Description

Technical Field

[0001] The present invention relates to the technical field of juicers, and in particular to a rotation control method of a juicer with an automatic forward and reverse rotation control mode. Background Art

[0002] The juicer is also called a screw squeeze juicer. Its core component is a spiral squeezing screw. When the block food is sent into the cylindrical filter, the squeezing screw and the filter rotate relative to each other. The food is cut and squeezed out of the juice under the shearing action between the screw and the filter wall. The squeezed juice flows out through the filter holes.

[0003] When squeezing food, the juicer head of a traditional juicer relies solely on the rotation of the screw and the squeezing action of the filter wall to achieve cutting and squeezing, resulting in low cutting efficiency. Moreover, during the juicing process, food fibers tend to accumulate in the gap between two adjacent spiral ribs, causing the juicer head to get stuck, affecting the normal operation of the juicer. In order to solve the problem of the juicer head getting stuck, traditional juicers usually use a detection module to detect whether the juicer head is stuck by a blockage. When a blockage is stuck, the juicer head is controlled to reverse to loosen and fall. Obviously, this method can only be used to remedy the blockage after it has occurred, and cannot prevent the occurrence of a blockage. Moreover, since the juicer head is already stuck at this time, it may not be possible to reverse it. Summary of the Invention

[0004] The present invention provides a rotation control method of a juicer with an automatic forward and reverse rotation control mode, aiming to prevent the occurrence of blockage of a juicer head of the juicer.

The juicer head is controlled to rotate forward according to the second forward rotation frequency in the forward rotation period, and the juicer head is controlled to reverse according to the second reverse frequency in the reverse rotation period.

[0010] In one embodiment, the automatic forward and reverse control mode includes a first forward and reverse control mode and a second forward and reverse control mode; If the control mode is the first forward-reverse control mode, within the total set time, the driving mechanism first controls the juicer head to rotate forward according to the forward rotation set time, then controls the juicer head to rotate reversely according to the reverse rotation set time, and controls the juicer head to rotate forward and reverse alternately according to the forward rotation set time and the reverse rotation set time; If the control mode is the second forward and reverse control mode, within the total set time, the driving mechanism first controls the juicer head to reverse according to the reverse set time, and then controls the juicer head to forward according to the forward set time, and controls the juicer head to reverse and forward alternately according to the reverse set time and the forward set time.

[0011] In one embodiment, the control system includes a first button corresponding to the first forward and reverse control mode and a second button corresponding to the second forward and reverse control mode, and the first button and the second button are arranged on the surface of the juicer; the control system determines that the automatic forward and reverse control mode is the first forward and reverse control mode through the first button, and determines that the automatic forward and reverse control mode is the second forward and reverse control mode through the second button.

[0012] In one embodiment, the first button and the second button are physical buttons or touch screen buttons provided on the surface of the juicer.

[0013] In one embodiment, the control mode also includes a full forward control mode and a full reverse control mode. If the control mode is the full forward control mode, the juicer head is controlled by the driving mechanism to rotate forward; if the control mode is the full reverse control mode, the juicer head is controlled by the driving mechanism to rotate reversely.

[0015] In the juicer used in this control method, the juicer head includes a rod body and spiral ribs spirally arranged on the circumferential surface of the rod body. The spiral ribs spiral clockwise or counterclockwise around the rod body, and a spiral groove is formed between two adjacent spiral ribs. To prevent the juicer head from clogging, the technical solution of the present invention provides a toothed structure connected to the rod body within the spiral groove. Specifically, the toothed structure includes a toothed plate connected to the rod body and teeth arranged on the outer edge of the toothed plate. The teeth in the toothed structure can cut the food like a knife edge, so that the food can be broken down more quickly after entering the filter, thereby improving the juicing efficiency. In addition, the toothed structure can comb the food fibers like a comb during rotation. This combing action not only pushes the food fibers out of the spiral groove, but also redistributes the food fibers into the gap between the juicer head and the filter for further squeezing. It can effectively prevent the accumulation of food fibers in the spiral groove and ensure the continuity of the juicing process. Unlike traditional juicers, which typically reverse rotation after a blockage occurs, the juicer in this technical solution alternates between forward and reverse rotation according to a set program. This means that even if the juicer head isn't blocked, it will intermittently reverse at set intervals, proactively preventing blockages rather than passively waiting for a blockage to occur before remediating it. In summary, the present invention effectively prevents blockages through the combing action of the juicer head's toothed structure and its alternating forward and reverse rotation.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0022] In order to prevent the occurrence of clogging of a juicer head of a juicer, the present invention provides a rotation control method of a juicer with an automatic forward and reverse rotation control mode.

[0023] The present invention provides a method for controlling the rotation of a juicer with automatic forward and reverse rotation control modes, which is used to control the rotation of a juicer head. The juicer head includes a rod 1 and spiral ribs 2 spirally arranged on the lateral surface of the rod 1. A spiral groove is formed between adjacent spiral ribs 2, and a toothed structure 3 connected to the rod 1 is provided within the spiral groove. The juicer also includes a drive mechanism and a control system. The drive mechanism is in transmission connection with the juicer head, and the control system is electrically connected to the drive mechanism.

[0024] Reference Figure 6 , the control method provided by the present invention comprises the following steps: Get the control mode of the juicer head; If the control mode is the automatic forward and reverse control mode, the total set time, the forward set time and the reverse set time of the juicer are obtained; Within the total set time, the driving mechanism drives the juice extraction head to rotate forward and reverse alternately according to the forward rotation set time and the reverse rotation set time.

[0025] This technical solution improves the structure of the juicer head of the juicer, referring to Figure 1 The juicer head includes a rod body 1 and a spiral rib 2 spirally arranged on the circumferential surface of the rod body 1. The spiral rib 2 spirals clockwise or counterclockwise around the rod body 1, and a spiral groove is formed between two adjacent spiral ribs 2. In order to prevent the juicer head from being blocked, the technical solution of the present invention is provided with a tooth-like structure 3 connected to the rod body 1 in the spiral groove. Figures 2 to 5 The tooth structure 3 includes a tooth plate 31 connected to the rod body 1 and teeth 32 located on the outer edge of the tooth plate 31 (away from the rod body 1). The teeth 32 in the tooth structure 3 act like a knife blade to cut the food, allowing it to be broken down more quickly after entering the filter, thereby improving juicing efficiency. Furthermore, the tooth structure 3 acts like a comb as it rotates. This combing action not only pushes the food fibers out of the spiral groove but also redistributes them into the gap between the juicing head and the filter for further juicing. This effectively prevents the accumulation of food fibers within the spiral groove and ensures the continuity of the juicing process. Conventional juicers typically reverse rotation after a blockage occurs. In contrast, the juicer in this technical solution alternates between forward and reverse rotation according to a pre-set program. That is, even if the juicing head is not blocked, it will intermittently reverse at a set time. This proactively prevents blockages, rather than passively waiting for a blockage to occur before remedying it. In summary, the technical solution of the present invention can effectively prevent the occurrence of blockage through the combing effect of the tooth structure 3 of the juicer head and the rotation mode of the juicer head in alternating forward and reverse rotations.

[0026] It should be noted that the juicer may further include a filter, a feed bin, and a juice bin disposed below the feed bin. The feed bin is provided with an openable cover at the top, a feed port is provided at the bottom, and a receiving port is provided at the top of the juice bin opposite the feed port. The filter is disposed within the juice bin and covers the receiving port. The juicer head is at least partially disposed within the filter, and the juicer head, filter, and juice bin may be coaxially disposed. A drive mechanism for driving the juicer head to rotate is disposed within the feed bin or juice bin. The drive mechanism may be a DC motor or a stepper motor. The rotating shaft of the DC motor or stepper motor is in transmission connection with the rod body 1, thereby driving the juicer head to rotate.

[0027] The control system includes a main control board, which is arranged in the body of the juicer and electrically connected to the drive mechanism. The main control board has different control modes, such as automatic forward and reverse control mode, full forward control mode and full reverse control mode. When working, the main control board controls the forward and reverse rotation of the drive mechanism according to the preset program corresponding to the selected mode, thereby driving the juicer head to rotate forward and reverse.

[0028] The working process of the control system is as follows: after the power of the juicer is started, the control system obtains the control mode of the juicer head. If the control mode is the automatic forward and reverse control mode, the total set working time of the juicer, the forward set time and the reverse set time are obtained. Then, within the total set time, the driving mechanism drives the juicer head to rotate forward and reverse alternately according to the forward set time and the reverse set time.

[0029] It should be noted that the total set duration of the juicer's operation is the total set duration of the juicer head's rotation. The total set duration refers to the time the juicer head takes from the start of rotation to the stop of rotation, that is, the time required to complete a single juicing task. The forward setting duration refers to the duration of each forward rotation of the juicer head within the total set duration, which indicates the duration of a single forward rotation, rather than the sum of all forward rotation times. The reverse setting duration refers to the duration of each reverse rotation of the juicer head within the total set duration, which indicates the duration of a single reversal, rather than the sum of all reversal times. When the number of forward rotations and the number of reverse rotations are the same, the total set duration is an integer multiple of the sum of the forward setting duration and the reverse setting duration. Of course, in actual operation, the number of forward rotations and the number of reverse rotations may be different, and the specific situation shall prevail.

[0030] For example, if the juicer head is in automatic forward and reverse control mode, with a total set time of 180 seconds, a forward setting time of 50 seconds, and a reverse setting time of 10 seconds, the specific rotation process is as follows: 1-50 seconds, the juicer head rotates forward; 50-60 seconds, the juicer head rotates reversely; 61-110 seconds, the juicer head rotates forward; 110-120 seconds, the juicer head rotates reversely; 120-170 seconds, the juicer head rotates forward; 170-180 seconds, the juicer head rotates reversely. Within the total set time, the juicer head rotates forward three times and reverses three times.

[0031] When the juicer head rotates forward, the spiral ribs 2 and tooth-like structure 3 on the surface of the rod body 1 will push the food in the spiral direction to the squeezing area between the juicer head and the filter, thereby fully cutting and squeezing the food. In order to ensure that the food is fully squeezed, the forward rotation time needs to be long enough. When the juicer head reverses, the spiral ribs 2 and tooth-like structure 3 on the surface of the rod body 1 will push the food upward, which helps to redistribute the food fibers accumulated in the spiral groove to prevent blockage. However, a reversal time that is too long may cause the food to be redistributed to the spiral groove, so the reversal time is relatively short. Therefore, in actual operation, the forward setting time is usually longer than the reverse setting time, so as to achieve a balance between efficiency and anti-blocking.

[0032] The tooth structure 3 is arranged spirally along the spiral groove, which enables the tooth structure 3 and the spiral ribs 2 to work together during the juicing process, forming a continuous cutting and conveying path. Specifically, the tooth structure 3 and the spiral ribs 2 can spiral together clockwise or counterclockwise. During the rotation process, the teeth 32 of the tooth structure 3 can chop larger pieces of food into smaller particles. Some of these particles are directly pushed to the inner wall of the filter screen for squeezing by the tooth structure 3, while some are combed by the tooth structure 3 and enter the conveying channel between the tooth structure 3 and the spiral ribs 2. Then, under the dual action of the tooth structure 3 and the spiral ribs 2, they are pushed to the inner wall of the filter screen for squeezing, ensuring the continuity of the juicing process.

[0033] It should be noted that the toothed structure 3 can be a continuous spiral setting, that is, the toothed structure 3 spirally extends from one end of the rod body 1 to the other end, forming a complete spiral shape. The continuous spiral structure can ensure that the toothed structure 3 is evenly distributed throughout the spiral groove, providing consistent cutting and combing effects. Alternatively, the toothed structure 3 can be a discontinuous spiral setting, that is, it is composed of multiple independent spiral segments, and these spiral segments can be distributed at equal intervals or at unequal intervals. The discontinuous toothed structure 3 can provide more flexible cutting and combing effects. For example, a denser spiral segment can be set near the feed port to improve cutting efficiency; and a sparser spiral segment can be set near the discharge port to reduce fiber accumulation.

[0034] It is easy to understand that if the height of the tooth structure 3 protruding from the rod body 1 exceeds the height of the spiral ridges 2 protruding from the rod body 1, the food may fall directly downward after being cut by the tooth structure 3 and cannot be squeezed by the spiral ridges 2, resulting in insufficient extraction of the juice in the food. Therefore, in the embodiment of the present technical solution, the height of the tooth structure 3 protruding from the rod body 1 is less than or equal to the height of the spiral ridges 2 protruding from the rod body 1, thereby ensuring that the food can be smoothly transported by the spiral ridges 2 to the inner wall of the filter screen for squeezing after being cut.

[0035] The height of the toothed structure 3 protruding from the rod body 1 is defined as the tooth height of the toothed structure 3, and the toothed structure 3 has a first end facing the feed port and a second end away from the feed port. In some embodiments, the tooth height at the first end may be greater than the tooth height at the second end. For example, the tooth height at the first end may gradually decrease from the first end to the second end, that is, the tooth height gradually decreases from the first end to the second end, forming a continuous gradient. Alternatively, the tooth height at the first end is a first fixed value, the tooth height at the second end is a second fixed value, and the first fixed value is greater than the second fixed value. The higher the tooth height, the greater the depth to which the teeth 32 can cut into the food, and the stronger the cutting ability. The tooth height at the first end is relatively high, which can provide stronger cutting ability and quickly crush the food; the tooth height at the second end is relatively low, which can avoid excessive cutting of the food and damage to the fibers.

[0036] It should be noted that the first end and the second end can each occupy 50% of the total length of the tooth structure 3, or the first end can occupy the first 30% or 40% of the total length of the tooth structure 3, and the second end can occupy the remaining proportion of the total length of the tooth structure 3.

[0037] In some embodiments, the tooth structure 3 includes several spiral segments, each with a different tooth height. For example, the tooth structure 3 may include three spiral segments, which can be arranged continuously or intermittently. The first segment has a higher tooth height, providing stronger cutting power and quickly crushing the food. The second segment has a lower tooth height, primarily used to comb the fibers and reduce fiber accumulation. The third segment has a lower tooth height again, used to further refine the particles and facilitate the discharge of the pomace. The first, second, and third spiral segments can be arranged sequentially along the spiral direction, ensuring that the food is first quickly crushed after entering the juicer, followed by the combing of the fibers, and finally the discharge of the pomace. Alternatively, the first, second, and third spiral segments can be arranged freely, such as the first spiral segment can be arranged between the second and third spiral segments, thereby providing a more flexible processing sequence. Of course, in actual applications, there can be two or more spiral segments, and this is not a limitation.

[0038] In the embodiment of the present technical solution, the teeth 32 in the tooth structure 3 may be saw teeth, such as Figures 2 to 4The teeth are usually triangular or saw-like in shape, with sharp edges and sloped surfaces, which can provide strong cutting ability and are suitable for processing hard or coarse-fiber ingredients such as carrots, apples, and sugarcane.

[0039] Alternatively, the teeth 32 in the tooth structure 3 may be flat teeth, such as Figure 5 Flat teeth typically have a flatter cutting surface with smoother edges and no sharp points. Flat teeth have a relatively weaker cutting ability and are suitable for softer or finer-textured ingredients like watermelon, strawberries, and bananas.

[0040] The tooth plate 31 spirally wraps around the circumferential surface of the rod body 1 and is integrally connected to the rod body 1. The outer edge of the tooth plate 31 is provided with teeth 32. The tooth plate 31 has a first end facing the feed inlet and a second end away from the feed inlet. In some embodiments, the density of the teeth 32 at the first end can be greater than that at the second end, that is, the density of the teeth 32 increases gradually along the spiral direction. Figure 3 and Figure 4 The following are schematic diagrams of the tooth-like structure 3 after it is unfolded in one embodiment, where the left end is the first end and the right end is the second end. Specifically, the first end is close to the feed inlet. After the food enters the filter, it first contacts the densely arranged teeth 32. These densely packed teeth 32 can quickly chop the food into smaller particles, reducing food accumulation and clogging at the feed inlet, ensuring that the food can quickly enter the filter for juicing. The teeth 32 at the second end have a lower density, which can provide a larger channel for the pomace, allowing it to be discharged more smoothly, reducing the time the pomace stays on the juicing head, reducing the risk of clogging, and ensuring the continuity of the juicing process.

[0041] exist Figure 3 In the illustrated embodiment, the density of the teeth 32 gradually decreases from the first end to the second end. Specifically, the density of the teeth 32 decreases gradually from the first end to the second end, forming a continuous gradient along the length of the tooth plate 31. This gradual decrease in the density of the teeth 32 achieves a smooth transition from high to low density, avoiding sudden changes in the density of the teeth 32 and ensuring a smoother juicing process.

[0042] exist Figure 4In the illustrated embodiment, the teeth 32 at the first end and the teeth 32 at the second end are evenly arranged, and the density of the teeth 32 at the first end is greater than the density of the teeth 32 at the second end. It should be noted that the first end and the second end can each occupy 50% of the total length of the tooth plate 31, or the first end can occupy the first 30% or 40% of the total length of the tooth plate 31, and the second end occupies the remaining proportion of the total length of the tooth plate 31. In this embodiment, the density of the teeth 32 at the first end is a fixed value, and the density of the teeth 32 at the second end is another fixed value, and the density of the first end is greater than the density of the second end. This design divides the tooth plate 31 into two functional areas, the first end is responsible for efficient cutting, and the second end is responsible for cutting the remaining particles and discharging the pomace.

[0043] In some embodiments of the present invention, the teeth 32 at the first end can be sharper than the teeth 32 at the second end. For example, the teeth 32 at the first end can be serrated or triangular, with sharp edges and a larger cutting angle, while the teeth 32 at the second end can be flat or slightly serrated, with a smaller cutting angle. The teeth 32 at the first end, which is closer to the feed inlet, are designed to be sharper, providing stronger cutting power, enabling them to quickly cut into the food, breaking it into smaller particles, and reducing the accumulation of food at the feed inlet. The teeth 32 at the second end, which is farther away from the feed inlet, are designed to be relatively smooth or blunt, to avoid excessive cutting of the food and damage to the fibers.

[0044] To further improve juicing efficiency and prevent fiber accumulation, some embodiments of the present invention include at least two tooth structures 3 between two adjacent spiral ridges 2. Two or more tooth structures 3 increase the number of cutting points, subjecting food to more cutting action upon entering the filter, thereby more quickly breaking it into smaller particles. The multiple layers of tooth structures 3 act like a comb during rotation, combing the food fibers and further preventing fiber accumulation in the spiral grooves.

[0045] Furthermore, the teeth 32 of two adjacent tooth structures 3 can be staggered, with gaps between the teeth 32 of two adjacent tooth structures 3. This staggered arrangement of teeth 32 allows the ingredients to be cut from different angles, resulting in more comprehensive fragmentation and reduced food residue in certain directions, thereby improving cutting efficiency. Furthermore, the staggered arrangement of teeth 32 can disperse cutting forces to a certain extent, preventing excessively concentrated cutting forces from creating significant resistance in the food, thus making the juicing process smoother.

[0046] In this technical solution, the rod body 1, spiral ribs 2, and tooth structure 3 are integrally formed, meaning the entire juicing head structure is manufactured using a one-piece molding process. This one-piece molding eliminates joints and seams between components, allowing the rod body 1, spiral ribs 2, and tooth structure 3 to form a solid, integrated whole. This not only improves the structural strength of the juicing head but also prevents structural failure caused by loose or broken joints, helping to extend the life of the juicing head and ensure the stability and reliability of the juicing process.

[0047] The rod body 1, spiral ribs 2, and tooth structure 3 can be made of metal, such as steel, iron, stainless steel, aluminum alloy, titanium alloy, etc. Metal has high hardness and good wear resistance, can withstand heavy loads and frequent use, and is suitable for processing food of various textures. Alternatively, the rod body 1, spiral ribs 2, and tooth structure 3 can be made of ceramic. Ceramics also have extremely high hardness and wear resistance, can maintain a sharp cutting edge for a long time, and are suitable for cutting and pressing food.

[0048] The present invention also provides a juicer, which includes a shell, a filter and a juicer head structure. The specific structure of the juicer head structure refers to the above-mentioned embodiment. Since this juicer adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0049] The filter is disposed within a chamber of the housing, and the juicing head structure is at least partially rotatably disposed within the filter. Specifically, the housing may include a feed bin and a juice bin disposed below the feed bin. The feed bin has an openable cover at the top, a feed opening at the bottom, and a receiving opening at the top of the juice bin, located opposite the feed opening. The filter is disposed within the juice bin and covers the receiving opening. The juicing head structure is at least partially rotatably disposed within the filter. The juicing head, filter, and juice bin may be coaxially arranged. A drive mechanism for rotating the juicing head structure is disposed within the feed bin or the juice bin. For example, the drive mechanism may be a DC motor or a stepper motor. The drive mechanism is in transmission connection with the juicing head for driving the rotation of the juicing head. A cutting tool may be disposed within the feed bin and in transmission connection with the juicing head so that the tool rotates with the juicing head. The function of the cutting tool is to initially cut the food entering the feed bin, slicing large chunks into smaller pieces, thereby reducing the subsequent cutting burden on the juicing head. After the block food is placed in the feed bin, it is initially cut by the knife and then falls into the filter through the feeding port and the receiving port. The juice is then squeezed out under the relative rotation of the filter and the juicer head. The squeezed juice falls into the juice bin through the filter holes for collection, and the pomace is retained in the filter for easy cleaning.

[0050] The juice bin may be provided with a handle for easy gripping and a mouth for facilitating juice flow, thereby making it convenient for the user to pick up the juice bin and pour the juice into a cup or other container. The feed bin and the juice bin may be detachably connected, such as by a threaded connection or a snap connection, so that the feed bin and the juice bin can be separated from each other. After juicing is completed, the user can easily remove the feed bin and use the juice bin alone. This can prevent the entire juicer from being too heavy and reduce the burden on the user when pouring the juice.

[0051] It is not difficult to understand that the driving mechanism will inevitably generate noise during operation, and the juicing head structure will inevitably generate noise during the process of cutting and squeezing ingredients, thereby affecting the user experience. In order to alleviate the noise problem of the juicer, some embodiments of the juicer may be coated with a sound insulation layer on the inner wall and / or outer wall of the outer shell. Specifically, the sound insulation layer may be, but is not limited to, sound-absorbing sponge, sound-absorbing foam and sound insulation felt. These materials have a porous structure and can effectively absorb sound waves and alleviate the propagation of noise. The sound insulation layer can be pasted and coated on the inner wall of the outer shell, or it can be pasted and coated on the outer wall of the outer shell, or it can be provided as a sound insulation sleeve on the outer wall of the outer shell.

[0052] In some embodiments, a layer may be provided between the inner wall and the outer wall of the shell, and the layer may be filled with sound insulation material. The sound insulation material may be a sound-absorbing material such as sound-absorbing sponge or sound-absorbing foam, thereby achieving a sound insulation effect.

[0053] The control method of the present invention allows users to customize the total set time, the forward rotation set time, and the reverse rotation set time. In one embodiment, the control system includes a main control board and a control panel. The main control board is located on the body of the juicer and electrically connected to the drive mechanism. The control panel is located on the surface of the juicer and electrically connected to the main control board. The control panel includes a total time setting module, a forward rotation time setting module, and a reverse rotation time setting module.

[0054] At this time, refer to Figure 7 If the control mode is the automatic forward and reverse control mode, the control method further includes the following steps: The total set working time of the juicer is obtained through the total time setting module, the forward set working time of the juicer is obtained through the forward time setting module, and the reverse set working time of the juicer is obtained through the reverse time setting module.

[0055] At this time, the specific working process of the control system is as follows: after the juicer power is started, the control system obtains the control mode of the juicer head. If the control mode is the automatic forward and reverse control mode, the total set working time of the juicer is obtained through the total time setting module of the control panel, the forward set working time of the juicer is obtained through the forward time setting module of the control panel, and the reverse set working time of the juicer is obtained through the reverse time setting module of the control panel. Then, within the total set time, the juicer head is driven by the driving mechanism to rotate forward and reverse alternately according to the forward set time and the reverse set time.

[0056] The control panel is located on the surface of the juicer. Its interactive interface features modules for setting the total duration, forward rotation duration, and reverse rotation duration, allowing users to intuitively set parameters. The main control board is located within the juicer and electrically connected to the drive mechanism. The control panel and main control board are electrically connected to each other, enabling signal transmission. This allows the user-set parameters to be transmitted to the main control board, thereby precisely controlling the rotation of the juicer head.

[0057] This embodiment allows users to customize the total set time, forward set time, and reverse set time through the control panel. Users can flexibly adjust the time parameters of the juicing process based on the characteristics of different ingredients and juicing needs. For example, for ingredients with high fiber content, the reverse set time can be appropriately increased to enhance the anti-clogging effect; for ingredients that easily release juice, the total set time can be reduced to complete the juicing process faster, thereby improving the flexibility of the juicer.

[0058] In another embodiment, the control system pre-sets selectable total set time, forward rotation set time, and reverse rotation set time. In this case, the control system includes a main control board and a current detection device. The main control board is located within the juicer body and electrically connected to the drive mechanism. The current detection device is connected in series with the drive mechanism's circuitry and electrically connected to the main control board. The current detection device monitors the real-time current flowing through the drive mechanism and transmits the monitored real-time current to the main control board. The main control board then automatically selects the total set time, forward rotation set time, and reverse rotation set time based on the real-time current feedback.

[0059] At this time, refer to Figure 8 , the control method further comprises the following steps: A matching first total duration, a first forward rotation duration, and a first reverse rotation duration are preset, as well as a matching second total duration, a second forward rotation duration, and a second reverse rotation duration, wherein the second reverse rotation duration is greater than the first reverse rotation duration; If the control mode is the automatic forward and reverse control mode, the real-time current flowing through the drive mechanism is obtained by the current detection device; If the real-time current is within the preset current range, the total set duration of the juicer operation is determined to be the first total duration, the forward set duration of the juicer operation is determined to be the first forward duration, and the reverse set duration of the juicer operation is determined to be the first reverse duration; If the real-time current is outside the preset current range, the total set working time of the juicer is determined to be the second total working time, the forward setting working time of the juicer is determined to be the second forward time, and the reverse setting working time of the juicer is determined to be the second reverse time.

[0060] In this embodiment, the juicer control system is provided with a first working gear and a second working gear, wherein the first total time, the first forward time and the first reverse time correspond to the first working gear, and the second total time, the second forward time and the second reverse time correspond to the second working gear. When the texture of the food is soft or the fibers are fine, the first working gear can be selected for operation; when the texture of the food is hard or the fibers are coarse, the second working gear can be selected for operation. When the texture of the food is hard or the fibers are coarse, the risk of clogging of the juicer head is higher, and the reverse setting time can be relatively long. Therefore, the second reverse time is often greater than the first reverse time. The first total time and the second total time can be the same or different, and the first forward time can be the same or different, and there is no restriction here.

[0061] The various time periods here can be factory settings for the juicer, that is, these time periods can be pre-set and stored in the control system as default parameters and configurations, eliminating the need for the user to perform complex configurations upon first use. Alternatively, the user can be allowed to set these via the control panel described above, allowing the user to customize the time periods based on the characteristics of specific ingredients, thereby increasing the flexibility of the device.

[0062] Under the automatic forward and reverse control mode, the control system can select the first working gear or the second working gear according to the current feedback value of the current detection device. At this time, the specific working process of the control system is as follows: a matching first total time, first forward time and first reverse time, as well as a matching second total time, second forward time and second reverse time are preset, and the second reverse time is greater than the first reverse time; after the juicer power is started, the control system obtains the control mode of the juicer head. If the control mode is the automatic forward and reverse control mode, the real-time current flowing through the drive mechanism is obtained through the current detection device. If the real-time current is within the preset current range, it indicates that the texture of the current food is soft or the fiber is fine, and the total set time of the juicer is determined to be the first total time, the forward setting time of the juicer is determined to be the first forward time, and the reverse setting time of the juicer is determined to be the first reverse time. Then, within the first total set time, the driving mechanism drives the juicer head to rotate forward and reverse alternately according to the first forward time and the first reverse time; if the real-time current is outside the preset current range, it indicates that the texture of the current food is hard or the fiber is coarse, and the total set time of the juicer is determined to be the second total time, the reverse setting time of the juicer is determined to be the second forward time, and the reverse setting time of the juicer is determined to be the second reverse time. Then, within the second total set time, the driving mechanism drives the juicer head to rotate forward and reverse alternately according to the second forward time and the second reverse time.

[0063] Taking the control mode of the juicer head as the automatic forward and reverse control mode, the preset current range is 2A-5A (A is the current unit, ampere), the preset first total time is 180 seconds, the first forward time is 30 seconds, the first reverse time is 10 seconds, the second total time is 240 seconds, the second forward time is 25 seconds, and the second reverse time is 15 seconds. For example, the specific rotation process is as follows: the juicer starts and the current detection device starts working. If the real-time current feedback from the current detection device is 3A, which is within the preset current range (2A-5A), it indicates that the current food has a softer texture or finer fibers. The juicer head rotates forward and reverse alternately according to the first forward time (30 seconds) and the first reverse time (10 seconds) within the first total time (180 seconds). If the real-time current feedback from the current detection device is 5.5A, which exceeds the preset current range, indicating that the texture of the current food is hard or the fiber is coarse, the juicer head will rotate forward and reverse alternately according to the second forward rotation time (25 seconds) and the second reverse rotation time (15 seconds) within the second total time (240 seconds).

[0064] In this embodiment, the current detection device is arranged in series on the circuit of the drive mechanism and is electrically connected to the main control board. The real-time current flowing through the drive mechanism is monitored by the current detection device. The main control board can automatically select the appropriate total set time, forward set time and reverse set time according to the real-time current feedback value to achieve automatic control.

[0065] The current monitoring device may include a Hall effect current sensor and a current signal amplifier. The Hall effect current sensor is connected in series with the drive mechanism circuit to detect the current flowing through the drive mechanism. The current signal amplifier is electrically connected to the Hall effect current sensor and the main control board to amplify, filter, and process the Hall effect current sensor output signal before transmitting it to the main control board. The main control board then selects the total set time, the forward rotation set time, and the reverse rotation set time based on the real-time current feedback value.

[0066] Regarding rotation frequency, the control method of the present invention allows users to customize forward and reverse rotation frequencies. For example, in one embodiment, the control system includes a main control board and a control panel. The main control board is located on the body of the juicer and electrically connected to the drive mechanism. The control panel is located on the surface of the juicer and electrically connected to the main control board. The control panel includes a forward frequency setting module and a reverse frequency setting module.

[0067] At this time, refer to Figure 9 If the control mode is the automatic forward and reverse control mode, the control method further includes the following steps: The forward frequency setting module is used to obtain the forward frequency setting of the juicer, and the reverse frequency setting module is used to obtain the reverse frequency setting of the juicer; The juice extracting head is controlled to rotate forward according to the forward rotation setting frequency during the forward rotation period, and is controlled to rotate reversely according to the reverse rotation setting frequency during the reverse rotation period.

[0068] At this time, the specific working process of the control system is as follows: after the juicer power is started, the control system obtains the control mode of the juicer head. If the control mode is the automatic forward and reverse control mode, the total set working time of the juicer, the forward set time and the reverse set time are obtained. Then, within the total set time, the driving mechanism drives the juicer head to rotate forward and reverse alternately according to the forward set time and the reverse set time, and controls the juicer head to rotate forward according to the forward set frequency during the forward period, and controls the juicer head to reverse according to the reverse set frequency during the reverse period.

[0069] The forward rotation frequency setting is the number of times the juicing head completes a forward rotation cycle per unit time, while the reverse rotation frequency setting is the number of times the juicing head completes a reverse rotation cycle per unit time. This embodiment allows users to customize the forward and reverse rotation frequencies through the control panel. Different ingredients have different textures and fiber content, so users can adjust the rotation frequency of the juicing head to suit their specific ingredients. For harder ingredients like carrots, the forward rotation frequency can be increased to enhance the squeezing force, while the reverse rotation frequency can be appropriately increased to prevent clogging, thereby improving juicing efficiency.

[0070] It should be noted that the forward setting frequency is the frequency at which the juicer head is expected to be in a stable forward rotation, and the reverse setting frequency is the frequency at which the juicer head is expected to be in a stable reverse rotation. When the juicer head switches from forward rotation to reverse rotation, or from reverse rotation to forward rotation, it cannot immediately reach the set frequency, but must go through a deceleration phase, a short pause, and a speed-up phase to achieve a smooth speed and direction switching. Specifically, when the juicer head needs to switch from forward rotation to reverse rotation, or from reverse rotation to forward rotation, the speed of the juicer head will gradually decrease until it stops completely. After the deceleration phase is completed, the juicer head can pause for about 1 second. After a short pause, the juicer head gradually accelerates until it reaches the set forward or reverse frequency, thereby ensuring a smooth transition of speed and direction.

[0071] It is worth mentioning that the control panel in this embodiment can be equipped with the total time setting module, forward time setting module and reverse time setting module mentioned above at the same time. At this time, the user can customize the total set time, forward set time, reverse set time, forward set frequency and reverse set frequency through the control panel, thereby enhancing the user's operational flexibility and the intelligence level of the equipment.

[0072] Alternatively, in another embodiment, the control system pre-sets selectable forward and reverse frequencies. In this case, the control system includes a main control board and a current detection device. The main control board is located within the juicer body and electrically connected to the drive mechanism. The current detection device is connected in series with the drive mechanism's circuitry and electrically connected to the main control board. The current detection device monitors the real-time current flowing through the drive mechanism and transmits this real-time current to the main control board, which then automatically selects the forward and reverse frequencies based on the real-time current feedback.

[0073] At this time, refer to Figure 10 , the control method further comprises the following steps: A first forward frequency and a first reverse frequency that match each other, as well as a second forward frequency and a second reverse frequency that match each other are preset, wherein the second forward frequency is greater than the first forward frequency, and the second reverse frequency is greater than the first reverse frequency; If the control mode is the automatic forward and reverse control mode, the real-time current flowing through the drive mechanism is obtained by the current detection device; If the real-time current is within a preset current range, determining that the forward rotation frequency of the juicer head in the forward rotation period is a first forward rotation frequency, determining that the reverse rotation frequency of the juicer head in the reverse rotation period is a first reverse rotation frequency, controlling the juicer head to rotate forward according to the first forward rotation frequency in the forward rotation period, and controlling the juicer head to rotate reversely according to the first reverse rotation frequency in the reverse rotation period; If the real-time current is outside the preset current range, the forward rotation frequency of the juicer head in the forward rotation period is determined to be the second forward rotation frequency, and the reverse rotation frequency of the juicer head in the reverse rotation period is determined to be the second reverse frequency. The juicer head is controlled to rotate forward according to the second forward rotation frequency in the forward rotation period, and the juicer head is controlled to reverse according to the second reverse frequency in the reverse rotation period.

[0074] In this embodiment, the juicer control system is provided with a first working gear and a second working gear. The first forward frequency and the first reverse frequency correspond to the first working gear, and the second forward frequency and the second reverse frequency correspond to the second working gear. When the food texture is soft or the fibers are fine, the first working gear can be selected for operation. When the food texture is hard or the fibers are coarse, the second working gear can be selected for operation. When the food texture is soft or the fibers are fine, the risk of the juicer head getting stuck is low, and the forward frequency and the reverse frequency can be relatively low. When the food texture is hard or the fibers are coarse, the risk of the juicer head getting stuck is high, and the forward frequency and the reverse frequency can be relatively high. Therefore, the second forward frequency is often greater than the first forward frequency, and the second reverse frequency is often greater than the first reverse frequency.

[0075] The first forward frequency, the first reverse frequency, the second forward frequency, and the second reverse frequency can be factory settings of the juicer. That is, these frequency values can be pre-set and stored as default parameters and configurations in the control system, eliminating the need for the user to perform complex configurations upon first use. Alternatively, the user can be allowed to set these frequencies through the control panel described above, allowing the user to customize each rotation frequency as needed, thereby increasing the flexibility of the device.

[0076] Under the automatic forward and reverse control mode, the control system can select the first working gear or the second working gear according to the current feedback value of the current detection device. At this time, the specific working process of the control system is as follows: a matching first forward frequency and first reverse frequency, as well as a matching second forward frequency and second reverse frequency are preset, and the second forward frequency is greater than the first forward frequency, and the second reverse frequency is greater than the first reverse frequency; after the juicer power is started, the control system obtains the control mode of the juicer head. If the control mode is the automatic forward and reverse control mode, the total set working time, forward set time and reverse set time of the juicer are obtained, and the real-time current flowing through the drive mechanism is obtained through the current detection device. If the real-time current is within the preset current range, it indicates that the texture of the current food is relatively soft or the fiber is relatively fine. The forward rotation frequency of the juicer head in the forward rotation period is determined to be the first forward rotation frequency, and the reverse rotation frequency of the juicer head in the reverse rotation period is determined to be the first reverse rotation frequency. Within the total set time, the juicer head is controlled by the driving mechanism to rotate forward and reverse alternately according to the forward rotation set time and the reverse rotation set time, and the juicer head is controlled to rotate forward according to the first forward rotation frequency in the forward rotation period, and the juicer head is controlled to reverse according to the first reverse frequency in the reverse rotation period; if the real-time current is outside the preset current range, it indicates that the texture of the current food is relatively hard or the fiber is relatively coarse. The forward rotation frequency of the juicer head in the forward rotation period is determined to be the second forward rotation frequency, and the reverse rotation frequency of the juicer head in the reverse rotation period is determined to be the second reverse frequency. Within the total set time, the juicer head is controlled by the driving mechanism to rotate forward and reverse alternately according to the forward rotation set time and the reverse rotation set time, and the juicer head is controlled to rotate forward according to the second forward rotation frequency in the forward rotation period, and the juicer head is controlled to reverse according to the second reverse frequency in the reverse rotation period.

[0077] In this embodiment, the current detection device is set in series on the circuit of the drive mechanism and is electrically connected to the main control board. The current detection device monitors the real-time current flowing through the drive mechanism. The main control board can automatically select the appropriate forward rotation frequency and reverse rotation frequency according to the real-time current feedback value. This design enables the juicer to automatically select the rotation parameters according to the texture and fiber content of different ingredients to achieve automatic control.

[0078] It should be noted that in the control method of the present invention, after the juicer is started, the juicer head may first rotate forward and then reverse, that is, it may alternate according to the rule of "forward-reverse-forward-reverse". When the juicer is just started, the ingredients are relatively fresh, and the forward rotation can be used to quickly squeeze out the juice from the ingredients, and then the reverse rotation can be used to comb the fibers to prevent clogging. Alternatively, after the juicer is started, the juicer head may first reverse and then rotate forward, that is, it may alternate according to the rule of "reverse-forward-reverse-forward". This mode is suitable for situations where continuous juicing is required, especially when continuously squeezing ingredients with more fibers and a harder texture (such as carrots and celery). When the juicer is juicing multiple times in a row, the residue left over from the previous juicing may cause the juicing head to become stuck when it is turned on. Reversing the rotation first can clean the residue left over from the previous juicing, ensuring that each juicing can proceed smoothly and improving the reliability of the machine.

[0079] In one embodiment, the automatic forward and reverse control mode includes a first forward and reverse control mode and a second forward and reverse control mode. The first forward and reverse control mode is an alternating control of first forward rotation and then reverse rotation, and the second forward and reverse control mode is an alternating control of first reverse rotation and then forward rotation.

[0080] At this time, refer to Figure 11 If the control mode is the first forward and reverse control mode, within the total set time, the driving mechanism first controls the juicer head to rotate forward according to the forward rotation set time, and then controls the juicer head to reverse according to the reverse rotation set time, and controls the juicer head to rotate forward and reverse alternately according to the forward rotation set time and the reverse rotation set time.

[0081] If the control mode is the second forward and reverse control mode, within the total set time, the driving mechanism first controls the juicer head to reverse according to the reverse set time, and then controls the juicer head to forward according to the forward set time, and controls the juicer head to reverse and forward alternately according to the reverse set time and the forward set time.

[0082] Specifically, after the juicer is powered on, the control system obtains the control mode of the juicer head. If the control mode is the first forward-reverse control mode, the total set time, forward set time, and reverse set time of the juicer operation are obtained. Within the total set time, the driving mechanism first controls the juicer head to rotate forward according to the forward set time, then controls the juicer head to reverse according to the reverse set time, and then controls the juicer head to rotate forward and reverse alternately according to the forward set time and the reverse set time. If the control mode is the second forward-reverse control mode, the total set time, forward set time, and reverse set time of the juicer operation are obtained. Within the total set time, the driving mechanism first controls the juicer head to reverse according to the reverse set time, then controls the juicer head to rotate forward according to the forward set time, and then controls the juicer head to rotate reverse and forward alternately according to the reverse set time and the forward set time.

[0083] Among them, the control system can also include a first button corresponding to the first forward and reverse control mode and a second button corresponding to the second forward and reverse control mode. The first button and the second button are arranged on the surface of the juicer. The control system determines that the automatic forward and reverse control mode is the first forward and reverse control mode through the first button, and determines that the automatic forward and reverse control mode is the second forward and reverse control mode through the second button.

[0084] Specifically, the first button and the second button are electrically connected to the main control board inside the juicer. When the first button is pressed, the main control board determines that the juicer's control mode is the first forward and reverse control mode. When the second button is pressed, the main control board determines that the juicer's control mode is the second forward and reverse control mode. The configuration of the first button and the second button allows the user to directly select the first forward and reverse control mode or the second forward and reverse control mode, enhancing the convenience and flexibility of user operation. The first button and the second button can be physical buttons located on the surface of the juicer, or the first button and the second button can be touch-screen buttons located on the control panel.

[0085] Reference Figure 6 or Figure 7 In some embodiments of the control method of the present invention, the control mode of the control system may further include a full forward control mode and a full reverse control mode. If the control mode is the full forward control mode, the control system controls the juicer head to rotate forward through the driving mechanism; if the control mode is the full reverse control mode, the control system controls the juicer head to rotate reversely through the driving mechanism. That is, in the full forward control mode, the juicer head only rotates forward and does not reverse, which is suitable for situations where the juicing task needs to be completed quickly. In the full forward control mode and the full reverse control mode, the juicer head only reverses and does not rotate forward, which is suitable for situations where residues are specifically cleaned. The settings of the full forward control mode and the full reverse control mode enable the juicer to adapt to more usage scenarios and needs, further improving the flexibility of the juicer.

[0086] The control system includes a first mode selection button corresponding to the automatic forward and reverse control mode, a second mode selection button corresponding to the full forward control mode, and a third mode selection button corresponding to the full reverse control mode. The first, second, and third mode selection buttons are located on the surface of the juicer. The control system selects the automatic forward and reverse control mode using the first mode selection button, the full forward control mode using the second mode selection button, and the full reverse control mode using the third mode selection button.

[0087] Specifically, the first mode selection button, the second mode selection button, and the third mode selection button are electrically connected to the main control board within the juicer. The first mode selection button includes a first button and a second button. When the first button is pressed, the main control board determines the juicer's control mode to be the first forward-reverse control mode. When the second button is pressed, the main control board determines the juicer's control mode to be the second forward-reverse control mode. When the second mode selection button is pressed, the main control board determines the juicer's control mode to be the full forward control mode, and the main control board drives the juicer head forward via a drive mechanism. When the third mode selection button is pressed, the main control board determines the juicer's control mode to be the full reverse control mode, and the main control board drives the juicer head reversely via a drive mechanism. The first mode selection button, the second mode selection button, and the third mode selection button can be physical buttons located on the surface of the juicer, or touchscreen buttons located on a control panel. Alternatively, the first mode selection button, the second mode selection button, and the third mode selection button can be three different gears of a single knob.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
