As described in the background, conventional electronic atomizers are generally provided with a central tube communicating with the suction nozzle, the central tube being used to form a passage for the flow of aerosol mist. In the actual operation of the atomizer, aerosol mist enters the central tube, and the aerosol generating substrate is easy to leak, so that the aerosol generating substrate and the aerosol mist enter the central tube together to cause liquid leakage. And, if too much aerosol generation substrate has piled up in the center tube, center tube inner passage can be blockked up, leads to the inside atmospheric pressure of electronic atomizer unusual, and the atomizer atomization inefficiency and the aerosol fog that the user sucked also can drop the reduction by a wide margin this moment, and the suction is hard, and user experience feels relatively poor.

In order to solve the above problem, referring to fig. 1, the present application provides an atomizing device 100, and referring to fig. 2 to fig. 5 continuously, the atomizing device 100 includes a first housing 10, a second housing 20, a liquid guiding body 30 and a heating element 40, one end of the first housing 10 has a suction nozzle 11, the second housing 20 is sleeved in the first housing 10 and forms a cavity 21 with an opening inside, the liquid guiding body 30 covers the opening of the cavity 21 and is fixed on the second housing 20, the liquid guiding body 30 has an atomizing surface 32 and has a liquid guiding capability of guiding an aerosol generating substrate in the cavity 21 to the atomizing surface 32, the heating element 40 is in heat conduction connection with the atomizing surface 32, and the aerosol generating substrate guided to the atomizing surface 32 from the cavity 21 is heated and atomized to generate aerosol through the heating element 40.

Referring to fig. 2, the first housing 10 and the second housing 20 define at least one air passage L, and opposite ends of each air passage L are connected between the suction nozzle 11 and the atomizing surface 32. The aerosol mist generated by heating on the atomizing surface 32 side flows to both sides of the atomizing surface 32, flows between the first casing 10 and the second casing 20, flows to the suction nozzle 11 side along the extending direction of the first casing 10, and enters the mouth of the user, and the smoking process is completed. So, this application has cancelled traditional center tube structure through nimble structure that sets up, directly utilizes the assembly structure of first casing 10 and second casing 20 to form air flue L, and is totally independent between air flue L and the cavity 21, can not produce weeping risk and atomizing efficient.

It can be understood that, in the conventional atomization device 100 provided with a central tube, the aerosol airflow will firstly flow through the guiding liquid 30 and then enter the central tube, and at this time, dust and fine particles in the guiding liquid 30 are liable to enter the lungs of the user along with the aerosol airflow, which may cause carcinogenic risk. The application provides an atomizing device 100, the aerosol fog that generates from atomizing surface 32 side is the most direct entry between first casing 10 and the second casing 20 after generating, has avoided the air current to pass through from leading liquid 30 for the air current that gets into in the user's mouth is comparatively pure, does not contain harmful substance, and more environmental protection is healthy.

Specifically, the number of the air passages L is one or more, the first housing 10 and the second housing 20 may be sleeved at intervals, or may be partially attached to and partially disposed at intervals, as long as a gap which can be communicated from the atomizing surface 32 to the suction nozzle 11 exists between the first housing 10 and the second housing 20, so as to form the air passage L through which the aerosol mist flows, and as for the specific shape and number of the air passage L, the present application is not limited herein.

Specifically, in one embodiment, all of the air passages L are disposed around the outer periphery of the second housing 20, and may together form an annular air passage L or a plurality of fan-shaped air passages L. When a closed annular air passage L is formed, after aerosol mist is generated on the atomizing surface 32 side, the aerosol mist is diffused to the air passage L around the periphery of the second housing 20 from the atomizing surface 32 in all directions and is diffused to the suction nozzle 11 from all around, so that the reaction speed of the atomizing device 100 is increased, and the user experience feeling is better.

In one embodiment, referring to fig. 3 and 4, the liquid guiding body 30 has a liquid guiding surface 311 and an atomizing surface 32 which are opposite to each other, the liquid guiding surface 311 opens towards the cavity 21, the atomizing surface 32 is formed on a side of the liquid guiding body 30 away from the cavity 21, and the aerosol-generating substrate stored in the cavity 21 can be guided from the liquid guiding surface 311 side to the atomizing surface 32 side, so as to be heated and atomized by the heating element 40 to generate the aerosol mist. The aerosol mist diffuses outwardly into the air passage L and into the user's mouth.

In this way, the aerosol-generating substrate flow path is from the cavity 21 to the atomizing surface 32, and the aerosol mist flow path is from the atomizing surface 32 to the air passage L, and the two paths are not overlapped and independent, so as to avoid the situation that the liquid permeates into the air passage L, and simultaneously avoid the situation that the gas carries the dust particles in the liquid 30.

Further, referring to fig. 5, the heating element 40 covers the atomizing surface 32, and a bottom heating and atomizing manner is adopted, so that the efficiency is high, the cost is low, the space utilization rate is high, and the structural design scheme is more and more flexible. The heat-generating body 40 can be heating wire, heating net, generate heat piece, generate heat the piece etc. and the material chooses for use the heat conductivity, and the material that the resistance is big can be with the fast material of heat conduction heating nature such as iron chromium aluminium, nickel-chromium, thickness and resistance all can adjust according to the practical application demand, and this application does not do the restriction here.

In one embodiment, referring to figure 2, the second housing 20 further has an inlet 23, the inlet 23 allowing the aerosol-generating substrate to pass through and into the cavity 21. The first housing 10 has an air inlet 13, and the air inlet 13 communicates with the atomizing surface 32.

In practical application, the liquid, solid or paste aerosol generating substrate is injected into the cavity 21 through the injection port 23, the gas enters the atomizing device from the gas inlet 13, the heating element 40 is controlled to be started at the moment, the gas expands under heating, the liquid, solid or paste aerosol generating substrate is extruded to the atomizing surface 32 side from the oil guide surface of the liquid guide 30 so as to be atomized by the heating element 40, and the atomized aerosol mist flows to the suction nozzle 11 along the gas passage L (i.e. arrow direction in the figure) along with the gas flow, so that the smoking process is completed. When the heating element 40 is turned off, the oil guiding of the liquid guiding body 30 is stopped, and at this time, the aerosol generating substrate is stored in the cavity 21 and does not permeate to the atomizing surface 32 side, so that the oil leakage phenomenon in the air passage L is avoided.

In one embodiment, and with reference to figures 3 and 4, the liquid guide 30 has a sump 31 opening towards the cavity 21, the walls of the sump 31 defining a liquid guide surface 311, and aerosol-generating substrate within the cavity 21 flows inwardly into the sump 31 and then collects to penetrate down the walls of the sump 31.

Further, the width of the liquid collection channel 31 is narrowed in the direction of liquid flow to form a peripheral sloping sidewall which provides a flow guide for the aerosol-generating substrate within the cavity 21, so that it can be quickly guided to the bottom of the liquid collection channel 31 to permeate down.

In one embodiment, referring to fig. 2, the atomising device 100 further comprises a seal 50, the seal 50 being provided between the liquid guide 30 and the second housing 20 to prevent the aerosol-generating substrate within the cavity 21 from leaking out of the non-atomising surface 32 into the air passage L. Moreover, because the heating element 40 has the characteristics of high temperature and fast heating when operating, the sealing element 50 needs to be made of a high temperature resistant material, such as fluororubber, nitrile rubber material or other materials, which is not limited herein.

In one embodiment, the atomizing device 100 further includes a microphone assembly, the microphone assembly is disposed in the first housing 10 and is communicated with the suction nozzle 11, and when a negative pressure is generated at the side of the suction nozzle 11, the microphone assembly controls the heating element 40 to be turned on, so as to achieve self-starting of the atomizing device 100.

When the suction nozzle 11 side generates negative pressure, the microphone assembly feeds back an opening signal to the circuit board 80, and at the moment, the battery 70 is electrified to open the electronic atomizer, so that the electronic atomizer is started automatically.

At least one air passage L is defined between the first housing 10 and the second housing 20, and opposite ends of each air passage L are communicated between the suction nozzle 11 and the atomizing surface 32. The aerosol mist generated by heating on the atomizing surface 32 side flows to both sides of the atomizing surface 32, flows between the first casing 10 and the second casing 20, flows to the suction nozzle 11 side along the extending direction of the first casing 10, and enters the mouth of the user, and the smoking process is completed.
