Description

Technical Field

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

[0002] Existing portable food processors typically consist of a main body and a cup mounted on top of it. The main body houses a motor and a battery that powers the motor. The cup contains a mixing element connected to the motor. When using the food processor, the user places ingredients into the cup, and the mixing element rotates at high speed driven by the motor to process the ingredients. Due to the portability requirement of portable food processors and the need for a large battery to power the motor, the motor and cup are usually limited in size, resulting in a smaller space for grinding the ingredients. In the above situations, in order to improve the crushing effect of food, some manufacturers will set the mixing component at a higher position inside the mixing cup. Therefore, the motor shaft needs to extend far beyond the bottom wall of the mixing cup. At the same time, in order to achieve the positioning of the motor shaft, a bearing is usually installed between the machine base and the motor shaft, which is sleeved on the outside of the motor shaft. The bearing achieves radial positioning of the motor shaft. However, after the above settings, the distance between the bearing positioning point and the top of the motor shaft is far. This results in the mixing component connected to the top of the motor shaft having low coaxiality with the motor shaft. Consequently, the mixing component will wobble when rotating. The vibration caused by the wobbling will cause the whole machine to vibrate and make noise, which seriously affects the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a portable food processing machine to solve the problem that in existing portable food processing machines, the distance between the mixing component and the bearing that positions the motor shaft is too far, resulting in low coaxiality between the mixing component and the motor shaft and easy wobbling during rotation.

[0004] To achieve the above objectives, this utility model provides a portable food processing machine, including a machine body and a cup body disposed above the machine body. The machine body contains a motor and a battery that supplies power to the motor. The cup body contains a stirring component that is connected to the motor for transmission. The machine body includes a base. The bottom end of the cup body is open and closedly connected to the base. The base has an upwardly extending and hollow mounting platform. The center of the mounting platform has a clearance hole through which the motor shaft of the power supply motor passes. The motor includes a motor body and a motor cover. The motor cover has a limiting platform that extends into the mounting platform. The limiting platform contains a bearing sleeved on the outside of the motor shaft.

[0005] This application features an upwardly extending, hollow mounting platform on the base. The platform has a clearance hole at its center for the motor shaft to pass through, allowing the motor shaft to connect with the stirring components inside the container. The upward protrusion of the mounting platform significantly shortens the distance between the top wall of the base and the stirring components, reducing the upward extension length of the motor shaft. Simultaneously, the motor cover has a limiting platform extending into the mounting platform, containing a bearing fitted onto the outside of the motor shaft. This cooperation between the limiting platform and the mounting platform ensures the coaxiality of the motor cover and the base, thereby guaranteeing the overall... The coaxiality of the motor and the base is ensured to prevent uneven spacing between the motor shaft and the clearance hole, which could cause friction and collision when the motor shaft rotates. On the other hand, the limiting platform is set inside the mounting platform, which helps to reduce the distance between the limiting platform and the mixing component, thereby reducing the distance between the bearing and the mixing component. This allows the bearing to be radially positioned closer to the mixing component, effectively preventing the mixing component from wobbling at high speeds due to a large distance between the mixing component and the bearing. This improves the stability of the mixing component's rotation and reduces the vibration of the entire machine during operation.

[0006] In a preferred embodiment of a portable food processing machine, the inner side wall of the mounting platform and the limiting platform are further provided with positioning structures.

[0007] By providing a positioning structure on the inner wall of the mounting platform and the limiting platform, the mounting platform and the limiting platform can achieve precise positioning through the positioning structure, further improving the coaxiality of the mounting platform and the limiting platform, and thus further improving the coaxiality of the whole machine, ensuring the stability of the motor driving the stirring components to rotate, and further improving the stability of the whole machine operation.

[0008] In a preferred embodiment of a portable food processing machine, the inner wall of the top of the mounting platform is provided with a positioning step with a reduced inner diameter, and the limiting platform is provided with a first positioning section extending laterally inward and a second positioning section extending upward from the first positioning section. The first positioning section abuts against the bottom wall of the positioning step and the second positioning section abuts against the side wall of the positioning step. The positioning structure includes the positioning step, the first positioning section and the second positioning section.

[0009] By setting the positioning structure to include a positioning step, a first positioning section, and a second positioning section, when the motor cover and the base are assembled, the first positioning section can achieve axial positioning with the bottom wall of the positioning step, while the second positioning section can achieve radial positioning with the side wall of the positioning step. Furthermore, the outer wall of the limiting platform and the inner wall of the mounting platform can also achieve radial positioning. This achieves dual radial positioning of the base and the motor cover, which helps to further improve the coaxiality of the motor and the base and ensure the stability of the entire machine operation.

[0010] In a preferred embodiment of a portable food processing machine, the mounting platform is further provided with a shaft seal for sealing the clearance hole. The shaft seal includes a first sealing part clamped between the outer wall of the second positioning section and the side wall of the positioning step, and a second sealing part clamped between the top wall of the second positioning section and the inner top wall of the mounting platform.

[0011] By incorporating a shaft seal within the mounting platform that also seals the clearance hole, the sealing of the mounting platform and the limiting platform is ensured. This prevents slurry from entering the limiting platform through the gap between the motor shaft and the clearance hole during food processing, which could lead to moisture damage or unstable rotation of bearings and other components. It also ensures the stability of bearing rotation and prevents lubricating grease from entering the cup and contaminating the food. Furthermore, the shaft seal includes a first sealing part clamped between the outer wall of the second positioning section and the side wall of the positioning step, and a second sealing part clamped between the top wall of the second positioning section and the inner top wall of the mounting platform. This allows the shaft seal to be positioned through the clamping of various structures, ensuring its positional stability and preventing displacement of the shaft seal over prolonged use, which could lead to a decrease in sealing performance or even failure.

[0012] In a preferred embodiment of a portable food processing machine, the bottom of the base is further provided with an annular noise reduction cavity that surrounds the outside of the limiting platform and is concave upward.

[0013] By providing an annular noise reduction cavity that surrounds the limiting platform and is concave at the bottom of the base, on the one hand, the noise generated when the motor rotates can be attenuated by collision within the annular noise reduction cavity, reducing the transmission of noise to the outside world and playing a role in noise reduction; on the other hand, it can reduce the amount of material used for demolding the base, which can not only reduce the weight of the whole machine and make it easier for users to handle, but also reduce production costs.

[0014] In a preferred embodiment of a portable food processor, the annular noise reduction cavity is provided with multiple vertically extending dividing ribs to divide the annular noise reduction cavity into multiple segments.

[0015] By incorporating multiple vertically extending dividing ribs within the annular noise reduction cavity, the cavity is divided into several segments. This divides the cavity into smaller chambers, allowing noise to collide within these chambers, significantly increasing the probability and area of ​​collision between noise and the inner wall of the cavity, thereby enhancing the noise reduction effect. Furthermore, the dividing ribs also increase the strength of the base, preventing deformation when subjected to significant forces.

[0016] In a preferred embodiment of a portable food processor, the top of the base is provided with a recessed annular mounting groove, and a sealing element is provided in the mounting groove, which is clamped between the bottom of the cup body and the mounting groove.

[0017] By providing a recessed annular mounting groove at the top of the base, and a sealing element inside the mounting groove, the sealing element is clamped between the bottom of the cup body and the mounting groove. This allows the sealing element to be radially limited by the annular mounting groove, ensuring that the sealing element remains within the annular mounting groove when the cup body and the base are assembled, thus guaranteeing its sealing effect and preventing the sealing element from shifting during assembly, which could lead to poor sealing or even failure.

[0018] In a preferred embodiment of a portable food processor, the base is provided with a mating part extending upward to the outside of the cup body, the bottom of the cup body is provided with a connecting part fixedly connected to the mating part, and the inner side wall of the connecting part is also provided with a pressing ring extending downward. The bottom end of the connecting part and the bottom end of the pressing ring abut against the top wall of the sealing element.

[0019] By providing a downwardly extending crimping ring on the inner wall of the connecting part, and having the bottom end of the connecting part and the bottom end of the crimping ring abut against the top wall of the seal, the cup body can not only achieve crimping of the seal through the connecting part, but also achieve double crimping through the crimping ring, thereby improving the fixing effect on the seal and further ensuring the stability of the seal position. At the same time, the connecting part and the crimping ring achieve double sealing inside and outside after crimping the seal, which helps to further improve the sealing effect.

[0020] In a preferred embodiment of a portable food processing machine, the distance L between the top of the bearing and the top of the motor shaft satisfies: 10mm≤L≤20mm.

[0021] By setting the distance L between the top of the bearing and the top of the motor shaft to satisfy 10mm≤L≤20mm, we can avoid the situation where the distance between the top of the bearing and the top of the motor shaft is too small, resulting in the mixing component being too narrow from the top wall of the base, making it easy for food to get stuck between them and difficult to clean. At the same time, we can avoid the situation where the distance between the top of the bearing and the top of the motor shaft is too large, resulting in a poor positioning effect of the bearing on the top of the motor shaft, causing the mixing component and the motor shaft to have low coaxiality and wobble.

[0022] In a preferred embodiment of a portable food processing machine, the motor cover is provided with an outwardly extending cantilever, the base bottom wall is provided with a fixed column that is fixedly connected to the cantilever, and a shock-absorbing pad is provided between the fixed column and the cantilever.

[0023] By incorporating an outwardly extending cantilever on the motor's upper cover and a fixed post on the base's bottom wall that is rigidly connected to the cantilever, the entire motor is connected to the base via the cantilever and the fixed post. Compared to connecting the motor to the base via a larger motor bracket, this significantly reduces the contact area between the motor and the base, thereby reducing the transmission of vibrations generated during motor rotation to the base and the entire machine, lowering the overall vibration amplitude, and improving the stability of the machine's operation. Simultaneously, a shock-absorbing pad is installed between the fixed post and the cantilever; the buffering and damping effect of the pad further reduces the transmission of vibrations to the base.

Detailed Implementation

[0032] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0033] 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.

[0034] like Figures 1 to 5 As shown, this utility model provides a portable food processing machine, including a machine body and a cup body 1 located above the machine body. The machine body is equipped with a motor 3 and a battery 2 that supplies power to the motor 3. The cup body 1 is equipped with a stirring component 4 that is connected to the motor 3 for transmission. The machine body includes a base 5. The bottom end of the cup body 1 is open and closedly connected to the base 5. The base 5 is equipped with an upwardly extending and hollow mounting platform 51. The center of the mounting platform 51 is equipped with a clearance hole 511 through which the motor shaft 31 of the power supply motor 3 passes. The motor 3 includes a motor body 32 and a motor cover 33. The motor cover 33 is equipped with a limiting platform 331 that extends into the mounting platform 51. The limiting platform 331 is equipped with a bearing 8 that is sleeved on the outside of the motor shaft 31.

[0035] This application provides an upwardly extending and hollow mounting platform 51 for the base 5. The mounting platform 51 has a clearance hole 511 at its center for the motor shaft 31 of the power supply 3 to pass through, allowing the motor shaft 31 to connect with the stirring component 4 inside the cup body 1 after passing through the clearance hole 511. Due to the upward protrusion of the mounting platform 51, the distance between the top wall of the base 5 and the stirring component 4 is greatly shortened, reducing the upward extension length of the motor shaft 31. Simultaneously, the motor cover 33 has a limiting platform 331 extending into the mounting platform 51. The limiting platform 331 contains a bearing 8 sleeved on the outside of the motor shaft 31. On the one hand, the cooperation between the limiting platform 331 and the mounting platform 51 ensures the coaxiality of the motor cover 33 and the base 5. This ensures the coaxiality of the entire motor 3 and the base 5, preventing uneven spacing between the motor shaft 31 and the clearance hole 511, which could cause friction and collision when the motor shaft 31 rotates. On the other hand, the limiting platform 331 is set inside the mounting platform 51, which helps to reduce the distance between the limiting platform 331 and the mixing component 4, thereby reducing the distance between the bearing 8 and the mixing component 4. This makes the radial positioning of the bearing 8 on the motor shaft 31 closer to the mixing component 4, effectively preventing the mixing component 4 from swaying at high speed due to a large distance between the mixing component 4 and the bearing 8, improving the stability of the rotation of the mixing component 4, and reducing the vibration of the whole machine during operation.

[0036] As a preferred embodiment of this application, such as Figure 2 As shown, the inner wall of the mounting platform 51 and the limiting platform 331 are also provided with positioning structures.

[0037] By providing a positioning structure on the inner side wall of the mounting platform 51 and the limiting platform 331, the mounting platform 51 and the limiting platform 331 can achieve precise positioning through the positioning structure, further improving the coaxiality of the mounting platform 51 and the limiting platform 331, thereby further improving the coaxiality of the whole machine, ensuring the stability of the motor 3 driving the stirring component 4 to rotate, and further improving the stability of the whole machine operation.

[0038] It should be noted that this application does not specifically limit the positioning structure; as one preferred option in this application, such as... Figure 2 , Figure 3 , Figure 4 As shown, the inner sidewall of the top of the mounting platform 51 is provided with a positioning step 512 with a reduced inner diameter. The limiting platform 331 is provided with a first positioning section 3311 extending laterally inward and a second positioning section 3312 extending upward from the first positioning section 3311. The first positioning section 3311 abuts against the bottom wall of the positioning step 512 and the second positioning section 3312 abuts against the side wall of the positioning step 512. The positioning structure includes the positioning step 512, the first positioning section 3311 and the second positioning section 3312.

[0039] By configuring the positioning structure to include a positioning step 512, a first positioning segment 3311, and a second positioning segment 3312, when the motor cover 33 is assembled with the base 5, the first positioning segment 3311 can achieve axial positioning with the bottom wall of the positioning step 512, while the second positioning segment 3312 can achieve radial positioning with the side wall of the positioning step 512. Furthermore, the outer wall of the limiting platform 331 and the inner wall of the mounting platform 51 can also achieve radial positioning. This achieves dual radial positioning of the base 5 and the motor cover 33, which helps to further improve the coaxiality of the motor 3 and the base 5 and ensure the stability of the whole machine operation.

[0040] Furthermore, such as Figure 4 As shown, the mounting platform 51 is also provided with a shaft seal 7 for sealing the clearance hole 511. The shaft seal 7 includes a first sealing part 71 clamped between the outer wall of the second positioning section 3312 and the side wall of the positioning step 512, and a second sealing part 72 clamped between the top wall of the second positioning section 3312 and the inner top wall of the mounting platform 51.

[0041] By providing a shaft seal 7 within the mounting platform 51 to seal the clearance hole 511, the sealing of the mounting platform 51 and the limiting platform 331 is ensured. This prevents the slurry from entering the limiting platform 331 through the gap between the motor shaft 31 and the clearance hole 511 during food processing, which could cause moisture damage to components such as the bearing 8, resulting in unstable rotation or even damage. This ensures the stability of the bearing 8's rotation and also prevents the grease used to lubricate the bearing 8 from entering the cup body 1 and contaminating the food. Furthermore, the shaft seal 7 includes a first sealing part 71 clamped between the outer wall of the second positioning section 3312 and the side wall of the positioning step 512, and a second sealing part 72 clamped between the top wall of the second positioning section 3312 and the inner top wall of the mounting platform 51. This allows the shaft seal 7 to be positioned by the clamping between the various structures, ensuring its positional stability and preventing the shaft seal 7 from shifting after prolonged use, which could lead to a decrease in sealing performance or even failure.

[0042] As a preferred embodiment of this application, such as Figure 2 As shown, the bottom of the seat is also provided with an annular noise reduction cavity 52 that surrounds the outside of the limiting platform 331 and is concave upward.

[0043] By providing an annular noise reduction cavity 52 that surrounds the outer side of the limiting platform 331 and is concave upward at the bottom of the base 5, on the one hand, the noise generated when the motor 3 rotates can be attenuated by collision within the annular noise reduction cavity 52, reducing the transmission of noise to the outside world and playing a role in noise reduction; on the other hand, it can reduce the amount of material used for demolding the base 5, which can not only reduce the weight of the whole machine and make it easier for users to handle, but also reduce production costs.

[0044] Furthermore, the annular noise reduction cavity 52 is provided with multiple vertically extending dividing ribs to divide the annular noise reduction cavity 52 into multiple segments.

[0045] By providing multiple vertically extending dividing ribs inside the annular noise reduction cavity 52, the annular noise reduction cavity 52 is divided into multiple segments. On the one hand, dividing the annular noise reduction cavity 52 into multiple small cavities allows noise to collide within multiple small cavities, greatly increasing the probability and area of ​​noise colliding with the inner wall of the cavity, and further improving the noise reduction effect. On the other hand, the dividing ribs can increase the strength of the base 5 and prevent the base 5 from deforming when subjected to large forces.

[0046] As a preferred embodiment of this application, such as Figure 4 As shown, the top of the base 5 is provided with a recessed annular mounting groove 54, and a sealing element 6 is provided in the mounting groove. The sealing element 6 is clamped between the bottom end of the cup body 1 and the mounting groove.

[0047] By providing a recessed annular mounting groove 54 at the top of the base 5, and a sealing element 6 inside the mounting groove, and clamping the sealing element 6 between the bottom of the cup body 1 and the mounting groove, the sealing element 6 can be radially limited by the annular mounting groove 54. This ensures that when the cup body 1 is assembled with the base 5, the sealing element 6 can remain within the annular mounting groove 54 to guarantee its sealing effect, and avoids the situation where the sealing element 6 shifts during the assembly of the cup body 1 and the base 5, resulting in poor sealing effect or even failure of the sealing element 6.

[0048] Furthermore, such as Figure 4 As shown, the base 5 has a mating part that extends upward to the outside of the cup body 1. The bottom of the cup body 1 has a connecting part 11 that is fixedly connected to the mating part. The inner side wall of the connecting part 11 also has a pressing ring 12 that extends downward. The bottom end of the connecting part 11 and the bottom end of the pressing ring 12 abut against the top wall of the sealing element 6.

[0049] By providing a downwardly extending crimping ring 12 on the inner sidewall of the connecting part 11, and having the bottom end of the connecting part 11 and the bottom end of the crimping ring 12 abut against the top wall of the sealing element 6, the cup body 1 can not only achieve crimping of the sealing element 6 through the connecting part 11, but also achieve double crimping through the crimping ring 12, thereby improving the fixing effect on the sealing element 6 and further ensuring the stability of the position of the sealing element 6. At the same time, the connecting part 11 and the crimping ring 12 also achieve double sealing inside and outside after crimping the sealing element 6, which helps to further improve the sealing effect.

[0050] It should be noted that this application does not specifically limit the distance between the top of the bearing 8 and the top of the motor shaft 31. As a preferred embodiment of this application, such as... Figure 2 As shown, the distance L between the top of the bearing 8 and the top of the motor shaft 31 satisfies: 10mm≤L≤20mm.

[0051] By setting the distance L between the top of the bearing 8 and the top of the motor shaft 31 to satisfy: 10mm≤L≤20mm, the situation is avoided where the distance between the top of the bearing 8 and the top of the motor shaft 31 is too small, resulting in the mixing component 4 being too narrow from the top wall of the base 5, making it easy for food to get stuck between them and difficult to clean; at the same time, the situation is avoided where the distance between the top of the bearing 8 and the top of the motor shaft 31 is too large, resulting in a poor positioning effect of the bearing 8 on the top of the motor shaft 31, causing the mixing component 4 to have low coaxiality with the motor shaft 31 and thus wobble.

[0052] As a preferred embodiment of this application, such as Figure 4 As shown, the motor cover 33 is provided with an outwardly extending cantilever 332, and the bottom wall of the base 5 is provided with a fixing column 53 that is fixedly connected to the cantilever 332. A shock-absorbing pad 9 is provided between the fixing column 53 and the cantilever 332.

[0053] By providing an outwardly extending cantilever 332 to the motor cover 33 and a fixed post 53 to be fixedly connected to the cantilever 332 on the bottom wall of the base 5, the motor 3 is connected to the base 5 via the cantilever 332 and the fixed post 53. Compared to connecting the motor 3 to the base 5 via a larger motor bracket, this significantly reduces the contact area between the motor 3 and the base 5, thereby reducing the transmission of vibration generated by the motor 3 during rotation to the base 5 and the entire machine, reducing the overall vibration amplitude, and improving the stability of the machine's operation. Simultaneously, a shock-absorbing pad 9 is provided between the fixed post 53 and the cantilever 332. The shock-absorbing pad 9 further reduces the transmission of vibration to the base 5 through its buffering and damping effect.

[0054] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
