The specific meaning of the above-described terms in the embodiments of the present disclosure may be understood according to the particular circumstances by those of ordinary skill in the art.
Embodiment One
[0035] In one embodiment of the present disclosure, as illustrated in
[0036] Specifically, the double-layer sound insulation and noise reduction device 100 includes a noise reduction main body 200, a water baffle 103 and a connecting member. The noise reduction main body 200 includes an annular outer wall 101 and an annular inner wall 102 located within the annular outer wall 101. The annular outer wall 101 is a plate member or a housing which is enclosed into a circle and has a ring-shaped cross section. Similarly, the annular inner wall 102 is also a plate member or a housing which is enclosed into a circle and has a ring-shaped cross section, and a cross-sectional area of the annular inner wall 102 is less than a cross-sectional area of the annular outer wall 101, so that the annular inner wall 102 may be disposed within the annular outer wall 101. In this way, a sound insulation cavity 300 is formed between the annular inner wall 102 and the annular outer wall 101 after the annular inner wall 102 is disposed to be spaced apart from the annular outer wall 101.
[0037] The annular inner wall 102 and the annular outer wall 101 are connected together through the connecting member, namely, the connecting member is connected between the annular inner wall 102 and the annular outer wall 101. In this way, the entire noise reduction main body 200 forms a unitary, non-loose component.
[0038] A distance between the annular inner wall 102 and the annular outer wall 101 is preferably in a range of 5 mm to 10 mm The sound insulation cavity 300 formed between the annular inner wall 102 and the annular outer wall 101 is in a shape of a circular three-dimensional space.
[0039] In this embodiment, a connection between the connecting member and the annular inner wall 102 or the annular outer wall 101 may be a detachable connection (such as snap-fitting, buckling and fastener locking connection), or a non-detachable connection (such as fusion, welding and integral forming). In the actual manufacturing process, a suitable connection method may be selected to connect the annular inner wall 102 to the annular outer wall 101 by the connecting member according to production conditions or based on other considerations.
[0040] Further, a side of the annular outer wall 101 is provided with an outer wall ventilation opening 105, and a side of the annular inner wall 102 is provided with an inner wall ventilation opening 107 communicating with the outer wall ventilation opening 105. The outer wall ventilation opening 105 and the inner wall ventilation opening 107 may be designed to be a groove shape or a round shape or other shapes. The number of outer wall ventilation openings 105 is more than one, and the number of the inner wall ventilation openings 107 is more than one.
[0041] Still further, a bottom of the annular inner wall 102 is formed with a water passing hole 106. In practical application, the water passing hole 106 is located below a water level of a water tank 12 in the atomizer, so that water drops generated in the atomizer flow down to a water surface along the annular inner wall 102, and thus obvious drip of water generated when water directly falls and impacts the water surface is avoided.
[0042] Preferably, the water passing hole 106 is closer to a bottom surface of the water tank 12, generally 3 mm to 5 mm Due to a fact that the water drops flow down along the annular inner wall 102 and reach the bottom of the inner wall, namely a position of the water passing opening, a distance between the water passing opening and the water surface is less than 5 mm, a drop impulse of the water drops is small, and human ears cannot hear the drip of water, thereby obviously improving the user experience. However, the water baffle 103 is disposed to cover a top of the annular inner wall 102, a position height of the water baffle 103 is set according to an actual situation of a whole machine product of an atomizer to which the water baffle 103 is applied, and a position of the water baffle 103 of the atomizer with high power may be higher.
[0043] The side of the annular inner wall 102 is further provided with a mist passing opening 104 close to or extending to the water baffle 103. That is to say, the mist passing opening 104 disposed at the side of the annular inner wall 102 may directly extend to a bottom surface of the water baffle 103 or extend to a position away from the bottom surface of the water baffle 103 by a small distance.
[0044] In this embodiment, the water baffle 103 and the noise reduction main body 200 are preferably of a same component, that is, are integrally formed, so that the overall structure is simpler, and thus the production cost is significantly reduced.
[0045] Of course, in other embodiments, the water baffle 103 and the noise reduction main body 200 may be detachably connected.
[0046] The double-layer sound insulation and noise reduction device 100 provided by the embodiments of the present disclosure is suitable for use in the atomizer, when the atomizer is working, a ultrasonic atomization sheet 11 of the atomizer vibrates at a high frequency to cause water to vibrate upward and thus pass through the water passing hole 106, and after reaching a certain height, formed water drops are blasted into particles and mist. A fan 13 of the atomizer conveys power air through the outer wall ventilation opening 105 and the inner wall ventilation opening 107 to blow out the mist from the mist passing opening 104 above. Since the sound insulation cavity 300 is formed between the annular inner wall 102 and the annular outer wall 101 of the noise reduction main body 200, when the water drops flow down along an inner surface of the annular inner wall 102, the drip of water appears on the water surface, and sound waves of the water drops pass through the annular inner wall 102, are scattered within the sound insulation cavity 300, and spread in all directions. Therefore, the sound wave energy is obviously consumed inside and around the sound insulation cavity, so that the sound wave penetration loss amount is significantly increased, and a good mute effect is achieved.
[0047] The penetration loss amount refers to a difference between incident sound energy and emergent sound energy, and is an important parameter for reflecting a sound insulation effect. The larger the sound wave penetration loss amount is, the better the sound insulation effect is. In this way, the drip of water generated by the atomizer with this double-layer sound insulation and noise reduction device 100 is significantly isolated and consumed, and then the noise transmitted to and heard by the human ear is very small.
[0048] In this embodiment, as illustrated in
[0049] The application of the double-layer sound insulation and noise reduction device 100 provided by this embodiment to the atomizer will be further described as an example.
[0050] As illustrated in
[0051] As illustrated by arrow direction routes of R1, R2 and R3, the fan 13 works to blow out the power air from the air outlet 14, the power air reaches an inner cavity air inlet 15 along an air duct, and the air blows small atomized particles out of the mist passing opening 104 through the outer wall ventilation opening 105 and the inner wall ventilation opening 107. Under an action of air force, the mist keeps going upwards to pass through the mist outlet channel 17 and reaches a position above a point C outside the mist outlet 16, thereby forming a mist spray form in which the mist is scattered upwards is formed.
[0052] Further, in the double-layer sound insulation and noise reduction device 100, after the vibrated water drops are blasted at the point B, the water drops are blasted into particles and mist. As described above, the mist is blown away from the point C, while the large particles are dispersed into the water baffle 103 and flow down along the annular inner wall 102 to a point D in a horizontal plane WL to produce the drip of water, where the point D is a source of noise generation where the drip of water occurs. The noise diffuses and propagates at the point D, and part of the noise penetrates into water downwards so that the energy is absorbed. Most of the noise propagates sideways and upwards through the annular inner wall 102 to an interlayer cavity, for example to points E1, E2, E3, E4 illustrated in
