Summary of the invention
The technical problem that the utility model will solve provides a kind ofly can seal the coffee machine water inlet automatically after mentioning water tank, anti-sealing overflows the reverse sealing device of fuselage, and the utility model also provides a kind of coffee machine that can seal water inlet automatically.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: the reverse sealing device of a kind of coffee machine; Comprise base and tubulose delivery port, it is characterized in that said reverse sealing device comprises that also the valve gap that places on the base, the valve pocket, the said delivery port that are formed by base and valve gap are communicated with valve pocket; The elastomeric element that is provided with the base leak-stopping in the said valve pocket and connects base leak-proof valve and base bottom wall; The top of said base leak-proof valve is provided with boss, and the top of said valve gap has water inlet, said water inlet less than the radial dimension of base leak-proof valve greater than the radial dimension of boss.The base leak-proof valve can make boss pass water inlet under the effect of elastomeric element and withstand the water tank leak-proof valve.
In a preferred version of the utility model, be lined with sealing ring on base leak-proof valve top.
The described elastomeric element of the utility model is a spring.
The described boss of the utility model is designed to cylindric or coniform.
The radial section of the described base leak-proof valve of the utility model is circular, and periphery is provided with the axial projections that can embed valve pocket.
In addition; The utility model also provides a kind of coffee machine that said reverse sealing device is housed; Comprise water tank and base, said water tank bottom is provided with water outlet of water tank, is provided with outward extending flange at the water outlet of water tank periphery; By being provided with water tank leak-proof valve and difference overhead in the groove that flange surrounded in the water tank spring of water tank bottom and water tank leak-proof valve; Said reverse sealing device is located on the coffee machine base, and its water inlet and water outlet of water tank are relative, and the radial dimension of said boss is less than or equal to the size of water outlet of water tank.
Because the utility model adopts reverse sealing device, when taking away water tank, the base leak-proof valve can withstand sealing ring under the effect of elastomeric element; Sealing outlet rapidly; Simple in structure, good sealing effect can prevent that the aqueous reflux fuselage from causing scald or other unnecessary loss outward; And then the service behaviour of raising complete machine, it is more convenient to use.

Fig. 2 is the structural representation of the utility model base leak-proof valve;
Fig. 3 is the structural representation of prior art coffee machine water tank;
Fig. 4 is the structural representation of prior art coffee machine base.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
Reverse sealing device as shown in Figure 1; Comprise the tubulose delivery port 11 of base 1, base 1 bottom, on base 1, be equipped with valve gap 2, base 1 surrounds valve pocket 12 with valve gap 2; Delivery port 11 is communicated with valve pocket 12, and valve pocket 12 inside are provided with base leak-proof valve 4 and elastomeric element 5.Elastomeric element 5 one ends place on base 1 bottom interior wall; Other end overhead is in base leak-proof valve 4; Can promote base leak-proof valve 4 to moving away from base 1 diapire direction, the top of base leak-proof valve 4 is provided with boss 41, and the top of valve gap 2 has water inlet 21; Water inlet 21 less than the radial dimension of base leak-proof valve 4 greater than the radial dimension of boss 41; Be water inlet only allow boss 41 through and do not allow base leak-proof valve 4 integral body to pass through, the radial dimension of boss 41 is less than or equal to the size of water outlet of water tank 7, base leak-proof valve 4 can make boss 41 pass water inlet 21 under the effect of elastomeric element 5 and withstand water tank leak-proof valve 8.
A preferred version as the utility model; Be lined with sealing ring 3 on the top of base leak-proof valve 4; When base leak-proof valve 4 pushes up to valve gap 2 under elastomeric element 5 acts on, can make the sealing effectiveness between base leak-proof valve 4 and the valve gap 2 better, sealing ring 3 can be designed to circular; To fit into the shape at the mouth of a river, do not get rid of the possibility of other shapes certainly yet.
As another preferred version of the utility model, described elastomeric element 5 is a spring.
As another preferred version of the utility model, the boss 41 on base leak-proof valve 4 tops can be cylindric or coniform, backs down water tank sealing valve 8 so more easily.
Another preferred version as the utility model; The radial section of base leak-proof valve 4 is designed to circle; Periphery is provided with axial projections 42; Projection 42 has increased the axial length of leak-proof valve 4 and can press close to base 1 sidewall, therefore can make base leak-proof valve 4 more firmly embed valve pocket 12, to avoid and rolls.
Coffee machine cisten mechanism in the prior art as shown in Figure 3; Be provided with outward extending flange 10 at water outlet of water tank 7 peripheries; In the groove that flange 10 is surrounded, be provided with water tank leak-proof valve 8 and difference overhead in the water tank spring 6 of water tank bottom and water tank leak-proof valve 8, water tank leak-proof valve 8 tops are provided with projection, and the end of projection expands into hemispherical; Can make water tank leak-proof valve 8 be embedded in water outlet of water tank 7; When water tank 9 did not insert coffee machine, the top boss end of water tank leak-proof valve 8 can be sealed water outlet of water tank 7, thereby prevented that water tank 9 internal water from flowing out.Simultaneously, the elastomeric element 5 of reverse sealing device is in the state of flicking, and is as shown in Figure 1, and base leak-proof valve 4 tightly withstands valve gap 2 and flows out to stop fuselage interior water under the effect of elastomeric element, realize the water shutoff function.After inserting water tank 9; The flange 10 extruding base leak-proof valves 4 of water tank 9 bottoms are subjected to displacement it downwards, and elastomeric element 5 is in compressive state; Boss 41 above the base leak-proof valve 4 is pushed water tank leak-proof valve 8 open simultaneously; Water tank leak-proof valve 8 overcomes the elastic force of water tank spring 6, and water tank 9 is communicated with fuselage, and the water in the water tank 9 flows to fuselage through the gap between the gap between water tank leak-proof valve 8 and the water outlet of water tank 7 and base leak-proof valve 4 and the base 1.Elastomeric element 5 ability quick-recovery raw footages after mentioning water tank; Thereby reach the purpose of sealing water inlet 21; Simultaneously, water tank leak-proof valve 8 also resets rapidly under the effect of water tank spring 6, prevents that the water tank internal water from flowing backwards out; Not only can avoid scalding but also can improving the overall performance of fuselage, it is more convenient to use.
More than be merely a specific embodiment of the utility model, but the design concept of the utility model is not limited thereto, all insubstantial modifications of utilizing this design that the utility model is made all fall within the protection domain of the utility model.
