Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, and in particular to a reliable food processing machine. Background Technology
[0002] Food processors for making beverages include a cup body and a lid. The lid is screwed onto the cup body, and the lid and cup body together form a mixing chamber. A stirring device is also located at the bottom of the cup body for making beverages such as soy milk, juice, milk tea, and rice paste. To prevent the stirring device from rotating and causing injury when the lid is open, national standards require that the stirring device can only be activated when the lid is closed, and must stop rotating when the lid is open. Therefore, food processors are generally equipped with a detection device to check if the lid is properly installed. Furthermore, to improve the stirring effect, baffles are usually installed on the inner wall of the cup body or lid. During stirring, the rotating liquid impacts these baffles, disrupting the original stable rotation pattern and further breaking down particles in the beverage, thus improving its texture. However, the motor inside the food processor vibrates when it drives the mixing device to rotate. Also, when the slurry hits the baffles during operation, it vibrates. As a result, the lid may move relative to the cup body due to the vibration, causing the lid to detach from the cup body. The corresponding detection device will then be unable to detect the lid, resulting in the food processor being unable to make beverages and causing inconvenience to the user.
[0003] Based on this, existing technology CN201821586969.1 discloses a method that incorporates a flexible anti-retraction structure within the handle and a limiting structure on the screw-on component of the lid. When the lid is screwed onto the cup body, the screw-on component directly engages with the safety switch, activating the safety switch. Simultaneously, the flexible anti-retraction structure within the handle engages with the limiting notch on the screw-on component of the lid, locking the lid in place. This structure effectively solves the problem of power outages caused by relative movement between the lid and the cup body due to vibration during operation. However, in this solution, the flexible anti-retraction structure on the handle engages with the screw-on component of the lid. Due to the limited space on the screw-on component, users need to exert greater force to remove the lid, overcoming both the friction between the flexible anti-retraction structure and the limiting notch, as well as the friction between the screw-on component and the safety switch. This makes operation difficult for users, and in severe cases, may even cause deformation or breakage of the screw-on component. At the same time, since the screw-on part on the lid is also used to connect with the safety switch, when cleaning the cup, the cleaning water may enter the handle through the elastic anti-reverse structure, causing water to enter the safety switch and leading to abnormal problems.
[0004] Therefore, based on product performance and safety considerations, the safety switch in the above structure is not directly connected to the high-voltage line. Instead, the safety switch is connected to the low-voltage line and indirectly controls the high-voltage components by sending a signal to the control device. However, this method does not meet the national standard requirements for the power-off of high-voltage components in food processing machines. Furthermore, when the control device malfunctions, it will be unable to power off the high-voltage components, and users will still face safety risks. Utility Model Content
[0005] The purpose of this invention is to provide a reliable food processing machine that can effectively solve the problems of existing technology, such as laborious operation, water ingress and electrical leakage in the handle, and safety risks of abnormal use, as well as the inability to effectively guarantee the reliable operation of the food processing machine.

[0009] Furthermore, a second positioning hole is provided on the bottom wall of the mounting cavity, which is opposite to and penetrates the locking groove. The elastic locking pin includes a compression spring and a locking pin. The front end of the locking pin passes through the second positioning hole and extends into the locking groove. The rear end of the compression spring abuts against the inner surface of the top wall of the cover plate, and the front end of the compression spring abuts against the locking pin, so as to elastically press the locking pin into the second positioning hole.
[0010] Furthermore, the cover plate is provided with a first guide post having a hollow cavity on the side facing the mounting cavity, the rear end of the locking pin is provided with a groove, a second guide post is provided in the groove, the second guide post is inserted into the hollow cavity of the first guide post, and the compression spring is sleeved on the outside of the first guide post and the second guide post, with the front end of the compression spring positioned in the groove.
[0011] Alternatively, the cover plate may have a first guide post on the side facing the mounting cavity, the rear end of the locking pin may have a groove, a second guide post may be provided in the groove, the second guide post may have a hollow cavity, the first guide post may be inserted into the hollow cavity of the second guide post, and the compression spring may be fitted on the outside of the first and second guide posts, with the front end of the compression spring positioned in the groove.
[0012] Furthermore, the screw passes through the bottom of the cover base and is fixed to the cover plate, wherein the center line of the cup body, the center line of the elastic locking pin, and the center line of the screw are located on the same vertical plane.
[0013] Furthermore, located below the locking groove, the side wall of the handle is provided with a laterally open screw groove, and the cup lid is provided with a screw buckle protruding downward on the side opposite to the handle. The screw buckle is located below the elastic locking pin. The cup lid is rotatably installed on the cup body, so that the screw buckle is engaged in the screw groove, and the elastic locking pin slides along the upper end face of the handle to be inserted into the locking groove.
[0014] Furthermore, the upper end face of the handle has a sliding surface and an aligning surface located on both sides of the locking groove. During the rotation of the cup lid, the elastic locking pin abuts against the sliding surface and slides on the sliding surface. The aligning surface is used to align with the lower end face of the cup lid. The distance between the sliding surface and the lower end face of the cup lid is greater than the distance between the aligning surface and the lower end face of the cup lid.

[0018] By adopting the above-mentioned technical solution of this utility model, since a magnetic micro-switch is installed inside the handle and connected to the high-voltage circuit, and a first magnet is installed on the lid, when the lid is closed, the first magnet can trigger the magnetic micro-switch to conduct, thereby realizing the electrical connection of the high-voltage circuit. The control device can control the high-voltage components installed in the food processor. When the lid is opened due to accidental operation, the first magnet moves away from the magnetic micro-switch, and the magnetic micro-switch disconnects the power to the high-voltage circuit. The high-voltage components installed in the food processor are de-energized and stop working, solving the problem of the abnormal situation in the prior art where the high-voltage components cannot be de-energized due to the abnormality of the control device. This effectively ensures the safety of the user when the lid is open and also meets the national standard requirements for user personal safety. At the same time, the lid is also equipped with an elastic locking pin that cooperates with the locking groove on the handle. This allows the lid to be locked to the cup body by the elastic locking pin when the lid is closed, even if the machine vibrates during operation, thus effectively ensuring the reliability of the food processor during operation. More importantly, the magnetic micro switch connected to the high-voltage line in this invention is sealed inside the handle. Therefore, even during the cleaning of the cup, there is no risk of water ingress or electric leakage in the handle.

[0028] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings. It should be noted that while many specific details are set forth in the following description to provide a full understanding of this utility model, it can also be implemented in other ways different from those described herein. Therefore, the scope of protection of this utility model is not limited to the specific embodiments disclosed below.
[0029] by Figures 1 to 8 The food processing machine shown is a specific embodiment, which will be used to further describe the present invention in detail.
[0030] A food processing machine includes a base 1 and a detachable cup assembly mounted on the base 1. The cup assembly includes a cup body 2 and a lid 3 mounted on the cup body 2. A sealing ring 4 is fitted on the lower outer side of the lid 3. The lid 3 and the cup body 2 are enclosed by the sealing ring 4 to form a sealed pulping chamber. A motor (not shown in the figure) is installed inside the base 1, and a stirring device (not shown in the figure) is installed inside the cup body 2. The motor is driven by the stirring device through a coupling to drive the stirring device to rotate.
[0031] In this embodiment, the cup lid 3 is screwed onto the cup body 2, and the inner wall of the cup body 2 is provided with an inwardly protruding buckle 21 located above the sealing ring 4. The outer wall of the cup lid 3 is provided with a groove 31. When the cup lid 3 is screwed onto the cup body 2, the buckle 21 is engaged in the groove 31. This can prevent the user from easily opening the lid and causing safety risks, and also allows the user to pour the beverage without opening the lid. At the same time, in this embodiment, the groove 31 is also provided with a vent 32 that connects the pulping chamber to the outside. The vent 32 can be used to balance the air pressure inside and outside the pulping chamber. When the pressure inside the pulping chamber is too high, the air can be vented out through the vent 32.
[0032] In this embodiment, to improve the taste of the beverage, a baffle 33 is provided on the inner wall of the cup lid 3. The baffle 33 is used to disrupt the liquid flow during beverage preparation in the pulping chamber, improve the effect of the stirring device in crushing materials, and achieve a smoother taste when the user drinks it. In this embodiment, when the food processor is working, the rotation direction of the stirring device is opposite to the rotation direction of the cup lid 3 when it is closed.
[0033] Meanwhile, in this embodiment, a magnetically controlled micro switch 5 is sealed inside the handle 22 on one side of the cup body 2. The magnetically controlled micro switch 5 includes a micro switch 51 and a second magnet 52, with the second magnet 52 installed on the free end of the spring contact of the micro switch 51. The micro switch 51 is connected to the high-voltage circuit of the food processing machine, for example, to the neutral line between the control device and the motor, or between the control device and the heating element. Simultaneously, a first magnet 6 is provided on the side of the cup lid 3 opposite to the handle 22 to trigger the magnetically controlled micro switch 5 to conduct. When the cup lid 3 is installed on the cup body 2, the first magnet 6 and the second magnet 52 repel each other, causing the second magnet 52 to drive the spring contact to press against the contact of the micro switch 51, thereby enabling the micro switch 51 to conduct the neutral line. The cup lid 3 includes a lid base 34 and a lid plate 35. The lid base 34 and the lid plate 35 enclose a mounting cavity 30. A first positioning groove 301 is provided on the bottom wall of the mounting cavity 30. A pressing part 351 is provided on the lid plate 35. The pressing part 351 confines the first magnet 6 in the first positioning groove 301, so that the first magnet 6 is installed in the mounting cavity 30.
[0034] In addition, an elastic locking pin 7 is installed in the mounting cavity 30. The elastic locking pin 7 includes a compression spring 71 and a locking pin 72. A second positioning hole 302 is provided on the bottom wall of the mounting cavity 30. The front end of the compression spring 71 abuts against the locking pin 72, and the rear end of the compression spring 71 abuts against the inner surface of the top wall of the cover plate 35, thereby pressing the locking pin 72 into the second positioning hole 302. In this embodiment, a locking groove 220 is provided on the upper end face of the handle 22. When the cup lid 3 is installed on the cup body 2, the elastic locking pin 7 passes through the second positioning hole 302 and extends into the locking groove 220, so that the cup lid 3 is positioned on the cup body 2, and the first magnet 6 can trigger the magnetic micro switch 5 to conduct.
[0035] In this embodiment, a screw 8 is provided at the bottom of the cover base 34. The screw 8 passes through the bottom of the cover base 34 and is fixed to the cover plate 35, thus achieving a fixed connection between the cover plate 35 and the cover base 34. To prevent the food processor from swaying due to motor vibration during beverage preparation, this embodiment requires that the center line of the cup body 2, the center line of the elastic locking pin 7, and the center line of the screw 8 be located on the same vertical plane. This effectively reduces the swaying amplitude of the cup lid 3 relative to the cup body 2 during the operation of the food processor. Based on this connection method, in order to achieve a compact structural layout, the first magnet 6 and the elastic locking pin 7 located in the mounting cavity 30 need to be staggered. The first magnet 6 is installed on the side of the mounting cavity 30 away from the cup body 2.
[0036] Meanwhile, since the compression spring 71 is always in a taut compressed state, in order to prevent the compression spring 71 from disengaging from the locking pin 72, in this embodiment, a first guide post 352 is provided on the side of the cover plate 35 facing the mounting cavity 30, and the first guide post 352 has a hollow cavity. A groove 720 is provided at the rear end of the locking pin 72, and a second guide post 721 is provided in the groove 720. The second guide post 721 is inserted into the hollow cavity of the first guide post 352, and the compression spring 71 is fitted on the outside of the first guide post 352 and the second guide post 721. At the same time, the front end of the compression spring 71 is positioned in the groove 720. This can effectively prevent the compression spring 71 from disengaging due to the vibration of the food processing machine during operation.
[0037] Of course, the positioning structure for the compression spring is not limited to the above structure. For example, the cover plate is provided with a first guide post on the side facing the mounting cavity, the rear end of the locking pin is provided with a groove, the groove is provided with a second guide post, the second guide post has a hollow cavity, the first guide post is inserted into the hollow cavity of the second guide post, the compression spring is sleeved on the outside of the first guide post and the second guide post, and the front end of the compression spring is positioned in the groove.
[0038] In this embodiment, below the locking groove 220, the side wall of the handle 22 is provided with a laterally open screw-in groove 221. A screw-in buckle 36 protrudes downwards on the side of the cup lid 3 opposite to the handle 22, and the screw-in buckle 36 is located below the elastic locking pin 7. After the cup lid 3 is rotated and installed onto the cup body 2, the screw-in buckle 36 engages in the screw-in groove 221, and the elastic locking pin 7 slides along the upper surface of the handle 22 until it is inserted into the locking groove 220. The magnetic microswitch 5 is located within the receiving cavity 222 of the handle 22, and the receiving cavity 222 is isolated from and does not communicate with the screw-in groove 221. This effectively prevents external cleaning water from entering the receiving cavity through the screw-in groove during cup cleaning, thus preventing the magnetic microswitch from leaking water and causing electrical leakage. Meanwhile, in this embodiment, because the first magnet 6 is installed on the side of the cup lid 3 away from the cup body 2 and is offset from the elastic locking pin 7, the screw groove 221 on the handle and the magnetic micro switch 5 are also offset. This is conducive to the compact installation of the structure and prevents the handle from appearing too bulky and heavy, affecting the user's grip.
[0039] It should be noted that in this embodiment, the upper surface of the handle 22 has a sliding surface 223 and an aligning surface 224 located on both sides of the locking groove 220. During the rotation of the cup lid 3, the elastic locking pin 7 abuts against the sliding surface 223 and slides on the sliding surface 223. The aligning surface 224 is used to align with the lower end surface of the cup lid 3. The distance between the sliding surface 223 and the lower end surface of the cup lid 3 is greater than the distance between the aligning surface 224 and the lower end surface of the cup lid. This arrangement is adopted to reduce the stroke of the elastic locking pin, allowing users to better install and remove the cup lid, avoiding the problem of the elastic locking pin getting stuck, and making it easier for users. On the other hand, it is also to prevent a large gap between the cup lid and the cup body after the cup lid is installed, which would affect the aesthetics of the product. Of course, to facilitate the installation of the cup lid, the end of the elastic locking pin and the sliding surface need to be made into a curved or inclined surface that is easier to slide.
[0040] With the food processing machine structure described in this embodiment, a magnetic microswitch connected to the high-voltage circuit is installed inside the handle, and a first magnet is installed on the lid. When the lid is closed, the first magnet triggers the magnetic microswitch to conduct, thus connecting the high-voltage circuit. The control device can then control the high-voltage components inside the food processing machine. When the lid is accidentally opened, the first magnet moves away from the magnetic microswitch, which then disconnects the high-voltage circuit. The high-voltage components inside the food processing machine are de-energized and cease operation. This solves the problem of existing technologies where abnormalities in the control device prevent the high-voltage components from being de-energized, effectively ensuring user safety when the lid is open and meeting national standards for user safety. Furthermore, the lid is equipped with a spring-loaded locking pin that engages with the locking groove on the handle. This ensures that even if the machine vibrates while closed, the lid remains locked to the cup body, preventing movement and effectively guaranteeing the reliability of the food processing machine during operation. More importantly, in this embodiment, the magnetic micro switch connected to the high-voltage line is sealed inside the handle. Therefore, even during the cleaning of the cup, there is no risk of water ingress or electric leakage in the handle. Compared with the prior art, this embodiment can effectively ensure the waterproof safety of the magnetic micro switch inside the handle.
[0041] It should be noted that this invention addresses the technical problem in existing food processors where the rotating agitator causes the liquid flow to rotate, resulting in circumferential displacement of the lid relative to the cup body. This leads to unreliable operation due to power outages, safety risks such as water leakage and electric shock during cleaning due to water entering the handle, and the difficulty in removing the lid from existing food processors. Therefore, the installation method of the lid and cup body in this invention is not limited to a rotating snap-fit installation. The conventional method of directly inserting the lid into the cup body is also applicable to this invention.
[0042] It should also be noted that in this embodiment, the first magnet and the second magnet are magnetically coupled in a non-displaced manner, which can achieve a sealed and waterproof microswitch. The magnetic coupling method between the first magnet and the second magnet is not limited to the repulsive scheme of this embodiment. Through reasonable structural changes, the first magnet and the second magnet can also be magnetically attracted to achieve the power-off function of the microswitch.
[0043] Furthermore, for the food processing machine in this embodiment, the cup body can adopt either a double-layer cup structure or a single-layer cup structure. The connection between the handle and the cup body can be either integrally molded or separately installed. The cup body structure and materials used in the prior art can also be used in the cup body of this utility model.
[0044] Furthermore, it should be noted that the food processor of this invention can be used to make beverages such as soy milk that require the grinding of ingredients; therefore, the stirring device can be a grinding blade. Of course, the food processor of this invention can also be used to make beverages that do not require grinding, such as milk tea. A tea basket is placed inside the cup, and tea pieces are placed in the basket. The stirring device is then used to rotate the liquid flow to disperse and extract the tea beverage in the basket. Moreover, the structural form of the food processor of this invention is not limited to the solution provided in this embodiment. The food processor of this invention can also be a bottom-mounted food processor where the motor is directly fixed to the cup body, forming an integral part of the cup body; it can also be a hand-washable food processor with automatic water intake and drainage; or even a top-mounted food processor where the motor is installed inside the cup lid, and the motor-driven shaft extends directly into the cup body and is connected to the stirring device.
[0045] Those skilled in the art will understand that this invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this invention will be included within the scope of the claims.
