Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly to a food processor. Background Art

[0002] Food processors can perform operations such as whipping, stirring, mixing, and crushing of food ingredients for people, providing a lot of convenience to people's lives and playing an increasingly important role in people's lives. Currently, food processors equipped with valve body structures are highly favored by users. Through the setting of the valve body structure, after the food ingredients are processed, the processed food ingredients can be discharged outside the mixing cup through the valve body structure without the need to pour the mixing cup, making it more convenient to use. However, in some scenarios, when discharging fluid food ingredients, if the user accidentally operates and lifts the mixing cup, it will cause the fluid food ingredients to spill, resulting in the soiling of the use environment or the user's clothes. Moreover, when the fluid food ingredients are heated, there is also a risk of scalding the user. Therefore, it is necessary to improve the existing food processor to overcome the above problems.

[0053] In real life, when people use a food processor to process food ingredients to obtain fluid food ingredients, the fluid food ingredients are discharged through a discharge valve assembly installed on the mixing cup device of the food processor, or during the automatic cleaning process, the cleaning liquid is discharged from the discharge valve assembly. However, in actual use, there are often such situations. On the one hand, during the discharge of fluid food ingredients or cleaning liquid, the user is distracted by chatting or thinking about other things and directly lifts the mixing cup device. Such a misoperation causes the fluid food ingredients or cleaning liquid to spill onto the use environment or the user's clothes, resulting in dirt. On the other hand, there may be fluid food ingredients or cleaning liquid adhering to the inner wall of the mixing cup of the mixing cup device. The user mistakenly believes that the fluid food ingredients or cleaning liquid have been completely discharged. During the process of lifting the mixing cup device, due to shaking, the fluid food ingredients or cleaning liquid are discharged from the discharge valve assembly, which also causes the use environment or the user's clothes to be soiled. And in the above process, when the fluid food ingredients or cleaning liquid are heated, there is also a possibility of scalding the user.

[0054] To solve the problems existing in the use of the above food processor, please refer to Figures 1 to 3, this application provides a food processor. The food processor includes a main body 10 and a mixing cup device 20. The mixing cup device 20 is detachably installed on the main body 10. The mixing cup device 20 includes a mixing cup main body 30 and a discharge valve assembly 60 installed on the mixing cup main body 30. The mixing cup main body 30 is provided with a discharge port 511, and the discharge valve assembly 60 is installed on the mixing cup main body 30 and abuts against the discharge port 511. Among them, a locking structure S is further provided between the main body 10 and the mixing cup device 20. The locking structure S is used to lock the mixing cup device 20 on the main body 10 when the discharge valve assembly 60 is in the open state, and to enable the mixing cup device 20 to be separated from the main body 10 when the discharge valve assembly 60 is in the closed state.

[0055] The host 10 includes a housing 110, a rotating motor 120 installed in the housing 110, a main control board, a power board, a cooling fan, and a control panel installed on the housing 110. The power board, the rotating motor 120, and the control panel are electrically connected to the main control board. The power board is connected to the external mains through a plug to provide power for the entire host 10. The user can input control instructions through the control panel, and the main control board controls the working state of the rotating motor 120 and other components through the control instructions to achieve different working modes. In one embodiment, a receiving groove 111 is formed on the housing 110, and the lower part of the mixing cup device 20 is placed in the receiving groove 111. The rotating motor 120 is provided with a rotating shaft upward, and the part of the rotating shaft located in the receiving groove 111 is provided with a lower connector, and the lower part of the mixing cup device 20 is provided with a lower connector. After the mixing cup device 20 is installed in the receiving groove 111, the upper connector and the lower connector are coupled in transmission, so that the power of the rotating motor 120 can be transmitted to the mixing cup device 20 to achieve the whipping of the food in the mixing cup device 20. In one embodiment, the food processor is further provided with a water tank 910 on the main unit 10 and a water pump, a water pipe connecting the water pump and the water tank 910, and a nozzle connected to the water pipe are further provided in the housing 110. When the food processor is in use, the water in the water tank 910 is pumped by the water pump and transported to the mixing cup device 20 to provide liquid for the mixing cup device 20 to beat the food or automatically clean the food. In order to avoid backflow during the food processing, a one-way valve can be provided on the water pipe, and the one-way valve is conducted in the direction from the water tank 910 to the mixing cup device 20. The mixing cup device 20 of the present application can be separated from the main unit 10, so the nozzle can be provided on the mixing cup device 20, and a joint is also provided on the housing 110. When the mixing cup device 20 is installed in the receiving groove 111 of the main unit 10, the joint and the nozzle are connected and connected. In one configuration, the water tank 910 and the housing 110 are separated, and the water tank 910 is detachably mounted on the housing 110. The detachable connection between the water tank 910 and the housing 110 may include, but is not limited to, snap-on, magnetic, plug-in, etc. Such a configuration is conducive to removing the water tank 910 for cleaning and water addition. In another configuration, the water tank 910 may be fixedly connected to the housing 110 or may not be detachable, or the water tank 910 may be formed in the housing 110 and the housing 110 is an integral structure. Such a configuration is conducive to structural stability and is easy to carry. In other configurations, the water tank 910 may not be provided, and water may be added directly from above the mixing cup device 20.

[0056] The present application may also form a support platform 112 under the housing 110 located below the discharge valve assembly 60 , and during use by the user, a container such as a receiving cup 920 may be placed on the support platform 112 to receive the slurry discharged from the discharge valve assembly 60 .

[0057] That is, through the above settings, the food processor of the present application is convenient during the food production and cleaning processes. In order to avoid the dangerous situation that the user lifts the mixing cup device 20 during the opening process of the discharge valve assembly 60 mentioned above, a locking structure S is provided to ensure the convenience of use of the food processor of the present application while improving its safety performance.

[0058] Please refer to Figures 2 to 4 、 Figure 11 and Figure 12 , in an embodiment, the discharge valve assembly 60 includes a valve body 70. The valve body 70 includes a discharge pipe 750 and a switch assembly 710. The discharge pipe 750 is connected to the discharge port 511. The switch assembly 710 includes a valve core 730 for controlling the on-off of the discharge pipe 750. The locking structure S includes a limiting portion 733 connected to the valve core 730 and a stop portion 113 connected to the housing 110. When the valve core 730 opens the discharge pipe 750, it drives the limiting portion 733 to contact the stop portion 113, and the stop portion 113 stops the limiting portion 733 in the direction in which the mixing cup device 20 detaches from the main body 10. When the valve core 730 closes the discharge pipe 750, it drives the limiting portion 733 and the stop portion 113 to separate, so that the locked state of the mixing cup device 20 and the main body 10 is released, and then the mixing cup device 20 can be separated from the main body 10. In some embodiments, the valve core 730 can close or conduct the discharge pipe 750 manually, that is, part of the valve core 730 is exposed or connected with an operating portion for exposure, so that the user can drive the valve core 730 to perform the on-off operation of the discharge pipe 750. In other embodiments, the power for the valve core 730 to close or conduct the discharge pipe 750 can also come from other power components, and the main control board of the main body 10 controls the power components to realize the automatic closing or conduction of the discharge pipe 750 by the valve core 730. The present application preferably adopts the scheme that the valve core 730 is automatically driven by a power component to close or conduct the discharge pipe 750, so that the whole food processor has the advantage of convenient use. The following content will also be further introduced with the scheme of automatically driving the valve core 730 to close or conduct the discharge pipe 750 by a power component.

[0059] Since the valve core 730 will generate corresponding movements during the process of opening or closing the discharge pipe 750, and the limiting part 733 is arranged on the valve core 730 and linked with it, the limiting part 733 can move until it contacts the stop part 113 during the process of the valve core 730 opening the discharge pipe 750. Moreover, the stop part 113 stops the limiting part 733 in the direction in which the mixing cup device 20 detaches from the main machine 10. Furthermore, it can effectively prevent the phenomenon that fluid food ingredients or cleaning liquid spill when the user lifts the mixing cup device 20 while the discharge valve assembly 60 is in the open state, effectively improving the use safety of the food processor. In the above solution, the valve core 730 realizes the opening and closing operations of the discharge pipe 750. It can be that the valve core 730 acts on the outside of the discharge pipe 750, and closes it by squeezing the discharge pipe 750 to deform so that the inner wall is closely attached. Then, when the squeezing external force is withdrawn, the discharge pipe 750 deforms and resumes conduction. It can also be realized by the valve core 730 acting on the inside of the discharge pipe 750 to directly block the internal channel of the discharge pipe 750. And the way of acting on the inside of the discharge pipe 750 can be that the valve core 730 extends in and out of the discharge pipe 750 by linear movement, or the valve core 730 rotates inside the discharge pipe 750. The specific way adopted in this application will be introduced in the following content. That is to say, the actions of the limiting part 733 and the stop part 113 in this application to contact and separate can be the way that the valve core 730 drives the limiting part 733 to rotate and contact the stop part 113, or the way that the valve core 730 drives the limiting part 733 to move linearly and contact the stop part 113. Please refer to the following content for specific details. In summary, through the above design in this application, by using the valve core 730 to drive the limiting part 733 to move, it can effectively realize the contact and separation of the limiting part 733 and the stop part 113 by using the structure inherent in the food processor with the automatic pulp discharging function, and realize the switching between the two states of locking the mixing cup device 20 on the main machine 10 and being able to separate from the main machine 10, thus improving the use safety of the food processor.

[0060] Understandably, based on the guiding ideology proposed in this application, we can also think that the limiting portion 733 and the stopping portion 113 in the locking structure S can also be arranged at other positions of the food processor, rather than being located on the valve core 730 and the housing 110 as mentioned in the above embodiments. At the same time, it can also be that the stopping portion 113 is an operating member that actively approaches the limiting portion 733 to achieve contact. On this basis, a power element can be arranged on the main body 10 and connected to the stopping portion 113, and a control program is written in the main control board. When the mixing cup device 20 is installed on the main body 10 and the discharge valve assembly 60 is in an open state, the main control board controls the power element to drive the stopping portion 113 to approach and contact the limiting portion 733, so as to stop the mixing cup device 20 from being removed from the main body 10. And when the valve core 730 closes the discharge pipe 750, the main control board simultaneously controls the power element to control the separation of the stopping portion 113 from the limiting portion 733, so that the mixing cup device 20 can be separated from the main body 10. That is to say, the valve core 730 is linked with the power element, and the contact and separation of the limiting portion 733 and the stopping portion 113 are realized in an electric control manner. Among them, the power element for driving the stopping portion 113 to act can include but is not limited to motors, cylinders, electromagnets, etc. At the same time, it can also be that the power element is located on the mixing cup device 20 to drive the limiting portion 733 to act, or it can also be that a power element is arranged in various ways in the mixing cup device 20 and the main body 10 to drive both the limiting portion 733 and the stopping portion 113 to act and to achieve contact and separation. And since the solution of driving the limiting portion 733 to act with the valve core 730 to contact and separate from the stopping portion 113 does not require too many modifications to the existing food processor, it utilizes the structure of the food processor itself with a slurry discharge valve assembly, and has many advantages such as reliable structure and low cost. The following content will further introduce the solution in which the limiting portion 733 is connected to the valve core 730 and acts together with the valve core 730.

[0061] In one embodiment, the limiting portion 733 is a limiting hook connected to the valve core 730, the stopping portion 113 is a stopping rib formed by protruding inward from the groove wall of the accommodating groove 111, or the stopping portion 113 is a buckling groove formed on the groove wall of the accommodating groove 111. The discharge valve assembly 60 of the present application further includes a valve housing 80, the valve housing 80 is connected to the main body 30 of the mixing cup, the discharge pipe 750 and the switch assembly 710 are both installed on the valve housing 80, and the limiting portion 733 extends out of the valve housing 80 and can be exposed by the main body 30 of the mixing cup. Among them, the discharge pipe 750 is formed with a discharge channel 761 and is provided with a feed port 762, a discharge port 763 and an insertion port 771 communicating with the discharge channel 761, and the feed port 762 is docked with the discharge port 511. The switch assembly 710 includes a driving assembly 720, the driving assembly 720 is detachably installed on the valve housing 80, the valve core 730 is connected to the driving assembly 720, and the valve core 730 enters and exits the discharge pipe 750 through the insertion port 771 under the drive of the driving assembly 720 to open or block the discharge channel 761. Among them, the valve core 730 includes a valve core main body 731, the limiting portion 733 is connected to the outside of the valve core main body 731, and the limiting portion 733 and the valve core main body 731 may be an integral structure or a split structure. In the case of the two being an integral structure, the materials of the valve core main body 731 and the limiting portion 733 may be different. Since the valve core main body 731 needs to be able to directly block the discharge channel 761, the valve core main body 731 may be made of a material with a certain elasticity, such as silicone, rubber and other materials, while the limiting portion 733 needs to be in contact and cooperation with the stopping portion 113 to prevent the mixing cup device 20 from separating, so the limiting portion 733 may be made of a hard material, such as hard plastic, metal, etc., and the valve core main body 731 and the limiting portion 733 may be formed into an integral structure by welding or secondary injection molding.

[0062] The drive assembly 720 is in driving connection with the valve core body 731. In this application, the drive assembly 720 drives the valve core 730 to extend into and out of the discharge pipe 750 in a linear motion manner to close or conduct the discharge channel 761 in the discharge pipe 750. Among them, after the discharge valve assembly 60 is installed on the mixing cup body 30 through the valve housing 80, the central axis of the valve core 730 is collinear with the central axis of the drive assembly 721. And the central axis of the drive assembly 721 is inclined at an angle with the vertical direction, and the central axis of the valve core 730 is inclined at an acute angle with the vertical direction. In an embodiment, the included angle between the central axis of the valve core 730 and the vertical direction ranges from 20° to 60°. Specifically, after the mixing cup device 20 is installed in the receiving groove 111 of the main machine 10, the central axis of the valve core 730 is in a state of gradually approaching the groove wall of the receiving groove 111 from bottom to top. Then, during the linear reciprocating motion of the valve core 730, the limiting part 733 moves obliquely upward and contacts the stopping part 113, and the limiting part 733 moves obliquely downward and separates from the stopping part 113. And the limiting part 733 is set as a limiting hook, while the stopping part 113 is a stopping rib protruding from the groove wall of the receiving groove 111 or a structure with a buckle groove formed on the groove wall of the receiving groove 111. Driven by the drive assembly 720, the valve core 730 drives the limiting hook to insert below the stopping rib or extend into the position in the buckle groove and contact it, and just move in the reverse direction when separating. Such a design has a simple structure and a reliable locking process. It can be understood that in the above content, the discharge valve assembly 60 may not be provided with the valve housing 80. Among them, the discharge pipe 750 and the switch assembly 710 in the valve body 70 can be installed and fixed by the structure in the mixing cup device 20, so that the central axis of the valve core 730 is in a state of being at an acute angle with the vertical direction. In addition, for the structural forms of the limiting part 733 and the stopping part 113, in addition to the structural forms mentioned in the above content, other structural forms that form blocking and separation are also possible, and this application does not limit this.

[0063] The above content introduces that the food processor of this application has the advantage of safe use by setting the locking structure S. However, the advantages of the food processor of this application are not limited to this. And the food processor of this application also has the advantage of a compact structure when realizing the above-mentioned safe use function. This advantage is reflected in the specific structure of the mixing cup device 20 in one aspect. Next, the structure of a new mixing cup device 20 proposed by this application will be specifically introduced.

[0064] Please refer to Figures 1 to 5, the stirring cup device 20 of the present application includes a stirring cup main body 30. The stirring cup main body 30 includes a stirring cup assembly 40 and a cup base assembly 50. The stirring cup assembly 40 includes a stirring cup 410 and a handle 420 installed on the stirring cup 410. The cup base assembly 50 is installed at the bottom of the stirring cup 410 to cooperate with the stirring cup 410 to form a stirring cavity. The cup base assembly 50 is provided with a discharge port 511 communicating with the stirring cavity. The cup base assembly 50 and the handle 420 cooperate to form an installation space communicating the discharge port 511 and the outside. The discharge valve assembly 60 is located in the installation space. The valve housing 80 of the discharge valve assembly 60 is detachably connected to the cup base assembly 50 and docks with the discharge port 511. In one setting mode, both the discharge pipe 750 and the limiting portion 733 can be exposed by the cup base assembly 50. That is, in the solution of the present application, the important components in the discharge valve assembly 60 are covered and hidden by the cup base assembly 50 and the handle 420, and only the discharge pipe 750 for realizing the basic discharge function and the limiting portion 733 for realizing the safety function are exposed. Thus, during the use process, when the user repeatedly places or lifts the stirring cup device 20, since the discharge valve assembly 60 is protected, its main structure will not be collided by external foreign objects. Therefore, during the use process of the stirring cup device 20, the structural stability and safety are better, and the structural integrity of the stirring cup device 20 observed from the outside is higher and more compact, giving people a beautiful feeling. At the same time, due to the design of hiding the main components of the discharge valve assembly 60, external dust and other foreign objects are not easily deposited on the discharge valve assembly 60, which is also beneficial to improving the hygiene, not easy to breed bacteria, and improving the food safety performance. It can be understood that in other setting modes, both the discharge pipe 750 and the limiting portion 733 can also be hidden, or one of them is exposed while the other is hidden. Here, being exposed means being visible from the outside.

[0065] The cup holder assembly 50 includes a cutter head 510 and a housing structure 540. The cutter head 510 is provided with a discharge port 511. The housing structure 540 is connected to the mixing cup 410 and fixes the cutter head 510 at the bottom of the mixing cup 410. The valve housing 80 is detachably connected to the cutter head 510. The discharge pipe 750 and the limiting portion 733 can both be exposed by the housing structure 540. The mixing cup 410 of the present application can be made of glass, metal (such as stainless steel), etc. The mixing cup 410 is provided with openings at both the top and bottom. A sealing ring is clamped between the mixing cup 410 and the cutter head 510. After the housing structure 540 is connected to the bottom of the mixing cup 410, the cutter head 510 is clamped at the bottom of the mixing cup 410, and the mixing cup 410 and the cutter head 510 also clamp the sealing ring to prevent leakage during the process of whipping food materials. Specifically, a spiral protrusion can be provided on the outer wall surface of the bottom of the mixing cup 410, and a connecting lug structure is also formed on the housing structure 540. The spiral protrusion and the connecting lug are clamped together. In this embodiment, the discharge valve assembly 60 is received through the cooperation of the housing structure 540 and the handle 420, which can effectively prevent the discharge valve assembly 60 from being collided by foreign objects during the process of lifting and carrying the mixing cup device 20. Such a layout is relatively reasonable and the structural stability is high.

[0066] Specifically, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 , the upper part of the housing structure 540 is spliced with the lower part of the handle 420. The cutter head 510, the housing structure 540 and the handle 420 jointly define an installation space. The housing structure 540 is provided with a relief opening communicating with the outside. The discharge pipe 750 and the limiting portion 733 can be exposed by the relief opening. By splicing the upper part of the housing structure 540 with the lower part of the handle 420, the gap exposed by the mixing cup device 20 is smaller, and it is more difficult for external foreign objects to enter the interior of the mixing cup device 20 and fall on the discharge valve assembly 60, thereby further improving the compactness, safety and hygiene of the overall structure of the mixing cup device 20.

[0067] In an embodiment, please refer to Figure 4 , Figure 5 and Figure 7, the housing structure 540 includes a cup base 550 and a cover assembly 560. The cup base 550 covers the outside of the cutter head 510 and is connected to the mixing cup 410 to relatively lock the cutter head 510 to the mixing cup 410. The relief opening includes a first relief opening 551 opened at the position of the cup base 550 corresponding to the discharge port 511, a second relief opening 573 and a third relief opening 574 provided on the cover assembly 560. A part of the valve housing 80 extends into the first relief opening 551 and is detachably connected to the cutter head 510. The discharge pipe 750 extends towards the second relief opening 573. Wherein, when the discharge pipe 750 can be exposed from the second relief opening 573, in this way, during the discharge process of the discharge pipe 750, the liquid is not easily splashed and remains on the cover assembly 560. The limiting part 733 can extend out of the third relief opening 574. In this application, the cup base 550 mainly functions to fix the cutter head 510, and the cover assembly 560 is connected to the cup base 550 to cover the outside of the cup base 550 and realize the accommodation of the main structure of the discharge valve assembly 60. Such a design ensures the overall structural stability and high compactness of the mixing cup device 20, and is also conducive to modular assembly and improving production efficiency. The cup base 550 of this application is provided with the structure of the connecting convex block in the above content. The cover assembly 560 has a structure with an open upper part and a closed lower part. The cover assembly 560 and the cup base 550 can be connected by screws and screw columns provided on the two to achieve this. The second relief opening 573 and the third relief opening 574 are respectively provided on the bottom wall and the side wall of the cover assembly 560. With such a setting, basically, external foreign objects are very difficult to collide with the discharge valve assembly 60, and it is also very difficult for external foreign objects to enter the interior of the mixing cup device 20, causing dust to adhere to the discharge valve assembly 60, and the overall structure is more compact, presenting a simple and beautiful outer contour to consumers.

[0068] Furthermore, the cover assembly 560 includes a cup cover 570 and a bottom cover 580. The bottom cover 580 is fixedly connected to the cup base 550 and locks the cup cover 570 to the cup base 550. Among them, the cup cover 570 is a cylindrical shape with both ends penetrating, and the bottom cover 580 covers the bottom of the cup cover 570. In this application, the cup cover 570 and the cup base 550 are detachably connected. Specifically, threaded posts can be provided on the bottom cover 580, and threaded holes can be provided on the cup base 550. In this way, through a connecting member such as a screw or a bolt passing through the screw post and then connecting to the threaded hole, the bottom cover 580 can be covered on the bottom of the cup cover 570, and the cup cover 570 can be relatively locked to the cup base 550. Through the above settings of the housing structure 540 in this application, when the overall structure of the mixing cup device 20 is compact, it is also conducive to modular assembly. The specific assembly process can be as follows: After installing the handle 420 to the mixing cup 410, the mixing cup 410 can be turned over as a whole so that its bottom opening faces upward. After fixing the sealing ring to the cutter head 510, the cutter head 510 and the sealing ring are buckled on the opening at the bottom of the mixing cup 410. Then, the cup base 550 is installed and fixed to the bottom of the mixing cup 410 to fix the cutter head 510 to the mixing cup 410 together and clamp the sealing ring to achieve sealing. During this process, when the cup base 550 is installed, the first relief opening 551 on the cup base 550 should be aligned with the discharge port 511 of the cutter head 510. In this way, after installing the cup base 550, the discharge valve assembly 60 is passed through the first relief opening 551 and installed outside the cutter head 510, so that the discharge valve assembly 60 is preliminarily fixed. Then, corresponding wiring operations are carried out. Next, the cup cover 570 in the cover assembly 560 is covered outside the cup base 550 to house and hide the main structure of the discharge valve assembly 60. During this process, the second relief opening 573 and the third relief opening 574 on the cup cover 570 should respectively expose the discharge pipe 750 and the limiting portion 733. Finally, the bottom cover 580 is buckled on the port of the cup cover 570, and the bottom cover 580 is locked to the cutter head 510 through a connecting member to axially lock the cup cover 570 to the cup base 550 to form the assembly of the overall structure. From the content shown above, we can see that the mixing cup device 20 in this application can well adapt to modular assembly in the automated production process during production, and it is also relatively convenient during later disassembly, maintenance, and repair processes. Only need to perform reverse operations and open components such as the bottom cover 580 in sequence.

[0069] Through modular design, the mixing cup device 20 in this application achieves high assembly efficiency. In the case of a compact structure, it also has the characteristic of a stable installation structure. Especially for the discharge valve assembly 60, after the valve housing 80 of the discharge valve assembly 60 is fixed to the cutter head 510, the following design is also made to ensure that the discharge valve assembly 60 has a relatively stable installation form to achieve the locking function in the above content. Please refer to Figure 5 and Figure 6In one embodiment, a valve housing positioning portion 830 is formed on the valve housing 80 , and a cup seat positioning portion 552 is provided on the cup seat 550 . The valve housing positioning portion 830 is snap-fitted with the cup seat positioning portion 552 . The cup seat positioning portion 552 is arranged near the first clearance port 551. In one arrangement, the cup seat positioning portion 552 can be a groove structure formed on the cup seat 550, and the valve housing positioning portion 830 is a columnar structure formed on the valve housing 80. The columnar valve housing positioning portion 830 is inserted into the groove structure, which can provide positioning for the discharge valve assembly 60 in the process of passing through the first clearance port 551 to connect with the cutter disc 510, thereby providing an automatic alignment connection reference for the valve housing 80 of the discharge valve assembly 60 and the cutter disc 510 during the installation process. This makes assembly more convenient and the installation structure of the discharge valve assembly 60 more stable. It can be understood that the structural form of the valve housing positioning portion 830 and the cup seat positioning portion 552 can also be the interchange of the above contents between the two, or other structural forms that can achieve preliminary positioning.

[0070] For further information, please refer to Figure 8 The cup cover 570 includes a barrel portion 571 and an overlap portion 572 protruding outward relative to the barrel portion 571, the barrel portion 571 is sleeved on the outside of the cup holder 550, the upper portion of the overlap portion 572 is spliced with the lower portion of the handle 420, the overlap portion 572 is provided with the second make way opening 573 and the third make way opening 574, wherein the second make way opening 573 is arranged at the bottom of the overlap portion 572, the third make way opening 574 is arranged at the side of the overlap portion 572, and the inner wall of the overlap portion 572 is also provided with a support portion 575, and the valve housing 80 is against the support portion 575. From the above content, we know that the cup cover 570 covers the outside of the cup holder 550 and partially accommodates the discharge valve assembly 60. The solution of the present application also provides a support portion 575 on the overlapping portion 572 of the cup cover 570, and the support portion 575 abuts against the side of the valve housing 80 away from the first clearance port 551. The cup holder 550 and the cup cover 570 achieve a clamping and positioning effect on the opposite sides of the valve housing 80. This can well ensure the stability of the installation structure of the discharge valve assembly 60, and it is not easy to shake during the movement of the valve core 730.

[0071] Please refer to Figure 2 , Figure 4 and Figure 5, the discharge pipe 750 of the present application is a flexible pipe, which can be made of, for example, silicone material or other materials with certain deformation characteristics. On the one hand, it is easier to manufacture the discharge pipe 750. On the other hand, when the valve core 730 enters and exits the discharge pipe 750, a better extrusion seal can be formed, and the assembly is also easier. In order to ensure that the discharge pipe 750 does not deform after long-term use and cause a change in the position of the second relief port 573, resulting in the solution spilling onto the cup cover 570 when discharging the liquid, a positioning groove 746 is formed at one end of the discharge pipe 750 close to the discharge port 763 in the present application. And a cup cover positioning portion 576 is provided on the inner wall of the bottom of the cup cover 570 close to the overlapping portion 572. The cup cover positioning portion 576 is in the shape of a rib, and the cup cover positioning portion 576 is snapped into the positioning groove 746. In this way, the cooperation of the positioning groove 746 and the cup cover positioning portion 576 can limit the posture of the discharge pipe 750 at the second relief port 573, ensuring that the slurry is smoothly discharged from the second relief port 573 during use.

[0072] The content introduced above explains the characteristics of the food processor, such as compact structure, convenient assembly and safe use, from the perspective of the mixing cup device 20. However, the advantages of the food processor of the present application are not limited to this. The food processor of the present application also has the advantage of easy cleaning. In terms of easy cleaning, on the one hand, it is reflected that the mixing cup device 20 is detachably installed on the main body 10, and it is also reflected by optimizing the design of the slurry discharge valve assembly to achieve easy cleaning.

[0073] First of all, as mentioned above, the slurry discharge valve assembly 60 of the present application is detachably connected to the cutter head 510, so that the slurry discharge valve assembly 60 can be easily detached and cleaned separately. Specifically, please refer to Figures 9 to 12, the valve housing 80 is provided with a first mounting portion 821, the cutter head 510 is provided with a second mounting portion, and the discharge valve assembly 60 is detachably connected to the cutter head 510 through the cooperation of a connecting member with the first mounting portion 821 and the second mounting portion. In this application, the cutter head 510 is a die-cast metal part. A stirring blade 520 and a blade seat for fixing the stirring blade 520 are mounted on the cutter head 510. And when the food processor has a heating function, a heating element 530 is also mounted on the cutter head 510, where the heating element 530 can be, but is not limited to, a heating tube, a heating wire, a heating film, etc. In one embodiment, the second mounting portion is a connecting column integrally formed with the cutter head 510, and a threaded hole is provided inside the connecting column. The first mounting portion 821 can be a mounting hole formed on the valve housing 80, and the mounting hole can be a through hole or a threaded hole. Then, during the installation process, a connecting member such as a screw or a bolt is passed through the first mounting hole and then locked to the second mounting portion, and such a structure is also relatively convenient for disassembly and assembly. And for the stability of the connection structure, three first mounting portions 821 and second mounting portions can be respectively provided and are arranged at intervals around the discharge port 511. Of course, this application does not limit the number of the first mounting portion 821 and the second mounting portion.

[0074] From the above content, we know that the discharge pipe 750 of this application is formed with a discharge channel 761 and is provided with a feed port 762, a discharge port 763, and an insertion port 771 communicating with the discharge channel 761. The feed port 762 is docked with the discharge port 511. The drive assembly 720 is detachably mounted on the valve housing 80. The valve core 730 is connected to the drive assembly 720. The valve core 730 enters and exits the discharge pipe 750 from the insertion port 771 under the drive of the drive assembly 720 to open or block the discharge channel 761. Among them, the drive assembly 720 includes a drive member 721 and a transmission member 722 detachably connected to the drive shaft of the drive member 721. The drive member 721 drives the valve core 730 to perform linear reciprocating motion through the transmission member 722. The valve housing 80 includes a valve seat 820 and a valve cover 810 that are detachably connected. The drive member 721 is detachably mounted on the valve seat 820, and the transmission member 722, the valve core 730, and the discharge pipe 750 are all arranged in the valve seat 820. That is, in this application, the valve housing 80 is divided into two parts, the valve cover 810 and the valve seat 820. The valve cover 810 and the valve seat 820 are detachably connected. The drive member 721 is mounted on the valve cover 810, and the valve core 730 and the discharge pipe 750 are all arranged in the valve seat 820. Thus, after the entire discharge valve assembly 60 is removed, the valve cover 810 and the drive member 721 can be removed together from the valve seat 820, and the remaining structure in the valve seat 820 can be directly washed with water. In this way, it is more convenient to clean while better protecting the drive member 721.

[0075] Please refer to again Figure 11 and Figure 12, in some setting modes, a first locking hole is provided on the valve seat 820, a second locking hole 812 is provided on the valve cover 810, and the valve seat 820 and the valve cover 810 are detachably connected through the cooperation of a connecting piece with the first locking hole and the second locking hole 812; and / or, one of the valve seat 820 and the valve cover 810 is provided with a buckle 811, and the other is provided with a buckling position. The valve seat 820 and the valve cover 810 are clamped through the cooperation of the buckle 811 and the buckling position. That is to say, the valve cover 810 and the valve seat 820 are connected by screws at one place and clamped at the other place, which makes the assembly more convenient and efficient.

[0076] In one embodiment, the driving member 721 is a driving motor, the transmission member 722 is a driving screw rod connected to the motor shaft of the driving motor, and the driving screw rod is threadedly connected to the valve core 730. In one embodiment, the driving screw rod and the motor shaft of the driving motor are detachably connected. In some setting modes, the driving screw rod is formed with a mounting hole, the motor shaft of the driving motor is formed with a connecting hole, and the driving screw rod is detachably connected to the motor shaft through the cooperation of a connecting piece with the mounting hole and the connecting hole. Such a setting has the advantage of facilitating the disassembly of the overall structure and making cleaning more convenient. The valve core body 731 of the valve core 730 is hollow inside, and a receiving cavity with an opening at one end is formed inside the valve core 730. Internal threads are formed on the inner wall of the receiving cavity, and the driving screw rod extends into the receiving cavity and is threadedly connected to the internal threads. Further, a guide groove 824 is further formed in the inner cavity of the valve seat 820, and the guide groove 824 extends in the length direction of the valve seat 820. An external guide protrusion 734 is connected to the outside of the valve core 730, and the guide protrusion 734 is snapped into the guide groove 824. When the driving motor drives the driving screw rod to rotate through the rotation of the motor shaft, due to the cooperation of the internal threads inside the valve core 730, the valve core 730 also has a tendency to rotate. And because of the limitation of the guide protrusion 734 and the guide groove 824, the valve core 730 can only move along the guide groove 824 and thus perform a reciprocating linear motion. In such a form, the installation space of the entire discharge valve assembly 60 is small, and the structure is relatively compact, especially capable of matching and realizing the compact structure characteristics of the mixing cup device 20 in the above content. It can be understood that in other embodiments, the combination form of the driving member 721 and the transmission member 722 can also be: the driving member 721 is a cylinder, and the transmission member 722 is the piston rod of the cylinder, or the driving member 721 is a motor, and the transmission member 722 is a pair of meshing gears and racks, or other combination forms that can be converted into linear motion. Considering the volume and economic cost, the present application preferably adopts the form that the driving member 721 is a driving motor and the transmission member 722 is a driving screw rod.

[0077] In one embodiment, to ensure the safety during the use of the drive motor, a sealing ring 780 is further sleeved outside the drive motor. The sealing ring 780 is clamped between the valve cover 810 and the drive motor. The sealing ring 780 can ensure that the drive motor is protected from water and moisture erosion during use. On the other hand, it can also play the role of shock absorption and noise reduction.

[0078] In one embodiment, the discharge valve assembly 60 further includes a position detector 740 for detecting the position of the valve core 730. The second relief opening 573 on the valve seat 820 forms a relief opening corresponding to the mounting bracket 732. The mounting bracket 732 extends out of the valve seat 820 through the relief opening. The position detector 740 is located outside the valve seat 820 and is mounted on the mounting bracket 732. In the above content, the limiting portion 733 is formed on the mounting bracket 732. In this application, the position detector 740 can be a magnet. Then, a sensor corresponding to the position detector 740 can be further provided on the mixing cup device 20 or on the main machine 10 to form the detection principle of a Hall sensor. By setting the position detector 740, a control signal can be effectively provided to the main control board to control the drive motor to drive the valve core 730 to extend into the discharge pipe 750 to an appropriate depth from the insertion port 771. Furthermore, while ensuring the stability of the structure, it can also ensure more reliability during the process of closing and opening the valve core 730. It can be understood that for the position detection of the valve core 730, it can also be in other forms, such as forming a microswitch, adopting the structural form of an optoelectronic sensor, etc. This application does not limit this.

[0079] Please refer to again Figure 11 and Figure 12, in one embodiment, the discharge pipe 750 includes a main pipe body 760 and an interface pipe 770 that are connected and communicate with each other. A discharge channel 761 is formed in the main pipe body 760, and a feed port 762 and a discharge port 763 are formed at both ends respectively. An insertion port 771 is formed in the interface pipe 770. The valve seat 820 is hollow inside and is provided with a first opening and a second opening that communicate with its inner cavity. The interface pipe 770 is received in the valve seat 820. One end of the main pipe body 760 where the feed port 762 is formed extends out of the valve seat 820 through the first opening, and the other end of the main pipe body 760 where the discharge port 763 is formed extends out of the valve seat 820 through the second opening. From the above content, we know that the discharge pipe 750 of the present application has a certain deformation ability. Therefore, by forming the valve seat 820 into a hollow structure, during the installation process, the discharge pipe 750 can be passed through the first opening and the second opening by extrusion, and one end of the discharge pipe 750 with the feed port 762 is exposed on one side of the valve seat 820 with the first opening, and one end with the discharge port 763 is exposed on one side of the valve seat 820 with the second opening. In this way, the discharge pipe 750 is mounted on the valve seat 820, and the interface pipe 770 is just located inside the valve seat 820 to allow the valve core 730 to be inserted to conduct and close the discharge pipe 750. Such installation is relatively convenient and the structure is also relatively compact. At the same time, since the valve core 730 is detachably arranged with the discharge pipe 750, during the cleaning process, the valve core 730 and the discharge pipe 750 can be disassembled respectively, so as to facilitate directly flushing the discharge pipe 750. In order to further improve the installation structure stability of the discharge pipe 750, a clamping groove 764 is further formed on the main pipe body 760 of the present application, and the side wall of the valve seat 820 at the first opening is clamped into the clamping groove 764. The setting of the clamping groove 764 further limits the discharge pipe 750 by the valve seat 820, so that the discharge pipe 750 is not likely to loosen when it is quickly clamped to the valve seat 820 in the above situation.

[0080] In order to improve the sealing performance, on the one hand, a first sealing rib 765 is provided on the inner wall of the main pipe body 760 at the position corresponding to the interface pipe 770. And / or, a second sealing rib 772 is provided on the inner wall of the interface pipe 770, and / or, a water retaining rib 767 surrounding the feed port 762 is provided on the end face of one end of the main pipe body 760 where the feed port 762 is formed.

[0081] Furthermore, for the convenience of flushing, after the discharge valve assembly 60 is installed, the center line of the discharge channel 761 in the discharge pipe 750 of the present application is a straight line and is inclined downward, and an angle A is formed between the center line of the discharge channel 761 and the vertical direction (refer to Figure 2), where 20° ≤ A ≤ 60°. When the included angle is too small, the angle that the main body 760 of the discharge pipe 750 and its feed port 762 need to turn is too large, which is not conducive to cleaning. When the included angle is too large, the lateral distance of the discharge valve assembly 60 is too large, affecting the installation space of other parts at the bottom of the mixing cup device 20, making the structure not very compact. Through this setting of the discharge pipe 750 and in cooperation with the above-mentioned content that the center line of the valve core 730 is in an acute angle state with the vertical direction, the entire discharge valve assembly 60 is in an inclined installation state. In one setting method, the valve core 730 is inserted into the discharge channel 761 at an angle perpendicular to the center line of the discharge channel 761. Through the inclined installation design of the valve core 730, the discharge pipe 750 can be well docked with the discharge port 511, and the discharge pipe 750 is inclined relative to the vertical, thus facilitating slurry discharge. There is no need to set an additional inclined pipe to promote the smooth discharge of the slurry. It can be seen that the "tilted discharge valve" is provided on the mixing cup device 20, which can shorten the size of the discharge pipe 750, thereby reducing the overall volume of the discharge valve assembly 60, and further reducing the overall volume of the mixing cup device 20. And because the discharge pipe 750 can be made into a straight pipe and the length of the discharge pipe 750 can be shortened, the liquid in the mixing cup 410 can be discharged smoothly, not easily blocked or remaining. The discharge pipe 750 is relatively clean and easy to clean.

[0082] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
