Description
Technical field
The present invention relates to the discharging device of a kind of coffee machine, particularly a kind of coffee machine.
Background technology
The water nozzle of common coffee machine is arranged on the top cover, and top cover is hinged on the fuselage, an end of water nozzle; Be the water side, be positioned at the top of brewing basket and towards brewing basket, the other end of water nozzle communicates with water tank through taking over; When opening or closing top cover, water nozzle all will be along with top cover rotates together.
In coffee machine when work,, because top cover is in closed condition, the coffee outlet below the brewing basket is closed, so the space that brewing basket belongs to is airtight, water nozzle is positioned at this space; When infusing coffee, high-temperature water is ejected into brewing basket through water nozzle and carries out brewing of coffee under pressure, and at this moment, this confined space is a pressure space, after brewing end, and the still residual high-temperature water that has part to be sealed in the adapter that water nozzle reaches with it communicates by pressure.At this moment, if the user does not have with containers such as coffee pots the coffee water conservancy diversion in the brewing basket to be come out in advance, and discharge the pressure in the above-mentioned space; Let residual high-temperature water be sprayed onto in the brewing basket, and directly open top cover through water nozzle, then the water side of water nozzle along with the rotation of top cover outside brewing basket; Even possibly face toward the operator, at this moment, the residual high-temperature water that loses after envelope is pressed will spray water nozzle; And possibly be sprayed onto on operator's the body, cause scald.Therefore, there is serious potential safety hazard in this coffee machine.
Summary of the invention
The object of the invention aim to provide a kind of simple and reasonable, cost of manufacture is low, connection is reliable, good seal performance, safe coefficient high, the discharging device of the coffee machine of flexible operation, to overcome weak point of the prior art.
Press the discharging device of a kind of coffee machine of this purpose design; Comprise the water nozzle between top cover and brewing basket; One end of water nozzle is towards brewing basket; The other end of water nozzle communicates with water tank through taking over, and what it is characterized in that the other end of water nozzle rotates is socketed in the adapter, and sealing ring is crimped between the other end and adapter of water nozzle.
Said discharging device also comprises water nozzle bracket, and water nozzle bracket is arranged on the fuselage inwall, and water nozzle bracket is provided with locating hole, and the other end of water nozzle is set in the locating hole.
The outer wall of the other end of said water nozzle is provided with stopping boss and limited step, and stopping boss and limited step are resisted against two ends of locating hole respectively.
Said water nozzle bracket is provided with hangers, and hangers is hooked on the fuselage inwall.
The inboard of said top cover is provided with the guiding ejection piece that the end that is used to promote water nozzle rotates, and the side of this guiding ejection piece is wedge shape.
One end top of said guiding ejection piece and water nozzle joins.
Said guiding ejection piece relies on an end thin thickness at brewing basket center, relies on an end thicker at brewing basket edge.
The outer wall of said adapter is provided with groove, and sealing ring is arranged in the groove.
Said sealing ring is more than two, coaxial up and down setting.
Top cover among the present invention is when opening, and suitable is smooth and easy, even the still residual high-temperature water that has part to be sealed by pressure in the adapter that water nozzle reaches with it communicates; When the instantaneous pressure of uncapping discharges; Also can only be ejected in the brewing basket, and can not be ejected into outside the coffee machine, more can not be ejected on one's body the operator; Therefore eliminated hidden danger, its safe coefficient is improved greatly.
Top cover among the present invention is when opening, and an end of water nozzle is the center top that the water side is positioned at brewing basket, when needs take out brewing basket, with hand one end of water nozzle is dialed to its top of leaving brewing basket towards water tank one side and gets final product.When closing top cover, the guiding ejection piece on the top cover is along with top cover presses down gradually an end of water nozzle from a side pressure of water tank to the top, center of brewing basket, and can carry out coffee brewing next time this moment, and its operation is quite flexible.
The other end of the water nozzle among the present invention is realized interference fits through sealing ring with taking over the end, can prevent effectively that sealing leaks good seal performance.Water nozzle bracket can be strengthened the degree of stability of water nozzle, prevent rotation because of water nozzle make water nozzle and take between occur looseningly, guarantee to connect reliable, prolong its service life.
