Detailed ways

In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the related drawings. The preferred embodiments of the present application are shown in the accompanying drawings. However, the application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that a thorough and complete understanding of the disclosure of this application is provided.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terms used herein in the description of the invention are for the purpose of describing particular embodiments only and are not intended to limit the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in FIG. 1 and FIG. 2 , an atomizer air duct structure 1 provided in an implementation of the present application includes a liquid storage tank 11 provided with an atomization space 111, and an air duct pipe 12 provided with a flow channel through hole 121; The air duct 12 is connected to the liquid storage tank 11, and the air provided by the air duct 12 forms an air current for blowing the atomized particles in the atomizing space after entering the atomizing space 111 The liquid storage tank 11 further includes a diversion channel 13, the outlet of the diversion channel 13 is connected to the spray port 112, and the inlet of the diversion channel 13 is located in the atomization space 111 and faces away from the The air flow channel (that is, the air in the air flow channel does not face the inlet of the guide channel 13). It can be understood that the air flow channel in this embodiment is the flow direction of the air when the air enters the atomization space 111 from the outlet of the flow channel through hole 121 , rather than the air flow in the atomization space except the flow channel through hole. The direction in which other parts at the outlet of 121 flow.

In an optional embodiment, the air duct 12 extends into the atomization space 111 from the bottom of the liquid storage tank 11 , there can be multiple guide channels 13 and multiple spray ports 112 . And each guide channel 13 may correspond to one spray port 112 .

Further, the number of the spray ports 112 and the guide channels 13 can be set to multiple (2, 4, 6, etc.) according to actual requirements.

Specifically, the working principle of the air duct structure 1 of the atomizer is: in the working state, the liquid in the atomization space 111 becomes atomized with different diameters under the action of the ultrasonic atomization device 2 particles, and fill the atomization space 111; the air duct 12 provides air and enters the atomization space 111, and forms an air flow channel for blowing the atomized particles, and the guide channel 13 The orientation of the inlet deviates from the air flow channel, so that the air blown out of the flow channel through hole 122 will not directly enter the guide channel 13, but needs to flow in the atomization space 111 for a certain path. It is sprayed from the spray port 112 to the external environment through the guide channel 13 . When the atomized particles in the atomization space 111 are blown through the air flow channel by the flow channel through holes 121, the atomized particles with larger diameters will fall where they are due to the addition of their own gravity and wind. At the bottom of the atomization space 111 , the atomized particles with smaller diameters can flow along with the wind, so as to be sprayed from the spray port 112 to the external environment through the guide channel 13 . Therefore, the quality of the atomized particles sprayed by the atomizer and the experience of the product are improved, and the potential safety hazard caused by the spraying of large-diameter atomized particles from the atomizer is avoided.

In one embodiment, as shown in FIG. 1 , FIG. 2 and FIG. 4 , the top of the liquid storage tank 11 is further provided with an annular surrounding arm 1143 ; the annular surrounding arm 1143 is provided with a connection to the atomization space 111 and the air outlet 11431 of the annular installation space, the air provided by the air duct 12 enters the atomization space 111 through the air outlet 11431 to form an air flow channel. Understandably, when the air duct 12 is installed in the annular installation space, the protruding portion 1141 is embedded in the flow channel through hole 121 .

Further, the protruding part 1141 is arranged at the middle position of the top of the liquid storage tank 11, and a preset distance is left between the top of the liquid storage tank 11 and the top of the air duct 12, so that the The air in the flow channel through hole 121 can be blown into the atomization space 111 from the top of the air channel pipe 12 . Further, the annular surrounding arm 1143 is installed on the top of the liquid storage tank 11 and is located outside the protruding part 1141, and the annular surrounding arm 1143 is spaced from the protruding part 1141, and the flow The top of the pipe 12 can be inserted into the annular installation space; the annular surrounding arm 1143 is provided with an air outlet 11431 connecting the atomization space 111 and the annular installation space, specifically, the air flowing out of the guide channel 13 passes through the annular The installation space enters the atomization space 111 from the air outlet 11431 , and an air flow channel for entering the atomization space 111 is formed at the air outlet 11431 .

In an optional embodiment, the air flow channel of the air outlet 11431 forms an air flow channel with the main flow direction toward the bottom of the liquid storage tank 11 after passing through the air outlet channel 134. That is, after the air flow channel formed by the air outlet 11431 passes through the air outlet channel 134 , the direction of the air flow channel can be controlled if the air outlet channel 134 has a certain length, so that the main flow direction is formed toward the bottom of the liquid storage tank 11 . Therefore, when the air flow channel drives the atomized particles to flow, the larger atomized particles are more likely to be blown to the bottom of the liquid storage tank 11, that is, return to the bottom of the atomization space 111 to be re-atomized. The small particles will flow along with the air flow channel, and will be ejected from the spray port 112 through the guide channel 13 under the action of the air pressure difference, so as to ensure the small diameter of the atomized particles blown out.

Specifically, the flow channel through hole 121 enters the air outlet channel 134 through the air outlet 11431, and the air in the air outlet channel 134 will drive the atomized particles in the atomization space 111 to flow downward, The atomized particles with larger diameters are more likely to be blown to the bottom of the atomization space 111 under the addition of their own gravity and wind force; the atomized particles with smaller diameters flow upward and pass through the guide channel 13 is sprayed from the spray port 112 to the external environment; thereby further improving the quality of the atomized particles sprayed by the atomizer and the experience of the product, avoiding the safety caused by the atomizer dispensing large-diameter atomized particles hidden danger.
