[0066] Steam-heated food processors are intelligent cooking devices that use high-temperature steam as their core heat source. Compared to traditional cooking methods, steam heating eliminates the need for oil, avoiding the generation of fumes and harmful substances, while preserving the nutritional components of ingredients to the greatest extent. With its healthy and efficient characteristics, it is gradually becoming an innovative tool in modern kitchens.

[0067] The technology is based on a steam circulation system. A water pump draws water from the tank into a heating element to generate steam, which is then directed into the blending cup to heat the food inside. A crucial aspect is preventing backflow and leakage of the food while allowing steam to enter the blending cup. Current technologies incorporate a steam inlet channel at the blade location, sealed with silicone. Steam pressure forces the silicone open, but this method is susceptible to seal failure due to silicone aging, ultimately leading to backflow and leakage.

[0068] To address the above issues, this application proposes a valve body device, a blending cup, and a food processor. The food processor includes a fluid supply device and a blending cup. The valve body device is applied to the food processor and is used to deliver the fluid supplied by the fluid supply device into the blending cup. The valve body device has a one-way flow sealing structure at both its inlet and outlet. Even if fluid or residue in the blending cup flows back through the one-way flow sealing structure at the outlet due to gravity or pressure, it will be blocked by the one-way flow sealing structure at the inlet. This achieves double leak-proof and backflow-proof protection for the fluid in the blending cup, ensuring the reliability of the overall backflow and leakage prevention effect of the food processor and solving the problem of easy backflow and leakage in existing blending cups.

[0069] Specifically, food processors include, but are not limited to, soymilk makers, blenders, high-speed blenders, and grinders. Food processing equipment that requires the supply of fluids such as water or steam can use this valve device to effectively prevent fluid backflow and leakage within the equipment while ensuring fluid supply.

[0070] Please see Figure 1 and Figure 2 In this embodiment, the food processor 10 includes a base 110, a water tank 120, a fluid supply device 130, and a food processor cup 20. The water tank 120 and the fluid supply device 130 are both located on the base 110, with the outlet of the water tank 120 connected to the inlet of the fluid supply device 130. The food processor cup 20 is located on the base 110 and includes a cup body 210 and a valve body device 30. The valve body device 30 includes a valve housing 310, a first valve core assembly 320, and a second valve core assembly 330. The valve housing 310 has a fluid channel 311, and an inlet 3111 and an outlet 3112 communicating with the fluid channel 311. The inlet 3111 communicates with the fluid supply device 130, and the outlet 3112 communicates with the food processor cup 20. The cup 20 is connected; the first valve core assembly 320 is disposed on the valve housing 310 and configured to unidirectionally open or block the connection between the fluid channel 311 and the outlet 3112 in the outflow direction from the fluid channel 311 via the outlet 3112; the second valve core assembly 330 is disposed on the valve housing 310 and configured to unidirectionally open or block the connection between the outlet 3112 and the fluid channel 311 in the inflow direction from the inlet 3111 into the fluid channel 311; the cup body 210 has a cooking chamber 211, and the end of the valve housing 310 with the outlet 3112 is placed in the cooking chamber 211.

[0071] By placing one end of the valve housing 310 with the outlet 3112 inside the cooking chamber 211, and connecting the inlet 3111 of the valve housing 310 to the fluid supply device 130, in the working state, the first valve core assembly 320 unidirectionally connects the fluid channel 311 and the outlet 3112 in the outflow direction from the fluid channel 311 via the outlet 3112, and the second valve core assembly 330 unidirectionally connects the outlet 3112 and the fluid channel 311 in the inflow direction from the inlet 3111 into the fluid channel 311; the fluid supply device 130 can transport water in the water tank 120 to the cooking chamber 211 through the valve housing 310. In the free state, that is, when the fluid supply device 130 stops supplying fluid, the first valve core assembly 320 blocks the connection between the fluid channel 311 and the outlet 3112, and the second valve core assembly 330 blocks the connection between the outlet 3112 and the fluid channel 311. The blocking of the first valve core assembly 320 effectively prevents liquid or residue in the blending cup 20 from flowing back into the fluid channel 311 through the outlet 3112 due to gravity or pressure. Even if the blocking of the first valve core assembly 320 is not timely, causing liquid or residue in the blending cup 20 to flow back into the fluid channel 311 from the outlet 3112, the blocking of the second valve core assembly 330 can also effectively prevent liquid or residue in the fluid channel 311 from leaking out through the inlet 3111. The first valve core assembly 320 and the second valve core assembly 330 form a double leak-proof and backflow-proof structure, achieving a long-term and effective seal at the fluid supply point of the food processor 10.

[0072] Please see Figure 3 In one embodiment, specifically, the fluid supply device 130 includes a flow meter 131, an electromagnetic pump 132, a safety valve 133, a boiler 134, a pressure relief valve (not shown), and a solenoid valve 135 connected in sequence. The above devices can be connected via water pipes, and the outlet of the water tank 120 and the flow meter 131, as well as the solenoid valve 135 and the inlet 3111 of the valve housing 310, are also connected via water pipes. Optionally, the water pipe is a silicone tube, which is heat-resistant and suitable for transmitting high-temperature water or steam heated by the boiler 134. It does not deform or release odors at high temperatures, and also has a certain degree of flexibility, suitable for the bending arrangement of the water pipes when connecting the above devices.

[0073] Understandably, the electromagnetic pump 132, as a power source for fluid transport, generates pressure through electromagnetic drive during operation, delivering water from the outlet of the water tank 120 to downstream devices such as the flow meter 131. The flow meter 131 monitors the fluid flow data in real time to ensure the required ratio of ingredients and water in the blending cup 20. The safety valve 133 automatically opens to release pressure when the pressure in the boiler 134 or pipeline exceeds the rated threshold, preventing equipment damage or explosion due to overpressure. The boiler 134 is used to heat the fluid, providing high-temperature fluid for cooking (such as making soy milk or steaming food) or cleaning (high-temperature steam sterilization). The pressure relief valve can actively regulate the pressure in the pipeline by releasing instantaneous high-pressure fluctuations during fluid flow. The electromagnetic valve 135 can control the flow of fluid, quickly opening or closing the flow channel through an electrical signal to achieve precise start and stop during fluid transport. The boiler 134 can also be replaced with an instant heater, directly heating the flowing fluid through electric heating elements such as quartz tubes, or it can be replaced with an electromagnetic induction heating device or a ceramic heater to heat the fluid.

[0074] It should be noted that the boiler 134 can heat the flowing water into steam, which is then used to heat the ingredients in the blender cup 20. Alternatively, it can heat the flowing water into hot water, which is then used to heat the ingredients in the blender cup 20. The boiler 134 can also be shut off, so that the fluid supply device 130 only serves to deliver water from the water tank 120 to the blender cup 20. Similarly, the boiler 134 can be replaced with a compressor refrigeration unit. The evaporator in the compressor refrigeration unit can absorb heat from the fluid to achieve cooling, providing low-temperature cold water to the blender, ultimately enabling the preparation of cold drinks.

[0075] Please see Figures 4 to 6 In one embodiment, the blending cup 20 proposed in this application includes a cup body 210 and a valve body device 30. The valve body device 30 includes a valve housing 310, a first valve core assembly 320, and a second valve core assembly 330. The valve housing 310 is provided with a fluid channel 311, and an inlet 3111 and an outlet 3112 communicating with the fluid channel 311. The inlet 3111 is used to communicate with the fluid supply device 130, and the outlet 3112 is used to communicate with the blending cup 20. The first valve core assembly 320 is disposed in the valve housing 310 and configured to supply fluid from the fluid channel 3111. 11. The flow direction of the outlet 3112 allows for unidirectional opening or blocking of the connection between the fluid channel 311 and the outlet 3112; the second valve core assembly 330 is disposed on the valve housing 310 and configured to unidirectionally open or block the connection between the inlet 3111 and the fluid channel 311 in the flow direction from the inlet 3111 into the fluid channel 311; the cup body 210 has a cooking chamber 211, and one end of the valve housing 310 with the outlet 3112 is placed in the cooking chamber 211, and the outlet 3112 connects the fluid channel 311 and the cooking chamber 211.

[0076] Specifically, the cup body 210 includes a cup body 212, a cup bottom cover 213, and a blade assembly 214. The cup bottom cover 213 is connected to the bottom of the cup body 212, and the blade assembly 214 is disposed on the cup bottom cover 213 and forms a cooking cavity 211 with the cup body 212. The cup bottom cover 213 is provided with a mounting groove 2131, and the blade assembly 214 is provided with a mounting port 2141a. One end of the valve housing 310 with an outlet 3112 extends into the cooking cavity 211 through the mounting port 2141a, and the other end of the valve housing 310 with an inlet 3111 is disposed in the mounting groove 2131. The bottom wall of the mounting groove 2131 is provided with a communication port 2132 aligned with the inlet 3111.

[0077] By providing a mounting groove 2131 on the cup bottom cover 213 and a mounting port 2141a on the blade assembly 214, the valve housing 310 is installed such that one end passes through the mounting port 2141a and the other end is inserted into the mounting groove 2131, thus achieving a fixed installation of the valve housing 310 within the blending cup 20. By providing a communication port 2132 aligned with the inlet 3111 on the bottom wall of the mounting groove 2131, when the outlet of the fluid supply device 130 communicates with the inlet 3111 of the valve housing 310, the communicating component can pass through the communication port 2132 to communicate with the inlet 3111 of the valve housing 310.

[0078] It should be noted that the blade assembly 214 includes a blade 2141, a blade shaft 2142, and a blade body 2143. The blade 2141 is sealed to the bottom of the cup body 212, serving as a bottom wall to form a cooking cavity 211. The blade shaft 2142 passes through the blade 2141 and is rotatably connected to it. The blade body 2143 is mounted on the blade shaft 2142 and placed in the cooking cavity 211. The bottom of the cup lid 213 is provided with a groove. The end of the blade shaft 2142 away from the blade body 2143 passes through the cup lid 213 and extends into the groove. The base 110 of the food processor 10 is provided with a clutch 160 and a motor 150 that drives the clutch 160. When the food processor cup 20 is placed on the base 110 and engaged with the base 110, the clutch 160 is inserted into the groove, so that the blade shaft 2142 is driven to connect with the clutch 160. Finally, the motor 150 drives the blade body 2143 to rotate, so as to achieve the stirring, cutting or grinding of food in the food processing chamber 211.

[0079] Optionally, the blending cup 20 is also equipped with a heating device. This heating device can be positioned below the blade 2141, indirectly heating the fluid or food within the blending chamber 211 by heating the blade 2141; alternatively, it can be positioned inside the blending chamber 211, directly heating the fluid or food within the blending chamber 211. Specifically, the heating device can be a high-power electric heating element such as a quartz tube or stainless steel heating tube, or it can be an electromagnetic induction heating device including a metal pipe and an electromagnetic coil, or a ceramic heater, etc.

[0080] Please see Figure 2 and Figure 7 In one embodiment, the valve body device 30 proposed in this application includes a valve housing 310, a first valve core assembly 320, and a second valve core assembly 330. The valve housing 310 is provided with a fluid channel 311 and an inlet 3111 and an outlet 3112 communicating with the fluid channel 311. The inlet 3111 is used to communicate with the fluid supply device 130, and the outlet 3112 is used to communicate with the food processor 20. The first valve core assembly 320 is disposed on the valve housing 310 and configured to unidirectionally conduct or block the communication between the fluid channel 311 and the outlet 3112 in the outflow direction from the fluid channel 311 via the outlet 3112. The second valve core assembly 330 is disposed on the valve housing 310 and configured to unidirectionally conduct or block the communication between the inlet 3111 and the fluid channel 311 in the inflow direction from the inlet 3111 into the fluid channel 311.

[0081] Specifically, the valve housing 310 includes a tube body 312 and a cap body 313. The cap body 313 is connected to one end of the tube body 312 and cooperates with the tube body 312 to define a fluid passage 311. An outlet 3112 is provided on the cap body 313. The first valve core assembly 320 is assembled at one end of the tube body 312 and is partially located inside the cap body 313. The second valve core assembly 330 is assembled at the other end of the tube body 312.

[0082] The cap 313 and the tube 312 cooperate to define a fluid channel 311. The first valve core assembly 320 can be first installed on the tube 312, and then the cap 313 and the tube 312 can be connected to achieve the installation of the first valve core assembly 320 within the fluid channel 311. Specifically, the cap 313 can be connected to the tube 312 by means including but not limited to adhesive bonding or screw connection.

[0083] Please see Figure 2 and Figure 8 In one embodiment, a first flange 3121 is provided on the outer periphery of one end of the tube body 312, and a insertion groove 3122 is provided on the first flange 3121; a second flange 3131 is provided on the outer periphery of one end of the cap body 313, and a insertion post 3132 is provided on the second flange 3131; the insertion post 3132 is inserted into the insertion groove 3122, and the end face of the first flange 3121 abuts against the end face of the second flange 3131. The connection between the cap body 313 and the tube body 312 can be achieved by the interference fit between the insertion groove 3122 and the insertion post 3132, or by inserting bolts or screws into the insertion groove 3122 and connecting them to the insertion post 3132, thereby achieving the connection between the cap body 313 and the tube body 312. After the cap body 313 and the tube body 312 are connected, the end face of the first flange 3121 abuts against the end face of the second flange 3131. Optionally, the end face of the first flange 3121 and the end face of the second flange 3131 are tightly fitted to achieve a sealed connection between the cap body 313 and the tube body 312.

[0084] Optionally, the first valve core assembly 320 includes a first valve core 3221 for controlling the opening and closing of the fluid channel 311 and the outlet 3112, and the second valve core assembly 330 includes a second valve core 3321 for controlling the opening and closing of the inlet 3111 and the fluid channel 311. The first valve core 3221 and the second valve core 3321 are spaced apart. In operation, the first valve core 3221 can move under the pressure impact of the fluid between the second valve core 3321 and the first valve core 3221 to achieve the opening of the outlet 3112 and the fluid channel 311. That is, the second valve core 3321 first releases the blocking effect on the fluid channel 311, so that after the fluid enters the part of the fluid channel 311 located between the second valve core 3321 and the first valve core 3221, the fluid can continue to act on the first valve core 3221, thereby achieving the opening of the outlet 3112 and the fluid channel 311. It is understandable that during the process of the second valve core 3321 and the first valve core 3221 successively releasing the blocking effect, the first valve core 3221 and the second valve core 3321 do not interfere with each other. Accordingly, the first valve core 3221 and the second valve core 3321 can independently re-block the fluid channel 311. This ensures that when the blocking of one of the first valve core 3221 and the second valve core 3321 fails, the state of the other is not affected, and it can still re-block the fluid channel 311, improving the overall sealing stability of the valve body device 30. Specifically, the movement of the first valve core 3221 under the pressure impact of the fluid can be manifested as movement or rotation, and the blocking effect on the fluid channel 311 and the outlet 3112 is released by the movement or rotation action.

[0085] Please see Figure 2 , Figure 7 and Figure 8 In one embodiment, the first valve core assembly 320 includes a first seal 321 and a first elastic valve core 322; the first seal 321 is provided with a first flow channel 3211, which connects the outlet 3112 and the fluid channel 311; the first elastic valve core 322, in its natural state, has one end connected to or abutting the cap 313, and the other end elastically pressing against the first seal 321 to block the first flow channel 3211; in the working state, the first elastic valve core 322 can be elastically compressed towards the cap 313 and open the first flow channel 3211 under the drive of the fluid.

[0086] It is understood that the working state is defined as the state in which the fluid supply device 130 supplies fluid to the cooking chamber 211 through the valve body device 30, and the natural state is defined as the state in which the fluid supply device 130 stops supplying fluid to the cooking chamber 211. In the working state, the fluid supply device 130 supplies fluid to the cooking chamber 211 through the valve body device 30. Under the impact of the flowing fluid, the first elastic valve core 322 is elastically compressed and undergoes elastic deformation. The end of the first elastic valve core 322 that presses against the first sealing member 321 moves toward the cap body 313, releasing the blockage of the first guiding flow channel 3211 and realizing the connection between the first guiding flow channel 3211 and the outlet 3112. In its natural state, the fluid supply device 130 stops supplying fluid, the force exerted by the fluid on the first elastic valve core 322 disappears, and the first elastic valve core 322 tends to return to its initial state under the action of elastic force. The end of the first elastic valve core 322 away from the cap 313 moves toward the first seal 321 and presses against the first seal 321, thereby blocking the first guiding flow channel 3211. At this time, under the obstruction of the first elastic valve core 322, the fluid or food in the cooking chamber 211 cannot flow back into the fluid channel 311 through the first guiding flow channel 3211, and the first elastic valve core 322 plays a sealing and anti-backflow role. The first elastic valve core 322 can elastically press against one end of the first sealing member 321 to cover the opening of the first flow channel 3211 at that end, thereby blocking the first flow channel 3211; the first elastic valve core 322 can also extend into the first flow channel 3211, and through the sealing fit between the outer peripheral wall of the first elastic valve core 322 and the inner wall of the first flow channel 3211, the first flow channel 3211 can be blocked.

[0087] Optionally, the second valve core assembly 330 includes a second seal 331 and a second elastic valve core 332; the second seal 331 is located at the inlet 3111 and has a second flow channel 3311, which connects the inlet 3111 and the fluid channel 311; the second elastic valve core 332 is located in the fluid channel 311, and a limiting member 3124 is provided on the inner wall of the fluid channel 311; in the natural state, one end of the second elastic valve core 332 is connected to or abuts against the limiting member 3124, and the other end elastically presses against the second seal 331 to block the second flow channel 3311; in the working state, the second elastic valve core 332 can be elastically compressed towards the limiting member 3124 and open the second flow channel 3311 under the drive of the fluid. Specifically, the limiting member 3124 can be an annular protrusion on the inner wall of the tube 312 and integrally formed with the tube 312, or it can be an independent component fixedly connected to the inner wall of the tube 312.

[0088] In operation, the fluid supply device 130 delivers fluid to the cooking chamber 211 through the valve body device 30. Under the impact of the flowing fluid, the second elastic valve core 332 is elastically compressed and undergoes elastic deformation. The end of the second elastic valve core 332 that presses against the second seal 331 moves toward the limiting member 3124, releasing the blockage of the second guiding flow channel 3311 and realizing the connection between the second guiding flow channel 3311 and the fluid channel 311. In its natural state, the fluid supply device 130 stops supplying fluid, the force exerted by the fluid on the second elastic valve core 332 disappears, and the second elastic valve core 332 tends to return to its initial state under the action of elastic force. The end of the second elastic valve core 332 away from the limiting member 3124 moves toward the second sealing member 331 and presses against the second sealing member 331, thereby blocking the second guiding channel 3311. At this time, under the obstruction of the second elastic valve core 332, the fluid in the fluid channel 311 cannot flow back through the second guiding channel 3311, and therefore cannot leak back through the inlet 3111. At the same time, during the process of the first elastic valve core 322 re-sealing the first guiding channel 3211, a small amount of fluid or residue in the cooking chamber 211 may flow back through the first guiding channel 3211 and enter the fluid channel 311 between the first sealing member 321 and the second elastic valve core 332. At this point, blocked by the second elastic valve core 332, the fluid or residue cannot continue to flow back through the second guiding channel 3311, and therefore cannot leak back through the inlet 3111. The first elastic valve core 322 and the second elastic valve core 332 provide a double sealing and anti-backflow function. The second elastic valve core 332 can elastically press against one end of the second sealing member 331 to cover the opening of the second guiding channel 3311 at that end, thereby blocking the second guiding channel 3311; the second elastic valve core 332 can also extend into the second guiding channel 3311, and through the sealing fit between the outer peripheral wall of the second elastic valve core 332 and the inner wall of the second guiding channel 3311, the second guiding channel 3311 is blocked.

[0089] Considering that when the fluid drives the second elastic valve core 332 to elastically compress towards the limiting member 3124 to open the second guiding flow channel 3311, the instantaneous pressure generated by the fluid impacting the second elastic valve core 332 is relatively large, which requires a high connection sealing strength at the inlet 3111 of the valve body 310, and is prone to causing the sealing failure at the connection between the fluid supply device 130 and the inlet 3111 of the valve body 310.

[0090] Please see Figure 1 and Figure 7In one embodiment, the base 110 is further provided with a connecting pipe 140, and the outlet of the fluid supply device 130 is connected to the connecting pipe 140. When the cooking cup 20 is engaged with the base 110, the connecting pipe 140 extends into the fluid channel 311 through the inlet 3111 of the valve housing 310. In the natural state, one end of the second elastic valve core 332 of the second valve core assembly 330 is connected to or abuts against the limiting member 3124 on the inner wall of the fluid channel 311, and the other end elastically presses against the connecting pipe 140 to block the outlet of the connecting pipe 140. In the working state, the second elastic valve core 332 can be elastically compressed towards the limiting member 3124 under the drive of the fluid and open the outlet of the connecting pipe 140. The second elastic valve core 332 is pushed open by the connecting pipe 140, moving it away from the inlet 3111 of the valve housing 310. In operation, the fluid flowing out of the connecting pipe 140 impacts the second elastic valve core 332. The fluid flowing back towards the inlet 3111 of the valve housing 310 due to the obstruction of the second elastic valve core 332 is momentarily dissipated during the flow, reducing or even preventing the possibility of fluid leakage between the connecting pipe 140 and the second seal 331. In its natural state, one end of the second elastic valve core 332 of the second valve core assembly 330 abuts against the limiting member 3124 on the inner wall of the fluid channel 311, and the other end elastically presses against the connecting pipe 140 to block the outlet of the connecting pipe 140. This does not affect the double-sealing anti-backflow effect of the first valve core assembly 320 and the second valve core assembly 330.

[0091] Understandably, after the second elastic valve core 332 is pushed open by the connecting pipe 140 and moved away from the inlet 3111 of the valve body 310, the fluid passage 311 is connected to the external fluid supply device 130 through the connecting pipe 140. Fluid flows into the fluid passage 311 through the outlet of the connecting pipe 140. Taking the valve body device 30 as an example with a vertical arrangement, the height of the outlet of the connecting pipe 140 is obviously higher than the height of the inlet 3111 of the valve body, and the height of the connecting pipe 140 at its outlet can be higher than that of the second seal. At height 331, even if a small amount of fluid or residue in the cooking chamber 211 flows into the bottom of the fluid channel 311 inside the valve housing 310 after passing through the first elastic valve core 322 and the second elastic valve core 332, due to the height difference between the outlet of the connecting pipe 140 and the second seal 331, this part of the fluid or residue accumulates on the periphery of the connecting pipe 140 and cannot flow back into the external fluid supply device 130 through the outlet of the connecting pipe 140. That is, the insertion design of the connecting pipe 140 can also play a further role in preventing backflow.

[0092] Please see Figure 2 and Figure 8In one embodiment, the cap 313 is sleeved on the outer periphery of the first sealing member 321, and at least a portion of the outer peripheral wall of the first elastic valve core 322 abuts against the inner wall of the first guiding channel 3211; wherein, the outlet 3112 is provided on the peripheral wall of the cap 313, and the inner wall of the first guiding channel 3211 is provided with a guiding port 3212 connecting the outlet 3112 and the first guiding channel 3211; in the natural state, the first elastic valve core 322 can block the guiding port 3212; in the working state, the first elastic valve core 322 can be elastically compressed toward the cap 313 and open the guiding port 3212 under the drive of the fluid.

[0093] By setting the outlet 3112 on the peripheral wall of the cap 313 and setting the outer peripheral wall of the first elastic valve core 322 to abut against the inner wall of the first guiding channel 3211, the first guiding channel 3211 needs to pass through the guiding port 3212 on the inner wall of the first guiding channel 3211 to achieve communication with the outlet 3112. In its natural state, in addition to blocking the first guiding channel 3211 by the end face extending into one end of the first guiding channel 3211, the first elastic valve core 322 also blocks the guiding port 3212 by the side wall extending into one end of the first guiding channel 3211. That is, the first elastic valve core 322 achieves double blocking of the guiding port 3212 and the first guiding channel 3211, further enhancing the sealing and backflow prevention effect of the first elastic valve core 322. In operation, when the first elastic valve core 322 is elastically compressed towards the cap 313, the end of the first elastic valve core 322 away from the cap 313 needs to move to the position where the opening of the guide port 3212 is opened in order to achieve communication between the first guide channel 3211 and the outlet 3112. Of course, the end of the cap 313 away from the first seal 321 also has a portion that is not in contact with the first seal 321. The outlet 3112 can also be directly located on this portion of the cap 313 that is not in contact with the first seal 321. In operation, when the first elastic valve core 322 is elastically compressed towards the cap 313, the end of the first elastic valve core 322 away from the cap 313 needs to move to the position where the opening of the first guide channel 3211 on the end of the first seal 321 is opened in order to achieve communication between the first guide channel 3211 and the outlet 3112.

[0094] Understandably, when the valve body device 30 is installed at the bottom of the blending cup 20, the first elastic valve core 322 and the second elastic valve core 332 are arranged vertically. In the working state, the first elastic valve core 322 and the second valve core 3321 undergo elastic deformation upward under the action of the fluid. When switched to the natural state, the first elastic valve core 322 and the second elastic valve core 332 can more quickly block the first guide channel 3211 and the second guide channel 3311 under the action of elastic force and gravity, thereby improving the anti-backflow effect.

[0095] Specifically, the outer periphery of the tube body 312 of the valve housing 310 is provided with a mounting bracket 3125, which is connected to the bottom surface of the cutter disc assembly 214. The cap 313 of the valve housing 310 extends at least partially into the cooking chamber 211 through the mounting port 2141a on the cutter disc assembly 214, and the portion of the cap 313 extending into the cooking chamber 211 is provided with an outlet 3112. The connection method between the mounting bracket 3125 and the cutter disc assembly 214 includes, but is not limited to, bolt connection or snap-fit ​​connection.

[0096] By placing the outlet 3112 on the side wall of the cap 313, the likelihood of fluid or residue in the cooking chamber 211 flowing back through the outlet 3112 due to gravity is reduced compared to placing the outlet 3112 on the top of the cap 313. Alternatively, the valve device 30 can also be placed on the side wall of the cooking cup 20 body 210. In this case, the installation height of the valve device 30 on the cooking cup 20 can be increased to reduce the likelihood of fluid or residue in the cooking chamber 211 flowing back through the outlet 3112 due to pressure. Typically, the cooking cup 20 also includes a lid 215 and a handle 216 on the cup body 210; correspondingly, the valve device 30 can also be placed on the lid 215 or the handle 216.

[0097] Optionally, a sealing ring 340 is fitted around the outer periphery of the cap 313. The sealing ring 340 is used to seal the connection between the cooking cup 20 and the cap 313. Specifically, the cap 313 extends into the cooking chamber 211 through the mounting port 2141a on the blade assembly 214. The sealing ring 340 is fitted around the outer periphery of the cap 313 and is sealed to the inner wall of the mounting port 2141a, sealing the installation gap between the cap 313 and the inner wall of the mounting port 2141a, and preventing fluid or residue in the cooking chamber 211 from leaking through the gap between the cap 313 and the inner wall of the mounting port 2141a.

[0098] Please continue reading. Figure 2 and Figure 8 In one embodiment, the first elastic valve core 322 includes a first valve core 3221 and a first elastic member 3222; the first valve core 3221 has a limiting portion 3221a at one end away from the inlet 3111; one end of the first elastic member 3222 is connected to or abuts against the cap 313, and the other end is located at the limiting portion 3221a and is connected to or abuts against the first valve core 3221. The second elastic valve core 332 includes a second valve core 3321 and a second elastic member 3322; one end of the second elastic member 3322 is connected to or abuts against the limiting member 3124, and the other end is connected to or abuts against the second valve core 3321.

[0099] By providing a limiting part 3221a at one end of the first valve core 3221 facing the cap 313, the first elastic member 3222 can be positioned at the limiting part 3221a when it connects or abuts against the first valve core 3221. The limiting part 3221a can limit the first elastic member 3222 in the circumferential direction, preventing the first elastic member 3222 from bending during elastic compression, which would cause the first valve core 3221 to fail to reset properly. One end of the first elastic element 3222 is connected to or abuts against the cap 313. When assembling the first valve core assembly 320, the first sealing element 321, the first valve core 3221, and the first elastic element 3222 can be assembled sequentially first, and then the cap 313 is connected to the tube 312. The cap 313 presses against the first elastic element 3222, thereby enabling the first elastic element 3222 to drive the first valve core 3221 to press against the first sealing element 321, thus completing the convenient installation of the first valve core assembly 320 in the valve housing 310. Specifically, the limiting part 3221a can be set as a limiting groove, in which case the end of the first elastic element 3222 connected to or abutting against the first valve core 3221 can be placed in the limiting groove; the limiting part 3221a can also be set as a limiting post, in which case the end of the first elastic element 3222 connected to or abutting against the first valve core 3221 can be wrapped around the limiting post.

[0100] Specifically, the first elastic element 3222 includes, but is not limited to, a compression spring, a rubber spring, or a thermoplastic elastomer. The first elastic valve core 322 is configured to include a first valve core 3221, and the second elastic valve core 332 is configured to include a second valve core 3321. The first valve core 3221 and the second valve core 3321 are made of materials such as silicone rubber or polyurethane elastomer, which possess both elasticity and sealing capabilities. This allows the first valve core 3221 and the second valve core 3321 to not only block the first and second flow channels 3211 and 3311 respectively, but also to achieve the opening of the first and second flow channels 3211 and 3311 through their own elastic deformation.

[0101] Optionally, in one embodiment, in the flow direction of the fluid flowing into the first guiding channel 3211 through the fluid channel 311, the first guiding channel 3211 has a gradually expanding section 3213 with a gradually increasing inner diameter, the gradually expanding section 3213 has a concave arc inner wall, and the end of the first valve core 3221 facing away from the first elastic member 3222 has a concave arc end face; in the natural state, the concave arc end face of the first valve core 3221 abuts against the concave arc inner wall of the gradually expanding section 3213.

[0102] Understandably, in its natural state without external force, the first valve core 3221, under the elastic force of the first elastic element 3222, can achieve a tight fit between its concave arc end face and the concave arc inner wall of the expanding section 3213, thereby sealing the first flow channel 3211. In operation, the first valve core 3221 moves towards the cap 313 under the influence of the fluid, compressing the first elastic element 3222, causing its concave arc end face to separate from the concave arc inner wall of the expanding section 3213, thus achieving connection between the first flow channel 3211 and the outlet 3112. By setting the sealing surfaces of the first valve core 3221 and the first sealing element 321 as concave arc surfaces, even when the first valve core 3221 oscillates radially, it can maintain the contact between its concave arc end face and the concave arc inner wall of the expanding section 3213, preventing gaps from forming due to oscillation. This achieves a stable and effective seal between the first valve core 3221 and the first sealing element 321.

[0103] Correspondingly, in the flow direction of the fluid flowing into the fluid channel 311 through the second guiding channel 3311, one end of the second guiding channel 3311 is provided with a concave arc inner wall, and the end of the second valve core 3321 facing away from the second elastic member 3322 has a concave arc end face; in the natural state, the concave arc end face of the second valve core 3321 abuts against the concave arc inner wall of the second guiding channel 3311.

[0104] Specifically, the end of the first valve core 3221 facing away from the first elastic element 3222 can be configured as a sphere or an ellipsoid, and the first valve core 3221 as a whole can be configured as a cylinder with a U-shaped axial cross-section; the end of the second valve core 3321 facing away from the second elastic element 3322 can be configured as a sphere or an ellipsoid, and the second valve core 3321 as a whole can be configured as a sphere or an ellipsoid. The first valve core 3221 and the second valve core 3321 can be made of metal, including but not limited to stainless steel, carbon steel, or copper alloy.

[0105] Please see Figure 2In one embodiment, the outer periphery of the first sealing member 321 is provided with a connecting protrusion 3214. The portion of the first sealing member 321 located on one side of the connecting protrusion 3214 is inserted into the cap body 313, and the portion of the first sealing member 321 located on the other side of the connecting protrusion 3214 is inserted into the tube body 312. The inner wall of the cap body 313 is provided with a first stepped surface 3133, and the connecting protrusion 3214 is sandwiched between the first stepped surface 3133 and the end face of the tube body 312. By providing a connecting protrusion 3214 on the outer periphery of the first seal 321, after the first seal 321 is assembled, the connecting protrusion 3214 is sandwiched between the first step surface 3133 of the cap 313 and the end face of the tube 312, thereby achieving the positioning and installation of the first seal 321 within the valve housing 310. The two end faces of the connecting protrusion 3214 can be tightly fitted with the first step surface 3133 and the end face of the tube 312, respectively, so as to achieve a sealing connection between itself and the valve housing 310 while avoiding affecting the sealing performance of the connection between the cap 313 and the tube 312.

[0106] Furthermore, in one embodiment, the inner wall of the cap 313 is provided with a second stepped surface 3134, the inner wall of the tube 312 is provided with a third stepped surface 3123, one end of the first sealing member 321 abuts against the second stepped surface 3134, and the other end abuts against the third stepped surface 3123. By providing a second stepped surface 3134 on the inner wall of the cap 313, one end of the first sealing member 321 is inserted into the cap 313 and abuts against the second stepped surface 3134, thereby improving the sealing performance between the first sealing member 321 and the inner wall of the cap 313. By providing a third stepped surface 3123 on the inner wall of the tube 312, the other end of the first sealing member 321 is inserted into the tube 312 and abuts against the third stepped surface 3123, thereby improving the sealing performance between the first sealing member 321 and the inner wall of the tube 312. In other words, the sealing performance between the first sealing member 321 and the inner wall of the fluid channel 311 is improved, preventing fluids on both sides of the first sealing member 321 from flowing through the gap between the side wall of the first sealing member 321 and the inner wall of the fluid channel 311. Optionally, the outer periphery of the first seal 321 is also provided with a plurality of sealing protrusions. The plurality of sealing protrusions are spaced apart in the axial direction of the first seal 321. The plurality of sealing protrusions abut against the inner walls of the cap 313 and the tube 312 respectively, so as to improve the sealing performance between the first seal 321 and the cap 313 and the tube 312.
