Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] Please refer to Figures 1 to 5 The utility model provides a reagent detection assembly 100, including a reagent kit 11 and a detection box 12; wherein the reagent kit 11 includes a detachably connected reagent tube 111 and a reagent cover 112, wherein a receiving chamber 1111 with an opening on one side is formed inside the reagent tube 111, wherein the receiving chamber 1111 is used to place reagents, and the reagent cover 112 is used to block the opening of the receiving chamber 1111; the detection box 12 includes a detection tube 121, a detection cover 123 and a test strip 125, wherein the detection cover 123 is movably connected to one end of the detection tube 121, and one end of the test strip 125 is fixedly connected to the detection cover 123 and extends into In the detection tube 121, one end of the detection tube 121 away from the detection cover 123 is detachably connected to the detection box 12, and the detection cover 123 has a movement direction that drives the test strip 125 to extend into or away from the accommodating chamber 1111; the reagent detection component 100 has a packaging state and a detection state. When the reagent detection component 100 is in the packaging state, the reagent cover 112 is connected to the reagent tube 111, and the reagent tube 111 is disconnected from the detection tube 121. When the reagent detection component 100 is in the detection state, the reagent cover 112 is disconnected from the reagent tube 111, and the reagent tube 111 is connected to the detection tube 121.

[0026] The reagent in the reagent tube 111 is used to react with the sample to be tested, and the test strip 125 in the test box 12 is used to contact the reacted reagent to display the reaction result. By setting a movable detection cover 123, the test strip 125 can be manually and actively contacted with the reacted reagent, which can ensure that the reagent is evenly distributed on the test strip, thereby improving the convenience of operation and the accuracy of detection.

[0027] Please refer to Figure 1 When the reagent detection component 100 is in the detection state, the detection cover 123 keeps the connecting space between the reagent tube 111 and the detection tube 121 sealed at all times. When in the packaging state, the reagent cover 112 can effectively seal the reagent tube 111, thereby effectively isolating the interference from the external environment, reducing the detection error, and improving the detection reliability of the reagent detection component 100.

[0028] Please refer to Figure 3 and Figure 4In this embodiment, at least two grooves 124 are formed on the outer circumference of the detection cover 123, and at least two protrusions 122 are formed on the inner wall of the detection tube 121, and each protrusion 122 is plugged and matched with each groove 124 in a one-to-one correspondence. When the detection cover 123 is inserted into the detection tube 121, the groove 124 provides a track for the movement of the detection cover 123, plays a guiding role, and facilitates the user to press the detection cover 123 to contact the test strip 125 with the post-reaction reagent. At the same time, the design of the groove 124 and the protrusion 122 makes the connection between the detection cover 123 and the detection tube 121 more stable, ensuring that the detection cover 123 remains stable during the detection process, avoiding errors that may be caused by shaking, thereby ensuring the stability and reliability of the reagent detection process.

[0029] Specifically, the detection cover 123 includes a cover body 1231, a plug end and an abutment end 1233, the plug end is plugged with the detection tube 121, the diameter of the abutment end 1233 is larger than the diameter of the plug end, and the abutment end 1233 is used to abut the end surface of the detection tube 121, each groove 124 is provided on the outer peripheral surface of the cover body 1231, and each groove 124 includes a first section 1241, a second section 1242 and a third section 1243 which are connected in sequence, and the second section 1241 is connected to the detection tube 121. The two ends of 242 are connected to the first section 1241 and the third section 1243 respectively. The first section 1241 extends to the plug-in end and is provided with an inlet for plugging with the corresponding protrusion 122. The third section 1243 extends to the abutment end 1233. When the protrusion 122 is in the first section 1241, the test strip 125 is not in the accommodating cavity 1111. When the protrusion 122 is in the third section 1243, the test strip 125 partially extends into the accommodating cavity 1111.

[0030] The introduction port of the first section 1241 can be chamfered to facilitate the protrusion 122 to enter the first section 1241. After the first section 1241 is introduced, it enters the second section 1242. The protrusion 122 moves to the third section 1243 and contacts the abutment end 1233. The abutment end 1233 provides a stable supporting plane, which effectively prevents the protrusion 122 from escaping from the groove 124, thereby improving the stability of the fit between the detection cover 123 and the detection tube 121.

[0031] The matching state between the detection cover 123 and the detection tube 121 includes a detection preparation state and a detection start state. When in the detection preparation state, the detection cover 123 and the detection tube 121 are plugged and assembled, the protrusion 122 is in the first section 1241, and the test strip 125 is at a certain distance from the reagent in the accommodating chamber 1111. When in the detection start state, the detection cover 123 further extends into the detection tube 121, the protrusion 122 is in the third section 1243, and the test strip 125 enters the accommodating chamber 1111 to contact the reacted reagent.

[0032] The second section 1242 and the first section 1241 and the third section 1243 can be tilted to effectively separate the detection preparation state and the detection start state, that is, when the protrusion 122 enters the first section 1241, the tilted second section 1242 effectively prevents the protrusion 122 from continuing to slide into the second section 1242. When the user rotates the protrusion 122 to pass through the second section 1242 and enter the third section 1243, the detection cover 123 switches from the detection preparation state to the detection start state, and the test strip 125 enters the accommodating cavity 1111.

[0033] The guiding effect of the multi-segment groove 124 can ensure a more precise fit between the protrusion 122 and the groove 124, reducing improper fit caused by operational deviation. When the detection cover 123 is rotated until the groove 124 of the detection tube 121 is fully matched with the protrusion 122, the existence of the angle can increase additional friction. Such a fit can form a "self-locking" effect to ensure the stability of the detection during use. The correct installation of the detection cover 123 requires accurate fit, and the setting of the angle can serve as a directional guide to reduce errors made by the operator during installation and improve user friendliness.

[0034] The angle structure can usually provide a stronger fastening force than a straight line. Such a structural design helps to make the detection cover 123 more firmly on the detection tube 121, reducing reagent leakage or contamination caused by improper operation. In addition, by accurately guiding the detection cover 123 into place, the consistency and repeatability of the detection process are ensured, which is very important for ensuring the accuracy of the detection results.

[0035] Please refer to Figure 2 Specifically, the plug-in end of the detection cover 123 is provided with a socket 1234, and the test strip 125 is plugged into the socket 1234 to achieve the plug-in matching of the test strip 125 and the detection cover 123. The cross-sectional shape of the socket 1234 can be square or other polygonal, which effectively prevents the test strip 125 from rotating during the rotation of the detection cover 123, reduces the detection error, and improves the detection accuracy of the reagent detection component 100. At the same time, the detection tube 121 of the transparent material facilitates the observation of the detection result of the test strip 125.

[0036] In this embodiment, the second section 1242 is extended along the circumference of the detection cover 123, and the extension direction of the first section 1241 and the extension direction of the third section 1243 are both perpendicular to the extension direction of the second section 1242. The first section 1241 and the third section 1243 perpendicular to the second section 1242 make the rotation path more intuitive and easy to understand. Combined with the transparent detection tube 121, the user can more directly see the correct installation position of the detection cover 123. The vertical design helps to simplify the rotation operation between the detection cover 123 and the detection tube 121, because users usually tend to move straight up and down, and this design can reduce errors during operation.

[0037] Furthermore, at least one blocking portion 1244 is convexly provided at the connection between the second section 1242 and the first section 1241 and the third section 1243, and each blocking portion 1244 is smoothly transitioned with the inner wall of the groove 124. The convex blocking portion 1244 provides clear position feedback. When the user pushes the convex block 122 to move in the first section 1241 and contacts the blocking portion 1244, the diameter of the groove 124 decreases, and the user feels resistance, which prompts the user to reach the connection between the first section 1241 and the second section 1242, and can rotate to enter the second section 1242. At the same time, the blocking portion 1244 can also remind the user to pass through the second section 1242 and enter the third section 1243, and the detection box 12 is switched from the ready-to-detect state to the start-detection state.

[0038] The blocking portion 1244 provides stable support for the relative position of the fixed protrusion 122 in the groove 124, thereby stabilizing the position of the detection cover 123, especially when moving the reagent detection assembly 100, improving the stability and reliability of the overall structure. The smoothly transitioned blocking portion 1244 is conducive to the user applying pressure to rotate, reducing the resistance and friction when the detection cover 123 rotates, making the rotation action smoother and better for the user.

[0039] In some embodiments, the multiple protrusions 122 in the detection tube 121 can be symmetrically arranged on the same horizontal plane, and the multiple protrusions 122 must reach the connection between the first section 1241 and the second section 1242 to rotate, that is, the detection cover 123 needs to be kept in a horizontal state to rotate, thereby improving the connection strength and sealing effect between the detection cover 123 and the detection tube 121.

[0040] Please refer to Figure 5 In the present embodiment, the reagent cover 112 includes a limiting portion 1122 which abuts against the main body 1121 and the open end surface of the reagent reagent box 11, the area of ​​the limiting portion 1122 is larger than the opening area of ​​the accommodating cavity 1111, and the limiting portion 1122 is provided with a grabbing end 1123 extending along the circumferential direction of the main body 1121, and the distance between the edge surface of the grabbing end 1123 and the outer surface of the main body 1121 is larger than the distance between the other edge surfaces of the limiting portion 1122 and the outer surface of the main body 1121.

[0041] The limiting portion 1122 realizes the seal between the reagent cover 112 and the reagent tube 111, effectively preventing the internal reagent from being contaminated. The grabbing end 1123 provided on the limiting portion 1122 has a larger protruding area. The user can easily remove and install the reagent cover 112 by grabbing the grabbing end 1123 without the aid of additional tools, thereby improving the convenience of use. The user can more easily open or close the reagent cover 112 without the need for additional tools or force. During the detection operation, the user can complete the opening and closing of the reagent cover 112 more quickly and accurately, thereby improving the efficiency and reliability of the experiment.

[0042] In one embodiment, the reagent tube 111 is provided with a dripping channel with the accommodating chamber 1111, and the dripping channel has a dripping inlet which is in the same plane as the opening of the accommodating chamber 1111, and the diameter of the dripping inlet is smaller than the opening diameter of the accommodating chamber 1111. The grabbing end 1123 of the reagent cover 112 may be protrudingly provided with a plug portion, which is plugged into and fits with the dripping inlet, and a fold is provided between the grabbing end 1123 and other parts of the reagent cover 112 to realize the flipping function of the grabbing end 1123 and the reagent cover 112.

[0043] When the reagent in the reagent tube 111 needs to be added to the sample to be tested, the plug and the dripping port are separated by flipping the grabbing end 1123, and the opening of the accommodating chamber 1111 does not need to be separated from the reagent cover 112, so that the reaction between the sample to be tested and the reagent can be achieved. After the reaction between the sample to be tested and the reagent is completed, the reagent cover 112 and the reagent tube 111 are separated, and the reagent tube 111 is connected to the test tube 121. Such an arrangement effectively avoids the situation where the reagent and the sample to be tested are contaminated, improves the stability of the reaction, and further improves the accuracy of the test results of the subsequent test strip 125.

[0044] In some embodiments, the periphery of the reagent cover 112 extending into the accommodating cavity 1111 may be provided with a silicone seal, and the plug-in portion between the detection tube 121 and the reagent tube 111, and the plug-in portion between the detection tube 121 and the detection cover 123 may be provided with a silicone seal to improve the sealing performance of the reagent detection assembly 100. The detachable connection between the detection tube 121 and the reagent tube 111 may be a threaded connection, a snap connection, a latch connection, etc., which is not limited here.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
