Description

Electronic atomizer assembly and electronic cigarette

Technical Field

The present disclosure relates to an electronic atomizer assembly and an electronic cigarette.

Background

The electronic atomizer assembly is a core component of an electronic cigarette, and generates smoke by heating liquid (also called tobacco tar), and in the conventional design of the existing electronic atomizer, a user simulates the feeling of smoking by smoking the smoke generated by the electronic cigarette.

An existing electronic atomizer assembly includes a liquid storage casing, an air duct disposed in the liquid storage casing, and an atomizer (also called a heat generating core, typically a ceramic heat generating core) disposed in the air duct (typically in the form of a central column). A liquid storage cavity is defined between the liquid storage shell and the air guide tube and is sealed by the cover component. The smoke liquid in the liquid storage cavity reaches the atomizer through a liquid inlet hole arranged on the pipe wall at the lower end of the air guide pipe. The air duct is used to form a part of an air passage for delivering the aerosol generated by the atomizer to a user through a cap assembly (or a suction nozzle).

In the conventional design of the existing electronic atomizer component, non-woven fabric and other oil absorption elements are often wrapped around the ceramic heating core to play the roles of absorbing oil, guiding oil and sealing oil, but the non-woven fabric and other oil absorption elements are wrapped around the ceramic heating core, and certain tightness is required, so that the production is very difficult; the core (the external diameter is greater than the center post internal diameter) that generates heat that will wrap up in oil absorption components such as non-woven fabrics in addition packs into the center post and also than difficult dress, and is required highly to the assembly process, and the productivity is low, and long-term operation still can lead to the assembly personnel to point injuries such as blister and scotch, seriously influences production efficiency.

Simultaneously, with the whole side of whole ceramic heating element parcel in a large scale and the mode of contact non-woven fabrics (cotton) like this, because ceramic heating element is to the continuous heating or even dry combustion of non-woven fabrics (cotton) or other imbibition components in the use, also can produce negative effects, especially in the aspect of the taste to customer experience. Furthermore, alveolar macrophages are unique in their lifespan and their important role in lung development and lung function, as well as their positive response to lung infections and inflammation. However, research data indicate that inhalation of smoke from cotton combustion inhibits the antibacterial activity of alveolar macrophages and may result in excessive TNF-alpha (tumor necrosis factor-alpha) production by alveolar macrophages.

Detailed Description

The descriptions of the upper, lower, top, bottom, etc. referred to in this disclosure with respect to the orientation are based on the description with the gas flow direction in the gas channel as the upper side, and these descriptions are used for the sake of understanding only to describe the relative positional relationship between the respective structures, and are not used to describe the absolute positional relationship of the respective structures.

Fig. 2, 3 and 4 show schematic cross-sectional structural views of electronic atomizer assemblies according to first, second and third embodiments of the present disclosure, respectively.

As can be seen in fig. 1-4, in an embodiment of the present disclosure, an electronic atomizer assembly is provided. The electronic atomizer assembly comprises a liquid storage shell 5; the air duct 4 is arranged in the liquid storage shell 5, a liquid storage cavity 7 is defined between the air duct 4 and the liquid storage shell 5, an atomization cavity 411 is formed in the air duct 4, and an atomization cavity liquid inlet hole 412 is formed in the side wall of the atomization cavity 411; the atomizer 1 is arranged in the atomizing chamber 411, the atomizer 1 comprises an atomizer body 11 made of porous material and a heating element (not shown in the figure) arranged in the atomizer body 11, and the atomizer body 11 corresponds to the position of the liquid inlet hole 412 of the atomizing chamber; and the gas channel P penetrates through the gas guide pipe 4 and the atomizer 1. At least one end face of the atomizer body 11 in the longitudinal direction of the gas passage P is provided with a deformable blocking element extending circumferentially around the gas passage P to block the smoke liquid from blocking the gas passage. At least one of the two end faces of the atomizer body 11 is provided with an axial annular flange extending around the gas passage P and located radially inside the blocking element 2.

In practical use of the electronic cigarette, an important reason for smoke liquid blockage and smoke liquid suction (smoke liquid splashing) is that smoke liquid may enter the gas channel from the gap between the side wall of the atomizer body 11 and the inner wall of the atomizing chamber through the gap between the end face of the atomizer body and the inner wall of the atomizing chamber during the suction process. The smoke liquid can also permeate into the gas channel through the inner wall of the porous ceramic to form a blockage. The present disclosure provides a deformable blocking element at the end face of the atomizer body, cutting off the path of the smoke liquid entering the gas channel via the end face gap. In addition, compared with the scheme that non-woven fabrics are wrapped around the side wall of the atomizer body or a silicon sleeve 33023is arranged, extra blocking elements are not required to be arranged around the side wall of the atomizer body, so that the volume and the wall thickness of the atomizer body (such as a ceramic core) can be increased, and the absorption and liquid storage capacity of the atomizer body is improved. Thus, the solution of the present disclosure may form a double barrier preventing smoke liquid from blocking the gas passage and smoke liquid from being sucked, greatly reducing the possibility that smoke liquid (especially heated hot oil) enters the gas passage, causing smoke liquid to block the gas passage and smoke liquid to be sucked. Moreover, because the scheme of this disclosure has improved the absorption and the stock solution ability of atomizer body, consequently can also make the atomizing process more smooth and easy, improved user's smoking from this and experienced. In addition, because the blocking element is arranged on the end face of the atomizer body, the periphery of the side wall of the atomizer body is not required to be wrapped with non-woven fabrics and the like, and therefore installation is greatly simplified. Simultaneously, the tobacco juice through the feed liquor hole is directly absorbed by porous ceramic heat-generating body, greatly reduced the tradition wrap up in cotton mode, the atomizing body contacts the cotton in a large scale and leads to burning cotton and influence taste and latent health risk. In addition, by providing an axial annular flange located radially inside the blocking element, the assemblability of the blocking element can be increased and bridging of smoke liquid into the gas passage via the cotton ring can be avoided.

In this embodiment, the blocking member 2 may be a liquid absorbing member having an absorbing function. The wicking element can be, for example, a cotton ring.

Therefore, by the support step 51 at the lower end of the reservoir housing 5 and the cap assembly 6 at the upper end of the reservoir housing 5, reliable fixation of the air-guide tube 4 can be ensured.
