Description

Technical Field

[0001] This utility model relates to the field of experimental instrument technology, and in particular to a variable diameter flask heating mantle. Background Technology

[0002] Electric heating mantles are common laboratory instruments that use metal heating wires to heat containers. Their advantages, such as rapid heating, high temperature, and ease of operation, have led to their widespread use. Typically, electric heating mantles are used in conjunction with magnetic stirrers to agitate the medium within the container, ensuring uniform heating and promoting the reaction.

[0003] Heating mantles are primarily used to heat liquids, which are stored in flasks. The bottom of the flask is spherical, and the top is a narrow-necked tube. Therefore, heating mantles are often designed with a bowl-shaped structure to accommodate the spherical bottom of the flask, which ensures efficient heating. Currently used flasks vary in diameter from 33mm to 460mm depending on their capacity. Therefore, a single heating mantle cannot provide fixed heating for flasks of various sizes.

[0004] An existing invention patent application with publication number CN106807466A discloses a universal electric heating mantle for multi-size spherical beakers. In this design, the heating mantle includes four arc-shaped heating elements, which are evenly arranged within the insulation sleeve along its central axis. While the arc-shaped heating elements can be driven by screws to accommodate flasks of different sizes, a rotating base is required to rotate the flask to ensure uniform heating. However, the flask typically needs to be connected to pipes to receive the evaporating material or supported by an iron stand, which can cause structural interference, preventing the flask from rotating and hindering its application. Furthermore, if foreign objects enter the interior, cleaning is difficult, and this can easily cause interference with the screw adjustment mechanism. On the other hand, existing heating mantles often use alkali-free glass fiber heating wire woven into a single integrated structure, making it difficult to design as a separate unit.

[0005] A utility model patent with authorization announcement number CN207820258U discloses an electric heating mantle with a quick inner liner replacement function. In this design, the outer shell of the heating mantle is hollow and is equipped with a ceramic adapter, a ceramic heat-conducting pad, and a spring plate. This structure affects the installation of the internal insulation cotton of the heating mantle, i.e., the insulation cotton interferes with the ceramic heat-conducting pad. If the insulation cotton is not installed, there is a safety hazard due to high-temperature use. Another utility model patent with authorization announcement number CN219761349U discloses an electric heating mantle with an easy inner liner replacement function, but it also does not have a corresponding heat insulation mechanism.

[0006] It is evident that the current electric heating mantle still has many shortcomings and therefore urgently needs improvement. Utility Model Content

[0050] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0051] like Figures 1-10 As shown, the variable diameter flask heating mantle of this utility model includes a base 1, a first heat insulation cotton 2, a heating inner sleeve 3, a coupler 4, a second heat insulation cotton 5, a buckle 6, a controller 7, and a magnetic stirrer 8.

[0052] like Figures 1-6 As shown, the base 1 is a solid structure and has a groove 101; the first heat insulation cotton 2 is disposed on the inner wall of the groove 101; the heating inner sleeve 3 is detachably connected to the base 1 and fits the first heat insulation cotton 2; the socket 41 of the coupler 4 is disposed on the outer surface of the base 1, the plug 42 of the coupler 4 is electrically connected to the heating inner sleeve 3, and the plug 42 is plugged into the socket 41.

[0053] As described above, the base 1 is a solid structure with a groove 101, so that the first heat insulation cotton 2 can be stably installed in the groove 101.

[0054] The coupler 4 consists of two parts: a socket 41 and a plug 42. The socket 41 is set on the outer wall of the base 1. When the heating inner sleeve 3 is installed, the plug 42 on the heating inner sleeve 3 is plugged into the socket 41 to realize the power supply to the heating inner sleeve 3.

[0055] When installing the heating inner sleeve 3, the heating inner sleeve 3 will be supported by the first heat insulation cotton 2, which will achieve heat insulation while ensuring the stability of the structure.

[0056] By making the heating inner sleeve 3 a detachable structure, it is easy to replace heating inner sleeves 3 of different sizes, thereby enabling heating of flasks of different diameters and ensuring uniform heating of the flasks.

[0057] At the same time, this structure does not interfere with the flask connection pipeline, nor does it interfere with the iron stand for connecting and fixing the flask, making it more convenient to use;

[0058] On the other hand, the socket 41 of the coupler 4 is located on the outer surface of the base 1, and can be powered after being plugged into the plug 42 of the heating inner sleeve 3, without interfering with the installation of the first heat insulation cotton 2.

[0059] like Figure 6 As shown, the heating inner sleeve 3 includes a heating part 31 and an overlapping part 32. The heating part 31 is located in the groove 101, has a bowl-shaped structure, and is attached to the first heat insulation cotton 2. The overlapping part 32 surrounds the opening of the heating part 31 and overlaps the base 1. The overlapping part 32 is an annular rigid plate. The plug 42 is disposed on the overlapping part 32.

[0060] As described above, the heating inner sleeve 3 is divided into two parts: a heating part 31 and an overlapping part 32. The heating part 31 is used for heating, and the overlapping part 32 is used to overlap the base 1 and, together with the first heat insulation cotton 2, supports the heating inner sleeve 3.

[0061] The overlapping part 32 is provided with a plug 42, which is electrically connected to the heating part 31 to provide power.

[0062] To ensure structural stability, the lap joint 32 is designed as a ring-shaped rigid plate.

[0063] With this structure, the coupler 4 is located at the edge of the base 1 and the heating inner sleeve 3, which will not interfere with the installation of the first heat insulation cotton 2, nor will it interfere with the application of the stirring component in this electric heating sleeve.

[0064] like Figures 7-10 As shown, multiple heating inner sleeves 3 are provided, and the heating parts 31 of the multiple heating inner sleeves 3 are of different sizes. The second heat insulation cotton 5 is provided on the surface of the heating part 31.

[0065] As described above, in order to accommodate flasks of different diameters, multiple heating inner sleeves 3 are provided, and the heating parts 31 of the multiple heating inner sleeves 3 are of different sizes, so that the heating inner sleeve 3 can be selected for flasks of different diameters.

[0066] Specifically, for the smaller heating inner sleeve 3, a second heat insulation cotton 5 is provided to support the bottom of the heating inner sleeve 3. When assembling the heating inner sleeve 3, the second heat insulation cotton 5 is placed in contact with the first heat insulation cotton 2 to achieve support. This can prevent the heating inner sleeve 3 from deforming, thereby ensuring the heating effect of the heating inner sleeve 3.

[0067] like Figure 2 As shown, the buckle 6 is set on the base 1, and the buckle 6 is used to lock the heating inner sleeve 3;

[0068] As described above, the buckle 6 is used to connect and fix the base 1 and the heating inner sleeve 3, thereby preventing the heating inner sleeve 3 from becoming loose when a container is placed inside it.

[0069] like Figure 7 As shown, the buckle 6 includes a pull buckle 61, a sliding sleeve 62 and a pressure plate 63. The pull buckle 61 is disposed on the base 1; the sliding sleeve 62 is disposed on the base 1 and forms a sliding cavity with the base 1; the pressure plate 63 is slidably disposed in the sliding cavity, one end of the pressure plate 63 is connected to the pull buckle 61, and the other end presses against the overlapping part 32.

[0070] As described above, the latch 6 is provided with a pull tab 61, a sliding sleeve 62 and a pressure plate 63;

[0071] Both the buckle 61 and the sliding sleeve 62 are connected to the base 1, while the pressure plate 63 is slidably disposed in the sliding cavity between the base 1 and the sliding sleeve 62. Thus, when the buckle 61 is pulled, the pressure plate 63 moves synchronously to press and hold the overlapping part 32, thereby fixing the heating inner sleeve 3.

[0072] like Figure 7 As shown, the pressure plate 63 includes a first rigid section 631, a second rigid section 632, and an elastic section 633, wherein the first rigid section 631 and the second rigid section 632 are connected through the elastic section 633; ​​the end of the first rigid section 631 away from the elastic section 633 is connected to the pull buckle 61; the end of the second rigid section 632 away from the elastic section 633 presses against the overlapping portion 32; when the second rigid section 632 presses against the overlapping portion 32, the elastic section 633 is completely located within the sliding cavity;

[0073] As described above, the pressure plate 63 is divided into three parts. In specific applications, the first rigid section 631 is connected to the buckle 61, which adopts the pull part of a common hook and loop fastener.

[0074] When the buckle 61 pulls the first rigid section 631, it simultaneously drives the second rigid section 632 and the elastic section 633 to move. When the second rigid section 632 presses the overlapping part 32, the elastic section 633 must be completely located in the sliding cavity between the base 1 and the sliding sleeve 62. In this way, when the second rigid section 632 presses the heating inner sleeve 3 and causes it to be under force, it will not flip outward, but will be blocked by the sliding sleeve 62, thereby achieving the clamping and fixing of the heating inner sleeve 3.

[0075] Conversely, loosen the buckle 61 and pull the pressure plate 63 upward through the second rigid section 632 until the connection between the second rigid section 632 and the elastic section 633 moves out of the sliding cavity. Then the second rigid section 632 can be folded outward through the elastic section 633, and the heating inner sleeve 3 can be removed and replaced.

[0076] Specifically, during assembly, one of the latches 6 is set to correspond to the coupler 4, which can ensure a stable connection between the socket 41 and the plug 42 and ensure the stability of power supply.

[0077] The elastic segment 633 can play a certain buffering role, thereby avoiding damage to the coupler 4 caused by overvoltage.

[0078] like Figures 1-5 As shown, the controller 7 is mounted on the base 1 and is electrically connected to the socket 41;

[0079] As described above, the controller 7 is used for electrical control of this electric heating mantle and for adjusting the heating rate. It is a conventional component and will not be described in detail here.

[0080] To ensure a compact structure, the controller 7 is integrated with the base 1 into a single unit and is electrically connected to the socket 41 via a wire.

[0081] like Figure 3 As shown, the magnetic stirrer 8 is provided with a mounting groove 801, and the base 1 is disposed in the mounting groove 801;

[0082] As described above, by setting up a magnetic stirrer 8, the container inside the flask can be stirred, thereby achieving uniform mixing of the liquid and ensuring the continuation of the reaction.

[0083] To ensure the stability of the connection, the magnetic stirrer 8 is provided with a mounting groove 801 for accommodating the base 1;

[0084] Specifically, the magnetic stirrer 8 is a motor that drives the magnet to rotate. A magnetic rotor is placed inside the flask. When the motor drives the magnet to rotate, the magnet will drive the magnetic rotor inside the flask to rotate through magnetic force, thereby stirring the liquid in the flask by magnetic rotation, thus achieving the stirring function.

[0085] Specifically, when setting up a magnetic rotor for stirring, the heating temperature should be kept below 150°C to avoid failure of the magnetic rotor.

[0086] like Figure 2 As shown, the magnetic stirrer 8 is electrically connected to the controller 7;

[0087] As described above, in order to further ensure the compactness of the structure, the electrical components used to control the magnetic stirrer 8 are integrated into the controller 7. Thus, after the base 1 is placed on the magnetic stirrer 8, the magnetic stirrer 8 is connected to the controller 7 by wires to achieve power supply. This type of circuit integration technology is existing technology, so it will not be described in detail.

[0088] Specifically, the first heat insulation cotton 2 is high-pressure shaped heat insulation cotton; the heating inner sleeve 3 is a mesh structure formed by fiber strips and heating wires;

[0089] Specific implementation steps:

[0090] First, select a heating inner sleeve 3 with a suitable heating section 31 according to the required flask size. Place the heating inner sleeve 3 in the groove 101 of the base 1 and connect the plug 42 to the socket 41. Then place the flask on the heating section 31 and start heating through the controller 7.

[0091] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
