Abstract

[0002] In modern scientific research in medicine, bioengineering, and other related disciplines, glassware is a crucial and indispensable tool, encompassing a wide variety of types. To ensure the accuracy and reliability of experiments and prevent cross-contamination between different experiments, researchers rigorously disinfect and clean used glassware after each experiment. Subsequently, to accelerate the drying process, decanting devices are typically used to assist in air-drying the glassware.
[0003] Most commercially available draining devices use a water dropper to suspend glassware and allow it to drain naturally. However, due to the diameter limitation of the water dropper, this type of draining device cannot simultaneously meet the needs of suspending and draining large-diameter glassware such as ordinary test tubes, flasks, and beakers, as well as small-diameter micro-reaction tubes, micro-centrifuge tubes, micro-condensers, and micro-volume flasks. This limitation not only reduces experimental efficiency but may also affect subsequent experiments due to untimely drying of the glassware, causing considerable inconvenience to scientific research. Utility Model Content
[0004] Therefore, it is necessary to provide a device for draining experimental vessels to address the problem that the requirements for hanging and draining large-diameter glassware and small-diameter miniature glassware cannot be met simultaneously, thus affecting experimental efficiency.

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0028] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0031] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0032] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0033] Currently, most glassware is suspended by a dripping device with a water dropper to allow it to drain naturally for the next experiment. While this design satisfies the drainage needs of some glassware to a certain extent, its applicability is significantly limited due to the relatively fixed diameter of the water dropper.
[0034] Specifically, current draining devices are ill-suited to simultaneously accommodate the hanging and draining needs of both large-diameter glassware such as ordinary test tubes, flasks, and beakers, and smaller-diameter micro-reaction tubes, micro-centrifuge tubes, micro-condensers, and micro-volume flasks, resulting in significant limitations in their use. These limitations not only reduce experimental efficiency but may also hinder subsequent experiments due to untimely drying of the glassware, causing considerable inconvenience to scientific research.
[0035] See Figure 1 and Figure 2This application provides an experimental glassware draining device, including a draining platform 1 and a ventilation mechanism 2. The draining platform 1 has a vertical plate 11, on which multiple draining components 3 are inclinedly arranged, allowing glassware to be suspended on the draining components 3 for draining. The ventilation mechanism 2 is connected to the draining components 3 to accelerate the draining speed of the glassware on the draining components 3.
[0036] For specific settings, please refer to Figure 3 The draining assembly 3 includes a draining rod 31 and a draining sleeve 32, with the draining sleeve 32 fitted over the outside of the draining rod 31. When it is necessary to hang and drain glassware with a larger diameter, the glassware with a larger diameter can be directly fitted onto the draining sleeve 32. When it is necessary to hang and drain miniature glassware with a smaller diameter, the draining sleeve 32 can be removed, and the glassware with a smaller diameter can be fitted onto the draining rod 31, thus simultaneously satisfying the requirements for hanging and draining both glassware with a larger diameter and miniature glassware with a smaller diameter.
[0037] See Figure 2 and Figure 3 The draining rod 31 has a hollow internal structure, and both the draining rod 31 and the draining kit 32 are provided with several ventilation holes 33. The ventilation mechanism 2 is set on the draining platform 1 and communicates with the draining rod 31. The ventilation mechanism 2 can introduce air into the draining rod 31 to accelerate the air circulation speed around the draining rod 31 and the draining kit 32, thereby speeding up the drying speed of the glassware.
[0038] In addition, the draining platform 1 can be a washbasin. By directly installing the draining component 3 on the upright plate 11 of the draining platform 1, glassware can be directly hung on the draining component 3 to drain after being washed at the washbasin.
[0039] Understandably, traditional draining methods typically require transferring washed glassware to a separate drain rack. This process not only increases the complexity of the operation but may also lead to contamination or damage to the glassware during transfer. This application addresses this by directly installing the drain assembly 3 onto the upright plate 11 of the sink, allowing users to hang the washed glassware directly on the drain assembly 3 to drain while washing it at the sink. This design not only reduces the movement of glassware between different areas but also avoids the potential risks associated with frequent transfers. The drain assembly 3's installation position adjacent to the sink makes the entire operation process smoother, allowing users to complete the entire washing and draining process without leaving the sink area.
[0040] In summary, the experimental glassware draining device of this application, by setting the draining component 3, allows glassware with larger diameters to be hung and drained by fitting it onto the draining kit 32, and allows miniature glassware with smaller diameters to be hung and drained by fitting it onto the draining rod 31 after removing the draining kit 32. Thus, it simultaneously meets the requirements for hanging and draining both glassware with larger diameters and miniature glassware with smaller diameters, reduces usage limitations, and ensures experimental efficiency.
[0041] See Figure 1 and Figure 2 In one embodiment, the upright plate 11 is disposed on the mounting surface of the draining platform 1, and a plurality of draining components 3 are arrayed on the side of the upright plate 11 perpendicular to the mounting surface, thereby making effective use of space. That is, in the embodiment of the application, the draining platform 1 has a mounting surface parallel to the ground reference plane, the upright plate 11 has a side perpendicular to the mounting surface, and a plurality of draining components 3 are arrayed on this side to save tabletop space on the mounting surface and to make effective use of the vertical space on the upper side of the draining platform 1. At the same time, the above structure allows the water in the glassware to flow naturally downwards along the side of the upright plate 11, not only achieving water collection, but this vertical water flow direction also helps to accelerate the draining speed, thereby ensuring draining efficiency.
[0042] In one embodiment, the tilt angle between the drain assembly 3 and the upright plate 11 is greater than or equal to 30° and less than or equal to 60°. Compared to vertical or horizontal placement, this tilt angle allows water to flow more smoothly along the surface of the drain assembly 3 by utilizing gravity, thereby reducing residual water on the surface of the drain assembly 3 and effectively shortening the draining time.
[0043] Furthermore, a tilt angle of 30° to 60° provides sufficient friction to prevent glassware from slipping during the draining process. Understandably, if the tilt angle between the drain assembly 3 and the upright plate 11 is less than 30°, the glassware may slide due to gravity; if the tilt angle between the drain assembly 3 and the upright plate 11 is greater than 60°, the glassware may tip over due to instability.
[0044] The tilt angle of 30° to 60° also makes it more convenient for users to place and retrieve the drain assembly 3. The angle is too large, so the drain assembly 3 will not need to be placed with effort when it is placed, and the angle is too small, so the drain assembly 3 will not get stuck when retrieving items.
[0045] See Figure 3 In one embodiment, the inner diameter of the drain kit 32 is greater than or equal to the outer diameter of the drain rod 31, so that there is a gap between the drain kit 32 and the drain rod 31, thereby ensuring that air can flow between the drain kit 32 and the drain rod 31, thereby ensuring the draining efficiency of the glassware fitted on the drain kit 32.
[0046] Specifically, in the embodiments of this application, the end diameter of the drain kit 32 is 0.7 cm, and the end diameter of the drain rod 31 is 0.5 cm. This size not only enables the drain kit 32 to effectively and stably suspend most glassware currently used in experiments, but also allows for air circulation between the drain kit 32 and the drain rod 31 after the drain kit 32 is fitted on the outside of the drain rod 31, thus ensuring the draining speed of the glassware.
[0047] In one embodiment, the draining rod 31 is a tapered rod, and the diameter of the end of the draining rod 31 away from the upright plate 11 is smaller than the diameter of the end of the draining rod 31 near the upright plate 11. By making the end of the draining rod 31 near the upright plate 11 have a larger diameter, the connection between the draining rod 31 and the upright plate 11 is ensured to be stable. By making the end of the draining rod 31 away from the upright plate 11 have a smaller diameter, it is convenient for glassware to be mounted on the draining rod 31 for hanging.
[0048] The drain kit 32 is a conical kit, and the diameter of the end of the drain kit 32 away from the upright plate 11 is smaller than the diameter of the end of the drain kit 32 near the upright plate 11. By making the end of the drain kit 32 near the upright plate 11 have a larger diameter, the connection between the drain kit 32 and the upright plate 11 is ensured to be stable. By making the end of the drain kit 32 away from the upright plate 11 have a smaller diameter, it is convenient for glassware to be hung on the drain kit 32.
[0049] In one embodiment, the drain assembly 3 is detachably connected to the upright plate 11 so that the drain assembly 3 can be replaced as needed. Specifically, the drain rod 31 is detachably connected to the upright plate 11, and the drain kit 32 is detachably connected to the upright plate 11. More specifically, the drain rod 31 is detachably connected to the upright plate 11 by means of a clip or screw, and the drain kit 32 is detachably connected to the upright plate 11 by means of a clip or screw.
[0050] In one embodiment, the drain assembly 3 further includes a base 34, which is disposed on the upright plate 11, and the drain kit 32 is detachably connected to the base 34. This structure allows the drain kit 32 to be independent during installation and use, and also ensures that there is a certain gap between the drain kit 32 and the drain rod 31 while the drain kit 32 is fitted onto the outside of the drain rod 31.
[0051] Specifically, the base 34 is provided with a first fixing ring 35, and one end of the drain kit 32 is inserted into the first fixing ring 35 to achieve a detachable connection between the first fixing rings 35. The drain kit 32 can be screwed to the first fixing ring 35 or snapped to the first fixing ring 35.
[0052] In one embodiment, the drain stick 31 is detachably connected to the base 34 for replacement as needed. It is understood that the drain stick 31 is prone to accumulating dirt, water stains, and bacteria during use, especially within its ventilation holes 33. With the detachable design, the user can easily remove the drain stick 31 from the base 34 and thoroughly clean it using a brush, detergent, or by rinsing it directly under running water. Furthermore, the detachable design also allows for individual replacement of the drain stick 31 when damaged, effectively reducing maintenance costs.
[0053] Specifically, the base 34 is provided with a second fixing ring 36, and one end of the draining rod 31 is inserted into the second fixing ring 36 to achieve a detachable connection with the second fixing ring 36. The draining rod 31 can be screwed to the second fixing ring 36 or snapped to the second fixing ring 36.
[0054] See Figure 1 and Figure 2 In one embodiment, the ventilation mechanism 2 includes a fan 21 and a ventilation duct 22. The upright plate 11 has an internal hollow structure. The ventilation duct 22 is installed on the fan 21 and communicates with the upright plate 11. The draining rod 31 is connected to the ventilation duct 22 through the upright plate 11, so that the fan 21 can input air into the upright plate 11 through the ventilation duct 22 and allow the air to enter the draining rod 31 to accelerate the draining speed of the glassware on the draining rod 31.
[0055] This structure utilizes the hollow interior of the upright plate 11, allowing ventilation to be achieved for multiple drain rods 31 via a single ventilation pipe 22. Compared to laying a separate ventilation pipe 22 for each drain rod 31, this not only reduces the amount of pipe material used but also significantly reduces installation workload. Furthermore, equipping each drain rod 31 with a separate ventilation pipe 22 would occupy more space, leading to a crowded equipment layout. Therefore, this structure allows for more efficient layout within a limited space.
[0056] See Figure 1 and Figure 4 In another embodiment, the ventilation mechanism 2 includes a fan 21 and a plurality of ventilation pipes 22, all of which are mounted on the upright plate 11 and connected to the fan 21 and the drain rods 31 of the plurality of draining components 3. The fan 21 can input air into the plurality of drain rods 31 through the plurality of ventilation pipes 22 to accelerate the air circulation speed around the drain rods 31, thereby accelerating the drying speed of the glassware on the drain rods 31.
[0057] This structure allows for independent control of ventilation in each drain rod 31, enabling individual adjustments based on the specific needs of each drain rod 31. This provides greater flexibility, and if a problem occurs in the ventilation duct 22 of one drain rod 31, it will not affect the ventilation effect of other drain rods 31, resulting in higher system reliability. Furthermore, this structure ensures that each drain rod 31 receives stable ventilation pressure, avoiding uneven ventilation caused by branching ducts.
[0058] In the two embodiments described above, the blower 21 can be a hot air blower 21, which introduces hot air into the glassware to further improve the draining rate. Additionally, see [link to relevant documentation]. Figure 5 To further save space, in the two embodiments described above, the fan 21 can be installed inside the draining platform 1.
[0059] 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.
[0060] 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.
