Description

Technical Field

[0001] This utility model belongs to the field of food processing machines, and in particular relates to a safe food processing machine. Background Technology

[0002] Existing food processors generally consist of a main unit, a cup body mounted on the main unit, a pulverizing blade inside the cup body, a lid on top of the cup body, and a vent plug on the lid. When the heating device heats the liquid inside the cup, the generated steam is released through the vent plug, maintaining a balance of air pressure inside and outside the cup body. When using a food processor to process various liquids or beverages, users need to add materials in stages to prevent the full release of nutrients and to avoid damage from prolonged processing. The lid of the food processor is usually kept closed during operation. Once the lid is opened, the motor and heating device of the food processor stop working to ensure user safety.

[0003] Based on the user's need to add materials during food processing without interrupting the process by opening the lid and cutting off the power, existing technologies, such as food processors with patent numbers CN201821841039.6 and CN201910489418.6, have a through hole in the cup lid and a feeding cover at the through hole. When materials need to be added during processing, simply open the feeding cover and add the materials through the through hole. After adding the materials, the feeding cover is installed into the opening. This satisfies the need for adding materials during processing and also allows for timely discharge of steam from the cup during heating by setting an exhaust gap at the connection between the feeding cover and the cup lid, or by setting an exhaust gap on the feeding cover that communicates with the cup body. Patent number CN201920441468.2 also discloses a buffer chamber set at the upper end of the insertion part of the feeding cover, which further reduces processing noise while achieving exhaust, and the feeding cover can be removed after use so that the buffer chamber can be cleaned. The patent with patent number CN201621093386.6 also discloses a method of preventing slurry from splashing or overflowing by setting baffles between the feeding cap and the cup cap.

[0004] Currently, users have increasing demands for multifunctional processing of diverse ingredients and higher quality finished products, which places higher requirements on food processing machines. Users in high-altitude areas, in particular, have higher requirements for the milk tea making function of food processing machines. The tea ingredients used to make milk tea typically include brick tea and oils extracted from yak or goat milk. This leads to excessive oxidation of the tea ingredients during processing due to excessive contact with air, and the greater thermal inertia of the slurry makes it more prone to overflow. Therefore, there are higher requirements for thorough and dynamic safe overflow prevention in the slurry rich in brick tea substances and oil components. How to achieve thorough and safe processing of tea ingredients in the milk tea processing process is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this invention is to address the problem that when a food processor is used to make milk tea, the steam pressure generated by heating the liquid inside the cup is too high, causing the oily liquid to easily overflow or splash from the cup lid.

[0006] To solve the above-mentioned technical problems, this utility model provides a food processing machine, including a cup assembly comprising a cup body and a cup lid. A stirring device driven by a motor is provided inside the cup body. The cup lid covers the mouth of the cup body, and a through hole is provided in the middle of the cup lid, extending downwards to form a through mounting cylinder. The cup mouth has a spout that connects the inner cavity of the cup body to the outside. A tea basket assembly is detachably installed inside the mounting cylinder, including an inner lid and a tea basket connected to the inner lid. The tea basket does not contact the mounting cylinder. An annular recessed platform is provided at the upper end of the mounting cylinder, and an annular overlapping surface is provided on the inner lid, sealingly overlapping the recessed platform. An annular step is formed radially inwards at the lower part of the mounting cylinder. The inner diameter of the annular step is smaller than the inner diameter of the recessed platform and the outer diameter of the flange. A transverse connecting channel is provided between the lower end face of the flange and the upper end face of the annular step. A first buffer gap is provided between the inner lid sidewall below the overlapping surface and the mounting cylinder sidewall, and the connecting channel connects the inner cavity of the cup body to the first buffer gap.

[0007] Furthermore, the mounting cylinder extends downward at the annular step to form an annular step sidewall, and a second buffer gap is provided between the annular step sidewall and the sidewall of the tea basket. The first buffer gap is connected to the second buffer gap through the connecting channel.

[0008] Furthermore, a sealing element is provided between the inner cover and the upper end of the mounting cylinder. The sealing element includes a first sealing rib, which is located between the overlapping surface and the recessed platform and seals the upper end of the first buffer gap.

[0009] Furthermore, the inner cover has an annular boss extending outward in a circumferential direction on its side wall, and the lower end face of the annular boss forms the overlapping surface.

[0010] Furthermore, a protrusion is provided below the flange of the tea basket, and a swivel is provided on the inner cover. The protrusion and the swivel cooperate to screw the tea basket onto the inner cover. The swivel includes a first protrusion with a horizontal upper surface and a second protrusion with an inclined upper surface. The upper surface of the second protrusion is gradually inclined upward along the screwing direction of the tea basket, and a baffle is provided at the end of the second protrusion along the screwing direction.

[0011] Furthermore, the inner cover includes an integrally connected upper cover and a lower cover, one of which is provided with a buckle, and the other is provided with a groove that cooperates with the buckle. The lower cover is installed inside the mounting cylinder, and the upper cover is sealed and closed on the upper port of the lower cover, and the upper cover and the lower cover together form a sealed cavity.

[0012] Furthermore, the bottom wall of the inner cover is provided with a downwardly extending rim, the tea basket is screwed onto the rim, and the flange abuts against the bottom wall of the inner cover.

[0013] Furthermore, the surrounding edge is provided with a sealing ring and a mounting groove for installing the sealing ring, and the sealing rib of the sealing ring abuts against the inner side wall of the tea basket.

[0014] Furthermore, the cup lid is provided with an insertion part that extends into the inner cavity of the cup body. The insertion part is located on the outside of the mounting cylinder. The insertion part is provided with a cup lid sealing ring. Above the cup lid sealing ring, the insertion part is also provided with an inner cup spout that is radially corresponding to and communicates with the cup spout. The sealing rib of the cup lid sealing ring abuts against the inner side wall of the cup body. The insertion part is provided with an air pressure balancing part, which is located above the cup lid sealing ring.

[0015] Furthermore, the inner wall of the cup is provided with an inwardly protruding bulge, the insertion part of the cup lid is provided with a buckle that engages and limits the engagement with the bulge, and the air pressure balance part is located above or below the buckle.

[0016] Furthermore, the sealing element includes a second sealing rib located below the first sealing rib, the second sealing rib abutting against the inner wall of the mounting cylinder; or, the sealing element includes a sealing body, the sealing body being sleeved on the outer wall of the inner cover, the sealing body having the first sealing rib and the second sealing rib disposed below the first sealing rib integrally formed thereon.

[0017] The beneficial effects of this utility model are: 1. The tea basket assembly is detachably installed inside the mounting cylinder of the cup lid, and the tea basket does not contact the mounting cylinder. The upper end of the mounting cylinder has an annular step, allowing the tea basket assembly to seal against the cup lid's support through the overlapping surface on the inner lid. The upper end of the first buffer gap below the overlapping surface is blocked, preventing steam in the cup from passing through the inner lid and the mounting cylinder, and instead allowing it to escape through the spout, maintaining pressure balance between the inner cavity of the cup and the outside. A transverse connecting channel is provided between the lower end face of the tea basket's flange and the upper end face of the annular step. This transverse channel serves to prevent oily slurry from entering the stirring device. Driven upwards, the slurry flows into the first buffer gap. Especially when the stirring device is continuously stirring at high speed, the slurry tends to impact the cup lid upwards. The horizontally arranged connecting channel effectively prevents the slurry from impacting the tea basket assembly and inner lid. If a small amount of slurry enters the connecting channel, it will quickly block the channel. At this time, one end of the buffer gap is sealed by the overlapping surface. The slurry in the blocked connecting channel continues to move under inertia and compresses the air in the buffer gap, effectively preventing more slurry from entering the connecting channel and buffer gap. This avoids the grease-rich slurry from rapidly overflowing between the inner lid and the inner wall of the mounting cylinder. On the other hand, when the steam in the cup moves upwards, the upward pressure is greatly reduced after passing through the buffer gap, which can effectively prevent the steam in the cup from lifting the inner lid and tea basket, fully ensuring the user's safety. The airflow inside the cup cavity can be flexibly compressed or expanded within the first buffer gap through the connecting channel. Based on the exhaust from the spout, the buffer gap effectively adjusts the air pressure in the inner cavity at the inner cover, ensuring reliable installation of the tea basket assembly during processing. The slurry is less likely to overflow from the joint between the inner cover and the mounting cylinder, thus helping to balance and stabilize the air pressure inside the cup cavity.

[0018] 2. The second buffer gap further extends the length of the air gap, providing better buffering for the slurry and steam. The annular stepped sidewall can also effectively limit the tea basket, preventing it from swinging or even falling off when the slurry surges violently. The extended gap, sealed at one end, provides better noise reduction. Furthermore, high-concentration, oily slurry is less likely to seep into the gap and lift the tea basket assembly. After the tea basket and inner lid are screwed together, they can be quickly and easily installed onto the cup lid from top to bottom, making operation convenient and ensuring user safety during processing.

[0019] 3. A sealing element is provided between the inner cover and the mounting cylinder. The first sealing rib seals between the overlapping surface and the recessed platform, effectively blocking the buffer gap and preventing communication between the connecting channel and the buffer gap and the outside. It also acts as a buffer when the tea basket assembly is removed from the cup lid. The sealing element also includes a second sealing rib, located at the upper end of the buffer gap. The sealing element includes a sealing body, preferably with the first and second sealing ribs integrally formed on the sealing body.

[0020] 4. The bottom wall of the inner lid has a surrounding edge, and the inside of the inner lid is a sealed cavity to prevent slurry from seeping in and to make it easier for users to clean after use. The tea basket is screwed onto the surrounding edge of the inner lid by a protrusion, so that the bottom wall of the inner lid covers the upper end of the tea basket. The protrusion and the buckle are connected by the upward-sloping upper surface of the second protrusion, so that the tea basket is tightened more and more on the surrounding edge of the inner lid, so that the folded edge of the tea basket is tightly against the bottom wall of the inner lid. Even if the slurry is impacted and surged by the stirring device during the processing, the tea basket will not shake or make abnormal noise.

[0021] 5. The inner cover includes an upper cover and a lower cover. The upper cover and the lower cover are engaged by snaps and slots, and a sealing ring is provided at the snap contact to further ensure the sealing of the sealing cavity inside the inner cover. This makes it convenient for users to add materials during the process while reducing processing noise.

[0022] 6. The cup lid insertion part is provided with an air pressure balancing part, and the cup lid sealing ring is set below the cup spout to seal the inner cavity of the cup. If the cup is tilted at a large angle when the user pours the syrup, the syrup will completely cover the cup spout at the moment of pouring. The tea basket assembly will then seal and cover the cup lid through hole and the mounting cylinder. The cup lid sealing ring seals the inner cavity of the cup. The air pressure balancing part can effectively introduce external gas into the space inside the insertion part through the gap between the cup lid and the cup mouth, thereby keeping the air pressure inside the cup cavity balanced with the outside, and ensuring smooth pouring.

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 7As shown, this embodiment provides a safe food processor, including a main unit, a cup assembly 100 connected to the main unit, and a tea basket assembly 200 mounted on the cup assembly 100. The cup assembly 100 includes a cup body 101 and a cup lid 102. The cup body 101 is equipped with a stirring device 103 driven by a motor. In this embodiment, the motor is preferably located inside the main unit. The stirring device includes a pulverizing blade. The cup lid 102 covers the cup opening 112 of the cup body, and the cup lid 102 has a through hole 105 in the middle. The through hole extends downward to form a through mounting cylinder 106, and the cup mouth 112 is provided with a spout 104 that connects the inner cavity 111 of the cup to the outside. The tea basket assembly 200 is detachably installed in the mounting cylinder 106. The tea basket assembly 200 includes an inner cover 201 and a tea basket 204 connected to the inner cover 201. The tea basket is provided with a filter hole. The tea material in the tea basket flows through the filter hole and communicates with the slurry in the inner cavity of the cup. Under the rotation of the stirring device, it is fully and evenly mixed and the nutrients in the tea material are released. The tea basket 204 does not contact the mounting cylinder 106; the upper end of the mounting cylinder 106 is provided with an annular recess 107, and the inner cover 201 is provided with an annular overlapping surface 206, which is sealed and overlapped on the recess 107; preferably, the inner wall of the mounting cylinder 106 of the cup lid is provided with spaced retaining ribs 110, which protrude relative to the inner wall of the mounting cylinder 106 to help limit the inner cover 201 and prevent the entire tea basket assembly 200 from swinging radially within the mounting cylinder 106.

[0034] like Figure 2 and Figure 3As shown, the lower part of the mounting cylinder 106 extends radially inward to form an annular step 108. The inner diameter of the annular step 108 is smaller than the inner diameter of the recessed platform 107 and the outer diameter of the flange 205. A transverse connecting channel 300 is provided between the lower end face of the flange 205 and the upper end face of the annular step 108. A first buffer gap 301 is provided between the inner cover sidewall below the overlapping surface 206 and the mounting cylinder sidewall. The connecting channel 300 connects the inner cavity 111 of the cup body 101 used for food processing with the first buffer gap 301. The first buffer gap 301 is preferably a uniform gap. When there is slurry rising, the air filled in the gap prevents the slurry from entering the buffer gap due to the obstruction of the connecting channel 300. Moreover, the gas in the buffer gap is compressed by the slurry that partially enters the transverse channel, which plays a buffering role and prevents the slurry or steam from pushing the inner cover 201 and the tea basket upward out of the cup lid. As a preferred range, the gap of the connecting channel is 0.5mm to 10mm, with a preferred value of 1.5mm, to ensure accurate installation of the tea basket and prevent contact with the cup lid mounting cylinder 106. Airflow can flexibly compress or expand within the first buffer gap 301 through the connecting channel 300. Based on the exhaust from the spout 104, the buffer gap effectively adjusts the air pressure at the inner cover 201 within the inner cavity 111, ensuring reliable installation of the tea basket assembly 200 during processing. This prevents slurry from overflowing from the junction of the inner cover 201 and the mounting cylinder 106, and maintains a stable and balanced air pressure within the cup's inner cavity 111. It is understood that the first buffer gap can also be set to a variable gap value, which can further reduce noise while meeting buffering pressure requirements.

[0035] like Figure 3As shown, the tea basket assembly 200 is detachably installed from top to bottom into the mounting cylinder 106 of the cup lid. The upper end of the mounting cylinder 106 is provided with an annular step, allowing the tea basket assembly 200 to seal against the cup lid's support through the overlapping surface 206 on the inner cover 201. The upper end of the first buffer gap 301 located below the overlapping surface 206 is blocked, preventing steam in the cup from passing through the inner cover 201 and the mounting cylinder 106. Instead, steam is discharged outward through the spout 104, which communicates with the outside, maintaining pressure balance between the inner cavity 111 of the cup and the outside. A transverse connecting channel 300 is provided between the lower end face of the tea basket flange 205 and the upper end face of the annular step 108. The transverse connecting channel 300 serves to block oily slurries. Driven by the stirring device, the slurry flows upward into the first buffer gap 301. Especially when the stirring device is continuously stirring at high speed, the slurry tends to impact the cup lid upward. The horizontally arranged connecting channel 300 can effectively prevent the slurry from impacting the tea basket assembly 200 and the inner lid 201. If a small amount of slurry enters the connecting channel 300, it will quickly block the connecting channel 300. At this time, one end of the buffer gap is sealed by the overlapping surface 206. The slurry in the blocked connecting channel 300 continues to move under inertia and compresses the air in the buffer gap, which can effectively prevent more slurry from entering the connecting channel 300 and the buffer gap, thereby avoiding the grease-rich slurry from rapidly overflowing between the inner lid 201 and the inner wall of the mounting cylinder. On the other hand, when the steam in the cup moves upward, the upward pressure is greatly reduced after passing through the buffer gap, which can effectively prevent the steam in the cup from lifting the inner lid 201 and the tea basket, fully ensuring the user's safety.

[0036] like Figure 4 and Figure 5 As shown, the mounting cylinder 106 extends downward at the annular step 108 to form an annular step sidewall 109. A second buffer gap 302 is provided between the annular step sidewall 109 and the sidewall of the tea basket. The first buffer gap 301 is connected to the second buffer gap 302 through the connecting channel 300. The setting of the second buffer gap 302 further extends the length of the air gap, which has a better buffering effect on the slurry and steam. Moreover, the annular step sidewall 109 can also effectively limit the tea basket. When the slurry surges violently, it can effectively prevent the tea basket from swinging or even falling off. The extended gap with one end sealed can play a better noise reduction role. Moreover, the high concentration of oily slurry is not easy to seep into the gap and lift the tea basket assembly 200. After the tea basket and the inner cover 201 are screwed together, they can be quickly and conveniently installed on the cup lid from top to bottom. The operation is convenient and can fully ensure the user's safety during the processing.

[0037] A sealing element 303 is provided between the inner cover 201 and the upper end of the mounting cylinder 106. The sealing element 303 includes a first sealing rib 304. The first sealing rib 304 is located between the overlapping surface 206 and the recessed platform 107 and blocks the upper end of the first buffer gap 301. On the one hand, it effectively blocks the buffer gap, so that the connecting channel 300 and the buffer gap are not connected to the outside. When the crusher rotates at high speed, the first sealing rib 304 can effectively reduce vibration and prevent vibration noise from being transmitted to the outside. On the other hand, it plays a buffering role when the tea basket assembly 200 is disassembled from the cup lid. The sealing element 303 further includes a second sealing rib 305, disposed at the upper end of the buffer gap. Preferably, the sealing element 303 includes a sealing body 306. The sealing element 303 includes a first sealing rib 304 integrally disposed on the sealing body 306 and a second sealing rib 305 located below the first sealing rib 304. The second sealing rib 305 abuts against the inner wall of the mounting cylinder. The sealing body 306 is sleeved on the outer wall of the inner cover 201. The first sealing rib 304 and the second sealing rib 305 are integrally formed on the sealing body 306. In this embodiment, the sealing element is further optimized. The sealing body 306 is provided with two rings of second sealing ribs 305. The second sealing rib 305 located in the middle position extends outward for a longer length than the lowermost second sealing rib 305. The second sealing rib 305 in the middle position is used to seal with the inner wall of the cup lid mounting cylinder 106 to prevent tilting and falling off. Moreover, this arrangement can further ensure the sealing performance of the upper end of the buffer gap, making it less likely to be pushed up by slurry or steam, and less likely to be conductive to the outside. The second sealing rib 305, located at the bottom, further optimizes the feel of assembling and disassembling the tea basket assembly 200 and prevents it from falling off during handling and processing. Understandably, the first sealing rib 304 and the second sealing rib 305 can also be separately installed between the inner cover 201 and the mounting cylinder 106.

[0038] In this embodiment, as Figure 6As shown, the inner cover 201 has an annular boss 207 extending outward in a circumferential direction on its side wall, and the lower end face of the annular boss 207 forms the overlapping surface 206. The annular boss 207 sinks into the recessed platform 107 to radially limit the tea basket assembly 200, and the upper end face of the recessed platform 107 cooperates with the overlapping surface 206 of the annular boss 207 to axially support the tea basket assembly 200. A protrusion 208 is provided below the flange 205 of the tea basket, and the inner cover has a snap fastener 209. The protrusion and the snap fastener 209 cooperate to screw the tea basket onto the inner cover 201. Specifically, the swivel buckle 209 includes a first protrusion 210 horizontally positioned on its upper surface and a second protrusion 211 inclined on its upper surface. The upper surface of the second protrusion 211 gradually slopes upward along the screwing direction of the tea basket. A baffle 212 is provided at the end of the second protrusion 211 along the screwing direction. The baffle 212 is vertically positioned and integrally connected to the end of the second protrusion 211. The upper surface of the second protrusion 211 is also provided with an anti-retraction structure 213, which is a protrusion that can circumferentially limit the movement of the tea basket and prevent it from screwing off the inner cover 201 when the slurry is in a state of violent movement. The bottom wall of the inner cover 201 is provided with a downwardly extending rim 217. The swivel buckle is provided on the rim. A rim sealing ring 220 and an installation groove 219 for installing the sealing ring are fitted below the swivel buckle 209 on the rim. The tea basket is screwed onto the rim, and the flange 205 abuts against the bottom wall of the inner cover 201. Specifically, the inner cover 201 has a sealed cavity 216 inside, which prevents slurry from seeping in and makes it easier for users to clean after use. The tea basket is screwed onto the edge of the inner cover 201 by a protrusion, so that the bottom wall of the inner cover 201 covers the upper end of the tea basket. The protrusion and the buckle 209 are connected by the upward-sloping upper surface of the second protrusion 211, so that the tea basket is screwed tighter and tighter on the edge of the inner cover 201, so that the flange 205 of the tea basket is tightly abutted against the bottom wall of the inner cover 201. Even if the slurry is violently impacted and surged under the action of the stirring device during the processing, the inner cover 201 and the tea basket will not shake or make any abnormal noise.

[0039] like Figure 7As shown, the cup lid includes a cup lid body and an annular insertion part 113 formed by the downward extension of the bottom wall of the cup lid body, which is inserted into the cup mouth. The cup lid also has a cup lid rim on the outside of the insertion part, which overlaps with the cup mouth. The insertion part is provided with a pressure balancing part 114, which is located above the cup lid sealing ring. In this embodiment, it is preferred to have a pressure balancing hole that penetrates the side wall of the insertion part, and preferably one such hole. The lower end of the insertion part 113 is also provided with an annular insertion part mounting groove 116 and a cup lid sealing ring 115 installed in the insertion part mounting groove. The sealing rib of the cup lid sealing ring abuts against the inner side wall of the cup body to prevent the slurry from overflowing from the cup mouth. The cup lid sealing ring is located below the spout, sealing the inner cavity of the cup. If the cup is tilted at a large angle when pouring the syrup, the syrup will completely cover the spout at the moment of pouring. The tea basket assembly then seals and covers the cup lid through hole and the mounting cylinder. The air pressure balance section can effectively guide the outside air through the gap between the cup lid and the cup mouth into the space inside the insertion part, thereby keeping the air pressure inside the cup cavity balanced with the outside air, and ensuring smooth pouring.

[0040] This embodiment further optimizes the installation structure and air pressure balance part of the cup lid. Specifically, the inner wall of the cup is provided with an inwardly protruding convex 117, and the insertion part of the cup lid is provided with a locking position 118 that screws and limits the convex 117. In this embodiment, the locking position is formed by the outer wall of the insertion part protruding outward. Preferably, the locking position includes an upper locking position 119 and a lower locking position 120. The air pressure balance hole is axially arranged between the upper locking position and the lower locking position. When the convex 117 is screwed and installed between the upper locking position and the lower locking position, the gap between the outer surface of the convex 117 and the air pressure balance hole is set. The insertion part, the cup lid sealing ring, the cup body sidewall, the cup lid edge 125, and the cup lid body 124 together form an annular cavity 126. The insertion part, located above the cup lid sealing ring, also has an inner cup spout 127 that radially corresponds to and communicates with the cup spout. Preferably, the inner cup spout is a closed liquid flow notch located on the sidewall of the insertion part. Under normal processing conditions, the annular cavity is connected to the external atmospheric pressure through the inner cup spout 127 and the cup spout 104, and also through the gap formed by the overlap of the cup lid edge 125 and the cup mouth 112. During processing, the annular cavity is connected to the inner cavity 111 of the cup through the cup spout 104 and the pressure balance part 114, ensuring a balanced communication between the inner cavity of the cup and the outside air pressure. After processing, in the initial stage of safe pouring without opening the lid, the cup body is tilted during pouring. A large amount of slurry instantly blocks the spout 104 and the inner spout 127, preventing outside air from entering the inner cavity of the cup. At this time, outside air first enters the annular cavity 126 through the gap between the lid edge 125 and the cup mouth 112, and then enters the inner cavity 111 through the air pressure balance part 114 from the annular cavity 126. This achieves communication and balance between the inner cavity 111 of the cup and the external atmospheric pressure, ensuring smooth pouring. This avoids the formation of negative pressure in the inner cavity of the cup, which would prevent pouring without opening the lid. It is understood that the fastener is integrally formed on the insertion part. After the cup lid is screwed in, the fastener is located below the protrusion, and the flat pressure balance part is located above the integral fastener, radially corresponding to the protrusion. The protrusion can effectively prevent the cup lid from axially detaching upwards and block the slurry from entering the air pressure balance part.

[0041] The cup structure is further optimized. The cup body 101 includes a plastic outer shell 123 and a stainless steel inner liner 122. Two protrusions 117 are formed by a partial inward protrusion of the side wall of the inner liner. After the lid 102 is installed, the upper latch is located above the protrusion, and the lower latch is located below it. The protrusion and latch cooperate to axially limit the lid. Preferably, both the upper and lower latches have clearance grooves 121 to avoid the pressure balance hole, ensuring smooth airflow through the pressure balance hole. The upper and lower latches also prevent slurry from blocking the pressure balance hole. The inner liner has a cup body flange at the rim, which covers the upper end of the outer shell, creating a flat upper surface that rigidly overlaps with the lid, allowing airflow through the overlapping gap.

[0042] The inner cover 201 includes an integrally connected upper cover 202 and lower cover 203. The upper cover 202 and lower cover 203 are engaged by a snap-fit ​​214 and a slot 215, and a sealing ring 218 is provided at the snap-fit ​​point. After the upper cover 202 and lower cover 203 are engaged and installed, the sealing ring is clamped and fixed to prevent liquid from entering the sealing cavity 216 from the contact gap between the upper cover 202 and lower cover 203, further ensuring the sealing performance of the sealing cavity 216 inside the inner cover. This facilitates material addition during the process and reduces processing noise. Specifically, one of the upper cover 202 and lower cover 203 is provided with a snap-fit ​​214, and the other is provided with a slot 215 that mates with the snap-fit ​​214. The lower cover 203 is installed inside the mounting cylinder 106, and the upper cover 202 seals and covers the upper port of the lower cover 203. The upper cover 202 and lower cover 203 together form the sealing cavity 216. The inner cover 201 has a sealing ring 220 and an annular mounting groove 219 for mounting the sealing ring 220. The sealing ring 220 has a T-shaped cross-section, and its sealing ribs abut against the inner wall of the tea basket, limiting the space between the side wall below the tea basket flange 205 and the edge of the inner cover 201, preventing tea from overflowing from the tea basket flange 205. Especially when the tea basket assembly 200 is removed from the cup lid and the user places it upside down on a horizontal table, the sealing ring 220 effectively prevents residual water or liquid from seeping out, avoiding soiling the table.
