[0049] Combined Figures 1 to 3 According to the steam humidification device 100 of the embodiment of the utility model, it comprises: a steam generation main body 110, a cover assembly 120 and an air outlet pipe 130, a steam generation cavity 111 is formed in the steam generation main body 110, the cover assembly 120 is arranged on the steam generation main body 110 and covers the open end of the steam generation cavity 111, the cover assembly 120 forms a steam cooling chamber 121 in communication with the external space, the air outlet pipe 130 is located in the steam cooling chamber 121 and is in communication with the steam generation, and the air outlet pipe 130 is provided with an air outlet 131, and the air outlet 131 is used for connecting the air outlet pipe 130 and the steam cooling chamber 121.

[0050] Exemplarily, the steam generation cavity 111 with one end open is formed in the steam generation main body 110, the steam generation cavity 111 is used for containing water, and the steam generation main body 110 can heat and evaporate the water in the steam generation cavity 111 to generate steam, the cover assembly 120 can cover the open end of the steam generation cavity 111 to prevent dust and other sundries from falling into the steam generation cavity 111, which is beneficial to ensure the cleanliness of the water in the steam generation cavity 111.

[0051] Further, the steam generated after the water in the steam generating cavity 111 evaporates can flow into the air outlet pipe 130 from the steam generating cavity 111, and further be discharged into the steam cooling chamber 121 through the air outlet 131, the steam cooling chamber 121 being in communication with an external space, and low-temperature air in the external space can enter the steam cooling chamber 121, so that the steam can exchange heat with the low-temperature air entering the steam cooling chamber 121 when flowing in the steam cooling chamber 121, to reduce the temperature of the steam, and then the steam can be discharged from the steam cooling chamber 121 into the external space, to realize humidification of the external space.

[0052] It should be noted that the "external space" refers to a space outside the steam humidifying device 100, which can be an indoor space or an outdoor space.

[0053] In some embodiments of the present application, the steam humidifying device 100 further comprises a steam cooling chamber 121, the steam cooling chamber 121 being in communication with the air outlet pipe 130 and the external space. Figures 4 to 7 In the axial direction of the air outlet pipe 130, the air outlet 131 is spaced apart from the top end of the air outlet pipe 130 to define a bubble breaking space 135 in the air outlet pipe 130.

[0054] For example, in the axial direction of the air outlet pipe 130, the bubble breaking space 135 is formed at a position above the air outlet 131 in the air outlet pipe 130, and in the process of the steam flowing from the air outlet pipe 130 to the air outlet 131, the steam can drive the bubbles formed thereby to move into the bubble breaking space 135, and the bubbles can break in the bubble breaking space 135, which is conducive to reducing the noise generated by the operation of the steam humidifying device 100, thereby improving the user's experience.

[0055] In the related art, the bubbles formed by the steam usually break outside the air outlet pipe, resulting in significant noise when the bubbles break, thereby causing the steam humidifying device to generate a large amount of noise when operating, affecting the user's experience.

[0056] In the present application, the air outlet 131 is spaced apart from the top end of the air outlet pipe 130 to define a bubble breaking space 135 in the air outlet pipe 130, and the bubbles formed by the steam can move into the bubble breaking space 135 under the driving of the steam and break in the bubble breaking space 135, the air outlet pipe 130 can block the propagation of the noise generated when the bubbles break, to weaken the noise propagated to the external space when the bubbles break, thereby reducing the noise generated by the operation of the steam humidifying device 100, and improving the user's experience.

[0057] In some embodiments of the present application, the steam humidifying device 100 further comprises a steam cooling chamber 121, the steam cooling chamber 121 being in communication with the air outlet pipe 130 and the external space. Figures 4 to 7 In some embodiments of the present application, in the axial direction of the air outlet pipe 130, the first end 132 of the air outlet pipe 130 is in communication with the steam generating cavity 111, and the second end 133 of the air outlet pipe 130 is blocked to form a blocking wall 134.

[0058] It should be noted that the axial direction of the air outlet pipe 130 is the height direction of the air outlet pipe 130.

[0059] Exemplarily, in the axial direction of the air outlet pipe 130, one end of the air outlet pipe 130 close to the steam generation cavity 111 is defined as the first end 132 of the air outlet pipe 130, and one end of the air outlet pipe 130 close to the open end of the steam generation cavity 111 is defined as the second end 133 of the air outlet pipe 130. The first end 132 of the air outlet pipe 130 is in communication with the steam generation cavity 111, and the steam formed in the steam generation cavity 111 can enter the air outlet pipe 130 through the first end 132 of the air outlet pipe 130. By blocking the second end 133 of the air outlet pipe 130, the steam can be prevented from directly flowing from the second end 133 of the air outlet pipe 130 to the open end of the steam cooling chamber 121, so that the steam can be discharged into the steam cooling chamber 121 through the air outlet 131 arranged in the circumferential direction of the air outlet pipe 130 for heat dissipation, and the heat dissipation effect of the steam is ensured.

[0060] Further, in the axial direction of the air outlet pipe 130, each air outlet 131 is arranged to be spaced from the blocking wall 134 to define a bubble breaking space 135. In the process of the steam flowing to the air outlet 131, the bubbles can be driven to move to the bubble breaking space 135, and the bubbles can be broken in the bubble breaking space 135. The air outlet pipe 130 can block the propagation of the noise generated when the bubbles break, so as to weaken the noise propagated to the outside space when the bubbles break, thereby facilitating the reduction of the noise generated when the steam humidifying device 100 operates.

[0061] After the noise test on the steam humidifying device 100 of the embodiment of the utility model and the steam humidifying device of the related art, it is found that the noise generated by the steam humidifying device 100 of the embodiment of the utility model is 2 decibels lower than the noise generated by the steam humidifying device of the related art.

[0062] In combination with Figures 2 to 4 , and Figures 8 to 10 In some embodiments of the utility model, a plurality of air outlets 131 are arranged on the air outlet pipe 130 in the circumferential direction, and the steam entering the air outlet pipe 130 can be divided into a plurality of air outlets 131 and then flow into the steam cooling chamber 121, which is beneficial to increase the heat exchange area of the steam, thereby facilitating the improvement of the heat dissipation effect of the steam, and further facilitating the reduction of the temperature of the steam discharged from the steam humidifying device 100, reducing the risk of the user being scalded by the steam, and improving the use safety of the steam humidifying device 100.

[0063] Further in combination with Figures 4 to 6 , the bubble breaking part 136 is arranged between any two circumferentially adjacent air outlets 131.

[0064] Exemplarily, the bubble breaking part 136 is arranged towards the inside of the air outlet pipe 130, and in the process of the bubbles moving towards the air outlet 131, the bubbles can be broken under the action of the bubble breaking part 136, that is, by arranging the bubble breaking part 136, the breaking of the bubbles in the air outlet pipe 130 can be further ensured, which is beneficial to reduce the risk of loud noise caused by the breaking of the bubbles outside the air outlet pipe 130, reduce the noise generated by the operation of the steam humidifying device 100, and improve the user experience.

[0065] In combination Figures 4 to 7 In some embodiments of the present application, the air outlet pipe 130 is provided with a guide wall 137 for defining the air outlet 131, and the parts of any two circumferentially adjacent guide walls 137 facing each other are arranged at an angle to define the bubble breaking part 136.

[0066] Exemplarily, the circumferential wall of the air outlet pipe 130 is formed with a through hole penetrating in the radial direction thereof, the through hole is in communication with the channel in the air outlet pipe 130, the radial outer side of the circumferential wall of the air outlet pipe 130 is provided with a guide wall 137, the guide wall 137 is arranged protruding from the circumferential wall of the air outlet pipe 130 in the radial direction and surrounds the through hole, and in the radial direction of the air outlet pipe 130, the end of the guide wall 137 away from the center axis of the air outlet pipe 130 defines the air outlet 131 in communication with the channel in the air outlet pipe 130. The steam entering the channel in the air outlet pipe 130 can flow to the guide wall 137 through the through hole, the guide wall 137 can guide the steam, which is beneficial to realize the orderly flow of the steam, and the steam can further flow to the air outlet 131 along the guide wall 137 and be discharged through the air outlet 131.

[0067] In the circumferential direction of the air outlet pipe 130, the parts of the two adjacent guide walls 137 facing each other are arranged at an angle, and the bubble breaking part 136 extending towards the inside of the air outlet pipe 130 is defined. When the bubbles move towards the air outlet 131 under the driving of the steam, the bubbles contact the bubble breaking part 136, the bubble breaking part 136 can break the bubbles, so that the bubbles break in the air outlet pipe 130, the air outlet pipe 130 blocks the propagation of the noise generated by the breaking of the bubbles, so as to weaken the noise propagated to the outside space when the bubbles break, thereby reducing the noise generated by the operation of the steam humidifying device 100.

[0068] In combination Figures 4 to 6 In some embodiments of the present application, in the same cross section of the air outlet pipe 130, the side walls of the cross sections of any two circumferentially adjacent guide walls 137 facing each other are defined as the first wall 138, the ends of the adjacent first walls 138 intersecting the air outlet pipe 130, and the included angle of the adjacent first walls 138 is an acute angle.

[0069] Exemplarily, in the circumferential direction of the air outlet pipe 130, the first wall 138 of two adjacent guide walls 137 is arranged adjacent to each other, and in the radial direction of the air outlet pipe 130, the first wall 138 is connected to the air outlet pipe 130 at one end of the air outlet pipe 130, which can also be understood as that the radially inner end of the first wall 138 is connected to the air outlet pipe 130, and the radially inner ends of the two adjacent first walls 138 intersect to make the part of the adjacent guide walls 137 towards each other arranged at an angle, thereby defining the bubble breaking part 136.

[0070] Further, the angle between the adjacent first walls 138 is an acute angle, that is, the bubble breaking part 136 is arranged at an acute angle at one end of the air outlet pipe 130 close to the central axis of the air outlet pipe 130 in the radial direction of the air outlet pipe 130, which is beneficial to improve the sharpness of the end of the bubble breaking part 136 close to the central axis of the air outlet pipe 130, thereby facilitating to improve the bubble breaking effect of the bubble breaking part 136 and reduce the risk of bubbles being discharged from the air outlet pipe 130.

[0071] Referring to Figure 9 In some embodiments of the present application, the part in the inner circumferential wall 1211 of the steam cooling chamber 121 farthest from the straight line of the air outlet pipe 130 is defined as the first part 1212, and at least one of the plurality of air outlets 131 is arranged opposite to the first part 1212 to send steam towards the first part 1212.

[0072] For example, the projection plane of the steam cooling chamber 121 in the axial direction of the air outlet pipe 130 can be substantially rectangular, and the air outlet pipe 130 can be arranged at one corner of the steam cooling chamber 121, then the part in the steam cooling chamber 121 farthest from the air outlet pipe 130 is defined as the first part 1212, and one of the plurality of air outlets 131 can be arranged opposite to the first part 1212, so that the steam discharged from the air outlet 131 can flow to the first part 1212, thereby prolonging the flow path of the steam in the steam cooling chamber 121 and improving the heat dissipation effect of the steam in the steam cooling chamber 121, thereby facilitating to reduce the temperature of the steam discharged from the steam humidifying device 100 and reduce the risk of the user being scalded by the steam.

[0073] Alternatively, the air outlet pipe 130 can be arranged at the center position of the steam cooling chamber 121, and then the part of the steam cooling chamber 121 farthest from the air outlet pipe 130 is defined as the first part 1212, for example, the inner wall 1211 of the steam cooling chamber 121 at the four top corners in the projection plane of the steam cooling chamber 121 in the axial direction of the air outlet pipe 130 can be defined as the first part 1212, and the air outlet 131 can be provided with four air outlets 131, and the four air outlets 131 can be arranged towards the first part 1212 respectively, so as to prolong the flow path of the steam in the steam cooling chamber 121 and improve the heat dissipation effect of the steam in the steam cooling chamber 121, thereby reducing the temperature of the steam discharged from the steam humidifying device 100.

[0074] It can be understood that the shape of the steam cooling chamber 121, the number of air outlets 131 and the arrangement position of the air outlet pipe 130 are only examples for facilitating the description and cannot be understood as a limitation of the present application. The shape of the steam cooling chamber 121, the number of air outlets 131 and the arrangement position of the air outlet pipe 130 can be determined according to actual production requirements, which are not limited herein.

[0075] In combination with Figure 11 and Figure 12 , through the simulation analysis and comparison of the temperature field of the steam humidifying device 100 and the related technology steam humidifying device, it can be seen that the temperature of the steam discharged from the steam humidifying device 100 is lower than that of the steam discharged from the steam humidifying device with only one air outlet in the related technology.

[0076] Specifically, as shown in A of Figure 11 and C of Figure 12 , the steam in the related technology steam humidifying device forms a relatively thick steam beam after being discharged from the air outlet, and the temperature and speed in the center area of the steam beam are relatively high. When the steam impacts the bottom wall and the side wall of the steam cooling chamber, it is directly discharged through the open end of the steam cooling chamber, resulting in high steam temperature outside the steam humidifying device. Referring to B of Figure 11 and D of Figure 12 , compared with the steam humidifying device in the related technology, the area of high-temperature steam of the steam humidifying device 100 of the present application is significantly reduced, and the steam temperature outside the steam humidifying device 100 is significantly lower than that of the steam humidifying device in the related technology.

[0077] Through further analysis and calculation, the temperature of the steam humidifying device 100 at the air outlet 131 of the present application is more than 2℃ lower than that of the steam humidifying device at the air outlet in the related technology.

[0078] In combination with Figures 1 to 3 andFigure 8 and Figure 9 In some embodiments of the present application, the air outlet pipe 130 is arranged perpendicularly to the bottom wall 1213 of the steam cooling chamber 121, and the air outlet pipe 130 is arranged away from the geometric center of the bottom wall 1213 of the steam cooling chamber 121, that is, the air outlet pipe 130 is arranged relatively close to the inner circumferential wall 1211 of the steam cooling chamber 121, and since at least one of the plurality of air outlets 131 on the air outlet pipe 130 is arranged opposite to the first portion 1212, arranging the air outlet pipe 130 away from the geometric center of the bottom wall 1213 of the steam cooling chamber 121 is conducive to further increasing the distance between the first portion 1212 and the air outlet 131 arranged opposite to it, thereby facilitating further extension of the flow path of the steam discharged by the air outlet 131 arranged opposite to the first portion 1212 within the steam cooling chamber 121, improving the heat dissipation effect of the steam, and reducing the temperature of the steam discharged by the steam humidifying device 100.

[0079] In combination with Figures 4 to 6 In some embodiments of the present application, the air outlet pipe 130 is provided with two air outlets 131, and the included angle α formed by the center lines of the two air outlets 131 satisfies the relationship: 30°≤α≤50°.

[0080] Exemplarily, one of the two air outlets 131 is arranged opposite to the first portion 1212, and the included angle α formed by the center lines of the two air outlets 131 satisfies the relationship: 30°≤α≤50°, so as to prevent the steam discharged by the two air outlets 131 from interfering with each other or gathering, and simultaneously facilitate preventing the other one of the two air outlets 131 (i.e., the air outlet 131 of the two air outlets 131 which is not arranged opposite to the first portion 1212) from being too close to the inner circumferential wall 1211 of the steam cooling chamber 121, when the other one of the two air outlets 131 is too close to the inner circumferential wall 1211 of the steam cooling chamber 121, the steam discharged from the air outlet 131 will directly flow along the inner circumferential wall 1211 of the steam cooling chamber 121, and its flow effect in the steam cooling chamber 121 is limited, resulting in poor heat exchange effect of the steam in the steam cooling chamber 121, in addition, it is conducive to realizing that the included angle of the first wall 138 of the two guide walls 137 defining the air outlet 131 is an acute angle, thereby facilitating ensuring the breaking effect of the breaking portion 136.

[0081] Therefore, by making the included angle a formed by the center lines of the two gas outlets 131 satisfy the relationship: 30°≤a≤50, the flow effect of the steam discharged by the two gas outlets 131 in the steam cooling chamber 121 is improved, thereby improving the heat exchange effect of the steam, reducing the temperature of the steam discharged by the steam humidifying device 100, and ensuring the sharpness of the bubble breaking part 136, improving the bubble breaking effect of the bubble breaking part 136, ensuring that the bubbles can break in the gas outlet pipe 130, and reducing the noise generated when the steam humidifying device 100 operates.

[0082] In combination Figures 1 to 3 and Figure 8 and Figure 9 In some embodiments of the present application, the steam cooling chamber 121 includes a first side wall 1214 located on one side of the steam cooling chamber 121 in the width direction and extending in a straight line, and the gas outlet pipe 130 is arranged close to the first side wall 1214.

[0083] Exemplarily, the inner circumferential wall 1211 of the steam cooling chamber 121 includes a first side wall 1214, and the orthographic projection of the first side wall 1214 in the axial direction parallel to the gas outlet pipe 130 extends in a straight line, and the gas outlet pipe 130 is arranged close to the first side wall 1214, so as to realize the arrangement of the gas outlet pipe 130 deviating from the geometric center of the bottom wall 1213 of the steam cooling chamber 121, which is beneficial to further increase the distance between the first part 1212 and the gas outlet 131 arranged opposite to it, thereby further prolonging the flow path of the steam discharged by the gas outlet 131 arranged opposite to the first part 1212 in the steam cooling chamber 121, improving the heat dissipation effect of the steam, and reducing the temperature of the steam discharged by the steam humidifying device 100.

[0084] In combination Figures 1 to 3 and Figure 8 and Figure 9 In further embodiments of the present application, in the axial direction parallel to the gas outlet pipe 130, the orthographic projection plane of the steam cooling chamber 121 can be arranged in a substantially rectangular shape, and the inner circumferential wall 1211 of the steam cooling chamber 121 on the other side in the width direction of the steam cooling chamber 121 except the first side wall 1214 and the inner circumferential wall 1211 on both sides in the length direction of the steam cooling chamber 121 are arc-shaped transitions, which is beneficial to increase the area of the steam cooling chamber 121, improve the heat dissipation effect of the steam in the steam cooling chamber 121, and improve the smoothness of the steam flowing in the steam cooling chamber 121, reduce the generation of resistance and eddy current.

[0085] In combination Figures 1 to 3 and Figure 9In some embodiments of the utility model, the steam humidifying equipment 100 satisfies the relationship formula: 0°≤γ≤45°.

[0086] Exemplarily, one of the plurality of air outlets 131 is arranged close to the first side wall 1214 compared with the rest of the air outlets 131, and the center line of the air outlet 131 arranged close to the first side wall 1214 is arranged at an angle with the first side wall 1214, defining the angle as γ, and γ satisfies 0°≤γ≤45°, which is beneficial to prevent the distance between the air outlet 131 arranged close to the first side wall 1214 in the plurality of air outlets 131 and the first side wall 1214 from being too close. When the distance between the air outlet 131 arranged close to the first side wall 1214 in the plurality of air outlets 131 and the first side wall 1214 is too close, the steam discharged from the air outlet 131 will directly flow along the first side wall 1214, and the flow effect in the steam cooling chamber 121 is limited, which leads to poor heat exchange effect of the steam in the steam cooling chamber 121, and at the same time, it is beneficial to prevent the distance between the air outlet 131 arranged adjacent to the first side wall 1214 in the plurality of air outlets 131 and the inner circumferential wall 1211 of the steam cooling chamber 121 from being too close, thereby preventing the steam discharged from the rest of the air outlets 131 from having poor flow effect in the steam cooling chamber 121.

[0087] Therefore, by making 0°≤γ≤45°, it is beneficial to improve the flow effect of the steam in the steam cooling chamber 121, so that the steam can fully flow and fully exchange heat in the steam cooling chamber 121, reduce the temperature of the steam discharged from the steam humidifying equipment 100, prevent the steam from scalding the user, and improve the use safety of the steam humidifying equipment 100.

[0088] In combination Figure 3 and Figure 10 In some embodiments of the utility model, the opening direction of the air outlet 131 is inclinedly arranged towards the bottom wall 1213 of the steam cooling chamber 121, that is, the center line of the air outlet 131 is arranged at an angle with the center axis of the air outlet pipe 130, and the angle is less than 90°, which is beneficial to make most of the steam discharged from the air outlet 131 flow towards the bottom wall 1213 of the steam cooling chamber 121, and the steam flowing towards the bottom wall 1213 of the steam cooling chamber 121 can flow along the bottom wall 1213 of the steam cooling chamber 121. The open end of the steam cooling chamber 121 can be located above the bottom wall 1213, and the steam can further flow upwards and be discharged through the open end of the steam cooling chamber 121.

[0089] Therefore, by tilting the opening direction of the air outlet 131 towards the bottom wall 1213 of the steam cooling chamber 121, the flow effect of the steam in the steam cooling chamber 121 is improved, the flow path of the steam is prolonged, and the steam can be fully cooled in the steam cooling chamber 121, thereby reducing the temperature of the steam discharged from the steam humidifying device 100.

[0090] In combination with Figure 4 , Figure 5 and Figure 7 , in some embodiments of the present application, an included angle β is formed between the center line of the air outlet 131 and the central axis of the air outlet pipe 130, and β satisfies: 45°≤β<90°, which is beneficial to fully flow the steam in the steam cooling chamber 121, improve the heat dissipation effect of the steam, and reduce the temperature of the steam discharged from the steam humidifying device 100, thereby reducing the risk of the steam scalding the user.

[0091] When β<45°, the opening direction of the air outlet 131 is too inclined towards the bottom wall 1213 of the steam cooling chamber 121, which is easy to cause the steam discharged from the air outlet 131 to hit the bottom wall 1213 of the steam cooling chamber 121 and be reflected to the open end of the steam cooling chamber 121. It can also be understood that when β<45°, the flow path of the steam in the steam cooling chamber 121 is short, thereby causing poor cooling effect of the steam, and further causing the temperature of the steam discharged from the steam humidifying device 100 to be too high; when β>90°, the opening direction of the air outlet 131 is relatively close to the open end of the steam cooling chamber 121, which causes the steam discharged from the air outlet 131 to flow out directly through the open end of the steam cooling chamber 121, thereby causing poor cooling effect of the steam, and further causing the temperature of the steam discharged from the steam humidifying device 100 to be too high.

[0092] In further embodiments of the present application, β satisfies: 45°≤β≤85°, which is beneficial to fully flow the steam in the steam cooling chamber 121, improve the heat dissipation effect of the steam, and reduce the temperature of the steam discharged from the steam humidifying device 100, thereby reducing the risk of the steam scalding the user.

[0093] It can be understood that β can be any value between 45° and 85°, for example, β can be 45°, 50°, 57°, 80° or 85°, and the specific value of β can be determined according to actual production requirements, which is not limited here.

[0094] In combination with Figure 3 and Figure 10In some embodiments of the present application, the top end of the air outlet pipe 130 is spaced apart from the open end of the steam cooling chamber 121 in the height direction of the air outlet pipe 130, which is conducive to spacing the air outlet 131 from the open end of the steam cooling chamber 121, thereby preventing the steam from being directly discharged through the open end of the steam cooling chamber 121 after being discharged from the air outlet 131, and facilitating the steam to flow fully in the steam cooling chamber 121, thereby improving the cooling effect of the steam. At the same time, by spacing the top end of the air outlet pipe 130 from the open end of the steam cooling chamber 121, the installation of the air outlet grille 122 described below is prevented from being interfered by the air outlet pipe 130, thereby improving the assembly convenience of the air outlet grille 122.

[0095] In some embodiments, the air outlet 131 is spaced apart from the bottom wall 1213 of the steam cooling chamber 121 in the height direction of the air outlet pipe 130, which prevents the bottom wall 1213 of the steam cooling chamber 121 from interfering with the smoothness of the steam being discharged from the air outlet 131, and facilitates the flow effect of the steam in the steam cooling chamber 121.

[0096] Referring to Figure 7 In some embodiments of the present application, the height of the air outlet pipe 130 is defined as L1, the distance between the lowest end of the air outlet 131 and the bottommost end of the air outlet pipe 130 is defined as L2, and the steam humidifying device 100 satisfies the relationship: 0.5≤L2 / L1≤0.9.

[0097] It should be noted that the "height of the air outlet pipe 130" can be understood as the dimension of the air outlet pipe 130 in the axial direction thereof.

[0098] Exemplarily, in the axial direction of the air outlet pipe 130, the distance between the position where the air outlet 131 is farthest away from the steam cooling chamber 121 and the bottommost end of the air outlet pipe 130 (i.e., the first end 132 of the air outlet pipe 130) is L2, and 0.5≤L2 / L1≤0.9, which is conducive to ensuring the size of the bubble breaking space 135, reducing the risk of bubbles being discharged from the air outlet pipe 130 and breaking outside the air outlet pipe 130, thereby reducing the noise generated by the steam humidifying device 100, and preventing the bottom wall 1213 of the steam cooling chamber 121 from interfering with the smoothness of the steam being discharged from the air outlet 131.

[0099] Preferably, the steam humidifying device 100 satisfies: 0.7≤L2 / L1≤0.8, which is conducive to ensuring the size of the bubble breaking space 135, and is conducive to further preventing the air outlet 131 from being too close to the bottom wall 1213 of the steam cooling chamber 121 due to the air outlet 131 being too close to the first end 132 of the air outlet pipe 130, thereby being conducive to ensuring the smoothness of the steam when being discharged from the air outlet 131.

[0100] It can be understood that the specific sizes of L1 and L2 can be adjusted according to the depth of the steam cooling chamber 121 (i.e. the size of the steam cooling chamber 121 in the axial direction parallel to the air outlet pipe 130) and the temperature field distribution, which is not specifically limited here.

[0101] In combination with Figure 7 and Figure 10 In some embodiments of the utility model, the height of the air outlet pipe 130 is defined as L1, the maximum distance between the top end of the air outlet pipe 130 and the bottom wall 1213 of the steam cooling chamber 121 is defined as d, and the steam humidifying device 100 satisfies the relationship: 0.4≤L1 / d≤0.8.

[0102] Exemplarily, the cover assembly 120 is provided with a pouring anti-leakage structure 160 opposite to the air outlet pipe 130, when the steam humidifying device 100 is poured, the pouring anti-leakage structure 160 can slide and block the communication between the air outlet pipe 130 and the steam generating cavity 111, so as to prevent the high-temperature water in the steam generating cavity 111 from leaking through the air outlet pipe 130, reduce the risk of user scalding, thereby improving the use safety of the steam humidifying device 100, by making the steam humidifying device 100 satisfy the relationship: 0.4≤L1 / d≤0.8, the air outlet pipe 130 can avoid the pouring anti-leakage structure 160, facilitating the arrangement of the pouring anti-leakage structure 160 on the cover assembly 120, and being conducive to ensuring that the air outlet pipe 130 has enough space to arrange the bubble breaking space 135 and the air outlet 131.

[0103] In combination with Figures 8 to 10 In some embodiments of the utility model, the cover assembly 120 further comprises an air outlet grille 122, which is arranged at the open end of the steam cooling chamber 121.

[0104] The air outlet grille 122 is formed with a plurality of connecting ports communicating with the steam cooling chamber 121 and the external space, the steam in the steam cooling chamber 121 can be discharged into the external space through the connecting ports on the air outlet grille 122, so as to improve the humidity of the external space, at the same time, by arranging the air outlet grille 122, it is conducive to reducing the risk of foreign matter (such as dust, etc.) falling into the steam cooling chamber 121, and is conducive to improving the cleanliness of the steam cooling chamber 121.

[0105] In combination with Figure 3 andFigure 10 In some embodiments of the present application, the cover assembly 120 is provided with a steam flow space 123, and the steam flow space 123 is in communication with the steam generating cavity 111 and the air outlet pipe 130 respectively.

[0106] For example, the steam generated in the steam generating cavity 111 can first flow into the steam flow space 123, and the steam can be preliminarily cooled in the steam flow space 123, and then the steam flows from the steam flow space 123 into the air outlet pipe 130 and is discharged into the steam cooling chamber 121 through the air outlet 131 for further cooling.

[0107] Therefore, by providing the steam flow space 123 in the cover assembly 120, the flow path of the steam is further prolonged, the cooling effect of the steam is improved, and the temperature of the steam discharged from the steam humidifying device 100 is reduced.

[0108] In combination with Figure 3 , Figure 8 and Figure 10 In some embodiments of the present application, the cover assembly 120 comprises a first cover body 124, a second cover body 125 and a third cover body 126, the first cover body 124 is formed with a steam inlet 1241 in communication with the steam generating cavity 111, the second cover body 125 is arranged on the side of the first cover body 124 away from the steam generating cavity 111, the second cover body 125 and the first cover body 124 define a steam flow space 123 in communication with the steam inlet 1241, and the second cover body 125 is formed with a communication port 150, the air outlet pipe 130 is in communication with the communication port 150, and the third cover body 126 is arranged on the side of the second cover body 125 away from the first cover body 124, and the third cover body 126 is formed with the steam cooling chamber 121.

[0109] For example, the first cover body 124 can be formed with a plurality of steam inlets 1241 penetrating the first cover body 124 in the axial direction parallel to the air outlet pipe 130, the steam generated in the steam generating cavity 111 can flow into the steam flow space 123 formed between the second cover body 125 and the first cover body 124 through the steam inlets 1241, and the second cover body 125 is formed with communication ports 150 in communication with the steam flow space 123 respectively, the steam entering the steam flow space 123 can enter the air outlet pipe 130 through the communication ports 150, and further discharged into the steam cooling chamber 121 through the air outlet 131 on the air outlet pipe 130, and the steam is cooled in the steam cooling chamber 121 and then discharged into the external space through the air outlet grille 122 to improve the humidity of the external space.

[0110] The air outlet pipe 130 is arranged on the second cover body 125 or the third cover body 126 and extends into the steam cooling chamber 121.

[0111] For example, the air outlet pipe 130 can be mounted on the second cover 125 so as to communicate with the communication port 150 arranged on the second cover 125, and the air outlet pipe 130 can pass through the third cover 126 and extend into the steam cooling chamber 121 so as to discharge steam into the steam cooling chamber 121; or the air outlet pipe 130 can be arranged on the third cover 126 directly, and the first end 132 of the air outlet pipe 130 can be arranged opposite to and communicated with the communication port 150 so as to facilitate the installation of the air outlet pipe 130 and the communication between the air outlet pipe 130 and the communication port 150.

[0112] It can be understood that the specific installation position of the air outlet pipe 130 can be determined according to actual production requirements, which is not limited here.

[0113] As shown in the drawings, in some embodiments of the utility model, the third cover 126 is formed with a mounting boss 1261, the mounting boss 1261 is protruded from the bottom wall 1213 of the steam cooling chamber 121 to the direction of the open end of the steam cooling chamber 121, by arranging the mounting boss 1261, the air outlet pipe 130 can be positioned and mounted on the cover assembly 120, which is beneficial to improve the installation convenience of the air outlet pipe 130, and the mounting boss 1261 can avoid the structure arranged on the side of the third cover 126 close to the steam generating cavity 111 in the cover assembly 120, which is beneficial to improve the assembly convenience of the cover assembly 120. Figure 10 Further, the air outlet pipe 130 is arranged corresponding to the mounting boss 1261 and passes through the top wall of the mounting boss 1261, that is, the air outlet pipe 130 is arranged at the mounting boss 1261, and the first end 132 of the air outlet pipe 130 is arranged between the third cover 126 and the second cover 125 so as to communicate with the communication port 150, and the second end 133 of the air outlet pipe 130 passes through the mounting boss 1261 and extends into the steam cooling chamber 121 so as to communicate the air outlet 131 with the steam cooling chamber 121, thereby facilitating the steam to flow into the steam cooling chamber 121.

[0114] Referring to

[0115] In some embodiments of the utility model, the air outlet 131 is located in the steam cooling chamber 121, and the minimum distance h between the air outlet 131 and the top wall of the mounting boss 1261 satisfies: 3mm≤h≤5mm, which is beneficial to improve the flow effect of the steam in the steam cooling chamber 121, thereby improving the heat dissipation effect of the steam. Figure 10

[0116] ​When h<3mm, the distance between the air outlet 131 and the top wall of the mounting boss 1261 is too close, which is easy to cause the steam to impact the top wall of the mounting boss 1261 after being discharged from the air outlet 131 and reflect to the air outlet grille 122, thereby causing poor heat dissipation effect of the steam; when h>5mm, it is easy to cause the steam to directly pass through the air outlet grille 122 and be discharged, thereby causing poor heat dissipation effect of the steam.

[0117] In some embodiments, the distance between the air outlet 131 and the top wall of the mounting boss 1261 can be 3mm, 5mm, etc., and the specific distance between the air outlet 131 and the top wall of the mounting boss 1261 is not limited here.

[0118] Since the top wall of the mounting boss 1261 protrudes from the bottom wall 1213 of the steam cooling chamber 121 to the open end of the steam cooling chamber 121, the distance between the air outlet 131 and the top wall of the mounting boss 1261 is less than the distance between the air outlet 131 and the bottom wall 1213 of the steam generating cavity 111, which is beneficial to further prolong the flow path of the steam in the steam cooling chamber 121 and improve the cooling effect of the steam.

[0119] For example, the maximum distance between the air outlet 131 and the bottom wall 1213 of the steam cooling chamber 121 can be 20mm, 21mm or 23mm, etc., and the specific maximum distance between the air outlet 131 and the bottom wall 1213 of the steam cooling chamber 121 can be determined according to the depth of the steam cooling chamber 121 and the actual production requirements, which is not limited here.

[0120] As shown in Figure 10 In some embodiments of the present application, a pouring anti-leakage structure 160 is arranged opposite to the communication port 150 between the first cover 124 and the second cover 125, when the steam humidifying device 100 is poured, the pouring anti-leakage structure 160 can slide to block the communication port 150, preventing the steam and the high-temperature water in the steam generating cavity 111 from leaking through the communication port 150 and the air outlet pipe 130, reducing the risk of scalding the user, thereby improving the use safety of the steam humidifying device 100.

[0121] And since the pouring anti-leakage structure 160 needs a certain arrangement space, the part of the second cover 125 corresponding to the pouring anti-leakage structure 160 needs to be protruded towards the third cover 126 to avoid the pouring anti-leakage structure 160, and the mounting boss 1261 on the third cover 126 can avoid the protruding part on the second cover 125 to prevent the mutual interference between the third cover 126 and the second cover 125, thereby improving the assembly convenience of the cover assembly 120.

[0124] In some other embodiments, the second cover body 125 is formed with a plug-in part 140, the plug-in part 140 can be formed as a plug-in protrusion, the air outlet pipe 130 can be plug-in matched with the plug-in protrusion and communicated with the communicating port 150, thereby realizing the assembly of the air outlet pipe 130 and the second cover body 125.

[0125] It can be understood that the arrangement position of the plug-in part 140 and the specific structure of the plug-in part 140 can be determined according to actual production requirements, which is not limited here, as long as the assembly reliability of the air outlet pipe 130 is ensured.

[0127] In some further embodiments, a press switch 170 is further arranged on the cover assembly 120, the press switch 170 can be transmission matched with the locking assembly to drive the locking assembly to release the state of locking the cover assembly 120 and the steam generation main body 110, so as to facilitate the user to open the steam humidifying equipment 100 and clean the steam generation cavity 111.

[0128] In some embodiments of the utility model, a backflow hole is further arranged on the cover assembly 120 and communicated with the steam generation cavity 111 and the steam cooling chamber 121, when the steam is condensed in the steam cooling chamber 121, the steam can be backflowed into the steam generation cavity 111 through the backflow hole, so as to realize the recycling of the condensed water.

[0129] In combination with Figures 8 to 10In further embodiments of the present application, the backflow hole is provided with a backflow member 180, when the steam humidifying device 100 is tilted, the backflow member 180 can slide to block the backflow hole, preventing the high-temperature water in the steam generating cavity 111 from leaking through the backflow hole, which is conducive to improving the use safety of the steam humidifying device 100.
