[0044] Next, reference is made to Figures 1 - 10 Describe the steam humidification device 100 according to an embodiment of the present utility model.
[0045] Combined with Figures 1 to 3 , the steam humidification device 100 according to an embodiment of the present utility model includes: a steam generation main body 1 and a cover assembly 2. A steam generation chamber 11 is formed inside the steam generation main body 1, and the cover assembly 2 is provided on the steam generation main body 1 and seals the open end of the steam generation chamber 11.
[0046] Referring to Figure 3 , a steam generation chamber 11 with one end open is formed inside the steam generation main body 1. The steam generation chamber 11 is used to hold water, and the steam generation main body 1 can heat and evaporate the water to generate steam. The cover assembly 2 is arranged to seal the open end of the steam generation chamber 11 to prevent dust and other sundries from falling into the steam generation chamber 11, and when the steam humidification device 100 is not needed, the cover assembly 2 can prevent the waste of water caused by the evaporation of the water in the steam generation chamber 11.
[0047] Combined with Figures 1 to 3 , the cover assembly 2 includes an upper cover cavity 2421. The upper cover cavity 2421 is provided with an air outlet 24221 and a plurality of steam channels 20. The upper cover cavity 2421 is communicated with the steam generation chamber 11 through the air outlet 24221, and the steam in the steam generation chamber 11 can flow from the steam generation chamber 11 into the upper cover cavity 2421 through the air outlet 24221.
[0048] Further combined withFigures 7 to 9 , the steam passage 20 is provided with air outlet holes 24244 and a steam outlet 21. The steam outlet 21 is used to discharge steam to the external space. The steam passage 20 communicates with the upper cover cavity 2421 through the air outlet holes 24224.
[0049] It should be noted that the "external space" refers to the space outside the steam humidifying device 100, which can be an indoor space or an outdoor space.
[0050] The steam flowing into the upper cover cavity 2421 can flow into the steam passage 20 through the air outlet holes 24244, and can further flow from the steam passage 20 into the external space through the steam outlet 21, so as to realize the humidifying function of the steam humidifying device 100 for the external space.
[0051] As Figure 9 shown, the opening of the air outlet hole 24244 faces the remaining inner peripheral wall of the steam passage 20, that is, the opening of the air outlet hole 24244 faces the inner peripheral wall of the steam passage 20 where the steam outlet 21 is not formed.
[0052] For example, the steam outlet 21 can be formed on a side wall surface of the steam passage 20 opposite to and away from the steam generating cavity 11. The air outlet holes 24244 can be formed on the peripheral wall of the steam passage 20 arranged at an angle with the steam generating cavity 11. The opening direction of the air outlet holes 24244 can be perpendicular to the opening direction of the steam outlet 21, so that the flow direction of the steam can be changed during the process of the steam flowing from the air outlet holes 24244 to the steam outlet 21, which is beneficial to extending the flow path of the steam, improving the steam cooling effect, preventing the user from being scalded due to the high temperature of the steam discharged by the steam humidifying device 100, and is beneficial to improving the use safety of the steam humidifying device 100.
[0053] According to the steam humidifying device 100 of the present utility model, by providing the steam passage 20 provided with the air outlet holes 24244 and the steam outlet 21, and making the opening of the air outlet holes 24244 face the remaining inner peripheral wall of the steam passage 20, so that the flow direction of the steam can be changed during the process of the steam flowing from the air outlet holes 24244 to the steam outlet 21, which is beneficial to extending the flow path of the steam, improving the steam cooling effect, preventing the user from being scalded due to the high temperature of the steam discharged by the steam humidifying device 100, and is beneficial to improving the use safety of the steam humidifying device 100.
[0054] Referring to Figure 9 , in some embodiments of the present utility model, the air outlet holes 24244 and the steam outlet 21 are located on adjacent side walls of the steam passage 20.
[0055] Exemplarily, the steam outlet 21 can be arranged on the top wall of the steam channel 20 (i.e., the side wall of the steam channel 20 away from the steam generation chamber 11), and the air outlet 24244 can be arranged on the side wall of the steam channel 20 adjacent to the top wall, so as to facilitate the layout of the steam channel 20. At the same time, it can prevent the steam from flowing rapidly through the steam channel 20 due to the openings of the air outlet 24244 and the steam outlet 21 facing each other, which is beneficial to extending the flow path of the steam and improving the steam cooling effect.
[0056] Combined with Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 9 In some embodiments of the present invention, the top of the upper cover cavity 2421 is open, and the cover assembly 2 further includes a cover body 2424 covering the open top of the upper cover cavity 2421, and the cover body 2424 is provided with a steam channel 20.
[0057] The cover body 2424 covers the open top of the upper cover cavity 2421, which is beneficial to reducing the risk of dust and other foreign matters flowing into the upper cover cavity 2421. And since the open top of the upper cover cavity 2421 is located at the top of the upper cover cavity 2421, arranging the cover body 2424 provided with the steam channel 20 at the open top of the upper cover cavity 2421 is also beneficial to enabling the steam to fully flow in the upper cover cavity 2421, extending the flow path of the steam, improving the steam cooling effect, and being beneficial to reducing the heating effect of the steam on the cover body 2424 and preventing scalding when the user touches the cover body 2424.
[0058] It should be noted that the "top of the upper cover cavity 2421" refers to the side of the upper cover cavity 2421 away from the steam generation chamber 11.
[0059] Combined with Figures 7 to 10 The cover body 2424 includes: a main body portion 24241 and a plurality of partition ribs 24242. A hollowed-out area a is formed in the main body portion 24241 and runs through in the height direction. The plurality of partition ribs 24242 are arranged in the hollowed-out area a and are respectively connected to the main body portion 24241 to divide the hollowed-out area a into a plurality of steam outlets 21.
[0060] It should be noted that the "height" direction is the same as the "vertical" direction, both referring to the direction extending from the upper cover cavity 2421 to the steam generation chamber 11 or from the steam generation chamber 11 to the upper cover cavity 2421.
[0061] By providing a hollowed-out area a and a plurality of partition ribs 24242 on the main body portion 24241, a plurality of steam outlets 21 can be formed on the cover body 2424 without separately processing the steam outlets 21 on the cover body 2424, which is beneficial to improving the processing convenience of the cover body 2424. Moreover, the size of the steam outlets 21 can be adjusted by adjusting the spacing between the plurality of partition ribs 24242 to meet the size requirements of the steam outlets 21, enabling the cover body 2424 to be adapted to different steam humidifying devices 100.
[0062] Among them, in combination with Figures 7 to 10 , the plurality of partition ribs 24242 are sequentially and spacedly arranged within the hollowed-out area a to divide the hollowed-out area a into a plurality of strip-shaped steam outlets 21, increasing the size of the steam outlets 21. Thereby, it is beneficial to improving the efficiency of discharging steam from the steam humidifying device 100, and facilitating the inflow of low-temperature air in the external space into the upper cover cavity 2421 and exchanging heat with the steam, which is beneficial to improving the cooling effect of the steam and reducing the number of partition ribs 24242, thus reducing the production and processing cost of the cover body 2424.
[0063] The plurality of partition ribs 24242 are cross-arranged within the hollowed-out area a, which is beneficial to improving the structural strength of the cover body 2424, reducing the risk of the cover body 2424 being crushed and damaged, and reducing the risk of dust and other sundries falling into the upper cover cavity 2421.
[0064] Optionally, the cover body 2424 can simultaneously satisfy that the plurality of partition ribs 24242 are sequentially and spacedly arranged within the hollowed-out area a and the plurality of partition ribs 24242 are cross-arranged within the hollowed-out area a. The specific structural setting of the cover body 2424 can be determined according to actual production requirements and will not be specifically limited herein.
[0065] In combination with Figures 8 to 10 , the cover body 2424 further includes a shielding rib 24243. One of the adjacent partition ribs 24242 is connected to the shielding rib 24243. The shielding rib 24243 is disposed opposite to the steam outlet 21, and the shielding rib 24243 is spaced from the other of the adjacent partition ribs 24242 to define an air outlet 24244 communicating with the steam outlet 21.
[0066] In the vertical direction, the shielding rib 24243 is located on the side of the steam outlet 21 close to the upper cover cavity 2421, that is, the shielding rib 24243 is disposed below the steam outlet 21 to shield the steam outlet 21 between two adjacent partition ribs 24242, and the shielding rib 24243 is spaced from the other of the adjacent partition ribs 24242 in the vertical direction, so that an air outlet 24244 is defined between the shielding rib 24243 and the other of the adjacent partition ribs 24242.
[0067] During the process of the steam flowing towards the steam outlet 21, since the blocking rib 24243 blocks the steam outlet 21 at the lower part of the steam outlet 21, the steam cannot be directly discharged from the steam outlet 21 in the vertical direction. After flowing through the blocking rib 24243, the steam flows towards the air outlet hole 24244 and further flows towards the steam outlet 21 through the air outlet hole 24244, thereby realizing the discharge of the steam.
[0068] Thus, by providing the blocking rib 24243, the flow path of the steam can be further extended, and the steam can fully exchange heat with the low-temperature air in the upper cover cavity 2421 before flowing through the surface of the cover body 2424 facing away from the upper cover cavity 2421, so as to further reduce the temperature of the steam, effectively preventing the user from being scalded due to the too high temperature of the steam discharged by the steam humidifying device 100, which is beneficial to further improving the use safety of the steam humidifying device 100.
[0069] Combined Figures 8 to 10 with Figures 8 to 10 , in some embodiments of the present utility model, in the arrangement direction of the plurality of partition ribs 24242, a first extension rib 24245 and a second extension rib 24246 are respectively provided on both sides of each partition rib 24242. The blocking rib 24243 is connected to the first extension rib 24245, and the blocking rib 24243 and the adjacent second extension rib 24246 are spaced apart to define the air outlet hole 24244.
[0070] The first extension rib 24245 and the second extension rib 24246 respectively extend from the partition rib 24242 towards the direction close to the upper cover cavity 2421 in the vertical direction. The blocking rib 24243 is connected to the end of the first extension rib 24245 far from the partition rib 24242, and the blocking rib 24243 extends from the first extension rib 24245 towards the second extension rib 24246 on the adjacent partition rib 24242. The blocking rib 24243, the first extension rib 24245 and the second extension rib 24246 jointly define the steam channel 20, and the blocking rib 24243 and the adjacent second extension rib 24246 are spaced apart in the vertical direction to define the air outlet hole 24244, so as to make the steam outlet 21 and the air outlet hole 24244 respectively located on the adjacent side walls of the steam channel 20, thereby realizing the extension of the steam flow path and improving the steam cooling effect.
[0071] As Figure 10 shown, the dimension L of the air outlet hole 24244 in the height direction satisfies the relationship: L > 3 mm, which is beneficial to ensuring the efficiency of the steam flowing through the air outlet hole 24244 towards the steam outlet 21, and at the same time facilitating the low-temperature air in the external space to flow into the upper cover cavity 2421 through the air outlet hole 24244, which is beneficial to ensuring the steam cooling effect.
[0072] Preferably, L satisfies the relationship: 3 mm < L < 50 mm. When L < 3 mm, the heat exchange effect between the steam and the low-temperature air is poor, the steam outflow efficiency is low, and at the same time, it is easy to cause a large noise when the steam flows through the air outlet 24244. When L > 50 mm, the first extended rib 24245, the second extended rib 24246, and the shielding rib 24243 will occupy the space in the upper cover cavity 2421, making it inconvenient to install other structures in the upper cover cavity 2421 and affecting the assembly of the cover assembly 2.
[0073] The dimension H of the second extended rib 24246 in the height direction satisfies the relationship: H > 1.5 mm, that is, the distance between the air outlet 24244 of the steam passage and the steam outlet 21 is greater than 1.5 mm, which is beneficial to extending the flow path of the steam, and thus is beneficial to further reducing the temperature of the steam.
[0074] Preferably, H satisfies the relationship: 1.5 mm < H < 50 mm. When H < 1.5 mm, the distance between the air outlet 24244 and the steam outlet 21 is too close, the effect of extending the steam flow path is poor, and there is a risk that dust will fall into the upper cover cavity 2421 through the steam outlet 21 and the air outlet 24244. When H > 20 mm, the first extended rib 24245, the second extended rib 24246, and the shielding rib 24243 will occupy the space in the upper cover cavity 2421, making it inconvenient to install other structures in the upper cover cavity 2421 and affecting the assembly of the cover assembly 2.
[0075] Optionally, the cover body 2424 can simultaneously satisfy that the dimension L of the air outlet 24244 in the height direction is > 3 mm and the dimension H of the second extended rib 24246 in the height direction is > 1.5 mm, so as to extend the steam flow path while ensuring the steam flow effect.
[0076] Refer to Figure 1 , in some embodiments of the present utility model, each steam outlet 21 is formed in a long strip shape.
[0077] Since each steam outlet 21 is formed in a long strip shape, the area of each steam outlet 21 is increased, the efficiency of the steam discharged from the upper cover cavity 2421 is improved, and at the same time, it is beneficial to improve the efficiency of the low-temperature air in the external space flowing into the upper cover cavity 2421, thereby being beneficial to improving the steam cooling effect, preventing the steam humidifying device 100 from discharging high-temperature steam and scalding the user, and improving the use safety of the steam humidifying device 100.
[0078] Combined with Figures 1 to 3 , in some embodiments of the present utility model, the air outlet 24221 and the steam outlet 21 are located on the opposite side walls of the upper cover cavity 2421.
[0079] Exemplarily, the air outlet 24221 can be located on the bottom wall of the upper cover cavity 2421, and the steam outlet 21 can be located on the top wall of the upper cover cavity 2421, so that the steam outlet 21 and the air outlet 24221 are arranged at intervals. After the steam is discharged from the air outlet 24221, the steam can flow through the upper cover cavity 2421 and flow towards the steam outlet 21, realizing the extension of the steam flow path, which is beneficial to improving the cooling effect of the steam.
[0080] Combined with Figures 1 to 3 , the upper cover cavity 2421 includes a protruding portion 2422 protruding away from the steam generation cavity 11, and the air outlet 24221 is provided on the protruding portion 2422.
[0081] The upper cover cavity 2421 is located above the steam generation cavity 11. By arranging the protruding portion 2422 provided with the air outlet 24221 on the bottom wall of the upper cover cavity 2421, it is convenient for the air outlet 24221 to communicate the steam generation cavity 11 and the upper cover cavity 2421. Since the protruding portion 2422 protrudes from the bottom wall of the upper cover cavity 2421 in a direction away from the steam generation cavity 11 and the protruding portion 2422 is formed as a hollow structure, after the steam flows from the steam generation cavity 11 into the protruding portion 2422, it is discharged into the upper cover cavity 2421 through the air outlet 24221, which is beneficial to further extending the steam flow path and improving the cooling effect of the steam.
[0082] Optionally, the protruding portion 2422 can be formed as a cylindrical protrusion or a cuboid protrusion, etc., and the protruding portion 2422 can be integrally formed with the bottom wall of the upper cover cavity 2421, or the protruding portion 2422 can be detachably arranged with the bottom wall of the upper cover cavity 2421. The specific arrangement form of the protruding portion 2422 can be determined according to actual production requirements and will not be specifically limited here.
[0083] Combined with Figure 3 and Figure 4 , in some embodiments of the present invention, the protruding portion 2422 is located at one end of the upper cover cavity 2421, and the air outlet 24221 is provided on the outer peripheral wall of the protruding portion 2422.
[0084] The protruding portion 2422 is located at one end of the upper cover cavity 2421 in the first direction, and the opening direction of the air outlet 24221 faces the first direction. When the steam passes through the air outlet 24221, due to the small opening area of the air outlet 24221, the steam can be accelerated when passing through the air outlet 24221, and the bottom end of the air outlet 24221 is arranged close to the bottom wall of the upper cover cavity 2421. Since the steam has an initial velocity when discharged from the air outlet 24221, the steam can flow along the bottom wall of the upper cover cavity 2421 from one end of the upper cover cavity 2421 where the protruding portion 2422 is located to the other end of the upper cover cavity 2421, so as to realize the extension of the steam flow path and improve the cooling effect of the steam.
[0085] In the related art, the air outlet is usually set relatively high. In order to enable the steam to flow along the bottom wall of the upper cover after flowing out of the air outlet, it is usually necessary to bend the structure with the air outlet towards the bottom wall side of the upper cover, resulting in poor processing convenience of the cover assembly.
[0086] In this application, by arranging the air outlet 24221 on the outer peripheral wall of the air outlet part 2422 and setting the bottom end of the air outlet 24221 close to the bottom wall of the upper cover cavity 2421, it is possible to make the steam flow along the bottom wall of the upper cover cavity 2421 without bending the air outlet part 2422, which is beneficial to improving the processing convenience of the cover assembly 2.
[0087] It should be noted that the "first direction" can be understood as the width direction of the upper cover cavity 2421 or the steam humidifying device 100. For a specific direction indication, reference can be made to Figure 3 or Figure 4 .
[0088] In some other embodiments of the present utility model, the air outlet 24221 can be directly formed on the side wall of the upper cover cavity 2421, so that the air outlet 24221 can communicate the steam generating cavity 11 with the upper cover cavity 2421 without machining the air outlet part 2422, which is beneficial to simplifying the structure of the cover assembly 2 and reducing the production and processing cost of the cover assembly 2.
[0089] Combined with Figure 2 and Figure 3 , in some embodiments of the present utility model, the air outlet 24221 is formed as a vertically placed rectangle.
[0090] It should be noted that the "vertical direction" refers to the direction extending from the steam generating cavity 11 to the cover assembly 2, and the "horizontal direction" is perpendicular to the vertical direction and the first direction respectively.
[0091] The cross-sectional shape of the air outlet 24221 is a rectangle. The length direction of the air outlet 24221 is parallel to the direction extending from the steam generating cavity 11 to the upper cover cavity 2421, that is, the longer side of the cross-section of the air outlet 24221 extends in the vertical direction, and the shorter side of the cross-section of the air outlet 24221 extends in the horizontal direction, so as to make the bottom end of the air outlet 24221 close to the bottom wall of the upper cover cavity 2421, thereby facilitating the steam to flow along the bottom wall of the upper cover cavity 2421 after flowing out of the air outlet 24221, which is beneficial to improving the steam cooling effect.
[0092] Among them, the length of the shorter side of the air outlet 24221 is greater than 3 mm, so as to facilitate the processing of the air outlet 24221 and prevent the steam flow effect from being affected due to the small width of the air outlet 24221.
[0093] In addition, the cross-sectional area of the air outlet 24221 is greater than 20 mm2 , to ensure that the air outlet 24221 can meet the national security standard specifications and guarantee the safety of the steam humidifying device 100.
[0094] In some other embodiments of the present utility model, the air outlet 24221 can also be formed into a circular shape or other shapes. Among them, when the air outlet 24221 is formed into a circular shape, the diameter of the air outlet 24221 is greater than 5 mm, which is beneficial to improving the efficiency of steam discharging from the air outlet 24221 and is also beneficial to improving the processing convenience of the air outlet 24221.
[0095] Such as Figure 1 As shown, in some embodiments of the present utility model, there are multiple steam outlets 21 which are arranged at intervals, which is beneficial to improving the efficiency of the steam humidifying device 100 in discharging steam, thus beneficial to improving the humidifying efficiency of the steam humidifying device 100. And the low-temperature air in the external space can flow into the upper cover cavity 2421 through the multiple steam outlets 21 and exchange heat with the steam, which is beneficial to further improving the cooling effect of the steam and preventing the high-temperature steam from scalding the user.
[0096] Combined with Figures 1 to 4 , in some embodiments of the present utility model, the cover assembly 2 includes a cover main body 24 and a shielding cover 25. The shielding cover 25 is arranged on the side of the cover main body 24 close to the steam generating cavity 11, and the shielding cover 25 and the cover main body 24 jointly define a first space 22. The first space 22 is communicated with the steam generating cavity 11, and the steam flows into the first space 22 after flowing out of the steam generating cavity 11.
[0097] The cover main body 24 includes an upper cover plate 242 and a sealing cover 241. An upper cover cavity 2421 is formed on the upper cover plate 242. The sealing cover 241 is arranged on the side of the upper cover plate 242 close to the steam generating cavity 11 and jointly defines a second space 23 with the upper cover plate 242. The second space 23 is communicated with the upper cover cavity 2421.
[0098] Among them, the shielding cover 25 is arranged on the side of the sealing cover 241 close to the steam generating cavity 11 and jointly defines the first space 22 with the sealing cover 241. The first space 22 is respectively communicated with the second space 23 and the steam generating cavity 11.
[0099] The steam flows out of the steam generating cavity 11 and flows through the first space 22 and the second space 23 in sequence, and can further flow into the upper cover cavity 2421 from the second space 23. Then, after flowing through the upper cover cavity 2421, the steam can be discharged from the steam humidifying device 100 through the steam outlet 21.
[0100] Thus, through the structural design of the cover assembly 2, a first space 22, a second space 23, and an upper cover cavity 2421 are respectively formed in the cover assembly 2 to extend the flow path of the steam flowing through the cover assembly 2, which is beneficial to further improving the steam cooling effect.
[0101] Combined with Figures 3 to 6 , the upper cover plate 242 includes a body portion 2423 and a cover body 2424. An upper cover cavity 2421 and an air outlet portion 2422 are provided in the body portion 2423. The upper cover cavity 2421 forms a groove structure recessed toward the steam generation cavity 11 side. The air outlet portion 2422 is provided in the upper cover cavity 2421 to facilitate the air outlet portion 2422 to communicate the second space 23 and the upper cover cavity 2421.
[0102] Combined with Figures 1 to 3 , the steam humidifying device 100 according to an embodiment of the present invention includes: a steam generation main body 1 and a cover assembly 2. A steam generation cavity 11 is formed in the steam generation main body 1. The cover assembly 2 is provided on the steam generation main body 1 and seals the open end of the steam generation cavity 11.
[0103] Referring to Figure 3 , an open-ended steam generation cavity 11 is formed in the steam generation main body 1. The steam generation cavity 11 is used for holding water, and the steam generation main body 1 can heat and evaporate the water to generate steam. The cover assembly 2 can seal the open end of the steam generation cavity 11 to prevent dust and other sundries from falling into the steam generation cavity 11, and when the steam humidifying device 100 is not needed, the cover assembly 2 can prevent waste of water due to the evaporation of the water in the steam generation cavity 11.
[0104] Combined with Figures 1 to 3 , the cover assembly 2 includes an upper cover cavity 2421 with an open top. The upper cover cavity 2421 is provided with an air outlet 24221. The air outlet 24221 is disposed adjacent to the bottom wall of the upper cover cavity 2421 and communicates with the steam generation cavity 11. The steam generated in the steam generation cavity 11 can flow into the upper cover cavity 2421 through the air outlet 24221. And since the air outlet 24221 is disposed adjacent to the bottom wall of the upper cover cavity 2421, the steam can flow along the bottom wall of the upper cover cavity 2421 after flowing out of the air outlet 24221, which is beneficial to extending the flow path of the steam and improving the steam cooling effect.
[0105] Combined with Figures 1 to 3 , the cover assembly 2 further includes a cover body 2424 covering the open top of the upper cover cavity 2421. The cover body 2424 is provided with a steam outlet 21. The steam outlet 21 is used to discharge the steam to the external space.
[0106] The steam outlet 21 is connected to the upper cover cavity 2421 , and the steam flowing into the upper cover cavity 2421 can be discharged from the upper cover cavity 2421 into the external space through the steam outlet, so as to realize the humidification function of the steam humidification device 100 on the external space.
[0107] Combine Figures 1 to 3 The steam outlet 21 and the air outlet 2421 are spaced apart from each other. For example, the air outlet 24221 and the steam outlet 21 are located on different side walls of the upper cover cavity 2421 .
[0108] It should be noted that the “side walls of the upper cover cavity 2421 ” include the top wall, bottom wall and peripheral wall of the upper cover cavity 2421 .
[0109] Exemplarily, the air outlet 24221 and the steam outlet 21 can be respectively arranged on two opposite side walls in the upper cover cavity 2421, or the air outlet 24221 and the steam outlet 21 can be respectively arranged on two mutually perpendicular side walls in the upper cover cavity 2421. By arranging the air outlet 24221 and the steam outlet 21 on different side walls of the upper cover cavity 2421, it is beneficial to allow the steam to flow fully in the upper cover cavity 2421, that is, it is beneficial to further extend the flow path of the steam, improve the cooling effect of the steam, prevent the user from being scalded due to the high temperature of the steam discharged from the steam humidification device 100, and help improve the safety of use of the steam humidification device 100.
[0110] According to the steam humidifying device 100 of the present invention, the air outlet 24221 is arranged adjacent to the bottom wall of the upper cover cavity 2421, so that the steam can flow along the bottom wall of the upper cover cavity 2421 after flowing out of the air outlet 24221, which is beneficial to extending the flow path of the steam and improving the steam cooling effect. The air outlet 24221 is arranged at intervals from the steam outlet 21 so that the steam can fully flow in the upper cover cavity 2421, which is beneficial to further extending the flow path of the steam, thereby further improving the steam cooling effect, preventing the steam humidifying device 100 from discharging high-temperature steam and scalding the user, and improving the safety of use of the steam humidifying device 100.
[0111] In addition, the steam humidification device 100 of the present application can reduce the temperature of the steam without setting up other structures, which is beneficial to simplifying the structure of the steam humidification device 100 and thus beneficial to reducing the production cost of the steam humidification device 100.
[0112] Combine Figures 1 to 3 In some embodiments of the present invention, the upper cover cavity 2421 includes an air outlet portion 2422 protruding toward a side away from the steam generating chamber 11 , and an air outlet 24221 is provided on an outer peripheral wall of the air outlet portion 2422 .
[0113] The upper cover cavity 2421 is located above the steam generating cavity 11. By arranging the air outlet part 2422 on the bottom wall of the upper cover cavity 2421, it is convenient for the air outlet 24221 to communicate the steam generating cavity 11 with the upper cover cavity 2421. Since the air outlet part 2422 protrudes from the bottom wall of the upper cover cavity 2421 in a direction away from the steam generating cavity 11 and the air outlet part 2422 is formed as a hollow structure, after the steam flows from the steam generating cavity 11 into the air outlet part 2422, it is exhausted into the upper cover cavity 2421 through the air outlet 24221, which is beneficial to further extend the flow path of the steam and improve the steam cooling effect.
[0114] Optionally, the air outlet part 2422 can be integrally formed with the bottom wall of the upper cover cavity 2421, or the air outlet part 2422 can be separately formed and installed on the bottom wall of the upper cover cavity 2421 through installation methods such as plug-in fit. The specific setting method of the air outlet part 2422 can be determined according to actual production requirements and will not be specifically limited here.
[0115] As Figure 1 shown, in some embodiments of the present invention, the opening direction of the air outlet 24221 is perpendicular to the opening direction of the steam outlet 21, so that the flow direction of the steam changes when the steam flows from the air outlet 24221 into the steam outlet 21, which is beneficial to extend the flow path of the steam and improve the steam cooling effect.
