[0001] This application relates to the field of juicer technology, and more particularly to a pressing component and a juicer. Background Technology
[0002] A juicer is a machine that can quickly extract juice from fruits and vegetables. It can juice a variety of different kinds of fruits and vegetables and allows users to choose according to their preferences.
[0003] Existing juicers typically have a cutting blade inside the pressing barrel to pre-cut larger pieces of food into smaller volumes, which improves pressing efficiency when the pressing head is used for pressing. However, during the food cutting process, a lot of food debris adheres to the inner wall of the pressing barrel, resulting in a large amount of food residue, which affects the juice yield and user experience. Utility Model Content
[0004] Therefore, it is necessary to provide a pressing component and juicer that has a high juice yield and can avoid mechanical wear and tear on the pressing barrel.
[0005] A pressing assembly, comprising:
[0006] A pressing barrel, wherein the pressing barrel is provided with a pressing chamber inside;
[0007] The pressing head is rotatably disposed within the pressing chamber; and
[0008] A scraper is rotatably disposed within the pressing chamber and located between the pressing head and the inner wall of the pressing chamber. The scraper is elastic so that it can undergo elastic deformation when subjected to force.
[0009] In one embodiment, the scraper is disposed on top of the pressing head.
[0010] In one embodiment, the scraper includes a connecting portion and a scraping portion connected to the connecting portion, the connecting portion being connected to the top of the pressing head.
[0011] In one embodiment, the scraper blade is elastic as a whole, or the scraper blade is elastic in a portion.
[0012] In one embodiment, the scraper is made of soft rubber; and / or
[0013] The hardness of the scraper blade is ≤70 degrees; and / or
[0014] The initial deformation force of the scraper blade is ≤50N.
[0015] In one embodiment, the scraper is provided with a clearance area in the opposite direction of the rotation direction of the pressing head, and the scraper can deform toward the clearance area when subjected to force.
[0016] In one embodiment, the scraper blade tilts toward the clearance area in a natural state free from external force.
[0017] In one embodiment, the volume of the clearance area is ≥125mm. 3 .
[0018] In one embodiment, the maximum rotational diameter of the scraper is greater than the maximum diameter of the bottom of the pressing head.
[0019] In one embodiment, the maximum rotation diameter of the scraper is ≥65mm; and / or
[0020] The minimum gap between the scraper and the inner wall of the pressing chamber is ≤15mm.
[0021] In one embodiment, one end of the scraper is disposed on the pressing head, and the other end of the scraper is suspended and extends away from the pressing head.
[0022] In one embodiment, the scraper blade is capable of contacting the inner wall and bottom wall of the pressing chamber.
[0023] In one embodiment, the scraping height of the outer side wall of the scraper is ≥5mm.
[0024] In one embodiment, the scraper blades are provided with at least two.
[0025] In one embodiment, the scraper is provided with guide ribs or guide grooves in the scraping area of the pressing chamber.
[0026] In one embodiment, the pressing head includes a main body, a pressing spiral, and a cutting section. The pressing spiral is disposed on the outer side wall of the main body, the cutting section is disposed on the top of the main body, and the scraper is disposed on the top of the cutting section.
[0027] In one embodiment, the main body includes a crushing section and a pressing section connected sequentially from top to bottom. The crushing section has a crushing part on its outer side wall, the pressing section has a pressing spiral part on its outer side wall, and the crushing section has a cutting part at its top.
[0028] A pressing assembly, comprising:
[0029] Press barrel;
[0030] A pressing head is rotatably mounted inside the pressing barrel, and a pressing chamber is provided inside the pressing head; and
[0031] A scraper is disposed at the top of the pressing head, and the scraper is elastic so that it can undergo elastic deformation when subjected to force.

[0034] The aforementioned pressing assembly features a rotatable scraper blade positioned between the pressing head and the inner wall of the pressing chamber. This scraper blade, during rotation, removes food adhering to the pressing head and the inner wall of the pressing chamber, effectively preventing food residue and increasing juice yield. Furthermore, the scraper blade is elastic and deforms under pressure, allowing it to make more thorough contact with the food, effectively scraping it off. This is particularly beneficial in the corners of the pressing chamber, where traditional hard scraper blades cannot easily penetrate. The scraper blade in this design, due to its self-deformation capability, can reach in and move the food, resulting in less food residue and a higher juice yield. In addition, because the scraper blade is elastic, contact with the outer wall of the pressing head or the inner wall of the pressing chamber does not cause mechanical wear on the pressing head or pressing barrel, effectively ensuring the reliability of the pressing assembly.

[0044] like Figure 1 As shown, this application provides a pressing assembly, which includes a pressing barrel 100, a pressing head 200, and a scraper 300. The pressing barrel 100 has a pressing chamber 110 inside, which is used to hold food. The pressing head 200 is rotatably disposed in the pressing chamber 110 and is used to cooperate with the pressing barrel 100 to press the food to achieve juice extraction. The scraper 300 is rotatably disposed in the pressing chamber 110 and is located between the pressing head 200 and the inner wall of the pressing chamber 110. The scraper 300 is elastic so that it can undergo elastic deformation when subjected to force.
[0045] In the aforementioned pressing assembly, a rotatable scraper 300 is disposed between the pressing head 200 and the inner wall of the pressing chamber 110. When rotating, the scraper 300 scrapes away food adhering to the pressing head 200 and the inner wall of the pressing chamber 110, effectively preventing food residue and increasing juice yield. Furthermore, the scraper 300 is elastic and can deform under force, allowing it to make more thorough contact with the food, especially in the corners of the pressing chamber 110, to remove it. Traditional hard material scraper blades 300 cannot be easily inserted, but the scraper blade 300 of this solution, due to its self-deformation ability, can be inserted to move the food, resulting in less food residue in the pressing chamber 110 and a higher juice yield. In addition, because the scraper blade 300 is elastic, it will not cause mechanical wear to the pressing head 200 and the pressing barrel 100 when it comes into contact with the outer wall of the pressing head 200 or the inner wall of the pressing chamber 110, effectively ensuring the reliability of the pressing components.
[0046] It is understandable that the top of the pressing head 200 is in the cutting and crushing stage. Therefore, small pieces of material are easily generated at the top of the pressing head 200 and cannot enter the pressing stage, ultimately resulting in food residue. Thus, the most likely location for food residue is the top of the pressing head 200, or within a certain range above and below the top of the pressing head 200. Therefore, in one embodiment, to better solve the problem of food residue, a scraper 300 is positioned at the top of the pressing head 200, and the scraper 300 can rotate synchronously with the pressing head 200. Specifically, the scraper 300 can be positioned on the upper side of the top of the pressing head 200, or it can be positioned on the side of the top of the pressing head 200; no single limitation is made here.
[0047] like Figure 2 As shown, in one embodiment, one end of the scraper 300 is disposed on the pressing head 200, and the other end of the scraper 300 is suspended and extends in a direction away from the pressing head 200. The scraper 300 is disposed in the radial direction of the pressing head 200.
[0048] like Figure 2As shown, in one embodiment, the scraper 300 includes a connecting portion 310 and a scraping portion 320 connected to the connecting portion 310, with the connecting portion 310 connected to the top of the pressing head 200. In one embodiment, when the connecting portion 310 is connected to the upper top of the pressing head 200, an angle is formed between the connecting portion 310 and the scraping portion 320. Specifically, the connecting portion 310 is perpendicularly connected to the scraping portion 320, and the connecting portion 310 is formed by bending and extending from one side of the scraping portion 320. In another embodiment, when the connecting portion 310 is connected to the top side of the pressing head 200, the connecting portion 310 is parallel to the scraping portion 320, and the connecting portion 310 is formed by extending from one side of the scraping portion 320 along the length direction of the scraping portion 320. Optionally, the connecting portion 310 and the scraping portion 320 are integrally formed.
[0049] In one embodiment, the scraper 300 is elastic as a whole, or a portion of the scraper 300 (e.g., the scraping portion 320 of the scraper 300) is elastic.
[0050] In one embodiment, in order to better scrape the food off the inner wall of the pressing chamber 110, the outer contour of the scraper 300 that contacts the inner wall of the pressing chamber 110 matches the inner contour of the pressing chamber 110.
[0051] In an optional embodiment, the scraper blade 300 is made of a soft material, such as soft rubber. It is understood that if the scraper blade 300 is too hard, the press head 200 will be difficult to assemble, and the scraper blade 300 will easily generate noise and be easily damaged when in contact with the inner wall of the press chamber 110. If the scraper blade 300 is too soft, it will be difficult to achieve the best scraping effect. In an optional embodiment, the hardness of the scraper blade 300 is ≤70 degrees. Preferably, the hardness of the scraper blade 300 can be 35 degrees, 45 degrees, or 55 degrees.
[0052] Understandably, if the initial deformation force of the scraper blade 300 is too large, the pressing head 200 will be difficult to assemble. Furthermore, the scraper blade 300 is prone to noise and damage when in contact with the inner wall of the pressing chamber 110. Conversely, if the initial deformation force of the scraper blade 300 is too small, it will be difficult to achieve the optimal scraping effect. In an optional embodiment, the initial deformation force of the scraper blade 300 is ≤50N. Preferably, the initial deformation force of the scraper blade 300 can be 20N, 30N, or 45N.
[0053] In one embodiment, to improve the efficiency of scraping the food, at least two scraper blades 300 are provided. It is understood that in other embodiments, the number of scraper blades 300 may also be set to one. It should be noted that any pressing assembly including scraper blades 300 is within the scope of protection of this application.
[0054] like Figure 2 and Figure 3As shown, in one embodiment, the scraper 300 is provided with a clearance area 330 in the opposite direction of the rotation direction of the pressing head 200. The clearance area 330 is used to allow the scraper 300 to avoid obstruction, and the scraper 300 can deform towards the clearance area 330 when subjected to force. It is understood that during the operation of the pressing assembly, the food is driven by the pressing head 200, and some food does not move. When the scraper 300 touches the food, the pressing head 200 continues to rotate, and the scraper 300 will deform towards the clearance area 330 in the opposite direction of the rotation direction of the pressing head 200 under the reaction force of the food. Specifically, the scraper section 320 is provided with the clearance area 330.
[0055] It is understandable that the larger the clearance area 330, the larger the scraper blade 300 can be designed. This allows the scraper blade 300 to be closer to the inner wall of the pressing chamber 110, resulting in cleaner scraping and a better scraping effect. Simultaneously, because the scraper blade 300 is designed to be larger, the pressing chamber 110 can be designed to be correspondingly larger. This not only increases the feed inlet and capacity of the pressing chamber 110 but also improves the juicing efficiency of the pressing assembly. In one embodiment, the volume of the clearance area 330 is ≥125mm². 3 Preferably, the volume of the clearance area 330 can be 125 mm². 3 500mm 3 Or 1000mm 3 .
[0056] like Figure 4 As shown, in one embodiment, the scraper blade 300 is tilted towards the clearance area 330 in its natural state when not subjected to external force. Specifically, the scraper blade 300 is tilted in its natural state when not subjected to external force, which makes it easier to remove and insert the pressing head 200 relative to the pressing chamber 110. This can effectively prevent vertical interference when the pressing head 200 is removed or inserted. By tilting the scraper blade 300 towards a preset position, the scraper blade 300 can be smoothly deformed towards the clearance area 330 when subjected to external force.
[0057] In one embodiment, the maximum rotation diameter of the scraper 300 is greater than the maximum diameter of the bottom of the pressing head 200. This configuration allows for a larger sweeping area of the scraper 300, enabling multi-directional sweeping to thoroughly clean the entire pressing chamber 110. Simultaneously, the diameter of the pressing barrel 100 can be designed to be correspondingly larger, increasing its capacity and ensuring that the food is completely pressed without residue. Preferably, the maximum rotation diameter of the scraper 300 is ≥65mm.
[0058] In one embodiment, to thoroughly clean the entire pressing chamber 110, the scraper 300 can contact the inner and bottom walls of the pressing chamber 110. In another embodiment, to more effectively remove the food from the inner wall of the pressing chamber 110, the scraping height of the outer wall of the scraper 300 is ≥5mm. Preferably, the scraping height of the outer wall of the scraper 300 can be 5mm, 15mm, or 25mm.
[0059] In one embodiment, in order to ensure the scraping effect of the scraper 300, and to ensure that the scraper 300 can scrape more cleanly when it interferes with the inner wall of the pressing chamber 110, the minimum gap between the scraper 300 and the inner wall of the pressing chamber 110 is ≤15mm. Preferably, the minimum gap between the scraper 300 and the inner wall of the pressing chamber 110 is 5mm or 0mm (i.e., the scraper 300 and the inner wall of the pressing chamber 110 are in direct contact).
[0060] like Figure 1 As shown, in one embodiment, the scraper 300 is provided with guide ribs 120 or guide grooves 130 in the sweeping area within the pressing chamber 110. Specifically, the guide ribs 120 or guide grooves 130 located in the sweeping area of the scraper 300 within the pressing chamber 110 can cooperate with the scraper 300 to feed the material. When the scraper 300 scrapes the material into this area, the guide ribs 120 or guide grooves 130 can guide the material scraped off by the scraper 300 to the central area of the pressing chamber 110 for the pressing head 200 to cooperate with the pressing barrel 100 for pressing, thereby improving the juicing efficiency. In an optional embodiment, the guide ribs 120 can be spiral ribs, and there are multiple guide ribs 120. The multiple guide ribs 120 are arranged circumferentially at intervals on the inner wall of the pressing chamber 110, and a guide groove 130 is formed between two adjacent guide ribs 120.
[0061] like Figure 2 and Figure 3 As shown, in one embodiment, the pressing head 200 includes a main body 210, a pressing spiral 220, and a cutting part 230. The pressing spiral 220 is disposed on the outer side wall of the main body 210, and the cutting part 230 is disposed on the top of the main body 210. In one embodiment, the cutting part 230 can be made of metal, such as iron or stainless steel. The cutting part 230 is used to pre-cut the food. A scraper 300 is disposed on the top of the cutting part 230. Specifically, the scraper 300 can be disposed on the upper side or the side of the top of the cutting part 230.
[0062] By configuring a cutting section 230 for pre-cutting ingredients at the top of the main body 210, the ingredients are cut into small pieces, making the feeding of ingredients smoother and leaving less residue, so that the pressing screw section 220 can further finely cut and grind the ingredients, preventing the pressing head 200 from stopping abruptly due to the large volume of the ingredients, thereby improving the juice yield and juicing efficiency of the pressing head 200.
[0063] In one embodiment, the main body 210 includes a crushing section 211 and a pressing section 212 connected sequentially from top to bottom. A crushing part 240 is provided on the outer wall of the crushing section 211, and a pressing spiral part 220 is provided on the outer wall of the pressing section 212. A cutting part 230 is provided at the top of the crushing section 211. The crushing section 211 is used for the initial crushing of the food, ensuring that as the food spirals downwards, only crushing action occurs, preventing the pressing head 200 from stopping abruptly due to excessive food volume. The pressing section 212 is used for further fine pressing of the food. This embodiment separates the crushing process from the juice extraction and residue removal process. During the crushing process, since juice extraction and residue removal are not required, there is no need to install filters or rotating brushes inside the pressing barrel 100. This allows the food inside the pressing barrel 100 to be crushed under the combined action of the pressing barrel 100 and the pressing head 200.
[0064] Furthermore, the cutting section 230 at the top of the crushing section 211 can pre-cut the food before it enters the crushing section 211, allowing larger pieces of food to be cut into smaller volumes, thus improving crushing efficiency when the crushing section 240 crushes the food. Specifically, the crushing section 240 is located below and adjacent to the cutting section 230. Since most of the food will fall automatically due to gravity after being pre-cut by the cutting section 230, the placement and proximity of the crushing section 240 to the cutting section 230 effectively improves crushing efficiency, thereby improving juicing efficiency and juice yield.
[0065] In one embodiment, the cross-sectional area of the main body 210 gradually increases from the crushing section 211 to the pressing section 212, that is, the main body 210 is generally conical. With the above arrangement, when the pressing head 200 is used in the pressing assembly to crush the food, the food can be crushed more and more, thereby improving the crushing effect of the pressing assembly on the food and increasing the juice yield.
[0066] like Figure 5 As shown, in another embodiment, this application also provides a pressing assembly, which includes a pressing barrel 100, a pressing head 200 and a scraper 300. The pressing head 200 is rotatably disposed inside the pressing barrel 100, and a pressing chamber 110 is provided inside the pressing head 200. The scraper 300 is disposed at the top end of the pressing head 200 and has elasticity so that it can produce elastic deformation when subjected to force.
[0067] The aforementioned pressing assembly, by configuring a scraper 300 at the top of the pressing head 200, can scrape off the food adhering to the inner wall of the pressing barrel 100 during rotation, thereby effectively avoiding food residue and increasing the juice yield. Moreover, the scraper 300 is elastic and can undergo elastic deformation under force, allowing it to make fuller contact with the food to scrape it off, especially in the corners inside the pressing barrel 100. Traditional hard scrapers 300 cannot easily penetrate these corners, but the scraper 300 in this design, due to its self-deformation ability, can penetrate and move the food, resulting in less food residue inside the pressing barrel 100 and a higher juice yield. On the other hand, because the scraper 300 is elastic, it will not cause mechanical wear to the pressing barrel 100 when it comes into contact with the inner wall, effectively ensuring the reliability of the pressing assembly. In one embodiment, a central shaft 101 is provided at the top of the pressing chamber 110, and a scraper 300 is connected to the central shaft 101 of the pressing head 200. The end of the scraper 300 away from the central shaft 101 has a scraping part 320, which is elastic.
[0068] like Figure 1 As shown, in one embodiment, this application also provides a juicer that includes the above-described pressing component.
[0069] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
