[0042] Figures 1 to 3 An electronic atomizing device according to some embodiments of the present invention is shown, which may include an atomizer 1 and a main unit 2. The main unit 2 can supply power to the atomizer 1 and control the operation of the entire electronic atomizing device. The atomizer 1 is used to heat and atomize a liquid aerosol generating matrix to form an aerosol after being powered on, and then inhale it for the user. In this embodiment, the electronic atomizing device is generally rectangular in shape. It is understood that in other embodiments, the electronic atomizing device is not limited to being rectangular in shape, and may also be cylindrical, elliptical, flat, or other shapes.

[0043] In some embodiments, the main unit 2 may include a rectangular cylindrical housing 21, a second support 22, a battery 23, and a power assembly 24. The housing 21 houses the second support 22, the battery 23, and the power assembly 24. The second support 22 mounts the battery 23 and the power assembly 24. The battery 23 is electrically connected to a pair of electrode posts 135 of the atomizer 1, thereby supplying power to the atomizer 1 and controlling the operation of the entire electronic atomizing device. The power assembly 24 provides fluid power, thereby supplying liquid from the liquid storage assembly 12 of the atomizer 1 to the liquid delivery channel 1311. The fluid power can be liquid-based or gas-based; in this embodiment, the fluid power is gas-based.

[0044] In some embodiments, the power component 24 may be a peristaltic pump. This power component 24 is connected to the liquid storage component 12 via the pumping pipe 15 of the atomizer 1, providing power to compress the soft capsule 123 in the liquid storage shell 122, thereby driving the liquid aerosol generation matrix in the soft capsule 123 from the liquid outlet 1212 to the atomizing component 13. The power component 24 can start or stop the liquid supply based on the detection result of the liquid level detection component 14.

[0045] In some embodiments, the power assembly 24 may include a pump body 241, a hose 242 surrounding the pump body 241, and a second connector 243. The pump body 241 provides frictional force to cause the hose 242 to peristalse, thereby delivering gas. The hose 242 delivers outside air into the reservoir 122. The second connector 243 connects the hose 242 to the air pumping conduit 15. In some embodiments, the hose 242 includes a second air inlet 2421 at one end in contact with outside air and a second air outlet at the other end connected to the second connector 243. When the power assembly 24 is operating, outside air is transmitted through the second air inlet 2421 to the second air outlet, and the second air outlet transmits the air through the air pumping conduit 15 into the reservoir 122, thereby compressing the soft bladder 123.

[0046] like Figure 3 and Figure 4As shown, in some embodiments, the atomizer 1 may be rectangular in shape and may include a mouthpiece assembly 11, a liquid storage assembly 12, an atomizing assembly 13, a liquid level detection assembly 14, and a pumping conduit 15.

The depletion of the liquid aerosol generating matrix in the infusion channel 1311 means that the liquid aerosol generating matrix is ​​no longer usable by the atomizer 1 or that there is a liquid aerosol generating matrix film attached to the surface of the infusion channel 1311 and the liquid level detection assembly 14.

[0047] In some embodiments, the mouthpiece assembly 11 includes a housing 111 sleeved on the atomizing assembly 13 and an airflow channel 113 connected to the airflow channel of the atomizing assembly 13. The upper end of the housing 111 forms a reduced mouthpiece, and the middle of the mouthpiece has a third air outlet 112. The airflow channel 113 is connected to the third air outlet 112.

[0048] In some embodiments, the housing 111 includes a first receiving space 1111 located at the upper end of the housing, a second receiving space 1112 located at the lower end of the first receiving space 1111, and a third receiving space 1113 located at the lower end of the first receiving space 1111 and adjacent to the second receiving space 1112.

[0049] like Figure 8 and Figure 9 As shown, in some embodiments, the liquid storage assembly 12 may include a bottom cover 121, a rectangular cylindrical liquid storage shell 122 mounted on the bottom cover 121, and a soft capsule 123. The bottom cover 121 is used to seal the soft capsule 123. In some embodiments, the liquid storage shell 122 may be made of a rigid material and is used to contain the soft capsule 123. In some embodiments, the soft capsule 123 is made of a soft material and is used to store the liquid aerosol generation matrix.

[0050] In some embodiments, the bottom cover 121 may include a third air inlet 1211, a liquid outlet 1212, a square peripheral wall 1213 extending from the upper surface of the bottom cover, and a first receiving groove 1214. The third air inlet 1211 corresponds to the second connecting hole 1115 and is connected to the air pump pipe 15, allowing outside air to be transmitted into the liquid storage shell 122, thereby compressing the soft capsule 123 inside the liquid storage shell 122. The liquid outlet 1212 corresponds to the first connecting hole 1114 and is connected to the liquid inlet 1317 of the atomizing component 13, used to transfer the liquid aerosol generating matrix into the atomizing component 13, realizing the liquid-guiding communication between the liquid storage component 12 and the atomizing component 13. The peripheral wall 1213 surrounds the liquid outlet 1212 and is used to guide the liquid aerosol generating matrix in the soft capsule 123 to flow to the atomizing component 13. The first receiving groove 1214 is connected to the third air inlet 1211 and is used to receive the upper pipe section 1552 of the pump air pipe 15. The bottom cover 121 also includes a soft sealing element 1215 disposed in the liquid outlet 1212, which is used to seal the soft bag 123.

[0051] See also Figures 10 to 13 In some embodiments, the atomizing assembly 13 includes a first atomizing seat 131, a second atomizing seat 132 disposed on one side of the first atomizing seat 131 and connected to the first atomizing seat 131, a first porous body 133 disposed between the first detection electrode 141 and the second detection electrode of the liquid level detection assembly 14, an atomizing core 134 disposed between the first atomizing seat 131 and the second atomizing seat 132 and connected to the first porous body 133 for liquid guiding, a pair of electrode posts 135, and a first electrode 136 and a second electrode 137 electrically connected to the atomizing core 134.

[0052] In some embodiments, the first atomizing seat 131 includes a liquid delivery channel 1311 formed therein, a pressure relief device 1312 communicating with the liquid delivery channel 1311, a first embedding groove 1313 with an opening, and a pair of second embedding grooves 1314 disposed on the bottom surface of the first atomizing seat 131. The liquid delivery channel 1311 connects the atomizing core 134 to the liquid storage assembly 12 and communicates with the liquid absorption surface of the atomizing core 134, so that the liquid aerosol generation matrix in the liquid storage assembly 12 enters the atomizing core 134 for heating and atomization. The pressure relief device 1312 is connected to the outside through a gap 1117 and an airflow channel 113 in sequence, and is used to relieve pressure when the liquid storage assembly 12 is pumped to ensure smooth liquid supply. The opening of the first embedding groove 1313 is connected to the liquid delivery channel 1311, and the first embedding groove 1313 is used to embed the atomizing core 134. The pair of second mounting slots 1314 are used to mount a pair of electrode posts 135.

[0053] In some embodiments, the infusion channel 1311 may include an inlet 1315 and a transverse channel 1316 connecting the inlet 1315 and the atomizing core 134.

[0054] In some embodiments, the liquid inlet 1315 may include a liquid inlet hole 1317 located at the upper end of the liquid inlet 1315, which is connected to the liquid outlet 1212 so that the liquid storage component 12 and the atomizing component 13 can communicate with each other.

[0055] In some embodiments, the transverse channel 1316 may include a first channel segment 1318, a second channel segment 1319, and a third channel segment 1320 sequentially connected in series in the direction from the liquid inlet 1315 to the atomizing core 134. In some embodiments, the first channel segment 1318 includes a first depth and a first width; in some embodiments, the second channel segment 1319 includes a first depth and a second width, the second width being greater than the first width, and the second width being approximately equal to the width of the liquid absorption surface of the atomizing core 134. In some embodiments, the third channel segment 1320 includes a second width and a second depth, the second depth being greater than the first depth, and the second depth being approximately equal to the height of the liquid absorption surface of the atomizing core 134. An exhaust port 1321 is provided on the upper side near the intersection of the second channel segment 1319 and the third channel segment 1320. The first channel segment 1318 is used to break up air bubbles generated on the first detection electrode 141 during the pumping process, thereby improving the accuracy of the detection. The third channel segment 1320 forms a temporary storage space for the liquid aerosol generation matrix to prevent dry burning.

[0056] In some embodiments, the pressure relief device 1312 may include a pressure relief pipe 1322 with a first air inlet and a first air outlet, and a pressure relief valve 1323 installed in the first air outlet, wherein the first air inlet is connected to the exhaust port 1321.

[0057] In some embodiments, the pressure relief valve 1323 may include a valve body and a plurality of pressure relief holes 1324 formed therein, each pressure relief hole 1324 having a diameter less than or equal to 0.5 mm. The cross-sectional dimensions (e.g., diameter, length, width, or cross-sectional area) of the pressure relief hole 1324 are relatively small, thereby generating surface tension. Due to this surface tension, the liquid aerosol generation matrix will not enter the airflow channel 113 from the pressure relief hole 1324. The pressure relief hole 1324 is positioned higher than the atomizing core 134 to reduce leakage. The pressure relief hole 1324 is connected to the outside environment sequentially through a gap 1117, the airflow channel 113, and a third outlet 112.

[0058] In some embodiments, the second atomizing base 132 includes a second atomizing base body 1326, a fixing member 1327 disposed within the second atomizing base body 1326, and a first bracket 1328. The fixing member 1327 cooperates with the first bracket 1328 to mount the first electrode 136 and the second electrode 137 on the second atomizing base body 1326.

[0059] In some embodiments, the first electrode 136 and the second electrode 137 can be electrode springs. One end of the first electrode 136 and the second electrode 137 are electrically connected to the atomizing core 134, and the other end is electrically connected to a pair of electrode posts 135. The first electrode 136 and the second electrode 137 can also serve as electrodes of the atomizing assembly 13 for electrical connection to the main unit's battery, thereby allowing the atomizing core 134 to heat and atomize the liquid aerosol generating matrix to form an aerosol. The second detection electrode is shared with the first electrode 136 and / or the second electrode 137. That is, one of the first electrode 136 and the second electrode 137 can be the second detection electrode, or both can be used as the second detection electrode.

[0060] In some embodiments, the first porous body 133 is preferably made of cotton. The first porous body 133 is disposed between the first detection electrode 141 and the second detection electrode of the liquid level detection assembly 14, and the first porous body 133 fills the third channel section 1320. When the liquid aerosol generating matrix in the infusion channel 1311 is not depleted, the first porous body 133 is used to absorb the liquid aerosol generating matrix in the infusion channel 1311 and supply it to the atomizing core 134 for heating and atomization. When the liquid aerosol generating matrix in the infusion channel 1311 is depleted, the surface tension of the first porous body 133 is used to absorb the liquid aerosol generating matrix or liquid aerosol generating matrix film remaining on the surface of the infusion channel 1311, to prevent misjudgment by the liquid level detection assembly 14 and ensure the accuracy of liquid level detection. Meanwhile, the first porous body 133 is in close contact with the liquid absorption surface of the atomizing core 134, which can also prevent the second porous body 1341 of the atomizing core 134 from forming air bubbles on the surface, thus preventing poor liquid supply and dry burning caused by air bubbles.

[0061] In some embodiments, the atomizing core 134 is rectangular and includes a longitudinally arranged liquid-absorbing surface, a second porous body 1341, and a heating element 1342 disposed on the second porous body 1341. The atomizer 1 includes a longitudinal axis, and the liquid-absorbing surface may be arranged parallel to the longitudinal axis of the atomizer 1 and in close contact with the first porous body 133. The material of the second porous body 1341 includes porous ceramic, porous glass ceramic, porous glass, or cotton. The second porous body 1341 is in liquid-conducting communication with the first porous body 133. In some embodiments, the heating element 1342 may be an S-shaped heating film. It is understood that in other embodiments, the heating element 1342 is not limited to a heating film; for example, it may also be a heating wire or a heating sheet. The shape of the heating element 1342 is also not limited to an S-shape; for example, it may also be spiral or mesh-like.

[0062] In some embodiments, the atomizing assembly 13 also includes a guide structure and a locking structure, which cooperate to securely connect the first atomizing seat 131 and the second atomizing seat 132.

[0063] In some embodiments, the guiding structure includes a plurality of guide posts 1330 disposed on the side wall of the second atomizing seat 132 near the first atomizing seat 131, and a plurality of guide holes 1331 disposed on the first atomizing seat 131 and engaging with the guide posts 1332. In some embodiments, the locking structure includes a latching hole 1332 disposed on the side wall of the second atomizing seat 132 near the first atomizing seat 131, and a latching hook 1333 disposed on the first atomizing seat 131 and engaging with the latching hole 1332.

[0064] In some embodiments, the liquid level detection assembly 14 may include a first detection electrode 141 and a second detection electrode for detecting the interruption of liquid flow in the infusion channel 1311. In some embodiments, the first detection electrode 141 is inverted T-shaped and includes a free end exposed in the second channel segment 1319 near the first channel segment 1318. One of the first electrode 136 and the second electrode 137 may be the second detection electrode, or both may serve as the second detection electrode. Understandably, in other embodiments, the second detection electrode may also be other electrodes electrically connected to the battery. This embodiment detects whether the liquid aerosol generation matrix in the infusion channel 1311 is depleted by detecting the on / off state of the first detection electrode 141 and the second detection electrode. When the liquid aerosol generating matrix in the infusion channel 1311 is not depleted, the first detection electrode 141 and the second detection electrode form a circuit. When the liquid aerosol generating matrix in the infusion channel 1311 is depleted, the first porous body 133 absorbs the liquid aerosol generating matrix or liquid aerosol generating matrix film remaining on the surface of the infusion channel 1311, so as to disconnect the circuit between the first detection electrode 141 and the second detection electrode, thereby ensuring the accuracy of liquid level detection in the infusion channel 1311. Here, the depletion of liquid aerosol generating matrix in the infusion channel 1311 means that the liquid aerosol generating matrix in the infusion channel 1311 cannot be used normally by the nebulizer 1 or that the infusion channel 1311 and the liquid level detection component 14 have a liquid aerosol generating matrix film attached to their surfaces.

[0065] In some embodiments, the air pumping conduit 15 may include a sealing sleeve 151, a silicone element 152 mounted on the lower end of the sealing sleeve 151, a one-way valve 153 mounted on the silicone element 152, an elastic element 154 sleeved on the one-way valve 153, and a first connector 155 mounted on the elastic element 154. The air pumping conduit 15 is used to transfer gas from the second outlet of the hose 242 in the power assembly 24 to the liquid reservoir 122.

[0066] In some embodiments, the sealing sleeve 151 is cylindrical, used to prevent outside air from entering the liquid storage shell 122 and causing contamination when the electronic atomizing device is not working. In some embodiments, the silicone element 152 is cylindrical, used to connect the second air outlet of the hose 231 of the power assembly 24 of the main unit 2 to the air pump pipe 15 via the second connector 243, with the silicone element 152 and the second connector 243 having a central connection. In some embodiments, the one-way valve 153 cooperates with the elastic element 154 to deliver gas unidirectionally to the liquid storage shell 122, preventing leakage. In some embodiments, the first connector 155 is cylindrical, including a lower pipe section 1551 and an upper pipe section 1552. The lower pipe section 1551 is installed at the upper end of the sealing sleeve 151 to seal the upper end face of the sealing sleeve 151; the upper pipe section 1552 is installed in the first receiving groove 1214 communicating with the second air inlet 2421 for guiding air.

[0067] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and do not limit the scope of protection of the present invention.
