The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] See also Figure 1 and 3 The atomizer 1 includes a housing 101, an atomizing core 102, a nozzle 103, and a one-way vent 104. The housing 101 has a liquid storage chamber 1011 for storing a liquid matrix. The atomizing core 102 is fluidically connected to the liquid storage chamber 1011 so that the atomizing core 102 can absorb the liquid matrix in the liquid storage chamber 1011. The atomizing core 102 is used to atomize the liquid matrix to generate aerosol. The nozzle 103 is connected to the housing 101 and is provided with an air inlet 1031. The nozzle 103 is used for the user's mouth to hold. The user can inhale the aerosol generated by the atomizing liquid matrix of the atomizing core 102 into the oral cavity through the air inlet 1031. Please refer to Figure 3 and Figure 4 , Figure 3 1 shows a schematic diagram of the atomizer when the one-way vent 104 is closed, Figure 4The schematic diagram of the atomizer is shown when the one-way vent 104 is opened. The one-way vent 104 is arranged between the air inlet 1031 and the atomizer core 102. The one-way vent 104 is kept in a normally closed state and is opened when the mouthpiece 103 is inhaled to allow the aerosol to flow from the atomizer core 102 through the one-way vent 104 into the air inlet 1031 and then into the user's mouth; please refer to Figure 3 When the user does not suck the nozzle 103, the one-way vent 104 is closed. At this time, the one-way vent 104 can block at least part of the liquid and gas from flowing through. In this embodiment, a one-way vent 104 is provided between the atomizer core 102 and the air inlet 1031, and when the suction nozzle 103 is sucked, the one-way vent 104 is opened, and the aerosol can flow through the one-way vent 104, and when the suction nozzle 103 is not sucked, the one-way vent 104 is closed, thereby blocking at least part of the liquid and gas from flowing through. On the one hand, when the atomizer 1 is inverted, at least part of the liquid can be intercepted, and the liquid is prevented from flowing into the air inlet 1031 through the atomizer core 102, thereby preventing the liquid from leaking through the air inlet 1031; on the other hand, the external liquid can be reduced from entering the atomizer core 102 from the air inlet 1031, which is beneficial to increasing the waterproof performance of the atomizer 1, and reducing the influence of the external liquid on the aerosol generated by the atomized liquid matrix of the atomizer core 102, thereby ensuring the taste of the aerosol, and also preventing the liquid formed by the condensation of the aerosol in the channel between the atomizer core and the suction nozzle from flowing back to the atomizer core 102.

[0034] In some embodiments, see Figure 3 The shell and the suction nozzle 103 are integrally formed, which can reduce the steps of assembling the shell and the suction nozzle 103 and is conducive to improving production efficiency.

[0035] It is understandable that the housing and the suction nozzle 103 may also be connected by assembly.

[0036] In some embodiments, the one-way vent 104 may include a duckbill valve or may have a working principle similar to a duckbill valve, and the one-way vent 104 is opened or closed mainly according to the air pressure difference on its two opposite sides. Figure 3 and Figure 5 In the embodiment shown, the one-way vent 104 includes a plurality of elastic membranes 1041, which are symmetrically distributed or circumferentially distributed, and the plurality of elastic membranes 1041 are closed together, so that the one-way vent 104 remains closed to block the fluid passage between the air inlet 1031 and the atomizer core 102. Figure 4 and Figure 6 When the nozzle 103 is sucked, the multiple elastic membranes 1041 are elastically deformed, so that the multiple elastic membranes 1041 are opened to form openings 1042, so as to allow airflow to flow through the openings 1042; see Figure 3 and Figure 5When the suction nozzle 103 is not sucked, the multiple elastic membranes 1041 close together and block the fluid channel between the suction port 1031 and the atomizer core 102, so as to block at least part of the liquid or gas from flowing through the one-way vent 104. In this embodiment, by providing multiple elastic membranes 1041, when the suction nozzle 103 is sucked, the multiple elastic membranes 1041 are opened, and when not sucked, the multiple elastic membranes 1041 are closed together, and there is no need to manually open or close the one-way vent 104, which is very convenient.

[0037] In some embodiments, the thickness of the elastic diaphragm 1041 is between 0.02 mm and 0.2 mm. If the thickness of the elastic diaphragm 1041 is too thick, the suction resistance will increase, and if the thickness of the elastic diaphragm 1041 is too thin, its ability to block the flow of liquid or gas will be weakened. Therefore, the thickness of the elastic diaphragm 1041 is selected to be between 0.02 mm and 0.2 mm, which can take into account both the suction resistance of suction and its ability to block the flow of liquid or air.

[0038] Furthermore, the thickness of the elastic membrane 1041 is 0.1 mm.

[0039] In some embodiments, see Figure 3 The atomizer 1 further comprises an airway tube 105, the airway tube 105 having a relative proximal end 1051 and a distal end 1052, the proximal end 1051 of the airway tube 105 being in communication with the inhalation port 1031, it can be understood that the airway tube 105 can be integrally formed with the mouthpiece 103, and the distal end 1052 of the airway tube 105 is arranged toward the atomizing core 102. At least a part of the one-way vent 104 is arranged between the atomizing core 102 and the distal end 1052 of the airway tube 105, so as to prevent the fluid (liquid and / or gas) from flowing between the atomizing core 103 and the airway tube 105 when the mouthpiece 103 is not sucked, and when the mouthpiece 103 is sucked, the one-way vent 104 is opened, and the aerosol generated by the atomizing core 102 can flow into the inhalation port 1031 along the airway tube 105 after passing through the opening 1042 of the one-way vent 104, and then enter the user's mouth. When the aerosol flows through the airway tube 105, part of the aerosol will condense on the tube wall of the airway tube 105 to form condensate. When the condensate accumulates more, it will flow downward along the airway tube 105 under the action of gravity. If there is no one-way vent 104 to block it, the condensate will drip onto the atomizer core 102, which is easy to affect the taste of the aerosol generated by the subsequent atomizer core 102. Therefore, in this embodiment, by arranging the one-way vent 104 between the distal end 1052 of the airway tube 105 and the atomizer core 102, the one-way vent 104 can block at least part of the liquid condensed from the aerosol on the tube wall of the airway tube 105 from dripping onto the atomizer core 102, thereby ensuring the taste of the aerosol.

[0040] In some embodiments, see Figure 4The atomizer 1 further comprises a sealing plug 106, the sealing plug 106 is provided with a mounting hole 1061, and the one-way vent 104 is provided at the end of the mounting hole 1061. At least a part of the airway tube 105 is plugged into the mounting hole 1061, and the airway tube 105 and the mounting hole 1061 are interference fit, so that a sealed connection is formed between the airway tube 105 and the sealing plug 106. In this embodiment, the airway tube 105 and the mounting hole 1061 are interference fit, and while the airway tube 105 and the sealing plug 106 are fixed, the sealing between the airway tube 105 and the sealing plug 106 can be improved, which is conducive to reducing the risk of aerosol leakage from the gap between the airway tube 105 and the mounting hole 1061.

[0041] In some embodiments, the one-way vent 104 is disposed at one end of the mounting hole 1061 close to the atomizer core 102 .

[0042] It is understandable that, in addition to disposing the one-way vent 104 at the end of the mounting hole 1061 , the one-way vent 104 may also be disposed inside the mounting hole 1061 .

[0043] In some embodiments, see Figure 3 The sealing plug 106 is disposed in the housing 101, the sealing plug 106 is sealedly connected to the housing 101, and the sealing plug 106 defines a part of the boundary of the liquid storage chamber 1011. In this embodiment, the sealing plug 106 is sealedly connected to the housing 101, so that the risk of the liquid matrix in the liquid storage chamber 1011 leaking from between the sealing plug 106 and the inner wall of the housing 101 can be reduced.

[0044] In some embodiments, see Figure 3 The sealing plug 106 is provided with a guide hole 1062, which provides at least a partial channel for fluid communication between the liquid storage chamber 1011 and the atomizer core 102, so that the liquid matrix in the liquid storage chamber 1011 can enter the atomizer core 102 through the guide hole 1062, so that the atomizer core 102 can atomize the liquid matrix to form aerosol.

[0045] In some embodiments, see Figure 3 There are multiple flow guide holes 1062 , all of which are disposed on the sealing plug 106 , and the multiple flow guide holes 1062 are distributed in a circular shape, and the multiple flow guide holes 1062 together provide a channel for fluid communication between the liquid storage chamber 1011 and the atomization core 102 .

[0046] In some embodiments, see Figure 3The atomizer 1 also includes a bracket 107, which supports the sealing plug 106 so that at least a portion of the sealing plug 106 is maintained in the housing 101, and the outer wall of the sealing plug 106 is maintained in contact with the inner wall of the housing 101, which is beneficial to improving the sealing between the inner wall of the housing 101 and the sealing plug 106 and reducing the risk of leakage of the liquid matrix.

[0047] In some embodiments, see Figure 3 The support 107 is provided with a first cavity 1071, and the first cavity 1071 is connected with the flow guide hole 1062 and the atomizer core 102. The liquid matrix in the liquid storage cavity 1011 can enter the atomizer core 102 through the flow guide hole 1062 and the first cavity 1071. The atomizer core 102 can be fixed to the support 107.

[0048] In some embodiments, the sealing plug 106 is integrally formed with the one-way vent 104, so there is no need to assemble the sealing plug 106 and the one-way vent 104 separately, which is conducive to improving assembly efficiency. In addition, the sealing plug 106 and the one-way vent 104 are integrally formed, and the sealing performance is strong.

[0049] In some embodiments, see Figure 3 The atomizer 1 further comprises a retaining tube 108, in which at least a portion of the atomizing core 102 is retained. The distal end 1052 of the airway tube 105 is nested and connected with the retaining tube 108, at least a portion of the sealing plug 106 is clamped between the retaining tube 108 and the airway tube 105 to provide a sealed connection between the airway tube 105 and the retaining tube 108, and at least a portion of the mounting hole 1061 is surrounded by the retaining tube 108. In this embodiment, by retaining at least a portion of the atomizer core 102 in the retaining tube 108, the atomizer core 102 can be installed and fixed, reducing the risk of the atomizer core 102 shaking; in addition, by clamping at least a portion of the sealing plug 106 between the retaining tube 108 and the airway tube 105, a sealed connection is formed between the distal end 1052 of the airway tube 105 and the retaining tube 108, thereby reducing the risk of liquid matrix entering the retaining tube 108 and the airway tube 105 from the gap between the airway tube 105 and the retaining tube 108, and reducing the risk of un-atomized liquid matrix mixing with the aerosol and affecting the taste of the aerosol.

[0050] In some embodiments, see Figure 3The atomizer 1 further includes a first liquid-conducting cotton 110, and the atomizing core 102 includes a second liquid-conducting cotton 1022 and a heating element 1023. The first liquid-conducting cotton 110 is sleeved on the outer surface of the retaining tube 108, and at least part of the first liquid-conducting cotton 110 is accommodated in the first cavity 1071. The first liquid-conducting cotton 110 can only occupy a partial space of the first cavity 1071. The first liquid-conducting cotton 110 is fluidically connected to the liquid storage cavity 1011. At least part of the liquid matrix in the liquid storage cavity 1011 flows into the first liquid-conducting cotton 110 through the guide hole 1062 on the sealing plug 106, so as to be absorbed and retained by the first liquid-conducting cotton 110. Please refer to Figure 7 The side wall of the holding tube 108 is provided with a connecting hole 1081, and the second liquid-conducting cotton 1022 is arranged in the holding tube 108, and the second liquid-conducting cotton 1022 covers the connecting hole 1081. The connecting hole 1081 can make the first liquid-conducting cotton 110 and the second liquid-conducting cotton 1022 directly abut, so that the second liquid-conducting cotton 1022 can absorb the liquid matrix on the first liquid-conducting cotton 102; or, there can be a gap between the first liquid-conducting cotton 110 and the second liquid-conducting cotton 1022, and at least part of the liquid matrix on the first liquid-conducting cotton 110 can flow into the second liquid-conducting cotton 1022 through the gap and the connecting hole 1081. The heating element 1023 is arranged in the second liquid-conducting cotton 1022, and the heating element 1023 is used to heat the liquid matrix absorbed in the second liquid-conducting cotton 1022 to atomize it into aerosol. In this embodiment, the first liquid-conducting cotton 110 is arranged between the atomizing core 102 and the liquid storage chamber 1011 to prevent the second liquid-conducting cotton 1022 from being directly immersed in the liquid matrix, thereby preventing the liquid matrix of the second liquid-conducting cotton 1022 from leaking due to excessive liquid matrix, and also preventing the heating element 1023 from frying when heated.

[0051] In some embodiments, see 3 and Figure 4 ,in, Figure 4 The straight line with an arrow in the middle is the airflow direction, and the one-way vent 104 is spaced apart from the atomizer core 102 along the airflow direction in the retaining tube 108 and the airway tube 105. Since the atomizer core 102 needs to be heated by the heating element 1023 during atomization, resulting in a high temperature of the atomizer core 102, the one-way vent 104 is spaced apart from the atomizer core 102 to reduce the risk of softening the one-way vent 104 due to heating, thereby ensuring the sealing of the one-way vent 104 when the multiple elastic membranes 1041 are closed together.

[0052] In some embodiments, see Figure 4, along the airflow direction in the holding tube 108 and the airway tube 105, the one-way vent 104 is spaced apart from the airway tube 105. In this embodiment, by arranging the one-way vent 104 and the airway tube 105 spaced apart, when the suction nozzle 103 opens the plurality of elastic membranes 1041, the risk of the tube wall of the airway tube 105 blocking the opening of the elastic membranes 1041 can be reduced, which is conducive to increasing the radial size of the opening 1042 formed when the plurality of elastic membranes 1041 are opened, and reducing the resistance during suction.

[0053] In some embodiments, see Figure 3 The atomizer 1 further includes a base 109 and two electrodes 111. The base 109 is fixed to the housing 101 and is located at one end of the bracket 107 away from the nozzle 103. At least part of the base 109 is exposed outside the housing 101. The two electrodes 111 are fixed to the base 109, and the two electrodes 111 are also electrically connected to the heating element 1023. The two electrodes 111 are exposed to the outside and are used to connect to an external power source, thereby supplying power to the heating element 1023.

[0054] In some embodiments, the atomizer 1 is further provided with an air inlet channel (not shown), one end of the air inlet channel is connected to the liquid storage chamber 1011, and the other end is connected to the outside world. When the suction nozzle 103 is sucked, the air in the liquid storage chamber 1011 can be compensated through the air inlet channel, so that the internal and external air pressures of the liquid storage chamber 1011 are kept balanced.

[0055] In the embodiment of the utility model, a liquid storage chamber 1011 is provided inside the shell 101, the atomizer core 102 is fluidically connected to the liquid storage chamber 1011, an air inlet 1031 is provided at the suction nozzle 103 for the user to inhale, and a one-way vent 104 is provided between the suction nozzle 103 and the atomizer core 102. When the suction nozzle 103 is inhaled, the one-way vent 104 is opened. At this time, the aerosol generated by the atomizer core 102 can flow from the atomizer core 102 through the one-way vent 104 into the air inlet 1031. When not inhaled, the one-way vent 104 is in a closed state, thereby reducing the leakage of the liquid matrix on the atomizer core 102 from the air inlet 1031 and reducing the risk of liquid leakage; it can also prevent the external liquid and the liquid formed in the channel between the atomizer core 102 and the suction nozzle 103 by condensation of the aerosol from entering the atomizer core 102, which helps to maintain a good atomization quality of the atomizer core 102 and is conducive to improving the user's inhalation experience.

[0056] The utility model also provides an embodiment of an atomizing device 100. Figure 3 and Figure 8 The atomization device 100 includes a power supply assembly 2 and the above-mentioned atomizer 1, the power supply assembly 2 is electrically connected to the atomization core 102, and the power supply assembly 2 is used to provide power to the atomization core 102 to atomize the liquid matrix.

[0057] Further, see 3 and Figure 8 The power supply assembly 2 is provided with two power transmission parts 201, and the atomizer 1 is detachably connected to the power supply assembly 2. When the power supply assembly 2 is connected to the atomizer 1, the two electrodes 111 are respectively in contact with the two power transmission parts 201, and the power supply assembly 2 supplies power to the heating element 1023 through the two power transmission parts 201 and the two electrodes 111, so that the liquid matrix in the atomization core 102 is atomized to form aerosol.

[0058] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
