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] Patent CN113273907A discloses a food processing machine and its control method. The control method includes: when entering the grinding stage, controlling a solenoid valve to close the venting channel; when the grinding stage ends, controlling the solenoid valve to open the venting channel, thereby achieving a semi-sealed grinding cup slurry preparation scheme and preventing overflow during slurry preparation. A pressure sensor is installed inside the venting channel. During motor operation, the pressure sensor detects the pressure inside the venting channel in real time, and controls the motor to operate or stop based on pressure changes. This ensures that the pressure in the grinding chamber is not excessive, and that the pressure in the grinding cup is low when the venting channel is opened, preventing slurry from being discharged from the venting channel due to excessive air pressure when the venting valve is opened.

[0003] However, the venting channel consists of a solenoid valve and tubing, which is typically flexible. When the solenoid valve opens the venting channel, the gas flowing through the tubing causes it to vibrate or oscillate. This causes the pressure sensor, fixed to the tubing, to oscillate as well. This mechanical vibration and oscillation are directly transmitted to the sensing element inside the sensor. The vibration force may be superimposed on the normal detection pressure of the sensing element. Furthermore, the deformation of the sensing elements, such as piezoresistive chips and capacitive diaphragms, during the vibration of the pressure sensor leads to a deviation between the detected pressure value and the actual pressure value, reducing detection accuracy. Moreover, the installation space in the main housing of the food processor is limited, so the pressure sensor is very close to the grinding cup and the main housing. The heat from the grinding cup's cooking process is directly transferred to the pressure sensor. The characteristics of the sensing elements, such as piezoresistive chips and capacitive diaphragms, change with increasing temperature. Additionally, the gas pressure passing through the pressure sensor is affected by the temperature of the grinding cup and cannot remain stable, causing fluctuations in the pressure sensor's detection results, deviating from the true pressure value and resulting in poor detection accuracy.

[0004] In addition, when the pressure sensor wobbles due to the vibration of the pipeline, it will collide with the crushing cup and the main unit housing, generating collision noise, increasing the overall operating noise of the machine, and the pressure sensor is easily damaged. Utility Model Content

[0005] This invention provides a food processing machine to solve the technical problems in the prior art where the pressure sensor is only directly fixed to the pipeline, causing the pressure sensor to undergo mechanical vibration with the pipeline and be directly affected by the heat interference of the grinding cup, resulting in poor detection accuracy and high vibration noise.

[0006] The technical solution adopted by this utility model is as follows: This utility model provides a food processing machine, including a main housing, a grinding cup installed in the main housing, a pipeline, and a pressure sensor. One end of the pipeline is connected to the inner cavity of the grinding cup, and the other end is connected to a control valve. The pipeline has an installation port located between the control valve and the grinding cup. The pressure sensor is installed in the installation port. The main housing is also provided with a mounting bracket connected to the grinding cup. The pressure sensor is fixed to the mounting bracket, and the mounting bracket isolates the pressure sensor from the grinding cup.

[0007] The food processing machine provided by this utility model fixes a pressure sensor to a mounting bracket connected to the grinding cup, thus isolating the pressure sensor from the grinding cup. The mounting bracket itself has a certain structural rigidity, resisting mechanical vibration. Compared to the pressure sensor being directly fixed to the pipeline, the mounting bracket can buffer and overcome minor vibrations transmitted from the pipeline, avoiding vibration deformation and detection errors of the pressure sensor's detection element, resulting in more accurate and sensitive detection. It also reduces the probability of pressure sensor oscillation and collision, reducing collision noise and enabling the food processing machine to operate with low noise. Furthermore, the mounting bracket isolates heat from the grinding cup, reducing heat transfer to the pressure sensor during the grinding process. Therefore, with its dual functions of vibration resistance and heat insulation, the mounting bracket allows the pressure sensor to escape mechanical interference from pipeline vibration and reduces the impact of high temperatures generated during grinding, resulting in a stable working environment and effectively improving the accuracy and sensitivity of pressure detection.

[0008] In a preferred embodiment, the mounting bracket is a mounting cover surrounding the pulverizing cup, and the pressure sensor is fixed to the outer wall of the mounting cover.

[0009] The mounting bracket is designed as a mounting cover surrounding the outer perimeter of the grinding cup, and the pressure sensor is fixed to the outer wall of the mounting cover. The mounting cover provides a stable installation for the pressure sensor to block the transmission of pipeline vibration, while also isolating the heat of the grinding cup in all directions. It can also integrate the functions of heat preservation and sound insulation of the grinding cup, realizing functional integration. There is no need to set up an additional special pressure sensor fixing structure, simplifying the structure of the food processor and making efficient use of the limited installation space of the main unit housing, resulting in a compact structure.

[0010] In a preferred embodiment, the mounting cover is sealed to the outer wall of the grinding cup to form a cooling channel, through which a cooling medium is introduced to cool the grinding cup.

[0011] By sealing the outer wall of the grinding cup with the mounting cover to form a cooling channel, not only is the grinding cup cooled, but the distance between the mounting cover and the grinding cup is also increased. Combined with the isolation provided by the mounting cover structure itself, the pressure sensor is further removed from the grinding cup, free from interference from the heat of the grinding cup, thus improving detection accuracy. The sealed cooling channel ensures the orderly flow of the cooling medium within it. For example, introducing water or air into the cooling channel prevents leakage or loss of the cooling medium, effectively removing the heat generated by the grinding cup during processing and quickly lowering its temperature. On one hand, after the soy milk is cooked, the cooling medium cools the grinding cup, achieving rapid cooling of the soy milk for immediate consumption and reducing waiting time. On the other hand, when the pressure sensor detects that the pressure in the grinding cup exceeds a preset value, the cooling medium cools the cup, achieving rapid pressure reduction and improving safety.

[0012] In a preferred embodiment, the mounting bracket includes a first bracket and a second bracket, which are arranged sequentially along the circumference of the crushing cup and spliced ​​together as a whole.

[0013] By combining the first and second brackets separately into a single integrated mounting bracket, the assembly process allows for initial positioning of the first and second brackets on their respective outer circumferences of the grinding cup. These brackets are then joined together to form the complete mounting bracket, eliminating the need for a complete, all-over installation of the grinding cup. This simplifies the installation process and improves assembly convenience and efficiency. Furthermore, the integrated mounting bracket, with the first and second brackets joined circumferentially around the grinding cup, effectively isolates heat from the cup, preventing heat interference with the pressure sensor and improving its accuracy. The first and second brackets are independently designed, allowing the pressure sensor to be mounted on either one. This simple installation structure facilitates easy disassembly and maintenance.

[0014] In a preferred embodiment, the mounting bracket is a support for holding the pulverizing cup. The support is provided with a mounting part for mounting the pressure sensor, which isolates the pressure sensor from the pulverizing cup. The support separates a motor mounting cavity with a top opening and an assembly cavity with a side opening. The motor mounting cavity accommodates a motor. The main housing is provided with an assembly port communicating with the side opening of the assembly cavity. The assembly cavity accommodates a liquid receiving container.

[0015] The mounting bracket serves as a support base, which not only bears the load of the grinding cup but also secures and isolates the pressure sensor via the mounting section. This eliminates the need for an additional mounting bracket, simplifying the internal structure of the equipment. The mounting section isolates the pressure sensor from the grinding cup, effectively blocking heat transfer from the grinding cup and interference from pipeline vibrations, ensuring accurate pressure detection. The top-opening motor mounting cavity separated by the support base facilitates the housing and installation of the motor, while the side-opening assembly cavity, combined with the assembly port of the main housing, allows for convenient removal and placement of the liquid receiving container from the side. This achieves a rational layout of the grinding cup, motor, and liquid receiving container, making full use of the internal space of the main housing. The compact structure reduces the overall size of the machine and minimizes its footprint.

[0016] In a preferred embodiment, the pulverizing cup includes a cup body and a cup lid, the cup lid has a communication opening, the pipeline includes a first tube located in the cup lid and a second tube located inside the main housing, the main housing is provided with a coupling bracket for installing a coupling connector, the second tube and the first tube are connected through the coupling connector, and the mounting bracket is the coupling bracket.

[0017] By setting a connecting port in the cup lid, the port is positioned higher, reducing the risk of slurry overflowing from the port due to heat during pulping, and also reducing the probability of slurry residue clogging the port. This ensures smooth pressure relief and media supply to the pulverizing cup, resulting in a reliable structure. The mounting bracket is the aforementioned coupling bracket, thus achieving functional integration. It integrates the coupling connection between the first and second pipe bodies, while also fixing and isolating the pressure sensor. No additional mounting bracket is needed, simplifying the internal structure of the equipment.

[0018] In a preferred embodiment, the grinding cup is provided with a drain valve, and the food processor further includes a receiving container located below the drain valve. The control valve is a pressure relief valve, which has an outlet facing the receiving container, allowing the grinding cup to communicate with the receiving container through the pipeline.

[0019] By setting the control valve as a pressure relief valve and the pipeline as a pressure relief pipeline, the pressure relief requirements of the grinding cup are met. High pressure in the grinding cup is quickly released, avoiding safety hazards caused by excessive pressure and ensuring safe use. A pressure sensor is installed at the pipeline's installation port to directly detect the air pressure discharged from the grinding cup. The detection is accurate, direct, sensitive, and reliable. The food processor can control the motor's operation and the opening and closing of the pressure relief valve based on the accurate air pressure detected by the pressure sensor. The pressure relief valve has an outlet facing the liquid receiving container, allowing the grinding cup to connect to the liquid receiving container through the pipeline. This allows high-temperature steam from the grinding cup or condensate from the steam in the pipeline to be discharged into the liquid receiving container, preventing steam burns to the user and preventing condensate from dripping onto the work surface, making it safer and more convenient to use.

[0020] In a preferred embodiment, the food processor further includes a supply device installed in the main housing, the grinding cup being connected to the supply device via the pipeline, and the control valve being a water pump, an air pump, or a check valve.

[0021] The grinding cup is connected to the supply device via the pipeline. The supply device provides water or air to the grinding cup, achieving a self-cleaning effect for the food processor. Furthermore, the air supply can also be used to dry the grinding cup, keeping it dry and hygienic. The control valve is a water pump, air pump, or check valve. Correspondingly, a pressure sensor is installed at the pipeline inlet. After the control valve is closed, the air pressure inside the grinding cup can be detected, and the motor can be controlled based on the air pressure in the grinding cup.

[0022] In a preferred embodiment, the food processing machine further includes a liquid receiving container and a supply device. The pipeline includes a first pipeline communicating with the liquid receiving container, a second pipeline communicating with the supply device, and a tee connector. The tee connector has a first connector communicating with the first pipeline, a second connector communicating with the second pipeline, and a third connector communicating with the inner cavity of the grinding cup. The mounting port and the control valve are both located in the first pipeline or the second pipeline.

[0023] By using a three-way connector, the flow paths between the liquid receiving container, supply device, and pulverizing cup can be switched and integrated, eliminating the need for separate pipelines for each different structure. This simplifies the internal piping layout and saves installation space within the main unit housing. Depending on actual needs, the mounting port for the pressure sensor and the control valve can both be located in the first or second pipeline, allowing for flexible pressure sensor installation. Regardless of which pipeline the pressure sensor is installed in, mechanical vibration damping and heat insulation can be provided through mounting brackets, improving the detection accuracy of the pressure sensor.

[0024] In a preferred embodiment, the pressure sensor is provided with a threaded section, and the mounting port is threadedly connected to the threaded section.

[0025] The pressure sensor and the mounting port are connected by threads, which not only ensures the reliable fixation of the pressure sensor to the pipeline, enabling the pressure sensor to reliably detect the flow pressure in the pipeline and realize the detection of the air pressure in the crushing cup, but also allows for flexible installation and removal of the pressure sensor, facilitating the maintenance and replacement of the pressure sensor.

[0026] In a preferred embodiment, the mounting bracket is provided with a limiting groove whose opening is away from the crushing cup, and the pressure sensor is fixed in the limiting groove.

[0027] The mounting bracket is equipped with a limiting groove that is far away from the grinding cup. The limiting groove provides a stable mounting position for the pressure sensor, preventing the sensor from shifting or loosening during equipment operation. The limiting groove also effectively isolates the heat from the grinding cup, ensuring the accuracy of the pressure sensor detection and improving the convenience and stability of the pressure sensor installation.

[0028] In a preferred embodiment, the mounting bracket is provided with a snap fastener, and the pressure sensor is snapped onto the mounting bracket via the snap fastener.

[0029] The mounting bracket features snap-fit ​​fasteners that directly attach the pressure sensor to the bracket, eliminating the need for additional fastening tools or connectors. This allows for quick installation and removal of the pressure sensor, significantly simplifying the equipment assembly process and simplifying sensor replacement or repair during later maintenance, thus improving assembly and maintenance efficiency. The snap-fit ​​fasteners securely fix the pressure sensor to the mounting bracket, and the bracket's isolation between the pressure sensor and the crushing cup effectively prevents the pressure sensor from loosening or shifting due to pipeline mechanical vibration, ensuring stable pressure sensor detection position, consistent detection performance, and improved detection accuracy.

[0033] Many specific details are set forth in the following description to provide a full understanding of the present invention.

Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0037] like Figure 1 As shown, in one embodiment, this utility model provides a food processor, including a main housing 10, a grinding cup 20 installed inside the main housing 10, a pipeline 30, and a pressure sensor 40. One end of the pipeline 30 is connected to the inner cavity of the grinding cup 20, and the other end is connected to a control valve 50. The pipeline 30 has an installation port 301 located between the control valve 50 and the grinding cup 20, and the pressure sensor 40 is installed in the installation port 301. Figure 2 As shown, the main housing 10 is also provided with a mounting bracket 60 connected to the grinding cup 20. The pressure sensor 40 is fixed to the mounting bracket 60, and the mounting bracket 60 isolates the pressure sensor 40 from the grinding cup 20.

[0038] It should be explained that the mounting bracket 60 isolates the pressure sensor 40 from the grinding cup 20, that is, it is placed between the pressure sensor 40 and the grinding cup 20.

[0039] The food processing machine provided by this utility model fixes the pressure sensor 40 to the mounting bracket 60 connected to the grinding cup 20, and uses the mounting bracket 60 to isolate the pressure sensor 40 from the grinding cup 20. The mounting bracket 60 itself has a certain structural rigidity, which plays a role in resisting mechanical vibration. Compared with the pressure sensor 40 being directly fixed to the pipeline 30, the mounting bracket 60 can buffer and overcome the small vibrations transmitted from the pipeline 30, avoiding vibration deformation and detection errors of the detection element of the pressure sensor 40, resulting in more accurate and sensitive detection. It also reduces the probability of swaying and collision of the pressure sensor 40, reducing collision noise, and enabling the food processing machine to operate with low noise. In addition, the mounting bracket 60 isolates the heat of the grinding cup 20, reducing the transfer of heat to the pressure sensor 40 when the grinding cup 20 is boiling. Therefore, under the dual functions of vibration resistance and heat insulation, the mounting bracket 60 enables the pressure sensor 40 to not only get rid of the mechanical interference caused by the vibration of the pipeline 30, but also reduce the impact of the high temperature generated by the grinding cup 20 during boiling, resulting in a stable working environment and effectively improving the accuracy and sensitivity of pressure detection.

[0040] This utility model does not limit the specific structure of the mounting bracket 60, which can be any one of the following embodiments 1-3: Implementation Example 1, such as Figure 1-3 As shown, the mounting bracket 60 is a mounting cover surrounding the circumference of the grinding cup 20, and the pressure sensor 40 is fixed to the outer wall of the mounting cover. More specifically, the mounting bracket 60 includes a first bracket 61 and a second bracket 62, which are arranged sequentially along the circumference of the grinding cup 20 and spliced ​​together as a single unit. Optionally, the pressure sensor 40 is fixed to the first bracket 61. Optionally, the first bracket 61 and the second bracket 62 are connected by a snap-fit.

[0041] In this embodiment, the mounting bracket 60 is set as a mounting cover surrounding the outer periphery of the grinding cup 20, and the pressure sensor 40 is fixed to the outer wall of the mounting cover. The mounting cover provides a stable installation for the pressure sensor 40 to block the vibration transmission of the pipeline 30, while also isolating the heat of the grinding cup 20 in all directions. It can also integrate the functions of heat preservation and sound insulation of the grinding cup 20, realizing functional integration. There is no need to set up a special pressure sensor 40 fixing structure, simplifying the structure of the food processing machine, and making efficient use of the limited installation space of the main housing 10, resulting in a compact structure.

[0042] By combining the first bracket 61 and the second bracket 62 separately to form an integrated mounting bracket 60, during assembly, the first bracket 61 and the second bracket 62 can be positioned at corresponding positions on the outer periphery of the grinding cup 20, and then assembled to form the complete mounting bracket 60. This eliminates the need for a complete installation of the grinding cup 20, simplifying the installation process and improving assembly convenience and efficiency. The mounting bracket 60, after the first bracket 61 and the second bracket 62 are integrated along the circumference of the grinding cup 20, provides comprehensive insulation against heat from the grinding cup 20, preventing heat interference with the pressure sensor 40 and improving the detection accuracy of the pressure sensor 40. The first bracket 61 and the second bracket 62 are independently set, and the pressure sensor 40 can be optionally installed on either the first bracket 61 or the second bracket 62, resulting in a simple installation structure and convenient disassembly and maintenance.

[0043] In one specific embodiment of this example, the mounting cover and the outer wall of the grinding cup 20 are sealed together to form a cooling channel, through which a cooling medium is introduced to cool the grinding cup 20. Specifically, the side wall of the mounting cover has an air inlet and an air outlet, and a fan is installed at the air inlet or the air outlet. When the fan operates, cold air is introduced into the cooling channel from the air inlet and discharged from the air outlet, thereby achieving circulating air cooling of the grinding cup 20.

[0044] Of course, it is understood that in another specific embodiment of this example, the cooling channel can be a water flow channel. The cover connects the inlet pipe and the outlet pipe. Water is supplied to the inlet pipe of the cooling channel by the water supply device of the food processor or the kitchen water circuit. The water flows into the cooling channel and flows along the outer wall of the grinding cup 20, and is discharged from the outlet pipe, thereby realizing the circulating water cooling of the grinding cup 20.

[0045] Of course, in other specific embodiments under this example, the mounting cover is a heat insulation cover that fits against the outer wall of the crushing cup 20, and the heat insulation cover is provided with heat insulation cotton; or, the mounting cover is a sound insulation cover that is spaced around the outer periphery of the crushing cup 20, and the sound insulation cover is provided with sound insulation cotton.

[0046] This embodiment utilizes a sealing fit between the mounting cover and the outer wall of the grinding cup 20 to form a cooling channel. This not only cools the grinding cup 20 but also increases the distance between the mounting cover and the grinding cup 20. Combined with the isolation provided by the mounting cover structure itself, the pressure sensor 40 is further removed from the grinding cup 20, avoiding interference from the heat of the grinding cup 20 and improving detection accuracy. The sealed cooling channel ensures the orderly flow of the cooling medium within the channel. For example, introducing water or air into the cooling channel prevents leakage or loss of the cooling medium, thus efficiently removing the heat generated by the grinding cup 20 during processing and quickly reducing its temperature. On one hand, after the soy milk is cooked, the cooling medium cools the grinding cup 20, achieving rapid cooling of the soy milk for direct consumption and reducing waiting time. On the other hand, when the pressure sensor 40 detects that the pressure in the grinding cup 20 exceeds a preset value, the cooling medium cools the grinding cup 20, achieving rapid pressure reduction and improving safety.

[0047] In this embodiment, the conduit 30 can be used for pressure relief or to supply media to the pulverizing cup 20.

[0048] As a preferred option, such as Figure 1 As shown, the food processor also includes a liquid receiving container 70 and a supply device 80. The pipeline 30 includes a first pipeline 31 communicating with the liquid receiving container 70, a second pipeline 32 communicating with the supply device 80, and a tee connector 90. The tee connector 90 has a first connector communicating with the first pipeline 31, a second connector communicating with the second pipeline 32, and a third connector communicating with the inner cavity of the grinding cup 20. The mounting port 301 and the control valve 50 are both located in the first pipeline 31. Therefore, the first pipeline 31 connects the grinding cup 20 and the liquid receiving container 70 for venting and depressurizing. More specifically, the grinding cup 20 is equipped with a drain valve. The food processor also includes a liquid receiving container 70 located below the drain valve. The control valve 50 is a pressure relief valve with an outlet facing the liquid receiving container 70, allowing the grinding cup 20 to communicate with the liquid receiving container 70 through the pipeline 30.

[0049] The receiving container 70 includes a receiving cup 71 and a residual water box 72. The receiving cup 71 is used to receive the liquid discharged from the drain valve. The first pipeline 31 is connected to the residual water box 72, and the outlet of the pressure relief valve faces the residual water box 72. The supply device 80 includes a water tank for water supply or an air pump or steam generator for air supply, etc.

[0050] By setting the control valve 50 as a pressure relief valve and the pipeline 30 as a pressure relief pipeline 30, the pressure relief requirements of the grinding cup 20 are met. The grinding cup 20 quickly releases pressure when under high pressure, avoiding safety hazards caused by excessive pressure and ensuring safe operation. The pressure sensor 40 is installed at the mounting port 301 of the pipeline 30, directly detecting the air pressure discharged from the grinding cup 20. The detection is accurate, direct, and more sensitive and reliable. The food processor can control the motor's operation and the opening and closing of the pressure relief valve based on the accurate air pressure detected by the pressure sensor 40. The pressure relief valve has an outlet facing the liquid receiving container 70, allowing the grinding cup 20 to connect to the liquid receiving container 70 via the pipeline 30. This allows the high-temperature steam from the grinding cup 20 or the condensate from the steam in the pipeline 30 to be discharged into the liquid receiving container 70, preventing steam burns to the user and preventing condensate from dripping onto the work surface, making it safer and more convenient to use.

[0051] This embodiment achieves the switching and integration of pathways between the liquid receiving container 70, the supply device 80, and the pulverizing cup 20 by setting a three-way connector 90. This eliminates the need for separate independent pipelines 30 for each different structure, simplifying the internal pipeline layout and saving installation space within the main housing 10. Depending on actual needs, the mounting port 301 for the pressure sensor 40 and the control valve 50 can both be located in the first pipeline 31 or the second pipeline 32, allowing for flexible installation of the pressure sensor 40. Regardless of which pipeline 30 the pressure sensor 40 is installed in, the mounting bracket 60 provides mechanical shock absorption and heat insulation, improving the detection accuracy of the pressure sensor 40.

[0052] It is understood that the specific structure of the pipeline 30 in this embodiment can still be applied to other embodiments of this utility model.

[0053] like Figure 2 , 3 As shown, preferably, in this embodiment, the pressure sensor 40 is provided with a threaded section 41, and the mounting port 301 is threadedly connected to the threaded section 41.

[0054] The pressure sensor 40 and the mounting port 301 are connected by threads, which not only ensures the reliable fixation of the pressure sensor 40 and the pipeline 30, enabling the pressure sensor 40 to reliably detect the flow pressure in the pipeline 30 and realize the detection of the air pressure in the crushing cup 20, but also allows for flexible installation and removal of the pressure sensor 40, facilitating the maintenance and replacement of the pressure sensor 40.

[0055] like Figure 2 , 3 As shown, in this preferred embodiment, the mounting bracket 60 is provided with a limiting groove 601 with the opening away from the crushing cup 20, and the pressure sensor 40 is fixed in the limiting groove 601.

[0056] Preferably, in this embodiment, the mounting bracket 60 is provided with a snap fastener, and the pressure sensor 40 is snapped onto the mounting bracket 60 via the snap fastener. For example, when the mounting bracket 60 is provided with a limiting groove 601, the snap fastener is provided on the side wall of the limiting groove 601.

[0057] A limiting groove 601 is provided on the mounting bracket 60 away from the crushing cup 20. The limiting groove 601 can provide a stable installation position for the pressure sensor 40, preventing the sensor from shifting or loosening during equipment operation. The limiting groove 601 also effectively isolates the heat of the crushing cup 20, ensuring the accuracy of the pressure sensor 40 detection and improving the convenience and firmness of the pressure sensor 40 installation.

[0058] The mounting bracket 60 features a snap-fit ​​mechanism that allows the pressure sensor 40 to be directly snapped onto it without the need for additional fastening tools or connectors. This enables rapid installation and removal of the pressure sensor 40, significantly simplifying the equipment assembly process and facilitating sensor replacement or repair during subsequent maintenance, thereby improving assembly and maintenance efficiency. The snap-fit ​​mechanism securely fixes the pressure sensor 40 to the mounting bracket 60, and together with the bracket's isolation function between the pressure sensor 40 and the crushing cup 20, effectively prevents the pressure sensor 40 from loosening or shifting due to mechanical vibration of the pipeline 30. This ensures the stability of the pressure sensor 40's detection position, guarantees stable detection performance, and improves detection accuracy.

[0059] Of course, in practice, the pressure sensor 40 can also be fixed to the mounting bracket 60 with screws, or the pressure sensor 40 can be interference-fitted into the limiting groove 601 of the mounting bracket 60.

[0060] In Implementation Example 2, unlike Implementation Example 1, the mounting bracket 60 in this implementation example is a support for holding the crushing cup 20.

[0061] Specifically, the support base is provided with a mounting portion for mounting the pressure sensor 40, which isolates the pressure sensor 40 from the grinding cup 20. It can be understood that the side wall of the support base is misaligned with the grinding cup 20, thus forming the mounting portion on the side wall of the support base, and the pressure sensor 40 is fixed to the outside of the side wall of the support base; alternatively, the mounting portion is an extension wall extending upward from the top wall of the support base to the side of the grinding cup 20, and the pressure sensor 40 is fixed to the side wall of the extension wall on the side away from the grinding cup 20.

[0062] More specifically, the support base separates a motor mounting cavity with a top opening and an assembly cavity with a side opening. The motor mounting cavity houses the motor, and the main housing 10 is provided with an assembly port that communicates with the side opening of the assembly cavity. The assembly cavity houses a liquid receiving container 70.

[0063] In this embodiment, the mounting bracket 60 serves as a support base, which not only bears the load of the crushing cup 20 but also secures and isolates the pressure sensor 40 through the mounting section. This eliminates the need for an additional mounting bracket 60, simplifying the internal structure of the equipment. The mounting section isolates the pressure sensor 40 from the crushing cup 20, effectively blocking heat transfer from the crushing cup 20 and interference from vibrations in the pipeline 30, ensuring accurate pressure detection. The top-opening motor mounting cavity separated by the support base facilitates the housing and installation of the motor, while the side-opening assembly cavity, combined with the assembly port of the main housing 10, allows for convenient removal and placement of the liquid receiving container 70 from the side. This achieves a reasonable layout of the crushing cup 20, motor, and liquid receiving container 70, fully utilizing the internal space of the main housing 10. The compact structure reduces the overall size of the machine and minimizes its footprint.

[0064] Another difference from Embodiment 1 is that the pipe 30 in this embodiment is a supply pipe 30. Specifically, in this embodiment, the food processor also includes a supply device 80 installed on the main housing 10. The supply device is, for example, a water tank. The grinding cup 20 is connected to the supply device 80 via the pipe 30, and the control valve 50 is a water pump or a check valve connecting the water tank and the grinding cup. Of course, the supply device 80 can also be a steam generator, and the control valve 50 can be an air pump or a check valve.

[0065] The grinding cup 20 is connected to the supply device 80 via pipe 30. The supply device 80 supplies water or air to the grinding cup 20, achieving a self-cleaning effect for the food processor. Furthermore, the air supply can also be used to dry the grinding cup 20, keeping it dry and hygienic. The control valve 50 is a water pump, air pump, or check valve. Correspondingly, the pressure sensor 40 is installed at the installation port 301 of pipe 30. After the control valve 50 is closed, the air pressure inside the grinding cup 20 can be detected, and the motor can be controlled based on the air pressure in the grinding cup 20.

[0066] Implementation Example 3 differs from Implementation Example 1 in that the mounting bracket 60 in this implementation example is a coupling bracket.

[0067] Specifically, the crushing cup 20 includes a cup body 21 and a cup lid 22. The cup lid 22 has a communication port. The pipeline 30 includes a first tube located in the cup lid 22 and a second tube located inside the main housing 10. A coupling bracket for installing a coupling connector is provided inside the main housing 10. The second tube is connected to the first tube through the coupling connector. The mounting bracket 60 is a coupling bracket.

[0068] By setting a connecting port on the cup lid 22, the connecting port is positioned higher, reducing the risk of slurry overflowing from the connecting port due to heat during pulping, and also reducing the probability of slurry residue clogging the connecting port. This ensures smooth pressure relief and reliable supply of media to the crushing cup 20. The mounting bracket 60 is a coupling bracket, thus achieving functional integration. It integrates the coupling connection between the first and second pipes, while also fixing and isolating the pressure sensor 40. This eliminates the need for an additional mounting bracket 60, simplifying the internal structure of the equipment.
