The tension force that compression spring under the state of contracting produces applies downward pressure to described sealing column, makes described sealing column
It is pressed on described steam vent.
Described handle is internally provided with temperature detect switch (TDS) and exhaust passage, and one end, described exhaust passage is opened with described temperature control
Pass communicates, and the other end is connected with the port of export of described first row air drain.
Further, the port of export of described first row air drain is provided with sealing shroud, prevents steam leakage.
When the present invention works, described heating board heats the water in described water gallbladder, and the heat of water passes through described inner bag table
After face is dispersed into described occluded air layer, owing to described vacuum layer encloses described occluded air layer, thus completely cut off
Heat scatters and disappears.
When hot water seethes with excitement, creating substantial amounts of steam in described water gallbladder, the pressure in described water gallbladder increases,
When the pressure that the pressure acting on described sealing column acts in sealing column more than described compression spring, described close
Envelope post backed down by steam, steam is entered in described air discharge duct by described steam vent, due to described air discharge duct with
The exhaust passage of described handle communicates, and steam enters into inside described handle by described air discharge duct, with described
Temperature detect switch (TDS) in handle contacts, and after described temperature detect switch (TDS) is sensed by heat, disconnects with power supply, electricity
Hot-water bottle stops heating.
