Abstract

An atomizer includes a housing and a liquid storage cup. The housing has a mouthpiece thereon. The liquid storage cup is provided in the housing and configured for storing tobacco liquid. The liquid storage cup has an opening at one end thereof. A microporous liquid conducting body is plugged inside the opening for conducting the tobacco liquid in the liquid storage cup into an atomizing unit. An atomizing unit is connected to the opening and configured for heating the tobacco liquid to generate aerosol. An air flow channel is provided between the mouthpiece and the atomizing unit. The atomizing unit includes a support, a liquid guiding component located in the support, and at least one vertically arranged heating sheet. The heating sheet includes a side surface in contact with the liquid guiding component.

First claim

What is claimed is:

1. An atomizer, comprising:
a housing having a mouthpiece thereon;
a liquid storage cup provided in the housing and configured for storing tobacco liquid, the liquid storage cup having an opening at one end thereof;
a microporous liquid conducting body plugged inside the opening;
an atomizing unit connected to the opening and configured for heating the tobacco liquid to generate aerosol, the microporous liquid conducting body being configured for conveying the tobacco liquid in the liquid storage cup to the atomizing unit; and
an air flow channel provided between the mouthpiece and the atomizing unit;
wherein the atomizing unit comprises a support, a liquid guiding component located in the support, and at least one vertically arranged heating sheet; the heating sheet comprises a side surface in contact with the liquid guiding component, the liquid guiding component is configured to be in contact with the microporous liquid conducting body to guide the tobacco liquid to the heating sheet, and the support further defines an aerosol outlet configured for discharging the aerosol into the air flow channel.

2. The atomizer according to claim 1 , wherein the liquid guiding component comprises a first liquid guiding piece placed horizontally and a second liquid guiding piece placed vertically, the second liquid guiding piece comprises a side surface attached to the heating sheet, and the first liquid guiding piece is located between the second liquid guiding piece and the microporous liquid conducting body and is horizontally attached to a bottom surface of the microporous liquid conducting body.

3. The atomizer according to claim 2 , wherein the microporous liquid conducting body is made of PE foam material and/or PET fiber, and both the first liquid guiding piece and the second liquid guiding piece are made of non-woven fabrics material.

4. The atomizer according to claim 2 , wherein the atomizer comprises two heating sheets vertically arranged inside the support, the two heating sheets are spaced apart from each other, and each of the heating sheets matches with a correspondent one of the second liquid guiding pieces.

5. The atomizer according to claim 4 , wherein the aerosol outlet is defined at a bottom of the support, and the aerosol outlet is aligned with the two heating sheets.

6. The atomizer according to claim 5 , wherein a heating chamber is provided in the support, two card slots are formed on the inner wall of the heating chamber into which the heating sheets are inserted, and two of the second liquid guiding pieces are provided in the heating chamber, respectively, and are in contact with the corresponding heating sheets.

7. The atomizer according to claim 1 , wherein the support is further provided with two electrode sheets, respectively, which are in contact with the pins of the heating sheets, and the electrode sheets comprise a contact part configured to be in contact with an electrode terminal of the power supply and a bending part configured for inserting into the support to fix the electrode sheets.

8. The atomizer according to claim 7 , further comprising a base mounted in the housing, wherein the base is configured for fixing the atomizing device, the base defines two jacks aligned with the electrode sheets, and the jacks are adapted to be inserted by electrode terminals of a power supply to come into contact with the electrode sheets.

9. The atomizer according to claim 1 , wherein the air flow channel has a size which gradually decreases from downstream to upstream, and has an air flow outlet defined between the housing and the liquid storage cup at an upstream position thereof, and the air flow outlet is communicated with the air flow channel and the mouthpiece.

10. The atomizer according to claim 1 , wherein the heating sheet is a grid-shaped heating sheet or a mesh-shaped heating sheet.

11. An electronic cigarette comprising:
an atomizer; and
a power supply assembly detachably connected with the atomizer,
wherein the atomizer is the atomizer according to claim 1 , the power supply assembly comprises a pair of electrode terminals, and the two electrode terminals are configured for electrically connecting to the heating sheet when the power supply assembly is connected to the atomizer.

12. The electronic cigarette according to claim 11 , wherein the atomizer and the power supply assembly are connected in a snap fit manner, the housing comprises an annular rib in an inner edge of a lower end of the housing of the atomizer, and the annular rib is configured for forming a snap fit connection.
