Description

Technical Field

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

[0002] With the continuous improvement of people's living standards, many different types of food processors have appeared on the market. The functions of food processors mainly 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 soy milk makers, blenders, or high-speed blenders—machines that pulverize and mix food. Existing food processors use an exhaust vent, which only provides venting functionality and not sealing, making it easy for air and moisture to enter the vent, and in severe cases, even causing liquid to overflow and enter the vent. Utility Model Content

[0003] This application provides a lid assembly and a food processor, the sealing structure of which has both sealing and venting functions, and is easy to assemble.

[0004] This application provides a lid assembly for covering the blending cup of a food processor. The lid assembly includes a lid body and a sealing structure. The lid body has an assembly hole, and the sealing structure is detachably assembled into the assembly hole. The sealing structure has an exhaust channel that connects the internal space of the blending cup with the external space. The sealing structure includes a sealing element and a support element located within the sealing element. The hardness of the support element is greater than the hardness of the sealing element. The sealing element is fitted and sealed to the inner wall of the assembly hole.

[0005] The sealing structure of the above technical solution provides venting function through the venting channel and sealing function through the sealing element fitting against the inner wall of the assembly hole, so that the sealing structure has both venting and sealing functions; the setting of the support element increases the rigidity of the sealing structure, making the sealing structure easier to assemble and preventing deformation, thereby reducing the probability of blockage; the structure of the sealing structure is relatively simple, which makes the structure of the food processor correspondingly simple, and at the same time, the sealing structure is also easier to clean.

[0006] Furthermore, the sealing structure is assembled into the assembly hole from top to bottom.

[0007] The sealing structure of the above technical solution allows for easy assembly and disassembly of the sealing structure without opening or removing the cover assembly, thus improving the convenience of cleaning the sealing structure.

[0008] Furthermore, the bottom of the sealing structure is narrowed.

[0009] When the sealing structure of the above technical solution is assembled from top to bottom into the assembly hole, the bottom of the sealing structure is easy to insert into the assembly hole, making it easier to assemble the sealing structure.

[0010] Furthermore, the seal includes an upper abutment portion that protrudes from the top of the cover body and abuts against the top of the cover body.

[0011] The upper stop portion of the above technical solution can prevent the sealing structure from being improperly assembled; it can also be gripped to facilitate the removal of the sealing structure.

[0012] Furthermore, the cover assembly includes a machine cover and a cup cover. The cup cover is placed over the blending cup of the food processor, and the machine cover is placed over the cup cover. The assembly hole includes a first assembly hole penetrating the machine cover and a second assembly hole penetrating the cup cover. The bottom end of the sealing structure extends beyond the first assembly hole and is assembled into the second assembly hole. The sealing element is fitted and sealed to the inner wall of the second assembly hole.

[0013] The above-mentioned technical solution features a separate lid and cup lid, which facilitates processing and molding. The cup lid can be removed for separate cleaning, making it not only convenient but also more thorough. After the ingredients are prepared, the cup lid still protects the ingredients from spillage and prevents burns from the heat. The cup lid also protects against dust, making it more user-friendly. The bottom of the sealing structure extends beyond the first assembly hole and is assembled into the second assembly hole, resulting in a better sealing effect.

[0014] Furthermore, the outer wall of the seal is provided with a first sealing lip and a second sealing lip, the second assembly hole is funnel-shaped, the first sealing lip is located above the second sealing lip and its free end extends beyond the free end of the second sealing lip, and both the first sealing lip and the second sealing lip are fitted and sealed to the inner wall of the second assembly hole.

[0015] When the first and second sealing lips of the above technical solution are fitted and sealed against the inner wall of the second assembly hole, elastic deformation will occur to improve the sealing effect.

[0016] Furthermore, the outer wall of the seal is provided with a protruding rib to abut against the inner wall of the first assembly hole.

[0017] The ribs in the above technical solution increase the stability of the sealing structure and prevent shaking, so as not to affect the sealing effect.

[0018] Furthermore, the seal includes a first lower abutment portion, and the cover includes a second lower abutment portion, wherein the first lower abutment portion is located below the second lower abutment portion and abuts against the second lower abutment portion.

[0019] The first and second lower abutting parts of the above technical solution abut against each other, which can prevent the bottom of the sealing structure from tilting up; it can also prevent the sealing structure from being pushed up by the cup lid and detached from the machine cover when the machine cover is closed.

[0020] Furthermore, the cover includes a cover housing and a panel. The cover housing includes a surrounding rib located below the panel. The first assembly hole includes a third assembly hole formed by the surrounding rib and a fourth assembly hole disposed on the panel.

[0021] The cover of the above technical solution is easy to process and form.

[0022] Furthermore, the sealing element includes a limiting hole, the support element is located within the limiting hole, and the support element forms part of the exhaust channel.

[0023] The sealing structure of the above technical solution is easy to process and form.

[0024] Furthermore, the sealing element includes an upper boss and a lower boss, the upper boss being located above the support member and the lower boss being located below the support member.

[0025] The upper and lower bosses in the above technical solution increase the stability of the support and prevent it from falling off.

[0026] This application also provides a food processor, including a base, a blending cup, and a lid assembly. The base includes a base and a support extending upward from the base. The lid assembly is connected to the support and covers the blending cup.

[0027] Furthermore, the support base is provided with a power supply component, and the cover assembly is provided with a control component that is electrically connected to the power supply component.

[0028] The above-mentioned technical solution avoids stacking the power supply components, control components, and motor together in the food processor. By rationally arranging the positions of the three components, the height of the food processor can be effectively reduced, making it more compact and exquisite. This reduces the vibration generated during the operation of the food processor and occupies less space. Attached Figure Description

[0051] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0052] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. 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.

[0053] Figures 1 to 10 The diagram shown is a schematic representation of the first embodiment of the food processor of this application. Please refer to [link / reference]. Figures 1 to 3 The food processor 100 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 50. The base 10 includes a base 11 and a support base 12 extending upward from the base 11. The support base 12 and the base 11 can be integrally formed, or they can be formed separately and then assembled together.

[0054] Please see Figures 1 to 7, the mixing cup assembly 20 is assembled to the base 11. The cover assembly 50 is rotatably or detachably connected to the support base 12, facilitating the assembly of the mixing cup assembly 20. The mixing cup assembly 20 includes a mixing cup 21, a heating plate 22 disposed at the bottom of the mixing cup 21, and a blade assembly 23. The support base 12 is located on the front side of the mixing cup 21. The heating plate 22 is disposed at the bottom of the mixing cup 21, with higher heating efficiency and better heating effect.

[0055] The mixing cup 21 is used to place ingredients, the heating plate 22 is used to heat the ingredients in the mixing cup 21, and the blade assembly 23 is used to beat and crush the ingredients in the mixing cup 21. The mixing cup 21 includes a cup body 219 and a handle 218. The cup body 219 is provided with a cup spout 2191, and the position of the cup spout 2191 is opposite to that of the handle 218.

[0056] The cover assembly 50 is provided with an exhaust passage 5031 to connect the internal space of the mixing cup 21 with the external space. The exhaust passage 5031 vertically penetrates the cover assembly 50 to connect the internal space of the mixing cup 21 with the external space. The outlet of the exhaust passage 5031 is arranged upward. The steam generated when the ingredients in the mixing cup 21 are heated is discharged through the exhaust passage 5031 to achieve the exhaust function.

[0057] The cover assembly 50 includes a machine cover 30 and a cup cover 25. The cup cover 25 is detachably covered on the mixing cup 21. The machine cover 30 is rotatably connected to the support base 12 and is covered above the cup cover 25. The exhaust passage 5031 penetrates the machine cover 30 and the cup cover 25. In the first embodiment, the machine cover 30 is assembled to the support base 12 so as to be rotatable up and down. In another embodiment, the machine cover 30 is assembled to the support base 12 so as to be rotatable in the horizontal direction.

[0058] Refer Figure 6 , a power supply component 13 is provided in the support base 12, and a control component 31 electrically connected to the power supply component 13 is provided in the cover assembly 50. The food processor 100 includes a motor 40 to drive the blade assembly 23 to rotate to beat the ingredients. The motor 40 is disposed in the base 11 or at the bottom of the mixing cup 21. The motor 40 includes an output shaft 41, and the blade assembly 23 is disposed at the top end of the output shaft 41.

[0059] In one embodiment, the power supply component 13 includes a power supply board, a storage battery, etc.

[0060] Since the power supply component 13 is provided in the support base 12 and the control component 31 is provided in the cover assembly 50, it is avoided to stack the power supply component 13, the control component 31 and the motor 40 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 not greater than 280 mm, making it more compact and delicate. Thus, the vibration generated during the operation of the food processor 100 can be reduced, and it occupies less space.

[0061] In another embodiment, both the power supply component 13 and the control component 31 are disposed within the cover component 50, and the motor 40 is disposed within the base 11 or at the bottom of the mixing cup 21, which can also reduce the height of the cooking machine 100. In yet another embodiment, both the power supply component 13 and the control component 31 are disposed within the machine cover 30, and the motor 40 is disposed within the cup cover 25. In still another embodiment, the power supply component 13 is disposed within the support base 12, the control component 31 is disposed within the machine cover 30, and the motor 40 is disposed within the cup cover 25.

[0062] Please refer to Figure 6 , the cup cover 25 is provided with a magnet 259, and the machine cover 30 is provided with a reed switch 39 corresponding to the magnet 259. When the machine cover 30 is covered on the mixing cup 21, the reed switch 39 closes under the magnetic force of the magnet 259. At this time, the control component 31 can be turned on. When the machine cover 30 is opened, the reed switch 39 disconnects due to being far away from the magnet 259. At this time, the control component 31 cannot be turned on. Thus, it is avoided that the control component 31 is turned on when the machine cover 30 is not properly covered, and the use is safer. The cup cover 25 is disposed below the machine cover 30, which can play a role in heat insulation, avoiding the temperature of the machine cover 30 being too high, thereby protecting the control component 31. In the illustrated embodiment, the cup cover 25 is provided with a recess 255 for the user to grasp conveniently.

[0063] In one embodiment, the knife component 23 is detachably disposed at the bottom of the mixing cup 21. Please refer to Figures 5 to 7 , the motor 40 is disposed at the bottom of the mixing cup 21. The output shaft 41 of the motor 40 passes through the heating plate 22, and a shaft portion 48 is provided at the top of the output shaft 41. The knife component 23 is detachably assembled to the shaft portion 48.

[0064] In another embodiment, the knife component 23 can be fixedly disposed at the bottom of the mixing cup 21.

[0065] Please refer to Figure 8 , the machine cover 30 includes a cover housing 37, a panel 36, and a control board box 35. The control component 31 is disposed within the cover housing 37. The control board box 35 covers the control component 31, and the panel 36 is fixed on the control board box 35. A limiting rib 375 surrounding the panel 36 is provided at the top of the cover housing 37, and the limiting rib 375 plays a role in limiting the panel 3b.

[0066] The material of the panel 36 can be glass, PC, IMD, or PVC, etc., and is not limited thereto.

[0067] Refer to Figures 9 to 11, a power board box 121 is provided inside the support base 12, the power supply component 13 is arranged inside the power board box 121, the support base 12 is provided with a wire hole 122 for the lead wire to pass through and an isolation rib 123 on one side of the wire hole 122, the isolation rib 123 extends to the upper end of the power board box 121, and the power board box 121 is provided with a guiding surface 1211 that docks with the isolation rib 123. When water enters the support base 12 from the wire hole 122, it sequentially passes through the isolation rib 123 and the guiding surface 1211 and then falls, preventing the water from contacting the power supply component 13.

[0068] The middle position of the guiding surface 1211 is high and the two side positions are low, so that the water entering the support base 12 flows to both sides after falling onto the guiding surface 1211 and then falls from both sides. The machine base 10 includes a bottom cover 19 arranged at the bottom, and the bottom cover 19 is provided with a drain hole 191. The water falling from the guiding surface 1211 finally drains out from the drain hole 191. The power board box 121 includes a backstop rib 1214 that presses downward against the bottom cover 19, and a wire clamping groove 1215 is formed between the two backstop ribs 1214.

[0069] See Figures 3 to 4 , Figure 6 and Figure 7 , the motor 40 is fixed to the motor frame 49, a flange 211 is provided on the bottom end of the stirring cup 21 extending radially inward, the heating plate 22 presses downward against the flange 211, the motor frame 49 presses upward against the flange 211, and the motor frame 49 is locked with the heating plate 22. A seal is formed between the heating plate 22 and the flange 211 through a disc seal ring 221. During assembly, first, the disc seal ring 221 is sleeved on the edge of the heating plate 22, then the heating plate 22 is placed into the cup mouth of the stirring cup 21 and pressed against the flange 211 through the disc seal ring 221. Then, the motor frame 49 equipped with a cup seal ring 490 is buckled with the bottom end of the stirring cup 21 from bottom to top, and the motor frame 49 and the heating plate 22 are locked through fasteners, thereby fixing the heating plate 22, the stirring cup 21 and the motor frame 49 together. The assembly is convenient and reliable. In addition, two through grooves 499 are opened on the motor frame 49, the fuse 498 and the thermostat 497 are respectively placed in the two through grooves 499, and the fuse 498 and the thermostat 497 are pressed against the heating plate 22 through a pressing piece 496. The pressing piece 496 is fixed to the motor frame 49 through fasteners, and then the motor 40 is fixed to the motor frame 49.

[0070] The motor frame 49 is equipped with a high-voltage upper coupler 481 and a low-voltage upper coupler 482. The motor 40 includes a motor body 44 and multiple mounting feet 45 disposed on the outside of the motor body 44. The motor 40 is mounted to the motor frame 49 via the mounting feet 45. The high-voltage upper coupler 481 is located between two adjacent mounting feet 45, and the low-voltage upper coupler 482 is located between another two adjacent mounting feet 45. That is, the coupler is split into independent high-voltage upper couplers 481 and low-voltage upper couplers 482, so that the high-voltage upper coupler 481 and low-voltage upper coupler 482 are small enough to be accommodated between two adjacent mounting feet 45, thereby further reducing the height of the food processor 100. After the motor 40, high-voltage upper coupler 481, and low-voltage upper coupler 482 are fixed to the motor frame 49, the cup bottom cover 488 is finally installed, with the high-voltage upper coupler 481 and low-voltage upper coupler 482 passing through the holes provided in the cup bottom cover 488.

[0071] The base 11 has a downwardly recessed groove 111. A high-voltage lower coupler 112 and a low-voltage lower coupler 113 are disposed within the groove 111. The high-voltage lower coupler 112 is connected to the high-voltage upper coupler 481, and the low-voltage lower coupler 113 is connected to the low-voltage upper coupler 482. By placing the high-voltage lower coupler 112 and the low-voltage lower coupler 113 within the groove 111, the height of the base 11 can be reduced, thereby reducing the height of the food processor 100. In one embodiment, two protrusions 118 are provided within the groove 111, and the high-voltage lower coupler 112 and the low-voltage lower coupler 113 are respectively disposed on the two protrusions 118, thereby achieving waterproofing.

[0072] Figure 11 The diagram shown is a schematic representation of a second embodiment of the food processor 100 of this application. This embodiment differs from the first embodiment in that the motor 40 is disposed within the base 11. Other features are the same as those in the above embodiment and will not be repeated here.

[0073] Figure 12 The diagram shown is a schematic representation of a third embodiment of the food processor 100 of this application. In this embodiment, the lid 30 is rotatably mounted on the support base 12, and the cup lid 25 is integrally formed with the lid 30. Thus, the structure of the blending cup assembly 20 is simpler. Other features are the same as in the above embodiments and will not be repeated here.

[0074] Figure 13The diagram shown is a schematic representation of a fourth embodiment of the food processor 100 of this application. In this embodiment, the cup lid 25 and the machine lid 30 are integrally formed, and the lid assembly 50 is detachably assembled to the support base 12. The lid assembly 50 is provided with a first coupler electrically connected to the control assembly 31, and the support base 12 is provided with a second coupler 124 electrically connected to the power supply assembly 13. When the lid assembly 50 is assembled to the support base 12, the first coupler and the second coupler 124 are mated, thereby realizing the electrical connection between the control assembly 31 and the power supply assembly 13. Other features are the same as those in the above embodiments and will not be repeated here.

[0075] Figures 14 to 22 The diagram shown is a fifth embodiment of the food processor 100 of this application. This embodiment differs from the first embodiment in that the lid assembly 50 includes a lid body 502 and a sealing structure 503. (See reference...) Figures 14 to 15 The cover body 502 has an assembly hole 5021. The sealing structure 503 is detachably assembled into the assembly hole 5021. The sealing structure 503 has an exhaust channel 5031. The exhaust channel 5031 connects the internal space of the stirring cup 21 with the external space. Other features are the same as in the above embodiment and will not be described again here.

[0076] In one embodiment, the lid assembly 50 includes an assembly part 500 assembled into the mixing cup 21 of the food processor 100. The assembly part 500 is provided with a lid sealing ring 501, which is fitted and sealed to the inner wall of the mixing cup 21. The steam inside the mixing cup 21 cannot be discharged from the mouth of the mixing cup 21, but can only be discharged from the exhaust channel 5031.

[0077] In one embodiment, the lid assembly 50 includes a machine lid 30 and a cup lid 25. The cup lid 25 covers the blending cup 21 of the food processor 100, and the machine lid 30 covers the cup lid 25. The assembly hole 5021 includes a first assembly hole 5022 penetrating through the machine lid 30 and a second assembly hole 5023 penetrating through the cup lid 25. The bottom end of the sealing structure 503 extends beyond the first assembly hole 5022 and is assembled into the second assembly hole 5023. The sealing member 5032 is fitted and sealed against the inner wall of the second assembly hole 5023. The assembly part 500 is disposed on the cup lid 25.

[0078] The machine cover 30 and the cup cover 25 are detachably arranged, which is convenient for processing and forming. The cup cover 25 can be removed for separate cleaning, which is not only convenient for cleaning but also can be washed more thoroughly. After the food ingredients are prepared, when the mixing cup 21 is removed from the base 11, the cup cover 25 still blocks the food ingredients, which can prevent the food ingredients from spilling and also prevent burns caused by the heat of the food ingredients. The cup cover 25 can also block dust, which is more user-friendly. The bottom end of the sealing structure 503 extends beyond the first assembly hole 5022 and is assembled into the second assembly hole 5023. The sealing member 5032 is in contact with and seals the inner wall of the second assembly hole 5023. The sealing structure 503 is integrally formed as a single piece, and the sealing effect is better. In another embodiment, the sealing structure 503 can also be provided in a two-piece form, with the upper half assembled in the first assembly hole 5022 and the lower half assembled in the second assembly hole 5023. When the machine cover 30 is closed, the upper half and the lower half are in contact with and seal each other.

[0079] In another embodiment, the machine cover 30 and the cup cover 25 are integrally arranged, which makes the structure simpler and can also reduce the operation steps when making food ingredients.

[0080] In one embodiment, the sealing structure 503 is assembled into the assembly hole 5021 from top to bottom. When assembling and disassembling the sealing structure 503, there is no need to open or remove the cover assembly 50, which is convenient for assembling and disassembling the sealing structure 503 and improves the convenience when cleaning the sealing structure 503. In another embodiment, the sealing structure 503 is assembled into the assembly hole 5021 from bottom to top.

[0081] In one embodiment, the bottom of the sealing structure 503 is narrowed. When the sealing structure 503 is assembled into the assembly hole 5021 from top to bottom, the bottom of the sealing structure 503 is convenient to be inserted into the assembly hole 5021, and it is easier to assemble the sealing structure 503.

[0082] See Figures 16 to 17 , in one embodiment, the sealing structure 503 includes a sealing member 5032 and a support member 5033 located inside the sealing member 5032. The hardness of the support member 5033 is greater than that of the sealing member 5032, and the sealing member 5032 is in contact with and seals the inner wall of the assembly hole 5021.

[0083] The sealing structure 503 provides an exhaust function through the exhaust channel 5031 and provides a sealing function by the sealing member 5032 being in contact with the inner wall of the assembly hole 5021, so that the sealing structure 503 has both exhaust and sealing functions. The setting of the support member 5033 increases the hardness of the sealing structure 503, making the sealing structure 503 easier to assemble and preventing deformation, so as to reduce the probability of blockage. The structure of the sealing structure 503 is relatively simple, which makes the structure of the food processor 100 correspondingly simple. At the same time, the sealing structure 503 is also easier to clean.

[0084] The seal 5032 can be made of silica gel, rubber, fluororubber, etc. The support 5033 can be made of plastic, etc.

[0085] In one embodiment, a first sealing lip 5034 and a second sealing lip 5035 are provided on the outer sidewall of the seal 5032. The second assembly hole 5023 is funnel-shaped. The first sealing lip 5034 is located above the second sealing lip 5035 and its free end extends beyond the free end of the second sealing lip 5035. Both the first sealing lip 5034 and the second sealing lip 5035 are in sealing contact with the inner wall of the second assembly hole 5023. When the first sealing lip 5034 and the second sealing lip 5035 are in sealing contact with the inner wall of the second assembly hole 5023, elastic deformation will occur to improve the sealing effect.

[0086] In one embodiment, a first length that the first sealing lip 5034 extends in a direction away from the exhaust passage 5031 is greater than a second length that the second sealing lip 5035 extends in a direction away from the exhaust passage 5031, so that the free end of the first sealing lip 5034 extends beyond the free end of the second sealing lip 5035.

[0087] The second assembly hole 5023 is funnel-shaped. When the machine cover 30 is closed, it is convenient for the bottom of the sealing structure 503 to be inserted into the second assembly hole 5023, so as to avoid the problem of sealing failure caused by improper assembly; the setting of the first sealing lip 5034 and the second sealing lip 5035 provides two seals to ensure the sealing effect.

[0088] In one embodiment, a rib 5036 is provided on the outer sidewall of the seal 5032 to abut against the inner wall of the first assembly hole 5022, increasing the stability of the sealing structure 503, preventing shaking, so as not to affect the sealing effect.

[0089] In one embodiment, the rib 5036 extends in the vertical direction to increase the contact area with the inner wall of the first assembly hole 5022, and the sealing structure 503 is more stable. In another embodiment, the rib 5036 can also be arranged horizontally or obliquely.

[0090] In one embodiment, an inclined guiding surface 50361 is provided at the bottom end of the rib 5036 to guide the sealing structure 503 into the assembly hole 5021, making it easier to assemble the sealing structure 503.

[0091] See Figures 18 to 22 , in one embodiment, the seal 5032 includes an upper resisting portion 5037. The upper resisting portion 5037 protrudes from the top of the cover main body 502 and abuts against the top of the cover main body 502. The upper resisting portion 5037 can prevent the sealing structure 503 from being assembled improperly; it can also be grasped to facilitate the removal of the sealing structure 503.

[0092] In one embodiment, the upper abutment portion 5037 is configured as an annular shape along the circumferential direction of the seal 5032. In another embodiment, the upper abutment portion 5037 may also extend to one side from the seal 5032 in a sheet-like shape, and one or more may be provided.

[0093] In one embodiment, the seal 5032 includes a first lower abutment 5038, and the cover 30 includes a second lower abutment 372. The first lower abutment 5038 is located below the second lower abutment 372 and abuts against the second lower abutment 372, which can prevent the bottom of the sealing structure 503 from tilting up; it can also prevent the sealing structure 503 from being pushed upward by the cup lid 25 and detaching from the cover 30 when the cover 30 is closed.

[0094] The upper abutment 5037, the protruding rib 5036, the first lower abutment 5038, the first sealing lip 5034, and the second sealing lip 5035 are arranged sequentially from top to bottom along the height direction of the sealing structure 503.

[0095] In one embodiment, the first lower abutment portion 5038 extends in a ring shape along the circumferential direction of the seal 5032. In another embodiment, at least two disconnected first lower abutment portions 5038 may also be provided along the circumferential direction of the seal 5032.

[0096] In one embodiment, the second lower abutment 372 may also be annular.

[0097] In one embodiment, the cover 30 includes a cover housing 37 and a panel 36. The cover housing 37 includes a surrounding rib 373 located below the panel. The first assembly hole 5022 includes a third assembly hole 5024 formed by the surrounding rib 373 and a fourth assembly hole 5025 disposed on the panel 36. The cover housing 37 and the panel 36 are separately configured, which facilitates processing and molding.

[0098] The surrounding reinforcement 373 increases the stability of the sealing structure 503. In one embodiment, the protruding rib 5036 abuts against the surrounding reinforcement 373.

[0099] In one embodiment, the upper abutment portion 5037 protrudes from the top of the panel 36 and abuts against the top of the panel 36.

[0100] In one embodiment, the reinforcing rib 373 abuts against the panel 36 to prevent the panel 36 from being suspended.

[0101] In one embodiment, the seal 5032 includes a limiting hole 50321, and the support 5033 is located inside the limiting hole 50321. The support 5033 forms part of the exhaust channel 5031, which is convenient for processing and forming. The support 5033 can also be detached from the seal 5032 for easy replacement, thereby reducing maintenance costs.

[0102] In another embodiment, the support member 5033 may be integrally provided with the seal member 5032. In another embodiment, the support member 5033 may also be located inside the side wall of the seal member 5032.

[0103] In one embodiment, the seal member 5032 includes an upper boss 50322 and a lower boss 50323. The upper boss 50322 is located above the support member 5033, and the lower boss 50323 is located below the support member 5033 to increase the stability of the support member 5033 and prevent the support member 5033 from falling off.

[0104] See Figures 14 to 15 , in one embodiment, the cooking machine 100 includes a machine base 10 and a mixing cup 21. The machine base 10 includes a base 11 and a support base 12 extending upward from the base 11. The cover assembly 50 is connected to the support base 12, for example, rotatably connected or detachably connected or integrally formed. The cover assembly 50 covers the mixing cup 21.

[0105] A power supply component 13 is provided in the support base 12, and a control component 31 electrically connected to the power supply component 13 is provided in the cover assembly 50, which can effectively reduce the height of the cooking machine 100, making it more compact and delicate. In this way, the vibration generated by the cooking machine 100 during operation can be reduced, and the occupied space is smaller.
