TECHNICAL FIELD

The present invention relates to the technical field of atomization, and specifically to an electronic atomizing device.

BACKGROUND

An electronic atomizing device mainly includes an atomizer and a main body. The main body supplies power to the atomizer to enable an atomizing assembly in the atomizer to generate heat, so that a liquid stored in the atomizer can be atomized into an aerosol.

DETAILED DESCRIPTION

In order to render a more apparent understanding of technical features, objects, and effects of the present invention, specific embodiments thereof will be described in detail with reference to the accompanying drawings.

As shown inFIG.1toFIG.3, an electronic atomizing device in a preferred embodiment of the present invention includes an atomizer1and a main body2which are connected with each other. A liquid storage cavity11is defined in the atomizer1. An atomizing assembly12is disposed in the atomizer1, and a liquid in the liquid storage cavity11can flow to the atomizing assembly12to be adsorbed.

The main body2includes a puff sensor21and a power supply22. The puff sensor21and the power supply22are electrically connected with the atomizing assembly12. The main body2supplies power to the atomizing assembly12of the atomizer1. The atomizing assembly12heats and atomizes the adsorbed liquid into an aerosol when electrified.

An air passage A fluidly connected to the atomizing assembly12and a starting passage B fluidly connected between the airflow passage A and the puff sensor21are defined in the electronic atomizing device. Generally, the puff sensor21may be a microphone sensor. In other embodiments, the puff sensor21may be another type of airflow sensor.

When a user draws, an air enters the airflow passage A via the air inlet31and flows into the starting passage B. The puff sensor21senses the air flowing, and controls the power supply22to supply power to the atomizing assembly12.

The atomizing assembly12heats and atomizes the liquid into the aerosol. Then the aerosol is carried by the air flowing in the airflow passage A to the nozzle13, to be drawn by the user.

Preferably, the starting passage B defines a receiving groove B1for receiving the condensed aerosol. Therefore, the condensed aerosol is received by the receiving groove B1when flowing into the starting passage B, and is prevented from flowing into the main body2to cause damage to elements such as the power supply2, the puff sensor22and a PCB therein, thereby extending the service life of the main body2.

In this embodiment, the airflow passage A includes an air inlet passage fluidly connected between the atomizing assembly12and an air inlet31. The starting passage B is fluidly connected to the air inlet passage, so that the air enters the starting passage B before entering the atomizing assembly12. In other embodiments, the starting passage B may be fluidly connected to an air outlet passage which is fluidly connected between the atomizing assembly12and the nozzle13.

Preferably, the starting passage B includes a first section B2and a second section B3. The first section B2extends from the airflow passage A in a direction away from the nozzle13. The second section B3and the first section B2are arranged at an angle. The receiving groove B1is defined on one side of the second section B3which is away from the nozzle13.

The condensed aerosol entering the starting passage B will flow to the receiving groove B1under an action of gravity during the flowing process, and will not flow to the puff sensor21via the second section B3, so that the condensed aerosol is prevented from entering the puff sensor21.

In some embodiments, the main body2includes a mounting bracket23and a mounting base24. The puff sensor21is disposed in the mounting base24, and the mounting base24is disposed on the mounting bracket23.

One end of the mounting bracket23is connected with the atomizer1. An end of the mounting bracket23which is adjacent to the atomizer1serves as a sealing end to isolate the puff sensor21and the power supply22from the atomizer1, so that the air can only enter the puff sensor21via the starting passage B.

The power supply22is disposed on the mounting bracket23. The end portion of the mounting bracket23which is adjacent to the atomizer1isolates the power supply22from the atomizer1. The power supply22is electrically connected with the puff sensor21.

The end portion of the mounting bracket23which is adjacent to the atomizer1is provided with structures such as elastic electrodes25to electrically connect the power supply22and the puff sensor21with the atomizing assembly12, whereby electrode holes are avoided at the end portion of the mounting bracket23which is adjacent to the atomizer1. Thus, the liquid cannot flow to the power supply22and the puff sensor21via the electrode holes.

In some embodiments, the electronic atomizing device further includes a casing3which is sleeved outside the main body2and the atomizer1. A periphery of an end portion of the mounting bracket23which is opposite to the atomizer1is in a sealed connection with an inner wall of the casing3.

Furthermore, the air inlet31is defined on a side wall of the casing3. A space or passage is defined between adjacent ends of the main body2and the atomizer1, to allow the air to flow to the atomizing assembly12sequentially through the air inlet31and the space or passage between the main body2and the atomizer1.

Preferably, the first section B2is defined at one end of the mounting bracket23which is proximate to the atomizer1. The first section B extends from the end surface of the mounting bracket23proximate to the atomizer1in a direction away from the atomizer1.

In some embodiments, the mounting base24is disposed at one end of the first section B2which is away from the atomizer1. The second section B3is defined when the mounting base24and the mounting bracket23are assembled, thus the processing difficulty of the second section B3can be reduced. The mounting base24defines an inlet opening241to allow the air to enter the puff sensor21. The starting passage B is fluidly connected to the inlet opening241.

Furthermore, the receiving groove B1is defined in the mounting base24. The nozzle13is disposed at one end of the atomizer1which is away from the main body2. The opening of the receiving groove B1is upward when the user draws, and is able to receive the condensed aerosol and avoid the leakage of the condensed aerosol.

In some embodiments, the mounting bracket23defines a receiving cavity231, to prevent the condensed aerosol from overflowing from the receiving groove B1to the inlet opening241. The receiving cavity231is fluidly connected to the starting passage B and the inlet opening241, and is capable of receiving the liquid that flows in. The condensed aerosol overflowing from the receiving groove B1can be received again by the receiving cavity231, to avoid further flowing to the inlet opening241. Thus the service life of the main body2is further extended.

The receiving cavity231is defined on one side of the mounting bracket23which faces the inlet opening241. A maximum distance from the receiving cavity231to the atomizer1is larger than a maximum distance from the inlet opening241to the atomizer1. Thus the receiving cavity231is capable of receiving the condensed aerosol, and preventing the condensed aerosol from flowing to the puff sensor21via the inlet opening241.

A flange232extending into the airflow passage A is provided circumferentially around a periphery of an end portion of the starting passage B which is fluidly connected with the airflow passage A. Thus the difficulty of flowing into the starting passage B of the condensed aerosol in the airflow passage A is increased, and the condensed aerosol that enters the main body2is reduced. Preferably, the flange232is disposed at one side of the mounting bracket23which is adjacent to the atomizer1.

It is to be understood that the above-mentioned technical features can be used in any combination without limitation.

The above description is merely exemplary of the present invention, and is not intended to limit the scope of the present invention; the equivalent structure or equivalent process transformation on the basis of the present invention and of the drawings may be directly or indirectly applied to other related technical fields and shall all fall within the scope of the present invention.
