Description

Technical Field

[0001] The present invention relates to the field of experimental equipment, and in particular to an experimental device for providing a stable temperature environment by heating water. Background Art

[0002] Currently, the metal bath shell on the market is made of sheet metal. Due to the limitation of the process, the outer shape can only be square or rectangular, with a single shape and lack of beautiful curves.

[0003] Since a stable temperature environment is provided by heating water, the water temperature will be consumed over time after it rises. The metal baths on the market do not have a liquid level observation window, so the amount of water cannot be seen at any time. Low water will affect the effect of the water bath. Moreover, the heating device and liquid level sensor of the water bath pot on the market are both inside the inner tank of the water bath pot, immersed in water. Both occupy a certain space, which in disguise reduces the space for the experimental beaker, which is not conducive to heating the beaker. The water bath pots on the market do not have obvious breathing lights to indicate heating and heating completion, and cannot prompt the operator of the equipment status. Most water bath pots on the market use the method of tilting the equipment to drain water, which is inconvenient to drain because the equipment is heavy.

[0004] The above defects of the prior art lead to the following technical problems: (A) The sheet metal structure has a single appearance; (B) It is impossible to observe the amount of water inside the equipment when the equipment is running; (C) The heating tube and the liquid level sensor occupy the space of the experimental beaker; (D) The operator cannot know the operating status of the equipment (including heating, heating completion, error alarm); (E) The heavy equipment must be tilted to drain the water from the inner tank. Summary of the invention

[0005] In view of the above problems, the present invention proposes an experimental device that provides a stable temperature environment by heating water, which can overcome the above shortcomings of the prior art: An experimental device for providing a stable temperature environment by heating water, comprising an inner liner for loading liquid, the inner liner being placed in an outer shell; A furnace ring assembly is provided on the top of the inner tank, and the furnace ring assembly includes a plurality of furnace rings that can be adapted to beakers of different calibers. A container bracket for supporting the beaker is provided in the inner tank, and the container bracket is located below the furnace ring assembly. A heating tube is provided at the bottom of the inner tank; The top of the inner tank is detachably connected to the outer frame, and a control panel is provided at one end of the outer frame. The control panel is electrically connected to the main control circuit board, and an inner tank sealing strip is provided between the inner tank and the outer frame to isolate the inside and outside of the experimental device, and prevent water vapor from entering the outside of the inner tank from the gap between the inside of the inner tank and the outer frame, that is, between the shell and the inner tank, and then damaging the circuit board, etc., thereby protecting the internal circuits, components, etc. The inner tank is loaded with hot water, which is heated by the heating tube so that the hot water reaches or maintains the required temperature level.

[0006] Preferably, the experimental device further comprises a window mechanism for observing the liquid level in the inner tank, the liquid level window mechanism comprises a window baffle and a liquid level observation window, and the liquid level observation window is arranged at the front end of the window baffle.

[0007] Preferably, the window shielding plate is connected to the inner liner through a pressing plate, and the inner liner is provided with a sealing ring surrounding the pressing plate, and the pressing plate is located between the window shielding plate and the sealing ring.

[0008] Preferably, an opening one is provided on the side of the inner tank, and an opening two is provided on the side of the outer shell, and the opening one is aligned with the opening two; the liquid level observation window is detachably connected to the opening two, the window baffle and the pressure plate are detachably connected to the edge of the opening one, and the sealing ring is tightly attached to the edge of the opening one.

[0009] Preferably, the liquid level observation window is snap-connected or threadedly connected to the opening.

[0011] Preferably, the top of the inner liner is connected to a furnace ring support plate, and the furnace ring support plate is provided with a round mouth for the beaker to pass through, and the furnace ring assembly is placed on the edge of the round mouth, or the furnace ring assembly is detachably connected to the edge of the round mouth. The round mouth surrounds the outside of the beaker passing through it, which can play a certain role in preventing water vapor from overflowing and reducing water loss. However, because there is a situation where the diameter of the beaker is smaller than the round mouth, the furnace ring assembly is used to adapt to beakers of different diameters to minimize the gap between the furnace ring and the beaker, so that water vapor can be prevented from overflowing from the gap. After the furnace ring is provided, the water vapor encounters the furnace ring and solidifies, and then drips into the inner liner again, so the furnace ring assembly mainly functions to prevent water vapor from overflowing and reducing water loss. The furnace ring support plate, the furnace ring assembly and the outer shell can ensure that the inner liner is in a protected and heat-insulating environment.
