Abstract

An electronic cigarette includes a first housing and a second housing detachably connected to the first housing. A battery and a controller are provided in the first housing. A first electrode assembly and a light-emitting unit electrically connected with the controller are provided at an end of the first housing. A smoke vent inserted into and cooperating with the smoke device for water storage is provided at an end of the second housing away from the first housing. At least two atomizers arranged coaxially are detachably inserted into the second housing. Since multiple atomizers are provided coaxially, the amount of smoke atomized by the electronic cigarette is increased effectively. When the light-emitting unit is working, the user can check the remaining amount of cigarette liquid in the electronic cigarette at any time. An electronic hookah is further provided.

First claim

The invention claimed is:

a battery and a controller electrically connected to the battery are provided in the first housing, and a first electrode assembly and a light-emitting unit which are electrically connected with the controller are provided at an end of the first housing facing the second housing, and light enters into the second housing and penetrates the second housing to an outer surface of the electronic cigarette when the light-emitting unit is working, and a touch-controlling display module is provided at an end face of the first housing facing away from the second housing, and the touch-controlling display module is electrically connected to the controller for displaying information of the electronic cigarette, which allows users to control the operation of the electronic cigarette;
a smoke vent, which is inserted into and cooperates with the water storage smoking device, is provided at an end of the second housing away from the first housing, and at least two atomizers, which are arranged coaxially, are detachably inserted into the second housing, and any two adjacent atomizers are connected detachably, and a target atomizer is detachably connected to the first electrode assembly, the target atomizer is one of the atomizers closest to the first battery rod assembly;
each of the atomizers comprises a liquid storage assembly, a second electrode assembly inserted in either end of the liquid storage assembly and an electric heating wire assembly inserted in the liquid storage assembly for atomizing cigarette liquid in the liquid storage assembly, and the second electrode assembly of the target atomizer is electrically connected to the first electrode assembly, and the electric heating wire assembly is electrically connected to the second electrode assembly of the target atomizer.

2. The electronic cigarette according to claim 1 , wherein the liquid storage assembly comprises: a light-transmittable liquid storage cartridge and an atomizing tube inserted in the liquid storage cartridge, and a liquid storage chamber for storing cigarette liquid is enclosed by the liquid storage cartridge, the atomizing tube and the second electrode assembly, and a liquid inlet is provided an end of the atomizing tube away from the first housing at a position where the end is connected to an end wall of the liquid storage chamber, the liquid storage chamber is in communication with an inner chamber of the atomizing tube by the liquid inlet;
the electric heating wire assembly is arranged in the atomizing tube and acquires cigarette liquid from the liquid inlet for atomization.

3. The electronic cigarette according to claim 2 , wherein the liquid storage assembly further comprises a fixing tube and an atomizing ring which are inserted in the atomizing tube, a cigarette liquid buffering space is formed between the atomizing ring and the liquid inlet;
the electric heating wire assembly comprises a wick supported on the fixing tube and extending into the cigarette liquid buffering space and an electric heating wire wound on the wick for atomizing cigarette liquid on the wick, and the atomizing ring is sleeved on the atomizing tube and clamps on the wick, an outer peripheral surface of the atomizing ring elastically abuts against an inner peripheral surface of the atomizing tube.

4. The electronic cigarette according to claim 3 , wherein two ends of the fixing tube are inserted into the second electrode assembly respectively and the fixing tube is woven from glass fiber strands.

5. The electronic cigarette according to claim 2 , wherein a liquid filling port in communication with the liquid storage chamber and a sealing member configured to seal the liquid filling port are provided at an end face of the atomizer.

6. The electronic cigarette according to claim 1 , wherein an elastic sealing layer is provided on an inner circumferential wall of the smoke vent, such that the smoke vent abuts against the water storage smoking device by the elastic sealing layer.

7. The electronic cigarette according to claim 6 , wherein a plurality of elastic protrusions are formed on an inner circumferential wall of the elastic sealing layer at intervals in a direction towards the water storage smoking device.

8. The electronic cigarette according to claim 6 , wherein a threaded structure is formed on the inner circumferential wall of the elastic sealing layer.

9. The electronic cigarette according to claim 3 , wherein a hollow portion of the fixing tube is in communication with a hollow portion of the second electrode assembly so as to form a smoke passageway for passing through the smoke; and
the smoke passageway is in communication with the smoke vent.

10. The electronic cigarette according to claim 1 , wherein a first threaded section is provided on an end face of the first housing facing the second housing; and
a second threaded section matched with the first threaded section is provided on an inner peripheral surface of an end of the second housing facing the first housing, such that the second housing is connected to the first housing by the first threaded section and the second threaded section matched with each other.

11. The electronic cigarette according to claim 1 , wherein a guide groove is provided at an end face of the first housing facing the second housing, and a stuck groove is provided for being in communication with the guide groove;
a sliding catch inserted in the guide groove and slidable along the guide groove is provided at an inner peripheral surface of the second housing facing the first housing, and if the sliding catch slides into the struck groove along the guide groove, the second housing is securely connected to the first housing.

12. The electronic cigarette according to claim 4 , wherein a hollow portion of the fixing tube is in communication with a hollow portion of the second electrode assembly so as to form a smoke passageway for passing through the smoke; and
the smoke passageway is in communication with the smoke vent.

13. An electronic hookah, comprising a water storage smoking device having a smoke inlet and a smoke outlet, wherein the water storage smoking device is placed vertically in use and the smoke inlet is located at an upper end of the water storage smoking device, and wherein the electronic hookah further comprises an electronic cigarette configured to be inserted into and cooperate with a water storage smoking device to atomize cigarette liquid for a user to smoke, comprising: an outer housing, wherein the outer housing comprises a first housing and a second housing detachably connected to the first housing, the cross-sectional area of an end face of the first housing away from the second housing is larger than a cross-sectional area of the second housing;
