Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to an atomizing host. Background Art

[0002] At present, electronic cigarettes are mainly used to quit smoking or replace cigarettes. Electronic cigarettes heat the smoke oil to make it atomized, and the atomized smoke oil flows out through the mouthpiece for users to inhale.

[0003] In the related art, an electronic cigarette generally includes an atomizer mainframe, which is provided with an oil filling hole, an oil storage chamber, an atomization chamber and an air inhalation chamber. The oil filling hole is connected to the oil storage chamber, and the atomizer mainframe includes a heating component installed in the atomization chamber. During the operation of the electronic cigarette, the oil in the oil storage chamber flows to the heating component, and the heating component heats the oil, so that the oil forms smoke in the atomization chamber for the user to inhale. During the assembly process of the atomizer mainframe, the oil needs to be injected into the oil storage chamber through an oil filling device, and then the oil filling hole is sealed with an oil sealing member made of silicone or the like to seal the oil storage chamber.

[0004] However, there may be a gap between the silicone used to seal the oil filling hole and the hole wall of the oil filling hole, causing the smoke oil in the oil storage chamber to penetrate outward through the oil filling hole, thereby causing the smoke oil to flow out through the atomizer host.

A heating component 21 is installed in the atomizer chamber 206.

[0045] A first elastic oil sealing portion 22 and a second elastic oil sealing portion 23 are provided in the oil filling hole 204, and the first elastic oil sealing portion 22 and the second elastic oil sealing portion 23 are abutted against each other; in the direction from the oil filling hole 204 to the oil storage chamber 202, the first elastic oil sealing portion 22 and the second elastic oil sealing portion 23 are arranged in sequence; after the oil filling device passes through the first elastic oil sealing portion 22 and the second elastic oil sealing portion 23, the oil filling device partially extends into the oil storage chamber 202 and can inject tobacco oil into the oil storage chamber 202; after the oil filling device leaves the first elastic oil sealing portion 22 and the second elastic oil sealing portion 23, the first elastic oil sealing portion 22 and the second elastic oil sealing portion 23 can be reset and seal the oil filling hole 204 under the action of their own elasticity.

[0046] Through the above structure, the first elastic oil sealing part 22 and the second elastic oil sealing part 23 are arranged in sequence in the oil filling hole 204, so that the first elastic oil sealing part 22 and the second elastic oil sealing part 23 can jointly seal the oil filling hole 204 to make the oil storage chamber 202 more airtight.

[0047] In addition, during the assembly process of the atomizer host 100, the second elastic oil sealing part 23 is first installed into the oil filling hole 204, and then the first elastic oil sealing part 22 is installed on the suction nozzle 10, and then the second elastic oil sealing part 23 is installed into the oil filling hole 204, so that the first elastic oil sealing part 22 and the second elastic oil sealing part 23 are abutted, and at the same time, the suction nozzle 10 is installed on the atomizer assembly 20, and the assembly of the atomizer host 100 is completed.

[0048] The assembled atomizer host 100 can be directly stored in a warehouse. When the atomizer host 100 needs to be filled with oil, the needle of the oil filling device is inserted into the atomizer host 100 from the air inhalation cavity 102, and then the needle passes through the first elastic oil sealing portion 22 and the second elastic oil sealing portion 23 in sequence, and injects the oil into the oil storage cavity 202. Furthermore, in the manufacturing process of the atomizer host 100 in this embodiment, the assembly and oil filling steps can be performed separately, and the assembled atomizer host 100 can be directly stored without injecting oil, thereby reducing the storage cost of the atomizer host 100 after assembly.

[0049] Specifically, the air inhalation cavity 102 runs through the entire suction nozzle 10. The opening of the oil storage cavity 202 faces the direction of the suction nozzle 10, and the oil filling hole 204 is located at the opening of the oil storage cavity 202, and then the oil storage cavity 202 is connected to the outside through the oil filling hole 204 and the air inhalation cavity 102 in sequence, so that after the atomizer host 100 is assembled, the oil filling device can directly extend into the oil storage cavity 202 through the air inhalation cavity 102.

[0050] In this embodiment, the first elastic oil sealing portion 22 and the second elastic oil sealing portion 23 are both made of high-tensile silicone material. The oil storage chamber 202 surrounds the atomizing chamber 206, and the atomizing chamber 206 is located in the middle of the atomizing host 100. There are two oil filling holes 204, which are respectively located on both sides of the atomizing chamber 206. The oil filling holes 204 are circular through holes, and the atomizing chamber 206 is a structure similar to a cylinder.

[0051] In other embodiments, the first elastic oil sealing portion 22 and the second elastic oil sealing portion 23 may also be made of other flexible materials, such as rubber; the oil storage chamber 202 and the atomization chamber 206 may also be separately arranged; the number of oil filling holes 204 may also be other, such as one or three; the oil filling hole 204 may also be other shapes, such as a rectangle or a diamond; the atomization chamber 206 may also be other structures, such as a cuboid.

[0053] Through the above structure, the protrusion 222 abuts against the groove wall of the first inner groove 2302, so that the protrusion 222 and the groove wall of the first inner groove 2302 have a larger abutment area, and the contact point between the first elastic oil sealing portion 22 and the second elastic oil sealing portion 23 is uneven; so that the first elastic oil sealing portion 22 can abut against the second elastic oil sealing portion 23 more tightly, further improving the sealing effect of the first elastic oil sealing portion 22 and the second elastic oil sealing portion 23 on the oil filling hole 204.

[0054] Moreover, the protrusion 222 is embedded in the first inner groove 2302 so that the second elastic oil sealing portion 23 expands and the second elastic oil sealing portion 23 can be more closely attached to the hole wall of the oil filling hole 204 to improve the sealing effect of the second elastic oil sealing portion 23 on the oil filling hole 204.

[0055] Specifically, the shape of the protrusion 222 is adapted to the first inner groove 2302 , and the size of the protrusion 222 is slightly larger than the size of the first inner groove 2302 , so that the protrusion 222 can fill the first inner groove 2302 , and the protrusion 222 can press against the groove wall of the first inner groove 2302 .

[0056] In some embodiments, the protrusion 222 includes a first abutment surface 224, and the first inner groove 2302 includes a second abutment surface 232. The first abutment surface 224 abuts against the second abutment surface 232, and the cross-sectional area of ​​the protrusion 222 gradually decreases in the direction from the first elastic oil sealing portion 22 to the second elastic oil sealing portion 23.

[0057] Through the above structure, the first abutting curved surface 224 and the second abutting curved surface 232 can have a larger contact area, and the surface of the first abutting curved surface 224 is smooth, so that each part of the first abutting curved surface 224 can abut against the second abutting curved surface 232, thereby reducing the possibility of leakage of smoke oil through the gap between the second abutting curved surface 232 and the second abutting curved surface 232, and further improving the airtightness of the atomizer host 100.

[0058] Specifically, in the present embodiment, the protrusion 222 is similar to a semi-elliptical protrusion structure; in other embodiments, the protrusion 222 may also be other structures, such as a hemispherical or wavy shape.

[0061] Through the above structure, during the assembly process of the atomizer host 100, the first sealing silicone 24 is first installed in the suction nozzle 10, and the first mounting frame 26 is installed on the housing 27, and then the second sealing silicone 25 is installed on the first mounting frame 26, so that the second elastic oil sealing part 23 is installed in the oil filling hole 204, and then the suction nozzle 10 and the first sealing silicone 24 are installed in the housing 27, so that the first elastic oil sealing part 22 is also installed in the oil filling hole 204, and the first elastic oil sealing part 22 is abutted against the second elastic oil sealing part 23, and the assembly of the atomizer host 100 can be completed. The first sealing silicone 24 and the suction nozzle 10 can be assembled separately, and at the same time, the second sealing silicone 25, the first mounting frame 26 and the housing 27 can be assembled separately, so the atomizer host 100 in this embodiment is easy to assemble.

[0067] Through the above structure, the suction nozzle 10 and the mounting boss 262 clamp the first sealing silicone 24 and the second sealing silicone 25, so that the protrusion 222 and the groove wall of the first inner groove 2302 are pressed against each other, making it difficult for the smoke oil to flow out through the gap between the protrusion 222 and the groove wall of the first inner groove 2302, so as to improve the sealing performance of the oil storage chamber 202. In addition, the first elastic oil sealing part 22 and the second elastic oil sealing part 23 are installed in the coarse hole section 2042, and the bottom wall of the coarse hole section 2042 can be in contact with the second sealing silicone 25, so that the suction nozzle 10 and the mounting boss 262 can clamp the first sealing silicone 24 and the second sealing silicone 25.
