FIELD OF INVENTION
[001] The present invention relates to the field of juice extraction devices. The present invention more particularly relates to an improved juicer to yield a thick and pulpy juice, as well as a regular juice without any pulp.

BACKGROUND AND PRIOR ART

[002] Juice extraction device is a kind of home appliance for extracting juice from food such as fruit, herbs, leafy greens, vegetable and the like. Centrifugal juicers with low price and quick juice extraction are the most widely used. Freshly extracted juice is perceived to be healthier and better tasting than the commercially available packaged juices, which may be less fresh and may contain undesirable additives such that the juice no longer is pure juice. Commercially available juices can be purchased in different varieties, most notably clear juices and cloudy juices. In cloudy juices, some of the solid matter of the food product, such as food fibers, is suspended in the juice to give the juice a more substantial texture. Such solid matter is commonly referred to as food pulp or simply pulp. Different consumers may prefer different types of juice; some consumers may not like to have 'bits', i.e. pulp, in their juice and therefore prefer a smooth, clear juice whereas other consumers may prefer the presence of such pulp and will therefore prefer the cloudy juices.

[003] It is therefore desirable to be able to control the pulp content in juice freshly produced with centrifugal juicers. US20130312623 Al discloses a fiber flow controlled centrifugal bowl mechanism including a centrifugal bowl and a mesh filter bracket sleeved at the bottom of the centrifugal bowl. The centrifugal bowl is provided with mesh holes allowing fibers to pass. The mesh size is adjustable to adjust the amount of fibers passing the mesh holes. A drawback of this solution is that the user needs to manually adjust the centrifugal bowl to achieve the desired pulp content in the beverage (juice), which may not be particularly intuitive. Moreover, the relatively complex structure of the centrifugal bowl makes cleaning of the bowl more cumbersome and adds to the cost of the bowl.

[004] WO2015185582 (A1) discloses a centrifugal juicer that can produce juices with user-controlled pulp content in an intuitive and cost-effective manner. There is provided a centrifugal juicer comprising a food shredding element cooperating with a circular sieve comprising a plurality of openings; a motor adapted to rotate the circular sieve, wherein the motor has a variable rotation speed and said openings are dimensioned such that food pulp can be forced through said openings at certain rotation speeds of the motor; and a user interface comprising a pulp content selection function, wherein the variable rotation speed of the motor is controlled by said pulp content selection function.

[005] US6394377 B1 discloses a device for crushing foodstuffs. The device has a housing for a user hold; a motor installed inside the housing; a drum member has an inlet portion for introducing foodstuffs therein and an extended portion; an internal cylindrical member being formed with a plurality of screw knife-edges and being formed with a shoulder along a front portion thereof for blocking a sludge penetration; a screw member being formed with a transferring thread portion including cut portions for pre-crushing, and a crushing thread portion including jaws for increasing a frictional force; and a cap assembled to the drum member for fixing the internal cylindrical member. When a user wants to extract the juice from the fruits, the only thing to do is to replace the internal cylindrical member with the mesh member. The mesh member includes an extraction bag and plural reinforcing ribs. Also in this case, the mesh member is formed with plural knife-edges and front shoulder.

[006] Publication No. CA2855925 discloses a juicer comprising: a filter mesh formed having a plurality of holes for not permitting the residue of food ground in the juicer to pass through, while permitting the pulp of the food to pass; and a cutting blade having at least a portion thereof pressed against one side of the filter mesh, for cutting the residue of food stuck in at least one portion of the plurality of holes.

[007] US8091473 B2 discloses a juice extractor capable of extracting juice from vegetables, fruits or soymilk from beans.

[008] The extractor includes a housing having a draff outlet port and a juice outlet port, a screw having an upper rotary shaft inserted in a rotary shaft hole of the housing and a lower rotary shaft with a plurality of screw spirals formed on an outer periphery thereof, and a mesh drum for extracting the juice toward the juice outlet port, and a rotary brush mounted between the housing and the mesh drum and having a brush holder. On inner wall of the mesh drum, wall blades, which include long blades and short blades, are longitudinally projected at predetermined intervals. The height of projected wall blades is decreased toward the lower part of the wall blades so that the wall blades crush the materials fine as the materials are moved downward by the screw. The outer wall of the mesh drum has a mesh structure so that the juice extracted from the grinded material passes through the mesh structure. It is preferable that the size of the mesh is gradually decreased toward the lower part of the mesh structure since the size of the material particles is decreased toward the lower part of the mesh drum. In addition, since the material is finely grinded at an intermediate height of the mesh drum, the intermediate part of the mesh drum has a sealing structure rather than a mesh structure so as to prevent the draff from being caught in the mesh structure or from slipping through the mesh structure and being mixed with the juice.

[009] Publication No. GB1045243 discloses a method of producing edible fruit or vegetable juice substantially free of insoluble solids, comprising pulverizing the edible fruit or vegetable into a fine pulverulent fluid mass comprising both insoluble solids and juice, mixing a filter aid with the fluid mass and, without prior separation of the insoluble solids from the juice, filtering the fluid mass through a filter comprising a fine mesh sheet material precoated with filter aid to separate the juice from the insoluble solids and collecting the juice thus produced provided that, except when the fruit or vegetable is substantially free from pectin, pectin is removed by depectinisation with a pectic enzyme and inactivation of the enzyme, at least the depectinisation being carried out prior to filtration of the fluid mass.

The base includes two filter nets which are synchronously rotated along with the base and at least one cutter. The two filter nets are an inner filter net and an outer filter net. The two filter nets have meshes which are different in configuration, in shape and in size, so that the two filter nets have different operative filter areas. In this way, the smaller meshes of the inner filter net can filter larger fibers, so the pomace in the juice is less. The meshes of the outer filter net can get a higher juice yield to keep the flavor of fruit. Hence, the invention achieves a dual-filter effect.

[0015] Patent No. 5,784,954 discloses the juice extractor is installed on the uniform base on the circular section with the rectangular protrusion.
