Description

Technical Field

[0001] The present application relates to the technical field of small household appliances, and in particular to a blender cup assembly and a food processor. Background Art

[0002] The food processor includes a main unit and a blending cup assembly. The blending cup assembly includes a blending cup and a blending blade assembly. The main unit includes a driving device that drives the blade assembly of the blending blade assembly to rotate within the blending cup.

[0003] In order to facilitate cleaning of the mixing blade assembly, the blade assembly of the mixing blade assembly is usually set to be detachable. However, when assembling the blade assembly, the detachable blade assembly often fails to be properly assembled, which may pose a safety risk. Utility Model Content

[0004] The purpose of this application is to disclose a blending cup assembly and a food processor to avoid safety risks caused by improper assembly of the knife assembly.

[0005] In a first aspect, the present application discloses a blending cup assembly. The blending cup assembly includes a blade shaft, a blade assembly, a transmitting element, and a receiving element, wherein the blade assembly includes an assembly part and a blade, and the assembly part and the blade are arranged integrally or separately. The blade assembly is assembled to the blade shaft through the assembly part and rotates synchronously with the blade shaft. The transmitting element and the receiving element are arranged relative to each other, and a signal path is formed between the transmitting element and the receiving element. When the blade assembly is not assembled or is not correctly assembled to the blade shaft, the signal path is not blocked by the blade assembly. When the blade assembly is correctly assembled to the blade shaft, the signal path is blocked by the blade assembly.

[0006] As set up above, the assembly relationship between the knife assembly and the knife shaft is judged by whether the receiving element can receive the signal transmitted by the transmitting element. When the receiving element cannot receive the signal transmitted by the transmitting element, the knife assembly is correctly assembled to the knife shaft, which can avoid the safety risks caused by improper assembly between the knife assembly and the knife shaft, such as the safety risks caused by the knife assembly being detached from the knife shaft due to improper assembly between the knife assembly and the knife shaft.

[0007] In some embodiments, when the blade assembly is properly assembled to the blade shaft, a signal path between the transmitting element and the receiving element is blocked by the assembly.

[0008] As described above, since the knife assembly is assembled to the knife shaft through the assembly part, by detecting whether the assembly part blocks the signal path, it can be more accurately determined whether the knife assembly is assembled in place.

[0009] In some embodiments, in the axial direction of the blade shaft, the signal path is located between the top surface of the assembly and the bottom surface of the assembly; in the radial plane of the blade shaft, the signal path is located outside the circumscribed circle of the blade shaft and intersects with the circumscribed circle of the assembly.

[0010] As set up above, the signal path is outside the circumscribed circle of the knife shaft, and the signal is not blocked by the knife shaft. However, the signal path intersects with the circumscribed circle of the assembly, causing the signal to be blocked by the assembly. Thus, it is possible to more accurately judge whether the knife assembly is assembled in place, thereby avoiding the safety risks caused by improper assembly between the knife assembly and the knife shaft.

[0011] In some embodiments, in the axial direction of the blade shaft, the distance between the signal path and the top surface or the bottom surface of the assembly is h, 0<h≤5mm.

[0012] As set above, 0<h≤5mm can avoid misjudgment and make the judgment of the axial position relationship more accurate. This is because if h is larger, the receiving element is more likely to fail to receive the signal emitted by the transmitting element, and even if the knife assembly is not assembled in place, it will be judged as assembled in place, resulting in a misjudgment.

[0013] In some embodiments, when the knife assembly is properly assembled to the knife shaft, the signal path between the transmitting element and the receiving element is intermittently blocked by the blade.

[0014] As set up above, whether the knife assembly is properly assembled is determined by judging whether the blade blocks the signal, thereby avoiding the safety risks caused by improper assembly between the knife assembly and the knife shaft.

[0015] In some embodiments, the assembly includes a cutter shaft sleeve and a fixing nut, wherein the fixing nut and the cutter shaft sleeve are both passed through the cutter shaft, and the blade is clamped by the fixing nut and the cutter shaft sleeve through a threaded connection.

[0016] As described above, the blade is clamped by threading the fixing nut and the knife shaft sleeve. The assembly between the various components of the knife assembly is simple. Moreover, the knife shaft sleeve and the fixing nut have axes. This assembly method, combined with the aforementioned transmitting element and receiving element, can better ensure that the knife shaft sleeve blocks the signal path, and the judgment of whether the knife assembly is assembled in place is more accurate.

[0017] In some embodiments, the blending cup assembly includes a blending cup and a cup base, wherein the cup base is assembled with the blending cup; and the emitting element is clamped between the blending cup and the cup base.

[0018] As configured above, the emitting element is clamped between the stirring cup and the cup holder. The assembling of the emitting element is simple and firm, and the positional relationship between the emitting element and the receiving element can be ensured.

[0019] In some embodiments, the blending cup assembly includes a handle assembly, the cup base includes a handle mounting portion protruding outward from the cup base, and the emitting element is located between the handle mounting portion and the blending cup.

[0020] As described above, the emitting element is assembled using the handle mounting portion and the blending cup, which does not complicate the structure of the blending cup assembly.

[0021] In some embodiments, the blending cup assembly includes a cup base bottom cover, the cup base bottom cover is assembled with the cup base, and the receiving element is clamped between the cup base bottom cover and the cup base.

[0022] As described above, since the receiving element is clamped between the cup holder bottom cover and the cup holder, the assembly of the receiving element is simple and firm, and the positional relationship between the transmitting element and the receiving element can be ensured.

[0023] In a second aspect, embodiments of the present application disclose a food processor, comprising a main unit and any one of the aforementioned blending cup assemblies, wherein the main unit or blending cup assembly comprises a control board connected to the receiving element.

[0024] As configured above, the food processor at least has the beneficial effects of the stirring blade assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] See also Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 10and combined Figure 2 The present application discloses a blending cup assembly 10. The blending cup assembly 10 includes a blade shaft 1, a blade assembly 2, a transmitting element 3 and a receiving element 4. In addition, the blending cup assembly 10 also includes a blade disc 5, a blending cup 61, a cup seat 62, a decorative ring 63, a cup seat bottom cover 64, a waterproof sealing ring 65, a cup bottom sealing ring 66 and a handle assembly 67. The blade shaft 1 is rotatably connected to the blade disc 5. The blade assembly 2 includes an assembly 21 and a blade 22. The assembly 21 and the blade 22 are arranged integrally or separately. The blade assembly 2 is assembled to the blade shaft 1 through the assembly 21 and rotates synchronously with the blade shaft 1. Based on the function of the assembly 21, its structure is not limited. In the embodiment of the present application, the assembly 21 includes a blade shaft sleeve 211 and a fixing nut 212.

[0038] See also Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 , the transmitting element 3 and the receiving element 4 are arranged relative to each other, and the relative arrangement does not require that the transmitting element 3 and the receiving element 4 are completely opposite to each other, as long as a signal path is formed between the receiving element 4 and the transmitting element 3 so that the receiving element 4 can receive the signal emitted by the transmitting element 3. This signal can be an optical signal, an electromagnetic signal, etc. When the knife assembly 2 is not assembled or is not correctly assembled to the knife shaft 1, there are no obstacles in the signal path between the receiving element 4 and the transmitting element 3 (see as described later), the signal is not blocked by the knife assembly 2, and the receiving element 4 can receive the signal emitted by the transmitting element 3. When the knife assembly 2 is correctly assembled to the knife shaft 1, the signal path is blocked by the knife assembly 2, and thus, the receiving element 4 cannot receive the signal emitted by the transmitting element 3.

[0039] As set up above, the assembly relationship between the knife assembly 2 and the knife shaft 1 is determined by whether the receiving element 4 can receive the signal emitted by the transmitting element 3. When the receiving element 4 cannot receive the signal emitted by the transmitting element 3, the knife assembly 2 is correctly assembled to the knife shaft 1, which can avoid the safety risks caused by improper assembly between the knife assembly 2 and the knife shaft 1, for example, the safety risks caused by the knife assembly 2 being separated from the knife shaft 1 due to improper assembly between the knife assembly 2 and the knife shaft 1.

[0040] See also Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 and combined Figure 2 and Figure 3In some embodiments, when the knife assembly 2 is correctly assembled to the knife shaft 1 , the signal path between the transmitting element 3 and the receiving element 4 is blocked by the assembly 21 .

[0041] As described above, since the knife assembly 2 is assembled to the knife shaft 1 through the assembly part 21, by detecting whether the assembly part 21 blocks the signal path, it can be more accurately determined whether the knife assembly 2 is assembled in place.

[0042] See also Figure 7 and Figure 6 In the axial direction of the blade shaft 1, the signal path is higher than the bottom surface of the assembly 21, and in the figure, is higher than the bottom surface of the blade shaft sleeve 211. In other embodiments, the signal path may also be lower than the top surface of the assembly 21 (in the embodiment of the present application, lower than the top surface of the fixing nut 212). In short, in the axial direction of the blade shaft 1, the signal path is located between the top surface and the bottom surface of the assembly 21.

[0043] See also Figure 8 and Figure 9 On the radial plane of the blade shaft 1, the signal path is located outside the circumscribed circle of the blade shaft 1 and intersects with the circumscribed circle of the assembly 21. That is to say, the signal path is located outside the circumscribed circle of the blade shaft 1, and the signal is not blocked by the blade shaft 1, while the signal path intersects with the circumscribed circle of the assembly 21, causing the signal to be blocked by the assembly 21.

[0044] As set up above, the signal path is located outside the circumscribed circle of the blade shaft 1, and the signal is not blocked by the blade shaft 1. However, the signal path intersects with the circumscribed circle of the assembly 21, so that the signal is blocked by the assembly 21. Thus, it is more accurate to judge whether the blade assembly 2 is assembled in place, thereby avoiding the safety risks caused by improper assembly between the blade assembly 2 and the blade shaft 1.

[0045] See also Figure 6 and Figure 7 In the axial direction of the blade shaft 1, the distance between the signal path and the bottom surface of the assembly 21 is h, 0<h≤5mm. In other embodiments, the distance between the signal path and the top surface of the assembly 21 can also be the above h.

[0046] As set above, 0<h≤5mm can avoid misjudgment and make the judgment of the axial position relationship more accurate. This is because if h is larger, the receiving element 4 is more likely to fail to receive the signal emitted by the transmitting element 3, and even if the knife assembly 2 is not assembled in place, it will be judged as assembled in place, resulting in a misjudgment.

[0047] The aforementioned embodiment determines whether the knife assembly 2 is assembled in place by determining whether the assembly part 21 of the knife assembly 2 blocks the signal. As a variation of this embodiment, it is also possible to determine whether the knife assembly 2 is assembled in place by determining whether the blade 22 blocks the signal, thereby avoiding the safety risk caused by improper assembly between the knife assembly and the knife shaft. This embodiment is as follows: When the knife assembly 2 is correctly assembled on the knife shaft 1, the signal path between the transmitting element 3 and the receiving element 4 is intermittently blocked by the blade 22. When the blade 22 rotates with the knife shaft 1 and happens to rotate onto the signal path, the transmission of the signal is blocked, and the receiving element 4 cannot receive the signal sent by the transmitting element 3. When the blade 22 is not located on the signal path, the signal is not blocked, and the receiving element 4 can receive the signal sent by the transmitting element 3.

[0048] In light of the blocking of the above-mentioned gap, in the implementation method of detecting whether the assembly 21 blocks the signal, the knife shaft 1 can also be rotated intermittently to determine whether the assembly 21 can continue to block the signal. If so, the knife assembly 2 is still assembled in place with the knife shaft 1.

[0049] Through the aforementioned intermittent rotation, misjudgment can be avoided, and the intermittent time t can be set according to demand.

[0050] In any of the above-mentioned embodiments, if the blade assembly 2 is not assembled or not fully assembled, the receiving element 4 can receive the signal from the transmitting element 3, but if it is fully assembled, it cannot receive the signal emitted by the transmitting element 3. This can be considered as a change from the presence of a signal to the absence of a signal, and the two signals are different. Therefore, based on this inspiration, in other embodiments, the signal path being blocked by the blade assembly 2 also includes: after the signal is blocked by the blade assembly 2, the receiving element 4 can receive the signal, but the signal is different from the signal when the blade assembly 2 is not assembled or is not assembled correctly. Technicians will understand that this embodiment can also avoid the safety risks caused by improper assembly between the blade assembly 2 and the blade shaft 1.

[0051] See also Figure 10 and combined Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The assembly 21 includes a blade shaft sleeve 211 and a fixing nut 212. The fixing nut 212 and the blade shaft sleeve 211 are threaded through the blade shaft 1. After the fixing nut 212 and the blade shaft sleeve 211 are threadedly connected, the blade 22 is clamped by the fixing nut 212 and the blade shaft sleeve 211. As a result, the blade assembly 2 can rotate synchronously with the blade shaft 1.

[0052] As described above, the blade 22 is clamped by threading the fixing nut 212 and the knife shaft sleeve 211. The assembly between the various components of the knife assembly 2 is simple. Moreover, the knife shaft sleeve 211 and the fixing nut 212 both have axes. This assembly method is combined with the aforementioned transmitting element 3 and receiving element 4 to better ensure that the knife shaft sleeve 211 blocks the signal path, and the judgment of whether the knife assembly 2 is assembled in place is more accurate.

[0053] See also Figure 3 and Figure 6 and combined Figure 4 、 Figure 5 、 Figure 7 and Figure 2 The blending cup assembly 10 includes a blending cup 61 and a cup holder 62. The cup holder 62 is assembled with the blending cup 61 in any manner, such as by threading or snap-fit ​​assembly. The emitting element 3 is clamped between the blending cup 61 and the cup holder 62. There are many ways to achieve this clamping, as long as it is ultimately located between the blending cup 61 and the cup holder 62. In the embodiment of the present application, the blending cup assembly 10 also includes a decorative ring 63. The blending cup 61, the cup holder 62, and the decorative ring 63 collectively clamp the emitting element 3.

[0054] As described above, the emitting element 3 is clamped between the stirring cup 61 and the cup holder 62 . The assembling of the emitting element 3 is simple and firm, and the positional relationship between the emitting element 3 and the receiving element 4 can be ensured.

[0055] In some embodiments, the blending cup assembly 10 includes a cup base cover 64, the cup base cover 64 is assembled with the cup base 62, and the receiving element 4 is clamped between the cup base cover 64 and the cup base 62. Figure 3 、 Figure 4 as well as Figure 6 、 Figure 5 and Figure 7 It is only shown that the receiving element 4 is pressed against the top of the cup holder 62 . However, those skilled in the art will appreciate that a corresponding structure may be provided on the cup holder bottom cover 64 to press against the bottom of the receiving element 4 or against the side of the receiving element 4 . Ultimately, the receiving element 4 is clamped between the cup holder bottom cover 64 and the cup holder 62 .

[0056] As described above, since the receiving element 4 is clamped between the cup holder bottom cover 64 and the cup holder 62 , the assembly of the receiving element 4 is simple and firm, and the positional relationship between the transmitting element 3 and the receiving element 4 can be ensured.

[0057] For ease of assembly, the emitting element 3 or receiving element 4 can be provided with a groove 31 or protrusion 32 on either the top or bottom of the receiving element 4, and a corresponding protrusion 32 or groove 31 on the cup holder 62 or cup holder bottom cover 64. The concave-convex fit of the groove 31 and protrusion 32 allows the receiving element 4 to be positioned, facilitating assembly. Similarly, the emitting element 3 can be provided with a groove 31 or protrusion 32 on either the top or bottom of the emitting element 3, and a corresponding groove 31 or protrusion 32 on the cup holder 62 or decorative ring 63. The concave-convex fit of the groove 31 and protrusion 32 allows the receiving element 4 to be positioned, facilitating assembly.

[0058] See also Figure 2 and combined Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8 The blending cup assembly includes a handle assembly 67. The cup holder 62 includes a handle mounting portion 621 protruding outward from the cup holder 62. The emitting element 3 is located between the handle mounting portion 621 and the blending cup 61.

[0059] As described above, the emitting element 3 is assembled using the handle mounting portion 621 and the blending cup 61 , which does not complicate the structure of the blending cup assembly 10 .

[0060] In some embodiments, the blending cup assembly includes a control board (marked in the figure), and the control board is connected to the receiving element 4 in any manner, for example, the connection is achieved through a coupler.

[0061] In other embodiments, the control panel may be provided on the host. Figure 1 The present application further provides a food processor, which includes a main unit 20 and any one of the aforementioned blending cup assemblies 10 , wherein the main unit 20 includes a control panel connected to the receiving element 4 .

[0062] As configured above, the food processor at least has the beneficial effects of the blending cup assembly, which will not be described in detail.

[0063] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
