[0050] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0051] See also Figures 1 to 3 , Figure 1 is a structural schematic diagram of an embodiment of an electronic atomization device provided by the present application, Figure 2 yes Figure 1 The schematic diagram of the atomizer structure provided, Figure 3 yes Figure 2 A schematic cross-sectional view of the provided atomizer.

[0052] See also Figure 1 The present application provides an electronic atomization device 300, which includes a host 200 and an atomizer 100. The host 200 is electrically connected to the atomizer 100 to provide energy to the atomizer 100. The host 200 drives the atomizer 100 according to a preset mode to atomize an aerosol generating matrix to generate an aerosol when powered on.

[0053] Specifically, the host 200 includes a power module (not shown), a control module (not shown), an air pump (not shown), etc. The power module may be an external power source or a battery; a removable power module such as a battery is convenient for portability.

[0054] The electronic atomization device 300 also includes a handle 201 and a wire 202 with a vent. The host 200 is connected to the handle 201 through the wire 202 with a vent. The atomizer 100 has a socket 15, and the handle 201 has a plug (not shown) and an air hole (not shown). The plug of the handle 201 is inserted into the socket 15, so that the atomizer 100 is electrically connected to the host 200. The atomizer 100 has an air inlet channel 35, and the air inlet channel 35 of the atomizer 100 is connected to the air hole of the handle 201, so that the air inlet channel 35 of the atomizer 100 is connected to the air pump, so that the air pump provides external gas to the air inlet channel 35 of the atomizer 100. It can be understood that the air pump can provide the atomizer 100 with external gas at a higher positive pressure, which is more conducive to the mixing of aerosols and the subsequent discharge and utilization of aerosols.

[0055] In some other embodiments, the host 200 may not have an air pump module. The external gas required by the nebulizer 100 enters the nebulizer 100 by relying on the negative pressure inside the nebulizer 100 .

[0056] See also Figure 2 and Figure 3 In this embodiment, the atomizer 100 includes an atomizing mechanism, which includes a liquid storage tank 1 and an atomizing component 2. The atomizer 100 also includes a nozzle 3. The liquid storage tank 1 is used to store an aerosol generating matrix. The liquid storage tank 1 has a liquid outlet 11. The atomizing component 2 is arranged at the liquid outlet 11 of the liquid storage tank 1, and is used to atomize the aerosol generating matrix to generate an aerosol when powered on. The atomizing component 2 has a first air outlet 21, and the aerosol generated by atomization of the atomizing component 2 flows out through the first air outlet 21.

[0057] The nozzle 3 includes a mixer 31 and an adapter 32. The mixer 31 is arranged on one side of the atomizer assembly 2. The adapter 32 is arranged on one side of the mixer 31 and is connected to the first air outlet 21 of the atomizer assembly 2 through the mixer 31. Specifically, the mixer 31 includes a mixing chamber 33, a gas gathering chamber 34 and an air inlet channel 35. The air inlet channel 35 is connected to the gas gathering chamber 34 and is used to input external gas into the gas gathering chamber 34. The mixing chamber 33 is provided with a first air inlet 331, a second air outlet 333 and a second air inlet 332. The first air inlet 331 is arranged corresponding to the first air outlet 21 and is connected to the first air outlet 21. The second air inlet 332 is arranged around the first air inlet 331 along the circumferential direction of the first air inlet 331. The gas collection chamber 34 is connected with the first air inlet 331 and the second air inlet 332. The aerosol generated by the atomization of the atomization component 2 flows through the first air outlet 21 of the atomization component 2 and the first air inlet 331 of the mixer 31 in sequence and enters the mixing chamber 33. The external gas in the gas collection chamber 34 enters the mixing chamber 33 through the first air inlet 331 and the second air inlet 332 of the mixer 31 respectively and flows to the second air outlet 333 of the mixing chamber 33 after mixing with the aerosol. The adapter 32 includes an air outlet channel 323 and a third air inlet 321 and a nose inlet 322 arranged at both ends of the air outlet channel 323. The third air inlet 321 of the adapter 32 is connected with the second air outlet 333 of the mixing chamber 33. The gas after the aerosol flowing out of the mixing chamber 33 through the second air outlet 333 and the external gas mixes with the gas enters the air outlet channel 323 of the adapter 32 through the third air inlet 321, and finally flows to the nose inlet 322 to be inhaled by the user.

[0058] It can be understood that in the present application, an air inlet channel 35 is provided on the mixer 31, and the air inlet channel 35 is connected to the air pump of the host 200, so that the air pump provides external gas to the air inlet channel 35, and the air inlet channel 35 inputs the external gas into the air gathering chamber 34 of the mixer 31, and enters the mixing chamber 33 through the first air inlet port 331 and the second air inlet port 332 respectively, and mixes with the aerosol entering the mixing chamber 33. The external gas input into the mixer 31 by the air inlet channel 35 can accelerate the aerosol in the mixing chamber 33, so that the flow speed of the aerosol is faster, and the external gas carrying the aerosol can flow more smoothly to the nose inlet 322 of the adapter 32, so as to be inhaled by the user. The active air intake of the air inlet channel 35 effectively solves the problem that the aerosol generated by the atomization component of the prior art is not easy to flow smoothly to the air outlet of the nozzle. At the same time, it also effectively avoids the deposition of the aerosol inside the nozzle 3, and avoids the waste of aerosol. Moreover, an adapter 32 is connected to the end of the mixer 31 away from the atomization component 2, and an air outlet channel 323 is arranged inside the adapter 32, so that the aerosol and the external gas can be more fully mixed inside the adapter 32 and then inhaled by the user, which is more conducive to improving the atomization effect. There is a certain distance between the third air inlet 321 of the adapter 32 and the nasal inlet 322, that is, the air outlet channel 323 inside the adapter 32 has a certain length, so that the flow path of the aerosol and the external gas is increased. The air outlet channel 323 inside the adapter 32 can be used to store part of the mixed aerosol, which can effectively avoid waste caused by the user's untimely inhalation.

[0059] Among them, after the aerosol generated by atomization of the atomization component 2 is ejected through the first air outlet 21, the central airflow flowing through the first air inlet 331 can accelerate the aerosol, reduce the deposition of the aerosol inside the mixer 31, and thus make more aerosol ejected from the nose inlet 322. Moreover, by arranging the second air inlet 332 in the circumferential direction around the first air inlet 331, the external gas passing through the second air inlet 332 can flow along the side wall of the mixing chamber 33, that is, forming a blocking airflow, which can block the contact between the aerosol in the mixing chamber 33 and the side wall of the mixing chamber 33, so that the aerosol contacts the side wall of the mixing chamber 33 as little as possible, which can alleviate the condensation and deposition of the aerosol and reduce the formation of condensate.

[0061] See also Figure 4 The liquid storage tank 1 has a liquid storage chamber 12, and the liquid storage chamber 12 is used to store the aerosol generating matrix. The end of the liquid storage tank 1 close to the nozzle 3 has a liquid outlet 11, and the atomizing assembly 2 is arranged at the position of the liquid outlet 11 of the liquid storage tank 1. The aerosol generating matrix flows to the atomizing assembly 2 through the liquid outlet 11 and is atomized. The end of the liquid storage chamber 12 away from the liquid outlet 11 has a liquid injection port 13. In this embodiment, the liquid storage tank 1 also includes a piston 14 and a socket 15 spaced apart from the liquid storage chamber 12. The piston 14 is at least partially arranged in the liquid injection port 13 to block the liquid storage chamber 12. The plug-in part of the handle 201 is inserted into the socket 15 of the liquid storage tank 1 to electrically connect the host 200 with the atomizing assembly 2.

[0062] For details, see Figure 3 and Figure 4 , the atomizing assembly 2 includes an atomizing seat 22, an atomizing sheet 23 and a conductive member 24, the atomizing sheet 23 and the conductive member 24 are mounted on the atomizing seat 22, the atomizing sheet 23 is connected to the liquid storage chamber 12 through the liquid outlet 11, so as to atomize the aerosol generating matrix flowing to the atomizing sheet 23 through the liquid outlet 11. In this embodiment, the atomizing sheet 23 can be a microporous atomizing sheet 23, one end of the conductive member 24 abuts against the atomizing sheet 23, and the other end extends into the jack 15 of the liquid storage tank 1 and is connected to the plug-in member of the handle 201, so that the host 200 is electrically connected to the atomizing sheet 23 of the atomizing assembly 2, so that the atomizing sheet 23 atomizes the aerosol generating matrix to generate aerosol when the power is on. The first air outlet 21 is arranged at one end of the atomizing seat 22 close to the mixer 31, and the aerosol generated by the atomization of the microporous atomizing sheet 23 flows out of the atomizing assembly 2 through the first air outlet 21.

[0063] In this embodiment, Figure 3As shown, the mixer 31 is arranged on the side of the atomizer assembly 2 away from the liquid storage tank 1, and the liquid storage tank 1 and the mixer 31 clamp and fix the atomizer assembly 2. The adapter 32 is arranged on the side of the mixer 31 away from the atomizer assembly 2, the first air inlet 331 and the second air inlet 332 are arranged at one end of the mixing chamber 33 close to the atomizer assembly 2, and the second air outlet 333 is arranged at one end of the mixing chamber 33 away from the atomizer assembly 2.

[0064] For details, see Figures 5 to 8 In this embodiment, the mixer 31 includes a first cover 36 and a second cover 37. The first cover 36 is disposed on a side of the second cover 37 close to the liquid storage tank 1. The first cover 36 and the second cover 37 cooperate to form a gas gathering chamber 34. The first cover 36 is provided with a avoidance port 361 corresponding to the first air outlet 21 of the atomizer assembly 2, so that the first air outlet 21 is connected to the first air inlet 331 through the avoidance port 361. The mixing chamber 33 is provided on the second cover 37, and the second cover 37 is provided with a plurality of second air inlets 332, which are distributed along the circumference of the second cover 37. In this embodiment, the central axis of the atomizer component 2 coincides with the central axis of the mixer 31, the center of the first air outlet 21 is located on the central axis of the atomizer component 2, the center of the avoidance port 361 is located on the central axis of the first cover body 36, and the center of the first air inlet 331 is located on the central axis of the second cover body 37, that is, the first air outlet 21, the avoidance port 361 and the first air inlet 331 are coaxially arranged, so that the aerosol generated by atomization of the atomizer component 2 can smoothly enter the mixing chamber 33 through the first air inlet 331, and the aerosol in the mixing chamber 33 is less likely to contact the side wall of the mixing chamber 33, thereby avoiding condensation and deposition of the aerosol, and the external gas entering the mixing chamber 33 through the first air inlet 331 and multiple second air inlets 332 can also be better mixed with the aerosol. The gas gathering chamber 34 can gather the external gas input by the air inlet channel 35, so that the external gas is evenly distributed in the gas gathering chamber 34, and can flow to the first air inlet 331 and the multiple second air inlets 332 more efficiently and evenly, thereby better accelerating the aerosol and blocking the aerosol from the side wall of the mixing chamber 33, thereby better avoiding condensation and deposition of the aerosol.

[0065] In other embodiments, the second cover body 37 may also be provided with only one second air inlet 332. For example, the second air inlet 332 is provided in a ring shape. The ring-shaped second air inlet 332 is arranged around the outside of the first air inlet 331 and is connected to the air gathering chamber 34, so that the external gas in the air gathering chamber 34 can flow into the mixing chamber 33 through the second air inlet 332.

[0066] Preferably, the projection of the second air inlet 332 on the first cover body 36 is located at the remaining position of the first cover body 36 different from the avoidance port 361, so that the aerosol flowing through the first air outlet 31 of the atomization component 2 through the avoidance port 361 can flow into the mixing chamber 33 through the first air inlet 331 as much as possible, avoiding the aerosol from flowing into the mixing chamber 33 through the second air inlet 332 and contacting the side wall of the mixing chamber 33, which is more conducive to reducing the deposition and waste of aerosol, allowing the aerosol to be more fully inhaled by the user, thereby improving the utilization rate of the aerosol.
