Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a soy milk maker. Background Technology

[0002] Existing soymilk makers have an anti-overflow electrode in the lid. This electrode has a detection end and a conductive connection end. The detection end extends into the inner cavity of the lid, and the conductive connection end is connected to a metal rod for outputting an anti-overflow signal to the control device. The anti-overflow detection principle is as follows: Since the heating cup of a soymilk maker is generally made of stainless steel and grounded, when the soymilk inside boils and rises to the point of almost overflowing, it contacts the detection end of the anti-overflow electrode, causing the electrode to connect to ground and generate a grounding signal, i.e., an anti-overflow signal. This signal is then transmitted to the control device to identify the anti-overflow status.

[0003] In the development of the soymilk maker, the applicant employs the following installation method for the anti-overflow component: A cup lid with a corresponding protrusion above the handle is fixed to the lower lid, forming an installation cavity. The lower lid fills the height difference between the upper end of the handle and the cup body, allowing the cup lid to fit stably onto the cup body. Simultaneously, a conductive connection end protrudes into the installation cavity, thus concealing the conductive connection end of the anti-overflow electrode. This conductive connection end is also connected to a metal connecting rod, one end of which extends from the installation cavity. A coupling component for connection to the control device is provided on the cup body handle. When the cup lid and cup body are fastened together, the metal connecting rod couples with the coupling component to transmit signals to the control device.

[0004] However, the separate connection between the lower lid and the cup lid's protrusion inevitably creates gaps in the fit. Water may enter the mounting cavity during cleaning or during processing, causing condensation. When water is present inside the mounting cavity, it comes into contact with the metal connecting rod and conductive connection. Due to its conductivity, water will conduct through the gap between the lower lid and the cup body's protrusion, generating a grounding signal that is transmitted to the control device. The control device, upon receiving this grounding signal, interprets it as an anti-overflow signal, even when the liquid level inside the cup has not actually risen to the point of overflowing. This results in a false anti-overflow signal. During processing, if a false anti-overflow signal occurs, the heating element may stop prematurely, resulting in undercooked soy milk. Utility Model Content

[0005] This utility model provides a soymilk maker that solves the technical problem of undercooked soymilk caused by water entering the mounting cavity, which results in a false anti-overflow signal from the anti-overflow electrode. This is achieved by using the installation cavity to achieve a concealed installation of the conductive connection end of the anti-overflow electrode.

[0006] The technical solution adopted in this utility model is as follows:

[0007] This utility model provides a soymilk maker, including a metal cup body, a handle disposed on one side of the metal cup body, and a cup lid mounted on the metal cup body. The cup lid is provided with an anti-overflow electrode. The handle is provided with a coupling component electrically connected to a control device. The cup lid is also provided with a metal connecting rod. The anti-overflow electrode is coupled to the coupling component through the metal connecting rod to transmit an anti-overflow signal to the control device. The anti-overflow electrode includes a detection end and a connection end. The detection end extends into the metal cup body. The cup lid has a cup lid protrusion and a mounting cover fixedly connected to the cup lid protrusion from the edge towards the handle side. The mounting cover is aligned and fitted with the top of the handle. The mounting cover and the cup lid protrusion form a mounting cavity. The connection end extends into the mounting cavity. The metal connecting rod is installed below the mounting cover and electrically connected to the connection end. An insulating sleeve is also provided in the mounting cavity and sleeved on the outer periphery of the connection end. The insulating sleeve isolates the connection end from the mounting cavity.

[0008] The soymilk maker provided by this utility model utilizes the enclosure formed between the mounting cover and the cup lid protrusion to create a mounting cavity. The connecting end extends into the mounting cavity, achieving a concealed design of the connecting end. This avoids unstable signal transmission and inaccurate overflow detection caused by exposed connections, thus improving detection reliability. By installing the metal connecting rod below the mounting cover and electrically connecting it to the connecting end, and with an insulating sleeve fitted around the connecting end within the mounting cavity, the connecting end is isolated from the mounting cavity. Therefore, the insulating sleeve provides insulation protection for the connecting end, preventing water from entering the mounting cavity and causing water to conduct through the metal cup and connecting end, resulting in a false overflow signal. This ensures accurate overflow detection and avoids undercooked soymilk due to misjudgment.

[0009] In a preferred embodiment, the insulating sleeve is a sealing ring that is held and fixed by the cup lid protrusion and the mounting cover.

[0010] By setting the insulating sleeve as a sealing ring, which is clamped and fixed by the cup lid protrusion and the mounting cover, the sealing ring utilizes its own flexible deformation characteristics to form a tight seal with the connecting end while sealing and isolating the connecting end from the mounting cavity. This further prevents water from entering the mounting cavity and causing the overflow electrode to conduct, thus improving detection accuracy. At the same time, the sealing ring can also absorb assembly errors caused by the processing errors of the cup lid protrusion and the mounting cover, ensuring a tight fit between the cup lid protrusion and the mounting cover and preventing water from entering the mounting cavity.

[0011] More preferably, the mounting cover has a boss protruding toward the connecting end, the cup lid protrusion has a surrounding rib extending toward the boss and wrapping around the connecting end, and the sealing ring is clamped between the boss and the surrounding rib.

[0012] By incorporating a boss on the mounting cover, the boss, facing the connection end, raises the water storage height below the connection end. This prevents water accumulation above the boss even in the presence of a small amount of water in the mounting cavity, reducing the probability of water contacting the insulating sleeve and connection end. The sealing ring is reliably secured using the reinforcing ribs and the boss, achieving effective insulation protection for the connection end.

[0013] In a preferred embodiment, the insulating sleeve is integrally formed on the cup lid protrusion and extends toward the mounting cover, the mounting cover having a through hole for the insulating sleeve to extend out of the mounting cavity.

[0014] By integrally molding the insulating sleeve onto the protruding part of the cup lid, separate assembly is eliminated, simplifying the assembly process. A perforation is provided in the mounting cover, allowing the insulating sleeve to extend out of the mounting cavity. The gap between the insulating sleeve and the perforation can also be used to allow water to seep out of the mounting cavity, preventing water accumulation in the mounting cavity.

[0015] In a preferred embodiment, the insulating sleeve is a sealing sleeve integrally formed on the mounting cover, and the cup cover protrusion is provided with an annular groove surrounding the outer periphery of the connecting end, and the sealing sleeve is interference-fitted into the annular groove.

[0016] By integrally molding the insulating sleeve into the mounting cover, the assembly steps can still be simplified. An annular groove is set on the protrusion of the cup cover, surrounding the outer periphery of the connection end. The sealing sleeve is inserted into the annular groove with an interference fit, so that the sealing sleeve and the annular groove are sealed together. At the same time, the water inlet path is extended, which further increases the difficulty for water in the mounting cavity to enter the inner side of the insulating sleeve and come into contact with the connection end, thereby improving the insulation protection effect of the connection end and effectively preventing the water in the mounting cavity from conducting electricity with the connection end.

[0017] In a preferred embodiment, the connecting end is a stud with internal threads, the metal connecting rod is located at the lower end of the mounting cover, and the screw passes through the metal connecting rod and the mounting cover to fix the metal connecting rod to the stud.

[0018] By setting the connecting end as a stud with internal threads, and using screws to fix the metal connecting rod to the stud, the metal connecting rod is fixed while also achieving a reliable electrical connection with the connecting end, thus achieving structural integration.

[0019] In a preferred embodiment, the mounting cover has an extension extending toward the side wall of the handle, the side wall of the extension having a positioning groove for positioning the metal connecting rod, the side wall of the handle having a mating hole, the coupling member being disposed within the mating hole, and the cup cover being rotated so that the metal connecting rod passes through the mating hole and is electrically coupled to the coupling member.

[0020] By setting an extension in the mounting cover and using a positioning groove on the side wall of the extension, reliable positioning of the metal connecting rod is achieved, preventing the metal connecting rod from shifting or loosening due to frequent disassembly and assembly of the cup cover by the user. This ensures a reliable electrical connection between the metal connecting rod and the coupling component. By placing the coupling component inside the mating hole, the metal connecting rod passes through the mating hole and couples with the coupling component by rotating the cup cover. This also avoids opening a hole above the coupling component, thus preventing the coupling component from being damaged by water, and ensuring a durable and effective fit between the metal connecting rod and the coupling component.

[0021] In a preferred embodiment, a positioning groove is provided on the lower end face of the mounting cover, and the top end of the metal connecting rod is fixed in the positioning groove.

[0022] By setting a positioning groove, the top of the metal connecting rod is reliably limited and fixed with the positioning groove, preventing the metal connecting rod from falling off or shifting from the mounting cover, thereby improving the reliable electrical connection between the metal connecting rod and the coupling component. By fixing the top of the metal connecting rod, the bottom of the metal connecting rod can be exposed, so that when the cup cover is vertically closed and fixed with the cup body, the metal connecting rod and the coupling component can be plugged in and engaged.

[0023] In a preferred embodiment, the coupling component includes a first spring and a second spring, both of which are electrically connected to the control device. A connecting plate is provided at the end of the metal connecting rod. After the cup lid is installed in place, the first spring and the second spring are located on both sides of the connecting plate and abut against the connecting plate to achieve electrical coupling between the metal connecting rod and the coupling component.

[0024] By setting a first and a second spring in the coupling component, when the cup lid is installed in place, the first and second springs are located on both sides of the connecting plate and abut against the connecting plate, realizing simultaneous coupling between the connecting plate and the first and second springs. This enables the control device to conduct the circuit, which is equivalent to identifying whether the cup lid is installed in place. When the cup lid is installed in place, the circuit is connected and the machine works normally. If the cup lid is not installed in place, the connecting plate cannot couple with the first and second springs to conduct the circuit, and the machine will not start. This realizes the identification and detection of whether the cup lid is installed in place, avoiding the safety problem of starting the motor when the cup lid is not installed in place, making it safer to use. Meanwhile, after the cup lid is installed, the connecting plate and the coupling component are coupled simultaneously through the first and second springs, conducting the circuit between the metal connecting rod and the control device. It also realizes the identification and detection of the anti-overflow signal. When the liquid in the metal cup overflows to the detection end that contacts the anti-overflow electrode, the metal connecting rod feeds back a low-frequency signal to the control device. The control device can then control the heating to stop or stop the motor to prevent the soy milk from overflowing. Conversely, if the liquid in the metal cup does not overflow to the detection end that contacts the anti-overflow electrode, the metal connecting rod feeds back a high-frequency signal to the control device. The control device then controls the motor and heating tube to work normally, effectively preventing the soy milk from overflowing while ensuring that it is fully cooked.

[0025] In a preferred embodiment, the cup lid has a main unit cavity for accommodating the control device, a motor is provided in the main unit cavity, the motor shaft extends out of the main unit cavity and is connected to a pulverizing blade, and the pulverizing blade extends into the metal cup body;

[0026] In a preferred embodiment, the soymilk maker includes a housing fitted over the outside of the metal cup body, a main unit cavity formed between the housing and the metal cup body located below the metal cup body, a control device located in the main unit cavity, a motor also provided in the main unit cavity, and a grinding blade driven by the motor provided inside the metal cup body.

[0027] By incorporating the main unit cavity into the cup lid and housing the control device within it, a machine head-type soymilk maker is created, simplifying the structure and weight of the metal cup body and making it easier for users to clean.

[0028] By setting up an outer shell, the main unit cavity is formed by the outer shell and the metal cup, which houses the control device and the motor, forming a soymilk maker with the motor located at the bottom. This lowers the center of gravity of the whole machine and makes it more stable in operation.

[0029] Of course, whether it is a machine head type soy milk maker or a bottom-mounted motor type soy milk maker, because an insulating sleeve is set inside the installation cavity and placed around the outer periphery of the connecting end, the insulating sleeve isolates the connecting end from the installation cavity, thereby ensuring accurate anti-overflow detection and avoiding the situation where the soy milk is not cooked properly due to misjudgment.

[0041] Many specific details are set forth in the following description to provide a full understanding of the present invention.

[0045] like Figure 1-7As shown, in one embodiment, this utility model provides a soymilk maker, including a metal cup body 10, a handle 70 disposed on one side of the metal cup body 10, and a cup lid 20 mounted on the metal cup body 10. The cup lid 20 is provided with an anti-overflow electrode 40. The handle 70 contains a coupling component 30 electrically connected to a control device. The cup lid 20 also has a metal connecting rod 60. The anti-overflow electrode 40 is coupled to the coupling component 30 via the metal connecting rod 60 to transmit an anti-overflow signal to the control device 13 of the soymilk maker. Figure 2 As shown, the anti-overflow electrode 40 includes a detection end 41 and a connection end 42. The detection end 41 extends into the metal cup body 10. The cup lid 20 has a cup lid protrusion 21 protruding from the edge towards the handle 70, and a mounting cover 22 fixedly connected to the cup lid protrusion 21. The mounting cover 22 is aligned and fitted with the top of the handle 70. The mounting cover 22 and the cup lid protrusion 21 form a mounting cavity 23. The connection end 42 extends into the mounting cavity 23. The metal connecting rod 60 is installed below the mounting cover 22 and electrically connected to the connection end 42. Figure 2 , 3 As shown, the mounting cavity 23 is also provided with an insulating sleeve 50 that is sleeved on the outer periphery of the connecting end 42, and the insulating sleeve 50 isolates the connecting end 42 from the mounting cavity 23.

[0046] like Figure 4 As shown, in this utility model, the detection end 41 and the connection end 42 of the anti-overflow electrode 40 are connected by a conductive element 43, which is a lead wire or a metal rod. The anti-overflow electrode 40 is injection molded in the cup lid 20.

[0047] The soymilk maker provided by this utility model utilizes the enclosure formed by the mounting cover 22 and the cup lid protrusion 21 to create a mounting cavity 23. The connecting end 42 extends into the mounting cavity 23, achieving a concealed setting for the connecting end 42. This avoids unstable signal transmission and inaccurate anti-overflow detection caused by exposure, thus improving detection reliability. By installing the metal connecting rod 60 below the mounting cover 22 and electrically connecting it to the connecting end 42, the mounting cavity 23 is also provided with an insulating sleeve 50 that is fitted around the connecting end 42. The insulating sleeve 50 isolates the connecting end 42 from the mounting cavity 23. Therefore, the insulating sleeve 50 provides insulation protection for the connecting end 42, preventing water from entering the mounting cavity 23 and causing water to conduct through the metal cup body 10 and the connecting end 42, resulting in a false anti-overflow signal. This ensures accurate anti-overflow detection and avoids situations where the soymilk is not fully cooked due to misjudgment.

[0048] It should be noted that this utility model does not limit the form of the soymilk maker, for example... Figure 1-7As shown, in a preferred embodiment, the soymilk maker is a bottom-mounted motor type. The soymilk maker includes a housing 11 fitted over the outside of a metal cup 10. A main unit cavity is formed between the housing 11 and the metal cup 10, located below the metal cup 10. A control device is located within the main unit cavity, and a motor 80 is also housed therein. A grinding blade 90 driven by the motor 80 is located inside the metal cup 10. By setting up the housing 11, the main unit cavity is formed by the housing 11 and the metal cup 10, accommodating the control device and the motor 80, thus creating a bottom-mounted motor type soymilk maker. This lowers the center of gravity of the entire machine, resulting in more stable operation.

[0049] Of course, in another preferred embodiment of this invention, the soymilk maker is a head-type soymilk maker. Specifically, the cup lid 20 has a main unit cavity for accommodating the control device. A motor 80 is housed within the main unit cavity, and the shaft of the motor 80 extends out of the main unit cavity and connects to a grinding blade 90, which extends into the metal cup body 10. By providing a main unit cavity in the cup lid 20 and housing the control device within it, a head-type soymilk maker is formed, simplifying the structure and weight of the metal cup body 10 and making it easier for users to clean.

[0050] Understandably, whether it is a machine head type soymilk maker or a motor 80 bottom-mounted soymilk maker, because an insulating sleeve 50 is set inside the installation cavity 23 and sleeved around the outer periphery of the connecting end 42, the insulating sleeve 50 isolates the connecting end 42 from the installation cavity 23, thereby ensuring accurate anti-overflow detection and avoiding the situation where the soymilk is not cooked properly due to misjudgment.

[0051] This utility model does not limit the specific structure and installation of the insulating sleeve 50. In a preferred embodiment, such as... Figure 1-7 As shown, the insulating sleeve 50 is a sealing ring that is clamped and fixed by the cup lid protrusion 21 and the mounting cover 22. Figure 2 As shown, more preferably, the mounting cover 22 is provided with a boss 221 protruding toward the connecting end 42, and the cup lid protrusion 21 is provided with a surrounding rib 211 extending toward the boss 221 and wrapping around the connecting end 42, and the sealing ring is clamped between the boss 221 and the surrounding rib 211.

[0052] By setting the insulating sleeve 50 as a sealing ring, which is clamped and fixed by the cup lid protrusion 21 and the mounting cover 22, the sealing ring utilizes its own flexible deformation characteristics to form a tight wrap and seal with the connecting end 42, while sealing and isolating the connecting end 42 from the mounting cavity 23. This further prevents water from entering the mounting cavity 23 and causing the overflow electrode 40 to conduct, thus improving the detection accuracy. At the same time, the sealing ring can also absorb the assembly errors caused by the processing errors of the cup lid protrusion 21 and the mounting cover 22, so that the cup lid protrusion 21 and the mounting cover 22 fit tightly, preventing water from entering the mounting cavity 23.

[0053] By providing a boss 221 on the mounting cover 22, the boss 221 faces the connecting end 42, thus raising the water storage height below the connecting end 42. Even with a small amount of water in the mounting cavity 23, water is less likely to accumulate above the boss 221, reducing the probability of water contacting the insulating sleeve 50 and the connecting end 42. The sealing ring is reliably fixed by the surrounding rib 211 and the boss 221, achieving effective insulation protection for the connecting end 42.

[0054] In other embodiments, the insulating sleeve 50 is integrally formed on the cup lid protrusion 21 and extends toward the mounting cover 22, which has a through hole for the insulating sleeve 50 to extend out of the mounting cavity 23.

[0055] By integrally molding the insulating sleeve 50 onto the cup lid protrusion 21, separate assembly is eliminated, simplifying the assembly steps. A perforation is provided in the mounting cover 22, allowing the insulating sleeve 50 to extend out of the mounting cavity 23. The gap between the insulating sleeve 50 and the perforation can also be used to allow water to seep out of the mounting cavity 23, preventing water accumulation in the mounting cavity 23.

[0056] In other embodiments, the insulating sleeve 50 is a sealing sleeve integrally formed on the mounting cover 22, and the cup cover protrusion 21 is provided with an annular groove surrounding the outer periphery of the connecting end 42, and the sealing sleeve is interference-fitted into the annular groove.

[0057] By integrally molding the insulating sleeve 50 onto the mounting cover 22, the assembly steps can still be simplified. An annular groove is provided on the cup cover protrusion 21, surrounding the outer periphery of the connecting end 42. The sealing sleeve is inserted into the annular groove with an interference fit, so that the sealing sleeve and the annular groove are sealed together. At the same time, the water inlet path is extended, further increasing the difficulty for water in the mounting cavity 23 to enter the inner side of the insulating sleeve 50 and contact the connecting end 42, thereby improving the insulation protection effect of the connecting end 42 and effectively preventing the water in the mounting cavity 23 from conducting electricity with the connecting end 42.

[0058] In another preferred embodiment, the connecting end 42 is a stud with internal threads, the metal connecting rod 60 is located at the lower end of the mounting cover 22, and the screw 24 passes through the metal connecting rod 60 and the mounting cover 22 to fix the metal connecting rod 60 to the stud.

[0059] By setting the connecting end 42 as a stud with internal threads, the metal connecting rod 60 is fixed to the stud using screw 24, thus achieving both the fixation of the metal connecting rod 60 and a reliable electrical connection with the connecting end 42, resulting in structural integration.

[0060] It is understood that, optionally, the metal connecting rod 60 and the mounting cover 22 can be fixed together to the stud by screws 24. Of course, the mounting cover 22 and the cup lid protrusion 21 can also be fixed by a snap-fit.

[0061] This utility model does not limit the specific coupling method between the metal connecting rod and the coupling component. For example, in a preferred embodiment, such as... Figure 3As shown, the mounting cover 22 has an extension 222 extending toward the side wall of the handle 70. The side wall of the extension 222 is provided with a positioning groove 223 for positioning the metal connecting rod 60. Figure 5 , 6 As shown, the side wall of the handle 70 is provided with a mating hole, and the coupling component 30 is disposed in the mating hole. The cup cover 20 is rotated so that the metal connecting rod 60 passes through the mating hole and is electrically coupled to the coupling component 30.

[0062] More specifically, such as Figure 7 As shown, the coupling component 30 includes a first spring 31 and a second spring 32, both of which are electrically connected to the control device. A connecting plate 61 is provided at the end of the metal connecting rod 60. After the cup lid 20 is installed, the first spring 31 and the second spring 32 are located on both sides of the connecting plate 61, and the connecting plate 61 is simultaneously coupled to the first spring 31 and the second spring 32. Optionally, the mounting cover 22 has a fastening portion that engages with the cup lid protrusion 21, and the positioning groove 223 extends to the lower end face of the fastening portion. The top end of the metal connecting rod 60 is fixed in the positioning groove 223.

[0063] By providing an extension 222 to the mounting cover 22 and a positioning groove 223 on the side wall of the extension 222, the metal connecting rod 60 is reliably positioned, preventing the metal connecting rod 60 from shifting or loosening due to frequent disassembly and assembly of the cup cover 20 by the user. This ensures a reliable electrical connection between the metal connecting rod 60 and the coupling component 30. By placing the coupling component 30 in the mating hole, the metal connecting rod 60 passes through the mating hole and couples with the coupling component 30 by rotating the cup cover 20. This also avoids opening a hole above the coupling component 30, thus preventing the coupling component 30 from being damaged by water. This ensures a durable and effective fit between the metal connecting rod 60 and the coupling component 30.

[0064] By setting the first spring 31 and the second spring 32 in the coupling component 30, when the cup lid 20 is installed in place, the connecting plate 61 of the metal connecting rod 60 is coupled with the first spring 31 and the second spring 32 simultaneously, so that the control device can realize circuit conduction. This is equivalent to identifying whether the cup lid 20 is installed in place. When the cup lid 20 is installed in place, the circuit conduction enables the machine to work normally. If the cup lid 20 is not installed in place, the connecting plate 61 cannot couple with the first spring 31 and the second spring 32 to conduct the circuit, and the machine will not start. This realizes the identification and detection of whether the cup lid 20 is installed in place, avoiding the safety problem of starting the motor 80 when the cup lid 20 is not installed in place, making it safer to use. Meanwhile, after the cup lid 20 is installed, the connecting plate 61 and the coupling component 30 are coupled simultaneously through the first spring 31 and the second spring 32, which conducts the circuit between the metal connecting rod 60 and the control device and also realizes the identification and detection of the anti-overflow signal. When the liquid in the metal cup 10 overflows to the detection end 41 of the anti-overflow electrode 40, the metal connecting rod 60 feeds back a low-frequency signal to the control device. The control device can control to stop heating or stop the motor 80 from working to prevent the soy milk from overflowing. Conversely, if the liquid in the metal cup 10 does not overflow to the detection end 41 of the anti-overflow electrode 40, the metal connecting rod 60 feeds back a high-frequency signal to the control device. The control device controls the motor 80 and the heating tube 12 to work normally, effectively preventing the soy milk from overflowing while ensuring that the soy milk is fully cooked.

[0065] It is understood that the structure of the above-mentioned coupling component is still applicable to other embodiments of this utility model.

[0066] In another preferred embodiment of this invention, the mounting cover 22 has a fastening part that engages with the cup lid protrusion 21, and a positioning groove 223 is provided on the lower end surface of the fastening part.
