That is to say, the connection structure between the movable member <NUM> and the support <NUM> is simple, and the friction can be reduced through mating of end surfaces. In this embodiment, an end surface <NUM> is arranged on the boss <NUM>. A gap is left between the disc body <NUM> and the end surface <NUM>, and the height of the gap is less than or equal to <NUM>. Alternatively, in this embodiment, the height of the gap may be <NUM>, so as to achieve a large inhalation resistance and prevent inhalation. In this embodiment, an air inlet hole <NUM> may be arranged on the support <NUM>, and two air inlet holes <NUM> may be arranged. The two air inlet holes <NUM> may be arranged on the boss <NUM> at intervals and symmetrically in a radial direction of the boss <NUM>. The two airflow through holes <NUM> may be arranged in a one-to-one correspondence with the two communication airways <NUM>. The movable member <NUM> may be driven into rotation during the rotation of the vaporization shell <NUM>, so that the communication airway <NUM> can be at least partially in communication with the air inlet hole <NUM>, or misaligned with the air inlet hole <NUM>. That is to say, the air inlet hole <NUM> may be blocked by the disc body <NUM>. The air inlet control mechanism 30c may serve as an airway switch. When the electronic vaporization device is in use, the air inlet hole <NUM> may be opened by rotating the vaporization shell <NUM>, and when not in use, the air inlet hole <NUM> may be closed by rotating the vaporization shell <NUM>, thereby preventing accidental inhalation, preventing condensate from entering the support <NUM>, and reducing the risk of the condensate damaging a mainboard arranged on the support <NUM>.

As shown in <FIG> again, when the electronic vaporization device is not used (that is, before or after use), the vaporization shell <NUM> is rotated in a first direction, and the communication channel <NUM> is misaligned with the liquid flowing hole <NUM>. That is to say, the liquid flowing hole <NUM> is completely blocked by the turntable <NUM>. In this case, the vaporizable liquid medium in the liquid storage cavity <NUM> cannot flow into the heating structure <NUM> from the liquid flowing hole <NUM>. The conductive members <NUM> are misaligned with (do not contact) the conductive components <NUM>, that is, the circuit between the vaporization assembly <NUM> and the power supply assembly B is in a disconnected state, so that the power consumption of the power supply assembly B can be greatly reduced. The communication airway <NUM> may be misaligned with the air inlet hole <NUM>, that is, the air inlet hole <NUM> is completely blocked by the disc body <NUM>, so that the air cannot enter the air inlet post <NUM> from the communication airway <NUM>. That is to say, the air cannot enter the vaporization assembly <NUM>, thereby preventing the accidental inhalation.

As shown in <FIG> again, when the electronic vaporization device is in use, the vaporization shell <NUM> is rotated in a second direction, and during the rotation, the conductive members <NUM> both contact the conductive components <NUM>, that is, the circuit between the vaporization assembly <NUM> and the power supply assembly B is in a connected state. In the process of rotation until the conductive members <NUM> both contact the conductive components <NUM>, the communication channel <NUM> is partially in communication with the liquid flowing hole <NUM>. In this case, the vaporizable liquid medium in the liquid storage cavity <NUM> can flow into the heating structure <NUM> from the liquid flowing hole <NUM>. The communication airway <NUM> may be partially in communication with the air inlet hole <NUM>, that is, external air may enter from the air inlet hole <NUM>, then enter the chamber <NUM> of the vaporization base <NUM> through the communication airway <NUM>, and then enter the vaporization cavity <NUM> from the air inlet post <NUM>. When the conductive members <NUM> both completely contact and are in communication with the conductive components <NUM>, the vaporization shell <NUM> may be continuously rotated in the second direction, so that the communication channel <NUM> is completely in communication with the liquid flowing hole <NUM>. The communication airway <NUM> may be completely in communication with the air inlet hole <NUM>. Certainly, in some other embodiments, the vaporization shell <NUM> is rotated to the set position in the second direction, so that the conductive members <NUM> may also both contact the conductive components <NUM>, and the communication channels <NUM> are completely in communication with both the liquid flowing holes <NUM>. The communication airway <NUM> may be completely in communication with both the air inlet holes <NUM>.

<FIG> show a second embodiment of an electronic vaporization device of the present invention, which is different from the first embodiment in that the conductive structure 30b may be arranged in the power supply assembly B. Specifically, the conductive structure may be rotatably arranged in the battery shell <NUM>, the sleeve portion <NUM> may be omitted, and the disc body <NUM> may be directly arranged on the end surface <NUM> of the boss <NUM> of the support <NUM> to rotate. In this embodiment, the disc body <NUM> may be arranged coaxially with the power supply assembly B. Specifically, the disc body <NUM> may be arranged coaxially with the boss <NUM>, and the center of the disc body <NUM> may be located on the axis of the boss <NUM>.

<FIG> show a third embodiment of an electronic vaporization device of the present invention, which is different from the first embodiment in that the conductive structure <NUM> may not be linked with the vaporization shell <NUM>, and the on/off of the circuit between the vaporization assembly <NUM> and the power supply assembly B is not realized only through rotation. The conductive structure <NUM> may be designed by radial sliding. In this embodiment, the vaporization assembly <NUM> may include a radial direction, and the disc body <NUM> may be slidably arranged in the radial direction of the vaporization assembly <NUM>. It may be understood that, in some other embodiments, the conductive structure <NUM> may not only slide in the radial direction of the vaporization assembly <NUM>, but may also be arranged in the battery shell <NUM> to slide in the radial direction of the power supply assembly B.

As shown in <FIG>, in this embodiment, the limiting engagement protrusion <NUM> on the vaporization shell <NUM> may be omitted. As shown in <FIG> and <FIG>, in this embodiment, a handle <NUM> may be arranged on the disc body <NUM>. Two handles <NUM> may be arranged. The two handles <NUM> may be arranged on two opposite sides of the disc body <NUM>, and may pass out of the battery shell <NUM>. The handle <NUM> may be integrally formed with the disc body <NUM> for a user to push the disc body <NUM> to slide in the radial direction. In this embodiment, a first through hole <NUM> may be arranged on the vaporization shell <NUM>, and the first through hole <NUM> may be used for the handle <NUM> to pass out. In this embodiment, a second through hole <NUM> may be arranged on the battery shell <NUM>, and the second through hole <NUM> may be arranged in a one-to-one correspondence with the two handles <NUM> for the handles <NUM> to pass out.

As shown in <FIG> again, when not in use (that is, before or after use), one of the handles <NUM> may be pushed, so that a length by which the one handle <NUM> passes out of the second through hole <NUM> is greater than a length by which the other handle <NUM> passes out of the second through hole <NUM>, thereby causing the conductive member <NUM> to be misaligned with (not to contact) the conductive component <NUM>, and then turning off the circuit between the vaporization assembly <NUM> and the power supply assembly B.

As shown in <FIG> again, when in use, one of the handles <NUM> may be pushed, so that the lengths by which the two handles <NUM> pass out of the second through hole <NUM> are equivalent, thereby causing the conductive member <NUM> to contact the conductive component <NUM>, and then turning on the circuit between the vaporization assembly <NUM> and the power supply assembly B.

<FIG> show a fourth embodiment of an electronic vaporization device of the present invention, which is different from the third embodiment in that the conductive structure <NUM> may not be limited to radial sliding, and the conductive structure <NUM> may slide in the axial direction of the vaporization assembly <NUM> or the axial direction of the power supply assembly B.

As shown in <FIG>, in this embodiment, a limiting portion <NUM> may be arranged on the disc body <NUM>. The limiting portion <NUM> may be cylindrical and has a hollow structure. The limiting portion may be inserted into an end wall of the support body <NUM> from the boss <NUM>, and is in interference fit with the end wall of the support body <NUM> to limit the axial sliding of the disc body <NUM> and prevent the disc body <NUM> from moving in the radial direction.

As shown in <FIG> again, in this embodiment, the conductive structure further includes a slider <NUM>. The slider <NUM> is slidably sleeved on the battery shell <NUM> and connected to the handle <NUM>. Specifically, the slider may be provided with a hole <NUM> for the handle <NUM> to be inserted and fixed, thereby realizing the engagement with the handle <NUM>. The handle <NUM> may be driven to slide in the axial direction by sliding the slider <NUM> in the axial direction.

When not in use, the slider <NUM> may be slid toward the end away from the vaporizer A, thereby causing the conductive member <NUM> not to contact the conductive component <NUM>, and then turning off the circuit between the vaporization assembly <NUM> and the power supply assembly B.

When in use, the slider <NUM> may be slid toward an end where the vaporizer A is inserted, thereby causing the conductive member <NUM> to contact the conductive component <NUM>, and turning on the circuit between the vaporization assembly <NUM> and the power supply assembly B.
