Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

Detailed description of the preferred embodiments

A single cup coffee machine drip-proof device, as shown in figure 1, figure 2 and figure 3, including filter screen cover 1, cartridge filter 2, the tube-shape shell 3, valve rod 4, spring 5 and leak protection sealing washer 6, be provided with water inlet 7 on the filter screen cover 1, filter screen cover 1 sets up on cartridge filter 2, form coffee powder cavity 8 between filter screen cover 1 and the cartridge filter 2, the bottom and the lateral wall of cartridge filter 2 all are provided with filter screen 14, the periphery of cartridge filter 2 is established to tube-shape shell 3 cover, form coffee liquid cavity 9 between cartridge filter 2 and the tube-shape shell 3, the bottom of tube-shape shell 3 is provided with coffee liquid outflow hole 10, valve rod 4 is arranged in coffee liquid outflow hole 10 and valve rod 4 can reciprocate along coffee liquid outflow hole 10 under the effect of external force, spring 5 cover is established in the periphery of valve rod 4, spring 5 butt is between the inner wall top surface of coffee outflow hole 10 and the base of valve rod 4, leak protection sealing washer 6 inlay card is in the annular groove at the top of valve rod 4 and leak protection sealing washer 6 is arranged in tube-shape shell Between 3 bottom surfaces and valve rod 4, under the tensile force of spring 5, leak protection sealing washer 6 hugs closely the bottom surface of tube-shape shell 3, and coffee liquid cavity 9 and coffee liquid outflow hole 10 disconnection, when valve rod 4 moved up under the top force effect, valve rod 4 drove leak protection sealing washer 6 and moved up and break away from tube-shape shell 3 bottom surface, and coffee liquid cavity 9 and coffee liquid outflow hole 10 communicate.

In this embodiment, an ejection mechanism 11 for ejecting the valve stem 4 upward is further included, and the ejection mechanism is located at the bottom of the valve stem 4. The top of cartridge filter 2 is provided with a plurality of fixture block 12, and the top of tube-shape shell 3 is provided with a plurality of draw-in groove 13 that uses with fixture block 12 cooperation. The cylindrical shell 3 is screwed into the buckling position after being sleeved into the bottom of the filter cylinder 2. The sieve 14 has 60-80 meshes, is made of nylon or stainless steel, and can pass water and coffee liquid to retain granular powder.

Second, use method

Hot water enters the filter cylinder 2 through the water inlet 7 of the filter screen cover 1, after coffee powder in the filter cylinder 2 is dissolved by the hot water, the coffee liquid flows out of the filter cylinder 2 and enters a cavity between the filter cylinder 2 and the cylindrical shell 3, and at the moment, the coffee powder cannot enter the cavity under the filtering condition of the filter screen. As shown in fig. 2, the leak-proof seal ring 6 is tensioned by the elasticity of the spring 5 under normal conditions, so that the coffee in the cylindrical shell 3 can not flow out, and the coffee chamber 9 is disconnected from the outside.

As shown in figure 3, when the anti-drip device of the single-cup coffee machine is placed in the coffee machine, the valve rod 4 moves upwards to compress the spring 5 and simultaneously drives the anti-drip sealing ring 6 to move upwards to separate from the bottom surface of the cylindrical shell 3 under the action of the ejecting body mechanism 11, at the moment, the cavity inside the cylindrical shell 3 is communicated with the coffee liquid outlet 10, the sealing is released, and the coffee liquid flows out from the bottom of the cylindrical shell 3, so that the coffee liquid cavity 9 is communicated with the outside.

As shown in figure 2, when the anti-dripping device of the single-cup coffee machine is taken out of the coffee machine, the ejection structure 11 is separated from the valve rod 4, the valve rod 4 moves downwards under the action of the restoring force of the spring 5 to drive the anti-dripping sealing ring 6 to move downwards, the anti-dripping sealing ring 6 is contacted with the bottom surface of the cylindrical shell 3 and seals the coffee liquid outlet 10, and liquid cannot flow out from the bottom of the cylindrical shell 3, so that the coffee liquid cavity 9 is disconnected from the outside, and therefore the coffee machine is taken out after coffee is cooked and has no coffee drips on a working table or the ground.

The above description is not intended to limit the present invention, and the present invention is not limited to the above examples. Those skilled in the art should also realize that changes, modifications, additions and substitutions can be made without departing from the true spirit and scope of the utility model.
