Description

Technical Field

[0001] This application relates to the field of atomization technology, and particularly to a mouthpiece assembly, an atomizer, and an electronic atomization device having the mouthpiece assembly.

Background Art

[0002] Traditional tobacco products (such as cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. There are already products in the prior art that release compounds without burning by heating to replace these traditional tobacco products. Examples of such products are electronic atomization devices, which typically include a heating element and a liquid storage cavity for storing a liquid matrix. The liquid matrix is heated by the heating element to cause atomization, thereby generating inhalable vapor or aerosol. The liquid matrix may contain nicotine and / or flavoring agents and / or aerosol-forming substances (such as glycerol).

[0003] Known electronic atomization devices generally include a porous ceramic body with a large number of micropores inside. The porous ceramic body usually has a liquid absorption surface for absorbing the liquid matrix and an opposite atomization surface. A heating element for atomizing the liquid matrix is provided on the atomization surface. The liquid matrix absorbed on the liquid absorption surface can be transferred to the atomization surface through the microporous structure inside the porous ceramic body, and the heating element can heat and atomize the liquid matrix to generate aerosol.

[0004] Such electronic atomization devices usually also have a ventilation channel, which is used to supply air to the liquid storage cavity to maintain the air pressure balance inside and outside the liquid storage cavity when the liquid matrix in the liquid storage cavity is consumed. During the user's suction process, external air can enter the liquid storage cavity through this ventilation channel and generate bubbles. The generated bubbles are likely to accumulate on the liquid absorption surface. Excessive accumulation of bubbles on the liquid absorption surface will hinder the liquid absorption surface from continuing to absorb the liquid matrix, thus easily causing insufficient supply of the liquid matrix to the heating element and resulting in the problem of dry burning of the heating element.

In the description of this application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0046] An embodiment of the present application provides an atomizer 100, as Figure 1 and Figure 2 shown, the atomizer 100 includes a mouthpiece assembly 10, a liquid storage part 20, a base 30 and an atomization element 40. The mouthpiece assembly 10 and the base 30 are respectively fixedly installed at both ends of the liquid storage part 20 to form the housing of the atomizer 100. The atomization element 40 is arranged in the liquid storage part 20 for atomizing a liquid matrix to generate an aerosol.

[0047] Inside the liquid storage part 20, there is a hollow cylindrical structure 21 extending axially. The hollow area 211 of the hollow cylindrical structure 21 serves as the liquid storage chamber of the atomizer 100 for storing liquid matrices such as atomizable liquid medicine or e-cigarette atomization liquid. When the liquid stored in the liquid storage chamber 211 is liquid medicine, the atomizer 100 can be used as a medical atomizer for treating respiratory diseases; when the liquid stored in the liquid storage chamber 211 is e-cigarette atomization liquid, the atomizer 100 can be used as an e-cigarette.

[0048] As Figure 2 , Figure 3 and Figure 4 shown, the liquid storage part 20 has opposite proximal end 22 and distal end 23. The mouthpiece assembly 10 is arranged at the proximal end 22 of the liquid storage part 20, and the base 30 is arranged at the distal end 23 of the liquid storage part 20. The proximal end 22 is provided with a first opening 221 communicating with the liquid storage chamber 211. The first opening 221 serves as a liquid injection port for injecting the liquid matrix into the liquid storage chamber 211. The proximal end 22 is also provided with a first seal 50 for sealing the first opening 221. The base 30 extends at least partially into the liquid storage part 20 through the open end at the distal end 23, thereby providing support for the components inside the liquid storage part 20. The hollow cylindrical structure 21 and the inner wall of the liquid storage part 20 define a first air flow channel 24 and a second air flow channel 25. The aerosol generated by the atomization element 40 atomizing the liquid matrix can flow into the mouthpiece 10 through the first air flow channel 24 and the second air flow channel 25. The user can inhale the aerosol through the air outlet 11 of the mouthpiece part 10.

[0049] As Figure 5 shown, the atomization element 40 includes a first capillary core element 41 and a heating element 42 combined on the first capillary core element 41. The first capillary core element 41 can be made of hard capillary structures such as porous ceramics, porous glass ceramics, and porous glass, and has a large number of microporous structures inside. The first capillary core element 41 can be generally but not limited to a block structure in the embodiment. According to the usage situation, it includes a liquid absorption surface 411 and an atomization surface 412 arranged oppositely along the length direction of the atomizer 100, that is, Figure 4 the upper and lower surfaces of the block-shaped first capillary core element 41 in. The liquid absorption surface 411 faces the liquid outlet 2111 for sucking the liquid matrix, and the heating element 42 is combined on the atomization surface 412 for heating and atomizing the liquid matrix. The liquid matrix can flow from the liquid outlet 2111 to the liquid absorption surface 411 and flow to the atomization surface 412 through the internal microporous structure of the first capillary core element 41.

[0050] The heating element 42 is preferably formed on the atomizing surface 412 by mixing a conductive raw material powder with a printing aid to form a slurry, printing it in a suitable pattern, and then sintering it, so that all or most of its surface is tightly bonded to the atomizing surface 412, having effects such as high atomization efficiency, less heat loss, preventing dry burning or greatly reducing dry burning. In some embodiments, the heating element 42 can adopt a variety of other structural forms. For example, the heating element 42 can be a sheet-shaped heating element with a specific pattern bonded to the atomizing surface 412, or other forms such as a heating mesh, a disc-shaped heating element formed by spiraling a heating wire, a heating film, etc. In some examples, the specific pattern can be a serpentine shape. In some embodiments, suitable materials that the heating element 42 can adopt include materials such as nickel, iron, stainless steel, nickel-iron alloy, nickel-chromium alloy, iron-chromium-aluminum alloy, or titanium metal. Therefore, when the liquid matrix is transferred to the atomizing surface 412, the heating element 42 on the atomizing surface 412 can heat and atomize the liquid matrix, and release the aerosol generated after atomization from the atomizing surface 412.

[0051] As Figure 2 and Figure 3 shown, the liquid storage cavity 211 includes a side wall 2112 and a bottom wall 2113. The bottom wall 2113 is provided with a second opening 2111 communicating with the liquid storage cavity 211. From Figure 2 and Figure 3 it can be seen that the second opening 2111 is provided at the distal end 23 of the liquid storage part 20. The second opening 2111 serves as an outlet for the liquid matrix in the liquid storage cavity 211 to flow to the atomizing element 40. An extension wall 2114 extends along the length direction of the atomizer 100 from the bottom wall 2113. The extension wall 2114 and the bottom wall 2113 define a first accommodation chamber 212, and the atomizing element 40 is accommodated in the first accommodation chamber 212. To prevent the liquid matrix from leaking through the assembly gap between the atomizing element 40 and the inner wall of the first accommodation chamber 212, a second seal 60 is provided between the atomizing element 40 and the first accommodation chamber 212. The second seal 60 forms a second accommodation chamber, and the atomizing element 40 is tightly fitted in the second accommodation chamber. The second seal 60 can be a soft rubber part such as silica gel or rubber, so that the second seal 60 can be clamped between the atomizing element 40 and the inner wall of the second accommodation chamber 212, thereby sealing the second seal 60 between the atomizing element 40 and the inner wall of the first accommodation chamber 212. The second seal 60 is formed with a through hole for the liquid matrix to flow through, and the through hole communicates with the outlet 2111. The liquid matrix flows to the atomizing element 40 through the outlet 2111 and the through hole.

[0052] As Figure 2As shown, an air inlet 31 and an electrode hole are provided on a base 30. A conductive electrode 32 is inserted into the electrode hole. One end of the conductive electrode 32 is exposed outside the housing of the atomizer 100 to facilitate electrical connection with a power supply mechanism used in conjunction with the atomizer 100, and the other end extends to the atomizing surface 412 of the first capillary core element 41 to facilitate electrical connection with a heating element 42 on the atomizing surface 412. Thus, through the conductive electrode 32, the power supply mechanism can supply the electrical energy required for heating to the heating element 42 of the atomizer 100. It can be understood that the conductive electrode 32 includes two electrode columns that guide current as positive and negative electrodes. The end of the conductive electrode 32 abuts against the atomizing element 40 to support it and position it in the first accommodation chamber 212 described above.

[0053] Please continue to refer to Figure 2 , a third seal 70 is supported on the base 30. The third seal 70 can be a flexible material such as silica gel or rubber. The third seal 70 is in interference fit with the inner wall of the liquid storage part 20 to seal the distal end 23 of the liquid storage part 20. The third seal 70 is disposed opposite to the atomizing element 40 and defines an atomizing chamber 413. The aerosol generated by heating and atomizing the liquid matrix by the atomizing element 40 is released therein.

[0054] When the user uses the atomizer 100 to suck, external cold air enters the atomizing chamber 413 and mixes with the high-temperature aerosol in the atomizing chamber 413. Part of the high-temperature aerosol will condense to form condensate and drip down when encountering the external cold air. The seal formed by the third seal 70 can prevent the dripping condensate from leaking out from the distal end 23 of the liquid storage part 20.

[0055] The air inlet hole 31 provides an air flow inlet for external air to enter the atomizer 100. An air vent hole 71 is formed on the third seal 70. The air vent hole 71 communicates the air inlet hole 31 and the atomizing chamber 413. Thus, when the user sucks, a negative pressure is generated inside the atomizing chamber 413, prompting the external air to flow through the air inlet hole 31 and the air vent hole 71 into the atomizing chamber 413, and then carry the aerosol in the atomizing chamber 413 into the first air flow channel 24 and the second air flow channel 25, and then flow through the first air flow channel 24 and the second air flow channel 25 into the mouthpiece 10, and finally escape from the air outlet hole 11 of the mouthpiece 10 for the user to inhale, thereby forming a complete air flow path of the atomizer 100, as Figure 2 shown by the arrow route R in

[0056] Please continue to refer to Figure 6 , Figure 7 , Figure 8 and Figure 10, an exhaust hole 51 is formed in the first seal 50. The exhaust hole 51 is used to allow the air in the liquid storage chamber 211 to be discharged through the exhaust hole 51 when the first seal 50 is assembled to the liquid storage part 20 to seal the first opening 221, so as to avoid the air in the liquid storage chamber 211 being squeezed during the assembly process of the first seal 50, which may cause the liquid matrix in the liquid storage chamber 211 to leak.

[0057] The nozzle assembly 10 includes a tubular body 12 extending into the exhaust hole 51. The tubular body 12 is in interference fit with the exhaust hole 51 to seal the exhaust hole 51. The tubular body 12 is hollow, and thus a second capillary core element 80 can be arranged in the tubular body 12, so that at least a part of the second capillary core element 80 closes the first opening 221. The second capillary core element 80 can be assembled in the tubular body 12 by being in interference fit with the inner wall of the tubular body 12. A first notch 121 extending to the liquid storage chamber 211 is formed in the tube wall of the tubular body 12 along the longitudinal direction. Since the first seal 50 and the second capillary core element 80 are respectively located on both sides of the first notch 121, the first seal 50, the first notch 121 and the second capillary core element 80 can define a capillary channel 1211. That is to say, at least a part of the capillary channel 1211 is defined by the outer surface of the second capillary core element 80 and the inner surface of the exhaust hole 51.

[0058] The capillary channel 1211 communicates the liquid storage chamber 211 with the external air to provide an air path for the external air to enter the liquid storage chamber 211, so as to balance the air pressure between the liquid storage chamber 211 and the external air, and avoid the generation of negative pressure in the liquid storage chamber 211 due to the consumption of the liquid matrix in the liquid storage chamber 211, which may cause the atomizing element 40 to dry burn due to insufficient liquid supply.

[0059] The capillary channel 1211 communicates with the second capillary core element 80, and a part of the liquid matrix is stored on the second capillary core element 80. When the user does not inhale the aerosol using the atomizer 100, the air pressure between the liquid storage chamber 211 and the external air is in a balanced state. The liquid matrix stored on the second capillary core element 80 flows into the capillary channel 1211 under the capillary force of the capillary channel 1211, and then seals the air path for the external air to enter the liquid storage chamber 211, so as to avoid the liquid matrix in the liquid storage chamber 211 from leaking out through this air path.

[0060] When the user inhales the aerosol using the atomizer 100, the atomizing element 40 heats the liquid matrix to generate the aerosol, and the liquid matrix in the liquid storage cavity 211 is immediately consumed, resulting in an increase in the gas volume of the liquid storage cavity 211, and further resulting in a decrease in the air pressure in the liquid storage cavity 211. At this time, the air pressure of the external air is greater than the air pressure in the liquid storage cavity 211, that is, there is an air pressure difference between the external air and the liquid storage cavity 211. Under the action of this air pressure difference, the liquid matrix in the capillary channel 1211 will flow back to the second capillary core element 80, and then open the air path for the external air to enter the liquid storage cavity 211. The external air can enter the liquid storage cavity 211 to balance the air pressure between the liquid storage cavity 211 and the external air, so that the liquid matrix in the liquid storage cavity 211 can continue to flow smoothly to the atomizing element 40.

[0061] The second capillary core element 80 is made of a porous material, such as any one of flexible cotton fibers, non-woven fabrics or fiberglass ropes; or any one of porous ceramics, porous glass ceramics, porous glass, etc. Therefore, the second capillary core element 80 can have water absorption and thus absorb and hold the liquid matrix. In a further preferred embodiment, the second capillary core element 80 is made of a flexible cotton fiber material, so that more liquid matrix can be absorbed in the second capillary core element 80, and the liquid matrix can flow smoothly back and forth between the capillary channel 1211 and the second capillary core element 80 under the action of capillary force and air pressure difference.

[0062] Alternatively, in some embodiments, the air path for air interaction between the liquid storage cavity 211 and the external air can also form a capillary channel by the microporous structure or voids inside the second capillary core element 80 itself, and the liquid storage cavity 211 and the external air achieve air exchange through the capillary channel inside the second capillary core element 80.

[0063] In this embodiment, the second capillary core element 80 is disposed at the proximal end of the liquid storage component 20, so that the second capillary core element 80 is located above the liquid level of the liquid matrix. Furthermore, the external air enters the liquid storage cavity 211 from above the liquid level of the liquid matrix and through the capillary channel defined by the second capillary core element 80 or formed by itself. This method can avoid the bubbles formed in the liquid matrix when the external air enters the liquid matrix from gathering on the first capillary core element 41 compared with the external air entering the liquid storage cavity from below the liquid level of the liquid matrix, and further avoid dry burning of the heating element 42 due to insufficient liquid supply.

[0064] In some embodiments, such as Figure 11As shown, the second wick element 80 includes a first surface 81 facing the liquid storage chamber 211 and a second surface 82 opposite to the first surface 81. The first surface 81 communicates with the liquid storage chamber 211, and the second surface 82 communicates with the air outlet 11 of the nozzle assembly 10. Thus, external air can enter the liquid storage chamber 211 through the air outlet 11 and the second wick element 80.

[0065] Moreover, in some embodiments, the capillary channel 1211 extends to the first surface 81 so that the liquid matrix flowing back from the capillary channel 1211 to the second wick element 80 adheres to and hangs on the first surface 81. Thus, when the air pressure in the liquid storage chamber 211 and the air pressure of the external air are restored to balance, the liquid matrix hanging on the first surface 81 can smoothly flow back into the capillary channel 1211 under the capillary force of the capillary channel 1211.

[0066] In some embodiments, as Figure 2 and Figure 6 shown, a first abutting portion 122 extends laterally on the inner wall of the tubular body 12, and a second abutting portion 52 is formed on the first seal 50. The first abutting portion 122 and the second abutting portion 52 are arranged opposite to each other in the longitudinal direction, so that the second wick element 80 is abutted between the first abutting portion 122 and the second abutting portion 52 in the longitudinal direction, and thus the second wick element 80 is further held in the tubular body 12.

[0067] Furthermore, in some embodiments, when the second wick element 80 is made of flexible cotton fiber, the second wick element 80 abutted between the first abutting portion 122 and the second abutting portion 52 has a thickness of 1.2 mm to 2 mm, so that the second wick element 80 can absorb and hold an appropriate amount of liquid matrix. Thus, when the air pressure in the liquid storage chamber 211 and the air pressure of the external air reach balance, an appropriate amount of liquid matrix on the second wick element 80 can flow into the capillary channel 1211 to achieve the sealing of the air path.

[0068] In some embodiments, as Figure 6 and Figure 11As shown, the first seal 50 can be any one of soft rubber components such as silica gel, rubber or latex. When the first seal 50 is assembled in the first opening 221, the first seal 50 elastically abuts against the inner wall of the liquid storage chamber 211 to seal the first opening 221. At least one second notch 123 spaced from the first notch 121 is formed in the tube wall of the tubular body 12. At the same time, a groove 53 is formed on the outer surface of the first seal 50. The groove 53 communicates with the inner wall of the liquid storage chamber 211 and the second notch 123 to guide the liquid matrix adhering to the inner wall of the liquid storage chamber 211 to the second wick element 80, so as to supplement the liquid matrix to the second wick element 80. It is easy to understand that at this time, the second wick element 80 is made of a porous material, and the liquid matrix adhering to the inner wall of the liquid storage chamber 211 is absorbed through the water absorption of the porous material 80 through the groove 53. Further, in a preferred embodiment, the second wick element 80 is made of flexible cotton fibers.

[0069] And, in some implementations, such as Figure 10 As shown, the second notch 123 includes a plurality of second notches 123 arranged symmetrically with respect to the first notch 121 to guide more liquid matrix adhering to the inner wall of the liquid storage chamber 211 to the second wick element 80.

[0070] In some embodiments, such as Figure 7 As shown, an air guiding channel 54 is formed between the tubular body 12 and the first seal 50. The air guiding channel 54 communicates with the capillary channel 1211 and the external air. The inner diameter of the air guiding channel 54 is larger than the inner diameter of the capillary channel 1211. By providing the air guiding channel 54 with a larger inner diameter, the external air can be smoothly introduced into the capillary channel 1211.

[0071] Further, in some embodiments, such as Figure 7 As shown, the bottom wall 1212 of the first notch 121 is inclined, so that an inclined section 55 is formed between the air guiding channel 54 and the capillary channel 1211. After the external air enters the air guiding channel 55, the external air can be further smoothly guided into the capillary channel 1211 through the inclined section 55.

[0072] It should be noted that the capillary channel 1211 is not limited to being formed by the structures described in the above embodiments. In some other embodiments, other structural methods can also be used to form the capillary channel 1211, as long as the air pressures in the liquid storage cavity 211 and the external air are in a balanced state, and the liquid matrix stored on the second capillary core element 80 flows into the capillary channel 1211 under the capillary force of the capillary channel 1211, thereby sealing the air path for the external air to enter the liquid storage cavity 211; and when the air pressure of the external air is greater than the air pressure in the liquid storage cavity 211, under the action of this pressure difference, the liquid matrix in the capillary channel 1211 will flow back to the second capillary core element 80, thereby opening the air path for the external air to enter the liquid storage cavity 211.

[0073] An embodiment of the present application also provides an electronic atomization device 200, which can be seen Figure 11 as shown, including an atomizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply component 200 that powers the atomizer 100.

[0074] In an alternative embodiment, for example Figure 11 as shown, the power supply component 200 includes a receiving cavity 210 provided at one end along the length direction for receiving and accommodating at least a part of the atomizer 100, and electrical contacts 220 at least partially exposed on the surface of the receiving cavity 210, which are used to form an electrical connection with the electrode 32 of the atomizer 100 and thereby power the atomizer 100 when at least a part of the atomizer 100 is received and accommodated within the power supply component 200.

[0075] A seal 230 is provided within the power supply component 200, and at least a part of the internal space of the power supply component 200 is separated by this seal 230 to form the above-mentioned receiving cavity 210. In Figure 11 the preferred embodiment shown, the seal 230 is configured to extend in the cross-sectional direction of the power supply component 200, and preferably is made of a flexible material such as silicone, thereby preventing the liquid matrix that seeps from the atomizer 100 to the receiving cavity 210 from flowing to components such as the controller 240 and the sensor 250 inside the power supply component 200.

[0076] In Figure 11 the preferred embodiment shown, the power supply component 200 further includes a power supply cell 260 at the other end along the length direction away from the receiving cavity 210; and a controller 240 provided between the power supply cell 260 and the receiving cavity 210, and the controller 240 can operably guide current between the power supply cell 260 and the electrical contacts 220.

[0077] In use, the power supply component 200 includes a sensor 250 for sensing the suction airflow generated when the user sucks through the air outlet 111 of the atomizer 100. Then, the controller 240 controls the battery cell 260 to output current to the atomizer 100 according to the detection signal of the sensor 250.

[0078] Further, in Figure 11 In the preferred embodiment shown, the power supply component 200 is provided with a charging interface 270 at the other end facing away from the receiving cavity 210 for charging the battery cell 260.
