Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of life electric appliances, and particularly relates to a food processing machine with stable operation. BACKGROUND

[0002] The existing food processing machines such as meat grinders, dough mixers and the like usually comprise a cup body with a built-in stirring element and a main machine detachably connected with the cup body, the main machine is provided with a motor in it which is in transmission connection with the stirring element, and when the user uses the food processing machine to process food materials, the food materials are placed in the cup body, and the stirring element rotates under the driving of the motor to realize the processing of the food materials. However, the existing food processing machines have single functions and can only realize the processing of one kind or similar food materials, in order to realize the processing of different food materials, the user needs to purchase different types of food processing machines, such as when needing to grind meat, a meat grinder needs to be purchased to realize it; when needing to mix dough, a dough mixer needs to be purchased to realize it, the use cost is high, and different food processing machines need to be stored separately, which is not good for the user experience.

[0003] In order to solve the above problems, a food processing machine is disclosed in Chinese utility model patent CN212591738U, which is equipped with multiple stirring barrels, and when the user processes different food materials, different stirring barrels can be replaced to realize the processing of different food materials, which is more convenient to operate. At the same time, in order to save packaging and storage space, the multiple stirring barrels are stacked and buckled together, but when the user needs to process food materials, the stirring barrels need to be separated to process the food materials, which is very inconvenient to operate. In addition, in order to realize the positioning of the bottom wall of each stirring barrel and the stirring element, the bottom wall of each stirring barrel is provided with a positioning shaft which is in plug-in cooperation with the cutter shaft of the stirring element, and the positioning shaft is generally a metal part, which has high strength and good positioning effect on the cutter shaft, resulting in a large increase in the production cost of the stirring barrels. At the same time, in order to avoid the abutment of the positioning columns of the stacked stirring barrels and the bottom wall of the upper stirring barrel, a step part is arranged between the adjacent stirring barrels to realize limiting, so that the distance between the bottom walls of the two stirring barrels is far, and the height of the stacked stirring barrels is high, which is not convenient for the user to store. In addition, if the food materials are processed after being stacked, the height of the whole machine is high, so that the height of the center of gravity of the whole machine is high, and therefore, when the food materials collide with the cup wall during processing, the whole machine will vibrate and make noise, and even shake and fall, which seriously affects the user experience. SUMMARY

[0004] The utility model aims at providing a food processing machine with stable operation, which solves the problem of high center of gravity of the whole machine caused by the high stacking height of the multiple stirring barrels with positioning shafts in the existing food processing machine, and the problem of vibration and noise during food material processing.

[0005] To achieve the above object, the utility model provides a food processor with stable work, including the cup body of built -in stirring part and with cup body detachable connection's host computer, be equipped with motor in the host computer with stirring part transmission connection, the cup body includes the outer cup and the inner cup of detachable embedding in the outer cup, the outer cup bottom is equipped with with the blade shaft of stirring part plug -in cooperation's plug -in part, the inner cup bottom is equipped with with the cooperation part of plug -in part adaptation, and the distance between the outer bottom wall of inner cup and the inner bottom wall of outer cup is less than the height of plug -in part.

[0006] The cup body is provided with an outer cup and an inner cup detachably nested in the outer cup, so that the user can select different suitable inner cups or outer cups according to the food material processed by himself when using the food processor, realize the processing of the corresponding food material, meet the processing of different food materials, one machine with multiple functions, and improve the user experience. Meanwhile, the outer cup bottom is provided with a plug-in part for plug-in cooperation with the blade shaft of the stirring part, and the inner cup bottom is provided with a cooperation part adapted to the plug-in part, so that after the user nests the inner cup in the outer cup, the plug-in part can realize plug-in cooperation with the blade shaft, thereby realizing the positioning of the stirring part, ensuring the stability of the stirring part during rotation, and without the need to separate the inner cup and the outer cup, the food material can be processed, and the operation is more convenient and fast. Compared with the existing positioning column arranged on the inner cup and the outer cup bottom wall to realize the positioning of the blade shaft, the structure of the inner cup is greatly simplified, and different stirring parts can share one plug-in part for positioning, improving the standardization of the positioning structure of multiple stirring parts, and helping to reduce the production cost. The plug-in part is plug-in cooperated with the blade shaft, which can greatly shorten the distance between the inner cup bottom wall and the outer cup bottom wall, and the distance between the outer bottom wall of the inner cup and the inner bottom wall of the outer cup is less than the height of the plug-in part, so that the inner cup can be completely nested in the outer cup. Compared with the existing way of arranging a step on the outer cup to realize the support of the inner cup, which results in a large distance between the inner cup bottom wall and the outer cup bottom wall and a high axial height of the entire cup body, the height of the cup body after the inner cup is nested in the outer cup can be greatly reduced, thereby reducing the height of the center of gravity of the cup body. On the one hand, when the user processes food material, even if multiple cup bodies are stacked together, the food material can be processed at a relatively low center of gravity, making the work of the entire machine more stable, effectively avoiding the situation that the high center of gravity of the entire machine causes large vibration noise or even shaking and tilting during food material processing, and improving the stability of food material processing. On the other hand, when the user nests the inner cup in the outer cup for storage, the height of the entire machine is reduced, the storage space is reduced, and the user can store the entire machine more conveniently, improving the user experience. In addition, multiple cup bodies are stacked together for work, a noise reduction layer is formed between the outer cup and the inner cup, and the noise generated during the processing of the food material in the inner cup can be greatly attenuated in the noise reduction layer, thereby further improving the noise reduction effect.

[0007] In a preferred implementation of the food processor with stable operation, the insertion part is a first positioning column arranged on the inner bottom wall of the outer cup and extending upward, and the matching part is a through hole arranged on the bottom wall of the inner cup for the first positioning column to pass through.

[0008] By arranging the insertion part as a first positioning column arranged on the inner bottom wall of the outer cup and extending upward, and the matching part as a through hole arranged on the bottom wall of the inner cup for the first positioning column to pass through, after the inner cup is nested in the outer cup, the first positioning column can pass through the through hole to realize the insertion and matching with the knife shaft, ensuring the positioning effect of the first positioning column on the knife shaft, and the through hole and the first positioning column can also realize the radial limiting, thereby further improving the radial limiting effect of the outer cup on the inner cup, which can not only improve the coaxiality of the inner cup and the outer cup, thereby ensuring the stability of food processing, but also ensure the stability of the matching of the inner cup and the outer cup during food processing, avoiding the situation that the inner cup relatively moves radially to cause the collision noise between the inner cup and the outer cup due to the large gap between the inner cup and the outer cup during processing. In addition, the matching hole of the stirring member and the first positioning column is standardized, which is more convenient for the design and manufacture of the stirring member, helps to reduce the production cost, and the inner cup is provided with the positioning column, which effectively avoids the situation that the cleaning dead angle between the positioning column and the inner bottom wall of the inner cup causes difficult cleaning, and is more convenient for the user to clean the inner cup.

[0009] In a preferred implementation of the food processor with stable operation, a sealing element is further arranged between the through hole and the first positioning column, and the sealing element is provided with an avoiding hole for the first positioning column to pass through.

[0010] By further arranging a sealing element between the through hole and the first positioning column, and the sealing element is provided with an avoiding hole for the first positioning column to pass through, after the user nests the inner cup in the outer cup, the first positioning column can realize the sealing matching with the through hole through the sealing element, thereby avoiding the situation that the food in the inner cup flows into the outer cup through the gap between the first positioning column and the through hole during food processing, and ensuring the sealing performance of the inner cup during food processing.

[0011] In a preferred implementation of the food processor with stable operation, the avoiding hole is provided with an elastic sealing part, which can be opened and sealed with the outer side wall of the first positioning column under the abutting effect of the first positioning column.

[0012] By arranging the avoiding hole with an elastic sealing part, when the user nests the inner cup in the outer cup, the elastic sealing part can be opened and sealed with the outer side wall of the first positioning column under the abutting effect of the first positioning column, which not only ensures the passing of the first positioning column through the avoiding hole, but also realizes the sealing of the avoiding hole and the first positioning column, thereby further ensuring the sealing performance of the inner cup. In addition, when the user separates the inner cup from the outer cup after completing the food processing, the elastic sealing part can be reset under the elastic force to realize the sealing of the avoiding hole, thereby avoiding the situation that the food in the inner cup spills out through the avoiding hole, and improving the user experience.

[0013] In a preferred implementation of the food processor with stable operation, the matching part is a first recessed groove protruding upward from the inner cup bottom wall, the inserting part is a second positioning column arranged on the inner bottom wall of the outer cup and extending upward, the second positioning column extends into the first recessed groove, and the inner bottom wall of the inner cup extends into the knife shaft through the protrusion formed by the recessed groove.

[0014] By setting the matching part as a first recessed groove protruding upward from the inner cup bottom wall and the inserting part as a second positioning column arranged on the inner bottom wall of the outer cup and extending upward, after the inner cup is nested into the outer cup, the inner cup and the outer cup can be positioned through the insertion and matching of the first recessed groove and the second positioning column, realizing the radial limitation of the outer cup on the inner cup, and further improving the radial limitation of the outer cup on the inner cup. This can not only improve the coaxiality of the inner cup and the outer cup, thereby ensuring the stability of food processing, but also ensure the stability of the matching of the inner cup and the outer cup during food processing, avoiding the situation that the inner cup collides with the outer cup and generates noise due to the radial displacement of the inner cup relative to the outer cup caused by the large gap between the inner cup and the outer cup. Compared with the method of arranging a through hole in the inner cup, the inner cup can be fully closed, thereby eliminating the situation that food overflows from the through hole to the outer cup. Meanwhile, the inner bottom wall of the inner cup extends into the knife shaft through the protrusion formed by the recessed groove, realizing the dual-purpose of the recessed groove, so that the recessed groove can not only match the outer cup, but also position the knife shaft through the formed protrusion. The structure is simplified, and another structure component is not needed to position the knife shaft, thereby further reducing the production cost.

[0015] In a preferred implementation of the food processor with stable operation, the inserting part is a mounting groove sunk on the inner bottom wall of the outer cup, and the matching part is a convex shaft protruding downward from the outer bottom wall of the inner cup, which is inserted into the mounting groove.

[0016] By setting the inserting part as a mounting groove sunk on the inner bottom wall of the outer cup, the problem that the inserting hole of the stirring part is difficult to clean and prone to peculiar smell in the prior art is solved. The matching part is a convex shaft protruding downward from the outer bottom wall of the inner cup, which is inserted into the mounting groove. After the inner cup is nested into the outer cup, the inner cup and the outer cup can be positioned through the matching of the convex shaft and the mounting groove, realizing the radial limitation of the outer cup on the inner cup, and further improving the radial limitation of the outer cup on the inner cup. This can not only improve the coaxiality of the inner cup and the outer cup, thereby ensuring the stability of food processing, but also ensure the stability of the matching of the inner cup and the outer cup during food processing, avoiding the situation that the inner cup collides with the outer cup and generates noise due to the radial displacement of the inner cup relative to the outer cup caused by the large gap between the inner cup and the outer cup.

[0037] As Figures 1 to 8 ​As shown, the utility model provides a kind of food processing machine of stable work, including the cup body of built-in stirring member 5 and the host computer 1 of detachable connection with cup body, motor 2 is equipped in host computer 1, and stirring member 5 is drivingly connected, cup body includes outer cup 3 and the inner cup 4 of detachable nesting in outer cup 3, outer cup 3 bottom is equipped with the plug-in portion of the knife shaft 51 plug-in cooperation with stirring member 5, it needs to be explained, the plug-in portion and the plug-in cooperation of knife shaft 51 are not only limited to direct contact plug-in cooperation, it can also be indirect, such as the plug-in cooperation of other structures between two, here not specific limit, while inner cup 4 bottom is equipped with the matching portion of adaptation with plug-in portion, and the distance between the outer bottom wall of inner cup 4 and the inner bottom wall of outer cup 3 is less than the height of plug-in portion.

[0038] The cup body is provided with the outer cup 3 and the inner cup 4 which is detachably nested in the outer cup 3, so that the user can select different suitable inner cups 4 or outer cups 3 according to the food material processed by himself when using the food processor, realize the processing of the corresponding food material, meet the processing of different food materials, one machine with multiple uses, and improve the user experience. Meanwhile, the bottom of the outer cup 3 is provided with a plug-in part which is plugged with the shaft 51 of the stirring part 5, and the bottom of the inner cup 4 is provided with a matching part which is matched with the plug-in part, so that after the user nests the inner cup 4 in the outer cup 3, the plug-in part can realize the plug-in cooperation with the shaft 51, thereby realizing the positioning of the stirring part 5, ensuring the stability of the stirring part 5 when rotating, and without the need of disassembling the inner cup 4 and the outer cup 3, the food material can be processed, and the operation is more convenient and fast. Compared with the existing positioning column arranged on the bottom wall of the inner cup 4 and the outer cup 3 to realize the positioning of the shaft 51, the structure of the inner cup 4 is greatly simplified, at the same time, different stirring parts 5 can share one plug-in part to realize the positioning, improve the standardization of the positioning structure of multiple stirring parts 5, and help to reduce the production cost. The plug-in part is plugged with the shaft 51, which can greatly shorten the distance between the bottom wall of the inner cup 4 and the bottom wall of the outer cup 3, and the distance between the outer bottom wall of the inner cup 4 and the inner bottom wall of the outer cup 3 is less than the height of the plug-in part, so that the inner cup 4 can be completely nested in the outer cup 3. Compared with the existing way of arranging a step on the outer cup 3 to realize the support of the inner cup 4, which results in a large distance between the bottom wall of the inner cup 4 and the bottom wall of the outer cup 3 and a high axial height of the whole cup body, the height of the cup body after the inner cup 4 is nested in the outer cup 3 can be greatly reduced, thereby reducing the height of the center of gravity of the cup body. On the one hand, when the user processes the food material, even if multiple cup bodies are stacked together, the food material can be processed at a relatively low center of gravity, which makes the whole machine work more stably, effectively avoids the situation that the high center of gravity of the whole machine causes large vibration noise or even shaking and tilting during the processing of the food material, and improves the stability of the processing of the food material. On the other hand, when the user nests the inner cup 4 in the outer cup 3 to realize the storage, the height of the whole machine is reduced, the storage space is reduced, which is more convenient for the user to store the whole machine, and improves the user experience. In addition, multiple cup bodies are stacked together to work, a noise reduction layer is formed between the outer cup 3 and the inner cup 4, and the noise generated by the food material in the inner cup can be greatly attenuated in the noise reduction layer, thereby further improving the noise reduction effect.

[0039] It should be noted that the structure of the plug-in part and the matching part is not limited in the present application, which can be any one of the following embodiments:

[0040] Embodiment 1: as shown in Figure 1 , Figure 2 , in this embodiment, the plug-in part is a first positioning column 31 arranged on the inner bottom wall of the outer cup 3 and extending upward, and the matching part is a through hole 41 arranged on the bottom wall of the inner cup 4 for the first positioning column 31 to pass through.

[0041] By setting the plug-in part as the first positioning column 31 arranged on the bottom wall of the outer cup 3 and extending upward, and setting the matching part as the through hole 41 arranged on the bottom wall of the inner cup 4 for the first positioning column 31 to pass through, after the inner cup 4 is nested into the outer cup 3, the first positioning column 31 can pass through the through hole 41 to realize the plug-in matching with the cutter shaft 51, so as to ensure the positioning effect of the first positioning column 31 on the cutter shaft 51, and the through hole 41 and the first positioning column 31 can also realize the radial limiting, thereby further improving the radial limiting effect of the outer cup 3 on the inner cup 4, which can not only improve the coaxiality of the inner cup 4 and the outer cup 3, thereby ensuring the stability of food processing, but also can ensure the stability of the cooperation between the inner cup 4 and the outer cup 3 during food processing, thereby avoiding the situation that the inner cup 4 relatively moves radially relative to the outer cup 3 to cause the collision noise between the inner cup 4 and the outer cup 3 due to the large gap between the inner cup 4 and the outer cup 3. In addition, the cooperation hole of the stirring piece 5 and the first positioning column 31 is standardized, which is more convenient for the design and manufacture of the stirring piece, and is helpful to reduce the production cost, and the inner cup 4 is provided with the positioning column, which can effectively avoid the situation that the cleaning dead angle between the positioning column and the inner bottom wall of the inner cup 4 causes the difficulty in cleaning, and is more convenient for the user to clean the inner cup.

[0042] It should be noted that the forming of the first positioning column 31 is not specifically limited in the present application. For example, when the outer cup 3 is a glass cup, the first positioning column 31 can be integrally formed with the outer cup 3, or the first positioning column 31 can be a metal piece and be fixedly connected with the outer cup 3 through a fastener, which will not be described herein.

[0043] As a preferred embodiment under the present embodiment, as shown in Figure 2 , the through hole 41 and the first positioning column 31 are further provided with a sealing piece 6, the sealing piece 6 is provided with an avoiding hole 61 for the first positioning column 31 to pass through, and preferably, the hole wall of the avoiding hole 61 is in sealing abutment with the side wall of the first positioning column 31.

[0044] By further providing the sealing piece 6 between the through hole 41 and the first positioning column 31, and the avoiding hole 61 for the first positioning column 31 to pass through is arranged on the sealing piece 6, after the user nests the inner cup 4 into the outer cup 3, when the user adds flour and water into the inner cup 4, or processes the food with high moisture content after cooking, the first positioning column 31 can realize the sealing cooperation with the through hole 41 through the sealing piece 6, thereby avoiding the food in the inner cup 4 from flowing into the outer cup 3 through the gap between the first positioning column 31 and the through hole 41 during food processing, and ensuring the sealing performance of the inner cup 4 during food processing.

[0045] Further, as shown in Figure 3 , Figure 4As shown, the avoidance hole 61 is provided with an elastic sealing portion 62, which can be opened under the abutting action of the first positioning column 31 and abut and seal with the outer side wall of the first positioning column 31. Specifically, the top wall of the sealing member 6 is provided with a cross-shaped slot, so as to separate the top wall of the sealing member 6 into four elastic pieces, which are the elastic sealing portion 62.

[0046] By providing the avoidance hole 61 with the elastic sealing portion 62, when the user nests the inner cup 4 into the outer cup 3, the elastic sealing portion 62 can be opened under the abutting action of the first positioning column 31 and abut and seal with the outer side wall of the first positioning column 31, which not only ensures that the first positioning column 31 passes through the avoidance hole 61, but also realizes the sealing of the avoidance hole 61 and the first positioning column 31, further ensuring the sealing of the inner cup 4. After the user finishes processing the food material, the inner cup 4 is separated from the outer cup 3, and the elastic sealing portion 62 can be reset under the elastic force to realize the plugging of the avoidance hole 61, so as to avoid the food material in the inner cup 4 from overflowing outwards through the avoidance hole 61, and improve the user experience.

[0047] In this embodiment, the cooperating portion is a first recessed groove upwardly protruding from the bottom wall of the inner cup 4, and the insertion portion is a second positioning column provided on the inner bottom wall of the outer cup 3 and extending upwardly, the second positioning column extends into the first recessed groove, and the protrusion formed by the recessed groove of the inner bottom wall of the inner cup 4 extends into the knife shaft 51. Specifically, in this embodiment, the inner cup 4 can be a metal cup body, the first recessed groove can be formed by upward stamping, and a positioning groove for the protrusion is provided at the bottom of the knife shaft 51 to realize the insertion cooperation.

[0048] By setting the cooperating portion as a first recessed groove upwardly protruding from the bottom wall of the inner cup 4, and the insertion portion as a second positioning column provided on the inner bottom wall of the outer cup 3 and extending upwardly, after the inner cup 4 is nested into the outer cup 3, the inner cup 4 and the outer cup 3 can be positioned by the insertion cooperation of the first recessed groove and the second positioning column, realizing the radial limitation of the outer cup 3 on the inner cup 4, and further improving the radial limitation of the outer cup 3 on the inner cup 4. Not only can it improve the coaxiality of the inner cup 4 and the outer cup 3, thereby ensuring the stability of food material processing, but also can ensure the stability of the cooperation between the inner cup 4 and the outer cup 3 during food material processing, avoiding the situation that the inner cup 4 relatively moves radially relative to the outer cup 3 during processing to cause the collision noise between the inner cup 4 and the outer cup 3. Compared with the way of providing a through hole in the inner cup 4, the inner cup 4 can be fully closed, thereby eliminating the situation that the food material flows out to the outer cup through the through hole. At the same time, the protrusion formed by the recessed groove of the inner bottom wall of the inner cup 4 extends into the knife shaft 51, realizing the dual-purpose of the recessed groove, so that the recessed groove can not only cooperate with the outer cup 3, but also position the knife shaft 51 through the formed protrusion, which simplifies the structure and saves the structure component for positioning the knife shaft 51, thereby further reducing the production cost.

[0049] Embodiment 3: as shown in Figure 7 , Figure 8 In this embodiment, the insertion part is a mounting groove 34 provided in the inner bottom wall of the outer cup 3, and the matching part is a protruding shaft 44 protruding downward on the outer bottom wall of the inner cup 4, which is inserted into the mounting groove 34.

[0050] By setting the insertion part as the mounting groove 34 provided in the inner bottom wall of the outer cup 3, the problem that the insertion hole of the stirring part 5 is difficult to clean and prone to odor is solved. The matching part is the protruding shaft 44 protruding downward on the outer bottom wall of the inner cup 4, which is inserted into the mounting groove 34, so that after the inner cup 4 is nested into the outer cup 3, the inner cup 4 and the outer cup 3 can be limited in the radial direction of the outer cup 3 by the cooperation of the protruding shaft 44 and the mounting groove 34, thereby further improving the radial limiting effect of the outer cup 3 on the inner cup 4, which not only improves the coaxiality of the inner cup 4 and the outer cup 3, thereby ensuring the stability of food processing, but also ensures the stability of the cooperation between the inner cup 4 and the outer cup 3 during food processing, avoiding the situation that the inner cup 4 is displaced in the radial direction relative to the outer cup 3 during processing, causing the inner cup 4 and the outer cup 3 to collide and produce noise.

[0051] It should be noted that the positioning of the knife shaft 51 in this embodiment is not limited, which can be any one of the following embodiments:

[0052] Embodiment 1: as shown in Figure 8 In this embodiment, the inner bottom wall of the inner cup 4 is provided with a second sunken groove 45, and the second sunken groove 45 is provided in the protruding shaft 44, and the knife shaft 51 is provided with a rotating shaft 52 matched with the second sunken groove 45. Specifically, the inner cup 4 is made of metal material, and the second sunken groove 45 is formed by stamping the bottom wall of the inner cup 4 downward. It should be further noted that the forming of the rotating shaft 52 is not limited, which can be integrally formed with the knife shaft 51, or can be a separate part and fixed as a whole with the knife shaft 51 by gluing and the like, which will not be described here.

[0053] By setting the inner bottom wall of the inner cup 4 with a second sunken groove 45, and the second sunken groove 45 is provided in the protruding shaft 44, and the knife shaft 51 is provided with a rotating shaft 52 matched with the second sunken groove 45, so that the protruding shaft 44 can not only realize the cooperation with the outer cup 3, but also realize the positioning of the knife shaft 51 through the formed second sunken groove 45, the structure is more simplified, and another structure part is saved to realize the positioning of the knife shaft 51, further reducing the production cost.
