Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to a suction resistance regulating component and its aerosol generation device. Background Technology

[0002] An aerosol generator is a low-pressure microelectronic atomizing device used to heat and atomize liquid aerosols into a mist-like aerosol for users to inhale. Suction resistance specifically refers to the resistance encountered when a user inhales from the aerosol generator. It is usually measured using air pressure as a metric, and suction resistance can, to some extent, represent the perceived resistance felt when the aerosol generator is inhaled. Aerosol generators typically have an opening at the bottom or side of the casing as an air inlet. The internal airflow path of the aerosol generator is fixed, and the airflow rate is not adjustable. In other words, the suction resistance of the aerosol generator is a fixed value and cannot be adjusted, thus failing to meet the varying suction resistance requirements of users during inhalation.

[0047] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0048] Please refer to the following: Figures 1 to 5 This application provides an aerosol generating device 100 for heating and atomizing a liquid aerosol generating matrix to generate aerosol for users to inhale; the aerosol generating device 100 has a suction resistance adjustment component 10, which allows users to adjust the air intake of the aerosol generating device 100 to change the suction resistance (i.e., suction resistance), thereby meeting the different usage needs of different users for suction resistance and improving the user experience.

[0049] The suction resistance adjustment assembly 10 includes a bracket 1, a fixing base 5, an air regulating component 8, and an elastic component 6. The bracket 1 and the fixing base 5 together install and fix the air regulating component 8 and the elastic component 6, ensuring that the air regulating component 8 can adjust the air intake volume. The bracket 1 has a fixing cylinder 2; an air inlet 11 is opened on the outer circumferential surface of the fixing cylinder 2, extending from the outer circumferential surface of the fixing cylinder 2 into the fixing cylinder 2, for airflow to supply air to the atomizing device of the aerosol generating device 100. The fixing cylinder 2 and the bracket 1 can be integrally formed; for example, both the fixing cylinder 2 and the bracket 1 can be integrally molded from plastic. The fixing cylinder 2 has a first port and a second port arranged opposite each other, and the interior of the fixing cylinder 2 can communicate with the outside through the first port and the second port. The fixing base 5 is connected to the bracket 1 and is correspondingly positioned to the first port to close it.

[0050] The air regulating component 8 passes through the second port into the fixed cylinder 2, thereby sealing the second port of the fixed cylinder 2. Multiple air regulating valves 31 of different sizes are distributed on the outer circumference of the air regulating component 8. These air regulating valves 31 can block part of the air inlet 11. The different sizes of the air regulating valves 31 correspond to the area of ​​the air inlet 11 that can be blocked by the air regulating valve 31. Larger-sized air regulating valves 31 block more of the air inlet 11, reducing the air intake and increasing the suction resistance, while smaller-sized air regulating valves 31 block less of the air inlet 11, increasing the air intake and decreasing the suction resistance. By blocking the air inlet 11 with air regulating valves 31 of different sizes, the actual orifice size of the air inlet 11 can be adjusted, thereby adjusting the air intake and thus changing the suction resistance.

[0051] The elastic element 6 has a resetting function when the air regulating element 8 reciprocates along its own axis; one end of the elastic element 6 abuts against the fixed seat 5, and the other end abuts against the air regulating element 8. The elastic element 6 can be a compression spring.

[0052] In use, when the user operates the air regulating component 8, in conjunction with the elastic component 6, the air regulating component 8 moves back and forth along its own axis and rotates around its own circumference. This allows for switching between different sized air regulating valves 31 and the air inlet 11, thus blocking the air inlet 11 and adjusting the air intake volume. This changes the suction resistance, meeting the different suction resistance needs of various users and improving the user experience. For example, when the user wants to increase the suction resistance, the air regulating component 8 moves and rotates, switching the larger air regulating valve 31 to the air inlet 11, blocking most of the air inlet 11 and reducing the air intake volume, thereby increasing the suction resistance. Conversely, to decrease the suction resistance, the smaller air regulating valve 31 is switched to the air inlet 11, blocking a small portion of the air inlet 11, increasing the air intake volume and reducing the suction resistance. This satisfies the user's different suction resistance needs during suction.

[0053] Please continue to refer to the following: Figures 2 to 5 Furthermore, the air regulating component 8 consists of a button 4 and an adjusting block 3. The button 4 is inserted into the second port of the fixed cylinder 2 and can slide within the fixed cylinder 2. The adjusting block 3 is equipped with an air regulating valve 31, one end of which abuts against the button 4, and the other end abuts against the elastic element 6. The bracket 1 and the fixed base 5 cooperate with each other to stably support and fix the button 4, the adjusting block 3, and the elastic element 6.

[0054] When the user presses button 4, button 4 applies a pushing force to the adjusting block 3. Under the action of the pushing force, the adjusting block 3 overcomes the elastic force of the elastic element 6 and begins to move along its own axis. At the same time, due to the structural cooperation design between button 4 and adjusting block 3, the adjusting block 3 will also rotate around its own axis in the circumferential direction during the axial movement, so that the air regulating valves 31 of different sizes can be switched to the position of the air inlet 11 in sequence.

[0055] For example, when the user presses button 4, the adjusting block 3 moves towards the fixed base 5 under the push of button 4. Simultaneously, under the combined action of friction and structural constraints, the adjusting block 3 rotates around its own axis, aligning the air regulating valves 31 of different sizes sequentially with the air inlet 11. When the larger air regulating valve 31 is aligned with the air inlet 11, it blocks a larger portion of the air inlet 11, reducing the air intake and thus increasing the suction resistance. When the smaller air regulating valve 31 is aligned with the air inlet 11, it blocks a smaller portion of the air inlet 11, increasing the air intake and thus reducing the suction resistance. When the user releases button 4, the elastic element 6 performs its reset function, pushing the adjusting block 3 and button 4 back to their initial positions, ready to respond to the next adjustment operation. In this way, the suction resistance of the aerosol generating device 100 can be flexibly adjusted to meet the diverse needs of users.

[0056] Please refer to the following: Figure 3 , Figures 5 to 7 In one embodiment, the button 4 is provided with a receiving groove 41, and the adjusting block 3 is provided with a corresponding positioning post 32. The positioning post 32 can be accurately inserted into the receiving groove 41 to ensure the stability of the adjusting block 3 during axial sliding relative to the button 4 and circumferential rotation around the positioning post 32.

[0057] For example, when the user presses button 4, the adjusting block 3 slides axially within the receiving groove 41 via the positioning post 32. Simultaneously, the adjusting block 3 rotates around its own axis with the positioning post 32 as the center, thereby switching the gas regulating valve 31. When button 4 is released, the elastic element 6 pushes the adjusting block 3 back to its original position, and the positioning post 32 slides in the opposite direction within the receiving groove 41, returning to its initial position. The entire process is smooth and stable under the stable support of the bracket 1 and the fixed base 5, ensuring the accuracy and reliability of the suction resistance adjustment operation, allowing the user to precisely adjust the suction resistance of the aerosol generating device 100 and improving the user experience. Alternatively, the positioning post 32 can be set on button 4, and the receiving groove 41 can be set on the adjusting block 3, achieving the same technical effect.

[0058] Please continue to refer to the following: Figures 3 to 6 In another embodiment, the outer peripheral surface of the button 4 is evenly spaced with multiple first teeth 42, and the outer peripheral surface of the adjusting block 3 is also evenly spaced with multiple second teeth 33. Both the first teeth 42 and the second teeth 33 are provided with inclined surfaces 211. When the user presses the button 4, the inclined surface 211 of the second tooth 33 will closely abut against the inclined surface 211 of the first tooth 42 and move along it. Due to the special design of the inclined surface 211, when the adjusting block 3 is subjected to the axial thrust of the button 4, it will generate a torque around its own axis, thereby realizing circumferential rotation. At the same time, the movement of the second tooth 33 along the inclined surface 211 of the first tooth 42 also ensures the smooth movement of the adjusting block 3 in the axial direction. For example, when the button 4 is pressed, the first tooth 42 pushes the second tooth 33, and the adjusting block 3 begins to rotate while moving axially, and the air regulating valves 31 of different sizes gradually switch to the position of the air inlet 11. The toothed and inclined 211 structure design makes the adjustment process more precise and stable, improving the reliability of the user's adjustment of the aerosol generating device 100 suction resistance process.

[0059] Please refer to the following: Figures 4 to 8Furthermore, the inner wall of the fixed cylinder 2 is provided with multiple spaced third teeth 21, and a guide groove 22 is formed between two adjacent third teeth 21. The outer peripheral surface of the button 4 is provided with a guide part 44 that matches the guide groove 22. The guide part 44 can slide within the guide groove 22 and is located between two adjacent first teeth 42. The third teeth 21 are also provided with inclined surfaces 211. The inclined surfaces 211 of the second teeth 33 abut against and move along the inclined surfaces 211 of the third teeth 21. The bracket 1 stably supports the fixed cylinder 2, and the fixed seat 5 ensures the relative position stability of the entire moving structure. The second teeth 33 match the guide groove 22 and are embedded in the guide groove 22 under the elastic force reset of the elastic element 6, thereby locking the adjusting block 3 to prevent the adjusting block 3 from rotating. In actual operation, when the user presses the button 4, the button 4 slides within the guide groove 22 through the guide part 44. This structural design ensures the stability of the axial movement of the button 4. Simultaneously, the second tooth 33 moves along the inclined surface 211 of the third tooth 21, and the torque generated causes the adjusting block 3 to rotate around its own axis, thereby switching the air regulating valve 31. For example, when the button 4 is pressed down, the guide part 44 slides downward in the guide groove 22. The second tooth 33 first moves along the inclined surface 211 of the first tooth 42. After disengaging from the inclined surface 211 of the first tooth 42, the second tooth 33 moves to the inclined surface 211 of the third tooth 21 under the elastic reset action of the elastic element 6, and moves along the inclined surface 211 of the third tooth 21, driving the adjusting block 3 to rotate continuously, switching the air regulating valve 31 of different sizes to the air inlet 11 accordingly. After the second tooth 33 disengages from the third tooth 21, it falls into the guide groove 22, restricting the adjusting block 3 from continuing to rotate, and ensuring the stability of the adjusted position. When the large-size air regulating valve 31 switches to the air inlet 11, it blocks more of the air inlet 11 area, reducing the air intake and increasing the suction resistance; when the small-size air regulating valve 31 switches to the air inlet 11, it blocks less of the air inlet 11 area, increasing the air intake and reducing the suction resistance. This structural design not only further ensures the accuracy of the movement of the button 4 and the adjusting block 3, but also increases the stability of the structure, improves the service life of the suction resistance adjustment component 10, and provides a reliable structural guarantee for the suction resistance adjustment of the aerosol generating device 100. The corners of the guide part 44 are set with arc corners, which have a guiding effect.

[0060] Please continue to refer to the following: Figure 4 , Figure 6 and Figure 8In one embodiment, the fixed cylinder 2 has a first segment 202, a second segment 201, and a third segment 203 connected in sequence. The first segment 202 and the third segment 203 are located at opposite ends of the second segment 201. The end of the button 4 near the adjusting block 3 slides in the second segment 201, while the end of the button 4 away from the adjusting block 3 extends through the third segment 203. The diameter of the third segment 203 is smaller than that of the second segment 201. This design effectively prevents the button 4 from detaching from the second segment 201. Simultaneously, the air inlet 11 extends into the first segment 202, and the adjusting block 3 slides in the first segment 202. A portion of the adjusting block 3 extends into the second segment 201, where the diameter is smaller than that of the first segment 202. This further restricts the adjusting block 3 from detaching from the first segment 202. For example, in actual operation, button 4 will not detach from the fixed cylinder 2 during the pressing and releasing process due to the limitation of the orifice diameter of the third orifice section 203, ensuring the continuity of operation. The movement of the adjusting block 3 within the first orifice section 202 is also constrained by the orifice diameter of the second orifice section 201, ensuring its stable operation. This orifice structure design not only ensures the normal movement of each part of the gas regulating component 8 within the fixed cylinder 2, but also prevents accidental detachment of components, improving the reliability of the suction resistance regulating assembly 10, and making the suction resistance regulating function of the aerosol generating device 100 operate more stably and reliably.

[0061] Please refer to the following: Figures 4 to 8 In another embodiment, the adjusting block 3 is provided with a first positioning groove 34 on the side opposite to the button 4, and the fixing base 5 is provided with a corresponding second positioning groove 54. The two ends of the elastic member 6 are respectively inserted into the first positioning groove 34 and the second positioning groove 54. The first positioning groove 34 and the second positioning groove 54 realize the limiting effect on the two ends of the elastic member 6, making the installation of the elastic member 6 more stable and effectively preventing the elastic member 6 from falling off. During the movement of the air regulating member 8, the elastic member 6 can always stay in the correct position and stably provide elastic force.

[0062] Please refer to the following: Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 9In one embodiment, the fixed cylinder 2 has a third positioning groove 23 and a screw hole 24 located beside the third positioning groove 23 at one end near the fixed base 5; the fixed base 5 has a plug 50 and a positioning part 51 and a positioning hole 52 corresponding to the third positioning groove 23 and the screw hole 24 respectively. The plug 50 is inserted into the fixed cylinder 2, and the positioning part 51 is inserted into the third positioning groove 23. The positioning hole 52 corresponds to the screw hole 24, and the screw 53 passes through the positioning hole 52 and is screwed into the screw hole 24. Its assembly structure is extremely stable. Alternatively, the fixed cylinder 2 has a third positioning groove 23 and a slot located beside the third positioning groove 23 at one end near the fixed base 5; the fixed base 5 has a plug 50 and a positioning part 51 and a buckle corresponding to the third positioning groove 23 and the slot respectively. The positioning part 51 is inserted into the third positioning groove 23, and the buckle and the slot are locked together. This also stably installs the fixed base 5 onto the fixed cylinder 2, and they will not move relative to each other. A second positioning groove 54 is provided on the plug 50.

[0063] Please continue to refer to the following: Figures 4 to 7 In one embodiment, multiple air regulating valves 31 are distributed in a stepped manner along the axial direction of the air regulating component 8. For example, the regulating block 3 has six air regulating valves 31, which are evenly distributed on the outer circumferential surface of the regulating block 3 in a circumferential direction. Correspondingly, the number of second teeth 33 is also six. This distribution allows for more hierarchical switching of air regulating valves 31 of different sizes to the air inlet 11 when the air regulating component 8 moves axially, achieving multi-level adjustment of suction resistance. At the same time, the even distribution of multiple air regulating valves 31 along the outer circumferential surface of the air regulating component 8 ensures that each air regulating valve 31 can be evenly switched to the air inlet 11 when the air regulating component 8 rotates circumferentially, making the adjustment process more stable and accurate. The bracket 1 and the fixed seat 5 ensure the stability of the air regulating component 8 and the distribution structure of the air regulating valves 31. For example, in actual suction resistance adjustment, the air regulating component 8 can achieve more delicate and precise suction resistance adjustment during axial movement and circumferential rotation due to this distribution of the air regulating valves 31. When the air regulating component 8 moves axially, the stepped air regulating valves 31 switch to the air inlet 11 in sequence to achieve different levels of air intake adjustment, corresponding to different suction resistance changes; when the air regulating component 8 rotates circumferentially, the evenly distributed air regulating valves 31 ensure the stability of the adjustment.

[0064] Please continue reading. Figure 2In another embodiment, the vent 204 is used to allow external airflow to enter the fixed cylinder 2 and flow to the atomizing device of the aerosol generating device 100 via the air inlet 11. This application provides two ways of setting the vent 204. The first way is to set the vent 204 on the outer peripheral surface of the fixed cylinder 2, the vent 204 extends from the outer peripheral surface of the fixed cylinder 2 into the fixed cylinder 2 and is connected to the air inlet 11, so that outside air can enter the fixed cylinder 2 through the vent 204. The second way is to set the vent 204 on the side of the fixed seat 5 away from the fixed cylinder 2, the vent 204 extends through the fixed seat 5 along the axial direction of the air regulating component 8 and is connected to the air inlet 11.

[0065] The specific working principle of this application is as follows:

[0066] In the initial state, the adjusting block 3 is pressed against the button 4 under the elastic force of the elastic element 6. At this time, the second tooth 33 on the adjusting block 3 abuts against the first tooth 42 of the button 4 and moves relative to it. The second tooth 33 is embedded in the guide groove 22 under the elastic force of the elastic element 6, thereby locking the adjusting block 3 to prevent the adjusting block 3 from rotating. This causes one of the air regulating valves 31 of the adjusting block 3 to abut against the air inlet 11, so that the air inlet area remains unchanged after the air inlet 11 is adjusted.

[0067] In the air adjustment state, when button 4 is pressed, the elastic element 6 is compressed by a downward force. The first tooth 42 of button 4 drives the second tooth 33 of adjusting block 3 to move downward, so that the second tooth 33 of adjusting block 3 is released from the restriction of the guide groove 22 inside the fixed cylinder 2, thereby causing adjusting block 3 to rotate 60°. When button 4 is released, the force disappears and the elastic element 6 returns to its original shape. Adjusting block 3 completes one rotation. Another air adjustment valve 31 on adjusting block 3 will then abut against and block the air inlet 11. The size of the air inlet area is changed according to the size of the air adjustment valve 31, thus adjusting the suction resistance. The operation is extremely simple and convenient.

[0068] Please continue reading. Figure 1 In actual use, the suction resistance adjustment component 10 is installed inside the housing 7 of the aerosol generating device 100, wherein the end of the button 4 is exposed outside the housing 7 for easy pressing to control the suction resistance of the aerosol generating device 100.

[0069] This application provides a suction resistance adjustment component and its aerosol generation device. The outer circumferential surface of the air regulating component is distributed with multiple air regulating valves of different sizes. When the user operates the air regulating component, in conjunction with the action of the elastic element, the air regulating component moves back and forth along its own axis, and at the same time, the air regulating component also rotates along its own circumference to switch the air regulating valves of different sizes to the air inlet, thereby blocking the air inlet and adjusting the amount of air entering the air inlet to change the suction resistance, thus meeting the different usage needs of different users for suction resistance and improving the user experience.
