Figure 3 yes Figure 2 A schematic cross-sectional view of the provided atomizer.

[0062] See also Figure 1a 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 and is used to drive the atomizer 100 according to a preset driving mode. The atomizer 100 is used to atomize an atomization matrix to generate an aerosol when powered on.

[0063] Specifically, the electronic atomization device 300 further includes a handle 201 and a vent 202, the host 200 is connected to the handle 201 through the vent 202, the atomizer 100 has a socket 15, the handle 201 has a plug 15' and an air hole (not shown), the plug 15' 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.

[0064] 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 assembly 2; the atomizer 100 also includes a nozzle 3. The liquid storage tank 1 is used to store the atomized matrix, and the liquid storage tank 1 has a liquid outlet 11. The atomizing assembly 2 is arranged at the liquid outlet 11 of the liquid storage tank 1, and is used to atomize the atomized matrix to generate an aerosol when powered on. The atomizing assembly 2 has a first air outlet 21, and the aerosol generated by the atomization of the atomizing assembly 2 flows out through the first air outlet 21.

[0065] 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 plurality of second air inlets 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 plurality of second air inlets 332 are arranged at intervals in the circumferential direction around the first air inlet 331, such as being arranged at equal intervals. The air gathering chamber 34 is connected to the first air inlet 331 and the second air inlet 332. The aerosol generated by atomization of the atomizer assembly 2 flows through the first air outlet 21 of the atomizer assembly 2 and the first air inlet 331 of the mixer 31 in sequence and enters the mixing chamber 33. The external gas in the air gathering chamber 34 enters the mixing chamber 33 through the first air inlet 331 and the plurality of second air inlets 332 of the mixer 31 and flows to the second air outlet 333 of the mixing chamber 33 after mixing with the aerosol. The adapter 32 includes a third air inlet 321 and a nose inlet 322 arranged opposite to each other. The third air inlet 321 of the adapter 32 is connected to 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 mixing with the external gas enters the adapter 32 through the third air inlet 321 and finally flows to the nose inlet 322 to be inhaled by the user.

[0066] 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 plurality of second air inlets 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 in the prior art that the aerosol generated by the atomization component 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.

[0067] 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 plurality of second air inlets 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 inner wall of the mixing chamber 33, that is, forming a blocking airflow, which can block the aerosol in the mixing chamber 33 and the inner wall of the mixing chamber 33, so that the aerosol contacts the inner 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.

[0082] In this embodiment, one end of the second air inlet 332 away from the first air inlet 331 is flush with the inner side surface of the first annular flange 373, so that the external gas entering through the second air inlet 332 can better block the aerosol entering through the first air inlet 331 from contacting the side wall of the mixing chamber 33, that is, the inner surface of the first annular flange 373, and more effectively prevent the aerosol from contacting the side wall of the mixing chamber 33 and condensing.

The air outlet channel 323 can also be used to store the gas after the external gas and the aerosol are mixed. It can be understood that the annular protrusion 326 surrounding the third air inlet 321 and spaced from the annular side wall 324 of the adapter 32 is set on the surface of the bottom wall 325 of the adapter 32 near the nose inlet 322, which can effectively prevent the liquid after the aerosol condenses in the air outlet channel 323 from flowing back to the mixing chamber 33, causing the atomization sheet 23 to be unable to emit mist normally, and effectively improve the atomization effect.

The aerosol formed by atomization of the atomization component 2 can enter the mixing chamber 33 through the first air inlet port 331, so that the external gas and the aerosol can be mixed in the mixing chamber 33, so as to accelerate the aerosol through the external gas, so that the aerosol can flow more smoothly to the nose entrance 322 and be inhaled by the user, thereby reducing the deposition of aerosol inside the nozzle 3, improving the utilization rate of the aerosol, and solving the problem in the prior art that the aerosol generated by atomization of the atomization component is not easy to flow smoothly to the air outlet of the nozzle.

[0096] In some embodiments, see Figures 16 to 18 , Fig.16 It is a structural schematic diagram of another embodiment of the electronic atomization device provided by the present application; Fig.17 yes Fig.16 A schematic diagram of the internal structure of the main unit and handle of the electronic atomization device shown; Fig.18 yes Fig.16 A schematic diagram of the internal structure of the handle of the electronic atomization device shown; Fig.19 yes Fig.16The system block diagram corresponding to the electronic atomization device shown.

[0097] For details, see Fig. 20 and Fig.21 , Fig. 20 It is a schematic diagram of the position of the soft palate and the nasal cavity when the user exhales or inhales; Fig.21 It is a schematic diagram of the position of the soft palate and the nasal cavity when the user exhales or inhales through the nose; the applicant has found that the atomized matrix is ​​sent into and deposited in the nasal cavity after atomization, and can break through the blood-brain barrier through the olfactory area and reach the brain at a close distance. The drug takes effect quickly and the drug utilization rate is higher. Moreover, when the user exhales or inhales through the mouth, the soft palate will rise relative to the throat, separating the nasal cavity from the throat. When the user exhales or inhales through the nose, the soft palate will sag, allowing the airflow to pass through the nasal cavity. Based on this, the present application designs an active air intake microporous electronic atomization device for the nose, which generates corresponding positive or negative pressure when the mouth exhales or inhales, and starts the electronic atomization device 300 to actively atomize the aerosol into the user's nasal cavity; and because the soft palate is lifted when the mouth exhales or inhales, the nasal cavity and the throat are separated, thereby reducing the aerosol from entering the lungs through the throat, increasing the deposition rate of the aerosol in the nasal cavity, and improving the utilization rate of the nasal cavity to the aerosol. It should be noted that positive pressure refers to the pressure in a system (such as the air-guided mouthpiece 4 and the air pressure detector 5) being greater than the pressure of the system's surrounding environment; conversely, negative pressure refers to the pressure in a system (such as the air-guided mouthpiece 4 and the air pressure detector 5) being less than the pressure of the system's surrounding environment.

[0098] Specifically, Figures 16 to 19 The electronic atomization device 300 further includes: an air-conducting mouthpiece 4, an air pressure detector 5 and a switch element 20d.

[0099] The air guide mouthpiece 4 is used to be inserted into the user's oral cavity and guide air. The air guide mouthpiece 4 has an air guide channel with two ends open. The air pressure detector 5 is provided in the handle 201, and is connected to the air guide mouthpiece 4, and is electrically connected to the controller 20b, and is used to detect the user's oral breathing state. Among them, the breathing state includes the exhalation state and the inhalation state. The air pressure detector 5 can be an air pressure sensor; the air pressure sensor can detect the exhalation state and the inhalation state of the user's mouth according to the change of the air flow or air pressure in the air guide mouthpiece 4. Usually, when in the exhalation state, the air pressure in the air guide mouthpiece 4 and the air pressure sensor is positive pressure; when in the inhalation state, the air pressure in the air guide mouthpiece 4 and the air pressure sensor is negative pressure. Therefore, the controller 20b is configured to respond to the positive pressure or negative pressure in the air guide mouthpiece 4, and the corresponding oral breathing state is the exhalation state or the inhalation state, control the atomization component 2 in the atomization mechanism to work, and atomize the atomization matrix into an aerosol.

[0100] During specific use, the end of the air-conducting mouthpiece 4 facing away from the air pressure detector 5 is inserted into the user's oral cavity, and at the same time, the nose inlet 322 of the adapter 32 is inserted into the user's nasal cavity; then start to exhale or inhale towards the air-conducting mouthpiece 4; the air pressure detector 5 detects the exhalation or inhalation state, and the controller 20b controls the atomization component 2 to start working, generating aerosol to enter the nasal cavity.

[0101] The above scheme can automatically control the atomization component 2 to start working to form an aerosol when the exhalation or inhalation state of the mouth is detected, thereby realizing the active provision of aerosol by the electronic atomization device 300; at the same time, since the soft palate is lifted when the mouth exhales or inhales, the nasal cavity and the throat are separated, thereby reducing the aerosol entering the lungs through the throat, increasing the deposition rate of the aerosol in the nasal cavity, and improving the utilization rate of the nasal cavity for the aerosol.

[0102] In a specific embodiment, the controller 20b is further configured to control the air pump 20c to start working in response to the positive pressure or negative pressure in the air guide mouthpiece 4, that is, the breathing state of the mouth is the exhalation or inhalation state, so as to realize the automatic air intake of the electronic atomization device 300. The following embodiments are all described by this example.

[0103] The inventors further discovered that although the soft palate can be lifted in either the exhalation or inhalation state of the mouth, thus improving the utilization rate of the nasal cavity for aerosols; however, the mode of linking the spray with the exhalation state of the mouth is more in line with the daily use experience under normal conditions, such as blowing the mist with the mouth. Therefore, the mode of linking the spray with the exhalation state of the mouth, that is, responding to the positive pressure in the air-conducting mouthpiece 4, makes the user's compliance in this mode of administration better, the learning difficulty is lower, and the misoperation rate is greatly reduced. Based on the above advantages, in some embodiments, the controller 20b is further configured to control the air pump 20c and / or the atomization component 2 to work in response to the positive pressure in the air-conducting mouthpiece 4, that is, the breathing state of the mouth is in the exhalation state, so as to realize the operation of the automatic air intake atomization component 2 of the electronic atomization device 300, and atomize the atomization matrix into an aerosol.

[0104] The switch element 20d is electrically connected to the host 200, and is used to control the opening and closing of the host 200, so as to supply power to the air pump 20c and the atomizing assembly 2. The switch element 20d may be a key or a button; after the switch element 20d controls the host 200 to be turned on, that is, to enter the working mode, in the exhalation atomization working mode, the air pressure detector 5 detects the breathing state of the user, and starts the air pump 20c and the atomizing assembly 2 to work during exhalation; in the continuous working mode, the air pump 20c and the atomizing assembly 2 are kept working continuously.

[0105] In this embodiment, the user needs to connect the handle 201 to the atomization mechanism when using it. Under the set operation, for example, the user short presses the switch element 20d of the host 200 to enter the exhalation atomization working mode. At this time, the user inserts the nose inlet 322 of the adapter 32 into the nostril, and needs to hold the air guide mouthpiece 4 in the mouth. When the user exhales, the air flow can be guided through the air guide mouthpiece 4 to transmit the air flow to the handle 201. The air pressure detector 5 in the handle 201 detects the exhalation action and transmits a signal to the controller 20b of the host 200, thereby controlling the air pump 20c to start and generate air flow through the ventilation pipe 202 to enter the mixer 31; at the same time, the atomization mechanism starts to generate aerosol and enters the mixer 31, and the central air flow flowing through the first air inlet 331 and the edge air flow flowing through the second air inlet 332 are mixed with the aerosol entering the mixer 31, and are sent to the user's nasal cavity from the nose inlet 322.

[0106] Of course, in other embodiments, the electronic atomization device 300 may not include the air pressure detector 5. The overall structure of the electronic atomization device 300 can be seen in Figure 1a The controller 20b is configured to, in response to the host 200 being turned on, that is, the electronic atomization device 300 entering the working mode, control the air pump 20c and the atomization component 2 to work to provide aerosol.

[0107] In this embodiment, the present application can also enter the continuous atomization working mode under the set operation, such as long pressing the switch element 20d of the host 200 to turn on the host 200, without the user exhaling. When in use, the nose inlet 322 of the adapter 32 needs to be inserted into the user's nostrils. At the same time, the air pump 20c in the host 200 works, and the atomization mechanism starts to generate aerosol, and the central airflow flowing through the first air inlet 331 and the edge airflow flowing through the second air inlet 332 are mixed with the aerosol entering the mixer 31, and then sent to the user's nasal cavity from the nose inlet 322.

[0108] The electronic atomization device 300 provided in this embodiment includes a main unit 200, an atomization mechanism, an air-conducting mouthpiece 4 and an air pressure detector 5. The main unit 200 includes a controller 20b; the atomization mechanism is electrically connected to the controller 20b, and is used to atomize the atomization matrix into an aerosol; the air-conducting mouthpiece 4 is used to be inserted into the user's oral cavity and to conduct air; the air pressure detector 5 is connected to the air-conducting mouthpiece 4 and is electrically connected to the controller 20b; the controller 20b is configured to control the atomization mechanism to atomize the atomization matrix into an aerosol in response to the positive pressure or negative pressure in the air-conducting mouthpiece 4. In this way, the electronic atomization device 300 can actively control the atomization mechanism to start working when a positive pressure or negative pressure state is detected, so as to form and actively provide an aerosol; at the same time, the positive pressure or negative pressure state is formed when the mouth exhales or inhales; based on the structural characteristics of the human respiratory tract, when the mouth exhales or inhales, the soft palate of the pharynx will rise, separating the nasal cavity and the throat, thereby reducing the aerosol from entering the lungs through the throat, increasing the deposition rate of the aerosol in the nasal cavity, and improving the utilization rate of the nasal cavity for the aerosol.
