The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0041] like Figure 1 and Figure 3 As shown, an embodiment of the present application provides an atomization device, which includes an atomizer 100 , an airflow sensor 200 and a mounting bracket 300 .

[0042] The nebulizer 100 includes a liquid storage tank 110 and a first sealing member 120. The liquid storage tank 110 is used to store atomized substrates. The liquid storage tank 110 has a first opening 111. One end of the first sealing member 120 is sealed and connected to the first opening 111, so that the atomized substrates stored in the liquid storage tank 110 are sealed by the first sealing member 120 to prevent the atomized substrates in the liquid storage tank 110 from leaking out of the first opening 111, thereby ensuring the stability of the atomized substrates in the liquid storage tank 110. The nebulizer 100 is provided with an atomizing airway 140, which is connected to the vent hole on the first sealing member 120, so that gas can enter the atomizing airway 140 through the vent hole on the first sealing member 120.

[0043] like Figure 2 As shown, in this embodiment, the atomizer 100 also includes a second sealing member 130, and the end of the liquid storage tank 110 facing away from the first sealing member 120 has a second opening 112, and the second sealing member 130 is sealedly connected to the second opening 112, so that the atomized matrix in the liquid storage tank 110 is sealed in the liquid storage tank 110 through the first sealing member 120 and the second sealing member 130, thereby preventing the atomized matrix in the liquid storage tank 110 from leaking from the liquid storage tank 110, thereby ensuring the stability of the atomized matrix in the liquid storage tank 110.

[0044] It should be noted that the vent hole on the first sealing member 120 is misaligned with the first opening 111 of the liquid storage bin 110 to prevent the atomized matrix in the liquid storage bin 110 from leaking out through the vent hole.

[0045] In addition, the atomizer 100 is mounted on the mounting bracket 300, and the connection method between the atomizer 100 and the mounting bracket includes any one of a snap connection, an adhesive connection, a magnetic connection, a threaded connection or a bolt connection.

[0046] Specifically, the mounting frame 300 includes a first surface 310 and a second surface 320 that are arranged opposite to each other, and the other end of the first seal 120 is sealed and connected to the first surface 310, that is, the end of the first seal 120 facing away from the liquid storage tank 110 is sealed and connected to the first surface 310, so as to provide support and limiting effects to the first seal 120 through the mounting frame 300, thereby providing support and limiting effects to the liquid storage tank 110 through the mounting frame 300.

[0047] In this embodiment, the airflow sensor 200 is arranged on the second surface 320. It should be noted that by setting the airflow sensor 200 on the second surface 320, the airflow sensor 200 is protected by the first surface 310 and the second surface 320 of the mounting frame 300 to prevent the condensate refluxed in the atomizing air duct 140 from contacting the airflow sensor 200, thereby ensuring the accuracy of the air pressure detection by the airflow sensor 200 and improving the service life of the airflow sensor 200.

[0048] Furthermore, if Figure 2 and Figure 4 As shown, the mounting frame 300 and the first sealing member 120 cooperate to form a first air duct 400 and a second air duct 500. The first air duct 400 is connected to the atomizing air duct 140, and the gas outside the atomizing device can enter the atomizing air duct 140 through the first air duct 400. The second air duct 500 connects the airflow sensor 200 and the atomizing air duct 140, so that the external gas can flow through the airflow sensor 200 arranged on the second surface 320 through the second air duct 500, and the airflow sensor 200 responds to the change of the air pressure signal to output an electrical signal to the atomizing device, and the electrical signal is received by the atomizing device, thereby controlling the atomizer 100 to start or stop.

[0049] It is understandable that the first seal 120 can not only seal the first opening 111 of the liquid storage tank 110, but also cooperate with the mounting frame 300 to form the first airway 400 and the second airway 500. Since the second airway 500 can communicate with the airflow sensor 200 and the atomizing airway 140, that is, the second airway 500 is a detection airway, so that a part of the gas entering the atomizing device can enter the atomizing airway 140 through the first airway 400, and the tiny liquid in the atomizing airway 140 is discharged from the exhaust port of the atomizing airway 140 along with the airflow. Another part of the gas can flow through the airflow sensor 200 through the second airway 500, and the air pressure change is detected by the airflow sensor 200, so as to output an electrical signal to the atomizing device, and control the start or stop of the atomizer 100 through the atomizing device.

[0050] That is to say, the first seal 120 arranged at the bottom of the liquid storage tank 110 serves as the sealing silicone for the first air duct 400 and the second air duct 500. This eliminates the need to separately provide independent sealing silicone, reduces parts, and can also improve the compactness and simplicity of the atomization device structure, thereby reducing production costs and installation costs.

[0051] like Figure 5 and Figure 6 As shown, in one embodiment, the mounting frame 300 includes a mounting platform 330 and a mounting ring 340, the first surface 310 and the second surface 320 are respectively two opposite sides of the mounting platform 330, and the mounting ring 340 and the mounting platform 330 are integrally formed to ensure the overall strength and stability of the mounting frame 300.

[0052] The mounting ring 340 is disposed on the first surface 310, and the inner wall of the mounting ring 340 and the mounting platform 330 define a first groove 600. It can be understood that the first sealing member 120 and the first surface 310 of the mounting frame 300 define a receiving space, and the receiving space is used to accommodate the liquid absorbing member 900, and the condensed liquid flowing from the atomizing airway 140 into the first groove 600 can be absorbed by the liquid absorbing member 900.

[0053] In addition, the second surface 320 is provided with a second groove 321 , the airflow sensor 200 is accommodated in the second groove 321 , and the second groove 321 is communicated with the first groove 600 .

[0054] Specifically, a through hole connecting the first groove 600 and the second groove 321 is opened at the bottom of the second groove 321, so that the gas entering the first groove 600 can enter the second groove 321 through the second airway 500 and the through hole, thereby enabling the airflow sensor 200 installed in the second groove 321 to detect changes in air pressure.

[0055] like Figure 3 and Figure 5 As shown, in one embodiment, a mounting groove 121 is provided on the side of the first seal 120 facing the mounting frame 300, and the mounting groove 121 is sleeved on the outer side of the mounting ring 340, and the inner wall of the mounting groove 121 abuts against the outer wall of the mounting ring 340 to form a sealing connection structure, which can not only improve the stability of the connection between the first seal 120 and the mounting frame 300, but also avoid the occurrence of gaps at the edge of the connection between the first seal 120 and the mounting frame 300, and prevent the gas entering the first groove 600 from leaking from the edges of the first seal 120 and the mounting frame 300, thereby ensuring the stability of the air pressure during the flow of air between the first seal 120 and the mounting frame 300.

[0056] Among them, a first boss 122 is provided in a part of the bottom area of ​​the mounting groove 121, and the first boss 122 is embedded in the inner side of the mounting ring 340. The outer wall of the first boss 122 abuts against the inner wall of the mounting ring 340 to enhance the stability of the connection between the first seal 120 and the mounting frame 300.

[0057] It should be noted that the outer diameter of the first boss 122 is smaller than the inner diameter of the mounting ring 340 , so that when the first sealing member 120 is sleeved on the mounting ring 340 , the first boss 122 can be partially received in the first groove 600 .

[0058] like Figure 6 As shown, in one embodiment, the outer wall of the mounting ring 340 and the mounting platform 330 define a first step 350, and the periphery of the first seal 120 is protrudingly provided with a second step 123, and the first step 350 abuts against the second step 123, so as to provide support and limiting effects to the first seal 120 through the first step 350, thereby improving the stability of the first seal 120 on the mounting platform 330, thereby ensuring the stability of the connection between the liquid storage tank 110 and the mounting frame 300.

[0059] like Figure 6 and Figure 7 As shown, in one embodiment, the mounting frame 300 further includes a first guide plate 360, a second guide plate 370 and at least one supporting foot 380, wherein the at least one supporting foot 380 is disposed on the second surface 320, wherein an air intake passage 381 is provided through one of the supporting feet 380.

[0060] It is understandable that the number of the supporting feet 380 disposed on the second surface 320 can be one, two, or any number above two, and can be specifically set according to actual conditions.

[0061] It should be noted that, in this embodiment, the number of the supporting feet 380 arranged on the second surface 320 is at least three, and there is a gap between two adjacent supporting feet 380 to define an accommodation space for accommodating the power supply component on the side of the second surface 320 away from the first surface 310.

[0062] Among them, the mounting platform 330 is provided with a connecting port 331 corresponding to the air inlet channel 381, so that the first groove 600 is connected with the air inlet channel 381 through the connecting port 331, so that the gas flowing through the air inlet channel 381 can enter the first groove 600 through the connecting port 331, a part of the gas enters the atomization channel through the first air channel 400, and the other part of the gas enters the second groove 321 through the second air channel 500.

[0063] In addition, the first guide plate 360 ​​and the second guide plate 370 are disposed at intervals, and one end of the first guide plate 360 ​​and the second guide plate 370 is disposed in the first groove 600 .

[0064] Specifically, the other ends of the first guide plate 360 ​​and the second guide plate 370 are abutted against the bottom of the first boss 122, and the first guide plate 360 ​​and the second guide plate 370 form an air guide duct 700, and the air guide duct 700 connects the air inlet channel 381 and the atomizing air duct 140, so as to provide a guiding effect on the gas discharged from the outlet end of the air inlet channel 381 through the air guide duct 700, and guide the gas to the atomizing air duct 140.

[0065] In this embodiment, the air guide passage 700 and the air intake passage 381 are connected to form the first air passage 400 .

[0066] like Figure 6 and Figure 7 As shown, in one embodiment, the opening size of the air guide passage 700 gradually decreases along the side of the air outlet end of the air inlet channel 381 toward the side of the air inlet end of the atomizing air passage 140 .

[0067] It is understandable that by increasing the caliber of the air guide passage 700 on one side close to the outlet end of the air inlet passage 381, the amount of gas entering the air guide passage 700 from the outlet end of the air flow passage is increased. By reducing the caliber of the air guide passage 700 on one side close to the inlet end of the atomizing air passage 140, the gas flow rate from the inlet end of the air guide passage 700 to the outlet end of the air guide passage 700 is increased, thereby increasing the gas flow rate entering the atomizing air passage 140 of the atomizing device.

[0068] In addition, by reducing the caliber of the air inlet end of the air guide airway 700 close to the atomizing airway 140, so that the aperture of the air guide airway 700 close to the air inlet end of the atomizing airway 140 is greater than or equal to the caliber of the air inlet end of the atomizing airway 140, not only the gas flow rate flowing through the atomizing airway 140 can be guaranteed, but also the gas volume flowing through the atomizing airway 140 can be guaranteed. At the same time, the air guide airway 700 can also allow the airflow in the air inlet channel 381 to flow toward the middle position of the atomizing airway 140 of the atomizing device, that is, the air guide airway 700 provides a guiding effect for the gas entering the first groove 600, so that the gas flows along the guide channel toward the air inlet end of the atomizing airway 140 of the atomizing device, so that the airflow in the air guide airway 700 is concentrated to the atomizing airway 140 of the atomizing device, thereby ensuring the gas flow and flow rate entering the atomizing airway 140 of the atomizing device through the air guide airway 700.

[0069] In some embodiments, the first surface 310 is further provided with a baffle 800 , which is disposed in the mounting ring 340 , with both ends of the baffle 800 respectively connected to the inner wall of the mounting ring 340 , and the baffle 800 is disposed around the communication port 331 .

[0070] The first surface 310 is also provided with a baffle 800, and the baffle 800 is arranged in the mounting ring 340. The baffle 800 is connected to the first surface 310, and the two ends of the baffle 800 are respectively connected to the inner wall of the mounting ring 340. The baffle 800 is arranged around the connecting port 331 to provide a barrier effect for the condensate flowing into the guide channel 122a through the baffle 800, so as to prevent the condensate flowing into the guide channel 122a from flowing into the air intake channel 381, so as to protect the air intake channel 381 through the baffle 800.

[0071] The atomizing device further includes a liquid absorbing member 900 . The baffle plate 800 , the mounting ring 340 , the first guide plate 360 ​​, and the second guide plate 370 enclose a receiving space for installing the liquid absorbing member 900 .

[0072] In addition, the atomization device also includes a liquid absorption component 900, and a accommodating space is enclosed between the baffle 800, the mounting ring 340, the first guide plate 360 ​​and the second guide plate 370. The accommodating space is used to install the liquid absorption component 900, so as to absorb the liquid flowing into the first groove 600 through the atomization airway 140 of the atomization device through the liquid absorption component 900, so as to prevent the liquid entering the first groove 600 from flowing into the air inlet channel 381, thereby forming a protective effect on the air inlet channel 381 and a protective effect on the air flow sensor 200 in the second groove 321, so as to ensure the cleanliness of the air inlet channel 381 and the second groove 321.

[0073] It should be noted that the liquid absorbent member 900 can be any one of liquid absorbent cotton and liquid absorbent fiber.

[0074] In some embodiments, the first surface 310 is further provided with a plurality of spacers 1000 , and the plurality of spacers 1000 are staggeredly disposed between the first guide plate 360 ​​and the second guide plate 370 , and form drainage grooves for guiding the flow of the reflowing condensate.

[0075] The number of the spacers 1000 may be two or more than two, and may be set according to actual conditions.

[0076] In this embodiment, the number of the partition bars 1000 is three, and the three partition bars 1000 are arranged at equal intervals along the flow guiding direction of the air guiding passage 700 .

[0077] It can be understood that multiple partitions 1000 are arranged in the air guide duct 700 to limit the air guide duct 700 to form a curved drainage groove, so as to increase the flow path of the returning condensate in the drainage groove, slow down the flow speed of the condensate in the air guide duct 700, and avoid the condensate from flowing into the intake channel 381.

[0078] like Figure 5 and Figure 6 As shown, in one embodiment, a second boss 610 is formed in the first groove 600, and a first through hole 611 is opened in the second boss 610 to connect the first groove 600 and the second groove 321. Since the second boss 610 protrudes from the bottom of the first groove 600, that is, the distance from the top surface of the second boss 610 to the bottom of the first groove 600 is equal to the height of the second boss 610, by arranging the first through hole 611 on the top of the second boss 610, the air inlet end of the first through hole 611 is increased. The distance between the bottom of the first groove 600 and the side wall of the second boss 610 forms a limiting barrier for the condensate flowing into the first groove 600, so as to greatly increase the difficulty of the condensate in the first groove 600 flowing into the first through hole 611, thereby ensuring the cleanliness of the inside of the second mounting groove 121, avoiding the condensate flowing into the first groove 600 from contacting the airflow sensor 200 in the second groove 321, and improving the stability of the airflow sensor 200 arranged in the second mounting groove 121 during operation.

[0079] Among them, a limiting ring 1100 is provided on the side of the second boss 610 away from the second groove 321, and the side of the limiting ring 1100 away from the second boss 610 abuts against the bottom of the mounting groove 121, so as to define a cavity for accommodating liquid absorption between the mounting groove 121, the limiting ring 1100 and the second boss 610, so that the condensed liquid entering into the limiting ring 1100 can be absorbed by the liquid absorption piece 900 arranged in the cavity, so as to prevent the condensed liquid from entering the second groove 321 through the first through hole 611.

[0080] In addition, the side wall of the limiting ring 1100 is provided with a first notch 1110 connected to the first groove 600, and the second groove 321, the first through hole 611, the first notch 1110, the first groove 600 and the atomization airway 140 are connected in sequence, so that the gas flowing through the atomization airway 140 of the atomization device can pass through the first groove 600, the first notch 1110 and the first through hole 611 in sequence and enter the second groove 321, so that the gas can be detected by the airflow sensor 200 installed in the second groove 321.

[0081] like Figure 5 and Figure 8 As shown, in one embodiment, the absorbent member 900 is disposed in the first groove 600 and surrounds the circumference of the second boss 610, and the side wall of the absorbent member 900 is in contact with the side wall of the second boss 610 to enhance the stability of the absorbent member 900 in the first groove 600.

[0082] The first boss 122 is provided with a guide channel 122a, so as to connect the first groove 600 with the atomizing airway 140 through the guide channel 122a. In addition, one end of the liquid absorbing member 900 abuts against the surface of the first boss 122, so as to limit the liquid absorbing member 900 through the first boss 122, so as to further improve the stability of the liquid absorbing member 900 between the mounting frame 300 and the first sealing member 120, and improve the stability of the liquid absorbing member 900 in the first groove 600.

[0083] In this embodiment, the surface of the first boss 122 and the guide channel 122a are combined to form the second air duct 500, and the first boss 122 is spaced from the inner wall of the mounting ring 340 on the side facing the second boss 610 to form an airflow space 1200. The first notch 1110 is arranged toward the airflow space 1200, and the air inlet end of the second air duct 500 is connected with the atomization air duct 140, and the air outlet end of the second air duct 500 is connected with the first notch 1110 through the airflow space 1200, so that the gas flowing through the second air duct 500 can enter the airflow space 1200, flow into the interior of the limit ring 1100 through the first notch 1110, and enter the second groove 321 from the first through hole 611, so that the airflow sensor 200 installed in the second groove 321 can detect the air pressure change.

[0084] like Figure 3 As shown, in one embodiment, the atomization device also includes an atomization assembly 1300 , and the first sealing member 120 is provided with a first guide hole 124 corresponding to the atomization air channel 140 , so that the gas entering the first groove 600 can enter the atomization air channel 140 through the first guide hole 124 .

[0085] Among them, the atomization component 1300 is accommodated in the atomization airway 140, so that the atomization component 1300 can float the tiny droplets formed after the atomization matrix is ​​atomized in the atomization airway 140, and can discharge the tiny droplets in the atomization airway 140 from the exhaust port of the atomization airway 140 along with the gas flowing through the atomization airway 140.

[0086] In addition, one end of the atomizer assembly 1300 is clamped in the first guide hole 124 to provide a limiting effect on the atomizer assembly 1300 through the hole wall of the first guide hole 124, and the inner wall of the first guide hole 124 at least partially protrudes toward the middle of the first guide hole 124 to form a support platform 124a for supporting the atomizer assembly 1300.

[0087] In this embodiment, a portion of the inner wall of the first guide hole 124 protrudes toward the middle of the first guide hole 124 to form a support platform 124 a for supporting the atomizer assembly 1300 , so as to improve the stability of the connection between the atomizer assembly 1300 and the first sealing member 120 .

[0088] like Fig. 9 and Fig.10As shown, an embodiment provides an atomization device, including a power supply device 1400 and the atomization device described in any one of the above embodiments, wherein the power supply device 1400 is arranged on a side of the mounting frame 300 away from the atomizer 100, and the power supply device 1400 is electrically connected to the atomization device and provides electrical energy to improve the stability of the atomization device during operation.
