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 application. The ultrasonic atomizer 100 has opposite proximal and distal ends 101 and 102, and includes a suction nozzle 10, a liquid storage portion 20, a fixed cover 30, and a base 40, wherein the suction nozzle 10 is mounted on the liquid storage portion 20 at the proximal end of the atomizer 100, the base 30 is mounted on the liquid storage portion 20 at the distal end of the atomizer 100, and the suction nozzle 10 has a first position and a second position with respect to the liquid storage portion 20, i.e., the suction nozzle 10 is connectable to the liquid storage portion 20 at the first and second positions. For example, the suction nozzle 10 may be movable from the first position to the second position by an external pressing force, and may be movable from the second position to the first position by an external pulling force. A stationary cover 30 is secured to the proximal end of the reservoir 20 for limiting the movement of the nozzle 10 from the second position to the first position to define the nozzle 10 in the first position. The inner walls of the mouthpiece 10, the base 40 and the reservoir 20 together define a reservoir 21 forming an atomizer 100, the reservoir 21 being adapted to store an atomized liquid matrix 50. The base 40 is provided with an ultrasonic atomization assembly 41, the ultrasonic atomization assembly is directly soaked in the liquid storage cavity 21, the ultrasonic atomization assembly 40 is used for carrying out ultrasonic atomization on a liquid matrix to generate aerosol which can be sucked, and the base 40 is also provided with an air inlet hole 42 for external air to enter the atomizer 100. It should be noted that, the liquid matrix 50 may be a smoke liquid or a liquid medicine, so the atomizer 100 provided in the embodiment of the application may be used in the electronic cigarette or medical field.

With reference to the above-mentioned suction nozzle 10, referring to fig. 4, fig. 4 shows a schematic step diagram of the suction nozzle 10 at a view angle, and referring to fig. 3 in combination, the suction nozzle 10 includes a suction nozzle cover 11 and a flue gas 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 suction nozzle 10 and the liquid storage portion 20, so as to prevent the liquid matrix 50 in the liquid storage cavity 21 from leaking out through the gap.

The smoke tube 12 has a tubular structure with two open ends, one end of the smoke tube is connected with the connecting part 112 of the suction nozzle cover 11, and the other end of the smoke tube extends in the liquid storage cavity 21 along the axial direction of the atomizer 100 and faces the ultrasonic atomization assembly 41. 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 126 communicated with the atomization chamber 124, and atomized aerosol can enter the first portion 122 through the through hole 126. The first portion 122 is inserted into the air outlet hole 1111 of the air outlet 111 by means of an interference fit, so that on the one hand the entire flue pipe 12 is fixedly connected to the mouthpiece cover 11 and on the other hand the aerosol entering the flue pipe 12 is guided into the air outlet hole 1111, so that the user can inhale the aerosol at the mouthpiece 10.

Because the ultrasonic atomization assembly 41 is directly soaked in the liquid storage cavity 21, and the direction of the flue gas pipe 12 facing the atomization assembly 41 is opened, the liquid matrix 50 can generate liquid drops which are sputtered towards the suction nozzle 10 under the vibration of ultrasonic waves while the liquid matrix 50 is ultrasonically atomized, and the baffle 121 fixedly arranged in the flue gas pipe 12 can prevent the sputtered liquid drops from directly sputtering to the air outlet hole 1111 through the flue gas pipe 12 on the one hand, so that a user is prevented from sucking the liquid matrix 50; 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 ultrasonic atomizing assembly 41 is directly immersed in the liquid storage cavity 21, atomized aerosol particles exist in the whole 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 pipe 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 10 in the first position connected to the reservoir 20. When the suction nozzle 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, and 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 atomizer 100, external air enters the atomization cavity 124 and carries the aerosol generated after atomization 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. 3, ambient air is introduced into the atomizing chamber 124 to entrain the atomized aerosol. The liquid storage portion 20 includes a first air inlet pipe 23, a second air inlet pipe 24, a third air inlet pipe 25 and an air inlet hose 26, wherein the first air inlet pipe 23, the second air inlet pipe 24 and the third air inlet pipe 25 are made of rigid materials, and the air inlet hose 26 can be made of soft rubber materials such as silica gel or rubber. The first air inlet pipe 23 is inserted into the air inlet hole 42 of the base 40, two ends of the second air inlet pipe 24 are tightly sleeved on the first air inlet pipe 23 and the third air inlet pipe 25, one end of the air inlet hose 26 is tightly sleeved on the third air inlet pipe 25, and the other end of the air inlet hose extends into the atomization chamber 124, so that external air enters the atomization chamber 124 through the air inlet hole 42, the first air inlet pipe 23, the second air inlet pipe 24, the third air inlet pipe 25 and the air inlet hose 26 to form an air inlet channel of the atomizer 100, and the air outlet channel is combined, so that the air flow channel of the whole atomizer 100 is shown as an arrow route R1 in fig. 3.

In order to facilitate the entrainment of more aerosol after the ambient air enters the atomizing chamber 124, the air inlet hose 26 extends to the top region of the atomizing chamber 124 to be adjacent to the baffle 121 of the flue gas duct 12, it is readily understood that the deeper the air inlet hose 26 extends into the atomizing chamber 124, the more aerosol particles are entrained, and therefore the different locations the air inlet hose 26 extends into the atomizing chamber 124, the different aerosol particles are entrained by the ambient air. For example, in this embodiment, the baffle 121 of the flue gas tube 12 has a vertical spacing of 15-17 mm from the open end of the flue gas tube 12, and the air inlet hose 26 extends into the atomizing chamber and has a vertical spacing of 10-12 mm from the open end of the flue gas tube 12.

In order to facilitate that the position of the air inlet hose 26 extending into the atomizing chamber 124 is the same in practice, so that the mouth feel of the suction of each atomizer 100 is uniform in production, the outer wall of the third air inlet pipe 25 is provided with an abutment 251. Specifically, the abutment portion 251 includes an abutment boss extending from the outer wall of the third air inlet pipe 25 in the radial direction, and the air inlet hose 26 is tightly sleeved on the outer wall of the third air inlet pipe 25 and abuts against the abutment portion 251, so that in actual production, since the length of each air inlet hose 26 is the same, the position where the air inlet hose 26 is sleeved on the third air inlet pipe 25 is defined by the abutment portion 251, so that the length of each air inlet hose 26 sleeved on the third air inlet pipe 25 is the same, and further, the position where the air inlet hose 26 extends to the atomization chamber 124 is also the same.

It is to be readily understood that, in other embodiments of the present application, the abutting portion 251 may be provided on the first air intake pipe 23 or the second air intake pipe 24, for example, when provided on the first air intake pipe 23, the first air intake pipe 23 may be extended to be sleeved with the air intake hose 26, without providing the second air intake pipe 24 and the third air intake pipe 25; when the third air inlet pipe 25 is arranged on the second air inlet pipe 24, the second air inlet pipe 24 is prolonged to be sleeved with the air inlet hose 26, and the third air inlet pipe 25 is not needed. The liquid storage portion 20 is provided with a rigid air intake pipe having an abutting portion 251, one end of which is inserted into the air intake hole 42, and the other end of which is sleeved with the air intake hose 26 and abuts against the abutting portion 251 at the time of the sleeve-joint.

With continued reference to fig. 5, fig. 5 shows a schematic cross-sectional view of the nozzle 10 in the second position when connected to the reservoir 20. In the second position, the suction nozzle 10 and the liquid storage part 20 cooperate to seal the air inlet channel and the air outlet channel of the atomizer 100, so as to seal the liquid storage cavity 21, and prevent external air from entering the liquid storage cavity 21 through the air inlet hole 42 and the air outlet hole 1111, and the liquid substrate 50 is in contact with the external air for a long time to deteriorate; on the other hand, the liquid matrix 50 is prevented from leaking out through the inlet or outlet channels when the atomizer 100 is placed in a lateral direction or inverted.

In particular, the flue gas tube 12 is further 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 pressing portion 27 for pressing the flexible member 127, the pressing portion 27 is formed by shrinking inward from the inner wall of the liquid storage cavity 21 toward the center direction of the liquid storage cavity 21, and further a first limiting portion 28 is formed above the pressing portion 27, and the first limiting portion 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.

To facilitate the sealing of the air flow path, i.e. the air inlet path, between the air inlet aperture 42 and the nebulization chamber 124 when the mouthpiece 10 is in the second position. The other end of the air intake hose 26 is configured to extend into the atomizing chamber 124 in a curved shape, so that the air intake hose 26 will abut against the end wall of the atomizing chamber 124 under the deformation restoring force. When the suction nozzle 10 moves from the first position to the second position, the air inlet hose 26 is pressed by the air duct 12, so that the air inlet hose 26 is further bent, and the bent portion of the air inlet hose 26 seals the duct of the air inlet hose 26, so as to seal the air flow channel between the air inlet hole 42 and the atomizing chamber 124, that is, seal the air inlet channel.

With continued reference to fig. 6, fig. 6 shows a perspective view of the stationary cover 30 in one orientation. The fixed cover 30 is substantially annular, the fixed cover 30 has an annular 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 fastening portion 20 of the liquid storage portion 20 through the fastening 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 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 10 when the suction nozzle 10 moves from the second position to the first position. At the same time, the suction nozzle 10 is maintained in the first position by the damping action of the first and second seals 1121, 1122.

The ultrasonic mist assembly 41 is mounted on the base 40, and the ultrasonic mist assembly 41 generally includes a mist plate 411, the mist plate 411 being immersed in the liquid storage chamber 21 so that the mist plate 411 is in direct contact with the liquid substrate 50, the mist plate 411 ultrasonically atomizing the liquid substrate 50 to generate aerosol. In order to facilitate more concentration of the aerosol generated after atomization in the atomization chamber 124, the flue gas pipe 12 is disposed directly above the atomization sheet 411, and the pipe diameter of the second portion 123 of the flue gas pipe 12 is larger than the extending dimension of the atomization sheet 411 along the radial direction, so that the aerosol particles generated after atomization can more float into the atomization chamber 124, and further, after the external air enters the atomization chamber 124, more aerosol can be taken away to the air outlet 1111.

By way of illustration, the air inlet holes 42 are provided in the base 40 so that ambient air is introduced from the bottom of the atomizer 100, and the bottom air inlet mode can greatly simplify the structure of the upper end of the product relative to the top air inlet structure, reduce the number of parts, and make the parts more regular so as to improve the tightness to liquid and gas.

In combination with the above, the operating principle of the atomizer 100 is as follows:

when the user needs to use the atomizer 100 to perform suction, the suction nozzle is drawn to the first position, at this time, an air guide gap 22 exists between the outer wall of the flue pipe 12 and the inner wall of the liquid storage cavity 21, the flue pipe 12 does not squeeze the air inlet hose 26, at this time, an air flow channel (air inlet channel) between the air inlet hole 42 and the atomizing cavity 124 is also conducted, the user performs suction at the air outlet hole 1111, negative pressure is generated inside the atomizer 100, external air enters the atomizing cavity 124 through the air inlet channel, meanwhile, aerosol generated by ultrasonic atomization of the liquid substrate 50 by the atomizing sheet 411 is released into the atomizing cavity 124, and the external air carries the aerosol to flow to the air outlet hole 1111 through the air outlet channel 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 transport state, the suction nozzle 10 is pressed from the first position to the second position, the flexible member 127 of the smoke tube 12 of the suction nozzle 10 is pressed by the inner wall of the liquid storage chamber 21 to seal the air guide gap 22, so that the air flow passage (air outlet passage) between the air outlet hole 1111 and the atomizing chamber 124 is closed; at the same time, the air pipe 12 presses the air inlet hose 26 to continue to bend to seal the pipe of the air inlet hose 26, so as to close the air flow channel (air inlet channel) between the air inlet hole 42 and the atomization chamber 124, so that the atomizer 100 cannot perform suction, and the liquid matrix 50 can be prevented from leaking out through the air inlet channel or the air outlet channel when the atomizer 100 is placed transversely or inverted.

It should be noted that, the atomization effect of the atomizer 100 is related to the power of the atomizing plate 411 of the atomizing ultrasonic atomization assembly, the vibration frequency of the atomizing plate 411, and the liquid level after the liquid substrate 50 is poured into the atomizer 100, the atomizing plate 411 has an optimal liquid level range adapted to the power range, when the liquid level is within 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 411 is preferably set to 10-12W, and the corresponding range of the liquid level is 5-25 mm.
