Exhaust assembly and food processor

Abstract

The application provides an exhaust assembly and a food processor. The exhaust assembly comprises a main body and a convex part which can be elastically moved up and down. The main body has an exhaust passage which penetrates up and down. The convex part is arranged on the inner side wall of the main body, extends from one side of the main body to the other side, and has a gap between the other side of the main body. In this way, the convex part blocks the exhaust passage, reduces the area through which the gas in the exhaust passage can flow, and slows down the exhaust speed, thereby reducing noise propagation. Meanwhile, when the gas flow is large, the gas can push the convex part to produce elastic deformation upward, thereby reducing the blocking of the convex part to the exhaust passage and realizing rapid exhaust.

Description

Technical Field

[0001] This application relates to the field of food processing, and more particularly to a venting assembly and a food processor. Background Technology

[0002] As people's living standards continue to improve, many different types of food processors have appeared on the market. The functions of a food processor can include, but are not limited to, making soy milk, juicing, rice paste, mincing meat, shaved ice, making coffee, and / or preparing face masks. Food processors can include machines that pulverize and blend food, such as soy milk makers, blenders, or high-speed blenders.

[0003] Food processors generate significant noise when processing food. Existing food processors' exhaust systems allow noise to propagate through the exhaust mechanism, impacting the user experience. Utility Model Content

[0004] This application provides a venting assembly and a food processor to solve at least one of the above-mentioned technical problems.

[0005] This application provides an exhaust assembly, including a main body and a protrusion that can be elastically moved up and down. The main body has an exhaust channel that runs vertically through it. The protrusion is disposed on the inner sidewall of the main body and extends from one side of the main body to the other side within the exhaust channel, and has a gap with the other side of the main body.

[0006] In this way, by obstructing the exhaust channel with the protrusion, the area on which gas can flow in the exhaust channel is reduced, slowing down the exhaust speed and thus reducing noise transmission. At the same time, using this exhaust component reduces the noise transmitted to the outside world during the operation of the food processor, improving its noise reduction effect.

[0007] Optionally, the protrusion includes a connecting portion and a blocking portion, the connecting portion connecting the blocking portion to the main body portion, and the dimension of the connecting portion in the thickness direction being smaller than the dimension of the blocking portion in the thickness direction.

[0008] Thus, during the elastic up-and-down movement of the protrusion, the connecting part deforms and can bend. The connecting part deforms more easily than the blocking part. The gas can push open the protrusion, causing it to elastically deform upward from the connecting part, opening the exhaust passage as high as possible and reducing the obstruction of the exhaust passage by the protrusion, thereby achieving rapid exhaust.

[0009] Optionally, the top surface of the blocking portion is higher than the top surface of the connecting portion.

[0010] Thus, when the gas pushes open the protrusion, it causes the protrusion to elastically deform upwards from the connecting part. This design makes it easier for the protrusion to elastically deform upwards.

[0011] Optionally, the bottom surface of the blocking part is flush with the bottom surface of the connecting part.

[0012] This makes the lower surface of the protrusion smoother, making it easier for the gas to push open the protrusion and exhaust when it flows upward.

[0013] Optionally, the protrusion is located at the lower part of the main body.

[0014] In this way, when the gas pushes open the protrusion, it is buffered by the exhaust channel above the protrusion, reducing the splashing generated by the exhaust assembly.

[0015] Optionally, the protrusion and the main body are made of silicone and are integrally molded.

[0016] In this way, the protrusion has good flexibility and can easily deform elastically up and down. Furthermore, the protrusion and the main body can be processed as a whole in one go, simplifying the manufacturing process of the exhaust assembly.

[0017] Optionally, the exhaust assembly further includes a support portion disposed within the exhaust channel, the support portion extending vertically within the exhaust channel, and the support portion connecting to the inner side of the main body on opposite sides in the horizontal direction, thereby dividing the exhaust channel into at least two sub-channels.

[0018] In this way, the support portion provides support to the main body in the direction of its connection to the main body, reducing deformation of the exhaust assembly and minimizing the narrowing of the exhaust channel. Furthermore, when one sub-channel becomes blocked, the other sub-channel remains unobstructed, thus achieving the desired exhaust effect of the exhaust assembly.

[0019] Optionally, the exhaust assembly has a larger dimension in the second direction than in the first direction, and the support portion connects the two inner sides of the main body portion opposite to each other in the first direction, wherein the extension direction of the exhaust channel is the second direction, and the first direction and the second direction are perpendicular to each other in the horizontal plane.

[0020] Thus, the main body is prone to deformation due to heat on opposite sides in the first direction, and the support can expand the opposite sides in the first direction to reduce the shrinkage of the exhaust channel.

[0021] Optionally, the support portion extends from the bottom end of the main body portion toward the top end, and the top end of the support portion is lower than the top end of the main body portion.

[0022] In this way, the main body can be supported by the supporting parts in both the vertical and horizontal directions, thereby reducing the overall deformation of the main body.

[0023] Optionally, each of the sub-channels may be provided with a protrusion.

[0024] In this way, the protrusion and the support can avoid each other. When the support extends to the top and bottom of the main body, it can ensure that the main body can be supported by the support in both the vertical and horizontal directions. At the same time, by setting the protrusion to block the exhaust channel, the area in which gas can flow in the exhaust channel is reduced, the exhaust speed is slowed down and the splashing generated by the exhaust component is reduced. At the same time, the noise transmitted to the outside by the food processor using the exhaust component during operation is reduced, thus improving the noise reduction effect of the food processor.

[0025] Optionally, the support portion and the main body portion are made of silicone material and are integrally molded.

[0026] In this way, the support and main body can be machined as a whole in one go, simplifying the manufacturing process of the exhaust assembly.

[0027] Optionally, the exhaust assembly further includes a reinforcing member located inside the main body, the reinforcing member having a harderness than the main body.

[0028] In this way, by providing support to the main body through the reinforcing members, the deformation of the exhaust assembly is reduced, thus making the exhaust passage smaller.

[0029] Optionally, the inner side of the main body is recessed with a mounting groove, the reinforcing member is held in the mounting groove, and the inner wall of the reinforcing member facing the exhaust channel is flush with the upper and lower edges of the mounting groove.

[0030] This makes the inside of the exhaust passage smooth, reducing the risk of residue and dust adhering to the exhaust passage and making it easier to clean.

[0031] Optionally, the mounting groove extends circumferentially along the main body, and the reinforcing member is annular.

[0032] In this way, the reinforcing member provides support to the main body in the circumferential direction, thus better reducing the deformation of the exhaust assembly.

[0033] Optionally, the protrusion is located below the reinforcing member.

[0034] In this way, the protrusion avoids the reinforcing member, simplifying the exhaust assembly structure. At the same time, the exhaust channel above the protrusion can be made longer, which buffers the gas and reduces splashing generated when passing through the exhaust assembly.

[0035] Optionally, the main body is a silicone body and the reinforcing member is a metal reinforcing member.

[0036] In this way, the metal support is less prone to deformation, providing support for the main body and reducing the deformation of the exhaust components.

[0037] Optionally, this application also includes a food processor comprising:

[0038] Base;

[0039] The stirring cup assembly is assembled on the base;

[0040] A lid assembly, positioned above the stirring cup assembly, includes a lid body and vent holes extending vertically through the lid body; and

[0041] The aforementioned exhaust assembly is disposed within the exhaust port.

[0042] Thus, when the pressure inside the blending jar assembly is low, the protrusion blocks the venting channel, reducing the area where gas can flow, slowing down the venting speed, and reducing splashing during operation. This also reduces noise transmitted to the outside environment, improving the blender's noise reduction effect. When the pressure inside the blending jar assembly is high, the internal gas pushes open the protrusion, causing it to elastically deform upwards. This reduces the obstruction of the venting channel and allows for rapid venting.

[0043] Optionally, the base includes a base and a support extending upward from the base; the stirring cup assembly is detachably assembled to the base.

[0044] In this way, the overall height of the food processor is lower, saving space and making it compact and exquisite.

[0045] Optionally, the cover assembly includes a machine cover and a cup cover. The cup cover is placed on top of the mixing cup assembly. The machine cover is movably disposed on the top of the support base and can cover the cup cover. The vent includes a first vent penetrating the machine cover and a second vent penetrating the cup cover. The venting assembly is located at the first vent. When the machine cover is placed on the cup cover, the venting assembly is aligned and sealed with the second vent.

[0046] In this way, a single exhaust component can achieve a seal between the first exhaust port and the second exhaust port, eliminating the need to set separate sealing structures for the first and second exhaust ports, thus simplifying the structure of the food processor.

[0047] Optionally, the exhaust assembly is located within the second exhaust port, which is funnel-shaped.

[0048] In this way, when the cover is closed, the bottom of the exhaust assembly can be easily inserted into the second exhaust port to avoid the problem of seal failure due to improper assembly.

[0049] Optionally, the outer wall of the main body is provided with a first sealing lip and a second sealing lip. The first sealing lip is located above the second vent hole. In the horizontal direction, the free end of the first sealing lip extends beyond the free end of the second sealing lip. Both the first sealing lip and the second sealing lip are fitted and sealed to the inner wall of the second vent hole.

[0050] Thus, when the first sealing lip and the second sealing lip are fitted and sealed against the inner wall of the second vent hole, elastic deformation will occur, improving the sealing effect with the inner wall of the vent hole.

[0051] Optionally, the outer side wall of the main body is provided with a first lower abutment, and the lower end of the first exhaust hole of the cover is provided with a second lower abutment. The first lower abutment is located below the second lower abutment and abuts against the second lower abutment.

[0052] This prevents the exhaust assembly from being lifted up by the cup lid and detached from the lid when the lid is closed.

[0053] Optionally, the outer side wall of the main body of the exhaust assembly is provided with a protruding rib that abuts against the inner side wall of the exhaust port.

[0054] This increases the stability of the exhaust assembly and improves the sealing effect with the inner wall of the exhaust port.

[0055] Optionally, the top of the exhaust assembly is provided with an annular blocking edge that abuts against the inner sidewall of the top of the exhaust port.

[0056] This increases the stability of the exhaust assembly and improves the sealing effect with the inner wall of the exhaust port. Attached Figure Description

[0074] Where there is no conflict, the features in the following embodiments and implementations can be combined with each other.

[0075] Example 1

[0076] This embodiment provides a food processor 100, which can be used to make soy milk, rice paste, juice, etc. The food processor 100 includes a base 10, a blending cup assembly 20, and a lid assembly 30. In some embodiments, the food processor 100 also includes a control assembly 50.

[0077] See Figure 1 As shown, the base 10 includes a base 11 and a support 12 extending upward from the base 11. The support 12 and the base 11 can be integrally formed, or they can be formed separately and then assembled together. The top view of the base 10 can be circular, rectangular (with rounded corners), square (with rounded corners), polygonal (with rounded corners), elliptical, etc. The top view of the mixing cup assembly 20 can be the same as or different from the shape of the base 10.

[0078] The mixing cup assembly 20 is assembled to the base 10. The mixing cup assembly 20 includes a mixing cup 21, a heating plate 23 disposed at the bottom of the mixing cup 21, and a cutter assembly 22. In some embodiments, the mixing cup assembly 20 is detachably assembled to the base 11. In other embodiments, the mixing cup assembly 20 includes a mixing cup 21, a chassis disposed at the bottom of the mixing cup 21, and a cutter assembly 22. The heating element can be disposed on the base 11, and the heat is conducted from the heating element to the chassis to heat the ingredients in the mixing cup 21. The mixing cup 21 is used to place the ingredients, the heating plate 23 is used to heat the ingredients in the mixing cup 21, and the cutter assembly 22 is used to beat and crush the ingredients in the mixing cup 21. The mixing cup 21 includes a cup body 211 and a handle. The cup body 211 is provided with a cup spout 213, and the cup spout 213 is disposed opposite to the handle. The support base 12 is provided with a mating groove corresponding to the cup spout 213, and the cup spout 213 is located in the mating groove. The cross-section of the cup body 211 can be set to be square, that is, the orthographic projection of the cup body 211 in the horizontal plane is square. The mixing cup 21 is a square cup. In this way, the mixing cup 21 can be made shorter and still have the same volume. R corners can be provided at the square corners. Turbulence ribs can be provided at the four corners of the mixing cup 21, or the turbulence ribs can be not provided. In other embodiments, the cross-section of the cup body 211 can also be set to be circular or other shapes.

[0079] See Figure 3 As shown, the lid assembly 30 is covered above the mixing cup assembly 20, and includes a lid body 33 and an exhaust hole 34 penetrating through the lid body 33 up and down. The exhaust component 40 is disposed in the exhaust hole 34. In this embodiment, the exhaust component 40 is detachably disposed in the exhaust hole 34. The lid assembly 30 includes a machine lid 31 and a cup lid 32. The cup lid 32 is covered above the mixing cup assembly 20. The machine lid 31 is movably disposed at the top of the support base 12 and can be covered above the cup lid 32. The exhaust hole 34 includes a first exhaust hole 341 penetrating through the machine lid 31 and a second exhaust hole 342 penetrating through the cup lid 32. In the state where the machine lid 31 is covered on the cup lid 32, the exhaust component 40 is located in the first exhaust hole 341 and the second exhaust hole 342. In other embodiments, the exhaust component 40 can also be fixedly disposed in the exhaust hole.

[0080] The machine lid 31 is assembled to the support base 12, and the machine lid 31 is covered above the mixing cup assembly 20. The base 10 and the machine lid 31 present a "C" shape, and the three sides wrap the mixing cup assembly 20, so as to reduce the reflected noise outside the base 10 of the noise generated inside the mixing cup assembly 20.

[0081] In some embodiments, the lid 31 is movably disposed over the mixing cup assembly 20. The lid 31 is rotatably assembled to the support base 12. In another embodiment, the lid 31 is rotatably assembled to the support base 12 in a horizontal direction. In another embodiment, the lid 31 is detachably assembled to the support base 12. In yet another embodiment, the lid 31 is vertically connected to the support base 12.

[0082] In another embodiment, the cover 31 is fixed to the support base 12, and the stirring cup assembly 20 is pushed into the base 10 from the side or the front.

[0083] In some embodiments, the control component 50 is disposed on the cover assembly 30 and / or the support base 12, for displaying information such as function and time, and for user operation, such as selecting a cooking function, starting / pausing the cooking process, etc. In the related "L"-shaped blender 100, the base 11 protrudes horizontally from the blending cup assembly 20, and the control component 50 is disposed on the upper surface of the protruding portion. Compared with the related technology, the control component 50 of this application is disposed on the cover assembly 30 and / or the support base 12, and the blender 100 occupies less space in the horizontal direction overall. The "U"-shaped blender 100 further reduces the overall space ratio of the machine; the "U"-shaped blender 100 can be smaller and thinner through a better arrangement of electrical components.

[0084] The control component 50 is located on the cover component 30, making it convenient for the user to operate without bending over. It is also closer to the user's eyes, improving visibility of the information on the control component 50. A power supply component 60 is housed within the support base 12, and the control component 50 is electrically connected to the power supply component 60. The power supply component 60 is used to connect to an external power source to power the blender 100 and the control component 50. The motor is located within the base 11 or at the bottom of the blending cup 21. The motor includes a motor shaft, and the blade assembly 22 is located at the top of the motor shaft. In one embodiment, the motor is a brushless motor without a rear end cover, resulting in a lower motor height and reducing the overall height of the blender 100. In other embodiments, the motor can be a conventional brushed motor or a brushless motor.

[0085] Since the power supply component 60 is located inside the support base 12 and the control component 50 is located inside the cover 31, the power supply component 60, control component 50 and motor are not stacked together. By reasonably arranging the positions of the three, the height of the food processor 100 can be effectively reduced, so that the overall height of the food processor 100 is no more than millimeters, making it more compact and exquisite. In this way, the vibration generated by the food processor 100 during operation can be reduced, and it occupies less space.

[0086] In another embodiment, both the power supply component 60 and the control component 50 are disposed within the cover 31. The power supply component 60 and the control component 50 can be integrated or disposed separately. The motor is disposed within the base 11 or at the bottom of the blending cup 21, which also reduces the height of the food processor 100. In another embodiment, both the power supply component 60 and the control component 50 are disposed within the support base 12. The power supply component 60 and the control component 50 can be integrated or disposed separately, with the motor disposed within the base 11 or at the bottom of the blending cup 21. In another embodiment, the power supply component 60 is disposed within the base 11, the control component 50 is disposed within the support base 12, and the motor is disposed within the base 11 or at the bottom of the blending cup 21. In another embodiment, the control component can be disposed within the base 11, and the power supply component 60 can be disposed within the base 11, the support base 12, or the cover 31. In yet another embodiment, both the power supply component 60 and the control component 50 are disposed within the cover 31, and the motor is disposed within the cup lid 32. In another embodiment, the power supply component 60 is disposed within the support base 12, the control component 50 is disposed within the lid 31, and the motor is disposed within the cup lid 32. In other embodiments, the control component 50 may be disposed within both the lid 31 and the support base 12. The control component 50 may include multiple circuit boards, which, by being distributed, facilitate setup and enable more control functions of the food processor 100.

[0087] See Figure 2 , Figure 4 and Figure 5 As shown, the exhaust assembly 40 includes a main body 41 and a protrusion 42 that can move up and down elastically. The main body 41 has an exhaust channel 412 that runs through it vertically. The protrusion 42 is disposed on the inner sidewall of the main body 41 and extends from one side of the main body 41 to the other side within the exhaust channel 412, and has a gap with the other side of the main body 41.

[0088] Thus, when the pressure inside the blending cup assembly 20 is low, the protrusion 42 blocks the exhaust channel 412, reducing the area where gas can flow in the exhaust channel 412, slowing down the exhaust speed, and reducing the noise transmitted to the outside by the blending cup assembly 20 during operation, thereby improving the noise reduction effect of the food processor 100. The protrusion 42 also reduces splashing generated during the operation of the food processor 100. When the pressure inside the blending cup assembly 20 is high, the internal gas pushes open the protrusion 42, causing the protrusion 42 to elastically deform upwards, thereby reducing the obstruction of the exhaust channel 412 by the protrusion 42 and achieving rapid exhaust.

[0089] In an optional embodiment, see Figure 6As shown, the protrusion 42 includes a connecting portion 421 and a blocking portion 422. The connecting portion 421 connects the blocking portion 422 and the main body portion 41, and the dimension of the connecting portion 421 in the thickness direction Z is smaller than the dimension of the blocking portion 422 in the thickness direction Z.

[0090] This allows the connecting part 421 to deform during the elastic up-and-down movement of the protrusion 42, enabling it to bend. The connecting part 421 deforms more easily than the blocking part 422. When the internal pressure of the stirring cup assembly 20 is high, the internal gas pushes open the protrusion 42, causing it to elastically deform upwards from the connecting part 421. This allows the protrusion 42 to open the exhaust channel 412 as high as possible, reducing its obstruction and enabling rapid exhaust.

[0091] In an optional embodiment, see Figure 6 As shown, the top surface of the blocking part 422 is higher than the top surface of the connecting part 421. When the pressure inside the stirring cup assembly 20 is high, the gas inside the stirring cup assembly 20 pushes open the protrusion 42, causing the protrusion 42 to elastically deform upward from the connecting part 421. This arrangement makes it easier for the protrusion 42 to elastically deform upward.

[0092] In an optional embodiment, see Figure 6 As shown, the bottom surface of the blocking part 422 is flush with the bottom surface of the connecting part 421. This makes the side of the protrusion 42 facing the bottom of the stirring cup 21 smoother. When the pressure inside the stirring cup assembly 20 is high, the gas inside the stirring cup assembly 20 flows upward, making it easier to push open the protrusion 42 to exhaust gas.

[0093] In other embodiments, the top surface of the blocking portion 422 may be flush with the top surface of the connecting portion 421, in which case the bottom surface of the blocking portion 422 is lower than the bottom surface of the connecting portion 421. In still other embodiments, the top surface of the blocking portion 422 is higher than the top surface of the connecting portion 421, while the bottom surface of the blocking portion 422 is lower than the bottom surface of the connecting portion 421.

[0094] In an optional embodiment, see Figure 2 , Figure 4 and Figure 5 As shown, the protrusion 42 is located at the lower part of the main body 41. In other embodiments, the protrusion 42 may also be located at the middle of the main body 41 in the vertical direction Z. When the pressure inside the stirring cup assembly 20 is high, when the gas inside the stirring cup assembly 20 pushes open the protrusion 42, the gas is buffered by the exhaust channel 412 above the protrusion 42, reducing splashing generated by the exhaust assembly 40.

[0095] In an optional embodiment, the protrusion 42 and the main body 41 are made of silicone and are integrally molded. Thus, the protrusion 42 has good flexibility, easily deforms elastically upwards and downwards, and the protrusion 42 and the main body 41 can be processed as a single unit, simplifying the manufacturing process of the exhaust assembly 40.

[0096] In an optional embodiment, see Figure 2 , Figure 4 and Figure 5 As shown, the exhaust assembly 40 also includes a reinforcing member 432, which is located inside the main body 41. The hardness of the reinforcing member 432 is greater than that of the main body 41. The reinforcing member 432 provides support to the main body 41, reducing deformation of the exhaust assembly 40 and making the exhaust passage 412 smaller.

[0097] In an optional embodiment, see Figure 2 , Figure 4 and Figure 5 As shown, the inner side of the main body 41 is recessed with a mounting groove 411, and the reinforcing member 432 is held in the mounting groove 411. The inner side wall of the reinforcing member 432 facing the exhaust channel 412 is flush with the upper and lower edges of the mounting groove 411.

[0098] This makes the inside of the exhaust passage 412 smooth, reducing the risk of residue and dust adhering to the inside of the exhaust passage 412 and making it easier to clean the exhaust passage 412.

[0099] In an optional embodiment, see Figure 2 , Figure 4 and Figure 5 As shown, the mounting groove 411 extends circumferentially along the main body 41, and the reinforcing member 432 is annular.

[0100] Thus, the reinforcing member 432 provides support for the main body 41 in the circumferential direction, thereby better reducing the deformation of the exhaust assembly 40.

[0101] In other embodiments, the mounting groove 411 may also have one or more segments in the circumferential direction of the main body 41, and the reinforcing member 432 matches the shape of the mounting groove 411, so that the reinforcing member 432 provides local support for the main body 41.

[0102] In an optional embodiment, the protrusion 42 is disposed below the reinforcement 432.

[0103] In this way, the protrusion 42 avoids the reinforcing member 432, simplifying the structure of the exhaust assembly 40. At the same time, the exhaust channel 412 above the protrusion 42 can be made longer, and the gas is buffered by the exhaust channel 412 above the protrusion 42, reducing the splashing generated by the exhaust assembly 40.

[0104] In an optional embodiment, the main body 41 is a silicone main body 41, and the reinforcing member 432 is a metal reinforcing member 432. Specifically, the reinforcing member 432 is made of stainless steel.

[0105] In this way, the metal reinforcement 432 is not easily deformed, and can provide support for the main body 41, reducing the deformation of the exhaust assembly 40; and the silicone main body 41 has good elasticity, which can better abut against the inner wall of the exhaust hole 34, thereby improving the sealing between the exhaust assembly 40 and the exhaust hole 34.

[0106] In one embodiment, see Figure 2 , Figure 4 and Figure 5 As shown, the exhaust assembly 40 is located inside the second exhaust port 342, which is funnel-shaped. When the cover 31 is closed, it is convenient for the bottom of the exhaust assembly 40 to be inserted into the second exhaust port 342, so as to avoid the problem of sealing failure due to improper assembly.

[0107] In an optional embodiment, see Figure 2 , Figure 4 and Figure 5 As shown, a first sealing lip 44 and a second sealing lip 45 are provided on the outer wall of the main body 41. The first sealing lip 44 is located above the second sealing lip 45, and in the horizontal direction, the free end of the first sealing lip 44 extends beyond the free end of the second sealing lip 45. Both the first sealing lip 44 and the second sealing lip 45 are fitted and sealed against the inner wall of the second vent 342. When the first sealing lip 44 and the second sealing lip 45 are fitted and sealed against the inner wall of the second vent 342, elastic deformation occurs, improving the sealing effect with the inner wall of the vent 34. The arrangement of the first sealing lip 44 and the second sealing lip 45 provides two seals to ensure a sealing effect.

[0108] In an optional embodiment, see Figure 4 As shown, the outer side wall of the main body 41 of the exhaust assembly 40 is provided with a protruding rib 46 to abut against the inner side wall of the first exhaust hole 341, thereby increasing the assembly stability of the exhaust assembly 40 and improving the sealing effect with the inner side wall of the exhaust hole 34.

[0109] In an optional embodiment, the outer side wall of the main body 41 is provided with a first lower abutment 48, and the lower end of the first exhaust hole 341 of the cover 31 is provided with a second lower abutment 3411. The first lower abutment 48 is located below the second lower abutment 3411 and abuts against the second lower abutment 3411, which can prevent the bottom of the exhaust assembly 40 from tilting up; it can also prevent the exhaust assembly 40 from being pushed upward by the cup lid 32 and detached from the cover 31 when the cover 31 is closed.

[0110] The rib 46, the first lower stop 48, the first sealing lip 44, and the second sealing lip 45 are arranged sequentially from top to bottom along the height direction of the sealing structure.

[0111] In one embodiment, the first lower abutment portion 48 extends in a ring shape along the circumferential direction of the main body portion 41. In another embodiment, at least two disconnected first lower abutment portions 48 may also be provided along the circumferential direction of the seal.

[0112] In one embodiment, the second lower stop portion 3411 may also be annular.

[0113] In an optional embodiment, the top of the exhaust assembly 40 is provided with an annular blocking edge 49, which abuts against the inner sidewall of the top of the exhaust port 34. This increases the stability of the exhaust assembly 40 and improves the sealing effect with the inner sidewall of the exhaust port 34.

[0114] Example 2

[0115] The food processor 100 in this embodiment has a similar structure to the food processor 100 in Embodiment 1. The main difference lies in the implementation details. (See attached image.) Figure 7 , Figure 11 and Figure 12 As shown, the exhaust assembly 40 of the food processor 100 includes a support portion 431 disposed in the exhaust channel 412. The support portion 431 extends vertically within the exhaust channel 412. The support portion 431 connects to the inner side of the main body portion 41 on opposite sides in the horizontal direction, dividing the exhaust channel 412 into at least two sub-channels 413 in the horizontal direction.

[0116] In this way, the support portion 431 supports the main body portion 41 in the direction of its connection to the main body portion 41, reducing the deformation of the exhaust assembly 40 and the reduction of the size of the exhaust passage 412. Moreover, when one side of the sub-passage is blocked, the other side of the sub-passage 413 can remain unobstructed, thereby achieving the exhaust effect of the exhaust assembly 40.

[0117] In an optional embodiment, see Figures 8-10 As shown, the exhaust assembly 40 has a larger dimension in the second direction Y than in the first direction X. The support portion 431 connects the two opposing inner surfaces of the main body portion 41 in the first direction X. The exhaust channel 412 extends in the second direction Y. The first direction X and the second direction Y are perpendicular to each other in the horizontal plane. The second direction Y is one of the length and width directions of the cover assembly 30, and the first direction X is the other of the length and width directions of the assembly.

[0118] Thus, the two opposite sides of the main body 41 in the first direction are easily deformed by heat, and the support 431 can expand the two opposite sides in the first direction X to reduce the shrinkage of the exhaust channel 412.

[0119] In an optional embodiment, see Figure 11 and Figure 12 As shown, the support portion 43 extends to the top and bottom of the main body portion 41, and the top of the support portion 431 is lower than the top of the main body portion 41.

[0120] In this way, the main body 41 can be supported by the support part 431 in the vertical Z direction, thereby reducing the overall deformation of the main body 41.

[0121] In an optional embodiment, see Figure 11 As shown, each sub-channel 413 is provided with a protrusion 42.

[0122] In this way, the protrusion 42 and the support 431 can avoid each other. When the support 431 extends to the top and bottom of the main body 41, it can ensure that the main body 41 can be supported by the support 431 in the vertical Z direction. At the same time, by setting the protrusion 42 to block the exhaust channel 412, the area in which gas can flow in the exhaust channel 412 is reduced, the exhaust speed is slowed down and the splash generated during the operation of the food processor 100 is reduced. At the same time, the noise transmitted to the outside by the mixing cup assembly 20 during the operation is reduced, and the noise reduction effect of the food processor 100 is improved.

[0123] In an optional embodiment, the support portion 43 and the main body portion 41 are made of silicone and are integrally molded.

[0124] In this way, the support part 431 and the main body part 41 can be processed as a whole in one go, simplifying the manufacturing process of the exhaust assembly 40. The main body part 41 is made of silicone, which is easily deformed by heat. The support part 431 can play a supporting role, which can reduce the deformation of the main body part 41 that would cause the exhaust channel 412 to become smaller, thus preventing it from affecting the exhaust.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
