Abstract

The present disclosure relates to a liquid supply for an electronic cigarette. The liquid supply is configured for connecting with an atomizing device. The liquid supply includes a housing, a liquid outlet, a movable valve, and an elastic element. The housing defines a liquid chamber configured for storing tobacco liquid. The housing has an open end configured for connecting with the atomizing device. The liquid outlet is defined in the open end. The movable valve is movably arranged in the open end. The elastic element elastically abuts against the movable valve such that the valve seals the liquid outlet. When the liquid supply is coupled to the atomizing device, the valve is capable of being pushed by the atomizing device to a position where the liquid outlet is opened.

First claim

What is claimed is:

1. A liquid supply for an electronic cigarette, the liquid supply being configured for connecting with an atomizing device, the liquid supply comprising:
a housing defining a liquid chamber configured for storing tobacco liquid, the housing having an open end configured for connecting with the atomizing device;
a liquid outlet defined in the open end;
a movable valve being movably arranged in the open end;
an air pipe oriented along an axial direction of the housing, wherein the valve nests the air pipe; and
an elastic element elastically abutting against the movable valve such that the valve seals the liquid outlet;
wherein when the liquid supply is coupled to the atomizing device, the valve is capable of being pushed by the atomizing device to a position where the liquid outlet is opened.

2. The liquid supply according to claim 1 , wherein the valve is a sealing piece movable along an axial direction of the housing, the elastic element comprises a spring, and an end of the spring abuts against the sealing piece.

3. The liquid supply according to claim 2 , further comprising an assembling holder arranged in the open end, wherein the assembling holder comprises a step portion, the sealing piece hermetically abuts against the step portion, and the liquid outlet is formed between the sealing piece and the step portion when the sealing piece is pushed open.

4. The liquid supply according to claim 3 , wherein the assembling holder defines an annular groove for coupling with the atomizing device by snap fit.

5. An atomizer comprising:
an atomizing device, the atomizing device comprising a main body and an atomizing unit in the main body, the main body having a connecting part configured for engaging with the open end, the connecting part defines at least one liquid inlet; and
a liquid supply in accordance with claim 1 , the liquid supply being detachably connected with the atomizing device, wherein when the atomizing device is connected with the liquid supply, the connecting part pushes the valve to open the liquid outlet, so that the tobacco liquid flows out from the liquid outlet to the liquid inlet; when the atomizing device is detached from the liquid supply, the elastic element forces the valve to seal the liquid outlet.

6. The atomizer according to claim 5 , wherein the connecting part is capable of inserting into the open end of the liquid supply to form a snap-fit connection.

7. The atomizer according to claim 5 , wherein the atomizing unit comprising a heating element and a liquid conducting element in contact with the heating element, the liquid conducting element is configured for conveying the tobacco liquid to the heating element for atomization.

8. The atomizer according to claim 5 , wherein the connecting part defines at least one liquid groove to be opened and exposed at a side wall of the connecting part, and the at least one liquid groove is in communication with the liquid inlet.

9. The atomizer according to claim 8 , wherein the valve defines a gap in an edge matching with the at least one liquid groove.

10. An electronic cigarette, comprising:
an atomizer according to claim 5 ; and
a power supply, a first end of the atomizing device being connected to the liquid supply, and an opposite second end of the atomizing device being connected to the power supply, the power supply being configured for feeding the atomizing device power.

11. The liquid supply according to claim 1 , wherein the movable valve defines at least one gap at an edge thereof in order to allow the liquid chamber being communicable with the liquid outlet through the at least one gap when the liquid outlet is opened.

12. The atomizer according to claim 8 , wherein the movable valve defines at least one gap at an edge thereof in order to match with the at least one liquid groove.
