Food processor with good protection effect

Abstract

The utility model discloses a food processing machine that has good protection effect, which comprises a base with a motor, a water tank, a lower water coupler, a lower power coupler, an upper water coupler, an upper power coupler, a handle, and a positioning ring. The lower water coupler is arranged directly below the handle, and the lower power coupler is arranged away from the lower water coupler in the circumferential direction. This arrangement ensures that the water supply is cut off before the power supply, effectively preventing the lower water coupler and the lower power coupler from being too close to each other. When the user lifts the crushing cup, the upper power coupler and the lower power coupler are separated first, and the lower water coupler and the upper water coupler are separated later. This prevents the water stains remaining in the upper water coupler from dripping into the lower power coupler, which prevents water from entering the base and the electrical components from being short-circuited or even damaged due to moisture. This effectively protects the electrical components.

Description

Technical Field

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

[0002] Existing food processors typically include a base with an internal motor and a detachable grinding cup mounted on the base. The grinding cup contains a grinding device connected to the motor. When using the food processor, the user places the ingredients into the grinding cup, and the grinding device rotates at high speed driven by the motor to process the ingredients. This traditional food processor requires the user to manually add water to the grinding chamber to process ingredients such as soy milk, which is very cumbersome. Therefore, to achieve automated processing and cleaning of ingredients, researchers have installed a water tank outside the machine, connected to the grinding cup via a water inlet pipe. When using the food processor, the user can use a water pump to pump water from the tank into the grinding cup, thus automating the food processing and significantly increasing the automation of the entire process. To achieve both power and water transmission, the applicant's earlier patent application CN202010958815.6 disclosed a food processing machine. This machine uses a lower electric coupler on the base and an upper electric coupler at the bottom of the grinding cup, coupled with the lower electric coupler, to transmit power. Simultaneously, a lower water coupler connected to a water tank is installed on the base, and an upper water coupler at the bottom of the grinding cup, connected to the grinding chamber and coupled with the lower water coupler, transmits water. However, in this model, the lower water coupler and the lower electric coupler are too close together and both are located directly below the handle, and the coupling length of the water coupler is much shorter than... When the user picks up the pulverizer cup by the handle, the water coupler disconnects first due to the coupling length of the electrical coupler. The disconnection of the water line is not as rapid as that of the electrical circuit; it is affected by the water flow itself and the mechanical structure of the water coupler. The water coupler requires a certain amount of time to close, and some water will remain in the upper water coupler. When the upper and lower water couplers disconnect, the water in the upper water coupler will drip downwards. Because the lower electrical coupler is too close to the lower water coupler, water droplets will drip directly into the lower electrical coupler, causing water to enter the base and potentially leading to moisture damage, short circuits, or even damage to electrical components, severely impacting the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a food processing machine with good protection, in order to solve the problem that in existing food processing machines with detachable crushing cups, the electrical coupler and water coupler are too close together, and when the water circuit and the electrical circuit are disconnected, the water remaining in the upper water coupler drips directly into the lower electrical coupler, causing the electrical components in the machine base to become damp and fail.

[0004] To achieve the above objectives, this utility model provides a food processing machine with good protective effect, including a base with a motor inside, a detachable grinding cup mounted on the base and having a grinding chamber inside, a grinding device connected to the motor in the grinding chamber, a water tank that can communicate with the grinding chamber in the base, a mounting platform on the top of the base, the grinding cup being detachably mounted on the mounting platform, a positioning ring with a mounting notch on the top surface of the mounting platform, a water coupling connected to the water tank at the mounting notch, an upper water coupling connected to the grinding chamber and coupled to the water coupling at the bottom of the grinding cup, a lower electric coupling inside the positioning ring, an upper electric coupling coupled to the lower electric coupling at the bottom of the grinding cup, a handle on the side wall of the grinding cup, the water coupling located directly below the handle, and the lower electric coupling positioned circumferentially away from the water coupling.

[0005] This application incorporates a water tank connected to the grinding chamber in the machine base, allowing users to directly supply water to the grinding cup during food processing. This eliminates the need for manual water supply and ensures more precise water injection, improving the accuracy of the food-to-water ratio and thus enhancing the texture and flavor of the processed food. The machine base also features a partially protruding lower water coupler connected to the water tank, and an upper water coupler at the bottom of the grinding cup that connects to the grinding chamber and couples with the lower water coupler. When the user places the grinding cup on the machine base, the upper and lower water couplers engage, opening the water path and allowing water from the tank to be pumped into the grinding chamber for cleaning and processing. Furthermore, the mounting platform features a positioning ring with an installation notch, ensuring precise and quick alignment when installing the grinding cup onto the platform, thus improving assembly efficiency. Furthermore, the side wall of the pulverizer cup is equipped with a handle, which allows users to lift the pulverizer cup by the handle, making it more convenient for users to operate and improving the user experience.

[0006] Having achieved the aforementioned functions, this application further positions the water coupling directly below the handle, while the electrical coupling is positioned circumferentially away from the water coupling. This ensures that when the user places the grinding cup on the base, the electrical coupling and the electrical coupling will first contact and connect, followed by the water coupling and the water coupling, achieving power-on before water-on. When the user removes the grinding cup from the base, because the water coupling and the electrical coupling are located directly below the handle, according to user habits, the side on the handle experiences greater force and will separate from the base first when the user lifts it. Therefore, when the user... When lifted, the upper and lower water couplers separate first, followed by the upper and lower electrical couplers, which are further from the handle. This ensures that water is cut off before power is cut off, effectively preventing situations where the lower water coupler and lower electrical coupler are too close together. In such cases, the upper and lower electrical couplers separate first, followed by the lower water coupler and upper water coupler, causing residual water in the upper water coupler to drip into the lower electrical coupler, potentially leading to water ingress into the base, short circuits, or even damage to electrical components. This design effectively protects electrical components, extends the equipment's lifespan, improves overall safety, and ensures worry-free operation. Furthermore, when the user holds the blender, they typically retract their arm naturally to lift it. During this process, the lower water coupler, located below the handle, quickly moves away from the base without passing through the lower electrical coupler on the base, thus preventing water droplets from falling onto it. Furthermore, in conjunction with the preferred embodiment of this application, a water tank is provided on the top of the base, and the pulverizing cups are arranged side by side on one side of the water tank. The water tank prevents the user from pushing the pulverizing cups toward the side with the lower electric coupler, and also prevents water droplets from falling on the lower electric coupler.

[0007] In a preferred embodiment of a food processing machine with good protective effect, the mounting platform is provided with a connector for motor drive, and the angle A between the line connecting the lower electric coupler and the connector and the line connecting the lower water coupler and the connector satisfies: 60°≤A≤180°.

[0008] By setting the angle A between the connection of the lower electrical coupler and the connector and the connection of the lower water coupler and the connector to satisfy 60°≤A≤180°, it can be ensured that the connection and disconnection sequence of the circuit and water circuit is reasonable during the installation and removal of the pulverizing cup. This avoids the situation where the angle between the connection of the lower electrical coupler and the connector and the connection of the lower water coupler and the connector is too small, which would cause the upper water coupler and the lower electrical coupler to separate as soon as the user lifts the pulverizing cup, resulting in residual water on the upper water coupler dripping directly onto the lower electrical coupler. This further optimizes the operation process, reduces the risk of misoperation, and improves the stability and reliability of equipment operation.

[0009] In a preferred embodiment of a food processing machine with good protective effect, the machine base is also provided with a micro switch, which is located at the mounting notch and is radially located outside the water coupling.

[0010] A microswitch is also installed on the base, ensuring that it is only triggered when the grinding cup is properly installed. This allows the motor and water pump to operate normally, effectively preventing unstable operation caused by the user starting the machine before the grinding cup is fully installed. The microswitch is located at the mounting notch and radially outside the water coupler, ensuring it is the last component to be triggered when the grinding cup is installed, guaranteeing all couplers are fully connected and further enhancing safety and ease of operation. Furthermore, when the grinding cup is lifted, the microswitch is the first to deactivate, immediately stopping the electrical components and preventing water from spraying out of the water coupler while the pump is still running.

[0011] In a preferred embodiment of a food processing machine with good protective effect, the mounting platform is provided with a connector that is connected to the motor drive, and the extension line of the connector and the drain coupler passes through a micro switch.

[0012] By extending the connection between the connector and the drain coupler through a microswitch, the microswitch is ensured to be located directly below the handle and outside the drain coupler. This ensures that the microswitch is triggered last during installation and disconnected first during disassembly, further improving the overall stability of the machine.

[0013] In a preferred embodiment of a food processing machine with good protective effect, a water-retaining groove is provided on the outer side of the water coupler.

[0014] By surrounding the water coupler with a water-retaining groove, when the cup body separates from the base, some of the liquid inside the base will still splash out under high pressure and then splash into the water-retaining groove, thus effectively collecting the liquid and preventing it from splashing everywhere. This effectively avoids the liquid splashing to other parts of the bottom of the crushing cup, especially the circuit parts such as the electrical coupler, which could cause the electrical components to become damp, insensitive, or even fail. This further improves the waterproof performance of the whole machine and ensures the stability of the whole machine operation.

[0015] In a preferred embodiment of a food processing machine with good protective effect, the crushing cup includes a cup body, a cup body support located below the cup body, and a heat insulation sleeve fixed below the cup body support. The heat insulation sleeve is partially concave to form a water-blocking groove, and the water inlet coupler passes through the heat insulation sleeve and extends into the water-blocking groove.

[0016] By recessing the heat insulation sleeve to form a water-blocking groove, the forming of the water-blocking groove is simplified. The heat insulation sleeve can also form a water-blocking groove while achieving heat insulation, serving two purposes in one piece. This eliminates the need for a separate structural component to form the water-blocking groove, which helps to simplify the overall machine structure, improve structural compactness, and reduce production costs.

[0017] In a preferred embodiment of a food processing machine with good protective effect, the mounting platform is provided with a connector that is connected to the motor drive, and the extension line of the connection between the connector and the water coupler passes through the water coupler.

[0018] By extending the connection between the connector and the drain coupler through the drain coupler, the drain coupler is made to be furthest from the drain coupler in the circumferential direction, and also furthest from the handle. This ensures that the electrical coupling is the last to disengage when the user lifts the pulverizing cup, further preventing water droplets from the upper water coupler from falling into the lower electrical coupler and further improving the waterproof effect.

[0019] In a preferred embodiment of a food processing machine with good protective effect, the lower electrical coupler has a first plug-in portion protruding from the mounting platform, and the lower water coupler has a second plug-in portion protruding from the mounting platform, wherein the height of the first plug-in portion is not lower than the height of the second plug-in portion.

[0020] By setting the height of the first plug-in part to be no less than the height of the second plug-in part, the lower power coupler and the upper power coupler are always in the plugged-in state before the lower water coupler and the upper water coupler are separated when the crushing cup is separated from the machine base, ensuring that the water is cut off before the power is cut off.

[0021] In a preferred embodiment of a food processing machine with good protective effect, the base includes a housing that houses the motor, the housing has an operating part that extends vertically upward and cooperates with the side wall of the water tank, and the handle is offset relative to the operating part.

[0022] By setting the handle to be offset relative to the operating part, it is more convenient and faster for users to place or pick up the crusher cup, which is more ergonomic and improves the user experience.

[0023] In a preferred embodiment of a food processing machine with good protective effect, the pulverizing cup includes a cup body, a heating plate located below the cup body, and a cup body support abutting below the heating plate. The cup body support is connected to the bottom of the cup body to clamp the heating plate between the cup body support and the cup body. A cup body shell is fitted on the outside of the cup body, and the top of the cup body shell is sealed to the outer wall of the cup body. A fixed support is fitted on the outside of the cup body support, and the fixed support is fixedly connected to the cup body support. The top of the fixed support is axially supported below the cup body shell and pushes the bottom of the cup body shell to abut against the top of the cup body support to clamp the cup body shell between the cup body support and the fixed support.

[0024] By encasing the outer shell of the cup body, a cavity is formed between the cup body and the outer shell. This cavity effectively reduces noise generated inside the cup during food processing, significantly minimizing noise transmission. It also improves the cup's heat retention, reducing heat loss. Furthermore, the top of the outer shell is sealed to the outer wall of the cup body, sealing the cavity and further enhancing noise reduction and heat retention. This also prevents water and dirt from entering the cavity through gaps between the outer shell and the side wall, ensuring the cleanliness of the cup body and its outer shell.

[0025] In addition, a fixed bracket is fitted on the outer side of the cup body support. The fixed bracket is fixedly connected to the cup body support, and the top of the fixed bracket axially supports the bottom of the cup body shell and pushes the bottom of the cup body shell to abut against the top of the cup body support, thus clamping the cup body shell between the cup body support and the fixed bracket. During the installation of the entire grinding cup, the heating plate is clamped between the cup body support and the cup body, and the fixed bracket is also fixedly connected to the cup body support. At the same time, the fixed bracket also supports the cup body shell, realizing that the installation benchmark of each component is the cup body support. That is, the installation benchmark is unified, which effectively avoids the superposition of multiple dimensional chains caused by too many installation benchmarks during the installation of the grinding cup. This would result in large tolerances after the entire grinding cup is assembled, which would lead to inaccurate alignment of the upper and lower connectors after the grinding cup is mated with the base, ultimately causing large vibrations and noises during food processing. This improves the accuracy of the grinding cup assembly, ensures the coaxiality of the entire grinding cup, and thus improves the accuracy of the alignment of the upper and lower connectors, and improves the stability during the transmission process.

[0034] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0035] 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.

[0036] like Figures 1 to 5 As shown, this utility model provides a food processing machine with good protective effect, including a base 2 with a motor inside, a detachable grinding cup 1 mounted on the base 2 and having a grinding chamber inside, a grinding device connected to the motor in the grinding chamber, and a water tank 3 that can communicate with the grinding chamber. Preferably, the grinding cup 1 and the water tank 3 are arranged side by side on the top of the base 2, and the grinding cup 1 is placed on the right side of the water tank 3, so that the user can easily pick up the grinding cup 1 with his right hand. The base 2 has a mounting platform on top, and the crushing cup 1 is detachably mounted on the mounting platform. The top surface of the mounting platform has a positioning ring 21 with a mounting notch 211. The mounting notch 211 has a water coupling 4 that communicates with the water tank 3. The bottom of the crushing cup 1 has an upper water coupling 9 that communicates with the crushing chamber and is coupled to the water coupling 4. The positioning ring 21 has a lower electric coupling 5. The bottom of the crushing cup 1 has an upper electric coupling 8 that is coupled to the lower electric coupling 5. The side wall of the crushing cup 1 has a handle 11. The water coupling 4 is located directly below the handle 11. The lower electric coupling 5 is positioned circumferentially away from the water coupling 4.

[0037] This application incorporates a water tank 3 connected to the grinding chamber in the base 2, allowing users to directly supply water to the grinding cup 1 during food processing. This eliminates the need for manual water supply and ensures more precise water injection into the grinding cup 1, improving the accuracy of the food-to-water ratio and thus enhancing the texture of the processed food. The base 2 also features a lower water coupler 4 that protrudes from the top surface of the mounting platform and connects to the water tank 3. The bottom of the grinding cup 1 has an upper water coupler 9 that connects to the grinding chamber and couples with the lower water coupler 4. When the user places the grinding cup 1 on the base 2, the upper water coupler 9 and the lower water coupler 4 engage, establishing a water flow. This allows water from the water tank 3 to be pumped into the grinding chamber for food cleaning and processing. Furthermore, the top surface of the mounting platform features a positioning ring 21 with an installation notch 211. The positioning ring 21 ensures precise and rapid alignment when the user installs the grinding cup 1 onto the mounting platform, improving assembly efficiency. Furthermore, the side wall of the grinding cup 1 is provided with a handle 11, which allows users to lift the grinding cup 1 by means of the handle 11, making it more convenient for users to operate and improving the user experience.

[0038] Meanwhile, the water coupler 4 is located directly below the handle 11, and the electrical coupler 5 is positioned circumferentially away from the water coupler 4. This ensures that when the user places the grinding cup 1 on the base 2, the electrical coupler 8 and the electrical coupler 5 will first contact and connect, followed by the water coupler 9 and the water coupler 4, achieving power connection before water connection. When the user removes the grinding cup 1 from the base 2, because the water coupler 9 and the water coupler 4 are located directly below the handle 11, according to user habits, the side on the handle 11 experiences greater force and will separate from the base 2 first when the user lifts it. Therefore, when the user lifts it, the water coupler 9 will... The water coupler 9 separates from the lower coupling 4 first, followed by the upper coupling 8 and lower coupling 5, which are further away from the handle 11. This ensures that the water supply is cut off before the power is cut off, effectively preventing the water coupler 4 and lower coupling 5 from being too close together. This avoids the situation where, when the user lifts the pulverizing cup 1, the upper coupling 8 and lower coupling 5 separate first, followed by the water coupler 4 and upper coupling 9, causing residual water in the upper coupling 9 to drip into the lower coupling 5, resulting in water entering the base 2 and causing electrical components to become damp, short-circuit, or even damaged. This helps to effectively protect the electrical components, extend the service life of the equipment, improve overall safety, and ensure worry-free operation for the user. Furthermore, when the user holds the pulverizing cup 1, they usually naturally retract their arm to lift it. During this process, the water coupler 4, located below the handle, can quickly move away from the base 2 without passing through the lower coupling 5 on the base, thus preventing water droplets from falling onto the lower coupling 5. Furthermore, in the preferred embodiment of this application, a water tank 3 is provided on the top of the base 2, and the pulverizing cups 1 are arranged side by side on one side of the water tank. The water tank 3 prevents the user from pushing the pulverizing cups 1 toward the side with the lower electric coupler 5, and also prevents water droplets from falling on the lower electric coupler 5.

[0039] As a preferred embodiment of this application, such as Figure 5 As shown, the mounting platform is equipped with a connector 6 that is connected to the motor drive. The angle A between the line connecting the power coupler 5 and the connector 6 and the line connecting the water coupler 4 and the connector 6 satisfies: 60°≤A≤180°.

[0040] By setting the angle A between the connection of the lower electrical coupler 5 and connector 6 and the connection of the lower water coupler 4 and connector 6 to satisfy 60°≤A≤180°, it can be ensured that the connection and disconnection sequence of the circuit and water circuit is reasonable during the installation and removal of the crushing cup 1. This avoids the situation where the angle between the connection of the lower electrical coupler 5 and connector 6 and the connection of the lower water coupler 4 and connector 6 is too small, which would cause the upper water coupler 9 to separate from the lower water coupler 4 when the user lifts the crushing cup 1, and the upper electrical coupler 8 to separate from the lower electrical coupler 5, resulting in residual water on the upper water coupler 9 dripping directly onto the lower electrical coupler 5. This further optimizes the operation process, reduces the risk of misoperation, and improves the stability and reliability of equipment operation.

[0041] As a preferred embodiment of this application, such as Figure 3 As shown, the base 2 is also provided with a micro switch 7, which is located at the mounting notch 211 and is radially located outside the water coupling 4.

[0042] By also providing a microswitch 7 on the base 2, the microswitch 7 can only be triggered when the grinding cup 1 is installed in place, ensuring that electrical components such as the motor and water pump can operate normally. This effectively prevents unstable transmission caused by the user starting the machine before the grinding cup 1 is properly installed. Furthermore, the microswitch 7 is located at the mounting notch 211 and radially outside the water coupling 4, ensuring that it is triggered last when the user installs the grinding cup 1 onto the base 2, guaranteeing that all couplings are fully connected. This further enhances the safety and ease of operation of the equipment. Simultaneously, when the user lifts the grinding cup 1, the microswitch 7 is the first to disengage, ensuring that the electrical components immediately stop working and preventing water from spraying outwards from the water coupling 4 while the grinding cup 1 is being lifted.

[0043] Furthermore, such as Figure 3 , Figure 5 As shown, the mounting platform is equipped with a connector 6 that is connected to the motor drive, and the extension line of the connection between the connector 6 and the drain coupler 4 passes through a micro switch 7.

[0044] By extending the connection between connector 6 and drain coupler 4 through micro switch 7, it is ensured that micro switch 7 is located directly below handle 11 and outside drain coupler 4, so that micro switch 7 is triggered last during installation of pulverizing cup 1 and disconnected first during separation, thereby further improving the stability of the whole machine operation.

[0045] As a preferred embodiment of this application, such as Figure 4 As shown, a water-blocking groove 121 is provided around the outside of the water-upper coupler 9.

[0046] By providing a water-blocking groove 121 around the outside of the water coupler 9, when the cup body is separated from the base 2, some of the liquid inside the base 2 will still splash out under greater pressure and then splash into the water-blocking groove 121, thus being effectively collected. This prevents the liquid from splashing everywhere and effectively avoids the liquid splashing to other positions at the bottom of the crushing cup 1, especially the circuit positions such as the electrical coupler, which could cause the electrical components to become damp, insensitive, or even fail. This further improves the waterproof performance of the whole machine and ensures the stability of the whole machine operation.

[0047] It should be noted that this application does not specifically limit the molding of the water-retaining groove 121. As one preferred embodiment of this application, such as... Figure 4As shown, the pulverizing cup 1 includes a cup body, a cup body support located below the cup body, and a heat insulation sleeve 12 fixed below the cup body support. The heat insulation sleeve 12 is partially concave to form a water-blocking groove 121. The water inlet coupler 9 passes through the heat insulation sleeve 12 and extends into the water-blocking groove 121.

[0048] By recessing part of the heat insulation sleeve 12 to form a water baffle 121, the forming of the water baffle 121 is simplified. The heat insulation sleeve 12 can form a water baffle 121 while achieving heat insulation. It serves two purposes in one piece, eliminating the need for a separate structural component to form the water baffle 121. This helps to simplify the overall structural components, improve the structural compactness, and reduce production costs.

[0049] As a preferred embodiment of this application, such as Figure 5 As shown, the mounting platform is equipped with a connector 6 that is connected to the motor drive, and the extension line of the connection between the connector 6 and the drain coupler 4 passes through the drain coupler 5.

[0050] By setting the extension line of the connection between connector 6 and the water coupler 4 to pass through the lower electrical coupler 5, the distance between the lower electrical coupler 5 and the water coupler 4 in the circumferential direction is maximized, and the distance between the lower electrical coupler 5 and the handle 11 is also maximized. This ensures that when the user lifts the pulverizing cup 1, the electrical coupling is the last to disengage, which can further prevent water droplets in the upper water coupler 9 from falling into the lower electrical coupler 5, and further improve the waterproof effect.

[0051] In a preferred embodiment of this application, the power coupler 5 is provided with a first plug portion protruding from the mounting platform, and the water coupler 4 is provided with a second plug portion protruding from the mounting platform. The height of the first plug portion is not lower than the height of the second plug portion.

[0052] By setting the height of the first plug-in part to be no less than the height of the second plug-in part, when the crushing cup 1 is separated from the base 2, before the water coupler 4 and the water coupler 9 are separated, the power coupler 5 and the power coupler 8 are always in the plug-in state, ensuring that the water is cut off before the power is cut off.

[0053] As a preferred embodiment of this application, such as Figure 1 , Figure 2 As shown, the base 2 includes a housing that houses the motor. The housing has an operating part 22 that extends vertically upward and cooperates with the side wall of the water tank 3. The handle 11 is offset relative to the operating part 22.

[0054] By setting the handle 11 to be offset relative to the operating part 22, it is more convenient and faster for users to place or pick up the crushing cup 1, which is more ergonomic and improves the user experience.

[0055] As a preferred embodiment of this application, such as Figure 1As shown, the pulverizing cup 1 includes a cup body, a heating plate located below the cup body, and a cup body support abutting below the heating plate. The cup body support is connected to the bottom of the cup body to clamp the heating plate between the cup body support and the cup body. A cup body shell is fitted on the outside of the cup body, and the top of the cup body shell is sealed to the outer wall of the cup body. A fixed bracket is fitted on the outside of the cup body support, and the fixed bracket is fixedly connected to the cup body support. The top of the fixed bracket is axially supported below the cup body shell and pushes the bottom of the cup body shell to abut against the top of the cup body support, so as to clamp the cup body shell between the cup body support and the fixed bracket.

[0056] By encasing the outer shell of the cup body, a cavity is formed between the cup body and the outer shell. This cavity effectively reduces noise generated inside the cup during food processing, significantly minimizing noise transmission. It also improves the cup's heat retention, reducing heat loss. Furthermore, the top of the outer shell is sealed to the outer wall of the cup body, sealing the cavity and further enhancing noise reduction and heat retention. This also prevents water and dirt from entering the cavity through gaps between the outer shell and the side wall, ensuring the cleanliness of the cup body and its outer shell.

[0057] In addition, a fixed bracket is fitted on the outer side of the cup body support. The fixed bracket is fixedly connected to the cup body support, and the top of the fixed bracket axially supports the bottom of the cup body shell and pushes the bottom of the cup body shell to abut against the top of the cup body support, so as to clamp the cup body shell between the cup body support and the fixed bracket. During the installation of the entire grinding cup 1, the heating plate is clamped between the cup body support and the cup body, and the fixed bracket is also fixedly connected to the cup body support. At the same time, the fixed bracket also supports the cup body shell, so that the installation reference of each component is the cup body support. That is, the installation reference is unified, which effectively avoids the superposition of multiple dimensional chains due to too many installation references during the installation of the grinding cup 1. This would result in large tolerances after the entire grinding cup 1 is assembled, which would lead to inaccurate alignment of the upper and lower connectors 6 after the grinding cup 1 is connected to the base 2. Ultimately, this would lead to large vibration and noise during food processing. This improves the assembly accuracy of the grinding cup 1, ensures the coaxiality of the entire grinding cup 1, and improves the alignment accuracy of the upper and lower connectors 6, thereby improving the stability during the transmission process.

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.
