Abstract

An exemplary spraying atomizing device includes a housing, a liquid tank, a spraying device, a heating element, and a power supply. The housing defines an atomizing chamber. The liquid tank is configured for storing tobacco liquid. The spraying device is configured for spraying the tobacco liquid into the atomizing chamber in a form of liquid particles. The heating element is arranged in the atomizing chamber, and has a heating surface. The heating surface is configured for supporting and heating the liquid particles to form aerosol. The power supply is arranged in the housing, and is configured for feeding the heating element power.

First claim

What is claimed is:

1. A spraying atomizing device, comprising:
a housing, the housing defining an atomizing chamber;
a liquid tank configured for storing tobacco liquid;
a spraying device configured for spraying the tobacco liquid into the atomizing chamber in a form of liquid particles;
a heating element arranged in the atomizing chamber, the heating element having a heating surface, the heating surface being configured for supporting and heating the liquid particles to form aerosol;
a power supply arranged in the housing, the power supply being configured for feeding the heating element power; and
a receiving chamber in the housing below the heating element, wherein the receiving chamber is in communication with the liquid tank, so that the liquid particles, which are not atomized, can flow into the receiving chamber.

2. The atomizing device according to claim 1 , wherein the heating surface faces the spraying device, and is inclined relative to a horizontal direction.

3. The atomizing device according to claim 1 , wherein the spraying device comprises a nozzle, a pressing head, a pump body, and a suction tube connected to an end of the pump body, the pump body is in communication with the tobacco liquid in the liquid tank via the suction tube, an air pressure in the pump body can be changed by pressing the pressing head, such that tobacco liquid can be sprayed and atomized via the nozzle.

4. The atomizing device according to claim 3 , wherein the pump body comprises a main body, a piston in the main body, and a valve body, the piston is hollow and in communication with the nozzle, the piston and the main body cooperatively define a compression chamber, the valve body is arranged in the compression, and configured for controlling entrance of tobacco liquid into the compression chamber.

5. The atomizing device according to claim 4 , wherein the pump body further comprises an annular stage and a spring, the annular stage forms a spraying hole, a top end of the valve body abuts against the annular stage, and a gap is formed between the annular stage and the spraying hole, and a bottom end of the valve body abuts against the spring.

6. The atomizing device according to claim 4 , wherein the valve body comprises a top valve body, a bottom valve body, and a valve bead, part of the bottom valve being nested in the top valve body, the valve bead is sandwiched between the top valve body and the bottom valve body, the bottom valve body is hollow and in communication with the suction tube, the top valve body and the bottom valve body cooperatively define a gap.

7. The atomizing device according to claim 1 , wherein the heating element is made of porous ceramic or porous metal.

8. The atomizing device according to claim 1 , further comprising a mouthpiece, wherein the mouthpiece and the spraying device are arranged at two opposite sides of the heating element.

9. The atomizing device according to claim 1 , further comprising a button configured for adjusting an output wattage of the power supply.

10. A spraying atomizing device, comprising:
a housing, the housing defining an atomizing chamber;
a liquid tank configured for storing tobacco liquid;
a spraying device configured for spraying the tobacco liquid into the atomizing chamber in a form of liquid particles;
a heating element arranged in the atomizing chamber, the heating element having a heating surface, the heating surface being configured for supporting and heating the liquid particles to form aerosol; and
a power supply arranged in the housing, the power supply being configured for feeding the heating element power;
wherein the spraying device comprises a nozzle, a pressing head, a pump body, and a suction tube connected to an end of the pump body, the pump body is in communication with the tobacco liquid in the liquid tank via the suction tube, an air pressure in the pump body can be changed by pressing the pressing head, such that tobacco liquid can be sprayed and atomized via the nozzle.
