Abstract

This utility model provides an atomizer, which includes an oil cup, a liquid guiding mechanism, and an atomizing core. The top of the oil cup has an outlet connected to the atmosphere, and the bottom has a fixed base. The liquid guiding mechanism includes a support, a first oil-retaining cotton, a second oil-retaining cotton, and a fixed cover with a lower oil hole. The first oil-retaining cotton is fixed to the support and sleeved on the outside of the fixed cover, and the second oil-retaining cotton is fixed on the inside of the fixed cover. The first and second oil-retaining cottons are respectively arranged corresponding to the lower oil hole, and a ventilation channel connecting to the outlet is formed inside the second oil-retaining cotton. The support is fixed to the top of the fixed base and abuts against the inner wall of the oil cup.

By implementing the solution of this application, the oil-retaining cotton is placed on the outside of the lower oil hole of the fixed cover, which can effectively reduce the oil pressure at the lower oil hole, thereby effectively reducing the risk of oil leakage caused by excessive oil saturation of the oil-retaining cotton inside the fixed cover.

Description

Technical Field

[0001] This utility model belongs to the field of atomization technology, and in particular relates to an atomizer. Background Technology

[0002] An atomizer is a device that atomizes e-liquid (e-liquid) into an aerosol. An atomizer generally includes a shell, a reservoir, a liquid guiding structure, and an atomizer coil. The reservoir is formed inside the shell, and the liquid guiding structure directs the e-liquid from the reservoir to the atomizer coil. When powered on, the atomizer coil heats the e-liquid to produce an aerosol. In related technologies, a common liquid guiding structure is an air duct combined with non-woven fabric. However, for large-capacity atomizers, the high pressure of the e-liquid inside the shell and the limited oil-locking capacity of the non-woven fabric make the atomizer prone to leakage. Utility Model Content

[0003] The technical objective of this utility model is to provide an atomizer that solves the problem of poor oil-locking effect of the liquid guiding structure in related technologies, which leads to easy oil leakage in the atomizer.

[0004] To solve the above-mentioned technical problems, this utility model provides an atomizer, including: an oil cup, a liquid guiding mechanism, and an atomizing core; the top of the oil cup is provided with an air outlet communicating with the atmosphere, and the bottom is provided with a fixed base; the liquid guiding mechanism includes a bracket, a first oil storage cotton, a second oil storage cotton, and a fixed cover with a lower oil hole, the first oil storage cotton is fixed to the bracket and sleeved on the outside of the fixed cover, the second oil storage cotton is fixed to the inside of the fixed cover, and the first oil storage cotton and the second oil storage cotton are respectively arranged corresponding to the lower oil hole, and a ventilation channel communicating with the air outlet is also formed in the second oil storage cotton; the bracket is fixed to the top of the fixed base and abuts against the inner wall of the oil cup, and the oil cup, the fixed cover, the first oil storage cotton, and the bracket together form a liquid storage cavity; the atomizing core is fixed in the ventilation channel.

[0005] Furthermore, the extension length of the first oil-absorbing cotton in the axial direction is less than the extension length of the second oil-absorbing cotton.

[0006] Furthermore, the density of the first oil-bearing cotton is less than that of the second oil-bearing cotton.

[0007] Furthermore, the density of the first type of oil-bearing cotton is 0.06–0.08 g / cm³. 3 And / or, the density of the second oil storage cotton is 0.09–0.12 g / cm³. 3 .

[0008] Furthermore, the fiber direction of the first oil-absorbing cotton is parallel to that of the second oil-absorbing cotton.

[0009] Furthermore, the fiber direction of the first oil-absorbing cotton is perpendicular to the fiber direction of the second oil-absorbing cotton.

[0010] Furthermore, a support is provided between the outer side of the atomizing core and the second oil reservoir cotton, and the support has an oil passage connecting the second oil reservoir cotton to the atomizing core.

[0011] Furthermore, the atomizing core includes an oil-guiding cotton abutting against the inner wall of the support and a heating element abutting against the side of the oil-guiding cotton away from the support. An atomizing chamber communicating with the air passage is also formed inside the heating element.

[0012] Furthermore, the side of the bracket away from the fixed base is connected to a plurality of mutually spaced limiting parts, and the end of each limiting part away from the bracket is also connected to an abutting part extending toward the fixed cover. Each limiting part abuts against the outer periphery of the first oil-storing cotton, and each abutting part abuts against the top of the first oil-storing cotton.

[0013] Furthermore, the atomizer also includes a battery assembly, which is electrically connected to the atomizer.

[0014] Compared with the prior art, the beneficial effects of this atomizer are as follows: a first oil storage cotton and a second oil storage cotton are respectively set at the inlet and outlet of the lower oil hole. The e-liquid in the liquid storage chamber must pass through the first oil storage cotton before reaching the lower oil hole. The presence of the first oil storage cotton can reduce the oil pressure at the lower oil hole, thereby reducing the e-liquid saturation in the second oil storage cotton and achieving the purpose of preventing oil leakage.

[0027] Example:

[0028] like Figure 1-4As shown, in this embodiment, the atomizer includes: an oil cup 1, a liquid guiding mechanism, and an atomizing core 7; the top of the oil cup 1 is provided with an air outlet 11 communicating with the atmosphere, and the bottom is provided with a fixing base 2; the liquid guiding mechanism includes a bracket 3, a first oil storage cotton 4, a second oil storage cotton 5, and a fixing cover 6 with a lower oil hole 61. The first oil storage cotton 4 is fixed to the bracket 3 and sleeved on the outside of the fixing cover 6, and the second oil storage cotton 5 is fixed to the inside of the fixing cover 6. The first oil storage cotton 4 and the second oil storage cotton 5 are respectively provided corresponding to the lower oil hole 61. A ventilation channel 51 communicating with the air outlet 11 is also formed in the second oil storage cotton 5; the bracket 3 is fixed to the top of the fixing base 2 and abuts against the inner wall of the oil cup 1. The oil cup 1, the fixing cover 6, the first oil storage cotton 4, and the bracket 3 together form a liquid storage cavity 12; the atomizing core 7 is fixed in the ventilation channel 51.

[0029] Specifically, the first oil-retaining cotton 4 and the second oil-retaining cotton 5 can both be integral cotton. The first oil-retaining cotton 4 and the second oil-retaining cotton 5 are respectively set at the inlet and outlet of the lower oil hole 61. The e-liquid in the liquid storage chamber 12 must pass through the first oil-retaining cotton 4 before reaching the lower oil hole 61. The presence of the first oil-retaining cotton 4 can reduce the oil pressure at the lower oil hole 61, thereby reducing the saturation of e-liquid in the second oil-retaining cotton 5 and achieving the purpose of preventing oil leakage.

[0030] In this embodiment, the axial extension length of the first oil-retaining cotton 4 is less than the axial extension length of the second oil-retaining cotton 5. During the operation of the atomizing chamber 84, e-liquid can penetrate downward from the top of the first oil-retaining cotton 4 and / or penetrate inward from the outside of the first oil-retaining cotton 4, then reach the lower oil hole 61 and penetrate into the first oil-retaining cotton 4 and the atomizing core 7. Since the axial extension length of the first oil-retaining cotton 4 is relatively small (i.e., the first oil-retaining cotton 4 is relatively short), it slows down the speed at which the e-liquid reaches the lower oil hole 61 to a certain extent, while ensuring that the liquid storage chamber 12 can drain oil normally. The axial extension length of the second oil-retaining cotton 5 is relatively large (i.e., the second oil-retaining cotton 5 is relatively tall), giving it a larger volume and achieving a good oil-locking effect.

[0031] In this embodiment, the density of the first oil-retaining cotton 4 is less than that of the second oil-retaining cotton 5. This density difference between the first oil-retaining cotton 4 and the second oil-retaining cotton 5 ensures that the liquid storage chamber 12 can dispense oil normally, while further improving the leak-proof effect of the atomizer.

[0032] Furthermore, in this embodiment, the density of the first oil-absorbing cotton 4 can be 0.06–0.08 g / cm³. 3 Preferably, the density of the first oil-absorbing cotton 4 can be 0.07 g / cm³. 3 Of course, in some other specific embodiments, the density of the first oil-absorbing cotton 4 can also be 0.060 g / cm³. 3 0.065g / cm 30.068g / cm 3 0.072g / cm 3 0.075g / cm 3 0.078g / cm 3 0.080g / cm 3 Etc., are not limited here. In this embodiment, the density of the second oil-absorbing cotton 5 can be 0.09–0.12 g / cm³. 3 Preferably, the density of the second oil-absorbing cotton 5 can be 0.1 g / cm³. 3 Of course, in some other specific embodiments, the density of the second oil-absorbing cotton 5 can also be 0.090 g / cm³. 3 0.095g / cm 3 0.098g / cm 3 0.105g / cm 3 0.110 g / cm 3 0.112 g / cm 3 0.115g / cm 3 0.120g / cm 3 etc., without restriction.

[0033] In some embodiments, the fiber direction of the first oil-absorbing cotton 4 and the fiber direction of the second oil-absorbing cotton 5 are parallel. For example, the limiting direction of the first oil-absorbing cotton 4 and the limiting direction of the second oil-absorbing cotton 5 can both be parallel to the axial direction of the fixing cover 6.

[0034] In other embodiments, the fiber direction of the first oil-absorbing cotton 4 is perpendicular to the fiber direction of the second oil-absorbing cotton 5. For example, the fiber direction of the first oil-absorbing cotton 4 can be parallel to the axial direction of the fixing cover 6, and the fiber direction of the second oil-absorbing cotton 5 can be parallel to the radial direction of the fixing cover 6; of course, the fiber direction of the first oil-absorbing cotton 4 can also be parallel to the radial direction of the fixing cover 6, and the fiber direction of the second oil-absorbing cotton 5 can be parallel to the axial direction of the fixing cover 6, and no limitation is made here.

[0035] In this embodiment, a support member 83 is also provided on the outer side of the atomizing core 7 and between the second oil reservoir 5. The support member 83 has an oil passage opening that connects the second oil reservoir 5 to the atomizing core 7. The second oil reservoir 5 is clamped by the support tube and the fixing cover 6, which helps to improve the assembly stability of the second oil reservoir 5. Moreover, the oil passage enables the transmission of e-liquid between the second oil reservoir 5 and the atomizing core 7, which helps to reasonably control the amount of e-liquid and improve the working stability of the atomizing core 7.

[0036] Furthermore, in this embodiment, the atomizing core 7 includes an oil-guiding cotton 81 abutting against the inner wall of the support member 83 and a heating element 82 abutting against the side of the oil-guiding cotton 81 facing away from the support member 83. An atomizing chamber 84 communicating with the air passage 51 is also formed inside the heating element 82. Specifically, the bottom side of the heating element 82 can be connected to the battery assembly 9 via a conductive structure 821. During atomizer operation, the atomized liquid stored in the liquid storage chamber 12 can reach the lower oil hole 61 along the first oil storage cotton 4. After passing through the lower oil hole 61, the atomized liquid can sequentially pass through the second oil storage cotton 5, the oil outlet, and the oil-guiding cotton 81 to reach the heating element 82. When the heating element 82 is energized, it can heat and atomize the atomized liquid to form an aerosol. The generated aerosol mixes with the atmosphere in the atomizing chamber 84 and can then reach the outside of the atomizing chamber 84 along the air passage 51 and the air outlet 11 for the user to inhale.

[0037] In this embodiment, the side of the bracket 3 facing away from the fixed base 2 is connected to a plurality of mutually spaced limiting parts 31. Each limiting part 31, at its end away from the bracket 3, is also connected to an abutment part 32 extending toward the fixed cover 6. Each limiting part 31 abuts against the outer periphery of the first oil-collecting cotton 4, and each abutment part 32 abuts against the top of the first oil-collecting cotton 4. A liquid inlet gap is formed between adjacent limiting parts 31, allowing at least a portion of the liquid in the liquid storage chamber 12 to enter the first oil-collecting cotton 4 through the liquid inlet gap. The setting of the limiting parts 31 and the abutment parts 32 ensures good assembly stability of the first oil-collecting cotton 4, and the spaced-apart limiting parts 31 and abutment parts 32 provide a sufficiently large e-liquid contact surface for the first oil-collecting cotton 4, which is beneficial for oil discharge. In this embodiment, multiple oil discharge holes 61 can be provided, and these holes 61 can be evenly distributed in the section of the fixed cover 6 near the fixed base 2.

[0038] In this embodiment, the bracket 3 is also provided with a clearance opening for the conductive structure 821 to pass through, and the fixed base 2 is also provided with an air intake channel connecting to the outside. The clearance opening not only facilitates the connection between the conductive structure 821 of the heating element 82 and the battery assembly 9, but also provides a flow channel for the atmosphere entering the fixed base 2 along the air intake channel to reach the ventilation channel 51, ensuring that a stable airflow exchange can be achieved between the outside and the atomizer.

[0039] Furthermore, in this embodiment, an installation groove can be opened on the side of the bracket 3 away from the fixed base 2, which is directly opposite to the second oil storage cotton 5, so that the opening can be connected to the bottom of the installation groove. Oil-absorbing cotton can be set in the installation groove to absorb the e-liquid that may leak out from the second oil storage cotton 5, which is beneficial to further improve the leak-proof effect of the atomizer.

[0040] In this embodiment, an annular limiting edge 33 is also connected to the side of the bracket 3 away from the liquid storage cavity 12. The top side of the fixing seat 2 has a limiting groove corresponding to the annular limiting edge 33, and the annular limiting edge 33 is embedded in the limiting groove. A sealing ring 34 is provided on the outer periphery of the bracket 3, and the sealing ring 34 directly abuts against the inner wall of the oil cup 1 to achieve interference fit. This assembly not only ensures the assembly stability of the bracket 3, but also helps to further improve the leak-proof effect of the atomizer, that is, it can effectively prevent e-liquid from leaking out from the connection gap between the bracket 3 and the oil cup 1.

[0041] In this embodiment, the atomizer also includes a battery assembly 9, which is electrically connected to the atomizing core 7. The battery assembly 9 can supply power to the heating element 82 of the atomizing core 7 through a conductive structure 821 (such as an electrode assembly).

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
