References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0026] In view of the problem that the liquid supply balance of existing atomization devices is difficult to control, the present application provides a liquid storage space between the sealing member and the liquid storage member, and provides a floating member at the liquid outlet of the liquid inlet channel of the sealing member. When atomized liquid accumulates in the liquid storage space, the liquid outlet can be blocked by the floating member, thereby avoiding the defect of the existing technology that the liquid supply balance is difficult to control, reducing the liquid locking capacity requirements of the liquid storage member, liquid guide member, etc. in the existing technology, and having the advantages of sustainable and stable liquid supply, high assembly fault tolerance, and avoidance of liquid leakage.

[0027] In one embodiment, Figure 1 、 Figure 2 As shown, the present application provides an atomization device 1, comprising an atomizer 10, and an atomized liquid bottle 20 connected to the atomizer 10 for supplying liquid. The atomized liquid bottle 20 is connected to a liquid inlet channel 141 to provide atomized liquid.

[0028] In one embodiment, Figures 1-6 As shown, an atomizer 10 is provided, comprising: a hollow liquid storage tank 11, an atomizing core assembly 12, a liquid storage member 13, a sealing member 14, and a floating member 15, etc.

[0029] The liquid storage tank 11 is a hollow structure, with one end being a liquid inlet 111 and the other end being provided with an atomization outlet 112. It is understood that the shape of the liquid storage tank 11 can be designed according to actual needs; the liquid inlet 111 and the atomization outlet 112 can be arranged at different positions of the liquid storage tank 11 as needed.

[0030] The liquid storage member 13 is used to absorb the atomized liquid and is disposed in the liquid storage tank 11. Its shape matches the shape of the inner cavity of the liquid storage tank 11, thereby allowing it to be positioned and disposed in the liquid storage tank 11. As shown in the figure, in some embodiments, the liquid storage member 13 is provided with a mounting hole 131. The atomizer core assembly 12 can be partially inserted into the mounting hole 131 and connected to the liquid storage member 13, thereby heating and atomizing the atomized liquid in the liquid storage member 13 through the atomizer core assembly 12 to generate an aerosol. It is understood that the connection method between the liquid storage member 13 and the atomizer core assembly 12 can adopt various existing connection and installation methods.

[0031] In one embodiment, the atomizer 10 may further include a nozzle 19. The nozzle 19 is disposed at the atomization outlet 112 of the liquid storage tank 11. The user can inhale the aerosol generated in the atomization channel 1211 through the nozzle 19. The nozzle 19 and the sealing member 14 are disposed at opposite ends of the liquid storage tank 11, and the direction of replenishment of the atomized liquid is consistent with the outflow direction of the aerosol.

[0032] The sealing member 14 is sealed at the liquid inlet end 111 of the liquid storage tank 11, thereby sealing the liquid storage member 13 in the liquid storage tank 11. Figure 3 、 4 As shown, a liquid storage space 16 is formed between the opposing end surfaces of the sealing member 14 and the liquid storage member 13. A liquid inlet channel 141 is also provided through the sealing member 14, communicating with the liquid storage space 16. The floating member 15 is at least partially disposed at a liquid outlet 142 of the liquid storage space 16 facing the liquid inlet channel 141, and can function as a switch to open or close the liquid outlet 142.

[0033] When the atomized liquid bottle 20 is assembled with the atomizer 10 , the atomized liquid bottle 20 is connected to the liquid inlet channel 141 of the sealing member 14 , and the atomized liquid can be replenished into the liquid storage tank 11 through the liquid inlet channel 141 .

[0034] In one embodiment, the liquid inlet channel 141 is located at the bottom of the liquid storage tank 11. That is, when the aerosol outlet of the atomizer device is normally placed upward, the nozzle 19 is facing upward, the atomizer liquid bottle 20 and the liquid inlet end 111 are located at the bottom of the liquid storage tank 11, and the bottle mouth of the atomizer liquid bottle 20 is facing upward. When the liquid storage tank 11 needs to be replenished, the user needs to invert the atomizer device so that the bottle mouth of the atomizer liquid bottle 20 is facing downward.

[0035] When the atomizing device is inverted, the atomized liquid bottle 20 is located above the liquid inlet channel 141, and the atomized liquid flows out from the outlet of the atomized liquid bottle 20 and flows from top to bottom. At the beginning of the filling phase, when the atomized liquid is injected through the liquid inlet channel 141, the floating member 15 moves away from the liquid outlet 142 under the push of the atomized liquid, thereby opening the liquid inlet channel 141. Figure 3 As shown, the atomized liquid can enter the liquid storage space 16 through the liquid inlet channel 141 and be adsorbed by the liquid storage member 13. When the liquid storage member 13 is saturated with adsorption, the atomized liquid will accumulate in the liquid storage space 16. When the atomized liquid accumulated in the liquid storage space 16 reaches a certain amount, the floating member 15 can be pushed to move toward the liquid outlet 142 of the liquid inlet channel 141 until the liquid outlet 142 is blocked. Figure 5 As shown, the atomized liquid cannot be further added, thereby ensuring that the liquid storage member 13 does not absorb too much atomized liquid and avoid the defect of leakage. In addition, there are no special requirements for the density and material of the liquid storage member 13, and its manufacturing process is simpler and has a higher fault tolerance rate.

[0036] In other embodiments, the suction nozzle 19 and the sealing member 14 may not be arranged at opposite ends of the liquid storage bin 11. For example, they may be arranged on the same side of the liquid storage bin 11, that is, the replenishment direction of the atomized liquid is opposite to the outflow direction of the aerosol. When the aerosol outlet of the atomizing device is placed normally with the aerosol outlet facing upward, the liquid inlet channel 141 may also be located at the top of the liquid storage bin 11, and the bottle mouth of the atomizing liquid bottle 20 faces downward. The atomized liquid can be automatically injected into the liquid storage bin 11 under the action of gravity. The floating member 15 can automatically open the liquid outlet 142 when the atomized liquid accumulated in the liquid storage space 16 is small, and can also automatically block the liquid outlet 142 when the atomized liquid accumulated in the liquid storage space 16 reaches a certain amount. The user no longer needs to manually invert the atomizing device frequently to achieve liquid replenishment.

[0037] In one embodiment, the average density of the floating member 15 is less than the density of the atomized liquid. When the atomized liquid accumulates in the liquid storage space 16, the floating member 15 can move toward the liquid outlet 142 under the buoyancy of the atomized liquid in the liquid storage space 16. When the amount of atomized liquid reaches a certain level, the floating member 15 is pushed to block the liquid outlet 142, thereby automatically stopping the liquid addition.

[0038] It is understandable that in some embodiments, the floating member 15 can be made of a material having a density lower than that of the atomized liquid, for example, PP or other plastics having a density lower than that of the atomized liquid.

[0039] In other embodiments, the float 15 can be hollow, with a cavity formed within it. Alternatively, the float 15 can be shaped like a boat, thereby increasing its buoyancy and making its average density less than that of the atomized liquid. In this case, the density of the material used for the float 15 can be greater than, equal to, or less than the density of the atomized liquid. By increasing the buoyancy of the float 15, the material selection restrictions for the float 15 can be reduced, resulting in greater versatility.

[0040] In one embodiment, if Figure 4 As shown, the height H of the liquid storage space 16 is less than the thickness h of the floating member 15, and the floating member 15 is at least partially located within the liquid inlet channel 141. During liquid injection, the floating member 15 moves away from the liquid outlet 142 and toward the liquid storage member 13. Due to the height restriction of the liquid storage space 16, the floating member 15 can remain within the space where the liquid outlet 142 is located, thus avoiding the problem of the floating member 15 shifting and being unable to re-block the liquid outlet 142.

[0041] It is understandable that in some embodiments, the movement direction of the floating member 15 can also be limited by adding a limiting guide structure, for example, adding a fence around the liquid outlet 142, and the floating member 15 is set within the space range of the fence.

[0042] In one embodiment, if Figure 6 As shown, the end face of the floating member 15 close to the liquid storage member 13 is provided with a liquid inlet groove 151 running through its periphery. When the end face of the floating member 15 contacts the end face of the liquid storage member 13, the provision of the liquid inlet groove 151 allows the atomized liquid to enter between the two end faces, thereby providing buoyancy and pushing the floating member 15 to move toward the liquid inlet channel 141. As shown in the figure, the liquid inlet grooves 151 are radially distributed on the end face of the floating member 15, thereby forming a plurality of channels, so that the atomized liquid can quickly enter between the floating member 15 and the liquid storage member 13, thereby providing sufficient buoyancy to push the floating member 15 to quickly block the liquid outlet 142. It can be understood that the shape and structure of the liquid inlet groove 151 can be adjusted according to needs, such as a cross shape, a plurality of slots arranged in parallel or staggered, etc.

[0043] In one embodiment, a section of the inlet channel 141 near the outlet 142 is formed as a tapered outlet section 143. Accordingly, the outer periphery of the float 15 includes a tapered surface that matches the tapered shape of the outlet section 143. The inner wall of the outlet section 143 is a trumpet-shaped tapered surface, larger on the outside and smaller on the inside. Accordingly, the outer periphery of the float 15 forms a tapered surface that matches the outlet section 143. This tapered structure allows the float 15 to be more accurately aligned with the inlet channel 141, creating a stable seal. It will be appreciated that in other embodiments, the shapes of the inlet channel 141 and the float 15 can be adjusted according to actual needs.

[0044] In one embodiment, a section of the liquid inlet of the liquid inlet channel 141 may also be configured as a tapered liquid inlet section 144 , thereby allowing the atomized liquid to enter the liquid inlet channel 141 more easily.

[0045] In one embodiment, the end surface of the sealing member 14 is provided with a plurality of protrusions 145 that are distributed and extend to the end surface of the liquid storage member 13; the space surrounding the protrusions 145 forms a liquid storage space 16. Due to the provision of these protrusions 145, when the sealing member 14 is assembled to the liquid inlet end 111 of the liquid storage tank 11, the protrusions 145 can contact the end surface of the liquid storage member 13, thereby forming a suspended space around the protrusions 145 to form the liquid storage space 16. This ensures that the sealing member 14 is pressed against the liquid storage member 13, and also avoids the situation where the sealing member 14 and the liquid storage member 13 are directly attached and the liquid storage space 16 cannot be formed due to process or structural deviations.

[0046] It is understandable that the positioning between the sealing member 14 and the liquid storage member 13 can also be achieved through other structural methods, such as adding bone positions in the inner wall of the liquid storage tank 11 to position the sealing member 14 and the liquid storage member 13, thereby ensuring the formation of the suspended space.

[0047] In one embodiment, the atomizer core assembly 12 includes a heating element 121 having an atomization channel 1211, a liquid guide 122 disposed on the periphery of the heating element 121 and connected to the liquid storage element 13, a pin 123 connected to the heating element 121 for accessing a power source, and an atomizer tube 124 disposed on the periphery of the liquid guide 122. It is understood that the heating element 121, the liquid guide 122, the pin 123, and the atomizer tube 124 can utilize various corresponding structures in the prior art.

[0048] Among them, the seal 14 is also provided with an air inlet channel 146 connected to the atomization channel 1211; the liquid storage tank 11 is provided with an atomization outlet 112 connected to the atomization channel 1211. Furthermore, the seal 14 is provided with a positioning groove 147 on the periphery of the air inlet channel 146, and the end of the atomization tube 124 is inserted into the positioning groove 147, thereby isolating the atomization channel 1211 in the heating element 121 from the liquid storage space 16, and preventing the atomized liquid in the liquid storage space 16 from entering the atomization channel 1211. The pin 123 can directly pass through the seal 14 and be connected to the power supply, which can also avoid contamination of the atomized liquid. It is understandable that the pin 123 can also pass through the seal 14 through the air inlet channel 146.

[0049] During operation, power is connected via pin 123, heating element 121. The liquid guide 122 then transfers the atomized liquid from the liquid reservoir 13 to the heating element 121, which heats the atomized liquid, thereby generating an aerosol in the atomization channel 1211. When the user inhales, outside air is introduced through the air inlet channel 146, which then carries the aerosol in the atomization channel 1211 out for the user to inhale.

[0050] In one embodiment, the atomizer 10 further includes a base 17 mounted on the liquid inlet end 111 of the liquid storage tank 11; the base 17 is provided with a liquid inlet cavity 171 connected to the liquid inlet channel 141. The atomized liquid can first enter the liquid inlet cavity 171 and then be transferred to the liquid storage member 13 through the liquid inlet channel 141.

[0051] In one embodiment, the base 17 is further provided with a piercing member 172 at the liquid inlet chamber 171, and the piercing member 172 can be used to pierce the connected atomized liquid bottle 20, so that the atomized liquid in the atomized liquid bottle 20 can flow into the liquid inlet chamber 171. It can be understood that in some embodiments, the piercing member 172 can also be omitted, and after the atomized liquid bottle 20 is opened, the atomized liquid can flow directly into the liquid inlet chamber 171.

[0052] In one embodiment, the atomizer 10 further includes a power supply assembly 18 mounted on the base 17 and located on one side of the liquid storage tank 11. It is understood that the power supply assembly 18 may include a battery, a control circuit board, etc., and the control circuit board outputs different currents and voltages to control the heating power of the atomizer core assembly 12, thereby controlling the aerosol generation rate to meet the needs of different users.

[0053] like Figure 2 As shown, in some embodiments, the base 17 may include a first base 173 and a second base 174 that are engaged with each other via a snap-fit ​​structure. A circuit board accommodating space 175 is formed between the first base 173 and the second base 174 for placing a control circuit board therein. The battery is mounted on the first base 173 and located on one side of the atomizer core assembly 12, thereby facilitating the connection of the pins 123 to the control circuit board.

[0054] The liquid inlet cavity 171 may be formed between the first base 173 and the second base 174 . Furthermore, a base seal 176 may be provided at the position of the liquid inlet cavity 171 to prevent leakage of the atomized liquid when the atomized liquid bottle 20 is inserted.

[0055] In some embodiments, an airtight member 191 may be provided between the nozzle 19 and the liquid reservoir 11 to prevent aerosol leakage. The airtight member 191 defines a ventilation channel connecting the nozzle 19 and the atomization outlet 112. It is understood that the nozzle 19 and the airtight member 191 may be connected via a snap-fit ​​mechanism; however, other methods of secure connection are also possible.

[0056] In some embodiments, the atomizing liquid bottle 20 can be pluggably connected to the atomizer 10. Of course, the atomizing liquid bottle 20 can also be fixedly arranged on the atomizer 10.

[0057] In some embodiments, the atomizing device 1 may include a housing 30 that encloses the atomizer 10 and the atomizing liquid bottle 20, excluding the nozzle 19, thereby making the entire device more beautiful and practical. It is understood that the housing 30 may include two parts, one part enclosing the atomizer 10 and the other part enclosing the atomizing liquid bottle 20, thereby facilitating replacement of the atomizing liquid bottle 20.

[0058] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
