Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, in particular to a food processor. Background Art

[0002] With the improvement of people's living standards, various household appliances have emerged. For example, cooking equipment meets people's dietary needs, and washing machines, hair dryers, massagers, etc. meet personal care needs. Different devices have different speed and torque requirements in different modes. In existing electrical equipment, especially food processing machines, when direct motor output is adopted, electronic speed regulation is often adopted, resulting in extremely low output torque of the motor at low speed, which cannot drag heavy load operation. The scheme of configuring a gear speed change component at the output end of the motor can achieve speed increase / reduction, but because its transmission ratio is a fixed value, it cannot achieve the effect of taking high and low speed into account. The fixed transmission ratio can only realize a single scene, which cannot meet people's diverse usage needs; therefore, when different speeds are required for different cooking methods, the entire machine usually needs to be replaced, which has a high replacement cost and requires a larger space in the home to store different cooking equipment.

[0040] The present invention provides a food processor.

[0041] In an embodiment of the present invention, please refer to Figures 1 to 6 , the food processor includes a housing 1 and a processing cup assembly 2; a driving motor 10 and a clutch speed change mechanism are arranged in the housing 1. The clutch speed change mechanism includes a driving shaft 13, an output shaft 40 and a speed change assembly 20. When the driving motor 10 drives the driving shaft 13 to rotate in different directions, the speed change assembly 20 has different coupling states to drive the output shaft 40 to operate at different speeds; the processing cup assembly 2 includes a cup body 2a and at least two different stirring assemblies mounted on the cup body 2a. The cup body 2a is mounted on the housing 1. The stirring assemblies are in transmission coupling with the output shaft 40 and are detachably connected. Different stirring assemblies are selectively mounted on the output shaft 40 to adapt to different speeds of the output shaft 40.

[0042] By arranging the driving motor 10 and the clutch speed change mechanism in the housing 1, the housing 1 has a good protection effect on the driving motor 10 and the clutch speed change mechanism. Specifically, an installation cavity is formed in the housing 1, and the driving motor 10 and the clutch speed change mechanism are arranged in the installation cavity. The housing 1 can be set as a detachable first housing and a second housing, and the first housing and the second housing jointly enclose to form the installation cavity. By detachably connecting the first housing and the second housing, it is convenient for users or workers to disassemble, assemble and repair the driving motor 10 and the clutch speed change mechanism. Of course, in another embodiment, the first housing of the housing 1 and the second housing of the housing 1 can also be connected in a non-detachable manner by welding or bonding, etc. On the one hand, it can ensure the stability of the connection between the first housing and the second housing, and on the other hand, it can also make the first housing and the second housing have a good sealing effect, prevent water or dust from entering the interior of the housing 1, and at the same time play a certain role in isolating the noise generated by the driving motor 10 and the clutch speed change mechanism inside the housing 1, reducing the noise generated during the use of the food processor.

[0043] The driving shaft 13 of the clutch speed change mechanism is connected to the driving motor 10, and the driving motor 10 can drive the driving shaft 13 to rotate. Specifically, the driving motor 10 includes a motor body 11 and a driving shaft 12, and the driving shaft 12 can be directly connected to the driving shaft 13, or the driving shaft 12 of the driving motor 10 can be connected to the driving shaft 13 through a gear assembly transmission. In another embodiment, the driving shaft 13 can also be used as the driving shaft 12 of the driving motor 10, that is, the driving shaft 13 and the driving shaft 12 of the driving motor 10 are integrated into one component, thereby reducing the noise during the transmission process. In addition, the driving motor 10 also has a motor housing, and the motor body 11 and the driving shaft 12 are both arranged in the motor housing, and the clutch speed change mechanism can also be arranged in the motor housing, thereby further reducing the noise of the food processor. The driving shaft 13 in the technical solution of the present invention has different rotation directions when driven by the driving motor 10. When the driving shaft 13 rotates in different directions, the speed change assembly 20 has different coupling states to drive the output shaft 40 to run at different speeds, so that the food processor in the technical solution of the present invention can output different transmission ratios, thereby providing different output modes to meet people's demand for the diversified functions of the food processor. The processing cup assembly 2 in the technical solution of the present invention includes a cup body 2a and at least two different stirring assemblies installed on the cup body 2a. The cup body 2a is installed on the housing 1. The stirring assembly is coupled with the output shaft 40 in a transmission manner and is detachably connected. When the output shaft 40 outputs different speeds, different stirring assemblies can be installed on the output shaft 40 accordingly, so as to adapt to different food processing scenarios. For example, when the driving motor 10 drives the driving shaft 13 to rotate forward, the speed change assembly 20 has a first coupling state to drive the output shaft 40 to operate at a high speed and a small torque state, which is suitable for whipping juice or grinding food materials; when the driving motor 10 drives the driving shaft 13 to rotate reversely, the speed change assembly 20 has a second coupling state to drive the output shaft 40 to operate at a low speed and a large torque state, which is suitable for kneading noodles or cooking food materials. In addition, since the stirring assembly is detachably connected to the output shaft 40, the user only needs to replace different stirring assemblies under different coupling states of the speed change assembly 20, without having to replace the cup body 2a installed on the housing 1 and the stirring assembly connected to the output shaft 40 as a whole, thereby saving replacement costs and reducing the volume of the replaced parts, reducing the space occupied by the entire food processor and the number of parts that need to be replaced. In the process of speed transmission of the clutch transmission mechanism, the speed change assembly 20 in the clutch transmission mechanism can be a two-stage transmission assembly, a three-stage transmission assembly, a four-stage transmission assembly or a multi-stage transmission assembly. Considering the stability of the transmission and the space occupied by the speed change assembly 20, the speed change assembly 20 can usually be set as a two-stage transmission assembly or a three-stage transmission assembly. In addition, the stirring assembly includes a stirring shaft 2b and a stirring blade 2c, the stirring shaft 2b is transmission-coupled with the output shaft 40, and the stirring blade 2c is installed in the cup body 2a and connected to the end of the stirring shaft 2b away from the output shaft 40.Among them, the stirring shaft 2b is detachably connected to the output shaft 40; and / or, the stirring blade 2c is detachably connected to the stirring shaft 2b. It can be understood that when the output shaft 40 operates at different speeds, the stirring shaft 2b and the stirring blade 2c can be selectively replaced together, and the replaced stirring shaft 2b and stirring blade 2c are installed on the output shaft 40; when the stirring shaft 2b is not detachably connected to the output shaft 40, but the stirring blade 2c is detachably connected to the stirring shaft 2b, when the output shaft 40 operates at different speeds, different stirring blades 2c can be selectively installed on the stirring shaft 2b. In order to save the replacement cost, in the present invention, the optional stirring assembly includes a stirring shaft 2b and at least two different stirring members 2c. The stirring shaft 2b is in transmission coupling with the output shaft 40, and the stirring members 2c are detachably installed on the stirring shaft 2b. Different stirring members 2c are selectively installed on the stirring shaft 2b to adapt to different speeds of the output shaft 40.

[0044] In the technical solution of the present invention, by arranging a driving motor 10 and a clutch speed change mechanism in the housing 1, the housing 1 has a good protective effect on the driving motor 10 and the clutch speed change mechanism. When the driving motor 10 drives the main shaft 13 of the clutch speed change mechanism to rotate in different directions, the speed change assembly 20 of the clutch speed change mechanism has different coupling states and drives the output shaft 40 of the clutch speed change mechanism to operate at different speeds, so that the food processor in the present invention can output different transmission ratios, and further the food processor outputs different modes to adapt to different use scenarios, thereby meeting the diverse use requirements of people for the functions of the food processor. In addition, the processing cup body 2a assembly includes a cup body 2a, a stirring shaft 2b installed on the cup body 2a, and at least two different stirring members 2c; the cup body 2a is installed on the housing 1, the stirring shaft 2b is in transmission coupling with the output shaft 40, and the stirring member 2c is detachably connected to the stirring shaft 2b. Then when the output shaft 40 has the above different output speeds, the stirring shaft 2b also has different speeds. Furthermore, at different speeds, the stirring shaft 2b can selectively connect with different stirring members 2c to adapt to different food processing scenarios, meeting the diverse function requirements of people for the food processor.

[0045] Specifically, please refer to Figures 1 to 4 , the stirring member 2c includes a stirring blade and a dough mixing blade. The output shaft 40 has a first speed operation mode and a second speed operation mode. Among them, the speed of the first speed operation mode is greater than the speed of the second speed operation mode. When in the first speed operation mode, the stirring blade is installed on the stirring shaft 2b. When in the second speed operation mode, the dough mixing blade is installed on the stirring shaft 2b.

[0046] If the first rotational speed is greater than the second rotational speed, the first rotational speed is defined as the high speed and the second rotational speed is defined as the low speed. In the high-speed state, stirring blades are installed on the stirring shaft 2b, so as to achieve the effect that the output shaft 40 drives the stirring blades to rotate at a high speed through the stirring shaft 2b, thereby meeting the whipping requirements of fruit juice or other food ingredients. In the low-speed state, dough mixing blades are installed on the stirring shaft 2b, so as to achieve the effect that the output shaft 40 drives the dough mixing blades to rotate at a low speed with a large torque through the stirring shaft 2b, thereby meeting the user's dough kneading requirements. It is realized that one housing 1 can cooperate with multiple stirring members 2c to meet the diverse usage requirements of users for food processors.

[0047] In another embodiment of the present invention, please refer to Figures 1 to 4 together. The food processor includes a housing 1 and at least two different processing cup assemblies 2; a drive motor 10 and a clutch speed change mechanism are arranged in the housing 1. The clutch speed change mechanism includes a driving shaft 13, an output shaft 40 and a speed change assembly 20. When the drive motor 10 drives the driving shaft 13 to rotate in different directions, the speed change assembly 20 has different coupling states to drive the output shaft 40 to operate at different rotational speeds; the processing cup assemblies 2 are detachably installed on the housing 1 and are in transmission coupling with the output shaft 40, and different processing cup assemblies 2 are selectively installed on the output shaft 40 to adapt to different rotational speeds of the output shaft 40.

[0048] By arranging the drive motor 10 and the clutch speed change mechanism in the housing 1, the housing 1 has a good protective effect on the drive motor 10 and the clutch speed change mechanism. Specifically, an installation cavity is formed in the housing 1, and the drive motor 10 and the clutch speed change mechanism are arranged in the installation cavity. The housing 1 can be set as a detachable first housing and a second housing, and the first housing and the second housing jointly enclose to form the installation cavity. By detachably connecting the first housing and the second housing, it is convenient for users or workers to disassemble, assemble and repair the drive motor 10 and the clutch speed change mechanism, etc. Of course, in another embodiment, the first housing of the housing 1 and the second housing of the housing 1 can also be connected in a non-detachable manner by welding or bonding, etc. On the one hand, the connection stability between the first housing and the second housing can be ensured, and on the other hand, a good sealing effect can be achieved between the first housing and the second housing, avoiding water or dust from entering the interior of the housing 1, and at the same time, it also has a certain sound insulation effect on the noise generated by the drive motor 10 and the clutch speed change mechanism inside the housing 1, reducing the noise generated during the use of the food processor.

[0049] The driving shaft 13 of the clutch speed change mechanism is connected to the driving motor 10, so that the driving motor 10 can drive the driving shaft 13 to rotate. Specifically, the driving motor 10 can be directly connected to the driving shaft 13, or the driving motor 10 can be drivingly connected to the driving shaft 13 through a gear assembly; alternatively, the driving shaft 13 can also serve as the driving shaft 12 of the driving motor 10. The driving shaft 13 has different rotation directions under the drive of the motor. In the present invention, when the driving shaft 13 rotates in different directions, the speed change assembly 20 has different coupling states to drive the output shaft 40 to operate at different speeds, so that the food processor in the technical solution of the present invention can output different transmission ratios, and further provide different output modes to meet the diverse usage requirements of people for the functions of the food processor. The processing cup assembly 2 in the technical solution of the present invention is detachably mounted on the machine housing 1 and is drivingly coupled to the output shaft 40. When the output shaft 40 outputs different speeds, different processing cup assemblies 2 can be correspondingly mounted on the machine housing 1, so as to adapt to different food processing scenarios. For example, when the driving motor 10 drives the driving shaft 13 to rotate forward, the speed change assembly 20 has a first coupling state to drive the output shaft 40 to operate in a high-speed and low-torque state, which is applicable to the situation of juicing or grinding ingredients; when the driving motor 10 drives the driving shaft 13 to rotate reversely, the speed change assembly 20 has a second coupling state to drive the output shaft 40 to operate in a low-speed and high-torque state, which is applicable to the situation of kneading dough or cooking ingredients at this time. In addition, by detachably connecting the processing cup assembly 2 to the machine housing 1, the user only needs to replace different processing cup assemblies 2 under different coupling states of the speed change assembly 20. By replacing the entire processing cup assembly 2, the replacement process becomes more convenient, avoiding replacing small parts in the processing cup assembly 2 to increase the replacement difficulty. And, by having at least two different processing cup assemblies 2 corresponding to one machine housing 1, the number of machine housings 1 can be reduced on the premise of meeting different food processing scenarios, thereby reducing the space occupied by the food processor in the home and the number of parts to be replaced.

[0050] In the technical solution of the present invention, by arranging a drive motor 10 and a clutch speed change mechanism in the housing 1, the housing 1 has a good protection effect on the drive motor 10 and the clutch speed change mechanism. When the drive motor 10 drives the driving shaft 13 of the clutch speed change mechanism to rotate in different directions, the speed change assembly 20 of the clutch speed change mechanism has different coupling states and drives the output shaft 40 of the clutch speed change mechanism to operate at different speeds, so that the food processor in the present invention can output different transmission ratios, and further the food processor outputs different modes to adapt to different use scenarios, thereby meeting the diverse use requirements of people for the functions of the food processor. In addition, by providing at least two different processing cup assemblies 2a; the processing cup assembly 2 is detachably connected to the housing 1 and is in transmission connection with the output shaft 40, so when the output shaft 40 has the above different output speeds, different processing cup assemblies 2 can be selected to be connected thereto, thereby adapting to different food processing scenarios and meeting the diverse requirements of people for the functions of the food processor.

[0051] Further, please refer to Figure 1 and Figure 3 , the processing cup assembly 2 includes a wall-breaking cup assembly, a grinding cup assembly, a cooking cup assembly, and a dough-kneading cup assembly. The output shaft 40 has a first speed operation mode and a second speed operation mode. Among them, the speed of the first speed operation mode is greater than that of the second speed operation mode. In the first speed operation mode, the housing 1 is equipped with a wall-breaking cup assembly or the grinding cup assembly. In the second speed operation mode, the housing 1 is equipped with a cooking cup assembly or a dough-kneading cup assembly.

[0052] Since the first speed is greater than the second speed, the first speed is defined as the high speed and the second speed is defined as the low speed. In the high-speed state, a wall-breaking cup assembly or a grinding cup assembly is installed on the housing 1, so as to achieve the effect that the output shaft 40 drives the wall-breaking cup assembly or the grinding cup assembly to rotate at a high speed, thereby meeting the whipping requirements of fruit juice or other ingredients. In the low-speed state, a cooking cup assembly or a grinding cup assembly is installed on the housing 1, so as to achieve the effect that the output shaft 40 drives the cooking cup assembly or the dough-kneading cup assembly to rotate at a low speed with a large torque, thereby meeting the user's need for dough kneading. It realizes that one housing 1 can cooperate with multiple stirring members 2c to meet the diverse use requirements of users for the food processor.

[0053] In order to achieve the effect that when the driving shaft 13 rotates in different directions, the speed change assembly has different coupling states to drive the output shaft to operate at different speeds, in an embodiment, please refer to Figures 9 to 12 , the speed change assembly 20 further includes an input rotating body 30, an output rotating body 50, and a driven member 60. The input rotating body 30 is installed on the driving shaft 13 and can move on the driving shaft 13. The output rotating body 50 is installed on the output shaft 40 and can drive the output shaft 40 to rotate synchronously.

[0054] When the driving shaft 13 rotates in the first direction, the input rotating body 30 is in driving coupling with the output rotating body 50 so that the output shaft 40 operates at a first rotational speed. At this time, the output rotating body 50 is not in contact with the driven member 60. When the driving shaft 13 rotates in a direction opposite to the first direction, the input rotating body 30 moves along the driving shaft 13 to separate from the output rotating body 50, and the input rotating body 30 is in driving connection with the driven member. The output rotating body is also in driving coupling with the driven member, so that the input rotating body transmits power to the output rotating body 50 through the driven member 60, so that the output shaft 40 operates at a second rotational speed, wherein the first rotational speed is greater than the second rotational speed, and in the working state of the first rotational speed, the torque output by the output shaft 40 is greater than the torque output in the working state of the second rotational speed. Then, in the actual use process, one functional mode can be realized on the same food processor through the first rotational speed of the output shaft 40, and another functional mode can be realized at another rotational speed. Or the same food processor can be arranged by a driving motor to make the output shaft 40 operate in an alternating manner of the first rotational speed and the second rotational speed, so as to realize another functional mode.

[0055] In the present application, the movement of the input rotating body 30 along the driving shaft 13 can enable the input rotating body 30 to have two stopping positions. When the driving shaft 13 rotates in the first direction, the input rotating body 30 stops at the first position. The input rotating body 30 is located at the top of the driving shaft 13 and is in driving coupling with the output rotating body 50. At this time, no power is transmitted between the driven member 60 and the output rotating body 50, and the input rotating body 30 and the driven member 60 are also in a separated state. The driving shaft 13 directly drives the output rotating body 50 to rotate through the input rotating body 30 and drives the output shaft 40 to rotate synchronously with the driving shaft 13. At this time, the output shaft 40 outputs at a high rotational speed and a low torque. It can be understood that when the input rotating body 30 stops at the first position, the input rotating body 30 and the driven member 60 can also be in a contact coupling state. When the driving shaft 13 operates in a direction opposite to the first direction, the input rotating body 30 moves along the driving shaft 13 and stops at the second position. At this time, the input rotating body 30 moves to the lower part of the driving shaft 13. The input rotating body 30 is separated from the output rotating body 50, and the input rotating body 30 transmits power to the output rotating body 50 through the driven member 60, so that the output shaft 40 operates at a second rotational speed. At this time, the output shaft 40 is in a low rotational speed and high torque output state. When the output shaft 40 outputs at a relatively high rotational speed and a relatively low torque, it can be applied to, for example, crushing and whipping of food ingredients. In the second working state, when outputting at a relatively low rotational speed and a relatively large torque, it can be applied to, for example, the scenario of noodle making machine for kneading dough. And when switching and alternatingly operating between the first state and the second state, due to the different rotational speeds and torques, it is particularly applicable to, for example, the situation of stirring and mixing during the food ingredient processing process. In summary, the solution of the food processor proposed in the present application meets the usage requirements of people for the diversification of the functions of electrical appliances.

[0056] In order to realize the movement of the input rotating body 30 on the driving shaft 13, in one embodiment, the food processing machine further includes a driving member (not shown), which is used to drive the input rotating body 30 to move on the driving shaft 13, wherein the driving member has various structural forms. In one structural form, the driving member can be an electromagnet, which includes a first part installed on the input rotating body 30 and a second part installed on the housing 20a. Under the condition of different currents, the electromagnet generates forces in different directions to achieve the effects of repulsion and attraction on the input rotating body 30, driving the input rotating body 30 to move between the first position and the second position on the driving shaft 13. It can be understood that in the case of such a structural setting, the cross-sectional shape of the part of the driving shaft 13 where the input rotating body 30 is installed should be limited to the input rotating body 30 can only move along the axial direction of the driving shaft 13, and can not allow the input rotating body 30 to rotate in the circumferential direction relative to the driving shaft 13. For this reason, the cross-sectional shape of the part of the driving shaft 13 where the input rotating body 30 is installed can be set to, for example, a D-shaped, polygonal, or special-shaped structure. In another structural form, the driving member can also be a lever structure installed on the housing 20a. The lever structure has a driving end extending out of the housing 20a and an actuating end in contact with the input rotating body 30. The user can manually press the driving end so that the lever structure transmits power to the actuating end in a lever-like manner and thereby drives the input rotating body 30 to move along the driving shaft 13. Of course, the power source of the driving end can also be provided by other electrical components, such as being driven by other motors, or being driven by cylinders, etc. Similarly, when using a lever structure, the cross-sectional shape of the portion of the driving shaft 13 where the input rotating body 30 is installed should be such that the input rotating body 30 can only move axially along the driving shaft 13, and cannot rotate circumferentially relative to the driving shaft 13. For specific methods, please refer to the above content and will not be repeated here. That is, the concept of this embodiment is to drive the input rotating body 30 by applying external force through a driving member as a third party. In this way, the stroke is easier to control. It can be understood that the form of the driving member of the present application should not be limited to the two methods listed above, and a non-contact driving method or other feasible methods can also be used, for example, by blowing the input rotating body 30 along the driving shaft 13 through airflow to drive it to slide.

[0057] In order to realize the movement of the input rotary body 30 on the driving shaft 13, in another embodiment, please continue to refer to Figures 9 to 12, one of the driving shaft 13 and the input rotating body 30 is formed with a helical groove 14 extending in its axial direction, and the other of the two is formed with a guiding projection 34 adapted to be embedded in the helical groove 14. The input rotating body 30 is driven to move along the axial direction of the driving shaft 13 through the interaction between the guiding projection 34 and the helical groove 14. In one setting mode, the helical groove 14 is formed on the driving shaft 13, and the guiding projection 34 is formed on the inner wall of the input rotating body 30. The length of the helical groove 14 extending in the axial direction of the driving shaft 13 should be slightly greater than the distance from the first position to the second position. The guiding projection 34 is also helical and is provided in multiple segments. During operation, as Figure 10 shown, when the driving shaft 13 rotates in the first direction, the input rotating body 30 is driven by the driving force generated by the extrusion of the guiding projection 34 against the wall surface of the helical groove 14 to approach the output rotating body 50 and reach the first position, thereby realizing the transmission coupling between the input rotating body 30 and the output rotating body 50. As Figure 9 shown, when the driving shaft 13 rotates in the direction opposite to the first direction, the guiding projection 34 generates a reverse acting force on the input rotating body 30, so that the input rotating body 30 moves from the first position to the second position, and then contacts the driven member 60 at this position and can transmit power to the output rotating body 50. In this embodiment, the driving force of the input rotating body 30 is realized without relying on other external components, and is cleverly achieved by modifying the self-structures on the driving shaft 13 and the input rotating body 30. Therefore, the number of parts is reduced, the cost is lowered, and the overall structure of the food processor is made smaller and more compact.

[0058] In the embodiment where the input rotating body 30 is driven to move by the cooperation of the helical groove 14 and the guiding projection 34, in order to ensure the stability of the overall structure, in one embodiment, please refer to Figure 5 shown, a first limiting structure 22 is further provided on the driving shaft 13. The first limiting structure 22 is used to prevent the input rotating body 30 from spinning out of the helical groove 14. In one structural form, the first limiting structure 22 is a snap ring installed at one end of the driving shaft 13 facing the output shaft 40, and the driving shaft 13 can be provided with a clamping groove for clamping and fixing the snap ring. Further, in order to prevent the input rotating body 30 from colliding with the driving motor 10 when moving on the driving shaft 13 due to spinning out of the range of the helical groove 14, the first limiting structure 22 can further include another snap ring provided at the connection of the driving shaft 13 close to the driving motor 10, and this snap ring can also be clamped and fixed through the clamping groove formed on the driving shaft 13. It can be understood that the specific form of the first limiting structure 22 can also be other, such as a convex structure formed on the driving shaft 13.

[0059] In this embodiment, to ensure the stability during the driving process through the cooperation of the spiral groove 14 and the guiding protrusion 34, the groove width of the spiral groove 14 is defined as t, and the extension height of the guiding protrusion 34 in the axial direction of the input rotating body 30 is defined as h. Among them, h is not less than 1.5t. When the extension height of the guiding protrusion 34 in the axial direction of the input rotating body 30 is too small, the supporting force of the input rotating body 30 in the axial direction will be too small. In this way, phenomena such as slipping or insufficient structural strength are likely to occur. Therefore, setting h not less than 1.5t can ensure the stability during the operation process.

[0060] In one embodiment, please refer to Figure 5 As shown, the input rotating body 30 includes a first base portion 31. The shape of the first base portion 31 has various types. When the first base portion 31 is columnar, the first base portion 31 has a first end and a second end arranged oppositely. The first coupling portion 32 is provided at the first end of the first base portion 31 facing the output shaft 40, and the first transmission portion 33 is provided outside the second end of the first base portion 31. The first base portion 31 is formed with a shaft hole penetrating through the first end and the second end, and the shaft hole is used for the active shaft 13 to pass through and be installed. The above-mentioned guiding protrusion 34 is formed on the inner wall surface of the shaft hole. Among them, the first base portion 31, the first coupling portion 32, and the first transmission portion 33 can be an integral structure, or the three can be a split structure and assembled and fixed together, or two of the three can be an integral structure and assembled and fixed together with the other one.

[0061] Please refer to Figure 5 As shown, the output rotating body 50 includes a second base portion 51. The second coupling portion 52 is provided at one end of the second base portion 51 facing the active shaft 13, and the second transmission portion 53 is provided outside the second base portion 51. The output shaft 40 is passed through and installed in the second base portion 51. The second base portion 51, the second coupling portion 52, and the second transmission portion 53 in the output rotating body 50 can also be a split structure, or an integral structure, or a structure in which two of them are an integral structure and assembled with the other one. In addition, the structures of the input rotating body 30 and the output rotating body 50 of the present application can present a regular disk shape due to their own three-part structures, or they can also be irregular special-shaped structures.

[0062] The first coupling portion 32 and the second coupling portion 52 described in this application have various structural forms. In one setting mode, both the first coupling portion 32 and the second coupling portion 52 are one-way gear disc structures. In other setting modes, the first coupling portion 32 is a special-shaped groove structure formed by a depression on the end face of the first end, or the first coupling portion 32 is a threaded joint structure with an external thread formed on the outer wall surface of the first end, or the first coupling portion 32 is a plug joint structure with a plurality of protrusions protruding outward formed on the outer wall surface of the first end, and the second coupling portion 52 is a structure adapted to the first coupling portion 32.

[0063] Specifically, in order to achieve the above content in this application, the food processor outputs in various modes and working states with different transmission ratios. In one embodiment, please refer to Figures 7 to 12 , the input rotating body 30 has a first coupling portion 32 and a first transmission portion 33, and the output rotating body 50 has a second coupling portion 52 and a second transmission portion 53. When the driving shaft 13 rotates in the first direction, the first coupling portion 32 and the second coupling portion 52 are in transmission coupling. When the driving shaft 13 rotates in a direction opposite to the first direction, the first coupling portion 32 and the second coupling portion 52 are disengaged, and the first transmission portion 33 and the second transmission portion 53 are respectively in transmission coupling to different positions of the driven member 60, so that the output shaft 40 rotates in a second state. Wherein, the driven member 60 has a third transmission portion 61 and a fourth transmission portion 62. When the driving shaft 13 rotates in a direction opposite to the first direction, the first coupling portion 32 and the second coupling portion 52 are disengaged, and the first transmission portion 33 contacts and drives the third transmission portion 61, and the fourth transmission portion 62 contacts and drives the second transmission portion 53, so that the output shaft 40 rotates at a second rotational speed. Of course, the rotational speed and torque of the output shaft 40 rotating in the second working state in the solution of this application are also adjustable. Specifically, the size of the driven member 60 can be adjusted accordingly. In some embodiments, the first transmission portion 33, the second transmission portion 53, the third transmission portion 61, and the fourth transmission portion 62 are all ring gear structures, that is, the first transmission portion 33 and the third transmission portion 61, and the second transmission portion 53 and the fourth transmission portion 62 are all gear transmissions. Of course, the first transmission portion 33, the second transmission portion 53, the third transmission portion 61, and the fourth transmission portion 62 of this application can also be selected as friction cylindrical surface structures. Among them, the transmission method formed by gear meshing with a ring gear structure has the characteristics of stable structure and large load, and can be considered as a preferred solution. Of course, the friction driving method of the friction cylindrical surface structure makes the whole structure more simplified and easier to process and manufacture.

[0064] Furthermore, please refer to Figure 7 、 Figure 8 、 Figure 11 and Figure 12, in this embodiment, the output rotating body 50 is also arranged to be movable along the output shaft 40. Thus, when the driving shaft 13 rotates in the first direction, the input rotating body 30 moves along the driving shaft 13 towards the output rotating body 50 to the first position, and the first coupling portion 32 and the second coupling portion 52 are in driving coupling. And because the output rotating body 50 is also a movable solution, at this time, both the input rotating body 30 and the output rotating body 50 will be in a position not in contact with the driven member 60. When the driving shaft 13 rotates in the direction opposite to the first direction, the input rotating body 30 moves from the first position to the second position and separates from the output rotating body 50, and the output rotating body 50 also moves towards the input rotating body 30 direction and then contacts the driven member 60, so that the second transmission portion 53 and the fourth transmission portion 62 are in driving coupling. Specifically, as a way to implement this embodiment, the output shaft 40 is provided with a guiding portion, the output rotating body 50 is provided with a guiding hole, the guiding portion penetrates through the guiding hole, and the contour shapes of the guiding portion and the guiding hole are configured to define the axial movement of the output rotating body 50 along the output shaft 40; and the speed change assembly further includes a reset member 80, and the reset member 80 is used to drive the output rotating body 50 to move along the output shaft 40 towards the input rotating body 30 direction. That is, when the input rotating body 30 and the output rotating body 50 are in driving coupling through the first coupling portion 32 and the second coupling portion 52, the output rotating body 50 is driven by the input rotating body 30 to move a certain distance in the direction away from the driving shaft 13, so that it is not in contact with the driven member 60, and the reset member 80 is compressed. At the same time, in the separated state of the input rotating body 30, the reset member 80 provides a driving force, so that the output rotating body 50 moves towards the driving shaft 13 direction and then contacts the fourth transmission portion 62 of the driven member 60.

[0065] Specifically, the reset member 80 can be a spring or a spring piece that provides an elastic force. Among them, the spring or the spring piece is arranged between the housing and the second transmission member 50 and is in a compressed state. In other embodiments, the reset member 80 is a magnet that provides a magnetic force. In the solution where the reset member 80 is a magnet, a first magnet and a second magnet can be respectively arranged on the housing 20a and the output rotating body 50, and the first magnet and the second magnet are magnetically repulsive, so that the output rotating body 50 can always have a tendency to move along the output shaft 40 towards the driving shaft 13 direction.

[0066] Furthermore, in order to improve the structural stability, a second limiting structure 42 is further arranged on the output shaft 40, and the second limiting structure 42 is used to prevent the output rotating body 50 from detaching from the output shaft 40. The second limiting structure 42 of the present application is arranged at one end of the output shaft 40 facing the driving shaft 13. Among them, the specific form of the second limiting structure 42 can refer to the form of the above-mentioned first limiting structure 22, and will not be elaborated here.

[0067] In order to ensure that different parts of the food processor do not interfere with each other during operation on the basis of a compact overall structure, when the first coupling part 32 is in driving coupling with the second coupling part 52, an axial distance b is formed between the end of the first transmission part 33 facing away from the output shaft 40 and the end of the third transmission part 61 facing the output shaft 40, and an axial distance c is formed between the end of the second transmission part 53 facing the driving shaft 13 and the end of the fourth transmission part 62 facing away from the driving shaft 13. A distance d is formed between the end faces of the driving shaft 13 and the output shaft 40. Among them, both the distance b and the distance c are not less than 0.3 mm, and the distance d is not less than 0.2 mm. Since the input rotating body 30 and the output rotating body 50 are both in an axially movable state, through the above parameter design, sufficient clearance space is reserved to avoid the possibility of collision, and the stability of the structure is higher.

[0068] Please refer to Figure 7 and Figure 8 , in another embodiment of the speed change assembly 20, the input rotating body 30 in the speed change assembly 20 is divided into two parts, namely a first coupling part 32 and a first transmission part 33, and both the first coupling part 32 and the first transmission part 33 are fixedly arranged with the driving shaft 13. Among them, the first coupling part 32 and the first transmission part 33 are separately arranged, and the first coupling part 32 is fixed at the end of the driving shaft 13. The output rotating body 50 can also move along the output shaft 40. In one setting method, a reset part 80 (such as a spring) is also arranged on the output shaft 40. The output rotating body 50 and the output shaft 40 achieve axial sliding through shaft-hole cooperation and rotate together in the circumferential direction. The driven part 60 is still divided into two parts, namely a third transmission part 61 and a fourth transmission part 62, and in this embodiment, the driven part 60 can move along the pivot shaft 70. In one setting method, a spiral groove is also arranged on the pivot shaft 70, and the driven part 60 is threadedly connected with the spiral groove. The third transmission part 61 and the first transmission part 33 are in a constant coupling state. Thus, when the driving shaft 13 rotates in the Figure 7 direction shown by the arrow in, the third transmission part 61 rotates under the drive of the first transmission part 33, and due to the guiding action of the spiral groove on the pivot shaft 70, the driven part 60 rises in the direction shown in the figure. Since the outer diameter of the third transmission part 61 in this application is larger than the outer diameter of the fourth transmission part 62, the output rotating body 50 partially straddles the third transmission part 61 in the transverse direction. Therefore, during the rising process of the driven rotating body 60, it will abut against the output rotating body 50 to rise, so that the second coupling part 52 on the output rotating body 50 is separated from the first coupling part 32 of the input rotating body 30. Furthermore, the power is transmitted to the output rotating body 50 in the direction of the first transmission part 33, the third transmission part 61, and the fourth transmission part 62. At this time, it is in a low-speed and high-torque output state. And as Figure 8As shown, when the driving shaft 13 rotates in a direction opposite to the first direction, the output rotating body 50 is driven by the reset member 80 to press down, so that the second coupling portion 52 on the output rotating body 50 is in transmission coupling with the first coupling portion 32 on the input rotating body 30. At this time, since the first transmission portion 33 drives the driven rotating body 60 to rotate in the reverse direction, the driven rotating body 60 descends. As a result, the driven rotating body 60 is separated from the output rotating body 50. Therefore, the driving shaft 13 directly drives the output shaft 40 to rotate through the first coupling portion 32 and the second coupling portion 52. At this time, it is in a high-speed and low-torque output state.

[0069] In another embodiment of the speed change assembly 20, please refer to Figure 9 and Figure 10 . In the speed change assembly 20, the input rotating body 30 is divided into two parts: a first coupling portion 32 and a first transmission portion 33. However, the difference in this embodiment is that the first transmission portion 33 is fixedly arranged with the driving shaft 13, while the first coupling portion 32 can move along the driving shaft 13. In one setting form, there is a threaded fit between the first coupling portion 32 and the driving shaft 13. In this embodiment, the output rotating body 50 is fixed to the output shaft 40. The driven member 60 is still divided into two parts: a third transmission portion 61 and a fourth transmission portion 62. And in this embodiment, the driven member 60 can move along the pivot shaft 70. In one setting manner, a spiral groove is also provided on the pivot shaft 70, and the driven member 60 is threadedly connected to the spiral groove. The third transmission portion 61 and the first transmission portion 33 are in a constant coupling state. Thus, as Figure 9 shown, when the driving shaft 13 rotates in the first direction, the third transmission portion 61 rotates under the drive of the first transmission portion 33, and the driven member 60 rises due to the guiding action of the spiral groove on the pivot shaft 70. And the first coupling portion 32 moves downward along the driving shaft 13 due to the threaded guiding action and is separated from the second coupling portion 52. Then the power is transmitted to the output rotating body 50 in the direction of the first transmission portion 33, the third transmission portion 61, and the fourth transmission portion 62. At this time, it is in a low-speed and high-torque output state. As Figure 10 shown, when the driving shaft 13 rotates in the reverse direction of the first direction, since the first transmission portion 33 drives the driven rotating body 60 to rotate in the reverse direction, the driven rotating body 60 descends. As a result, the driven rotating body 60 is separated from the output rotating body 50. And the first coupling portion 32 moves upward along the driving shaft 13 due to the threaded guiding action and is coupled with the second coupling portion 52. Therefore, the driving shaft 13 directly drives the output shaft 40 to rotate through the first coupling portion 32 and the second coupling portion 52. At this time, it is in a high-speed and low-torque output state.

[0070] In another embodiment of the speed change assembly 20, please refer to Figure 11 and Figure 12, the input rotating body 30 is divided into a first input rotating body 30a and a second input rotating body 30b. The driven member 60 is still divided into a third transmission part 61 and a fourth transmission part 62. The third transmission part 61 and the fourth transmission part 62 are fixed on the pivot shaft 70. In this embodiment, the first input rotating body 30a is sleeved on the driving shaft 13 and is constantly coupled with the third transmission part 61, and the output rotating body 50 is constantly coupled with the fourth transmission part 62. The second input rotating body 30b can move along the driving shaft 13. In one setting mode, a spiral groove 14 is arranged on the driving shaft 13, and the second input rotating body 30b is in threaded fit with the spiral groove 14. In this embodiment, a first coupling part 32 is arranged at the upper end of the second input rotating body 30b, and a fourth coupling part 36 is arranged at the lower end. A third coupling part 35 is arranged at the upper end of the first input rotating body 30a, and the fourth coupling part 36 is matched with the third coupling part 35. In this embodiment, the output rotating body 50 can move along the output shaft 40 and a second coupling part 52 matched with the first coupling part 32 is arranged at the lower end. In one setting mode, the output rotating body 50 is in shaft hole fit with the output shaft 40, such as D-shaped structure fit, so that the output rotating body 50 can rotate circumferentially with the output shaft 40 and can slide up and down along the output shaft 40. A reset member 80 (which can be a spring) is also installed on the output shaft 40. The reset member 80 drives the output rotating body 50 to have a downward movement tendency. Thus, when the driving shaft 13 rotates in the first direction, driven by the spiral groove 14, the second input rotating body 30b rises, so that the second input rotating body 30b drives the output shaft 40 to rotate together with the driving shaft 13 through the transmission cooperation of the second coupling part 52 matched with the first coupling part 32. At this time, it is a high-speed and low-torque output state. When the driving shaft 13 rotates in the reverse direction of the arrow in Figure 12 , due to the action of the spiral groove 14, the second input rotating body 30b descends, the first coupling part 32 is separated from the second coupling part 52, and the first input rotating body 30a and the second input rotating body 30b are in transmission coupling through the fourth coupling part 36 and the third coupling part 35. Thus, the power drives the output shaft 40 to rotate through the transmission path of the first input rotating body 30a, the third transmission part 61, the fourth transmission part 62 and the output rotating body 50. At this time, it is a low-speed and high-torque output state.

[0071] The speed change assemblies 20 in the above embodiments are all two-stage speed change transmission assemblies. The speed change assembly 20 in the present invention can also be a three-stage speed change transmission assembly. A three-stage speed change transmission assembly is provided in this embodiment. Please refer to Figures 13 to 15, the difference between this three-stage speed-changing transmission assembly and the above-mentioned two-stage speed-changing transmission assembly lies in that: the driven member further includes a fifth transmission part 63 and a sixth transmission part 64 arranged coaxially. The fifth transmission part 63 and the fourth transmission part 62 are in a constant coupling state. The input rotating body 30 moving along the main shaft 13 can enable the input rotating body 30 to have two stopping positions. When the main shaft 13 rotates in the first direction, the input rotating body 30 stops at the first position. The input rotating body 30 is located at the top of the main shaft 13 and is in transmission coupling with the output rotating body 50. At this time, no power is transmitted between the sixth transmission part 64 in the driven member 60 and the output rotating body 50, and the input rotating body 30 is also in a separated state from the third transmission part 61 and the fourth transmission part 62 of the driven member 60. The main shaft 13 directly drives the output rotating body 50 to rotate through the input rotating body 30 and drives the output shaft 40 to rotate synchronously with the main shaft 13. At this time, the output shaft 40 outputs at a high speed and low torque. It can be understood that when the input rotating body 30 stops at the first position, the input rotating body 30 may also be in a contact coupling state with the third transmission part 61 or the fourth transmission part 62 of the driven member 60. When the main shaft 13 runs in the direction opposite to the first direction, the input rotating body 30 moves along the main shaft 13 and stops at the second position. At this time, the input rotating body 30 moves to the lower part of the main shaft 13. The input rotating body 30 is separated from the output rotating body 50, and the input rotating body 30 is in transmission coupling with the third transmission part 61 or the fourth transmission part 62, and the output rotating body 50 is in transmission coupling with the sixth transmission part 64. The input rotating body 30 transmits power to the fifth transmission part 63 through the third transmission part 61 and the fourth transmission part 62 of the driven member 60, and then transmits the power to the output rotating body 50 through the sixth transmission part 64, so that the output shaft 40 runs at a second speed. At this time, the output shaft 40 is in a low-speed and high-torque output state. Specifically, the fifth transmission part 63 and the sixth transmission part 64 may form an integral structure or a split structure.

[0072] This application provides a food processor. The output shaft 40 of the clutch speed-changing mechanism in its housing is connected to the processing cup assembly and drives the processing cup assembly to operate. The specific structure of the clutch speed-changing mechanism refers to all the technical solutions of the above-mentioned all embodiments. Since the electrical appliance adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one. Among them, the processing cup assembly can be, for example, a breaking cup assembly, a grinding cup assembly, a cooking cup assembly, a dough mixing cup assembly, etc. used for food processing on the market, and the executing component can be, for example, a stirring knife for high-speed stirring or a stirring rod for dough mixing.

[0073] Specifically, the food processor can have multiple working modes. In the first working mode, the drive motor 10 drives the clutch speed change mechanism, and then drives the processing cup assembly to operate at a speed range of 5000 rpm - 25000 rpm. In this mode, the food processor can achieve a high-speed operation breaking wall mode for crushing and whipping fruits and vegetables, for example. At this time, the processing execution part is the stirring blade.

[0074] In the second working mode, the drive motor 10 drives the clutch speed change mechanism, and then drives the processing cup assembly to operate at a speed range of 10000 rpm - 25000 rpm. In this mode, the food processor can perform a high-speed operation mode for grinding ingredients to obtain ingredient powders. In this mode, the processing execution part is the grinder.

[0075] In the third working mode, the drive motor 10 drives the clutch speed change mechanism, and then drives the processing cup assembly to operate at a speed range of 50 rpm - 1000 rpm. In this mode, it can be used for stirring viscous ingredients, such as kneading dough or mixing other ingredients. In this mode, the processing execution part is the stirring rod.

[0076] In the fourth working mode, the drive motor 10 drives the clutch speed change mechanism, and then drives the processing cup assembly to operate at a speed range of 20 rpm - 500 rpm. In this mode, it can be used for, for example, automatic stir-frying operation. At this time, the processing execution part 204 is the spatula.

[0077] As can be seen from the above, the food processor drives the main shaft 13 of the clutch speed change mechanism to rotate forward or reverse by the drive motor 10, and then drives the forward and reverse rotation of the processing cup assembly, which can enable the output shaft 40 to output different speeds and torques, realizing multiple working modes in the food processor.
