Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more specifically, to a humidifier. Background Technology

[0002] In most related solutions, humidifiers have a dedicated water filling channel inside, so when users add water from the top, the water will not flow through the air duct and the top surface of the evaporative cooling pad. However, when the humidifier directly uses the air duct opening as the water inlet, how to solve the water drainage problem between the air duct and the evaporative cooling pad, and ensure that the water added by the user does not flow outside the machine, has become an urgent problem to be solved. Summary of the Invention

[0003] The present invention aims to at least solve the problem of how to drain water between the air duct and the wet curtain when the humidifier directly uses the air duct opening as the water inlet in the prior art or related art.

[0004] Therefore, the object of the present invention is to provide a humidifier.

[0005] To achieve the above objectives, the first aspect of the present invention provides a humidifier, comprising: a bottom assembly including a water tank, a wet curtain, and an air inlet; an upper assembly detachably connected to the bottom assembly, including an air outlet, an upper air duct, and a fan assembly located within the upper air duct, wherein the fan assembly enables air from outside the bottom assembly to enter through the air inlet, pass through the wet curtain and the upper air duct, and then exit through the air outlet; and a guide member disposed on the upper assembly, wherein a first end of the guide member communicates with the upper air duct, and a second end of the guide member is disposed on the inner side of the outer side wall of the wet curtain; wherein the humidifier can also add water through the air outlet, and the water added through the air outlet can flow into the water tank through the upper air duct, the guide member, and the wet curtain.

[0006] The humidifier provided by the technical solution of the present invention includes a bottom assembly and an upper assembly, that is, the humidifier has a two-part structure. The upper assembly and the bottom assembly are detachably connected. The upper assembly includes an upper air duct, an air outlet, and a fan assembly. The fan assembly is installed in the upper air duct to create negative pressure, allowing air from outside the bottom assembly to enter through the air inlet, pass through the evaporative cooling pad, and exit through the air outlet. The bottom assembly includes a water tank, an evaporative cooling pad, and an air inlet. Under the action of the fan assembly, outside air can pass through the air inlet and through the evaporative cooling pad to be humidified. The humidified air can then enter the upper assembly under the action of the fan assembly and exit through the upper air duct of the upper assembly, thereby humidifying the air in the environment. The water tank is mainly used to supply water to the evaporative cooling pad to humidify the air passing through it. In this solution, the upper assembly mainly integrates major components such as a motor, fan, and electronic control board. The bottom assembly mainly consists of washable structures such as the evaporative cooling pad and water tank. This design allows the upper components to be completely removed from the humidifier before cleaning, and then the bottom components can be cleaned. For example, at least the wet curtain and water tank at the bottom can be cleaned, thus increasing the number of parts of the humidifier that can be cleaned and improving the cleaning effectiveness.

[0007] Meanwhile, a flow guide is also provided on the upper component. The first end of the flow guide connects to the upper air duct, and the second end corresponds to the inner side of the outer wall of the evaporative cooling pad. That is, the flow guide corresponds to the internal space of the evaporative cooling pad or to its top surface, but it cannot be positioned on the outside of the pad. This design allows for airflow between the upper air duct and the evaporative cooling pad, ensuring that when water is added through the air outlet, the water flows through the upper air duct, the flow guide, and the evaporative cooling pad into the water tank, preventing water from flowing to the outside of the evaporative cooling pad.

[0008] In any of the above embodiments, optionally, the upper component includes a volute that forms an upper air duct. The air inlet end of the volute is provided with a drain trough, and a drain outlet is provided on the side of the drain trough near the center of the upper air duct. The drain outlet is located on the inner side of the outer wall of the wet curtain along the radial direction of the fan component.

[0009] In this embodiment, the volute casing guides the airflow. A water trough is provided so that water added from the upper air duct can be stored in the trough before being discharged from the drain outlet. The water trough gives the volute casing a certain water collection capacity. This ensures that when water is added through the air outlet, the water is first stored in the trough, preventing water from flowing too quickly and overflowing onto the outside of the wet curtain when water is added through the air outlet.

[0010] Optionally, the drain outlet is located on the side of the drain trough near the center of the upper air duct.

[0011] In this embodiment, the drain outlet is located on the inner side, so that the water in the drain tank can drain from a position close to the inner side of the wet curtain. This makes it easier for the water to flow from the air passage in the middle of the wet curtain to the bottom of the wet curtain, and then to the water tank. This improves the smoothness of drainage and reduces the probability of water leakage when adding water through the air outlet.

[0012] In any of the above embodiments, optionally, along the radial direction of the fan assembly, the height of the inner bottom wall of the drain tank gradually decreases from the outside to the inside, and the drain outlet is located at the lowest position of the inner bottom wall of the drain tank.

[0013] In this embodiment, the inner bottom wall of the drain tank is inclined, with the outer side higher than the inner side, and the drain outlet is located at the lowest point on the inner side. This allows all the water in the drain tank to be discharged through the drain outlet, thus emptying the drain tank and preventing residual water from remaining. If water accumulates in the drain tank, when water is added through the air outlet, water that does not flow down the volute wall will impact the accumulated water, causing it to splash upwards. This poses a risk of water ingress at the connection between the fan impeller and the fan shaft. By placing the drain outlet at the lowest point on the inner side, residual water can be effectively avoided, thereby reducing the risk of water ingress at the connection between the fan impeller and the fan shaft.

[0014] In any of the above embodiments, optionally, the air inlet end of the volute also includes an air inlet hole, a water trough is arranged around the air inlet hole, and there are multiple water outlets, which are spaced apart along the circumference of the fan assembly; the side wall of the water trough near the air inlet hole is a first side wall, and the height of the first side wall gradually increases from the outside to the inside.

[0015] In this embodiment, an upper air duct is formed inside the volute, and an inlet hole for the upper air duct is provided at the bottom of the volute. A drainage trough with multiple drain outlets is also provided at the bottom of the volute to increase the drainage speed. By making the first sidewall inclined, the airflow can be guided through the first sidewall, avoiding abrupt changes in the direction of the airflow and thus preventing wind energy loss.

[0016] In any of the above embodiments, optionally, the flow guide includes a flow guide rib, the first end of which is disposed on the outer bottom wall of the lower water tank, the second end of which extends toward the wet curtain and the end of the second end of which is located on the inner side of the outer wall of the wet curtain; wherein the flow guide rib is inclined or vertically disposed relative to the height direction of the humidifier.

[0017] In this embodiment, the lower end of the guide rib is located on the inner side of the outer wall of the wet curtain, which can prevent water from flowing to the outer side of the wet curtain. The guide rib gradually slopes inward from top to bottom, thus guiding the water as much as possible towards the center of the wet curtain, preventing water from flowing to the outer side and causing water leakage.

[0018] In any of the above embodiments, optionally, the humidifier further includes: a wet curtain cover, installed on top of the wet curtain, the wet curtain cover being provided with a first annular baffle, the first annular baffle being located outside the flow guide, and the top of the first annular baffle being higher than the end of the second end of the flow guide.

[0019] In this embodiment, an upper cover for the evaporative cooling pad is provided above it. The upper cover has a hollow structure in the middle, forming an air passage. Air discharged from the evaporative cooling pad can enter the upper component through the air passage. Simultaneously, the upper cover is also provided with a first annular baffle. The first annular baffle is located outside the guide member and is positioned higher than the bottom of the guide member. This creates a water-blocking structure outside the guide member, giving the upper cover a certain water retention capacity. This allows the first annular baffle to partially obstruct the water flow when it is too rapid, reducing the risk of water leakage.

[0020] In any of the above embodiments, optionally, the surface of the wet curtain cover away from the wet curtain forms an inclined guide surface from the first annular baffle to the center of the wet curtain, and along the radial direction of the wet curtain, the position of the inclined guide surface in the height direction of the wet curtain gradually decreases from the first annular baffle to the center of the wet curtain.

[0021] In this technical solution, the surface of the wet curtain cover located inside the first annular baffle is a downwardly inclined guide surface, which allows the water on the wet curtain cover to fall naturally by gravity, thereby improving the smoothness and speed of water drainage from the wet curtain cover.

[0022] In any of the above embodiments, the humidifier may optionally further include: a second sealing element disposed between the first annular baffle and the lower water tank to seal the gap between the first annular baffle and the lower water tank.

[0023] In this embodiment, the wet curtain cover is also provided with a first annular baffle. During installation, a second sealing element is provided between the first annular baffle and the outer shell assembly to seal the gap between the first annular baffle and the outer shell assembly. This ensures that the wet curtain cover and the upper assembly are in sealed contact. In this way, even if the water flow on the wet curtain cover is too rapid, causing the water level on the wet curtain cover to rise, water is less likely to leak from the wet curtain cover and the upper assembly to the outside of the machine, greatly reducing the problems of water overflow and excessive water flow.

[0024] Specifically, when water flows over the top cover of the evaporative cooling pad, the water flows inwards. If the water flow is too rapid, it may reach or submerge the first annular baffle. In this case, the second seal, which contacts the first annular baffle, further prevents water from overflowing. Through the two blocking mechanisms of the first annular baffle and the second seal, the problems of water overflow and excessive water flow are greatly reduced. Even if some water still overflows after being blocked, the impact force of this water flow has been buffered, and because this water lacks impact force, it cannot reach the outside of the machine. This prevents the humidifier from wetting the floor during use.

[0025] In any of the above embodiments, optionally, the upper component further includes: a fixed bracket installed between the wet curtain cover and the lower water tank, the fixed bracket having an installation groove on the side near the wet curtain cover to accommodate the second sealing element, the fixed bracket having one of a second limiting groove and a second limiting protrusion on the side away from the wet curtain cover, the lower water tank having the other of a second limiting groove and a second limiting protrusion on its outer bottom wall, the second limiting protrusion being limited within the second limiting groove.

[0026] In this embodiment, the upper component further includes a fixing bracket, which is installed at the bottom of the volute. The upper component can be detachably connected to the bottom component via the fixing bracket. A second seal is installed between the evaporative cooling pad cover and the fixing bracket to achieve a seal between them. Simultaneously, the fixing bracket and the volute can be positioned using a second limiting groove and a second limiting protrusion. The second limiting groove and the second limiting protrusion are in surface contact. This surface contact prevents water from entering the electrical compartment from the upper air duct enclosed by the volute.

[0027] Specifically, the second limiting groove and the second limiting protrusion are respectively set at the position of the lower water tank, that is, the second limiting groove and the second limiting protrusion are located on the outside of the guide rib.

[0028] In some embodiments, optionally, at least a portion of the second limiting groove or the second limiting protrusion on the fixed bracket is located at a height position higher than the top of the first annular baffle.

[0029] In this technical solution, the connection between the fixed bracket and the volute is positioned relatively high, so that only when the water level exceeds the top of the first annular baffle will it be able to submerge the sidewall of the second limiting protrusion or the second limiting groove. This design ensures that the water level will not easily exceed the connection between the fixed bracket and the volute, thereby further reducing the probability of water in the upper air duct seeping into the electrical compartment from the connection between the fixed bracket and the volute.

[0030] In any of the above embodiments, optionally, the first annular baffle and the wet curtain cover are an integral structure.

[0031] In any of the above embodiments, optionally, the first annular baffle is a protrusion formed by the upper cover of the wet curtain being recessed in the direction away from the wet curtain.

[0032] In this embodiment, by recessing the top cover of the wet curtain upward to form a protrusion, the first annular baffle can be quickly and easily processed on the top cover of the wet curtain, making the processing of the top cover of the wet curtain simpler and more convenient.

[0033] In any of the above embodiments, optionally, the bottom component further includes: a wet curtain support, the wet curtain being mounted on the wet curtain support, and a water distribution structure being provided on the wet curtain cover; a water pump for pumping water from the water tank to the water distribution structure, and the water distribution structure distributing the water onto the wet curtain; and a connecting hole being provided on the wet curtain cover, the connecting hole connecting the drain outlet and the water distribution structure.

[0034] In this embodiment, the evaporative cooling pad bracket supports the evaporative cooling pad to prevent it from being soaked in the water tank for extended periods. The evaporative cooling pad cover is installed at the bottom of the evaporative cooling pad. Water from the water tank is pumped to the evaporative cooling pad cover by a water pump, and then the water distribution structure on the cover distributes the water relatively evenly across the evaporative cooling pad. The evaporative cooling pad cover also has connecting holes, allowing at least a portion of the water from the drain outlet to enter the cover through the connecting structure. The water distribution structure then evenly distributes the water onto the evaporative cooling pad. This design ensures that some water enters the cover and falls onto the evaporative cooling pad while the user is adding water to the tank, thus wetting the pad. When the humidifier is started, the fan activates, and the airflow passes through the wetted pad to produce humidifying airflow, eliminating the need for a water pump to draw water onto the pad and wet it before humidification occurs.

Detailed Implementation

[0055] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0056] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0057] like Figures 1 to 16As shown, an embodiment of the first aspect of the present invention provides a humidifier, comprising: a bottom assembly 1, including a water tank 10, a wet curtain 12, and an air inlet 132; and an upper assembly 2, detachably connected to the bottom assembly 1, including an air outlet 22, an upper air duct 258, and a fan assembly 21 located within the upper air duct 258. The fan assembly 21 enables air from outside the bottom assembly 1 to enter through the air inlet 132, pass through the wet curtain 12 and the upper air duct 258, and then exit through the air outlet 22. The airflow path is as follows: Figure 4 As shown by the arrow in the image. Figure 13 As shown, the humidifier also includes: a guide member 5, which is disposed on the upper component 2. The first end of the guide member 5 is connected to the upper air duct 258, and the second end of the guide member 5 is disposed on the inner side of the outer side wall of the wet curtain 12. The humidifier can also add water through the air outlet 22. The water added from the air outlet 22 can flow into the water tank 10 through the upper air duct 258, the guide member 5 and the wet curtain 12.

[0058] The humidifier provided according to an embodiment of the present invention includes a bottom assembly 1 and an upper assembly 2, that is, the humidifier has a two-part structure. The upper assembly 2 and the bottom assembly 1 are detachably connected. The upper assembly 2 includes an upper air duct 258, an air outlet 22, and a fan assembly 21. The fan assembly 21 is installed inside the upper air duct 258 to create a negative pressure, allowing air from outside the bottom assembly 1 to enter through the air inlet 132, pass through the evaporative cooling pad 12, and exit through the air outlet 22. The bottom assembly 1 includes a water tank 10, an evaporative cooling pad 12, and an air inlet 132. Under the action of the fan assembly 21, outside air can pass through the air inlet 132 and through the evaporative cooling pad 12 to be humidified. The humidified air can then enter the upper assembly 2 under the action of the fan assembly 21 and exit through the upper air duct 258 of the upper assembly 2, thereby humidifying the air in the environment. The water tank is mainly used to supply water to the evaporative cooling pad 12 to humidify the air passing through it. In this design, the upper component 2 mainly integrates the motor 212, fan 214, and electronic control board. The bottom component 1 mainly consists of the evaporative cooling pad 12 and water tank 10, which are washable structures. With this setup, when the humidifier needs cleaning, the upper component 2 can be completely removed from the humidifier first, and then the bottom component 1 can be cleaned. For example, at least the evaporative cooling pad 12 and water tank 10 of the bottom component 1 can be cleaned, thus increasing the number of parts of the humidifier that can be cleaned and improving the cleaning effectiveness.

[0059] At the same time, such as Figure 13As shown, a guide member 5 is also provided on the upper component 2. The first end of the guide member 5 is connected to the upper air duct 258, and the second end of the guide member 5 is provided on the inner side of the outer wall of the wet curtain 12. That is, the guide member 5 is provided in the inner space of the wet curtain 12 or on the top surface of the wet curtain 12, but the guide member 5 cannot be provided on the outer side of the wet curtain 12. With this arrangement, the guide member 5 can guide the flow between the upper air duct 258 and the wet curtain 12. This allows the water added to the humidifier through the air outlet 22 to flow into the water tank 10 through the upper air duct 258, the guide member 5, and the wet curtain 12 when water is added through the air outlet 22. This ensures that the water added through the guide member 5 will not flow to the outer side of the wet curtain 12.

[0060] In any of the above embodiments, optionally, as Figure 2 , Figure 3 and Figure 13 As shown, the upper component 2 includes a volute 25, which forms an upper air duct 258. The air inlet end of the volute 25 is provided with a drain trough 256, and a drain outlet 259 is provided on the side of the drain trough 256 near the center of the upper air duct 258. The drain outlet 259 is located on the inner side of the outer wall of the wet curtain 12 along the radial direction of the fan component 21.

[0061] In this embodiment, the upper component 2 includes a volute 25, within which a fan assembly 21 is installed. The upper air duct 258 is enclosed by the volute 25, which guides the airflow. Furthermore, considering that the humidifier needs water added through the air outlet 22, this embodiment also includes a water trough 256 at the bottom of the volute 25. The water trough 256 is positioned around the air inlet 2582 of the volute 25. By providing the water trough 256, water added from the upper air duct 258 can be stored in the water trough 256 before being discharged from the drain outlet 259 of the water trough 256. By setting up the water tank 256, the volute 25 has a certain water collection capacity. When water is added through the air outlet 22, the added water can be stored in the water tank 256 first. This can prevent the water from flowing out of the wet curtain 12 in time when water is added through the air outlet 22 due to the large water flow.

[0062] In any of the above embodiments, optionally, as Figure 13 As shown, the drain outlet 259 is located on the side of the drain tank 256 near the center of the upper air duct 258.

[0063] In this embodiment, the drain outlet 259 is located on the side of the drain tank 256 near the center of the upper air duct 258, that is, the drain outlet 259 is located on the inner side. This allows the water in the drain tank 256 to drain from the position near the inner side of the wet curtain 12. This makes it easier for the water to flow from the air passage 82 in the middle of the wet curtain 12 to the bottom of the wet curtain 12, and then to the water tank 10. This improves the smoothness of drainage and reduces the probability of water leakage when adding water through the air outlet 22.

[0064] In any of the above embodiments, optionally, as Figure 13 As shown, along the radial direction of the fan assembly 21, the height of the inner bottom wall of the drain trough 256 gradually decreases from the outside to the inside, and the drain outlet 259 is located at the lowest position of the inner bottom wall of the drain trough 256.

[0065] In this embodiment, the inner bottom wall of the drain tank 256 is inclined, with the outer side higher than the inner side, and the drain outlet 259 is located at the lowest position on the inner side. This allows all the water in the drain tank 256 to be discharged through the drain outlet 259, thus draining the water from the drain tank 256 and preventing residual water from remaining in the drain tank 256. If water accumulates in the drain tank 256, when water is added through the air outlet 22, the water that does not flow down the wall of the volute 25 will impact the water in the drain tank 256, causing it to splash upwards. This poses a risk of water ingress at the connection between the fan impeller and the fan shaft. By placing the drain outlet 259 at the lowest position on the inner side, residual water can be effectively avoided, thereby reducing the risk of water ingress at the connection between the fan impeller and the fan shaft.

[0066] In any of the above embodiments, optionally, as Figure 2 and Figure 13 As shown, the air inlet end of the volute 25 also includes an air inlet hole 2582, a water tank 256 is arranged around the air inlet hole 2582, and there are multiple water outlets 259, which are spaced apart along the circumference of the fan assembly 21; the side wall of the water tank 256 near the air inlet hole 2582 is the first side wall, and the height of the first side wall gradually increases from the outside to the inside.

[0067] In this embodiment, an upper air duct 258 is formed inside the volute 25, and an inlet hole for the upper air duct 258 is provided at the bottom of the volute 25. A drainage trough 256 is also provided at the bottom of the volute 25, and multiple drain outlets 259 are provided in the drainage trough 256. The multiple drain outlets 259 can increase the drainage speed of the drainage trough 256. Exemplarily, the multiple drain outlets 259 are evenly spaced along the circumference of the fan assembly 21, thereby improving the uniformity of drainage in all directions of the upper air duct 258. The inner sidewall of the drainage trough 256 is a first sidewall, which gradually slopes upwards from the outside to the inside. By making the first sidewall inclined, the airflow can be guided through the first sidewall, avoiding abrupt reversal of the airflow and resulting in wind energy loss.

[0068] In any of the above embodiments, optionally, as Figure 13 As shown, the flow guide 5 includes a flow guide rib 52. The first end of the flow guide rib 52 is disposed on the outer bottom wall of the lower water tank 256, and the second end of the flow guide rib 52 extends toward the wet curtain 12 in a direction close to the wet curtain 12. The end of the second end of the flow guide rib 52 is located on the inner side of the outer side wall of the wet curtain 12. The flow guide rib 52 is inclined or vertically disposed relative to the height direction of the humidifier.

[0069] In this embodiment, guide ribs 52 can be provided on the outer bottom wall of the drain tank 256 to guide the water flow. Positioning the lower end of the guide ribs 52 on the inner side of the outer wall of the evaporative cooling pad 12 prevents water from flowing to the outside of the evaporative cooling pad 12. The guide ribs 52 can be inclined or vertical as needed. When inclined, the guide ribs 52 gradually slope inwards from top to bottom, guiding the water as much as possible towards the center of the evaporative cooling pad 12, preventing water from flowing to the outside of the evaporative cooling pad 12 and causing water leakage.

[0070] In any of the above embodiments, optionally, as Figure 4 , Figure 10 and Figure 13 As shown, the humidifier also includes: a wet curtain cover 8, which is installed on top of the wet curtain 12. The wet curtain cover 8 is provided with a first annular baffle 84, which is located outside the guide member 5, and the top of the first annular baffle 84 is higher than the end of the second end of the guide member 5.

[0071] In this embodiment, an upper cover 8 is provided above the wet curtain 12. The middle part of the upper cover 8 is hollow, thus forming an air passage 82. The air discharged from the wet curtain 12 can enter the upper component 2 through the air passage 82. At the same time, the upper cover 8 is also provided with a first annular baffle 84. The first annular baffle 84 is located outside the guide member 5 and is set higher than the bottom of the guide member 5. In this way, the first annular baffle 84 can form a water-blocking structure outside the guide member 52, so that the upper cover 8 has a certain water storage capacity. In this way, when the water flow is too fast, the first annular baffle 84 can block the water flow to a certain extent, thereby reducing the risk of water leakage.

[0072] In any of the above embodiments, optionally, as Figure 4 and Figure 13 As shown, the surface of the wet curtain cover 8 away from the wet curtain 12 forms an inclined guide surface 88 from the first annular baffle 84 to the center of the wet curtain 12. Along the radial direction of the wet curtain 12, the position of the inclined guide surface 88 in the height direction of the wet curtain 12 gradually decreases from the first annular baffle 84 to the center of the wet curtain 12.

[0073] In this embodiment, the surface of the wet curtain cover 8 located inside the first annular baffle 84 is a downwardly inclined guide surface 88, which allows the water on the wet curtain cover 8 to fall naturally by gravity, thereby improving the smoothness of water drainage from the wet curtain cover 8 and increasing the drainage speed of the wet curtain cover 8.

[0074] In any of the above embodiments, optionally, as Figure 13 As shown, the humidifier also includes a second sealing element 9, disposed between the first annular baffle 84 and the lower water tank 256, to seal the gap between the first annular baffle 84 and the lower water tank 256.

[0075] In this embodiment, the wet curtain cover 8 is also provided with a first annular baffle 84. During installation, a second sealing element 9 is provided between the first annular baffle 84 and the outer shell assembly 20 to seal the gap between the first annular baffle 84 and the outer shell assembly 20. This ensures that the wet curtain cover 8 and the upper assembly 2 are in sealed contact. In this way, even if the water flow on the wet curtain cover 8 is too rapid and the water level on the wet curtain cover 8 increases, water is less likely to leak from the wet curtain cover 8 and the upper assembly 2 to the outside of the machine, greatly reducing the problems of water overflow and excessive water flow.

[0076] Specifically, when water flows through the wet curtain cover 8, it flows towards the interior of the wet curtain 12. When the water flow is too rapid, it may reach the height of the first annular baffle 84 or submerge it. In this case, the second seal 9, which is in contact with the first annular baffle 84, will further block the water from overflowing. Through the two blocking mechanisms of the first annular baffle 84 and the second seal 9, the problems of water overflow and excessive water flow are greatly reduced. Even if there is still some overflow after the blocking, the impact force of this water flow has been buffered. Since this water does not have impact force, it cannot reach the outside of the machine, thus preventing the humidifier from wetting the ground during use.

[0077] In any of the above embodiments, optionally, as Figure 2 and Figure 13 As shown, the upper component 2 also includes: a fixing bracket 204, which is installed between the wet curtain cover 8 and the drain trough 256. The fixing bracket 204 has an installation groove on the side near the wet curtain cover 8 to accommodate the second sealing element 9. The fixing bracket 204 has one of a second limiting groove 2522 and a second limiting protrusion 2044 on the side away from the wet curtain cover 8. The other of the second limiting groove 2522 and the second limiting protrusion 2044 is provided on the outer bottom wall of the drain trough 256. The second limiting protrusion 2044 is limited within the second limiting groove 2522.

[0078] In this embodiment, the upper component 2 further includes a fixing bracket 204, which is installed at the bottom of the volute 25. The upper component 2 can be detachably connected to the bottom component 1 via the fixing bracket 204. A second sealing member 9 is installed between the wet curtain cover 8 and the fixing bracket 204 to achieve a seal between the fixing bracket 204 and the wet curtain cover 8. Simultaneously, the fixing bracket 204 and the volute 25 can also be positioned using a second limiting groove 2522 and a second limiting protrusion 2044. The second limiting groove 2522 and the second limiting protrusion 2044 are in surface contact. This surface contact prevents water within the upper air duct 258 enclosed by the volute 25 from entering the electrical compartment 24.

[0079] Specifically, the second limiting groove 2522 and the second limiting protrusion 2044 are respectively set at the position of the lower water tank 256, that is, the second limiting groove 2522 and the second limiting protrusion 2044 are located on the outside of the guide rib 52.

[0080] In some embodiments, optionally, such as Figure 13 As shown, at least a portion of the second limiting groove 2522 or the second limiting protrusion 2044 on the fixed bracket 204 is located at a height position higher than the top of the first annular baffle 84.

[0081] In this embodiment, the connection between the fixed bracket 204 and the volute 25 is positioned relatively high, so that only when the water level exceeds the top of the first annular baffle 84 will it be possible to submerge the sidewall of the second limiting protrusion 2044 or the second limiting groove 2522. This arrangement ensures that the water level generally does not easily exceed the connection between the fixed bracket 204 and the volute 25, thereby further reducing the probability that water in the upper air duct 258 will seep into the electrical compartment 24 from the connection between the fixed bracket 204 and the volute 25.

[0082] Optionally, the first annular baffle 84 and the wet curtain cover 8 are an integral structure. This increases the strength between the first annular baffle 84 and the wet curtain cover 8, thereby preventing separation between them.

[0083] In any of the above embodiments, optionally, as Figure 4 , Figure 10 and Figure 13 As shown, the upper cover 8 of the wet curtain is recessed upward to form a protrusion 86, which allows the first annular baffle 84 to be quickly and easily processed on the upper cover 8 of the wet curtain, making the processing of the upper cover 8 of the wet curtain simpler and more convenient.

[0084] In any of the above embodiments, optionally, as Figure 2 , Figure 10 and Figure 11 As shown, the bottom assembly 1 also includes a wet curtain support 11, which supports the installation of the wet curtain 12 to prevent the wet curtain 12 from being submerged in the water tank 10 for a long time. The wet curtain cover 8 is installed at the bottom of the wet curtain 12. Water in the water tank 10 can be pumped to the wet curtain cover 8 by the water pump 17, and then the water distribution structure of the wet curtain cover 8 distributes the water relatively evenly to the wet curtain 12. The wet curtain cover 8 is also provided with a connecting hole. Water discharged from the drain outlet 259 can enter the wet curtain cover 8 through the connecting structure at least partially. Then, the water distribution structure distributes the water evenly onto the wet curtain 12. With this setting, when the user adds water to the water tank 10, some water has already entered the wet curtain cover 8 and fallen onto the wet curtain 12, wetting the wet curtain 12. In this way, when the humidifier is started, the fan starts and the airflow can flow out through the wet wet curtain 12 to produce humidifying airflow, without having to wait for the water pump 17 to draw water onto the wet curtain 12 and wet the wet curtain 12 before the humidification effect is achieved.

[0085] Optionally, the second seal 9 includes at least one of a sponge, a silicone, and a rubber component. Of course, the second seal 9 can also be of other sealing forms.

[0086] In some embodiments, optionally, such as Figure 2 , Figure 3 and Figure 4As shown, an air passage 124 is formed in the middle of the wet curtain 12. The fan assembly 21 allows air from outside the bottom assembly 1 to enter through the air inlet 132, and then pass through the wet curtain 12, the air passage 124, and the upper air duct 258 before being discharged from the air outlet 22.

[0087] In some embodiments, optionally, such as Figure 2 and Figure 3 As shown, the volute 25 includes a motor bracket 254 and an air duct enclosure 252. The air duct enclosure 252 is mounted on a fixed bracket 204, and the motor bracket 254 is mounted on the end of the air duct enclosure 252 away from the fixed bracket 204. The two are sealed together to form an upper air duct 258.

[0088] In some embodiments, optionally, such as Figure 2 and Figure 3 As shown, the motor bracket 254 is sealed to the upper cover assembly 205. Specifically, a sealing silicone sealant is provided between the motor bracket 254 and the upper cover assembly 205. The motor bracket 254 has an annular groove to accommodate the sealing silicone sealant. The motor bracket 254 and the upper cover assembly 205 are fixed together with screws, causing the silicone sealant to deform and ensuring a seal between the upper cover assembly 205 and the motor bracket 254. This prevents water from flowing into the motor bracket 254 when the user adds water, thus preventing motor 212 malfunction.

[0089] In any of the above embodiments, optionally, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the humidifier also includes a power interface 302, which is installed on the upper component 2. This prevents water from entering the power interface 302 when cleaning the bottom component 1 of the humidifier. A first coupler 32 is located on the outer casing 20 and connected to the power interface 302. A second coupler 34 is located on the bottom component 1, such as on the wet curtain bracket 11. When the upper component 2 is connected to the bottom component 1, the first coupler 32 and the second coupler 34 are electrically connected, thus transmitting power from the upper component 2 to the bottom component 1, thereby powering the electrical components of the bottom component 1. Simultaneously, the electrical connection of the first coupler 32 and the second coupler 34 also enables signal transmission between the bottom component 1 and the upper component 2, thereby controlling the entire unit. For example, signals from the main control board 38 of the upper component 2 to control the water pump 17, and water level signals detected by the bottom component 1, can be transmitted through the first coupler 32 and the second coupler 34.

[0090] Optionally, such as Figures 6 to 11As shown, the bottom component 1 also includes: an air inlet grille 13, which is installed on the water tank 10 and arranged around the water tank 10 and the wet curtain 12. The air inlet grille 13 is provided with an air inlet hole 132 at the position corresponding to the wet curtain 12; the outer casing component 20 is detachably installed on the wet curtain bracket 11.

[0091] Furthermore, a filter screen is installed between the air inlet grille 13 and the evaporative cooling pad 12. The filter screen is used to filter the air passing through the evaporative cooling pad 12 to remove dust and other particles from the air. The filter screen can also be washed directly with water when cleaning the humidifier.

[0092] Among them, such as Figure 2 As shown, the fan assembly 21 includes a motor 212 and a fan 214. The motor 212 drives the fan 214 to rotate to create a negative pressure, so that air outside the air inlet grille 13 can enter through the air inlet grille 13, pass through the wet curtain 12, and be discharged from the air outlet 22.

[0093] In some embodiments, optionally, such as Figure 2 As shown, the conductive connection position of the first coupler 32 and the second coupler 34 is higher than the highest surface of the wet curtain bracket 11 in the height direction.

[0094] In some embodiments, optionally, such as Figure 2 , Figure 3 and Figure 4 As shown, the housing assembly 20 is provided with at least one first buckle 201, and the wet curtain bracket 11 is provided with at least one second buckle 111. The housing assembly 20 and the wet curtain bracket 11 are detachably connected by at least one first buckle 201 and at least one second buckle 111.

[0095] In some embodiments, optionally, such as Figure 2 , Figure 5 and Figure 7 As shown, at least one first buckle 201 includes at least one positioning groove 2012, and at least one second buckle 111 includes at least one positioning protrusion 1112. The positioning protrusion 1112 and the positioning groove 2012 correspond one-to-one. The positioning protrusion 1112 can be detachably inserted into the positioning groove 2012 so that the housing assembly 20 and the wet curtain bracket 11 can be detachably connected.

[0096] In some embodiments, optionally, a first coupler 32 is disposed within one of the positioning grooves 2012, and a second coupler 34 is disposed within one of the positioning protrusions 1112, corresponding to the first coupler 32. This arrangement combines the coupler and one of the positioning structures, simplifying the product structure. Furthermore, this arrangement allows the first coupler 32 and the second coupler 34 to mate simultaneously when the upper component 2 and the bottom component 1 are connected, eliminating the need for separate connection of the first coupler 32 and the second coupler 34, thus improving the user experience.

[0097] In some embodiments, optionally, such as Figure 5 , Figure 6 and Figure 7 As shown, the evaporative cooling pad bracket 11 includes multiple limiting flanges 112, which fold outwards along the radial direction of the bracket 11. A mating flange 134 is provided on the side of the air inlet grille 13 away from the water tank 10, and the limiting flanges 112 are positioned on the side of the mating flange 134 away from the water tank 10. During installation, the limiting flanges 112 can be placed against the mating flange 134, thereby achieving height-directed installation of the evaporative cooling pad bracket 11 and the air inlet grille 13. The evaporative cooling pad bracket 11 and the air inlet grille 13 are positioned and installed through the flange structure, facilitating disassembly. When cleaning is required, the evaporative cooling pad bracket 11 can be quickly disassembled, improving cleaning efficiency.

[0098] In some embodiments, optionally, such as Figure 5 , Figure 6 and Figure 7 As shown, a positioning protrusion 1112 is provided on each limiting flange 112 to achieve limiting installation between the evaporative cooling pad bracket 11 and the outer casing assembly 20. Providing the positioning protrusion 1112 on the limiting flange 112 makes the structure of the evaporative cooling pad bracket 11 more rational. Of course, the positioning protrusion 1112 may not be provided on the limiting flange 112.

[0099] In some embodiments, optionally, such as Figures 2 to 8 As shown, the multiple limiting flanges 112 include two first limiting flanges 1122, which are disposed on opposite sides of the wet curtain bracket 11. The positioning protrusions 1112 include first positioning protrusions 11122 disposed on the first limiting flanges 1122, and the first positioning protrusions 11122 are provided with handle structures.

[0100] In this embodiment, the interior of the second positioning protrusion 1112 can be configured as a hollow structure, and the hollow structure can be configured as an open structure, so that a groove structure can be formed on the positioning protrusion 1112 for use as a handle. When lifting or moving the wet curtain bracket 11, the groove structure on the positioning protrusion 1112 can be used as a handle structure for the wet curtain bracket 11 to facilitate lifting or moving the wet curtain bracket 11.

[0101] In some embodiments, such as Figure 8 and Figure 9 As shown, optionally, the limiting flange 112 is provided with one of a first limiting protrusion 113 and a first limiting groove 1342 on the side near the water tank 10, and the other of the first limiting protrusion 113 and the first limiting groove 1342 is provided on the side of the flange 134 away from the water tank 10, and the first limiting protrusion 113 is limited within the first limiting groove 1342.

[0102] In this embodiment, the first limiting protrusion 113 and the first limiting groove 1342 are used for limiting, which can ensure that there is no axial movement between the wet curtain bracket 11 and the air inlet grille 13, and make the connection between the two in the axial direction more reliable, thereby ensuring the stability of the installation of the wet curtain 12 and the wet curtain bracket 11.

[0103] In some embodiments, optionally, such as Figure 10 and Figure 11 As shown, the evaporative cooling pad 12 is detachably mounted on the evaporative cooling pad bracket 11. This arrangement allows the evaporative cooling pad 12 and the evaporative cooling pad bracket 11 to be cleaned separately, thereby ensuring the cleaning effect of the humidifier. In addition, this arrangement also facilitates the individual maintenance and replacement of the evaporative cooling pad 12 and the evaporative cooling pad bracket 11.

[0104] In some embodiments, optionally, such as Figure 2 , Figure 3 , Figure 15 and Figure 16 As shown, the bottom component 1 also includes: a water pump mounting bracket 15, mounted on the evaporative cooling pad bracket 11, and forming a sealed mounting cavity 16 with the evaporative cooling pad bracket 11; a water pump 17 (as shown in the image). Figure 3 As shown, a water pump 17 is installed in the water tank 10 to supply water to the wet curtain 12; a first circuit board 36 is installed in the sealed mounting cavity 16 and connected to the water pump 17 and the second coupler 34. The water pump mounting bracket 15 is provided with a sliding groove 156 distributed along the height direction, and the sliding groove 156 is at least partially located inside the water tank 10; a float 18 is slidably installed in the sliding groove 156 and can slide along the sliding groove 156 following the liquid level of the water tank 10; the first circuit board 36 includes a sensor installed on the first circuit board 36, which is set corresponding to the float 18, for detecting the position of the float 18 and determining the water level of the water tank 10 based on the position of the float 18.

[0105] In this embodiment, the first circuit board 36 is used to power the water pump 17 and transmit signals between the main control board 38 and the water pump 17. This arrangement allows for the sealed installation of the first circuit board 36. Since the first circuit board 36 is the only electrical component within the bottom assembly 1, the entire bottom assembly 1 is waterproof. Therefore, when cleaning the humidifier, the bottom assembly 1 can be washed as a whole, without having to disassemble it part by part, thus improving the ease of cleaning the humidifier.

[0106] Furthermore, the sensor can detect the position of the float 18, thereby determining the liquid level of the water tank 10. After determining the liquid level of the water tank 10, the sensor can transmit the water level signal to the main control board 38 of the upper component 2 via the first coupler 32 and the second coupler 34, so that the upper component 2 can display the water level and control the entire machine.

[0107] like Figure 15 and Figure 16 As shown, the water pump mounting bracket 15 is formed by a first bracket and a second bracket. The first bracket is mainly used to install the water pump, and it and the wet curtain bracket 11 form a sealed mounting cavity 16, which is used to install the first circuit board 36. The second bracket is provided with a sliding groove 156 to install the float 18.

[0108] In some embodiments, optionally, such as Figures 2 to 5 As shown, the bottom component 1 also includes: a water inlet pipe 14, disposed inside or outside the wet curtain 12, used to transport water to the end of the wet curtain 12 away from the water tank 10; a water inlet hole 114, disposed on the wet curtain bracket 11, and connected to the outlet of the water pump 17; a first positioning structure 122 is provided on the side of the wet curtain 12 near the water tank 10, and a second positioning structure 115 adapted to the first positioning structure 122 is provided on the wet curtain bracket 11. When the wet curtain 12 and the wet curtain bracket 11 are positioned by the first positioning structure 122 and the second positioning structure 115, the water inlet hole 114 and the inlet end of the water inlet pipe 14 are aligned and connected. When the wet curtain 12 and the wet curtain bracket 11 are positioned and installed by the first positioning structure 122 and the second positioning structure 115, it can be ensured that the water inlet hole 114 and the water inlet pipe 14 are aligned, which makes it easier to install the wet curtain 12 on the wet curtain 12 and avoids situations such as the wet curtain 12 not being installed properly.

[0109] In some embodiments, optionally, such as Figure 7 and Figure 10As shown, the first positioning structure 122 includes a first straight-side positioning structure 1222, and the second positioning structure 115 includes a second straight-side positioning structure 1152 adapted to the first straight-side positioning structure 1222. The first straight-side positioning structure 1222 and the second straight-side positioning structure 1152 can limit the installation angle of the wet curtain 12 on the wet curtain bracket 11, preventing the wet curtain 12 from shifting in the circumferential direction. More importantly, the first straight-side positioning structure 1222 and the second straight-side positioning structure 1152 can quickly and easily align the water inlet hole 114 and the water supply pipe 14, realizing foolproof installation of the wet curtain 12 and avoiding the situation where the humidifier cannot deliver water to the wet curtain 12 due to misalignment of the water inlet hole 114 and the water supply pipe 14 if the wet curtain 12 is not installed properly.

[0110] In some embodiments, such as Figure 11 and Figure 15 As shown, optionally, the humidifier further includes: a wire passage hole 152, disposed on the water pump mounting bracket 15; a wire harness, one end of which is connected to the second coupler 34, and the other end of which enters the sealed mounting cavity 16 through the wire passage hole 152 and is connected to the first circuit board 36, with the wire harness and the wire passage hole 152 in sealed contact, and / or the lowest position of the wire passage hole 152 is higher than the position corresponding to the highest design liquid level of the water tank 10; and / or a wiring cover plate 192, disposed on the wet curtain bracket 11, and forming a wire passage channel 194 with the wet curtain bracket 11, the wire passage channel 194 being used to accommodate the wire harness.

[0111] In some embodiments, the harness may optionally be a waterproof cable.

[0112] The water tank 10 serves as both a water storage container and the base of the entire machine. The water tank 10 is fixed to the air intake grille 13 by four screws at the four corners of the bottom, so that the water tank 10 and the air intake grille 13 are assembled into a water tank assembly, which allows the entire water tank assembly to be soaked in water for cleaning.

[0113] In some embodiments, optionally, such as Figures 2 to 4 As shown, the water pump mounting bracket 15 and the wet curtain bracket 11 are respectively provided with a third limiting groove and a third limiting protrusion on the two surfaces that are connected to each other, and the third limiting protrusion is located in the third limiting groove; the humidifier also includes: a first sealing member 7, which is provided between the third limiting protrusion and the third limiting groove to seal the gap between the third limiting protrusion and the third limiting groove.

[0114] In some embodiments, such as Figures 2 to 4As shown, optionally, the first sealing element 7 includes sealing silicone and / or sealing rubber, and the water pump mounting bracket 15 and the evaporative cooling pad bracket 11 are connected by threaded connectors. The connection between the water pump mounting bracket 15 and the evaporative cooling pad bracket 11 via threaded connectors is stable and reliable, ensuring the sealing performance of the mounting cavity 16. Furthermore, after the water pump mounting bracket 15 and the evaporative cooling pad bracket 11 are connected by threaded connectors, the sealing silicone, sealing rubber, and other first sealing elements 7 are pressed together to ensure a seal between them.

[0115] Optionally, such as Figure 2 As shown, the bottom of the water tank 10 is equipped with rotatable casters 102.

[0116] like Figures 1 to 4 as well as Figure 14 As shown, the humidifier includes a handle 4, which is mounted on the upper component 2. The handle 4 includes a first handle portion 42 and a second handle portion 44. The humidifier can be moved by the first handle portion 42, and the bottom component 1 and the upper component 2 can be separated by the second handle portion 44.

[0117] In this embodiment, after the bottom component 1 and the upper component 2 are assembled and locked, the entire unit can be moved via the first handle 42, thus solving the problem of how to move a humidifier with detachable top and bottom parts as a whole. During normal use, the upper component 2 and the bottom component 1 can be connected as a whole via the second handle 44, which facilitates movement of the entire unit and improves its stability, preventing the upper component 2 and the bottom component 1 from tilting due to external forces. When cleaning the humidifier is required, the upper component 2 and the bottom component 1 can be unlocked and separated via the second handle 44, allowing the upper component 2 to be disassembled for separate cleaning of the bottom component 1. When force is applied to the first handle 42, it supports the entire humidifier, facilitating movement. When an external force is applied to the second handle 44, the upper component 2 separates from the bottom component 1. At this time, the second handle 44 supports the weight of the upper component 2, allowing the upper component 2 to be moved independently via the second handle 44. This arrangement combines the first handle 42 and the second handle 44 onto the same latch 4, enabling the latch 4 to both move the entire humidifier and move the upper component 2 independently, thus separating the bottom component 1 from the upper component 2.

[0118] Optionally, the second handle 44 is movable relative to the upper component 2 between a first position and a second position. The bottom component 1 and the upper component 2 are in an assembled state. When the bottom component 1 and the upper component 2 are in the assembled state, the second handle 44 is in the first position, and the bottom component 1 and the upper component 2 are locked together. During the process of applying an external force to the second handle 44 to separate the bottom component 1 and the upper component 2, the second handle 44 is in the second position. When it is necessary to unlock the upper component 2 and the bottom component 1, an external force can be applied to the second handle 44 to move it to the second position. This allows for the unlocking of the upper component 2 and the bottom component 1 first. Then, by applying an external force, the upper component 2 can be moved, thereby achieving the separation of the upper component 2 and the bottom component 1. This design allows for both unlocking and locking of the upper component 2 and the bottom component 1 via the second handle 44, as well as separation of the upper component 2 and the bottom component 1. Furthermore, it enables a one-step unlocking and separation operation, eliminating the need for unlocking first and then separating, thereby simplifying the user's operation and improving the user experience.

[0119] Optionally, the first handle portion 42 is a handle groove 422.

[0120] In any of the above embodiments, optionally, as Figure 14 As shown, the second handle 44 includes a pressing part 442 and a locking part 444. The bottom component 1 is provided with a locking groove. When the bottom component 1 and the upper component 2 are in the assembled state, pressing the pressing part 442 can disengage the locking part 444 from the locking groove, thereby separating the upper component 2 from the bottom component 1. Releasing the pressing part 442 can cause the locking part 444 to engage with the locking groove, thereby locking the upper component 2 and the bottom component 1. The handle 4 is rotatably mounted on the upper component 2. By pressing or releasing the pressing part 442, the handle 4 can rotate relative to the upper component 2, so that the locking part 444 disengages from or engages with the locking groove. In any of the above embodiments, optionally, the humidifier further includes a spring, which is installed between the second handle part 44 and the upper component 2. The second handle part 44 can move from a first position to a second position under the action of an external force, so that the upper component 2 is separated from the bottom component 1. After the second handle part 44 is released, the spring can return the second handle part 44 from the second position to the first position, so that the upper component 2 is locked with the bottom component 1.

[0121] In some embodiments, optionally, such as Figures 2 to 4 as well as Figure 12 and Figure 13As shown, the outer casing assembly 20 includes: an outer casing panel 203; a fixed bracket 204, installed at one end of the outer casing panel 203 near the bottom assembly 1, for detachable connection with the wet curtain bracket 11; an upper cover assembly 205, installed at one end of the outer casing panel 203 away from the bottom assembly 1; a volute 25, installed between the fixed bracket 204 and the upper cover assembly 205, forming a closed electrical compartment 24 with the fixed bracket 204, the upper cover assembly 205 and the outer casing panel 203 to accommodate electrical components on the upper assembly 2; and a fan assembly 21 installed inside the volute 25, with an upper air duct 258 formed inside the volute 25, the upper air duct 258 communicating with the air inlet 132 and the air outlet 22. This design features a separate electrical compartment 24 in the upper component 2, allowing for the separation of the air duct and the electrical compartment 24. This makes it possible to add water through the air duct while preventing the air in the air duct from coming into contact with the electrical components. This provides waterproof and dustproof protection for the electrical components, thereby extending their service life.

[0122] In some embodiments, optionally, such as Figures 2 to 4 as well as Figure 13 As shown, the volute 25 includes a motor bracket 254 and an air duct enclosure 252. The air duct enclosure 252 is mounted on a fixed bracket 204, and the motor bracket 254 is mounted on the end of the air duct enclosure 252 away from the fixed bracket 204. The two are sealed together, thereby enclosing the upper air duct 258.

[0123] In some embodiments, the motor bracket 254 is optionally sealed to the upper cover assembly 205. Specifically, a sealing silicone sealant is provided between the motor bracket 254 and the upper cover assembly 205. An annular groove is provided on the motor bracket 254 to accommodate the sealing silicone sealant. The motor bracket 254 and the upper cover assembly 205 are fixed together by screws, causing the silicone sealant to deform and ensuring a seal between the upper cover assembly 205 and the motor bracket 254. This ensures that when the user adds water, water will not flow into the motor bracket 254, causing the motor 212 to malfunction.

[0124] In some embodiments, such as Figures 2 to 4As shown, optionally, the upper component 2 also includes: a main control board 38, installed inside the electrical compartment 24 and fixed on the mounting bracket 204, connected to the first coupler 32, the motor 212 of the fan assembly 21, the top water level display board 39, the top button board 37, and other sensor wiring harnesses to complete current transmission and communication. The upper component 2 also includes: a button board, installed inside the electrical compartment 24, located near the upper cover assembly 205, with physical or virtual buttons on the upper cover assembly 205. Operating the physical or virtual buttons triggers an operation signal on the button board, which is transmitted to the main control board 38 to control the humidifier's operation. The upper component 2 also includes: a display board 39, installed inside the electrical compartment 24 and connected to the main control board 38, used to display the humidifier's operating information; for example, displaying humidity and the machine's current operating mode. The display area of ​​the outer casing 203 corresponding to the display board 39 is set for visualization. The upper component 2 also includes a power socket 30, which is installed inside the electrical compartment 24 and has a power interface 302.

[0125] The following describes a humidifier in a specific embodiment.

[0126] like Figures 1 to 16 As shown, the humidifier adds water directly from the top air outlet grille, with the entire air duct serving as a water flow channel. To prevent water accumulation in the groove at the bottom of the air duct, a drainage notch is provided at the bottom of the air duct. When the user adds water, the water flows through the notch onto the wet curtain cover. Normally, the wet curtain cover is a flat surface. When the water flow is large and rapid, the flat wet curtain cover may cause water to overflow onto the outside of the wet curtain, or even flow outside the machine, resulting in water accumulation on the user's floor. Therefore, this design features an annular protrusion in the middle of the wet curtain cover. The area inside the protrusion is designed with a downward tilt angle, and the top of the protrusion abuts against the annular sponge piece attached to the back of the fixing plate.

[0127] When water flows over the top cover of the evaporative cooling pad, it flows inward along the sloping plane. If the water flow is too rapid, it may reach the height of the raised panel or submerge it. In this case, the sponge component in contact with the raised panel will further block the water from overflowing. Through these two blocking mechanisms—the raised panel and the sponge component—the problem of water overflow and excessive water flow is greatly reduced. Even if there is still some overflow, it will not have the impact force to reach the outside of the machine, thus preventing the floor from getting wet.

[0128] First, the above applies when the maximum air inlet diameter at the bottom of the duct is between the inner and outer diameters of the evaporative cooling pad assembly. When the inner diameter of the evaporative cooling pad is larger than the diameter of the duct opening, the water will fall directly into the evaporative cooling pad, and the above phenomenon will not occur.

[0129] To ensure that water flow does not pass through the external flow channel of the wet curtain cover during water addition, and to prevent water from flowing into the interior of the fixed plate through the assembly gap between the fixed plate and the air duct, thus wetting the circuit boards and other electrical components inside the fixed plate, a water-proof structure needs to be designed between the fixed plate and the air duct. The bottom of the air duct has two rings of reinforcing ribs, with the bottom of the first reinforcing rib being lower than the plane of the fixed plate, ensuring that more water is blocked inside the reinforcing rib and flows directly into the machine. The fixed plate position, which mates with the groove formed by the two flanges at the bottom of the air duct, is also designed with flanges. These flanges are higher than the top of the protrusion on the wet curtain cover, ensuring that only when the water level is higher than the protrusion can it submerge the flange of the first fixed plate and reach the innermost groove of the fixed plate.

[0130] The mounting plate and the air duct are fixed by four screws at the four corners. After the actual assembly is in place, the outer flange at the bottom of the air duct and the inner groove of the mounting plate are in surface contact support. Through the contact of the two parts, water flow into the machine is prevented. In addition, in order to ensure that the mounting plate is fully and reliably waterproof, a second rib flange is designed inside the mounting plate. This flange is high, which completely eliminates the possibility that a small amount of water seeping in from the gap between the mounting plate and the air duct can submerge the flange and reach the circuit board on the mounting plate.

[0131] The above design not only solves the problem of water flow during water addition, but also ensures the sealing of the entire air intake channel, which is also a consideration for a machine that can separate the top and bottom. The above design also solves the problem of how to achieve perfect contact and sealing between the head and bottom of the machine.
