[0003] Currently, during the process of conducting pharmaceutical experiments, we found that there are some problems with the existing heating mantles during use. For example: during the experiment, we need to obtain the temperature value of the beaker heating, but most of the current heating mantles only display the voltage. When obtaining the heating temperature, it needs to be calculated, and during the experiment, there is often no time to perform the calculation, which leads to the problem of inconvenient acquisition of the temperature value when using the current heating mantles; during the experiment, we need to rotate the heating mantle so that the position where the temperature is displayed faces the operator to facilitate the operator to obtain the temperature value of the beaker heating, but none of the current heating mantles are provided with a rotating structure. When rotating, it can only be rotated by picking up the whole. During the experiment, the operator usually needs to operate multiple utensils simultaneously and often cannot complete this rotation process. At the same time, this rotation method may cause the beaker on the heating mantle to fall off when rotating the heating mantle.

The rotating base 20 is used to realize the rotation of the electric heating sleeve main body 10;

[0036] The electric heating sleeve main body 10 includes a heating component 100 and a control component 101. The heating component 100 is arranged on the top of the control component 101 and is detachably connected to the control component 101. The heating component 100 is used to heat the liquid in the beaker, and the control component 101 is used to control the heating component 100;

[0037] The heating assembly 100 is provided with a temperature sensor 102 inside. The temperature sensor 102 is used to sense the temperature inside the heating assembly 100. On one side of the control assembly 101, there is a display 103, and the display 103 is used to display the temperature value sensed by the temperature sensor 102.

[0038] By setting the temperature sensor 102 and the display 103, in use, the temperature inside the heating assembly 100 can be directly displayed through the temperature sensor 102 and the display 103. Compared with the traditional electric heating sleeve that displays voltage, the present utility model does not require calculation and can directly obtain the temperature value, solving the problem that it is inconvenient to obtain the temperature value when the current electric heating sleeve is in use.

[0039] The temperature sensor 102 is connected to the display 103 and is used to display the temperature inside the heating assembly 100.

[0040] The temperature sensor 102 can adopt the PT100 series of temperature sensors 102 in the prior art that can achieve the functions of the present utility model.

[0041] The display 103 can adopt an LED or LCD screen in the prior art.

[0042] As Figure 2 shown, in order to facilitate heating the liquid in the beaker, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the heating assembly 100 includes a housing 104, a heating inner sleeve 105, and a heat insulation bottom plate 106.

[0043] As Figure 4 shown, among them, the housing 104 is in a frustum shape. An installation ring 108 is provided at the top of the housing 104. The installation ring 108 is arranged at the top of the heating cavity 107 and is integrally formed with the housing 104. An installation part 109 that cooperates with the installation ring 108 is provided on the heating inner sleeve 105. The installation part 109 is detachably connected to the installation ring 108.

[0044] As Figure 3 shown, the installation part 109 includes a pair of clamping rings 110. The outside of the heating inner sleeve 105 is arranged between the pair of clamping rings 110. The pair of clamping rings 110 are detachably connected by bolts.

At the same time, when the liquid in the beaker splashes on the heating inner sleeve 105, the heating inner sleeve 105 can be removed and dried, which facilitates the use of the present utility model.

[0046] As Figure 6 shown, in order to facilitate the heating of the liquid in the beaker, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the heating inner sleeve 105 is hemispherical. The heating inner sleeve 105 includes a first insulating layer 111, a heating layer 112, and a second insulating layer 113 arranged in sequence. The materials of the first insulating layer 111 and the second insulating layer 113 are both non-alkali glass fibers, such as: aluminosilicate cotton, and the material of the heating layer 112 is a metal heating wire, such as: Cr20Ni80.

[0048] During use, the hemispherical heating inner sleeve 105 can fit more closely to the bottom of the beaker, thereby increasing the contact area and further improving the heating efficiency.

[0049] As Figure 4 shown, in order to facilitate the installation or removal of the heating inner sleeve 105, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a first fixing ring 114 is provided at the bottom of the housing 104, and a second fixing ring 115 is provided on the heat insulation bottom plate 106 and is arranged in cooperation with the first fixing ring 114. The first fixing ring 114 and the second fixing ring 115 are detachably connected by bolts.

[0052] As Figure 5As shown, the control component 101 includes a housing 116 and an operation panel 117.

[0055] As Figure 10 shown, the control unit 121 can adopt the temperature control unit used in the electric heating mantle in the prior art. The control circuit between the control unit 121 and the heating inner sleeve 105 can refer to the control circuit of the temperature control unit and the heating unit in the electric heating mantle in the prior art.

[0056] The control unit 121 should at least include a central controller, and the central controller can adopt a single-chip microcomputer that can realize the functions of the present utility model in the prior art.

[0057] As Figure 4 shown, in order to facilitate the installation or disassembly of the housing 116 and the heat insulation bottom plate 106, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a third fixing ring 118 is provided at the top of the housing 116, and a fourth fixing ring 119 is provided on the heat insulation bottom plate 106 and is arranged in cooperation with the third fixing ring 118.

[0059] During the experiment, we need to rotate the electric heating mantle so that the position where the temperature is displayed faces the operator, which is convenient for the operator to obtain the temperature value of the beaker heating. However, the current electric heating mantles are not provided with a rotating structure. When rotating, it can only be rotated by picking up the whole. During the experiment, the operator usually needs to operate multiple utensils at the same time and often cannot complete this rotation process. At the same time, this rotation method may cause the problem that the beaker on the electric heating mantle falls off when rotating the electric heating mantle.

[0060] As Figure 2 , Figures 7 to 9 shown, in order to solve this technical problem, in this embodiment, changes are made on the basis of the above embodiment.

The rotating seat 201 is rotatably connected to the fixed seat 200 through the rotating bearing 205. A first rotating groove 206 is provided on the rotating seat 201 and is arranged in cooperation with the first ring body 203.

[0061] Preferably, rotating handles 122 are provided on both sides of the housing 116. The rotating handles 122 are fixedly connected to the housing 116.

[0062] During use, the control component 101 and the heating component 100 can be rotated on the rotating base 20 by rotating the rotating handles 122, so that the display 103 can be rotated to face the operator, and rotation can be completed without the need to pick up the whole thing, solving the problem that the current electric heating sleeve needs to be picked up as a whole to rotate and the beaker may fall during the rotation process.

[0063] As Figure 5 , Figure 9 shown, in order to facilitate the connection between the control component 101 and the rotating base 20, in this embodiment, changes are made on the basis of the above embodiment. The difference from the above embodiment is that a fifth fixing ring 208 is provided on the rotating seat 201. A sixth fixing ring 120 is provided at the bottom of the housing 116 and is arranged in cooperation with the fifth fixing ring 208.

[0066] The utility model is provided with a temperature sensor 102 and a display 103. When in use, the temperature inside the heating component 100 can be directly displayed through the temperature sensor 102 and the display 103. Compared with the traditional electric heating sleeve that displays voltage, the utility model does not need to perform calculations and can directly obtain the temperature value.

[0067] The above embodiments only express the specific implementation manners of the utility model, and the description thereof is relatively specific and detailed.
