The atomizing assembly, the atomizer and the electronic atomizing device of the present application will be described with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of an atomizer according to an embodiment of the present application; FIG. 2 is a schematic cross-sectional view of the atomizer shown in FIG. 1; FIG. 3 is a schematic diagram of the atomizing assembly of the atomizer shown in FIG. 1; fig. 4 is a schematic diagram of an alternative view of the atomizing assembly of the atomizer shown in fig. 1. For the purpose of illustration, only the structures described in connection with the present application are illustrated in the drawings.

An electronic atomizer device according to at least one embodiment of the present application includes a power supply assembly electrically connected to atomizer 100 for providing energy to atomizer 100 for atomizing an aerosolizable medium, and atomizer 100. The medium which can be atomized can be tobacco tar, liquid medicine and other media, and the medium which can be atomized forms aerosol which can be sucked by a user.

Referring to fig. 1 and 2, the atomizer 100 includes a housing 10 and an atomizing assembly 20 disposed in the housing 10. Atomization component 20 is including atomizing seat 21 and the atomizing core that has atomizing chamber 211, and liquid outlet 212 with atomizing chamber 211 intercommunication is seted up at the top of atomizing seat 21, and the top of atomizing seat 21 encloses with the inner wall of casing 10 and closes the stock solution chamber that forms and be used for storing the atomizing medium. The atomizing core is disposed in the atomizing chamber 211 for atomizing the nebulizable medium.

The atomizer 100 further includes a central tube 30 disposed in the housing 10 along the axial direction thereof, the liquid storage chamber is disposed around the central tube 30, and the central tube 30 communicates the atomizing chamber 211 with the outside. In practical use, the nebulizable medium in the liquid storage cavity enters the nebulizing cavity 211 through the liquid outlet 212, and is then adsorbed and nebulized by the nebulizing cartridge. The aerosol formed by the atomization is transported through the central tube 30 to the outside, for example the mouth of the user.

However, when the remaining amount of the nebulizable medium is not large at the later stage of the use of the nebulizer 100, the flowability becomes worse, and the nebulizable medium is difficult to flow into the liquid outlet hole 212 and remains on the top of the nebulizing base 21.

Referring to fig. 2-4, a flow guiding surface 213 is disposed at the top of the atomizing base 21 and slopes downward toward the liquid outlet 212. The fact that the flow guiding surface 213 is arranged inclined with a downward slope towards the exit opening 212 means that the vertical height of the part of the flow guiding surface 213 remote from the exit opening 212 is higher than the vertical height of the part of the flow guiding surface 213 close to the exit opening 212, i.e. the flow guiding surface 213 is configured with a height difference that facilitates the flow of the nebulizable medium towards the exit opening 212.

In practical use, the remaining atomizing medium at the top of the atomizing base 21 can be converted into kinetic energy by means of the flow guide surface 213, and is quickly guided into the liquid outlet hole 212 to enter the atomizing cavity 211 to be atomized by the atomizing core. Therefore, the residual rate of the nebulizable medium is reduced, and the utilization rate of the nebulizable medium is improved.

The sectional shape of the housing 10 along the radial direction thereof is elliptical, and the sectional shape of the atomizing base 21 along the radial direction thereof is elliptical matching the housing 10 so as to be adapted to the housing 10. Thus, the atomizing base 21 has a major axis and a minor axis.

The atomizing assembly 20 further includes a sealing member 23, the sealing member 23 is disposed at the top of the atomizing base 21 in a sealing manner, and the liquid outlet hole 212 is opened on the sealing member 23 and extends into the atomizing chamber 211. Specifically, the sealing member 23 is sealed between the inner surface of the housing 10 and the atomizing base 21, and is used for preventing the nebulizable medium in the liquid storage chamber from leaking from the fit gap between the housing 10 and the atomizing base 21, which affects the user experience. More specifically, the sealing member 23 may be a sealing silicone made of a silicone material, and may be made of other materials, and the present application is not particularly limited as long as the sealing property can be ensured.

It should be noted that, after the sealing element 23 is coupled to the atomizing base 21, the liquid storage cavity is formed by the top of the sealing element 23 departing from the atomizing base 21 and enclosing with the inner wall of the housing 10. The surface of the sealing element 23 facing away from the nebulization seat 21 is configured with a flow guide surface 213. That is, the top of the sealing member 23 facing away from the atomizing base 21 has a flow guiding surface 213 sloping downward towards the outlet opening 212 to prevent residual nebulizable medium.

The liquid outlet holes 212 include two liquid outlet holes arranged at intervals along the long axis direction of the atomizing base 21, and a flow guide surface 213 is uniformly arranged on one side of each of the two liquid outlet holes 212 deviating from each other. Specifically, the liquid outlet holes 212 include two liquid outlet holes located on two sides of the central tube 30, and a flow guiding surface 213 is disposed on a side of each liquid outlet hole 212 away from the central tube 30.

More specifically, the sealing member 23 is provided with a central hole and two liquid outlets 212 penetrating through itself, the central hole is disposed in the middle of the sealing member 23 along the long axis direction of the atomizing base 21, and the two liquid outlets 212 are respectively disposed at two opposite ends of the central hole at intervals along the long axis direction of the atomizing base 21. On the side of each outlet opening 212 facing away from the central tube 30, a flow guide surface 213 is arranged, which slopes downward towards the outlet opening 212.

In the in-service use, the use later stage of atomizer 100, but the atomizing medium remains in one side that two play liquid holes 212 deviate from each other easily, also each goes out one side that liquid hole 212 kept away from center tube 30, has laid a water conservancy diversion face 213 through the one side of keeping away from center tube 30 at each liquid hole 212, will be favorable to remaining in two can the atomizing medium flow direction that go out liquid hole 212 deviate from one side each other go out liquid hole 212 in to reduce can the atomizing medium residual rate, improve can the atomizing medium utilization ratio.

In some embodiments, the guiding surface 213 is located on at least one side of the liquid outlet hole 212 along the long axis direction of the atomizing base 21. Specifically, in some embodiments, the flow guiding surface 213 is located on one side of the liquid outlet hole 212 along the long axis direction of the atomizing base 21, and may also be located on two sides of the liquid outlet hole 212.

It is easy to understand that the originally nebulizable medium mainly remains on one side of the liquid outlet hole 212 along the long axis direction of the nebulizing base 21, and if the flow guide surface 213 is only arranged on one side of the liquid outlet hole 212 along the long axis direction of the nebulizing base 21, the nebulizable medium is likely to remain on the other side without the flow guide surface 213, and therefore, the utilization rate of the nebulizable medium is not high. Therefore, in the preferred embodiment, the guiding surfaces 213 are located on two sides of the liquid outlet hole 212 along the long axis direction of the atomizing base 21.

In some embodiments, the flow guiding surface 213 is located on at least one side of the liquid outlet hole 212 along the short axis direction of the atomizing base 21. In some embodiments, the diversion surface 213 is located on one side of the liquid outlet hole 212 along the short axis direction of the atomizing base 21, or located on both sides of the liquid outlet hole 212.

It is easy to understand that if the flow guide surface 213 is disposed on one side of the liquid outlet hole 212 along the short axis direction of the atomizing base 21, the remaining atomizing medium on the other side without the flow guide surface 213 will be easy to remain, and therefore, the utilization rate of the atomizing medium is not high. Therefore, in the preferred embodiment, the guiding surfaces 213 are located on both sides of the liquid outlet hole 212 along the short axis direction of the atomizing base 21.

It is to be understood that the above description is intended to be illustrative only and is not to be taken as limiting the present application. For example, the flow guiding surface 213 is not limited to be disposed on the side of the liquid outlet 212 along the short axis direction or the long axis direction of the atomizing base 21, and may be disposed at a corresponding position along other directions. Therefore, the guide surface 213 should be set as required in the actual production design process.

In some embodiments, the deflector surface 213 comprises a flat surface, a curved surface, or a combination of flat and curved surfaces. The curved surface may be in the shape of a step, an arc, etc., that is, the guide surface 213 may be not only a plane but also a curved surface in the above-mentioned shape, as long as the liquid can be guided into the liquid outlet hole 212 along the guide surface 213.

In some embodiments, the guiding surface 213 is a plane inclined at a downward slope and forms an angle with the axial direction of the liquid outlet hole 212, and the angle is 0 to 90 degrees. In a preferred embodiment, the included angle is 10 to 30 degrees. It should be noted that the included angle needs to be designed according to actual requirements.

In the atomizing assembly 20, the atomizer 100 and the electronic atomizing device, the top of the atomizing base 21 has the flow guiding surface 213 sloping downward toward the liquid outlet 212. The inclined top of the atomizing base 21 facilitates the remaining residual nebulizable medium to flow towards the exit opening 212 and thus be discharged from the exit opening 212 to the nebulizing chamber 211 at a later stage of use of the nebulizer 100. Therefore, the residual of the nebulizable medium can be reduced, and the utilization rate of the nebulizable medium is improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
