The suction nozzle 10 has a first position and a second position relative to the liquid storage part 20, that is, the suction nozzle 10 can be in the first position and the second position. The second position is connected with the liquid storage part 20 . For example, the suction nozzle 10 can move from the first position to the second position under the action of external pressing force, and can also move from the second position to the first position under the action of external pulling force. The fixed cover 30 is fixed on the proximal end of the liquid storage part 20, and is used for limiting the suction nozzle 10 when the suction nozzle 10 moves from the second position to the first position, so as to limit the suction nozzle 10 to the first position. The suction nozzle 10 , the base 40 and the inner wall of the liquid storage part 20 jointly define a liquid storage cavity 21 of the atomizer 100 , and the liquid storage cavity 21 is used for storing the atomized liquid matrix 50 .

The ultrasonic atomization assembly 40 is used to ultrasonically atomize the liquid matrix to produce an inhalable aerosol. The base 40 also An air inlet 42 is provided for the outside air to enter the atomizer 100 . It should be noted that the liquid base 50 can be smoke liquid or medical liquid, so the atomizer 100 provided by the embodiment of the present utility model can be used in electronic cigarette or medical field.

For the above-mentioned suction nozzle 10, please continue to refer to FIG. 4, which shows a schematic diagram of the classification of the suction nozzle 10 at a viewing angle. At the same time, referring to FIG. Trachea12. The nozzle cover 11 includes an air outlet part 111 and a connection part 112 connected with the liquid storage part 20. The air outlet part 111 is provided with an air outlet hole 1111 for the aerosol generated after atomization to escape the atomizer; the outer wall of the connection part 112 Surrounded by a first sealing member 1121 and a second sealing member 1122, the first sealing member 1121 and the second sealing member 1122 are used to seal the assembly gap between the suction nozzle 10 and the liquid storage part 20 to prevent the liquid in the liquid storage chamber 21 The matrix 50 leaks out through this gap.

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

Since the ultrasonic atomization assembly 41 is directly immersed in the liquid storage chamber 21, and the smoke pipe 12 is opened toward the direction of the atomization assembly 41, the liquid matrix 50 is ultrasonically atomized while the liquid matrix 50 is in the ultrasonic wave. Under the vibration, liquid droplets splashed towards the suction nozzle 10 will be generated. On the one hand, the baffle plate 121 is fixed in the gas pipe 12 to prevent the splashed liquid droplets from directly splashing through the gas pipe 12 to the air outlet 1111, so as to avoid The user inhales the liquid matrix 50; on the other hand, the liquid droplets splashed to the baffle 121 can be guided to flow back into the liquid storage chamber 21 along the pipe wall of the second part 123 of the flue gas pipe 12 for re-atomization.

It should be noted that since the ultrasonic atomization component 41 is directly immersed in the liquid storage chamber 21, there will be atomized aerosol particles in the entire liquid storage chamber 21 during ultrasonic atomization, but most of the aerosol particles will be concentrated In the hollow area of the second part 123 of the flue gas pipe 12 , this hollow area can serve as the atomization chamber 124 of the atomizer 100 .

Please continue to refer to FIG. 3 . FIG. 3 shows a schematic cross-sectional view of the suction nozzle 10 connected to the liquid storage portion 20 at the first position. When the suction nozzle 10 is in the first position, an air guide gap 22 is formed between the pipe wall of the flue gas pipe 12 and the inner wall of the liquid storage chamber 21, and the air guide gap 22 serves as the air flow between the air outlet 111 and the atomization chamber 124. A part of the channel, when the user uses the nebulizer 100 to inhale, the outside air enters the atomization chamber 124 and carries the aerosol generated after atomization through the air guide gap 22 and the through hole 126 of the smoke pipe 12. To the pipe body of the first part 122 of the smoke pipe 12 , and then flow to the air outlet hole 1111 to be inhaled by the user, forming the air outlet channel of the nebulizer 100 .

Please continue to refer to FIG. 3 , in order to introduce outside air into the atomization chamber 124 so as to take away the atomized aerosol. The liquid storage part 20 comprises a first air intake pipe 23, a second air intake pipe 24, a third air intake pipe 25 and an air intake hose 26, and the first air intake pipe 23, the second air intake pipe 24 and the third air intake pipe 25 are all rigid Material is made, and intake hose 26 can be soft rubber materials such as silica gel or rubber. The first air intake pipe 23 is inserted into the air intake hole 42 of the base 40, the two ends of the second air intake pipe 24 are tightly sleeved on the first air intake pipe 23 and the third air intake pipe 25, and one end of the air intake hose 26 is tightly sleeved on the On the third air intake pipe 25, the other extends into the atomization chamber 124, so that the outside air passes through the air intake hole 42, the first air intake pipe 23, the second air intake pipe 24, the third air intake pipe 25 and the air intake hose 26 enters the atomization chamber 124 to form the air inlet channel of the atomizer 100, combined with the above-mentioned air outlet channel, so that the air flow channel of the entire atomizer 100 is shown by the R1 arrow route in FIG. 3 .

In order to facilitate the outside air to take away more aerosol after entering the atomization chamber 124, the intake hose 26 is extended to the top area of the atomization chamber 124, so as to be close to the baffle 121 of the flue gas pipe 12, which is easy to understand The deeper the intake hose 26 extends into the atomization chamber 124, the more aerosol smoke particles will be taken away. Therefore, the positions where the intake hose 26 extends into the atomization chamber 124 are different. The amount of aerosol smoke particles taken away by the outside air will also be different. For example, in this embodiment, there is a vertical distance of 15-17mm between the baffle plate 121 of the flue gas pipe 12 and the opening end of the flue gas pipe 12, and the air inlet hose 26 extends into the atomization chamber and is connected with the flue gas pipe 12. There is a vertical distance of 10-12 mm between the open ends of the trachea 12 .

In order to facilitate the actual production, the position where the air intake hose 26 protrudes into the atomization chamber 124 is the same, so that the mouthfeel of each atomizer 100 is consistent during production, and the outer wall of the third air intake pipe 25 is set There is an abutting portion 251 . Specifically, the abutment portion 251 includes an abutment boss extending radially from the outer wall of the third air intake pipe 25 , and the air intake hose 26 is tightly wrapped around the outer wall of the third air intake pipe 25 and abuts against the abutment portion 251 , Furthermore, in actual production, since the length of each intake hose 26 is the same, the position where the intake hose 26 is nested with the third intake pipe 25 is defined by the abutment portion 251, so that each intake hose 26 is set The lengths connected to the third air inlet pipe 25 are the same, thereby ensuring that the position where the air inlet hose 26 extends to the atomizing chamber 124 is also the same.

It is easy to understand that in other embodiments of the present utility model, the abutment portion 251 can also be arranged on the first air intake pipe 23 or the second air intake pipe 24, for example, when it is arranged on the first air intake pipe 23, the first air intake pipe 23 can be Extended so that the intake hose 26 is socketed, without the need to set the second intake pipe 24 and the third intake pipe 25; and when it is arranged on the second intake pipe 24, the second intake pipe 24 is extended to the intake hose 26 socket, without the need to set the third air intake pipe 25. It is only necessary to set a rigid air intake pipe with an abutment portion 251 in the liquid storage portion 20, one end of which is inserted into the air intake hole 42, and the other end is socketed with the air intake hose 26, and is connected to the abutment portion 251 when socketed. Arrival is enough.

Please continue to refer to FIG. 5 , which shows a schematic cross-sectional view of the suction nozzle 10 connected to the liquid storage portion 20 at the second position. In the second position, the suction nozzle 10 cooperates with the liquid storage part 20 to seal the air inlet passage and the air outlet passage of the atomizer 100, thereby sealing the liquid storage chamber 21 and preventing outside air from entering into the storage chamber through the air inlet hole 42 and the air outlet hole 1111. In the liquid cavity 21 , the liquid matrix 50 deteriorates due to long-term contact with the outside air; on the other hand, it can also prevent the liquid matrix 50 from leaking out through the air inlet channel or the air outlet channel when the atomizer 100 is placed horizontally or turned upside down.

Specifically, the flue gas pipe 12 is also provided with a flexible piece 127 surrounding its outer wall, and the flexible piece 127 can be made of silicone or rubber. The inner wall of the liquid storage chamber 21 is formed with an extruding portion 27 for extruding the flexible member 127. The extruding portion 27 shrinks from the inner wall of the liquid storage chamber 21 toward the center of the liquid storage chamber 21, and then the extruding portion 27 A first limiting portion 28 is formed on the upper side, and the first limiting portion 28 is used to limit the suction nozzle to the second position. Therefore, when the suction nozzle is under the action of an external pressing force, the suction nozzle 10 moves from the first position to the second position, the lower end of the connecting portion 112 of the suction nozzle 10 abuts against the first stopper 28, and the suction nozzle 10 is in the first position. The limit part 28 cannot continue to move to the inside of the atomizer 100. At the same time, the extrusion part 27 squeezes the flexible part 127, and the flexible part 127 seals the air guide gap 22 under the action of the extrusion force, thereby sealing the atomization chamber. The airflow channel between the chamber 124 and the air outlet hole 1111 , that is, the air outlet channel is sealed, while the suction nozzle 10 is kept in the second position under the damping effect of the flexible member 127 .

In order to facilitate when the suction nozzle 10 is in the second position, the airflow passage between the air inlet 42 and the atomization chamber 124 , that is, the air inlet passage is sealed. The other end of the air intake hose 26 is configured to extend into the atomization chamber 124 in a curved shape, so the air intake hose 26 will abut against the end wall of the atomization chamber 124 under the action of the deformation restoring force. When the suction nozzle 10 moves from the first position to the second position, the smoke pipe 12 will squeeze the intake hose 26 and make the intake hose 26 continue to bend, so that the bend of the intake hose 26 is sealed The duct of the air intake hose 26 is used to seal the air flow channel between the air intake hole 42 and the atomizing chamber 124 , that is, to seal the air intake channel.

Please continue to refer to FIG. 6 , which shows a perspective view of the fixed cover 30 in one direction. The fixing cover 30 is substantially ring-shaped. The fixing cover 30 has a ring-shaped side surface 31 and a flush end surface 32 . The side surface 31 defines a locking groove 311 , and the end surface 32 defines a through hole 321 . The fixed cover 30 is engaged and fixed with the locking part 20 of the liquid storage part 20 through the locking groove 311 , so that the fixed cover 30 is fixedly installed on the liquid storage part 20 . The air outlet part 111 of the suction nozzle 10 passes through the through hole 321, and the connecting part 112 abuts against the end surface 32 of the fixed cover 30, and the end surface 32 serves as a second stopper for moving the suction nozzle 10 from the second position to the At the first position, the suction nozzle 10 is limited. At the same time, the suction nozzle 10 is kept at the first position under the damping action of the first sealing member 1121 and the second sealing member 1122 .

An ultrasonic atomization assembly 41 is installed on the base 40, and the ultrasonic atomization assembly 41 generally includes an atomization sheet 411, and the atomization sheet 411 is soaked in the liquid storage chamber 21, so that the atomization sheet 411 is directly in contact with the liquid matrix 50, and the atomization sheet 411 The liquid matrix 50 is ultrasonically nebulized to generate an aerosol. In order to facilitate the aerosol generated after atomization to concentrate more in the atomization chamber 124, the smoke pipe 12 is arranged directly above the atomization sheet 411, and the diameter of the second part 123 of the smoke pipe 12 is larger than that of the atomizer. The size of the atomizer 411 extending in the radial direction, so that more aerosol particles generated after atomization can float into the atomization chamber 124, and then the outside air can take away more aerosol particles after entering the atomization chamber 124. The aerosol reaches the vent hole 1111.

The description of the value is that the air intake hole 42 is set on the base 40, so that the outside air is taken in from the bottom of the atomizer 100, and the bottom air intake method can greatly simplify the structure of the upper end of the product and reduce the number of parts compared to the top air intake structure. Quantity, to make the parts more regular, thus improving the tightness against liquids and gases.

Combining the above, the working principle of the atomizer 100 is as follows:

When the user needs to use the nebulizer 100 for inhalation, pull the suction nozzle to the first position. At this time, there is an air guide gap 22 between the outer wall of the smoke pipe 12 and the inner wall of the liquid storage chamber 21, and the smoke pipe 12 does not Squeeze the air inlet hose 26, now the airflow passage (air intake passage) between the air inlet 42 and the atomization chamber 124 is connected, and the airflow passage (air outlet passage) between the air outlet hole 1111 and the atomization chamber 124 ) is also turned on, the user sucks in the air outlet 1111, the nebulizer 100 generates a negative pressure inside, and the outside air enters the atomization chamber 124 through the air intake channel, and at the same time, the atomizing sheet 411 performs ultrasonic atomization on the liquid matrix 50 to generate The aerosol released into the atomization chamber 124, the outside air carries the aerosol through the air outlet channel and flows to the air outlet hole 1111 for the user to inhale.

When the user does not need to use the atomizer 100, or when the atomizer 100 is in a storage state or a transportation state, the suction nozzle 10 is pressed from the first position to the second position, and the flexible part of the smoke pipe 12 of the suction nozzle 10 127 is squeezed and sealed by the inner wall of the liquid storage chamber 21 to seal the air guide gap 22, so that the airflow channel (air outlet channel) between the air outlet hole 1111 and the atomization chamber 124 is closed; at the same time, the smoke pipe 12 squeezes the intake hose 26 Continue to bend to seal the pipeline of the intake hose 26, thereby closing the airflow channel (air intake channel) between the air intake hole 42 and the atomization chamber 124, thereby making the atomizer 100 unable to suck, and also preventing When the atomizer 100 is placed horizontally or inverted, the liquid matrix 50 leaks out through the air inlet channel or the air outlet channel.

It is worth noting that the atomization effect of the atomizer 100 is related to the power of the atomization sheet 411 of the mist ultrasonic atomization assembly, the vibration frequency of the atomization sheet 411 and the liquid level height after the liquid matrix 50 is poured into the atomizer 100. It is related, the atomizing sheet 411 has the optimum liquid level height range adapted to it within a certain power range, when the liquid level height is within this range, the atomization effect will be ideal, if it exceeds or falls below this liquid level range, the fog The atomization effect is not ideal. In the above embodiment, preferably, the power of the atomizing sheet 411 is set to 10-12W, and the corresponding liquid level height ranges from 5-25mm. In addition, the atomizing sheet 411 usually has different vibration frequencies, and the higher the vibration frequency, the thinner the atomizing sheet is. Under the same outer diameter of the atomizing sheet, the volume of the atomizing sheet body is smaller, and the atomizing sheet is more stable. The power supported by the sheet is also smaller, so that different vibration frequencies also have an optimal liquid level range adapted to it. In the above embodiment, it is preferable to set the vibration frequency range of the atomizing sheet 411 to 2.4 ~ 3Mhz , and the corresponding optimal liquid level height is set to 20-40mm.

It should be noted that, in another embodiment of the present utility model, the atomizer 100 can also close and conduct the air flow channel without extruding and sealing the smoke pipe 12, for example, it can be connected to the suction nozzle 10a The trachea 11a (shown in the figure) and the air outlet tube 12a (not shown in the figure) are shown in FIGS. 7 and 8 .
