[0002] As living standards continue to improve, more and more people are paying more attention to their quality of life. People not only need clean and beautiful living and working spaces, but also clean, odor-free air. To improve the air environment, people often use methods such as spraying perfumes or essential oils in rooms to improve air quality, thereby keeping the air fresh, eliminating odors, and disinfecting. However, spraying perfumes or essential oils in a room is relatively troublesome, requiring frequent spraying to maintain the fragrance. Furthermore, because the perfume particles are relatively large, their range of movement is small, making this method inefficient and wasteful.

[0041] The atomizing head provided by this utility model can be used in atomizers that perform gas-liquid mixing atomization or atomizers based on ultrasonic atomization principles. During operation, the atomized mist enters the exhaust channel 111 through the connection port 113 and is then discharged through the exhaust port 112. Simultaneously, the essential oil droplets accumulated at the exhaust port 112, under the action of the spirally extending flow-guiding structure 114, have their surface tension disrupted, allowing the essential oil accumulated at the exhaust port 112 and within the atomization channel to easily flow from the exhaust port 112 to the connection port 113 along the spirally extending flow-guiding structure 114. This solves the problem of essential oil droplets, due to their high viscosity and surface tension, not easily falling back down.

[0042] In one embodiment, the connection port 113 may include a first connection port 113 for guiding mist into the mist exhaust channel 111 and a second connection port 113 for discharging essential oil into the essential oil bottle 2.

In this embodiment, the interior of the mist outlet body 11 is divided into an upper cavity 311 and a lower cavity 312 by a guide plate 31. The atomized gas first enters the larger space of the lower cavity 312, which can effectively eliminate noise and achieve a better gas-liquid mixing effect. The gas in the lower cavity 312 flows from the connection port 113 to the fragrance mist connection port 313, and then enters the upper cavity 311, further achieving a better noise reduction effect and gas-liquid mixing effect.

The spring-type drainage tube is located between the upper limit device 1112 and the guide plate 31, and its bottom abuts against the guide plate 31. The guide plate 31 has a fragrance mist connection port 313, which connects to the connection port 113 and the mist exhaust port 112. The guide plate 31 and the upper limit device 1112 work together to limit the upper and lower movement of the spring-type drainage tube. Simultaneously, the tubular channel 1111 provides circumferential limitation for the spring-type drainage tube.

[0046] refer to Figure 7-9 In a preferred embodiment, the flow guiding structure 3 further includes an upper flow guiding wall 32 and a lower flow guiding wall 33. The upper flow guiding wall 32 surrounds the upper side of the flow guiding plate 31 and extends upward, while the lower flow guiding wall 33 is located below the flow guiding plate 31 and extends downward.

The gas and liquid mix and atomize. The atomized mist enters the lower cavity 312 through the through hole 121 in the inner cavity of the connecting body 12. In this cavity, the gas and liquid are further mixed, and this cavity has a good noise reduction effect. The mist in the lower cavity 312 enters the small cavity 116 through the flow channel 34 and the aroma mist connecting port 313. The column 115 has a notch, which allows the mist in the small cavity 116 to enter the upper cavity 311 through the notch. The mist in the upper cavity 311 is discharged through the mist exhaust channel 111111 and the mist exhaust port 112112, thus achieving the aroma diffusion effect.

[0053] refer to Figure 13-14 As the diffuser emits aroma mist, essential oil droplets accumulate at the mist outlet 112112. The essential oil at the mist outlet 112112 breaks the tension of the essential oil under the action of the spring-type drainage tube, allowing the essential oil to flow into the upper cavity 311 under the action of gravity. Then, the essential oil enters the flow channel 34 through the notch on the column 115, through the aroma mist connection port 313, and falls into the lower cavity 312 under the action of gravity. Then, it enters the inner cavity of the connecting body 12 through the through hole 121 and falls into the essential oil bottle 2 under the action of gravity.
