When the atomizer liquid is consumed, the entire atomizer device must be discarded and cannot be reused, resulting in waste.

[0003] Therefore, some refillable atomizers are launched on the market, but the refilling speed of the liquid inlet is difficult to control. When the liquid storage component in the liquid storage tank is saturated with the atomized liquid, the refilling bottle continues to add the atomized liquid, resulting in excessive accumulation of atomized liquid in the liquid storage tank, thereby causing leakage. Summary of the invention

[0004] The present application provides an atomizer and an atomizing device, which are used to solve the problem that the liquid replenishment of the atomizing device in the prior art is difficult to control.

[0005] In one embodiment, an atomizer is provided, comprising: a hollow liquid storage tank, an atomizing core assembly, a liquid storage member, a sealing member and a floating member; the liquid storage member is arranged in the liquid storage tank, and the atomizing core assembly is connected to the liquid storage member; the sealing member is sealingly arranged at the liquid inlet end of the liquid storage tank; a liquid storage space is formed between the sealing member and the end surface opposite to the liquid storage member; the sealing member is provided with a through liquid inlet channel connected to the liquid storage space; the floating member is at least partially arranged at the liquid outlet of the liquid storage space facing the liquid inlet channel, and when atomized liquid is accumulated in the liquid storage space, the floating member blocks the liquid outlet.

[0006] In one embodiment, the average density of the floating member is less than the density of the atomized liquid; when the atomized liquid is accumulated in the liquid storage space, the floating member can block the liquid outlet under the push of the buoyancy of the atomized liquid in the liquid storage space.

[0007] In one embodiment, the height of the liquid storage space is smaller than the thickness of the floating member, and the floating member is at least partially located in the liquid inlet channel.

[0008] In one embodiment, a liquid inlet groove running through the periphery of the floating member is provided on one end surface of the floating member close to the liquid storage member.

[0010] In one embodiment, the end surface of the sealing member is provided with a plurality of protrusions which are distributed and extend to the end surface of the liquid storage member; and the liquid storage space is formed in the peripheral space of the protrusions.

[0011] In one embodiment, the atomization core assembly includes a heating element provided with an atomization channel, a liquid guiding element arranged on the periphery of the heating element and connected to the liquid storage element, a pin connected to the heating element and connected to a power supply, and an atomization tube arranged on the periphery of the liquid guiding element; the sealing element is also provided with an air inlet channel connected to the atomization channel; the liquid storage tank is provided with an atomization outlet connected to the atomization channel; the sealing element is provided with a positioning groove on the periphery of the air inlet channel, and the end of the atomization tube is inserted into the positioning groove; the pin passes through the sealing element.

[0015] According to the atomizer and atomization device of the above-mentioned embodiments, a liquid storage space is set between the sealing member and the liquid storage member, and a floating member is set at the liquid outlet position of the liquid inlet channel of the sealing member. When the atomized liquid starts to be replenished, the floating member opens the liquid outlet, so that the atomized liquid can be quickly replenished to the liquid storage member, and when the liquid storage member is saturated with adsorption, the atomized liquid begins to accumulate in the liquid storage space. Under the action of the accumulated atomized liquid, the floating member blocks the liquid outlet to prevent the atomized liquid from further entering the liquid storage tank, thereby avoiding the defect of still adding atomized liquid after the liquid storage member is saturated with adsorption. The atomized liquid filling has the advantages of controllable liquid leakage and avoidance of dry burning. BRIEF DESCRIPTION OF THE DRAWINGS

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0026] Aiming at the problem that the liquid supply balance of the existing atomization device is difficult to control. In this application, by setting a liquid storage space between the sealing part and the liquid storage part, and setting a floating part at the liquid outlet position of the liquid inlet channel of the sealing part, when the atomized liquid accumulates in the liquid storage space, the liquid outlet can be blocked by the floating part, thereby avoiding the defect of the existing technology that the liquid supply balance is difficult to control, reducing the requirements for the liquid locking ability of the liquid storage part, the liquid guide part, etc. in the existing technology, and having the advantages of sustainable and stable liquid supply, high assembly fault tolerance, and avoiding 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 atomization liquid bottle 20 connected to the atomizer 10 for supplying liquid. The atomization liquid bottle 20 is connected to a liquid inlet channel 141 to provide atomization liquid.

[0028] In one embodiment, Figure 1-Figure 6 As shown, an atomizer 10 is provided, including: a hollow liquid storage tank 11, an atomization 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, one end of which is a liquid inlet end 111, and the other end of which is an atomization outlet 112. It is understandable that the shape of the liquid storage tank 11 can be designed according to actual needs; the liquid inlet end 111 and the atomization outlet 112 can be arranged at different positions of the liquid storage tank 11 as needed.

[0030] The liquid storage part 13 is used to absorb the atomized liquid and is arranged in the liquid storage tank 11. Its shape matches the shape of the inner cavity of the liquid storage tank 11, so that it can be positioned in the liquid storage tank 11. As shown in the figure, in some embodiments, the liquid storage part 13 is provided with a mounting hole 131, and the atomizer core assembly 12 can be partially inserted into the mounting hole 131 and connected to the liquid storage part 13, so that the atomized liquid in the liquid storage part 13 is heated and atomized by the atomizer core assembly 12 to generate an aerosol. It can be understood that the connection method between the liquid storage part 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, and the user may inhale the aerosol generated in the atomization channel 1211 through the nozzle 19. The nozzle 19 and the sealing member 14 are respectively disposed at opposite ends of the liquid storage tank 11, and the replenishment direction of the atomized liquid is consistent with the outflow direction of the aerosol.

[0032] The sealing member 14 is sealingly disposed at the liquid inlet end 111 of the liquid storage bin 11, thereby sealing the liquid storage member 13 in the liquid storage bin 11. Figure 3 , 4 As shown, a liquid storage space 16 is formed between the end surfaces of the sealing member 14 and the liquid storage member 13. A through liquid inlet channel 141 is also provided on the sealing member 14, and the liquid inlet channel 141 is connected to 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 be used 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 bin 11, that is, when the aerosol outlet of the atomizer device is normally placed upward, the nozzle 19 is upward, the atomizer liquid bottle 20 and the liquid inlet end 111 are located at the bottom of the liquid storage bin 11, and the bottle mouth of the atomizer liquid bottle 20 is upward. When the liquid storage bin 11 needs to be replenished with liquid 2, the user needs to invert the atomizer device so that the bottle mouth of the atomizer liquid bottle 20 is downward.

[0035] When the atomizing device is inverted, the atomizing liquid bottle 20 is located above the liquid inlet channel 141, and the atomized liquid flows out from the outlet of the atomizing liquid bottle 20, flowing from top to bottom. At the beginning of the filling stage, 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 to 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 also 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 normally placed 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 is facing downward, and 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 less, and can also automatically block the liquid outlet 142 when the atomized liquid accumulated in the liquid storage space 16 reaches a certain amount, and the user is no longer required to frequently manually invert the atomizing device 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 is accumulated in the liquid storage space 16, the floating member 15 can move toward the liquid outlet 142 under the push of 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 action.

[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, such as PP or other plastics having a density lower than that of the atomized liquid.

[0039] In some other embodiments, the floating member 15 can also be made into a hollow member, that is, a cavity is formed inside the floating member 15, or the floating member 15 can also be made into a boat shape, so as to increase the buoyancy of the floating member 15, so that the average density of the floating member 15 is less than the density of the atomized liquid. In this case, the density of the material used for the floating member 15 can also be greater than, equal to, or less than the density of the atomized liquid. By increasing the buoyancy design of the floating member 15, the restrictions on the selection of materials for the floating member 15 can be reduced, and it has better 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 in the liquid inlet channel 141. When injecting liquid, the floating member 15 moves away from the liquid outlet 142 toward the liquid storage member 13. Due to the height limitation of the liquid storage space 16, the floating member 15 can be kept within the space where the liquid outlet 142 is located, thereby avoiding the defect that the floating member 15 is displaced and cannot block the liquid outlet 142 again.

[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 an enclosure around the liquid outlet 142, and the floating member 15 is set within the space range of the enclosure.

[0042] In one embodiment, if Figure 6 As shown, the end face of one side of the floating member 15 close to the liquid storage member 13 is provided with a liquid inlet groove 151 that runs through its periphery. When the end face of the floating member 15 contacts the end face of the liquid storage member 13, the liquid inlet groove 151 is provided so that the atomized liquid can enter between the two end faces to provide buoyancy and push the floating member 15 to move in the direction of 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, so as to provide 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 liquid inlet channel 141 near the liquid outlet 142 is a conical liquid outlet section 143; correspondingly, the outer periphery of the floating member 15 includes a conical surface that matches the conical shape of the liquid outlet section 143. Among them, the inner wall of the liquid outlet section 143 is a trumpet-shaped conical surface that is larger on the outside and smaller on the inside; correspondingly, the outer periphery of the floating member is a conical surface that matches the liquid outlet section 143. Through the cooperation of the conical structure, the floating member 15 can be better matched and centered in the liquid inlet channel 141, thereby forming a stable sealing effect. It can be understood that in other embodiments, the shapes of the liquid inlet channel 141 and the floating member 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 conical liquid inlet section 144 , so that the atomized liquid can 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 which are distributed and extend to the end surface of the liquid storage member 13; a liquid storage space 16 is formed in the space outside the protrusions 145. Through the provision of the 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 outside the protrusions 145 to form the liquid storage space 16, which ensures that the sealing member 14 presses the liquid storage member 13, and also avoids the situation where the sealing member 14 and the liquid storage member 13 are directly attached to each other and the liquid storage space 16 cannot be formed due to process deviation or structural deviation.

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

[0047] In one embodiment, the atomization core assembly 12 includes a heating element 121 provided with 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 and connected to a power source, and an atomization tube 124 disposed on the periphery of the liquid guide 122. It can be understood that the heating element 121, the liquid guide 122, the pin 123, the atomization tube 124, etc., can use various corresponding structures of 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, so as to isolate the atomization channel 1211 in the heating element 121 from the liquid storage space 16, and prevent 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 the contamination of the atomized liquid. It can be understood that the pin 123 can also pass through the seal 14 through the air inlet channel 146.

[0049] When working, the power supply is connected through the pin 123, so that the heating element 121 is heated. At this time, the liquid guide 122 transfers the atomized liquid in the liquid storage element 13 to the heating element 121, and the heating element 121 heats the atomized liquid, thereby generating aerosol in the atomization channel 1211. When the user inhales, the outside air is introduced through the air inlet channel 146, and then the aerosol in the atomization channel 1211 is taken 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 bin 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 transmitted 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 opens the bottle cap, the atomized liquid can directly flow 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 can be 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 atomization core assembly 12, thereby controlling the generation speed of the aerosol, which can 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 through 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; and the battery is mounted on the first base 173 and located on one side of the atomizer core assembly 12, so that the pin 123 can be easily connected 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 suction nozzle 19 and the liquid storage tank 11 to prevent leakage of aerosol. The airtight member 191 is provided with an air passage connecting the suction nozzle 19 and the atomization outlet 112. It is understandable that the suction nozzle 19 and the airtight member 191 may be connected by a snap-fit ​​structure; of course, they may also be fixedly connected by other connection methods.

[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, in which part of the atomizer 10 and the atomizing liquid bottle 20 except the suction nozzle 19 may be wrapped, so that the entire device is more beautiful and practical. It can be understood that the housing 30 may include two parts, one part wrapping the atomizer 10 and the other part wrapping the atomizing liquid bottle 20, so as to facilitate the 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 technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
