Description

Technical Field

[0001] The present invention relates to the technical field related to food processor accessories, and in particular to an elastic pneumatic material dropping mechanism and a food processor. Background Art

[0002] In modern kitchen equipment, food processors, as a multifunctional kitchen appliance, have gradually become an indispensable cooking tool in households and the catering industry due to their convenience and efficiency. Food processors put various ingredients into the cooking cup and process the ingredients using the built-in cutting device to produce a variety of foods. Among them, the reservation function provides great convenience for users, allowing users to set the preparation time in advance, so that the food processor automatically starts working at the specified time without manual waiting.

[0003] However, in actual use, the cooking machine's reservation function has also exposed some limitations. Especially for ingredients that need to be soaked, such as beans, long-term soaking may cause the ingredients to deteriorate, thus affecting the quality and taste of the final food. For example, in the process of making soy milk by appointment, if the beans are soaked in the cooking cup for a long time, they may deteriorate due to factors such as water quality and temperature, resulting in the scheduled soy milk being unable to be drunk normally. This problem not only limits the scope of use of the cooking machine's reservation function, but also brings inconvenience to users.

[0004] In order to solve the above problems, some attempts have been made in the prior art, such as the solution described in patent 202320387355.5. However, this solution still has certain risks in practical application, such as the problem of uneven feeding after the beans are soaked and washed, which may affect the normal operation of the food processor and the food production effect. Summary of the invention

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides an elastic pneumatic material dropping mechanism and a food processor, which can solve the problem of soaking beans in water in advance.

[0006] The technical solution adopted by the present invention to solve the problem is:

[0007] A pneumatic elastic blanking mechanism comprises: a silo, a discharge port is provided at the bottom of the silo; a cup cover, a feed port is provided at the top of the cup cover, the discharge port is communicated with the feed port, and the feed port is used to provide air pressure for the discharge port; a material cover, the material cover is assembled on the top of the silo, and the material cover is provided with a first sliding channel facing the discharge port; a sliding component, the sliding component is slidably arranged in the first sliding channel, and there is a sealed state and an open state between the sliding component and the discharge port, and an elastic member for providing an upward thrust to the sliding component is also arranged in the first sliding channel; a locking member, the locking member is assembled on the material cover or the silo, and the locking member is provided with an elastically contractible trigger member; when the sliding component and the discharge port are in a sealed state, the trigger member is engaged with the sliding component, and when the air pressure increases to cause the trigger member to disengage from the sliding component, the elastic member drives the sliding component to rise, and the sliding component and the discharge port are in an open state.

[0008] By adopting the above solution, the sliding component can be driven by air pressure to move, so that the material bin can be unloaded, and the function of automatic unloading at a specified time can be realized. This means that the bean ingredients do not need to be soaked in the cooking cup for a long time, thus avoiding the problem of food deterioration. When the solution under the cup cover is heated, the air pressure in the cup cover increases. When the air pressure reaches a large enough level, it can overcome the friction between the sliding component and the discharge port, and the friction between the trigger and the sliding component, so that the sliding component moves upward to unload the material.

[0009] Furthermore, the sliding assembly includes a handle and a push rod connected to each other, the first sliding channel has a first lip extending in the direction of the discharge port, the first sliding channel has a second lip extending in the direction away from the discharge port, the second lip is bent twice continuously into the first sliding channel to form a second sliding channel, the handle is slidably disposed in the second sliding channel, and the push rod is slidably disposed in the first sliding channel.

[0010] By adopting the above scheme, the first sliding channel provides a sliding track for the push rod, ensuring that the push rod can move stably therein, and the first lip is used to limit the lateral movement of the push rod during the sliding process, thereby enhancing the stability and accuracy of the sliding; the second lip increases the length of the sliding path of the push rod, thereby providing greater resistance or buffering, so that the handle can move more smoothly under the action of air pressure; the second sliding channel provides a sliding track for the handle, ensuring that the handle can move stably therein.

[0011] Further, the handle includes: a first cylindrical section, one end of the first cylindrical section is provided with an abutting edge, the abutting edge is used to abut with one end of the second sliding channel, the other end of the first cylindrical section is slidably arranged in the second sliding channel; a second cylindrical section, one end of the second cylindrical section is connected to the other end of the first cylindrical section, the other end of the second cylindrical section is connected to the push rod, and the cross-sectional area of ​​the second cylindrical section is smaller than the cross-sectional area of ​​the first cylindrical section; an annular groove, the annular groove is arranged at the other end of the first cylindrical section and is arranged along the circumferential outer side of the second cylindrical section, and the elastic member is arranged in the annular groove.

[0012] By adopting the above scheme, the abutment edge is used to abut against one end of the second sliding channel, thereby limiting the maximum displacement of the handle during the sliding process. The second cylindrical section can slide along the third abutment edge to increase its sliding stability. The elastic member can ensure that the handle will not rise or fall too quickly during the movement to cause bumps, providing a buffering effect for the handle, avoiding the generation of noise, and at the same time providing an upward reset thrust for the handle.

[0013] Furthermore, an assembly platform is provided at one end of the push rod close to the discharge port, an assembly groove is provided at one end of the assembly platform facing the second cylindrical section, and the other end of the second cylindrical section is assembled in the assembly groove.

[0014] By adopting the above solution, the other end of the second cylindrical section can be accurately assembled into the assembly groove, thereby achieving a firm connection between the handle and the push rod. This connection method is not only simple and reliable, but also easy to manufacture and install.

[0015] Furthermore, a first air groove is provided at one end of the assembly platform facing the discharge port, an air hole is provided between the first air groove and the assembly groove, a second air groove is provided at the other end of the second cylindrical section corresponding to the air hole, and the first air groove, the air hole and the second air groove are interconnected.

[0016] By adopting the above solution, it is ensured that the air pressure can be stably and efficiently transmitted to the push rod, thereby driving the push rod to complete the material discharge action. The interconnected air pressure transmission channels also help reduce leakage and loss during the air pressure transmission process, thereby improving the efficiency and accuracy of the air pressure transmission.

[0017] Furthermore, the elastic force of the elastic member is smaller than the friction force of the interference connection between the push rod and the discharge port; the elastic deformation length of the elastic member is smaller than the length of the second sliding channel; the length of the second sliding channel is smaller than the length of the first sliding channel; the elastic deformation length of the elastic member is 20mm-30mm.

[0018] By adopting the above solution, the length of the second sliding channel is less than that of the first sliding channel. This design ensures that the handle can be sufficiently restricted and supported during the sliding process, preventing it from losing stability due to being too long; the length range of the elastic member ensures that the elastic member can provide sufficient restoring force when subjected to air pressure, and will not lose stability due to excessive deformation.

[0019] Furthermore, the locking member includes: a lock frame, the lock frame is connected to the bottom end of the material cover, a third sliding channel is provided on the side of the lock frame facing the sliding assembly, and the trigger member is partially slidably disposed in the third sliding channel; a reset member, one end of the reset member abuts against the lock frame, and the other end abuts against the trigger member.

[0020] By adopting the above solution, it is ensured that the locking member can be firmly fixed on the material cover and will not loosen or fall off due to external factors. The third sliding channel provides space and guidance for the sliding of the trigger member. When the air pressure disappears or the external control force disappears, the reset member can push the trigger member back to the initial position, providing the trigger member with a force to slide toward the sliding assembly, thereby realizing the locking function.

[0021] Furthermore, a first slot is provided on the side wall of the push rod, and the first slot is engaged with the trigger member. When the trigger member is engaged with the first slot, the push rod is interference-connected with the discharge port.

[0022] By adopting the above solution, it is ensured that when the trigger member is engaged, the push rod can be stably maintained at the discharge port and will not move due to external factors.

[0023] Furthermore, a second slot is provided on the side wall of the push rod, and a sealing member is provided in the second slot.

[0024] By adopting the above solution, an interference fit between the sealing element and the push rod can be achieved, thereby improving the sealing effect.

[0025] A food processor comprises a food processor body, a food processor cup body and an elastic pneumatic material dropping mechanism mounted on the food processor cup body. A heating device is arranged in the food processor body. The pressure of the solution in the food processor cup body rises after being heated, and air pressure is provided for the material inlet to drive the sliding component to rise.

[0026] By adopting the above scheme, automatic heating can be achieved according to the food processor's own timing. After heating, the sliding component in the hopper can be opened by air pressure to automatically drop the ingredients, thus avoiding the problem of ingredients in the hopper being soaked in water and deteriorating. At the same time, after the sliding component is opened, it is raised by the elastic part, which will not cause the problem of stuck dropping of ingredients.

[0027] In summary, the elastic pneumatic material dropping mechanism and food processor provided by the present invention have the following technical effects:

[0028] 1. Through this feeding mechanism, bean ingredients do not need to be soaked in the cooking cup for a long time, thus effectively avoiding the problem of food deterioration caused by long-term soaking. This ensures the freshness of the ingredients and the quality and taste of the final food. By avoiding food deterioration, users can use the ingredients more efficiently and reduce waste caused by food deterioration;

[0029] 2. The material-feeding mechanism drives the handle and push rod to move through air pressure, realizing the function of automatic material-feeding at a specified time. This greatly improves the automation of kitchen equipment and reduces the tediousness of manual operation. The automatic material-feeding function enables the food processor to automatically start working at the time set by the user without manual waiting. This improves the efficiency of kitchen equipment and saves users valuable time;

[0030] 3. The material-dropping mechanism is connected by interference sealing between the push rod and the material outlet, and the clip connection design between the trigger and the push rod ensures that the material-dropping mechanism can maintain a stable state when material-dropping is not required. This design effectively prevents accidental material-dropping or damage to the mechanism caused by external factors, reduces friction and wear of the mechanism during movement, and thus extends the service life of the equipment;

[0031] 4. This material dropping mechanism is not only suitable for the problem of scheduled soaking of bean ingredients, but can also be applied to other scenarios that require timed material dropping. This provides users with more choices and flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] Embodiment 1 of the present invention refers to Figure 1-Figure 7As shown, an elastic pneumatic dropping mechanism and a food processor are disclosed, including a cup cover 1, a material bin 2, a material cover 3, a sliding assembly and a locking member 6. The cup cover 1 is used to cover the food processor cup body on the top of the food processor body. The food processor is preferably a soymilk maker. In other embodiments, the specific function and model are not limited. The cup cover 1 is provided with a feed inlet 11 on the top, and the material bin 2 is provided with a discharge port 21 at the bottom. The discharge port 21 is communicated with the feed inlet 11. Preferably, the material bin 2 is assembled and fixed above the cup cover 1, and the material cover 3 is assembled on the top of the material bin 2, and the material cover 3 is provided with a first sliding channel 31 facing the discharge port 21. The sliding assembly is slidably disposed in the first sliding channel 31, and there is a sealed state and an open state between the sliding assembly and the discharge port 21. The first An elastic member 44 for providing an upward thrust to the sliding assembly is also provided in the sliding channel 31; the locking member 6 is assembled on the material cover 3 or the material bin 2, and the locking member 6 is provided with an elastically contractible trigger member 63; when the sliding assembly and the discharge port 21 are in a sealed state, the trigger member 63 is engaged with the sliding assembly, and when the air pressure increases to disengage the trigger member 63 from the sliding assembly, the elastic member 44 drives the sliding assembly to rise, and the sliding assembly and the discharge port 21 are in an open state.

[0045] When in use, place the sliding component into the first sliding channel 31 from above the material cover 3, and continue to press downward along the first sliding channel 31 until the sliding component is engaged with the trigger member 63, at which time the bottom end of the sliding component is connected to the discharge port 21 by interference sealing, and the air pressure Q1 in the cup cover 1 satisfies the following formula, N1+Q1<M1+M2+G1, wherein N1 is the elastic force of the elastic member 44, M1 is the sealing friction between the sliding component and the discharge port 21, M2 is the engagement friction between the trigger member 63 and the sliding component, and G1 is the weight of the sliding component itself; when the solution under the cup cover 1 is heated, Q1 increases, and when the air pressure When Q1+N1>M1+M2+G1, the sliding assembly moves upward, at which time the sliding assembly and the trigger member 63 are directly disengaged, and the sliding assembly gradually moves away from the discharge port 21 until there is no contact, and then the elastic force of the elastic member 44 can drive the sliding assembly to rise to an open state, and the material in the silo 2 can enter the cup cover 1 from the discharge port 21 to complete the discharge, through the interference seal connection between the sliding assembly and the discharge port 21 and the card connection design of the trigger member 63 and the sliding assembly, it is ensured that the blanking mechanism can maintain a stable state when no discharge is required, and the discharge process is completely controlled by air pressure, without manual operation, thereby improving the degree of automation and production efficiency.

[0046] In order to improve the stability of the longitudinal sliding of the sliding component, it is necessary to extend the length of the first sliding channel 31. To this end, in some embodiments, a first lip 311 extends from the first sliding channel 31 in the direction of the discharge port 21, and a second lip 312 extends from the first sliding channel 31 in the direction away from the discharge port 21. The first sliding channel 31 provides a sliding track for the sliding component to ensure that the handle 4 can move stably therein. The first lip 311 is to limit the lateral movement of the sliding component during the sliding process to enhance the stability and accuracy of the sliding; the second lip 312 increases the sliding path length of the sliding component, thereby providing greater resistance or buffering, so that the sliding component can move more smoothly under the action of air pressure.

[0047] In order to facilitate filling, in some embodiments, a filling port 33 is provided at the top of the material cover 3 to avoid the first sliding channel 31. The filling port 33 is used to fill the material bin 2. In order to prevent dust from entering the filling port 33, a movable cover 34 is provided at the filling port 33. The movable cover 34 and the material cover 3 are connected by hinges, snap-fits or sliding connections, but are not limited to. In this embodiment 1, the filling port 33 is fan-shaped, and the movable cover 34 is also fan-shaped. The fan ring angles of the two fan rings do not exceed 180°. The movable cover 34 rotates with the center of the first sliding channel 31 as the axis, thereby covering or opening the filling port 33. In order to facilitate the operation of the movable cover 34, a toggle plate 35 is provided on the movable cover 34, so that the user can operate the toggle plate 35 to open the filling port 33 for filling.

[0048] Optionally, the shapes of the cup cover 1, the material bin 2, and the material cover 3 include but are not limited to square or round, as long as they can fit the food processor. The structure of the first sliding channel 31 is also not limited to a columnar or prism shape. Preferably, the first sliding channel 31 is located in the center of the material cover 3 to match the discharge port 21 located in the center of the material bin 2 and the inlet port 11 located in the center of the cup cover 1.

[0049] In this embodiment 1, the sliding assembly includes a handle 4 and a push rod 5 connected to each other, and the handle 4 and the push rod 5 are connected by, but not limited to, snap-fitting, bonding or screwing. Specifically, one end of the handle 4 passes through the first sliding channel 31 and is connected to the push rod 5, and the push rod 5 is sealed and connected to the discharge port 21, and the other end of the handle 4 is limited to the outside of the first sliding channel 31 at the end of the handle 4 away from the discharge port 21; the locking member 6 is assembled under the material cover 3, and the trigger member 63 is snap-fitted with the side wall of the push rod 5, so that the handle 4 and the top cover can be driven to move by air pressure, so that the material bin 2 can be unloaded, and the function of automatically unloading at a specified time is realized. This means that the bean ingredients do not need to be soaked in the cooking cup for a long time, thereby avoiding the problem of food deterioration. When the solution under the cup cover 1 is heated, the air pressure in the cup cover 1 increases. When the air pressure reaches a sufficiently large level, it can overcome the friction between the push rod 5 and the discharge port 21, the clamping friction between the trigger member 63 and the push rod 5, and the total weight of the push rod 5 and the handle 4, thereby pushing the push rod 5 and the handle 4 to move upward to achieve material discharge.

[0050] In this embodiment 1, the locking member 6 includes a locking frame 61, a reset member 62 and a trigger member 63. The locking frame 61 is connected to the bottom end of the material cover 3, and the connection method includes but is not limited to welding, clamping or screwing. The locking frame 61 is provided with a third sliding channel 611 on the side facing the push rod 5. The trigger member 63 is partially slid in the third sliding channel 611. The reset member 62 is assembled in the third sliding channel 611, and one end of the reset member 62 abuts against the locking frame 61, and the other end abuts against the trigger member 63, which is used to provide a force for the trigger member 63 to slide in the direction of the push rod 5, thereby ensuring that the locking member 6 can be firmly fixed on the material cover 3, and at the same time, it is necessary to ensure that the trigger member 63 will not separate from the locking frame 61. The side wall of the push rod 5 is provided with an annular first slot 52, which is engaged with the trigger member 63. After the two are engaged, they will not be easily loosened or fall off due to external shaking factors. The third sliding channel 611 provides space and guidance for the sliding of the trigger member 63. When the air pressure disappears or the external control force disappears, the reset member 62 can push the trigger member 63 back to the initial position to achieve the locking function. Preferably, the reset member 62 is a spring.

[0051] It should be noted that the number of the locking members 6 can be multiple, and what needs to be ensured is that the pressure of the temperature rise needs to be greater than the total friction force of the locking members 6 to avoid the problem of being unable to drop the material. At the same time, the second lip plate is provided with an avoidance gap corresponding to each trigger member 63.

[0052] When the trigger member 63 is engaged with the first slot 52, the push rod 5 is in interference connection with the discharge port 21, ensuring that when the trigger member 63 is engaged, the push rod 5 can be stably maintained at the discharge port 21 and will not move due to external factors. The stability of the material in the silo 2 is ensured, and there will be no accidental material falling. Preferably, the trigger member 63 is a ejector pin.

[0053] In order to improve the stability of the longitudinal sliding of the handle 4 and the push rod 5, in some embodiments, a first lip 311 extends from the first sliding channel 31 toward the discharge port 21, and a second lip 312 extends from the first sliding channel 31 away from the discharge port 21. The second lip 312 is bent twice into the first sliding channel 31 to form a second sliding channel 32, so that the handle 4 slides in the second sliding channel 32, and the push rod 5 is slidably arranged in the first sliding channel 31, ensuring that the handle 4 and the push rod 5 can move stably therein, thereby improving the overall sliding stability.

[0054] In order to limit the position of the handle 4, in some embodiments, an abutting edge 411 is provided at one end of the handle 4 away from the push rod 5, and the abutting edge 411 is used to abut against the top of the second sliding channel 32 to prevent the handle 4 from completely sliding into the second sliding channel 32. An additional fixing or limiting point is provided for the handle 4 to ensure that the handle 4 can stably stay in a certain position when the air pressure is insufficient or when material feeding is not required.

[0055] In some embodiments, the handle 4 is further improved. Specifically, the handle 4 includes a first cylindrical section 41, a second cylindrical section 42 and an annular groove 43. The cross-sectional area of ​​the second cylindrical section 42 is smaller than the cross-sectional area of ​​the first cylindrical section 41. The abutting edge 411 is arranged at one end of the first cylindrical section 41, and one end of the second cylindrical section 42 is connected to the other end of the second cylindrical section 42, and the two are coaxial. The first cylindrical section 41 can slide along the second sliding channel 32, and the second sliding channel 32 is close to the discharge port. The direction of the opening 21 is bent toward the inside of the second sliding channel 32 to form a third abutting edge 321, and the third abutting edge 321 abuts against the side of the second cylindrical segment 42 to improve the sliding stability of the second cylindrical segment 42. Therefore, the length of the third abutting edge 321 is equal to the radius difference between the first cylindrical segment 41 and the second cylindrical segment 42. The other end of the second cylindrical segment 42 passes through the center of the third abutting edge 321 and is connected to the push rod 5. The annular groove 43 is arranged at the other end of the first cylindrical segment 41 and is arranged along the circumferential outer side of the second cylindrical segment 42. The annular groove 43 extends along the surface of the second cylindrical section 42 into the first cylindrical section 41 and is used to install an elastic member 44. The elastic member 44 is preferably a spring. One end of the elastic member 44 abuts against the annular groove 43, and the other end abuts against the third abutting edge 321. Under normal conditions, the elastic force of the elastic member 44 is greater than the gravity of the handle 4 and the push rod 5, and can lift the two to put the sliding assembly in an open state. The elastic member 44 can also ensure that the handle 4 will not fall due to gravity and cause bumps, providing a buffering effect for the handle 4 and avoiding the generation of noise. At the same time, the second sliding channel 32, the third abutting edge 321 and the annular groove 43 provide a good elastic deformation space for the elastic member 44, improve the safety of the elastic member 44, help increase the number of elastic deformations, and extend the service life of the elastic member 44.

[0056] In some embodiments, in order to improve the connection stability between the handle 4 and the push rod 5, the push rod 5 is designed as a hollow rod body, so that the upper end of the push rod 5 is located between the first sliding channel 31 and the second sliding channel 32, and slides along the inner wall of the first sliding channel 31 to improve the sliding stability. At the same time, an assembly platform 51 is provided at one end of the push rod 5 close to the discharge port 21, and an assembly groove 511 is provided at one end of the assembly platform 51 facing the second cylindrical section 42, and the other end of the second cylindrical section 42 is assembled in the assembly groove 511. This arrangement allows the other end of the second cylindrical section 42 to be accurately assembled into the assembly groove 511, thereby achieving a firm connection between the handle 4 and the push rod 5. This connection method is not only simple and reliable, but also easy to manufacture and install. It should be noted that the shape of the other end of the second cylindrical section 42 is adapted to the assembly groove 511, so that the two can be stably connected.

[0057] The bottom end of the push rod 5 is in interference connection with the discharge port 21. Optionally, the bottom end of the push rod 5 is sleeved with a flexible sleeve, such as a rubber sleeve or a sponge sleeve, so that the bottom end of the push rod 5 can be inserted into the discharge port 21 to achieve a sealing effect; Optionally, the push rod 5 itself is made of a flexible material, such as a deformable plastic or wooden material, so that the bottom end of the push rod 5 can be inserted into the discharge port 21 to achieve an interference sealing effect; In this embodiment 1, the side wall of the push rod 5 close to the discharge port 21 is provided with an annular second groove 53, and the second groove 53 is sleeved with a sealing member 54, and the sealing member 54 is in interference connection with the discharge port 21. Preferably, the sealing member 54 is an O-ring. In other embodiments, the interference connection method between the push rod 5 and the discharge port 21 is not limited. It should be noted that the length of the push rod 5 must be such that when the push rod 5 is in interference connection with the discharge port 21, the top end of the push rod 5 is located in the first sliding channel 31 to prevent the push rod 5 from leaving the first sliding track during the rising air pressure to avoid malfunction.

[0058] Optionally, the discharge port 21 can be extended longitudinally to form a sealing channel, which can increase the sealing contact area between the sliding components. Therefore, the sealing member 54 can be at least two O-rings, or a flexible sleeve with at least two layers of sealing ridges. The specific structure is not limited, as long as it can achieve a sealing effect.

[0059] In order to make the push rod 5 more easily slide upward under the influence of air pressure, in some embodiments, a first air groove 512 is provided at one end of the assembly platform 51 facing the discharge port 21, an air hole 513 is provided between the first air groove 512 and the assembly groove 511, and a second air groove 421 is provided at the other end of the second cylindrical section 42 corresponding to the air hole 513. The first air groove 512, the air hole 513 and the second air groove 421 are interconnected, ensuring that the air pressure can be stably and efficiently transmitted to the push rod 5, thereby driving the push rod 5 to complete the unloading action. The interconnected air pressure transmission channels also help to reduce leakage and loss during the air pressure transmission process, thereby improving the efficiency and accuracy of the air pressure transmission.

[0060] In this embodiment 1, the elastic force of the elastic member 44 is smaller than the friction force of the interference connection between the push rod 5 and the discharge port 21; the elastic deformation length of the elastic member 44 is smaller than the length of the second sliding channel 32; the length of the second sliding channel 32 is smaller than the length of the first sliding channel 31, ensuring that the handle 4 can be sufficiently restricted and supported during the sliding process to prevent it from losing stability due to excessive length; the elastic deformation length of the elastic member 44 is 20mm-30mm, avoiding the generation of a large elastic force on the handle 4, ensuring that the elastic member 44 can provide sufficient reset force when subjected to air pressure, and at the same time will not lose stability due to excessive deformation.

[0061] The present invention also relates to a food processor, comprising a food processor body (not shown), a food processor cup body (not shown) and an elastic pneumatic material dropping mechanism mounted on the food processor cup body. A heating device (not shown) is provided in the food processor body. The pressure of the solution in the food processor cup body rises after being heated, providing air pressure for the feed port 11 to drive the sliding assembly to rise.

[0062] The working principle and steps of the present invention are as follows:

[0063] During installation, the elastic member 44 is assembled in the annular groove 43 of the handle 4, and then the handle 4 is passed through the second sliding channel 32 from above the material cover 3, and the assembly groove 511 of the push rod 5 is assembled with the handle 4 from the other end of the second sliding channel 32, and the top end of the push rod 5 is inserted between the first sliding channel 31 and the second sliding channel 32, and then the material cover 3 is assembled on the top of the silo 2, and the handle 4 is pressed to push the push rod 5 to slide toward the discharge port 21 until the push rod 5 is engaged with the trigger member 63. At this time, the push rod 5 is The rod 5 is connected to the discharge port 21 in an interference seal, and the air pressure Q1 in the cup cover 1 satisfies the following formula: N1+Q1<M1+M2+G1, wherein N1 is the elastic force of the elastic member 44, M1 is the friction force between the push rod 5 and the discharge port 21, M2 is the clamping friction force between the trigger member 63 and the push rod 5, and G1 is the total weight of the push rod 5 and the handle 4; at this time, there is no air pressure in the cup cover 1 or the air pressure value Q1 is small, and the push rod 5 remains stationary under the friction force between the trigger member 63 and the O-ring at the end of the push rod 5.

[0064] When the food processor sets the preset timing and the time reaches the heating time, the solution under the cup cover 1 is heated, Q1 increases, the pressure inside the food processor cup increases, and the pressure acts on the push rod 5. When the air pressure Q1+N1>M1+M2+G1, the push rod 5 and the handle 4 gradually move upward until the trigger member 63 is disengaged from the first card slot 52, and the push rod 5 is completely disengaged from the discharge port 21. The push rod 5 and the handle 4 continue to move upward under the action of the elastic member 44 until the maximum elastic range of the elastic member 44 is reached. At this time, the discharge port 21 is in an open state, and the material in the material bin 2 can enter the cup cover 1 from the discharge port 21 to complete the discharge. During the falling process, since the forces of M1 and M2 become 0 or decrease, the elastic force N1 of the elastic member 44 can easily support the total weight M1 of the push rod 5 and the handle 4, so that it always remains at the highest position, achieving an open state, convenient for discharge, and no jamming. The interference seal connection between the push rod 5 and the discharge port 21 and the clamping design between the trigger member 63 and the push rod 5 ensure that the blanking mechanism can maintain a stable state when blanking is not required. The blanking process is completely controlled by air pressure and does not require manual operation, thereby improving the degree of automation and production efficiency.

[0065] In summary, the elastic pneumatic material dropping mechanism and food processor provided by the present invention have the following technical effects:

[0066] 1. Through the feeding mechanism and feeding method, the bean ingredients do not need to be soaked in the cooking cup for a long time, thus effectively avoiding the problem of food deterioration caused by long-term soaking. This ensures the freshness of the ingredients and the quality and taste of the final food. Since the food deterioration is avoided, users can use the ingredients more efficiently and reduce the waste caused by food deterioration;

[0067] 2. The material dropping mechanism and method realize the function of automatic material dropping at a specified time by driving the handle 4 and the push rod 5 through air pressure. This greatly improves the automation of kitchen equipment and reduces the tediousness of manual operation. The automatic material dropping function enables the food processor to automatically start working at the time set by the user without manual waiting. This improves the use efficiency of kitchen equipment and saves precious time for users;

[0068] 3. The material-dropping mechanism ensures that the material-dropping mechanism can maintain a stable state when material-dropping is not required, through the interference seal connection between the push rod 5 and the material-dropping port 21 and the clamping design between the trigger member 63 and the push rod 5. This design effectively prevents accidental material-dropping or damage to the mechanism caused by external factors, reduces friction and wear of the mechanism during movement, and thus prolongs the service life of the equipment;

[0069] 4. The material dropping mechanism and method are not only applicable to the problem of pre-soaking beans, but also can be applied to other scenarios that require timed material dropping, which provides users with more choices and flexibility.

[0070] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
