Embodiment 1

[0032] A sound-absorbing air filter unit such as Figure 1-Figure 2 As shown, it includes an air inlet pipe 1, a toilet flush tank 2, an air outlet pipe 3 and a silencer 4. The air inlet pipe 1 is provided with a blower 5 that sucks outdoor air into the toilet flush water tank 2, and the air inlet of the air inlet pipe 1 communicates with the outside. , the outdoor air is continuously sucked into the air intake pipe 1 by the blower 5, and delivered to the toilet flush tank 2, the air outlet of the air intake pipe 1 stretches into the water in the toilet flush water tank 2, and the air inlet 31 of the air outlet pipe 3 is set In the toilet flush tank 2 and above the water surface, the air inlet 31 of the air outlet pipe 3 is in the shape of an inverted bowl, which increases the contact area with the purified air, which is beneficial to the discharge of the purified air. Connected with the room, the noise reduction device 4 is fixedly arranged in the toilet flush tank 2; the noi...

Embodiment 2

[0038] The fixed plate 41 of a kind of sound-absorbing air filtering device of the present invention can be replaced by hollow double-layer plate, as Figure 3-Figure 4 As shown, the fixed plate 41 is perforated with a through hole 411 in the vertical direction, and the through hole 411 is isolated from the space in the fixed plate 41. The side of the fixed plate 41 is provided with a vent 412, and the air outlet of the air inlet pipe 1 is connected to the air outlet. The air vent 412 communicates, and the bottom of the conical protrusion 42 communicates with the space inside the fixing plate 41 .

[0039] After adopting the above-mentioned structure, the present invention provides a sound-absorbing air filter device. The water in the toilet flushing tank 2 will diffuse to the conical protrusion 42 through the through hole 411, but will not flow into the fixed plate 41. The outdoor air is absorbed into the inner space of the fixed plate 41, the outdoor air escapes through the ...

Abstract

The invention discloses a silenced air filtering device which comprises an air inlet pipe, a purified water tank, an air outlet pipe and a silencing device, wherein an air blower for inhaling outdoor air into the purified water tank is arranged on the air inlet pipe; the air inlet of the air inlet pipe is communicated with the outdoor space; the air outlet of the air inlet pipe stretches into water in the purified water tank; the air inlet of the air outlet pipe is formed in the purified water tank and is positioned on the water surface; the air outlet of the air outlet pipe is connected with the indoor space; the silencing device is arranged in the purified water tank and comprises a fixing plate; the purified water tank is separated into two cavities by virtue of the fixing plate; the lower surface of the fixing plate is contacted with water; multiple hollow conical protrusions are formed on the fixing plate; openings are formed in positions, which correspond to the conical protrusions, at the bottom of the fixing plate; and multiple holes are formed in the conical protrusions. According to the silenced air filtering device disclosed by the invention, the indoor air quality can be improved, the operating noise is effectively reduced, and a quiet environment is provided for people.

Description

technical field [0001] The invention relates to the field of filter devices, in particular to a sound-absorbing air filter device. Background technique [0002] With the increasing environmental pollution, the dust pollution and smog in some cities are becoming more and more serious. Dust and smog enter the room with the air, which has a certain impact on people indoors and easily induces the onset of respiratory diseases and Allergic symptoms caused by house dust. Therefore, in order to improve the indoor air environment, an air cleaner or an air conditioner with an air cleaning function is usually used indoors. As a method of purifying indoor air, generally speaking, a blower is used to suck pollutants into an air purifier, and the pollutants are removed by a filter device. For example, the authorized announcement number is CN 203916368U, and the invention patent named "a new type of air filter device" discloses an air filter device, including an air intake pipe, a purif...
