[0029] See also Figure 1-4 The embodiment of the utility model provides a base for an atomizer, the base comprising: a first section 1 and a second section 2 arranged in a lateral interval and connected; and the bottom wall of the first section 1 and the bottom wall of the second section 2 have a height difference along the axial direction; the bottom wall of the first section 1 is convexly provided with at least one first protrusion 11, and the bottom wall of the second section 2 is convexly provided with a plurality of second protrusions 21 distributed at preset intervals; the condensate flows to the first section 1 and the second section 2.

[0030] In the embodiment of the utility model, the base includes a first section 1 and a second section 2, and the condensate can flow to the first section 1 and the second section 2. At least one first protrusion 11 is protruded on the bottom wall of the first section 1, so that under the action of the surface tension of the liquid, at least part of the condensate flowing to the first section 1 adheres to the first protrusion 11, and the condensate is locked on the first protrusion 11, so that the flow of the condensate can be controlled, and the condensate is locked in the first section 1. Similarly, a plurality of second protrusions 21 are protruded on the bottom wall of the second section 2 at intervals, and under the action of the surface tension of the liquid, a large amount of condensate flowing to the second section 2 adheres to the plurality of second protrusions 21, and the condensate is locked on the second protrusions 21, so that the flow of the condensate can be controlled, and the condensate is locked in the second section 2. In addition, the second protrusions 21 are arranged at a preset spacing, so that the distance between the second protrusions 21 is small, and the small gap between two adjacent second protrusions 21 can control the flow of condensate, so that the condensate that is not adsorbed on the second protrusions 21 can be well stored between any two adjacent second protrusions 21, further realizing the locking of the condensate in the second interval 2. The embodiment of the utility model can increase the adsorption of condensate by setting the first protrusion 11 in the first interval 1 and the second protrusion 21 in the second interval 2, and setting the spacing of the second protrusions 21, so that at least part of the condensate is locked in the first interval 1, and a large amount of condensate is locked in the second interval 2, that is, more condensate is gathered in the first interval 1 and the second interval 2, thereby improving the anti-leakage effect of the atomizer. It is also possible to eliminate the oil-absorbing cotton, save costs, and reduce the fibrous substances produced by the cotton in the airway being inhaled along with the aerosol to produce health effects.

[0031] In addition, if Figure 4 As shown, in the coordinate system, the X axis represents the horizontal direction and the Y axis represents the axial direction.

[0032] Furthermore, in some embodiments, the distance between two adjacent second protrusions 21 is 0.35-0.5 mm.

[0033] Specifically, a plurality of second protrusions 21 are protruded on the bottom wall of the second section 2 in an array, and the distance between two adjacent second protrusions 21 can be 0.35, 0.36, 0.37, 0.38, 0.39, 0.4, 0.42, 0.45, 0.48, 0.5 mm, etc., so that the distance between two adjacent second protrusions 21 is small enough, and the tiny gap can control the flow of condensate, so that the condensate not adsorbed on the second protrusions 21 can be well stored between any two adjacent second protrusions 21, thereby achieving the locking of the condensate in the second section 2.

[0034] In some embodiments, the plurality of second convex pillars 21 are arranged in an array so that the distance between any two second convex pillars 21 is equal. In some embodiments, the plurality of second convex pillars 21 may also be arranged irregularly, and the distance between any two second convex pillars 21 may be equal or unequal.

[0035] Further, in some embodiments, the diameter of the first protrusion 11 is 0.6-0.8 mm, and / or the diameter of the second protrusion 21 is 0.6-0.8 mm.

[0036] Specifically, the diameter of the first protrusion 11 can be 0.6, 0.62, 0.65, 0.68, 0.7, 0.72, 0.75, 0.8 mm; the diameter of the second protrusion 21 can be 0.6, 0.62, 0.65, 0.68, 0.7, 0.72, 0.75, 0.8 mm, and the diameters of the first protrusion 11 and the second protrusion 21 can be the same or different. In addition, in the first section 1, the diameters of the plurality of first protrusions 11 can be the same or different; in the second section 2, the diameters of the plurality of second protrusions 21 can be the same or different. By reducing the diameters of the first protrusion 11 and the second protrusion 21, more first protrusions 11 and / or second protrusions 21 can be added in the same space, so that the contact area between the first protrusion 11 and the condensate can be increased as a whole, the contact area between the second protrusion 21 and the condensate can be increased, and the adsorption capacity of the first protrusion 11 and the second protrusion 21 for the condensate can be improved.

[0037] It is understandable that in some embodiments, the diameter of the first protrusion 11 can be adjusted according to the size of the first section 1 and the difficulty of manufacturing, that is, the diameter of the first protrusion 11 can be less than 0.6 mm or greater than 0.8 mm. In addition, in some embodiments, the spacing between the second protrusions 21 and the diameter of the second protrusion 21 can be comprehensively adjusted according to the size of the second section 2 and the difficulty of manufacturing.

[0038] Furthermore, in some embodiments, a plurality of capillary grooves 3 are formed on the bottom wall of the first section 1 , and / or a plurality of capillary grooves 3 are formed on the bottom wall of the second section 2 .

[0039] Specifically, if the bottom wall of the first interval 1 is provided with a capillary groove 3, the condensate in the first interval 1 can also be stored in the capillary groove 3 under the capillary adsorption force of the capillary groove 3, further improving the ability of the first interval 1 to adsorb the condensate. Similarly, if the bottom wall of the second interval 2 is provided with a capillary groove 3, the condensate in the second interval 2 is stored in the capillary groove 3 under the action of the capillary adsorption force, further improving the ability of the second interval 2 to adsorb the condensate.

[0040] Furthermore, in some embodiments, the width of the capillary groove 3 is 0.2-0.35 mm, and the depth of the capillary groove 3 is 0.3-0.5 mm.

[0041] Further, the width of the capillary groove 3 can be 0.2, 0.21, 0.22, 0.23, 0.24, 0.25, 0.28, 0.3, 0.32, 0.35 mm, etc., and the depth of the capillary groove 3 can be 0.3, 0.32, 0.35, 0.38, 0.4, 0.42, 0.45, 0.48, 0.5 mm, etc. While ensuring the simplicity of processing, the capillary groove 3 can also have a strong capillary force.

[0042] Further, in some embodiments, at least two first protrusions 11 are protruded from the bottom wall of the first interval 1, a capillary groove 3 is provided between two adjacent first protrusions 11, and at least one capillary groove 3 is provided between the first protrusion 11 adjacent to the side wall of the first interval 1 and the side wall of the first interval 1; and / or, a capillary groove 3 is provided between two adjacent second protrusions 21, and at least one capillary groove 3 is provided between the second protrusion 21 adjacent to the side wall of the second interval 2 and the side wall of the second interval 2.

[0043] In some specific embodiments, the first interval 1 includes at least two first protrusions 11, and capillary grooves 3 can be set between the two first protrusions 11 and between the first protrusions 11 and the side walls of the first interval 1. Therefore, condensation liquid that is not adsorbed on the first protrusions 11 and the side walls of the first interval 1 can be stored in the capillary grooves 3.

[0044] In some specific embodiments, the plurality of second protrusions 21 of the second interval 2 are arranged in an array, and a capillary groove 3 is connected between two adjacent second protrusions 21, so that the capillary grooves 3 can also be arranged in an array, and for the second protrusions 21 adjacent to the side walls of the second interval 2, the capillary grooves 3 can also be provided between the second protrusions 21 and the side walls of the second interval 2, so that the condensate that is not adsorbed on the second protrusions 21 and the side walls of the second interval 2 can be stored in the capillary grooves 3.

[0045] Furthermore, in some embodiments, a guide slope 4 is provided between the first section 1 and the second section 2 , which slopes from the second section 2 toward the first section 1 .

[0046] Specifically, since the oil trapping capacity (ability to lock condensate) of the second interval 2 is stronger than that of the first interval 1, by providing a guide slope 4 between the first interval 1 and the second interval 2, the condensate flowing in the first interval 1 (unadsorbed condensate) can flow directly to the second interval 2 through the guide slope 4, so that the flowing condensate can be adsorbed by the multiple second protrusions 21 of the second interval 2, and can also be adsorbed by the multiple capillary grooves 3 of the second protrusions 21, and the condensate can also be controlled by the tiny gap between two adjacent second protrusions 21, so that the leakage-proof effect of the entire device can be achieved.

[0047] In some embodiments, the bottom wall of the first section 1 is higher than the bottom wall of the second section 2 , and one end of the guide slope 4 is connected to the bottom wall of the first section 1 and the other end is connected to the bottom wall of the second section 2 .

[0048] Specifically, the first section 1 and the second section 2 are arranged in a staggered manner in the transverse direction and in the axial direction, and the two are connected by the inclined guiding slope 4. In the first section 1, the condensate that is not adsorbed on the first protrusion 11 and the capillary groove 3 flows on the bottom wall of the first section 1 and directly flows to the second section 2 under the guidance of the guiding slope 4 and the action of gravity, and does not stay in the first section 1, which can prevent the condensate from leaking out from other positions after the first section 1 is full, so that the condensate can be locked in the second section 2, thereby improving the anti-leakage effect of the entire device.

[0049] In some embodiments, the bottom wall of the first section 1 may be lower than the bottom wall of the second section 2 or may be flush with the bottom wall of the second section 2 in the transverse direction. The first section 1 has a small edge on the side facing the second section 2, so that the first section 1 forms a liquid collecting tank with a certain liquid storage space. The guiding slope 4 may be connected to the edge at one end and connected to the second section 2 at the other end. When the liquid collecting tank is full, it can flow from the guiding slope 4 to the second section 2.

[0050] Furthermore, in some embodiments, a plurality of guide grooves 41 inclined from the second section 2 to the first section 1 are formed on the guide slope 4 .

[0051] Specifically, the transverse cross-sectional shape of the guide groove 41 can be C-shaped, V-shaped, [-shaped, etc. In the first interval 1, the condensate that is not adsorbed on the first protrusion 11 and the capillary groove 3 flows on the bottom wall of the first interval 1 and flows directly to the second interval 2 under the guidance of the guide groove 41 and the action of gravity, so that the condensate can be locked in the second interval 2, thereby improving the leakage-proof effect of the entire device.

[0052] Furthermore, in some embodiments, the guide slope 4 is further provided with at least one groove 42 , and the groove 42 extends in the axial direction, and the groove 42 has a certain liquid storage function.

[0053] In some specific embodiments, a groove 42 may be provided between the two guide grooves 41 of the guide slope 4, so that when a very small amount of condensate does not flow from the guide groove 41 to the second interval 2 but flows from the guide slope 4 between the two guide grooves 41, the part of the condensate can flow to the second interval 2 or be stored in the groove 42.

[0054] Furthermore, an atomizer includes an oil cup and a base, wherein the base is fixedly assembled on the bottom of the oil cup, and an end of the oil cup facing the base has an atomization cavity, and the atomization cavity communicates with the first section 1 and the second section 2.

[0055] In some specific embodiments, the atomizer includes an oil cup and a base, and the condensate generated from the atomization chamber can flow to the first interval 1 and the second interval 2, and be collected and locked in the first interval 1 and the second interval 2, with a good liquid storage effect, and no oil guide cotton is required, and the cost is low.

[0056] Further, in some embodiments, along the axial direction, the orthographic projection of the atomization chamber on the base at least partially covers the first interval 1 .

[0057] Specifically, in the axial direction, the central axis of the first section 1 is aligned with or staggered with the central axis of the atomizing chamber. The orthographic projection of the atomizing chamber on the base partially or completely covers the first section 1, so the condensate generated from the atomizing chamber can first flow to the first section 1, part of the condensate is adsorbed by the first convex column 11, and part of the condensate flows to the second section 2 through the guide slope 4, and the condensate is locked in the second section 2.

[0058] Furthermore, an electronic atomization device includes a battery rod assembly and an atomizer, and the battery rod assembly is connected to the atomizer through a connecting wire. Therefore, the groove 42 can also be used as a puncture groove, so that the connecting wire can pass through conveniently, and then the glue is filled and sealed.

[0059] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0060] The above is a description of the technical solution provided by the utility model. For technicians in this field, according to the ideas of the embodiments of the utility model, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the utility model.
