Description

The disclosure relates to an atomizer.
A conventional atomizer comprises an e-liquid injector, an air inlet and an air outlet. The e-liquid injector, the air inlet and the air outlet are independent from each other.
US2014007891 A1 teaches an atomizer having a silicon fixing part having grooves on a side wall and outer and inner tubes connected to it. CN210329341 U discloses inhalation holes in a fixing base of an atomizer.
The disclosure provides an atomizer as defined in claim 1.
The disclosure also provides an electronic cigarette comprising the atomizer and a battery assembly.

FIG. 1 is an exploded view of an atomizer in accordance with one embodiment of the disclosure;
FIG. 2 is a schematic diagram of an atomizer in accordance with one embodiment of the disclosure;
FIG. 3 is a sectional view of an atomizer in accordance with one embodiment of the disclosure;
FIG. 4 shows an air flow direction of an atomizer in accordance with one embodiment of the disclosure; and
FIG. 5 is an exploded view of an air passage comprising an air hole, a gap, an air channel, and a groove in accordance with one embodiment of the disclosure.

To further illustrate, embodiments detailing an atomizer are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.
As shown in FIGS. 1-3, the disclosure provides an atomizer comprising a sealing plug 1, a first silicone fixing part 2, a first glass tube 3, a second glass tube 4 disposed in the first glass tube 3, a decorative ring 5, a sealing gasket 6, a ceramic core 7, a second silicone fixing part 8, a fixing base 9, a base 10, an insulation ring 11, a joint 12, an air hole 13, a gap 14, an air channel 15, and a groove 16. The sealing gasket 6 is a hollow structure and disposed in the bottom end of the ceramic core 7. The bottom end of the second glass tube 4 is disposed in the ceramic core and is supported by the sealing gasket 6. The first silicone fixing part 2 is disposed on the top end of the first glass tube 3 to fix the top end of the first glass tube 3 and the top end of the second glass tube 4. Specifically, the first silicone fixing part 2 is disposed between the top end of the second glass tube 4 and the top end of the first glass tube 3. The sealing plug 1 is disposed on the top end of the second glass tube 4. The second silicone fixing part 8 is disposed on the fixing base 9 to support the ceramic core 7. The ceramic core 7 is disposed on the second silicone fixing part 8. The bottom end of the decorative ring 5 is disposed on the fixing base 9. The bottom end of the first glass tube 3 is disposed through the decorative ring 5 and fixed on the fixing base 9. The base 10 is fixed in the bottom cavity of the fixing base 9. The insulation ring 11 is disposed in the bottom cavity of the base 10 to insulate the positive and negative terminals of the ceramic core 7 and fix the negative terminal. The joint 12 is disposed in the insulation ring 11 to fix the positive terminal.
When in use, the e-liquid is injected into the second glass tube 4 and permeates the surface of the ceramic core 7, while no liquid drop forms between the second glass tube 4 and the first glass tube 3. The air hole 13 is disposed on the fixing base 9. The gap 14 is disposed on the second silicone fixing part 8. The air channel 15 is disposed on the ceramic core 7. The groove 16 is disposed on the first silicone fixing part 2. In an inhaling process, the air enters the fixing base 9 via the air hole 13, passes through the gap 14 of the second silicone fixing part 8, and flows along the air channel 15 of the ceramic core 7. The vapor produced in the ceramic core is driven by the air to flow in the space between the first glass tube 3 and the second glass tube 4, and discharges from the groove 16 of the first silicone fixing part 2 for user's inhaling. In certain embodiments, a mouthpiece is disposed on the top end of the first glass 3 to benefit the user's inhaling of the vapor.
Optionally, the gap 14, the air channel 15, and the groove 16 are a part of the air passage, and can be designed in other forms. For example, the groove 16 is disposed on the inner wall of the first silicone fixing part 2, or is replaced by a plurality of through holes. The first silicone fixing part 2 is fixed in the middle part of the second glass tube 4. The first glass tube 3 is flush with the second glass tube 4, and a mouthpiece is disposed on the top end of the first glass tube 4.
The following advantages are associated with the atomizer of the disclosure:
1. The air and the vapor flow in the space between the first glass tube and the second glass tube, which is a novel design.
2. The atomizer is in the shape of a concave bowl, which is a novel design.
3. The e-liquid can be directly injected into the atomizer, which is easy to operate.
