[0028] The essential oil atomizing device in the present application mainly optimizes the structure of the air inlet cavity and the atomizing module to improve the air flow effect and atomization effect of the existing atomizing device, and to avoid the risk of ceramic piece dry burning in the cotton stick oil supply.

[0029] Referring to Figure 1 , and in combination with Figures 2-3 , the essential oil atomizing device in the present application, the main structure includes a shell 1, the shell 1 is detachably connected with a top cover 11, and the top cover 11 is provided with an air inlet baffle 12.

[0030] The shell 1 is provided with an air inlet 13, the air inlet 13 is communicated with an air inlet cavity 14 inside the shell 1, the air inlet baffle 12 is arranged opposite to the position of the air inlet 13, and the air inlet baffle 12 can block the air inlet and change the flow direction of the air flow.

[0031] The bottom of the air inlet cavity 14 is provided with a flow guide slope 15, and the setting of the flow guide slope 15 mainly includes two aspects of automatically returning the unatomized essential oil and optimizing the air inlet.

[0032] From the perspective of automatic backflow, the center of the shell 1 is provided with a center pipe 2 for installing an oil guide cotton stick 22, and the center pipe 2 is provided with a backflow hole 21, which is arranged at the top of the center pipe 2 and corresponds to the bottom of the flow guide slope 15.

[0033] Through the arrangement, the essential oil that is not atomized can flow back along the flow guide slope 15, enter through the backflow hole 21 at the top of the center pipe 2, and flow back to the oil guide cotton stick 22 installed in the center pipe 2, which can prevent the oil supply of the oil guide cotton stick 22 from being interrupted to a certain extent.

[0034] From the perspective of optimizing the air inlet flow, the slope surface of the flow guide slope 15 and the bottom edge of the air inlet baffle 12 form an air inlet gap of the air inlet cavity 14, and in combination with the slope surface structure of the flow guide slope 15, the air inlet gap can form a slant angle flow guide space.

[0035] The air inlet flow moves downward under the blocking action of the air inlet baffle 12, passes through the slant angle flow guide space of the flow guide slope 15, and is converted into a vortex flow state at the slope surface position of the flow guide slope 15, and then enters the subsequent atomization cavity 17. The vortex air inlet flow can spiral upward from the bottom of the atomization cavity 17 and carry the atomized essential oil particles out of the mist outlet 18 at the center of the top cover 11.

[0036] Through the arrangement, the turned air inlet flow can spiral through most of the space of the atomization cavity 17, and can fully carry the essential oil particles out.

The cotton sheet fastener 31 includes an elastic silica gel fastener, which can release the vibration energy of the atomization ceramic sheet 32 to a certain extent under the premise of reliably clamping and pressing the atomization cotton sheet 4, thereby avoiding the loosening of the atomization cotton sheet 4.

[0040] The driving assembly 5 specifically comprises a positive electrode conductive metal sheet 51, a conductive spring 53 and a driving plate 52, the positive electrode conductive metal sheet 51 mainly serves as a positive electrode power supply effect, is arranged on the top surface of the atomization ceramic sheet 32, the conductive spring 53 mainly serves as a negative electrode power supply effect, abuts against the bottom surface of the atomization ceramic sheet 32, can realize high-frequency vibration of the atomization ceramic sheet 32 after power supply, in combination with the pressure assembly of the cotton sheet fastener 31 on the atomization ceramic sheet 32, can make the atomization ceramic sheet 32 drive the atomization cotton sheet 4 to vibrate at high frequency, so that the essential oil guided to the atomization cotton sheet 4 is released in the high-frequency vibration state, and the essential oil particles are wrapped and output in the spiral flowing air flow.

[0041] Further, the driving plate 52 is suspendedly installed inside the shell 1, serving as a mounting structure basis of the driving assembly 5, and the conductive spring 53 is installed between the driving plate 52 and the atomization ceramic sheet 32.

[0044] Further, the essential oil atomization particle atomization outlet 18 is arranged at the center of the top cover 11, and the atomization cavity 17 and the atomization outlet 18 are staggered in the radial direction, so that the unatomized oil droplets can be prevented from being directly sprayed out.

[0045] Based on the high-frequency vibration of the atomization ceramic sheet 32 and the pressure assembly of the cotton sheet fastener 31 above the atomization ceramic sheet 32, the cotton sheet fastener 31 and the atomization cotton sheet 4 both comprise atomization particle avoiding holes 41, the atomization particle avoiding holes 41 are communicated with the space of the atomization cavity 17, and the essential oil particles under the action of high-frequency vibration can be guided out of the atomization particle avoiding holes 41 to the atomization cavity 17.

[0053] In the essential oil atomization device, the driving plate 52 activates the atomizing ceramic sheet 32, so that the atomizing ceramic sheet 32 generates 3 million times / second vibration to break the oil film, in combination with the structure of the optimized air inlet cavity 14 and the vortex air flow after the air inlet flow passes through the guide slope 15, the atomizing cavity 17 can carry the mist particles with a particle size ≤5 μm.

[0054] For the modular interface constituted by the pin integrated module, the customer only needs to provide a 5V power supply and a shell. The conductive contact 16 arranged on the shell 1 can supply power to the inside of the driving plate 52.
