Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine with a stable structure. Background Art

[0002] Existing food processing machines such as grinders usually include a main machine with a motor, a material container disposed above the main machine, and a grinding assembly disposed in the material container. The grinding assembly includes a static grinding head and a dynamic grinding head disposed inside the static grinding head. When the user uses the food processing machine to process food, the food is placed in the material container, and the food is processed by the relative grinding of the dynamic grinding head and the static grinding head. However, since there is no limit structure on the top of the dynamic grinding head, it causes the material to be accumulated between the dynamic grinding head and the static grinding head when it rotates, resulting in the situation that the food cannot be processed further. In order to solve the above problems, as disclosed in Chinese invention patent CN202010431085.4, a bean grinding mechanism and a bean grinding device are provided, which include a bean grinding body with an inner grinder and an outer grinder, and the outer grinder sleeve is disposed outside the inner grinder. The grinding head body includes a first support frame and a second support frame, and a plurality of first extension arms for limiting the rotation axis of the dynamic grinding head are provided on the first support frame to limit the dynamic grinding head and ensure the smooth processing of food. However, in order to realize material storage and feeding, the above structure also needs to set up a bean grinding hopper, that is, a grinding head body needs to be set to realize the installation and limiting of the grinding head and the static grinding head, and a bean grinding hopper needs to be set to realize material storage and feeding. This causes the size of the whole machine to be too large, occupying a large space, and the axial dimension chain of the whole machine is long, resulting in low coaxiality of various components, thereby reducing the grinding accuracy of the dynamic grinding head and the static grinding head, seriously affecting the consumer experience. Utility Model Content

[0003] The utility model aims to provide a food processing machine with a stable structure, so as to solve the problem that in the existing food processing machine, a grinding head body needs to be provided to realize the installation and limiting of the grinding head and the static grinding head, resulting in a complex structure of the whole machine and a long axial dimension chain resulting in low coaxiality of the whole machine.

[0004] To achieve the above-mentioned purpose, the utility model provides a food processing machine with a stable structure, comprising a main machine with a motor, a material holding container arranged above the main machine and a grinding assembly arranged in the material holding container, the grinding assembly comprising a static grinding head and a dynamic grinding head arranged inside the static grinding head, the material holding container comprising a powder outlet bin and a material bin arranged above the powder outlet bin, the static grinding head is fixedly arranged on the inner side of the material bin, the dynamic grinding head is provided with a transmission shaft assembly connected to the output shaft of the motor, the transmission shaft assembly comprises a first shaft body extending from the top of the automatic grinding head, and a second shaft body located at the bottom of the dynamic grinding head and extending from the avoidance opening of the powder outlet bin and cooperating with the output shaft transmission, the first shaft body and the second shaft body move synchronously, and the material bin is provided with a limiting member extending inward from the inner side wall of the material bin and limiting the top of the first shaft body.

[0005] In this application, a limiting member is provided on the inner wall of the bin, extending inward and limiting the top of the first shaft body. The first shaft body is limited by the limiting member, and the second shaft body is limited by the avoidance opening. Thus, the top and bottom of the moving grinding head are limited, which helps to improve the position stability of the moving grinding head, ensure its stable rotation, and prevent the situation that the top of the moving grinding head is not limited, resulting in yaw and jamming during rotation, causing materials to accumulate between the moving grinding head and the static grinding head and preventing the continuous processing of food materials. This ensures the smooth progress of food material processing and improves the user experience. At the same time, compared with the traditional method that requires setting up a grinding head body to install the moving grinding head and the static grinding head and form the support ribs, this application eliminates the need to set up a separate grinding bean body. Only through the bin can storage and feeding of materials be realized, and at the same time, the support and limitation of the moving grinding head can be achieved, making the overall structure of the machine more compact and helping to reduce its occupied space. At the same time, when assembling the whole machine, compared with the prior art, the grinding bean body between the bin and the flour outlet bin is eliminated, thereby shortening the length of the axial dimension chain of the whole machine assembly, improving the installation accuracy, ensuring the coaxiality of the moving grinding head and the static grinding head, and helping to improve the grinding accuracy.

[0006] In a preferred implementation manner of a food processor with a stable structure, the limiting member is provided with a limiting hole extending axially and limiting the top of the first shaft body.

[0007] By providing a limiting hole extending axially and limiting the top of the first shaft body on the limiting member, the first shaft body is limited in all directions in the radial direction through the limiting hole, thereby preventing the first shaft body from swinging in the radial direction, further enhancing the limiting effect on the moving grinding head, ensuring its position stability, and thus ensuring the smooth progress of food material processing.

[0008] In a preferred implementation manner of a food processor with a stable structure, a partition extending horizontally inward is provided on the inner wall of the limiting hole to divide the limiting hole into an upper groove body and a lower groove body. An upper bearing cooperating with the first shaft body is provided in the upper groove body, and a lower bearing or gasket cooperating with the first shaft body is provided in the lower groove body.

[0009] By respectively providing an upper bearing and a lower bearing or gasket cooperating with the first shaft body in the upper groove body and the lower groove body, and limiting the first shaft body through the upper bearing and the lower bearing, the limiting effect can be further enhanced. At the same time, the first shaft body can be separated from the limiting hole, thus greatly reducing the friction between the first shaft body and the limiting hole. This can not only reduce the noise generated during the friction between the two, but also prevent the wear of the first shaft body and the limiting hole, avoiding the reduction of the limiting effect of the limiting hole on the first shaft body after a long time and causing its yaw.

[0010] In a preferred implementation manner of a food processor with a stable structure, the bottom wall of the limiting member extends obliquely upward and inward.

[0011] By setting the bottom wall of the limiting member to extend obliquely upward and inward, a buffer cavity is formed below the limiting member. After the materials above the silo enter the buffer cavity, the inclined bottom wall of the limiting member will exert a certain downward pressure on the food materials in the buffer cavity, thereby ensuring that the food materials are pressed down into the grinding structure, ensuring the uniformity of food material grinding, improving the grinding efficiency at the same time, and shortening the processing time of the food materials.

[0012] In a preferred implementation manner of a food processor with stable structure, a plurality of limiting members are provided and arranged at intervals along the circumferential direction of the silo, and a feed inlet is formed between two adjacent limiting members; or,

[0013] The limiting member is a block structure with a fan-shaped cross section in the transverse direction, and a feed inlet is formed in the area outside the limiting member; or,

[0014] The limiting member includes a plate body extending along the axial direction and an annular limiting wall connected to the inner end of the plate body, and the inner side of the annular limiting wall limits the first shaft body.

[0015] By providing a plurality of limiting members and arranging them at intervals along the circumferential direction of the silo, and forming a feed inlet between two adjacent limiting members, the limiting members limit the first shaft body in multiple directions, further enhancing the limiting effect on the moving grinding head, ensuring its position stability, and improving the strength of the limiting members at the same time, avoiding the situation that the limiting members are bent or even broken when subjected to a large force, and ensuring its limiting effect.

[0016] By setting the limiting member as a block structure with a fan-shaped cross section in the transverse direction, and forming a feed inlet in the area outside the limiting member, the strength of the limiting member is greatly enhanced, thereby ensuring that it can withstand a greater acting force, avoiding the situation of being broken when subjected to a large force, and ensuring its limiting effect.

[0017] In a preferred implementation manner of a food processor with stable structure, a transmission groove with an opening facing downward is provided at the bottom of the second shaft body, the top of the output shaft extends into the transmission groove for transmission cooperation, and the output shaft is provided with a stepped portion with a stepped surface facing upward, and the bottom wall of the second shaft body abuts against the stepped surface.

[0018] By providing a transmission groove with an opening facing downward at the bottom of the second shaft body and the top of the output shaft extending into the transmission groove for transmission cooperation, the transmission cooperation between the motor and the second shaft body is realized. At the same time, the output shaft is provided with a stepped portion with a stepped surface facing upward, and the bottom wall of the second shaft body abuts against the stepped surface, so that the output shaft realizes the axial positioning of the second shaft body and the entire moving grinding head by means of the abutment between the stepped surface and the bottom wall of the second shaft body, ensuring its axial position reliability, avoiding the situation that the moving grinding head moves downward and causes friction and wear between the moving grinding head and the bottom wall of the powder outlet bin, and ensuring the grinding gap between the moving grinding head and the static grinding head at the same time, avoiding the situation that the grinding gap becomes too wide due to the downward movement of the moving grinding head, resulting in low grinding accuracy and poor taste.

[0019] In a preferred implementation of a food processor with stable structure, a slot is provided in the moving grinding head, the first shaft body is installed in the slot, and the grinding assembly further includes a connecting piece which passes through the top wall of the transmission slot and is fastened to the bottom of the first shaft body.

[0020] By passing the connecting piece through the top wall of the transmission slot and fastening it to the bottom of the first shaft body, the connection and cooperation between the moving grinding head and the first shaft body are realized by one connecting piece, the assembly is more convenient and fast, which helps to improve the assembly efficiency. At the same time, the coaxiality of the first shaft body and the second shaft body can be ensured, and the situation that the moving grinding head is stuck due to yaw during rotation, resulting in the accumulation of materials between the moving grinding head and the static grinding head and the inability to continue processing the food materials, is avoided, ensuring the smooth progress of food material processing and improving the user experience.

[0021] In a preferred implementation of a food processor with stable structure, the bottom wall of the flour outlet bin is provided with an enclosing wall extending towards the moving grinding head, an avoidance opening is formed inside the enclosing wall, and an inwardly extending annular rib is further provided inside the enclosing wall, and a limiting bearing cooperating with the second shaft body is provided above the annular rib.

[0022] By providing a limiting bearing cooperating with the second shaft body above the annular rib, the second shaft body can be separated from the avoidance opening, thus greatly reducing the friction force between the second shaft body and the avoidance opening. Not only can the noise generated during the friction between the two be reduced, but also the situation that the second shaft body and the avoidance opening are worn, resulting in the reduction of the limiting effect of the avoidance opening on the second shaft body and its yaw after a long time, can be avoided.

[0023] In a preferred implementation of a food processor with stable structure, a sealing member is provided between the avoidance opening and the second shaft body, and the sealing member extends upward to protrude from the top wall port of the avoidance opening and abuts against the bottom wall of the moving grinding head.

[0024] By providing a sealing member between the avoidance opening and the second shaft body, the situation that the food materials overflow outward through the gap between the avoidance opening and the second shaft body is effectively avoided. At the same time, the situation that the food materials enter the gap between the two, resulting in an increase in the frictional resistance and a large frictional noise, can be avoided, ensuring the smooth progress of food material processing. At the same time, the sealing member extends upward to protrude from the top wall port of the avoidance opening and abuts against the bottom wall of the moving grinding head, realizing the axial positioning of the moving grinding head and the separation of the moving grinding head from the top wall of the avoidance opening, avoiding the situation that the two are in direct contact and cause large friction and wear.

[0025] In a preferred implementation of a food processor with stable structure, the avoidance opening is provided with an inwardly extending limiting ring rib, and the outer wall of the sealing member is provided with a limiting ring groove adapted to the limiting ring rib.

[0026] By providing a limiting annular rib extending inwards at the avoidance opening and providing a limiting annular groove on the outer wall of the seal member that is adapted to the limiting annular rib, the fixation of the seal member is achieved, the reliability of the position of the seal member is improved, and the situation where the displacement of the seal member causes the limiting effect on the moving grinding head to deteriorate or even fail is avoided.

Detailed Embodiments

[0036] In order to more clearly illustrate the overall concept of the present utility model, the following will be described in detail by way of examples in combination with the accompanying drawings of the specification.

[0037] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0038] As Figures 1 to 6 shown, the present utility model provides a food processor with a stable structure, including a main body 1 with a motor 2 disposed therein, a material storage container disposed above the main body 1, and a grinding assembly disposed in the material storage container. The grinding assembly includes a stationary grinding head 6 and a rotating grinding head 5 disposed inside the stationary grinding head 6. The material storage container includes a flour outlet bin 4 and a material bin 3 disposed above the flour outlet bin 4. The stationary grinding head 6 is fixedly disposed inside the material bin 3. The rotating grinding head 5 is provided with a transmission shaft assembly drivingly connected to the output shaft 21 of the motor 2. The transmission shaft assembly includes a first shaft body 7 extending from the top end of the rotating grinding head 5, and a second shaft body 8 located at the bottom of the rotating grinding head 5 and extending out of an avoidance opening 41 of the flour outlet bin 4 and drivingly cooperating with the output shaft 21. The first shaft body 7 and the second shaft body 8 move synchronously. The material bin 3 is provided with a limiting member 31 extending inward from the inner side wall of the material bin 3 and limiting the top of the first shaft body 7.

[0039] In this application, by providing a limiting member 31 in the material bin 3 that extends inward from the inner side wall of the material bin 3 and limits the top of the first shaft body 7, the first shaft body 7 is limited by the limiting member 31, and the second shaft body 8 is limited by the avoidance opening 41, thereby realizing the limitation of the top and bottom of the rotating grinding head 5, which helps to improve the position stability of the rotating grinding head 5, ensure its stable rotation, and avoid the situation where the top of the rotating grinding head 5 is not limited, resulting in its yaw and jamming during rotation, causing the accumulation of materials between the rotating grinding head 5 and the stationary grinding head 6, and preventing the continuous processing of food materials, ensuring the smooth progress of food material processing, and improving the user experience. At the same time, compared with the traditional method that requires setting a grinding head body to realize the installation of the rotating grinding head 5 and the stationary grinding head 6 and the formation of support ribs, the separate setting of the grinding bean body is omitted. Only through the material bin 3 can the storage and feeding of materials be realized while also realizing the support and limitation of the rotating grinding head 5, thereby simplifying the structural components of the whole machine, making the whole machine structure more compact, and helping to reduce its occupied space. At the same time, when assembling the whole machine, compared with the prior art, the grinding bean body between the material bin 3 and the flour outlet bin 4 is omitted, thereby shortening the axial dimension chain length of the whole machine assembly, improving the installation accuracy, ensuring the coaxiality of the rotating grinding head 5 and the stationary grinding head 6, and helping to improve the grinding accuracy.

[0040] As a preferred embodiment of this application, as Figure 2 shown, the limiting member 31 is provided with a limiting hole 311 extending axially and limiting the top of the first shaft body 7.

[0041] By providing a limiting hole 311 that axially extends and limits the top of the first shaft body 7 on the limiting member 31, the first shaft body 7 can achieve all-round radial limiting through the limiting hole 311, thereby avoiding radial swing of the first shaft body 7, further enhancing the limiting effect on the moving grinding head 5, ensuring its position stability, and thus ensuring the smooth progress of food processing.

[0042] As a preference under this embodiment, as Figure 2 shown, a partition 3111 that extends horizontally inward is provided on the inner wall of the limiting hole 311 to divide the limiting hole 311 into an upper groove body and a lower groove body. An upper bearing 9 that cooperates with the first shaft body 7 is provided in the upper groove body, and a lower bearing 10 or a gasket that cooperates with the first shaft body 7 is provided in the lower groove body. Specifically, a through hole for the first shaft body 7 to pass through is further provided on the partition 3111.

[0043] By respectively providing an upper bearing 9 and a lower bearing 10 or a gasket that cooperate with the first shaft body 7 in the upper groove body and the lower groove body, and limiting the first shaft body 7 through the upper bearing 9 and the lower bearing 10, the limiting effect can be further enhanced, and at the same time, the first shaft body 7 can be separated from the limiting hole 311, thereby greatly reducing the friction force between the first shaft body 7 and the limiting hole 311. This can not only reduce the noise generated during the friction between the two, but also avoid the situation where the limiting hole 311 wears due to the friction with the first shaft body 7, resulting in a decrease in the limiting effect of the limiting hole 311 on the first shaft body 7 after a long time and causing it to deflect.

[0044] As a preferred embodiment of the present application, as Figure 2 、 Figure 3 shown, the bottom wall of the limiting member 31 extends obliquely upward and inward.

[0045] By setting the bottom wall of the limiting member 31 to extend obliquely upward and inward, a buffer cavity is formed below the limiting member 31. After the materials above the feed bin 3 enter the buffer cavity, the inclined bottom wall of the limiting member 31 will generate a certain downward pressure on the food materials in the buffer cavity, thereby ensuring that the food materials are pressed down into the grinding structure, ensuring the uniformity of food grinding, and at the same time improving the grinding efficiency and shortening the processing time of the food materials.

[0046] As a preferred embodiment of the present application, as Figure 5 shown, in this embodiment, a plurality of limiting members 31 are provided and are arranged at intervals along the circumferential direction of the feed bin 3. An inlet 104 is formed between two adjacent limiting members 31.

[0047] By providing a plurality of limiting members 31, which are arranged at intervals along the circumferential direction of the bin 3, a feed inlet 104 is formed between two adjacent limiting members 31, so that the limiting members 31 limit the first shaft body 7 in multiple directions, further enhancing the limiting effect on the moving grinding head 5, ensuring its position stability, and at the same time enhancing the strength of the limiting members 31, avoiding the situation that the limiting members 31 are bent or even broken when subjected to a large force, and ensuring their limiting effect.

[0048] It should be noted that the structure of the limiting member 31 is not specifically limited in this application, and it can be any one of the following embodiments:

[0049] Embodiment 1: As Figure 6 shown, in this embodiment, the limiting member 31 is a block structure with a fan-shaped cross-section in the transverse direction, and the area outside the limiting member 31 forms a feed inlet 104.

[0050] By setting the limiting member 31 as a block structure with a fan-shaped cross-section in the transverse direction, and the area outside the limiting member 31 forms a feed inlet 104, the strength of the limiting member 31 is greatly enhanced, thereby ensuring that it can withstand greater acting forces, avoiding the situation of breakage when the force is large, and ensuring its limiting effect.

[0051] Embodiment 2: As Figure 3 shown, in this embodiment, the limiting member 31 includes a plate body extending along the axial direction and an annular limiting wall connected to the inner end of the plate body, and the inner side of the annular limiting wall limits the first shaft body 7.

[0052] Preferably, one end of the plate body is connected to the inner wall of the bin 3, the other end is connected to the annular limiting wall, and the bottom wall of the plate body extends obliquely upward from the outside to the inside.

[0053] It should be noted that the transmission connection method between the second shaft body 8 and the output shaft 21 is not specifically limited in this application. As a preferred embodiment of this application, as Figure 2 shown, a transmission groove with an opening facing downward is provided at the bottom of the second shaft body 8, the top of the output shaft 21 extends into the transmission groove for transmission cooperation, and the output shaft 21 is provided with a stepped portion with a stepped surface facing upward, and the bottom wall of the second shaft body 8 abuts against the stepped surface.

[0054] By providing a transmission groove with an opening facing downward at the bottom of the second shaft body 8, and inserting the top of the output shaft 21 into the transmission groove for transmission cooperation, the transmission cooperation between the motor 2 and the second shaft body 8 is achieved. At the same time, the output shaft 21 is provided with a stepped portion with a stepped surface facing upward, and the bottom wall of the second shaft body 8 abuts against the stepped surface, so that the output shaft 21 realizes the axial positioning of the second shaft body 8 and the entire moving grinding head 5 by means of the abutment between the stepped surface and the bottom wall of the second shaft body 8, ensuring the reliability of its axial position, avoiding the situation that the moving grinding head 5 moves downward and causes friction and wear between the moving grinding head 5 and the bottom wall of the powder outlet bin 4, and at the same time ensuring the grinding gap between the moving grinding head 5 and the static grinding head 6, avoiding the situation that the downward movement of the moving grinding head 5 causes the grinding gap to be too wide, resulting in low grinding accuracy and poor taste.

[0055] Of course, it can also be that a coupling is provided at the bottom end of the second shaft body 8, and a coupling that is in transmission cooperation with the upper coupling is provided at the top end of the output shaft 21, and the two realize the transmission of torque through the coupling.

[0056] Furthermore, it should be noted that the present application does not specifically limit the relative relationship between the first shaft body 7 and the moving grinding head 5. It can be that the first shaft body 7 is integrally formed at the top end of the moving grinding head 5, or as a preferred embodiment of the present application, as Figure 2 shown, a slot is provided in the moving grinding head 5, the first shaft body 7 is installed in the slot, and the grinding assembly further includes a connecting member 102. The connecting member 102 passes through the top wall of the transmission groove and is fastened to the bottom of the first shaft body 7. Specifically, the connecting member 102 is a screw.

[0057] By passing the connecting member 102 through the top wall of the transmission groove and fastening it to the first shaft body 7, one connecting member 102 realizes the connection and cooperation between the moving grinding head 5 and the first shaft body 7, making the assembly more convenient and fast, helping to improve the assembly efficiency, and at the same time ensuring the coaxiality of the first shaft body 7 and the second shaft body 8, avoiding the situation that the moving grinding head 5 deflects and jams during rotation, resulting in the accumulation of materials between the moving grinding head 5 and the static grinding head 6, causing the food ingredients to be unable to continue processing, ensuring the smooth progress of food ingredient processing, and improving the user experience.

[0058] It should be noted that the present application does not specifically limit the positioning method of the second shaft body 8, and it can be any one of the following embodiments:

[0059] Embodiment 1: As Figure 4 shown, in this embodiment, the bottom wall of the powder outlet bin is provided with a surrounding wall extending towards the moving grinding head 5. An avoidance opening 41 is formed inside the surrounding wall, and an inwardly extending annular rib 412 is further provided inside the surrounding wall. A limit bearing 103 that cooperates with the second shaft body 8 is provided above the annular rib 412.

[0060] By providing a limiting bearing 103 that cooperates with the second shaft body 8 above the annular rib 412, the second shaft body 8 can be separated from the avoidance opening 41, thereby greatly reducing the friction between the second shaft body 8 and the avoidance opening 41. This not only reduces the noise generated by the friction between the two, but also prevents the second shaft body 8 and the avoidance opening 41 from being worn out, resulting in a reduction in the limiting effect of the avoidance opening 41 on the second shaft body 8 after a long time, causing it to swing.

[0061] Example 2: Figure 2 As shown, in this embodiment, a sealing member 101 is provided between the avoidance opening 41 and the second shaft body 8 , and the sealing member 101 extends upward to protrude from the top wall of the avoidance opening 41 and abuts against the bottom wall of the movable grinding head 5 .

[0062] By providing a seal 101 between the avoidance opening 41 and the second shaft body 8, it is effectively prevented that food overflows through the gap between the avoidance opening 41 and the second shaft body 8, and it is also prevented that food enters the gap between the two, causing the friction resistance to increase and generating a large friction noise, thereby ensuring the smooth processing of food. At the same time, the seal 101 extends upward to protrude from the top wall of the avoidance opening 41 and abuts against the bottom wall of the moving grinding head 5, thereby achieving axial positioning of the moving grinding head 5 and separation of the moving grinding head 5 from the top wall of the avoidance opening 41, thereby avoiding direct contact between the two, which may cause large friction and wear between the two.

[0063] Furthermore, if Figure 2 As shown, the avoidance opening 41 is provided with a limiting ring rib 411 extending inwardly, and the outer wall of the sealing member 101 is provided with a limiting ring groove 1011 adapted to the limiting ring rib 411 .

[0064] By providing a limiting ring rib 411 extending inwardly at the avoidance opening 41, and providing a limiting ring groove 1011 adapted to the limiting ring rib 411 on the outer wall of the sealing member 101, the sealing member 101 can be fixed, the reliability of the position of the sealing member 101 can be improved, and the situation in which the displacement of the sealing member 101 causing the limiting effect on the movable grinding head 5 to deteriorate or even fail can be avoided.

[0065] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to it based on the present utility model. Therefore, these modifications or improvements made without departing from the spirit of the present utility model are within the scope of protection claimed by the present utility model.
