Description

TECHNICAL FIELD

[0001] The application belongs to the field of food processors, and particularly relates to a food processor with optimized heat dissipation. BACKGROUND

[0002] The main electrical components of a food processor include a motor and a power board, and research has found that the heat dissipation requirement of the power board is lower than that of the motor during the operation of the machine. The power board can meet the heat dissipation requirement through natural heat dissipation or heat dissipation with the help of a heat dissipation air duct.

[0003] In the existing food processor with an integrated cup body and motor, the power board is arranged in the main machine, and an air inlet and outlet duct is arranged in the main machine. The air inlet and outlet duct occupies a large space inside the main machine. When the power board is arranged in the air duct, a large air duct space or a long heat dissipation path needs to be arranged to ensure the heat dissipation effect of the power board. However, such a design will result in a large volume of the main machine, which is not conducive to the miniaturization of the machine. When the power board is arranged outside the air duct, the air inlet and outlet duct has already occupied a large space in the main machine, resulting in a small available space in the main machine. The power board cannot be sufficiently cooled in the small space. If a separate heat dissipation channel is arranged for the power board to enhance heat dissipation, the internal structure of the main machine will be complicated and the volume of the main machine will be increased. Therefore, it is difficult to balance the heat dissipation of the power board and the reasonable distribution of the internal structure of the main machine. CONTENT OF THE UTILITY MODEL

[0004] The application provides a food processor with optimized heat dissipation, which aims to solve the technical problems of unreasonable internal layout of the main machine in the existing motor and power board separation scheme, poor heat dissipation effect of the power board when the power board is arranged outside the air duct, and limitation of the installation position of the main machine and cup body assembly due to the arrangement of the heat dissipation air duct.

[0005] The technical scheme adopted by the application is as follows:

[0006] The application provides a food processor with optimized heat dissipation, which aims to solve the technical problems of unreasonable internal layout of the main machine in the existing motor and power board separation scheme, poor heat dissipation effect of the power board when the power board is arranged outside the air duct, and limitation of the installation position of the main machine and cup body assembly due to the arrangement of the heat dissipation air duct.

[0007] The food processor of the present application adopts the technical solution that the power board is arranged outside the air duct, so as to avoid the influence of the heat generated by the power board on the heat dissipation of the motor. On this basis, the spatial arrangement of the host is optimized and adjusted, and a heat dissipation area is divided at the rear side in the host, which only occupies a small space in the host, so that the host has a larger proportion of space to accommodate the power board, thereby allowing the power board to have a larger space for heat dissipation to meet its heat dissipation requirements. Without the need to arrange a separate heat dissipation structure for the power board, the heat dissipation requirements of the power board can also be fully met, the internal structure of the host is simple, the space utilization of the host is reasonable, the volume of the host is not increased, and the miniaturization of the host is facilitated.

[0008] The power board is arranged transversely and at least partially corresponds to the brushless motor, which can avoid the increase of the height of the host caused by the longitudinal arrangement of the power board, thereby avoiding the increase of the height of the whole machine and the instability of operation. On the other hand, since the power board and the brushless motor overlap in the vertical direction, compared with the parallel arrangement of the power board and the brushless motor, the size of the host in the radial direction is reduced, thereby further facilitating the miniaturization of the host. The heat dissipation path of the brushless motor includes the paths of the air inlet and the air outlet inside the cup assembly in addition to the air inlet duct and the air outlet duct. Overall, the heat dissipation path is long enough to meet the heat dissipation requirements of the motor, thereby ensuring the performance and service life of the motor. The positioning ring can realize the positioning of the cup assembly in the axial and radial directions, which is conducive to the rapid installation of the cup assembly and the improvement of the stability of the operation of the cup assembly. In addition to providing the installation and positioning of the cup assembly, the hollow structure inside the positioning ring can be used to arrange the air duct, and the ventilation opening is arranged to realize the communication between the air ducts of the host and the cup assembly, thereby expanding the space utilization and function of the positioning ring and providing a new idea for the design of the heat dissipation air duct structure.

[0009] Optionally, the air inlet duct and the air outlet duct are arranged adjacent to each other and within the range of the straight angle of the center of the circle where the positioning ring is located.

[0010] In the present technical solution, the heat dissipation area formed by the air inlet duct and the air outlet duct is arranged within a small circular arc range, occupies a small space in the host, and is arranged more compactly within the straight angle range of the host. While meeting the heat dissipation of the cup, the remaining heat dissipation space in the host is maximized, which is conducive to the self-heat dissipation of the power board. Moreover, the air inlet duct and the air outlet duct are respectively communicated with the cup assembly at similar positions, thereby fully utilizing the space inside the cup assembly. The airflow takes a long path in the cup assembly before reaching the air outlet duct, thereby prolonging the heat dissipation path, improving the heat dissipation effect of the motor, and facilitating the consumption of noise energy and the reduction of the noise size transmitted to the outside.

[0011] Optionally, the positioning ring is an annular ring with a gap, the host computer comprises a coupler arranged at the gap of the positioning ring, the power board is at least partially located inside the positioning ring in the vertical direction, and the air inlet duct and the air outlet duct are located at the back side of the line formed by the center of the circle where the positioning ring is located and the center of the coupler.

[0012] In the technical solution, the positioning ring is an open annular ring, the coupler is arranged in the gap, the space utilization can be improved, the positioning ring and the coupler are arranged close to the periphery of the host computer to support the cup body assembly together, the stability of the cup body assembly in operation can be improved, the cup body assembly can be less shaken, and the use is more reliable. Generally, the center axis of the motor corresponds to the center of the circle where the positioning ring is located, the motor is located inside the positioning ring, and by making the power board at least partially located inside the positioning ring in the vertical direction, the power board and the brushless motor can be overlapped in the vertical direction, which is beneficial to reducing the size of the host computer in the radial direction.

[0013] Optionally, the first air vent and the second air vent are located on the upper end of the inner wall of the positioning ring.

[0014] In the technical solution, the air vent is a side opening, compared with the opening arranged upward, the water, dust and other foreign matters falling can be effectively prevented from entering the host computer through the air vent, the short circuit of the internal circuit of the host computer can be avoided, and the service life of the machine can be prolonged; and when the airflow enters the cup body assembly from the host computer upward, the airflow needs to pass through the first air vent to turn into the cup body assembly, or when the airflow enters the host computer from the cup body assembly downward, the airflow needs to pass through the second air vent to turn into the air outlet duct, the airflow turning is beneficial to prolonging the airflow path compared with the airflow flowing upward or downward directly, which can improve the heat dissipation effect, increase the noise energy consumption, and reduce the transmission of noise.

[0015] Optionally, the host computer is provided with a heat dissipation hole corresponding to the power board.

[0016] In the technical solution, by arranging the heat dissipation hole, the external cold air can enter the host computer through the heat dissipation hole to accelerate the cooling of the power board, and the heat can be discharged, so that the heat dissipation effect of the power board can be improved.

[0018] In the technical solution, the air inlet air duct is formed in the inner side of the hollow positioning ring, which is simpler in structure and higher in space utilization than setting a special air inlet structure; the air inlet opening of the main machine is a horizontal opening, which is vertically communicated with the air inlet air duct to form a straight air inlet path, so that the air inlet resistance is small and the air inlet is smooth, and the heat dissipation efficiency is improved. At the same time, the air inlet air duct is directly formed in the inner side of the positioning ring, and the air inlet air duct located in the main machine is also limited in the right angle range defined by the positioning ring, so that the space occupied by the air inlet air duct in the main machine is reduced, the space ratio of the space for placing the power board in the main machine is improved, and the heat dissipation efficiency of the power board is improved.

[0019] Optionally, a first sealing member is arranged between the lower end of the air inlet air duct and the air inlet opening of the main machine.

[0020] In the technical solution, the first sealing member is arranged to completely isolate the air inlet path from the space where the power board is located in the main machine, so that external water, dust and the like cannot enter the main machine through the interface between the air inlet air duct and the air inlet opening of the main machine to damage the power board, thereby prolonging the service life of the power board.

[0021] Optionally, the main machine comprises a main machine upper shell and a main machine base, the main machine base is provided with an air outlet opening of the main machine, and an air outlet air duct is arranged between the main machine upper shell and the main machine base, and the lower end of the air outlet air duct is communicated with the air outlet opening of the main machine.

[0022] In the technical solution, the air outlet air duct is formed in the space between the main machine upper shell and the main machine base, which is simple in structure and high in space utilization, and provides conditions for flexible design of the air outlet air duct. Similarly, the air outlet air duct is formed by the positioning ring and is limited in the right angle range of the positioning ring, so that the space occupied by the air outlet air duct in the main machine is reduced, especially when the air inlet air duct and the air outlet air duct are arranged adjacent to each other, the included angle range of the air inlet air duct and the air outlet air duct limited by the positioning ring can be further compressed, so that the heat dissipation demand of the cup body assembly is realized with smaller space, and the heat dissipation space of the power board is fully ensured. At the same time, the air inlet air duct and the air outlet air duct are limited in the right angle range of the positioning ring, and the first ventilation opening and the second ventilation opening are arranged on the cup body assembly, so that the mounting and positioning position between the cup body assembly and the main machine is facilitated to meet the mounting and positioning demand of different food processors.

[0023] Optionally, a second sealing member is arranged between the lower end of the air outlet air duct and the air outlet opening of the main machine.

[0024] In the technical solution, the second sealing member is arranged to completely isolate the air outlet path from the space where the power board is located in the main machine, so that external water, dust and the like cannot enter the main machine through the interface between the air outlet air duct and the air outlet opening of the main machine to damage the power board, thereby prolonging the service life of the power board, and the second sealing member can absorb part of the noise, which is conducive to reducing the air outlet noise.

[0025] Optionally, the positioning ring is arranged on the upper shell of the main machine, and a part of the inner side of the positioning ring extends vertically downward to form the air outlet air duct, the lower end of the air outlet air duct is vertically communicated with the main machine air outlet on the bottom wall of the main machine base, or a part of the lower side of the positioning ring is provided with an air duct connecting piece, the positioning ring and the air duct connecting piece are communicated to form the air outlet air duct, the upper end of the air duct connecting piece is vertically communicated with the positioning ring, and the lower end of the air duct connecting piece is horizontally bent and horizontally communicated with the main machine air outlet on the side wall of the main machine base.

[0026] In the technical solution, the air outlet air duct includes two forms, one is a straight air outlet path, the air duct structure is simple, and air outlet is smooth and efficient, and the other is a bent air outlet path, the path is longer, and air exhaust and heat dissipation are beneficial to noise reduction; when air is horizontally exhausted, hot air flow is more easily and quickly dispersed around, the hot air flow can be prevented from gathering around the main machine to cause the main machine shell to be hot, and air outlet effect is better.

[0040] As Figures 1 to 5As shown, the food processor provided by the present application optimizes heat dissipation, which comprises a cup assembly 10 provided with a brushless motor 101 and a main machine 11. The main machine 11 is provided with a power board 12 for driving the brushless motor 101. The main machine 11 is provided with an upper convex positioning ring 13 for positioning the cup assembly 10. The power board 12 is arranged transversely and at least partially corresponds to the brushless motor 101. A heat dissipation area is divided at the rear side of the main machine 11. The heat dissipation area is provided with an air inlet duct 14 and an air outlet duct 15 which are communicated with the cup assembly 10. The positioning ring 13 is provided with a first air vent 131 for communicating the air inlet duct 14 with the cup assembly 10 and a second air vent 132 for communicating the air outlet duct 15 with the cup assembly 10. External airflow enters the cup assembly 10 through the first air vent 131 and the air inlet duct 14 to dissipate heat from the brushless motor 101. The heat dissipation airflow is discharged through the second air vent 132 and the air outlet duct 15.

[0041] The food processor of the present application prolongs the technical scheme that the power board 12 is arranged outside the air duct to avoid the heat generated by the power board 12 from affecting the heat dissipation of the motor. On this basis, the spatial arrangement of the main machine 11 is optimized. A heat dissipation area is divided at the rear side of the main machine 11. The heat dissipation area only occupies a small space in the main machine 11, so that the main machine 11 has a larger proportion of space for accommodating the power board 12. Therefore, the power board 12 has a larger space for heat dissipation to meet its heat dissipation requirements. The power board 12 does not need to be provided with a separate heat dissipation structure to fully meet the heat dissipation requirements of the power board 12. The internal structure of the main machine 11 is simple, and the space utilization of the main machine 11 is reasonable. The volume of the main machine 11 will not be increased, which is conducive to the miniaturization of the main machine 11.

[0042] The power board 12 is arranged transversely and at least partially corresponds to the brushless motor 101. On the one hand, it can avoid the increase of the height of the main machine 11 caused by the longitudinal arrangement of the power board 12, which leads to the increase of the height of the whole machine and causes unstable operation. On the other hand, since the power board 12 and the brushless motor 101 overlap in the vertical direction, compared with the parallel arrangement of the power board 12 and the brushless motor 101, it is conducive to reducing the size of the main machine 11 in the radial direction, and further promotes the miniaturization of the main machine 11. The heat dissipation path of the brushless motor 101 includes not only the air inlet duct 14 and the air outlet duct 15, but also the air inlet and outlet paths inside the cup assembly 10. Overall, the heat dissipation path is long enough to meet the heat dissipation requirements of the motor, thereby ensuring the performance and service life of the motor. The positioning ring 13 can realize the positioning of the cup assembly 10 in the axial and radial directions, which is conducive to the quick installation of the cup assembly 10 and improves the stability of the operation of the cup assembly 10. In addition to providing installation and positioning of the cup assembly 10, the hollow structure inside the positioning ring 13 can be used to arrange the air duct. At the same time, the air vents are arranged to realize the communication between the air duct of the main machine 11 and the cup assembly 10, which expands the space utilization and function of the positioning ring 13 and provides a new idea for the design of the heat dissipation air duct structure.

[0043] like Figure 1 As shown, since the motor is located in the cup assembly 10, the space occupied by the motor in the main unit 11 is reduced. Therefore, the main unit 11 can adopt a thinner frame structure. Moreover, the size of the variable frequency brushless motor 101 is relatively small, which avoids the overall height of the cup assembly 10 being too large, so that the center of gravity of the whole machine is not too high, ensuring the stability of the machine operation. The power board 12 is located near the middle area of ​​the main unit 11 and has a large installation space, for example, it occupies no less than 1 / 3 of the space of the main unit 11 radially. The heat dissipation requirements can be met by natural heat dissipation in the large heat dissipation space. The air inlet and outlet duct structure is located near one edge of the main unit 11, which only requires a small proportion of the space of the main unit 11. Under the limited space of the main unit 11, more space is left for the power board 12 to dissipate heat. This can not only ensure the heat dissipation effect of the motor and the power board 12, but also make full use of the space of the main unit 11, optimize the structural layout, and not increase the size of the main unit 11.

[0044] It is understandable that the power board 12 can dissipate heat naturally within the host unit 11. The host unit 11 can be equipped with ventilation holes that connect to the outside at the corresponding positions of the power board 12 to enhance the exchange of air between the inside and outside, thereby improving the heat dissipation effect of the power board 12. Of course, the host unit 11 may also not have ventilation holes, and the heat from the power board 12 can still be dissipated naturally through the larger space inside the host unit 11, thus achieving heat dissipation. Moreover, the interior of the host unit 11 is not a completely sealed space; there is still airflow exchange in relevant locations, which can assist in the heat dissipation of the power board 12.

[0045] The cup assembly 10 has a cup inlet and a cup outlet. After the cup assembly 10 is installed in place with the main unit 11, the cup inlet connects to the first ventilation port 131, and the cup outlet connects to the second ventilation port 132, thus connecting the cup assembly 10 and the main unit 11 and enabling airflow circulation to dissipate heat from the brushless motor 101. The bottom of the cup assembly 10 has a positioning groove that mates with the positioning ring 13. The cup assembly 10 can be quickly installed and positioned by inserting it into the positioning groove and positioning ring 13. The hollow internal structure of the positioning ring 13 can also provide an air duct, expanding the function of the positioning ring 13. Compared with setting a dedicated air duct structure, this simplifies the internal structure configuration of the main unit 11 and saves costs.

[0046] In a preferred embodiment of this application, the air inlet duct 14 and the air outlet duct 15 are arranged adjacently and within the range where the central angle of the circle containing the positioning ring 13 is a right angle.

[0047] In the embodiment, the heat dissipation area formed by the air inlet duct 14 and the air outlet duct 15 is arranged in a smaller circular arc range, occupies a small host space, and the air inlet duct 14 and the air outlet duct 15 are arranged more compactly in the right angle range of the host, which meets the cup body heat dissipation while expanding the remaining heat dissipation space in the host as much as possible, is conducive to the independent heat dissipation of the power board 12. Moreover, the air inlet duct 14 and the air outlet duct 15 are respectively communicated with the cup body assembly at similar positions, which fully utilizes the space inside the cup body assembly, and the airflow takes a long path in the cup body assembly before reaching the air outlet duct, which prolongs the heat dissipation path, improves the motor heat dissipation effect, and is conducive to consuming noise energy and reducing the noise size transmitted to the outside. For example, in an embodiment, as shown in Figure 2 the air inlet duct 14 and the air outlet duct 15 are arranged in a range with a central angle α of 70°.

[0048] As a preferred embodiment of the present application, the positioning ring 13 is an annular ring with a gap 133, the host 11 includes a coupler 16 arranged at the gap 133 of the positioning ring 13, the power board 12 is at least partially located inside the positioning ring 13 in the vertical direction, and the air inlet duct 14 and the air outlet duct 15 are located on the rear side of the line formed by the center of the circle where the positioning ring 13 is located and the center of the coupler 16.

[0049] In the embodiment, the positioning ring 13 adopts a non-closed annular shape, the coupler 16 is arranged in the gap 133 space, which can improve the space utilization rate, and the positioning ring 13 and the coupler 16 are arranged close to the periphery of the host 11 to support and position the cup body assembly 10 together, which can improve the stability of the cup body assembly 10 operation and reduce the shaking of the cup body assembly 10, and is more reliable in use. Generally, the central axis of the motor corresponds to the center of the circle where the positioning ring 13 is located, and the motor is located inside the positioning ring 13. By arranging the power board 12 at least partially inside the positioning ring 13 in the vertical direction, the power board 12 and the brushless motor 101 can be overlapped in the vertical direction, which is conducive to reducing the size of the host 11 in the radial direction. As shown in Figure 2 the coupler 16 is arranged on the horizontal side of the host 11, the line connecting the center of the circle where the positioning ring 13 is located and the center of the coupler 16 divides the circle where the positioning ring 13 is located into a front half circle and a rear half circle, and the air inlet duct 14 and the air outlet duct 15 are arranged on the rear half circle and located on the rear side of the host 11. Correspondingly, the host air inlet 19 and the host air outlet 20 are also arranged on the rear side of the host 11, which is beneficial to the appearance of the machine, and the rear side air outlet can avoid scalding the user by hot air.

[0050] Preferably, as shown in Figure 2As shown, the coupler 16 extends in an arc shape, and the coupler 16 and the positioning ring 13 are located on the same circumference. Since both the coupler 16 and the positioning ring 13 have a connection and cooperation relationship with the cup assembly 10, it is beneficial for the cup assembly 10 to be aligned and installed according to the same circumference reference. This avoids the formation of multiple installation references, which would increase the installation difficulty and ensure the installation efficiency and accuracy of the cup assembly 10. Moreover, the coupler 16 and the positioning ring 13 form an approximately complete circumference, which can enhance the support and positioning effect of the cup assembly 10 and improve the stability of machine operation.

[0051] In one embodiment, the power board 12 is positioned directly opposite the brushless motor 101, such that the power board 12 is completely located inside the positioning ring 13 in the vertical direction. In this embodiment, the power board 12 and the brushless motor 101 overlap to the maximum extent, thereby minimizing the radial dimension of the host 11.

[0052] In other embodiments, such as Figure 3 As shown, a portion of the power board 12 corresponds to the positioning ring 13, while the remaining portion is located inside the positioning ring 13. A certain distance exists between the power board 12 and the air inlet / outlet ducts, providing ample space around the power board 12 for heat dissipation. This facilitates rapid and uniform heat dissipation, improving the overall cooling effect. The main unit 11 includes, for example, a main body 111 corresponding to the cup assembly 10 and a front-protruding operating part 112. The operating part 112 has an operating panel for adjusting machine functions and providing human-machine interaction. In some embodiments, the power board 12 is located only within the main body 111, which helps reduce the radial dimension of the operating part 112 and promotes miniaturization of the main unit 11. In other embodiments, the power board 12 spans both the main body 111 and the operating part 112, allowing for the installation of a larger power board 12 and flexibly adapting its type.

[0053] In a preferred embodiment of this application, the first vent 131 and the second vent 132 are located at the upper end of the inner sidewall of the positioning ring 13.

[0054] In this embodiment, the vent adopts a side opening, which can effectively prevent falling water, dust and other foreign objects from entering the main unit 11 through the vent, avoid short circuits in the main unit 11, and extend the machine's lifespan. Moreover, when the airflow enters the cup assembly 10 from the main unit 11 upwards, it needs to turn through the first vent 131 to enter the cup assembly 10, or when the airflow enters the main unit 11 from the cup assembly 10 downwards, it needs to turn through the second vent 132 to enter the air outlet duct 15. The turning of the airflow is beneficial to extending the airflow path compared to the airflow flowing straight up or straight down, which can improve the heat dissipation effect, increase noise energy consumption and reduce noise transmission.

[0055] In a preferred embodiment of this application, the host 11 is provided with heat dissipation holes corresponding to the power board 12.

[0056] In this embodiment, the external cold air can enter the main machine 11 through the heat dissipation holes to accelerate the cooling of the power supply board 12, which is conducive to heat dissipation and can enhance the heat dissipation effect of the power supply board 12. The heat dissipation holes are arranged, for example, on the bottom wall of the main machine 11 corresponding to the power supply board 12. The bottom of the main machine 11 is provided with a foot pad to form a gap between the bottom wall of the main machine 11 and the operation table top, so that the airflow flows smoothly.

[0057] As a preferred embodiment of the present application, as shown in Figure 4 The main machine 11 includes a main machine upper shell 17 and a main machine base 18. The positioning ring 13 is arranged on the main machine upper shell 17. The inner side of part of the positioning ring 13 extends vertically downward to form an air inlet air duct 14. The main machine base 18 is provided with a horizontally opened main machine air inlet 19. The lower end of the air inlet air duct 14 is vertically communicated with the main machine air inlet 19. The air inlet air duct 14 and the air outlet air duct 15 are arranged adjacently and within the range of the straight angle of the center of the circle where the positioning ring 13 is located.

[0058] In this embodiment, the air inlet air duct 14 is formed in the hollow inner side of the positioning ring 13. Compared with arranging a special air inlet structure, the structure is simple and the space utilization rate is high. The main machine air inlet 19 is a horizontal opening, which is vertically communicated with the air inlet air duct 14 to form a direct air inlet path, so that the air inlet resistance is small, the air inlet is smooth, and the heat dissipation efficiency can be improved. At the same time, the air inlet air duct 14 is directly formed in the inner side of the positioning ring 13. The air inlet air duct 14 located in the main machine 11 is also limited within the straight angle range defined by the positioning ring 13, which can reduce the space occupied by the air inlet air duct 14 in the main machine 11, improve the space proportion of placing the power supply board 12 in the main machine 11, and improve the heat dissipation efficiency of the power supply board 12.

[0059] Preferably, the first vent 131 is arranged on the inner side wall of the upper end of the positioning ring 13. The first vent 131 is a side opening, which can effectively prevent foreign matters such as falling water and dust from entering the inside of the main machine 11 through the first vent 131, so as to protect the internal structure of the main machine 11 and prolong the service life of the machine. The first vent 131 is arranged on the inner side of the upper end of the positioning ring 13, so that the convex space of the positioning ring 13 also constitutes part of the air inlet air duct 14, which is conducive to prolonging the air duct, reducing the wind noise, and reducing the probability of external water, dust and other foreign matters being sucked into the main machine 11, thereby protecting the internal structure of the main machine 11.

[0060] As shown in Figure 3 The main machine upper shell 17 and the main machine base 18 form an installation cavity. The power supply board 12 is arranged in the installation cavity. The power supply board 12 can be fixed on the main machine upper shell 17 or the main machine base 18, which is not limited in the present application. Figure 4The air inlet path is shown, and the external air enters the air inlet duct 14 vertically upward from the bottom of the main machine 11, and the air inlet is smooth and efficient. The main machine air inlet 19 is preferably convex relative to the bottom wall of the main machine base 18, which can increase the distance between the main machine air inlet 19 and the operating table, ensure smooth air inlet, and prevent water from entering.

[0061] In one embodiment, a first sealing member 21 is provided between the lower end of the air inlet duct 14 and the main machine air inlet 19.

[0062] In this embodiment, as shown in Figure 4 By providing the first sealing member 21, the air inlet path can be completely isolated from the space where the power board 12 is located in the main machine 11, which can prevent external water, dust and other substances from entering the main machine 11 through the interface between the air inlet duct 14 and the main machine air inlet 19, thereby prolonging the service life of the power board 12.

[0063] The air inlet duct 14 and the main machine air inlet 19 can be connected by plug-in connection, for example, the upper end of the main machine air inlet 19 is provided with an interface, the diameter of the interface is greater than the diameter of the bottom of the air inlet duct 14, the air inlet duct 14 is inserted into the interface, and a sealing ring is provided between the air inlet duct 14 and the interface.

[0064] As a preferred embodiment of the present application, the main machine 11 includes a main machine upper shell 17 and a main machine base 18, the main machine base 18 is provided with a main machine air outlet 20, and the main machine upper shell 17 and the main machine base 18 are provided with an air outlet duct 15, the lower end of the air outlet duct 15 communicates with the main machine air outlet 20. The air inlet duct 14 and the air outlet duct 15 are arranged adjacent to each other and within the range of the straight angle of the center of the circle where the positioning ring 13 is located.

[0065] The air outlet duct 15 is formed by the positioning ring 13, and is limited within the range of the straight angle of the positioning ring 13, which can reduce the space occupied by the air outlet duct 15 in the main machine 11, especially when the air inlet duct 14 and the air outlet duct 15 are arranged adjacent to each other, the included angle range of the air inlet duct 14 and the air outlet duct 15 limited by the positioning ring 13 can be further compressed, so that the heat dissipation demand of the cup body assembly is realized with smaller space, and the heat dissipation space of the power board 12 is fully guaranteed. At the same time, by limiting the air inlet duct 14 and the air outlet duct 15 within the range of the straight angle of the positioning ring 13, the first air vent and the second air vent are provided on the cup body assembly 10, which facilitates the installation and positioning of the cup body assembly 10 and the main machine 11, and meets the installation and positioning demand of different food processors.

[0066] The positioning ring 13 is set on the upper shell 17 of the main unit. The air outlet duct 15 includes two forms. One is a straight air outlet path. The duct structure is simple and the air outlet is smooth and efficient. For example, in one embodiment, part of the inner side of the positioning ring 13 extends vertically downward to form the air outlet duct 15. The lower end of the air outlet duct 15 is vertically connected to the air outlet of the main unit on the bottom wall of the main unit base 18. That is, the airflow is discharged vertically downward through the air outlet duct 15 and the air outlet of the main unit.

[0067] Another type is a bent air outlet path, which is longer and helps reduce noise while dissipating heat. When using a horizontal air outlet, the hot airflow can more easily and quickly disperse to the surroundings, preventing the hot airflow from accumulating near the host unit 11 and causing the host unit 11 casing to overheat, resulting in better airflow performance. For example, in one embodiment, such as Figure 5 As shown, a duct connector 22 is provided below part of the positioning ring 13. The positioning ring 13 and the duct connector 22 are connected to form an air outlet duct 15. The upper end of the duct connector 22 is vertically connected to the positioning ring 13, and the lower end of the duct connector 22 is horizontally bent and horizontally connected to the main unit air outlet 20 on the side wall of the main unit base 18. Figure 5 As shown, the airflow first flows vertically downwards along the air outlet duct 15, then turns horizontally and is discharged through the main unit's air outlet 20. Preferably, the main unit's air inlet 19 is located on the bottom wall of the main unit base 18, and the main unit's air outlet 20 is located on the side wall of the main unit base 18. This prevents a portion of the hot air discharged from the main unit's air outlet 20 from easily flowing back into the main unit's air inlet 19 when both the main unit's air inlet 19 and air outlet 20 are horizontally positioned, thus ensuring the overall heat dissipation effect of the machine. Preferably, the second vent 132 is located on the inner side wall of the upper end of the positioning ring 13. The second vent 132 is a side opening, which can effectively prevent falling water, dust, and other foreign objects from entering the main unit 11 through the second vent 132, thereby protecting the internal structure of the main unit 11 and extending the machine's lifespan.

[0068] Furthermore, a second sealing element 23 is provided between the lower end of the air outlet duct 15 and the air outlet 20 of the main unit.

[0069] In this embodiment, by setting the second sealing element 23, the air outlet path can be completely isolated from the space where the power board 12 is located inside the host 11. This can prevent external water, dust, etc. from entering the host 11 through the interface between the air outlet duct 15 and the host air outlet 20 and damaging the power board 12, thereby extending the service life of the power board 12. Moreover, the second sealing element 23 can absorb some noise, which helps to reduce the air outlet noise.
