[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following exemplary embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention. In addition, the embodiments and features in the embodiments of the present invention may be combined with each other without conflict.

[0020] like Figure 1-2 As shown, an optional embodiment of the utility model provides an electronic atomization device, including a main body 2 and an atomization part 1 detachably arranged on the main body 2, a mounting cavity 10 is arranged at the bottom of the atomization part 1, the atomization part 1 includes an oil storage part 19 installed in the mounting cavity 10, a refueling channel 11 connected to the mounting cavity 10, a heating chamber 12 connected to the refueling channel 11, and also includes an anti-backflow component arranged on the refueling channel 11.

[0021] This embodiment is provided with a backflow prevention component. When in use, the atomizing part 1 is reversed to allow the atomized liquid in the oil storage part to flow into the heating chamber 12 in one direction. When it is reversed again, the atomized liquid that has flowed into the heating chamber 12 is prevented from flowing back into the oil storage part 19.

[0022] like Figure 2 As shown, an optional embodiment of the utility model, the anti-backflow assembly includes a positioning portion 110 installed on the upper wall of the refueling channel 11, a clamping portion 111 sleeved on the fixing portion 110 and moving up and down in the refueling channel 11, and a limiting portion 112 arranged below the positioning portion 110 to limit the movable range of the clamping portion 111. Under normal circumstances, the clamping portion 111 is pressed against the upper end surface of the limiting portion 112 under the action of gravity to block the connection between the installation cavity 10 and the refueling channel 11.

[0023] In this embodiment, when the atomizing portion 1 is inverted, the clamping portion 111 is affected by gravity and moves with the fixing portion 110, away from the limiting portion 112, and the atomized liquid is poured into the refueling channel from the limiting portion to the heating chamber 12. When returning to the normal position, the clamping portion 111 is affected by gravity and moves with the fixing portion 110 to press the limiting portion 112 to block the atomized liquid from flowing into the oil storage portion 19.

[0024] like Figure 2 As shown, an optional embodiment of the utility model, the refueling channel 11 is provided with a guide portion 113. In this embodiment, when the atomizing unit 1 is inverted, the atomized liquid is guided by the guide portion 113 to pour into the heating chamber 12, and when the atomizing unit 1 is returned to the normal position, the excess liquid in the heating chamber 12 flows out of the heating chamber along with the guide portion 113, thereby ensuring heating safety.

[0025] like Figure 2 As shown, an optional embodiment of the utility model, the atomizing part 1 further includes a suction nozzle 13, a heating component 120 is arranged in the heating chamber 12, and the inner wall of the suction nozzle 13 extends into the heating chamber 12 and is sleeved with the heating component 120. In this embodiment, the suction nozzle is connected with the heating component 120 to prevent the atomizing part 1 from flowing out along the suction nozzle 13 when the atomizing part 1 is inverted, so that the suction nozzle can inhale the smoke generated by the heating component 120 heating the atomizing liquid.

[0026] like Figure 2 As shown, an optional embodiment of the utility model, the limiting portion 112 is a protruding annular member formed by the inward contraction of the end of the installation cavity 10, and the oil storage portion 19 is inserted into the installation cavity 10 and abuts against the lower end of the limiting portion 112. In this embodiment, the limiting portion is provided to limit the follow-up range of the pressing portion 111 to prevent it from falling off, and at the same time, the oil storage portion 19 abuts against its lower end surface to enhance the sealing performance of the installation of the oil storage portion 19.

[0027] like Figure 2As shown, in an optional embodiment of the present invention, the clamping portion 111 is a metal block, the upper end surface of the clamping portion 111 is dome-shaped, and the lower end is in an inverted cone shape and extends into the limiting portion 112.

[0028] In this embodiment, the clamping part 111 made of metal is pressed in the limiting part 112 by gravity, which increases the sealing performance; the dome-shaped design of the upper end surface of the clamping part 111 helps to restore the inverted state, and the clamping part can quickly return to the clamped and sealed state to avoid sticking to the top wall of the positioning part due to liquid tension and not falling. The density of the clamping part 111 is higher than the density of the atomized liquid, which prevents the clamping part 111 from floating upward when wrapped by the reflux atomized liquid, and the reflux atomized liquid flows into the oil storage part 19.

[0029] like Figure 2 As shown, an optional embodiment of the utility model, the inner wall of the installation cavity 10 has an internal thread, and the oil storage portion 19 is also provided with an external thread matching the internal thread of the installation cavity 10. In this embodiment, the oil storage portion 19 will not fall off and prevent leakage by providing mutually matching thread structures.

[0030] like Figure 2-3 As shown, an optional embodiment of the utility model, the installation cavity 10 is provided with a plurality of anti-disassembly parts 100 in the inner circumference, the oil storage part 19 is provided with a clamping part 190 in the outer circumference, the oil storage part 19 is inserted into the installation cavity 10, and the clamping part 190 is plugged into the anti-disassembly part clamping 100. In this embodiment, the clamping part 190 and the anti-disassembly part 100 are provided to prevent the oil storage part from being replaced to supplement the atomized liquid that does not meet the requirements.

[0031] like Figure 4 As shown, an optional embodiment of the utility model, the bottom surface of the body 2 is provided with an air hole 220, the bottom of the atomizing part is provided with an air inlet 121 connected to the heating assembly 120, and the air hole 220 is connected to the air passage inside the rod body and communicated with the atomizing part air inlet 121. This embodiment realizes heating the atomized liquid to form smoke inhalation by providing a corresponding air inlet channel.

[0032] In an optional embodiment of the utility model, the anti-backflow component is a one-way valve. In this embodiment, the anti-backflow component can be a one-way valve or other device that limits one-way outflow.

[0033] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms without departing from the scope of protection of the utility model and the claims, which all belong to the protection scope of the utility model.
