The rollers 2383 may be cylindrical in shape and may be rotatably mounted between two cam blocks 2386 via roller shafts 2384. Specifically, two ends of the roller shaft 2384 can be respectively inserted on the two cam blocks 2386, and the roller 2383 is sleeved on the roller shaft 2384. There may be two rollers 2383, and the two rollers 2383 may be respectively disposed at both sides of the cam block 2386 in the length direction. The two rollers 2383 are in rolling friction with the flexible tube 237, thereby providing friction to creep the flexible tube 237 to effect delivery of the liquid.

As shown in fig. 3-4 and 9, the atomizer 1 may include an atomizing housing 11, a nozzle cover 12 disposed at an upper end of the atomizing housing 11, a base assembly 13 disposed at a lower end of the atomizing housing 11, and an atomizing core 17 and a vent tube 177 disposed in the atomizing housing 11 in some embodiments.

The buffer chamber 110 has a small liquid storage capacity and is mainly used for guiding the atomized liquid from the liquid supply tube 25 to the atomizing core 17, and the atomized liquid is heated and atomized by the atomizing core 17. In this embodiment, the atomizing cavity 113 is cylindrical and can be formed in the middle of the atomizing housing 11, two buffer cavities 110 are respectively located at two opposite sides of the atomizing cavity 113 in the circumferential direction, the two buffer cavities 110 can be respectively formed at two sides of the atomizing housing 11 along the length direction, and the two buffer cavities 110 are respectively communicated with the two liquid supply tubes 25 in a one-to-one correspondence manner. Each buffer chamber 110 may include a first buffer chamber 111 located at a lower portion and communicating with the liquid supply pipe 25, and a second buffer chamber 112 located at an upper portion and communicating with the first buffer chamber 111. The cross-sectional area of the second buffer chamber 112 may be larger than the cross-sectional area of the first buffer chamber 111. In this embodiment, the cross-sectional shape of the first buffer chamber 111 is a narrow and long shape, and the cross-sectional area of the first buffer chamber 111 is smaller, so that when the volume of the atomized liquid changes, the liquid level change is more obvious, and the liquid level detection is more sensitive. The cross-sectional area of the second buffer cavity 112 is larger, so that more atomized liquid can be buffered, and the atomized liquid is prevented from leaking from the pressure relief hole 1771 and other parts due to excessive liquid supply. First outlet port 114 may communicate with the bottom of first buffer chamber 111. In other embodiments, there may be only one buffer chamber 110 on one circumferential side of the nebulizing chamber 113, or there may be only one buffer chamber 110 around the nebulizing chamber 113.

The nozzle cover 12 is disposed at the upper opening of the atomizing housing 11 to seal the buffer chamber 110. An air outlet channel 120 is formed in the mouthpiece cover 12 for outputting aerosol for a user to inhale. The mouthpiece cover 12 may include a mouthpiece portion 121 and a sealing portion 122 in some embodiments. The nozzle part 121 is covered on the atomizing housing 11 and can be made of hard material such as plastic. The air outlet passage 120 may longitudinally penetrate the mouthpiece portion 121 and may be disposed coaxially with the mouthpiece portion 121. The sealing portion 122 is embedded in the mouthpiece portion 121, and may be made of a soft material such as silicone rubber, and is used for sealing the upper ends of the two buffer cavities 110.

The atomizing core 17 is disposed in the atomizing chamber 113 and is in liquid-conducting communication with the buffer chamber 110. The atomizing core 17 may include a liquid absorbing member 171 for absorbing the atomized liquid from the buffer chamber 110, a heat generating member 172 disposed on the liquid absorbing member 171, and two electrode leads 173 electrically connected to the positive and negative electrodes of the heat generating member 172, respectively. The liquid absorbing member 171 is a porous structure, which may be absorbent cotton, and is used for storing the atomized liquid and supplying the heat generating member 172 for heating and atomizing. In other embodiments, the wicking member 171 may also be a sintered porous structure, which may be made of a hard capillary structure such as porous ceramic, porous glass, etc.

The wicking member 171 may be cylindrical and may be disposed coaxially with the aerosolizing chamber 113. The inner wall surface of the liquid absorbing member 171 defines a heat generating chamber 1710, and the heat generating chamber 1710 is communicated with the air inlet hole 210 for realizing the mixing of aerosol and air. The heat generating member 172 may be a cylindrical metal heat generating sheet and may be disposed on an inner wall surface of the liquid absorbing member 171, and may heat and atomize the atomized liquid adsorbed in the liquid absorbing member 171 after being energized to generate aerosol. The liquid absorbing member 171 wraps the heat generating member 172, so that atomization can be more uniform. It is understood that in other embodiments, the heat generating member 172 may not be limited to a heat generating sheet, for example, it may also be a heat generating wire or a heat generating film; the shape of the heat generating member 172 is not limited to a cylindrical shape, and may be, for example, a spiral shape or a mesh shape. In other embodiments, the heat generating member 172 may be disposed on the outer surface of the liquid absorbing member 171.

In some embodiments, the atomizing core 17 may further include a fixing tube 175 sleeved outside the liquid absorbing member 171, and an atomizing base 174 embedded in a lower opening of the fixing tube 175. The fixing tube 175 may have a circular tube shape and may be made of a hard material such as metal, plastic, etc. for supporting the fixing suction member 171. The stationary tube 175 defines at least one fluid inlet 1750 for communicating the fluid suction member 171 with the buffer chamber 110. In this embodiment, there are three liquid inlet holes 1750, and the three liquid inlet holes 1750 may be spaced apart from each other in the circumferential direction of the fixed pipe 175. Further, the fixing tube 175 may further have a slot 1751 formed thereon, and the slot 1751 may be formed by extending the upper end surface of the fixing tube 175 downward in the axial direction, so that the upper end opening of the fixing tube 175 has a certain elasticity, and the liquid absorbing member 171 can be inserted into the fixing tube 175 from the upper end opening of the fixing tube 175 conveniently. In addition, the slot 1751 may also be used to connect the liquid suction member 171 to the buffer chamber 110, and the slot 1751 and the three liquid inlet holes 1750 may be evenly spaced along the circumference of the fixed pipe 175.

The atomizing base 174 is fitted into the lower opening of the fixed tube 175, and the outer wall surface of the atomizing base 174 is in sealing engagement with the inner wall surface of the fixed tube 175. In some embodiments, the atomizing base 174 can be made of soft material such as silicon. The atomizing base 174 may be formed with an air guide hole 1740 for communicating the heating cavity 1710 with the air inlet hole 210 and two lead through holes 1741 for the two electrode leads 173 to pass through, respectively, along the longitudinal direction.

In some embodiments, the atomizing core 17 can further include a liquid guiding member 176 sleeved outside the fixing tube 175. The liquid guiding member 176 is cylindrical and is sleeved between the air pipe 177 and the fixing pipe 175, the outer wall surface and the inner wall surface of the liquid guiding member are respectively contacted with the air pipe 177 and the fixing pipe 175, and the atomized liquid entering from the air pipe 177 through the infiltration and capillary effects of the inner micropores of the liquid guiding member 176 can be quickly and uniformly conducted to the fixing pipe 175. The liquid guiding member 176 is a porous structure, which may be a liquid guiding cotton, and in other embodiments, it may also be a hard porous structure such as porous ceramic, porous glass ceramic, and porous glass.

The vent tube 177 may include a first lower tube section 1772 and a second upper tube section 1773, the first tube section 1772 having an inner diameter and an outer diameter that may be greater than the inner diameter and the outer diameter, respectively, of the second tube section 1773. The stationary tube 175, the liquid guide 176, and the liquid absorbing member 171 can be received in the first tube section 1772. At least one liquid guiding hole 1770 is formed in the first pipe segment 1772, so that the atomized liquid in the buffer chamber 110 can enter the air pipe 177 through the at least one liquid guiding hole 1770 and be adsorbed by the liquid guiding member 176. In this embodiment, there are four liquid guiding holes 1770, the four liquid guiding holes 1770 may be uniformly distributed along the circumferential direction of the first pipe section 1772 at intervals, and the four liquid guiding holes 1770 may be respectively in one-to-one correspondence communication with the slots 1751 and the three liquid inlet holes 1750.

The upper end of second tubular segment 1773 can be embedded in outlet channel 120 and is in communication with outlet channel 120. The wall surface of the second pipe segment 1773 may further have at least one pressure release hole 1771, and the buffer chamber 110 may communicate with the outside through the pressure release hole 1771, so that pressure release may be achieved when the liquid supply pipe 25 supplies liquid to the buffer chamber 110, so as to smooth the liquid supply. In this embodiment, two supply tubes 25 are respectively located at two circumferential sides of the vent tube 177, the at least one pressure relief hole 1771 may be opened at one side or two sides of the second tube segment 1773, for example, the at least one pressure relief hole 1771 may be opened at a side of the second tube segment 1773 corresponding to one of the supply tubes 25; alternatively, at least one pressure release hole 1771 may be formed at both circumferential sides of the second pipe segment 1773 corresponding to the two supply pipes 25, respectively. In other embodiments, when the number of the liquid supply tubes 25 is one and the pressure relief hole 1771 is disposed on one circumferential side of the vent tube 177, the pressure relief hole 1771 may be opened on a side of the second tube section 1773 corresponding to the one liquid supply tube 25.

The pressure relief hole 1771 has a small cross-sectional dimension (e.g., aperture, length, width, or cross-sectional area) to generate surface tension, and thus the atomized liquid will not enter the vent tube 177 from the buffer chamber 110 due to the surface tension. It will be appreciated that the smaller the cross-sectional dimension of the pressure relief vent 1771, the higher the cost of the vent. In general, the cross-sectional size of the pressure relief hole 1771 may be selected as appropriate depending on the material of the vent tube 177, the viscosity of the atomized liquid, the cost of the holes, and the like. For example, when the viscosity of the atomized liquid is high, the cross-sectional size of the pressure release hole 1771 can be increased as appropriate; when the viscosity of the liquid is low, the cross-sectional size of the pressure relief hole 1771 can be reduced appropriately. In this embodiment, the pressure relief hole 1771 is a circular hole, the diameter phi of the pressure relief hole 1771 is 0.4-1.0 mm, preferably 0.6-0.8 mm, and in this size range, the pressure relief hole 1771 has good air and liquid permeability resistance and moderate opening cost. In other embodiments, the pressure relief hole 1771 may be an oval or square hole, and the length or width of the pressure relief hole 1771 may be 0.4-1.0 mm, preferably 0.6-0.8 mm.

The pressure relief hole 1771 is positioned higher than the atomizing core 17 to reduce leakage. Furthermore, the pressure relief hole 1771 can be higher than the second buffer chamber 112, so that the leakage-proof effect is better. In other embodiments, the pressure relief hole 1771 may be located flush with the upper end surface of the atomizing core 17 or the upper end surface of the second buffer chamber 112. A second liquid outlet 115 communicated with the second buffer chamber 112 may be further formed in the atomizing housing 11, a pressure relief passage 1774 communicating the second buffer chamber 112 with the pressure relief hole 1771 may be further formed between an outer wall surface of the second pipe section 1773 and an inner wall surface of the atomizing housing 11 and an inner wall surface of the atomizing cover 12, and the second buffer chamber 112 is sequentially communicated with the outside through the second liquid outlet 115, the pressure relief passage 1774, the pressure relief hole 1771, and the air outlet passage 120.

Further, the atomizer 1 may further include a liquid accumulation member 178 sleeved outside the first pipe section 1772. The liquid accumulation member 178 is porous and can store a certain amount of atomized liquid, which in this embodiment can be liquid accumulation cotton. In other embodiments, the liquid accumulation member 178 may also be a hard porous structure such as porous ceramic, porous glass, etc. The liquid accumulation member 178 can rapidly and uniformly introduce the atomized liquid in the buffer chamber 110 into the first tube segment 1772 by the infiltration and capillary effect of the inner micropores thereof.

In addition, the lower end of the liquid accumulation member 178 can be communicated with the first buffer cavity 111 through the first liquid outlet 114, and the upper end of the liquid accumulation member 178 can be communicated with the second buffer cavity 112 through the second liquid outlet 115, so that the liquid accumulation member 178 can adsorb the atomized liquid in the second buffer cavity 112, and the liquid leakage caused by the free atomized liquid in the second buffer cavity 112 is prevented.

The base assembly 13 is embedded in the lower opening of the atomizing housing 11, and the atomizer 1 can be mounted on the main machine 2 via the base assembly 13. After the atomizer 1 is assembled with the main body 2, an air flow gap 280 communicating with the air inlet hole 210 may be formed between the bottom surface of the base assembly 13 and the upper end surface of the bracket assembly 28. The base assembly 13 may have at least one liquid supply channel 1320 connecting the at least one liquid supply tube 25 to the at least one first buffer chamber 111 and at least one vent 1310 connecting the air flow gap 280 to the heat generating chamber 1710. In this embodiment, two liquid supply channels 1320 are provided at two sides of the base assembly 13 along the length direction, and the upper ends of the two liquid supply pipes 25 are inserted into the two liquid supply channels 1320.

In some embodiments, the base assembly 13 may include a base 131 and a sealing seat 132 disposed on an upper end of the base 131. The base 131 may be made of a hard material such as plastic. The vent hole 1310 may be formed on the base 131 in a longitudinal direction. In the present embodiment, the two vent holes 1310 are provided and may be respectively located at both sides of the base 131 in the width direction. The upper end surface of the vent hole 1310 may be higher than the surface of the base 131 around the circumference thereof, so that leakage of liquid through the vent hole 1310 may be reduced.

The sealing seat 132 may be made of soft material such as silica gel. The outer surface of the sealing seat 132 is in sealing engagement with the inner surface of the atomizing housing 11 to prevent leakage. The liquid supply passage 1320 may be formed on the sealing seat 132, and after the liquid supply tube 25 is inserted into the liquid supply passage 1320, the soft sealing seat 132 wraps the liquid supply tube 25, thereby reducing liquid leakage. In addition, a blocking wall 1321 may be further formed in the liquid supply channel 1320, the blocking wall 1321 may be located at the bottom of the liquid supply channel 1320 and may be in an upwardly concave circular arc shape, a slot in a shape of a straight groove is formed on the blocking wall 1321, when the atomizer 1 is inserted into the host 2, the liquid supply pipe 25 may pass through the slot on the blocking wall 1321 to communicate with the first buffer chamber 111, and after the atomizer 1 is pulled out from the host 2, the slot on the blocking wall 1321 is closed and sealed to prevent the atomized liquid in the buffer chamber 110 from flowing out. It is understood that in other embodiments, the slot formed in the blocking wall 1321 may have other shapes such as a Y-shaped slot, a cross-shaped slot, etc.

The nebulizer 1 may also include at least one support tube 15 embedded in the at least one liquid supply channel 1320 in some embodiments to communicate the liquid supply tube 25 with the first buffer chamber 111. The support tube 15 is a hard support tube, and may be made of a hard material such as metal. The support tube 15 is embedded at the upper part of the liquid supply channel 1320 and has a short axial length for supporting the soft liquid supply channel 1320, so as to avoid the problems of inconvenient assembly, poor appearance and reduced reliability caused by the long length of the liquid supply tube 25 or the problem of insufficient support caused by the long length of the soft liquid supply channel 1320. The support pipe 15 may not be in direct contact with the liquid supply pipe 25, and damage caused by collision of the support pipe 15 with the liquid supply pipe 25 when the atomizer 1 is assembled with the main body 2 may be avoided. Specifically, in the present embodiment, a certain interval is formed between the lower end surface of the support pipe 15 and the upper end surface of the liquid supply pipe 25, and the inner diameter of the support pipe 15 may be larger than the outer diameter of the liquid supply pipe 25.

The atomizer 1 may further comprise at least one second electrode column 16 longitudinally embedded on the base assembly 13. The upper end of the second electrode column 16 may communicate with the heat generating chamber 1710 and be close to the electrode lead 173. Generally, there are two second electrode columns 16, and the two second electrode columns 16 are electrically connected to two electrode leads 173, respectively. When the atomizer 1 is inserted into the main unit 2, the lower ends (the ends facing the battery 22) of the two second electrode posts 16 are in contact conduction with the upper ends (the ends facing the nozzle cover 12) of the two first electrode posts 26, respectively. Each second electrode column 16 and the corresponding conductive first electrode column 26 form an electrode assembly 60, and the electrode assembly 60 is preferably an elastic electrode assembly.

Further, the electronic atomization device may further include a liquid level detection system to detect whether the atomized liquid in the buffer chamber 110 is sufficient, and the liquid transmission assembly 23 may start or stop the liquid supply according to a detection result of the liquid level detection system, for example, start the liquid supply when the detection result is that the liquid is insufficient, and stop the liquid supply when the detection result is that the liquid is present. The liquid level detection system is not limited in liquid level detection mode, and can be used in various modes such as capacitance, resistance and the like, as long as the atomized liquid in a free state can be detected.

In the present embodiment, the liquid supply tube 25 is electrically conductive and may be made of a conductive material such as metal. The upper end of the liquid supply pipe 25 is communicated with the buffer chamber 110, and the lower end is communicated with the liquid transmission assembly 23. The end of the supply tube 25 in communication with the liquid delivery assembly 23 may be electrically connected to the controller 24. The electrode assembly 60 has an upper end electrically connected to the heat generating member 172 and a lower end electrically connected to the controller 24. One end of the liquid supply pipe 25, which is connected with the controller 24, can be used as a detection anode of the liquid level detection system, and one end of the electrode assembly 60, which is connected with the controller 24, can be used as a detection cathode of the liquid level detection system; of course, the liquid supply pipe 25 may be connected to one end of the controller 24 as a negative detection electrode, and the electrode assembly 60 may be connected to one end of the controller 24 as a positive detection electrode. If the liquid supply pipe 25 and the heating element 172 are simultaneously contacted with the atomized liquid and conducted through the atomized liquid to form a passage, the controller 24, the liquid supply pipe 25, the atomized liquid in the buffer cavity 110, the heating element 172, the electrode assembly 60 and the controller 24 are sequentially conducted to form a liquid level detection circuit loop, which indicates that the atomized liquid in the buffer cavity 110 is sufficient, so that the liquid transmission assembly 23 stops supplying liquid to the buffer cavity 110, and leakage caused by too much atomized liquid in the buffer cavity 110 is avoided; the atomized liquid is gradually consumed along with the pumping and heating, and the free atomized liquid in the buffer chamber 110 will be immediately supplemented to the liquid accumulation member 178, the liquid guiding member 176 and the liquid absorbing member 171 until the circuit is broken. When the circuit between the liquid supply tube 25 and the heat generating member 172 is broken, it indicates that the atomized liquid in the buffer cavity 110 is insufficient, the liquid transmission assembly 23 can be opened to supply the liquid to the buffer cavity 110, the supplied atomized liquid first fills the liquid accumulation member 178, the liquid guiding member 176 and the liquid absorbing member 171, when a certain amount of atomized liquid in a free state appears in the buffer cavity 110, the liquid supply tube 25 and the heat generating member 172 can be opened, and the liquid transmission assembly 23 stops supplying the liquid.

Whether atomized liquid exists in the buffer cavity 110 is judged by the on-off of the circuit between the liquid supply pipe 25 and the electrode assembly 60, the structure is simple, the result is reliable, the automatic liquid injection response is fast, and dry burning and liquid leakage can be avoided. Specifically, the controller 24 may determine whether a passage is formed between the liquid supply tube 25 and the electrode assembly 60, and if so, output a closing signal to the liquid delivery assembly 23 to stop the liquid delivery from the liquid delivery assembly 23; if not, an opening signal for opening the liquid supply of the liquid transmission assembly 23 is output to the liquid transmission assembly 23. The close signal and/or the open signal can be immediately transmitted to the liquid transmission assembly 23, so that the liquid transmission assembly 23 immediately stops supplying liquid and/or starts supplying liquid. In other embodiments, the controller 24 may further include a delay module for delaying the turning on or off of the liquid delivery assembly 23.

In another embodiment, the liquid level detection system may control the liquid delivery assembly 23 to start the liquid supply when detecting a circuit break between the liquid supply tube 25 and the electrode assembly 60, and the liquid delivery assembly 23 stops pumping after a certain period of time. Most of the atomized liquid pumped by the liquid conveying assembly 23 can be stored by the liquid accumulating part 178, the liquid guiding part 176 and the liquid absorbing part 171, and the heat generating part 172 heats and atomizes the atomized liquid. When the atomized liquid is consumed, the system will again detect a break between the supply tube 25 and the electrode assembly 60, and turn on the liquid delivery assembly 23 to continue pumping. The time and the amount of the liquid pumped at one time can be determined according to parameters such as the liquid supply speed, the atomization speed, the capacity of the buffer chamber 110, and the like, for example, the time and the amount of the liquid pumped at one time can be 1-5 s and 15-50 mg.

The end surfaces of the two ends of the liquid supply tube 25 are electrically conductive, and the liquid supply tube 25 can be respectively connected to the atomized liquid in the buffer cavity 110 and the controller 24 through the end surfaces of the two ends. The end surfaces of the two ends of the first electrode column 26 and the second electrode column 16 are electrically conductive, the lower end surface of the first electrode column 26 is electrically connected to the controller 24, the upper end surface of the first electrode column 26 is electrically connected to the lower end surface of the second electrode column 16, and the upper end surface of the second electrode column 16 is electrically connected to the heating element 172. Specifically, the outer peripheries of the liquid supply tube 25, the first electrode column 26 and the second electrode column 16 are insulated, for example, an insulating layer (e.g., an insulating sleeve, an insulating coating, a silicone flange, etc.) may be wrapped on the outer wall surfaces of the liquid supply tube 25 and/or the first electrode column 26 and/or the second electrode column 16 to insulate the outer peripheries thereof, so that the reliability of the circuit between the liquid supply tube 25 and the electrode assembly 60 may be improved, and misjudgment of a path between the liquid supply tube 25 and the electrode assembly 60 due to liquid leakage may be prevented, thereby preventing the heat generating member 172 from being dried. Specifically, the liquid supply tube 25 communicates at the upper end with the buffer chamber 110 and the area outside the lower end connection controller 24 and the electrode assembly 60 communicates at the upper end with the heat generation chamber 1710 and the area outside the lower end connection controller 24, and the outer circumferential surface of the liquid supply tube 25 is absolutely insulated from the outer circumferential surface of the electrode assembly 60. In the present embodiment, the supply tube 25 and the electrode assembly 60 are insulated from each other at a predetermined region by the insulating sealing seat 132 and the first sealing sleeve 27 wrapping the outer wall surface of the supply tube 25.

Further, in order to further improve the reliability of the circuit between the liquid supply tube 25 and the electrode assembly 60, a disconnection detecting module may be further provided to perform disconnection detection of the liquid supply tube 25 and/or the electrode assembly 60. By performing the disconnection detection of the liquid supply tube 25 itself, it is possible to prevent the problem of the continuous liquid supply and the serious liquid leakage caused by the disconnection due to the failure of the liquid supply tube 25 itself. By detecting the open circuit of the electrode assembly 60, if the electrode assembly 60 fails and causes the open circuit, it is determined that the second electrode column 16 and the first electrode column 26 are not conducted, and it is determined that the atomizer 1 is not connected to the host machine 2 and the system does not work. In some embodiments, the disconnection detection may be implemented by a redundant design, for example, at least two parallel wires may be led from the controller 24 to the liquid supply pipe 25, and if the disconnection occurs due to a failure of the liquid supply pipe 25, the controller 24 outputs a closing signal for stopping the liquid supply to the liquid delivery assembly 23.

Further, each liquid supply tube 25 and the electrode assembly 60 on the corresponding side form a liquid level detection circuit, so that double-side liquid level detection of the buffer cavities 110 on the two sides is realized, and a situation that the electronic atomization device is obliquely used can be considered. During detection, if the liquid level detection on the two sides is a passage, the liquid conveying assembly 23 stops supplying liquid; if one side of the channel is broken, the liquid transmission assembly 23 stops supplying liquid; if the liquid level detection on both sides is open, the liquid transmission assembly 23 starts to supply liquid. It will be appreciated that in other embodiments, the level detection circuit may be provided on only one side.

It is understood that in other embodiments, the liquid level of the nebulizer 1 may be detected by other liquid level detecting structures, for example, a liquid level detecting element may be additionally disposed in the buffer chamber 110 for liquid level detection.

As shown in fig. 10, the liquid level detection circuit in this embodiment includes a MOS transistor U1, a resistor R1, a resistor R2, a resistor R3, and an operational amplifier Q1.

The controller 24 comprises an MCU, an OIL _ EN pin of the MCU is connected with a grid electrode of an MOS tube U1, an AD _ T pin of the MCU acquires a sampling signal output by an operational amplifier Q1 in real time, a VCC pin of the MCU is connected with a power supply anode, and a GND pin of the MCU is grounded.
