Problems solved by technology

Due to the small design of the bottle mouth of the flask, the traditional flask needs to use a drainage rod when adding liquid. During the operation, the chemical reagents are likely to splash out of the flask, causing chemical accidents. After the chemical reaction is over, cleaning the flask is a very tedious task. , the bottle mouth is thin and the bottle body is long, so it is difficult to clean the flask comprehensively. If there is a large solid reactant in the process of chemical reaction, the solid reactant must be ground and added, and the operation is very cumbersome. Secondly, in the prior art Even if the flask has an anti-splash device, there is still the possibility of liquid splashing, which poses a certain safety hazard

Embodiment 1

[0016] It can be seen from the accompanying drawings that a new type of anti-splash flask device includes: an upper body 1, a lower body 2, an anti-splash drainage plate 3, and a rubber sealing ring 4. The upper body 1 and the lower body 2 are connected by threads, and the anti-splash drainage plate 3 is fixed at the bottle mouth of the upper body 1, and there is a sealing device 4 at the connection between the upper body 1 and the lower body 2; the splash-proof flask device also includes a water absorbing device 5, which is arranged on the sealing device. During use, directly pour the reaction reagent into the flask, and the anti-splash drainage plate 2 will guide the reagent to the inner wall of the flask, and the reagent will slowly flow to the bottom of the bottle along with the inner wall, without the need for a drainage rod, which completely solves the problem of liquid splashing out of the flask The problem is that after the reaction is over, the upper body 1 and the low...

Embodiment 2

[0018] As an improvement of the present invention, the water absorbing device 5 is provided as at least one sponge layer. It can also be set to multiple layers, even if there is liquid splashing, it can prevent the liquid from flying out, further eliminating potential safety hazards.

Embodiment 3

[0020] As an improvement of the present invention, the sealing device 4 is made of a heat-resistant rubber sealing ring. The chemical reaction is often accompanied by high temperature and gas collection. After adopting this design, the problem of gas flowing out from the connection between the upper body and the lower body can be solved . The rest of the structural features and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to a novel splashing-proof flask device. The novel splashing-proof flask device comprises an upper main body, a lower main body, a splashing-proof flow guiding plate and a rubber sealing ring, wherein the upper main body and the lower main body are connected by threads, the splashing-proof flow guiding plate is fixed at a flask mouth of the upper main body, and a sealing device is arranged at the junction of the upper main body and the lower main body. The splashing-proof flask device further comprises a water suction device, wherein the water suction device is arranged on the sealing device. The device has the advantages that the problem that flasks cannot contain bulk solid reactants is excellently solved, the problem of liquid splashing due to the fact that a flow guiding rod is required to be used during liquid adding is solved, and the problem that the flasks are difficultly cleaned after carrying out chemical experiments is also solved, so that the practicability is very strong.

Description

technical field [0001] The invention relates to a novel anti-splash flask device, which is a flask tool used in experiments or production, and belongs to the field of chemical glassware, in particular to a split-type anti-splash flask. Background technique [0002] The flask is one of the utensils commonly used in chemical experiments or chemical production processes. It is suitable for heating, mixing liquids, and performing related chemical reaction experiments. Due to the small design of the bottle mouth of the flask, the traditional flask needs to use a drainage rod when adding liquid. During the operation, the chemical reagents are likely to splash out of the flask, causing chemical accidents. After the chemical reaction is over, cleaning the flask is a very tedious task. , the bottle mouth is thin and the bottle body is long, so it is difficult to clean the flask comprehensively. If there is a large solid reactant in the process of chemical reaction, the solid reactant...
