Description

Technical Field

[0001] This utility model specifically relates to a drive module and a food processing machine. Background Technology

[0002] Existing food processing machines, as seen in Chinese Utility Model Patent CN214014066U, entitled "Motor Heat Dissipation Structure for a Food Processor," authorized on August 20, 2021, include a main housing and a motor housed within the housing. The motor has a motor shaft extending from its first end. It also includes an isolation cover, with the motor shaft extending in the opposite direction from its second end. A cooling fan is mounted on the second end of the motor shaft. The isolation cover covers the cooling fan and is connected to the motor, with an air outlet on the cover. This invention achieves the following: air flows out of the motor after passing through its interior, facilitating heat dissipation; the isolation cover is integrated with the motor, simplifying assembly; it ensures effective heat dissipation; and it disperses the hot air exhausted from the outlet, further aiding in heat dissipation.

[0003] However, the above-mentioned food processing machine still has the following shortcomings: (1) The main body housing is equipped with a motor, air guide, speed reduction transmission component and circuit board connected to the motor. However, the motor, air guide, speed reduction transmission component and circuit board are installed and fixed in the main body housing through different structures, which makes the overall installation operation of the product more complicated and time-consuming. In addition, the distance between the circuit board and the motor, air guide and speed reduction transmission component is far, which makes the overall structure of the product not compact and the overall volume larger. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a drive module in which the motor, the speed reduction transmission component, the motor cover and the circuit board can be formed into an integral module, which facilitates the installation and fixation of this integral module on an external carrier, has wide applicability, and the components of this integral module have a compact structure, which is conducive to reducing the overall size of the drive module.

[0005] Another objective of this invention is to provide a food processing machine that includes the aforementioned drive module. The components of this integrated module are compact and the overall volume is small, which allows the overall volume of the main unit housing to be made smaller.

[0006] The purpose of this utility model is achieved as follows: A drive module includes a motor, a reduction gear assembly, and a circuit board. The motor is fixed to the reduction gear assembly, and the motor's drive shaft is connected to the reduction gear assembly. The module further includes a motor cover, which is fixed to the reduction gear assembly and encloses the motor. The motor cover also has a circuit board mounting portion, and the circuit board is fixed to the circuit board mounting portion. This drive module, by fixing the circuit board to the motor cover and the motor cover and motor to the reduction gear assembly, allows the motor, reduction gear assembly, motor cover, and circuit board to form an integrated module. This facilitates the installation and fixation of this integrated module on an external carrier. Furthermore, this integrated module is applicable to various external carriers, has wide applicability, and the compact structure of its components helps reduce the overall size of the drive module and the external carrier.

[0007] The objective of this utility model can also be achieved by the following technical measures: Specifically, the motor cover includes a hollow cover body and a top cover plate. The top cover plate covers the upper opening of the hollow cover body. The hollow cover body is fitted around the outer periphery of the motor, and the lower part of the hollow cover body is fixed to the reduction gear transmission assembly. A drainage box extends from the outer periphery of the hollow cover body. A circuit board mounting slot is opened on one side of the drainage box, which constitutes the circuit board mounting part. The hollow cover body plays a drainage role through the drainage box, and at the same time, the drainage box can also serve as a mounting carrier for the circuit board. Its design is ingenious and its implementation effect is good.

[0008] Specifically, the drainage box includes a partition plate, with a circuit board mounting groove on one side of the partition plate and a drainage channel on the other side of the partition plate; so that the circuit board and the drainage channel are located on opposite sides of the partition plate, which is conducive to the circuit board and the drainage channel independently and stably performing their respective functions.

[0009] Specifically, one side of the partition plate extends outward to form an outer wall, which together with the partition plate forms the circuit board mounting groove. Guide slots are provided on both sides of the outer wall, and the circuit board is inserted into the guide slots on both sides, with an isolation space between the circuit board and the partition plate. The isolation space ensures that the circuit board can work stably, and the guide slots play a good guiding and positioning role for the installation of the circuit board in the placement space, which facilitates the installation operation of the circuit board.

[0010] Specifically, the lower part of the hollow cover is provided with a hollow connecting column, and a fixing column is provided on the outside of the speed reduction transmission assembly corresponding to the position of the hollow connecting column. A connecting screw passes through the hollow connecting column and connects to the fixing column, so that the lower part of the hollow cover is stably and firmly connected to the speed reduction transmission assembly.

[0011] Specifically, the reduction transmission assembly includes a housing, a transmission gear set, and an output shaft. The transmission gear set is housed within the housing, one end of the output shaft is fixed to the transmission gear set, and the other end of the output shaft extends out of the housing. The drive shaft extends into the housing, and one end of the drive shaft is equipped with a drive gear that meshes with the transmission gear set. This allows the drive shaft to drive the transmission gear set to rotate, thereby achieving a reduction in the rotation of the output shaft relative to the drive shaft. The housing provides a stable mounting platform for the transmission gear set, which is beneficial for the stable operation of the transmission gear set.

[0012] Specifically, the outer shell includes a lower shell and an upper shell. The upper shell has a mounting cavity, the transmission gear set is placed on the mounting cavity, the lower shell covers the lower opening of the upper shell, one end of the drive shaft extends into the mounting cavity, and the motor is fixed on the outside of the upper shell. The connected lower shell and upper shell have a simple structure and are easy to implement, and it is also convenient to install the transmission gear set in the outer shell.

[0013] Another objective of this utility model is achieved as follows: A food processing machine including the aforementioned drive module includes a main housing, characterized in that a first mounting space and a second mounting space are provided within the main housing, the drive module is fixed within the main housing, the motor and motor cover are located in the first mounting space, and a portion of the reduction gear transmission assembly is located in the second mounting space; in this food processing machine, the components of the drive module have a compact structure and a small overall volume, which allows the overall volume of the main housing to be made smaller, thus reducing product production costs. Furthermore, the first and second mounting spaces ensure that the installation positions of the motor and motor cover and the reduction gear transmission assembly within the main housing are independent and do not affect each other.

[0014] Furthermore, the motor cover is also provided with a positioning protrusion, and a positioning groove is opened on the first placement space corresponding to the position of the positioning protrusion, with the positioning protrusion extending into the positioning groove; through the cooperation of the positioning protrusion and the positioning groove, the motor cover together with the entire drive module is installed and positioned in the main unit housing, which facilitates the installation and fixation of the drive module in the main unit housing.

[0015] Specifically, it further includes a power cord and a locking cover. A limiting wall with a limiting recess is provided on the outer side of the speed reduction transmission assembly. One end of the power cord is electrically connected to the circuit board and the power cord is placed on the limiting recess. The locking cover is fixed to the limiting wall so that the power cord is clamped between the limiting wall and the limiting recess. This realizes the installation and positioning of the power cord in the main unit housing and avoids the power cord from moving around in the main unit housing and causing easy damage.

[0016] The beneficial effects of this utility model are as follows: This drive module, by fixing the circuit board to the motor cover and the motor cover and motor to the reduction gear assembly, allows the motor, reduction gear assembly, motor cover and circuit board to form an integrated module. This facilitates the installation and fixation of this integrated module on an external carrier. Moreover, this integrated module is applicable to different external carriers and has wide applicability. Furthermore, the compact structure between the components of this integrated module helps to reduce the overall size of the drive module and the overall size of the external carrier.

[0017] The isolation space ensures the stable operation of the circuit board, while the guide slot provides good guidance and positioning for the circuit board in the placement space, facilitating the installation operation of the circuit board.

[0018] This food processing machine features a compact structure and small overall size among the components of its drive module, which allows for a smaller overall size of the main unit housing, thus reducing production costs. Furthermore, the first and second installation spaces ensure that the motor, motor cover, and speed reduction transmission components are installed independently within the main unit housing without affecting each other.
