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] A food processing machine, such as the indirect transmission food processing machine disclosed in the applicant's earlier patent application (publication number CN102217905B), includes a pulverizing blade, a driven coupling connecting the pulverizing blade, a positioning shaft, a fixing device, and a motor-driven active coupling (i.e., a permanent magnet). The active coupling cooperates with the driven coupling to realize the transmission of the pulverizing blade. The aforementioned stirring blade assembly, composed of the pulverizing blade, driven coupling, positioning shaft, and fixing device, can be detachably installed as a whole inside a container (stirring cup), facilitating cleaning, eliminating the need for a blade shaft hole, simplifying the stirring cup structure, and avoiding leakage problems due to seal failure.

[0003] However, after using the food processor, users typically clean the mixing blade assembly separately and then let it air dry. When using it again, they manually reinstall the mixing blade assembly, which can sometimes result in it not being installed correctly. This is especially true when there is a large gap between the bottom of the mixing blade assembly and the bottom of the cup, or when there are particles on the bottom wall of the mixing cup. If the mixing blade is not installed evenly, it may be partially tilted or raised above the cup, causing the machine to misidentify it as properly installed. This means that if the user starts the machine without properly installing the mixing blade, the transmission of the mixing blade assembly may become unreliable or malfunction, the blade may not rotate properly, causing friction noise, and even posing safety risks such as blade jamming, blade flying, and splattering of the mixture, causing inconvenience to the user. Utility Model Content

[0004] This utility model provides a food processing machine based on a food processing machine with a stirring blade assembly that can be detached from the stirring cup. It solves the problem in the prior art where the stirring blade assembly is not installed flat, resulting in the stirring blade assembly being tilted or raised as a whole, which leads to the stirring blade assembly not being accurately detected and directly working, causing friction noise and safety risks.

[0005] The technical solution adopted in this utility model is as follows:

[0006] This utility model provides a food processing machine, including a main unit, a mixing cup installed on the main unit, and a mixing blade assembly detachably installed in the mixing cup. The mixing blade assembly includes a blade holder, a transmission disk rotatably installed in the blade holder, and a blade located above the blade holder. The transmission disk is fixed with a transmission shaft that extends from the blade holder and connects to the blade. The main unit is provided with a power drive device to drive the transmission disk. The power drive device drives the transmission disk to rotate remotely. The blade holder has detection elements arranged circumferentially. The food processing machine includes multiple detection devices located outside the mixing cup and spaced apart on the outer periphery of the blade holder. Each detection device cooperates with the detection elements to detect the position of the detection elements.

[0007] This invention provides a food processing machine that uses a power drive device to remotely drive a transmission disk, thereby achieving remote driving of a mixing blade assembly. The mixing blade assembly is detachably installed inside the mixing cup, facilitating cleaning and simplifying the mixing cup structure. Furthermore, the food processing machine includes multiple detection devices located outside the mixing cup and spaced apart from the outer periphery of the blade holder, arranged circumferentially on the blade holder. Each detection device cooperates with a detection element to detect the position of that element. Therefore, when each detection device detects a signal from the detection element, since the detection devices surround the outer periphery of the blade holder, meaning multiple detection elements in various positions of the blade holder are detected, it is confirmed that the blade holder as a whole has not been raised and is placed flat in the mixing cup without tilting due to obstructions such as particles. Therefore, by utilizing multiple detection devices in conjunction, not only is intelligent detection of whether the blade holder is installed achieved, but also the detection error of misjudging the blade holder as properly installed due to tilting is avoided. This also enables detection of whether the blade holder is installed flat and properly, intelligently identifying the installation status of the blade holder for accurate detection. This avoids machine noise and safety risks caused by users directly starting the machine and operating the mixing blade assembly even if the blade holder is not installed flat and properly. Thus, the food processing machine becomes intelligent, improving transmission reliability, reducing operating noise, enhancing safety, and improving the user experience.

[0008] In a preferred embodiment, the detection element is a detection magnet, and the detection device includes a linear Hall element.

[0009] By setting the detection element as a detection magnet and using a linear Hall element in the detection device, the magnetic field strength varies when the distance between the detection magnet and the linear Hall element is different. The linear Hall element will emit signals of different strengths. In other words, the detection signals of the knife holder in the three states of being installed in place, not installed, and installed on the mixing cup but not flat are significantly different. In particular, the signal difference between the knife holder not installed and the uneven installation state is amplified, making the detection of whether the knife holder is flat and installed in place more sensitive and accurate.

[0010] In a preferred embodiment, the detection element is ring-shaped.

[0011] By setting the detection element to a ring shape, the tool holder can be installed at multiple angles. Regardless of the installation angle, multiple detection devices can be used to check whether the installation is flat after installation. Moreover, the ring-shaped detection element can avoid the situation where the detection device cannot effectively detect due to the tool holder's installation orientation being off, reducing the detection blind zone and improving the accuracy of the detection.

[0012] In a preferred embodiment, the stirring cup includes a cup body and a cup base fixed to the bottom of the cup body, and the detection device is fixed in the cup base;

[0013] In a preferred embodiment, the detection device is fixed in the host computer.

[0014] Whether the detection device is fixed to the cup holder of the mixing cup or in the main unit, it can sense the detection element to intelligently detect the installation status of the mixing blade assembly. Fixing the detection element in the cup holder of the mixing cup can shorten the detection distance between the detection element and the detection device, improving detection sensitivity; fixing the detection device in the main unit makes it easier to rinse the mixing cup separately, reducing the risk of water entering the detection element during the cleaning process. Moreover, the control board is usually in the main unit, simplifying the connection between the detection device and the control board.

[0015] In a preferred embodiment, a lower attracting magnet is fixed to the outer bottom wall of the stirring cup, and an upper attracting magnet is fixed to the blade holder. After the blade holder is installed in place, the upper attracting magnet and the lower attracting magnet attract each other, and the upper attracting magnet forms the detection element.

[0016] By incorporating a lower and upper attracting magnet, the upper and lower attracting magnets are engaged, allowing the stirring blade assembly to adhere to the bottom wall of the mixing cup. During the pouring process, the stirring blade assembly will not detach from the bottom wall of the mixing cup, improving user safety. When it is necessary to remove the stirring blade assembly, the user only needs to overcome the attraction between the upper and lower attracting magnets, without affecting the flexible disassembly of the stirring blade assembly. The detection element is formed using the upper attracting magnet, achieving structural reuse, simplifying the structure, and reducing the cost of separately installing a detection magnet.

[0017] In a preferred embodiment, the power drive device includes a motor and a drive disk driven by the motor to rotate the transmission disk, with a magnetically conductive insulating rib provided between the drive disk and the detection device. More preferably, the drive disk is located below or on the outer periphery of the transmission disk.

[0018] More preferably, the host is provided with a mounting bracket for fixing the detection device, and the magnetic isolation rib is fixed to the mounting bracket.

[0019] By employing a motor and a drive disk driven by the motor, magnets with opposite magnetic poles are alternately arranged circumferentially on the drive disk. The magnetic poles of the transmission disk and the drive disk cooperate to achieve rotation. The power drive device has a simple structure and reliable transmission. Magnetic isolation ribs are set between the drive disk and the detection device to effectively prevent the magnetic field of the drive disk from interfering with the detection device's detection, thereby improving the accuracy of the detection device in detecting the tool holder's installation status.

[0020] By fixing the isolation ribs to the mounting bracket, a compact layout of the structure is achieved, reducing the space occupied by the main unit.

[0021] In a preferred embodiment, the power drive device includes an electromagnetic drive device, which includes a stator core and a coil winding wound around the stator core. When the electromagnetic drive device is energized, it generates a changing magnetic field to drive the transmission disk to rotate.

[0022] By setting the power drive device as a stator core and a coil winding, the coil winding is energized and works with the stator core to form a magnetic field. The transmission disk rotates in conjunction with the magnetic field, thus achieving reliable transmission.

[0023] Alternatively, the stator core may be located below or on the outer periphery of the drive disk.

[0024] In a preferred embodiment, the detection element is a detection magnet, and the detection device includes a reed switch;

[0025] A reed switch and a detection magnet are used to detect the position of the tool holder. Since there are multiple detection devices on the outer periphery of the tool holder, the installation state of the tool holder can be determined based on the number of detection devices that sense a signal, thus detecting whether the tool holder is installed flat. When every reed switch on the outer periphery of the tool holder detects its corresponding detection magnet, it indicates that the tool holder is installed and placed flat. If one reed switch detects a detection magnet but another does not, it is determined that the tool holder is installed but not flat. When no reed switch detects a detection magnet, the tool holder is not installed.

[0026] In a preferred embodiment, the detection element is a shielding portion located at the top of the tool holder, and the detection device includes an infrared sensor. Optionally, the shielding portion is the top of the peripheral wall of the tool holder.

[0027] By employing a shielding part in conjunction with an infrared sensor, the different states of the tool holder are detected by whether the infrared sensor is blocked by the shielding part. For example, if the shielding part does not block any infrared sensor, it is determined that the tool assembly is stably installed in place. If any infrared sensor is blocked by the shielding part, it indicates that the tool holder is tilted or one side is raised, and it is determined that the tool holder is installed but not flat in place.

[0028] In a preferred embodiment, the food processing machine includes a first detection device, a second detection device, and a third detection device, wherein the first detection device and the second detection device are arranged symmetrically about the center point of the blade holder.

[0029] Alternatively, the food processing machine may include a first detection device, a second detection device, a third detection device, and a fourth detection device, wherein the first and second detection devices are arranged symmetrically with respect to the diameter of the blade holder, and the third and fourth detection devices are arranged symmetrically with respect to the same diameter of the blade holder.

[0030] By setting up at least a first detection device, a second detection device, and a third detection device, a plane is defined using three points. Therefore, by detecting three points on the same plane of the tool holder, accurate detection of whether the tool holder is installed flat can be achieved. Reliability is further enhanced by symmetrically arranging at least two of the aforementioned detection devices. Even if one detection device fails, the installation of the agitator can still be detected using the other detection devices, resulting in high reliability. Attached Figure Description

[0040] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0044] like Figure 1-5 As shown, in one embodiment of the present invention, a food processing machine is provided, including a main unit 10, a mixing cup 20 installed on the main unit 10, and a mixing blade assembly 30 detachably installed in the mixing cup 20. The mixing blade assembly 30 includes a blade holder 31, a transmission disk 32 rotatably installed in the blade holder 31, and a blade 33 located above the blade holder 31. The transmission disk 32 is fixed with a transmission shaft 34 that passes through the blade holder 31 and is connected to the blade 33. The main unit 10 is provided with a power drive device for driving the transmission disk 32. The power drive device drives the transmission disk 32 to rotate remotely. The blade holder 31 is circumferentially arranged with detection elements 40. The food processing machine includes a plurality of detection devices 50 located outside the mixing cup 20 and spaced apart on the outer periphery of the blade holder 31 (that is, the outer periphery of the detection elements). Each detection device 50 cooperates with the detection element 40 to detect the position of the detection element 40.

[0045] This invention provides a food processing machine that uses a power drive device to drive the transmission disk 32 to rotate remotely, thereby achieving remote driving of the stirring blade assembly 30. The stirring blade assembly 30 is detachably installed inside the stirring cup 20, making cleaning convenient and simplifying the structure of the stirring cup 20. Furthermore, by arranging detection elements 40 circumferentially on the blade holder 31, the food processing machine includes multiple detection devices 50 located outside the stirring cup 20 and spaced apart on the outer periphery of the blade holder 31. Each detection device 50 cooperates with the detection element 40 to detect the position of the detection element 40. Therefore, when each detection device 50 detects the signal from the detection element 40, since the detection device 50 surrounds the outer periphery of the blade holder 31, meaning the blade holder 31 is placed flat on the mixing cup 20 without being tilted or raised due to obstructions such as particles, the coordinated detection of multiple detection devices not only achieves intelligent detection of whether the blade holder is installed, but also avoids the detection error of misjudging installation as correct due to blade holder tilt. This ensures accurate detection of whether the blade holder 31 is flat and properly installed, and achieves intelligent identification of the blade holder 31's installation status. This avoids machine noise and safety risks caused by users starting the machine directly even if the blade holder 31 is installed but tilted or not properly flat. Thus, the food processing machine becomes intelligent, improving transmission reliability, reducing operating noise, enhancing safety, and improving the user experience.

[0046] In addition, since multiple detection devices 50 are arranged at intervals around the outer periphery of the tool holder 31, when the tool holder is installed at an angle, the detection element 40 and the detection device 50 differ significantly not only in radial distance from the tool holder when it is installed flat, but also in axial distance. Therefore, compared with the method of setting the detection device 50 below the tool holder 31 and corresponding to the detection element, this method can achieve accurate detection of whether the tool holder is installed flat, and further reduce detection error.

[0047] In a preferred embodiment, the detection element 40 is a detection magnet, and the detection device 50 includes a linear Hall element.

[0048] By setting the detection element 40 as a detection magnet and the detection device 50 using a linear Hall element, the magnetic field strength is different when the distance between the detection magnet and the linear Hall element is different. The linear Hall element will emit signals of different strengths. In other words, the detection signals of the knife holder 31 in the three states of being installed in place, not installed, and installed on the mixing cup 20 but not flat are significantly different. In particular, the signal difference between the knife holder 31 not installed and the uneven installation state is amplified, making the detection of whether the knife holder 31 is flat and installed in place more sensitive and accurate.

[0049] Furthermore, by employing a linear Hall element, the magnetic field strength varies depending on the distance between the detection magnet and the linear Hall element, causing the linear Hall element to emit signals of varying strengths. Therefore, when the linear Hall element detects a small deviation between the distance of the detection magnet and the installation position, the tool holder can be leveled and positioned by the drive of the power drive device.

[0050] Of course, the structure of the detection element and the detection device is not limited to the one described above. In another preferred embodiment, the detection element 40 is a detection magnet and the detection device 50 includes a reed switch.

[0051] In another preferred embodiment, the detection element 40 is a shielding portion located on the top of the tool holder 31, and the detection device 50 includes an infrared sensor. Optionally, the shielding portion is the top of the peripheral wall of the tool holder 31.

[0052] The position detection of the tool holder 31 is achieved by using reed switches in conjunction with detection magnets. Since there are multiple detection devices 50 around the tool holder 31, the different installation states of the tool holder 31 can be determined based on the number of detection devices 50 that sense signals, thus detecting whether the tool holder 31 is installed flat. When every reed switch around the tool holder 31 detects its corresponding detection magnet, it indicates that the tool holder 31 is installed and placed flat. If one reed switch detects the detection magnet but another does not, it is determined that the tool holder 31 is installed but not flat. If no reed switch detects the detection magnet, the tool holder 31 is not installed.

[0053] By employing a shielding part in conjunction with an infrared sensor, the different states of the tool holder 31 can be detected by whether the infrared sensor is blocked by the shielding part. For example, if the shielding part does not block any infrared sensor, it is determined that the tool assembly is stably installed in place. If any infrared sensor is blocked by the shielding part, it indicates that the tool holder 31 is tilted or one side is raised, and it is determined that the tool holder 31 is installed but not flat in place.

[0054] It should also be noted that the food processing machine of this utility model may optionally include multiple replacement mixing blade assemblies installed in the mixing cup. By setting the shielding parts of different mixing blade assemblies at different heights, the infrared sensor can also detect the signal at the highest point of the shielding part of the detection element in different mixing blade assemblies, thereby realizing the identification of different mixing blade assembly types and enabling the food processing machine to match the corresponding working mode based on the type of mixing blade assembly.

[0055] Of course, if the detection element is a detection magnet, the number and position of the detection elements in different stirring blade assemblies can be set differently to identify different stirring blade assembly types, so that the food processing machine can match the corresponding working mode based on the stirring blade assembly type.

[0056] In a preferred embodiment, such as Figure 2 As shown, the detection element 40 is ring-shaped.

[0057] By setting the detection element 40 as a ring, the tool holder 31 can be installed at multiple angles. Regardless of the installation angle, after installation, multiple detection devices 50 can be used to check whether the installation is flat. Moreover, the ring-shaped detection element 40 can avoid the situation where the detection device 50 cannot effectively detect due to the misalignment of the tool holder 31, reduce the detection blind zone, and improve the accuracy of detection.

[0058] Of course, in other embodiments, multiple detection elements 40 may be arranged at intervals along the circumference of the tool holder 31, and the number of detection elements 40 shall not be less than the number of detection devices 50.

[0059] For example, six detection elements 40 and three detection devices 50 are provided. While realizing triple detection by the three detection devices 50, the tool holder 31 can also be installed in multiple positions.

[0060] In a preferred embodiment, such as Figure 1 , 3 As shown, the stirring cup 20 includes a cup body 21 and a cup base 22 fixed to the bottom of the cup body, and the detection device 50 is fixed in the cup base 22.

[0061] In another preferred embodiment, the detection device 50 is fixed in the host 10.

[0062] Specifically, an upward-protruding annular mounting platform is provided on the top of the main unit 10. The mounting platform is located on the outer periphery of the mixing cup and radially limits the mixing cup. The detection device 50 is located inside the mounting platform.

[0063] Whether the detection device 50 is fixed in the cup holder of the mixing cup 20 or in the main unit 10, it can sense the detection element 40 to intelligently detect the installation status of the stirring blade assembly 30. Fixing the detection element 40 in the cup holder of the mixing cup 20 can shorten the detection distance between the detection element 40 and the detection device 50, improving detection sensitivity; fixing the detection device 50 in the main unit 10 makes it easier to rinse the mixing cup 20 separately, reducing the risk of water entering the detection element 40 during the cleaning process. Moreover, since the control board is usually in the main unit 10, the connection between the detection device 50 and the control board is simple.

[0064] In a preferred embodiment, such as Figure 4 As shown, a lower attracting magnet 70 is fixed to the outer bottom wall of the stirring cup 20, and an upper attracting magnet 80 is fixed to the knife holder 31. After the knife holder 31 is installed in place, the upper attracting magnet 80 and the lower attracting magnet 70 attract each other, and the upper attracting magnet 80 forms the detection element 40.

[0065] By setting a lower attracting magnet 70 and an upper attracting magnet 80, the upper attracting magnet 80 and the lower attracting magnet 70 are attracted to each other, allowing the stirring blade assembly 30 to be attracted to the bottom wall of the stirring cup 20. During the pouring process, the stirring blade assembly 30 will not detach from the bottom wall of the stirring cup 20 on its own, improving user safety. When it is necessary to remove the stirring blade assembly 30, the user only needs to overcome the attraction of the upper attracting magnet 80 and the lower attracting magnet 70, without affecting the flexible disassembly of the stirring blade assembly 30. The upper attracting magnet 80 forms a detection element 40, realizing structural reuse, simplifying the structure, and reducing the cost of setting up a separate detection magnet.

[0066] This invention does not limit the specific structure of the power drive device; for example, in a preferred embodiment, such as... Figure 1-5 As shown, the power drive device includes a motor 11 and a drive disk 12 driven by the motor 11 to rotate the transmission disk 32. A magnetically conductive isolation rib 61 is provided between the drive disk 12 and the detection device 50. More preferably, the drive disk 12 is located below or on the outer periphery of the transmission disk 32.

[0067] More preferably, the host 10 is provided with a mounting bracket 60 for fixing the detection device 50, and the magnetic isolation rib 61 is fixed to the mounting bracket 60. The mounting bracket 60 is preferably a plastic bracket to reduce costs, and the magnetic isolation rib 61 is a metal part, such as a ring-shaped metal sheet. As a magnetic isolation rib, it can focus and guide the magnetic field lines in all directions, and more effectively improve the transmission reliability of the drive disk and the detection reliability of the detection device.

[0068] By employing a motor 11 and a drive disk 12 driven by the motor 11, with magnets of opposite magnetic poles alternately arranged circumferentially on the drive disk 12, the transmission disk 32 rotates in coordination with the magnetic poles of the drive disk 12. The power drive device has a simple structure and reliable transmission. A magnetically conductive isolation rib 61 is provided between the drive disk 12 and the detection device 50 to effectively prevent the magnetic field of the drive disk 12 from interfering with the detection of the detection device 50, thereby improving the accuracy of the detection device 50 in detecting the installation status of the tool holder 31.

[0069] By fixing the isolation ribs to the mounting bracket 60, a compact layout of the structure is achieved, reducing the space occupied by the main unit 10.

[0070] In another preferred embodiment, the power drive device includes an electromagnetic drive device, which includes a stator core and a coil winding wound around the stator core. When the electromagnetic drive device is energized, it generates a changing magnetic field to drive the transmission disk 32 to rotate.

[0071] By setting the power drive device as a stator core and a coil winding, the coil winding is energized and works with the stator core to form a magnetic field. The transmission disk 32 rotates in conjunction with the magnetic field, thus achieving reliable transmission.

[0072] Optionally, the stator core is located below the drive disk 32. Of course, the stator core can also be located on the outer periphery of the drive disk 32, for example, by setting an upward-extending annular mounting platform on the host, and fixing the drive disk inside the annular mounting platform.

[0073] In a preferred embodiment, such as Figure 2 As shown, the food processing machine includes a first detection device 51, a second detection device 52, a third detection device 53, and a fourth detection device 54. The first detection device 51 and the second detection device 52 are arranged symmetrically with respect to the diameter of the drive disk 12, while the third detection device 53 and the fourth detection device 54 are arranged symmetrically with respect to the same diameter of the drive disk 12.

[0074] In another preferred embodiment, the food processing machine includes a first detection device, a second detection device, and a third detection device, wherein the first detection device and the second detection device are arranged symmetrically about the center point of the blade holder.

[0075] By setting up at least a first detection device, a second detection device, and a third detection device, a plane is defined using three points. Therefore, by detecting three points on the same plane of the tool holder, accurate detection of whether the tool holder is installed flat can be achieved. Reliability is further enhanced by symmetrically arranging at least two of the aforementioned detection devices. Even if one detection device fails, the installation of the agitator can still be detected using the other detection devices, resulting in high reliability.

[0076] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0077] 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.

[0078] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
