Abstract
Description
Technical Field
[0001] The utility model relates to the field of kitchen appliances, in particular to a vegetable cutter. Background Art
[0002] In the traditional kitchen food preparation process, the operator uses a kitchen knife to cut vegetables manually, which requires the operator to have certain knife skills and techniques. It is difficult for unskilled people, and the processed vegetables are likely to be of different sizes, affecting the mood for eating. In addition, this method has the hidden danger of the kitchen knife easily cutting people, which poses a safety problem and has low cutting efficiency. In the current environment of pursuing high efficiency and fast-paced life, it is not conducive to improving user experience.
[0003] To address the aforementioned difficulties, safety issues, and inefficiencies associated with manual vegetable cutting, automatic vegetable cutters have emerged. These machines typically consist of a drive mechanism equipped with only the necessary cutting components, effectively limiting their use. Similarly, for meat cutting, automatic meat cutters typically consist of a drive mechanism equipped with only the necessary cutting components, effectively limiting their use. This requires users to purchase two separate machines for both vegetable and meat cutting, which is not only expensive but also takes up considerable space, leaving the kitchen with limited available space.
[0004] For example, in the prior art, patent CN 218614312 U discloses a fully automatic vegetable cutter, which includes a feed seat, a roller blade holder, and a blade. The blade is slidably built into the roller blade holder, and the roller blade holder is built into the feed seat. When in use, the roller blade holder is driven to rotate so that the blade cuts the vegetables in the feed seat. Furthermore, the vegetable cutter also includes a pin assembly connected to the motor, one end of which is connected to the roller blade holder to realize transmission from the motor to the roller blade holder. Since the motor and transmission structure of the above-mentioned vegetable cutter can only drive the operation of the vegetable cutting assembly and can only realize the vegetable cutting function, it cannot meet the user's meat cutting needs. The user needs to purchase an additional meat cutter to achieve meat cutting, which greatly increases the cost.
[0005] According to the prior art, the working principle of the vegetable cutting knife assembly is that the motor drives the entire hollow knife barrel to rotate, so that the blades on the knife barrel cut the vegetables. Based on the structure of the knife barrel, it is easy to set a through hole in the knife barrel for the pin shaft assembly to plug in, that is, the solution of the above patent is easy to implement. However, the structure and working principle of the meat cleaver assembly are different from those of the vegetable cutting knife assembly. In order to meet the speed required by the meat cleaver assembly to process meat slices, unlike conventional meat grinders that directly output the speed from the motor to the meat grinder, cutting meat slices requires a lower speed than grinding meat, so the meat cleaver assembly needs to be equipped with a reduction gear. In addition, the meat cleaver assembly is provided with a rotating shaft and multiple rolling cutting blades mounted on the rotating shaft. The rotating shaft is in transmission connection with the reduction gear. In this way, when the motor is working, the rolling cutting blades can output a lower speed through the reduction gear and then through the rotating shaft to cut meat slices. Due to the existence of the reduction gearbox, grease is required inside the reduction gearbox for lubrication of the parts. In order to prevent grease leakage or seepage from contaminating the rolling cutting blade and causing food safety problems, the reduction gearbox needs to be sealed. Under this premise, it is difficult to set the meat cleaver assembly with a through-hole structure like the above-mentioned one for the connection of the pin shaft assembly. This requires that the transmission member and the meat cleaver assembly be connected through other means.
[0006] Therefore, on the basis of ensuring that the vegetable cutter can realize both the vegetable cutting function and the meat cutting function, how to solve the problem of adapting a transmission component to the two processing accessories with large structural differences, the meat cutting knife assembly and the vegetable cutting knife assembly, is currently in need of attention. Utility Model Content
[0007] In order to solve the technical problems in the prior art that vegetable cutters can only realize the vegetable cutting function, meat cutters can only realize the meat cutting function, and one transmission mechanism can only be adapted to drive one knife assembly, resulting in single function, the utility model provides a vegetable cutter, which can drive both the vegetable cutting knife assembly and the meat cutting knife assembly through a set of transmission structure under the premise of using one machine, thereby enriching the processing functions while saving costs.

[0011] The first pivot part is a turn buckle, and a through hole is provided on the bottom wall of the knife cylinder. The second pivot part can extend into the knife cylinder through the through hole. The first pivot part extends into the knife cylinder only when it is aligned with the through hole, and is rotated to deviate from the alignment with the through hole so that the turn buckle is engaged with the bottom wall of the knife cylinder.
[0012] The turn buckle includes a convex rib extending along the stopper toward the through hole and a clamping portion extending and bending toward one side along the top of the convex rib, and the surface of the clamping portion facing the stopper is clamped with the bottom wall of the knife cylinder.
[0013] The transmission head includes a stopper and a boss protruding from the stopper, the first pivot part is a turn buckle, and the turn buckle is arranged on the outer peripheral wall of the boss; or the transmission head includes a boss, the second pivot part is arranged on the side of the boss away from the output shaft of the motor, and the second pivot part is a spline.
[0014] The transmission head includes a stopper, which is a mounting plate. A gap is provided between the first pivot portion and the mounting plate. The vegetable cutting knife assembly includes a knife barrel and a vegetable cutting knife mounted on the knife barrel. When the transmission head and the knife barrel are installed in place, the bottom wall of the knife barrel is clamped in the gap; alternatively, the transmission head includes a stopper, which is a plate-shaped structure.
[0015] The transmission head includes a boss, the second pivot portion is arranged on a side of the boss away from the output shaft of the motor, and the second pivot portion is a spline.
[0016] The processing chamber includes a vegetable cutting chamber and a meat cutting chamber which are arranged in sequence and connected in a direction away from the output shaft of the motor. The vegetable cutter also includes a connecting rod, one end of which is connected to the meat cutting knife assembly, and the other end passes through the vegetable cutting chamber and is connected to the transmission head.

[0018] The transmission head is mounted on the output shaft of the motor; or, the transmission head is mounted on a side wall of the processing chamber facing the output shaft of the motor.
[0019] The vegetable cutting knife assembly includes a first connecting hole, and the meat cutting knife assembly includes a second connecting hole. The aperture of the second connecting hole is larger than the outer diameter of the second pivot portion. When the transmission head is connected to the vegetable cutting knife assembly, the second pivot portion is connected to the first connecting hole. When the transmission head is connected to the meat cutting knife assembly, the second pivot portion extends into the second connecting hole and is loosely fitted with the second connecting hole, and the first pivot portion is connected to the second connecting hole.
[0020] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:
[0021] 1. The vegetable cutter of the present invention optimizes the structure of the transmission head and sets two different pivot parts, so that the same transmission head can be adapted to connect two processing components with large structural differences, which simplifies the configuration of the whole machine while reducing costs and enriching the processing functions of the vegetable cutter. When using, there is no need to replace the transmission head, only the vegetable cutting knife assembly and the meat cutting knife assembly need to be replaced and connected with the corresponding pivot parts, which can save user operations and improve the user experience.
[0022] By adapting and connecting different pivot parts with corresponding processing components, on the premise that the meat cleaver assembly is provided with a reduction gearbox, the vegetable cutting knife assembly and the meat cleaver assembly can output different rotational speeds respectively, which is conducive to better cutting of different ingredients and thus improving the cutting effect of the ingredients.
[0023] The first pivoting portion and the second pivoting portion are arranged at different heights and have different sizes, which are convenient for distinguishing so as to adapt to corresponding knife assemblies, thereby preventing installation errors, reducing installation difficulty and improving installation efficiency.
[0024] 2. As a preferred embodiment, the transmission head includes a stopper for retaining the transmission head on the bottom wall of the cutter barrel. The first pivoting portion and the second pivoting portion are disposed on the stopper. When the transmission head and the cutter barrel are in place, the stopper is located outside the bottom wall of the cutter barrel. The provision of the stopper prevents the transmission head from fully extending into the cutter barrel, thereby preventing the transmission head from engaging with the motor output shaft and effectively securing the transmission head to the cutter barrel. This improves the reliability of the installation of the transmission head and the cutter barrel, while also facilitating the provision of the first pivoting portion and the second pivoting portion.
[0025] As a preferred embodiment of this embodiment, the first pivoting portion is a turnbuckle, and a through-hole is provided on the bottom wall of the knife barrel. The second pivoting portion can extend into the knife barrel through the through-hole. The first pivoting portion only extends into the knife barrel when aligned with the through-hole, and by rotating until it deviates from the through-hole, the turnbuckle is engaged with the bottom wall of the knife barrel. In this embodiment, the user can rotate the knife barrel to achieve relative movement between the knife barrel and the transmission head, thereby rotating the turnbuckle, which is simple to operate. When the turnbuckle is engaged with the bottom wall of the knife barrel, the bottom wall of the knife barrel is clamped and fixed by the stopper and the turnbuckle.
[0026] Furthermore, the turn lock includes a rib extending from the stopper toward the through hole and a snap-on portion extending and bending to one side along the top of the rib. The snap-on portion snaps onto the bottom wall of the knife barrel on a surface facing the stopper. The turn lock is L-shaped, and the snap-on portion facilitates snapping between the turn lock and the knife barrel. The turn lock is provided on the stopper, allowing the second pivot portion to extend directly outward from the stopper.
[0027] 3. As a preferred embodiment, the transmission head includes a stopper and a boss protruding from the stopper, and the first pivoting portion is a turnbuckle disposed on the outer peripheral wall of the boss. In this embodiment, the turnbuckle is disposed on the outer peripheral wall of the boss, which increases the flexibility of the turnbuckle processing. The boss also provides conditions for the protruding arrangement of the second pivoting portion. Assuming a certain connection length between the meat cleaver assembly and the second pivoting portion, arranging the second pivoting portion on the boss facilitates shortening the length of the second pivoting portion compared to directly arranging the second pivoting portion on the stopper.
[0028] Alternatively, the transmission head includes a boss, the second pivot portion is disposed on a side of the boss away from the output shaft of the motor, and the second pivot portion is a spline. By providing the boss, providing the second pivot portion on the boss can shorten the length of the second pivot portion compared to providing the second pivot portion directly on the stopper, provided that the connection length between the meat cleaver assembly and the second pivot portion is constant. Furthermore, the spline structure is simple and easy to manufacture.
[0029] 4. As a preferred embodiment, the transmission head includes a stopper, which is a mounting plate. A gap is defined between the first pivot portion and the mounting plate. The kitchen knife assembly includes a knife barrel and a kitchen knife mounted on the knife barrel. When the transmission head and knife barrel are in place, the bottom wall of the knife barrel engages within the gap. By engaging the bottom wall of the knife barrel within the gap, the gap allows the bottom wall of the knife barrel to be clamped, thereby enhancing the secure connection between the first pivot portion and the knife barrel, promoting synchronous rotation between the two, and improving the stability and reliability of the knife barrel's operation.
[0030] Alternatively, the transmission head includes a stopper, which is a plate-shaped structure. The stopper adopts a plate-shaped structure, which is easy to process and has a large coverage area, thereby achieving reliable position limiting.
[0031] 5. As a preferred embodiment, the processing chamber includes a vegetable cutting chamber and a meat cutting chamber that are sequentially arranged and connected in a direction away from the output shaft of the motor. The vegetable cutting machine also includes a connecting rod, one end of which is connected to the meat cleaver assembly, and the other end passes through the vegetable cutting chamber and is connected to the transmission head. Since the meat cutting chamber is far away from the transmission head, the use of a connecting rod can serve as an intermediate connection to achieve reliable transmission from the transmission head to the meat cleaver assembly. It can be understood that although the vegetable cutting chamber and the meat cutting chamber are connected, the cutting of vegetables and meat are carried out in the corresponding chambers during the processing, and there will be no mixing of different ingredients to cause cross-flavoring. The connection between the vegetable cutting chamber and the meat cutting chamber is mainly to provide conditions for the meat cleaver assembly to pass through the vegetable cutting chamber and connect to the transmission head through the connecting rod.
[0032] As a preferred embodiment of this embodiment, the meat cleaver assembly is inserted into the knife barrel. A through-hole is provided on the bottom wall of the knife barrel. One end of the connecting rod extends through the through-hole into the knife barrel and is transmission-connected to the meat cleaver assembly, while the other end is transmission-connected to the second pivoting portion. In the embodiment in which the knife barrel is provided, the knife barrel is located outside the meat cleaver assembly to provide protection, reducing the possibility of direct contact between the user and the blade of the meat cleaver assembly, thereby improving safety. Furthermore, the connecting rod's passage through the through-hole facilitates connection to the meat cleaver assembly, without increasing installation difficulty.
[0033] 6. As a preferred embodiment, the transmission head is mounted on the output shaft of the motor; alternatively, the transmission head is mounted on the side wall of the processing chamber facing the output shaft of the motor. The transmission head of the present application can be mounted on different parts at different locations, allowing for flexible installation.
[0034] 7. As a preferred embodiment, the vegetable cleaver assembly includes a first connecting hole, and the meat cleaver assembly includes a second connecting hole. The aperture of the second connecting hole is larger than the outer diameter of the second pivot portion. When the transmission head is connected to the vegetable cleaver assembly, the second pivot portion is connected to the first connecting hole. When the transmission head is connected to the meat cleaver assembly, the second pivot portion extends into the second connecting hole to form a clearance fit with the second connecting hole, and the first pivot portion is connected to the second connecting hole. This embodiment enriches the configuration patterns of the first pivot portion, the second pivot portion, and the corresponding components, diversifying the specific form of the transmission head. The first pivot portion and the second pivot portion are both configured to cooperate with the connecting holes, resulting in a simple structure and facilitating the simplification of the transmission head structure.

[0045] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.
[0046] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.
[0047] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
[0048] like Figures 1 to 7As shown, the present application provides a vegetable cutter, comprising a base 10 with a built-in motor 11 and a processing chamber 12 provided on the base 10, the vegetable cutter comprises a vegetable cutter assembly and a meat cutter assembly 13 replaceably provided in the processing chamber 12, and a transmission head 14, the vegetable cutter assembly comprises a knife barrel 17 and a vegetable cutter mounted on the knife barrel 17, the meat cutter assembly 13 comprises a rolling cutter group and a reduction gear box for reducing the speed of the rolling cutter group, the transmission head 14 is engaged with the output shaft 111 of the motor, and the transmission head 14 comprises a gear 111 near the motor. The output shaft 111 of the machine is provided with a first pivot portion 15 and a second pivot portion 16 is provided relative to the first pivot portion 15 and away from the output shaft 111 of the motor. The second pivot portion 16 is protruded relative to the first pivot portion 15. The outer diameter of the first pivot portion 15 is larger than the outer diameter of the second pivot portion 16. One of the first pivot portion 15 and the second pivot portion 16 is adaptively connected to the knife barrel 17 to drive the vegetable cutting knife assembly to rotate, and the other is connected to the rolling cutter group through the reduction gear box to drive the meat cutting knife assembly 13 to work.
[0049] The vegetable cutter of the present invention optimizes the structure of the transmission head 14 and sets two different pivot parts, so that the same transmission head 14 can be adapted to connect two processing components with large structural differences, which simplifies the configuration of the whole machine while reducing costs and enriching the processing functions of the vegetable cutter. When in use, there is no need to replace the transmission head 14, only the vegetable cutting knife assembly and the meat cutting knife assembly 13 need to be replaced and connected with the corresponding pivot parts, which can save user operations and improve user experience.
[0050] By adapting and connecting different pivot parts with corresponding processing components, on the premise that the meat cleaver assembly 13 is provided with a reduction gearbox, the vegetable cutting knife assembly and the meat cleaver assembly 13 can output different rotational speeds respectively, which is conducive to better cutting of different ingredients and thus improving the cutting effect of the ingredients.
[0051] Since the first pivot portion 15 and the second pivot portion 16 are arranged at different heights and have different sizes, they are easy to distinguish so as to adapt to corresponding knife assemblies, thereby preventing installation errors, reducing installation difficulty and improving installation efficiency.
[0052] Specifically, processing chamber 12 may include one or more chambers. When processing chamber 12 is a single-chamber structure, either the vegetable cutter assembly or the meat cleaver assembly 13 is selectively installed in processing chamber 12 to operate. In this case, processing chamber 12 has only one feeding port. When the vegetable cutter assembly is installed, the feeding port of the vegetable cutter assembly corresponds to the feeding port. When the meat cleaver assembly 13 is installed, the feeding port of the meat cleaver assembly 13 corresponds to the feeding port. By interchangeably using the vegetable cutter assembly and the meat cleaver assembly in one processing chamber, one processing chamber can accommodate two different processing assemblies, making the processing chamber more compact, i.e., making the entire machine structure more suitable for home use. When the processing chamber 12 includes a vegetable cutting chamber 121 and a meat cutting chamber 122, the vegetable cutting knife assembly is installed in the vegetable cutting chamber 121 for operation, and the meat cutting knife assembly 13 is installed in the meat cutting chamber 122 for operation, which can avoid the occurrence of odor mixing and mixing of ingredients when different ingredients share the same chamber, and is beneficial to maintaining the quality of each ingredient; the vegetable cutting chamber 121 and the meat cutting chamber 122 have different shapes and / or sizes, for example, and are provided with corresponding openings at the connection position for communication, and the upper parts of the vegetable cutting chamber 121 and the meat cutting chamber 122 are respectively provided with corresponding feeding ports, one feeding port only corresponds to the vegetable cutting chamber 121, and the other feeding port only corresponds to the meat cutting chamber 122, which can further prevent odor mixing, or a larger common feeding port can be provided above the vegetable cutting chamber 121 and the meat cutting chamber 122, which can facilitate the entry of larger ingredients from the feeding port. Furthermore, if Figure 1 、 Figure 5 or Figure 6 As shown, a feeding port 123 is provided above the processing chamber 12, and the number of feeding ports 123 is not limited; a discharging port 124 is provided below the processing chamber 12, and the number of discharging ports 124 is also not limited. Users can use a single machine to cut both vegetables and meat, freeing their hands and greatly improving efficiency.
[0053] The first pivot portion 15 and the second pivot portion 16 are configured as a special-shaped structure to ensure that the transmission head 14 is prevented from rotating after being connected to the vegetable cutting knife assembly and the meat cleaver assembly 13, thereby achieving reliable transmission and improving the operational stability of the vegetable cutting knife assembly and the meat cleaver assembly 13. The first pivot portion 15 and the second pivot portion 16 preferably have different structures to facilitate identification, prevent incorrect installation, and improve installation efficiency.
[0054] As a preferred embodiment, the transmission head 14 includes a stopper 141 for limiting the transmission head 14 on the bottom wall 171 of the knife barrel. The first pivot portion 15 and the second pivot portion 16 are disposed on the stopper 141. When the transmission head 14 and the knife barrel 17 are in place, the stopper 141 is located outside the bottom wall 171 of the knife barrel. The provision of the stopper 141 prevents the transmission head 14 from fully extending into the knife barrel 17, thereby preventing the transmission head 14 from engaging with the output shaft 111 of the motor and effectively securing the transmission head 14 to the knife barrel 17. This improves the reliability of the installation of the transmission head 14 and the knife barrel 17 and facilitates the provision of the first pivot portion 15 and the second pivot portion 16.
[0055] Specifically, for the vegetable cutter assembly, the transmission head 14 drives the knife barrel 17 to rotate so that the vegetable cutter on the knife barrel 17 can cut the vegetables. The vegetable cutter is detachably mounted on the knife barrel 17. Users can replace the vegetable cutter with a different shape according to their needs to achieve slicing, shredding, dicing, etc., thereby meeting the processing needs of different ingredients. Figure 2 As shown, when the knife cylinder 17 is placed horizontally, the bottom wall 171 of the knife cylinder refers to the cylinder wall of the knife cylinder 17 facing the transmission head 14. Preferably, the first pivot portion 15 and the second pivot portion 16 are provided on the side of the stopper 141 facing the knife cylinder 17, and the other side of the stopper 141 is provided with a structure that engages with the output shaft 111 of the motor.
[0056] As a preferred embodiment of this embodiment, the first pivoting portion 15 is a turnbuckle 18. A through hole 172 is provided on the bottom wall 171 of the knife barrel. The second pivoting portion 16 can extend into the knife barrel 17 through the through hole 172. The first pivoting portion 15 only extends into the knife barrel 17 when aligned with the through hole 172. By rotating until it deviates from the alignment with the through hole 172, the turnbuckle 18 is engaged with the bottom wall 171 of the knife barrel. In this embodiment, the user can rotate the knife barrel 17 to achieve relative movement between the knife barrel 17 and the transmission head 14, thereby achieving the screw-on installation of the turnbuckle 18, which is simple to operate.
[0057] like Figure 2 As shown, a solution is shown in which the first pivot portion 15 is provided with four circumferentially evenly distributed turn buckles 18, and the corresponding through holes 172 are cross-shaped. During installation, the user aligns the through holes 172 with the four turn buckles 18, so that the four turn buckles 18 first extend into the knife barrel 17, and then rotates the knife barrel 17 at a certain angle until the turn buckles 18 are engaged with the bottom wall 171 of the knife barrel.
[0058] It is understandable that the number of the rotary buckle 18 can be set according to actual needs, and at least one is set.
[0059] Furthermore, the turn button 18 includes a rib 181 extending along the stopper 141 toward the through hole 172 and a clamping portion 182 extending along the top of the rib 181 and bending toward one side. The surface of the clamping portion 182 facing the stopper 141 is clamped with the bottom wall 171 of the knife barrel. Figure 2 As shown, the turn buckle 18 is L-shaped, and the setting of the clamping portion 182 provides conditions for the turn buckle 18 to be clamped with the knife cylinder 17. The turn buckle 18 is provided on the stopper 141, which provides conditions for the second pivot portion 16 to extend directly outward from the stopper 141.
[0060] In one embodiment, the first pivot portion 15 is provided with four circumferentially evenly distributed turn buckles 18, and the second pivot portion 16 is protruded outward along the center of the stopper 141 (the second pivot portion 16 is located on the inner side of the four turn buckles 18), and the second pivot portion 16 is, for example, a spline.
[0061] As a preferred embodiment, the transmission head 14 includes a stopper 141 and a boss 142 protruding from the stopper 141. The first pivot portion 15 is a turnbuckle disposed on the outer peripheral wall of the boss 142. In this embodiment, the turnbuckle is disposed on the outer peripheral wall of the boss 142, which increases the flexibility of the turnbuckle processing. The boss 142 also provides conditions for the protruding arrangement of the second pivot portion 16. Assuming a certain connection length between the meat cleaver assembly 13 and the second pivot portion 16, the second pivot portion 16 is disposed on the boss 142, which can shorten the length of the second pivot portion 16 compared to directly disposing the second pivot portion 16 on the stopper 141.
[0062] Specifically, in one embodiment, Figure 7 The diagram illustrates an example of a stopper 141 having a boss 142, for example, a cylindrical boss 142. In this embodiment, the first pivoting portion 15 comprises multiple knobs disposed on the outer circumference of the boss 142. To simplify the knob structure, the knobs are, for example, strip-shaped blocks projecting radially outward from the outer circumference of the boss 142. When the first pivoting portion 15 is mounted on the blade cylinder 17, the blade cylinder 17 is provided with a through hole. The first pivoting portion 15 extends into the blade cylinder 17 only when aligned with the through hole. By rotating until it deviates from alignment with the through hole, the knobs engage with the bottom wall 171 of the blade cylinder.
[0063] As a preferred embodiment, the transmission head 14 includes a stopper 141, which serves as a mounting plate. A gap is defined between the first pivot portion 15 and the mounting plate. The vegetable cutting knife assembly includes a knife barrel 17 and a vegetable cutting knife mounted on the knife barrel 17. When the transmission head 14 and the knife barrel 17 are in place, the bottom wall 171 of the knife barrel engages within the gap. With the bottom wall 171 of the knife barrel engaged within the gap, the gap allows the bottom wall of the knife barrel 17 to be clamped, thereby enhancing the secure connection between the first pivot portion 15 and the knife barrel 17, promoting their synchronous rotation, and improving the operational stability and reliability of the knife barrel 17.
[0064] In this embodiment, the first pivot portion 15 can adopt the structure of the above-mentioned turn buckle 18, or it can be other structures. For example, the first pivot portion 15 includes a shaft body and a limiting portion provided at the end of the shaft body. A gap is formed between the limiting portion and the mounting plate. The limiting portion and the through hole 172 can be interference fit. When the limiting portion is inserted into the knife cylinder 17 through the through hole 172, the bottom wall 171 of the knife cylinder is locked in the gap.
[0065] As a preferred embodiment, the transmission head 14 includes a stopper 141, which is a plate-shaped structure. The stopper 141 adopts a plate-shaped structure, which is easy to process and has a large coverage area, and can achieve reliable limiting. The stopper 141 can be made of Figures 2 to 4 or Figure 7 The circular plate can be used, and plates of other shapes such as square can also be used.
[0066] In a preferred embodiment, the transmission head 14 includes a boss 142. The second pivot portion 16 is disposed on a side of the boss 142 away from the motor output shaft 111. The second pivot portion 16 is a spline. By providing the boss 142, the length of the second pivot portion 16 can be shortened by disposing the second pivot portion 16 on the boss 142, compared to disposing the second pivot portion 16 directly on the stop 141, provided that the connection length between the meat cleaver assembly 13 and the second pivot portion 16 is constant. Furthermore, the spline structure is simple and easy to manufacture.
[0067] In one embodiment, Figure 7 As shown, the boss 142 is a columnar boss 142. In another embodiment, the first pivot portion 15 is a cross-shaped structure, for example. In this case, the middle area of the cross-shaped structure can be used as the boss 142.
[0068] As a preferred embodiment, the processing chamber 12 includes a vegetable cutting chamber 121 and a meat cutting chamber 122, which are arranged in sequence and connected in a direction away from the output shaft 111 of the motor. The vegetable cutter also includes a connecting rod 19, one end of which is connected to the meat cleaver assembly 13, and the other end of which passes through the vegetable cutting chamber 121 and is connected to the transmission head 14. Because the meat cutting chamber 122 is far from the transmission head 14, the use of the connecting rod 19 can serve as an intermediate connection, achieving reliable transmission from the transmission head 14 to the meat cleaver assembly 13. Specifically, the reduction gearbox of the meat cleaver assembly 13 is transmission-connected to the rolling cutter assembly. The second pivot portion 16 of the transmission head 14 is transmission-connected to the reduction gearbox via the connecting rod 19, thereby indirectly achieving transmission connection between the second pivot portion 16 and the rolling cutter assembly.
[0069] like Figure 1 、 Figure 5 or Figure 6As shown, the meat-cutting chamber 122 is provided with an opening at one end away from the vegetable-cutting chamber 121, which allows the vegetable-cutting knife assembly and the meat-cutting knife assembly 13 to be pushed into the processing chamber 12 or pulled out from the processing chamber 12 laterally, which saves effort for the user. In one embodiment, a discharge port 124 is provided below the meat-cutting chamber 122. In the meat-cutting state, the processed meat slices are discharged from the discharge port 124; in the vegetable-cutting state, the processed vegetables can be discharged from the discharge port 124 or thrown out from the opening. In another embodiment, a discharge port 124 is provided below both the vegetable-cutting chamber 121 and the meat-cutting chamber 122 to facilitate the discharge of processed ingredients from the corresponding discharge port 124, thereby preventing the vegetables from carrying the meat smell when passing through the meat-cutting chamber 122, thereby affecting the taste of the vegetables.
[0070] The connecting rod 19 is a rod-shaped structure. Figure 6 As shown, the length of the connecting rod 19 is sufficient to ensure that the end of the connecting rod 19 facing the transmission head 14 can be connected to the transmission head 14 when the connecting rod 19 is arranged horizontally. Preferably, the connecting rod 19 is first assembled with the meat cleaver assembly 13, and then the meat cleaver assembly 13 is pushed horizontally into the meat cleaver cavity 122 through the lateral opening of the meat cleaver cavity 122. When pushed into place, the connecting rod 19 is plug-connected with the transmission head 14, which simplifies the installation method.
[0071] As a preferred embodiment of this embodiment, the meat cleaver assembly 13 is inserted into a knife barrel 17. A through hole 172 is provided in the bottom wall 171 of the knife barrel. One end of a connecting rod 19 extends through through hole 172 into the knife barrel 17 and is transmission-connected to the meat cleaver assembly 13. The other end is transmission-connected to the second pivot portion 16. In the embodiment in which the knife barrel 17 is provided, the location of the knife barrel 17 outside the meat cleaver assembly 13 provides protection, reducing the possibility of a user directly touching the blade of the meat cleaver assembly 13 and improving safety. Furthermore, the connection of the connecting rod 19 to the meat cleaver assembly 13 is facilitated by the through hole 172, without increasing installation difficulty.
[0072] like Figure 3 As shown, in the scheme where the connecting rod 19 is transmission-connected to the second pivot portion 16, the first pivot portion 15 is used for transmission connection with the vegetable cleaver assembly. In the vegetable cutting state, the knife barrel 17 and the vegetable cleaver form the vegetable cleaver assembly. In this case, the through hole 172 is used to cooperate with the first pivot portion 15 to achieve the engagement between the first pivot portion 15 and the knife barrel 17. In the meat cutting state, the knife barrel 17 is separated from the vegetable cleaver, and the meat cleaver assembly 13 is inserted into the knife barrel 17. In this case, the through hole 172 provides clearance for the connecting rod 19, allowing the connecting rod 19 to pass through the through hole 172 and transmission connection with the meat cleaver assembly 13. The second pivot portion 16 is, for example, a spline, and the connecting rod 19 is provided with an axial hole 191 that cooperates with the spline.
[0073] The present application does not specifically limit the location of the transmission head 14. For example, in one embodiment, Figure 4As shown, the transmission head 14 is mounted on the output shaft 111 of the motor, and the transmission head 14 is engaged with the output shaft 111 of the motor. A clearance hole for the first pivot portion 15 and the second pivot portion 16 to pass through is provided on the side wall of the processing chamber 12 facing the transmission head 14, so that the first pivot portion 15 and the second pivot portion 16 extend into the processing chamber 12 to be transmission-connected with the corresponding knife assembly when cutting vegetables or cutting meat. Alternatively, in another embodiment, the transmission head 14 is mounted on the side wall of the processing chamber 12 facing the output shaft 111 of the motor, wherein the first pivot portion 15 and the second pivot portion 16 are located in the processing chamber 12, and one end of the transmission head 14 facing the output shaft 111 of the motor is located outside the processing chamber 12, so that when the processing chamber 12 is installed in place, the transmission head 14 is plug-connected with the output shaft 111 of the motor. The transmission head 14 of the present application can be installed on different components at different positions, and the arrangement is flexible.
[0074] As a preferred embodiment, the vegetable cutting knife assembly includes a first connecting hole, and the meat cutting knife assembly 13 includes a second connecting hole. The aperture of the second connecting hole is larger than the outer diameter of the second pivot portion. When the transmission head 14 is connected to the vegetable cutting knife assembly, the second pivot portion is connected to the first connecting hole. When the transmission head 14 is connected to the meat cutting knife assembly 13, the second pivot portion extends into the second connecting hole and fits with the second connecting hole clearance, and the first pivot portion is connected to the second connecting hole.
[0075] This embodiment enriches the configuration patterns of the first pivot part, the second pivot part and the corresponding components, diversifying the specific form of the transmission head 14, and the first pivot part and the second pivot part are both configured to cooperate with the connecting hole, which has a simple structure and is conducive to the simplification of the structure of the transmission head 14.
[0076] Specifically, the first pivot portion and the second pivot portion can both be configured as spline structures, located at different heights of the transmission head 14 and having different outer diameters, so that one transmission head 14 can be adapted to two sizes of connection holes. This allows the transmission head 14 to be adapted to either the vegetable cutting knife assembly or the meat cleaver assembly 13 without having to replace the transmission head 14. Users only need to replace the knife assembly according to their vegetable or meat cutting needs, which reduces costs while saving user operations and improving ease of use. Both the first and second connection holes utilize an axial hole structure that cooperates with the spline, resulting in a simple structure and easy installation by plugging into the spline. Furthermore, for the meat cleaver assembly 13 equipped with a reduction gearbox, this does not damage the sealing of the reduction gearbox, thereby preventing grease leakage from the reduction gearbox and contaminating the processed food.
[0077] Based on the specific configuration of the processing chamber 12, the transmission head 14 can be coordinated with the various processing assemblies in the following manner. In one embodiment, when only one processing chamber 12 is provided, the vegetable cutting knife assembly and the meat cleaver assembly 13 can be interchangeably installed in the processing chamber 12. When the vegetable cutting knife assembly is fully installed, the first connecting hole on the knife barrel 17 is in driving connection with the second pivoting portion; when the meat cleaver assembly 13 is fully installed, the second connecting hole on the knife holder passes over the second pivoting portion and is in driving connection with the first pivoting portion.
[0078] In another embodiment, the processing chamber 12 includes a vegetable cutting chamber 121 and a meat cutting chamber 122 which are arranged in sequence and connected in a direction away from the output shaft 111 of the motor, and the meat cutting knife assembly 13 includes a connecting rod extending toward the output shaft 111 of the motor, and the second connecting hole is provided at the end of the connecting rod; when the vegetable cutting knife assembly is used, the vegetable cutting knife assembly is installed in the vegetable cutting chamber 121, and the first connecting hole provided on the knife cylinder 17 is transmission connected to the second pivot part; when the meat cutting knife assembly 13 is used, the meat cutting knife assembly 13 is installed in the meat cutting chamber 122, and at this time the connecting rod passes through the vegetable cutting chamber 121 so that the second connecting hole passes over the second pivot part and is transmission connected to the first pivot part.
[0079] In another embodiment, the processing chamber 12 includes a meat cutting chamber 122 and a vegetable cutting chamber 121 which are arranged in sequence and connected in a direction away from the output shaft 111 of the motor, and the vegetable cutting knife assembly includes a connecting rod extending toward the output shaft 111 of the motor, and the first connecting hole is provided at the end of the connecting rod; when the vegetable cutting knife assembly is used, the vegetable cutting knife assembly is installed in the vegetable cutting chamber 121, and the connecting rod passes through the meat cutting chamber 122 so that the first connecting hole is transmission-connected to the second pivot portion; when the meat cutting knife assembly 13 is used, the meat cutting knife assembly 13 is installed in the meat cutting chamber 122, and the second connecting hole passes over the second pivot portion and is transmission-connected to the first pivot portion.
