Description

Technical Field

[0001] This utility model relates to the field of food processing machine technology, and in particular to a low-noise food processing machine. Background Technology

[0002] Existing food processing machines, such as juicers, are described in Chinese Utility Model Patent CN220087085U, entitled "Motor Air Inlet and Outlet Structure for a Juicer," with an authorization announcement date of November 24, 2023. This includes a main unit containing an air inlet channel, an air outlet channel, and a motor assembly. A portion of the motor assembly extends into the air inlet channel, and another portion extends into the air outlet channel. The motor assembly within the air inlet and outlet channels has a motor air inlet and an air outlet, respectively. The outer wall of the motor assembly between the air inlet and outlet channels is sealed to the air inlet or outlet channel. This juicer utilizes the sealed fit between the outer wall of the motor assembly and the air inlet channel, or between the outer wall of the motor assembly and the air outlet channel, to prevent communication between the air inlet and outlet channels and avoid mutual interference, thus significantly improving the heat dissipation effect of the motor assembly.

[0003] However, the juicer with the above structure still has the following shortcomings: (1) The main unit is equipped with a motor assembly and a speed reduction transmission module that are connected to each other. When the gears in the speed reduction transmission module mesh, they will generate a lot of noise. The shell of the main unit has limited noise blocking effect, so the product will still generate a lot of noise when it is in use. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a food processing machine with an added soundproof cover, which reduces the overall noise of the product during operation.

[0005] The purpose of this utility model is achieved as follows:

[0006] A low-noise food processing machine includes a main housing, within which a motor and a reduction gear transmission module are housed. The reduction gear transmission module includes an outer shell and a transmission gear assembly disposed within the outer shell. The motor is fixed to one end of the outer shell, and its drive shaft extends into the outer shell and is connected to the transmission gear assembly. The machine is characterized by also including a soundproof cover, which is fixed to the outer shell and partially encloses it. In this low-noise food processing machine, the soundproof cover, fixed to the outer shell of the reduction gear transmission assembly, effectively blocks noise generated during operation. Furthermore, the soundproof cover, in conjunction with the main housing, provides double sound insulation for the reduction gear transmission assembly, resulting in lower overall noise levels during operation.

[0007] The objective of this utility model can also be achieved by the following technical measures:

[0008] Specifically, it further includes a motor cover, the lower part of which is fixed to one end of the outer shell and covers the motor and another part of the outer shell. The soundproof cover is connected to one side of the motor cover. This allows the motor cover and the soundproof cover to cooperate and cover the motor and the speed reduction transmission components, which can effectively block the noise generated by the motor and the speed reduction transmission components during operation and can effectively reduce the overall noise of the product.

[0009] Furthermore, the soundproof cover and the motor cover are integrally formed, and the interior of the soundproof cover is connected to the interior of the motor cover; this facilitates the two working together to enclose the motor and the speed reduction transmission components, and the integrally formed soundproof cover and motor cover make it easy for the two to be manufactured together.

[0010] Specifically, it further includes a lower cover plate. The motor cover includes a hollow cover body and an upper cover plate. The hollow cover body is integrally formed with the sound insulation cover. The upper cover plate is fixed at the upper opening of the hollow cover body, and the lower cover plate is fixed at the lower opening of the hollow cover body and the lower opening of the sound insulation cover, so that the lower cover plate, motor cover, sound insulation cover, reduction transmission module and motor constitute an integrated drive module. On the one hand, this integrated drive module makes the structure between the components compact, which is conducive to reducing the overall volume of the drive module. At the same time, this integrated drive module can be installed on different host housings, and its applicability is wide. On the other hand, the lower cover plate, hollow cover body and upper cover plate work together to fully enclose the motor and reduction transmission components, and its sound insulation effect is good.

[0011] Specifically, the outer casing is provided with several hollow connecting columns around its perimeter. The soundproof cover encloses several hollow connecting columns and a portion of the outer casing. The lower cover plate has connecting through holes corresponding to the positions of the hollow connecting columns. A connecting screw passes through the connecting through holes, hollow connecting columns, and soundproof cover from bottom to top and is then fixedly connected to the inner wall of the main unit casing. This design achieves both the installation and fixation of the lower cover plate at the lower opening of the soundproof cover and the outer casing inside the soundproof cover, as well as the installation and fixation of the drive module inside the main unit casing. The design is ingenious and the implementation effect is good.

[0012] Specifically, it further includes a circuit board, and a mounting box is provided on the outer wall of the motor cover. One side of the mounting box is provided with a placement space, and the other side of the mounting box is provided with a drainage channel. The circuit board is placed in the placement space and the motor is electrically connected to the circuit board. The mounting box can serve as a mounting carrier for the circuit board and also play a role in drainage. At the same time, the circuit board and the drainage channel can each perform their own functions independently and stably.

[0013] Specifically, it further includes a trigger rod and an elastic element. A water receiving box extends outward from the middle of the trigger rod. The water receiving box is movably snapped onto the upper end of the mounting box. The elastic element is fitted under the trigger rod, with its two ends abutting against the upper end of the mounting box and the bottom of the water receiving box, respectively. A safety switch is also provided on the circuit board. The bottom end of the trigger rod extends into the mounting space and is close to the safety switch. A hollow water-guiding column is provided on the water receiving box, with one end of the hollow water-guiding column extending into the drainage channel. The trigger rod and the water receiving box are movably mounted on the upper part of the mounting box, so that the circuit board, trigger rod, water receiving box, and mounting box are connected together. The structure between the components is compact, which helps to reduce the overall size of the product. Furthermore, the trigger rod is stably mounted on the mounting box through the water receiving box, thereby stably triggering the micro switch on the circuit board. Water is discharged outside the main unit housing through the water-guiding box and the drainage channel, so that the trigger rod and the water-guiding box can independently and stably perform their own functions.

[0014] Specifically, the main unit housing has a main unit air inlet and a main unit air outlet on its outer periphery, the motor has a motor air inlet and a motor air outlet, the hollow cover has an air inlet cavity and an air outlet cavity, and the upper part of the air inlet cavity is connected to the upper part of the air outlet cavity. The air inlet cavity surrounds the outer periphery of the motor, and the motor air inlet is located at the lower part of the air inlet cavity. The lower cover plate has a through-section, and the through-section is connected to the main unit air inlet and the lower opening of the air inlet cavity respectively. The motor air outlet is located at the upper part of the air inlet cavity, and the lower opening of the air outlet cavity is connected to the main unit air outlet. This allows external air to enter the drive module sequentially through the main unit air inlet and the through-section, and then sequentially enter the motor through the motor air inlet for heat absorption. The hot air discharged from the motor air outlet sequentially passes through the upper part of the air inlet cavity and the air outlet cavity before being discharged through the main unit air outlet. The overall exhaust path is relatively short, which is beneficial to improving the exhaust heat dissipation effect.

[0015] The beneficial effects of this utility model are as follows:

[0016] This low-noise food processor has a soundproof cover fixed to the outer shell of the speed reduction transmission component. It can effectively block the noise generated by the speed reduction transmission component during operation. Moreover, the soundproof cover, together with the main body shell, achieves double sound insulation for the speed reduction transmission component, resulting in lower overall noise during product operation.

[0017] On the one hand, this integrated drive module makes the structure between the components compact, which is conducive to reducing the overall size of the drive module. At the same time, this integrated drive module can be installed on different host housings, making it widely applicable. On the other hand, the lower cover, hollow cover and upper cover work together to fully enclose the motor and reduction transmission components, which has a good sound insulation effect.

[0018] The trigger rod, together with the water receiving box, is movably mounted on the upper part of the mounting box, connecting the circuit board, trigger rod, water receiving box, and mounting box together. The compact structure of each component helps to reduce the overall size of the product. Furthermore, the trigger rod is stably mounted on the mounting box through the water receiving box, thereby stably triggering the micro switch on the circuit board. Water is discharged outside the main unit housing through the water inlet box and drainage channel, enabling the trigger rod and water inlet box to independently and stably perform their respective functions.
