[0035] This application provides a pneumatic sensor assembly 10, such as... Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the pneumatic sensor assembly 10 is configured for use in an atomizing device, which has a main air passage 101. The pneumatic sensor assembly 10 includes a mounting bracket 110, a seal 120, and a pneumatic sensor 130. The mounting bracket 110 has a first mounting groove 1101 and a first air guide hole 1102, the first air guide hole 1102 connecting the first mounting groove 1101 and the main air passage 101. The seal 120 is embedded in the first mounting groove 1101 and has a second mounting groove 1201 and a second air guide hole 1202 communicating with the second mounting groove 1201. The second air guide hole 1202 and the first air guide hole 1102 form an air passage communication. The groove wall of the first mounting groove 1101 and the seal... A first liquid storage tank 1203 is provided between components 120, and the first liquid storage tank 1203 is at least partially located between the first air guide hole 1102 and the second air guide hole 1202. The first liquid storage tank 1203 is configured to collect condensate flowing from the first air guide hole 1102 to the second air guide hole 1202. A pneumatic sensor 130 is embedded in the second mounting groove 1201. The pneumatic sensor 130 is configured to detect changes in air pressure within the main air passage 101 and output an electrical signal to the atomizing device. During the use or storage of the atomizing device, liquids such as atomizing matrix or condensate may slide down the main air passage 101 and enter the first air guide hole 1102. This application, by providing a first liquid storage tank 1203 between the first air guide hole 1102 and the second air guide hole 1202 to collect liquids such as atomizing matrix or condensate, can effectively prevent liquid from flowing to the second air guide hole 1202, avoid damage to the pneumatic sensor 130 due to contact with liquid, and greatly improve the reliability of the atomizing device.

[0036] In some embodiments, the seal 120 is made of silicone or rubber material with elastic deformation capability.

[0037] In some embodiments, the mounting bracket 110 may be made of rigid plastic or metal.

[0038] In some embodiments, such as Figure 7As shown, the sealing element 120 includes a main body 121 and a first protrusion 122 provided on the main body 121. A second mounting groove 1201 is provided on the side of the main body 121 away from the first protrusion 122. A second air guide hole 1202 is provided on the first protrusion 122. The end of the first protrusion 122 away from the main body 121 abuts against the groove wall of the first mounting groove 1101. The main body 121, the first protrusion 122 and the groove wall of the first mounting groove 1101 surround to form a first liquid storage tank 1203.

[0039] In some embodiments, the first air guide hole 1102 is provided on the bottom wall 113 of the first mounting groove 1101. In some other embodiments, the first air guide hole 1102 may also be provided on the side wall of the first mounting groove 1101.

[0040] In some embodiments, the main body 121 and the sidewall of the first mounting groove 1101 are sealed together, and the first protrusion 122 and the bottom wall 113 of the first mounting groove 1101 are sealed together. The first liquid storage tank 1203 is generally annular in shape and is disposed around the first protrusion 122.

[0041] In some embodiments, the projection plane of the first air guide hole 1102 toward the main body 121 and the projection plane of the second air guide hole 1202 toward the main body 121 do not overlap. The projection plane of the first air guide hole 1102 toward the main body 121 and the projection plane of the first liquid storage tank 1203 toward the main body 121 at least partially overlap, so that the liquid sliding down the first air guide hole 1102 cannot flow directly to the second air guide hole 1202, but flows to the first liquid storage tank 1203.

[0042] In some embodiments, the main body 121 has a connecting surface 125 on the side near the first protrusion 122, the first protrusion 122 is connected to the connecting surface 125, the projection plane of the first air guide hole 1102 toward the plane where the connecting surface 125 is located and the projection plane of the second air guide hole 1202 toward the plane where the connecting surface 125 is located do not coincide, and the first liquid storage tank 1203 is disposed between the connecting surface 125 and the bottom wall 113.

[0043] In some embodiments, the projection surface of the first air vent 1102 toward the main body 121 is located on the outer periphery of the first protrusion 122, and the projection surface of the second air vent 1202 toward the main body 121 is located in the middle of the first protrusion 122.

[0044] In some embodiments, such as Figure 6 As shown, a second protrusion 111 is provided in the first mounting groove 1101. The second protrusion 111 surrounds the first protrusion 122. The connecting surface 125 of the main body 121 abuts against the second protrusion 111. The first liquid storage tank 1203 is located between the first protrusion 122 and the second protrusion 111.

[0045] In some embodiments, the second protrusion 111 is connected between the edge of the bottom wall 113 and the side wall of the first mounting groove 1101.

[0046] In some embodiments, the first protrusion 122 is provided with an air guide groove 1204 at one end away from the main body 121. The air guide groove 1204 is located on the side of the first protrusion 122 away from the first air guide hole 1102. The second air guide hole 1202 is connected to the first liquid storage tank 1203 through the air guide groove 1204. The first liquid storage tank 1203 is connected to the first air guide hole 1102.

[0047] In some embodiments, the sidewall of the second vent 1202 is positioned between the second vent 1202 and the first vent 1102. A vent groove 1204 is formed on the sidewall of the second vent 1202 and extends from the second vent 1202 in a direction away from the first vent 1102, thereby extending the fluid movement path from the first vent 1102 to the second vent 1202. The bottom surface of the vent groove 1204 is closer to the bottom wall 113 than the connecting surface 125 of the main body 121. The liquid level in the first liquid storage tank 1203 must exceed the bottom surface of the vent groove 1204 to pass through the vent groove 1204 and enter the second vent 1202, greatly increasing the difficulty for liquid to enter the second vent 1202.

[0048] In some embodiments, such as Figure 1 , Figure 3 and Figure 6 As shown, the first air guide hole 1102 is located on the bottom wall 113 of the first mounting groove 1101. The projection surface of the main air passage 101 facing the bottom wall 113 of the first mounting groove 1101 does not coincide with the first air guide hole 1102, so that the atomized matrix and condensate and other liquids sliding down the main air passage 101 cannot fall directly into the first air guide hole 1102.

[0049] In some embodiments, the mounting bracket 110 includes a first connecting portion 112, a first mounting groove 1101 and a first air guide hole 1102 disposed on the first connecting portion 112, a second liquid storage tank 1103 disposed on the side of the first connecting portion 112 opposite to the first mounting groove 1101, the first air guide hole 1102 located outside the second liquid storage tank 1103, and a main air passage 101 located on the side of the first connecting portion 112 opposite to the first mounting groove 1101, with at least a portion of the projection surface of the main air passage 101 toward the first connecting portion 112 located within the second liquid storage tank 1103. The second liquid storage tank 1103 can be used to collect liquids such as atomized matrix and condensate that slide down from the main air passage 101, preventing liquids from flowing directly to the first air guide hole 1102.

[0050] In some embodiments, the first connecting portion 112 has a third protrusion 114 on the side near the main air passage 101, and the third protrusion 114 surrounds and forms a second liquid storage tank 1103. The third protrusion 114 is positioned between the second liquid storage tank 1103 and the first air guide hole 1102, and the liquid sliding down the main air passage 101 must fill the second liquid storage tank 1103 before it can pass over the third protrusion 114 and enter the first air guide hole 1102. This application employs two anti-leakage structures—a first liquid storage tank 1203 and a second liquid storage tank 1103—to ensure that any leaked liquid from the main air passage 101 is first stored in the second liquid storage tank 1103. Only then can any overflowing liquid enter the first air guide hole 1102 and be stored in the first liquid storage tank 1203. The liquid level in the first liquid storage tank 1203 must exceed the bottom surface of the air guide tank 1204 before it can pass through the air guide tank 1204 and enter the second air guide hole 1202. This makes it difficult for liquids such as condensate to enter the second mounting slot 1201 through the second air guide hole 1202, thus preventing the pneumatic sensor 130 from contacting the liquid and being damaged.

[0051] In some embodiments, the third protrusion 114 is a rib, which protrudes from the first connecting portion 112 near the main air passage 101. The rib, also known as a reinforcing rib, plays a role in connecting and strengthening the plastic product. The third protrusion 114 can prevent liquid from entering the first air guide hole 1102, and can also strengthen the structural strength of the mounting bracket 110.

[0052] In some embodiments, the mounting bracket 110 further includes a second connecting portion 115 and a third connecting portion 116. The second connecting portion 115 is disposed at one end of the mounting bracket 110 away from the first connecting portion 112, and the third connecting portion 116 is connected between the first connecting portion 112 and the second connecting portion 115. The first connecting portion 112, the second connecting portion 115 and the third connecting portion 116 surround to form a third mounting groove 1104. The third mounting groove 1104 is used to install the battery cell 21, and the second connecting portion 115 is used to connect the atomizing assembly 30. The main air passage 101 is disposed at the second connecting portion 115.

[0053] In some embodiments, the third protrusion 114 is positioned between the first air guide hole 1102 and the third connecting portion 116 to prevent liquids such as atomizing matrix and condensate leaking from the atomizing assembly 30 from flowing from the second connecting portion 115 along the third connecting portion 116 to the first air guide hole 1102 of the first connecting portion 112.

[0054] In some embodiments, such as Figure 2 and Figure 9As shown, the second connecting part 115 has a receiving groove 1107 on the side opposite to the third mounting groove 1104. An air passage 117 is provided in the receiving groove 1107, and the main air passage 101 is provided in the air passage 117. A liquid suction member 150 is installed in the receiving groove 1107. The liquid suction member 150 is arranged around the air passage 117. The liquid suction member 150 is used to absorb liquids such as atomizing matrix and condensate that leak from the atomizing component 30.

[0055] In some embodiments, the absorbent 150 is made of a porous material capable of absorbing liquid. Specifically, the absorbent 150 is absorbent cotton.

[0056] In some embodiments, such as Figure 1 , Figure 7 and Figure 11 As shown, the first connecting part 112 is provided with a third air guide hole 1106, which is connected to the main air passage 101 through a third mounting groove 1104. The sealing member 120 is provided with an air guide part 124, which is provided with a fourth air guide hole 1205, which is used to connect the third air guide hole 1106 to the outside. A sealing plug 22 is inserted into the fourth air guide hole 1205, and the sealing plug 22 and the air guide part 124 are detachably connected. The sealing plug 22 is configured to be inserted into the fourth air guide hole 1205 and seal the fourth air guide hole 1205. When the user uses the atomizing device, the sealing plug 22 can be pulled out, and the outside airflow can enter the third mounting groove 1104 along the fourth air guide hole 1205 and the third air guide hole 1106, and then enter the main air passage 101 through the third mounting groove 1104.

[0057] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the pneumatic sensor assembly 10 also includes a circuit board 140, located at the end of the seal 120 away from the first air guide hole 1102. The pneumatic sensor 130 is mounted on the circuit board 140. A sealing portion 123 protrudes from the wall of the second mounting groove 1201, surrounding the pneumatic sensor 130 and forming an interference fit between the sealing portion 123 and the pneumatic sensor 130. The sealing portion 123 improves the sealing connection between the pneumatic sensor 130 and the seal 120, preventing fluid leakage from the gap between the pneumatic sensor 130 and the seal 120, thus improving the sensitivity of the pneumatic sensor 130. Simultaneously, it prevents further leakage of condensate into the circuit board 140, which could cause a short circuit, thereby improving the safety of the atomizing device.

[0058] This application embodiment also provides a power supply component 20, such as Figure 8 and Figure 9As shown, the power supply assembly 20 includes the pneumatic sensor assembly 10 of the above embodiment, and the power supply assembly 20 also includes a battery cell 21, which is mounted in the third mounting slot 1104 of the mounting bracket 110.

[0059] This application also provides an atomizing device, such as... Figure 10 and Figure 11 As shown, the atomizing device includes the power supply component 20 of the above embodiment, and the atomizing device also includes the atomizing component 30. The power supply component 20 and the atomizing component 30 are electrically connected to supply power to the atomizing component 30.

[0060] In some embodiments, the atomizing assembly 30 includes an atomizing core 31 and a mouthpiece 32. The atomizing core 31 is provided with an atomizing channel, and the main air passage 101 is connected to the mouthpiece 32 through the atomizing channel.

[0061] In some embodiments, the atomizing assembly 30 further includes a liquid storage chamber, an atomizing core 31 disposed within the liquid storage chamber, the atomizing core 31 including an atomizing tube, a liquid storage component between the atomizing tube and the liquid storage chamber, the liquid storage component for storing the atomizing matrix, a heating element and a liquid guiding element disposed within the atomizing tube, the liquid guiding element wrapping around the heating element, the liquid guiding element being connected to the liquid storage component through a through hole in the atomizing tube to guide the atomizing matrix in the liquid storage component to the heating element, where the atomizing matrix is ​​heated and atomized by the heating element to form an aerosol. The liquid guiding element can be oil-wicking cotton; the heating element can be a heating wire or heating mesh made of materials such as iron-chromium-aluminum, stainless steel, or nickel-chromium alloy; the liquid storage component can be oil-absorbing cotton, the material of which can include flax cotton and oil-impregnated cotton.

[0062] In some embodiments, the atomizing component 30 is at least partially inserted into the receiving groove 1107, and the atomizing channel is connected to the main air passage 101 through the receiving groove 1107. The projection planes of the main air passage 101 and the atomizing channel on a plane perpendicular to the axial direction of the main air passage 101 do not coincide, so that liquids such as atomizing matrix and condensate leaking from the atomizing channel will not fall directly into the main air passage 101, but will fall into the liquid suction member 150 in the receiving groove 1107 and be absorbed by the liquid suction member 150.

[0063] In some embodiments, the atomizing device includes a housing 40 and a bottom cover 50, with a power supply assembly 20 and an atomizing assembly 30 mounted on the housing 40. The nozzle 32 and the bottom cover 50 are respectively connected to both ends of the housing 40.

[0064] In some embodiments, the bottom cover 50 is provided with an air inlet, and the sealing plug 22 is used to block the air inlet. When using the atomizing device, the user can remove the sealing plug 22 to connect the pneumatic sensor 130 with the air inlet and to connect the fourth air guide hole 1205 with the air inlet.

[0065] The pneumatic sensor assembly 10, power supply assembly 20, and atomizing device provided in this application are characterized by a two-layer liquid storage structure consisting of a first liquid storage tank 1203 and a second liquid storage tank 1103. This structure effectively intercepts liquids such as atomizing matrix and condensate that leak from the atomizing assembly 30, preventing condensate and other liquids from leaking into the pneumatic sensor 130 and circuit board 140, thereby improving the reliability and service life of the atomizing device.

[0066] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
