[0037] The atomizer 2 in the present application may include a base 30, a first seal 40, a heating top cover 50, an atomizing assembly 60, a shell 70 and a second seal 80. Among them, the shell 70 has a liquid storage tank 10, an aerosol channel 90 and a receiving chamber (not shown in the figure), and the receiving chamber is connected to the liquid storage tank 10. The liquid storage tank 10 is arranged around the aerosol channel 90, and the liquid storage tank 10 is used to store the aerosol generating matrix. The base 30, the first seal 40 and the heating top cover 50 are all arranged in the receiving chamber to enclose the liquid storage chamber 10 with the shell 70. The first seal 40 is generally covered on one side of the base 30 close to the liquid storage tank 10 to form a seal on the base 30, so that the liquid storage tank 10 and the receiving chamber are isolated; the base 30 forms a support for the first seal 40. The heating top cover 50 is arranged on the side of the first sealing member 40 away from the base 30, and cooperates with the first sealing member 40 and the base 30 to form an atomizing chamber 61, and the atomizing chamber 61 is communicated with the aerosol channel 90. The atomizing assembly 60 is arranged on the side of the first sealing member 40 away from the base 30 and is at least partially located in the atomizing chamber 61, and is used to heat and atomize the aerosol generating matrix to form an aerosol when powered on, and a heating wire 62 for heating the aerosol generating matrix is ​​arranged on its surface. The heating top cover 50 also cooperates with the first sealing member 40 to fix the atomizing assembly 60. The second sealing member 80 is arranged between the heating top cover 50 and the aerosol channel 90, and is used to seal the connection between the two. One end of the housing 70 also has a suction port 72, and the suction port 72 is communicated with the aerosol channel 90, and the user inhales the aerosol atomized by the atomizing assembly 60 through the suction port 72.

[0038] The atomizer 2 also has a ventilation channel 20. The two ends of the ventilation channel 20 are connected to the outside atmosphere and the liquid storage tank 10, respectively, and the outside gas is introduced into the liquid storage tank 10 to avoid the liquid storage tank 10 being in an excessive negative pressure state, so as to achieve the air pressure balance between the liquid storage tank 10 and the outside atmosphere, so as to facilitate the aerosol generation matrix in the liquid storage tank 10 to be transported to the atomization component 60. The independently arranged ventilation channel 20 provided in the present application is arranged on the base assembly, directly connected to the liquid storage tank 10, and independently arranged from the lower liquid channel. The ventilation efficiency is high and suction leakage can be avoided. The ventilation channel 20 of the present application is described in detail below.

[0039] See also Figure 4-Figure 5 ,in, Figure 4 This is a structural schematic diagram of a first perspective of an embodiment of a base provided by the present application, Figure 5 A schematic diagram of the structure of an embodiment of the base provided by the present application from a second perspective. The ventilation channel 20 includes a first end 201 and a second end 202, wherein the first end 201 is connected to the outside of the atomizer 2, and the second end 202 is directly connected to the liquid storage tank 10. During the suction process, the air pressure balance between the liquid storage tank 10 and the atomization chamber 61 and / or the outside is adjusted to avoid the problem of burnt smell in the atomization assembly 60 due to insufficient liquid supply.

[0040] Specifically, in the present embodiment, the first end 201 of the ventilation channel 20 is directly connected to the outside of the atomizer 2, and the second end 202 is directly connected to the liquid storage tank 10. In the present embodiment, "directly connected to the outside of the atomizer 2" indicates that the ventilation channel 20 does not pass through the atomizing chamber 61, and "directly connected to the liquid storage tank 10" indicates that the ventilation channel 20 does not pass through the lower liquid channel. Therefore, the ventilation channel 20 is independently arranged and is only used to ventilate the liquid storage tank 10. In other embodiments, the first end 201 may also be connected to the outside atmosphere through other components of the atomizer 2, and the second end 202 may also be connected to the liquid storage tank 10 through the first sealing member 40 or other components, and the present application does not limit this, as long as the other components are not used for other fluid functions.

[0041] In one embodiment of the present application, the base 30 can form a ventilation channel 20 alone. Specifically, a first through hole (not shown) extending from the bottom of the base 30 to the top of the base 30 is provided on the side wall of the base 30, and the first through hole is entirely located in the side wall of the base 30. Therefore, it can be said that the ventilation channel 20 can be formed alone on the base 30 without the need to cooperate with other components.

[0042] In another embodiment of the present application, the first sealing member 40 is disposed on a side of the base 30 close to the liquid storage tank 10, and cooperates with the base 30 to form a ventilation channel 20. Specifically, the base 30 includes a base body 31 and a side wall 32, and the side wall 32 is formed by the base body 31 extending toward the surface of the liquid storage tank 10. The side wall 32 of the base 30 is provided with a ventilation groove 33, and the first sealing member 40 covers the ventilation groove 33 to form the ventilation channel 20. In this embodiment, the side wall 32 is formed by the base body 31 extending toward the surface of the liquid storage tank 10 and the positive projection of the base body 31 is a closed loop. In other embodiments, the side wall 32 may be only one or more support arms located at the base 30, and the support arms are also formed by the base body 31 extending toward the surface of the liquid storage tank 10, and the ventilation groove 33 may be arranged on the one or more support arms and enclosed with the first sealing member 40 to form the ventilation channel 20. It can be understood that the present application does not limit the shape, number, etc. of the side wall 32, and side walls or support arm structures similar to ventilation grooves are all included in the conceptual scope of the present application.

[0043] Continue reading Figure 4 The base 30 has a length direction and a width direction. Specifically, the base body 31 has a substantially rectangular or elliptical bottom surface. The length direction is along the long side of the rectangle or the long axis of the ellipse, and the width direction is along the short side of the rectangle or the short axis of the ellipse. In this embodiment, the ventilation channels 20 are distributed along the length direction of the base, and the number of ventilation channels 20 is 2, which are arranged at both ends along the length direction. In other embodiments, the position and number of ventilation channels 20 can be adjusted as needed, and as long as they have similar concepts to the present case, they should not be understood as limiting the scope of protection of this application.

[0044] In the present embodiment, the side wall 32 of the base 30 includes a side wall body 321 and a sink 322, and a receiving groove 3211 is provided on the inner surface of the side wall body 321. The sink 322 is arranged in the receiving groove 3211, and a ventilation groove 33 is provided on the sink 322. In the present embodiment, the ventilation groove 33 is provided on the side of the sink 322 close to the inner cavity of the base 30, so that the ventilation groove 33 extends from one end of the sink 322 close to the liquid storage tank 10 to the other end away from the liquid storage tank 10, and the first sealing member 40 covers the ventilation groove 33 to form a ventilation channel 20. In other embodiments, the ventilation groove 33 can also be provided in the center or other parts of the sink 322. As long as the ventilation groove 33 is provided on the sink 322, the effect of more convenient overall processing and manufacturing can be achieved, and the present application does not limit this. In other embodiments, the ventilation groove 33 can also be omitted, and the ventilation channel is formed by using the gap between the ventilation base and the receiving groove. The present application adopts a sink 322, which can facilitate production and processing on the one hand, and does not need to develop a new production mold for the base 30. It only needs to open a accommodating groove 3211 on the basis of the original base 30 mold, and then produce the structure of the sink 322 with the ventilation groove 33 separately, and the two can be matched and connected, which is convenient and fast, and can reduce production costs at the same time. On the other hand, the sink 322 can also be used as the ejector position of the base 30 mold, which is convenient for demolding and improves production efficiency. The base body 31 also has a connecting hole 38, and the ventilation channel 20 is connected to the outside of the atomizer 2 through the connecting hole 38. The size of the connecting hole 38 is adapted to the first end 201 of the ventilation channel 20 close to the base 30. In the present embodiment, the sink 322 is made of plastic material, and in other embodiments, other materials can also be used. The connecting hole 38 can be arranged on the bottom surface of the base body 31, and in other embodiments, the connecting hole 38 can also be arranged on the side of the base body 31, as long as it can be connected to the first end 201 of the ventilation channel 20. In addition, in other embodiments, the ventilation groove 33 can also be provided on the first seal 40, or the ventilation groove 33 can be provided on both the first seal 40 and the base 30, and the ventilation groove 33 on the first seal 40 and the ventilation groove 33 on the base 30 cooperate to form the ventilation channel 20, and the present application does not impose any restrictions on this.

[0045] Among them, one or more ventilation channels 20 can be provided, and the ventilation channel 20 can also be provided with a structure of one air outlet and multiple air inlets 36, as long as the two ends can be connected to the outside of the atomizer 2 and the liquid storage tank 10 respectively. In one embodiment, the base 30 has a length direction and a width direction, and the two ventilation channels 20 are symmetrically arranged at opposite ends of the base 30 along the length direction.

[0046] See also Figure 4-Figure 8 ,in, Figure 6 This is a structural schematic diagram from a first perspective of an embodiment of a first sealing member provided by the present application, Figure 7This is a schematic structural diagram from a second perspective of an embodiment of the first sealing member provided by the present application. Figure 8 A schematic structural diagram of a third perspective of an embodiment of a first sealing member provided in the present application.

[0047] In one embodiment, the first seal 40 includes a first seal body 41, a first protrusion 42, a second protrusion 43 and a boss 44. The first seal body 41 is covered on the base 30, and the first seal 40 is made of silicone material. On the basis of achieving connection with the heating top cover 50 and the base 30, the sealing performance can also be ensured. The first protrusion 42 is arranged on the surface of the first seal body 41 close to the base 30 and covers the ventilation groove 33 of the base 30, thereby forming a ventilation channel 20. The surface of the second protrusion 43 away from the first seal body 41 has a first groove 431, and the first groove 431 and the heating top cover 50 are surrounded to form an atomization chamber 61. Specifically, the second protrusion 43 has an annular side wall, and the annular side wall is surrounded to form the first groove 431. The opposite sides of the annular side wall have a first notch 4311, and the atomization assembly 60 is arranged in the atomization chamber 61 and the two ends of the atomization assembly 60 extend from the first notch 4311 respectively and are exposed in the liquid storage tank 10. The shape and size of the first notch 4311 match the outer surface of the atomizer assembly 60. When installed, the side wall of the first notch 4311 is arranged in close contact with the outer wall of the atomizer assembly 60. An extension portion 432 is further arranged on the side of the second protrusion 43 close to the heating top cover 50, and the extension portion 432 is matched and snap-fitted with the inner cavity of the heating top cover 50. Specifically, the extension portion 432 is arranged on the surface of the annular side wall of the second protrusion 43 away from the first sealing body 41 and has an opening corresponding to the first notch 4311.

[0048] In one embodiment, the side wall 32 of the base 30 is a closed side wall arranged in an annular shape, and supports the first sealing member 40. Specifically, the side wall 32 of the base 30 is arranged around the outside of the first protrusion 42 of the first sealing member 40, that is, the first protrusion 42 of the first sealing member 40 is inserted into the cavity surrounded by the annular side wall 32 of the base 30, and is matched and connected with the first protrusion 42, so as to support the first sealing member 40 as a whole.

[0049] In one embodiment, if Figure 6 As shown, a plurality of sealing ribs 411 are provided on the outer surface of the side wall of the first sealing body 41. The plurality of sealing ribs 411 are stacked and arranged around the outer surface of the side wall of the first sealing body 41. When the side wall 32 of the base 30 is connected, the sealing ribs 411 are supported to seal the connection between the base 30 and the first sealing member 40, thereby ensuring the sealing of the liquid storage tank 10 to prevent leakage.

[0050] The first seal 40 has a ventilation port 441 connected to the ventilation channel 20. Specifically, in one embodiment, a boss 44 is provided on the surface of the first seal body 41 away from the base 30, and a ventilation port 441 is provided on the boss 44, and the ventilation port 441 is connected to the ventilation groove 33. Specifically, the boss 44 extends toward the liquid storage tank 10 and is connected to the liquid storage tank 10, and the ventilation port 441 is provided on the surface of the boss 44, and the ventilation port 441 is connected to the ventilation groove 33, and then connected to the liquid storage tank 10. The atomizer assembly 60 is spaced apart from the boss 44, which can prevent the atomizer assembly 60 from blocking the ventilation port 441, and is conducive to the separation of bubbles in the ventilation port 441. If the atomizer assembly 60 is too close to or in contact with the boss 44, the bubbles in the ventilation port 441 are easily attached to the atomizer assembly 60. Specifically, in this embodiment, the boss 44 is disposed on both sides of the atomizing assembly 60, and the two sides of the atomizing assembly 60 are staggered with the ventilation ports 441 on the boss 44. The boss 44 is made of silicone material, which is convenient for connection and maintains sealing. In other embodiments, other materials may also be used.

[0051] In one embodiment, if Figure 3 and Figure 4 As shown, the path of the ventilation channel 20 can be straight or tortuous. In one embodiment, the ventilation channel 20 is configured to be tortuous, and the end of the sink 322 close to the liquid storage tank 10 is lower than the end of the side wall body 321 close to the liquid storage tank 10. Specifically, a certain gap 325 is left at the top of the sink 322, which is used to communicate with the ventilation groove 33 and the ventilation port 441, respectively, so as to form the ventilation channel 20. That is, the second end 202 of the ventilation groove 33 close to the first seal 40 is connected to the ventilation port 441 through the gap 325, and the ventilation channel 20 is bent in the direction of the sink 322 close to the first seal 40, that is, the ventilation channel 20 is axially arranged in the ventilation groove 33 part, and is bent in the horizontal direction in the part of the sink 322 close to the first seal 40, so that the ventilation groove 33 is connected with the ventilation port 441. In this embodiment, the height of the sink 322 is 0.2-0.3 mm lower than the height of the side wall body 321, so that the liquid storage tank 10 is not easy to leak, and at the same time, it can play a role in ventilation. In other embodiments, the ventilation port 441 can be set on the same line as the ventilation groove 33, and the ventilation port 441 is directly connected from the end of the ventilation groove 33 close to the ventilation port 441 to form a straight ventilation channel 20.

[0052] In one embodiment, if Figure 4 and Figure 8As shown, a first support portion 323 is provided on the top of the side wall 32 of the base 30, and the first support portion 323 and the sink 322 are located on different side walls of the side wall body 321, and are used to be clamped with the first seal 40. For example, the side wall body 321 includes two oppositely arranged long sides and two oppositely arranged short sides, the two sinks 322 are respectively arranged on the two oppositely arranged short sides, and the two first support portions 323 are respectively arranged on the two oppositely arranged long sides. A second support portion 324 is provided in the inner cavity of the base 30, the bottom end of the second support portion 324 is fixed on the surface of the base body 31 close to the first seal 40, and the top end extends toward the side close to the first seal 40, and the first support portion 323 and the second support portion 324 are correspondingly connected to the groove or slot inside the first seal 40. Specifically, the surface of the first seal 40 close to the base 30 has a third groove 433 matched with the second support portion 324. When connected, the second support portion 324 is inserted into the third groove 433 to achieve a tight connection with the first seal 40. A fourth groove 434 is formed between the first seal body 41 and the first protrusion 42, and the first support portion 323 is connected to the fourth groove 434 of the first seal 40, and is used to seal the connection between the base 30 and the first seal 40, so as to achieve a tight connection with the first seal 40. The number, size and shape of the first support portion 323 and the second support portion 324 can be set as needed, as long as they can achieve a matching connection with the third groove 433 and the fourth groove 434. The height of the first support portion 323 and the second support portion 324 can be set to be consistent or inconsistent, and this application does not limit this.

[0053] like Figures 2 to 4As shown, the inner surface of the base body 31 near the liquid storage tank 10 has a liquid storage tank 34, and the first end 201 of the ventilation channel 20 extends to the bottom of the liquid storage tank 34 and is connected to the liquid storage tank 34, so that the condensed liquid and the leaked atomized liquid can flow back to the reflux liquid storage tank 10 along the ventilation channel 20 while reducing the pressure of the liquid storage tank 10, thereby avoiding leakage. A first retaining portion 35 and an air inlet 36 are provided at the bottom of the inner cavity of the base 30, and the air inlet 36 is used for air intake. On the one hand, the gas entering from the air inlet 36 can enter the atomization chamber 61, carry the aerosol, and then enter the aerosol channel 90. On the other hand, the gas entering from the air inlet 36 can also enter the ventilation channel 20 through the connecting cavity 361 and the liquid storage tank 34 in sequence for ventilation. A second retaining portion 37 protruding from the air inlet 36 is provided around the air inlet 36, and the first retaining portion 35 and the second retaining portion 37 are used to lock the condensed liquid in the liquid storage tank 34 and the atomized liquid leaked from the liquid storage tank 10.
