[0037] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features.

[0039] In this application, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] In the related art, the pins of the heating wire are connected to the PCB circuit board below by welding. When the oil tank leaks or condensation is generated in the oil tank, the liquid in the oil tank will drip along the pins to the PCB circuit board, causing a short circuit.

[0041] In response to the above problems, Figure 1 , Figure 3 and Figure 5As shown, the embodiment of the present application provides an atomization device 100, including an atomizer 110 and a power supply assembly 120. The power supply assembly 120 is used to provide electrical energy to the atomizer 110, so that the atomizer 110 works to generate aerosol.

[0042] In some embodiments, the atomizer 110 includes a housing 111 and a heating element 113. A liquid storage chamber 114 is formed inside the housing 111, and the liquid storage chamber 114 stores the aerosol matrix.

[0043] The heating element 113 is received in the liquid storage cavity 114 , and is used to heat the aerosol matrix in the liquid storage cavity 114 to generate aerosol.

[0044] The heating element 113 has at least two leads (not shown). A first hollow cylinder 11111 connected to the liquid storage chamber 114 is protruded from the bottom outer surface of the shell 111. At least two leads are passed through the first hollow cylinder 11111 and are led out from the liquid storage chamber 114 to be electrically connected to the power supply component 120.

[0045] The power supply component 120 includes a circuit board 121, which has a first through hole 1211. The circuit board 121 is disposed at the bottom of the shell 111, and a first hollow cylinder 11111 is passed through the first through hole 1211, so that a port of the first hollow cylinder 11111 is separated from the circuit board 121. In this way, liquid flowing into the first hollow cylinder 11111 along the lead will not contact the circuit board 121, thereby protecting the circuit board 121 and extending the service life of the atomization device 100.

[0046] The above-mentioned separation state means that the end of the first hollow cylinder 11111 away from the shell 111 is staggered from the solid part of the circuit board 121, so that the first hollow cylinder 11111 is aligned with the first through hole 1211, for example, flush with the side of the circuit board 121 away from the shell 111, or, the end of the first hollow cylinder 11111 away from the shell 111 exceeds the side of the circuit board 121 away from the shell 111.

[0047] At least two lead seals are inserted into the first hollow cylinder 11111 and are electrically connected to the circuit board 121 , so that the liquid in the liquid storage chamber 114 that flows into the first hollow cylinder 11111 along the lead cannot flow out of the first hollow cylinder 11111 , thereby improving the leakage of the atomization device 100 .

[0048] In some embodiments, Figure 2 and Figure 3 As shown, the atomization device 100 further includes a first liquid absorbing member 150 and / or a colloid (not shown).

[0049] In some embodiments, the atomizing device 100 includes a first liquid absorbing member 150, which is disposed on a side of the circuit board 121 away from the housing 111, and a port of the first hollow cylinder 11111 faces the first liquid absorbing member 150. The liquid in the liquid storage chamber 114 that flows into the first hollow cylinder 11111 along the lead wire is absorbed by the first liquid absorbing member 150, and the liquid does not contact the circuit board 121, thereby protecting the circuit board 121 and extending the service life of the atomizing device 100.

[0050] In some embodiments, the first liquid absorbent member 150 is made of absorbent cotton, which can quickly absorb the liquid flowing out along the lead wire. The absorbent cotton can also simplify the structure of the first liquid absorbent member 150 and reduce the space occupied by the first liquid absorbent member 150, making the structure of the atomizing device 100 more compact and smaller.

[0051] In some embodiments, the atomization device 100 includes a colloid, which is filled in the first hollow cylinder 11111 and completely closes the gap between the inner wall of the first hollow cylinder 11111 and the lead. After the lead passes through the first hollow cylinder 11111, glue is dispensed in the first hollow cylinder 11111 to fix the lead, and the dispensed glue forms a colloid after solidification.

[0052] By providing the colloid, the first hollow cylinder 11111 is changed from a conducting state to a closed state, and the liquid in the liquid storage chamber 114 that flows into the first hollow cylinder 11111 along the lead wire cannot flow out of the first hollow cylinder 11111, thereby improving the leakage of the atomization device 100.

[0053] Of course, in some embodiments, the colloid can be replaced by a silicone part or a plastic part. A through hole is provided on the silicone part or the plastic part for the lead to pass through, and the connection between the silicone part or the plastic part and the lead, and the connection between the silicone part or the plastic part and the first hollow cylinder 11111 are sealed to improve the leakage of the atomizing device 100.

[0054] In some embodiments, the atomization device 100 includes a first liquid absorbing member 150 and a colloid, and the colloid blocks the first hollow cylinder 11111 to improve the leakage. When the lead or the colloid is loose or moves, there is a situation where liquid leaks from the first hollow cylinder 11111. The first liquid absorbing member 150 is also provided to absorb the liquid leaked from the first hollow cylinder 11111, forming a double anti-leakage structure.

[0055] In one embodiment, the heating element 113 includes a mesh heating wire 1131, one lead is connected to the cathode of the heating wire 1131, and the other lead is connected to the anode of the heating wire 1131. In this way, the two leads are electrically connected to the power supply assembly 120, so that the temperature of the heating wire 1131 is increased, and the aerosol matrix in the liquid storage chamber 114 is heated. It can be understood that in other embodiments, the heating element 113 can also be a spiral heating wire, or a ceramic heating element, etc.

[0056] like Figure 6 As shown, the cross section of the first hollow cylinder 11111 is roughly in the shape of an "8". The first hollow cylinder 11111 has two independent small conduction chambers 11113, and a lead is inserted into a small conduction chamber 11113, which is conducive to separate and fix the two leads and mark the positions of the two leads. For example, the anode lead is inserted into the upper small conduction chamber 11113, and the cathode lead is inserted into the lower small conduction chamber 11113. When setting the colloid, it is necessary to dispense glue to the two small conduction chambers 11113. Of course, the two small conduction chambers 11113 can also be combined into a large conduction chamber, and the anode and cathode are distinguished according to the colors of the two leads, and only one dispensing operation is required.

[0057] In some embodiments, Figure 8 As shown, a plurality of solder pads 1214 are disposed at intervals on one side of the circuit board 121 away from the housing 111 , and the end of each lead is soldered to a corresponding solder pad 1214 .

[0058] Two recessed areas 11114 are provided at the end of the first hollow cylinder 11111 away from the bottom plate 1111, and a soldering pad 1214 is provided at one recessed area 11114. In this way, the end of each lead passes through the first hollow cylinder 11111 and is bent and clamped in the recessed area 11114, thereby avoiding the entanglement of multiple leads and aligning the end of the lead with the soldering pad 1214, thereby improving the subsequent welding efficiency and the bonding stability of the welding structure.

[0059] In some embodiments, Figure 2 and Figure 6 As shown, the atomizer 100 also includes a battery 160 and a display element 170 electrically connected to the circuit board 121. The outer peripheral surface of the shell 111 has a support plate 1113 extending away from the liquid storage chamber 114. The battery 160 is fitted with the outer side surface of the shell 111. The battery 160 is arranged on the support plate 1113, so that the battery 160 and the shell 111 are arranged side by side, thereby reducing the volume of the atomizer 100.

[0060] In some embodiments, the display element 170 is disposed on the support plate 1113 to reduce the volume of the atomization device 100 .

[0061] like Figure 5 and Figure 8 As shown, two solder joints 1215 are spaced apart on the side of the circuit board 121 away from the base plate 1111. The end electrode of the battery 160 away from the support plate 1113 is electrically connected to one of the solder joints 1215 via a lead wire, and the end electrode of the battery 160 close to the support plate 1113 is electrically connected to the other solder joint 1215 via a lead wire.

[0062] In some embodiments, Figures 3 to 5 As shown, the atomization device 100 further includes a liquid collecting member 180 . The liquid collecting member 180 is disposed below the housing 111 . The liquid collecting member 180 is used to collect liquid leaked from the liquid storage chamber 114 .

[0063] In some embodiments, an atomization channel 1121 is formed in the shell 111, and a third hollow cylinder 11112 connected to the liquid storage chamber 114 is protruded from the inner surface of the bottom of the shell 111, and a sealed partition is formed between the third hollow cylinder 11112 and the second hollow cylinder 184, and the third hollow cylinder 11112 is inserted in the atomization channel 1121.

[0064] In some embodiments, the third hollow cylinder 11112 and the channel wall of the atomization channel 1121 are sealed and connected, so that part of the liquid in the atomization channel 1121 flows into the third hollow cylinder 11112 along the channel wall of the atomization channel 1121, and the rest of the liquid flows into the first hollow cylinder 11111 along the lead.

[0065] In some embodiments, a second hollow cylinder 184 is convexly provided on a side of the liquid collecting member 180 facing away from the housing 111, and the first hollow cylinder 11111 is spaced apart from the second hollow cylinder 184. A second through hole 1212 is formed on the circuit board 121 and spaced apart from the first through hole 1211. The second hollow cylinder 184 is connected to the atomization channel 1121 and is penetrated through the second through hole 1212. In this way, when the liquid leaked from the liquid storage chamber 114 flows into the second hollow cylinder 184, part of the liquid is retained in the columnar second hollow cylinder 184, which can reduce liquid leakage.

[0066] The second hollow cylinder 184 includes a large-diameter hollow cylinder and a small-diameter hollow cylinder that are integrally arranged. The large-diameter hollow cylinder is arranged on the side of the liquid collecting member 180 away from the circuit board 121, so that the end surface of the large-diameter cylinder is higher than the surface of the liquid collecting member 180, thereby reducing the liquid collected in the liquid collecting member 180 from leaking out of the second hollow cylinder 184. The small-diameter hollow cylinder is inserted into the second through hole 1212 to guide the air in the second through hole 1212 into the second hollow cylinder 184.

[0067] In one embodiment, Figure 6As shown, a leak-proof structure 1841 is provided at the end of the second hollow cylinder 184 close to the circuit board 121 . The leak-proof structure 1841 does not affect the gas entering the second hollow cylinder 184 , and can also reduce the condensate flowing out of the second hollow cylinder 184 .

[0068] In some embodiments, the leakage-proof structure 1841 is a grid-like or film-like structure.

[0069] In some embodiments, Figure 2 and Figure 3 As shown, the heating element 113 is disposed in the atomizing channel 1121. The heating element 113 also includes an atomizing tube 1132 located in the atomizing channel 1121. The atomizing tube 1132 is a hollow structure and is spaced apart from the third hollow cylinder 11112. The heating wire 1131 is accommodated in the atomizing tube 1132.

[0070] A hole 11321 is formed on the side wall 181 of the atomizing tube 1132 . The lead wire passes through the hole 11321 of the atomizing tube 1132 , the atomizing channel 1121 and the third hollow cylinder 11112 in sequence. The lead wire is located outside the third hollow cylinder 11112 .

[0071] The axial direction of the first hollow cylinder 11111 , the axial direction of the second hollow cylinder 184 , and the axial direction of the third hollow cylinder 11112 are respectively parallel to the atomization channel 1121 .

[0072] In some embodiments, the bottom of the housing 111 is recessed to form a receiving cavity 115. Figure 2 and Figure 3 As shown, the housing 111 further includes a panel 1112 and a bottom plate 1111. The panel 1112 is roughly in the shape of a hollow square column, the bottom plate 1111 is received in the panel 1112, connected to the inner side of the panel 1112, and the inner space of the panel 1112 is divided into a liquid storage chamber 114 and a receiving chamber 115, the power supply assembly 120 is arranged corresponding to the receiving chamber 115, and the first hollow cylinder 11111 and the third hollow cylinder 11112 are respectively arranged on the bottom plate 1111.

[0073] The liquid collecting member 180 is disposed in the receiving chamber 115 . The liquid collecting member 180 is spaced apart from the bottom of the receiving chamber 115 to form an air guiding channel 183 . The air guiding channel 183 is connected to the atomizing channel 1121 and the second hollow cylinder 184 .

[0074] In some embodiments, Figure 4 , Figure 5 and Figure 7 As shown, the liquid collecting member 180 includes a side wall 181 and a bottom wall 182 .

[0075] The side wall 181 is arranged around the outer periphery of the bottom wall 182, and the side wall 181 and the bottom wall 182 are spaced apart from the bottom plate 1111 to form an air guide channel 183. The air guide channel 183 connects the atomization channel 1121 and the second hollow cylinder 184, and the air guide channel 183 also connects the third hollow cylinder 11112.

[0076] The side wall 181 is disposed between the bottom plate 1111 and the circuit board 121 , and is engaged with the outer side surface of the first hollow cylinder 11111 .

[0077] like Figure 6 As shown, a convex portion is formed on the side wall 181, and a concave portion is correspondingly formed on the outer side of the first hollow cylinder 11111. The convex portion and the concave portion cooperate to form a snap connection between the liquid collecting member 180 and the first hollow cylinder 11111, thereby improving assembly efficiency. Of course, the convex portion and the concave portion can also be exchanged to form a snap connection between the liquid collecting member 180 and the first hollow cylinder 11111; a rubber block with elastic force can also be provided to cooperate with the groove so that the rubber block is squeezed into the groove to form a snap connection.

[0078] In some embodiments, Figure 4 As shown, the side of the liquid collecting part 180 facing away from the shell 111 is recessed to form a receiving groove 185, and the power supply component 120 also includes a pneumatic switch 122, which is connected to the side of the circuit board 121 close to the shell 111 and is arranged in the receiving groove 185. A third through hole 1851 is opened on the groove body of the receiving groove 185 facing away from the circuit board 121, and the third through hole 1851 connects the air guide channel 183 and the atomization channel 1121.

[0079] like Figure 3 and Figure 6 As shown, the third through hole 1851 is arranged on the side of the receiving groove 185 away from the third hollow cylinder 11112, so that the leaked liquid will not flow to the pneumatic switch 122 through the third through hole 1851, thereby protecting the pneumatic switch 122 and preventing the liquid from flowing onto the circuit board 121, thereby protecting the circuit board 121 under the receiving groove 185.

[0080] In some embodiments, the side wall 181 , the bottom wall 182 and the receiving tank 185 enclose a liquid collection area 186 . The liquid collection area 186 is disposed at the bottom of the third hollow cylinder 11112 to collect liquid flowing out of the third hollow cylinder 11112 .

[0081] like Figure 3 and Figure 4 As shown, in a direction perpendicular to the axial direction of the atomizing channel 1121 , the second hollow cylinder 184 and the receiving groove 185 are spaced apart from the atomizing channel 1121 , so that the liquid is not easy to flow onto the second hollow cylinder 184 and the receiving groove 185 .

[0082] In some embodiments, Figure 4 As shown, the circuit board 121 is further provided with a fifth through hole 1213 disposed below the pneumatic switch 122, and the fifth through hole 1213 is communicated with the receiving groove 185. The atomizing device 100 further includes a housing 140, in which the atomizer 110 and the power supply assembly 120 are both accommodated, and a fourth through hole 144 communicating with the outside is provided at the bottom of the housing 140, the circuit board 121 and the bottom of the housing 140 are spaced apart, and the fifth through hole 1213 is communicated with the fourth through hole 144.

[0083] The pneumatic switch 122 is electrically connected to the power supply assembly 120 and is used to control the start and stop state of the heating element 113. The pneumatic switch 122 has a sensing membrane for sensing air pressure difference.

[0084] The fifth through hole 1213 and the air guide channel 183 are respectively arranged on opposite sides of the sensing film of the pneumatic switch 122. When the user inhales at the mouthpiece, negative pressure is provided in the air guide channel 183. Since the fifth through hole 1213 is connected to the fourth through hole 144 on the housing 140, the diameter of the fifth through hole 1213 is small, and the ventilation volume is small, so that the fifth through hole 1213 is used to provide atmospheric pressure under normal pressure.

[0085] Under the action of negative pressure and normal pressure, a pressure difference is formed on the opposite sides of the sensing film of the pneumatic switch 122, and the sensing film of the pneumatic switch 122 bulges toward the air guide channel 183. The pneumatic switch 122 is activated to heat the heating element 113 and generate aerosol.

[0086] When the user stops inhaling, the negative pressure in the air guide channel 183 changes to normal pressure, the pressure difference formed on the opposite sides of the sensing membrane of the pneumatic switch 122 disappears, the sensing membrane of the pneumatic switch 122 returns to being flat, the pneumatic switch 122 is closed, and the heating element 113 stops heating.

[0087] In one embodiment, Figure 2 As shown, the first liquid absorbent member 150 is also provided with an avoidance portion 152, and the liquid absorbent cotton of the avoidance portion 152 is spaced apart from the second through hole 1212 and the fifth through hole 1213 on the circuit board 121, so that the second through hole 1212 and the fifth through hole 1213 on the circuit board 121 are not blocked, thereby improving ventilation efficiency.

[0088] In one embodiment, Figure 2 As shown, a power supply socket 123 is further formed on one side of the circuit board 121 away from the bottom plate 1111 , a sixth through hole 151 is formed on the first liquid absorbent member 150 , and the power supply socket 123 is penetrated through the sixth through hole 151 to position the first liquid absorbent member 150 .

[0089] like Figure 3As shown, the housing 140 includes a first shell 142 and a second shell 143 . The first shell 142 is sleeved on the outside of the second shell 143 . The atomizer 110 , the power supply assembly 120 and the cover assembly 131 are all accommodated in the second shell 143 .

[0090] In some embodiments, Figure 2 and Figure 3 As shown, the atomizer 100 also includes a nozzle assembly 130 and a liquid storage part 112. The nozzle assembly 130 is arranged on the top of the atomizer 110. The nozzle assembly 130 includes a cover assembly 131 and a nozzle part 132 arranged in sequence. The cover assembly 131 encloses the heating element 113 in the shell 111 and is spaced apart from the liquid storage part 112.

[0091] In some embodiments, the liquid storage member 112 includes a liquid storage element and an aerosol matrix. The liquid storage element absorbs the aerosol matrix by capillary absorption, so that the aerosol matrix is ​​stored in the liquid storage element.

[0092] like Figure 2 As shown, the cover assembly 131 includes an upper cover 1311, a lower cover 1313, and a second liquid absorbing member 1312 accommodated between the upper cover 1311 and the lower cover 1313. A first channel 1315 is formed in the cover assembly 131, which passes through the upper cover 1311, the lower cover 1313, and the second liquid absorbing member 1312, and the first channel 1315 is connected to the atomization channel 1121.

[0093] The upper cover 1311 is connected to the suction nozzle 132 , and includes a first portion 13111 disposed at the end of the liquid storage member 112 and a second portion 13112 disposed at the end of the battery 160 . The first portion 13111 is sealed to the end of the enclosure 1112 .

[0094] In addition, the upper cover 1311 is a non-light-transmitting structure, which plays a light-shielding role and prevents the aerosol matrix from volatilizing after being irradiated by light.

[0095] The second liquid absorbent member 1312 is disposed between the first portion 13111 and the lower cover 1313 . The lower cover 1313 and the second liquid absorbent member 1312 are both contained in the enclosure 1112 . The second liquid absorbent member 1312 is used for absorbing the aerosol matrix leaving the liquid storage element.

[0096] The lower cover 1313 and the liquid storage element 112 are spaced apart, so that space can be reserved for the liquid storage element to expand due to heat, thereby reducing the situation where the liquid storage element is squeezed by the lower cover 1313 and the aerosol matrix is ​​squeezed out of the liquid storage element, thereby reducing liquid leakage of the atomization device 100.

[0097] In some embodiments, the upper cover 1311 and the lower cover 1313 are both made of plastic.

[0098] In some embodiments, a protrusion structure 1314 is formed at the end of the cover assembly 131 close to the liquid storage element 112 to limit the liquid storage element 112 from approaching the cover assembly 131. When the liquid storage element expands due to heat, the protrusion structure 1314 is embedded in the liquid storage element to limit the liquid storage element.

[0099] A second channel 1321 is formed in the nozzle member 132, and the second channel 1321 is connected to the first channel 1315. The nozzle member 132 closes the opening 141 of the housing 140. The fourth through hole 144 of the housing 140 is a stacked hole provided on the first shell 142 and the second shell 143. The fourth through hole 144 connects the second through hole 1212 on the circuit board 121 with the outside air.

[0100] When the user inhales at the mouthpiece 132, the airflow direction in the atomizer 100 is as follows: external air enters the housing 140 from the fourth through hole 144, enters the second hollow cylinder 184 through the second through hole 1212 of the circuit board 121, enters the first hollow cylinder 11111 through the air guide channel 183, and reaches the user's mouth through the atomization channel 1121, the first channel 1315 and the second channel 1321.
