Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a household machine for mashing food, and more particularly to an extracting device for juice. Background Art A conventional juicer first uses a high-speed rotating blade to pulverize fruits and vegetables, and then filters the juice in the pulverized fruits and vegetables by a high-speed rotating sieve. However, conventional juicers are limited in the production of soft, slender and tough ingredients such as pressed stems and green vegetables. And it smashes the fruits and vegetables by rotating the blades at a high speed, and the high-speed rotation generates a certain amount of heat, thus seriously destroying the freshness and nutrition of the fruits and vegetables.

In order to eliminate the above drawbacks, in the prior art, a juice extractor presses fruits and vegetables between a spiral rotating at a low speed and a circular filter to produce juice or extract. In the juicer, the spiral body and the annular filter screen are arranged in an open top juicer container, the spiral body is in the shape of a spindle, and a plurality of spiral leaves (like thread) are formed in the circumference of the spiral blade. The size is slightly smaller than the annular filter mesh, and the spiral body is formed into a spindle-shaped body and the annular filter mesh forms a gap with a large gap. The food material is cut from the spiral blade at the tip end of the spiral body, and the spiral blade which is rotated by the spiral body is pressed downward, and the gap is downward. Gradually smaller, the ingredients are gradually crushed and crushed, and the juice is squeezed out through the filter to flow into the container to realize the function of juicing.

In the above existing juicer, in order to prevent the grain particles from clogging the annular filter mesh, a ring-shaped brush holder is usually arranged, and a plurality of soft rubber wipers are distributed thereon, and the soft rubber scraper is wound around the ring filter through the ring-shaped brush holder. Relatively rotating, the soft rubber scraper is in contact with the annular filter screen to scrape off the particles of the food material that are blocked in the pores of the annular filter mesh, thereby realizing the function of preventing the grain particles from clogging the filter mesh hole and affecting the juice extraction effect. The power transmission mode of the existing juicer to the annular brush holder is: a lower end of the spiral body connected to the main body is provided with a ring of external teeth, which drives the planetary gear fixed to the bottom of the container, and then drives the lower end through the planetary gear to provide a circle An annular brush holder for the internal teeth to provide rotational power to the annular brush holder. Further, in the existing juicer, the annular screen is divided into upper and lower loops, and the pellets of the food arrive at the bottom of the sieve, and it is considered that the juice has been squeezed out and discharged from the opening of the bottom surface of the annular sieve.

However, existing juicers have the following deficiencies:

1. Due to the use of the bottom of the spiral to transmit power to the ring brush holder, the planetary gears of existing juicers are not easy to clean and may cause juice contamination. In the existing juicer, the rotational power of the annular brush holder is fixed by a planetary gear fixed to the bottom of the container. In order to rotate the planetary gear, a certain gap must be designed between the planetary gear and the container and the rotating shaft. The juice extracted from the ingredients is passed through the bottom of the container. Outflow, there must be some juice between the planet gears and the container and the rotating shaft. At the same time, in order to prevent users from accidentally losing or misplaced small parts, the planetary gears are usually designed to be undetachable or difficult to disassemble. Due to the inability to remove and wash, the juice between the planet gears and the container and the rotating shaft is usually not completely cleaned, which in turn leads to contamination of the freshly squeezed juice.

2. Larger ingredients cannot be processed directly. The food must be cut into the size of the inlet beforehand, which is time consuming and troublesome to use. The ingredients are cut by the spiral leaves at the top of the spiral rotating at a low speed, and then between the spiral and the annular filter for juice extraction. Therefore, the size of the food entering the feed port must be small enough to allow it to be accommodated in the spiral and the ring. The gap between the filters. Due to the compact size of the juicer, and more importantly, due to the size of the juicer output, the gap between the spiral and the annular filter cannot be made very large. At the same time, due to the limitations of this limitation, the diameter of the inlet of the existing juicer is generally set smaller.

3. Juice extraction efficiency is low. The ingredients are cut by the spiral leaves at the top of the spiral rotating at low speed, and then between the spiral and the annular filter for juice extraction. Each cutting amount is an effective depth of the gap between the spiral body and the annular filter screen, and the size of the cross section of the food material fed into the gap between the spiral body and the annular filter screen cannot be larger than the diameter of the feed port due to the limitation of the smaller feed port diameter. . That is to say, the amount of food material that is fed into the gap between the spiral body and the annular filter and cut by the spiral leaves at the top of the spiral body is very limited, and does not reach the maximum load that the juicer can withstand. Therefore, the juice extraction efficiency of conventional juicers is not high.

4. The operation is unstable and easy to get stuck. There is no quantitative feeding structure on the juicer, that is, the working efficiency of the juicer is basically determined by the operator's feeding speed. When the user feeds fast or the user presses the material with the pressing tool, it is easy to cause too much food to be forced between the spiral body and the annular filter, which increases the working load of the product, and too much food is squeezed into the spiral at the same time. Between the annular filter screens, the annular filter screen is easily expanded and deformed, the juice yield of the food material is lowered, and the spiral body is easily caught and stops rotating.

5. Drainage is difficult. The slagging of existing juicers is discharged through the vertical opening of the bottom surface of the annular screen. Since the spiral body needs its own connection host to receive the torque and drive the planetary gear fixed to the bottom of the container through a ring of external teeth at the bottom end, the planetary gear transmits the power to the annular brush holder to provide the power of the annular brush holder. Therefore, the spiral body must protrude from the bottom of the annular filter mesh to achieve the above functions. Therefore, most of the space at the bottom of the annular screen is occupied by the spiral, and the opening of the slag discharge can only be designed to be small. Therefore, the efficiency of slag discharge is low. Especially when extracting high-fiber food materials such as celery, the fibrous structure from which the juice is extracted is difficult to pass through the small slag opening, which causes the residue of the food material to be discharged, which affects the efficiency of juice extraction. In addition, the formation process of the food residue is the entry of the ingredients into the spiral and the annular filter The gap between the two is gradually pressed from top to bottom until the ingredients are considered to have reached the root of the annular filter after the juice is extracted, and the slag outlet of the existing juicer is designed to be directed from the inner wall of the annular filter to the bottom of the annular filter. An opening formed by the center extension, i.e., the residue of the food material needs to be squeezed out along the annular screen to the bottom. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a slow juicer in which the annular brush holder transmission structure is not in contact with the juice to ensure that the freshly squeezed juice is not contaminated.

Further, the transmission member and the upper central shaft of the spiral are coupled by a detachable spline. A slow juicer is also designed, the juicer assembly comprising:

a container having a juice outlet and a slag outlet at the lower end;

a ring brush holder located at the periphery of the annular filter; Further comprising a transmission member, the transmission member is located at the spiral body and the annular filter screen portion, the transmission member is coupled with an upper central shaft of the spiral body, and the transmission member transmits rotational power to the annular brush holder by means of a transmission pair;

Further, a cutting platen is disposed under the transmission member, the cutting platen is fixedly connected with the annular filter screen, and a cutting port is arranged corresponding to the cutting platen and the feeding port; the cutting platen is matched with the transmission member, and the cutting platen is flat under the cutting platen. And conforming to the spiral leaf at the upper end of the spiral body.

Further, the transmission member is conical, and correspondingly, the container cover and the cutting platen are also conical.

Further, a slag discharge port is disposed at a lower end of the side of the annular filter.

Further, a guide piece is extended from both ends of the slag discharge port toward the spiral body, and the guide piece is parallel to an outer tangent line of the spiral blade above the spiral body.

Compared with the prior art, the present invention has the following technical effects:

1. The power of the ring brush holder is transmitted through a transmission member added in the upper part of the spiral body. The transmission structure is easy to disassemble and clean, and the transmission structure is not directly in contact with the juice. The contact parts with the juice are easy to clean, ensuring fresh juice and sanitation. .

2. Retain the advantages of the existing juicer. 1. Use low-speed pressed ingredients to extract juice, fully ensure that the nutrients of the juice are not damaged, and the taste is not changed. At the same time, a low-speed cutting structure is added to the spiral body and the annular filter. The low-speed cutting structure can cut large pieces of food into smaller pieces before the ingredients are introduced into the spiral body and the annular filter to extract the juice, and then the ingredients cut into small pieces are sent between the spiral body and the annular filter. The juice is extracted by pressing, thus eliminating the need for the user to manually cut the ingredients. The low-speed cutting structure can be used as a quantitative feeding device to quickly feed a certain amount of food material that is cut into small pieces into a spiral body and an annular filter to extract juice. By setting the cutting efficiency of the low-speed cutting structure to an appropriate value, such as by adjusting the thickness of the cutting, the number of cutting tools, that is, the number of cuttings per revolution, the cutting efficiency can be adjusted and set to be compared with the juicer. The maximum juice efficiency is matched to achieve the goal of maximizing the efficiency of the juicer. In particular, the low-speed cutting structure can effectively control the maximum amount of the foodstuff entering between the spiral body and the annular filter screen, thereby ensuring the stability of the operation of the juicer, in particular, avoiding the occurrence of the spiral body stopping the rotation due to the overload, and the motor is stuck. The phenomenon.

3. The low-speed cutting structure does not require additional power, and is directly connected to the rotating spiral. The rotation speed is synchronized with the spiral. Therefore, the cutting principle is to use low-speed cutting without destroying the nutrients of the ingredients and the taste of the ingredients. 4. A cutting platen is provided between the low-speed cutting structure and the spiral body to assist in secondary cutting. The cutting platen is fixedly assembled with the annular screen, that is, the cutting platen rotates relative to the low-speed cutting structure and the spiral body. The food material cut by the low-speed cutting structure falls into the gap formed in the cutting platen, and then the food material falls from the gap into the gap between the spiral body and the annular filter screen. In the process of falling into the gap between the spiral body and the filter screen, the larger food material is subjected to secondary cutting by the shearing structure formed by the relatively rotating cutting platen and the spiral body, further ensuring the falling into the spiral body and the ring shape. The size of the food in the gap between the screens is not too large and the size is uniform. This minimizes the load on the motor and further ensures the stability of the load on the motor, avoiding transient large loads damaging the motor performance and affecting the life of the juicer.

5. The slagging structure design of the present invention is to provide a special slag discharge chamber at the bottom of the annular filter screen, and a horizontal slag discharge opening is formed on the slag discharge inner wall, and the size of the slag discharge opening provided thereon is not Subject to other structural constraints, it can be set to a larger suitable size. At the same time, therefore, the slag discharge port is arranged on the inner wall of the lower part of the annular filter screen, and the residue of the food material descends along the annular filter screen to reach the lower part of the annular filter screen and can be arranged in the ring shape. The slag discharge port on the inner wall of the filter screen is directly discharged to improve the efficiency of slagging. For example, when celery is squeezed, the slagging effect is obviously superior to that of the conventional juicer. In addition, the design of the slag discharge port utilizes the centrifugal force generated by the spiral blade of the spiral body to promote the rotation of the food residue, and the residue of the food material is taken out from the slag discharge port to further improve the slagging efficiency.

6. The low speed cutting structure of the present invention is tapered, and the contact area of the food material with the low speed cutting structure can be maximized without increasing the diameter of the conventional juicer. DRAWINGS

As shown in FIG. 2 and FIG. 3, the top surface of the transmission member 300 is provided with a cutting insert 304 to form a low speed cutting structure. A cutting platen 700 is further disposed below the transmission member 300. The cutting platen 700 is fixedly coupled to the annular screen 500 and does not rotate with the spiral body 400. The cutting platen 700 is provided with a feeding opening 701 corresponding to the feeding port 201, and the cut small piece of food material can fall into the gap between the annular screen 500 and the spiral body 400 through the feeding opening 701, the arrow in FIG. Indicates the path to the ingredients. The upper surface of the cutting platen 700 is engaged with the transmission member 300. The lower surface of the cutting platen 700 is a flat surface, and is attached to the spiral blade 401 at the upper end of the spiral body 400. The transmission member 300 has a conical shape that is narrow and wide, and correspondingly, the container cover 200 and the cutting platen 700 are also conical. This shape is designed to increase the length of the cutting edge of the cutting insert 304 while maintaining the shape diameter of the juicer so that it can cut larger sizes of ingredients. At the same time, increase the diameter of the feed port of the juicer to accommodate larger volumes of food, such as an entire apple. The feed port can be designed to resemble an "L" shape with the upper end remaining perpendicular and the lower end angle to an angle perpendicular or nearly perpendicular to the edge of the low speed cutting structure. The feed port can also be designed in a slanted straight type, and the degree of inclination is considered to make the inlet port perpendicular or nearly perpendicular to the edge of the low speed cutting structure.

That is to say, the low-speed cutting structure can control the maximum amount of the foodstuff entering the gap between the spiral body 400 and the annular screen 500, which can effectively prevent the juicer from being stuck due to overload and the deformation of the annular filter 500 to reduce the juice yield. By adjusting the maximum cutting amount of the cutting insert 304, the highest efficiency of the juice extraction of the spiral body 400 and the annular screen 500 can be achieved without overloading.

As shown in Fig. 11, the lower end of the annular screen 500 has a slag discharge port 501. Since it is not restricted by other structures, the slag discharge port 501 can set the size of the slag discharge port according to specific design and functional requirements.

Thus, in the case of more fibrous materials, such as celery, the slagging effect is significantly better than the conventional juicer.

As shown in Fig. 13, a guide piece 502 is extended from both ends of the slag discharge port 501 toward the spiral body 400, and the guide piece 502 is parallel to the outer tangential line of the spiral leaf 401 above the spiral body 400. In this design, the centrifugal force generated when the spiral residue 401 of the spiral body 400 is pushed to push the food residue A is rotated, and the food residue A is guided to the ring 502 to be discharged from the slag discharge port 501, thereby improving the slagging efficiency.

The above is a further detailed description of the present invention in conjunction with the specific embodiments, and it is not intended that the specific embodiments of the invention are limited to the description. It will be apparent to those skilled in the art that the present invention may be practiced without departing from the spirit and scope of the invention.
