Referring to fig. 2 and 3, fig. 2 is a schematic longitudinal sectional view of a first embodiment of a nozzle of an atomizer according to the present disclosure when assembled with a sleeve and a vent duct, and fig. 3 is a partially enlarged view of a region a in fig. 2.

The atomizer 101 includes a mouthpiece 10, a housing assembly 20, an atomizing assembly 30, and a connecting assembly 40. The suction nozzle 10 has an air outlet hole 11; a mouthpiece 10 is removably mounted to the housing assembly 20 at an end remote from the power supply assembly 102, and a user draws an aerosol formed by heat-atomising a substrate to be atomised through the mouthpiece 10. The atomizing assembly 30 is accommodated in the housing assembly 20 and is used for heating and atomizing a substrate to be atomized to generate aerosol, the connecting assembly 40 is disposed at an end of the atomizing assembly 30 away from the nozzle 10 and is fixedly connected with the housing assembly 20, and the connecting assembly 40 is further used for connecting the power supply assembly 102, so that the power supply assembly 102 supplies power to the atomizer 101.

Preferably, the central axis of the venting duct 22 coincides with the central axis of the atomizer 101. The sealing element 23 is arranged between the sleeve 21 and the suction nozzle 10, the sealing element 23 is embedded into the suction nozzle 10 and the end part of the containing cavity 28 close to the suction nozzle 10, the sealing element 23 is used for sealing the end part of the sleeve 21 connected with the suction nozzle 10, so that the inner side surface of the containing cavity 28 is matched with the outer side surface of the ventilation pipeline 22 to form a liquid storage cavity 26, and the liquid storage cavity 26 is used for storing a substrate to be atomized.

The vent pipe 22 is disposed in the receiving cavity 28, and one end of the vent pipe close to the mouthpiece 10 extends to the inside of the mouthpiece 10, and the vent pipe 22 is communicated with the air outlet 11 for transmitting the aerosol to the air outlet 11 of the mouthpiece 10. In one embodiment, the part of the air duct 22 is provided with an external convex ring 29, and the external convex ring 29 is used for being clamped with the inner side surface of the air outlet hole 11 of the suction nozzle 10, so that the installation position of the air duct 22 is limited, and the air duct 22 is prevented from shaking left and right. An injection port 27 for injecting liquid into the liquid storage chamber 26 is provided at the end of the sleeve 21 connected to the suction nozzle 10. After the substrate to be atomized in the liquid storage cavity 26 is used up, the substrate to be atomized can be injected into the liquid storage cavity 26 from the liquid injection port 27, so that the atomizer 101 can be reused. The sealing element 23 is arranged at the joint of the sleeve 21 and the suction nozzle 10, seals the liquid injection port 27 for injecting liquid into the liquid storage cavity 26, and prevents the matrix to be atomized in the liquid storage cavity 26 from flowing out through the liquid injection port 27 to pollute the outer surface of the atomizer 101.

The mounting ring 24 is disposed at the connection position of the suction nozzle 10 and the sleeve 21, that is, the mounting ring 24 is disposed partially at the end of the suction nozzle 10 close to the sleeve 21 and partially at the end of the sleeve 21 close to the suction nozzle 10. The assembling ring 24 is sleeved at one end of the sleeve 21 close to the suction nozzle 10, so that the sleeve 21 and the suction nozzle 10 can be conveniently assembled, the inclination of the ventilation pipeline 22 is corrected, and a gap reserved after the sleeve 21, the suction nozzle 10 and the sealing element 23 are assembled is shielded, so that the appearance of the atomizer 101 is smooth and attractive, and the use by a user is convenient.

Specifically, one end of the mouthpiece 10 has a first step 111, and the first step 111 is located at the end of the mouthpiece 10 near one end of the sleeve 21. The first step 111 is a first annular depression of the outer surface of the nozzle 10 near one end of the sleeve 21.

The suction nozzle 10 is made of hard material, is not easy to deform, is wear-resistant and heat-resistant, and the suction nozzle 10 can be made of plastic, metal, ceramic, glass and the like. In the present embodiment, the mouthpiece 10 is shaped as a hollow tubular structure. It should be understood that in other embodiments, the cross-section of the mouthpiece 10 perpendicular to the central axis of the atomizer 101 is rectangular, and may also be circular or elliptical.

The sleeve 21 is connected with the suction nozzle 10, the material of the sleeve 21 may be the same as or different from that of the suction nozzle 10, and the material of the sleeve 21 may be metal, glass, plastic, etc. In the present embodiment, the sleeve 21 is a hollow tubular structure. In other embodiments, the cross-section of the sleeve 21 perpendicular to the central axis of the atomizer 101 is rectangular, and may also be circular or elliptical.

The seal 23 includes a seal ring 231, a first annular projection 232 and a second annular projection 233. The seal ring 231 is a main body of the seal 23 and has a cylindrical structure, and a part of the seal ring 231 is fitted between the liquid inlet 27 and the mouthpiece 10. The seal ring 231 is provided with a first annular projection 232 and a second annular projection 233. In the present embodiment, the seal ring 231, the first annular projection 232, and the second annular row of projections 233 are integrally formed.

The first annular projection 232 is disposed between the end surface of the suction nozzle 10 close to the sleeve 21 and the end surface of the sleeve 21 close to the suction nozzle 10. The first annular projection 232 can seal the liquid injection port 27 after the suction nozzle 10 is mounted on the sleeve 21, and can seal the matching position of the liquid injection port 27 and the suction nozzle 10; and the first annular protrusion 232 may serve as a stopper to limit the sealing ring 231 from being entirely sunk into the sleeve 21. The first annular protrusion 232 is made of an elastic material, such as rubber or silica gel. The maximum outer diameter of the first annular protrusion 232 is smaller than or equal to the inner diameter of the assembly ring 24, so that after the assembly ring 24 is assembled, the first annular protrusion 232 does not extrude the assembly ring 24 in the direction perpendicular to the central axis of the vent pipe 22, that is, in the radial direction, and the smoothness of the outer surface of the atomizer 101 is ensured.

The second annular protrusion 233 is made of an elastic material, such as rubber or silica gel, and when the suction nozzle 10 is mounted on the housing assembly 20, the connection between the outer ring of the second annular protrusion 233 and the suction nozzle 10 is ensured to be tightly fitted.

In one embodiment, the mounting ring 24 may be fixed to an end of the outside of the sleeve 21 near the suction nozzle 10 by interference fit and raised above an end surface of the sleeve 21 near the suction nozzle 10 to form a second step 211. For example, the end of the sleeve 21 near the suction nozzle 10 is shaped like a truncated cone, so that the mounting ring 24 can be fixed outside the sleeve 21 by interference fit. The inner side of the mounting ring 24 forms a second step 211 with the inner side end face of the sleeve 21 close to the mouthpiece 10. It should be understood that in other embodiments, the mounting ring 24 and the sleeve 21 may be integrally formed, i.e., the inner side of the end of the sleeve 21 near the mouthpiece 10 forms the second step 211, and the side wall of the second step 211 acts as the mounting ring 24.

It should be appreciated that in other embodiments, the mounting ring 24 is secured to the end of the suction nozzle 10 proximate the sleeve 21 by an interference fit and forms a second step 211 above the end surface of the suction nozzle 10 proximate the sleeve 21. The first step 111 is located outside an end of the sleeve 21 close to the mouthpiece 10.

The sum of the height of the first annular protrusion 232 in the central axis direction of the atomizer 101 (i.e., the thickness of the first annular protrusion 232) and the height of the first step 111 is slightly greater than the height of the second step 211, so that when the suction nozzle 10, the sleeve 21 and the air duct 22 are installed, the first step 111 and the second step 211 are aligned and matched, the end surface of the suction nozzle 10 close to the sleeve 21 and the end surface of the sleeve 21 close to the suction nozzle 10 clamp and extrude the first annular protrusion 232, that is, the first annular protrusion 232 is extruded in the direction parallel to the central axis of the air duct 22, so that sealing is better achieved, and the inclination of the air duct 22 or the suction nozzle 10 is corrected.

Referring to fig. 4 and 5, fig. 4 is a schematic longitudinal sectional structure view of a second embodiment of a nozzle of an atomizer provided by the present application when assembled with a sleeve and a vent duct, and fig. 5 is a partially enlarged view of a region B in fig. 4.

The end of the sleeve 21 close to the suction nozzle 10 has a third step 212, and the third step 212 is located at the end of the sleeve 21 close to the end of the suction nozzle 10; the third step 212 is a second annular depression in the outer surface of the end of the sleeve 21 near the mouthpiece 10.

The assembling ring 24 is sleeved on the third step 212, and two ends of the assembling ring 24 are respectively abutted against the bottom wall of the first step 111 and the bottom wall of the third step 212. The sum of the height of the first step 111, the height of the third step 212 and the thickness of the first annular protrusion 232 is slightly larger than the height of the mounting ring 24, so that when the mounting ring 24 is aligned with the suction nozzle 10 and the sleeve 21 when the suction nozzle 10, the sleeve 21 and the air duct 22 are mounted, the end surface of the suction nozzle 10 close to the sleeve 21 and the end surface of the sleeve 21 close to the suction nozzle 10 clamp and press the first annular protrusion 232, that is, the first annular protrusion 232 is pressed in a direction parallel to the central axis of the air duct 22, so as to seal the liquid injection port 27. By providing the mounting ring 24 at the third step 212 and the first step 111, the relative position of the suction nozzle 10 and the housing assembly 20 is prevented from shifting, thereby correcting the inclination of the air duct 22 or the suction nozzle 10. In an embodiment, the height of the first step 111 is greater than or equal to half of the height of the mounting ring 24, most of the mounting ring 24 is sleeved on the suction nozzle 10, and when the sleeve 21 and the vent pipe 22 are mounted, the mounting ring 24 is easily aligned with the bottom wall of the first step 111, so that the mounting is convenient. In another embodiment, the height of the third step 212 is greater than or equal to half of the height of the mounting ring 24, and most of the mounting ring 24 is sleeved on the sleeve 21, so that when the suction nozzle 10 and the air duct 22 are installed, the mounting ring 24 is easily aligned with the bottom wall of the third step 212, and the installation is convenient.

The outer surface of the mounting ring 24 is in smooth transition with the outer surface of the mouthpiece 10 and the outer surface of the sleeve 21. Thus, the user does not scratch his or her hands when using the nebulizer 101, and the nebulizer 101 is more beautiful in appearance. The mounting ring 24 has a shape and size that is related to the shape and size of the mouthpiece 10 and the sleeve 21. In this embodiment, the connection between the mouthpiece 10 and the sleeve 21 is cylindrical in appearance, and the mounting ring 24 is a circular ring surrounded by sheet metal.

In some embodiments, the electrode posts 42 are configured to electrically connect to the positive pole of the power module 102, and the base 41 is configured to electrically connect to the negative pole of the power module 102, thereby forming an electrical circuit. After the current is led out through the positive electrode of the power supply assembly 102, the current sequentially passes through the electrode column 42 and the second electrode claw 45, reaches the lower end of the atomization assembly 30, penetrates through the atomization assembly 30, heats the atomization assembly 30, reaches the upper end of the atomization assembly 30, and then sequentially flows back to the negative electrode of the power supply assembly 102 after passing through the first electrode claw 44, the ventilation pipeline 22 and the base 41.

Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the disclosure being indicated by the following claims.

It will be understood that the present disclosure is not limited to the precise arrangements that have been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is to be limited only by the terms of the appended claims.
