Further, the preset angle β is greater than or equal to 75° and smaller than or equal to 120°, and In one embodiment, as shown in FIG. 1, the preset angle β is equal to 90°, i.e., the first drive shaft 213 and the second drive shaft 215 are arranged to be perpendicular to each other.

(19) In one embodiment, the rotational speed ratio between the first drive shaft 213 and the second drive shaft 215 is A, wherein the value of the rotational speed ratio A is more than or equal to ⅔ and less than or equal to 3.

(20) In one embodiment, the rotational speed ratio between the first drive shaft 213 and the second drive shaft 215 can be reasonably controlled by reasonably selecting the parameters of the first transmission member 212 and the second transmission member 214, so that the rotational speed ratio between the first drive shaft 213 and the second drive shaft 215 can be adapted to specific application occasions.

(21) In one embodiment, the rotational speed ratio is 1.

(22) In one embodiment, the first drive shaft 213 and the second drive shaft 215 rotate in the same direction or in opposite directions.

(23) In one embodiment, the first drive shaft 213 and the second drive shaft 215 can rotate in the same direction, for example, both rotate clockwise or both rotate anticlockwise; and of course, the first drive shaft 213 and the second drive shaft 215 can also rotate oppositely, in one embodiment, for example, one rotates clockwise and the other rotates anticlockwise.

(24) In one embodiment, the first transmission member 212 and the second transmission member 214 are bevel gears that are meshed with each other; or the first transmission member 212 is a turbine, and the second transmission member 214 is a worm; or the first transmission member 212 and the second transmission member 214 are two helical gears whose shafts are arranged in a staggered manner.

(26) In one embodiment, as shown in FIG. 1, the transmission assembly further comprises: a housing comprising an upper housing 217 and a lower housing 216 that are assembled, the upper housing 217 and the lower housing 216 defining an installation cavity, the first transmission member 212 and the second transmission member 214 being positioned in the installation cavity, and the first drive shaft 213 and the second drive shaft 215 extending out of the housing.

(27) In one embodiment, the first transmission member 212 and the second transmission member 214, and the first drive shaft 213 and the second drive shaft 215 can be installed in the housing, so that when in specific use, the transmission assembly can be moved and replaced as a whole.

(28) In one embodiment, as shown in FIG. 1, the transmission assembly further comprises a deceleration assembly 218 arranged between the first transmission member 212 and the motor shaft for reducing the rotational speed of the motor shaft to a desired rotational speed of the first drive shaft 213 and the second drive shaft 215.

(29) In another technical solution (not shown in the figures), the drive body is an electrified coil, the first transmission member 212 and the second transmission member 214 are both magnetically conducting disc bodies that rotate under a magnetic field generated by the electrified coil.

(30) In one embodiment, the multi-shaft and multi-angle output can be realized by using the principle of solenoid drive. In one embodiment, for example, a magnetic field can be generated by using the electrified coil, and then the magnetically conducting disc bodies are driven to rotate by using the interaction between the magnetic property of the magnetically conducting disc bodies and the magnetic field of the electrified coil, so that the rotation of the magnetically conducting disc bodies can drive the first drive shaft 213 and the second drive shaft 215 to rotate, thereby achieving the multi-shaft and multi-angle output of the drive assembly 21.

(31) In one embodiment, the magnetically conducting disc body comprises a disc body and a plurality of magnetically conducting bodies distributed in the circumferential direction of the disc body, wherein the magnetically conducting body is preferably a magnet.

(32) As shown in FIGS. 2-4, an embodiment of the present disclosure provides a food processor comprising a drive assembly 21 in any of the above technical solutions.

(33) The food processor according to the embodiment of the present disclosure comprises a drive assembly 21 provided in any of the embodiments of the present disclosure, and therefore the food processor has all the beneficial effects of the drive assembly 21 provided in any of the above embodiments.

(34) In one embodiment, as shown in FIGS. 2-4, the food processor further comprises: a host assembly 2 comprising a drive assembly 21; a barrel body assembly installed on the host assembly 2 and comprising a feed inlet; a first barrel body 11 communicating with the feed inlet; and a second barrel body 12 communicating with the first barrel body 11 through a communication port; a smashing device 13 that is arranged in the first barrel body 11, is in driving connection with the first drive shaft 213 and is rotated under the driving of the first drive shaft 213; and a squeezing device 14 that is arranged in the second barrel body 12, is in driving connection with the second drive shaft 215 and is rotated under the driving of the second drive shaft 215, wherein when rotating, the smashing device 13 is capable of cooperating with an inner side wall of the first barrel body 11 to smash food entering the first barrel body 11 from the feed inlet, and the smashed food enters, under the effect of the smashing device 13, the second barrel body 12 through the communication port and is squeezed by the squeezing device 14 in the second barrel body 12 to achieve separation between juice and food residues.

(35) In one embodiment, food enters the first barrel body 11 from the feed inlet and is then smashed by the smashing device 13 matched with the side wall of the first barrel body 11, and the smashed food enters, under the effect of the smashing device 13, the second barrel body 12 from the communication port, and is then squeezed by the squeezing device 14 to achieve separation between juice and food residues. In one embodiment, the smashing process of the food is separated from the squeezing and residue discharging process, in the smashing process, since squeezing and residue discharging are not required, there is no need to arrange the components such as a filter screen and a rotary brush in the first barrel body 11, so that the food in the first barrel body 11 can be smashed under the combined effect of the first barrel body 11 and the smashing device 13, and in the squeezing and residue discharging process, the squeezing device 14 can be substantially horizontally arranged, i.e., the squeezing and residue discharging system can be arranged to be horizontal, which thereby makes it very convenient to separate juice from food residues. Such configuration can, on the one hand, ensure the juice yield of the food processor, and on the other hand, avoid the use of the parts such as a filter screen and a rotary brush, which thereby makes the food processor simple in structure and easy to install; furthermore, since the filter screen is omitted, it is possible to reduce the cleaning difficulty for the user, which thereby improves the user experience. In one embodiment, it is feasible to drive the smashing device 13 by means of the first drive shaft 213 of the drive assembly 21 to smash the food, and drive the squeezing device 14 by means of the second drive shaft 215 of the drive assembly 21 to squeeze the food so as to achieve separation between juice and food residues.

(36) In one embodiment, as shown in FIGS. 2-4, the feed inlet is located at an upper end of the first barrel body 11, the communication port is located at a lower end of the first barrel body 11, the second barrel body 12 is installed on a side wall of the first barrel body 11, and the first barrel body 11 is arranged to be vertical.

(37) In one embodiment, as shown in FIGS. 2-4, the food processor further comprises: a juice discharge opening 121 arranged on the second barrel body 12, wherein after the separation between juice and food residues, the food juice is discharged through the juice discharge opening 121; and a residue discharge opening 122 arranged on the second barrel body 12, wherein after the separation between juice and food residues, the food residues are discharged through the residue discharge opening 122.

(38) In one embodiment, after the pulverized food enters the second barrel body 12, juice is separated from the food residues under the squeezing effect of the squeezing device 14, the separated food juice is discharged from the juice discharge opening 121 in the second barrel body 12, and the separated food residues are discharged from the residue discharge opening 122 in the second barrel body 12.

(39) In one embodiment, as shown in FIGS. 2-4, a filter sheet 15 is arranged at the juice discharge opening 121.

(40) In one embodiment, by arranging a filter sheet 15, the food residues can be prevented from being discharged from the juice discharge opening 121. Moreover, the distance between the filter sheet 15 and the squeezing device 14 can be reasonably set in accordance with the particle size of the food residues, so that automatic cleaning of the filter sheet 15 can be realized by utilizing the friction between the squeezing device 14 and the filter sheet 15.

(41) In one embodiment, the filter sheet 15 is a metal filter sheet. Since a metal filter sheet has relatively high hardness and wear resistance, at the time of cleaning the filter sheet 15 by utilizing the squeezing device 14, it is possible to prevent the occurrence of the case where the filter screen is damaged due to insufficient strength.

(42) In one embodiment, as shown in FIGS. 2-4, a squeezing rubber sheet 16 is arranged at the residue discharge opening 122.

(43) In one embodiment, by arranging a squeezing rubber sheet 16 at the residue discharge opening 122, it is possible to further squeeze the food, so as to enable more thorough separation between juice and food residues, so that more food juice can be squeezed out, which can thereby improve the juice yield of the food processor.

(44) In one embodiment, as shown in FIG. 2, the smashing device 13 is a grinding spiral head, or as shown in FIGS. 3 and 4, the smashing device 13 is a cutter, and as shown in FIGS. 2-4, the squeezing device 14 is a squeezing screw rod.

(45) In one embodiment, the smashing of the food and the pushing of the food into the second barrel body 12 can be realized by using a grinding spiral head or a cutter, and the squeezing and residue discharging can be realized by using a squeezing screw rod.

(46) In one embodiment, as shown in FIG. 2, when the smashing device 13 is a grinding spiral head, a groove or a convex rib is arranged on the inner side wall of the first barrel body 11 in the axial direction. By arranging a groove or a convex rib on the inner side wall of the first barrel body 11, the friction between the food and the side wall of the first barrel body 11 can be increased, so that under the effect of the grinding spiral head, greater friction can be generated between the food and the side wall of the first barrel body 11, which thereby can smash the food into smaller pieces in the first barrel body 11, and further enable more thorough separation between juice and food residues after the food enters the second barrel body 12, thereby improving the juice yield.

(47) In one embodiment, as shown in FIG. 2, when the smashing device 13 is a grinding spiral head, a preset gap a is formed between the inner side wall of the first barrel body 11 and the grinding spiral head, and the value of the preset gap a is 0.8 mm≤a≤4 mm.

(48) In one embodiment, a preset gap a is formed between the inner side wall of the first barrel body 11 and the grinding spiral head, the food entering the first barrel body 11 is located in the preset gap and is pulverized under the combined effect of the first barrel body 11 and the grinding spiral head, the pulverized food is pushed to the communication port along the grinding spiral head under the guide of the grinding spiral head and enters the second barrel body 12 through the communication port.

(49) In one embodiment, as shown in FIGS. 3 and 4, when the smashing device 13 is a cutter, at least one blocking rib 111 is arranged on the inner side wall of the first barrel body 11, the blocking rib 111 cooperates with the cutter, so as to cut the food entering the first barrel body 11 from the feed inlet. In one embodiment, the food can be cut into smaller pieces by the cooperation of the blocking rib 111 arranged on the inner side wall of the first barrel body 11 with the cutter. In one embodiment, for example, the blocking rib 111 can block the movement of the food when the cutter cuts the food, so that the cutter can hit the food exactly, so as to cut the food into smaller pieces, and cutting the food into smaller pieces enables the squeezing of more food juice, which thereby can improve the juice yield of the food.

(50) In one embodiment, as shown in FIGS. 3 and 4, a first gap b is formed between the cutter and the inner side wall of the first barrel body 11, a second gap c is formed between the cutter and the blocking rib 111 in the axial direction of the first barrel body 11, and a third gap d is formed between the cutter and the feed inlet, wherein the value of the first gap b is 2 mm≤b≤12 mm, the value of the second gap c is 3 mm≤c≤15 mm, and the value of the third gap d is 3 mm≤d≤20 mm.

(51) In one embodiment, a first gap b is formed between the inner side wall of the first barrel body 11 and the cutter, the food entering the first barrel body 11 is located in the first gap b and is cut into small pieces by the cutter, and the food that has been cut into small pieces is pushed to the communication port along the cutter under the guide of the cutter and enters the second barrel body 12 through the communication port. Moreover, by the setting of distance, it is possible to ensure, to the largest extent, the cutting effect of the food and the discharge effect that the cut food is discharged from the communication port into the second barrel body 12. In one embodiment, the material of the cutter can be metal such as stainless steel, etc., or plastic, ceramic, etc. Furthermore, the number of the cutter can be one, two or more, and the cutter can have a single-blade, double-blade or multi-blade structure, etc.

(52) In one embodiment, as shown in FIGS. 2-4, the size of the first barrel body 11 is gradually reduced from the end close to the feed inlet to the end close to the communication port.

(53) In one embodiment, the first barrel body 11 can be arranged to have a shape that the upper portion thereof is larger than the lower portion thereof. In one embodiment, if the first barrel body 11 is circular, the diameter of the first barrel body 11 is gradually reduced from top to bottom, and if the first barrel body 11 is non-circular, the width and the length of the cross section of the first barrel body 11 are gradually reduced from top to bottom. Such configuration enables the food to be cut into smaller and smaller pieces. In one embodiment, for example, when the food just enters the first barrel body 11, the particle size of the food is large, the distance between the inner side wall of the first barrel body 11 and the smashing device 13 is adapted to the particle size of the food, and under the effect of the smashing device 13 and the first barrel body 11, the food is gradually smashed into smaller particles and gradually moves to the communication port, thus, the gap close to the communication port is set to be relatively small, so that on the one hand, the gap can be adapted to the particle size of the food here, and on the other hand, the food here can be further smashed into smaller particles by the smashing device 13, which thereby can achieve sufficient smashing of the food step by step, and further improve the juice yield of the food.

(54) In one embodiment, when the smashing device 13 is a grinding spiral head and the squeezing device 14 is a squeezing screw rod, the rotational speed ratio between the first drive shaft 213 and the second drive shaft 215 is A, wherein the value of the rotational speed ratio A is 0.8≤A≤1.5, in one embodiment, for example, when the rotational speed of the grinding spiral head is 60 RPM, the rotational speed of the squeezing screw rod is set to 48 RPM-90 RPM. When the smashing device 13 is a cutter and the squeezing device is a squeezing screw rod, the rotational speed ratio A between the first drive shaft 213 and the second drive shaft 215 ranges from 1 to 3, in one embodiment, for example, when the rotational speed of the squeezing screw rod is set to 60 RPM, the rotational speed of the cutter is 60 RPM-180 RPM.

(55) In one embodiment, by reasonably setting the rotational speed ratio between the first drive shaft 213 and the second drive shaft 215, it is possible to adapt the food grinding degree to the squeezing and discharging degree, which thereby can prevent the occurrence of the cases such as insufficient food grinding or insufficient squeezing, so that the food not only can be sufficiently ground but also can be sufficiently squeezed, thereby improving the juice yield of the food.

(56) In one embodiment, as shown in FIGS. 2 and 3, the food processor further comprises: a feeding barrel 17 which is arranged on the first barrel body 11, and on which the feed inlet is arranged.

(57) In one embodiment, one feeding barrel 17 can be arranged for feeding control of the food, and in such a case, the feed inlet is arranged in the feeding barrel 17.

(58) In another technical solution, it is of course feasible to directly place the food into the first barrel body 11 at once without arranging a feeding barrel 17, as shown in FIG. 4, and in such a case, the first barrel body 11 is provided with a barrel cover that can be opened or closed, and the feed inlet is just the opening of the first barrel body 11.

(59) In one embodiment, as shown in FIGS. 2-4, the host assembly 2 further comprises a base 22 and a shell 23, wherein the shell 23 and the base 22 define an accommodation cavity, and the drive assembly 21 is installed on the base 22 and located in the accommodation cavity. In one embodiment, the host assembly 2 further comprises: a control module for controlling working parameters of the food processor, In one embodiment, e.g., the rotational speed of the smashing device 13 and the squeezing device 14, etc.

(60) In one embodiment, the host assembly 2 further comprises: a power supply module for supplying power to the parts of the food processor, such as the drive assembly 21, and comprising at least a power supply plug that can be connected to the mains supply, so that in specific use, the power supply plug can be directly connected to the mains supply so as to supply power to the food processor.

(61) In one embodiment, the food processor includes a juice machine and a juicer.
