Description

Technical Field

[0001] This utility model relates to household appliances, and in particular to a sealing structure and a food processor. Background Technology

[0002] With economic development and improved living standards, people have increasingly higher demands for quality of life, making food processors a necessity for most households. However, in current technology, the sealing structure of the safety port on food processors is not very effective, allowing splashes of water from washing the food processor to enter its interior. This can cause short circuits in the internal electronic components and even lead to electric shocks, seriously threatening the user's life and property safety. Utility Model Content

[0003] Therefore, it is necessary to provide a sealing structure and a food processor to address the problem of insufficient sealing of the safety port in food processors.

[0004] A sealing structure includes: a base assembly having a drain hole; a connecting bracket disposed on the base assembly and having a limiting hole; a connecting rod assembly having one end passing through the drain hole and the other end passing through the limiting hole, the connecting rod assembly being movable relative to the base assembly; and a sealing assembly disposed on the connecting rod assembly, the sealing assembly being able to open or close the drain hole when the connecting rod assembly moves.

[0005] The above-disclosed sealing structure, in terms of drainage, precisely controls the opening and closing of the drain hole through the coordinated action of the connecting rod assembly, base assembly, and connecting bracket. When drainage is needed, the moving connecting rod assembly drives the sealing assembly to open the drain hole, achieving efficient drainage; after drainage, it can be quickly closed, effectively preventing residual water and keeping the inside of the food processor clean. Simultaneously, the sealing assembly and drain hole fit tightly together, forming a reliable seal and preventing water penetration. This not only protects the electrical components inside the food processor from damage due to moisture and short circuits, extending the lifespan of the food processor, but also ensures a dry and clean operating environment, reducing safety hazards caused by leakage. The components of this sealing structure are rationally arranged and have a simple structure, making it easy to install and maintain. In the manufacturing process, it reduces process difficulty and cost; in daily use, it facilitates cleaning and troubleshooting, improving the user experience.

[0006] In one embodiment, the sealing assembly includes a first seal and a second seal. The first seal is disposed on the connecting rod assembly, and the second seal is disposed on the connecting rod assembly. The first seal can open or close the drain hole and the drain side groove, and the second seal is used to seal the gap between the base assembly and the connecting rod assembly. By placing the first seal in a first slot of the connecting rod assembly and the second seal in a second slot of the connecting rod assembly, the first and second slots provide precise installation positions for the first and second seals. This slot-type design allows the seals to be accurately placed on the connecting rod assembly, ensuring their fixed position in space. The slots effectively prevent the seals from shifting during equipment operation, thus ensuring that the seals are always in the correct working position and effectively sealing the areas that need to be sealed. Secondly, it allows the sealing assembly to better cooperate with the movement of the connecting rod assembly to achieve the sealing purpose of the food processor. The first seal is used to seal the drain hole and drain side channel during food processing, preventing cleaning liquid from entering the interior of the food processor body. This effectively prevents the cleaning liquid from contacting electronic components such as the motor and control circuit board, creating a dry and safe working environment for these important internal parts of the food processor. The second seal is used to seal the mating gap between the connecting rod assembly and the mating hole of the base assembly, further enhancing the sealing effect of the flexible sealing structure and ensuring the stability and dryness of the entire internal environment of the food processor.

[0007] In one embodiment, the first seal includes a first sealing block and a flexible sealing sleeve. The connecting rod assembly has a first groove, the first sealing block is disposed on the connecting rod assembly and located in the first groove, and the flexible sealing sleeve is disposed on the first sealing block. By placing the first sealing block in the first groove on the connecting rod assembly and then placing the flexible sealing sleeve on the first sealing block, the first groove provides precise positioning for the first sealing block. The shape and size of the groove match the first sealing block, allowing the first sealing block to be accurately placed at a predetermined position on the connecting rod assembly. This precise positioning ensures that the first seal is fixed in position on the connecting rod assembly, providing a stable foundation for subsequent sealing operations. Secondly, the flexible sealing sleeve has good flexibility and fit. During the process of sealing cleaning water, it can fit tightly around the drain hole and drain side groove of the base assembly, effectively filling the tiny gap between the first seal and the base assembly, forming a continuous sealing barrier, thereby preventing cleaning water from leaking into the interior of the food processor. At the same time, the flexible sealing sleeve can expand or contract accordingly, always maintaining a sealed state. In the event of vibration or component displacement, it can also elastically deform within a certain range to maintain close contact with the base assembly, ensuring that cleaning water does not penetrate into the interior due to these factors, thus ensuring a dry internal environment for the food processor.

[0008] In one embodiment, the second seal includes a second sealing block and a sealing sleeve. The connecting rod assembly has a second groove, the second sealing block is disposed on the connecting rod assembly and located in the second groove, and the sealing sleeve is disposed on the second sealing block. By placing the second sealing block in the second groove of the connecting rod assembly, a precise installation position is provided for the second sealing block. By placing the sealing sleeve on the second sealing block, the mating gap between the connecting rod assembly and the base assembly can be sealed, preventing washing water from entering the gap space and filling the entire sealed space above the drain device. This prevents the washing water from being smoothly and quickly discharged when the drain hole and drain side groove are opened, further enhancing the sealing performance of the flexible sealing structure.

[0009] In one embodiment, the linkage assembly includes a first linkage body and a first spring. One end of the first linkage body passes through the limiting hole, and the other end passes through the drain hole and mating hole of the base assembly. The first spring is sandwiched between the first linkage body and the connecting bracket. The first linkage body has a first slot and a second slot. The sealing assembly is disposed on the first linkage body and located at the first slot and the second slot. When the first linkage body moves, the first spring can be compressed or stretched. When the first spring is compressed, the sealing assembly separates from the base assembly, and the drain hole and the drain side groove open. When the first spring is stretched, the sealing assembly abuts against the base assembly, and the drain hole and the drain side groove close. By simultaneously passing the first linkage body through the limiting hole of the connecting bracket and the drain hole and mating hole of the base assembly, the position of the first linkage body in the entire sealing structure can be accurately determined, ensuring the relative positional accuracy between the first linkage assembly and the base assembly, laying the foundation for the normal operation of the entire sealing structure. A first spring is clamped between the first connecting rod body and the connecting bracket, while a sealing component is positioned in the first and second slots of the first connecting rod body. This allows the first connecting rod body to drive the sealing component to open and close the drain hole and drain side channel. When the drain hole and drain side channel need to be opened, the weight of the food processor overcomes the spring force, causing the first connecting rod body to move, thereby moving the sealing component away from the sealing position of the drain hole and drain side channel, achieving the opening action. When the food processor is lifted, the spring force of the first spring causes the first connecting rod body to return to its original position, closing the drain hole and drain side channel. This automatic reset function simplifies the sealing operation process and reduces the need for manual intervention. By passing the first connecting rod through the limiting hole of the connecting bracket and fitting the first spring onto the first connecting rod and clamping it between the first connecting rod and the connecting bracket, precise guidance is provided for the movement of the first connecting rod. The shape and size of the limiting hole are adapted to the first connecting rod, ensuring that the first connecting rod can only move in a specific direction and range. This guiding effect ensures that the movement trajectory of the first connecting rod during equipment operation is predictable and stable. The second connecting rod is then placed on the first connecting rod and passes through the mating hole. The first spring pushes or pulls the first connecting rod, which in turn drives the second connecting rod to move. This allows the sealing components located in the first and second slots of the second connecting rod to open and close the drain hole and the drain side groove. The elasticity of the first spring ensures that the sealing components fit tightly against the drain device, providing sufficient sealing pressure. Combined with the flexibility of the sealing structure itself, this effectively enhances the sealing effect and ensures the safe use of the food processor.

[0010] In one embodiment, the base assembly includes a first base, mounting pins, and a water-blocking component. Multiple mounting pins are disposed on the first base, and the connecting bracket is disposed on the multiple mounting pins. The water-blocking component is disposed on the first base, which has drainage holes. The water-blocking component cooperates with the first base to form a drainage side groove, and the water-blocking component has mating holes. By disposing of multiple mounting pins on the first base, the mounting pins serve as connecting components between the connecting bracket and the first base, increasing the stability of the connection. When the connecting bracket is installed on the mounting pins, the mounting pins can withstand a certain force. During equipment operation, the connecting bracket may be subjected to displacement tendencies due to the movement of the linkage assembly, external vibrations, or other forces. The mounting pins can effectively resist these forces, preventing the connecting bracket from loosening or shifting relative to the base. By placing the water-blocking component on the base, most of the water during washing is blocked at the drain hole, preventing washing water from entering the food processor's interior. Simultaneously, the shape and structure of the drain side groove formed by the water-blocking component and the base assembly helps guide the washing water towards the drain hole. It concentrates the washing water accumulated on the base, directing it along a preset path to the drain hole, improving drainage efficiency and preventing washing water from accumulating in the first base. The water-blocking component has mating holes that allow the connecting rod assembly to move within a defined space, ensuring reliable sealing. By placing the water-blocking base on the first base and then placing the baffle on the water-blocking base, the water-blocking base effectively blocks liquid from flowing directly into the food processor during washing, preventing washing liquid from flowing directly into the food processor. The baffle, placed on the water-blocking base, further enhances the waterproof capability, greatly preventing washing water from rushing in and reducing splashing, effectively forming a double-layer protection system. By rationally setting the position and shape of the water-blocking base and baffle, the drainage path can be optimized, effectively ensuring the dryness of the food processor's internal environment and improving the overall service life and reliability of the food processor. The stop block has a mating hole that limits the range of motion of the connecting rod assembly, ensuring that the sealing assembly can stably perform its sealing function for the food processor.

[0011] In one embodiment, the linkage assembly includes a second linkage body and a second spring. The sealing assembly is disposed on the second linkage body, and the second spring is sandwiched between the connecting bracket and the second linkage body. When the second linkage body moves, the second spring can be compressed or stretched. When the second spring is compressed, the sealing assembly separates from the base assembly, and the drain hole opens. When the second spring is stretched, the sealing assembly abuts against the base assembly, and the drain hole closes. By placing the second spring between the connecting bracket and the second linkage body, when the food processor needs to be cleaned, the spring force of the second spring will push the second linkage body downward, closing the drain hole to prevent cleaning water from entering the interior of the food processor, ensuring a dry internal circuit environment. When the food processor is placed on a table, the second spring is compressed between the connecting bracket and the second linkage body. At this time, the second linkage body rises closer to the mating hole, which also drives the sealing assembly to move upward, opening the drain hole and draining the internal water, keeping the inside of the food processor clean. The design of the second spring allows the sealing assembly to easily switch between open and closed states, and ensures that the drain hole remains closed when no external force is applied, preventing accidental liquid leakage. The second linkage body includes a first push rod assembly, an intermediate connecting rod, and a second push rod assembly. The first push rod assembly, the intermediate connecting rod, and the second push rod assembly are connected sequentially. The connecting bracket has the limiting hole. The first push rod assembly passes through the limiting hole of the connecting bracket, and the second push rod assembly passes through the mating hole of the base assembly. The sealing assembly is disposed on the second push rod assembly. By inserting the first push rod assembly through the connecting bracket and positioning it at the limiting hole, the limiting hole provides a clear movement boundary for the first linkage assembly. When the first linkage assembly is inserted through the connecting bracket and positioned at the limiting hole, its movement trajectory is restricted within the range specified by the limiting hole. This restriction prevents excessive displacement or deviation from the predetermined movement path of the first linkage assembly during operation. This is crucial for ensuring precise fit between the first linkage assembly and the base assembly, avoiding malfunction of the entire device due to positional deviation of the first linkage assembly. The second push rod assembly is mounted on the first push rod assembly, passing through the base assembly and located at the mating hole. This mating hole provides precise positioning and guidance for the second push rod assembly. Combined with the sealing assembly on the second push rod assembly, this enables precise opening and closing of the drainage hole. The position of the mating hole also determines the relative position of the second push rod assembly within the base assembly, ensuring the rational spatial layout of the entire drainage control mechanism. The intermediate connecting rod is mounted on the second push rod assembly, increasing its structural strength and ensuring stability under various complex stress conditions, reducing the possibility of structural loosening or failure.

[0012] In one embodiment, the first push rod assembly includes a first connecting rod and a first push block. The first connecting rod passes through the limiting hole of the connecting bracket. The two ends of the first push block are respectively connected to the first connecting rod and the intermediate connecting rod. The second spring is sleeved on the first connecting rod and sandwiched between the connecting bracket and the first push block. By passing the first connecting rod through the connecting bracket and positioning it at the limiting hole, the limiting hole provides precise motion guidance for the first connecting rod, enabling it to move in a specific direction. The first push block is positioned on the first connecting rod, and the second spring is also positioned on the first connecting rod and sandwiched between the connecting bracket and the first push block. The presence of the second spring enables the first connecting rod to have an automatic reset function. When an external force causes the first connecting rod to move, causing the first push block to compress the second spring, the second spring is compressed and stores elastic potential energy. Once the external force disappears, the elastic potential energy of the second spring is released, pushing the first push block and thus causing the first connecting rod to return to its initial position, thereby opening and closing the drain hole and ensuring the continuity and stability of the sealing structure. The second push rod assembly includes a second connecting rod and a second push block. The second connecting rod is disposed on the intermediate connecting rod and on the first push rod assembly. The second connecting rod passes through the base assembly and is located at the mating hole. The second push block is disposed on the second connecting rod, and the sealing ring is disposed on the second connecting rod and / or the second push block. By disposing of the intermediate connecting rod on the second connecting rod, the structural strength of the second connecting rod can be improved, ensuring that the second connecting rod can work normally and stably. Disposing of the second connecting rod on the first push rod assembly will play a role in force transmission. When the first push rod assembly is subjected to the force of the second spring, it will simultaneously drive the second connecting rod to move. Since the second connecting rod is located at the mating hole of the base assembly, and the sealing ring and the second push block are disposed on the second connecting rod, the force of the first push rod assembly can simultaneously drive the sealing ring and the second push block to move. Combined with the mating hole, the opening and closing of the drain hole can be precisely controlled. When the second spring is stretched, the second push block will press the sealing ring against the drain hole, at which time the drain hole is closed. When the second spring is compressed, the second connecting rod will drive the sealing ring upward, at which time the drain hole is opened.

[0013] In one embodiment, the base assembly includes a second base, mating pins, and a drainage assembly. Multiple mating pins are disposed on the second base. The connecting bracket is disposed on the multiple mating pins, and the drainage assembly is disposed on the second base, having a drainage hole and a mating hole. By disposing of multiple mating pins on the second base, a mounting position is provided for the connecting bracket. Through the engagement with the mating pins, the connecting bracket can be accurately placed in the designed position, ensuring that the connecting rod assembly can be accurately aligned at the mating hole, guaranteeing the normal operation of the connecting rod assembly. Simultaneously, the multiple mating pins provide a stable mounting base for the connecting bracket. When the connecting bracket is installed on the multiple mating pins, a strong connection is formed between the connecting bracket and the second base through an appropriate connection method, further ensuring the stable operation of the connecting rod assembly under the action of the second spring. The drainage assembly is disposed on the second base and has a drainage hole and a mating hole. The drainage assembly can engage with the connecting rod assembly through the mating hole. When the connecting rod assembly is used to control drainage or waterproofing, one end of the connecting rod can be inserted into the mating hole, thus accurately controlling the opening and closing of the drainage hole when the connecting rod moves. The drainage assembly includes connecting blocks and cylindrical blocks. Multiple connecting blocks are spaced apart on the base and arranged in a ring. Cylindrical blocks are disposed on the connecting blocks and have mating holes. The multiple connecting blocks, cylindrical blocks, and the base together form multiple drainage holes. By arranging multiple connecting blocks along the circumference of the base and placing cylindrical blocks on them, multiple drainage holes are formed. First, the presence of multiple drainage holes significantly improves drainage efficiency. In equipment such as food processors, when internal liquid needs to be drained, the liquid can flow out simultaneously through multiple drainage holes. Compared to a single drainage hole, multiple drainage holes can increase the cross-sectional area of ​​drainage. Second, multiple drainage holes help achieve uniform drainage. If there is only one drainage hole, liquid tends to concentrate in that hole, potentially leading to uneven liquid distribution inside the equipment, making it difficult to drain liquid from certain areas. Multiple drainage holes can guide liquid to flow out from different directions, ensuring the cleanliness and dryness of the food processor's interior. The mating holes provided by the cylindrical block provide a position for the mating and movement of the connecting rod assembly, ensuring that the connecting rod assembly can move along the direction set by the mating holes.

[0014] In one embodiment, the connecting bracket includes a bracket and connecting sleeves. Multiple connecting sleeves are disposed on both sides of the bracket, and the bracket is connected to the base assembly via these connecting sleeves. The bracket is provided with the limiting hole. By distributing multiple connecting sleeves on both sides of the bracket, and then connecting the bracket to the base assembly using these connecting sleeves, this dual-sided distribution structure allows for a more balanced connection between the bracket and the base assembly. Under stress, the connecting sleeves on both sides can evenly distribute the weight of the bracket and other external forces, avoiding the uneven stress that may occur with a single-sided connection. The connecting sleeves on both sides can work together to keep the bracket stable, reducing the possibility of swaying and tilting. Simultaneously, the connecting sleeves serve as connection points, and the presence of multiple connection points increases the reliability of the connection. Compared to a single-point connection, a multi-point connection can distribute the stress at the connection points. The supporting force of the base assembly on the bracket is transmitted through multiple connecting sleeves, reducing the pressure on each connection point, thus making the connection more robust and better able to withstand various complex external forces.

[0015] In one embodiment, the linkage assembly includes a linkage body and a solenoid valve assembly. A sealing assembly is disposed on the linkage body. The solenoid valve assembly controls the movement of the linkage body and opens or closes the drain hole and the drain side channel through the sealing assembly. The opening and closing of the drain hole is achieved by controlling the movement of the linkage body using the solenoid valve assembly. Due to the control of the electrical signal, the solenoid valve assembly can precisely control the movement of the linkage body, thereby driving the sealing assembly to move. During drainage operation, when it is necessary to open or close the drain hole and drain side channel, the solenoid valve assembly receives an opening signal and drives the linkage body to a specific position. The solenoid valve assembly itself has a relatively stable structure. Its internal electromagnetic drive principle allows it to work stably for a relatively long time. When controlling the movement of the linkage body, as long as the power supply and signal transmission are normal, the solenoid valve can accurately complete the task. Compared with traditional mechanical control methods, this reduces problems such as wear and loosening of mechanical parts.

[0016] In one embodiment, the linkage assembly includes a linkage body and a magnet. The sealing assembly is disposed on the linkage body. The magnet controls the movement of the linkage body and opens or closes the drain hole and the drain side channel through the sealing assembly. By using a rationally designed magnet layout and magnetic field strength to control the movement of the linkage body, the sealing assembly is moved, thereby opening and closing the drain hole and the drain side channel. Compared with mechanical connections, magnets do not cause component damage due to friction between mechanical parts. Therefore, they can guide the linkage body to move stably along a specific path, thereby achieving precise opening and closing of the drain hole and the drain side channel. The movement of the linkage body will not be hindered due to wear or loosening of mechanical parts, thus improving the reliability of the sealing structure of the entire food processor.

[0017] The second aspect of this application discloses a food processor, which includes: the aforementioned sealing structure; and a food processor main unit, wherein the sealing structure is disposed on the food processor main unit.

[0018] The second aspect disclosed above discloses a food processor. By incorporating a sealing structure on the main unit of the food processor, it is possible for washing water to splash in from the bottom during the cleaning process. The sealing structure, through its sealing material, can tightly adhere to the drain hole. Utilizing its good flexibility and sealing properties, it can effectively prevent washing water from penetrating into the main unit, avoiding contact with sensitive electronic components such as the motor and circuit board, preventing component damage, and extending the service life of the food processor. More importantly, it can prevent electric shock to users while using the food processor, ensuring user safety and enhancing the market competitiveness of the food processor.

[0039] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] 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.

[0041] The sealing structure and food processing machine of some embodiments of the present invention are described below with reference to the accompanying drawings.

[0042] Example 1

[0043] like Figures 1 to 15As shown, this embodiment discloses a sealing structure, including: a base assembly 1, the base assembly 1 having a drain hole 101; a connecting bracket 2, the connecting bracket 2 being disposed on the base assembly 1, the connecting bracket 2 having a limiting hole 201; a connecting rod assembly 3, one end of the connecting rod assembly 3 passing through the drain hole 101, the other end of the connecting rod assembly 3 passing through the limiting hole 201, the connecting rod assembly 3 being able to move relative to the base assembly 1; and a sealing assembly 4, the sealing assembly 4 being disposed on the connecting rod assembly 3, the connecting rod assembly 3 being able to drive the sealing assembly 4 to open or close the drain hole 101 when it moves.

[0044] This application discloses a sealing structure. In terms of drainage, the opening and closing state of the drain hole 101 can be precisely controlled through the coordinated action of the connecting rod assembly 3, the base assembly 1, and the connecting bracket 2. When drainage is needed, the connecting rod assembly 3 moves to drive the sealing assembly 4 to open the drain hole 101, achieving efficient drainage. After drainage, it can be quickly closed, effectively preventing residual water and keeping the inside of the food processor clean. Simultaneously, the sealing assembly 4 and the drain hole 101 fit tightly together, forming a reliable seal and preventing water penetration. This not only protects the electrical components inside the food processor from damage due to moisture and short circuits, extending the service life of the food processor, but also ensures a dry and clean operating environment, reducing safety hazards caused by leakage. The components of this sealing structure are rationally arranged and have a simple structure, making it easy to install and maintain. In the manufacturing process, it reduces process difficulty and cost; in daily use, it facilitates cleaning and troubleshooting, improving the user experience.

[0045] like Figures 1 to 9As shown, in addition to the features of the above embodiments, this embodiment further defines: the sealing assembly 4 includes a first sealing element 41 and a second sealing element 42. The first sealing element 41 is disposed on the connecting rod assembly 3, and the second sealing element 42 is disposed on the connecting rod assembly 3. The first sealing element 41 can open or close the drain hole 101 and the drain side groove 102, and the second sealing element 42 is used to seal the gap between the base assembly 1 and the connecting rod assembly 3. By disposing the first sealing element 41 at the first slot 301 of the connecting rod assembly 3 and the second sealing element 42 at the second slot 302 of the connecting rod assembly 3, the first slot 301 and the second slot 302 provide precise installation positions for the first sealing element 41 and the second sealing element 42. This slot-type design allows the sealing element to be accurately placed on the connecting rod assembly 3, ensuring its fixed position in space. The slots can effectively prevent the sealing element from shifting during equipment operation, thereby ensuring that the sealing element is always in the correct working position and effectively sealing the area that needs to be sealed. Secondly, it allows the sealing components to better cooperate with the movement of the connecting rod assembly 3, achieving the sealing purpose of the food processor. The first seal 41 is used to seal the drain hole 101 and the drain side groove 102 during cleaning of the food processor, preventing cleaning liquid from entering the interior of the food processor body from the drain hole 101 and the drain side groove 102, effectively preventing the cleaning liquid from contacting electronic components such as motors and control circuit boards, creating a dry and safe working environment for these important components inside the food processor. The second seal 42 is used to seal the mating gap of the connecting rod assembly 3 in the mating hole 103 of the base assembly 1, further enhancing the sealing effect of the flexible sealing structure and ensuring the stability and dryness of the entire internal environment of the food processor.

[0046] like Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first sealing element 41 includes a first sealing block 411 and a flexible sealing sleeve 412; the connecting rod assembly 3 is provided with a first slot 301; the first sealing block 411 is disposed on the connecting rod assembly 3 and located at the first slot 301; and the flexible sealing sleeve 412 is disposed on the first sealing block 411. By disposing the first sealing block 411 at the first slot 301 on the connecting rod assembly 3, and then disposing the flexible sealing sleeve 412 on the first sealing block 411, the first slot 301 provides precise positioning for the first sealing block 411. The shape and size of the slot match the first sealing block 411, allowing the first sealing block 411 to be accurately placed at a predetermined position on the connecting rod assembly 3. This precise positioning ensures that the position of the first sealing element 41 on the connecting rod assembly 3 is fixed, providing a stable foundation for subsequent sealing operations. Secondly, the flexible sealing sleeve 412 has good flexibility and fit. During the process of sealing cleaning water, it can fit tightly around the drain hole 101 and drain side groove 102 of the base assembly 1, effectively filling the tiny gap between the first seal 41 and the base assembly 1, forming a continuous sealing barrier, thereby preventing cleaning water from leaking into the interior of the food processor. At the same time, the flexible sealing sleeve 412 can expand or contract accordingly, always maintaining a sealed state. In the event of vibration or component displacement, it can also elastically deform within a certain range to maintain close contact with the base assembly 1, ensuring that cleaning water will not penetrate into the interior due to these factors, and ensuring that the internal environment of the food processor is dry.

[0047] like Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second sealing member 42 includes a second sealing block 421 and a sealing sleeve 422; the connecting rod assembly 3 is provided with a second slot 302; the second sealing block 421 is disposed on the connecting rod assembly 3 and located at the second slot 302; and the sealing sleeve 422 is disposed on the second sealing block 421. By disposing the second sealing block 421 at the second slot 302 of the connecting rod assembly 3, a precise installation position for the second sealing block 421 is provided. By disposing the sealing sleeve 422 on the second sealing block 421, the mating gap between the connecting rod assembly 3 and the base assembly 1 can be sealed, preventing washing water from entering the gap space and filling the entire sealed space above the drain device. This prevents the washing water from being discharged smoothly and quickly when the drain hole 101 and the drain side groove 102 are opened, thereby further increasing the sealing performance of the sealing structure.

[0048] like Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines: the connecting rod assembly 3 includes a first connecting rod body 31 and a first spring 32. One end of the first connecting rod body 31 passes through the limiting hole 201, and the other end of the first connecting rod body 31 passes through the drain hole 101 and the mating hole 103 provided in the base assembly 1. The first spring 32 is sandwiched between the first connecting rod body 31 and the connecting bracket 2. The first connecting rod body 31 is provided with a first slot 301 and a second slot 302. The sealing assembly 4 is provided on the first connecting rod body 31 and located at the first slot 301 and the second slot 302. When the first connecting rod body 31 moves, the first spring 32 can be compressed or stretched. When the first spring 32 is compressed, the sealing assembly 4 separates from the base assembly 1, and the drain hole 101 and the drain side groove 102 open. When the first spring 32 is stretched, the sealing assembly 4 abuts against the base assembly 1, and the drain hole 101 and the drain side groove 102 close. By simultaneously inserting the first connecting rod body 31 through the limiting hole 201 provided in the connecting bracket 2 and the drain hole 101 and mating hole 103 provided in the base assembly 1, the position of the first connecting rod body 31 in the entire sealing structure 4 can be accurately determined, ensuring the relative positional accuracy between the connecting rod body 3 and the base assembly 1, thus laying the foundation for the normal operation of the entire sealing structure. A first spring 32 is clamped between the first connecting rod body 31 and the connecting bracket 2. Simultaneously, a sealing component 4 is positioned at the first slot 301 and the second slot 302 of the first connecting rod body 31. This allows the first connecting rod body 31 to drive the sealing component 4 to open and close the drain hole 101 and the drain side channel 102. When the drain hole 101 and drain side channel 102 need to be opened, the weight of the food processor overcomes the elastic force of the first spring 32, causing the first connecting rod body 31 to move. This, in turn, causes the sealing component 4 to leave the sealed position of the drain hole 101 and drain side channel 102, thus achieving the opening action. When the food processor is lifted, the elastic force of the first spring 32 causes the first connecting rod body 31 to return to its original position, closing the drain hole 101 and drain side channel 102. This automatic reset function simplifies the sealing process and reduces the need for manual intervention.

[0049] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines: the first connecting rod body 31 includes a first connecting rod 311 and a second connecting rod 312. The first connecting rod 311 passes through the limiting hole 201. The spring 32 is sleeved on the first connecting rod 311 and clamped between the first connecting rod 311 and the connecting bracket 2. The second connecting rod 312 is disposed on the first connecting rod 311. The second connecting rod 312 passes through the drain hole 101 and the mating hole 103 provided in the base assembly 1. The second connecting rod 312 is provided with a first slot 301 and a second slot 302. The sealing assembly 4 is disposed on the second connecting rod 312 and located at the first slot 301 and the second slot 302. By passing the first connecting rod 311 through the limiting hole 201 of the connecting bracket 2, and sleeved the spring 32 on the first connecting rod 311 and clamped between the first connecting rod 311 and the connecting bracket 2, precise guidance is provided for the movement of the first connecting rod 311. The shape and size of the limiting hole 201 are adapted to the first connecting rod 311, so that the first connecting rod 311 can only move in a specific direction and range. This guiding effect ensures that the movement trajectory of the first connecting rod 311 during equipment operation is predictable and stable. The second connecting rod 312 is then mounted on the first connecting rod 311 and passes through the mating hole 103. The second connecting rod 312 can be moved by pushing or pulling the first connecting rod 311 with the spring 32. This allows the sealing component 4 mounted on the first slot 301 and the second slot 302 of the second connecting rod 312 to open and close the drain hole 101 and the drain side groove 102. The elasticity of the spring 32 ensures that the sealing component 4 fits tightly against the drain device, providing sufficient sealing pressure. Combined with the flexibility of the sealing structure itself, this effectively enhances the sealing effect and ensures the safe use of the food processor.

[0050] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the base assembly 1 includes a first base 11, mounting pins 12, and a water-blocking assembly 13. There are multiple mounting pins 12, which are disposed on the first base 11. The connecting bracket 2 is disposed on the multiple mounting pins 12. The water-blocking assembly 13 is disposed on the first base 11. The first base 11 has a drain hole 101. The water-blocking assembly 13 cooperates with the first base 11 to form a drain side groove 102. The water-blocking assembly 13 has a mating hole 103. By disposing of multiple mounting pins 12 on the first base 11, the mounting pins 12 serve as connecting components between the connecting bracket 2 and the first base 11, increasing the stability of the connection. When the connecting bracket 2 is installed on the mounting pins 12, the mounting pins 12 can withstand a certain force. During equipment operation, the connecting bracket 2 may be subjected to the movement of the connecting rod assembly 3, external vibration, or other forces, causing a displacement tendency. The mounting pins 12 can effectively resist these forces, preventing the connecting bracket 2 from loosening or shifting relative to the first base 11. The water-blocking assembly 13 is mounted on the first base 11, which can block most of the water during washing at the drain hole 101, preventing washing water from entering the interior of the food processor. Simultaneously, the shape and structure of the drain side groove 102 formed by the water-blocking assembly 13 and the base assembly 1 helps guide the washing water towards the drain hole 101. It can concentrate the washing water accumulated on the first base 11, directing it to the drain hole 101 along a preset path, improving drainage efficiency and preventing washing water from accumulating inside the first base 11. The water-blocking assembly 13 has a mating hole 103, allowing the connecting rod assembly 3 to move within a defined space, ensuring reliable sealing.

[0051] like Figure 2 , Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water-blocking component 13 includes a water-blocking base 131 and a baffle 132. The water-blocking base 131 is disposed on the first base 11, and the baffle 132 is disposed on the water-blocking base 131. The baffle 132 is provided with a mating hole 103. By disposing of the water-blocking base 131 on the first base 11 and then disposing of the baffle 132 on the water-blocking base 131, the water-blocking base 131 can block the liquid from the main body of the food processor during washing, preventing the washing liquid from flowing directly into the food processor. The baffle 132, disposed on the water-blocking base 131, further enhances the waterproof capability, greatly preventing the intrusion of washing water and reducing splashing, effectively forming a double-layer protection system. By reasonably setting the position and shape of the water-blocking base 131 and the baffle 132, the drainage path can be optimized, effectively ensuring the dryness of the internal environment of the food processor and improving the overall service life and reliability of the food processor. The mating hole 103 provided on the stop 132 limits the range of motion of the connecting rod assembly 3, ensuring that the sealing assembly 4 can stably perform its sealing function for the food processor.

[0052] Example 2

[0053] like Figures 10 to 15 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the linkage assembly 3 includes a second linkage body 33 and a second spring 34, a sealing assembly 4 is disposed on the second linkage body 33, and the second spring 34 is sandwiched between the connecting bracket 2 and the second linkage body 33. When the second linkage body 33 moves, the second spring 34 can be compressed or stretched. When the second spring 34 is compressed, the sealing assembly 4 separates from the base assembly 1 and the drain hole 101 is opened. When the second spring 34 is stretched, the sealing assembly 4 abuts against the base assembly 1 and the drain hole 101 is closed. By placing the second spring 34 between the connecting bracket 2 and the second connecting rod body 33, when the food processor needs to be cleaned, the elasticity of the second spring 34 will push the second connecting rod body 33 downward, closing the drain hole 101 to prevent cleaning water from entering the interior of the food processor and ensuring a dry internal circuit environment. When the food processor is placed on a table, the second spring 34 is compressed between the connecting bracket 2 and the second connecting rod body 33. At this time, the second connecting rod body 33 rises closer to the mating hole 103, which also drives the sealing component 4 to move upward, opening the drain hole 101 and draining the internal water, keeping the inside of the food processor clean. The design of the second spring 34 allows the sealing component 4 to easily switch between open and closed states and ensures that the drain hole 101 remains closed when no external force is applied, preventing accidental liquid leakage.

[0054] like Figure 7 , Figure 13 and Figure 14As shown, in addition to the features of the above embodiments, this embodiment further defines the following: the second connecting rod body 33 includes a first push rod assembly 331, an intermediate connecting rod 332, and a second push rod assembly 333. The first push rod assembly 331, the intermediate connecting rod 332, and the second push rod assembly 333 are connected sequentially. The connecting bracket 2 is provided with a limiting hole 201. The first push rod assembly 331 passes through the limiting hole 201 of the connecting bracket 2, and the second push rod assembly 333 passes through the mating hole 103 of the base assembly 1. The sealing assembly 4 is disposed on the second push rod assembly 333. By having the first push rod assembly 331 pass through the connecting bracket 2 and be located at the limiting hole 201, the limiting hole 201 provides a clear movement boundary for the first connecting rod assembly 31. When the first connecting rod assembly 31 passes through the connecting bracket 2 and is located at the limiting hole 201, its movement trajectory is restricted within the range specified by the limiting hole 201. This constraint prevents excessive displacement or deviation from the predetermined movement path of the first linkage assembly 331 during operation. This is crucial for ensuring precise fit between the first linkage assembly 331 and the base assembly 1, avoiding malfunction of the entire device due to positional deviation of the first linkage assembly 331. The second push rod assembly 333 is mounted on the first push rod assembly 331, passing through the base assembly 1 and located at the mating hole 103. The mating hole 103 provides precise positioning and guidance for the second push rod assembly 333. Combined with the sealing assembly 4 mounted on the second push rod assembly 333, this enables precise opening and closing of the drain hole 101. The position of the mating hole 103 also determines the relative position of the second push rod assembly 333 within the base assembly 1, ensuring the rational spatial layout of the entire drainage control mechanism. The intermediate connecting rod 332 is mounted on the second push rod assembly 333, increasing its structural strength and ensuring stability under various complex stress conditions, reducing the possibility of structural loosening or failure.

[0055] like Figure 7 and Figure 14As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first push rod assembly 331 includes a first connecting rod 3311 and a first push block 3312. The first connecting rod 3311 passes through the limiting hole 201 of the connecting bracket 2. The two ends of the first push block 3312 are respectively connected to the first connecting rod 3311 and the intermediate connecting rod 332. The second spring 34 is sleeved on the first connecting rod 3311 and clamped between the connecting bracket 2 and the first push block 3312. By passing the first connecting rod 3311 through the connecting bracket 2 and positioning it at the limiting hole 201, the limiting hole 201 provides precise motion guidance for the first connecting rod 3311, enabling it to move along a specific direction. The first top block 3312 is placed on the first connecting rod 3311, and the second spring 34 is placed on the first connecting rod 3311 and sandwiched between the connecting bracket 2 and the first top block 3312. The presence of the second spring 34 enables the first connecting rod 3311 to have an automatic reset function. When an external force causes the first connecting rod 3311 to move, causing the first top block 3312 to squeeze the second spring 34, the second spring 34 is compressed and stores elastic potential energy. Once the external force disappears, the elastic potential energy of the second spring 34 will be released, pushing the first top block 3312, and then driving the first connecting rod 3311 back to the initial position, realizing the opening and closing of the drain hole 101, and ensuring the continuity and stability of the sealing structure.

[0056] like Figure 13 , Figure 14 and Figure 15As shown, in addition to the features of the above embodiments, this embodiment further defines that: the second push rod assembly 333 includes a second connecting rod 3331 and a second push block 3332, the second connecting rod 3331 is disposed on the intermediate connecting rod 332, the second connecting rod 3331 is disposed on the first push rod assembly 331, the second connecting rod 3331 passes through the base assembly 1 and is located at the mating hole 103, the second push block 3332 is disposed on the second connecting rod 3331, and the sealing assembly 4 is disposed on the second connecting rod 3331 and / or the second push block 3332. By placing the intermediate connecting rod 332 on the second connecting rod 3331, the structural strength of the second connecting rod 3331 can be improved, ensuring that the second connecting rod 3331 can work normally and stably. Placing the second connecting rod 3331 on the first push rod assembly 331 will play a role in force transmission. When the first push rod assembly 331 is subjected to the second spring force 34, it will simultaneously drive the second connecting rod 3331 to move. Since the second connecting rod 3331 is located at the mating hole 103 of the base assembly 1, it simultaneously seals the assembly 4 and the second push block 333. 2 is set on the second connecting rod 3331, so that when the second connecting rod 3331 is subjected to the force of the first push rod assembly 331, it can simultaneously drive the sealing assembly 4 and the second push block 3332 to move. Combined with the mating hole 103, it can precisely control the opening and closing of the drain hole 101. When the second spring 34 is stretched, the second push block 3332 will press the sealing assembly 4 against the drain hole 101, at which time the drain hole 101 is closed. When the second spring 34 is compressed, the second connecting rod 3331 will drive the sealing assembly 4 upward, at which time the drain hole 101 is opened.

[0057] like Figure 11 , Figure 12 and Figure 13As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the base assembly includes a second base 14, mating pins 15, and a drainage assembly 16. There are multiple mating pins 15, which are disposed on the second base 14. The connecting bracket 2 is disposed on the multiple mating pins 15, and the drainage assembly 16 is disposed on the second base 14. The drainage assembly 16 has a drainage hole 101 and a mating hole 103. By disposing of multiple mating pins 15 on the second base 14, a mounting position is provided for the connecting bracket 2. Through the cooperation with the mating pins 15, the connecting bracket 2 can be accurately placed in the designed position, ensuring that the connecting rod assembly 3 can be accurately aligned at the mating hole 103, thus ensuring the normal operation of the connecting rod assembly 3. Simultaneously, the multiple mating pins 15 provide a stable mounting foundation for the connecting bracket 2. When the connecting bracket 2 is installed on the multiple mating pins 15, a firm connection is formed between the connecting bracket 2 and the second base 14 through an appropriate connection method, further ensuring the stable operation of the connecting rod assembly 3 under the action of the second spring 34. The drainage component 16 is mounted on the second base 14. The drainage component 16 is provided with a drainage hole 101 and a mating hole 103. The drainage component 16 can be mated with the connecting rod assembly 3 through the mating hole 103. When the connecting rod assembly 3 is used to control drainage or waterproofing, one end of the connecting rod can be inserted into the mating hole. In this way, when the connecting rod moves, the opening and closing of the drainage hole 101 can be accurately controlled.

[0058] like Figure 12 and Figure 13As shown, in addition to the features of the above embodiments, this embodiment further defines: the drainage component 16 includes connecting blocks 161 and cylindrical blocks 162. There are multiple connecting blocks 161, which are spaced apart on the second base 14 and arranged in a ring. The cylindrical blocks 162 are disposed on the multiple connecting blocks 161 and have mating holes 103. The multiple connecting blocks 161, cylindrical blocks 162, and the second base 14 enclose each other to form multiple drainage holes 101. By arranging the multiple connecting blocks 161 along the circumference of the second base 14 and placing the cylindrical blocks 162 on the multiple connecting blocks 161, multiple drainage holes 101 are formed. Firstly, the presence of multiple drainage holes 101 significantly improves drainage efficiency. In equipment such as food processors, when internal liquid needs to be discharged, the liquid can flow out simultaneously through multiple drainage holes 101. Compared to a single drainage hole 101, multiple drainage holes 101 can increase the cross-sectional area of ​​the drainage. Secondly, multiple drain holes 101 help achieve uniform drainage. If there is only one drain hole, liquid tends to concentrate in that drain hole, which may lead to uneven liquid distribution inside the equipment, making it difficult for liquid in some areas to drain. Multiple drain holes 101 can guide the liquid to flow out from different directions, ensuring the cleanliness and dryness of the inside of the food processor. The mating hole 103 provided on the cylindrical block 162 provides a position for the mating and movement of the connecting rod assembly 3, ensuring that the connecting rod assembly 3 can move along the direction set by the mating hole 103.

[0059] like Figure 2 , Figure 7 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the connecting bracket 2 includes a bracket 21 and connecting sleeves 22, and there are multiple connecting sleeves 22, which are distributed on both sides of the bracket 21. The bracket 21 is connected to the base assembly 1 through the multiple connecting sleeves 22, and the bracket 21 is provided with limiting holes 201. By distributing multiple connecting sleeves 22 on both sides of the bracket 21, and then connecting the bracket 21 to the base assembly 1 using the connecting sleeves 22, this double-sided distribution structure can make the connection between the bracket 21 and the base assembly 1 more balanced. When subjected to force, the connecting sleeves 22 on both sides can evenly distribute the weight and other external forces from the bracket 21, avoiding the problem of uneven force distribution that may occur with a single-sided connection. The connecting sleeves 22 on both sides can work together to keep the bracket 21 stable and reduce the possibility of shaking and tilting. At the same time, the connecting sleeves 22 serve as connection points, and the existence of multiple connection points increases the reliability of the connection. Compared with a single-point connection, a multi-point connection can distribute the stress at the connection points. The supporting force of the base assembly 1 on the bracket 21 is transmitted through multiple connecting sleeves 22, which reduces the pressure on each connection point, thereby making the connection more robust and better able to withstand various complex external forces.

[0060] like Figures 1 to 15As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the connecting rod assembly 3 includes a connecting rod body and a solenoid valve assembly, and a sealing assembly 4 is disposed on the connecting rod body. The solenoid valve assembly can control the movement of the connecting rod body and open or close the drain hole 101 through the sealing assembly 4. The opening and closing of the drain hole 101 is achieved by controlling the movement of the connecting rod body using the solenoid valve assembly. Due to the control of the electrical signal, the solenoid valve assembly can precisely control the movement of the connecting rod body, thereby driving the sealing assembly to move. During drainage operation, when it is necessary to open or close the drain hole 101, the solenoid valve assembly receives an opening signal and drives the connecting rod body to move to a specific position. The solenoid valve assembly itself has a relatively stable structure, and its internal electromagnetic drive principle allows it to work stably for a relatively long time. When controlling the movement of the connecting rod body, as long as the power supply and signal transmission are normal, the solenoid valve can accurately complete the task. Compared with traditional mechanical control methods, this reduces problems such as wear and loosening of mechanical parts.

[0061] like Figures 1 to 15 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the connecting rod assembly 3 includes a connecting rod body and a magnet, and the sealing assembly 4 is disposed on the connecting rod body. The magnet can control the movement of the connecting rod body and open or close the drain hole 101 through the sealing assembly 4. By using a reasonably designed magnet layout and magnetic field strength to control the movement of the connecting rod body to drive the movement of the sealing assembly 4, the opening and closing of the drain hole 101 is realized. Since the magnet does not have the problem of component damage caused by friction between mechanical parts compared with the mechanical connection method, it can guide the connecting rod body to move stably along a specific path, thereby realizing the precise opening and closing of the drain hole 101. The movement of the connecting rod body will not be hindered due to mechanical parts wear, loosening, or other problems, thus improving the reliability of the sealing structure of the entire food processor.

[0062] Example 3

[0063] like Figures 1 to 15 As shown, this embodiment discloses a food processor, including: the sealing structure described above; and a food processor main unit, wherein the sealing structure is disposed on the food processor main unit.

[0064] The second aspect of this application discloses a food processor. By incorporating a sealing structure on the main unit of the food processor, it is possible for washing water to splash in from the bottom during the cleaning process. The sealing structure, through its sealing material, can tightly adhere to the drain hole 101. Utilizing its good flexibility and sealing properties, it can effectively prevent washing water from penetrating into the main unit, avoiding contact with sensitive electronic components such as the motor and circuit board, preventing component damage, and extending the service life of the food processor. More importantly, it can prevent users from experiencing electric shock while using the food processor, ensuring user safety and enhancing the market competitiveness of the food processor.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
