The traditional cooking machine is usually equipped with a hopper, and the user needs to manually put the food materials into the hopper during use, and then start the machine for processing. However, with the popularization of smart home concept, the user's demand for intelligent cooking machine is increasing, especially the reservation start function, which allows the user to set the time in advance, so that the cooking machine starts working automatically at the specified time, greatly facilitating the user's daily life arrangement.

[0003] However, in the process of realizing the reservation function of the cooking machine, a key problem gradually emerges: if the food materials are mixed with water in advance and soaked for a long time, not only the loss of nutrients of the food materials may occur, but also the food materials may be deteriorated and mildewed due to bacterial growth, affecting food safety and taste. In order to solve this problem, some improvement schemes have been proposed in the prior art, for example, a cooking machine design disclosed in patent 202320387355.5, which stores the food materials and water separately and opens the hopper for discharging through a complex driving structure when needed, realizing safe feeding and processing of the food materials.

[0004] Although this technical scheme solves the problem of long-term soaking of food materials to some extent, it still has some shortcomings.

DETAILED DESCRIPTION

[0041] In order to better understand and implement, the following will be combined with the drawings of the utility model, the technical scheme in the embodiment of the utility model is clearly and completely described and discussed, obviously, only a part of the utility model described here, not all examples, based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor, belong to the protection scope of the utility model.

[0042] In order to facilitate the understanding of the embodiment of the utility model, the following will be combined with the drawings to further explain and illustrate specific embodiments, and each embodiment does not constitute the limitation of the embodiment of the utility model.

[0043] In the description of the utility model, it is necessary to explain that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and not indicating or implying that the indicated device or element must have a particular orientation, a particular orientation and operation, therefore, it cannot be understood as the limitation of the utility model.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing the specific embodiments, and are not intended to limit the utility model.

[0045] Embodiment 1 of the utility model refers to Figures 1-7As shown, a simple elastic pneumatic feeding mechanism and food processor are disclosed, which comprises a hopper 1, a cup cover 2, a material cover 3 and a sliding assembly 4. The cup cover 2 is used to cover the food processor cup on the top of the food processor body. The food processor is preferably a soybean milk machine. In other embodiments, the specific function and model are not limited. The bottom of the hopper 1 is provided with a discharge port 11, the top of the cup cover 2 is provided with a feeding port 21, the discharge port 11 communicates with the feeding port 21, and specifically, the discharge port 11 and the feeding port 21 are connected in a plug-in sealing manner. The feeding port 21 is used to provide air pressure for the discharge port 11. The material cover 3 is assembled on the top of the hopper 1, and the material cover 3 is provided with a first sliding channel 31 facing the discharge port 11. The sliding assembly 4 is slidably arranged in the first sliding channel 31, and the sliding assembly 4 and the discharge port 11 are in a sealed state and an open state. The first sliding channel 31 is further provided with an elastic member 5 for providing an upward thrust to the sliding assembly 4. When the sliding assembly 4 and the discharge port 11 are in a sealed state, the discharge port 11 is sealingly connected with the sliding assembly 4. Preferably, a sealing ring 423 is arranged between the discharge port 11 and the sliding assembly 4. When the air pressure rises to separate the sliding assembly 4 from the discharge port 11, the elastic member 5 drives the sliding assembly 4 to rise, and the sliding assembly 4 and the discharge port 11 are in an open state. By storing food materials in the hopper 1 and releasing them only when needed through air pressure control, the problem of premature mixing and long-term soaking of food materials with water is avoided, thereby effectively preventing the loss of nutrient components of food materials and the deterioration and mildewing caused by bacterial growth. The design uses a simple elastic pneumatic principle to drive the movement of the sliding assembly 4 through air pressure changes, avoiding the use of traditional complex mechanical drive structures. This not only reduces the manufacturing cost and maintenance difficulty of the equipment, but also significantly reduces energy consumption, meeting the requirements of energy saving and environmental protection.

[0046] In use, the sliding assembly 4 is placed into the first sliding channel 31 from above the material cover 3 and continues to be pressed downward along the first sliding channel 31 until the sliding assembly 4 reaches the lowermost end of the first sliding channel 31. At this time, the bottom end of the sliding assembly 4 is in interference sealing connection with the discharge port 11. When the solution below the cup cover 2 is heated, the air pressure in the cup cover 2 rises. When the air pressure can overcome the friction between the sliding assembly 4 and the discharge port 11, the sliding assembly 4 moves upward. At this time, the sliding assembly 4 is separated from the discharge port 11. The sliding assembly 4 gradually moves away from the discharge port 11 until it is not in contact. Then the elastic force of the elastic member 5 can drive the sliding assembly 4 to rise to an open state. The material in the hopper 1 can enter the cup cover 2 from the discharge port 11 to complete the feeding. The feeding process is completely controlled by air pressure without manual operation, improving the degree of automation and production efficiency.

[0047] In order to facilitate the filling, in some embodiments, the cover 3 is provided with a filling port 32, which is arranged away from the first sliding channel 31, and a rotatable filling cover 33 is arranged on the filling port 32. The design of the filling port 32 allows the user to conveniently add or replace food materials when the food processor is not working without disassembling the entire bin 1 or performing complex operations. In this embodiment 1, the filling port 32 and the filling cover 33 are in a fan ring shape, and a dial plate 331 and a rotating ring 332 are arranged on the filling cover 33. The rotating ring 332 is sleeved on the first sliding channel 31, and the dial plate 331 is used to rotate the filling cover 33 to cover or expose the filling port 32 with the first sliding channel 31 as the axis. This not only realizes flexible control of the filling port 32, but also ensures the sealing of the filling port 32 when the food processor is working normally. When it is necessary to add food materials, the user only needs to gently push the dial plate 331 to rotate the filling cover 33 to expose the filling port 32. After completing the addition of food materials, the user can rotate the filling cover 33 to cover the filling port 32 by gently pushing the dial plate 331.

[0048] In some embodiments, specifically, the sliding assembly 4 includes a handle 41 and a push rod 42 connected to each other, and the connection between the handle 41 and the push rod 42 includes but is not limited to clamping, bonding or screwing. One end of the handle 41 is connected to the push rod 42 through the first sliding channel 31, the push rod 42 is sealingly connected to the discharge port 11, and the other end of the handle 41 is limited outside the first sliding channel 31 away from the discharge port 11.

[0049] In order to improve the stability of the longitudinal sliding of the handle 41 and the push rod 42, in some embodiments, the first sliding channel 31 extends in the direction of the discharge port 11 and has a first lip 311, and the first sliding channel 31 extends in the direction away from the discharge port 11 and has a second lip 312. The second lip 312 is continuously bent twice in the first sliding channel 31 to form a second sliding channel 313. The handle 41 slides in the second sliding channel 313, and the push rod 42 slides in the first sliding channel 31. This ensures that the handle 41 and the push rod 42 can stably move therein, improves the overall sliding stability, and easily moves the sliding assembly 4 in the sliding channel by holding the handle 41. The push rod 42 part is the part of the sliding assembly 4 that directly acts on the discharge port 11 to ensure that the discharge port 11 can be stably opened or closed during the pushing process.

[0050] In order to limit the handle 41, in some embodiments, the handle 41 is provided with an abutting edge 4111 at one end away from the push rod 42, which is used to abut with the top end of the second sliding channel 313 to avoid the handle 41 from sliding completely into the second sliding channel 313. The abutting edge 4111 provides an additional fixing or limiting point for the handle 41, ensuring that the handle 41 can be stably stopped at a certain position when the air pressure is insufficient or the material is not needed to be discharged.

[0051] In some embodiments, the handle 41 is further improved, specifically, the handle 41 comprises a first cylindrical segment 411, a second cylindrical segment 412 and an annular groove 413, the cross-sectional area of the second cylindrical segment 412 is smaller than that of the first cylindrical segment 411; the abutting edge 4111 is arranged at one end of the first cylindrical segment 411, one end of the second cylindrical segment 412 is connected to the other end of the second cylindrical segment 412, and both are coaxial, the first cylindrical segment 411 can slide in the second sliding channel 313, the second sliding channel 313 is bent inwardly near the direction of the discharge port 11 to form a third abutting edge 4111, the third abutting edge 4111 abuts with the side surface of the second cylindrical segment 412 to improve the sliding stability of the second cylindrical segment 412, therefore the length of the third abutting edge 4111 is equal to the difference between the radius of the first cylindrical segment 411 and the second cylindrical segment 412, the other end of the second cylindrical segment 412 is connected with the push rod 42 through the center of the third abutting edge 4111, the annular groove 413 is arranged at the other end of the first cylindrical segment 411 and along the circumferential outside of the second cylindrical segment 412. The annular groove 413 is formed by extending inwardly along the surface of the second cylindrical segment 412 to the first cylindrical segment 411, which is used to install an elastic member 5, the elastic member 5 is preferably a spring, one end of the elastic member 5 abuts with the annular groove 413 and the other end abuts with the third abutting edge 4111, in normal state, the elastic force of the elastic member 5 is greater than the gravity of the handle 41 and the push rod 42, which can lift them to make the sliding assembly 4 in the open state, the elastic member 5 can also ensure that the handle 41 will not fall due to gravity and cause bumping, providing a buffering effect for the handle 41 to avoid noise. At the same time, the second sliding channel 313, the third abutting edge 4111 and the annular groove 413 provide a good elastic deformation space for the elastic member 5, improving the safety of the elastic member 5, helping to improve the number of elastic deformation and prolong the service life of the elastic member 5.

[0052] In order to make the push rod 42 more easily affected by the air pressure and slide upward, in some embodiments, a first air groove 4212 is arranged at one end of the assembly platform 421 towards the discharge port 11, an air hole 4213 is arranged between the first air groove 4212 and the assembly groove 4211, a second air groove 4121 is arranged at the other end of the second cylindrical segment 412 corresponding to the air hole 4213, the first air groove 4212, the air hole 4213 and the second air groove 4121 are interconnected, which ensures that the air pressure can be stably and efficiently transmitted to the push rod 42, thereby driving the push rod 42 to complete the discharging action, and the interconnected air pressure transmission channel also helps to reduce the leakage and loss in the air pressure transmission process, thereby improving the efficiency and accuracy of the air pressure transmission.

[0053] In the embodiment 1, the elastic force of the elastic member 5 is smaller than the friction force of the interference connection between the push rod 42 and the discharge port 11; the elastic deformation length of the elastic member 5 is smaller than the length of the second sliding channel 313; the length of the second sliding channel 313 is smaller than the length of the first sliding channel 31; and the elastic deformation length of the elastic member 5 is 20-30 mm. The length limitation can ensure that the sliding assembly 4 has sufficient moving distance under the action of air pressure, so as to realize the complete opening of the discharge port 11, and can also avoid generating excessive inertial force or impact force during the movement of the sliding assembly 4, thereby affecting the stability and service life of the mechanism.

[0054] Preferably, in some embodiments, a first sliding rail 422 is arranged on the push rod 42, and a second sliding rail 314 is arranged in the first sliding channel 31 and is in sliding connection with the push rod 42, so that the push rod 42 can always maintain a stable trajectory during movement, thereby avoiding mechanism failure or damage caused by deviation or shaking, reducing the friction resistance and wear degree of the mechanism, and prolonging the service life of the mechanism.

[0056] In summary, the simple elastic pneumatic feeding mechanism and the food processor provided by the utility model have the following technical effects.

[0057] 1. By storing food materials in the hopper 1 and controlling the release by air pressure when needed, the problem of food materials being mixed with water in advance and soaked for a long time is effectively avoided. This helps to maintain the nutritional ingredients of the food materials and prevent the loss of nutrients due to long-term soaking;

[0058] 2. Food materials soaked for a long time are prone to bacterial growth, causing spoilage and mold. The feeding mechanism can ensure that the food materials are put in a fresh state, greatly reducing the risk of food spoilage and mold, thereby ensuring food safety and taste;
