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 blender head. The blender head includes a lid, a blending motor assembly, and a lifting drive mechanism. The blending motor assembly and the lifting drive mechanism are assembled into the lid. The blending motor assembly includes a blending motor and a blending element. The blending motor is driven by the blending element to drive its rotation. The lifting drive mechanism is driven by the blending motor assembly to drive its lifting motion relative to the lid. Because the lifting drive mechanism can drive the blending motor assembly to move up and down, the blending element stirs the food during this process. This allows the blending element to agitate food at different heights within the container, resulting in better mixing. By incorporating the lifting drive mechanism within the lid, the blending motor assembly can be driven to move up and down without increasing the size of the blender, thus facilitating product miniaturization. Furthermore, when heating and cooking food, the blending motor assembly can be controlled to move upwards, preventing the blending element from immersing in the food slurry, thereby reducing energy consumption.

[0005] Furthermore, the lifting drive mechanism includes a lifting motor and a lead screw assembly. The lead screw assembly includes a lead screw and a lifting seat that cooperates with the lead screw. The lifting motor is driven by the lead screw, and the lifting seat is fixedly connected to the stirring motor. The lifting motor drives the lead screw to rotate, thereby causing the lifting seat to move up and down. In this way, the up and down movement of the stirring motor assembly can be achieved through a simple and reliable structure.

[0006] 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 lifting seat is connected to either the stator support or the motor housing. This achieves a fixed connection between the lifting seat and the stirring motor, enabling the lifting seat to drive the stirring motor assembly in a lifting motion.

[0007] 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.

[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 upper cover is detachably assembled to the lower cover, and the lower cover is provided with a feeding port. When using the food processor, the blender head cover can be placed on the blending cup assembly first, then the upper cover can be removed, and the ingredients can be added into the receiving cavity of the blending cup assembly through the feeding port. This avoids the situation where the blender head cover is difficult to close properly due to the food obstructing the blending components when the ingredients are placed in the blending cup assembly first and then placed on the blender head assembly. In addition, the feeding port allows ingredients to be added during the operation of the food processor, making it more convenient to use.

[0012] Furthermore, the cup lid includes a middle lid, which is assembled to the lower lid, and the lifting motor is enclosed between the middle lid and the lower lid. Thus, by enclosing the lifting motor between the middle lid and the lower lid, the lifting motor is not exposed when the upper lid is removed for feeding.

[0013] Furthermore, the stirring motor assembly includes a baffle, and the stirring motor includes a motor housing, a stator, and a rotor. The stator and the rotor are disposed within the motor housing, and the baffle is fixed to the motor housing and surrounds the stirring element. By providing a baffle surrounding the stirring element, a turbulence effect can be achieved during the stirring process of the stirring element rotating and agitating the food, thereby improving the agitation effect.

[0014] Furthermore, the shroud is provided with several flow-disrupting holes. During the stirring process, the food flows inside and outside the shroud through the flow-disrupting holes, thereby giving the shroud a better flow-disrupting effect.

[0015] 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.

[0023] 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.

[0024] 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.

[0025] The blender head 40 includes a cup lid 10, a blending motor assembly 20, and a lifting drive mechanism 30. The blending motor assembly 20 and the lifting drive mechanism 30 are assembled to the cup lid 10. The blending motor assembly 20 includes a blending motor 21 and a blending element 22. The blending motor 21 is driven to the blending element 22 to drive it to rotate. The lifting drive mechanism 30 is driven to the blending motor assembly 20 to drive it to move up and down relative to the cup lid 10. The blending element 22 is located inside the receiving cavity 51 and is used to blend and pulverize the food inside the receiving cavity 51. The blending element 22 can be a blade, but is not limited to this.

[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 in the container cavity 51, resulting in better stirring effect. By setting the lifting drive mechanism 30 inside the cup lid 10, the stirring motor assembly 20 can be driven to move up and down without increasing the volume 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 upward to prevent the stirring element 22 from being immersed in the food slurry, thereby reducing energy consumption.

[0027] In the illustrated embodiment, the lifting drive mechanism 30 includes a lifting motor 31 and a lead screw assembly 32. The lead screw assembly 32 includes a lead screw 321 and a lifting seat 322 that cooperates with the lead screw 321. The lifting motor 31 is driven to the lead screw 321, and the lifting seat 322 is fixedly connected to the stirring motor 21. The lifting motor 31 drives the lead screw 321 to rotate, thereby causing the lifting seat 322 to move up and down. When the lifting motor 31 starts, it drives the lead screw 321 to rotate, which in turn causes the lifting seat 322 to move up and down along the lead screw 321. The lifting seat 322 then drives the stirring motor assembly 20 to move up and down. Thus, the up and down movement of the stirring motor assembly 20 can be achieved through a simple and reliable structure. Of course, the lead screw assembly 32 can also be replaced with other mechanisms, which are not listed here.

[0028] 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 lifting seat 322 is connected to either the stator support 214 or the motor housing 211. This achieves a fixed connection between the lifting seat 322 and the stirring motor 21, enabling the lifting seat 322 to drive the stirring motor assembly 20 to perform lifting movements. In the illustrated embodiment, the lifting seat 322 and the stator support 214 are integrally formed. In another embodiment, the lifting seat 322 and the stator support 214 are separately formed and then fixed together. In other embodiments, the lifting seat 322 is integrally formed or fixed together with the motor housing 211.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] The upper cover 11 is detachably assembled to the lower cover 12, and the lower cover 12 is provided with a feeding port 122. When using the food processor 100, the blender head 40 can be placed on the blending cup assembly 50 first, then the upper cover 11 can be removed, and then the ingredients can be put into the receiving cavity 51 of the blending cup assembly 50 through the feeding port 122. This avoids the situation where the blender head 40 is difficult to close properly due to the obstruction of the blending elements 22 when the ingredients are put into the blending cup assembly 50 first and then the blender head 40 is placed on the blending cup assembly 50. In addition, by providing the feeding port 122, ingredients can be added during the operation of the food processor 100, making it more convenient to use.

[0034] The cup lid 10 includes a middle lid 13, which is assembled to the lower lid 12. The lifting motor 31 is enclosed between the middle lid 13 and the lower lid 12. Thus, by enclosing the lifting motor 31 between the middle lid 13 and the lower lid 12, the lifting motor 31 is not exposed when the upper lid 11 is removed for feeding. Additionally, the control circuit board (not shown) and leads can also be enclosed between the middle lid 13 and the lower lid 12. The upper coupler 37 is fixed between the middle lid 13 and the lower lid 12, and the upper coupler 37 passes through the lower lid 12. The stirring cup assembly 50 includes a lower coupler 57 that mates with the upper coupler 37. In the illustrated embodiment, the fixing bracket 38 and the lower lid 12 are fixed together by fasteners, and the fixing bracket 38 and the lower lid 12 cooperate to fix the lifting motor 31.

[0035] The stirring motor assembly 20 includes a baffle 25. The stirring motor 21 includes a motor housing 211, a stator 212, and a rotor 213. The stator 212 and the rotor 213 are disposed within the motor housing 211. The baffle 25 is fixed to the motor housing 211 and surrounds the stirring element 22. The baffle 25 rises and falls together with the stirring motor 21. By providing a baffle 25 surrounding the stirring element 22, a turbulence effect is achieved during the stirring process of the stirring element 22 rotating and agitating the ingredients, thereby improving the agitation effect.

[0036] In the illustrated embodiment, the baffle 25 is provided with several flow-disrupting holes 251. During the stirring process, the food flows inside and outside the baffle 25 through the flow-disrupting holes 251, thereby giving the baffle 25 a better flow-disrupting effect.
