Abstract

A vaporizer includes: a liquid storage tube, an inner side wall of the liquid storage tube defining a liquid storage cavity for storing a vaporizable liquid substrate; a sleeve arranged in the liquid storage cavity, an accommodating cavity being arranged in the sleeve, the sleeve having a first surface and a second surface adjacent to the first surface in a circumferential direction, and at least one liquid guiding port on the first surface; a vaporization core arranged in the accommodating cavity for heating and vaporizing the vaporizable liquid substrate; and a seal member accommodated in the accommodating cavity and sandwiched between an outer wall of the vaporization core and a side wall of the sleeve, at least one liquid inlet hole that communicates the at least one liquid guiding port with the vaporization core being arranged in the seal member.

First claim

What is claimed is:

1 . A vaporizer, comprising:
a liquid storage tube, an inner side wall of the liquid storage tube defining a liquid storage cavity configured to store a vaporizable liquid substrate; a sleeve arranged in the liquid storage cavity, an accommodating cavity being arranged in the sleeve, the sleeve having a first surface and a second surface adjacent to the first surface in a circumferential direction, and at least one liquid guiding port on the first surface; a vaporization core arranged in the accommodating cavity and configured to heat and vaporize the vaporizable liquid substrate; and a seal member accommodated in the accommodating cavity and sandwiched between an outer wall of the vaporization core and a side wall of the sleeve, at least one liquid inlet hole that communicates the at least one liquid guiding port with the vaporization core being arranged in the seal member, wherein a distance between the first surface that comprises the at least one liquid guiding port and the inner side wall of the liquid storage tube opposite to the first surface is greater than a distance between the second surface having no liquid guiding port and the inner side wall of the liquid storage tube opposite to the second surface, such that the vaporizable liquid substrate in the liquid storage cavity enters the at least one liquid inlet hole of the seal member through the at least one liquid guiding port that is on the first surface of the sleeve to be in contact with the vaporization core.

2 . The vaporizer of claim 1 , wherein an orthographic projection of a side wall of the at least one liquid guiding port on the seal member is located at a periphery of the at least one liquid inlet hole.

3 . The vaporizer of claim 1 , wherein the sleeve comprises an accommodating portion and a smoke tube, the accommodating cavity is arranged in the accommodating portion, the smoke tube is in communication with the accommodating cavity, and a vapor vaporized by the vaporization core is discharged out of the accommodating cavity through the smoke tube.

4 . The vaporizer of claim 3 , wherein the vaporization core is cylindrical, the accommodating portion is partially cylindrical, the vaporization core and the accommodating portion are coaxially arranged,
wherein a notch configured to communicate an outer peripheral surface of the accommodating portion with at least one end surface of the accommodating portion is arranged on the accommodating portion, and wherein the first surface is a surface of the notch.

5 . The vaporizer of claim 4 , wherein the first surface is a plane, and a distance between the first surface and an axis of the vaporization core is less than a radius of the accommodating cavity.

6 . The vaporizer of claim 4 , wherein the first surface is a plane, a distance between the first surface and an axis of the vaporization core is less than a distance between the second surface and the axis of the vaporization core, and the distance between the first surface and an axis of the vaporization core is greater than a radius of the accommodating cavity, and
wherein a cross-sectional size of the at least one liquid guiding port is greater than a cross-sectional size of the at least one liquid inlet hole.

7 . The vaporizer of claim 1 , wherein a vaporization cavity is arranged in the vaporization core, and
wherein the vaporizer further comprises a heating element arranged in the vaporization cavity and in contact with a side wall of the vaporization cavity, the heating element being configured to heat and vaporize the vaporizable liquid substrate.

8 . The vaporizer of claim 7 , wherein the seal member is sleeved on the outer wall of the vaporization core, and is in an interference fit with the vaporization core.

9 . The vaporizer of claim 8 , wherein the seal member comprises a first seal portion and a second seal portion, the first seal portion is arranged on one end surface of the vaporization core, and is sandwiched between the end surface of the vaporization core and a top wall of the accommodating cavity,
wherein a first air guiding port in communication with the vaporization cavity is arranged on the first seal portion, and wherein the second seal portion is sleeved on an outer peripheral wall of the seal member and is sandwiched between a side wall of the vaporization core and a side wall of the accommodating cavity.

10 . The vaporizer of claim 9 , wherein the seal member comprises a third seal portion connected to the second seal portion and arranged on another opposite end surface of the vaporization core, and
wherein a second air guiding port in communication with the vaporization cavity is arranged on the third seal portion.

11 . The vaporizer of claim 9 , wherein a first annular rib is arranged on an outer end surface of the first seal portion around a periphery of the first air guiding port and sandwiched between an end surface of the first seal portion and a top wall of the accommodating cavity, and/or
wherein a second annular rib is arranged on an outer peripheral surface of the second seal portion, arranged along a circumferential direction of the seal member, and arranged on a side of the at least one liquid inlet hole facing away from the first seal portion, the second annular rib being sandwiched between the second seal portion and the side wall of the accommodating cavity.

12 . The vaporizer of claim 7 , wherein an air inlet channel is arranged in the vaporizer, and
wherein a liquid absorbing member is arranged between the air inlet channel and the vaporization cavity.

13 . The vaporizer of claim 12 , wherein the liquid absorbing member is connected to an end surface of the vaporization core close to the air inlet channel, and
wherein a vent hole in communication with the vaporization cavity is arranged in the liquid absorbing member.

14 . The vaporizer of claim 1 , wherein the seal member is in an interference fit with an inner wall of the accommodating cavity.

15 . The vaporizer of claim 1 , wherein the at least one liquid guiding port comprises at least two liquid guiding ports, the at least two liquid guiding ports being evenly arranged at intervals on an outer side wall of the sleeve,
wherein the at least one liquid inlet hole comprises two liquid inlet holes, and each of the two liquid inlet holes is arranged corresponding to one liquid guiding port of the at least two liquid guiding ports.

16 . The vaporizer of claim 1 , wherein the second surface is arranged to abut against the inner wall of the liquid storage tube, and the first surface is arranged to be spaced from the inner wall of the liquid storage tube.
