For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the protection scope required by the present application.

[0041] According to the present application, an atomization device is provided, which comprises a power supply assembly and an atomizer. The power supply assembly is used to provide power for the atomizer. The structure and working principle of the atomizer will be described in detail below in combination with the drawings.

[0042] In some embodiments, the atomizer comprises an atomization assembly 100, a suction nozzle assembly 200, a ventilation path 300 and a liquid supplement assembly 400. The atomization assembly 100 comprises a heating assembly 110 and a first liquid storage member 120. The heating assembly 110 heats and atomizes the atomization substrate stored in the first liquid storage member 120 to form an aerosol. The suction nozzle assembly 200 comprises an air outlet path 210, which is in flow communication with the heating assembly 110 and the external atmosphere respectively. The ventilation path 300 is in flow communication with the first liquid storage member 120 and the air outlet path 210 respectively. The liquid supplement assembly 400 is in fluid communication with the first liquid storage member 120 to supplement the atomization substrate for the atomization assembly 100.

[0043] According to the atomizer provided by the present application, the ventilation path 300 and the air outlet path 210 are connected. When the air outlet path 210 is sucked, the ventilation path 300 is also sucked. Through the user's suction, the ventilation purpose is achieved, and the atomization substrate is automatically supplemented during the ventilation process.

[0044] According to the atomizer provided by the present application, when the air outlet path 210 is sucked once, the internal gas of the first liquid storage member 120 is taken away at the same time to form a negative pressure cavity, which accelerates the speed of the atomization substrate entering the first liquid storage member 120 from the liquid supplement assembly 400, and reduces the risk of the paste core.

[0045] In addition, according to the atomizer provided by the present application, when not sucking, the atomization substrate is in a balanced state inside the first liquid storage member 120, and basically will not enter the atomization substrate.

[0046] In some embodiments, the liquid supplement assembly 400 has a cavity 410, the mouthpiece assembly 200 has an extending direction, and the mouthpiece assembly 200 has a first end and a second end opposite to the first end in the extending direction, the air outlet path 210 forms a first opening at the first end and a second opening at the second end.

[0047] In some embodiments, the atomization assembly 100 can include an atomization chamber 130, and the first liquid storage member 120 can be accommodated in the atomization chamber 130, and the first liquid storage member 120 can form an air exchange gap 310 with an inner side wall of the atomization chamber 130, and specifically, the first liquid storage member 120 can be arranged opposite to the inner side wall of the atomization chamber 130 in the extending direction to form the air exchange gap 310.

[0048] According to the atomizer provided in the embodiments of the present application, the atomization assembly 100 can generate aerosol, and since the atomization assembly 100 is in communication with the second opening, when a suction force such as generated by negative pressure is applied to the first opening of the first end of the mouthpiece assembly 200, the aerosol can enter the air outlet path 210 through the second opening, and then flow out of the air outlet path 210 through the first opening, so as to form a first suction process.

[0049] In some embodiments, since the air exchange path 300 is in communication with the first liquid storage member 120, for example, through the air exchange gap 310 as described above, and is also in communication with the air outlet path 210 as described above, in the suction process as described above, the suction force applied to the first opening can also reduce the pressure in the air exchange gap 310.

[0050] In some embodiments, the reduction of the pressure in the air exchange gap 310 can also reduce the pressure in the first liquid storage member 120, so as to form a pressure difference between the first liquid storage member 120 and the cavity 410 of the liquid supplement assembly 400, and in the case that the cavity 410 stores liquid, the pressure difference can promote the movement of the liquid from the cavity 410 to the first liquid storage member 120 of the atomization assembly 100. Thus, in the first suction process, both the aerosol is drawn out of the first opening, and the liquid in the cavity 410 of the liquid supplement assembly 400 is automatically supplemented into the atomization assembly 100.

[0051] In addition, in some embodiments, when the suction process is not performed, the above-mentioned ventilation gap 310 is still in communication with the air outlet path 210 via the ventilation path 300, and in the case that the first opening is in communication with the external environment, such as the atmosphere, in which the atomizer provided according to the embodiments of the present application is located, the pressure in the ventilation gap 310 is balanced with the pressure of the external environment. This pressure balance also facilitates the pressure in the first liquid storage member 120 to be balanced with the pressure in the cavity 410 of the liquid supplement assembly 400, thereby facilitating the avoidance of the situation that the liquid supplement assembly 400 is difficult to discharge liquid again due to the pressure in the cavity 410 being lower than the pressure of the external environment after the suction process.

[0052] In some embodiments, in combination with the above-mentioned Figures 1 to 3 ( Figure 2 In some embodiments, the liquid supplement assembly 400 can be, for example, a cylindrical structure, and the liquid supplement assembly 400 can also extend, for example, along the above-mentioned extension direction. The liquid supplement assembly 400 can be, for example, a columnar structure, and can have an inner side wall in a cylindrical shape (for example, a cylinder, but not limited to a cylinder) and an outer side wall in a cylindrical shape (for example, a cylinder, but not limited to a cylinder), which is located outside the inner side wall and is spaced apart from the inner side wall, thereby defining the above-mentioned cavity 410 between the inner side wall and the outer side wall.

[0053] In some embodiments, the middle part of the inner side wall in a cylindrical shape is hollow, so that the above-mentioned suction nozzle assembly 200 and the atomization assembly 100 can be arranged therein, so that the structure of the atomizer is more compact and occupies less space.

[0054] In some embodiments, one end of the liquid supplement assembly 400 in the extension direction can be open, and the opening can be closed in sequence by a liquid supplement sealing member 420 such as a sealing silica gel plug and a liquid supplement cover 430 such as a cover body, for example, by inserting the sealing silica gel plug into the opening, and then connecting the cover body to the liquid supplement assembly 400 in a detachable manner such as a snap connection to close the opening of the liquid supplement assembly 400. Specifically, a groove can be provided on the inside of the opening of the liquid supplement assembly 400, and a protruding structure for embedding the groove can be provided on the cover body.

[0055] In some embodiments, the communication mode of the liquid supplement assembly 400 and the above-mentioned part of the atomization assembly 100 can be achieved by a structure capable of draining liquid, that is, a drainage path is formed between the liquid supplement assembly 400 and the first liquid storage member 120.

[0056] In some embodiments, the structure for draining can also include an adsorbing structure that adsorbs liquid from inside the cavity 410 by its own structure, such as a porous adsorbing structure that adsorbs liquid by capillary action to put itself in a wet state. Although not shown in the figure, as an alternative, the structure for draining can include a tubular structure that can directly promote the flow of liquid out of the cavity 410 of the liquid supplement assembly 400.

[0057] In some embodiments, the above-mentioned part of the atomization assembly 100 for defining the breathing gap 310 can be, for example, an adsorbing structure that adsorbs liquid by its own structure, such as a porous adsorbing structure as mentioned in the above example, to store the liquid (i.e., the atomization substrate as mentioned above) drained from the cavity 410 of the liquid supplement assembly 400, which will be atomized into the aerosol as mentioned in the above description in the subsequent working process of the atomization assembly 100.

[0058] In some embodiments, as the adsorbing structure, the above-mentioned part of the atomization assembly 100 is in communication with the breathing gap 310 defined thereby, so that when the pressure in the breathing gap 310 decreases, the pressure in the above-mentioned part of the atomization assembly 100 also decreases accordingly. In some embodiments, the adsorbing structure can include, for example, a structure such as cotton, which will be described in detail later.

[0059] In addition, the atomization assembly 100 further includes an atomization chamber seal 150 and an atomization chamber cover 160 for sealing the atomization chamber 130.

[0060] According to the atomizer provided by the embodiments of the present application, the heating assembly 110 can be inserted into the atomization chamber 130, and a second breathing section 320 is formed between the heating assembly 110 and the atomization chamber 130, and the breathing path 300 includes the second breathing section 320, and the second breathing section 320 is in communication with the first breathing section and the breathing gap 310, respectively. In some embodiments, as mentioned later in the description, the mouthpiece assembly 200 includes a first containing member 220, and the heating assembly 110 can be inserted into the first containing member 220 while being substantially inserted into the atomization chamber 130 to form the above-mentioned second breathing section 320.

[0061] According to the atomizer provided by the embodiments of the present application, the breathing path 300 includes a first breathing section, and the first breathing section is formed inside the mouthpiece assembly 200, and the first breathing section is in communication with the breathing gap 310. The mouthpiece assembly 200 includes a first containing member 220 and a liquid absorbing member 230, the first containing member 220 has a first containing cavity, and the liquid absorbing member 230 is located in the first containing cavity, and an outer side wall of the liquid absorbing member 230 is provided with a first groove 231, and the first breathing section includes a space enclosed by the first groove 231 and the first containing member 220.

[0062] According to the atomizer provided in the embodiments of the present application, the liquid suction member 230 can include a liquid suction body, and the outer side of the liquid suction body can abut against the inner side wall of the first containing member 220. The outer side of the liquid suction body can have a first groove 231 recessed toward the inside of the liquid suction body, and the second groove 111a can extend along the extension direction to form part of the air exchange path 300.

[0063] In some embodiments, in particular, the liquid suction member 230 functions to adsorb liquid, which is mainly used to adsorb liquid that can be mixed in the aerosol from the atomization assembly 100, so as to avoid the liquid from being discharged from the first opening. The first groove 231 is opened on the outer side of the liquid suction body of the liquid suction member 230, so that the liquid suction body allows the gas to pass between the liquid suction body and the first containing member 220 even in the case of abutting against the inner side wall of the first containing member 220, to form part of the air exchange path 300. In this way, both the liquid suction body is ensured to make full use of the internal space of the first containing member 220 as much as possible, and the formation of the air exchange path 300 is ensured.

[0064] In some embodiments, the specific structure of the liquid suction member 230 can refer to the adsorption structure as described above, which will not be described herein again. In addition, in some embodiments, the liquid suction member 230 can also extend along the extension direction, for example, in a cylindrical state structure, that is, the liquid suction member 230 can also be a hollow structure facilitating the passage of aerosol, which naturally has part of the air outlet path 210 of the mouthpiece assembly 200 mentioned above.

[0065] In some embodiments, as an example, a plurality of first grooves 231 (as described above, which can be substantially grooves) can be arranged along the circumference of the outer side of the liquid suction body, such as two, three, four or even more.

[0066] According to the atomizer provided in the embodiments of the present application, the mouthpiece assembly 200 includes a mouthpiece member 240, for example, the mouthpiece member 240 can be a second containing member, a first air outlet channel is formed in the mouthpiece member 240, a second air outlet channel is formed in the liquid suction member 230, the air outlet path 210 includes the first air outlet channel and the second air outlet channel which are in communication with each other, and the mouthpiece member 240 includes a first communication part 241 which communicates the air exchange path 300 and the air outlet path 210.

[0067] In some embodiments, the first containing member 220 can be, for example, a tubular structure, and the first containing cavity can be a tube cavity defined by the tubular structure. As an example, the first containing member 220 as a tubular structure can have two ends in the extension direction, and two openings at the two ends.

[0068] In some embodiments, the first accommodating member 220 can be sleeved on the outer side of a section of the mouthpiece 240, and a step for stopping the first accommodating member 220 can be arranged on the mouthpiece 240 to provide positioning of the first accommodating member 220. In addition, as mentioned in the above description, in some embodiments, the detachable connection between the first accommodating member 220 and the atomization assembly 100 can also be that a part of the heating assembly 110 of the atomization assembly 100 is inserted into the first accommodating cavity of the first accommodating member 220, which will be described in detail later.

[0069] According to the atomizer provided in the embodiments of the present application, as shown in Figure 3 and Figure 5 The heating assembly 110 can include a sealing member 111, which can be located on the side of the heating assembly facing the mouthpiece assembly 200, can be inserted into the first accommodating member 220, and can include a sealing body. The outer side of the sealing body can abut against the inner side wall of the first accommodating member 220, and the outer side of the sealing body can have a second groove 111a recessed toward the inside of the sealing body, which can extend along the extension direction. The air exchange path 300 includes the space enclosed by the second groove 111a and the first accommodating member 220.

[0070] In this way, according to the atomizer provided in the embodiments, the outer side of the sealing body abuts against the inner side wall of the first accommodating member 220, thereby ensuring the sealing performance of the first accommodating member 220 and avoiding leakage of aerosol through the first accommodating member 220. In some embodiments, while ensuring the sealing performance of the sealing member 111, similar to the adsorbing member as described above, the sealing member 111 can be provided with the second groove 111a as described above to ensure the formation of the air exchange path 300.

[0071] According to the atomizer provided in the embodiments of the present application, the first air outlet channel is formed in the mouthpiece 240, the second air outlet channel is formed in the liquid suction member 230, the air outlet path 210 includes the first air outlet channel and the second air outlet channel that are in communication with each other, and the mouthpiece further includes a first communication part 241 that communicates the air exchange path 300 and the air outlet path 210.

[0072] According to the atomizer provided in the embodiments of the present application, the mouthpiece 240 can be detachably connected with the liquid suction member 230. In some embodiments, the end of the mouthpiece away from the first opening can be inserted into the inside of the liquid suction member 230. For example, the end of the mouthpiece can be conical and have an opening part. The conical end is partially inserted into the inside of the liquid suction member 230 so that the opening part is exposed, thereby forming a part of the first communication part 241. In some embodiments, another part of the first communication part 241 can be formed by the spacing between the mouthpiece and the liquid suction member 230 in the extension direction.

[0073] According to the atomizer provided in the embodiments of the present application, the suction nozzle assembly 200 can further include a second communication part 251, which communicates the air exchange path 300 and the air outlet path 210, and is arranged in the air flow direction Y (in the same direction as the extending direction) of the air outlet path 210 and spaced from the first communication part 241.

[0074] In some embodiments, as shown in FIG. 1, the air flow direction Y can be vertical upward, that is, the aerosol generated in the heating assembly 110 flows vertically upward to the liquid suction member 230 and the suction nozzle member 240, and the suction nozzle member 240 is located above the liquid suction member 230. Figure 2 and Figure 3 As shown in FIG. 1, in the use state of the atomizer, the air flow direction Y can be vertical upward, that is, the aerosol generated in the heating assembly 110 flows vertically upward to the liquid suction member 230 and the suction nozzle member 240, and the suction nozzle member 240 is located above the liquid suction member 230.

[0075] Thus, according to the atomizer provided in the embodiments of the present application, the first communication part 241 is arranged, and at the same time, the second communication part 251 is arranged in a spaced manner, which forms a "double insurance" for the communication of the air exchange path 300 and the air outlet path 210, and ensures that the suction process can finally cause the pressure in the air exchange gap 310 to decrease.

[0076] In addition, in some embodiments, as mentioned above, the atomization cartridge 130 is connected with the suction nozzle assembly 200 and the liquid supplement assembly 400, respectively, and the liquid supplement assembly 400 is arranged around the suction nozzle assembly 200. In some embodiments, in the use state of the atomizer, the liquid supplement assembly 400 is located above the atomization cartridge 130, so that the self-weight of the atomization substrate inside the liquid supplement assembly 400 can be used to promote the flow of the atomization substrate to the atomization cartridge 130.

[0077] According to the atomizer provided in the embodiments of the present application, the first communication part 241 is located on one side of the liquid suction member 230 in the extending direction, and the second communication part 251 is located on the other side of the liquid suction member 230 in the extending direction.

[0078] According to the atomizer provided in the embodiments of the present application, during the continuous use of the atomizer, the liquid suction member 230 can form a liquid film between the liquid suction member and the first containing member 220 due to the continuous adsorption of liquid, which can hinder or even cut off the air exchange path 300, resulting in poor communication between the air exchange path and the air outlet path 210.

[0079] Therefore, in the atomizer provided by the embodiments of the present application, on the one hand, the structure of the suction nozzle 240 is adjusted (i.e., the tapered portion and the notch portion are provided as described above) by using the assembly air exchange gap 310 between the suction nozzle 240 and the liquid suction member 230, to form the first communication portion 241 downstream of the suction airflow direction (i.e., the extension direction) in the air outlet path 210, and on the other hand, the second communication portion 251 located on the upstream side of the suction airflow direction of the liquid suction member 230 is used to ensure that even if a liquid film is generated between the liquid suction member 230 and the first containing member 220, the air outlet path 210 can be communicated with the air exchange path by bypassing the liquid film through the second communication portion 251 in front of the liquid suction member 230.
