[0035] The steam humidifier 100 and steam valve 40 according to an embodiment of the present invention will be described below with reference to Figures 1-9.

[0036] Referring to Figure 1, the steam humidifier 100 according to an embodiment of the present invention comprises a steam generating body 1, a steam generating chamber 11 provided in the steam generating body 1, the steam generating chamber 11 is used to hold water, and the steam generating body 1 can generate steam in the steam generating chamber 11 by heating the water to a boiling state.

[0037] Referring to Figures 1 and 2, the steam humidifier 100 further comprises a lid assembly 2, which is mounted on the steam generating body 1, and the lid assembly 2 is provided with an exhaust port (not shown) and a fluid passage 29 lower than the exhaust port, and the exhaust port and the fluid passage 29 are each connected to the steam generating chamber 11.

[0038] Steam can flow into the lid assembly 2 through the exhaust port and also flow within the lid assembly 2. During the steam flow process, the steam condenses to generate condensed water, which can then flow back into the steam generation chamber 11 via the fluid passage 29. There, it is reheated and evaporated to generate steam, enabling the recovery and reuse of condensed water and reducing the waste of water resources.

[0039] The fluid passage 29 is located closer to the steam generation chamber 11 than the exhaust port, meaning that the fluid passage 29 is located lower than the exhaust port. This helps to ensure that condensed water from steam condensation is returned through the fluid passage 29, and also helps to reduce the risk of condensed water flowing into the exhaust port and blocking it.

[0040] Referring to Figures 1 to 4, the steam humidifier 100 further comprises a steam valve 40, which is mounted on the lid assembly 2 so as to be movable between a first position and a second position to selectively seal the fluid passage 29.

[0041] During the process of changing the steam humidifier 100 from a normal upright state to an inverted state, the steam valve 40 moves between a first position and a second position. For example, when the steam humidifier 100 is in a normal upright state, the steam valve 40 can be in the first position, at which time the fluid passage 29 is open, and condensed water can flow back into the steam generation chamber 11 through the fluid passage 29. After the steam humidifier 100 inverts, the steam valve 40 moves from the first position to the second position to seal the fluid passage 29, preventing high-temperature water in the steam generation chamber 11 from leaking through the fluid passage 29 after the steam humidifier 100 inverts, thereby effectively improving the safety of use of the steam humidifier 100.

[0042] To make it easier to understand, the position in which the steam valve 40 seals the fluid passage 29 may be defined as the first position, and the position in which the fluid passage 29 is open may be defined as the second position. Specifically, the first and second positions are not specifically limited here, and the steam valve 40 can move between the first and second positions and selectively seal the fluid passage 29.

[0043] Referring to Figure 5, the end of the fluid passage 29 furthest from the exhaust port is the first end 291, and a water reservoir groove 41 is provided in the steam valve 40, with a portion of the first end 291 entering the water reservoir groove 41.

[0044] When the steam humidifier 100 is in a normal upright position, a portion of the first end 291 closest to the steam generating chamber 11 enters the water reservoir groove 41. At this time, the first end 291 and the water reservoir groove 41 are spaced apart, allowing the fluid passage 29 to remain open. Condensed water can fall into the water reservoir groove 41 via the fluid passage 29 and accumulate in the water reservoir groove 41. When the liquid level of the condensed water in the water reservoir groove 41 is flush with the end of the first end 291 closest to the steam generating chamber 11, or when the end of the first end 291 closest to the steam generating chamber 11 is submerged in the water reservoir groove 41, the condensed water in the water reservoir groove 41 can seal the fluid passage 29, preventing steam from leaking out of the fluid passage 29 and helping to prevent high-temperature steam leaking from the fluid passage 29 from burning the user.

[0045] At the same time, when steam leaks from the fluid passage 29, the steam flow path interferes with the condensate flow path, affecting the reflux of condensate. By sealing the fluid passage 29, it is possible to prevent steam leakage from affecting the reflux of condensate and ensure the smooth reflux of condensate.

[0046] In the embodiment of the present invention, the steam humidifier 100 is provided with a movable steam valve 40 in the lid assembly 2. When the steam humidifier 100 is in a normal upright position, the steam valve 40 opens the fluid passage 29, allowing condensed water to flow into the water reservoir groove 41 via the fluid passage 29. The condensed water also seals the fluid passage 29, preventing high-temperature steam from leaking out of the fluid passage 29. Furthermore, steam leakage can be prevented from interfering with the recirculation of condensed water. If the steam humidifier 100 tips over, the steam valve 40 can be moved to a position that seals the fluid passage 29, preventing high-temperature water in the steam generation chamber 11 from leaking out of the fluid passage 29 after the steam humidifier 100 tips over, thereby improving the safety of use of the steam humidifier 100.

[0047] The steam humidifier 100 may also be a humidifier.

[0048] Referring to Figures 1 and 2, in some embodiments of the present invention, the steam valve 40 is inserted into the fluid passage 29 and defines a recirculation passage 50 between itself and the inner circumferential wall of the fluid passage 29, and at a first position, a water reservoir groove 41 and a first end 291 are provided at a distance from each other to connect the recirculation passage 50 and the steam generation chamber 11.

[0049] When the steam humidifier 100 is in a normal upright position, the steam valve 40 is in the first position, and at this time, the water reservoir groove 41 and the first end 291 are spaced apart, the return passage 50 is in communication with the water reservoir groove 41 so that condensed water can flow through the return passage 50 and then into the water reservoir groove 41, and when the liquid level of the condensed water in the water reservoir groove 41 is flush with the end of the first end 291 closest to the steam generation chamber 11, or when it is immersed in the end of the first end 291 closest to the steam generation chamber 11, the condensed water in the water reservoir groove 41 can seal the fluid passage 29 and prevent steam leakage.

[0050] When the water reservoir 41 is filled with condensed water and the condensed water continues to flow into the water reservoir 41 via the recirculation passage 50, the condensed water in the water reservoir 41 overflows and flows into the steam generation chamber 11. The condensed water is then reheated and evaporated in the steam generation chamber 11 to form steam, thus enabling the recovery and utilization of the condensed water.

[0051] Referring to Figures 3 and 4, at the second position, the water reservoir groove 41 comes into contact with the first end 291 and seals the fluid passage 29.

[0052] After the steam humidifier 100 tips over, the steam valve 40 moves to a second position, at which point the water reservoir groove 41 comes into contact with the first end 291. The groove wall of the water reservoir groove 41 seals the fluid passage 29, blocking communication between the recirculation passage 50 and the steam generation chamber 11. This prevents high-temperature water in the steam generation chamber 11 from leaking through the fluid passage 29 and burning the user, thereby improving the safety of using the steam humidifier 100.

[0053] Referring to Figures 1 to 4, in some embodiments of the present invention, the steam valve 40 is configured such that its center of gravity is located on the exhaust port side of the fluid passage 29, making it suitable for moving the steam valve 40 toward a second position under the action of gravity.

[0054] If the center of gravity of the steam valve 40 is on the opposite side of the fluid passage 29 from the steam generation chamber 11, when the steam humidifier 100 is in a normal upright position, the water reservoir groove 41 and the first end 291 of the fluid passage 29 are spaced apart, and the fluid passage 29 is in an open state. After the steam humidifier 100 tips over, since the center of gravity of the steam valve 40 is on the opposite side of the fluid passage 29 from the steam generation chamber 11, the steam valve 40 moves to the side away from the steam generation chamber 11 under the influence of gravity and slides towards the ground, that is, the steam valve 40 moves to a second position under the influence of gravity, and when the steam valve 40 moves to the second position, the groove wall of the water reservoir groove 41 comes into contact with the first end 291 of the fluid passage 29, sealing the fluid passage 29.

[0055] Referring to Figures 5 and 6, in some embodiments of the present invention, the steam valve 40 includes a plug 42, the outer circumferential wall of the plug 42 is provided with a contact rib 421, the contact rib 421 abuts against the fluid passage 29, and defines a recirculation passage 50 between the plug 42 and the fluid passage 29.

[0056] The plug 42 is inserted into the fluid passage 29, and by providing a contact rib 421 on the outer circumferential wall of the plug 42, the contact rib 421 can be supported by the inner circumferential wall of the fluid passage 29, and a gap is provided between the outer circumferential wall of the plug 42 and the inner circumferential wall of the fluid passage 29, thereby defining a recirculation passage 50 between the plug 42 and the fluid passage 29, which prevents condensed water from flowing into the steam generation chamber 11 through the recirculation passage 50 and from coming into contact with the inner circumferential wall of the fluid passage 29, thus improving the smoothness of condensed water recirculation.

[0057] Referring to Figures 5, 6, and 8, the steam valve 40 further comprises a sealing member 43, which is provided on the plug 42 and located on the steam generation chamber 11 side of the fluid passage 29. The sealing member 43 defines and forms a water reservoir groove 41, which is connected to the recirculation passage 50. Condensed water can flow from the recirculation passage 50 into the water reservoir groove 41. When the water reservoir groove 41 is filled with condensed water and condensed water continues to flow into the water reservoir groove 41, the condensed water can overflow from the water reservoir groove 41 and flow into the steam generation chamber 11.

[0058] Referring to Figure 5, when the steam valve 40 is in the first position, the sealing member 43 and the first end 291 are spaced apart, and the first end 291 is spaced apart from the groove wall of the water reservoir groove 41. The recirculation passage 50 is connected to the steam generation chamber 11 via the water reservoir groove 41, and condensed water is allowed to flow into the steam generation chamber 11 from the recirculation passage 50.

[0059] As shown in Figure 4, when the steam valve 40 is in the second position, the sealing member 43 may be understood to be in contact with the first end 291, and the first end 291 may be understood to be in contact with the groove wall of the water reservoir groove 41, thereby blocking communication between the recirculation passage 50 and the steam generation chamber 11, preventing high-temperature water in the steam generation chamber 11 from leaking further from the recirculation passage 50 after it has flowed into the lid assembly 2, thereby reducing the risk of high-temperature water leaking and burning the user after the steam humidifier 100 tips over, which is advantageous in improving the safety of use of the steam humidifier 100.

[0060] In some embodiments of the present invention, the weight of the plug 42 is greater than the weight of the sealing member 43 so that the sealing member 43 is suitable for moving toward a second position.

[0061] The plug 42 is in contact with the fluid passage 29 by the contact rib 421, and the sealing member 43 is provided on the steam generation chamber 11 side of the fluid passage 29. By making the weight of the plug 42 greater than the weight of the sealing member 43, the center of gravity of the steam valve 40 can be positioned on the exhaust port side of the fluid passage 29. After the steam humidifier 100 tips over, the plug 42 can move the sealing member 43 to a second position, allowing the steam valve 40 to move to the second position under the influence of gravity, thereby achieving sealing of the fluid passage 29 by the steam valve 40, which is advantageous in improving the safety of use of the steam humidifier 100.

[0062] Referring to Figures 1 and 2, in some embodiments of the present invention, at least the portion of the lid assembly 2 that defines the fluid passage 29 extends inclined toward the steam generating chamber 11.

[0063] For example, a plate is provided within the lid assembly 2, and the orthographic projection surface of the plate can block a portion of the orthographic projection surface of the steam generation chamber 11 along the central axis direction of the fluid passage 29. This plate limits the fluid passage 29, and the plate extends from the outer circumference, gradually sloping toward the steam generation chamber 11, so that the fluid passage 29 is located at the lowest point of the plate. This allows condensed water to collect in the fluid passage 29 and flow into the steam generation chamber 11 through the fluid passage 29, reducing the risk of condensed water accumulating within the lid assembly 2 and improving the effect of condensed water recirculation.

[0064] Preferably, the intermediate portion of the plate body closest to the fluid passage 29 may extend toward the steam generation chamber 11. Specifically, the size of the portion of the lid assembly 2 that defines the fluid passage 29 and the size of the portion that extends toward the steam generation chamber 11 are not limited here, as long as the recirculation effect of condensate is ensured and the usage requirements are met.

[0065] Referring to Figures 7 and 8, in some embodiments of the present invention, the plug 42 is snap-engaged with the sealing member 43.

[0066] For example, an engagement hole 431 is formed in the sealing member 43 and penetrates it, a water reservoir groove 41 is provided surrounding the engagement hole 431 along its circumferential direction, and a locking connection portion 422 is provided at one end of the plug 42 closest to the sealing member 43. The locking connection portion 422 is inserted into the engagement hole 431 and locked and connected to the sealing member 43, thereby achieving a snap engagement between the plug 42 and the sealing member 43, making it convenient to attach and detach the plug 42 and the sealing member 43.

[0067] The locking connection portion 422 can be formed as two hooks facing away from each other and spaced apart, and the maximum distance between the two hooks can be greater than the diameter of the engagement hole 431. During the snap engagement of the locking connection portion 422 and the sealing member 43, the hole wall of the engagement hole 431 presses the two hooks together, deforming them toward each other. After the locking connection portion 422 is fitted into the sealing member 43, at least a portion of the locking connection portion 422 (e.g., the hook body portion of the hook) extends out of the engagement hole 431 to recover its deformation, and the locking connection portion 422 locks into and fits into the sealing member 43, achieving snap engagement between the plug 42 and the sealing member 43.

[0068] To ensure clarity, the plug 42 and the sealing member 43 may achieve snap engagement in other ways, and the specific form of snap engagement between the plug 42 and the sealing member 43 can be determined in actual manufacturing and production, and is not specifically limited herein.

[0069] Selectively, the sealing member 43 and the plug 42 may be molded independently, and in the process of mounting the lid assembly 2, the sealing member 43 may first be attached to the steam generation chamber 11 side of the fluid passage 29, and then the plug 42 and the sealing member 43 may be snap-engaged; or a positioning mounting structure may be provided on the lid assembly 2, and the sealing member 43 may first be attached to the lid assembly 2 with the positioning mounting structure, and then the plug 42 and the sealing member 43 may be snap-engaged; or the sealing member 43 may be integrally molded with the lid assembly 2, which is advantageous in simplifying the mounting process of the lid assembly 2 and improving the mounting efficiency of the lid assembly 2.

[0070] Referring to Figures 1 and 2, in some embodiments of the present invention, the portion of the lid assembly 2 surrounding the fluid passage 29 is bent toward the steam generating chamber 11 to define a first end 291, which contacts and abuts against the steam valve 40, which is advantageous for improving the sealing effect of the fluid passage 29 by the steam valve 40.

[0071] The portion of the lid assembly 2 surrounding the fluid passage 29 is bent and inclined toward the steam generating chamber 11, defining the fluid passage 29 with a tapered cross-section. The cross-section of the plug 42 is tapered along the direction in which the lid assembly 2 extends toward the steam generating chamber 11. When the steam humidifier 100 tips over, the inner wall surface of the fluid passage 29 with a tapered cross-section can guide the plug 42, causing it to move toward the steam generating chamber 11. At the same time, the plug 42 moves toward the ground, and the plug 42 can interlock with the synchronous movement of the sealing member 43, causing the sealing member 43 to contact and abut against the first end 291, thereby sealing the fluid passage 29.

[0072] When the steam humidifier is raised to its normal upright position, the steam valve 40 moves towards the steam generation chamber 11 under the influence of gravity. When the steam valve 40 moves to the first position, the steam valve 40 and the first end 291 are spaced apart, the fluid passage 29 and the steam generation chamber 11 are in communication, and condensed water can flow into the steam generation chamber 11.

[0073] Referring to Figures 1 and 9, in some embodiments of the present invention, the lid assembly 2 includes an upper lid chamber 2421 that communicates with a steam generating chamber 11, a steam outlet 21 is provided on the top wall of the upper lid chamber 2421, and a fluid passage 29 is provided on the bottom wall of the upper lid chamber 2421.

[0074] Furthermore, "the top wall of the upper lid chamber 2421" refers to the wall surface of the upper lid chamber 2421 that is farther from the steam generation chamber 11, and "the bottom wall of the upper lid chamber 2421" refers to the wall surface of the upper lid chamber 2421 that is closer to the steam generation chamber 11.

[0075] An upper lid chamber 2421 is formed on the side of the lid assembly 2 furthest from the steam generation chamber 11. The upper lid chamber 2421 is connected to the steam generation chamber 11 by an exhaust port and a fluid passage 29. Steam generated in the steam generation chamber 11 can flow into the upper lid chamber 2421 through the exhaust port, and the steam can flow within the upper lid chamber 2421. During the steam flow process, some of the steam condenses into water due to a decrease in temperature and pressure. This condensed water flows back into the steam generation chamber 11 through the fluid passage 29, and can condense on any wall surface of the upper lid chamber 2421. However, considering that the condensed water flows to the bottom wall of the upper lid chamber 2421 under the influence of gravity, providing a fluid passage 29 on the bottom wall of the upper lid chamber 2421 is advantageous in enhancing the recirculation effect of the condensed water and reducing the possibility of condensed water accumulating within the upper lid chamber 2421.

[0076] The upper lid chamber 2421 is connected to the outside space via a steam outlet 21 located on its top wall. The steam from other parts (i.e., some of the steam that has not been converted into condensed water) is discharged to the outside space via the steam outlet 21, humidifying the outside space and realizing the humidification function of the steam humidifier 100, thereby adjusting the humidity of the outside space.

[0077] By providing a steam outlet 21 on the top wall of the upper lid chamber 2421, steam can flow sufficiently within the upper lid chamber 2421 after entering it from the exhaust port, extending the steam flow path, enhancing the cooling effect during the steam flow process, and reducing the risk of the steam discharged from the steam humidifier 100 being too hot and causing burns to the user.

[0078] The term "external space" refers to the space outside the steam humidifier 100, and may be an outdoor space or an indoor space.

[0079] Referring to Figures 1 and 9, in some embodiments of the present invention, one side of the steam generation chamber 11 is open, the lid assembly 2 is provided at the open end of the steam generation chamber 11 and can seal the open end of the steam generation chamber 11, which is advantageous in preventing impurities such as dust from falling into the steam generation chamber 11 and contaminating the water inside the steam generation chamber 11.

[0080] The lid assembly 2 comprises a sealing lid 241 and an upper lid plate 242, the upper lid plate 242 being located on the side of the sealing lid 241 furthest from the steam generating chamber 11, the sealing lid 241 being located on the steam generating body 1 to seal the steam generating chamber 11 and at the open end of the steam generating chamber 11, and a communication port 2414 being provided in the sealing lid 241, referring to Figure 2, the communication port 2414 can connect the fluid passage 29 and the steam generating chamber 11, and condensed water can flow from the fluid passage 29 into the water reservoir groove 41 and then further into the steam generating chamber 11 through the communication port 2414.

[0081] The sealing lid 241 is provided with a ring-shaped projection 2415 that surrounds and communicates with the communication opening 2414. The ring-shaped projection 2415 protrudes from the sealing lid 241 toward the upper lid plate 242 and can abut against and be fitted to the upper lid plate 242. The ring-shaped projection 2415 is used to limit the flow range of condensed water and prevent condensed water from flowing over a wide area of ​​the sealing lid 241 and affecting the operation of other components on the sealing lid 241.

[0082] Referring to Figure 1, a sealing portion 2416 is provided between the ring-shaped projection 2415 and the upper lid plate 242. The sealing portion 2416 can seal the space between the ring-shaped projection 2415 and the upper lid plate 242, preventing condensed water from overflowing from the space between the ring-shaped projection 2415 and the upper lid plate 242 if there is too much condensed water, and improving the sealing effect between the ring-shaped projection 2415 and the upper lid plate 242.

[0083] Referring to Figures 1 and 9, the upper lid plate 242 is provided with an upper lid chamber 2421, which is recessed on the side approaching the steam generation chamber 11, and the fluid passage 29 is provided in the bottom wall of the upper lid chamber 2421, and the fluid passage 29 is located inside the ring-shaped projection 2415, so that the condensed water falls within the range limited by the ring-shaped projection 2415, and the ring-shaped projection 2415 is provided so that it surrounds the communication port 2414, so the fluid passage 29 is located inside the ring-shaped projection 2415, which is advantageous in ensuring that the condensed water flows smoothly into the communication port 2414, and thereby is advantageous in guaranteeing the effect of the condensed water flowing into the steam generation chamber 11.

[0084] Referring to Figures 1 and 9, in some embodiments of the present invention, the ring-shaped projection 2415, the sealing lid 241, and the upper lid plate 242 together define an airflow cavity 60. If the pressure in the steam generation chamber 11 becomes too high, the airflow cavity 60 can connect the steam generation chamber 11 to the upper lid chamber 2421. The steam generation chamber 11 can then release pressure to the outside space through the airflow cavity 60 and the upper lid chamber 2421, preventing safety concerns due to excessive pressure in the steam generation chamber 11 and improving the safety of use of the steam humidifier 100.

[0085] As shown in Figure 9, in some embodiments of the present invention, the upper lid plate 242 is provided with a lid body 2424, the lid body 2424 covers the open end of the upper lid chamber 2421 and can be formed as a grill, the grill is provided with a plurality of spaced partition ribs, steam outlets 21 are defined between adjacent partition ribs, and by providing a plurality of steam outlets 21, it is advantageous to improve the steam discharge efficiency from the steam humidifier 100, and thereby advantageous to improve the humidification efficiency of the steam humidifier 100.

[0086] Referring to Figures 2 and 5, in some embodiments of the present invention, the steam humidifier 100 includes a first state and a second state, in which both the exhaust port and the fluid passage 29 are opened to discharge steam.

[0087] As shown in Figure 2, immediately after steam is generated in the first state of the steam humidifier 100, the steam is discharged along the exhaust port, and the amount of condensed water from the steam in the first state is small, so the liquid surface of the condensed water that flows into the water reservoir groove 41 is insufficient to contact the first end 291. That is, at this time, the liquid surface in the water reservoir groove 41 does not seal the fluid passage 29, and the fluid passage 29 is in an open state, allowing some of the steam to be discharged through the fluid passage 29.

[0088] As shown in Figure 5, in the second state, the liquid level in the water reservoir groove 41 is higher than the first end 291 so as to seal the fluid passage 29, and the exhaust port is opened to discharge steam.

[0089] During the operation of the steam humidifier 100, condensed water from the condensation of steam constantly collects in the water reservoir groove 41, and the liquid level of the condensed water in the water reservoir groove 41 gradually rises toward the first end 291. When the liquid level is higher than the first end 291 (which can also be understood as the first end 291 being submerged below the liquid level), the condensed water in the water reservoir groove 41 seals the fluid passage 29, preventing steam from being discharged through the fluid passage 29. Instead, the steam is discharged independently from the steam humidifier 100 through the exhaust port, and at this time, the steam humidifier 100 is in the second state.

[0090] After the steam humidifier 100 is shut down, the air pressure inside the steam humidifier 100 decreases, the liquid level in the water reservoir groove 41 decreases, and if the liquid level falls below the first end 291, then when the steam humidifier 100 is turned on again and generates steam, some of the steam may still flow out through the fluid passage 29.

[0091] Referring to Figures 1, 2, and 9, the steam valve 40 for a liquid heating vessel according to an embodiment of the present invention is such that the liquid heating vessel is equipped with a fluid passage 29, steam can be discharged from the steam humidifier 100 through the fluid passage 29, and condensed water obtained from the steam can be recirculated through the fluid passage 29.

[0092] The liquid heating container may be an electric kettle, electric water bottle, wearable aroma diffuser, humidifier, or steamer.

[0093] Referring to Figures 1, 2 and 6, the steam valve 40 is inserted into the fluid passage 29, and the steam valve 40 is equipped with a plug 42, the plug 42 is suitable for insertion into the fluid passage 29, and a contact rib 421 is provided on at least one of the plug 42 and the fluid passage 29, defining a recirculation passage 50 between the adjacent contact rib 421 and the other wall surface.

[0094] For example, a plug 42 may be inserted into a fluid passage 29, and a plurality of spaced abutment ribs 421 may be formed on the outer circumferential wall of the plug 42, and the abutment ribs 421 may be supported on the inner circumferential wall of the fluid passage 29 such that there is a gap between the outer circumferential wall of the plug 42 and the inner circumferential wall of the fluid passage 29, thereby defining a recirculation passage 50 by the plurality of abutment ribs 421, the outer circumferential wall of the plug 42 and the inner circumferential wall of the fluid passage 29, thereby preventing the plug 42 from sealing the fluid passage 29, and allowing both steam and condensate to flow through the recirculation passage 50.

[0095] Alternatively, a plurality of contact ribs 421 can be formed at intervals on the inner circumferential wall of the fluid passage 29. When the plug 42 is inserted into the fluid passage 29, the contact ribs 421 can be supported on the outer circumferential wall of the plug 42 such that there is a gap between the outer circumferential wall of the plug 42 and the inner circumferential wall of the fluid passage 29. The plurality of contact ribs 421, the outer circumferential wall of the plug 42, and the inner circumferential wall of the fluid passage 29 define the recirculation passage 50, preventing the plug 42 from sealing the fluid passage 29 by contact between the outer circumferential wall of the plug 42 and the inner circumferential wall of the fluid passage 29, thereby allowing both steam and condensed water to flow through the recirculation passage 50.

[0096] Selectively, the contact rib 421 may be formed as a convex rib portion extending along the circumferential direction of the plug 42 or fluid passage 29, the contact rib 421 may be formed as a rib bar extending along the direction of liquid flow, or the contact rib 421 may be configured as a convex point.

[0097] To ensure clarity, the specific placement position and method of the contact rib 421 can be determined according to actual production requirements and are not specifically limited therein.

[0098] Referring to Figures 1, 2, and 6, the steam valve 40 further comprises a sealing member 43, the sealing member 43 is provided on the plug 42 and is located on the opposite side of the fluid passage 29 from the plug 42, the sealing member 43 is provided with a water reservoir groove 41 that opens toward the plug 42, and the water reservoir groove 41 is opposite the fluid passage 29 and communicates with the recirculation passage 50, so that condensed water can flow from the recirculation passage 50 into the water reservoir groove 41, the water reservoir groove 41 has a function of receiving the liquid recirculated from the recirculation passage 50 and the condensed water can collect in the water reservoir groove 41, thus realizing the collection of condensed water.

[0099] In the embodiment of the present invention, the steam valve 40 for a liquid heating container is inserted into the fluid passage 29, and a water reservoir groove 41 opening toward the plug 42 is provided in the sealing member 43. This allows condensed water to flow into the water reservoir groove 41 via the fluid passage 29, thereby realizing the condensed water collection function of the steam valve 40.

[0100] Referring to Figures 1 to 4, in some embodiments of the present invention, the weight of the plug 42 is greater than the weight of the sealing member 43, such that the center of gravity of the steam valve 40 is located closer to the plug 42 of the fluid passage 29. After the steam humidifier 100 tips over, the plug 42 can move the sealing member 43 toward the plug 42, that is, the plug 42 can move the sealing member 42 toward the second position described above. This enables the steam valve 40 to move to the second position under the action of gravity. When the sealing member 43 abuts against and fits into the fluid passage 29, the sealing member 43 closes the fluid passage 29, preventing high-temperature water in the steam humidifier 100 from leaking from the fluid passage 29, thereby improving the safety of the steam humidifier 100.

[0101] Referring to Figures 7 and 8, in some embodiments of the present invention, the plug 42 and the sealing member 43 are snap-engaged.

[0102] For example, an engagement hole 431 is formed in the sealing member 43 and penetrates it, a water reservoir groove 41 is provided surrounding the engagement hole 431 along its circumferential direction, and a locking connection portion 422 is provided at one end of the plug 42 closest to the sealing member 43. The locking connection portion 422 is inserted into the engagement hole 431 and locked and connected to the sealing member 43, thereby achieving a snap engagement between the plug 42 and the sealing member 43, making it convenient to attach and detach the plug 42 and the sealing member 43.

[0103] The locking connection portion 422 can be formed as two hooks facing away from each other and spaced apart, and the maximum distance between the two hooks can be greater than the diameter of the engagement hole 431. During the snap engagement of the locking connection portion 422 and the sealing member 43, the hole wall of the engagement hole 431 presses the two hooks together, deforming them toward each other. After the locking connection portion 422 is fitted into the sealing member 43, at least a portion of the locking connection portion 422 (e.g., the hook body portion of the hook) extends out of the engagement hole 431 to recover its deformation, and the locking connection portion 422 locks into and fits into the sealing member 43, achieving snap engagement between the plug 42 and the sealing member 43.

[0104] To ensure clarity, the plug 42 and the sealing member 43 may achieve snap engagement in other ways, and the specific form of snap engagement between the plug 42 and the sealing member 43 can be determined according to actual production requirements and is not specifically limited herein.

[0105] As shown in Figure 2, in some embodiments of the present invention, the outer periphery of the plug 42 has the effect of guiding condensed water, as the cross-sectional area of ​​at least a portion of the plug 42 gradually decreases in the direction toward the sealing member 43, thereby facilitating the flow of condensed water into the water reservoir groove 41.

[0106] Selectively, the plug 42 may be formed such that its overall cross-sectional area gradually decreases toward the sealing member 43, or the cross-sectional area on one side away from the sealing member 43 gradually decreases toward the sealing member 43. The specific configuration of the plug 42 can be determined according to actual production requirements and is not specifically limited herein.

[0107] As shown in Figure 2, in some embodiments of the present invention, the orthographic outer edge of the sealing member 43 of the plug 42 does not exceed the outer edge of the water reservoir groove 41, that is, the orthographic surface of the water reservoir groove 41 is large, the volume of the water reservoir groove 41 is large, the capacity of the water reservoir groove 41 to contain condensed water is increased, and the possibility of condensed water overflowing from the water reservoir groove 41 is reduced.

[0108] Furthermore, "orthographic projection of the plug 42 on the sealing member 43" refers to the projection in the direction in which the plug 42 is facing the sealing member 43.

[0109] Selectively, the orthographic outer edge of the sealing member 43 of the plug 42 can be flush with the outer edge of the water reservoir groove 41, or the orthographic outer edge of the sealing member 43 of the plug 42 can be inside the outer edge of the water reservoir groove 41. Specifically, the arrangement of the plug 42 and the water reservoir groove 41 can be determined according to actual production requirements and is not specifically limited thereto.

[0110] The liquid heating vessel according to an embodiment of the present invention comprises a steam generating chamber 11, a lid assembly 2, and a steam valve 40. The liquid heating vessel is the steam humidifier 100 described above, and the steam valve 40 may be the steam valve 40 described above. A fluid passage 29 is provided in the lid assembly 2, the steam valve 40 is provided in the lid assembly 2, and the fluid passage 29 communicates with the steam generating chamber 11.

[0111] The steam generation chamber 11 is used to hold water, and the steam generation body 1 can generate steam in the steam generation chamber 11 by heating the water to a boil. The lid assembly 2 is provided with a fluid passage 29 that communicates with the steam generation chamber 11, and the liquid (i.e., condensed water) from the condensation of steam can flow back into the steam generation chamber 11 through the fluid passage 29. A steam valve 40 is also provided in the lid assembly 2, which is convenient for inserting into the fluid passage 29. A water reservoir groove 41 is convenient for receiving the condensed water that has been returned through the return passage 50. When the water reservoir groove 41 is filled with condensed water, the condensed water can flow back into the steam generation chamber 11, thereby enabling the reuse of condensed water.

[0112] The above-mentioned steam valve 40 is provided in the liquid heating container, and the steam valve 40 is inserted into the fluid passage 29. In addition, a water reservoir groove 41 opening toward the plug 42 is provided in the sealing member 43, so that condensed water can flow into the water reservoir groove 41 via the fluid passage 29, thereby realizing the function of collecting condensed water by the steam valve 40.

[0113] Referring to Figures 2 and 5, in some embodiments of the present invention, the lower end of the fluid passage 29 extends below the highest wall surface of the water reservoir groove 41.

[0114] Furthermore, "the lower end of the fluid passage 29" refers to the end of the fluid passage 29 closest to the steam generation chamber 11, and "the highest wall surface of the water reservoir groove 41" refers to the wall surface of the water reservoir groove 41 furthest from the steam generation chamber 11.

[0115] The lower end of the fluid passage 29 extends below the highest wall surface of the water reservoir groove 41, which is advantageous for enhancing the guiding effect of the fluid passage 29 on condensed water. Furthermore, when the liquid level in the water reservoir groove 41 exceeds the lower end of the fluid passage 29, the condensed water can achieve a liquid seal on the fluid passage 29, reducing the risk of steam leaking from the fluid passage 29.

[0116] In some embodiments of the present invention, the liquid heating container includes a first state, a second state, and a third state.

[0117] Referring to Figures 1 and 2, in the first state, the fluid passage 29 is opened and steam is discharged, that is, immediately after steam is generated in the first state, the liquid heating container has little condensed water from the steam, and the liquid level of the condensed water that has flowed into the water reservoir groove 41 is insufficient to contact the lower end of the fluid passage 29, that is, at this time the liquid level in the water reservoir groove 41 does not seal the fluid passage 29, and at this time the fluid passage 29 is in an open state, and some steam can be discharged through the fluid passage 29.

[0118] As shown in Figure 5, in the second state, the liquid level in the water reservoir groove 41 is higher than the lower end of the fluid passage 29, so as to seal the fluid passage 29.

[0119] During the operation of the liquid heating vessel, condensed water from the condensation of steam constantly collects in the water reservoir groove 41, and the liquid level of the condensed water in the water reservoir groove 41 gradually rises toward the lower end of the fluid passage 29 (i.e., the first end 291). When the liquid level comes into contact with the first end 291 (which can also be understood as the first end 291 being submerged below the liquid level), the steam humidifier 100 is in the second state, where the condensed water in the water reservoir groove 41 seals the fluid passage 29, preventing steam from being discharged through the fluid passage 29 and reducing steam leakage.

[0120] In both the first and second states, the liquid heating container is in a normal upright position.

[0121] Referring to Figures 3 and 4, in the third state, the lower end of the fluid passage 29 is in contact with the bottom wall of the water reservoir groove 41.

[0122] Furthermore, "the bottom wall of the water reservoir groove 41" refers to the wall surface on the side of the water reservoir groove 41 that is closest to the steam generation chamber 11.

[0123] After the liquid heating container tips over, under the influence of gravity, the plug 42 moves the sealing member 43 toward the fluid passage 29, and the steam valve 40 moves until the bottom wall of the water reservoir groove 41 contacts and abuts against the lower end of the fluid passage 29, at which point the liquid heating container is in the third state, at which point the sealing member 43 seals the fluid passage 29, preventing the high-temperature water in the liquid heating container from leaking out of the fluid passage 29.

[0124] As a result, the steam valve 40 can seal the flow passage 29 after the liquid heating container has tipped over, providing a leak prevention function when the liquid heating container tips over, which is advantageous in improving the safety of using the liquid heating container.
