Description

Technical Field

[0001] This application relates to the field of small household appliance technology, and more specifically, to a food processor. Background Technology

[0002] Some food processors have both automatic grinding and automatic filtering functions. The required speed is different for the two working modes. For example, a high speed is needed when grinding to achieve better grinding results, while a low speed is needed when filtering to avoid the filter cartridge vibrating eccentrically and making a lot of noise due to high speed rotation. Summary of the Invention

[0003] This application provides a food processor that can meet the different speed requirements of pulverizing and filtering modes.

[0004] A food processor, comprising:

[0005] The host includes a first output terminal and a second output terminal, wherein the rotational speed of the first output terminal is different from that of the second output terminal;

[0006] The cup assembly includes a cup body and a stirring part and a filtering part installed on the cup body. The cup assembly can be detachably installed on the main unit in a first installation method and a second installation method. The first installation method is in which the stirring part is engaged with the main unit, and the second installation method is in which the filtering part is engaged with the main unit. In the first installation method, the first output terminal is drivenly connected to the stirring part, and in the second installation method, the second output terminal is drivenly connected to the filtering part.

[0007] The food processor provided in this application has a first output end and a second output end on the main unit that can output different speeds. In a first installation mode, the first output end can transmit power to the mixing section, and in a second installation mode, the second output end can transmit power to the filtering section, thereby meeting the different speed requirements of the grinding and filtering modes. Furthermore, the first and second output ends are located on the main unit 10, which simplifies the structure of the mixing and filtering sections.

[0008] Optionally, the main unit includes a motor and a gearbox connected to the motor. The motor includes a motor shaft, and the gearbox includes a power input terminal connected to the motor shaft and a power output terminal for power output. One of the motor shaft and the power output terminal is designated as the first output terminal, and the other as the second output terminal. In this design, the motor shaft directly serves as either the first or second output terminal, which simplifies the structure of the gearbox by requiring only one output terminal.

[0009] Optionally, the first output end is provided with a first lower clutch, the stirring section is provided with a first upper clutch that engages with the first lower clutch, the second output end is provided with a second lower clutch, and the filtering section is provided with a second upper clutch that engages with the second lower clutch. The second lower clutch is provided with a recess, and the first lower clutch is disposed within the recess and coaxial with the second lower clutch. This arrangement allows the first lower clutch to be housed within the second lower clutch, saving space and making the main unit's structure more compact.

[0010] Optionally, the main unit further includes a first circuit and a first switch that controls the on / off state of the first circuit. The motor is connected to the first circuit, and the stirring unit includes a first trigger unit that can trigger the first switch unit to close in the first installation method. In the first installation method, the motor can only be powered on after the first switch unit is closed, which improves the safety of the stirring unit installed on the main unit.

[0011] Optionally, the main unit further includes a second circuit and a second switch that controls the on / off state of the second circuit. The motor is connected to the second circuit, and the filter unit includes a second trigger unit that can trigger the second switch unit to close in the second installation method. In the second installation method, the motor can only be energized after the second switch unit is closed, which improves the safety of the filter unit installed in the main unit.

[0012] Optionally, the host includes a first switch section and / or a second switch section, wherein one of the first switch section and the second switch section is a push-type switch section. The push-type switch section includes a movable push rod and a switch. The push rod is movable under the action of a triggering force and drives the switch to close. This triggering method is mechanical, with a simple and reliable structure.

[0013] Optionally, the push-type switch further includes an elastic element that can extend and retract along the direction of movement of the push rod. One end of the elastic element along the extension direction is fixed, and the other end along the extension direction acts on the push rod. The elastic element is used to drive the push rod to reset after the force is removed. The elastic element enables automatic reset of the push rod, eliminating the need for manual operation and making circuit switching more convenient and safer.

[0014] Optionally, the stirring unit further includes a stirring base, a stirring element rotatably mounted on the stirring base, and a first trigger unit. The first trigger unit is movably disposed on the stirring base. When the stirring unit and the cup are in the installed state, the first trigger unit extends out of the stirring base under the pressure of the cup and remains fixed. When the stirring unit and the cup are in the disassembled state, the first trigger unit can retract into the stirring base. With this configuration, when the stirring unit is mistakenly installed separately on the main unit, the first trigger unit is in a free state, and the first trigger unit cannot trigger the first circuit to be connected, so the motor shaft will not rotate, making it safer to use.

[0015] Optionally, the filter unit further includes a filter cartridge holder and a filter cartridge rotatably mounted on the filter cartridge holder. The second trigger is movably disposed on the filter cartridge holder. When the filter unit and the cup body are in the installed state, the second trigger extends out of the filter cartridge holder under the pressure of the cup body and remains fixed. When the filter unit and the cup body are in the disassembled state, the second trigger can retract into the filter cartridge holder. With this configuration, when the filter unit is mistakenly installed separately on the main unit, the second trigger is in a free state, and the second trigger cannot trigger the second circuit to be connected, so the motor shaft will not rotate, making it safer to use.

[0016] Optionally, at least one of the stirring section and the filtering section includes a screw-on base, which is connected to the cup body by screwing. The screw-on base also has a locking part with a locking position and an unlocking position. In the locking position, the screw-on base and the cup body remain relatively fixed in the screwing direction. In the unlocking position, the screw-on base is detachable. The installation method is simple and reliable.

[0017] Optionally, in the first installation method, the stirring part is screwed and fixed to the main unit; and / or

[0018] In the second installation method, the filter unit is screwed and fixed to the main unit. This screwing method is convenient for installation. Attached Figure Description

Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0028] Please refer to Figure 1 and Figure 2 , Figure 1 This is a cross-sectional view of a food processor 100 shown as an exemplary embodiment of this application, wherein the cup assembly 20 is in a first mounting configuration. Figure 2 for Figure 1 Another cross-sectional view of the food processor 100 shown in the figure, in which the cup assembly 20 is in a second mounting configuration.

[0029] This application provides a food processor 100, including a main unit 10 and a cup assembly 20, the cup assembly 20 being detachably mounted to the main unit 10. The cup assembly 20 includes a cup body 21, a stirring part 22, and a filtering part 23, both of which are detachably mounted to the cup body 21.

[0030] exist Figure 1 In the embodiment shown, the stirring part 22 is engaged with the motor shaft of the main unit 10, so that the stirring part 22 is connected to the motor shaft for transmission, which can automatically stir the food in the cup body 21. This installation method is the first installation method for the cup assembly 20 to be installed on the main unit 10.

[0031] exist Figure 2 In the illustrated embodiment, the filter unit 23 is engaged with the motor shaft of the main unit 10, thereby establishing a drive connection between the filter unit 23 and the motor shaft of the main unit 10, and automatically filtering the crushed food inside the cup body 21. This installation method is a second installation method for mounting the cup assembly 20 onto the main unit 10.

[0032] The main unit 10 also includes a first output terminal 101 and a second output terminal 102, wherein the rotational speed of the first output terminal 101 is different from that of the second output terminal 102. In the first installation method, the first output terminal 101 is drivenly connected to the stirring unit 22, and in the second installation method, the second output terminal 102 is drivenly connected to the filtering unit 23.

[0033] As described above, the first output terminal 101 and the second output terminal 102 of the main unit 10 can output different speeds respectively. In the first installation mode, the first output terminal 101 can transmit power to the stirring section 22, and in the second installation mode, the second output terminal 102 can transmit power to the filtering section 23, so as to meet the different speed requirements of the pulverizing mode and the filtering mode. In addition, the fact that the first output terminal 101 and the second output terminal 102 are located on the main unit 10 can make the structure of the stirring section 22 and the filtering section 23 simpler.

[0034] Please combine Figure 3 , Figure 3 A cross-sectional view of the food processor 100 with some parts of its structure removed.

[0035] In one embodiment, the host 10 includes a motor 11 and a gearbox 12 drivenly connected to the motor 11. The motor 11 includes a motor shaft 110, and the gearbox 12 includes a power input terminal connected to the motor shaft 110 and a power output terminal for power output. One of the motor shaft 110 and the power output terminal is designated as the first output terminal 101, and the other is designated as the second output terminal 102. In this scheme, the motor shaft 110 directly serves as either the first output terminal 101 or the second output terminal 102, which allows the gearbox 12 to have only one output terminal, thus simplifying its structure.

[0036] It should be noted that the speed at the power output end of the gearbox 12 can be higher or lower than the speed of the motor shaft 110. The gearbox 12 includes, but is not limited to, a gear set.

[0037] In one embodiment, such as Figure 1 and Figure 2As shown, the first output end 101 is provided with a first lower clutch 103, the stirring part 22 is provided with a first upper clutch 24 that engages with the first lower clutch 103, the second output end 102 is provided with a second lower clutch 104, and the filtering part 23 is provided with a second upper clutch 25 that engages with the second lower clutch 104. The second lower clutch 104 is provided with a recess, and the first lower clutch 103 is disposed in the recess and coaxial with the second lower clutch 104. With this arrangement, the first lower clutch 103 is housed within the second lower clutch 104, saving space and making the structure of the main unit 10 more compact.

[0038] In one embodiment, such as Figure 1 As shown, the main unit 10 also includes a first circuit and a first switch 13 for controlling the on / off state of the first circuit. The motor 11 is connected to the first circuit. The stirring unit 22 includes a first trigger 221, which can trigger the first switch 13 to close in the first installation mode. That is, in the first installation mode, the motor 11 can only be powered on after the first switch 13 is closed, which improves the safety of the stirring unit 22 installed on the main unit 10.

[0039] In one embodiment, such as Figure 1 As shown, the host 10 also includes a second circuit and a second switch 14 for controlling the on / off state of the second circuit. The motor 11 is connected to the second circuit. The filter unit 23 includes a second trigger 231, which can trigger the second switch 14 to close in the second installation mode. That is, in the second installation mode, the motor 11 can only be powered on after the second switch 14 is closed, which improves the safety of the filter unit 23 installed in the host 10.

[0040] In this embodiment, the first switch part 13 and the second switch part 14 are the same switch part, which can reduce the number of switch parts in the host 10 and simplify the structure of the host 10.

[0041] It should be noted that the motor 11 includes a first terminal and a second terminal. The motor 11 can be connected to the first circuit through the first terminal and to the second circuit through the second terminal.

[0042] Please refer to Figure 4 , Figure 4 for Figure 1 A magnified view of part A in the middle.

[0043] In one embodiment, the host 10 includes a first switch portion 13, which is a push-type switch portion. The push-type switch portion includes a movable push rod 141 and a switch 142. The push rod 141 is movable under a triggering force, driving the switch 142 to close. This triggering method is mechanical, simple in structure, and reliable. The switch 142 includes, but is not limited to, a microswitch. Figure 1 and Figure 4 In the embodiment shown, the push rod 141 can move downward under the force of the first trigger part 221, but it is not limited to this; for example, it can also move laterally to the left or right.

[0044] exist Figure 4 In the illustrated embodiment, the push-type switch further includes an elastic element 143. The elastic element 143 is extendable and deformable along the direction of movement of the push rod 141. One end of the elastic element 143 along the extension / detension direction is fixed, and the other end acts on the push rod 141. The elastic element 143 drives the push rod 141 after the force of the first trigger part 221 is removed, achieving automatic reset of the push rod 141 without manual operation, making circuit switching more convenient and safer. The elastic element 143 includes, but is not limited to, a compression spring. Figure 4 In the embodiment shown, the elastic element 143 is sleeved on a column to prevent the elastic element 143 from shifting.

[0045] It should be noted that the second switch unit 14 can adopt the same structure as the first switch unit 13, which will not be described in detail here. Of course, the second switch unit 14 can also adopt other embodiments.

[0046] Please refer to Figure 5 , Figure 5 This is an exploded view of the cup component 20.

[0047] The stirring unit 22 also includes a stirring base 222 and a stirring element 223 rotatably mounted on the stirring base 222. The stirring element 223 is disposed within the cup cavity 210 of the cup body 21 and is used to stir food. In one embodiment, the first trigger 221 is movably disposed on the stirring base 222. When the stirring unit 22 and the cup body 21 are in the installed state, the first trigger 221 extends out of the stirring base 222 under the abutment of the cup body 21 and remains fixed. When the stirring unit 22 and the cup body 21 are in the disassembled state, the first trigger 221 can retract into the stirring base 222. With this configuration, when the stirring unit 22 is mistakenly installed alone on the main unit 10, the first trigger 221 is in a free state, and the first trigger 221 cannot trigger the first circuit to be connected, so the motor shaft 110 will not rotate, making it safer to use.

[0048] exist Figure 5In the embodiment shown, the filter section 23 further includes a filter cylinder seat 232 and a filter cylinder 233 rotatably mounted on the filter cylinder seat 232. The filter cylinder 233 communicates with the cup cavity 210 of the cup body 21 and is used to filter food.

[0049] The second trigger part 231 is movably disposed in the filter cartridge seat 232. When the filter part 23 and the cup body 21 are in the installed state, the second trigger part 231 extends out of the filter cartridge seat 232 under the abutment of the cup body 21 and remains fixed. When the filter part 23 and the cup body 21 are in the disassembled state, the second trigger part 231 can retract into the filter cartridge seat 232. With this configuration, when the filter part 23 is mistakenly installed alone on the main unit 10, the second trigger part 231 is in a free state, and the second trigger part 231 cannot trigger the second circuit to be connected, so the motor shaft 110 will not rotate, making it safer to use.

[0050] In one embodiment, at least one of the stirring base 222 and the filter cartridge seat 232 is configured as a screw-on base, that is, the stirring base 222 and / or the filter cartridge seat 232 are screwed onto the cup body 21, which is simple and reliable.

[0051] Please refer to Figure 6 and Figure 7 , Figure 6 This is a schematic diagram showing the locking part 224 in the locked position. Figure 7 This is a schematic diagram of the locking part 224 shown in an exemplary embodiment of this application.

[0052] In one embodiment, the screw-on base further includes a locking part 224, which has a locking position and an unlocking position. In the locking position, the screw-on base and the cup body 21 remain relatively fixed in the screwing direction. This prevents the screw-on base from rotating back in the opposite direction when screwed into the cup body 21, ensuring the reliability of the screw-on base installation. In the unlocking position, the screw-on base is detachable, thus ensuring that the screw-on base can be easily removed.

[0053] Taking the locking part 224 of the pulverizer holder 222 as an example, the locking part 224 includes a movable member 2241 and a locking rod 2242 movably disposed in the pulverizer holder 222. The locking rod 2242 moves under the force of the movable member 2241. In the locked position, the locking rod 2242 extends out of the pulverizer holder 222 and engages with the cup body 21, that is, it is inserted into the first locking hole 217. In the unlocked position, the locking rod 2242 retracts into the pulverizer holder 222 and separates from the cup body 21, that is, it exits from the first locking hole 217. In this configuration, the movable member 2241 is the driving member and the locking rod 2242 is the driven member. When an external force F is applied to the movable member 2241, the external force F is transmitted to the locking rod 2242 via the movable member 2241. In other words, power transmission is achieved through the cooperation of the movable part 2241 and the locking rod 2242, enabling the locking rod 2242 to move in the expected direction, and the setting position of the locking part 224 is also more flexible. The locking part 224 of the filter cartridge seat 232 has the same structure as the locking part 224 of the pulverizer seat 222, and will not be described again here.

[0054] The movement of the movable part 2241 and the locking rod 2242 is not limited. For example, the movable part 2241 and the locking rod 2242 can be connected by a lead screw and nut. The movable part 2241 rotates and the locking rod 2242 moves on the movable part 2241.

[0055] In this embodiment, the movable component 2241 and the locking rod 2242 are movable, and the moving direction of the movable component 2241 is perpendicular to the moving direction of the locking rod 2242. In this way, the direction of power transmission can be changed by a simple combination of motion forms, making the structure simpler and more compact.

[0056] like Figure 7 As shown, the movable component 2241 is provided with a button 22410 and an inclined driving slope 22411. Figure 7 Pressing button 22410 in the direction indicated by the middle arrow moves movable component 2241 in that direction. The driving ramp 22411 of movable component 2241 abuts against locking rod 2242, applying force to the locking rod 2242 via the driving ramp 22411. At this time, locking rod 2242 moves along the driving ramp 22411 and is lifted upwards, thus achieving movement of locking rod 2242 in a direction perpendicular to the movement direction of movable component 2241. After locking rod 2242 moves along the driving ramp 22411 and is lifted upwards, locking rod 2242 is in the unlocked position.

[0057] Of course, a driven inclined surface 22420 can also be provided on the locking rod 2242, and the driven inclined surface 22420 abuts against the movable part 2241, which can also realize the upward movement of the locking rod 2242.

[0058] exist Figure 7 In the embodiment shown, the movable member 2241 is provided with a driving inclined surface 22411, and the locking rod 2242 is provided with a driven inclined surface 22420. This makes the locking rod 2242 driven by the movable member 2241, resulting in smoother movement and less driving resistance.

[0059] In one embodiment, the locking part 224 further includes a second elastic element 2243, which includes, but is not limited to, a compression spring. The second elastic element 2243 is extendable and retractable along the moving direction of the locking rod 2242. One end of the second elastic element 2243 in the extension / retraction direction is fixed relative to the crushing blade holder 222, and the other end in the extension / retraction direction is connected to the locking rod 2242. The second elastic element 2243 can reset the locking rod 2242 after the external force F is removed, placing the locking rod 2242 in the locked position. The second elastic element 2243 is an energy storage element; after the external force F is removed, the second elastic element 2243 releases energy, causing the locking rod 2242 to automatically reset, making the unlocking operation more convenient and reliable.

[0060] To prevent the locking rod 2242 from shifting or tilting during movement, the crushing blade holder 222 is also provided with a limiting hole 2220, in which the locking rod 2242 remains at all times during movement. This design allows the inner wall of the limiting hole 2220 to restrict significant shifting of the locking rod 2242 during extension or retraction, providing a guiding function during movement and preventing the second elastic element 2243 from tipping over.

[0061] In one embodiment, under the first installation method, the stirring part 22 is screwed and fixed to the main unit 10, which is convenient for installation. The stirring part 22 is provided with a snap-fit; when the stirring part 22 is screwed into position relative to the main unit 10, the snap-fit ​​is engaged and fixed to the main unit 10. Under the second installation method, the filter part 23 is screwed and fixed to the main unit 10, which is also convenient for installation. The filter part 23 is provided with a snap-fit; when the filter part 23 is screwed into position relative to the main unit 10, the snap-fit ​​is engaged and fixed to the main unit 10.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
