This application claims priority of the Chinese Patent Application No. 201910403537.5, entitled “Atomizer and Electronic Cigarette”, filed on May 15, 2019, the entire content of which is incorporated herein by reference.
The present disclosure relates to an alternative to cigarettes, and particularly to an atomizer and an electronic cigarette.
An electronic cigarette has the same appearance, smoke, taste, and feel as a cigarette. As tobacco smoking can cause toxic ingredients in the tobacco to enter a user's body along with smoking, which can adversely affect the health of the user and the people around the user. Accordingly, the electronic cigarette, which is mainly used for quitting smoking and replacing cigarettes, has been rapidly popularized.
The existing electronic cigarette includes a battery host and an atomizer. The electronic cigarette can be powered on via an air pressure switch, such that a heating coil in the atomizer is heated to atomize an electronic cigarette liquid (e-liquid) and form smoke steam for the user to smoke. Specifically, an e-liquid storage chamber for storing the e-liquid and a channel for airflow and smoke to pass through are provided inside the atomizer. An e-liquid guiding hole is provided between the e-liquid storage chamber and the channel. The e-liquid in the e-liquid storage chamber is exported through the e-liquid guiding hole to an atomization component in the atomizer. Specifically, an e-liquid guiding cotton element is provided to stick into the e-liquid storage chamber through the e-liquid guiding hole and come into contact with the e-liquid. Alternatively, a ceramic heating element is provided to generate heat. The ceramic heating element is covered with cotton before matching the e-liquid guiding hole, such that the e-liquid in the e-liquid storage chamber flows through the e-liquid guiding hole to the cotton and then is locked and heated by the ceramic heating element. When the electronic cigarette is smoked, the atomization component in the atomizer is powered on to generate high-temperature atomized the e-liquid. The high-temperature atomized e-liquid is formed into droplets and is remained in the atomizer when the high-temperature atomized e-liquid is cooled or is not completely smoked. The e-liquid exported through the e-liquid guiding hole may be adsorbed to wall surfaces of the atomization component and the atomization chamber. When there are more droplets, the droplets may be mixed with the e-liquid adsorbed to the wall surfaces of the atomization component and the atomization chamber to form liquor condensate. When a user smokes, the liquor condensate mixed with the droplets and the e-liquids may be smoked, which affects the taste and experience of smoking. In addition, the liquor condensate may penetrate into the battery host through a base, and corrode a circuit board, which causes a short circuit of the circuit board, and affect a service life of the electronic cigarette.
Based on this, it is necessary to provide an atomizer and an electronic cigarette which are good in taste, good in user experience, simple in assembly, safe and reliable, and can effectively improve the service life.

In an embodiment, an e-liquid guiding hole 1266 is provided in a wall surface between the e-liquid storage chamber 124 and the airflow channel 126. The porous boss 1622 passes through the e-liquid guiding hole 1266 and is in direct contact with the e-liquid storage chamber 124. There is an interference fit between the porous boss 1622 and the e-liquid guiding hole 1266.
In an embodiment, the porous body 1621 has a hollow chamber structure with one end open and the other end closed, and the closed end of the porous body 1621 is adjacent to the base 14. The porous body 1621 is beneficial to collect the liquor condensate and prevent the liquor condensate from leaking out of a bottom portion of the porous body 1621. The porous body 1621 is also beneficial to the secondary atomization of the liquor condensate and prevent the liquor condensate from leaking out of the base 14, thereby improving the taste of the smoke and the safety and reliability of the electronic cigarette. A side wall of the porous body 1621 is provided with a through hole 1624. The through hole 1624 directs air into the atomizer 10 and then into the atomization component 16 through the through hole 1624, to provide air required for the high-temperature atomization.
An outer wall of the porous element 162 is fitted to an inner wall of the airflow channel 126, such that the liquor condensate formed by atomizing the e-liquid at a high temperature accumulates at the porous heating element 164, so as to facilitate the secondary atomization and improve the taste of smoke. At the same time, the liquor condensate is prevented from leaking out of the base 14 and penetrating into the host 20, thereby effectively preventing the liquor condensate from corroding a circuit board, and effectively improving safety, reliability, and service life of the electronic cigarette.
In an embodiment, an outer wall of the porous body 1621 is partially fitted to the inner wall of the airflow channel 126. A gap is preset between the through hole 1624 and the inner wall of the airflow channel 126. That is, air may flow into the airflow channel 126 through the through hole 1624. The air flows through the through hole 1624, and an air intake hole 141 of the atomizer 10 is in communication with the mouthpiece 122 of the atomizer 10, accordingly, the air required for atomization is provided. Since one end of the porous element 162 away from the base 14 is fitted to the airflow channel 126, the air flows through the through hole 1624 into the hollow chamber and is atomized to form smoke for the user to take. The formed liquor condensate accumulates in the porous body 1621 or in the hollow chamber thereof, so as to facilitate the secondary atomization without leaking to the base 14.
The heating element 164 is attached to a hollow inner wall of the porous body 1621, or is embedded in the porous body 1621, which is beneficial for the heating element 164 to atomize when the porous element 162 adsorbs and locks a large amount of the e-liquid, thereby generating more smoke for the user to take, and producing full taste. An electrical contact portion 165 of the heating element 164 protrudes from the closed end of the porous element 162, so as to facilitate a connection between the heating element 164 and an electrode column 149 of the atomizer 10.
Specifically, the porous element 162 is a porous ceramic e-liquid guiding element, a porous glass e-liquid guiding element, or an e-liquid guiding element made of other materials.
In another embodiment, the porous boss 1622 of the porous element 162 may extend in a direction perpendicular to the airflow channel 126. A gap for to air to flow is formed between the porous body 1621 and the airflow channel 126. At the moment, the heating element 164 may be a printed circuit printed on the outer wall of the porous body 1621, and the printed circuit is electrically connected to an electrode column 149 provided in the atomizer 10.
In the present embodiment, the porous body 1621 and the porous boss 1622 are intersected, and a shape of an axial cross section of the porous element 162 is T-shaped, cross-shaped. L-shaped, or Y-shaped. That is, the porous element 162 at least includes a hollow chamber of the porous body 1621 which is in communication with the airflow channel 126 and a porous boss 1622 plugged into the e-liquid guiding hole 1266. The porous boss 1622 has positioning function and e-liquid exporting function.
In the present embodiment, the airflow channel 126 is provided in a middle portion inside the housing 12, and the airflow channel 126 is surrounded by the e-liquid storage chamber 124. At least two e-liquid guiding holes 1266 are symmetrically provided on a wall surface between the e-liquid storage chamber 124 and the airflow channel 126. The porous element 162 is accordingly provided with at least two porous bosses 1622 to plug in and close the e-liquid guiding holes 1266. The porous boss 1622 can direct the e-liquid into the porous element 162 for the heating element 164 to atomize at a high temperature. A symmetrical arrangement of the porous boss 1622 is advantageous to uniformity of the e-liquid guiding of each portion of the porous element 162 and uniformity of high-temperature atomization of the heating element, and is advantageous to balance formation of the smoke and heating portions, improve the taste of smoke, and improve the service life of the heating element 164.
In the present embodiment, the airflow channel 126 includes an atomization chamber 1262 and a smoke channel 1264 communicating with each other. The e-liquid guiding hole 1266 is provided on a wall surface of the atomization chamber 1262. The atomization component 16 is plugged into the e-liquid guiding hole 1266 via the porous boss 1622 and fixed in the atomization chamber 1262. The atomization chamber 1262 is in communication with the air intake hole 141 of the atomizer 10, and the smoke channel 1264 is in communication with a mouthpiece 122 of the atomizer 10.
In the present embodiment, the base 14 includes a supporting seat 142 and a sealing seat 144. The supporting seat 142 is sheathed in the sealing seat 144. The atomization chamber 1262 is provided between the supporting seat 142 and the sealing seat 144. The atomization chamber 1262 and the smoke channel 1264 run through the sealing seat 144 and communicate with each other. As for the arrangement of the supporting seat 142 and the sealing seat 144, on one hand, the atomization component 16 is mounted to the sealing seat 144 before the sealing seat 144 is mounted to the supporting seat 142, thereby simplifying the assembling process and improving the production efficiency; on the other hand, the sealing seat 144 may seal a gap between the e-liquid storage chamber 124 and the supporting seat 142, thereby avoiding leak of the e-liquid. In an embodiment, the sealing seat 144 is made of a silicone material, and there is an interference fit between the sealing seat 144 and a gap between the supporting seat 142 and the housing 12. There is also an interference fit between the porous boss 1622 and the e-liquid guiding hole 1266, thereby improving the sealing performance.

The above-mentioned atomizer 10 and electronic cigarette at least include the following advantages.
The atomization component 16 of the atomizer 10 can be directly plugged into and fixed to the base 14, and the atomization component 16 can be directly plugged into the e-liquid guiding hole 1266 to contact the e-liquid in the e-liquid storage chamber 124, thereby omitting a process of covering the atomizer 10 with cotton, and thus having simple and quick assembly, and saving a cost. In addition, the atomization component 16 is provided to fit an inner wall of the airflow channel 126. The atomization component 16 is powered on to heat and atomize the e-liquid to form smoke. The liquor condensate formed is attached to wall surfaces of the smoke channel 1264 and the porous element 162. When there are more liquor condensates, the liquor condensates are adsorbed to the porous element 162. Since a bottom portion of the porous element 162 is sealed, the liquor condensate can be atomized a second time, thereby avoiding smoking the liquor condensate, and having good taste and good user experience. At the same time, the liquor condensate cannot leak out of the base 14 and penetrate into the host 20, thereby effectively preventing the liquor condensate from penetrating into the host 20 to corrode the circuit board, and effectively improving safety, reliability, and service life of the electronic cigarette.
