Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a citrus juicer for squeezing citrus juice.

It would be convenient if a citrus juicer with a speed reducer for squeezing citrus juice, which is suitable for a rotation speed several tenths of that of a juicer, is attached to the juicer body as an attachment, and the juicer body can be used in a wide range of ways. ,
Juice may infiltrate the juicer body through the speed reduction mechanism.

Therefore, there is a need for a simple means to prevent juice from entering the juicer body.

The present invention meets these demands, and one embodiment thereof will be described below with reference to the accompanying drawings.

In the figure, 1 is an electric motor, and screw 3 is attached to the juicer body 2.
It is installed by

Reference numeral 4 designates the shaft of the electric motor 1, the upper part of which is removably fitted into a connector 5 integrated with the input shaft 6 of the speed reduction mechanism, and is configured to transmit 10 rotations of the electric motor.

Reference numeral 7 designates a gear case lid that covers the speed reduction mechanism of the filter 10, which has a small hole 9 for straining the juice, and is provided with ribs 7a on the upper surface and ribs 7b all around the lower end.

The juice falling from the small hole 9 is filtered by the rib 10a of the filter.
, enters the container 8 below the filter 10 along the rib 7b, and prevents the juice from leaking into the main body 2 from the gear case lid 7.

11 is a bearing of the input shaft 6 press-fitted into the gear case lid 7;
Reference numeral 12 denotes an oil seal that prevents liquid from entering the reduction mechanism section from the input shaft 6, and is press-fitted into the gear case lid 7.

13 is a gear assembled to transmit 60 rotations of the input shaft, and with a retaining ring 14, the gear 13 is connected to the input shaft 6
The connector 5 has a structure that prevents it from being pulled out from the gear case lid 7.

15 is a gear for transmitting the reduced rotation to the internal gear 19a of the cone 19, and is integrated with the output shaft 16.

The output shaft 16 is held by a bearing 1T press-fitted into the filter 10, and an oil seal 18 also press-fitted into the filter 10 prevents water from entering the deceleration mechanism section from the output shaft 16 and oil from the deceleration mechanism section. Prevent spills.

One side of the output shaft 16 is connected to a gear of the speed reduction mechanism and has a structure that prevents it from coming off.

The cone 19 is fitted onto a shaft 20 that is integrated with the filter 10, and rotates around the shaft 16 at a rotational speed several tenths of that of the electric motor 1 by the rotational torque transmitted to the internal gear 19aK.

Numeral 21 is a screw for fixing the gear case lid 7 to the filter 10, and the seal 22 sandwiched between the rib 10a of the filter 10 and the rib 7a of the gear case lid 7 maintains the airtightness of the speed reduction mechanism section.

The filter 10 fits over the container 8, and the container 8 is connected to the main body 2.
It is fitted onto the top.

Reference numeral 23 denotes the surface to be cut of a citrus fruit, which has an outer skin 24 on the outside and a pulp 25 wrapped in an inner bag on the inside.

Next, the operation of this embodiment will be explained.

When the electric motor 1 is rotated in the state shown in the figure, rotation is transmitted from the shaft 4 to the connector 5, and the input shaft 6 rotates at high speed.

A rotation speed that is a fraction of that of the electric motor 7 is transmitted to the output shaft 16 by a speed reduction mechanism such as the gear 13 .

Next, the speed is further reduced by an internal gear 19a integrated with the gear 15 and the cone 19, and the cone 19 rotates around the shaft 20 at a speed several tenths of that of the electric motor 1.

Therefore, when the cut side of the object to be cut 23 is pressed against the cone 19, only the pulp 25 is crushed by the cone 19, and the juice, part of the pulp 25, and part of the inner bag are transferred to the filter 10.
The juice falls through the small hole 9 into the container 8 and is collected.

In addition, the juice that flows into the gear case lid 7 from some of the small holes 9 along the filter ribs 10a flows into the gear case lid 7.
Because of the ribs 7b, the water does not flow up the gear case lid 7 into the main body 2 and accumulates in the container 8.

As described above, the present invention has a simple configuration in which a rib is provided on the gear case lid of the speed reduction mechanism, so that juice does not flow into the main body, preventing trouble with the motor, and its practical value is great.
