With respect to the nozzle assembly 10, referring still to fig. 4, fig. 4 shows an exploded view of the nozzle 10 from one perspective, and also referring to fig. 3 in combination. The suction nozzle assembly 10 includes a suction nozzle cover 11 and a fume pipe 12 connected to the suction nozzle cover 11. The suction nozzle cover 11 comprises an air outlet part 111 and a connecting part 112 connected with the liquid storage part 20, wherein the air outlet part 111 is provided with an air outlet hole 1111 for the aerosol generated after atomization to escape from the atomizer; the outer wall of the connecting portion 112 is surrounded by a first seal 1121 and a second seal 1122, and the first seal 1121 and the second seal 1122 are used to seal an assembly gap between the nozzle assembly 10 and the liquid storage portion 20, so as to prevent the liquid substrate 50 in the liquid storage cavity 21 from leaking out through the gap.

The flue pipe 12 has a cylindrical structure with both ends open, one end of which is connected to the connection portion 112 of the mouthpiece cover 11, and the other end of which extends in the liquid storage chamber 21 in the axial direction of the atomizer 100. A baffle 121 is arranged in the flue gas pipe 12, the baffle 121 divides the flue gas pipe 12 into a first part 122 and a second part 123 along the axial direction, and the first part 122 and the second part 123 are hollow structures. The baffle 121 and the pipe wall of the second portion 123 define an atomization chamber 124 of the atomizer 200, the pipe wall of the first portion 122 is provided with a through hole 125 communicated with the atomization chamber 124, and atomized aerosol can enter the first portion 122 through the through hole 125. The first portion 122 is inserted into the air outlet hole 1111 of the air outlet portion 111 by interference fit, so that the entire flue pipe 12 is fixedly connected to the mouthpiece cover 11 on the one hand, and the aerosol entering the flue pipe 12 is guided into the air outlet hole 1111 on the other hand, so that the user can inhale the aerosol at the mouthpiece cover 10.

The ultrasonic atomization assembly 50 comprises an atomization sheet 51, the atomization sheet 51 is exposed in the liquid storage cavity 21, so that the atomization sheet 51 can be soaked in liquid matrix in the liquid storage cavity 21, the flue gas pipe 12 is arranged in an opening way towards the ultrasonic atomization assembly 50, so that the atomization cavity 124 is communicated with the liquid storage cavity 21, liquid matrix can generate liquid drops which are sputtered towards the suction nozzle assembly 10 under the vibration of ultrasonic waves while being subjected to ultrasonic atomization, and a baffle 121 is fixedly arranged in the flue gas pipe 12, so that the sputtered liquid drops can be prevented from being directly sputtered to the air outlet 1111 through the flue gas pipe 12 on the one hand, and the liquid matrix is prevented from being sucked by a user; on the other hand, the droplets sputtered onto the baffle 121 may be directed to flow back along the wall of the second portion 123 of the flue gas duct 12 into the liquid reservoir 21 for re-atomization.

It should be noted that, since the atomizing sheet is directly immersed in the liquid storage cavity 21, atomized aerosol particles exist in the entire liquid storage cavity 21 during ultrasonic atomization, but most of the aerosol particles are concentrated in the hollow area of the second portion 123 of the flue gas tube 12, so that the hollow area can be used as the atomizing chamber 124 of the atomizer 100.

With continued reference to fig. 3, fig. 3 is a schematic cross-sectional view of the nozzle assembly 10 in a first position coupled to the reservoir 20. When the suction nozzle assembly 10 is located at the first position, the pipe wall of the flue gas pipe 12 and the inner wall of the liquid storage cavity 21 form an air guide gap 22, the air guide gap 22 is used as a part of an air flow channel between the air outlet hole 111 and the atomization cavity 124, when a user sucks the air by using the atomizer 100, external air enters the atomization cavity 124 and carries the atomized aerosol into the pipe body of the first part 122 of the flue gas pipe 12 through the air guide gap 22 and the through hole 126 of the flue gas pipe 12, and then flows to the air outlet hole 1111 to be sucked by the user, so as to form an air outlet channel of the atomizer 100.

With continued reference to fig. 5, fig. 5 shows a perspective view of the base 40 in one orientation. To introduce external air into the atomizing chamber 124 to carry away the atomized aerosol, the base 40 is provided with an air inlet 41 and an air duct 42 inserted into the air inlet 41, the air duct 42 extending in the liquid storage chamber 21 along the axial direction of the atomizer 100. The end of the air duct 42 is connected with an air valve 43, and external air can enter the atomization chamber 124 through the air inlet hole 41, the air duct 42 and the air valve 43, so that an air inlet channel of the atomizer 100 is formed, and aerosol in the atomization chamber 124 is carried out of the atomizer 100 through the air outlet channel, as shown by an air flow route R1 in FIG. 3.

The gas valve 43 can close or open the gas inlet passage and thus the gas flow passage of the entire atomizer 100. Specifically, referring to fig. 6, fig. 6 shows an exploded view of the air valve 43 in one view, and the air valve 43 includes a first abutment 431, a movable member 432, an elastic member 433, a second abutment 434, and a tubular body 435. The tubular body 435 has a first end and a second end opposite to each other in the axial direction, the first end and the second end are both open, the tubular body 435 is configured as a hollow structure, and the tubular body 435 is sleeved at the end of the air duct 42 through the opening of the second end, so that external air can enter the pipe of the tubular body 435, that is, the air valve 43 through the air duct 42.

The inner wall of the tubular body 435 extends to form a first resisting part 4351, when the tubular body 435 is sleeved on the air duct 42, the end part of the air duct 42 is abutted against the first resisting part 4351, a first through hole 4352 is formed in the first resisting part 4351, and external air can enter the tubular body 435 through the first through hole 4352, namely, enter the air valve 43, so that the first through hole 4352 can serve as an air inlet of the air valve 43, and air flows into the air valve 43. The first end of the tubular body 435 is fitted with a first abutment 431, while the inside of the tubular body 435 is provided with a second abutment 434, the second abutment 434 abutting against the first abutment 4351. The second abutting piece 434 forms a third through hole 4341 penetrating through the body axially, the third through hole 4341 is communicated with the first through hole 4352, and the second abutting piece 434 is made of flexible materials, such as silica gel or rubber. An elastic member 433 is abutted between the first abutting member 431 and the second abutting member 434, and the elastic member 433 adopts a spiral spring. The movable member 432 extends axially into the pipe of the tubular body 435, at least a portion of the movable member 432 protrudes out of the tubular body 435 through the opening of the first end of the tubular body 435, the surface of the movable member 432 extends to form a second resisting portion 4321, the elastic member 433 is sleeved on the movable member 432, and a portion of the elastic member 433 can be abutted against the second resisting portion 4321.

The wall of the tubular body 435 is provided with a second through hole 4353 for the air supply and escape valve 43, and the second through hole 4353 is used as an air outlet of the air valve. When the air valve 43 is opened, the external air flow enters the air valve 43 through the first through hole 4352, and flows out of the air valve 43 through the second through hole 4353, and then enters the atomizing chamber 124. When the air valve is closed, the external air flow cannot enter the air valve 43 through the first through hole 4352, thereby closing the air inlet passage, that is, the air flow passage of the atomizer 100.

Specifically, when the suction nozzle assembly 10 moves from the first position to the second position, the flue gas pipe 12 of the suction nozzle assembly 10 abuts against the movable member 432 of the air valve 43, and applies a pressing force to the movable member 432, the movable member 432 moves from the first end of the tubular body 435 toward the second end of the tubular body 435 under the action of the pressing force of the suction nozzle assembly 10, at this time, the movable member 432 extends into the third through hole 4341 and is in interference fit with the third through hole 4341, thereby sealing the third through hole 4341, and external air cannot enter into the air valve 43 through the third through hole 4341, so that the air valve 43 closes the air flow passage of the atomizer 100. Meanwhile, the elastic member 433 is pressed by the second resisting portion 4321 of the movable member 432 along with the movement of the movable member 432, and thus compressed by the second resisting portion 4321.

When the suction nozzle assembly 10 moves from the second position to the first position, the flue gas pipe 12 of the suction nozzle assembly 10 no longer applies pressure to the movable member 432, meanwhile, the second resisting part 4321 of the movable member 432 is not pressing the elastic member 433, the elastic member 433 recovers deformation, the movable member 432 moves from the second end of the tubular body 435 towards the first end under the action of the deformation restoring force, so that the movable member 432 is separated from the third through hole 4341, and external air can enter the tubular body 435 from the third through hole 4341 and escape from the second through hole 4353 of the tubular body 435, so that the air valve 43 opens the air inlet channel, that is, the air flow channel of the atomizer 100. It is to be understood that the movable member 432 may be used as the air valve core of the air valve 43, and therefore, in other embodiments of the present utility model, the air valve 43 may take other forms well known to those skilled in the art, and only when the suction nozzle assembly 10 moves to the first position, the air valve core can be pushed to move in the axial direction to seal the air inlet of the air valve 43, and when the suction nozzle assembly 10 releases the pressure applied to the air valve core of the air valve 43 to release the seal of the air inlet of the air valve 43.

It should be noted that, the second through hole 4353, that is, the air outlet of the air valve 43, is disposed on the wall of the tubular body 435, but not on the end surface of the first end of the tubular body 435, so as to avoid that when the droplets sputtered onto the baffle 121 flow back along the wall of the second portion 123 of the flue gas tube 12, if the air outlet is disposed on the end surface of the first end of the tubular body 435, the flowing back droplets will enter the tubular body 435 through the air outlet, and then flow out of the atomizer 100 through the air inlet channel to generate leakage.

With continued reference to fig. 7, fig. 7 is a schematic cross-sectional view of the nozzle assembly 10 in the second position when connected to the reservoir 20. In the second position, the outer wall of the flue gas tube 12 of the suction nozzle assembly 10 is in interference fit with the inner wall of the liquid storage cavity 21, so that a seal is generated between the outer wall of the flue gas tube 12 and the inner wall of the liquid storage cavity 21, and external air is prevented from entering the liquid storage cavity 21 through the air outlet channel. Meanwhile, in the second position, the air valve 43 closes the air inlet channel, so that the liquid matrix in the liquid storage cavity 21 is completely isolated from the external air, and therefore, the suction nozzle assembly 10 can be pressed to the second position by the atomizer 100 when the atomizer 100 is not in use, and the air outlet channel and the air inlet channel of the atomizer 100 are both closed, so that the liquid matrix in the liquid storage cavity 21 is effectively prevented from being deteriorated due to contact with the external air.

In particular, the flue pipe 12 is provided with a flexible member 127 surrounding its outer wall, which flexible member 127 may be of silicone or rubber. The inner wall of the liquid storage cavity 21 is formed with a squeezing part 27 for squeezing the flexible member 127, the squeezing part 27 is formed by shrinking inwards from the inner wall of the liquid storage cavity 21 towards the center direction of the liquid storage cavity 21, and then a first limiting part 28 is formed above the squeezing part 27, and the first limiting part 28 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 112 of the suction nozzle 10 is abutted against the first limiting portion 28, the suction nozzle 10 cannot continue to move towards the interior of the atomizer 100 under the limit of the first limiting portion 28, meanwhile, the extrusion portion 27 extrudes the flexible member 127, and the flexible member 127 seals the air guide gap 22 under the action of the extrusion force, so that the air flow channel between the atomizing chamber 124 and the air outlet hole 1111, namely, the air outlet channel is sealed, and meanwhile, the suction nozzle 10 is kept at the second position under the damping action of the flexible member 127.

With continued reference to fig. 8, the atomizer 100 further includes a stationary cover 30, and fig. 8 shows a perspective view of the stationary cover 30 in one direction. The fixed cover 30 is substantially annular, the fixed cover 30 includes a side surface 31 and a flush end surface 32, the side surface 31 defines a clamping groove 311, and the end surface 32 defines a through hole 321. The fixed cover 30 is engaged and fixed with the liquid storage portion 20 by the engaging groove 311, so that the fixed cover 30 is fixedly mounted on the liquid storage portion 20. The air outlet 111 of the suction nozzle assembly 10 penetrates the through hole 321, and the connecting portion 112 abuts against the end surface 32 of the fixed cover 30, and the end surface 32 serves as a second limiting portion for limiting the suction nozzle assembly 10 when the suction nozzle assembly 10 moves from the second position to the first position. Meanwhile, the first sealing member 1121 and the second sealing member 1122 are surrounded on the outer wall of the suction nozzle assembly 10, the first sealing member 1121 and the second sealing member 1122 are made of flexible materials, such as silica gel or rubber, and the suction nozzle assembly 10 is kept in the first position under the damping action of the first sealing member 1121 and the second sealing member 1122.

Through the above description, the nozzle assembly 10 of the atomizer 100 provided by the present utility model has a first position and a second position relative to the liquid storage portion 20, the nozzle assembly 10 can move between the first position and the second position, when the nozzle assembly 10 is pushed to move from the first position to the second position, the nozzle assembly 10 presses the air valve 43 to close, thereby closing the air flow channel of the atomizer 100, and the atomizer 100 cannot be used by a user; when the user needs to use the atomizer 100, the suction nozzle assembly 10 can be pulled from the second position to the first position, at this time, the suction nozzle assembly 10 releases the extrusion force to the air valve 43, the air valve 43 is opened, and then the air flow channel of the atomizer 100 is opened, so that the user can use the atomizer 100 to perform suction, and the interactivity between the user and the atomizer 100 can be improved.

When the suction nozzle assembly 10 moves from the first position to the second position, the suction nozzle assembly 10 pushes the movable piece 432 of the air valve 43 to seal the air inlet channel, and meanwhile, the flue gas pipe 12 of the suction nozzle assembly 10 is in interference fit with the inner wall of the liquid storage cavity 21, so that the flue gas pipe 12 seals the air outlet channel, and the suction nozzle assembly 10 can simultaneously open or close the air outlet channel and the air inlet channel.

In other embodiments of the present utility model, the nozzle assembly 10 may also be configured to sequentially open or close the outlet channel and the inlet channel. Specifically, when the suction nozzle assembly 10 pushes the movable member 432 of the air valve 43 into the third through hole 4341, the movable member 432 is in interference fit with the third through hole 4341 to seal the third through hole 4341. At this time, the flue gas pipe 12 of the suction nozzle assembly 10 is not abutted with the inner wall of the liquid storage cavity 21, and along with the further downward movement of the suction nozzle assembly 10, the flue gas pipe 12 is abutted with the inner wall of the liquid storage cavity 21 and in interference fit with the inner wall of the liquid storage cavity 21, so that the air outlet channel is sealed, and the effect that the air inlet channel and the air outlet channel are sealed successively is achieved.

Since the atomizing sheet 51 is in a disc shape and has a certain diameter, the air duct 42 is disposed near the inner wall of the liquid storage chamber 21, so that a sufficient space is left for placing the atomizing sheet 51.

The air valve 43a is integrally formed of a flexible software material, and the air valve 43a includes a first portion 431a and a second portion 432a elastically connected to the first portion 431 a. The first portion 431a is configured in a hollow cylindrical shape with both ends open, and the hollow portion of the cylindrical body is used to form an air passage of the air valve 43a. The second portion 432a is resiliently coupled to the proximal end 4311a of the first portion 431a, and the first portion 431a is disposed closely about the end of the air duct 42a such that ambient air may enter the air valve 43a through the air duct 42 a. The second portion 432a is capable of reversing movement in a direction toward or away from the first portion 431 to effect closing or opening of the air valve 43a.

Specifically, when the suction nozzle assembly 10 moves to the second position, the suction nozzle assembly 10 presses the second portion 432a of the air valve 43a, and pushes the second portion 432a to turn over toward the first portion 431a, so that the second portion 432a moves to the proximal end 4311a of the first portion 431a and covers the opening of the proximal end 4311a, thereby closing the air valve 43a, and further closing the air flow channel of the atomizer 100a, and the user cannot use the atomizer 100a to perform suction. It will be readily appreciated that the opening at the distal end 4312a of the first portion 431a acts as an air inlet for the air valve 43a and the opening at the proximal end 4311a of the first portion 431a acts as an air outlet for the air valve 43a.

When the suction nozzle assembly 10 moves to the first position, the pressing force applied by the suction nozzle assembly 10 to the second portion 432a is released, the second portion 432a is turned over by the elastic restoring force in a direction away from the first portion 431a, and simultaneously is separated from the opening of the proximal end 4311a of the first portion 431a, so that the opening of the proximal end 4311a is exposed, and external air can enter the air valve 43a through the opening of the distal end 4312a of the first portion 431a and escape through the opening of the proximal end 4311a of the first portion 431a, thereby opening the air valve 43a and thus opening the air flow channel of the atomizer 100a, and a user can use the atomizer 100 to perform suction.
