| 摘要 |
The invention relates to an electrically functioning thermos flask 1, and more particularly one of the type comprising a pump 61, similar to a diaphragm, mounted in the flask and comprising a motor 62 coupled by an eccentric link to a flexible diaphragm formed from a rubberized material and tightly fitted over an opening of a casing 44 comprising a air outlet in its bottom; a switch 10 of the key type is disposed at the water outlet of the thermos flask 1 and, once this switch 10 is pushed by a cup A or by a finger, the shaft of the motor 62 is driven in rotation producing a vibratory motion of the diaphragm such that the air in the casing is driven via the air outlet into the inside of the flask and that the water is discharged from the latter due to the increase in air pressure inside the flask 1. <IMAGE>
