DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0019] Embodiment 1:

[0020] Reference Figure 1-Figure 3 , an oil-splash-proof oil bath heating pot, comprising a control base 1, a controller 101 and an alarm light 102 are arranged on the control base 1, an oil bath pot body 2 is arranged on the control base 1, a first oil level sensor 201 and a second oil level sensor 202 are arranged on the oil bath pot body 2, the sensing ends of the first oil level sensor 201 and the second oil level sensor 202 are both located in the oil bath pot body 2, the first oil level sensor 201 is higher than the second oil level sensor 202, a baffle 203 is symmetrically arranged on the upper end of the oil bath pot body 2, an oil storage cylinder 3 is arranged on one side of the oil bath pot body 2 on the control base 1, an oil pump 4 is arranged between the oil bath pot body 2 and the oil storage cylinder 3, the oil inlet and outlet ends of the oil pump 4 are connected to the oil storage cylinder 3 and the oil bath pot body 2 respectively through oil pipes, a fixing component for fixing a test bottle is arranged on the control base 1, the first oil level sensor 201, the second oil level sensor 202, the alarm light 102, and the oil pump 4 are all electrically connected to the controller 101;

[0021] The fixing assembly includes a support rod 103, the support rod 103 is located at a side of the control base 1 away from the controller 101, a mobile ring 5 is sleeved on the fixed rod 502, a clamping block 6 is arranged above the baffle 203, the clamping block 6 is connected to the mobile ring 5 through the fixed rod 502, a slot is provided on the clamping block 6, a bidirectional screw rod 602 is rotatably connected in the slot, a clamping plate 601 is threadedly connected to the bidirectional screw rod 602, and the bidirectional screw rod 602 extends out of the clamping block 6;

[0022] A bolt 501 is threadedly connected to one side of the moving ring 5 , and the bolt 501 abuts against the support rod 103 .

[0023] When the test bottle needs to be heated in an oil bath, the bottleneck of the test bottle is placed between the two clamping plates 601, and the bidirectional screw rod 602 is rotated. The clamping plate 601 moves to clamp and fix the test bottle, and the bolt 501 is rotated to move the bolt 501 to the side away from the support rod 103. Then, the movable ring 5 is moved to a suitable height, and the bolt 501 is rotated to abut against the support rod 103 to fix the movable ring 5. Then, oil is poured in, and the oil bath pot body 2 is started to stir and heat the oil, and the baffle plate 203 is covered. When the test bottle is heated in an oil bath, the oil splashing around is blocked by the baffle plate 203. As the oil bath heating time increases, the oil in the oil bath pot body 2 will gradually decrease. When the first oil level sensor 201 does not sense the oil, the signal is transmitted to the controller 101. The controller 101 controls the alarm light 102 to light up and emits a sound reminder. At this time, the experimenter The remaining time of oil bath heating is used to determine whether refueling is needed. If a long time is still needed, the experimenter controls the controller 101 to make the oil pump 4 work to transport the oil in the oil storage cylinder 3 to the oil bath pot body 2. If the experimenter's judgment is inaccurate, resulting in the oil content being lower than the height of the heating tube before the end, the second oil level sensor 202 does not sense the oil. At this time, the controller 101 controls the oil pump 4 to transport oil to the oil bath pot body 2 to avoid dry burning and damage to the heating tube. After the oil bath is over, the baffle 203 is removed, the two-way screw 602 is rotated, the test bottle is removed, and oil bath heating is realized. Compared with the existing oil bath heating pot, the baffle 203 is used to block the splashing oil, and the first oil level sensor 201 and the second oil level sensor 202 are used to monitor the oil in the oil bath pot body 2 to avoid dry burning and damage to the heating tube, thereby effectively improving the safety of the equipment.

[0024] Embodiment 2:

[0025] Reference Figure 1-Figure 3 , an oil bath heating pot for preventing oil splashing, which is basically the same as Example 1, and further, an annular slot is opened at the upper end of the oil bath pot body 2, and plug blocks 204 are symmetrically arranged in the annular slot, and the plug blocks 204 are fixedly connected to the baffle 203. By inserting the plug blocks 204 into the slot, the baffle 203 is limited and fixed to prevent the baffle 203 from sliding off the oil bath pot body 2 and affecting the effect of preventing oil splashing.

[0026] A cooling plate 205 is provided at the lower end of the baffle 203. After the oil bath is finished, the oil needs to be left to cool down before the equipment can be managed. The controller 101 controls the oil bath body 2 to stir, and at the same time, the cooling plate 205 on the baffle 203 works, so that the oil in the oil bath body 2 cools down quickly, reducing the cooling time of the oil and effectively improving the cleaning rate of the equipment.

[0027] The oil storage cylinder 3 is hingedly connected with a cover plate 301, which is convenient for observing the oil content in the oil storage cylinder 3 so as to add oil in time.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
