Further, the heating plate is an alumina ceramic heating plate. The alumina ceramic heating plate is fast in temperature rise and uniform in heating.

Further, the thickness of the first silica gel pad is smaller than that of the second silica gel pad. The first silica gel pad is thinner and can better and more evenly pass the heat to the heating base. And the second silica gel pad is thicker, because can wear and tear the second silica gel pad during dismouting clamp plate, thick silica gel pad can bear more wearing and tearing volume.

Further, the heating base is brass. The brass has good heat conduction capability, and can quickly heat the dispensing valve.

Further, the heating port is of a circular ring-shaped structure and is matched with the dispensing valve. The contact connection more readily transfers heat from the heating port to the dispensing valve.

Compared with the prior art, the beneficial effects of the utility model are that: the heating piece transfers heat to the silica gel pad, the silica gel can be more uniform for heating the base, the heating base heats the dispensing valve, the thermocouple on the heating base and the controller are matched to control the temperature of the heating base, and the dispensing valve is kept in the optimal dispensing state at all times. Improve the operating efficiency of the dispensing valve, the device has simple structure, convenient maintenance and economical and practical properties.
