[0029] See attached Figure 1-4, shown is an anti-leakage electronic atomizer, the atomizer 1 includes a shell 2, the shell 2 has an adapted oil storage tank 4, an air flow channel and an atomization component, one end of the air flow channel is a suction section 7, the other end is an air intake section 8, the atomization component is arranged between the suction section 7 and the air intake section 8; the atomization component includes an atomization cover 5 and an oil-conducting cotton 6 wrapped with a heating wire, an axially penetrating cavity is formed in the atomization cover 5, one end of the cavity is connected to the suction section 7, and the other end is connected to the suction section 7. The end is docked with the air intake section 8, the oil-conducting cotton 6 is installed in the cavity, and the atomizing cover 5 is provided with an oil seepage hole 500 to connect the oil storage tank 4 and the oil-conducting cotton 6. The interior of the oil-conducting cotton 6 is hollow so as to connect the suction section 7 and the air intake section 8 to form the air flow channel; a removable sealing rod 3 is arranged in the air flow channel, the head end of the sealing rod 3 is exposed in the suction section 7, and the tail end thereof extends axially downward through the cavity and the inside of the oil-conducting cotton 6 to the air intake section 8.

[0030] The lower end of the inner cavity of the atomizing hood 5 has a mounting portion with a larger radial dimension (larger than the upper end portion near the lower end of the cavity), and the oil-conducting cotton 6 is assembled on the mounting portion. An upper sealing gasket 12 is arranged between the oil-conducting cotton 6 and the top wall of the mounting portion, and a lower sealing gasket 13 is arranged between the oil-conducting cotton 6 and the enclosure 11; the upper sealing gasket 12 and the lower sealing gasket 13 are both annular to fit the sealing rod 3.

[0031] Some existing atomizers 1, especially disposable cigarette cartridges, are mostly split oil storage bins 4 and ceramic atomization cores, which need to be assembled and activated when used. During storage, transportation and static storage, such products often have oil leakage, which affects their use. This atomizer 1 scheme is particularly suitable for disposable electronic cigarette cartridges. In the initial state, the sealing rod 3 extends directly downward from the suction section 7 through the atomization assembly to the air intake section 8. The entire airflow channel of the atomizer 1 is tightly filled with the sealing rod 3, which effectively ensures the overall sealing of the airflow channel. The oil in the oil storage bin 4 basically cannot leak into the airflow channel through the oil guide cotton 6. At the same time, the upper sealing gasket 12 and the lower sealing gasket 13 are sleeved in the cavity in an interference fit manner, and are tightly matched with the sealing rod 3, further preventing the oil from penetrating through the oil guide cotton 6 toward the upper or lower part of the airflow channel, and can effectively prevent oil leakage during the long-term storage, transportation and static storage of the product. When in use, the user applies force to the end of the sealing rod 3 to pull it out, and the airflow channel is opened as a whole so that the airflow can flow smoothly. The smoke oil in the oil storage tank 4 penetrates the oil guide cotton 6 through the oil penetration hole 500, and the heating wire converts the electrical energy into heat energy, so that the atomizer 1 performs atomization, and the airflow enters from the air intake section 8 and passes through the atomization component to output the smoke from the suction section 7. The atomizer 1 scheme has excellent anti-leakage performance, and the sealing rod 3 can be pulled out when in use, and the operation is simple.

[0032] In some embodiments, the top wall of the housing 2 is provided with a sleeve 700 extending inward and downward to form the suction section 7, and the top of the atomizing hood 5 is assembled in the sleeve 700; the bottom of the housing 2 is provided with a base assembly, and the bottom end of the atomizing hood 5 is assembled in the base assembly, and the base assembly is provided with the air intake section 8; the inner wall of the housing 2, the atomizing hood 5 and the base assembly are surrounded by the oil storage tank 4. The two ends of the atomizing hood 5 can be tightly fitted in the sleeve 700 and the base assembly, for example, in an interference fit manner, to enhance the sealing of the assembly.

[0033] In some embodiments, the base assembly includes a sealing seat 9 and a bottom plate 10, both of which are sleeved in the housing 2, the sealing seat 9 is provided with a through hole for the atomizing hood 5 to pass through, the bottom plate 10 is located below the sealing seat 9, and is provided with the air inlet section 8, and the upper surface of the bottom plate 10 is provided with a baffle 11 corresponding to the air inlet section 8, and the baffle 11 is sleeved in the atomizing hood 5. The sealing seat 9 is generally made of silicone and has a certain elasticity. It is interference fit between the inner wall of the housing 2 and the atomizing hood 5 to ensure the sealing effect of the bottom of the oil storage tank 4. The bottom of the atomizing hood 5 passes through the sealing seat 9 to reach the bottom plate 10, and it is sleeved and fixed with the baffle 11 on the bottom plate 10, and the overall structure is assembled stably.

[0034] Furthermore, the base assembly may also include a baffle 900, which is disposed above the sealing seat 9 to bear the oil tank pressure. A hole is set in the middle of the baffle 900 to allow the atomizing hood 5 to pass through, and a clearance fit can be used between the two. In order to stabilize the position of the baffle 900, a positioning column can be set on the sealing seat 9, and the baffle 900 has a corresponding positioning hole, and the two cooperate to prevent the baffle 900 from moving at will.

[0035] In some embodiments, the inner periphery of the upper sealing pad 12 and the lower sealing pad 13 has a shrink flange to fit tightly with the sealing rod 3; further, the bottom surface of the upper sealing pad 12 and the top surface of the lower sealing pad 13 are provided with a plurality of notches to connect to the air flow channel. The setting of the shrink flange ensures the close contact between the corresponding sealing pad and the sealing rod 3; the setting of the notch can enhance the air return performance of the oil guide cotton 6, which is conducive to the comprehensive and uniform penetration of the smoke oil into the entire oil guide cotton 6.

[0036] In some embodiments, a groove is provided at the periphery of the top of the atomizing cover 5, and a sealing ring 14 is sleeved in the groove, which is tightly fitted between the atomizing cover 5 and the sleeve 700. The sealing ring 14 is interference-fitted between the atomizing cover 5 and the sleeve 700, has excellent sealing performance, and effectively prevents the leakage of the smoke oil in the oil storage tank 4.

[0037] In addition, an oil filling port can be provided on the top wall of the housing 2, and the oil filling port is equipped with a rubber plug 15 so as to open and close to replenish the smoke oil. The top of the housing 2 has an adaptive upper cover 16, that is, the upper cover 16 has corresponding holes to avoid interference with the exposure of the head end of the sealing rod 3, and cooperates to form a cigarette holder structure. An electrode nail 17 can be provided on the bottom plate 10, and the electrode nail 17 is connected to the heating wire. The heating wire can pass through the lower sealing pad 13 tightly to reach the position of the electrode nail 17. When the atomizer 1 is assembled with the host, the electrode nail 17 obtains current from the host and transmits it to the heating wire to make it heat up.

[0038] An electric heating suction device is provided, comprising a main unit, wherein the electric heating suction device further comprises the oil leakage-proof electronic atomizer 1 as described in any of the preceding items, so as to be assembled with the main unit.

[0039] In summary, the improved atomizer 1 and the electric heating suction device having the atomizer 1 have good anti-oil leakage effect and are easy to use. Only the sealing rod 3 needs to be pulled out, and there is no need to perform cumbersome assembly actions like split products. This solution is particularly suitable for disposable products.
