Abstract

This application relates to a vaporization device. The vaporization device includes a housing, a top cap, a heating assembly, and a storage compartment. The housing and the top cap define the storage compartment. The top cap surrounds the heating assembly.

First claim

What is claimed is:

1 . A vaporization device comprising:
a housing; a top cap; and a heating assembly, the housing and the top cap defining the storage compartment and the top cap surrounding the heating assembly.

2 . The vaporization device according to claim 1 , wherein the top cap comprises a first portion and a second portion, the first portion comprising a first material and the second portion comprising a second material, the first material being different from the second material.

3 . The vaporization device according to claim 2 , wherein hardness of the first material is less than hardness of the second material.

4 . The vaporization device according to claim 1 , wherein the first portion comprises an elastic material.

5 . The vaporization device according to claim 4 , wherein the elastic material comprises liquid silica gel, and Shore (Shore) hardness of the elastic material is within a range from 40A to 50A.

6 . The vaporization device according to claim 2 , wherein a bonding force between the first portion and the second portion is within a range from 0.1 N/cm 2 (Newton/square millimeter) to 20 N/cm 2 .

7 . The vaporization device according to claim 2 , wherein an inner surface of the storage compartment surrounds the first portion, and the first portion surrounds the heating assembly.

8 . The vaporization device according to claim 2 , wherein the second portion comprises a flange, the first portion being disposed between an inner surface of the storage compartment and the flange.

9 . The vaporization device according to claim 2 , wherein the second portion comprises a perforation, the first portion comprising a protrusion, and the protrusion penetrating through the second portion through the perforation.

10 . The vaporization device according to claim 2 , further comprising:
a heating base comprising a first opening, wherein the heating assembly is in communication with external fluid through the first opening; and a filter screen in direct contact with the first opening.

11 . The vaporization device according to claim 10 , further comprising a first tube, wherein a first end of the first tube defines the first opening, and the first end of the first tube is away from the heating assembly.

12 . The vaporization device according to claim 11 , further comprising a bottom cap, wherein the filter screen is disposed between the first end of the tube and the bottom cap.

13 . A vaporization device comprising:
a housing; a heating assembly; and a top cap engaged with the housing and the heating assembly.

14 . The vaporization device according to claim 13 , wherein the top cap comprises a first portion, a second portion, and a third portion, the first portion and the third portion comprising a first material, and the second portion comprising a second material.

15 . The vaporization device according to claim 14 , wherein the first material comprises liquid silica gel, and Shore (Shore) hardness of the first material is within a range from 40A to 50A.

16 . The vaporization device according to claim 14 , wherein the second portion of the top cap comprises a first opening and a second opening, the first portion of the top cap is disposed on an outer side of the first opening, and the third portion of the top cap is disposed on an inner side of the second opening.

17 . The vaporization device according to claim 14 , wherein the first portion of the top cap is integrally formed with the third portion.

18 . The vaporization device according to claim 14 , wherein an inner surface of the housing surrounds the first portion, and the third portion surrounds the heating assembly.

19 . The vaporization device according to claim 14 , wherein the second portion comprises a flange, and the first portion is located between an inner surface of the housing and the flange.

20 . The vaporization device according to claim 12 , wherein the second portion comprises a perforation, and there is a protrusion between the first portion and the third portion, the protrusion being disposed in the perforation.

21 . The vaporization device according to claim 13 , further comprising:
a bottom cap disposed at a bottom of the housing, wherein the bottom cap comprises a plurality of holes, diameters of the holes being within a range from 0.01 mm to 0.2 mm.
