This application claims priority to Chinese Patent Application entitled “Atomizer and electronic cigarette” with application number of 201921237758.1, submitted to China National Intellectual Property Administration on Jul. 30, 2019, the entire contents of which are incorporated herein by reference.
The present disclosure relates to the field of electronic cigarettes, and in particular to an atomizer and an electronic cigarette.
Tobacco products (e.g., cigarettes, cigars, etc.) are burning tobaccos to produce tobacco smoke during use. People attempt to make products that release compounds without burning so as to replace the tobacco products burning tobaccos.
An example of this type of product is a heating device, which heats rather than burns a material to release compounds, for example, the material may be a tobacco product or other non-tobacco products which may contain or not contain nicotine. As an example, there is an aerosol supplying product, for example, the so called electronic cigarette device. These devices generally contain an e-liquid, which is heated and atomized to generate an inhalable vapor or aerosol. The e-liquid may contain nicotine and/or aromatics and/or aerosol generating substances (for example, glycerol).
Known electronic cigarette devices generally include a porous ceramic element having a large number of micropores, which is configured for absorbing and transferring the e-liquid; further, a heating element is arranged on one surface of the porous ceramic element to heat and atomize the absorbed e-liquid. The micropores inside the porous element on one hand act as a channel through which the e-liquid soaks and flows onto the atomizing surface, and on the other hand act as an air exchange channel through which air is supplied to the liquid storage chamber from the outside to maintain the air pressure inside the liquid storage chamber when the e-liquid inside the liquid storage chamber is consumed, such that bubbles are generated inside the porous ceramic element when the e-liquid is consumed through heating and atomization, and then the bubbles emerge from the e-liquid absorbing surface to enter the liquid storage chamber. In order for the porous ceramic element to be installed and fixed inside the atomizer, as an existing technology, the porous ceramic element generally is assembled inside an accommodation support, meanwhile an e-liquid guiding channel is defined on the accommodation support to transfer the e-liquid to the e-liquid absorbing surface of the porous ceramic element; however, lots of bubbles generated during atomization will gather at the e-liquid guiding channel communicated with the e-liquid absorbing surface after emerging from the e-liquid absorbing surface, thereby affecting the absorption of e-liquid of the e-liquid absorbing surface.
In order to solve the problem in existing technologies that the atomizer does not supply an e-liquid smoothly, the embodiment of the present disclosure provides an atomizer that can supply an e-liquid smoothly.
Based on the above aim, the atomizer of the present disclosure includes an outer housing, wherein an airflow channel, an e-liquid storage chamber configured for storing an e-liquid and an atomization assembly configured for atomizing the e-liquid are arranged inside the outer housing; the atomization assembly includes a porous element configured for absorbing the e-liquid from the e-liquid storage chamber, and a heating element configured for heating and atomizing the e-liquid absorbed by the porous element to generate an aerosol; the porous element includes an e-liquid absorbing surface configured for absorbing the e-liquid from the e-liquid storage chamber, and an air inlet surface different from the e-liquid absorbing surface, wherein the air inlet surface is incorporated inside the airflow channel and is configured for allowing air to enter the porous element such that bubbles escape from the liquid absorbing surface to the liquid storage chamber; wherein a bubble guiding element opposite to the e-liquid absorbing surface is further arranged inside the outer housing and includes a bubble guiding surface opposite to the e-liquid absorbing surface, at least a portion of the bubble guiding surface is obliquely arranged in a direction away from the e-liquid absorbing surface, such that the bubbles escaping from the e-liquid absorbing surface are guided towards the direction away from the e-liquid absorbing surface.
Preferably, the porous element partially extends to the e-liquid storage chamber such that the e-liquid absorbing surface is located inside the e-liquid storage chamber.
Preferably, at least a portion of a projection of the bubble guiding surface along the axial direction of the outer housing covers the e-liquid absorbing surface of the heating element.
Preferably, the bubble guiding surface and the e-liquid absorbing surface are spaced with certain distance, to form an area opposite to the e-liquid absorbing surface and supplying the e-liquid to the e-liquid absorbing surface.
Preferably, a shortest distance between the bubble guiding surface and the e-liquid absorbing surface along the axial direction of the outer housing is greater than 3 mm.
Preferably, the sealing base is arranged extending along a cross section of the outer housing;
the support portion includes a first support portion and a second support portion that are arranged on two sides of the sealing base along the cross section of the outer housing; and between the first support portion and the second support portion is formed a channel for the e-liquid to flow to the area from the e-liquid storage chamber.
Preferably, at least a portion of the airflow channel runs through the support portion along the axial direction of the outer housing.
Preferably, at least a portion of the airflow channel has a cross-section area decreased gradually along the flow direction of airflow.
Preferably, the sealing base defines a through accommodation chamber along the axial direction of the outer housing, and the porous element is accommodated inside the accommodation chamber.
The present disclosure further provides an electronic cigarette, including an atomization device configured for atomizing an e-liquid to generate an aerosol, and a power device configured for supplying power to the atomization device, wherein the atomization device includes the atomizer described above.
The above atomizer in the present disclosure uses the bubble guiding element to quickly guide the bubbles emerging from the e-liquid absorbing surface away from the e-liquid absorbing surface, such that the bubbles can be prevented from accumulating near the e-liquid absorbing surface and thus affecting the absorption of e-liquid.
One or more embodiments are illustrated through the image(s) in corresponding drawing(s). These illustrations do not form restrictions to the embodiments.
