Description

[Technical Field]

[0001] This utility model relates to a squeezing structure for a juicer, belonging to the field of juicers. [Background Technology]

[0002] With the advancement of technology and the improvement of living standards, slow juicers or juicers are becoming increasingly popular. The main structure of a slow juicer or juicer includes a feeding assembly and a juicing assembly connected to the feeding assembly. The juicing assembly usually includes a screw and a juicing cup. Its principle is to allow the screw to rotate inside the juicing cylinder, thereby squeezing the food to be squeezed into liquid between the screw and the juicing cylinder.

[0003] When food is squeezed, it tends to escape upwards, especially when the food is large or hard. To solve this technical problem, traditional juicers can only accommodate smaller food items or require manual pressing with a lever to squeeze the food downwards, which is cumbersome and results in low juicing efficiency. [Utility Model Content]

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a squeezing structure for a juicer.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A squeezing structure for a juicer includes a feeding housing and a squeezing assembly. The squeezing assembly includes a juicing cup and a screw disposed inside the juicing cup. An upper limit platform extends from the inner wall of the feeding housing toward the center of the screw. The upper limit platform is located above the screw. A temporary squeezing space is formed between the bottom of the upper limit platform, the inner wall of the juicing cup, and the side of the screw. When the food is guided into the temporary squeezing space by the screw and squeezed, the upper limit platform prevents the food from escaping upwards.

[0007] The beneficial effects of using this utility model are as follows:

[0008] Firstly, this invention creates a semi-enclosed temporary squeezing space by setting an upper limit platform on the inner wall of the feeding shell, which blocks the top of the originally upward-open juicing chamber. This creates a space that is limited at the top and open on the side. When the juicer is working, the rotating screw draws the food into the temporary squeezing space. As the food is being squeezed, its top is blocked by the upper limit platform, preventing it from escaping upwards. This significantly improves the squeezing efficiency and eliminates the need for manual pressing of the pressing rod to squeeze the food downwards, simplifying the user's operation and optimizing the user experience.

[0009] Secondly, the upper limit platform is located on the inner wall of the feeding shell and above the screw. This means that there is also space above the upper limit platform to accommodate ingredients. When users put in a large amount of ingredients at once, from a vertical perspective, the ingredients will be distributed around the screw projection, rather than just on one side of the screw. This makes the juicer's center of gravity more stable during operation and less prone to shaking. At the same time, manufacturers can also set a larger feeding shell, allowing users to put in more ingredients at once, making it more convenient for users.

[0010] Preferably, the feeding housing is provided with an upper feeding channel located above the upper limit platform, and the juicing cup is also provided with a lower feeding channel located below the upper limit platform. The lower feeding channel is located on the side of the screw and is opposite to the temporary extrusion space.

[0011] Preferably, the projection of the screw in the horizontal direction is located inside the projection of the upper feed channel in the horizontal direction.

[0012] Preferably, the top of the upper feeding platform is provided with a first guide slope, and the food enters the lower feeding channel from the upper feeding channel along the first guide slope.

[0013] Preferably, the lower feed channel is provided with a second guide slope, and the food enters the side of the screw along the second guide slope.

[0014] Preferably, the lower feed channel is provided with a second guide slope, and the food enters the side of the screw along the second guide slope. The first guide slope and the second guide slope are arranged opposite to each other, and the second guide slope is located below the first guide slope.

[0015] Preferably, the projection of the upper limit station in the horizontal direction does not intersect with the central axis of the screw.

[0016] Preferably, the screw is provided with a positioning shaft, which extends to the top of the screw and forms a positioning protrusion. The inner wall of the feed housing is provided with a fixing arm extending toward the positioning shaft, and the fixing arm is provided with a limiting hole that cooperates with the positioning protrusion.

[0017] Preferably, the fixed arm and the upper limit platform are an integral structure.

[0018] Preferably, the fixed arm protrudes beyond the edge of the upper limit platform.

[0019] Preferably, the thickness of the thickest part of the fixed arm is 5 to 30 mm.

[0020] Preferably, the height of the screw is greater than or equal to 8 centimeters.

[0021] Preferably, the vertical distance between the bottom surface of the upper limit station and the top of the screw is less than or equal to 30 mm.

[0022] Preferably, the projection area of ​​the upper limit station in the horizontal direction covers 5% to 45% of the projection area of ​​the upper feed channel in the horizontal direction.

[0023] Preferably, the feeding shell and the juicing cup are an integral structure.

[0024] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0030] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0031] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” that indicate orientation or positional relationship are used only for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0033] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] Example 1:

[0035] like Figure 1-4 As shown, this embodiment includes a feeding housing 1 and a pressing assembly 2. The pressing assembly includes a juicing cup 21 and a screw 22 disposed inside the juicing cup 21. An upper limit platform 11 is provided on the inner wall of the feeding housing 1 extending toward the center of the screw 22. The upper limit platform 11 is located above the screw 22. A temporary pressing space 3 is formed between the bottom of the upper limit platform 11, the inner wall of the juicing cup 21, and the side of the screw 22. When the food is guided into the temporary pressing space 3 by the screw 22 and is pressed, the upper limit platform 11 prevents the food from escaping upward.

[0036] Firstly, in this embodiment, an upper limit platform 11 is provided on the inner wall of the feeding housing 1, which blocks the top of the originally upward-open juicing chamber. The bottom of the upper limit platform 11, the inner wall of the juicing cup 21, and the side of the screw 22 form an upper limit and a semi-enclosed temporary squeezing space 3 that is open on the side. When the juicer is working, the rotating screw 22 draws the food into the temporary squeezing space 3. As the food is squeezed, its top is blocked by the upper limit platform 11, preventing it from escaping upwards, significantly improving the squeezing efficiency and eliminating the need for manual downward squeezing with a pressing rod. To simplify user operation and optimize the user experience, the upper limit platform 11 is located on the inner wall of the feeding shell 1 and above the screw 22. This means that there is also space above the upper limit platform 11 to accommodate ingredients. When users put in a large amount of ingredients at once, from a vertical perspective, the ingredients will be distributed around the projection of the screw 22, rather than just on one side of the screw 22. This makes the juicer more stable in terms of center of gravity during operation and less prone to shaking. At the same time, the manufacturer can also set a larger feeding shell 1, allowing users to put in more ingredients at once, making it more convenient for users to use.

[0037] See Figure 4 A temporary squeezing space 3 is formed between the bottom of the upper limit platform 11, the inner wall of the juicing cup 21, and the side of the screw 22. In this embodiment, the inner wall of the juicing cup 21 is specifically the inner wall below where the upper limit platform 11 is located. When the screw 22 is rotated to any angle, the side of the screw 22 always refers to the side of the screw 22 that is close to the inner wall of the juicing cup 21.

[0038] See Figure 2 The plane containing the bottom surface of the upper limit platform 11 serves as the dividing line. Above the dividing line AA' is the feeding shell, which contains an upper feeding channel 12. Below the dividing line AA' is the juicing cup 21, which contains a lower feeding channel 13. The lower feeding channel 13 is located on the side of the screw 22 and is opposite to the temporary extrusion space 3. The user feeds ingredients through the feeding channel. After entering the lower feeding channel 13, the ingredients come into contact with the side of the screw 22 away from the temporary extrusion space 3, facilitating the entry of the ingredients into the temporary extrusion space 3. At the same time, the user can feed a large amount of ingredients at once and temporarily store them in the upper feeding channel 12. As the ingredients in the temporary extrusion space 3 are consumed, they will fall from the upper feeding channel 12 into the lower feeding channel 13, eliminating the need for the user to frequently add ingredients manually and improving convenience.

[0039] It should be noted that in this embodiment, the feeding shell 1 and the juicing cup 21 are preferably an integral structure, which helps to improve the stability of the juicer during operation and facilitates user disassembly and assembly. In other embodiments, the feeding shell and the juicing cup can also be separate structures. All these embodiments fall within the protection scope of this utility model.

[0040] See Figure 2 The rotation axis R of the screw, the horizontal projection S1 of the screw 22, and the horizontal projection S2 of the upper feed channel 12 are all specified. The horizontal projection S1 of the screw 22 is located inside the horizontal projection S2 of the upper feed channel 12, and the horizontal projection of the screw 22 is positioned as close as possible to the middle of the horizontal projection of the upper feed channel 12. With this configuration, when the user puts a large amount of food into the feed channel at once, the center of gravity of the feed channel and the rotation axis of the screw 22 are as close as possible, which can improve the stability of the juicer during operation and prevent shaking.

[0041] The upper limit platform 11 is provided with a first guide slope 14. The food enters the lower feed channel 13 from the upper feed channel 12 along the first guide slope 14, preventing the food from staying on the upper limit platform 11 and failing to fall into the temporary extrusion space 3.

[0042] In order to further guide the ingredients into the temporary extrusion space 3, the second feeding channel is provided with a second guide slope 15. The ingredients enter the side of the screw 22 along the second guide slope 15. With this setting, the ingredients can contact the screw 22 to a greater extent, making it easier for larger ingredients to enter the temporary extrusion space 3.

[0043] In this embodiment, the first guide slope 14 and the second guide slope 15 are preferably arranged opposite to each other, with the second guide slope 15 located below the first guide slope 14. That is, the first guide slope 14 and the second guide slope 15 have opposite inclination directions. This arrangement facilitates the entry of ingredients from the upper feeding channel 12 into the lower feeding channel 13, making the feeding process smoother.

[0044] Figure 2 In the figure, S3 is the projection of the upper limit platform 11 preferably in the horizontal direction. As shown in the figure, the projection S3 of the upper limit platform 11 preferably in the horizontal direction does not intersect with the central axis of the screw 22. This setting is to ensure that the upper limit platform 11 can prevent the food from escaping upward while maximizing the cross-sectional area of ​​the lower feed channel 13, so that the product can accommodate as much food as possible into the temporary extrusion space 3.

[0045] The height of the screw 22 is preferably greater than or equal to 8 cm. If the height of the screw 22 is less than 8 cm, the size of the temporary compression space 3 may be too small to accommodate large food items.

[0046] In this embodiment, the screw 22 is provided with a positioning shaft, which extends to the top of the screw 22 and forms a positioning protrusion 23. The inner wall of the feed housing 1 is provided with a fixing arm 16 extending towards the positioning shaft. The fixing arm 16 is provided with a limiting hole 17 that cooperates with the positioning protrusion. When the screw 22 is squeezing food, it is easy to shake. The positioning protrusion 23, the fixing arm 16, and the limiting hole 17 can reduce the shaking of the screw 22 and improve the stability of the juicer during operation. In this embodiment, the positioning protrusion 23 and the limiting hole 17 are preferably made of metal, which can improve wear resistance and prevent plastic from being worn into the fruit and vegetable juice and harming human health.

[0047] To further improve the stability of the limiting position, the thickness of the thickest part of the fixed arm 16 is 5 to 30 mm. If it is less than 5 mm, the fixed arm 16 may not be strong enough and may be easily damaged during operation. If it is greater than 30 mm, the fixed arm 16 may occupy too much space in the feeding channel and may easily jam the food.

[0048] The fixed arm 16 and the upper limit platform 11 are preferably integrated structures. This design can reduce the number of parts, improve the aesthetics, and reduce gaps, grooves, and other structures inside the product that are difficult to clean.

[0049] See Figure 1 The fixed arm 16 protrudes from the edge of the upper limit platform 11, making the feeding channel form a "U" shaped cross section. This is designed to maximize the cross-sectional area of ​​the lower feeding channel 13, allowing larger volumes of food to pass through.

[0050] The coverage rate of the upper limit platform 11 in the horizontal direction projection S3 covering the upper feed channel 12 in the horizontal direction projection S1 is preferably 5% to 45%. If it is less than 5%, the area of ​​the upper limit platform 11 may be too small, and it may not be able to play a good upper limit effect on the food. When the juicer is working, the food may still escape upward. If it is greater than 45%, the cross-section of the lower feed channel 13 may be too small, and large-diameter food may not be able to enter.

[0051] Example 2:

[0052] Unlike Embodiment 1, the screw 22 in this embodiment does not have a positioning shaft at its top, and correspondingly, there is no fixing arm in the feeding channel. As a result, there will be a gap between the screw 22 and the upper limit platform 11. The vertical distance between the bottom surface of the upper limit platform 11 and the top of the screw 22 is less than or equal to 30 mm. If it is greater than 30 mm, the food may escape from the gap.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
