[0002] With the increasing attention to the health of the living environment, humidifiers are widely used in places such as homes, offices, hospitals, and schools.

[0003] Among them, an evaporative humidifier uses air to blow over a water-soaked filter element. During this process, water molecules evaporate into the air along with the airflow, thereby increasing the humidity. This method is extremely natural and does not require heating or other physical changes, making the evaporative humidifier energy-saving and safe. However, during the operation of the evaporative humidifier, the water that has not been evaporated on the filter element will continue to flow back into the water tank. During this reflux process, when the water flows into the water tank, it will produce a dripping sound, resulting in noise pollution.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model

[0005] Aiming at the above-mentioned shortcomings of the prior art, the purpose of the present utility model is to provide an air humidifier to reduce the noise pollution during the operation of the humidifier.

[0006] The technical solution of the present utility model is as follows:

[0007] An air humidifier, comprising: a main body housing, on which a blower is provided; a water inlet and a water outlet are further opened at the bottom of the main body housing; a filter element, disposed within the main body housing; a water tank, disposed at the lower part of the main body housing, and the water tank is connected to the water inlet through a water pump; a sound-absorbing housing, disposed within the water tank; wherein, a diversion groove is provided on the outer side surface of the sound-absorbing housing; in the vertical direction, the upper part of the diversion groove is aligned with the water outlet; the lower part of the diversion groove extends into the liquid level of the water tank.

[0008] In a further technical solution, the width of the upper part of the diversion groove changes in a stepped manner, and the width of the groove expands to form a water-receiving groove.

[0009] In a further technical solution, the main body housing includes a bottom plate disposed at the bottom, the water inlet and the water outlet are opened on the bottom plate; on the lower surface of the bottom plate, a water guiding flange is extended around the water outlet, and the water guiding flange extends into the diversion groove.

[0010] In a further technical solution, along the length direction of the diversion groove, a water dividing rib is disposed within the diversion groove.

[0011] A further technical solution is that the diversion groove is inclined, and the included angle between the bottom surface of the diversion groove and the horizontal plane is reduced.

[0012] A further technical solution is that the upper orifice of the water inlet is higher than the orifice of the water outlet.

[0013] A further technical solution is that the water pump is arranged in the sound insulation housing, and the lower part of the sound insulation housing is open and provided with a water inlet bottom shell.

[0014] A further technical solution is that a first clamping protrusion and a first clamping groove are arranged at the opening of the sound insulation housing, and a second clamping groove is formed on the water inlet bottom shell for the first clamping protrusion to be clamped into; a second clamping protrusion is arranged on the water inlet bottom shell and extends into the first clamping groove.

[0015] A further technical solution is that a water inlet is arranged through the water inlet bottom shell, and the water inlet includes at least two small holes.

[0016] A further technical solution is that air inlet mesh holes are formed in the main body housing, and the filter element is arranged between the air inlet mesh holes and the fan.

[0017] The beneficial technical effects of the present utility model are as follows:

[0018] (1) In the air humidifier of the present utility model, a fan is arranged to blow air to flow through the filter element, evaporate water and increase humidity. This method is extremely natural and does not require heating or other physical changes. The air humidifier is both energy-saving and safe. At the same time, a water outlet is arranged at the bottom of the main body housing, and a sound insulation housing with a diversion groove is arranged to align with the water outlet. During the process of the water on the filter element flowing back to the water tank, the water always flows along the water outlet or the diversion groove. The flow velocity of the flowing water is relatively low, and the kinetic energy of the water is small, reducing the collision and disturbance between the water and the water in the water tank and reducing the generation of noise of the humidifier. A humidifier with low noise can create a more peaceful and comfortable indoor environment, and is especially suitable for use in quiet places such as offices, studies or children's rooms.

[0019] (2) Further, the width of the upper part of the diversion groove becomes wider to form a water receiving groove, and a water guiding flange is arranged at the water outlet and extends into the diversion groove, that is, the water guiding flange extends into the water receiving groove. Ensure that all the liquid flowing down along the water outlet flows into the diversion groove. And the water guiding flange extends into the water receiving groove. When the water flows into the water receiving groove along the water outlet, it flows along the water guiding flange and then falls into the contact groove, reducing the air suspension time of the water and reducing the noise generated when the water falls from the water outlet into the water receiving groove.

[0020] (3) Further, a water diversion rib is arranged in the water diversion groove, so that when water flows in the water diversion groove, it contacts the inner wall of the water diversion groove and the water diversion rib at the same time, increasing the contact area between the water and the sound-absorbing housing, further reducing the flow rate of the water, reducing the collision and disturbance between the water and the water in the water tank, and reducing the generation of noise of the humidifier.

[0032] An air humidifier includes a main body housing 1, a filter element 2, a bottom plate 3, a water tank 6, and a soundproof housing 4. A blower 11 is provided on the main body housing 1. An inlet and an outlet are also opened at the bottom of the main body housing. The filter element 2 is arranged inside the main body housing 1. The blower 11 blows air through the soaked filter element 2, enabling the water molecules on the filter element 2 to evaporate into the air with the airflow, thereby increasing the humidity. This method is extremely natural and does not require heating or other physical changes, making the air humidifier energy-saving and safe. The water tank 6 is arranged inside the water tank 6, and the water tank 6 is connected to the inlet 31 through a water pump 7. The soundproof housing 4 is arranged at the lower part of the main body housing 1. Among them, a diversion groove 42 is provided on the outer side surface of the soundproof housing 4, and the diversion groove 42 is arranged vertically. Vertically, the upper part of the diversion groove 42 is aligned with the outlet 32 to ensure that water flows smoothly along the outlet 32 onto the diversion groove 42.

[0033] Among them, the upper part of the diversion groove 42 should not be too far away from the main body housing 1 to avoid generating noise when water flows from the main body housing 1 to the diversion groove 42. The lower part of the diversion groove 42 extends into the liquid level of the water tank 6. During the process of the water on the filter element 2 flowing back to the water tank 6, the water always flows along the outlet 32 or the diversion groove 42. The flow rate of the flowing water is relatively low, and the kinetic energy of the water is small, reducing the collision and disturbance between the water and the water in the water tank 6 and reducing the generation of noise of the humidifier. A humidifier with low noise can create a more peaceful and comfortable indoor environment and is especially suitable for use in quiet places such as offices, studies, or children's rooms.

[0034] The specific structure of the diversion groove 42 is described as follows:

[0035] The groove width at the upper part of the diversion groove 42 changes step by step, and its groove width expands to form a water-receiving groove 41. The widened groove width of the water-receiving groove 41 facilitates the water at the water outlet 32 to flow into the diversion groove 42. Along the length direction of the diversion groove 42, a water-dividing rib 43 is arranged in the diversion groove 42. When the water flows in the diversion groove 42, the water-dividing rib 43 enables the water to contact the inner wall of the diversion groove 42 and the water-dividing rib 43 at the same time, increasing the contact area between the water and the sound-absorbing housing 4, further reducing the flow rate of the water, reducing the collision and disturbance between the water and the water in the water tank 6, and reducing the generation of noise of the humidifier.

[0036] In this embodiment, the diversion groove 42 is inclined, and the included angle between the bottom surface of the diversion groove 42 and the horizontal plane decreases. The diversion groove 42 can share part of the gravity of the water, further reducing the flow rate of the water in the diversion groove 42, making the water more stable, reducing the impact and turbulence generated when the water flows into the water tank 6, and reducing noise.

[0037] The specific structure of the main machine housing 1 is described as follows:

[0038] The main machine housing 1 includes a bottom plate 3 arranged at the bottom, and a water inlet 31 and a water outlet 32 are opened on the bottom plate 3. On the lower surface of the bottom plate 3, a water guiding flange 33 is arranged around the water outlet 32 and extends into the diversion groove 42. Ensure that all the liquid flowing down along the water outlet 32 flows into the diversion groove 42. And the water guiding flange 33 extends into the water-receiving groove 41. When the water flows along the water outlet 32 into the water-receiving groove 41, it flows along the water guiding flange 33 and then falls into the contact groove, reducing the air time of the water and reducing the noise generated when the water falls from the water outlet 32 into the water-receiving groove 41. An air inlet mesh hole 12 is opened on the main machine housing 1, and the filter element 2 is arranged between the air inlet mesh hole 12 and the fan 11. After the fan 11 is started, the outside air is inhaled into the main machine housing 1 along the air inlet mesh hole 12 and directly blows through the filter element 2 to evaporate the water on the filter element 2.

[0039] Furthermore, the upper orifice of the water inlet 31 is higher than the orifice of the water outlet 32. The water flowing from the filter element 2 onto the bottom plate 3 is preferentially discharged from the water outlet 32 to prevent the water from flowing back into the water pump 7 from the water inlet 31.

[0040] The specific structures of the water inlet bottom shell 5 and the sound-absorbing housing 4 are described as follows:

[0041] The water pump 7 is arranged inside the soundproof housing 4 to avoid the external placement of the water pump 7 from occupying more space. At the same time, the lower part of the soundproof housing 4 is open and provided with a water inlet bottom shell 5 to facilitate the water pump 7 to draw water from the water tank 6. At the opening of the soundproof housing 4, a first clamping protrusion 44 and a first clamping groove 51 are provided. The water inlet bottom shell 5 is provided with a second clamping groove 45 for the first clamping protrusion 44 to be inserted, and the water inlet bottom shell 5 is provided with a second clamping protrusion 52 extending into the first clamping groove 51 to fix the soundproof housing 4 and the water inlet bottom shell 5. In this way, the soundproof housing 4 and the water inlet bottom shell 5 are clamped and connected, which is convenient for disassembly and assembly and is conducive to subsequent cleaning and maintenance of the soundproof housing 4, the water pump 7 and the water inlet bottom shell 5.

[0042] Further, a water inlet 53 is provided through the water inlet bottom shell 5, and the water inlet 53 includes at least two small holes. The water inlet 53 is dispersedly arranged into a plurality of small holes to facilitate filtering impurities in the water tank 6 and avoid impurities from entering the interior of the soundproof housing 4.

[0043] The specific working process of the present utility model is as follows:

[0044] An appropriate amount of water is added to the water tank 6 in advance. When the humidifier works, the water pump 7 and the fan 11 are started. The water pump 7 draws water from the water tank 6, and the drawn water wets the filter element 2 through the water inlet 31. The fan 11 draws air outside the main body housing 1, and the drawn air blows through the filter element 2 along the air inlet mesh holes 12. In this process, the water molecules on the filter element 2 evaporate into the air along with the air, thereby increasing the air humidity. While the water molecules on the filter element 2 evaporate, part of the water that has not evaporated flows along the filter element 2 to the bottom plate 3 and then flows back into the water tank 6 along the water outlet 32, the water guiding flange 33 and the diversion groove 42.

[0045] It can be seen that in the above air humidifier, during the process of the water on the filter element 2 flowing back to the water tank 6, the water always flows along the water outlet 32 or the diversion groove 42. The flow rate of the flowing water is relatively low, and the kinetic energy of the water is small, reducing the collision and disturbance between the water and the water in the water tank 6 and reducing the generation of noise of the humidifier.

[0046] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0047] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
