Description

Technical Field

[0001] This invention relates to the field of juicer technology, and more particularly to an electric juicer. Background Technology

[0002] With the continuous improvement of living standards, people's nutritional and health needs in their diets are also increasing. For a balanced daily diet, a certain amount of vitamins and trace elements are required. Fruits and vegetables contain a large amount of vitamins and trace elements and are an important part of people's daily diet. A juicer is a machine that can quickly extract juice from fruits and vegetables. It can juice various kinds of fruits and vegetables and allows users to choose according to their preferences, making it convenient for people to consume fruits and vegetables. It is a common small household appliance. Currently, most juicers rely on AC power to rotate the blades to press fruits and vegetables. Outdoor juicers without AC power mainly use sharp blades to stir or press, and do not have the ability to change the direction of rotation of the pressing cylinder or continuously adjust the cylinder speed (acceleration or deceleration). Therefore, when making juice, they cannot simultaneously adjust to fruits and vegetables with large differences in hardness (such as sugarcane), nor do they provide users with safe, easy, and quick cleaning functions.

[0003] In conclusion, existing juicers clearly have inconveniences and defects in practical use, so it is necessary to improve them. Summary of the Invention

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0055] like Figure 1 As shown, this invention provides an electric juicer 100, including a main body 1, a left shell 2, a right shell 3, at least two sets of gear assemblies 4, a motor 5, an electronic base plate assembly 6, a juice tray 01, a drain tray 02, and a bottom shell 9. In this embodiment, there are three sets of identical gear assemblies 4, installed on the left and right sides of the main body 1 respectively. The left gear assembly 4 and the right gear assembly 4 of the main body 1 are identical. Only the three sets of gear assemblies 4 installed on the right side of the main body 1 are shown in the figure. The motor 5 and the electronic base plate assembly 6 are electrically connected to each other and fixed inside the main body 1. The gear assemblies 4 are snapped onto both sides of the main body 1. The left shell 2 is snapped onto the left side of the main body 1, and the right shell 3 is snapped onto the right side of the main body 1. The left shell 2 and the right shell 3 are fixed to the main body 1 by snapping without the need for screws, making operation simple and convenient. The bottom shell 9 is snapped onto the bottom of the main body 1. The juice tray 01 and the drain tray 02 are placed inside the bottom shell 9, with the drain tray 02 placed on top of the juice tray 01.

[0056] like Figures 2-4 The diagram shows the steps for engaging the left shell 2 and the right shell 3 with the main body 1. Specifically, the engagement of the left shell 2 with the left side of the main body 1 is accomplished in three steps: First, insert the lifting cap 111 into the upper left of the main body 1; second, insert the four M slots 22 on the top of the left shell 2 into the four L slots 11 on the top left side of the main body 1; third, insert the L slots 21 on the lower side of the left shell 2 into the slots 12 on the bottom left side of the main body 1. After engagement, the left shell 2 and the right side of the main body 1 are fixedly engaged. The snap-fit ​​connection between the right side shell 3 and the right side of the main body 1 is completed in three steps. First, insert the carrying tube 110 from the upper left circular hole of the main body 1 into the upper right circular hole of the main body 1, then insert the carrying tube cap 111 into the upper right side of the main body 1. Second, insert the four M slots 12 on the top of the right side shell 3 into the four L slots 11 on the top right side of the main body 1. Third, insert the L slots on the lower side of the right side shell 3 into the slots 12 on the bottom left side of the main body 1. After snap-fit, the right side shell 3 and the right side of the main body 1 are fixedly snapped together. This snap-fit ​​assembly method is convenient, eliminating the need for screws or tools, saving labor, and is also compact, easy to store and carry.

Each gear assembly 4 is installed at both ends of a corresponding pressure cylinder 15. The two gear assemblies 4 drive the two pressure cylinders 15 to rotate respectively. The space gap between the two rotating pressure cylinders 15 can press the target pressing object.

[0058] Preferably, the electric juicer 100 includes at least a first gear assembly 401, a second gear assembly 402, and a third gear assembly 403. The pressure cylinder 15 includes a first pressure cylinder 151, a second pressure cylinder 152, and a third pressure cylinder 153. The two ends of the first gear assembly 401, the second gear assembly 402, and the third gear assembly 403 are respectively mounted on the two ends of the first pressure cylinder 151, the second pressure cylinder 152, and the third pressure cylinder 153. The first gear assembly 401, the second gear assembly 402, and the third gear assembly 403 respectively drive the first pressure cylinder 151, the second pressure cylinder 152, and the third pressure cylinder 153 to rotate. Changing the distance between the first pressure cylinder 151 and the second pressure cylinder 152 and the third pressure cylinder 153 can press the target object.

[0059] Preferably, the electric juicer 100 further includes a width adjustment device fixed within the main body 1. The width adjustment device includes a width adjustment assembly 16, a pair of first arms 13, and a pair of second arms 14. The width adjustment assembly 16 includes a rotating shaft 161 and a pair of gear mechanisms 162, with the pair of gear mechanisms 162 respectively disposed on the rotating shaft 161. The pair of first arms 13 are respectively fixed to both ends of the first pressure cylinder 151. One end of each first arm 13 is provided with a rack, which meshes with the pair of gear mechanisms 162. The other end of each first arm 13 is connected to one end of each second arm 14. The ends are rotatable shaft connections; the pair of second arms 14 are bent and fixed to the two ends of the second pressure cylinder 152 and the third pressure cylinder 153 respectively; after the rotating shaft 161 of the width adjustment device is rotated, the rotating shaft 161 drives the pair of gear mechanisms 162 to rotate, and the pair of gear mechanisms 162 drives the racks of the pair of first arms 13 to move, changing the distance between the first pressure cylinder 151 and the second pressure cylinder 152 and the third pressure cylinder 153 respectively, thereby adjusting the distance between the first gear assembly 401 and the second gear assembly 402 and the third gear assembly 403 respectively, such as Figures 9-10As shown, this embodiment has three pressure cylinders 15 and three sets of gear assemblies 4. The two ends of the first gear assembly 401, the second gear assembly 402, and the third gear assembly 403 are respectively mounted on the two ends of the first pressure cylinder 151, the second pressure cylinder 152, and the third pressure cylinder 153. The first gear assembly 401, the second gear assembly 402, and the third gear assembly 403 drive the first pressure cylinder 151, the second pressure cylinder 152, and the third pressure cylinder 153 to rotate, thereby changing the relative positions of the first pressure cylinder 151 and the second pressure cylinder 153. 52. The distance between the third pressure cylinders 153 allows for pressing the target material. The first pressure cylinder 151, the second pressure cylinder 152, and the third pressure cylinder 153 are each equipped with a pressure cylinder waterproof gasket 1501 and a pressure cylinder cover 1502. The pressure cylinder waterproof gasket 1501 is placed at both ends of the first pressure cylinder 151, the second pressure cylinder 152, and the third pressure cylinder 153. The pressure cylinder cover 1502 is inserted into both ends of the first pressure cylinder 151, the second pressure cylinder 152, and the third pressure cylinder 153. The three pressure cylinders 15 have the same structure. Figure 14 As shown, the main body 1 also includes a pair of first arms 13, a pair of second arms 14, a rotating shaft 161, a width adjustment handle 18, and a pair of second gears 1622. The rotating shaft 161 is a steel hexagonal shaft 161, and the pair of second gears 1622 are flat gears 1622. The width adjustment handle 18 drives the rotating shaft 161, causing the pair of first gears 1621 to rotate, which in turn drives the pair of second gears 1622 to rotate, changing the angle between the pair of first arms 13 and the pair of second arms 14, changing the distance between the first pressure cylinder 151 and the second pressure cylinder 152 and the third pressure cylinder 153 respectively, thereby adjusting the distance between the first gear assembly 401 and the second gear assembly 402 and the third gear assembly 403 respectively, and adjusting the pressing width, as shown. Figures 15-16 As shown, the width of the space gap in the pressure cylinder 15 can be adjusted by the width adjustment device. The appropriate space gap width can be adjusted according to the size of the target material to be pressed. The target materials to be pressed can be sugarcane, ginger, garlic, apple, carrot, celery, plum, orange, etc., all of which can be pressed efficiently. When cleaning, the simplest cleaning method is adopted. After use, it can be placed in the washing tray and rinsed with tap water. There is no need to touch the blades on the traditional juicer during cleaning, which is safe and achieves the simplest cleaning.

[0060] Preferably, the pair of gear mechanisms 162 of the width adjustment assembly 16 includes a pair of first gears 1621 and a pair of second gears 1622. The pair of first gears 1621 are respectively fixed to both ends of the rotating shaft 161, and the pair of second gears 1622 are respectively meshed with the pair of first gears 1621 and the pair of racks. When the rotating shaft 161 of the width adjustment device is rotated, it drives the pair of first gears 1621 to rotate. The pair of first gears 1621 drive the pair of second gears 1622 to rotate. The pair of second gears 1622 drive the racks to move, changing the distance between the first pressure cylinder 151 and the second pressure cylinder 152 and the third pressure cylinder 153, respectively, thereby adjusting the distance between the first gear assembly 401 and the second gear assembly 402 and the third gear assembly 403, respectively.

[0061] Preferably, the width adjustment device further includes a width adjustment handle 18, one end of which is fixed to one end of the rotating shaft 161, and the width adjustment handle is located outside the main body 1. The width adjustment handle 18 is used to continuously adjust the spatial gap or pressing width between the two pressing cylinders 15. By rotating the width adjustment handle 18, the first arm 13 is driven to move, and the angle of the opening between the first arm 13 and the two arms 05 is adjusted. The spatial gap width between the two pressing cylinders 15 of the electric juicer 100 can be easily and continuously adjusted to achieve crushing and pressing of various fruits and vegetables.

[0062] Preferably, the main body 1 has a rotation control component 7 inside and a steering control input unit outside the main body 1. The steering control component is electrically connected to the motor and the steering control input unit respectively. The steering control component controls the rotation direction of the motor according to the control command of the steering control input unit. The steering control input unit can be a button, key, touch screen, etc. Figures 21-22As shown, the rotation control assembly 7 includes a battery bracket 301, a battery negative contact 302, a battery positive contact 303, an electronic base plate 304, a charging socket 305, a speed control start switch 306, a motor reverse switch 307, a speed control potentiometer 308, a motor wiring connector 309, a rotation knob accessory 310, and a knob 311. After the battery negative contact 302 and battery positive contact 303 are inserted into the battery bracket 301, the battery is connected to the electronic base plate 304 via the contacts without wires. The electronic base plate 304 has a charging socket 305, a speed start switch 306, a motor reverse switch 307, a speed control potentiometer 308, and a motor connection connector 309 inserted into it. The motor connection connector 309 is connected to the motor 5 via a wire. The user rotates the steering control input unit 312, which drives the knob 311 and the rotating knob accessory 310 to start or adjust the speed start switch 306, the motor reverse switch 307, and the speed control potentiometer 308, so that the user can operate the pressure cylinder 15 with one hand. The steering and forward rotation speed are very convenient. When the steering control input unit 312 rotates counterclockwise, the pressure cylinder 15 rotates in the opposite direction; when the steering control input unit 312 rotates clockwise, the pressure cylinder 15 rotates in the forward direction. The rotation angle is proportional to the rotation speed. The charging socket 305 has a charging and speed indicator 313 on the right side. When charging or rotating the steering control input unit 312, the charging and speed indicator 313 displays the charging or speed. The main body 1, right shell 3, bottom shell 9, and rotation knob are also included. Accessories 310, 311, 301, 302, 303, 304, 305, 306, 307, 308, and 309 are integrally formed. The rotary knob accessories 310 and 311 are first installed on the right side shell 3, and then on the main body 1. The right side shell 3, rotary knob accessories 310, and 311 are integrally formed. Figures 23-25 As shown, viewed from the front of the right shell, the steering control input unit 312 on the lower left of the right shell 3 of the main body 1 rotates counterclockwise, causing the pressure cylinder 15 to reverse and retract from the fruit and vegetables being pressed. Viewed from the front of the right shell, when the steering control input unit 312 rotates clockwise, the pressure cylinder 15 rotates clockwise. The rotation speed of the pressure cylinder 15 depends on the rotation angle of the steering control input unit 312; the larger the rotation angle of the steering control input unit 312, the higher the rotation speed of the pressure cylinder 15. This speed adjustment is used to match different soft and hard fruits and vegetables, thus easily adjusting the optimal pressing effect. The pressure cylinder 15 reverses and retracts from the fruit and vegetables being pressed. By continuously changing the rotation direction of the pressure cylinder 15 through the steering control input unit, the juice of fruits and vegetables can be repeatedly, perfectly, and completely and quickly extracted, resulting in high efficiency. Figure 32 The diagram shows the assembly process of the electric juicer 100.

[0063] Preferably, the main body 1 is connected to an external power source, which supplies power to the electric juicer 100.

[0064] Preferably, the main body 1 is equipped with a rechargeable battery, which powers the electric juicer 100 and can be connected to an external power source. The motor 5 can be a DC motor. In this embodiment, a built-in lithium battery is used, which can press fruits and vegetables without external power. It is suitable for places where power supply is incomplete, such as picnics in the suburbs.

[0065] Preferably, the main body 1 is provided with a carrying tube 110 and two carrying tube caps 111 on the top. The carrying tube 110 is snapped into the main body 1, and the two carrying tube caps 111 at both ends of the carrying tube 111 are respectively snapped into the main body 1.

[0066] Preferably, the main body 1 is further provided with at least two rotating shafts 161, and at least two pressure cylinders 15 are inserted into and fixed to the two rotating shafts 161.

[0067] Preferably, the bottom of the main body 1 is provided with at least one slot, and the bottom shell 9 is provided with at least one corresponding snap-fit ​​member 91. The snap-fit ​​members 91 of the bottom shell 9 are respectively snapped into the slots at the bottom of the main body 1, such as... Figures 26-31 As shown, the bottom shell 9 has four snap-fit ​​pieces 91, and the bottom of the main body 1 has four slots. The snap-fit ​​pieces 91 match the slots on the bottom of the main body 1. The four snap-fit ​​pieces 91 of the bottom shell 9 are respectively snapped into the four slots on the bottom of the main body 1. After assembly, a small waterproof ring 03 and a width adjustment handle 18 are inserted into the left shell 2. Finally, a small waterproof ring 03, a knob 311, and a steering control input unit 312 are inserted into the right shell 3 to complete the assembly. The width adjustment handle 18 and the small waterproof ring are snapped into the main body 1. Shaking the width adjustment handle 18 drives a set of pressure cylinders 15 inside the main body 1, changing the distance between this set of pressure cylinders 15 and the other set of pressure cylinders 15, thus changing the distance between the two sets of pressure cylinders 15. The space between the parts allows for easy adjustment of the thickness of the pressed fruits and vegetables. The four snap-fit ​​pieces 91 are two snap-fit ​​pieces 91 on the left and two snap-fit ​​pieces 91 on the right. The two snap-fit ​​pieces 91 on the left and two snap-fit ​​pieces 91 on the right are snapped into the slots of the main body 1. The four slots are two slots on the left and two slots on the right. The assembly of the bottom shell 9 and the main body 1 is completed in two steps. The first step is to assemble the main body 1 onto the bottom shell 9. The two snap-fit ​​pieces 91 on the left side of the bottom shell 9 are snapped into the two slots on the left side of the bottom left of the main body 1. The second step is to snap the two snap-fit ​​pieces 91 on the right side of the bottom of the main body 1 into the two slots on the right side of the bottom. After assembly, the bottom shell 9 and the main body 1 will not separate.

[0068] Preferably, the gear assembly 4 includes a gear buckle 48, and the main body 1 includes a rotating shaft 161, which is inserted into the gear buckle 48 to fix the gear assembly 4, such as... Figures 11-13 As shown, the gear buckle 48 is engaged with the gear base 41. When the rotating shaft 161 is inserted, it blocks the three locking positions of the gear buckle 48, preventing it from disengaging. Figure 5 As shown, there are three pairs of gear assemblies 4, each pair being identical, installed on the left and right sides of the main body 1 respectively. The three pairs of gear assemblies 4 are slightly different, because the gear set on the left side of the main body 1 is the same as the gear set on the right side. Figure 5 Only the three gear assemblies 4 installed on the right side of the main body 1 are shown, such as Figure 6 As shown, the first group includes a gear base 41, a waterproof nitrile ring 42, a copper bearing 43, a gear clamp 44, an iron gear 46, and a gear buckle 48. After inserting the gear base 41 and the waterproof nitrile ring 42 into the main body 1 in sequence, the copper bearing 43, gear clamp 44, iron gear 46, gear clamp 44, gear buckle 48, and a gear assembly waterproof pad 49 are inserted in sequence. The two gear clamps 44 engage the iron gear 46 in opposite directions.
