[0070] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0071] Combine the following Figures 1 to 15 , describing an embodiment of the present invention.

[0072] According to an embodiment of the present invention, on the one hand, a base assembly is provided, including: a bottom shell, on which at least one first limiting structure 401 is provided; a bottom plate 11, which is connected to the bottom shell, and a hollow cavity is formed between the bottom plate 11 and the bottom shell; an air duct assembly 14, which is arranged in the hollow cavity, and on which a second limiting structure is provided; and a main board 10, which is fixed in the hollow cavity by the first limiting structure 401 and the second limiting structure.

[0073] By setting a first limiting structure 401 on the bottom shell and a second limiting structure on the air duct assembly, the first limiting structure 401 and the second limiting structure cooperate to achieve a fixed connection to the main board 10, and the main board 10 can be quickly assembled and fixed in the hollow cavity of the bottom plate, that is, only the structure on the base assembly is used to fasten the main board 10, and there is no need to use screws to assemble the main board 10, which can reduce assembly parts and reduce costs.

[0074] Among them, the first limiting structure 401 is arranged at one end of the main board 10, the second limiting structure includes a third limiting structure, and the third limiting structure is arranged at the other end of the main board. The first limiting structure cooperates with the third limiting structure to limit the displacement of the main board in the up and down directions.

[0075] Specifically, Figure 3 and Figure 4 As shown, a limiting groove is provided on the first limiting structure 401, and the mainboard 10 is provided in the limiting groove, so that the mainboard 10 can be better limited and supported when the mainboard 10 is assembled on the base assembly.

[0076] like Fig. 9As shown, a third limiting structure 1401 is provided on the upper air duct of the air duct assembly, and the third limiting structure 1401 is connected to the other end of the mainboard. Specifically, the third limiting structure 1401 is a positioning groove. By providing the third limiting structure 1401 on the air duct assembly, and the third limiting structure 1401 is connected to the other end of the mainboard, the air duct assembly and the bottom shell can cooperate together to limit the upper and lower ends of the mainboard respectively, so as to realize the rapid assembly and fixation of the mainboard. As a convertible embodiment, the third limiting structure 1401 can also be set to multiple.

[0077] When the installation is completed, the upper end of the mainboard 10 is installed in the limiting groove of the bottom shell, and the lower end of the mainboard 10 is fixedly connected to the positioning groove of the air duct assembly 14.

[0078] The first limiting structure 401 and the third limiting structure 1401 limit the upper end and the lower end of the mainboard respectively. The second limiting structure also includes two fourth limiting structures 1402, which are arranged on the upper air duct of the air duct assembly. The positions of the two fourth limiting structures 1402 correspond to the positions of the two side walls of the mainboard respectively. The fourth limiting structure 1402 is connected to the side wall of the mainboard and is suitable for limiting the displacement of the mainboard 10 along the front-to-back direction, where the front-to-back direction is the direction perpendicular to the paper surface. Specifically, the fourth limiting structure 1402 is a limiting groove, and the extension direction of the limiting groove is the same as the extension direction of the side wall.

[0079] By setting the fourth limiting structure 1402 on the upper air duct, the side wall of the main board 10 can be limited to restrict the movement of the main board 10 in the front and rear directions. The first limiting structure 401, the third limiting structure 1401 and the fourth limiting structure 1402 can simultaneously limit the upper and lower ends and the left and right sides of the main board. During assembly, the two side walls of the main board can be respectively inserted downward along the two limiting grooves until the lower end of the main board is inserted into the third limiting structure 1401, thereby improving the reliability of the main board assembly.

[0080] As a convertible implementation, only the first fourth limiting structure 1402 may be provided, corresponding to one side wall of the mainboard 10 ; or more fourth limiting structures 1402 may be provided, respectively corresponding to two side walls of the mainboard 10 .

[0081] like Figures 9 to 11As shown, the two side walls of the main board 10 are respectively provided with shoulder structures 1001 inwardly concave; the upper air duct of the air duct assembly is provided with two receiving structures 1403 arranged in coordination with the shoulder structures 1001, and the receiving structures 1403 are provided with a fourth limiting structure 1402. By providing the shoulder structure 1001 on the side wall of the main board, providing the receiving structure 1403 arranged in coordination with the shoulder structure 1001 on the upper air duct, and providing the fourth limiting structure 1402 on the receiving structure 1403, when the side wall of the main board is provided on the fourth limiting structure 1402, the shoulder structure 1001 can be overlapped on the receiving structure 1403, so as to limit the main board and bear the load of the main board better. As a convertible embodiment, it can also be that the specific number of the shoulder structures 1001 and the receiving structures 1403 is set according to actual needs, and no excessive restrictions are made here. The second limiting structure in this embodiment includes at least one fifth limiting structure 1404, and at least one sixth limiting structure 1002 is provided on the main board 10. The sixth limiting structure 1002 cooperates with the fifth limiting structure 1404 to be connected to the main board 10. By providing the fifth limiting structure 1404 on the air duct assembly, providing the sixth limiting structure 1002 on the main board 10, and the fifth limiting structure 1404 cooperates with the sixth limiting structure 1002 to achieve a fixed connection to the main board 10, so that the main board 10 is more tightly connected, and the reliability of assembly is achieved. Fig. 9 and Fig.10 As shown, in this embodiment, two fifth limiting structures 1404 and six limiting structures 1002 are respectively provided, and the two sixth limiting structures 1002 are respectively provided on the two side walls of the main board 10, and the two fifth limiting structures 1404 are provided on the air duct assembly 14 at positions corresponding to the side walls of the main board 10. The first limiting structure 401 is used to limit one end of the main board 10, and by providing two sixth limiting structures 1002, which are respectively located on the two side walls of the main board 10, the two side walls of the main board 10 can be fixed when the main board 10 is assembled with the air duct assembly 14, so that the fastening of the main board 10 is more secure.

[0082] As a convertible implementation, the fifth limiting structure 1404 and the sixth limiting structure 1002 can be provided with one, three or more respectively according to actual needs, and no excessive restrictions are made here. As a convertible implementation, the sixth limiting structure 1002 is not provided on the side wall of the mainboard 10, but is provided at the end of the mainboard 10.

[0083] Specifically, the fifth limiting structure 1404 is an elastic buckle, and the sixth limiting structure 1002 is a slot, so that the fixing structure of the mainboard 10 and the air duct assembly 14 is relatively simple, and the mainboard 10 can be fastened by elastic deformation of the elastic buckle. As a convertible embodiment, the fifth limiting structure 1404 can also be a slot, and the sixth limiting structure 1002 can be an elastic buckle.

[0084] By providing a card slot on the side wall of the main board 10 and providing an elastic card buckle on the upper air duct to cooperate with the card slot, when the main board 10 is inserted into the third limiting structure 1401 and the fourth limiting structure 1402, the elastic card buckle can be connected to the card slot, and the main board 10 is pre-installed and fixed to prevent the displacement of the main board 10, and the use of screws to fix the main board in the related art is avoided, which is time-consuming and labor-intensive. As a convertible implementation, it is also possible to provide an elastic card buckle on the main board 10 and a card slot on the upper air duct.

[0085] In order to facilitate assembly, the dimensions of each structure can be set as follows: the fourth limiting structure 1402 on the upper air duct is set to have a width of 1.8mm-2.5mm, an effective length of 2.5mm-4mm, a depth of 5mm-8mm, and a bevel chamfer; the third limiting structure 1401 on the upper air duct is set to have a width of 1.7mm-2.0mm, a length of 1.2mm-2.0mm, a depth of 2.5mm-3mm, and a bevel chamfer; the first limiting structure 401 is set to have a width of 1.7mm-2.0mm, a length of 0.8mm-2mm, and a depth of 1.5mm-3mm. Of course, in actual settings, it can also be set according to actual conditions, and there is no excessive restriction here.

[0086] When installing the main board 10, first pre-install the main board 10 and the upper air duct of the air duct assembly 14, insert the side wall of the main board 10 into the fourth limiting structure 1402, and use the fourth limiting structure 1402 on the upper air duct to limit the side wall of the main board 10 and the supporting structure 1403 to bear the weight of the shoulder structure 1001 of the main board 10, and then use the third limiting structure 1401 to limit and position the bottom end of the main board 10, and the elastic buckle on the upper air duct to clamp the main board 10, so as to realize the pre-installation and clamping of the main board 10, and then when the first shell body 1 of the bottom shell and the air duct assembly 14 are assembled, the first limiting structure 401 on the second connecting structure 4 clamps the top of the main board 10, so as to realize the rapid assembly and fixation of the main board 10.

[0087] The bottom shell includes a first shell body 1, a mounting seat 2 and at least one connecting structure, which is arranged at an angle, with one end of the connecting structure connected to the first shell body 1, and the other end connected to the mounting seat 2; one side of the mounting seat 2 and one side of the connecting structure are arranged to form an installation cavity 5, and the installation cavity 5 is suitable for installing a machine base component; the other side of the first shell body 1, the mounting seat 2 and the other side of the connecting structure are arranged to form at least one accommodating cavity.

[0088] By arranging an inclined connecting structure on the bottom shell, the mounting seat 2 and one side of the connecting structure are arranged to form an installation cavity 5 for installing the base assembly, and the other side and the first shell body 1 are arranged to form a receiving cavity, and other structures of the base assembly can be installed in the receiving cavity. When the base assembly is assembled to the mounting cavity 5, the connecting structure can guide the base assembly more conveniently, thereby facilitating assembly. In addition, the other side of the mounting cavity 5 is formed with a receiving cavity for installing other structures, so that the structure of the base assembly is relatively compact, and there is no need to expand the receiving space outward, and the overall volume of the base assembly is relatively small.

[0089] like Figure 2 As shown, in this embodiment, there are two connection structures, including a first connection structure 3 and a second connection structure 4. The first connection structure 3, the first shell body 1 and the side wall 202 of the mounting seat 2 are arranged to form a first accommodating cavity 6. The second connection structure 4, the first shell body 1 and the side wall 202 of the mounting seat 2 are arranged to form a second accommodating cavity 7. The first accommodating cavity 6 and the second accommodating cavity 7 are respectively arranged on both sides of the mounting cavity 5. By arranging the first accommodating cavity 6 and the second accommodating cavity 7 on both sides of the mounting cavity 5, the structure is relatively compact, and there will be no interference when installing other structures of the base assembly in the accommodating cavity, and the installation is convenient.

[0090] As a convertible implementation, one connection structure may be provided and one accommodating cavity may be provided, or three or more connection structures may be provided and three or more accommodating cavities may be provided. Specifically, the number of structures actually required to be installed on the base assembly may be provided so as to accommodate more other structures on the base assembly and greatly improve the space utilization of the base assembly.

[0091] Four first limiting structures 401 are provided on the side of the second connection structure 4 away from the installation cavity 5, and the first limiting structures 401 are connected to the mainboard 10. That is, the mainboard 10 is installed in the second accommodating cavity 7. By providing the first limiting structures 401 on the second connection structure 4, it can play a limiting and supporting role in the installation of the mainboard 10, and the assembly is more convenient. As a convertible implementation, it is also possible that one, two, three, or more first limiting structures 401 are provided, and there is no excessive restriction here.

[0092] Reference Figure 3 As shown, the first limiting structure 401 is two square seats extending outwardly on a side of the second connection structure 4 away from the installation cavity 5, and two limiting grooves are opened on each square seat.

[0093] The bottom plate 11 is connected to the first shell body 1, and the bottom plate 11, the first shell body 1 and the lower side of the bottom wall 201 of the mounting seat 2 are surrounded to form a third accommodating cavity 8; the base assembly includes an air duct assembly 14, and the air duct assembly 14 is arranged in the third accommodating cavity 8. By providing the bottom plate 11 connected to the first shell body 1, the bottom plate 11, the first shell body 1 and the mounting seat 2 are surrounded to form the third accommodating cavity 8, and the air duct assembly 14 of the base assembly can be installed therein, so that the structure of the base assembly is more compact and the volume is smaller. As a convertible embodiment, it is also possible to install other structures on the base assembly in the third accommodating cavity 8.

[0094] The hollow cavity formed between the bottom shell and the bottom plate 11 in this embodiment is divided into an installation cavity 5 for installing the base assembly, a first accommodation cavity 6 for accommodating the knob assembly 9, a second accommodation cavity 7 for accommodating the mainboard 10, and a third accommodation cavity 8 for accommodating the air duct assembly 14.

[0095] like Figure 2 As shown, the mounting seat 2 in this embodiment includes a bottom wall 201 and a side wall 202 extending upward from the bottom wall 201, and the top of the side wall 202 is connected to the connecting structure. The mounting cavity 5 is arranged above the mounting seat 2, and the accommodating cavity is arranged on the side and bottom of the mounting seat 2.

[0096] In order to facilitate the assembly of the air duct assembly 14 , an air duct assembly screw column 2014 is further extended outward from the bottom wall 201 to facilitate the matching connection with the screw hole on the air duct assembly 14 .

[0097] Since the motor of the base assembly 02 is assembled in the mounting cavity 5, the motor will generate a lot of heat when running at high speed. In order to dissipate the heat of the motor, Figure 4 As shown, a plurality of heat dissipation holes 2011 are provided on the bottom wall 201 of the mounting base 2, which can conveniently transfer the heat of the motor to the air duct assembly 14, and then transfer and dissipate the heat from the air duct assembly 14 to the outside.

[0098] When the food processor is in use, the water in the cup may spill into the base. In order to drain the water, Figure 5 As shown, a water leakage hole 2012 is provided on the bottom wall 201. Of course, when water enters the base, the heat dissipation hole 2011 thereon can also be used as a water leakage hole.

[0099] In order to facilitate the assembly of the coupler 12 of the base assembly, a first mounting hole 2013 for mounting the coupler 12 is provided on the bottom wall 201. Specifically, the coupler 12 can be fixedly connected to the mounting base 2 by screws.

[0100] like Figure 6As shown, the base assembly includes a knob assembly 9, and the knob assembly 9 includes a display panel 901; two support structures are provided on the side of the first connection structure 3 away from the installation cavity 5, and the display panel 901 is provided on the support structure. That is, the knob assembly 9 is installed in the first accommodating cavity 6. By providing a support structure on the first connection structure 3, and providing the display panel 901 of the knob assembly 9 on the support structure, a better support effect can be achieved for the installation of the knob assembly 9, and the display panel 901 can be prevented from falling off due to vibration and accidental falling, which affects normal use.

[0101] Specifically, Figure 4 As shown, the support structure is a support rib 301. The support rib 301 is a square structure. As a convertible implementation, the support structure can also be a support groove, and the end of the display panel 901 of the knob assembly 9 is clamped in the support groove. As a convertible implementation, one, three or more support structures can be set, which can be set according to actual needs, and no excessive restrictions are made here.

[0102] In order to facilitate the installation of the knob assembly 9, a second mounting hole 101 is provided on the first shell body 1, and the knob assembly 9 is arranged in the second mounting hole 101. When the knob assembly 9 is installed in place in the second mounting hole 101, the top of the display panel 901 of the knob assembly 9 is abutted against the support rib 301, and at this time, the knob structure of the knob assembly 9 is arranged outside the second mounting hole 101, which is convenient for user operation. That is, when the installation is completed, one end of the knob assembly 9 is arranged outside the second mounting hole 101, and the other end is arranged in the first accommodating cavity 6.

[0103] like Fig.12 As shown, according to an embodiment of the present invention, on the other hand, a food processor is provided, including: a base assembly 02; a cup body assembly 03; and the above-mentioned base assembly 01, wherein the base assembly 02 is arranged in the mounting cavity 5 of the base assembly 01, and the cup body assembly 03 is arranged on the base assembly 02.

[0104] The base assembly includes a housing 13, and the shape of the housing 13 matches the shape of the mounting cavity 5. A motor assembly 15 of the food processor is disposed in the housing 13 of the base assembly. By configuring the housing 13 of the base assembly to match the shape of the mounting cavity 5, the housing 13 of the base assembly is convenient to assemble into the mounting cavity 5 of the base assembly.

[0105] Since the heat dissipation holes 2011 are arranged on the bottom wall 201 of the base assembly, the heat of the motor can be dissipated more conveniently when in use, so as to prevent the motor from being overheated and unable to be used. At the same time, in order to facilitate the heat dissipation of the motor, the motor assembly 15 also includes a heat dissipation fan, which is connected to the end of the motor away from the output shaft. Under the negative pressure of the heat dissipation fan, the air from the air inlet enters the air duct assembly, and then enters the installation cavity 5 through the air duct assembly, dissipates the heat of the motor assembly 15 in the installation cavity 5, and then transfers it to the outside through the heat dissipation holes 2011.

[0106] like Fig.14 As shown, the shell 13 includes: a second shell body 131; a base 132, which is extended from the second shell body 131 in the direction of the base assembly, and the base 132 is arranged corresponding to the mounting seat 2; a connecting portion 133 is provided between the base 132 and the second shell body 131, and the connecting portion 133 is arranged corresponding to the connecting structure of the base assembly.

[0107] Specifically, Fig.15 As shown, the base 132 includes two vertical walls 1321 and an arc-shaped wall 1322 connecting the two vertical walls 1321 ; the connecting portion 133 is obliquely disposed between the vertical walls 1321 and the second shell body 131 .

[0108] When the base assembly is assembled to the pedestal assembly, due to the setting of the vertical wall 1321 and the curved wall 1322 of the pedestal 132, after the vertical wall 1321 of the pedestal 132 cooperates with the side wall 202 of the mounting base 2, and the connecting portion 133 cooperates with the connecting structure, the base assembly can be positioned on the pedestal assembly to prevent the base assembly from shaking.

[0109] When the base assembly of the food processor is assembled on the pedestal assembly, the outer shell 13 can be first contacted with the connecting structure on the base assembly, and the outer shell 13 can be guided into the mounting seat 2 of the base assembly. Due to the setting of the connecting structure, it is more convenient to install the outer shell 13 on the base assembly. When the assembly is completed, the base 132 of the outer shell 13 is arranged on the mounting seat 2 of the base assembly, and the connecting part 133 on the outer shell 13 is arranged on the connecting structure of the base assembly. Since the outer shell 13 has the same shape as the mounting cavity 5 of the base assembly, after the assembly is completed, the outer shell 13 of the base assembly can be completely seated on the base assembly without occupying additional space, so that the overall volume of the food processor is smaller.

[0110] Since the base assembly is provided with a knob assembly 9, a main board 10 and an air duct assembly 14, and the base assembly is provided with a connecting structure, the second shell body 131 of the bottom shell, the bottom plate 11, the mounting seat 2 and the connecting structure are surrounded by three accommodating cavities, which can respectively accommodate the knob assembly 9, the main board 10 and the air duct assembly 14, so that the overall structure of the food processor is relatively compact. In addition, since the structure itself forms the installation cavity 5 for installing the outer shell 13 and the accommodating cavity for installing other structures on the base assembly, there is no need to expand the space outward, so that the overall volume of the food processor is greatly reduced.

[0111] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
