Description

Technical Field

[0001] This utility model relates to the field of heating element technology, and in particular to a two-section heating element that facilitates adjustment of power combinations. Background Technology

[0002] More and more drinking water and water purification products are equipped with hot water functions. Most existing drinking water and water purification products heat water using a heating element. Currently, two-stage heating elements on the market are divided into two fixed power sections on a single heating element. For example, a heating element with a total power of 2100W is divided into 1050W+1050W or 800W+1300W power combinations. This fixed power segmentation method has a significant drawback: the two power combinations are fixed and cannot be flexibly adjusted. Therefore, when the product function needs to adjust the power combination of the two sections of the heating element, it is necessary to replace or develop a new heating element, indicating room for improvement. Utility Model Content

[0003] The present invention aims to overcome the defects in the prior art and provide a two-stage heating element that facilitates the adjustment of power combinations. By setting at least two common end electrodes between the first and second electrodes of the heating tube, different power combinations can be easily obtained to meet different application scenarios by connecting the first and second electrodes and different common end electrodes.

[0004] To achieve the above objectives, this utility model provides a two-section heating element that facilitates adjustment of power combinations, including a heating tube. A first electrode and a second electrode are respectively provided at both ends of the heating tube, and at least two common end electrodes are also provided between the first electrode and the second electrode.

[0005] A further configuration is provided: a first temperature controller is provided between the first electrode of the heating tube and the adjacent common terminal electrode, and a second temperature controller is provided between the second electrode of the heating tube and the adjacent common terminal electrode.

[0006] The heating tube is further configured to be arranged vertically, with its lower end being the water inlet and its upper end being the water outlet.

[0007] The heating element is further configured to be a PTC ceramic tube.

[0008] The configuration is further defined as follows: each of the common terminal electrodes is marked with a corresponding power combination value.

[0009] Compared with the prior art, the present invention has a simple and reasonable structure. In the process of use, by connecting the first electrode, the second electrode, and different common terminal electrodes, different power combinations can be obtained from the same heating element to meet different application scenarios.

[0013] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0014] This utility model provides a two-section heating element that facilitates adjustment of power combinations, such as... Figure 1 As shown, the device includes a heating tube 1, with a first electrode 2 and a second electrode 3 respectively at both ends. At least two common end electrodes are arranged at intervals between the first electrode 2 and the second electrode 3. By connecting the first electrode 2, the second electrode 3, and different common end electrodes, the heating element can obtain different power combinations to meet different application scenarios. In actual use, the heating tube 1 is installed vertically, with the lower end of the heating tube 1 being the water inlet 11 and its upper end being the water outlet 12. This allows the heating tube 1 to be filled with water to reduce the generation of bubbles and avoid local high temperatures in the heating tube 1. The electrodes on the heating tube 1, from top to bottom, are the first electrode 2, common end electrode 1 41, common end electrode 2 42, common end electrode 3 43, and the second electrode 3. In this embodiment, the heating tube 1 is preferably a PTC ceramic tube.

[0015] In this embodiment, as Figure 1 As shown, a first temperature controller 5 is provided between the first electrode 2 and the adjacent common terminal electrode of the heating tube 1, and a second temperature controller 6 is provided between the second electrode 3 and the adjacent common terminal electrode of the heating tube 1. In this way, the first temperature controller 5 and the second temperature controller 6 can monitor the two sections of the heating tube 1 respectively, thereby effectively preventing the heating tube 1 from being damaged due to excessive temperature.

[0016] In this embodiment, each common terminal electrode is marked with a corresponding power combination value, so that users can more intuitively know the power combination corresponding to the common terminal electrode, and thus more conveniently select the correct common terminal electrode for connection to obtain the required heating element power combination.

[0017] Compared with the prior art, the present invention has a simple and reasonable structure. In the process of use, by connecting the first electrode, the second electrode, and different common terminal electrodes, different power combinations can be obtained from the same heating element to meet different application scenarios.

[0018] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
