nano-scale cold mist with a diameter of 0.1-5im spreads it in surrounding air through high

frequency electronic oscillation generated by an ultrasonic oscillation equipment, so as to

achieve the effect of deodorization and fragrance addition. In addition, the aroma diffuser

atomizes water, which can maintain a high humidity in the room to a certain extent, and

alleviate the phenomenon of dry indoor environment.

[0003] For example, Chinese Publication No. CN109999213A disclosed a method for forming

varying mist from an aroma diffuser and an aroma diffuser applied therefor. The aroma diffuser

disclosed therein includes a body including an upper housing, a base and a middle housing

the life quality.

Summary

[0005] An object of the present application is to provide an aroma diffuser which achieves a

plurality of functions, a reasonable structure, and a compact layout.

[0006] The above object of the present application is achieved by the following technical

solution.

[0007] The aroma diffuser provided in the present application includes an atomization cavity

and a wind cavity, and the atomization cavity is in communication with the wind cavity via a

wind channel. A mist outlet is disposed at a top of the atomization cavity, an ultrasonic

oscillation device is fixed at a bottom of the atomization cavity, a blower is fixed in the wind

cavity, and an air inlet is disposed on a wall of the wind cavity. The wind cavity is wrapped

around the periphery of the atomization cavity and is separate from the atomization cavity. A

touch display panel is disposed at the outer wall of the wind cavity, and a main control board is

fixed in the wind cavity. There provided on the main control board are a micro control unit and

a WIFI unit, an oscillation drive unit, a display drive unit, a touch panel control unit and a power

supply unit which are respectively connected with the micro control unit. The touch display

panel is connected with the touch panel control unit and the display drive unit, the ultrasonic

oscillation device is connected with the oscillation drive unit, and the blower is connected with

the micro control unit.

[0008] In the above-mentioned technical solution, the wind cavity is wrapped around the

periphery of the atomization cavity, the wind cavity is separate from the atomization cavity,

and the main control board, the touch display panel, and the blower are all disposed inside the

wind cavity. On one hand, such a structure is more reasonable, and the layout is more compact;

and on the other hand, almost all circuit components are disposed inside the wind cavity, so

that the circuit components can be effectively prevented from being damaged by water during

the process of adding water, replacing water, and washing the atomization cavity. Furthermore,

as the circuit components are disposed inside the wind cavity, the blower can not only achieve

atomizing, but also dissipate the heat from the circuit components, which improves energy utilization, prevents the circuit components from overheating, and improves the service life thereof. As the micro control unit is connected with the WIFI unit, the oscillation drive unit, the display drive unit, and the touch panel control unit, the aroma diffuser has functions of touch control, display, and timed mist off, which achieves intelligentization and a plurality of functions.

[0009] In a preferred embodiment, the main control board is provided with a temperature

sensor connected with the micro control unit.

[0010] In the above-mentioned technical solution, the temperature sensor real time detects

the environment temperature and sends detected data to the micro control unit, so as to

conveniently detect and display the real time environment temperature.

[0011] In a preferred embodiment, the wind cavity is a hollow cavity formed by engaging a first

half housing and a second half housing. A first opening is disposed at a top of the wind cavity,

the atomization cavity is snap connected at the first opening and positioned in the wind cavity,

and a second opening is disposed at the top of the atomization cavity corresponding to the first

opening. An atomization cavity cover is disposed at the second opening, the mist outlet is

disposed at the atomization cavity cover, and the atomization cavity cover covers both the first

opening and the second opening.

[0012] In the above-mentioned technical solution, the atomization cavity is snap connected at

the first opening, and positioned in the wind cavity, so that the atomization cavity and the wind

cavity form a sheath structure, in which case the volume of the wind cavity is the total volume

of the whole aroma diffuser, providing a more reasonable and compact structure.

[0013] In a preferred embodiment, a liquid baffle is connected with the atomization cavity

cover at a position inside the atomization cavity where the mist outlet is, and a gap is provided

between the liquid baffle and an inner wall of the atomization cavity cover for a mist to pass

through.

[0014] In the above-mentioned technical solution, since it has the tendency to cause spray of

water when the ultrasonic oscillation device produces high frequency electronic oscillation to

break down water molecules and dissolved plant essential oil into cold mists, the liquid baffle

can prevent the spray of water from being splashed from the mist outlet, ensuring the fineness

of the mist spread out of the mist outlet.

[0015] In a preferred embodiment, a first snap recess is disposed within an inner wall of the

wind cavity and at the periphery of the first opening, and a first snap arm for fitting in the first

snap recess is disposed at the periphery of an outer wall at the open end of the atomization

cavity, so that the atomization cavity is snap connected with the wind cavity by fitting the first

snap arm in the first snap recess.

[0016] In the above-mentioned technical solution, the atomization cavity is connected with the

wind cavity, which eliminates the need of connectors, reduces the number of parts while

guaranteeing a robust connecting structure, and provides the product with simplicity, integrity

and long life service.

[0017] In a preferred embodiment, an insertion piece is disposed at the bottom and the side

wall of the atomization cavity, and an insertion slot mating with the insertion piece is fixed

inside the wind cavity.

[0018] In the above-mentioned technical solution, the structure adopting the insertion piece

and the insertion slot achieves the connection of the atomization cavity with the wind cavity

from the bottom of the atomization cavity. This prevents the relative movement between the

atomization cavity and the wind cavity, while supporting the wind cavity from the bottom of

the atomization cavity, which spreads the relative force between the atomization cavity and the

wind cavity by increasing force bearing points.

[0019] In a preferred embodiment, an annular insertion arm is disposed at one side of the

atomization cavity cover facing the atomization cavity, and the annular insertion arm is

engaged with the inner wall of the atomization cavity. When the atomization cavity cover is

covered on the first opening and the second opening, the side edge of the atomization cavity

cover conforms to the periphery of the first opening.

[0020] In the above-mentioned technical solution, the atomization cavity cover is inserted in

the second opening of the atomization cavity through the annular insertion arm, which

achieves the connection of the atomization cavity cover and the atomization cavity and avoids

loosening. The side edge of the atomization cavity cover conforms to the periphery of the first

opening, preventing the forming of a gap leading to air leakage.

[0021] In a preferred embodiment, a recess is formed in one side wall of the atomization cavity,

and the recess is recessed inwards relative to a cavity body of the atomization cavity and

extends from the bottom to the top of the atomization cavity. An air hole in communication

with the atomization cavity is disposed in the recess, and the air hole is positioned at the top of

the atomization cavity and forms the wind channel together with the recess.

[0022] In the above-mentioned technical solution, the wind channel formed by the recess has

the effect of gathering up the wind and improving the wind pressure, so as to guarantee that

the wind entering the atomization cavity has a certain pressure to make sure that the mist can

be steadily spread out of the mist outlet, while, on the other hand, forming the wind channel

from the recess in the side wall of the atomization cavity enables a reasonable and compact

structure and convenient processing.

[0023] In a preferred embodiment, a touch screen mounting port is disposed on the side wall

of the wind cavity, the touch display panel is covered on the touch screen mounting port, and a

pressing ring snap connected with the wind cavity is disposed at the periphery of the touch display panel, so that the touch display panel is fixedly sandwiched between the pressing ring and the housing of the wind cavity.

[0024] In the above-mentioned technical solution, the touch display panel is connected with

the wind cavity, which eliminates the need of connectors, reduces the number of parts while

and long life service.

[0025] In a preferred embodiment, the main control board is in parallel with the touch display

panel, a main control board holder is fixedly sandwiched between and in parallel with the touch

display panel and the main control board, and is integrated with the main control board by

snap connection via a supporting foot connected on the main control board holder. The main

control board holder conforms to the touch display panel, engraved holes corresponding to

individual function units are disposed on the main control board, a force is passed between a

touch control area on the touch display panel and the main control board via a compression

spring, and the compression spring is extended through and positioned via the main control

board holder.

[0026] In the above-mentioned technical solution, the main control board holder realizes

display and touch control in separate areas, and also realizes the installation of the main

control board, which has a protective effect on the main control board.

[0027] In summary, the present application has the following beneficial effects:

1. the wind cavity is wrapped around the atomization cavity, and is separate from the

atomization cavity, and the main control board, the touch display panel, and the blower are all

disposed inside the wind cavity. On one hand, such structure is more reasonable, and the

layout is more compact; on the other hand, almost all circuit components are disposed inside

the wind cavity, so that the circuit components can be effectively prevented from being damaged by water during the process of adding water, replacing water, and washing the atomization cavity. Furthermore, as the circuit components are disposed inside the wind cavity, the blower can not only achieve an atomizing effect, but also dissipate the heat from the circuit components, which improves energy utilization, prevents circuit components from overheating, and improves the service life;

2. the wind cavity, the atomization cavity and the wind cavity, the touch display panel

and the wind cavity, the main control board holder and the wind cavity are all snap connected

DETAILED DESCRIPTION

[0036] The present application will be further described in detail below in connection with the

drawings.

the aroma diffuser includes a housing including an atomization cavity 1 and a wind cavity 2; the

wind cavity 2 is a hollow cavity formed by engaging a first half housing 201 and a second half

housing 202 respectively positioned on the left and right sides; a first opening 203 is provided

at the center of the top of the wind cavity 2; the atomization cavity 1 is snap connected at the first opening 203, and positioned in the wind cavity 2, that is, the first half housing 201 and the second half housing 202 are wrapped around the atomization cavity 1 from two sides, so that the atomization cavity 1 and the wind cavity 2 form a sheath structure, in which case the volume of the wind cavity 2 is the total volume of the whole aroma diffuser, providing a more reasonable and compact structure. As shown in FIG.2 and FIG. 3, a first snap recess 2031 is provided within the inner wall of the wind cavity 2 and at the periphery of the first opening 203, a snap arm 2032 for fitting in the first snap recess 2031is provided at the periphery of the outer wall of the open end of the atomization cavity 1, so that the atomization cavity 1 is in snap connection with the wind cavity 2 by snapping the first snap arm 2032 in the first snap recess

2031, which eliminates the need of connectors, reduces the number of parts while

and long life service. As shown in FIG. 2, an insertion piece 102 is horizontally provided at the

bottom and the side wall of the atomization cavity 1, and an insertion slot 1021 mating with the

insertion piece 102 is fixed inside the wind cavity 2. The structure adopting the insertion piece

102 and the insertion slot 1021 achieves the connection of the atomization cavity 1 with the

wind cavity 2 from the bottom of the atomization cavity 1. This prevents the relative movement

between the atomization cavity 1 and the wind cavity 2, while supporting the wind cavity 2

from the bottom of the atomization cavity 1, which spreads the relative force between the

atomization cavity 1 and the wind cavity 2 by increasing force bearing points.

[0038] As shown in FIG. 3 and FIG. 4, an ultrasonic oscillation device 12 is fixed at the bottom of

the atomization cavity 1, which produces high frequency electronic oscillation to break down

water molecules and dissolved plant essential oil into cold mists. As shown in FIG. 2, a second

opening 100 is disposed at the top of the atomization cavity 1 where the first opening 203 is. As

shown in FIG. 3, the side wall of the atomization cavity 1 assumes a step shape, and the diameter of the second opening 100 of the atomization cavity 1 is larger than that of the inner diameter thereof. As shown in FIG. 2 and FIG. 3, an atomization cavity cover 101 is provided at the second opening 100, and an annular insertion arm 1011 is provided at the side of the atomization cavity cover 101 facing the atomization cavity 1, which is engaged with the inner wall of the atomization cavity 1 to achieve the connection of the atomization cavity cover 101 with the atomization cavity 1 and avoid loosening. When the atomization cavity cover 101 is covered on the first opening 203 and the second opening 100, the side edge of the atomization cavity cover 101 is fit with the periphery of the first opening 203, so that the atomization cavity cover 101 covers both the first opening 203 and the second opening 100, preventing the forming of a gap leading to air leakage.

[0039] As shown in FIG. 1 and FIG. 2, a mist outlet 11 is disposed at the center of the

atomization cavity cover 101, a liquid baffle 111 is bolt connected at the position inside the

atomization cavity 1 inside the atomization cavity 1 where the mist outlet 11 is, and a gap is

provided between the liquid baffle 111 and the atomization cavity cover 101 for the mist to

pass through. Since it has the tendency to cause spray of water when the ultrasonic oscillation

device 12 produces high frequency electronic oscillation to break down water molecules and

dissolved plant essential oil into cold mists, the liquid baffle 111 can prevent the spray of water

from being splashed from the mist outlet 11, ensuring the fineness of the mist spread out of the

mist outlet 11.

[0040] As shown in FIG. 4, a blower 21 is fixed in the wind cavity 2, which is vertically disposed

within the cavity of the second half housing 202, and an air inlet 210 is disposed on the vertical

wall of the second half housing 202. The atomization cavity 1 is in communication with the

The blower 21 pumps air from the outside of the wind cavity 2 to the inside of the wind cavity 2, so that flowing air passes through the wind channel 3 and enters the atomization cavity 1, where the ultrasonic oscillation device 12 produces high frequency electronic oscillation to break down water molecules and dissolved plant essential oil into cold mists, which is brought out of the mist outlet by the air flowed from the air hole 30 and spread into the environment. On one hand, the wind channel 3 formed by the recess has the effect of gathering up the wind and improving the wind pressure, so as to guarantee that the wind entering the atomization cavity 1 has a certain pressure to assure that the mist can be steadily spread out of the mist outlet 11, while, on the other hand, forming the wind channel 3 from the recess in the side wall of the atomization cavity 1 enables a reasonable and compact structure and convenient processing.
