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

[0002] The food processor includes a mixing bowl, a main unit, a bowl cover, and a mixing blade assembly. The bowl cover covers the mixing bowl. The main unit is placed on the bowl cover, and the main unit's motor is connected to the mixing blade assembly located in the mixing bowl. The motor rotates to drive the mixing blade assembly to grind the meat.

[0003] Technicians found that the above-mentioned food processor is prone to shaking and inconvenient to use. Utility Model Content

[0004] The present application aims to disclose a food processor that is not prone to shaking and is easy to use.

[0005] The present application discloses a food processor. The food processor includes a body, a mixing bowl, a bowl cover, a mixing blade assembly, and a head assembly. The body includes a base and a column; the column stands on the base, and the mixing bowl is fixed to the base during the operation of the food processor. The bowl cover covers the mixing bowl, and the mixing blade assembly is located inside the mixing bowl and is rotatably connected to the bottom of the mixing bowl. The head assembly is rotatably connected to the column and includes a motor; the head assembly flips in different directions in a vertical plane to switch between a locked position and a final raised position. In the locked position, the motor is located directly above the mixing blade assembly, and the motor shaft of the motor is coaxial with and abuts against the blade shaft of the mixing blade assembly.

[0006] As set up above, since the blade shaft of the mixing blade assembly is coaxial and abuts against the motor shaft of the motor, and the head assembly is locked in the locking position, the mixing blade assembly is effectively fixed in the axial direction and can only rotate in the mixing bowl. The mixing blade assembly is not easy to move, is not easy to cause the food processor to shake, and is easy to use.

[0007] In some embodiments, the base is provided with a suction cup, and the suction cup is used to adsorb the food processor to the table on which the food processor is placed.

[0008] As described above, since the mixing bowl is fixed to the base and adsorbed to the work surface by the suction cup, the mixing bowl is effectively fixed. Combined with the mixing blade assembly being effectively fixed in the axial direction, both hands can be freed. Consumers do not need to hold the food processor with both hands and press the switch with their fingers during use, making the food processor easy to use.

[0009] In some embodiments, the handpiece assembly includes a handpiece housing and a torsion spring assembly assembled to the handpiece housing, and the handpiece assembly is rotationally connected to the column via the torsion spring assembly. The torsion spring assembly includes a torsion spring. The handpiece housing is provided with an arcuate groove; the food processor includes a head-up switch assembly assembled to the column, and the head-up switch assembly includes a switch shaft; the switch shaft is inserted into the arcuate groove; in the locked position, the switch shaft is inserted into the head end of the arcuate groove and the torsion spring is deformed; in the final head-up position, the switch shaft is inserted into the tail end of the arcuate groove and the torsion spring returns to its natural state.

[0010] As set up as above, it is only necessary to press the head-lift switch assembly. Under the action of the torsion spring assembly, the movement of the head-lift assembly drives the movement of the arc groove, while the switch shaft is fixed. In this way, the switch shaft of the head-lift switch assembly changes from being located at the head end of the arc groove to being located at the tail end of the arc groove, thereby realizing the head-lifting of the machine head assembly; by pressing the machine head assembly, the switch shaft changes from being located at the tail end of the arc groove to being located at the head end of the arc groove and the torsion spring is compressed until the machine head assembly is in the locked position. It can be seen from the above process that the machine head assembly is easy to switch between the locking position and the final head-lifting position, which is more convenient for consumers to use.

[0011] In some embodiments, the arcuate slot includes an arcuate slot and latch holes at opposite ends of the slot. The latch holes are located at the leading and trailing ends of the arcuate slot, respectively. The diameter of the latch holes is greater than the width of the slot. The switch shaft includes a small shaft segment and a large shaft segment, the diameter of the small shaft segment being smaller than the diameter of the large shaft segment and smaller than the width of the slot. In the locked position, the large shaft segment is located within the latch hole at the leading end of the arcuate slot. In the final raised position, the large shaft segment is located within the latch hole at the trailing end of the arcuate slot.

[0012] As described above, the cooperation of the small and large shaft segments with the arcuate slot facilitates locking and raising the head assembly. Furthermore, in the locked position, the head assembly is locked, facilitating hands-free operation. In the final raising position, the large shaft segment is also locked within the retaining hole at the rear end of the arcuate slot. Only by pressing the raising switch assembly can the head assembly be switched from the final raising position to the locked position, thus ensuring safe use.

[0013] In some embodiments, the handpiece housing includes opposing mounting portions, and the torsion spring assembly includes a torsion spring shaft and a shaft fixing member. The torsion spring is positioned between the two mounting portions; the torsion spring shaft passes through the torsion spring, with both ends of the torsion spring shaft respectively passing through the two mounting portions; and the shaft fixing member is interposed with and fixed to the torsion spring shaft.

[0014] As described above, the torsion spring shaft passes through the torsion spring, and the shaft fixing member and the torsion spring shaft are inserted and fixed to each other, so that the torsion spring assembly is easy to fix and has fewer parts.

[0015] In some embodiments, the shaft fixing member and the torsion spring shaft respectively include a fixing column, and the food processor includes two locking members, each of which passes through the column and is locked with the corresponding fixing column.

[0016] As described above, since the shaft fixing member and the torsion spring shaft are respectively provided with fixing columns, the fasteners pass through the columns and are locked with the corresponding fixing columns. In this way, the fixation of the torsion spring assembly is achieved through a simple structure. During the process of flipping the machine head assembly, the torsion spring shaft will not rotate, ensuring smooth flipping of the machine head assembly.

[0017] In some embodiments, the head housing includes relative mounting portions, each of which is provided with the arc-shaped groove; the head-up switch assembly includes a head-up button and a head-up elastic member, and the two ends of the head-up elastic member are respectively abutted against the column and the head-up button; the switch shaft is spaced circumferentially from the head-up elastic member, and the switch shaft passes through the head-up elastic member and is provided with the arc-shaped groove of each of the mounting portions.

[0018] As described above, the switch shaft is spaced from the head-lift elastic member in the circumferential direction, and the switch shaft passes through the head-lift assembly and the arc groove. In this way, the switch shaft is not blocked during movement and moves smoothly.

[0019] In some embodiments, the head-up switch assembly includes a head-up button, and the switch shaft and the head-up button are directly inserted and fastened to each other.

[0020] As described above, since the switch shaft and the head-up button are directly inserted and fixed, the head-up switch assembly has fewer parts and is easy to assemble.

[0021] In some embodiments, the head assembly includes a head housing and a control switch for controlling the motor, wherein the motor is assembled in the head housing; the control switch is assembled on the top of the head housing, above the column.

[0022] As set up above, the control switch is located at the top of the machine head housing and above the column, which is convenient for arranging other components. For example, a control board can be set between the column and the motor.

[0023] In some embodiments, the mixing bowl and the base are fixed by a plurality of screwing structures, the plurality of screwing structures are evenly distributed around the circumference of the mixing bowl, and the screwing direction of each screwing structure is the same as the rotation direction of the blade shaft.

[0024] As set up above, the multiple tightening structures are evenly distributed around the mixing bowl, which can better lock the mixing bowl. In addition, the tightening direction of the tightening structure is the same as the rotation direction of the blade shaft. During the operation of the mixing blade assembly, the tightening structure will become tighter and tighter, making the mixing bowl and the base locked reliably, which is ultimately more conducive to freeing the consumer's hands.

[0039] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0040] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0041] See also Figures 1 to 3 、 Figure 8 、 Figure 10 and Figure 12 The present application discloses a food processor. The food processor can be used for at least mincing meat. The food processor comprises a body 1, a mixing bowl 2, a bowl cover 3, a mixing blade assembly 4, and a head assembly 5. The body 1 comprises a base 11 and a column 12. The column 12 is attached to the base 11. One function of the column 12 attached to the base 11 is to mount the head assembly 5. Therefore, its structure is not limited as long as it can achieve the function. The mixing bowl 2 is fixed to the base 11 during operation (e.g., mincing meat) of the food processor. In other words, there are two situations: 1) the mixing bowl 2 is fixed to the base 11 whether it is mincing meat or not in use; 2) the mixing bowl 2 is detachably assembled with the base 11, and is only attached to the base 11 during operation (e.g., mincing meat) and can be removed from the base 11 after use for cleaning, etc. The bowl cover 3 covers the mixing bowl 1. The mixing blade assembly 4 is located within the mixing bowl 2 and is rotatably connected to the bottom of the mixing bowl 2. There is no limit to how the connection is rotated, as long as it can cooperate with the motor to achieve the function of the food processor (such as mincing meat).

[0042] The head assembly 5 is rotatably connected to the column 12 and includes a motor 51. The head assembly 5 is flipped in different directions in the vertical plane to switch between the locking position and the final position of the head. Figure 1 and Figure 8 The head assembly 5 is shown in the locked position. Figure 2 and Figure 12 The final position of the head is shown. From this, it can be seen that the head assembly 5 can be switched from the locked position to the final position of the head by turning it clockwise. The head assembly 5 can be switched from the final position of the head to the locked position by turning it counterclockwise. Figure 8 In the locked position, the motor 51 is located directly above the mixing blade assembly 4, and the motor shaft 511 of the motor 51 is coaxial with and abuts against the blade shaft 41 of the mixing blade assembly 4. Of course, the abutment is achieved through a clutch, so that the motor 51 can drive the mixing blade assembly 4 to rotate in the mixing bowl 2.

[0043] As described above, since the blade shaft 41 of the mixing blade assembly 4 is coaxial with and abuts the motor shaft of the motor 51, and the head assembly 5 is locked in the locked position, the mixing blade assembly 4 is effectively fixed in the axial direction and can only rotate around the mixing bowl 2. As a result, the food processor is not prone to shaking during operation, making it easy to use. In addition, the motor 51 is located directly above the mixing blade assembly 4, and the motor shaft 511 is coaxial with and abuts the blade shaft 41. Because the motor 51 has a certain weight, it is also beneficial to position the center of gravity of the food processor more centrally, making it less likely to shake during operation and freeing up hands.

[0044] In some embodiments, the base 11 is provided with a suction cup 110, which is used to suck the food processor onto a countertop, such as a kitchen countertop, on which the food processor is placed. The number and / or structure of the suction cups 110 are not limited, as long as they can achieve the desired effect.

[0045] As described above, since the mixing bowl 2 is fixed to the base 11 and is adsorbed on the work surface by the suction cup 110, the mixing bowl 2 is effectively fixed. Combined with the mixing blade assembly 4 being effectively fixed in the axial direction, both hands can be freed. Consumers do not need to hold the food processor with both hands and press the switch with their fingers during use, making the food processor easy to use.

[0046] See also Figure 4 、 Figures 1 to 3 、 Figure 8 and Figure 12 The handpiece assembly 5 includes a handpiece housing 52 and a torsion spring assembly 53 assembled with the handpiece housing 52. In an embodiment of the present application, the handpiece housing 52 includes a lower housing 5201 and an upper cover 5202 covering the lower housing 5201. The handpiece assembly 5 is rotationally connected to the column 12 via the torsion spring assembly 53. The torsion spring assembly 53 includes a torsion spring 531.

[0047] The head housing 52 is provided with an arc groove 521. The food processor includes a head-up switch assembly 6 assembled on the column 12. The head-up switch assembly 6 includes a switch shaft 61. The switch shaft 61 is arranged to penetrate the arc groove 521. Figure 8 , in the locking position; the switch shaft 61 is inserted into the head end of the arc-shaped slot 521 and the torsion spring 531 of the torsion spring assembly 53 is deformed. Figure 12 At the final position of the head-up, the switch shaft 61 is inserted into the tail end of the arc-shaped slot 521 and the torsion spring 531 of the torsion spring assembly 53 returns to its natural state. Figure 8 and Figure 9 and Figure 12 and Figure 13 By comparison, the switching process of the head assembly 5 between the locked position and the final lifting position is as follows: the head assembly 5 is released by pressing the lifting switch assembly 6. As the torsion spring 531 of the torsion spring assembly 53 changes from a deformed state to a natural state, the head assembly 5 rotates clockwise and lifts. As the head assembly 5 is lifted, the switch shaft 61 is fixed. In this way, the switch shaft 61 changes from the head end of the arc groove 521 to the tail end of the arc groove 521, thereby achieving the lifting of the head assembly 5. When it is necessary to switch from the final lifting position to the locked position, the torsion spring 531 is deformed during the process of pressing down the head assembly 5. Accordingly, the switch shaft 61 changes from the tail end of the arc groove 521 to the head end of the arc groove 521 and is locked. The motor shaft 511 of the motor 51 abuts against the blade shaft 41 of the stirring blade assembly 4.

[0048] As set up as above, it is only necessary to press the head-raising switch assembly 6. Under the action of the torsion spring assembly 53, the switch shaft 61 of the head-raising switch assembly 6 switches from the head end of the arc groove 521 to the tail end of the arc groove 521, thereby realizing the head-raising of the head assembly 5; by pressing the head assembly 5, the switch shaft 61 moves from the tail end of the arc groove to the head end of the arc groove 521 and the torsion spring 531 is compressed until the head assembly 5 is in the locked position. It can be seen from the above process that the head assembly 5 is easy to switch between the locked position and the final head-raising position, which is more convenient for consumers to use.

[0049] See also Figure 3 、 Figure 4 、 Figure 8 and Figure 12 The arc-shaped slot 521 includes an arc-shaped slide slot 5211 and a locking hole 5212 located at opposite ends of the slide slot 5211. The two locking holes 5212 are respectively located at the head end and the tail end of the arc-shaped slot 521. The diameter of the locking hole 5212 is larger than the width of the slide slot 5211.

[0050] See also Figure 4 、 Figure 5 、 Figure 9 and Figure 13 The switch shaft 61 includes a small shaft section 611 and a large shaft section 612. The diameter of the small shaft section 611 is smaller than the diameter of the large shaft section 612 and smaller than the width of the slide groove 5211. In this more specific embodiment, the process of switching the head assembly 5 between the locked position and the final lifting position is as follows:

[0051] Will Figure 8 and Figure 9 In the locking position, the large shaft section 612 is located in the locking hole 5212 at the head end of the arc groove 521; see Figure 12 and Figure 13 In the final position of the head-up, the large shaft section 612 is located in the clamping hole 5212 at the tail end of the arc groove 521. More specifically, the head-up switch assembly 6 includes a head-up elastic member 63. Figure 8 and Figure 9 and Figure 12 and Figure 13 It can be seen from the comparison that when the head is to be raised, the head-raising switch assembly 5 is pressed, and the switch shaft 61 is in the Figure 9 The handpiece assembly 5 moves rightward in the middle, so that the small shaft segment 611 enters the retaining hole 5212 at the head end of the arc-shaped slot 521. Because the diameter of the small shaft segment 611 is smaller than the width of the slideway 5211, the torsion spring 531 acts to lift the handpiece assembly 5, and the slideway 5211 moves relative to the small shaft segment 611 until the small shaft segment 611 of the switch shaft 61 is located in the retaining hole 5212 at the tail end. When the handpiece assembly 5 reaches the final lifting position, the switch shaft 61 of the lifting switch assembly 6, under the action of the lifting elastic member 63, inserts the large shaft segment 612 into the retaining hole 5212 at the tail end. Thus, in the final lifting position, the handpiece assembly 5 cannot rotate. When the food processor needs to work (for example, mincing meat), first press the head-up switch assembly 6 to allow the small shaft segment 611 to enter the slide groove 5211. At this time, press the head-up assembly 5 downward, and the slide groove 521 moves relative to the switch shaft 61. As a result, the small shaft segment 611 changes from the locking hole 5212 at the tail end of the arc groove 521 to the locking hole 5212 at the head end of the arc groove 521. At the same time, the torsion spring 531 is deformed. At this time, under the action of the head-up elastic member 63, the switch shaft 61 inserts the large shaft segment 612 into the locking hole 5212 at the head end of the arc groove 521, and the head assembly 5 is in the locking position and is locked.

[0052] As described above, the cooperation between the small shaft segment 611 and the large shaft segment 612 and the arcuate slot 521 facilitates the locking and raising of the handpiece assembly 5. Furthermore, in the locked position, the handpiece assembly 5 is locked, which facilitates the freeing of hands. In the final raising position, the large shaft segment 512 is also locked within the latching hole 5212 at the rear end of the arcuate slot 521. Only by pressing the raising switch assembly 6 can the handpiece assembly 5 be switched from the final raising position to the locked position, thus ensuring safe use.

[0053] See also Figure 4 、 Figure 6 、 Figure 7 、 Figure 10 and Figure 11 , the head housing 52 includes relative mounting portions 522, and the torsion spring assembly 53 includes a torsion spring shaft 532 and an axis fixing member 533. The torsion spring 531 is located between the mounting portions 522. The torsion spring shaft 532 passes through the torsion spring 531, and the two ends of the torsion spring shaft 532 are respectively penetrated by the two mounting portions 522. The axis fixing member 533 is inserted into the torsion spring shaft 532 and fixed to each other. There is no limit to how they are fixed to each other, as long as the axis fixing member 533 and the torsion spring shaft 532 do not rotate relative to each other. For example, the torsion spring shaft 532 is hollow inside and includes a notch 5322, and the axis fixing member 533 includes a plug-in portion 5332, and the plug-in portion 5332 is inserted into the notch 5322 and fixed to each other.

[0054] As described above, the torsion spring shaft 532 passes through the torsion spring 531 , and the shaft fixing member 533 and the torsion spring shaft 532 are inserted and fixed to each other. The torsion spring assembly 53 is easy to fix and has fewer parts.

[0055] See also Figure 6 、 Figure 7 、 Figure 10 and Figure 11 The shaft fixing member 533 and the torsion spring shaft 532 each include a fixing post 534. More specifically, the torsion spring shaft 532 includes a torsion spring shaft body 5321, which is inserted through the mounting portion 522 and the torsion spring 531. The fixing post 534 is connected to the torsion spring shaft body 5321 to form an L shape. The shaft fixing member 533 includes a shaft fixing member body 5331 and the fixing post 534. The food processor includes two locking members, each of which passes through the column 12 and is locked with the corresponding fixing post 534. Figure 14 The column 12 is provided with a column hole 120 , and each locking member (such as a screw) passes through the column hole 120 and is locked with the corresponding fixing column 534 .

[0056] As described above, since the shaft fixing member 533 and the torsion spring shaft 532 are respectively provided with fixing columns 534, the fasteners pass through the column 12 and are locked with the corresponding fixing columns 534. In this way, the fixation of the torsion spring assembly 53 is achieved through a simple structure. During the process of flipping the head assembly 5, the torsion spring shaft 532 will not rotate, ensuring smooth flipping of the head assembly 5.

[0057] See also Figure 4 、 Figure 9 and Figure 13, the head housing 52 includes relative mounting portions 522, and each mounting portion 522 is provided with the arc-shaped groove 521. The head-up switch assembly 6 includes a head-up button 62 and a head-up elastic member 63. The two ends of the head-up elastic member 63 are respectively abutted against the column 12 (in this embodiment, the head-up switch assembly 6 also includes a switch bracket 64, and the switch bracket 64 is installed on the column 12. Thus, the head-up elastic member 63 abuts against the column 12 by abutting against the switch bracket 64. This can be understood as indirect abutment. In some embodiments, the head-up elastic member 63 may also directly abut against the column 12. The switch shaft 61 is spaced circumferentially from the head-up elastic member 63, and the switch shaft 61 passes through the head-up elastic member 63 and is also provided with two of the arc-shaped grooves 521.

[0058] As described above, the switch shaft 61 is spaced from the head-lift elastic member 63 in the circumferential direction, and the switch shaft 61 passes through the head-lift elastic member 63 and the arc groove 521 . In this way, the switch shaft 61 is not blocked during movement and moves smoothly.

[0059] See also Figure 4 The head-up switch assembly 6 includes a head-up button 62, and the switch shaft 61 and the head-up button 62 are directly inserted and fastened to each other. There are many ways to fix them, for example, by tight fitting at a flat position, etc.

[0060] As described above, since the switch shaft 61 and the head-up button 62 are directly inserted and fixed, the head-up switch assembly 6 has fewer parts and is easy to assemble.

[0061] See also Figure 1 、 Figure 2 、 Figure 8 and Figure 12 The head assembly 5 includes a head housing 52 and a control switch 54 for controlling the motor 51. The motor 51 is assembled in the head housing 52. The control switch 54 is assembled on the top of the head housing 52, above the column 12.

[0062] As described above, the control switch 54 is located at the top of the head housing 52 and above the column 12, which is convenient for arranging other components. For example, a control board can be set between the column 12 and the motor 51.

[0063] See also Figure 2 The mixing bowl 2 is secured to the base 11 via a plurality of screwing structures 111. In the embodiment of the present application, there are four screwing structures 111, but the number of screwing structures 111 is not limited. The plurality of screwing structures 111 are evenly distributed around the circumference of the mixing bowl 2, and the screwing direction of the screwing structures 111 is the same as the rotation direction of the blade shaft 41.

[0064] As set up above, the multiple tightening structures 111 are evenly distributed around the circumference of the mixing bowl 2, which can better lock the mixing bowl 2. In addition, the tightening direction of the tightening structure 111 is the same as the rotation direction of the blade shaft 41. During the operation of the mixing blade assembly 4, the tightening structure 111 will become tighter and tighter, so that the mixing bowl 2 and the base 11 are reliably locked, which is ultimately more conducive to freeing the consumer's hands.

[0065] See also Figure 4 and Figure 3 Each of the tightening structures 111 includes a slot 112 and a buckle portion 113, and the buckle portion 113 is provided on one of the mixing bowl 2 and the base 11 ( Figure 4 The card slot 112 is provided on the mixing bowl 2 and the other of the base 11 ( Figure 4 The structure of the slot 112 is not limited, and it can cooperate with the buckle portion 113 to achieve tightening. For example, the slot 112 is an arcuate groove along the circumference of the mixing bowl 2. The arcuate groove has a notch for the buckle portion 113 to enter.

[0066] As described above, the tightening structure 111 is formed by the slot 112 and the buckle portion 113 . The tightening structure 111 is simple, and thus the structure of the food processor is simple.
