Description

[Technical Field]

[0001] This application relates to the field of atomization technology, and more particularly to an atomizer and an electronic atomization device. [Background Technology]

[0002] Traditional tobacco products (e.g., cigarettes, cigars, etc.) produce tobacco smoke through combustion during use. Existing technologies offer alternatives to these traditional tobacco products by releasing compounds through heating without combustion. Examples of such products are electronic atomizing devices, which typically contain an atomizable liquid matrix and atomizing components for atomizing the liquid matrix to produce inhalable vapor or aerosol. The liquid matrix may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin).

[0003] As the liquid matrix in the storage chamber is consumed, the air volume in the storage chamber increases, which in turn leads to a decrease in air pressure in the storage chamber and the generation of negative pressure. In order to ensure that the liquid matrix in the storage chamber can continue to flow smoothly to the atomizing component, an air channel needs to be set up to replenish air in the storage chamber to alleviate the negative pressure in the storage chamber. [Utility Model Content]

[0004] This application provides an atomizer that can improve the sealing effect while forming an air passage.

[0005] At least one embodiment of this application provides an atomizer, including:

[0006] The liquid storage chamber is used to store atomizable liquid matrix;

[0007] Atomizing component for atomizing the liquid matrix to generate an aerosol;

[0008] An atomizing tube is used to house the atomizing component, and the tube wall of the atomizing tube has a liquid guiding hole that connects the atomizing component and the liquid storage chamber.

[0009] A sealing element for providing a seal to the liquid storage cavity;

[0010] The sealing element includes a sealing rib that surrounds the atomizing tube and elastically abuts against the atomizing tube. The sealing rib is constructed in a spiral shape and defines a spiral airflow channel with the outer wall of the atomizing tube. The airflow channel has an air inlet port and an air outlet port. The air inlet port is in communication with the outside air, and the air outlet port is in communication with the liquid storage chamber.

[0011] In one embodiment, the seal defines a insertion groove for insertion of the atomizing tube, the insertion groove having an open end and a bottom wall disposed opposite each other, and a side wall extending between the open end and the bottom wall, the sealing rib being disposed on the side wall of the insertion groove.

[0012] In one embodiment, the atomizing tube is supported on the bottom wall of the insertion slot.

[0013] In one embodiment, the bottom wall has a vent hole that connects the air inlet port to the outside air.

[0014] In one embodiment, the projection of the air intake port on the bottom wall is spaced apart from the vent hole.

[0015] In one embodiment, the cross-section of the insertion slot is circular, and the projection of the air inlet port on the bottom wall maintains a 180° arc with respect to the vent hole.

[0016] In one embodiment, the airflow channel extends to the opening end, and the end face of the opening end is provided with a venting groove that connects the liquid storage chamber and the air outlet port.

[0017] In one embodiment, the sealing rib includes a gradient section extending into the vent groove, the protrusion height of which gradually decreases along the transmission direction of the airflow channel.

[0018] In one embodiment, the atomizer further includes a base for providing support for the seal, the base having an electrical connection portion electrically connected to the atomizing assembly, the electrical connection portion being used for electrical connection to a power supply assembly.

[0019] In one embodiment, the atomizer further includes a limiting member supported on the seal, the limiting member being used to limit the seal in the axial direction of the atomizer.

[0020] This application also provides at least one electronic atomizing device, including the atomizer described in the above embodiments, and a power supply component for electrically connecting to the atomizer and providing electrical power to the atomizer.

[0021] The atomizer provided in the above embodiments, by setting spiral sealing ribs on the sealing element, defines an airflow channel between the sealing ribs and the outer wall of the atomizing tube. Outside air can enter the liquid storage chamber through this airflow channel, thereby replenishing the liquid storage chamber with air and maintaining the air pressure balance within the liquid storage chamber. Furthermore, by setting spiral sealing ribs, multiple seals can be provided, effectively preventing leakage of the liquid matrix in the liquid storage chamber. [Attached Image Description]

[0037] One embodiment of this application provides an atomizer 100 for atomizing a liquid matrix to generate an aerosol, such as... Figure 1 and Figure 2 As shown, the atomizer 100 includes a housing 10 and a base 20. The housing 10 has a first end 11 and a second end 12 opposite to each other along its length. The first end 11 forms an air outlet 111 for aerosol to escape from the atomizer 100. The second end 12 is open. At least a portion of the base 20 extends into the housing 10 through the opening of the second end 12 to support the components in the housing 10.

[0038] A liquid storage chamber 13 is formed in the housing 10. The liquid storage chamber 13 is used to store the atomizable liquid matrix. A gas guide tube 14 extends longitudinally in the liquid storage chamber 13. The gas guide tube 14 is connected to the gas outlet 111. The gas guide tube 14 is used to transport the atomized aerosol to the gas outlet 111.

[0039] In some embodiments, such as Figure 1 As shown, the first end 11 is configured as a flat suction nozzle shape, so that the user can directly perform suction at the first end 11.

[0040] In some embodiments, the atomizer 100 can be installed in a power supply assembly for use with it. The power supply assembly is provided with a mouthpiece for the user to inhale. When the atomizer 100 is installed in the power supply assembly, the air outlet 111 is connected to the mouthpiece of the power supply assembly so as to transfer the aerosol escaping from the air outlet 111 to the mouthpiece of the power supply assembly.

[0041] like Figure 2 As shown, the atomizer 100 also includes a seal 30, which is supported on the base 20. The seal 30 is used to seal the liquid storage chamber 13 to prevent the liquid matrix in the liquid storage chamber 13 from leaking through the assembly gap between the housing 10 and the base 20. The seal 30 can be made of latex materials such as silicone, rubber, or latex, and thus the seal 30 can achieve the seal of the liquid storage chamber 13 by elastically abutting against the inner wall of the housing 10.

[0042] Please continue reading. Figure 2 The atomizer 100 also includes an atomizing tube 40, in which an atomizing component 50 is disposed. The atomizing component 50 includes a liquid guiding element 51 and a heating element 52 coupled to the liquid guiding element 51. A liquid guiding hole 41 is formed in the wall of the atomizing tube 40, connecting the liquid storage chamber 13 and the liquid guiding element 51. The liquid guiding element 51 can then transfer the liquid matrix in the liquid storage chamber 13 to the heating element 52, which can then heat and atomize the liquid matrix to generate an aerosol. Figure 2 The liquid transport path R1 is shown in the diagram.

[0043] One end of the air guide tube 14 is connected to the air outlet 111, and the other end extends into the atomizing tube 40, so that the aerosol generated by the atomizing component can enter the air guide tube 14 and flow along the air guide tube 14 to the air outlet 111.

[0044] In some embodiments, the liquid guiding element 51 may be formed of a porous material, such as cotton fiber, nonwoven fabric, fiberglass rope, porous ceramic, or porous glass, so that the liquid guiding element 50 can absorb and transfer the liquid matrix through its internal pores or microporous structure. Correspondingly, the heating element 52 may be attached to the liquid guiding element 51 by means of printing, deposition, sintering, or physical assembly, or wound around the liquid guiding element 51.

[0045] like Figure 2 As shown, the base 20 is provided with an air inlet 21, which provides an airflow inlet for outside air to enter the atomizer 100. When the user uses the atomizer 100 for inhalation, a negative pressure is generated inside the atomizer 100, which in turn forces outside air to enter the atomizer 100 through the air inlet 21. Then, the outside air further enters the atomizing tube 40, and carries the aerosol released in the atomizing tube 40 into the air guide tube 14. Finally, the air guide tube 14 transmits the air to the outlet 111. Figure 2 The airflow transmission path R2 is shown in the diagram.

[0046] And, in some embodiments, such as Figure 3 As shown, the base 20 is also provided with electrode holes, and electrode posts 22, which serve as electrical connection parts, are held in the electrode holes. The electrode posts 22 are electrically connected to the electrode leads 53 of the atomizing assembly 50. Part of the electrode posts 22 is exposed on the outer surface of the base 20, so that when the atomizer 100 is installed in the power supply assembly, the exposed part of the electrode posts 22 can be electrically connected to the power supply assembly, thereby enabling the power supply assembly to provide the electrical energy required for atomization to the atomizing assembly 50.

[0047] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the sealing member 30 is provided with a insertion groove 31 for the atomizing tube 40 to be inserted. The insertion groove 31 has an open end 311 for the atomizing tube 40 to enter, a bottom wall 312 opposite to the open end 311, and a side wall 313 extending between the open end 311 and the bottom wall 312. The sealing element 30 also includes a sealing rib 314 disposed on the side wall 313. The sealing rib 314 is constructed in a spiral shape. When the atomizing tube 40 is inserted into the insertion groove 31, the sealing rib 314 surrounds the periphery of the atomizing tube 40 and elastically abuts against the atomizing tube 40, thereby defining a spiral airflow channel 315 between the sealing rib 314 and the outer wall of the atomizing tube 40. The airflow channel 315 has an air inlet port 3151 and an air outlet port 3152. The air inlet port 3151 communicates with the outside air. For example, the air inlet port 3151 can communicate with the air inlet hole 21 to achieve communication with the outside air, while the air outlet port 3152 communicates with the liquid storage chamber 13.

[0048] It should be noted that the air inlet port 3151 refers to the position where the spiral sealing rib 314 begins to be wound, while the air outlet port 3152 refers to the position where the spiral sealing rib 314 ends to be wound.

[0049] In this way, when negative pressure is generated in the liquid storage chamber 13 due to the consumption of the liquid matrix, outside air can be guided into the liquid storage chamber 13 through the airflow channel 315, thereby replenishing the air in the liquid storage chamber 13, relieving the negative pressure in the liquid storage chamber 13, and maintaining the air pressure balance in the liquid storage chamber 13. In addition, when the spiral sealing ribs 314 elastically abut against the atomizing tube 40, multiple seals can be provided to effectively prevent leakage of the liquid matrix in the liquid storage chamber 13.

[0050] In some embodiments, such as Figure 2 and Figure 6As shown, when the atomizing tube 40 is inserted into the insertion slot 31, the atomizing tube 40 is supported on the bottom wall 312 of the insertion slot 31, which can limit the atomizing tube 40 and facilitate the assembly of the atomizing tube 40.

[0051] In some embodiments, such as Figure 5 and Figure 7 As shown, the bottom wall 312 is provided with a vent 3121 that connects the air inlet port 3151 and the outside air. When a negative pressure is generated in the liquid storage chamber 13, the outside air can enter the spiral airflow channel 315 through the vent 3121 and then enter the liquid storage chamber 13 to replenish the air in the liquid storage chamber 13.

[0052] In some embodiments, such as Figure 5 As shown, the projection of the air inlet port 3151 on the bottom wall 312 is spaced apart from the vent 3121, so that the vent 3121 is not located directly below the air inlet port 3151. Therefore, when the air pressure in the liquid storage chamber 13 increases, the liquid matrix can be prevented from flowing along the airflow channel 315 into the vent 3121 and leaking out of the atomizer 100.

[0053] In some embodiments, such as Figure 5 As shown, the cross-section of the insertion slot 31 is circular, and the projection of the air inlet port 3151 on the bottom wall 312 maintains a 180° arc with the vent hole 3121, so that the vent hole 3121 is as far away from the air inlet port 3151 as possible, in order to further prevent the liquid matrix from flowing along the airflow channel 315 into the vent hole 3121 and leaking out of the atomizer 100 when the air pressure in the liquid storage chamber 13 increases.

[0054] In some embodiments, such as Figure 6 , Figure 7 and Figure 8 As shown, the airflow channel 315 extends to the opening end 311 of the insertion slot 31, and a venting groove 3111 is provided on the end face of the opening end 311 of the insertion slot 31 to connect the liquid storage chamber 13 and the air outlet port 3152. Thus, the air escaping from the air outlet port 3152 can be guided into the liquid storage chamber 13 through the venting groove 3111.

[0055] And, in some embodiments, such as Figure 8 As shown, in order to enable the airflow channel 315 to extend to the opening end 311 and escape from the vent groove 3111 at the opening end 311, the sealing rib 314 also includes a gradient section 3141. The gradient section 3141 extends to the vent groove 3111, and the protrusion height of the gradient section 3141 gradually decreases along the transmission direction of the airflow channel 315.

[0056] In some embodiments, such as Figure 2As shown, the atomizer 100 also includes a limiting member 60 supported on the seal 30. The limiting member 60 is fixedly connected to the housing 10, and the seal 30 is clamped between the limiting member 60 and the base 20. The limiting member 60 is used to axially limit the seal 30 to prevent the seal 30 from shifting in the axial direction of the atomizer 100, thereby reducing the sealing effect.

[0057] One embodiment of this application also provides an electronic atomizing device 200, which can be found in [reference]. Figure 9 As shown, it includes an atomizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply assembly 200 that supplies power to the atomizer 100.

[0058] In an alternative implementation, for example Figure 9 As shown, the power supply assembly 200 includes a receiving cavity 210 disposed at one end along the length direction for receiving and accommodating at least a portion of the atomizer 100, and an electrical contact 220 at least partially exposed on the surface of the receiving cavity 210 for forming an electrical connection with the electrode post 22 of the atomizer 100 to supply power to the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated within the power supply assembly 200.

[0059] A sealing element 230 is provided inside the power supply assembly 200, and the sealing element 230 divides at least a portion of the internal space of the power supply assembly 200 to form the receiving cavity 210. Figure 9 In the preferred embodiment shown, the seal 230 is configured to extend along the cross-sectional direction of the power assembly 200, and is preferably made of a flexible material such as silicone, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving cavity 210 from flowing into components such as the controller 240 and sensor 250 inside the power assembly 200.

[0060] exist Figure 9 In the preferred embodiment shown, the power supply assembly 200 further includes a battery cell 260 for power supply located at the other end of the receiving cavity 210 along its length; and a controller 240 disposed between the battery cell 260 and the receiving cavity 210, the controller 240 being operable to guide current between the battery cell 260 and the electrical contact 220.

[0061] In use, the power supply assembly 200 includes a sensor 250 for sensing the suction airflow generated when the user inhales through the air outlet 111 of the atomizer 100, and 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.

[0062] Further in Figure 9 In the preferred embodiment shown, the power supply assembly 200 has a charging unit 270 at the other end away from the receiving cavity 210 for charging the battery cell 260.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; under the concept of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this application as described above, which are not provided in detail for the sake of brevity; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
