[0029] By providing a heating cavity 9 in the heating pump 100 and arranging it side by side with the main body 2, the structure of the heating pump 100 can be simplified, and the heating cavity 9 is easy to disassemble and assemble, and is convenient to replace, which extends the service life of the heating pump 100, greatly saves labor and costs, and increases the layout space of the heating component 5, thereby improving the heating efficiency.

[0030] Furthermore, the straight line determined by the length direction of the heating cavity 9 is parallel to the axis of the rotating shaft 11 of the motor 1.

This can prevent the conductive connector 54 from contacting the fluid passing through the flow channel 6 and causing a short circuit, and can also prevent the fluid from entering the first cavity 15 and contacting the circuit board assembly 10 and causing a short circuit.

[0043] Specifically, the isolation sleeve 14 includes an inner annular wall 142, an outer annular wall 143 and a connecting wall 144 connecting the two.

The first through hole 141 and the liquid hole 1433 are staggered.

[0046] Example 2

[0047] The difference between this embodiment and the first embodiment is only that the setting position of the heating component 5 and the setting position of the conductive connecting member 54 are different.
