During assembly, the components in the pump assembly 25 are sequentially assembled according to the sequence shown in fig. 13, then the power unit 2 is assembled according to the structure shown in fig. 4-8, then the liquid outlet pipe 32 is inserted into the first liquid inlet 333 of the inner cover 33, the inner cover 33 is covered on the bottle body 31, finally the conveying part 2552 of the power unit 2 is inserted through the through hole of the bottom cover 14, so that the sealing ring 2561 is positioned between the conveying part 2552 and the through hole of the bottom cover 14, the sealing piece 2562 is positioned in the connecting ring 141 after passing through the through hole of the bottom cover 14, at this time, the inner cover 33 is inserted into the connecting ring 141, the sealing piece 2562 is clamped between the inner cover 33 and the conveying part 2552, the bottle body 31 is rotated, the inner cover 33 is driven to rotate, so that the inner cover rotation connecting part 331 and the bottom cover rotation connecting part 142 are rotatably connected together, the assembly of the atomizer is completed. When the atomized liquid is used up and the liquid storage unit 31 needs to be replaced or the liquid is supplemented, the bottle body 31 only needs to rotate to drive the inner cover 33 to rotate, so that the inner cover rotating connection portion 331 is separated from the bottom cover rotating connection portion 142, the liquid storage unit 31 can be taken down and replaced or supplemented with the liquid, the atomizer is convenient and fast to use and easy to master, and the atomizer is simple in structure and fast to assemble.

This application the atomizer is in the use, and liquid in the body of bottle 31 loops through drain pipe 32, first inlet 333, second inlet 2555 and gets into feed liquor chamber 2558 in, then enlarges through the volume in unfamiliar storehouse, gets into the unfamiliar storehouse in, reduces through the volume in unfamiliar storehouse, gets into out in the liquid chamber 2559, gets into through third liquid inlet 2553, feed liquor pipe 27, fourth inlet 247 in the liquid inlet pool 245, the liquid part that gets into in the liquid pool 245 is atomized by atomizing piece 242, blowout, and remaining liquid gets into through the overflow in the liquid return pool 246, loop through in first liquid return mouth 248, liquid return pipe 28, second liquid return mouth 2554, third liquid return mouth 2556 and the backward flow of fourth liquid return mouth 334 get into in the body of bottle 31. So that the liquid which is never atomized can flow back into the bottle body 31 in time to realize the recovery of the liquid.

As some embodiments of the present application, the first liquid return port 248 and the fourth liquid return port 334 can be directly connected by a pipe, etc., and the remaining liquid in the atomization pool 244 can directly flow back into the bottle body 31 through the first liquid return port 248, the pipe, and the fourth liquid return port 334.

As some embodiments of the present application, the atomizing pool 244 may be a single hollow cavity, the atomizing pool 244 is provided with a fourth liquid inlet 247 and a first liquid return port 248, after the liquid in the atomizing pool 244 is sprayed out from the fourth liquid inlet 247, a part of the liquid contacts the atomizing sheet 242, the atomizing sheet 242 atomizes the liquid, and the remaining liquid flows back to the bottle body 31 through the first liquid return port 248.

As some embodiments of the present application, in the using process, it is found that, since the aperture of the atomizing hole on the atomizing sheet 242 is extremely small, the air pressure in the bottle body 31 is difficult to rapidly balance with the external air pressure, resulting in the problem that the atomizer is prone to having unsmooth air intake, in order to solve the above problem, a plurality of fourth liquid return ports 334 are arranged on the inner cap 33, in the using process, a part of the fourth liquid return ports 334 are used for returning liquid for the liquid to pass through, and the other part of the fourth liquid return ports 334 is used for balancing the air pressure for the gas to pass through, so as to communicate the inside of the bottle body 31 with the external environment. Specifically, the conveying part 2552 is provided with an exhaust channel, the exhaust channel is a through hole, preferably, the exhaust channel is an "L" shaped through hole, the exhaust channel has a first end and a second end, and the first end of the exhaust channel is located on one side of the conveying part 2552 away from the base 2551; the second end is located on the annular side surface of the conveying portion 2552, when the atomizer is assembled, one side of the conveying portion 2552 away from the base 2551 is located in the groove 332 on the inner cover 33, at this time, the first end of the vent channel can communicate with one of the fourth liquid return ports 334 for balancing air pressure, so as to communicate with the inside of the bottle body 31, and at the same time, the second end of the vent channel is located between the bottom cover 14 and the inner cover 33, because a gap is formed between the bottom cover 14 and the inner cover 33, the second end of the vent channel can communicate with the outside atmosphere of the conveying portion 2552, so that during use, external air is conveyed into the bottle body 31 or the air in the bottle body 31 is output to the outside environment, so as to achieve the purpose of keeping the air pressure in the bottle body 31 equal to the external air pressure.

Preferably, two fourth liquid return ports 334 are oppositely arranged on the inner cover 33 for 180 degrees, correspondingly, the first end of the exhaust channel and the third liquid return port 2556 are oppositely arranged on the conveying portion 2552 for 180 degrees, the fourth liquid return port 334 is correspondingly arranged with the inner cover rotating connecting portion 331, the first ends of the second liquid inlet 2555 and the exhaust channel are respectively arranged correspondingly with the bottom cover rotating connecting portion 142, the two fourth liquid return ports 334 are located on a circle with a diameter d, and the first end of the exhaust channel and the third liquid return port 2556 are also located on a circle with a diameter d. At this time, regardless of how the inner cap 33 is rotatably coupled to the connection ring 141, when the inner cap 33 is assembled to the connection ring 141, one fourth liquid return port 334 communicates with the first end of the exhaust passage, and the other fourth liquid return port 334 communicates with the third liquid return port 2556.

More preferably, the first end of the air exhaust channel is separately communicated with one of the fourth liquid return ports 334, and the other fourth liquid return port 334 is separately communicated with the third liquid return port 2556, so that during the use of the atomizer, the backflow liquid which flows back into the bottle body 31 is not in contact with the gas which flows into the bottle body 31 through the air exhaust channel, and the backflow liquid and the gas do not affect each other.

As some examples of the present application, the backflow liquid that flows back into the bottle body 31 may be separated from the gas that flows into the bottle body 31 through the vent channel by providing a barrier between the two fourth liquid return ports 334 on the inner lid 33.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
