[0050] As Figure 1 shown, the utility model provides a kind of food processor in an implementation, including host computer 10 and stirring cup 20, stirring cup 20 is provided with the stirring piece 21 of vertical arrangement, host computer 10 is provided with motor assembly 30, host computer 10 includes the bottom cover 101 supported below motor assembly 30, bottom cover 101 is provided with through hole, the output end of motor assembly 30 is exposed from through hole to be transmissionally connected with stirring piece 21, motor assembly 30 includes motor body 31, fixedly connected in the reduction gearbox 32 of motor body 31 lower end and fixed support 40, as Figure 2 shown, fixed support 40 includes the first support 41 fixed to the outer periphery of motor body 31, first support 41 is equipped with extension 411, extension 411 extends downward along the outer periphery of reduction gearbox 32 to be connected with bottom cover 101.

[0051] The food processor provided by this utility model, by setting a first bracket 41, is fixed to the outer periphery of the motor body 31, rather than placing the fixing bracket on the gear ring of the gearbox (which is close to the lower part of the motor assembly) as in the prior art. This improves the fixing position of the motor assembly, making it more centrally located. In addition, the fixed distance between this fixing position and the bottom cover is increased, which is equivalent to increasing the torque. This helps the first bracket 41 to provide a stable fixing effect on the motor body 31, thus significantly reducing the wobble of the tail end of the motor body 31. Furthermore, since the first bracket 41 is not set on the main unit housing, it does not interfere with the buttons or other structures on the main unit housing. By providing an extension 411 on the first bracket 41, the extension 411 extends downward along the outer periphery of the gearbox 32 to connect with the bottom cover 101. The extension 411 not only connects the motor body 31 and the bottom cover 101, but also provides radial restraint for the gearbox 32 along its outer periphery, further preventing the motor body 31 from swaying due to the gearbox 32's swaying, thus achieving a reliable connection between the motor assembly 30 and the bottom cover 101. The motor body 31 and the bottom cover 101 are fixed and have their sway limited only by the first bracket 41, resulting in a simple structure, low cost, and easy installation. In summary, this utility model, while simplifying the structure and assembly of the main unit 10, achieves a stable installation of the motor assembly 30, enables the main unit 10 to pass the drop test on the first attempt, avoids economic losses caused by the breakage of the main unit 10's casing, and ensures a reliable and durable connection between the motor assembly 30 and the bottom cover 101, reducing loosening of connections and abnormal operating noises caused by transportation, improving the user experience, and extending the overall service life of the machine.

[0052] It should be noted that this utility model does not limit the specific structure of the fixing bracket; for example, it can adopt any one of the following embodiments 1-3:

[0053] Implementation Example 1, such as Figures 1-7 As shown, the fixed bracket 40 includes a first bracket 41 and a second bracket 42, as referenced. Figure 3 and Figure 4 The second bracket 42 is disposed on the outside of the gearbox 32 and is fixedly connected to the extension 411. The gearbox 32 is axially clamped between the first bracket 41 and the second bracket 42. In this embodiment, the first bracket 41 and the second bracket 42 are separately disposed and both are connected to the bottom cover 101.

[0054] Of course, optionally, since the second bracket 42 and the extension 411 are fixedly connected, the first bracket can also be indirectly connected to the bottom cover through the second bracket.

[0055] The embodiment sets the second support 42 fixedly connected to the outer periphery of the reduction gearbox 32, and the second support 42 is fixedly connected to the extension part 411. The second support 42 has a direct force on the reduction gearbox 32, and indirectly provides an additional supporting force on the motor body 31. The motor assembly 30 is fixed on the basis of the first support 41, and the second support 42 is additionally positioned to improve the overall stability of the motor assembly 30, further reduce the possibility of the tail end of the motor body 31 to deviate, and the reduction gearbox 32 is axially clamped between the first support 41 and the second support 42. The reduction gearbox 32 is fixedly reliable, and the meshing degree between the internal gear and the gear ring of the reduction gearbox 32 is improved, and the transmission noise is small.

[0056] In the embodiment, the first support 41 and the second support 42 are separately arranged, the first support 41 is made of a material with high strength, and the second support 42 for auxiliary positioning can be made of a material with low cost. On the basis of realizing the effect of double positioning, the overall cost of the machine is reduced. Of course, the first support 41 and the second support 42 can be formed integrally, or the first support can be understood as integrating the detailed arrangement of the first support and the second support in the embodiment to avoid the trouble of assembling the first support and the second support.

[0057] More preferably, in combination with Figure 2 , 3 As shown, the extension part 411 includes a plurality of extension plates arranged at intervals along the outer periphery of the reduction gearbox 32, and the second support 42 includes a plurality of limiting plates 421 arranged at intervals around the outer periphery of the reduction gearbox 32. A single limiting plate 421 is inserted between two adjacent extension plates, so that the extension plates and the limiting plates 421 are arranged alternately.

[0058] For the first support 41, a plurality of extension plates are arranged at intervals along the outer periphery of the reduction gearbox 32. While realizing the circumferential multi-directional limiting and fixing of the reduction gearbox 32, unnecessary structural waste is avoided, and the material cost of the first support 41 is reduced. The second support 42 is provided with a plurality of limiting plates 421, a single limiting plate 421 is inserted between two adjacent extension plates, and the extension plates and the limiting plates 421 are arranged alternately.

[0059] Regarding the structure of the second support, preferably, as shown in Figure 3 The second support 42 is provided with a supporting plate 422 supported on the bottom end surface of the reduction gearbox 32, so that the reduction gearbox 32 is axially clamped between the first support 41 and the second support 42 by means of the supporting plate.

[0060] Of course, in other embodiments, the second support 41 can be sleeved on the bottom end of the reduction gearbox 32 to realize the axial reliable clamping of the first support and the second support on the reduction gearbox 32.

[0061] By setting the support plate 422 on the second support 42, the support plate 422 is supported on the bottom end face of the reduction box 32 to realize the axial support of the reduction box 32, avoid the bottom end of the reduction box 32 to be suspended, so that the fixing of the reduction box 32 is stable, and the bearing capacity of the first support 41 and the second support 42 is also dispersed, so that the stress concentration is avoided to cause the support to be broken.

[0062] It should be noted that the structure of the first support provided by the embodiment example is still applicable to other embodiment examples, that is, in a preferred embodiment, the extension parts 411 are arranged at intervals, and the heat dissipation holes for heat dissipation of the motor body are formed between the adjacent extension parts 411.

[0063] By setting the plurality of extension parts 411, the multi-directional limiting along the circumferential direction of the motor assembly 30 is provided, the motor assembly 30 is effectively avoided to be deflected, the heat dissipation holes are formed between the adjacent extension parts 411, so that the good heat dissipation of the motor body is realized, the temperature rise of the motor body is avoided to be too large, and the service life is prolonged; in addition, the heat dissipation holes are formed between the adjacent extension parts 411, which are also weight reduction holes, so that the self-weight of the first support 41 can be reduced, the weight of the entire main machine 10 can be reduced, and the main machine 10 is light and easy to take and place.

[0066] In addition, the specific connection mode of the fixed support and the motor body is not limited in the utility model, and any one of the following embodiment examples 4, 5 and 6 can be adopted:

[0067] Embodiment example 4, referring to Figure 1 , 3 , the motor body 31 includes an upper end cover 311, a lower end cover 312 and a stator 313 and a rotor 314 arranged between the upper end cover 311 and the lower end cover 312, and the reduction box 32 is fixedly connected to the lower end cover 312, as shown in Figure 3 , the first support 41 is integrally formed on the lower end cover 312.

[0068] Embodiment example 5, the difference between the embodiment example 5 and the embodiment example 4 is that the first support 41 is integrally formed on the upper end cover 311.

[0069] By integrally forming the first support 41 on the upper end cover 311 or the lower end cover 312, the number of parts of the motor body 31 is simplified, the assembly steps are saved, and the assembly efficiency is improved. At the same time, the first support 41 is integrally connected to the upper end cover 311 or the lower end cover 312, and the connection is reliable, avoiding the problem of falling off of the first support 41, and realizing reliable fixation of the motor assembly 30.

[0070] In the embodiment example 6, the motor body 31 comprises an upper end cover 311, a lower end cover 312, and a stator 313 and a rotor 314 arranged between the upper end cover 311 and the lower end cover 312, and the outer peripheral wall of the stator 313 has an exposed part exposed to the upper end cover 311 and the lower end cover 312, and the first support 41 is sleeved and fixed on the outer periphery of the exposed part.

[0071] By providing the outer peripheral wall of the stator 313 with the exposed part exposed to the upper end cover 311 and the lower end cover 312, the axial precision requirement between the upper end cover 311, the lower end cover 312 and the stator 313 can be reduced, and the assembly is labor-saving. The first support 41 is sleeved on the exposed part of the stator 313, so that the structure of the motor body 31 is compact, the space is reasonably utilized, and the upper end cover 311 and the lower end cover 312 can also play the effect of axial limiting of the first support 41.

[0072] In addition, it should be noted that the motor body in the above three embodiment examples can be a brushless motor or a brushed motor. The specific connection mode of the fixing support and the motor body in the embodiment examples 4-6 can be combined with any one of the fixing support structures in the embodiment examples 1-3.

[0073] It should be further noted that in the utility model, the connection between the first support and the bottom cover can be fixed connection, that is, the whole motor assembly is fixed in the main machine and cannot move; of course, the first support and the bottom cover can also be connected in a lifting manner, and the specific connection mode will be described in detail below in combination with the food processor form.

[0074] The utility model does not limit the whole machine form of the food processor, and in one embodiment, the food processor is a table type food processor with a support seat on the main machine, as shown in the embodiment example 1. Of course, in addition to the above table type food processor form, it can also be a main machine top-mounted food processor, as shown in the embodiment example 7, the main machine 10 is detachably mounted above the cup cover 22 of the stirring cup 20. Figure 8

[0075] Next, the lifting connection mode of the first support and the bottom cover will be described in detail in combination with the table type food processor form:

[0076] In the embodiment example 1, as shown in Figures 1-7 ​As shown, the main machine 10 comprises a support base 11 and a machine head 12 installed above the support base 11, an installation space for installing the stirring cup 20 is formed between the machine head 12 and the support base 11, the motor assembly 30 is arranged inside the machine head 12 and the bottom cover 101 is located at the bottom end of the machine head 12. As preferred, as shown in the accompanying drawings, Figure 2 As shown, the main machine 10 further comprises a rotating platform 60 rotatably installed above the bottom cover 101, a lifting mechanism 50 is arranged between the rotating platform 60 and the fixed support 40, the extension part 411 extends downward and is connected to the bottom cover 101 in a lifting manner, so that the rotating platform 60 rotates to drive the motor assembly 30 to lift relative to the bottom cover 101.

[0077] By arranging the main machine 10 as a table type main machine 10, i.e. comprising the support base 11 and the machine head 12, an installation space for installing the stirring cup 20 is formed between the machine head 12 and the support base 11, so that the user only needs to take the stirring cup 20 alone when using, without the need to move the heavy main machine 10, which is convenient, flexible and good in use experience. By arranging the rotating platform 60 and the lifting mechanism 50, the extension part 411 is connected to the bottom cover 101 in a lifting manner, so that the rotating platform 60 rotates to drive the motor assembly 30 to lift relative to the bottom cover 101. For the table type main machine 10, since the main machine 10 is placed on the workbench and the user does not move the main machine 10, only the stirring cup 20 is taken for use, therefore, before the stirring cup 20 is installed, the motor assembly 30 is lifted by the rotating platform 60, so that the output end of the motor assembly 30 can be retracted upward to avoid the upper end of the stirring cup 20 and the stirring piece 21, which facilitates the user to install the stirring cup 20 on the support base 11; after the stirring cup 20 is installed in place, the motor assembly 30 is lowered by the rotating platform 60 of the same specification, so that the output end of the motor assembly 30 can be closely inserted and matched with the top end of the stirring piece 21, to realize reliable transmission.

[0078] It should be noted that the rotating platform and the lifting mechanism described above can still be applied to the main machine top-mounted type food processor. For the ordinary food processor with the main machine 10 mounted on the stirring cup 20, the rotating platform 60 is arranged in the main machine 10 to realize the lifting of the motor assembly 30 relative to the bottom cover 101, so that when the user needs to use, the motor assembly 30 is lowered relative to the bottom cover 101 to drive the output end to be in transmission connection with the stirring piece 21, and when the user finishes using, the motor assembly 30 is lifted relative to the bottom cover 101 by the rotating platform 60, so that the output end of the motor assembly 30 is retracted into the main machine 10, which on one hand avoids the danger caused by the rotation of the output end due to the user's misoperation of the switch button, and on the other hand avoids the contact of the water flow with the output end during the cleaning process, thus improving the use safety and facilitating the user to clean or rinse the surface of the main machine 10.

[0079] In addition, the specific installation position of the lifting mechanism is different based on the fixed support structure provided in different embodiments, which will be described taking the embodiment 1 as an example:

[0080] As shown in Figure 3 , the fixed support 40 further comprises a first support 41 and a second support 42, the second support 42 is fixedly connected to the outer periphery of the reduction box 32, and the second support 42 is fixedly connected with the extension part 411. The lifting mechanism 50 comprises a sliding groove 51 and a movable pin 52. In the embodiment, the movable pin 52 is arranged on the second support, and the sliding groove 51 is arranged on the rotating platform 60. Specifically, the rotating platform 60 comprises a horizontally extending tray 61 and a ring wall 62 protruding from the tray 61, and the sliding groove 51 is formed in the ring wall 62. The sliding groove 51 is inclined downward along the rotating direction of the rotating platform 60, so that the movable pin 52 has a first position and a second position higher than the first position. When the movable pin 52 is in the first position, the output end of the motor assembly 30 is inserted with the stirring piece 21.

[0081] Since the motor assembly needs to be lifted, the first support and the second support need to have a certain lifting allowance when connected with the bottom cover. Specifically, as shown in Figures 2-4 , a fixed column 102 is mounted on the bottom cover 101. Preferably, as shown in Figure 4 , the bottom cover 101 is provided with a hollow insertion column 106, the fixed column 102 is fixedly inserted into the insertion column 106, the first support 41 is provided with a fixed lug 412 sleeved on the fixed column 102, and the second support 42 is provided with a fixed hole 423 corresponding to the position of the fixed lug 412. As shown in Figure 5 , the fixed column 102 passes through the fixed lug 412 and the fixed hole 423 in sequence and is inserted into the insertion column 106, thereby realizing the connection of the first support 41, the second support 42 and the bottom cover 101. The fixed column 102 is provided with an upper limiting part 103 and a lower limiting part 104 stopping on the upper and lower sides of the fixed lug 412 and the fixed hole 423. In the embodiment, as shown in Figure 5 , a snap spring is sleeved on the upper end of the fixed column to form the upper limiting part 103, the upper end surface of the insertion column 106 protrudes radially from the fixed column to form the lower limiting part 104, the upper end of the insertion column 106 is supported on the lower limiting part 104 by the fixed lug 412, and an active gap S is formed between the fixed lug 412 and the upper limiting part 103. A spring 105 is sleeved on the outer periphery of the fixed column 102 and abuts between the fixed lug 412 and the lower limiting part 104, and the fixed lug 412 is floatingly supported by the spring 105. In addition, in the embodiment, in order to enable the rotating platform to rotate without deviating from the bottom cover, as shown in Figure 3 , a waist-shaped hole 63 is provided through the tray 61 of the rotating platform 60. In combination with Figure 4 , the insertion column 106 protruding from the bottom cover is inserted into the waist-shaped hole 63, which can realize the connection of the fixed support and the insertion column, and also can limit the rotating stroke of the rotating platform by cooperation of the insertion column and the waist-shaped hole.

[0082] In combination with Figure 6 ,Figure 6 This diagram illustrates the connection state of the first bracket, second bracket, and bottom cover when the movable pin is in the first position. At this time, the motor assembly is in the low position, and the output end of the motor assembly 30 is inserted into the stirring component 21. Because a movable gap S1 is provided between the fixing lug 412 of the first bracket and the upper limit part 103, the motor assembly has an upward movable stroke, and the upper limit part 103 restricts the first bracket from disengaging from the fixing post 102. Combined with... Figure 7 As shown, Figure 7 The diagram illustrates the connection state of the first bracket, the second bracket, and the bottom cover when the movable pin is in the second position. At this time, the motor assembly is in a high position, and the output end of the motor assembly 30 is disengaged from the stirring component 21. There is a movable gap between the lower limit part 104 and the edge of the fixing hole of the second bracket 42, so that the motor assembly has a downward movable stroke.

[0083] By configuring the lifting mechanism 50 with a sliding groove 51 and a movable pin 52, the wall of the sliding groove 51 axially limits the movable pin 52, supporting it to prevent it from falling downwards and simultaneously limiting its upward movement to prevent it from detaching from the sliding groove 51. Therefore, the movable pin 52 and the sliding groove 51 are stably connected and do not detach, enabling the first support 41 or the second support 42 to smoothly lift and lower the motor assembly 30, and ensuring a tight connection and reliable transmission between the output end of the motor assembly 30 and the stirring component 21. It is understood that the positions of the sliding groove and the movable pin can be interchanged.

[0084] For ease of operation, such as Figure 3 As shown, a lever 601 protrudes from the side of the rotating platform 60. Preferably, an arc-shaped plate 603 is provided on the side of the rotating platform 60, and the lever 601 protrudes from the outer side of the arc-shaped plate 603. The arc-shaped plate 603 is configured to conform to the side wall of the main unit's housing. An clearance opening 107 is opened on the side wall of the main unit's housing. The lever 601 extends out of the main unit's housing from the clearance opening. An end cap 602 is provided at the end of the lever 601 to facilitate user gripping and improve aesthetics.

[0085] Preferably, such as Figure 5 As shown, a limiting member 70 is fixed on the bottom cover 101. The limiting member 70 includes a connecting plate 71 that protrudes upward from the upper surface of the bottom cover 101 and a pressure plate 72 that is laterally bent from the top of the connecting plate 71. A limiting groove is formed between the pressure plate 72 and the upper surface of the bottom cover 101. The edge of the rotating platform 60 is inserted into the limiting groove and rotates along the limiting groove.

[0086] In use, the user only needs to slide the lever 601 along the clearance opening, which will directly drive the rotating platform 60 to rotate. With the cooperation of the movable pin and the slide groove, the first bracket and the second bracket will drive the motor assembly to achieve lifting and lowering, and the operation is smooth.

[0087] By fixing the limiting piece 70 on the bottom cover 101, the limiting piece 70 is connected with the bottom cover 101 through the connecting plate 71 and forms a limiting groove between the bottom cover 101 and the pressing plate 72, the edge of the rotating platform 60 is inserted into the limiting groove to be axially limited, when the edge of the rotating platform 60 rotates along the limiting groove, the rotating guiding effect is realized, and the situation that the edge of the rotating platform 60 is warped and the rotation is not smooth is prevented.

[0088] It can be understood that the lifting mechanism can also be applied to the embodiment in which the fixed support only has the first support, specifically, the lifting mechanism 50 comprises a sliding groove 51 opened in one of the first support 41 and the rotating platform 60 and a movable pin 52 arranged on the other one of the first support 41 and the rotating platform 60 and sliding along the sliding groove 51, the sliding groove 51 is arranged downwardly and inclined along the rotating direction of the rotating platform 60, so that the movable pin 52 has a first position and a second position higher than the first position, and when the movable pin 52 is in the first position, the output end of the motor assembly 30 is inserted with the stirring piece 21.

[0089] Since the motor assembly needs to be lifted, the first support and the bottom cover need to have a certain lifting allowance while being connected, specifically, the bottom cover 101 is provided with a fixed column 102, the first support 41 is provided with a fixed lug 412 sleeved on the fixed column 102, the fixed column 102 is provided with an upper limiting part 103 and a lower limiting part 104 stopping on both sides of the fixed lug 412, the fixed lug 412 is supported on the lower limiting part 104, and an active gap is arranged between the fixed lug 412 and the upper limiting part 103, and the spring 105 abutting between the fixed lug 412 and the lower limiting part 104 is arranged on the outer periphery of the fixed column 102.

[0090] By installing the fixed column 102 on the bottom cover 101 and arranging the fixed lug 412 on the first support 41, the alignment and installation between the first support 41 and the bottom cover 101 are facilitated, the fixed lug 412 is limited between the upper limiting part 103 and the lower limiting part 104 to realize the axial installation and limitation of the first support 41 and the bottom cover 101, the active gap is arranged between the fixed lug 412 and the upper limiting part 103 to enable the first support 41 to be connected with the bottom cover 101 in a lifting manner and drive the motor assembly 30 to lift, the spring 105 abutting between the fixed lug 412 and the lower limiting part 104 is used to buffer the fixed lug 412 when it is lowered to avoid the situation that the motor assembly 30 directly falls and collides, and when the fixed lug 412 is raised, the elastic force of the spring 105 provides an auxiliary force to make the lifting operation of the user labor-saving and the operation feeling good.
