Claims

1. The leak-proof method of the bean grinding coffeepot with the elastic valve for leak prevention comprises an upper grinding brewing cavity, a lower leak-proof cavity, a motor shaft and a grinder assembly, wherein the motor shaft, the elastic valve, a transmission hole and a leak-proof interlayer are combined into a relatively sealed structure;

the leakage-proof method comprises the following steps:

the step of connecting the upper crushing brewing cavity in a separating way:

crushing and brewing:

a flow guiding step:

and (3) outflow step:

2. The method of claim 1, wherein the grinding step requires only one set of driving components for grinding coffee beans and stirring coffee, the upper grinding brewing chamber is locked on the large body, and the blade component at the bottom of the upper grinding brewing chamber and the upper driving component are in driving connection with the lower driving component of the motor of the large body.

3. The method of claim 1, wherein in the grinding step, the grinder assembly is a grinder blade assembly disposed in the upper grinding and brewing chamber, and the motor drives the grinding blade on the knife shaft to rotate to grind the coffee bean food in the upper grinding and brewing chamber.

4. The method of claim 1, wherein in the comminuting step, a deagglomerator assembly and a filter device are disposed within the upper comminuting brewing chamber and a lower leak-proof chamber is disposed below the upper comminuting brewing chamber.

5. The method of claim 1, wherein in the pulverizing step, the upper pulverizing brewing chamber is a chamber for pulverizing the food and brewing the food, and the liquid after brewing the food is guided out of the chamber.

6. The method of claim 1, wherein during the brewing step, after the coffee grounds in the upper chamber are dissolved, the filter screen separates the coffee grounds from the liquid in sections, and the coffee liquid flows out of the outer container through the outlet.

7. The method of claim 1, wherein in the step of preventing leakage, the upper pulverizing brew chamber is open upward; the motor shaft is vertically or obliquely arranged, and the bottom of the upper crushing and brewing cavity is in sleeve joint or butt joint transmission with the motor shaft in a relative motion way.
