The terms "connected" and "coupled" are used in this document to mean either a direct or an indirect connection (coupling) between objects, unless otherwise specified.

[0039] In one embodiment of the present application, an atomizer is disclosed, as shown in FIGS. 1-5. The atomizer includes a housing 100, a liquid storage member 200, a liquid supplement container 300, a liquid injection plug 400, and other components as needed.

[0040] The housing 100 can be understood as a collection of components that constitute the basic structural framework and the outer contour of the aerosol generating device. With the housing 100, the aerosol generating device can be held, moved, operated, and used.

[0041] In an embodiment, referring to FIGS. 3 and 4, the shell 100 is provided with a storage cavity 110, and a storage member 200 is arranged in the storage cavity 110. The storage member 200 can be storage cotton, a storage block, storage fiber or other elements capable of storing liquid atomization substrate. A liquid supplement container 300 is detachably arranged in the shell 100. The liquid supplement container 300 has a container mouth 310. A liquid supplement through hole 111 is arranged on the cavity wall of the storage cavity 110. The container mouth 310 of the liquid supplement container 300 is in communication with the liquid supplement through hole 111 to supply liquid to the storage member 200. A liquid injection channel 112 is arranged on the cavity wall of the storage cavity 110. A liquid injection plug 400 is used to block the liquid injection channel 112.

[0042] In the embodiments of the present application, the liquid injection plug 400 and the liquid supplement container 300 are arranged in the atomizer at the same time, providing two supply paths for the liquid atomization substrate, improving the total atomization substrate capacity of the atomizer, and increasing the endurance number of the atomization device. The liquid injection plug 400 is suitable for pre-injection of the atomization substrate at the factory, and the liquid supplement container 300 can achieve rapid and large replenishment.

[0043] In an embodiment, referring to FIGS. 3-5, the shell 100 is provided with an open mounting groove 120. The liquid injection channel 112 is arranged at the groove bottom of the mounting groove 120. The liquid supplement container 300 is detachably arranged in the mounting groove 120. The groove bottom of the mounting groove 120 refers to the groove wall opposite to the opening of the mounting groove 120. The arrangement of the mounting groove 120 not only provides a mounting space for the liquid supplement container 300 so as to mount and fix the liquid supplement container 300, but also provides a mounting position for the liquid injection plug 400 hidden in the mounting groove 120, which helps to protect the liquid injection plug 400, so as to reduce the possibility of damage or blockage of the liquid injection plug 400 in daily use. The liquid injection channel 112 arranged at the groove bottom of the mounting groove 120 helps to overcome the problem of increased injection difficulty caused by the arrangement of the liquid injection channel 112 in the mounting groove 120, and facilitates the adjustment of the liquid injection plug 400 through the opening of the mounting groove 120. In other embodiments, a liquid supplement position for mounting the liquid supplement container 300 can be arranged outside the shell 100. The liquid supplement container 300 is mounted on or removed from the liquid supplement position to realize the mounting and replacement of the liquid supplement container 300.

[0044] Since the mounting groove 120 of the liquid supplement container 300 is in communication with the liquid supplement through hole 111, the liquid supplement container 300 can be used to shield the liquid supplement through hole 111. After the liquid supplement container 300 is removed, the storage cavity 110 can be supplemented with atomization substrate through the liquid supplement through hole 111 according to needs, further increasing the endurance number of the device. When used by the user, a small amount of liquid atomization substrate can be directly added by removing the liquid injection plug 400, or a large amount of liquid atomization substrate can be quickly supplemented by replacing the liquid supplement container 300. The liquid supplement method is flexible, which helps to improve the use convenience of the atomizer and also improves the maximum storage capacity of the atomizer.

[0045] In one embodiment, referring to FIG. 3 and FIG. 5, the liquid supplement passage hole 111 is arranged on the cavity wall between the mounting groove 120 and the liquid storage cavity 110, so that the mounting groove 120 and the liquid storage cavity 110 are directly communicated through the liquid supplement passage hole 111. In other embodiments, the liquid supplement passage hole 111 can also be arranged on other cavity walls of the liquid storage cavity 110 according to design and use requirements, and communicated with the mounting groove 120 by arranging a passage.

[0046] Exemplarily, referring to FIG. 3-FIG. 5, the shell 100 is a long strip structure with a length direction, the mounting groove 120 is arranged at one end of the shell 100 along the length direction, the opening of the mounting groove 120 is arranged on the end wall of the shell 100, the liquid storage cavity 110 is arranged on the side of the mounting groove 120 away from the opening of the mounting groove 120 and is arranged separately from the mounting groove 120, the liquid injection passage 112 is arranged with two, and the liquid supplement passage hole 111 and the two liquid injection passages 112 are arranged side by side on the cavity wall between the mounting groove 120 and the liquid storage cavity 110 to communicate the mounting groove 120 and the liquid storage cavity 110. The positions of the liquid supplement passage hole 111 and the liquid injection passage 112 can be arranged as required, for example, the liquid supplement passage hole 111 can be arranged in the middle region of the cavity wall between the mounting groove 120 and the liquid storage cavity 110, and the two liquid injection passages 112 can be arranged at the corner positions of the cavity wall between the mounting groove 120 and the liquid storage cavity 110.

[0047] In one embodiment, referring to FIG. 3, the atomizer comprises a liquid guide pipe 500, one end of which is embedded in the liquid storage piece 200, the other end of the liquid guide pipe 500 is connected with the container port 310 of the liquid supplement container 300, the inner cavity of the liquid guide pipe 500 is communicated with the container port 310 of the liquid supplement container 300, and the portion of the liquid guide pipe 500 embedded in the liquid storage piece 200 has a liquid outlet hole 510. The liquid guide pipe 500 can guide the flow of the atomized substrate discharged from the container port 310 of the liquid supplement container 300, so that the atomized substrate can only be discharged from the liquid outlet hole 510 into the liquid storage cavity 110 and then be absorbed by the liquid storage piece 200. The covering of the liquid outlet hole 510 by the liquid storage piece 200 helps to limit the discharge speed of the liquid supplement container 300.

[0048] Exemplarily, referring to FIG. 3, the liquid guide pipe 500 is a tube body with both ends open, the annular insertion slot 113 is arranged on the cavity wall of the liquid storage cavity 110 away from the mounting groove 120 side, the annular insertion slot 113 is opposite to the liquid supplement through hole 111, one end of the liquid guide pipe 500 is inserted and fixed in the annular insertion slot 113, and the other end is inserted into the liquid supplement through hole 111 and abuts against the container port 310 of the liquid supplement container 300, so that the inner cavity of the liquid supplement container 300 and the inner cavity of the liquid guide pipe 500 are communicated. The liquid outlet hole 510 is arranged on the side of the liquid guide pipe 500 close to the annular insertion slot 113, and the liquid storage piece 200 is covered therein. In some embodiments, the first sealing sleeve 1111 can be arranged in the liquid supplement through hole 111, and the container port 310 of the liquid supplement container 300 and the liquid guide pipe 500 are both inserted into the first sealing sleeve 1111, so that the container port 310 of the liquid supplement container 300 and the inner cavity of the liquid guide pipe 500 can be sealed and communicated to prevent leakage.

[0049] Since the liquid outlet hole 510 is covered in the liquid storage piece 200, with the liquid outlet from the liquid outlet hole 510, the liquid storage piece 200 around the liquid storage hole is wetted by the absorption of the atomized substrate, and in some cases, a liquid seal-like sealing effect can be formed on the liquid outlet hole 510, so that the air in the liquid storage cavity 110 is difficult to enter the liquid supplement container 300 through the liquid outlet hole 510, resulting in a pressure difference between the liquid storage cavity 110 and the liquid supplement container 300, so that the atomized substrate in the liquid supplement container 300 is difficult to be normally discharged, and the liquid outlet of the liquid outlet hole 510 is affected.

[0050] In this regard, in one embodiment, referring to FIG. 3, the liquid guide pipe 500 has a pressure relief hole 520, which avoids the liquid storage piece 200 to communicate with the liquid storage cavity 110. The air in the liquid storage cavity 110 can enter the liquid supplement container 300 through the pressure relief hole 520, so as to balance the pressure in the liquid storage cavity 110 and the liquid supplement container 300, avoid the formation of pressure difference between the liquid storage cavity 110 and the liquid supplement container 300, and help the atomized substrate in the liquid supplement container 300 to be emptied. Exemplarily, the pressure relief hole 520 is arranged on the side of the liquid storage piece 200 close to the mounting groove 120, that is, in the view angle shown in FIG. 3, the pressure relief hole 520 is located above the liquid storage piece 200 and is higher than the liquid outlet hole 510, which helps to ensure that the liquid outlet hole 510 serves as the main liquid outlet channel, thereby helping the pressure relief hole 520 to play the pressure relief effect.

[0051] As to the specific manner in which the pressure relief hole 520 avoids the liquid storage member 200 from being in communication with the liquid storage cavity 110, in some embodiments, the height of the liquid storage member 200 can be set to be less than the height of the liquid storage cavity 110, so that a gap is formed between the liquid storage member 200 and the cavity wall of the installation groove 120, and the pressure relief hole 520 is arranged on the portion of the liquid guide pipe 500 located in the gap. In addition, a recess can be arranged on the cavity wall of the installation groove 120, and the pressure relief hole 520 is arranged on the portion of the liquid guide pipe 500 located in the recess. Of course, other arrangements that can avoid the liquid storage member 200 from being in communication with the liquid storage cavity 110 can also be adopted.

[0052] In one embodiment, referring to FIGS. 3 and 4, the container port 310 of the liquid supplement container 300 is provided with a valve core 320, and a top rod 530 is arranged in the liquid guide pipe 500. When the container port 310 of the liquid supplement container 300 is inserted into the liquid supplement through hole 111, the top rod 530 pushes the valve core 320 into the inner cavity of the liquid supplement container 300, so that the container port 310 of the liquid supplement container 300 is in communication with the inner cavity of the liquid guide pipe 500. The arrangement of the valve core 320 enables the container port 310 of the liquid supplement container 300 to be in a closed state before the top rod 530 is inserted, which helps to avoid leakage during the process of inserting the liquid supplement container 300 into the installation groove 120.

[0053] For example, referring to FIGS. 3 and 4, the inner cavity of the liquid supplement container 300 is provided with a valve body 330, the valve core 320 is arranged on the valve body 330 in a sliding manner along the axial direction of the container port 310, one end of the valve core 320 close to the container port 310 is provided with a plug 321, the plug 321 can be inserted into the container port 310 to block the container port 310, and a sealing ring 322 is arranged on the plug 321. The top rod 530 is inserted and fixed in the liquid guide pipe 500, one end of the top rod 530 extends into the installation groove 120 through the liquid supplement through hole 111, so that the valve core 320 is pushed into the inner cavity of the liquid supplement container 300 when the container port 310 of the liquid supplement container 300 is inserted into the liquid supplement through hole 111.

[0054] In some embodiments, referring to FIGS. 3 and 4, a resilient member 340 is further arranged between the valve core 320 and the valve body 330, and the resilient member 340 is used to apply an elastic force to the valve core 320 in the direction close to the container port 310, which helps to avoid accidental opening of the valve core 320, and enables the valve core 320 to automatically block the container port 310 when the liquid supplement container 300 is disassembled. The resilient member 340 can be a spring, an elastic rubber pad, a leaf spring or other elastic structural members that can generate an elastic force meeting the design requirements.

[0055] In one embodiment, referring to FIG. 3, the liquid storage cavity 110 is provided with an atomizing tube 600 arranged side by side with the liquid guide tube 500, the atomizing tube 600 is at least partially embedded in the liquid storage member 200, the inner cavity of the portion of the atomizing tube 600 in the liquid storage member 200 is provided with an atomizing core 610, and the tube wall of the atomizing tube 600 is provided with a liquid inlet hole 620 corresponding to the atomizing core 610. The atomizing substrate absorbed in the liquid storage member 200 can be sucked into the atomizing core 610 through the liquid inlet hole 620 and atomized under the heating of the atomizing core 610. As the atomizing substrate in the liquid storage member 200 near the atomizing core 610 is absorbed, atomized and discharged, the atomizing substrate in other areas of the liquid storage member 200 will migrate to the vicinity of the atomizing core 610 to continuously supply the atomizing substrate to the atomizing core 610.

[0056] For example, referring to FIGS. 3 and 4, the liquid guide tube 500 and the atomizing tube 600 are arranged on both sides of the liquid storage cavity 110, the atomizing core 610 is inserted and fixed in the middle of the inner cavity of the atomizing tube 600, the tube wall of the atomizing tube 600 on the side of the atomizing core 610 is provided with a liquid inlet hole 620, and the liquid inlet hole 620 is covered in the liquid storage member 200. The atomizing core 610 refers to a core that can heat and atomize the atomizing substrate, for example, the atomizing core 610 includes a heating net 611 and a first liquid absorbing member 612 covered outside the heating net 611, the first liquid absorbing member 612 is used to absorb the atomizing substrate provided by the liquid storage member 200 for the heating net 611 to heat and atomize. For example, the first liquid absorbing member 612 can be an oil absorbing cotton, a ceramic core or the like porous structure.

[0057] In one embodiment, referring to FIG. 3, the end wall of the shell 100 provided with the opening of the mounting groove 120 is provided with an air outlet 130, the atomizing tube 600 is connected with an air outlet tube 700 at one end close to the air outlet 130, the air outlet tube 700 has an inner cavity as at least part of the air outlet channel for supplying the atomized atomizing substrate to the air outlet 130. In some embodiments, a second sealing sleeve 710 can be sleeved at the connection between the atomizing tube 600 and the air outlet tube 700 to seal the connection between the atomizing tube 600 and the air outlet tube 700 and reduce the loss of the atomized atomizing substrate during the transmission. The air outlet tube 700 and the mounting groove 120 are arranged side by side in the shell 100 of the atomizer in the transverse direction, and the liquid storage cavity 110 is located at the same end of the air outlet tube 700 and the mounting groove 120 in the longitudinal direction (the length direction of the air outlet tube 700), so that the mounting groove 120 where the liquid supplement container 300 is located can be as large as possible and a larger volume liquid supplement container 300 can be installed. In addition, in one embodiment, a second liquid absorbing member 720 can be further arranged around the air outlet tube 700, the second liquid absorbing member 720 can be an oil absorbing cotton, and the air outlet tube 700 has a certain distance between the end and the air outlet 130, and the second liquid absorbing member 720 is at least partially located between the air outlet 130 and the end of the air outlet tube 700 to absorb the condensed liquid during the atomization.

[0058] In one embodiment, referring to FIG. 3 and FIG. 4, the liquid storage member 200 is provided with a gap 114 between the liquid storage cavity 110 and the cavity wall of the installation slot 120. The liquid storage cavity 110 is provided with a positioning protrusion 711 for limiting the position of the liquid storage member 200 in the axial direction of the liquid guide tube 500, so that the pressure relief hole 520 remains exposed in the gap 114. The positioning protrusion 711 helps to avoid the liquid storage member 200 from being offset and covering the pressure relief hole 520, so as to ensure that the pressure relief hole 520 can normally function.

[0059] For example, referring to FIG. 3 and FIG. 4, the positioning protrusion 711 is integrally arranged on the second sealing sleeve 710 at the connection between the atomizing tube 600 and the air outlet tube 700, so that the second sealing sleeve 710 can seal the connection between the atomizing tube 600 and the air outlet tube 700 while limiting the position of the liquid storage member 200. In other embodiments, the positioning protrusion 711 can also be arranged on the cavity wall of the liquid storage cavity 110 or other components in the liquid storage cavity 110, as long as it can limit the displacement of the liquid storage member 200 in the axial direction of the liquid guide tube 500.

[0060] In one embodiment, referring to FIG. 3 and FIG. 4, the shell 100 further comprises a liquid suction cavity 140 which is isolated from the liquid storage cavity 110. The cavity wall of the liquid suction cavity 140 is provided with an air inlet hole. The inner cavity of the atomizing tube 600 is in communication with the liquid suction cavity 140, and the liquid suction cavity 140 is provided with a liquid suction cotton 142. For example, the cavity wall of the liquid suction cavity 140 away from the liquid storage cavity 110 is provided with an air inlet column 141. The air inlet column 141 is provided with a through hole in the axial direction, which serves as the air inlet hole. The air inlet hole is used to provide an air inlet passage for the atomizing tube 600, so that gas enters the atomizing tube 600. During use, the condensate generated by the aerosol in the atomizing tube 600 and the unintended liquid leakage from the liquid storage cavity 110 can accumulate in the liquid suction cavity 140, and the liquid suction cotton 142 can absorb such liquid, reducing the possibility of liquid flooding the air inlet hole or leaking out of the shell 100 from the air inlet hole.

[0061] In one embodiment of the atomizing device, referring to FIG. 1-6, the atomizing device comprises the atomizer of any one of the above embodiments.

[0062] In one embodiment, the atomizing device further comprises a housing 800, which comprises a main body part 810 and a suction nozzle part 820 arranged at one end of the main body part 810. The main body part 810 is internally formed with a receiving cavity 811. The main body part 810 further comprises an installation hole 812 arranged at one side of the suction nozzle part 820 and in communication with the receiving cavity 811.
