FIG. 1 is a schematic view of a nebulizer according to an embodiment of the application; FIG. 2 is a schematic cross-sectional view of the atomizer shown in FIG. 1; FIG. 3 is a schematic view of a partial structure of the atomizer shown in FIG. 1; fig. 4 is a schematic cross-sectional view of the atomizer of fig. 1 from another perspective. For convenience of description, only the structures related to the present application are shown in the drawings.
The electronic atomization device disclosed in at least one embodiment of the present application comprises a power supply assembly and an atomizer 100, wherein the power supply assembly is electrically connected to the atomizer 100, and the atomizer 100 is used for atomizing an nebulizable medium under the action of electric energy provided by the power supply assembly and forming aerosol for a user to inhale.
Referring to fig. 1-2, an atomizer 100 includes a housing 10, an atomizing base 20, and a liquid guide 30. A liquid storage cavity is arranged in the shell 10. The atomizing seat 20 is arranged in the shell 10, and the atomizing seat 20 is provided with a liquid outlet 21. At least part of the liquid guide 30 is disposed in the liquid outlet 21, and is used for guiding the nebulizable medium stored in the liquid storage chamber 11 to flow into the liquid outlet 21.
Specifically, the atomizing base 20 includes an atomizing body 22 and an atomizing core 23. The atomizing body 22 has a mounting cavity therein, and the atomizing core 23 is mounted in the mounting cavity and defines an atomizing cavity with a cavity wall of the mounting cavity. The liquid outlet hole 21 is communicated with the liquid storage cavity 11 and the mounting cavity. In actual use, the nebulizable medium in the liquid storage cavity 11 can enter the installation cavity through the liquid outlet hole 21 and be adsorbed and utilized by the nebulizing core 23.
In some embodiments, the atomizing base 20 further includes a seal 24 coupled to the top of the atomizing body 22 to seal the space between the housing 10 and the atomizing body 22. At this time, the liquid outlet 21 is opened through the sealing member 24 and extends into the installation cavity of the atomizing body 22. Wherein the seal 24 may be a sealing silicone made of a silicone material.
However, in the later stage of use of the atomizer 100, along with the gradual decrease of the nebulizable medium in the liquid storage chamber 11, a part of the nebulizable medium remains on the side of the liquid outlet 21 and cannot enter the liquid outlet 21, so that the residue rate of the nebulizable medium in the liquid storage chamber 11 is high and cannot be fully utilized.
Referring to fig. 3, at least a portion of the liquid guiding member 30 is disposed in the liquid outlet 21, and at least two liquid guiding surfaces 33 are formed on the surface of the liquid guiding member 30 to communicate the liquid storage chamber 11 with the liquid outlet 21. In actual use, the nebulizable medium remaining on the periphery of the liquid outlet 21 can be adsorbed onto the liquid guide surface 33 due to the adsorption force of the liquid guide surface 33, transported into the liquid outlet 21 via the liquid guide surface 33, and then released from the liquid guide surface 33 under the action of gravity, reaches the mounting chamber from the liquid outlet 21, and is adsorbed and nebulized by the nebulizing core 23. Therefore, the residual rate of the nebulizable medium is reduced, and the utilization rate of the nebulizable medium is improved.
Meanwhile, at least part of the liquid guide 30 is made of a lipophilic material, for example, the liquid guide 30 may be made of a plastic material having good lipophilicity, and the plastic liquid guide 30 has a strong suction force on the nebulizable medium, thereby enabling to secure adsorption to the nebulizable medium remaining more on the circumferential side of the liquid outlet hole 21. Of course, the liquid guiding member 30 may be made of other lipophilic materials, which is not particularly limited herein.
Referring to fig. 3-4, in some embodiments, the liquid guide 30 includes a first liquid guide 331 and a second liquid guide 332 that are located on the same side and are connected to each other. In particular, in some embodiments, the first liquid guiding portion 331 is located in the liquid storage cavity 11, and the second liquid guiding portion 332 is located in the liquid outlet 21. In actual use, the residual nebulizable medium in the liquid storage cavity 11 is firstly adsorbed onto the first liquid guiding portion 331, then flows onto the second liquid guiding portion 332 along the first liquid guiding portion 331, and finally drops into the liquid outlet 21 from the second liquid guiding portion 332 under the action of self gravity.
It can be understood that if the first liquid guiding portion 331 and the second liquid guiding portion 332 are disposed in a non-coplanar manner, for example, when the two liquid guiding portions are respectively located in two planes perpendicular to each other, the nebulizable medium on the first liquid guiding portion 331 needs to flow through the connection portion between the first liquid guiding portion 331 and the second liquid guiding portion 332, and then turn to the second liquid guiding portion 332 to enter the liquid outlet 21. In this way, the flow resistance of the nebulizable medium over the liquid guide surface 33 is large, which results in poor actual liquid guide performance of the liquid guide 30.
Therefore, in some embodiments, the first liquid guiding portion 331 and the second liquid guiding portion 332 are located on the same liquid guiding surface, i.e. the first liquid guiding portion 331 and the second liquid guiding portion 332 are located on the same plane. That is, the first liquid guiding portion 331 and the second liquid guiding portion 332 are jointly configured to form a liquid guiding plane, that is, the nebulizable medium on the first liquid guiding portion 331 only needs to directly flow to the second liquid guiding portion 332 in the same plane, and no turning is required between different planes, so that the flow resistance of the nebulizable medium is greatly reduced. In this way, the liquid guiding capability of the liquid guiding member 30 is improved, thereby reducing the residual amount of the nebulizable medium in the liquid reservoir 11.
In some embodiments, the inner wall of the liquid outlet 21 is provided with a groove 211, and the liquid guiding member 30 is partially accommodated in the groove 211, and the liquid guiding member 30 protrudes out of the groove 211 and extends into the liquid storage cavity 11 or the liquid outlet 21, or the liquid guiding member 30 extends into both the liquid storage cavity 11 and the liquid outlet 21. At least two liquid guiding surfaces 33 are formed on the portion of the liquid guiding member 30 located outside the recess 211.
In the preferred embodiment, the liquid guide 30 protrudes from the recess 211 and simultaneously extends into the liquid storage chamber 11 and the liquid outlet 21 to ensure the liquid guide capability of the liquid guide 30. Specifically, the liquid guiding member 30 includes a first protruding portion 31 located in the liquid storage chamber 11 and a second protruding portion 32 located in the liquid outlet hole 21, the first protruding portion 31 and the second protruding portion 32 respectively have a first liquid guiding portion 331 and a second liquid guiding portion 332 located on the same side and connected to each other, and the first liquid guiding portion 331 and the second liquid guiding portion 332 are located on the same liquid guiding surface 33. The first liquid guiding part 331 extending into the liquid storage cavity 11 can absorb residual nebulizable medium at the periphery of the liquid outlet hole 21, and the second liquid guiding part 332 extending into the liquid outlet hole 21 can guide nebulizable medium on the first liquid guiding part 331 into the liquid outlet hole 21.
Further, the first protruding portion 31 and the second protruding portion 32 respectively have at least two first liquid guiding portions 331 and second liquid guiding portions 332 disposed on the same side and connected to each other, and each first liquid guiding portion 331 and a corresponding second liquid guiding portion 332 are located on the same liquid guiding surface 33. In particular, in some embodiments, the first protruding portion 31 has two first liquid guiding portions 331 thereon, and the two first liquid guiding portions 331 are respectively located on two opposite sides along the width direction of the first protruding portion 31. Correspondingly, the second protruding portion 32 has two second liquid guiding portions 332, and the two second liquid guiding portions 332 are respectively located at two opposite sides along the width direction of the second protruding portion 32. The two first liquid guiding portions 331 are connected to the two second liquid guiding portions 332, respectively, and are located on the same liquid guiding surface 33.
In some embodiments, the first protruding portion 31 has a top 335 facing away from the sealing member 24 and a third liquid guiding portion 333 intersecting the top 335, the second protruding portion 32 has a fourth liquid guiding portion 334 facing away from the inner wall of the liquid outlet 21 and connected to the third liquid guiding portion 333, the third liquid guiding portion 333 and the fourth liquid guiding portion 334 are located on the same side, and the top 335, the third liquid guiding portion 333 and the fourth liquid guiding portion 334 are sequentially connected to each other to form another liquid guiding surface 33. In particular to some embodiments, the first projection 31 extends in a radial direction of the exit opening 21 and the second projection 32 extends in an axial direction of the exit opening 21. The top 335 of the first protruding portion 31 and the third liquid guiding portion 333 are arranged at right angles, and the third liquid guiding portion 333 and the fourth liquid guiding portion 334 are arranged in a coplanar manner. The top 335 may be straight or curved, but is preferably straight so as not to interfere with the liquid conducting capacity of the top 335.
In a preferred embodiment, the top portion 335 is disposed at a downward slope toward the third liquid guiding portion 333. In actual use, after the nebulizable medium is sucked onto the top 335, the nebulizable medium can flow along the top 335 to the third liquid guiding portion 333 under the action of its own weight. In this way, the liquid guiding capability of the liquid guiding member 30 can be improved. In a preferred embodiment, the intersection of the top portion 335 and the third liquid guiding portion 333 is rounded. In actual use, when the nebulizable medium on the top 335 flows to the third liquid guiding portion 333, the intersection and connection between the top 335 and the third liquid guiding portion 333 are rounded, so that the flow resistance of the nebulizable medium can be reduced. In this way, the liquid guiding capability of the liquid guiding member 30 can be improved.
In some embodiments, the first protrusion 31 protrudes out of the exit opening 21 in the axial direction of the exit opening 21 by at least 0.1 mm. That is, the first projection 31 is at least 0.1 mm higher than the sealing member 24 in the axial direction of the liquid outlet hole 21. It should be noted that, in theory, the higher the portion of the first protruding portion 31 protruding from the liquid outlet 21, the better the liquid guiding capability of the first protruding portion 31 is. However, in the actual manufacturing process, the height of the first projecting portion 31 should be specifically configured in combination with the use.
Referring to fig. 3, in some embodiments, the housing 10 has an elliptical cross-sectional shape along its radial direction, and the outer contour of the seal 24 also has an elliptical shape that matches the cross-sectional shape of the housing 10 to match the inner surface of the housing 10. The seal 24 is provided with a central bore for the provision of a central tube 60 which communicates between the nebulization chamber and the exterior of the device. The number of the liquid outlet holes 21 includes two, and the two liquid outlet holes 21 are arranged at opposite ends of the central hole at intervals along the long axis direction of the sealing member 24. Therefore, in the later stage of use of the atomizer 100, the nebulizable medium is liable to remain on the sealing member 24 on the side of the two liquid outlet holes 21 facing away from each other. Therefore, when the liquid guide 30 is provided, one liquid guide 30 should be provided in each of the two liquid outlet holes 21, and the respective first protrusions 31 should be provided on the sealing member 24 on the side where the two liquid outlet holes 21 are away from each other. In this way, the nebulizable medium which utilizes the main residual area on the seal 24 can be adsorbed in a targeted manner. It is to be understood that the above is intended to be illustrative only and is not to be construed as limiting the present application. For example, the number of the liquid outlet holes 21 may be one, three, etc., and accordingly, the number of the liquid guiding members 30 may be one, three, etc. For another example, at least two liquid guiding members 30 are disposed in each liquid outlet hole 21, and all liquid guiding members 30 are disposed around the respective liquid outlet hole 21 along the circumferential direction of the respective liquid outlet hole 21. Thus, the possibility that the nebulizable medium remains on the peripheral side of the liquid outlet hole 21 can be more effectively prevented.
The atomizer 100 and the electronic atomization device are provided with the liquid guide member 30, at least part of the liquid guide member 30 is arranged in the liquid outlet hole 21, and at least two liquid guide surfaces 33 are arranged to be communicated with the liquid storage cavity 11 and the liquid outlet hole 21. In the latter stage of use of the atomizer 100, the amount of the nebulizable medium remaining in the reservoir 11 is small, and the nebulizable medium remains on the peripheral side of the liquid outlet 21. The residual nebulizable medium is adsorbed onto the liquid guiding surface 33 due to the adsorption force of the liquid guiding surface 33, is transported into the liquid outlet hole 21 through the liquid guiding surface 33, is separated from the liquid guiding surface 33 under the action of self gravity, and finally reaches the nebulization assembly from the liquid outlet hole 21 to be utilized. Therefore, the residual rate of the nebulizable medium is reduced, and the utilization rate of the nebulizable medium is improved.
Further, each liquid guiding surface 33 includes a first liquid guiding portion 331 and a second liquid guiding portion 332 which are located on the same side and connected. That is, the liquid guiding surface 33 is a plane surface, and has no turn, and the flow resistance to the nebulizable medium is greatly reduced. In this way, the liquid guiding capacity of the liquid guiding member 30 is improved, thereby reducing the residual amount of nebulizable medium in the liquid reservoir 11.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
