A citrus juicer includes a vessel configured to receive a cone segment, the cone segment defining a conduit extending from a shaft and a plurality of slits extending circumferentially thereon, a rubber spring vertically aligned with an opening of the conduit, and a reamer element in operable communication with the rubber spring. The rubber spring is fixedly mounted to a sprint support member, the spring support member coupled to the conduit extending from the shaft of the cone segment. The rubber spring further defines a centrally disposed projection. When a force is applied to a top portion of the reamer element, the rubber spring is in a compressed state such that the centrally disposed projection engages the spring support element to displace the reamer element in a vertical direction with respect to the shaft of the cone element.

The present disclosure relates to a grinding machine and an assembling method thereof. The grinding machine includes a container, a grinding assembly, and a sealing base. A bottom portion of the container defines a juice outlet. The sealing base seals the juice outlet. The sealing base is detachably connected with the container. The grinding assembly includes a cutting tool, an upper grinding disc, and a lower grinding disc arranged in sequence from top to bottom. A drive shaft is rotatably arranged on the sealing base. The cutting tool and the lower grinding disc are fixed on the drive shaft. The upper grinding disc is fixed on the sealing base. A first positioning step configured to position the upper grinding disc is formed on an inner wall of the juice outlet. A first elastic sealing piece is arranged between the upper grinding disc and the first positioning step.

A citrus juicer is set forth including a deformable container forming an extracting chamber to receive at least one portion of citrus fruit, and having an opening for introducing the citrus fruit; a frame forming a socket to receive the deformable container; a dividing ridge having a cross-section with a tip oriented towards the extracting chamber, and the dividing ridge being arranged to divide the citrus fruit when the citrus fruit is pressed against the tip thereof; a pressing system to exert pressure on the extracting chamber and against the socket. A method for extracting juice from citrus fruit is also disclosed.
