Description

Atomization components and atomization devices Technical Field

[0001] The utility model relates to the technical field of heat-not-burn smoking articles, and in particular to an atomization component and an atomization device. Background Art

[0002] An electronic atomizer is an electronic product that imitates cigarettes and can produce smoke like ordinary cigarette products, which can be inhaled by users.

[0003] In traditional electronic atomizers, the atomizer assembly's atomizer bracket is covered with a layer of outer cotton. This outer cotton is used to maintain pressure balance inside and outside the oil reservoir. Because the inner cotton fits tightly against the inner surface of the atomizer bracket, continuous use of the atomizer depletes the oil inside the reservoir, preventing outside air from entering. This causes the internal pressure to fall below atmospheric pressure. This requires the outer cotton to connect the oil reservoir to the outside world, preventing a pressure differential between the inside and outside of the reservoir that could prevent the oil from flowing into the inner cotton, leading to abnormalities such as sticking.

[0004] Current electronic atomization devices are gradually becoming smaller and smaller. The provision of outer cotton in the atomization component undoubtedly increases the volume of the atomization component, which is not conducive to the miniaturization of the electronic atomization device. However, if the outer cotton is not provided, it will make it difficult to balance the air pressure inside and outside the oil tank. Utility Model Content

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0035] 1 and 2 , an embodiment of the present application provides an atomization device 1 , which includes a housing 20 , an atomization assembly 10 , an upper sealing member 30 , and a lower sealing member 40 .

[0036] The atomizer assembly 10, the upper seal 30, and the lower seal 40 can all be disposed within the housing 20. The housing 20 can be used to protect the atomizer assembly 10 and ensure the normal operation of the atomizer assembly 10. In this embodiment, a nozzle 210 can be disposed at one end of the housing 20. The nozzle 210 communicates with the interior of the housing 20 and with the atomizer assembly 10. The aerosol generated by the atomizer assembly 10 heating the aerosol-generating substrate can be inhaled by the user through the nozzle 210.

[0037] Specifically, in this embodiment, the shell 20 can be roughly bullet-shaped, that is, the diameter gradually increases from one end of the shell 20 where the suction nozzle 210 is provided to the other end of the shell 20, so that it can better fit the user's mouth and facilitate the user to suck.

[0038] Furthermore, the housing 20 may include an upper housing 210 and a lower housing 220. The upper housing 210 may cover the lower housing 220. In some embodiments, the upper housing 210 may be interference-connected with the lower housing 220 to seal the gap between the upper housing 210 and the lower housing 220. In other embodiments, a sealing ring 50 may be provided between the upper housing 210 and the lower housing 220 to also seal the gap between the upper housing 210 and the lower housing 220.

[0039] The upper seal 30 can be disposed at an end near the nozzle 210 to seal the gap between the nozzle 210 and the atomizer assembly 10. The lower seal 40 can be disposed at an end away from the nozzle 210 to seal the gap between the atomizer assembly 10 and the end of the housing 20 away from the nozzle 210. In this embodiment, both the upper seal 30 and the lower seal 40 can be made of a flexible material such as rubber or resin.

[0040] In this embodiment, the housing 20, the atomizing housing 110, the upper seal 30 and the lower seal 40 form an oil tank 60. Specifically, the outer surface of the atomizing housing 110, the outer surface of the housing 20, the upper seal 30 and the lower seal 40 form an oil tank 60. The oil tank 60 can be connected to the atomizing component 10 and used to accommodate an aerosol generating matrix so that the atomizing component 10 can heat the aerosol generating matrix disposed in the oil tank 60.

[0041] Please refer to FIG. 3 to FIG. 5 at the same time. The atomizing assembly 10 is used to heat the aerosol-generating substrate. In this embodiment, the atomizing assembly 10 may include: an atomizing housing 110 , oil-conducting cotton 120 , and a heating element 130 .

[0042] The interior of the atomizing housing 110 forms a receiving chamber 111, and the atomizing housing 110 is provided with an oil inlet 112. In this embodiment, the atomizing housing 110 can be cylindrical or square, without limitation. The atomizing housing 110 can be used to protect internal components, such as the oil-conducting cotton 120, the heating element 130, etc. It is understandable that the atomizing housing 110 can be made of materials such as plastic and ceramic, without limitation.

[0043] The atomizing housing 110 is also provided with an oil inlet hole 112, which can be connected to the oil tank 60 and is used to guide the aerosol generating matrix in the oil tank 60 to the oil-conducting cotton 120, that is, the aerosol generating matrix can enter the oil-conducting cotton 120 from the oil tank 60 through the oil inlet hole 112.

[0044] Referring to FIG. 6 , it should be noted that the present embodiment does not limit the structure of the oil inlet hole 112. For example, the oil inlet hole 112 may be a circular hole as shown in FIG. 6 , or a waist-shaped hole as shown in FIG. 3 . Furthermore, multiple oil inlet holes 112 may be provided, and the multiple oil inlet holes 112 may be evenly arranged at the same height of the atomizing housing 110 , thereby ensuring more uniform adhesion of the aerosol-generating substrate to the oil-conducting cotton 120.

[0045] Specifically, referring to FIG7 , when the oil inlet hole 112 is a waist-shaped hole, the axial direction of the oil inlet hole 112 is tilted relative to the axial direction of the atomizing housing 110, as shown by the dotted line in FIG7 . This allows for more uniform transverse and longitudinal conduction of the aerosol-generating matrix within the oil-conducting cotton 120 , thereby improving the atomization effect.

[0046] Please refer to Figure 4 again. The oil-conducting cotton 120 is arranged in the accommodating cavity 111 and covers the oil inlet hole 112. The oil-conducting cotton 120 surrounds the heating cavity 121. In this embodiment, in order to enable the oil-conducting cotton 120 to more fully absorb the aerosol-generating matrix, the shape of the oil-conducting cotton 120 can be set to match the shape of the atomizing shell 110. For example, when the atomizing shell 110 is cylindrical, the oil-conducting cotton 120 can also be set to be cylindrical. When the atomizing shell 110 is square cylindrical, the oil-conducting cotton 120 can also be set to be square cylindrical.

[0047] In this embodiment, the oil-conducting cotton 120 can be made of natural or synthetic fiber materials with good oil absorption and high temperature resistance, such as organic cotton, non-woven fabrics, ceramic fibers, etc., so as to better absorb and store the aerosol generating matrix, ensuring that the aerosol generating matrix can be smoothly heated and atomized by the heating element 130.

[0048] Please refer to Figures 2 and 8 at the same time. An air flow gap 123 is formed between the atomizer housing 110 and the oil-conducting cotton 120. The air flow gap 123 can connect the oil tank 60 with the outside world to balance the air pressure inside and outside the oil tank 60, thereby preventing the aerosol generating matrix in the oil tank 60 from being consumed, resulting in a decrease in the pressure in the oil tank 60, and further preventing the aerosol generating matrix from being unable to flow into the oil-conducting cotton 120. The heating element 130 works normally to heat the oil-conducting cotton 120 without the aerosol generating matrix, resulting in the oil-conducting cotton 120 being burned and damaged.

[0049] It should be noted that the embodiment of the present application does not limit the size of the airflow gap 123. It is understandable that the airflow gap 123 should not be too large or too small. If the airflow gap 123 is too large, it may cause the aerosol to leak from the airflow gap 123. If the airflow gap 123 is too small, it may cause the air pressure in the oil tank 60 to be difficult to balance or the balancing speed is slow, which is not conducive to the heating and atomization of the aerosol generation matrix.

[0050] Referring again to Figure 4 , the heating element 130 can be disposed within the heating chamber 121 to heat the oil-conducting cotton 120, thereby heating the aerosol-generating matrix attached to the oil-conducting cotton 120. In this embodiment, the heating element 130 can employ resistive heating and include a heating mesh 131 and pins 132. Pins 132 are connected to the heating mesh 131. Two pins 132 may be provided, one for connecting to the positive electrode and the other to the negative electrode. It is understood that in some embodiments, the heating mesh 131 can be replaced by a heating wire, a heating sheet, or the like.

[0051] The atomizer assembly 10 and the atomizer device 1 provided in the embodiment of the present application, by setting an atomizer shell 110 in the atomizer assembly 10, and setting the oil-conducting cotton 120 in the accommodating cavity 111 of the atomizer shell 110, and setting the heating element 130 in the heating cavity 121 of the oil-conducting cotton 120, form an airflow gap 123 between the atomizer shell 110 and the oil-conducting cotton 120, and the airflow gap 123 can be used to balance the air pressure inside and outside the atomizer assembly 10. When the atomizer assembly 10 is applied to the atomizer device 1, the airflow gap 123 can connect the oil tank 60 with the outside world to balance the air pressure inside and outside the oil tank 60. The atomizer assembly 10 and the atomizer device 1 provided in the embodiment of the present application reduce the use of components, reduce the volume of the atomizer assembly 10 and the atomizer device 1, and can balance the air pressure inside and outside the oil tank 60, thereby solving the problem in the prior art that the electronic atomizer device 1 is difficult to achieve both small volume and balanced air pressure in the oil tank 60.

[0052] Please refer to Figure 3 again. In this embodiment, the inner wall of the atomizer housing 110 can be provided with a convex rib 113, and the oil-conducting cotton 120 abuts against the convex rib 113, and an airflow gap 123 is formed on both sides of the convex rib 113. It can be understood that due to the provision of the convex rib 113, when the oil-conducting cotton 120 contacts the inner wall of the atomizer housing 110, it actually only contacts the convex rib 113. The oil-conducting cotton 120 does not contact other areas of the inner wall of the atomizer housing 110 except the convex rib 113. In this way, a gap is formed between the oil-conducting cotton 120 and other areas of the inner wall of the atomizer housing 110 except the convex rib 113. This gap is the airflow gap 123. The convex rib 113 can also be used to position the oil-conducting cotton 120 to prevent the oil-conducting cotton 120 from moving within the atomizer housing 20 and affecting the atomization efficiency. It should be noted that the embodiment of the present application does not limit the shape of the convex rib 113. For example, the convex rib 113 can be a round bar-shaped convex rib 113 or a square bar-shaped convex rib 113.

[0053] It should be noted that, in some other embodiments, the ribs 113 may also be formed on the outer surface of the oil-conducting cotton 120 , so that an airflow gap 123 can be formed between the oil-conducting cotton 120 and the atomizing housing 110 .

[0054] Referring to FIG8 , in one embodiment, the atomizing housing 110 may be recessed radially inward to form a rib 113. This reduces the weight of the atomizing housing 110, saves material for the atomizing housing 110, and reduces the cost of the atomizing device 1. Furthermore, the rib 113 may be positioned at the oil inlet 112, which brings the airflow gap 123 closer to the oil inlet 112, facilitating gas exchange between the inside and outside of the oil tank 60 and balancing the pressure inside and outside the oil tank 60.

[0055] In another embodiment, the rib 113 can be provided separately, that is, the rib 113 can be detachably connected to the inner wall of the atomizer housing 110. This allows the rib 113 to be more flexibly provided on the inner wall of the atomizer housing 110 to accommodate oil-conducting cotton 120 of various shapes.

[0056] In some embodiments, multiple ribs 113 can be provided, and the multiple ribs 113 can be evenly spaced and arranged on the inner wall of the atomizing shell 110. Furthermore, the multiple ribs 113 can also be arranged at the same height on the inner wall of the atomizing shell 110 to improve the positioning effect of the ribs 113 on the oil-conducting cotton 120.

[0057] Please refer to FIG. 9 . Specifically, the rib 113 may extend along the axis of the atomizer housing 110 . This may increase the contact area between the rib 113 and the oil-conducting cotton 120 , thereby facilitating the fixing of the rib 113 to the oil-conducting cotton 120 .

[0058] Referring to Figure 10 , it can be understood that the end of the rib 113 at least protrudes beyond the end surface of the oil-conducting cotton 120. This prevents the oil-conducting cotton 120 from absorbing the aerosol-generating matrix and blocking the airflow gap 123. Specifically, because the airflow gap 123 is formed in an area other than the rib 113 between the oil-conducting cotton 120 and the inner wall of the atomizer housing 110, this area may be filled by the oil-conducting cotton 120 after absorbing the aerosol-generating matrix, resulting in the airflow gap 123 being closed. Furthermore, in this embodiment, for ease of processing, the rib 113 can extend through the entire axial direction of the atomizer housing 110.

[0059] In some other embodiments, the ribs 113 may not be provided. In this case, the outer surface of the oil-conducting cotton 120 may be set to a rough surface. Since the outer surface of the oil-conducting cotton 120 is a rough surface, the outer surface of the oil-conducting cotton 120 cannot be completely fitted with the inner wall of the atomizing shell 110. Therefore, an airflow gap 123 is formed between the outer surface of the oil-conducting cotton 120 (i.e., the rough surface) and the inner wall of the atomizing shell 110. That is to say, the oil-conducting cotton 120 abuts against the atomizing shell 110, but there is no tight connection or interference connection, so that there is an airflow gap 123 between the oil-conducting cotton 120 and the inner wall of the atomizing shell 110 through which airflow can pass. It should be noted that in some other embodiments, the inner surface of the atomizing shell 110 may also be set to a rough surface, or the inner surface of the atomizing shell 110 and the outer surface of the oil-conducting cotton 120 may both be set to rough surfaces. In this way, the above-mentioned effect can also be achieved. This can simplify the structure of the atomizing housing 110 , making production and processing more convenient. At the same time, the structure of the atomizing housing 110 can also play a role in forming the airflow gap 123 .

[0060] It should be noted that, in some other embodiments, the shape of the oil-guiding cotton 120 may not match the shape of the atomizing shell 110. For example, the shape of the oil-guiding cotton 120 may be cylindrical, and the shape of the atomizing shell 110 may be square cylindrical. The cross-sectional diameter of the oil-guiding cotton 120 may be the same as or slightly larger than the cross-sectional diameter of the atomizing shell 110. In this way, an air flow gap 123 is naturally formed between the atomizing shell 110 and the oil-guiding cotton 120 without setting the rib 113 on the atomizing shell 110. This can reduce the difficulty of mold production of the atomizing shell 110 and facilitate production and processing.

[0061] The atomizer assembly 10 and the atomizer device 1 provided in the embodiment of the present application, by setting an atomizer shell 110 in the atomizer assembly 10, and setting the oil-conducting cotton 120 in the accommodating cavity 111 of the atomizer shell 110, and setting the heating element 130 in the heating cavity 121 of the oil-conducting cotton 120, form an airflow gap 123 between the atomizer shell 110 and the oil-conducting cotton 120, and the airflow gap 123 can be used to balance the air pressure inside and outside the atomizer assembly 10. When the atomizer assembly 10 is applied to the atomizer device 1, the airflow gap 123 can connect the oil tank 60 with the outside world to balance the air pressure inside and outside the oil tank 60. The atomizer assembly 10 and the atomizer device 1 provided in the embodiment of the present application reduce the use of components, reduce the volume of the atomizer assembly 10 and the atomizer device 1, and can balance the air pressure inside and outside the oil tank 60, thereby solving the problem in the prior art that the electronic atomizer device 1 is difficult to achieve both small volume and balanced air pressure in the oil tank 60.
