It should be understood that the detailed description and specific examples, while indicating the embodiments of the invention, are given by way of illustration only.

Detailed description of the preferred embodiment

As shown in fig. 1, fig. 2 and fig. 3, the present invention provides an atomizer 100 for an electronic cigarette, which includes a suction nozzle 110, an oil storage tube 120, a ventilation tube 130, an atomizing element 140, a connecting electrode 150 and an airflow channel 160. One end of vent tube 130 is connected to suction nozzle 110, and the remaining majority of the vent tube is located within reservoir tube 120 and together define an annular reservoir 121. The connection electrode includes a first electrode 151 and a second electrode 152, and the atomizing element 140 includes an oil absorbing member 141 and a heat generating member 142. The oil storage chamber 121 is used for storing the tobacco tar, the oil absorption member 141 is used for absorbing the tobacco tar in the oil storage chamber 121, and the heating member 142 is used for heating the oil absorption member 141 to heat and atomize the tobacco tar absorbed by the oil absorption member 141 to form smoke. The heat generating element 142 has two electrical leads electrically connected to the first electrode 151 and the second electrode 152 separately. The first electrode 151 and the second electrode 152 are fixedly connected through an insulating member, and the insulating member is made of a flexible material. In this embodiment, the exposed portion of the first electrode 151 is provided with a connecting thread, the exposed surface of the first electrode 151 is provided with an air inlet 1511 for air intake, the suction nozzle 110 is provided with an air outlet 111, and the air inlet 1511 and the air outlet 111 are communicated with the air flow channel 160.

As shown in fig. 2, 3 and 4, a check valve 170 is further disposed in the air flow passage 160, and the check valve 170 is located between the connection electrode 150 and the atomization element 140. The check valve 170 includes a base 171 and a boss 172, and the check valve 170 is fixed in the air flow passage 160 by the base 171. When the nebulizer 100 is drawn by a user, airflow passes through the airflow channel 160, and the one-way valve 170 opens; when not being sucked, no air flow passes through the air flow passage 160, and the check valve 170 is closed to block the air flow passage 160, thereby preventing the dripping soot from flowing out from the connection electrode 150.

Specifically, the check valve 170 is a flexible member, the base 171 and the boss 172 are integrally formed, and the outer diameter of the boss 172 is smaller than that of the base 171. The base 171 is fitted on the inner wall of the airflow passage 160 in an interference manner, and a buffer space 161 is formed between the protruding column 172 and the inner wall of the airflow passage 160. The one-way valve 170 is further provided with a blind hole 173 and a notch 174, an opening 1731 of the blind hole 173 is positioned on the end face of the base body 172, the closed end of the blind hole 173 is close to the end face of the convex column 171, and the notch 174 is positioned at the closed end and is communicated with the blind hole 173; when there is air flow in the air flow passage 160, the cutout 174 is opened, and when there is no air flow, the cutout 174 is closed.

As shown in fig. 2 and 4, the protruding pillar 172 includes a sidewall 1721 parallel to the extending direction of the slit 174, and the sidewall 1721 is disposed in two parallel. In this embodiment, the thickness of the closed end of the protruding pillar 171 is the same as the thickness of the sidewall 1721, and the thickness of the sidewall 1721 is thinner than the thickness of the other side of the protruding pillar 172.

Because the check valve 170 is disposed in the airflow passage 160; when there is airflow through the airflow channel 160 (the atomizer 100 is being drawn by a user), the check valve 170 is opened, and when there is no airflow through the airflow channel (not being drawn), the check valve 170 is closed to block the airflow channel 170, so that the smoke escaping from the atomizing element 140 can be prevented from escaping from the airflow channel 160. In addition, due to the provision of the buffer space 161, the smoke oil overflowing from the atomizing element 140 also flows to the buffer space 161, reducing the risk of smoke oil flowing out of the connection electrode 150 through the check valve 170.
