Description

Technical Field

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

[0002] Existing blenders typically include a base, a cup body mounted on the base, and a lid that fits onto the cup body. A motor is located at the center of the base to drive the pulverizing blades at the bottom of the cup body. Additionally, an anti-overflow detection device is installed on the cup body or lid, and a microswitch is also located on the cup body. Both the anti-overflow detection device and the microswitch need to be connected to a circuit board within the base; therefore, a coupler is used between the cup body and the base to achieve this connection (as shown in prior art CN201821344678.1). However, because the motor is located at the center of the base, the overall height of the base is relatively large, resulting in a high position for the cup body mounted on the base. This causes the cup body to shake and generate significant noise during blender operation.

[0003] The prior art CN202120727856.4 discloses a three-section food processing machine for making soy milk, including a machine head, a cup body, and a base assembly. The base assembly has a receiving cavity, and a lower coupler is provided in the receiving cavity. The bottom of the cup body is provided with an upper coupler that cooperates with the lower coupler to transmit electricity. The upper coupler is installed on the bottom cover of the cup body and spans the heating tube. The base assembly is provided with a lower coupler opposite to the upper coupler. The cup body is positioned on the base assembly by the insertion and cooperation of the upper and lower couplers.

[0004] In this structure, because the upper coupler needs to span the heating element, and to prevent the heat from the heating element from damaging or melting the upper coupler, a sufficiently large vertical distance needs to be set between the heating element and the upper coupler. This results in a relatively high cup height, making the center of gravity of the entire cup high. When the food processor is running, the vibration of the motor will cause the cup to wobble relative to the base assembly. Since the upper coupler spans the heating element, and the cup is positioned relative to the base assembly via the upper and lower couplers, the cup will wobble with the upper and lower couplers as the fulcrum. Furthermore, the side of the cup furthest from the upper and lower couplers will wobble more, resulting in significant collision noise between the cup body and the base assembly. Moreover, because the cup's center of gravity is high, there is also a risk of the cup tipping over, affecting the user experience. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, this application provides a soymilk maker that effectively solves the safety risks of existing soymilk makers where the upper coupler is set across the heating element, causing the cup to shake easily due to vibration during operation, resulting in significant collision noise with the base, and even tipping over.

[0006] This application provides a soymilk maker, including a base, a cup body mounted on the base, and a head fastened to the cup body. The base contains a circuit board and a first lower coupler electrically connected to the circuit board. The cup body includes a cup body base, and an annular heating element is provided on the outer surface of the bottom wall of the cup body base. A first upper coupler with a non-circular outline is provided in the central region inside the heating element. The first upper coupler is electrically connected to the heating element and fixed to the bottom wall of the cup body base. The cup body and the base are connected and engaged by the first upper coupler and the first lower coupler.

[0007] This application utilizes a non-circular first upper coupler located in the central region inside the heating element. Firstly, by placing the first upper coupler in the central region inside the heating element, it eliminates the need for it to span the heating element, thus reducing the vertical distance between the heating element and the coupler. This lowers the overall height of the cup and shifts its center of gravity downwards, improving the stability of the cup during operation, reducing the amplitude of wobbling caused by vibration, and minimizing collision noise between the cup and the base. Secondly, the central location of the first upper coupler allows the cup to connect to the base via the insertion of the first upper and lower couplers in the central region. This provides support for the central region of the cup during operation, effectively reducing unilateral wobbling, lowering noise, reducing the risk of tipping, and improving the user experience.

[0008] As a preferred technical solution, the cup body includes a through glass cup, a heating plate installed at the bottom of the glass cup, a mounting bracket fixedly connected to the glass cup and supporting the heating plate, and a bottom cover fixed to the mounting bracket. The heating tube is installed on the heating plate, the first upper coupler is fixed on the heating plate, and the open end of the first upper coupler cooperates with the through hole on the bottom cover.

[0009] By mounting both the heating element and the first upper coupler on the heating plate, with the first upper coupler located in the central area of ​​the heating element, the overall height of the cup is reduced, improving the stability of the cup during operation and reducing the amplitude of the cup shaking due to vibration.

[0010] As a preferred technical solution, the glass cup includes a handle, the top of the handle is provided with a second lower coupler, and the side wall of the mounting bracket extends axially with two spaced stiffeners. The wire of the second lower coupler is clamped between the two stiffeners and connected to the first upper coupler.

[0011] As a preferred technical solution, the base is provided with a receiving groove to accommodate the cup body, and the first lower coupler is disposed in the central area of ​​the receiving groove.

[0012] By setting a receiving groove to accommodate the cup, the cup's periphery can be restricted by the receiving groove, thereby reducing the cup's swaying amplitude. In addition, the first lower coupler is located in the central area of ​​the receiving groove, ensuring that the central area of ​​the cup is effectively supported by the plug-in cooperation of the first upper coupler and the first lower coupler.

[0013] As a preferred technical solution, the bottom wall of the receiving groove is provided with a positioning protrusion surrounding the first lower coupler, and the cup body is provided with a positioning groove, with the positioning protrusion embedded in the positioning groove.

[0014] By embedding the positioning protrusion into the positioning groove, the cup body can be further restricted by the base to prevent shaking. At the same time, the positioning protrusion is arranged around the first lower coupler, which can also increase the stable support of the base for the cup body in the circumferential direction.

[0015] As a preferred technical solution, a shock-absorbing pad is provided between the receiving groove and the cup body.

[0016] As a preferred technical solution, the top end face of the first upper coupler is higher than the lowest point of the heating tube in the vertical direction.

[0017] By making the top end face of the first upper coupler higher than the lowest point of the heating tube in the vertical direction, the top of the first upper coupler is located within the space formed by the heating tube, which can effectively reduce the height of the bottom of the cup, thereby lowering the height of the cup's center of gravity, reducing the cup's swaying amplitude, and reducing the collision noise caused by the cup's swaying.

[0018] As a preferred technical solution, the outer side of the cup body is provided with a detection plate for detecting the liquid level in the air. The first upper coupler is provided with a first pin and a second pin. The first pin is connected to the heating tube, and the second pin is connected to the detection plate.

[0019] As a preferred technical solution, the circuit board includes a control board for the operating interface and a power board connected to the first lower coupler. The control board and the power board are isolated by an insulating board, and the electrical components on the control board are arranged opposite to the electrical components on the power board.

[0020] As a preferred technical solution, the cup body includes a handle, the top wall of the handle is provided with a mounting hole, and a second lower coupler is installed on the top wall of the handle. The second lower coupler includes a body, the body is provided with an insertion part, and the outer peripheral wall of the body is provided with a flange located above the insertion part. The flange is located on the top wall of the handle. The insertion part is inserted into the mounting hole, and the outer peripheral wall of the insertion part is provided with a slot. A snap-fit ​​component is snapped into the slot so that the snap-fit ​​component and the flange clamp the top wall of the handle. Attached Figure Description

[0035] 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.

[0036] 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.

[0037] In existing technology, a three-section soymilk maker including a machine head, a cup body, and a base assembly has an upper coupler installed on the bottom cover of the cup body and spanning the heating element. To prevent the heat from the heating element from damaging or melting the upper coupler, a sufficiently large vertical distance needs to be set between the heating element and the upper coupler. This results in a relatively high cup body, making the center of gravity of the entire cup body high. When the food processor is running, the vibration of the motor causes the cup body to shake relative to the base assembly. Since the upper coupler spans the heating element, and the cup body is positioned relative to the base assembly via the upper and lower couplers, the cup body will shake with the upper and lower couplers as the fulcrum. Furthermore, the side of the cup body away from the upper and lower couplers will shake more, resulting in significant collision noise between the body and the base assembly.

[0038] Based on the above-mentioned technical problems, this application provides a soymilk maker, such as... Figure 1 The diagram shows the structure of a soymilk maker. The soymilk maker includes a base 1, a cup body 2, and a machine head 3. The cup body 2 can be placed inside the base 1, and the machine head 3 is fastened inside the cup body 2. The end of the machine head 3 is equipped with a grinding blade that is driven to rotate by a motor. The grinding blade can grind and process the ingredients inside the cup body 2.

[0039] Figure 2 This is an exploded structural diagram of the cup body 2 provided in the embodiments of this application. Figure 3This is a cross-sectional view of the cup body 2 provided in an embodiment of this application. Figure 4 This is a schematic diagram showing the bottom structure of the cup body 2, provided for an embodiment of this application. (See attached diagram.) Figure 2 and Figure 3 As shown, the cup body 2 in this embodiment includes a cup body base. An annular heating element 21 is provided on the outer surface of the bottom wall of the cup body base. The cup body base also includes a glass cup 22, a heating plate 23, a mounting bracket 24, and a bottom cover 25. The glass cup 22 has a through-type cylindrical structure. The heating plate 23 is installed at the bottom of the glass cup 22, and the heating element 21 is installed on the heating plate 23. The mounting bracket 24 is fixedly connected to the bottom of the glass cup 22 and supports the heating plate 23. The bottom cover 25 is fixedly installed on the mounting bracket 24. Through the above structure, the cup body base as a whole forms a cup body 2 that can hold food, and the food inside the glass cup 22 can be heated by the heating element 21 on the heating plate 23.

[0040] In this embodiment, reference can be made to Figure 3 and Figure 4 A first upper coupler 26 is installed on the heating plate 23. Specifically, the first upper coupler 26 is located in the central region inside the heating tube 21, and the first upper coupler 26 is electrically connected to the heating tube 21. Correspondingly, Figure 5 This is a three-dimensional structural diagram of the base 1 provided in the embodiments of this application, as shown below. Figure 5 As shown, a receiving groove 11 is provided on the base 1, which is used to receive the cup body 2. A first lower coupler 12 is installed in the central area of ​​the receiving groove 11. The first lower coupler 12 can be plugged into and cooperate with the first upper coupler 26 to realize the electrical connection between the two.

[0041] In this embodiment, by setting the first upper coupler 26 in the central area inside the heating tube 21, the first upper coupler 26 does not need to be set across the heating tube 21, and therefore does not need to set a large vertical distance between the heating tube 21 and the first upper coupler 26. This reduces the overall height of the cup body 2, lowers the center of gravity of the cup body 2, improves the stability of the cup body 2 when the soy milk maker is running, reduces the amplitude of the cup body 2 shaking due to vibration, and reduces the collision noise between the cup body 2 and the base 1.

[0042] In addition, by setting the first lower coupler 12 in the central area of ​​the receiving slot 11, the cup body 2 and the base 1 are connected in the central area through the insertion of the first upper coupler 26 and the first lower coupler 12. This ensures that the central area of ​​the cup body 2 has stable support during the operation of the soy milk maker, effectively reducing the swaying amplitude of the cup body 2 on one side, reducing the safety risk of the cup body 2 tipping over, reducing noise, and improving the user experience.

[0043] Moreover, compared to the prior art where the first upper coupler is fixedly installed on the bottom cover of the cup body, and the heating tube is electrically connected to the first upper coupler via a wire, there is a risk of wire pinching when the bottom cover is assembled onto the mounting bracket. In this embodiment, the first upper coupler 26 is fixedly installed below the heating plate 23. When the bottom cover 25 is installed, there is no risk of wire pinching between the heating tube 21 and the first upper coupler 26.

[0044] Furthermore, preferably, in this embodiment, the top end face of the first upper coupler 26 is higher than the lowest point of the heating tube 21 in the vertical direction. That is, by ensuring the top end face of the first upper coupler 26 is higher than the lowest point of the heating tube 21 in the vertical direction, the top of the first upper coupler 26 is located within the space enclosed by the heating tube 21, effectively reducing the height of the bottom of the cup body 2, thereby lowering the center of gravity of the cup body 2, reducing the swaying amplitude of the cup body 2, and reducing the collision noise caused by the swaying of the cup body 2. Of course, it is understood that the top end face of the first upper coupler 26 could also be flush with the lowest point of the heating tube 21 in the vertical direction, or the top end face of the first upper coupler 26 could be separated from the lowest point of the heating tube 21 by a small preset distance in the vertical direction, which would also satisfy the requirement of lowering the center of gravity of the cup body 2.

[0045] It should be noted that in this embodiment, the cup body 2 is accommodated in the receiving groove 11 of the base 1, which enables the cup body 2 to be restricted by the receiving groove 11, thereby reducing the shaking amplitude of the cup body 2. In addition, the first lower coupler 12 is located in the central area of ​​the receiving groove 11, ensuring that the central area of ​​the cup body 2 is effectively supported by the plug-in cooperation of the first upper coupler 26 and the first lower coupler 12.

[0046] In this embodiment, the outlines of the first upper coupler 26 and the first lower coupler 12 are both non-circular, such as... Figure 4 and Figure 5 As shown, the outlines of the first upper coupler 26 and the first lower coupler 12 are both elongated oval outlines (also known as racetrack-shaped outlines), and both are 8-pin couplers. It is understood that the outlines of the first upper coupler 26 and the first lower coupler 12 can also be other shapes, and they can also be 5-pin or other pin count couplers.

[0047] For example, in this embodiment, a through hole 251 is provided on the bottom cover 25. Figure 2 As shown, the open end of the first upper coupler 26 engages with the through hole 251 provided on the bottom cover 25. Specifically, the open end of the first upper coupler 26 can be flush with the through hole 251 or can pass through a part of the through hole 251, thereby enabling it to be plugged into the first lower coupler 12.

[0048] Continue to refer to Figure 4 and Figure 5 A positioning groove 252 is provided at the bottom of the bottom cover 25, and a positioning protrusion 13 surrounding the first lower coupler 12 is provided on the bottom wall of the receiving groove 11. When the cup body 2 is placed in the receiving groove 11, the positioning protrusion 13 is embedded in the positioning groove 252, so that the cup body 2 can be further restricted by the base 1 to prevent shaking. At the same time, the positioning protrusion 13 is arranged around the first lower coupler 12, which can also increase the stability support of the base 1 for the cup body 2 in the circumferential direction, and further reduce the shaking amplitude of the cup body 2.

[0049] Preferably, in this embodiment, a shock-absorbing pad is provided between the receiving groove 11 and the cup body 2 to reduce the vibration of the cup body 2 during the operation of the soymilk maker. Furthermore, in order to facilitate the installation of the shock-absorbing pad and make reasonable use of space, the shock-absorbing pad is attached to the positioning protrusion 13.

[0050] Figure 6 This is a structural diagram of the cup body 2 with the bottom cover 25 hidden in an embodiment of this application, as shown below. Figure 6 As shown, in this embodiment, two positioning posts 231 extend downward from the bottom of the heating plate 23. Positioning portions 261 extend outward from both side walls of the first upper coupler 26. Screws pass through the positioning portions 261 and are threaded onto the positioning posts 231 to fix the positioning portions 261 and the positioning posts 231. This structure ensures that the first upper coupler 26 is stably fixed to the heating plate 23, thereby preventing positional displacement of the first upper coupler 26 and avoiding interference with the insertion and engagement with the first lower coupler 12.

[0051] Figure 7 This is a cross-sectional view of the base 1 provided in an embodiment of this application. Figure 7 As shown, a circuit board is installed inside the base 1. This circuit board includes a control board 14 and a power board 16, and an insulating plate 15 is provided between the control board 14 and the power board 16. The insulating plate 15 isolates the control board 14 and the power board 16, meaning that the control board 14, the insulating plate 15, and the power board 16 are arranged sequentially from top to bottom. Furthermore, in this embodiment, the electrical components on the control board 14 and the electrical components on the power board 16 are arranged opposite to each other.

[0052] A knob 17 is provided on one side of the base 1 located in the receiving groove 11. The control board 14 is electrically connected to the knob 17 so that the function control of the soy milk maker (such as gear control, temperature control and time control) can be realized by operating the knob 17. Alternatively, a control panel can be provided on the base 1, and the control board 14 can be electrically connected to the control panel to realize the function control of the soy milk maker.

[0053] It should be noted that the power board 16 is electrically connected to the first lower coupler 12, and thus the power board 16 and the heating element 21 are electrically connected through the electrical connection between the first upper coupler 26 and the first lower coupler 12, and the electrical connection between the heating element 21 and the first upper coupler 26. Optionally, as... Figure 8 As shown, Figure 8 The diagram shows an exploded view of the cup body 2 with a detection plate 27 in this embodiment. The outer wall of the glass cup 22 in this embodiment is also provided with a detection plate 27. This detection plate 27 can detect the liquid level inside the glass cup 22 remotely, thereby achieving liquid level detection. The detection plate 27 is electrically connected to a first upper coupler 26. Exemplarily, the first upper coupler 26 may have a first pin and a second pin. The first pin is connected to the heating element 21, and the second pin is connected to the detection plate 27. At this time, through the insertion and engagement of the first upper coupler 26 and the first lower coupler 12, and the electrical connection between the first lower coupler 12 and the power board 16, the power board 16 is electrically connected to the heating element 21 and the detection plate 27. This allows the power board 16 to control the heating element 21 and collect the detection signal from the detection plate 27.

[0054] In this embodiment, a handle 28 is also provided on the outside of the glass 22. The top of the handle 28 is fastened to the top of the glass 22, and the bottom is fixedly connected to the mounting bracket 24. Optionally, as... Figure 2 and Figure 3 As shown, a mounting hole 281 is provided on the top wall of the handle 28. A second lower coupler 29 is inserted into the mounting hole 281. The second lower coupler 29 is electrically connected to the first upper coupler 26 via a wire. Correspondingly, a second upper coupler (not shown in the figure) is provided on the machine head 3. The motor and detection components (such as temperature sensors) inside the machine head 3 are electrically connected to the second upper coupler. The second lower coupler 29 is plugged into the second upper coupler to achieve electrical connection. Through the electrical connection of the second upper coupler and the second lower coupler 29, the electrical connection of the second lower coupler 29 to the first upper coupler 26, and the electrical connection of the first lower coupler 12 to the power board 16, the motor and detection components inside the machine head 3 can be connected to the power board 16. The power board 16 controls the operation of the motor and receives the detection signals from the detection components.

[0055] Preferably, in this embodiment, as Figure 9 As shown, Figure 9 Examples of this application Figure 2An enlarged schematic diagram at point A. The second lower coupler 29 includes a body with an insertion portion at its lower end. A flange 291 is located above the insertion portion on the outer peripheral wall of the body. The insertion portion is inserted into the mounting hole 281. The flange 291 is located on the top wall of the handle 28. A slot 292 is provided on the outer peripheral wall of the insertion portion. A snap-fit ​​member 2a is also provided inside the handle 28, snapping into the slot 292, so that the snap-fit ​​member 2a and the flange 291 clamp the top wall of the handle 28. Through this structure, the second lower coupler 29 is completely fixed to the top wall of the handle 28. Preferably, the slot 292 can be a U-shaped slot surrounding the outer peripheral wall of the insertion portion, and correspondingly, the snap-fit ​​member 2a can be… Figure 9 The U-shaped connector shown, through its cooperation with the U-shaped slot, makes the installation and fixation of the second lower coupler 29 more secure.

[0056] For reference Figure 4 In this embodiment, a handle chamber is provided inside the handle 28. The handle chamber contains a first wire-locking groove 282 and a second wire-locking groove 283. The first wire-locking groove 282 is used to secure the high-voltage wire in the conductor connected to the second lower coupler 29 (this high-voltage wire is connected to the motor via the second lower coupler 29 and the second upper coupler). The second wire-locking groove 283 is used to secure the low-voltage wire in the conductor connected to the second lower coupler 29 (this low-voltage wire is connected to the detection component via the second lower coupler 29 and the second upper coupler). The first wire-locking groove 282 and the second wire-locking groove 283 allow for the separation of the high-voltage and low-voltage wires, facilitating subsequent maintenance. Preferably, multiple first wire-locking grooves 282 and second wire-locking grooves 283 are spaced apart along the extension direction of the handle chamber, so that the high-voltage and low-voltage wires can be completely fixed within the handle chamber to prevent wire movement.

[0057] Adaptively, such as Figure 10 As shown, Figure 10 This is a schematic diagram of the mounting bracket 24 according to an embodiment of this application. Two spaced stiffeners 241 are provided on the side wall of the mounting bracket 24 along its axial direction. The wire of the second lower coupler 29 passes through the first wire clamping groove 282 and the second wire clamping groove 283, is clamped between the two stiffeners 241, and is finally connected to the first upper coupler 26.
