Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a safety pressure relief cover structure and a water cup. Background Technology

[0002] With the rise of consumption upgrading and the increasing demand for leisure travel, the scenarios of traveling and staying in hotels are gradually increasing. However, the lack of hot water during trips and the unreliability of hotel kettles have led to the development of portable electric water cups, which can help users obtain clean and hygienic hot water while traveling or staying in hotels.

[0003] When an electric kettle is heated, steam is generated inside, which increases the air pressure inside the kettle. The kettle may explode due to excessive internal air pressure. Therefore, most electric kettles need to have the lid opened or have a vent on the lid to release the steam when heating. However, if the kettle is accidentally knocked over, the hot water inside will leak through the rim or vent. This may wet objects or even scald the user, posing a certain safety hazard. Utility Model Content

[0004] Therefore, it is necessary to provide a safe pressure relief cover structure and a water cup that can prevent water inside the cup from leaking out of the vent and can also release the steam inside the cup in a timely manner.

[0005] A safety pressure relief cap structure includes: a cap body having a first vent and a second vent, both of which connect to the outside and the inner cavity of a cup; a waterproof and breathable membrane covering the first vent; a straw assembly inserted into the cap body; and a top cover movably covering the cap body, wherein when the top cover is closed, it can seal the nozzle of the straw assembly and the second vent, and when the top cover is open, the nozzle and the second vent are connected to the outside.

[0006] This application provides a safety pressure relief cover structure. By setting a waterproof and breathable membrane on the first vent, when the electric water cup is heated, the membrane allows steam inside the cup to be discharged in real time, reducing the internal air pressure, while preventing liquid from flowing out of the first vent. Furthermore, since the breathability of the waterproof and breathable membrane has certain pressure requirements, in actual use, when the gas pressure inside the cup is lower than the pressure requirement of the membrane, some high-pressure steam cannot be discharged through it. If the top cover is opened to drink water at this time, the air pressure will cause hot water to spray out from the straw. Therefore, by setting a second vent on the cover body, and using the top cover to seal the second vent and the straw assembly, liquid leakage can be effectively prevented. When the user needs to drink water, the top cover can be opened to allow the second vent to connect to the outside, so that the remaining high-pressure steam can instantly overflow through the second vent, preventing hot water from spraying out of the straw, further improving the product's installation performance.

[0007] In one embodiment, the cover body has a mounting portion, which includes the first vent hole and a limiting cover. The limiting cover is detachably mounted on the mounting portion. The waterproof and breathable membrane is sandwiched between the limiting cover and the mounting portion. The limiting cover has a first vent hole, which connects to the outside or the inner cavity of the cup. By adopting the above structure, the detachable limiting cover facilitates the removal and installation of the waterproof and breathable membrane, providing convenience for user cleaning. Furthermore, the limiting cover and the mounting portion work together to sandwich the waterproof and breathable membrane, making it easier to position and install the membrane securely.

[0008] In one embodiment, the limiting cover includes a cover plate and a limiting protrusion. The cover plate has the first vent hole, and the limiting protrusion is disposed on the side of the cover plate near the mounting portion. The mounting portion has a limiting groove, and the limiting protrusion is adapted to be installed in the limiting groove. The waterproof and breathable membrane is sandwiched between the cover plate and the mounting portion, and the waterproof and breathable membrane is disposed opposite to the first vent hole. By adopting the above structure, the limiting cover can be quickly installed and removed through the cooperation of the limiting protrusion and the limiting groove, and ensures that the waterproof and breathable membrane can be tightly installed between the cover plate and the mounting portion, ensuring that the waterproof and breathable membrane effectively covers the first vent hole.

[0009] In one embodiment, the limiting cover further includes a shielding member connected to the cover plate and located inside the first vent. The shielding member divides the first vent into multiple smaller vents, providing a certain degree of dust prevention without affecting steam flow and preventing sharp objects from directly penetrating the limiting cover and cover assembly to puncture the waterproof and breathable membrane.

[0010] In one embodiment, the mounting portion is located on the side of the cover body near the top cover, and the limiting cover is located above the mounting portion. The limiting cover also includes multiple ribs, which are spaced apart on the side of the cover away from the mounting portion. By providing multiple ribs, when the nozzle is bent under the closed top cover, the multiple ribs raise the nozzle, preventing the nozzle from accidentally covering the first exhaust hole and affecting steam emission.

[0011] In one embodiment, the top of the lid body has a protruding mounting portion, and the limiting cap is located above the mounting portion. The mounting portion has a second vent hole, and the limiting cap has a second exhaust hole. The second exhaust hole communicates with the second vent hole. When the top cover is closed, it can block the second exhaust hole. When the top cover is open, the second exhaust hole communicates with the outside. By adopting the above structure, when the top cover is closed, it can block the second vent hole and interrupt its communication with the outside to prevent water leakage. When the top cover is open, the second vent hole can communicate with the outside through the second exhaust hole, allowing the remaining high-pressure steam inside the cup to be quickly discharged. Furthermore, by setting the mounting portion and the limiting cap to protrude from the top wall of the lid body, the length of the pressing part where the top cover abuts against the limiting cap and / or the spout can be shortened, reducing the risk of breakage.

[0012] In one embodiment, the top cover has a pressing portion formed on the side facing the cover body. When the top cover is closed, the pressing portion presses the suction nozzle against the second exhaust hole to seal the second exhaust hole.

[0013] In one embodiment, a pressing part is formed on the side of the top cover facing the cover body. When the top cover is closed, the pressing part presses the nozzle against the second vent hole to seal the second vent hole. Specifically, after the electric water cup is filled with water, closing the top cover allows the nozzle to be pressed against the second vent hole by the pressing part, thus simultaneously sealing the second vent hole and the nozzle to prevent liquid leakage. When the electric water cup is boiling water, the second vent hole and the nozzle remain sealed, and the high-pressure steam generated inside the cup will be discharged from the waterproof and breathable membrane, preventing excessive pressure from causing the lid to burst. After boiling is finished, the top cover can be opened, allowing the nozzle to separate from the pressing part and the nozzle to elastically return to its original position, thereby opening the second vent hole to the outside. The remaining high-pressure steam can instantly overflow through the second vent hole, preventing the straw from spraying hot water and further improving the installation performance of the product.

[0014] In one embodiment, the top cover and the cover body enclose a receiving cavity, and the top cover is provided with a third vent hole. The receiving cavity connects the first vent hole and the third vent hole. By adopting the above structure, steam enters the receiving cavity after passing through the waterproof and breathable membrane and is discharged to the outside through the third vent hole. Under the protection of the top cover, it not only serves to prevent dust and sharp objects from directly piercing the waterproof and breathable membrane through the first vent hole, but also prevents steam from directly escaping and scalding the user, further improving safety.

[0015] In one embodiment, at least a portion of the suction nozzle is located within the receiving cavity.

[0016] In one embodiment, a first latch is further included, which is disposed on the cover body. The top cover has a first hook, which is used to lock and engage with the first latch when the top cover is closed. The first latch is used to maintain the closed state of the top cover, which on the one hand prevents liquid leakage caused by the top cover opening during a collision with the safety pressure relief cover structure, and on the other hand effectively avoids the risk of steam burns or hot water spraying from the straw caused by accidental opening of the top cover during heating.

[0017] In one embodiment, the top cover is rotatably connected to the cover body via a pivot.

[0018] In one embodiment, the lid body includes a first lid and a second lid. The second lid is used to cover the opening of the cup body and / or the inner liner. The first lid has a first vent hole and a second vent hole, and the second lid has a liquid outlet. The straw assembly includes a mouthpiece and a tube. The mouthpiece is inserted into the first lid, and the tube is inserted into the second lid. The first lid is movably positioned above the second lid. When the first lid is closed, the mouthpiece is connected to the tube, and the liquid outlet communicates with the first vent hole and the second vent hole respectively. When the first lid is opened, the mouthpiece is separated from the tube, and the liquid outlet is exposed to the outside. By adopting the above structure, when the first lid is closed, the steam in the cup will flow from the liquid outlet to the waterproof and breathable membrane and the second vent hole to be discharged. When the first lid is opened, the liquid outlet can be directly exposed. Thus, the safety pressure relief lid structure can be used for both straw and direct drinking methods.

[0019] In one embodiment, the first cover is rotatably connected to the second cover via a pivot.

[0020] In one embodiment, a sealing ring is further included, located between the first cover and the second cover. The sealing ring seals the gap between the end face of the liquid outlet and the first cover when the first cover is closed. By employing this structure, when the first cover is closed, the sealing ring presses the closed first cover tightly against the liquid outlet, improving the airtightness of the gap between the end face of the liquid outlet and the first cover, thereby preventing liquid and vapor leakage from the liquid outlet.

[0021] In one embodiment, the first cover has an annular protrusion on the side near the second cover. The sealing ring includes an annular sealing portion and an annular outer sleeve. The annular sealing portion is disposed at the bottom of the annular outer sleeve, and the annular outer sleeve is fitted over the outside of the annular protrusion. When the first cover is closed, the two sides of the annular sealing portion abut against the annular protrusion and the end face of the liquid outlet, respectively. By adopting the above structure, the sealing ring can be fixedly fitted onto the annular protrusion, thereby allowing the sealing ring to connect and separate from the end face of the liquid outlet as the first cover moves.

[0022] In one embodiment, the nozzle includes a nozzle body and a limiting step. The limiting step is disposed on the outer side wall of the nozzle body. The first cover has a mounting hole, and the nozzle body is fitted into the mounting hole. The limiting step abuts against the end face of the mounting hole near the second cover. By adopting the above structure, the limiting step abuts against the end face of the mounting hole, further cooperating with the mounting hole to limit the nozzle, making the nozzle easy and quick to install and less prone to loosening.

[0023] In one embodiment, the nozzle body is connected to the sealing ring via the limiting step.

[0024] In one embodiment, the suction nozzle and the sealing ring are integrally formed.

[0025] In one embodiment, a second latch is further included, which is disposed on the second cover. The first cover has a second hook, which is used to lock into the second latch when the first cover is closed. The second latch is used to maintain the closed state of the first cover, preventing liquid leakage through the outlet from occurring when the safety relief cover structure is impacted and the first cover opens.

[0026] A second aspect of this application provides a water cup.

[0027] A water cup includes: a cup body; and the aforementioned safety pressure relief cap structure, wherein the safety pressure relief cap structure is used to cover the opening of the cup body. The water cup provided in the second aspect of this application, by employing the safety pressure relief cap structure of any of the above embodiments, utilizes a waterproof and breathable membrane on the first vent. When the liquid inside the cup is heated, the membrane allows steam to escape in real time, reducing internal pressure, while preventing liquid from flowing out of the first vent. Furthermore, a second vent is provided. When the cup is filled with liquid, the top cover seals the second vent and the straw assembly, effectively preventing liquid leakage. When the user needs to drink, the top cover can be opened to allow the second vent to connect to the outside, allowing any remaining high-pressure steam that failed to escape through the waterproof and breathable membrane to overflow instantly through the second vent, preventing hot water from spraying out of the straw and further improving the product's installation performance.

[0028] In one embodiment, the cup also includes an inner liner and a heating assembly, the inner liner being disposed within the cup body, the safety pressure relief cap structure being used to cover the opening of the cup body and / or the inner liner, and the heating assembly being disposed at the bottom of the cup body for heating the liquid inside the inner liner.

[0045] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0046] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0047] The safety pressure relief cover structure of some embodiments of the present invention is described below with reference to the accompanying drawings.

[0048] like Figures 1 to 6 As shown, this embodiment discloses a safety pressure relief cover structure, including: a cover body 1, the cover body 1 having a first vent 101 and a second vent 102, both the first vent 101 and the second vent 102 being used to connect the outside and the inner cavity of the cup; a waterproof and breathable membrane 2, the waterproof and breathable membrane 2 covering the first vent 101; a straw assembly 3, the straw assembly 3 being inserted into the cover body 1; and a top cover 4, the top cover 4 being movably positioned above the cover body 1, the top cover 4 being able to seal the mouthpiece 31 of the straw assembly 3 and the second vent 102 respectively when closed, and the mouthpiece 31 and the second vent 102 being connected to the outside when the top cover 4 is open.

[0049] This application provides a safe pressure relief cover structure. By setting a waterproof and breathable membrane 2 on the first vent 101, when the electric hot water cup is heated, the steam inside the cup can be discharged in real time through the waterproof and breathable membrane 2 to reduce the internal air pressure, while preventing the liquid inside the cup from flowing out from the first vent 101. Furthermore, since the breathability function of the waterproof and breathable membrane 2 has certain pressure requirements, in actual use, when the gas pressure inside the cup is less than the pressure requirement of the waterproof and breathable membrane 2, some of the high-pressure steam inside the cup cannot be discharged through the waterproof and breathable membrane 2. At this time, if the top cover 4 is opened to drink water, the air pressure will spray hot water out from the straw. Therefore, by setting a second vent 102 on the cover body 1, and using the top cover 4 to seal the second vent 102 and the straw assembly 3, it is possible to effectively ensure that the liquid will not leak. When the user needs to drink water, the top cover 4 can be opened to allow the second vent 102 to connect to the outside, so that the remaining high-pressure steam can overflow instantly through the second vent 102, preventing hot water from being sprayed out from the straw, and further improving the installation performance of the product.

[0050] like Figures 3 to 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the cover body 1 has a mounting portion 111, the mounting portion 111 is provided with a first vent hole 101, and also includes a limiting cover 5, the limiting cover 5 is detachably mounted on the mounting portion 111, the waterproof and breathable membrane 2 is sandwiched between the limiting cover 5 and the mounting portion 111, the limiting cover 5 is provided with a first vent hole 501, and the first vent hole 101 communicates with the outside or the inner cavity of the cup through the first vent hole 501. By adopting the above structure, the detachable limiting cover 5 facilitates the removal and installation of the waterproof and breathable membrane 2, providing convenience for user cleaning, and the limiting cover 5 cooperates with the mounting portion 111 to sandwich the waterproof and breathable membrane 2 between them, which makes it easier to position the waterproof and breathable membrane 2 and makes the installation more secure.

[0051] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the limiting cover 5 includes a cover plate 51 and a limiting protrusion 52. The cover plate 51 is provided with a first vent hole 501, and the limiting protrusion 52 is disposed on the side of the cover plate 51 near the mounting part 111. The mounting part 111 is provided with a limiting groove 103, and the limiting protrusion 52 is adapted to be installed in the limiting groove 103. The waterproof and breathable membrane 2 is sandwiched between the cover plate 51 and the mounting part 111, and the waterproof and breathable membrane 2 is disposed opposite to the first vent hole 501. By adopting the above structure, the limiting cover 5 can be quickly installed and removed through the cooperation of the limiting protrusion 52 and the limiting groove 103, and ensures that the waterproof and breathable membrane 2 can be tightly disposed between the cover plate 51 and the mounting part 111, and ensures that the waterproof and breathable membrane 2 effectively covers the first vent hole 101.

[0052] like Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the limiting cover 5 also includes a shielding member 54, which is connected to the cover plate 51 and is located inside the first vent hole 501. The shielding member 54 can divide the first vent hole 501 into multiple smaller vent holes, providing a certain degree of dust prevention without affecting steam flow, and preventing sharp objects from directly penetrating the limiting cover 5 and the cover assembly to puncture the waterproof and breathable membrane 2.

[0053] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting part 111 is located on the side of the cover body 1 near the top cover 4, the limiting cover 5 is located above the mounting part 111, and the limiting cover 5 also includes a plurality of protruding ribs 53, which are spaced apart on the side of the cover plate 51 away from the mounting part 111. By providing the plurality of protruding ribs 53, when the suction nozzle 31 is bent under the closed top cover 4, the plurality of protruding ribs 53 can be used to raise the suction nozzle 31, preventing the suction nozzle 31 from accidentally covering the first exhaust port 501 and affecting steam emission.

[0054] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a mounting portion 111 is formed on the top of the lid body 1, a limiting cover 5 is located above the mounting portion 111, the mounting portion 111 is provided with a second vent hole 102, and the limiting cover 5 is provided with a second exhaust hole 502. The second exhaust hole 502 communicates with the second vent hole 102. When the top cover 4 is closed, it can block the second exhaust hole 502. When the top cover 4 is open, the second exhaust hole 502 communicates with the outside. By adopting the above structure, when the top cover 4 is closed, it can block the second vent hole 102 from communicating with the outside by covering the second exhaust hole 502 to prevent water leakage. When the top cover 4 is open, the second vent hole 102 can communicate with the outside through the second exhaust hole 502, allowing the remaining high-pressure steam inside the cup to be quickly discharged. By setting the mounting portion 111 and the limiting cover 5 to protrude from the top wall of the lid body 1, it is beneficial to shorten the length of the pressing portion 41 where the top cover 4 abuts against the limiting cover 5 and / or the spout 31, reducing the risk of breakage.

[0055] like Figures 2 to 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a pressing part 41 is formed on the side of the top cover 4 facing the cover body 1, and when the top cover 4 is closed, the pressing part 41 presses the suction nozzle 31 against the second exhaust hole 502 to seal the second exhaust hole 502.

[0056] In addition to the features of the above embodiments, this embodiment further specifies that: a pressing part 41 is formed on the side of the top cover 4 facing the cover body 1. When the top cover 4 is closed, the pressing part 41 presses the nozzle 31 against the second vent hole 102 to seal the second vent hole 102. Specifically, after the electric water cup is filled with water, closing the top cover 4 allows the nozzle 31 to be pressed against the second vent hole 102 by the pressing part 41, thus simultaneously sealing the second vent hole 102 and the nozzle 31 to prevent liquid leakage. When the electric water cup is boiling water, the second vent hole 102 and the nozzle 31 remain sealed, and the high-pressure steam generated inside the cup will be discharged from the waterproof and breathable membrane 2 to prevent excessive pressure from causing the lid to burst. After boiling water is finished, the top cover 4 can be opened, allowing the nozzle 31 to separate from the pressing part 41 and the nozzle 31 to elastically return to its original position. This allows the second vent hole 102 to connect to the outside, and the remaining high-pressure steam can instantly overflow through the second vent hole 102, preventing the straw from spraying hot water and further improving the installation performance of the product.

[0057] like Figures 2 to 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the top cover 4 and the cover body 1 enclose a receiving cavity 401, the top cover 4 is provided with a third vent 402, and the receiving cavity 401 connects the first vent 101 and the third vent 402. By adopting the above structure, steam enters the receiving cavity 401 after passing through the waterproof and breathable membrane 2 and is discharged to the outside through the third vent 402. Under the cover and protection of the top cover 4, it not only serves to prevent dust and prevent sharp objects from directly penetrating the waterproof and breathable membrane 2 through the first vent 101, but also avoids steam directly escaping and scalding the user, further improving safety.

[0058] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that at least a portion of the suction nozzle 31 is located in the receiving cavity 401.

[0059] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further includes a first latch 7, which is disposed on the cover body 1. The top cover 4 has a first hook 42, which is used to lock and engage with the first latch 7 when the top cover 4 is closed. By using the first latch 7 to keep the top cover 4 closed, on the one hand, it can prevent the top cover 4 from opening and causing liquid leakage when the safety pressure relief cover structure is impacted; on the other hand, it can effectively avoid the risk of steam burns or hot water spraying from the straw caused by the top cover 4 accidentally opening during heating.

[0060] like Figure 1 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the top cover 4 is rotatably connected to the cover body 1 via a rotating shaft 6.

[0061] like Figure 2 , Figure 3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines: the cover body 1 includes a first cover 11 and a second cover 12, the second cover 12 is used to cover the opening of the cup body and / or the inner liner, the first cover 11 is provided with a first vent hole 101 and a second vent hole 102, the second cover 12 is provided with a liquid outlet 104, the straw assembly 3 includes a suction nozzle 31 and a tube body 32, the suction nozzle 31 is inserted on the first cover 11, the tube body 32 is inserted on the second cover 12, the first cover 11 is movably covered above the second cover 12, when the first cover 11 is closed, the suction nozzle 31 is connected to the tube body 32, and the liquid outlet 104 is connected to the first vent hole 101 and the second vent hole 102 respectively, when the first cover 11 is opened, the suction nozzle 31 is separated from the tube body 32, and the liquid outlet 104 is exposed to the outside. By adopting the above structure, when the first cover 11 is closed, the steam in the cup will flow from the liquid outlet 104 to the waterproof and breathable membrane 2 and the second vent 102 and be discharged. When the first cover 11 is opened, the liquid outlet 104 can be directly exposed. Thus, the safety pressure relief cover structure can be used for both straw and direct drinking methods.

[0062] like Figures 1 to 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first cover 11 is rotatably connected to the second cover 12 via a rotating shaft 6.

[0063] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further includes a sealing ring 8, located between the first cover 11 and the second cover 12. The sealing ring 8 is used to seal the gap between the end face of the liquid outlet 104 and the first cover 11 when the first cover 11 is closed. By adopting the above structure, when the first cover 11 is closed, the sealing ring 8 presses the closed first cover 11 tightly against the liquid outlet 104, thereby improving the airtightness of the gap between the end face of the liquid outlet 104 and the first cover 11, thus preventing liquid and vapor from leaking outward from the liquid outlet 104.

[0064] like Figure 3 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: an annular protrusion 112 is formed on the side of the first cover 11 near the second cover 12; the sealing ring 8 includes an annular sealing portion 81 and an annular outer sleeve 82; the annular sealing portion 81 is disposed at the bottom of the annular outer sleeve 82; and the annular outer sleeve 82 is fitted over the outside of the annular protrusion 112. When the first cover 11 is closed, the two sides of the annular sealing portion 81 abut against the end faces of the annular protrusion 112 and the liquid outlet 104, respectively. By adopting the above structure, the sealing ring 8 can be fixedly fitted onto the annular protrusion 112, thereby allowing the sealing ring 8 to connect and separate from the end face of the liquid outlet 104 as the first cover 11 moves.

[0065] like Figure 3 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the suction nozzle 31 includes a suction nozzle body 311 and a limiting step 312. The limiting step 312 is disposed on the outer side wall of the suction nozzle body 311. The first cover 11 is provided with a mounting hole 105. The suction nozzle body 311 is fitted and installed with the mounting hole 105. The limiting step 312 abuts against the end face of the mounting hole 105 near the second cover 12. By adopting the above structure, the abutment between the limiting step 312 and the end face of the mounting hole 105 can further cooperate with the mounting hole 105 to form a limiting effect on the suction nozzle 31, so that the suction nozzle 31 can be easily and quickly installed and is not easy to loosen.

[0066] like Figure 3 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the nozzle body 311 is connected to the sealing ring 8 through the limiting step 312.

[0067] like Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the nozzle 31 and the sealing ring 8 are integrally formed.

[0068] like Figure 3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further includes a second latch 9, which is disposed on the second cover 12. The first cover 11 has a second hook 113, which is used to lock and engage with the second latch 9 when the first cover 11 is closed. The second latch 9 is used to maintain the closed state of the first cover 11, preventing the first cover 11 from opening and causing liquid leakage through the outlet 104 when the safety pressure relief cover structure is impacted.

[0069] A second aspect of this application provides a water cup.

[0070] This embodiment discloses a water cup, including: a cup body; and the aforementioned safety pressure relief cap structure, which is used to cover the opening of the cup body. The water cup provided in the second aspect of this application, by employing the safety pressure relief cap structure of any of the above embodiments, and by providing a waterproof and breathable membrane 2 on the first vent 101, allows steam to be discharged through the waterproof and breathable membrane 2 in real time when the liquid inside the cup is heated, reducing internal pressure, while also preventing the liquid inside the cup from flowing out from the first vent 101. Furthermore, a second vent 102 is provided. When the water cup is filled with liquid, the top cover 4 seals the second vent 102 and the straw assembly 3, effectively ensuring that the liquid does not leak. When the user needs to drink water, the top cover 4 can be opened to allow the second vent 102 to connect to the outside, so that any remaining high-pressure steam that could not be discharged through the waterproof and breathable membrane 2 can instantly overflow through the second vent 102, preventing hot water from spraying out of the straw, further improving the product's installation performance.
