[0110] Referring to FIG. 1 、 FIG. 2 、 FIGS. 10-12 , an embodiment of the present application provides a chef machine, which includes a base unit 200, a head unit 100, a driving unit 300 and a steering unit 400. The base unit 200 is provided with a base transmission assembly 210. The head unit 100 is rotatably connected to the base unit 200. The head unit 100 is provided with a head transmission assembly 110. The driving unit 300 is arranged in the base unit 200 or the head unit 100. The steering unit 400 includes a main body part 410 and a steering part 420 rotatably connected to the main body part 410. The main body part 410 is connected to the output end of the driving unit 300, and the main body part 410 is connected to the base transmission assembly 210 to transmit the rotary power of the driving unit 300 to the output end of the base transmission assembly 210. The output end of the base transmission assembly 210 is used to connect a stirring bowl 700. The steering part 420 is connected to the head transmission assembly 110 to transmit the rotary power to the output end of the head transmission assembly 110. The output end of the head transmission assembly 110 is used to connect a stirring tool 500. When the head unit 100 is closed relative to the base unit 200, the main body part 410 is connected to the steering part 420 to realize torque transmission. When the head unit 100 is opened relative to the base unit 200, the main body part 410 and the steering part 420 remain in a connected state, and the main body part 410 can be telescopic and the steering part 420 can rotate relative to the main body part 410.

[0111] Thus, when the head unit 100 needs to be opened to the maximum angle, the rotation of the steering portion 420 relative to the main body portion 410 in multiple directions is adapted to the rotation of the head unit 100, and the stretching operation of the main body portion 410 is adapted to the lifting of the head unit 100; correspondingly, when the head unit 100 needs to be closed, the steering portion 420 is reversely rotated relative to the main body portion 410, and the retraction operation of the main body portion 410 is adapted to the closing of the head unit 100. During the opening or closing of the head unit 100, the steering portion 420 is always connected with the main body portion 410, and the rotation cooperation between the main body portion 410 and the steering portion 420 and the stretching and retraction operation of the main body portion 410 play a certain guiding and limiting role for the opening or closing of the head unit 100, guaranteeing the reliability of the head unit 100 in the opened or closed state, without the alignment operation of the main body portion 410 and the steering portion 420, and reducing the operation difficulty.

[0112] Referring to FIGS. 10-14A As shown in the figure, in an embodiment, the main body portion 410 includes an upper assembly 411 and a lower assembly 412, the upper assembly 411 is rotationally connected with the steering portion 420, and the lower assembly 412 is connected with the base transmission assembly 210; when the head unit 100 is opened relative to the base unit 200, the upper assembly 411 is in the connected state with the steering portion 420, and the upper assembly 411 generates a sliding displacement relative to the lower assembly 412.

[0113] Thus, when the head unit 100 needs to be opened to the maximum angle, the rotation of the steering portion 420 relative to the main body portion 410 is adapted to the rotation of the head unit 100, and the relative sliding between the upper assembly 411 and the lower assembly 412, for example, the upward displacement of the upper assembly 411 relative to the lower assembly 412, is adapted to the lifting of the head unit 100; correspondingly, when the head unit 100 needs to be closed, the steering portion 420 is reversely rotated relative to the main body portion 410, and the upper assembly 411 is downwardly displaced relative to the lower assembly 412, which is adapted to the closing of the head unit 100. During the opening or closing of the head unit 100, the steering portion 420 is always connected with the main body portion 410, and the rotation cooperation between the main body portion 410 and the steering portion 420 and the sliding cooperation between the upper assembly 411 and the lower assembly 412 play a certain guiding and limiting role for the opening or closing of the head unit 100, guaranteeing the reliability of the head unit 100 in the opened or closed state, without the alignment operation of the main body portion 410 and the steering portion 420, and reducing the operation difficulty.

[0114] Referring to FIG. 14AAs shown, in some embodiments, when the head unit 100 is closed relative to the base unit 200, the central axis of the main body portion 410 is collinear with the central axis of the steering portion 420, i.e. both the main body portion 410 and the steering portion 420 are in a vertical state. When the head unit 100 is slowly opened relative to the base unit 200, the head unit 100 undergoes an angular change, which in turn causes the steering portion 420 to rotate relative to the upper assembly 411, while the upper assembly 411 slides relative to the lower assembly 412 until the head unit 100 is opened to the maximum angle. Correspondingly, the central axis of the main body portion 410 is at an angle to the central axis of the steering portion 420, as shown in FIG. 1C. FIG. 13 As shown.

[0115] As shown, in some embodiments, one of the upper assembly 411 and the lower assembly 412 is configured with a receiving groove 4121, and the other is configured with a sliding shaft 4111 that is slidingly connected to the receiving groove 4121. For example, in the embodiment shown in FIG. 1A, the lower assembly 412 is configured with the receiving groove 4121, and the lower end of the upper assembly 411 forms the sliding shaft 4111 that is inserted into the receiving groove 4121. Of course, in other embodiments, the positions of the sliding shaft and the receiving groove can be interchanged, i.e. the sliding shaft is provided on the lower assembly and the receiving groove is provided on the upper assembly. FIGS. 10-14A As shown, in some embodiments, when the head unit 100 is closed relative to the base unit 200, the central axis of the main body portion 410 is collinear with the central axis of the steering portion 420, i.e. both the main body portion 410 and the steering portion 420 are in a vertical state. When the head unit 100 is slowly opened relative to the base unit 200, the head unit 100 undergoes an angular change, which in turn causes the steering portion 420 to rotate relative to the upper assembly 411, while the upper assembly 411 slides relative to the lower assembly 412 until the head unit 100 is opened to the maximum angle. Correspondingly, the central axis of the main body portion 410 is at an angle to the central axis of the steering portion 420, as shown in FIG. 1C.

[0116] As shown, in some embodiments, one of the upper assembly 411 and the lower assembly 412 is configured with a receiving groove 4121, and the other is configured with a sliding shaft 4111 that is slidingly connected to the receiving groove 4121. For example, in the embodiment shown in FIG. 1A, the lower assembly 412 is configured with the receiving groove 4121, and the lower end of the upper assembly 411 forms the sliding shaft 4111 that is inserted into the receiving groove 4121. Of course, in other embodiments, the positions of the sliding shaft and the receiving groove can be interchanged, i.e. the sliding shaft is provided on the lower assembly and the receiving groove is provided on the upper assembly. FIGS. 10-14A As shown, in some embodiments, one of the upper assembly 411 and the lower assembly 412 is configured with a receiving groove 4121, and the other is configured with a sliding shaft 4111 that is slidingly connected to the receiving groove 4121. For example, in the embodiment shown in FIG. 1A, the lower assembly 412 is configured with the receiving groove 4121, and the lower end of the upper assembly 411 forms the sliding shaft 4111 that is inserted into the receiving groove 4121. Of course, in other embodiments, the positions of the sliding shaft and the receiving groove can be interchanged, i.e. the sliding shaft is provided on the lower assembly and the receiving groove is provided on the upper assembly. FIG. 14A As shown, in some embodiments, one of the upper assembly 411 and the lower assembly 412 is configured with a receiving groove 4121, and the other is configured with a sliding shaft 4111 that is slidingly connected to the receiving groove 4121. For example, in the embodiment shown in FIG. 1A, the lower assembly 412 is configured with the receiving groove 4121, and the lower end of the upper assembly 411 forms the sliding shaft 4111 that is inserted into the receiving groove 4121. Of course, in other embodiments, the positions of the sliding shaft and the receiving groove can be interchanged, i.e. the sliding shaft is provided on the lower assembly and the receiving groove is provided on the upper assembly.

[0117] Understandably, when the head unit 100 is in the open state, the upper component 411 is extended relative to the lower component 412. When the head unit 100 is in the working state, the upper component 411 is within the receiving groove 4121, and torque is transmitted through the close cooperation between the upper component 411 and the lower component 412. During the opening or closing process of the body unit 100, the extension direction of the main body 410 remains unchanged, that is, only sliding displacement occurs between the upper component 411 and the lower component 412, and no change in angle occurs.

[0118] like FIG. 18 As shown, in one embodiment, the lower component 412 is constructed with a receiving groove 4121, and the lower end of the upper component 411 forms a sliding shaft 4111. Taking this example, the lower component 412 is connected to the base transmission component 210. When the machine head unit 100 is in the working position, there is a gap between the bottom of the sliding shaft 4111 and the bottom wall of the receiving groove 4121, and the gap is 1mm-5mm. When the machine head unit 100 switches from the working position to the open position (the machine head unit 100 is at the maximum opening angle), the upper component 411 moves upward relative to the lower component 412 by 50mm-60mm, that is, the sliding shaft 4111 moves upward within the receiving groove 4121 by 50mm-60mm. It can be seen that the steering unit 420 is always connected to the upper component 411, and the upper component 411 is also always connected to the lower component 412. The opening of the machine head unit 100 is achieved through the sliding fit between the upper component 411 and the lower component 412, and the rotational fit between the upper component 411 and the steering unit 420. When the machine head unit 100 is closed, the torque is transmitted through the docking of the upper component 411 and the lower component 412. The opening and closing operation of the machine head unit 100 is more convenient.

[0119] See FIGS. 10-14A As shown, in one embodiment, one of the sliding shaft 4111 and the receiving groove 4121 is provided with a first engaging portion, and the other is provided with a first mating portion for engaging with the first engaging portion. For example, in the attached... FIG. 14A In the illustrated embodiment, the first engaging portion is constructed as a engaging protrusion 4112 radially protruding from the outer surface of the sliding shaft 4111, and the first mating portion is constructed as a engaging groove 4122 radially recessed from the wall of the receiving groove 4121. Through the engaging engagement of the engaging protrusion 4112 and the engaging groove 4122, a tight fit between the upper component 411 and the lower component 412 is achieved, thereby realizing torque transmission. Furthermore, the sliding shaft 4111 has multiple engaging protrusions 4112 along its circumference; the wall of the receiving groove 4121 is provided with multiple engaging grooves 4122, with each engaging protrusion 4112 corresponding to one engaging groove 4122. By providing multiple engaging protrusions 4112 and multiple engaging grooves 4122, the connection tightness between the upper component 411 and the lower component 412 is improved, further enhancing the torque transmission effect between them.

[0120] In other embodiments, the sliding shaft outer surface can also be configured with a clamping groove, and the accommodation groove wall is configured for clamping with the clamping protrusion.

[0121] Referring to FIGS. 14B-14C As shown in an embodiment, the accommodation groove 4121 is configured on the lower assembly 412, and the sliding shaft 4111 is configured on the upper assembly 411. Correspondingly, the sliding shaft 4111 is rotationally connected with the turning part 420 at one end along the axial direction of the sliding shaft 4111, and the sliding shaft 4111 is connected with the base transmission assembly 210 at the other end along the axial direction of the sliding shaft 4111. In this way, the sliding connection between the upper assembly 411 and the lower assembly 412 is achieved, and the upward displacement of the upper assembly 411 relative to the lower assembly 412 is achieved to adapt to the lifting of the handpiece unit 100. The power transmission between the upper end of the upper assembly 411 and the turning part 420 is achieved, and the power transmission between the lower end of the upper assembly 411 and the base transmission assembly 210 is achieved.

[0122] Referring to FIGS. 14B-14C As shown in an embodiment, the lower assembly 412 is configured with a limiting groove 4123 in communication with the accommodation groove 4121, and the limiting groove 4123 is arranged in the vertical direction. The sliding shaft 4111 is connected with a limiting shaft 4113 in the radial direction of the sliding shaft 4111, and the limiting shaft 4113 is arranged in the limiting groove 4123 and can move in the vertical direction in the limiting groove 4123. The upward displacement of the upper assembly 411 relative to the lower assembly 412 is achieved by sliding the limiting shaft 4113 upward in the limiting groove 4123 to adapt to the lifting of the handpiece unit 100.

[0123] Referring to FIGS. 14B-14C As shown in an embodiment, the limiting shaft 4113 is arranged in the sliding shaft 4111. That is, the limiting shaft 4113 and the sliding shaft 4111 are two independent parts, which facilitates the assembly of the limiting shaft 4113 and the sliding shaft 4111. The sliding connection between the upper assembly 411 and the lower assembly 412 is achieved by arranging the limiting shaft 4113 in the sliding shaft 4111 and in the limiting groove 4123. Understandably, the extension length of the limiting groove 4123 determines the movement range of the limiting shaft 4113. In other embodiments, the limiting shaft 4113 can not be arranged in the sliding shaft 4111, but can extend radially outward from the outer peripheral wall of the sliding shaft 4111 to form a protruding limiting shaft 4113. In some embodiments, the limiting shaft 4113 passes through the limiting groove 4123 and protrudes from the lower assembly 412, that is, the length of the limiting shaft 4113 is greater than the outer diameter of the lower assembly 412. On the one hand, it is convenient for the limiting shaft 4113 to pass through the lower assembly 412, which improves the assembly efficiency. On the other hand, it can also reduce the risk of the limiting shaft 4113 disengaging from the limiting groove 4123, which improves the reliability of the sliding connection between the upper assembly 411 and the lower assembly 412.

[0124] Referring to FIGS. 13-14AIn one embodiment, at least one of the upper assembly 411 and the steering portion 420 is configured with a pivot shaft 422, and the other is pivotally connected with the pivot shaft 422. Through the pivot shaft 422, the upper assembly 411 and the steering portion 420 are pivotally connected, i.e. the steering portion 420 is pivoted relative to the upper assembly 411, thereby adapting to the opening operation of the handpiece unit 100.

[0125] In one embodiment, the pivot shaft is arranged on only one of the upper assembly or the steering portion, for example, the pivot shaft is arranged on the upper assembly and penetrates the steering portion, so that the steering portion can be pivoted about the pivot shaft, thereby adapting to the opening of the handpiece unit. In another embodiment, the pivot shaft can also be arranged on the steering portion and penetrate the upper assembly, and the steering portion can still be pivoted about the pivot shaft, thereby realizing the opening of the handpiece unit.

[0126] Referring to FIGS. 11-14A In another embodiment, the upper assembly 411 and the steering portion 420 are both configured with two spaced pivot ends 421, and the pivot shaft 422 penetrates the two pivot ends 421. For example, in the embodiment shown in the drawings, the upper assembly 411 and the steering portion are both provided with the pivot ends 421 at the connection positions, and the two pivot ends 421 enclose a U-shaped slot, so that the upper assembly 411 and the steering portion 420 are penetrated and matched with each other. The extension direction of the pivot shaft 422 of the upper assembly 411 intersects with the extension direction of the pivot shaft 422 of the steering portion 420. In this way, not only can the steering portion 420 be pivoted about its own pivot shaft 422 relative to the upper assembly 411, but also the upper assembly 411 can be pivoted about its own pivot shaft 422 relative to the steering portion 420, so that the steering portion 420 can be pivoted in any direction relative to the upper assembly 411, i.e. the handpiece unit 100 has a larger movement range, which adapts to the actual opening requirement of the handpiece unit 100 and reduces the matching precision requirement.

[0127] Referring to FIGS. 13-14A In one embodiment, the pivot ball 423 is arranged between the upper assembly 411 and the steering portion 420, and the two spaced pivot ends 421 of the upper assembly 411 are located on opposite sides of the pivot ball 423 along a first direction; the two spaced pivot ends 421 of the steering portion 420 are located on opposite sides of the pivot ball 423 along a second direction, for example FIG. 14AAs shown, the two spaced-apart pivot connection ends 421 of the upper assembly 411 are respectively located on the left and right sides of the pivot ball 423, and the two spaced-apart pivot connection ends 421 of the steering portion 420 are respectively located on the front and back sides of the pivot ball 423. Correspondingly, the front and back sides, and the left and right sides of the pivot ball 423 are respectively provided with pivot shafts 422 for rotationally connecting with the steering portion 420 and the upper assembly 411, so as to realize the arbitrary direction rotation of the steering portion 420 relative to the upper assembly 411. Through the cooperation of the pivot ball 423 and the plurality of pivot shafts 422, the steering portion 420 has a larger movement angle, which can adapt to the opening requirement of the head unit 100, and at the same time, can also reduce the cooperation precision requirement, etc.

[0128] In an embodiment, the transmission ratio of the head transmission assembly 110 is different from the transmission ratio of the base transmission assembly 210. Specifically, by rotating the steering portion 420 relative to the main body portion 410 in the steering unit 400, the head unit 100 can be opened relative to the base unit 200, that is, the head unit 100 can be in an open state. When the head unit 100 is in a closed state, that is, in a working process, the rotational power of the driving unit 300 is transmitted to the stirring tool 500 through the head transmission assembly 110, and the rotational power of the driving unit 300 is transmitted to the stirring bowl 700 through the base transmission assembly 210, and the transmission ratios of the head transmission assembly 110 and the base transmission assembly 210 are different. In this way, the stirring tool 500 and the stirring bowl 700 not only can rotate in the same direction, but also form a speed difference between them, that is, double rotational speed, so that in the stirring process, the stirring bowl 700 can continuously send the food materials to the working area of the stirring tool 500, and the stirring tool 500 can fully contact with the food materials in the stirring bowl 700, so that the stirring and mixing effect is good.

[0129] Taking the stirring tool 500 as a dough hook 520 as an example, the stirring bowl 700 in the prior art is fixed, which causes the dough hook 520 to only rotate in a certain area and cannot uniformly mix the dough in the entire stirring bowl 700, so that the effective dough forming effect is poor. However, through the same direction rotation of the dough hook 520 and the stirring bowl 700 and the speed difference between them, the stirring tool 500 can fully contact with the food materials in the stirring bowl 700 to improve the dough forming effect and the dough mixing effect.

[0130] As FIG. 18As shown, in one embodiment, the transmission ratio of the head transmission assembly 110 is less than that of the base transmission assembly 210, so that the rotational speed of the stirring tool 500 is greater than that of the stirring bowl 700, and thus in the stirring process, the stirring bowl 700 can continuously send food materials to the working area of the stirring tool 500, the stirring tool 500 can be in full contact with the food materials in the stirring bowl 700, and the stirring and mixing effect is good. In this embodiment, the rotational speed of the stirring tool 500 can reach 60 rpm-345 rpm, and the rotational speed of the stirring bowl 700 can reach 8 rpm-49 rpm. It can be understood that when the gathering piece 600 is further provided on one side of the stirring tool 500, the gathering piece 600 is always fixed, and the stirring tool 500 can rotate under the driving of the head transmission assembly 110.

[0131] In an embodiment, the driving unit is arranged in the head unit, and the power output end of the driving unit is coaxially connected with the turning part. For example, the center of the driving output wheel of the driving unit is provided with a connecting shaft, and the end of the turning part away from the main body part is provided with a matching hole. The driving unit is connected with the turning part through the close connection of the connecting shaft and the matching hole, so as to transmit the power of the driving unit to the turning part, and realize the transmission of torque. The input end of the head transmission assembly can be coaxially connected with the turning part, so as to transmit the power of the driving unit transmitted to the turning part to the head transmission assembly, and realize the rotation of the stirring tool. The input end of the base transmission assembly can be connected with the lower assembly in the main body part, so as to transmit the power of the driving unit transmitted to the turning part to the base transmission assembly through the main body part, and realize the rotation of the stirring bowl.

[0132] In another embodiment, referring to FIGS. 17-18 As shown, the driving unit 300 is arranged in the base unit 200, the lower assembly 412 is connected to the output end of the driving unit 300 and connected with the base transmission assembly 210. In this way, the power of the driving unit 300 is transmitted to the base transmission assembly 210 through the lower assembly 412, so as to drive the stirring bowl 700 to rotate; the power of the driving unit 300 is sequentially transmitted to the head transmission assembly 110 through the lower assembly 412, the upper assembly 411 and the turning part 420, so as to drive the stirring tool 500 to rotate.

[0133] Referring to FIGS. 17-18As shown, in one of the embodiments, the driving unit 300 comprises a driving member 310 and a driving pulley assembly 320; the driving pulley assembly 320 comprises a driving input wheel 321, a driving output wheel 322 and a driving transmission belt 323, the driving input wheel 321 and the driving output wheel 322 are both gears, and the driving transmission belt 323 is a belt, the power transmission is achieved through the engagement transmission of the driving input wheel 321, the driving output wheel 322 and the driving transmission belt 323; the driving input wheel 321 is connected to the output end of the driving member 310; the driving output wheel 322 is connected with the main body part 410. Further, a reduction gearbox 330 is also arranged between the driving member 310 and the driving pulley assembly 320, the reduction gearbox 330 comprises at least one set of reduction gears. In this way, the power of the driving member 310 is first transmitted to the reduction gears in the reduction gearbox 330 to achieve one-stage reduction, and then transmitted to the driving pulley assembly 320 to achieve two-stage reduction, and then transmitted to the head transmission assembly 110 and the base transmission assembly 210. In one embodiment, the number of teeth of the driving output wheel 322 can be 40-60, the number of teeth of the driving input wheel 321 can be 15-20, the transmission ratio of the driving pulley assembly 320 is 2-4, and the driving member 310 can be a motor in particular.

[0134] Referring to FIG. 12 As shown, the base transmission assembly 210 comprises a base input wheel 211, a base output wheel 212 and a base transmission belt 213, the base input wheel 211 is connected with the main body part 410, and the base output wheel 212 is used to connect the stirring bowl 700. The three-stage reduction is achieved through the base transmission assembly 210 to transmit the rotating power of the driving unit 300 to the stirring bowl 700. It can be understood that the rotating direction of the stirring bowl 700 is the same as the steering direction of the driving member 310, and changes with the steering direction of the driving member 310. In one embodiment, the number of teeth of the base output wheel 212 can be 100-200, the number of teeth of the base input wheel 211 can be 10-20, and the transmission ratio of the base transmission assembly 210 is 5-20.

[0135] Referring to FIG. 11 As shown, the head transmission assembly 110 comprises a head input wheel 111, a head output wheel 112 and a head transmission belt 113, the head input wheel 111 is connected with the steering part 420, and the head output wheel 112 is used to connect the stirring tool 500. The three-stage reduction is achieved through the head transmission assembly 110 to transmit the rotating power of the driving unit 300 to the stirring tool 500. In one embodiment, the number of teeth of the head output wheel 112 can be 30-48, the number of teeth of the head input wheel 111 can be 20-28, and the transmission ratio of the head transmission assembly 110 is 1.07-2.4. So that the rotating speed ratio of the stirring tool 500 and the stirring bowl 700 is greater than a preset value, for example, the rotating speed ratio is greater than 6-8, which is beneficial to the dough forming effect of pizza and the like.

[0136] Referring toFIG. 17 As shown in the drawings, in one of the embodiments, a magnetic ring 325 is connected to the driving input wheel 321, and the base unit 200 is provided with a Hall sensor for sensing the magnetic field change of the magnetic ring 325, so as to realize the rotation speed measurement of the driving input wheel 321. Specifically, the driving output wheel 322 is connected with a fixing frame 324, and the magnetic ring 325 is fixed to the fixing frame 324. The fixing frame 324 is provided with a plurality of positioning portions 3241 distributed in the circumferential direction, and the positioning portions 3241 are inserted and matched with the driving input wheel 321. For example, in the embodiment, the positioning portions 3241 are positioning ribs, and correspondingly, the driving input wheel 321 is provided with positioning holes matched with the positioning ribs. In other embodiments, the driving input wheel 321 can be provided with positioning ribs, and the fixing frame 324 can be provided with positioning holes, etc.

[0137] Referring to FIG. 8 and FIG. 9A As shown in the drawings, in one of the embodiments, the base unit 200 includes a support plate 220, and the base transmission assembly 210 and the driving unit 300 are both mounted to the support plate 220, so as to support and fix the driving unit 300 and the base transmission assembly 210 through the support plate 220, and ensure the stability of the transmission. Further, a damping pad 221 is arranged between the support plate 220 and the driving unit 300, and the damping pad 221 absorbs and dissipates vibration energy through the elastic material itself, so as to reduce the vibration transmission, which can be made of rubber, silicone or polyurethane, etc.

[0138] Referring to FIGS. 7-9A As shown in the drawings, in one of the embodiments, the base unit 200 further includes a transmission seat assembly 230 mounted to the support plate 220, and the transmission seat assembly 230 includes a first transmission seat 231 connected to the head transmission assembly 110, and the first transmission seat 231 is provided with a first mounting groove 2321, and the stirring bowl 700 is detachably connected to the first mounting groove 2321. In this way, the disassembly and assembly of the stirring bowl 700 can be facilitated. Specifically, the first transmission seat 231 can be rotatably mounted to the support plate 220 through a bearing, for supporting and guiding the rotation of the first transmission seat 231 relative to the support plate 220, and reducing the abrasion. Further, a damping silicone member can be arranged between the support plate 220 and the first transmission seat 231. The output end of the aforementioned base transmission assembly 210, i.e. the base output wheel 212, can be locked on the first transmission seat 231 through fasteners such as screws, etc., so that the base output wheel 212 can drive the first transmission seat 231 and the stirring bowl 700 connected to the first transmission seat 231 to rotate synchronously, and improve the reliability of the force transmission.

[0139] Referring to FIGS. 7-9AAs shown, in one of the embodiments, the first transmission seat 231 is provided with a first insert 232, the first insert 232 is internally provided with a first mounting groove 2321, and the first mounting groove 2321 is provided with a first notch 2322; the stirring bowl 700 is provided with a protruding portion 710 radially outward, when the stirring bowl 700 is in the unlocking position, the protruding portion 710 corresponds to the first notch 2322, so that the protruding portion 710 can be axially separated from the first mounting groove 2321, that is, the stirring bowl 700 can be removed. When the stirring bowl 700 is in the locked position, the protruding portion 710 is misaligned with the first notch 2322, that is, the protruding portion 710 is clamped with the groove wall of the first mounting groove 2321, the movement of the protruding portion 710 in the axial direction is limited by the groove wall of the first mounting groove 2321, so that the protruding portion 710 cannot be separated from the first mounting groove 2321, and the locking connection of the stirring bowl 700 and the first transmission seat 231 is realized. By operating the stirring bowl 700, it can be rotated to the unlocking position or the locked position. The first insert 232 can be made of plastic material, since the first transmission seat 231 and the stirring bowl 700 are both metal parts, by installing the first insert 232 made of plastic material on the first transmission seat 231, the first transmission seat 231 and the stirring bowl 700 are isolated, so as to solve the friction noise between the stirring bowl 700 and the first transmission seat 231. The mutual rotation of metal and metal will produce noise, the installation of the first insert 232 made of plastic material makes the protruding portion 710 rotate more smoothly in contact with the plastic part during movement.

[0140] Referring to FIGS. 7-9A As shown, in one of the embodiments, the first insert 232 is slidably connected with a bowl locking portion 233 in the radial direction, the bowl locking portion 233 protrudes from the groove wall of the first mounting groove 2321 in the radial direction, so that the protruding portion 710 will abut against the bowl locking portion 233 during rotation and push the bowl locking portion 233 to move outward in the radial direction. The first transmission seat 231 is provided with a first positioning column 2311 in the axial direction, the first positioning column 2311 is sleeved with a positioning elastic member 2312, one end of the positioning elastic member 2312 abuts against the transmission seat, and the other end is clamped to the bowl locking portion 233. Thus, when the protruding portion 710 pushes the bowl locking portion 233 to slide outward, the positioning elastic member 2312 will be compressed, and when the protruding portion 710 rotates to separate from the bowl locking portion 233, the bowl locking portion 233 will move inward in the radial direction under the action of the positioning elastic member 2312 and reset.

[0141] Specifically, when the stirring bowl 700 is in the unlocked position, that is, the protruding portion 710 corresponds to the first gap 2322, the stirring bowl 700 is manually operated to rotate clockwise, and the protruding portion 710 of the stirring bowl 700 will rotate to abut against the bowl locking portion 233. As the stirring bowl 700 continues to rotate, the bowl locking portion 233 will be pushed to retreat radially outward, and after sliding to the limit position, as the stirring bowl 700 continues to rotate, the protruding portion 710 will be disengaged from the abutment with the bowl locking portion 233. The bowl locking portion 233 is reset under the action of the positioning elastic member 2312 until the stirring bowl 700 rotates to the abutment of the protruding portion 710 with the extension end of the first installation groove 2321, and the stirring bowl 700 reaches the locked position. When the stirring bowl 700 rotates counterclockwise from the locked position, the protruding portion 710 of the stirring bowl 700 will push the bowl locking portion 233 abutting against it to slide and retreat radially outward, and after sliding to the limit position, as the stirring bowl 700 continues to rotate, the protruding portion 710 will be disengaged from the bowl locking portion 233. The bowl locking portion 233 is reset under the pressure of the positioning elastic member 2312, and the protruding portion 710 of the stirring bowl 700 rotates to the first gap 2322 of the first installation groove 2321. At this time, the stirring bowl 700 reaches the unlocked position, so the stirring bowl 700 can be removed from the first transmission seat 231. During the rotation of the protruding portion 710, the abutment of the protruding portion 710 with the bowl locking portion 233 and the pushing of the bowl locking portion 233 to move radially can provide tactile feedback to the operator, improving the feel when the stirring bowl 700 is assembled and disassembled. Among them, the number of bowl locking portions 233, first inserts 232 and positioning elastic members 2312 is the same, and one-to-one correspondence, the more the number, the more stable the locking effect between the first transmission seat 231 and the stirring bowl 700, and the stirring bowl 700 runs more stably during rotation with the first transmission seat 231, and is not easy to shake. Referring to FIGS. 9A-9C As shown, the aforementioned first insert 232 and bowl locking portion 233 and other components can be conveniently assembled on the first transmission seat 231, thereby forming a whole transmission seat assembly 230. In this way, the transmission seat assembly 230 can be installed as a whole in the base unit 200, which is more convenient to assemble and is convenient for maintenance later. The output end of the aforementioned base transmission assembly 210, that is, the base output wheel 212, can be locked on the first transmission seat 231 by fasteners such as screws, etc., so that the base output wheel 212 can drive the first transmission seat 231 and the stirring bowl 700 connected to the first transmission seat 231 to rotate synchronously, improving the reliability of force transmission.

[0142] Further, referring to FIGS. 7-9A As shown, a wear-resistant gasket 234 is provided between the first transmission seat 231 and the stirring bowl 700, which isolates the first transmission seat 231 and the stirring bowl 700, and plays a role in preventing scratching and eliminating friction noise.

[0143] Referring to FIG. 2 ,FIGS. 18-19 As shown, in one embodiment, the bottom of the mixing bowl 700 is flat, and the food processor also includes a gathering member 600 located on one side of the mixing tool 500. The axis of the gathering member 600 is parallel to the axis of the mixing tool 500. The gathering member 600 includes a fixing part 610 and an intercepting part 620. The fixing part 610 fixes the gathering member 600 to the head unit 100, that is, the gathering member 600 will not rotate and remains fixed to the head unit 100. The fixing part 610 can be conical. The bottom of the intercepting part 620 can abut against the inner bottom wall of the mixing bowl 700, thereby effectively gathering the ingredients in the mixing bowl 700.

[0144] Taking the mixing tool 500 as a dough hook 520 as an example, the gathering component 600 is a dough-blocking rod 602. The dough-blocking rod 602 blocks and intercepts the dough, preventing it from rotating with the mixing tool 500 and improving mixing efficiency. When the mixing tool 500 is a whisk 510, the gathering component 600 is a scraper 601. The whisk 510 has a 2mm-3mm gap from both the bottom wall and the inner side wall of the mixing bowl 700. The distance between the axis of the whisk 510 and the axis of the mixing bowl 700 is 55.6mm, and the maximum external dimension of the whisk 510 is 94mm. The distance between the axis of the scraper 601 and the axis of the mixing bowl 700 is 7.3mm, and the scraper 601 and the whisk 510 are located on the same side of the axis of the mixing bowl 700. The scraper 601 has a 2mm to 3mm gap between its surface and the wire portion of the beater 510 to prevent accidental collision during the beating cage 510's operation and rotation. Along the vertical direction (e.g.) FIG. 19 As shown in the Y direction, the bottom of the scraper 601 is in contact with the inner bottom wall of the mixing bowl 700. Therefore, the scraper 601 can intercept all the ingredients, and the ingredients will accumulate on the inside of the scraper 601 (towards the whisk 510). This allows the whisk 510 to fully contact the ingredients, so the whisk 510 can operate at a lower speed. The reduced speed not only greatly improves the noise during the operation of the whole machine, but also reduces the requirements for the drive unit 300, thus reducing costs.

[0145] See FIG. 19 As shown, in one embodiment, the head unit 100 is provided with a locking shaft 120, which has a locking hole 121. The fixing part 610 is connected to the wall of the locking hole 121. In this way, the gathering member 600 and the head unit 100 are fixedly connected. Along the direction of gravity, the diameter of the locking hole 121 gradually increases, that is, the mating surface between the locking shaft 120 and the fixing part 610 is a conical surface, which makes the connection between the head unit 100 and the gathering member 600 better. Therefore, it can reduce the possibility of the gathering member 600 swaying during the rotation of the stirring tool 500.

[0146] Further, seeFIG. 19 As shown, the fixed part 610 is provided with a fixed flange 611 radially outward, the locking shaft 120 is connected with a locking nut 122, and the fixed flange 611 is threadedly connected with the locking nut 122. By threadedly locking the locking nut 122, the gathering part 600 and the locking hole 121 of the head unit 100 are further pressed, and the possibility of displacement and deviation of the gathering part 600 relative to the head unit 100 is reduced. Further, the locking nut 122 and the locking shaft 120 are provided with a silica gel pad 123, and the locking nut 122 is prevented from loosening by the silica gel pad 123.

[0147] Referring to FIGS. 18-20 As shown, in one embodiment, the stirring tool 500 includes a whisk 510, and the intercepting part 620 is provided with an intercepting groove 621 on the side facing the whisk 510. Since the edge of the scraper 601 is close to the inner bottom wall and the inner side wall of the stirring bowl 700, the liquid food material is intercepted into the intercepting groove 621 of the scraper 601 and accumulated, and the liquid surface of the liquid food material rises in the intercepting groove 621 of the scraper 601. At this time, the steel wires of the whisk 510 can fully contact the liquid food material, improving the whipping effect and increasing the success rate of whipping. The projection of the groove wall of the intercepting groove 621 on the horizontal plane is in the shape of a circular arc, and the center of the circular arc is collinear with the axis of the whisk 510. Since the trajectory of the whisk 510 when rotating is a circle, the center of the scraper 601 is coaxial with the whisk 510, so that the food material accumulated in the scraper 601 can better contact the whisk 510, mix more fully, and have a better whipping effect.

[0148] Further, referring to FIG. 19 As shown, the side edge and the bottom edge of the scraper 601 are covered with scraping soft rubber 622, which is in the shape of a spatula, so as to better gather liquid food materials such as egg liquid together and deliver them to the working area where the whisk 510 is located; at the same time, when the scraper 601 is operated, a comfortable scraping deformation feeling can be created for the user.

[0149] Referring to FIG. 3 , FIG. 5 and FIG. 7As shown, in one of the embodiments, the base unit 200 is provided with a first main shaft 241, and the head unit 100 is rotationally connected to the first main shaft 241. Specifically, the base unit 200 and the head unit 100 are both provided with a main shaft connecting hole 2411 for connecting the first main shaft 241, and the rotational connection between the head unit 100 and the base unit 200 is achieved through the first main shaft 241. Among them, the first main shaft 241 is sleeved with a main shaft elastic element 242, and one end of the main shaft elastic element 242 abuts against the head unit 100. When the head unit 100 is in the closed state, the main shaft elastic element 242 is in the deformed state, so when the head unit 100 is opened, the elastic force of the main shaft elastic element 242 also plays a role in driving the head unit 100 to move upward, assisting the user to open the head unit 100.

[0150] Referring to FIG. 7 and FIG. 16 As shown, in one of the embodiments, the base unit 200 is provided with a closing hook 243 and an opening hook 244 extending towards the head unit 100; the closing hook 243 is configured with a closing slot 2431, and the opening hook 244 is configured with an opening slot 2441 located above the closing slot 2431. Correspondingly, the head unit 100 is provided with a first limiting shaft 132, and when the head unit 100 is in the open state, the first limiting shaft 132 is clamped in the opening slot 2441, and through the clamping cooperation of the opening hook 244 and the first limiting shaft, the head unit 100 can be kept in the open state; when the head unit 100 is in the closed state, the first limiting shaft 132 is clamped in the closing slot 2431, and through the clamping cooperation of the closing hook 243 and the first limiting shaft, the head unit 100 can be kept in the closed state.

[0151] Referring to FIGS. 3-6 As shown, in one of the embodiments, the head unit 100 is fixedly provided with a limiting block 130, and the limiting block 130 is configured with a first sliding groove 131 extending in the horizontal direction, as shown by the arrow X in the figure, and the first limiting shaft 132 can slide in the first sliding groove 131. By setting the limiting block 130 and the first sliding groove 131, the movement track of the first limiting shaft 132 is constrained, so that the first limiting shaft 132 can be clamped with the closing slot 2431 or the opening slot 2441, and at the same time, it can also be withdrawn from the closing slot 2431 and the opening slot 2441, thereby ensuring that the body unit can be stably switched between the open state and the closed state. Further, the first limiting shaft 132 is sleeved with a damping ring 1321 for preventing the first limiting shaft 132 from colliding with the head unit 100 to produce noise.

[0152] Referring to FIGS. 3-6As shown, in one of the embodiments, the chef machine further comprises a first connecting rod 140 having a fulcrum end and a lifting end 142; the fulcrum end is provided with a first fulcrum shaft 141, and the lifting end 142 is connected with the head unit 100; lifting the lifting end 142 can drive the first connecting rod 140 to rotate around the first fulcrum shaft 141, so as to switch the head unit 100 to the open state. See FIGS. 2-4 As shown, the head unit 100 is provided with an unlocking button 151, which is provided with an abutting rib 1511 protruding towards the lifting end 142; the abutting rib 1511 can abut against the first connecting rod 140 to trigger the first connecting rod 140 to deflect around the first fulcrum shaft 141. The unlocking button 151 can be fixed on the head unit 100 by fasteners such as screws and the like. When the head unit 100 is in the closed state, the unlocking button 151 is lifted upwards, and under the action of the abutting rib 1511, the lifting end 142 of the first connecting rod 140 acts upwards and rotates around the first fulcrum shaft 141.

[0153] See FIG. 3 As shown, the head unit 100 is provided with a first pressing plate 152, which is pressed against the first fulcrum shaft 141, that is, the first fulcrum shaft 141 is fixed on the head unit 100 by the first pressing plate 152 to prevent the first fulcrum shaft 141 from being offset.

[0154] See FIGS. 3-7 As shown, in one of the embodiments, the first connecting rod 140 has a descending end 143, which is located on the two sides of the fulcrum end respectively; the descending end 143 is provided with an abutting inclined surface 1431 for abutting against the first limiting shaft 132; along the direction of gravity, the horizontal distance between the abutting inclined surface 1431 and the first fulcrum shaft 141 gradually increases, that is, the abutting inclined surface 1431 extends away from the first fulcrum shaft 141. In this way, when the lifting end 142 moves upwards, the descending end 143 of the first connecting rod 140 moves downwards, and the abutting inclined surface 1431 drives the first limiting shaft 132 to move in the first sliding groove 131 and move towards the first fulcrum shaft 141 of the first connecting rod 140, so that the first limiting shaft 132 exits from the closed clamping groove 2431. Further, the distance between the abutting rib 1511 of the unlocking button 151 and the first fulcrum shaft 141 is less than the distance between the descending end 143 and the first fulcrum shaft 141, so that the lifting operation of the head unit 100 is more labor-saving. Preferably, the distance between the abutting rib 1511 of the unlocking button 151 and the first fulcrum shaft 141 is 40 mm. The unlocking button 151 can make the descending end 143 strip the first limiting shaft 132 out of the closed clamping groove 2431 with the smallest movement distance, that is, the first limiting shaft 132 exits from the closed clamping groove 2431.

[0155] See FIG. 16As shown, the abutting inclined surface 1431 is covered with a sheath 1432, which can be a wear-resistant plastic part, and the sheath 1432 is fixedly connected to the descending end 143 of the first connecting rod 140. The first connecting rod 140 is a metal part, and the sheath 1432 is arranged to make the abutting inclined surface 1431 move more smoothly against the first limiting shaft 132 and not produce a metal collision sound.

[0156] Referring to FIGS. 3-6 As shown, in one embodiment, a limiting shaft elastic member 1322 arranged in a horizontal direction is arranged between the first limiting shaft 132 and the limiting block 130, and the abutting inclined surface 1431 drives the first limiting shaft 132 to move in the first sliding groove 131, thereby compressing the limiting shaft elastic member 1322. Thus, when the first connecting rod 140 is reset and the abutting limiting part is not in contact with the first limiting shaft 132, the first limiting shaft 132 is automatically reset under the action of the limiting shaft elastic member 1322.

[0157] Referring to FIG. 5 As shown, a connecting rod elastic member 144 arranged in a vertical direction is arranged between the first connecting rod 140 and the head unit 100, and when the head unit 100 is lifted, the descending end 143 moves downward and compresses the connecting rod elastic member 144. When the head unit 100 is slowly closed, the first connecting rod 140 is reset to a horizontal state under the action of the connecting rod elastic member 144, that is, the connecting rod elastic member 144 drives the descending end 143 to move upward, thereby achieving automatic reset of the first connecting rod 140.

[0158] Specifically, when the user presses the unlocking button 151, the unlocking button 151 pushes the first connecting rod 140 through the abutting rib 1511, and the first connecting rod 140 rotates around the first fulcrum shaft 141; the first limiting shaft 132 is pushed out of the clamping groove in the closed clasp through the abutting inclined surface 1431 of the first connecting rod 140, at which time the head unit 100 is not limited; under the action of the main shaft elastic member 242, the head unit 100 is opened by a certain angle around the first main shaft 241, prompting the user that the head unit 100 has been unlocked, at which time the user can continue to lift the head unit 100 until the first limiting shaft 132 enters the opening clamping groove 2441 of the opening clasp 244, at which time the locking position of the head unit 100 is reached when opening, and the head unit 100 reaches the maximum opening angle, which is 40 degrees in this embodiment. Understandably, after the first limiting shaft 132 is pushed out of the closed clasp 243 under the action of the abutting inclined surface 1431 of the first connecting rod 140, the unlocking button 151 does not need to be pressed all the time, but the head unit 100 still needs to be lifted by hand to move upward until the first limiting shaft 132 enters the opening clamping groove 2441 of the opening clasp 244.

[0159] Referring to FIG. 3As shown, in one of the embodiments, the head unit 100 is provided with a micro switch 161. The micro switch 161 can detect whether the head unit 100 is in an open state or a closed state. When the micro switch 161 is closed, it means that the head unit 100 is in the closed state, i.e., in the horizontal position, and the driving unit 300 can work.

[0160] As shown, FIG. 7 As shown, the base unit 200 is provided with a buffer 245 capable of abutting against the head unit 100. When the head unit 100 is closed in place, the buffer 245 will be pressed, and the head unit 100 will be buffered by the buffer 245, preventing the head unit 100 from colliding and damaging due to excessive speed and noise; at the same time, it can also prevent accidental collision when the head unit 100 is lifted.

[0161] As shown, FIG. 2 , FIG. 7 and FIG. 11 As shown, in one of the embodiments, the chef machine further comprises a decorative cover 800 rotatably connected to the base unit 200, and the decorative cover 800 is located between the head unit 100 and the base unit 200. Specifically, the base unit 200 and the decorative cover 800 are both provided with a decorative connecting part 247, and the decorative cover 800 and the base unit 200 are rotatably connected through the decorative connecting part 247. The decorative connecting part 247 can be a connecting hole, and the decorative cover 800 and the base unit 200 are rotatably connected through the shaft hole cooperation. In this way, when the head unit 100 is in the open state, the internal structure of the base unit 200 will not be exposed, ensuring the aesthetic effect of the chef machine, and reducing the risk of cutting the user by the exposed structure.

[0162] As shown, FIG. 11 As shown, in one of the embodiments, the head unit 100 is provided with a first pull hook 171 extending towards the decorative cover 800, and the decorative cover 800 is provided with a decorative clamping hook 810. When the head unit 100 is opened, the first pull hook 171 moves upward synchronously until the protrusion of the first pull hook 171 is lapped with the decorative clamping hook 810 of the decorative cover 800. With the continuous opening of the head unit 100, the decorative cover 800 can be driven to open relative to the base unit 200 through the clamping of the first pull hook 171 and the decorative clamping hook 810. FIG. 7 and FIG. 11 As shown, in one of the embodiments, the base unit 200 is provided with a decorative limiting column 246, and the decorative cover 800 is provided with a decorative limiting hook 820. When the decorative cover 800 is rotated to the maximum angle (correspondingly, the head unit 100 is also opened to the maximum angle), the decorative limiting column 246 will abut against the decorative limiting hook 820 to limit the rotation amplitude of the decorative cover 800, preventing the decorative cover 800 from continuing to move upward.

[0163] Any technical features in the above embodiments can be combined, and for the sake of brevity, not all possible combinations are described, however, any combination of the technical features is considered to be within the scope of the present disclosure. The above embodiments merely express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be noted that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
