Description

Technical Field

[0001] The utility model relates to the field of electric heating tubes, and more specifically, to an anti-dry burning protection structure for an electric heating tube. Background Art

[0002] When a hot water kettle is turned on, if there is no water inside or the water in the water bottle is burned dry due to the long-term operation of the electric heating tube, the dry burning of the electric heating tube will cause its own temperature to reach several hundred degrees, which may further lead to a short circuit or even combustion of the circuit, and thus cause serious safety accidents.

[0003] After retrieval, a Chinese patent with the application number 202320217367.3 discloses an anti-dry burning protection device for an electric heating tube. Through the setting of the protection component, the device can directly conduct the protection switch through the floating sliding plate and floating plate. When the water vapor evaporates, it will be directly cut off, effectively preventing dry burning. And the relevant structure can directly remove the embedding block from the card slot by removing the screw rod, which is convenient for disassembly and maintenance and easy for the staff to operate quickly.

[0004] Regarding the above technology, the inventor believes that when the device protects the electric heating tube, it directly cuts off the power supply of the electric heating tube. However, when the device is in use, it cannot monitor according to the height of the water inside the hot water kettle, so that the operator cannot judge the situation inside the hot water kettle.

[0005] Therefore, an anti-dry burning protection structure for an electric heating tube is proposed to solve the above problems. Summary of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an anti-dry burning protection structure for an electric heating tube to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the utility model provides the following technical solution: an anti-dry burning protection structure for an electric heating tube, including a power supply main body and an electric heating tube body arranged below it. It is characterized in that a monitoring mechanism is arranged in the middle part at the bottom end of the power supply main body. The monitoring mechanism includes multiple groups of fixing rods and a base arranged at the bottom of the fixing rods. The multiple groups of fixing rods are arranged in a circular shape, and there are gaps between the fixing rods. A floating ball is arranged inside the multiple groups of fixing rods, and a scanning mechanism for scanning and sensing the floating ball is arranged on the surface of one group of fixing rods. The scanning mechanism is electrically connected to an indicator lamp component arranged on the surface of the power supply main body.

[0008] Preferably, a pressure sensing device is arranged at the top end of the base, and the pressure sensing device is electrically connected to a buzzer arranged on the surface of the power supply main body.

[0009] Preferably, the scanning mechanism includes a first scanning and sensing device, a second scanning and sensing device, a third scanning and sensing device, and a fourth scanning and sensing device, and the internal mechanism of the scanning mechanism is electrically connected to the green indicator light, yellow indicator light, orange indicator light, and red indicator light provided in the indicator light assembly in sequence.

[0010] Preferably, a plurality of grooves are formed on the surface of one group of the fixing rods, and the first scanning and sensing device, the second scanning and sensing device, the third scanning and sensing device, and the fourth scanning and sensing device are sequentially arranged in the grooves from top to bottom.

[0011] Preferably, the surfaces of the fixing rods where the grooves are formed are all provided with heat-insulating transparent materials with good sealing performance.

[0012] Preferably, a protective net is provided at the bottom of the power supply main body, and the protective net is sleeved on the outer surface of the electric heating tube.

[0013] Technical effects and advantages of the present utility model:

[0014] Compared with the prior art, the present utility model uses the floating balls between multiple fixing rods to monitor the height of the water inside the hot water kettle, and uses the scanning mechanism provided on the surface of the fixing rods to feedback the height of the floating balls, and lights the corresponding indicator lights inside the indicator light assembly according to the results, so that the operator can intuitively understand the situation inside the hot water kettle. At the same time, when the floating ball contacts the pressure sensing device, the buzzer will be activated and the energy of the electric heating tube will be completely cut off.
