Description

Technical Field

[0001] The invention relates to a horizontal juicer. Background Art

[0002] Juicers are generally classified into two types: horizontal and vertical. Both types include a juicer cup, a rotating screw propeller inside the juicer cup, and a motor that drives the screw propeller. In a horizontal juicer, the juicer cup and screw propeller are placed horizontally. The upper side wall of the juicer cup has an opening for feeding fruits or vegetables. The cutting section of the screw propeller cooperates with the inner wall of the juicer cup to crush the fruits or vegetables. The juice and residue are then separated at the grinding section of the screw propeller. The cutting section and the grinding section are coaxially arranged on the screw propeller. When cutting some food materials with strip-shaped fibers, if the long strips of food materials are not cut into multiple sections in advance, they are easily entangled in the cutting section of the screw propeller, affecting the juice yield.

[0003] Among them, there is a vertical blanking channel between the feed port and the cutting section of the spiral propeller. The diameter of the blanking channel corresponds to the diameter of the spiral propeller. A part of the cutting section can extend upward from the lower end of the blanking channel into the blanking channel when rotating. If the length of the blanking channel is too long, food will easily be blocked. If the length of the blanking channel is too short, the cutting section will easily push the food upward during the rotational motion. Summary of the Invention

[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0031] See also Figures 1 to 4The present invention relates to a horizontal juicer, comprising: a juice cup 100, wherein the juice cup 100 has a feed channel 110 extending in the vertical direction and a juice extraction channel 120 extending in the horizontal direction, one side of the bottom of the feed channel 110 is connected to the upper side of the juice extraction channel 120 through a drop channel 130, an impeller assembly 200 is rotatably arranged in the feed channel 110, and the rotating shaft of the impeller assembly 200 is arranged in the vertical direction, and a blade portion 140 that cooperates with the impeller assembly 200 is provided on the contour edge of the upper port of the drop channel 130 on the bottom surface of the feed channel 110, and a blade portion 140 that cooperates with the impeller assembly 200 is provided in the juice extraction channel 120. A screw propeller 300 is provided, and the rotating shaft of the screw propeller 300 is arranged along the central axis of the juicing channel 120 and is orthogonal to the rotating shaft of the impeller assembly 200. The impeller assembly 200 and the screw propeller 300 are both connected to the rotation drive device 400 to achieve synchronous rotation. The screw propeller 300 includes a rotating body 310 and a spiral cutting segment 320 formed on the outer peripheral wall of the rotating body 310. The dimension of the spiral cutting segment 320 radially protruding from the outer peripheral wall of the rotating body 310 is A, and the maximum height dimension of the blanking channel 130 is B, satisfying: 2A≤B≤3A, 10mm≤A≤18mm.

[0032] The inlet of the feeding channel 130 occupies a portion of the bottom surface of the feeding channel 110. In this embodiment, the cross-section of the feeding channel 130 is generally rectangular. The cross-section of the feeding channel 130, along a radial direction parallel to the screw propeller 300, is close to the outer diameter of the screw propeller 300, thereby preventing food from clogging. Preferably, the cross-section of the feeding channel 130 has a length of 40 mm to 50 mm and a width of 30 mm to 40 mm. The maximum outer diameter of the screw propeller 300 is 48 mm to 58 mm. When the above horizontal juicer is working, the rotary drive device 400 drives the impeller assembly 200 and the spiral propeller 300 to rotate synchronously. The impeller assembly 200 intermittently passes through the blade portion 140 to interrupt or crush the food at the bottom of the feed channel 110, and the chopped food enters the feeding channel 130. When the height of the feeding channel 130 meets the above conditions, the feeding channel 130 will not be blocked by the food being too long, nor will the spiral cutting section 320 push the food back into the feeding channel 110 because the feeding channel 130 is too short. The food enters the juicing channel 120 and is further broken and ground by the spiral propeller 300. The rotating shaft of the impeller assembly 200 and the rotating shaft of the spiral propeller 300 are orthogonal, which alleviates or avoids the problem that the food is entangled on the spiral propeller 300 and cannot be broken, which is conducive to crushing the food to improve the juice yield, and the food is not easily blocked when it is input into the juicing channel 120.

[0033] See also Figure 2In some embodiments of the present invention, the rotating shaft of the impeller assembly 200 is a first drive shaft 201, and the rotating shaft of the propeller 300 is a second drive shaft 301. The first drive shaft 201 is located directly above the second drive shaft 301, and the axial direction of the first drive shaft 201 extends radially toward the second drive shaft 301. The rotation drive device 400 includes a first bevel gear 410 connected to the lower end of the first drive shaft 201. The second drive shaft 301 is provided with a second bevel gear 420 that meshes with the first bevel gear 410. The second drive shaft 301 is connected to a rotation driver 430 for driving the second drive shaft 301 to rotate. It will be understood that when the rotation driver 430 drives the second drive shaft 301 to rotate, the second bevel gear 420 drives the first drive shaft 201 on the first bevel gear 410 to rotate, thereby driving the propeller 300 and the impeller assembly 200 to rotate simultaneously, which is beneficial for reducing costs and improving structural compactness. Furthermore, the impeller assembly 200 is driven by the first bevel gear 410, the second bevel gear 420, and the rotary driver 430 below. This eliminates the need to occupy space in the feed channel 110 and prevents the impeller assembly 200 from breaking up the food. Specifically, the rotary driver 430 comprises a motor coupled with a worm gear mechanism. The motor's output shaft points vertically upward, directly driving the worm, which in turn rotates the second drive shaft 301 on the worm gear. This ensures that the juicer's axial length along the second drive shaft 301 is not increased, preventing it from occupying a large area when placed on a table.

[0034] See also Figures 2 to 4In some embodiments of the present invention, the juice cup 100 has a cover body 500 that blocks the upper port of the feed channel 110. The impeller assembly 200 includes a rotating rod 210, a cutting blade 220, and a transmission head 230. The inner surface of the cover body 500 is provided with a first axial hole for rotatably connecting the upper end of the rotating rod 210. The lower end of the rotating rod 210 is provided with a threaded hole 211 extending along its length and a square groove 212 located on the outer periphery of the threaded hole 211. The middle portion of the cutting blade 220 is provided with a square through hole 221 opposite to the square groove 212. The transmission head 230 includes a square cap body 231 and a groove formed on the square cap body. 231, a flange portion 232 is provided on the outer peripheral edge of the square cap body 231, and a through hole portion is provided in the middle of the square cap body 231 opposite to the threaded hole 211. The square cap body 231 is passed through the square through hole 221 to be embedded in the square sink 212. The cutting blade 220 is clamped between the flange portion 232 and the lower end of the rotating rod 210. The bolt fastener is passed through the through hole portion and is connected to the threaded hole 211. The bottom of the feed channel 110 is rotatably provided with a joint member 600. The upper part of the joint member 600 is provided with a square rod portion inserted in the square cap body 231, and the lower part of the joint member 600 is connected to the upper end of the first drive shaft 201. It can be understood that when assembling the impeller assembly 200, the square cap body 231 of the transmission head 230 is passed through the square through hole 221 and then inserted into the square recess 212, and then a bolt fastener is used to pass through the through hole portion to connect the threaded hole 211, thereby fixing the rotating rod 210, the cutting blade 220 and the transmission head 230 together, and the rotating rod 210, the cutting blade 220 and the transmission head 230 cannot rotate relative to each other, and the square cap body 231 is detachably plugged into the square rod portion of the joint member 600. When the first drive shaft 201 drives the joint member 600 to rotate, the joint member 600 drives the square cap body 231 to rotate, thereby driving the rotating rod 210 and the cutting blade 220 to rotate around the axial direction of the first drive shaft 201. Moreover, the impeller assembly 200 with the above structure makes the cutting blade 220 almost located at the lower end of the rotating rod 210, which is conducive to the rotating rod 210 being close to the bottom surface of the feed channel 110 and the blade portion 140, which helps to break or crush the food.

[0035] See also Figure 2 and Figure 4In some embodiments of the present invention, in order to prevent the connecting member 600 from being pulled out when the transmission head 230 is pulled out from the connecting member 600, the outer periphery of the connecting member 600 is in the shape of a truncated cone with a small top and a large bottom. The juicer cup 100 is provided with a corresponding truncated cone hole at the bottom of the feed channel 110. The lower end surface of the connecting member 600 is provided with a fixed disk 610, and the lower end surface of the fixed disk 610 is provided with a friction plate 620. The upper end of the first drive shaft 201 is provided with a movable disk 63 that can only move up and down relative to the first drive shaft. 0, the first drive shaft 201 is threadedly connected to a circular base plate 640 located below the movable disk 630, and a plurality of compression springs 650 are provided between the circular base plate 640 and the movable disk 630, which are circumferentially distributed and axially spaced around the first drive shaft 201. The compression springs 650 drive the movable disk 630 to rest against the friction plate 620, and the circular base plate 640 can spirally feed relative to the first drive shaft 201 to adjust the compression amount of the compression springs 650. It should be noted that since a rotary drive device 400 drives the impeller assembly 200 and the screw propeller 300 to rotate at the same time, the power of the rotary drive device 400 is limited, and the torque transmitted to the impeller assembly 200 is also relatively limited. When the volume of the food to be crushed is too large, the hardness is too hard, or the density of the food accumulation is too high, it is easy to cause the impeller assembly 200 to get stuck and burn the motor of the rotary drive device 400. The first drive shaft 201 and the joint member 600 of the above structure use friction to transmit torque, and the movable disk 630 is pressed against the friction plate 620 by multiple compression springs 650. When the torque transmitted to the impeller assembly 200 by the first drive shaft 201 is not enough to crush or cut the food, the fixed disk 610 can rotate relative to the movable disk 630, that is, the first drive shaft 201 rotates relative to the joint member 600 to avoid getting stuck and causing the motor to overheat. In addition, the user can also adjust the friction between the first drive shaft 201 and the connector 600 according to the maximum torque that the motor can withstand and is allocated to the impeller assembly 200, simply by screwing the annular base plate 640 to feed the first drive shaft 201.

[0036] See also Figure 3In some embodiments of the present invention, the bottom surface of the feed channel 110 is recessed downward and provided with an arcuate guide ramp 150 that communicates with the upper end of the feeding channel 130. The arcuate guide ramp 150 is disposed around the rotation axis of the impeller assembly 200, and the depth of the arcuate guide ramp 150 gradually increases clockwise as the impeller assembly 200 rotates, reaching a maximum depth at the junction of the arcuate guide ramp 150 and the feeding channel 130. It will be appreciated that as the impeller assembly 200 rotates in a predetermined clockwise direction, the cut or chopped food moves along the high slope of the arcuate guide ramp 150 toward the low slope. During this process, the food gradually moves closer to the upper end of the feeding channel 130 and smoothly falls into the feeding channel 130.

[0037] It should be noted that the spiral cutting section 320 is likely to push the food upwards during the rotational motion, causing the food to move upwards and become turbulent when falling down the feeding channel 130 into the juicing channel 120, thereby affecting the uniformity of the food supply to the screw propeller 300. Figure 2 and Figure 4 In some embodiments of the present invention, the inner circumferential wall of the blanking channel 130 is provided with a plurality of limiting guide mechanisms 700 extending along the height direction of the blanking channel 130, and the limiting guide mechanism 700 includes a strip mounting seat 710 fixed to the inner wall of the blanking channel 130, and the strip mounting seat 710 is provided with a plurality of sliding channels 720 at intervals along its length direction, and the sliding channel 720 has an opening toward the middle of the blanking channel 130, and a wedge block 730 is slidably provided in the sliding channel 720, and the wedge block 730 is connected to an elastic member 740 that drives it to extend a certain distance from the opening of the sliding channel 720, and the wedge block 730 has a guiding inclined surface 750 inclined from top to bottom toward the middle of the blanking channel 130. It is understood that, under the action of the elastic member 740, the guide slope 750 of each wedge block 730 extends toward the center of the feeding channel 130. When food rests against the guide slope 750 and moves downward, the wedge block 730 is forced to fully retract into the sliding channel 720 in the direction of the compressed elastic member 740. After the food passes over the wedge block 730, the wedge block 730, under the action of the elastic member 740, extends back toward the center of the feeding channel 130. When the spiral cutting segment 320 pushes the food upward during its rotational motion, the lower end surface of the wedge block 730 prevents the food directly below from jumping upward, thereby providing a unidirectional guide for the food to flow downward. In this embodiment, the feeding channel 130 has a rectangular cross-section, and each of the four inner circumferential walls of the feeding channel 130 is provided with a limiting guide mechanism 700. Of course, in other embodiments, the feeding channel 130 may have other cross-sectional shapes, and the limiting guide mechanism 700 may be assembled in the corresponding position according to actual needs.

[0038] In addition, it should be noted that the slight protrusion of the strip mounting seat 710 from the inner wall of the material drop channel 130 will not affect the food sliding down along the inner wall of the material drop channel 130. If in some embodiments you want to avoid the problem of the strip mounting seat 710 protruding from the inner wall of the material drop channel 130, you can also set a corresponding strip sinking groove on the inner wall of the material drop channel 130. At this time, only the wedge block 730 can protrude from the inner wall of the material drop channel 130.

[0039] See also Figure 4 In some embodiments of the present invention, in order to prevent the wedge block 730 from completely detaching from the strip mounting seat 710 when extending relative to the sliding channel 720, an anti-detachment cap 760 is installed at the end of the sliding channel 720. The anti-detachment cap 760 is provided with a perforation along the extension direction of the sliding channel 720, and the end of the wedge block 730 away from the guide slope 750 is provided with an anti-detachment flange 770 that matches the anti-detachment cap 760.

[0040] See also Figure 5 In some embodiments of the present invention, the first drive shaft 201 is connected to a third drive shaft 810 parallel to the second drive shaft 301 and passing through the side wall of the blanking channel 130 through a bevel gear set. The third drive shaft 810 passes through one end of the blanking channel 130 and is connected to a first crank member 820 and a second crank member 830 arranged at intervals. The inner circumferential wall of the blanking channel 130 is provided with a sliding bracket 840 opposite to the first crank member 820 for sliding in the vertical direction. The sliding bracket 840 is connected to a first spring member 850 that drives it to move upward. A lifting block 860 opposite to the second crank member 830 is slidably provided on the sliding bracket 840. The lifting block 860 is connected to a driving The second spring member 870 moves upward relative to the sliding bracket 840, and the lifting block 860 has a driving inclined surface 861 inclined from bottom to top toward the middle of the blanking channel 130. The sliding bracket 840 is provided with a guide channel 841 toward the middle of the blanking channel 130. The guide channel 841 is slidably provided with a side extension block 880 that can be telescopically moved relative to it, and the side extension block 880 is maintained against the driving inclined surface 861; when the third drive shaft 810 rotates, the first crank member 820 drives the sliding bracket 840 to move back and forth relative to the blanking channel 130, and the second crank member 830 drives the lifting block 860 to move back and forth relative to the sliding bracket 840.

[0041] It can be understood that, through the above structure, when the rotary driver 430 rotates, it can simultaneously drive the first drive shaft 201, the second drive shaft 301 and the third drive shaft 810 to rotate, which is beneficial to reducing costs and improving the compactness of the structure. Specifically, the first crank member 820 and the second crank member 830 are the first cam and the second cam respectively. When the third drive shaft 810 drives the first cam to gradually rotate to the distal end and abut against the sliding bracket 840, the sliding bracket 840 slides downward to compress the first spring member 850. During this process, the second cam gradually rotates to the distal end and abuts against the lifting block 860. The lifting block 860 slides downward relative to the sliding bracket 840 to compress the second spring member 870. When the driving inclined surface 861 moves downward, it pushes the side extension block 880 to extend outward. That is, when the sliding bracket 840 and the lifting block 860 descend together, the side extension block 880 extends outward to push the food downward, which helps to push the food to the juicer. In the channel 120, when the third driving shaft 810 drives the first cam to gradually rotate to the proximal end and abut against the sliding bracket 840, the first spring member 850 drives the sliding bracket 840 to slide upward. During this process, the second cam gradually rotates to the proximal end and abuts against the lifting block 860. The second spring member 870 drives the lifting block 860 to rise relative to the sliding bracket 840, and the driving inclined surface 861 moves upward to make the side extension block 880 retract inward. That is, in the process of the sliding bracket 840 and the lifting block 860 rising together, the side extension block 880 retracts inward to avoid or reduce the lifting of food upward. Therefore, in the process of the sliding bracket 840 reciprocating up and down, the function of intermittently pushing food downward can be achieved.

[0042] It should be noted that in order to prevent the first crank member 820, the second crank member 830, the sliding bracket 840, the lifting block 860 and other components from protruding from the side wall of the material drop channel 130 and affecting the effect of intermittently pushing the food downward, in some embodiments, the inner wall of the material drop channel 130 is provided with a movable sinking cavity for accommodating the first crank member 820, the second crank member 830, the sliding bracket 840, and the lifting block 860. At this time, only the side extension block 880 can protrude from the inner wall of the material drop channel 130.

[0043] In addition, when the rotary driver 430 drives the second drive shaft 301 to rotate, the second bevel gear 420 drives the first drive shaft 201 on the first bevel gear 410 to rotate, thereby driving the propeller 300 and the impeller assembly 200 to rotate at the same time, which is beneficial to reducing costs and improving structural compactness.

[0044] See also Figure 5861 , the lifting block 860 is lifted and lowered to move in a reciprocating manner, so that the lifting block 860 can be lifted and lowered to move in a reciprocating manner relative to the guide channel 841. Of course, in other embodiments, a spring may be used to drive the side extension block 880 to remain against the driving inclined surface 861 .

[0045] See also Figure 6 In some embodiments of the present invention, the first drive shaft 201 is connected to a third drive shaft 810 parallel to the second drive shaft 301 through a bevel gear set, and the end of the third drive shaft 810 away from the first drive shaft 201 is penetrated by the side wall of the blanking channel 130 and is connected to an eccentric wheel 910, and the inner peripheral wall of the blanking channel 130 is provided with a serrated bar 920 opposite to the eccentric wheel 910 for sliding in the vertical direction, and the serrated bar 920 is connected to a third spring member 930 that drives it upward to press against the eccentric wheel 910, and when the first drive shaft 201 rotates, the third drive shaft 810 is linked to the rotation through the bevel gear set to rotate the eccentric wheel 910, and the distal end of the eccentric wheel 910 presses against the upper end of the serrated bar 920 to drive the serrated bar 920 to slide downward. It should be noted that for some foods with high density and viscosity that are easily attached to the inner wall of the feeding channel 130, the reciprocating movement of the sawtooth bar 920 can prevent the foods from adhering to the inner wall of the feeding channel 130, thereby improving the smoothness of food feeding and helping to reduce the load on the screw propeller 300 when cutting and grinding the foods, further improving the juice extraction efficiency. Specifically, when the first drive shaft 201 rotates, the third drive shaft 810 is linked to rotate by the bevel gear set to rotate the eccentric wheel 910. The distal end of the eccentric wheel 910 abuts against the upper end of the sawtooth bar 920 to drive the sawtooth bar 920 to slide downward. When the eccentric wheel 910 rotates to the point where the proximal end is facing the upper end of the sawtooth bar 920, under the action of the third spring member 930, the upper end of the sawtooth bar 920 abuts against the proximal end of the eccentric wheel 910, thereby achieving the reciprocating lifting and lowering movement of the sawtooth bar 920. No additional drive source is required, and the structure is very ingenious.
