Description

Technical Field

[0001] This utility model relates to a juicer with double screw limiting, belonging to the field of juicers. Background Technology

[0002] With the advancement of technology and the improvement of living standards, slow juicers or juice extractors are becoming increasingly popular. The screw is an important component inside the slow juicer, used to rotate and squeeze fruits and vegetables to extract their juice.

[0003] During the squeezing process, the screw is prone to shaking. Therefore, juicers on the market usually have a limiting device at the top of the screw. However, such a structure is still not enough to effectively limit the screw, which may cause the screw to break through the limiting device. At the same time, the wear caused by the friction between the screw and the juicer housing will cause the worn plastic to flow into the juice, which is harmful to the human body. 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 juicer with double screw limiting.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A juicer with dual screw limiting includes a feeding housing and an extrusion assembly. The extrusion assembly includes a juicing cup and a screw disposed within the juicing cup. The bottom of the screw has an annular flange, the upper end face of which abuts against the bottom of the juicing cup to axially limit the screw. The top center of the screw also has a positioning protrusion. The feeding housing also has a fixing device, which has a limiting hole that mates with the positioning protrusion. The positioning protrusion is embedded in the limiting hole to axially and circumferentially limit the screw.

[0006] The beneficial effects of using this utility model are as follows: First, this invention features an annular flange at the bottom of the screw. The annular flange abuts against the bottom of the juicing cup to form an axial limit, preventing the screw from moving upward when squeezing fruits and vegetables. At the same time, the annular flange has a large contact area with the bottom of the juicing cup, which can distribute the pressure on the annular flange, reduce pressure, make the product more durable, and reduce the probability of damage.

[0007] Secondly, this utility model also uses the positioning protrusion at the top of the screw and the fixing device inside the feed housing to limit the screw in the axial and circumferential directions. This not only limits the screw in the vertical direction, but also prevents the screw from shaking in the horizontal direction, thus improving the stability of the product during operation.

[0008] This invention uses the annular flange at the bottom of the screw and the positioning protrusion at the top of the screw to simultaneously limit the screw's position, distributing the pressure to both ends of the screw. This reduces the pressure of the positioning protrusion on the fixing device, making it less likely to be broken, while also reducing the pressure between the annular flange and the bottom of the juicing cup. This minimizes wear on the annular flange, reduces the amount of residue from plastic wear entering the fruit and vegetable juice, improves hygiene and safety, and reduces harm to the human body.

[0009] Finally, since the fixing device is located on the inner wall of the feeding shell and faces the center of the screw, it does not occupy the space of the feeding shell for storing ingredients. When the user puts 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. In this way, the juicer's center of gravity is more stable when it is working and it is less prone to shaking. At the same time, the manufacturer can also set a larger feeding shell so that the user can put in more ingredients at once, which is more convenient for the user.

[0010] Preferably, the annular flange is made of metal, and the bottom of the juicing cup is provided with a wear-resistant metal part.

[0011] Preferably, the inner wall of the feed housing is provided with an upper limit platform extending towards the center of the screw. The upper limit platform is located above the screw, and 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 upward.

[0012] 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.

[0013] Preferably, the projection of the screw in the horizontal direction is located inside the projection of the upper feed channel in the horizontal direction.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] Preferably, the projection of the upper limit station in the horizontal direction does not intersect with the central axis of the screw.

[0018] Preferably, the fixing device and the upper limit are a tabletop integrated structure, with the fixing device protruding from the edge of the upper limit platform.

[0019] Preferably, the annular flange is a gear-shaped protrusion, and the outer edges of the protrusion are on the same circle centered on the screw.

[0020] Preferably, the screw has a positioning shaft at its center that runs through the entire screw, and the positioning shaft and the positioning protrusion are an integral structure.

[0021] Preferably, the thickness of the thickest part of the fixing device is 5 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 Figure Description

However, the following embodiments are only preferred embodiments of the present utility model and not all of them.

[0030] Figure 1-3 As shown, this embodiment includes a feeding housing 1 and an extrusion assembly 2. The extrusion assembly 2 includes a juicing cup 21 and a screw 22 disposed within the juicing cup 21. The bottom of the screw 22 is provided with an annular flange 221. The upper end face of the annular flange 221 abuts against the bottom of the juicing cup 21 to axially limit the screw 22. The top center of the screw 22 is also provided with a positioning protrusion 23. The feeding housing 1 is also provided with a fixing device 16. The fixing device 16 is provided with a limiting hole 17 that cooperates with the positioning protrusion 23. The positioning protrusion 23 is embedded in the limiting hole 17 to axially and circumferentially limit the screw 22.

[0031] This design offers several advantages. First, the screw 22 of this invention has an annular flange 221 at its bottom. This annular flange 221 forms a circumferential limit by abutting against the bottom of the juicing cup 21, preventing the screw 22 from moving upwards when squeezing fruits and vegetables. Simultaneously, the large contact area between the annular flange 221 and the bottom of the juicing cup 21 distributes the pressure on the annular flange 221, reducing pressure and making the product more durable and lowering the probability of damage. Second, this invention uses a positioning protrusion 23 at the top of the screw 22 and a fixing device 16 located inside the feed housing 1 for axial and circumferential limiting. This not only limits the vertical direction of the screw 22 but also... It can also prevent the screw 22 from shaking in the horizontal direction, improving the stability of the product during operation. Finally, since the fixing device 16 is located on the inner wall of the feeding shell 1 and is oriented towards the center of the screw 22, it does not occupy the space of the feeding shell 1 for storing ingredients. When the user puts 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. In this way, the juicer's center of gravity is more stable during operation and it is 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.

[0032] Since the annular flange 221 is prone to wear when the screw 22 rotates, the annular flange 221 in this embodiment is preferably made of metal. The bottom of the juicing cup 21 is preferably provided with a wear-resistant metal part 24. In this way, the wear between parts can be effectively reduced, and the situation that plastic may be mixed into the fruit and vegetable juice when plastic material is used is avoided, thus improving the hygiene and safety level.

[0033] In this embodiment, an upper limit platform 11 is preferably provided on the inner wall of the feed housing 1 extending toward the center of the screw 22. The upper limit platform 11 is located above the screw 22. 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. When the food is guided into the temporary squeezing space 3 by the screw 22 and squeezed, the upper limit platform 11 prevents the food from escaping upward.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] Figure 2 In the figure, S3 is the preferred horizontal projection of the upper limit platform 11, as shown in the figure. The horizontal projection S3 of the upper limit platform 11 does not intersect with the central axis of the screw 22. This arrangement ensures that the upper limit platform 11 can prevent food from escaping upwards while maximizing the cross-sectional area of ​​the lower feed channel 13, allowing the product to accommodate larger amounts of food into the temporary extrusion space 3. The fixing device 16 and the upper limit platform 11 are preferably an integrated structure. This design reduces the number of parts, improves aesthetics, and reduces internal gaps, grooves, and other structures that are difficult to clean.

[0043] See Figure 1 The fixing device 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 so that larger volumes of food can pass through.

[0044] like Figure 3 As shown, in this embodiment, the annular flange 221 is preferably a gear-shaped tooth, and the outer edge of the tooth is on the same circle centered on the screw 22. This arrangement is to allow the fruit and vegetable residue to be squeezed into the residue discharge channel while the screw 22 is rotating. In other embodiments, the juicer body can also adopt other residue discharge structures, so the annular flange 221 can also be set as a complete circular flange. These embodiments all fall within the protection scope of this utility model.

[0045] Preferably, the screw 22 has a positioning shaft that runs through the entire screw 22. The positioning shaft and the positioning protrusion 23 are an integral structure. In this embodiment, the positioning shaft is also connected to the motor output shaft in the juicer base, and at the same time plays the functions of transmission and axial positioning of the screw 22. Setting the positioning shaft and the positioning protrusion 23 as an integral structure can reduce the number of parts and reduce production costs.

[0046] 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 area 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-sectional area of ​​the lower feed channel 13 may be too small, and large-diameter food may not be able to enter.

[0047] 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.
