Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more particularly to a food processing machine. Background Technology

[0002] Some existing soymilk makers have an anti-overflow electrode in the lid. The detection principle of this anti-overflow electrode is as follows: the body of the soymilk maker is usually made of stainless steel and grounded. When the soymilk in the body boils and rises to the preset anti-overflow level, the soymilk comes into contact with the detection end of the anti-overflow electrode, making the anti-overflow electrode connected to the ground signal, thereby generating a ground signal, which is also the anti-overflow signal, and transmitting it to the control device to realize the identification of the anti-overflow status.

[0003] In the process of developing a soymilk maker, the applicant designed an anti-overflow electrode to be installed on the cup lid, and the cup lid has a protrusion extending outward. A conductive rod connected to the anti-overflow electrode is installed in the protrusion. At the same time, a handle is provided on the outside of the cup body. The handle includes a handle cover and a handle seat, and an installation cavity is formed between the handle cover and the handle seat. A coupling component connected to the control device is provided in the installation cavity. When the cup lid is fastened to the cup body, the conductive rod is inserted into the installation cavity and coupled with the coupling component to transmit an anti-overflow signal to the control device.

[0004] To enhance the appearance of the soy milk maker, a decorative ring is fitted on the top of the cup. The outer surface of the decorative ring is electroplated, and the electroplating layer contacts the top of the cup. This decorative ring is located between the cup and the handle base, and the decorative ring, handle cover, and handle base are fixed together with screws.

[0005] During the research and development process, the applicant discovered that the decorative ring, handle cover, and handle base are fixed together with screws, resulting in assembly gaps between the decorative ring and handle base, as well as between the handle cover and handle base. Water remaining after cleaning the soymilk maker, or water condensed from steam during processing, can enter the gap between the decorative ring and handle base and come into contact with the screws. Simultaneously, water can also enter the mounting cavity and flow into the gap between the handle cover and handle base, contacting the screws. When the soymilk maker is operated under these conditions, the conductive rod inserted into the mounting cavity will connect to the cup body (which is grounded) through the water in the mounting cavity, the water in the gap between the handle cover and handle base, the screws, the water in the gap between the decorative ring and handle base, and the electroplated layer. In this situation, the conductive rod will generate a grounding signal, which will be transmitted to the control device through a coupling component. The control device, upon receiving the grounding signal, will interpret it as an anti-overflow signal and terminate the current program to perform anti-overflow processing. However, the liquid level in the cup body has not reached the preset anti-overflow level, leading to a false anti-overflow judgment. This causes the heating element of the food processor to stop heating, resulting in the food not being cooked. Utility Model Content

[0006] This application provides a food processing machine to solve the problem of water entering the gap between the decorative ring and the handle seat, as well as the gap between the handle cover and the handle seat, causing false overflow prevention.

[0007] This application provides a food processing machine, including a metal cup body and a cup lid fastened to the metal cup body. The cup lid is provided with an anti-overflow electrode and a conductive rod communicating with the anti-overflow electrode. A handle is provided on one side of the metal cup body. The handle includes a handle seat located on one side of the metal cup body and a handle cover installed on the handle seat. The handle seat has a mounting cavity, and a coupling component is provided in the mounting cavity. The coupling component is connected to a control device. The anti-overflow electrode is inserted and coupled to the coupling component through the conductive rod. A decorative ring is installed between the handle seat and the metal cup body. The decorative ring, the handle seat, and the handle cover are fixed together by screws. The decorative ring is plated with an electroplated layer on the surface of the handle. The top of the decorative ring presses against the flange of the metal cup body through the electroplated layer. An insulating component is provided in the gap between the decorative ring and the handle seat. The insulating component is used to isolate the electroplated layer from the screws.

[0008] Compared to existing technologies where water ingress can lead to false overflow detection due to gaps between the decorative ring and handle seat, and between the handle cover and handle seat, this application addresses this issue by installing an insulating component within the gap between the decorative ring and handle seat. This isolates the electroplated layer from the screw, thus isolating the electroplated layer from the mounting cavity and its conductive rod and coupling components. This prevents water from entering the gap between the decorative ring and handle seat. Furthermore, even if water does enter the mounting cavity, the isolation between the electroplated layer and the screw prevents the conductive rod from connecting to the electroplated layer via water or the screw, thus avoiding electrical connection with the cup body and the generation of a grounding signal. Consequently, the control device will not receive a false overflow signal, preventing false overflow detection, improving overflow detection accuracy, ensuring smooth food processing, and preventing undercooked food.

[0009] As a preferred technical solution, the insulating component is formed by curing insulating adhesive injected into the gap.

[0010] By injecting insulating adhesive into the gaps, the gaps can be effectively sealed, and after curing, the electroplated layer of the decorative ring and the screws can be isolated.

[0011] As a preferred technical solution, the insulating component is an insulating silicone component, which is clamped and fixed by the decorative ring and the handle base.

[0012] As an alternative, the insulating component is an insulating silicone component, which can be sandwiched between the decorative ring and the handle base during the assembly of the decorative ring and the handle base. Then, during the process of fixing the decorative ring, the handle base and the handle cover with screws, the insulating silicone component is squeezed and pressed, so that the insulating silicone component completely seals the gap and achieves isolation between the electroplated layer of the decorative ring and the screw.

[0013] As a preferred technical solution, the decorative ring has a mating groove on the side facing the handle seat. The mating groove is connected to the electroplated layer through a step. The end face of the handle seat abuts the insulating component in the mating groove, and the top of the handle seat abuts the step.

[0014] By setting a mating groove on one side of the decorative ring, and connecting the mating groove to the electroplated layer through a step, the decorative ring can be positioned for easy installation. On the other hand, the end face of the handle base abuts the insulating part in the mating groove, so that the insulating part can be hidden in the mating groove, making the food processing machine more aesthetically pleasing.

[0015] As a preferred technical solution, the upper end of the insulating member extends to the top of the handle seat and is held in place by the step.

[0016] Furthermore, the insulating element extends to the top of the handle base and has a stepped support, so that the insulating element also seals the gap between the handle base and the step, further improving the isolation stability between the electroplated layer of the decorative ring and the screw.

[0017] As a preferred technical solution, the bottom of the handle base is provided with a drainage hole, through which water flowing into the mounting cavity is discharged.

[0018] By setting a drainage hole at the bottom of the handle base, water entering the mounting cavity can be quickly discharged from the handle base, thereby reducing the impact of water on the conductive rod and coupling components inside the mounting cavity.

[0019] As a preferred technical solution, the handle seat is provided with a positioning groove on the side near the metal cup body, and a portion of the lower end of the decorative ring is installed in the positioning groove.

[0020] The installation of the decorative ring is made more convenient by setting a positioning groove on the handle base. At the same time, the handle base supports the decorative ring through the positioning groove, which improves the stability of the installation of the decorative ring.

[0021] As a preferred technical solution, the food processing machine further includes a housing, the metal cup body is placed inside the housing, the handle seat is integrally formed into the housing, the top of the housing is provided with an annular slot, the lower end of the decorative ring is provided with an annular insertion part, and the annular insertion part is inserted into the annular slot.

[0022] The decorative ring is inserted into the annular slot of the outer shell through the annular plug at the lower end, and the decorative ring is placed in the positioning groove, which further improves the installation stability of the decorative ring.

[0023] As a preferred technical solution, the handle seat has a mounting hole at one end facing the decorative ring, a waterproof plug is interference-fitted into the mounting hole, a through hole is opened in the center of the waterproof plug, and the wire of the coupling component passes through the through hole and is connected to the control device.

[0024] By installing a waterproof plug, moisture can be prevented from entering the food processing machine along with the wires of the coupling component, thus avoiding interference with the control device.

[0025] As a preferred technical solution, the coupling component includes a first spring and a second spring, both of which are electrically connected to the control device. After the cup lid is installed in place, the conductive rod is inserted between the first spring and the second spring and abuts against the first spring and the second spring, so that the conductive rod is coupled to the coupling component.

[0042] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0045] This application provides a food processing machine, such as... Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the structure of the food processing machine described in the embodiments of this application. Figure 2 This is an exploded view of the food processing machine described in the embodiments of this application. Figure 3 This is a schematic diagram of the food processor described in this application embodiment, showing an anti-overflow electrode 21. The food processor includes a metal cup body 1, a cup lid 2, a handle 3, and a decorative ring 4. The metal cup body 1 is used to hold food ingredients and has a crushing device inside to process the food ingredients.

[0046] like Figure 2 and Figure 3 As shown, the cup lid 2 is fastened to the metal cup body 1, and the cup lid 2 is provided with an anti-overflow electrode 21 and a conductive rod 22 communicating with the anti-overflow electrode 21. The cup lid 2 extends outward with a cup lid protrusion 23, and a mounting cover 24 is installed below the cup lid protrusion 23. A cavity for placing the conductive rod 22 is formed between the cup lid protrusion 23 and the mounting cover 24. The anti-overflow electrode 21 has a detection end, which is exposed inside the metal cup body 1.

[0047] The handle 3 is disposed on one side of the metal cup body 1, and the handle 3 includes a handle base 31 and a handle cover 32 located on one side of the metal cup body 1. The handle cover 32 and the handle base 31 are fixedly connected by screws 5. For example, one end of the handle cover 32 can be inserted into the handle base 31. For instance, the handle base 31 is provided with a mounting cavity 311, and one end of the handle cover 32 is provided with a plug-in part 321. The plug-in part 321 is inserted into the mounting cavity 311, and the plug-in part 321 forms a screw hole. The screw 5 passes through the handle base 31 and is connected to the screw hole.

[0048] Furthermore, a coupling component 6 is installed in the mounting cavity 311 of the handle seat 31. The coupling component 6 is fixed by connecting the handle cover 32 to the handle seat 31, and the coupling component 6 is connected to the control device of the food processing machine. When the cup cover 2 is fastened to the metal cup body 1, the anti-overflow electrode 21 is coupled to the coupling component 6 through the conductive rod 22. When the slurry in the metal cup body 1 boils and rises to the preset anti-overflow level, the slurry contacts the detection end of the anti-overflow electrode 21, and the metal cup body 1 is grounded. At this time, the anti-overflow electrode 21 is connected to the ground signal, thereby generating a ground signal, which is also an anti-overflow signal, and is transmitted to the control device through the coupling component 6 to realize the identification of the anti-overflow status.

[0049] In one technical solution, the conductive rod 22 extends circumferentially along the cup lid 2, and the handle seat 31 is also provided with an opening 312 communicating with the mounting cavity 311. When the cup lid 2 is fastened to the metal cup body 1, the cup lid 2 is rotated, and the conductive rod 22 will pass through the opening 312 and be placed in the mounting cavity 311, and be inserted and coupled with the coupling component 6.

[0050] In this embodiment, the decorative ring 4 is disposed between the metal cup body 1 and the handle base 31, specifically, as shown in the example below. Figure 4 and Figure 5 As shown, Figure 4 This is a cross-sectional view of the food processing machine described in the embodiments of this application. Figure 5 Examples of this application Figure 4 An enlarged schematic diagram at point A. The decorative ring 4, handle base 31, and handle cover 32 are fixed together by screws 5, which pass through the inner wall of the decorative ring 4 and handle base 31 before being fixed to the handle cover 32. The surface of the decorative ring 4 exposed on the handle 3 is plated with an electroplated layer, and the top of the decorative ring 4 presses against the flange 11 of the metal cup body 1 through the electroplated layer.

[0051] During the development of the aforementioned food processing machine, the applicant discovered that because the decorative ring 4, handle cover 32, and handle base 31 are fixedly connected by screws 5, assembly gaps exist between the decorative ring 4 and handle base 31, as well as between the handle cover 32 and handle base 31. Water remaining after cleaning the food processing machine, or water vapor condensing during processing, can enter the gap between the decorative ring 4 and handle base 31 and come into contact with the screws 5. There is also a possibility that water can enter the mounting cavity 311 and flow into the gap between the handle cover 32 and handle base 31, also coming into contact with the screws 5. When the food processor is operated under the above conditions, the conductive rod 22 inserted into the mounting cavity 311 will connect to the metal cup 1 (at this time, the metal cup 1 is in a grounded state) through the water in the mounting cavity 311, the water in the gap between the handle cover 32 and the handle seat 31, the screw 5, the water in the gap between the decorative ring 4 and the handle seat 31, and the electroplating layer. In this case, the conductive rod 22 will generate a grounding signal and transmit it to the control device through the coupling component 6. The control device will take the grounding signal as an anti-overflow signal and stop the current program to perform anti-overflow processing. At this time, the liquid level in the cup has not reached the preset anti-overflow level, resulting in a false anti-overflow judgment, causing the heating element of the food processor to stop heating and the food to be undercooked.

[0052] To address the aforementioned issues, this embodiment of the application incorporates an insulating element 7 within the gap between the decorative ring 4 and the handle seat 31. This isolates the electroplated layer from the screw 5, thereby isolating the electroplated layer from the mounting cavity 311 and its conductive rod 22 and coupling component 6. On one hand, water (such as residual water after cleaning the food processor or water generated by the condensation of steam during food processing) will not enter the gap between the decorative ring 4 and the handle seat 31. On the other hand, even if water enters the mounting cavity 311, because the electroplated layer of the decorative ring 4 is isolated from the screw 5, the conductive rod 22 will not connect to the electroplated layer through water or the screw 5, and therefore will not be electrically connected to the metal cup body 1 to generate a grounding signal. Consequently, the control device will not receive a false anti-overflow signal, preventing misjudgment of the anti-overflow by the control device, improving the accuracy of anti-overflow detection, ensuring smooth food processing, and preventing undercooked food.

[0053] In one embodiment of this invention, the insulating component 7 can be formed by curing the injected insulating adhesive. By injecting liquid insulating adhesive, the gap between the decorative ring 4 and the handle base 31 can be sealed in a conformal manner. Subsequently, after the insulating adhesive cures, the electroplated layer of the decorative ring 4 and the screw 5 are isolated.

[0054] Of course, in another implementation, the insulating component 7 is an insulating silicone component, which can be clamped and fixed between the decorative ring 4 and the handle seat 31 during the assembly of the decorative ring 4 and the handle seat 31. Then, during the process of fixing the decorative ring 4, the handle seat 31 and the handle cover 32 by the screws 5, the insulating silicone component is squeezed and pressed. After the installation is completed, the compression of the insulating silicone component itself can completely seal the gap between the decorative ring 4 and the handle seat 31, thereby achieving isolation between the electroplated layer of the decorative ring 4 and the screws 5.

[0055] In this embodiment, as Figure 2 , Figure 5 and Figure 6 As shown, where Figure 6 This is a schematic diagram of the decorative ring 4 described in this application embodiment. The decorative ring 4 has a mating groove 41 on the side facing the handle base 31. The mating groove 41 is connected to the electroplated layer via a step 42. The end face of the handle base 31 abuts against the insulating member 7 within the mating groove 41, and the top of the handle base 31 abuts against the step 42. Through this mating groove 41, which is connected to the electroplated layer via the step 42, the decorative ring 4 can be positioned for installation, facilitating the fixing of the handle base 31 and the decorative ring 4 with screws 5. Furthermore, the end face of the handle base 31 abuts against the insulating member 7 within the mating groove 41, allowing the insulating member 7 to be concealed within the groove, making the food processing machine more aesthetically pleasing.

[0056] More preferably, in this embodiment, the upper end of the insulating member 7 can extend to the top of the handle base 31 and be held in place by the step 42. This allows the insulating member 7 to also seal the gap between the handle base 31 and the step 42, further improving the isolation stability between the electroplated layer of the decorative ring 4 and the screw 5, ensuring that water cannot enter the gap between the decorative ring 4 and the handle base 31, or flow out from the gap between the decorative ring 4 and the handle base 31 and electrically connect to the electroplated layer of the decorative ring 4.

[0057] In this embodiment, a positioning groove 314 is provided on the side of the handle base 31 near the metal cup body 1, and a portion of the lower end of the decorative ring 4 is installed in the positioning groove 314. The positioning groove 314 makes the installation of the decorative ring 4 more convenient, and at the same time, the handle base 31 supports the decorative ring 4 through the positioning groove 314, thereby improving the installation stability of the decorative ring 4.

[0058] In this embodiment, as Figure 2 and Figure 7 As shown, a shell 8 is also fitted over the metal cup body 1. The handle seat 31 is integrally formed into the shell 8. An annular slot 81 is provided on the top of the shell 8. An annular insertion part 43 is provided at the lower end of the decorative ring 4. The annular insertion part 43 is inserted into the annular slot 81.

[0059] The decorative ring 4 is inserted into the annular slot 81 of the outer casing 8 via the annular insertion part 43 at the lower end of the decorative ring 4. This, combined with the structure in which part of the decorative ring 4 is placed in the positioning groove 314, further improves the installation stability of the decorative ring 4.

[0060] For example, such as Figure 5 As shown, in this embodiment, the handle base 31 has a mounting hole at the end facing the decorative ring 4. A waterproof plug 9 is interference-fitted into the mounting hole, and a through hole is formed in the center of the waterproof plug 9. The wire of the coupling component 6 passes through the through hole and is connected to the control device. By setting the waterproof plug 9, moisture can be prevented from entering the food processing machine along the wire of the coupling component 6, thus preventing damage to the control device.

[0061] Optionally, in this embodiment, a sandwich layer is formed between the metal cup body 1 and the outer shell 8. After the wire of the coupling component 6 passes through the waterproof plug 9, it extends along the sandwich layer to the bottom of the metal cup body 1 and is connected to the control device.

[0062] Preferably, such as Figure 7 As shown, the bottom of the handle base 31 in this embodiment is provided with a drain hole 313, through which water flowing into the mounting cavity 311 is discharged. By providing a drain hole 313 at the bottom of the handle base 31, water entering the mounting cavity 311 can be quickly discharged from the handle base 31, thereby reducing the impact of water on the conductive rod 22 and coupling component 6 in the mounting cavity 311.

[0063] In this embodiment, as Figure 8As shown, the coupling component 6 includes a first spring 61 and a second spring 62. Both the first spring 61 and the second spring 62 are electrically connected to the control device. After the cup lid 2 is installed in place, the conductive rod 22 is inserted between the first spring 61 and the second spring 62 and abuts against the first spring 61 and the second spring 62, so that the conductive rod 22 is coupled to the coupling component 6. Optionally, a plate-shaped connecting plate can be provided at the end of the conductive rod 22. When the cup lid 2 is installed in place, the connecting plate is located between the first spring 61 and the second spring 62 and is in contact with and coupled to the first spring 61 and the second spring 62.

[0064] The coupling component 6 sets up a first spring 61 and a second spring 62. When the cup lid 2 is installed in place, the connecting plate of the conductive rod 22 is simultaneously coupled with the first spring 61 and the second spring 62, enabling the control device to conduct the circuit. This is equivalent to identifying whether the cup lid 2 is installed in place. When the cup lid 2 is installed in place, the circuit is connected and the machine works normally. If the cup lid 2 is not installed in place, the connecting plate cannot couple with the first spring 61 and the second spring 62 to conduct the circuit, and the machine will not start. This achieves the identification and detection of whether the cup lid 2 is installed in place, avoiding safety problems caused by starting the food processing machine when the cup lid 2 is not installed in place, making it safer to use. Meanwhile, after the cup lid 2 is installed, the connecting plate and the coupling component 6 are coupled simultaneously through the first spring 61 and the second spring 62, which conducts the circuit between the conductive rod 22 and the control device and also realizes the identification and detection of the anti-overflow signal. When the liquid in the metal cup 1 overflows to the detection end that contacts the anti-overflow electrode 21, the conductive rod 22 feeds back the anti-overflow signal to the control device. The control device can control to stop heating or stop the motor of the food processor to prevent the slurry from overflowing. Conversely, if the liquid in the metal cup 1 does not overflow to the detection end that contacts the anti-overflow electrode 21, the conductive rod 22 will not feed back the anti-overflow signal to the control device. The control device controls the food processor to work normally, effectively preventing the slurry from overflowing while ensuring that the food is fully cooked.

[0065] It should be noted that the food processing machine in this application embodiment can be a soy milk maker, or a blender, health pot, or other household appliance products that can process liquid ingredients.

[0066] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
