[0002] The atomizer has a liquid storage chamber, an atomizing channel, and an atomizing core. The liquid storage chamber is used to hold the atomized liquid, and the atomizing core connects the liquid storage chamber and the atomizing channel.

[0046] Example 1

[0047] Combine Figures 1 to 3, the present application provides an atomizer. The atomizer includes an atomizing body 100, an atomizing base 200, an atomizing core 300, an atomizing electrode 500 and a first sealing member 410. The atomizing body 100 has a liquid storage chamber 101 and an atomizing channel 102 that are connected. The atomizing base 200 is installed on the atomizing body 100, and the atomizing base 200 has a mounting blind hole 210 and a connecting through hole 220. The connecting through hole 220 has a first orifice 221 and a second orifice 222. The first orifice 221 is located on the hole wall of the mounting blind hole 210, and the second orifice 222 is connected to the atomizing channel 102. The atomizing core 300 is installed in the atomizing channel 102, and the atomizing core 300 is provided with a pin 301, which extends to the mounting blind hole 210 through the second orifice 222 and the first orifice 221. The first sealing member 410 covers the first opening 221 and the pin 301 located in the first opening 221. The atomizing electrode 500 is installed in the mounting blind hole 210. The atomizing electrode 500 abuts and connects with the pin 301 located in the mounting blind hole 210. The atomizing electrode 500 is configured to elastically compress the first sealing member 410 against the first opening 221.

[0048] The atomization channel 102 is connected to the liquid storage chamber 101, allowing the atomized liquid in the liquid storage chamber 101 to enter the atomization channel 102 and be atomized by the atomization core 300. In some embodiments, the liquid storage chamber 101 is used to store an aerosol-generating substrate. The aerosol-generating substrate can be a liquid aerosol-generating substrate or a solid aerosol-generating substrate, which is not specifically limited here.

[0049] In this embodiment, the first sealing member 410 covers the first opening 221 of the connecting through-hole 220. The first sealing member 410 is elastically compressed against the first opening 221 under the pressure of the atomizing electrode 500, closely fitting around the periphery of the first opening 221 and wrapping around the pin 301 located at the first opening 221, thereby forming a reliable sealing barrier and effectively blocking the atomized liquid in the atomizing channel 102 from leaking outward through the connecting through-hole 220. Under the covering and pressure of the first sealing member 410, the pin 301 maintains a stable position within the mounting blind hole 210, which helps to improve the contact reliability between the pin 301 and the atomizing electrode 500, thereby solving the technical problems of poor sealing and contact in existing atomizers, thereby improving the sealing performance of the atomizer and improving the operating reliability of the atomizer.

[0050] In addition, the first sealing member 410 is elastic, and the atomizing electrode 500 can adjust the specific installation position of the atomizing electrode 500 in the mounting blind hole 210 by adjusting the pressing force on the first sealing member 410, so as to be compatible with the manufacturing tolerances of the atomizing electrode 500 and / or the atomizing base 200, until the atomizing electrode 500 is adjusted to reliably abut the pin 301. Furthermore, the operator can flexibly replace the first sealing member 410 of different sizes to adapt to the manufacturing tolerances of the atomizing electrode 500 and / or the mounting blind hole 210, without having to reprocess the atomizing electrode 500 and the mounting blind hole 210, thereby reducing the processing precision requirements of the atomizing electrode 500 and the mounting blind hole 210, and ensuring that the atomizing electrode 500 is stably installed in the mounting blind hole 210 and maintains good contact with the pin 301.

[0051] In some embodiments, combined Figure 2 There are two mounting blind holes 210 and two atomizing electrodes 500. Each atomizing electrode 500 is mounted in one mounting blind hole 210. Each atomizing electrode 500 is connected to the atomizing core 300 through a pin 301. One of the atomizing electrodes 500 is used to connect to the external positive electrode, and the other atomizing electrode 500 is used to connect to the external negative electrode, so that the current passes through the atomizing electrode 500 connected to the positive electrode, the atomizing core 300 and the atomizing electrode 500 connected to the negative electrode in sequence to form a circuit.

[0052] In some embodiments, combined Figure 2 and Figure 3 The mounting blind hole 210 includes a first hole section 211 and a second hole section 212 distributed from the inside to the outside. The aperture of the second hole section 212 is larger than the aperture of the first hole section 211, and a first step wall 213 is formed between the second hole section 212 and the first hole section 211. The first orifice 221 is located at the first step wall 213. Based on this, when the first sealing member 410 covers the first orifice 221, the first sealing member 410 is stably supported by the first step wall 213, and the first sealing member 410 is stably positioned at the first orifice 221, maintaining a good seal on the first orifice 221, preventing the first sealing member 410 from opening the first orifice 221 due to displacement, thereby enhancing the sealing reliability of the atomizer.

[0053] In one embodiment, the combination Figure 3 and Figure 5The atomizing electrode 500 includes a first rod portion 510 and a second rod portion 520 connected to each other. The first rod portion 510 is installed in the first hole section 211, and the second rod portion 520 is installed in the second hole section 212. The first rod portion 510 and the second rod portion 520 are respectively installed in hole sections with different hole diameters. The second rod portion 520 abuts against the first step wall 213 and cannot enter the first hole section 211. This ensures that the atomizing electrode 500 is unidirectionally limited in its length direction, improves the positional stability of the atomizing electrode 500, ensures that the atomizing electrode 500 is reliably positioned to press the first sealing member 410, and reliably maintains good contact with the pin 301.

[0054] Specifically, the diameter of the second rod portion 520 is greater than the diameter of the first rod portion 510, and a second step wall is formed between the second rod portion 520 and the first rod portion 510. The second step wall and the first step wall 213 fit together, thereby increasing the support area and installation strength of the atomizing electrode 500 in the installation blind hole 210.

[0055] In one embodiment, the combination Figure 3 The first seal 410 is clamped and fixed between the second rod portion 520 and the wall of the second hole section 212, thereby limiting the radial position of the first seal 410 in the second hole section 212, preventing the first seal 410 from deviating in the radial direction of the second hole section 212, and ensuring that the first seal 410 can stably seal the first orifice 221. In addition, the first seal 410 fits tightly against the second rod portion 520 and the wall of the second hole section 212, effectively blocking the connection between the installation blind hole 210 and the outside, thereby sealing the installation blind hole 210. The first seal 410 simultaneously clamps the second rod portion 520 in a counter-action manner, ensuring the stable position of the atomizing electrode 500 in the radial direction of the second hole section 212, reducing the loosening or displacement of the atomizing electrode 500 due to vibration or external force, and ensuring reliable contact between the atomizing electrode 500 and the pin 301.

[0056] In one embodiment, the combination Figure 3 The pin 301 extends through the first opening 221 to the first step wall 213, and part of the pin 301 is clamped and fixed between the first step wall 213 and the second rod portion 520. On the one hand, this ensures that the position of the pin 301 in the length direction of the blind hole 210 is stable. On the other hand, it ensures that the pin 301 clamped by the second rod portion 520 is in good contact with the atomizing electrode 500, with a large contact area and stable contact.

[0057] In one embodiment, the combination Figure 2 and Figure 3The pin 301 extends through the first step wall 213 to the first hole section 211, and the first rod portion 510 abuts against the pin 301 located in the first hole section 211, thereby increasing the contact surface between the atomizing electrode 500 and the pin 301, and increasing the length of the pin 301 in the mounting blind hole 210, thereby improving the contact area between the pin 301 and the atomizing electrode 500, and helping to maintain good contact between the pin 301 and the atomizing electrode 500.

[0058] Specifically, the pin 301 abuts against the atomizing electrode 500 at the first step wall 213 and the hole wall of the first hole section 211, which increases the number of contact surfaces between the pin 301 and the atomizing electrode 500 and increases the contact area between the two, which is conducive to good contact between the two.

[0059] In one embodiment, the combination Figure 3 The pin 301 located in the first hole section 211 is clamped and fixed between the first rod portion 510 and the hole wall of the first hole section 211, thereby improving the position stability of the pin 301 in the first hole section 211 and effectively preventing the pin 301 from loosening or deflecting due to factors such as vibration and impact during use, thereby improving the contact reliability between the atomizing electrode 500 and the pin 301.

[0060] In one embodiment, the combination Figure 3 The first hole section 211 includes, from the inside out, a first sub-hole 214 and a second sub-hole 215. The diameter of the second sub-hole 215 is larger than that of the second sub-hole 215. The first rod portion 510 is interference fit within the first sub-hole 214, and the first sealing member 410 is clamped and fixed between the first rod portion 510 and the hole wall of the second sub-hole 215. The interference fit between the first rod portion 510 and the first sub-hole 214 improves the positional security of the atomizing electrode 500 within the blind hole 210. The gap between the first rod portion 510 and the second sub-hole 215 can accommodate the pin 301, preventing it from being crushed, while effectively ensuring that the pin 301 is clamped and fixed between the first rod portion 510 and the hole wall of the second sub-hole 215.

[0061] In some embodiments, combined Figure 3 and Figure 5The atomizing electrode 500 further includes a third rod portion 530, which is located on the side of the second rod portion 520 away from the first rod portion 510. The diameter of the third rod portion 530 is larger than that of the second rod portion 520. The first sealing member 410 is clamped and fixed between the pin 301 and the third rod portion 530, so that the first sealing member 410 is fixed in position along the length of the atomizing electrode 500. On the one hand, the first sealing member 410 can maintain a fixed position and seal the first orifice 221, and on the other hand, it can further compress the pin 301, improving the position stability of the pin 301. The third rod portion 530 can also abut and fix the pin 301, enhancing the contact stability between the pin 301 and the atomizing electrode 500.

[0062] In one embodiment, the combination Figure 3 The mounting blind hole 210 further includes a third hole segment 216. The third hole segment 216 is located on a side of the second hole segment 212 away from the first hole segment 211. The third rod portion 530 is mounted in the third hole segment 216. The third hole segment 216 strengthens the circumferential limitation of the third rod portion 530, thereby improving the position reliability of the third rod portion 530.

[0063] Specifically, the end of the third rod portion 530 is lower than or flush with the opening of the third hole section 216 , so as to prevent the third rod portion 530 from protruding from the third hole section 216 and prevent the third rod portion 530 from wearing or rubbing against external structures.

[0064] In one embodiment, the combination Figure 3 The diameter of the third rod portion 530 is greater than the diameter of the second hole section 212, and the third rod portion 530 cannot enter the second hole section 212. The third rod portion 530 can stably abut the end surface of the second hole section 212 and cannot further compress the first sealing member 410, thereby achieving precise control of the compression amount of the first sealing member 410, which is conducive to precise control of the sealing strength of the first sealing member 410 on the first orifice 221.

[0065] Specifically, the initial thickness of the first seal 410 is 1.5 to 2.5 times the length of the second rod portion 520. When the atomizing electrode 500 is installed, the first seal 410 is compressed between the first step wall 213 and the third rod portion 530. The installed thickness of the compressed first seal 410 is equal to the length of the second rod portion 520. Since the initial thickness of the first seal 410 is 1.5 to 2.5 times the length of the second rod portion 520, the compression rate of the first seal 410 along the length of the mounting blind hole 210 after installation is between 33% and 60%, thereby preventing damage to the first seal 410 due to excessive compression or reduced sealing performance due to insufficient compression.

[0066] In one embodiment, the combination Figure 2 and Figure 5The first sealing member 410 is a sealing ring, which is sleeved on the atomizing electrode 500 and surrounds the atomizing electrode 500 for a circle to achieve circumferential sealing of the atomizing electrode 500. At the same time, even if the sealing ring rotates around the atomizing electrode 500, the sealing ring still seals the first orifice 221, thereby reducing the requirements for the alignment installation of the first orifice 221 during assembly of the sealing ring and simplifying the assembly difficulty.

[0067] Specifically, the first sealing member 410 is disposed around the second rod portion 520 .

[0068] In one embodiment, the combination Figure 3 The compression rate of the first seal 410 in the radial direction of the atomizing electrode 500 is 40% to 60%, allowing the first seal 410 to fit more closely to the atomizing electrode 500 and the wall of the mounting blind hole 210, thereby improving the sealing performance of the mounting blind hole 210. At the same time, the compression rate is controlled within 40% to 60% to avoid damage to the first seal 410 due to excessive compression, and to avoid insufficient compression that may result in poor sealing performance. A moderate compression rate helps maintain the elasticity of the first seal 410, allowing it to deform appropriately when subjected to pressure, thereby better filling the gap between the first sealing opening 221 and the pin 301 and improving the sealing effect.

[0069] In this embodiment, the first sealing member 410 is pressed by the atomizing electrode 500 to fit the first opening 221 , thereby sealing the first opening 221 .

[0070] In one embodiment, the atomizing electrode 500 can be positioned directly opposite the first opening 221, pressing the first sealing member 410 against the first opening 221. For example, Figure 3 The first sealing member 410 is clamped and fixed between the third rod portion 530 , the pin 301 and the first step wall 213 .

[0071] In one embodiment, the atomizing electrode 500 may not press the first sealing member 410 directly against the first opening 221. The first sealing member 410 elastically bulges directly against the first opening 221 due to elastic deformation to seal the first opening 221. For example, Figure 3 The first seal 410 is clamped and fixed between the second rod portion 520 and the wall of the second hole section 212. The first seal 410 is compressed in the radial direction of the second hole section 212, thereby elastically protruding in the axial direction of the second hole section 212, and tightly fitting the first hole 221 and the pin 301 located in the first hole 221.

[0072] It should be noted that the first orifice 221 can be located on the first step wall 213 of the second hole segment 212, on other side walls of the second hole segment 212, or on the wall of the first hole segment 211, without specific limitation herein. The mounting blind hole 210 can include only the first hole segment 211, or both the first hole segment 211 and the second hole segment 212, or both the first hole segment 211, the second hole segment 212, and the third hole segment 216, i.e., the specific shape of the mounting blind hole 210 is not limited.

[0073] In some embodiments, the atomizing electrode 500 is riveted into the mounting blind hole 210. It is understood that in other embodiments, the atomizing electrode 500 can be fixed in the mounting blind hole 210 by bonding, clamping, or fastener connection, which is not limited here.

[0074] In one embodiment, the combination Figure 2 and Figure 4 The end of the atomizing base 200 close to the atomizing channel 102 is sealed and sleeved with the atomizing core 300, and the sleeve connection is conducive to increasing the contact area. The mutual nesting reduces the risk of the atomized liquid bypassing the end and leaking between the atomizing base 200 and the atomizing core 300.

[0075] Specifically, the atomizer base 200 and the atomizer core 300 are fixed by snapping together, that is, the atomizer base 200 and the atomizer core 300 are fixed by means of a clamping block and a clamping slot. The clamping block and the clamping slot increase the clamping area of ​​the atomizer base 200 and the atomizer core 300, and the tortuous clamping surface makes it difficult for the atomized liquid to bypass the clamping block and the clamping slot to cause leakage.

[0076] In one embodiment, the combination Figure 2 and Figure 4 The end of the atomizing base 200 away from the atomizing channel 102 is sealed and socketed with the atomizing body 100, and the socketing is conducive to increasing the contact area. The mutual nesting reduces the risk of the atomized liquid bypassing the end and leaking between the atomizing base 200 and the atomizing body 100, effectively preventing the atomized liquid from leaking at the connection between the atomizing base 200 and the atomizing body 100.

[0077] Specifically, combined Figure 2A second sealing member 420 is provided between the atomizing base 200 and the atomizing body 100. The second sealing member 420 increases the sealing performance of the connection between the atomizing base 200 and the atomizing body 100. Optionally, the second sealing member 420 is compressed and arranged between the outer wall of the atomizing base 200 and the inner wall of the atomizing body 100. Optionally, a limiting groove is provided on the outer wall of the atomizing base 200, and the second sealing member 420 is installed in the limiting groove to improve the positional stability of the second sealing member 420. Optionally, the groove depth of the limiting groove is 40% to 60% of the initial width of the second sealing member 420, limiting the compression rate of the second sealing ring to 40% to 60%.

[0078] In some embodiments, combined Figure 4 and Figure 5 The side of the atomizing channel 102 has a first through hole 103, which connects the atomizing channel 102 and the liquid storage chamber 101. The first through hole 103 serves as a liquid passage, allowing the atomized liquid in the liquid storage chamber 101 to enter the atomizing channel 102, and then be heated by the atomizing core 300 in the atomizing channel 102 to be atomized.

[0079] In some embodiments, combined Figures 3 to 5 The atomizer core 300 includes an atomizer bracket 310, a first liquid guide member 320, a second liquid guide member 330 and a heating element 340. The atomizer bracket 310 is installed on the atomizer channel 102. The side wall of the atomizer bracket 310 has a second through hole 311. The first liquid guide member 320 covers the first through hole 103. The first liquid guide member 320 is arranged between the side of the atomizer channel 102 and the atomizer bracket 310. The second liquid guide member 330 covers the second through hole 311. The heating element 340 is installed on the side of the first liquid guide member 320 away from the second through hole 311. The heating element 340 is connected to the pin 301. The first liquid guiding member 320 and the second liquid guiding member 330 cover the first through hole 103 and the second through hole 311 respectively, so that the communication between the liquid storage chamber 101 and the atomization channel 102 is not limited to direct penetration, so that the atomized liquid slowly enters the atomization channel 102, the flow rate is uniform and controllable, and the situation of local concentration being too high or too low is avoided, thereby improving the uniformity and effect of atomization.

[0080] Specifically, the first liquid guide 320 and the second liquid guide 330 can be made of porous adsorption materials, such as absorbent cotton, which is not specifically limited here. Specifically, the heating element 340 can be a heating mesh sleeve, a spiral heating wire, or a plurality of connected circumferentially arranged heating mesh sheets, which is not specifically limited here.

[0081] In some embodiments, combined Figure 2 and Figure 4The atomizer body 100 includes an atomizer housing 110, a channel cover 120, a base 130, and a support frame 140. The channel cover 120, the base 130, and the support frame 140 are installed inside the atomizer housing 110. One end of the support frame 140 is connected to the channel cover 120, and the other end of the support frame 140 is connected to the base 130. The interior of the channel cover 120 forms an atomization channel 102. The outer wall of the channel cover 120, the inner wall of the atomizer housing 110, and the support frame 140 surround the liquid storage chamber 101.

[0082] Specifically, a third sealing member 430 is provided between the channel cover body 120 and the atomizing housing 110 to improve the sealing performance of the connection between the two.

[0083] Specifically, the support frame 140 is sleeved in the fourth sealing member 440 , and the support frame 140 is sealedly connected to the channel cover 120 , the inner wall of the atomizing housing 110 , and the base 130 through the fourth sealing member 440 .

[0084] Specifically, the atomizer body 100 further includes a suction nozzle 150, which is sleeved onto the end of the atomizer housing 110 away from the base 130. The suction nozzle 150 has a suction port that is connected to the atomization channel 102 for inhaling aerosol in the atomization channel 102. Optionally, the suction nozzle 150 is configured to be detachably mounted on the atomizer housing 110 to facilitate replacement of the suction nozzle 150; alternatively, the suction nozzle 150 and the atomizer housing 110 are integrally formed, welded, or fixed by fasteners, which is not specifically limited here.

[0085] Specifically, the atomizing housing 110 has a liquid injection port, and an openable and closable liquid plug 160 is installed at the liquid injection port to facilitate adding atomized liquid to the liquid storage chamber 101. The base 130 is used to install the atomizing base 200.

[0086] In one embodiment, an air inlet channel 104 is formed in the atomizing housing 110 , and the air inlet channel 104 is communicated with the atomizing channel 102 . The atomizing housing 110 has an air inlet port communicated with the air inlet channel 104 , so that external air can enter the air inlet channel 104 .

[0087] Specifically, there are many feasible ways for the air inlet channel 104 to be in the atomizer housing 110, such as the air inlet channel 104 being integrally formed in the atomizer housing 110, or the air inlet channel 104 being assembled from multiple sections and then installed in the atomizer housing 110, which is not specifically limited here.

[0088] Specifically, the air inlet channel 104 is connected to the atomizing channel 102 at one end away from the suction nozzle 150. The atomizer of the present application adopts a top air intake method. When the aerosol in the atomizer is inhaled, the external gas enters the air inlet channel 104 through the air inlet located at the top, then enters the bottom of the atomizing channel 102, passes through the atomizing channel 102 and enters the suction nozzle 150 to be extracted by the user. Since the atomizer adopts a top air intake method, the atomized liquid in the atomizer will not leak from the air inlet. It should be noted that the top and bottom in the present application are described when the atomizer is in use. When in use, the suction nozzle 150 is at the top of the atomizing housing 110.

[0089] Furthermore, to accommodate the needs of different users, the air intake size of the air inlet passage 104 is adjustable. For example, the atomizer includes an air regulating valve plate 170, which is mounted at the air inlet. The air regulating valve plate 170 can slide or rotate relative to the atomizer housing 110 to adjust the opening and closing area of ​​the air inlet. The air regulating valve plate 170 occupies a small space, making the atomizer structure more compact.

[0090] Specifically, a liquid absorption member 180 is provided between the air inlet channel 104 and the atomizing channel 102 to prevent the atomized liquid in the atomizing channel 102 from leaking to the outside of the atomizing housing 110 through the air inlet channel 104. The atomized liquid can be adsorbed by the liquid absorption member 180 to prevent the atomized liquid from flowing out of the atomizer. Optionally, the liquid absorption member 180 uses liquid absorption cotton. Optionally, the base 130 has a liquid accumulation groove for collecting the atomized liquid. The fourth sealing member 440 is located on the upper side of the liquid accumulation groove. The lower end of the atomizing core 300 is mounted on the base 130 and is sealed with the fourth sealing member 440. The fourth sealing member 440 can be made of silicone. The space between the fourth sealing member 440 and the base 130 forms a connecting section of the air inlet channel 104 for gas to enter the atomizing channel 102.
