Description

Technical Field

[0001] The present application belongs to the technical field of water cups, and specifically relates to a cup cover assembly and a thermos cup. Background Art

[0002] Most of the thermos cups on the market are composed of two parts: an inner plug and a cup body. The cup body is used to hold liquid, and the inner plug is used to seal the cup body and control the opening and closing of the water outlet of the cup body.

[0003] The prior art discloses a push-type inner plug, which includes an upper cover assembly, a water sealing assembly and a drinking mouth piece. The drinking mouth piece is provided with a water outlet for water to flow out and a vent hole for gas to flow; the upper cover assembly is hinged to the drinking mouth piece; the water sealing assembly includes a sealing block, which is connected to the upper cover assembly. When the upper cover assembly covers the water outlet, the sealing block abuts against the wall of the sealed water outlet and the wall of the vent hole to prevent water from flowing out.

[0004] However, on the one hand, the function of the vent hole is mainly to achieve ventilation during the drinking process, and when the drinking mouth is sealed by the water sealing assembly, the vent hole is also sealed by the sealing block. Therefore, when the pressure in the cup is less than the atmospheric pressure, the sealing block will be sucked by the water outlet and the vent hole at the same time under the influence of the air pressure, resulting in the upper cover assembly being unable to be opened. At this time, forcibly opening the cover may easily cause damage to the sealing block on the one hand, and may easily cause the sealing block to fall off from the upper cover on the other hand, thereby facing problems such as being more difficult to remove and requiring reinstallation of the sealing block; on the other hand, the vent hole and the sealing block of the above-mentioned push-type inner plug are arranged near the upper cover and the drinking mouth. At the rotating connection of the parts, when the upper cover has a tendency to rotate and open during the opening process, the setting positions of the sealing block and the vent are such that the sealing block will only be separated from the vent when the upper cover is rotated and opened to the second half of the position, resulting in the inability to achieve pressure relief within the initial time period, and the suction cup phenomenon cannot be eliminated, thereby hindering the opening of the cover; furthermore, the sealing block needs to be provided with a spherical protrusion for blocking the water outlet and a sealing block for opening or closing the vent. The structure of the water sealing plug is complicated, and the processing and manufacturing costs are increased. In addition, during the assembly process, higher precision requirements are placed on the alignment relationship between the sealing block and the vent. Utility Model Content

[0010] The upper cover is provided with a through hole for the pressure relief component to pass through, and a sealing component is disposed on the outer sleeve of the pressure relief component; the sealing component can abut and seal with the inner wall of the through hole, and deform under the action of external atmospheric pressure to form an air intake gap between the inner wall of the through hole.

[0011] The sealing member includes a main body portion installed on the pressure relief member, and a sealing lip edge connected to the main body portion and extending along the circumference of the main body portion, and the sealing lip edge can abut against the inner wall of the through hole for sealing.

[0012] The upper cover is provided with a through hole for the pressure relief member to pass through, the upper cover is provided with a stopper, and the pressure relief member is provided with a limiting portion. At the pressure relief position, the limiting portion abuts against the stopper to limit the downward displacement of the pressure relief member.

[0013] The cup cover assembly also includes a locking member, which is movably arranged on the upper cover to have a locking position locked with the lower cover and an unlocking position unlocked with the lower cover; the operating member includes an operating part and an extrusion part connected to the operating part, and when the operating part is triggered, it drives the pressure relief member to switch from the closed position to the pressure relief position, and simultaneously drives the extrusion part to push the locking member to move so that the locking member switches from the locked position to the unlocking position.

[0014] The upper cover is provided with an activity space adapted to the operating portion, and the operating portion is pressed and triggered to drive the pressure relief member to move up and down, so that the pressure relief member is switched from the closed position to the pressure relief position.

[0015] The extrusion part is rotatably connected to the upper cover, and a protruding ejection block is provided on a side of the extrusion part facing the locking member.

[0016] The cup cover assembly further comprises an elastic member, the top end of the elastic member abuts against the operating portion, the bottom end of the elastic member abuts against the pressure relief member, and the operating portion drives the pressure relief member to move through the elastic member.

[0017] A thermos cup comprises a cup body and a cup cover assembly arranged at the cup mouth of the cup body, wherein the cup cover assembly is the cup cover assembly as described above, the lower cover is installed at the cup mouth, and when the pressure relief member is in the pressure relief position, the space in the cup body is connected to the external airflow through the pressure relief hole.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0019] 1. The sealing plug in the present application is provided with a pressure relief hole, and the upper cover is provided with an operating member and a pressure relief member linked to the operating member. The operating member can be used to drive the pressure relief member to move along the pressure relief hole to switch from a closed position for closing the pressure relief hole to a pressure relief position for opening the pressure relief hole, thereby achieving air pressure balance inside and outside the cup body, avoiding the cup suction phenomenon of the sealing plug, and facilitating quick opening of the cover.

[0020] First, a pressure relief hole is set on the sealing plug. When the pressure relief hole is opened, outside air can enter the cup body from the pressure relief hole and the water outlet to achieve air pressure balance inside and outside the cup body. Compared with the prior art, this application does not need to open a separate channel for pressure relief on the lower cover. The water outlet plays the role of both the drinking water channel and the pressure relief channel, thereby simplifying the structural design of the lower cover. Compared with the size of the vent hole in the prior art, the size of the water outlet in this application is significantly larger than the vent hole. In actual application, the water outlet in this application will not be easily blocked by debris, thereby ensuring the smooth flow of the pressure relief channel at the water outlet, providing a guarantee for the smooth pressure relief.

[0021] Secondly, the operating part and the pressure relief part are linked. When the operating part is triggered, the pressure relief part can be driven to move, so that the pressure relief part can be switched from the closed position to the pressure relief position. When the pressure relief part is in the pressure relief position, the pressure relief hole is opened, and the external gas enters the cup body through the pressure relief hole and the water outlet to eliminate the pressure difference between the inside and outside of the cup body and open the lid. Therefore, the linkage between the operating part and the pressure relief part in this application improves the timeliness of the response and realizes rapid pressure relief, thus laying the foundation for rapid lid opening.

[0022] 2. As a preferred embodiment of the present application, the pressure relief member is provided with a connected blocking section and a pressure relief section along its axial direction. When the pressure relief member is in the closed position, the blocking section and the pressure relief hole are interference-fitted to close the pressure relief hole, thereby preventing the water in the cup body from overflowing through the pressure relief hole during the use of the thermos cup, and also preventing external impurities from entering the pressure relief hole and blocking the pressure relief channel, thereby ensuring the smoothness of the pressure relief channel. When the pressure relief member is in the pressure relief position, the blocking section moves out of the pressure relief hole, and the air inlet and outlet ends of the pressure relief hole are connected through the air gap between the pressure relief section and the inner wall of the pressure relief hole, and the external gas enters the interior of the cup body through the air gap and the water outlet to eliminate the pressure difference between the inside and outside of the cup body, thereby facilitating the opening of the lid. In other words, when the pressure relief member is in the pressure relief position, at least part of the pressure relief section of the pressure relief member is still located inside the pressure relief hole, and the pressure relief member is not completely removed from the pressure relief hole, thereby facilitating the resetting of the pressure relief member and avoiding the phenomenon that the pressure relief member cannot smoothly return to the closed position due to reasons such as alignment.

[0023] 3. As a preferred embodiment of the present application, the upper cover is provided with a through hole for the pressure relief component to pass through, and a sealing component is disposed on the outer sleeve of the pressure relief component. The sealing component can be sealed against the inner wall of the through hole. On the one hand, when the pressure relief component fails to seal the pressure relief hole, the sealing component can be used as a sealing barrier to prevent the water inside the cup body from flowing out to the outside of the cup body through the pressure relief hole, thereby avoiding water leakage. On the other hand, a sealing shield can be formed for the through hole to prevent impurities outside the cup body from entering the pressure relief hole through the through hole and causing blockage of the pressure relief hole. When the pressure relief hole is opened by the pressure relief component, the sealing component can be deformed under the action of the external atmospheric pressure to form an air intake gap with the inner wall of the through hole. The external gas enters the interior of the cup body through the through hole, the pressure relief guide groove, the pressure relief hole and the water outlet. The air pressure inside and outside the cup body is balanced, which facilitates opening the cover.

[0024] 4. As a preferred embodiment of the present application, the upper cover is provided with a stop portion, and the pressure relief member is provided with a limiting portion. When the limiting portion and the stop portion are against each other, the pressure relief member is in a pressure relief position capable of opening the pressure relief hole. Therefore, the stop cooperation between the limiting portion and the stop portion limits the further downward displacement of the pressure relief member, which can give the user an obvious touch prompt that the pressure relief member is in place, has a stronger explicit effect, and improves the user experience.

[0025] 5. As a preferred embodiment of the present application, the operating member includes a connected operating part and an extruding part. When the operating part is triggered, it can drive the pressure relief part to switch from the closed position to the pressure relief position, and simultaneously drive the extruding part to push the locking part to move so that the locking part switches from the locked position to the unlocked position. This embodiment can simultaneously achieve the two actions of pressure relief and unlocking by triggering the operating member. A single trigger can open the cover in one step, which is simple and quick to operate and provides a better user experience. That is, this embodiment achieves pressure relief while opening the cover, which helps to prevent the sealing plug from being sucked.

[0026] Furthermore, the upper cover is provided with an activity space adapted to the operating part, and the operating part is pressed and triggered to drive the pressure relief part to move up and down, so that the pressure relief part switches from the closed position to the pressure relief position. Pressure relief and unlocking are achieved by pressing, without twisting or prying the upper cover open, and can be achieved with one hand, which is easy and convenient to operate. In some specific scenarios, when only one hand can perform related operations, it is convenient for users to operate. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0051] like Figures 1 to 4 As shown, a cup cover assembly includes an upper cover 5 and a lower cover 6 with a water outlet 61, the upper cover 5 is provided with a sealing plug 7, the upper cover 5 is rotatably connected with the lower cover 6 to open or close the water outlet 61 through the sealing plug 7, the sealing plug 7 is provided with a pressure relief hole 71, the upper cover 5 is provided with an operating member 1 and a pressure relief member 2 linked to the operating member 1, the pressure relief member 2 is movably arranged on the upper cover 5 to have a closed position for closing the pressure relief hole 71 and a pressure relief position for opening the pressure relief hole 71, the operating member 1 drives the pressure relief member 2 to move along the pressure relief hole 71, so that the pressure relief member 2 is switched from the closed position to the pressure relief position.

[0052] The sealing plug 7 in the present application is provided with a pressure relief hole 71, and the upper cover 5 is provided with an operating member 1 and a pressure relief member 2 linked with the operating member 1. The operating member 1 can be used to drive the pressure relief member 2 to move along the pressure relief hole 71 to switch from a closed position of closing the pressure relief hole 71 to a pressure relief position of opening the pressure relief hole 71, thereby achieving air pressure balance inside and outside the cup body, avoiding the cup suction phenomenon of the sealing plug 7, and facilitating quick opening of the cover.

[0053] First, a pressure relief hole 71 is provided on the sealing plug 7. When the pressure relief hole 71 is opened, outside air can enter the cup body from the pressure relief hole 71 and the water outlet 61 to achieve pressure balance inside and outside the cup body. Compared with the prior art technology of providing an independent vent hole on the lower cover 6 to achieve pressure relief, the present application does not need to separately provide a channel for achieving pressure relief on the lower cover 6. The water outlet 61 plays the role of both a drinking water channel and a pressure relief channel when drinking water, thereby simplifying the structural design of the lower cover 6. Moreover, compared with the size of the vent hole in the prior art, the size of the water outlet 61 in the present application is significantly larger than the vent hole. In actual application, the water outlet 61 in the present application will not be easily blocked by debris, thereby ensuring the unobstructed pressure relief channel at the water outlet 61 and providing a guarantee for the smooth progress of pressure relief. Furthermore, the pressure relief hole 71 on the sealing plug 7 is closed by the pressure relief component 2 when pressure relief is not needed, which reduces the probability of external impurities entering the pressure relief hole 71, thereby reducing the probability of the pressure relief hole 71 being blocked. It cooperates with the water outlet 61 to ensure the smooth flow of the pressure relief channel.

[0054] Secondly, the operating member 1 and the pressure relief member 2 are linked. When the operating member 1 is triggered, the pressure relief member 2 can be driven to move, so that the pressure relief member 2 can be switched from the closed position to the pressure relief position. When the pressure relief member 2 is in the pressure relief position, the pressure relief hole 71 is opened, and the external gas enters the cup body through the pressure relief hole 71 and the water outlet 61 to eliminate the pressure difference between the inside and outside of the cup body, thereby opening the lid. Therefore, the linkage of the operating member 1 and the pressure relief member 2 in the present application improves the timeliness of the response, realizes rapid pressure relief, and thus lays the foundation for rapid lid opening.

[0055] As a preferred implementation of the present application, Figure 1 and Figure 2 As shown, the upper cover 5 or the lower cover 6 is provided with a rotating shaft 9, and the upper cover 5 is rotatably connected to the lower cover 6 via the rotating shaft 9. A torsion spring is provided on the rotating shaft 9 so that after the upper cover 5 and the lower cover 6 are unlocked, the upper cover 5 can rotate around the rotating shaft 9 under the action of the restoring force of the torsion spring to drive the sealing plug 7 to move and open the water outlet 61.

[0056] The present application does not limit the specific structural form of the pressure relief member 2, and it can adopt any one of the following embodiments:

[0057] Embodiment 1: The pressure relief member 2 is provided with a blocking section 21; in the closed position, the blocking section 21 is interference fit with the pressure relief hole 71 to close the pressure relief hole 71; in the pressure relief position, the pressure relief member 2 moves upward, the pressure relief member 2 as a whole moves out of the pressure relief hole 71, the pressure relief hole 71 is opened, and the pressure relief hole 71 cooperates with the water outlet 61 to form a pressure relief channel.

[0058] Embodiment 2: The pressure relief member 2 is provided with a connected blocking section 21 and a pressure relief section 22 along its axial direction; in the closed position, the blocking section 21 is interference-fitted with the pressure relief hole 71 to close the pressure relief hole 71. In the pressure relief position, the blocking section 21 moves out of the pressure relief hole 71, at least part of the pressure relief section 22 is located in the pressure relief hole 71, and there is an air gap between the pressure relief section 22 and the inner wall of the pressure relief hole 71, and the air inlet and air outlet of the pressure relief hole 71 are connected through the air gap.

[0059] When the pressure relief member 2 is in the closed position, the blocking section 21 and the pressure relief hole 71 are interference-fitted to close the pressure relief hole 71, which prevents the water in the cup body from overflowing through the pressure relief hole 71 during the use of the thermos cup, and also prevents external impurities from entering the pressure relief hole 71 and blocking the pressure relief channel, thereby ensuring the smoothness of the pressure relief channel. When the pressure relief member 2 is in the pressure relief position, the blocking section 21 moves out of the pressure relief hole 71, and the air inlet and outlet ends of the pressure relief hole 71 are connected through the air gap, and the external gas enters the interior of the cup body through the air gap and the water outlet 61 to eliminate the pressure difference between the inside and outside of the cup body, making it convenient to open the lid. In other words, when the pressure relief member 2 is in the pressure relief position, at least part of the pressure relief section 22 of the pressure relief member 2 is still located inside the pressure relief hole 71, and the pressure relief member 2 is not completely removed from the pressure relief hole 71, thereby facilitating the resetting of the pressure relief member 2 and avoiding the phenomenon that the pressure relief member 2 cannot be smoothly restored to the closed position due to reasons such as alignment.

[0060] In the second embodiment, the structure of the pressure relief member 2 can adopt any one of the following embodiments:

[0061] Embodiment 1: The outer diameter of the pressure relief section 22 is smaller than the outer diameter of the blocking section 21 , so that when the pressure relief section 22 cooperates with the pressure relief hole 71 , a clearance fit is formed between the two, thereby forming an air gap between the pressure relief section 22 and the inner wall of the pressure relief hole 71 .

[0062] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the outer diameter of the blocking section 21 is substantially the same as the outer diameter of the pressure relief section 22. The pressure relief section 22 is provided with a pressure relief guide groove 23 extending along its axial direction. Preferably, the pressure relief guide groove 23 is formed to be recessed inwardly compared to the rest of the pressure relief section 22, so that when the pressure relief section 22 cooperates with the pressure relief hole 71, the pressure relief guide groove 23 constitutes the air gap, and the air inlet and outlet ends of the pressure relief hole 71 are connected through the pressure relief guide groove 23. Furthermore, in the pressure relief position, a portion of the end of the pressure relief section 22 connected to the blocking section 21 is moved out to the outside of the pressure relief hole 71, so that a portion of the pressure relief guide groove 23 is exposed to the pressure relief hole 71, so that the external gas can flow smoothly through the pressure relief hole 71.

[0063] In this embodiment 2, the so-called outer diameter of the sealing section 21 and the outer diameter of the pressure relief section 22 are basically the same, which means that the outer diameter of the sealing section 21 and the outer diameter of the pressure relief section 22 are the same or approximately the same. Slight differences in the outer diameters of the two due to processing errors and the like also fall within the scope of protection of this application.

[0064] As a preferred example of this embodiment 2, Figure 6 As shown, the pressure relief section 22 is provided with a plurality of pressure relief guide grooves 23 at intervals along its circumference. Such a configuration can increase the flow path of the gas, improve the pressure relief efficiency, and thus help to achieve rapid cover opening.

[0065] As a preferred implementation of the present application, Figure 1 and Figure 2 As shown, the upper cover 5 is provided with a through hole 521 for the pressure relief member 2 to pass through, and a sealing member 4 is disposed on the outer sleeve of the pressure relief member 2; the sealing member 4 can abut against the inner wall of the through hole 521 for sealing, and deform under the action of the external atmospheric pressure to form an air intake gap with the inner wall of the through hole 521. The sealing member 4 can abut against the inner wall of the through hole 521 for sealing. On the one hand, when the pressure relief member 2 fails to seal the pressure relief hole 71, the sealing member 4 can be used as a sealing barrier to prevent the water inside the cup body from flowing out to the outside of the cup body through the pressure relief hole 71, thereby avoiding the occurrence of water leakage. On the other hand, the through hole 521 can be sealed to prevent impurities outside the cup body from entering the pressure relief hole 71 through the through hole 521 and causing the pressure relief hole 71 to be blocked. When the pressure relief hole 71 is opened by the pressure relief component 2, the sealing component 4 can be deformed under the action of the external atmospheric pressure to form an air intake gap between the sealing component 4 and the inner wall of the through hole 521. The external gas enters the interior of the cup body through the through hole 521, the pressure relief groove 23, the pressure relief hole 71 and the water outlet 61. The air pressure inside and outside the cup body is balanced, making it convenient to open the lid.

[0066] As a preferred embodiment of this implementation, Figure 1 and Figure 2 As shown, the pressure relief member 2 is provided with a positioning groove for installing the seal 4. The seal 4 is assembled in the positioning groove to prevent the seal 4 from moving along the axial direction of the pressure relief member 2 during the movement of the pressure relief member 2, thereby ensuring the installation position of the seal 4 on the pressure relief member 2.

[0067] As a preferred embodiment of this implementation, Figure 1 and Figure 2As shown, the sealing member 4 includes a main body 41 mounted on the pressure relief member 2, and a sealing lip 42 connected to the main body 41 and extending along the circumference of the main body 41, and the sealing lip 42 can abut and seal against the inner wall of the through hole 521. Specifically, when the pressure relief member 2 is in the pressure relief position, the sealing lip 42 is deformed under the action of the external atmospheric pressure to form an air intake gap between the sealing lip 42 and the inner wall of the through hole 521, and the external gas enters the interior of the cup body through the through hole 521, the air intake gap, the air gap and the water outlet 61 to achieve pressure balance inside and outside the cup body.

[0068] As a preferred implementation of the present application, Figure 1 and Figure 2 As shown, the upper cover 5 is provided with a through hole 521 for the pressure relief member 2 to pass through, the upper cover 5 is provided with a stopper 522, and the pressure relief member 2 is provided with a limiter 24. In the pressure relief position, the limiter 24 abuts against the stopper 522 to limit the downward displacement of the pressure relief member 2. When the limiter 24 abuts against the stopper 522, the pressure relief member 2 is in the pressure relief position where the pressure relief hole 71 can be opened. Therefore, the stopper cooperation between the limiter 24 and the stopper 522 limits the further downward displacement of the pressure relief member 2, which can give the user an obvious hand feeling prompt of being in place, and the explicit effect is stronger, which improves the user experience.

[0069] In a specific embodiment, the upper cover 5 includes an outer cover 51 and an inner cover 52 connected to each other, a through hole 521 is provided in the inner cover 52, and a sealing plug 7 is installed in the inner cover 52. The outer cover 51 is rotatably connected to the lower cover 6. The outer cover 51 and the inner cover 52 cooperate to form an activity space 10 for the operating member 1 and the pressure relief member 2 to move.

[0070] The specific implementation method for realizing the cover opening operation in this application can adopt any one of the following implementation methods:

[0071] Embodiment 3: One of the upper cover 5 and the lower cover 6 is provided with an active buckle, and the other of the two is provided with a buckle position adapted to the buckle. The upper cover 5 is locked or unlocked with the lower cover 6 by the snap-fitting of the active buckle and the buckle position. One of the upper cover 5 and the lower cover 6 is provided with a triggering member for triggering the action of the active buckle. The triggering member drives the action of the active buckle to disengage the active buckle from the buckle position, thereby unlocking the upper cover 5 and the lower cover 6. The triggering member and the operating member 1 in this embodiment 3 are different structural members, and the two are triggered independently to realize their respective functions. In other words, in this embodiment 3, the pressure relief action of the pressure relief member 2 and the unlocking action of the upper cover 5 are triggered by different structural members.

[0072] For example, the movable buckle is rotatably connected to the upper cover 5, and the trigger is also provided on the upper cover 5. The trigger can make a linear motion along the upper cover 5 under the action of an external force to drive the movable buckle to rotate, so that the movable buckle is disengaged from the buckle position, thereby unlocking the upper cover 5 and the lower cover 6. During use, the pressure relief member 2 is first moved by operating the operating member 1 to achieve pressure relief, and then the cover is opened by touching the trigger.

[0073] Implementation method 4: Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the cup cover assembly also includes a locking member 3, which is movably arranged on the upper cover 5 to have a locked position locked with the lower cover 6 and an unlocked position unlocked with the lower cover 6; the operating member 1 includes an operating portion 11 and an extrusion portion 12 connected to the operating portion 11. When the operating portion 11 is triggered, it drives the pressure relief member 2 to switch from the closed position to the pressure relief position, and simultaneously drives the extrusion portion 12 to push the locking member 3 to move so that the locking member 3 switches from the locked position to the unlocked position. In this fourth embodiment, the pressure relief and unlocking actions can be realized synchronously by triggering the operating member 1. A single trigger can open the cover in one step, which is simple and fast to operate and provides a better user experience.

[0074] In the fourth embodiment, the triggering mode of the operating unit 11 includes but is not limited to any one of the following embodiments:

[0075] Embodiment 3: The operating part 11 is rotatable relative to the upper cover 5, and the operating part 11 and the pressure relief member 2 are screw-coupled to drive the pressure relief member 2 to move up and down when the operating part 11 is screwed, so that the pressure relief member 2 is switched from the closed position to the pressure relief position.

[0076] Embodiment 4: The upper cover 5 is provided with an activity space 10 adapted to the operating part 11. The operating part 11 is pressed and triggered to drive the pressure relief part 2 to move up and down, so that the pressure relief part 2 is switched from the closed position to the pressure relief position. The locking part 3 is provided with a hook 31, and the lower cover 6 is provided with a position; in the locked position, the hook 31 is engaged with the position; in the unlocked position, the hook 31 is disengaged from the position. This embodiment 4 realizes pressure relief and unlocking by pressing, without twisting or prying open the upper cover 5, and can be realized by one-handed operation, which is easy and convenient to operate. In some specific scenarios, when only one hand can perform related operations, it is convenient for users to operate.

[0077] As a preferred example of this embodiment 4, Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the extrusion part 12 is rotatably connected to the upper cover 5, and a protruding push block is provided on the side of the extrusion part 12 facing the locking member 3. Furthermore, the upper cover 5 is provided with an elastic reset member, which is used to drive the locking member 3 to reset to a position where it can abut against the push block.

[0078] More specifically, Figure 5 and Figure 7 As shown, the extrusion part 12 includes a rotating shaft 121, a linkage plate 122 connected to the rotating shaft 121, and a push-out block provided on the side of the linkage plate 122 facing the locking member 3. In this example, the operating part 11 is pressed, the operating member 1 rotates around the rotating shaft 121, and the locking member 3 is squeezed by the push-out block, so that the hook 31 of the locking member 3 is disengaged from the locking position of the lower cover 6. When the operating part 11 is released, the locking member 3 is reset under the action of the elastic reset member and pushes the push-out block, thereby driving the operating part 11 to rotate and reset. This example can convert the rotational motion of the operating member 1 into the translational motion of the locking member 3, and the operation method is simple and fast, which improves the user experience.

[0079] As a preferred embodiment under implementation mode 4, Figure 1 and Figure 2 As shown, the cup cover assembly also includes an elastic member 8, the top end of the elastic member 8 abuts against the operating part 11, the bottom end of the elastic member 8 abuts against the pressure relief member 2, and the operating part 11 drives the pressure relief member 2 to move through the elastic member 8. In this embodiment, the drive between the operating part 11 and the pressure relief member 2 is a flexible drive, that is, the operating part 11 is not in direct contact with the pressure relief member 2, but is indirectly contacted through the elastic member 8 and on this basis, the pressure relief member 2 is driven to move by pressing the operating part 11. This method can well meet the solution of the operating part 11 driving the pressure relief member 2 and the locking member 3 at the same time, simplifies the structural design of the operating part 11 and the pressure relief member 2, and the whole operation is smoother and more natural. Exemplarily, the elastic member 8 is a spring.

[0080] As a preferred embodiment under implementation mode 4, Figure 1 and Figure 2 As shown, the side of the operating member 1 facing away from the lower cover 6 is provided with a convex curved protrusion, which is inclined toward the side where the upper cover 5 and the lower cover 6 are rotatably connected, so as to guide the user to press the operating portion 11 toward the side where the upper cover 5 and the lower cover 6 are rotatably connected, which has an obvious prompting effect and improves the user experience. Furthermore, a frosted surface, anti-slip texture or other anti-slip structures can be provided on the top surface of the operating member 1 to avoid slipping during the pressing process, so as to further improve the user experience.

[0081] The present application also discloses a thermos cup, comprising a cup body and a cup cover assembly provided at the cup mouth of the cup body, the cup cover assembly is the cup cover assembly described above, the lower cover 6 is installed at the cup mouth, and when the pressure relief member 2 is in the pressure relief position, the space in the cup body is connected to the external airflow through the pressure relief hole 71. The present application provides a pressure relief hole 71 on the sealing plug 7, and when the pressure relief hole 71 is opened, external air can enter the cup body from the pressure relief hole 71 and the water outlet 61 to achieve air pressure balance inside and outside the cup body, which helps to achieve a quick cover opening operation.
