In some embodiments, the key switch 150 includes a second position-limiting portion protruding out of the upper cover 110; the cover 120 is provided with a third position-limiting portion that can be engaged with the second position-limiting portion. Under the condition that the key switch 150 is pressed, the third limiting part releases the limitation of the second limiting part, so that a user can rotate the upper cover 110 conveniently and drive the key switch 150 to move. Under the condition that the key is not pressed, the third limiting part can limit the second limiting part, so that the upper cover 110 can only drive the key switch 150 to rotate to the position of the third limiting part, excessive rotation of the upper cover 110 is avoided, the upper cover 110 can directly rotate to a set position, and effective sealing or sealing releasing of the cup opening sealing element 140 is realized.

In some embodiments, the key switch 150 can move laterally on the upper cover 110, and the second position-limiting portion is a rib 152; the cover 120 is provided with a slot 122 having a notch facing the central axis of the cover 120, and the slot 122 constitutes a third limiting portion. When the key switch 150 is pressed, the rib 152 can be disengaged from the slot 122 from the notch of the slot 122, and rotates to any position with the upper cover 110 relative to the cover body 120; when the key switch 150 is not pressed, the rib 152 can rotate with the upper cover 110 until it extends into the slot 122. The rotation position of the upper cover 110 is limited by the clamping groove 122 and the convex rib 152, the structure is simple, the operation is convenient, and the position of the second limiting part can be adjusted by only pressing the key switch 150.

In some embodiments, the key switch 150 includes a key body 151, a rib 152 extending downward from a lower surface of the key body 151, a slot 122 formed by two ribs extending radially inward from an inner sidewall of the cover body 120, the two ribs extending in an up-down direction to form two slot sidewalls of the slot 122, and an upper portion and a radially inner side of the slot 122 forming an opening, and the cover 110 can be rotated relative to the cover body 120 with the rib 152 inserted into the slot 122 from above.

In some embodiments, at least one of the slot sidewalls of the slot 122 has a guide surface 123 such that the rib 152 can extend into the slot 122 along the guide surface 123 after the upper cover 110 is rotated to a position where the slot 122 is located.

In a particular application, the guide surface 123 is a guide slope or an arc surface.

In a specific application, the number of the card slots 122 is two, one slot sidewall of each card slot 122 has a guiding surface 123, and the two guiding surfaces 123 are distributed oppositely.

In some embodiments, the number of card slots 122 is two, namely a first card slot 122 and a second card slot 122; under the condition that the upper cover 110 rotates to the first position relative to the cover body 120 and the key switch 150 is not pressed, the convex rib 152 extends into the first slot 122; when the upper cover 110 is rotated to the second position relative to the cover 120 and the key switch 150 is not pressed, the rib 152 extends into the second slot 122. By providing two engaging slots 122, it is beneficial to enable the cup sealing member 140 to tightly seal the gap between the cup 160 and the valve cap 130 when the upper cover 110 rotates to the first position, and to enable the cup sealing member 140 to reset when the upper cover 110 rotates to the second position. The upper cover 110 is limited by the two clamping grooves 122, so that the upper cover 110 can be rotated accurately by a user.

In a specific application, one slot sidewall of each slot 122 has a guide surface 123, and the two guide surfaces 123 are oppositely disposed.

In some embodiments, the valve cover 130 is provided with an exhaust channel 134, and the key switch 150 can also control the on/off of the exhaust channel 134. On one hand, the on-off of the exhaust channel 134 can be realized through the key switch 150, so that the pressure relief of the gas in the cup body 160 is facilitated, and the subsequent opening of the cup cover assembly by a user is facilitated. On the other hand, the key switch 150 can control the pressure release and the rotation position of the upper cover 110, compared with the control by two keys, the structure is simplified, and the space utilization rate of the cup cover assembly is reduced. In addition, the upper cover 110 can be rotated relative to the cover body 120 only by pressing the key switch 150, that is, in the using process, the key switch 150 needs to be pressed to release pressure and exhaust air, and then the upper cover 110 is rotated, so that the problem that the disassembly of the cup cover assembly is influenced by the overlarge pressure in the cup body 160 can be effectively avoided.

In a specific application, the key switch 150 may have at least one stroke position, for example, when the key switch 150 moves to the third position, the third position-limiting portion releases the position-limiting on the second position-limiting portion, and the user can rotate the upper cover 110 to move relative to the cover 120, and at the same time, the key switch 150 can enable the exhaust channel 134 to communicate with the cup 160 and the external environment. For another example, when the key switch 150 moves to the fourth position, the key switch 150 can enable the exhaust channel 134 to communicate with the cup 160 and the external environment, so as to release the pressure and exhaust of the cup 160, and then continuously press the key switch 150 to move to the fifth position, the third limiting portion releases the limitation of the second limiting portion, so that the user can rotate the upper cover 110 to move relative to the cover 120. For example, the upper cover 110 may be rotated to the first position, so that the valve rod 135 moves upward along with the valve cover 130 to the set position, and then the push switch 150 is pressed to open the exhaust channel 134; for example, by moving push button switch 150 to the sixth position, valve stem 135 is pressed by push button switch 150, thereby pushing valve stem 135 into cup 160 to open vent passage 134.

In a specific application, when the push button switch 150 is pressed and the upper cover 110 is rotated for a certain number of turns, the valve cover 130 is driven by the screw to move downwards for a certain distance, otherwise, the valve cover 130 is shortened for a certain distance.

When the rim sealing member 140 deforms, water can be sealed through the outward deformation part of the rim sealing member 140, and meanwhile, the rim sealing member, the inner diameter-changing part 163 of the cup body 160 and the valve cover 130 are extruded to achieve the fixing function of the cup cover assembly and the cup body 160, which is the same as the thread. Otherwise, the lid assembly may be opened easily after the rim seal 140 is restored. In addition, the locked state (i.e., the state where the cup seal 140 seals the gap between the cup 160 and the bonnet 130) and the fully opened state (i.e., the state where the cup seal 140 is not pressed and is reset) of the upper cover 110 are provided with click feedback and indication, which facilitates the user to rotate the upper cover 110 in place. In addition, when the cup cover assembly is locked and completely opened, the cup cover assembly can be opened or closed by pressing the exhaust button (namely the key switch 150) to rotate, when the exhaust button is pressed, the internal air pressure is released to play a role of internal pressure relief, the exhaust button is pressed all the time, and the upper cover 110 is rotated, so that the cup cover assembly can be disassembled and cleaned.

In a specific application, the end of the key body 151 facing the valve stem 135 has a guiding inclined surface, the key switch 150 moves a certain distance, the guiding inclined surface drives the valve stem 135 to move downward a certain distance, and the exhaust channel sealing element 137, such as a sealing ring, on the valve stem 135 is exposed out of the exhaust channel 134, and a gap between the valve stem 135 and the bonnet 130 is exposed for exhaust.

In some embodiments, the lid assembly further includes a first indicator disposed on the lid body 120 and a second indicator disposed on the upper lid 110; in a case where the upper cover 110 is rotated to the first position or the second position with respect to the cover body 120, the position of the first indicator corresponds to the position of the second indicator. The upper cover 110 can be rotated by the user according to the positions of the first indicator and the second indicator, so that the upper cover 110 can be rotated in place, and the phenomenon that the deformation of the cup sealing element 140 is influenced due to the excessive rotation or the insufficient rotation of the upper cover 110, so that the sealing performance is influenced and the like can be avoided.

In a specific application, the first indicator and the second indicator can be stickers, and can also be a protrusion 164 or a groove, which is convenient for a user to observe and realize the alignment of the two indicators.

In some embodiments, the lid assembly further includes a first protruding point disposed on the lid 120 and a second protruding point disposed on the upper lid 110; when the upper cover 110 is rotated to the first position or the second position with respect to the cover 120, the first bumps and the second bumps collide.
