For example, when the suction nozzle 10 needs to be moved from the first mounting position to the second mounting position, the suction nozzle set 0 may be pressed with a force, and the suction nozzle 10 moves from the first mounting position to the second mounting position along the slide rail 13 under the pressing force, or the liquid storage part 20 may be pushed upward with a force, and the suction nozzle 10 may also move from the first mounting position to the second mounting position.
The housing of the mouthpiece 10 is further provided with an air inlet 12 and an air outlet 11, the air inlet 12 is used for providing an airflow inlet for the outside air to enter the atomizer 100, and the air outlet 11 is used for providing an airflow outlet for the aerosol generated after the ultrasonic atomization to escape from the atomizer 100. When the user uses atomizer 100 to aspirate in venthole 11 department, the inside negative pressure that produces of atomizer 100, outside air passes through inlet port 12 and gets into atomizer 100 to air current channel circulation to venthole 11 department between inlet port 12 and the venthole 11, and can carry the aerosol that produces after the ultrasonic atomization to flow to venthole 11 department together at the circulation in-process, thereby make the user inhale aerosol in venthole 11 department.
With reference to fig. 3, the nozzle 10 is further illustrated in a cross-sectional view in a second assembly position of the nozzle 10 and the reservoir 20, and also with reference to fig. 4, fig. 4 is a cross-sectional view of the nozzle 10 and the reservoir 20 in a first assembly position. An air inlet pipe 15 and an air outlet pipe 16 with two open ends are fixedly arranged inside the suction nozzle 10, a first through hole 151 is formed in the side wall of the air inlet pipe 15, 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 outside 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 air inlet pipe 15 and the air outlet pipe 16 are arranged obliquely as an extrusion component relative to the opening shape of one end of the liquid storage device 20, the oblique opening enables at least one part of the pipe body to be in a sharp shape so as to form an extrusion end 152 and an extrusion end 161, the extrusion end 152 and the extrusion end 161 are used for extruding the end sealing piece of the liquid storage portion 20 so as to enable at least one part of the air inlet pipe 15 and the air outlet pipe 16 to extend into the liquid storage portion 20, so that the external air can enter the liquid storage portion 20 through the air inlet pipe 15, and aerosol generated after ultrasonic atomization in the liquid storage portion 20 is carried into the air outlet pipe 16 and flows to the air outlet hole 11 through the air outlet pipe 16. When the suction nozzle 10 is connected with the liquid storage part 20 at the first assembly position, the air inlet pipe 15 and the air outlet pipe 16 do not extrude the sealing element at the end part of the liquid storage part 20, and the sealing elements at the end parts of the air inlet pipe 15 and the air outlet pipe 16 and the liquid storage part 20 are in an abutting state or keep a certain distance with the sealing element at the end part of the liquid storage part 20, as shown in fig. 4. When the mouthpiece 10 is connected to the reservoir 20 at the second assembly position, the air inlet tube 15 and the air outlet tube 16 squeeze the sealing member at the end of the reservoir 20 and pierce the sealing member at the end of the reservoir 20 and then enter the reservoir 20, as shown in fig. 3.
With reference to fig. 5, the liquid storage portion 20 is further illustrated in an exploded view in fig. 5, and also refer to fig. 3. The liquid storage part 20 comprises a first sealing member 21, a first bracket 22, a first shielding member 23, a second bracket 24, a second shielding member 25, a second sealing member 26, an ultrasonic atomization assembly 27 and a bottom cover 28. The first bracket 22 is fixedly connected with the bottom cover 28 to form a shell part of the liquid storage part 20; the second holder 24 and the second seal 26 are fixed in abutment with each other in the axial direction of the atomizer 100 inside the housing of the reservoir 20; the ultrasonic atomization assembly 27 is arranged at the bottom of the liquid storage part 20 and is used for carrying out ultrasonic vibration on the liquid substrate 30 to generate aerosol; the first shielding member 23 and the second shielding member 25 are used for preventing liquid drops sputtered by the liquid matrix 30 during ultrasonic atomization from entering the air inlet pipe 15 or the air outlet pipe 16; the first sealing member 21 is used to seal the end of the reservoir 20 and prevent leakage of the liquid matrix 30 in the reservoir chamber 29.
With respect to the first sealing member 21, please continue to refer to fig. 6, fig. 6 shows a perspective view of the first sealing member 21 in one direction, and also refer to fig. 3. The first sealing member 21 is made of a soft rubber material, such as rubber, silica gel, or a latex material, so that the first sealing member 21 can be connected with the first bracket 22 in an interference manner. The first seal 21 has a first seal hole 211 and a second seal hole 212 formed therein, and the first seal hole 211 and the second seal hole 212 are sealed with a weak silicone rubber. When the suction nozzle 10 is connected to the liquid storage portion 20 at the second assembly position, the pressing end 152 of the air inlet pipe 15 and the pressing end 161 of the air outlet pipe 16 respectively press the silica gel in the first sealing hole 211 and the second sealing hole 212 and pierce the silica gel in 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 through 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 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 punctured part will not be broken, thereby on one hand, preventing the broken silica gel from falling into the atomizer 100 and blocking the air inflow or outflow of the air flow; on the other hand, since the silicone rubber has elasticity, after the gas inlet pipe 15 or the gas outlet pipe 16 is separated from the first sealing hole 211 or the second sealing hole 212, the pressed portion can be restored to the original position by the elastic restoring force.
By the first sealing member 21, when the atomizer 100 is not needed to be used, the suction nozzle 10 and the liquid storage portion 20 are connected at the first assembly position, the silicone rubber of the first sealing hole 211 and the second sealing hole 212 is not punctured, and the liquid matrix 30 of the liquid storage cavity 29 is completely sealed in the liquid storage portion 20, so that the probability of leakage of the liquid matrix 30 when the atomizer 100 is not needed, such as 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, that is, the suction nozzle 10 is connected to the liquid storage portion 20 in the first assembly position, at this time, the air inlet pipe 15 and the air outlet pipe 16 do not pierce 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 liquid matrix 30 is prevented from being deteriorated by being contacted with the air for a long time.
The first bracket 22 is a hollow cylindrical body, and has a proximal end and a distal end opposite to each other, the proximal end is used for connecting with the suction nozzle 10, the distal end is used for connecting with the base 28, a first air duct 221 and a second air duct 222 extend from the end surface of the proximal end to the direction of the suction nozzle 10, and the first sealing member 21 is sleeved on the tube body surfaces of one ends of the first air duct 221 and the second air duct 222 in an interference manner. The first shielding member 23, the second bracket 24, the second shielding member 25, the second sealing member 26 and the ultrasonic atomization assembly 27 are arranged in the hollow part of the first bracket 22 through the distal opening of the first bracket 22. The first air duct 221 and the second air duct 222 are respectively arranged opposite to the first sealing hole 211 and the second sealing hole 212, when the suction nozzle 10 is connected with the liquid storage portion 20 at the second assembly position, the squeezing end 152 of the air inlet pipe 15 and the squeezing 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, and 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 duct 221 and the second air duct 222, so that the air inlet pipe 15 and the air outlet pipe 16 are respectively communicated with the first air duct 221 and the second air duct 222 through fluid.
The second holder 24 has a hollow structure, and one end thereof abuts against the first holder 22 and the other end thereof abuts against the second sealing member 26, so that the second holder 24 abuts between the first holder 22 and the second sealing member 26. A third air duct 241 and a fourth air duct 242 extend from one end of the second bracket 24 abutting against the first bracket 22 toward the bottom cover 28, 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. One end of the second holder 24, which abuts against the second seal member 26, is open so that at least a part of the second seal member 26 can be received in the hollow portion of the second holder 24 through the open end, thereby holding the second seal member 26.
The second sealing member 26 is also hollow and has an open end facing the second frame 24 and an open end facing the bottom cover 28, the open end facing the second frame 24 extends into the hollow region of the second frame 24, the open end facing the bottom cover 28 is used for accommodating the ultrasonic atomization assembly 27, so as to hold the ultrasonic atomization assembly 27 in the hollow region of the second sealing member 26, and further to enable the second sealing member 26 to be communicated with the hollow region of the second frame 24, the hollow region is used as a liquid storage chamber 29 of the atomizer 100, and the liquid storage chamber 29 is used for storing a liquid matrix 30. Since the reservoir 29 is defined by the hollow regions of the first holder 24 and the second sealing member 26, the reservoir 29 is divided into a first portion 291 and a second portion 292, the first portion 291 is formed by the hollow region of the second holder 24, and the second portion 292 is formed by the hollow region of the second sealing member 26. The second sealing member 26 is made of a soft plastic material, such as rubber, silica gel, or latex, and the first sealing member 26 is assembled inside the housing of the liquid storage 20 in an interference manner, so as to prevent the liquid matrix 30 in the liquid storage cavity 29 from leaking out of the atomizer 100 through an assembly gap between the first bracket 22 and the bottom cover 28. Meanwhile, one part of the first portion 291 is used as an atomization chamber of the atomizer 100 to provide a space for releasing aerosol generated by ultrasonic atomization, and the atomization chamber is respectively in fluid communication with the third air duct 241 and the fourth air duct 242, so that outside air can enter the atomization chamber through the air inlet pipe 15, the first air duct 221 and the third air duct 241 to form an air inlet channel, and then the atomized aerosol is carried to flow to the air outlet 12 through the fourth air duct 242 and the second air duct 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 the outside air enters the atomization chamber through the third air duct 241; and fourth air duct 242 can regard as the gas outlet of atomizing chamber, and outside air carries the aerosol to enter into air outlet channel through fourth air duct 242 after entering atomizing chamber.
Because the second sealing member 26 is made of soft rubber, the ultrasonic atomization assembly 27 can be tightly fitted in the hollow area of the first sealing member 26 in an interference manner, so that the ultrasonic atomization assembly 27 is directly immersed in the liquid storage cavity 29. The ultrasonic atomizing assembly 27 generally comprises 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 also immersed in the liquid storage chamber 29, that is, the atomizing plate 271 is directly contacted with the liquid matrix 30. When the ultrasonic atomizing assembly 27 is powered on, the atomizing plate 271 generates high frequency resonance and makes the surface of the liquid substrate 30 swell, and cavitation occurs around the liquid surface of the swell, so that the liquid substrate 30 is atomized into small-molecule aerosol, that is, the liquid substrate 30 is atomized into aerosol, and the generated aerosol is released into the atomizing chamber.
When a user needs to use the atomizer 100, the atomizer 100 is started, the ultrasonic atomization assembly 27 is powered on, the atomization sheet 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 the inside of the atomizer 100 to generate negative pressure, outside 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 and escapes from the atomizer 100 to be inhaled by the user.
It should be noted that, because the ultrasonic atomizing assembly 27 is directly immersed in the liquid storage chamber 29, and the atomizing plate 271 directly contacts with the liquid substrate 30, in order to maintain a relatively ideal atomizing effect, a preset height range is usually required to be maintained between the liquid surface of the liquid substrate 30 and the atomizing plate 271, the preset height range is related to the selection of the atomizing plate 271, for example, the preset liquid surface heights are different if the oscillation frequencies of the atomizing plate 271 are different, and a manufacturer can set the liquid surface height range according to the specific atomizing plate 271 selected.
Further, in order to maintain the liquid level of the atomizing plate 271 and the liquid matrix 30 within a predetermined height range after the atomizer 100 is used for a period of time, in the present embodiment, the hollow area of the second sealing member 26 is used as the second portion 292 of the liquid storage cavity 29, and the second portion 292 is retracted compared to the first portion 291 of the liquid storage cavity 29, 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 period of time, the liquid matrix 30 in the liquid storage cavity 29 is consumed too much, the remaining liquid matrix 30 is concentrated in the second portion 292 of the liquid storage cavity 29, and the radial size of the cavity of the second portion 292 is smaller, the liquid matrix 30 is concentrated in the second portion 292, and accordingly has a certain height, so that the liquid level of the atomizing plate 271 and the remaining liquid matrix 30 can still be maintained within the predetermined height range.
It should be noted that, since the atomizing plate 271 of the present embodiment is directly immersed in the reservoir chamber 29, the atomizing plate 271 directly contacts the liquid substrate 30, and the liquid substrate 30 in the reservoir chamber 29 is not guided to the atomizing plate 271 by an oil guide (not shown) to be atomized, the liquid substrate 30 in the present embodiment is atomized by the high-frequency vibration generated by the atomizing plate 271, and at the same time, a part of the liquid substrate 30 is splashed toward the third air duct 241 and the fourth air duct 242 due to the high-frequency vibration. Because the third air duct 241 and the fourth air duct 242 are respectively communicated 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, the liquid matrix 30 can be leaked when the liquid flows to the air inlet hole 12, the liquid can be inhaled by a user when the liquid flows 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 used to block the droplets splashed by the ultrasonic atomization from splashing into the air inlet channel, and also to prevent the liquid substrate 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, and referring to fig. 3 in combination, fig. 7 shows a 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 contact with the first bracket 22 and the second bracket 24 to seal the assembly gap between the first bracket 22 and the second bracket 24, so as to prevent the airflow from escaping from the assembly gap between the first bracket 22 and the second bracket 24, thereby maintaining the air tightness inside the atomizer 100.
The first shielding member 23 further includes a silicone valve plate 2311 disposed at the first insertion hole 231, thereby providing shielding on the air intake passage to prevent splashed liquid droplets generated during ultrasonic atomization or the liquid substrate 30 from leaking from the air intake hole 12 through the third air duct 241 when the atomizer 100 is inverted; and a silica gel valve plate 2321 disposed at the second insertion hole 232, thereby providing shielding on the air outlet channel to prevent splashed liquid droplets generated during ultrasonic atomization or liquid matrix 30 inverted by the atomizer 100 from leaking from the air outlet 11 through the fourth air duct 242.
Further, a plurality of silica gel valve plates 2311 and silica gel valve plates 2321 are respectively arranged in the first inserting hole 231 and the second inserting hole 232, the plurality of silica gel valve plates 2311 and silica gel valve plates 2321 are uniformly distributed in the first inserting hole 231 and the second inserting hole 232, a gap 233 is kept between any two silica gel valve plates, and it is easy to understand that the gap 233 is very small so as to fully prevent the sputtered liquid drops or the liquid matrix 30 from passing through the gap 233. The gap 233 is arranged to enable the air flow to enter the air inlet channel or the air outlet channel, each silica gel valve plate 2311 can independently turn towards the third air guide pipe 241 under the air pressure of the air flow, a gap is formed after the silica gel valve plates 2311 turn, so that the outside air can conveniently enter the third air guide pipe 241 through the gap through the first air guide pipe 221 and then flow into the atomization chamber, the gap can be used as an air inlet through which the outside air enters the atomization chamber, and the outside air can enter the atomization chamber through the air inlet channel; and silica gel valve block 2321 can be independent at the atmospheric pressure effect of air current the direction upset towards second air duct 222, also can form a breach after silica gel valve block 2321 upset to the aerosol after being convenient for carry the atomizing enters into second air duct 222 through this breach through fourth air duct 242, and then stays 11 departments of venthole. It is easy to understand that, since the first silicone shielding sheet 2311 and the second silicone shielding sheet 2321 are both soft rubber members, after the air pressure of the air flow disappears, the first silicone shielding sheet 2311 and the second silicone shielding sheet 2321 will recover to the original positions under 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 the gap 233 exists between the silicon rubber valve plates, although the size of the gap 233 is very small, a small part of the sputtered liquid drops still flow to the air outlet 11 through the gap 233. Therefore, the atomizer 100 further includes a second shielding member 25, and the second shielding member 25 further functions to block entry of the splashed liquid into the gas outlet passage. As shown in fig. 8 and 9, fig. 8 and 9 are perspective views of the second shutter member 25 in two directions.
Specifically, the second shielding member 25 is configured to be a tubular body, and the second shielding member 25 is made of a soft rubber such as rubber or silicone, and has an open end 251 and a closed end 252 opposite to each other, and a sidewall 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 gas guiding tube 242 by interference fit, and seals the gap between the inner wall of the fourth gas guiding tube 242 and the outer wall of the second shielding member 25, and since the end face of the shielding end 252 is closed and has no opening, the liquid drops sputtered can be completely prevented from entering the fourth gas guiding tube 242, that is, the liquid sputtered can be completely prevented from entering the gas outlet channel. And third through-hole 2531 exposes in the atomizing chamber, therefore the outside air carries the aerosol that the atomizing produced accessible third through-hole 2531, second through-hole 2511 and enters into fourth air duct 242, and rethread fourth air duct 242 flows to venthole 11 department, and third through-hole 2531 can regard as the gas outlet of atomizing chamber, and the aerosol that forms after the atomizing can get into air outlet channel through this gas outlet.
The complete airflow path of the nebulizer 100 is thus as follows: on the air inlet channel, the outside air firstly enters the atomizer 100 through the air inlet hole 12, enters the air inlet pipe 15 through the first through hole 151 of the air inlet pipe 15, enters the first air duct 221 through the air inlet pipe 15, pushes the silica gel valve plate 2311 to turn over towards the third air duct 241 so as to enter the third air duct 241, and finally enters the atomization chamber through the third air duct 241.
On the air outlet channel, after the outside air enters the atomizing chamber, the aerosol generated by carrying the atomization enters the second shielding member 25 through the third through hole 2531 of the second shielding member 25, enters the fourth air duct 242 through the second through hole 2511 of the second shielding member 25, then pushes the silica gel valve block 2321 to turn towards the second air duct 222, meanwhile, the air flow enters the second air duct 222, then enters the air outlet pipe 16 through the second air duct 222, and finally flows to the air outlet hole 11 through the air outlet pipe 16. In conjunction with the air inlet passage described above, the complete air flow path of the atomizer 100 is shown as path R1 in fig. 3.
In the description of the present invention, the specific structure of the first shutter member 23 is not limited to this, and other structures may be adopted in other embodiments of the present invention. For example, the first shielding member 23 may be the second shielding member 25, that is, the first shielding member 23 is also provided in the shape of a cylinder, but the cylinder is hollow with two open ends, the above-mentioned silicone shielding sheet is provided inside the cylinder, 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 reservoir chamber 29 is defined by the first bracket 24 and the second sealing member 26.
In addition, when the atomizing plate 271 atomizes the liquid substrate 30 ultrasonically, most of the sputtered droplets are concentrated in the range directly above the atomizing plate 271, as shown in fig. 3 by the 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 atomization plate 271, that is, the atomization plate 271 is located in the region between the third air duct 241 and the fourth air duct 242, that is, the air inlet and the air outlet of the atomization chamber avoid the concentrated splashing region of the liquid droplets as much as possible, so that the splashing liquid droplets are reduced as much as possible to enter the third air duct 241 or the fourth air duct 242, and the splashing liquid is reduced to enter the air inlet channel or the air outlet channel.

The air outlet pipe 42 and the air inlet pipe 43 are both 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; the second shutter member 45 is installed at an end of the outlet duct 42, and the first shutter member 44 is installed between the inlet duct 43 and the second shutter member 45.
The suction nozzle 41 is formed with an air inlet 411 through which the external air enters the atomizer 200 and an air outlet 412 through which the aerosol escapes from 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 part 50 to seal a gap between the suction nozzle 41 and the inner wall of the liquid storage part 50 and prevent the liquid medium in the liquid storage chamber 51 from leaking out of the gap.
The air outlet pipe 42 is substantially a hollow cylinder structure and has a fixed end and a free end opposite to each other, the fixed end is fixedly installed on the cover 41, and the end surface of the fixed end is open, so that the opening of the fixed end is in fluid communication with the air outlet 412 of the suction nozzle 41; the free end extends into the liquid storage cavity 51 along the length direction of the atomizer 200, the blocking piece 421 is arranged at the free end, 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 matrix 30 in the liquid storage cavity 51 flows 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 to the air outlet hole 412 from the air outlet pipe 42.
The sidewall of the outlet tube 42 is provided with a fourth through hole 423 for the aerosol generated after atomization to enter the outlet tube 42. Further, in order to prevent the liquid substrate 30 in the liquid storage cavity 51 from entering the air outlet pipe 42 from the fourth through hole 423 when the atomizer 100 is inverted, the first ball 422 is arranged inside the air outlet pipe 42, the first ball 422 can roll back and forth inside 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 balls 422 when the atomizer 200 is inverted, the outlet tube 42 is formed with a limiting portion 424, the limiting portion 424 divides the outlet tube 42 into a first part 425 and a second part 426, the fourth through hole 423 is located in the second part 426, the limiting portion 424 is formed between the first part 425 and the second part 426 in a retracted shape, the tube diameter of the first part 425 is smaller than that of the second part 426, the first balls 422 are located in the second part 426, so that the first balls 422 cannot roll into the first part 425, and the limiting portion 424 limits the first balls 422 to roll only in the second part 426. When the atomizer 200 is inverted, the first ball 422 rolls from the free end of the air outlet tube 42 toward the fixed end under the action of gravity, and when the atomizer rolls to the limiting portion 424, the limiting portion 424 limits the first ball 422 so that the first ball 422 cannot roll continuously.
The limiting part 424 has an arc surface in spherical fit with the first ball 422, when the atomizer 200 is inverted, the first ball 422 rolls to the limiting part 424 under the action of gravity, and fits with the arc surface of the limiting part 424, so that the contact position of the first ball 422 and the limiting part 424 can be sealed, fluid cannot enter the first part 425 of the air outlet pipe 42 through the contact position, that is, fluid cannot enter the first part 425 from the second part 426 of the air 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, i.e., cannot flow to the air outlet 412, thereby effectively preventing the user from sucking the liquid substrate 30. The end surface of the second part 426 of the air outlet pipe 42 is provided with air passing holes 4261 which penetrate through the second part 426 along the axial direction of the air outlet pipe 42, the air passing holes 4261 are 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 are also 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 is 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 guiding gap 431 is defined by the inner wall of the inlet pipe 43 and the outer wall of the first portion 425 of the outlet pipe 42, and the first air guiding gap 431 is respectively communicated with the air passing hole 4261 and the air inlet hole 411 in a fluid mode.
Continuing to refer to fig. 15, fig. 15 shows a cross-sectional view of the second shielding member 45 in one direction. The second shielding member 45 includes an upper shield cap 451 and a tubular body 452 fixedly connected to the upper shield cap 451. The upper blocking cover 451 includes a connecting portion 4511 fixedly connected to the free end of the air outlet pipe 42 and a first blocking plate 4512 extending from the connecting portion 4511 toward the atomizing sheet 621. The tubular body 452 is provided with an open end facing the air inlet pipe 43 and a closed end 4521 facing the atomizing sheet, the open end is in fluid communication with the first air guide gap 431 and is further in fluid communication with the air inlet hole 411, an air inlet 4522 in fluid communication with the atomizing chamber is formed in the pipe wall of the tubular body 452, the outside air can enter the atomizing chamber through the air inlet 4522 via the air inlet channel, and the closed end is used for preventing splashed liquid drops generated during ultrasonic atomization of the liquid matrix from splashing into the air inlet pipe 43 so as to prevent the splashed liquid drops from blocking the air inlet channel and influencing suction experience.
Further, the first blocking plate 4512 is configured in a pan cover shape, so that the first blocking plate 4512 has an arc-shaped blocking surface facing the atomizing plate 621. Upon ultrasonic atomization of the liquid substrate 30, the resulting splashed droplets will be splashed toward the arc-shaped shielding surface, which will reflow the droplets splashed onto its surface, so that the atomizing plate 621 re-atomizes. It will be readily appreciated that the area of the arcuate shielding surface is greater than the area of the atomization sheet 621, so that the arcuate shielding surface can shield the focused splash zone of the ultrasonically sputtered droplets of liquid substrate 30, as indicated by the arrows on the surface of the liquid substrate 30 in FIG. 16.
Further, in order to prevent the splashed liquid droplets generated during the ultrasonic atomization of the liquid matrix 30 from vertically splashing the arc-shaped shielding surface of the first shielding plate 4512, the liquid droplets rebounded after being shielded by the arc-shaped shielding surface collide with the liquid continuously splashing to the arc-shaped shielding surface, thereby affecting the atomization effect. The closed end 4521 of the tubular body 452 extends obliquely upward to form a first inclined surface 4523 toward the arc-shaped shielding surface, the first inclined surface 4523 can well guide the sputtered liquid droplets to sputter toward the outside, and the sputtered liquid droplets are prevented from continuously colliding with the first baffle 4512 vertically, so that the liquid droplets rebounded after being shielded by the arc-shaped shielding surface can be prevented from colliding with the liquid continuously sputtered upward to affect the atomization effect.
Further, to prevent sputtered droplets from being blocked by the first shutter 4512 and rebounded droplets from entering the intake passage through the intake port 4522, the intake passage may be blocked, which may affect the pumping experience. The first blocking plate 4512 further extends a third blocking plate 4516 towards the atomizing plate 621, and the third blocking plate 4516 surrounds the air inlet 4522 to block the air inlet 4522, so that sputtered droplets are prevented from being blocked by the first blocking plate 4512 and rebounded droplets enter the air inlet channel through the air inlet 4522. Further, relative to the first inclined surface 4523, the tubular body 452 extends obliquely downward in a direction of the arc-shaped shielding surface of the first shielding plate 4512 with a second inclined surface 4524, the second inclined surface 4524 is used for blocking the third shielding plate 4516 from flowing to the second inclined surface 4524 and guiding the backflow to the atomizing sheet 621, and meanwhile, a second air guide gap 4515 is formed between the second inclined surface 4524 and the third shielding plate 4516, and the second air guide gap 4515 is communicated with the atomizing chamber. The return route of the sputtered droplets of the entire second shielding structure 45 is shown as route R2 in fig. 16.
Further, to prevent the liquid medium 30 from flowing into the air inlet channel through the air inlet 4522 when the atomizer 200 is inverted, and then flowing to the air inlet 411 to cause liquid leakage. A second ball 453 is disposed within the tubular body 452 and the second ball 452 is capable of rolling back and forth within the tubular body 452 under the force of gravity. Since the tubular body 452 is fixedly connected to the upper blocking cover 451, in order to prevent the second ball 453 from rolling into the upper blocking cover 451 when the atomizer 200 is inverted, the upper blocking cover 451 is provided with a resisting portion 4513, the resisting portion 4513 is provided with a through hole 45131, and after the outside air enters the hollow region of the connecting portion 4511 of the upper blocking cover 451, the outside air can enter the pipe of the tubular body 452 through the through hole 45131. The resisting portion 4513 has an arc surface fitting with the second ball 453, and when the atomizer 200 is caused, the second ball 453 rolls to the resisting portion 4513 and fits with the arc surface of the resisting portion 4513, so as to seal a contact gap between the second ball 453 and the resisting portion 4513, and prevent the liquid matrix 30 from flowing to the air inlet 411 and leaking when the atomizer 200 is inverted.
Further, in order to make the outside air enter the atomizing chamber, the aerosol generated by atomizing in the atomizing chamber can be carried out to the air outlet 412. The upper cover assembly 40 further includes a first shielding member 44, the first shielding member 44 is installed between the air inlet pipe 43 and the second shielding member 45, the first shielding member 44 is made of soft rubber such as silica gel or rubber, the first shielding member 44 is formed with a valve plate 441 capable of being turned under the action of air pressure of the air flow, a gap is formed after the valve plate 441 is turned, the 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, and then flows to the air outlet 412, so that the aerosol generated after atomization can be carried to the air outlet 412, and it is easy to understand that the gap formed after the valve plate 441 is turned is the air outlet of the atomization chamber.
Since the first shielding member 44 is a silicone member, the first shielding member 44 has certain elasticity, and when there is an air flow, the valve sheet 441 of the first shielding member 44 is turned over under the air pressure of the air flow; when the air flow disappears, the valve plate 441 returns to the initial position under the action of the elastic restoring force, and when the atomizer 200 returns to the initial position, a part of the liquid substrate 30 is blocked from entering the air outlet pipe 42 through the first blocking member 44 and then escaping from the air outlet 412 when the atomizer is inverted. Of course, in other embodiments of the present invention, a rigid material may be used to replace the first shielding member 44, and at this time, an air inlet hole needs to be formed in the rigid material, so that the air flow can enter the air outlet pipe 42 through the air inlet hole, and the aerosol generated by atomization can be carried to the air outlet 412 by the external air, but when the atomizer 200 is inverted or shaken, the liquid matrix 30 can easily enter the air outlet pipe 42 through the air inlet hole formed in the rigid material to be inhaled by the user.
Thus, according to the above, when a user uses the nebulizer 200 for inhalation, the overall airflow path of the nebulizer 200 is as follows, on the intake channel: the external air firstly 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 part 426 of the air outlet pipe 42 from the first air guide gap 431, then enters the hollow area of the connecting part 4511 of the upper block cover 451 from the air passing hole 4261, then enters the pipe of the tubular body 452 through the through hole 45131 from the hollow area of the connecting part 4511 of the upper block cover 451, and then enters the atomizing chamber through the air inlet 4522 on the pipe wall of the tubular body 452, so as to form an air inlet passage.
After the outside air enters the atomizing chamber, the aerosol generated by the atomization of the atomizing chamber flows to the first shielding member 44, and pushes the valve plate 441 of the first shielding member 44 to turn inward to form an air inlet gap, through which the air flow enters the inside of the first shielding member 44, enters the air outlet pipe 42 through the fourth through hole 423 of the air outlet pipe 42, and finally flows to the air outlet 412 from the air outlet pipe 42, as shown in 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 larger density in the same volume, for example, the first ball 422 and the second ball 453 may be steel balls. The larger the density is, the larger the mass of the first ball 422 and the second ball 453 is, the heavier the first ball 422 and the second ball 453 are, the closer the fit with the arc surface at the limit position is, and the sealing performance is better.
Further, in order to prevent the liquid surface of the liquid substrate 30 from submerging the air inlet or the air outlet of the atomization chamber when the atomizer 200 is horizontally placed or inverted, the liquid substrate enters the air inlet channel or the air outlet channel through the air inlet or the air outlet of the atomization chamber and then flows out of the air inlet hole 411 or the air outlet hole 412 of the atomizer 200, and therefore the probability of leakage of the liquid substrate 30 is increased. In this embodiment, the air inlet and the air outlet of the atomizing chamber are both disposed in the central region of the reservoir 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 can be both higher than the liquid surface of the liquid substrate 30 when the atomizer 200 is in a normal use state, horizontal or upside down, thereby reducing the probability of leakage 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 ensure that the liquid level of the liquid matrix 30 is kept as low as possible when the atomizer 200 is laterally positioned, so as to ensure that the liquid level of the liquid matrix 30 does not flood the air inlet and the air outlet of the atomization chamber when laterally positioned. In order to take away as much aerosol as possible after the external air enters the atomizing chamber, the air inlet is disposed below the air outlet, that is, the distance between the air inlet and the liquid surface of the liquid substrate 30 is smaller than the distance between the air outlet and the liquid surface of the liquid substrate 30, so that the external air can take away as much aerosol as possible after the external air enters the atomizing chamber.
It should be noted that, in order to improve the atomization effect of the 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 the smoke generated during the ultrasonic atomization will be affected.

With continued reference to FIG. 21, FIG. 21 is a cross-sectional view of the suction nozzle 10a being 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 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 atomizing chamber 124a, when a user uses the atomizer 100a for suction, outside air enters the atomizing chamber 124a, carries aerosol generated after atomization, enters 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 flows to the air outlet hole 1111a to be sucked by the user, so that the air outlet channel of the atomizer 100a is formed.
With continued reference to fig. 21, ambient air is introduced into the nebulizing chamber 124a to entrain the nebulized aerosol. The liquid storage part 20a comprises a first air inlet pipe 23a, a second air inlet pipe 24a, a third air inlet pipe 25a and a flexible pipe 26a, wherein the first air inlet pipe 23a, the second air inlet pipe 24a and the third air inlet pipe 25a are all made of rigid materials, and the flexible pipe 26a can 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 atomizing chamber 124a, so that the outside air enters the atomizing 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 with the air inlet channel, so that the air flow channel of the whole atomizer 100a is shown as the arrow route R1 in fig. 3.
With continued reference to FIG. 23, FIG. 23 illustrates a cross-sectional view of the suction nozzle 10a in a second position in connection with the reservoir 20 a. 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, so as to seal the liquid storage cavity 21a, prevent the outside air from entering the liquid storage cavity 21a through the air inlet hole 42a and the air outlet hole 1111a, and prevent the liquid substrate 50a from being deteriorated after being contacted with the outside air for a long time; on the other hand, the liquid medium 50a is prevented from leaking out through the inlet or outlet passages when the atomizer 100a is laterally placed or inverted.
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 silicone rubber or rubber. The inner wall of the liquid storage cavity 21a is provided with a pressing part 27a for pressing the flexible piece 127a, the pressing part 27a is formed by inwards shrinking from the inner wall of the liquid storage cavity 21a towards the center direction of the liquid storage cavity 21a, a first limiting part 28a is further formed above the pressing part 27a, and the first limiting part 28a is used for limiting the suction nozzle at the second position. Therefore, when the suction nozzle 10a moves from the first position to the second position under the action of an 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 move further into the atomizer 100a under the limitation of the first limiting portion 28a, the squeezing portion 27a squeezes the flexible piece 127a, and the flexible piece 127a seals the third air guide gap 22a under the action of the squeezing force, so as to seal the air flow channel between the atomizing chamber 124a and the air outlet hole 1111a, i.e., seal the air outlet channel, and meanwhile, the suction nozzle 10a is kept at the second position under the damping action of the flexible piece 127 a.
To facilitate the air flow path between the air inlet aperture 42a and the atomization chamber 124a when the mouthpiece 10a is in the second position, i.e., the air inlet path, is sealed. The other end of the flexible tube 26a is configured to extend into the atomization chamber 124a in a curved shape, so that the flexible tube 26a abuts against the end wall of the atomization chamber 124a under the deformation restoring force. When the mouthpiece 10a moves from the first position to the second position, the air outlet pipe 12a will press the flexible pipe 26a and make the flexible pipe 26a bend continuously, so that the bend of the flexible pipe 26a seals the pipe of the flexible pipe 26a, thereby sealing the air flow channel between the air inlet hole 42a and the atomizing chamber 124a, i.e. sealing the air inlet channel.
The base 40a is provided with an ultrasonic atomization assembly 41a, the ultrasonic atomization assembly 41a generally comprises an atomization sheet 411a, the atomization sheet 411a is soaked in the liquid storage cavity 21a, so that the atomization sheet 411 is directly contacted with the liquid substrate 50a, and the atomization sheet 411a carries out ultrasonic atomization on the liquid substrate 50a to generate aerosol.
In conjunction with the above, the operating principle of the atomizer 100a is as follows:

When the user does not need to use the atomizer 100a, or when the atomizer 100a is in the storage state or the transportation state, the suction nozzle 10a is pressed from the first position to the second position, the flexible piece 127a of the air outlet pipe 12a of the suction nozzle 10a is pressed by the inner wall of the liquid storage cavity 21a to seal the third air guide gap 22a, so that the air flow channel (air outlet channel) between the air outlet hole 1111 and the atomizing chamber 124a is closed; meanwhile, the air outlet pipe 12a presses the flexible pipe 26a to continuously bend to seal the pipeline of the flexible pipe 26a, so as to close the air flow channel (air inlet channel) between the air inlet hole 42a and the atomizing chamber 124a, thereby 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 upside down.
