The utility model provides an atomizer 100.

In the embodiment of the present invention, please refer to fig. 2 to 4 in combination, the nebulizer 100 includes a housing 111, a shielding case 112, and an airflow sensor 120. An air outlet channel 1012 is formed in the outer shell 111, the isolation shell 112 is detachably mounted in the outer shell 111, a capillary air channel 102 is formed in the isolation shell 112 and used for forming a liquid channel bottleneck, the capillary air channel 102 is provided with an inlet 1021 and an outlet 1022, and the inlet 1021 and the outlet 1022 penetrate through the isolation shell 112. The inlet 1021 is communicated with the air outlet channel 1012, a closed installation cavity 103 is formed between the isolation shell 112 and the inner wall of the outer shell 111, and the outlet 1022 is communicated with the installation cavity 103. The airflow sensor 120 is installed in the installation cavity 103.

Be equipped with gas outlet channel 1012 in atomizer 100's the shell 111, gas outlet channel 1012 is used for communicateing the external world, still is equipped with stock solution storehouse and atomizing core in the shell 111, and the stock solution storehouse has the liquid outlet, and the liquid outlet contact in atomizing core and stock solution storehouse to the atomizing liquid outflow in the stock solution storehouse of being convenient for and through the heating of atomizing core in order to form the smog state. Or the atomization core is arranged in the liquid storage bin, so that after the atomization core is attached to the atomized liquid in the liquid storage bin, the atomized liquid can be heated and forms a smoke state. In order to facilitate the user to inhale the smoke, the atomizing core can be disposed in the air outlet channel 1012, so that the smoke formed after the atomizing core heats the atomized liquid can pass through the air outlet channel 1012 and be delivered into the user's mouth. Or, the atomizing core is connected to the atomizing chamber, which is further connected to the air outlet channel 1012, so that the smoke generated in the atomizing core can enter the air outlet channel 1012 through the atomizing chamber and be sent to the mouth of the user through the air outlet channel 1012. Specifically, atomizing core is linked together including leading liquid spare and the piece that generates heat, and the liquid spare that leads is linked together with the stock solution storehouse, and the piece that generates heat is located one side that the liquid spare deviates from the stock solution storehouse, and the piece that generates heat is used for heating the adsorbed atomized liquid of liquid spare that leads so that form smog state.

It can be understood that when the atomizer 100 is not in operation, the smoke passing through the air outlet channel 101 will flow down from the air outlet channel 1012 under the influence of gravity after being condensed and hung on the wall when encountering cold, and if the airflow sensor 120 is disposed in the air outlet channel 1012, the atomized liquid will easily flow to the surface of the airflow sensor 120, which in turn will affect the normal operation of the airflow sensor 120. The utility model discloses through still being provided with the insulated shell 112 that has capillary air flue 102 in shell 111 among the technical scheme, capillary air flue 102 is used for forming the liquid channel bottleneck, and enclose jointly between the inner wall of insulated shell 112 and shell 111 and close and form confined installation cavity 103, the entry 1021 and the ventiduct 1012 intercommunication of the capillary air flue 102 that set up on the insulated shell 112, the export 1022 and the installation cavity 103 intercommunication of capillary air flue 102, such structural design makes confined installation cavity 103 only communicate through capillary air flue 102 and ventiduct 1012, consequently, atomized liquid can at first pass through capillary air flue 102 after flowing down from ventiduct 1012. When the atomized liquid does not enter the capillary air passage 102, the air pressure in the mounting cavity 103 is equal to the air pressure in the capillary air passage 102, the air outlet passage 1012 and the outside, but after the atomized liquid flows into the capillary air passage 102, the air in the mounting cavity 103 is squeezed, so that the air pressure in the mounting cavity 103 is increased. It can be understood that, atomizing liquid deepens into the one side that capillary air flue 102 is close to installation cavity 103 more, then the atmospheric pressure in the installation cavity 103 is bigger, thereby subsequent atomizing liquid is difficult more and more to flow into to capillary air flue 102 depths, when the atmospheric pressure in the gas outlet channel 1012 and the hydraulic pressure sum of atomizing liquid equals the atmospheric pressure in the installation cavity 103, then the balanced state has been realized, consequently atomizing liquid is the shutoff in capillary air flue 102's liquid channel bottleneck department, no longer to flowing to depths, and then can not flow to in the installation cavity 103, avoid atomizing liquid to take place to the condition on the air current sensor 120. In addition, when the atomizer 100 is in an inoperative state, positive pressure is not generated in the air outlet channel 1012, so that the atomized liquid blocked in the capillary air channel 102 is not forced to be pressed into the mounting cavity 103 any more, that is, the atomized liquid is not pushed in the direction of the mounting cavity 103 any more, and at this time, the atomized liquid has a liquid sealing effect in the capillary air channel 102. By installing the airflow sensor 120 in the installation cavity 103, it can be ensured that the atomized liquid does not flow into the airflow sensor 120. When the airflow sensor 120 is connected with the electronic components, the atomized liquid can be prevented from leaking onto the electronic components along the airflow sensor 120 to cause damage to the electronic components.

Further, when the user needs to reuse the atomizer 100, the atomizer 100 is in an open state, the airflow sensor 120 in the atomizer 100 is also opened, the user sucks smoke through the air outlet of the air outlet channel 1012, a negative pressure is generated in the air outlet channel 1012 at this time, so that the atomized liquid in the capillary air channel 102 flows to a negative pressure region, and further the air pressure in the installation cavity 103 changes, and meanwhile, the airflow sensor 120 arranged in the installation cavity 103 senses the change of the air pressure in the installation cavity 103, and further the airflow sensor 120 sends an instruction, so that the atomizer 100 normally works, namely, the atomization core and other components in the atomizer 100 are controlled to normally work. It is understood that if there is no residual atomized liquid on the inner wall of the outlet channel 1012 of the atomizer 100, there is naturally no flow of atomized liquid into the capillary air passage 102 and the mounting cavity 103, and the air pressure in the outlet channel 1012 and the mounting cavity 103 is kept the same.

Additionally, the utility model discloses through setting up an isolation shell 112 among the technical scheme, be formed with capillary air flue 102 in this isolation shell 112, make this capillary air flue 102 can become an independent module. Further, a separation case 112 provided with the capillary air passage 102 is detachably installed in the outer case 111, thereby facilitating a user to selectively replace and install the separation case 112. In addition, by arranging the independent isolation shell 112 and arranging the capillary air passage 102 in the isolation shell 112, the capillary air passage 102 with a complicated structure is prevented from being directly arranged in the shell 111, so that the forming process of the shell 111 is simplified, and the obstruction to the installation of other parts in the shell 111 is also avoided. It is understood that, after the isolation shell 112 is installed in the housing 111, it and the inner wall of the housing 111 can together enclose a closed space, which is the installation cavity 103. With this arrangement, the installation cavity 103 is not separately provided, but the installation cavity 103 is formed while the insulating case 112 is installed at a specific position within the outer case 111. In order to ensure that the inlet 1021 of the capillary passage 102 communicates with the outlet channel 1012, the inlet 1021 of the capillary passage 102 may penetrate out of the isolation housing 112 in the direction of the outlet channel 1012. Similarly, in order to ensure that the outlet 1022 of the capillary air passage 102 communicates with the installation cavity 103, the outlet 1022 of the capillary air passage 102 may penetrate to the outside of the isolation housing 112 in the direction of the installation cavity 103.

The utility model discloses technical scheme makes this capillary air flue 102 form an solitary module through detachably installation a set of housing 112 that has capillary air flue 102 in shell 111 for the dismouting of being convenient for, and still simplified the forming process of shell 111, avoid directly forming capillary air flue 102 in shell 111 and lead to the more complicated problem of the preparation technology of shell 111. In addition, the inlet 1021 of the capillary air passage 102 is communicated with the air outlet passage 1012, the mounting cavity 103 is a closed mounting cavity 103, the mounting cavity 103 is only communicated with the outlet 1022 of the capillary air passage 102, and at least one liquid passage bottleneck is formed between the capillary air passage 102 and the air flow sensor 120, so that when smoke in the air outlet passage is cooled and becomes condensed atomized liquid, the atomized liquid firstly enters the capillary air passage 102 and flows along the capillary air passage 102 when flowing down from the air outlet passage 1012, and meanwhile, the air in the mounting cavity 103 is squeezed to increase the air pressure. When the atomized liquid flows into the capillary air passage 102 and passes through a section of the capillary air passage 102, because the inner diameter of the capillary air passage 102 is very thin, the atomized liquid does not immediately flow to the bottom of the mounting cavity 103 under the action of gravity, but continuously moves downwards and deeply along with the atomized liquid entering the capillary air passage 102, the gas in the mounting cavity 103 is continuously extruded, and the gas pressure is continuously increased, until the gas pressure in the mounting cavity 103 gradually reaches a state equal to the sum of the liquid pressure of the atomized liquid and the atmospheric pressure in the gas outlet passage 1012, the atomized liquid stops continuously flowing to the deep part of the capillary air passage 102 under the resistance action of the gas pressure in the mounting cavity 103, so the atomized liquid is blocked in the capillary air passage 102, and the stagnation position of the atomized liquid in the capillary air passage 102 at the moment forms a liquid passage bottleneck, thereby preventing the surface of the gas flow sensor 120 in the mounting cavity 103 from being adhered by the dripped atomized liquid, preventing the gas flow sensor 120 from being damaged by the atomized liquid, improving the service life of the gas flow sensor 120, and also preventing the possibility that electronic components electrically connected with the gas flow sensor 120 cannot receive a trigger signal of the gas flow sensor 120.

Specifically, as shown in fig. 4, a plurality of baffles 130 are disposed in the isolation shell 112, the baffles 130 are alternately disposed, a capillary groove 131 is formed between every two adjacent baffles 130, a plurality of capillary grooves 131 are formed, and the capillary grooves 131 are communicated end to form the capillary passage 102.

So set up, make the capillary air flue 102 that forms after a plurality of capillary grooves 131 end to end intercommunication be U type air flue, S type air flue, the crooked air flue that forms by a plurality of U type air flues end to end or the crooked air flue that forms by a plurality of S type air flues end to make this capillary air flue 102 length longer, then play the effect of liquid seal after the certain degree of depth of atomizing liquid to capillary air flue 102, avoid atomizing liquid to get into in the installation cavity 103.

In addition, it can be understood that, in the capillary air passage 102 of the present embodiment, the plurality of baffles 130 are staggered at intervals to form the plurality of capillary grooves 131 that are communicated end to end, so that only one baffle 130 is arranged between two adjacent capillary grooves 131, that is, the baffles 130 can be used as the groove walls of two adjacent capillary grooves 131 at the same time, so that no more useless isolation space is arranged between two adjacent capillary grooves 131, the space occupied by the capillary air passage 102 is smaller, and further, the components in the housing assembly of the atomizer 100 can be arranged more compactly, which is convenient for achieving the effect of miniaturization of the atomizer 100.

Referring to fig. 2 and 4, based on the above-mentioned scheme that the plurality of baffles 130 are alternately arranged, and a capillary groove 131 is formed between every two adjacent baffles 130, in another embodiment, the opening of the inlet 1021 is directed upward, and the extending direction of the capillary groove 131 is the same as the direction of the inlet 1021.

With such an arrangement, after the atomized liquid flows into the capillary air passage 102 from the inlet 1021, the atomized liquid can directly flow into the bottom of the capillary groove 131 close to the air outlet passage 1012 under the action of gravity, that is, into the position where the capillary groove 131 close to the air outlet passage 1012 is far from the inlet 1021, which is the bottle neck portion of the capillary air passage 102, and the atomized liquid is easy to form a liquid seal state after being accumulated on the bottle neck portion. It can be understood that, when the pressure of the installation cavity 103 reaches to the sum of the pressure of the atomized liquid and the atmospheric pressure after the atomized liquid enters the capillary groove 131 to a certain depth, the atomized liquid stays in the capillary groove 131 and does not flow into the installation cavity 103, thereby ensuring that no atomized liquid flows into the installation cavity 103. At this time, the liquid level in the two capillary grooves 131 communicating with the bottle neck portion will be different, wherein the liquid level in the capillary groove 131 close to the air outlet channel 1012 is higher than the liquid level in the adjacent capillary groove 131.

Specifically, as shown in fig. 3 and 4, the inlet 1021 passes through the top end of the insulation case 112, and the outlet 1022 passes through the sidewall of the insulation case 112.

Through penetrating the top of isolation shell 112 with entry 1021, then can guarantee that atomized liquid can flow downwards to in the capillary air flue 102 after this entry 1021 to make atomized liquid get into behind the capillary air flue 102 the gas in the extrusion installation cavity 103, make the atmospheric pressure increase in the installation cavity 103, the gas in the installation cavity 103 can resist the hydraulic pressure of atomized liquid and the atmospheric pressure sum in the gas outlet channel 1012, thereby realizes the liquid seal effect of capillary.

Further, as shown in fig. 3, the airflow sensor 120 is mounted on a side wall of the insulation case 112 provided with the outlet 1022, and communicates with the outlet 1022.

The airflow sensor 120 is mounted on the side wall of the isolation shell 112 provided with the outlet 1022 and communicated with the outlet 1022 of the capillary air passage 102, so that the airflow sensor 120 and the isolation shell 112 provided with the capillary air passage 102 are assembled together, when the isolation shell 112 is mounted in the housing 111, the isolation shell and the inner wall of the housing 111 can jointly enclose to form the mounting cavity 103, and meanwhile, the airflow sensor 120 can be arranged in the mounting cavity 103, so that the mounting process is simplified, and the problem that the airflow sensor 120 is difficult to mount in the mounting cavity 103 through the capillary air passage 102 is solved.

Specifically, the airflow sensor 120 is detachably mounted on the sidewall of the isolation housing 112, and may be connected by a snap connection, a magnetic attraction connection, or a screw connection, for example. Or the airflow sensor 120 may be attached to the sidewall of the insulation case 112 by means of bonding.

Of course, in other embodiments, the airflow sensor 120 may not be disposed on the sidewall of the isolation housing 112, but may be disposed in a manner spaced apart from the isolation housing 112. In order to facilitate the installation of the airflow sensor 120 in the installation cavity 103, an installation opening is opened in a portion of the housing 111 forming a wall of the installation cavity 103, the airflow sensor 120 is installed in the installation cavity 103 from the installation opening, and a sealing cover is provided at the installation opening to seal the installation cavity 103, so that the installation cavity 103 is only communicated with the outlet 1022 of the capillary air passage 102.

Further, as shown in fig. 4, the outlet 1022 is opened to the groove wall of the capillary groove 131 distant from the inlet 1021.

By providing the outlet 1022 on the wall of the capillary groove 131 distant from the inlet 1021, the outlet 1022 is distanced from the inlet 1021, and the atomized liquid in the capillary groove 131 does not reach a state where the flow of the atomized liquid has stopped, and thus the atomized liquid flows from the outlet 1022 to the mounting chamber 103.

Further, in order to achieve better capillary action, the gap between two opposite walls of the capillary groove 131 needs to be set smaller, and in this embodiment, the distance between every two adjacent baffles 130 is defined as D2, and then D2 is greater than or equal to 0.5mm and less than or equal to 1.5mm.

The distance D2 between each adjacent two of the baffles 130 may be specifically 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, or 1.5mm. Through setting the interval D2 between every two adjacent baffles 130 to be not less than 0.5mm, then be convenient for when normally working, the atomized liquid can flow to in the gas outlet channel 1012 from the notch department of capillary groove 131, and then makes air current sensor 120 can feel the atmospheric pressure in the installation cavity 103 and change, guarantees that atomizer 100 can normally work. By setting the distance D2 between every two adjacent baffles 130 to be not more than 1.5mm, it is avoided that the distance between two opposite groove walls of the capillary groove 131 is too large to form a capillary action, and thus the atomized liquid cannot be stably sealed in the capillary passage 102.

Further, the utility model discloses interval D2 between every two adjacent baffles 130 that can prefer among the technical scheme is 1.0mm, so set up, then can guarantee atomizer 100 normal during operation on the one hand, airflow sensor 120 can experience the atmospheric pressure of installation cavity 103 and change, and on the other hand can also guarantee the effectual capillary action of capillary groove 131 for atomized liquid stops when climbing certain degree of depth along capillary groove 131 promptly, with the state that realizes the liquid seal, avoids atomized liquid to leak to airflow sensor 120 on.

Further, the sum of the lengths of the plurality of capillary grooves 131 is defined as L2, and L2 is 5mm. Ltoreq.L 2. Ltoreq.30 mm.

Set total length L2 through with a plurality of capillary grooves 131 to not less than 5mm, make the total length of capillary air flue 102 long enough to can guarantee that atomized liquid is when the depths extrusion gas to capillary air flue 102, can then can't resist the atmospheric pressure in the installation cavity 103 when atomized liquid enters into certain degree of depth, then reach balanced state, avoid atomized liquid to carry out in the installation cavity 103, and then guarantee that the air current sensor 120 in the installation cavity 103 adheres to the atomized liquid who reveals.

It will be appreciated that the longer the total length of the plurality of capillary grooves 131, the better the capillary effect, but at the same time, the more space it takes up. By setting the total length of the plurality of capillary grooves 131 to be not greater than 30mm, it is ensured that the atomized liquid can be blocked in the capillary grooves 131 without entering the mounting cavity 103, and on the premise that the capillary air passages 102 formed by the plurality of capillary grooves 131 occupy too much space, thereby achieving the effect of miniaturization of the atomizer 100. Specifically, the total length L2 of the plurality of capillary grooves 131 in the present invention may be 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, or the like.

Further, as shown in fig. 2, the atomizer 100 further includes an air inlet channel 1011 communicating with an air outlet channel 1012, the air outlet channel 1012 and the air inlet channel 1011 form a main air channel 101, the air outlet channel 1012 is disposed above the air inlet channel 1011, and an inlet 1021 of the capillary air channel 102 communicates with the air outlet channel 1012.

The inlet channel 1011 is a channel for the outside air to enter, and the outlet channel 1012 is a channel for the atomized mist and the mixed air to exit. Further, the atomizer 100 may further have a suction nozzle, which communicates with the air outlet passage 1012. It can be understood that, since the outlet channel 1012 is disposed above the inlet channel 1011, it is in accordance with the usage habit of the user, and is convenient for smoke to enter the mouth of the user from the outlet channel 1012 upwards. By connecting the inlet 1021 of the capillary air passage 102 with the air outlet passage 1012, when the atomized liquid flows into the capillary air passage 102 after being condensed, because the inner diameter of the capillary air passage 102 is very small, the atomized liquid does not flow to the bottom of the mounting cavity 103 immediately due to the action of gravity, but continuously moves down and goes deep along with the atomized liquid entering the capillary air passage 102, the gas in the mounting cavity 103 is continuously squeezed, and the air pressure is continuously increased, until the air pressure in the mounting cavity 103 gradually reaches a state equal to the sum of the hydraulic pressure of the atomized liquid and the atmospheric pressure in the air outlet passage 1012, the atomized liquid stops continuously flowing to the deep part of the capillary air passage 102 due to the resistance action of the air pressure in the mounting cavity 103, so that the atomized liquid is blocked in the capillary air passage 102, and the position where the atomized liquid stagnates in the capillary air passage 102 at this time forms a bottleneck of the liquid passage, thereby preventing the surface of the air flow sensor 120 in the mounting cavity 103 from being adhered by the dripped atomized liquid, preventing the air flow sensor 120 from being damaged, improving the service life of the air flow sensor 120, and further preventing the electronic components electrically connected with the air flow sensor 120 from receiving the possibility of the air flow from triggering.
