[0006] The above scheme is adopted, by setting an adjustment mechanism to cooperate with the piston moving plate, the air inlet and the air outlet. When the adjustment mechanism drives the piston moving plate to move forward, the high-temperature steam of the boiled water in the electric kettle is extracted into the cavity. When the adjustment mechanism drives the piston moving plate to move backward, the high-temperature steam is discharged through the exhaust pipe, thereby preventing the high temperature from spraying straight up when the kettle lid is opened, effectively avoiding burns. The gas is discharged from the side, which has a good protective effect. By setting a filter for use in combination, the filter can prevent foreign matter from being extracted into the cavity and causing blockage, and the filter is easy to disassemble and clean. The sealing cover can be opened when exhausting and closed after exhausting, to prevent debris from entering the exhaust pipe and causing blockage of the exhaust pipe, thereby improving functional diversity.

[0011] As a preferred embodiment, a sealing ring is attached to the outer surface of the piston moving plate, and the outer surface of the sealing ring is in sealing contact with the inner wall of the cavity.
[0012] By adopting the above solution and using the sealing ring in combination, it is possible to prevent the cavities on the front and rear sides of the piston moving plate from being connected, thereby achieving a good sealing effect.
[0013] As a preferred embodiment, several grooves are opened on the side of the mounting plate, and a sliding rod is slidably installed at the position of the mounting plate opposite to the groove. An operating plate is fixed to one end of the sliding rod, and the other end of the sliding rod is fixedly connected to the card rod. The outer sleeve of the sliding rod is provided with a spring whose two ends are respectively connected to the inner wall of the groove and the card rod.
[0014] By adopting the above solution, the elastic action of the spring is used to drive the slide bar to drive the clamping bar to move, and then the clamping bar is clamped into the clamping slot to realize the unlocking and locking operations of the filter screen.
[0015] As a preferred embodiment, two fixed blocks are fixedly installed on the outer surface of the exhaust pipe, a fixing rod is fixed between the two fixed blocks, a torsion spring is sleeved on the outer surface of the fixing rod, a circular hole is opened on the sealing cover, the torsion spring is located inside the circular hole, and the two ends of the torsion spring are respectively fixedly connected to the inner wall of the circular hole on the sealing cover and the outer surface of the fixing rod.

After the exhaust is completed, the sealing cover is reset under the action of the torsion spring, thereby improving the convenience of operation.
[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] The high-temperature steam ejection prevention mechanism of the electric kettle when the lid is opened is used by arranging an adjustment mechanism in conjunction with a piston movable plate, an air inlet and an air outlet. When the adjustment mechanism drives the piston movable plate to move forward, the high-temperature steam from boiling water in the electric kettle is extracted into the cavity. When the adjustment mechanism drives the piston movable plate to move backward, the high-temperature steam is discharged through the exhaust pipe, thereby preventing the high-temperature steam from ejecting straight upward when the kettle lid is opened, effectively preventing burns. The gas is discharged from the side, which has a good protective effect.
[0019] The lid-opening anti-high-temperature steam ejection mechanism of the electric kettle is used in conjunction with a filter screen, which can prevent foreign matter from being drawn into the cavity and causing blockage. The filter screen is easy to disassemble and clean, and the sealing cover can be opened when exhausting and closed after exhausting to prevent debris from entering the exhaust pipe and causing blockage of the exhaust pipe, thereby improving functional diversity.

[0028] The adjusting mechanism includes two rotating shafts 2 rotatably mounted on the front and rear sides of the inner wall of the cavity, a lead screw 3 mounted between the two rotating shafts 2, a worm gear 6 fixed to the end of one of the rotating shafts 2, a worm 5 rotatably mounted on the kettle cover 1 with the bottom end located inside the cavity, and a knob mounted on the top of the worm 5. The worm 5 and the worm gear 6 are used in conjunction with each other, and the piston moving plate 4 is threadedly mounted on the outer surface of the lead screw 3. The meshing action of the worm 5 and the worm gear 6 makes the rotating shaft 2 drive the lead screw 3 to rotate, thereby driving the piston moving plate 4 to move back and forth, thereby drawing high-temperature steam into the cavity.
[0029] Guide rods 7 are provided at the four corners of the piston moving plate 4. The piston moving plate 4 is slidably mounted on the outer surface of the guide rods 7, and the guide rods 7 are fixedly mounted on the inner wall of the cavity. The setting of the guide rods 7 can support and guide the movement of the piston moving plate 4, so that the movement stability of the piston moving plate 4 is better and it is not easy to tilt and shake.
[0030] A sealing ring 20 is pasted on the outer surface of the piston moving plate 4, and the outer surface of the sealing ring 20 is sealed against the inner wall of the cavity. The setting and use of the sealing ring 20 can prevent the cavities on the front and rear sides of the piston moving plate 4 from being connected, thereby achieving a good sealing effect.
[0031] Several grooves are provided on the side of the mounting plate 9, and a slide rod 10 is slidably installed at the position opposite to the groove on the mounting plate 9. An operating plate 12 is fixed to one end of the slide rod 10, and the other end of the slide rod 10 is fixedly connected to the card rod 11. The outer sleeve of the slide rod 10 is provided with a spring 13 whose two ends are respectively connected to the inner wall of the groove and the card rod 11. The elastic action of the spring 13 drives the slide rod 10 to drive the card rod 11 to move, and then the card rod 11 is snapped into the card slot to realize the unlocking and locking operations of the filter 8.
[0032] Two fixing blocks 16 are fixedly installed on the outer surface of the exhaust pipe 14, and a fixing rod 17 is fixed between the two fixing blocks 16.

The knob drives the worm 5 to rotate, and the worm 5 and the worm wheel 6 cooperate to drive the rotating shaft 2 to drive the screw 3 to rotate, thereby driving the piston moving plate 4 to move forward. When the piston moving plate 4 moves forward, it will draw high-temperature steam into the cavity through the air inlet, and then reverse the knob to drive the piston moving plate 4 to move backward. At this time, the high-temperature steam in the cavity will be discharged through the exhaust pipe 14. This reciprocating process will discharge the high-temperature steam just boiled from the side. Out, and then open the kettle lid 1, which can effectively avoid the possibility of scalding caused by the straight discharge of high-temperature steam. At the same time, the exhaust pipe 14 will drive the sealing plate to rotate and open when exhausting, and the torsion spring 19 will deform. After the exhaust is completed, the torsion spring 19 elastically drives the sealing cover 18 to reset. At the same time, the filter screen 8 is operated to filter when the air is taken in to prevent debris from entering the cavity. The filter screen 8 can be removed for cleaning later. When disassembling, pull the operating panel 12 to drive the slide bar 10 to move, and the slide bar 10 drives the card rod 11 to disengage the card slot, and remove the filter screen 8 for cleaning.
