The specific embodiment

Referring to Fig. 1-3, the temperature controller of the utility model cordless electrothermal kettle and connector are made up of control section (25) and power supply coupling part (26) two parts.Control section is one one head breadth, and one narrow, and there is the working of plastics of a circular open centre.Its narrow end is equipped with a quick assembly of vapour and a bipolar lever assembly (24), and the quick assembly of vapour is made up of a vapour thermal excitation (20) and a shell fragment (21), and bipolar lever assembly (24) is installed on the working of plastics, joins with the porcelain bar (15) that stretches out from the L utmost point and the N utmost point.L1 and N1 are two pairs of contacts, and L1 is made up of the movable contact L1R on fixed contact L1T on the conducting strip (19) and the conducting strip (12), and N1 is made up of the movable contact N1R on fixed contact N1T on the conducting strip (17) and the conducting strip (12).Vapor (steam) temperature raises in container, and the quick assembly of vapour discharges elastic force, promotes bipolar lever assembly (24), and bipolar lever assembly (24) promotes the L utmost point and N utmost point contact simultaneously, cuts off the electricity supply.When manually pressing lever (24), system resumes work again.

Circular open place in the middle of working of plastics has one by the fastening dome (11) of Luo silk (6), four outstanding tablets that boss and heat-generating pipe are steadily contacted are arranged on the dome (11), dome has a boss on (11), thermally-responsive controls (3) and thermal cut-off (4) are housed in the boss, have an aluminium lid (1) to seal boss interior thermally-responsive controls (3) and thermal cut-off (4) admittedly on the boss.When internal tank did not have liquid, the heat generating components temperature raise, and passed to thermally-responsive controls (3) from the aluminium lid (1) of being close to the surface, and thermally-responsive controls (3) distortion back promotes a porcelain bar (8), pushes the L2 contact open, cuts off the electricity supply.Contact L2 is made up of the fixed contact L2T on movable contact L2R on the conducting strip (19) and the conducting strip (23).After temperature descended, thermally-responsive controls (3) resetted, and the L utmost point is connected.When overtemperature is cut off the electricity supply and reset and protection when losing efficacy automatically; heat-generating pipe (34) temperature constantly raises; the fusing of overheat fusion body; between pad (5) and (9); withstand porcelain bar (7) retracting spring of compression spring (10); cut off the N2 contact, the N2 contact is made up of the fixed contact N2T on movable contact N2R on the conducting strip (14) and the conducting strip (17), thereby cuts off the electricity supply.

The wide end of working of plastics is the inserted sheet that joins with the power supply coupling part, the metal electrode L utmost point (23) that is separated by working of plastics is arranged on the inserted sheet, the N utmost point (22) and ground wire (18), ground wire (18) is positioned in the middle of the L utmost point (23) and the N utmost point (22), there is arc plastics distance piece (35) both sides of inserted sheet, play the guiding role when joining with the coupling part.

Power supply coupling part (26) is a socket, and the protection against electric shock lid is housed on the socket.This protection against electric shock lid is a slide block (28), is installed on the slide unit (27) that is fixed on the housing, and a steel pole (29) is arranged on the slide block (28), can promote slide block (28) and move.Electrode slice (31) is housed, (32) and (33) in the socket.Slide block when temperature controller inserts (28) is open, and slide block when extracting (28) closes under the effect of steel pole (29), plays the effect of getting an electric shock of preventing.

Referring to Fig. 4, the temperature controller of the utility model cordless electrothermal kettle and the connector dome (11) in the middle of working of plastics locates to be fixed with heat-generating pipe (34), and temperature controller and connector are vertically connected on the kettle bottom along the electric kettle housing direction.
