[0043] Embodiment
[0044] Before large-scale production of a new type of material, multiple tests need to be carried out in the laboratory. Generally, a round-bottom flask or a reaction kettle is used for the experiment. Since many resin polymer materials exist in the form of high-viscosity fluids, the viscous liquid will remain on the wall of the reaction vessel after the reaction and is difficult to clean. The traditional cleaning tool is generally a long brush. However, when using a long brush, the cleaning range is limited, and the cleaning efficiency is low. It has poor adaptability for cleaning round utensils such as round-bottom flasks, which greatly affects the cleaning efficiency and quality. To solve the above technical problems, the following technical solutions are provided in this embodiment:
[0045] Specifically, please refer to Figures 1-4 , this embodiment provides a cleaning device for resin experimental utensils, including a main housing 10, an inner adjustment component, an outer adjustment component, and a brush component 40;
[0046] Specifically, the main housing 10 is in a long strip shape and extends along the first direction. Its first end is closed, and the second end is provided with a first through hole (not shown in the figure). On the wall of the main housing 10 near the first end, a first fixing column 12 is provided;
[0047] Specifically, the inner adjustment component includes an inner adjustment member 22 and an inner sliding member 21 connected to the inner adjustment member 22. The inner sliding member 21 is slidably arranged in the hollow interior of the main housing 10 along the first direction. The inner adjustment member 22 is adapted to adjust the position of the inner sliding member 21 in the first direction. A second fixing column 23 is provided on the inner sliding member 21; A through groove 11 is opened on the main housing 10 along the first direction, and the second fixing column 23 is adapted to pass through the through groove 11;
[0048] Specifically, the outer adjustment component includes an outer adjustment member 32 and an outer sliding member 31 connected to the outer adjustment member 32. The outer sliding member 31 is slidably arranged on the outer wall of the main housing 10 along the first direction. The outer adjustment member 32 is adapted to adjust the position of the outer sliding member 31 in the first direction. A third fixing column 33 is provided on the outer sliding member 31;
[0049] Specifically, the brush component 40 includes an elastic main body portion 41 and a brush body portion 42 provided on the outer wall of the main body portion 41. Mounting portions 43 are provided at both ends of the main body portion 41, and the mounting portions 43 at both ends of the main body portion 41 are respectively mounted on two of the first fixing column 12, the second fixing column 23, and the third fixing column 33;
[0050] In some embodiments, the main body portion 41 may be in a long strip shape; in other embodiments, the main body portion 41 may also be in a circular ring shape;
[0051] In the above solution, the user selects a suitable brush assembly 40 according to the actual situation and assembles it on the first fixing post 12, the second fixing post 23 and the third fixing post 33 to form an annular or figure-eight structure. In the initial state, it is in an elliptical and slender state, and at this time, it can easily extend into the bottle to be cleaned, especially some round-bottom flasks. When the brush assembly 40 enters the bottle, at this time, the deformation of the brush assembly 40 can be controlled by adjusting the outer adjusting member 32 and / or the inner adjusting member 22, so that it deforms laterally from the slender state to be able to fit on the inner wall of the bottle, thereby realizing the cleaning inside the bottle; in this solution, the brush assembly 40 with a variable circular ring shape can increase its contact area with the inner wall of the bottle, thereby realizing a better cleaning effect, improving the cleaning efficiency and cleaning quality; at the same time, it also better solves the problem that it is difficult to clean the round-bottom flask with a small mouth and a large bottle body; in addition, in this solution, the installation position of the brush assembly 40 can be flexibly adjusted according to actual needs, and brush assemblies 40 of different sizes can be selected to adapt to the cleaning of various types of bottles, with strong use compatibility.
[0052] It can be understood that in some embodiments, the end of the inner adjusting member 22 may not exceed the end of the main housing 10, and groove patterns such as cross patterns are provided on the inner adjusting member 22 for easy adjustment; and when in use, the main housing 10 part is the main grasping part of the user; of course, in some other embodiments, the resin laboratory ware cleaning device provided in the present application can be connected to a driving mechanism, and through cooperation with mechanisms such as a clamping mechanism, a rotating mechanism, and a lifting mechanism, automatic adjustment can be achieved without manual cleaning.
[0053] Specifically, a first internal thread is provided on the inner wall of the main housing 10, and a first external thread is provided on the outer wall of the inner adjusting member 22, and the inner adjusting member 22 is in threaded cooperation with the inner wall of the main housing 10;
[0054] Further, one end of the inner adjusting member 22 close to the inner sliding member 21 is rotatably connected to the inner sliding member 21;
[0055] In the above solution, the user can adjust the relative position between the inner adjusting member 22 and the main housing 10 by rotating the inner adjusting member 22, and the inner adjusting member 22 is rotatably connected to the inner sliding member 21. Therefore, while the inner adjusting member 22 moves, it will drive the inner sliding member 21 to move, thereby adjusting the position of the second fixing post 23 to cause the brush assembly 40 to deform; this solution adopts a threaded adjustment method to realize the movement of the inner adjusting member 22 along the first direction, with a simple structure, convenient and quick adjustment, and at the same time, the stability of the position of the inner sliding member 21 can be ensured.
[0056] Specifically, a second external thread is provided on the outer wall of the main housing 10, and a second internal thread is provided on the inner wall of the outer adjusting member 32, and the outer adjusting member 32 is in threaded cooperation with the outer wall of the main housing 10;
[0057] Further, one end of the outer adjusting member 32 close to the outer sliding member 31 is rotatably connected to the outer sliding member 31;
[0058] In the above solution, the user can adjust the relative position between the outer adjusting member 32 and the main housing 10 by rotating the outer adjusting member 32. Since the outer adjusting member 32 is rotatably connected to the outer sliding member 31, when the outer adjusting member 32 moves, it will drive the outer sliding member 31 to move, thereby adjusting the position of the third fixing post 33 to cause the brush assembly 40 to deform. This solution uses a threaded adjustment method to achieve the movement of the outer adjusting member 32 in the first direction, with a simple structure, convenient and fast adjustment, and can ensure the stability of the position of the outer sliding member 31 at the same time.
[0059] It should be noted that the internal and external thread structure is a common structure, so it is not further shown in the drawings of this application, but it does not affect the understanding of those skilled in the art.
[0060] Specifically, a limiting groove 121 is provided on the outer peripheral wall of the first fixing post 12, the second fixing post 23, and the third fixing post 33, and the limiting groove 121 forms a ring around the axial direction of the column body;
[0061] In the above solution, the limiting grooves 121 formed on the first fixing post 12, the second fixing post 23, and the third fixing post 33 can hinder and limit the main body portion 41 of the card-in fixing post, improving the connection stability between the brush assembly 40 and the fixing post, and thus ensuring the stable progress of the cleaning process.
[0062] Specifically, through holes 431 are provided at the mounting portions 43 at both ends of the main body portion 41;
[0063] In the above solution, when assembling the brush assembly 40, the through holes 431 of the mounting portion 43 can be snapped onto the fixing post to achieve rapid installation. Under the hindering and limiting action of the limiting groove 121, the main body portion 41 can be stably connected to the fixing post.
[0064] It is understandable that in some embodiments, the connection may not be made by using the through holes 431, but by using a winding method for fixation; of course, other fixation methods that can achieve fixation can also be used, such as adding a covering structure at the end to achieve fixation, etc.
[0065] Specifically, please refer to Figure 1 , the first fixing post 12 is provided with one or two and is arranged along the first direction;
[0066] In the above solution, the first fixing post 12 is arranged near the end, so it is the fixing post with the highest usage probability. In this solution, it is limited to only one or two fixing posts. To fully consider the practicality of its actual use, in actual use, a certain adjustment space can be reserved for the two fixing posts. However, since it is not suitable to reserve too much space at the end, too many first fixing posts 12 cannot be fully utilized. Therefore, the number of the first fixing posts 12 is set to one or two in this solution.
[0067] Specifically, a plurality of second fixing posts 23 and third fixing posts 33 are provided and arranged along the first direction.
[0068] In the above solution, a plurality of second fixing posts 23 and third fixing posts 33 are provided. That is, in actual application, the user can flexibly adjust the assembly position according to the actual use requirements to achieve the adaptation to bottles of various sizes, and improve the use compatibility and flexibility.
[0069] Specifically, an elastic buffer head is provided at the first end of the main housing 10.
[0070] In the above solution, an elastic buffer head is further provided at the first end of the main housing 10, which can effectively reduce the impact when the end of the main housing 10 contacts the bottle, and further improve the safety of the cleaning process.
[0071] Specifically, limiting sliding grooves (not shown in the figure) are provided along the first direction on both the inner wall and the outer wall of the main housing 10, and the inner sliding member 21 and the outer sliding member 31 are provided with protrusions (not shown in the figure) adapted to the limiting sliding grooves.
[0072] In the above solution, the inner wall of the main housing 10 is in sliding fit with the inner sliding member 21, and the outer wall is in sliding fit with the outer sliding member 31. The limiting sliding grooves can prevent the inner sliding member 21 or the outer sliding member 31 from rotating during the adjustment process, and at the same time, the inner sliding member 21 and the outer sliding member 31 can be stably adjusted in position along the first direction. It can be understood that protrusions matching the sliding grooves are provided on the inner sliding member 21 and / or the outer sliding member 31, and the sliding fit is achieved through the protrusions and the limiting sliding grooves.
[0073] It should be noted that the sliding fit between the protrusion and the sliding groove is one of the common sliding fit methods, so the present application does not further elaborate on this structure.
[0074] It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other.
[0075] The above description is only for the preferred embodiments of the present application, and does not impose any formal restrictions on the present application. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present application all fall within the scope of the technical solution of the present application.
