control unit. The solution of the present application is conducive to improving the reliability of the optical module, and further improving the reliability of the specific protein analyzer.

[0068] (4) The positioning and fool-proofing structure of the reaction cup 2 is realized by the cooperation between a single part of the heating component 4 and the reaction cup 2 or by the cooperation between a single part of the optical base 1 and the reaction cup 2, which can greatly reduce the requirements for the manufacturing accuracy of the parts and the requirements for the assembly accuracy, effectively reduce the processing cost, and reduce the production difficulty.
