In this embodiment, the oil absorbing member 142 is made of a ceramic material, and the heating element 141 is provided in the oil absorbing member 142. As shown in fig. 3 and 4, the air tube 130 is provided with an oil inlet 131 communicating with the oil storage chamber 121, and the atomizing assembly 140 is provided in the air tube 130 to suck the liquid smoke substance (e.g., tobacco tar) flowing out from the oil inlet 131. Specifically, as shown in fig. 5, the oil suction member 142 has a first end 1421 and a second end 1422, the first end 1421 is sleeved with an elastic sealing sleeve 143, the second end 1422 is sleeved with an elastic sealing sleeve 144, and a portion 1423 of the middle side surface of the oil suction member 142, which is not covered by the sealing sleeve 143 and the sealing sleeve 144, is close to the oil inlet 131 so as to suck the smoke flowing from the oil inlet 131. After atomization assembly 140 is disposed within vent tube 130, sealing sleeve 143 and sealing sleeve 144 each abut an inner wall of vent tube 130. The outer diameter of the part of the oil sucking member 142 enclosed by the

sealing sleeves

143, 144 is smaller than the outer diameter of the part of the oil sucking member 142 not enclosed by the sealing

sleeves

143, 144. In this embodiment, the outer diameter of the oil sucking member 142 near the oil inlet 131 is close to the inner diameter of the space of the breather pipe 130 where the atomizing assembly 140 is disposed.

As shown in fig. 4, the gland 143 has two collars 1431 surrounding the gland 143 on the side contacting the vent pipe 130, and the gland 144 has two collars 1441 surrounding the gland 144 on the side contacting the vent pipe 130. The purpose of the convex ring 1431 and the convex ring 1441 is to improve the assembling quality of the sealing

sleeves

143 and 144 and optimize the oil leakage prevention effect of the

sealing sleeves

143 and 144.

As shown in fig. 3 and 4, a limiting step column 132 and a protrusion 133 protrude from the outer side surface of the vent pipe 130, the step column 132 and the protrusion 133 are located at one end of the vent pipe 130 and define a groove 134 on the outer side surface of the vent pipe 130, a flange 123 is radially arranged at one end of the oil storage pipe 120 connected to the vent pipe 130, a flange 156 is radially arranged at one end of the electrical connection seat 150 connected to the vent pipe 130, and both the flange 123 and the flange 156 are sleeved on the outer side surface of the vent pipe 130 and fixed in the groove 134. Specifically, in the present embodiment, the outer diameter of the step post 132 is larger than the inner diameter of the flange 123 and smaller than the inner diameter of the reservoir tube 120, and the step post 132 is located in the reservoir chamber 121; the inside diameter of the flange 123 is larger than the outside diameter of the protrusion 133 so that the flange 123 abuts against the first seal 160 after passing through the protrusion 133, and at this time, the first seal 160 is deformed to seal the oil storage chamber 121. The flange 123 can pass through the protrusion 133 and abut against the first seal ring 160, and the flange 156 passes through the protrusion 133 and abuts against the flange 123 and the protrusion 133 through elastic deformation.

As shown in fig. 2 and 4, a first sealing ring 160 and a second sealing ring 170 are respectively sleeved at two ends of the vent pipe 130, and the first sealing ring 130 is located in the groove 134 and abuts against the step post 132 and the flange 123. The first sealing ring 160 compresses the step column 132 and the flange 123 by generating deformation to prevent oil leakage in a connection gap between the step column 132 and the flange 123, and simultaneously, the flange 156 compresses the protrusion 133, so that the flange 123 and the flange 156 are clamped and fixed in the groove 134.

Similarly, in other embodiments, in order to prevent oil leakage from the gap between the step column 132 and the flange 123, instead of the first sealing ring 160, the first sealing ring 160 may be modified to provide a sealing adhesive between the step column 132 and the flange 123 to seal the oil storage chamber 121.

As shown in fig. 3, the side surface of the first electrode 152 is provided with an air hole 1521, the second electrode 152 is provided with a blind hole 1532, and the side surface of the second electrode 153 is provided with an air hole 1531. In this embodiment, the air hole 1521 is communicated with the outside for air intake; the air hole 1531 is connected to the blind hole 1532 for connecting to an air passage in the power supply to activate the pneumatic switch. The second electrode 153 is located right below the breather pipe 130, and an end surface facing the breather pipe 130 is a flat surface. This is done to prevent condensed smoke from the breather tube 130 from dripping directly into the air hole 1531 and entering the air passage in the power supply.

As shown in fig. 6, the flap 156 is a claw-like structure composed of a plurality of elastic bodies 1561; the inside diameter of flap 156 (the inside diameter of the defined circle) is smaller than the outside diameter of protrusion 133 (and may also be set slightly smaller than the outside diameter of groove 134), the face of protrusion 133 that contacts flap 156 is substantially perpendicular to the sides of vent tube 130, and the face of flap 156 that contacts protrusion 133 is substantially perpendicular to the sides of vent tube 130. The substantially vertical arrangement is employed to further prevent the electrical connector socket 150 from falling out of the definition of the protrusion 133. In this embodiment, as shown in fig. 3, during assembly, the surface 1331 of the protrusion 133 that contacts the flange 156 is a bevel or rounded transition surface. The purpose of providing the protrusion 133 with a slope or a rounded transition away from the plane 1331 of the flange 156 is to facilitate the flange 156 to pass through the protrusion 133 smoothly, and complete the assembly of the electrical connector 150.

As shown in fig. 2 and 3, the suction nozzle 110 is engaged with the vent pipe 130, and after the suction nozzle 110 is connected to the vent pipe 130, the suction nozzle 110 abuts against the oil storage pipe 130 to seal the opening 122. At this time, the second packing 170 is provided between the suction nozzle 110 and the breather pipe 130, and the second packing 170 abuts the suction nozzle and the breather pipe; the third packing 180 is provided between the suction nozzle 110 and the oil storage tube 130. The second and third sealing rings 170 and 180 are preferably made of a silicone material for sealing the oil storage chamber 121.

Because the outer side surface of the vent pipe 130 protrudes with the limiting step column 132 and the protrusion 133, and the oil storage pipe 120 and the electric connection seat 150 are sleeved on the outer side surface of the vent pipe 130 through the turned edge 123 and the turned edge 156 and are fixed in the groove 134, the scheme of adopting the sleeving, clamping and fixing is simple in assembly, low in manufacturing and assembling cost and convenient for quality control of finished products. Because the two ends of the oil suction piece 142 are respectively sleeved with the elastic sealing

sleeves

143 and 144, the middle side part of the oil suction piece 142 close to the oil inlet 131 is not wrapped by the sealing

sleeves

143 and 144 to suck the tobacco tar flowing from the oil inlet 131; after the atomizing assembly 140 is disposed in the vent pipe 130, the sealing

sleeves

143, 144 are tightly pressed against the inner wall of the vent pipe 130, and the sealing

sleeves

143, 144 can well seal the connection gaps between the first end 1421 and the second end 1422 and the vent pipe 130 by deforming, so as to prevent the smoke from leaking from the connection gap between the atomizing assembly 140 and the vent pipe 130.
