[0002] A food processor is a food processing machine that integrates functions such as blending, crushing, and grinding. It can efficiently process food and release nutrients, and has gained widespread recognition in the market. A food processor typically consists of a cup assembly, a base assembly, a blade assembly, and a drive motor. The drive motor is installed inside the base assembly and fixed by a mounting bracket. The motor shaft passes through the cup assembly and connects to the blade assembly, with a seal around the perforation in the cup assembly.

[0003] However, traditional food processors, which typically use rigid connectors such as metal frames or hard plastic parts to fix the motor and container assembly and seal gaps with independent sealing rings or mechanical seals, have several problems. On the one hand, the complex installation structure of the drive motor and seals requires high machining precision, increasing manufacturing costs. On the other hand, they are prone to malfunctions during use; for example, rigid connectors are susceptible to leakage due to long-term vibration or wear accumulation, leading to loose motor installations, affecting machine reliability and shortening service life. Therefore, there is an urgent need to optimize the installation of the drive motor and the shaft sealing structure to reduce costs, lower failure rates, and improve the performance and lifespan of food processors.

[0004] Therefore, it is necessary to propose a new technical solution to overcome the shortcomings of existing technologies. Utility Model Content

[0039] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0040] Please see Figures 1 to 12 As shown, this utility model provides a food processing machine 100, which includes a barrel assembly 1, a motor 3 disposed outside the barrel assembly 1, and a pulverizing element 4 disposed inside the barrel assembly 1. The motor 3 drives the pulverizing element 4 to move through an output shaft 31 that passes through the barrel assembly 1. The food processing machine 100 also includes a mounting base 5 made of soft rubber, which is disposed between the barrel assembly 1 and the motor 3 and has a sealing portion surrounding the output shaft 31. The barrel assembly 1, the mounting base 5, and the motor 3 are connected by fasteners 6. The fasteners 6 directly connect the barrel assembly 1 and the motor 3, allowing the motor 3 to be mounted against the mounting base 5, and the mounting base 5 is in a clamping state between the barrel assembly 1 and the motor 3.

[0041] The food processing machine 100 provided by this utility model uses a mounting base 5 made of soft rubber. The barrel assembly 1, the mounting base 5, and the motor 3 are connected by fasteners 6. The fasteners 6 directly connect the barrel assembly 1 and the motor 3, allowing the motor 3 to be mounted against the mounting base 5. The mounting base 5 is clamped between the barrel assembly 1 and the motor 3. With this configuration, the mounting base 5 not only serves to fix the motor 3 in place, but also provides sealing, heat insulation, and vibration damping. This simplifies the assembly process, reduces manufacturing costs, and significantly improves the operational stability and sealing reliability of the food processing machine 100.

[0042] Please see Figures 1 to 3 As shown, in some embodiments, the food processor 100 may specifically be a food processor, a soymilk maker, a high-speed blender, etc. In this embodiment, the food processor 100 mainly includes a bucket assembly 1, a base assembly 2, a motor 3, a crushing component 4, and a mounting base made of soft rubber 5.

[0043] In this embodiment, the bucket assembly 1 includes a bucket body 11 and a heating plate 12 fixed to the bottom of the bucket body. The bucket body 11 is a cylindrical shape that extends vertically, and the heating plate 12 is sealed and installed at the bottom of the bucket body 11, forming the bottom wall of the bucket body 11. The heating plate 12 and the bucket body 11 together enclose a food processing cavity. In other embodiments, the bucket body 11 may also be configured to have a bottom wall integrally formed with the peripheral sidewalls, with the bottom wall and the peripheral sidewalls enclosing the food processing cavity; furthermore, the heating plate 12 may be disposed on the outside of the bottom wall of the bucket body 11. For some food processors that do not require heating, the bucket assembly 1 may not have a heating plate 12.

[0044] The motor 3 is installed inside the base assembly 2, and its output shaft 31 extends upward and passes through the barrel 11, with the upper end of the output shaft 31 connected to the crushing component 4. In this embodiment, the output shaft 31 is the motor shaft. In other embodiments, the output shaft 31 may also be a shaft driven by the motor 3 through a transmission mechanism. The crushing component 4 is specifically a blade, which is driven to rotate by the output shaft 31 to crush ingredients such as beans, grains, and vegetables. The mounting base 5 is disposed between the bottom wall of the barrel 11 and the motor 3. The mounting base 5 is made of soft elastic materials such as silicone or elastic TPU, and it forms a clamping and fixing structure with the barrel assembly 1 and the motor 3 through fasteners 6. In this embodiment, the motor 3 is bottom-mounted, that is, the motor 3 is located below the barrel assembly 1; in other embodiments, the motor 3 may be side-mounted, that is, the motor 3 may be located to the side of the barrel assembly 1. This application does not limit the specific position of the motor 3.

[0045] Please see Figures 3 to 7As shown, in this embodiment, the mounting base 5 has a flat cylindrical structure with a shaft mounting hole 51 at its center for the output shaft 31 to pass through. Four through holes 52 are evenly distributed around the circumference of the mounting base 5, and a sealing rib 521 surrounds the through holes 52 on the upper surface of the mounting base 5. The fastener 6 passes through the bottom wall of the barrel assembly 1 and the mounting base 5 from top to bottom and connects to the motor 3. In this embodiment, the heating plate 12 forms the bottom wall of the barrel assembly 1, and the fastener 6 passes through the screw hole on the heating plate 12 and the through hole 52 on the mounting base 5 from top to bottom before being locked into the threaded hole on the motor 3 housing. When the fastener 6 is tightened, the heating plate 12 and the motor 3 housing exert axial compression on the mounting base 5, and the sealing rib 521 forms an interference seal with the heating plate 12 under compression deformation. In this embodiment, the fastener 6 is specifically a bolt, the portion of which is threaded onto the housing of the motor 3, while the end passing through the through hole 52 of the mounting base 5 may not have threads. The fastener 6 directly connects the bucket assembly 1 and the motor 3, that is, the fastener 6 connects both the bucket assembly 1 and the motor 3 simultaneously, rather than through the mounting base 5. The mounting base 5 allows the motor 3 to be mounted against it through this direct connection, and the mounting base 5 is clamped between the bucket assembly 1 and the motor 3. In this embodiment, the mounting base 5 is provided with a mounting groove 54, and the motor 3 has a boss protruding from the mounting groove 54.

[0046] Furthermore, the mounting base 5 is provided with a double-layer sealing structure at the shaft mounting hole 51. Specifically, the sealing part includes an upper sealing part 551 and a lower sealing part 552 that are spaced apart in the axial direction of the output shaft 31. Figure 6 and Figure 7 As shown, the sealing part includes an upper sealing part 551 and a lower sealing part 552 spaced apart along the axis of the output shaft 31. In this embodiment, both the upper sealing part 551 and the lower sealing part 552 are annular sealing lips integrally injection molded with the mounting base 5, and their inner diameter is slightly smaller than the diameter of the output shaft 31. The lower surface of the sealing lip is inclined to facilitate the output shaft 31 to pass through from bottom to top, and the sealing lip forms a line contact seal with the output shaft 31. In this embodiment, the sealing part is integrally molded with the mounting base 5, which reduces the number of parts, simplifies the structure, and facilitates installation.

[0047] Please continue reading. Figure 6 and Figure 7As shown, in this embodiment, a liquid accumulation chamber 56 is formed between the double-layer sealing structures. That is, a liquid accumulation chamber 56 is formed between the upper sealing part 551 and the lower sealing part 552. The mounting base 5 has a drainage channel 53 that connects the liquid accumulation chamber 56 and the outside of the mounting base 5 to drain the liquid in the liquid accumulation chamber 56 from the mounting base 5. The drainage channel 53 is provided on the side wall of the mounting base 5. In this embodiment, the drainage channel 53 is in the shape of a stepped hole, so that the drainage pipe 7 can be inserted into the large-diameter section of the stepped hole, and the opening of the drainage pipe 7 can safely cover the small-diameter section of the hole, so as to realize the smooth entry of the accumulated liquid into the drainage pipe 7. The base of the food processing machine 100 is provided with one or more structures of the following, namely, a liquid outlet, a liquid guide groove, and a liquid collection box, corresponding to the outlet of the drainage pipe 7, to drain the leaked liquid. The liquid outlet is a hole through which liquid is discharged from the food processor 100. It can be a specially designed hole for liquid discharge or a ventilation hole on the base. The liquid guide groove is a groove that guides the liquid flow. It can be a channel that directs the liquid to the liquid outlet or a liquid collection box. The liquid collection box is a container for collecting liquid. It can be a box that is detachably installed on the base and can be removed to pour out the collected liquid after collection. It can also be a cavity formed on the base. With the above configuration, when a small amount of liquid breaks through the seal of the upper sealing part 551, it will enter the liquid accumulation chamber 56 and be directed out through the drainage channel 53, preventing the liquid from further breaking through the lower sealing part 552 and entering the motor 3.

[0048] Please see Figures 8 to 11 As shown, in some other embodiments, at least one of the upper sealing portion 551 and the lower sealing portion 552 is a sealing ring assembly 57 mounted on the mounting base 5. Figure 8 and Figure 9 In the illustrated embodiment, the upper sealing portion 551 is a sealing ring assembly 57, and the lower sealing portion 552 is still a sealing lip integrally formed with the mounting base 5. Figure 10 and Figure 11 In the illustrated embodiment, both the upper sealing part 551 and the lower sealing part 552 are sealing ring assemblies 57.

[0049] Specifically, the mounting base 5 has a mounting groove 58, and the sealing ring assembly 57 is installed in the mounting groove 58 by an interference fit. Figure 11 As shown, the mounting base 5 has an assembly groove 58 coaxially arranged with the shaft mounting hole 51. The sealing ring assembly 57 is pressed into the assembly groove 58 through an interference fit. Since the mounting base 5 is made of soft rubber and the sealing ring assembly 57 is also an elastic sealing component, the two can be installed by elastic deformation to achieve an interference fit, without the need for a separate fitting structure. The structure is simple and installation is convenient. Please refer to... Figure 12As shown, in this embodiment, the sealing ring assembly 57 includes a support frame 571, a soft rubber component, and an elastic rubber ring 574. The support frame 571 can be an L-shaped cross-section ring formed by stamping a metal sheet, such as stainless steel. The soft rubber component has a covering portion 572 covering the support frame 571 and a contact portion 573 located inside the covering portion 572. The covering portion 572 can be covered onto the outer surface of the support frame 571 by secondary injection molding, or it can be assembled onto the outer surface of the support frame 571. The covering portion 572 is in sealing contact with the inner wall of the assembly groove 58. The contact portion 573 is located inside the covering portion 572 and is used to form a sealing contact with the output shaft 31. The inner wall of the contact portion 573 is provided with a protruding ring for contacting the output shaft 31, and the outer wall of the contact portion 573 is provided with an annular groove, in which the elastic rubber ring 574 is assembled. The elastic rubber ring 574 is used to generate a preload to enhance the sealing between the contact portion 573 and the output shaft 31. When the output shaft 31 is inserted, the elastic rubber ring 574 is compressed and deformed. This structure combines rigid support with elastic sealing, making it particularly suitable for high-frequency vibration conditions. In other embodiments, one or both of the upper sealing portion 551 and the lower sealing portion 552 may also be an O-ring seal mounted on the mounting base 5.

[0050] The assembly process of one embodiment of the food processing machine 100 provided by this utility model is as follows: First, the mounting base 5 is installed correspondingly to the motor 3, so that the output shaft 31 of the motor 3 passes through the shaft mounting hole 51 in the center of the mounting base 5, and the screw hole on the motor 3 housing corresponds to the through hole 52 on the mounting base 5; then, the mounting base 5 and the motor 3 are aligned with the mounting holes on the bottom wall of the barrel, and the fasteners 6 are inserted from top to bottom and tightened; finally, the crushing component 4 is installed inside the barrel 11 on the output shaft 31. The tightening degree of the fasteners 6 ensures that the mounting base 5 is subjected to a certain amount of compression deformation, so that the elastic restoring force generated by the soft rubber material of the mounting base 5 can keep the sealing interfaces in stable contact.

[0051] As described above, the food processing machine 100 provided by this utility model reduces the number of parts and simplifies the assembly process by replacing the traditional metal bracket and independent sealing ring with a soft rubber mounting base 5. Furthermore, the elastic deformation of the soft rubber material automatically compensates for axial dimensional tolerances, preventing sealing failure due to processing errors; the damping characteristics of the soft rubber material reduce the transmission of motor vibration to the barrel 11, achieving vibration reduction and noise reduction; the low thermal conductivity of the soft rubber material also effectively blocks heat transfer between the heating plate 12 and the motor 3. In addition, the double-layer sealing structure on the mounting base 5, along with the design of the liquid accumulation chamber 56 and drainage channel, provides liquid leakage buffering and discharge functions, effectively protecting the safety of electrical components such as the motor 3. The food processing machine 100 provided by this utility model, including the mounting base 5, not only serves to install and fix the motor 3 but also provides sealing, heat insulation, and vibration reduction, thereby significantly improving the operational stability and sealing reliability of the food processing machine 100 while simplifying the assembly process and reducing manufacturing costs.

[0052] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
