After continuous research, design, and repeated trial and improvement of samples, the present utility model is finally created.

[0052] Please refer to Figures 1 to 8 The electronic atomizer provided by the embodiment of the present utility model includes an elastic sealing piece 1. The elastic sealing piece 1 can be installed in an oil storage device or on an atomization cavity shell 41.

[0053] The elastic sealing piece 1 is provided with a first blind hole 11 and a second blind hole 12 that extend towards each other, a bottom wall of the first blind hole 11 and a bottom wall of the second blind hole 12 form a to-be-pierced part 13 for the oil guide pin 2 to be inserted through, and the to-be-pierced part 13 is also used to form a self-sealing structure after the oil guide pin 2 is withdrawn to disconnect the first blind hole 11 and the second blind hole 12, so that the first blind hole 11 and the second blind hole 12 are not connected.

[0054] In the embodiment, the oil guide pin 2 passes through the to-be-pierced part 13, so that the tobacco tar flows out of the oil storage device or flows into the atomization core, and after the oil guide pin 2 is withdrawn, the to-be-pierced part 13 rebounds under the action of its own elastic force to form a self-sealing structure, so that the first blind hole 11 and the second blind hole 12 are disconnected. In the embodiment, the structure of the elastic sealing piece 1 is ingeniously arranged, so that the elastic sealing piece 1 can form a self-sealing structure after the oil guide pin 2 is pulled out, disconnect the connection between the first blind hole 11 and the second blind hole 12, and thus avoid oil leakage during replacement of the oil storage device by the user.

[0055] Optionally, at least one side surface of the to-be-pierced part 13 is a concave arc surface, the concave arc surface is closer to the center line of the first blind hole 11, and the deeper the concave arc surface is, the better the sealing effect of the self-sealing structure formed subsequently is.

[0056] The to-be-pierced part 13 is also provided with a separation groove 14, the separation groove 14 divides the concave arc surface into a first arc surface 141 and a second arc surface 142, and the first arc surface 141 and the second arc surface 142 are symmetrically arranged about the separation groove 14.

[0057] It should be noted that when the oil guide pin 2 is inserted, the to-be-pierced part 13 will be divided into two halves along the separation groove 14 to form two self-sealing parts. After the oil guide pin 2 is withdrawn, the two self-sealing parts approach each other under the action of their own elastic force to close the liquid leakage hole pierced by the oil guide pin 2.

[0058] Optionally, the diameter of the first blind hole 11 is not greater than the outer diameter of the oil guide pin 2, and the diameter of the second blind hole 12 is greater than the outer diameter of the oil guide pin 2; the bottom wall of the first blind hole 11 forms a concave arc surface. The diameter of the first blind hole 11 can be smaller than the outer diameter of the oil guide pin 2, so as to improve the sealing effect of the oil guide pin 2 in the inserted state. Of course, the diameter of the first blind hole 11 can be equal to the outer diameter of the oil guide pin 2. Preferably, the diameter of the first blind hole 11 is smaller than the outer diameter of the oil guide pin 2. In the embodiment, the oil guide pin 2 moves upward relative to the elastic sealing element 1, so as to be sequentially inserted into the first blind hole 11, inserted through the to-be-pierced portion 13, and finally inserted into the second blind hole 12. It should be further pointed out that the diameter of the second blind hole 12 is greater than the outer diameter of the oil guide pin 2, so that the two self-sealing portions are pressed into the second blind hole 12 by the oil guide pin 2, and the self-sealing portions are between the hole wall of the second blind hole 12 and the oil guide pin 2. The second blind hole 12 corresponds to a space for accommodating the self-sealing portions, reduces the deformation degree of the self-sealing portions when the oil guide pin 2 is inserted, and enables the two self-sealing portions to more easily recover to the self-sealing structure.

[0059] Optionally, the first blind hole 11 and the second blind hole 12 are coaxial, so that the to-be-pierced portion 13 is more easily formed into the self-sealing structure after being inserted through, that is, the assembly yield of the elastic sealing element 1 is improved; the diameter difference between the second blind hole 12 and the first blind hole 11 is not less than the maximum thickness of the to-be-pierced portion 13, so that the second blind hole 12 can better accommodate the self-sealing portions.

[0060] Optionally, the electronic atomizer further comprises an oil storage shell 3 and an atomization assembly 4, the elastic sealing element 1 is installed on the oil storage shell 3 to form an oil storage cavity; the atomization assembly 4 comprises an atomization cavity shell 41, an oil storage cotton 42, a heating assembly 43, and a battery 44, the battery 44 is used to supply power to the heating assembly 43, the oil storage cotton 42 and the heating assembly 43 are installed in the atomization cavity shell 41; the oil guide pin 2 is installed on the atomization cavity shell 41, the oil guide pin 2 is fixedly connected with the atomization cavity shell 41, and the inner hole of the oil guide pin 2 communicates with the inside of the atomization cavity shell 41. The oil guide pin 2 passes through the elastic sealing element 1, so that the tobacco oil in the oil storage cavity can flow out along the oil guide pin 2.

[0061] In the embodiment, the oil storage device comprises the oil storage shell 3 and the elastic sealing element 1 installed on the oil storage shell 3. When the oil storage device needs to be replaced, the oil storage device is directly pulled out, at this time, the oil guide pin 2 is withdrawn from the elastic sealing element 1 on the oil storage device, and the elastic sealing element 1 automatically seals the pierced liquid leakage hole to avoid oil leakage of the oil storage device; then, the new oil storage device is installed at a suitable position, the oil guide pin 2 pierces the elastic sealing element 1 on the new oil storage device, so that the new oil storage device supplies the tobacco oil to the atomization assembly 4.

[0062] It should be further pointed out that the combination of the elastic sealing element 1 and the oil storage shell 3 forms the oil storage device, which can be beneficial to simplify the installation and improve the efficiency of installation or replacement of the oil storage device.

[0063] Optionally, the oil guide pin 2 has an oil outlet pipe portion 21 inserted into the atomization cavity shell 41, the oil outlet pipe portion 21 has a closed end and an oil outlet hole 201 is formed in the pipe wall; the atomization cavity shell 41 is provided with a liquid flow cavity 401 surrounding the oil outlet pipe portion 21, the cavity wall of the liquid flow cavity 401 is parallel to the outer circumferential surface of the oil outlet pipe portion 21; under the action of no external force, the tobacco tar adheres between the cavity wall of the liquid flow cavity 401 and the outer circumferential surface of the oil outlet pipe portion 21. Generally, the spacing between the outer circumferential surface of the oil outlet pipe portion 21 and the cavity wall of the liquid flow cavity 401 is 0.25mm-0.3mm, so that the viscous tobacco tar can maintain the state of adhering between the cavity wall of the liquid flow cavity 401 and the outer circumferential surface of the oil outlet pipe portion 21 under the action of no external force, and the excessive tobacco tar is prevented from entering the oil storage cotton 42.

[0064] In this embodiment, when the user smokes, a negative pressure will be formed in the inside of the atomization cavity shell 41, at this time, the tobacco tar adhering between the cavity wall of the liquid flow cavity 401 and the outer circumferential surface of the oil outlet pipe portion 21 falls into the oil storage cotton 42 under the action of the negative pressure, so as to supplement the tobacco tar and avoid the case that the atomization assembly 4 is "dry burning". Generally, the amount of oil supplement is equal to the amount of tobacco tar consumption, which ensures that there is no problem of oil leakage or burnt wick.

[0065] Optionally, the oil storage shell 3 is provided with a smoke outlet hole 31, the atomization cavity shell 41 is provided with an atomization pipe 411 for connecting the smoke outlet hole 31; the elastic sealing element 1 is provided with a ventilation hole 100 through which the atomization pipe 411 passes, and the elastic sealing element 1 is in sealing connection with the atomization pipe 411. The atomization pipe 411 passes through the ventilation hole 100, and when the user smokes the mouthpiece of the oil storage shell 3, the atomized gas of the atomization assembly 4 will flow out along the ventilation hole 100 and the smoke outlet hole 31.

[0066] Optionally, the oil storage shell 3 has a smoke pipe portion 32 for sleeving the outer periphery of the atomization pipe 411; the ventilation hole 100 is a stepped hole, including a first sealing hole 101 for sealingly sleeving the outer periphery of the smoke pipe portion 32 and a second sealing hole 102 for sleeving the outer periphery of the atomization pipe 411. As Figure 3 In this embodiment, the elastic sealing element 1 not only plays the role of sealing the oil guide pin 2 and forming a self-sealing structure, but also plays the role of sealing the gap between the atomization pipe 411 and the smoke pipe portion 32.

[0067] Optionally, the atomization cavity shell 41 has an oil storage cotton mounting cavity, and the oil storage cotton 42 is mounted in the oil storage cotton mounting cavity; the oil storage cotton mounting cavity is communicated with the liquid flow cavity 401, and the oil storage cotton 42 does not interfere with the smoke pipe portion 32, so as to prevent the tobacco tar from directly penetrating into the oil storage cotton 42 without negative pressure. The maximum oil absorption capacity of the oil storage cotton 42 is not less than 20% of the volume of the oil storage cotton mounting cavity.

[0068] Optionally, the cross section of the partition groove 14 is isosceles trapezoidal. The bottom width of the partition groove 14 is 0.1-0.5mm, the top width is 0.3-0.9mm, and the depth is 0.5-1mm.
