The leakproof structure is characterized in that the lower end of the transmission shaft is provided with a linkage cross bar assembly, the linkage cross bar assembly comprises a linkage cross bar, a sealing cover, a sealing cover and a torsion spring, one end of the linkage cross bar is rotatably connected with a fixed lever below a middle partition plate, the other end of the linkage cross bar is provided with the sealing cover which covers the water outlet upwards, the sealing cover is provided with a kettle mouth sealing ring, the fixed lever is externally sheathed with the torsion spring, and one end of the torsion spring supports against the bottom surface of the sealing cover. The button is pressed down for a certain distance to drive the transmission shaft to goes down, the linkage cross bar is pushed to rotate around the fixed lever, the sealing cover leaves the water outlet, the transmission shaft is uplifted under the action of the return spring, the sealing cover tightly covers the water outlet, the phenomenon that sealing of the sealing cover is not tight owning to offside of the transmission shaft can be avoided, and the transmission shaft is uplifted so that a lower disc limiting block at the lower end of the transmission shaft seals a connecting hole, thus water cannot leak from a water outlet end even if a kettle body falls sidewards.
Description
Technical field
The present invention relates to a kind of sealing mechanism, particularly a kind of hermetically-sealed construction of electric kettle discharging mouth.
Background technology
Electric kettle is a kind of utensil to boil water fast, is all generally to use in hotel, hotel, but, along with growth in the living standard, increasing average family is also brought into use electric kettle.The most of pot lid of electric kettle in the market is all packing less, if in use careless side is fallen, the water in kettle will topple over out, causes accident.Electric kettle utilizes the hermetically-sealed construction of combining closely between pot lid and kettle body, delivery port and the hermetically-sealed construction at steam chamber place to reach whole anti-side leakage usually.
CN201379426Y has proposed the safety sealing device of electric kettle, the hermetically-sealed construction of its delivery port comprises spout valve door, connecting rod, lever and water outlet button, by pressing the water outlet button promotion connecting rod that is positioned at the handle inboard, advance, make lever one end climb along the domatic of connecting rod, cause the lever other end to press down and open the spout valve door.The connecting rod of this valve-opening mechanism and lever, connecting rod coordinate with docking between the water outlet button must be accurately, and when coordinating when not in place, whole valve-opening mechanism will lose effectiveness, and the spout valve door is not just opened.
JP2009-172109A discloses a kind of hermetically-sealed construction of electric kettle discharging mouth, it connects a trace under the top cover button, by the sealing of the sealing ring on trace intermediate plate delivery port, the connecting rod action should play upper and lower connection function, plays again the sealed against leakage effect, but pressing when not in place, the top cover button can sink and the pot lid end face, the delivery port of not opening, and press when excessive, connecting rod can be backed down, and causes sealing not in place and does not have the leakproof effect.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of hermetically-sealed construction of electric kettle discharging mouth of simple in structure, working stability is provided.
The hermetically-sealed construction of electric kettle discharging mouth, comprise top cover, be located at the button of top cover end face, be positioned at rotation-limited piece and the gathering sill of button below, power transmission shaft with phase fit in the middle of the rotation-limited piece, and be located at the outer back-moving spring of power transmission shaft, it is characterized in that establishing in described power transmission shaft lower end an interlock cross bar assembly, described interlock cross bar assembly comprises the interlock cross bar, seal cover and torsion spring, one end of described interlock cross bar is rotatably connected on a fixed bar, the delivery port black box comprises the make progress seal cover of fastening kettle delivery port of the interlock cross bar other end, be located at kettle mouth sealing ring corresponding with the kettle delivery port on described seal cover and the fixing fixed block of kettle mouth sealing ring and seal cover, the outer socket of described fixed bar one torsion spring, one end bullet holder of described torsion spring is in the bottom surface of seal cover.
The Baltimore groove that described seal cover is an opening upwards, the Baltimore groove size and shape is corresponding with the size and shape of the kettle delivery port covered mutually.
The black box of described power transmission shaft is comprised of the lower disc limited block of establishing in the middle of the power transmission shaft bottom and the sealing ring that is located at the power transmission shaft middle lower portion.
Beneficial effect of the present invention is for passing through button, contact between power transmission shaft and interlock cross bar assembly connects the switching of mutually having worked in coordination with delivery port, relatively independent between interlock whippletree assembly and power transmission shaft, only under button, driving at a certain distance power transmission shaft presses down, could promote the fixed bar rotation of interlock cross bar around an end, make seal cover leave delivery port, when eliminating the lower to after power of button, the interlock cross bar rotates and resets under the screen resilience effect of torsion spring, power transmission shaft is lifted under the returning spring effect, seal cover covers tightly delivery port, thereby avoided the offside seal cap sealing that causes of power transmission shaft not tight, and after lifting on power transmission shaft, make the lower disc limited block of power transmission shaft lower end seal connecting hole, even kettle body side falls, kettle body water outlet end can not leak yet.
