Description

Technical Field

[0001] The utility model belongs to the technical field of constant temperature water bath equipment, in particular to a constant temperature water bath box. Background Art

[0002] Constant temperature water bath equipment 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, medical, health, biochemical laboratories, analysis rooms, education and scientific research.

[0003] Existing constant temperature water bath equipment usually places containers such as beakers directly in the water bath container. When a beaker with a larger bottom area is used for water bath heating, its bottom surface directly contacts the bottom of the water bath container, resulting in a lack of heated water between the bottom of the beaker and the bottom of the container, causing uneven heating of the bottom of the beaker, which has an adverse effect on the constant temperature heating effect. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model provides a constant temperature water bath, which can effectively improve the heating uniformity of the test substance and help to improve the reaction effect.

[0005] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0006] A constant temperature water bath box comprises: an outer shell and a water bath container arranged inside the outer shell, wherein a heating coil is arranged inside the outer shell corresponding to the outside of the water bath container.

[0007] The water bath container is a cylindrical structure and is rotatably arranged around an axis. An annular disk is coaxially arranged on the top of the water bath container. The inner diameter of the annular disk is smaller than the inner diameter of the water bath container. The water bath container is driven by a motor.

[0008] The outer shell is provided with a plurality of groups of connecting parts in a circular array along the circumference. The connecting parts are all arranged to move along the normal direction of the water bath container. The connecting parts are located above the annular disk, and a circular ring is provided at the front end of the connecting parts. The inner diameter of the circular ring is larger than the outer diameter of the beaker body and smaller than the outer diameter of the outer convex edge of the top of the beaker. The distance between the top surface of the circular ring and the bottom surface of the water bath container is larger than the height of the beaker. The circular ring is located within the inner circle of the annular disk, and the axis of the circular ring is parallel to the axis of the annular disk.

[0009] The beneficial effect of the utility model is that by rotating the water bath container and using the water bath container to drive the beaker to rotate, not only the heating uniformity of the heating medium can be improved, but also the heating uniformity of the reaction material can be improved, and the heating efficiency can be effectively improved.

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0015] like Figure 1 , Figure 2 As shown, a constant temperature water bath box comprises: a shell 1 and a water bath container 2 arranged inside the shell 1, and a heating coil 11 is arranged inside the shell 1 corresponding to the outside of the water bath container 2.

[0016] Specifically, Figure 1 , Figure 2 As shown, the water bath container 2 is a cylindrical structure and is rotatably arranged around an axis. An annular disk 21 is coaxially arranged on the top thereof. The inner diameter of the annular disk 21 is smaller than the inner diameter of the water bath container 2. The water bath container 2 is driven by a motor 22.

[0017] Specifically, Figure 1 , Figure 2 As shown, the shell 1 is provided with a plurality of groups of connecting members 12 in a circumferential array, and the connecting members 12 are all arranged along the normal movement of the water bath container 2. The connecting members 12 are located above the annular disk 21, and a circular ring 13 is provided at the front end of the connecting members 12, whose inner diameter is larger than the outer diameter of the beaker body and smaller than the outer diameter of the outer convex edge of the top of the beaker. The distance between the top surface of the circular ring 13 and the bottom surface of the water bath container 2 is larger than the height of the beaker, so that when the beaker is placed inside the circular ring 13, there is a gap between the bottom of the beaker and the bottom of the water bath container 2. The circular ring 13 is located within the inner circle of the annular disk 21, and the axis of the circular ring 13 is parallel to the axis of the annular disk 21.

[0018] When in use, a beaker filled with liquid is inserted into the ring 13, and the connecting piece 12 is moved outward so that the outer wall of the beaker is in contact with the inner ring of the annular disk 21, and the water bath container 2 is driven to rotate by the motor 22. During the rotation process, the water bath container 2 drives the beaker to move and rotate through the inner ring of the annular disk 21. This method not only stirs the heating medium inside the water bath container 2, but the beaker also acts as a stirring paddle, so that the heating medium in the water bath container 2 is heated more evenly; and the beaker itself is also rotating continuously, so as to shake the test substance inside the beaker, which not only makes it more evenly heated, but also increases the reaction speed, and there is no need for manual shaking operation; and the connecting piece 12 is moved to the middle part of the water bath container 2, so that the beaker and the annular disk 21 can be separated, so that the transmission is cut off, and the beaker will automatically stop rotating, so that the beaker can be taken out.

[0019] Preferably, Figure 2 As shown, the motor 22 is coaxially arranged at the bottom of the housing 1 .

[0020] Preferably, Figure 1 As shown, the connecting member 12 includes two parallel guide rods 121, the rear ends of which are both penetrated through the side walls of the housing 1. The two parallel guide rods 121 are connected to the housing 1, which can effectively improve the stability of the position of the ring 13 to prevent the ring 13 from swinging along the horizontal plane.

[0021] Further preferably, Figure 1 , Figure 2 As shown, the outside of the guide rod 121 is sleeved with a cylindrical spring 122, and the cylindrical spring 122 is located between the rear end of the guide rod 121 and the outer wall of the shell 1. When the cylindrical spring 122 is in a natural state, the distance between the ring 13 and the side wall of the shell 1 is the smallest. Therefore, when the beaker is placed in the ring 13, the cylindrical spring 122 will automatically make the beaker and the inner wall of the annular disk 21 close to each other to ensure that there is sufficient friction between the annular disk 21 and the beaker to drive the beaker to rotate.

[0022] Further preferably, Figure 1 , Figure 2 As shown, the guide rods 121 are sleeved with rollers 123 which are in rolling contact with the top surface of the annular disk 21 so as to support the guide rods 121 with the annular disk 21 to prevent the front end of the guide rods 121 from falling.

[0023] Preferably, Figure 1 , Figure 2 As shown, the inner ring of the annular disk 21 is provided with a rubber ring 211 to prevent the beaker from being damaged and to increase the friction between the annular disk 21 and the beaker to prevent the beaker from slipping.

[0024] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
