[0002] With the continuous changes in environmental pollution and the increasing health awareness of people, air purifiers have become essential appliances in many homes and offices. Especially for families with elderly people, children, pregnant women, and other sensitive groups, air purifiers can effectively remove harmful substances from the air, creating a healthy breathing environment. However, noisy air purifiers, especially those lacking noise reduction design, can negatively impact sleep quality. Continuous noise can lead to insomnia and frequent awakenings, affecting daytime work and study efficiency. Long-term noise exposure may cause a deterioration in mental state, negatively impacting physical and mental health. Severe noise can also increase the risk of cardiovascular disease.

[0003] Currently, most commercially available air purifiers offer good air purification performance, but improvements in noise reduction and sound absorption are minimal. Some purifiers experience increased noise levels and filter buildup with prolonged use, and are difficult to disassemble and clean in daily life. Some purifiers also use multiple high-speed fans to improve airflow efficiency, which further increases noise levels. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 As shown, this utility model discloses a silent air purifier, including a rectangular housing 1 with supporting feet 8 at the bottom. Two air inlets 2 are located on the side walls of the housing 1, on the left and right sides respectively. An air outlet 3 is located at the top of the housing 1. The purifier also includes a first filter plate 4 and a second filter plate 6. The first filter plate 4 is disposed inside the housing 1 and above the air inlets 2, while the second filter plate 6 is fixedly connected to the inner wall of the housing 1 and above the first filter plate 4. Furthermore, it includes a hemispherical sound-absorbing component 72, an inner wall sound-absorbing component 71, and a fan assembly 5. The fan assembly 5 is disposed between the first filter plate 4 and the second filter plate 6, and the blades 51 of the fan assembly 5 have a radius of not less than 8 cm. Preferably, in this embodiment, the blades 51 of the fan assembly 5 have a radius of 10 cm. Using a fan assembly with larger blades ensures that the airflow speed is not affected while reducing the fan speed, thereby effectively reducing the fan's noise. The hemispherical sound-absorbing component 72 is fixedly disposed in the center of the top wall of the housing 1, and the inner wall sound-absorbing component 71 is fixedly disposed on the inner wall of the housing 1 above the second filter plate 6. The hemispherical sound-absorbing component 72 can change the flow path of the purified air to slow down the flow rate of the purified air and reduce the noise generated by the highly flowing air. The sound-absorbing materials of the hemispherical sound-absorbing component 72 and the inner wall sound-absorbing component 71 can effectively absorb noise and further reduce noise. In this embodiment, the sound-absorbing component material can be any one of glass fiber, sound-absorbing cotton, polyester fiber sound-absorbing board, or other sound-absorbing board, as long as it has a good sound absorption effect.

[0021] like Figures 1-2 As shown, in this embodiment, the first filter plate 4 mainly filters relatively large particulate harmful substances. Therefore, dust inevitably accumulates on the first filter plate 4 with long-term use, making it difficult for air to pass through and thus increasing noise. During daily use and maintenance, noise generation can be reduced by cleaning the removable filter plate. The housing 1 is provided with an upper sliding groove 13 and a lower sliding groove 15. The upper sliding groove 13 is located above the first filter plate 4, and the lower sliding groove 15 is located below the first filter plate 4. The distance between the upper sliding groove 13 and the lower sliding groove 15 is wider than the thickness of the first filter plate 4. The first filter plate 4 is detachably disposed between the upper sliding groove 13 and the lower sliding groove 15. The lower surface of the upper sliding groove 13 and the upper surface of the lower sliding groove 15 are respectively provided with a recess 14. The upper surface and lower surface of the first filter plate 4 are each provided with a protrusion 41 that matches the recess 14, ensuring that the first filter plate 4 can be securely inserted into the upper sliding groove 13 and the lower sliding groove 15 through the protrusion 41. The first filter plate 4 has a handle 42 at one end, which is fixedly connected to the side of the first filter plate 4. Both the upper and lower surfaces of the handle 42 have grooves 43. After use, the first filter plate 4 can be pulled out along the handle 42 to rinse off the dust. After rinsing and drying, the first filter plate 4 is inserted back into the housing 1 along the upper slide groove 13 and the lower slide groove 15 until the protrusion of the first filter plate 4 is engaged in the recess 14. Rinsing off the dust on the first filter plate 4 eliminates the noise caused by dust accumulation making it difficult for air to pass through the first filter plate 4.

[0022] like Figure 1 As shown, in this embodiment, the second filter plate 6 is curved. The curved shape of the filter plate increases the contact area with air, achieving a better air filtration effect. The bottom of the support foot 8 is provided with an anti-slip and shock-absorbing pad 81, which is fixedly connected to the support foot 8. The anti-slip and shock-absorbing pad 81 not only increases the friction between the support foot and the ground during daily use but also reduces the noise caused by the shaking of the air purifier during operation.

[0023] like Figures 1-2As shown, in this embodiment, two fixing blocks 11 are provided on the left and right sides of the housing 1. The fixing blocks 11 are fixedly connected to the inner wall of the housing 1. The fan assembly 5 is disposed between the four fixing blocks 11. A rubber damping layer 12 is provided between the fan assembly 5 and the fixing blocks 11, and the rubber damping layer 12 is fixedly connected to the fan assembly 5. The rubber damping layer 12 provided between the fan assembly 5 and the fixing blocks 11 can reduce the contact vibration between the fan assembly 5 and the fixing blocks 11 when the fan is working by utilizing the buffering elasticity of the rubber damping layer 12, thereby reducing the noise impact caused by the vibration.

[0024] This invention reduces fan noise by using larger fan blades to ensure airflow and speed while reducing fan speed. It also reduces noise by using a hemispherical sound-absorbing component to divert purified air, slowing the airflow and further reducing noise. Furthermore, the inherent properties of the materials used in the hemispherical and inner wall sound-absorbing components eliminate excess noise, further reducing noise levels within the purifier. This invention improves air purifier noise levels from multiple angles, effectively reducing noise pollution without compromising purification performance, thus creating a healthy breathing environment.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
