Technical Field

[0001] The present application relates to the technical field of glass instruments, and in particular to an easy-to-clean flask. Background Art

[0002] The flask is an important laboratory glass instrument and is widely used in chemical experiments. It can be used for operations such as heating and reflux, and as a reaction vessel for various chemical reactions. By controlling the reaction conditions, such as temperature and pressure, various complex chemical reactions can be carried out in the flask to obtain the desired products.

[0003] In the field of scientific research, the application of flasks is becoming increasingly widespread. It not only plays an important role in the field of chemistry, but also involves many fields such as biology, medicine, and environmental science. By using flasks to conduct various experiments and research, scientists can gain an in-depth understanding of the properties of substances, reaction mechanisms, and life processes, etc., making important contributions to human scientific and technological progress and social development.

[0004] In the related art, a round-bottom flask is used as a container for chemical reactions. When a synthetic reaction involving a color such as a fluorescent dye is involved, after the reaction is completed, the inner wall of the round-bottom flask is easily adhered to the colored residue. At this time, the flask needs to be cleaned so that it can be reused next time.

[0005] However, a common round-bottom flask can only clean the bottom of the flask and the inner wall of the lower half of the flask body with a test tube brush, while the inner wall of the upper half of the flask body and the bottleneck are difficult to clean. To solve this problem, an easy-to-clean round-bottom flask is provided. Utility Model Content

[0006] In order to solve the problem that the inner wall of the upper half of the body and the bottleneck of the round-bottom flask in the related art are difficult to clean, the present application provides an easy-to-clean round-bottom flask.

The magnetic poles of the first strong magnetic circle and the second strong magnetic circle are opposite, so that the two can attract each other, thereby fixing the first bottle body and the second bottle body.

[0012] Preferably, the easy-to-clean round-bottom flask further comprises a rubber waterproof sleeve arranged at the connection between the first bottle body and the second bottle body.

[0013] By adopting the above technical solution: the rubber waterproof sleeve has good elasticity and sealing performance, and can effectively prevent liquid from leaking from the connection.

[0014] Preferably, a banding ring for enhancing sealing is provided on the outer side of the rubber waterproof sleeve.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-4 This application is described in further detail. Example

[0035] The present application embodiment discloses an easy-to-clean round-bottom flask, referring to Figure 1-Figure 4, comprising a first bottle body 1 and a second bottle body 2 arranged in sequence from top to bottom, a straight tube bottleneck 3 is installed on the top of the first bottle body 1, the straight tube bottleneck 3 and the interior of the first bottle body 1 are connected, and the height of the straight tube bottleneck 3 is 8 cm;

[0036] In addition, a connecting mechanism 4 is installed between the first bottle body 1 and the second bottle body 2. Figure 2 , Figure 3 and Figure 4 The first bottle body 1 is detachably connected to the second bottle body 2 by means of a connecting mechanism 4, wherein the connecting mechanism 4 is composed of a first waterproof edge 41 installed on the edge of the cut-off interface of the first bottle body 1, a second waterproof edge 42 installed on the edge of the cut-off interface of the second bottle body 2, a first strong magnetic circle 43 wrapped in the first waterproof edge 41, and a second strong magnetic circle 44 wrapped in the second waterproof edge 42, and the magnetic poles of the first strong magnetic circle 43 and the second strong magnetic circle 44 are opposite, so that the first bottle body 1 and the second bottle body 2 can be firmly combined by strong magnetism.

[0037] To enhance the sealing of the joint, refer to Figure 3 A rubber waterproof sleeve 5 is installed on a circle of outer wall at the connection between the first bottle body 1 and the second bottle body 2, and a tie ring 6 is used to tighten the connection at the outside of the rubber waterproof sleeve 5 to ensure the sealing performance;

[0038] At the same time, the opening diameter of the truncated interface of the first bottle body 1 is 0.2 mm smaller than the opening diameter of the truncated interface of the second bottle body 2, which enables the first bottle body 1 and the second bottle body 2 to form a tight fit when connected, further improving the sealing performance.

[0039] In addition, restrictions are imposed on the heights of the first bottle body 1 and the second bottle body 2, wherein the height of the first bottle body 1 is 4 cm, and the height of the second bottle body 2 is 6 cm. This size design ensures the overall stability of the flask while being convenient for users to hold and operate.

[0040] In order to facilitate the hanging and fixing of the round-bottom flask, a hanging ring 7 is installed on one side of the outer wall of the straight tubular bottleneck 3. The user can conveniently fix the flask in a suitable position through the hanging ring 7. At the same time, a through hole 8 is penetrated through the straight tubular bottleneck 3 near the bottle mouth. The through hole 8 can be used as a gas discharge port to reduce the pressure in the flask.

[0041] The working process and implementation principle of the embodiment are as follows: after the chemical reaction is completed and the product is collected, the inner wall of the round-bottom flask is stained with a moderate amount of residue that is difficult to clean. At this time, the round-bottom flask needs to be cleaned. Since the first bottle body 1 and the second bottle body 2 are detachably connected through the connecting mechanism 4, the user can easily disassemble the two bottle bodies when cleaning the flask and thoroughly clean the inside, which solves the problem that traditional flasks are difficult to clean thoroughly. Moreover, since the height of the first bottle body 1 is smaller than the height of the second bottle body 2, the hard-to-clean places such as the inner wall of the upper half of the flask and the bottleneck can be easily cleaned by disassembly.

[0042] The first waterproof edging 41 and the second waterproof edging 42 in the connecting mechanism 4, as well as the first strong magnetic circle 43 and the second strong magnetic circle 44 wrapped therein, not only ensure the stability of the bottle body connection, but also enhance the sealing performance of the connection. The strong magnetic attraction makes the first bottle body 1 and the second bottle body 2 tightly combined and not easy to separate. At the same time, the design of the waterproof edging also prevents liquid from leaking from the connection.

[0043] In addition, the use of the rubber waterproof sleeve 5 and the wrapping ring 6 further enhances the sealing of the joint, ensuring that the flask will not leak during use. The design of the tight fit between the first bottle body 1 and the second bottle body 2 also further improves the sealing effect.

[0044] When using the flask, the user can conveniently add or remove reagents through the straight tubular bottleneck 3, and the design of the hanging ring 7 allows the flask to be conveniently fixed and hung. At the same time, the through hole 8 on the straight tubular bottleneck 3 can be used as a gas discharge port, which helps to reduce the pressure in the flask and prevent safety problems caused by excessive pressure.

[0045] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
