The heating substrate 220 is abutted and matched with the water passing plate 210 and blocks the first continuous water channel 211 and the second continuous water channel 212 to form two closed water channels which are independently arranged, two heating zones which are in one-to-one correspondence with the first continuous water channel 211 and the second continuous water channel 212 are arranged on one surface, back to the water passing plate 210, of the heating substrate 220 at intervals, and each heating zone is respectively provided with a heating body 221 which is electrically connected with the electric control plate 130 and generates heat when power is connected and a temperature sensor 222 which is electrically connected with the electric control plate 130 and is used for detecting water temperature. It should be noted that, in this embodiment, the heating area on the heating substrate 220 is not directly contacted with water, specifically, after the heating body 221 generates heat under the control of the electric control board 130, heat radiation is generated to the heating substrate 220, so that the surface of the heating substrate 220 facing away from the heating area is heated, and further heat radiation is generated to the water body contacted with the heating substrate 220, and the heat on the heating substrate 220 is taken away by this part of water, so that while the water body is heated, the problem of overheating of the heating area is avoided, and the safety of the heater in use is improved.

Further, in one embodiment, a sealing structure 215 is disposed on the water passing plate 210 between the first continuous water passage 211 and the second continuous water passage 212.

Referring to fig. 6, the heating body 221 shown in fig. 6 is a resistance wire wound on the surface of the heating base 220, and when the resistance wire is wound on the heating base 220, after the resistance wire is powered on, when current passes through the resistance wire, the current does work to consume electric energy, so as to generate heat, and generate heat radiation to the heating base 220, so as to transfer the heat to water in contact with the heating base 220, thereby heating the water body. It should be noted that, in this embodiment, no matter a manner of coating thick film paste or graphene or a manner of winding a resistance wire is adopted, the heating body 221 is not disposed at a position between two sub-heaters, so that, in the working process of the segment control heater 200, a position on the heating substrate 220 where paste is not coated or a portion on which a resistance wire is wound does not generate heat, that is, the temperature change of the transition portion between the two sub-heaters is small, thereby reducing the heat transfer amount between the two heating regions, and improving the reliability of the segment heating operation of the segment control heater 200 of this embodiment.

In one embodiment, the heating substrate 220 is an integrally formed structure or includes two sub-substrates detachably connected, and when the heating substrate 220 includes two sub-substrates detachably connected, each sub-substrate is correspondingly provided with a heating zone, a heating body 221 and a temperature sensor 222; when the water passing plate 210 includes two detachably connected components, each component is correspondingly provided with a continuous water channel and a water inlet and a water outlet communicating with the continuous water channel, for example, two ends of the first continuous water channel 211 are respectively provided with a first water inlet 211a and a first water outlet 211b, and two ends of the second continuous water channel 212 are respectively provided with a second water inlet 212a and a second water outlet 212 b.

It is understood that the heating substrate 220 and the water passing plate 210 may be integrated, one of them may be integrated, the other may be disassembled, or both may be disassembled. When the heating base body 220 and the water passing plate 210 are both detachable structures, two sub-heaters which are independent of each other and can be detached independently are actually formed, so that when any one part on the sectional control heater 200 is damaged, the damaged part can be maintained and replaced independently, and the use cost of the sectional control heater 200 is reduced.
