[0048] The present application is based on the technical problem that the concentration of atomized aerosol gradually decreases when an aerosol atomization device is in use, and provides an atomization device and an atomization device. The atomization device includes a liquid storage component, an atomization component and an adsorbent; the liquid storage component can be divided into a first cavity and a second cavity, the adsorbent is accommodated in the first cavity of the liquid storage cavity, and is used to adsorb and store part of the liquid aerosol generating matrix in the liquid storage cavity, and a liquid storage interval is formed between the bottom surface of the adsorbent and the liquid surface formed by the aerosol generating matrix in the second cavity; when the user does not inhale and use the atomization device, and the atomization device is placed horizontally or upside down, the liquid aerosol generating matrix in the second cavity flows to the adsorbent, and the aerosol generating matrix is ​​replenished for the adsorbent, so that the capacity of the aerosol generating matrix in the adsorbent remains stable during each inhalation, thereby achieving stable liquid supply to the atomization component, effectively ensuring the stability of the aerosol concentration generated by atomization when the atomization device is in normal use, and achieving a stable taste before and after the atomization device is used; for details, please refer to the following embodiments.

[0049] See also Figure 1 In one embodiment of the present application, an atomizing device 1000 is provided, including an atomizing device 100, which is a main functional component in the atomizing device 1000, and heats and atomizes a liquid aerosol-generating substrate to generate an aerosol. The atomizing device 100 includes a liquid storage component 10, an atomizing component 20, and an adsorbent 30.

[0050] The liquid storage component 10 is provided with a liquid storage cavity 101 for storing a liquid aerosol generating matrix, and the liquid storage cavity 101 can be divided into two parts, a first cavity 1011 and a second cavity 1012. Among them, the first cavity 1011 and the second cavity 1012 are arranged and connected along a preset direction, and the preset direction can be the height direction when the atomizing device 1000 is in use, that is, the first cavity 1011 and the second cavity 1012 are distributed along the height direction. In this embodiment, when the atomizing device 1000 is in use, the first cavity 1011 can be located above the second cavity 1012.

[0051] The adsorbent 30 is accommodated in the first cavity 1011 of the liquid storage cavity 101, and is used to absorb and store part of the liquid aerosol generating matrix in the liquid storage cavity 101. The atomizing component 20 is inserted into the adsorbent 30, and is used to absorb and heat the aerosol generating matrix in the adsorbent 30 to generate aerosol by atomization. The adsorbent 30 is arranged to fit the outer periphery of the atomizing component 20. On the one hand, it guides the liquid aerosol generating matrix to the atomizing component 20, supplies liquid to the atomizing component 20, and ensures that the atomizing component generates aerosol by atomization normally. On the other hand, it is used to lock the position of the adsorbent 30 relative to the liquid storage cavity 101 to prevent the adsorbent 30 from sliding toward the second cavity 1012.

[0052] The aerosol generating matrix in the liquid storage chamber 101 away from the adsorbent 30 is filled in part of the second cavity 1012, and a liquid storage interval 1010 is formed between the liquid surface formed by the aerosol generating matrix in the second cavity 1012 and the adsorbent 30. When the user normally inhales and uses the atomizing device 1000, the suction nozzle 40 of the atomizing device 1000 faces upward, and the atomizing assembly 20 is below the suction nozzle 40. The liquid aerosol generating matrix in the liquid storage chamber 101 is located in the second cavity 1012 under the action of gravity, and forms a liquid storage interval 1010 with the bottom surface of the adsorbent 30. At this time, the adsorbent 30 is not in contact with the aerosol generating matrix in the second cavity 1012.

[0053] When the aerosol generating matrix in the adsorption component 30 is consumed and the user is not using the atomizing device 1000 for inhalation, the atomizing device 1000 may be placed horizontally, upside down or in other abnormal positions during the process of being carried, so that the liquid aerosol generating matrix in the second cavity 1012 will flow to the adsorption component 30, and the adsorption component 30 will adsorb and fix the aerosol generating matrix until it is saturated. The aerosol generating matrix exceeding the saturated state falls into the second cavity 1012, so that the capacity of the aerosol generating matrix in the adsorption component 30 is maintained at a reasonable state during each inhalation, thereby achieving stable liquid supply to the atomizing component 20, effectively ensuring the stability of the aerosol concentration generated by atomization when the atomizing device 1000 is used normally, and achieving a stable taste before and after the use of the atomizing device 1000.

[0054] In addition, when the aerosol generating matrix in the adsorbent 30 is consumed and is lower than a reasonable state, the aerosol generating matrix in the second cavity 1012 can be replenished into the adsorbent by inverting or tilting, thereby achieving a stable taste before and after use of the atomizing device 1000.

[0055] Considering that some aerosol atomization devices use liquid storage cotton to absorb and store liquid aerosol generating matrix, as the aerosol atomization device is continuously pumped, the amount of liquid stored in the liquid storage cotton decreases, causing the concentration of liquid aerosol generating matrix in the liquid storage cotton to continuously decrease, which in turn causes the aerosol atomization device to have inconsistent tastes. In addition, during the shelf storage period of the aerosol atomization device, the liquid storage cotton fibers absorb certain ingredients such as flavors and sweeteners in the liquid aerosol generating matrix, which will cause the taste to become lighter.

[0056] In the present application, part of the liquid aerosol generating matrix is ​​stored in the adsorbent 30 in the first cavity 1011, and the other part is stored in the second cavity 1012. When the atomizing device 1000 is placed vertically (that is, the first cavity 1011 is on top and the second cavity 1012 is on the bottom), the liquid aerosol generating matrix that is overflowing or overloaded in the adsorbent 30 can enter the second cavity 1012 under the action of gravity. When the atomizing device 1000 is in a non-vertical state (for example, placed horizontally, sideways, flat, tilted or inverted), the liquid aerosol generating matrix in the second cavity 1012 can enter the first cavity 1011 and then be adsorbed by the adsorbent 30, replenishing the aerosol generating matrix in the adsorbent 30, and the concentration of the liquid aerosol generating matrix in the adsorbent 30 remains stable, thereby ensuring that the taste of the atomizing device 1000 is consistent before and after. Through the above method, the problem of too little oil in the inverted adsorption part 30 of the atomizing device 1000 during long-term storage and the consistent taste of the atomizing device 1000 before and after can be solved, thereby improving the user experience.

[0057] In addition, in the existing aerosol atomization equipment, liquid storage cotton is used to absorb and store liquid aerosol generating matrix, and the volume of liquid aerosol generating matrix absorbed by liquid storage cotton only accounts for 80% of the volume occupied by oil storage cotton. In other words, 10ml of liquid storage space can only store 8.5ml of liquid aerosol generating matrix at most in the presence of liquid storage cotton. And in the atomization equipment using liquid storage cotton to absorb and store liquid aerosol generating matrix, when the content of liquid aerosol generating matrix in oil storage cotton is lower than 15% (the residual oil rate is usually as high as 15% or more), the liquid aerosol generating matrix cannot be effectively introduced into the atomization component to cause dry burning, that is, at least 15% of the liquid aerosol generating matrix in the oil storage cotton cannot be effectively utilized. By calculation: [10ml*80%*(1-15%)] / 10ml=68%, the liquid aerosol generating matrix that can be effectively utilized in the liquid storage space only accounts for 68% of the volume of the liquid storage space.

[0058] However, when the atomizer component is directly immersed in the liquid aerosol generating matrix in the liquid storage chamber, although the proportion of the liquid aerosol generating matrix that can be effectively utilized in the liquid storage space can be increased, there is a problem of overload and penetration of the atomizer component, which causes leakage of the atomizer component and affects the reliability of the atomizer equipment.

[0059] The present device can effectively increase the volume ratio of the liquid aerosol generating matrix that can be effectively utilized in the liquid storage chamber 101 by dividing the liquid storage chamber 101 into a first cavity 1011 and a second cavity 1012, wherein part of the liquid aerosol generating matrix is ​​stored in the adsorbent 30 in the first cavity 1011 and the other part is stored in the second cavity 1012.

[0060] Specifically, in one embodiment, the liquid storage chamber 101 is 10ml, the first cavity 1011 occupies 5ml, and the second cavity 1012 occupies 5ml, wherein the default volume of the liquid storage interval 1010 is 1ml, and the liquid aerosol generating matrix that can be effectively utilized in the first cavity 1011 is: 5ml*68%=3.4ml; the liquid aerosol generating matrix that can be effectively utilized in the second cavity 1012 is: 5ml-0.5ml (gap volume)=4ml; the total amount of liquid aerosol generating matrix that can be effectively utilized in the liquid storage chamber 101 is: 3.4ml+4ml=7.4ml; the liquid aerosol generating matrix that can be effectively utilized in the liquid storage chamber 101 only accounts for: 7.4ml / 10ml=74% of the volume of the liquid storage chamber 101.

[0061] In another embodiment, the liquid storage chamber 101 is 10ml, the first cavity space occupies 7ml, and the second cavity occupies 3ml, wherein the default volume of the liquid storage interval 1010 is 1ml, then the liquid aerosol generating matrix that can be effectively utilized in the first cavity 1011 is: 7ml*68%=4.76ml; the liquid aerosol generating matrix that can be effectively utilized in the second cavity 1012 is: 3ml-1ml=2ml; the total amount of liquid aerosol generating matrix that can be effectively utilized in the liquid storage chamber 101 is: 4.76ml+2ml=6.76ml≈6.8ml; the liquid aerosol generating matrix that can be effectively utilized in the liquid storage chamber 101 only occupies 6.8ml / 10ml=68% of the volume of the liquid storage chamber 101.

[0062] In another embodiment, the liquid storage chamber 101 is 10ml, the first cavity 1011 occupies 3ml, and the second cavity 1012 occupies 7ml, wherein the default volume of the liquid storage compartment 1010 is 1ml, then the liquid aerosol generating matrix that can be effectively utilized in the first cavity 1011 is: 3ml*68%=2.04ml; the liquid aerosol generating matrix that can be effectively utilized in the second cavity 1012 is: 7ml-1ml=6ml; the total amount of liquid aerosol generating matrix that can be effectively utilized in the liquid storage chamber 101 is: 2.04ml+6ml=8.04ml≈8.04ml; the liquid aerosol generating matrix that can be effectively utilized in the liquid storage chamber 101 only occupies 8.04ml / 10ml=80.4% of the volume of the liquid storage chamber 101.

[0063] In summary, when the volume of the default liquid storage interval 1010 is 1 ml, the proportion of the liquid aerosol generating substrate that can be effectively utilized in the liquid storage cavity 101 in the embodiment of the present application is always not less than the proportion of the liquid aerosol generating substrate that can be effectively utilized in the liquid storage cavity 101 in the prior art. In addition, the volume of the default liquid storage interval 1010 can continue to be reduced according to demand. It can be understood that the smaller the first cavity 1011 and the larger the second cavity 1012, the higher the proportion of the liquid aerosol generating substrate that can be effectively utilized in the liquid storage cavity 101.

[0064] In summary, the atomization device 100 provided in the embodiment of the present application can, on the one hand, maintain a stable concentration of the liquid aerosol generating matrix in the adsorption component 30, thereby ensuring that the taste of the atomization device 1000 is consistent before and after, and on the other hand, it can increase the capacity of the liquid aerosol generating matrix that can be effectively utilized in the liquid storage chamber 101.

[0065] Please refer to Figure 1 , Figure 2 and Figure 3 The liquid storage assembly 10 includes a cup body 11 and a first seal 12 and a second seal 13 connected to both ends of the cup body 11. The first seal 12, the second seal 13 and the cup body 11 are arranged to form a liquid storage cavity 101. The first seal 12 is connected to the first cavity 1011, and the second seal 13 is connected to the second cavity 1012.

[0066] The first sealing member 12 is provided with a first through hole 120, and the second sealing member 13 is provided with a second through hole 130 corresponding to the first through hole 120. One end of the atomizer assembly 20 is connected to the first through hole 120, and the end of the atomizer assembly 20 away from the first through hole 120 is connected to the second through hole 130. External air enters the atomization channel 201 of the atomizer assembly 20 from the second through hole 130, and drives the aerosol generated in the atomization channel 201 to flow out from the first through hole 120.

[0067] The atomizing assembly 20 is provided with an atomizing channel 201, through which the external air, i.e. the aerosol generated by atomization, flows for use by the user. The atomizing assembly 20 includes an atomizing core 21, which is embedded in the adsorbent 30 and communicates with the adsorbent 30 to adsorb and atomize the heated liquid aerosol-generating matrix to generate an aerosol. The atomizing core 21 at least forms a part of the atomizing channel 201, so that the generated aerosol enters the atomizing channel 201.

[0068] The atomizer core 21 includes a fixed tube 211, a heating mesh 212, and a liquid guide layer 213. The heating mesh 212 is received in the fixed tube 211 and arranged around the inner wall of the fixed tube 211, and the heating mesh 212 is arranged to form a heating chamber 2120. The liquid guide layer 213 is received in the fixed tube 211, and the liquid guide layer 213 is sandwiched between the inner wall of the fixed tube 211 and the heating mesh 212.

[0069] Please refer to Figure 1 , Figure 3 and Figure 4 One end of the fixed cylinder 211 can be communicated with the first through hole 120, and the end of the fixed cylinder 211 away from the first through hole 120 can be communicated with the second through hole 130. A communication port 2110 can be provided on the wall of the fixed cylinder 211, and the atomizing core 21 can be connected to the adsorbent 30 through the communication port 2110, so that the aerosol generating matrix can flow from the adsorbent 30 to the atomizing core 21 through the communication port 2110, so that the adsorbent 30 can supply liquid for the heating and atomizing function of the atomizing core 21.

[0070] The outer peripheral surface of the fixed cylinder 211 is also provided with a liquid outlet hole 2111, and the liquid outlet hole 2111 is connected to the liquid guide layer 213 and the liquid storage space 1010. The liquid outlet hole 2111 is arranged corresponding to the liquid storage space 1010, that is, the liquid outlet hole 2111 is located below the adsorbent 30. When the aerosol generating matrix flowing from the adsorbent 30 to the liquid guide layer 213 through the connecting port 2110 is oversaturated and cannot be completely absorbed and consumed by the liquid guide layer 213, the saturated and overflowed aerosol generating matrix can flow back from the liquid outlet hole 2111 into the liquid storage space 1010, which is beneficial to improve the utilization rate of the liquid aerosol generating matrix, prevent waste, and help prevent the liquid aerosol generating matrix that is not absorbed by the liquid guide layer 213 from being retained in the atomization channel 201 and leaking. The atomization core 21 can also adopt other structures, such as a ceramic atomization core.

[0071] Some existing aerosol atomization equipment can only maintain a liquid storage cotton filling rate of 70%-80% due to the internal pressure of the oil cup, oil leakage, and the oil absorption rate of the liquid storage cotton. After the aerosol atomization equipment is used, there will still be a certain amount of liquid aerosol generating matrix in the liquid storage cotton, and the residual rate is 15%-20%. The oil-conducting cotton on the atomization core cannot completely absorb the liquid aerosol generating matrix inside the liquid storage cotton into the atomization core for atomization. In this application, when the adsorbent 30 is saturated with liquid, when too much liquid aerosol generating matrix is ​​supplied, the excess aerosol generating matrix will flow back along the atomization channel 201 and the liquid outlet 2111, effectively preventing leakage caused by excessive liquid injection of the adsorbent 30.

[0072] Therefore, the adsorbent 30 in the present application can maintain a liquid filling rate equal to or close to 100%, effectively overcoming the above-mentioned problem. Due to the reduction in the volume of the adsorbent 30, the residual liquid rate of the adsorbent 30 will be reduced, which can reach below 7%, which is conducive to increasing the service life and reducing production costs. The selection of the adsorbent 30 can take into account the number of times it can be puffed, for example, 600 times, that is, after the adsorbent 30 is filled with liquid, it can be puffed 600 times by the user, which is far greater than the battery power supply limit, so that when the battery is charged and placed horizontally, the adsorbent 30 adsorbs the liquid aerosol to generate the matrix and reaches a saturated state, effectively improving the taste stability of the user before and after use.

[0073] The heating mesh 212 includes a mesh portion 2121 and a plurality of conductive pins 2122 connected to the mesh portion 2121. In some embodiments, the heating mesh 212 includes a mesh portion 2121 and two conductive pins 2122, and the two conductive pins 2122 are electrically connected to two ends of the mesh portion 2121, respectively.

[0074] In some other embodiments, the heating mesh 212 includes two mesh portions 2121 and three conductive pins 2122. Specifically, one of the three conductive pins 2122 is a first conductive pin, and the remaining two are second negative conductive pins. One end of each mesh portion 2121 is electrically connected to the first conductive pin, and one end of each mesh portion 2121 is electrically connected to a second conductive pin. The first conductive pin is one of a positive pin and a negative pin, and the second conductive pin is the other of the positive pin and the negative pin.

[0075] The liquid-conducting layer 213 is connected to the adsorbent 30 through the communication port 2110, and the aerosol-generating matrix in the adsorbent 30 is transferred to the heating mesh 212 through the liquid-conducting layer 213, and is supplied to the heating mesh 212 for heating and atomization, and generates aerosol in the heating chamber 2120. The material of the liquid-conducting layer 213 can be one of a cotton core and a linen, and is not specifically limited here.

[0076] Please continue to refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The atomizer base 22 includes a base tube 221 and a plug-in portion 222 connected to the base tube 221. One end of the base tube 221 away from the plug-in portion 222 is plugged into the second through hole 130, and one end of the plug-in portion 222 away from the base tube 221 is plugged into the fixed tube 211 of the atomizer core 21. A first cavity 2210 is provided in the base tube 221, and a second cavity 2220 is provided in the plug-in portion 222. The second cavity 2220 is communicated with the first cavity 2210, that is, the first cavity 2210 and the second cavity 2220 form part of the atomizer channel 201.

[0077] In this embodiment, the base tube 221 is cylindrical, and the first cavity 2210 is cylindrical. The plug-in portion 222 is truncated cone-shaped or frustum-shaped, and the transverse cross-sectional area of ​​the plug-in portion 222 gradually decreases from one end of the base tube 221 to the end away from the base tube 221. The plug-in portion 222 is at least partially plugged into the fixed tube 211, and the tip of the plug-in portion 222 is spaced from the liquid-conducting layer 213. The outer periphery of the plug-in portion 222 with a gradual cross-section has a guiding effect on the liquid aerosol generating matrix, so that the liquid aerosol generating matrix dripping from the liquid-conducting layer 213 can be guided by the outer peripheral surface of the plug-in portion 222 and then flow downward quickly, and then discharged into the liquid storage space 1010 through the liquid outlet 2111. The second cavity 2220 is located at the axial position of the plug-in portion 222 to prevent the aerosol generating matrix from dripping into the second cavity and causing leakage.

[0078] The plug-in portion 222 is also provided with a plurality of threading holes 2221 extending along the axial direction thereof, and the plurality of threading holes 2221 are respectively arranged in one-to-one correspondence with the plurality of conductive pins 2122 of the heating mesh 212. After one end of each conductive pin 2122 away from the mesh portion 2121 passes through the corresponding threading hole 2221, part of the second cavity 2220 and the first cavity 2210 in sequence, it is electrically connected to the control unit. Among them, the threading hole 2221 is mainly used to position and fix the conductive pin 2122, so as to facilitate the routing of the conductive pin 2122.

[0079] Specifically, the threading hole 2221 can be a conical hole. After the conductive pin 2122 is inserted into the threading hole 2221, UV glue (i.e., ultraviolet curing glue) can be applied from the conical hole. The UV glue is filled between the conductive pin 2122 and the threading hole 2221 to achieve sealing and fixation of the conductive pin 2122 and the threading hole 2221, thereby preventing liquid leakage at the threading hole 2221.

[0080] Please continue reading Figure 2 , Figure 3 and Figure 4 A plurality of positioning grooves 2222 are also provided on the outer circumference of the plug-in portion 222. One end of the fixed tube 211 connected to the base tube 221 extends to form a plurality of positioning piles 2112, and the plurality of positioning piles 2112 are arranged one by one in correspondence with the plurality of positioning grooves 2222. The plurality of positioning piles 2112 are respectively inserted into the corresponding positioning grooves 2222, which can realize the rapid alignment of the fixed tube 211 and the atomizing base 22 on the one hand, facilitate the insertion of the conductive pins 2122, and improve the reliability of the connection between the fixed tube 211 and the atomizing base 22 on the other hand.

[0081] Specifically, the fixed cylinder 211 may be cylindrical, and at least one notch is provided at the bottom of the fixed cylinder 211, and the number of notches may be 1, 2, 3 or more. The plurality of notches are spaced apart at the bottom of the fixed cylinder 211. When three notches are provided, the bottom of the fixed cylinder 211 is divided into three positioning piles 2112 by the three notches, and the three positioning piles 2112 are inserted into the three positioning grooves 2222 of the atomizing base 22 for fixing.

[0082] Since the bottom end of the fixed cylinder 211 is connected to the atomizing base 22, the notch and the atomizing base 22 form a liquid outlet 2111, so that the excess aerosol generating substrate not adsorbed by the atomizing core 21 can flow back from the liquid outlet 2111 to the second cavity 1012, which is beneficial to improve the utilization rate of the liquid aerosol generating substrate, realize recycling, and help prevent the liquid aerosol generating substrate not adsorbed by the liquid guide layer 213 from leaking through the atomizing channel 201. The diameter of the hollow inner cavity of the atomizing base 22 can be 2 mm, which can effectively keep the airflow unobstructed.

[0083] Please continue to refer to Figure 1 and Figure 4 , wherein the atomizing base 22 further comprises a shielding portion 223, which is sleeved at the connection between the base tube 221 and the plug-in portion 222, wherein the shielding portion 223 is located in the liquid storage compartment 1010. When the user inhales and uses the atomizing device 1000, due to the increase in internal pressure or excessive injection, the liquid aerosol generating matrix has a certain viscosity, so that the excess aerosol generating matrix that is not adsorbed by the liquid guiding layer 213 flows down along the conductive pins 2122 of the heating mesh 212 and the inner wall of the fixed tube 211, and falls on the top surface of the shielding portion 223 through the liquid outlet hole 2111, and then flows and diffuses around, and the shielding portion 223 realizes the receiving and guiding effect on the liquid aerosol generating matrix, so that the excess aerosol generating matrix flows back into the liquid aerosol generating matrix stored in the second cavity 1012.

[0084] Furthermore, when the user turns the atomization device 1000 on its side or places it sideways, the aerosol generating matrix in the second cavity 1012 first falls on the bottom surface of the shielding portion 223 under the action of gravity, gathers and then flows and diffuses around. The shielding portion 223 has a shielding and buffering effect on the liquid outlet 2111. On the one hand, it prevents the liquid aerosol generating matrix from entering the fixed cylinder 211 through the liquid outlet 2111 and causing leakage, so that the liquid aerosol generating matrix directly falls onto the adsorbent 30. On the other hand, it can separate the first chamber 2011 and the second chamber 2012, so that the aerosol generating matrix in the second chamber 2012 can only enter the first chamber 2011 from the edge area, thereby ensuring the stability of the aerosol generating matrix concentration near the atomization core 21.

[0085] In this embodiment, the shielding portion 223 includes a first surface 2231 and a second surface 2232 that are arranged opposite to each other, the first surface 2231 protrudes in a direction away from the second surface 2232, and the second surface 2232 protrudes in a direction away from the first surface 2231, that is, the first surface 2231 is inclined outwardly in the circumferential direction away from the fixed cylinder 211, and the second surface 2232 is inclined outwardly in the circumferential direction toward the fixed cylinder 211. The raised first surface 2231 has a guiding effect on the excess aerosol generating matrix flowing down from the liquid guide layer 213, and prompts the liquid aerosol generating matrix to quickly flow back to the liquid aerosol generating matrix stored in the second cavity 1012. When the user inverts the atomizing device 1000, the aerosol generating matrix in the second cavity 1012 falls on the second surface 2232 of the shielding portion 223, and the raised second surface 2232 can prompt the aerosol generating matrix to quickly flow and diffuse around, and quickly flow to the adsorbent 30. When the atomizer 100 is produced and assembled, the amount of liquid injected into the liquid storage chamber 101 is selected: after the adsorption component 30 is fully adsorbed, the atomizer 100 is placed normally with the adsorption component 30 on top and the atomizer base 22 on the bottom. The liquid level of the liquid aerosol generating matrix in the second cavity 1012 (i.e., the safe liquid level) needs to be kept below the second surface 2232 of the shielding portion 223 as much as possible, so that there is no liquid aerosol generating matrix between the second surface 2232 of the shielding portion 223 and the adsorption component 30, and it is in a hollow state, which can help prevent the liquid aerosol generating matrix from backflowing and leaking, and help keep the atomization channel 201 and the external air flow unobstructed, thereby making the internal air pressure of the atomizer 1000 balanced with the outside world under high and low pressure environments to avoid leakage.

[0086] Please continue reading Figure 2 , Figure 3 and Figure 4 In another embodiment, the atomizer assembly 20 further includes an air guide tube 23. One end of the air guide tube 23 is connected to one end of the fixed cylinder 211 away from the atomizer base 22, and one end of the air guide tube 23 away from the fixed cylinder 211 is connected to the first through hole 120. The atomizer base 22, the atomizer core 21 and the air guide tube 23 are sequentially connected to form an atomizer channel 201, and the atomizer channel 201 is used to allow external air to flow in, keep the airflow unobstructed, and allow the aerosol generated by atomization to be discharged smoothly.

[0087] Please continue reading Figure 2 , Figure 3 and Figure 4 In one embodiment, the atomizing assembly 20 may further include a shielding cover 24, which is used to prevent the liquid aerosol-generating matrix from flowing back into the fixed cylinder 211 through the liquid outlet 2111 when the atomizing device 1000 is inverted, causing leakage.

[0088] The shielding cover 24 is provided with a sleeve hole 240, and the shielding cover 24 is sleeved on the fixing tube 211 through the sleeve hole 240. A stopper 2113 is provided at one end of the fixing tube 211 close to the atomizing base 22, and the shielding cover 24 abuts against the stopper 2113.

[0089] Further, a stopper 2113 is protruded from the periphery of one end of the fixed cylinder 211 near the atomizing base 22, and the shielding cover 24 abuts against the stopper 2113. The stopper 2113 is arranged adjacent to the notch, and has a limiting effect on the installation of the shielding cover 24 on the fixed cylinder 211, which can facilitate the installation of the shielding cover 24 in the assembly process of the atomizing assembly 20, improve the convenience of assembly and ensure the qualified rate of the product after assembly. The stopper 2113 can be formed by folding the removed part of the notch outward when the notch is made to save materials. The number of the stoppers 2113 can be the same as the number of notches, for example, 3 notches correspond to 3 stoppers.

[0090] Specifically, the shielding cover 24 has a fixing portion 241 and a partition 242. The fixing portion 241 is provided with a sleeve hole 240, and is fitted on the outer periphery of the fixing tube 211 for sealing and fixing with the fixing tube 211. The partition 242 is located at one end of the fixing portion 241 close to the atomizing base 22, and the partition 242 is spaced from the portion of the fixing tube 211 where the notch is provided in the circumferential direction of the fixing tube 211. The partition 242 cooperates with the fixing portion 241 to separate the notch from the liquid storage space 1010 in the circumferential direction of the notch.

[0091] When the atomizing device 1000 is initially used, the aerosol generating matrix is ​​not consumed excessively. When the atomizing device 1000 is turned upside down, the aerosol generating matrix flows to the adsorbent 30 and is adsorbed by the adsorbent 30. The remaining aerosol generating matrix not adsorbed by the adsorbent 30 may submerge the bottom surface of the adsorbent 30. Since the partition 242 cooperates with the fixing portion 241 to separate and shield the gap, the aerosol generating matrix cannot flow back into the fixed cylinder 211 through the liquid outlet, thereby effectively preventing leakage.

[0092] The connection relationship between the fixing portion 241 and the partition portion 242 can be specifically that the partition portion 242 is connected to the portion of the bottom end of the fixing portion 241 that protrudes outward, or that the portion of the top end of the partition portion 242 that protrudes inward is connected to the bottom end of the fixing portion 241, or that the portion of the top end of the partition portion 242 that protrudes inward is connected to the portion of the bottom end of the fixing portion 241 that protrudes outward.

[0093] In this embodiment, the outer periphery of the adsorbent 30 is arranged to fit the first cavity 1011, which is conducive to the installation and fixation of the adsorbent 30 in the first cavity 1011, and the atomization device 1000 is placed horizontally, inverted or in other non-normal usage states, so that the liquid aerosol generating matrix in the second cavity 1012 can contact the adsorbent 30 as much as possible when flowing to the adsorbent 30, which is conducive to the adsorbent 30 to fully adsorb the aerosol generating matrix.

[0094] Please refer to Figure 1 and Figure 5 A guide groove 301 connecting the top and bottom surfaces of the adsorbent 30 is provided on the periphery of the adsorbent 30. The guide groove 301 is arranged along a preset direction, such as the height direction when the atomizing device 1000 is used for suction. The guide groove 301 is used for allowing the liquid aerosol generating matrix to flow through, so that the aerosol generating matrix can maintain contact with the wall surface of the guide groove 301 and the bottom and top surfaces of the adsorbent 30, which is beneficial for the adsorbent 30 to fully adsorb the aerosol generating matrix and improve the adsorption efficiency.

[0095] In this embodiment, the guide groove 301 may have a width of 2 mm. The guide groove 301 is distributed around the adsorbent 30 , which helps to achieve rapid liquid conduction and promotes the adsorbent 30 to adsorb liquid aerosol to generate a matrix.

[0096] The present application provides an atomization device and an atomization equipment, the atomization device comprising a liquid storage component, an atomization component and an adsorbent; the liquid storage component can be divided into a first cavity and a second cavity, the adsorbent is accommodated in the first cavity of the liquid storage cavity, and is used to adsorb and store part of the liquid aerosol generating matrix in the liquid storage cavity, and a liquid storage interval is formed between the bottom surface of the adsorbent and the liquid surface formed by the aerosol generating matrix in the second cavity; when the user does not inhale and use the atomization equipment, and the atomization equipment is placed horizontally or upside down, the liquid aerosol generating matrix in the second cavity flows to the adsorbent, and the aerosol generating matrix is ​​replenished for the adsorbent, so that the capacity of the aerosol generating matrix in the adsorbent remains stable during each inhalation, thereby achieving stable liquid supply to the atomization component, effectively ensuring the stability of the aerosol concentration generated by atomization when the atomization equipment is used normally, and achieving a stable taste before and after the use of the atomization equipment.

[0097] It should be understood that the application of the present application is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to this application.
