This scheme improves the fixed connection structure between cutter and the knife rest among the prior art into swing joint structure for the cutter can be relative the knife rest and reciprocating motion between open position and the position of accomodating, and then makes the cutter possess two kinds of different states of open mode and state of accomodating. Specifically, when the cutter assembly or the stirring cup needs to be cleaned or the food processor does not need to work, the cutter moves from the open position to the storage position, and the cutter approaches to the cutter rest in the process and is switched to the storage state, so that the cutter assembly and the stirring cup are convenient to clean; when the food processor needs to work, the cutter moves from the storage position to the opening position and is switched to the opening state, and the cutter extends outwards to be greatly exposed out of the cutter frame, so that the normal realization of the food processing function of the food processor is ensured.

Of course, the cooperation between the tool and the tool holder can also take other forms. Such as: the connection structure still adopts fixed connection structure, and the cutter adopts flexible cutter, promptly: the tool is of a telescopic structure and comprises a fixing part and a telescopic part, the fixing part is fixed on the tool rest, the telescopic part is retracted into the fixing part in a storage state, and the telescopic part extends out of the fixing part in an opening state; wherein, the fixed part can be provided with a blade and fixed outside the tool rest; the fixing part can be fixed in the tool rest without a blade.

In the above technical solution, the movable connection structure is a rotary connection structure.

The movable connecting structure is a rotary connecting structure, so that the cutter can rotate in a reciprocating manner relative to the cutter frame, is not easy to separate from the cutter frame in the working process, and has high stability; meanwhile, the rotary motion of the cutter can be realized by reasonably utilizing the external space of the cutter frame, so that the size requirement on the cutter frame is reduced, and the structure of the cutter frame is simplified. Of course, the articulating mechanism is not limited to a pivoting linkage. Such as: the movable connecting structure can also be a sliding connecting structure, and the reciprocating motion is realized through modes such as radial sliding relative to the tool rest, or the movable connecting structure is a combination of the sliding connecting structure and a rotating connecting structure, so that the tool has the rotating motion and the sliding motion relative to the tool rest, and the reciprocating motion is realized. They are not listed here, and all the objects of the present invention can be achieved without departing from the design concept and spirit of the present invention, and therefore, they should be considered to be within the scope of the present invention.

In the above technical scheme, the rotation connecting structure comprises a rotating shaft and a shaft hole which are matched, wherein one of the rotating shaft and the shaft hole is arranged on the tool rest, the other one of the rotating shaft and the shaft hole is arranged on the tool, and the rotating shaft and the shaft hole are matched in an inserted manner.

Of course, the rotation connection structure can also be realized by a hinge, a rotary joint or other structures.

It can be understood that the rotating shaft and the cutter or the cutter rest can be of an integrated structure or a split structure, and are connected together through assembling, for example, mounting holes are formed in the cutter or the cutter rest, the rotating shaft and the mounting holes are matched in a plug-in mode to realize assembling matching with the cutter or the cutter rest, and further matched with the shaft hole in a plug-in mode to realize rotating connection of the cutter rest and the cutter. The cutter and the rotating shaft can be fixedly connected (namely, the cutter and the rotating shaft keep relatively static and rotate relative to the tool rest together to realize the storage or the opening of the cutter), and at the moment, the rotating shaft can specifically adopt a non-circular structure with a D-shaped or X-shaped cross section and the like to realize the relative static of the cutter and the rotating shaft, or can also adopt assembling modes such as welding, fastener connection and the like; the cutter and the rotating shaft can also be in rotating connection, namely the rotating shaft and the cutter frame are kept relatively static, and the cutter rotates relative to the rotating shaft to achieve storage or opening.

Alternatively, a portion of the tools may be attached to the tool holder at a location on the top surface of the tool holder, and other tools may be attached to the tool holder at a location between the top surface of the tool holder and the bottom surface of the tool holder, which is equivalent to a portion of the tools extending from the top surface of the tool holder and other tools extending from the side surfaces of the tool holder, which is beneficial to increasing the number of tools, increasing the longitudinal food processing range of the tool assembly, and thus increasing the operating efficiency.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

A cutter assembly and a food processor according to some embodiments of the present invention will be described with reference to fig. 1 to 40.

As shown in fig. 1, the embodiment of the first aspect of the present invention provides a cutter assembly 1 for a food processor, the food processor including a driving device, the cutter assembly 1 including: a tool holder 11 and a tool 12.

Specifically, the tool post is connected with a driving device, and the driving device drives the tool post 11 to rotate; the tool 12 is connected to the blade holder 11 by a connecting structure and is adapted to be switched between an open state and a stored state with respect to the blade holder 11, to be drawn toward the blade holder 11 during switching to the stored state (as shown in fig. 3, 7 and 8), and to be drawn toward the blade holder 11 during switching to the open state (as shown in fig. 4, 5 and 6).

The cutter assembly 1 provided by the embodiment of the first aspect of the invention changes the single state between the cutter 12 and the tool rest 11 in the prior art, so that the cutter 12 has two different states of an opening state and a storage state, and can work in the opening state, and can be cleaned in the storage state, because the cutter 12 is close to the tool rest 11 in the storage state, the condition that the cutter 12 always extends outwards and is greatly exposed out of the tool rest 11 in the prior art is avoided, the condition that the cutter 12 hurts a user is effectively prevented, the safety of a product is improved, meanwhile, the shielding of the cutter 12 on the cup bottom 31 can be reduced, and the cup bottom 31 of the stirring cup 3 can be conveniently cleaned without taking out the cutter assembly 1.

Specifically, the cutter assembly 1 includes a cutter holder 11 and a cutter 12, and the cutter holder can be connected to a driving device (such as a motor 4) of the food processor to rotate under the driving of the driving device, so as to drive the cutter 12 to rotate, cut and crush food, and the like. The cutter 12 is connected with the cutter frame 11, when the cutter assembly 1 or the stirring cup 3 needs to be cleaned or the food processor does not need to work, the cutter 12 is switched from an open state to a storage state, the cutter 12 is drawn close to the cutter frame 11 in the process as shown in fig. 3, 7 and 8, so that the cutter 12 does not extend outwards and is not exposed to the cutter frame 11 to a large extent, and at the moment, when a user takes out the cutter assembly 1 to clean or directly cleans the cutter assembly 1 and the stirring cup 3 in the stirring cup 3, the user is not easy to hurt the hand, the safety is improved, meanwhile, the shielding of the cutter on the cup bottom 31 can be greatly reduced, and the cup bottom 31 can be cleaned conveniently under the condition that the cutter assembly 1 is not taken out; when the food processor needs to work, the cutter 12 is switched from the storage state to the opening state, and in the process, the cutter 12 is unfolded relative to the cutter holder 11 as shown in fig. 4, 5 and 6, so that the cutter extends outwards to be greatly exposed out of the cutter holder 11, and as shown in fig. 3, the cutter rotates along with the cutter holder 11 under the driving of the cutter holder 11, so that the food can be effectively cut, crushed and the like, and the normal implementation of the food processing function of the food processor is ensured.

The specific structure of the cutter assembly 1 provided in the present application will be described in detail below with reference to some embodiments.

Example one

The connecting structure is a movable connecting structure, and the cutter 12 is connected with the cutter frame 11 through the movable connecting structure, is suitable for reciprocating motion between an opening position and a storage position relative to the cutter frame 11, is close to the cutter frame 11 in the process of moving from the opening position to the storage position so as to be switched to the storage state (shown in figures 3, 7 and 8), and is unfolded in the process of moving from the storage position to the opening position so as to be switched to the opening state (shown in figures 4, 5 and 6).

This scheme improves the fixed connection structure between cutter 12 and the knife rest 11 among the prior art into swing joint structure for cutter 12 can be relative knife rest 11 reciprocating motion between open position and storage position, and then makes cutter 12 possess two kinds of different states of open mode and storage state. Specifically, when the cutter assembly 1 or the stirring cup 3 needs to be cleaned or the food processor does not need to work, the cutter 12 is moved from the open position to the storage position, and in the process, the cutter 12 is close to the cutter rest 11 and then switched to the storage state, so that the cutter assembly 1 and the stirring cup 3 are conveniently cleaned; when the food processor needs to work, the cutter 12 moves from the storage position to the opening position, and then is switched to the opening state, and at the moment, the cutter 12 extends outwards to be greatly exposed out of the cutter rest 11, so that the normal realization of the food processing function of the food processor is ensured.

Specifically, the movable connection structure is a rotary connection structure.

The movable connecting structure is a rotary connecting structure, so that the cutter 12 can rotate in a reciprocating manner relative to the cutter frame 11, is not easy to separate from the cutter frame 11 in the working process, and has high stability; meanwhile, the external space of the tool rest 11 is conveniently and reasonably utilized to realize the rotary motion of the tool 12, so that the size requirement on the tool rest 11 is reduced, and the structure of the tool rest 11 is simplified.

The rotary connection structure includes a rotating shaft 1121 and a shaft hole 121 which are matched with each other, as shown in fig. 2, 5 and 7, one of the rotating shaft 1121 and the shaft hole 121 is disposed on the tool holder 11, the other is disposed on the tool 12, and the rotating shaft 1121 and the shaft hole 121 are inserted and matched with each other, as shown in fig. 5 and 7.

The rotating connection structure comprises a rotating shaft 1121 and a shaft hole 121 which are matched with each other, one of the rotating shaft 1121 and the shaft hole 121 is arranged on the tool rest 11, the other one of the rotating shaft 1121 and the shaft hole 121 is arranged on the tool 12, the rotating shaft 1121 and the shaft hole 121 are matched in a plug-in mode during assembly, the rotating shaft 1121 can rotate relative to the shaft hole 121, the rotating connection function of the tool rest 11 and the tool 12 can be achieved, the structure is simple, other parts do not need to be additionally arranged, the number of parts is favorably reduced, the assembly efficiency is improved, and the. Of course, the rotation connection structure can also be realized by a hinge, a rotary joint or other structures.

It is understood that the rotating shaft 1121 and the tool 12 or the tool holder 11 may be of an integral structure (as shown in fig. 2), or of a split structure, and are connected together by assembling, for example, mounting holes are provided on the tool 12 or the tool holder 11, the rotating shaft 1121 and the mounting holes are fitted to realize the assembling fit with the tool 12 or the tool holder 11, and further, are fitted to the shaft hole to realize the rotational connection between the tool holder 11 and the tool 12, as shown in fig. 15 and 19. The cutting tool 12 and the rotating shaft 1121 may be fixedly connected (i.e., the cutting tool 12 and the rotating shaft 1121 are kept relatively stationary and rotate together relative to the tool rest 11 to accommodate or open the cutting tool 12), and at this time, the rotating shaft 1121 may specifically adopt a non-circular structure with a D-shaped or X-shaped cross section to achieve the relative stationary of the cutting tool 12 and the rotating shaft 1121, or may also adopt an assembly manner such as welding or fastening; the cutting tool 12 and the rotating shaft 1121 may also be in a rotational connection, that is, the rotating shaft 1121 and the tool holder 11 are kept relatively stationary, and the cutting tool 12 rotates relative to the rotating shaft 1121 to achieve storage or opening.

Further, the extending direction of the rotating shaft 1121 is parallel to the axis of the rotating shaft 1121 of the tool holder 11, as shown in fig. 2.

The extending direction of the rotating shaft 1121 is parallel to the rotating shaft 1121 of the tool holder 11, and the rotating direction of the tool 12 relative to the tool holder 11 is parallel to the rotating shaft 1121 of the tool assembly 1 during the working process, so that the tool 12 is driven to be automatically opened or automatically retracted by the rotating inertia of the tool assembly 1 during the rotating process, thereby simplifying the movable connection structure and saving the production cost. Of course, the direction of extension of the rotation axis 1121 may be perpendicular to or inclined with respect to the rotation axis 1121 of the tool holder 11.

Here, the tool 12 is rotated by an angle α of greater than 0 ° and 270 ° or less with respect to the tool holder 11 when the storage state is switched to the open state, as shown in fig. 13.

Switch to the open mode by the state of accomodating, cutter 12 is greater than 0 and less than or equal to 270 for the rotatory angle of knife rest 11, it is too big to have avoided the 12 corners of cutter, be favorable to increasing the radial dimension that cutter 12 stretches out knife rest 11 on the one hand like this, and then enlarge the radial food processing scope of cutter 12, and then improve food processor's work efficiency, on the other hand is favorable to reducing the size of single cutter 12 along 11 circumferential direction of knife rest, be favorable to arranging more cutter 12 at same level like this, thereby increase the quantity of cutter 12, and then further improve food processor's work efficiency. Of course, the angle is not limited to the above range, and can be adjusted as needed in the actual production process. Further, the ratio of the maximum diameter D1 of the rotation locus of the tool 12 during rotation to the maximum diameter D2 of the rotation locus of the tool holder 11 during rotation is in the range of 1.5 to 3.5.

The maximum diameter of the rotational path of the tool 12 during rotation (i.e., twice the maximum distance between the outer contour of the tool 12 and the axis of rotation of the tool holder 11 in the open state, denoted as D1, as shown in fig. 13), which has a significant effect on the radial food processing range of the tool assembly 1; the maximum diameter of the rotational path of the tool holder 11 during rotation (i.e. twice the maximum distance between the outer contour of the side of the tool holder 11 and the axis of rotation of the tool holder 11, denoted D2, as shown in fig. 13) has a significant influence on the amount of space occupied by the tool assembly 1 in the mixing cup 3. Inject D1D 2 in 1.5 to 3.5's within range, both guaranteed that cutter unit 1 has great radial food processing scope to improve food processor's work efficiency, avoided cutter unit 1 to take up too much to stirring cup 3's space again, thereby improved stirring cup 3's space utilization.

Example two

The difference from the first embodiment is that: on the basis of the first embodiment, further, the connection structure is configured to: is suitable for automatically switching the cutter 12 to the opening state under the action of the rotation inertia moment, and the driving device can drive the cutter 12 to rotate.

The connecting structure is configured to enable the cutter 12 to be automatically thrown out under the action of the rotating inertia moment (or the centrifugal force of the cutter 12), and then switched to an opening state, so that the cutter 12 can be automatically opened without operating the cutter 12 when the food processor works, and then food is processed, thereby not only simplifying the movable connecting structure, but also reducing the operation difficulty of the food processor, being beneficial to simplifying an electric control system of the food processor, and further obviously reducing the production cost; and the driving device can drive the cutter to rotate, so that the cutter component 1 can synchronously rotate after the cutter 12 is opened, and the normal realization of the function of the food processor is ensured. Of course, other structures for manually or automatically opening the knife 12 may be additionally provided.

The cutter 12 can be thrown out automatically when rotating clockwise or counterclockwise, and can be designed as required during production.

It can be understood that, in the process of switching from the storage state to the open state, the rotation direction of the tool 12 relative to the tool holder 11 is opposite to the rotation direction of the tool holder 11 (as shown in fig. 6), so that when the tool holder 11 starts to rotate in a forward direction (e.g., rotate clockwise), the tool 12 can move backward relative to the tool holder 11 (e.g., rotate counterclockwise in a reverse direction relative to the tool holder 11) under the action of the rotational inertia moment, and thus, automatic throw-out opening is realized.

EXAMPLE III

The difference from the second embodiment is that: on the basis of the second embodiment, further, the connection structure is configured to: is adapted to automatically switch the cutter 12 to the storage state under the action of the rotational inertia moment.

A fan 5 is further disposed in the body 2 for dissipating heat from the motor 4.

In any of the above embodiments, the food processor is a wall breaking machine, a processor, a juice machine, or a blender.

The following describes in detail a specific structure of the food processor provided by the present application with reference to fig. 1 to 40 by taking a wall breaking machine as an example.

The knife of general broken wall machine or mixer is fixed to be exposed on the knife rest, easily bumps the hand when taking out the washing, also can lead to producing because the cutter can not contract simultaneously and shelter from the unable convenient bottom of cup that washs. In order to solve the problems of easy hand injury and difficult cleaning, the application designs a cutter and a cutter frame, when the cutter runs at a high speed, the cutter is opened by utilizing a centrifugal cutter generated by the cutter during rotation so as to carry out cutting or stirring work; when the machine does not work and stops rotating, the cutter is closed in the cutter rest under the action of a cutter resetting mechanism (or in a free state, namely no resetting mechanism, the cutter is reset and retracted by motion inertia generated from high speed to stop), so that the hand is not easy to be injured when the cutter rest is held for cleaning, the cleaning is convenient, and the like. The specific scheme is as follows;

fig. 10 shows an assembly drawing of the wall breaking machine, and fig. 1 shows an exploded view of the telescopic cutter assembly 1. Wherein, telescopic cutter subassembly 1 includes: a tool holder 11, a tool return mechanism, a two-form tool 12, etc., and is connected to a drive shaft 14 by a fastener (i.e., an internally threaded end cap 15).

Figures 3 and 7 show the telescopic cutter member 1 when the machine is not rotating. At this time, the retractable tool 12 is in the home position, and the tool 12 is secured in the tool holder 11 by the action of the tool return mechanism, with the cutting edge (i.e., cutting edge) inside.

Fig. 4 and 5 show the telescopic cutter member 1 in a state in which it is operated at high-speed rotation of the machine. When the cutter 12 is operated at a high speed, the cutter 12 is opened by centrifugal force generated when the cutter 12 rotates, so that effective crushing work is performed.

Further, with regard to the resetting of the tool 12, the following may be employed:

a: resetting is carried out through the pre-torsion force (torsion moment) of the torsion spring 13, as shown in fig. 1, 2 and 32, two ends of the torsion spring 13 are connected with the tool rest 11 and the tool 12 to form a resetting torsion force; or the cutter 12 is folded when the cutter stops by pre-pressure generated by an intermediate torsion spring 13 (shown in fig. 33) or a spring sheet.

B: through the inertia reset that moves when free state rotation stops, cutter 12 because the inertia that the shutdown stopped when high-speed rotation stops, cutter 12 draws in the knife rest 11, promptly: the torsion spring 13 is eliminated and the cutter 12 is retracted by the inertia of movement when the cutter is stopped, as shown in fig. 34.

C: the friction force between the cutter 12 and the cutter frame 11 or between the cutter 12 and the shaft is increased by adding the elastic piece, the centrifugal force overcomes the friction force to open the cutter 12 when the cutter rotates at a high speed, the inertia overcomes the friction force to reset when the rotation stops, and the friction force enables the cutter 12 to be folded and not easy to release when the rotation stops.

The specific design and cooperation of the tool 12 and the tool holder 11 may be as follows:

the cutters 12 may be uniformly distributed at 90 degrees, the cutters 12 may be designed in a single layer (as shown in fig. 1, 5, and 7), the cutters 12 may also be uniformly distributed at 180 degrees in the circumferential direction, and the cutters 12 may also be uniformly distributed at 120 degrees or in other equal distribution as shown in fig. 20, 21, 23, and 25.

The cutting tools 12 are designed in a single layer (as shown in fig. 1, 5 and 7), the cutting tools 12 can also be designed in multiple layers, and the upper and lower layout are overlapped, as shown in fig. 12 and 16, or can be staggered.

The rotating throwing-out direction of the knife can be expanded to be clockwise or anticlockwise; the blade edges may be curved (as shown in fig. 6 and 8) or straight (corresponding to the shape of the blade holder 11 which may be square or polygonal), as shown in fig. 13, 17, 23, 25, 26 and 27.

Fixing manner of the cutter 12: the blade and the cutter shaft can rotate relatively; alternatively, the blade and the arbor are fixed in two D positions and then rotate together relative to the tool rest 11.

The tool holder 11 can be divided into an upper part and a lower part, as shown in fig. 1, or only the lower tool holder 11 is needed, and the upper tool holder 11 is not needed, as shown in fig. 5 and 7, or divided into an upper part, a middle part and a lower part, as shown in fig. 12 and 16.

The tool holder 11 may be one piece (as in fig. 21) or an assembly (of multiple pieces securely joined together as in fig. 20), and the tool holder 11 may have a variety of shapes (e.g., oval, polygonal …, etc.) as projected from the top of the machine.

Alternatively, the upper tool holder 11 may be designed as a wave wheel head, as shown in fig. 20 and 28, the wave wheel head may be made eccentric (as shown in fig. 29), and the lower tool holder 11 may be designed with turbulence ribs to form a wave wheel, as shown in fig. 20 and 21. Like this, the top impeller can increase the vortex, prevents to pile up, and middle part cutter 12 can be used for whipping, smashing, broken wall etc. and the bottom impeller can increase the vortex, prevents to stick with paste the end.

Further, fig. 13 shows that the ratio of the rotation diameter D1 of the extended tool 12 to the rotation diameter D2 of the tool rest 11 is D1/D2 is 1.5-3.5; and shows the opening angle alpha of the knife 12, i.e. the knife 12 is rotatable around the axis of rotation in the range 0 deg. to 270 deg. from the retracted position.

Fig. 6, 13, 17, 20, 21, 24, 25, 27, 28, 30, 31, and 35 show the open state of the cutter 12, and fig. 8, 22, 23, 26, 32, 33, 34, and 36 show the storage state. Further, this scheme not only can be used to in the broken wall machine, also can be used to in the cooking mixer of class. The shape of the knife 12 can vary, and the number of knives can be many, but at least two.

Further, the manual solution (i.e. the manual opening and closing of the knife 12 as described in the tenth embodiment) can be further expanded as follows: the setting tool 12 is fixed to the twist spindle 7, as shown in fig. 37; the assembly fixture 8 is fixed to the twist shaft 7.

The principle is as follows: opening-pressing the torsion shaft 7 downwards by a tool (such as a straight screwdriver), compressing the compression spring 9 again, moving the positioning member 8 (and the cutter 12) downwards until the protruding bayonet (namely, the clamping protrusion 81) on the positioning member 8 is separated from the groove (namely, the clamping groove 1191) on the lower cutter frame 11, rotating the torsion shaft 7 (namely, the cutter 12 and the positioning member 8 are rotated together) to align the protruding bayonet on the positioning member 8 with the groove of the required opening angle on the lower cutter frame 11 (the opening angle is designed to be 90 degrees in the pattern example), and releasing the tool to allow the compression spring 9 to recover to close the cutter 12 in the opening state. The principle of retracting the tool 12 is essentially the same, but the direction of rotation is reversed.

The following embodiments are designed for the square blade holder 11:

the upper, middle and lower three parts form the knife rest 11 (the knife rest 11 can be made into a whole theoretically, but the knife rest 11 is split into three parts because of complex production and assembly process), because the knife rest 11 has a multilayer blade mounting structure, the blades in the height direction can be arranged in multiple layers up and down, the blades in each layer can also be arranged in multiple sheets (or multiple blades), and the blades are distributed and uniformly distributed in the circumferential direction.

In fig. 12 to 15: in this embodiment, the knives are arranged in 2 layers in the height direction, each layer being 1 set of blades (2 leaves, i.e. two knives 12, one leaf for each knife 12). In addition, the top can be provided with an additional group of blades (2 leaves) besides the turbulence ribs.

In fig. 16 to 19: in the present embodiment, the knives are arranged in 2 layers in the height direction, each layer being 1 set of blades (4 blades, i.e. two knives 12, two blades per knife 12). In addition, the top can be provided with an additional group of blades (2 leaves) besides the turbulence ribs.

Further, it can also be designed that: bottom two-bladed blades, middle four-bladed blades, with or without top two-bladed blades.

The multi-layer, multi-blade, circumferentially uniform, top 2-blade cutter can also be used with other cutter holder 11 shapes, such as circular, polygonal, oval, etc. shaped cutter holders 11.

In summary, the cutter assembly provided by the invention changes the single state between the cutter and the cutter rest in the prior art, so that the cutter has two different states of an opening state and a storage state, and can work in the opening state, and can be cleaned in the storage state.
