[0081] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0082] Please refer to Figure 1-4 This application provides a food processor 1, which includes a cup body assembly 2, a main unit 3, and a cup lid assembly 4.

[0083] The cup assembly 2 includes a cup body 20, a heating module 21, and a stirring module 22. A lid assembly 4 covers the cup body 20 and cooperates with it to form a receiving cavity 2A. The cup body 20 is used to hold food, and the heating module 21 is used to heat the food in the receiving cavity 2A. The heating method of the heating module 21 can be at least one of resistance heating, infrared heating, and electromagnetic heating. In other embodiments, the heating module 21 can also employ other heating methods. In this embodiment, the specific heating method of the heating module 21 is not limited. It is understood that the installation position of the heating module 21 can be at least one of the bottom of the cup body 20 and the periphery of the cup body 20. In this embodiment, the installation position of the heating module 21 is not limited.

[0084] The mixing module 22 is used to mix or pulverize the ingredients in the receiving cavity 2A to suit the user's eating needs. It is understood that the mixing module 22 is detachably mounted at the bottom of the receiving cavity 2A, allowing the user to choose whether to place the mixing module 22 in the food processor 1 according to the actual food being prepared. Furthermore, the food processor 1 can be configured with multiple mixing modules 22, thereby allowing the user to conveniently select different mixing modules 22 according to different ingredients to prepare different foods. It is understood that the mixing module 22 includes at least one mixing blade; exemplaryly, the mixing module 22 may include two, three, or four mixing blades for mixing or pulverizing the ingredients in the receiving cavity 2A.

[0085] The main unit 3 is connected to and electrically connected to the cup assembly 2. The main unit 3 can be connected to a power source to supply power to the cup assembly 2. The main unit 3 includes a motor (not shown in the figure) and a controller (not shown in the figure). The motor is connected to the controller, and the output shaft of the motor can be connected to the mixing module 22 to drive the mixing module 22 to rotate, thereby stirring or crushing the food in the receiving cavity 2A. The controller can be connected to the heating module 21 to control the start and stop of the heating module 21 and the heating power to adapt to the food preparation program.

[0086] Understandably, the main unit 3 can be detachably connected to the bottom of the cup assembly 2. Compared to a non-detachable design, this allows the cup assembly 2 to be removed from the main unit 3 for cleaning, preventing water from entering the main unit 3 and reducing the probability of damage. This extends the lifespan of the main unit 3, and consequently, the lifespan of the food processor 1. Furthermore, detaching the cup assembly 2 for cleaning separately, compared to cleaning the main unit 3 and cup assembly 2 together, reduces the weight for the user, improving the convenience of cleaning the cup assembly 2.

[0087] Understandably, since the main unit 3 can be detachably connected to the cup body component 2, if either the main unit 3 or the cup body component 2 is damaged, either the main unit 3 or the cup body component 2 can be replaced or repaired separately, thereby improving the convenience of maintenance and reducing the user's maintenance costs.

[0088] The lid assembly 4 can be placed over the opening 2B of the cup body 20 to seal the opening 2B and prevent food from splashing out of the receiving cavity 2A through the opening 2B. This can prevent food waste and reduce the probability of food contaminating the outer surface of the food processor 1 or the countertop where the food processor 1 is placed, thereby improving the user's cleaning convenience and user experience.

[0089] Please refer to Figure 4 and Figure 5 In one specific embodiment, the cup lid assembly 4 includes a cup lid 41 and a fan device 42. The cup lid 41 is provided with an air inlet 411A; the fan device 42 is detachably connected to the cup lid 41 and has an air outlet 4211D (see reference). Figure 9 The blower 4211D is connected to the air inlet 411A. The blower 42 can sequentially blow airflow into the receiving cavity 2A through the blower 4211D and the air inlet 411A to break the bubbles generated when the food in the receiving cavity 2A boils and rolls, thereby preventing bubbles or food from overflowing from the opening 2B. It should be noted that the blower 42 and the cup lid 41 are detachably connected. Here, "detachable" specifically means that the blower 42 can be removed from the cup lid 41, and neither the blower 42 nor the cup lid 41 will suffer structural damage or need to break their original structural form during the removal and separation process. Specifically, the detachable connection between the blower 42 and the cup lid 41 includes at least one of screw connection, snap connection, magnetic connection, and flexible abutment. In this embodiment, there is no specific limitation on the detachable connection method between the blower 42 and the cup lid 41.

[0090] In this embodiment, since the fan device 42 is detachably connected to the cup lid 41, when the cup lid 41 needs to be cleaned, the fan device 42 can be removed from the cup lid 41 to clean the cup lid 41 separately. In this way, liquid can be prevented from entering the fan device 42 during the cleaning process, thereby reducing the probability of damage to the fan device 42 and enabling the fan device 42 to have a longer service life, so that the food processor 1 can have a longer service life.

[0091] Furthermore, since the pneumatic device 42 and the cup lid 41 are detachably connected, if the pneumatic device 42 or the cup lid 41 is damaged, the pneumatic device 42 or the cup lid 41 can be replaced or repaired separately without replacing the entire cup lid assembly 4, which can reduce the user's maintenance costs.

[0092] It is understood that the fan device 42 can be installed on the side of the cup lid 41 away from the cup body assembly 2; the fan device 42 can also be installed on the side of the cup lid 41. In this embodiment, there is no limitation on the installation position of the fan device 42 on the cup lid 41.

[0093] Please refer to Figure 7 In one embodiment, the pneumatic device 42 is at least partially exposed outside the cup lid 41 so that force can be applied to the pneumatic device 42 to separate the pneumatic device 42 from the cup lid 41, thereby improving the ease of disassembly and assembly of the pneumatic device 42.

[0094] It is understood that the pneumatic device 42 may be partially exposed on the upper surface of the cup lid 41; the pneumatic device 42 may also be at least partially exposed on the side of the cup lid 41. In the embodiments of this application, there is no limitation on the exposed position of the pneumatic device 42 on the cup lid 41.

[0095] Understandably, the pneumatic device 42 can also be flush with the outer surface of the cup lid 41. A groove (not shown in the figure) is formed between the outer wall of the housing 421 and the cup lid 41. Users can use the groove to increase the contact area with the housing, thereby making it easier to remove the pneumatic device 42 from the cup lid 41 and improving the ease of disassembly and assembly of the pneumatic device 42.

[0096] Please refer to Figure 4-7 The outer surface of the cup lid 41 is recessed to form a mounting groove 411B. The fan device 42 is at least partially embedded in the mounting groove 411B. The mounting groove 411B can increase the contact area between the fan device 42 and the cup lid 41, thereby improving the connection stability between the fan device 42 and the cup lid 41. This allows the fan device 42 to blow air into the receiving cavity 2A, thereby preventing air bubbles or food from overflowing from the opening 2B. Furthermore, the mounting groove 411B provides a positioning effect for the installation of the fan device 42, making the installation process more convenient.

[0097] Please refer to Figure 1 , Figure 4 , Figure 5-8 In one detachable connection embodiment, a snap-fit ​​structure 43 is provided between the fan device 42 and the cup lid 41, which facilitates the detachable connection between the fan device 42 and the cup lid 41 and ensures a stable connection between them, allowing the fan device 42 to stably blow air into the receiving cavity 2A. Furthermore, when the cup lid 41 needs cleaning, the snap-fit ​​structure 43 can be disconnected to detach the fan device 42 from the cup lid 41, allowing for separate cleaning of the cup lid 41. This prevents liquid from entering the fan device 42, thereby reducing the probability of damage to the fan device 42 and extending the service life of the food processor 1.

[0098] It is understood that the snap-fit ​​structure 43 can be disposed on the side of the cup lid 41 opposite to the cup body assembly 2, so as to install the fan device 42 on the side of the cup lid 41 opposite to the cup body assembly 2; the snap-fit ​​structure 43 can also be disposed on the side of the cup lid 41, so as to install the fan device 42 on the side of the cup lid 41. In the embodiments of this application, there are no restrictions on the specific location and specific form of the snap-fit ​​structure 43.

[0099] Please refer to Figure 5-9 In another specific embodiment, the snap-fit ​​structure 43 can be disposed between the side wall of the mounting groove 411B and the fan device 42, so that when the cup lid 41 and the fan device 42 have a large contact area, the snap-fit ​​structure 43 can further improve the connection stability between the cup lid 41 and the fan device 42, thereby reducing the probability of the fan device 42 detaching from the cup lid 41, and thus ensuring that the fan device 42 can blow airflow into the receiving cavity 2A to prevent bubbles or food from overflowing from the opening 2B.

[0100] Please refer to Figure 5-10 Specifically, the pneumatic device 42 includes a housing 421 and a fan 422. The housing 421 is detachably connected to the cup lid 41 and has an air outlet 4211D. The fan 422 is mounted on the housing 421 and provides airflow to the air inlet 411A via the air outlet 4211D. A snap-fit ​​structure 43 can be disposed between the housing 421 and the side wall of the mounting groove 411B.

[0101] Please refer to Figure 9In one specific embodiment, the snap-fit ​​structure 43 includes a first snap-fit ​​member 431, which is movably connected to the housing 421 and has a first snap-fit ​​portion 4312; a second snap-fit ​​portion 432 is provided on the side wall of the mounting groove 411B, and the second snap-fit ​​portion 432 snaps into the first snap-fit ​​portion 4312. It is understood that the first snap-fit ​​portion 4312 can be an insert, and the second snap-fit ​​portion 432 can be a slot; of course, the first snap-fit ​​portion 4312 can also be a slot, and the second snap-fit ​​portion 432 can also be an insert. In other embodiments, the first snap-fit ​​portion 4312 and the second snap-fit ​​portion 432 can also be in other forms. In the embodiments of this application, the specific forms of the first snap-fit ​​portion 4312 and the second snap-fit ​​portion 432 are not limited. In the embodiments of this application, the first snap-fit ​​portion 4312 as an insert and the second snap-fit ​​portion 432 as a slot will be used as an example for explanation and description.

[0102] Please refer to Figure 1 , Figure 7-9 Furthermore, the housing 421 has a through groove 4211A and a sliding groove 4211B. The first snap-fit ​​member 431 includes an actuating part 4311 and a first snap-fit ​​part 4312 connected to the actuating part 4311. The actuating part is slidably disposed in the through groove 4211A, and the first snap-fit ​​part 4312 is slidably disposed in the sliding groove 4211B.

[0103] When the pneumatic device 42 needs to be installed, the drive actuator 4311 moves along the through groove 4211A into the housing 421, thereby driving the first locking part 4312 to move along the slide groove 4211B into the housing 421. The housing 421 is moved until it is embedded in the mounting groove 411B. The drive actuator 4311 moves along the through groove 4211A outward from the housing 421, thereby driving the first locking part 4312 to move along the slide groove 4211B towards the second locking part 432, until the first locking part 4312 and the second locking part 432 engage, thereby installing the pneumatic device 42 in the mounting groove 411B. This can improve the connection stability between the pneumatic device 42 and the cup lid 41.

[0104] When it is necessary to disassemble the blower 42, the actuator 4311 is driven to move along the through groove 4211A into the housing 421, and the first locking part 4312 is driven to move along the slide groove 4211B away from the second locking part 432 until the first locking part 4312 disengages from the second locking part 432, and the housing 421 moves away from the cup lid 41, so that the blower 42 disengages from the cup lid 41, thereby facilitating the separate cleaning of the cup lid 41, reducing the probability of liquid entering the blower 42, and giving the blower 42 a longer service life, which in turn gives the food processor 1 a longer service life.

[0105] Please refer to Figure 1 , Figure 7-9 Furthermore, the snap-fit ​​structure 43 also includes a limiting member 434 and a second elastic member 435. The limiting member 434 is disposed inside the housing 421; the second elastic member 435 is disposed inside the housing 421, and the two ends of the second elastic member 435 abut against the limiting member 434 and the actuating part 4311, respectively.

[0106] When installing the pneumatic device 42, press the actuating part 4311 so that the actuating part 4311 drives the first locking part 4312 to move into the housing 421, and causes the second elastic member 435 to undergo elastic deformation, so that the second elastic member 435 has elastic potential energy to engage the first locking part 4312 and the second locking part 432. Move the housing 421 until the housing 421 is embedded in the mounting groove 411B, release the actuating part 4311, and the second elastic member 435 pushes the first locking part 4312 and the second locking part 432 to engage, thereby improving the installation efficiency of the pneumatic device 42.

[0107] It is understood that the second elastic element 435 can be at least one of a spring, an elastic metal sheet, and an elastic rubber strip. In other embodiments, the second elastic element 435 can also be in other forms. In the embodiments of this application, the specific form of the second elastic element 435 is not limited.

[0108] Please refer to Figure 1 , Figure 7-9 Furthermore, the first engaging portion 4312 has an inclined surface 4312A. When installing the pneumatic device 42, the housing 421 is moved until the inclined surface 4312A abuts against the opening of the mounting groove 411B. The housing 421 continues to move into the mounting groove 411B, causing the first engaging portion 4312 to move away from the second engaging portion 432, and causing the second elastic member 435 to undergo elastic deformation. Then, the second elastic member 435 can push the first engaging portion 4312 to engage with the second engaging portion 432, thereby further improving the installation efficiency of the pneumatic device 42.

[0109] It is understandable that the first snap-fit ​​part 4312 may also have an arc surface, which can abut against the groove of the mounting groove 411B, and can also improve the installation efficiency of the pneumatic device 42.

[0110] It is understood that the inclined surface 4312A and the arc surface can also be provided in the groove of the mounting slot 411B, which can also push the first snap-fit ​​part 4312 to move away from the second snap-fit ​​part 432, and can also improve the installation efficiency of the pneumatic device 42. Further details are not provided in the embodiments of this application.

[0111] Please refer to Figure 5 , Figure 8 and Figure 9In one specific embodiment, the snap-fit ​​structure 43 further includes a second snap-fit ​​member 436 and a third snap-fit ​​member 437. The second snap-fit ​​member 436 is disposed on the periphery of the housing 421 and is spaced apart from the actuating part 4311 and the first snap-fit ​​part 4312. The third snap-fit ​​member 437 is disposed on the side wall of the mounting groove 411B and is spaced apart from the second snap-fit ​​part 432. The third snap-fit ​​member 437 can snap-fit ​​with the second snap-fit ​​member 436, thereby further improving the connection stability between the cup lid 41 and the pneumatic device 42.

[0112] It is understood that the second card connector 436 can be disposed on the opposite side of the first card connector 4312, or on one side of the first card connector 4312. In this embodiment, the specific location of the second card connector 436 within the housing 421 is not limited.

[0113] Please refer to Figure 4 and Figure 10 In another embodiment of detachable connection, a magnetic structure 44 is provided between the fan device 42 and the cup lid 41, which facilitates the disassembly of the fan device 42 and improves the connection stability between the fan device 42 and the cup lid 41, so that the fan device 42 can blow airflow into the receiving cavity 2A, thereby preventing bubbles or food from overflowing from the opening 2B.

[0114] It is understood that the magnetic structure 44 can be disposed on the side of the cup lid 41 away from the cup body assembly 2 to mount the fan device 42 on the side of the cup lid 41 away from the cup body assembly 2. Exemplarily, the fan device 42 can be magnetically mounted on the surface of the cup lid 41 away from the cup body assembly 2. It is also understood that the magnetic structure 44 can be disposed on the side of the cup lid 41 to mount the fan device 42 on the side of the cup lid 41. In this embodiment, the position of the magnetic structure 44 is not specifically limited.

[0115] Please refer to Figure 10 In one specific embodiment, the magnetic attraction structure 44 is disposed between the groove wall of the mounting groove 411B and the housing 421.

[0116] Please refer to Figure 9 Specifically, the magnetic structure 44 includes a first magnetic element 441 and a second magnetic element 442. The first magnetic element 441 is disposed on the housing 421; the second magnetic element 442 is disposed on the groove wall of the mounting groove 411B and can be magnetically connected with the first magnetic element 441, thereby attracting the fan device 42 to the mounting groove 411B to improve the connection stability between the fan device 42 and the cup lid 41.

[0117] For example, the first magnetic element 441 can be disposed at the bottom of the housing 421, and the second magnetic element can be disposed at the bottom wall of the mounting groove 411B. It is understood that the first magnetic element 441 can also be disposed on the side of the housing 421, and the second magnetic element can be disposed on the side wall of the mounting groove 411B. It is understood that at least one of the first magnetic element 441 and the second magnetic element 442 is a magnet. For example, at least one of the first magnetic element 441 and the second magnetic element 442 is a permanent magnet.

[0118] Please refer to Figure 4 and Figure 10 Furthermore, in addition to the magnetic attraction structure 44 between the blower 42 and the cup lid 41, a second snap-fit ​​member 436 is also provided on the periphery of the housing 421, and is spaced apart from the first magnetic member 441; a third snap-fit ​​member 437 is also provided on the side wall of the mounting groove 411B, and is spaced apart from the second magnetic member 442. The third snap-fit ​​member 437 can snap into the second snap-fit ​​member 436, which can further improve the stability of the magnetic attraction connection between the blower 42 and the cup lid 41, reduce the probability of the blower 42 detaching from the cup lid 41, and thus ensure that the blower 42 can blow air into the receiving cavity 2A to prevent air bubbles or food from overflowing from the opening 2B.

[0119] It is understandable that when the pneumatic device 42 and the cup lid 41 are detachably connected as described above, the upper surface of the cup lid 41 is provided with a mounting groove 411B. It should be noted that when the pneumatic device 42 and the cup lid 41 are magnetically connected, the cup lid 41 may not be provided with a mounting groove 411B. For example, the cup lid 41 can fix the pneumatic device 42 to the outer surface of the cup lid 41 through a magnetic attraction structure 44. In this case, the cup lid 41 can also be provided with a positioning structure such as a column to assist in positioning the pneumatic device 42.

[0120] Please refer to Figure 4 , Figure 5 and Figure 11 In another detachable connection embodiment, a flexible abutment structure 45 is provided between the housing 421 and the groove wall of the mounting groove 411B, so that after the housing 421 is installed in the mounting groove 411B, the flexible abutment structure 45 deforms to increase the contact area between the housing 421 and the mounting groove 411B, and to form an interference fit between the housing 421 and the cup lid 41, thereby improving the connection stability between the pneumatic device 42 and the cup lid 41.

[0121] Please refer to Figure 4 , Figure 5 and Figure 11In one specific embodiment, the flexible abutment structure 45 includes a first flexible abutment member 451, which is disposed on the outer periphery of the housing 421 for abutting against the sidewall of the mounting groove 411B. Exemplarily, the first flexible abutment member 451 can be a rubber ring. It is understood that the first flexible abutment member 451 can be annular. It is also understood that the first flexible abutment member 451 can include a plurality of first flexible abutment portions, with adjacent first flexible abutment portions spaced apart, and the plurality of first flexible abutment portions circumferentially disposed on the outer periphery of the housing 421.

[0122] Please refer to Figure 4 , Figure 5 and Figure 11 In another specific embodiment, the flexible abutment structure 45 includes a second flexible abutment member (not shown in the figure), which is disposed on the sidewall of the mounting groove 411B for abutting against the outer periphery of the housing 421. Exemplarily, the second flexible abutment member can be a rubber ring. It is understood that the second flexible abutment member can be annular. It is understood that the second flexible abutment member can include multiple second flexible abutment portions, with adjacent second flexible abutment portions spaced apart, and the multiple second flexible abutment portions circumferentially disposed around the outer periphery of the housing 421.

[0123] In another specific embodiment, a first flexible abutment 451 is provided on the outer periphery of the housing 421, and a second flexible abutment is provided on the side wall of the mounting groove 411B. After the housing 421 is installed in the mounting groove 411B, the first flexible abutment 451 abuts against the side wall of the mounting groove 411B, and the second flexible abutment abuts against the outer periphery of the housing 421. This can increase the contact area between the housing 421 and the mounting groove 411B, and make the housing 421 and the cup lid 41 form an interference fit, thereby improving the connection stability between the pneumatic device 42 and the cup lid 41.

[0124] The above description exemplifies several specific detachable connection implementations between the pneumatic device 42 and the cup lid 41. It is understood that, besides the methods described in the above embodiments, other forms of detachable connection between the pneumatic device 42 and the cup lid 41 can also be used, such as the insertion and mating of pins and holes. This application does not limit this. In other embodiments, the pneumatic device 42 and the cup lid 41 can also be connected in a non-detachable manner. For example, the housing 421 can be bonded and welded to the cup lid 41; alternatively, the housing 421 can be integrally formed with the cup lid 41. For example, both the housing 421 and the cup lid 41 can be made of plastic, and they can be integrally formed using a two-color injection molding process. The pneumatic device 42 can be modularly assembled before the cup lid 41 is formed, thereby improving the production efficiency of the cup lid assembly 4.

[0125] Please refer to Figure 4 , Figure 7 , Figure 12-14 It is understandable that fan 422 can pass through duct 423A (please refer to...) Figure 13 The fan 422 is connected to the air inlet 4211D so that it can blow air into the receiving cavity 2A to prevent air bubbles or food from overflowing from the opening 2B. For example, the fan 422 can be connected to the air inlet 4211D via a pipe, or the fan 422 can be connected to the air inlet 411A via a pipe through the air inlet 4211D, so that it can blow air into the receiving cavity 2A.

[0126] Please refer to Figure 8 and Figure 12 In one specific embodiment, the housing 421 forms a receiving cavity 4211C, and the housing 421 also has an air intake 4211E. A fan 422 is located within the receiving cavity 4211C. The fan 422 drives airflow to be drawn into the receiving cavity 4211C through the air intake 4211E and blown out through the air outlet 4211D. The housing 421 provides all-around protection for the fan 422, reducing the probability of damage to the fan 422 and thus extending its service life, consequently extending the service life of the pneumatic device 42. It should be noted that the fan 422 can be a centrifugal fan, an axial fan, or other similar type; this application does not limit its application to this type.

[0127] It is understood that when the fan device 42 is installed on the top of the cover 411, the air outlet 4211D is located on the bottom surface of the housing 421 facing the cup lid 41, and the air inlet 411A is located on the top surface of the cup lid 41. When the fan device 42 is installed on the side of the cover 411, the air outlet 4211D is located on the side of the housing 421, and the air inlet 411A is located on the side of the cup lid 41. In this embodiment, the suction port 4211E is located on the side of the housing 421, the air outlet 4211D is located on the bottom surface of the housing 421 facing the cup lid 41, and the air inlet 411A is located on the bottom wall of the mounting groove 411B.

[0128] Please refer to Figure 8 , Figure 13 and Figure 14In one specific embodiment, the housing 421 includes an outer shell 4211 and a fan shroud 423. A receiving cavity 4211C is formed within the outer shell 4211, and the fan shroud 423 is disposed within the receiving cavity 4211C. The fan shroud 423 and the inner wall of the outer shell 4211 cooperate to form an air duct 423A, which connects the air outlet side of the fan 422 to the air outlet 4211D. The fan 422 can draw air in through the air inlet 4211E and blow airflow into the receiving cavity 2A through the air duct 423A and the air outlet 4211D. It is understood that the fan shroud 423 can also form the air duct 423A independently. The materials of the outer shell 4211 and the fan shroud 423 can be metal or plastic. In this embodiment, no specific limitation is made on the materials of the outer shell 4211 and the fan shroud 423.

[0129] As exemplarily shown in the accompanying drawings of this application, the fan 422 is a centrifugal fan. By combining the centrifugal fan with the fan shroud 423, the axial direction of the fan 422 can be set to the up-down direction. The airflow blown by the fan 422 is turned downward by the fan shroud 423 so as to blow towards the air outlet 4211D. It can be understood that the axial direction of the centrifugal fan is its thickness direction, and the size of the centrifugal fan in its thickness direction is relatively small. This helps to reduce the thickness of the entire pneumatic device 42, so that after the pneumatic device 42 is installed, its center of gravity will not be too high. This also helps to improve the stability of its operation after it is installed on the cup lid 41.

[0130] During operation, the food processor 1 typically first grinds and pulverizes the ingredients in the receiving cavity 2A, and then heats the pulverized ingredients. Since the air vent 4211D is connected to the air inlet 411A, there is a possibility that ingredients may splash and enter the air vent 4211D and the air duct 423A from the air inlet 411A during the food processor 1's grinding process. Therefore, the pneumatic device 42 of this application can further include a valve body structure, which is installed on the outer casing 4211 and used to block or open the air vent 4211D. In this way, by setting the valve body structure, the food processor 1 can block the air vent 4211D during the grinding process and open the air vent 4211D during the heating process. This satisfies the spill prevention requirement and also effectively avoids the possibility of ingredients splashing into the air duct 423A, thereby further improving the operational stability and service life of the pneumatic device 42.

[0131] Please refer to Figure 8 and Figure 12In one specific embodiment, the shroud 423 also has a clearance hole 423B. The valve body structure includes a first seal 424 and a drive member 425. The first seal 424 is disposed inside the housing 4211. The drive member 425 is connected to the housing 4211. The output shaft of the drive member 425 passes through the clearance hole 423B and is connected to the first seal 424 to drive the first seal 424 to move, so as to block or open the air outlet 4211D.

[0132] Please refer to Figure 8 and Figure 12 Specifically, when air needs to be blown into the receiving cavity 2A, the driving member 425 drives the first sealing member 424 to move away from the air blowing port 4211D to open the air blowing port 4211D, thereby facilitating the airflow to enter the receiving cavity 2A through the air blowing port 4211D. When air is not needed to be blown into the receiving cavity 2A, the drive member 425 drives the first seal member 424 to move towards the air outlet 4211D until the first seal member 424 abuts against the inner wall of the receiving cavity 4211C and covers the air outlet 4211D, thereby sealing the air outlet 4211D. This prevents food or liquid from entering the receiving cavity 4211C through the air outlet 4211D during the stirring or crushing process of the cup assembly 2. It also prevents water vapor generated during the heating process from entering the receiving cavity 4211C through the air outlet 4211D, thereby reducing the probability of damage to the fan 422 and the drive member 425. This allows the fan 422 and the drive member 425 to have a longer service life, which in turn allows the food processor 1 to have a longer service life.

[0133] For example, the first seal 424 can be made of a flexible material, such as rubber, polyurethane, or polytetrafluoroethylene, so that the first seal 424 can undergo elastic deformation when it abuts against the receiving cavity 4211C, thereby sealing the air outlet 4211D. In other embodiments, the first seal 424 can also be made of other materials. Further details are not provided in this embodiment. The drive element 425 can be a linear motor or an electric actuator; the specific form of the drive element 425 is not limited in this embodiment.

[0134] Please refer to Figure 8 , Figure 13 and Figure 14 In one specific embodiment, the driving component 425 may include an electromagnetic coil 4251 and an electromagnet shaft 4252. The electromagnetic coil 4251 is disposed on the side of the fan cover 423 away from the air outlet 4211D. The electromagnet shaft 4252 passes through the electromagnetic coil 4251 and is able to move axially relative to the electromagnetic coil 4251. One end of the electromagnet shaft 4252 passes through the clearance hole 423B and is connected to the first seal 424. The wind-driven device 42 also includes a first elastic element 426, which is connected to the first seal 424.

[0135] Please refer to Figure 14 Specifically, when air needs to be blown into the receiving cavity 2A, the electromagnetic coil 4251 is energized, causing the electromagnet shaft 4252 to move away from the air outlet 4211D relative to the electromagnetic coil 4251. This causes the first sealing member 424 to move away from the air outlet 4211D, and causes the first elastic member 426 to undergo elastic deformation. This gives the first elastic member 426 the elastic potential energy to drive the first sealing member 424 to move closer to the air outlet 4211D, thereby opening the air outlet 4211D.

[0136] Please refer to Figure 13 When it is not necessary to blow air into the receiving cavity 2A, the electromagnetic coil 4251 is de-energized, and the first elastic member 426 pushes the first sealing member 424 to move towards the air outlet 4211D until the first sealing member 424 abuts against the inner wall of the receiving cavity 4211C and covers the air outlet 4211D, thereby sealing the air outlet 4211D.

[0137] It is understood that in other embodiments, when it is not necessary to blow air into the receiving cavity 2A, the electromagnetic coil 4251 is energized, so that the electromagnet shaft 4252 moves relative to the electromagnetic coil 4251 towards the air outlet 4211D, thereby driving the first sealing member 424 towards the air outlet 4211D and causing the first elastic member 426 to undergo elastic deformation, thereby blocking the air outlet 4211D; when it is necessary to blow air into the receiving cavity 2A, the electromagnetic coil 4251 is de-energized, and the first elastic member 426 causes the first sealing member 424 to move away from the air outlet 4211D, so as to open the air outlet 4211D.

[0138] It is understood that the first elastic element 426 can be at least one of a spring, an elastic metal sheet, and an elastic rubber strip. In this embodiment, the first elastic element 426 is a spring. The first elastic element 426 is sleeved around the periphery of the electromagnet shaft 4252, which can reduce the radial deformation of the first elastic element 426 to ensure that the first elastic element 426 can push the first seal 424 to move and block the air outlet 4211D. One end of the first elastic element 426 is connected to the first seal 424 and can also be connected to the end platform of the electromagnet shaft 4252. The other end can be connected to the bracket of the electromagnetic coil 4251 and can also be connected to the outer casing 4211.

[0139] The valve body structure illustrated above is in the form of a solenoid valve, and the drive unit 425 is located on the side of the fan shroud 423 facing away from the air outlet 4211D, thereby effectively reducing the possibility of food splashing onto the drive unit 425. This arrangement can improve the operational stability of the drive unit 425. It should be noted that the above description refers to an electrically driven valve body structure, but the valve body structure in the pneumatic device 42 of this application can also be manually driven. For example, the valve body structure includes a valve, and the valve can be manually operated to block or open the air outlet 4211D. This application does not impose any limitations on this.

[0140] Please refer to Figure 8 , Figure 13 and Figure 14 The fan device 42 also includes a filter 427, which is connected to the housing 421 and located at the air intake 4211E. The filter 427 prevents impurities from entering the receiving cavity 4211C through the air intake 4211E, thereby reducing the probability of damage to the fan 422 and the drive component 425, thus extending the service life of the fan 422 and the drive component 425, and consequently extending the service life of the food processor 1.

[0141] It is understood that the filter screen 427 can be detachably connected to the housing 421 to facilitate the replacement of the filter screen 427, thereby enabling the filter screen 427 to filter impurities. In the embodiments of this application, the connection method between the filter screen 427 and the housing 421 includes, but is not limited to, screw connection and snap connection.

[0142] Furthermore, if the filter 427 and the housing 421 are detachably connected, this application may provide a slot (not shown in the figure) on the housing 4211. The slot is provided at the position of the air intake 4211E, and the filter 427 can be slidably inserted into the slot. This makes it convenient to remove the filter 427 from the slot for cleaning after long-term use.

[0143] Please refer to Figure 12 The outer shell 4211 includes a first shell portion 4212 and a second shell portion 4213 connected to the first shell portion 4212. The fan 422, the fan cover 423 and the drive component 425 are all sandwiched between the first shell portion 4212 and the second shell portion 4213, which can improve the connection stability between the fan 422, the fan cover 423 and the drive component 425 and the outer shell 4211.

[0144] Specifically, the outer casing 4211 also includes a first connecting portion 4214 and a second connecting portion 4215. The first connecting portion 4214 is connected to the first casing portion 4212, and the second connecting portion 4215 is connected to the second casing portion 4213. Both the first connecting portion 4214 and the second connecting portion 4215 are connected to the fan 422, the fan shroud 423, and the drive component 425. For example, one of the first connecting portion 4214 and the second connecting portion 4215 can be a positioning post, and the other of the first connecting portion 4214 and the second connecting portion 4215 can be an abutment block. The positioning post can pass through the positioning hole to facilitate the positioning of the fan 422, the fan shroud 423, and the drive component 425. The abutment block can abut against the surfaces of the fan 422, the fan shroud 423, and the drive component 425 to clamp the fan 422, the fan shroud 423, and the drive component 425. In other embodiments, the first connecting part 4214 and the second connecting part 4215 can also be abutting blocks, which can also clamp the fan 422, the shroud 423 and the drive member 425 to improve the connection stability between the fan 422, the shroud 423 and the drive member 425 and the housing 4211.

[0145] It is understandable that the first housing part 4212 can be detachably connected to the second housing part 4213 so that the receiving cavity 4211C can be opened easily when the fan 422, the fan cover 423 and the drive component 425 are damaged, thereby improving the efficiency of maintenance and replacement of the fan 422, the fan cover 423 and the drive component 425 and reducing maintenance costs.

[0146] Please refer to Figure 5 and Figure 8 The housing 421 includes a first region 421A, a receiving cavity 4211C, an air duct 423A, a fan 422, a fan cover 423, and a drive component 425, all of which are disposed in the first region 421A. Along the thickness direction of the housing 421, the orthographic projection of the first region 421A is elliptical, which can save external space while satisfying the internal structural settings, thereby improving the aesthetics of the fan device 42 and making the fan device 42 compact, so as to facilitate the assembly of the fan device 42 and the cup lid 41.

[0147] Please refer to Figure 5 and Figure 8It is understandable that, since the electromagnet shaft 4252 drives the first seal 424 to move, a large space needs to be formed within the receiving cavity 4211C to allow the electromagnet shaft 4252 to move. Based on this, the first housing portion 4212 also has a protrusion 42121 extending away from the second housing portion 4213. The protrusion 42121 has a clearance cavity 42121A, which communicates with the receiving cavity 4211C. The electromagnet shaft 4252 is at least partially disposed within the clearance cavity 42121A. When the electromagnetic coil 4251 is energized, causing the electromagnet shaft 4252 to move away from the air outlet 4211D relative to the electromagnetic coil 4251, the electromagnet shaft 4252 can move into the clearance cavity 42121A. This results in a thinner thickness in other parts of the housing 421, making the internal structure of the housing 421 more compact, thereby reducing the volume of the housing 421 and minimizing its space occupation.

[0148] Immediately, the first shell portion 4212 also has a deformation groove 4212A provided at the root of the protrusion 42121 to eliminate stress concentration at the root of the protrusion 42121, thereby reducing the probability of cracks in the first shell portion 4212 and thus enabling the pneumatic device 42 to have a longer service life.

[0149] Please refer to Figure 2 , Figure 3 and Figure 5 The wind-driven device 42 also includes a first electrical connector 428, which is electrically connected to the fan 422 and the drive unit 425. The first electrical connector 428 is connected to the housing 421 and exposed. The cup assembly 2 has a second electrical connector 23, which can be connected to the main unit 3. The first electrical connector 428 can be electrically connected to the second electrical connector 23 to supply power to the fan 422 and the drive unit 425.

[0150] Please refer to Figure 5 , Figure 8 and Figure 12 Specifically, the housing 421 also includes a second region 421B, which includes an upper cover 4216 and a lower cover 4217 connected to the upper cover 4216. The upper cover 4216 and the lower cover 4217 surround a receiving space (not shown in the figure). The receiving space is spaced apart from the receiving cavity 4211C. The lower cover 4217 has a through hole 4217B communicating with the receiving space. The first electrical connector 428 is disposed in the receiving space and exposed through the through hole 4217B to facilitate electrical connection with the second electrical connector 23.

[0151] Understandably, the second area 421B is also easy for the user to hold, thereby improving the ease of disassembly and assembly of the pneumatic device 42; and because the second area 421B is easy for the user to hold, when it is necessary to clean the housing 421, the user can hold the second area 421B to clean it, which can prevent liquid from wetting the first electrical connector 428, thereby reducing the probability of short circuit of the first electrical connector 428, so that the first electrical connector 428 can have a longer service life, and thus the food processor 1 can have a longer service life.

[0152] It is understood that the wind-driven device 42 may also include an energy storage battery, which is installed in the housing 421 and electrically connected to the fan 422 and the drive unit 425 to supply power to the fan 422 and the drive unit 425.

[0153] Please refer to Figure 2 and Figure 14 The cup lid 41 includes a lid body 411 and an extension 412. The lid body 411 is detachably connected to the housing 421. The extension 412 is connected to the lid body 411 and extends from the lid body 411 toward the cup assembly 2. The extension 412 has a clearance groove 412A, through which the first electrical connector 428 is exposed. By abutting against the handle of the cup assembly 2, the extension 412 can provide support for the cup lid 41, reducing the probability of damage to the first electrical connector 428 and the second electrical connector 23, thereby allowing the food processor 1 to have a longer service life.

[0154] Please refer to Figure 5 Specifically, the extension 412 includes a first side 4121, a second side 4122, a third side 4123, and a bottom 4124. The third side 4123 is located between the first side 4121 and the second side 4122. The first side 4121, the second side 4122, the third side 4123, and the bottom 4124 are surrounded by a connecting groove 412B, which communicates with the clearance groove 412A. The first electrical connector 428 is disposed in the connecting groove 412B and exposed through the clearance groove 412A.

[0155] Please refer to Figure 2 , Figure 3 and Figure 5Furthermore, the second side 4122 has a receiving groove 4122A on the side opposite to the first side 4121. The clearance groove is connected to the receiving groove 4122A. The portion of the first electrical connector 428 exposed in the clearance groove is located in the receiving groove 4122A. This reduces the probability of collision with the first electrical connector 428 during the installation, handling, and cleaning of the cup lid assembly 4, thereby reducing the probability of damage to the first electrical connector 428 and enabling the first electrical connector 428 to have a longer service life, which in turn enables the food processor 1 to have a longer service life.

[0156] Please refer to Figure 2 , Figure 3 and Figure 5 Correspondingly, a protrusion 24 is provided on the side of the cup body 20 facing the cup lid assembly 4. The second electrical connector 23 is provided on the protrusion 24. The shape of the protrusion 24 is adapted to the shape of the relief groove. When the protrusion 24 is embedded in the receiving groove 4122A, the first electrical connector 428 and the second electrical connector 23 are electrically connected. The surface of the protrusion 24 facing away from the first side 4121 is coplanar with the surface where the groove of the receiving groove 4122A is located, so that the cup lid 41 and the cup body 20 can form a whole, thereby improving the aesthetics of the food processor 1.

[0157] For example, the surface shared by the surface of the protrusion 24 away from the first side portion 4121 and the surface where the groove of the receiving groove 4122A is located can be a plane or a curved surface. In this embodiment, no specific limitation is made.

[0158] Please refer to Figure 2 For example, the first electrical connector 428 can be connected to the second electrical connector 23 along the vertical direction X, or the first electrical connector 428 can be connected to the second electrical connector 23 along the circumferential direction Y of the cup body 20. In this embodiment, the connection direction between the first electrical connector 428 and the second electrical connector 23 is not specifically limited.

[0159] Please refer to Figure 5 In one embodiment, the cup lid 41 further includes a second sealing member 413. The second sealing member 413 is connected to the lid body 411 and is disposed at the air inlet 411A. After the fan device 42 is installed into the mounting groove 411B, the second sealing member 413 can abut against the outer shell 4211 and deform to block the area between the bottom wall of the mounting groove 411B and the outer shell 4211 on the periphery of the air inlet 411A, so as to prevent water vapor from entering the gap between the bottom wall of the mounting groove 411B and the outer shell 4211, thereby reducing the probability of liquid entering the fan device 42 through the air outlet 4211D, so that the fan device 42 can have a longer service life, and thus the food processor 1 can have a longer service life.

[0160] Furthermore, the second seal 413 prevents water vapor from entering the gap between the bottom wall of the mounting groove 411B and the outer shell 4211, thereby preventing water vapor from condensing between them. This keeps the groove wall of the mounting groove 411B and the outer periphery of the outer shell 4211 dry, reducing the probability of bacterial growth and providing reliable protection for the user's health. It also eliminates the need for the user to clean the mounting groove 411B, thus improving the efficiency of cleaning the cup lid 41.

[0161] For example, the material of the second seal 413 can be a flexible material, such as rubber, polyurethane, and polytetrafluoroethylene, so that the second seal 413 can undergo elastic deformation when it comes into contact with the housing 4211 to fill the gap between the bottom wall of the mounting groove 411B and the housing 4211, and prevent water vapor from entering the gap between the bottom wall of the mounting groove 411B and the housing 4211.

[0162] Please refer to Figure 5 , Figure 6 and Figure 13 In one specific embodiment, the lid 411 is further provided with an exhaust port 411C, a flow channel 411D, and an air outlet 411E. The flow channel 411D connects the exhaust port 411C and the air outlet 411E. The exhaust port 411C is located on the side of the lid 41 away from the housing 421, and the air outlet 411E is located on the side of the lid 41 facing the housing 421. The exhaust port 411C, the flow channel 411D, and the air outlet 411E can guide the gas generated in the cup body 20 to be discharged, which can prevent the pressure in the receiving cavity 2A from being too high, thereby improving the safety of using the food processor 1.

[0163] Please refer to Figure 4 , Figure 5 and Figure 13 Furthermore, since the food in the receiving cavity 2A is rotated during the stirring and crushing process of the mixing module 22, the liquid level at the center of the opening 2B near the cup body 20 is lower than the liquid level at the center of the opening 2B away from the cup body 20. Based on this, the exhaust port 411C is closer to the center of the opening 2B of the cup body 20 than the air outlet 411E, which can reduce the probability of food splashing from the exhaust port 411C to the guide channel 411D and the air outlet 411E, thereby reducing the cleaning difficulty of the guide channel 411D and improving the cleaning efficiency of the cup lid 41 for the user.

[0164] Please refer to Figure 5 , Figure 6 and Figure 13In one specific embodiment, the cover 411 has a flow guide groove 411F and is detachably connected to the housing 421. The air inlet 411A, the exhaust port 411C, and the air outlet 411E are all provided on the cover 411. The flow guide groove 411F connects the exhaust port 411C and the air outlet 411E. The cup lid 41 also includes a cover plate 414, which is connected to the cover 411 and covers the opening of the flow guide groove 411F to form a flow guide channel 411D with the groove wall of the flow guide groove 411F. By removing the cover plate 414, the user can clean the flow guide channel 411D, thereby reducing the probability of bacterial growth in the flow guide channel 411D and providing reliable protection for the user's health.

[0165] Please refer to Figure 4 , Figure 5 and Figure 13 In one specific embodiment, the heating module 21 has a hot end region 21A and a cold end region 21B. When the food in the receiving cavity 2A boils, it will roll from the hot end region 21A to the cold end region 21B of the heating module 21. The bubbles are also mainly concentrated near the top of the cold end region 21B of the heating module 21. The projection of the air outlet 4211D on the heating module 21 is located in the cold end region 21B to improve the bubble breaking efficiency of the fan device 42, thereby preventing bubbles or food from overflowing from the opening 2B.

[0166] For example, when the heating module 21 includes a resistance heating wire, the resistance heating wire can be arranged around the bottom of the cup body 20. The two ends of the resistance heating wire are respectively connected to the positive and negative terminals of the power supply. At this time, the area near the two ends of the resistance heating wire is the cold end area 21B, and the rest is the hot end area 21A.

[0167] Please refer to Figure 3-5 In one specific embodiment, the cup lid assembly 4 may further include a sealing ring 46, which is disposed around the periphery of the lid body 411. When the lid body 411 is placed over the opening 2B, the sealing ring 46 abuts against the inner wall of the receiving cavity 2A, thereby ensuring a stable connection between the cup lid assembly 4 and the cup body 20 and preventing air bubbles or food from overflowing from the opening 2B. The sealing ring 46 may be made of a flexible material, such as rubber, polyurethane, or polytetrafluoroethylene.

[0168] Please refer to Figure 2 , Figure 3 , Figure 8 and Figure 15 This application also provides a method for controlling a food processor 1, including:

[0169] Step S10: Obtain the connection status between the wind-driven device 42 and the cup assembly 2.

[0170] In this embodiment of the application, when the food processor 1 selected by the user includes a heating program in its execution program, the controller can obtain the connection status between the first electrical connector 428 and the second electrical connector 23 through the second electrical connector 23.

[0171] Step S20: It is detected that the fan device 42 is normally connected to the cup assembly 2. When the temperature inside the cup assembly 2 rises to the preset temperature, the fan device 42 is controlled to blow air into the receiving cavity 2A.

[0172] In this embodiment, when the fan device 42 is detected to be normally connected to the cup assembly 2, and the temperature inside the cup assembly 2 rises to a preset temperature, the controller controls the electromagnetic coil 4251 to be energized, so that the electromagnet shaft 4252 moves away from the air outlet 4211D relative to the electromagnetic coil 4251, thereby driving the first sealing member 424 to move away from the air outlet 4211D, and causing the first elastic member 426 to undergo elastic deformation to open the air outlet 4211D; the controller controls the fan 422 to rotate, driving the airflow to be drawn into the receiving cavity 4211C through the air intake 4211E, and blown out from the air outlet 4211D to the receiving cavity 2A, so as to break the generated bubbles, thereby preventing bubbles or food from overflowing from the opening 2B.

[0173] It is understood that the preset temperature can be 90℃, 95℃, or 100℃. In other embodiments, the preset temperature can also be other temperatures, and a suitable temperature can be selected according to the processing needs of the food. In the embodiments of this application, there is no limitation on the preset temperature. The preset temperature can be detected by a temperature sensor disposed on the cup lid 41 or the cup body assembly 2.

[0174] It is understood that a normal connection between the pneumatic device 42 and the cup assembly 2 includes both the physical structural connection between the pneumatic device 42 and the cup assembly 2, and the electrical connection between the first electrical connector 428 and the second electrical connector 23. If either connection condition is not met, it constitutes a non-normal connection between the pneumatic device 42 and the cup assembly 2.

[0175] Step S30: If the fan device 42 is not detected to be properly connected to the cup body assembly 2, when the temperature inside the cup body assembly 2 rises to the preset temperature, control the heating module 21 to reduce the heating power.

[0176] In this embodiment of the application, no normal connection between the fan device 42 and the cup assembly 2 is detected. When the temperature inside the cup assembly 2 rises to the preset temperature, in order to prevent bubbles or food inside the cup assembly 2 from overflowing from the opening 2B, the heating module 21 can be controlled to reduce the heating power to eliminate the generated bubbles.

[0177] Please refer to Figure 2 , Figure 3 , Figure 8 and Figure 16 In one specific embodiment, when no normal connection between the fan 42 and the cup assembly 2 is detected, the food processor 1 control method may further include:

[0178] Step S40: If the fan device 42 is not detected to be properly connected to the cup body assembly 2, a prompt message is sent to the user when the temperature inside the cup body assembly 2 rises to the preset temperature.

[0179] In this embodiment, if the fan device 42 is not detected to be properly connected to the cup assembly 2, and the temperature inside the cup assembly 2 rises to a preset temperature, a prompt message can be sent to the user to remind them to install the fan device 42. The prompt message may include sound, indicator lights, and status icons.

[0180] In other embodiments, the food processor 1 can be connected to a smart home system. No connection between the fan 42 and the cup assembly 2 is detected. When the temperature inside the cup assembly 2 rises to a preset temperature, a voice prompt can be sent to the user via a speaker in the smart home system. Alternatively, a prompt can be sent directly or indirectly to the user's terminal device via the wireless communication module in the food processor 1. The wireless communication methods of the module include, but are not limited to, WLAN (Wireless Local Area Network), RFID (Radio Frequency Identification), NFC (Near Field Communication), ZigBee, Bluetooth, and infrared.

[0181] Please refer to Figure 2 , Figure 3 , Figure 8 and Figure 17 In one specific embodiment, after step S40, the food processor 1 control method further includes:

[0182] Step S41: Within a preset time period, if the fan device 42 is detected to be normally connected to the cup assembly 2, control the fan device 42 to blow air into the receiving cavity 2A.

[0183] In this embodiment, within a preset time period, if the controller detects that the fan 42 is normally connected to the cup assembly 2, it controls the electromagnetic coil 4251 to be energized, causing the electromagnet shaft 4252 to move away from the air outlet 4211D relative to the electromagnetic coil 4251. This causes the first sealing member 424 to move away from the air outlet 4211D, and causes the first elastic member 426 to undergo elastic deformation, thereby opening the air outlet 4211D. The controller controls the fan 422 to rotate, driving airflow to be drawn into the receiving cavity 4211C through the suction port 4211E, and blown out from the air outlet 4211D to the receiving cavity 2A, thereby breaking the generated air bubbles and preventing air bubbles or food from overflowing from the opening 2B. For example, the preset time period can be 30 seconds, 1 minute, 1 minute 30 seconds, or 2 minutes.

[0184] Step S42: If no normal connection between the fan device 42 and the cup body assembly 2 is detected within the preset time period, control the heating module 21 to reduce the heating power.

[0185] In this embodiment, if the controller does not detect a normal connection between the fan device 42 and the cup assembly 2 within a preset time period, it controls the heating module 21 to reduce the heating power to eliminate the generated bubbles, thereby preventing bubbles or food in the cup assembly 2 from overflowing from the opening 2B.

[0186] This application embodiment also provides a storage medium storing a control program for a food processor 1, which, when executed by a processor, implements the steps of a control method for the food processor 1.
