Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a heat-generating belt and a liquid heater. Background Art

[0002] Liquid heaters use a heating element to heat the container, thereby heating the liquid inside. Because the container is in contact with water or other liquids, if the heating element leaks electricity, the current could be conducted through the container, liquid, or device casing, posing a risk of electric shock to the user.

[0003] The grounding structure effectively directs leakage current to the ground, reducing the risk of electric shock. Installing the grounding structure requires connecting the heating element via a ground wire. However, the heating element of the liquid heating container is sheet-shaped, making grounding difficult, reducing the assembly and production efficiency of the liquid heater.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field. Utility Model Content

[0005] In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a heat-generating belt and a liquid heater to improve the production efficiency of the liquid heater.

[0014] A further technical solution is that the two short sides of the shell are folded toward the same side to form a connecting portion; the connecting portion is connected and fixed by a fastener, and twisting the fastener drives the heat-generating belt to expand or contract.

[0015] The beneficial technical effects of the utility model are as follows:

[0026] Example 1

[0027] Figure 1 The figure shows a three-dimensional structural diagram of the heat-generating belt in the first embodiment of the present invention. Figure 2 FIG1 shows a partial enlarged view of the heat-generating belt at A in the first embodiment of the present invention. Figure 1 and Figure 2, heat-generating belt, the heat-generating belt 1 includes a heat-generating layer 11, an outer shell 12 and a grounding port 3. The heat-generating layer 11 is arranged in the outer shell 12 for protection. A raised piece 123 is provided on the outer shell 12. The grounding port 3 includes a connecting section 31 and an inserting section 33. A first flange 32 is provided on opposite sides of the connecting section 31. A second flange 34 is provided on opposite sides of the inserting section 33. Among them, the ground wire 2 extends between the connecting section 31 and the first flange 32, and the ground wire 2 is clamped by the connecting section 31 and the first flange 32; the raised piece 123 extends between the inserting section 33 and the second flange 34, and the raised piece 123 is clamped by the inserting section 33 and the second flange 34 to achieve grounding of the heat-generating belt 1. The connection mechanism of the ground wire 2 does not require the use of fasteners such as screws, and can be quickly assembled, reducing the production cycle. The procurement cost of screws and related tools is eliminated, reducing costs. Without exposed screws, the appearance of the heat-generating belt 1 is more simple and beautiful.

[0028] Please refer to Figure 1 and Figure 2 The thickness of the lift tab 123 where it connects to the housing 12 is reduced, and the bending rigidity is reduced, making it easier for the lift tab 123 to rotate around the housing 12 to adjust the angle. Adjusting the angle of the lift tab 123, and thus adjusting the angle of the ground wire 2 connected to the lift tab 123, facilitates the connection between the ground wire 2 and the housing 12, further improving the production efficiency of the liquid heater.

[0029] Preferably, the heating layer 11 includes a heating core and an insulating layer. The insulating layer wraps the heating core to prevent short circuit between the heating core and other conductors.

[0030] The lift tab 123 is formed by machining a U-shaped hole 125 in the housing 12 and then bending it, saving raw material for the heat-generating belt 1. Furthermore, the process for creating the U-shaped hole 125 in the housing 12 is simple, facilitating the fabrication of the lift tab 123. The U-shaped hole 125 also accommodates the grounding port 3, avoiding increasing the thickness of the heat-generating belt 1 during installation.

[0031] Please refer to Figure 1 and Figure 2 A connection hole 122 is provided on the housing 12. A wire 4 is provided in the connection hole 122 to contact the heating layer 11, and the wire 4 connects the heating belt 1 to the circuit.

[0032] Preferably, the housing 12 is provided with a convex bump 121. A connection hole 122 is provided in the convex bump 121. An insulating block 5 is provided within the convex bump 121 to enclose the wire 4. The insulating block 5 is fixed between the convex bump 121 and the heating layer 11. The fixing of the insulating block 5 relies on the structure of the heating belt 1 itself, and no additional fixing parts are required.

[0033] The specific assembly process of this embodiment is as follows:

[0034] Insert the lift tab 123 between the second flange 34 and the insert segment 33, press the second flange 34, and clamp the lift tab 123 between the second flange 34 and the insert segment 33. Insert the ground wire 2 between the first flange 32 and the connecting segment 31, press the first flange 32, and clamp the ground wire 2 between the first flange 32 and the connecting end to achieve grounding of the heat-generating belt 1.

[0035] Example 2

[0036] Figure 3 The figure shows a schematic diagram of the three-dimensional structure of the liquid heater in the second embodiment of the present invention. Figure 3 Based on the first embodiment, the second embodiment discloses a liquid heater, comprising a container 7 and a heat-generating belt 1. The heat-generating belt 1 is sleeved onto the container 7. A raised flange 71 is provided circumferentially on the container 7. The flange 71 abuts against the lower portion of the heat-generating belt 1. When the heat-generating belt 1 is sleeved onto the container 7, the flange 71 quickly positions and supports the heat-generating belt 1. The assembly between the container 7 and the heat-generating belt 1 is simplified, improving assembly efficiency of the liquid heater.

[0037] Preferably, the two short sides of the shell 12 are folded toward the same side to form a connecting portion 124. The connecting portion 124 is connected and fixed by a fastener 6, and tightening the fastener 6 drives the heat-generating belt 1 to expand or contract. The fastener 6 passes through the two connecting portions 124 at the same time, connecting the two ends of the heat-generating belt 1. The fastener 6 can be a bolt, a stud nut, a screw or a pin. When the heat-generating belt 1 is mounted on the container 7, first loosen the fastener 6, move the heat-generating belt 1 to the mounting position of the container 7, and the flange 71 rests on the lower part of the heat-generating belt 1. Then tighten the fastener 6, and the heat-generating belt 1 shrinks and is tightened on the container 7, completing the connection between the heat-generating belt 1 and the container 7.

[0038] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention.
