The atomization assembly comprises a shell, a first atomization core and a second atomization core. The shell defines a first atomization channel and a second atomization channel. The first atomizing core is arranged in the first atomizing channel; the second atomizing core is arranged in the second atomizing channel. The suction nozzle defines an air outlet channel, and the suction nozzle is detachably arranged at the first relative position or the second relative position of the shell. In other words, the suction nozzle has two working states, when the suction nozzle is assembled at the first relative position, the air outlet channel is communicated with the first port and isolated from the second port, and in the working states, the first atomizing core works when a user smokes. When the suction nozzle is assembled at the second relative position, the air outlet channel is communicated with the second port and is isolated from the first port, and in the working state, the second atomizing core works when the user smokes. Due to the fact that the electronic atomization device is provided with the two atomization cores, when one atomization core is damaged, the other atomization core can be used, and the service life of the electronic atomization device is prolonged.

Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization, and in particular to an atomizer and an electronic atomization device. Background Art

[0002] The electronic atomization device includes an atomization core and an atomization liquid.

[0031] Compared with the prior art, the beneficial effects of the utility model are:

[0032] In the technical solution of the utility model, the atomizer includes an atomization assembly and a suction nozzle. The atomization assembly includes a shell, a first atomization core and a second atomization core, and the shell defines a first atomization channel and a second atomization channel.

In this solution, since the suction nozzle can be reused, the user's use cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0062] See also Figure 1-Figure 8 , this embodiment provides an atomizer 100, and the atomizer 100 is used for an electronic atomization device 10. The atomizer 100 may be a detachable atomizer 100. In this case, when the atomizing liquid in the atomizer 100 is used up, the atomizer 100 can be removed from the device body (the device body may include a battery 200 and electronic control components, etc.), and a new atomizer 100 can be assembled on the device body for subsequent use. The atomizer 100 can also be used for a disposable electronic atomization device 10. In this case, the atomizer 100 cannot be separated from the device body. When the atomizing liquid in the atomizer 100 is used up, the entire electronic atomization device 10 can be discarded or recycled. Specifically, the atomizer 100 includes an atomization assembly and a nozzle 140.

[0063] See also Figure 1-Figure 4 The atomizer assembly includes a housing 110, a first atomizer core 120, and a second atomizer core 130 (in other embodiments, the atomizer assembly may also include more than three atomizer cores. The following example is taken as an example that the atomizer assembly only includes the first atomizer core 120 and the second atomizer core 130). The housing 110 defines a first atomizer channel 111 and a second atomizer channel 112. The first atomizer core 120 is disposed in the first atomizer channel 111, and the second atomizer core 130 is disposed in the second atomizer channel 112. The shell 110 also defines a liquid storage chamber (the number of liquid storage chambers can be one or more, for example, the shell 110 can define two liquid storage chambers, a first liquid storage chamber 1141 and a second liquid storage chamber 1151), and atomized liquid is stored in the liquid storage chamber. The first atomization core 120 and the second atomization core 130 can both obtain the atomized liquid in the liquid storage chamber. After the first atomization core 120 obtains the atomized liquid, it can atomize the atomized liquid in the first atomization channel 111 and generate an aerosol for the user to inhale. After the second atomization core 130 obtains the atomized liquid, it can atomize the atomized liquid in the second atomization channel 112 and generate an aerosol for the user to inhale.

[0064] The suction nozzle 140 defines an air outlet channel 141, and the suction nozzle 140 can be detachably mounted at a first relative position and a second relative position of the shell 110. In other words, the suction nozzle 140 and the shell 110 have two assembly modes, and the relative position of the suction nozzle 140 and the shell 110 changes between the first assembly mode and the second assembly mode. In one embodiment, the suction nozzle 140 and the shell 110 can be assembled to two different positions of the shell 110 in the first assembly mode and the second assembly mode. In another embodiment, the suction nozzle 140 and the shell 110 can be assembled to the same position of the shell 110 in the first assembly mode and the second assembly mode, but the assembly angle of the suction nozzle 140 changes, or the position of the suction nozzle 140 itself for assembly changes.

[0065] See also Figure 4-Figure 5The first atomization channel 111 has a first port 1111 near the suction nozzle 140, and the aerosol in the first atomization channel 111 is guided out from the first port 1111 to the suction nozzle 140 for the user to inhale. The second atomization channel 112 has a second port 1121 near the suction nozzle 140, and the aerosol in the second atomization channel 112 is guided out from the second port 1121 to the suction nozzle 140 for the user to inhale. When the suction nozzle 140 is assembled in the first relative position, the air outlet channel 141 is connected to the first port 1111 and isolated from the second port 1121, so that the user can inhale the aerosol generated by the atomization of the first atomization core 120 through the suction nozzle 140, so that the second atomization core 130 does not work. When the suction nozzle 140 is assembled in the second relative position, the air outlet channel 141 is connected to the second port 1121 and isolated from the first port 1111, so that the first atomization core 120 does not work.

[0066] In this embodiment, since there are two atomizer cores, when one of the atomizer cores is damaged, the other atomizer core can be used, and the entire electronic atomizer device 10 will not be unusable, thereby improving the service life of the electronic atomizer device 10. In addition, since the suction nozzle 140 can be detachably connected to the housing 110, and the suction nozzle 140 is switched between the first relative position and the second relative position in a disassembly manner, the suction nozzle 140 can be reused. In other words, the user can purchase or customize a personalized suction nozzle 140 separately, and then purchase an atomizer component separately. The suction nozzle 140 is inhaled after being matched with the atomizer component. When the atomized liquid in the atomizer component is inhaled, the user can discard the atomizer component and keep the suction nozzle 140, and purchase a new atomizer component again so that the suction nozzle 140 can be used with the newly purchased atomizer component. In this solution, since the suction nozzle 140 can be reused, the user's use cost is reduced.

[0067] See also Figure 3-Figure 5In some embodiments, the suction nozzle 140 includes a sealing portion 142, and the sealing portion 142 is configured to seal the second port 1121 when the suction nozzle 140 is assembled in the first relative position, and to seal the first port 1111 when the suction nozzle 140 is assembled in the second relative position. This solution enables the second atomization channel 112 to be closed when the suction nozzle 140 is assembled in the first relative position, on the one hand, to prevent external foreign matter from entering the second atomization channel 112, and on the other hand, to prevent the second atomization core 130 from being opened by mistake due to abnormal changes in the air pressure in the second atomization channel 112. Similarly, this solution also enables the first atomization channel 111 to be closed when the suction nozzle 140 is assembled in the second relative position, on the one hand, to prevent external foreign matter from entering the first atomization channel 111, and on the other hand, to prevent the first atomization core 120 from being opened by mistake due to abnormal changes in the air pressure in the first atomization channel 111. In other embodiments, the sealing portion 142 may be provided separately, that is, the sealing portion 142 does not belong to the suction nozzle 140. When the user assembles the suction nozzle 140 to the first relative position, the second port 1121 is exposed, and the user may cover the sealing portion 142 on the exposed second port 1121. When the user assembles the suction nozzle 140 to the second relative position, the first port 1111 is exposed, and the user may cover the sealing portion 142 on the exposed first port 1111.

[0068] The assembly method of the nozzle 140 and the housing 110 depends on actual needs, see Figure 2 as well as Figure 5In some embodiments, the housing 110 includes a first assembly end 1121 for assembling the suction nozzle 140, and the first assembly end 1121 is arranged around the first atomization channel 111 and the second atomization channel 112. The first port 1111 and the second port 1121 can be located inside the first assembly end 1121 or outside the first assembly end 1121. In this embodiment, the first port 1111 and the second port 1121 are located outside the first assembly end 1121. The suction nozzle 140 includes a first shell 143, and when the suction nozzle 140 is assembled in the first relative position or the second relative position, the first shell 143 is sleeved on the first assembly end 1121. That is to say, in this solution, the suction nozzle 140 is assembled to the same position of the housing 110 in the first relative position and the second relative position, so that the assembly structure of the housing 110 is simple and the processing difficulty of the housing 110 is reduced. In this embodiment, a portion of the first shell 143 of the suction nozzle 140 cooperates with the first assembly end 1121, and the first shell 143 is sleeved on the first assembly end 1121 at two different angles. In another embodiment, the first shell 143 of the suction nozzle 140 may have two portions that cooperate with the first assembly end 1121, and when one portion of the first shell 143 is sleeved on the first assembly end 1121, the suction nozzle 140 and the housing 110 are in a first relative position, and when the other portion of the first shell 143 is sleeved on the first assembly end 1121, the suction nozzle 140 and the housing 110 are in a second relative position.

[0069] In the above embodiment, the first shell 143 of the suction nozzle 140 accommodates the first port 1111 and the second port 1121 regardless of whether it is in the first relative position or the second relative position. In other embodiments, the housing 110 includes a second assembly end and a third assembly end, the second assembly end is arranged around the first atomization channel 111 and is located beside the second atomization channel 112, the third assembly end is arranged around the second atomization channel 112 and is located beside the first atomization channel 111, and the suction nozzle 140 includes a second shell, and when the suction nozzle 140 is assembled in the first relative position, the second shell is sleeved on the second assembly end, and when the suction nozzle 140 is assembled in the second relative position, the second shell is sleeved on the third assembly end. In this embodiment, when the suction nozzle 140 is assembled to the first relative position, the degree of isolation from the second port 1121 is higher, which can effectively prevent the negative pressure generated at the suction nozzle 140 from being transmitted to the second port 1121, thereby preventing the second atomization core 130 from being opened by mistake. Similarly, when the suction nozzle 140 is assembled to the second relative position, the degree of isolation from the first port 1111 is higher, which can effectively prevent the negative pressure generated at the suction nozzle 140 from being transmitted to the first port 1111, thereby preventing the first atomization core 120 from being accidentally opened. In this solution, the sealing member can be separated from the suction nozzle 140. When the suction nozzle 140 covers the first port 1111, the sealing member covers the second port 1121; when the suction nozzle 140 covers the second port 1121, the sealing member covers the first port 1111.

[0070] In the above embodiments, the suction nozzle 140 is sleeved outside the housing 110. In other embodiments, the suction nozzle 140 can also be inserted into the housing 110. Specifically, the housing 110 includes a third shell for assembling the suction nozzle 140, and the third shell is arranged around the first atomization channel 111 and the second atomization channel 112. The suction nozzle 140 includes a fourth assembly end. When the suction nozzle 140 is assembled in the first relative position or the second relative position, the fourth assembly end is inserted into the third shell and covers the first port 1111 and the second port 1121. That is, in this embodiment, the suction nozzle 140 is inserted into the housing 110, and after the suction nozzle 140 is inserted into the housing 110, the suction nozzle 140 covers the first port 1111 and the second port 1121 at the same time.

[0071] In the above-mentioned embodiments, the suction nozzle 140 covers both the first port 1111 and the second port 1121 when assembled in the first relative position and the second relative position. In other embodiments, the suction nozzle 140 may also cover only one port when assembled in the first relative position and the second relative position. Specifically, the housing 110 includes a fourth shell and a fifth shell, the fourth shell is arranged around the first atomizing channel 111 and is located beside the second atomizing channel 112, the fifth shell is arranged around the second atomizing channel 112 and is located beside the first atomizing channel 111, the suction nozzle 140 includes a fifth assembly end, the suction nozzle 140 is inserted into the fourth shell and connected to the first port 1111 when assembled in the first relative position, and the suction nozzle 140 is inserted into the fifth shell and connected to the second port 1121 when assembled in the second relative position. In this embodiment, when the suction nozzle 140 is assembled to the first relative position, the degree of isolation from the second port 1121 is higher, which can effectively prevent the negative pressure generated at the suction nozzle 140 from being transmitted to the second port 1121, thereby preventing the second atomization core 130 from being opened by mistake. Similarly, when the suction nozzle 140 is assembled to the second relative position, the degree of isolation from the first port 1111 is higher, which can effectively prevent the negative pressure generated at the suction nozzle 140 from being transmitted to the first port 1111, thereby preventing the first atomization core 120 from being opened by mistake. In this solution, the sealing member can be separated from the suction nozzle 140, and when the suction nozzle 140 covers the first port 1111, the sealing member covers the second port 1121; when the suction nozzle 140 covers the second port 1121, the sealing member covers the first port 1111.

[0072] See also Figure 4-Figure 6In some embodiments, the housing 110 has a first liquid storage chamber 1141 and a second liquid storage chamber 1151 which are isolated from each other. Atomized liquid is provided in the first liquid storage chamber 1141 and the second liquid storage chamber 1151. The first atomizer core 120 is used to obtain the atomized liquid stored in the first liquid storage chamber 1141, and the second atomizer core 130 is used to obtain the atomized liquid stored in the second liquid storage chamber 1151. In this embodiment, when the user is sucking the atomized liquid in the first liquid storage chamber 1141 and the first atomizer core 120 is damaged, the user can also use the second atomizer core 130 to suck the atomized liquid in the second atomizer chamber, so that the entire atomizer 100 will not be scrapped due to the damage of one of the atomizer cores, thereby extending the service life of the atomizer 100. Furthermore, since the first liquid storage chamber 1141 is isolated from the second liquid storage chamber 1151, the atomized liquid in the first liquid storage chamber 1141 and the atomized liquid in the second liquid storage chamber 1151 can have different flavors, thereby making the atomizer 100 have more flavors. In particular, since a single atomizer core has a certain service life, the amount of liquid stored in a single atomizer 100 needs to match the service life of the atomizer core. In order to avoid waste, the capacity of the atomized liquid in a single atomizer 100 cannot be excessive. In this embodiment, since there are two atomizer cores, the maximum liquid storage capacity of the atomizer 100 is increased without wasting the atomized liquid.

[0073] In some other embodiments, the housing 110 has a third liquid storage chamber, in which atomized liquid is stored, and the first atomizing core 120 and the second atomizing core 130 are used to obtain the atomized liquid in the third liquid storage chamber. In this embodiment, since there are two atomizing cores, the service life of the atomizer 100 can be improved on the one hand, and the maximum liquid storage capacity of the atomizer 100 can also be increased on the other hand.

[0074] See also Figure 4-Figure 6 In some embodiments, the housing 110 further has a first air inlet channel 113, and the first atomizing channel 111 and the second atomizing channel 112 are both connected to the air inlet channel. In this solution, the space occupied by the air inlet channel can be reduced, and the volume of the atomizer 100 can be reduced.

On the one hand, the internal space of the atomizer 100 can be more reasonably utilized; on the other hand, it can also facilitate the circuit routing of the circuit board 170 and facilitate the control of the first atomization core 120 and the second atomization core 130.
