[0062] The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not intended to limit the present disclosure.

[0063] In the present disclosure, unless otherwise stated, "inner" and "outer" refer to the inside and outside of the contour of the corresponding component. Among them, X in the attached drawings represents the first direction, and Y represents the second direction. In addition, in the following description, when referring to the attached drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.

[0064] As Figures 1 - 10 shown, the present disclosure provides an atomization device, including an air inlet 9, an air outlet 10, a mixing chamber 12, and a compression module. The mixing chamber 12 is communicated with the air inlet 9 through a gas passage, and the mixing chamber 12 is communicated with the air outlet 10. The compression module is configured to atomize the medium to be atomized through a pressure change and output it to the mixing chamber 12. The atomization device is arranged such that when inhaling at the air outlet 10, the compression module can respond to the inhalation action, atomize the medium to be atomized, and output it to the mixing chamber 12.

[0065] Here, in the present disclosure, the atomization device may include, but is not limited to, an electronic cigarette, a nebulizer for oral or nasal administration, and the medium to be atomized may be e-liquid, medicine.

[0066] Through the above technical solution, through the pressure change, the compression module can compress the medium to be atomized to atomize the medium to be atomized. Compared with the high-temperature atomization of electronic cigarettes in the related art, the present disclosure does not need to atomize the medium to be atomized through high temperature, which can effectively avoid the components in the medium to be atomized from being damaged, and can also extend the service life of the atomization device.

[0067] In addition, since the air outlet 10 is communicated with the air inlet 9 through a gas passage, and the air inlet 9 can be communicated with the outside, when inhaling at the air outlet 10, when inhaling at the air outlet 10, the air inlet 9 can suck the outside air from the gas passage to the air outlet 10, so as to generate a pressure change on the air inlet 9, the air outlet 10, and the gas passage, enabling the compression module to respond to the pressure change brought by the inhalation action, atomize the medium to be atomized, and output it to the mixing chamber 12, reducing the operation steps and being convenient to use.

[0068] In the present disclosure, in order to facilitate the compression atomization of the medium to be atomized, optionally, as Figure 1As shown, the atomizing device further includes an output channel 4, a storage chamber 2, and an input channel 3. The storage chamber 2 is used to store the medium to be atomized. The input channel 3 is adapted to connect the storage chamber 2 and the compression chamber 1. The output channel 4 is adapted to communicate with the compression chamber 1. The compression module may include an atomizing structure 6, a compression chamber 1, and a compression component 5. The atomizing structure 6 may be disposed at the outlet end of the output channel 4. The atomizing structure 6 is adapted to atomize the medium to be atomized discharged from the output channel 4 into the mixing chamber 12. The compression component 5 may include a driving mechanism 501 and a compression member 502. Among them, the driving mechanism 501 is used to drive the compression member 502 to reciprocate in the compression chamber 1, so as to inhale the medium to be atomized in the storage chamber 2 into the compression chamber 1 through the change of the pressure in the compression chamber 1, or discharge the medium to be atomized in the storage chamber 2 to the atomizing structure 6 through the output channel 4.

[0069] With such a setting, the driving mechanism 501 driving the compression member 502 to reciprocate in the compression chamber 1 can reduce the pressure in the compression chamber 1 or increase the pressure in the compression chamber 1. During the process of the pressure in the compression chamber 1 decreasing, the medium to be atomized in the storage chamber 2 can be inhaled into the compression chamber 1 through the input channel 3. During the process of the pressure in the compression chamber 1 increasing, the compression member 502 can compress the medium to be atomized inhaled into the compression chamber 1, so as to atomize and discharge the medium to be atomized through the output channel 4. The atomizing structure 6 can further atomize the medium to be atomized discharged from the output channel 4, which can improve the atomizing effect.

[0070] Optionally, the input channel 3 is set as a one-way channel. In the input channel 3, the medium to be atomized is adapted to flow from the storage chamber 2 to the compression chamber 1. Thus, the medium to be atomized in the storage chamber 2 can flow unidirectionally into the compression chamber 1 through the input channel 3, and the medium to be atomized in the compression chamber 1 cannot flow back into the storage chamber 2 through the input channel 3. The advantage of such a setting is that it can prevent the medium to be atomized from accidentally entering the input channel 3 during the process of the compression member 502 atomizing and discharging the atomizable substance through the output channel 4.

[0071] It can be understood that, in order to facilitate the realization of the function that the medium to be atomized in the storage chamber 2 can only flow unidirectionally to the compression chamber 1 through the input channel 3, optionally, as Figure 1As shown, the input channel 3 has a first communication port 17 communicating with the storage chamber 2 and a second communication port 18 communicating with the compression chamber 1; the atomization device further includes a first one-way communication structure 19, and the first one-way communication structure 19 is adapted to connect or cut off the first communication port 17 and the second communication port 18 so as to open or close the input channel 3. With such a setting, during the process of the pressure in the compression chamber 1 decreasing, the first one-way communication structure 19 can connect the first communication port 17 and the second communication port 18, so that the input channel 3 is opened, and thus the medium to be atomized in the storage chamber 2 can be inhaled into the compression chamber 1 through the input channel 3; during the process of the pressure in the compression chamber 1 increasing, the first one-way communication structure 19 can cut off the first communication port 17 and the second communication port 18, so that the input channel 3 is closed, and thus the medium to be atomized in the compression chamber 1 will not enter the input channel 3 or the storage chamber 2.

[0072] In the present disclosure, there can be various forms of setting for the first one-way communication structure 19, as long as it can satisfy that when the pressure in the compression chamber 1 decreases, the first one-way communication structure 19 can connect the first communication port 17 and the second communication port 18, and when the pressure in the compression chamber 1 increases, the first one-way communication structure 19 can cut off the first communication port 17 and the second communication port 18.

[0073] As an exemplary implementation manner, in combination with Figure 4 and Figure 5 , the first one-way communication structure 19 may include a first mounting member 1901 and a first valve sheet 1902. The first valve sheet 1902 is located in the compression chamber 1. The first valve sheet 1902 has a first through hole 21 and a first blocking portion 22, and the first blocking portion 22 is used to block the second communication port 18. That is to say, the first blocking portion 22 can separate the compression chamber 1 and the input channel 3. In addition, a first mounting hole 20 is provided in the side wall of the compression chamber 1, and the first mounting member 1901 passes through the first through hole 21 and is inserted into the first mounting hole 20. Here, the side wall of the compression chamber 1 may be a part of the following mounting portion 16, and the first mounting member 1901 may be a plug rod and may be in interference fit in the first mounting hole 20. And, the first blocking portion 22 is arranged to be moved away from the second communication port 18 by the medium to be atomized in the storage chamber 2 during the process of the compression member 502 moving in the direction of reducing the pressure in the compression chamber 1.

[0074] Based on the above settings, when the compression member 502 moves in the direction of reducing the pressure in the compression chamber 1, the pressure in the compression chamber 1 decreases and a negative pressure can be formed in the compression chamber 1. A pressure difference is formed between the compression chamber 1 and the input channel 3 separated by the first valve plate 1902, and the atomization medium to be atomized in the storage chamber 2 can exert a squeezing force on the first valve plate 1902 via the input channel 3. When the pressure in the compression chamber 1 continues to decrease, the first blocking portion 22 can be displaced from the second communication port 18 under the squeezing of the atomization medium to be atomized in the input channel 3, so that the second communication port 18 is exposed, and the atomization medium to be atomized in the input channel 3 can enter the compression chamber 1 through the second communication port 18.

[0075] Specifically, in combination with Figure 4 and Figure 5 , the first blocking portion 22 is located in the compression chamber 1. The first blocking portion 22 is used to block one side of the second communication port 18 and abuts against the inner wall of the compression chamber 1, and the first blocking portion 22 can be a metal sheet or a rubber sheet that can elastically deform. Here, the inner wall of the compression chamber 1 can be a part of the following mounting portion 16. That is to say, when the compression member 502 moves in the direction of reducing the pressure in the compression chamber 1, under the continuous squeezing of the atomization medium to be atomized in the input channel 3, the first blocking portion 22 can elastically deform to expose the second communication port 18, so that the atomization medium to be atomized can enter the compression chamber 1 and fill the entire compression chamber 1; when the compression member 502 moves in the direction of increasing the pressure in the compression chamber 1, the compression member 502 can squeeze the atomization medium to be atomized in the compression chamber 1, the first blocking portion 22 can return to its original state, and under the squeezing action of the atomization medium, it abuts against the inner wall of the compression chamber 1, so that the first blocking portion 22 can block the second communication port 18 to separate the compression chamber 1 and the input channel 3.

[0076] It can be understood that in order to enable the first blocking portion 22 to quickly respond to the movement of the compression member 502, optionally, the second communication port 18 is arranged relative to the movement direction of the compression member 502, and the first blocking portion 22 is also arranged relative to the movement direction of the compression member 502.

[0077] As another exemplary embodiment, in combination with Figure 1 and Figure 2, the first one-way communication structure 19 may include a first one-way valve 1903. The first one-way valve 1903 is disposed in the input channel 3. The inlet of the first one-way valve 1903 is adapted to communicate with the first communication port 17, and the outlet of the first one-way valve 1903 is adapted to communicate with the second communication port 18. Optionally, the first one-way valve 1903 may be detachably connected to the following mounting portion 16. Thus, during the process of the pressure in the compression chamber 1 decreasing, the first one-way valve 1903 can connect the first communication port 17 and the second communication port 18, so that the input channel 3 is opened, and thus the medium to be atomized in the storage chamber 2 can be inhaled into the compression chamber 1 through the input channel 3; during the process of the pressure in the compression chamber 1 increasing, the first one-way valve 1903 can cut off the first communication port 17 and the second communication port 18, so that the input channel 3 is closed, and thus the medium to be atomized in the compression chamber 1 will not enter the input channel 3 or the storage chamber 2.

[0078] Optionally, referring to Figure 1 , the extending direction of the input channel 3 is orthogonal to the first direction X, and the compression member 502 is adapted to reciprocate along the first direction X, so that the moving direction of the compression member 502 is perpendicular to the extending direction of the input channel 3, which is beneficial to improving the integration degree of the atomization device.

[0079] It can be understood that the first one-way valve 1903 here and the second one-way valve 2503 appearing below can both adopt the commonly used one-way valve structures in the market. The working principle and specific structure of the one-way valve are well known to those skilled in the art, so they will not be elaborated here.

[0080] The present disclosure does not limit the specific structure of the atomization structure 6. Optionally, as Figure 8 shown, the atomization structure 6 may include an atomization plate 13, and at least one atomization hole 11 is formed on the atomization plate 13. Both ends of the atomization hole 11 communicate with the compression chamber 1 and the mixing chamber 12 respectively. With such a setting, the compression member 502 can press the medium to be atomized from the compression chamber 1 of the atomization device into the output channel 4, and the medium to be atomized in the output channel 4 can be atomized through the atomization hole 11 to form an aerosol and discharged into the mixing chamber 12 for the user to inhale.

[0081] Optionally, the output channel 4 is set as a one-way channel. In the output channel 4, the medium to be atomized is adapted to flow from the compression chamber 1 to the atomization structure 6. Thus, the medium to be atomized in the compression chamber 1 can flow unidirectionally through the output channel 4 to the atomization structure 6, and the medium to be atomized is discharged after being atomized by the atomization structure 6. By setting the output channel 4 as a one-way channel, it is possible to prevent the medium to be atomized from being discharged from the output channel 4 during the process of the compression member 502 sucking the atomizable substance into the compression chamber 1 through the input channel 3.

[0082] It can be understood that, for the convenience of implementing the function that the medium to be atomized in the compression chamber 1 can only flow from the output channel 4 to the atomization structure 6, optionally, in combination with Figure 4 and Figure 5 , the output channel 4 has a third communication port 23 communicating with the compression chamber 1 and a fourth communication port 24 communicating with the atomization structure 6; the atomization device further includes a second one-way communication structure 25, and the second one-way communication structure 25 is adapted to connect or cut off the third communication port 23 and the fourth communication port 24, so as to open or close the output channel 4. With such a setting, during the process of the pressure in the compression chamber 1 decreasing, the second one-way communication structure 25 can cut off the third communication port 23 and the fourth communication port 24, so that the output channel 4 is closed, thereby preventing the compression chamber 1 from communicating with the atomization structure 6; during the process of the pressure in the compression chamber 1 increasing, the second one-way communication structure 25 can connect the first communication port 17 and the second communication port 18, so that the output channel 4 is opened, thereby enabling the medium to be atomized in the compression chamber 1 to be atomized through the output channel 4 and discharged to the outside.

[0083] In the present disclosure, similar to the above-mentioned first one-way communication structure 19, there can be various forms of setting for the second one-way communication structure 25, as long as it can satisfy that when the pressure in the compression chamber 1 decreases, the second one-way communication structure 25 can cut off the third communication port 23 and the fourth communication port 24, and when the pressure in the compression chamber 1 increases, the second one-way communication structure 25 can cut off the third communication port 23 and the fourth communication port 24.

[0084] As an exemplary implementation manner, as shown in Figure 4 and Figure 5 , the second one-way communication structure 25 may include a second mounting member 2501 and a second valve sheet 2502; a second mounting hole 26 is provided on the outlet end face 35 of the mounting portion 16 where the fourth communication port 24 is located, the second valve sheet 2502 is arranged on the outlet end face 35, the second valve sheet 2502 has a second through hole 27 and a second shielding portion 28, and the second shielding portion 28 is used for shielding the fourth communication port 24. That is to say, the second shielding portion 28 can separate the compression chamber 1 and the atomization structure 6. The second mounting member 2501 passes through the second through hole 27 and is inserted into the second mounting hole 26. Here, the second mounting member 2501 can be a plug rod and can be in interference fit with the second mounting hole 26. And, the second shielding portion 28 is arranged to be moved away from the fourth communication port 24 by the medium to be atomized from the compression chamber 1 during the process of the compression member 502 moving in the direction of increasing the pressure in the compression chamber 1.

[0085] Based on the above settings, when the compression member 502 moves in the direction of increasing the pressure in the compression chamber 1, the pressure in the compression chamber 1 increases and the compression member 502 squeezes the medium to be atomized in the compression chamber 1. When the pressure in the compression chamber 1 continues to increase, the second blocking portion 28 can be displaced from the fourth communication port 24 under the extrusion of the medium to be atomized in the compression chamber 1, so that the fourth communication port 24 is exposed, and the medium to be atomized in the compression chamber 1 can be discharged through the fourth communication port 24 and atomized by the atomization structure 6.

[0086] Specifically, in combination with Figure 4 and Figure 5 , the second blocking portion 28 is located outside the output channel 4. The second blocking portion 28 is used to block one side of the fourth communication port 24 and abuts against the outlet end face 35, and the second blocking portion 28 can be a metal sheet or a rubber sheet that can elastically deform. That is to say, when the compression member 502 moves in the direction of increasing the pressure in the compression chamber 1, under the continuous extrusion of the medium to be atomized in the compression chamber 1, the second blocking portion 28 can elastically deform to expose the fourth communication port 24, so that the medium to be atomized can be atomized through the atomization structure 6; when the compression member 502 moves in the direction of decreasing the pressure in the compression chamber 1, the pressure in the compression chamber 1 decreases and a negative pressure can be formed. The second blocking portion 28 abuts against the outlet end face 35 under the external air pressure and returns to its original state, so that the second blocking portion 28 can block the fourth communication port 24 to separate the compression chamber 1 and the atomization structure 6.

[0087] As another exemplary embodiment, in combination with Figure 1 and Figure 2 , the second one-way communication structure 25 includes a second one-way valve 2503. The second one-way valve 2503 is disposed in the output channel 4. The inlet of the second one-way valve 2503 is adapted to communicate with the third communication port 23, and the outlet of the second one-way valve 2503 is adapted to communicate with the fourth communication port 24. Optionally, the second one-way valve 2503 can be detachably connected to the following mounting portion 16. Thus, during the process of the pressure in the compression chamber 1 decreasing, the second one-way valve 2503 can cut off the third communication port 23 and the fourth communication port 24, so that the output channel 4 is closed, so that the compression chamber 1 is not communicated with the atomization structure 6; during the process of the pressure in the compression chamber 1 increasing, the second one-way valve 2503 can communicate the third communication port 23 and the fourth communication port 24, so that the input channel 3 is opened, so that the medium to be atomized in the compression chamber 1 is atomized and discharged through the atomization structure 6.

[0088] Optionally, referring to Figure 1 , the extending direction of the output channel 4 is orthogonal to the first direction X, and the compression member 502 is adapted to reciprocate along the first direction X, so that the moving direction of the compression member 502 is perpendicular to the extending direction of the output channel 4, which is beneficial to improving the integration degree of the atomization device.

[0089] In the present disclosure, in combination with the above-mentioned first communication structure and second communication structure, during the process of the pressure reduction in the compression chamber 1, the first one-way communication structure 19 can communicate the first communication port 17 and the second communication port 18, so that the input channel 3 is opened, and the second one-way communication structure 25 can cut off the third communication port 23 and the fourth communication port 24, so that the output channel 4 is closed, so that the medium to be atomized in the storage chamber 2 can be inhaled into the compression chamber 1 through the input channel 3, and the compression chamber 1 is not communicated with the atomization structure 6; during the process of the pressure increase in the compression chamber 1, the first one-way communication structure 19 can cut off the first communication port 17 and the second communication port 18, so that the input channel 3 is closed, and the second one-way communication structure 25 can communicate the first communication port 17 and the second communication port 18, so that the output channel 4 is opened, so that the medium to be atomized in the compression chamber 1 is atomized and discharged to the outside through the output channel 4, and the medium to be atomized in the compression chamber 1 does not enter the input channel 3 or the storage chamber 2.

[0090] Optionally, as Figure 1 shown, the atomization device further includes an air flow sensor 802, and the air flow sensor 802 is used to monitor the change of the air pressure value of any one or more of the air inlet 9, the air outlet 10 and the gas channel between the air inlet 9 and the air outlet 10. The compression module is adapted to decide whether to atomize the medium to be atomized and output it to the mixing chamber 12 according to the monitoring result of the air flow sensor 802. Thus, when inhaling air from the air outlet 10, the air pressure value of the air outlet 10 will change. Since the air outlet 10 and the air inlet 9 are communicated through the gas channel, the air pressure value of the air inlet 9 and the air pressure value in the air flow channel will also change accordingly. Whether the air flow sensor 802 detects the change of the air pressure value at the air inlet 9, the change of the air pressure value at the air outlet 10 or the change of the air pressure value in the air flow channel, the air flow sensor 802 can detect the same change of the air pressure value.

[0091] The specific monitoring of the change of the air pressure value of any one or more of the air inlet 9, the air outlet 10 and the gas channel by the air flow sensor 802 is determined by the installation position of the air flow sensor 802. As an exemplary implementation manner, the air flow sensor 802 can be installed at a position close to the air inlet 9 to monitor the change of the air pressure at the air inlet 9.

[0092] Here, the air flow channel can be a pipe independently provided in the atomization device for communicating the air inlet 9 and the air outlet 10, or can be the internal space in the atomization device that can communicate the air inlet 9 and the air outlet 10. The present disclosure does not limit this, as long as the air flow channel can communicate the air inlet 9 and the air outlet 10.

[0093] For the convenience of controlling the atomization device, optionally, as Figure 1As shown, the atomizing device further includes a controller 801; the driving mechanism 501 includes a motor 5011 and a transmission assembly 5012, and the motor 5011 is drivingly connected to the compression member 502 through the transmission assembly 5012. The controller 801 is configured to be able to control the motor 5011 to start or stop according to the monitoring result of the airflow sensor 802, so as to connect or disconnect the driving connection between the driving mechanism 501 and the compression member 502.

[0094] Based on this, when inhaling at the air outlet 10, the air pressure values of the air outlet 10, the air inlet 9, and the gas passage will change. The airflow sensor 802 can transmit the detected air pressure value change signal of any one or more of the air inlet 9, the air outlet 10, and the gas passage to the controller 801. At this time, the controller 801 can control the motor 5011 to start, so as to connect the driving connection between the driving mechanism 501 and the compression member 502, so that the compression member 502 can compress the atomization medium to be inhaled into the compression chamber 1, so as to discharge the atomization medium to be atomized through the output channel 4, and the atomization structure 6 can atomize the atomization medium discharged through the output channel 4; when stopping inhaling at the air outlet 10, the air pressure value of the air outlet 10 remains stable. At this time, the air pressure values of the air inlet 9 and the gas passage can also remain stable accordingly. The airflow sensor 802 detects that the air pressure value at the air outlet 10, the air inlet 9, or the gas passage is in a stable state. At this time, the controller 801 can control the motor 5011 to turn off, so as to disconnect the driving connection between the driving mechanism 501 and the compression member 502, and make the compression member 502 stop working.

[0095] It can be understood that, in order to facilitate the power supply of the atomizing device and improve the portability of the atomizing device, optionally, as Figure 1 shown, the atomizing device further includes a power supply unit 7, and the controller 801 is electrically connected to the power supply unit 7. The controller 801 is configured to be able to control the electrical conduction or disconnection between the power supply unit 7 and the motor 5011 according to the monitoring result of the airflow sensor 802, so as to control the motor 5011 to start or stop. Here, the power supply unit 7 can be installed on the atomizing device and integrated with the atomizing device to improve the portability of the atomizing device. Specifically, the power supply unit 7 can be a battery. That is to say, the battery can supply power to the motor 5011, and the controller 801 can control the electrical conduction or disconnection of the circuit between the battery and the motor 5011.

[0096] The present disclosure does not limit the specific type of the airflow sensor 802. Optionally, as Figure 1 and Figure 3 shown, the airflow sensor 802 includes a microphone 8021 and a flexible mounting member 8022 sleeved on the microphone 8021. As Figure 6 and Figure 7As shown in the figure, a receiving groove 14 and an induction hole 34 are provided inside the atomizing device. The microphone 8021 is arranged in the receiving groove 14 through a flexible mounting member 8022. The receiving groove 14 communicates with the outside of the atomizing device through the induction hole 34, and the induction hole 34 is arranged close to the air inlet 9. Thus, the microphone 8021 can be installed in the receiving groove 14 through the flexible mounting member 8022 to form an integral body with the atomizing device. When sucking air at the air outlet 10, the air pressure value at the air inlet 9 can be caused to change. The microphone 8021 can collect the signal of the change in the air pressure value near the air inlet 9 through the induction hole 34, and thus can transmit the signal of the change in the air pressure value to the controller 801.

[0097] In the present disclosure, in addition to the control mode of the air flow sensor 802 plus the controller 801 for the atomizing device, there can be other forms of control modes. As an exemplary implementation, as Figure 4 shown in the figure, the atomizing device further includes a button switch 803. The button switch 803 is adapted to respond to user operations to connect or disconnect the transmission connection between the driving mechanism 501 and the compression member 502. That is to say, the user can directly control the opening and closing of the button switch 803 to achieve the connection or disconnection of the transmission connection between the driving mechanism 501 and the compression member 502.

[0098] Based on the situation that the above atomizing device further includes a power supply unit 7, the button switch 803 can be adapted to respond to user operations to achieve the electrical conduction or disconnection between the power supply unit 7 and the motor 5011, thereby realizing the start or stop of the motor 5011.

[0099] In order to facilitate improving the integration degree of the atomizing device, optionally, as Figure 1 shown in the figure, the atomizing device further includes a housing 32. An accommodation cavity 33, an air inlet 9 and an air outlet 10 are formed inside the housing 32. The atomizing structure 6 is arranged in the accommodation cavity 33 and is located at the air outlet 10. At least a part of the gas passage can be defined between the outer wall of the atomizing structure 6 and the inner wall of the housing 32.

[0100] Optionally, as Figure 1As shown, the atomizing device may further include a mounting portion 16 disposed within the accommodating cavity 33. An output channel 4 is provided on the mounting portion 16 to facilitate the formation of the output channel 4. A convex portion 31 is provided on the mounting portion 16, and the end face where the outlet of the output channel 4 is located is the end face of the convex portion 31 facing the atomizing plate 13. The atomizing structure 6 includes a cylindrical portion 15 and an atomizing plate 13 disposed at one end of the cylindrical portion 15. The cylindrical portion 15 is adapted to be sleeved outside the convex portion 31 of the atomizing device so that the atomizing holes 11 on the atomizing plate 13 can communicate with the cylindrical portion 15. That is to say, the aerosol formed after the medium to be atomized is atomized via the atomizing holes 11 can enter the cylindrical portion 15, facilitating suction by the user. Additionally, grooves 29 are provided on the cylindrical portion 15 and the atomizing plate 13, and at least a part of the gas channel is defined between the grooves 29 and the inner wall of the housing 32.

[0101] To facilitate the suction of the aerosol formed by atomizing the medium to be atomized, optionally, as Figure 1 shown, the housing 32 further has an air suction pipe 30, and the inlet of the air suction pipe 30 communicates with the air outlet 10. The atomizing plate 13 is located within the air suction pipe 30, and the space between the atomizing plate 13 and the outlet of the air suction pipe 30 in the axial direction of the air suction pipe 30 is the mixing chamber 12.

[0102] As an exemplary manner, as Figure 1 shown, the housing includes an upper cover 3201, a middle shell 3202, and a lower cover 3203. Among them, the upper cover 3201, the middle shell 3202, and the lower cover 3203 are sequentially spliced to jointly enclose the above-mentioned accommodating cavity 33. The upper cover 3201 can be detachably connected to the middle shell 3202, and the middle shell 3202 can also be detachably connected to the lower cover 3203. Moreover, the above-mentioned mounting portion 16 and convex portion 31 can be provided within the middle shell 3202, the air suction pipe 30 and the air outlet 10 can be provided on the upper cover 3201, the gas channel can be provided within the middle shell, and the air inlet 9 and the accommodating groove 14 can be provided on the lower cover 3203. Additionally, the lower cover 3203 can also be provided with a space for accommodating the power supply unit 7 to facilitate the installation of the power supply unit 7 and improve the portability of the atomizing device.
