[0033] The present invention provides a food processor.

[0034] In an embodiment of the present invention, as Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8 shown, the food processor includes a clutch speed change mechanism 100, and the clutch speed change mechanism 100 includes a driving shaft 110, an input rotating body 120, an output shaft 130, an output rotating body 140 and a bearing 150; the input rotating body 120 is mounted on the driving shaft 110 and can rotate synchronously under the drive of the driving shaft 110, and the input rotating body 120 can move on the driving shaft 110; the output shaft 130 is spaced from and disposed at an angle to the driving shaft 110; the output rotating body 140 has at least two coaxially arranged coupling rings 142, and the diameter sizes of the at least two coaxially arranged coupling rings 142 are different; when the input rotating body 120 moves along the driving shaft 110, it has at least a first position and a second position; when the input rotating body 120 moves to the first position, the input rotating body 120 is in driving coupling with one of the coupling rings 142 to drive the output shaft 130 to rotate at a first speed; when the input rotating body 120 moves to the second position, the input rotating body 120 is in driving coupling with the other of the coupling rings 142 to drive the output shaft 130 to rotate at a second speed; the bearing 150 is sleeved outside the output shaft 130.

[0035] The driving shaft 110 in the present invention can be the motor shaft of a motor serving as a power source or a connecting shaft connected to the power source, and the driving shaft 110 can rotate under the drive of the power source. By mounting the input rotating body 120 on the driving shaft 110 and enabling it to rotate synchronously under the drive of the driving shaft 110, when the driving shaft 110 rotates, the effect of driving the input rotating body 120 to rotate can be achieved. Further, the clutch speed change mechanism 100 of the present invention further includes an output shaft 130 and an output rotating body 140, and the output rotating body 140 has at least two coupling rings 142 arranged coaxially; and since the input rotating body 120 can move on the driving shaft 110, when the input rotating body 120 moves to different positions along the driving shaft 110, the effect of being respectively in transmission coupling with different coupling rings 142 can be achieved. In addition, since the diameter sizes of at least two coupling rings 142 arranged coaxially are different, when the input rotating body 120 moves to positions corresponding to these two coupling rings 142 with different diameter sizes, the coupling rings 142 can drive the output shaft 130 to have different rotational speeds, thereby achieving the effect of clutch speed change. Specifically, it is defined that the coupling ring 142 includes a first coupling ring and a second coupling ring, the diameter size of the first coupling ring is larger than that of the second coupling ring, and when it is defined that the input rotating body 120 moves to the first position, it corresponds to and is in transmission coupling with the first coupling ring, so that at this time the first coupling ring rotates at a first rotational speed and drives the output shaft 130 to also rotate at the first rotational speed. When the input rotating body 120 moves to the second position, it corresponds to and is in transmission coupling with the second coupling ring, so that at this time the second coupling ring rotates at a second rotational speed and drives the output shaft 130 to also rotate at the first rotational speed. It can be understood that on the premise that the diameter size of the first coupling ring is larger than that of the second coupling ring, the above-mentioned first rotational speed is less than the second rotational speed, so that the clutch speed change mechanism 100 in the technical solution of the present invention can achieve the effect that the output shaft 130 outputs different rotational speeds by only using one input rotating body 120 and through one-stage transmission, and the clutch speed change mechanism 100 is simplified on the basis of being able to achieve a variable transmission ratio. In addition, at least two coupling rings 142 in the present invention are coaxially and fixedly connected, which improves the strength of any single coupling ring 142. Of course, at least two coupling rings 142 can only be guaranteed to be coaxially arranged, and they can be not fixedly connected together, so that when any one of the coupling rings 142 is worn or damaged, it is convenient for the user to replace only the worn or damaged coupling ring 142.

[0036] It should be noted that in the present invention, the output shaft 130 and the driving shaft 110 are arranged at intervals, so that the output shaft 130 and the driving shaft 110 are not on the same straight line and do not intersect at a point, so that the rotational states of the driving shaft 110 and the output shaft 130 do not interfere with each other. The output shaft 130 and the driving shaft 110 are arranged at an angle, so that the output shaft 130 and the driving shaft 110 can be perpendicularly arranged (such as Figure 1 、Figure 4 , Figure 6 or Figure 8 as shown), or may be set at an acute angle (such as Figure 7 as shown), so as to achieve the effect of changing the movement direction. It can be understood that when the output shaft 130 is perpendicular to the driving shaft 110, when the input rotating body 120 on the driving shaft 110 moves along the axial direction of the driving shaft 110, the plane thereof in transmission coupling with the coupling ring 142 remains unchanged. In order to ensure that at least two coupling rings 142 of the output rotating body 140 on the output shaft 130 can be in transmission coupling with the input rotating body 120 on the driving shaft 110, one of the coupling rings 142 can be sleeved outside the other coupling ring 142, so that at least two coupling rings 142 can be coaxially arranged along the radial direction of the output rotating body 140; or when at least two coupling rings 142 are coaxially arranged along the axial direction of the output shaft 130, the coupling part of the coupling ring 142 far from the driving shaft 110 can extend towards the driving shaft 110 and be flush with the coupling ring 142 close to the driving shaft 110, so as to ensure that when the input rotating body 120 on the driving shaft 110 moves to different positions, it can be in transmission coupling with at least two coupling rings 142 respectively. When the output shaft 130 is set at an acute angle with the driving shaft 110, the output shaft 130 has an end close to the driving shaft 110 and an end far from the driving shaft 110. At least two coupling rings 142 with different diameter sizes on the output shaft 130 can be arranged at intervals along the axial direction of the output shaft 130. The arrangement direction of the coupling ring 142 with a smaller diameter and the coupling ring 142 with a larger diameter can be set from the end of the output shaft 130 far from the driving shaft 110 to the end of the output shaft 130 close to the driving shaft 110, so as to ensure that when the input rotating body 120 moves on the driving shaft 110, it can be in transmission coupling with these two coupling rings 142 with different diameter sizes respectively. Of course, the output rotating body 140 may also have three coupling rings 142, four coupling rings 142 or more coupling rings 142. When the input rotating body 120 moves along the axial direction of the driving shaft 110, the input rotating body 120 has different positions respectively coupled with a plurality of different coupling rings 142, and then realizes driving the output rotating body 140 to rotate through different coupling rings 142, so as to achieve the effect of driving the output shaft 130 to rotate at a variable speed. Among them, it can be understood that only one input rotating body 140 can be provided in the technical solution of the present invention. By moving this one input rotating body 140 on the driving shaft, the transmission coupling effect with coupling rings 142 of different sizes can be realized, and further the effect of outputting different speed ratios through one-stage transmission can be realized through one input rotating body 140, reducing the setting of parts and the occupied space.

[0037] Specifically, when the input rotary body 120 moves on the driving shaft 110, it can directly drive the input rotary body 120 to make linear motion along the axial direction of the driving shaft 110 through the driving member, or the driving shaft 110 can be threadedly matched with the input rotary body 120 so that the driving shaft 110 can convert its rotary motion into linear motion of the input rotary body 120 on the driving shaft 110 during the rotation process. Furthermore, the input rotary body 120 can reciprocate on the driving shaft 110, so that different coupling rings 142 of the output rotary body 140 can be flexibly selected for transmission coupling. For example, the driving member may be a telescopic cylinder, so that when the driving member is connected to the input rotating body 120, it can drive the input rotating body 120 to make reciprocating linear motion along the axial direction of the driving shaft 110; or when the driving shaft 110 and the input rotating body 120 are threadedly matched, the direction of the linear motion of the input rotating body 120 driven by the driving shaft 110 along the axial direction of the driving shaft 110 when the driving shaft 110 rotates forward is opposite to the direction of the linear motion of the input rotating body 120 driven by the driving shaft 110 along the axial direction of the driving shaft 110 when the driving shaft 110 rotates reversely.

[0038] In order to ensure the stability of the rotation of the output shaft 130, the clutch transmission mechanism 100 of the present invention also includes a bearing 150 sleeved outside the output shaft 130, which can support the output shaft 130 to prevent the output shaft 130 from bending or moving in the radial direction. In addition, the setting of the bearing 150 also reduces the rotational friction of the output shaft 130 during the rotation process, thereby increasing the service life of the output shaft 130. Optionally, one or at least two bearings 150 may be provided. When at least two bearings 150 are provided, at least two bearings 150 may be respectively located on the side of the output rotor 140 facing the driving shaft 110 and the side away from the driving shaft 110, thereby also having a better limiting effect on the output rotor 140. Of course, in other embodiments, at least two bearings 150 may be both located on the side of the output rotor 140 facing the driving shaft 110, or at least two bearings 150 may be both located on the side of the output rotor 140 away from the driving shaft 110. It is understandable that, in order to ensure the stability of the rotation of the driving shaft 110, a bearing 150 may also be provided on the driving shaft 110, and the bearing 150 is sleeved outside the driving shaft 110, wherein the bearing 150 on the driving shaft 110 can be used as a limiter for the input rotating body 120 to move along the axial direction of the driving shaft 110, and a separate limiter may also be provided on the driving shaft 110 to limit the displacement of the input rotating body 120 to prevent the input rotating body 120 from escaping from the driving shaft 110. One bearing 150 may be provided on the driving shaft 110, or at least two bearings 150 may be provided at intervals to improve the supporting effect on the driving shaft 110.

[0039] The clutch and speed change mechanism 100 in the present invention can be a part of the internal structure of a cooking appliance or other types of electrical appliances. The above-mentioned driving shaft 110 and output shaft 130 can be mounted on the housing of the cooking appliance or other types of electrical appliances, and can be reasonably arranged with the parts inside the cooking appliance or other types of electrical appliances to form an integral body. Among them, the driving shaft 110 and the output shaft 130 can be mounted on different housing parts of the cooking appliance or other types of electrical appliances, or can be mounted on the housing in the same area. In the actual application process, when applied to an electrical appliance, for example, when applied to a cooking appliance, the input rotating body 120 can be transmission-coupled with the coupling ring 142 with a smaller diameter size to drive the output shaft 130 to rotate at a high speed, meeting the requirements such as juice whipping. When the input rotating body 120 is transmission-coupled with the coupling ring 142 with a larger diameter size, it is a state of driving the output shaft 130 to rotate at a low speed and with a large torque, which can meet heavy-duty operation scenarios such as dough kneading, thus meeting people's diverse usage requirements for the functions of electrical appliances.

[0040] In the technical solution of the present invention, by installing the input rotating body 120 on the driving shaft 110, the input rotating body 120 can move on the driving shaft 110 and has at least a first position and a second position during the movement; at the first position and the second position, the input rotating body 120 is respectively transmission-coupled with at least two coupling rings 142 with different diameter sizes of the output rotating body 140 to drive the output shaft 130 to rotate at a first speed and a second speed respectively, thereby further realizing the effect of variable-speed rotation of the output shaft 130. In addition, by arranging the output shaft 130 at an interval and at an angle with the driving shaft 110, on the one hand, it can ensure that when at least two coupling rings 142 with different diameter sizes are installed on the output shaft 130, the input rotating body 120 can be respectively moved to the first position and the second position and can be transmission-coupled with these two coupling rings 142 with different diameter sizes, so that the effect of variable speed can be achieved through one-stage transmission; on the other hand, it can also achieve the effect of changing the transmission direction through one-stage transmission. By sleeving the bearing 150 outside the output shaft 130, on the one hand, the bearing 150 can have a good supporting effect on the output shaft 130 and can reduce the rotational friction of the output shaft 130 during rotation; on the other hand, it also has a good limiting effect on the output rotating body 140.

[0041] In one embodiment, please refer to Figures 1 to 6 , the driving shaft 110 is perpendicularly arranged with the output shaft 130, and at least two coupling rings 142 are arranged radially along the output rotating body 140.

[0042] By vertically arranging the driving shaft 110 and the output shaft 130, the effect of variable-direction transmission can be achieved. And when the driving shaft 110 serves as the driving shaft of the motor, since the driving shaft 110 and the output shaft 130 are vertically arranged, when the output shaft 130 is arranged in the vertical direction, the driving shaft 110 can be arranged in the horizontal direction, so that the space occupied by the clutch speed change mechanism 100 in the vertical direction is small, and the overall height of the clutch speed change mechanism 100 is reduced. It can be understood that when the clutch speed change mechanism 100 is applied to the main body of some electrical appliances such as a cooking machine or a blender, compared with the way that the driving shaft 120 and the output shaft 130 in the traditional electrical appliance main body are coaxially connected through a coupling or other connection structures, the height of the electrical appliance main body applying the clutch speed change mechanism 100 in this embodiment can be set lower, thereby reducing the height and the occupied space size of the whole electrical appliance, and improving the stability of the whole machine during the working process of the clutch speed change mechanism 100.

[0043] Furthermore, under the setting mode where the driving shaft 110 and the output shaft 130 are vertically arranged, by arranging at least two coupling rings 142 along the radial direction of the output rotating body 140, the arrangement of the two coupling rings 142 can reduce the space they occupy in the axial direction of the output shaft 130. Further, the size of the output shaft 130 can be shortened, making the components of the whole clutch speed change mechanism 100 more compact, reducing the space size occupied by the whole clutch speed change mechanism 100 in the axial direction of the output shaft 130, and miniaturizing the whole clutch speed change mechanism 100.

[0044] Specifically, when at least two coupling rings 142 are coaxially arranged on the output shaft 130, at least two coupling rings 142 can be in a split form and are connected together by a connecting piece, for example, fixed together by a connecting key or by bonding or magnetic attraction. Or, at least two coupling rings 142 can be simultaneously fixed on the same side of the rotating base body. The rotating base body is sleeved outside the output shaft 130 and can drive the output shaft 130 to rotate.

[0045] In this embodiment, please continue to refer to Figures 1 to 5 , the output rotating body 140 further includes a connecting disk 141. The output shaft 130 passes through the connecting disk 141, and at least two coupling rings 142 with different diameter sizes are connected to the side of the connecting disk 141 facing the driving shaft 110.

[0046] By passing the output shaft 130 through the connecting disk 141 and connecting at least two coupling rings 142 with different diameter sizes to the side of the connecting disk 141 facing the driving shaft 110, at least two coupling rings 142 with different diameter sizes can be in transmission coupling with the input rotating body 120 on the side of the connecting disk 141 facing the driving shaft 110, thereby achieving the effect of driving the connecting disk 141 to rotate at different speeds. Finally, the connecting disk 141 drives the output shaft 130 to rotate at different speeds, realizing the coupling of the input rotating body 120 with different coupling rings 142 so that the clutch speed-changing mechanism 100 can output different speed ratios.

[0047] Specifically, in order to achieve the effect that the connecting disk 141 is sleeved outside the output shaft 130 and can drive the output shaft 130 to rotate, the cross-section of the output shaft 130 can be a non-circular cross-section. For example, its cross-section can be a D-shaped, rectangular, pentagonal or other irregular shape. The connecting disk 141 can be provided with a mounting hole having the same shape as the cross-section of the output shaft 130, and the size of the mounting hole is adapted to the size of the cross-section of the output shaft 130, so as to achieve the effect that the connecting disk 141 rotates to drive the output shaft 130 to rotate synchronously. Alternatively, the connecting disk 141 and the output shaft 130 can be connected by a key connection or a hub connection, thereby also achieving the effect that the connecting disk 141 rotates to drive the output shaft 130 to rotate synchronously. Since the key connection and the hub connection are conventional technical means for those skilled in the art, they will not be elaborated in detail here. In the present invention, as long as the effect that the connecting disk 141 can drive the output shaft 130 to rotate synchronously can be achieved.

[0048] In another embodiment, the driving shaft 110 and the output shaft 130 are arranged at an acute angle, and at least two coupling rings 142 are arranged along the axial direction of the output shaft 130; and from the end of the output shaft 130 close to the driving shaft 110 to the end of the output shaft 130 far from the driving shaft 110, the diameter size of the coupling ring 142 gradually increases. Or, as Figure 7 shown, the driving shaft 110 and the output shaft 130 are arranged at an obtuse angle, and at least two coupling rings 142 are arranged along the radial direction of the output shaft 130; and from the end of the output shaft 130 close to the driving shaft 110 to the end of the output shaft 130 far from the driving shaft 110, the diameter size of the coupling ring 142 gradually increases.

[0049] By setting the driving shaft 110 at an acute angle to the output shaft 130, the output shaft 130 has one end close to the driving shaft 110 and one end far from the driving shaft 110; similarly, the driving shaft 110 also has one end close to the output shaft 130 and one end far from the output shaft 130. By arranging at least two coupling rings 142 along the axial direction of the output shaft 130, and from the end of the output shaft 130 close to the driving shaft 110 to the end of the output shaft 130 far from the driving shaft 110, the diameter size of the coupling ring 142 gradually increases. When the input rotating body 120 moves on the driving shaft 110, when the input rotating body 120 moves to the end of the driving shaft 110 close to the output shaft 130, the distance from the input rotating body 120 to the output shaft 130 is short, and the diameter size of the coupling ring 142 corresponding to this position on the output shaft 130 is also small. Therefore, the input rotating body 120 can be in transmission coupling with the coupling ring 142 with a small diameter size here; when the input rotating body 120 moves to the end of the driving shaft 110 far from the output shaft 130, the distance from the input rotating body 120 to the output shaft 130 is large, and the diameter size of the coupling ring 142 corresponding to this position on the output shaft 130 is also large. Therefore, the input rotating body 120 can be in transmission coupling with the coupling ring 142 with a large diameter size here.

[0050] Alternatively, as Figure 7 shown, the driving shaft 110 is set at an obtuse angle to the output shaft 130, and at least two coupling rings 142 are arranged along the radial direction of the output shaft 130; and from the end of the output shaft 130 close to the driving shaft 110 to the end of the output shaft 130 far from the driving shaft 110, the diameter size of the coupling ring 142 gradually increases.

[0051] In the above embodiments, the coupling ring 142 can be a gear ring or an outer ring of a friction column, and the input rotating body 120 can also be a gear ring or an outer ring of a friction column. It should be noted that when the coupling ring 142 is a gear ring, the corresponding input rotating body 120 also selects a gear ring; when the coupling ring 142 is an outer ring of a friction column, the corresponding input rotating body 120 also selects an outer ring of a friction column.

[0052] Furthermore, please refer to Figure 2 and Figure 3 . To ensure the stability of the transmission coupling, the coupling ring 142 can be a gear ring, and the corresponding input rotating body 120 also selects a gear ring. Specifically, at least two coupling rings 142 are both crown gears; or at least two coupling rings 142 are both bevel gears.

[0053] With such a setting, when the driving shaft 110 and the output shaft 130 are arranged at an angle, the effect that the input rotating body 120 rotates to drive one of the coupling rings 142 to rotate can be ensured.

[0054] In this embodiment, please refer toFigure 1 and Figure 4 There are two coupling rings 142; on the driving shaft 110, a first limiting structure 160 and a second limiting structure 170 are arranged at intervals along its axial direction. The input rotating body 120 is arranged between the first limiting structure 160 and the second limiting structure 170 and moves between the first limiting structure 160 and the second limiting structure 170. When the input rotating body 120 moves to the first position, it abuts against the first limiting structure 160, and when the input rotating body 120 moves to the second position, it abuts against the second limiting structure 170.

[0055] By arranging the first limiting structure 160 and the second limiting structure 170 at intervals along the axial direction on the driving shaft 110, and the input rotating body 120 is arranged between the first limiting structure 160 and the second limiting structure 170 and moves between the first limiting structure 160 and the second limiting structure 170, when the input rotating body 120 moves to abut against the first limiting structure 160, it can be stopped by the first limiting structure 160, thereby preventing the input rotating body 120 from disengaging from the driving shaft 110 during the movement. Or when the input rotating body 120 moves to abut against the second limiting structure 170, it can be stopped by the second limiting structure 170, and the input rotating body 120 can also be prevented from disengaging from the driving shaft 110 during the movement.

[0056] Further, in order to enable the input rotating body 120 to be converted from a linear motion into a rotational motion that rotates with the first limiting structure 160 and the driving shaft 110 when the input rotating body 120 moves to abut against the first limiting structure 160, and further drive the output rotating body 140 and the output shaft 130 to rotate. In this embodiment, the first limiting structure 160 can correspond to one of the two coupling rings 142, so that when the input rotating body 120 moves to abut against the first limiting structure 160, the input rotating body 120 can be in transmission coupling with the coupling ring 142 corresponding to the first limiting structure 160. Similarly, the second limiting structure 170 can correspond to the other of the two coupling rings 142, so that when the input rotating body 120 moves to abut against the second limiting structure 170, the input rotating body 120 can be in transmission coupling with the coupling ring 142 corresponding to the second limiting structure 170.

[0057] Of course, it can be understood that in other embodiments, there may be multiple coupling rings 142, and the diameter sizes of the multiple coupling rings 142 are all different. A plurality of limiting structures may be provided on the driving shaft 110 corresponding to the multiple coupling rings 142, so that when the input rotating body 120 abuts against each limiting structure correspondingly, it can be in transmission coupling with a coupling ring 142 correspondingly, so that the clutch speed change mechanism 100 can achieve the effect of multiple transmission ratios. Specifically, when there are multiple limiting structures, the multiple limiting structures include a first limiting structure 160 and a second limiting structure 170 respectively provided at both ends, and the multiple limiting structures further include a third limiting structure, and the third limiting structure is provided between the first limiting structure 160 and the second limiting structure 170.

[0058] In order to ensure that the input rotating body 120 can slide freely between the first limiting structure 160 and the second limiting structure 170, that is, the input rotating body 120 can cross the third limiting structure during the movement process, the third limiting structure in this embodiment can be an elastic limiting structure. For example, the third limiting structure can be a spring piece provided on the driving shaft 110 or an elastic bead installed on the driving shaft 110. The elastic bead can be retracted into the driving shaft 110 under the action of an external force, and protrude from the outer surface of the driving shaft 110 in the natural state. The input rotating body 120 can be correspondingly provided with a card slot. When the input rotating body 120 needs to stay at the third limiting structure to be in transmission coupling with a coupling ring 142, when the input rotating body 120 passes through the third limiting structure during the movement process, it abuts against the third limiting structure and deforms, so that when the third limiting structure corresponds to the card slot of the input rotating body 120, it snaps into the card slot, and then the effect of clamping and fixing the third limiting structure and the input rotating body 120 together is realized. When the third limiting structure rotates with the driving shaft 110, it will also drive the input rotating body 120 to rotate, and then the effect of transmission coupling with a coupling ring 142 is realized, and then the effect of driving the output shaft 130 to rotate at a variable speed is realized. When the input rotating body 120 continues to move to drive the third limiting structure to deform, the third limiting structure can provide a space for avoidance for the input rotating body 120 to cross, so as to facilitate the input rotating body 120 to move between the first limiting structure 160 and the second limiting structure 170 through the third limiting structure.

[0059] Specifically, as Figure 1 or Figure 4 shown, the first limiting structure 160 is a first limiting ring, and the first limiting ring is fixedly sleeved outside the driving shaft 110.

[0060] By setting the first limiting structure 160 as the first limiting ring, the first limiting structure 160 is made relatively simple. The first limiting ring can be in a split form with the driving shaft 110. The first limiting ring is sleeved outside the driving shaft 110 and can be fixedly connected to the driving shaft 110 through a connecting member. Thus, when any one of the first limiting ring or the driving shaft 110 is damaged, only the damaged component needs to be replaced, thereby saving the replacement cost. Of course, the first limiting ring can also be integrally structured with the driving shaft 110, thereby improving the connection strength of the first limiting ring. For example, the first limiting ring can be integrally structured with the driving shaft 110 by welding, or the first limiting ring and the driving shaft 110 can be integrally structured by one-piece molding in a mold.

[0061] Alternatively, the first limiting structure 160 is a first convex block protruding from the driving shaft 110. With such a setting, the first limiting structure 160 can also be made relatively simple. By protruding the first convex block on the driving shaft 110, the connection strength between the first limiting structure 160 and the driving shaft 110 is higher, avoiding the phenomenon that the first convex block is easily damaged.

[0062] Similarly, as Figure 1 or Figure 4 shown, the second limiting structure 170 is a second limiting ring, and the second limiting ring is fixedly sleeved outside the driving shaft 110. By setting the second limiting structure 170 as the second limiting ring, the second limiting structure 170 is made relatively simple. The second limiting ring can be in a split form with the driving shaft 110. The second limiting ring is sleeved outside the driving shaft 110 and can be fixedly connected to the driving shaft 110 through a connecting member. Thus, when any one of the second limiting ring or the driving shaft 110 is damaged, only the damaged component needs to be replaced, thereby saving the replacement cost. Of course, the second limiting ring can also be integrally structured with the driving shaft 110, thereby improving the connection strength of the second limiting ring. For example, the second limiting ring can be integrally structured with the driving shaft 110 by welding, or the second limiting ring and the driving shaft 110 can be integrally structured by one-piece molding in a mold.

[0063] Alternatively, the second limiting structure 170 is a second convex block protruding from the driving shaft 110. With such a setting, the second limiting structure 170 can also be made relatively simple. By protruding the second convex block on the driving shaft 110, the connection strength between the second limiting structure 170 and the driving shaft 110 is higher, avoiding the phenomenon that the second convex block is easily damaged.

[0064] As Figure 1As shown, in order to achieve the effect that the input rotating body 120 can move axially along the driving shaft 110, the present invention provides an embodiment. In this embodiment, one of the driving shaft 110 and the input rotating body 120 is formed with a spiral groove 111 extending along its axial direction, and the other is formed with a guiding protrusion. The guiding protrusion is embedded in the spiral groove 111 and is in spiral cooperation with the spiral groove 111 to drive the input rotating body 120 to move axially along the driving shaft 110.

[0065] Specifically, a spiral groove 111 extending along the axial direction of the driving shaft 110 is formed on the driving shaft 110, and a corresponding guiding protrusion is provided on the input rotating body 120. The guiding protrusion is embedded in the spiral groove 111 and is in spiral cooperation with the spiral groove 111. Then, when the driving shaft 110 rotates, the guiding protrusion moves along the spiral line of the spiral groove 111 in the spiral groove 111, and then it can be converted into the movement of the input rotating body 120 moving axially along the driving shaft 110. Alternatively, a spiral groove 111 is formed on the inner wall of the input rotating body 120 facing the driving shaft 110, and a guiding protrusion corresponding to the driving shaft 110 is embedded in the spiral groove 111. Then, during the rotation of the driving shaft 110, it also simultaneously satisfies the state of moving in the spiral groove 111. Furthermore, the guiding protrusion can drive the input rotating body 120 to move axially along the driving shaft 110, that is, the effect of converting the rotation state of the driving shaft 110 into the axial movement state of the input rotating body 120 is achieved.

[0066] In addition, based on the above solution that the first limiting structure 160 and the second limiting structure 170 are provided on the driving shaft 110 and the input rotating body 120 moves between the first limiting structure 160 and the second limiting structure 170, combined with the solution that a spiral groove 111 extending along the axial direction of the driving shaft 110 is formed on the driving shaft 110, and a guiding protrusion is formed on the input rotating body 120, and the guiding protrusion is embedded in the spiral groove 111 and is in spiral cooperation with the spiral groove 111. In this embodiment, the first limiting structure 160 and the second limiting structure 170 can be respectively arranged at both ends of the spiral groove 111. Thus, the first limiting structure 160 and the second limiting structure 170 can play a better limiting effect during the spiral cooperation process of the input rotating body 120 and the driving shaft 110, and avoid the effect that the guiding protrusion of the input rotating body 120 escapes out of the spiral groove 111 during the movement in the spiral groove 111.

[0067] Please refer to Figure 4 and Figure 5 , in order to achieve the effect that the input rotating body 120 can move axially along the driving shaft 110 and the driving shaft 110 can also drive the input rotating body 120 to rotate, the present invention also provides another embodiment. In this embodiment, the driving shaft 110 is a non-cylindrical shaft, and the clutch speed change mechanism 100 further includes a driving member for driving the input rotating body 120 to move axially along the driving shaft 110.

[0068] By setting the driving shaft 110 as a non-cylindrical shaft, when the input rotor 120 is sleeved on the driving shaft 110, it can ensure that the input rotor 120 can rotate with the rotation of the driving shaft 110, and can also achieve the effect that the input rotor 120 can move along the axial direction of the driving shaft 110. In this embodiment, the driving shaft 110 is not provided with a spiral groove 111. In order to drive the input rotor 120 to move in its axial direction, the clutch transmission mechanism 100 in this embodiment further includes a driving member, which drives the input rotor 120 to move along the axial direction of the driving shaft 110.

[0069] Specifically, in order to enable the driving member to drive the input rotating body 120 to move on the driving shaft 110, the driving member has various structural forms. Among them, the driving member can drive the input rotating body 120 to move by mechanical drive. For example, the driving member can be a cylinder, and the cylinder has a piston rod. The extension direction of the piston rod can be consistent with the extension direction of the driving shaft 110. When the piston rod is connected to the input rotating body 120, when the piston rod performs telescopic movement, it can drive the input rotating body 120 to move along its axial direction. Or the driving member can be a lever, one end of which is in contact with the input rotating body 120, and the other end is used to be moved by the user, so that when the user moves the other end of the lever, it transmits its power to the input rotating body 120 in the manner of a lever principle, and moves the input rotating body 120 to move along the driving shaft 110; of course, the lever can also be driven by other electrical components. It should be noted that when the above-mentioned cylinder and lever are used to drive the input rotary body 120, it is necessary to ensure that the input rotary body 120 can only move along the axial direction of the driving shaft 110, and cannot make the input rotary body 120 rotate in the circumferential direction relative to the driving shaft 110. Specifically, the driving shaft 110 can be non-cylindrical, and the input rotary body 120 has a mounting hole for the driving shaft 110 to pass through and the shape and size of the driving shaft 110 are adapted.

[0070] like Figure 4 As shown, in order to achieve the effect of the driving member driving the input rotating body 120 to move on the active shaft 110, a non-mechanical driving method can also be used. In this embodiment, the driving member is an electromagnet 180, and two electromagnets 180 are provided. The two electromagnets 180 are respectively connected to the first limiting structure 160 and the second limiting structure 170.

[0071] When electromagnets 180 are energized with different currents, they generate forces in different directions. To achieve the repulsive and attractive effects on the input rotating body 120, electromagnets 180 can also be provided on the input rotating body 120. Thus, the electromagnets 180 on the input rotating body 120 interact with the electromagnets 180 provided on the first limiting structure 160 or the second limiting structure 170, so as to achieve the effect that the input rotating body 120 moves on the driving shaft 110. Alternatively, the input rotating body 120 itself is made of a magnetically conductive material. Thus, when the electromagnets 180 on the first limiting structure 160 or the second limiting structure 170 are energized, they have a repulsive or attractive effect on the input rotating body 120, and then the input rotating body 120 moves axially along the driving shaft 110 under this effect.

[0072] Of course, in other embodiments, the driving shaft 110 can be arranged inside the housing, and the two electromagnets 180 can be arranged on the housing instead of on the first limiting structure 160 and the second limiting structure 170, and the two electromagnets 180 are respectively arranged corresponding to the first limiting structure 160 and the second limiting structure 170, so that the two electromagnets 180 generate forces in different directions when energized with different currents. Thus, one of the electromagnets 180 can still achieve a repulsive effect on the input rotating body 120, and the other electromagnet 180 can still achieve an attractive effect on the input rotating body 120. Under the simultaneous action of the two electromagnets 180, the input rotating body 120 can still be driven to move axially along the driving shaft 110.

[0073] As Figure 1 or Figure 4 shown, the food processor further includes a motor body 200 and a driving shaft 210 installed on the motor. Among them, the motor body 200 and the clutch speed change mechanism 100 can be fixed together by the housing. The motor body 200 is a conventional motor structure. The motor body 200 includes a stator and a rotor structure. The rotor has a driving shaft 210. The driving shaft 210 is in transmission connection with the driving shaft 110, and the output shaft 130 is used to drive an external component. Alternatively, the driving shaft 210 is directly used as the driving shaft 110 to drive the output shaft 130 to rotate, and drive other components to move through the output shaft 130.

[0074] As Figure 8As shown in the figure, the food processor of the present invention may further include a power source, a processing execution member 300, and a clutch speed change mechanism 100. The power source is drivingly connected to the driving shaft 110, and the processing execution member 300 is drivingly connected to the output shaft 130. Among them, the food processor can be, for example, a wall breaker, a juicer, a blender, a noodle machine, etc. used for food processing on the market. The power source can be only a motor; or the power source includes a motor and a gear transmission assembly drivingly connected to the motor, and the gear transmission assembly is drivingly connected to the driving shaft 110 of the clutch speed change mechanism 100; or other power sources that can rotate the driving shaft 110. The processing execution member 300 can be, for example, a stirring knife, a dough mixing knife, a grinder, a stirring rod and other structures.

[0075] Further, the food processor further includes a main housing 400 and a container 500. The power source, the driving shaft 110, the input rotating body 120, the output shaft 130, the output rotating body 140 and the bearing 150 are all arranged in the main housing 400, and the processing execution member 300 is arranged in the container 500, and the container 500 is installed on the main housing 130.

[0076] Since the power source, the driving shaft 110, the input rotating body 120, the output shaft 130, the output rotating body 140 and the bearing 150 are all arranged in the main housing 400, the main housing 400 has a good protection effect on these components. By arranging the processing execution member 300 in the container 500, a good food processing effect is achieved, ensuring that the food in the container 500 can be fully processed by the processing execution member 300. By installing the container 500 on the main housing 130, it is convenient for the output shaft 130 to be drivingly connected to the processing execution member 300.

[0077] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
