Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of food processors, in particular to a cup cover assembly and a food processor. BACKGROUND
[0002] The food processor has a food material processing cavity. Food material is heated and whipped in the food material processing cavity. When the food material is rapidly heated, a large amount of foam is generated. At the same time, the pressure in the food material processing cavity is relatively high, and the foam rises and has a risk of overflowing. CONTENT OF THE UTILITY MODEL
[0003] The present application provides a cup cover assembly and a food processor, which can reduce the risk of foam overflow.
[0004] In a first aspect, the present application provides a cup cover assembly, comprising a main cover and an additional cover, the additional cover is assembled to the main cover; the additional cover and the main cover enclose a spill-proof cavity, the main cover has an inlet hole and an outlet hole, the inlet hole and the outlet hole are both used to communicate the spill-proof cavity and a food material processing cavity of a food processor, the additional cover has an exhaust hole, the exhaust hole communicates with the spill-proof cavity; wherein the additional cover comprises a foam blocking part, the foam blocking part is located on the inner side of the inlet hole, and the projection area of the foam blocking part on the main cover covers at least part of the area of the inlet hole in the axial direction of the inlet hole.
[0005] By adopting the above scheme, when the foam enters the spill-proof cavity through the inlet hole, at least part of the foam will hit the foam blocking part which has a lower temperature. Under the temperature change and the reaction force of the foam blocking part, the foam can be broken into more slurry and gas. The slurry can remain in the spill-proof cavity and flow back to the food material processing cavity when the pressure in the food material processing cavity decreases. The gas can flow out through the exhaust hole to reduce the pressure in the spill-proof cavity, so as to avoid the overflow of the slurry caused by the excessive pressure in the spill-proof cavity.
[0006] Optionally, in the axial direction of the inlet hole, the projection area of the foam blocking part on the main cover covers the entire area of the inlet hole.
[0007] Optionally, the main cover further comprises a downwardly recessed recess, and the additional cover further comprises an upwardly extending protrusion, the recess and the protrusion cooperate to form the spill-proof cavity.
[0008] This can ensure that as much foam as possible entering the spill-proof cavity through the inlet hole will directly hit the foam blocking part, improve the proportion of the foam being broken into slurry and gas, and more effectively reduce the amount of foam.
[0009] Optionally, the outlet hole is located at the lowest part of the recess. After the foam is broken into slurry in the spill-proof cavity, the slurry will naturally flow to the lowest part of the recess based on the principle of gravity. At this time, the outlet hole is arranged at this position, so that the slurry can most conveniently flow back to the food material processing cavity through the outlet hole.
[0010] Optionally, the main cover further comprises a side part connecting the recess, the side part is above the recess, and the inlet hole is in the side part.
[0011] In this way, the inlet hole is in the side part, and the outlet hole is in the lowest part of the recess. The inlet hole and the outlet hole are in different positions, and the height of the inlet hole is higher than that of the outlet hole. After the foam enters the anti-overflowing cavity through the inlet hole, it will not directly accumulate near the outlet hole, reducing the possibility of blocking the outlet hole.
[0012] Optionally, the foam blocking part comprises an inclined blocking surface facing the inlet hole, and the extension direction of the inclined blocking surface is towards the outlet hole.
[0013] The inclined blocking surface can change the direction of the foam entering the anti-overflowing cavity, so that the foam flows along the extension direction of the inclined blocking surface to the outlet hole, facilitating the discharge of the slurry from the outlet hole.
[0014] Optionally, an exhaust passage is further formed between the additional cover and the main cover, the exhaust passage communicates the anti-overflowing cavity and the exhaust hole, and the exhaust passage has at least one bend.
[0015] In this way, when the gas entraining the foam enters the exhaust passage, it will change direction due to inertia and continue to advance when encountering the bend. However, the foam will be blocked by the bend and will break into slurry and gas, thereby achieving further separation of gas and liquid and reducing the amount of slurry carried in the exhaust gas.
[0016] Optionally, an exhaust cavity is further formed between the additional cover and the main cover, and the exhaust cavity communicates the exhaust passage and the exhaust hole.
[0017] The exhaust cavity can serve as a place to collect residual slurry. For those slurry that cannot be completely collected in the exhaust passage, they will be intercepted when flowing into the exhaust cavity with the gas, thereby preventing the slurry in the exhaust passage from flowing out with the gas.
[0018] Optionally, the additional cover comprises a rotating and clamping joint, the main cover comprises a rotating and clamping seat, and the rotating and clamping joint is rotatably clamped into the rotating and clamping seat.
[0019] The rotating and clamping joint has a certain positioning function. When the rotating and clamping joint is screwed into the rotating and clamping seat, it will be matched according to a specific rotation track and angle, so that the additional cover and the main cover can be accurately installed in place. In this way, not only the stability of the connection between the two is ensured, but also the position and shape of the anti-overflowing cavity and other related structures (such as the exhaust passage) formed between them meet the design requirements, which is conducive to the coordinated function of the components and avoids abnormal functions caused by assembly errors.
[0020] Optionally, the radial dimension of the inlet hole is greater than the radial dimension of the outlet hole; and / or, the number of the inlet holes is multiple, and the number of the inlet holes is greater than the number of the outlet holes. This can make the foam enter from the inlet hole as much as possible, so as to impact on the foam blocking part.
[0021] In a second aspect, the application provides a food processor, comprising:
[0022] a main machine; and a cup assembly assembled to the main machine, comprising a blending cup and the cup cover assembly according to any one of the above, the blending cup having a food material processing cavity, and the main cover being fastened to a cup mouth of the blending cup.

Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0031] This application provides a cup lid assembly and a food processor, which will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.
[0032] Please refer to Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural schematic diagram of a food processor as shown in one embodiment; Figure 2 This is a cross-sectional view of a food processor as shown in one embodiment.
[0033] This application provides a food processor, including a main unit 60 and a cup assembly, the cup assembly being assembled to the main unit 60. The main unit 60 can be a base-type main unit 60, but is not limited thereto.
[0034] The cup assembly includes a mixing cup 40, a blade assembly 50, and a lid assembly. The mixing cup 40 is detachably mounted to the main unit 60 and has a food processing chamber 41 within which food can be heated and blended. Figure 1 and Figure 2 As shown, the mixing cup 40 also includes a handle 42, which is fixed to the outer wall of the mixing cup 40 for easy handling by the user. The blade assembly 50 is installed in the mixing cup 40 and located within the food processing space to blend and cut the food.
[0035] Please refer to Figure 3 and Figure 4 , Figure 3 This is an exploded structural view of a cup lid assembly as shown in one embodiment; Figure 4 This is a cross-sectional view of a cup lid assembly according to one embodiment. Figure 4 The arrow shown indicates the direction of the foam.
[0036] The cup lid assembly includes a main lid 10 and an auxiliary lid 20. The main lid 10 is fastened to the mouth of the mixing cup 40 to seal the mouth of the mixing cup 40. The auxiliary lid 20 is assembled to the main lid 10, and the assembly method includes, but is not limited to, snap-fit and threaded connection.
[0037] The additional cover 20 and the main cover 10 form an anti-overflow chamber 31 therebetween. The main cover 10 has an inlet hole 11 and an outlet hole 12, both of which are used to communicate the anti-overflow chamber 31 with a food material processing chamber 41 of the food processor. The foam in the food material processing chamber 41 can flow into the anti-overflow chamber 31 through the inlet hole 11 and flow out of the anti-overflow chamber 31 through the outlet hole 12. Of course, in the case that the food material in the food material processing chamber 41 is heated at a high power, the pressure in the food material processing chamber 41 is relatively high, and the foam in the food material processing chamber 41 can flow into the anti-overflow chamber 31 through both the inlet hole 11 and the outlet hole 12. After the pressure in the food material processing chamber 41 is reduced, the foam remaining in the anti-overflow chamber 31 can flow out of the outlet hole 12.
[0038] The additional cover 20 has a plurality of exhaust holes 22, which are in communication with the anti-overflow chamber 31 and used to exhaust the high-pressure gas in the anti-overflow chamber 31. The additional cover 20 includes a foam blocking portion 21, which is located at the inner side of the inlet hole 11. In the axial direction of the inlet hole 11, the projection area of the foam blocking portion 21 on the main cover 10 covers at least part of the area of the inlet hole 11. Here, the "inner side" refers to the side of the inlet hole 11 close to the anti-overflow chamber 31. In the axial direction of the inlet hole 11 (the Y direction shown in the reference Figure 4 In the axial direction of the inlet hole 11, the projection area of the foam blocking portion 21 on the main cover 10 covers at least part of the area of the inlet hole 11. This means that when an observer observes the inlet hole 11 and the foam blocking portion 21 along the axial direction of the inlet hole 11, the foam blocking portion 21 covers part of the area of the inlet hole 11, and the foam blocking portion 21 partially overlaps the inlet hole 11.
[0039] By using the above scheme, when the foam enters the anti-overflow chamber 31 through the inlet hole 11, at least part of the foam will hit the foam blocking portion 21, which has a relatively low temperature. Under the action of the temperature change and the reaction force of the foam blocking portion 21, the foam can be broken into a relatively slurry and gas. The slurry can remain in the anti-overflow chamber 31 and flow back to the food material processing chamber 41 after the pressure in the food material processing chamber 41 is reduced. The gas can flow out through the exhaust holes 22 to reduce the pressure in the anti-overflow chamber 31 and prevent the slurry from overflowing due to the excessively high pressure in the anti-overflow chamber 31.
[0040] In one embodiment, in the axial direction of the inlet hole 11 (the Y direction shown in the reference Figure 4 In the axial direction of the inlet hole 11, the projection area of the foam blocking portion 21 on the main cover 10 covers the entire area of the inlet hole 11. This can ensure that as much foam as possible entering the anti-overflow chamber 31 through the inlet hole 11 will directly hit the foam blocking portion 21, thereby increasing the proportion of the foam broken into slurry and gas and more effectively reducing the amount of foam.
[0041] Further, the radial dimension of the inlet hole 11 is greater than the radial dimension of the outlet hole 12, so that as much foam as possible enters from the inlet hole 11 and hits the foam blocking portion 21.
[0042] Furthermore, there are multiple inlet holes 11, and the number of inlet holes 11 is greater than the number of outlet holes 12. This also allows as much foam as possible to enter through the inlet holes 11. For example, the number of inlet holes 11 may be, but is not limited to, 2, 3, 4, 5, or 6, and the number of outlet holes 12 may be, but is not limited to, 1.
[0043] In one embodiment, the main lid 10 includes a recess 13 extending downwards, and the auxiliary lid 20 includes a protrusion 23 connected to the foam-blocking portion 21 and extending upwards. The protrusion 23 and the recess 13 cooperate to form an overflow-proof cavity 31. The cooperation between the recess 13 of the main lid 10 and the protrusion 23 of the auxiliary lid 20 cleverly utilizes the internal space of the lid assembly, efficiently constructing the overflow-proof cavity 31 without adding complex structures, making the overall structure of the blender more compact. Simultaneously, as the recess 13 is recessed downwards, the protrusion 23 protrudes upwards, increasing the capacity of the overflow-proof cavity 31, allowing it to accommodate larger amounts of foam and liquid, further reducing the risk of spillage.
[0044] Furthermore, the outlet 12 is located at the lowest point of the recess 13. Here, "lowest point" refers to the lowest point of the gravitational potential energy of the recess 13. At this point, the slurry flows out more easily due to gravity. In other words, compared to other points in the recess 13, the outlet 12 is at the lowest point in the height direction. When the foam breaks up in the overflow chamber 31 to form slurry, based on the principle of gravity, the slurry will naturally flow to the lowest point of the recess 13. The outlet 12 is positioned here to allow the slurry to flow back to the food processing chamber 41 most conveniently through the outlet 12.
[0045] Furthermore, the main cover 10 also includes a side portion 14 connected to the recess 13, the side portion 14 being located above the recess 13, and the inlet hole 11 being located on the side portion 14.
[0046] With this configuration, the inlet 11 is located on the side 14, and the outlet 12 is located at the lowest point of the recess 13. The inlet 11 and the outlet 12 are in different positions, and the height of the inlet 11 is higher than that of the outlet 12. After the foam enters the overflow prevention chamber 31 from the inlet 11, it will not accumulate directly near the outlet 12, reducing the possibility of clogging the outlet 12.
[0047] In one embodiment, the foam-blocking part 21 includes an inclined baffle 211 facing the inlet 11, with the inclined baffle 211 extending toward the outlet 12. The inclined baffle 211 can change the direction in which foam enters the anti-overflow cavity 31, causing the foam to flow toward the outlet 12 along the direction of the inclined baffle 211, facilitating the discharge of slurry from the outlet 12.
[0048] like Figure 4 In the embodiment shown, the inlet hole 11 is located on the side 14 of the main cover 10, the outlet hole 12 is located in the recess 13 of the main cover 10, and the inclined baffle 211 extends obliquely downward.
[0049] Please refer to Figure 5 , Figure 5 yes Figure 4 Enlarged view of part A.
[0050] In one embodiment, an exhaust channel 32 is formed between the supplementary cover 20 and the main cover 10. The exhaust channel 32 connects the overflow prevention cavity 31 and the exhaust port 22, and the exhaust channel 32 has at least one bend. When gas carrying foam enters the exhaust channel 32, upon encountering the bend, the gas will change direction due to inertia and continue to move forward. The foam, due to the obstruction at the bend, will break into slurry and gas, thereby achieving further separation of gas and liquid and reducing the amount of slurry carried in the discharged gas.
[0051] Furthermore, an exhaust chamber 34 is formed between the supplementary cover 20 and the main cover 10, and the exhaust chamber 34 connects the exhaust channel 32 and the exhaust hole 22. The exhaust chamber 34 can serve as a place to collect residual slurry. For slurry that is not completely collected in the exhaust channel 32, it will be intercepted after flowing into the exhaust chamber 34 with the gas, thereby preventing the slurry in the exhaust channel 32 from flowing out with the gas.
[0052] like Figure 5 In the illustrated embodiment, the exhaust passage 32 has two bends. Specifically, the center cover has an annular groove 24, and the main cover 10 also includes a first enclosure 15, which is received within the annular groove 24 and forms a gap with the inner wall of the annular groove 24, dividing the annular groove 24 into a first passage 321 extending in a first direction, a second passage 322 extending in a second direction, and a third passage 323 extending in the first direction. The first passage 321 is directly connected to the overflow chamber 31, the second passage 322 is connected to the first passage 321, and the third passage 323 is connected to the second passage 322 and is also connected to the exhaust chamber 34.
[0053] The first direction and the second direction form an angle, which is greater than 0° and less than 180°. Preferably, the angle is 90°, the first direction can be vertical (up and down), and the second direction can be horizontal. Of course, the angle can also be 30°, 40°, 50°, 60°, 70°, 80°, 100°, 110°, 120°, 130°, 140°, etc.
[0054] Furthermore, the main cover 10 includes a second enclosure 16, and an exhaust chamber 34 is formed between the second enclosure 16 and the annular groove 24.
[0055] In one embodiment, the main cover 10 further includes a snap-fit seat 17 disposed on the outer periphery of the fourth enclosure, and the additional cover 20 includes a snap-fit connector 25, which is rotatably snapped into the snap-fit seat 17. The snap-fit seat 17 may include a buckle, and the snap-fit connector 25 may include a slot, but are not limited thereto.
[0056] The rotating and clamping mode has certain positioning function. When the rotating and clamping joint 25 is screwed into the rotating and clamping seat 17, it will be matched according to a specific rotating track and angle, so that the additional cover 20 and the main cover 10 can be accurately installed in place. In this way, not only the stability of the connection between the two is ensured, but also the position and shape of the anti-overflow cavity 31 and other related structures (such as the exhaust passage 32, etc.) formed between them meet the design requirements, which is beneficial to the cooperation of various parts and avoids abnormal functional conditions caused by assembly errors.
[0057] In one embodiment set, the main cover 10 further comprises a locally protruding handle buckle part 18, which is used to buckle with the handle 42.
[0058] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
