Referring to fig. 2, 5 and 6, the on-off valve 400 includes a pulling portion 420 and a blocking portion 410, wherein the pulling portion 420 is in a rod shape, a portion of the pulling portion 420 can pass through the base 230 and is exposed out of the base 230, the blocking portion 410 is in a plate shape, the blocking portion 410 can be slidably connected with the top cover 220 and the base 230, and the pulling portion 420 is used for driving the blocking portion 410 to slide linearly. Specifically, the on-off valve 400 has a first station 11 (see fig. 5) and a second station 12 (see fig. 2), before the atomizer 10 is used, the on-off valve 400 is located at the first station 11, and the blocking portion 410 of the on-off valve 400 can block the liquid guide channel 213, so that the liquid in the liquid storage cavity 151 is prevented from entering the liquid guide channel 213 and leaking out of the atomization core 210, and thus the liquid leakage generated in the storage or transportation process of the whole atomizer 10 is effectively prevented. When the atomizer 10 is in use, a pulling force can be applied to the pulling part 420 to move the on-off valve 400 from the first station 11 to the second station 12, so that the blocking part 410 opens the liquid guide channel 213, and at this time, the liquid in the liquid storage cavity 151 can quickly enter the atomizing core 210 through the liquid guide channel 213 for atomization. The atomizer 10 may be a disposable atomizer 10, and when the on-off valve 400 is positioned at the second station 12, the pulling portion 420 may be pulled apart from the plugging portion 410, and the broken pulling portion 420 may be discarded. In other embodiments, the on-off valve 400 may rotate relative to the atomizing core 210, i.e., the on-off valve 400 is rotatably coupled to the entire atomizing assembly 200, so long as the rotating on-off valve 400 can open or block the fluid passage 213.
In some embodiments, on the material, the liquid barrier 300 may be liquid barrier cotton, which may be nonwoven fabric with a composition of plant fibers, organic cotton, ecological cotton, and the like. The liquid-proof cotton has good air permeability, so that gas can pass through the liquid-proof cotton from one side of the liquid-proof cotton and enter the other side of the liquid-proof cotton; meanwhile, the liquid-proof cotton has good liquid absorption, namely, the liquid-proof cotton has strong absorption effect on liquid, so that the liquid cannot flow through the liquid-proof cotton from one side of the liquid-proof cotton and flow into the other side of the liquid-proof cotton, and the blocking function of the liquid-proof cotton on the liquid flow is ensured. In shape, the spacer 300 may have a plate-like structure.
Referring to fig. 2 to 6, the flange 212 is provided with a through hole 214, the base 230, the top cover 220 and the atomizing core 210 enclose an atomizing chamber 235, the through hole 214 forms a part of the atomizing chamber 235, and the atomizing core 210 can flow the atomized smoke from the liquid through the atomizing chamber 235 from the air suction channel 140. The nebulization chamber 235 communicates with both the suction channel 140 and the air flow channel 160. The spacer 300 is provided with a mounting hole 310, and the body 211 of the atomizing core 210 is inserted into the mounting hole 310 to position the mounting of the spacer 300. The flange 212 is pressed against the inner side of the spacer 300, and the first mounting portion 231 of the base 230 is pressed against the outer side of the spacer 300, that is, the spacer 300 is sandwiched between the flange 212 and the first mounting portion 231, and at this time, the spacer 300 can close the port of the through hole 214 away from the atomizing chamber 235.
The first mounting portion 231 is provided with a first through hole 233 and a second through hole 234, the first through hole 233 can be communicated with the liquid storage cavity 151, and the first through hole 233 and the atomizing cavity 235 together form a ventilation channel 201. The end portion of the body 211 of the atomizing core 210 may be inserted into the second through hole 234, and the second through hole 234 plays a good role in positioning the installation of the atomizing core 210, and meanwhile, the liquid in the liquid storage cavity 151 may enter the liquid guide channel 213 from the second through hole 234. When the on-off valve 400 is at the first station 11, the blocking portion 410 of the on-off valve 400 blocks the second through hole 234, so as to prevent the liquid in the liquid storage cavity 151 from entering the liquid guide channel 213 through the second through hole 234. When the on-off valve 400 is at the second station 12, the blocking portion 410 of the on-off valve 400 opens the second through hole 234, so that the liquid in the liquid storage cavity 151 smoothly passes through the second through hole 234 and enters the liquid guide channel 213, and the solid arrows in fig. 2 are the flow directions of the liquid.
Since the liquid separating member 300 seals the port of the through hole 214 far from the atomizing chamber 235, the liquid in the liquid storage chamber 151 cannot flow through the liquid separating member 300 and enter the through hole 214 through the second through hole 234, so that the liquid is prevented from blocking the whole ventilation channel 201, further the liquid is prevented from entering the atomizing chamber 235, the air flow channel 160 and the air suction channel 140, and the gas flowing in from the air flow channel 160 is ensured to quickly enter the liquid storage chamber 151. Meanwhile, the flange portion 212 has a larger contact area with the liquid barrier 300, and the liquid adsorbed on the liquid barrier 300 can be absorbed by the flange portion 212 so as to be atomized, so that the liquid absorbing capacity of the liquid barrier 300 is timely released, and the long-term use of the liquid barrier 300 is ensured and the liquid flow blocking function is exerted.
During the pumping process, the liquid is consumed as it is continuously atomized, so that the liquid in the liquid storage chamber 151 is reduced and the space of the liquid storage chamber 151 is released. At this time, the external gas may sequentially enter the liquid storage cavity 151 through the gas flow channel 160, the atomizing cavity 235, the through hole 214, the liquid isolation member 300 and the first through hole 233, the dotted arrow in fig. 2 is the flow direction of the gas, the gas fills the space where the liquid does not exist in the liquid storage cavity 151, the gas filling can effectively increase the gas pressure in the liquid storage cavity 151, the gas pressure acts on the residual liquid in the liquid storage cavity 151, the liquid storage cavity 151 is ensured to smoothly supply the liquid to the atomizing core 210, the defect of insufficient liquid supply caused by vacuum or negative pressure in the liquid storage cavity 151 of the atomizing core 210 is avoided, and the scorched smell affecting the suction experience due to insufficient liquid supply is prevented.
Therefore, by providing the ventilation channel 201 and fully utilizing the good ventilation performance of the liquid isolation member 300, it is ensured that the external air enters the liquid storage cavity 151 through the air flow channel 160, the ventilation channel 201 and the liquid isolation member 300, so that the negative pressure generated by the vacuum in the liquid storage cavity 151 is avoided, the liquid in the liquid storage cavity 151 can smoothly flow into the atomization core 210, and the burning phenomenon of the atomization core 210 due to insufficient liquid supply is prevented. At the same time, the good liquid absorbing function of the liquid separating member 300 is fully exerted, the liquid in the liquid storage cavity 151 is prevented from filling the whole ventilation channel 201 to form a blocking effect on the gas flow, and the gas flowing in from the gas flow channel 160 is ensured to quickly enter the liquid storage cavity 151. The liquid separating member 300 has better liquid storage and liquid guide functions, when the liquid supply on the atomization core 210 is insufficient or the liquid separating member 300 is full of liquid, the liquid absorbed and stored by the liquid separating member 300 is conducted to the atomization core 210 due to the proximity of the liquid separating member 10, so that the liquid guide efficiency is improved, and the scorching possibly caused by the insufficient liquid supply is relieved.
In some embodiments, the top cover 220 is provided with a fixing hole 222, the fixing hole 222 is communicated with the atomizing chamber 235, and the end of the inserting portion 120 is matched with the fixing hole 222, so that the fixing hole 222 is communicated with the air suction channel 140. The sealing member 500 may be a sealing ring, and the sealing ring is embedded on the second mounting portion 232 of the base 230, when a part of the second mounting portion 232 is matched with the accommodating cavity 150, the sealing ring is pressed between the second mounting portion 232 and the inner wall surface of the housing portion 110, and the sealing member 500 may play a role in sealing, so as to prevent the liquid in the liquid storage cavity 151 from leaking from the gap between the second mounting portion 232 and the housing portion 110.
