Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, specifically to a splash-proof food processing machine. Background Technology
[0002] Existing food processing machines, such as grinders, typically include a main unit and a grinding chamber within the main unit. The grinding chamber contains a moving grinding head and a stationary grinding head. When processing materials, the user places the material in the grinding chamber, and a motor drives the moving grinding head to rotate. The material is then ground between the moving and stationary grinding heads. To facilitate the addition of materials, the applicant's earlier patent application CN222130004U discloses a user-friendly food processing machine with a feeding channel vertically connected to the grinding chamber. A feeding port is located at the top of the feeding channel and is directly connected to the grinding chamber vertically. During the grinding process, when the material is subjected to the squeezing force of the moving and stationary grinding heads, especially harder materials, they may splash upwards with considerable force. If the user is near the food processing machine, this could cause injury and material waste, severely impacting the user experience. Utility Model Content
[0003] The purpose of this invention is to provide a splash-proof food processing machine to solve the problem that existing food processing machines, such as grinders, will cause material waste and safety risks to human health by splashing material particles during the grinding process.
[0004] To achieve the above objectives, this utility model provides a splash-proof food processing machine, including a main unit and a grinding chamber disposed within the main unit. The main unit also has a feeding bin located above the grinding chamber. The grinding chamber is provided with a moving grinding head and a stationary grinding head. The grinding chamber and the feeding bin are connected by a connecting channel, which is curved and connected to the side wall of the grinding chamber.
[0005] This application incorporates a moving grinding head and a stationary grinding head within the grinding chamber. When the user processes materials using the food processor, the motor drives the moving grinding head to rotate, causing relative grinding between the moving and stationary grinding heads to pulverize the material and meet the user's needs. Simultaneously, the grinding chamber and the feeding hopper are connected via a connecting channel. When the user adds material to the feeding hopper, the material can smoothly fall into the grinding chamber through the connecting channel and be processed within the grinding chamber by the rotation of the moving grinding head.
[0006] Meanwhile, the feeding hopper not only guides the material feeding but also collects powdery materials as they float upwards, preventing them from flying out and wasting material. Furthermore, the curved connecting channel, which connects to the side wall of the grinding chamber, allows harder materials to bounce back into the grinding chamber during grinding. This prevents splashing material from hitting the user and ensures thorough grinding, improving the grinding effect of the food processor. It also reduces powder splashing, minimizes waste, maintains a clean working environment, and enhances the user experience. In addition, the combination of the feeding hopper and the connecting channel greatly extends the entire feeding channel, so that the material needs to travel a longer and more tortuous path when it splashes outward, which further enhances the obstruction of the material.
[0007] In a preferred embodiment of a splash-proof food processing machine, the main unit includes a housing forming a grinding chamber, a communicating channel formed within the housing, a stationary grinding head being a cylindrical stationary grinding cylinder, and a feed inlet communicating with the communicating channel on the side wall of the stationary grinding cylinder.
[0008] By integrating the grinding chamber and the connecting channel within the housing, the need for a separate structural component to form the connecting channel is eliminated. This simplifies the overall structure of the machine, improves its stability, and streamlines the assembly process, enhancing efficiency. It also avoids gaps between the connecting channel and the grinding chamber caused by the connection of the two components, preventing material residue from accumulating in these gaps and improving the overall cleanliness of the machine. Furthermore, the side wall of the stationary grinding cylinder has a feed inlet connected to the connecting channel, allowing material to move downwards through the channel and directly enter the space between the moving and stationary grinding heads for grinding, achieving more efficient material processing.
[0009] In a preferred embodiment of a splash-proof food processing machine, the housing includes an outer shell and a base disposed below the outer shell, the outer shell and the base enclose a grinding chamber, and the base is provided with a powder outlet communicating with the grinding chamber.
[0010] By designing the housing as a combination of an outer shell and a base located beneath it, the outer shell and base together form a grinding chamber. This allows for smooth installation of the food processor by first installing the stationary grinding head into the outer shell and then securing the base to the bottom of the outer shell. Simultaneously, the base has a powder outlet communicating with the grinding chamber, enabling efficient discharge of ground powder. This prevents powder accumulation inside the grinding chamber, ensuring machine cleanliness and hygiene, while simultaneously improving food processing efficiency and quality.
[0011] In a preferred embodiment of a splash-proof food processing machine, a mounting cavity is provided inside the housing, and a stationary grinding head is mounted and fixed inside the mounting cavity.
[0012] In a preferred embodiment of a splash-proof food processing machine, the feeding bin and the housing are separate parts, the feeding bin is fixed above the housing, and the side wall or bottom wall of the feeding bin is provided with a discharge port that communicates with the connecting channel.
[0013] By designing the feeding hopper and the housing as separate components, with the feeding hopper fixed above the housing, the molding and processing of both components are facilitated. The separate design also allows for independent replacement of the feeding hopper and housing. If damage occurs due to user error such as collisions or drops, only the damaged parts need to be replaced, reducing maintenance costs, extending the equipment's lifespan, and improving the user experience. Furthermore, the feeding hopper's side or bottom wall has a discharge port connected to the connecting channel, ensuring that materials poured into the feeding hopper smoothly enter the connecting channel and are successfully ground in the grinding chamber.
[0014] In a preferred embodiment of a splash-proof food processing machine, the main unit includes a housing forming a grinding chamber, with a stationary grinding head integrally formed with the housing.
[0015] By making the stationary grinding head and the housing a single piece, the component structure is simplified. The stationary grinding head is formed at the same time as the housing. This not only reduces the steps of assembling the two together, which helps to improve assembly efficiency, but also avoids problems such as material leakage and collision noise caused by gaps between the stationary grinding head and the housing, which helps to improve the user experience of the material processing process.
[0016] In a preferred embodiment of a splash-proof food processing machine, the bottom wall of the feeding hopper is provided with a discharge port that communicates with the inlet end of the connecting channel, and the diameter of the discharge port is smaller than the diameter of the connecting channel.
[0017] By setting the discharge port diameter to be smaller than the connecting channel diameter, when the material is being ground in the grinding chamber, some of the material is squeezed and splashed upwards. This is further blocked by the discharge port diameter, and together with the curved connecting channel, it achieves double splash prevention, effectively preventing splashing, ensuring the stability and safety of the grinding process, and improving the processing effect.
[0018] In a preferred embodiment of a splash-proof food processing machine, the top wall of the grinding chamber is provided with a limiting hole with an opening at the bottom, and the positioning pin at the top of the moving grinding head is inserted into the limiting hole.
[0019] By providing a limiting hole with an opening at the bottom on the top wall of the grinding chamber, and inserting the positioning pin at the top of the moving grinding head into the limiting hole, the bottom of the moving grinding head is limited by the bottom wall of the grinding chamber, while the top is effectively limited by the positioning pin and the limiting hole. This ensures that the moving grinding head operates stably during the grinding process, avoids uneven grinding or even jamming caused by vibration or displacement, further improves grinding accuracy and efficiency, and ensures food processing quality.
[0020] In a preferred embodiment of a splash-proof food processing machine, an isolation element is further provided inside the limiting hole, and the isolation element has a positioning hole that engages with the positioning post.
[0021] By providing an isolation component within the limiting hole, and having a positioning hole that engages with the positioning post, the positioning post and the limiting hole are isolated. This prevents the positioning post from directly contacting the limiting hole during the rotation of the moving grinding head. The contact with the high-strength isolation component effectively avoids wear on the limiting hole, thereby preventing radial positioning errors caused by wear. This avoids significant swaying of the moving grinding head during rotation, which could lead to uneven material wear or even jamming. This ensures the stability of the housing's positioning of the moving grinding head, extends the equipment's service life, improves overall processing efficiency, and guarantees the quality of food processing.
[0022] In a preferred embodiment of a splash-proof food processing machine, the feeding hopper includes a hopper body and a cover that covers the top of the hopper body.
[0023] By configuring the feeding hopper as a hopper body and a cover that fits over the hopper body, the cover can achieve a sealed cover over the hopper body, isolating the hopper body from the outside world and further preventing material from splashing outwards during processing. Combined with the curved connecting channel, this achieves double blocking of material splashing inside the grinding chamber, ensuring the safety and hygiene of the material processing process.

Detailed Implementation
[0030] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0031] 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.
[0032] like Figures 1 to 3 As shown, this utility model provides a splash-proof food processing machine, including a main unit and a grinding chamber 2 disposed in the main unit. The main unit is also provided with a feeding bin 1 located above the grinding chamber 2. The grinding chamber 2 is provided with a moving grinding head 4 and a stationary grinding head 3. The grinding chamber 2 and the feeding bin 1 are connected by a connecting channel 6. The connecting channel 6 is curved and connected to the side wall of the grinding chamber 2.
[0033] This application, by providing a moving grinding head 4 and a stationary grinding head 3 within the grinding chamber 2, allows the user to process materials using the food processor. The motor drives the moving grinding head 4 to rotate, and the material undergoes relative grinding between the moving grinding head 4 and the stationary grinding head 3 to achieve pulverization, thus meeting the user's needs. Simultaneously, the grinding chamber 2 is connected to the feeding bin 1 via a connecting channel 6. When the user adds material to the feeding bin 1, the material can smoothly fall into the grinding chamber 2 through the connecting channel 6, where it is processed by the rotation of the moving grinding head 4.
[0034] Meanwhile, the feeding bin 1 not only guides the material feeding but also collects powdery materials as they float upwards, preventing them from flying out and wasting material. Furthermore, the curved connecting channel 6 connects to the side wall of the grinding chamber 2. Compared to the existing scheme where the feeding bin 1 and grinding chamber 2 are vertically connected, this design allows harder materials to collide with the wall of the connecting channel 6 when squeezed upwards by the moving grinding head 4. The rebound from the wall returns the material to the grinding chamber 2, where it continues to be ground. The curved connecting channel 6 effectively blocks splashing material, preventing it from hitting the user and ensuring thorough grinding. This improves the grinding effect of the food processor, reduces powder splashing, minimizes waste, maintains a clean working environment, and enhances the user experience. In addition, the feeding bin 1 and the connecting channel 6 work together to greatly extend the entire feeding channel, so that the material needs to go through a longer and more tortuous path when it splashes outward, which further enhances the obstruction of the material.
[0035] As a preferred embodiment of this application, such as Figure 1 As shown, the main unit includes a housing 5 forming a grinding chamber 2, a connecting channel 6 formed inside the housing 5, and a stationary grinding head 3 being a cylindrical stationary grinding cylinder. The side wall of the stationary grinding cylinder is provided with a feed port 31 that communicates with the connecting channel 6.
[0036] By embedding both the grinding chamber 2 and the connecting channel 6 within the housing 5, the need for a separate structural component to form the connecting channel 6 is eliminated. This not only simplifies the overall structure and improves the overall stability of the equipment, but also simplifies the assembly process, improving assembly efficiency. Furthermore, it avoids gaps between the connecting channel 6 and the grinding chamber 2 caused by the connection of the two components, preventing material residue from accumulating in these gaps and improving the overall cleanliness of the machine. Additionally, the side wall of the stationary grinding cylinder has a feed inlet 31 that communicates with the connecting channel 6, allowing material to move downwards through the connecting channel 6 and directly enter the space between the moving grinding head 4 and the stationary grinding head 3 for grinding, achieving more efficient material processing.
[0037] It should be noted that this application does not specifically limit the molding of the grinding chamber 2 in this embodiment, and it can be any one of the following embodiments:
[0038] Example 1: As Figure 1 As shown, in this embodiment, the housing 5 includes an outer shell 51 and a base 52 disposed below the outer shell 51. The outer shell 51 and the base 52 enclose a grinding chamber 2, and the base 52 is provided with a powder outlet 521 communicating with the grinding chamber 2.
[0039] By configuring the housing 5 to include an outer shell 51 and a base 52 located below the outer shell 51, the outer shell 51 and the base 52 together form a grinding chamber 2. This allows the food processor to be installed smoothly during production and assembly. The stationary grinding head 3 can be installed inside the outer shell 51, and then the base 52 can be fixedly connected to the bottom of the outer shell 51. Simultaneously, the base 52 has a powder outlet 521 communicating with the grinding chamber 2, allowing the ground powder to be efficiently discharged from the outlet 521, preventing powder accumulation inside the grinding chamber 2, ensuring the cleanliness and hygiene of the machine, and improving the efficiency and quality of food processing.
[0040] As a preferred embodiment, such as Figure 1 As shown, the housing 5 has an installation cavity, and the stationary grinding head 3 is installed and fixed in the installation cavity.
[0041] Example 2: In this example, the main unit includes a housing 5 forming the grinding cavity 2, and the stationary grinding head 3 is integrally formed with the housing 5. In this example, since the stationary grinding head 3 is integrally formed with the housing 5, the grinding cavity 2 is actually formed inside the stationary grinding head 3.
[0042] By making the stationary grinding head 3 and the housing 5 as a single piece, the component structure is simplified. The stationary grinding head 3 is formed at the same time as the housing 5. This not only reduces the steps of assembling the two together, which helps to improve assembly efficiency, but also avoids problems such as material leakage and collision noise caused by the gap between the stationary grinding head 3 and the housing 5, which helps to improve the user experience of the material processing process.
[0043] As a preferred embodiment of this implementation, such as Figure 1 As shown, the feeding bin 1 and the shell 5 are separate parts. The feeding bin 1 is fixed above the shell 5, and the side wall or bottom wall of the feeding bin 1 is provided with a discharge port 13 that communicates with the connecting channel 6.
[0044] By designing the feeding bin 1 and the housing 5 as separate components, with the feeding bin 1 fixed above the housing 5, the molding and processing of the feeding bin 1 and the housing 5 are facilitated. The separate design also allows for independent replacement of the feeding bin 1 and the housing 5. If damage occurs due to user error such as collisions or drops, only the damaged parts need to be replaced, reducing maintenance costs, extending the equipment's lifespan, and improving the user experience. Furthermore, the feeding bin 1 has a discharge port 13 on its side or bottom wall that connects to the connecting channel 6. This allows materials poured into the feeding bin 1 to smoothly enter the connecting channel 6 through the discharge port 13, ensuring the materials successfully enter the grinding chamber 2 for grinding.
[0045] Of course, the feeding bin 1 and the shell 5 can also be a single piece, formed as one piece during the production process, which will not be elaborated here.
[0046] As a preferred embodiment of this application, such as Figure 1 As shown, the bottom wall of the feeding bin 1 is provided with a discharge port 13 that is connected to the inlet end of the connecting channel 6. The diameter of the discharge port 13 is smaller than the diameter of the connecting channel 6.
[0047] By setting the diameter of the feed inlet 13 to be smaller than that of the connecting channel 6, when the material is being ground in the grinding chamber 2, some of the material is squeezed and splashed upwards. This is further blocked by the limitation of the feed inlet 13 diameter. In conjunction with the curved connecting channel 6, double splash prevention is achieved, which effectively prevents splashing, ensures the stability and safety of the grinding process, and improves the processing effect.
[0048] As a preferred embodiment of this application, such as Figure 1 As shown, the top wall of the grinding chamber 2 is provided with a limiting hole 21 with an opening at the bottom, and the positioning pin at the top of the moving grinding head 4 is inserted into the limiting hole 21.
[0049] By providing a limiting hole 21 with a bottom opening on the top wall of the grinding chamber 2, and inserting the positioning pin at the top of the moving grinding head 4 into the limiting hole 21, the bottom of the moving grinding head 4 is limited by the bottom wall of the grinding chamber 2, while the top is effectively limited by the positioning pin and the limiting hole 21. This ensures that the moving grinding head 4 operates stably during the grinding process, avoids uneven grinding or even jamming caused by vibration or displacement, further improves grinding accuracy and efficiency, and ensures food processing quality.
[0050] Furthermore, such as Figure 1 As shown, the limiting hole 21 is also provided with an isolation member 8, and the isolation member 8 is provided with a positioning hole that is inserted and matched with the positioning post.
[0051] By providing an isolation element 8 inside the limiting hole 21, and the isolation element 8 having a positioning hole that engages with the positioning post, the positioning post and the limiting hole 21 are isolated. This ensures that the positioning post will not directly contact the limiting hole 21 during the rotation of the moving grinding head 4. By contacting the high-strength isolation element 8, wear of the limiting hole 21 can be effectively avoided, thereby preventing radial positioning errors caused by wear of the limiting hole 21. This would prevent the moving grinding head 4 from swaying significantly during rotation, resulting in uneven material wear or even jamming. This ensures the stability of the housing 5 in limiting the moving grinding head 4, extends the service life of the equipment, improves the overall processing efficiency, and guarantees the quality of food processing.
[0052] More preferably, the main unit also includes fasteners 9 that pass sequentially through the top wall of the isolation member 8 and the grinding chamber 2 and are fastened to the feeding bin 1. Preferably, the isolation member 8 is made of metal, such as stainless steel. This ensures that the isolation member 8 is fastened to the limiting hole 21 by the fasteners 9, guaranteeing the stability of the connection between the isolation member 8 and the fasteners 9. At the same time, the fasteners 9 can also fix the feeding bin 1 and the housing 5 as a whole, realizing the dual function of the fasteners 9, further enhancing the overall structural stability of the equipment, reducing noise and vibration caused by loose assembly, and improving the user experience.
[0053] It should be noted that this application does not specifically limit the structure of the feeding bin 1. As one preferred embodiment of this application, such as... Figure 1 As shown, the feeding bin 1 includes a bin body 11 and a cover 12 that covers the top of the bin body 11.
[0054] By setting the feeding bin 1 to include a bin body 11 and a cover 12 covering the bin body 11, the cover 12 can seal and cover the bin body 11, isolating the bin body 11 from the outside world, further preventing material from splashing outward during processing. Combined with the curved connecting channel 6, the material in the grinding chamber 2 is doubly blocked from splashing, ensuring the safety and hygiene of the material processing process.
[0055] Furthermore, such as Figure 1 As shown, one end of the cover 12 is hinged to the chamber 11, and the other end is snapped into the chamber 11. A switch linkage 7 that moves with the cover 12 is provided on the side of the chamber 11 that is hinged to the cover 12. The main unit is equipped with a micro switch that cooperates with the switch linkage 7. When the cover 12 is closed, the switch linkage 7 moves downward and triggers the micro switch, so that the food processor can be opened and operated. When the cover 12 is open or not closed, the switch linkage 7 moves upward through the spring and separates from the micro switch. At this time, the motor cannot be opened and operated, so as to prevent the user from processing materials when the cover 12 is not closed.
[0056] It should be noted that this application does not limit the specific structure of the connecting channel 6. As one preferred embodiment of this application, such as... Figure 1 As shown, the connecting channel 6 includes a first bent section that communicates with the side wall of the grinding chamber 2 and a second bent section that communicates with the feeding bin 1. The multiple bends provide multiple splash protection for the material, which helps to further improve the splash protection effect.
[0057] As a preferred embodiment of this application, such as Figure 1As shown, the bottom wall of the feeding bin 1 is provided with a discharge port 13 that communicates with the connecting channel 6. The feeding bin 1 is provided with a guide surface 14 that extends downward towards the discharge port 13, so that when the user adds materials into the feeding bin 1, the materials are guided by the guide surface 14 to enter the connecting channel 6 and the grinding chamber 2 through the discharge port 13 for grinding, which helps to improve the efficiency of the material moving downward, thereby improving the efficiency of material processing.
[0058] As a preferred embodiment of this application, such as Figure 1 , Figure 3 As shown, the inner wall of the feeding bin 1 is provided with a baffle surface 15 facing the inlet end of the connecting channel 6, such as... Figure 1 As shown, the stop surface 15 can extend upward at an angle, such as... Figure 3 As shown, the baffle surface 15 can also extend downward at an angle to further block the material.
[0059] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
