Description

Technical Field

[0001] This application relates to the field of food processing, and more particularly to a mixing blade assembly, a mixing cup assembly, and a food processor. Background Technology

[0002] As people's living standards continue to improve, many different types of food processors have appeared on the market. The functions of food processors mainly include, but are not limited to, making soy milk, juicing, rice paste, mincing meat, shaved ice, making coffee, and / or preparing face masks. However, when making thick ingredients (such as jam) in existing food processors, large particles tend to stick to the bottom and sides of the blending cup. This requires stopping the machine and using the stirring rod to tumble the ingredients evenly, which is cumbersome and results in a poor user experience. Utility Model Content

[0003] This application provides a mixing blade assembly, a mixing cup assembly, and a food processor, which can prevent food from sticking to the bottom and side walls of the mixing cup, and can evenly crush food without the need for manual stirring, resulting in a better user experience.

[0004] This application provides a mixing blade assembly. The mixing blade assembly includes: a blade disc, a rotating shaft, a reduction gear device, a mixing blade, and a mixing element. The rotating shaft passes through the blade disc. The reduction gear device includes a sun gear, a planetary gear set, and a ring gear. The sun gear is fixed to the rotating shaft. The planetary gear set includes an output shaft passing through the blade disc. The mixing blade is fixed to the top of the rotating shaft. The mixing element is fixed to the output shaft and is located between the blade disc and the mixing blade. Because the mixing element is fixed to the output shaft, the rotational speed of the rotating shaft is reduced by the reduction gear device and then transmitted to the mixing element. When the mixing element rotates at low speed, it can scrape off the food adhering to the blade disc and / or the inner wall of the mixing cup. Thus, while the mixing blade is pulverizing the food, the mixing element automatically tumbles the food, preventing the food from adhering to the blade disc and / or the inner wall of the mixing cup, resulting in more uniform pulverization. No manual tumbling of the food is required, providing a better user experience.

[0005] Furthermore, the reduction gear device can be a single-stage gear reduction device, a two-stage gear reduction device, or a multi-stage reduction device. This allows for the achievement of a suitable reduction ratio according to specific needs.

[0006] Furthermore, the stirring blade assembly also includes a bottom cover fixed to the blade disc, forming a closed cavity between the blade disc and the bottom cover, and the reduction gear device is disposed within the cavity. Thus, placing the reduction gear device within the closed cavity provides protection for the reduction gear device.

[0007] In another aspect, this application provides a mixing cup assembly, which includes: a mixing cup; and a mixing blade assembly as described above, disposed at the bottom of the mixing cup.

[0008] Furthermore, the stirring element includes a first part for scraping the blade disc and a second part for scraping the inner wall of the mixing cup. Thus, the stirring element can simultaneously scrape both the blade disc and the inner wall of the mixing cup.

[0009] Furthermore, the distance between the first part and the blade disc ranges from 0 mm to 5 mm. This allows the first part to effectively scrape off food adhering to the blade disc.

[0010] Furthermore, the distance between the second part and the inner wall of the mixing cup ranges from 0 mm to 5 mm. The second part can effectively scrape off the food adhering to the inner wall of the mixing cup.

[0011] Furthermore, the second part includes a frame and a scraper disposed on the frame, wherein the frame is made of a rigid material and the scraper is made of a soft material. Because the scraper is made of a soft material, it can contact the inner wall of the mixing cup, thus avoiding noise and preventing damage to the mixing cup.

[0012] Furthermore, the blade assembly is detachably mounted on the bottom of the mixing cup; or, the blade assembly is fixed to the bottom of the mixing cup. This allows the blade assembly to be disassembled for cleaning after use, making cleaning more convenient and thorough.

[0013] This application also provides a food processor, which includes: a main unit, including a housing and a motor disposed within the housing; and a mixing cup assembly as described above, assembled to the main unit. Attached Figure Description

[0017] Please see Figures 1 to 5 The food processor 100 includes a main unit 80, a blending cup assembly 90, and a lid assembly 99. The blending cup assembly 90 is assembled to the main unit 80, which includes a housing 81 and a motor 82 disposed within the housing 81. The lid assembly 99 covers the blending cup assembly 90.

[0018] The mixing cup assembly 90 includes a mixing cup 60 and a mixing blade assembly 70, wherein the mixing blade assembly 70 is disposed at the bottom of the mixing cup 60.

[0019] The stirring blade assembly 70 includes: a blade disc 10, a rotating shaft 20, a reduction gear device 30, a stirring blade 40, and a stirring element 50. The rotating shaft 20 passes through the blade disc 10. The reduction gear device 30 includes a sun gear 31, a planetary gear set 32, and a ring gear 33. The sun gear 31 is fixed to the rotating shaft 20. The planetary gear set 32 ​​includes an output shaft 320 passing through the blade disc 10. The stirring blade 40 is fixed to the top of the rotating shaft 20. The stirring element 50 is fixed to the output shaft 320 and is located between the blade disc 10 and the stirring blade 40. The rotating shaft 20 is connected to the motor shaft 821 of the motor 82 via upper and lower clutches (not shown). A sealing ring 66 forms a seal between the blade disc 10 and the stirring cup 60.

[0020] Since the mixing element 50 is fixed to the output shaft 320, the rotation speed of the rotating shaft 20 is reduced by the reduction gear device 30 and then transmitted to the mixing element 50. When the mixing element 50 rotates at low speed, it can scrape off the food that is adhering to the inner wall of the blade 10 and / or the mixing cup 60. In this way, while the mixing blade 40 is crushing the food, the mixing element 50 automatically stirs the food, preventing the food from adhering to the inner wall of the blade 10 and / or the mixing cup 60, making the crushing more uniform. There is no need for manual stirring of the food, resulting in a better user experience.

[0021] The reduction gear device 30 can be a single-stage gear reduction device, a two-stage gear reduction device, or a multi-stage reduction device. In this way, a suitable reduction ratio can be achieved according to specific needs.

[0022] In the illustrated embodiment, the reduction gear device 30 is a three-stage gear reduction device. The planetary gear set 32 ​​includes a first-stage planetary gear assembly 321, a second-stage planetary gear assembly 322, and a third-stage planetary gear assembly 323. The first-stage planetary gear assembly 321 includes a first gear carrier 3211 and a first planetary gear 3212 mounted on the first gear carrier 3211. The first planetary gear 3212 meshes with a sun gear 31 and a ring gear 33. A second-stage sun gear 3214 is provided at the top of the first gear carrier 3211. The second-stage planetary gear assembly 322 includes a second gear support 3221 and a second planetary gear 3222 mounted on the second gear support 3221. The second planetary gear 3222 meshes with the second-stage sun gear 3214 and the ring gear 33. A third-stage sun gear 3224 is provided at the top of the second gear support 3221. The third-stage planetary gear assembly 323 includes a third gear support 3231 and a third planetary gear 3232 mounted on the third gear support 3231. The third planetary gear 3232 meshes with the third-stage sun gear 3224 and the ring gear 33. The output shaft 320 is fixed to the third gear support 3231. Thus, the reduction gear device 30 achieves three-stage reduction.

[0023] In the illustrated embodiment, the stirring blade assembly 70 further includes a bottom cover 19 fixed to the blade disc 10, forming a closed cavity 18 between the blade disc 10 and the bottom cover 19, and the reduction gear device 30 is disposed within the cavity 18. Thus, placing the reduction gear device 30 within the closed cavity 18 provides protection for the reduction gear device 30.

[0024] The stirring element 50 includes a first part 51 for scraping the blade 10 and a second part 52 for scraping the inner wall of the mixing cup 60. Thus, the stirring element 50 can simultaneously scrape both the blade 10 and the inner wall of the mixing cup 60.

[0025] In some embodiments, the stirring element 50 may be made of a rigid material, such as plastic or metal. In other embodiments, the stirring element 50 may be made of a soft material, such as rubber or silicone. In still other embodiments, the stirring element 50 includes a skeleton made of a rigid material and a soft material covering the skeleton.

[0026] Preferably, the distance between the first portion 51 and the blade disc 10 is between 0 mm and 5 mm. This allows the first portion 51 to effectively scrape off food adhering to the blade disc 10. In some embodiments, the distance between the first portion 51 and the blade disc 10 can be 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, or any value between any two adjacent values ​​mentioned above.

[0027] The distance between the second part 52 and the inner wall of the mixing cup 60 is between 0 mm and 5 mm. In this way, the second part 52 can effectively scrape off the food adhering to the inner wall of the mixing cup 60.

[0028] The second part 52 includes a frame 521 and a scraper part 522 disposed on the frame 521. The frame 521 is made of a hard material, and the scraper part 522 is made of a soft material. Because the scraper part 522 is made of a soft material, it can contact the inner wall of the mixing cup 60, thus avoiding noise and preventing damage to the mixing cup 60.

[0029] In the illustrated embodiment, the blade assembly 70 is detachably mounted on the bottom of the mixing cup 60. This allows the blade assembly 70 to be disassembled for cleaning after use of the food processor 100, making cleaning more convenient and thorough.

[0030] In another embodiment, the stirring blade assembly 70 is fixed to the bottom of the stirring cup. This makes the stirring cup assembly structure more stable.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
