Description

TECHNICAL FIELD

[0001] The present application relates to the field of food processors, in particular to a portable food processor. BACKGROUND

[0002] The existing food processor generally includes a base and a mixing cup, the base is provided with a motor, the mixing cup is provided with a crushing knife, the motor drives the crushing knife to rotate to realize the stirring and crushing of the material, in order to improve the multifunctionality of the food processor, the food processor is also provided with a heating device to heat and cook the material in the mixing cup to realize the preparation of hot drinks and cooked food, etc., which greatly improves the user experience and satisfaction. Generally, in order to transmit power and transmit power in the base to the stirring knife in the cup body, the lower part of the mixing cup is provided with an electrical coupling device and a coupling device and other power transmission devices, in order to ensure the safety of the electrical appliance and avoid scalding caused by the exposure of the heating device, the electrical coupling device and the heating device are generally shielded by the cup seat, the upper coupling device is arranged in the center of the cup seat, and the lower coupling device matched with the upper coupling device is arranged in the center of the base, so as to ensure that the power is effectively transmitted to the crushing knife, these need to occupy a certain space, and the setting of these accessories also increases the weight of the cup body and the size of the food processor.

[0003] Therefore, the existing food processors are large in size, occupy space, and are heavy, and are inconvenient to take and place, especially for the elderly, and are inconvenient for consumers to use or place and store when idle. In addition, young people are now busy with work and have a fast pace of life, and the existing food processors have a large production capacity, which is not convenient for office or home use. Although a small food processor has appeared on the market, the smallest one is still 500ml, which still exceeds the amount required for personal drinking, and is easy to become sour in summer, causing waste. At the same time, everyone achieves this by reducing the size of the base, and the motor occupies a large space in the base, so the motor becomes smaller to make the base size smaller, but at the same time the motor becomes smaller and the power becomes smaller. In order to ensure the amount of pulp and prevent splashing of the pulp or material during crushing, or overflow of the pulp from the cup body during boiling, the utilization rate of the food processor cup body is low, so the size of the pulp is still small and the size of the cup body cannot be controlled. Therefore, the actual cup size of the existing small food processor does not change much, and due to the smaller motor power, when the material is stirred and crushed, in order to ensure the processing efficiency of a single time, the material is stirred and crushed by the crushing knife, and due to the influence of the motor power, the upper layer of material cannot move to the lower layer to be cut and crushed by the crushing knife, or the upper layer of material moves slowly, greatly increasing the material crushing time and reducing the crushing efficiency, and the crushing effect is general, which will cause the processing efficiency to decrease and the taste of the prepared beverage to deteriorate. In addition, in order to ensure the amount of pulp, and in order to ensure the overall size of the food processor on the market, the small capacity machine is still large, which is not convenient for personal or office or travel use.

[0004] Therefore, there is an urgent need for a small food processor that is small in size, has sufficient effective capacity, and has high crushing efficiency. SUMMARY

[0028] After the above technical solution is adopted, the present application has the following advantages:

[0029] 1、The motor is fixedly connected with the inner cup, and the inner space of the lower end of the shell forms a base for accommodating the motor, so that a separate base is not needed, the bottom of the inner cup does not need to be provided with an electrical transmission coupling device, a cup seat for shielding the electrical coupling device for safety is not needed, and a shaft coupling or other power transmission device is not needed, so that the power transmission efficiency is high, the space occupied by the whole machine in the height direction is greatly reduced, the whole machine is small, the base and the cup body are integrated, and the machine is more portable. Meanwhile, the maximum slurry preparation capacity scale line is arranged on the side wall of the inner cup, so that the added materials and liquids do not exceed the scale line, the motor load is reasonable during crushing, the motor running effect and the crushing effect of the crushing knife are best when the motor drives the crushing knife to crush, the capacity and the power matching effect of the heating device of the machine are best, so that the efficiency during the cooking process is highest, the taste of the prepared slurry is best, the cooking degree is high, and the customer satisfaction is improved. The processing cavity of the food processor includes a maximum slurry preparation space and a tumbling space, the maximum slurry preparation space is a space for containing materials and liquids, under the condition that the capacity of the cup body is unchanged, the maximum slurry preparation space and the tumbling space are arranged to remind the user that the storage space of the materials and the water cannot exceed the maximum slurry preparation capacity scale line, so as to ensure the crushing and cooking effects, and the maximum slurry preparation space and the tumbling space are arranged to ensure that the motor drives the crushing knife to rotate, so that the liquid moves with the materials, the crushing knife collides with the materials and cuts the materials, the liquid and the materials can have enough space to form a tumbling movement path, the effective movement of the materials in the processing cavity is strengthened, the materials can be tumbled up, down, left and right, so that all the materials can be cut and crushed by the crushing knife, the crushing efficiency of the materials is greatly improved, some materials are not cut and crushed, and large-particle materials exist, the crushing effect of the materials is well ensured and improved, and the materials will not run out of the processing cavity during the tumbling movement, so that the maximum slurry preparation capacity is ensured to the greatest extent, and the slurry and the materials will not tumble and overflow out of the cup body during the slurry preparation process, and the crushing effect and the cooking effect are ensured to the greatest extent. The maximum slurry preparation space is the space between the cup bottom of the inner cup and the maximum slurry preparation capacity scale line, the capacity of the maximum slurry preparation space is V1, V1 is 300ml to 400ml, the capacity of the tumbling space is V2, 0.8 is less than or equal to V2 / V1 and is less than or equal to 1.5, so that the capacity of the single processing material is sufficient and can meet the needs of the user, and the tumbling space is greater than the maximum slurry preparation space, so that the materials can form sufficient tumbling in the processing cavity, the contact probability of the materials and the crushing knife is greatly increased, and the crushing efficiency and the crushing effect of the materials are improved.When V1 is less than 300ml, the capacity of the maximum pulping space is too small, and the amount of material processed in a single process is too small to meet the needs of users; when V1 is greater than 400ml, the capacity of the maximum pulping space is too large, reducing the size of the tumbling space, so that the material cannot be fully tumbled, affecting the crushing efficiency and crushing effect of the material; in addition, when V2 / V1 is less than 0.8, the capacity of the maximum pulping space is too small, and the amount of material processed in a single process is too small to meet the needs of users, and also reduces the single processing efficiency; when V2 / V1 is greater than 1.5, the maximum pulping space is too large, so that the tumbling space is too small, affecting the crushing efficiency and crushing effect.

[0030] 1≤V2 / V1≤1.2, so that the size ratio of the maximum pulping space and the tumbling space is optimal and most reasonable, which can well ensure that the capacity of the maximum pulping space is large enough to ensure the single processing efficiency, and the tumbling space is also large enough to ensure that the material can be fully tumbled, thereby increasing the contact probability of the material and the crushing knife to improve the crushing efficiency and crushing effect.

[0031] And the capacity V2 of the tumbling space satisfies the condition 0.8≤V2 / V1<1.5, which ensures the boiling effect of the slurry and at the same time makes the space occupied by the cup with the largest capacity smallest, which meets the requirements of pulping amount and boiling and crushing. The capacity V3 of the installation space formed between the bottom of the inner cup and the outer shell is set in the range of 0.8≤V3 / V1≤1.2, and the motor and the circuit board are arranged in the installation space, the motor is installed at the bottom of the inner cup, the lower end of the motor abuts against the outer shell, and the circuit board is arranged around the motor, so that the entire food processor can have a smaller vertical size and a simplest structure, thereby greatly reducing the overall size of the food processor, i.e. reducing the overall height of the food processor, making the overall structure of the food processor compact, not occupying space, easy to store, and realizing the miniaturization and portability of the food processor. When V3 / V1 is less than 0.8, the installation cavity is too small to facilitate the installation of the motor and the circuit board, and the heat dissipation effect of the motor and the circuit board is not good, which affects the working stability of the motor and the circuit board, thereby being not conducive to crushing and affecting the pulping effect of the food processor; when V3 / V1 is greater than 1.2, although the installation space of the motor and the circuit board is large, which facilitates production and installation, but the installation cavity is too large, which is not good for miniaturization and is not convenient for carrying, and in order to ensure the miniaturization of the overall structure, the capacity of the cup is insufficient to meet the customer's demand for pulping amount, or the tumbling space is insufficient, which will cause the splashing of slurry or material during crushing, or the insufficient rising space of the slurry during boiling, which will cause the problem of overflow, thereby reducing the boiling efficiency and the boiling effect of the slurry, and also having a great influence on the quality of the pulping.

[0032] 2、The rolling space is set as the space between the maximum capacity scale line of pulping and the lower end surface of the cup cover, which ensures that the rolling space is large enough and facilitates the rolling of the material in the rolling space, so as to improve the contact probability between the material and the crushing knife, thereby greatly improving the crushing efficiency and crushing effect. At the same time, during the crushing process, the rolling of the material and the slurry will not be sprayed out of the cup opening, ensuring the safety of pulping and avoiding the pollution of the desktop by the sprayed slurry.

[0033] 3、By setting the downward extending surrounding edge on the cup cover, and after the cup cover is installed in place, the surrounding edge is arranged in abutment with the inner side wall of the inner cup, which prevents the slurry from overflowing from the fitting gap between the surrounding edge and the inner side wall of the inner cup, and also prevents the material from being stuck in the fitting gap between the surrounding edge and the inner side wall of the inner cup, ensuring that the material is completely crushed. The rolling space is the space between the maximum capacity scale line of pulping and the lower end of the surrounding edge, which ensures that the rolling space is large enough to ensure the crushing efficiency and crushing effect, and makes the material less likely to be stuck in the fitting gap between the surrounding edge and the inner side wall of the inner cup, greatly improving the effective crushing efficiency of the material. At the same time, during the crushing process, part of the material that climbs along the inner side wall of the inner cup to the cup cover changes its movement path under the action of the surrounding edge of the cup cover, and folds back to the center downward, and then quickly flows back to the crushing knife under the action of gravity for crushing, greatly improving the crushing efficiency. The surrounding edge can also block the liquid and the material to some extent, ensuring that the liquid and the material will not be sprayed to the cup opening, avoiding the problem of spraying injury.

[0034] 4、A sealing ring is arranged between the surrounding edge and the inner side wall of the inner cup. By arranging the sealing ring, the sealing property between the surrounding edge and the inner side wall of the inner cup is improved, thereby better preventing the slurry from overflowing. At the same time, the thickness of the surrounding edge is set to be in the range of 3mm to 6mm, which ensures that the strength of the surrounding edge is sufficient, and when the interference fit is formed between the sealing ring and the inner side wall of the inner cup, the surrounding edge will not be deformed, thereby ensuring the sealing property and the durability of the surrounding edge and the cup cover. At the same time, the surrounding edge with this thickness can block the upward movement of the slurry and the material. Since the crushing knife is driven to move by the motor, under the action of the centrifugal force of the crushing knife, the slurry and part of the material will move upward along the cup wall, encounter the surrounding edge, and then fold back downward to fall back into the cup body under the action of the reaction force of the surrounding edge and the gravity. A small part of the slurry or the material that is sprayed upward will also encounter the cup cover and completely change its movement direction to fall back into the cup body, thereby preventing the outward spraying of the material or the slurry during the stirring and crushing process, and avoiding the overflow of the slurry or the material from the cup opening. When the thickness is less than 3mm, the thickness is too thin and is prone to deformation, which affects the sealing effect and the blocking effect of the slurry overflow, and causes the slurry or the material to splash out of the cup opening. When the thickness is greater than 6mm, the thickness is too thick, which wastes materials and is prone to shrinkage and deformation during processing and molding. At the same time, the buffer space for the upward rolling of the slurry will be reduced, which will also affect the overflow of the slurry from the overflow port without buffer space.

[0035] 5. By setting a spout on the cup mouth, the spout acts as a guide when pouring out the slurry, making it easier for the slurry to be poured into the container. There is also a vent on the rim corresponding to the spout, located above the sealing ring. This allows the heat generated during heating to be discharged in time through the vent, preventing the inner cup from bursting due to excessive heat and ensuring the safety of the food processing machine during operation.

[0036] 6. The rim is also provided with an overflow port corresponding to the spout. The overflow port and the vent are the same, which facilitates the processing of the lid. At the same time, it ensures that the pressure inside the cup body will not be too high when heated. When the pressure is high, the slurry can flow out from the vent, which is the overflow port, and can also return to the inside of the cup body, ensuring the breathability of the vent and improving the efficiency and effect of cooking.

[0037] 7. By setting inwardly protruding baffles on the inner wall of the inner cup, when the material is being crushed, some of the material that climbs up to the top of the baffles along the inner wall of the inner cup changes its movement path under the action of the baffles, turning downward and back towards the center, and quickly flowing back to the vicinity of the crushing blade under the action of gravity for further crushing. At the same time, it can enhance the degree of tumbling of the material in the processing chamber, thereby increasing the probability of contact between the material and the crushing blade, thus improving the crushing efficiency and crushing effect. At this time, the tumbling space is the space from the maximum pulping capacity scale line to the top of the baffles. Under the dual action of the baffles and the tumbling space, the degree of tumbling of the material in the processing chamber is greatly enhanced, thereby further improving the crushing efficiency and crushing effect. At the same time, when heating and cooking, the slurry surges upward under the action of heat and tumbles to this point under the action of inertia. Under the action of the baffles, it also moves downward and towards the center, so that the heat circulates fully from the outside to the inside, which is conducive to thorough cooking.

[0038] 8. The protrusion height of the baffle ribs gradually decreases from top to bottom, and the width of the baffle ribs gradually narrows from top to bottom. Since the lower end of the baffle ribs is closer to the crushing blade, the material at the lower end of the baffle ribs is generally crushed very well. This setting enhances the turbulence effect at the upper end of the baffle ribs, which is conducive to the slurry and material concentrating downwards and towards the middle, and then being carried up by the blades and flowing back. This cycle repeats, resulting in thorough tumbling and crushing. In other words, when the material moves to the upper end, it is blocked by the baffle ribs and quickly falls back into the effective crushing area of ​​the crushing blade, thereby increasing the probability of contact and collision between the material and the crushing blade, thus greatly improving the crushing effect and crushing efficiency.

[0039] 9、The distance between the upper end of the spoiler rib and the cup opening is C, 20mm≤C≤30mm, that is, the upper end of the spoiler rib does not extend to the cup opening completely, so that when the material collides with the upper end of the spoiler rib, the material can be folded back under the action of the spoiler rib due to the certain distance between the upper end of the spoiler rib and the cup opening, thereby falling back to the effective crushing area of the crushing knife, providing a buffer space for the few liquid streams that continue to flow, preventing the material and liquid from overflowing from the cup opening during crushing or boiling, ensuring that the liquid and the material cannot splash to the cup opening, preventing the problem of splashing and injuring people, improving the crushing efficiency and crushing effect of the material, and ensuring the safety of the food processing machine during pulping. In addition, when C is less than 20mm, the distance is too small, and the material is easy to overflow from the cup opening; when C is greater than 30mm, the distance is too large, reducing the longitudinal length of the spoiler rib and reducing the spoiler effect of the spoiler rib.

[0040] 10、By specifically providing the shell to include a shell body and a bottom cover arranged at the bottom of the shell body, the inner cup is specifically arranged in the shell body, and a mounting cavity is formed between the bottom of the inner cup and the bottom cover, the motor is located in the mounting cavity, the lower end of the motor abuts against the bottom cover, and the circuit board is transversely arranged in the mounting space and surrounds the motor. In this way, a separate base does not need to be arranged, and a mounting cavity is formed between the bottom of the inner cup and the bottom cover to accommodate the motor and the circuit board, thereby greatly reducing the vertical size of the food processing machine as a whole, that is, reducing the height of the food processing machine as a whole, miniaturizing the food processing machine, not occupying space, and being easy to store. Meanwhile, the mounting cavity is sufficient to ensure the heat dissipation effect of the motor, thereby ensuring the continuity and stability of the operation of the motor.

[0057] The present application will be further described below in conjunction with the drawings and specific embodiments. It should be understood that the following "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "vertical", "horizontal", "top", "bottom" and other words indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device / component must have a particular orientation or be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation of the present application.

[0058] Example 1:

[0059] like Figures 1 to 3 As shown, this invention provides a food processing machine with high pulverization efficiency, including an inner cup 1, an outer shell 2 fitted over the inner cup 1, and a heating device 3 located at the bottom of the inner cup 1. The heating device 3 includes a heating element 31, which not only has high heating efficiency but also a simple structure, making it easy to manufacture and assemble. A motor 4 is located inside the outer shell 1 and below the bottom of the inner cup 2. The motor 4 includes a motor shaft 41. The bottom of the inner cup 1 has a through hole through which the motor shaft 41 passes and extends into the inner cup 1. A pulverizing blade 5 is located at the upper end of the motor shaft 41. This eliminates the need for a coupling and saves space, making power transmission more efficient and reliable. It also eliminates the need for electrical transmission devices such as couplers or connectors. Furthermore, the inner cup is directly enclosed by the outer shell, and the outer shell extends to form the installation space for the motor and circuit board with the bottom of the inner cup, eliminating the need for a cup holder structure. This greatly saves the space of the entire machine, thereby reducing the overall structural size and laying the foundation for the miniaturization of food processing machines. The inner cup 1 of this invention includes a cup mouth 11, and a cup lid 6 is provided at the cup mouth 11. The cup lid 6 and the inner cup 1 together form a processing cavity 71. Specifically, the inner cup 1 is a metal inner cup, specifically a stainless steel inner cup, the outer shell 2 is a plastic outer shell, specifically an ABS (acrylonitrile-butadiene-styrene) outer shell, and the cup lid 6 is a plastic cup lid. Using a stainless steel inner cup not only ensures the hygiene and health of the food produced, but also the inner surface of the stainless steel inner cup is smooth and easy to clean. Of course, the side of the cup lid 6 that contacts the processing cavity 71 can also be made of metal, so that the entire processing cavity 71 is completely metal, which can better ensure the hygiene and health of the food produced.

[0060] In this embodiment, the capacity of the processing cavity 71 is V, 600ml≤V≤800ml, and V is specifically 700ml. Not only is the capacity of the food processor sufficient to ensure single processing efficiency and meet the basic needs of consumers, but the vertical height of the food processor is also not unnecessarily increased, thereby reducing the vertical height of the food processor, and thus reducing the vertical size of the food processor, so that the food processor can be better miniaturized. At the same time, the inner side wall of the inner cup 1 is provided with a maximum capacity scale line 12 and a minimum capacity scale line 13 for pulping, so that the added materials and liquids do not exceed the scale line, so that the motor load is reasonable during crushing, and the motor runs optimally and the crushing knife crushes the materials optimally when the motor drives the crushing knife to crush. This capacity and the power of the heating device of the machine are best matched, so that the efficiency during cooking is highest, the taste of the prepared slurry is best, the cooking degree is high, and the customer satisfaction is improved. Moreover, the processing cavity 71 includes a maximum pulping space 711 and a tumbling space 712. The maximum pulping space is the space for storing materials and liquids. Under the condition that the capacity of the cup body remains unchanged, the maximum pulping space and the tumbling space are provided to remind the user that the storage space of the materials and water cannot exceed the scale line of the maximum pulping capacity, so as to ensure the crushing and cooking effect. At the same time, by providing the maximum pulping space and the tumbling space, the motor drives the crushing knife to rotate, so that the liquid moves with the materials. When the crushing knife collides with and cuts the materials, the liquid and the materials can have enough space to form a tumbling movement path, so as to strengthen the effective movement of the materials in the processing cavity, so that the accumulated materials can produce tumbling movement up, down, left and right, so that all the materials can be cut and crushed by the crushing knife, greatly improving the crushing efficiency of the materials, avoiding that some materials are not cut and crushed or are not cut sufficiently, and there are large particles of materials, which well ensures and improves the crushing effect of the materials. At the same time, the materials will not run out of the processing cavity during the tumbling movement, thereby maximizing the amount of pulping, and the slurry and materials will not tumble out of the cup body during the pulping process, which can maximize the crushing effect and the cooking effect. While ensuring the maximum pulping amount, the materials and the slurry are given enough tumbling space to ensure the crushing effect, and will not splash and overflow, thereby improving the utilization rate of the processing cavity of the stirring cup, reducing the volume of the stirring cup, and further reducing the size and volume of the food processor.

[0061] Specifically, the maximum pulping space 711 is the space between the bottom of the inner cup 1 and the maximum pulping capacity scale line 12, and the capacity of the maximum pulping space 711 is V1, V1 is 300-400 ml, and V1 is specifically 300 ml. The capacity of the tumbling space 712 is V2, and 0.8≤V2 / V1≤1.5. In this way, the capacity of the single processing material is sufficient to meet the needs of the user, and the tumbling space is set to be larger than the maximum pulping space to ensure that the tumbling space is large enough to enable the material to form sufficient tumbling in the processing cavity, thereby greatly increasing the contact probability of the material and the crushing knife to improve the crushing efficiency and crushing effect of the material.

[0062] At the same time, 1≤V2 / V1≤1.2, and V2 / V1 is specifically 1, i.e. V2 is specifically 300 ml. In this way, the capacity of the maximum pulping space is sufficiently large to ensure the processing efficiency of a single material, and the tumbling space is also sufficiently large to ensure that the material can tumble sufficiently, thereby increasing the contact probability of the material and the crushing knife to improve the crushing efficiency and crushing effect. At the same time, the tumbling space 712 is the space between the maximum pulping capacity scale line 12 and the lower end surface of the cup cover 6. This ensures that the tumbling space is sufficiently large, and at the same time facilitates the tumbling of the material in the tumbling space to improve the contact probability between the material and the crushing knife, thereby greatly improving the crushing efficiency and crushing effect.

[0063] Specifically, the cup cover 6 is provided with a downwardly extending surrounding edge 61. After the cup cover 6 is installed in place, the surrounding edge 61 is arranged in abutment with the inner side wall of the inner cup 1. At this time, the tumbling space 712 is the space between the maximum pulping capacity scale line 12 and the lower end of the surrounding edge 61. This prevents the pulp from overflowing from the fitting gap between the surrounding edge and the inner side wall of the inner cup, and also prevents the material from being stuck in the fitting gap between the surrounding edge and the inner side wall of the inner cup, ensuring that the material is completely crushed. The tumbling space is the space between the maximum pulping capacity scale line and the lower end of the surrounding edge, which ensures that the tumbling space is sufficient to ensure the crushing efficiency and crushing effect, and prevents the material from being stuck in the fitting gap between the surrounding edge and the inner side wall of the inner cup, thereby greatly improving the effective crushing efficiency of the material. At the same time, during crushing, the material that climbs along the inner side wall of the inner cup to the cup cover changes its movement path under the action of the surrounding edge of the cup cover, folds back towards the center, and quickly flows back to the vicinity of the crushing knife under the action of gravity for crushing, thereby greatly improving the crushing efficiency. The surrounding edge also blocks the liquid and the material to some extent, preventing the liquid and the material from splashing into the cup opening and causing injury.

[0064] And, in order to improve the sealing, a sealing ring 62 can be provided between the rim 61 and the inner side wall of the inner cup 1, the sealing ring 62 is an O-shaped sealing ring, and the sealing ring 62 is specifically a silica gel sealing ring. By providing the sealing ring, the sealing between the rim and the inner side wall of the inner cup is increased, so as to better prevent the slurry from overflowing. The thickness S of the rim 61 is 3mm-6mm, and S is specifically 5mm. The strength of the rim is sufficient, and when the interference fit is formed between the sealing ring and the inner side wall of the inner cup, the rim will not be deformed to ensure the sealing. At the same time, it can also ensure that the material will not be deformed when it hits the rim, and ensure the durability of the rim and the cup cover. At the same time, the rim with this thickness can block the upward movement of the slurry and the material. Since the crushing knife is driven by the motor to move, under the centrifugal force of the crushing knife, the slurry and part of the material will move upward along the cup wall, meet the rim, and under the action of the reaction force of the rim and gravity, the slurry and the material will turn back and fall back into the cup body. A small part of the slurry or material is sprayed upward, and also meets the cup cover to completely change the direction of movement and falls back into the cup body. It prevents the outward spatter of the material or the slurry during the process of stirring and crushing, and avoids the overflow of the slurry or the material from the cup opening.

[0065] In order to facilitate pouring food, a cup spout 111 can be provided on the cup opening 11. In this way, when the slurry is poured out, the cup spout 111 plays a role of guiding flow, and the slurry is poured into the container. A gas vent 611 corresponding to the cup spout 111 is provided on the rim 61, and the gas vent 611 is located above the sealing ring 62. In this way, the heat generated during heating can be discharged in time from the gas vent, so as to avoid the explosion of the inner cup due to the excessive heat in the inner cup, and ensure the safety of the food processor during work.

[0066] In order to ensure the anti-overflow effect of the food processor, the overflow port 612 can be arranged on the surrounding edge 61. After the cup cover 6 is installed in place, the lower end surface of the cup cover 6 covers the cup nozzle 111, the surrounding edge 61 is sealed to the inner side wall of the inner cup 1, and the overflow space 72 is formed between the lower end surface of the cup cover 6. The lowest part of the overflow port 612 to the inner top surface of the cup cover 6 forms a buffer space 713. The overflow space 72 and the buffer space 713 are communicated through the overflow port 612. In this way, by forming the buffer space and the overflow space, when the food processor is working, the buffer space first buffers the slurry to slow down the impact force of the slurry overflowing outward. Even if some slurry enters the overflow space through the overflow port, it can well prevent the slurry from directly overflowing. Since the overflow space has a certain capacity, it can collect a small amount of overflowing slurry. When the slurry falls back, the slurry can flow back to the processing cavity through the overflow port to avoid waste of the slurry. In this way, the anti-overflow effect of the food processor can be improved. Of course, in the embodiment, in order to simplify the structure, the air vent 611 and the overflow port 612 are combined into one, that is, there is only one port. The overflow port 612 not only plays the role of air permeability, but also discharges the overflowing slurry from the buffer space to the overflow space. Moreover, the overflow port 612 is located above the sealing ring 62. In this way, when the slurry rises, the slurry can only enter the overflow space from the overflow port. After the cup cover is installed in place, the overflow space is formed between the sealing ring and the lower end surface of the cup cover. The overflow space formed in this way not only has sufficient capacity, but also has good sealing performance and can accommodate more overflowing slurry, thereby better preventing the slurry from directly overflowing from the cup opening.

[0067] The buffer space 713 is located above the tumbling space 712, that is, the maximum slurry space 711, the tumbling space 712 and the buffer space 713 together form the processing cavity 71. Specifically, the capacity V of the processing cavity 71 is 700 ml, V1 is 300 ml, V2 is 360 ml, and the buffer space 713 is 40 ml. In this way, the capacity of the single processing material is sufficient to meet the needs of users. At the same time, by arranging the tumbling space, the material can form sufficient tumbling in the processing cavity, thereby greatly increasing the contact probability of the material and the crushing knife to improve the crushing efficiency and crushing effect of the material. Moreover, the buffer space can well prevent the slurry from overflowing during cooking, thereby greatly improving the anti-overflow effect of the food processor.

[0068] In order to reduce the risk of slurry overflow, the vertical height of the overflow port 612 can be set to 4mm-10mm, specifically 7mm, and the distance between the overflow port 612 and the lower end of the surrounding edge 61 is E, 8mm≤E≤15mm, and E is specifically 11mm. In this way, the size of the overflow port is sufficient to ensure that the slurry overflowing from the buffer space can flow smoothly into the overflow space. At the same time, due to the distance E, the slurry hitting the lower end of the surrounding edge will not directly flow out of the overflow port, so that the surrounding edge can effectively prevent the slurry from overflowing. At the same time, during the cooking process, the heat in the inner cup can be discharged through the overflow port, which effectively reduces the pressure in the inner cup and reduces the risk of slurry overflow.

[0069] In order to better improve the sealing performance, the cup cover 6 includes a lower end surface 64 and an inner top surface 65. The surrounding edge 61 can be arranged on the lower end surface 64 of the cup cover 6 and close to the outer edge of the cup cover 6. A distance D is arranged between the surrounding edge 61 and the outer edge of the cup cover 6, and 6mm≤D≤8mm, and D is specifically 7mm. In this way, the surrounding edge is not only convenient for setting, but also convenient for the surrounding edge and the cup cover to be processed and formed together, so as to ensure the production and processing efficiency. By arranging the distance D, the surrounding edge can be conveniently extended into the inner cup, and the interference fit between the sealing ring and the inner side wall of the inner cup is also facilitated, so as to ensure the sealing performance between the sealing ring and the inner side wall of the inner cup.

[0070] More specifically, the inner top surface 65 of the cup cover 6 is higher than the lower end surface 64 of the cup cover 6. In this way, the space of the buffer space is increased, and when the slurry rises, the inner top surface 65 of the cup cover 6 can effectively block and buffer the slurry, greatly enhancing the buffering effect of the buffer space.

[0071] In order to ensure that the surrounding edge can better block and buffer, the length L of the surrounding edge 61 extending into the inner cup 1 can be set to 15mm-35mm, and L is specifically 25mm. In this way, the length between the surrounding edge and the inner side wall of the inner cup is sufficient to ensure the sealing performance between the cup cover and the inner cup. At the same time, when the slurry rises, the surrounding edge can also block and buffer the slurry.

[0072] In order to improve the crushing efficiency and crushing effect, the inner side wall of the inner cup 1 is provided with inwardly protruding turbulence ribs 14. When the material is crushed, part of the material along the inner side wall of the inner cup climbs to the top end of the turbulence rib under the action of the turbulence rib. The movement path changes and folds back downward and centrally, and quickly flows back to the vicinity of the crushing knife under the action of gravity for further crushing. At the same time, the tumbling degree of the material in the processing cavity is enhanced to improve the contact probability between the material and the crushing knife, thereby improving the crushing efficiency and crushing effect of the material. At this time, the tumbling space is the space from the maximum capacity scale line of pulping to the upper end of the turbulence rib. Under the dual action of the turbulence rib and the tumbling space, the tumbling degree of the material in the processing cavity is greatly enhanced, thereby further improving the crushing efficiency and crushing effect of the material. At the same time, when heated and boiled, the slurry is driven upward by heat and tumbles under the action of inertia. The slurry is affected by the turbulence rib and moves downward and centrally, so that the heat is fully circulated from the outside to the inside, which is beneficial to the full boiling.

[0073] More specifically, the protruding height of the turbulence rib 14 gradually decreases from top to bottom, and the width of the turbulence rib 14 gradually narrows from top to bottom. Since the lower end of the turbulence rib is closer to the crushing knife, the material at the lower end of the turbulence rib is generally well crushed. After such arrangement, the turbulence effect at the upper end of the turbulence rib is enhanced, which is beneficial to the concentration of the slurry and the material downward and to the middle, and then being brought up by the knife, and then being circulated and tumbled. That is, the material moves to the upper end and is blocked by the turbulence rib to quickly fall into the effective crushing area of the crushing knife, thereby improving the contact probability between the material and the crushing knife, and greatly improving the crushing effect and crushing effect of the material.

[0074] Secondly, in order to prevent the material and liquid from directly overflowing from the cup opening when hitting the turbulence rib, a certain distance C can be provided between the upper end of the turbulence rib 14 and the cup opening 11, and 20mm≤C≤30mm, C is specifically 25mm, that is, the upper end of the turbulence rib does not completely extend to the cup opening. In this way, when the material collides with the upper end of the turbulence rib, the material can fold back under the action of the turbulence rib, thereby well falling into the effective crushing area of the crushing knife. At the same time, a buffer space is provided for the continued upsurge of the liquid stream, which can prevent the material and liquid from overflowing from the cup opening during crushing or boiling, ensure that the liquid and material do not splash to the cup opening, and prevent the problem of splashing and injuring people. Not only does it improve the crushing efficiency and crushing effect of the material, but also ensures the safety of the food processor when pulping.

[0075] Finally, in order to facilitate the installation of the motor, the shell 2 can be provided with a housing 21 and a bottom cover 22 arranged at the bottom of the housing 21, the inner cup 1 is arranged in the housing 21, and the bottom of the inner cup 1 and the bottom cover 22 form an installation cavity 73, and the motor 4 is located in the installation cavity 73. The motor can be directly installed on the bottom of the inner cup, or can be installed on the bottom of the inner cup through a mounting bracket. The lower end of the motor abuts against the bottom cover 22. In this way, a separate motor base does not need to be arranged, and the installation cavity is formed between the bottom of the inner cup and the bottom cover for accommodating the motor, thereby greatly reducing the vertical size of the food processor as a whole, i.e., reducing the height of the food processor as a whole, so that the food processor is miniaturized and does not occupy space, and is easy to store. At the same time, the installation cavity is sufficient to ensure the heat dissipation effect of the motor, thereby ensuring the continuity and stability of the operation of the motor.

[0076] At the same time, the installation cavity 73 is also provided with a circuit board 10, and the circuit board 10 is annular and is sleeved on the outer periphery of the motor 4, i.e., the circuit board is arranged around the outer periphery of the motor, thereby greatly reducing the vertical installation height of the circuit board, thereby reducing the vertical height of the food processor as a whole, so that the food processor can be better miniaturized.

[0077] Moreover, the volume of the installation cavity 73 is V3, and the ratio of V3 to V is 1 / 4 to 1 / 2, and the ratio of V3 to V1 is 0.8 to 1.2. In the embodiment, the ratio of V3 to V is 1 / 3, and the ratio of V3 to V1 is 1. In this way, the size of the installation cavity is sufficient to install the motor and the circuit board, and the vertical height of the food processor as a whole is not additionally increased, thereby well achieving the miniaturization of the food processor, well accommodating the motor, and well ensuring the heat dissipation effect of the motor, thereby ensuring the stability and reliability of the operation of the motor, meeting the requirements of customers for the amount of pulp, and ensuring the rolling space of the material and the pulp during crushing, thereby achieving good pulp-making effect, safety, and easy cleaning.

[0078] Specifically, the vertical height of the installation cavity 73 is H1, and the vertical height of the food processor as a whole is H2, and the ratio of H1 to H2 is 1 / 4 to 1 / 2, and the ratio of H1 to H2 is 1 / 3. In this way, the vertical height of the installation cavity accounts for a reasonable proportion of the vertical height of the food processor as a whole, so that the size of the installation cavity is sufficient, thereby well accommodating the motor and well ensuring the heat dissipation effect of the motor, thereby ensuring the stability and reliability of the operation of the motor.

[0079] At the same time, the vertical height of the motor 4 is H3, and 50mm≤H3≤70mm, and H3 is specifically 60mm. Not only is the structure design of the motor facilitated to ensure the power of the motor and provide sufficient rotating power for the crushing knife to ensure the crushing effect, but also the vertical height of the motor is greatly reduced, thereby better achieving the miniaturization of the food processor and facilitating the installation of the motor in the installation cavity.

[0080] Moreover, the center of the bottom cover 22 is provided with an annular baffle 221 extending upward, and the upper end of the annular baffle 221 abuts against the lower end surface of the motor 4 after the bottom cover 22 is installed in place, so that the motor can be well fixed in position in the axial direction of the lower end, to ensure that the motor will not shake up and down during operation, thereby ensuring the stability of the motor during operation, and ensuring the stability of the food processor during operation.

[0081] Moreover, the bottom cover 22 is provided with a through hole within the annular baffle 221, and the lower end surface of the motor 4 is provided with a fixing hole, so that a fastener is connected through the through hole and the fixing hole to lock and fix the motor, and in this way, the motor is fixed by the fastener, better ensuring the reliability and stability of the motor fixation, thereby better ensuring the stability of the motor during operation, and better ensuring the stability of the food processor during operation.

[0087] It can be understood that C can also be 20mm, 21mm, 22mm, 23mm, 24mm, 26mm, 27mm, 28mm, 29mm, 30mm, etc.

[0090] It can be understood that the vertical height of the overflow port can also be 4mm, 5mm, 6mm, 8mm, 9mm, 10mm, etc.

[0091] It can be understood that E can be 8mm, 9mm, 10mm, 12mm, 13mm, 14mm, 15mm, etc.

[0092] It can be understood that V3 / V can also be 1 / 4, 3 / 10, 2 / 5, 1 / 2, etc.

[0094] It can be understood that H3 can also be 50mm, 55mm, 65mm, 70mm, etc.

[0095] Example Two:

[0096] The difference between this embodiment and Example One is that the structure of the cup cover is different.

[0097] In this embodiment, as shown in Figure 4 , the cup cover 6 is provided with a downwardly extending rim 61, and the longitudinal section of the cup cover 6 as a whole is in the shape of a T, that is, the lower end surface 64 of the cup cover 6 is at the same height as the inner top surface 65 of the cup cover 6, that is, on the same horizontal plane. This kind of cup cover can also achieve the beneficial effects in the above embodiments, and thus will not be described again.

[0098] The other parts of the structure and the beneficial effects thereof are the same as those of Example One, and thus will not be described again.

[0099] Example Three:

[0100] The difference between this embodiment and Examples One and Two is that the inner side wall of the rim is provided with a separation grid separating the overflow port into multiple windows.

[0101] In this embodiment, as shown in Figure 5 , the inner wall of the overflow port 612 is provided with a separation grid 63 separating the overflow port 612 into multiple windows, and the separation grid 63 extends downward from the inner top surface 65 of the cup cover 6 and extends through the overflow port 612 to the lower end of the rim. Since there is generally foam in the slurry, by setting the separation grid, when the slurry enters the overflow space through the overflow port or passes through the overflow port, the separation grid can play a role in defoaming the foam in the slurry, thereby better guaranteeing the anti-overflow effect of the food processor; at the same time, when the slurry is poured, the separation grid can also filter and block the dregs in the slurry, so as to improve the taste of the slurry.

[0102] And, the partition grid 63 is in a sheet shape and protrudes inwardly from the inner wall of the surrounding edge 61, and the protruding height is 4mm-8mm, specifically 6mm. In this way, the processing and forming of the partition grid are facilitated, and the defoaming effect of the partition grid is ensured.

[0103] It can be understood that the partition grid passing through the overflow port can also protrude into the inner wall of the overflow port, so that better defoaming can be achieved.

[0104] It can be understood that the protruding height can also be 4mm, 4.5mm, 5mm, 5.5mm, 6.5mm, 7mm, 7.5mm, 8mm, etc.

[0105] The structures and beneficial effects of other unstated parts are the same as those of Embodiments One and Two, and will not be repeated here.

[0106] Embodiment Four:

[0107] The difference between this embodiment and Embodiments One to Three is that the food processor is also provided with an anti-overflow electrode.

[0108] In this embodiment, as shown in Figure 6 the heating device 3 and the motor 4 are electrically connected with the circuit board 10, and the side wall of the inner cup 1 and located below the overflow port 612 is provided with an anti-overflow electrode 20, which is also connected with the circuit board 10. By arranging the anti-overflow electrode, the anti-overflow can be directly detected, that is, when the slurry rises and touches the anti-overflow electrode, the heating device reduces the power or stops working to reduce the heat in the inner cup, so as to avoid continuous heating to cause the slurry to overflow or spout, thereby improving the anti-overflow effect and accuracy of the food processor.

[0109] The structures and beneficial effects of other unstated parts are the same as those of Embodiments One to Three, and will not be repeated here.

[0110] Embodiment Five:

[0111] The difference between this embodiment and Embodiments One to Four is that the arrangement position of the circuit board is different.

[0112] In this embodiment, as shown in Figure 7 the circuit board 10 is arranged transversely and mounted on the bottom cover 22 by fasteners. In this way, the miniaturization of the food processor can also be well achieved, and the circuit board is stably mounted to ensure the stability and reliability of the circuit board during operation.

[0113] The structures and beneficial effects of other unstated parts are the same as those of Embodiments One to Four, and will not be repeated here.

[0114] Embodiment Six:

[0115] The difference between this embodiment and Embodiments One to Four is that the arrangement position of the circuit board is different.

[0116] In the embodiment, as shown in Figure 8 the circuit board 10 is arranged longitudinally in the mounting cavity 73 and below the motor 4, and around the inner side wall of the housing 21. In this way, the circuit board can not occupy a large space of the mounting cavity, and the vertical installation size of the circuit board is not additionally increased, so that the food processor can be better miniaturized.

[0117] The structures of other parts not described and their benefits are the same as those of Embodiments One to Four, which will not be described herein.

[0118] Embodiment Seven:

[0119] The difference between the embodiment and Embodiments One to Six is that the food processor is further provided with a heat insulation plate.

[0120] In the embodiment, as shown in Figures 9 to 12 the cup bottom of the inner cup 1 is provided with the heat insulation plate 8 covering the heating device 3, and the motor 4 is mounted on the heat insulation plate 8. The heat insulation plate is fixed on the cup bottom of the inner cup, which can well cover the heating device to avoid heat transfer from the heating device to the motor and the circuit board, and facilitate the installation of the motor.

[0121] Specifically, the central part of the heat insulation plate 8 is upwardly protruding to form an annular boss 81 with an annular inner cavity, the upper end of the motor 4 is arranged in the annular inner cavity, and the fastener passes through the upper surface of the annular boss 81 to be connected with the motor 4 to lock and fix the motor 4 and the heat insulation plate 8. In this way, the motor can be well fixed in the radial direction by the annular boss, and the motor and the heat insulation plate can be fixed by the fastener. The fastening mode is not only simple, but also reliable and not easy to loosen, so as to ensure the stability and reliability of the motor during operation.

[0122] Further, the heat insulation plate 8 is provided with an annular groove 82 around the annular boss 81. After the heat insulation plate 8 and the inner cup 1 are installed in place, the annular groove 82 covers the heating tube 31. In this way, the annular groove can better cooperate with the heating tube to completely cover the heating tube, which can well prevent heat loss and avoid heat transfer to the motor to ensure the normal operation of the motor and prevent the motor from being overheated to affect the service life.

[0123] In addition, the center of the bottom cover 22 is provided with an annular fence 221 extending upward. After the bottom cover 22 is installed in place, the upper end of the annular fence 221 abuts against the lower end surface of the motor 4. In this way, the motor can be well fixed in the axial direction to ensure that the motor does not shake up and down during operation, thereby ensuring the stability of the motor during operation and the stability of the food processor during operation.

[0124] Furthermore, the bottom cover 22 is provided with a through hole 222 located inside the annular surrounding plate 221, and the lower end face of the motor 4 is provided with a fixing hole. In this way, the fastener passes through the through hole and connects with the fixing hole to lock and fix the motor. With this setting, the motor is fixed to the bottom cover by the fastener, which better ensures the reliability and stability of the motor fixation, thereby better ensuring the stability of the motor when it is working, and thus better ensuring the stability of the food processing machine when it is working.

[0125] The other undescribed parts of the structure and beneficial effects are the same as those in Examples 1 to 6, and will not be described in detail here.

[0126] Example 8:

[0127] The difference between this embodiment and embodiment seven is that an insulating dustproof partition is provided between the outer periphery of the motor and the inner ring of the circuit board.

[0128] In this embodiment, as Figure 13 As shown, an insulating dustproof partition 9 is provided between the outer periphery of the motor 4 and the inner ring of the circuit board 10. By setting the insulating dustproof partition, the dust generated during the operation of the motor can be effectively prevented from entering the circuit board, so as to avoid the circuit board from malfunctioning due to dust ingress, thereby ensuring the working stability and reliability of the circuit board.

[0129] The other undescribed parts of the structure and their beneficial effects are the same as in Example 7, and will not be described in detail here.
