[0001] The utility model relates to the technical field of water bath experimental equipment, in particular to a water bath provided with a retractable supporting tube. Background Art

[0002] The water bath is mainly used for distillation, drying, concentration and warm soaking of chemicals or biological products in the laboratory. It can also be used for constant temperature heating and other temperature tests. It is an essential tool for biology, genetics, viruses, aquatic products, environmental protection, medicine, hygiene, laboratories, analysis rooms, education and scientific research. The stainless steel electric heating tube is placed horizontally in the water bath, and the middle shelf with holes is placed inside the water tank. The top cover is equipped with combined rings of different diameters to accommodate flasks of different diameters. A drain pipe is set on the side of the water bath.

[0003] When the existing water bath in the laboratory is used for water bath reaction, flasks, glasses and other containers are needed. At this time, a support frame needs to be placed next to the water bath to place, support, drain, etc. the flasks, glasses and other containers. When the area of ​​the laboratory table is limited, it is not convenient to place an independent support frame on the laboratory table.

[0004] Therefore, how to improve the structure of the water bath to solve the problem of adding support members, facilitate the use of support members to place, support, drain, etc. flasks, glasses and other containers, and solve the problem that traditional support frames occupy limited laboratory table area is a technical problem that technical personnel in this field urgently need to solve.

[0013] The air inlet of the heat exchange box is connected with the air outlet of the air pump through an air pipe, the air inlet of the air pump is connected with the air inlet through hole on the outer shell through the air pipe, and the air outlet of the heat exchange box is sealed and connected with the lower hole of the internal threaded through hole on the outer flange of the inner water tank through the air pipe. The heat exchange box, air pipe and air pump are all located in the sandwich cavity between the outer wall surface of the inner water tank and the inner wall surface of the outer shell, so that when the support tube is inserted and fixed in the internal threaded through hole, the air exhausted by the air pump is discharged from the air outlet on the support tube after heat exchange with the heat exchange fins through the heat exchange box, and then the hot air performs hot air drying on the container placed upside down on the support tube.

[0014] Preferably, the outer shell, inner water tank, top cover plate and support tube are all made of stainless steel, and the electric heating tube is a stainless steel electric heating tube.

[0015] The present application has achieved the following beneficial technical effects:

[0016] When flasks, glasses and other containers need to be placed, supported, drained, etc., the support tube of the water bath is released, and the support tube is installed at an angle perpendicular to the outer flange at the top opening of the inner water tank, and then the flasks, glasses and other containers are placed upside down on the support tube; when the support tube is used, the support tube is laid down horizontally, folded up and placed flat in the storage groove on the outer flange of the inner water tank;

[0017] The water bath has its own support tube, which is easy to use and does not require a separate support frame, so it does not occupy the surrounding space of the water bath. The water bath has its own support tube, which can be retracted to save space.

[0018] This not only solves the problem of adding support members, facilitates the use of support tubes to place, support, drain, etc. flasks, glasses and other containers, but also solves the problem of traditional support frames occupying limited laboratory table area.

[0025] Reference Figure 1-2 In the figure: outer shell 1, inner water tank 2, outer flange 201 at the top opening of the inner water tank, storage groove 202, electric heating tube 3, top cover plate 4, support tube 5, air outlet 501; heat exchange box 6, heat exchange fins 7, vacuum pump 8, air pipe 9.

[0026] The present application provides a water bath pot with a retractable support tube, comprising an outer shell 1, an inner water tank 2, an electric heating tube 3, a top cover plate 4 and a support tube 5;

[0027] The inner water tank 2 is placed in the outer shell 1, the electric heating tube 3 is placed in the inner water tank 2, and the top cover plate 4 is placed at the top opening of the inner water tank 2;

[0028] When the support tube 5 is in the released state, the support tube 5 is fixedly arranged on the outer flange 201 at the top opening of the inner water tank 2 in a vertical posture, the bottom of the support tube 5 is provided with an external thread, and the outer flange of the inner water tank 2 is provided with an internal threaded through hole, and the bottom end of the support tube 5 is detachably inserted into the internal threaded through hole fixed on the outer flange of the inner water tank 2 through a threaded connection;

[0029] When the support tube 5 is in the retracted state, the bottom end of the support tube 5 is unscrewed from the internal threaded through hole on the outer flange of the inner water tank 2, and the unscrewed and disassembled support tube 5 is placed in the storage groove 202 on the outer flange of the inner water tank 2.

[0030] In one embodiment of the present application, a plurality of air outlet holes 501 are provided on the tube wall of the support tube 5;

[0031] A hollow and airtight heat exchange box 6 is provided on the outer length and width surface of the bottom wall of the inner water tank 2, and a plurality of heat exchange fins 7 are welded on the outer length and width surface of the bottom wall of the inner water tank 2, and the heat exchange fins 7 are located in the heat exchange box 6;

[0032] The air inlet of the heat exchange box 6 is connected to the air outlet of the air pump 8 through the air pipe, the air inlet of the air pump 8 is connected to the air inlet through hole on the outer shell 1 through the air pipe, and the air outlet of the heat exchange box 6 is sealed and connected to the lower hole of the internal threaded through hole on the outer flange of the inner water tank 2 through the air pipe 9. The heat exchange box 6, the air pipe 9 and the air pump 8 are all located in the sandwich cavity between the outer wall surface of the inner water tank 2 and the inner wall surface of the outer shell 1;

[0033] When the support tube 5 is inserted and fixed in the internal threaded through hole, the air discharged by the vacuum pump 8 flows through the heat exchange box 6 and the heat exchange fins 7. The electric heating tube 3 generates heat after being energized to heat the water in the inner water tank 2. Then, the bottom tank wall of the inner water tank 2 is heated by the heated water. Then, the heat on the bottom tank wall is transferred to the heat exchange box 6 and the heat exchange fins 7, which are also made of stainless steel. Then, the heat on the heat exchange box 6 and the heat exchange fins 7 is transferred to the air output by the vacuum pump through heat exchange, turning the cold air into hot air. The hot air after heat exchange is discharged from the air outlet 501 on the support tube 5. Since the flasks, glasses and other containers need to be dried after washing, the hot air is used to dry the containers placed upside down on the support tube 5. The support tube 5 is used to place and support the flasks, glasses and other containers, and the hot air in the support tube 5 is used to dry the flasks, glasses and other containers. Obviously, actively blowing hot air to dry is faster than natural draining and natural drying, and the drying effect will be better.

[0034] In one embodiment of the present application, the outer shell 1, the inner water tank 2, the top cover plate 4 and the support tube 5 are all made of stainless steel, and the electric heating tube 3 is a stainless steel electric heating tube.
