Description

Technical Field

[0001] The utility model relates to the technical field of life, and in particular to a grinding power component for a food processing machine and the food processing machine. Background Art

[0002] With the development of society and the improvement of living standards, people's pursuit of dietary diversity and healthy diet is constantly increasing. As a result, various industrial food processing machines have gradually become smaller and entered thousands of households. For example, soymilk machines not only meet people's demand for healthy and nutritious diets, but also greatly improve people's quality of life, and are therefore popular among people.

[0003] Existing food processors usually include a main unit and a crushing cup with a built-in stirring element. For example, Chinese utility model patent CN208740776U discloses a new electromagnetic heating wall-breaking machine, which includes a cup body and a base. The bottom of the cup body is detachably connected to the top of the base. The bottom of the cup body is provided with a crushing knife assembly, and the top of the base is provided with a heating assembly. The interior of the base is provided with a drive motor for driving the crushing knife assembly. The transmission between the drive motor and the crushing knife requires transmission components to be realized, that is, the top of the motor shaft of the drive motor disclosed in the patent is provided with a first drive connecting member, and the bottom of the crushing knife is provided with a second drive connecting member that cooperates with the first drive connecting member. This transmission method will cause noise between the transmission components due to transmission collision or vibration, and will cause energy loss during the transmission process, and the transmission efficiency of the whole machine is low.

[0004] For example, Chinese utility model patent CN217720848U discloses a food processing machine with a series-wound motor, which includes a main unit and a series-wound motor arranged in the main unit. The series-wound motor includes a stator and a rotor having a rotor shaft. In order to fix the series-wound motor, the patent provides a motor bracket to fix the series-wound motor in the main unit, and the motor bracket includes a front bracket and a rear bracket located at both ends of the stator core, and two oppositely arranged isolation brackets are respectively provided on the front bracket and the rear bracket.

[0005] Another food processing machine, such as Chinese utility model patent CN111493695A, discloses a wall breaking machine, which includes a machine base and a machine body, a receiving cavity is provided on the machine base, the machine body is detachably provided on the receiving cavity, a first electrical connector is provided at the bottom of the receiving cavity, the machine body includes a cup cover, a cup body, a cup base, a motor, a cutter, a heating plate assembly and a second electrical connector, that is, the motor is directly installed in the cup body assembly so that it can be detached from the main machine together with the cup body assembly. If the series motor in CN217720848U is applied In this solution, the overall weight and volume of the series-excited motor will result in a larger weight and space occupied by the cup assembly. It will be very strenuous for users to pick up the entire cup assembly, and it will be very inconvenient to store it. In addition, the motor bracket is fixed to the main unit through the front bracket and the rear bracket, which further increases the weight of the entire machine and causes the axial height of the entire machine to be too high, thereby increasing the center of gravity of the entire machine. As a result, the food processor will shake or even fall over due to the high center of gravity when processing ingredients, seriously affecting the consumer experience. Utility Model Content

[0006] The purpose of the utility model is to provide a crushing power assembly and a food processor, so as to solve the problems that the motor of the existing crushing power assembly and food processor is connected to the stirring member through a connecting member, resulting in low transmission efficiency and noise, and the motor is too large, resulting in the crushing power assembly and the entire machine being too heavy and difficult to pick up.

[0007] To achieve the above-mentioned purpose, the utility model provides a crushing power assembly, including a heating plate, and a brushless motor is also provided under the heating plate. The brushless motor includes a motor body and a motor lower shell provided on the outside of the bottom of the motor body. The motor lower shell is fixedly connected to the heating plate to fix the motor body between the motor lower shell and the heating plate, and a stirring member is fixedly connected to the top end of the motor shaft of the motor body.

[0008] The grinding power assembly of the present application is applied to a food processor. If the user needs to heat the ingredients in the grinding cup when using the food processor to process ingredients, the ingredients in the grinding cup can be heated by controlling the heating plate to increase the temperature and taste of the output ingredients. At the same time, the heated ingredients are easier to stir and process, which helps to improve the processing efficiency of the ingredients and meet the user's needs.

[0009] At the same time, a brushless motor is also installed under the heating plate. With the characteristics of the brushless motor, when the user uses the food processor to process ingredients, the motor rotation noise is lower, achieving the effect of noise reduction. At the same time, the brushless motor can achieve variable frequency control, allowing the food processor to control the brushless motor output to different speeds according to different ingredients and processing processes, which can achieve better processing effects and more complete processing of ingredients, improving the taste of the finished ingredients. In addition, the brushless motor occupies a small space, which helps to improve the compactness of the internal structure of the entire machine, reduce the space occupied by the food processor, and facilitate user storage. Moreover, compared with the traditional brushed motor, with the same output performance, due to the high power density of the brushless motor, the motor weight can be reduced by 30%. Even the use of high-grade rare earth magnets can reduce the weight by more than 40%, thereby effectively reducing the weight of the entire machine, making it easier to pick up and operate, and convenient for users to move and clean the food processor, improving the user experience.

[0010] In addition, the top end of the motor shaft of the motor body is fixedly connected to the stirring element, so that the motor shaft can be directly connected to the stirring element and thus directly drive the stirring element, eliminating the need for additional transmission components such as couplings. This not only improves the transmission efficiency of the motor, but also reduces the noise generated by transmission collision or vibration between components. It also reduces the number of parts of the whole machine, makes the internal structure more compact, and further reduces the weight of the whole machine, making it easier for users to pick up and operate.

[0011] In addition, the lower shell of the motor is fixedly connected to the heating plate to fix the motor body between the lower shell of the motor and the heating plate. On the one hand, it eliminates the need to arrange an outer shell outside the motor body and then fix the entire motor in the base through the motor bracket, which greatly simplifies the number of parts of the entire motor and the entire machine, and helps to further improve the compactness of the internal structure of the whole machine and further reduce the overall weight; on the other hand, compared with the traditional method of fixing the motor in the base through the upper motor bracket and the lower motor bracket, the entire motor body and the heating plate can be fixed by only one lower shell of the motor, further reducing the number of parts, and at the same time compressing the axial height of the integrated assembly of the brushless motor and the heating plate, so that the axial height of the whole machine is lower and thinner, further reducing the space occupied by the food processor, and at the same time reducing the center of gravity height of the whole machine, making the food processor more stable when working.

[0012] In a preferred implementation of a crushing power assembly, the motor body includes a stator assembly and a rotor assembly rotatably disposed within the stator assembly, and the motor lower shell includes a bearing portion abutting against the bottom end of the stator assembly and a connecting portion connected to the heating plate.

[0013] By configuring the motor lower shell to include a bearing portion abutting the bottom end of the stator assembly and a connecting portion connected to the heating plate, the entire motor body is clamped and fixed between the bearing portion and the heating plate, which helps to improve the stability of the motor body, and the motor lower shell does not need to limit and wrap the side wall of the stator assembly, which not only further simplifies the structure of the motor lower shell and reduces its occupied space and weight, but also increases the heat dissipation area of ​​the motor body and the heat dissipation effect of the brushless motor, avoiding the situation where the motor lower shell fully wraps the stator assembly, resulting in poor heat dissipation effect of the brushless motor, causing obvious temperature rise of the brushless motor, and serious heat aging of internal components, which helps to extend the service life of components such as the brushless motor.

[0014] In a preferred implementation of a crushing power assembly, the stator assembly includes a stator coil and a stator shell, the outer wall of the stator shell is provided with a fixing portion aligned with the connecting portion, and the crushing power assembly also includes a connecting part, which passes through the connecting portion and the fixing portion in sequence and is fixed to the heating plate.

[0015] By providing a fixing portion aligned with the connecting portion on the outer wall of the stator housing, and the food processing machine also including a connecting piece, the connecting piece passes through the connecting portion and the fixing portion in sequence and is fixed to the heating plate, so that the three components are fixedly connected after the connecting piece passes through the connecting portion and the fixing portion and is fixed to the heating plate. On the one hand, after the connecting piece passes through the fixing portion, the radial and circumferential limiting of the stator assembly can be achieved, thereby improving the position stability of the stator assembly and the entire motor body, and avoiding the circumferential or radial movement of the stator assembly of the brushless motor during operation, resulting in unstable rotation or even failure to work; on the other hand, one connecting piece can fix the stator housing, the motor body and the heating plate, which helps to improve the coaxiality of the three, thereby ensuring the stability of the rotation of the brushless motor, and can improve assembly efficiency and shorten assembly time.

[0016] In a preferred implementation of the pulverizing power assembly, the motor body includes a stator assembly and a rotor assembly rotatably disposed within the stator assembly, and the motor lower shell is a plastic package sealed around the outside of the stator assembly.

[0017] By setting the lower shell of the motor as a plastic sealing part that is sealed and wrapped around the outside of the stator assembly, not only can the motor body be fixed through the connection between the lower shell of the motor and the heating plate, but the stator assembly can also be sealed, so that the stator assembly is not exposed. At the same time, the rotor assembly has no live parts, so that even if the user sprays a small amount of water on the brushless motor when cleaning the entire machine, it will not cause internal insulation failure of the brushless motor, thereby improving the waterproofness of the brushless motor, protecting the brushless motor, improving product and user safety, and helping to extend the service life of the brushless motor.

[0018] In a preferred implementation of the pulverizing power assembly, the stator coil in the stator assembly is connected to the power line via a terminal block, the plastic package is provided with a through hole for the terminal block to pass through, and a seal is provided between the through hole and the terminal block.

[0019] By providing a through hole for the terminal to pass through in the plastic package and a sealing member between the through hole and the terminal, a seal is achieved between the through hole and the terminal. This prevents external cleaning water from flowing into the interior of the motor body, especially the stator coil, through the gap between the through hole and the terminal when the user cleans the entire machine, causing a short circuit or even damage to the brushless motor. This further improves the waterproof performance of the brushless motor and the protection of the brushless motor.

[0020] In an implementation of a food processor, the food processor further includes the grinding power assembly, the heating plate is provided below the grinding cup, the motor body is clamped and fixed between the motor lower shell and the heating plate, the food processor further includes a base connected to the bottom of the grinding cup and detachably provided on the main unit, the main unit is provided with a control module and a lower coupler electrically connected to the control module, and the base is further provided with an upper coupler electrically connected to the brushless motor and the heating plate and coupleable to the lower coupler.

[0021] The motor body is clamped and fixed between the motor lower housing and the heating plate, eliminating the need for the motor upper housing required in the prior art. This simplifies the brushless motor's accessories and optimizes and reduces the installation process for the brushless motor within the food processor, greatly improving the efficiency of brushless motor installation and significantly reducing the food processor's manufacturing costs. By incorporating a control module into the main unit, the user can control the operation of the entire machine through the control module, thereby controlling the brushless motor and heating plate to meet user needs. Compared to the traditional method of mounting the control module on the base, this further reduces the weight of the grinding cup and base, making it easier for the user to remove the grinding cup. Furthermore, when the user cleans the grinding cup, the cleaning water will not spill onto the control module, causing moisture, short circuits, or even damage to the control module and other electrical components. This protects the control module and helps extend the life of the entire machine.

[0022] In an implementation of the food processor, the main body and the base are further provided with a heat dissipation channel that is interconnected, and the food processor further includes a fan disposed in the heat dissipation channel.

[0023] By providing interconnected heat dissipation channels between the main unit and the base, and the food processor also including a fan arranged in the heat dissipation channel, the fan can drive the air flow in the heat dissipation channel during use of the food processor, so that the cold air from the outside passes into the heat dissipation channel, thereby achieving heat dissipation of the components in the heat dissipation channel, avoiding the situation where the internal components have poor heat dissipation effect and the temperature is too high for a long time, causing serious aging, which helps to extend the service life of each component.

[0024] Moreover, the heat dissipation channel in the main unit and the heat dissipation channel in the base are interconnected, which greatly improves the heat dissipation efficiency. Preferably, only one fan can be set in the heat dissipation channel to realize the flow of air in the heat dissipation channel and realize the overall heat dissipation of the entire food processor. Compared with the method of setting fans in both the base and the main unit, the number of parts is greatly simplified. One fan can realize the heat dissipation of the entire machine, which helps to further reduce the weight of the entire machine and is convenient for users to take and store.

[0025] In one implementation of the food processor, the fan is located in the base and is drivingly connected to the bottom end of the motor shaft; or,

[0026] The fan is located in the main unit, the bottom end of the motor shaft is connected to the upper coupling, and the fan is provided with a lower coupling that can be connected to the upper coupling; or,

[0027] The fan is located in the main unit, which is also provided with a drive motor for driving the fan to rotate.

[0028] By setting the fan to be located inside the base and connected to the bottom end of the motor shaft, the brushless motor can synchronously drive the fan to rotate when working, thereby realizing the flow of air in the entire heat dissipation channel and achieving heat dissipation of various components. At the same time, the motor shaft directly drives the fan, eliminating the structure of a separate transmission component, which helps to improve the transmission efficiency of the fan, while further reducing the number of components and reducing the weight of the entire machine.

[0029] By arranging the fan to be located inside the main unit, the bottom end of the motor shaft is connected to an upper coupling, and the fan is provided with a lower coupling that can be connected to the upper coupling, so that when the crushing cup and the base are installed on the main unit, the upper coupling and the lower coupling cooperate to achieve transmission connection, and the fan is arranged inside the main unit, which further reduces the weight of the crushing cup and the base, thereby further facilitating the user to take the crushing cup and the base.

[0030] By arranging the fan to be located inside the main unit, and also providing a drive motor inside the main unit to drive the fan to rotate, the fan is driven by a separate drive motor, eliminating the need for transmission components to achieve a transmission connection between the brushless motor and the fan, further simplifying the components inside the grinding cup and the base, and further reducing the weight of the grinding cup and the base, making it easier to take the grinding cup and the base.

[0031] In an implementation of a food processor, the heat dissipation channel has an air inlet and an air outlet, and the control module is located on a side close to the air inlet so that the air flow passes through the control module first and then passes through the brushless motor.

[0032] By providing the heat dissipation channel with an air inlet and an air outlet, and the control module being located on the side close to the air inlet, so that the airflow first passes through the control module and then passes through the brushless motor, the external cold air can first dissipate heat to the control module after entering the heat dissipation channel, which helps to improve the heat dissipation effect of the airflow on the control module, can reduce the impact of excessive temperature on the control module, and reduce the risk of serious aging of electrical components in the control module due to long-term high temperature, and avoid the airflow passing through other components such as the brushless motor and then passing through the control module, causing the airflow temperature to rise, resulting in poor heat dissipation effect of the airflow on the control module, so that the control module is easily damaged due to excessive temperature.

[0033] In one implementation of the food processor, the grinding cup is a vertically through-structured structure, and the heating plate abuts against the bottom end of the grinding cup to enclose the grinding cup to form a grinding chamber.

[0034] By setting the grinding cup as a top-to-bottom through structure, and the heating plate abutting the bottom end of the grinding cup to enclose the grinding cup to form a grinding chamber, the setting of the bottom wall of the grinding cup is eliminated, which not only helps to reduce the amount of demolding of the grinding cup, and thus reduces the weight of the grinding cup, thereby further reducing the weight of the whole machine and facilitating the removal of the whole machine, but also allows the heat generated by the heating plate to be directly transferred to the food, which helps to improve the heat conduction effect and improve the heating efficiency.

DETAILED DESCRIPTION

[0045] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0046] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific implementation methods disclosed below.

[0047] like Figures 1 to 6 As shown, the utility model provides a crushing power component and an easy-to-use food processor, the crushing power component includes a heating plate 4, and a brushless motor 6 is provided below the heating plate 4. The brushless motor 6 includes a motor body 61 and a motor lower shell 62 provided on the outside of the bottom of the motor body. The motor lower shell 62 is fixedly connected to the heating plate 4 to fix the motor body 61 between the motor lower shell 62 and the heating plate 4. The top end of the motor shaft of the motor body 61 is fixedly connected to the stirring member 5.

[0048] The food processor includes a main unit 1 and a grinding cup 2 with a built-in stirring member 5. A heating plate 4 is provided below the grinding cup 2, and a brushless motor 6 is also provided below the heating plate 4. The brushless motor 6 includes a motor body 61 and a motor lower shell 62 provided on the outside of the bottom of the motor body 61. The motor lower shell 62 is fixedly connected to the heating plate 4 to fix the motor body 61 between the motor lower shell 62 and the heating plate 4. The top end of the motor shaft of the motor body 61 is fixedly connected to the stirring member 5.

[0049] The present application sets a heating plate 4 under the grinding cup 2, so that when the user needs to heat the ingredients in the grinding cup 2 when using the food processor to process ingredients, the user can control the heating plate 4 to generate heat to heat the ingredients in the grinding cup 2, thereby improving the temperature and taste of the output ingredients. At the same time, the heated ingredients are easier to stir and process, which helps to improve the processing efficiency of the ingredients and meet the user's needs.

[0050] At the same time, a brushless motor 6 is also provided below the heating plate 4. Due to the characteristics of the brushless motor 6, when the user uses the food processor to process food, the motor's rotational noise is lower, achieving a noise reduction effect. The brushless motor 6 can also achieve variable frequency control, allowing the food processor to control the brushless motor 6 to output different speeds according to different food ingredients and the processing process. This can achieve better and more complete processing of food ingredients, improving the taste of the finished food. Furthermore, the brushless motor 6 occupies a small space, which helps to improve the compactness of the entire machine's internal structure, reduce the space occupied by the food processor, and facilitate storage. Furthermore, compared to traditional brushed motors with the same output performance, the brushless motor 6's high power density can reduce the motor's weight by 30%. Even using high-grade rare earth magnets can reduce the weight by more than 40%, effectively reducing the weight of the entire machine, making it easier to handle and operate, and making it easier for users to move and clean the food processor, thereby improving the user experience.

[0051] Furthermore, the top end of the motor shaft of the motor body 61 is fixedly connected to the stirring member 5, so that the motor shaft can be directly connected to the stirring member 5 and thus directly drive the stirring member 5, eliminating the need for separate transmission components such as couplings, etc., which not only improves the transmission efficiency of the motor, but also reduces the noise generated by transmission collision or vibration between the components, and reduces the number of parts of the whole machine, making the internal structure more compact, and further reducing the weight of the whole machine, making it easier for users to pick up and operate. It should be noted that this application does not specifically limit the relative relationship between the brushless motor 6 and the crushing cup 2. It can be that the brushless motor 6 is arranged laterally relative to the crushing cup 2 in the axial direction, and the transmission of the motor shaft is achieved through transmission components such as gears, etc., which will not be repeated here.

[0052] In addition, the motor lower shell 62 is fixedly connected to the heating plate 4 to fix the motor body 61 between the motor lower shell 62 and the heating plate 4. On the one hand, it eliminates the need to arrange an outer shell outside the motor body 61 and then fix the entire motor in the base 3 through the motor bracket, which greatly simplifies the number of parts of the entire motor and the entire machine, and helps to further improve the compactness of the internal structure of the whole machine and further reduce the overall weight; on the other hand, compared with the traditional method of fixing the motor in the base 3 through the upper motor bracket and the lower motor bracket, the entire motor body 61 and the heating plate 4 can be fixed by only one motor lower shell 62, which further reduces the number of parts and at the same time compresses the axial height of the integrated assembly of the brushless motor 6 and the heating plate 4, thereby making the axial height of the whole machine lower and thinner, further reducing the occupied space of the food processor, and at the same time reducing the center of gravity height of the whole machine, making the food processor more stable when working.

[0053] It should be noted that the present application does not specifically limit the structure of the motor lower housing 62, which may be any one of the following embodiments:

[0054] Example 1: Figure 3 、 Figure 4 As shown, the motor body 61 includes a stator assembly 611 and a rotor assembly 612 rotatably disposed in the stator assembly 611 , and the motor lower shell 62 includes a bearing portion 621 abutting against the bottom end of the stator assembly 611 and a connecting portion 622 connected to the heating plate 4 .

[0055] Brushless motors in the prior art typically include an upper motor housing, a motor body, and a lower motor housing. The motor body includes a stator assembly and a rotor assembly. The brushless motors in the prior art clamp and secure the motor body together using the upper and lower motor housings, thereby fully positioning the motor body in the axial, radial, and circumferential directions. The motor is then hoisted and mounted on the heating plate. While this arrangement allows for reliable installation and positioning of the brushless motor, it is expensive to manufacture and assemble. The components of the upper and lower motor housings themselves are expensive, and the assembly process is complex. The brushless motor must first be assembled as a whole and then hoisted below the heating plate. This means that at least two assembly steps are required to achieve the desired installation and positioning of the brushless motor within the food processor.

[0056] The present application configures the motor lower shell 62 to include a bearing portion 621 abutting against the bottom end of the stator assembly 611 and a connecting portion 622 connected to the heating plate 4, so that the motor body is clamped and fixed between the motor lower shell and the heating plate, eliminating the need for a motor upper shell as in the prior art. This simplifies the accessories of the brushless motor, optimizes and reduces the installation process of the brushless motor in the food processor, greatly improves the installation efficiency of the brushless motor on the food processor, and significantly reduces the production and manufacturing cost of the food processor. Preferably, the entire motor body 61 is clamped and fixed between the bearing part 621 and the heating plate 4, which helps to improve the stability of the motor body 61, and the motor lower shell 62 does not need to limit the side wall of the stator assembly 611. It not only further simplifies the structure of the motor lower shell 62 and reduces its occupied space and weight, but also increases the heat dissipation area of ​​the motor body 61, improves the heat dissipation effect of the brushless motor 6, and avoids the situation where the motor lower shell 62 fully wraps the stator assembly 611, resulting in poor heat dissipation effect of the brushless motor 6, causing the brushless motor 6 to have a significant temperature rise, and the internal components are severely aged due to heat, which helps to extend the service life of components such as the brushless motor 6.

[0057] Furthermore, if Figure 3 、 Figure 4 As shown, the stator assembly 611 includes a stator coil and a stator shell. The outer wall of the stator shell is provided with a fixing portion 6111 aligned with the connecting portion 622. The food processor also includes a connecting piece, which passes through the connecting portion 622 and the fixing portion 6111 in sequence and is fixed to the heating plate 4.

[0058] By providing a fixing portion 6111 aligned with the connecting portion 622 on the outer wall of the stator housing, and the food processor also including a connecting piece, the connecting piece passes through the connecting portion 622 and the fixing portion 6111 in sequence and is fixed to the heating plate 4, so that the three components are fixedly connected after the connecting piece passes through the connecting portion 622 and the fixing portion 6111 and is fixed to the heating plate 4. On the one hand, after the connecting piece passes through the fixing portion 6111, the radial and circumferential limitation of the stator assembly 611 can be achieved, thereby improving the positional stability of the stator assembly 611 and the entire motor body 61, and avoiding the circumferential or radial movement of the stator assembly 611 during operation of the brushless motor 6, resulting in unstable rotation or even inability to work; on the other hand, one connecting piece can fix the stator housing, the motor body 61 and the heating plate 4, which helps to improve the coaxiality of the three, thereby ensuring the rotation stability of the brushless motor 6, and can improve assembly efficiency and shorten assembly time.

[0059] Specifically, if Figure 3 、 Figure 4As shown, the connecting portion 622 is a protrusion provided on the outer periphery of the bearing portion 621, and a through hole is provided on the protrusion. At the same time, the fixing portion 6111 is a protrusion provided on the outer wall of the stator shell and extending axially. A through hole is provided in the protrusion extending up and down. The heating plate 4 is provided with a downwardly extending mounting column, and a threaded hole is provided in the mounting column. The connecting piece is preferably a bolt, which passes through the through hole on the protrusion and the through hole on the protrusion in turn and is locked in the threaded hole to realize the fixed connection between the motor lower shell 62, the motor body 61 and the heating plate 4.

[0060] Example 2: Figure 5 、 Figure 6 As shown, in this embodiment, the motor body 61 includes a stator assembly 611 and a rotor assembly 612 rotatably disposed in the stator assembly 611 , and the motor lower shell 62 is a plastic package sealed around the outside of the stator assembly 611 .

[0061] By setting the motor lower shell 62 as a plastic package that is sealed and wrapped around the outside of the stator assembly 611, not only can the motor body 61 be fixed through the connection between the motor lower shell 62 and the heating plate 4, but the stator assembly 611 can also be sealed, so that the stator assembly 611 is not exposed. At the same time, the rotor assembly 612 has no live parts, so that the user can spray a small amount of water on the brushless motor 6 when cleaning the entire machine without causing internal insulation failure of the brushless motor 6, thereby improving the waterproofness of the brushless motor 6, protecting the brushless motor 6, improving product and user safety, and helping to extend the service life of the brushless motor 6.

[0062] Furthermore, if Figure 5 、 Figure 6 As shown, the stator coil in the stator assembly 611 is connected to the power line through the terminal 6112 , and the plastic package is provided with a through hole 623 for the terminal 6112 to pass through, and a sealing member is provided between the through hole 623 and the terminal 6112 .

[0063] By providing a through hole 623 for the terminal 6112 to pass through in the plastic package, and providing a seal between the through hole 623 and the terminal 6112, a seal is achieved between the through hole 623 and the terminal 6112, thereby preventing external cleaning water from flowing into the interior of the motor body 61, especially the stator coil, through the gap between the through hole 623 and the terminal 6112 when the user cleans the entire machine, thereby preventing the brushless motor 6 from short-circuiting or even being damaged. This further improves the waterproof performance of the brushless motor 6 and the protection of the brushless motor 6.

[0064] It should be noted that this application does not specifically limit the structure of the food processor. Figure 7 As shown, it can be provided with a mounting cavity in the main unit 1, and the grinding cup 2, the heating plate 4 and the brushless motor 6 are all accommodated in the mounting cavity. It can also be used as a preferred embodiment of the present application, such as Figure 2 As shown, the food processor also includes a base 3 connected to the bottom of the grinding cup 2 and detachably arranged on the main body 1. The main body 1 is provided with a control module 7 and a lower coupler electrically connected to the control module 7. The base 3 is also provided with an upper coupler electrically connected to the brushless motor 6 and the heating plate 4 and can be coupled with the lower coupler.

[0065] By providing a control module 7 within the main unit 1, the user can control the operation of the entire machine through the control module 7, thereby achieving control of the brushless motor 6 and the heating plate 4, meeting the user's usage needs. At the same time, compared with the traditional method of installing the control module 7 and other components on the base 3, the weight of the grinding cup 2 and the base 3 is further reduced, making it more convenient for the user to take the grinding cup 2. Moreover, when the user cleans the grinding cup 2, the cleaning water will not splash onto the control module 7, causing the control module 7 and other electrical components to become damp and short-circuit or even damage. This protects the control module 7 and helps to extend the service life of the entire machine.

[0066] Furthermore, if Figure 2 As shown, the main body 1 and the base 3 are further provided with a heat dissipation channel communicating with each other, and the food processor further includes a fan 8 provided in the heat dissipation channel.

[0067] Since the main unit 1 and the base 3 are provided with interconnected heat dissipation channels, and the food processor also includes a fan 8 arranged in the heat dissipation channel, when the food processor is in use, the fan 8 can drive the air flow in the heat dissipation channel, so that the external cold air passes into the heat dissipation channel, thereby achieving heat dissipation of the components in the heat dissipation channel, avoiding the situation where the internal components have poor heat dissipation effect and the temperature is too high for a long time, causing serious aging, which helps to extend the service life of each component.

[0068] Moreover, the heat dissipation channel in the main unit 1 is interconnected with the heat dissipation channel in the base 3, which greatly improves the heat dissipation efficiency. Preferably, only one fan 8 can be set in the heat dissipation channel to realize the flow of air in the heat dissipation channel and realize the overall heat dissipation of the entire food processor. Compared with the method of setting fans 8 in both the base 3 and the main unit 1, the number of parts is greatly simplified. One fan 8 can realize the heat dissipation of the entire machine, which helps to further reduce the weight of the entire machine and is convenient for users to take and store.

[0069] It should be noted that the present application does not specifically limit the configuration of the fan 8, which may be any one of the following embodiments:

[0070] Example 1: Figure 2 As shown, in this embodiment, the fan 8 is located in the base 3 and is drivingly connected to the bottom end of the motor shaft.

[0071] By setting the fan 8 to be located inside the base 3 and connected to the bottom end of the motor shaft, the brushless motor 6 can synchronously drive the fan 8 to rotate when working, thereby realizing the flow of air in the entire heat dissipation channel and achieving heat dissipation of various components. At the same time, the motor shaft directly drives the fan 8, eliminating the structure of a separate transmission component, which helps to improve the transmission efficiency of the fan 8, while further reducing the number of components and reducing the weight of the entire machine.

[0072] Embodiment 2: In this embodiment, the fan 8 is located in the main unit 1, the bottom end of the motor shaft is connected to an upper coupling, and the fan 8 is provided with a lower coupling that can be connected to the upper coupling.

[0073] By setting the fan 8 to be located inside the main unit 1, the bottom end of the motor shaft is connected to the upper coupling, and the fan 8 is provided with a lower coupling that can be connected to the upper coupling, so that when the crushing cup 2 and the base 3 are installed on the main unit 1, the upper coupling and the lower coupling are driven to cooperate to achieve a transmission connection, and the fan 8 is arranged inside the main unit 1, which further reduces the weight of the crushing cup 2 and the base 3, thereby further facilitating the user to take the crushing cup 2 and the base 3.

[0074] Example 3: In this example, the fan 8 is located in the host 1, and a driving motor for driving the fan 8 to rotate is also provided in the host 1.

[0075] By arranging the fan 8 to be located inside the main unit 1, and also providing a drive motor inside the main unit 1 to drive the fan 8 to rotate, the fan 8 is driven by a separate drive motor, eliminating the need for transmission components to achieve a transmission connection between the brushless motor 6 and the fan 8, further simplifying the components inside the grinding cup 2 and the base 3, and further reducing the weight of the grinding cup 2 and the base 3, making it easier to take the grinding cup 2 and the base 3.

[0076] As a preference under this embodiment, the heat dissipation channel has an air inlet and an air outlet, and the control module 7 is located on the side close to the air inlet so that the air flow passes through the control module 7 first and then passes through the brushless motor 6.

[0077] By providing the heat dissipation channel with an air inlet and an air outlet, and the control module 7 being located on the side close to the air inlet, so that the airflow first passes through the control module 7 and then passes through the brushless motor 6, the external cold air can first dissipate heat to the control module 7 after entering the heat dissipation channel, which helps to improve the heat dissipation effect of the airflow on the control module 7, can reduce the impact of excessive temperature on the control module 7, and reduce the risk of serious aging of electrical components in the control module 7 due to long-term high temperature, and avoid the airflow passing through other components such as the brushless motor 6 and then passing through the control module 7, causing the airflow temperature to rise and passing through the control module 7, resulting in poor heat dissipation effect of the airflow on the control module 7, so that the control module 7 is easily damaged due to excessive temperature.

[0078] It should be noted that the heat dissipation channel in this application is not limited to the above-mentioned setting. It can also be a separate heat dissipation channel set in the host 1 and the base 3. At the same time, a fan 8 connected to the motor shaft of the brushless motor 6 is set in the base 3, and a drive motor and a fan 8 connected to the drive motor are set in the host 1 to achieve separate heat dissipation of the host 1 and the entire machine, thereby improving the heat dissipation efficiency. At the same time, it eliminates the need to open a through hole in the host 1 to connect with the entire machine, thereby improving the sealing and waterproof performance of the host 1, making it easier for users to clean the host 1 and improving the user experience.

[0079] As a preferred embodiment of the present application, Figure 2 As shown, the grinding cup 2 is a through structure, and the heating plate 4 abuts against the bottom end of the grinding cup 2 to enclose the grinding cup 2 to form a grinding chamber.

[0080] By setting the grinding cup 2 as a top-to-bottom through structure, and the heating plate 4 abutting the bottom end of the grinding cup 2 to enclose the grinding cup 2 to form a grinding chamber, the setting of the bottom wall of the grinding cup 2 is eliminated, which not only helps to reduce the demoulding amount of the grinding cup 2, and thus reduces the weight of the grinding cup 2, thereby further reducing the weight of the whole machine and facilitating the taking of the whole machine, but also enables the heat generated by the heating plate 4 to be directly transferred to the food, which helps to improve the heat conduction effect and improve the heating efficiency.
