Referring to fig. 1-3, fig. 1-3 respectively show a perspective view of an ultrasonic atomizer 100 in one direction, an exploded view of one view angle, and a cross-sectional view of one direction according to an embodiment of the invention. The ultrasonic atomizer 100 includes a suction nozzle 10 and a liquid storage portion 20, the suction nozzle 10 is mountable on the liquid storage portion 20, the liquid storage portion 20 is used for storing an atomized liquid matrix 30, and performing ultrasonic vibration on the liquid matrix 30 to atomize at least a portion of the liquid matrix 30 to generate aerosol for a user to inhale, and the user can inhale the aerosol generated by ultrasonic atomization through the suction nozzle 10. The liquid matrix 30 may be a tobacco liquid or a liquid medicine, so the ultrasonic atomizer 100 provided in the embodiment of the present invention may be used in the medical or electronic cigarette field.

The housing of the suction nozzle 10 is provided with a first fastening position (not shown) and a second fastening position (not shown), and a sliding rail 13 defined between the first fastening position and the second fastening position, wherein the first fastening position and the second fastening position 12 are used for being in fastening connection with the liquid storage portion 20, when the suction nozzle 10 is mounted on the liquid storage portion 20, the suction nozzle 10 and the liquid storage portion 20 can be in fastening connection with each other at the first fastening position 11, or can be in fastening connection with each other at the second fastening position 12, that is, the suction nozzle 10 has a first assembling position and a second assembling position relative to the liquid storage portion 20, the first assembling position corresponds to the first fastening position 11, the second assembling position corresponds to the second fastening position 12, and the suction nozzle 10 can move between the first assembling position and the second assembling position through the sliding rail 13. For example, when the suction nozzle 10 needs to be moved from the first assembly position to the second assembly position, the suction nozzle group 0 may be pressed with force, the suction nozzle 10 may be moved from the first assembly position to the second assembly position along the slide rail 13 by the pressing force, or the liquid storage portion 20 may be pushed up with force, which may also cause the suction nozzle 10 to be moved from the first assembly position to the second assembly position.

The housing of the mouthpiece 10 is further provided with an air inlet hole 12 and an air outlet hole 11, the air inlet hole 12 is used for providing an air flow inlet for external air to enter the atomizer 100, and the air outlet hole 11 is used for providing an air flow outlet for aerosol generated after ultrasonic atomization to escape the atomizer 100. When a user uses the atomizer 100 to suck at the air outlet 11, negative pressure is generated inside the atomizer 100, external air enters the atomizer 100 through the air inlet 12 and flows to the air outlet 11 through an air flow channel between the air inlet 12 and the air outlet 11, and aerosol generated after ultrasonic atomization is carried and flows to the air outlet 11 in the flowing process, so that the user can suck the aerosol at the air outlet 11.

With reference to fig. 3, fig. 3 is a schematic cross-sectional view of the nozzle 10 and the liquid storage portion 20 in the second assembly position, and fig. 4 is a schematic cross-sectional view of the nozzle 10 and the liquid storage portion 20 in the first assembly position, referring to fig. 4. The suction nozzle 10 is internally and fixedly provided with an air inlet pipe 15 and an air outlet pipe 16 with two open ends, the side wall of the air inlet pipe 15 is provided with a first through hole 151, and the air inlet hole 12 is communicated to the inside of the air inlet pipe 15 through the first through hole 151, so that external air can enter the inside of the air inlet pipe 15 through the air inlet hole 12. The air outlet pipe 16 is communicated with the air outlet hole 11, and aerosol generated after ultrasonic atomization can flow to the air outlet hole 11 through the air outlet pipe 16.

The opening shapes of the air inlet pipe 15 and the air outlet pipe 16 serving as extrusion members relative to one end of the liquid storage 20 are inclined, at least one part of the pipe body can be sharp by the inclined opening to form an extrusion end 152 and an extrusion end 161, the extrusion end 152 and the extrusion end 161 are used for extruding end seals of the liquid storage 20, so that at least one part of the air inlet pipe 15 and the air outlet pipe 16 can extend into the liquid storage 20, external air can enter the liquid storage 20 through the air inlet pipe 15, aerosol generated after ultrasonic atomization in the liquid storage 20 is carried into the air outlet pipe 16, and the aerosol flows to the air outlet hole 11 through the air outlet pipe 16. When the suction nozzle 10 is connected to the liquid storage portion 20 at the first assembly position, the sealing members at the end of the liquid storage portion 20 are not pressed by the air inlet pipe 15 and the air outlet pipe 16, and the sealing members at the end of the liquid storage portion 20 of the air inlet pipe 15 and the air outlet pipe 16 are in an abutting state or keep a certain distance from the sealing members at the end of the liquid storage portion 20, as shown in fig. 4. When the suction nozzle 10 is connected to the liquid storage portion 20 at the second assembly position, the air inlet pipe 15 and the air outlet pipe 16 squeeze the sealing member at the end of the liquid storage portion 20 and pierce the sealing member at the end of the liquid storage portion 20 and then enter the liquid storage portion 20, as shown in fig. 3.

With reference to fig. 5, fig. 5 shows an exploded view of the liquid storage portion 20 at a viewing angle, and fig. 3 is also combined. The reservoir 20 includes a first seal 21, a first bracket 22, a first shutter member 23, a second bracket 24, a second shutter member 25, a second seal 26, an ultrasonic atomizing assembly 27, and a bottom cover 28. The first bracket 22 is fixedly connected with the bottom cover 28 to form a housing part of the liquid storage part 20; the second holder 24 and the second seal 26 are fixed in contact with each other in the axial direction of the atomizer 100 inside the housing of the liquid reservoir 20; the ultrasonic atomization assembly 27 is arranged at the bottom of the liquid storage part 20 and is used for performing ultrasonic vibration on the liquid matrix 30 to generate aerosol; the first shielding member 23 and the second shielding member 25 are used for blocking liquid drops sputtered by the liquid matrix 30 from entering the air inlet pipe 15 or the air outlet pipe 16 during ultrasonic atomization; the first seal 21 is used to seal the end of the reservoir 20 against leakage of the liquid matrix 30 in the reservoir 29.

With respect to the first sealing member 21, please refer to fig. 6, fig. 6 shows a schematic perspective view of the first sealing member 21 in one direction, and fig. 3 is also combined. The first sealing member 21 is made of a soft rubber material, for example, rubber, silica gel or latex material, so that the first sealing member 21 can be connected with the first bracket 22 in a matching manner by interference. The first seal 21 is formed with a first seal hole 211 and a second seal hole 212, and the first seal hole 211 and the second seal hole 212 are sealed by weak silica gel. When the suction nozzle 10 is connected to the liquid storage portion 20 at the second assembly position, the extrusion end 152 of the air inlet pipe 15 and the extrusion end 161 of the air outlet pipe 16 respectively extrude the silica gel of the first sealing hole 211 and the second sealing hole 212 and pierce the silica gel of the first sealing hole 211 and the second sealing hole 212, so that the air inlet pipe 15 and the air outlet pipe 16 respectively penetrate the first sealing hole 211 and the second sealing hole 212.

It should be noted that, the pressing end 152 and the pressing end 161 are configured to be in an inclined state, so that when the silica gel in the first sealing hole 211 and the second sealing hole 212 is punctured, the portion that is punctured by the pressing will not break, thereby preventing the broken silica gel from falling into the atomizer 100, and blocking the air flow from entering or exiting; on the other hand, since the silicone rubber has elasticity, the squeeze-pierced portion can be restored to the original position by the elastic restoring force after the air inlet pipe 15 or the air outlet pipe 16 is separated from the first sealing hole 211 or the second sealing hole 212.

By means of the first sealing member 21, when the atomizer 100 is not needed, the suction nozzle 10 is connected with the liquid storage portion 20 at the first assembly position, the silica gel of the first sealing hole 211 and the second sealing hole 212 is not pierced, the liquid matrix 30 of the liquid storage cavity 29 is completely sealed in the liquid storage portion 20, and therefore the leakage probability of the liquid matrix 30 of the atomizer 100 when the atomizer 100 is not needed, for example, when the atomizer 100 is stored or transported, can be effectively reduced. On the other hand, since the external air can only enter the liquid storage portion 20 through the air inlet pipe 15 or the air outlet pipe 16, when the atomizer 100 is not needed to be used, that is, the suction nozzle 10 is connected with the liquid storage portion 20 at the first assembling position, the air inlet pipe 15 and the air outlet pipe 16 do not puncture the first sealing member 21, the first sealing member 21 can effectively isolate the external air from entering the liquid storage portion 20, the performance of the liquid matrix 30 in the liquid storage portion 20 is effectively maintained, and the long-time contact deterioration of the liquid matrix 30 and the air is prevented.

The first support 22 is a hollow cylindrical body, and has a proximal end and a distal end, the proximal end is used for being connected with the suction nozzle 10, the distal end is used for being connected with the base 28, the proximal end surface extends towards the suction nozzle 10 to form a first air duct 221 and a second air duct 222, and the first sealing element 21 is in interference fit with one end tube surfaces of the first air duct 221 and the second air duct 222. The distal opening is provided, and the first shielding member 23, the second bracket 24, the second shielding member 25, the second seal 26 and the ultrasonic atomizing assembly 27 are all mounted on the hollow part of the first bracket 22 through the distal opening of the first bracket 22. When the suction nozzle 10 is connected with the liquid storage portion 20 at the second assembly position, the extrusion end 152 of the air inlet pipe 15 and the extrusion end 161 of the air outlet pipe 16 respectively pierce the silica gel of the first sealing hole 211 and the second sealing hole 212, the air inlet pipe 15 and the air outlet pipe 16 penetrate through the first sealing hole 211 and the second sealing hole 212 and simultaneously extend into the first air guide pipe 221 and the second air guide pipe 222, so that the air inlet pipe 15 and the air outlet pipe 16 are respectively in fluid communication with the first air guide pipe 221 and the second air guide pipe 222.

The second support 24 has a hollow structure, and one end of the second support is abutted against the first support 22, and the other end is abutted against the second sealing member 26, so that the second support 24 is abutted between the first support 22 and the second sealing member 26. A third air duct 241 and a fourth air duct 242 extend in the direction of the bottom cover 28 at the end of the second bracket 24 abutting the first bracket 22, and the third air duct 241 and the fourth air duct 242 are respectively in fluid communication with the first air duct 221 and the second air duct 222. The second holder 24 is provided with an opening at an end thereof abutting against the second seal 26 so that at least a part of the second seal 26 can be accommodated into the hollow portion of the second holder 24 through the opening end, thereby holding the second seal 26.

The second seal 26 is also hollow and has an open end facing the second support 24 and an open end facing the bottom cover 28, the open end facing the second support 24 extending into a hollow region of the second support 24, the open end facing the bottom cover 28 for receiving the ultrasonic atomizing assembly 27 to retain the ultrasonic atomizing assembly 27 in the hollow region of the second seal 26 such that the second seal 26 is in communication with the hollow region of the second support 24, i.e., the hollow region acts as a liquid reservoir 29 of the atomizer 100, the liquid reservoir 29 for storing the liquid matrix 30. Since the liquid storage chamber 29 is defined by the hollow areas of the first bracket 24 and the second seal 26, the liquid storage chamber 29 is divided into a first portion 291 and a second portion 292, the first portion 291 is formed by the hollow area of the second bracket 24, and the second portion 292 is formed by the hollow area of the second seal 26. The second sealing member 26 is made of a soft rubber material, for example, rubber, silica gel or latex, and the first sealing member 26 is assembled with the inside of the housing of the liquid reservoir 20 by interference, so as to prevent the liquid matrix 30 in the liquid reservoir cavity 29 from leaking out of the atomizer 100 through the assembly gap between the first bracket 22 and the bottom cover 28. Meanwhile, a part of the first portion 291 is used as an atomization chamber of the atomizer 100, and is used for providing a space for releasing aerosol generated by ultrasonic atomization, and the atomization chamber is respectively in fluid communication with the third air guide pipe 241 and the fourth air guide pipe 242, so that external air can enter the atomization chamber through the air inlet pipe 15, the first air guide pipe 221 and the third air guide pipe 241 to form an air inlet channel, and then the atomized aerosol is carried to flow to the air outlet hole 12 from the fourth air guide pipe 242 and the second air guide pipe 222 to form an air outlet channel. It is easy to understand that the third air duct 241 can be used as an air inlet of the atomization chamber, and external air enters the atomization chamber through the third air duct 241; the fourth air duct 242 may be used as an air outlet of the atomizing chamber, and the external air enters the atomizing chamber and then carries the aerosol through the fourth air duct 242 into the air outlet channel.

Because the second sealing member 26 is made of soft rubber material, the ultrasonic atomization assembly 27 can be tightly matched with the hollow area of the first sealing member 26 in an interference manner, so that the ultrasonic atomization assembly 27 is directly soaked in the liquid storage cavity 29. The ultrasonic atomizing assembly 27 generally includes an atomizing plate 271 for providing high frequency oscillation, and when the ultrasonic atomizing assembly 27 is immersed in the liquid storage chamber 29, the atomizing plate 271 is immersed in the liquid storage chamber 29, that is, the atomizing plate 271 is directly in contact with the liquid substrate 30. When the ultrasonic atomizing assembly 27 is energized, the atomizing plate 271 resonates at a high frequency and bulges the surface of the liquid substrate 30, cavitation occurs around the bulged liquid surface, atomizing the liquid substrate 30 into an aerosol of small molecules, that is, atomizing the liquid substrate 30 into an aerosol, and releasing the generated aerosol into the atomizing chamber.

When a user needs to use the atomizer 100, the atomizer 100 is started, the ultrasonic atomization assembly 27 is electrified, the atomization piece 271 generates high-frequency resonance to atomize the liquid matrix 30 to generate aerosol, the user sucks the atomizer 100 at the air outlet 11 to enable negative pressure to be generated inside the atomizer 100, external air enters the atomizer 100 through the air inlet 12, and the aerosol generated by the atomizer 100 is carried to the air outlet 11 to escape the atomizer 100 for the user to inhale.

It should be noted that, since the ultrasonic atomizing assembly 27 is directly immersed in the liquid storage cavity 29, and the atomizing plate 271 is directly contacted with the liquid matrix 30, in order to maintain a relatively ideal atomizing effect, a predetermined height range is generally required between the liquid surface of the liquid matrix 30 and the atomizing plate 271, and the predetermined height range is related to selection of the atomizing plate 271, for example, the predetermined liquid surface height is different when the oscillation frequency of the atomizing plate 271 is different, and the manufacturer can set the liquid surface height range according to the specific atomizing plate 271 selected.

Further, in order to maintain the predetermined height range of the liquid surface of the atomizing plate 271 and the liquid substrate 30 after the atomizer 100 is used for a certain period of time, in this embodiment, the hollow area of the second sealing member 26 is used as the second portion 292 of the liquid storage chamber 29, and compared with the first portion 291 of the liquid storage chamber 29, the second portion 292 is in a retracted shape, that is, the cavity size of the second portion 292 along the radial direction of the atomizer 100 is smaller than the cavity size of the first portion 291 along the radial direction of the atomizer 100, so that when the atomizer 100 is used for a certain period of time, the liquid substrate 30 in the liquid storage chamber 29 is excessively consumed, and the remaining liquid substrate 30 is concentrated in the second portion 292, and when the liquid substrate 30 is concentrated in the second portion 292 due to the smaller radial size of the cavity of the second portion 292, a certain height will be correspondingly provided, so that the liquid surface of the atomizing plate 271 and the remaining liquid substrate 30 can still be maintained within the predetermined height range.

As described above, in the present embodiment, the atomizing sheet 271 is directly immersed in the liquid storage chamber 29, and the atomizing sheet 271 is directly in contact with the liquid medium 30, and the liquid medium 30 in the liquid storage chamber 29 is not atomized by the liquid guide (not shown) being introduced into the atomizing sheet 271, so that the liquid medium 30 in the present embodiment is atomized by the high-frequency vibration generated by the atomizing sheet 271, and at the same time, a part of the liquid medium 30 is also sputtered in the direction of the third air duct 241 and the fourth air duct 242 by the high-frequency vibration. Because the third air duct 241 and the fourth air duct 242 are respectively in fluid communication with the air inlet hole 12 and the air outlet hole 11, the sputtered liquid can flow to the air inlet hole 12 and the air outlet hole 11 through the third air duct 241 and the fourth air duct 242, and the liquid substrate 30 leaks when flowing to the air inlet hole 12, and is inhaled by the user when flowing to the air outlet hole 11, and bad use experience is brought to the user.

Therefore, the atomizer 100 further includes the first shielding member 23 described above, and the first shielding member 23 is configured to block liquid droplets sputtered during ultrasonic atomization from sputtering into the air inlet channel, while also preventing the liquid matrix 30 from flowing to the air inlet hole 12 and the air outlet hole 11 through the air inlet channel or the air outlet channel when the atomizer 100 is inverted. As shown in fig. 7, referring also to fig. 3 in combination, fig. 7 shows a schematic perspective view of the first shutter member 23 in one direction.

Specifically, the first shielding member 23 is a soft rubber member such as silicone rubber or rubber. The first shielding member 23 is formed with a first insertion hole 231 and a second insertion hole 232, and the first air duct 221 and the second air duct 222 are respectively inserted into the first insertion hole 231 and the second insertion hole 232 and are connected with the first insertion hole 231 and the second insertion hole 232 in an interference fit manner. Meanwhile, the first shielding member 23 is also in interference abutting connection with the first support 22 and the second support 24 to seal an assembly gap between the first support 22 and the second support 24, so as to prevent air flow from escaping from the assembly gap between the first support 22 and the second support 24, and maintain the air tightness inside the atomizer 100.

The first shielding member 23 further includes a silicone valve sheet 2311 disposed at the first insertion hole 231, so as to provide shielding on the air inlet channel, preventing sputtered droplets generated during ultrasonic atomization or leakage of the liquid matrix 30 from the air inlet hole 12 through the third air duct 241 when the atomizer 100 is inverted; and a silica gel valve sheet 2321 disposed in the second plug hole 232, so as to provide shielding on the air outlet channel, and prevent the sputtered droplets generated during ultrasonic atomization or the inverted liquid matrix 30 of the atomizer 100 from leaking from the air outlet hole 11 through the fourth air duct 242.

Further, the first plug hole 231 and the second plug hole 232 are respectively provided with a plurality of silica gel valve plates 2311 and 2321, the silica gel valve plates 2311 and 2321 are uniformly distributed in the first plug hole 231 and the second plug hole 232, and a gap 233 is kept between any two silica gel valve plates, so that it is easy to understand that the gap 233 is very small so as to sufficiently block the sputtered liquid drops or liquid substrates 30 from passing through the gap 233. The gap 233 is provided to enable each silica gel valve block 2311 to be turned over towards the third air duct 241 independently under the action of the air pressure of the air flow after the air flow enters the air inlet channel or the air outlet channel, and a gap is formed after the silica gel valve block 2311 is turned over, so that the external air can enter the third air duct 241 through the first air duct 221 and further flow into the atomization chamber through the gap, the gap can be used as the air inlet for the external air to enter the atomization chamber, and the external air can enter the atomization chamber through the air inlet; the silica gel valve sheet 2321 can be turned over towards the second air duct 222 independently under the action of air pressure of the air flow, and a gap is formed after the silica gel valve sheet 2321 is turned over, so that the atomized aerosol carried by the external air can enter the second air duct 222 through the fourth air duct 242 and then is left at the air outlet hole 11. It is easy to understand that, since the first shielding silicone 2311 and the second shielding silicone 2321 are soft rubber members, after the air pressure of the air flow disappears, the first shielding silicone 2311 and the second shielding silicone 2321 will recover to the initial state under the action of the elastic restoring force, so as to block the liquid matrix 30 from flowing to the air inlet hole 12 or the air outlet hole 11 when the atomizer 100 is inverted.

Further, because of the gap 233 between the silicone sheets, although the size of the gap 233 is very small, a small portion of the sputtered droplets still flows through the gap 233 to the outlet 11. Accordingly, the atomizer 100 further comprises a second shielding member 25, the second shielding member 25 further serving to block sputtered liquid from entering the outlet channel. As shown in fig. 8 and 9, fig. 8 and 9 show perspective views of the second shielding member 25 in two directions thereof.

Specifically, the second shielding member 25 is configured as a tube, and the second shielding member 25 is made of a soft rubber material such as rubber or silicone, and has an opposite open end 251 and a closed end 252, and a side wall 253 extending between the open end 251 and the closed end 252. The end surface of the open end 251 is provided with a second through hole 2511, the end surface of the closed end 252 is a closed plane, the side wall 253 is provided with at least one third through hole 2531, and the third through hole 2531 is in fluid communication with the second through hole 2511. The open end 251 is inserted into the fourth air duct 242 by means of an interference fit, and seals the gap between the inner wall of the fourth air duct 242 and the outer wall of the second shielding member 25, and since the end face of the shielding end 252 is closed without openings, it is possible to completely block the sputtered liquid droplets from entering the fourth air duct 242, that is, to completely block the sputtered liquid from entering the air outlet channel. The third through hole 2531 is exposed in the cavity of the atomization cavity, so that the aerosol generated by the atomization carried by the external air can enter the fourth air guide tube 242 through the third through hole 2531 and the second through hole 2511, then flows to the air outlet hole 11 through the fourth air guide tube 242, the third through hole 2531 can be used as an air outlet of the atomization cavity, and the aerosol formed after the atomization can enter the air outlet channel through the air outlet.

The complete airflow path of the atomizer 100 is thus as follows: on the air intake channel, the external air firstly enters the atomizer 100 through the air intake hole 12, then enters the air intake pipe 15 through the first through hole 151 of the air intake pipe 15, enters the first air guide pipe 221 through the air intake pipe 15, pushes the silica gel valve plate 2311 to turn towards the third air guide pipe 241 and enter the third air guide pipe 241, and finally enters the atomization chamber through the third air guide pipe 241.

On the air outlet channel, after the external air enters the atomization chamber, aerosol generated by carrying atomization enters the second shielding member 25 through the third through hole 2531 of the second shielding member 25, enters the fourth air guide pipe 242 through the second through hole 2511 of the shielding member 25, then pushes the silica gel valve sheet 2321 to turn towards the direction of the second air guide pipe 222, meanwhile, the air flow enters the second air guide pipe 222, then enters the air outlet pipe 16 through the second air guide pipe 222, and finally flows to the air outlet hole 11 through the air outlet pipe 16. In conjunction with the intake passage described above, the complete airflow path of the atomizer 100 is shown by the path R1 in fig. 3.

The specific configuration of the first shielding member 23 is not limited to this, and may be other configurations in other embodiments of the present invention. For example, the first shielding member 23 may be a second shielding member 25, that is, the first shielding member 23 is also configured as a cylinder, but the cylinder is open at both ends and hollow, the inside of the cylinder is provided with the above-mentioned shielding silicone sheet, and then the first shielding member 23 is inserted into the first air duct 221 and the second air duct 222 by interference fit. At this time, the second shielding member 25 may also be inserted into the second air duct 222, so that the second bracket 24 may be omitted, and the liquid storage chamber 29 may be directly defined by the first bracket 24 and the second seal 26.

In addition, since the atomizing sheet 271 ultrasonically atomizes the liquid matrix 30, most of the sputtered droplets are concentrated in a range directly above the atomizing sheet 271, as shown in fig. 3, a concentrated sputtering route R2 of droplet sputtering. Therefore, the third air duct 241 and the fourth air duct 242 are distributed on two sides of the atomizing sheet 271, that is, the atomizing sheet 271 is located in the area between the third air duct 241 and the fourth air duct 242, that is, the air inlet and the air outlet of the atomizing chamber avoid the concentrated sputtering area of the liquid drops as much as possible, so that the sputtered liquid drops enter the third air duct 241 or the fourth air duct 242 as much as possible, and the sputtered liquid is reduced from entering the air inlet channel or the air outlet channel.

In this embodiment, in order to make contact between the electrical connection terminal of the power supply mechanism and the conductive spring 274 good when the electrical connection terminal is electrically connected, the conductive spring 274 is designed to be spiral, and a passage into which the electrical connection terminal of the power supply mechanism is inserted is formed therein. It will be readily appreciated that the conductive spring 274 may serve as a second conductive electrode of the ultrasonic atomizing assembly 27 for electrical connection to the other pole of the power mechanism.

Further, to prevent the liquid matrix 30 in the liquid reservoir 29 from leaking through the interior of the ultrasonic atomizing assembly 27 to the second electrode aperture 72 on the base 70, and from the second electrode aperture 72 out of the atomizer. Specifically, in order to prevent the liquid matrix 30 from entering the inside of the ultrasonic atomizing assembly 27 through the fitting gap between the atomizing plate 271 and the conductive upper cover 272, and from leaking out through the second electrode hole 72 in the base 70 further leaked through the fitting gap inside the ultrasonic atomizing assembly 27. The ultrasonic atomizing assembly 27 includes the flexible insulating member 273, the flexible insulating member 273 may be made of silica gel or rubber, as shown in fig. 10, the flexible insulating member 273 has an upper end surface abutting against the atomizing plate 271, and a lower end surface abutting against the resistor plate 275, the flexible insulating member 273 further has a through hole 2731 communicating with the upper end surface and the lower end surface, the upper end surface extends to form a rib 2732, the rib 2732 surrounds the through hole 2731 and is extruded by the atomizing plate 271, so as to seal the path of the liquid substrate 30 flowing to the through hole 2731, and prevent the liquid substrate 30 from flowing to the through hole 2731 along the upper end surface of the insulating flexible member 273, and then flowing to the second electrode hole 72 of the base 70.

The atomizer 200 includes an upper cover assembly 40, a liquid storage portion 50 and a base assembly 60, wherein the upper cover assembly 40 and the base assembly 60 are respectively mounted at two ends of the liquid storage portion 50, the liquid storage portion 50 is used for storing a liquid substrate 30 of the atomizer 200, the base assembly 60 is used for performing ultrasonic atomization on the liquid substrate 30 to generate aerosol for inhalation, the upper cover assembly 40 is used for discharging the aerosol generated by ultrasonic atomization out of the atomizer 200 for a user to inhale, and as in the first embodiment, the liquid substrate 30 in the first embodiment can also be smoke liquid or liquid medicine, so that the atomizer 200 in the first embodiment can also be used in the electronic cigarette or medical field.

The liquid storage portion 50 is a hollow cylinder structure with two open ends, the upper cover assembly 40 and the base assembly 60 are respectively mounted on the liquid storage portion 50 through the two open ends of the liquid storage portion 50, and when the upper cover assembly 40 and the bottom cover assembly 60 are mounted on the liquid storage portion 50, the upper cover assembly 40 and the bottom cover assembly 60 together define a liquid storage cavity 51 for storing liquid matrixes with the liquid storage portion 50. The liquid storage cavity 51 includes the first portion 511 and the second portion 512, as in the first embodiment, the inner diameter of the cavity of the second portion 512 along the radial direction of the atomizer 200 is smaller than the inner diameter of the cavity of the first portion 511 along the radial direction of the atomizer 200, so that after the atomizer 200 is used for a period of time, the residual liquid matrix 30 in the atomizer 200 can be concentrated in the second portion 512, and therefore, the ultrasonic atomization sheet of the atomizer 200 and the liquid level of the liquid matrix 30 can be maintained within a predetermined height range, and further, the ideal atomization effect can be maintained.

The bottom cover assembly 60 includes a base 61 and an ultrasonic atomizing assembly 62, the ultrasonic atomizing assembly 62 is identical to the ultrasonic atomizing assembly 27 of the embodiment, the base 61 is also provided with a first electrode hole 611 and a second electrode hole 612, the base 61 further defines a mounting chamber in which the ultrasonic atomizing assembly 62 is mounted, and the ultrasonic atomizing assembly 62 is mounted in the mounting chamber. The ultrasonic atomizing assembly 62 includes an ultrasonic atomizing plate 621, and when the bottom cover assembly 60 is mounted to the liquid reservoir 50, the ultrasonic atomizing plate 621 is directly exposed to the second portion 512 of the liquid reservoir 51, such that the ultrasonic atomizing plate 621 is immersed in the liquid reservoir 51, i.e., the ultrasonic atomizing plate 621 is directly in contact with the liquid matrix 30 of the liquid reservoir 51. Meanwhile, a portion of the first portion 511 is used to form an atomization chamber, that is, when the liquid substrate 30 is stored in the liquid storage chamber 51, the liquid surface of the liquid substrate 30 and the remaining portion of the first portion 511 of the liquid storage chamber 51 define an atomization chamber in which aerosol generated by atomization of the atomizer 200 is released.

It should be noted that, since the base 61 is a plastic part in the present embodiment, in order to prevent the liquid substrate 30 from leaking to the first electrode hole 611 of the base 61 through the assembly gap between the base 61 and the ultrasonic atomizing assembly 62, a groove is defined between the inner wall of the base 61 and the conductive lower cover 622 of the ultrasonic atomizing assembly 62, and a fourth sealing member 63 is installed in an interference manner in the groove to seal the assembly gap between the base 61 and the ultrasonic atomizing assembly 62.

With continued reference to fig. 13 and 14, fig. 13 and 14 respectively show a perspective view of the upper cover assembly 40 in one direction and an exploded view of the upper cover assembly 40 in one view, wherein the upper cover assembly 40 includes a suction nozzle 41, an air outlet pipe 42, an air inlet pipe 43, a first shielding member 44 and a second shielding member 45. The air outlet pipe 42 and the air inlet pipe 43 are fixedly arranged on the suction nozzle 41, and the air inlet pipe 43 is sleeved on the outer wall of the air outlet pipe 42; a second shielding member 45 is mounted at an end of the outlet duct 42, and a first shielding member 44 is mounted between the inlet duct 43 and the second shielding member 45.

The suction nozzle 41 is formed with an air inlet 411 for external air to enter the atomizer 200 and an air outlet 412 for aerosol to escape the atomizer 200, and a first sealing member (not shown) and a second sealing member (not shown) are provided between the suction nozzle 41 and the inner wall of the liquid storage portion 50 to seal the gap between the suction nozzle 41 and the inner wall of the liquid storage portion 50, preventing the liquid matrix in the liquid storage chamber 51 from leaking out of the gap.

The air outlet pipe 42 is of a hollow cylindrical structure and is provided with a fixed end and a free end which are opposite to each other, the fixed end is fixedly arranged on the cover 41, and the end face of the fixed end is arranged in an open way, so that the open part of the fixed end is in fluid communication with the air outlet hole 412 of the suction nozzle 41; the free end extends into the liquid storage chamber 51 along the length direction of the atomizer 200, the free end is provided with a blocking piece 421, and the blocking piece 421 is in sealing contact with the inner wall of the air outlet pipe 42, so that when the atomizer 200 is inverted, the liquid substrate 30 in the liquid storage chamber 51 is prevented from flowing into the air outlet pipe 42 from a gap between the blocking piece 421 and the inner wall of the air outlet pipe 42, and flows from the air outlet pipe 42 to the air outlet hole 412.

A fourth through hole 423 is formed in the side wall of the air outlet pipe 42 for enabling aerosol generated after atomization to enter the air outlet pipe 42. Further, in order to prevent the liquid matrix 30 of the liquid storage cavity 51 from entering the air outlet pipe 42 from the fourth through hole 423 when the atomizer 100 is inverted, a first ball 422 is provided in the air outlet pipe 42, the first ball 422 can roll reciprocally in the air outlet pipe 42 along the length direction of the air outlet pipe 42 under the action of gravity, and when the atomizer 200 is normally placed, the first ball 422 rolls to the free end of the air outlet pipe 42 and is limited by the blocking piece 421; in order to limit the first ball 422 when the atomizer 200 is inverted, the air outlet pipe 42 is formed with a limit portion 424, the limit portion 424 divides the air outlet pipe 42 into a first portion 425 and a second portion 426, the fourth through hole 423 is located in the second portion 426, the limit portion 424 is formed between the first portion 425 and the second portion 426 in a retracted shape, the pipe diameter of the first portion 425 is smaller than that of the second portion 426, and the first ball 422 is located in the second portion 426, so that the first ball 422 cannot roll into the first portion 425, and the limit portion 424 limits the first ball 422 to roll only in the second portion 426. When the atomizer 200 is inverted, the first ball 422 rolls from the free end of the air outlet pipe 42 to the fixed end under the action of gravity, and when the first ball rolls to the limiting part 424, the limiting part 424 limits the first ball 422 so that the first ball 422 cannot continue rolling.

The limiting portion 424 has an arc surface that is in spherical fit with the first ball 422, when the atomizer 200 is inverted, the first ball 422 rolls to the limiting portion 424 under the action of gravity and is in mutual fit with the arc surface of the limiting portion 424, so that the contact between the first ball 422 and the limiting portion 424 can be sealed, and fluid cannot enter the first portion 425 of the outlet pipe 42 through the contact, that is, fluid cannot enter the first portion 425 from the second portion 426 of the outlet pipe 42. Further, when the atomizer 200 is inverted, the liquid substrate 30 may enter the second portion 426 of the air outlet tube 42 through the fourth through hole 423 of the air outlet tube 42, but cannot flow into the first portion 425, and cannot flow to the air outlet 412, so that the liquid substrate 30 is effectively prevented from being sucked by a user. The end surface of the second portion 426 of the air outlet pipe 42 is provided with an air passing hole 4261 penetrating the second portion 426 along the axial direction of the air outlet pipe 42, the air passing hole 4261 is in fluid communication with the air inlet holes 411, one or two air passing holes 4261 can be provided, and one or two corresponding air inlet holes 411 can be provided.

The air inlet pipe 43 is in a hollow cylinder shape with two open ends, and the pipe diameter of the air inlet pipe 43 is larger than that of the air outlet pipe 42, so that the air inlet pipe 43 can be sleeved on the air outlet pipe 42, and a first air guide gap 431 is formed between the air outlet pipe 42 and the air outlet pipe 43. Specifically, the first air guide gap 431 is defined by an inner wall of the air inlet pipe 43 and an outer wall of the first portion 425 of the air outlet pipe 42, and the first air guide gap 431 is in fluid communication with the air passing hole 4261 and the air inlet hole 411, respectively.

With continued reference to fig. 15, fig. 15 shows a schematic cross-sectional view of the second shutter member 45 in one direction. The second shielding member 45 includes an upper cover 451 and a tubular body 452 fixedly connected to the upper cover 451. The upper baffle cap 451 includes a connecting portion 4511 fixedly connected to the free end of the air outlet duct 42, and a first baffle 4512 extending from the connecting portion 4511 toward the atomizing sheet 621. The tubular body 452 has an opening end facing the air inlet pipe 43 and a closed end 4521 facing the atomizing sheet, the opening end is in fluid communication with the first air guide gap 431 and further in fluid communication with the air inlet 411, an air inlet 4522 in fluid communication with the atomizing chamber is formed in the pipe wall of the tubular body 452, external air can enter the atomizing chamber through the air inlet 4522 via the air inlet channel, and the closed end is used for blocking sputtered droplets generated during ultrasonic atomization of the liquid matrix from being sputtered into the air inlet pipe 43 so as to prevent the sputtered droplets from blocking the air inlet channel and affecting the suction experience.

Further, the first barrier 4512 is configured in a pot cover shape such that the first barrier 4512 has an arc-shaped shielding surface toward the atomizing sheet 621. During ultrasonic atomization of the liquid matrix 30, the resulting sputtered droplets will splash against the arcuate mask surface, which will reflow the sputtered droplets to its surface to re-atomize the atomizer plate 621. It will be readily appreciated that the arcuate shielding surface has an area greater than the area of the atomizing sheet 621 such that the arcuate shielding surface can shield the concentrated sputtered areas of the liquid substrate 30 where the liquid droplets are ultrasonically sputtered, as indicated by the arrows on the liquid surface of the liquid substrate 30 in fig. 16.

Further, in order to prevent the sputtered droplets generated during ultrasonic atomization of the liquid matrix 30 from being sputtered perpendicularly to the arc-shaped shielding surface of the first baffle 4512, the droplets that are shielded by the arc-shaped shielding surface and rebound collide with the liquid that is sputtered to the arc-shaped shielding surface later, thereby influencing the atomization effect. The closed end 4521 of the tubular body 452 extends obliquely upwards towards the arc-shaped shielding surface to form a first inclined surface 4523, and the first inclined surface 4523 can well guide sputtered liquid drops to splash outwards to prevent the sputtered liquid drops from continuously vertically colliding with the first baffle 4512, so that the influence on atomization effect caused by collision between the liquid drops which are shielded by the arc-shaped shielding surface and rebound and liquid which continuously splashes upwards at the back can be prevented.

Further, to prevent sputtered droplets from blocking the rebounded droplets by the first baffle 4512 from entering the intake passage through the intake port 4522, the intake passage is blocked, affecting the pumping experience. The first baffle 4512 further extends in the direction of the atomizing plate 621 with a third baffle 4516, and the third baffle 4516 surrounds the air inlet 4522 to shield the air inlet 4522, so that sputtered droplets are prevented from blocking the rebounded droplets from entering the air inlet channel through the air inlet 4522 by the first baffle 4512. Further, with respect to the first inclined surface 4523, the tubular body 452 further extends obliquely downward in the direction of the arcuate shielding surface of the first baffle 4512 with a second inclined surface 4524, the second inclined surface 4524 is used for blocking the backflow of the guide flowing to the second inclined surface 4524 from the third baffle 4516 to the atomizing sheet 621, and at the same time, a second air guide gap 4515 is formed between the second inclined surface 4524 and the third baffle 4516, and the second air guide gap 4515 is communicated to the atomizing chamber. The reflow path of the sputtered droplets of the entire second shielding structure 45 is shown as path R2 in fig. 16.

Further, to prevent the liquid matrix 30 from flowing into the air inlet channel through the air inlet 4522 when the atomizer 200 is inverted, the liquid leakage occurs to the air inlet 411. The tubular body 452 is provided with a second ball 453 in the tube, the second ball 452 being capable of reciprocating rolling in the tube of the tubular body 452 under the force of gravity. Since the tubular body 452 is fixedly connected to the upper stopper 451, in order to prevent the second ball 453 from rolling into the upper stopper 451 when the atomizer 200 is inverted, the upper stopper 451 is provided with a stopper 4513, the stopper 4513 is provided with a through hole 45131, and external air can enter the hollow region of the connecting portion 4511 of the upper stopper 451 and then enter the pipe of the tubular body 452 through the through hole 45131. The blocking portion 4513 has an arc surface adapted to fit with the second ball 453, and when the atomizer 200 is caused, the second ball 453 rolls to the blocking portion 4513 and fits with the arc surface of the blocking portion 4513, thereby sealing a contact gap between the second ball 453 and the blocking portion 4513, and preventing leakage of the liquid substrate 30 to the air inlet holes 411 when the atomizer 200 is inverted.

Further, in order to enable the outside air to enter the atomizing chamber, the aerosol atomized in the atomizing chamber can be carried out to the air outlet 412. The upper cover assembly 40 further comprises a first shielding member 44, the first shielding member 44 is mounted between the air inlet pipe 43 and the second shielding member 45, the first shielding member 44 is a soft rubber piece such as silica gel or rubber, the first shielding member 44 is provided with a valve plate 441 which can be turned over under the action of air flow air pressure, a gap is formed after the valve plate 441 is turned over, air flow can enter the first shielding member 44 through the gap and enter the air outlet pipe 42 through a fourth through hole 423 of the air outlet pipe 42, so that the air flows to the air outlet 412, aerosol generated after atomization can be carried to the air outlet 412, and the gap formed after the valve plate 441 is turned over is the air outlet of the atomization chamber.

Since the first shielding member 44 is a silica gel piece, the first shielding member 44 has a certain elasticity, and when an air current exists, the valve plate 441 of the first shielding member 44 is turned over under the air pressure of the air current; when the air flow is eliminated, the valve plate 441 is restored to the initial position under the action of the elastic restoring force, and when the valve plate is restored to the initial position, a part of the liquid matrix 30 can be blocked from entering the air outlet pipe 42 through the first shielding member 44 when the atomizer 200 is inverted, and then escapes from the air outlet 412. Of course, in other embodiments of the present invention, instead of the first shielding member 44, a rigid material may be used, and an air inlet hole is required to be formed in the rigid material, so that air can enter the air outlet tube 42 through the air inlet hole, and the outside air can carry the aerosol generated by atomization to the air outlet 412, but when the atomizer 200 is inverted or swayed, the liquid substrate 30 also easily enters the air outlet tube 42 through the air inlet hole in the rigid material and is sucked by the user.

Thus, according to the above, when the user draws using the atomizer 200, the overall airflow path of the atomizer 200 is as follows on the intake passage: first, the external air enters the atomizer 200 through the air inlet 411, then enters the first air guide gap 431 between the air outlet pipe 42 and the air inlet pipe 43, then enters the air passing hole 4261 on the second portion 426 of the air outlet pipe 42 from the first air guide gap 431, then enters the hollow area of the connecting portion 4511 of the upper cover 451 from the air passing hole 4261, then enters the pipe of the tubular body 452 from the hollow area of the connecting portion 4511 of the upper cover 451 through the through hole 45131, and then enters the atomizing chamber through the air inlet 4522 on the pipe wall of the tubular body 452, thereby forming an air inlet passage.

On the air outlet channel, after the external air enters the atomizing chamber, the aerosol generated by atomizing the atomizing chamber flows to the first shielding member 44, and pushes the valve plate 441 of the first shielding member 44 to turn inwards to form an air inlet gap, the air flow enters the inside of the first shielding member 44 through the gap, enters the air outlet pipe 42 through the fourth through hole 423 of the air outlet pipe 42, and finally flows from the air outlet pipe 42 to the air outlet hole 412, as shown by the air flow path R1 in fig. 12.

The first ball 422 and the second ball 453 may be made of a material having a large density in the same volume, for example, the first ball 422 and the second ball 453 are steel balls. The greater the density, the greater the mass of the first ball 422 and the second ball 453, the heavier the first ball 422 and the second ball 453, and the closer the first ball 422 and the second ball 453 are attached to the cambered surface at the limit position, so that the sealing performance is better.

Further, to prevent the atomizer 200 from being horizontally placed or inverted, the liquid surface of the liquid substrate 30 floods the air inlet or the air outlet of the atomizing chamber, and enters the air inlet channel or the air outlet channel through the air inlet or the air outlet of the atomizing chamber, and then flows to the air inlet 411 or the air outlet 412 of the atomizer 200, thereby increasing the leakage probability of the liquid substrate 30. In this embodiment, the air inlet and the air outlet of the atomizing chamber are both disposed in the central region of the liquid storage chamber 51, so that when a fixed amount of the liquid substrate 30 is injected into the atomizer 200, the air inlet and the air outlet of the atomizer 200 can be made higher than the liquid level of the liquid substrate 30 in a normal use state, a horizontal or inverted state, thereby reducing the leakage probability of the liquid substrate 30, as shown in fig. 17 and 18.

It will be readily appreciated that the dimension of the reservoir 51 in the length direction is greater than the dimension of the reservoir 51 in the width direction, and this arrangement may be such that the level of the liquid matrix 30 is kept as low as possible when the atomizer 200 is placed laterally, so as to ensure that the level of the liquid matrix 30 does not flood the air inlet and outlet of the atomizing chamber when placed laterally. In order to make the outside air take away as much aerosol as possible after entering the atomizing chamber, the air inlet is arranged below the air outlet in this embodiment, that is, the distance between the air inlet and the liquid surface of the liquid matrix 30 is smaller than the distance between the air outlet and the liquid surface of the liquid matrix 30, so that the outside air can take away as much aerosol as possible after entering the atomizing chamber.

In order to enhance the atomization effect of ultrasonic atomization, the distance between the second shielding member and the liquid surface 30 of the liquid matrix in the above embodiment is not less than 30mm, and if the distance between the second shielding member and the liquid surface 30 of the liquid matrix is too close, the amount of smoke during ultrasonic atomization may be affected.

For example, the suction nozzle 10a may be moved from the first position to the second position by an external pressing force, or may be moved from the second position to the first position by an external pulling force. A stationary cover 30a is secured to the proximal end of the reservoir 20a for limiting the movement of the nozzle 10a from the second position to the first position to define the nozzle 10a in the first position. The suction nozzle 10a, the base 40a and the inner wall of the reservoir 20a together define a reservoir 21a forming an atomizer 100a, the reservoir 21a being adapted to store an atomized liquid matrix 50a. The base 40a is provided with an ultrasonic atomization assembly 41a, the ultrasonic atomization assembly 41a is directly immersed in the liquid storage cavity 21a, the ultrasonic atomization assembly 41a is used for carrying out ultrasonic atomization on the liquid matrix 50a to generate aerosol which can be sucked, and the base 40a is also provided with an air inlet hole 42a for external air to enter the atomizer 100 a.

Referring to fig. 22, the nozzle cover 11a includes an air outlet portion 111a and a connection portion 112a connected to the liquid storage portion 20a, wherein the air outlet portion 111a is provided with an air outlet hole 1111a for the aerosol generated after atomization to escape from the atomizer; the outer wall of the connection portion 112a is surrounded by a first seal 1121a and a second seal 1122a, and the first seal 1121a and the second seal 1122a are used to seal the assembly gap between the suction nozzle 10a and the liquid storage portion 20a, so as to prevent the liquid matrix 50a in the liquid storage chamber 21a from leaking out through the gap.

The air outlet pipe 12a has a tubular structure with two open ends, one end of which is connected with the connecting portion 112a of the nozzle cover 11a, and the other end of which extends in the liquid storage chamber 21a along the axial direction of the atomizer 100a and faces the ultrasonic atomizing assembly 41a. A baffle 121a is disposed in the tube of the air outlet tube 12a, and the baffle 121a divides the air outlet tube 12 into a first portion 122a and a second portion 123a along the axial direction, and the first portion 122a and the second portion 123a are hollow structures. The baffle 121a and the pipe wall of the second portion 123a define an atomization chamber 124a of the atomizer 200a, and the pipe wall of the first portion 122a is provided with a through hole 126a communicating with the atomization chamber 124a, so that atomized aerosol can enter the first portion 122a through the through hole 126 a. The first portion 122a is inserted into the air outlet hole 1111a of the air outlet portion 111a by interference fit, so that the entire air outlet tube 12a is fixedly connected to the mouthpiece cover 11a on the one hand, and aerosol entering the air outlet tube 12a is guided into the air outlet hole 1111a on the other hand, so that a user can inhale the aerosol at the mouthpiece 10 a.

With continued reference to fig. 21, fig. 21 is a schematic cross-sectional view of the nozzle 10a when connected to the reservoir 20a in the first position. When the suction nozzle 10a is located at the first position, a third air guide gap 22a is formed between the pipe wall of the air outlet pipe 12a and the inner wall of the liquid storage cavity 21a, the third air guide gap 22a is used as a part of an air flow channel between the air outlet hole 111a and the atomization chamber 124a, when the user sucks in the atomizer 100a, external air enters the atomization chamber 124a, and aerosol generated after atomization is carried into the pipe body of the first part 122a of the air outlet pipe 12a through the third air guide gap 22a and the through hole 126a of the air outlet pipe 12a, and then flows to the air outlet hole 1111a to be sucked by the user, so as to form an air outlet channel of the atomizer 100 a.

With continued reference to fig. 21, ambient air is introduced into the atomizing chamber 124a to entrain the atomized aerosol. The liquid storage portion 20a includes a first air inlet pipe 23a, a second air inlet pipe 24a, a third air inlet pipe 25a, and a flexible pipe 26a, where the first air inlet pipe 23a, the second air inlet pipe 24a, and the third air inlet pipe 25a are made of rigid materials, and the flexible pipe 26a may be made of soft rubber materials such as silica gel or rubber. The first air inlet pipe 23a is inserted into the air inlet hole 42a of the base 40a, two ends of the second air inlet pipe 24a are tightly sleeved on the first air inlet pipe 23a and the third air inlet pipe 25a, one end of the flexible pipe 26a is tightly sleeved on the third air inlet pipe 25a, and the other end of the flexible pipe extends into the atomization chamber 124a, so that external air enters the atomization chamber 124a through the air inlet hole 42a, the first air inlet pipe 23a, the second air inlet pipe 24a, the third air inlet pipe 25a and the flexible pipe 26a to form an air inlet channel of the atomizer 100a, and the air outlet channel is combined, so that the air flow channel of the whole atomizer 100a is shown by an arrow R1 route in fig. 3.

With continued reference to fig. 23, fig. 23 is a schematic cross-sectional view of the nozzle 10a when connected to the reservoir 20a in the second position. In the second position, the suction nozzle 10a and the liquid storage part 20a cooperate to seal the air inlet channel and the air outlet channel of the atomizer 100a, thereby sealing the liquid storage cavity 21a and preventing the external air from entering the liquid storage cavity 21a through the air inlet hole 42a and the air outlet hole 1111a, and the liquid substrate 50a is in contact with the external air for a long time to deteriorate; on the other hand, the liquid matrix 50a is prevented from leaking out through the air inlet channel or the air outlet channel when the atomizer 100a is placed laterally or upside down.

Specifically, the outlet tube 12a is further provided with a flexible member 127a surrounding the outer wall thereof, and the flexible member 127a may be silica gel or rubber. The inner wall of the liquid storage cavity 21a is formed with a pressing portion 27a for pressing the flexible member 127a, the pressing portion 27a is formed by shrinking inward from the inner wall of the liquid storage cavity 21a toward the center direction of the liquid storage cavity 21a, and further, a first limiting portion 28a is formed above the pressing portion 27a, and the first limiting portion 28a is used for limiting the suction nozzle at the second position. Therefore, when the suction nozzle moves from the first position to the second position under the action of the external pressing force, the lower end of the connecting portion 112a of the suction nozzle 10a abuts against the first limiting portion 28a, the suction nozzle 10a cannot continue to move towards the interior of the atomizer 100a under the limitation of the first limiting portion 28a, meanwhile, the extrusion portion 27a extrudes the flexible member 127a, and the flexible member 127a seals the third air guide gap 22a under the action of the extrusion force, so that the air flow channel between the atomizing chamber 124a and the air outlet 1111a, namely, the air outlet channel is sealed, and meanwhile, the suction nozzle 10a is kept at the second position under the damping action of the flexible member 127 a.

To facilitate the sealing of the air flow path, i.e., the air inlet path, between the air inlet aperture 42a and the atomizing chamber 124a when the mouthpiece 10a is in the second position. The other end of the flexible tube 26a is configured to extend into the atomizing chamber 124a in a curved shape, so that the flexible tube 26a will abut against the end wall of the atomizing chamber 124a under the deformation restoring force. When the suction nozzle 10a moves from the first position to the second position, the air outlet pipe 12a presses the flexible pipe 26a and makes the flexible pipe 26a continuously bend, so that the bending part of the flexible pipe 26a seals the pipeline of the flexible pipe 26a, thereby sealing the air flow channel between the air inlet hole 42a and the atomization chamber 124a, namely sealing the air inlet channel.

The ultrasonic mist assembly 41a is mounted on the base 40a, and the ultrasonic mist assembly 41a generally includes a mist plate 411a, the mist plate 411a being immersed in the liquid storage chamber 21a such that the mist plate 411 is in direct contact with the liquid substrate 50a, the mist plate 411a ultrasonically atomizing the liquid substrate 50a to generate an aerosol.

In combination with the above, the atomizer 100a operates as follows:

when the user needs to use the atomizer 100a to perform suction, the suction nozzle 10a is drawn to the first position, at this time, a third air guide gap 22a exists between the outer wall of the air outlet pipe 12a and the inner wall of the liquid storage cavity 2a1, the air outlet pipe 12a does not squeeze the flexible pipe 26a, at this time, an air flow channel (air inlet channel) between the air inlet hole 42a and the atomizing cavity 124a is conducted, an air flow channel (air outlet channel) between the air outlet hole 1111a and the atomizing cavity 124a is also conducted, the user performs suction at the air outlet hole 1111a, negative pressure is generated inside the atomizer 100a, external air enters the atomizing cavity 124a through the air inlet channel, meanwhile, aerosol generated by ultrasonic atomization of the liquid substrate 50a by the atomizing sheet 411a is released into the atomizing cavity 124a, and the external air carries the aerosol to the air outlet hole 1111a for the user to inhale.

When the user does not need to use the atomizer 100a, or when the atomizer 100a is in a storage state or a transport state, pressing the suction nozzle 10a from the first position to the second position, the flexible member 127a of the air outlet tube 12a of the suction nozzle 10a is pressed by the inner wall of the liquid storage chamber 21a to seal the third air guide gap 22a, so that the air flow passage (air outlet passage) between the air outlet hole 1111 and the atomizing chamber 124a is closed; simultaneously, the air outlet pipe 12a presses the flexible pipe 26a to continuously bend so as to seal the pipeline of the flexible pipe 26a, thereby closing the air flow channel (air inlet channel) between the air inlet hole 42a and the atomization cavity 124a, further preventing the atomizer 100a from sucking, and preventing the liquid matrix 50a from leaking out through the air inlet channel or the air outlet channel when the atomizer 100a is placed transversely or inverted.

It should be noted that in the above embodiment, the atomization effect of the atomizer is related to the power of the atomizing plate, the vibration frequency of the atomizing plate, and the liquid level of the liquid matrix 30 after the liquid matrix 30 is poured into the atomizer, the atomizing plate has an optimal liquid level range adapted to the atomizing plate in a certain power range, when the liquid level is in the range, the atomization effect is more desirable, and exceeds or falls below the range, and the atomization effect is undesirable, in the above embodiment, the power of the atomizing plate is preferably set to 10-12W, and the corresponding range of the liquid level is 5-25 mm. In addition, the atomizing sheet will generally have different vibration frequencies, and the thickness of the atomizing sheet is thinner as the vibration frequency is higher, the volume of the atomizing sheet body is smaller as the outer diameter size of the atomizing sheet is the same, and the power supported by the atomizing sheet is smaller, so that the different vibration frequencies also have the optimal liquid level height range suitable for the atomizing sheet, and in the embodiment, the vibration frequency range of the atomizing sheet is preferably set to be 2.4-3 Mhz, and the optimal liquid level height corresponding to the atomizing sheet is set to be 20-40 mm.

It should be noted that, the second shielding member 45 in the second embodiment may be connected to the end of the air inlet pipe 15 or the second shielding member 25 of the air outlet pipe 16 in the first embodiment, or the end of the air inlet pipe 15 and the end of the air outlet pipe 16 are simultaneously connected to the second shielding member 45, but at this time, the air inlet pipe 15 and the air outlet pipe 16 directly extend into the atomization chamber 291, that is, the suction nozzle 10 and the liquid storage portion 20 do not have the first installation position and the second installation position opposite to each other, the liquid storage portion 20 does not need to be provided with the first sealing element 21, and the second shielding member 45 is connected to the end of the air inlet pipe 15 and/or the end of the air outlet pipe 16, so that the second shielding member in the first embodiment can also realize the effect that the sputtered liquid drops flow back to the atomization sheet 271 under the action of the second shielding member to be atomized again.
