[0002] Reagent testing can be used to conduct qualitative and quantitative analysis of different substances, help determine the composition and properties of substances, or to detect and analyze the presence and concentration of target substances, as well as to conduct chemical reactions and synthesis to promote the experimental process. Reagent testing is of great significance for ensuring product quality, promoting scientific research, and improving human health.

[0003] During the reagent detection process, the detection reagent and the reaction reagent need to be shaken in the reagent tube to fully mix them. At present, in the reagent detection with fewer detection items, the reagents are mixed by manual hand-held shaking. The patent document with the prior art publication number CN116593268A provides a chemical reagent detection device.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Example 1

[0043] Reference Figure 1-8 , which is the first embodiment of the present invention, provides a reagent detection device, which includes a fixed seat 1, a support seat 2 is provided outside the fixed seat 1, the support seat 2 is driven by a motor 3 inside the fixed seat 1, and a plurality of reagent mixing mechanisms 4 are installed on the support seat 2 in a circular shape with equal intervals.

[0044] The reagent mixing mechanism 4 includes a first rotating sleeve 401 rotatably connected to the support seat 2, the end of the rotating shaft of the first rotating sleeve 401 is connected to the support frame 403, one end of the support frame 403 is transmission-connected to a reciprocating screw rod 404, the reciprocating screw rod 404 is rotatably connected to the support seat 2, and a second rotating sleeve 406 is rotatably provided inside the first rotating sleeve 401, and the second rotating sleeve 406 is used to clamp the reagent tube.

[0045] The lower end of the fixed seat 1 is connected to a connecting ring 5, and an arc-shaped rack 501 is fixedly connected to the connecting ring 5. The first transmission gear 407 connected to the lower end of the reciprocating screw 404 cooperates with the arc-shaped rack 501 for transmission. The upper end of the fixed seat 1 is connected to a fixed gear ring 6, and the second rotating sleeve 406 cooperates with the fixed gear ring 6 for transmission.

[0046] In the above technical solution, the reagent tube can be placed in the second rotating sleeve 406. When the motor 3 drives the support frame 2 to rotate, the reagent tube revolves around the fixed seat 1. When the first transmission gear 407 is engaged with the arc rack 501, the reciprocating screw 404 can rotate. The reciprocating screw 404 drives the support frame 403 to rise and rotate the first rotating sleeve 401, so that a certain angle is set between the reagent tube and the fixed seat 1. At the same time, the fixed gear ring 6 drives the second rotating sleeve 406 to rotate, so that the reagent tube rotates in an inclined state, thereby effectively mixing the solution.

[0047] The fixing seat 1 comprises a bottom plate 101 , a cylinder 102 is fixedly connected to the bottom plate 101 , and the supporting seat 2 is sleeved on the cylinder 102 .

[0048] A gear groove 201 is provided in the support base 2 , a driving gear 301 is fixedly connected to the output end of the motor 3 , and a plurality of driven gears 302 are meshedly connected between the gear groove 201 and the driving gear 301 .

[0049] In the above technical solution, the driven gear 302 is rotatably connected in the cylinder 102, and a through hole is opened in the cylinder 102 at the driven gear 302. One end of the driven gear 302 passes through the through hole and is meshed with the gear groove 201. When the motor 3 rotates, the driven gear 302 is driven to rotate through the driving gear 301, and the driven gear 302 cooperates with the gear groove 201 to drive the support seat 2 to rotate.

[0050] The support frame 403 is in a Y-shaped structure. Two connecting rods 402 are hinged on the upper end of the support frame 403. The connecting rods 402 are fixedly connected to the rotating shaft of the first rotating sleeve 401. The other end of the support frame 403 is hinged with a sliding sleeve 405, which is slidably connected to the reciprocating screw rod 404.

[0051] In the above technical solution, when the first transmission gear 407 is meshed with the arc-shaped rack 501, it drives the reciprocating screw 404 to rotate a certain number of circles, so that the sliding sleeve 405 rises, and the first rotating sleeve 401 is driven to rotate through the support frame 404 and the connecting rod 402, so that a certain angle can be set between the reagent tube and the fixed seat 1, so that the reagent tube is in an inclined state.

[0052] An arc-shaped tooth groove 408 is formed on the outer side of the second rotating sleeve 406 , and a second transmission gear 409 is meshedly connected to one side of the arc-shaped tooth groove 408 . The second transmission gear 409 is meshedly connected to the fixed gear ring 6 .

[0053] In the above technical solution, the second transmission gear 409 is rotatably connected to the support seat 2. When the first rotating sleeve 401 rotates, it drives the second rotating sleeve 406 to rotate synchronously, but the arc-shaped tooth groove 408 always keeps meshing with the second transmission gear 409. Therefore, when the support seat 2 rotates, the second transmission gear 409 meshes with the fixed gear ring 6 to produce self-rotation, and drives the second rotating sleeve 406 and the reagent tube connected thereto to rotate. The reagent tube rotates rapidly in an inclined state, so that solutions at different heights in the reagent tube can be quickly mixed.

[0054] It can be understood that the diameter of the fixed gear ring 6 is larger than the diameter of the second rotating sleeve 406, so that the support base 2 can rotate slowly on the fixed base 1 while the reagent tube can rotate quickly. When the support base 2 rotates slowly, the centrifugal force can be avoided from affecting the exchange of solutions.

[0055] A plurality of clamping plates 410 are arranged in an annular shape and at equal intervals in the second rotating sleeve 406 , and a second spring 411 is elastically connected between the clamping plates 410 and the second rotating sleeve 406 .

[0056] In the above technical solution, the inner side of the clamping plate 410 is set to be a concave arc surface, and each clamping plate 410 cooperates with the second spring 411 to adaptively clamp the reagent tube, thereby improving the convenience of connecting and taking the reagent tube.

[0057] There are at least two second springs 411 between a clamping plate 410 and the second rotating sleeve 406 , and they are evenly spaced vertically. Under the action of the multiple second springs 411 , the clamping plate 410 can stably clamp the reagent tube.

[0058] During use, the reagent tube is inserted into the second rotating sleeve 406, and the reagent tube is clamped by the second spring 411 and the clamping plate 410, and the motor 3 is started. When the motor 3 rotates, the driven gear 302 is driven to rotate through the active gear 301, and the driven gear 302 cooperates with the gear groove 201 to drive the support seat 2 to rotate. When the first transmission gear 407 is engaged with the arc rack 501, the reciprocating screw rod 404 can be rotated a certain number of times, so that the sliding sleeve 405 rises, and the first rotating sleeve 401 is driven to rotate through the support frame 404 and the connecting rod 402, so that the reagent tube and the fixed seat 1 are set at a certain angle, so that the reagent tube is in an inclined state, and at the same time, the second transmission gear 409 is engaged with the fixed gear ring 6 to produce rotation, and drives the second rotating sleeve 406 and the reagent tube connected thereto to rotate. The reagent tube rotates rapidly in the inclined state, and solutions at different heights in the reagent tube can be quickly mixed.

[0059] Example 2

[0060] Reference Figure 7-8, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that a plurality of protrusions 502 are fixedly provided on the connecting ring 5 in a circular shape with equal intervals, and the first transmission gear 407 is in sliding contact with the protrusions 502 .

[0061] The connecting ring 5 is slidably disposed on the fixing seat 1 . A plurality of first bolts 503 are threadedly connected to the connecting ring 5 . One end of the first bolt 503 is in abutment with the fixing seat 1 .

[0062] In the above technical solution, the height of the top surface of the protrusion 502 is higher than the height of the bottom surface of the first transmission gear 407. When the protrusion 502 at the bottom of the first transmission gear 407 contacts, it can drive the support seat 2 to rise. When the contact of the protrusion 502 at the bottom of the first transmission gear 407 is cancelled, the support seat 2 drops, thereby allowing the reagent tube to rotate in an inclined state while receiving the vibration transmission of the support seat 2, thereby further enhancing the exchange and mixing efficiency between solutions.

[0063] In addition, the connecting ring 5 can be moved up and down on the fixed seat 1, and the connecting ring 5 can be limited by the first bolt 503. When the connecting ring 5 is adjusted upward, the height of the protrusion 502 can be adjusted, thereby increasing the vibration amplitude of the connecting seat 2. In addition, when the connecting ring 5 is adjusted downward, the protrusion 502 can be prevented from contacting the first transmission gear 407, thereby canceling the vibration effect, and when it is adjusted downward again, the meshing between the arc-shaped rack 501 and the first transmission gear 407 can be canceled, thereby canceling the adjustment of the inclination state of the reagent tube. In this way, it is possible to select a mixing method based on the concentration and capacity of the solution in the reagent tube, thereby enriching the applicable scenarios.

[0064] A rotating ring 202 is provided above the support seat 2, the rotating ring 202 is rotatably connected to the fixed seat 1, and a plurality of sliding rods 203 are fixedly connected to the rotating ring 202, the sliding rods 203 are slidably connected to the support seat 2, and a first spring 204 is elastically connected between the sliding rods 203 and the support seat 2.

[0065] In the above technical solution, the first spring 204 is sleeved on the slide rod 203. When the support seat 2 is acted upon by the protrusion 502 and the first transmission gear 407, the first spring 204 cooperates with the slide rod 203 to make the support seat 2 elastically shake, thereby reducing the vibration energy transmitted to the reagent tube and increasing the vibration frequency, thereby further improving the solution mixing effect.

[0066] The remaining structures are the same as those of Example 1.

[0067] Example 3

[0068] Reference Figure 6, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a connecting frame 601 is fixedly connected to the fixed gear ring 6, and the connecting frame 601 is slidably connected to the fixed seat 1, and a second bolt 602 is rotatably connected to the connecting frame 601, and the second bolt 602 is threadedly connected to the fixed seat 1.

[0069] In the above technical solution, rotating the second bolt 602 can drive the fixed gear ring 6 to move downward, so that the fixed gear ring 6 cancels the engagement with the second transmission gear 409, thereby canceling the self-rotation of the reagent tube, so that the lifting and lowering adjustment with the connecting ring 5 can further enrich the mixing method of the solution and improve the applicable scenarios.

[0070] The remaining structure is the same as that of Example 2.

[0071] Example 4

[0072] As a fourth embodiment of the present invention, there is provided: a method for using a reagent detection device, comprising the following steps:

[0073] S1, insert the reagent tube into the second rotating sleeve 406, and clamp the reagent tube through the cooperation of the second spring 411 and the clamping plate 410;

[0074] S2, start the motor 301 to drive the support base 2 to rotate, and the first transmission gear 407 meshes with the arc-shaped rack 501 to drive the reciprocating screw rod 404 to rotate, so that the sliding sleeve 405 rises and cooperates with the support frame 403 to drive the first rotating sleeve 401 to rotate, and at the same time, the second transmission gear 409 meshes with the fixed gear ring 6 to drive the second rotating sleeve 406 to rotate;

[0075] S3, the first transmission gear 407 intermittently contacts with the protrusion 502 to drive the support base 2 to vibrate up and down;

[0076] S4. The reagent tube is tilted under the drive of the first rotating sleeve 401, and rotates under the drive of the second rotating sleeve 406, so that the solution is turned over in the reagent tube to complete mixing, and the mixing is accelerated under the action of vibration.

[0077] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
