Description

Technical Field

[0001] This invention relates to the field of electric kitchen appliances, and more particularly to a blending blade for a juicer and a juicer itself. Background Technology

[0002] A slow juicer is an evolution of the conventional juicer, its main purpose being to turn fruit into juice to improve taste and make it easier to drink. Slow juicers utilize a low-speed spiral extrusion technology; the lower the extrusion speed, the better. Generally, slow juicers operate at around 75 revolutions per minute, slowly squeezing the juice out like wringing a towel, without damaging the fruit's cell structure and preserving its nutrients. Furthermore, the low-speed juicing process avoids generating high heat, preventing the juice from oxidizing due to heat.

[0003] When a juicer is juicing, large pieces of raw material (such as carrots) need to be cut into smaller pieces so that the larger pieces can also enter the juicing mechanism. Existing cutting blades have the following problems: First, the cutting effect is generally poor, producing large pieces that can get stuck at the outlet and prevent them from entering the juicing mechanism; second, they lack a pushing function, meaning the cut material can only be passively rotated by the blade's rotational force, potentially causing some material to remain at the bottom of the container and unable to enter the juicing mechanism.

[0004] Therefore, those skilled in the art are dedicated to developing a juicer's mixing blade that has a better cutting effect and can actively push the raw materials towards the juice dispensing mechanism. Summary of the Invention

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to improve the raw material cutting effect and increase the efficiency of pushing the raw material into the juice extraction mechanism.

[0006] To achieve the above objectives, the present invention provides a blending blade for a juicer, comprising a base located at the center and three blades radially arranged around the circumference of the base: namely, a first blade, a second blade, and a third blade. The blending blade is installed inside the juicer's feed container, and the bottom of the blending blade's base includes a connecting mechanism that can be connected to the juicer's power mechanism and rotate under the drive of the power mechanism.

[0007] in,

[0008] After the first cutting edge extends from the base, viewed from the side, its outer side slopes upwards, forming an angle A with the horizontal plane at the bottom of the base. The cutting edge of the first cutting edge is positioned in front of the rotating direction of the mixing blade. As the mixing blade rotates, the cutting edge contacts the raw material, completing the cut. Angle A ensures that the cutting edge cuts the raw material at a certain height to achieve the best cutting effect.

[0009] Furthermore, to ensure the cutting effect, the length of the first blade is set according to the following principle: there is a certain gap between its top and the inner wall of the juicer's raw material container, and the preferred value of the gap is 3-5 mm.

[0010] Furthermore, after the first blade is guided out from the base, when viewed from above, its overall shape is arc-shaped, and the direction of the arc curvature is the same as the direction of rotation of the stirring blade.

[0011] The second blade extends outward from the base along the horizontal direction of the base's bottom, with its outer tip flush with the inner side of the raw material tank but not in contact with the inner wall of the raw material tank. The bottom of the second blade is flush with the bottom of the base, and the second blade has a certain thickness to push the raw material at the bottom. When the raw material passes through the discharge port of the raw material tank, it falls from the discharge port into the juice dispensing mechanism under the action of gravity.

[0012] Furthermore, the second blade extends outward along the horizontal direction of the base. When viewed from above, its overall shape is arc-shaped, and the direction of the arc curvature is opposite to the direction of rotation of the stirring blade.

[0013] The third blade extends horizontally outward from the base, its bottom flush with the base. This third blade has a certain thickness, allowing it to move the raw material at the bottom. As the raw material passes the discharge port of the raw material tank, it falls into the juice dispensing mechanism under gravity.

[0014] Furthermore, the third blade extends outward along the horizontal direction of the base. When viewed from above, its overall shape is arc-shaped, and the direction of the arc is opposite to the direction of rotation of the stirring blade.

[0015] Furthermore, the third blade is provided with a cutting edge for assisting cutting on the side that is in the same direction of rotation as the stirring blade.

[0016] Furthermore, viewed from above, the second blade is positioned in the opposite direction to the first blade, with an angle of approximately 180 degrees between them.

[0017] Furthermore, viewed from above, the third cutting edge is positioned between the first and second cutting edges, close to the cutting edge of the first cutting edge; there is a certain angle between the third cutting edge and the first cutting edge, defined as angle B. The preferred value of angle B is approximately 70-80 degrees.

[0018] Therefore, the present invention realizes a mixing blade for a juicer. Based on the traditional two-blade mixing blade, by adding a third blade and reasonably setting parameters such as the length, angle, and position of the three blades, a better cutting effect is achieved, and the raw materials can be pushed into and out of the juicer more efficiently.

[0019] The present invention also provides a juicer including the aforementioned blending blade.

[0020] In addition, the present invention also provides a filter assembly for a juicer, including a first filter and a second filter, wherein the first filter and the second filter are separable.

[0021] in,

[0022] The first filter screen includes a first filter section and a filter grid. The first filter section is located at the bottom front side of the first filter screen. When the filter screen assembly is installed in the juice dispensing mechanism of the juicer, the first filter section is positioned at the bottom near the discharge port of the raw material container. The squeezed fruit and vegetable juice flows to the first filter section under gravity, and after being filtered by the first filter section, it flows out of the juicer through the juice dispensing port of the juice dispensing mechanism.

[0023] The filter grid is connected to the first filter screen and can be integrated with the first filter section or be a detachable structure. The filter grid includes several perforated holes.

[0024] The second filter screen is connected to the filter grid of the first filter screen. When the filter assembly, consisting of the first and second filter screens, is installed in the juice dispensing mechanism of the juicer, the second filter screen is located on the side farther from the discharge port of the raw material container. The second filter screen includes several perforated holes.

[0025] Furthermore, the perforations in the filter grid correspond to those in the second filter screen in terms of their position, size, and number. When the first and second filter screens are combined to form a filter assembly, the perforations in the filter grid and the second filter screen are staggered, forming gaps that constitute the second filtration section. The gap size is approximately 0.3-0.5 mm. This gap size ensures sufficient liquid outflow while preventing residue residue. When the raw material reaches the second filtration section, it is squeezed by the extrusion device. The liquid portion flows out through the second filtration section, while the residue remains inside. After juicing, the filter assembly can be removed from the juicer, and the first and second filter screens can be separated and cleaned. The separated filter screens do not have the small holes of traditional filter screens, resulting in less residue and making them easier to clean.

[0026] Furthermore, the perforations of the filter grid and the second filter screen are rectangular. The rectangular holes are staggered to form long, narrow gaps, which further enhances the effect of blocking residue and extracting juice.

[0027] Furthermore, both the filter grid and the second filter screen include positioning mechanisms with corresponding shapes and sizes. These positioning mechanisms work together to ensure that the perforations of the filter grid and the second filter screen are precisely matched after they are combined, so as to achieve a better filtration effect.

[0028] Furthermore, the shapes of the filter grid and the second filter screen are designed to match the squeezing device of the juicer to achieve the best juice extraction effect.

[0029] Thus, the present invention realizes a filter assembly for a juicer, which forms a second filter section by combining a first filter grid and a second filter screen. Through the aforementioned separable filter structure, an easy-to-clean filter screen is realized.

[0030] In a preferred embodiment of the present invention, the squeezing device of the original sweat machine is a conical worm, and the filter assembly is also conical in shape to match the shape of the worm.

[0031] The present invention also provides a juicer, including the filter assembly described above.

[0032] In addition, the present invention also provides a juicer, including the filter assembly and stirring blade described above.

[0033] This invention also provides a multi-port feeding mechanism for a juicer, including a main container for holding fruit and vegetable raw materials. The main container includes a main feeding port and a main discharging port. The fruit and vegetable raw materials can be fed into the main container through the main feeding port and discharged from the main container through the main discharging port. The multi-port feeding mechanism also includes an auxiliary container, which includes an auxiliary container body, a secondary feeding port, and a secondary discharging port. The space inside the auxiliary container is isolated from the space inside the main container. The fruit and vegetable raw materials are fed into the auxiliary container through the secondary feeding port and discharged from the auxiliary container through the secondary discharging port. The auxiliary container can be configured as an integral part of the main container or as a separable structure from the main container. The number of auxiliary containers can be one or more.

[0034] Since fruits and vegetables have different properties, some raw materials are not suitable for pretreatment in the same way. In this case, the space between the main container and the auxiliary container can be used to process the raw materials in different ways.

[0035] Furthermore, the multi-inlet feeding mechanism of the juicer also includes a main cover body located at the main feeding port of the main container. The main cover body can be set to be separate from the main container or connected to the main container as one piece. When the juicer is juicing, the main cover body is combined with the main container to form a space isolated from the outside inside the main container, so as to ensure hygiene and prevent the fruit and vegetable raw materials in the main container from splashing out.

[0036] Furthermore, the multi-inlet feeding mechanism of the juicer also includes a secondary cover body located at the secondary feeding port of the auxiliary container. The secondary cover body can be set to be separate from the auxiliary container or connected to the auxiliary container as one piece. When the juicer is juicing, the secondary cover body is combined with the auxiliary container to form a space isolated from the outside inside the auxiliary container, so as to ensure hygiene and prevent the fruit and vegetable raw materials in the auxiliary body from splashing out.

[0037] Preferably, the main cover and the secondary cover are integrated as a single unit to simplify the product structure.

[0038] Therefore, the present invention realizes a multi-inlet feeding mechanism for a juicer. By setting an auxiliary container isolated from the main container, raw materials can be put into the main container or the auxiliary container, so that raw materials with different properties can be processed in different ways and juiced, thereby improving the utilization rate of raw materials and reducing the failure rate of the juicer.

[0039] The present invention also provides a juicer including the multi-inlet feeding mechanism described above.

[0040] The present invention also provides a juicer including the multi-inlet feeding mechanism and stirring blade described above.

[0041] The present invention also provides a juicer comprising the multi-inlet feeding mechanism, filter assembly and stirring blade described above.

[0063] The following description, with reference to the accompanying drawings, illustrates several preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0064] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and the present invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components has been appropriately exaggerated in the drawings.

[0065] Example 1

[0066] like Figure 1-4As shown, a juicer's blending blade includes a base 94 located at the center and three blades radially arranged around the base 94: a first blade 91, a second blade 92, and a third blade 93. The blending blade is installed inside the juicer's raw material container 30. The base 94 includes a connecting mechanism at its bottom, which can be connected to the juicer's power mechanism and rotate under its drive. To enhance the blade's strength, the first blade 91, the second blade 92, and the third blade are integrally formed and made of metal. In this embodiment, [the following is a description of the blade design]. Figure 2 and Figure 4 From this perspective, the stirring blade rotates clockwise.

[0067] After the first blade 91 extends from the base 94, its outer side slopes upward when viewed from the side, forming an angle A with the horizontal plane at the bottom of the base 94. The cutting edge 98 of the first blade 91 is positioned on the same side as the rotating agitator blade. When the agitator blade rotates, the cutting edge contacts the raw material, completing the cut. Angle A ensures that the cutting edge cuts the raw material at a certain height to achieve the best cutting effect.

[0068] After numerous experiments, it was found that an angle of 25-35 degrees provides a good cutting effect for most large-sized raw materials.

[0069] Furthermore, to ensure the cutting effect, the length of the first blade 91 is set according to the following principle: there is a certain gap between its top and the inner wall of the juicer's raw material container 30, and the preferred value of the gap is 3-5 mm.

[0070] Furthermore, after the first blade 91 is guided out from the base 94, when viewed from above, its overall shape is arc-shaped, and the direction of the arc curvature is the same as the direction of rotation of the stirring blade.

[0071] After extending from the base 94, the second blade 92 extends outward along the horizontal direction of the bottom of the base 94, with its outer top flush with the inner side of the raw material tank 30, but not in contact with the inner wall of the raw material tank 30. The bottom of the second blade 92 is flush with the bottom of the base 94, and the second blade 92 has a certain thickness, which can push the raw material at the bottom to move. When the raw material passes through the discharge port 97 of the raw material tank 30, it falls from the discharge port 97 into the juice dispensing mechanism under the action of gravity.

[0072] Furthermore, the second blade 92 extends outward along the horizontal direction of the bottom of the base 94. When viewed from above, its overall shape is arc-shaped, and the direction of the arc curvature is opposite to the direction of rotation of the stirring blade.

[0073] The third blade 93 extends outward horizontally along the bottom of the base 94 after being drawn out from the base 94, and its bottom is flush with the bottom of the base 94. The third blade 93 has a certain thickness and can push the raw material at the bottom to move. When the raw material passes through the discharge port 97 of the raw material tank 30, it falls from the discharge port 97 into the juice dispensing mechanism under the action of gravity.

[0074] Furthermore, the third blade 93 extends outward along the horizontal direction of the bottom of the base 94. When viewed from above, its overall shape is arc-shaped, and the direction of the arc curvature is opposite to the direction of rotation of the stirring blade.

[0075] Furthermore, viewed from above, the second blade 92 is positioned in the opposite direction to the first blade 91, with an angle of approximately 180 degrees between them.

[0076] Furthermore, viewed from above, the third blade 93 is positioned between the first blade 91 and the second blade 92, close to the cutting edge of the first blade 91; the third blade 93 forms an angle with the first blade 91. Because the first blade 91 and the third blade 93 have opposite arc-shaped orientations, large pieces of raw material will be trapped between them. Additionally, a blocking rib 96 is provided on the inner wall of the raw material container 30 above the discharge port 97. When large pieces of raw material are brought to the discharge port 97 by the first blade 91 and the third blade 93, they will be trapped by the first blade 91, the third blade 93, and the blocking rib 96, allowing the cutting edge 98 of the first blade 91 to complete the cut. This process is repeated, thus cutting large pieces of raw material into smaller pieces, which ultimately enter the juice extraction mechanism from the discharge port 97.

[0077] After numerous experiments, the best cutting effect was achieved when the angle between the third blade 93 and the first blade 91 was approximately 70-80 degrees.

[0078] Example 2

[0079] This embodiment realizes a juicer, including a raw material tank 30, a power mechanism, a stirring mechanism, and a juice dispensing mechanism;

[0080] like Figure 4 As shown, the stirring mechanism in Example 1 is a stirring blade; the stirring blade is installed at the bottom of the raw material tank 30 and connected to the power mechanism, and can rotate under the drive of the power mechanism. After the raw material is put into the raw material tank 30, it is cut and crushed by the stirring blade, and enters the juice extraction mechanism from the discharge port 97; the juice is squeezed out by the juice extraction mechanism, and finally the original juice extraction is completed.

[0081] Example 3

[0082] like Figure 5-13 As shown,

[0083] A filter assembly for a juicer includes a first filter 210 and a second filter 220, which are separable. In this embodiment, the filter assembly is used with a worm gear 260 as the extrusion device; therefore, the overall shape of the filter assembly is a cone similar in shape to the worm gear 260. Figure 15 The shape comparison between the worm gear 260 and the filter assembly is shown.

[0084] The first filter 210 includes a first filter section 211 and a filter grid 212. The first filter section 211 is located at the bottom front side of the first filter 210. When the filter assembly is installed in the juice dispensing mechanism of the juicer, the first filter section 211 is positioned at the bottom near the discharge port 280 of the raw material container. The squeezed fruit and vegetable juice flows to the first filter section 211 under gravity. After being filtered by the first filter section 211, it flows out of the juicer through the juice dispensing port of the juice dispensing mechanism. The first filter section 211 is a metal screen. The primary function of the first filter section 211 is to filter the juice that automatically seeps out from raw materials with high water content, such as watermelon, and it does not participate in the filtration during the raw material squeezing stage.

[0085] The filter grid 212 is integrated with the first filter section, and the filter grid 212 includes 212 rectangular perforated holes 240.

[0086] The second filter 220 is connected to the filter grid 212 of the first filter 210. When the filter assembly composed of the first filter 210 and the second filter 220 is installed in the juice dispensing mechanism of the juicer, the second filter 220 is located on the side further away from the discharge port 280 of the raw material tank.

[0087] The second filter 220 also includes 212 rectangular perforations 240.

[0088] The perforations 240 of the filter grid 212 and the perforations 240 of the second filter screen correspond to each other in terms of perforation position and size. When the first filter screen 210 and the second filter screen 220 are combined to form a filter assembly, the perforations 240 of the filter grid 212 and the perforations 240 of the second filter screen are staggered, and the staggered parts form gaps. All gaps constitute the second filtration section. The gap size is approximately 0.3-0.5 mm. This gap size ensures that the liquid flows out sufficiently while preventing residue from remaining.

[0089] When the raw material reaches the second filtration section, it is squeezed by the extrusion device. The liquid portion flows out through the second filtration section, while the residue remains inside. After juicing, the filter assembly can be removed from the juicer, and the first filter 210 and the second filter 220 can be separated and cleaned. The separated filter does not have the small holes of a traditional filter and contains less residue, making it easier to clean.

[0090] The filter grid 212 and the second filter screen include positioning ribs 250 and positioning grooves that correspond to each other in shape and size. The positioning ribs 250 and positioning grooves cooperate with each other to ensure that after the two are combined, the perforated holes 240 of the filter grid 212 and the second filter screen also fit together precisely to achieve a better filtration effect.

[0091] Example 4

[0092] The rest is the same as in Embodiment 2, except that the juice dispensing mechanism is equipped with the filter assembly shown in Embodiment 3.

[0093] Example 5

[0094] like Figure 14-17 As shown,

[0095] A multi-port feeding mechanism for a juicer includes a cylindrical main container 81 made of plastic. The circumference and bottom of the main container 81 are formed by plastic walls of a certain thickness, creating a hollow container, which is the main container 81. A circular opening at the top of the main container 81 is the main feeding port 82, through which raw materials can be fed into the interior space of the main container 81. The bottom of the main container 81 includes a main discharging port 83 leading to a juice discharging mechanism 40, through which the raw materials in the main container 81 can enter the juice discharging mechanism 40. (The juice discharging mechanism 40 is not part of the multi-port feeding mechanism of the juicer of this invention, but is included in the accompanying drawings for more accurate description of the technical solution.)

[0096] One side of the circumference of the main container 81 includes an auxiliary container 84 with an approximately square cross-section, made of the same plastic as the main container 81. The plastic walls form a hollow auxiliary container body, with openings at both ends. The end closer to the main feed inlet 82 is a secondary feed inlet 85, and the other end is a secondary discharge outlet 86, which leads to the juice extraction mechanism 40. Raw materials can enter the auxiliary container 84 through the secondary feed inlet 85, be guided by the internal space of the auxiliary container 84, and finally enter the juice extraction mechanism 40 through the secondary discharge outlet 86.

[0097] The space inside the auxiliary container 84 is isolated from the space inside the main container 81, and the raw materials fed into the two spaces will not be mixed before entering the juice extraction mechanism 40. In this embodiment, the raw materials fed into the auxiliary feeding port 85 enter the juice extraction mechanism 40 through the channel inside the auxiliary container 84 and will not enter the main container 81.

[0098] The auxiliary container 84 is designed with a funnel-like structure. The cross-sectional area is largest at the secondary feeding port 85, and gradually decreases from the secondary feeding port 85 to the secondary discharge port 86. This funnel-like design, with its decreasing size, facilitates the input of raw materials. In this embodiment, the cross-section of the auxiliary container 84 is square. From a manufacturing perspective, the cross-section of the auxiliary container 84 can also be circular. Both square and circular shapes are suitable for processing and manufacturing.

[0099] The multi-inlet feeding mechanism of the juicer shown in this embodiment has an auxiliary container 84 and a main container 81 with regular shapes. To save costs, the auxiliary container 84 and the main container 81 are integrally injection molded. If the shapes of the auxiliary container 84 and the main container 81 are more complex and not suitable for integral injection molding, they can also be separate structures, injection molded separately, and then assembled into a whole.

[0100] The multi-inlet feeding mechanism of the juicer shown in this embodiment has one auxiliary container 84. This auxiliary container 84 allows long-fiber raw materials to directly enter the juice dispensing mechanism 40 without entering the main container 81, thus avoiding the problem of entanglement in the stirring mechanism 8. Furthermore, more auxiliary containers 84 can be provided, allowing for different processing methods for the raw materials within different auxiliary containers 84.

[0101] The multi-inlet feeding mechanism of the juicer shown in this embodiment has its auxiliary container 84 integrated into the juicer handle 80. The juicer handle 80 is an outward extension of the edge of the main container 81, and the portion connecting it to the main container 81 requires a relatively thick material to ensure sufficient strength. In this embodiment, this thicker material is designed as a hollow structure, which serves both as part of the handle 80 and as the auxiliary container 84.

[0102] The multi-inlet feeding mechanism of the juicer shown in this embodiment has its auxiliary container 84 as part of the juicer handle 80. The juicer handle 80 and the auxiliary container 84 are integrally injection molded. If the structure of the juicer handle 80 and the auxiliary container 84 is too complex to be integrally injection molded, they can also be separate structures, injection molded separately, and then assembled into a whole.

[0103] The multi-inlet feeding mechanism of the juicer shown in this embodiment also includes a main cover 89 disposed at the main feeding port 82. The main cover 89 is installed on one side of the circumference of the main discharge port 83 and is integrally connected to the main container 81 in a movable manner. The shape of the main cover 89 is configured to simultaneously cover the auxiliary feeding port 85 of the auxiliary container 84. That is, in this embodiment, the main cover 89 and the auxiliary cover are configured as a single unit. During the juicing process, the main cover 89 closes with the main discharge port 83 to prevent raw material splashing and to prevent foreign objects from entering the main container 81. The main cover 89 can also be configured to be detachable and not connected to the main container 81.

[0104] The main container 81, auxiliary container 84, and main cover 89 of the multi-inlet feeding mechanism of the juicer shown in this embodiment are all made of transparent or semi-transparent materials, allowing users to observe the inside and understand the real-time processing of raw materials during use, so as to make corresponding adjustments and facilitate use.

[0105] Example 6

[0106] Figure 18-20 The illustration shows a juicer, including the multi-inlet feeding mechanism of the juicer in Embodiment 6. The juicer also includes a power mechanism, a stirring mechanism 88, and a juice dispensing mechanism 40. The stirring mechanism 88 is installed at the bottom of the main container 81, and the power mechanism drives the stirring mechanism 88 and the juice dispensing mechanism 40. Raw materials fed through the main feeding port 82 are cut and crushed by the stirring mechanism 88, and then enter the juice dispensing mechanism 40 through the main discharge port 83. Raw materials fed through the auxiliary feeding port 85 are directly guided through the auxiliary container 84 and enter the juice dispensing mechanism 40 through the auxiliary discharge port 86. Juice is then extracted through the squeezing action of the juice dispensing mechanism 40.
