This design can prevent backflow water from dripping directly onto the water surface of the water tank and thus avoid generating water noise, providing an excellent quiet experience.

[0005] This utility model provides a humidifier, comprising: A water tank, having a accommodating space and an opening communicating with the accommodating space; A water collection tray, covering the opening, is provided with a drain outlet. A water-repellent cover is installed on the water receiving tray and located above the drain outlet; A flow guide shroud is disposed within the accommodating space. The flow guide shroud has a first flow guide surface and a second flow guide surface connected to each other. The first flow guide surface is disposed opposite to the drain outlet, and the first flow guide surface is provided with a hemispherical water receiving platform. The second flow guide surface is disposed inclined downward relative to the first flow guide surface. The flow guide shroud is provided with a water outlet at the lower end position corresponding to the second flow guide surface.

[0006] According to the present invention, a humidifier is provided with a water-blocking component on the second guide surface. The water-blocking component is configured to form a liquid flow channel on the second guide surface to guide the liquid flowing through the water receiving platform to flow step by step in the liquid flow channel and to be discharged into the accommodating space through the water outlet.

[0007] According to the humidifier provided by this utility model, the water-blocking component includes: Multiple water-blocking strips are provided, and the liquid flow channel formed by the multiple water-blocking strips is S-shaped.

[0008] According to the present invention, a humidifier is provided with an annular water dam on the side of the drain outlet opposite to the water receiving platform, and the projection of the annular water dam on the first guide surface surrounds the water receiving platform.

[0009] According to the present invention, a humidifier further includes: The pump body has an installation space adapted to the pump body, and at least part of the pump body is disposed in the installation space. Liquid flowing through the second guide surface flows on the top surface of the pump body and is discharged to the accommodating space through the outlet.

[0010] According to the present invention, a humidifier is provided, wherein the pump body has a water inlet that is connected to the accommodating space, and the water outlet is located on the side of the guide shroud facing away from the water inlet.

[0011] According to the present invention, a humidifier has a third guide surface, and at least part of the water outlet is disposed on the third guide surface; wherein, along the height direction of the humidifier, the height of the third guide surface is less than or equal to the height of the top surface of the pump body.

[0012] According to the present invention, a humidifier is provided, wherein the water receiving tray includes an installation part, a connecting part, and a drain part, the drain part being connected to the installation part through the connecting part, wherein the height of the drain part is less than the height of the installation part along the height direction of the humidifier, and the drain outlet is disposed on the drain part.

[0013] According to the present invention, a humidifier is provided, wherein the water outlet has a recessed portion and the water outlet is disposed in the recessed portion; wherein the hydrophobic cover includes a cover body and a plurality of connecting members, the cover body is connected to the recessed portion through the plurality of connecting members, the cover body is located above the water outlet, and the plurality of connecting members are arranged sequentially at intervals along the circumferential direction of the water outlet.

[0014] According to the humidifier provided by this utility model, the water receiving tray is further provided with a water outlet, and the water receiving tray is provided with a water-blocking ring at the edge of the water outlet; wherein, along the height direction of the humidifier, the height of the top surface of the water-blocking ring is greater than the height of the water outlet.

[0015] The humidifier provided by this utility model has a water-draining cover installed at the drain outlet of the water receiving tray. This cover disperses the large flow of water into multiple fine streams before it flows into the drain outlet, thereby reducing the overall impact force of the water flow. A guide cover is located inside the water tank to receive the return water from the water receiving tray. The first guide surface of the guide cover is located below the drain outlet of the water receiving tray, and a water-receiving platform is provided on the first guide surface. This shortens the drop height of the return water from the drain outlet to the first guide surface, reducing the impact energy at the source. Furthermore, the fine streams of water flowing from the drain outlet are evenly spread outwards upon contact with the surface of the water-receiving platform, thus avoiding the impact noise caused by the water clumps falling. The water dispersed by the water-receiving platform flows down the slope formed by the second guide surface and finally flows into the water tank through the outlet on the guide cover. Thus, through the multi-stage progressive noise reduction design consisting of a water-dispersing cover to disperse the water flow, a water-receiving platform to buffer and disperse the water flow, and a slope to guide the water flow, the backflow water can be prevented from dripping directly onto the water surface of the tank and thus generating drainage noise, providing an excellent quiet experience.

[0031] like Figure 1 and Figure 2 As shown, the humidifier of this utility model embodiment includes: a water tank 1, a water receiving tray 2, a drainage cover 3, and a flow guide 4. The water tank 1 is provided with a receiving space 11 and an opening communicating with the receiving space 11; the water receiving tray 2 covers the opening and is provided with a drain outlet 2311; the drainage cover 3 is provided on the water receiving tray 2 and located above the drain outlet 2311; the flow guide 4 is provided in the receiving space 11 and has a first flow guide surface 41 and a second flow guide surface 42 connected to each other. The first flow guide surface 41 is arranged opposite to the drain outlet 2311, and the first flow guide surface 41 is provided with a water receiving platform 411. The second flow guide surface 42 is inclined downward relative to the first flow guide surface 41; wherein, the flow guide 4 is provided with a water outlet 431 at the lower end position corresponding to the second flow guide surface 42.

[0032] Specifically, the water tank 1 serves as the main water storage unit of the humidifier, and the water receiving tray 2 is located at the opening of the water tank 1 to receive the injected water or collect the return water. The drain cover 3 is installed at the drain outlet 2311 of the water receiving tray 2, which can disperse the large flow of water into multiple fine streams before the return water flows into the drain outlet 2311, thereby reducing the overall impact force of the water flow.

[0033] It should be noted that the flow guide 4 is located inside the water tank 1 and can receive the return water from the water receiving tray 2. The flow guide 4 is a hollow structural component, and it can also be a one-piece structure. The first flow guide surface 41 of the flow guide 4 is located below the drain outlet 2311 of the water receiving tray 2, for example, directly below the drain outlet 2311. The first flow guide surface 41 can be a horizontal plane, opposite to the drain outlet 2311 and spaced apart. A water receiving platform 411 is provided on the first flow guide surface 41. On the one hand, it can shorten the falling height of the return water from the drain outlet 2311 to the first flow guide surface 41, reducing the impact energy from the source; on the other hand, after the fine water flowing down from the drain outlet 2311 comes into contact with the surface of the water receiving platform 411, it will be evenly spread out in all directions, thereby avoiding the impact noise caused by the water flowing down in clumps.

[0034] Understandably, the second guide surface 42 of the flow guide shroud 4 is connected to the first guide surface 41 and is set at an angle. The water dispersed by the water receiving platform 411 will flow along the slope formed by the second guide surface 42 and finally flow into the water tank 1 through the outlet 431 on the flow guide shroud 4. The inclination angle of the second guide surface 42 can be set to 60°, 45° or 30°, etc.

[0035] In this embodiment, the multi-stage progressive noise reduction design, consisting of a hydrophobic cover 3 to disperse the water flow, a water receiving platform 411 to buffer and disperse the water flow, and a slope to guide the water flow, can prevent backflow water from dripping directly onto the water surface of the water tank 1 and thus generating water discharge noise, thereby providing an excellent quiet experience.

[0036] In optional embodiments, such as Figure 3 and Figure 4 As shown, the second guide surface 42 is provided with a water-blocking component 421. The water-blocking component 421 is configured to form a liquid flow channel on the second guide surface 42 to guide the liquid flowing through the water receiving platform 411 to flow step by step in the liquid flow channel and be discharged to the receiving space 11 through the outlet 431.

[0037] For example, a water-blocking component 421 is integrally formed on the second guide surface 42. The water-blocking component 421 can be a water-blocking strip 4211 of a specific shape or a guide rib. The water-blocking component 421 constructs a non-linear preset liquid flow channel on the second guide surface 42. That is to say, the liquid flow channel is a structure that allows water to flow in stages.

[0038] Understandably, the water-blocking component 421 can form a series of steps, allowing water spreading from the receiving platform 411 to first flow into the first-level shallow pool, fill up, and then overflow into the next-level shallow pool, repeating this process step by step downwards. This maximizes the absorption of water kinetic energy and transforms the flow state into a gentle overflow. Alternatively, a meandering flow channel design can be adopted, with the water-blocking component 421 forming a curved S-shaped or zigzag narrow waterway, forcing the water flow to extend its path and duration, effectively reducing the flow velocity and ensuring that the water flow is stable and slow when it reaches the outlet 431.

[0039] To achieve silent water inlet for return flow, in practical applications, the water-blocking assembly 421 includes multiple water-blocking strips 4211, and the liquid flow channel formed by the multiple water-blocking strips 4211 is S-shaped. For example, the water-blocking assembly 421 includes two water-blocking strips 4211, and an S-shaped liquid flow channel is formed between the two water-blocking strips 4211.

[0040] In practical applications, the water receiving platform 411 is a hemispherical protrusion. In this way, the small stream of water falling from the drain outlet 2311 directly contacts this smooth convex curved surface, and the energy is effectively buffered. At the same time, the water flow will spread evenly in all directions along the spherical surface, avoiding the noise generated by water droplets directly impacting the first guide surface 41.

[0041] In optional embodiments, such as Figure 2 As shown, an annular dam 2312 is provided on the side of the drain outlet 2311 opposite to the water receiving platform 411. The projection of the annular dam 2312 onto the first guide surface 41 surrounds the water receiving platform 411. In this way, the water discharged from the drain outlet 2311 is collected within the projection area of ​​the annular dam 2312 and falls onto the water receiving platform 411, so that the water discharged downward from the drain outlet 2311 is dispersed as much as possible by the water receiving platform 411.

[0042] In optional embodiments, such as Figure 5 and Figure 6 As shown, the humidifier in this embodiment also includes a pump body 5. The flow guide shroud 4 is provided with an installation space 44 adapted to the pump body 5. At least part of the pump body 5 is disposed in the installation space 44. The liquid flowing through the second flow guide surface 42 flows on the top surface of the pump body 5 and is discharged to the accommodating space 11 through the outlet 431.

[0043] It should be noted that the guide shield 4 has an installation space 44 that matches the shape of the pump body 5, allowing at least a portion of the pump body 5 to be embedded into the installation space 44 to complete the assembly of the pump body 5 and the guide shield 4. At this time, the water flowing through the second guide surface 42 will first flow along the top surface of the pump body 5, and finally be discharged from the outlet 431 of the guide shield 4 into the accommodating space 11 of the water tank 1.

[0044] To prevent air carried by the return water from being sucked into the pump body 5, and to prevent air intake from affecting the normal operation of the pump body 5, in an optional embodiment, such as... Figure 6 As shown, the pump body 5 has a water inlet 51, which is connected to the accommodating space 11. The water outlet 431 is located on the side of the guide shroud 4 away from the water inlet 51.

[0045] In optional embodiments, such as Figure 7 As shown, the flow guide shroud 4 has a third flow guide surface 43, and at least part of the water outlet 431 is disposed on the third flow guide surface 43; wherein, along the height direction of the humidifier, the height of the third flow guide surface 43 is less than or equal to the height of the top surface of the pump body 5.

[0046] It should be noted that the third guide surface 43 can be a horizontal surface, with its height being about 10mm lower than the top surface of the pump body 5. In this way, the water flowing through the second guide surface 42 first flows along the top surface of the pump body 5, then flows to the third guide surface 43, and finally flows from the outlet 431 on the third guide surface 43 into the containing space 11 of the water tank 1.

[0047] It is particularly important to note that, along the height direction of the humidifier, the first guide surface 41 is positioned above the second guide surface 42, the second guide surface 42 is positioned above the top surface of the pump body 5, and the top surface of the pump body 5 is positioned above the third guide surface 43. Furthermore, along the first direction, the first guide surface 41, the second guide surface 42, the top surface of the pump body 5, and the third guide surface 43 are arranged sequentially. The first direction is perpendicular to the height direction.

[0048] In optional embodiments, such as Figure 8 As shown, the water tray 2 includes an installation part 21, a connecting part 22, and a drain part 23. The drain part 23 is connected to the installation part 21 through the connecting part 22. The height of the drain part 23 is less than the height of the installation part 21 along the height direction of the humidifier. The drain outlet 2311 is provided on the drain part 23.

[0049] It should be noted that the mounting part 21, as the outer edge of the water receiving tray 2, can be securely installed on the opening of the water tank 1; the drain part 23 is located in the center or designated area of ​​the water receiving tray 2 and is the lowest point of the water receiving tray 2; while the connecting part 22 serves as a transition area and is used to connect the mounting part 21 and the drain part 23.

[0050] Understandably, the height of the drain section 23 is lower than the height of the mounting section 21 along the height direction of the humidifier. In this way, the return water can automatically and quickly collect at the location of the drain outlet 2311 under the action of gravity, which can avoid water accumulation on the water tray 2.

[0051] In optional embodiments, such as Figure 2 and Figure 8 As shown, the drain section 23 has a recessed portion 231, and the drain outlet 2311 is disposed in the recessed portion 231. The drainage cover 3 includes a cover body 31 and multiple connectors 32. The cover body 31 is connected to the recessed portion 231 via the multiple connectors 32. The cover body 31 is located above the drain outlet 2311, and the multiple connectors 32 are sequentially spaced along the circumferential direction of the drain outlet 2311. An annular dam 2312 is located on the side of the recessed portion 231 opposite to the water-receiving platform 411. The annular dam 2312 is located on the outer periphery of the drain outlet 2311; exemplarily, the annular dam 2312 is disposed around the edge of the drain outlet 2311.

[0052] It should be noted that the connector 32 can be a sheet-like structural component, and the cover 31 includes a connected top wall and side walls, with the top wall having an arc-shaped surface. The cover 31 is suspended above the drain outlet 2311 via the connector 32. Water flowing into the recess is blocked by the cover 31 and cannot flow directly out of the drain outlet 2311; it can only pass through the gaps between the multiple connectors 32. In this way, the complete water flow can be divided into multiple small, independent streams.

[0053] In optional embodiments, such as Figure 8 As shown, the water receiving tray 2 is also provided with a water outlet 232, and a water baffle ring 233 is provided on the edge of the water outlet 232; wherein, along the height direction of the humidifier, the height of the top surface of the water baffle ring 233 is greater than the height of the drain outlet 2311.

[0054] It should be noted that a drain outlet 232 is provided in the lower part 23 of the water receiving tray 2, allowing the water injected during filling to flow quickly and smoothly directly into the water tank 1. Simultaneously, a water-retaining ring 233 is added around the drain outlet 232 to prevent backflow water from flowing directly from the drain outlet 232 into the water tank 1, thereby reducing drainage noise generated along this path. In this embodiment, there can be multiple drain outlets 232, arranged around the recessed portion 231.

[0055] Finally, it should be noted that the terms "parallel" and "perpendicular" in the embodiments of this utility model should not be strictly limited to a geometric sense. At least manufacturing and installation errors should be considered. For example, an error of ±10° should be within the protection range of the embodiments of this utility model. The above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
