In the present embodiment, the annular body 10, the detecting portion 30 and a protruding rib 51 are all made of metal material, and the three are in an integrated structure. The annular body 10, the detecting portion 30, and the protruding rib 51 are allowed to be made of stainless steel, and the three are allowed to be produced and processed by stamping. Certainly, the three are further allowed to be produced by die casting or welding. In case the overflow prevention ring 100 is mounted in a food processor 500, the annular body 10 is embedded in the peripheral edge of a cup opening or a feeding port of a blending cup assembly of the food processor 500, the detecting portion 30 extends into a cavity of the blending cup, and the lead connecting structure 50 is connected with a conductor configured to transmit signals. In the process of stirring food materials by the food processor, in case the food materials in the blending cup assembly touches the detecting portion 30 of the overflow prevention ring 100, the voltage of the detecting portion 30 is changed, thus generates a control signal transmitted to the main control board through the conductor connected with the lead connecting structure 50, and then the main control board sends an instruction, and the food processor stops stirring the food materials. It should be understood that the food processor mounted with the overflow prevention ring 100 further has an overflow prevention function in the process of heating the food materials. In the process of heating the food materials, in case foam generated in the blending cup assembly touches the detecting portion 30, the main control board of the food processor receives an overflow signal, and controls the heating device to stop heating according to the overflow signal to prevent the food materials in the blending cup assembly from overflowing.
In the present disclosure, the overflow prevention ring 100 is configured as the lead connecting structure 50 connected to the outer edge of the annular body 10, and a detecting portion 30 is connected to the inner edge of the annular body 10. The annular body 10, the detecting portion 30, and the lead connecting structure 50 are in electrically conduction. By configuring the overflow prevention ring 100 in an annular shape, the overflow prevention ring 100 is relatively easily to be mounted at the cup opening or the feeding port of the blending cup assembly. Meanwhile, the present disclosure further configures the outer diameter of the annular body 10 is at least 50 mm, and at most 80 mm, which ensures that the overflow prevention ring 100 is firm mounted on the blending cup assembly and allows the overflow prevention ring 100 and the blending cup assembly of the food processor being better combined together, while the opening size of the overflow prevention ring 100 may also be allowed to be reasonably configured to feed the food materials into the blending cup assembly during the operation of the food processor. In case the outer diameter of the annular body 10 of the overflow prevention ring is less than 50 mm, the opening diameter of the overflow prevention ring 100 is too small to facilitate feeding in the operation of the food processor. In case the outer diameter of the annular body 10 of the overflow prevention ring 100 is larger than 80 mm and the overflow prevention ring 100 has a suitable mounting area, the opening diameter of the overflow prevention ring 100 is too large, so that the food materials are not easily to contact with the overflow prevention ring 100 in the operation of the food processer, so that the detection accuracy of the food processor is reduced. The outer diameter of the annular body 10 of the overflow prevention ring 100 of the present disclosure is configured to be at least 50 mm, and at most 80 mm, so that the overflow prevention ring has a better detection width. In the process of stirring food of the food processor, the detecting portion 30 configured at the inner edge of the annular body 10 is allowed to accurately detect whether the food materials rush to the cup opening or the feeding port of the blending cup assembly during the stirring process, so that the overflow prevention ring 100 of the present disclosure is allowed to accurately detect whether the food materials overflow during the stirring process of the food processor.
In one embodiment, the outer diameter of the annular body 10 of the present embodiment is at least 65 mm, and at most 75 mm. In one embodiment, the outer diameter of the annular body 10 of the present embodiment is 74 mm. With this value, the optimal detection effect of the overflow prevention ring 100 is achieved.
Further, on the basis the annular body 10 having an outer diameter being at least 65 mm, and at most 75 mm, an inner diameter of the annular body 10 is at least 55 mm, and at most 65 mm. In addition, in case the outer diameter of the annular body 10 is 74 mm, the inner diameter of the annular body 10 can be 64 mm. Within this numerical range, the optimal detection effect of the overflow prevention ring 100 is achieved.
Further, on the basis the annular body 10 having the above-mentioned outer diameter range, a horizontal projection area of the annular body 10 of the present disclosure is at least 1300 mm2, and at most 2000 mm2.
In the present disclosure, the horizontal projection area of the annular body 10 is further configured to be at least 1300 mm2, and at most 2000 mm2. Within this numerical range of the area, the annular body 10 and the blending cup assembly have a more appropriate contact area, making the connection between the annular body 10 and the blending cup assembly be much more firm, no matter the annular body 10 is connected with the blending cup assembly by gluing or embedding. During use, even though the food processor shakes, the overflow prevention ring 100 can still be tight enough with the blending cup assembly. The overflow prevention ring and the blending cup assembly of the food processor in the present disclosure are allowed to be better combined together.
In case the horizontal projection area of the annular body is less than 1300 mm2, namely the combined area of the overflow prevention ring 100 and the blending cup assembly is small, the connection between the two would be affected. While, in case the horizontal projection area of the annular body is greater than 2000 mm2, then the blending cup assembly needs reserving much more mounting space for the overflow prevention ring, which is not beneficial to the structural design of the blending cup assembly, and may also reduce the structural strength of the blending cup assembly. Further, the material cost of the overflow prevention ring 100 would be increased.
In the present disclosure, the horizontal projection area of the annular body 10 is configured to be at least 1300 mm2, and at most 2000 mm2, so that providing the overflow prevention ring 100 an appropriate detection area. In the food stirring process of the food processor, the detecting portion 30 configured at the inner edge of the annular body 10 is allowed to accurately detect whether the food materials rush to the cup opening or the feeding port of the blending cup assembly. So, the overflow prevention ring 100 of the present disclosure can accurately detect whether the food materials overflow during the food stirring process.
Further, the horizontal projection area of the annular body 10 of the present embodiment is at least 1400 mm2, and at most 1800 mm2. With this value, the optimal detection effect of the overflow prevention ring 100 is achieved.
The detecting portion 30 of the overflow prevention ring 100 of the present disclosure is allowed to have various structures, and an angle formed between the side wall of the detecting portion 30 and the annular body 10 is at least 60 degrees, and at most 120 degrees.

In the present disclosure, the lead connecting structure 50 includes a protruding rib 51 connected to the outer edge of the annular body 10, and an end of the protruding rib 51 away from the annular body 10 defines a lead fixing structure. The plane of the protruding rib 51 located coincides with the plane of the annular body 10 located. In the present disclosure, an assembly space is reserved for the connection between the conductor configured to transmit signals and the overflow prevention ring 100 through the configuration of the protruding rib 51 of the overflow prevention ring 100, so that the overflow prevention ring 100 can be easily mounted. Meanwhile, the protruding rib 51 and the annular body 10 are arranged on the same plane, so that the overflow prevention ring 100 is allowed to be embedded in the side wall of a cup body of the blending cup assembly more easily, the overflow prevention ring 100 is not prone to be touched and loosen, and the appearance of the blending cup assembly may also be attractive after the mounting of the overflow prevention ring 100. In one embodiment of the present disclosure, the lead fixing structure is a threading hole 53 defined at the protruding rib 51. During mounting of the overflow prevention ring 100, lead first passes through the threading hole 53 and then conductor is welded to get a firm connection.

The cup lid assembly of the present embodiment further includes an upper lid 206 in cover connection with the lower lid 204, and the upper cover 206 partially extends into the feeding port 2042. The blending cup assembly 200 further includes a stirring blade assembly (not shown) partially extending into the blending cup 202. During the food processor 500 in use, the stirring blade assembly rotates at a high speed under the drive of the motor of the host to stir the food materials in the blending cup 202. The food materials in the blending cup 202 is allowed to be added through the cup opening of the blending cup 202 before the food processor being started and the cup lid assembly covers the blending cup 202. If the food materials need to be added continuously in the process of the food processor stirring the food materials, the upper lid 206 is allowed to be opened, and the food materials can be continuously added through the feeding port 2042. The overflow prevention ring 100 is mounted on the lower lid 204 and located at the peripheral edge of the feeding port 2042.
In the present disclosure, the overflow prevention ring 100 is defined at the peripheral edge of the feeding port 2042 of the lower lid 204 of the cup lid assembly, in case the food materials in the blending cup 202 rush to the feeding port 2042 in the process of stirring the food materials by the food processor, overflow signals are generated as long as the food materials touch the overflow prevention ring 100, according to which the food processor is allowed to make corresponding actions to prevent the food materials in the blending cup assembly 200 from overflowing. The process of assembling the overflow prevention ring 100 to the lower lid 204 is relatively simple by defining the overflow prevention ring 100 at the peripheral edge of the feeding port 2042 of the lower lid 204 without additionally arranging a structure inside the cup lid assembly for mounting the overflow prevention ring 100. Further, the overflow prevention ring 100 is allowed to accurately detect whether the food materials rush to the cup opening or the feeding port 2042 of the blending cup assembly 200 during the stirring process, thus an accurate detection is achieved.
Further, the lower lid 204 concavely defines a mounting slot 2044 in communication with the feeding port 2042 at the peripheral edge of the feeding port 2042, and the overflow prevention ring 100 is at least partially embedded in the mounting slot 2044. The overflow prevention ring 100 is convenient to be assembled and disassembled by defining the mounting slot 2044 in the lower lid 204 for the overflow prevention ring 100 being embedded in, and an additional mounting structure would no longer be needed to be arranged inside the cup lid assembly for the overflow prevention ring 100 to be mounted.

The detecting portion 30 extends to one side of the blending cup 202 by a distance being at least 1 mm, and at most 25 mm. According to this arrangement, the food materials are easily to touch the detecting portion 30 in case the food materials rush to the feeding port 2042, thus the detection for overflow prevention of the blending cup assembly 200 of the present disclosure is more sensitive and accurate.
In the present embodiment, the wall thickness of the annular body 10 is at least 0.5 mm, and at most 3 mm, and the depth of the mounting slot 2044 matches the wall thickness of the annular body 10. The connection between the overflow prevention ring 100 and the lower lid 204 in the present embodiment is allowed to be realized by gluing. The annular body 10 is flush with the surface of the lower lid 204 having the feeding port 2042 after the annular body 10 being embedded in the mounting slot 2044, thus the overflow prevention ring 100 will not protrude from the lower lid 204. During the food processor in use, the overflow prevention ring 100 can still be tight with the lower lid 204 even scraping happens, and the overall structure may also be attractive.
The detecting portion 30 of the overflow prevention ring 100 of the present disclosure is allowed to have various structural, and the detecting portion 30 is a barrel fixedly connected to the inner edge of the annular body 10. The barrel of the present embodiment is allowed to be a straight barrel structure with the side wall of the barrel being configured at right angles to the annular body 10. The detecting portion 30 is configured as a barrel, which allows the food materials rushing to the cup opening or the feeding port 2042 being easily contacted by the detecting portion 30 to generate overflow signals, thus the detection for overflow is more sensitive. It should be understood that, the detecting portion 30 is a barrel structure, the inner diameter of the barrel is allowed to be gradually enlarged or reduced from one end close to the annular body 10 to the other end away from the annular body 10, making the detecting portion 30 be an open or necked shape. Thus, during the overflow prevention ring performing overflow prevention detection and the detecting portion 30 conducting electric detection via the voltage change, the side wall of the detecting portion 30 can also assist to prevent the food materials from overflow, namely, to reduce the overflow of the food materials in the blending cup assembly at the cup opening or the feeding port.
Further, the ratio of the outer diameter of the lower lid 204 to the outer diameter of the annular body 10 is at least 1.1, and at most 3.5.
In the present disclosure, the overflow prevention ring 100 is configured as the annular body 10, and the detecting portion 30 is connected to the inner edge of the annular body 10. The overflow prevention ring 100 is easily to be mounted at the feeding port 2042 of the lower lid 204 by configuring the overflow prevention ring 100 in an annular shape.
Meanwhile, in the present disclosure, the ratio of the outer diameter of the lower lid 204 to the outer diameter of the annular body is configured to be at least 1.1, and at most 3.5. Thus with the general outer diameter size of the existing blending cup assembly, the opening size of the feeding port 2042 defined in the lower lid 204 and matched with the overflow prevention ring 100 is allowed to be reasonably configured, which is beneficial to feed the food materials into the blending cup assembly during the food processor in use, so the overflow prevention ring 100 and the blending cup assembly 200 of the food processor are allowed to be better combined together.
In the present disclosure, the ratio of the outer diameter of the lower lid 204 and the outer diameter of the annular body 10 is configured to be at least 1.1, and at most 3.5, so that providing the overflow prevention ring 100 an appropriate detection range. In the process of stirring food by the food processor, the detecting portion 30 configured at the inner edge of the annular body 10 is allowed to accurately detect whether the food materials rush to the cup opening or the feeding port of the blending cup assembly. Thus the overflow prevention ring 100 of the present disclosure is allowed to accurately detect whether the food materials overflow in the process of stirring the food materials by the food processor.
In case the ratio of the outer diameter of the lower lid 204 to the outer diameter of the annular body 10 is smaller than 1.1, then the opening diameter of the feeding port 2042 of the blending cup assembly 200 will be too large. During the operation of the food processor 500, the food materials may come out of the blending cup assembly from the middle part of the feeding port, making the food materials be not easily to contact the overflow prevention ring 100, thus reduces the detection accuracy of the food processor 500. In case the ratio of the outer diameter of the lower lid 204 to the outer diameter of the annular body 10 is larger than 3.5, then the opening diameter of the feeding port 2042 of the blending cup assembly is too small to facilitate feeding during the food processor 500 in use.
Further, the diameter of the lower lid 204 is at least 90 mm, and at most 180 mm. The outer diameter of the annular body 10 is at least 55 mm, and at most 80 mm. The diameter of the lower lid 204 is at least 130 mm, and at most 160 mm, and 150 mm is in one embodiment. The outer diameter of the annular body 10 is at least 60 mm, and at most 80 mm, and 74 mm is in one embodiment. Thus, the blending cup assembly 200 has better functional status, better feeding and detection effects.
Further, the inner diameter of the annular body 10 is at least 50 mm, and at most 70 mm. The inner diameter of the annular body 10 can be further reduced to be at least 55 mm, and at most 65 mm. In case the outer diameter of the annular body 10 is 74 mm, the inner diameter of the annular body 10 is 64 mm. Within this numerical range, the optimal detection effect of the overflow prevention ring 100 is achieved.
Further, on the basis the annular body 10 having the above-mentioned outer diameter range, the horizontal projection area of the annular body 10 of the present disclosure is at least 1300 mm2, and at most 2000 mm2.
In the present disclosure, the horizontal projection area of the annular body 10 is further configured to be at least 1300 mm2, and at most 2000 mm2. Within this numerical range of the area, the annular body 10 and the blending cup assembly have a more appropriate contact area, making the connection between the annular body 10 and the blending cup assembly be much more firm, no matter the annular body 10 is connected with the blending cup assembly by gluing or embedding. During use, even though the food processor shakes, the overflow prevention ring 100 can still be tight enough with the blending cup assembly. The overflow prevention ring and the blending cup assembly 200 of the food processor 500 are allowed to be better combined together.
