[0020] The technical scheme in the embodiment of the utility model will be described clearly and completely below. The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification, so that people familiar with this technology can understand and read them, and are not used to limit the limiting conditions that can be implemented in the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effect that can be produced by the utility model and the purpose that can be achieved, should still fall within the scope that the technical content disclosed in the utility model can cover. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of narration, and are not used to limit the scope that can be implemented. The change or adjustment of the relative relationship, without substantial change of the technical content, should also be regarded as the scope that can be implemented in the utility model.

[0021] See also Figures 1 to 4 An online titanium heater includes a heating cylinder 1, and the upper and lower ends of the heating cylinder 1 are respectively provided with a liquid inlet 2 and a liquid outlet 3. The heating cylinder 1 adopts a conventional cylindrical structure, with the upper end being the liquid inlet 2 and the lower end being the liquid outlet 3, both of which are conventional settings. At the same time, the liquid inlet 2 and the liquid outlet 3 are connected to an external pipe through a flange, and the existing spirally connected liquid inlet 2 and the liquid outlet 3 are convenient to install, and water leakage caused by wear of the threaded structure is avoided.

[0022] A plurality of heating tubes 4 are arranged in the heating cylinder 1. The heating tubes 4 are arranged in a vertical direction in the heating cylinder 1, and the heating tubes 4 are U-shaped tubes. The heating tubes 4 are arranged at intervals, and a junction box 5 is provided at the upper end of the heating cylinder 1, and the top port of the heating tube 4 extends into the junction box 5. The heating tubes 4 are evenly distributed along the circle where the center of the heating cylinder 1 is located, and the bottoms of the heating tubes 4 are staggered and stacked. Preferably, the number of heating tubes 4 used in this embodiment is 6, and the U-shaped through-setting is used to ensure the contact area with the liquid, and at the same time, the internal heating effect is evenly distributed, thereby improving the heating power.

[0023] There are two titanium tubes in the heating cylinder 1, one of which is provided with a temperature sensor, and the other is provided with an overheat protection switch. It is usually set to 115°C, and it is turned on when the temperature is lower than this, and it is disconnected when the temperature is higher than this, and the overheat protection switch can be self-recovering. Other temperature sensors can also be added, which will not be described here.

[0024] The junction box 5 and the heating cylinder 1 are connected and formed by glue pouring. The glue pouring integrated connection structure is stable and has a good sealing effect, thereby ensuring the effectiveness of the heating cylinder 1.

[0025] The material of the heating cylinder 1 and the heating tube 4 is titanium. Titanium has higher mechanical strength than the plastic heater shell. Therefore, under the same volume, the heating power can reach more than ten times that of the plastic heater. When the diameter of the heating cylinder 1 is 85mm and the length is 800mm, the heating power can reach 28kw.

[0026] Different from the prior art, the in-line titanium heater of the utility model optimizes the structure of the internal heating tube, more heating tubes can be arranged in the same volume, the heating power is increased, and the heating effect is improved.
