[0057] With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0058] As shown in the drawings, Figures 1 to 4 To solve the problem that the user cannot inhale when using the atomizer or the atomizer wick is blocked due to insufficient heat dissipation during adjustment of the opening degree of the air inlet in the related art, the present application provides an air resistance adjusting assembly 10, which is used for installing in an atomizer to adjust the air resistance of the atomizer. The air resistance adjusting assembly 10 comprises a base 1 and an adjusting part 2.

[0059] The base 1 is formed with an air passage, and the air passage has at least one air inlet 111.

[0060] It should be noted that the air passage can be linear or curved, and specifically, the present application does not limit the specific shape of the air passage. The air passage can have one air inlet 111, two air inlets 111, three air inlets 111 or even more, and specifically, the number of air inlets 111 can be set as needed, and the present application does not limit this.

[0061] The adjusting part 2 is movably installed on the base 1, and in the moving state of the adjusting part 2, the adjusting part 2 can block part of the at least one air inlet 111 or stagger the at least one air inlet 111.

[0062] It should be noted that the adjusting part 2 can be movably installed on the base 1 in various ways, for example, in an embodiment, the adjusting part 2 can be rotatably installed on the base 1 about an axis. In another embodiment, the adjusting part 2 can also be slidably installed on the base 1 in a certain direction. Specifically, the present application does not limit this.

[0063] The adjusting part 2 can block part of the at least one air inlet 111 or stagger the air inlet 111. Specifically, when the adjusting part 2 blocks part of the at least one air inlet 111, the part of the air inlet 111 that is not blocked can be used for gas flow, and when the adjusting part 2 staggers the air inlet 111, the air inlet 111 is completely exposed, and gas can also enter from the air inlet 111.

[0064] In the suction resistance adjusting assembly 10, the adjusting part 2 can block part of or misalign the at least one air inlet 111 when the adjusting part 2 moves. In this way, no matter how the adjusting part 2 moves, the at least one air inlet 111 can have an exposed part, so that gas can enter from the exposed part of the at least one air inlet 111, realizing that the suction resistance adjusting assembly 10 can ensure a continuous airflow through the atomizer no matter how the user adjusts the suction resistance, avoiding the user from inhaling when using the atomizer, and improving the atomization effect and user experience. In addition, since the suction resistance adjusting assembly 10 can ensure a continuous airflow through the atomizer, the atomizer can be properly cooled, avoiding problems such as a burnt wick. Since no matter how the adjusting part 2 moves, the at least one air inlet 111 can have an exposed part, this improves the fault tolerance of the suction resistance adjusting assembly 10, so that even if the adjusting part 2 moves due to a misoperation, the at least one air inlet 111 can have an exposed part to ensure the airflow through the atomizer, ensuring the normal operation of the atomizer. In addition, the adjusting part 2 can be driven to move to change the area of the adjusting part 2 blocking the at least one air inlet 111, so as to realize adjusting the size of the air intake according to the needs while ensuring the air intake of the atomizer, ensuring that the atomization effect of the atomizer meets the user's needs, and improving the user experience of the atomizer.

[0065] In an embodiment, the exposed area of the at least one air inlet 111 is greater than or equal to 1.65mm 2 , so that the minimum air intake of the air passage can be ensured, thereby ensuring that the atomizer can generate stable smoke to meet the basic use needs of the user. If the exposed area of the at least one air inlet 111 is less than 1.65mm 2 , it may cause insufficient airflow, and the user may have difficulty inhaling when using the atomizer. In addition, if the exposed area of the at least one air inlet 111 is less than 1.65mm 2 , it will affect the heating efficiency of the atomizer and the generation of smoke, and there are problems such as poor heat dissipation of the atomizer. The air inlet 111 area with the exposed area of the at least one air inlet 111 being greater than or equal to 1.65mm 2 can effectively avoid this problem, ensuring that the atomizer can maintain effective heat dissipation and stable performance under various use conditions. When the exposed area of the at least one air inlet 111 is greater than or equal to 1.65mm 2 , the gas entering from the exposed part of the at least one air inlet 111 can make the user feel smooth airflow during use, reducing the feeling of having a large resistance during use, thereby improving the user experience. When the exposed area of the at least one air inlet 111 is greater than or equal to 1.65mm 2When the at least one air inlet 111 is exposed, the gas entering from the exposed part of the at least one air inlet 111 can ensure that the heat and smoke inside the atomizer can be smoothly discharged, and the risk of failure caused by poor air flow can be reduced.

[0066] Specifically, the area exposed by the at least one air inlet 111 can be 1.65mm 2 , 1.68mm 2 , 1.7mm 2 , 1.72mm 2 , 1.75mm 2 , 1.78mm 2 , 1.8mm 2 , 1.83mm 2 , 1.85mm 2 , 1.86mm 2 , 1.87mm 2 , 1.9mm 2 , 2mm 2 , 2.1mm 2 , 2.3mm 2 or 2.36mm 2 , and specifically, the area exposed by the at least one air inlet 111 can be set as needed, which is not limited in the present application.

[0067] In an embodiment, the at least one air inlet 111 includes a first air inlet 1111 and a second air inlet 1112.

[0068] It should be noted that the shapes of the first air inlet 1111 and the second air inlet 1112 are various, for example, the first air inlet 1111 and the second air inlet 1112 can be circular holes, oval holes, rectangular holes, square holes or other polygonal holes. Specifically, the shapes of the first air inlet 1111 and the second air inlet 1112 can be set as needed, which is not limited in the present application.

[0069] The air channel includes a first air channel and a second air channel arranged at intervals, the first air inlet 1111 is located in the first air channel, and the second air inlet 1112 is located in the second air channel, so that air can be respectively introduced through the first air channel and the second air channel, thereby achieving efficient air intake. The first air channel and the second air channel can also avoid the situation that when one of the first air channel and the second air channel is blocked, the other one can introduce air, thereby ensuring that the atomizer can work normally.

[0070] Referring to Figures 2 to 4In the case of the adjustment part 2 moving, the adjustment part 2 can block or disengage the first air inlet 1111, so that the adjustment part 2 can change the size of the blocked first air inlet 1111, thereby adjusting the air intake of the first air inlet 1111. Specifically, when the adjustment part 2 moves to block the first air inlet 1111, the first air inlet 1111 is completely blocked, and at this time the first air inlet 1111 cannot intake air. Then drive the adjustment part 2 to move, so that the adjustment part 2 gradually increases the part of the first air inlet 1111 exposed, and finally the adjustment part 2 is disengaged from the first air inlet 1111, at this time the first air inlet 1111 is completely exposed, and at this time the air intake of the first air inlet 1111 is the largest. This design realizes the continuous adjustment range of the first air inlet 1111 from complete closing to complete opening, so that the air intake of the first air inlet 1111 can be accurately adjusted according to the actual demand.

[0071] Referring to Figures 2 to 4 , the adjustment part 2 can block part of the second air inlet 1112 or disengage the second air inlet 1112, so that the adjustment part 2 can adjust the size of the exposed part of the second air inlet 1112 under the premise of ensuring that the second air inlet 1112 is partially exposed to facilitate air intake, thereby adjusting the size of the air intake of the second air inlet 1112 while ensuring that the second air inlet 1112 can intake air. Specifically, when the adjustment part 2 blocks part of the second air inlet 1112, the second air inlet 1112 is partially exposed, so that air can enter from the exposed part of the second air inlet 1112, and at this time the air intake of the second air inlet 1112 is the smallest. Then drive the adjustment part 2 to move, so that the adjustment part 2 can gradually increase the part of the second air inlet 1112 exposed, and finally the second air inlet 1112 is disengaged from the adjustment part 2, at this time the second air inlet 1112 is completely exposed, so that the air intake of the second air inlet 1112 is the largest. This design ensures that the second air inlet 1112 can adjust the air intake according to the need while ensuring that it can intake air.

[0072] In addition, by adjusting the air intake of the first air inlet 1111 and the second air inlet 1112, the suction resistance adjustment assembly 10 can have multiple operating modes. When the suction resistance adjustment assembly 10 is used in an atomizer, the atomizer can gradually increase the air intake according to the need while ensuring the minimum air intake of the atomizer, so that the atomizer can provide more choices for the user to meet the user's experience.

[0073] In an embodiment, the adjusting part 2 comprises a ring-shaped body 21, a first blocking block 22 and a second blocking block 23. The ring-shaped body 21 is rotationally connected to the base 1 along the axial direction of the ring-shaped body 21. In this way, the requirement for the movement space of the ring-shaped body 21 is reduced, the structure of the resistance adjusting assembly 10 is more compact, and the volume of the resistance adjusting assembly 10 is reduced. The first blocking block 22 is connected to the ring-shaped body 21, the second blocking block 23 is connected to the ring-shaped body 21, and the first blocking block 22 and the second blocking block 23 are arranged at intervals along the circumferential direction of the ring-shaped body 21. When the ring-shaped body 21 rotates, the first blocking block 22 can block or stagger the first air inlet 1111, and the second blocking block 23 can block part of the second air inlet 1112 or stagger the second air inlet 1112. In this way, when the adjusting part 2 rotates, the first blocking block 22 can adjust the air intake of the first air inlet 1111, and the second blocking block 23 can adjust the air intake of the second air inlet 1112 while ensuring that the second air inlet 1112 can intake air. The structure is simple and easy to operate.

[0074] It should be noted that the cross-sectional shape of the first blocking block 22 and the second blocking block 23 along the axial direction of the ring-shaped body 21 can be various, for example, the cross-sectional shape of the first blocking block 22 and the second blocking block 23 can be rectangular, square, semicircular or trapezoidal, etc. Specifically, in the embodiment of the present application, the cross-sectional shape of the first blocking block 22 and the second blocking block 23 away from the ring-shaped body 21 is arc-shaped. Specifically, the cross-sectional shape of the first blocking block 22 and the second blocking block 23 along the axial direction of the ring-shaped body 21 can be set as needed, which is not limited in the present application.

[0075] Specifically, the first blocking block 22 and the second blocking block 23 are protruded on the side of the ring-shaped body 21. In this way, the ring-shaped body 21, the first blocking block 22 and the second blocking block 23 are designed integrally, the number of connecting parts is reduced, and the structure of the entire adjusting part 2 is more compact.

[0076] Referring to Figure 1In an embodiment, the limiting structure can be provided, and the limiting structure includes the limiting protrusion 14 protruding from the base, the limiting protrusion 14 has the first limiting surface 141 and the second limiting surface 142 oppositely and spaced apart along the circumference of the annular body 21, the second shielding block 23 is between the first limiting surface 141 and the second limiting surface 142, when the second shielding block 23 abuts against the first limiting surface 141, the second shielding block 23 shields part of the second air inlet 1112, and correspondingly, the first shielding block 22 shields the first air inlet 1111. When the second shielding block 23 abuts against the second limiting surface 142, the second shielding block 23 is staggered with the second air inlet 1112, and correspondingly, the first shielding block 22 is staggered with the first air inlet 1111. In this way, it is ensured that the second air passage can pass airflow during the rotation of the adjusting part 2, and the airflow passing through the atomizer can be ensured to be continuous.

[0077] In another embodiment, the second air inlet 1112 can be staggered at all times during the rotation of the adjusting part 2, so that the second air inlet 1112 remains in an always-open state. At this time, it is necessary to ensure that the area of the second air inlet 1112 is greater than or equal to 1.65 mm 2 In this way, when the first air inlet 1111 is fully closed, the second air inlet 1112 can ensure the minimum air intake of the airflow resistance adjusting assembly 10.

[0078] Specifically, there are various ways to ensure that the second air inlet 1112 can be staggered at all times during the rotation of the adjusting part 2, for example, in an embodiment, the adjusting part 2 includes the annular body 21 and the first shielding block 22 connected to the annular body 21. When the annular body 21 rotates, the first shielding block 22 can shield or stagger the first air inlet 1111 to adjust the exposed area of the first air inlet 1111, and the second air inlet 1112 is not shielded, so that the second air inlet 1112 is in an always-open state. At this time, it is necessary to ensure that the area of the second air inlet 1112 is greater than or equal to 1.65 mm 2 In this way, when the first air inlet 1111 is fully closed, the second air inlet 1112 can ensure the minimum air intake of the airflow resistance adjusting assembly 10. In addition, on the basis of ensuring the minimum air intake of the second air inlet 1112, the air intake of the air passage is gradually increased through the first air inlet 1111, so as to meet the user's use demand.

[0079] In other embodiments, the adjusting part 2 includes the annular body 21 and the first shielding block 22 and the second shielding block 23 connected to the annular body 21, the second shielding block 23 is provided with the avoiding opening 231 for avoiding the second air inlet 1112, so that the second air inlet 1112 can be at least partially exposed during the rotation of the annular body 21. At this time, it is necessary to ensure that the area of the second air inlet 1112 is greater than or equal to 1.65 mm2 The first shielding block 22 can shield or offset the first air inlet 1111, so as to adjust the exposed area of the first air inlet 1111. In this way, the air inlet amount of the air passage can be gradually increased through the first air inlet 1111 on the basis of ensuring the minimum air inlet amount of the second air inlet 1112, so as to ensure the normal work of the suction resistance adjusting assembly 10.

[0080] It should be noted that the size of the avoiding opening 231 can be set according to actual needs, and the present application does not limit this.

[0081] In an embodiment, the base 1 is provided with a through hole 12 penetrating along the axial direction of the annular body 21, and the through hole 12 is used for penetrating the liquid guide element 20. In this way, the space of the base 1 itself is fully utilized to provide a mounting position for the liquid guide element 20, so that the suction resistance adjusting assembly 10 and the liquid guide element 20 are arranged compactly, and the volume of the atomizer is reduced. The annular body 21 is arranged around the circumferential side of the through hole 12 and coaxially with the through hole 12. In this way, the waste of space and conflict are avoided.

[0082] Referring to Figure 6 In an embodiment, the annular body 21 has a first side facing the base 1 along the axial direction thereof, and the first side is provided with a first protrusion 211. The first protrusion 211 is arranged circumferentially along the annular body 21, and the first protrusion 211 is used to abut against the base 1. In this way, the annular body 21 is in sliding contact with the base 1 through the first protrusion 211. The contact area between the first protrusion 211 and the base 1 is much smaller than the contact area between the annular body 21 and the base 1. When the first protrusion 211 rotates with the annular body 21, the friction between the first protrusion 211 and the base 1 is small, so that a smaller force can be applied to drive the annular body 21 to rotate. Therefore, the efficiency of the rotation of the annular body 21 is improved, the operation is simple, and the adjustment accuracy of the suction resistance adjusting assembly 10 is improved. In addition, the setting of the first protrusion 211 can also reduce the wear of the base 1 and improve the service life of the suction resistance adjusting assembly 10.

[0083] In an embodiment, the first protrusion 211 has a first abutting surface used to abut against the base 1. The first abutting surface is at least partially arranged as a first curved surface curved towards the annular body 21. In this way, the first curved surface can better disperse stress and avoid stress concentration to cause damage to the base 1. In addition, the contact area between the first curved surface and the base 1 is smaller than that between the planar surface and the base 1. Therefore, the friction between the first protrusion 211 and the base 1 is small, so that a smaller force can be applied to drive the annular body 21 to rotate. In addition, the annular body 21 rotates more smoothly, and the adjustment accuracy of the suction resistance adjusting assembly 10 is improved.

[0084] In an embodiment, the resistance adjusting assembly 10 further comprises a fixing part 3, which is mounted on the base 1, and the adjusting part 2 is limited on the base 1 through the fixing part 3, so that the shaking or displacement of the adjusting part 2 during rotation can be effectively prevented, and the accuracy of the resistance adjustment is improved. The adjusting part 2 and the base 1 are closely combined through the fixing part 3, so that the structure of the whole resistance adjusting assembly 10 is more compact, and the occupied space is smaller.

[0085] With reference to Figure 1 In an embodiment, the fixing part 3 comprises a ring-shaped pressing plate 31 and a sleeve 32. The ring-shaped pressing plate 31 is arranged along the circumferential direction of the through hole 12 and abuts against the side of the adjusting part 2 away from the base 1 along the axial direction of the through hole 12. In this way, the pressure applied by the ring-shaped pressing plate 31 on the adjusting part 2 is uniformly distributed, so that the adjusting part 2 can stably rotate. The sleeve 32 is sleeved in the through hole 12 and is in interference fit with the inner side wall of the through hole 12, so that the sleeve 32 is fixedly connected with the base 1. Since the sleeve 32 is connected with the ring-shaped pressing plate 31, the position of the ring-shaped pressing plate 31 is fixed, so that the position of the adjusting part 2 pressed by the ring-shaped pressing plate 31 is limited. In addition, although the interference fit between the sleeve 32 and the through hole 12 is tight, it does not mean that the sleeve 32 cannot be disassembled. Through appropriate tools and methods, the user can easily disassemble the sleeve 32 in order to maintain or replace the adjusting part 2 or the base 1. The design of the ring-shaped pressing plate 31 and the sleeve 32 makes the structure of the fixing part 3 and the base 1 more compact, and reduces the volume and installation space occupied by the resistance adjusting assembly 10.

[0086] It should be noted that the ring-shaped pressing plate 31 is usually made of high-strength and wear-resistant material, which can withstand greater pressure and friction force, thereby prolonging the service life of the fixing part 3.

[0087] With reference to Figure 1 and Figure 6 In an embodiment, the annular body 21 has a second side facing the ring-shaped pressing plate 31 along the axial direction thereof, and the second side is provided with a second protrusion 212 extending along the circumferential direction of the annular body 21 and abutting against the ring-shaped pressing plate 31. In this way, the annular body 21 is in sliding contact with the ring-shaped pressing plate 31 through the second protrusion 212. The contact area between the second protrusion 212 and the ring-shaped pressing plate 31 is much smaller than the contact area between the annular body 21 and the ring-shaped pressing plate 31. When the second protrusion 212 rotates with the annular body 21, the friction between the second protrusion 212 and the ring-shaped pressing plate 31 is small, so that a smaller force can drive the annular body 21 to rotate, thereby improving the efficiency of the rotation of the annular body 21 and the operation simplicity, and improving the adjustment accuracy of the resistance adjusting assembly 10. In addition, the provision of the second protrusion 212 can also reduce the wear of the ring-shaped pressing plate 31 and improve the service life of the resistance adjusting assembly 10.

[0088] In an embodiment, the second protrusion 212 has a second abutting surface to abut against the annular pressing plate 31, the second abutting surface is at least partially provided as a second curved surface curved towards the annular body 21, so that the second curved surface can better disperse stress and avoid stress concentration to cause damage to the annular pressing plate 31. In addition, the contact area between the second curved surface and the annular pressing plate 31 is smaller than that between a planar surface and the annular pressing plate 31, so that the friction between the second protrusion 212 and the annular pressing plate 31 is smaller, so that a smaller force can be applied to drive the annular body 21 to rotate, and the annular body 21 rotates more smoothly, improving the adjustment accuracy of the suction resistance adjusting assembly 10.

[0089] With reference to Figure 1 In an embodiment, the base 1 is provided with a circular arc sliding groove 13, the circular arc sliding groove 13 is provided along the circumferential direction of the annular body 21, and the annular body 21 is rotatably installed in the circular arc sliding groove 13, so that the design of the circular arc sliding groove 13 has a certain guiding effect, so that the annular body 21 can stably rotate. The design of the circular arc sliding groove 13 enables the annular body 21 to be easily installed on the base 1 without the need for complex positioning and adjustment processes.

[0090] It should be noted that the circular arc sliding groove 13 can be provided with one or more, and specifically, the number of the circular arc sliding groove 13 is not limited in the present application. In addition, when the circular arc sliding groove 13 is provided with a plurality of circular arc sliding grooves 13, the axes of the plurality of circular arc sliding grooves 13 are arranged in a same line, and the plurality of circular arc sliding grooves 13 are arranged in a spaced manner along the circumferential direction of the annular body 21, so that
