Description

Technical Field

[0001] This utility model relates to the technical field of food crushing devices, specifically to food crushing devices. Background Technology

[0002] Currently, food processing devices such as blenders on the market mainly achieve cleaning through high-speed mechanical stirring combined with water rinsing. However, food residue can still easily remain in hard-to-reach areas such as blade gaps and lid seals. These food residues can easily breed bacteria over time.

[0003] Traditional cleaning methods for blenders typically rely on high-power motors to drive the blades, resulting in high energy consumption, loud noise, and an inability to thoroughly remove sticky stains such as fruit juice fibers and grain starch. Utility Model Content

[0004] In view of this, the present invention provides a food crushing device to solve the problem that the traditional cleaning mode of a blender usually relies on a high-power motor to drive the blades to rotate, resulting in high energy consumption, loud noise, and inability to thoroughly remove sticky stains such as fruit juice fibers and grain starch.

[0005] In a first aspect, this utility model provides a cleaning method, comprising:

[0006] Obtain the operating mode of the food crushing device;

[0007] In cleaning mode, the ultrasonic module and the stirring module are controlled to operate synchronously.

[0008] The stirring speed of the stirring module in the cleaning mode is lower than that in the crushing mode.

[0009] Beneficial effects: In cleaning mode, the ultrasonic module and the stirring module operate synchronously. The ultrasonic module generates high-frequency vibration waves, causing the liquid to produce a micro-jet effect, impacting the blades and cavity surfaces, loosening and removing stubborn stains. The stirring module drives the blades to rotate at a lower stirring speed, further agitating the liquid. Combined with the vibration of the ultrasonic module, this ensures thorough cleaning without blind spots. Furthermore, through the synergistic effect of the ultrasonic module and the stirring module, stubborn stains in traditional cleaning blind spots such as the blade gaps of the food crusher and the sealing ring of the cup lid are effectively removed. It has a particularly significant cleaning effect on sticky stains such as fruit juice fibers and grain starch. Moreover, in cleaning mode, the stirring speed of the stirring module is lower than that in crushing mode, which also significantly reduces energy consumption and operating noise, making it more energy-efficient and environmentally friendly compared to traditional high-power motor drive methods.

[0010] In one optional implementation, if it is a cleaning mode, controlling the ultrasonic module and the stirring module to operate synchronously includes:

[0011] Obtain stain information about the stain to be cleaned;

[0012] The first operating frequency of the ultrasonic module and the first stirring speed of the stirring module are obtained based on the stain information.

[0013] The ultrasonic module is controlled to operate at the first operating frequency, and the stirring module is controlled to operate at the first stirring speed.

[0014] Beneficial effects: Different stains present different cleaning challenges. Therefore, matching different first operating frequencies and first stirring speeds according to different stain information can improve the applicability of the first operating frequency and first stirring speed, ensuring that each type of stain has a better cleaning effect.

[0015] In one optional implementation, obtaining stain information of the stain to be cleaned includes:

[0016] Acquire pressure changes during the flow of cleaning liquid;

Therefore, when obtaining stain information through pressure changes, the stirring module can be controlled to run at the second stirring speed for a preset time to make the cleaning liquid flow, thereby obtaining the pressure change of the cleaning liquid. The viscosity or adhesion of the stain can then be determined by the pressure change of the cleaning liquid.

[0026] Beneficial effects: By analyzing the light reflection or light transmission characteristics of the cleaning liquid, the concentration or type of stain in the cleaning liquid can be determined, thereby identifying whether the stain is an oily stain, a fibrous stain, or a starchy stain.

[0027] In one optional implementation, obtaining stain information of the stain to be cleaned further includes:

[0028] Obtain stain information input by the user.

[0029] Beneficial effects: When the user automatically inputs stain information through the control panel, the control module can directly obtain the stain information and obtain the first operating frequency of the ultrasonic module and the first stirring speed of the stirring module based on the stain information.

[0030] In one optional implementation, if the cleaning mode is selected, the ultrasonic module and the stirring module are controlled to operate synchronously, further comprising:

[0038] If further cleaning is required, the food crushing device is controlled to enter the re-cleaning stage;

[0039] If further cleaning is not required, the food crushing device is controlled to enter the post-processing stage.

[0040] Beneficial effects: If both the ultrasonic module and the stirring module stop operating, the initial cleaning mode is considered to be over. At this time, the cleaning effect is obtained, and it can be determined whether cleaning is needed again based on the cleaning effect, thus ensuring the cleaning effect.

[0041] In one optional implementation, controlling the food crushing device to enter a re-cleaning phase includes:

[0057] Beneficial effects: By configuring the ultrasonic module, it can be controlled to operate synchronously with the stirring module in cleaning mode. The ultrasonic module generates high-frequency vibration waves, causing the liquid to produce a micro-jet effect, impacting the blades and cavity surfaces, loosening and removing stubborn stains. The stirring module drives the blades to rotate at a lower stirring speed, further agitating the liquid. Combined with the vibration of the ultrasonic module, this ensures thorough cleaning without blind spots. Through the synergistic effect of the ultrasonic and stirring modules, stubborn stains in traditionally hard-to-clean areas such as blade gaps and lid seals in food shredders are effectively removed, especially showing significant cleaning effects on sticky stains such as fruit juice fibers and grain starch. Furthermore, in cleaning mode, the stirring speed of the stirring module is lower than that in shredding mode, significantly reducing energy consumption and operating noise, making it more energy-efficient and environmentally friendly compared to traditional high-power motor drives.

[0089] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0090] The following is combined Figures 1 to 11 The following describes embodiments of the present invention.

[0091] According to an embodiment of the present invention, a cleaning method is provided, comprising:

[0092] S1. Obtain the operating mode of the food crushing device.

[0093] The specific method for obtaining the operating mode of the food crusher may include obtaining the operating mode selected by the user through the control panel, which generally includes a crushing mode and a cleaning mode. The crushing mode is usually used for crushing operations such as making soy milk or juicing. Before the food crusher enters the cleaning mode, an appropriate amount of water needs to be added to the crushing chamber 11 of the food crusher. An appropriate amount of detergent may also be added to the water as needed for cleaning, or no detergent may be added. Furthermore, the addition of water and detergent can be done manually by the user or automatically by the food crusher; no restrictions are placed on the method of addition.

[0094] S2. In cleaning mode, control the ultrasonic module 3 and the stirring module 4 to operate synchronously.

[0095] The stirring speed of the stirring module 4 in the cleaning mode is lower than that in the crushing mode.

[0096] In cleaning mode, the ultrasonic module 3 and the stirring module 4 operate synchronously. The ultrasonic module 3 generates high-frequency vibration waves, causing the liquid to produce a micro-jet effect, impacting the blade 43 and the surface of the cavity, loosening and removing stubborn stains. The stirring module 4 drives the blade 43 to rotate at a low stirring speed, further agitating the liquid. Combined with the vibration of the ultrasonic module 3, this ensures thorough cleaning without any blind spots. Through the synergistic effect of the ultrasonic module 3 and the stirring module 4, stubborn stains in traditional cleaning blind spots such as the gaps between the blades 43 of the food crusher and the sealing ring of the cup lid are effectively removed. It has a particularly significant cleaning effect on sticky stains such as fruit juice fibers and grain starch. In addition, the stirring speed of the stirring module 4 in cleaning mode is lower than that in crushing mode, which also significantly reduces energy consumption and operating noise, making it more energy-efficient and environmentally friendly compared to traditional high-power motor drive methods.

[0097] In a specific implementation, in the cleaning mode, the stirring speed of the stirring module 4 is controlled within the range of less than or equal to 200 rpm.

[0098] In a specific implementation, when the food crushing device has multiple crushing modes, the stirring speed of the stirring module 4 in the cleaning mode is less than the stirring speed of the stirring module 4 in all crushing modes. When the food crushing device has only one crushing mode, the stirring speed of the stirring module 4 in the cleaning mode is less than its stirring speed in the crushing mode.

[0099] In related technologies, some blenders improve cleaning performance by adding a spray structure or a detachable blade 43 design. However, insufficient spray water pressure makes it difficult to penetrate the gaps between the blades 43, and frequent disassembly and reassembly of the blades 43 increases the complexity of user operation and the risk of wear. In this embodiment, through the synergistic effect of the ultrasonic module 3 and the stirring module 4, stubborn stains in traditional cleaning dead spots such as the gaps between the blades 43 of the food crushing device and the sealing ring of the cup lid are effectively removed. It has a significant cleaning effect, especially on sticky stains such as fruit juice fibers and grain starch, without the need for frequent disassembly and reassembly of the blades 43, and without the need to add a spray structure.

[0100] In related technologies, some blenders use high-temperature steam cleaning, but high temperatures may accelerate the aging of seals and pose a risk of burns. In this embodiment, the ultrasonic module 3 and the stirring module 4 work together to effectively remove stubborn stains from traditionally hard-to-clean areas such as the gaps in the blades 43 of the food crushing device and the sealing ring of the cup lid. It has a particularly significant cleaning effect on sticky stains such as fruit juice fibers and grain starches, eliminating the need for high-temperature steam cleaning, avoiding accelerated aging of seals, and avoiding the risk of burns.

[0101] In a further embodiment, if it is in crushing mode, the stirring module 4 is controlled to operate independently. Alternatively, in crushing mode, the stirring module 4 and the ultrasonic module 3 can also be controlled to operate synchronously, except that the stirring speed of the stirring module 4 in crushing mode is higher than that in cleaning mode.

[0102] In one embodiment, if it is a cleaning mode, controlling the ultrasonic module 3 and the stirring module 4 to operate synchronously includes:

[0103] S21. Obtain stain information for the stain to be cleaned.

[0104] S22. Obtain the first operating frequency of the ultrasonic module 3 and the first stirring speed of the stirring module 4 based on the stain information.

[0105] S23. Control the ultrasonic module 3 to operate at the first operating frequency, and control the stirring module 4 to operate at the first stirring speed.

[0106] Different stains present different cleaning challenges. Therefore, matching different initial operating frequencies and initial stirring speeds to different stain information can improve the applicability of the initial operating frequency and initial stirring speed, ensuring that each type of stain has a better cleaning effect.

[0107] In a specific implementation, the stains to be cleaned by the food crushing device include grease stains, fibrous stains, and starch stains.

[0108] In a further embodiment, if the stain information indicates that the stain to be cleaned is an grease-based stain, the first operating frequency of the ultrasonic module 3 can be selected between 30kHz and 40kHz, and the first stirring speed of the stirring module 4 can be less than or equal to 100rpm. The ultrasonic module 3, using a lower frequency, helps loosen the grease-based stain, making it easier to clean. A first operating frequency in the 30kHz-40kHz range effectively disrupts the bonds between grease molecules, thereby improving cleaning efficiency. Specifically, the first operating frequency can be 30kHz, 40kHz, or 35kHz; preferably, it is 40kHz. The first stirring speed of the stirring module 4, less than or equal to 100rpm, is suitable for grease-based stains and avoids excessive stirring that could cause liquid splashing.

[0109] In another further embodiment, if the stain information indicates that the stain to be cleaned is a fibrous stain, the first operating frequency of the ultrasonic module 3 can be selected between 70kHz and 80kHz, and the first stirring speed of the stirring module 4 can be selected between 100rpm and 150rpm. The ultrasonic module 3, using a higher frequency, helps to penetrate the fiber structure, loosening and removing fibrous stains. A first operating frequency in the 70kHz-80kHz range can effectively vibrate the fiber structure, making it easier to clean. Specifically, the first operating frequency can be 70kHz, 80kHz, or 75kHz; preferably, it is 80kHz. The first stirring speed of the stirring module 4, selected between 100rpm and 150rpm, is suitable for fibrous stains, enhancing liquid flowability and assisting ultrasonic vibration. Specifically, the first stirring speed can be 100rpm, 150rpm, or 125rpm.

[0110] In another further embodiment, if the stain information of the stain to be cleaned indicates a starch-based stain, the first operating frequency of the ultrasonic module 3 can be selected between 20kHz and 38kHz, and the first stirring speed of the stirring module 4 can be selected between 150rpm and 200rpm. The ultrasonic module 3, with its suitable frequency range, is well-suited for removing sticky stains. Specifically, the first operating frequency can be 20kHz, 38kHz, or 28kHz; preferably, the first operating frequency is 28kHz. The first stirring speed of the stirring module 4, selected between 150rpm and 200rpm, is suitable for starch-based stains, accelerating liquid circulation and improving cleaning efficiency. Specifically, the first stirring speed can be 150rpm, 200rpm, or 175rpm.

[0111] In one embodiment, obtaining stain information of the stain to be cleaned includes:

[0112] S211. Obtain the pressure change during the flow of the cleaning liquid.

[0113] S212. Determine the viscosity or adhesion of the stain based on the pressure change.

[0114] By measuring the pressure changes during the flow of the cleaning liquid, the viscosity or adhesion of the stain can be determined, thereby identifying the type of stain, such as whether it is an oily stain, a fibrous stain, or a starchy stain, and then matching the corresponding first operating frequency and first stirring speed.

[0115] In one embodiment, obtaining the pressure change during the flow of the cleaning liquid includes:

[0116] S2111, Control the stirring module 4 to run at the second stirring speed for a preset time.

[0117] S2112, The pressure detection structure controls the pressure changes during the flow of clean liquid.

[0118] When the cleaning liquid is not flowing, the pressure will remain constant. Therefore, to obtain stain information through pressure changes, the stirring module 4 can be controlled to run at the second stirring speed for a preset time to make the cleaning liquid flow, thereby obtaining the pressure change of the cleaning liquid. The viscosity or adhesion of the stain can then be determined by the pressure change of the cleaning liquid.

[0119] In one embodiment, obtaining stain information of the stain to be cleaned includes:

[0120] S213. Obtain the light reflection or light transmission characteristics of the cleaning liquid.

[0121] S214. Analyze the concentration or type of stains in the cleaning liquid based on the light reflection characteristics or the light transmission characteristics.

[0122] By analyzing the light reflection or light transmission characteristics of the cleaning liquid, the concentration or type of stain in the cleaning liquid can be determined, thereby identifying whether the stain is an oily stain, a fibrous stain, or a starchy stain, and then matching the corresponding first operating frequency and first stirring speed.

[0123] In one embodiment, obtaining stain information of the stain to be cleaned further includes:

[0124] S215. Obtain stain information input by the user.

[0125] When the user automatically inputs stain information through the control panel, the control module can directly obtain the stain information and obtain the first operating frequency of the ultrasonic module 3 and the first stirring speed of the stirring module 4 based on the stain information.

[0126] In one embodiment, if the cleaning mode is selected, controlling the ultrasonic module 3 and the stirring module 4 to operate synchronously further includes:

[0127] S24. Obtain the temperature information of the cleaning liquid.

[0128] S25. Control the operation of the ultrasonic module 3 and the stirring module 4 according to the temperature information.

[0129] The operation of the ultrasonic module 3 and the stirring module 4 is controlled based on temperature information to avoid the impact of high temperature on the equipment or cleaning effect.

[0130] In one embodiment, the cleaning method further includes:

[0131] S3. Obtain the operating status of the ultrasonic module 3 and the stirring module 4.

[0132] S4. If both the ultrasonic module 3 and the stirring module 4 stop operating, a cleaning effect is achieved.

[0133] S5. Determine whether further cleaning is needed based on the cleaning effect.

[0134] S6. If further cleaning is required, control the food crushing device to enter the re-cleaning stage.

[0135] S7. If no further cleaning is required, control the food crushing device to enter the post-processing stage.

[0136] If both the ultrasonic module 3 and the stirring module 4 stop operating, the initial cleaning mode is considered to be over. At this time, the cleaning effect is obtained, and it can be determined whether cleaning is needed again based on the cleaning effect, so as to ensure the cleaning effect.

[0137] In a specific implementation, the method for obtaining the cleaning effect is consistent with the method for obtaining stain information of the stain to be cleaned, including: obtaining the pressure change during the flow of the cleaning liquid; determining the viscosity or adhesion of the stain based on the pressure change; and / or obtaining the light reflection or light transmission characteristics of the cleaning liquid; analyzing the stain concentration or stain type in the cleaning liquid based on the light reflection or light transmission characteristics.

[0138] In one embodiment, controlling the food crushing device to enter a re-cleaning phase includes:

[0139] S61. Obtain the second operating frequency of the ultrasonic module 3 and the third stirring speed of the stirring module 4 based on the cleaning effect.

[0140] S62. Control the ultrasonic module 3 to operate at the second operating frequency, and control the stirring module 4 to operate at the third stirring speed.

[0141] By modifying the second operating frequency and the third stirring speed based on the cleaning effect, the applicability of the second operating frequency and the third stirring speed can be improved, ensuring a better cleaning effect.

[0143] S71. Control the food crushing device to drain and rinse;

[0144] S72. Control the high-temperature sterilization of the heating structure.

[0145] In the post-processing stage, the food crushing device can be automatically drained and rinsed first, and then the heating structure can be sterilized at high temperature to keep the inside of the equipment dry and prevent bacterial growth. In a preferred embodiment, the heating structure uses low-power heating in the post-processing stage.

[0146] In one embodiment, controlling the food crushing device to enter the post-processing stage includes:

[0147] S73. Control the food crushing device to issue a reminder to drain and rinse.

[0148] S74. After drainage and rinsing, control the high-temperature disinfection of the heating structure.

[0149] During the post-processing stage, the food crushing device can be controlled to issue a reminder to drain and rinse, so as to remind the user to drain and rinse. After the user drains and rinses, the heating structure is controlled to perform high-temperature sterilization to keep the inside of the equipment dry and prevent bacterial growth.

[0150] According to an embodiment of the present invention, another aspect provides a food crushing device, including a device body 1, a cover 2, an ultrasonic module 3, a stirring module 4, and a control module; the device body 1 has a crushing chamber 11 inside; the cover 2 is detachably and sealingly covered on the device body 1; the ultrasonic module 3 is disposed on the device body 1, with at least a portion of the ultrasonic module 3 located within the crushing chamber 11; the stirring module 4 is disposed on the device body 1, with at least a portion of the stirring module 4 rotatably disposed within the crushing chamber 11 and spaced apart from the ultrasonic module 3; the control module is disposed on the device body 1 and is communicatively connected to both the ultrasonic module 3 and the stirring module 4, and the control module is used to control the ultrasonic module 3 and the stirring module 4 to operate synchronously in a cleaning mode, and to perform the aforementioned cleaning method.

[0151] By configuring the ultrasonic module 3, it can be controlled to operate synchronously with the stirring module 4 in cleaning mode. The ultrasonic module 3 generates high-frequency vibration waves, causing the liquid to produce a micro-jet effect, impacting the blade 43 and the cavity surface, loosening and removing stubborn stains. The stirring module 4 drives the blade 43 to rotate at a lower stirring speed, further agitating the liquid. Combined with the vibration of the ultrasonic module 3, this ensures thorough cleaning without blind spots. Through the synergistic effect of the ultrasonic module 3 and the stirring module 4, stubborn stains in traditionally hard-to-clean areas such as the gaps between the blades 43 of the food crusher and the sealing ring of the cup lid are effectively removed, especially showing significant cleaning effects on sticky stains such as fruit juice fibers and grain starch. Furthermore, in cleaning mode, the stirring speed of the stirring module 4 is lower than that in crushing mode, significantly reducing energy consumption and operating noise, making it more energy-efficient and environmentally friendly compared to traditional high-power motor drives. The ultrasonic module 3 and the stirring module 4 are spaced apart to avoid interference.

[0152] In one embodiment, a detection structure is further included, disposed within the crushing chamber 11. The detection structure is communicatively connected to the control module and is used to detect stain information of the stain to be cleaned.

[0153] The detection structure is used to detect stain information of the stain to be cleaned. The control module obtains the first operating frequency of the ultrasonic module 3 and the first stirring speed of the stirring module 4 based on the stain information, and controls the ultrasonic module 3 to operate at the first operating frequency and the stirring module 4 to operate at the first stirring speed. Different stains present different cleaning challenges; therefore, matching different first operating frequencies and first stirring speeds according to different stain information can improve the applicability of the first operating frequency and first stirring speed, ensuring a good cleaning effect for each type of stain.

[0154] In one embodiment, the detection structure includes a pressure sensor disposed within the crushing chamber 11 and communicatively connected to the control module for detecting pressure changes in the cleaning liquid.

[0155] The pressure sensor is used to detect pressure changes in the cleaning liquid. The control module determines the viscosity or adhesion of the stain based on the pressure changes, and then determines the type of stain, that is, whether the stain is an oily stain, a fibrous stain, or a starchy stain, and then matches the corresponding first operating frequency and first stirring speed.

[0156] In one embodiment, the detection structure includes an optical sensor disposed within the crushing chamber 11 and communicatively connected to the control module, for detecting the light reflection or light transmission characteristics of the cleaning liquid.

[0157] An optical sensor is used to detect the light reflection or light transmission characteristics of the cleaning liquid. The control module analyzes the stain concentration or stain type in the cleaning liquid based on the light reflection or light transmission characteristics, and then determines the stain information, that is, determines whether the stain information belongs to grease stain, fiber stain or starch stain, and then matches the corresponding first operating frequency and first stirring speed.

[0158] In one embodiment, the detection structure includes a temperature sensing component disposed within the crushing chamber 11 and communicatively connected to the control module for detecting the temperature of the cleaning liquid.

[0159] The temperature sensing component is used to detect the temperature of the cleaning liquid. The control module controls the operation of the ultrasonic module 3 and the stirring module 4 based on the temperature information to avoid the impact of high temperature on the equipment or the cleaning effect.

[0160] In one embodiment, the detection structure is positioned close to the ultrasonic module 3.

[0161] The detection structure is located near the ultrasonic module 3, which facilitates installation and disassembly, as well as connection with the control module.

[0162] In one embodiment, the ultrasonic module 3 includes an ultrasonic transducer embedded in the cavity wall of the crushing chamber 11, and the ultrasonic transducer is communicatively connected to the control module.

[0163] The ultrasonic transducer generates high-frequency vibration waves through piezoelectric ceramic elements and is embedded in the cavity wall of the crushing chamber 11, which can effectively fix the ultrasonic transducer.

[0164] In one embodiment, the ultrasonic module 3 further includes a protective layer that covers the exterior of the ultrasonic transducer.

[0165] The protective layer protects the ultrasonic transducer, ensuring the long-term stable operation of the food crushing device and avoiding potential safety hazards from high-temperature cleaning.

[0166] In this specific implementation, the protective layer is a food-grade silicone protective layer, ensuring it is non-toxic, heat-resistant, and aging-resistant, meeting food safety standards. The thickness of the protective layer should be moderate, ensuring both airtightness and preventing it from being too thick to affect the transmission efficiency of ultrasonic waves. A thickness of approximately 0.3 mm is recommended.

[0167] In a further embodiment, the wall of the crushing chamber 11 is provided with a groove, the shape of which matches the shape of the ultrasonic transducer, and the ultrasonic transducer fits tightly with the groove wall. The depth of the groove should be sufficient to accommodate the ultrasonic transducer and its protective layer, ensuring the stable installation of the ultrasonic transducer. Positioning pins or positioning slots can be provided in the groove to ensure accurate installation of the ultrasonic transducer and avoid poor sealing due to installation deviation. A high-strength adhesive is used to fix the protective layer in the groove, ensuring that the protective layer is tightly adhered to both the transducer and the groove wall, preventing liquid seepage. In a preferred embodiment, epoxy resin is used to seal the joint between the ultrasonic transducer and the groove, forming double protection to prevent liquid penetration. Screws or clips can also be used to fix the ultrasonic transducer in the groove, ensuring that it does not loosen during vibration. During the production process, the food crushing device undergoes an airtightness test to ensure that the sealing performance of each device meets the standards.

[0168] In one embodiment, the device body 1 includes a base 12 and a cup body 13; the control module is disposed on the base 12; the cup body 13 is provided with the crushing chamber 11, and the cup body 13 is detachably connected to the base 12; the stirring module 4 includes a stirring motor 41, a stirring shaft 42, and a blade 43, the stirring motor 41 being disposed on the base 12; the stirring shaft 42 is rotatably and sealingly connected to the bottom of the cup body 13, one end being disposed in the crushing chamber 11 and fixedly connected to the blade 43, and the other end being detachably connected to the power output shaft of the stirring motor 41; the portion of the ultrasonic module 3 located in the crushing chamber 11 is spaced apart from the stirring shaft 42 in the radial direction and spaced apart from the blade 43 in the axial direction of the stirring shaft 42.

[0169] The portion of the ultrasonic module 3 located within the crushing chamber 11 is spaced apart from the stirring shaft 42 in the radial direction and spaced apart from the blade 43 in the axial direction of the stirring shaft 42. This arrangement prevents interference between the ultrasonic module 3 and the blade 43, providing good protection for both the blade 43 and the ultrasonic module 3.

[0170] In one embodiment, the food crushing device further includes a heating structure disposed within the crushing chamber 11, the heating structure being communicatively connected to the control module.

[0171] The heating structure can sterilize the inside of the equipment at high temperatures, keep the inside of the equipment dry, and prevent bacterial growth.

[0172] In a specific implementation, the heating structure can be a heating plate. The heating plate uses low-power heating to sterilize the equipment through high-temperature evaporation, keeping the inside of the equipment dry and preventing bacterial growth. The heating plate can be attached to the cavity wall of the crushing chamber 11 and spaced apart from the ultrasonic module 3.

[0173] In one embodiment, the food crushing device is a high-speed blender.

[0174] According to an embodiment of the present invention, in another aspect, a computer-readable storage medium is also provided, the computer-readable storage medium storing computer instructions that, when executed, implement the above-described cleaning method.

[0175] The computer-readable storage medium provided by this utility model, through the cleaning method described above, has all the technical effects of the cleaning method described above.

[0176] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
