[0035] It is understood that the oil-proof air-permeable membrane 14 is mainly made of polytetrafluoroethylene (PTFE), which has a plurality of micropores allowing water vapor and gas molecules to pass through, while preventing the passage of liquid and larger particles. Specifically, the air vent 101 is provided at the upper portion of the oil reservoir 10 to avoid the air supplemented to the oil reservoir 10 generating bubbles in the tobacco tar, and the oil-proof air-permeable membrane 14 is attached to the inner wall of the oil reservoir 10 or the hole wall of the air vent 101 by adhesion.

[0036] As shown in Figure 1 the oil-proof air-permeable membrane 14 covers one end of the air vent 101 communicating with the oil storage cavity 11, the fixed shaft 151 is assembled in the air vent 101 from the other end of the air vent 101, and the connection between the fixed shaft 151 and the membrane flap 152 is in clearance fit with the hole wall of the air vent 101 to reserve an air passage gap between the fixed shaft 151 and the hole wall, and the membrane flap 152 covers the outside of the air vent 101 and is clamped with the fixed shaft 151 on the wall of the oil reservoir 10.

[0037] The user can extract air from the oil reservoir 10 when needed. For example, a negative pressure is formed outside the oil reservoir 10, the membrane flap 152 at least partially separates from the surface of the shell under the action of the negative pressure, opens the air passage gap between the one-way valve 15 and the air vent 101, and the air in the oil storage cavity 11 passes through the oil-proof air-permeable membrane 14 and is discharged to the outside of the oil reservoir 10 through the air passage gap, thereby forming a negative pressure inside the oil reservoir 10, and the pressure in the oil storage cavity 11 is less than the pressure outside the oil reservoir 10, and the tobacco tar is retained in the oil reservoir 10 under the influence of the negative pressure.

[0038] Similarly, the one-way valve 15 is arranged at the end of the air vent 101 close to the oil storage cavity 11, and the oil-proof air-permeable membrane 14 is arranged at the end close to the outside of the oil reservoir 10. The user supplements air inside the oil reservoir 10 through the air vent 101 from the outside of the oil reservoir 10, and the external air impacts the one-way valve 15 through the oil-proof air-permeable membrane 14, and the air passes through the air passage gap to impact the membrane flap 152, and after the deformation of the membrane flap 152, the air passage gap is communicated to the oil storage cavity 11, and the external air enters the oil storage cavity 11 to increase the pressure, and when the pressure in the oil storage cavity 11 is equal to or greater than the external atmospheric pressure, the air squeezes the tobacco tar, and the tobacco tar is released to the place needed through the oil outlet.

[0039] The membrane flap 152 of the one-way valve 15 is made of silica gel or rubber material, so that it can deform correspondingly under the change of air pressure. The membrane flap 152 is connected with the fixed shaft 151, the end of the fixed shaft 151 away from the membrane flap 152 is inserted into the air vent 101, and the fixed shaft 151 and the membrane flap 152 can clamp the wall of the oil reservoir 10, and the membrane flap 152 is attached to the surface of the shell to cover the air vent 101.

[0040] The fixed shaft 151 includes an axially extending proximal end and a distal end, the proximal end is connected with the membrane flap 152, and the distal end has a radially contracted neck portion 153 between the proximal end, the neck portion 153 is in clearance fit with the air passing hole 101 and forms an air passing clearance. The fixed shaft 151 can also be made of silica gel or rubber material, and the fixed shaft 151 and the membrane flap 152 can be integrally formed.

[0041] The one-way valve 15 further includes a valve body 150 in the shape of a barrel, one end of which is open, and the opposite end is closed and provided with a mounting hole 1500, the valve body 150 is mounted in the air passing hole 101, the mounting hole 1500 is in communication with the air passing hole 101, the distal end of the fixed shaft 151 passes through the mounting hole 1500, and an air passing clearance is reserved between the distal end and the proximal end and the hole wall of the mounting hole 1500, and the membrane flap 152 is connected with the proximal end of the fixed shaft 151 outside the shell and covers the mounting hole 1500 or the air passing hole 101.

[0042] The oil-proof and air-permeable film 14 covers the open end to prevent tobacco tar from leaking out of the air passing hole 101.

[0043] In some embodiments, the oil storage compartment 10 is provided with an oil storage cotton 12 having a plurality of micropores in which tobacco tar is stored, which not only reduces the release speed of the tobacco tar, but also avoids noise when the oil storage compartment 10 is shaken.

[0044] The application further provides a cartridge including the oil storage compartment 10 in the above embodiments and an atomization assembly 13, wherein the atomization assembly 13 includes an atomization tube 131 and an atomization core 133, the atomization tube 131 is at least partially arranged in the oil storage compartment 10, an outer wall of the atomization tube 131 and an inner wall of the oil storage compartment 10 define an oil storage cavity 11 therebetween, the atomization tube 131 is provided with an oil inlet hole 132 in communication with the oil storage cavity 11, one end of the oil inlet hole 132 defines an oil outlet of the oil storage cavity 11, and the atomization core 133 is arranged in the atomization tube 131.

[0045] A user can control the pressure in the oil storage cavity 11 by controlling the amount of air in the oil storage compartment 10. For example, when the pressure in the oil storage cavity 11 is increased to be greater than or equal to the pressure in the atomization tube 131 by supplementing air to the oil storage cavity 11, the air squeezes the tobacco tar in the oil storage cavity 11, and the tobacco tar is released from the oil outlet, and the release of the tobacco tar is prevented when the pressure in the oil storage cavity 11 is less than the pressure in the atomization tube 131.

[0046] The application further provides an electronic atomizer having the oil storage compartment 10 or the cartridge in the above embodiments, wherein the electronic atomizer further includes an oil supply compartment 20, an oil supply cavity 21 for storing tobacco tar is formed inside the oil supply compartment 20, and the oil supply compartment 20 or the oil storage compartment 10 is provided with an oil passing tube 22, one end of the oil passing tube 22 is in communication with the oil supply cavity 21, and the other end is in communication with the oil storage cavity 11.

[0047] The oil supply chamber 20 is located below the oil storage chamber 10. When the pressure in the oil storage cavity 11 is greater than or equal to the pressure in the oil supply cavity 21, the tobacco tar in the oil supply cavity 21 cannot be delivered to the oil storage cavity 11 under the action of atmospheric pressure. As shown in Figure 4 When the oil storage cavity 11 forms a negative pressure, the pressure in the oil storage cavity 11 is less than the pressure in the oil supply cavity 21, and the tobacco tar in the oil supply cavity 21 is pumped into the oil storage cavity 11 under the action of negative pressure through the oil passage 22.

[0048] In some embodiments, the bottom of the oil passage 22 is close to the bottom of the oil supply cavity 21.

[0049] In some embodiments, the oil supply chamber 20 is detachably connected with the oil storage chamber 10. As shown in Figure 4 , Figure 5 The oil storage chamber 10 is not easily replaced as part of the electronic atomizer, and a receiving cavity is formed on the upper structure of the oil storage chamber 10. When the oil supply chamber 20 is connected with the oil storage chamber 10, the receiving cavity receives at least a part of the oil supply chamber 20.

[0050] In some embodiments, the above-mentioned electronic atomizer further comprises a fluid distribution device 30. As shown in Figure 3 The fluid distribution device 30 is a vacuum pump, and an air passage 35 is defined between the vacuum pump and the oil storage chamber 10. The air passage 35 is at least partially defined by the air passage hole 101, and the air in the oil storage cavity 11 is supplemented or extracted by the vacuum pump.

[0051] The vacuum pump comprises a valve body 150, an elastic membrane 33, and a driving source. The valve body 150 is provided with an air inlet and an air outlet, and is connected with the elastic membrane 33 to define an air chamber 34 capable of containing air. An air passage is arranged on the valve body 150, and an air pipe is arranged between the valve body 150 and the oil storage chamber 10. The two ends of the air pipe are respectively communicated with the air inlet and the air passage hole 101, and the air outlet is communicated to the outside of the valve body 150. The elastic membrane 33 is driven by the driving source to discharge the air in the air chamber 34 through the air outlet. After the air in the air chamber 34 is discharged, the air chamber 34 forms a negative pressure, the membrane flap 152 is opened under the action of the negative pressure, and the air in the oil storage cavity 11 enters the air chamber 34 through the air passage gap and is discharged from the air outlet under the continuous deformation of the elastic membrane 33.

[0052] The driving source comprises a motor 31 and a cam. The motor 31 has a rotating shaft 32 outputting rotary power, and the cam has at least one protruding convex part. The rotating shaft 32 is connected with the cam. The rotating shaft 32 starts to rotate after the motor 31 is powered on, and the convex part intermittently hits the elastic membrane 33 during the rotation of the motor 31. When the elastic membrane 33 is hit, it deforms towards the air chamber 34, so that the volume of the air chamber 34 of the valve body 150 is reduced, and the air in the air chamber 34 is discharged through the air outlet. Figure 4The air in the oil storage cavity 11 is discharged from the air outlet as indicated by the middle arrow, the air pressure in the valve body 150 is reduced to form a negative pressure state, the air in the oil storage cavity 11 is sequentially extracted into the valve body 150 through the oil-proof air-permeable membrane 14 and the air gap, and is discharged from the air chamber 34 when the cam next time hits the elastic membrane 33.

[0053] Compared with the prior art, the user can control the amount of air in the oil storage cavity 11 to control the pressure of the oil storage cavity 11, and then release the tobacco tar when the pressure of the oil storage cavity 11 is greater than or equal to the pressure in the atomizing pipe 131, and use the negative pressure to extract the tobacco tar in the oil supply cavity 20 into the oil storage cavity 10 when the pressure of the oil storage cavity 11 is less than the pressure of the oil supply cavity 21.
