This structural design makes the inner cover 33 only need to rotate 180° to complete the connection with the outer cover 34 or the bottom cover 14 when they are connected.

[0086] Further, the first liquid inlet 333 is located at the center of the inner cover 33, and the fourth liquid return port 334 is oppositely arranged at both sides of the first liquid inlet 333 with an angle of 180°. This structural design makes that when the inner cover 33 is connected with the bottom cover 14, no matter how the inner cover 33 and the bottom cover 14 are rotated and connected, there is always one of the fourth liquid return ports 334 that can be aligned and communicated with the third liquid return port 2256.

[0087] Of course, as long as the inner cover rotating connection part 331 is correspondingly arranged with the fourth liquid return port 334, so that when the inner cover 33 is connected with the bottom cover 14, no matter how the inner cover 33 and the bottom cover 14 are rotated and connected, there is always one of the fourth liquid return ports 334 that can be aligned and communicated with the third liquid return port 2256, the number of the inner cover rotating connection part 331 and the fourth liquid return port 334 can be multiple.

[0088] When assembling, first, according to the order shown in Figure 13 , the components in the pump assembly 25 are sequentially assembled, and then according to the order shown in Figures 4 to 8As shown in the structure, after the power unit 2 is assembled, the liquid outlet pipe 32 is inserted into the first liquid inlet 333 on the inner cover 33, and the inner cover 33 is covered on the bottle body 31. Finally, the delivery part 2552 in the power unit 2 passes through the through hole on the bottom cover 14, so that the sealing ring 2561 is located between the delivery part 2552 and the through hole on the bottom cover 14, and the sealing sheet 2562 passes through the through hole on the bottom cover 14 and is located in the connecting ring 141. At this time, the inner cover 33 is inserted into the connecting ring 141, the sealing sheet 2562 is clamped between the inner cover 33 and the delivery part 2552, the bottle body 31 is rotated to drive the inner cover 33 to rotate, so that the inner cover rotating connection part 331 is rotatably connected with the bottom cover rotating connection part 142, and the assembly of the atomizer is completed. When the atomized liquid is used up, the liquid storage unit 31 needs to be replaced or the liquid needs to be supplemented, only need to rotate the bottle body 31 to drive the inner cover 33 to rotate, so that the inner cover rotating connection part 331 is separated from the bottom cover rotating connection part 142, and the liquid storage unit 31 can be removed for replacement or liquid supplement. The atomizer is not only simple in structure, but also fast in assembly.

[0089] In the use process of the atomizer, the liquid in the bottle body 31 enters the liquid inlet cavity 2558 through the liquid outlet pipe 32, the first liquid inlet 333 and the second liquid inlet 2555 in sequence, then enters the diaphragm chamber through the volume expansion of the diaphragm chamber, enters the liquid outlet cavity 2559 through the volume reduction of the diaphragm chamber, enters the liquid inlet pool 245 through the third liquid inlet 2553, the liquid inlet pipe 27 and the fourth liquid inlet 247. The liquid in the liquid inlet pool 245 is atomized and sprayed by the atomizing sheet 242, and the remaining liquid flows into the liquid return pool 246 through overflow. The liquid that has not been atomized flows into the bottle body 31 through the first liquid return port 248, the liquid return pipe 28, the second liquid return port 2554, the third liquid return port 2556 and the fourth liquid return port 334 in sequence. The liquid that has not been atomized can flow into the bottle body 31 in time, and the liquid is recycled.

[0090] 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 pipeline, and the remaining liquid in the atomizing pool 244 can flow into the bottle body 31 through the first liquid return port 248, the pipeline and the fourth liquid return port 334.

[0091] As some embodiments of the present application, the atomizing pool 244 can be a single hollow cavity, and the fourth liquid inlet 247 and the first liquid return port 248 are arranged on the atomizing pool 244. The liquid in the atomizing pool 244 is sprayed from the fourth liquid inlet 247, part of which contacts the atomizing sheet 242 and is atomized by the atomizing sheet 242, and the remaining liquid flows back to the bottle body 31 through the first liquid return port 248.

[0092] As some embodiments of the present application, it is found in use that due to the extremely small diameter of the atomizing holes on the atomizing sheet 242, the air pressure in the bottle body 31 and the external air pressure are difficult to quickly balance, which causes the atomizer to easily have the problem of poor air intake. To solve the above problem, a plurality of fourth liquid return ports 334 are arranged on the inner cover 33. In use, part of the fourth liquid return ports 334 are used for liquid return, and the other part of the fourth liquid return ports 334 are used for balancing air pressure. Specifically, the conveying part 2552 is provided with an exhaust passage, which is a through hole. Preferably, the exhaust passage is an "L"-shaped through hole. The exhaust passage has a first end and a second end. The first end of the exhaust passage is located on the side of the conveying part 2552 away from the base 2551. The second end is located on the annular side surface of the conveying part 2552. When the atomizer is assembled, the side of the conveying part 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 exhaust passage can be in communication with one of the fourth liquid return ports 334 for balancing air pressure, thereby realizing communication with the inside of the bottle body 31. At the same time, the second end of the exhaust passage will be located between the bottom cover 14 and the inner cover 33. Since the bottom cover 14 and the inner cover 33 have a gap, the second end of the exhaust passage can be in communication with the external atmosphere of the conveying part 2552. In use, external air is transported into the bottle body 31 or the air in the bottle body 31 is output to the external environment, realizing the purpose of keeping the air pressure in the bottle body 31 equal to the external air pressure.

[0093] Preferably, two fourth return liquid ports 334 are oppositely arranged on the inner cover 33, and the first end of the exhaust passage and the third return liquid port 2556 are oppositely arranged on the conveying part 2552. The fourth return liquid port 334 is arranged corresponding to the inner cover rotating connection part 331, and the second liquid inlet port 2555 and the first end of the exhaust passage are arranged corresponding to the bottom cover rotating connection part 142. The two fourth return liquid ports 334 are located on a circle with a diameter of d, and the first end of the exhaust passage and the third return liquid port 2556 are also located on a circle with a diameter of d. At this time, no matter how the inner cover 33 and the connecting ring 141 are connected, when the inner cover 33 and the connecting ring 141 are assembled, one fourth return liquid port 334 is always connected with the first end of the exhaust passage, and the other fourth return liquid port 334 is always connected with the third return liquid port 2556.

[0094] More preferably, the first end of the exhaust passage is individually connected with one of the fourth return liquid ports 334, and the other fourth return liquid port 334 is individually connected with the third return liquid port 2556, so that the return liquid flowing into the bottle body 31 does not contact and affect the gas flowing into the bottle body 31 through the exhaust passage during use of the atomizer.

[0095] As some embodiments of the present application, the return liquid flowing into the bottle body 31 can be separated from the gas flowing into the bottle body 31 through the exhaust passage by arranging a barrier between the two fourth return liquid ports 334 on the inner cover 33.

[0096] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
