Each end plate is connected to the installation shell by screws. A temperature control switch for protecting the heating tube is arranged on the installation shell, a water passing interface is arranged outside the metal end cover, and a temperature detection element is connected to at least one water passing interface.

[0005] Further, the installation shell includes a protective shell, and installation short columns are evenly arranged on the protective shell, and blind holes are arranged on the installation short columns.

[0006] Further, the heating cavity between the central flow guide column and the heating tube is formed into a spiral flow channel by spiral flow disturbing sheets.

[0007] Further, the heating tube includes a heating base tube, a heating circuit is arranged on the outer side of the heating base tube, a conductive wiring terminal is welded on the heating tube, and is connected to an external wire through the conductive wiring terminal, so as to supply power to the conductive wiring terminal and the heating circuit through an external power supply, and the heating base tube can be used for support, and the liquid can be heated by the heating circuit, making the heating faster and the heating effect better.

[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows: the spiral spoiler can form an S-shaped flow channel inside the heating cavity, thereby making the heating effect better; the conductive connection terminal is connected to an external wire, so as to supply power to the conductive connection post and the heating thick film through the conductive connection terminal; the heating base tube can provide support; and the heating circuit can heat the liquid, making the heating faster and the heating effect better. The hardware end cap heater has a simple structure and is easy to operate. It not only makes the heating effect better, effectively ensures that the heated liquid is more uniform, but also heats faster, is hygienic and safe, and has no peculiar smell.
