An inner diameter of the atomization channel approaching the liquid ejecting port is greater than an inner diameter of the gas ejecting port to enable an intake gas flow from the gas inlet channel to form a negative pressure region at such site and to facilitate mixing of the liquid and gas to form an aerosol. The atomization channel defines an aerosol generating port configured to eject the aerosol. 
     Further, a step is formed between the gas ejecting port and the liquid ejecting port and configured to prevent a gas flow ejected from the gas ejecting port from directly impacting into the liquid ejecting port and thereby preventing the gas from entering the liquid inlet channel.

         D 2 ≥D 3, and 1/2 D 3 ≤L≤D 2. 
     Further, an inner diameter of the gas inlet channel gradually reduces in a direction from the gas inlet towards the gas ejecting port. 
     Further, an inner diameter of the liquid inlet channel gradually reduces in a direction from the liquid inlet towards the liquid ejecting port. 
     Further, the aerosol generating port is trumpet-shaped, an inner diameter of the aerosol generating port gradually increases in a direction away from the atomization channel. The gas inlet channel and the atomization channel are coaxially arranged, one end of the liquid inlet channel contacting the liquid ejecting port is arranged to be perpendicular to the atomization channel or at an acute angle with respect to the atomization channel. 
     The present application further provides an atomization device, which comprises the atomization nozzle as described in the above. 
     Further, the atomization device comprises: a casing, and a mounting frame arranged within the casing. The mounting frame is provided with a liquid storing bottle and a gas pump, and the mounting frame defines an atomization chamber and a gas flow channel in communication with the atomization chamber and configured to allow the gas generated from the gas pump to enter the atomization nozzle. The atomization nozzle is installed inside the gas flow channel, the liquid inlet channel of the atomization nozzle is in communication with the liquid storing bottle, and the aerosol generating port of the atomization nozzle is in communication with the atomization chamber. One end of the casing away from the liquid storing bottle defines an aerosol outlet, and the aerosol outlet is in communication with the atomization chamber. 
     Further, the mounting frame comprises: a mounting seat, a nozzle support connected and fixed to the mounting seat, and a gas pump support connected and fixed to the nozzle support. The mounting seat is in abut connection with the nozzle support to form the atomization chamber; the liquid storing bottle is installed within the mounting seat, the gas flow channel is arranged at the nozzle support, and the gas pump is installed at the gas pump support. 
     Further, two ends of the gas flow channel have a first gas guiding hole in communication with the gas pump and a second gas guiding hole in communication with the first gas guiding hole, respectively.

The atomization nozzle is installed at the second gas guiding hole. 
     Further, the mounting seat is provided with an accommodation chamber; the liquid storing bottle is detachably installed inside the accommodation chamber, and the bottle mouth of the liquid storing bottle is configured to be arranged at one end of the liquid storing bottle facing towards the atomization chamber. 
     Further, the atomization nozzle is installed above the bottle mouth of the liquid storing bottle, and the aerosol generating port of the atomization nozzle is disposed above the bottle mouth and faces towards the bottle mouth; 
     or alternatively, the atomization nozzle extends into the bottle mouth of the liquid storing bottle, the aerosol generating port of the atomization nozzle is disposed within the bottle mouth, and the atomization chamber is in communication with the bottle mouth. 
     BENEFICIAL EFFECT 
     The atomization nozzle and the atomization device provided by the present application have the following beneficial effects: 
     when compared with the prior art, the atomization nozzle provided by the present application comprises the nozzle body, which comprises: the gas inlet channel, the atomization channel, and the liquid inlet channel. One end of the gas inlet channel defines the gas inlet, the other end of the gas inlet channel defines the gas ejecting port, and the gas ejecting port and the atomization channel intercommunicate with each other. One end of the liquid inlet channel defines the liquid inlet, the other end of the liquid inlet channel defines the liquid ejecting port, and the liquid ejecting port and the atomization channel intercommunicate with each other. Gas generated from the gas pump is taken in via the gas inlet and pass through the gas ejecting port such that a high velocity gas flow is ejected and enters the atomization channel. Because the inner diameter of the liquid ejecting port approaching the atomization channel is greater than the inner diameter of the gas ejecting port, the intake gas flow of the gas inlet channel forms the negative pressure region at such site, such that the liquid from the liquid storing bottle passes through the liquid inlet to enter the liquid inlet channel and then be ejected via the liquid ejecting port. Under the impact of the high velocity gas flow, the liquid ejected from the liquid ejecting port forms fine aerosol droplets, which is ejected from the aerosol generating port. The sealing performance is good, the utilization efficiency of the gas flow is relatively high, and even in the case of low speed, a sufficient negative pressure can be formed to enable the liquid to be drawn into the atomization channel, thereby effectively improving the atomization efficiency, and solving the problem that the splitting type atomization nozzle in the prior art is oversized and inconsistent in atomization efficiency.

     Referring to  FIGS. 1-5 , an atomization nozzle  20  provided by the present application is illustrated. The atomization nozzle  20  may be applied to household atomization devices, such as atomization of essential oil or humidifiers. The atomization nozzle  20  comprises a nozzle body  201 . The nozzle body  201  comprises: a gas inlet channel  21 , an atomization channel  22 , and a liquid inlet channel  23 . The gas inlet channel  21  defines a gas inlet  211  at one end and a gas ejecting port  212  at the other end, and the gas ejecting port  212  and the atomization channel  22  intercommunicate with each other. The gas inlet  211  is configured to be connected with a gas pump in order to transport the gas generated from the gas pump to the atomization channel  22 . The liquid inlet channel  23  defines a liquid inlet  231  at one end and a liquid ejecting port  232  at the other end, and the liquid ejecting port  232  and the atomization channel  22  intercommunicate with each other. The liquid inlet  231  is configured to be connected to a liquid storing bottle storing a liquid, for example, a liquid storing bottle storing an essential oil. An inner diameter of the atomization channel  22  approaching the liquid ejecting port  232  is greater than an inner diameter of the gas ejecting port  212 , that is, when the inner diameter of the gas ejecting port  210  is D 1  and the inner diameter of the atomization channel  22  is D 2 , then D 2 &gt;D 1 . By designing the inner diameter of the atomization channel  22  approaching the liquid ejecting port  232  to be greater than the inner diameter of the gas ejecting port  212 , such that an intake gas flow of the gas inlet channel  21  forms a negative pressure region at such site, which facilitates the mixing of the liquid and gas to form the aerosol. The atomization channel  22  defines an aerosol generating port  221  configured to eject the aerosol. 
     The atomization nozzle  20  provided by the present application, when compared with the prior art, comprises the nozzle body  201 , which comprises: the gas inlet channel  21 , the atomization channel  22 , and the liquid inlet channel  23 . One end of the gas inlet channel  21  defines the gas inlet  211 , the other end of the gas inlet channel  21  defines the gas ejecting port  212 , and the gas ejecting port  212  and the atomization channel  22  intercommunicate with each other. One end of the liquid inlet channel  23  defines the liquid inlet  231 , the other end of the liquid inlet channel  23  defines the liquid ejecting port  232 , and the liquid ejecting port  232  and the atomization channel  22  intercommunicate with each other. Gas generated from the gas pump is taken in via the gas inlet  211  and pass through the gas ejecting port  212  such that a high velocity gas flow is ejected and enters the atomization channel  22 . Because the inner diameter of the liquid ejecting port  232  approaching the atomization channel  22  is greater than the inner diameter of the gas ejecting port  212 , the intake gas flow of the gas inlet channel  21  forms the negative pressure region (Venturi effect) at such site, such that the liquid from the liquid storing bottle passes through the liquid inlet  231  to enter the liquid inlet channel  23  and then be ejected via the liquid ejecting port  232 . Under the impact of the high velocity gas flow, the liquid ejected from the liquid ejecting port  232  forms fine aerosol droplets (Bernoulli&#39;s fluid mechanics), which are ejected from the aerosol generating port  221 . The sealing performance is good, the utilization efficiency of the gas flow is relatively high, and even in the case of low speed, a sufficient negative pressure can be formed to enable the liquid to be drawn into the atomization channel  22 , thereby effectively improving the atomization efficiency, and solving the problem that the splitting type atomization nozzle  20  in the prior art is oversized and inconsistent in atomization efficiency. 
     Further, as shown in  FIGS. 4-5 , as a specific embodiment of the atomization nozzle provided by the present application, a step  24  as illustrated in  FIG. 5  is formed between the gas ejecting port  212  and the liquid ejecting port  232 . The step  24  can effectively prevent the high velocity gas flow ejected from the gas ejecting port  212  from directly impacting into the liquid ejecting port  232 , which would otherwise make the gas flow back to the external liquid storing bottle and make the liquid storing bottle to bubble. 
     Further, as shown in  FIGS. 4-5 , as a specific embodiment of the atomization nozzle  20  provided by the present application, the inner diameter of the atomization channel  22  is defined as D 2 , and the atomization channel  22  is a channel with an equivalent inner diameter, that is, the inner diameter of the atomization channel  22  is equivalent at any positions. An inner diameter of the liquid ejecting port  232  is defined as D 3 , a distance from one end of the step  24  contacting the gas ejecting port  212  to the center of the liquid ejecting port  232  is defined as L, and the following relationship among D 2 , D 3 , and L is to be satisfied: D 2 ≥D 3 , and 1/2D 3 ≤L≤D 2 . Due that D 2 ≥D 3  and 1/2D 3 ≤L≤D 2 , the atomization efficiency can be greatly improved. 
     Further, as shown in  FIGS. 4-5 , as a specific embodiment of the atomization nozzle  20  provided by the present application, an inner diameter of the gas inlet channel  21  gradually reduces in a direction from the gas inlet  211  towards the gas ejecting port  212 , such that the gas entering the gas inlet  211  is pressurized and therefore ejected out of the gas ejecting port  212  at a high velocity. 
     Further, as shown in  FIGS. 4-5 , as a specific embodiment of the atomization nozzle  20  provided by the present application, an inner diameter of the liquid inlet channel  23  gradually reduces in a direction from the liquid inlet  231  towards the liquid ejecting port  232 , such that the pressure for drawing the liquid is improved, and the flow velocity is increased, thereby improving the atomization efficiency. 
     Further, as shown in  FIGS. 4-5 , as a specific embodiment of the atomization nozzle  20  provided by the present application, the aerosol generating port  221  is trumpet-shaped, an inner diameter of the aerosol generating port  221  gradually increases in a direction away from the atomization channel  22 , thereby improving the ejection efficiency of the atomized droplets. 
     Further, as shown in  FIGS. 4-5 , as a specific embodiment of the atomization nozzle  20  provided by the present application, the gas inlet channel  21  and the atomization channel  22  are coaxially arranged, one end of the liquid inlet channel  21  contacting the liquid ejecting port  232  is arranged to be perpendicular to the atomization channel  22  or at an acute angle with respect to the atomization channel  22 . Specifically, the atomization channel  22 is arranged at a bottom of the gas inlet channel  21  (facing downwards), which makes the gas flow within the atomization channel  22  is guided downwards, thereby effectively solving refluxing difficulty in the atomization nozzle  20  in the prior art. 
     Referring to  FIGS. 6-18 , the present application further provides an atomization device. The atomization device may be an aromatherapy device or a humidifier. The atomization device comprises the above-described atomization nozzle  20 . Further, The atomization device comprises a casing  100  and a mounting frame  300  arranged within the casing  100 . The mounting frame  300  is provided with a liquid storing bottle  10  and a gas pump  30 , and the mounting frame  300  defines an atomization chamber  310  and a gas flow channel  51  in communication with the atomization chamber  310  and configured to allow the gas generated from the gas pump  30  to enter the atomization nozzle  20 . The atomization nozzle  20  is installed inside the gas flow channel  51 , the liquid inlet channel  23  of the atomization nozzle  20  is in communication with the liquid storing bottle  10 , and the aerosol generating port  221  of the atomization nozzle  20  is in communication with the atomization chamber  310 . One end of the casing  10  away from the liquid storing bottle  10  defines an aerosol outlet  120 , and the aerosol outlet  120  is in communication with the atomization chamber  310 . Specifically, as shown in  FIG. 8 , the casing  100  has an inner cavity  110  in which the mounting frame  300  is installed. 
     Further, referring to  FIGS. 7-8 , as a specific embodiment of the atomization device provided by the present application, the aerosol generating port  221  faces the bottle mouth  11  and is opposite the aerosol outlet  120 , in this way, the distance between the atomization nozzle  20  and the aerosol outlet  120  is stretched, the gas pressure produced by the atomization nozzle  20  faces downwards, which enables the relatively large atomized droplets to directly and quickly flow back to the liquid storing bottle  10  via the open bottle mouth  11  while enabling the relatively small atomized droplets to raise and be ejected out via the aerosol outlet  120 , such that the length of the atomization turbulence is much longer, secondary atomization is prone to be formed, thereby improving the atomization efficiency. 
     Further, referring to  FIGS. 8-10 , the atomization nozzle  20  is installed above the bottle mouth of the liquid storing bottle  10 , and the aerosol generating port  221  of the atomization nozzle  20  is disposed above the bottle mouth  11  and faces towards the bottle mouth  11 . The direction of the gas flow within the atomization chamber faces downwards, which can effectively solve the refluxing of the atomization nozzle in the prior art. Specifically, the liquid inlet of the atomization nozzle  20  may be in connection with the liquid storing bottle  10  via a pipette  53 . In another preferred embodiment of the present application, the atomization nozzle  20  extends into the bottle mouth  11  of the liquid storing bottle  10 , the aerosol generating port  221  of the atomization nozzle  20  is disposed within the bottle mouth  11 , and the atomization chamber  310  is in communication with the bottle mouth  11 . Because the aerosol generating port  221  is disposed within the bottle mouth  11 , the gas pressure produced by the atomization nozzle  20  enables the relatively large atomized droplets to directly and quickly flow back to the liquid storing bottle  10  while enabling the relatively small atomized droplets to raise and escape from the open bottle mouth  11  and then be ejected out via the aerosol outlet  120 , such that the length of the atomization turbulence is much longer, secondary atomization is prone to be formed, thereby improving the atomization efficiency. 
     Further, referring to  FIGS. 8-10 , the mounting frame comprises: a mounting seat  40 , a nozzle support  50  connected and fixed to the mounting seat  40 , and a gas pump support  60  connected and fixed to the nozzle support  50 . The mounting seat  40  is in abut connection with the nozzle support  50  to form the atomization chamber  310 . The liquid storing bottle  10  is installed within the mounting seat  40 , the gas flow channel  51  is arranged at the nozzle support  50 , and the gas pump  30  is installed at the gas pump support  60 . By connecting the mounting seat  40 , the nozzle support  50 , the gas pump support  60  as a whole, the installation process can be simplified, and the installation efficiency is therefore improved. 
     Further, referring to  FIGS. 8-10 , as a specific embodiment of the atomization device provided by the present application, the atomization device further comprises a fastener (not shown) configured to connect and fix the mounting seat  40 , the nozzle support  50 , and the gas pump support  60 .

The fastener may be a blot, which passes through the first through hole  401 , the second through hole  501 , and the third through hole  601 , respectively, and achieve the connection and fixation with a screw, which further achieves the connection and fixation of the mounting seat  40 , the nozzle support  50 , and the gas pump support  60 . 
     Further, referring to  FIGS. 15-18 , as a specific embodiment of the atomization device provided by the present application, two ends of the gas flow channel  51  have a first gas guiding hole  511  in communication with the gas pump  30  and a second gas guiding hole  512  in communication with the first gas guiding hole  511 . Specifically, a top end of the gas flow channel  51  is provided with a first gas guiding hole  511 , and a bottom end of the gas flow channel  51  is provided with the second gas guiding hole  512 . A center axis of the first gas guiding hole  511  and a center axis of the second gas guiding hole  512  are coaxially arranged. In another preferred embodiment of the present application, the center axis of the first gas guiding hole  511  and the center axis of the second gas guiding hole  512  are staggered from each other, that is, the center of the first gas guiding hole  511  and the center of the second gas guiding hole  512  are not arranged along the same axis. The atomization nozzle  20  is installed at the second gas guiding hole  512 , by staggering the center of the first gas guiding hole  511  and the center of the second gas guiding hole  512  from each other, the gas flow generated from the gas pump  30  is prevented from aligning the atomization nozzle  20 , thereby effectively lowering the noise generated by the gas pump  30 . 
     Further, referring to  FIGS. 8-14 , as a specific embodiment of the atomization device provided by the present application, the first gas guiding hole  511  is provided therein with a first seal member  513 . By the arrangement of the first seal member  513 , the gas pump  30  is prevented from gas leakage, which improves the gas utilization efficiency of the gas. 
     Further, referring to  FIGS. 8-10 , as a specific embodiment of the atomization device provided by the present application, a check valve  514  is installed inside the gas flow channel  51 . The arrangement of the check valve  514  enables the gas from the gas pump  30  to enter the gas flow channel  51  in one direction and the same time prevents the gas pump  30  from being corroded due to the backflow of the liquid of the atomization nozzle  20  into the gas pump  30 , which would otherwise result in reduction of the service life of the gas pump  30 . 
     Further, referring to  FIGS. 10, 15, and 18 , as a specific embodiment of the atomization device provided by the present application, the nozzle support  50  is further provided with an aerosol discharge channel  52 . A top of the aerosol discharge channel  52  corresponds to a position of the aerosol outlet  120  and is in communication with the aerosol outlet  120 , and a bottom of the aerosol discharge channel  52  is in communication with the atomization chamber  310 , therefore the aerosol discharged channel  52  is configured to guide the relatively small aerosol droplets in the atomization chamber  310  towards the aerosol outlet  120  where the aerosol droplets are ejected, thereby achieving the discharge of the aerosol. 
     Further, referring to  FIGS. 8, 10, and 11 , as a specific embodiment of the atomization device provided by the present application, the mounting seat  40  is provided with an accommodation chamber  402 . The liquid storing bottle  10  is detachably installed inside the accommodation chamber  402 , and the bottle mouth  11  is configured to be arranged at one end of the liquid storing bottle  10  facing towards the atomization chamber  310 . Specifically, the bottle mouth  11  of the liquid storing bottle  10  is in an open state rather than a sealed state. Specifically, the liquid storing bottle  10  is detachably fixed within the accommodation chamber  402  via threaded connection or interference contact, which is convenient for replace the liquid storing bottle  10  timely, and the installation is very simple and convenient. It should be noted that the connection mode between the liquid storing bottle  10  and the mounting seat  40  is limited thereto. For example, in other preferred embodiment of the present application, the datable connection and fixation between the liquid storing bottle  10  and the mounting seat  40  can be realized by snap-fitting. Further, the connection site between the bottle mouth  11  and the accommodation chamber  402  is provided with a third seal member  111  as shown in  FIG. 10 , and the arrangement of the third seal member  111  can avoid liquid leakage.
