[0027] Existing atomizer products cannot separate the aerosol matrix from the atomizer core during transportation and when not in use. This results in the atomizer core being constantly immersed in the atomizing liquid, which can affect the taste when vaping after a period of time. There is also a risk of leakage during transportation, which affects the user experience.

[0028] Based on this, in order to solve the above problems, this application designs an atomizer in which the mouthpiece can be rotated and adjusted relative to the housing assembly to change the relative position between the second liquid inlet structure on the outer tube and the first liquid inlet structure on the inner tube, thereby adjusting the liquid connection between the liquid storage chamber and the atomizing core. Furthermore, when the atomizer is in transport or not in use, by adjusting the second liquid inlet structure to block the first liquid inlet structure, the aerosol matrix in the liquid storage chamber will be isolated from the atomizing core, which can prevent the atomizing core from being immersed in the aerosol matrix for a long time, ensuring the taste of the product and improving the product's leak-proof performance.

[0029] refer to Figure 12 This application provides an electronic atomizing device, which includes an atomizer 100 and a power supply component 200. The power supply component 200 is connected to the atomizer 100 and is used to supply power to the atomizer 100.

[0030] The atomizer 100 contains a liquid aerosol matrix, and the power supply component is used to supply power to the atomizer 100, so that the atomizer 100 is powered on to heat the aerosol matrix to generate atomized gas that can be inhaled by the user.

[0031] Understandably, the electronic atomizing device of this application can be a replaceable electronic atomizing device with atomizer 100, that is, the atomizer 100 and the power supply component 200 can be detachably connected; thus, the power supply component 200 can be charged independently, or the atomizer 100 can be replenished with aerosol generation matrix independently. Alternatively, the electronic atomizing device of this application can also be a disposable electronic atomizing device, that is, the atomizer 100 and the power supply component 200 are not detachably connected; no specific limitation is made here.

[0032] refer to Figure 1 , Figure 2 and Figure 3 This application provides an atomizer, including a housing assembly 1, an atomizing core assembly 2, and a mouthpiece adjustment assembly 3. The housing assembly 1 has a liquid storage chamber 110 formed inside it. The atomizing core assembly 2 is disposed in the liquid storage chamber 110. The atomizing core assembly 2 includes an inner tube 210 and an atomizing core 220 disposed in the inner tube 210. The inner tube 210 is provided with a first liquid inlet structure 4. The mouthpiece adjustment assembly 3 includes a mouthpiece 310 and an outer tube 320 disposed on the mouthpiece 310. The mouthpiece 310 is rotatably engaged with the housing assembly 1, and the outer tube 320 is located in the liquid storage chamber 110 and sleeved outside the inner tube 210. The outer tube 320 is provided with a second liquid inlet structure 5 corresponding to the first liquid inlet structure 4. The mouthpiece 310 rotates relative to the housing assembly 1 to drive the outer tube 320 to rotate relative to the inner tube 210, so that the second liquid inlet structure 5 is connected to or blocked from the first liquid inlet structure 4.

[0033] The user can control the nozzle 310 to rotate relative to the housing assembly 1 to change the position between the second liquid inlet structure 5 on the outer tube 320 and the first liquid inlet structure 4 on the inner tube 210, thereby adjusting the liquid flow connection between the liquid storage chamber 110 and the atomizing core 220.

[0034] Specifically, when the second liquid inlet structure 5 and the first liquid inlet structure 4 are in a mutually connected position, refer to Figure 3 The aerosol matrix in the liquid storage chamber 110 can flow smoothly to the atomizing core 220 through the second liquid inlet structure 5 and the first liquid inlet structure 4 in sequence, and the liquid supply of the atomizer 100 is stable; the power supply component 200 is used to electrically connect with the atomizing core 220, and the atomizing core 220 can heat and atomize the aerosol matrix after being powered on.

[0035] When the second liquid inlet structure 5 and the first liquid inlet structure 4 are in a mutually blocking position, that is, the second liquid inlet structure 5 and the first liquid inlet structure 4 do not overlap at all; at this time, the aerosol matrix in the liquid storage chamber 110 and the atomizing core 220 are isolated by the outer tube 320, which can prevent the atomizing core 220 from being immersed in the aerosol matrix for a long time and prevent leakage.

[0036] Furthermore, during rotation, the nozzle 310 can adjust the connection between the first liquid inlet structure 4 and the second liquid inlet structure 5 to be partially or completely connected, thereby controlling the liquid inlet volume and adjusting the flavor of the atomizer 100.

[0037] Understandably, the nozzle 310 is rotatably fitted with the housing assembly 1, and the nozzle 310 will protrude from the housing assembly 1 to satisfy the user's suction needs, thereby making the rotation adjustment of the nozzle 310 convenient and quick.

[0038] Specifically, the first liquid inlet structure 4 can be a liquid inlet hole or liquid inlet groove on the inner tube 210, and the second liquid inlet structure 5 can be a liquid inlet hole or liquid inlet groove on the outer tube 320.

[0039] The atomizer 100 of this application has a mouthpiece 310 that can be rotated and adjusted relative to the housing assembly 1 to change the relative position between the second liquid inlet structure 5 on the outer tube 320 and the first liquid inlet structure 4 on the inner tube 210, thereby adjusting the liquid-conducting communication state between the liquid storage chamber 110 and the atomizing core 220. Furthermore, when the atomizer 100 is in a transport or non-use state, by adjusting the second liquid inlet structure 5 to block the first liquid inlet structure 4, the aerosol matrix in the liquid storage chamber 110 will be isolated from the atomizing core 220, which can prevent the atomizing core 220 from being immersed in the aerosol matrix for a long time, ensuring the taste of the product and improving the product's leak-proof performance.

[0040] In addition, the nozzle 310 protrudes from the housing assembly 1, making it easy for the user to hold and rotate, and the adjustment is very convenient and quick.

[0041] refer to Figure 1 , Figures 5 to 8 In some embodiments, the suction nozzle 310 includes a suction nozzle body 6 and a rotating base 7 disposed on the suction nozzle body 6; the rotating base 7 is rotatably connected to the housing assembly 1, and one end of the outer tube 320 is connected to the rotating base 7; the suction nozzle body 6 protrudes outward relative to the housing assembly 1.

[0042] Specifically, the mouthpiece body 6 protrudes outside the housing assembly 1, and the user can simply hold the mouthpiece body 6 and rotate it relative to the housing assembly 1, making the operation simple; and the adjustment is achieved by utilizing the structure of the atomizer 100 itself, which is conducive to simplifying the structure.

[0043] The outer tube 320 is connected to the rotating base 7, and the rotation of the rotating base 7 relative to the housing assembly 1 can synchronously drive the outer tube 320 to rotate relative to the inner tube 210.

[0044] refer to Figure 5 In some embodiments, the rotating base 7 is in the shape of a cylindrical tube, and an annular groove 8 is correspondingly provided on the outer wall of the housing assembly 1. The rotating base 7 is embedded and rotated within the annular groove 8.

[0045] Understandably, the rotating base 7 is set as a cylindrical tube, and one end of the outer tube 320 can be fitted inside the rotating base 7; the shape and size of the annular groove 8 are adapted to the rotating base 7, and then the arc-shaped outer tube wall of the rotating base 7 and the arc-shaped inner wall of the annular groove 8 are used to achieve rotational engagement, so that the rotating base 7 can rotate stably in the annular groove 8, making the adjustment operation smoother.

[0046] In some embodiments, the rotating base 7 is provided with a fitting 9 that fits onto and presses against the outer wall of the outer tube 320.

[0047] For example, kit 9 ​​can be, but is not limited to, an arc-shaped piece, a round tube, a U-shaped clamp, etc., to ensure that the outer tube 320 can be fitted inside kit 9.

[0048] Specifically, the outer tube 320 and the kit 9 ​​can be connected by, but not limited to, riveting, screwing, welding, or hot-melt connection; or, the outer tube 320 and the rotating base 7 can be an integrated structure, as long as they can rotate synchronously.

[0049] In one specific embodiment of this example, reference is made to... Figure 8 The kit 9 ​​includes two arc-shaped pieces symmetrically arranged on both sides of the outer tube 320. The two arc-shaped pieces are sleeved on the outer wall of the outer tube 320 and are riveted to the outer tube 320. That is, the arc-shaped pieces are pressed tightly against the outer wall of the outer tube 320 in the radial direction, thereby making the outer tube 320 and the kit 9 ​​tightly connected, effectively preventing the outer tube 320 from detaching from the nozzle 310, and keeping the structure of both stable.

[0050] refer to Figure 8 In some embodiments, the side of the kit 9 ​​facing the outer tube 320 is provided with a limiting member 10 that passes through the outer tube 320; along the axial direction of the outer tube 320, the kit 9 ​​is limited to the outer tube 320 by the limiting member 10.

[0051] Understandably, the limiting member 10 is set on the inner wall of the kit 9, and a corresponding limiting port is provided on the outer tube 320. The limiting member 10 passes through the limiting port and is installed inside the outer tube 320. The limiting member 10 can effectively limit the rotation of the outer tube 320 relative to the kit 9, and the two will maintain stable synchronous movement. In turn, it controls the rotation of the suction nozzle 310 and effectively drives the outer tube 320 to rotate synchronously.

[0052] refer to Figures 5 to 8 In some embodiments, the atomizer 100 includes a groove 11 formed on one of the inner wall of the annular groove 8 and the outer wall of the rotating base 7, and a slider 12 corresponding to the other of the inner wall of the annular groove 8 and the outer wall of the rotating base 7; the sliding stroke of the slider 12 in the groove 11 corresponds to the rotation stroke of the rotating base 7 in the annular groove 8.

[0053] Specifically, a groove 11 is formed on the inner wall of the annular groove 8, and the groove 11 is arranged along the circumferential direction of the annular groove 8; a protruding slider 12 is provided on the outer wall of the rotating base 7, the slider 12 is embedded in the groove 11 and can slide along the groove 11, so that the rotating base 7 rotates stably in the annular groove 8, thereby ensuring smooth and uninterrupted rotational adjustment and control of the suction nozzle 310; and the slider 12 and the groove 11 can also play a rotational limiting role for the rotating base 7. When the slider 12 moves to both ends of the groove 11, the side end of the groove 11 will abut against the slider 12 to limit the movement of the slider 12, thereby limiting the rotation of the rotating base 7, limiting the excessive rotation of the rotating base 7, limiting the rotational stroke, and improving rotational stability.

[0054] In addition, by using the slider 12 in conjunction with the groove 11, the rotating base 7 can be prevented from dislodging from the annular groove 8, ensuring a reliable structural connection.

[0055] refer to Figure 5 , Figure 6 and Figure 10 , Figure 11 In some embodiments, the slider 12 is movable relative to the slide groove 11 between a first position and at least one second position. The slide groove 11 is provided with positioning protrusions 13 that limit the slider 12 in the first and second positions. When the slider 12 is subjected to an external force exceeding a preset threshold, it can slide through the positioning protrusions 13. In the first position, the slider 12 is blocked from the first liquid inlet structure 4 and the second liquid inlet structure 5. In the second position, the slider 12 is connected to the first liquid inlet structure 4 and the second liquid inlet structure 5.

[0056] Specifically, the positioning protrusion 13 in the slide groove 11 provides a certain limit to the sliding of the slider 12, so that the slider 12 can be stably maintained in the first position and the second position without external force, thereby keeping the relative position between the outer tube 320 and the inner tube 210 stable. In the first position, the first liquid inlet structure 4 and the second liquid inlet structure 5 are blocked, the liquid storage chamber 110 is isolated from the atomizing core 220, and the atomizer 100 can be stably maintained in the liquid-core separation state, which is suitable for the transportation or non-use state of the atomizer 100. In the second position, the first liquid inlet structure 4 and the second liquid inlet structure 5 are connected, the liquid storage chamber 110 is connected to the atomizing core 220, and the atomizer 100 can be stably maintained in the liquid-connected state, which is suitable for the inhalation use state of the atomizer 100.

[0057] It should be noted that the thickness of the positioning protrusion 13 in the radial direction of the annular groove 8 is less than the depth of the slide groove 11; the positioning protrusion 13 only provides a certain degree of limiting effect on the slider 12, not a complete limiting effect; when the user rotates the suction nozzle 310 and applies sufficient force to the slider 12 (exceeding the preset threshold), the slider 12 can slide past the positioning protrusion 13, that is, it can change the position of the slider 12 in the slide groove 11; thus, the function of the positioning protrusion 13 is only to keep the slider 12 stably in the first and second positions without the action of external force, to avoid the slider 12 from deflection due to bumps or accidental collisions during transportation, and to improve the structural stability.

[0058] In this embodiment, the slider 12 has a first position and two second positions, and the number of positioning protrusions 13 is two. In the first position, the slider 12 is confined between the two positioning protrusions 13; in the second position, the slider 12 is confined between one of the positioning protrusions 13 located on one side of the slide groove and the corresponding side; in the other second position, the slider 12 is confined between the other side of the slide groove 11 and the corresponding side of the positioning protrusion 13. Then refer to... Figure 10 and Figure 11 With the mouthpiece 310 in the first position corresponding to the slider 12, the user can rotate the mouthpiece 310 counterclockwise or clockwise to move the slider 12 to the second position, thereby adjusting the atomizer 100's operating status. The adjustment is very flexible and convenient.

[0059] refer to Figure 10 , Figure 11 Understandably, adjustment marks such as "on" and "off" are set at different rotation positions of the nozzle 310 on the end face of the housing assembly 1 to show the liquid guiding state between the liquid storage chamber 110 and the atomizing core 220 when the nozzle 310 is in the current rotation position, so that the adjustment operation of the nozzle 310 is clearer and more definite.

[0060] refer to Figure 9In some embodiments, the atomizer 100 further includes a base assembly 15 disposed on the side of the liquid storage chamber 110 away from the mouthpiece, with the inner tube 210 inserted in the base assembly 15; and the base assembly 15 has a sealing protrusion 16 protruding into the liquid storage chamber 110, the sealing protrusion 16 abutting against the outer wall of the outer tube 320 to seal the second liquid inlet structure 5.

[0061] Specifically, when the second liquid inlet structure 5 blocks the first liquid inlet structure 4, the sealing protrusion 16 will seal the second liquid inlet structure 5, effectively preventing the liquid in the liquid storage chamber 110 from entering the outer tube 320.

[0062] Understandably, the purpose of adjusting the second liquid inlet structure 5 to block the first liquid inlet structure 4 is to isolate the aerosol matrix in the liquid storage chamber 110 from the atomizing core 220, prevent the liquid in the liquid storage chamber 110 from flowing to the atomizing core 220, improve the product's anti-leakage performance, and thus prevent the atomizing core 220 from being immersed in the aerosol matrix for a long time; then, when the outer tube 320 is rotated to the point where the second liquid inlet structure 5 blocks the first liquid inlet structure 4, the sealing protrusion 16 can just form a seal on the second liquid inlet structure 5, achieving a better isolation effect between the liquid storage chamber 110 and the atomizing core 220.

[0063] In one specific embodiment of this example, the first liquid inlet structure 4 consists of a plurality of liquid inlet holes spaced apart on the inner tube 210 along the circumferential direction, and the second liquid inlet structure 5 consists of a plurality of liquid inlet holes spaced apart on the outer tube 320 along the circumferential direction. The liquid inlet holes on the inner tube 210 correspond one-to-one with the liquid inlet holes on the outer tube 320. The number of sealing protrusions 16 corresponds to the number of liquid inlet holes on the outer tube 320. The plurality of sealing protrusions 16 are spaced apart along the circumferential direction of the outer tube 320 so as to ensure that the sealing protrusions 16 can seal each liquid inlet hole on the outer tube 320, thereby achieving a good sealing and isolation effect.

[0064] It should be noted that when the outer tube 320 is rotated to the point where the second liquid inlet structure 5 is connected to the first liquid inlet structure 4, the sealing protrusion 16 will be misaligned with the second liquid inlet structure 5, without interfering with the liquid inlet, and the liquid in the storage chamber 110 can flow smoothly into the second liquid inlet structure 5.

[0065] refer to Figures 3 to 5 In some embodiments, the atomizer 100 further includes a first sealing ring 14 disposed in the annular groove 8, and the first sealing ring 14 is sleeved on the outer tube 320.

[0066] Specifically, the annular groove 8 is connected to the liquid storage chamber 110, which allows the outer tube 320 to be fitted downwards onto the inner tube 210. A first sealing ring 14 is provided in the annular groove 8 and is fitted onto the outer tube 320. The first sealing ring 14 can fill the space between the outer tube 320 and the inner wall of the annular groove 8, effectively preventing liquid leakage in the liquid storage chamber 110 and achieving a good sealing effect.

[0067] refer to Figure 2 , Figure 4 and Figure 9 In some embodiments, the atomizing core assembly 2 further includes a second sealing ring 17 that is sealed to the inner tube 210 on the side near the mouthpiece 310; the mouthpiece 310 has an air guide tube 19 protruding toward the atomizing core 220, and a mouthpiece air passage 18 is formed in the air guide tube 19. The air guide tube 19 is inserted into the second sealing member 17 so that the mouthpiece air passage 18 communicates with the air guide of the atomizing core 220.

[0068] Specifically, the mouthpiece air passage 18 is connected to the atomizing core 220 to allow the aerosol gas generated by the heating of the atomizing core 220 to flow through the mouthpiece air passage 18 for the user to inhale. Furthermore, by providing a second sealing ring 17 at the top of the inner tube 210, and inserting the air guide tube 19 within the second sealing ring 17, the airtightness between the atomizing core 220 and the mouthpiece air passage 18 is ensured, preventing gas leakage.

[0069] The application does not specify the model of the atomizer, that is, the shape of the atomizer can be wine pot-shaped, rectangular, cylindrical, etc.

[0070] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
