Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processor technology, and more specifically to a speed reduction structure for a food processor and a food processor. Background Technology
[0002] Currently, most stand mixers on the market use gearboxes to reduce motor speed while increasing output torque to achieve the mixing function. However, traditional stand mixers typically use a belt-driven primary reduction gear for the motor, followed by a gear reduction gear. The output shaft of the secondary reduction gear then drives the rotating disc assembly connected to the mixing rods. This results in a large motor and gearbox, a complex structure, and high cost.
[0003] In one improved stand mixer, the motor uses a worm gear connected to a worm wheel in the gearbox to achieve primary reduction and a 90-degree reversal. Then, after a secondary reduction via the worm wheel and gears, it drives the rotating disc assembly connected to the mixing rod. Although this method has a large reduction ratio and reduces the space occupied, the motor worm and worm wheel are separate, resulting in poor concentricity and low torque. In another improved stand mixer, the motor uses planetary gears for primary reduction, and then uses bevel gears to reverse the direction by 90 degrees before driving the rotating disc assembly connected to the mixing rod. The planetary gear reduction ratio is small, and multiple stages of planetary gear reduction are required to reduce the speed from high to low, resulting in very high manufacturing costs.
[0004] To address the above issues, Chinese patent CN219611533U discloses a reduction structure for a food processor. The motor worm gear is placed horizontally, with two worm wheels installed on the left and right sides of the worm gear to ensure concentricity when the worm gear rotates under force. The primary output shaft, secondary input shaft, secondary output shaft, and tertiary input shaft are coaxially connected, making the entire reduction structure compact and space-saving. However, this prior art uses expensive planetary gears in its secondary transmission, resulting in a still high cost. Furthermore, the motor is not centrally mounted to the main unit, preventing the addition of front and rear output functions and limiting product functionality. Utility Model Content
[0005] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a speed reduction structure for a food processor and a food processor in general, which has a simple structure, lower cost, and more functions.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a reduction structure for a food processor, including a motor, a two-stage gear, a gearbox cover and a rotating disk assembly;
[0007] The motor is equipped with a motor worm and two worm wheels, which are symmetrically arranged on both sides of the motor worm. At least one worm wheel is equipped with a coaxial primary gear. The primary gear meshes with the secondary gear, and the secondary gear is mounted on the gearbox cover. The rotating disk assembly is mounted on the lower part of the gearbox cover.
[0008] The intermediate shaft of the secondary gear passes through the gearbox cover and is inserted into the input hole of the rotating disk assembly so that the secondary gear rotates coaxially with the rotating disk assembly. The output shaft of the rotating disk assembly is connected to a stirring rod.
[0009] This technical solution provides a speed reduction structure for a food processor. It uses a motor worm gear to drive two worm wheels to complete the first-stage speed reduction and 90-degree direction change. Then, the worm wheels drive the second-stage gear for speed reduction. At the same time, the second-stage gear directly drives the rotating disc assembly connected to the mixing rod. The structure is simple, compact, and has low processing cost.
[0010] In a preferred embodiment, the front end of the gearbox cover is provided with a front output assembly, which includes a first front bevel gear and a second front bevel gear that are vertically meshed. The second front bevel gear meshes with a secondary gear.

[0011] In a preferred embodiment, the rear end of the motor is provided with a rear output component, which includes a first rear bevel gear and a second rear bevel gear that are vertically meshed. The first rear bevel gear is mounted on the motor shaft at the rear end of the motor. The rear output component can achieve steering output through the meshing between the first rear bevel gear and the second rear bevel gear, thereby increasing the rear output function.
[0012] In a preferred embodiment, the motor worm is arranged laterally, with two worm wheels symmetrically positioned on the left and right sides of the motor worm to ensure concentricity and good stability when the motor worm is subjected to rotational force.
[0013] In a preferred technical solution, the motor, motor worm, and two worm gears are integrated into a single structure, which has high concentricity, good stability, small size, large speed ratio, and can achieve 90-degree direction change.
[0014] In a preferred embodiment, an internal gear ring is provided inside the gearbox cover, and the rotating disk assembly is installed inside the internal gear ring. A cavity for installing the secondary gear is formed between the gearbox cover and the bottom shell of the rotating disk assembly, facilitating the installation of the secondary gear.
[0015] In a preferred embodiment, the rotating disk assembly includes at least one planetary gear located within and meshing with an internal gear ring. The planetary gear also has an output shaft for connecting to a stirring rod. In this technology, the rotating disk assembly drives the stirring rods via the planetary gears, enabling multiple stirring rods to operate simultaneously.
[0016] In a preferred embodiment, the motor is mounted above the gearbox cover, and the top surface of the gearbox cover has a mounting hole for the secondary gear to pass through, which facilitates the installation of the secondary gear.
[0017] A food processor includes a speed reduction structure as described in any of the above-mentioned technical solutions.
[0018] The food processor in this technology adopts the speed reduction structure of the aforementioned food processor, which is simple in structure, compact in size, and has low processing cost.
[0019] In a preferred embodiment, the motor is located in the middle of the food processor, allowing the product to have both front and rear output functions, thus enhancing its functionality.
[0020] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are as follows: The reduction structure of the food processor provided by this utility model uses a motor worm gear to drive two worm wheels to complete the first-stage reduction and 90-degree change of direction. Then, the worm wheels drive the second-stage gear for reduction. At the same time, the second-stage gear directly drives the rotating disk assembly connected to the stirring rod. The structure is simple, compact, and has low processing cost. Furthermore, the motor worm gear and the two worm wheels are integrated into one structure, with high concentricity, good stability, small size, large speed ratio, and the ability to achieve 90-degree change of direction. Furthermore, the motor can be located in the center of the food processor, allowing the product to have front and rear output functions, thus increasing the product's functionality.

The speed reduction structure can be used in kitchen appliances such as food processors, mixers, dough mixers, egg beaters, and high-powered mixers.
[0030] In one embodiment, such as Figure 1-2 As shown, a speed reduction structure for a food processor includes a motor 1, a secondary gear 2, a gearbox cover 3, and a rotating disk assembly 4. The motor 1 has a motor worm 12 and two worm wheels 11, which are symmetrically arranged on both sides of the motor worm 12. At least one worm wheel 11 has a coaxial primary gear 111. The primary gear 111 meshes with the secondary gear 2, which is mounted on the gearbox cover 3. The rotating disk assembly 4 is mounted on the lower part of the gearbox cover 3.

The output shaft 42 of the rotating disk assembly 4 is connected to a stirring rod 5.
[0031] The motor worm gear 12 is placed horizontally, and two worm wheels 11 are respectively installed on the left and right sides of the motor worm gear 12 to ensure the concentricity of the motor worm gear 12 when it is subjected to rotational force.
[0032] In specific implementation, the lowest end of the worm gear 11 is provided with a first-stage gear 111, which is connected and meshed with the second-stage gear 2. The second-stage gear 2 is installed on the gearbox cover 3. The intermediate shaft of the second-stage gear 2 is inserted into the input hole 41 of the rotating disk assembly 4 to drive the rotating disk assembly 4 to rotate, which in turn drives the stirring rod 5 installed on the output shaft 42 of the rotating disk assembly 4 to rotate, thereby realizing the stirring function. The entire reduction structure is compact and occupies little space.
[0033] The above embodiment provides a speed reduction structure for a food processor, which uses a motor worm gear 12 to drive two worm wheels 11 to complete the first-stage speed reduction and 90-degree change of direction. Then, the worm wheels 11 drive the second-stage gear 2 for speed reduction. At the same time, the second-stage gear 2 directly drives the rotating disk assembly 4 connected to the stirring rod 5. The structure is simple, compact, and has low processing cost.
[0034] In this embodiment, the front end of the gearbox cover 3 is provided with a front output component 6. The front output component 6 includes a first front bevel gear 61 and a second front bevel gear 62 that are vertically meshed. The second front bevel gear 62 meshes with the secondary gear 2.

[0036] like Figure 3 As shown, the above-mentioned deceleration structure, by adding a front output component 6 and a rear output component 7, can realize the output steering of the front and rear ends, making its functions more diversified.
[0037] In this embodiment, the motor worm gear 12 is arranged horizontally, and two worm wheels 11 are symmetrically arranged on the left and right sides of the motor worm gear 12 to ensure the concentricity of the motor worm gear 12 when it is subjected to rotational force, thus ensuring good stability.

In specific implementation, the rotating disk group 4 can have one or more output shafts 42, and the number of stirring rods 5 can be designed according to actual needs.
[0042] In this embodiment, the motor 1 is mounted above the gearbox cover 3. The top surface of the gearbox cover 3 is provided with a mounting hole 32 for the secondary gear 2 to pass through, which facilitates the installation of the secondary gear.
[0043] The mounting hole 32 can be a hole that matches the shape of the shaft of the secondary gear 2, so as to facilitate the installation of the secondary gear 2.
