As shown in Figures 3, 4, 5~1 2, the electric hot beverage beverage container of the present invention comprises a kettle body 1, a container 3, a funnel 4, an upper filter layer 5, a lower filter layer 6, and a bottom surface 7 of the container. Outer torus 8, electric heater 9, gap 10, cover 11, pipe 12, collar 13, isolation chamber 14, facing 15, cap 16, annular groove 17, sealing ring 18, Clamping member 19, dowel 20, body 21, connector electrodes 22, 23, electrical connection terminals 24, 25, first movable contact piece 26, first certain contact piece 27, temperature-sensitive bimetal 28, first top Rod 29, tilt arm 30, tilt positioning member 31, spring member 32, reset lever 33, metal plate 34, metal spring 35, second movable contact 36, second fixed contact 37, low temperature melting point rivet 38, Two jacks 39, a base 40, a temperature-controlled electrical connector plug 41, an electrical connector receptacle 42, and an electric boiled beverage container 43.

The electric boiling beverage container therein has been described above, and will not be described herein.

The temperature-controlled electrical connector plug 41 includes a plug-in electrode 22, 23 and an electrical connection terminal 24, 25 disposed on the body 21, and is disposed between a set of the connector electrode 22 and the electrical connection terminal 24. The first movable contact piece 26 and the first fixed contact piece 27 are provided with a spring pressure contact, and the body 21 is provided with a temperature-sensitive bimetal 28, and the first movable contact piece 26 and the temperature-sensitive bimetal piece 28 are provided with a first A ram 21 is disposed on the body 21, and a tilting arm 30 is disposed between the body 21 and the rocker arm 30. The body 21 is provided with a spring biasing arm. The elastic member 32 of the upper end 30 of the inner end 30, the elastic member 32 can be biased and lifted by the spring arm 30, and the lower end 30 〃 of the inner end of the rocker arm 30 can touch the first movable contact piece 26 and the first fixed contact piece 27 Separating, the body 21 is provided with an external force, which can move toward the elastic member 32, and touches the reset rod 33 elastically deformed by the elastic member 32 away from the inner end 30' of the arm 30, and only then Pressing the rocker arm 30, the lower end 30 内 of the inner end of the rocker arm 30 is accordingly tilted and separated from the first movable contact piece 26, The first movable contact piece 26 is in elastic contact with the first fixed contact piece 27. The reset lever 33 is disposed in the cavity 21' of the body 21 into which the connector socket 42 can be supplied.

When the reset lever is not pushed by the external force, the first movable contact piece and the first fixed contact piece are always kept separated. Even if the tilting arm is pressed, once the hand is released, the tilting arm will be under the elastic force of the elastic member. Back to back. When the reset lever is pushed by the external force, only the arm is pressed again, and the inner end of the arm is tilted and separated from the first movable contact, and the first movable contact is The first contact piece is pressed and pressed. At this time, the temperature-sensitive bimetal is changed by heat, and the tilting action can make the first movable contact piece and the first fixed contact piece open and close, which is a temperature control state, and the tilting arm at this time is in the open state of the switch. When the tilt arm is pressed in the opposite direction, the tilt arm is in the closed state of the switch.

Since the upward elastic force of the elastic member is greater than the elastic force of the tilting positioning elastic member, the outer end portion of the tilting arm is still lifted after being pressed, and the inner movable end of the tilting arm touches the first movable contact piece to make the first Separate the contacts. The electrical connection between the electrical connection terminal and the connector electrode is in an open state to avoid arcing on the connector electrode during the insertion process. When the reset lever is pushed up by the applied force, the spring is tilted upward and separated from the inner end of the arm.

When the inner end of the tilting arm is in the downwardly tilted state, the elastic force of the tilting positioning elastic member is sufficient to overcome the elastic force of the first movable contact piece, and the first movable contact piece is kept separated from the first fixed contact piece. The arm is equivalent to a manual switch, which can be turned on and off by turning up and down. Once the applied force on the reset lever disappears, the state of the tilt arm is now in the power When the connection end and the connection electrode are in the off state, they will eventually become disconnected. When the temperature sensitive bimetal will sense the dry burning temperature and warp, the first plunger is driven to separate the first movable contact from the first fixed contact, and the power path is cut off. When the temperature sensitive bimetal is sensed and then reset after the temperature is lowered, the first ram loses the warping pressure of the temperature sensitive bimetal, so that the first moving contact and the first fixed contact are brought into contact again to turn on the power. , so cycle and reciprocate, to achieve dry burning temperature control. This intermittent energization keeps the electric heater at a relatively constant temperature. When the tilting arm is pressed, the first movable contact piece is kept separated from the first fixed contact piece, and the manual switch is disconnected. At this time, regardless of whether the temperature sensitive bimetal is thermally warped, the first moving contact piece and the first fixed piece are fixed. The contacts remain separated for manual shutdown.

The plug electrodes 22, 23 are annular structures, and the electrical connection end 24 and the first fixed contact piece 27 are made of a metal piece in an S-shaped structure. The elastic member 32 is an elastic L-shaped steel wire, and the bent portion is fixed to the body 21. The swaying positioning member 31 is a metal elastic piece that is loosely held between the body 21 and the slanting arm 30 so that the slanting arm 30 can be held in a state of being lifted and pressed.

When the electric boiled beverage container 43 is separated from the base 40, since the upward elastic force of the elastic member 32 is greater than the elastic force of the tilting positioning elastic 31, the outer end portion of the tilting arm 30 is still lifted after being pressed, and the tilting arm 30 is at this time. The lower end of the inner end 30" touches the first movable contact piece 26 to be separated from the first fixed contact piece 27. That is, the electric heating beverage container 43 is connected to the electrical connection end 24 before being placed on the base 40. The interposing electrodes 22 are in an open state to avoid arcing on the plug electrodes 22, 23 during the insertion process.

After the electric boiling beverage container 3 is placed on the base 40, since the temperature-controlled electrical connector plug 41 and the electrical connector socket 42 are plugged together, the reset lever 33 is electrically connected under the action of the downward gravity of the electric cooking beverage container 43. The socket 42 is lifted up, at which time the spring 32 is lifted upwardly and separated from the upper end 30' of the arm 30. When the inner end of the rocker arm 30 is in the upwardly tilted state, the first movable contact piece 26 is in contact with the first fixed contact piece 27. When the inner end of the rocker arm 30 is in the downwardly tilted state, the elastic force of the warp positioning elastic member 31 is sufficient to overcome the elastic force of the first movable contact piece 26, and the first movable contact piece 26 and the first fixed contact piece are provided. 27 remains separated. Therefore, after the electric boiling beverage container 43 is placed on the base 40, the tilting arm 30 is equivalent to a switch, and can be turned on and off by turning up and down. When the electric boiled beverage container 43 is separated from the base 40, the state of the arm 30 is now in an open state in which the electric heater 9 and the plug electrode 22 are turned on and off. In use, the electric boiling beverage container 43 is first placed on the base 40, and then the outer end of the lifting arm 30 is pressed, and the electric heater 9 is energized to generate heat. When the water in the inner container 3 is dried, the bottom surface thereof is The temperature will continue to rise. At this time, the temperature sensing bimetal 28 will sense the dry burning temperature and warp, and drive the first jack 29 to separate the first moving contact piece 26 from the first fixed contact piece 27, and cut off the power supply. So that the kettle body is no longer heated and keeps the outer surface temperature low. When the temperature-sensitive bimetal 28 senses that the temperature of the bottom surface of the inner container 3 is lowered and then resets, the first movable contact piece 26 is brought into contact with the first fixed contact piece 27 again to electrically heat the electric heater 9, so that the cycle is repeated to achieve dry burning. Temperature control. This intermittent heating only maintains the electric heater 9 at a relatively constant temperature, and can heat the beverage in the kettle body 1, such as coffee, to achieve the purpose of fragrant and delicious, and keep the outer surface of the kettle body 1 in one. Relatively constant temperature state. When the beverage is brewed again next time, the user's holding operation is facilitated due to the bottom surface temperature of the kettle body.

The body 21 is provided with a metal plate 34. The metal plate 34 is provided with a metal elastic piece 35. The raised end of the metal elastic piece 35 is fixed on the metal plate 34 by the low temperature melting point rivet 38, and the other set of the connection electrode 23 and A second movable contact 36 and a second fixed contact 37 are provided between the electrical connection ends 25, and a second plunger 39 is disposed between the second movable contact 36 and the raised end of the metal dome 35. When the low temperature melting point rivet 38 is melted by heat to cause the metal dome 35 to lift, the second plunger 39 can be driven to lift the second movable contact 36 to separate from the second fixed contact piece 37. The electrical connection 25 and the second stator 37 are also made of a metal sheet in an S-like configuration.

When the dry temperature control fails, the temperature of the bottom surface of the inner container 3 will continue to rise until the low temperature melting point rivet 38 is melted, the metal dome 35 bounces, and the second plunger 39 is driven to lift the second movable contact 36. The second fixed contact piece 37 is separated, and the power supply to the electric heater 9 is completely cut off, so that the over temperature control is realized, so that the surface temperature of the kettle body does not rise due to the failure of the dry temperature control.

In summary, the present invention heats the bottom surface 7 of the main heat conduction container by heating the electric heater 9 on the outer ring surface 8 to heat the bottom surface 7 of the container, and uses the gap 10 to heat the other surface of the electric heater 9. The generated heat energy is transmitted to the bottom surface 2 of the kettle body through the air, and the bottom surface 2 of the kettle body is preheated, thereby realizing the heating of the inner container 3 and the preheating of the bottom surface 2 of the kettle body by using an electric heater 9, which is energy-saving and structurally simple. The temperature on the outer surface of the electric boiling beverage container is reduced, which is convenient for the user to hold and open. At the same time, through the improvement of the structure of the cover, the water vapor is prevented from being directly ejected from the port of the kettle body, so that the temperature of the cover is also reduced and the use is convenient.
