In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "located at," and "located at" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or chemical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0036] As shown in FIG1 to FIG4 , some embodiments of the present application disclose an atomizer 10 , which has an air inlet channel 100 , which is connected to the outside world. The atomizer 10 includes a circuit board 103 , a pneumatic switch 104 , and a bracket 105 , as follows:

[0037] The pneumatic switch 104 is connected to the circuit board 103, with a first gap 106 between them. As shown in Figures 4 and 5 , the bracket 105 is provided with a gas inlet 1051 and a pressure relief outlet 1052, each of which is connected to the air inlet 100. The pneumatic switch 104 is mounted within the bracket 105, separating the gas inlet 1051 from the pressure relief outlet 1052. External gas can enter the gas inlet 1051 from the air inlet 100, while gas within the first gap 106 can be released from the pressure relief outlet 1052 into the air inlet 100.

[0038] Pneumatic switch 104 divides the interior of bracket 105 into a first space and a second space. The first and second spaces are isolated. During suction, the air pressure in the first space at gas inlet 1051 is reduced, and the second space at pressure relief outlet 1052 is connected to the outside atmosphere. This allows detection of the air pressure difference and triggering. For example, pneumatic switch 104 may be a pneumatic sensor, and circuit board 103 may be a PCBA. The pneumatic sensor may be welded or mounted on the PCBA. The pneumatic sensor, PCBA, welding, and mounting are merely examples and are not intended to limit the present application.

[0039] In some embodiments, in order to ensure isolation between the first space and the second space, the bracket 105 is a plastic bracket, and the pneumatic switch 104 can be tightly embedded in the plastic bracket. The plastic bracket here is only an example and is not intended to limit the present application.

[0040] In some embodiments, as shown in FIG4 , the atomizer 10 has an air inlet channel 100, an atomizing chamber 101, and an air outlet channel 102 that are sequentially connected. The user inhales through the suction port of the mouthpiece 112. Air enters the atomizing chamber 101 from the air inlet channel 100 under the action of suction force, mixes with the atomized aerosol in the atomizing chamber 101, and is discharged from the suction port of the mouthpiece 112 after passing through the air outlet channel 102. The airflow direction is shown by the arrow in FIG4 .

[0041] Because the pneumatic switch 104 is not directly exposed in the air inlet channel 100, but is arranged in a narrow branch of the air inlet channel 100, gas is difficult to enter, but the connectivity between the start switch and the air inlet channel 100 is guaranteed, and the air pressure detection is not affected. Therefore, even if the user exhales aerosol during the inhalation process, a small amount of aerosol is exhaled into the pressure relief outlet 1052, which will be buffered by the pressure relief outlet 1052 and the first gap 106 and will not enter the interior of the pneumatic switch 104, thereby avoiding the problem of self-starting and delayed closing of the product during user use.

[0042] If the pneumatic switch 104 is placed tightly against the circuit board 103, and a pressure relief hole is provided on the circuit board 103 at the bottom of the pneumatic switch 104, and the pressure is relieved through the pressure relief hole after the user completes the puffing, the aerosol that is exhaled will be deposited in the pneumatic switch 104 through the pressure relief hole, thereby corroding the diaphragm of the pneumatic switch 104, causing the pneumatic switch 104 to automatically start or close with a delay.

[0043] In some embodiments, as shown in FIG5 , in order to enhance the buffering effect of the pressure relief outlet 1052 on the respired aerosol, the pressure relief outlet 1052 is curved, such as an arc shape or an S shape. The arc shape and S shape here are only examples and are not intended to limit the present application.

[0044] In some embodiments, as shown in FIG11 , the atomizer 10 further includes at least one support member 107 , which is disposed between the pneumatic switch 104 and the circuit board 103 to form a first gap 106 . The height of the first gap 106 ranges from 0.2 to 2 mm, for example, 0.6 mm, 0.8 mm, or 1.2 mm. The 0.6 mm, 0.8 mm, and 1.2 mm values ​​herein are merely examples and are not intended to limit the present application. It is understood that the at least one support member 107 may be one, two, three, or any other number, and the support member 107 may be disposed on the pneumatic switch 104 or on the circuit board 103 .

[0045] For example, the support member 107 is a capacitor, which is arranged on the circuit board 103. The capacitor has no conductive function and utilizes the strength and low cost of the capacitor. The capacitor here is only an example and is not a limitation of this application. It can also be other components that play a supporting role.

[0046] In some embodiments, as shown in Figure 3 or 4, the atomizer 10 further includes a liquid storage tank 108, which is used to store liquid aerosol generating matrix or liquid storage cotton. The bracket 105 is installed on the side of the liquid storage tank 108 facing the circuit board 103. As shown in Figures 7 and 8, an air groove 1081 is provided on the liquid storage tank 108 corresponding to the pressure relief outlet 1052. The gas in the first gap 106 can be decompressed from the pressure relief outlet 1052 and the air groove 1081 to the air inlet channel 100.

[0047] 9 , the side of the circuit board 103 facing the liquid storage tank 108 defines a pressure relief channel 109 together with the pressure relief outlet 1052 and the air passage 1081 . The gas in the first gap 106 can be relieved from the pressure relief channel 109 to the air inlet channel 100 .

[0048] In some embodiments, as shown in FIG10 , a second gap 110 is provided between the circuit board 103 and the inner wall of the liquid storage tank 108 , and the second gap 110 connects the pressure relief channel 109 and the air intake channel 100 , that is, the gas in the first gap 106 can be relieved to the air intake channel 100 through the pressure relief channel 109 and the second gap 110 , and the air flow direction is shown by the arrow in FIG10 .

[0049] In some embodiments, as shown in FIG4 , a gas inlet 1051 is disposed on a side of the bracket 105 facing away from the circuit board 103. An airflow channel 111 is defined between the air inlet channel 100 and the air inlet 1051. The airflow channel 111 is defined by the side of the bracket 105 facing away from the circuit board 103 and the liquid storage tank 108. Within the airflow channel 111, as shown in FIG6 , the bracket 105 is provided with at least one layer of retaining walls 1053. The retaining walls 1053 are used to extend the air intake trajectory from the air inlet channel 100 to the air inlet 1051. It is understood that the at least one layer may be one, two, three, or any number of layers. When at least two layers of retaining walls 1053 are included, they are arranged along the direction from the air inlet channel 100 to the gas inlet 1051. The height of the at least two layers of retaining walls 1053 gradually decreases as they approach the gas inlet 1051. In some embodiments, to further extend the air intake trajectory, the at least two layers of retaining walls 1053 may form a maze. For example, the retaining wall 1053 is arc-shaped and is disposed around the circumference of the gas inlet 1051. The arc shape here is only an example and is not intended to limit the present application.

[0050] In some embodiments, to further extend the gas intake trajectory from the air intake channel 100 to the gas inlet 1051, as shown in FIG4 , the air intake channel 100 includes an air hole 1054 provided on the bracket 105, and the gas inlet 1051 is disposed diagonally opposite the air hole 1054. For example, as shown in FIG6 , a step 1055, such as an annular step, is provided between the air hole 1054 and the gas inlet 1051. The step 1055 is provided on the bracket 105, the air hole 1054 is located on one side of the step 1055, and the gas inlet 1051 is located on the step 1055 and away from the air hole 1054. This results in the gas inlet 1051 being disposed diagonally opposite the air hole 1054, and the direction of the air flow is as shown by the arrow in FIG6 .

[0051] In some embodiments, the liquid reservoir 108 shown in FIG7 is provided with a via 1082, and the circuit board 103 shown in FIG12 is provided with a connection hole 1031 that is directly opposite the via 1082. The external power supply device 20 can be installed in the liquid reservoir 108, and the pin leads 201 of the external power supply device 20 shown in FIG13 are simultaneously passed through the via 1082 and the connection hole 1031, and the diameter of the via 1082 is larger than the diameter of the connection hole 1031. This design reserves a structure on the liquid reservoir 108 and the circuit board 103 that can be switched to fully automated production. The subsequent installation of the capacitor cell can be switched from semi-automatic to fully automated, solving the problem of high manual assembly costs and poor consistency of production personnel. For example, the diameter of the positive and negative electrode pin leads 201 is 0.8 mm, the diameter of the via 1082 is 1.2 mm, the connection hole 1031 is a welding hole, and the diameter of the connection hole is 1 mm. The 0.8 mm, 1.2 mm and 1 mm here are only examples and are not intended to limit this application.

[0052] In some embodiments, as shown in FIG3 , the atomizer 10 further includes a nozzle 112 . A rib structure 1121 is protruded from the surface of the nozzle 112 facing the liquid reservoir 108 . The rib structure 1121 connects to the liquid reservoir 108 , further enhancing the stability of the nozzle 112 assembly and preventing it from accidentally falling and coming loose. Furthermore, the injection port is formed on the rib structure 1121 , resolving the aesthetic issue of having an injection port on the nozzle 112 . Thus, the nozzle 112 can be made of a transparent plastic. For example, the rib structure 1121 includes at least two inserts located on either side of the nozzle 112 .

[0053] As shown in Figures 1 to 3, some embodiments of the present application disclose an electronic atomization device, including a power supply device 20 and an atomizer 10 described in the above embodiment electrically connected to the power supply device 20, which will not be described in detail here. The power supply device 20 can be installed in the electronic atomization device, for example, the power supply device 20 is arranged on one side of the atomization chamber 101, or at one end of the atomization chamber 101. In some embodiments, the power supply device 20 can also be set to be independent of the atomizer 10 and detachably connected to the atomizer 10.

[0054] By implementing this application, the following beneficial effects are achieved:

The pneumatic switch 104 is installed in the bracket 105 and separates the gas inlet 1051 and the pressure relief outlet 1052 on the bracket 105. The external gas can enter the gas inlet 1051 from the air inlet channel 100, and the gas in the first gap 106 can be pressure-relieved from the pressure relief outlet 1052 to the air inlet channel 100, thereby forming an anti-aerosol structure. The back-expelled aerosol will be buffered in the pressure relief outlet 1052 and the first gap 106, and will not directly enter the inside of the pneumatic switch 104, thereby avoiding the problem of self-starting and delayed closing of the product during user use.
