Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and in particular to a noise-reducing drainage structure for a mist-free humidifier. Background Technology

[0002] The principle of a mist-free humidifier is to humidify the environment by blowing water from a wet curtain into the external environment through airflow. This type of mist-free humidifier uses a water pump to draw water from the tank to the top of the wet curtain for humidification. When the wet curtain or filter is saturated, excess water flows back to the bottom tank, and the pump circulates the water to the wet curtain. For example, patent number CN219415058U discloses a floor-standing mist-free humidifier with a concealed water filling structure.

[0003] Currently, when water flows back to the bottom water tank from under the humidifier's evaporative cooling pad, there is always a noticeable running and dripping sound, which bothers users and affects their experience. Therefore, further improvements are needed. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a silent water drainage structure for a mist-free humidifier.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a noise-reducing water discharge structure for a mist-free humidifier, including: a water tank, a wet curtain assembly, a wet curtain support, and a wet curtain bracket; the wet curtain bracket is mounted on the water tank, and the wet curtain support is located above the wet curtain bracket; the wet curtain assembly is installed on the wet curtain support.

[0006] The wet curtain support is provided with a drain outlet; the drain outlet allows water from the wet curtain support to fall onto the inner side of the wet curtain bracket; the wet curtain bracket is provided with several protruding intercepting parts; the intercepting parts are used to prevent water from flowing directly towards the bottom of the wet curtain bracket; an overflow gap is provided between two adjacent intercepting parts.

[0007] Optionally, the upper part of the wet curtain support is a bowl-shaped flow collection bowl, and the lower part is a columnar support cylinder; the flow collection bowl and the support cylinder are integrally formed.

[0008] Optionally, the flow interception section is located in the transition area between the flow collecting bowl and the support cylinder.

[0009] Optionally, the intercepting part is an upwardly protruding arc-shaped wall above the support cylinder.

[0010] Optionally, the flow-guiding sidewalls are provided on both sides of the flow-blocking section; the flow-guiding sidewalls of two adjacent flow-blocking sections are spaced apart to form the flow gap.

[0011] Optionally, the inner wall of the support cylinder is provided with a flow guide rib; the flow guide rib extends from the flow gap toward the bottom of the support cylinder.

[0012] Optionally, the wet curtain support is provided with an annular collection groove for collecting water overflowing from the bottom of the wet curtain assembly; the drain outlet is located below the collection groove.

[0013] Optionally, the drain outlet has an arc-shaped strip structure; the collection tank has a plurality of drain outlets evenly spaced along its circumference.

[0014] The beneficial effects of this invention are as follows: The staggered flow-intercepting sections and flow gaps on the wet curtain support form a stepped flow channel. As the water falls under gravity, it undergoes multiple flow-intercepting and buffering processes, effectively reducing the water flow velocity. Combined with the fluid shearing effect of the flow gaps, the noise of backflow is effectively reduced, eliminating auditory interference during nighttime use. The serrated flow channels formed by the flow-intercepting sections cause the water flow to be distributed in multiple curtain-like streams, preventing concentrated water flow from impacting the water tank surface and causing splashing, effectively reducing water droplet bouncing.

[0025] Example

[0026] Reference Figure 1 and Figure 2 The present invention proposes a noise-reducing drainage structure for a mist-free humidifier, comprising: a water tank 10, a wet curtain assembly 20, a wet curtain support 30, and a wet curtain bracket 40; the wet curtain bracket 40 is mounted on the water tank 10, and the wet curtain support 30 is located above the wet curtain bracket 40; the wet curtain assembly 20 is installed on the wet curtain support 30.

[0027] The wet curtain support 30 is provided with a drain outlet 31; the drain outlet 31 can allow water from the wet curtain support 30 to fall to the inside of the wet curtain bracket 40; the wet curtain bracket 40 is provided with several protruding intercepting parts 41; the intercepting parts 41 are used to prevent water from flowing directly towards the bottom of the wet curtain bracket 40; an overflow gap 42 is provided between two adjacent intercepting parts 41.

[0028] In this invention, the staggered flow-intercepting sections 41 and flow gaps 42 on the wet curtain support 40 form a stepped flow-guiding channel. During the water flow's descent under gravity, multiple flow interceptions and buffering processes effectively reduce the water flow velocity. Combined with the fluid shearing effect of the flow gaps 42, the backflow noise is effectively reduced, eliminating auditory interference during nighttime use. The serrated flow channels formed by the flow intercepting sections 41 cause the water flow to be distributed in multiple curtain-like streams, preventing concentrated water flow from impacting the liquid surface of the water tank 10 and causing splashing, effectively reducing water droplet bouncing.

[0029] In this embodiment, the upper part of the evaporative cooling pad support 40 is a bowl-shaped collecting bowl 43, and the lower part is a columnar support cylinder 44; the collecting bowl 43 and the support cylinder 44 are integrally formed. The integrated design of the collecting bowl 43 and the support cylinder 44 creates a continuous flow guiding space inside the evaporative cooling pad support 40. The bowl-shaped collecting bowl 43 can efficiently receive the water flowing vertically from the drain outlet 31, and guide the water flow to the central axis of the support cylinder 44 through the curved inner wall, avoiding turbulence noise caused by the water flow colliding with the side wall of the support.

[0030] Furthermore, the intercepting section 41 is disposed in the transition region between the collecting bowl 43 and the supporting cylinder 44. By placing the intercepting section 41 in the transition region between the collecting bowl 43 and the supporting cylinder 44, the energy dissipation characteristics of the fluid in the region of abrupt change in flow direction are fully utilized. When the water flow enters the contracting section of the supporting cylinder 44 from the bowl-shaped expansion section of the collecting bowl 43, the intercepting section 41 applies radial resistance to the water flow through its arc-shaped protrusion, forcing the water flow to form vortices in the transition region to dissipate energy.

[0031] In this embodiment, the intercepting part 41 is an upward-protruding arc-shaped wall above the support cylinder 44. When the water flows along the surface of the arc-shaped wall, the change in curvature generates centrifugal force, causing the water to flow closely to the wall surface and preventing water droplets from detaching from the wall surface and falling freely. The continuous curved surface of the arc-shaped wall can also decompose the impact force of the water flow into tangential components, reducing the vertical impact energy of the water flow on the support cylinder 44.

[0032] In this embodiment, guide sidewalls 45 are provided on both sides of the intercepting section 41; the guide sidewalls 45 of two adjacent intercepting sections 41 are spaced apart to form a flow gap 42. The combined design of the guide sidewalls 45 and the flow gap 42 achieves fine control of the flow channel. Liquid surface tension is used to suppress water droplet dispersion. This structure makes the water flow present a continuous curtain-like shape at the outlet of the flow gap 42, which can effectively reduce the amount of discrete water droplet generation compared to a design without guide sidewalls 45.

[0033] Furthermore, the inner wall of the support cylinder 44 is provided with flow guide ribs 46; the flow guide ribs 46 extend from the flow gap 42 toward the bottom of the support cylinder 44. When water flows over the surface of the flow guide ribs 46, a boundary layer is formed due to the viscosity effect, isolating the core area of ​​the water flow from the cylinder wall and reducing the shear noise between the water flow and the air. At the same time, the flow guide ribs 46 divide the inner cavity of the support cylinder 44 into multiple independent flow channels, avoiding mutual interference between water flows of different directions and thus preventing splashing.

[0034] In this embodiment, the evaporative cooling pad support 30 is provided with an annular collection groove 32 for collecting water overflowing from the bottom of the evaporative cooling pad assembly 20; the drain outlet 31 is located below the collection groove 32. The coordinated design of the annular collection groove 32 and the surrounding drain outlet 31 achieves a three-dimensional balanced distribution of water flow. The annular groove of the collection groove 32 can capture overflow water from all directions at the bottom of the evaporative cooling pad assembly 20, and the water flow is dispersed into multiple small-flow tributaries through the evenly distributed multiple drain outlets 31.

[0035] Specifically, the drain outlet 31 has an arc-shaped strip structure; the collection tank 32 has several drain outlets 31 evenly spaced along the circumference.

[0036] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
