[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.
[0026] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.
[0027] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.
[0028] In the following specific embodiments, the stir bar dispensing device can be used at different stations in the testing system to stir the reagent at different stations. For example, the stir bar dispensing device can be applied to the color titration station to stir the reagent before color titration, thereby making the sample testing more accurate. For example, the stir bar dispensing device can also be used in the atomic absorption station, where the reagent is stirred by the stir bar before atomic absorption, and the stirred reagent is then diluted to a predetermined volume before atomic absorption testing. The structure and function of the stir bar dispensing device are described below with reference to various embodiments.
[0029] In some embodiments, such as Figure 1 As shown, the stirring dispensing device 1 includes: a first dispensing plate 10 and a second dispensing plate 20. The first dispensing plate 10 has a plurality of spaced-apart first dispensing slots 11. The second dispensing plate 20 is located below the first dispensing plate 10 and has a plurality of second dispensing slots 21. The first dispensing plate 10 and the second dispensing plate 20 can be spaced along a first direction (the first direction is as shown in the figure). Figure 1 (As indicated by the middle arrow) Relative sliding, the relative positions of the first dispensing plate 10 and the second dispensing plate 20 can be changed by the relative sliding of the first dispensing plate 10 and the second dispensing plate 20, so that the first dispensing plate 10 and the second dispensing plate 20 form a first relative position and a second relative position. When the first dispensing plate 10 and the second dispensing plate 20 form a first relative position, the first dispensing slot 11 and the second dispensing slot 21 are connected. When the first dispensing plate 10 and the second dispensing plate 20 form a second relative position, the first dispensing slot 11 and the second dispensing slot 21 are staggered, so that the second dispensing plate 20 blocks the first dispensing slot 11. By positioning the first dispensing plate 10 and the second dispensing plate 20 in different relative positions, batch dispensing of stirrers can be achieved. Specifically, the stirrer dispensing device is positioned above a container holding a reagent to be stirred, with each first dispensing slot 11 or second dispensing slot 21 located directly above the container. By sliding the first dispensing plate 10 and the second dispensing plate 20 relative to each other to form a second relative position, the second dispensing plate 20 blocks each first dispensing slot 11. At this time, stirrers can be placed in each first dispensing slot 11, and each stirrer can be supported on the second dispensing plate 20. After the stirrers are placed, the first dispensing plate 10 and the second dispensing plate 20 are slid relative to each other to form a first relative position. At this time, the first dispensing slot 11 and the second dispensing slot 21 are connected, so that each stirrer contained in each first dispensing slot 11 falls into each container. That is, batch dispensing of multiple stirrers is achieved.
[0030] The ability of the second dispensing plate 20 to slide relative to the first dispensing plate 10 in the first direction can be achieved in different ways. For example, the first dispensing plate 10 is fixed and the second dispensing plate 20 can slide relative to the first dispensing plate 10 in the first direction. For example, the second dispensing plate 20 is fixed and the first dispensing plate 10 can slide relative to the first dispensing plate 10 in the first direction. For example, the first dispensing plate 10 and the second dispensing plate 20 can slide in the first direction respectively.
[0031] This utility model provides a stir bar dispensing device, which includes a first dispensing plate having multiple spaced-apart first dispensing slots and a second dispensing plate having multiple spaced-apart second dispensing slots. The second dispensing plate is located below the first dispensing plate, and the first and second dispensing plates can slide relative to each other in a first direction to form a first relative position and a second relative position. When the first relative position is formed, the first and second dispensing slots are connected. When the second relative position is formed, the first dispensing slots are blocked by the second dispensing plate. When a stir bar needs to be dispensed, the stir bar dispensing device is placed in a container holding the reagent to be stirred. Above the container, with each first or second dispensing slot directly above the container, the first and second dispensing plates slide relative to each other to form a second relative position, so that the second dispensing plate blocks each of the first dispensing slots. At this time, the stir bar can be placed in each of the first dispensing slots, and each stir bar can be supported on the second dispensing plate. After the stir bar is placed, the first and second dispensing plates slide relative to each other to form a first relative position. At this time, the first and second dispensing slots are connected, so that each stir bar contained in each of the first dispensing slots falls into each container. That is, the batch dispensing of multiple stir bars is realized.
[0032] In some embodiments, such as Figure 2 As shown, the stirring dispensing device 1 also includes a frame 30, wherein the first dispensing plate 10 is fixedly connected to the frame 30, and the second dispensing plate 20 is slidably connected to the frame 30. The second dispensing plate 20 can be dispensed in a first direction (the first direction is as shown in the figure). Figure 2 The first dispensing plate 10 and the second dispensing plate 20 (as indicated by the middle arrow) slide between a first position and a second position. At the first position, the first dispensing plate 10 and the second dispensing plate 20 form a first relative positional relationship, and the first dispensing slot 11 and the second dispensing slot 21 are connected. At the second position, the first dispensing plate 10 and the second dispensing plate 20 form a second relative positional relationship, and the first dispensing slot 11 is blocked by the second dispensing plate 20. That is, the first dispensing plate 10 is a fixed structure, and the second dispensing plate 20 can slide relative to the first dispensing plate 10 in a first direction. By making the lower second dispensing plate 20 a sliding structure, the first dispensing plate 10 can protect the second dispensing plate 20, thereby reducing the risk of the second dispensing plate 20 sliding due to accidental contact during the placement of the stir bar in each of the first dispensing slots 11, and thus enabling the second dispensing plate 20 to provide more reliable support for each stir bar.
[0033] In some embodiments, such as Figure 2As shown, at the second position, along the first direction, the second dispensing plate 20 protrudes from the first dispensing plate 10. The user can move the second dispensing plate 20 to the first position by pushing the part of the second dispensing plate 20 that protrudes from the first dispensing plate 10, which makes it convenient for the user to operate the second dispensing plate 20.
[0034] In some embodiments, combined with Figure 2 and Figure 3 The frame 30 has a guide portion 31, which, together with the first dispensing plate 10, forms a guide groove 311. At least a portion of the second dispensing plate 20 is located within the guide groove 311. This can be understood as follows: by fixing the upper first dispensing plate 10 to the frame 30, the first dispensing plate 10 and the guide portion 31 jointly limit and guide the second dispensing plate 20, thereby making the structure of the frame 30 more compact. Simultaneously, the guide groove 311 has an opening 312, which faces a first direction (such as...). Figure 2 (As shown by the middle arrow), thereby allowing a portion of the second dispensing plate 20 to extend out of the guide groove 311, thus enabling the second dispensing plate 20 to slide over a greater range without increasing the size of the guide groove 311 in the first direction.
[0035] In some embodiments, such as Figure 4 As shown, the stirring dispensing device also includes a reset structure 40, which is connected to the second dispensing plate 20. The reset structure 40 applies an elastic force to the second dispensing plate 20, which resets the second dispensing plate 20 to a second position. This can be understood as follows: during the movement of the second dispensing plate 20 towards the first position under the action of an external force, the reset structure 40 undergoes elastic deformation and applies an elastic force to the second dispensing plate 20. This elastic force points towards the second position. After the external force is removed, this elastic force can reset the second dispensing plate 20 to the second position. That is, when the user pushes the second dispensing plate 20 to the first position... After the stir bar is positioned and the stir bar is placed into each container, the user can remove the pushing force on the second dispensing plate 20. The second dispensing plate 20 automatically returns to its second position under the action of elastic force, returning to the position that covers the first dispensing slot 11. This facilitates the placement of the next batch of stir bar stir bar stirs. Furthermore, during the placement of the stir bar stirs into each of the first dispensing slots 11, the reset structure 40 can also overcome disturbances to the second dispensing plate 20 caused by vibrations or other factors, keeping the second dispensing plate 20 in its second position to reliably support the stir bar stirs in the first dispensing slots 11. Optionally, such as... Figure 4 As shown, the reset structure 40 connects the frame 30 and the second delivery plate 20.
[0036] In some embodiments, such as Figure 5As shown, the stir bar dispensing device 1 also includes a push plate 50, which is located above the first dispensing plate and can slide relative to the first dispensing plate 10 in the second direction. During the sliding process, the push plate 50 can contact the stir bars stacked on the first dispensing plate 10. It can be understood that multiple stir bars are placed directly on the first dispensing plate 10, and the movement of the push plate 50 can make the stir bars move on the upper surface of the first dispensing plate 10, so that each stir bar can fall into each first dispensing slot 11, saving the time of placing each stir bar into each first dispensing slot 11 separately, and further improving the efficiency of batch dispensing of stir bars. It should be noted that although the stir bars are magnetic and may be attracted by magnetic force, after a stir bar falls into the first dispensing slot 11, the side wall of the first dispensing slot 11 can block the stir bar. Under the blocking effect, the stir bar that falls into the first dispensing slot 11 can be separated from other stir bars and will not be sucked out of the first dispensing slot 11 by the magnetic force of other stir bars. Optionally, the size of the first dispensing tank 11 is slightly larger than that of the stir bar, so that each first dispensing tank 11 can hold one and only one stir bar.
[0037] Optionally, the second direction is parallel to the first direction, and the first delivery plate 10 is parallel to... Figure 2 The frame 30 is fixedly connected, and the second dispensing plate 20 slides relative to the first dispensing plate 10, reducing the risk of the first dispensing plate 10 sliding under the disturbance of the push plate 50, so that the second dispensing plate 20 can reliably support the stirrer in the first dispensing tank 11; optionally, the second direction is not parallel to the first direction, reducing the risk of the first dispensing plate 10 sliding under the disturbance of the push plate 50, so that the second dispensing plate 20 can reliably support the stirrer in the first dispensing tank 11.
[0038] In some embodiments, such as Figure 6 As shown, in the second direction (the second direction is as follows) Figure 6 As shown by the middle arrow, the inner wall of the first feeding trough 11 is a guide slope 111. In the depth direction of the first feeding trough 11, the distance between the guide slope 111 and the depth axis of the first feeding trough 111 decreases. The depth axis is an axis that passes through the geometric center point of the first feeding trough 11 and is parallel to the depth direction of the first feeding trough 11. By setting the guide slope 111, the depth of the first feeding trough 11 can be made to change from shallow to deep in the direction in which the stir bar is pushed by the push plate 50, so that the stir bar can fall into the first feeding trough 11 more easily.
[0039] In some embodiments, such as Figure 6As shown, in the second direction, the inner wall of the second side of the first dispensing tank 11 is a blocking surface 112. The second side is opposite to the first side. In the depth direction of the first dispensing tank 11, the distance between the blocking surface and the depth axis increases. It can be understood that the blocking surface 112 forms a downward inclined surface. During the process of the stirring bar falling into the first dispensing tank 11 and coming into contact with the blocking surface 112, the blocking surface 112 can apply a downward inclined force to the stirring bar. This force can more effectively overcome the magnetic attraction force applied to the stirring bar by other stirring bars, thereby more reliably separating the stirring bar from other stirring bars and keeping the stirring bar in the first dispensing tank 11.
[0040] In some embodiments, such as Figure 7 As shown, the stirring dispensing device 1 further includes a feeding device 61, which is located above the first dispensing plate 10 and in a second direction (the second direction is as shown in the figure). Figure 7 On the third side (indicated by the middle arrow), the feeding device 61 is used to output stirring particles so that multiple stirring particles are stacked above the first dispensing plate 10. This can be understood as the feeding device 61 outputting multiple stirring particles that fall above the first dispensing plate 10 and are stacked on the third side of the first dispensing plate 10. After stacking, the pusher plate 50 moves in the second direction to push the stacked stirring particles, causing them to fall into each of the first dispensing slots 11. In other words, by setting up the feeding device 61, the time spent manually stacking the stirring particles above the first dispensing plate 10 is saved, further improving the dispensing efficiency of the stirring particles. Optionally, the feeding device 61 can move vertically. After stacking the stirring particles above the first dispensing plate 10, the feeding device 61 lowers to prevent movement interference between the feeding device and the pusher plate 50.
[0041] In some embodiments, such as Figure 7As shown, the stir bar dispensing device 1 also includes a collection structure 62, which is located below the fourth side of the first dispensing plate 10. In the second direction, the fourth side is opposite to the third side. It should be noted that in order to ensure that each first dispensing slot 11 can accommodate stir bars, the number of stir bars piled on top of the first dispensing plate 10 needs to be proportional to the number of first dispensing slots 11. Moreover, there may be cases where stir bars pushed by the push plate 50 do not pass through the first dispensing slots 11 and thus do not fall into them. After the push plate 50 pushes the stir bars from the third side to the fourth side, the stir bars that do not fall into the first dispensing slots 11 will fall from the first dispensing plate 10 from the fourth side. The collection structure 62 collects the fallen stir bars, preventing them from scattering. The collected stir bars can also be used for the next dispensing of stir bars. Optionally, the collection structure 62 is connected to the feeding device 61 through a transmission channel. The stir bars collected by the collection structure 62 can be transmitted to the feeding device 61 through this transmission channel so that the stir bars can be piled up again on top of the first dispensing plate 10.
[0042] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
