Description

Technical Field

[0001] The invention relates to the technical field of biological detection, in particular to an acetic acid content determination kit with an oscillating structure. Background Art

[0002] Acetic acid is the main component of vinegar and is widely distributed in nature. For example, it exists mainly in the form of esters in fruits or vegetable oils, and in the form of free acid in animal tissues, excrement and blood. The existing acetic acid content determination mainly uses high performance liquid chromatography for detection. The refractive index of acetic acid is different from that of the required mobile phase, and it can be detected using a differential refractive index detector. Phenolphthalein indicator solution and sodium hydroxide titrant are usually added during the determination process, and fusion-assisted determination is performed by shaking, mixing, etc.

[0003] The invention with announcement number CN115970551A discloses a test kit that can automatically oscillate and mix reagents. It adopts a new structural design, so that the test kit is provided with an auxiliary reagent oscillation and mixing structure, which can avoid the precipitation and separation of some components in the reagent, and the test kit is provided with a reagent bottle locking and limiting structure, so that the reagent bottle can be assembled in the test kit more stably.

[0004] The invention with announcement number CN116139736A discloses an oscillation and mixing device for medical reagents. The semi-convex sphere on the upper surface of the fixed frame slides along the outer surface of the semi-convex sphere on the lower surface of the movable plate, so that the reagents inside the reagent box can be oscillated in the vertical direction. By heating the water flow inside the heating box, the telescopic hose draws the water flow inside the heating box and transports it to the reagent box, thereby preheating the internal space of the reagent box.

[0005] However, the above-mentioned reagent kit for content determination still has the following problems during the use of reagents: although the reagent tube is oscillated by the oscillation mechanism inside the reagent kit, the oscillation range of such oscillation mechanism is small, and the reagents inside the reagent tube cannot be evenly blended. At the same time, the continuous oscillation mechanism is difficult to effectively assist the efficient fusion of the reagent liquid and the auxiliary liquid, thereby affecting the oscillation mixing effect. Summary of the invention

[0006] The object of the present invention is to provide an acetic acid content determination kit with an oscillation structure, in order to solve the problem that the oscillation of the reagent tube is achieved by the oscillation mechanism inside the kit, but the oscillation range of such oscillation mechanism is small, and the reagent inside the reagent tube cannot be evenly blended. At the same time, the continuous oscillation mechanism is difficult to effectively assist the efficient fusion of the reagent liquid and the auxiliary liquid, thereby affecting the oscillation mixing effect.

[0007] To achieve the above object, the present invention provides the following technical solution: a kit for determining acetic acid content with an oscillating structure, comprising a kit body and a protective top cover hingedly arranged at the rear of the kit body, and an oscillating cavity is opened at the inner center of the kit body; and further comprising:

[0008] A cleaning mechanism is provided on the inner side of the protective top cover, and the cleaning mechanism includes a cleaning brush rod, and the bottom end of the cleaning brush rod slides through the left and right sides of the bottom end inside the protective top cover;

[0009] Among them, an oscillation mechanism is arranged in the oscillation cavity inside the test kit body, and the oscillation mechanism includes a guide positioning plate, and the guide positioning plate is fixedly installed at the lower part of the inner part of the oscillation cavity;

[0010] The oscillation mechanism includes a positioning disc, and the positioning disc is rotatably arranged above the oscillation cavity inside the reagent box body, and the outer side of the bottom surface of the positioning disc is slidably engaged with the top of the supporting and contacting plate at an equal angle;

[0011] The bottom end of the support and contact plate arranged at an equal angle included in the oscillation mechanism is fixedly arranged on the top surface of the guide positioning plate, and an anti-slip groove is opened on the upper part of the guide positioning plate, and a bearing at the inner center position of the guide positioning plate is connected to the bottom end of the output shaft of the drive motor;

[0012] The oscillation mechanism comprises reagent placement holes, and the reagent placement holes are arranged at equal angles inside the positioning disc, and the outer middle parts of the reagent placement holes at equal angles are all provided with oscillation slide grooves, and the insides of the reagent placement holes arranged at equal angles are all provided with reagent lifting rings;

[0013] The reagent lifting ring included in the oscillation mechanism has lifting shafts fixedly disposed on both ends thereof, and the outer ends of the symmetrically disposed lifting shafts are slidably engaged in the interior of the oscillation chute, so that the reagent lifting ring can rotate and tilt in the reagent placement hole.

[0014] Preferably, the cleaning mechanism comprises a measuring contact pad, and the measuring contact pad is fixedly arranged at the inner center position of the protective top cover, and a side of the measuring contact pad away from the protective top cover is in contact with a symmetrically arranged cleaning brush rod.

[0015] Preferably, the cleaning mechanism includes a hinged shaft, and the hinged shaft is arranged at the hinge between the reagent box body and the protective top cover, and the hinged shaft and the reagent box body are fixedly connected, and reciprocating threaded grooves are provided on the left and right outer walls of the hinged shaft.

[0016] Preferably, the cleaning mechanism comprises a threaded sleeve, and the threaded sleeve is threadedly connected to the reciprocating threaded groove on the outer wall of the hinged shaft, and the outer end of the threaded sleeve is fixedly connected to the inner side of the bottom end of the left and right cleaning brush rods.

[0017] Preferably, the oscillation mechanism includes an engaging protrusion, and the engaging protrusion is fixedly arranged on the left and right sides of the bottom surface of the positioning disk, and a driving disk body is arranged in the middle of the bottom surface of the positioning disk, and the driving disk body is fixedly connected to the upper outer wall of the output shaft, and the internal elasticity of the driving disk body is elastically arranged with a resisting protrusion.

[0018] Preferably, the oscillation mechanism includes a guide arc plate, and the guide arc plate is fixedly arranged in front of the bottom surface of the guide positioning disk, and the top end of the guide arc plate extends to the bottom surface of the driving disk body, so that the interference protrusion inside the driving disk body can be driven by the guide arc plate to slide inward, thereby disengaging from the engagement with the bite protrusion.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: the acetic acid content determination kit provided with an oscillating structure allows the cleaning mechanism to clean the determination contact pad by flipping the protective top cover, thereby avoiding residue and preventing the reagent from overflowing, and at the same time, an intermittent fast and slow rotating oscillating mechanism is used to drive the reagent tube to rotate, and the oscillation is achieved by a resistance method, thereby avoiding the single oscillation mixing method from affecting the uniformity. The specific contents are as follows:

[0020] 1. The acetic acid reagent tube is placed in the reagent placement hole inside the positioning disc so that the reagent lifting ring can lift and limit the reagent tube. At the same time, the bottom end of the reagent tube is placed in the anti-slip groove opened inside the guide positioning disc to avoid displacement during subsequent oscillation operations.

[0021] 2. Flip the protective top cover forward, and the threaded sleeve connected to the reciprocating threaded groove on the outer wall of the hinged shaft is fixedly connected to the bottom end of the cleaning brush rod, so that the rotating threaded sleeve drives the cleaning brush rod to slide outward synchronously, so as to drive the cleaning mechanism to work according to the opening and closing of the protective top cover.

[0022] When the cleaning brush rod slides, it cleans the fitted measurement contact pad to prevent the residual reagent liquid from previous measurements from affecting the current measurement data. At the same time, the flexible measurement contact pad fits the top of the reagent tube, which does not affect the tilt of the reagent tube during the oscillation process and can prevent liquid leakage.

[0023] 3. The output shaft drives the driving disc body and the abutment protrusions on its outer side to rotate, and the abutment protrusions contact each other with the engaging protrusions on the bottom of the positioning disc, thereby driving the positioning disc and the internal reagent tube to rotate synchronously, thereby assisting the acetic acid inside the reagent tube to rotate and mix.

[0024] The rotating interference protrusion is limited by the guide arc plate, so that it slides into the inside of the driving disk body, and the non-interfering bite protrusion and the positioning disc stop rotating, driving the positioning disc and the reagent tube to rotate again, and intermittently assisting the acetic acid inside the reagent tube to rotate, thereby assisting the acetic acid to improve the mixing effect by alternating fast and slow.

[0025] There is intermittent friction between the reagent tube and the support and contact plate, and then the reagent tube is driven to tilt through the support and contact plate. At the same time, the reagent lifting ring for limiting the reagent tube slides inside the oscillation slide groove through the lifting shaft rod at the outer end, so as to achieve a certain angle of tilt, avoiding the single oscillation mixing method from affecting the uniformity.

Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-Figure 11 , the present invention provides the following technical solutions:

[0040] Embodiment 1: In order to solve the problems existing in the existing acetic acid content determination kit when in use, this embodiment adopts the following technical scheme: an acetic acid content determination kit with an oscillation structure, comprising a kit body 1, and a protective top cover 2 hingedly arranged at the rear of the kit body 1, and an oscillation cavity 3 is opened at the inner center position of the kit body 1; wherein, an oscillation mechanism is arranged in the oscillation cavity 3 inside the kit body 1, and the oscillation mechanism includes a guide positioning disk 5, and the guide positioning disk 5 is fixedly installed at the lower part of the inner part of the oscillation cavity 3; the oscillation mechanism includes a positioning disk 10, and the positioning disk 10 is rotatably arranged above the oscillation cavity 3 inside the kit body 1, and the outer side of the bottom surface of the positioning disk 10 is slidably engaged with the top of the supporting contact plate 11 at equal angles.

[0041] The oscillation mechanism includes reagent placement holes 12, and the reagent placement holes 12 are opened at equal angles inside the positioning disk 10, and an oscillation chute 13 is opened in the middle of the outer side of the reagent placement holes 12 at equal angles, and reagent lifting rings 14 are arranged inside the reagent placement holes 12 arranged at equal angles; the reagent lifting rings 14 included in the oscillation mechanism are fixedly provided with lifting shafts 15 at both ends, and the outer ends of the symmetrically arranged lifting shafts 15 are slidably engaged with the inside of the oscillation chute 13, so that the reagent lifting ring 14 can rotate and tilt inside the reagent placement hole 12.

[0042] like Figure 5 , Figure 7-Figure 8As shown, when the acetic acid content needs to be measured, the acetic acid reagent tube is placed in the reagent placement hole 12 opened inside the positioning disc 10, so that the reagent lifting ring 14 inside the reagent placement hole 12 can lift and limit the reagent tube, and at the same time, the bottom end of the reagent tube is placed in the anti-slip groove 20 opened inside the guide positioning disc 5, thereby avoiding displacement and misalignment during subsequent oscillation operations.

[0043] Embodiment 2: In order to solve the problems existing in the use of the existing acetic acid content determination kit, this embodiment adopts the following technical scheme: a cleaning mechanism is provided on the inner side of the protective top cover 2, and the cleaning mechanism includes a cleaning brush rod 4, and the bottom end of the cleaning brush rod 4 slides through the left and right sides of the bottom end inside the protective top cover 2; the cleaning mechanism includes a determination contact pad 6, and the determination contact pad 6 is fixedly arranged at the inner center position of the protective top cover 2, and the side of the determination contact pad 6 away from the protective top cover 2 is in contact with the symmetrically arranged cleaning brush rod 4.

[0044] The cleaning mechanism includes a hinged shaft 7, and the hinged shaft 7 is arranged at the hinge between the reagent box body 1 and the protective top cover 2, and the hinged shaft 7 is fixedly connected to the reagent box body 1, and the left and right outer walls of the hinged shaft 7 are provided with reciprocating thread grooves 8; the cleaning mechanism includes a threaded sleeve 9, and the threaded sleeve 9 is threadedly connected to the reciprocating thread groove 8 on the outer wall of the hinged shaft 7, and the outer end of the threaded sleeve 9 is fixedly connected to the inner side of the bottom end of the cleaning brush rod 4 on the left and right sides.

[0045] like Figure 3-Figure 4 As shown, the protective top cover 2 hinged at the rear of the reagent box body 1 is flipped downward, so that the protective top cover 2 rotates around the hinge shaft 7 at the bottom hinge, and then the threaded sleeve 9 connected to the reciprocating threaded groove 8 on the outer wall of the hinge shaft 7 is fixedly connected to the bottom end of the cleaning brush rod 4, so that the rotating threaded sleeve 9 drives the cleaning brush rod 4 to slide synchronously outward, so that the cleaning brush rod 4 cleans the fitted measurement contact pad 6 to avoid the residual reagent liquid from the previous measurement affecting the measurement data this time. At the same time, the flexible measurement contact pad 6 is fitted to the top of the reagent tube, which does not affect the inclination of the reagent tube during the oscillation process and can avoid liquid leakage.

[0046] Embodiment 3: In order to solve the problems existing in the use of the existing acetic acid content determination kit, the present embodiment adopts the following technical scheme: the bottom end of the support and contact plate 11 arranged at equal angles included in the oscillation mechanism is fixedly arranged on the top surface of the guide positioning disk 5, and an anti-slip groove 20 is opened on the upper part of the inner part of the guide positioning disk 5, and the bearing at the inner center position of the guide positioning disk 5 is connected to the bottom end of the output shaft 21 of the drive motor; the oscillation mechanism includes an engaging protrusion 16, and the engaging protrusion 16 is fixedly arranged on the left and right sides of the bottom surface of the positioning disk 10, and a driving disk body 17 is arranged in the middle of the bottom surface of the positioning disk 10, and the driving disk body 17 is fixedly connected to the upper outer wall of the output shaft 21, and the inner part of the driving disk body 17 is elastically provided with a contact protrusion 18.

[0047] The oscillation mechanism includes a guide arc plate 19, and the guide arc plate 19 is fixedly arranged in front of the bottom surface of the guide positioning plate 5, and the top end of the guide arc plate 19 extends to the bottom surface of the driving plate body 17, so that the interference protrusion 18 inside the driving plate body 17 can be driven by the guide arc plate 19 to slide inward, thereby disengaging from the engagement with the bite protrusion 16.

[0048] like Figure 8-Figure 11 As shown, the motor installed at the lower part of the reagent box body 1 drives the output shaft 21 and the driving disk body 17 to rotate. At the same time, when the driving disk body 17 is rotated by the abutment protrusion 18 protruding from the outside, the abutment protrusion 18 and the engaging protrusion 16 on the bottom surface of the positioning disk 10 contact each other, thereby pushing the positioning disk 10 and the internal reagent tube to rotate synchronously, thereby assisting the rotation and mixing of acetic acid in the reagent tube.

[0049] Furthermore, after the driving disc 17 drives the abutment protrusion 18 to rotate to the inner side of the guide arc plate 19, the abutment protrusion 18 is limited by the guide arc plate 19 and made to slide to the inside of the driving disc 17, while the bite protrusion 16 and the positioning disc 10 which are not interfered with stop rotating, and after the driving disc 17 rotates out, the abutment protrusion 18 engages with the bite protrusion 16 again, thereby driving the positioning disc 10 and the reagent tube to rotate again, intermittently assisting the rotation of acetic acid inside the reagent tube, thereby assisting the acetic acid to improve the oscillation mixing effect by alternating fast and slow.

At the same time, the reagent lifting ring 14 for limiting the reagent tube slides inside the oscillation slide groove 13 through the lifting shaft rod 15 at the outer end, so as to achieve a certain angle of inclination while improving the oscillation mixing effect.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
