[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. It should be understood that the specific embodiments described in this section can only be used to explain the present invention and are not intended to limit the present invention. Specific embodiment 1

[0032] like Figure 1 , Figure 2 As shown, this embodiment discloses an atomizer 100 for electronic cigarettes, which includes a nozzle 110, an oil storage tube 120, a ventilation tube 130, an atomization assembly 140 and an electrical connection seat 150. The oil storage tube 120 is made of glass material, a part of the ventilation tube 130 is arranged inside the oil storage tube 120, and the ventilation tube 130 and the oil storage tube 120 together form an oil storage cavity 121 with an opening 122. The nozzle 110 is connected to the ventilation tube 130 and the opening 122 is sealed. The electrical connection seat 150 is used to connect an external power supply (refer to Figure 7 As shown in Figure 3 As shown, the electrical connection seat 150 includes a plastic card seat 151, a first electrode 152 and a second electrode 153. The card seat 151 is integrally formed with a folded edge 154. The first electrode 152 is fixed on the card seat 151 and is located at an end away from the folded edge 154. The first electrode 152 is provided with a connection structure for connecting an external power supply. The first electrode 152 and the second electrode 153 are insulated and connected by a sleeve insulator 155.

[0033] like Figure 3 , Figure 4 As shown, the atomizing assembly 140 includes a heating element 141 and an oil absorbing member 142. The heating element 141 has two electrical connection ends 1411, and the two electrical connection ends 1411 are electrically connected to the first electrode 152 and the second electrode 153 respectively. In this embodiment, the oil absorbing member 142 is made of ceramic material, and the heating element 141 is disposed in the oil absorbing member 142. Figure 3 , Figure 4 As shown, the vent pipe 130 is provided with an oil inlet hole 131 communicating with the oil storage chamber 121, and the atomizer assembly 140 is arranged in the vent pipe 130 so as to absorb the liquid smoke-generating substance (such as smoke oil) flowing out of the oil inlet hole 131. Figure 5As shown, 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, and the second end 1422 is sleeved with an elastic sealing sleeve 144. The portion 1423 of the middle side surface of the oil suction member 142 that is not covered by the sealing sleeves 143 and 144 is close to the oil inlet hole 131, so as to absorb the smoke oil flowing in from the oil inlet hole 131. After the atomizer assembly 140 is arranged in the vent pipe 130, the sealing sleeves 143 and 144 both abut against the inner wall of the vent pipe 130. The outer diameter of the portion of the oil suction member 142 that is covered by the sealing sleeves 143 and 144 is smaller than the outer diameter of the portion of the oil suction member 142 that is not covered by the sealing sleeves 143 and 144. In this embodiment, the outer diameter of the portion of the oil suction member 142 that is close to the oil inlet hole 131 is close to the inner diameter of the space in the vent pipe 130 where the atomizer assembly 140 is arranged.

[0034] like Figure 4 As shown, the sealing sleeve 143 is provided with two convex rings 1431 surrounding the sealing sleeve 143 on the surface contacting the vent pipe 130, and the sealing sleeve 144 is provided with two convex rings 1441 surrounding the sealing sleeve 144 on the surface contacting the vent pipe 130. The purpose of providing the convex rings 1431 and convex rings 1441 is to improve the assembly quality of the sealing sleeves 143 and 144 and optimize the oil leakage prevention effect of the sealing sleeves 143 and 144.

[0035] like Figure 3 , Figure 4 As shown, a limiting step column 132 and a protrusion 133 protrude from the outer side surface of the ventilation pipe 130. The step column 132 and the protrusion 133 are located at one end of the ventilation pipe 130 and define a groove 134 on the outer side surface of the ventilation pipe 130. The oil storage pipe 120 is provided with a radial flange 123 at the end connected to the ventilation pipe 130. The electrical connection seat 150 is provided with a radial folded edge 156 at the end connected to the ventilation pipe 130. Both the flange 123 and the folded edge 156 are sleeved on the outer side surface of the ventilation pipe 130 and fixed in the groove 134. Specifically, in this embodiment, the outer diameter of the step column 132 is larger than the inner diameter of the flange 123 and smaller than the inner diameter of the oil storage tube 120, and the step column 132 is located in the oil storage cavity 121; the inner diameter of the flange 123 is larger than the outer diameter of the protrusion 133, so that the flange 123 abuts against the first sealing ring 160 after passing through the protrusion 133, and at this time, the first sealing ring 160 is deformed to seal the oil storage cavity 121. The flange 123 can pass through the protrusion 133 and abut against the first sealing ring 160, and the folded edge 156 passes through the protrusion 133 through elastic deformation and abuts against the flange 123 and the protrusion 133.

[0036] like Figure 2 , Figure 4As shown, the two ends of the vent pipe 130 are respectively sleeved with a first sealing ring 160 and a second sealing ring 170, and the first sealing ring 130 is located in the groove 134 and abuts against the step column 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 from the connection gap between the step column 132 and the flange 123, and also makes the folded edge 156 press the protrusion 133, so that the flange 123 and the folded edge 156 are clamped and fixed in the groove 134.

[0037] Similarly, in other embodiments, in order to prevent oil leakage from the gap between the step column 132 and the flange 123 , as a replacement for the first sealing ring 160 , the first sealing ring 160 can also be changed to a sealant provided between the step column 132 and the flange 123 to seal the oil storage chamber 121 .

[0038] like Figure 3 As shown, the side of the first electrode 152 is provided with an air hole 1521, the side of the second electrode 153 is provided with an air hole 1531, and the second electrode 152 has a blind hole 1532. In this embodiment, the air hole 1521 is connected to the outside for air intake; the air hole 1531 is connected to the blind hole 1532 for connecting to the airway in the power supply to start the pneumatic switch. The second electrode 153 is located directly below the ventilation pipe 130, and the end face facing the ventilation pipe 130 is a plane. The purpose of this arrangement is to prevent the condensed smoke oil in the ventilation pipe 130 from directly dripping into the air hole 1531 and entering the airway in the power supply.

[0039] like Figure 6 As shown, the folded edge 156 is a claw-like structure composed of a plurality of elastic bodies 1561; the inner diameter of the folded edge 156 (the inner diameter of the defined circle) is smaller than the outer diameter of the protrusion 133 (it can also be set to be slightly smaller than the outer diameter of the groove 134), the surface of the protrusion 133 that contacts the folded edge 156 is substantially perpendicular to the side of the vent 130, and the surface of the folded edge 156 that contacts the protrusion 133 is substantially perpendicular to the side of the vent 130. The substantially vertical arrangement is used to further prevent the electrical connection seat 150 from being separated from the definition of the protrusion 133. In this embodiment, as Figure 3 As shown, during the assembly process, the surface 1331 of the protrusion 133 in contact with the folded edge 156 is a bevel or arc transition surface. The purpose of setting the plane 1331 of the protrusion 133 away from the folded edge 156 as a bevel or arc transition surface is to facilitate the folded edge 156 to pass through the protrusion 133 smoothly and complete the assembly of the electrical connection seat 150.

[0040] like Figure 2 , Figure 3As shown, the suction nozzle 110 is clamped on the vent pipe 130. 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 open port 122. At this time, the second sealing ring 170 is arranged between the suction nozzle 110 and the vent pipe 130, and the second sealing ring 170 abuts against the suction nozzle and the vent pipe; the third sealing ring 180 is arranged between the suction nozzle 110 and the oil storage pipe 130. The second sealing ring 170 and the third sealing ring 180 are preferably made of silicone material and are used to seal the oil storage cavity 121.

[0041] Since the outer side surface of the ventilation pipe 130 protrudes with a limiting step column 132 and a protrusion 133, the oil storage pipe 120 and the electrical connection seat 150 are sleeved on the outer side surface of the ventilation pipe 130 through the flange 123 and the folded edge 156 and fixed in the groove 134, the use of this sleeve-fitting and clamping fixation scheme is simple to assemble, has a low manufacturing and assembly cost, and is convenient for quality control of the finished product. Specific embodiment 2

[0043] like Figure 7 As shown, this embodiment discloses an electronic cigarette 300, which includes an atomizer 100 for forming smoke and a power supply 200 for supplying power to the atomizer 100. In this embodiment, the atomizer 100 and the power supply 200 are connected by threads. The atomizer 100 is the atomizer described in the first specific embodiment.

[0044] The above embodiments are only preferred embodiments of the present invention, which are used to help understand the present invention and should not be construed as limiting the present invention. For those skilled in the art, according to the disclosure and teaching of this specification, without departing from the concept of the present invention, several modifications and improvements can be made, such as any minor improvements or equivalent substitutions made to the structural form or structure of the present invention, and these modifications and improvements should also be regarded as within the scope of protection of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the present invention.
