Description

Technical Field

[0001] This utility model relates to the field of household appliances technology, specifically to a food processing machine. Background Technology

[0002] Existing food processors typically consist of a main unit with a built-in drive unit and a mixing cup located below the main unit. The mixing cup contains a stirring rod driven by the drive unit, and the stirring rod has a transmission groove that is detachably connected to the output end of the drive unit. When using the food processor to process ingredients, the user first needs to install the stirring rod in the mixing cup, then add the ingredients, and then install the main unit above the mixing cup with its output end connected to the stirring rod, driving the stirring rod to rotate and achieve mixing. However, when adding ingredients to the mixing cup, especially when adding flour to make dough, it is easy for flour to be poured into the transmission groove. Flour accumulates in the transmission groove, preventing the output end of the drive unit from fully inserting into the transmission groove, resulting in an ineffective transmission connection. Furthermore, powder enters the output end of the drive unit, making it difficult to clean. Since the live parts cannot be rinsed for cleaning, this can lead to risks such as unpleasant odors and transmission misalignment over time. When users clean the flour in the transmission groove, they need to disassemble the stirring rod, pour out the ingredients or remove them with their fingers before cleaning. Cleaning is very inconvenient and wastes ingredients. Furthermore, when reinstalling the stirring rod into the cup, the bottom of the cup is covered with flour, making it difficult for users to install. Even after prying open the shaft covering the bottom of the cup to insert the stirring rod, there is still a lot of flour between the stirring rod and the shaft, causing the stirring rod to make a lot of noise when it rotates.

[0003] To address the aforementioned issues, the applicant's earlier patent application CN215687143U disclosed a food processor that is easy to clean. This processor features a transmission groove on the stirring rod that is detachably connected to the output end of a drive device. An opening on the side wall of the rod connects to the transmission groove via a connecting channel. This allows the food, especially flour, to be discharged into the stirring cup through the opening if accidentally spilled into the transmission groove, preventing accumulation and difficulty in cleaning. However, users have found that some flour remains in the transmission groove as it moves downwards, particularly between the meshing teeth. When the output end of the drive device engages with the transmission groove, the presence of flour causes misalignment and jamming. Furthermore, during kneading, dough clumps enter the connecting channel through the opening, pushing the powder upwards to the point where the output end of the drive device engages with the transmission groove, further resulting in powder residue at the output end and severely impacting the user experience. Utility Model Content

[0004] The purpose of this invention is to provide a food processing machine that solves the problem that in the existing food processing machine, powder easily enters the output end of the drive device during the dough kneading function, causing the output end of the drive device to not be properly connected to the stirring rod and to become stuck.

[0005] To achieve the above objectives, this utility model provides a food processing machine, including a cup body with a built-in stirring element and a processing chamber, and a main unit disposed above the cup body. The main unit is provided with a drive device that is driven and connected to the stirring element. The stirring element is detachably connected to the drive device. The stirring element includes a blade shaft and blades connected to the blade shaft. The top end of the blade shaft is provided with a meshing part that is driven and connected to the output end of the drive device. A dustproof cover is also provided at the meshing part. The dustproof cover has a first state in which it is closed above the meshing part to prevent the meshing part from communicating with the outside world, and a second state in which the meshing part is driven and connected to the output end of the drive device.

[0006] This application features a meshing part at the top of the cutter shaft that is connected to the output end of the drive device. This allows the output end of the drive device to accurately connect with the meshing part after the user assembles the main unit and the cup, thus transmitting power from the drive device to the mixing component. Furthermore, the meshing part is covered with a dustproof cover. This cover has two states: a first state where it is closed above the meshing part to prevent communication between the meshing part and the outside world, and a second state where the meshing part is connected to the output end of the drive device. Specifically, when the user adds ingredients, especially powdery ingredients such as flour, into the processing chamber, the dustproof cover remains in the first state, isolating the meshing part from the outside world and effectively preventing powdery ingredients from entering. After adding the ingredients, the dustproof cover can be switched to the second state, allowing the output end of the drive device to smoothly engage with the meshing part, thus achieving effective power transmission. This effectively prevents ingredients from accumulating on the meshing part during addition, which could cause the output end of the drive device to jam or even fail to engage with the meshing part, resulting in transmission obstruction. This ensures that the output end of the drive device can smoothly engage with the meshing part, guaranteeing transmission stability. Furthermore, it ensures the cleanliness of the main unit, requiring only a wipe-down; rinsing is unnecessary. This better protects the internal electrical components, helping to extend their lifespan. It also keeps the mixing parts clean, making cleaning easier and eliminating powder buildup areas—a simple rinse is all it takes. Simultaneously, it prevents food from moving upwards through the transmission channel and entering the main unit, protecting all internal components and ensuring the overall stability of the machine.

[0007] In a preferred embodiment of a food processing machine, the powder-proof cover includes a powder-guiding part disposed on the top of the powder-proof cover. The outer diameter of the powder-guiding part gradually increases from top to bottom, and the maximum outer diameter of the powder-guiding part is the maximum outer diameter of the powder-proof cover. The top of the powder-guiding part is raised upward in an arc shape or a sharp corner.

[0008] By designing the powder-proof cover to include a powder-guiding section at its top, with the outer diameter of the powder-guiding section gradually increasing from top to bottom, the food can smoothly slide down the inclined surface of the powder-guiding section when the user pours it into the processing chamber. This prevents food from falling directly onto the top of the powder-proof cover and causing accumulation or residue, further reducing the risk of food entering the meshing part and eliminating the need for the user to manually remove the food. Simultaneously, the top of the powder-guiding section is raised upwards in an arc or pointed shape, making it easier for food to slide down its surface when poured in, further preventing food residue or jamming.

[0009] In a preferred embodiment of a food processing machine, the meshing part is a transmission groove with an open top, the inner peripheral wall of the transmission groove has radially protruding meshing teeth, and a dust-proof cover is provided on the transmission groove.

[0010] By designing the meshing part as a transmission groove with an open top, and the inner circumferential wall of the transmission groove having radially protruding meshing teeth, the output end of the drive device can achieve a stable transmission connection with the transmission groove through the meshing teeth when it extends into the transmission groove, thereby ensuring the stability of power transmission. Furthermore, the dust-proof cover installed on the transmission groove ensures that food does not enter the transmission groove during the process of adding food to the processing chamber, thus preventing food accumulation in the transmission groove and avoiding unstable meshing between the output end of the drive device and the transmission groove.

[0011] In a preferred embodiment of a food processing machine, the wall of the dustproof cover extends to cover the outside of the transmission groove, and the inner surface of the cover wall is provided with a limiting rib extending downward into the transmission groove to radially limit the transmission groove.

[0012] By extending the wall of the anti-powder cover to cover the outside of the transmission groove, and providing a limiting rib on the inner surface of the cover wall that extends downward into the transmission groove to radially limit its movement, the anti-powder cover, when placed outside the transmission groove, achieves improved stability through the engagement of the limiting rib with the inner wall of the transmission groove. This prevents the anti-powder cover from shifting or falling off due to impacts from food during food addition, ensuring it remains in the correct position and fulfills its crucial role of isolating food from the transmission groove. Furthermore, the engagement of the limiting rib with the transmission groove and the engagement of the cover wall with the outside of the transmission groove provides dual limiting for both the anti-powder cover and the cutter shaft, further enhancing the stability of their connection.

[0013] In a preferred embodiment of a food processing machine, the dustproof cover is a flexible component, and the top of the dustproof cover is provided with multiple elastic sheets. In a first state, a connecting seam is formed between two adjacent elastic sheets to prevent powder from entering the meshing part. In a second state, the output end of the drive device presses down the cantilever end of the elastic sheet to pass through the dustproof cover and drively connect with the meshing part.

[0014] By making the anti-powder cover a flexible component, the top of the cover has multiple elastic plates. In the first state, a connecting seam is formed between two adjacent elastic plates to prevent powder from entering the meshing part. In the second state, the output end of the drive device presses down on the cantilever end of the elastic plate to pass through the anti-powder cover and connect with the meshing part. This allows the elastic plates of the anti-powder cover to effectively prevent food from entering the transmission groove when the user adds food into the processing cavity. When the food is added and the main unit is engaged with the cup, the output end of the drive device presses down on the elastic plates from top to bottom. Under the downward pressure of the output end of the drive device, the elastic plates undergo elastic deformation and separate from each other, allowing the output end of the drive device to pass smoothly through the anti-powder cover and engage with the meshing teeth in the transmission groove, thereby achieving stable power transmission. After the main unit is separated from the cup, the elastic plates can return to the first state under their own elastic force, so that the anti-powder cover can always be fixed on the cutter shaft without repeated disassembly and assembly. This not only improves the convenience of use and effectively reduces the complexity of user operation, but also prevents the anti-powder cover from being lost or damaged after being separated from the cutter shaft, thus improving the user experience. Preferably, the elastic sheet bulges upward from the outer edge to the center, making the entire powder shield present an upward bulging arc shape, thereby effectively preventing powder from accumulating on the top of the powder shield. More preferably, an opening communicating with the transmission groove can be provided on the cutter shaft, so that even if powder falls when the elastic sheet is pressed down, it can be discharged outward through the opening, further preventing powder from accumulating in the transmission groove.

[0015] In a preferred embodiment of a food processing machine, a dust-proof cover is detachably provided on the engaging part.

[0016] By making the anti-powder cover a detachable cover on the meshing part, when the user needs to add materials into the processing chamber, the anti-powder cover can be installed above the meshing part to block the food; when the main unit and the cup body need to be connected, the anti-powder cover can be removed to facilitate the connection between the output end of the drive device and the meshing part, which improves the flexibility of use.

[0017] In a preferred embodiment of a food processing machine, the dust shield is separately configured from the cutter shaft.

[0018] By setting the dust shield to be separate from the cutter shaft, users can remove the dust shield for cleaning or replacement, ensuring the cleanliness and functional stability of the food processor during long-term use.

[0019] In a preferred embodiment of a food processing machine, the dustproof cover includes a cover body disposed outside the meshing part and a connecting part connecting the cover body and the cutter shaft. The cover body can be rotated around the connecting part to switch between a first state and a second state.

[0020] By including a cover body covering the outside of the meshing part and a connecting part connecting the cover body and the cutter shaft, and the cover body being able to rotate around the connecting part to switch between a first state and a second state, the powder-proof cover can maintain its connection with the cutter shaft while switching states by rotating, without the need for complete disassembly. This not only avoids the situation where the powder-proof cover is lost or damaged after the user separates it from the cutter shaft, but also allows the cutter shaft to gently collide and squeeze the dough during rotation, which helps to improve the dough's elasticity.

[0021] In a preferred embodiment of a food processing machine, the cutter shaft has an outwardly extending boss, and the connecting part has a through hole that engages with the boss; or, The connecting part is integrally formed with the cutter shaft.

[0022] By providing an outwardly extending boss on the cutter shaft and a through hole in the connecting part that engages with the boss, the cover can be quickly installed and removed through the engagement of the boss and the through hole. This allows users to more easily complete the cleaning and installation operations when they want to clean or replace the dust cover, further improving ease of use.

[0023] By making the connecting part and the cutter shaft integrally molded, the step of connecting and fixing the powder shield to the cutter shaft is eliminated, which helps to improve assembly efficiency and at the same time ensures the stability of the connection between the powder shield and the cutter shaft.

[0024] In a preferred embodiment of a food processing machine, the cutter shaft is provided with radially outwardly extending annular ribs, and the bottom of the dust-proof cover is assembled to the annular ribs; or, The cutter shaft is provided with radially outward extending annular ribs, and the top surface of the annular ribs is provided with a warning area to remind users to install the anti-powder cover before use.

[0025] By providing radially outward-extending annular ribs to the cutter shaft, and assembling the bottom of the dustproof cover to the annular ribs, the dustproof cover can achieve stable positioning and installation by cooperating with the annular ribs, further improving the stability of the dustproof cover during use.

[0026] By providing a warning area on the top surface of the annular rib to remind users to install the anti-powder cover before use, users can see the warning area when putting food into the processing chamber, thus reminding them to install the anti-powder cover in time. This avoids the situation where food falls directly into the meshing part due to omission of installation, making it difficult for the output end of the drive device to cooperate with the meshing part, and further improves the user experience.

Detailed Implementation

[0029] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0030] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1 to 9As shown, this utility model provides a food processing machine, including a cup body 3 with a built-in stirring element 4 and a processing chamber 31, and a main unit 1 disposed above the cup body 3. The main unit 1 is provided with a drive device 2 that is driven and connected to the stirring element 4. The stirring element 4 is detachably connected to the drive device 2. The stirring element 4 includes a blade shaft 41 and blades connected to the blade shaft 41. The top end of the blade shaft 41 is provided with a meshing part that is driven and connected to the output end of the drive device 2. A dustproof cover 5 is also provided on the outside of the meshing part. The dustproof cover 5 has a first state of being closed above the meshing part to prevent the meshing part from communicating with the outside, and a second state of being driven and connected between the meshing part and the output end of the drive device 2.

[0032] This application provides a meshing part at the top of the cutter shaft 41 that is connected to the output end of the drive device 2, so that after the user assembles the main unit 1 and the cup body 3, the output end of the drive device 2 can be accurately connected to the meshing part, thereby realizing the transmission of power from the drive device 2 to the stirring component 4. Furthermore, a powder-proof cover 5 is provided on the outer side of the meshing part. The powder-proof cover 5 has a first state in which it is closed above the meshing part to block the meshing part from communicating with the outside world, and a second state in which the meshing part is connected to the output end of the drive device 2. That is, when the user puts food, especially powdery food such as flour, into the processing chamber 31, the powder-proof cover 5 can be kept in the first state to isolate the meshing part from the outside world and effectively prevent powdery food from entering the meshing part. After adding the food, the powder-proof cover 5 can be switched to the second state so that the output end of the drive device 2 can smoothly cooperate with the meshing part, thereby realizing the effective transmission of power of the drive device 2. This effectively avoids the problem of food accumulating on the meshing part when adding food, which would cause the output end of the drive device 2 to get stuck or even unable to cooperate with the meshing part, resulting in transmission obstruction. This ensures that the output end of the drive device 2 can smoothly cooperate with the meshing part and ensures the stability of the transmission. Furthermore, it ensures the cleanliness of the main unit 1, requiring only a wipe-down without rinsing, thus better protecting the internal electrical components and extending their service life. It also maintains the cleanliness of the mixing component 4, making it easier to clean and eliminating powder accumulation blind spots; a simple rinse is all it takes. Simultaneously, it prevents food from moving upwards through the transmission groove 411 and entering the main unit 1, protecting the internal components and ensuring the stability of the entire machine.

[0033] In this application, the drive device 2 specifically refers to the motor and the gearbox connected to the motor for transmission. The output end of the gearbox is detachably connected to the stirring component 4.

[0034] It should be noted that this application does not specifically limit the structure of the powder shield 5. As one preferred embodiment of this application, such as... Figure 3As shown, the anti-powder cover 5 includes a powder guiding part 52 disposed on the top of the anti-powder cover 5. The outer diameter of the powder guiding part 52 gradually increases from top to bottom, and the maximum outer diameter of the powder guiding part 52 is the maximum outer diameter of the anti-powder cover 5. The top of the powder guiding part 52 is raised upward in an arc shape or a sharp angle. Specifically, as shown... Figure 3 , Figure 6 , Figure 7 As shown, the top of the powder guiding part 52 is raised upward in an arc shape, and at this time the top of the entire powder guiding cover is a point; when the powder guiding part 52 is raised upward in a sharp angle, it can be understood that the powder guiding part 52 is conical in shape, which can be a cone or a pyramid, and a fixing part sleeved on the outside of the cutter shaft 41 is provided below the cone to realize the connection between the anti-powder cover 5 and the cutter shaft 41.

[0035] By configuring the anti-powder cover 5 to include a powder guiding part 52 located on top of the anti-powder cover 5, the outer diameter of the powder guiding part 52 gradually increases from top to bottom, allowing the food to slide smoothly along the inclined surface of the powder guiding part 52 when the user pours the food into the processing cavity 31. This prevents the food from falling directly onto the top of the anti-powder cover 5 and causing accumulation or residue, further reducing the risk of food entering the meshing part and eliminating the need for the user to manually peel the food off. At the same time, the top of the powder guiding part 52 is raised upward in an arc shape or raised upward in a sharp angle, making it easier for the food to slide along the surface of the powder guiding part 52 when poured in, further preventing food residue or jamming.

[0036] It should also be noted that this application does not specifically limit the structure of the meshing part; it can be a solid transmission column with meshing teeth on its side wall, and the output end of the drive device 2 has a meshing groove that mates with the transmission column. As a preferred embodiment of this application, such as... Figure 2 As shown, the meshing part is a transmission groove 411 with an open top. The inner circumferential wall of the transmission groove 411 has meshing teeth that bulge radially inward. The dustproof cover 5 is installed on the outside of the transmission groove 411.

[0037] By configuring the meshing part as a transmission groove 411 with an open top, and the inner circumferential wall of the transmission groove 411 having radially protruding meshing teeth, the output end of the drive device 2 can achieve a stable transmission connection with the transmission groove 411 through the meshing teeth when it extends into the transmission groove 411, thereby ensuring the stability of power transmission. Furthermore, the anti-powder cover 5 is installed on the outside of the transmission groove 411 to ensure that food does not enter the transmission groove 411 during the process of adding food into the processing chamber 31, thus preventing the accumulation of food inside the transmission groove 411 and avoiding unstable meshing between the output end of the drive device 2 and the transmission groove 411.

[0038] It should be further noted that this application does not specifically limit the structure of the powder shield 5 in this embodiment, and it can be any one of the following embodiments: Example 1: As Figure 2As shown, in this embodiment, the wall of the dustproof cover 5 extends to cover the outside of the transmission groove 411, and the inner surface of the cover wall is provided with limiting ribs 51 that extend downward into the transmission groove 411 to radially limit the transmission groove 411. Of course, the dustproof cover is not limited to the above-described configuration, such as... Figure 9 As shown, the anti-powder cover 5 can also be fixed by the insertion and connection of the limiting rib and the transmission groove 411. The structure of the anti-powder cover 5 can also ensure that the anti-powder cover 5 blocks the powder.

[0039] By extending the wall of the anti-powder cover 5 to cover the outside of the transmission groove 411, and providing a limiting rib 51 extending downward into the transmission groove 411 to radially limit its movement, the anti-powder cover 5, when placed outside the transmission groove 411, engages with the inner wall of the transmission groove 411 through the limiting rib 51. This further enhances the stability of the anti-powder cover 5's installation, preventing it from shifting or falling off due to impacts from food during food addition. This ensures the anti-powder cover 5 remains in the correct position, fulfilling its crucial role of isolating food from the transmission groove 411. Furthermore, the engagement of the limiting rib 51 with the transmission groove 411 and the engagement of the cover wall with the outside of the transmission groove 411 achieves dual limiting of the anti-powder cover 51 and the cutter shaft 41, further improving the stability of the connection between the anti-powder cover 5 and the cutter shaft 411.

[0040] It should be noted that this application does not specifically limit the structure of the lower limiting rib 51 in this embodiment, such as... Figure 3 As shown, as a preferred embodiment of this application, the limiting rib 51 is annular and abuts against the inner sidewall of the transmission groove 411. Of course, it is also possible to provide multiple limiting ribs 51, which are spaced apart along the circumference.

[0041] Example 2: Figure 6 , Figure 7 As shown, in this embodiment, the anti-powder cover 5 is a flexible component, and the top of the anti-powder cover 5 is provided with multiple elastic sheets 55. In the first state, a connecting seam is formed between two adjacent elastic sheets 55 to prevent powder from entering the meshing part. In the second state, the output end of the drive device 2 presses down the cantilever end of the elastic sheet 55 to pass through the anti-powder cover 5 and be connected to the meshing part in a transmission manner.

[0042] By setting the anti-powder cover 5 as a flexible component, the top of the anti-powder cover 5 is provided with multiple elastic sheets 55. In the first state, a connecting seam is formed between two adjacent elastic sheets 55 to prevent powder from entering the meshing part. In the second state, the output end of the drive device 2 presses down on the cantilever end of the elastic sheet 55 to pass through the anti-powder cover 5 and drively connect with the meshing part, so that when the user adds food to the processing cavity 31, the elastic sheet 55 of the anti-powder cover 5 can effectively prevent food from entering the transmission groove 411. When the food is added and the main unit 1 is engaged with the cup body 3, the output end of the drive device 2 presses down on the elastic sheet 55 from top to bottom, and the elastic sheet 55 is driven by the drive device. Under the downward pressure of the output end of device 2, the elastic plate 55 undergoes elastic deformation and separates from each other, allowing the output end of device 2 to smoothly pass through the anti-powder cover 5 and engage with the meshing teeth in the transmission groove 411, thereby achieving stable power transmission. After the main unit 1 separates from the cup body 3, the elastic plate 55 can return to the first state under its own elastic force, so that the anti-powder cover 5 can always be fixed on the cutter shaft 41 without repeated disassembly and assembly. This not only improves the convenience of use and effectively reduces the complexity of user operation, but also avoids the loss or damage of the anti-powder cover 5 after the user separates it from the cutter shaft 41, thus improving the user experience. Preferably, the elastic plate 55 is raised upward from the outer edge to the center, so that the anti-powder cover 5 has an upwardly raised arc shape, thereby effectively preventing powder from accumulating on the top of the anti-powder cover 5. More preferably, an opening communicating with the transmission groove 411 can be provided in the cutter shaft 41. When the elastic plate 55 is pressed down, even if powder falls, it can be discharged outward through the opening, further preventing powder from accumulating in the transmission groove 411.

[0043] In this embodiment, this application does not specifically limit whether the anti-powder cover 5 is detachable relative to the cutter shaft 41, such as Figure 6 As shown, it can be directly fixed to the cutter shaft 41, or it can be detachable from the cutter shaft 41 depending on the usage, which will not be elaborated here.

[0044] like Figure 2 As shown, when the meshing part is the transmission groove 411 as described above, the cutter shaft 41 may also be provided with a connecting channel that connects the transmission groove 411 and the processing cavity 31. The transmission groove 411 and the connecting channel are connected to form a material discharge channel.

[0045] It should be noted that this application does not specifically limit the relative positional relationship between the dustproof cover 5 and the engaging part. As a preferred embodiment of this application, such as Figures 2 to 5 As shown, the dustproof cover 5 is detachably mounted on the engaging part.

[0046] By setting the anti-powder cover 5 as a detachable cover on the meshing part, when the user needs to add materials into the processing chamber 31, the anti-powder cover 5 can be installed above the meshing part to block the food; when the main unit 1 and the cup body 3 need to be matched, the anti-powder cover 5 can be removed to facilitate the connection between the output end of the drive device 2 and the meshing part, which improves the flexibility of use.

[0047] It should be further noted that this application does not specifically limit the relative position of the anti-powder cover 5 and the cutter shaft 41 in this embodiment, and it can be any of the following embodiments: Implementation method 1: such as Figure 2 As shown, in this embodiment, the anti-powder cover 5 is separately disposed from the cutter shaft 41.

[0048] By setting the anti-powder cover 5 to be separate from the cutter shaft 41, users can remove the anti-powder cover 5 for cleaning or replacement, ensuring the cleanliness and functional stability of the food processing machine during long-term use.

[0049] Implementation method 2: such as Figure 4 , Figure 5 As shown, in this embodiment, the anti-powder cover 5 includes a cover body 53 covering the outside of the meshing part and a connecting part 54 connecting the cover body 53 and the cutter shaft 41. The cover body 53 can be rotated around the connecting part 54 to switch between a first state and a second state.

[0050] By including a cover 53 covering the outside of the meshing part and a connecting part 54 connecting the cover 53 and the cutter shaft 41, and the cover 53 being able to rotate around the connecting part 54 to switch between a first state and a second state, the anti-powder cover 5 can maintain its connection with the cutter shaft 41 while switching states by rotating, without the need for complete disassembly. This not only avoids the situation where the user loses or damages the anti-powder cover 5 after separating it from the cutter shaft 41, but also allows the cutter shaft 41 to gently collide and squeeze the dough during rotation, which is beneficial to improving the dough's elasticity.

[0051] Furthermore, it should be noted that this application does not specifically limit how the connecting part 54 is connected to the cutter shaft 41 in this embodiment, and it can be any of the following embodiments: Example 1: As Figure 4 As shown, in this embodiment, the cutter shaft 41 is provided with an outwardly extending boss 413, and the connecting part 54 is provided with a through hole that engages with the boss 413.

[0052] By providing an outwardly extending boss 413 on the cutter shaft 41 and a through hole that engages with the boss 413 on the connecting part 54, the cover 53 can be quickly installed and disassembled through the engagement of the boss 413 and the through hole. This allows users to more easily complete the cleaning and installation operations when they want to clean or replace the dustproof cover 5, further improving the ease of use.

[0053] Furthermore, such as Figure 4 As shown, the cutter shaft 41 is provided with an annular rib 412 extending radially outward, and a boss 413 is provided on the top surface of the annular rib 412 and extends upward; of course, the boss 413 can also extend directly outward from the side wall of the cutter shaft 41.

[0054] Example 2: Figure 5 As shown, in this embodiment, the connecting part 54 is integrally formed with the cutter shaft 41.

[0055] By making the connecting part 54 and the cutter shaft 41 integrally molded, the step of connecting and fixing the anti-powder cover 5 and the cutter shaft 41 is eliminated, which helps to improve assembly efficiency and at the same time ensures the stability of the connection between the anti-powder cover 5 and the cutter shaft 41.

[0056] Furthermore, such as Figure 5 As shown, the cutter shaft 41 is provided with an annular rib 412 extending radially outward, and the connecting part 54 is integrally formed on the annular rib 412.

[0057] As a preferred embodiment of this application, such as Figure 2 , Figure 6 As shown, the cutter shaft 41 is provided with an annular rib 412 extending radially outward, and the bottom of the anti-powder cover 5 is assembled to the annular rib 412.

[0058] By providing a radially outwardly extending annular rib 412 to the cutter shaft 41, and assembling the bottom of the anti-powder cover 5 to the annular rib 412, the anti-powder cover 5 can achieve stable positioning and installation by cooperating with the annular rib 412, further improving the stability of the anti-powder cover 5 during use.

[0059] Specifically, such as Figure 2 As shown, when the anti-powder cover 5 is detachably installed above the engaging part, the anti-powder cover 5 extends downwards from top to bottom above the annular rib 412 and overlaps the annular rib 412, thereby providing axial support for the anti-powder cover 5; Figure 6 As shown, when the anti-powder cover 5 is fixed on the cutter shaft 41, the anti-powder cover 5 is provided with a fitting part that is clamped to the outside of the annular rib 412.

[0060] As a preferred embodiment of this application, such as Figure 8As shown, the cutter shaft 41 is provided with an annular rib 412 extending radially outward, and the top surface of the annular rib 412 is provided with a warning area 4121 to remind the user to install the anti-powder cover 5 before use.

[0061] By providing a warning area 4121 on the top surface of the annular rib 412 to remind users to install the anti-powder cover 5 before use, users can see the warning area 4121 directly when putting food into the processing cavity 31, thus reminding users to install the anti-powder cover 5 in time. This avoids the situation where food falls directly into the meshing part due to omission in installation, making it difficult for the output end of the drive device 2 to cooperate with the meshing part, thereby further improving the user experience.
