ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a juicer with uniform pressing and, more particularly, to a juicer having a pressing cup that provides a uniform pressing during operation.
2. Description of the Related Art
A juicer is generally used to extract juice from citrus. A typical juicer comprises a base for supporting a dripping cup. A column extends upward from the base and a support plate projects from a side of the column and extends in a horizontal plane. A handle has an end with a spindle pivotally received in the column. A gear is mounted to the spindle to rotate therewith. A vertical rack has a portion housed in the column and meshes with the gear. Thus, the vertical rack is moved vertically when the handle is pivoted. Atop seat is securely attached to an upper end of the vertical rack to move therewith. A pressing cup includes a threaded upper end for threading engagement with a screw hole in the top seat. A reamer is placed on the support plate. In use, fruit with peel (i.e., citrus) is cut by half and a half of the fruit is placed on top of the reamer and the handle is then pivoted to move the vertical rack downward. The pressure cup is moved downward toward the fruit with peel and thus extracts juice from the fruit. The extracted juice flows into a drip cup placed on the base. The threading engagement between the pressure cup and the top seat is designed to allow easy cleaning of the pressure cup. However, the pressing force acting on the pressing cup concentrates on the threading connection. In addition, the half of the citrus tends to shift laterally during pressing, which results in damage to the threaded portion and loosening of the pressing cup. In addition, the other end of the handle to which the user's palm applies force is in the form of a small rod, which renders a difficult and labor-intensive operation. Further, because the user often washes hands before operating the juicer, the user's wet palm might slip from the handle and thus injure the joint.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a juicer having a pressing cup that provides a uniform pressing during operation.
It is another object of the present invention to provide a juicer with an easy-to-operate handle for preventing potential injury to the user's hand.
A juicer in accordance with the present invention comprises a base, a column extending upward from the base, a vertical rod, a top seat, and a juicing device for extracting juice from citrus. The vertical rod has a portion movably mounted in the column and is movable along a vertical direction. The top seat is securely mounted to an upper end of the vertical rod to move therewith, the top seat including a compartment and an annular recessed portion surrounding the compartment. The juicing device comprises a pressing cup and a reamer. The reamer is removably mounted on a support plate that extends from a side of the column. The pressing cup is mounted in the compartment of the top seat and includes a disc having a first side releasably engaged with the top seat and a second side for cooperating with the reamer for extracting juice from a citrus placed on the reamer. The disc has an annular end edge that is received in the annular recessed portion of the top seat.
In an embodiment of the invention, a handle has a first end operably connected to the vertical rod and a second end for manual operation, whereby the vertical rod moves vertically when the handle is pivoted. The second end of the handle comprises a flat portion extending laterally therefrom for easy operation.
The top seat comprises an engaging tube with an inner threading. The first side of the disc includes a conic portion having a stub for threading engagement with the inner threading of the engaging tube. The second side of the disc comprises a skirt that includes a conic inner periphery for cooperating with the reamer for extracting juice from a citrus placed on the reamer. The skirt comprises an outer periphery for user's grasp for proceeding with threading engagement between the stub and the engaging tube of the top seat.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
