Description

Technical Field

[0001] The invention belongs to the technical field of kitchen appliances, and in particular relates to a stirring cooking utensil. Background Art

[0002] The cooking machine is a new generation of microcomputer-controlled intelligent cooking equipment. The equipment is convenient, simple to operate, and smokeless. The cooking machine can not only automatically put in ingredients, season, stir-fry, control temperature, clean, and serve, but also has the functions of stir-frying, frying, cooking, deep-frying, frying, braising, steaming, boiling, baking, stewing, and boiling, which easily realizes the automation and fun of the cooking process. However, existing cooking machine products often have the following defects:

[0003] 1. During high-speed stirring, the container cup shakes violently. Some containers are not fixed with locks, and the container cup is easy to separate from the main machine. Some containers are equipped with one or two locks, which cannot be balanced and fixed. The container cup shakes violently and vibrates greatly during operation.

[0004] 2. The cover opening protection structure is complex and unstable. There are photoelectric cover opening protection, but the photoelectric cover opening protection has the hidden danger of instability under poor light conditions. There are also electric locks that use current detection micro switches to lock the cup cover, but this method is too expensive;

[0005] 3. During high-speed stirring, the blade holder in the container cup will vibrate greatly, and the blade assembly will be displaced due to the vibration, which may cause the blade holder to fall out. If the blade holder is not tightened properly, it is more likely to fall out.

[0006] 4. There are problems such as the motor and the knife assembly in the container cup are not concentric, and there are generally problems of large noise and vibration, or the positioning ribs are damaged after falling, resulting in the motor and the knife assembly not being concentric, causing greater noise and vibration;

[0007] 5. If consumers accidentally pour water from a cup into the main unit or forget to install the knife holder and put the cup in before pouring water, it is easy to cause a large area of ​​the main unit to be flooded;

[0008] 6. When the food ingredients make eccentric movement in the container cup, the vibration and torque generated are very large, causing the foot pad to vibrate and move. The whole machine will continue to jump, which may cause the machine to move off the table and fall to the ground, causing a serious accident.

[0009] Therefore, based on these problems, a stirring cooking utensil is provided which ensures the accuracy of weighing, prevents overflow of the whole machine, and is safe, stable, and highly controllable by jointly applying a container cup fixing structure, a lid opening protection structure, a knife assembly fixing structure, and a weighing foot assembly.

The container cup assembly 4 and the motor 3 are linked to each other through a cover opening protection structure. The knife assembly in the container cup assembly 4 and the motor 3 are linked to each other through a knife assembly fixing structure. A weighing foot assembly 5 is suspended on the mounting position.

[0121] Working principle: In this technical solution, the container cup component 4 and the main body shell adopt a split structure. A main body shell can be equipped with multiple container cup components 4 with different functions. When assembling, the container cup component 4 is inserted into the main body cover 1 and locked with the main body shell through the container cup fixing structure. When it is necessary to take out the container cup component 4, it can also be unlocked from the main body shell through the container cup fixing structure. The operation is convenient, so that the main body shell can hold the container cup component 4 well, and there is no need to worry about the container cup component 4 falling out or shaking, which greatly improves the user experience. When the container cup component 4 is assembled, the container cup component 4 and the motor 3 are connected through the cover opening protection structure. The two components are interconnected to realize the start and stop control of the motor 3. The structure is simple, reliable, practical, safe, stable, highly controllable, and low-cost, and is suitable for market promotion in the field of kitchen appliances. The knife assembly in the container cup assembly 4 and the motor 3 are interconnected through the knife assembly fixing structure. During high-speed stirring, the noise and vibration of the whole machine are greatly reduced, providing consumers with a better user experience. A weighing foot assembly 5 is suspended on the installation position. On the one hand, even if the main body shell is fully loaded with food on a tilted table, the weighing foot assembly 5 cannot touch the suction cup foot through-hole, thereby ensuring the accuracy of weighing. On the other hand, multiple drainage gaps are provided for the main body shell to prevent water from overflowing the whole machine.

[0122] Furthermore, in the present embodiment, it can also be considered that the container cup assembly 4 includes a container cup 6 and a cup seat 7 connected as one body, a knife assembly 8 assembled in the container cup 6, a container cover 9 snapped on the container cup 6, and a handle shell 10 fixed to one side of the container cup 6, wherein the handle shell 10 includes a handle seat 1001 and a handle cover 1002 assembled on the handle seat 1001, and a hollow working groove is provided in the handle seat 1001 along its length direction, so as to give the handle shell new functionality, and it can be used as an ordinary handle, which is practical, simple, beautiful and low in cost, and can also be used as a linkage structure between the container cover 9 and the motor 3. Only after it is detected that the container cover 9 is screwed on the container cup 6, the motor 3 is allowed to start working, which is safe, reliable, and multi-purpose, and suitable for market promotion.

[0123] Furthermore, in this embodiment, it can also be considered that Figure 6 As shown, at least two locking cover buckles 901 are spaced apart on the container cover 9, and the locking cover buckles 901 are open in the rotation direction of the container cover. The outer side of the cup edge of the container cup 6 is also protruded to form locking cover protrusions 601 which can be screwed into the locking cover buckles 901 one by one. The container cover 9 can be screwed onto the container cup 6 through the locking cover buckles 901 and the locking cover protrusions 601.

[0124] Furthermore, in this embodiment, it can also be considered that Figure 7-8As shown, the host upper cover 1 includes an upper cover side wall 101 with a cylindrical structure, an upper cover bottom wall 102 enclosed at the lower part of the upper cover side wall 101, and a circle of upper cover outer edge 103 formed at the upper edge of the upper cover side wall 101 and extending outward. A clearance groove 104 for avoiding the lower end of the handle shell 10 is opened on one side of the upper cover side wall 101 and the upper cover outer edge 103. A container cup installation space is formed above the upper cover bottom wall, and an electrical appliance installation space is formed below. During assembly, the cup holder 7 is inserted into the host upper cover 1 along with the container cup 6, and the handle shell 10 is inserted in alignment with the clearance groove 104. It should be noted that the clearance groove 104 is opened on one side of the host upper cover 1 to avoid the lower end of the handle shell 10, and can also play a positioning role, so that the container cup assembly 4 can only be inserted into the host upper cover 1 in one direction.

[0125] Embodiment 2:

[0126] Embodiment 2 of the present invention is further improved on the basis of embodiment 1 so as to give full play to the technical advantages of the present invention, which is described below by way of example.

[0127] For example: Figure 9-12 As shown, the container cup fixing structure includes a locking component 11, a locking opening 12, a rotating ring 13, a fixing hole 16 and a tension spring 17;

[0128] Wherein: the number of the locking parts 11 is at least three and they are evenly distributed on the periphery of the upper cover side wall 101, and they include a locking bracket 1101 and a locking buckle that can extend / retract on the locking bracket 1101, the locking bracket 1101 is fixed on the outer edge 103 of the upper cover on the periphery of the upper cover side wall 101, the plane where the locking bracket 1101 is located is tangent to the outer edge of the upper cover, the central axis of the locking bracket 1101 is perpendicular to the central axis of the locking buckle, and a sliding hole is opened through it for the locking buckle to slide and adapt;

[0129] Among them: the number of the lock openings 12 is the same as the lock parts 11, which are evenly opened on the upper cover side wall 101 and correspond to each other for the lock to extend / retract;

[0130] Among them: a rotating ring 13, which is rotatably mounted on the outer periphery of the upper cover side wall 101, and is provided with a release lever 14 for driving the rotating ring 13 to rotate, and a rotating ring boss 15 for driving the lock buckle to retract;

[0131] Among them: the fixing holes 16, the number of which is the same as the locking part 11, are evenly opened on the side wall of the cup holder 7 and are corresponding to each other for the locking buckle to be inserted, and the fixing holes 16 are used for the end of the locking buckle to extend / exit and realize the locking / unlocking of the container cup assembly 4;

[0132] Among them: one end of the tension spring 17 is fixed on the rotating ring 13, and the other end is fixed on the outer edge 103 of the upper cover.

[0133] The locking principle of the lock component 11: the number of the lock components 11 is at least three, which are evenly distributed on the periphery of the main unit upper cover 1, and the lock bracket 1101 is fixed on the main unit upper cover 1. The lock can extend / retract on the lock bracket 1101. In the free state, the first return spring on the lock component 11 pushes the lock outward, and the end of the lock extends out of the lock opening 12. When the container cup assembly 4 is placed in the main unit shell, the bottom edge of the container cup assembly 4 presses down the head slope of the lock, and the lock retracts into the lock opening 12. When the container cup assembly 4 is placed at the bottom, under the action of the first return spring, the lock continues to be pushed outward and extends into the fixing hole 16 of the container cup assembly 4, thereby locking the container cup assembly 4, so that the main unit shell can stabilize the container cup assembly 4 well. The container cup assembly 4 can be fully locked by at least three lock components 11, and there is no need to worry about the container cup assembly 4 falling out or shaking, which greatly improves the user experience.

[0134] The unlocking principle of the lock component 11 is as follows: because the release lever 14 is locked on the rotating ring 13, when the release lever 14 is pushed clockwise, the rotating ring boss 15 of the rotating ring 13 squeezes and stretches the lock boss of the lock component 11, so that the lock is retracted into the lock opening 12. When the lock is out of the fixing hole of the container cup assembly 4, the container cup assembly 4 can be lifted up, and the container cup assembly 4 can be easily unlocked by the release lever 14, which is easy to operate.

[0135] Furthermore, in this embodiment, it can also be considered that Fig.11 As shown, the lock includes a lock sliding portion 1102, a lock head 1103, a lock boss 1104 and a first return spring 1105;

[0136] Among them: the lock sliding part 1102 is perpendicular to the lock bracket 1101 and can slide freely on the lock bracket 1101, the straight line where the axis is located is parallel to the radial direction of the upper cover side wall 101, and a limit block is provided at one end away from the upper cover side wall;

[0137] Among them: the lock head 1103, which is installed at one end of the lock sliding part 1102 close to the side wall of the upper cover, is a right-angled trapezoidal block structure; a limiting ring is provided between the lock head 1103 and the lock sliding part 1102, and the size of the limiting ring is much larger than the size of the lock opening 12, which is used to prevent the lock head 1103 from extending too much, and the thickness of the lock head 1103 away from the lock sliding part 1102 is less than the thickness of the side close to the lock sliding part 1102, and its upper surface is an inclined surface, and the lower surface is a horizontal surface.

[0138] Among them: the lock boss 1104 is installed on the lock sliding part 1102, which is a right-angle trapezoidal block structure;

[0139] Among them: the first return spring 1105 is sleeved on the lock sliding part 1102 between the lock bracket 1101 and the lock head 1103.

[0140] The locking principle of the lock: there are at least three lock brackets 1101, which are evenly distributed on the periphery of the main cover. The lock can extend / retract on the lock bracket 1101. In the free state, the first return spring 1105 is in a free extension state to push the lock head 1103 outward, and the lock head 1103 extends out of the lock opening 12. When the container cup assembly 4 is placed in the main body shell, the bottom edge of the container cup assembly 4 presses down the inclined surface of the lock head 1103, and the lock head 1103 is compressed and retracted into the lock opening 12. At this time, the first return spring 1105 is in a compressed state. When the container cup assembly 4 is placed at the bottom, under the action of the elastic force of the first return spring 1105, the lock head 1103 continues to move outward and extends into the fixing hole of the container cup assembly 4, thereby realizing the locking of the container cup assembly 4.

[0141] Unlocking principle of the lock: because the release lever 14 is locked on the rotating ring 13, the release lever 14 is pushed clockwise, and the rotating ring boss 15 of the rotating ring 13 squeezes and stretches the locking boss 1104 of the locking component 11, and the locking sliding part 1102 moves in the sliding hole accordingly, and then the locking head 1103 shrinks into the locking opening 12. When the locking head 1103 exits the fixing hole of the container cup assembly 4, the container cup assembly 4 can be lifted up, and the container cup assembly 4 can be easily unlocked by the release lever 14, which is easy to operate.

[0142] Furthermore, in this embodiment, it can also be considered that Figure 7-12 The rotating ring 13 is an annular structure, the upper part of which is connected to the release lever 14 movably inserted in the arc-shaped through-groove 18 of the outer edge 103 of the upper cover, and the lower part of which is connected to the rotating ring boss 15. The number of the rotating ring bosses 15 is the same as the number of the locking components 11. The rotating ring bosses 15 are right-angled trapezoidal block structures, and the inclined surface of the rotating ring boss 15 is opposite to the inclined surface of the locking boss 1104. The rotating ring 13 is provided with at least three arc-shaped sliding grooves 19 opened along its circumference at equal intervals, and a ring body guide wheel 20 is engaged in the arc-shaped sliding groove 19. The ring body guide wheel 20 is slidably connected to the arc-shaped sliding groove 19 and the ring body guide wheel 20 is fixedly connected to the outer edge 103 of the upper cover. The rotating ring 13 is fixed to the main body cover 1 by at least three ring guide wheels 20, and the ring guide wheels 20 are slidably connected with the arcuate slide groove 19. When the release lever 14 is pushed clockwise, the arcuate slide groove 19 slides along the ring guide wheel 20. At this time, the tension spring 17 is in an elongated state. When the force acting on the release lever 14 disappears, the tension spring 17 tightens the rotating ring 13 in a counterclockwise direction, and the locking component is reset, so that the container cup fixing structure is suitable for repeated operations.

[0143] Embodiment 3:

[0144] Embodiment 3 of the present invention is further improved on the basis of Embodiment 1 / 2 so as to give full play to the technical advantages of the present invention, which is described below by way of example.

[0145] For example: Figure 13-15 As shown in FIG. 28 , the cover opening protection structure includes a handle safety link 21, a second return spring 22, a hook buckle 23 and a micro switch 24;

[0146] Among them: the handle safety link 21, which can move up and down in the hollow working groove of the handle seat, includes a link body 2101, a driving inclined surface 2102 and a driving rod 2103 respectively arranged on the upper and lower parts of the link body 2101;

[0147] Wherein: the second return spring 22 is sleeved on the driving rod 2103 and located between the connecting rod body 2101 and the handle seat 1001;

[0148] Among them: a hook buckle 23, which is fixed to the lower end of the container cover 9, and a buckle inclined surface is formed at the lower part thereof for driving the handle safety link 21 to move up and down;

[0149] Among them: the micro switch 24 is assembled in the main body shell, and the driving rod 2103 drives the spring of the micro switch 24 to press down / pop up through the main body safety connecting rod 25. The micro switch 24 can be but not limited to a micro switch of model 159030, and can also be implemented by photoelectric or other switches.

[0150] Furthermore, in this embodiment, it can also be considered that Figure 6 , 15 As shown, the hook buckle 23 includes an integrally connected support portion and a trigger portion, the buckle slope is formed at the lower part of the trigger portion, one side of the buckle slope is also concavely provided with a positioning groove, and one side of the driving slope is also convexly provided with a positioning rib that matches the positioning groove. When the buckle slope squeezes the driving slope 2102, the driving slope 2102 moves downward until the positioning rib is just stuck in the positioning groove. The positioning rib and the positioning groove restrict each other, play a positioning role, and the container cover will not easily loosen when tightened.

[0151] Furthermore, in this embodiment, it can be considered that the upper part of the handle seat 1001 is provided with an opening for the trigger part to enter, the lower part is provided with a first through hole for the driving rod 2103 to freely extend, and the connecting rod body 2101 is provided with at least two slide grooves along its length direction, and a connecting rod guide wheel is engaged in the slide groove, and the connecting rod guide wheel is slidably connected to the slide groove and the connecting rod guide wheel is fixedly connected to the container cup 6 / handle seat 1001. When the connecting rod body 2101 moves up and down, the slide groove can move up and down on the connecting rod guide wheel accordingly, playing a guiding role, and preventing the connecting rod body 2101 from deflecting during the movement process.

[0152] The working principle of the cover opening protection structure is as follows: when the container cover 9 is screwed into place, the hook buckle 23's buckle slope squeezes the driving slope 2102 to press the handle safety link 21 as a whole downward, and at the same time, the handle safety link 21 presses the host safety link 25 downward, and at the same time, the host safety link 25 presses the spring of the micro switch 24 downward to the bottom, so that the micro switch 24 is triggered to form a closed circuit. The micro switch is located on the control circuit of the motor (such as Fig.28 As shown), at this time, the signal current for controlling the start of the motor is turned on, and the motor starts working, that is, the motor is allowed to start working only after it is detected that the container cover 9 is tightened on the container cup 6, which meets the safety requirements and greatly reduces the probability of mechanical hazards; on the contrary, when the container cover 9 is reversely rotated and loosened, the handle safety link 21 is reset when the buckle slope of the hook buckle 23 is withdrawn, and at the same time, the host safety link 25 is also reset, and the spring of the micro switch 24 is restored to a free state, and the micro switch 24 forms an open circuit, at this time The signal current for controlling the start of the motor is disconnected, and the motor stops working.

[0153] Furthermore, in this embodiment, it can be considered that a micro switch bracket 26 is also installed in the mainframe housing, and the mainframe safety link 25 and the micro switch 24 are respectively located in the micro switch bracket 26. Fig.15 As shown, the micro switch bracket 26 is used to locate / fix the positions of the host safety link 25 and the micro switch 24 , and the spring of the micro switch 24 is arranged facing the trigger slope of the host safety link 25 .

[0154] Embodiment 4:

[0155] Embodiment 4 of the present invention is further improved on the basis of embodiment 3 so as to give full play to the technical advantages of the present invention, which is described below by way of example.

[0157] Among them: the safety link body 2501, the side of which facing the micro switch 24 is formed with a trigger slope 2502 for triggering the opening / closing of the micro switch 24, the upper and lower parts of the host safety link 25 are respectively vertically connected with an upper trigger rod 2503 and a lower trigger rod 2504, and the escape hole column for the upper trigger rod 2503 to pass upward is provided in the escape groove 104, and the upper trigger rod 2503 passes upward through the escape hole column and abuts against the driving rod 2103 up and down; the safety link body 2501 is used as a safety Full linkage structure, when the container cup assembly 4 is accurately assembled on the main body cover 1, the driving rod presses down the upper trigger rod 2503, and the safety link rod body 2501 moves down accordingly, and the trigger slope 2502 drives the spring of the micro switch 24 to press down to the bottom so that the trigger micro switch forms a closed circuit; conversely, when the container cup assembly 4 is removed, the safety link rod body 2501 is reset, the spring of the micro switch returns to a free state, and the micro switch forms an open circuit. The structure is simple, reliable, practical, safe, stable, and highly controllable.

[0158] Among them: the water receiving trough 2505 is formed by being recessed downward from the upper part of the safety link body 2501, and its bottom is semi-closed, and it is located below the avoidance hole column;

[0159] Among them: the drainage hole 2506 is arranged at the lower part of the safety link body 2501, and is connected with the water receiving tank 2505 through the overflow channel 2507. The water collected in the water receiving tank 2505 can flow out through the overflow channel 2507 and the drainage hole 2506 and fall into the drainage gap 52 and flow out of the main body shell to prevent water from entering the micro switch 24.

[0160] Furthermore, in this embodiment, it can also be considered that the drainage holes 2506 are at least a pair, which are relatively opened on both sides of the lower part of the overflow channel 2507, and the lower opening end of the water receiving trough 2505 corresponds to the overflow channel 2507 and the drainage holes 2506 in the upper and lower parts.

When the container cup assembly is removed, the host safety link 25 is reset under the action of the elastic force of the third reset spring, and the spring of the micro switch 24 returns to a free state.

[0162] Embodiment 5:

[0163] Embodiment 5 of the present invention is further improved on the basis of embodiments 1 / 2 / 3 / 4 so as to give full play to the technical advantages of the present invention, which is described below by way of example.

[0164] For example: Figure 17-20 As shown, the knife assembly fixing structure includes a knife assembly 8, an upper clutch 27, a lower clutch 28 and a knife assembly fixing lock 30;

[0165] Wherein: the knife assembly 8 comprises a knife seat 801 mounted on the bottom wall of the container cup, and at least two sets of knife sets 802 arranged alternately up and down;

[0166] Among them: the upper clutch 27 is coaxially arranged below the knife seat 801, and is a star-shaped columnar structure with an even number of sides;

[0167] Among them: the lower clutch 28 is coaxially arranged above the motor, and its upper surface is concave downward from the middle to form a star-shaped columnar groove for the upper clutch to be matched and inserted, and a hollow washer 29 is matched and clamped between the upper clutch and the star-shaped columnar groove;

[0168] Among them: the knife assembly fixing lock 30 is movably sleeved on the outside of the knife seat 801 and is locked with the knife seat 801 through a screw-on assembly, and at least two wrench ribs 3001 are evenly formed on its outer wall along the circumferential direction.

[0169] In this technical solution, if Figure 3 , 17 As shown in FIG. 20, after the knife holder 801 is installed on the bottom wall of the container cup, the knife assembly fixing lock 30 is inserted into the knife holder 801 from bottom to top and the knife assembly fixing lock 30 is rotated forward to Figure 3 For example, when the knife assembly fixing lock 2 rotates counterclockwise (forward rotation), it can be locked with the knife seat through the turn-lock assembly; the container cup assembly is assembled on the main cover 1, and the upper clutch 27 can be matched and inserted on the lower clutch 28 to realize the transmission connection between the knife group, the knife group shaft, the upper clutch, the lower clutch, and the motor.

[0170] Furthermore, in this embodiment, the upper clutch 27 and the star-shaped columnar groove are respectively six star-shaped columnar structures with six arc / tooth-shaped protrusions distributed along the circumferential direction, and the edges of the upper clutch 27 and the star-shaped columnar groove are arc transitions, and the transmission connection between the upper and lower clutches has a soft rubber buffer, which helps to improve the stability and concentricity of the assembly and helps to reduce the noise and vibration of the whole machine.

[0171] Furthermore, in this embodiment, it can be considered that the knife seat 801 includes a knife seat column, a knife seat platform of a truncated cone structure formed on the knife seat column, the knife group and the upper clutch are respectively installed on the upper and lower parts of the knife seat through the knife group shaft, the knife seat column is fixed on the bottom wall of the container cup 6, and a sealing ring 33 is installed between the knife seat and the bottom wall of the container cup to improve the sealing between the knife seat and the container cup. Preferably, the upper and lower surfaces of the sealing ring 33 are respectively convex and distributed with a plurality of circles of sealing concentric rings, and the knife seat between the bottom wall of the container cup 6 and the knife assembly fixing lock 30 is sleeved with a corrugated washer 31 and a pressing block 32. The pressing block 32 is used to press the corrugated washer 31 and limit the corrugated washer 31 from shaking around. When the knife assembly fixing lock 30 tightens the knife assembly, the pressing block 32 will be pressed against the corrugated washer 31 and the corrugated washer 31 will be deformed and have some elasticity, which can prevent the knife assembly from loosening and shockproof, and the assembly is also simple.

[0172] Furthermore, in the present embodiment, a cup seat hole 34 is provided in the middle of the cup seat 7 for the knife seat and the knife assembly fixing lock to pass through, and a pair of limit ribs 35 for limiting the forward rotation of the wrench rib 3001 are also provided on the periphery of the cup seat hole 34, and at least two anti-fool and anti-slip rib positions 36 for limiting the reverse rotation of the wrench rib 3001 are evenly fixed on the top wall of the upper cover bottom wall 102 along the circumferential direction. After the container cup assembly is assembled, the anti-fool and anti-slip rib positions 36 are located on the reverse rotation position side of the wrench rib for limiting its reverse rotation, and the limit ribs 35 on the periphery of the cup seat hole 34 are located on the forward rotation position side of the wrench rib for limiting its forward rotation, thereby further limiting the forward / reverse rotation of the knife assembly fixing lock 30 and the knife seat, and playing a two-way anti-slip effect.

[0173] In the present technical scheme, the container cup assembly is assembled on the main machine upper cover 1. In the present scheme, an anti-fool and anti-detachment rib position 36 is made on the top wall of the upper cover bottom wall 102. After the container cup assembly 4 is assembled in the main machine upper cover 1, the anti-fool and anti-detachment rib position 36 of the main machine upper cover 1 is on the side of the reverse rotation position of the wrench rib 3001. If the knife assembly fixing lock 30 is not rotated into place, when the knife assembly fixing lock 30 is loosened in the reverse direction, the anti-fool and anti-detachment rib position 36 will press against the wrench rib to prevent it from detaching. In addition, if the knife assembly fixing lock is not rotated into place, when the container cup assembly 4 is assembled in the main machine upper cover 1, the anti-fool and anti-detachment rib position 36 on the main machine upper cover 1 will press against the wrench rib, so that the container cup assembly 4 cannot be put to the bottom in the main machine upper cover 1. Only when the knife assembly fixing lock 30 is rotated into place can the container cup assembly 4 be put to the bottom, so as to prevent it from detaching. That is, only when the knife assembly fixing lock 30 and the knife seat are accurately locked and rotated into place, the container cup assembly 4 can be stably assembled on the main cover 1, and at this time, the anti-foolproof anti-slip rib position 36 and the wrench rib are just misaligned with each other. The purpose of setting the anti-foolproof anti-slip rib position 3 is: on the one hand, it has an anti-slip effect, and on the other hand, it has an anti-foolproof effect. The structure is simple, reliable, practical, safe, stable, and highly controllable, which greatly reduces the probability of mechanical danger.

[0180] Among them: the shockproof seat structure 40 is integrally formed on the inner surface of the mainframe upper cover, and includes a shockproof seat body for accommodating the arched shockproof pad body and a limiting hole for inserting the shockproof pad support rod.

[0181] In the present technical solution, when the shockproof pad structure 39 is assembled with the shockproof seat structure 40, the shockproof pad support rod 3902 is matched and inserted into the limiting hole, and the limiting step 3903 is stuck under the limiting hole, so that the shockproof pad structure 39 cannot be displaced in the vertical direction, and the arched shockproof pad body 3901 is matched and installed in the shockproof seat body, so that the shockproof pad structure cannot be displaced in the horizontal direction, and at this time, the upper part of the arched shockproof pad body 3901 is exposed above the shockproof seat body, and when the container cup assembly 4 is placed into the main cover 1, the bottom edge of the container cup assembly 4 is aligned with the bottom edge of the container cup assembly 4. The upper ends of the arched shockproof pad bodies 3901 are in contact and squeezed. Preferably, the arched shockproof pad body 3901 is made of soft rubber material.

[0182] Embodiment 7:

[0183] Example 7 of the present invention is further improved on the basis of Examples 1 / 2 / 3 / 4 / 5 / 6 so as to give full play to the technical advantages of the present invention, which is described below by way of example.

[0184] For example: the motor 3 is fixed in the main housing through a motor fixing structure, and the motor fixing structure includes an upper shockproof structure and a lower shockproof structure respectively installed on the upper and lower parts of the motor to prevent the motor from longitudinal displacement and vibration, and a peripheral shockproof structure evenly distributed on the periphery of the motor to prevent the motor from lateral displacement and vibration. The upper shockproof structure is located between the bottom wall 102 of the upper cover and the motor 3, which is a shockproof rubber sleeve 41, which includes a shockproof surface of a cylindrical structure, a circle of shockproof rings formed at the upper end of the shockproof surface and extending inward, and the lower shockproof structure is a shockproof gasket 42. The main base 2 is formed with a peripheral rib 43 for supporting and positioning the lower shockproof structure, and at least four to eight vertically arranged sleeve columns 44 are evenly spaced around the periphery of the peripheral rib 43. The peripheral shockproof structure includes a shockproof sleeve 45 that is sleeved on the sleeve column 44 in a one-to-one correspondence, and the outer wall of the shockproof sleeve 45 is protruded with a convex strip that fits tightly with the motor.

[0185] In this technical solution, the motor 3 is installed between the main engine cover 1 and the main engine base 2. On the one hand, by installing a circle of upper shockproof structure between the main engine cover 1 and the motor 3 to fix the upper half of the motor 3, the problem of the motor 3 and the main engine cover 1 not being concentric is solved, and then the noise is reduced. The upper shockproof structure can play a role in shock absorption, fixing and center positioning for the motor 3; on the other hand, a circle of lower shockproof structure is installed between the motor 3 and the main engine base 2 to support the motor to eliminate vibration. The upper shockproof structure and the lower shockproof structure arranged relatively up and down can not only prevent the longitudinal displacement and vibration of the motor, but also play a role in center positioning for the motor; at the same time, the motor 3 is evenly distributed with a peripheral shockproof structure, which is used to assist the concentricity positioning of the bottom of the motor and to assist in preventing the motor from impacting the main engine cover when falling, and can also effectively prevent the lateral displacement and vibration of the motor. This technical solution assembles the upper shockproof structure, the lower shockproof structure and the peripheral shockproof structure together, which can not only play a role in center positioning for the motor 3 and reduce noise, but also prevent the motor from lateral and longitudinal displacement and vibration.

[0186] It should be noted that the upper shockproof structure, the lower shockproof structure, and the peripheral shockproof structure can be made of but not limited to rubber materials, which can play a good role in shockproofing and noise reduction. When a fall occurs, the upper shockproof structure, the lower shockproof structure, and the peripheral shockproof structure can greatly reduce the impact of the motor on the main cover, base and surrounding structures, thereby increasing the service life of the entire machine.

[0187] Embodiment 8:

[0188] Example 8 of the present invention is further improved on the basis of Examples 1 / 2 / 3 / 4 / 5 / 6 / 7 so as to give full play to the technical advantages of the present invention, which is described below by way of example.

[0189] For example, the mainframe upper cover 1 is also provided with an overflow structure, and the overflow structure includes a mainframe upper cover drainage structure and an interference drainage structure;

[0190] Wherein: the drainage structure of the main unit upper cover comprises at least one side drainage hole 46 opened at the edge of the upper cover bottom wall 102, and a first water receiving component for receiving liquid in the side drainage hole 46;

[0191] The interference drainage structure includes a water receiving tray 47 for receiving liquid overflowing from the gap between the lower clutch 28 and the bottom wall 102 of the upper cover, and a second water receiving component for receiving liquid in the water receiving tray.

[0192] In the present technical solution, when the consumer accidentally pours water into the main unit cover 1 or forgets to install the knife holder and puts it into the container cup assembly before pouring water, it is easy to cause a large area of ​​the main unit housing to be flooded, and the accumulated water will overflow through the gap between the lower clutch and the main unit cover, causing water to enter the motor 3, resulting in motor 3 failure or safety problems. The overflow structure includes a main unit cover drainage structure and an interference drainage structure. The two drainage methods work together to effectively prevent the main unit from being flooded in a large area; wherein: the main unit cover drainage structure includes at least one side drainage hole 46 opened at the edge of the main unit cover 1, and a first water receiving component for receiving liquid in the side drainage hole 46, so that The water on the main unit cover 1 can be quickly drained through the side drainage hole 46 and the first water receiving component to prevent the main unit from being flooded in a large area; the interference drainage structure includes a water receiving tray 47 for receiving liquid overflowing from the gap between the lower clutch 28 and the bottom wall 102 of the upper cover, and a second water receiving component for receiving liquid in the water receiving tray 47. When there is too much water above the main unit cover 1, water will inevitably overflow from the gap between the lower clutch and the main unit cover to the motor, which may easily cause water to enter the motor. By arranging a water receiving tray 47 between the main unit cover 1 and the motor 3, water can be introduced into the area outside the motor through the second water receiving component to prevent water from entering the motor.

[0193] Furthermore, in this embodiment, it can be considered that a motor hole for partially inserting the lower clutch 28 is opened on the bottom wall 102 of the upper cover, at least one circle of water retaining ring 48 is formed downward on the outer side of the lower clutch 28, and a circle of water retaining wall 49 extends upward from the edge of the motor hole, and the upper end of the water retaining wall 49 extends into the water retaining ring 48. The flow path of the liquid flowing down from the gap between the lower clutch and the upper cover 1 of the main machine can be increased as much as possible, and then the amount of water overflow can be reduced as much as possible, reducing the drainage burden of the water receiving tray 47.

[0194] Furthermore, in this embodiment, it can be considered that the first water receiving component includes a base drain cylinder 50 vertically installed on the main unit base 2, a water receiving pipe 51 inserted into the upper end of the base drain cylinder 50, and the lower end of the side drain hole 46 is tightly connected to the open end of the water receiving pipe 51 through a handover structure. The base drain cylinder 50 penetrates the main unit base, and the water discharged through the side drain hole 46 is discharged out of the main unit base through the handover structure, the water receiving pipe 51, and the base drain cylinder 50 in sequence, so that the water above the main unit upper cover 1 can be quickly drained to prevent the main unit from being flooded in a large area.

[0195] It should be noted that the handover structure may include, but is not limited to, an inclined handover bottom surface formed by at least one bend along one side edge of the side drainage hole 46, and a connecting surface connected between the handover bottom surface and other edges of the drainage hole, and the handover bottom surface is inclined so that water above the main unit cover 1 can quickly flow into the water receiving pipe 51.

[0196] Furthermore, in the present embodiment, it can also be considered that the water receiving tray 47 is located between the upper cover base 102 and the motor 3, and the water receiving tray 47 includes a receiving tray surface 4701 and an outer tray wall 4702 extending upward along the edge of the receiving tray surface 4701, a water receiving notch 4703 is formed on one side of the outer tray wall 4702, and a water guiding lip 4704 is extended downward from the edge of the receiving tray surface below the water receiving notch 4703, and a tray hole through which the motor shaft of the power supply machine passes is formed on the receiving tray surface 4701, and a circle of inner tray wall 4705 is extended upward from the edge of the tray hole. Liquid overflowing from the gap between the lower clutch 28 and the main engine upper cover 1 falls onto the receiving plate 4701 under the action of gravity, flows down to the second water receiving component through the water receiving gap 4703, and is discharged through the second water receiving component to prevent water from entering the motor. The edge of the receiving plate 4701 below the water receiving gap 4703 has a water guide lip 4704 extending downward, which plays a guiding role.

[0197] Furthermore, in the present embodiment, it can also be considered that the second water receiving component includes a base drain cylinder 50 and a drain gap 52 vertically mounted on the main engine base 2, wherein the drain gap 52 is annular and cylindrical and is located between the weighing foot assembly 5 and the suction cup foot through hole 59, so that the water on the main engine base 2 can be drained through the drain gap 52, thereby preventing the liquid in the main engine base 2 from being unable to be drained and preventing the motor from being flooded, and adopting a variety of drainage methods to drain water and improve safety.

[0198] Embodiment 9:

[0199] Example 9 of the present invention is further improved on the basis of Examples 1 / 2 / 3 / 4 / 5 / 6 / 7 / 8 so as to give full play to the technical advantages of the present invention, which is described below by way of example.

[0200] For example: the weighing foot assembly 5 includes a cantilever beam assembly 53, an upper steel plate 54 and a weighing sensor bracket 55 respectively arranged on the upper and lower parts of the cantilever beam assembly 53, and a suction cup foot bracket 56 inserted under the weighing sensor bracket 55. A reset ring 57 for reducing lateral vibration and displacement of the circumference is provided between the weighing sensor bracket 55 and the suction cup foot bracket 56, and a suction cup foot 58 for reducing longitudinal vibration and lateral displacement is provided at the lower end of the suction cup foot bracket 56.

[0201] Furthermore, in this embodiment, the mounting position includes a suction cup foot through hole 59 which is opened on the main unit base 2 and through which the suction cup foot bracket 56 passes in suspension, and screw columns 60 which are respectively fixed to the periphery of the suction cup foot through hole 59, and the upper steel plate 54 is connected to the screw columns 60 by self-tapping screws, such as Figure 4 As shown, the integrated weighing foot assembly 5 is inserted into the suction cup foot through hole 59 , and the upper steel plate 54 and the screw column 60 are connected by self-tapping screws to achieve fixation between the upper steel plate 54 and the screw column 60 .

[0202] In this technical solution, if Figure 3-4 As shown in 25-27, the cantilever beam assembly 53 is fixed between the upper steel plate 54 and the weighing sensor bracket 55. The cantilever beam assembly 53 is used to sense weight, and the change of weight difference can be observed during cooking. The upper steel plate 54 and the weighing sensor bracket 55 stably clamp and fix the cantilever beam assembly 53 therebetween, and the suction cup foot bracket 56 is inserted under the weighing sensor bracket 55. Taking the cooking machine / dough kneading machine product as an example, in the cooking / dough kneading mode, when flour and water are mixed into dough, the vibration and torque generated by the eccentric movement of the dough in the cup are very large, causing the suction cup foot 58 to vibrate and displace, which is easy to cause serious accidents. For this reason, a reset ring 57 is installed between the weighing sensor bracket 55 and the suction cup foot bracket 56, wherein: the weighing sensor bracket The bracket 55 can make a certain degree of lateral movement around the suction cup foot bracket 56. When the reset ring 57 is squeezed and deformed by the weighing sensor bracket 55, it can absorb the lateral vibration and unload a part of the lateral torque. When the reset ring 57 is reset, it can also absorb the lateral vibration and lateral torque, thereby reducing the lateral vibration and displacement and preparing for the next squeezing and deformation. In addition, when the weighing foot assembly is assembled, the suction cup foot bracket 56 is suspended through the suction cup foot through hole 59. When the knife assembly in the cooking utensil makes an eccentric movement, the weighing foot assembly 5 will not touch the suction cup foot through hole 59 when it moves around. Even if the cooking machine is fully loaded with food on an inclined table, the weighing foot assembly 5 cannot touch the suction cup foot through hole 59, thereby ensuring the accuracy of weighing.

[0203] Furthermore, in this embodiment, it can also be considered that the cantilever beam assembly 53 includes a cantilever beam 5301, an outlet terminal 5302 extending outward from one side of the cantilever beam, and patches 5303 protruding from the upper and lower ends of the cantilever beam 5301, respectively.

[0204] It should be noted that the patch can firmly attach the strain gauge with weak current change to the elastic body (cantilever beam), so that it can be synchronized with the deformation of the elastic body, thereby achieving the effect of weak current change. The patch can be, but is not limited to, a weighing sensor of the LH-3505-001 model. The force-bearing surface of the cantilever beam 5301 is set as a small plane, and the sensing accuracy is higher. Since there are air-avoiding areas above and below the cantilever beam 5301, when the weighing beam cantilever beam 5301 is subjected to external force, the cantilever beam 5301 will deform. The weighing sensor deforms the elastic body of the weighing sensor component through the action of external force, thereby causing the strain gauge attached to the elastic body inside the weighing sensor to bend under force, resulting in a change in the resistance value of the strain gauge. The change in resistance value causes a slight change in weak current, which is displayed through the amplification of the external circuit board and the conversion of related software to show the weight. Among them, the food in the container cup can be regarded as an external force, and the weighing sensor converts the external force into an electrical signal.

[0205] It should also be noted that a weighing plate (not shown in the figure) is also provided on the main engine base, and the outlet ends 5302 of each cantilever beam 5301 are respectively connected to the weighing plate, and the weighing foot leads are electrically connected to the weighing sensor. The model of the weighing plate can be, but is not limited to, CMCZ 05. It should be further pointed out that the structure of the weighing plate is not the main technical innovation of this technical solution, so it is suitable for weighing plates available on the market. The structure of the weighing plate, as a prior art, does not need to be disclosed in this technical solution. Relevant knowledge about the internal structure of the weighing plate can be obtained by purchasing or querying relevant information on the Internet, and it does not require technical personnel in this field to make creative efforts.

[0206] Furthermore, in this embodiment, it can also be considered that the weighing sensor bracket 55 is a columnar structure, the upper part of which is concave to form a weighing avoidance groove 5501 for avoiding the patch position at the lower end of the cantilever beam assembly 53, and one side of the upper part also extends outward to form an assembly groove 5502 adapted to one end of the cantilever beam assembly, and the lower part protrudes downward to form a first hollow positioning column 5503. The weighing sensor bracket 55 is designed as an integrated structure, which is simple in structure, easy to assemble, and reduces multiple assembly tolerances.

[0207] Furthermore, in this embodiment, it can be considered that the reset ring 57 is an annular column structure, the reset ring 57 is sleeved on the outside of the first hollow positioning column 5503, and the reset ring 57 is provided with a plurality of shock-absorbing holes 5701 evenly arranged in an annular array, and the shock-absorbing holes 5701 are arranged obliquely toward the circumference of the reset ring 57. The purpose of setting the shock-absorbing holes 5701 on the reset ring 57 is that when the reset ring 57 is squeezed and deformed by the weighing sensor bracket, the shock-absorbing holes 5701 can absorb the lateral vibration and remove part of the lateral torsion, and when the reset ring 57 is reset, the shock-absorbing holes 5701 can also absorb the lateral vibration and lateral torsion, thereby reducing the lateral vibration and displacement and preparing for the next squeezing deformation.

[0208] Furthermore, in this embodiment, it can be considered that the suction cup foot 58 is stepped, including a rubber foot part and a suction cup part connected in sequence from top to bottom, and the lower part of the suction cup part is concave to form a truncated cone-shaped adsorption groove. When the cooking machine is placed on the desktop, the air in the suction cup foot 58 is squeezed out, causing the air pressure in the suction cup foot 58 to be less than the air pressure outside the suction cup foot, and the suction cup foot 58 is difficult to be pulled up, reducing the vibration and displacement of the cooking machine and increasing the stability of the whole machine. On the other hand, the suction cup foot 58 has a certain height and a certain elasticity, which not only helps to reduce the shock and fix the cooking machine, but also helps to dissipate the heat of the components above the main base.

[0209] Furthermore, in this embodiment, it can be considered that the suction cup foot bracket 56 is a columnar structure, and its upper part is upwardly protruding to form a second hollow positioning column 5601 that can be inserted into the first hollow positioning column 5503, and its upper edge is upwardly formed with a circle of positioning ring 5602 wrapped around the outside of the reset ring, and its lower part is concave to form a positioning groove for the suction cup foot 58 to match and insert. The reset ring 57 is sleeved on the outside of the first hollow positioning column 5503, and the suction cup foot bracket is inserted under the weighing sensor bracket, and the second hollow positioning column 5601 is inserted into the first hollow positioning column 5503. At this time, the reset ring 57 is accommodated in the space surrounded by the weighing sensor bracket, the positioning ring, and the suction cup foot bracket, and the rubber foot is inserted in the positioning groove.

[0210] Furthermore, in this embodiment, it can also be considered that the weighing foot assembly 5 further includes a positioning screw 61, which passes through the suction cup foot 58, the suction cup foot bracket 56, the second hollow positioning column 5601, the first hollow positioning column 5503 from bottom to top and is connected to the anti-drop nut 62 in the weighing avoidance groove 5501. The positioning screw and the anti-drop nut can fix the weighing sensor bracket, the suction cup foot bracket, the reset ring, and the suction cup foot into one.

[0211] Furthermore, in this embodiment, it can also be considered that Figure 4As shown, the suction cup foot bracket 56 is suspended through the suction cup foot through hole 59, and the movable gap between the suction cup foot bracket 56 and the suction cup foot through hole 59 is larger than the movable gap between the second hollow positioning column 5601 of the suction cup foot bracket and the first hollow positioning column 5503 of the weighing sensor bracket (the gap for the movement of the weighing foot assembly), so that the weighing foot assembly will not touch the suction cup foot through hole 59 when it moves around, and even if the cooking machine is fully loaded with food on a tilted table, the weighing foot assembly cannot touch the suction cup foot through hole 59, thereby ensuring the accuracy of weighing.

[0212] In summary, the present invention provides a stirring cooking utensil that ensures weighing accuracy, prevents overflow of the entire machine, and is safe, stable, and highly controllable by jointly applying a container cup fixing structure, a lid opening protection structure, a knife assembly fixing structure, and a weighing foot assembly.

[0213] The above embodiments describe the present invention in detail, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the present invention.
