However, in the atomizer on the market, after the atomized liquid is heated and atomized, condensate is easily generated in the gas outlet channel. Among these, the reasons for the generation of condensate are generally as follows: 1. the temperature difference exists between the atomized high-temperature smoke and the inner wall of the gas outlet channel, so that the atomized high-temperature smoke can be condensed into small liquid drops on the inner wall of the gas outlet channel; 2. the small liquid drops have different sizes, when the atomizer works and a user sucks the atomizer through the mouth, the air pressure in the air outlet channel is smaller than the air pressure in the oil cavity, namely the air pressure in the air outlet channel is in a negative pressure state, so that small condensed liquid drops hanging on the inner wall of the air outlet channel are easy to be sucked to the outlet of the atomizer along with smoke and gas and climb upwards from the inner wall of the air outlet channel, and even can directly enter the oral cavity of the user at times to influence the sucking experience of the user; 3. the atomizing core can produce the liquid drop when the working temperature difference is too big and explode and split, and some large granule condensate drops can be by direct splash to the gas outlet duct inner wall.

As shown in fig. 1 to 7 and 13 to 18, an atomizer according to an embodiment of the present invention includes: a suction nozzle 214, an outer housing 11, an inner housing 102, a reservoir 1 and a transition piece 2. Wherein, the inner side wall of the inner shell 102 is provided with a first channel 121 and a second channel 122 around the inner side wall along the axial direction of the atomizer. The first channel 121 has a first end 1211, the second channel 122 has a second end 1222, the first end 1211 and the second end 1222 are in communication with each other, and the first end 1211 and the second end 1222 (shown in fig. 7) are both located away from the nozzle 214. That is, one end of the first passage 121 and one end of the second passage 122 are provided with the suction nozzle 214, and the other end of the first passage 121 and the other end of the second passage 122 (i.e., the first end 1211 and the second end 1222) communicate with each other. It is understood that the suction nozzle 214 is disposed opposite to the end of the first and

second channels

121, 122 that communicates with each other.

Wherein, the liquid storage bin 1 is arranged between the inner side wall of the outer shell 11 and the outer side wall of the inner shell 102, and a liquid storage cavity 111 for storing atomized liquid is formed in the liquid storage bin 1. Alternatively, the reservoir 1 may be a single reservoir body having the reservoir chamber 111 separately disposed between the inner sidewall of the outer housing 11 and the outer sidewall of the inner housing 102.

The converter 2 is provided with a third channel 211 and a fourth channel 212. Wherein, the third channel 211 and the fourth channel 212 are arranged independently, one end of the third channel 211 is an air inlet hole 217 opened on the outer wall of the converter 2 (the outer wall is not limited to the circumferential outer wall of the converter 2, and can also be the end side wall of the converter 2), the converter 2 is rotatably arranged between the suction nozzle 214 and the top side of the liquid storage bin 1 (it can be understood that the first channel 121 and the second channel 122 are arranged inside the liquid storage bin 1 in a penetrating manner), and the suction nozzle 214 is communicated with the fourth channel 212, so that the converter 2 changes the flow state and/or the flow path of the air by rotating relatively with the liquid storage bin 1.

Specifically, the converter 2 can rotate a certain angle around the axis of the atomizer, and rotate relative to the reservoir 1 located below the converter 2 to switch the flow path of the gas, and the conversion state of the gas can also be switched when the converter 2 rotates relative to the reservoir 1 along the axis of the atomizer.

It should be noted that, when the converter 2 rotates around the axis of the atomizer, the suction nozzle 214 can rotate synchronously with the converter 2, and the reservoir 1 is stationary, i.e. the suction nozzle 214 and the converter 2 are fixed to each other, so that when the converter 2 rotates, the suction nozzle 214 can also rotate synchronously with the converter 2, wherein the rotation of the suction nozzle 214 and the converter 2 is based on the reservoir 1, i.e. the suction nozzle 214, the converter 2 and the reservoir 1 rotate relatively.

Of course, the converting element 2 can also be rotated relative to the suction nozzle 214, while the reservoir 1 is still stationary. That is, the suction nozzle 214 and the converter 2 are connected by an adapter device, which can be fixed on the top side of the reservoir 1, and the converter 2 is disposed in the adapter device and rotatably connected to the reservoir 1, at this time, the suction nozzle 214 is fixed on the adapter device, so that when the converter 2 rotates, the adapter device fixed with the reservoir 1 and the suction nozzle 214 are also fixed because the reservoir 1 is fixed, that is, the converter 2 rotates relative to the suction nozzle 214 and the reservoir 1. The conversion member 2 may be an adjusting ring, and the adapter member may be a mounting seat for mounting the suction nozzle 214 and the adjusting ring, which is not limited herein.

In this embodiment, there are two types of gas flow states: one is an air passage locking state, and the other is an air passage communicating state. The airway lock state is that the converter 2 rotates to a state that the air can not pass through the communicated channel, namely, the air can not enter from the air inlet hole 217 and can not be sucked into the mouth of the user from the suction nozzle 214, namely, the airway is closed; on the contrary, the air passage is connected, that is, the converter 2 is rotated to a state that air can enter from the air inlet hole 217 and be sucked from the suction nozzle 214 into the user's mouth, that is, the air passage is opened. That is, the switching member 2 can be switched from the air passage locking state to the air passage communicating state, or from the air passage communicating state to the air passage locking state.

In this embodiment, the meaning of the conversion member 2 changing the gas flow state and/or the gas flow path by rotating relative to the liquid storage tank 1 includes the following cases:

1. the relative rotation of the converter 2 can switch the gas flow path, for example, the inlet channel can be switched to the outlet channel, and the outlet channel can be switched to the inlet channel.

2. By the relative rotation of the switching member 2, as described above, the gas flow state can be switched, i.e., the switching member 2 can be switched from the gas passage locking state to the gas passage communicating state, or from the gas passage communicating state to the gas passage locking state.

3. By the relative rotation of the conversion member 2, as described above, the state of communication of the gas passages can be adjusted in the state of communication of the gas passages, for example, the outlet gas passages and the inlet gas passages become narrower as they become narrower; alternatively, the outlet and inlet channels may become larger.

In the embodiment of the present invention, the switching element 2 may be rotated to simultaneously change the gas flow state and the gas flow path, or may be rotated to independently change the gas flow state and the gas flow path. For ease of understanding, referring to fig. 2-6, the following is illustrated:

when the air passage is in the complete communication state and the air flow path is the third channel 211, the first channel 121, the second channel 122 and the fourth channel 212 in sequence (as shown in fig. 5, the path I is the air flow path, and the path J is the atomized liquid flow path), that is, when the third channel 211 and the first channel 121 are used as the air inlet channel 200 and the fourth channel 212 and the second channel 122 are used as the air outlet channel 100, the converter 2 slowly rotates around the axis of the atomizer in one direction, and at this time, the air inlet channel 200 and the air outlet channel 100 both gradually narrow, that is, the air passage changes from the complete communication state to the incomplete communication state. It can be understood that only the gas flow state is changed, namely, the gas passage is changed from the complete communication state to the incomplete communication state. The fourth channel 212, the second channel 122, the third channel 211, the first channel 121 and the channel 4 can be regarded as a path I, that is, a path through which an air flow circulates, the third channel 211 and the first channel 121 are mainly flow paths for outside air, and the channel 4, the fourth channel 212 and the second channel 122 are flow paths for a mixture gas of an atomized liquid and outside air.

Continuing to rotate the converter 2 in the same direction, the air inlet passage 200 and the air outlet passage 100 are completely closed, i.e. the air passage changes from the incomplete communication state to the air passage locking state (as shown in fig. 4); that is, the gas flow state is switched at this time. It can be understood that only the gas flow state is changed, namely, the gas passage communication state is changed into the gas passage locking state.

Then, the converter 2 is rotated continuously in the same direction, the third channel 211 and the second channel 122 are connected to each other, at this time, the second channel 122 and the third channel 211 are connected to each other to form the inlet channel 200, and the fourth channel 212 and the first channel 121 are connected to each other, that is, the first channel 121 and the fourth channel 212 are connected to each other to form the outlet channel 100 (as shown in fig. 6). At this time, it can be understood that not only the gas flow state is changed from the gas passage blocked state to the gas passage connected state, but also the gas flow path is changed, and the second passage 122, which was previously a part of the outlet passage 100, now becomes a part of the inlet passage 200, and the first passage 121, which was previously a part of the inlet passage 200, now becomes a part of the outlet passage 100. At this time, it can be understood that the converter 2 and the reservoir 1 rotate relative to each other, and the gas flow state and the gas flow path are changed in synchronization with each other.

When the conversion member 2 is further rotated in the same direction, the inlet passage 200 and the outlet passage 100 are larger and larger until the third passage 211 and the second passage 122 are completely communicated and the fourth passage 212 and the first passage 121 are also completely communicated, and the air passage is changed from the incomplete communication state to the complete communication state. The gas flow path is sequentially changed to a third channel 211, a second channel 122, a first channel 121, and a fourth channel 212 (as shown in fig. 6). In this case, it can be understood that the relative rotation of the converter 2 only changes the gas flow state.

And the conversion piece 2 is continuously rotated towards the same direction, the air passage is changed from the complete communication state to the incomplete communication state, the conversion piece 2 is continuously rotated, and the gas circulation state is changed from the incomplete communication state to the air passage locking state.

The converter 2 may rotate clockwise or counterclockwise, and the rotation direction may be not limited to one direction to change the gas flow state and the gas flow path.

Based on the above examples, the gas flow state will be further described below. Referring to fig. 4 again, in the airway lock state, the converter 2 rotates to a state where the first channel 121 and the second channel 122 are respectively staggered from the third channel 211 and the fourth channel 212. That is, neither of the first and

second passages

121 and 122 communicates with either of the third and

fourth passages

211 and 212.

In the air passage communication state, the converter 2 rotates until the first passage 121 at least partially communicates with the third passage 211 and the second passage 122 at least partially communicates with the fourth passage 212 (as shown in fig. 5). The external air enters the third channel 211 through the air inlet holes 217, the first channel 121 is communicated with the third channel 211 to form an air inlet channel 200, and the second channel 122 and the fourth channel 212 form an air outlet channel 100.

In the air passage communication state, the switching of the air flow path is realized by rotating the converter 2 until the first passage 121 at least partially communicates with the fourth passage 212, and the second passage 122 at least partially communicates with the third passage 211, the communicated first passage 121 and fourth passage 212 forming the air outlet passage 100, and the second passage 122 and third passage 211 forming the air inlet passage 200 (as shown in fig. 6). It can be understood that any one of the first channel 121 and the second channel 122 can be switched to the air inlet channel 200 or the air outlet channel 100 by the rotation of the converting element 2, that is, any one of the first channel 121 and the second channel 122 and the channel where the air inlet hole 217 is located are communicated with each other (in this embodiment, the air inlet hole 217 is provided on the outer wall of the third channel 211. of course, in other embodiments, the air inlet hole 217 may also be provided on the outer wall of the fourth channel 212), that is, the air inlet channel 200 can be used, and the other channel can be used as the air outlet channel 100 because the other channel is communicated with the suction nozzle 214.

During the use process of a user, the atomized smoke contacts the inner wall of the air outlet channel 100 with a low temperature to generate condensed liquid hanging on the wall, so that the air outlet channel and the air inlet channel are switched through the conversion part 2, the former air outlet channel 100 is switched into the air inlet channel 200, and the former air inlet channel is switched into the air outlet channel 100 at the same time. Thus, the wall-hung condensate enters the atomizing assembly 3 in the technical scheme described below along with the inlet airflow to be atomized again due to the fact that the outlet passage 100 is switched to the inlet passage 200, and the smoke enters the mouth of the user through the outlet passage 100 after the inlet passage 200 is switched. And when having the condensate wall built-up and during the inner wall of air outlet channel 100 again, reverse air inlet channel 200 and air outlet channel 100 once more, the condensate flows through atomization component 3 through the air inlet stream once more, and the air outlet channel 100 after the reversal flows out after atomizing, so circulation is reciprocal, can prevent effectively that the inside condensate of air flue from getting into user's oral area, has promoted user's absorption and has experienced.

As can be seen from the above, if the inlet channel 200 in the complete communication state is reversely switched to the outlet channel 100 in the complete communication state, and at the same time, the outlet channel 100 in the complete communication state is reversely switched to the inlet channel 200 in the complete communication state, the converting element 2 just needs to rotate 180 degrees.
