[0002] This application claims priority to Chinese Patent Application No. 202411653652.5, filed on November 18, 2024, entitled "Atomizer and Electronic Atomizing Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of electronic atomization technology, and more particularly to an atomizer and electronic atomization device. Background Technology

[0004] An electronic atomizing device is an electronic product that produces an aerosol for a user to inhale by heating a liquid matrix, such as a liquid matrix containing nicotine. It generally consists of two parts: an atomizer and a power supply component. The atomizer stores the liquid matrix and has an atomizing core for heating the liquid matrix. The power supply component can supply power to the atomizing core to generate high temperature to heat the liquid matrix.

[0005] When the surrounding environment changes, such as during high-altitude, low-pressure transportation, a pressure difference can easily exist between the internal and external air pressure of an atomizer. This pressure difference can easily lead to leakage, especially when the atomizer is placed upside down.

[0026] In one example, one end of the first liquid guiding element is supported on the bracket, and the other end of the first liquid guiding element is disposed near the liquid storage cavity and sandwiched between the connecting tube and the bracket.

[0027] In one example, the first liquid guiding element has a tubular structure and is sleeved on the connecting tube.

[0051] As used here, the terms 'upstream' and 'downstream' describe the relative positions of components or parts of components in an electronic atomizing device in terms of the direction of the suction airflow.

[0052] Figure 1 is a schematic diagram of the electronic atomizing device provided in the embodiments of this application.

[0053] As shown in Figure 1, the electronic atomizing device 100 includes an atomizer 10 and a power supply assembly 20. The atomizer 10 is detachably connected to the power supply assembly 20, for example, by interference fit, snap-fit, or magnetic engagement. It is understood that in other examples, it is also feasible for the atomizer 10 and the power supply assembly 20 to be non-detachably connected.

[0054] Atomizer 10 is used to atomize a liquid matrix to generate an aerosol.

[0055] The power supply assembly 20 includes a battery cell 21 and a circuit 22.

[0056] The battery cell 21 provides power for operating the electronic atomizing device 100. The battery cell 21 can be a rechargeable battery cell or a disposable battery cell.

[0057] Circuit 22 can control the overall operation of the electronic atomizing device 100. Circuit 22 not only controls the operation of the battery cell 21 and the atomizer 10, but also controls the operation of other components in the electronic atomizing device 100.

[0058] Figures 2 to 5 show schematic diagrams of the structure of an atomizer according to one embodiment; the atomizer 10 in this embodiment includes:

[0059] The main housing 101 is generally cylindrical. The main housing 101 has a proximal end and a distal end opposite each other along its length. The proximal end is provided with an outlet 101a for aerosol outflow, and the distal end is configured as an end for connection with the power supply assembly 20. The distal end of the main housing 101 is open, and a removable bottom cover 102 is mounted thereon. After being connected with the bottom cover 102, the main housing 101 and the bottom cover 102 together define the housing of the atomizer 10, and the interior of the housing is hollow and contains necessary functional devices for storing and atomizing the liquid matrix; through the opening of the main housing 101, the necessary functional components can be installed inside the housing of the atomizer 10.

[0060] Please refer to Figure 6 for understanding. The bottom cover 102 has a chamber 102a, and the bottom wall of the chamber 102a has two protrusions. One of the protrusions has a through hole to form a first electrode hole 102b. The conductive part 103a of the first electrode 103 is at least partially housed in the first electrode hole 102b, and the connecting part 103b of the first electrode 103 is exposed on the outer surface of the bottom cover 102. The other protrusion has another through hole to form a second electrode hole 102c. The conductive part of the second electrode 104 is at least partially housed in the second electrode hole 102c, and the connecting part of the second electrode 104 is exposed on the outer surface of the bottom cover 102. The atomizer 10 can be electrically connected to the power supply assembly 20 through the first electrode 103 and the second electrode 104. Another protrusion is provided between the two protrusions. This other protrusion has another through hole to form an air inlet 102d. The housing has an airflow channel extending from the air inlet 102d to the air outlet 101a. Specifically, during suction, external air enters the atomizer 10 through the air inlet 102d, mixes with the generated aerosol, and then flows out of the atomizer 10 through the air outlet 101a (as shown by the dashed arrow S1 in the figure). The other protrusion also prevents the liquid matrix flowing into the chamber 102a from flowing directly out of the air inlet 102d to the power supply assembly 20.

[0061] The main shell 101 and the bottom cover 102 can be connected in a detachable manner. In a preferred embodiment, the main shell 101 is provided with a snap-fit ​​hole 101b, and the bottom cover 102 is provided with a snap-fit ​​buckle 102e that engages with the snap-fit ​​hole 101b.

[0062] The main shell 101 is provided with a notch 101c, and the bottom cover 102 is provided with a protrusion 102f. When assembling the main shell 101 and the bottom cover 102, the notch 101c can be aligned with the protrusion 102f before assembly. After assembly, the protrusion 102f is engaged in the notch 101c. The notch 101c and the protrusion 102f serve a positioning function, facilitating assembly.

[0063] The atomizer 10 housing includes a liquid storage chamber A, a second liquid guiding element 105, a heating element 106, a first lead 107, a second lead 108, a connecting pipe 109, a first liquid guiding element 110, a bracket 111, and a seal 112.

[0064] The main shell 101 also has an axially extending transmission tube 101d. The space between the outer surface of the transmission tube 101d and the inner surface of the main shell 101 forms a liquid storage cavity A for storing the liquid matrix. The hollow portion inside the transmission tube 101d forms a partial airflow channel, and one end of the transmission tube 101d is connected to the air outlet 101a, thereby transmitting the aerosol generated by the atomization of the heating element 106 to the air outlet 101a. In a preferred embodiment, the transmission tube 101d and the main shell 101 are integrally molded using a moldable material, and the resulting liquid storage cavity A is open or partially open at the distal end.

[0065] The second liquid guiding element 105 and the heating element 106 constitute an atomizing core, which atomizes the liquid matrix and generates an aerosol. Specifically, the second liquid guiding element 105 can absorb the liquid matrix and transfer it to the heating element 106. The second liquid guiding element 105 is generally tubular. It is understood that in other examples, it can also be a plate-like structure or other regular or irregular shapes. The second liquid guiding element 105 can be made of a flexible fibrous material, such as cotton fibers, non-woven fabric, or sponge. Alternatively, in other examples, the second liquid guiding element 105 can also be a rigid porous body, such as porous ceramics or porous glass. The outer surface of the second liquid guiding element 105 has a radially outwardly extending protrusion 105a.

[0066] The heating element 106 can be heated by an electric current supply and transfers heat to the liquid matrix in contact with it to heat the liquid matrix, thereby generating an aerosol. The heating element 106 is disposed close to the inner surface of the second liquid guiding element 105, and can be attached to the inner surface of the second liquid guiding element 105, or partially or completely embedded in the second liquid guiding element 105. The heating element 106 can be a resistance heating mesh, resistance heating coil, etc. The heating element 106 can be made of a material with suitable temperature coefficient of resistance characteristics, such as stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. In one example, the heating element 106 can be wound from a sheet or mesh substrate, and the wound heating element 106 is a non-closed tubular structure in the circumferential direction, that is, a tubular structure with side openings extending along the length or axial direction of the atomizer 10.

[0067] The heating element 106 has a first lead 107 and a second lead 108 welded or arranged at both ends. The first lead 107 is in contact with the conductive portion 103a of the first electrode 103 to form an electrical connection, and the second lead 108 is in contact with the conductive portion of the second electrode 104 to form an electrical connection. Specifically, the first lead 107 and the second lead 108 extend from the bottom of the bracket 111 and are bent and held on the bottom of the bracket 111. The conductive portion 103a of the first electrode 103 and the conductive portion of the second electrode 104 abut against the bottom of the bracket 111, thereby maintaining contact with the first lead 107 and the second lead 108.

[0068] Both the second liquid guiding element 105 and the heating element 106 are housed within the connecting tube 109. A first liquid guiding element 110 is disposed on the outer surface of the connecting tube 109. Specifically, the tubular first liquid guiding element 110 is sleeved on the connecting tube 109. Preferably, the inner diameter of the first liquid guiding element 110 is slightly smaller than the outer diameter of the connecting tube 109, thereby ensuring that the first liquid guiding element 110 is tightly fitted onto the connecting tube 109. The connecting tube 109 is preferably made of a thin, rigid material, such as glass fiber or stainless steel. Preferably, the atomizing core is coaxially arranged with the connecting tube 109. The side wall of the connecting pipe 109 also has a liquid guide port 109a. The first liquid guide element 110 covers the liquid guide port 109a, and a portion of the second liquid guide element 105 is exposed in the liquid storage chamber A through the liquid guide port 109a. This allows the portion of the second liquid guide element 105 to be positioned close to or in contact with the first liquid guide element 110. The liquid matrix in the liquid storage chamber A can be drawn by the first liquid guide element 110 and flow through the liquid guide port 109a into the atomizing core, i.e., drawn by the second liquid guide element 105, and atomized by the heating element 106 to generate an inhalable aerosol. Advantageously, by drawing the liquid matrix from the first liquid guide element 110 through the second liquid guide element 105, excessive or rapid transfer of the liquid matrix to the heating element 106 can be avoided.

[0069] In one example, the first liquid-guiding element 110 may be made of an elastic organic porous material, exhibiting moderate flexibility and rigidity. In this embodiment, the first liquid-guiding element 110 has an elastic modulus or stiffness smaller than that of the material of the support 111 and larger than that of the material of the second liquid-guiding element 105. Specifically, it is a rigid synthetic cotton with a Shore hardness of 20–70 A. In an alternative embodiment, the first liquid-guiding element 110 is a rigid synthetic cotton comprising oriented polyester fibers, or a rigid synthetic cotton or synthetic foam made of filamentous polyurethane, etc.

[0070] A notch 109b is also provided on the side wall of the connecting pipe 109, extending from the lower end of the connecting pipe 109 toward the upper end. The protruding portion 105a of the second liquid guiding element 105 extends into the notch 109b, thereby exposing it in the liquid storage chamber A. After assembly, the first liquid guiding element 110 maintains contact with a portion of the protruding portion 105a, thereby facilitating the second liquid guiding element 105 to absorb the liquid matrix.

[0071] It should be noted that the liquid inlet 109a and the notch groove 109b define the liquid inlet forming the connecting pipe 109, through which external liquid matrix can flow into the connecting pipe 109.

[0072] Please refer to Figures 7 and 8 for understanding. The support 111 is preferably made of a rigid material. For example, in some examples, the support 111 may be made of plastic material.

[0073] The bracket 111 and the bottom cover 102 can be connected by a snap-fit ​​connection. In a preferred embodiment, the bottom cover 102 is also provided with a snap-fit ​​hole 102g, and the bracket 111 is provided with a snap-fit ​​buckle 111a that engages with the snap-fit ​​hole 102g.

[0074] The bottom of the bracket 111 can be supported on the bottom cover 102. In a preferred embodiment, the bottom cover 102 is further provided with a support portion 102h, which is located in the chamber 102a and protrudes from the bottom wall of the chamber 102a, and the bottom of the bracket 111 can be supported on the support portion 102h.

[0075] The support 111 is roughly cylindrical in shape. External air flows into the chamber 102a through the air inlet 102d, then into the support 111, mixes with the aerosol generated by the atomizing core, flows into the transmission tube 101d, and finally flows out from the air outlet 101a.

[0076] At least a portion of the connecting tube 109 is housed within the support 111. Specifically, the inner surface of the support 111 has a boss 111b, which extends radially inward from the inner surface of the support 111. The upper end of the connecting tube 109 is connected to the transmission tube 101d, for example, the upper end of the connecting tube 109 is sleeved on the transmission tube 101d; the lower end of the connecting tube 109 is inserted into the connecting tube 109 and abuts against the boss 111b. Furthermore, the boss 111b also has a support portion 111c extending axially toward the air outlet 101a, which supports the second liquid guiding element 105 when the lower end of the connecting tube 109 is inserted into the connecting tube 109.

[0077] The sidewall of the support 111 has a first opening 111d and a second opening 111e. At least a portion of the first liquid guiding element 110 is housed within the support 111. Specifically, a support portion 111f is provided near the first opening 111d and / or the second opening 111e. The lower end of the first liquid guiding element 110 can be inserted into the support 111 and supported on the support portion 111f. The upper end of the first liquid guiding element 110 is positioned near the liquid storage chamber A and sandwiched between the upper end of the support 111 and the connecting pipe 109. In this way, the liquid matrix in the liquid storage chamber A can be drawn in by the upper end of the first liquid guiding element 110 and flow towards the lower end of the first liquid guiding element 110.

[0078] Please refer to Figure 9 for understanding. The seal 112 can be made of a flexible material, such as silicone. The seal 112 is cylindrical. The lower end of the seal 112 is fitted onto the bottom cover 102, and the end face of the lower end of the seal 112 abuts against the step 102i of the bottom cover 102. The bracket 111 is at least partially housed within the seal 112; in a preferred embodiment, the bracket 111 is located within the seal 112. When the main housing 101 and the bottom cover 102 are connected, part of the seal 112 is sandwiched between the main housing 101 and the bottom cover 102, and part of the seal 112 is sandwiched between the main housing 101 and the bracket 111, thereby achieving a seal.

[0079] Furthermore, the outer surface of the seal 112 has one or more protruding sealing rings 112a, which can better form a seal between the main housing 101 and the bottom cover 102 and / or between the main housing 101 and the bracket 111.

[0080] Furthermore, the inner surface of the seal 112 has a step 112b. When the bracket 111 is assembled into the seal 112, the upper end face of the bracket 111 can abut against the step 112b, thus axially limiting the bracket 111 and achieving the effect of proper assembly.

[0081] Due to the presence of the first opening 111d and the second opening 111e, a buffer cavity B is formed between the outer surface of the portion of the first liquid guiding element 110 located within the support 111 and the inner surface of the seal 112. Specifically, the outer surface of the portion of the first liquid guiding element 110 located within the support 111, the inner surface of the seal 112, and the support 111 together define the buffer cavity B, which is arranged around the first liquid guiding element 110.

[0082] A venting groove 111g is provided on the bracket 111. The distance between the end of the venting groove 111g located in the buffer chamber B and the connecting pipe 109 is smaller than the distance between the end of the venting groove 111g located in the buffer chamber B and the seal 112. The buffer chamber B can communicate with the airflow channel inside the housing through the venting groove 111g, thereby communicating with the outside of the atomizer 10. The buffer chamber B can also communicate with the liquid storage chamber A through the ventilation channel C between the bracket 111 and the seal 112. For example, a groove 111h is provided on the outer surface of the part of the bracket 111 that contacts the seal 112. After assembly, the groove 111h defines at least a portion of the boundary of the ventilation channel C.

[0083] Please refer to Figure 4 for understanding. The distance between the outer surface of the first liquid guiding element 110 located inside the bracket 111 and the inner surface of the seal 112 is H1. Generally, H1 is between 0.3mm and 2mm, or between 0.3mm and 1.5mm, or between 0.3mm and 1mm, or between 0.3mm and 0.8mm.

[0084] The venting groove 111g is located at one end of the buffer cavity B and protrudes from the bottom of the buffer cavity B. Specifically, the distance between the end of the venting groove 111g located in the buffer cavity B and the bottom of the buffer cavity B is H2. Generally, H2 is between 0.5mm and 2mm, or between 0.5mm and 1.5mm, or between 0.5mm and 1mm.

[0085] The distance between the bottom of the buffer chamber B and the liquid inlet (i.e., the liquid guide port 109a or the notch groove 109b) is H3. Generally, H3 is between 0.5mm and 2mm, or between 0.5mm and 1.5mm, or between 0.5mm and 1mm. As can be seen from the foregoing description and the attached figure, H3 is greater than H2.

[0086] The distance between the top of the buffer chamber B and the liquid inlet (i.e., the liquid guide port 109a or the notch groove 109b) is H4. Generally, H4 is between 0.5mm and 2mm, or between 0.5mm and 1.5mm, or between 0.5mm and 1mm.

[0087] Please refer to Figures 3-4 for understanding. When the atomizer 10 is in the upright position, the air pressure balance between the liquid storage chamber A and the outside can be achieved through the air exchange channel C, the buffer chamber B, and the ventilation groove 111g. The buffer chamber B can temporarily store the liquid matrix that overflows from the liquid storage chamber A. Due to the above-mentioned distance setting, the liquid matrix temporarily stored in the buffer chamber B will not leak out through the ventilation groove 111g. Even if a small part of the liquid matrix leaks out through the ventilation groove 111g, the leaked liquid matrix will be temporarily stored in the chamber 102a of the bottom cover 102 and will not flow out from the air inlet 102d to the power supply component 20. For example, when the air pressure in the storage chamber A is low due to the consumption of the liquid matrix, external air can be replenished to the storage chamber A through the venting channel 111g, the buffer chamber B, and the ventilation channel C, thereby achieving air pressure balance between the storage chamber A and the outside. When changes in the external environment lead to low air pressure (such as in a high-altitude, low-pressure transportation environment), the storage chamber A can also achieve air pressure balance with the outside through the ventilation channel C, the buffer chamber B, and the venting channel 111g. At this time, the liquid matrix overflowing from the ventilation channel C or the first liquid guiding element 110 can be temporarily stored in the buffer chamber B.

[0088] Please refer to Figure 10 for understanding. When the atomizer 10 is in the inverted state, when the external environment changes and the air pressure is low (such as in a high-altitude, low-pressure transportation environment), the liquid matrix in the storage chamber A can overflow from the ventilation channel C or the first liquid guiding element 110. The overflowed liquid matrix can be temporarily stored in the buffer chamber B. Due to the above-mentioned distance setting, the liquid matrix temporarily stored in the buffer chamber B will not leak out through the ventilation groove 111g. When the external environment recovers, the liquid matrix temporarily stored in the buffer chamber B can flow back to the storage chamber A through the ventilation channel C or the first liquid guiding element 110.

[0089] Please refer to Figure 11 for understanding. When the atomizer 10 is in the side-mounted state, when the external environment changes and the air pressure is low (such as in a high-altitude, low-pressure transportation environment), the liquid matrix in the liquid storage chamber A can overflow from the ventilation channel C or the first liquid guiding element 110. The overflowed liquid matrix can be temporarily stored in the buffer chamber B. Due to the above-mentioned distance setting, the liquid matrix temporarily stored in the buffer chamber B will not leak out through the ventilation groove 111g.

[0090] The above analysis shows that the atomizer 10 can ensure that the liquid matrix will not leak out when placed in any direction, through the buffer chamber B.
