Referring to fig. 4 and 5, the atomizing base 20 is further provided with an air vent 23, the air vent is configured to communicate with the liquid storage cavity 12, and specifically, the air vent 23 is used for supplying air into the liquid storage cavity 12 to maintain the air pressure balance in the liquid storage cavity 12; the outer side walls of the atomizing base 20 and the base 40 are provided with air guide grooves 25, the air guide grooves 25 are communicated with the atomizing cavity 24 and the air guide holes 23, so that air in the atomizing cavity 24 can be supplied to the liquid storage cavity 12 through the air guide grooves 25 and the air guide holes 23, and the air pressure balance in the liquid storage cavity 12 is maintained; wherein, the fluid flowing path of the air guide groove 25 is further provided with a liquid blocking structure 26, and the liquid blocking structure 26 is used for storing condensate flowing through or towards the air guide groove 25. It will be appreciated that in one embodiment, the air guide slots 25 may be provided only on the outer side wall of the atomizing base 20 or the base 40. Therefore, the structure is not particularly limited as long as the gas can be guided.

Specifically, when the atomizer 100 works, the atomizing core 30 continuously consumes the liquid stored in the liquid storage cavity 12, and then the air pressure in the liquid storage cavity 12 is reduced due to the reduction of the liquid, and the too low air pressure in the liquid storage cavity 12 will cause difficulty in discharging the liquid from the atomizing core 30, so that the liquid supply to the atomizing core 30 is insufficient, the atomizing core 30 is easily dried to generate scorched smell, and the like, which is harmful to the service life and quality of the atomizer 100.

Through setting up air guide hole 23 and air guide groove 25 to intercommunication atomizing chamber 24 and stock solution chamber 12, then when stock solution intracavity 12 internal gas pressure was low, accessible air guide hole 23 and air guide groove 25 are to stock solution intracavity 12 internal gas supply, in order to maintain the atmospheric pressure in stock solution chamber 12, thereby can avoid leading to the situation emergence of the confession liquid inadequately to atomizing core 30 because of the atmospheric pressure in stock solution intracavity 12 is low.

Further, as shown in fig. 6, a liquid blocking structure 26 is disposed on a fluid flowing path of the air guide groove 25, and the liquid blocking structure 26 is used for storing condensate flowing through or towards the air guide groove 25 to prevent the condensate from blocking the air guide hole 23 and the air guide groove 25.

Specifically, when the user finishes smoking, high-temperature smoke remains in the atomizing cavity, and when the high-temperature smoke flows into the air guide groove 25, the smoke is condensed to form condensate due to heat absorption, so that the air supply channel leading to the liquid storage cavity 12 is easily blocked.

In order to solve the problem, a liquid blocking structure 26 is arranged on a fluid flowing path of the air guide groove 25 to store condensate in the air guide groove 25, so that the condition that air is not smoothly supplied to the liquid storage cavity 12 due to the fact that the condensate blocks the air guide hole 23 and the air guide groove 25 is avoided; wherein the smoke is convenient to condense and store in the liquid blocking structure 26, and the liquid condensed in the air guide groove 25 flows into the liquid blocking structure 26 to store.

Liquid blocking structure 26 may be disposed at the leading end, trailing end, or midway between the leading and trailing ends of the path of fluid flow through gas guide slots 25. For example, the liquid blocking structure 26 is disposed at the head end of the fluid flowing path of the air guide groove 25, that is, two ends of the liquid blocking structure 26 are respectively communicated with the atomizing chamber 24 and the air guide groove 25; or, the liquid blocking structure 26 is disposed at the tail end of the fluid flowing path of the air guide groove 25, that is, two ends of the liquid blocking structure 26 are respectively communicated with the air guide hole 23 and the air guide groove 25; alternatively, the liquid blocking structure 26 is disposed in the middle between the head and the tail of the fluid flowing path of the air guide groove 25, i.e., the fluid flowing path of the air guide groove 25 passes through the liquid blocking structure 26.

For example, two liquid blocking structures 26 are provided, and two liquid blocking structures 26 are respectively provided at the head end and the tail end of the fluid flow path of the air guide groove 25.

When the number of the liquid-blocking structures 26 is plural, the structures of the plural liquid-blocking structures 26 may be the same or different. The liquid blocking structure 26 may be a trough structure for storing condensate. The liquid blocking structure 26 can also be a liquid absorbing part, which can be a component capable of absorbing and storing liquid such as liquid absorbing cotton, liquid absorbing paper and the like, and the liquid absorbing part is provided with a pore passage communicated with the air guide groove 25 so as to facilitate air transmission; alternatively, the liquid absorbing member may be disposed at one side of the air guide groove 25, and one side surface of the liquid absorbing member may be in contact with the air guide groove 25, so that the condensate flowing through the air guide groove 25 may be stored.

For example, when the number of the liquid blocking structures 26 is plural, the plural liquid blocking structures 26 may be all of a groove structure, a liquid absorbing member, or the like, and the plural liquid blocking structures 26 may include a groove structure, a liquid absorbing member, or the like.

In other words, by using the large liquid storage space of the liquid storage tank 260 so that the condensate is stored in the liquid storage tank 260, even when the air guide tank 25 is partially clogged with the condensate, the air pressure can push the condensate to flow into the liquid storage tank 260, thereby releasing the clogging state.

Specifically, the condensate is stored using the width and depth difference between the reservoir 260 and the air guide channel 25, thereby preventing the condensate from clogging the air guide channel 25.

In other embodiments, the air-guide tank 25 and the liquid storage tank 260 may be located at approximately the same level, with the air-guide holes 23 higher than the air-guide tank 25 and the liquid storage tank 260.

As shown in fig. 5, in this embodiment, the air guide groove 25 is arranged on the outer walls of the base 40 and the atomizing base 20 in a roundabout manner, so as to increase the length of the air guide groove 25, and facilitate the air flow cooling through the air guide groove 25, thereby playing a role of heat insulation, storing more air quantity, facilitating the diffusion of the smoke to the air guide groove 25, relatively reducing the condensation quantity of the smoke in the atomizing cavity 24, facilitating the reduction of the effusion of the atomizing cavity 24, and reducing the risk of liquid absorption from the atomizing cavity 24 by the leakage of the atomizer 100 and the oral cavity of the user.
