Detailed Description

For a better understanding of the objects, structure and function of the utility model, an atomizing assembly and a humidifier of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 2, the atomizing assembly of the present invention includes a sleeve 1. Sleeve 1 sets up in the water tank, and 1 lower extreme of sleeve is installed on the water tank diapire, makes and soaks in the sleeve 1 lower extreme in the surface of water. The water tank still is equipped with atomizing piece 2, forms atomizing chamber 11 in the sleeve 1. The atomizing plate 2 is located the downside of atomizing chamber 11 extending direction to atomizing plate 2 can arouse a water column 6 on the surface of water through ultrasonic oscillation and go deep into atomizing chamber 11, and water column 6 disperses to the drop of water and the production that accompanies the fog at water column 6 upper end. And a top cover 5 is installed on the top surface of the water tank, a mist outlet 51 is formed in the top cover 5, and mist passes through the upper end of the atomizing chamber 11 and is discharged to the outside from the mist outlet 51 so as to adjust the humidity of the external environment. Wherein, sleeve 1 can pass through modes fixed connection such as buckle with the water tank, also can integrated into one piece. The water in this embodiment is generally pure water, but may be an aqueous solution or other liquid that flows like water on the premise of meeting safety standards.

If the water level in the water tank is too high, the atomizing plate 2 at the bottom will have difficulty in generating a water column 6 above the water level. Therefore, the atomizing cavity 11 is sleeved with the energy gathering ring 3, and the density of the energy gathering ring 3 is slightly smaller than that of water, so that the energy gathering ring 3 floats on the liquid level, most of the energy gathering ring 3 is immersed in the liquid level to be small, and only a small part of the energy gathering ring 3 leaks out of the liquid level. Along with the change of the water surface height in the water tank, the height of the energy gathering ring 3 changes. The through holes 31 of the energy-gathering ring 3 collect the ultrasonic waves generated by the atomizing plate 2, namely the ultrasonic waves generated by the atomizing plate 2 are reflected in the through holes 31 of the energy-gathering ring 3 to accumulate energy, so that the water column 6 is excited by the water surface in the atomizing cavity, and the purpose of high-water-level water outlet is achieved.

When the power of the atomizing plate 2 is high, the water column 6 can strike the top cover 5 of the humidifier to generate water splashing noise; when the power of the ultrasonic atomization sheet 2 is small, water drops of the water column 6 fall to generate water drop noise on the inner wall of the sleeve 1 easily, and poor user experience is caused. The noise generated as described above is intensified by the arrangement of the energy collecting ring 3.

In order to reduce the noise, the upper end of the atomizing cavity 11 is provided with a baffle 4; the baffle 4 is provided with a guide inclined plane 41, the guide inclined plane 41 is obliquely arranged relative to the atomizing cavity 11, and a mist passing opening 12 is formed between one side of the baffle 4 and the inner wall of the atomizing cavity 11. So that the atomizing plate 2 generates the water column 6 to impact the guide slope 41. A drainage included angle is formed between the guide inclined plane 41 and the inner wall of the atomization cavity 11, and the guide inclined plane 41 leads the water column 6 to the inner wall of the atomization cavity 11 through the drainage included angle, so that the water column 6 flows back along the inner wall of the atomization cavity 11. Wherein, the included angle of drainage is set according to the model of the product, generally between 30 degrees and 60 degrees.

As the flap 4 is in front of the top cover 5, the water column 6 no longer hits the top cover 5. Moreover, because the guide slope 41 is arranged obliquely relative to the water column 6 and only bears a part of the impact force of the water column 6, the sound of the water column 6 impacting the baffle 4 is much smaller than the sound of the water column 6 impacting the top cover 5. Secondly, the water column 6 moves along the guiding inclined plane 41, is guided to the side wall of the atomizing cavity 11, and then flows back to the water tank along the side wall of the atomizing cavity 11. In conclusion, through the setting of separation blade 4, two main sources of noise have been reduced to reach the requirement of the noiseless work of atomizing subassembly low noise, promote user experience. Moreover, due to the baffle plate 4, large water drops can not pass through the mist outlet 51, and no water drops are accumulated on the surface of the top cover 5 close to the mist outlet 51.

Since the guide slope 41 is obliquely disposed, the shutter 4 is provided with a first side end 42 and a second side end 43. The first side end 42 is located on the side of the guide slope 41 away from the atomizing plate 2, i.e., the higher side of the baffle 4. The second side end 43 is located on the side of the guide slope 41 close to the atomizing plate 2, i.e., the lower side of the shutter 4.

Generally, the mist passing port 12 is located between the first side end 42 and the inner wall of the atomizing chamber 11. Correspondingly, the flap 4 is provided at the second side end 43 with a connecting structure for fixing the flap 4 to the inner wall of the nebulization chamber 11. This is because the water column 6 and the mist advance from the side close to the atomizing plate 2 to the side far from the atomizing plate 2 from the bottom to the top, and the mist passing opening 12 is located at the side of the first side end 42 and is adapted to the advancing tendency of the mist. On the other hand, if the mist passing port 12 is provided on the side of the second side end 43 and the connection structure is provided on the second side end 43, a part of the mist is blocked by the connection structure and is difficult to be discharged from the mist passing port 12. Of course, the mist passing opening 12 is disposed at one side of the second side end 43, which also has the effect of facilitating the disposition and reducing the water column 6 and the overflow of water droplets.

Referring to fig. 3, an air inlet 13 is formed in the inner wall of the atomizing chamber 11, and the air inlet 13 is communicated with the mist passing opening 12, so that air enters the mist passing opening 12 from the air inlet 13 by the rotation of the fan. For whole fog chamber upper end be fog outlet 51 when not setting up separation blade 4, the fog outlet 51 that is located between separation blade 4 and the fog intracavity wall is obviously littleer, and littleer flow area can effectively improve wind speed and wind pressure under the certain prerequisite of the fan production amount of wind, and fog obtains bigger pressure at air intake 13 and sends into and flee behind fog outlet 51.

And to ensure a consistent flow pattern, the air inlet 13 is generally disposed opposite the first side end 42. Of course, if the mist outlet 51 is disposed at one side of the second side end 43, the air inlet 13 is located at one side of the second side end 43 far from the first side end 42 to reduce wind resistance. According to the requirement, the first side end 42 and the air inlet 13 can be arranged in a relatively staggered manner, that is, a height difference exists between the first side end 42 and the air inlet 13 in the axial direction of the sleeve 1, so that the flow guiding inclined plane is prevented from flowing into the air inlet 13.

The connecting structure can be in different structures according to the requirements of the situation. As shown in fig. 4, the connection comprises a convex edge 44 disposed on the inner wall of the atomizing chamber 11, the end of the convex edge 44 forms a connecting portion 45, and the second side end 43 of the baffle 4 is fixed at the end of the connecting portion 45. In order to save space of the sleeve 1, the flange 44 is located at the upper end edge of the atomizing chamber 11, and the connecting portion 45 extends axially along the sleeve 1 from top to bottom. In addition to the above structure, the second side end 43 of the baffle 4 may be directly formed integrally with the inner wall of the atomizing chamber 11, but the volume of the tank body surrounded by the upper side of the baffle 4 is increased, and water is easily stored. Besides the baffle 4 is integrally formed, a common connecting structure such as a thermoplastic structure and a buckle structure can also be adopted.

In order to prevent water from accumulating on the upper side of the baffle 4, a drainage slope may be formed on the upper side of the baffle 4 so that the baffle 4 is wedge-shaped.

The utility model also discloses a humidifier which comprises the atomization assembly and the fan. Mist is generated by the atomizing assembly to adjust humidity. Furthermore, even if the atomizing assembly is not provided with the energy concentrating ring 3, a baffle 4 may be provided on the sleeve 1 to further eliminate noise.

The atomization assembly can be applied to devices such as a central air conditioner and an oven and the like which need to adjust humidity besides the humidifier.
