Description

Technical Field

[0001] This utility model relates to the field of beaker technology, specifically a water bath heating beaker. Background Technology

[0002] Beakers, as one of the basic tools in the laboratory, are widely used in various experiments and research due to their simple structure, ease of operation, and high-temperature resistance. Their versatility makes them play an important role in experiments, especially in operations such as chemical reactions, liquid heating, dissolution, and mixing.

[0003] However, when a traditional water bath is used to heat a beaker, the water evaporates into steam over time, causing continuous water loss that affects the temperature. This results in water waste, compromises temperature control, and reduces the accuracy and stability of the experiment. Utility Model Content

[0013] (III) Beneficial Effects

[0014] This utility model provides a water bath heating beaker, which has the following beneficial effects:

[0015] 1. In this utility model, when the liquid inside the outer beaker is heated, the evaporated water vapor cannot pass through the sealing ring. Instead, it condenses and flows back into the outer beaker, preventing the water vapor from evaporating into the air. The high-temperature water vapor will not damage the sealing ring, effectively reducing water vapor loss during heating and thus maintaining the stable volume of the liquid inside the outer beaker.

[0016] 2. In this utility model, the sealing component has two different structures. The sealing ring is an integral structure that can completely seal the gap between the outer beaker and the support plate. Multiple arc-shaped rings can be assembled into a whole to seal the gap. Furthermore, the arc-shaped ring can be removed individually to adjust the sealing area. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figures 1 to 7 This utility model provides a technical solution: a water bath heating beaker, including an outer beaker 1 and an inner beaker 2 disposed inside the outer beaker 1. Multiple connecting rods 4 are fixedly connected to the inner bottom wall of the outer beaker 1, and a support plate 3 is fixedly connected to the upper ends of the multiple connecting rods 4. The inner beaker 2 is disposed on the top of the support plate 3. A sealing component for sealing the gap between the support plate 3 and the outer beaker 1 is provided inside the outer beaker 1. Different types of liquids are placed inside the inner beaker 2 and the outer beaker 1, so that when the outer beaker 1 is heated, the liquid inside the inner beaker 2 is also heated synchronously. Alternatively, multiple outer beakers 1 can be used, nested sequentially, with the outermost outer beaker 1 being larger than the innermost one, thus allowing for the simultaneous heating of multiple liquids.

[0027] The sealing assembly has two different structures. In the first case, the sealing assembly includes a sealing ring 7 and two traction rods 8 fixed to the top of the sealing ring 7. The traction rods 8 are arranged symmetrically about the central axis of the sealing ring 7, and the upper end of the traction rod 8 has a bend.

[0028] When the liquid inside the outer beaker 1 is heated, the evaporated water vapor cannot pass through the sealing ring 7. Instead, it condenses on the surface of the sealing ring 7 and flows back into the outer beaker 1. The water vapor cannot evaporate into the air, and the high-temperature water vapor will not damage the sealing ring 7. This effectively reduces the loss of water vapor during heating, thereby maintaining the volume stability of the liquid inside the outer beaker 1.

[0029] The sealing ring 7 made of borosilicate has the characteristics of low thermal expansion coefficient, high thermal shock resistance and good chemical stability, which can effectively block water vapor evaporation at high temperature. The arc-shaped ring 9 described below is also made of borosilicate.

[0030] Secondly, the sealing assembly includes four arc-shaped rings 9 and a pull rod 10 fixed to the top of each arc-shaped ring 9. The four arc-shaped rings 9 can be spliced ​​together end to end to form a whole ring.

[0031] The sealing ring 7 is an integral structure that can completely seal the gap between the outer beaker 1 and the support plate 3; while multiple arc-shaped rings 9 can be assembled into a whole to seal the above gap, and the arc-shaped ring 9 can be removed individually to adjust the sealing area.

[0032] A second support ring 6 is fixedly connected to the inner wall of the outer beaker 1, and a first support ring 5 is fixedly connected to the outer circumferential side wall of the support disk 3. The first support ring 5 and the second support ring 6 are at the same horizontal height. The sealing ring 7 and multiple arc-shaped rings 9 are all set on the top of the first support ring 5 and the second support ring 6 to achieve the purpose of support.

[0033] The connecting rod 4 is inclined, and there are four connecting rods 4 distributed in a circle to provide stable support for the support plate 3, preventing the inner beaker 2 from tilting or becoming unstable due to uneven force.

[0034] The support plate 3 is set horizontally, and the top view area of ​​the support plate 3 is larger than the top view area of ​​the inner beaker 2, so that the inner beaker 2 will not affect the normal placement and removal of the sealing component after being placed on the surface of the support plate 3.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
