Description

Technical Field

[0001] This utility model belongs to the technical field of food processing machines, specifically relating to a high-speed blender. Background Technology

[0002] With the continuous development of the social economy and the significant improvement of people's living standards, consumers have increasingly stringent requirements for the performance of kitchen appliances, including higher requirements for the noise generated during product operation. As a common kitchen appliance, blenders generate noise from their internal drive motors and blade components when operating at high speeds, which can quickly spread through the air to the surrounding environment, causing disturbance to users and those nearby.

[0003] Currently, the market employs a series of conventional solutions to address the noise problem of high-speed blenders, primarily including the use of silencers, sound-absorbing cotton, soundproof covers, or double-layered blending cups. Silencers mainly weaken sound propagation by altering airflow channels or utilizing acoustic principles; sound-absorbing cotton absorbs some sound wave energy through its porous structure; soundproof covers reduce noise leakage by blocking the sound propagation path; and double-layered cups utilize the air layer between the two cup walls to provide some sound insulation. However, while these existing solutions can all achieve a certain degree of noise reduction, they cannot effectively isolate sound from propagating into the environment. The noise generated by the blender during operation remains quite noticeable, failing to meet consumers' demands for a low-noise environment. Therefore, developing a high-speed blender with significantly improved noise reduction capabilities is of significant practical importance. Utility Model Content

[0004] In order to overcome at least one of the defects mentioned above in the prior art, this utility model provides a blender to solve the problem that the existing noise reduction schemes of blenders cannot completely isolate sound from propagating into the environment and have poor noise reduction effect. Through a unique structural design, it achieves double-sealed noise reduction and significantly reduces the noise level of the blender during operation.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A blender includes: a base, the base having a closed first soundproof cavity; a mixing cup assembly, including a mixing cup and a base, the mixing cup being disposed within the first soundproof cavity, the mixing cup having a mixing chamber therein; the base being disposed at the bottom of the mixing cup and located within the first soundproof cavity, the base having a closed second soundproof cavity therein; a drive motor, disposed within the second soundproof cavity; and a blade assembly, disposed within the mixing chamber, the blade assembly being drively connected to the drive motor, the rotating shaft of the blade assembly being coaxially arranged with the motor shaft of the drive motor.

[0007] As an optional implementation, the mixing cup assembly further includes a cup lid, which covers the mixing cup and has a communication port communicating with the mixing chamber; the top of the base is provided with an installation port; the blender further includes a water supply assembly and a valve assembly; the valve assembly includes a flow guide cover and a first sealing ring, the flow guide cover is inserted into the installation port and the communication port, the flow guide cover has a water supply channel communicating with the mixing chamber, the first sealing ring is sleeved on the flow guide cover, and the outer wall of the first sealing ring abuts against the installation port; the water supply assembly includes a water tank and a water pump, both of which are located on the base, and the water pump is used to deliver water from the water tank to the inlet of the water supply channel.

[0008] As an optional implementation, the outer wall of the first sealing ring is provided with a third lip, which abuts against the inner wall of the mounting port.

[0009] As an optional implementation, the outer wall of the first sealing ring is provided with a first lip, which abuts against the inner wall of the communication opening.

[0010] As an optional implementation, the outer wall of the first sealing ring is provided with a second lip, the second lip abutting against the inner wall of the mounting port, the second lip being located above the first lip and below the third lip.

[0011] As an optional implementation, the water supply assembly includes a drain pipe, an inlet cylinder protruding outward from the mounting port, the drain pipe being connected to the water tank, one end of the drain pipe being sleeved on the inlet cylinder, the water pump being used to discharge liquid from the water tank to the drain pipe, and a second lip being located between the inlet cylinder and the inlet of the water supply channel, the second lip being able to guide water from the inlet cylinder to the inlet of the water supply channel.

[0012] As an optional implementation, the second lip is provided with a flow guiding slope, which slopes downward from the water inlet cylinder toward the water inlet of the water supply channel.

[0013] As an optional implementation, the second lip is higher than the lowest point of the water inlet of the water supply channel.

[0014] As an optional implementation, the base is provided with a first electrical connector, and the first soundproof cavity is provided with a second electrical connector. When the stirring cup assembly is installed laterally into the first soundproof cavity, the first electrical connector is laterally connected to the second electrical connector.

[0015] As an optional implementation, the base includes a base body and a rotating door, the rotating door being rotatably connected to the base body and capable of rotating relative to the base body between an open position and a closed position; when the rotating door is in the closed position, the first sound insulation cavity is formed between the base body and the rotating door.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

By enclosing the drive motor within this cavity, the path for noise generated during motor operation to directly propagate outwards is effectively cut off. Simultaneously, the entire blending cup assembly is enclosed within a first sound-insulating cavity, further preventing sound from spreading from the blending cup assembly into the surrounding environment. This double-sealed structure, utilizing both the first and second sound-insulating cavities, significantly improves the blender's noise reduction capabilities, substantially lowering the noise level during operation and creating a quieter and more comfortable user environment. Secondly, the blade assembly's rotating shaft and the drive motor's motor shaft are coaxially aligned. This design ensures smoother power transmission and reduces vibration and noise caused by deviations and friction between transmission components. Attached Figure Description

[0032] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0033] Please see Figures 1 to 6 This application provides a blender, including a base 1, a mixing cup assembly 4, a drive motor 3, and a blade assembly 5; the base 1 can form a closed first soundproof cavity 11; the mixing cup assembly 4 includes a mixing cup 41 and a base 43, the mixing cup 41 is disposed in the first soundproof cavity 11, the mixing cup 41 is provided with a mixing chamber 411, the base 43 is disposed at the bottom of the mixing cup 41 and located in the first soundproof cavity 11, the base 43 is formed in a closed second soundproof cavity 431; the drive motor 3 is disposed in the second soundproof cavity 431; the blade assembly 5 is disposed in the mixing chamber 411, the blade assembly 5 and the drive motor 3 are connected by transmission, and the rotating shaft of the blade assembly 5 and the motor shaft 31 of the drive motor 3 are coaxially arranged.

[0034] The blender provided in this application embodiment has two aspects. First, the base 43 is designed without an air duct to form a second sound insulation cavity 431. By enclosing the drive motor 3 within the second sound insulation cavity 431, the path for noise generated by the drive motor 3 during operation to directly propagate outward is effectively cut off. Simultaneously, the mixing cup assembly 4 is entirely enclosed within the first sound insulation cavity 11, further preventing sound from propagating from the mixing cup assembly 4 into the surrounding environment. The double-enclosed structure formed by the first and second sound insulation cavities 11 and 431 greatly improves the noise reduction capability of the blender, significantly reducing the noise level during operation and creating a quieter and more comfortable user environment. Second, the rotating shaft of the blade assembly 5 and the motor shaft 31 of the drive motor 3 are coaxially arranged. This design makes power transmission smoother and reduces vibration and noise caused by deviations and friction between transmission components.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in one embodiment, the mixing cup assembly 4 further includes a cup lid 42, which covers the mixing cup 41 and is disposed at a communication port 421 communicating with the mixing chamber 411; the top of the base 1 is provided with an installation port 14; the blender further includes a water supply assembly 6 and a valve assembly 7; the valve assembly 7 includes a guide cover 71 and a first sealing ring 72, the guide cover 71 is inserted into the installation port 14 and the communication port 421, the guide cover 71 is provided with a water supply channel 711 communicating with the mixing chamber 411, the first sealing ring 72 is sleeved on the guide cover 71, and the outer wall of the first sealing ring 72 abuts against the installation port 14; the water supply assembly 6 includes a water tank 61 and a water pump 62, both of which are disposed on the base 1, and the water pump 62 is used to transport water in the water tank 61 to the inlet of the water supply channel 711. The first sealing ring 72 can prevent liquid leakage and also has a noise reduction effect. With this design, firstly, in the prior art, when a blender uses the timed cooking mode, water needs to be put into the mixing cup 41 in advance to mix with the ingredients, which causes some ingredients to soak in water for a long time. However, in this embodiment, by setting up an independent water supply component 6 and valve component 7, it is not necessary to put water into the mixing cup 41 in advance to contact with the ingredients during the timed cooking stage. Only when the timed cooking time is reached and the blender is started will the water pump 62 deliver the water in the water tank 61 to the mixing chamber 411 through the water supply channel 711 to mix with the ingredients. In this way, the ingredients will not deteriorate due to prolonged soaking in water, and the nutritional components of the ingredients can be preserved to the greatest extent, ensuring the quality and taste of the cooked food and providing users with a healthier and more delicious eating experience. Secondly, the first sealing ring 72 in the valve assembly 7 is fitted onto the guide cover 71, and its outer wall abuts against the mounting port 14 on the top of the base 1. This design creates a reliable sealing structure between the guide cover 71 and the mounting port 14 of the base 1. During water supply, water in the water tank 61 enters the water supply channel 711 and flows to the stirring chamber 411 under the action of the water pump 62. The first sealing ring 72 can effectively prevent water from leaking out from the connection between the guide cover 71 and the mounting port 14, avoiding damage to the internal circuits and components of the blender that may be caused by liquid leakage. This improves the safety and reliability of the blender and extends its service life. At the same time, it also prevents water from leaking into the surrounding environment, keeping the environment clean. Thirdly, in addition to its sealing function, the first sealing ring 72 also plays a role in noise reduction. The first sealing ring 72, fitted onto the guide cover 71 and abutting against the mounting port 14, can buffer and absorb the vibration and noise generated by the operation of the equipment, reducing the transmission of noise from the mounting port 14 to the surrounding environment.

[0036] like Figure 1 and Figure 2As shown, in one embodiment, the outer wall of the first sealing ring 72 is provided with a third lip 723, which abuts against the inner wall of the mounting port 14. Thus, firstly, the presence of the third lip 723 is equivalent to adding an extra sealing layer to the original seal. It can fit more tightly against the inner wall of the mounting port 14. Even if there is slight sealing insufficiency in other areas, the third lip 723 can effectively block liquid from passing through, thereby completely eliminating the possibility of water in the water tank 61 leaking from the connection between the guide cover 71 and the mounting port 14 during transportation. This ensures the safety of the internal circuitry and components of the blender, avoids short circuits, damage, and other malfunctions caused by liquid leakage, and greatly improves the reliability and stability of the blender. Secondly, the third lip 723 abuts against the inner wall of the mounting port 14, which can buffer and absorb vibration during transmission. When vibration is transmitted from the guide cover 71 to the first sealing ring 72, the third lip 723 can consume some vibration energy through its own elastic deformation, reducing the transmission of vibration to the base 1 and other components, thereby reducing the noise generated by vibration. Compared with the structure without the third lip 723, this embodiment can significantly reduce the noise level of the blender during operation, creating a quieter and more comfortable operating environment for users. Thirdly, the mounting port 14 is an important channel connecting the water supply system and the interior of the base 1, and it is also one of the parts where noise is easily leaked. The third lip 723, through its tight fit and elastic deformation, fills the tiny gaps at the mounting port 14, preventing sound waves from propagating through these gaps, thereby improving the overall sound insulation effect.

[0037] like Figure 1 and Figure 2As shown, in one embodiment, the outer wall of the first sealing ring 72 is provided with a first lip 721, which abuts against the inner wall of the connecting port 421. This arrangement, firstly, with the first lip 721 on the outer wall of the first sealing ring 72 abutting against the inner wall of the connecting port 421, together with the previously mentioned third lip 723 (abutting against the inner wall of the mounting port 14), forms a multi-layer sealing structure. The first lip 721, due to its elastic deformation capability, can tightly fit against the inner wall of the connecting port 421, effectively preventing water from leaking from the connection between the guide cap 71 and the connecting port 421 to the outside of the mixing cup 41. This avoids damage to the internal circuitry, motor, and other components of the blender due to liquid leakage, ensuring the normal operation of the blender, and also prevents water from splashing into the surrounding environment, keeping the usage area clean. Secondly, when vibration is transmitted to the first sealing ring 72, the first lip 721 absorbs some of the vibration energy through its own elastic deformation, reducing the transmission of vibration to the mixing cup 41 and other components. As a result, the overall noise generated by the blender is reduced, creating a quieter operating environment for the user. Thirdly, the mixing chamber 411 is one of the main noise-generating areas in the blender. The food is pulverized under the action of the high-speed rotating blades, which generates strong mechanical vibration and airflow disturbance, thus causing noise. The first lip 721 abuts against the inner wall of the connecting port 421 and fits tightly against the connection between the mixing cup 41 and the guide cover 71, directly blocking the path of noise in the mixing chamber 411 to the outside through the connecting port 421. Furthermore, its elastic material can undergo slight deformation when impacted by sound waves, converting some of the sound wave energy into its own elastic potential energy, thereby weakening the intensity of the noise.

[0038] like Figure 1 and Figure 2As shown, in one embodiment, the outer wall of the first sealing ring 72 is provided with a second lip 722, the second lip 722 abuts against the inner wall of the mounting port 14, and the second lip 722 is located above the first lip 721 and below the third lip 723. With this configuration, firstly, a second lip 722 is provided on the outer wall of the first sealing ring 72, and it abuts against the inner wall of the mounting port 14. Together with the first lip 721 and the third lip 723, a multi-layer three-dimensional sealing structure is constructed. The second lip 722 is located above the first lip 721 and below the third lip 723, filling the sealing gap between the two. This ensures that no matter which direction the liquid attempts to leak, it will be blocked by at least one lip. This all-round sealing design greatly improves the reliability of the seal, effectively prevents water leakage from the connection between the guide cover 71 and the mounting port 14 and the connecting port 421, ensures the safety of the internal circuits and components of the blender, avoids short circuits, damage and other malfunctions caused by liquid leakage, and extends the service life of the equipment. Secondly, when vibration is transmitted to the first sealing ring 72, each lip can absorb and disperse a portion of the vibration energy. The second lip 722 is located in the middle position and can receive vibrations from above and below and disperse them into the surrounding structure, reducing the transmission of vibration to the mixing cup 41 and other parts of the base 1. This multi-layered buffering effect significantly reduces the noise generated by the blender as a whole, creating a quieter and more comfortable user environment.

[0039] like Figure 1 and Figure 2 As shown, in one embodiment, the first lip 721, the second lip 722, and the third lip 723 cooperate and work together to form a complete and effective noise isolation system. They block and attenuate the noise generated during the operation of the blender from different positions and angles, greatly reducing the noise intensity transmitted from the equipment to the external environment.

[0040] like Figure 1 and Figure 2As shown, in one embodiment, the water supply assembly 6 includes a drain pipe 63, an inlet cylinder 15 protruding outward from the mounting port 14, the drain pipe 63 and the water tank 61 are connected, one end of the drain pipe 63 is sleeved on the inlet cylinder 15, the water pump 62 is used to discharge the liquid from the water tank 61 to the drain pipe 63, and the second lip 722 is located between the inlet cylinder 15 and the inlet of the water supply channel 711. The second lip 722 can guide water from the inlet cylinder 15 to the inlet of the water supply channel 711. Thus, the second lip 722 not only seals the water, but also guides water from the inlet cylinder 15 to the inlet of the water supply channel 711. During the operation of the blender, the water pump 62 draws water from the water tank 61 and pumps it into the drain pipe 63. After the water reaches the inlet cylinder 15, the second lip 722 can guide the water flow smoothly into the inlet of the water supply channel 711 in a predetermined direction, ensuring that the water flow can enter the water supply channel 711 efficiently and smoothly, providing a stable guarantee for the subsequent water supply process.

[0041] like Figure 1 and Figure 2 As shown, in one embodiment, the second lip 722 is provided with a guide slope, which slopes downward from the water inlet cylinder 15 toward the water inlet of the water supply channel 711. This inclined design provides a clear and smooth flow path for the water. When water in the water tank 61 enters the water inlet cylinder 15 under the action of the water pump 62, it flows naturally and unobstructed along the guide slope to the water inlet of the water supply channel 711.

[0042] In one embodiment, the flow guide cover 71 of the valve assembly 7 is detachably inserted into the mounting port 14 and the communication port 421. When the user needs to remove the flow guide cover 71 for cleaning, replacement, or other operations, if there is water residue at the second lip 722, it is easy to carry water out during the removal process, splashing onto the user or the surrounding countertop, causing inconvenience and trouble for the user. To solve the above problem, in one embodiment, the second lip 722 is higher than the lowest point of the water inlet of the water supply channel 711. In this way, when the blender completes the water supply operation and the water pump 62 stops working, the water remaining near the second lip 722 will automatically flow to the water inlet of the water supply channel 711 under the action of gravity, and then be discharged into the mixing cup 41, fundamentally avoiding water accumulation at the second lip 722 and reducing the possibility of liquid residue.

[0043] like Figure 1 and Figure 2 As shown, in one embodiment, the outer wall of the first sealing ring 72 is provided with a first flow guide opening 724, which is used to allow liquid to flow from the water inlet cylinder 15 to the water inlet of the water supply channel 711.

[0044] like Figure 1 and Figure 2As shown, in one embodiment, the outlet of the water supply channel 711 faces the stirring chamber 411, and the bottom of the first sealing ring 72 is provided with a second flow guide opening 725, which is used to allow liquid to flow from the outlet of the water supply channel 711 into the stirring chamber 411.

[0045] like Figure 1 and Figure 2 As shown, in one embodiment, the water supply component 6 further includes a water inlet pipe 64, which is connected to the water tank 61 and is used to replenish water to the water tank 61.

[0046] Water pump 62 will generate some noise during operation, such as Figure 1 As shown, in one embodiment, the water pump 62 is located at the bottom of the base 1, that is, the water pump 62 is located on the side of the base 1 away from the mounting port 14, so as to isolate the propagation path of noise to a certain extent.

[0047] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, the base 43 is provided with a first electrical connector 432, and the first soundproof cavity 11 is provided with a second electrical connector 16. When the first electrical connector 432 and the second electrical connector 16 are connected, the drive motor 3 can be activated to achieve the stirring function. When the stirring cup assembly 4 is installed laterally into the first soundproof cavity 11, the first electrical connector 432 is connected laterally to the second electrical connector 16. In traditional blender designs, the electrical connectors may be connected vertically, which occupies extra space in the vertical direction, resulting in an increase in the overall height of the blender. However, in this embodiment, the stirring cup assembly 4 is installed laterally into the first soundproof cavity 11, and the first electrical connector 432 is connected laterally to the second electrical connector 16, avoiding the increase in size in the vertical direction due to the electrical connector connection, thereby effectively reducing the overall height of the blender.

[0048] like Figure 1 , Figure 5 and Figure 6As shown, in one embodiment, the base 1 includes a base body 12 and a rotating door 13. The rotating door 13 is rotatably connected to the base body 12 and can rotate relative to the base body 12 between an open position and a closed position. When the rotating door 13 is in the open position, the mixing cup assembly 4 can be inserted laterally into the base body 12 and connected to the first electrical connector 432 and the second electrical connector 16. When the rotating door 13 is in the closed position, a first soundproof cavity 11 is formed between the base body 12 and the rotating door 13. Thus, in a first aspect, the design of the rotating door 13 makes the installation and removal of the mixing cup assembly 4 extremely simple. The user only needs to rotate the rotating door 13 to the open position to obtain a spacious and unobstructed operating space, and can easily push or pull the mixing cup assembly 4 laterally into or out of the base body 12. When it is necessary to clean the inside of the base 1, the user can open the rotating door 13 and directly wipe and clean the area around the base body 12 and the mixing cup assembly 4 without disassembling too many parts. Furthermore, when the mixing cup assembly 4 is installed horizontally, the first electrical connector 432 and the second electrical connector 16 are mated in the same direction. This mating method makes it easier to achieve precise positioning and stable connection, ensuring that the two electrical connectors can be accurately inserted together, reducing problems such as poor electrical contact and short circuits caused by inaccurate connection. In addition, when the rotating door 13 is in the closed position, the first sound insulation cavity 11 is formed between the base body 12 and the rotating door 13, effectively sealing the mixing cup assembly 4.

[0049] In one embodiment, the first electrical connector 432 and the second electrical connector 16 described above are a pair of couplers.

[0050] like Figure 1 As shown, in one embodiment, a second sealing ring 2 is provided inside the base body 12. When the rotating door 13 is in the closed position, the second sealing ring 2 abuts against the inner side of the rotating door 13.

[0051] In summary, the blender disclosed in this utility model can bring at least the following beneficial technical effects:

[0052] (1) The base 43 has no air duct design to form a second sound insulation cavity 431. By enclosing the drive motor 3 in the second sound insulation cavity 431, the path of the noise generated by the drive motor 3 during operation is effectively cut off to the outside.

[0053] (2) The mixing cup assembly 4 is completely enclosed in the first sound insulation cavity 11, which further prevents sound from spreading from the mixing cup assembly 4 to the surrounding environment. The double-enclosed structure formed by the first sound insulation cavity 11 and the second sound insulation cavity 431 greatly improves the noise reduction capability of the blender and significantly reduces the noise level of the blender during operation.

[0054] (3) The rotating shaft of the blade assembly 5 and the motor shaft 31 of the drive motor 3 are coaxially arranged. This design makes the power transmission smoother and reduces the vibration and noise caused by the deviation and friction between the transmission components.

[0055] (4) The first lip 721, the second lip 722 and the third lip 723 work together to form a complete and effective noise isolation system. They block and attenuate the noise generated during the operation of the blender from different positions and angles, greatly reducing the noise intensity transmitted from the equipment to the external environment.

[0056] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
