Description

Technical Field

[0001] The utility model belongs to the technical field of electronic atomizers, and in particular relates to an atomization core component and an electronic atomizer. Background Art

[0002] The structural design of the air guide channel of the electronic cigarette has a crucial impact on the generation of aerosol. The air guide channel should not only ensure that the airflow from the air inlet channel acts on the atomizer core as much as possible to increase the atomization volume, but also shorten the circulation distance of the atomized gas as much as possible and reduce the contact area with the internal structural parts, thereby reducing the condensation of the atomized gas.

[0003] For example, Chinese utility model patent CN 216292995 U discloses an electronic cigarette atomization component and an electronic cigarette, in which the air guide port located on the atomization top cover and the air inlet channel located on the atomization bottom cover are located on the same axis. This makes it difficult for the gas to directly act on the atomization core during the inhalation process, thereby greatly reducing the amount of atomization. At the same time, due to the coaxial line design, the probability of condensed liquid droplets flowing back into the air inlet channel is greatly increased, which can easily cause equipment failure.

[0004] Details of one or more embodiments of the present invention are set forth in the following drawings and description to make other features, objects, and advantages of the present application more readily apparent.

[0005] The utility model provides an atomizer core assembly and an electronic atomizer. By reasonably arranging the positional relationship between the air guide port, the air guide channel, the atomizer core and the air inlet channel, the air flow is smoother, and the circulation distance of the atomized gas and the contact area with the internal structural parts can be greatly reduced, thereby reducing the occurrence of condensation and giving consumers a better inhalation experience.

[0006] The utility model discloses an atomizer core assembly, comprising an atomizer top cover and an atomizer bottom cover, and also comprises:

[0014] In some embodiments, the liquid conducting channel is in a U-shaped or V-shaped structure.

[0015] In some embodiments, it also includes:

[0016] An atomizer core mounting frame is arranged in the atomizer top cover and is provided with an atomizer core mounting groove for mounting the atomizer core; the lower end surface of the atomizer core mounting frame is flush with the atomizer core;

[0024] Compared with the prior art, the beneficial effects of the utility model are as follows: the air inlet channel is designed to be directly opposite to the atomizer core, so that the contact between the airflow and the atomizer core is more direct, so as to generate aerosol more efficiently.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described and illustrated in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments provided by the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0034] Obviously, the drawings described below are only some examples or embodiments of the utility model. For ordinary technicians in this field, the utility model can also be applied to other similar scenarios based on these drawings without creative work. In addition, it can be understood that although the efforts made in this development process may be complicated and lengthy, for ordinary technicians in this field related to the content disclosed by the utility model, some changes in design, manufacturing or production based on the technical content disclosed by the utility model are just conventional technical means, and should not be understood as the content disclosed by the utility model is insufficient.

[0035] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments without conflict.

[0036] An atomizer core assembly includes an atomizer top cover 1 and an atomizer bottom cover 2, and also includes:

[0037] An air guide channel, the upper end of which is connected to the air guide port 3 on the atomizing top cover 1, and the lower end of which extends between the atomizing top cover 1 and the atomizing bottom cover 2;

[0038] At least two atomizer cores 4 are distributed on the periphery of the lower end of the air guide channel, and the lower end surface of the atomizer core 4 is flush with the lower end surface of the air guide channel;

[0039] At least two air inlet channels 9 are provided on the atomizer bottom cover 2 . The number of atomizer cores and air inlet channels corresponds to each other, and each air inlet channel 9 is provided correspondingly to each atomizer core 4 .

[0040] Specifically, the number of atomizer cores 4 is at least two; when two atomizer cores 4 are used, they are symmetrically distributed on both sides of the lower end of the air guide channel; when more than three atomizer cores are used, they are evenly distributed at the outer periphery of the lower end of the air guide channel to ensure the uniformity of its atomization; at the same time, the number and position of the air inlet channels 9 correspond to the atomizer cores 4, so that the airflow directly acts on the corresponding heating end of the atomizer core 4 through each air inlet channel 9 to quickly form atomized gas, and under the action of negative pressure adsorption, it quickly flows to the air guide channel located in the middle and is discharged from the air guide port 3. The atomized gas is in a planar structure on the flow end surface of its upper end to ensure the smoothness of the atomized gas flow while reducing the contact area with its internal structure, and because the above-mentioned structure is combined, the air guide port 3 and the air inlet channel 9 must be arranged in a staggered structure, which also avoids the risk that the condensate generated at the air guide port 3 will drip into the air inlet channel 9 along the air guide channel in the later stage, thereby improving the safety and reliability of the device.

[0041] The above solution is further fully explained by combining Example 1 and Example 2.

[0042] In Example 1, that is, Figure 1 , 2 As shown in FIG. 3 , the atomizer core 4 is arranged in a longitudinal horizontal direction, and this method is suitable for a product structure with a larger internal space.

[0043] This product structure has a relatively large demand for aerosol volume, so there are certain design requirements for the liquid guide port and the air guide channel, including:

[0044] The liquid guide channel has an upper end connected to a liquid guide port 6 on the atomizer top cover 1 , and a lower end connected to an atomizer core mounting groove 5 for mounting an atomizer core 4 ; the number of the liquid guide port is at least one.

[0045] In some embodiments, each atomizer core may correspond to a liquid guide channel, and each corresponding liquid guide channel may correspond to two liquid guide ports above the liquid guide channel, and the two liquid guide ports may adopt a symmetrical structure design (such as Figure 1 and Figure 3 As shown in the figure, the liquid guiding and feeding effect is improved. Specifically, the whole structure can be U-shaped or V-shaped. Among them, the U-shaped structure is smoother and more stable.

[0046] At the same time, since the amount of aerosol generated is relatively large, the air guide channel is further designed to be a structure with a reduced diameter from bottom to top, and a condensate guide plate 14 is provided inside it. The reduced diameter structure design can gather and collect the aerosol while ensuring the suction feeling, and combined with high power, the aerosol is fuller, and since the aerosol is fuller, a certain degree of condensation will inevitably occur there, and thus a pair of symmetrically arranged condensate guide plates 14 are provided in this embodiment, and the condensate guide plates 14 are also designed with a reduced diameter structure from bottom to top to break the condensate on the airway and prevent the condensate from accumulating there.

[0047] In Example 2, that is, Figure 4 , 5 As shown in FIG. 6 , the atomizer core 4 is arranged in a horizontal direction. This method is suitable for product structures with thinner internal spaces to meet the market demand for thinner products.

[0048] In this structure, since the product adopts a lightweight design, the demand for the amount of aerosol is lower than that of Example 1, so the liquid guide port 6 at the upper end of the liquid guide channel can be designed as one, and of course it can be set to multiple according to needs. At the same time, since the amount of aerosol is relatively small, a relatively easy-to-process through-path structure design can be adopted in its air guide channel, and there is no need to add a corresponding condensate guide plate 14. It should be noted that although in Example 2, a through-path structure design is adopted, and there is no need to add a condensate guide plate 14, according to actual needs, the implementation method in Example 1 can also be used in the same way.

[0049] In some embodiments, it also includes:

[0050] The atomizer core mounting frame is arranged in the atomizer top cover 1 and is provided with an atomizer core mounting groove 5 for mounting the atomizer core 4; the lower end surface of the atomizer core mounting frame is flush with the atomizer core 4;

[0051] The top cover liquid absorbent cotton installation groove 11 is used to install the top cover liquid absorbent cotton and is arranged between the atomizer core installation frame and the atomizer top cover 1, and the lower end of the top cover liquid absorbent cotton at least extends to the lower end surface of the atomizer core 4.

[0052] A bottom cover mounting seat is protrudingly arranged at the bottom end of the atomizer bottom cover, and the number of the bottom cover mounting seats corresponds to the number of the air inlet channels, so as to be used for mounting each air inlet channel;

[0053] The bottom cover liquid absorbent cotton installation groove 10 is used to install the bottom cover liquid absorbent cotton and is arranged between the bottom cover installation seat 7 and the atomizing bottom cover, and the upper end of the bottom cover liquid absorbent cotton is in contact with the top cover liquid absorbent cotton.

[0054] The advantage of adopting the above design is that the overall space area inside can be further reduced by the top cover absorbent cotton and the bottom cover absorbent cotton to reduce the contact area with the atomized gas, thereby reducing the probability of condensation inside. At the same time, the top cover absorbent cotton and the bottom cover absorbent cotton abut against each other, which also relatively improves the sealing inside. The restriction of the airflow through the top cover absorbent cotton and the bottom cover absorbent cotton acts more directly on the atomizing core 4 to generate atomized gas and effectively guide it out.

[0055] In some embodiments, since an atomizing core 4 of a long strip structure is used, in order to improve the atomization effect, in combination with the setting mode of the air inlet channel 9, conductive nails 8 are symmetrically arranged on both sides of the air inlet channel 9. The air inlet channel 9 is composed of at least one air inlet hole, and its specific structural form can be a porous whole-row structural distribution.

[0056] An electronic atomizer comprises: an atomizer core assembly as described in any one of the above embodiments.

[0057] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
