[0052] Reference below Figures 1-15 A steam humidifying device 100 according to an embodiment of the present invention is described.

[0053] Combine Figures 1 to 4 According to an embodiment of the present invention, the steam humidifying device 100 includes: a steam generating body 1, a cover assembly 2 and a rotating assembly 3. The steam generating body 1 is formed with a steam generating chamber 11, the cover assembly 2 is arranged on the steam generating body 1, the cover assembly 2 is provided with a steam outlet 21, the rotating assembly 3 is rotatably provided on the steam generating body 1 and / or the cover assembly 2, a steam channel 31 is provided in the rotating assembly 3, and the steam channel 31 is provided with an air inlet 311 connected to the steam generating chamber 11 and an outlet end 312 connected to the steam outlet 21.

[0054] Combine Figure 1 and Figure 2 The steam generating chamber 11 formed by the steam generating body 1 is used to hold water, and the steam generating body 1 can heat and evaporate water to generate steam. A steam channel 31 is provided in the rotating component 3. The air inlet 311 of the steam channel 31 is connected to the steam generating chamber 11, and the outlet end 312 of the steam channel 31 is connected to the steam outlet 21. Steam flows from the steam generating chamber 11 through the air inlet 311 into the steam channel 31.

[0055] Combine Figure 2 and Figure 3 , taking into account that the flow rate of steam may be reduced due to the existence of resistance when steam passes through the steam channel 31, the cover assembly 2 of the present application is also provided with a guide channel 23, and the guide channel 23 is provided with an air outlet 24221. The air outlet 24221 is spaced apart and connected to the steam outlet 21. At the same time, the steam channel 31 is provided with an outlet end 312 connected to the guide channel 23. The steam flowing into the steam channel 31 can flow into the guide channel 23 through the outlet end 312. The guide channel 23 can limit the flow path of the steam, which is conducive to increasing the flow rate of the steam and reducing the condensation of the steam. The accelerated steam can further flow from the air outlet 24221 to the steam outlet 21, and the steam can be discharged from the steam humidification device 100 into the external space through the steam outlet 21, thereby realizing the humidification function of the steam humidification device 100 to improve the humidity of the external space.

[0056] It should be noted that the “external space” refers to the space outside the steam humidification device 100 , which can be an indoor space or an outdoor space.

[0057] Combine Figures 2 to 4 The rotating assembly 3 is provided with a counterweight portion 32 , and the rotating assembly 3 has a first state. In the first state, the counterweight portion 32 is located at the lower end of the rotating assembly 3 and the air inlet 311 is located in the upper space of the steam humidifying device 100 .

[0058] When the steam humidifying device 100 falls over, since the rotating assembly 3 is provided with a counterweight portion 32, the rotating assembly 3 rotates to the first state under the gravity of the counterweight portion 32 itself. Figure 4 At this time, the counterweight part 32 rotates to the lower space of the steam generating device, and the air inlet 311 rotates to the upper space of the steam humidifying device 100, which is beneficial to prevent the high-temperature water in the steam generating chamber 11 from flowing into the steam channel 31 through the air inlet 311 and further leaking through the steam outlet 21, that is, realizing the dumping anti-leakage function of the steam humidifying device 100, which is beneficial to improving the safety of use of the steam humidifying device 100.

[0059] It should be noted that the above-mentioned "up" and "down" refer to the up and down directions of the steam humidification device 100 after it is tilted. For specific directions, please refer to Figure 4 shown.

[0060] Optionally, the rotating component 3 can be rotatably set on the steam generating body 1, or the rotating component 3 can be rotatably set on the cover component 2, or the rotating component 3 can be rotatably set on the steam generating body 1 and the cover component 2 at the same time. The specific setting position of the rotating component 3 can be determined according to actual production requirements and is not specifically limited here, as long as the assembly stability of the rotating component 3 is guaranteed.

[0061] According to the steam humidification device 100 of the embodiment of the present invention, by setting a rotating component 3, when the steam humidification device 100 falls over, the rotating component 3 can rotate under the action of the counterweight part 32, so that the air inlet 311 rotates to the upper space of the steam humidification device 100, which is beneficial to prevent the leakage of high-temperature water in the steam generating chamber 11, realizes the tipping anti-leakage function of the steam humidification device 100, and effectively improves the safety of use of the steam humidification device 100. By setting a guide channel 23 in the cover component 2, it is beneficial to increase the flow rate of steam, reduce the condensation of steam, and improve the humidification efficiency of the steam humidification device 100.

[0062] The rotating assembly 3 may be formed as a plastic part, which is beneficial to reducing the material cost of the rotating assembly 3 and thus beneficial to reducing the production cost of the steam humidification device 100 .

[0063] In some embodiments of the present invention, the opening area of the air outlet 24221 is smaller than the minimum flow area of the guide channel 23. In the process of steam flowing from the guide channel 23 to the air outlet 24221, since the opening area of the air outlet 24221 is smaller than the minimum flow area of the guide channel 23, the steam will be further accelerated when passing through the air outlet 24221, which is beneficial to further reduce the condensation of steam and improve the humidification effect of the steam humidification device 100.

[0064] like Figure 11 In some embodiments of the present invention, the flow area of at least a portion of the guide channel 23 gradually decreases in the direction toward the air outlet 24221 .

[0065] Exemplarily, the flow area of a portion of the guide channel 23 close to the air outlet 24221 gradually decreases in the direction toward the air outlet 24221, or the flow area of the entire guide channel 23 gradually decreases in the direction toward the air outlet 24221, so that the guide channel 23 can further accelerate the steam and reduce the condensation of steam.

[0066] It is understandable that the specific structure of the guide channel 23 can be determined according to actual production requirements and is not specifically limited here.

[0067] Combine Figure 3 and Figure 11 In some embodiments of the present invention, the outlet end 312 is located at one end of the guide channel 23, and the other end of the guide channel 23 extends linearly toward the air outlet 24221, that is, in the projection direction of the rotation axis of the rotating component 3, the guide channel 23 extends linearly from the outlet end 312 to the air outlet 24221 side, so as to shorten the distance between the outlet end 312 and the air outlet 24221, thereby shortening the flow distance of the steam in the guide channel 23, avoiding large steam loss due to the bending of the steam flow path, which is beneficial to improving the efficiency of steam outflow and reducing steam condensation.

[0068] like Figure 4 As shown, in some embodiments of the present invention, in the first state, the air inlet 311 opens upward.

[0069] When the steam humidifier 100 falls over, the rotating component 3 rotates under the gravity of the counterweight part 32, and the rotating component 3 rotates to the first state. At this time, the counterweight part 32 is located in the lower space of the steam humidifier 100, and the air inlet 311 is located in the upper space of the steam humidifier 100, and the air inlet 311 is open upward and higher than the height of the water surface P in the steam generating chamber 11, so as to effectively prevent the high-temperature water in the steam generating chamber 11 from flowing into the steam channel 31 through the air inlet 311, thereby preventing the high-temperature water from leaking and scalding the user when the steam humidifier 100 falls over, thereby effectively improving the safety of use of the steam humidifier 100.

[0070] Combine Figures 5 to 7 In some embodiments of the present invention, the rotating assembly 3 includes: a rotating shaft 33, a first rod segment 34 and a second rod segment 35. The rotating shaft 33 is rotatably provided on the cover assembly 2. A first extension segment 313 of the steam channel 31 is formed in the rotating shaft 33. The first extension segment 313 is connected to the steam outlet 21. The first rod segment 34 extends along the first direction and is provided on the rotating shaft 33. The first rod segment 34 forms a second extension segment 314 of the steam channel 31 which is arranged to pass through along the first direction. The second extension segment 314 is respectively connected to the steam generating chamber 11 and the second extension segment 314. The second rod segment 35 extends along the first direction and is provided on the rotating shaft 33.

[0071] Combine Figures 2 to 7 The first rod segment 34 and the second rod segment 35 are respectively arranged on the rotating shaft 33, so that the first rod segment 34 and the second rod segment 35 can rotate in the cover assembly 2 through the rotating shaft 33, wherein a second extension segment 314 of the steam channel 31 is formed on the first rod segment 34, and an air inlet 311 connected to the steam generating chamber 11 is formed at one end of the first rod segment 34 away from the rotating shaft 33 in the first direction, and the second extension segment 314 is connected to the first extension segment 313 of the steam channel 31 in the rotating shaft 33 at one end away from the second extension segment 314 in the first direction, and an outlet end 312 connected to the steam outlet 21 is formed at one end of the second extension segment 314 away from the second extension segment 314.

[0072] Combine Figure 2 and Figure 3 When steam is generated in the steam generating chamber 11, the steam passes through the air inlet 311, the second extension section 314, the first extension section 313, the outlet end 312 in sequence and flows to the steam outlet 21. The steam is discharged from the steam humidifying device 100 through the steam outlet 21 to realize the humidifying function of the steam humidifying device 100. In the process of steam discharge, due to the long flow path of the steam, it is beneficial to reduce the temperature of the steam discharged from the steam humidifying device 100, which is beneficial to prevent the high-temperature steam from scalding the user.

[0073] Combine Figures 2 to 7 A counterweight portion 32 is provided at one end of the second rod segment 35 away from the rotation axis 33 .

[0074] When the steam humidification device 100 tips over, the counterweight part 32 has a tendency to rotate toward the lower space of the steam humidification device 100 under the action of its own gravity. The counterweight part 32 can drive the rotating shaft 33 to rotate in the cover assembly 2 through the second rod segment 35. The rotating shaft 33 drives the first rod segment 34 to rotate while rotating, so that the counterweight part 32 can be rotated to the lower space of the steam humidification device 100 and the air inlet 311 can be rotated to the upper space of the steam humidification device 100, which is beneficial to prevent the high-temperature water in the steam generating chamber 11 from flowing into the steam channel 31 through the air inlet 311, thereby realizing the anti-leakage function of the steam humidification device 100 when it tips over.

[0075] During the tipping leakage test on the steam humidification device 100 of the present application, when the steam humidification device 100 tipped over, the leakage of high-temperature water within 10 seconds can be less than 50 ml. Therefore, the steam humidification device 100 of the present application has a good tipping and side leakage prevention effect, effectively improving the safety of use of the steam humidification device 100.

[0076] The counterweight 32 is arranged at the end of the second rod section 35 away from the rotating shaft 33 so that the counterweight 32 drives the rotating shaft 33 to rotate through the second rod section 35 , which is beneficial to improving the driving effect of the counterweight 32 on the rotating component 3 .

[0077] Combine Figure 5 and Figure 6 In some embodiments of the present invention, the first rod segment 34 and the second rod segment 35 are symmetrically arranged relative to the central axis of the rotating shaft 33, so that the air inlet 311 and the counterweight portion 32 can be respectively located on both sides of the rotating shaft 33 in the first direction, which is conducive to ensuring that when the counterweight portion 32 rotates to the lower space of the steam humidification device 100, the air inlet 311 is located in the upper space of the steam humidification device 100, thereby facilitating the dumping and leakage prevention function of the steam humidification device 100 through the rotating component 3 and the counterweight portion 32.

[0078] Combine Figure 5 and Figure 6 In some embodiments of the present invention, a reinforcement portion 351 is formed on the second rod segment 35, and the reinforcement portion 351 is used to improve the structural strength of the second rod segment 35. The reinforcement portion 351 is located between the counterweight portion 32 and the rotating shaft 33 on the second rod segment 35 to prevent the second rod segment 35 from being deformed due to the counterweight portion 32 being provided at the end of the second rod segment 35 away from the rotating shaft 33, which is conducive to ensuring the driving effect of the counterweight portion 32 on the rotating component 3.

[0079] For example, in combination Figure 5 and Figure 6 The reinforcement portion 351 can be formed as a groove body that is recessed from one end surface of the second rod segment 35 to the other end surface in a direction parallel to the central axis of the rotating shaft 33, so as to improve the structural strength of the second rod segment 35 and at the same time help reduce the material cost of the rotating component 3.

[0080] Of course, it is understandable that the reinforcement part 351 can also be configured as other structural forms, such as: reinforcing ribs, etc. The specific structural form of the reinforcement part 351 can be determined according to actual production requirements and is not specifically limited here, as long as the reinforcement part 351 ensures the reinforcing effect on the second rod segment 35.

[0081] Combine Figure 2 and Figure 3 In some embodiments of the present invention, a first space 22 is formed in the cover assembly 2 , and the first space 22 is communicated with the steam generating chamber 11 .

[0082] The first space 22 and the guide channel 23 are arranged in a direction parallel to the central axis of the rotating shaft 33, and the first space 22 is arranged close to the steam generating chamber 11 relative to the guide channel 23, so that the first space 22 is connected to the steam generating chamber 11, and the steam generated in the steam generating chamber 11 can flow from the steam generating chamber 11 into the first space 22.

[0083] Among them, combined Figures 2 to 4 The rotating assembly 3 is rotatably disposed on the cover assembly 2 and is located in the first space 22 , and the air inlet 311 is communicated with the first space 22 .

[0084] The second extension section 314 extends along the first direction, and the first space 22 is connected to the air inlet 311 of the steam channel 31. After the steam in the steam generating chamber 11 flows into the first space 22, it can flow into the steam channel 31 through the air inlet 311. The first extension section 313 extends along a direction parallel to the central axis of the rotating shaft 33, and the outlet end 312 is located on the side of the first extension section 313 close to the guide channel 23, so that the outlet end 312 is connected to the guide channel 23. The steam flowing into the steam channel 31 can be discharged into the guide channel 23 through the outlet end 312, and further discharged from the steam humidification device 100 through the steam outlet 21.

[0085] Combine Figure 3 as well as Figures 8 to 10 The cover assembly 2 includes: a cover body 24, a guide channel 23 is provided in the cover body 24, and the cover body 24 is provided with a steam outlet 21, the guide channel 23 is connected to the external space through the steam outlet 21, so that the steam flowing into the guide channel 23 can be discharged from the steam humidification device 100 into the external space through the steam outlet 21, thereby humidifying the external space.

[0086] Combine Figure 3 as well as Figures 8 to 10 The cover assembly 2 also includes a shielding cover 25, which is arranged on the side of the cover body 24 facing the steam generating body 1. A first space 22 is defined between the shielding cover 25 and the cover body 24. The first space 22 can be used to arrange the rotating assembly 3. There is no need to design a separate installation space for the rotating assembly 3, which is beneficial to improving the space utilization on the cover assembly 2, thereby improving the integration of the cover assembly 2, and the shielding cover 25 can shield the structure inside the first space 22, which is beneficial to improving the aesthetics of the cover assembly 2.

[0087] Reference Figure 10 The shielding cover 25 is provided with an air vent 251 connecting the first space 22 and the steam generating chamber 11. The air vent 251 is arranged through the shielding cover 25 in a direction parallel to the central axis of the rotating shaft 33. The steam in the steam generating chamber 11 can flow into the first space 22 through the air vent 251, and then the steam can flow into the guide channel 23 through the steam channel 31, and further be discharged from the steam humidification device 100 through the steam outlet 21.

[0088] Among them, multiple air holes 251 can be arranged at intervals. Multiple air holes 251 are beneficial to improving the efficiency of the steam in the steam generating chamber 11 flowing into the first space 22, thereby helping to improve the humidification efficiency of the steam humidification equipment 100. It can be understood that the number of air holes 251 can be determined according to actual production requirements and is not specifically limited here.

[0097] One end of the rotating shaft 33 close to the shielding cover 25 can be plugged into and matched with the shielding cover 25 to facilitate the positioning and installation of the rotating assembly 3 and the shielding cover 25, while also helping to improve the stability of the rotating assembly 3.

[0098] Combine Figure 3 and Figure 10 In some embodiments of the present invention, the steam humidification device 100 also includes an upper cover seal 6, which is arranged at one end of the shielding cover 25 close to the cover body 24. The upper cover seal 6 is used to seal the shielding cover 25 and the cover body 24 to prevent steam from leaking from between the shielding cover 25 and the cover body 24, which is beneficial to improving the humidification efficiency of the steam humidification device 100.

[0099] Combine Figure 10 as well as Figures 13 to 15 In some embodiments of the present invention, the upper cover plate 242 includes a main body 2423 and a cover 2424. The main body 2423 is provided with an upper cover cavity 2421 and an air outlet 2422. The upper cover cavity 2421 is formed as a groove structure that is recessed toward the side close to the sealing cover 241. The air outlet 2422 can be arranged in the upper cover cavity 2421 so that the air outlet 2422 connects the guide channel 23 and the upper cover cavity 2421.

[0100] Combine Figures 13 to 15 The top of the upper cover cavity 2421 is open, the cover body 2424 covers the open mouth of the upper cover cavity 2421 and the cover body 2424 is provided with a steam outlet 21, the steam outlet 21 can connect the upper cover cavity 2421 with the external space so that steam can be discharged from the steam humidification device 100 into the external space.

[0101] Among them, the cover body 2424 is sealed on the open mouth of the upper cover cavity 2421, which is beneficial to reducing the risk of dust and other debris falling into the upper cover cavity 2421, and since the open mouth of the upper cover cavity 2421 is located at the top of the upper cover cavity 2421, the cover body 2424 with the steam outlet 21 is arranged at the open mouth of the upper cover cavity 2421, which is also beneficial to allow the steam to flow fully in the upper cover cavity 2421, extend the flow path of the steam, improve the cooling effect of the steam, and help reduce the heating effect of the steam on the cover body 2424, preventing the user from getting scalded when touching the cover body 2424.

[0102] It should be noted that “the top of the upper cover cavity 2421 ” refers to a side of the upper cover cavity 2421 away from the steam generating chamber 11 in a direction parallel to the central axis of the rotating shaft 33 .

[0103] Combine Figures 8 to 10 In some embodiments of the present invention, the cover body 2424 is provided with a plurality of steam outlets 21 arranged at intervals, which is beneficial to improving the efficiency of the steam humidification device 100 in discharging steam, thereby improving the humidification efficiency of the steam humidification device 100, and the low-temperature air in the external space can flow into the upper cover cavity 2421 through the steam outlet 21 and exchange heat with the steam, which is beneficial to further improve the cooling effect of the steam and prevent the high-temperature steam from scalding the user.

[0104] Combine Figures 8 to 10In some embodiments of the present invention, the cover body 2424 is formed in a grid shape so that a plurality of steam outlets 21 arranged at intervals can be formed on the cover body 2424, which is conducive to improving the processing convenience of the cover body 2424, and is conducive to improving the aesthetics of the cover assembly 2 while ensuring the connectivity between the upper cover cavity 2421 and the external space.

[0105] Among them, the cover body 2424 can be detachably connected to the main body 2423. For example, the cover body 2424 can be detachably connected to the main body 2423 by means of snap connection or threaded connection. When the structure in the upper cover cavity 2421 needs to be inspected or when the cover body 2424 is damaged, the cover body 2424 can be removed from the main body 2423, effectively improving the maintenance convenience of the cover assembly 2.

[0106] Combine Figure 2 and Figure 3 as well as Figure 10 On the same projection plane, the orthographic projection plane of the air outlet portion 2422 and the orthographic projection of the outlet end 312 are staggered, and the projection plane and the rotation axis of the rotating component 3 are perpendicularly arranged.

[0107] In the direction parallel to the rotation axis of the rotating component 3, the orthographic projection surface of the air outlet portion 2422 and the orthographic projection surface of the outlet end 312 are staggered, which is conducive to further increasing the flow path of the steam to improve the cooling effect of the steam, prevent the user from being scalded by the high-temperature steam discharged by the steam humidification equipment 100, and is conducive to improving the safety of use of the steam humidification equipment 100.

[0108] Exemplarily, the orthographic projection of the outlet end 312 can be located in the middle of the orthographic projection of the upper cover plate 242, and the air outlet portion 2422 can be arranged on the side of the upper cover plate 242 away from the outlet end 312 in the first direction, so as to achieve the staggered setting of the orthographic projection of the air outlet portion 2422 and the orthographic projection of the outlet end 312, so as to extend the flow path of the steam and improve the cooling effect of the steam.

[0109] Combine Figure 2 、 Figure 3 and Figure 10 In some embodiments of the present invention, the air outlet portion 2422 protrudes from the upper cover plate 242 in a direction away from the sealing cover 241 .

[0110] Specifically, the air outlet portion 2422 can be arranged on the bottom wall of the upper cover cavity 2421, so that the air outlet portion 2422 connects the guide channel 23 and the upper cover cavity 2421, and the air outlet portion 2422 can protrude from the bottom wall of the upper cover cavity 2421 in the direction away from the guide channel 23. A channel structure is formed in the air outlet portion 2422. After the steam flows from the guide channel 23 into the channel structure of the air outlet portion 2422, it is discharged into the upper cover cavity 2421 through the air outlet 24221 of the air outlet portion 2422, which is conducive to further extending the flow path of the steam and improving the cooling effect of the steam.

[0111] The air outlet 24221 is located on the peripheral wall of the air outlet portion 2422. The steam can be ejected along the first direction after passing through the air outlet 24221, so that the steam can flow to the steam outlet 21 on the cover body 2424 after fully flowing in the upper cover cavity 2421, thereby preventing the steam from flowing out of the air outlet 24221 and being discharged directly through the steam outlet 21 due to the air outlet 24221 being directly opposite to the steam outlet 21, which is beneficial to further improve the cooling effect of the steam.

[0112] Optionally, the air outlet portion 2422 can be integrally formed with the upper cover plate 242, or the air outlet portion 2422 can be separately formed and installed in the upper cover cavity 2421. The specific setting method of the air outlet portion 2422 and the upper cover plate 242 can be determined according to actual production requirements and is not specifically limited here.

[0113] In other embodiments of the present invention, the air outlet 24221 can be formed on the side wall of the upper cover cavity 2421, so that the air outlet 24221 can connect the guide channel 23 and the upper cover cavity 2421 without the need to process the air outlet portion 2422, which is beneficial to simplify the structure of the cover assembly 2 and reduce the production and processing cost of the cover assembly 2.

[0114] Combine Figure 3 、 Figures 10 to 14 In some embodiments of the present invention, the sealing cover 241 is provided with a first annular protrusion 2411 protruding toward the upper cover plate 242, and the upper cover plate 242 is provided with a second protrusion 2425 protruding toward the sealing cover 241. The first protrusion 2411 and the second protrusion 2425 cooperate to define the guide channel 23.

[0115] A groove structure open to the upper cover plate 242 is defined between the first protrusion 2411 and the sealing cover 241, and a groove structure open to the sealing cover 241 is defined between the second protrusion 2425 and the upper cover plate 242. When the sealing cover 241 and the upper cover plate 242 are positioned and installed, the first protrusion 2411 and the second protrusion 2425 cooperate together. For example, the first protrusion 2411 can be snap-fitted with the second protrusion 2425 in a direction parallel to the central axis of the rotating shaft 33, so that the first protrusion 2411 and the second protrusion 2425 can jointly define the guide channel 23, or the first protrusion 2411 and the second protrusion 2425 can be plug-fitted, so that the first protrusion 2411 and the second protrusion 2425 can jointly define the guide channel 23.

[0116] Combine Figure 3 、 Figure 11 and Figure 14 A first hole 2413 is provided on the sealing cover 241, and the first hole 2413 is located in the groove structure, and the first hole 2413 can be opposite to the outlet end 312 to connect with the outlet end 312, and a second hole 2426 is provided on the upper cover plate 242, and the second hole 2426 is located in the groove structure, and the second hole 2426 is opposite to the air outlet portion 2422 to connect with the air outlet portion 2422.

[0117] Thus, the guide channel 23 can be connected to the outlet end 312 and the air outlet portion 2422 respectively through the first hole 2413 and the second hole 2426, so as to realize the function of the guide channel 23 connecting the steam channel 31 with the upper cover cavity 2421, and the guide channel 23 can limit the flow path of the steam, prevent the steam from diffusing between the sealing cover 241 and the upper cover plate 242, increase the flow rate of the steam, and reduce the condensation of the steam.

[0118] Combine Figure 2 、 Figure 3 and Figure 10 In some embodiments of the present invention, the second protrusion 2425 is inserted into the first protrusion 2411, that is, in the direction parallel to the central axis of the rotating shaft 33, the area of the orthographic projection surface of the groove structure is larger than the area of the orthographic projection surface of the groove structure. During the assembly process of the upper cover plate 242 and the sealing cover 241, the second protrusion 2425 can be inserted into the groove structure defined by the first protrusion 2411 and the sealing cover 241 to facilitate the positioning and installation of the second protrusion 2425 and the first protrusion 2411.

[0119] The second protrusion 2425 stops at the sealing cover 241, which is conducive to forming a closed guide channel 23 between the second protrusion 2425 and the first protrusion 2411, and a sealing component 4 is provided between the inner peripheral wall of the first protrusion 2411 and the outer peripheral wall of the second protrusion 2425. The sealing component 4 can seal the inner peripheral wall of the first protrusion 2411 and the outer peripheral wall of the second protrusion 2425, which is conducive to further improving the sealing effect of the guide channel 23 and preventing the steam flowing into the guide channel 23 from leaking.

[0120] like Figure 10 As shown, in some embodiments of the present invention, a pressure relief channel 7 is provided on the cover assembly 2, and the pressure relief channel 7 is respectively connected to the steam generating chamber 11 and the upper cover cavity 2421. When the pressure inside the steam humidifying device 100 is too high, the pressure relief channel 7 opens to release the internal pressure of the steam humidifying device 100, thereby improving the safety of use of the steam humidifying device 100.

[0121] Among them, a part of the pressure relief channel 7 is respectively formed on the sealing cover 241 and the upper cover plate 242, and the steam humidification equipment 100 also includes a sealing ring 5, which can seal a part of the pressure relief channel 7 formed on the sealing cover 241 and the upper cover plate 242, which is beneficial to improving the pressure relief effect, and is beneficial to preventing dust and other debris from entering the steam humidification equipment 100 through the pressure relief channel 7 during the pressure relief process, thereby ensuring the normal operation of the steam humidification equipment 100.
