[0052] like Figure 1 and Figure 2 As shown, this application provides a pressing component 100, which is a hollow structure with openings at both ends. The pressing component 100 includes a main body 110 and a first pressing screw 120. The main body 110 has a pressing chamber 111, which extends from the top end of the main body 110 to the bottom end of the main body 110. The first pressing screw 120 is used to press the food to achieve juice extraction. The first pressing screw 120 is disposed at the top end of the main body 110 and extends toward the interior of the pressing chamber 111.

[0053] Compared to the traditional pressing method of setting a pressing spiral part on the side wall of the main body, this application sets a first pressing spiral part 120 extending into the pressing chamber 111 at the top of the main body 110. Since the first pressing spiral part 120 can generate a direct downward pressing force on the food, it can effectively improve the pressing efficiency and juice yield of the pressing component 100 and reduce food waste.

[0054] In one embodiment, the first pressing screw 120 extends into the pressing chamber 111. The first pressing screw 120 is arranged perpendicular to the axial direction of the main body 110, and the depth of the first pressing screw 120 extending into the pressing chamber 111 gradually increases from the center of the pressing chamber 111 to the side wall of the pressing chamber 111. Since the food needs to be pressed by the side wall of the pressing chamber 111 after being crushed by the cutting part at the top of the pressing chamber 111, the top side wall of the pressing chamber 111 needs to have sufficient pressure. Therefore, the depth of the first pressing screw 120 extending into the pressing chamber 111 near the side wall of the pressing chamber 111 needs to be deeper.

[0055] According to the relationship between action and reaction forces, the greater the pressing force of the first pressing spiral 120, the deeper the first pressing spiral 120 extends into the pressing chamber 111. Otherwise, the food will easily rotate and cannot be fed. Therefore, preferably, the maximum depth of the first pressing spiral 120 extending into the pressing chamber 111 is ≥2mm.

[0056] In one embodiment, the first pressing spiral 120 is serrated in order to better cut the ingredients into smaller pieces.

[0057] In one embodiment, to improve the pressing efficiency and juice yield of the further pressing component 100, the first pressing spiral portion 120 includes at least two spirals, which are evenly distributed at the top end of the main body portion 110. In this embodiment, the first pressing spiral portion 120 includes three spirals, which are evenly distributed at the top end of the main body portion 110. It is understood that in other embodiments, the number of first pressing spiral portions 120 can be one, two, three, or four or more, and is not limited to a single number.

[0058] In one embodiment, the inner diameter of the pressing chamber 111 gradually decreases from the top to the middle and gradually increases from the middle to the bottom. That is, the inner diameter of the pressing chamber 111 first decreases and then increases from top to bottom. Setting the inner diameter of the pressing chamber 111 to be larger at the top allows it to hold more ingredients, improving juicing efficiency. Simultaneously, setting the inner diameter of the pressing chamber 111 to be smaller in the middle and larger at the bottom facilitates the assembly of the pressing component 100 from top to bottom, thereby improving the assembly efficiency of the pressing component 100 with other components.

[0059] In one embodiment, the included angle between the first pressing screw section 120 and the axial section of the main body section 110 is ≤60°. This setting is to avoid affecting the material feeding due to an excessively large included angle between the first pressing screw section 120 and the axial section of the main body section 110. At the same time, the limitation of this included angle range can also increase the overall height of the pressing component 100.

[0060] In one embodiment, to avoid the cutting effect being affected by the short circumference of the first pressing spiral 120, the circumference of the first pressing spiral 120 is ≥10mm.

[0061] In one embodiment, the top of the pressing chamber 111 is provided with a feed inlet 112, which is connected to the pressing chamber 111. The food to be pressed can fall into the pressing chamber 111 through the feed inlet 112. The first pressing spiral part 120 is provided at the feed inlet 112.

[0062] In one embodiment, reference Figure 10In order to allow the feed inlet 112 to accept ingredients larger than the radius of the pressing chamber 111, the maximum size of the feed inlet 112 is greater than or equal to half the maximum size of the top of the main body 110.

[0063] like Figure 1 and Figure 2 As shown, in one embodiment, a central shaft 130 is provided at the top of the pressing chamber 111, and the central shaft 130 is disposed at the feed inlet 112 of the pressing chamber 111. A first pressing spiral portion 120 is connected between the central shaft 130 and the inner wall of the pressing chamber 111. Specifically, the depth of the first pressing spiral portion 120 extending into the pressing chamber 111 gradually increases from the central shaft 130 to the side wall of the pressing chamber 111, and a plurality of first pressing spiral portions 120 are evenly spaced along the circumference of the central shaft 130 on the outer side wall of the central shaft 130.

[0064] In one embodiment, the central shaft 130 includes a bearing seat 131 and a main shaft body 132 passing through the bearing seat 131. The bearing seat 131 and the main shaft body 132 are coaxially arranged, and the main shaft body 132 completely passes through the bearing seat 131. Both ends of the main shaft body 132 extend to the outside of the bearing seat 131. Specifically, the first pressing screw portion 120 is connected between the bearing seat 131 and the inner wall of the pressing chamber 111.

[0065] like Figure 3 and Figure 4 As shown, in one embodiment, to improve the pressing efficiency and juice yield of the further pressing component 100, a second pressing spiral portion 140 is provided on the side wall of the main body 110. The second pressing spiral portion 140 is used to press the food to achieve juice extraction. Further, the second pressing spiral portion 140 includes multiple pressing spiral strips 141 disposed on the outer side wall of the main body 110. A guide channel 142 is formed between two adjacent pressing spiral strips 141. The guide channel 142 extends spirally along the axial direction of the main body 110 so that the juice and residue formed after pressing the food can be smoothly discharged from the pressing component 100 along the guide channel 142.

[0066] like Figure 2 and Figure 4As shown, in one embodiment, a filter section 150 is provided on the side wall of the main body 110. The filter section 150 is used to filter the juice and residue produced after pressing the food in the pressing chamber 111, so as to separate the juice and residue. By providing the filter section 150 on the side wall of the main body 110, there is no need to install an additional filter device, which is convenient for installation, reduces the space occupied by the filter device, and thus reduces the product size and material cost. In an optional embodiment, the filter section 150 includes a plurality of filter screens 152 spaced apart on the side wall of the main body 110. Specifically, the filter screens 152 extend along the height direction of the pressing member 100, and the plurality of filter screens 152 are arranged circumferentially around the pressing member 100. In an optional embodiment, the filter section 150 includes a plurality of filter holes 154 spaced apart on the side wall of the main body 110. Specifically, the plurality of filter holes 154 are arranged circumferentially around the pressing member 100.

[0067] like Figure 5 As shown, in one embodiment, a cutting section 160 is provided at the top of the pressing member 100. Specifically, the cutting section 160 is provided at the top of the main body 110. In one embodiment, the cutting section 160 can be made of metal, such as iron or stainless steel. The cutting section 160 is used to pre-cut the food ingredients so that the first pressing spiral section 120 can further finely cut and grind the food ingredients, preventing the pressing member 100 from stopping abruptly due to the large volume of the food ingredients, thereby improving the juice yield and juicing efficiency of the pressing member 100. In one embodiment, the cutting section 160 is connected to the central shaft 130 of the pressing member 100. The two ends of the cutting section 160 are respectively provided with a cutting blade section 162 for cutting and a scraper section 164 for scraping. The height of the cutting blade section 162 is greater than the height of the scraper section 164. The cutting blade section 162 is set relatively high to facilitate cutting, and the scraper section 164 is set relatively low to facilitate scraping.

[0068] In one embodiment, the surface of the pressing member 100 is provided with a wear-resistant component to reduce the friction between the pressing member 100 and other adjacent components, thereby reducing wear on the pressing member 100 and other adjacent components and extending their service life. Optionally, the wear-resistant component may be made of materials such as plastic, metal, or ceramic.

[0069] like Figure 5 As shown, this application also provides a pressing assembly 101, which includes a pressing column 210 and the aforementioned pressing member 100. The pressing member 100 is rotatably sleeved on the outside of the pressing column 210 through a pressing chamber 111. A pressing gap 220 is formed between the pressing member 100 and the pressing column 210. The pressing column 210 is used to cooperate with the pressing member 100 to press the food in the pressing gap 220 to achieve juice extraction.

[0070] In one embodiment, the pressing assembly 101 further includes a pressing cup 200, with the pressing component 100 rotatably disposed within the pressing cup 200. A pressing column 210 is disposed within the pressing cup 200. Specifically, the pressing column 210 is located below the first pressing spiral portion 120. The pressing column 210 extends protruding from the bottom of the pressing cup 200 towards the top of the pressing cup 200. The pressing column 210 has a hollow structure with a closed top and an open bottom. The outer diameter of the pressing column 210 gradually increases from the top to the bottom. The pressing column 210 and the pressing cup 200 are coaxially arranged. The pressing column 210 and the pressing cup 200 can be integrally formed.

[0071] like Figure 6 As shown, the top of the pressing column 210 is tapered, and a through hole 211 is provided at the top of the pressing column 210. The through hole 211 is located at the center of the top of the pressing column 210. The through hole 211 is coaxially arranged with the pressing column 210. One end of the main shaft 132 of the central shaft 130 passes through the through hole 211 and extends into the pressing column 210.

[0072] In one embodiment, the top of the pressing column 210 is provided with a feeding rib 212 and / or a feeding groove 213. Both the feeding rib 212 and the feeding groove 213 are used to guide the food into the pressing gap 220. At the same time, the feeding rib 212 can provide resistance to the food. That is, when the pressing member 100 drives the food to rotate, the feeding rib 212 can block the food. The food is crushed by the cooperation between the pressing member 100 and the feeding rib 212, so as to further improve the juicing efficiency of the food.

[0073] Furthermore, there are multiple feeding ribs 212, which are spaced apart circumferentially at the top of the pressing column 210. A feeding groove 213 is formed between two adjacent feeding ribs 212, and both the feeding ribs 212 and the feeding groove 213 extend to the edge of the pressing column 210. In one embodiment, to ensure the feeding effect, the height of the highest point of the feeding rib 212 is ≥2mm. In one embodiment, to ensure the feeding effect, the depth of the deepest part of the feeding groove 213 is ≥2mm.

[0074] like Figure 5 As shown, in one embodiment, the pressing assembly 101 includes a feed hopper 300, which is mounted on the pressing cup 200; wherein, the pressing component 100 is rotatable relative to the feed hopper 300, the feed hopper 300 is used to hold food, and the internal space of the feed hopper 300 is connected to the internal space of the pressing cup 200.

[0075] In one embodiment, a limiting part 400 is provided between the pressing member 100 and the feeding barrel 300. The limiting part 400 is used to restrict the axial movement of the pressing member 100 relative to the feeding barrel 300, so as to ensure that the relative position positioning of the pressing member 100 and the feeding barrel 300 is reliable, thereby ensuring that the axial rotation operation of the pressing member 100 and the feeding barrel 300 is more stable.

[0076] like Figure 7 As shown, specifically, the limiting part 400 is fixed to the bottom end of the feeding barrel 300, and the pressing part 100 is limited between the limiting part 400 and the feeding barrel 300. The limiting part 400 can be fixed to the bottom end of the feeding barrel 300 by threaded fasteners. In one embodiment, a fixing post 310 is provided at the bottom end of the feeding barrel 300, the limiting part 400 is provided with an insertion hole 410, the fixing post 310 is inserted and fixed in the insertion hole 410, the limiting part 400 is provided with a first fixing hole 420 communicating with the insertion hole 410, the fixing post 310 is provided with a second fixing hole 311, and threaded fasteners pass through the first fixing hole 420 and the second fixing hole 311 in sequence to fix the fixing post 310 in the insertion hole 410.

[0077] Furthermore, the limiting part 400 is provided with a first step part 430, and the bottom end of the feeding barrel 300 is also provided with a second step part 320, which extends circumferentially along the feeding barrel 300. The pressing part 100 is provided with a third step part 160 circumferentially, which is limited between the first step part 430 and the second step part 320. Specifically, the third step part 160 is provided on the outer wall of the main body part 110 and extends circumferentially along the main body part 110.

[0078] like Figure 8 As shown, further, multiple connecting ribs 330 are provided at the connection between the feed barrel 300 and the pressing cup 200. The connecting ribs 330 can be spiral connecting ribs 330. The connecting ribs 330 are connected between the central shaft 130 and the inner wall of the feed barrel 300. Specifically, the end of the connecting rib 330 away from the feed barrel 300 is sleeved on the outer side of the main shaft body 132 of the central shaft 130 and supported on the bearing seat 131 of the central shaft 130.

[0079] like Figure 8As shown, in one embodiment, to improve juice extraction efficiency, a first juice outlet channel 201 is provided between the pressing member 100 and the pressing column 210. The first juice outlet channel 201 is located within the pressing gap 220. A second juice outlet channel 202 is provided between the pressing member 100 and the pressing cup 200. That is, the first juice outlet channel 201 is located within the pressing chamber 111 of the pressing member 100, and the second juice outlet channel 202 is located on the outside of the pressing member 100. Specifically, a filter section 150 (e.g., filter screen 152 or filter hole 154) is provided on the side wall of the pressing member 100. The first juice outlet channel 201 communicates with the second juice outlet channel 202 through the filter section 150, and the juice in the first juice outlet channel 201 can flow out through the filter section 150 into the second juice outlet channel 202.

[0080] like Figure 8 As shown, in one embodiment, a juice outlet 203 and a residue outlet 204 are provided on the side wall of the pressing cup 200. The juice outlet 203 and the residue outlet 204 are located on opposite sides of the pressing cup 200. Both the juice outlet 203 and the residue outlet 204 are connected to the pressing chamber 111. The juice in the pressing chamber 111 can be discharged to the outside through the juice outlet 203, and the residue in the pressing chamber 111 can be discharged to the outside through the residue outlet 204. Specifically, the first juice outlet channel 201 and the second juice outlet channel 202 are both connected to the juice outlet 203. The juice in the first juice outlet channel 201 and the juice in the second juice outlet channel 202 can both be discharged to the outside through the juice outlet 203 to improve the juice extraction efficiency.

[0081] like Figure 9 As shown, in one embodiment, a baffle 205 is provided at the top of the pressing member 100, and a cutting member 206 is provided at the top of the pressing column 210. The baffle 205 can rotate relative to the cutting member 206. The baffle 205 and the cutting member 206 cooperate to form a crushing mechanism. The baffle 205 can block the food to facilitate the cutting member 206 to crush the food. The crushing mechanism can shear the food, which is beneficial for cutting long food, especially long-fiber food, such as celery, ginger or wheatgrass. This can effectively shorten the food to facilitate the discharge of residue and extend the juicing time. At the same time, the shearing action of the crushing mechanism can also cut the food into smaller pieces and increase the juice yield.

[0082] In one embodiment, the middle part of the baffle 205 is connected to the central shaft 130, and the two ends of the baffle 205 are respectively connected to the opposite sides of the top of the main body 110. The cutter 206 is disposed on the side edge of the pressing column 210. The cutter 206 is formed by protruding upward from the top of the pressing column 210 and extends to the outside of the pressing chamber 111. The width of the cutter 206 gradually increases from the top of the cutter 206 to the bottom of the cutter 206 to enhance the bottom strength of the cutter 206. The baffle 205 has a clearance groove 207. The cutter 206 is located below the baffle 205 and is housed in the clearance groove 207 of the baffle 205. In one embodiment, in order to better extract juice while ensuring a reasonable clearance, the gap between the baffle 205 and the cutter 206 is 0-10mm.

[0083] refer to Figure 11 In one embodiment, the central shaft 130 extends beyond the pressing chamber 111, and extends away from the top of the pressing chamber 111. The height of the first pressing screw 120 gradually decreases from its first end to its second end. The first end of the first pressing screw 120 is the end connected to the central shaft 130, and the second end is the end connected to the side wall of the pressing chamber 111. This configuration creates a height difference between the first and second ends of the first pressing screw 120, allowing it to simultaneously perform lateral and longitudinal shearing (e.g., axial shearing of the pressing column 210) with the pressing column 210 (e.g., the cutting component 206) during rotation, thus facilitating finer cutting of the ingredients and increasing juice yield.

[0084] It is understandable that if the included angle α formed between the first pressing screw 120 and the central axis 130 is too small, or if the height difference H between the first end and the second end of the first pressing screw 120 is too small, the shearing effect will be affected. However, if the included angle α or the height difference H is too large, the overall volume of the pressing assembly 101 will be too large. In one embodiment, to ensure the shearing effect while avoiding an excessively large overall volume of the pressing assembly 101, the height difference H between the first end and the second end of the first pressing screw 120 is greater than 5 mm, and the included angle α formed between the first pressing screw 120 and the central axis 130 is... ＞ 15°.

[0085] like Figure 5 and Figure 9As shown, this application provides a juicer 10, which includes a power output component 500 and the aforementioned pressing component 101. The power output component 500 is pulsatorically connected to the pressing component 100 and is used to drive the pressing component 100 to rotate. Specifically, the pressing component 100 is rotatably disposed within the pressing cup 200, and the top end of the pressing component 100 has a central shaft 130; the power output component 500 has a drive shaft 510, which extends into the pressing cup 200 and is pulsatorically connected to the central shaft 130, and the drive shaft 510 is disposed adjacent to the central shaft 130.

[0086] In the juicer 10 described above, the power output component 500 can drive the pressing element 100 to rotate through the transmission connection between the drive shaft 510 and the central shaft 130, so that the pressing element 100 cooperates with the pressing cup 200 to press the ingredients put into the pressing cup 200 to achieve juicing. Since the drive shaft 510 extends into the pressing cup 200 and is set close to the central shaft 130 of the pressing element 100, the distance between the drive shaft 510 and the central shaft 130 is greatly reduced, resulting in higher transmission efficiency between the drive shaft 510 and the central shaft 130. This can effectively improve the operating stability of the pressing element 100 and thus ensure the pressing accuracy of the pressing element 100. At the same time, the drive shaft 510 being set close to the central shaft 130 of the pressing element 100 can also reduce the overall height of the juicer 10, improving the pressing performance, storage effect and portability of the juicer 10.

[0087] Specifically, the central shaft 130 is located in the axial direction of the pressing member 100, and the drive shaft 510 is partially inserted into the central shaft 130, with the drive shaft 510 and the central shaft 130 being coaxially arranged. In one embodiment, the drive shaft 510 extends into the pressing cup 200 to a depth greater than or equal to half the total height of the pressing cup 200. This arrangement allows the drive shaft 510 to be closer to the central shaft 130 of the pressing member 100, resulting in higher transmission efficiency between the drive shaft 510 and the central shaft 130, and more stable operation of the pressing member 100. In one embodiment, the drive shaft 510 extends into the pressing cup 200 to a depth greater than or equal to 25 mm. In one embodiment, the vertical distance between the top end of the drive shaft 510 and the top end of the pressing member 100 is less than or equal to 45 mm.

[0088] like Figure 5As shown, in one embodiment, the drive shaft 510 and the central shaft 130 are sleeved together, and the coupling length between the drive shaft 510 and the central shaft 130 is ≥5mm, so as to improve the connection stability between the drive shaft 510 and the central shaft 130. Specifically, the coupling point between the drive shaft 510 and the central shaft 130 in this application can be understood as the position where the drive shaft 510 and the central shaft 130 come into contact with each other during the operation of the juicer 10. When the two come into contact with each other, a coupling effect is formed. Specifically, in order to improve the connection stability between the drive shaft 510 and the central shaft 130, the drive shaft 510 and the central shaft 130 can be interlocked.

[0089] like Figure 9 As shown, in one embodiment, the pressing member 100 has a pressing chamber 111 inside, and at least a portion of the power output component 500 is housed within the pressing chamber 111. In one embodiment, the power output component 500 further includes a motor 520 and a reduction gear 530. The motor 520 is driven to the input end of the reduction gear 530, and the drive shaft 510 is driven to the output end of the reduction gear 530. By providing the reduction gear 530, the power output component 500 can achieve a speed reduction and torque increase effect, thereby increasing the pressing force of the pressing member 100 and improving the juicing effect of the juicer 10. Specifically, the reduction gear 530 and the drive shaft 510 are housed within the pressing chamber 111. Specifically, at least a portion of the power output component 500 is housed within the pressing column 210.

[0090] like Figure 9 As shown, the juicer 10 further includes a housing 600, a pressing cup 200 mounted on the housing 600, and at least a portion of the power output assembly 500 housed within the housing 600. Specifically, the motor 520 of the power output assembly 500 is disposed within the housing 600. Furthermore, the top of the housing 600 protrudes upward to form a boss 610, a portion of which extends into the pressing column 210. At least a portion of the power output assembly 500 is housed within the boss 610. Specifically, the reduction gear 530 of the power output assembly 500 is housed within the boss 610, and the drive shaft 510 of the power output assembly 500 passes through the boss 610 and is connected to the main shaft 132 of the central shaft 130.
