DETAILED DESCRIPTION

[0033] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skilled person in the art without creating the creative labor belong to the scope of the utility model protection.

[0034] The core of the utility model discloses a reaction cup waste device, can utilize the cup component of going in the driving stuck reaction cup movement, and utilize the reaction cup extrusion of opposite rotation's cup roll and fall, avoided the stuck problem of reaction cup.

[0035] In addition, the utility model provides a biochemical analyzer including the reaction cup waste device.

[0036] The utility model discloses a reaction cup waste device, including:

[0037] The cup disc 10 is internally provided with a cup disc groove 11, and the end of the cup disc groove 11 is provided with a cup disc position 12;

[0038] The cup disc assembly 30 arranged at the cup disc position 12 includes at least two oppositely rotating cup disc rollers 31, the horizontal spacing of the two cup disc rollers 31 gradually decreases from one end close to the cup disc position 12 to one end away from the cup disc position 12, and the horizontal spacing of the two cup disc rollers 31 at the one end close to the cup disc position 12 is greater than the outer diameter of the reaction cup 40, and the horizontal spacing of the two cup disc rollers 31 at the one end away from the cup disc position 12 is less than the outer diameter of the reaction cup 40;

[0039] The cup component 20 is used to drive the reaction cup 40 to move along the cup disc groove 11 to the cup disc position 12, and drive the reaction cup 40 not falling to move to the direction where the horizontal spacing of the cup disc roller 31 decreases.

[0040] It needs to be explained that the horizontal spacing of the two cup disc rollers 31 at the one end close to the cup disc position 12 is slightly greater than the outer diameter of the reaction cup 40, rather than much greater than the outer diameter of the reaction cup 40; similarly, the horizontal spacing of the two cup disc rollers 31 at the one end away from the cup disc position 12 is slightly less than the outer diameter of the reaction cup 40, rather than much less than the outer diameter of the reaction cup 40.

[0041] Among them, the cup disc 10 is internally provided with at least one cup disc groove 11, and the cup disc groove 11 is used to transmit the reaction cup to the cup disc position 12, and the cup disc position 12 is provided below with the cup disc assembly 30, so as to make the reaction cup 40 completing detection fall and be discarded by using the cup disc assembly 30.

[0042] The cup component 20 is used to hold the reaction cup 40 to be discarded, drive the reaction cup 40 to move along the cup disc groove 11 to the cup disc position 12, and drive the reaction cup 40 not falling to move to the direction where the horizontal spacing of the cup disc roller 31 decreases; the structure of the cup component 20 and the movement mode of the reaction cup 40 need to be determined according to the shape and structure of the cup disc groove 11.

[0043] For example, when the cup disc groove 11 is a straight groove, the cup component 20 can be a linear motor or other linear power mechanism, so as to drive the reaction cup 40 to move along the cup disc groove 11;

[0044] When the cup discarding groove 11 is an arc groove or a spiral groove, the cup feeding assembly 20 can be a rotary power mechanism such as a rotary motor, so as to drive the reaction cup 40 to rotate and move along the arc or spiral cup discarding groove 11.

[0045] The cup discarding assembly 30 is used to discard the reaction cup 40 at the cup discarding position 12. In order to avoid the reaction cup 40 from being stuck, at least one cup discarding roller 31 is arranged on the left side and the right side of the cup discarding position 12. The cup discarding rollers 31 on the two sides rotate towards each other. The cup discarding rollers 31 are used to contact the reaction cup 40 and apply a downward extrusion force to the reaction cup 40 through the rotation towards each other, so that the reaction cup 40 is extruded and falls off at the end with smaller horizontal interval, thereby avoiding the reaction cup 40 from being stuck at the cup discarding position 12.

[0046] In order to make the reaction cup 40 smoothly enter between the cup discarding rollers 31 from the end of the cup discarding groove 11, the axis of the cup discarding roller 31 is usually tangent to the end of the cup discarding groove 11, so that the reaction cup channel between the two cup discarding rollers 31 is tangent to the end of the cup discarding groove 11. The distance from the cup discarding roller 31 to the end of the cup discarding groove 11 should not be too large, as shown in FIG. 6. Figure 6

[0047] Considering that the reaction cup 40 that is stuck is relatively small in number, in order to ensure the discarding efficiency, the horizontal interval of the two cup discarding rollers 31 at the end close to the cup discarding position 12 still needs to be greater than the outer diameter of the reaction cup 40. Therefore, most of the reaction cups 40 can still rely on the self-weight to fall off and be discarded. Only a small number of stuck reaction cups 40 need to be driven forward by the cup discarding rollers 31 and extruded to fall off.

[0048] In the embodiment, the cup feeding assembly 2 can drive the stuck reaction cup 40 to move in the direction in which the horizontal interval of the cup discarding rollers 31 decreases, and the cup discarding rollers 31 extrude the reaction cup 40 at the position with smaller horizontal interval to make the reaction cup 40 fall off and be discarded. The problem of blockage at the cup discarding position 12 due to the stuck reaction cup 40 is avoided, and the discarding efficiency is ensured.

[0049] Meanwhile, the horizontal interval of the cup discarding rollers 31 at the end close to the cup discarding position 12 is greater than the outer diameter of the reaction cup 40, so that most of the reaction cups 40 can directly fall off and be discarded. Compared with the case that all the reaction cups 40 are discarded by the cup discarding rollers 31, the discarding time is significantly saved, and the discarding efficiency is improved.

[0050] In addition, a collection box for collecting and containing the discarded reaction cups 40 is preferably arranged below the cup discarding assembly 30, so as to avoid the reaction cups 40 from falling everywhere. The batch processing of the discarded reaction cups 40 is facilitated, and the ground is prevented from being polluted by the residual liquid in the reaction cups 40.

[0051] On the basis of the above embodiment, the axis of the cup discarding roller 31 can be arranged parallel to the bottom surface of the cup discarding disc 10, and the axes of the two cup discarding rollers 31 are parallel.​

[0052] The two discarding rollers 31 on both sides of the discarding cup position 12 are arranged in parallel at the same height, which is conducive to controlling and adjusting the horizontal distance of the discarding rollers 31, and can avoid the situation that one of the two discarding rollers 31 is higher than the other, and only one of the two discarding rollers 31 applies extrusion force to the stuck reaction cup 40.

[0053] The discarding roller 31 can be a conical roller or other curved roller with gradually reduced diameter. In order to facilitate the processing of the discarding roller 31, the discarding roller 31 is preferably a conical roller, and the two discarding rollers 31 have the same angle of taper, so that the pressure of the two discarding rollers 31 on the reaction cup 40 is approximately the same, avoiding excessive force on one side of the reaction cup 40.

[0054] On the basis of the above embodiment, in order to realize the rotation of the discarding roller 31, the discarding roller 31 can be arranged one-to-one with the power mechanism, and the corresponding discarding roller 31 is driven by the power mechanism; or a transmission mechanism can be provided between the discarding rollers 31, and all the discarding rollers 31 are driven by a set of power mechanisms.

[0056] Therefore, when the power mechanism rotates, the power mechanism drives the discarding roller 31 directly connected thereto to rotate, and the gear pair between the discarding rollers 31 is used to drive the other discarding rollers 31 to rotate synchronously.

[0057] In order to drive the discarding roller 31 to rotate, the power mechanism is usually a discarding rotation motor 34; the connection mode of the discarding rotation motor 34 and the discarding roller 31 can be that the discarding rotation motor 34 is connected with the discarding roller 31 by a key, or the discarding rotation motor 34 is connected with the discarding roller 31 through a shaft coupling, or the discarding rotation motor 34 is connected with the discarding roller 31 through a speed reducer or a transmission mechanism.

[0058] For example, please refer to Figure 3 The power mechanism includes a discarding rotation motor 34 and a synchronous belt assembly, the driving pulley of the synchronous belt assembly is sleeved on the output shaft of the discarding rotation motor 34, the driven pulley of the synchronous belt assembly is sleeved on the discarding roller 31, and the synchronous belt 33 is sleeved outside the driving pulley and the driven pulley.

[0059] Therefore, when the discarding-rotating motor 34 rotates, the driving pulley rotates, the driving pulley drives the driven pulley to rotate through the synchronous belt 33, and the driven pulley drives the discarding-roller 31 connected thereto to rotate, and finally the discarding-roller 31 drives other discarding-rollers 31 to rotate synchronously through the meshing connection of the gear parts.

[0060] In order to ensure the installation stability of the discarding assembly 30, preferably, the discarding-rotating motor 34 and the discarding-roller 31 are respectively installed on the two sides of the discarding-roller mounting seat 32, the discarding-roller mounting seat 32 is connected with the bottom surface of the discarding disc 10, and the two are detachably connected through common fasteners such as fastening bolts and connecting pins.

[0061] On the basis of the above embodiment, the structure of the discarding disc 10 and the discarding groove 11 is limited, the discarding disc 10 is a disc, and the discarding groove 11 is a spiral groove arranged around the center of the discarding disc 10, the bottom surface of the spiral groove gradually decreases along the discarding motion direction at one end close to the discarding position 12, so that the reaction cup 40 can smoothly enter between the discarding position 12 and the discarding-roller 31.

[0062] When the discarding groove 11 is arranged as a spiral groove, in order to drive the reaction cup 40 to move along the discarding groove 11, preferably, the discarding assembly 30 comprises a discarding-rotating motor 34 and a discarding disc 10 internally provided with a discarding groove 11, the discarding-rotating motor 34 is coaxially installed on the discarding disc 10, and the discarding disc 10 is sleeved on the output shaft of the discarding-rotating motor 34, so that the discarding-rotating motor 34 drives the discarding disc 10 to relatively rotate with respect to the discarding disc 10.

[0063] The discarding disc 10 is provided with at least one discarding groove 11, and the discarding groove 11 has a certain radial component, so that the reaction cup 40 can be moved from the starting point closest to the center of the discarding disc 10 to the discarding position 12 farthest from the center of the discarding disc 10; in order to facilitate the processing of the discarding disc 10, preferably, the discarding groove 11 is arranged along the radial direction of the discarding disc 10.

[0064] The number of discarding grooves 11 is determined according to the actual discarding requirement, so as to improve the flux of the discarding device and the discarding efficiency; when the number of discarding grooves 11 is greater than or equal to two, the discarding disc 10 can be uniformly provided with a plurality of discarding grooves 11 in the circumferential direction, or the discarding grooves 11 can be distributed in the circumferential direction of the discarding disc 10 according to the spiral equidistance principle, and at this time, the discarding time required by the reaction cup 40 entering each discarding groove 11 is distributed in equal difference.
