[0009] As one implementation of the first aspect, the connection channel includes at least one liquid guide hole, the cross-sectional size of which is capable of restricting the aerosol matrix from flowing out of the liquid guide hole under non-driving conditions.
[0010] As one implementation of the first aspect, the liquid guiding structure further includes a liquid guiding plug that is interference-fitted into the connecting channel. The peripheral sidewall of the liquid guiding plug is provided with a plurality of liquid guiding grooves, all of which extend along the axial direction of the liquid guiding plug. The groove wall of the liquid guiding groove and the channel wall of the connecting channel together form a liquid guiding hole. The cross-sectional size of the liquid guiding hole is such that the aerosol matrix can remain in the liquid guiding hole in the absence of pressure difference.
[0011] As one implementation of the first aspect, the liquid guiding structure further includes a baffle connected to the shell body and covering the channel opening of the connecting channel. The baffle has at least one perforation connecting the first liquid storage chamber and the connecting channel. The cross-sectional size of the perforation can restrict the aerosol matrix from flowing out of the perforation under non-driving conditions. The liquid guiding plug is spaced apart from the baffle.
[0012] As one implementation of the first aspect, the connection channel further includes a shaft hole formed in the liquid guide plug, the shaft hole being formed along the axial direction of the liquid guide plug, and a plurality of liquid guide grooves being arranged around the shaft hole.
[0013] As one implementation of the first aspect, the atomizing component further includes a liquid storage cotton disposed in the first liquid storage chamber, wherein multiple perforations are provided, and the liquid storage cotton covers at least one of the perforations while avoiding at least one of the perforations.
[0014] As one implementation of the first aspect, the liquid guiding structure includes a first connecting pipe connected to the shell body and a second connecting pipe connected to the liquid storage tank, the second connecting pipe being sleeved outside the first connecting pipe, and the first connecting pipe and the second connecting pipe together forming the connecting channel.
[0015] As one implementation of the first aspect, the liquid guiding structure further includes a third connecting pipe and a sealing ring. The third connecting pipe is connected to the shell body and surrounds the first connecting pipe. The third connecting pipe is spaced apart from the second connecting pipe. The sealing ring is sleeved on the second connecting pipe and seals between the second connecting pipe and the third connecting pipe.
[0016] As one implementation of the first aspect, the liquid storage tank includes a liquid storage shell and an end cap. The liquid storage shell forms a second liquid storage cavity and an opening. The end cap covers the opening and is capable of elastic deformation.
[0017] As one implementation of the first aspect, the liquid storage tank is snapped onto the shell body.
[0018] As one implementation of the first aspect, the shell body has a first connecting hole communicating with the first liquid storage chamber, the liquid storage compartment has a second connecting hole communicating with the second liquid storage chamber, the connecting channel is connected to the first connecting hole and the second connecting hole, and the atomizer further includes a first sealing plug and a second sealing plug. The first sealing plug is detachably connected to the first connecting hole and is used to block the first connecting hole, and the second sealing plug is detachably connected to the second connecting hole and is used to block the second connecting hole.
[0019] As one implementation of the first aspect, the shell body includes an outer shell and a supporting shell. The outer shell forms an installation cavity and a viewing hole communicating with the installation cavity. The supporting shell is disposed in the installation cavity and forms the first liquid storage cavity. The supporting shell covers the viewing hole and is able to transmit light.
[0020] Secondly, an electronic atomizing device is provided, including the atomizer described in the above embodiments.
[0021] The technical advantages of this invention compared to existing technologies are as follows: When needed, the atomizer can be compressed and deformed by external force, reducing the volume of the second storage chamber. This allows the aerosol matrix in the second storage chamber to enter the first storage chamber through the connecting channel. The atomizing core absorbs the aerosol matrix and atomizes it for the user to inhale. After the user replenishes the aerosol matrix, the storage chamber returns to its original shape, the volume of the second storage chamber increases, and the air pressure decreases. Under the pressure difference, the gas in the atomization channel can enter the first storage chamber through the vent, and then enter the second storage chamber through the connecting channel, thus restoring the storage chamber to its original state. Furthermore, because the cross-sectional size of the vent restricts the aerosol matrix from flowing out of the vent without driving, the aerosol matrix in the first storage chamber can seal the vent through its own surface tension, remaining within the first storage chamber and preventing leakage. In this way, the atomizer can achieve liquid intake by setting a deformable liquid storage chamber, and effectively balance the air pressure in the second liquid storage chamber by opening a vent on the atomizing core.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0037] This utility model provides an atomizer and an electronic atomizing device. The electronic atomizing device includes an atomizer and a battery compartment. The battery compartment contains a battery and a control board. The battery compartment can be connected to the atomizer to supply power to the atomizer and control the atomizer. The battery compartment can also be magnetically attached to the atomizer.
[0038] Please see Figure 1 and Figure 2 The atomizer includes an atomizing chamber 10, a liquid storage chamber 20, and a liquid guiding structure 30. The atomizing chamber 10 and the liquid storage chamber 20 are connected through the liquid guiding structure 30. The liquid storage chamber 20 is used to supply the atomizing chamber 10 with the aerosol matrix, and the atomizing chamber 10 is used to atomize the aerosol matrix so that the user can inhale the atomized aerosol matrix into their mouth.
[0039] The atomizing chamber 10 includes a shell body 11 and an atomizing assembly 12. The shell body 11 forms a first liquid storage chamber 101, and the atomizing assembly 12 includes an atomizing core 121, which passes through the first liquid storage chamber 101 and forms an atomizing channel 120. The portion of the first liquid storage chamber 101 outside the atomizing channel 120 forms a liquid storage space, which is used to store the aerosol matrix.
[0040] Specifically, the shell body 11 also forms an air inlet channel 102 and an air outlet channel 103. Both the air inlet channel 102 and the air outlet channel 103 are connected to the first liquid storage chamber 101. The two ends of the atomizing core 121 are respectively connected to the air outlet of the air inlet channel 102 and the air inlet of the air outlet channel 103, so that the atomizing channel 121 is connected to the air inlet channel 102 and the air outlet channel 103. The atomizing core 121 includes a fiberglass tube, an atomizing tube, a liquid-coated cotton, and a heating wire. The fiberglass tube is sleeved on the outside of the atomizing tube and is connected to the air outlet of the air inlet channel 102 and the air inlet of the air outlet channel 103. The atomizing tube is completely located inside the first liquid storage chamber 101. The atomizing tube has an atomizing hole. The liquid-coated cotton is connected to the atomizing tube and covers the atomizing hole. The heating wire is disposed on the liquid-coated cotton and is electrically connected to the circuit board in the battery compartment through pins. The control panel can control the heating wire to generate heat, so as to atomize the aerosol matrix absorbed on the liquid-coated cotton into the atomization channel 120.
[0041] The atomizing core 121 has a vent 1210 that connects the atomizing channel 120 and the first liquid storage chamber 101. Specifically, the vent 1210 can be formed on the fiberglass tube, in which case the vent 1210 is close to the air outlet of the air inlet channel 102. Of course, in other embodiments, the vent 1210 can also be close to the air inlet of the air outlet channel 103, and there is no limitation here.
[0042] The cross-sectional dimensions of the vent 1210 restrict the aerosol matrix from flowing out of the vent 1210 under undriven conditions. Understandably, the driving conditions for the aerosol matrix include, but are not limited to, pressure difference, temperature, mechanical force, chemical action, and external fields. The vent 1210 has a microporous structure; under undriven conditions, the aerosol matrix can be retained at the orifice or within the vent 1210 using its surface tension. Under driven conditions, the aerosol matrix can flow within the vent 1210.
[0043] It should be noted that the cross-section of the vent 1210 can be circular, polygonal, or irregular. The maximum width of the vent 1210 is limited to being less than or equal to the critical capillary diameter of the aerosol matrix on the vent wall material, ensuring that the aerosol matrix is stably attached to the vent 1210 due to capillary force generated by surface tension when no external driving force is present. Alternatively, the cross-section of the vent 1210 can also be elongated; in this case, the width perpendicular to the extension direction of the vent 1210 needs to be limited to being less than or equal to the critical capillary diameter of the aerosol matrix on the vent wall material.
[0044] The liquid storage tank 20 can be connected to the shell body 11 and forms a second liquid storage cavity 201, which is used to store the aerosol matrix. The liquid guiding structure 30 connects the shell body 11 and the liquid storage tank 20 and forms a connecting channel 301 that connects the first liquid storage cavity 101 and the second liquid storage cavity 201.
[0045] The liquid storage tank 20 can increase or decrease the volume of the second liquid storage chamber 201 by its own deformation. The user can compress and deform the liquid storage tank 20 by squeezing it or by controlling the electric mechanism, thereby reducing the volume of the second liquid storage chamber 201 and increasing the air or hydraulic pressure. Under this pressure difference, the aerosol matrix within the second liquid storage chamber 201 can enter the first liquid storage chamber 101 through the connecting channel 301. When the user releases the pressure on the liquid storage tank 20 or controls the electric mechanism to release the pressure, the liquid storage tank 20 can return to its original shape through its own elastic restoring force or the mechanical force of the electric mechanism, thus increasing the volume of the second liquid storage chamber 201 to its initial value.
[0046] When needed, the atomizer can be compressed and deformed by external force to reduce the volume of the second storage chamber 201. This allows the aerosol matrix in the second storage chamber 201 to enter the first storage chamber 101 through the connecting channel 301. The atomizing core 121 absorbs the aerosol matrix and atomizes it for the user to inhale. After the user replenishes the aerosol matrix, the storage chamber 20 returns to its original shape, the volume of the second storage chamber 201 increases, and the air pressure decreases. Under the pressure difference, the gas in the atomizing channel 120 can enter the first storage chamber 101 through the vent 1210, and then enter the second storage chamber 201 through the connecting channel 301, thus restoring the storage chamber 20 to its original state. Since the cross-sectional dimensions of the vent 1210 can restrict the aerosol matrix from flowing out of the vent 1210 under no-drive conditions, the aerosol matrix in the first liquid storage chamber 101 can seal the vent 1210 through its own surface tension and remain within the first liquid storage chamber 101, preventing leakage of the aerosol matrix from the vent 1210. In this way, the atomizer can achieve liquid intake by setting a deformable liquid storage chamber 20, and effectively balance the air pressure in the second liquid storage chamber 201 by opening the vent 1210 on the atomizing core 121.
[0047] Please see Figure 2 In some embodiments, the liquid storage chamber 20 includes a liquid storage shell 21 and an end cap 22. The liquid storage shell 21 forms a second liquid storage cavity 201 and an opening. The end cap 22 closes onto the opening and is elastically deformable. When the user needs to replenish the aerosol matrix into the first liquid storage cavity 101, the user can press the end cap 22 to elastically deform it toward the second liquid storage cavity 201. At this time, the volume of the second liquid storage cavity 201 decreases, and the air pressure above the aerosol matrix in the second liquid storage cavity 201 increases, pushing the aerosol matrix into the first liquid storage cavity 101 through the connecting channel 301. In this way, the user can manually replenish the aerosol matrix. After the user releases their grip, the end cap 22 automatically resets due to its elastic restoring force, reducing the air pressure above the aerosol in the second liquid storage chamber 201. Air in the atomizing channel 120 then enters the second liquid storage chamber 201 through the vent 1210 under pressure differential, maintaining pressure balance between the second liquid storage chamber 201 and the external environment. When the atomizing core 121 operates, it consumes the aerosol matrix in the first liquid storage chamber 101. Air pressure in the first liquid storage chamber 101 also balances with external pressure through the vent 1210. The end cap 22 may be partially or entirely supported by rubber to allow for elastic deformation under user pressure.
[0048] Optionally, the end cap 22 is detachably connected to the liquid storage shell 21. When it is necessary to replenish the aerosol matrix into the second liquid storage chamber 201, the end cap 22 can be removed from the opening of the liquid storage shell 21, thus enabling the continuous use of the atomizer.
[0049] Please see Figure 2 and Figure 3 In some embodiments, the liquid storage tank 20 is detachably connected to the shell body 11 to facilitate production and assembly. Specifically, the shell body 11 has a first connection hole 104 connecting the first liquid storage chamber 101 to the external space, and the liquid storage tank 20 has a second connection hole 202 connecting the second liquid storage chamber 201 to the external space. One end of the liquid guiding structure 30 is connected to the opening of the first connection hole 104, and the other end is connected to the opening of the second connection hole 202, so that the connecting channel 301 is connected to the first connection hole 104 and the second connection hole 202.
[0050] Optional, combined Figure 4 The atomizer also includes a first sealing plug 40, which is detachably connected to the first connection hole 104 and used to seal the first connection hole 104. In this way, the atomizing chamber 10 can be transported and sold separately. The first liquid storage chamber 101 can store a portion of the aerosol matrix so that the atomizing chamber 10 can be used independently.
[0051] Optional, combined Figure 5The atomizer also includes a second sealing plug 50, which is detachably connected to the second connection hole 202 and used to seal the second connection hole 202. This allows the liquid storage tank 20 to be transported and sold separately. The liquid storage tank 20 can supplement the atomizing tank 10; when the atomizing tank 10 alone cannot meet the user's needs, the liquid storage tank 20 can be installed into the atomizing tank 10. The liquid storage tank 20 may or may not be removed after installation into the atomizing tank 10; this is not a restriction.
[0052] Optionally, the liquid storage chamber 20 is snapped into the atomizing chamber 10 to facilitate quick assembly of the liquid storage chamber 20 and the atomizing chamber 10. Specifically, the atomizing chamber 10 also includes a first extension plate 13 and a second extension plate 14 connected to the shell body 11. The first extension plate 13 and the second extension plate 14 are spaced apart. The first extension plate 13 is provided with a first locking position 131, and the second extension plate 14 is provided with a second locking position 141. The liquid storage chamber 20 is snapped into the first locking position 131 and the second locking position 141.
[0053] Furthermore, the first extension plate 13 is provided with a notch 132, the end cap 22 is provided with a first snap-fit structure 23, and the bottom of the liquid storage shell 21 is provided with a second snap-fit structure 24. The first snap-fit structure 23 is snapped into the first snap-fit position 131, the second snap-fit structure 24 is snapped into the second snap-fit position 141, and the end cap 22 is exposed at the notch 132 to facilitate user pressing.
[0054] In other embodiments, the liquid storage chamber 20 may also be fixedly connected to the atomizing chamber 10 and assembled for sale, in which case the atomizer does not include the first sealing plug 40 and the second sealing plug 50.
[0055] Please see Figure 2 In some embodiments, the liquid guiding structure 30 includes a first connecting pipe 31 connected to the shell body 11 and a second connecting pipe 32 connected to the liquid storage chamber 20. The second connecting pipe 32 is sleeved outside the first connecting pipe 31, and the first connecting pipe 31 and the second connecting pipe 32 together form a connecting channel 301. The sleeved connection of the first connecting pipe 31 and the second connecting pipe 32 enables rapid positioning of the liquid storage chamber 20 and the atomizing chamber 10. The first connecting pipe 31 is connected to the first connecting hole 104, and the second connecting pipe 32 is connected to the second connecting hole 202. A first sealing plug 40 is detachably connected to the first connecting pipe 31, and a second sealing plug 50 is detachably connected to the second connecting pipe 32.
[0056] Optional, combined Figure 4 When the atomizer is equipped with a first sealing plug 40, the first sealing plug 40 is sleeved on the outside of the first connecting tube 31.
[0057] Optional, combined Figure 5The second sealing plug 50 can be inserted into the second connecting tube 32. When the atomizing chamber 10 and the liquid storage chamber 20 are connected, the first connecting tube 31 can push the second sealing plug 50 into the second liquid storage chamber 201 when it is inserted into the second connecting tube 32. In this way, the second sealing plug 50 does not need to be removed, which facilitates the quick connection between the liquid storage chamber 20 and the atomizing chamber 10.
[0058] Optionally, the liquid guiding structure 30 further includes a third connecting pipe 33 and a sealing ring 34. The third connecting pipe 33 is connected to the shell body 11 and surrounds the first connecting pipe 31. The third connecting pipe 33 is spaced apart from the second connecting pipe 32. The sealing ring 34 is sleeved on the second connecting pipe 32 and seals between the second connecting pipe 32 and the third connecting pipe 33. The sealing ring 34 can achieve the sealing of the connection channel 301. The arrangement of the third connecting pipe 33 makes the leakage path of the connection channel 301 U-shaped, thereby improving the sealing performance of the connection channel 301.
[0059] Please see Figure 2 In some embodiments, the atomizing component 12 further includes a liquid storage cotton 122 disposed in the first liquid storage chamber 101. The liquid storage cotton 122 can wrap around the atomizing core 121. The liquid storage cotton 122 can absorb the aerosol matrix flowing out from the connecting channel 301. The liquid-coated cotton can absorb the aerosol matrix absorbed by the liquid storage cotton 122. The liquid storage cotton 122 plays a role in retaining and fixing the aerosol matrix, and at the same time, it can make the aerosol matrix evenly dispersed on the liquid-coated cotton, further reducing the risk of leakage. The liquid storage cotton 122 avoids the vent hole 1210 to reduce the resistance of external gas entering the first liquid storage chamber 101 through the vent hole 1210, and prevents the aerosol matrix on the liquid storage cotton 122 from blocking the vent hole 1210. The liquid storage cotton 122 covers at least part of the connecting channel 301 so that when the liquid storage tank 20 is compressed and deformed, the liquid storage cotton 122 can immediately absorb the aerosol matrix flowing into the first liquid storage chamber 101 from the connecting channel 301, reducing the possibility of the aerosol matrix blocking the vent 1210. The liquid storage cotton 122 may partially or completely cover the opening of the connecting channel 301; there is no limitation on this.
[0060] Optionally, a ventilation channel 105 is formed between the liquid storage cotton 122 and the bottom of the cavity wall of the first liquid storage chamber 101. Vent holes 1210 and connecting channels 301 are located at both ends of the ventilation channel 105 and are connected to the ventilation channel 105 so that external air can enter the second liquid storage chamber 201 through the ventilation channel 105.
[0061] Please see Figure 1 and Figure 2In some embodiments, the shell body 11 includes an outer shell 111 and a supporting shell 112. The outer shell 111 forms an installation cavity and a viewing hole 1110 communicating with the installation cavity. The supporting shell 112 is disposed in the installation cavity and forms a first liquid storage cavity 101. The supporting shell 112 covers the viewing hole 1110 and is able to transmit light. The amount of aerosol matrix absorbed in the liquid storage cotton 122 can be directly reflected in the appearance, such as color changes and changes in the obviousness of the pores of the liquid storage cotton 122. Therefore, after setting the viewing hole 1110, the user can observe the appearance of the liquid storage cotton 122 through the supporting shell 112 to understand the saturation level of the aerosol matrix in the liquid storage cotton 122. When the user observes that the aerosol matrix in the liquid storage cotton 122 is consumed in large quantities, the liquid storage cotton 122 can be replenished by pressing the end cap 22 of the liquid storage chamber 20.
[0062] Please see Figure 1 and Figure 2 In some embodiments, the atomizing chamber 10 further includes an air adjustment knob 60, and the outer shell 111 is also provided with an air inlet 106. The air inlet channel 102 is connected to the air inlet 106. The air adjustment knob 60 is slidably connected to the outer shell 111 and can slide between a first position and a second position. When the air adjustment knob 60 is in the first position, the air adjustment knob 60 blocks the air inlet. When the air adjustment knob 60 is in the second position, the air adjustment knob 60 avoids at least part of the air inlet 106. The user can adjust the air intake by adjusting the position of the air adjustment knob 60.
[0063] Please see Figure 2 and Figure 6 In some embodiments, the connecting channel 301 includes at least one liquid guiding hole 3011. The cross-sectional size of the liquid guiding hole 3011 can limit the flow of the aerosol matrix out of the liquid guiding hole 3011 under non-drive conditions. That is, the liquid guiding hole 3011 is also a microporous structure. Under non-drive conditions, if there is gas in the connecting channel 301, or if the aerosol matrix absorbed by the liquid storage cotton 122 has been largely consumed, causing the area near the connecting channel 301 to be filled with gas, the aerosol matrix in the second liquid storage chamber 201 will be retained at the opening of the liquid guiding hole 3011 or inside the liquid guiding hole 3011 due to its own surface tension. At this time, the user needs to press the end cap 22 to allow the aerosol matrix in the second liquid storage chamber 201 to quickly enter the first liquid storage chamber 101 through the liquid guiding hole 3011 to complete the replenishment. When no pressure is applied, if there is no gas in the liquid guiding hole 3011 and the aerosol matrix in the liquid guiding hole 3011 is connected to the aerosol matrix in the liquid storage cotton 122, then the aerosol matrix in the second liquid storage chamber 201 can enter the first liquid storage chamber 101 by siphoning, so as to achieve slow replenishment of the aerosol matrix.
[0064] Please see Figure 6 and Figure 7In some embodiments, the liquid guiding structure 30 further includes a liquid guiding plug 35 that is interference-fitted into the connecting channel 301. The peripheral sidewall of the liquid guiding plug 35 has multiple liquid guiding grooves 351, all extending axially along the liquid guiding plug 35. The groove wall of the liquid guiding groove 351 and the inner wall of the first connecting pipe 31 together form a liquid guiding hole 3011. The cross-sectional size of the liquid guiding hole 3011 allows the aerosol matrix to remain within the liquid guiding hole 3011 without pressure difference. Using the liquid guiding plug 35 to form the liquid guiding hole 3011 facilitates its installation and allows for the replacement of the appropriate liquid guiding plug 35 according to the required size. When the liquid guiding hole 3011 becomes clogged due to prolonged use of the atomizer, the liquid guiding plug 35 can be removed. The liquid guiding grooves 351 facilitate the cleaning of the liquid guiding plug 35.
[0065] Please see Figure 2 and Figure 6 In some embodiments, the liquid guiding structure 30 further includes a baffle 36, which is connected to the shell body 11 and covers the opening of the connecting channel 301. Specifically, the baffle 36 can cover the first connecting hole 104 and is integrally formed with the shell body 11. In other embodiments, the baffle 36 can also be connected to the liquid storage shell 21 and cover the second connecting hole 202, which is not limited here. The baffle 36 has at least one through hole 361 communicating with the first liquid storage cavity 101 and the connecting channel 301. The cross-sectional size of the through hole 361 can limit the aerosol matrix from flowing out of the through hole 361 under non-driving conditions, that is, the through hole 361 is also a microporous structure. The liquid guiding plug 35 is spaced apart from the baffle 36. In this way, after the user presses the end cap 22, the aerosol matrix in the second liquid storage chamber 201 can enter between the liquid guide plug 35 and the baffle 36 through the liquid guide hole 3011, and then enter the first liquid storage chamber 101 through the perforation 361. After the user releases the end cap 22, the gas in the atomization channel 120 can enter the second liquid storage chamber 201 through the vent hole 1210, the first liquid storage chamber 101, the perforation 361, and the connecting channel 301. The baffle 36 allows the aerosol matrix in the first liquid storage chamber 101 to seal the perforation 361 through its own surface tension when the atomization chamber 10 is used alone or when it needs to be assembled with the liquid storage chamber 20, thus preventing the aerosol matrix in the first liquid storage chamber 101 from leaking from the first connecting hole 104.
[0066] Optionally, multiple perforations 361 are provided. The liquid storage cotton 122 covers at least one perforation 361 and avoids at least one perforation 361. In this way, the gas in the atomization channel 120 can enter the first liquid storage chamber 101 through the vent 1210 and then directly enter the second liquid storage chamber 201 through the uncovered perforation 361. This avoids the aerosol matrix in the liquid storage cotton 122 from blocking the gas from entering the connecting channel 301. The aerosol matrix in the liquid storage cotton 122 can always be connected to the aerosol matrix in the connecting channel 301 through the perforation 361 it covers. This avoids the situation where liquid is discharged from a single hole and air is introduced from a single hole, which would block the communication between the aerosol matrix in the first liquid storage chamber 101 and the aerosol matrix in the second liquid storage chamber 201 when air is introduced.
[0067] Optionally, the connecting channel 301 also includes a shaft hole 3012 formed in the liquid guide plug 35. The shaft hole 3012 is formed along the axial direction of the liquid guide plug 35, and a plurality of liquid guide grooves 351 are arranged around the shaft hole 3012. The setting of the shaft hole 3012 can increase the flow rate and flow velocity of air that enters the connecting channel 301 through the through hole 361, and avoid the air intake speed being too slow due to the small cross-sectional area of the liquid guide hole 3011.
[0068] In other embodiments, the connecting channel 301 may not have a shaft hole 3012, but only a liquid guiding hole 3011, and there is no limitation here.
[0069] In the above embodiment, the atomizing chamber 10, the first connecting pipe 31, the third connecting pipe 33, the liquid guide plug 35, and the first sealing plug 40 together form the first part of the atomizer, and the liquid storage chamber 20, the second connecting pipe 32, the sealing ring 34, and the second sealing plug 50 together form the second part of the atomizer. In application, the first part and the second part can be sold and transported separately.
