[0002] Currently, blenders are generally used for processing ingredients such as fruits, vegetables, and baby food, primarily through a motor driving a cutting blade. However, existing blenders generate considerable noise during operation due to the high motor and blade speeds.

The driving end is used to drive the connecting end to move closer to or away from the pressure-receiving member under the action of external force. The pressing member is used to press against the pressure-receiving member after the connecting end moves closer to the pressure-receiving member, so as to drive the sealing member to move downward.

[0006] Furthermore, a cabinet door is hinged to the cabinet body, and the cabinet door is used to rotate closer to or further away from the processing cavity; the cabinet door is connected to the drive end, and the cabinet door is used to drive the drive end to move during rotation, so as to drive the connection end closer to or further away from the pressure-bearing component.

[0007] Furthermore, the top pressing member is provided with a top pressing inclined surface, and the pressure receiving member is provided with a pressure receiving inclined surface, and the top pressing inclined surface and the pressure receiving inclined surface are in sliding engagement.

[0008] Furthermore, the sealing component is provided with an exhaust channel, the top of which is provided with an exhaust hole; the bottom of which is provided with an air inlet; a sealing sheet is provided inside the exhaust channel, which seals and covers the air inlet. The sealing sheet is used to be pushed away from the air inlet by the gas pressure when air enters the air inlet, so as to open the air inlet.

[0009] Furthermore, the multi-functional mixer also includes a connecting assembly, which includes a first connector, a second connector, and a noise reduction component.

[0018] The present invention will now be further described with reference to the accompanying drawings and specific embodiments: In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0020] like Figure 1-6 The multi-functional mixer shown includes a base 10, a cabinet 20, and a sealing assembly 30. The base 10 has a mounting cavity with an air inlet on the bottom wall and an air outlet 11 on the side wall. Specifically, the mounting cavity contains a soundproof cover 52 and a heat dissipation base 53. A drive component 51 is located inside the soundproof cover 52. The outer wall of the soundproof cover 52 and the inner wall of the mounting cavity form a first channel 57 communicating with the air inlet. Since the soundproof cover 52 covers the drive component 51, the inner wall of the soundproof cover 52 and the outer surface of the drive component 51 can form a second channel 58 at intervals. The top end of the second channel 58 communicates with the top end of the first channel 57. The heat dissipation base 53 is connected to the bottom end of the soundproof cover 52. A heat dissipation cavity 531 is located inside the heat dissipation base 53, communicating with the bottom end of the second channel 58 and connecting the heat dissipation cavity 531 to the air outlet 11. A cooling fan is located inside the heat dissipation cavity 531.

[0021] The cabinet 20 has a processing chamber 22 and a through opening 23 communicating with the processing chamber 22. The cabinet 20 is mounted on the base 10. After the cabinet 20 is mounted on the base 10, the drive component 51, after being assembled into the mounting cavity, will have its rotating shaft extending from the top of the base 10, and this shaft can extend into the processing chamber 22. A food preparation cup 40 is detachably mounted inside the processing chamber 22. After the food preparation cup 40 is assembled into the processing chamber 22, the blade assembly 41 inside the food preparation cup 40 can be connected to the rotating shaft of the drive component 51. Furthermore, a feeding port can be provided on the food preparation cup 40.

[0022] Alternatively, the aforementioned sealing component 30 can be disposed at the through-hole 23. The sealing component 30 can move along the height direction of the through-hole 23, that is, the sealing component 30 can move up and down within the through-hole 23. After the food preparation cup 40 is assembled into the processing chamber 22, the feeding port of the food preparation cup 40 can correspond to the through-hole 23. The aforementioned sealing component 30 can move downward and extend from the through-hole 23 into the processing chamber 22 to seal the feeding port.

[0023] Based on the above structure, when using the multifunctional mixer of the present invention, the ingredients to be mixed can be added to the outside of the cabinet 20 through the feeding port of the mixing cup 40. After the ingredients are added, the mixing cup 40 can be placed into the processing chamber 22 of the cabinet 20, and the feeding port at the top of the mixing cup 40 can correspond to the through-hole 23 on the cabinet 20. At this time, the sealing component 30 can move downward, extending from the bottom end of the through-hole 23 into the processing chamber 22, and sealing the feeding port of the mixing cup 40. After that, the drive component 51 can be activated. The rotating shaft of the drive component 51 and the blade assembly 41 of the mixing cup 40 can be connected through the coupling 511. The drive component 51 drives the blade assembly 41 of the mixing cup 40 to rotate, sealing the feeding port. In this way, the sealing component 30 can reduce the noise caused by the rotation of the blade assembly 41 during the mixing process, and also prevent the ingredients in the mixing cup 40 from splashing out during the mixing process, making the processing process cleaner and more hygienic.

[0024] In addition, the sealing component 30 of the through port 23 can also move upward in the through port 23 during the processing. The sealing component 30 can open the through port 23 and the feeding port, which can realize secondary feeding during the mixing process.

[0025] It should also be noted that the shaft of the drive component 51 generates considerable noise during rotation. Furthermore, a cooling fan is required to dissipate heat during operation. If the drive component 51 and the cooling fan are directly installed within the mounting cavity of the base 10, the operating noise generated by them will be excessive, negatively impacting the user experience.

[0026] Therefore, in this application, the driving component 51 can be installed outside the soundproof cover 52, and the cooling fan can be installed in the heat dissipation cavity 531 of the heat dissipation base 53, with the bottom end of the soundproof cover 52 communicating with the heat dissipation cavity 531. Based on this structure, during the rotation of the cooling fan and the cooling fan base, the gas in the heat dissipation cavity 531 can flow to form a negative pressure. The external airflow can be introduced through the first channel 57 between the soundproof cover 52 and the outer wall of the mounting cavity. Since the air inlet is located at the bottom end of the mounting cavity, the airflow is guided from bottom to top to the top of the first channel 57, and then introduced into the soundproof cover 52 through the top of the soundproof cover 52. It is then guided from top to bottom to the bottom end of the second channel 58 and enters the heat dissipation cavity 531, and is then guided through the heat dissipation cavity 531 to the air outlet 11 for discharge.

[0027] In the above process, the airflow is introduced through the first channel 57 of the outer layer and then flows through the second channel 58 of the inner layer, realizing the detour flow of the gas, extending the gas flow path to increase heat dissipation performance, and reducing the noise generated by concentrated airflow. In addition, the drive component 51 and the cooling fan are both covered by the soundproof cover 52 and the heat dissipation base 53, which can further reduce the operating noise of the drive component 51 and the cooling fan.

[0028] Of course, the aforementioned drive component 51 can also be implemented using a motor structure from the prior art.

[0029] Furthermore, the sealing assembly 30 includes a sealing element and a linkage mechanism. The sealing element can be inserted into the through-hole 23, and the sealing element can move up and down along the height direction of the through-hole 23. Specifically, the linkage mechanism includes a linkage rod 31, a pressing element 32, and a pressure-receiving element. One end of the linkage rod 31 is formed as a driving end, and the other end of the linkage rod 31 is formed as a connecting end. Specifically, the connecting end is connected to the pressing element 32, and the pressure-receiving element is connected to the sealing element. The driving end can drive the connecting end to move closer to or away from the pressure-receiving element under the action of external force. After the connecting end moves closer to the pressure-receiving element, the pressing element 32 can press against the pressure-receiving element to drive the sealing element to move downward.

[0030] The blending cup 40 is equipped with a feeding port, through which ingredients can be added to the blending cup 40 of the blender. When processing ingredients, the blending cup 40 of the blender can be placed below the processing chamber 22. Then, by external force, the driving end of the linkage rod 31 moves closer to the pressure-receiving component. As a result, the connecting end of the other end of the linkage rod 31 moves closer to the pressure-receiving component, so the top pressure component 32 connected to the connecting end moves closer to the pressure-receiving component. The top pressure component 32 can then press against the pressure-receiving component. After being pressed, the pressure-receiving component moves downward, thus driving the sealing component to move downward and seal the feeding port of the blending cup 40, achieving sound insulation and noise reduction at the feeding port of the blending cup 40.

[0031] Furthermore, in this embodiment, a cabinet door 21 is hinged to the cabinet body 20. The cabinet door 21 is used to rotate closer to or further away from the processing cavity 22. The cabinet door 21 is connected to the drive end and is used to drive the drive end to move during rotation, so as to drive the connection end closer to or further away from the pressure member.

[0032] Thus, when the sealing component moves downward, it can rotate away from the processing chamber 22 through the cabinet door 21. Therefore, the cabinet door 21 can pull the driving end of the linkage rod 31 away from the pressure-bearing component. As a result, the connecting end of the linkage rod 31 can move away from the pressure-bearing component, and the top pressure component 32 connected to the connecting end can move away from the pressure-bearing component. The pressure-bearing component loses the force of the top pressure component 32 and can move upward.

[0033] When performing the sealing action, the cabinet door 21 can be rotated close to the processing chamber 22. Thus, the cabinet door 21 can push the driving end of the linkage rod 31 close to the pressure-bearing component. Therefore, the connecting end of the linkage rod 31 can be close to the pressure-bearing component. The pressure-bearing component 32 connected to the connecting end can press against the pressure-bearing component. The pressure-bearing component can drive the sealing component to move downward to complete the sealing and achieve sound insulation and noise reduction.

[0034] Furthermore, in this embodiment, a movable cavity can be provided inside the top of the cabinet 20. The aforementioned linkage rod 31, pressing member 32, and other linkage mechanisms can be installed inside the movable cavity. The driving end of the linkage rod 31 can extend out of the movable cavity, facilitating connection with the cabinet door 21 or manual pushing. When using a drive structure to push and pull the linkage rod 31, the drive structure can be installed inside the movable cavity; the specific choice depends on actual needs.

[0035] Furthermore, a pressing slope 321 can be provided on the pressing member 32, and a corresponding pressing slope is provided on the pressing member. The pressing slope 321 and the pressing slope are in sliding fit. Based on this structure, when the pressing member 32 moves close to the pressing member, the pressing slope 321 on the pressing member 32 can decompose the lateral thrust into a downward pressing force, driving the pressing member to move downward.

[0036] Of course, an arc surface or a spherical surface can also be selected on the pressing component 32 to realize the pressing action on the pressure-bearing component, and the force can also be decomposed.

[0037] Furthermore, to ensure balanced force distribution on the pressure-bearing component, a top-pressing component 32 can be positioned around the pressure-bearing component, with top-pressing inclined surfaces 321 on both sides of the top-pressing component 32. Pressure-bearing rods 331 are provided on both sides of the pressure-bearing component, each with a pressure-bearing inclined surface. Based on this structure, when the connecting end of the linkage rod 31 moves close to the pressure-bearing component, both sides of the top-pressing component 32 can simultaneously approach the pressure-bearing rods 331 of the pressure-bearing component. Subsequently, the top-pressing inclined surfaces 321 on both sides of the top-pressing component 32 can simultaneously slide and engage with the pressure-bearing inclined surfaces on both sides of the pressure-bearing component, meaning both sides of the pressure-bearing component can move downwards under pressure, ensuring a smooth downward movement of the sealing component.

[0038] More specifically, the aforementioned pressure-bearing component is equipped with a collar 332, which is fitted over the sealing component and can be connected to it; both sides of the collar 332 are equipped with pressure rods 331. Based on this structure, the sealing component and the pressure-bearing component can be assembled as a set, resulting in a smaller overall volume of the sealing component after assembly and a smaller space occupied by the through opening 23.

[0039] Furthermore, an assembly gap is formed between the outer wall of the sealing member and the inner wall of the collar 332. Based on this structure, an elastic component can be provided within the assembly gap. The elastic component can be compressed when the pressure-bearing member is under pressure; that is, when the pressure-bearing member is under top pressure, the elastic component can be compressed when the sealing member moves downward. Subsequently, when the sealing member resets, the top pressure member 32 moves away from the pressure-bearing member, and the pressure-bearing member is no longer restricted by the top pressure. The elastic component can then reset. At this time, the elastic stress provided by the elastic component can drive the pressure-bearing member to move upward, thereby causing the sealing member to move upward.

[0040] It should be noted that, in the absence of elastic components, the resetting of the pressure-bearing component can be achieved manually after the top pressure component 32 moves away from the pressure-bearing component, since the pressure-bearing component is not limited by top pressure.

[0041] Furthermore, a venting channel is specifically provided within the sealing component, with a vent hole at the top and an air inlet at the bottom. During processing, the food processor 40 may be heated or pressurized due to the high-speed rotation of the processing blade assembly. Therefore, during processing, the gas inside the food processor 40 can be discharged through the vent hole via the venting channel, achieving venting and pressure maintenance.

[0042] It should be noted that an exhaust cover can be placed on the top of the sealing component. The exhaust cover has multiple exhaust holes. Specifically, the exhaust cover can be attached to the top of the sealing component by means of a snap or thread assembly. The exhaust cover has multiple exhaust holes for venting. Since the exhaust cover is prone to blockage after long-term use, the exhaust holes on the exhaust cover facilitate the disassembly and cleaning of the exhaust cover.

[0043] Furthermore, a sealing strip can be installed in the exhaust channel. This sealing strip seals the air inlet. When air enters the air inlet, the sealing strip is pushed away from the air inlet by the gas pressure, thus opening the air inlet. Specifically, when the food is just beginning to be processed, the sealing strip can block the air inlet. At this time, the exhaust channel is not connected to the outside of the cabinet 20, preventing external impurities from entering through the exhaust port and causing contamination.

[0044] When the blender cup 40 starts to rotate at high speed and pressurize, the pressure inside the cup increases. The sealing plate can be pressed by the air pressure inside the blender cup 40 to open the air inlet. The gas inside the blender cup 40 can enter the exhaust channel through the air inlet and be guided to the exhaust port for venting. A certain pressure is required to expel the gas, so it can also play a role in maintaining pressure.

[0045] It should be noted that the aforementioned sealing sheet can be made of silicone or rubber materials, which are readily available in the prior art, for easy sealing. Furthermore, when the air pressure inside the blending cup 40 is released, the air pressure is insufficient to press against the sealing sheet, allowing it to fall back to its original position under its own gravity.

[0046] Furthermore, a sealing block can be fitted around the outer periphery of the sealing component. Specifically, the sealing block can seal the outer periphery of the feeding port when the sealing component is in place. In particular, during food processing, the sealing block at the bottom of the sealing component can seal the outer periphery of the feeding port, providing a seal around the feeding port and further reducing noise.

[0047] Furthermore, the multi-functional mixer also includes a connecting assembly, specifically including a first connector 54, a second connector 55, and a noise reduction component 56. The first connector 54 is connected to the bottom end of the heat dissipation base 53, and the second connector 55 is connected to the bottom wall of the mounting cavity. The first connector 54 and the second connector 55 are connected to connect the heat dissipation base 53 and the bottom wall of the mounting cavity and are spaced apart. The noise reduction component 56 is clamped between the heat dissipation base 53 and the bottom wall of the mounting cavity.

[0048] The first connector 54 of the heat sink base 53 can be connected to the second connector 55 on the bottom wall of the mounting cavity of the base 10. After the first connector 54 and the second connector 55 are connected, the heat sink base 53 can be spaced apart on the bottom wall of the mounting cavity, that is, the heat sink base 53 can be suspended on the bottom wall of the mounting cavity. In order to prevent the heat sink base 53 from shaking after assembly, the heat sink base 53 and the bottom wall of the mounting cavity can not be in direct contact, but can be suspended and supported by multiple noise reduction components 56.

[0049] In addition, since the heat sink base 53 used to assemble the cooling fan is suspended from the bottom wall of the mounting cavity by multiple noise reduction components 56, during operation, the heat sink base 53 contacts the bottom wall of the mounting cavity through the noise reduction components 56, reducing the noise caused by the impact between the connecting parts, and the noise reduction effect is better.

[0050] Furthermore, a heat dissipation duct can be provided on the heat dissipation base 53, surrounding the heat dissipation cavity 531. One end of the heat dissipation duct extends into the heat dissipation cavity 531, and the other end extends into the air outlet 11. Based on this structure, when the airflow is discharged from the heat dissipation cavity 531, if the heat dissipation cavity 531 is connected to the air outlet 11, that is, the heat dissipation cavity 531 is directly connected to the external environment, the operating noise of the cooling fan in the heat dissipation cavity 531 will be directly discharged through the air outlet 11, and the noise reduction effect will be relatively poor. Therefore, in this embodiment, when the airflow is discharged, the airflow can be discharged in a ring around the outside of the heat dissipation cavity 531 through the heat dissipation duct, that is, the airflow is discharged to the air outlet 11 in a swirling manner, reducing the noise of the airflow discharge.

[0051] Furthermore, multiple first air guide holes 533 can be provided on the bottom wall of the heat dissipation base 53, and multiple second air guide holes 534 can be provided on the top wall of the heat dissipation base 53. The multiple first air guide holes 533 and multiple second air guide holes 534 are correspondingly arranged and connected, and the first air guide holes 533 and second air guide holes 534 are staggered from the heat dissipation air duct 532 and the heat dissipation cavity 531. Based on this structure, when airflow is introduced, the introduced gas can be introduced through the air inlet. Part of the airflow exiting the air inlet can directly enter the mounting cavity, and the other part can be introduced through the first air guide holes 533 and then exited through the second air guide holes 534. The airflow is introduced in two parts, realizing the airflow circulation introduction, which makes the airflow introduction more dispersed and the noise reduction effect better.

[0052] Furthermore, in this embodiment, the noise reduction component 56 includes a clamping pad, both ends of which are provided with through posts, and corresponding through holes are provided on the bottom wall of the mounting cavity. When the noise reduction component 56 is assembled with the bottom wall of the mounting cavity, the through posts at the bottom end of the clamping pad can pass through the through holes in the bottom wall of the mounting cavity, so that the clamping pad is clamped between the heat dissipation base 53 and the bottom wall of the mounting cavity. That is, the clamping pad can be supported on the bottom end of the heat dissipation base 53. The clamping pad can be made of materials such as silicone pads or rubber pads to reduce the impact between the heat dissipation base 53 and the bottom wall of the mounting cavity, thereby achieving noise reduction.

[0053] Of course, the noise reduction component 56 can also be supported by materials such as sound insulation cotton or supporting sponge in the prior art. Based on this structure, the assembly between the noise reduction component 56 and the bottom wall of the mounting cavity can also be connected by adhesive bonding.

[0054] Furthermore, in this embodiment, the first connector 54 is a connecting post, and the second connector 55 is a through sleeve. When assembling the heat dissipation base 53 with the bottom wall of the mounting cavity, the heat dissipation base 53 can be inserted into the through sleeve through the connecting post. Specifically, the connecting post can be integrally formed on the heat dissipation base 53, and a first sound insulation pad is fitted on the outside of the connecting post. The first sound insulation pad can also be made of silicone or rubber sleeves, etc. That is, after the connecting post and the bottom wall through sleeve of the mounting cavity are assembled, the two can be separated by the first sound insulation pad, and sound insulation and noise reduction are achieved at the assembly gap.

[0055] Furthermore, the bottom end of the first sound insulation pad protrudes through the through sleeve. The portion of the first sound insulation pad protruding through the bottom end of the through sleeve may be provided with a limiting step. The limiting step abuts against the bottom wall of the through sleeve. In this way, when the connecting column of the heat dissipation base 53 moves up and down relative to the through sleeve, the limiting step can abut against the bottom end of the through sleeve, which can reduce the noise caused by the up and down movement.

[0056] Furthermore, a baffle can be provided at the air outlet 11, with multiple guide ports 111 on the baffle; the heat dissipation cavity 531 is connected to the lower part of the baffle. In this way, when the airflow is discharged from the heat dissipation cavity 531, it can enter the lower part of the baffle at the air outlet 11, and then be discharged upward through the multiple guide ports 111 on the baffle before being discharged to the air outlet 11. That is, the airflow at the air outlet 11 is also a meandering flow, which can also slow down the gas flow rate and reduce noise.

[0057] In addition to the above-mentioned heat dissipation duct structure in the heat dissipation base 53, multiple through holes 535 can be provided at the outlet end of the heat dissipation duct to disperse the airflow of the heat dissipation cavity 531 into the air outlet 11, thereby achieving further noise reduction.

[0058] Furthermore, in this embodiment, a top cover 59 may be provided at the top of the base 10. The top cover 59 covers the top of the mounting cavity. After the top cover 59 covers the top of the mounting cavity, the rotating shaft of the motor can extend out from the top cover 59.

[0059] To facilitate the assembly of the top cover 59 with the mounting cavity, a positioning post can be provided at the bottom of the top cover 59, and a positioning hole is provided at the top of the soundproof cover 52. The positioning post is inserted into the positioning hole. A second soundproof pad 591 is clamped between the positioning post and the positioning hole. In this way, the assembly of the top cover 59 and the soundproof cover 52 can be achieved by the insertion and cooperation of the positioning post and the positioning hole. Then, the second soundproof pad 591 is clamped between the positioning post and the positioning hole. The second soundproof pad 591 can reduce the friction between the positioning post and the positioning hole, thereby reducing the noise caused by assembly friction after assembly.

[0060] Similarly, the second sound insulation pad 591 mentioned above can also be a silicone pad or a rubber pad as used in the prior art. In addition, the positioning post and the connecting post mentioned above can both be implemented using existing structures such as screws, bolts, or pins.

[0061] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
