[0010] Optionally, a sliding groove is provided in the middle of the connecting rod, and a connecting portion connected to the sliding groove is provided at an eccentric position of the turntable. When the connecting rod rotates eccentrically, the connecting portion slides in the sliding groove.

[0030] With the growing demand for healthy diets, juicers have become one of the essential household appliances in home kitchens. However, existing juicers usually use manual operation by users when feeding squeezed materials, which is troublesome to operate and requires high user participation, making it inconvenient for users to use the juicer. When more squeezed materials need to be squeezed, users are required to feed squeezed materials next to the juicer all the time, which is not conducive to user use, increases the labor intensity of users, and has low feeding efficiency, resulting in low overall squeezing efficiency. To this end, the utility model proposes a feeding device, which aims to improve the degree of automation of feeding squeezed materials into the juicer, reduce the workload of users, and improve the overall squeezing efficiency of the juicer.

[0031] The utility model proposes a feeding device. To facilitate understanding of the utility model, the juicing process of the juicer is first introduced. The squeezed object 900 squeezed by the juicer is introduced by taking orange as an example. Figures 1 to 5 The juicer includes a filter 300, a frame 400, a base 500, a rolling plate 600, a first driving device 710, a second driving device 720, and a juice storage box 800, wherein the filter 300 for holding oranges is installed on the base 500, the rolling plate 600 is arranged on the frame 400 above the filter 300, and forms a squeezing space with the filter 300, the filter 300 is provided with a filter hole 310, the juice storage box 800 is arranged below the filter 300, and is used to receive the orange juice flowing out of the filter hole 310, the first driving device 710 and the second driving device 720 are both arranged on the frame 40 0, when juicing, the first driving device 710 drives the rolling disc 600 to perform oscillatory rolling, and the second driving device 720 drives the base 500 to move toward the rolling disc 600. At this time, the filter 300 follows the base 500 to move toward the rolling disc 600 to reduce the squeezing space so that the oranges are squeezed to extract juice between the filter 300 and the rolling disc 600. After juicing is completed, the first driving device 710 stops driving the oscillatory movement of the rolling disc 600, and the second driving device 720 drives the base 500 to drive the filter 300 to move in a direction away from the rolling disc 600, thus completing one juicing operation.

[0032] It is worth mentioning that the squeezed object 900 in the present application is not limited to oranges, but can also be grapes, watermelons, cucumbers, tomatoes and other objects.

[0033] Reference Figures 1 to 5In the technical solution of the utility model, the feeding device is applied to the juicer, and the feeding device includes a feeding box 100 and a feeding mechanism 200. The feeding box 100 has a feeding port 120, a discharging port 130, and a ramp 110 connecting the feeding port 120 and the discharging port 130. The ramp 110 extends downward from the feeding port 120 to the discharging port 130 and can store a plurality of squeezed materials 900. The lower end of the slope of the ramp 110 is provided with a feeding port 160 and a baffle. 150, a feed opening 160 is provided on a side of the baffle 150 away from the discharge opening 130, the feed opening mechanism 200 is provided on the feed box 100, and the feed opening mechanism 200 includes a driving module 210 and a lifting platform 220 drivingly connected to the driving module 210, and the lifting platform 220 can move in the up-down direction at the feed opening 160 to lift the squeezed material 900 located above the feed opening 160, and make the squeezed material 900 pass over the baffle 150 and fall to the discharge opening 130. It is worth noting that the squeezed oranges in this application are complete oranges with peels. A feeding port 120 is provided for feeding the squeezed material 900 into the feeding box 100, and a ramp 110 box and a discharge port 130 connected to the ramp 110 are provided on the feeding box 100, so that the oranges placed on the ramp 110 can roll spontaneously along the ramp 110 to the discharge port 130 under the action of gravity to provide the squeezed material 900 to the juicer, and a baffle 150 is provided at the lower end of the slope of the ramp 110 to prevent the squeezed material 900 from rolling spontaneously on the slope to the discharge port 130, so that the feeding box 100 can store multiple squeezed materials 900 at the same time. In this way, the lifting mechanism 200 is provided. When the feed box 100 puts oranges into the juicer, the driving module 210 drives the lifting platform 220 to move toward the lifting port 160 to lift the oranges, so that the oranges pass over the baffle 150 and fall to the discharge port 130. The oranges finally fall into the juicer for squeezing. When the driving module 210 drives the lifting platform 220 away from the lifting port 160, the oranges are blocked by the baffle 150 and will not roll to the discharge port 130 spontaneously, so that the feed box 100 can provide oranges to the juicer one by one, so that the juicer will not squeeze multiple oranges at the same time, which will cause the juicer to squeeze the oranges insufficiently. In this way, the automatic feeding function of the feed box 100 for juicing is realized, the degree of automation of feeding the juicer is improved, the workload of the user is reduced, and the squeezing efficiency of the juicer is improved. When more oranges need to be squeezed, the user only needs to put the pre-prepared oranges into the supply box 100, and the supply box 100 will automatically and continuously supply oranges to the juicer. The user does not need to stay by the juicer all the time to supply oranges to the juicer, which greatly reduces the user's workload and brings greater convenience to the user in operating the juicer.

[0034] Optionally, in one embodiment, the protruding height of the baffle 150 on the slope is configured to be 35 mm to 50 mm. Thus, when the protruding height of the baffle 150 on the slope is set to be less than 35 mm, due to the different sizes of oranges, oranges with larger volumes may still roll to the discharge port 130 spontaneously under the action of gravity, so that the juicer squeezes multiple oranges at the same time, which may easily lead to insufficient squeezing of the oranges by the juicer; when the protruding height of the baffle 150 on the slope is even greater than 50 mm, the baffle 150 may still block the oranges when the lifting platform 220 lifts the oranges due to the excessive protruding height, so that the oranges still cannot pass over the baffle 150 and fall to the discharge port 130, so that the supply box 100 cannot put the oranges into the juicer, causing the juicer to work abnormally. Therefore, the protruding height of the baffle 150 on the slope is set within a more appropriate range of 35 mm to 50 mm. On the one hand, the baffle 150 has a more appropriate height to block oranges with a larger volume so that the oranges cannot spontaneously pass over the baffle 150 and fall to the discharge port 130. On the other hand, when the lifting platform 220 lifts the oranges, the baffle 150 will not continue to block the oranges, so that the oranges can smoothly pass over the baffle 150 and fall to the discharge port 130 to provide the oranges to the juicer.

[0035] Optionally, in another implementation, the protruding height of the baffle 150 on the slope can be set in many ways, and the protruding height of the baffle 150 on the slope can also be set at 55 mm.

[0036] Optionally, in one embodiment, the feed box 100 further has a receiving chamber 170 connected to the top material port 160 , the receiving chamber 170 extends below the ramp 110 , and the lifting platform 220 moves up and down in the receiving chamber 170 under the drive of the driving module 210 . In this way, the lifting platform 220 is arranged in the receiving cavity 170, and the multi-sided side walls in the receiving cavity 170 form a track for the lifting platform 220 to move, so as to limit the movement of the lifting platform 220 around the receiving cavity 170, so that the lifting platform 220 moves up and down along the track formed by the receiving cavity 170 under the drive of the driving module 210, and does not move toward the side of the receiving cavity 170, so that the end of the lifting platform 220 close to the top material port 160 rises in the direction of the top material port 160 to accurately lift the oranges located above the top material port 160. It is worth mentioning that the diameter of the top material port 160 is smaller than the radial size of the orange, so that the orange will not fall from the top material port 160 into the receiving cavity 170.

[0037] Optionally, in another implementation, there may be many structural forms for limiting the displacement of the lifting platform 220. A guide rail connected to the top material port 160 may be provided on one side of the length direction of the feed box 100 and the lifting platform 220. The lifting platform 220 is driven by the driving module 210 and moves up and down in the track direction of the guide rail.

[0038] Optionally, in one embodiment, the lifting mechanism 200 also includes a connecting rod 230 connecting the driving module 210 and the lifting platform 220, and a turntable 240 drivingly connected to the output shaft of the driving module 210. The middle part of the connecting rod 230 is slidably connected to the eccentric part of the turntable 240, so that the connecting rod 230 can make eccentric rotation during the rotation of the turntable 240. One end of the connecting rod 230 is rotatably connected to the outer shell of the driving module 210, and the other end of the connecting rod 230 is slidably connected to the lifting platform 220, so that the lifting platform 220 makes a linear reciprocating motion in the accommodating cavity 170. In this way, when the driving module 210 drives the turntable 240 to rotate, the turntable 240 drives the connecting rod 230 to rotate. Since the middle part of the connecting rod 230 is slidingly connected to the turntable 240, the middle part of the connecting rod 230 can follow the turntable 240 to make eccentric rotation. At this time, the position of one end of the connecting rod 230 connected to the shell of the driving module 210 on the driving module 210 remains unchanged. Therefore, the end of the connecting rod 230 connected to the lifting platform 220 follows the movement of the turntable 240 and makes a linear reciprocating motion in the receiving chamber 170, thereby realizing the function of the lifting platform 220 rising and falling in the receiving chamber 170.

[0039] Optionally, in another implementation, there may be a variety of structures to enable the lifting platform 220 to rise and lift the oranges and lower them in the receiving chamber 170. A screw motor may also be provided to directly drive the lifting platform 220 to rise and lift the oranges and lower them below the top material port 160.

[0040] Optionally, in one embodiment, a slide groove 250 is provided in the middle of the connecting rod 230, and a connecting portion 260 connected to the slide groove 250 is provided at the eccentric portion of the rotating disk 240, and when the connecting rod 230 rotates eccentrically, the connecting portion 260 slides in the slide groove 250. The slide groove 250 is provided in the middle of the connecting rod 230, and when the connecting rod 230 rotates driven by the rotating disk 240, the connecting portion 260 can slide in the slide groove 250, so that the connecting rod 230 can rotate eccentrically driven by the rotating disk 240, so that the end of the connecting rod 230 connected to the lifting platform 220 can perform linear reciprocating motion, so as to realize the lifting and lowering of the lifting platform 220.

[0041] Optionally, in another embodiment, there may be multiple forms of connection between the connecting rod 230 and the turntable 240. A waist-shaped hole may be opened in the middle of the connecting rod 230, and a connecting piece passing through the waist-shaped hole may be provided on the turntable 240. A nut may be provided at one end of the connecting piece close to the waist-shaped hole to limit the connecting piece from being separated from the waist-shaped hole. The connecting piece may slide in the waist-shaped hole, so that the connecting rod 230 may rotate eccentrically.

[0042] Optionally, in one embodiment, the slope of the lowest ramp 110 includes an upper slope section 111 and a lower slope section 112 connected to each other, the slope of the lower slope section 112 is greater than the slope of the upper slope section 111, the top material port 160 is disposed in the lower slope section 112, and the end of the lifting platform 220 close to the top material port 160 has the same slope as the lower slope section 112. In this way, the slope of the lower section of the slope of the most downward ramp 110 is set to be greater than the slope of the upper section 111 of the slope. On the one hand, the center of gravity of the orange on the slope is lowered, so that the orange is not easy to spontaneously pass over the baffle 150 and fall to the discharge slope 140. On the other hand, the slope of the lower section 112 of the slope is greater than the slope of the upper section 111 of the slope, so that the orange has a greater gravitational potential energy in the lower section 112 of the slope than in the upper section 111 of the slope, so that the orange is easier to fall to the discharge slope 140 under the lifting of the lifting platform 220, and finally falls on the filter 300. The end of the lifting platform 220 close to the top material port 160 is set to be consistent with the ramp 110 of the lower section of the slope, so that the orange lifted by the lifting platform 220 is easier to pass over the baffle 150 and fall to the discharge port 130.

[0043] Optionally, in another embodiment, the upper and lower sections of the lowest slope can be arranged in many forms, and the lower section 112 of the slope can be arranged directly below the upper section 111 of the slope, so that the upper section 111 of the slope and the lower section 112 of the slope overlap in the height direction of the supply box 100. In this way, the oranges can roll from the upper section 111 of the slope to the lower section 112 of the slope, and the oranges in the lower section 112 of the slope have a lower center of gravity, making it difficult for the oranges to spontaneously cross the baffle 150 and fall to the discharge slope 140.

[0044] Optionally, in one embodiment, the feed box 100 further has a discharge slope 140, the upper end of the discharge slope 140 is connected to the lower end of the lowest ramp 110, and extends downwardly along the width direction of the ramp 110, the lower end of the discharge slope 140 passes through the side wall of the feed box 100 and forms a discharge port 130, and the slope surface of the discharge slope 140 is a concave arc surface convex downward. In this way, a baffle 150 is provided on the lower ramp 110 near the discharge ramp 140 to block the oranges rolling onto the lower ramp 110 on the slope of the lower ramp 110, so that the oranges will not roll to the discharge port 130 spontaneously, and the oranges will be accumulated on the lower ramp 110, thereby realizing the storage function of the supply box 100 for oranges; the discharge ramp 140 is configured to be in the form of a concave arc surface, and the oranges can be guided along the concave arc surface to the top of the filter 300, so that the oranges can be accurately placed on the filter 300 for the juicer to squeeze and extract juice, and the concave arc surface of the discharge ramp 140 can also reduce the friction between the discharge ramp 140 and the oranges and the impact force on the oranges, thereby reducing damage to the oranges.

[0045] Optionally, in another implementation, the discharge slope 140 with a concave arc surface may not be provided, and the discharge port 130 may be provided above the filter 300. The oranges may roll directly from the lower ramp 110 to the discharge port 130 and fall onto the filter 300 at the discharge port 130 to be squeezed by the juicer.

[0046] Optionally, in one embodiment, the angle at which the ramp 110 is inclined downwardly toward the feed box 100 is configured to be in the range of 50 to 150. In the length direction of the ramp 110, when the angle between the slope of the ramp 110 and the horizontal plane is set to be less than 5°, the angle between the slope of the ramp 110 and the horizontal plane is too small, so that the gravitational potential energy of the oranges placed on the ramp 110 is small, and the friction between the oranges and the slope cannot be overcome, and the oranges are not easy to roll on the slope, resulting in the feed box 100 being unable to transport the oranges to the filter 300; when the angle between the slope of the ramp 110 and the horizontal plane is set to be greater than 15°, due to the large slope of the ramp 110, the depth of the ramp 110 extending downwardly is greater, and therefore, an even longer length of the feed box 100 is required, which increases the height dimension of the feed box 100, thereby increasing the occupied space and production cost of the feed box 100. Therefore, the angle between the slope and the horizontal plane is set at 5° to 15°. On the one hand, the oranges placed on the ramp 110 can have sufficiently large gravitational potential energy so that the oranges can roll along the slope toward the discharge port 130. On the other hand, the height dimension of the feeding box 100 can be controlled within a more appropriate range so that the dimension of the feeding box 100 in the height direction will not be too large, which will lead to increased production costs and occupied space.

[0047] Optionally, in another implementation, the angle between the slope and the horizontal plane can also be set at 20°, so that the oranges placed on the ramp 110 have sufficient gravitational potential energy and can roll along the slope of the ramp 110 toward the discharge port 130.

[0048] The utility model also proposes a juicer, which includes the aforementioned filter 300, a rolling plate 600, a frame 400, a base 500, a first drive device 710, a second drive device 720, a juice storage box 800, and a feeding device. The specific structure of the feeding device refers to the above-mentioned embodiment. Since the juicer adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0049] Optionally, in one embodiment, the feeding device is detachably mounted on the juice extractor. In this way, the feeding device is detachably mounted on the juice extractor, which is convenient for the user to install and disassemble the feeding device and to disassemble, repair or replace the feeding device later.

[0050] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
