DETAILED DESCRIPTION

[0017] Hereinafter, we will describe the embodiments of our invention in detail. Examples of the embodiments are shown in the attached drawings with the same or similar reference numerals to denote the same or similar components or components performing the same or similar functions. The embodiments described below with reference to the drawings are exemplary only to explain the invention, which cannot be interpreted as the limitation on our invention. On the contrary, the embodiments of our invention comprises all changes, modifications, and equivalents in compliance with the spirit and content of the claims.

[0018] As shown in drawing 1 & 2, the said embodiment comprises base body 1 and motor 5 installed in one side of the base body 1. There is a concave-upward chamber, in which an inner turntable gear 3 and an outer turntable gear 4 are disposed, installed on the bottom surface of the base body 1. There is a center gear 2 extending downward from the middle of the top wall of base body's chamber. The center gear 2 meshes with inner turntable gear 3, which sleeves inside the eccentric hole of the outer turntable gear 4 and rotates around the shaft. The shaft of the motor is connected through the base body 1 to the motor gear 6, which drives the outer turntable gear 4. There is a water inlet 21 through the base body 1 installed in the center gear 2 axially. The inner turntable gear 3 whose upper surface is concave-downward is arranged below the water inlet 21. There is also a water outlet 31 installed through the inner turntable gear 3 axially.

[0019] The center gear 2 is arranged around the same axis with the annular positioning plate 7, which installed in the orifice of base body's chamber. the outer turntable gear 4 sleeves in the center hole 71 of the annular positioning plate 7. There is an annular step 11 arranged inside the inner side wall of the base body 1, and the outer turntable gear 4 is sandwiched between the annular step 11 and the annular positioning plate 7. The said inner turntable gear 3 is sandwiched between the top wall of base body's chamber and the outer turntable gear 4. The motor gear 6 is located between base body 1 and the annular positioning plate 7.

[0020] The teeth of the inner turntable gear 3 which are arranged on the inner hole of the turntable, mesh with the center gear 2.

[0021] As shown in drawing 4 & 5, the teeth of the inner turntable gear 3 are arranged on the outer-circle of the turntable. In addition, there is a reduction gear 8, which meshes with the inner turntable gear and center gear 2, arranged inside the outer turntable gear 4.

[0022] When our invention is working, the motor 5 drives the outer turntable gear 4 to rotate through the motor gear 6. At this time, the inner turntable gear 3 rotates not only around the rotation axis of the outer turntable gear 4, but also around the central gear 2, so that the water outlet 31 on the inner turntable gear 3 can move along the spiral trajectory. When water flows into the inner turntable gear 3 through the water inlet 21, and then the water is spiral out of the water outlet 31, which causing that the water is in uniform contact with the coffee powder in all positions and the utilization of soluble substances in coffee powder is increased, so that the extraction rate of the coffee is improved.
