[0027] Figure 1 Shown is a schematic diagram of the explosion structure of the liquid heater of the present invention. Figure 2 The figure shows a cross-sectional structural diagram of the liquid heater of the present invention with the container hidden. Figure 3 It shows a partial enlarged view of the liquid heater of the present invention at point A. Please refer to Figure 1 、 Figure 2 and Figure 3 , liquid heater, the liquid heater includes a container 1, a heating coil 2 and a thermostat 4. The heating coil 2 is mounted on the container 1 for temperature monitoring. The thermostat 4 is arranged on the heating coil 2, and a flange 41 is provided circumferentially on the thermostat 4. Among them, the heating coil 2 includes a heating layer 21 and an outer shell 22. The heating layer 21 is arranged in the outer shell 22. A first convex bump 223 is formed on the outer shell 22, and a first connecting hole 224 is provided on the first convex bump 223. The thermostat 4 contacts the heating layer 21 along the first connecting hole 224, so that the thermostat 4 can sense the temperature change of the heating coil 2 more quickly, and then quickly adjust the working state of the heating coil 2, thereby improving the response speed of the entire liquid heater to the temperature. At the same time, the thermostat 4 can directly contact the heating layer 21, so that the thermostat 4 can obtain more real temperature control data, reduce the stabilization delay caused by air flow or other factors, and improve the accuracy of temperature control. The flange 41 is set between the first convex bump 223 and the heating layer 21 and is limited. That is, the thermostat 4 is fixed to the heating coil 2 by the structure of the heating coil 2 and the thermostat 4 itself, without the need for fastening structures such as screws, thereby avoiding the need for too many parts and slowing down assembly. The first protrusion 223 and the first connecting hole 224 not only fix the thermostat 4, but also quickly locate the position between the thermostat 4 and the heating coil 2, further simplifying the assembly of the liquid heater.

[0028] Figure 4 It shows a partial enlarged view of the liquid heater of the present invention at B. Please refer to Figure 2 and Figure 4 A second connection hole 226 is provided on the outer shell 22. A wire 5 is provided in the second connection hole 226 to contact the heating layer 21. The wire 5 connects the heating layer 21 to the circuit. The heating layer 21 includes a heating core 211 and an insulating layer 212. The insulating layer 212 wraps the heating core 211 to prevent a short circuit between the heating core 211 and other conductive bodies. A hole is provided in the insulating layer 212 at the position of the second connection hole 226. The wire 5 can directly contact the heating core 211 along the hole.

[0029] Preferably, an insulating block 6 is disposed within the second connection hole 226. The insulating block 6 encases the wire 5 extending into the heating coil 2. The insulating block 6 effectively isolates the current, preventing it from flowing through the wire 5, the first protective shell 221, and the second protective shell 222, thereby protecting the safety of the liquid heater and the user.

[0030] More preferably, a second convex hump 225 is provided on the heating coil 2, and a second connecting hole 226 is provided on the second convex hump 225. An extension portion 61 is provided circumferentially on the insulating block 6, and the extension portion 61 is provided between the second convex hump 225 and the heating layer 21 and is limited. The insulating block 6 is fixed to the heating coil 2 by the structure of the heating coil 2 itself, without the need for fastening structures such as screws, thereby avoiding too many parts and components that reduce the assembly speed. While the second convex hump 225 and the second connecting hole 226 fix the insulating block 6, they also quickly locate the position between the insulating block 6 and the heating coil 2, further simplifying the assembly work of the liquid heater.

[0031] Please refer to Figure 1 、 Figure 2 and Figure 3 The outer shell 22 includes a first protective shell 221 and a second protective shell 222. The two long sides of the first protective shell 221 are folded over to hold the second protective shell 222. Before manufacturing the first protective shell 221, the first protective shell 221 is folded over. Subsequently, the second protective shell 222 is directly inserted into the slot formed by the folded first protective shell 221 to connect the first protective shell 221 and the second protective shell 222.

[0032] Preferably, the two short sides of the second protective shell 222 are folded toward the side away from the container 1 to form a connecting portion 227. The connecting portion 227 facilitates the connection and fixation of the two ends of the heating coil 2. At the same time, the connecting portion 227 can abut the two short sides of the first protective shell 221, restricting the second protective shell 222 from sliding along the first protective shell 221, thereby improving the stability of the connection between the first protective shell 221 and the second protective shell 222.

[0033] More preferably, the two connection parts 227 are connected and fixed by a fastener 3, and the fastener 3 can be a bolt, a screw, etc.

[0034] Furthermore, container 1 is preferably provided with a circumferential flange 11, which contacts the lower portion of heating coil 2 to support the heating coil 2. When the heating coil 2 is placed on container 1, flange 11 quickly positions and supports it. This simplifies assembly between container 1 and heating coil 2, improving assembly efficiency of the liquid heater.

[0035] The specific assembly process of this utility model is as follows:

[0036] Wrap the heating core 211 with the insulating layer 212, let the thermostat 4 pass through the first connecting hole 224, and the inner wall of the first bulge 223 contacts the flange 41. Let the insulating block 6 pass through the second connecting hole 226, and the inner wall of the second bulge 225 contacts the extension 61. Then insert the heating layer 21 and the second protective 222 into the first protective shell 221, and the heating layer 21 is between the first protective shell 221 and the second protective shell 222. At this time, the heating layer 21 is arranged between the first protective shell 221 and the second protective shell 222, the flange 41 is arranged between the first bulge 223 and the heating layer 21, and the extension 61 is arranged between the second bulge 225 and the heating layer 21. Bend the two short sides of the second protective shell 222 against the two short sides of the first protective shell 221. Complete the assembly of the heating coil 2 and the thermostat 4.

[0037] Then, the heating coil 2 is placed on the container 1, and the flange 11 supports the lower part of the heating coil 2. The fastener 3 connects the two connecting parts 227 to fix the heating coil 2 on the container 1, completing the assembly of the liquid heater.
