Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomization device. Background Technology

[0002] For open-type liquid-filling atomizers, users often experience coil clogging due to delayed liquid filling. Related technologies typically address this by adding or enlarging the viewing window to allow users to monitor the liquid level and facilitate timely filling when the level is low. Alternatively, increasing the capacity of the liquid reservoir can reduce the frequency of filling. However, these adjustments still present the potential for coil clogging due to delayed liquid filling. Utility Model Content

Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0019] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the objects being described and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0020] like Figures 1 to 13As shown, this application provides an atomizing device 1. The atomizing device 1 may include a housing 10, an atomizer 20, a liquid replenishment module 30, a control module 40, and a power supply module 50. The control module 40 and the power supply module 50 are housed within the housing 10, and the atomizer 20 and the liquid replenishment module 30 are at least partially housed within the housing 10. The atomizer 20, when powered on, atomizes an aerosol matrix to generate an aerosol for user use. The liquid replenishment module 30 is in fluid communication with the atomizer 20 and is used to replenish the atomizer 20 with liquid. The control module 40 is electrically connected to the atomizer 20, the liquid replenishment module 30, and the power supply module 50, respectively, and is used to control the normal operation of the atomizing device 1. The power supply module 50 provides electrical energy for the operation of the atomizing device 1.

[0021] The atomizing device 1 is now defined to include a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. Then in... Figure 1 In the embodiment shown, the atomizing device 1 is generally flat and cylindrical, with its height direction being the first direction X, its width direction being the second direction Y, and its thickness direction being the third direction Z.

[0022] Of course, the atomizing device 1 may also take various shapes such as cylindrical, polygonal columnar, elliptical columnar, disc-shaped, polygonal, ellipsoidal, spherical, hemispherical, irregular, etc. in other embodiments, and no specific limitation is made here.

[0023] like Figure 2 and Figure 6 As shown, in some embodiments, the atomizer 20 is disposed on the housing 10 along a first direction X, and includes a housing 21, an atomizing core 22, a mouthpiece 26, and at least three electrode needles. The housing 21 has a liquid storage chamber 211 and an atomizing chamber 212 in fluid communication with the liquid storage chamber 211. The liquid storage chamber 211 is used to store an aerosol matrix. The atomizing core 22 is disposed in the atomizing chamber 212 and is in liquid-conducting communication with the liquid storage chamber 211, so that the aerosol matrix in the liquid storage chamber 211 flows to the atomizing core 22 for atomization. The atomizing core 22 is also in fluid communication with the atomizing chamber 212, so that the atomized aerosol is located within the atomizing chamber 212. The atomizing core 22 is also electrically connected to the control module 40 for atomizing the aerosol matrix in the liquid storage chamber 211. The mouthpiece 26 is disposed on the housing 21 and has an air outlet channel 261, which is connected to the atomizing chamber 212. The suction nozzle 26 is at least partially exposed outside the housing 10 to facilitate suction by the user.

[0024] The housing 21 is also provided with an air inlet (not shown in the figure) that communicates with the atomizing chamber 212. After the liquid aerosol matrix is ​​atomized to generate aerosol, it is located in the atomizing chamber 212. During the user's inhalation, outside air enters the atomizing chamber 212 through the air inlet, mixes with the aerosol matrix in the atomizing chamber 212, and flows out together through the air outlet channel 261 for the user's use.

[0025] See also Figure 7 Each electrode needle extends from the bottom wall of the housing 21 into the liquid storage chamber 211, and the extension length of different electrode needles in the liquid storage chamber 211 is different, which is used to detect the liquid level in the liquid storage chamber 211.

[0026] exist Figure 7 In the illustrated embodiment, there are three electrode needles, which are now defined as the first electrode needle 23, the second electrode needle 24, and the third electrode needle 25. The third electrode needle 25, the second electrode needle 24, and the first electrode needle 23 all extend from the bottom wall of the housing 21 into the liquid storage cavity 211, and are all electrically connected to the control module 40.

[0027] By installing three electrode needles of unequal extension lengths within the liquid storage chamber 211, different height positions within the chamber can be detected. This allows users to flexibly perform liquid injection operations based on the liquid level detected by the electrode needles. The electrode needle design avoids the problem of core clogging caused by delayed injection and eliminates the need for frequent injection operations due to fear of core clogging. Users only need to perform the injection operation when the liquid level is at the required position based on the detection information provided by the electrode needles, thus improving the user experience.

[0028] It should be noted that the atomization method of the atomizing device 1 is not limited. For example, it can adopt one or more of the existing atomization methods such as resistance heating atomization, electromagnetic heating atomization, and infrared heating atomization. The atomizing core 22 can adopt the corresponding existing structure to realize the atomization method, and no specific limitation is made here.

[0029] It should be noted that the suction nozzle 26 can be detachably or non-detachably mounted on the housing 21 through methods such as integral molding, snap-fit ​​connection, threaded connection, bolt connection, or interference fit, and no specific limitation is made here.

[0030] like Figure 6 and Figure 7 As shown, the ends of the three electrode needles in the liquid storage chamber 211 are all exposed conductive terminals, and each conductive terminal is electrically connected to the control module 40. The on / off state of at least two conductive terminals is configured to respond to the liquid level height in the liquid storage chamber 211.

[0031] The exposed conductive terminal of the end of the first electrode needle 23 within the liquid storage cavity 211 is defined as the first conductive terminal 230. The exposed conductive terminal of the end of the second electrode needle 24 within the liquid storage cavity 211 is defined as the second conductive terminal 240. The exposed conductive terminal of the end of the third electrode needle 25 within the liquid storage cavity 211 is defined as the third conductive terminal 250.

[0032] In some embodiments, the first conductive terminal 230, the second conductive terminal 240, and the third conductive terminal 250 are arranged sequentially along the length of the liquid storage cavity 211, that is, sequentially arranged along the first direction X.

[0033] Specifically, the second conductive terminal 240 is positioned within the liquid storage cavity 211 between the first conductive terminal 230 and the third conductive terminal 250 along the first direction X. The extension length of the third electrode needle 25 within the liquid storage cavity 211 is greater than the extension length of the second electrode needle 24 within the liquid storage cavity 211. The extension length of the second electrode needle 24 within the liquid storage cavity 211 is greater than the extension length of the first electrode needle 23 within the liquid storage cavity 211.

[0034] It should be noted that the aerosol matrix has certain electrical conductivity, therefore the aerosol matrix in the liquid storage chamber 211 can serve as a circuit switch structure. The liquid level in the liquid storage chamber 211 determines the on / off state of the circuit.

[0035] For example, the third conductive terminal 250, the second conductive terminal 240, and the first conductive terminal 230 can be electrically connected to the control module 40 to form a circuit with two parallel branches. The first conductive terminal 230 can be considered as the common negative terminal in the two parallel branches. The third conductive terminal 250 and the second conductive terminal 240 can be considered as the positive terminals in the two parallel branches, respectively.

[0036] like Figure 8 As shown, when the liquid level in the storage chamber 211 is between the second conductive terminal 240 and the first conductive terminal 230 along the first direction X, both parallel branches are in an open circuit state. Figure 10 As shown, when the liquid level in the storage chamber 211 is between the third conductive terminal 250 and the second conductive terminal 240 along the first direction X, one branch is in a closed circuit state, and the other branch is in a closed circuit state. Figure 12 As shown, when the liquid level in the storage chamber 211 is at the third conductive terminal 250 along the first direction X, both branches are in a closed state.

[0037] The control module 40 can be configured to control the replenishment module 30 to replenish liquid into the storage chamber 211 when both branches are in an open circuit state, and to control the replenishment module 30 to stop replenishing liquid into the storage chamber 211 when both branches are in an open circuit state.

[0038] This configuration allows the atomizing device 1 to automatically start and stop replenishing liquid based on the liquid level. The atomizing device 1 is more intelligent. During use, the user does not need to constantly monitor the liquid level in the storage chamber 211, eliminating the need for manual replenishment and preventing clogging issues caused by delayed replenishment, thus improving the user experience.

[0039] In other embodiments, the control module 40 may also be configured to, when both branches are in an open circuit state, issue a prompt signal indicating that liquid replenishment is required, prompting the user to manually control the liquid replenishment module 30 to replenish liquid into the liquid storage chamber 211. When both branches are in an open circuit state, the control module 40 may issue a prompt signal indicating that liquid replenishment needs to be stopped, prompting the user to manually control the liquid replenishment module 30 to stop replenishing liquid into the liquid storage chamber 211.

[0040] It should be noted that the prompt signal can be a display signal, a sound signal, or other signal type, and no specific limitation is made here.

[0041] In some other embodiments, the third conductive terminal 250, the second conductive terminal 240, and the first conductive terminal 230 may also be three sensors for sensing the liquid level. The control module 40 may also be configured to control the replenishment module 30 to replenish the liquid storage chamber 211 based on the sensor signals, or to control the issuance of a prompt signal.

[0042] like Figure 6 As shown in Figure 7, in some embodiments, the three electrode needles are all longitudinally arranged, passing through the liquid storage chamber 21, and all extend from the bottom end of the liquid storage chamber 211 along the first direction X within the liquid storage chamber 211, and are arranged parallel to the axis of the liquid storage chamber 211.

[0043] It should be noted that when the atomizing device 1 is normally placed, it is usually in the position of Figure 1 The angle settings are shown below. Please refer to the following: Figure 7 and Figure 8 At this angle, the first direction X is parallel to the direction of gravity. That is, by setting the extension direction of the three electrode needles, the first conductive terminal 230, the second conductive terminal 240 and the third conductive terminal 250 can be arranged sequentially and spaced apart along the direction of gravity, so that the atomizing device 1 can realize the switching on and off of the two parallel branches based on different liquid levels, thereby realizing flexible liquid replenishment control.

[0044] like Figure 8 As shown, in some embodiments, the third conductive terminal 250 and the first conductive terminal 230 are located at opposite ends within the liquid storage cavity 211 along the first direction X.

[0045] Specifically, the first conductive terminal 230 is approximately located at the bottom end of the liquid storage chamber 211, and within the liquid storage chamber 211, it is approximately positioned near the bottom wall of the liquid storage chamber 211. The third conductive terminal 250 is approximately located at the top end of the liquid storage chamber 211, and within the liquid storage chamber 211, it is approximately positioned near the top wall of the liquid storage chamber 211. The second conductive terminal 240 is located between the two.

[0046] It should be noted that the bottom end of the liquid storage cavity 211 can be specifically understood as the starting end of the three electrode needles extending within the liquid storage cavity 211, or it can be understood as... Figure 1 The lowest horizontal position in the angle shown can be understood as the end of the liquid storage cavity 211 that is close to the control module 40 along the first direction X. The top of the liquid storage cavity 211 can be understood as the end opposite to the bottom of the liquid storage cavity 211 along the first direction X.

[0047] Now, along the first direction X, the bottom of the liquid storage cavity 211 is defined as 0% liquid level height, and the top of the liquid storage cavity 211 is defined as 100% liquid level height.

[0048] In some embodiments, the first conductive terminal 230 is approximately at 0% of the liquid level in the reservoir 211. The second conductive terminal 240 is approximately at 30% of the liquid level in the reservoir 211, meaning the length of the second electrode needle 24 along the first direction X within the reservoir 211 is 30% of the length of the reservoir 211 along the first direction X. The third conductive terminal 250 is approximately at 80% of the liquid level in the reservoir 211, meaning the length of the third electrode needle 25 along the first direction X within the reservoir 211 is 80% of the length of the reservoir 211 along the first direction X.

[0049] Of course, in some other embodiments, the position of the first conductive terminal 230 in the liquid storage chamber 211 can also be any other value between 0% and 10% of the liquid level.

[0050] In some other embodiments, the position of the second conductive terminal 240 within the liquid storage chamber 211 may also be any other value between 10% and 35% of the liquid level.

[0051] In some other embodiments, the third conductive terminal 250 may be positioned within the liquid storage chamber 211 at any other value between 75% and 90% of the liquid level.

[0052] like Figures 6 to 8As shown, in some embodiments, the first electrode needle 23 is generally tubular and disposed on the housing 21, including a first conductive tube. This first conductive tube is tubular, extends along a first direction X, and is partially located inside the liquid storage cavity 211 and partially outside the housing 21. Since the first conductive terminal 230 is approximately located at the bottom end of the liquid storage cavity 211, only the end of the first conductive tube is exposed inside the liquid storage cavity 211. The portion of the first conductive tube located inside the liquid storage cavity 211 can be considered as the first conductive terminal 230.

[0053] Furthermore, the first conductive tube can also be connected to the liquid replenishment module 30. The internal channel of the first conductive tube is connected to the liquid storage chamber 211 and the liquid replenishment chamber 321 of the liquid replenishment module 30 respectively, so that the liquid replenishment module 30 can replenish the liquid into the liquid storage chamber 211 through the internal channel of the first conductive tube.

[0054] By incorporating a cylindrical conductive tube into the first electrode needle 23, the first electrode needle can function as both a liquid level detection device and a conduit. This atomizer 20 achieves both liquid level detection and replenishment while reducing the number of components within the atomizer 20, minimizing its footprint within the housing 21, and lowering costs.

[0055] In some other embodiments, the first conductive tube may also be made of insulating material, and an electrical connection with the control module 40 may be achieved by embedding conductive leads in its wall and providing conductive terminals that are electrically connected to the conductive leads at the end of the first conductive tube located in the liquid storage cavity 211.

[0056] In some other embodiments, when the first conductive terminal 230 has a certain liquid level in the liquid storage chamber 211 (for example, the position of the first conductive terminal 230 in the liquid storage chamber 211 is at 5% liquid level), the first electrode needle 23 may further include an insulating layer. This insulating layer is at least disposed on the side wall of the first conductive tube located within the liquid storage chamber 211. In this embodiment, the end of the first conductive tube within the liquid storage chamber 211 is not covered by the insulating layer; this end can be considered as the first conductive terminal 230.

[0057] In other embodiments, the first electrode needle 23 may also be in the form of an elliptical tube, a polygonal tube, a semi-circular tube, an irregular tube, or other tubular shapes. When the first electrode needle 23 does not need to have a liquid guiding function, it may also be configured as various shapes such as columnar, plate-like, strip-like, rod-like, etc.

[0058] In some other embodiments, the first conductive tube may not extend outside the housing 21. Electrical connection between the first conductive tube and the control module 40 is achieved by providing an electrical connection structure, such as a lead wire connected to the first conductive tube, outside the housing 21.

[0059] like Figure 7 and Figure 8 As shown, in some embodiments, the second electrode needle 24 is generally cylindrical and includes a conductive post 241 and a first insulating layer 242. The conductive post 241 extends along a first direction X and is at least partially located within the liquid storage cavity 211. The first insulating layer 242 is disposed at least on the sidewall of the conductive post 241 located within the liquid storage cavity 211, serving to insulate the sidewall of the conductive post 241 from the aerosol matrix within the liquid storage cavity 211. The end of the conductive post 241 within the liquid storage cavity 211 is not covered by the first insulating layer 242; this end can be considered as the second conductive terminal 240.

[0060] It should be noted that the conductive post 241 may be partially located outside the housing 21 for electrical connection with the control module 40, or it may not extend outside the housing 21. The electrical connection between the conductive post 241 and the control module 40 can be achieved by setting an electrical connection structure such as a lead wire connected to the conductive post 241 outside the housing 21.

[0061] In some other embodiments, the conductive post 241 may also be made of insulating material, and by embedding conductive leads in its wall and providing conductive terminals that are electrically connected to the conductive leads at the end of the conductive post 241 located in the liquid storage cavity 211, it can be electrically connected to the control module 40.

[0062] In other embodiments, the second electrode needle 24 may also be in the form of an elliptical column, a polygonal column, a semi-circular column, an irregular column, or other columnar shapes. Of course, the second electrode needle 24 may also be configured as various plate-like, strip-like, rod-like, or other shapes.

[0063] like Figures 6 to 8 As shown, in some embodiments, the third electrode needle 25 is generally tubular and disposed on the housing 21, comprising a second conductive tube 251 and a second insulating layer 252. The second conductive tube 251 is tubular, extends along a first direction X, and is partially located inside the liquid storage cavity 211 and partially outside the housing 21. The second insulating layer 252 is disposed at least on the side wall of the second conductive tube 251 located inside the liquid storage cavity 211, serving to insulate the side wall of the second conductive tube 251 from the aerosol matrix inside the liquid storage cavity 211. The end of the second conductive tube 251 inside the liquid storage cavity 211 is not covered by the second insulating layer 252; this end can be considered as the third conductive terminal 250. The portion of the second conductive tube 251 located outside the housing 21 is used for electrical connection with the control module 40.

[0064] Furthermore, the second conductive tube 251 can also be connected to the liquid replenishment module 30. The internal channel of the second conductive tube 251 is connected to the liquid storage chamber 211 and the liquid replenishment chamber 321 of the liquid replenishment module 30 for gas conduction. When the liquid replenishment module 30 replenishes liquid into the liquid storage chamber 211 through the first conductive tube, the gas in the liquid storage chamber 211 can flow into the liquid replenishment chamber 321 through the second conductive tube to maintain a constant pressure in the liquid storage chamber 211 and the liquid replenishment chamber 321.

[0065] By incorporating a cylindrical second conductive tube 251 into the third electrode needle 25 and a second insulating layer 252 on its sidewall, the third electrode needle 25 achieves an integrated design, functioning both as a liquid level detection device and a conduit. This atomizer 20 maintains constant pressure in each chamber while simultaneously detecting and replenishing the liquid level, reducing the number of components within the atomizer 20, minimizing space occupation within the housing 21, and lowering costs.

[0066] It is important to understand that during the replenishment process of the replenishment module 30 into the storage chamber 211, if the liquid level of the aerosol matrix in the storage chamber 211 exceeds the position of the third conductive terminal 250, the aerosol matrix that has just been replenished into the storage chamber 211 will flow out through the tube channel of the third electrode needle 25. Ultimately, the liquid level in the storage chamber 211 is maintained at approximately the position of the third conductive terminal 250.

[0067] If the third conductive terminal 250 is positioned at a low height within the liquid storage chamber 211, and / or the first conductive terminal 230 is positioned at a high height within the liquid storage chamber 211, the amount of aerosol base that the replenishment module 30 can replenish into the liquid storage chamber 211 each time will be less, which is not conducive to reducing the replenishment frequency.

[0068] This application controls the first conductive terminal 230 and the third conductive terminal 250 to be located approximately at the two ends of the liquid storage chamber 211 along the first direction X. This allows the electrode needle to perform functions such as detecting liquid level, replenishing liquid, and balancing air pressure. At the same time, it can also increase the amount of liquid replenished by the replenishment chamber 32 to the atomizer 20 in a single replenishment of the aerosol matrix, thereby reducing the replenishment frequency.

[0069] In some other embodiments, the second conductive tube 251 may also be made of insulating material, and by embedding conductive leads in its wall and providing conductive terminals that are electrically connected to the conductive leads at the end of the second conductive tube 251 located in the liquid storage cavity 211, an electrical connection with the control module 40 can be achieved.

[0070] In other embodiments, the third electrode needle 25 may also be in the form of an elliptical tube, a polygonal tube, a semi-circular tube, an irregular tube, or other tubular shapes. When the third electrode needle 25 does not need to have a liquid guiding function, it may also be configured as various shapes such as columnar, plate-shaped, strip-shaped, rod-shaped, etc.

[0071] In some other embodiments, the second conductive tube 251 may not extend outside the housing 21. The electrical connection between the second conductive tube 251 and the control module 40 can be achieved by providing an electrical connection structure such as a lead wire connected to the second conductive tube 251 outside the housing 21.

[0072] It should be noted that the first conductive tube, conductive post 241, and second conductive tube 251 can be made of metals or alloys such as stainless steel, nickel alloy, and silver, or they can be made of porous ceramics (alumina or zirconia-based) doped with conductive phases (such as graphene, carbon nanotubes, or metal powder). No specific limitation is made here.

[0073] like Figures 2 to 5 As shown, in some embodiments, the replenishment module 30 may generally include a storage bottle 31, a replenishment chamber 32, and a pump body 33. The replenishment chamber 32 is provided with a replenishment cavity 321 for storing the aerosol matrix. The pump body 33 is in liquid-conducting communication with both the replenishment cavity 321 and the storage cavity 211, and is electrically connected to the control module 40, for pumping the aerosol matrix in the replenishment cavity 321 to the storage cavity 211 under the control of the control module 40. The storage bottle 31 is in liquid-conducting communication with the replenishment chamber 32 for replenishing the aerosol matrix to the replenishment cavity 321, further increasing the liquid storage capacity of the atomizing device 1.

[0074] Thus, when the liquid level of the aerosol matrix in the storage chamber 211 is lower than the height of the second conductive terminal 240, the control module 40 can control the pump body 33 to pump the aerosol matrix in the replenishment chamber 321 into the storage chamber 211 for continued use by the user. Simultaneously with the pumping of the aerosol matrix from the replenishment chamber 321 to the storage chamber 211, the gas in the storage chamber 211 can be synchronously transferred to the replenishment chamber 321 via the third electrode needle 25 to maintain constant pressure in both chambers. When the liquid level of the aerosol matrix in the storage chamber 211 reaches the height of the third conductive terminal 250, the control module 40 can control the pump body 33 to stop the replenishment of liquid from the replenishment chamber 32 to the atomizer 20.

[0075] The addition of the replenishment tank 32 increases the total amount of aerosol matrix that the atomizing device 1 can store, thereby reducing the frequency of users adding aerosol matrix to the atomizing device 1 and improving the user experience. At the same time, by increasing the total amount of aerosol matrix that the atomizing device 1 can store using the replenishment tank 32, there is no need to increase the volume of the liquid storage chamber 211, thus avoiding the problem of excessive pressure and oil leakage caused by an excessively large liquid storage chamber 211.

[0076] By setting up the pump body 33, when the aerosol matrix in the storage chamber 211 is exhausted, it is not necessary to manually replenish the aerosol matrix in the replenishment chamber 321 to the storage chamber 211.

[0077] With the cooperation of the pump body 33, control module 40 and three electrode needles, the liquid replenishment chamber 32 can automatically replenish the atomizer 20 without user operation, avoiding the problem of clogging caused by failure to replenish the liquid in time, and further improving the user experience.

[0078] Specifically, the pump body 33 is positioned approximately along the second direction Y between the replenishment chamber 32 and the control module 40. The pump body 33 and the control module 40 are positioned approximately at one end of the atomizer 20 along the first direction X. The storage bottle 31 is positioned at one end of the replenishment chamber 32 along the first direction X and on one side of the atomizer 20 along the second direction Y. The power supply module 50 is positioned along the first direction X at the end of the pump body 33 and the control module 40 opposite to the atomizer 20, and also along the first direction X at the end of the replenishment chamber 32 opposite to the storage bottle 31.

[0079] This spatial arrangement facilitates the construction of the liquid supply path from the replenishment chamber 321 to the storage chamber 211 and the exhaust path from the storage chamber 211 to the replenishment chamber 321, thereby improving the utilization rate of the space inside the outer shell 10.

[0080] By setting the liquid storage bottle 31 to be located at one end of the liquid replenishment chamber 32 along the first direction X, the aerosol matrix in the liquid storage bottle 31 can be automatically replenished into the liquid replenishment chamber 321 under the action of gravity.

[0081] In some other embodiments, the replenishment module 30 may include only the replenishment tank 32 and the pump body 33, without the storage bottle 31.

[0082] like Figure 3 and Figure 4 As shown, in some embodiments, the liquid replenishment module 30 further includes an air guide tube 35 and two liquid guide tubes 34. The portion of the tubular first electrode needle 23 extending outside the housing 21 can communicate with the pump body 33 via the liquid guide tubes 34. The pump body 33 can also communicate with the liquid replenishment chamber 32 via the liquid guide tubes 34. The portion of the tubular third electrode needle 25 extending outside the housing 21 can communicate with the liquid replenishment chamber 321 via the air guide tube 35.

[0083] Specifically, the portion of the first electrode needle 23 exposed outside the housing 21 is fitted onto the liquid guide tube 34, such that the first electrode needle 23 is arranged around the outer wall of the corresponding end of the liquid guide tube 34, thereby achieving the connection between the two. The portion of the third electrode needle 25 exposed outside the housing 21 is fitted onto the gas guide tube 35, such that the third electrode needle 25 is arranged around the outer wall of the corresponding end of the gas guide tube 35, thereby achieving the connection between the two.

[0084] In some other embodiments, the liquid guide tube 34 corresponds to the end of the first electrode needle 23 and may also be sleeved on the portion of the first electrode needle 23 exposed outside the housing 21. Alternatively, the gas guide tube 35 corresponds to the end of the third electrode needle 25 and may also be sleeved on the portion of the third electrode needle 25 exposed outside the housing 21.

[0085] In some embodiments, the horizontal position of the end of the air guide tube 35 connected to the liquid replenishment tank 32 may be higher than the horizontal position of the end of the liquid guide tube 34 connected to the liquid replenishment tank 32. That is, the horizontal position of the air inlet of the liquid replenishment chamber 321 is higher than the horizontal position of its liquid outlet.

[0086] For example in Figure 3 and Figure 4 In the illustrated embodiment, the end of the air guide tube 35 connected to the liquid replenishment tank 32 is located along the first direction X between the ends of the atomizer 20 and the liquid guide tube 34 connected to the liquid replenishment tank 32. In other words, the ends of the air guide tube 35 and the liquid replenishment tank 32 connected to each other, and the ends of the liquid guide tube 34 and the liquid replenishment tank 32 connected to each other, are approximately located at opposite ends of the liquid replenishment tank 32 along the first direction X.

[0087] When the atomizing device 1 is in normal placement, it is usually in the position of Figure 1 The angle settings are shown below. Please refer to the following: Figure 3 and Figure 4 At this angle, the end of the air guide tube 35 connected to the replenishment chamber 32 is approximately located near the top chamber wall of the replenishment chamber 321, and the end of the liquid guide tube 34 connected to the replenishment chamber 32 is approximately located near the bottom chamber wall of the replenishment chamber 321.

[0088] It is important to understand that during the process of pumping the aerosol matrix in the replenishment chamber 32 to the storage chamber 211 via the pump body 33, if the end of the guide tube 34 connected to the replenishment chamber 32 is located at a medium height position in the replenishment chamber 32, the aerosol matrix below this position will not be able to enter the guide tube 34 and thus cannot be pumped to the atomizer 20, resulting in a waste of aerosol matrix.

[0089] If the height of the end where the air duct 35 connects to the liquid replenishment chamber 32 is close to, or even equal to or lower than, the height of the end where the liquid duct 34 connects to the liquid replenishment chamber 32, then the aerosol matrix in the liquid replenishment chamber 321 will partially enter the air duct 35 due to gravity, which is not conducive to the conduction of the airflow path Q, and thus not conducive to maintaining a constant air pressure in the liquid storage chamber 211 and the liquid replenishment chamber 321 during the liquid replenishment process.

[0090] This embodiment controls the relationship between the height of the end connecting the air duct 35 and the liquid replenishment chamber 32 and the height of the end connecting the liquid duct 34 and the liquid replenishment chamber 32. This allows for maintaining normal operation of both the infusion path and the airflow path while increasing the capacity of the liquid replenishment chamber 321 to absorb aerosol matrix, thus preventing waste caused by aerosol matrix remaining in dead corners.

[0091] In other embodiments, the replenishment chamber 32 can also maintain a constant pressure within the replenishment cavity 321 by providing vent holes on its top wall. In this embodiment, the third electrode needle 25 can also be configured as a non-tubular structure.

[0092] like Figure 5 As shown, in some embodiments, the control module 40 may include a main control board 41 and a plurality of electrode posts 42. The main control board 41 is equipped with control circuitry for controlling the operation of the atomizing device 1. Among the plurality of electrode posts 42, at least three electrode posts 42 are electrically connected to three electrode needles, so that the control circuitry can control the replenishment module 30 to perform replenishment operations based on the liquid level detected by the three electrode needles.

[0093] like Figure 9 , Figure 11 and Figure 13 As shown, the electrode post 42 is now defined to include a first electrode post 421, a second electrode post 422, and a third electrode post 423.

[0094] Specifically, the first end of the first electrode post 421 is electrically connected to the second end of the main control board 41, and the second end is electrically connected to the first end of the third electrode needle 25. The first end of the second electrode post 422 is electrically connected to the second end of the main control board, and the second end is electrically connected to the first end of the second electrode needle 24. The second end of the third electrode post 423 is electrically connected to the first end of the main control board 41, and the first end is electrically connected to the second end of the third electrode needle 25.

[0095] like Figure 8 and Figure 9As shown, when the liquid level in the storage chamber 211 is between the second conductive terminal 240 and the first conductive terminal 230 along the first direction X, the second end of the first electrode needle 23 (i.e., the first conductive terminal 230) is disconnected from the second end of the second electrode needle 24 (i.e., the second conductive terminal 240), and is also disconnected from the second end of the third electrode needle 25 (i.e., the third conductive terminal 250). At this time, the control circuit on the main control board 41 is configured to control the pump body 33 to pump the aerosol matrix from the replenishment chamber 321 to the storage chamber 211.

[0096] like Figure 10 and Figure 11 As shown, when the liquid level in the storage chamber 211 is between the third conductive terminal 250 and the second conductive terminal 240 along the first direction X, the second end of the first electrode needle 23 (i.e., the first conductive terminal 230) is connected to the second end of the second electrode needle 24 (i.e., the second conductive terminal 240), but is disconnected from the second end of the third electrode needle 25 (i.e., the third conductive terminal 250).

[0097] like Figure 12 and Figure 13 As shown, when the liquid level in the storage chamber 211 is at the third conductive terminal 250 along the first direction X, the second end of the first electrode needle 23 (i.e., the first conductive terminal 230) is connected to the second end of the second electrode needle 24 (i.e., the second conductive terminal 240), and also connected to the second end of the third electrode needle 25 (i.e., the third conductive terminal 250). At this time, the control circuit on the main control board 41 is configured to control the pump body 33 to stop pumping liquid.

[0098] Specifically, the main control board 41 extends along the third direction Z and the first direction X. A plurality of electrode posts 42 are spaced apart on the main control board 41 along the third direction X, and each electrode post 42 extends along the second direction Y.

[0099] When the three electrode needles extend out of the housing 21 along the first direction X, the electrode post 42 can abut against the exposed part of the electrode needle along the second direction Y, thereby realizing the electrical connection between the electrode post 42 and the electrode needle.

[0100] This setup facilitates electrical connections without requiring conductive wires or other electrical connection structures, reducing problems caused by broken conductive wires during assembly and lowering production costs.

[0101] Of course, at least some of the three electrode needles may not extend outside the housing 21, but are electrically connected to the electrode post 42 through other electrical connection structures such as conductive wires.

[0102] For example in Figure 6 and Figure 7In the illustrated embodiment, the first electrode needle 23 and the third electrode needle 25 are spaced apart along the third direction Z on the housing 21 and are located at the same position on the housing 21 along the second direction Y. Therefore, the first electrode needle 23 and the third electrode needle 25 extend outside the housing 21 and abut against the two electrode posts 42 spaced apart along the third direction Z along the second direction Y, so as to achieve electrical connection with the control circuit.

[0103] The second electrode needle 24 is located on one side of the first electrode needle 23 and the second electrode needle 24 along the second direction Y. Therefore, the second electrode needle 24 does not extend outside the housing 21, but is electrically connected to the electrode post 42 through conductive wires or other electrical connection structures.

[0104] In some other embodiments, the second electrode needle 24 may also be disposed on the housing 21 at a distance from the first electrode needle 23 and the second electrode needle 24 along a third direction Z, and at the same position on the housing 21 along the second direction Y. In this case, the second electrode needle 24 may also optionally extend partially outside the housing 24 and abut against one of the electrode posts 42 along the second direction Y.

[0105] In some other embodiments, the first electrode needle 23 and / or the third electrode needle 25 may not extend outside the housing 21, but may be electrically connected to the electrode post 42 through other electrical connection structures such as conductive wires.

[0106] It should be noted that this atomizing device can be applied to the field of electronic cigarettes, as well as to medical, beauty, and other fields. The aerosol matrix can be in liquid form, such as medicinal liquids or oils, and can also include materials with medical, beauty, health, or flavor-enhancing functions. No specific limitations are made here.

[0107] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
