Description

Technical Field

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

[0002] Generally, juicers are divided into two types of layouts: horizontal and vertical. Both types of juicers include a juice cup, a screw propeller that rotates inside the juice cup, and a motor that drives the screw propeller to rotate. Among them, the juice cup and the screw propeller of the horizontal juicer are placed horizontally, and the upper side wall of the juice cup has an opening for feeding fruits or vegetables. The cutting section of the screw propeller cooperates with the inner wall of the juice cup to crush the fruits or vegetables, and then the juice and residue are 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 fibers, if the long strip food materials are not cut into multiple sections in advance, they are easily entangled on the cutting section of the screw propeller, affecting the juice yield.

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

[0031] See also Figures 1 to 4The present invention provides a horizontal juicer, comprising: a juice cup 100, wherein the juice cup 100 has a feed channel 110 extending in a vertical direction and a juice extraction channel 120 extending in a horizontal direction, wherein 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, wherein an impeller assembly 200 is rotatably arranged in the feed channel 110, wherein the rotating shaft of the impeller assembly 200 is arranged in a vertical direction, wherein a blade portion 140 matching with the impeller assembly 200 is arranged at the contour edge of the upper port of the drop channel 130 on the bottom surface of the feed channel 110, wherein the impeller assembly 200 is rotatably arranged in the juice extraction channel 120, wherein the impeller assembly 200 is rotatably arranged in the feed channel 110, wherein the impeller assembly 200 is rotatably arranged in the feed channel 110, wherein the impeller assembly 200 is rotatably arranged in the feed channel 12 ...10, wherein the impeller assembly 200 is rotatably arranged in the feed channel 120, wherein the impeller assembly 200 is rotatably arranged in the feed channel 110, wherein the impeller assembly 200 is rot A screw propeller 300 is provided, and the rotating shaft of the screw propeller 300 is arranged along the central axis of the juice extraction 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 rotary drive device 400 to realize 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, which satisfies: 2A≤B≤3A, 10mm≤A≤18mm.

[0032] The inlet of the material drop channel 130 occupies a part of the bottom surface of the feed channel 110. In this embodiment, the cross-sectional shape of the material drop channel 130 is roughly rectangular, and the cross-sectional shape of the material drop channel 130 along the radial direction parallel to the screw propeller 300 is close to the outer diameter of the screw propeller 300, so as to ensure that the food is not easily blocked. Preferably, the cross-sectional shape of the material drop channel 130 has a length dimension of 40mm to 50mm, a width dimension of 30mm to 40mm, and a maximum outer diameter dimension of the screw propeller 300 is 48mm to 58mm. When the above horizontal juicer is working, the rotary drive device 400 drives the impeller assembly 200 and the screw propeller 300 to rotate synchronously, and 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 drop channel 130. When the height dimension of the drop channel 130 meets the above conditions, the drop channel 130 will not be blocked by the food due to being too long, nor will the spiral cutting section 320 push the food back into the feed channel 110 due to being too short. The food enters the juicing channel 120 and is further broken and ground by the screw propeller 300. The rotating shaft of the impeller assembly 200 and the rotating shaft of the screw propeller 300 are orthogonal, which alleviates or avoids the problem that the food is entangled on the screw 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 the first drive shaft 201, the rotating shaft of the screw propeller 300 is the second drive shaft 301, the first drive shaft 201 is located directly above the second drive shaft 301, the axial direction of the first drive shaft 201 is extended 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 meshing with the first bevel gear 410, and the second drive shaft 301 is connected to a rotation driver 430 driving it to rotate. It can 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 screw propeller 300 and the impeller assembly 200 to rotate at the same time, which is conducive to reducing costs and improving structural compactness. Moreover, the impeller assembly 200 is driven by the first bevel gear 410, the second bevel gear 420 and the rotary driver 430 below, and does not occupy the space of the feed channel 110, and does not affect the crushing of the food by the impeller assembly 200. Specifically, the rotary driver 430 is a motor in combination with a worm gear mechanism, and the output shaft of the motor is vertically upward to directly drive the worm member to rotate, and the worm member is linked to the second drive shaft 301 on the worm gear member to rotate, that is, the length dimension of the juicer along the axial direction of the second drive shaft 301 is not increased, and it is avoided that it occupies a large area when placed on the desktop.

[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 the upper end of the rotating rod 210 to be rotatably connected, the lower end of the rotating rod 210 is provided with a threaded hole 211 extending along its length direction and a square groove 212 located on the outer periphery of the threaded hole 211, the middle part 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 The flange portion 232 is on the outer peripheral edge of 231, and the middle part of the square cap body 231 is provided with a through hole portion opposite to the threaded hole 211. The square cap body 231 is penetrated 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 penetrated through the through hole portion and 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 to connect the threaded hole 211, so as to fix 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 transmission head 230 from pulling out the connector 600, the outer peripheral contour of the connector 600 is a truncated cone with a small top and a large bottom. The juice extraction cup 100 is provided with a truncated cone hole corresponding to the bottom of the feed channel 110. The lower end surface of the connector 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 driving shaft 201 is provided with a movable disk 630 that can only be lifted and moved relative to the first driving shaft 201. 0, the first drive shaft 201 is threadedly connected with a circular base plate 640 located below the movable disk 630, and a plurality of compression springs 650 are arranged between the circular base plate 640 and the movable disk 630 and are circumferentially distributed at axial intervals around the first drive shaft 201. The compression springs 650 drive the movable disk 630 to press against the friction plate 620, and the circular base plate 640 can move in a spiral 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 large, 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 overheating of the motor. In addition, the user can also adjust the friction between the first drive shaft 201 and the joint member 600 according to the maximum torque that the motor can withstand and is allocated to the impeller assembly 200 , and only needs to screw 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 arc guide slope 150 connected to the upper end of the drop channel 130. The arc guide slope 150 is arranged around the rotating shaft of the impeller assembly 200, and the depth dimension of the arc guide slope 150 gradually deepens in the clockwise direction of the operation of the impeller assembly 200, and the depth dimension of the connection between the arc guide slope 150 and the drop channel 130 is the maximum value. It can be understood that when the impeller assembly 200 rotates in the preset clockwise direction, the cut or broken food can move along the high slope position of the arc guide slope 150 toward the low slope position. In this process, the food gradually moves closer to the upper end of the drop channel 130 to smoothly fall into the drop 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 material channel 130 into the juice extraction channel 120, thus affecting the uniformity of the food supply to the spiral propeller 300. Figure 2 and Figure 4 In some embodiments of the present invention, the inner circumferential wall of the blanking channel 130 is spaced apart with a plurality of limiting guide mechanisms 700 extending along the height direction of the blanking channel 130, the limiting guide mechanism 700 includes a strip mounting seat 710 fixed to the inner wall of the blanking channel 130, the strip mounting seat 710 is spaced apart with a plurality of sliding channels 720 along its length direction, the sliding channel 720 has an opening toward the middle of the blanking channel 130, a wedge block 730 is slidably arranged in the sliding channel 720, the wedge block 730 is connected to an elastic member 740 driving it to extend a certain distance from the opening of the sliding channel 720, the wedge block 730 has a guiding inclined surface 750 inclined from top to bottom toward the middle of the blanking channel 130. It can be understood that under the action of the elastic member 740, the guide slope 750 of each wedge block 730 extends toward the middle of the material drop channel 130. When the food rests against the guide slope 750 and moves downward, the wedge block 730 is forced to completely retract into the sliding channel 720 in the direction of compressing the elastic member 740. After the food passes over the wedge block 730, the wedge block 730 extends toward the middle of the material drop channel 130 again under the action of the elastic member 740. When the spiral cutting section 320 pushes the food upward during the rotational motion, the lower end surface of the wedge block 730 can prevent the food directly below from jumping upward, thereby playing the function of guiding the food to flow downward in a unidirectional manner. In this embodiment, the cross section of the material drop channel 130 is rectangular, and each of the four inner peripheral walls of the material drop channel 130 is provided with a limiting guide mechanism 700. Of course, in other embodiments, the cross section of the material drop channel 130 can also be other shapes, and the limiting guide mechanism 700 can also be assembled at 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, it is desired to avoid the problem of the strip mounting seat 710 protruding from the inner wall of the material drop channel 130, a corresponding strip groove can also be provided on the inner wall of the material drop channel 130. In this case, 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, and 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 matching 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 penetrating the side wall of the blanking channel 130 through a bevel gear set. The third drive shaft 810 is penetrating the blanking channel 130 and is connected to a first crank member 820 and a second crank member 830 arranged at intervals at one end. The inner circumferential wall of the blanking channel 130 is provided with a sliding bracket 840 opposite to the first crank member 820 in a 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, and 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 driving 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 conducive 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 until the distal end abuts 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 until the distal end 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, in the process of the sliding bracket 840 and the lifting block 860 descending 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 delivery channel 130 and affecting the effect of intermittently pushing the food downward, in some embodiments, the inner wall of the material delivery channel 130 is provided with a movable sink 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 delivery 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 simultaneously, which is beneficial to reducing costs and improving structural compactness.

[0044] See also Figure 5In some embodiments of the present invention, in order to ensure that the side extension block 880 can remain against the driving inclined surface 861 so that the lifting block 860 can drive the side extension block 880 to move telescopically relative to the guide channel 841 when the lifting block 860 moves up and down, the side extension block 880 and the lifting block 860 are both made of magnetic materials, and the side extension block 880 and the lifting block 860 attract each other so that the side extension block 880 remains against the driving inclined surface 861. The upper part of the lifting block 860 is provided with a bolt member 862 that passes upward through the sliding bracket 840, and the second spring member 870 passes through the bolt member 862 and rests between the head of the bolt member 862 and the sliding bracket 840. In order to improve the smoothness of the second crank member 830 driving the lifting block 860 to move, the head of the bolt member 862 is provided with a roller member 863 that elastically rests against the second crank member 830. 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 one end of the third drive shaft 810 away from the first drive shaft 201 is penetrated through the side wall of the blanking channel 130 and is connected to an eccentric wheel 910, and the inner circumferential wall of the blanking channel 130 is provided with a sawtooth bar 920 opposite to the eccentric wheel 910 in a sliding manner in the vertical direction, and the sawtooth bar 920 is connected to a third spring member 930 that drives it to press upward against the eccentric wheel 910, and when the first drive shaft 201 rotates, the third drive shaft 810 is linked to rotate 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 sawtooth bar 920 to drive the sawtooth bar 920 to slide downward. It should be noted that for some food materials with high density, high viscosity, and easy to adhere to the inner wall of the material drop channel 130, the reciprocating up and down movement of the sawtooth bar 920 can prevent the food materials from adhering to the inner wall of the material drop channel 130, improve the smoothness of the food drop, and also help reduce the load of the spiral propeller 300 when cutting and grinding the food materials, further improving the juice extraction efficiency. Specifically, when the first drive shaft 201 rotates, the third drive shaft 810 is linked to rotate through the bevel gear group to rotate the eccentric wheel 910, and 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 realizing the reciprocating lifting and lowering movement of the sawtooth bar 920, and no additional drive source is required, and the structure is very ingenious.
