Description

Technical Field

[0001] This application relates to the field of food processing, and more particularly to a blender head and a food processor. Background Technology

[0002] With the continuous improvement of people's living standards, 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. Food processors can include soy milk makers, blenders, or high-speed blenders—machines that pulverize and mix food. Currently, food processors have the problem of poor blending performance. Utility Model Content

[0003] This application provides a mixer head and a food processor that effectively blends ingredients.

[0004] This application provides a mixer head. The mixer head includes a cup lid; a mixing motor assembly assembled on the cup lid, the mixing motor assembly including a mixing motor and a mixing element, the mixing motor being drivenly connected to the mixing element to drive the mixing element to rotate; and a lifting drive mechanism assembled on the cup lid, the lifting drive mechanism including a lifting motor and a gear and rack assembly, the gear and rack assembly including a gear and a rack meshing with the gear, the lifting motor being drivenly connected to the gear, the rack being fixedly connected to the mixing motor, the lifting motor driving the gear to rotate, causing the rack to drive the mixing motor assembly to move up and down relative to the cup lid. Because the lifting drive mechanism can drive the stirring motor assembly to move up and down, the stirring components stir the ingredients during the up-and-down movement of the stirring motor assembly. This allows the stirring components to agitate ingredients at different heights within the container, resulting in better stirring. By incorporating a lifting drive mechanism within the lid, which includes a lifting motor and a gear and rack assembly (comprising gears and a rack), the lifting motor drives the gears to rotate, causing the rack to move the stirring motor assembly up and down. This structure is stable and reliable, and does not increase the size of the food processor, thus facilitating product miniaturization. Furthermore, when heating and cooking ingredients, the stirring motor assembly can be controlled to move upwards, preventing the stirring components from being submerged in the food slurry, thereby reducing energy consumption.

[0005] Furthermore, the stirring motor includes a motor housing, a stator, a rotor, and a stator support. The stator and the rotor are disposed within the motor housing, and the stator support is fixed to both the stator and the motor housing. The rack is connected to either the stator support or the motor housing. This achieves a fixed connection between the rack and the stirring motor, enabling the rack to drive the stirring motor assembly in a lifting motion.

[0006] Furthermore, the rotor is located outside the stator, and a bearing is provided between the rotor and the stator. In this way, the stirring motor is small in size, making the stirring motor assembly structure more compact.

[0007] Furthermore, the rack and the stator support are integrally formed. This simplifies manufacturing and makes the structure more reliable.

[0008] Furthermore, the stirring motor includes a rotating shaft fixed to the rotor, the rotating shaft extending out of the motor housing, the stirring element fixed to the rotating shaft, and a bearing and a shaft seal ring provided between the rotating shaft and the motor housing. The shaft seal ring achieves a seal for the stirring motor, preventing liquid from entering the stirring motor from between the rotating shaft and the motor housing.

[0009] Furthermore, the cup lid includes a lower lid and an upper lid. The lower lid has a guide cylinder extending away from the upper lid, and the stirring motor is disposed within the guide cylinder, which is movable up and down. By providing the guide cylinder, the stirring motor moves up and down along the guide cylinder, thus the guide cylinder can guide the up and down movement of the stirring motor and prevent the stirring motor from swaying during the up and down movement.

[0010] Furthermore, a motor sealing ring is provided at the bottom end of the guide cylinder, and the motor sealing ring presses radially inward against the stirring motor. By pressing the motor sealing ring against the stirring motor, liquid or food is prevented from entering the guide cylinder from the gap between the guide cylinder and the stirring motor; in addition, during the up-and-down movement of the stirring motor, the motor sealing ring can scrape off the food adhering to the stirring motor.

[0011] Furthermore, the bottom end of the guide cylinder is provided with a mounting groove, and the motor sealing ring includes a mounting part fixed in the mounting groove and a pressing part pressing against the stirring motor. Thus, by cooperating with the mounting groove, the motor sealing ring can be assembled onto the guide cylinder, making assembly convenient.

[0012] Furthermore, the cup lid includes a lower lid, an upper lid, and a fixing bracket, the fixing bracket and the lower lid cooperating to fix the lifting motor. This allows the lifting motor to be conveniently and reliably fixed inside the cup lid.

[0013] Furthermore, the fixing frame includes a sleeve through which the stirring motor passes. The sleeve guides the lifting and lowering of the stirring motor, preventing it from swaying during the lifting and lowering process.

[0014] This application also provides a food processor. The food processor includes: a blending cup assembly including a receiving cavity; and a blender head as described above, which is disposed on the blending cup assembly, and the blending element is located within the receiving cavity.

[0022] Please see Figures 1 to 5 The food processor 100 can be a blender, juicer, high-speed blender, stir-fry machine, soy milk maker, meat grinder, etc.

[0023] The food processor 100 includes a blending cup assembly 50 and a blender head 40, with the blender head 40 covering the blending cup assembly 50. The blending cup assembly 50 includes a receiving cavity 51 for holding food ingredients. In the illustrated embodiment, the blending cup assembly 50 includes a blending cup 59 and a heating plate 58 disposed at the bottom of the blending cup 59 for heating the food ingredients.

[0024] The blender head 40 includes a cup lid 10, a blending motor assembly 20, and a lifting drive mechanism 30, which are assembled to the cup lid 10. The blending motor assembly 20 includes a blending motor 21 and a blending element 22, with the blending motor 21 drivingly connected to the blending element 22 to drive its rotation. The blending element 22 is located within a receiving cavity 51 and is used to blend and pulverize the food within the receiving cavity 51. The blending element 22 can be a blade, but is not limited to this. The blender head 40 also includes an upper coupler 19 assembled to the cup lid 10, and the blending cup assembly 50 includes a lower coupler 56 assembled to the blending cup 59. The upper coupler 19 and the lower coupler 56 are connected to form an electrical connection.

[0025] The lifting drive mechanism 30 includes a lifting motor 31 and a gear and rack assembly 32. The gear and rack assembly 32 includes a gear 321 and a rack 322 meshing with the gear 321. The lifting motor 31 is driven to the gear 321, and the rack 322 is fixedly connected to the stirring motor 21. The lifting motor 31 drives the gear 321 to rotate, causing the rack 322 to drive the stirring motor assembly 20 to move up and down relative to the cup lid 10.

[0026] Since the lifting drive mechanism 30 can drive the stirring motor assembly 20 to move up and down, the stirring element 22 stirs the food during the up-and-down movement of the stirring motor assembly 20. This allows the stirring element 22 to stir the food at different heights within the container cavity 51, resulting in better stirring effect. By setting the lifting drive mechanism 30 inside the lid 10, which includes a lifting motor 31 and a gear and rack assembly 32 (including a gear 321 and a rack 322), the lifting motor 31 drives the gear 321 to rotate, which in turn causes the rack 322 to drive the stirring motor assembly 20 to move up and down. The structure is stable and reliable, and it does not increase the size of the food processor 100, which is conducive to product miniaturization. In addition, when heating and cooking the food, the stirring motor assembly 20 can be controlled to move upwards, preventing the stirring element 22 from being immersed in the food slurry, thereby reducing energy consumption.

[0027] The stirring motor 21 includes a motor housing 211, a stator 212, a rotor 213, and a stator support 214. The stator 212 and the rotor 213 are disposed within the motor housing 211. The stator support 214 is fixed to both the stator 212 and the motor housing 211. The rack 322 is connected to either the stator support 214 or the motor housing 211. This secure connection between the rack 322 and the stirring motor 21 enables the rack 322 to drive the stirring motor assembly 20 in a lifting motion.

[0028] In the illustrated embodiment, the rack 322 and the stator support 214 are integrally formed. This simplifies manufacturing and makes the structure more reliable.

[0029] In another embodiment, the rack 322 and the stator support 214 are respectively formed and then fixed together. In other embodiments, the rack 322 is integrally formed or fixed together with the motor housing 211.

[0030] In the illustrated embodiment, the stirring motor 21 is an external rotor motor, with the rotor 213 disposed outside the stator 212. A bearing 216 is provided between the rotor 213 and the stator 212. This results in a small stirring motor 21, making the stirring motor assembly 20 more compact. In another embodiment, the stirring motor 21 is an internal rotor motor.

[0031] In the illustrated embodiment, the stirring motor 21 includes a rotating shaft 215 fixed to the rotor 213, the rotating shaft 215 extending out of the motor housing 211, the stirring element 22 fixed to the rotating shaft 215, and a bearing 216 and a shaft seal ring 217 provided between the rotating shaft 215 and the motor housing 211. The shaft seal ring 217 is used to seal the stirring motor 21, preventing liquid from entering the stirring motor 21 from between the rotating shaft 215 and the motor housing 211.

[0032] The cup lid 10 includes a lower lid 12 and an upper lid 11. The lower lid 12 is provided with a guide cylinder 121 extending away from the upper lid 11. The stirring motor 21 is disposed within the guide cylinder 121, allowing it to move up and down. By providing the guide cylinder 121, the stirring motor 21 moves up and down along the guide cylinder 121. In this way, the guide cylinder 121 can guide the up and down movement of the stirring motor 21, preventing the stirring motor 21 from swaying during the up and down movement.

[0033] The bottom end of the guide cylinder 121 is provided with a motor sealing ring 123, which presses radially inward against the stirring motor 21. By pressing the motor sealing ring 123 against the stirring motor 21, liquid or food is prevented from entering the guide cylinder 121 from the gap between the guide cylinder 121 and the stirring motor 21; in addition, during the up-and-down movement of the stirring motor 21, the motor sealing ring 123 can scrape off the food stuck to the stirring motor 21.

[0034] In the illustrated embodiment, the bottom end of the guide cylinder 121 is provided with a mounting groove 1211, and the motor sealing ring 123 includes a mounting part 1231 fixed in the mounting groove 1211 and a pressing part 1232 pressing against the stirring motor 21. Thus, by cooperating with the mounting part 1231 and the mounting groove 1211, the motor sealing ring 123 is assembled onto the guide cylinder 121, making assembly convenient.

[0035] The cup lid 10 includes a lower lid 12, an upper lid 11, and a fixing bracket 13. The fixing bracket 13 and the lower lid 12 cooperate to fix the lifting motor 31. In this way, the lifting motor 31 can be conveniently and reliably fixed inside the cup lid 10. Specifically, the fixing bracket 13 is fixed to the lower lid 12 by fasteners, and the lifting motor 31 is clamped and fixed by the fixing bracket 13 and the lower lid 12.

[0036] The fixing frame 13 includes a sleeve 131 through which the stirring motor 21 passes. The sleeve 131 guides the lifting and lowering of the stirring motor 21, preventing the stirring motor 21 from swinging during the lifting and lowering process.

[0037] 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.
