Description

Technical Field

[0001] This application relates to the field of bioengineering technology, and in particular to a dispensing device. Background Technology

[0002] In recent years, with the rapid development of microfluidic technology, spherical bodies such as lyophilized bulbs have been widely used in many fields, including biomedical research, clinical diagnosis, drug development, food hygiene, and environmental monitoring. As biological reagents, lyophilized bulbs have a longer shelf life than liquid reagents, and are also more convenient to transport and use. However, lyophilized bulbs are relatively fragile and cannot withstand high pressure. After freeze-drying, different types of lyophilized bulbs need to be rapidly dispensed into storage containers at low temperatures for sealing and storage to prevent them from becoming damp and denatured. Dispensing equipment can effectively dispense lyophilized bulbs into storage containers; however, traditional dispensing equipment typically suffers from complex structures and low efficiency during the dispensing process. Summary of the Invention

[0003] One of the technical problems addressed by this application is how to improve the working efficiency of packaging equipment while maintaining a simple structure.

[0004] A dispensing device, comprising:

[0005] A storage mechanism having a storage cavity and a release hole, the release hole connecting the outside to the storage cavity, the storage cavity for storing spherical objects, and the release hole accommodating one spherical object at a time;

[0006] A dispensing mechanism, wherein the dispensing mechanism is disposed on the storage mechanism and has dispensing holes; and

[0007] A control valve is movably connected to the storage mechanism and has a dispensing position and a blocking position. In the blocking position, the release port is blocked by the control valve and isolated from the dispensing port. In the dispensing position, the release port is opened by the control valve and communicates with the dispensing port.

[0008] In one embodiment, a flow guide groove is formed on the bottom wall of the storage cavity, and the release hole is disposed on the bottom wall at the end of the flow guide groove.

[0009] In one embodiment, the width of the guide groove is approximately equal to the diameter of the release hole.

[0010] In one embodiment, a guide groove is further provided on the bottom wall of the storage cavity. The guide groove is connected to the end of the flow channel away from the release hole, and the width of the guide groove is greater than the width of the flow channel.

[0011] In one embodiment, the first guide segment connects the flow channel and the second guide segment, the width of the second guide segment is greater than the width of the first guide segment, and the width of the first guide segment gradually decreases from one end of the first guide segment near the second guide segment to one end near the flow channel; and / or

[0012] The dispensing equipment is capable of oscillating about an axis that is simultaneously perpendicular to both the direction of gravity and the extension direction of the guide groove.

[0013] In one embodiment, the storage cavity includes a first storage segment and a second storage segment that are interconnected, the width of the second storage segment being greater than the width of the first storage segment, the release hole being connected to the end of the first storage segment away from the second storage segment, and the width of the first storage segment gradually decreasing from the end of the first storage segment near the second storage segment to the end away from the second storage segment.

[0014] In one embodiment, the control valve has a control hole that allows the sphere to pass through. In the blocking position, the control hole is misaligned with the release hole and the dispensing hole. In the dispensing position, the control hole is aligned with the release hole and the dispensing hole.

[0015] In one embodiment, the control valve is movably disposed between the dispensing mechanism and the storage mechanism, and the control valve is capable of linear motion relative to the dispensing mechanism and the storage mechanism.

[0016] In one embodiment, the dispensing mechanism includes a support portion and a boss portion, the boss portion protruding from the support portion, the control valve having a guide hole, the control valve being supported on the support portion, and the boss portion being movably disposed in the guide hole.

[0017] In one embodiment, the dispensing hole includes a first dispensing section and a second dispensing section that are interconnected. The first dispensing section is closer to the release hole than the second dispensing section. The diameter of the first dispensing section is larger than the diameter of the second dispensing section. The diameter of the first dispensing section gradually decreases from the end of the first dispensing section away from the second dispensing section to the end of the first dispensing section closer to the second dispensing section.

[0018] One technical advantage of one embodiment of this application is that, since only one spherical object can be accommodated in the release orifice at a time, when the control valve is in the blocking position, only one spherical object enters the release orifice from the storage cavity, and this released spherical object cannot enter the dispensing orifice due to the blocking effect of the control valve. At this time, when the control valve is moved from the blocking position to the dispensing position, the control valve stops blocking the release orifice, allowing the release orifice to open and communicate with the dispensing orifice. One spherical object from the release orifice falls into the dispensing orifice, and this single spherical object continues to be output from the dispensing orifice and enters the storage container, thus completing one dispensing operation of the spherical object by the dispensing device. Therefore, the dispensing device can effectively ensure that only one spherical object is output at a time. This effectively prevents the dispensing device from outputting multiple spherical objects at once, avoiding the removal of excess spherical objects and thus improving the working efficiency of the dispensing device. On the other hand, it can prevent multiple spherical objects from getting stuck in the release hole and dispensing hole and failing to fall out, thus saving time in clearing the release hole and dispensing hole and further improving the working efficiency of the dispensing equipment. At the same time, it can also effectively prevent powder falling off due to multiple spherical objects getting stuck and rubbing in the release hole and dispensing hole, and prevent damage to the spherical objects during the dispensing process, thereby improving the reliability of the dispensing equipment.

[0034] See Figure 1 , Figure 2 and Figure 3This application provides a dispensing device 10 for dispensing spherical bodies 20, which may be freeze-dried spheres or the like. The dispensing device 10 includes a storage mechanism 100, a dispensing mechanism 200, and a control valve 300. The storage mechanism 100 has a storage cavity 110 and a release hole 120. The volume of the storage cavity 110 is much larger than the volume of the release hole 120. The storage cavity 110 and the release hole 120 are connected. The release hole 120 can be opened on the bottom wall surface of the storage cavity 110. The spherical body 20 can be accommodated in the storage cavity 110. The release hole 120 can accommodate one spherical body 20 at a time. In other words, along the axial and radial directions of the release hole 120, the release hole 120 can only accommodate one spherical body 20 at a time. The dispensing mechanism 200 is mounted on the storage mechanism 100. For example, the dispensing mechanism 200 can be fixedly connected to the storage mechanism 100. The dispensing mechanism 200 has a dispensing hole 210 through which the spherical body 20 flows out of the entire dispensing device 10, allowing the spherical body 20 flowing out of the dispensing hole 210 to be dispensed into the storage container, thus realizing the storage and transportation of the spherical body 20 by the storage container. The control valve 300 is movably connected to the storage mechanism 100. The control valve 300 can move relative to the storage mechanism 100 and the dispensing mechanism 200, so that the control valve 300 has a dispensing position and a blocking position relative to the storage mechanism 100. Therefore, the control valve 300 can reciprocate between the dispensing position and the blocking position. When in the blocking position, the release hole 120 is blocked by the control valve 300, which isolates the release hole 120 from the dispensing hole 210. When in the dispensing position, the release hole 120 is opened by the control valve 300, which connects the release hole 120 to the dispensing hole 210.

[0035] During operation, when a spherical object 20 is present in the release orifice 120, the control valve 300 can be moved to the blocking position, blocking the release orifice 120 and isolating it from the dispensing orifice 210. The spherical object 20 in the release orifice 120 cannot enter the dispensing orifice 210. At this point, the control valve 300 can be moved from the blocking position to the dispensing position, opening the release orifice 120 and connecting it to the dispensing orifice 210. Under the influence of gravity, the spherical object 20 in the release orifice 120 will enter the dispensing orifice 210 and ultimately exit from the dispensing orifice 210 into the storage container, thus realizing the dispensing of the spherical object 20 by the dispensing device 10.

[0036] In traditional dispensing equipment, spherical objects enter directly from the storage cavity to the release port, allowing them to be directly fed into the storage container. However, the diameter of the release port is usually quite large, meaning that two spherical objects can simultaneously exist within it along its radial direction. During the dispensing process, several spherical objects are first placed into the storage cavity, from which they then enter the release port. However, the spherical objects cannot enter the release port one by one sequentially, resulting in multiple spherical objects entering the release port simultaneously. This prevents the release port from outputting only one spherical object at a time; when multiple spherical objects are output at once, the excess spherical objects need to be removed, impacting efficiency. Furthermore, multiple spherical objects may become stuck in the release port, preventing output. This necessitates unblocking the release port, which significantly delays the process and further reduces the efficiency of the dispensing equipment. On the other hand, when multiple spheres pass through the release hole or get stuck, friction will occur between two adjacent spheres, causing powder to fall off the spheres. This will affect the spheres and thus the reliability of the dispensing equipment.

[0037] See Figure 1 , Figure 2 and Figure 3 Regarding the dispensing device 10 in the above embodiment, since the release hole 120 can only accommodate one spherical body 20 at a time, when the control valve 300 is in the blocking position, only one spherical body 20 in the storage cavity 110 enters the release hole 120 from the storage cavity 110, and the released spherical body 20 cannot enter the dispensing hole 210 due to the blocking of the control valve 300. At this time, when the control valve 300 is moved from the blocking position to the dispensing position, the control valve 300 will stop blocking the release hole 120, so that the release hole 120 is open and connected to the dispensing hole 210. One spherical body 20 will fall from the release hole 120 into the dispensing hole 210, and this spherical body 20 will continue to be output from the dispensing hole 210 and enter the storage container, thus completing one dispensing of the spherical body 20 by the dispensing device 10. Therefore, the dispensing device 10 can effectively ensure that only one spherical object 20 is output at a time. This effectively prevents the dispensing device 10 from outputting multiple spherical objects 20 at once, avoiding the need to remove excess spherical objects 20 and thus improving the working efficiency of the dispensing device 10. On the other hand, it prevents multiple spherical objects 20 from getting stuck in the release hole 120 and dispensing hole 210, thus saving time spent clearing these holes and further improving the working efficiency of the dispensing device 10. Simultaneously, it also effectively prevents powder shedding caused by multiple spherical objects 20 getting stuck and rubbing in the release hole 120 and dispensing hole 210, avoiding damage to the spherical objects 20 during the dispensing process, thereby improving the reliability of the dispensing device 10.

[0038] See Figure 3 , Figure 4 and Figure 5 In some embodiments, a guide groove 130 is formed on the bottom wall of the storage cavity 110, and a release hole 120 is provided on the bottom wall at the end of the guide groove 130. Therefore, by setting the guide groove 130, a limited number of spherical bodies 20 in the guide groove 130 are sequentially input from the guide groove 130 to the release hole 120 under the action of gravity. This can reduce the jamming caused by the spherical bodies 20 inputting from the storage cavity 110 to the release hole 120, and ensure that the spherical bodies 20 in the storage cavity 110 smoothly pass through the guide groove 130 to the release hole 120. This effectively avoids the phenomenon that no spherical bodies 20 are input into the release hole 210 when the control valve 300 is in the dispensing position. This ensures that there is a release hole 120 outputting from the dispensing hole 210 every time the control valve 300 is in the dispensing position, thereby improving the reliability of the dispensing equipment 10.

[0039] See Figure 3 , Figure 4 and Figure 5 In some embodiments, the guide channel 130 can extend approximately in a straight line, and the width of the guide channel 130 is approximately equal to the diameter of the release hole 120. In other words, the width of the guide channel 130 can be approximately equal to the diameter of a sphere 20. Therefore, along the width direction of the guide channel 130, the guide channel 130 can only accommodate one sphere 20 at a time. This can avoid the jamming phenomenon caused by accommodating multiple spheres 20 at the same time, prevent the spheres 20 from shedding powder due to jamming and friction, and ensure that the spheres 20 are smoothly and quickly transported from the guide channel 130 to the release hole 120, thereby improving the working efficiency of the dispensing equipment 10.

[0040] See Figure 3 , Figure 4 and Figure 5 In some embodiments, a guide groove 140 is also provided on the bottom wall of the storage cavity 110. The guide groove 140 is connected to the end of the guide groove 130 away from the release hole 120, and the width of the guide groove 140 is greater than the width of the guide groove 130. By providing the guide groove 140, the guide groove 140 can converge and guide the spherical body 20, so that the spherical body 20 in the guide groove 140 can smoothly enter the guide groove 130, thereby avoiding the spherical body 20 from getting stuck in the process of inputting into the guide groove 130, avoiding the spherical body 20 from shedding powder due to jamming and friction, and also ensuring that the spherical body 20 is smoothly and quickly transported from the guide groove 130 to the release hole 120, thereby improving the working efficiency of the dispensing equipment 10.

[0041] See Figure 3 , Figure 4 and Figure 5In some embodiments, the guide groove 140 includes a first guide section 141 and a second guide section 142. The first guide section 141 connects the guide groove 130 and the second guide section 142, that is, the first guide section 141 is located between the guide groove 130 and the second guide section 142. The width of the second guide section 142 is greater than the width of the first guide section 141. From the end of the first guide section 141 near the second guide section 142 to the end near the guide groove 130, the width of the first guide section 141 gradually decreases. Thus, the width of the second guide section 142 can remain constant from one end to the other. Therefore, the first guide section 141 is approximately conical. The sharp part of the first guide section 141 is directly connected to the guide groove 130. Thus, the first guide section 141 can fully exert its function of converging and guiding the spherical body 20, so that the spherical body 20 quickly passes through the guide groove 140 and the guide groove 130 and enters the release hole 120, thereby improving the working efficiency of the dispensing equipment 10.

[0042] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the dispensing device 10 is capable of oscillating about an axis that is simultaneously perpendicular to both the direction of gravity and the extension direction of the guide groove 140. The direction of gravity can be understood as the up-down direction, and the extension direction of the guide groove 140 can be understood as the left-right direction. Therefore, the extension direction of the axis of oscillation of the dispensing device 10 can be understood as the front-back direction, meaning the dispensing device 10 oscillates about an axis extending in the front-back direction. Clearly, both the front-back direction and the horizontal direction are horizontal. Specifically, see [reference needed]. Figure 2 When the control valve 300 is in the blocked position, the dispensing device 10 can be swung counterclockwise by a certain angle, so that the left end of the dispensing device 10 is lower than the right end in the vertical direction. That is, the position near the release end of the guide channel 130 is lower than the position away from the release hole 120. This allows the spherical body 20 in the guide channel 130 to flow more quickly into the release hole 120 under gravity, thereby improving the conveying efficiency of the spherical body 20 and ultimately improving the working efficiency of the dispensing device 10. When it is necessary to move the control valve 300 from the blocked position to the dispensing position, refer to... Figure 3The dispensing device 10 can be swung clockwise at a certain angle, so that the left end of the dispensing device is higher than the right end in the vertical direction, that is, the position near the release end in the guide channel 130 is higher than the position away from the release hole 120. At this time, due to the blocking effect of the release hole 120, the spherical body 20 that has entered the release hole 120 will not be able to exit from the release hole 120 and will re-enter the guide channel 130. The spherical body 20 in the guide channel 130 will move away from the release hole 120. Therefore, when the control valve 300 moves from the blocking position to the dispensing position, one spherical body 20 stored in the release hole 120 will fall smoothly into the dispensing hole 210 for output. Given that the release hole 120 is located at a relatively high position, the spherical body 20 in the guide channel 130 will not be able to enter the release hole 120. Therefore, during the process of the control valve 300 moving from the dispensing position to the sealing position, the spherical body 20 in the guide channel 130 will not be able to enter the release hole 120, effectively preventing the spherical body 20 from entering the dispensing hole 210 from the release hole 120, thereby providing reliability for the operation of the dispensing equipment 10.

[0043] See Figure 4 In some embodiments, the storage cavity 110 includes a first storage segment 111 and a second storage segment 112, which are interconnected. The width of the second storage segment 112 is greater than the width of the first storage segment 111. The release hole 120 is connected to the end of the first storage segment 111 away from the second storage segment 112. From the end of the first storage segment 111 near the second storage segment 112 to the end away from the second storage segment 112, the width of the first storage segment 111 gradually decreases. This also makes the first storage segment 111 approximately conical, so the first storage segment 111 can also fully exert its function of converging and guiding the spherical body 20, allowing the spherical body 20 in the storage cavity 110 to smoothly enter the release hole 120, thereby improving the working efficiency of the dispensing device 10.

[0044] See Figure 1 , Figure 6 , Figure 7 and Figure 8In some embodiments, the control valve 300 has a control hole 310 through which the spherical body 20 can pass. In the blocking position, the control hole 310 is offset vertically from both the release hole 120 and the dispensing hole 210, thus isolating the release hole 120 and the dispensing hole 210. In the dispensing position, the control hole 310 is aligned with both the release hole 120 and the dispensing hole 210, allowing the release hole 120 to communicate with the dispensing hole 210 through the control hole 310. In other embodiments, a gap exists between the storage mechanism 100 and the packaging mechanism. In the blocking position, the control valve 300 blocks the release hole 120. In the dispensing position, the control valve 300 opens the release hole 120, allowing the spherical body 20 in the release hole 120 to pass through this gap into the dispensing hole 210, thus also dispensing the spherical body 20.

[0045] See Figure 1 , Figure 6 , Figure 7 and Figure 8 In some embodiments, the control valve 300 is movably disposed between the dispensing mechanism 200 and the storage mechanism 100, and the control valve 300 can move linearly relative to the dispensing mechanism 200 and the storage mechanism 100. That is, through the reciprocating movement of the control valve 300 relative to the dispensing mechanism 200 and the storage mechanism 100, the control valve 300 moves between the sealing position and the dispensing position, and also aligns or misaligns the control orifice 310 with respect to the release orifice 120 and the dispensing orifice 210. In other embodiments, the control valve 300 is rotatably disposed between the dispensing mechanism 200 and the storage mechanism 100, so that the control valve 300 moves circumferentially relative to the dispensing mechanism 200 and the storage mechanism 100, which similarly allows the control valve 300 to move between the sealing position and the dispensing position, thereby aligning or misaligning the control orifice 310 with respect to the release orifice 120 and the dispensing orifice 210.

[0046] See Figure 1 , Figure 6 , Figure 7 and Figure 8 In some embodiments, the dispensing mechanism 200 includes a support portion 220 and a boss portion 230. The boss portion 230 protrudes from the support portion 220, and a guide hole 320 is provided on the control valve 300. The control valve 300 is supported on the support portion 220, and the boss portion 230 is movably disposed in the guide hole 320. By movably disposing the boss portion 230 in the guide hole 320, the movement of the control valve 300 is well guided, preventing the control valve 300 from jamming during movement, thereby improving the movement accuracy of the control valve 300.

[0047] It can be understood that there are multiple storage chambers 110, flow channels 130, control holes 310 and dispensing holes 210, and the four form a one-to-one correspondence. Therefore, the dispensing equipment 10 can output multiple spherical bodies 20 from multiple dispensing holes 210, thereby further improving the working efficiency of the dispensing equipment 10.

[0048] See Figure 1 , Figure 6 , Figure 7 and Figure 8 In some embodiments, the dispensing hole 210 includes a first dispensing section 211 and a second dispensing section 212, which are interconnected. The first dispensing section 211 is closer to the release hole 120 than the second dispensing section 212, i.e., the first dispensing section 211 is located above the second dispensing section 212. The diameter of the first dispensing section 211 is larger than the diameter of the second dispensing section 212. From the end of the first dispensing section 211 away from the second dispensing section 212 to the end closer to the second dispensing section 212, i.e., from the upper end to the lower end of the first dispensing section 211, the diameter of the first dispensing section 211 gradually decreases. Of course, from the upper end to the lower end of the second dispensing section 212, the diameter of the second dispensing section 212 can remain constant. Therefore, by setting the first dispensing section 211, which is roughly funnel-shaped, the ball 20 falling from the release hole 120 is made to smoothly enter the first dispensing section 211, thereby ensuring that the ball 20 in the release hole 120 is smoothly output through the dispensing hole 210, and ultimately improving the reliability of the dispensing equipment 10.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
