[0010] The cavity wall connected to the second end of the liquid guide tube of the liquid storage cavity is provided with a capillary gas exchange channel, the capillary gas exchange channel making the hollow tube cavity and the external atmosphere in communication to supply gas to the container inner cavity through the hollow tube cavity.

[0011] In an embodiment, the width of the capillary gas exchange channel is 0.25mm-0.35mm, and the depth of the capillary gas exchange channel is 0.2mm-0.3mm.

[0012] In one embodiment, the shell comprises a blocking seat arranged on one side of the liquid storage cavity away from the first end of the liquid guide pipe, the blocking seat comprises a supporting seat and a sealing member, the capillary gas exchange channel is arranged on the surface of the supporting seat close to the liquid storage member, and the sealing member is arranged between the supporting seat and the liquid storage member to separate the liquid storage member from the capillary gas exchange channel.

[0013] In one embodiment, the supporting seat is provided with a fixed slot and a gas guide through hole side by side on the supporting seat, the sealing member is provided with a avoiding hole corresponding to the fixed slot, the second end of the liquid guide pipe is inserted into the fixed slot through the avoiding hole, the gas guide through hole penetrates through the supporting seat, the capillary gas exchange channel comprises a first channel part and a second channel part, the first channel part is arranged on the slot wall of the fixed slot and communicates with the hollow pipe cavity, and the second channel part is connected between the first channel part and the gas guide through hole, so that the first channel part communicates with the external atmosphere through the gas guide through hole.

[0014] In one embodiment, the blocking seat further comprises a bottom cover arranged on the side of the supporting seat away from the sealing member, the bottom cover and the supporting seat form a liquid suction cavity, the bottom cover is provided with an air inlet hole for communicating with the outside of the atomizer, and the liquid suction cavity communicates with the air inlet hole and the gas guide through hole; the atomizer further comprises a liquid suction member arranged in the liquid suction cavity corresponding to the gas guide through hole, for absorbing the liquid aerosol substrate entering the liquid suction cavity through the gas guide through hole.

[0015] In one embodiment, the atomizer further comprises a liquid guide column arranged in the hollow pipe cavity along the axial direction of the liquid guide pipe, the liquid guide column has a puncture end inserted into the container port, and the puncture end is used for piercing the interface of the liquid aerosol substrate to enable the liquid aerosol substrate to flow into the hollow pipe cavity.

[0016] In one embodiment, the side wall of the liquid guide column is provided with a capillary groove for guiding the flow of the liquid aerosol substrate.

[0017] In one embodiment, the material of the liquid guide column is plastic.

[0018] In one embodiment, the capillary groove is arranged on at least two sides of the liquid guide column.

[0019] According to the second aspect, in one embodiment, an atomizing device is provided, comprising:

[0020] a device shell;

[0023] According to the atomizer of the above embodiment, in one usage state, the liquid storage container can be in an inverted state with the container opening facing down, so that the liquid aerosol matrix in the inner cavity of the liquid storage container can be automatically transported to the liquid storage device under the action of gravity; by providing a liquid guide tube with a hollow cavity and a liquid guide hole, a liquid guide path is provided for the transfer of the liquid aerosol matrix in the inner cavity of the container to the liquid storage device, which helps to avoid excessive supply of liquid aerosol matrix to the liquid storage device.

[0024] As the liquid aerosol matrix enters the hollow tube cavity from the container's inner cavity, the air pressure inside the container gradually decreases, creating a negative pressure. This results in a pressure difference between the container's inner cavity and the hollow tube cavity, making it difficult for the liquid aerosol matrix to continue entering the hollow tube cavity. As the liquid aerosol matrix entering the hollow tube cavity is absorbed by the liquid storage device, the negative pressure in both the hollow tube cavity and the container's inner cavity continuously increases. However, by setting up a capillary ventilation channel connected to the external environment, when the negative pressure reaches the design value, outside air can overcome the capillary force of the capillary ventilation channel under pressure and enter the hollow tube cavity, supplementing the air pressure in the container's inner cavity. This maintains the air pressure balance in the hollow tube cavity and the container's inner cavity, facilitating the next round of liquid supply cycle. In other words, by utilizing the air guiding and capillary characteristics of the capillary ventilation channel, the pressure changes caused by the consumption of the liquid aerosol matrix during the atomizer's use are compensated, which helps to form a dynamic liquid supply cycle and achieve a stable supply of the liquid aerosol matrix.

[0037] The application will be further described in details through specific embodiments and with reference to the drawings. In different embodiments, similar elements are denoted by similar reference numerals. In the following embodiments, many details are described in order to make the application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by other elements, materials, methods. In some cases, some operations related to the application are not shown or described in the specification, in order to avoid the core of the application being overwhelmed by too much description, and it is not necessary for those skilled in the art to describe these related operations in detail according to the description in the specification and the general technical knowledge in the art.

[0038] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be sequentially adjusted or adjusted in a manner that is obvious to those skilled in the art. Therefore, the order in the specification and the drawings is only for the purpose of clearly describing a certain embodiment, and does not mean that it is the necessary order, unless otherwise stated that a certain order must be followed.

[0039] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling), unless otherwise specified.

[0040] Some atomizer products are equipped with a detachable liquid storage container 300 for storing liquid aerosol substrate. In use, the liquid storage container 300 supplies liquid to the liquid storage member 111 in the atomizer, and the liquid storage member 111 delivers the absorbed liquid aerosol substrate to the atomizing core 200 for heating and atomization by the atomizing core 200 to generate aerosol. A common problem with such atomizers is that if the liquid storage container 300 directly supplies liquid to the liquid storage member 111, it is easy to supply too much, resulting in product leakage; and if the liquid supply speed of the liquid storage container 300 is limited, it is easy to cause the consumption speed of the atomizing core 200 to be greater than the liquid supply speed of the liquid storage container 300, causing the atomizing core 200 to dry out and cause the wick to burn out.

[0041] In the embodiments of the present application, by providing a liquid guide pipe 400 with a hollow lumen 410 and a liquid guide through hole 420 in the atomizer, a liquid guide path is provided for the transmission of liquid aerosol substrate in the container inner cavity 310 to the liquid storage member 111, which helps to avoid over-supplying liquid aerosol substrate to the liquid storage member 111. In order to avoid the atomizing core 200 from drying out and burning out the wick, a capillary air exchange passage 500 is provided to communicate the hollow lumen 410 with the external environment, and the capillary air exchange passage 500 has air guiding and capillary properties. The capillary air exchange passage 500 can cooperate with the liquid guide pipe 400 to establish a dynamic liquid supply circulation, compensate for changes in air pressure caused by the consumption of liquid aerosol substrate during use of the atomizer, and avoid the influence of the liquid supply speed, which helps to achieve stable supply of liquid aerosol substrate.

[0042] Embodiments of the atomizer in the present application:

[0043] In one embodiment, please refer to Figures 1-4 The atomizer includes a housing 100, a liquid storage member 111, a liquid storage container 300, a liquid guide pipe 400, and an atomizing core 200.

[0044] The housing 100 can be understood as a collection of related components that constitute the basic structural framework and outer contour form of the atomizer, and the atomizer can be held, moved, operated and used with the help of the housing 100. In one embodiment, please refer to Figure 1 and Figure 2 The housing 100 has a liquid storage cavity 110, and the liquid storage member 111 is arranged in the liquid storage cavity 110. The liquid storage member 111 can be liquid storage cotton, liquid storage block, liquid storage fiber or other elements capable of storing liquid aerosol substrate. The atomizing core 200 can be arranged to be wrapped in the liquid storage member 111, so that the liquid aerosol substrate absorbed by the liquid storage member 111 can be supplied to the atomizing core 200.

[0045] Exemplarily, please refer to Figure 1 and Figure 2, the shell 100 is a long strip structure with a length direction, the liquid storage cavity 110 is arranged at one side of the shell 100 in the length direction, the liquid storage piece 111 is arranged in the liquid storage cavity 110, the liquid storage cavity 110 can be provided with the atomizing pipe 210 along the length direction of the shell 100, the atomizing pipe 210 is at least partially embedded in the liquid storage piece 111, the atomizing core 200 is arranged in the inner cavity of the part of the atomizing pipe 210 in the liquid storage piece 111, and the liquid inlet hole is arranged on the pipe wall of the atomizing pipe 210 corresponding to the atomizing core 200. The liquid aerosol substrate absorbed in the liquid storage piece 111 can be inhaled into the atomizing core 200 through the liquid inlet hole and atomized under the heating of the atomizing core 200. With the liquid aerosol substrate in the liquid storage piece 111 near the atomizing core 200 being absorbed, atomized and discharged, the liquid aerosol substrate in other areas of the liquid storage piece 111 will migrate to the vicinity of the atomizing core 200 to continuously supply the liquid aerosol substrate to the atomizing core 200.

[0046] The liquid storage container 300 can be understood as a supply source of the liquid aerosol substrate in the atomizer. In an embodiment, referring to Figure 1 and Figure 2 , the liquid storage container 300 has a container inner cavity 310 and a container port 320 in communication with each other, the container inner cavity 310 is used for storing the liquid aerosol substrate, and the container port 320 is used for discharging the liquid aerosol substrate in the container inner cavity 310. According to the design and use needs of the atomizer, the liquid storage container 300 can be configured to be detachably mounted on the shell 100, so as to realize the replenishment of the liquid aerosol substrate by replacing the liquid storage container 300, or can be integrated with other components in the atomizer.

[0047] Those skilled in the art can understand that the atomizer can be designed to be in an inverted state with the container port 320 downward when in use, so that the liquid aerosol substrate in the liquid storage container 300 can be automatically discharged under the action of gravity.

[0048] In order to facilitate the use of the atomizer in the state that the liquid storage container 300 automatically supplies liquid by relying on gravity, in an embodiment, referring to Figure 1 and Figure 2 , the shell 100 has a mounting cavity 120 for mounting the liquid storage container 300, the mounting cavity 120 has a mounting port 121 on the side away from the liquid storage cavity 110, and the cavity wall of the mounting cavity 120 on the side close to the liquid storage cavity 110 is provided with a connecting port 122 for connecting the container port 320; the shell 100 has a mouthpiece setting position arranged side by side with the mounting port 121. By arranging the mouthpiece setting position and the mounting port 121 side by side, the liquid storage container 300 can naturally be in an inverted state with the container port 320 downward when being sucked, which is helpful to realize automatic liquid supply.

[0049] Exemplarily, referring to Figure 1 and Figure 2The installation cavity 120 is arranged at one end of the shell 100 along the length direction, the installation port 121 is arranged on the end wall of the shell 100, the liquid storage cavity 110 is arranged on the side of the installation cavity 120 away from the installation port 121 and is arranged separately from the installation cavity 120, the connecting port 122 is arranged on the cavity wall between the liquid storage cavity 110 and the installation cavity 120 to communicate the liquid storage cavity 110 and the installation cavity 120, the connecting port 122 can be inserted by the container port 320, and a sealing ring can be arranged in the connecting port 122 to fix the container port 320. The suction nozzle is arranged side by side with the installation port 121, and the suction nozzle arrangement position can be opposite to the atomizing pipe 210.

[0050] In other embodiments, the installation cavity 120 can be cancelled, and the liquid storage container 300 is directly installed on the liquid storage cavity 110 in a detachable or non-detachable manner.

[0051] The above-mentioned gravity drainage method can automatically drain liquid, but the drainage amount is difficult to control, and the liquid storage container 300 is prone to excessive supply, which causes the atomizer to leak. Therefore, the liquid supply amount of the liquid storage container 300 needs to be controlled, and the liquid supply amount of the liquid storage container 300 can be controlled by limiting the liquid guide path between the liquid storage container 300 and the liquid storage member 111.

[0052] The liquid guide pipe 400 can be understood as a structure for limiting the liquid guide path between the liquid storage container 300 and the liquid storage member 111. In one embodiment, referring to Figure 1 and Figure 2 The liquid guide pipe 400 has a hollow pipe cavity 410 and has a first end and a second end along the axial direction. The second end of the liquid guide pipe 400 is arranged in the liquid storage cavity 110 and connected with the cavity wall of the liquid storage cavity 110. The first end of the liquid guide pipe 400 is inserted into the container port 320 to make the inner cavity 310 of the container and the hollow pipe cavity 410 liquidly communicated. The second end of the liquid guide pipe 400 is connected with the cavity wall of the liquid storage cavity 110 in the form of insertion, adhesion, welding or other connection modes. The liquid guide through hole 420 is arranged on the pipe wall inside the liquid storage cavity 110 to make the hollow pipe cavity 410 and the liquid storage cavity 110 liquidly communicated, so that the liquid aerosol substrate in the liquid storage container 300 can be transported to the liquid storage member 111 through the liquid guide pipe 400.

[0053] By arranging the liquid guide pipe 400, the hollow inner cavity of the liquid guide pipe 400 forms a transfer liquid guide path of the liquid aerosol substrate, so that the maximum speed of the liquid supply to the liquid storage member 111 is limited by the specifications of the hollow inner cavity and the liquid guide through hole 420, which helps to avoid the liquid storage container 300 from supplying too much liquid to the liquid storage member 111.

[0054] Exemplarily, referring to Figure 1 and Figure 2The liquid guide pipe 400 is arranged side by side along the length direction of the shell 100 on one side of the atomizing pipe 210, the first end of the liquid guide pipe 400 is the upper end of the liquid guide pipe 400 in the view angle shown in the figure, the second end of the liquid guide pipe 400 is the lower end of the liquid guide pipe 400, the second end of the liquid guide pipe 400 is connected with the cavity wall on the side of the liquid storage cavity 110 away from the mounting cavity 120, the first end of the liquid guide pipe 400 is inserted into the container port 320 through the connecting port 122, the liquid guide through hole 420 is arranged on the pipe wall of the liquid guide pipe 400 inside the liquid storage cavity 110, and a plurality of liquid guide through holes 420 can be arranged along the circumference of the liquid guide pipe 400, so as to discharge the liquid from the liquid storage member 111. Figure 1 The second end of the liquid guide pipe 400 is the lower end of the liquid guide pipe 400, the second end of the liquid guide pipe 400 is connected with the cavity wall on the side of the liquid storage cavity 110 away from the mounting cavity 120, the first end of the liquid guide pipe 400 is inserted into the container port 320 through the connecting port 122, the liquid guide through hole 420 is arranged on the pipe wall of the liquid guide pipe 400 inside the liquid storage cavity 110, and a plurality of liquid guide through holes 420 can be arranged along the circumference of the liquid guide pipe 400, so as to discharge the liquid from the liquid storage member 111.

[0055] After the liquid aerosol substrate is discharged by the liquid guide through hole 420, the part of the liquid storage member 111 outside the liquid guide through hole 420 absorbs the liquid, which is easy to produce a sealing effect similar to a liquid seal on the liquid guide through hole 420, so that it is difficult for the gas in the hollow inner cavity to be discharged from the liquid guide through hole 420. As the liquid aerosol substrate in the container inner cavity 310 enters the hollow pipe cavity 410, the gas pressure in the container inner cavity 310 will gradually decrease to produce negative pressure, and then the pressure difference between the container inner cavity 310 and the hollow pipe cavity 410 is generated, which makes it difficult for the liquid aerosol substrate to continue to enter the hollow pipe cavity 410, affecting the stability of the liquid discharge of the liquid storage member 111.

[0056] To this end, in one embodiment, please refer to Figure 2 and Figure 3 A capillary gas exchange channel 500 is arranged on the cavity wall of the liquid storage cavity 110 connected with the second end of the liquid guide pipe 400, and the capillary gas exchange channel 500 connects the hollow pipe cavity 410 with the external atmosphere. During the use of the atomizer, as the liquid aerosol substrate that has entered the hollow pipe cavity 410 is absorbed by the liquid storage member 111, the negative pressure in the hollow pipe cavity 410 and the container inner cavity 310 will continuously increase, and when the negative pressure reaches the designed value, the external air can enter the hollow pipe cavity 410 and the container inner cavity 310 to supplement the gas pressure under the action of pressure, so as to maintain the balance of the gas pressure in the hollow pipe cavity 410 and the container inner cavity 310, so that the liquid aerosol substrate in the liquid storage cavity 110 can continue to be transported to the hollow pipe cavity 410, and then the above process is repeated to perform the next round of liquid supply circulation.

[0057] By setting the capillary air exchange channel 500, the fluid can be able to overcome the capillary force to pass through the capillary air exchange channel 500, so that the gas in the external environment can enter the hollow lumen 410 in the liquid supply process by using the pressure difference to overcome the capillary force, to supply gas to the container cavity 310 through the hollow lumen 410, to compensate for the pressure difference generated by the liquid discharge; and the liquid aerosol substrate in the hollow lumen 410 is difficult to overcome the capillary force to discharge through the capillary air exchange channel 500, which helps to improve the stability of liquid discharge while avoiding the risk of liquid leakage.

[0058] In some embodiments, the width of the capillary air exchange channel 500 can be 0.25mm-0.35mm; for example, 0.25mm, 0.3mm or 0.35mm, etc. The depth of the capillary air exchange channel 500 can be 0.2mm-0.3mm; for example, 0.2mm, 0.25mm or 0.3mm, etc.

[0059] Exemplarily, the capillary air exchange channel 500 can be configured to be 0.3mm wide and 0.25mm deep, so that the gas passing through the capillary air exchange channel 500 requires an action force of about 1000Pa provided by the pressure difference. The liquid storage container 300 can be configured such that when the internal pressure of the container cavity 310 is substantially-500Pa, the liquid aerosol substrate in the container cavity 310 is difficult to be discharged automatically under the action of gravity.

[0060] When the internal pressure of the container cavity 310 reaches about-500Pa, as the liquid aerosol substrate in the hollow lumen 410 is absorbed by the liquid storage member 111, the pressure in the hollow lumen 410 gradually decreases, and the liquid aerosol substrate in the container cavity 310 can continue to be discharged under the action of the pressure difference, while the negative pressure in the container cavity 310 is constantly increased from about-500Pa, and when it reaches about-1000Pa, the gas in the external environment enters the hollow lumen 410 from the capillary air exchange channel 500, and then enters the liquid storage container 300, to supplement the gas in the container cavity 310, so that the pressure in the container cavity 310 returns to about-500Pa, and a new round of liquid supply cycle is continued.

[0061] Those skilled in the art can understand that in some embodiments, the capillary air exchange channel 500 can be provided on the surface of the cavity wall connecting the liquid storage cavity 110 and the second end of the liquid guide pipe 400; in other embodiments, the capillary air exchange channel 500 can also be provided inside the cavity wall connecting the liquid storage cavity 110 and the second end of the liquid guide pipe 400, which can make the hollow lumen 410 and the external environment gas communicate.

[0062] In one embodiment, please refer to Figure 2 and Figure 3The housing 100 includes a sealing seat 130 disposed on the side of the liquid storage chamber 110 away from the first end of the liquid guide tube 400. The sealing seat 130 includes a support 131 and a sealing element 132. A capillary ventilation channel 500 is disposed on the surface of the support 131 near the liquid storage element 111. The sealing element 132 is disposed between the support 131 and the liquid storage element 111 to isolate the liquid storage element 111 from the capillary ventilation channel 500. This helps to prevent the liquid aerosol matrix in the liquid storage element 111 from entering the capillary ventilation channel 500 during use, which is beneficial for maintaining a stable gas supply. Those skilled in the art will understand that the shape of the sealing element 132 can be set with reference to the cross-sectional contour shape of the liquid storage chamber 110 so that the sealing element 132 can also seal the assembly gap between the housing 100 and the support 131, reducing the risk of leakage of the atomizer.

[0063] In one embodiment, please refer to Figure 2 and Figure 3 The support base 131 can be provided with a fixed slot 1311 and a vent hole 1312 side by side. The sealing element 132 is provided with a clearance hole 1321 corresponding to the fixed slot 1311. The second end of the liquid guide tube 400 passes through the clearance hole 1321 and is inserted into the fixed slot 1311, which facilitates the positioning of the liquid guide tube 400 and the assembly of the liquid guide tube 400. The vent hole 1312 passes through the support base 131. The capillary ventilation channel 500 includes a first channel part 510 and a second channel part 520. The first channel part 510 is provided on the groove wall of the fixed slot 1311 and communicates with the hollow tube cavity 410. The second channel part 520 is connected between the first channel part 510 and the vent hole 1312, so that the first channel part 510 communicates with the external atmospheric gas through the vent hole 1312.

[0064] For example, please refer to Figure 2 and Figure 3 A ventilator hole 1312 is provided on both sides of the fixed slot 1311 on the support base 131. The ventilator hole 1312 extends through the support base 131 along the length of the housing 100. The opening of one side of the ventilator hole 1312 faces the seal 132, and the opening of the other side is provided on the surface of the support base 131 away from the seal 132. A capillary ventilation channel 500 is provided on the surface of the support base 131 near the seal 132, and two sets are provided corresponding to the ventilator hole 1312. The second channel portion 520 is provided between the corresponding ventilator hole 1312 and the fixed slot 1311, and the first channel portion 510 is provided on the groove wall of the fixed slot 1311. A part of the first channel portion 510 is provided on the side wall of the fixed slot 1311, and another part is provided on the bottom wall of the fixed slot 1311, so as to connect the second channel portion 520 and the hollow cavity 410.

[0065] The sealing member 132 can also have a protrusion 1322 protruding in the fixing slot 1311, and the avoiding hole 1321 penetrates the protrusion 1322 and the part of the sealing member 132 corresponding to the protrusion 1322 along the axial direction of the liquid guide pipe 400, so as to cooperate with the fixing slot 1311 to fix the second end of the liquid guide pipe 400. The sealing member 132 and the support base 131 can be provided with an assembly channel corresponding to the atomizing pipe 210, so as to install and fix the atomizing pipe 210.

[0066] In an embodiment, referring to Figure 1 and Figure 2 The blocking seat 130 further comprises a bottom cover 133, which is arranged on the side of the support base 131 away from the sealing member 132. The bottom cover 133 and the support base 131 form a liquid suction cavity 134. The bottom cover 133 is provided with an air inlet hole 1331 for communicating with the atmosphere outside the atomizer. The liquid suction cavity 134 is in communication with the air inlet hole 1331 and the air guide through hole 1312. The atomizer further comprises a liquid suction member 1341 arranged in the liquid suction cavity 134 corresponding to the air guide through hole 1312, such as being arranged directly below the air guide through hole 1312 in the perspective view shown in Figure 2 The liquid suction member 1341 is used to absorb the liquid aerosol substrate entering the liquid suction cavity 134 through the air guide through hole 1312, so as to prevent the liquid aerosol substrate from leaking through the air guide through hole 1312.

[0067] In addition, due to the volume limitation of the atomizer, the inner diameter of the liquid guide pipe 400 is usually small, which causes the interface of the liquid aerosol substrate contacting with the gas to form a liquid film under the influence of surface tension after the liquid aerosol substrate enters the hollow pipe cavity 410, so that the liquid aerosol substrate is difficult to flow downward. Therefore, in an embodiment, referring to Figures 1-3 The atomizer further comprises a liquid guide column 600 arranged in the hollow pipe cavity 410 along the axial direction of the liquid guide pipe 400. The liquid guide column 600 has a puncture end 611 inserted into the container port 320, which is used to pierce the interface of the liquid aerosol substrate, so that the liquid aerosol substrate can flow into the hollow pipe cavity 410. By arranging the liquid guide column 600, the liquid film formed by piercing the interface of the liquid aerosol substrate can help to transport the liquid aerosol substrate.

[0068] Exemplarily, the liquid guide column 600 can be integrally arranged on the support base 131 and extended along the axial direction of the liquid guide column 600 by the bottom wall of the fixing slot 1311. The puncture end 611 of the liquid guide column 600 can be located at the first end of the liquid guide pipe 400 and inserted into the container port 320 together with the liquid guide pipe 400. In other embodiments, the liquid guide column 600 can also be fixedly arranged on the pipe wall of the liquid guide pipe 400, which can meet the design and use requirements.

[0069] In an embodiment, referring to Figure 2 andFigure 3 The side wall of the liquid guide column 600 is provided with a capillary groove 640 for guiding the flow of liquid aerosol substrate, which facilitates the further flow of liquid aerosol substrate to the direction close to the liquid guide through hole 420, and helps to control the liquid supply speed to remain within a suitable range. Exemplarily, the capillary groove 640 is a linear groove arranged along the axial direction of the liquid guide column 600. In other embodiments, the capillary groove 640 can also be designed as a spiral shape, a wave shape or other shapes. The width of the capillary groove 640 can be 0.25mm-0.35mm; for example, 0.25mm, 0.3mm or 0.35mm, etc. The depth of the capillary groove 640 can be 0.2mm-0.3mm; for example, 0.2mm, 0.25mm or 0.3mm, etc.

[0070] In an embodiment, referring to Figure 2 and Figure 3 The capillary groove 640 can be arranged with at least two on the circumferential side of the liquid guide column 600 to cooperate and play a role, which helps to strengthen the control effect of the liquid supply speed and improve the stability of liquid guiding.

[0071] In a further embodiment, the material of the liquid guide column 600 can be plastic, which has better dimensional stability than silica gel, cotton stick and other materials, which is beneficial to maintain a small processing tolerance and facilitate the processing of qualified capillary grooves 640. In other embodiments, the liquid guide column 600 can also use other materials that meet the design and use requirements.

[0072] In an embodiment, referring to Figure 2 and Figure 3 The end of the liquid guide column 600 away from the puncture end 611 has a sealing section 620, and the outer peripheral surface of the sealing section 620 is attached to the inner wall of the liquid guide tube 400; the capillary groove 640 passes through the sealing section 620 and is in fluid communication with the capillary gas exchange channel 500. By providing the sealing section 620, it helps to seal the second end of the liquid guide tube 400 to a certain extent, so as to reduce the risk of leakage of liquid aerosol substrate from the second end of the liquid guide tube 400. By arranging the capillary groove 640 to pass through the sealing section 620 and the capillary gas exchange channel 500, on the one hand, it helps to maintain the communication between the capillary gas exchange channel 500 and the hollow tube cavity 410, and on the other hand, it helps the external gas to enter the container inner cavity 310 through the capillary groove 640, which is beneficial to maintain the stability of the liquid supply circulation.

[0073] In an embodiment, referring to Figure 1 and Figure 2The liquid guiding through hole 420 is located at the middle of the liquid storage member 111 along the axial direction of the liquid guiding pipe 400. The liquid guiding column 600 is provided with a space occupying section 630 on the side of the sealing section 620 close to the liquid guiding through hole 420. The outer diameter of the space occupying section 630 is smaller than the inner diameter of the liquid guiding pipe 400. The space occupying section 630 is used to reduce the storage space of the liquid aerosol substrate between the sealing section 620 and the liquid guiding through hole 420.

[0074] The setting position of the liquid guiding through hole 420 helps the liquid storage member 111 to fully absorb the aerosol substrate, which is beneficial to avoid dry burning of the atomizer core 200. The space occupying section 630 is not only helpful to reduce the accumulation of the liquid aerosol substrate between the sealing section 620 and the liquid guiding through hole 420, but also does not easily increase the assembly difficulty of the liquid guiding column 600 and the liquid guiding pipe 400.

[0075] In an embodiment, please refer to Figure 3 The side of the liquid guiding column 600 away from the sealing section 620 is called the liquid guiding section 610. The part of the capillary groove 640 on the space occupying section 630 and the part on the liquid guiding section 610 can be provided in a segmented manner without being connected, which is helpful for the liquid aerosol substrate to be discharged through the liquid guiding through hole 420 after passing through the part of the capillary groove 640 on the space occupying section 630. The width of the part of the capillary groove 640 on the liquid guiding section 610 can be not greater than the width of the part on the space occupying section 630.

[0076] In an embodiment, please refer to Figure 1 and Figure 2 The liquid storage container 300 can be detachably assembled in the shell 100. In order to facilitate the inverted installation of the liquid storage container 300, a sealing valve 330 can be arranged at the container port 320, and a liquid guiding gap 430 can be arranged at the first end of the liquid guiding pipe 400. When the liquid storage container 300 is assembled in the shell 100, the first end of the liquid guiding pipe 400 pushes the sealing valve 330 to an open state, so that the container inner cavity 310 and the hollow pipe cavity 410 are communicated through the liquid guiding gap 430.

[0077] Exemplarily, please refer to Figure 1 and Figure 2The sealing valve 330 comprises a valve body 331, a valve core 332 and an elastic member 333. The valve body 331 is fixedly arranged in the inner cavity 310 of the container. The valve core 332 is arranged on the valve body 331 in a sliding manner along the axial direction of the container port 320 and faces the container port 320. An end of the valve core 332 close to the container port 320 is provided with a plug. The plug can be inserted into the container port 320 to seal the container port 320. A sealing ring is arranged on the plug. The elastic member 333 is arranged between the valve core 332 and the valve body 331. The elastic member 333 is used to apply an elastic force to the valve core 332 in a direction close to the container port 320, which helps to avoid accidental opening of the valve core 332. When the liquid storage container 300 is disassembled, the valve core 332 can automatically seal the container port 320. The elastic member 333 can be a spring, an elastic rubber pad, a spring leaf or other elastic structural members that can generate an elastic force meeting the design requirements.

[0078] The first end of the liquid guide pipe 400 can be inserted into the inner cavity 310 of the container through the container port 320 during assembly of the liquid storage container 300, so as to push the plug part of the valve core 332 into the inner cavity 310 of the container, so that the inner cavity 310 of the container and the hollow pipe cavity 410 are communicated through the liquid guide gap 430.

[0079] In other embodiments in which the liquid storage container 300 is detachably assembled in the shell 100, the sealing valve 330 can also adopt other structures that can meet the design and use requirements. The sealing valve 330 arranged on the container port 320 can also be cancelled. When the liquid storage container 300 needs to be installed or replaced, the atomizer can be inverted so that the container port 320 of the liquid storage container 300 faces upward and then the installation or replacement is performed.
