Referring to fig. 1 and 2, a nebulizer 10 according to an embodiment of the present application will now be described.

The atomizer 10 includes a liquid reservoir 100, an atomizing assembly 200, a base assembly 300, and a seal 400. Referring to fig. 3 and 4 in combination, the liquid storage cup 100 has a receiving cavity 101, a bottom of the receiving cavity 101 is opened to form a mounting opening 102, the atomizing assembly 200 is mounted in the receiving cavity 101 of the liquid storage cup 100 through the mounting opening 102, and the base assembly 300 is inserted into the mounting opening 102 of the liquid storage cup 100. The base assembly 300, the atomizing assembly 200 and the liquid storage cup 100 together define an air flow channel 12 with two open ends, the atomizing assembly 200 and the liquid storage cup 100 together define a liquid storage cavity 11 for storing atomized liquid, the atomizing assembly 200 further has a first liquid permeation channel 13 communicating the liquid storage cavity 11 and the air flow channel 12, and the atomizing assembly 200 can atomize the atomized liquid flowing into the air flow channel 12 from the liquid storage cavity 11 through the first liquid permeation channel 13 into aerosol, and the air flow channel 12 is used for allowing external air to enter and carrying the aerosol to flow out of the atomizer 10. The injection molding member 400 is molded on the surface of the base assembly 300 and the surface of the liquid storage cup 100, so that the base assembly 300 and the liquid storage cup 100 are welded together.

It should be noted that, the injection molding of the injection molding member 400 onto the surface of the base assembly 300 and the surface of the liquid storage cup 100 is performed in an in-mold manner, and it is understood that a part of the injection molding member 400 is performed on the surface of the base assembly 300, and another part of the injection molding member 400 is performed on the surface of the liquid storage cup 100, specifically, a part of the injection molding member 400 is performed on the outer side surface and/or the bottom end surface of the base assembly 300, and another part of the injection molding member 400 is performed on at least one of the outer side surface, the inner side surface, and the bottom end surface of the liquid storage cup 100, so long as the injection molding member 400 can fixedly connect and weld the base assembly 300 and the liquid storage cup 100 together, and the injection molding member 400 can seal the gap between the base assembly 300 and the liquid storage cup 100.

In this embodiment, the bottom surface of the base assembly 300 may be flush with the bottom surface of the liquid storage cup 100, or the bottom surface of the base assembly 300 may extend out of the accommodating cavity 101 or be located in the accommodating cavity 101 and not flush with the bottom surface of the liquid storage cup 100. May be set as needed, and this embodiment is not limited thereto.

When the atomizer 10 provided in this embodiment works, referring to fig. 4, the atomization assembly 200 atomizes the atomized liquid flowing into the airflow channel 12 from the liquid storage cavity 11 through the first seepage channel 13 to form aerosol, and the aerosol flows out of the atomizer 10 from the other end of the airflow channel 12 along with the air flowing into the airflow channel 12 from one end of the airflow channel 12, so as to be absorbed by a user; in addition, referring to fig. 3, in the atomizer 10 provided in this embodiment, since the base assembly 300 and the liquid storage cup 100 are connected as a whole after being welded by the injection seal 400 formed by injection molding in a mold, the base assembly 300 and the liquid storage cup 100 are tightly sealed and stably connected, so that the problem that the base assembly 300 and the liquid storage cup 100 are not tightly sealed or the base assembly is loosened from the liquid storage cup 100 is avoided, and further, the yield of the atomizer 10 is improved, and even, the problem that a user can not destructively detach the base assembly 300 to add some other liquids harmful to human bodies to the liquid storage cavity 11, thereby affecting the safety of the atomizer 10 used by the user is avoided.

In addition, the base assembly 300 and the liquid storage cup 100 are connected into a whole through the injection sealing piece 400, so that a sealing effect can be achieved without arranging a sealing structure between the base assembly 300 and the liquid storage cup 100, the assembly process of the base assembly 300 and the liquid storage cup 100 can be simplified, the production efficiency is improved, and the production cost is reduced.

In addition, because the base assembly 300 and the liquid storage cup 100 are connected into a whole after being welded through the sealing piece 400, a user can hardly detach the base assembly 300 from the liquid storage cup 100, so that the problem of liquid leakage of the atomizer 10 caused by self-disassembling and assembling of the atomizer 10 by the user can be avoided, and the potential safety hazard caused by self-filling of the atomized liquid by the user can be avoided.

Referring to fig. 5, in another embodiment of the present application, a first annular groove 301 is formed at a connection portion between the base assembly 300 and the liquid storage cup 100, the first annular groove 301 is located between an inner side surface of the liquid storage cup 100 and an outer side surface of the base assembly 300, and the sealing member 400 includes an insert portion 410, and the insert portion 410 is injection molded in the first annular groove 301.

It will be appreciated that the first annular groove 301 is defined by the base assembly 300 and the liquid storage cup 100, and that a portion of the groove wall of the first annular groove 301 belongs to the outer side of the base assembly 300, and another portion of the groove wall of the first annular groove 301 belongs to the inner side of the liquid storage cup 100.

The atomizer 10 provided in this embodiment, because the embedding portion 410 is embedded between the base assembly 300 and the liquid storage cup 100, the embedding portion 410 has good concealment, is not easily affected by external factors and is separated from the first annular groove 301, which is favorable for keeping the base assembly 300 and the liquid storage cup 100 stably and fixedly connected for a long time, and because the embedding portion 410 is welded and embedded between the base assembly 300 and the liquid storage cup 100, the embedding portion 410 is equivalent to the deep part of the gap between the base assembly 300 and the liquid storage cup 100, which is used for welding and plugging the gap between the base assembly 300 and the liquid storage cup 100, and has large sealing area, which is favorable for stably sealing the gap between the base assembly 300 and the liquid storage cup 100 for a long time.

Referring to fig. 5, in another embodiment of the present application, as a specific implementation manner of the first annular groove 301, an outer side surface of the base assembly 300 includes a first step surface 303 and a first outer peripheral surface 304, the first step surface 303 is recessed toward a top end surface of the base assembly 300 with respect to a bottom end surface of the base assembly 300, the first step surface 303 surrounds an outer side of the bottom end surface of the base assembly 300, and the first outer peripheral surface 304 is connected between the first step surface 303 and the bottom end surface of the base assembly 300; the first step surface 303 is located inside the mounting opening 102, and the first step surface 303, the first outer peripheral surface 304 and the inner side surface of the liquid storage cup 100 define a first annular groove 301.

In the atomizer 10 provided in this embodiment, since the first step surface 303 is approximately perpendicular to the depth direction of the mounting opening 102, the surface of the embedded portion 410 connected to the first step surface 303 is also approximately perpendicular to the depth direction of the mounting opening 102, so that when the base assembly 300 is pulled out of the mounting opening 102, the pulling force acts on the embedded portion 410 vertically, the embedded portion 410 can stop the base assembly 300 from moving downward, and further the base assembly 300 is blocked from falling out of the mounting opening 102, and the base assembly 300 is prevented from being easily released from the liquid storage cup 100.

Optionally, the inner side surface of the liquid storage cup 100 includes an inclined surface 103, the inclined surface 103 is connected to the bottom end surface of the liquid storage cup 100, the inclined surface 103, the first step surface 303 and the first outer peripheral surface 304 together define a first annular groove 301, the inclined surface 103 gradually inclines outwards in a direction from the top to the bottom of the liquid storage cup 100, and the inclined surface 103 is beneficial to increasing the welding area of the liquid storage cup 100 and the embedded portion 410, so that the liquid storage cup 100 and the embedded portion 410 are connected more firmly.

Referring to fig. 5, in another embodiment of the present application, the bottom end surface of the base assembly 300 protrudes to the outside of the mounting opening 102; the injection molding member 400 further includes an injection molding body 420 integrally formed with the insert portion 410, and the injection molding body 420 is injection molded in a mold on the first outer peripheral surface 304 and the bottom end surface of the liquid storage cup 100.

The atomization core 220 provided in this embodiment, the bottom of the base assembly 300 is disposed to be exposed outside the mounting opening 102, and the injection molding main body 420 is injection molded in the space between the outer side surface of the base assembly 300 and the bottom end surface of the liquid storage cup 100, so that the welding area of the seal 400 and the liquid storage cup 100 and the welding area of the seal 400 and the base assembly 300 can be increased, the seal 400 can firmly connect the liquid storage cup 100 and the base assembly 300 together, the gap between the liquid storage cup 100 and the base assembly 300 is further sealed, and since the bottom of the base assembly 300 is exposed outside the mounting opening 102, when the base assembly 300 is assembled on the liquid storage cup 100, the clamping tool such as a manipulator can directly clamp the bottom of the base assembly 300, and then the base assembly 300 is inserted in the mounting opening 102, so that the assembly operation of the base assembly 300 can be simplified, and the operation is simpler.

Optionally, the outer side of the injection molding main body 420 is flush with the outer side of the liquid storage cup 100, and the bottom end surface of the injection molding main body 420 is flush with the bottom end surface of the base assembly 300, so that the joint of the injection molding main body 420 and the liquid storage cup 100 and the joint of the injection molding main body 420 and the base assembly 300 are flat surfaces, so that a user is difficult to find a joint between the injection molding main body 420 and the liquid storage cup 100 and a joint between the injection molding main body 420 and the base assembly 300, the injection molding sealing piece 400 can be prevented from being detached by the user, and further potential safety hazards such as atomized liquid leakage and unqualified injection quality caused by the self-detachment of the user are avoided.
