Abstract
Description
Technical Field
[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine. Background Technology
[0002] Most existing food processors have pressure relief holes in the lid. These holes maintain communication between the inside and outside of the machine during the high-speed rotation of the grinding blades and the high-temperature cooking of the soy milk, thus ensuring a pressure balance. Some pressure food processors use a sealed grinding chamber to pressure-cook the soy milk, improving its smooth texture. However, in existing pressure food processors, because the grinding chamber is sealed, a large amount of heat cannot escape during the grinding process. Excessive pressure in the grinding chamber can cause safety hazards such as the lid bulging and soy milk overflowing.
[0003] The applicant's earlier patent application, publication number CN113243784A, disclosed a splash-proof food processing machine, including a grinding cup and a lid body mounted on top of the grinding cup. The grinding cup and the lid body together form a sealed pulping chamber. The grinding cup is equipped with grinding blades for agitating materials. The food processing machine also includes a heat dissipation structure for cooling the grinding cup. During the process of the grinding blades agitating materials in the pulping chamber, the heat dissipation structure cools and reduces the pressure of the grinding cup.
[0004] However, although the above-mentioned solutions can cool the grinding cup to some extent with the help of the heat dissipation structure, the cooling time is too long, and the pressure relief effect of the heat dissipation structure on the grinding cup is not ideal. For example, when the heating element is cooking at full power, the cup body heats up very quickly, and the cup body also needs to be kept at a high temperature to cook soy milk. The gas in the grinding chamber expands rapidly, while the cooling speed of the heat dissipation structure is far slower than the gas expansion speed. The liquid in the grinding chamber evaporates continuously, and the replenishing gas pressure offsets the pressure relief effect of the heat dissipation structure. Therefore, although the existing heat dissipation structure has a certain cooling effect, the cooling speed is slow and it cannot achieve the effect of rapid cooling to quickly reduce pressure. The temperature inside the grinding chamber drops slowly, the pressure remains high for a long time, and there are still safety hazards such as overflow.
[0005] Some food processors now have pressure relief valves on the lid. When the pressure in the pot reaches a preset value, such as when it exceeds atmospheric pressure by 30 kPa, the pressure relief valve opens to release pressure. This pressure reduction occurs suddenly and rapidly, generating noise and hot steam, which brings a bad experience to the user. Utility Model Content
[0006] This invention provides a food processing machine that can pressure cook soybean milk, solving the problem of how to adjust the temperature of the pulping chamber more quickly to effectively release pressure, while avoiding the emission of hot steam to reduce safety hazards.
[0007] The technical solution adopted in this utility model is as follows:
[0008] This utility model provides a food processing machine, including a cup body and a cup lid that enclose a pulping chamber, a pulverizing device located inside the pulping chamber, and a heating element located outside the cup body. The food processing machine also includes a control device, a detection device connected to the control device, and a fan. The detection device extends into the pulping chamber to detect air pressure signals. The control device controls the fan to start and stop according to the signals from the detection device. A cover is provided on the outside of the cup body. The cover surrounds the outer periphery of the cup body and forms an annular pressure regulating air duct with the outer peripheral wall of the cup body. The cover has an air inlet and an air outlet. The fan includes a first fan located at the air inlet to draw outside air into the pressure regulating air duct and a second fan located at the air outlet to draw air out of the pressure regulating air duct.
[0009] The food processing machine provided by this utility model utilizes a first fan to draw outside air into the pressure regulating duct for air intake, and a second fan to draw air out of the pressure regulating duct for air exhaust. The first fan then draws air into the pressure regulating duct again to replenish the drawn air, thereby achieving airflow circulation and circulating cooling of the cup body. Therefore, it not only achieves faster temperature regulation of the cup body, but also reliably reduces the temperature and pressure of the pulping chamber, achieving the pressure regulation purpose of rapid pressure release in the pulping chamber. Specifically, cold outside air is powered by the first fan and enters the pressure regulating duct through the air inlet. Under the gathering and guiding effect of the pressure regulating duct, it moves along the outer wall of the cup, thus achieving rapid heat exchange with the cup. Powered by the second fan, the heat-exchanged hot air is discharged from the air outlet, realizing the circulating cooling of the cup. Due to the cooperation of the first and second fans, the heat of the cup can be quickly carried away by the circulating airflow in the pressure regulating duct, achieving rapid cooling. This allows the temperature of the pulping chamber to drop reliably, effectively releasing the pressure in the pulping chamber, achieving rapid depressurization, regulating the pressure in the pulping chamber, and avoiding safety issues such as cup lid bulging or pulp overflow. It does not require the discharge of hot steam through the cup lid pressure relief valve, making it safer to use.
[0010] In addition, the surrounding enclosure, which encloses the outer periphery of the cup and forms a ring-shaped pressure-regulating air duct with the outer wall of the cup, concentrates the cooling airflow and guides it along the outer wall of the cup, thereby improving the heat dissipation efficiency of the airflow. The food processing machine also includes a control device, a detection device connected to the control device, and a fan. The fan can be controlled by the control device and respond quickly according to the air pressure signal in the pulping chamber. At the same time, since the detection device can detect the pressure in the pulping chamber in real time, the fan can be started according to the actual pressure to regulate the pressure in the pulping chamber throughout the pulping stage of the food processing machine, instead of waiting for the pressure to reach the preset value as in the traditional pressure relief valve, which is usually opened for pressure relief after pulping is completed. Therefore, the pressure regulation time is more flexible, timely, and accurate, and the safety hazards of hot steam pressure relief are avoided.
[0011] In a preferred embodiment, the enclosure includes a first hood and a second hood, wherein the first hood and the second hood seal and clamp the cup body and are joined together to form the pressure regulating air duct.
[0012] The enclosure includes a first hood and a second hood, with the first and second hoods sealingly clamping the cup body and connecting to form the pressure regulating air duct. This not only ensures reliable fixation of the hoods and the cup body, making assembly convenient, labor-saving, and efficient, but also ensures that both the first and second hoods maintain a good seal with the outer peripheral wall of the cup body after assembly. This improves the sealing effect of the pressure regulating air duct, reduces airflow loss, and achieves efficient heat dissipation, allowing the airflow driven by the first and second fans to fully dissipate heat and cool the cup body, thereby achieving effective pressure relief.
[0013] In a preferred embodiment, the air inlet and air outlet are respectively provided on the first shroud and the second shroud, the first fan is fixed to the first shroud, and the second fan is fixed to the second shroud.
[0014] The first fan is fixed to the first fan cover, and the second fan is fixed to the second fan cover. The first fan and the first fan cover are assembled into a module, which is then assembled with the cup body, forming a modular assembly that improves assembly efficiency. Simultaneously, the independent fixing and installation of the first and second fans facilitates subsequent maintenance.
[0015] In a preferred embodiment, one end of the first shroud and the second shroud forms an air inlet, and the other end of the first shroud and the second shroud forms an air outlet. Both the first fan and the second fan are clamped and fixed by the ends of the first shroud and the second shroud.
[0016] By using one end of the first and second shrouds to form an air inlet and the other end to form an air outlet, and utilizing the naturally formed joint between the first and second shrouds to create the air inlet and outlet, the structural compactness is improved, and the need for separate air inlets and outlets is eliminated. This enhances the sealing effect of the pressure regulating duct and reduces airflow loss. Both the first and second fans are clamped and fixed by the ends of the first and second shrouds, eliminating the need for additional fixing and installation steps for the first and second fans, resulting in high assembly efficiency.
[0017] In a preferred embodiment, the outer wall of the cup body is provided with an upper ring edge and a lower ring edge that protrude radially outward. The top walls of the first and second wind hoods clamp the outer peripheral wall of the cup body and seal and press it against the upper ring edge along the axial direction. The bottom walls of the first and second wind hoods clamp the outer peripheral wall of the cup body and seal and press it against the lower ring edge along the axial direction.
[0018] By setting outwardly protruding upper and lower ring edges on the outer wall of the cup body, not only are the first and second wind hoods axially limited, ensuring a reliable fixed connection between the first and second wind hoods and the cup body, but they also form a sealing and pressing fit with the top and bottom walls of the first and second wind hoods, achieving a seal, improving the airtightness of the pressure regulating channel, and reducing airflow loss.
[0019] In a preferred embodiment, the outer wall of the cup body is fitted with an upper sealing ring and a lower sealing ring, the upper sealing ring is clamped between the top walls of the first and second air hoods, and the lower sealing ring is clamped between the bottom walls of the first and second air hoods.
[0020] By fitting an upper sealing ring and a lower sealing ring on the outer wall of the cup body, and clamping the upper and lower sealing rings between the first and second air hoods, the first and second air hoods can flexibly fit with the cup body, reducing assembly gaps, improving the airtightness of the pressure regulating channel, and reducing airflow loss.
[0021] In a preferred embodiment, the air inlet and the air outlet are arranged radially opposite to each other along the cup body.
[0022] The first fan draws airflow into the pressure regulating duct, which blows directly onto the cup body. The airflow then splits into two streams along the outer wall of the cup body before converging at the outlet. The second fan then provides the power to quickly expel the air. This split flow of cool air allows for thorough heat exchange between different parts of the cup body, achieving rapid cooling. Furthermore, the orderly airflow reduces mutual interference within the pressure regulating duct, accelerates air circulation, and improves gas flow efficiency and heat dissipation, thus achieving the purpose of pressure relief.
[0023] In a preferred embodiment, the enclosure includes a main body segment surrounding the cup body and a first extension segment and a second extension segment connected to both ends of the main body segment and extending along the tangential direction of the main body segment. The first extension segment and the second extension segment are arranged rotationally symmetrically around the center of the cup body, and the air inlet and air outlet are located at the ends of the first extension segment and the second extension segment, respectively.
[0024] By setting the enclosure as a main body segment, a first extension segment and a second extension segment extending along the tangential direction of the main body segment, with the air inlet and outlet located at the ends of the first extension segment and the second extension segment, the airflow flows in from the air inlet along a direction tangential to the peripheral wall of the cup body, circles the cup body once, and then exits from the air outlet along a direction tangential to the peripheral wall of the cup body. This improves the airflow guidance effect, reduces the interference of airflow from different directions, reduces airflow loss, achieves efficient cooling, and achieves the purpose of pressure relief.
[0025] In a preferred embodiment, the cup body is an aluminum-based cup body, and the aluminum-based cup body is integrally formed with outwardly protruding heat dissipation fins that extend circumferentially along the cup body.
[0026] The aluminum-based cup body is integrally formed with outward-protruding heat dissipation fins that extend along the circumference of the cup body, which improves the heat dissipation effect of the cup body. The heat dissipation fins increase the contact area between the cup body and the airflow in the pressure regulating duct, thereby improving the cooling effect and achieving the purpose of depressurization of the pulping chamber.
[0027] In a preferred embodiment, the heat dissipation fins abut against the inner wall of the enclosure to divide the pressure regulating air duct into multiple annular flow channels; or, the inner wall of the enclosure is provided with baffles that mate with the heat dissipation fins, and the heat dissipation fins and the baffles together divide the pressure regulating air duct into multiple annular flow channels.
[0028] By dividing the pressure regulating air duct into multiple annular flow channels through heat dissipation fins, the airflow within the pressure regulating channel is divided into multiple parallel streams, allowing for more thorough contact between the airflow and the heat dissipation fins. This enhances the cooling effect per unit time, resulting in rapid cooling and achieving the purpose of depressurizing the pulping chamber.
[0029] In a preferred embodiment, the food processing machine further includes a housing fitted over the cup body and the cover, the housing being provided with grid holes corresponding to the air inlet and the air outlet;
[0030] By setting grid holes in the casing, the airflow is filtered at the air inlet to prevent particulate matter from entering the pressure regulating air duct and causing blockage, thus ensuring the circulation of airflow; the grid holes at the air outlet prevent the airflow from being discharged directly, reducing the noise of the air outlet.
[0031] In a preferred embodiment, the detection device includes a pressure sensor disposed on the cup lid or cup body to detect the steam pressure inside the cup and obtain a pressure signal; or, the detection device includes a temperature sensor disposed through the cup wall to detect the liquid temperature inside the cup and obtain a pressure signal.
[0032] By incorporating a pressure sensor, the steam pressure inside the cup is directly detected, providing direct and accurate measurement. Furthermore, a temperature sensor is used to detect the liquid temperature inside the cup, while simultaneously indirectly detecting the pressure within the cup, thus integrating these functions.

[0048] like Figure 1-4 As shown, in one embodiment, this utility model provides a food processing machine, including a cup body 10 and a cup lid 20 that enclose a pulping chamber, a pulverizing device 30 located inside the pulping chamber, a heating element 40 located outside the cup body 10, and a motor 50 for driving the pulverizing device 30. The pulverizing device 30 is a pulverizing blade, or the pulverizing device 30 includes a moving grinding head and a stationary grinding head. The food processing machine also includes a control device 60, a detection device 70 connected to the control device 60, and a fan. The detection device 70 extends into the pulping chamber to detect air pressure signals. The control device 60 controls the fan to start and stop according to the signals from the detection device 70. A cover 80 is provided on the outside of the cup body 10. The cover 80 surrounds the outer periphery of the cup body 10 and forms an annular pressure regulating air duct 800 with the outer peripheral wall of the cup body 10. The cover 80 has an air inlet 801 and an air outlet 802. Figure 1 As shown, the fan includes a first fan 91 located at the air inlet 801 to draw outside air into the pressure regulating duct and a second fan 92 located at the air outlet 802 to draw air out of the pressure regulating duct to the outside.
[0049] The food processing machine provided by this utility model utilizes a surrounding enclosure 80 that encloses the outer periphery of the cup body 10 and forms an annular pressure regulating air duct 800 with the outer peripheral wall of the cup body 10. This can concentrate the cooling airflow and guide the airflow along the outer wall of the cup body 10 to improve the heat dissipation efficiency of the airflow on the cup body 10. The food processing machine also includes a control device 60, a detection device 70 connected to the control device 60, and a fan. The fan can be controlled by the control device 60 and respond quickly according to the air pressure signal in the pulping chamber. At the same time, since the detection device 70 can detect the pressure in the pulping chamber in real time, the fan can be started according to the actual pressure to regulate the pressure in the pulping chamber throughout the pulping stage of the food processing machine, instead of having to wait for the pressure to reach the preset value like a traditional pressure relief valve, which is usually opened for pressure relief after pulping is completed. Therefore, the timing of pressure regulation is more flexible, timely, and accurate. The first fan 91 draws air into the pressure regulating duct 800, and the second fan 92 exhausts air to the outside. The first fan 91 then draws air into the pressure regulating duct 800 again to replenish the airflow, thereby achieving the purpose of circulating cooling of the cup body 10. This not only achieves temperature regulation of the cup body 10, but also reliably reduces the temperature and pressure of the pulping chamber, achieving the purpose of rapid pressure release in the pulping chamber. Specifically, cold outside air is powered by the first fan 91 and enters the pressure regulating duct 800 through the air inlet 801. Under the gathering and guiding effect of the pressure regulating duct 800, the air moves along the outer wall of the cup body 10, thereby achieving rapid heat exchange with the cup body 10. Powered by the second fan 92, the hot air that has undergone heat exchange is discharged from the air outlet 802, realizing the circulating cooling of the cup body 10. Due to the cooperation of the first fan 91 and the second fan 92, the heat of the cup body 10 can be quickly carried away by the circulating airflow in the pressure regulating duct 800, achieving the purpose of rapid cooling. This allows the temperature of the pulping chamber to drop reliably, effectively releasing the pressure in the pulping chamber, achieving rapid pressure relief, regulating the pressure in the pulping chamber, and avoiding safety issues such as the cup lid 20 bulging or overflowing, making it safer to use.
[0050] Since the first and second fans effectively cool and depressurize the cup, the traditional pressure relief valve method can be eliminated, preventing the release of hot steam and improving safety. Of course, this invention can also use the first and second fans to cool the liquid inside the cup, reducing user waiting time and improving the user experience.
[0051] This invention does not limit the specific structure of the detection device 70. For example, the detection device 70 includes a pressure sensor, which is disposed on the cup lid 20 or the cup body 10 to detect the steam pressure inside the cup body 10; or, the detection device 70 includes a temperature sensor, such as... Figure 1As shown, a temperature sensor is installed through the cup wall of the cup body 10 to obtain a pressure signal by detecting the liquid temperature inside the cup body 10. By setting up a pressure sensor, the steam pressure inside the cup body 10 is directly detected, providing direct and accurate detection. By using a temperature sensor, the liquid temperature inside the cup body 10 can be detected, while the pressure inside the cup body 10 can be detected indirectly, achieving functional integration.
[0052] More specifically, such as Figure 4 As shown, the detection device 70 includes a first temperature sensor 71, a second temperature sensor 72 with a setting higher than the first temperature sensor, a fuse 73, and a temperature controller 74, so that it can flexibly cool down and depressurize according to the gas pressure signal inside the cup during the entire soy milk preparation stage, and can also heat up and pressurize to achieve sensitive and accurate pressure adjustment.
[0053] Based on the positive correlation between pressure and temperature within the sealed pulping chamber—specifically, after boiling water to 100℃, the pressure increases by 4-5 kPa for every 1℃ increase—and considering the presence of a first and second temperature sensor monitoring the temperature within the pulping chamber, the pressure is maintained by using the resistance of the temperature sensors in conjunction with the heating element. For example, when the pressure inside the pulping chamber reaches 30 kPa above atmospheric pressure, the first and second fans are activated to release pressure. Using two temperature sensors provides more accurate feedback on the temperature and pressure values within the pulping chamber.
[0054] This utility model does not limit the structure of the cover or the way it is fixed to the cup body. For example:
[0055] Implementation Example 1, such as Figure 1-4 As shown, the enclosure 80 includes a first hood 81 and a second hood 82. The first hood 81 and the second hood 82 seal and clamp the cup body 10 and are connected to form a pressure regulating air duct 800.
[0056] The enclosure 80 includes a first hood 81 and a second hood 82. The first hood 81 and the second hood 82 seal and clamp the cup body 10 and are connected to form a pressure regulating air duct 800. This not only ensures reliable fixation of the hood and the cup body 10, but also makes assembly convenient, labor-saving and efficient. At the same time, after assembly, the first hood 81 and the second hood 82 can maintain a good seal with the outer peripheral wall of the cup body 10, thereby improving the sealing effect of the pressure regulating air duct 800, reducing airflow loss, and achieving efficient heat dissipation. This allows the airflow driven by the first fan 91 and the second fan 92 to fully dissipate heat and cool the cup body 10, thereby achieving effective pressure relief.
[0057] In this embodiment, the first shroud 81 and the second shroud 82 can be fixed by a snap-fit 83, or they can be fixed by screws or other means.
[0058] like Figure 2 As shown, more preferably, the air inlet 801 and the air outlet 802 are respectively opened on the first shroud 81 and the second shroud 82, the first fan 91 is fixed to the first shroud 81, and the second fan 92 is fixed to the second shroud 82.
[0059] More specifically, both the first fan 91 and the second fan 92 are fixed by screws 93. A first mounting groove that is recessed from the outside to the inside is provided on the first fan cover 81, and the first fan 91 is fixed to the first mounting groove; a second mounting groove that is recessed from the outside to the inside is provided on the second fan cover, and the second fan 92 is fixed to the second mounting groove.
[0060] The first fan 91 is fixed to the first fan cover 81, and the second fan 92 is fixed to the second fan cover 82. The first fan 91 and the first fan cover 81 are assembled into a module, which is then assembled with the cup body 10, forming a modular assembly and improving assembly efficiency. At the same time, the independent fixing and installation of the first fan 91 and the second fan 92 facilitates subsequent maintenance.
[0061] like Figure 3 , 4 As shown in this embodiment, the outer wall of the cup body 10 is provided with an upper ring edge 101 and a lower ring edge 102 that protrude radially outward. The top walls of the first wind shield 81 and the second wind shield 82 clamp the outer peripheral wall of the cup body 10 and seal and press it against the upper ring edge 101 along the axial direction. The bottom walls of the first wind shield 81 and the second wind shield 82 clamp the outer peripheral wall of the cup body 10 and seal and press it against the lower ring edge 102 along the axial direction.
[0062] By providing an outwardly protruding upper ring edge 101 and lower ring edge 102 on the outer wall of the cup body 10, not only are the first wind cover 81 and the second wind cover 82 axially limited, so that the first wind cover 81 and the second wind cover 82 are reliably fixedly connected to the cup body 10, but also the top and bottom walls of the first wind cover 81 and the second wind cover 82 are sealed and pressed together to achieve sealing, improve the airtightness of the pressure regulating channel, and reduce airflow loss.
[0063] Preferably, the upper ring edge 101 and lower ring edge 102 can be heat dissipation fins integral with the cup body 10, wherein the cup body 10 is an aluminum-based cup body 10. More preferably, the heat dissipation fins abut against the inner wall of the enclosure 80 to divide the pressure regulating air duct 800 into multiple annular flow channels; or, the inner wall of the enclosure 80 is provided with baffles that connect with the heat dissipation fins, and the heat dissipation fins and baffles together divide the pressure regulating air duct 800 into multiple annular flow channels.
[0064] An aluminum-based cup body 10 is integrally formed with outwardly protruding heat dissipation fins extending circumferentially along the cup body 10. This improves the heat dissipation effect of the cup body 10. The heat dissipation fins increase the contact area between the cup body 10 and the airflow within the pressure regulating duct 800, thereby improving the cooling effect and achieving the purpose of depressurizing the pulping chamber. The heat dissipation fins divide the pressure regulating duct 800 into multiple annular flow channels, causing the airflow within the pressure regulating channels to be divided into parallel multiple streams. This allows for more thorough contact between the airflow and the heat dissipation fins, increasing the cooling effect per unit time and achieving rapid cooling, thus achieving the purpose of depressurizing the pulping chamber.
[0065] In this embodiment, the heat dissipation fins 100 not only expand the heat dissipation area but also serve to axially limit the first and second shrouds 81 and 82. It is understood that the aforementioned upper and lower ring edges 101 and 102 can also be applied to other cup bodies, solely for axial limiting of the enclosure.
[0066] Of course, to further improve the sealing effect, sealing rings can be set at the upper ring edge 101 and the lower ring edge 102 respectively, so that the top walls of the first wind cover 81 and the second wind cover 82 clamp the first sealing ring with the upper ring edge 101; or, the bottom walls of the first wind cover 81 and the second wind cover 82 clamp the second sealing ring with the lower ring edge 102.
[0067] like Figure 2 , 3 As shown, preferably, the air inlet 801 and the air outlet 802 are arranged radially opposite each other along the cup body 10.
[0068] The first fan 91 draws airflow into the pressure regulating duct 800. The airflow blows directly onto the cup body 10, and finally splits into two streams along the outer periphery of the cup body 10, converging at the air outlet 802, where the second fan 92 continues to provide power for rapid discharge. The split cold airflow can fully exchange heat with different parts of the cup body 10, achieving rapid cooling. Moreover, the orderly airflow reduces mutual interference of airflow within the pressure regulating duct 800, accelerates airflow circulation, improves gas flow efficiency, and enhances heat dissipation efficiency, thereby achieving the purpose of pressure relief.
[0069] Of course, in addition to the method of this embodiment, the fixing of the first shroud 81 and the second shroud 82 can also be configured such that one end of the first shroud 81 and the second shroud 82 forms an air inlet 801, and the other end of the first shroud 81 and the second shroud 82 forms an air outlet 802, and the first fan 91 and the second fan 92 are both clamped and fixed by the ends of the first shroud 81 and the second shroud 82.
[0070] By using one end of the first shroud 81 and the second shroud 82 to form an air inlet 801, and the other end of the first shroud 81 and the second shroud 82 to form an air outlet 802, the air inlet 801 and the air outlet 802 are formed by the naturally formed mating seam of the first shroud 81 and the second shroud 82. This improves the structural compactness and eliminates the need for separate air inlets 801 and outlets 802, thereby improving the sealing effect of the pressure regulating duct 800 and reducing airflow loss. Both the first fan 91 and the second fan 92 are clamped and fixed by the ends of the first shroud 81 and the second shroud 82, eliminating the need for additional fixing and installation steps for the first fan 91 and the second fan 92, resulting in high assembly efficiency.
[0071] In this embodiment, the food processor also includes a housing 11 fitted over the cup body 10 and the enclosure 80, the housing 11 having grid holes 110 corresponding to the air inlet 801 and the air outlet 802. Figure 2 As shown, the food processing machine also includes a water tank 12 that supplies water to the cup body. The water tank is installed on the rear side of the cup body, the control device is installed on the front side of the cup body, and the air inlet 801 and air outlet 802 are located on the left and right sides of the cup body.
[0072] By setting a grid hole in the casing, the airflow is filtered at the air inlet 801 to prevent particulate matter from entering the pressure regulating air duct 800 and causing blockage, thus ensuring the circulation of airflow; the grid hole is at the air outlet 802 to prevent the airflow from being discharged directly and reduce the noise of the air outlet.
[0073] Of course, in other embodiments of this utility model, the enclosure 80 is integrally formed into the casing of the food processing machine.
[0074] Implementation Example 2, such as Figure 5 , 6 As shown in Figure 7, the difference between this embodiment and embodiment 1 is the sealing and fitting method between the cover and the cup body.
[0075] In this embodiment, the outer wall of the cup body 10 is fitted with an upper sealing ring 13 and a lower sealing ring 14. The top walls of the first air hood 81 and the second air hood 82 are fitted with the upper sealing ring 13, and the bottom walls of the first air hood 81 and the second air hood 82 are fitted with the lower sealing ring 14.
[0076] By providing an upper sealing ring 13 and a lower sealing ring 14 on the outer wall of the cup body 10, and clamping the upper and lower sealing rings on the first air shroud 81 and the second air shroud 82, the first air shroud 81 and the second air shroud 82 are flexibly fitted with the cup body 10, reducing assembly gaps, improving the airtightness of the pressure regulating channel, and reducing airflow loss.
[0077] In addition, as a more preferred embodiment of this example or other examples, a pressure relief hole and a pressure relief valve 15 are provided in the cup lid. When the pressure inside the cup reaches the preset pressure, the pressure relief valve opens the pressure relief hole. Therefore, the pressure regulating air duct is used to achieve the first pressure relief protection for the cup body, and the pressure relief valve is used to achieve the second pressure relief protection for the cup body, thereby improving the safety of use.
[0078] Implementation Example 3, such as Figure 8 As shown, this implementation example differs from implementation example 1 in the enclosure structure and the location of the air inlet and outlet.
[0079] The enclosure 80 includes a main body segment 86 surrounding the cup body 10 and a first extension segment 84 and a second extension segment 85 connected to both ends of the main body segment and extending along the tangential direction of the main body segment. The first extension segment and the second extension segment are arranged symmetrically around the center of the cup body 10. The air inlet 801 and the air outlet 802 are located at the ends of the first extension segment and the second extension segment, respectively.
[0080] By setting the enclosure 80 as the main body section, and the first extension section and the second extension section extending along the tangential direction of the main body section, the air inlet 801 and the air outlet 802 are located at the ends of the first extension section and the second extension section. Therefore, the airflow flows in from the air inlet 801 along the direction tangential to the peripheral wall of the cup body 10, surrounds the cup body 10 once, and then exits from the air outlet 802 along the direction tangential to the peripheral wall of the cup body 10. This improves the airflow guidance effect, reduces the interference of airflow in different directions, reduces airflow loss, achieves efficient cooling, and achieves the purpose of pressure relief.
[0081] Example 4: In this example, the enclosure is an integral structure that surrounds the cup.
[0082] Optionally, a buffer ring is provided on the outer wall of the cup body, and the cover is fitted around the outer periphery of the cup body along the axial direction of the cup body and abuts against the buffer ring.

[0084] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
