Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a silent food processor with a double-layer soundproof cover. Background Technology

[0002] A soundproof enclosure is a device used to reduce or block the propagation of sound. It is typically made of sound-absorbing and sound-insulating materials and can effectively reduce noise levels. It is widely used in various applications, such as with machinery, engines, and air conditioning systems, to reduce the impact of noise on the surrounding environment. Its working principle is to absorb, reflect, or scatter sound waves to reduce the volume of the noise source. A food processor is a multi-functional kitchen appliance mainly used for cutting, mixing, grinding, and blending food ingredients. It usually comes with multiple interchangeable blades and attachments to perform various cooking tasks. Food processors can efficiently process various ingredients and are commonly used to make juices, soups, smoothies, blend batters, grind coffee beans, and chop vegetables.

[0003] The food processor effectively reduces noise during operation by using a low-noise motor, optimized blade design, shock-resistant materials and a thick outer shell, as well as improvements to the internal structure. The lack of a soundproof cover prevents the machine from achieving its maximum noise reduction during use.

[0004] In existing technologies, most food processors use a single-layer shell design. Although some products have improved in terms of materials and used sound-insulating materials, their sound insulation effect is still limited. This is because a single-layer structure cannot effectively block sound waves, allowing noise to easily propagate during operation. Furthermore, existing soundproof covers often lack the necessary stability, making them prone to loosening and detachment during use, increasing user anxiety and affecting the overall user experience. Therefore, a silent food processor with a double-layer soundproof cover is proposed to solve these problems. Utility Model Content

[0005] The present invention proposes a silent food processor with a double-layer soundproof cover, which aims to improve the problem of some existing food processors being unable to operate without noise.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A silent food processor with a double-layer soundproof cover includes a base. Multiple connecting columns are fixedly connected to the top of the base. Limiting components are fixedly connected to the outside of the connecting columns. A second sealing ring is fixedly connected to the top of the base. A first sealing ring is slidably connected to the top of the second sealing ring. A noise reduction mechanism is fixedly connected to the top of the first sealing ring. A connecting plate is fixedly connected to the top of the base. The food processor body is rotatably connected to the top of the connecting plate. A lid is rotatably connected to the inside of the food processor body. A switching mechanism is fixedly connected to the inside of the food processor body.

[0008] The noise reduction mechanism includes an inner soundproof cover, the bottom of which is fixedly connected to the top of the first sealing ring. Two sponge pads are fixedly connected inside the inner soundproof cover. An outer soundproof cover is fixedly connected to the top of the first sealing ring. A handle is fixedly connected to the top of the outer soundproof cover. An air pump is fixedly connected to the top of the handle. Multiple limiting rings are fixedly connected to the bottom of the first sealing ring.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a fixing block, the inside of which is fixedly connected to the outside of the connecting post, and the outside of the connecting post is slidably connected to the inside of the sealing ring.

[0011] As a further description of the above technical solution:

[0013] As a further description of the above technical solution:

[0014] The locking assembly includes a connecting ring, the bottom of which is fixedly connected to the top of the food processor body, and a rotating block is threadedly connected to the inside of the connecting ring.

[0015] As a further description of the above technical solution:

[0016] The bottom of the cross plate is rotatably connected to the inside of the food processor body, and the inside of the food processor body is slidably connected to the outside of the blade.

[0017] As a further description of the above technical solution:

[0018] The rotating block is internally slidably connected to the outside of the connecting rod, and the rotating block is internally slidably connected to the outside of the clamping jaw.

[0019] As a further description of the above technical solution:

[0020] The outer part of the fixing block is slidably connected to the inside of the limiting ring, and the inner part of the limiting ring is slidably connected to the outside of the connecting post.

[0021] As a further description of the above technical solution:

[0022] The inner soundproof cover is slidably connected to the outside of the food processor body, and the outside of the food processor body is slidably connected to the outside of the sponge pad.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by installing a connecting column on the base and applying force to the handle, the outer soundproof cover and the inner soundproof cover can slide on the connecting column. After reaching the top, the limiting ring of the soundproof cover is fixed at the top of the connecting column by the fixing block, which prevents the soundproof cover from being easily lost during normal use.

A sealing ring 1 6 is slidably connected to the top of the sealing ring 2 11. A noise reduction mechanism is fixedly connected to the top of the sealing ring 1 6. The noise reduction mechanism includes an inner sound insulation cover 5. The inner sound insulation cover 5 is an inverted bowl-shaped structure. Its material is a composite of special sound-absorbing material and high-strength plastic. On the one hand, it has sufficient strength to maintain its shape, and on the other hand, it has excellent sound absorption performance, which can effectively block the noise generated inside the food processor from spreading outward. The inner soundproof cover 5 is slidably connected to the outside of the food processor body 13. The outside of the food processor body 13 is slidably connected to the outside of the sponge pads 8. The bottom of the inner soundproof cover 5 is fixedly connected to the top of the sealing ring 6. Two sponge pads 8 are fixedly connected inside the inner soundproof cover 5. The sponge pads 8 are made of soft and porous sponge material, providing good cushioning and sound absorption. Their shape conforms to the outer contour of the food processor body 13, forming a ring around the outside of the food processor body 13. The top of the sealing ring 6 is fixedly connected to the outer soundproof cover 4, which is also an inverted bowl shape, but its size is slightly larger than that of the inner soundproof cover 5. The outer soundproof cover 4 is made of a composite material of sound-absorbing and high-strength materials. The top of the outer soundproof cover 4 is fixedly connected to a handle 10. The handle 10 is shaped to be easy for people to hold, and is curved. It is made of non-slip and durable plastic material, providing users with a convenient point of leverage to pick up the food processor. The top of the handle 10 is fixedly connected to a vacuum pump 9. The vacuum pump 9 is a small rectangular device with precision motors, impellers and other components inside. The outer shell is made of sturdy and heat-dissipating aluminum alloy. Its main function is to draw air between the inner and outer soundproof covers 4 to create a certain negative pressure environment, further improving the sound insulation effect. The bottom of the sealing ring 6 is fixedly connected to multiple limiting rings 7.

[0035] Reference Figure 3 , Figure 4A connecting plate 12 is fixedly connected to the top of the base 1. The connecting plate 12 is disc-shaped and made of wear-resistant and high-strength engineering plastic. A food processor body 13 is rotatably connected to the top of the connecting plate 12. Driven by a motor or other power source, the food processor body 13 rotates around the connection point with the connecting plate 12 to perform operations such as blending food. A lid 14 is rotatably connected inside the food processor body 13. The lid 14 is circular and flat, with a certain curvature around the edges, and is made of transparent and high-temperature resistant plastic, allowing users to easily observe the internal workings of the food processor. A switching mechanism is fixedly connected inside the food processor body 13. The switching mechanism includes a connecting block 15, which is a block structure made of sturdy stainless steel, providing a stable support base for the related components above. The bottom of the connecting block 15 is fixedly connected to the inside of the food processor body 13, and the top of the connecting block 15 is fixedly connected to a clamping claw 16. The clamping claw 16 is shaped like multiple curved fingers and is made of high-strength alloy steel, which has good clamping and fixing capabilities. A connecting rod 19 is slidably connected inside the clamping claw 16. The connecting rod 19 is made of a metal material with good toughness, which can withstand a certain amount of tension and pressure, and its surface is finely polished to reduce friction with the clamping claw 16.

[0036] A cross plate 20 is fixedly connected to the top of the connecting rod 19. The cross plate 20 is cross-shaped with rounded ends and is made of sturdy stainless steel. The bottom of the cross plate 20 is rotatably connected to the inside of the food processor body 13. The inside of the food processor body 13 is slidably connected to the outside of the blades 21. Multiple blades 21 are fixedly connected to the top of the cross plate 20. The blades 21 are of various shapes, curved and arc-shaped, and are made of extremely hard stainless steel. They are manufactured through a sophisticated forging process and can quickly and effectively chop ingredients. A locking assembly is fixedly connected to the top of the connecting block 15. The locking assembly includes a connecting ring 17, which is circular in shape and made of high-strength alloy steel. The bottom of the connecting ring 17 is fixedly connected to the top of the food processor body 13. A rotating block 18 is threadedly connected to the inside of the connecting ring 17. The rotating block 18 is a cylinder with external threads and is made of wear-resistant and moderately hard metal. The inside of the rotating block 18 is slidably connected to the outside of the connecting rod 19 and the inside of the rotating block 18 is slidably connected to the outside of the clamping claw 16.

[0037] Working Principle: First, the user places the ingredients into the food processor body 13 and ensures that the lid 14 is correctly installed on the opening of the food processor body 13. Then, the user starts the food processor, and the motor drives the connecting plate 12, causing the food processor body 13 to rotate around the connection point. At this time, the blades 21 rotate at high speed under the drive of the motor, cutting and mixing the ingredients. Simultaneously, the soundproof space formed by the inner soundproof cover 5 and the outer soundproof cover 4 effectively suppresses the noise generated during operation, ensuring that the user is not disturbed by noise during operation. When the food processor is working, the vacuum pump 9 starts operating, drawing air from between the inner and outer soundproof covers 4 to create a negative pressure environment, thereby further enhancing the sound insulation effect. The composite structure of the special sound-absorbing material and high-strength plastic in the inner soundproof cover 5 effectively blocks noise from spreading outward, improving the quietness effect. In addition, the soft properties of the sponge pad 8 provide good cushioning and sound absorption for the food processor body 13, further reducing noise. The design of the sealing ring 1 6 and sealing ring 2 11 ensures the sealing of the food processor, preventing leakage of ingredients and liquids, while also enhancing the sound insulation effect. Applying force to the handle 10 allows the outer soundproof cover 4 and the inner soundproof cover 5 to slide on the connecting column 2. After reaching the top, the limiting ring 7 of the soundproof cover is stabilized at the top of the connecting column 2 by the fixing block 3, preventing the soundproof cover from being easily lost during normal use.

[0038] During operation, when different ingredients need to be processed, rotating the rotating block 18 causes the rotating column to face upwards inside the connecting ring 17. Because the connecting ring 17 has a special groove, the clamping claws 16 are not restrained by the rotating block 18, allowing them to spread outwards. This allows the connecting rod 19 and its connected cross plate 20 blade 21 to be removed, and different types of blades 21 can be placed as needed. This device design allows users to enjoy efficient blending while reducing the discomfort caused by noise when using the food processor.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
