Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature water bath pots, in particular to a super constant temperature water bath pot for preventing liquid from splashing. Background Art

[0002] Constant temperature water bath is widely used in drying, concentration, distillation, impregnation of chemical reagents, impregnation of medicines and biological preparations. It can also be used for water bath constant temperature heating and other temperature tests. It is an essential tool for biological, genetic, virus, aquatic, environmental protection, medicine, health, biochemical laboratories, analysis rooms, education and scientific research.

[0003] When using an existing constant temperature water bath, test tubes, beakers and other utensils are usually placed on a partition. After the constant temperature water bath completes heating of the utensils, tweezers are usually used to grip the utensils for removal. When gripping the utensils, the hands are relatively close to the constant temperature water bath. Since the water in the constant temperature water bath is at a high temperature just after heating, the liquid in the water bath is very likely to splash onto the hands of the staff when the utensils are taken out, which is dangerous and has low safety performance. In addition, the stability of the water bath is poor, which makes the water bath prone to bumps when moving. Utility Model Content

When in specific use, the pot cover 11 is used to block the internal heat loss during the heating process and has the function of preventing liquid splashing. The heating device 18 is externally connected to a power supply; the partition 12 is movably arranged in the water bath body 10 above the heating device 18, and a plurality of through holes are opened on it for placing the vessel to be heated; the first lifting rod 13 is rotatably arranged vertically in the water bath body 10, and the threaded section arranged at the upper end thereof is threadedly connected and penetrated with the first slider 121 arranged on the first side of the partition 12, and the lower end of the lifting rod penetrates the water bath body 10 and is driven by the driving assembly 20.

[0050] Specifically, the height of the threaded section on the first lifting rod 13 is a safe height at which the heating vessel can be raised and lowered, and the height of the partition 12 can be adjusted according to actual needs. After the heating is completed, the first lifting rod 13 is driven by the driving assembly 20 to rotate to lift the partition 12 and transport the experimental vessel to a higher position of the water bath body 10, so that the staff can take the vessel and avoid being splashed by hot air and liquid on their hands.

[0051] According to the instruction manual Figure 7 , 8 It can be seen that the guide rail 14 is vertically arranged on the side wall of the water bath body 10 and is slidably connected with the guide block 122 corresponding to the side of the partition 12; the limiting rod 31 is arranged in the channel 101 of the side wall of the water bath body 10, and is used to limit the partition 12. The wedge-shaped end 33 arranged at the first end of the limiting rod 31 passes through the channel 101 and then extends into the guide rail 14. The second end passes through the channel 101 and is provided with a limiting cap 32, and the wedge-shaped end 33 always faces upward; the boss 34 is arranged on the outer circumferential surface of the limiting rod 31 and is adapted to the channel 101; the first spring 35 is sleeved on the limiting rod 31, and its two ends are respectively abutted against the boss 34 and the bottom of the channel 101; a plurality of casters 15 are arranged on the bottom surface of the water bath body 10, and each caster 15 is connected to the water bath body 10 through a shock absorbing assembly 40.
