DETAILED DESCRIPTION

[0033] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0034] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0035] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0036] After the atomized liquid is heated and atomized, a substance that can be inhaled by the user is produced, such as an aerosol. As a suction structure, the nozzle 11 is usually made of plastic material. The heated aerosol flows to the nozzle 11 under the negative pressure generated by the user's inhalation. If it is not inhaled by the user in time, the aerosol will condense on the inner wall of the nozzle 11 to produce condensate. If the condensate is not recovered in time after hanging on the inner wall of the nozzle 11, it will affect the user's perception and experience, especially for large-capacity atomization devices. After hanging on the wall, the condensate may drip onto the atomization core 70, affecting the taste and mouthfeel of the suction. In order to recover the condensate at the nozzle 11 in time, the present application improves the structure of the nozzle 11, and the specific design of the nozzle 11 is as follows:

[0037] See also Figure 2 and Figure 4 In one embodiment of the present application, a suction nozzle 11 is provided for suction in an atomization structure. A drainage rib 113 is provided on the inner wall of the suction nozzle 11. The drainage rib 113 is used to drain the condensed liquid on the inner wall of the suction nozzle 11 to the liquid absorption part 40 in the atomization structure.

[0038] The atomization structure includes a liquid absorbing member 40, which is used to absorb the condensed liquid flowing down from the drainage ribs 113. The liquid absorbing member 40 is, for example, a liquid absorbing cotton. The nozzle 11 has a head end 11a and a tail end 11b, the head end 11a is located away from the liquid absorbing member 40 in the atomization structure, and the tail end 11b is located close to the liquid absorbing member 40 in the atomization structure. The length direction of the drainage ribs 113 is distributed between the head end 11a and the tail end 11b of the nozzle 11.

[0039] The drainage rib 113 is a protruding strip-shaped column. By arranging the drainage rib 113 on the inner wall of the suction nozzle 11, the condensate on the inner wall of the suction nozzle 11 can be drained, and the condensate can flow to the side of the liquid absorption part 40 in a timely and rapid manner, which is convenient for recovering the condensate at the suction nozzle 11.

[0040] More preferably, the drainage ribs 113 provided on the inner wall of the suction nozzle 11 are smooth curved surfaces, so as to facilitate rapid drainage of the condensate.

[0041] See also Figure 1-Figure 8 In another embodiment of the present application, an atomization structure (also commonly referred to as an atomizer) is provided, including: a housing 10, a liquid storage cup 20, a first sealing cover 30 and a liquid absorption component 40.

[0042] The housing 10 is provided with a nozzle 11, and a drainage rib 113 is provided on the inner wall of the nozzle 11. The liquid storage cup 20 is provided in the housing 10, and a liquid storage cavity for storing atomized liquid is formed in the liquid storage cup 20. The first sealing cover 30 is provided at one end of the liquid storage cup 20 close to the nozzle 11, and the first sealing cover 30 is provided with a receiving groove 31 at one end facing the nozzle 11. The liquid absorbing member 40 is placed in the receiving groove 31, and the liquid absorbing member 40 is used to absorb the condensed liquid flowing down from the drainage rib 113.

[0043] The atomization structure in the above embodiment is adopted, by arranging drainage ribs 113 on the inner wall of the suction nozzle 11, opening a storage groove 31 at one end of the first sealing cover 30 facing the suction nozzle 11, and placing a liquid absorbent member 40 in the storage groove 31. On the one hand, the condensed liquid on the inner wall of the suction nozzle 11 can be promptly and quickly drained to the liquid absorbent cotton through the drainage ribs 113 to avoid the accumulation of condensed liquid on the inner wall of the suction nozzle 11, or effectively reduce the content of condensed liquid on the inner wall of the suction nozzle 11. On the other hand, the liquid absorbent member 40 can cooperate to absorb the condensed liquid drained by the drainage ribs 113, so as to facilitate the timely recovery of the condensed liquid and avoid the condensed liquid from flowing to other places of the atomization structure, for example, avoiding the condensed liquid from flowing to the atomization core 70.

[0044] See also Figure 1 , Figure 3 , Figure 7-Figure 8 A mounting opening 12 is provided on the side wall of the housing 10 , and the positions of the mounting opening 12 and the receiving groove 31 correspond to each other, and the mounting opening 12 and the receiving groove 31 are communicated with each other.

[0045] The atomization structure further includes a fixing box 50, in which the liquid absorbing member 40 is placed. The fixing box 50 is detachably placed in the receiving groove 31 through the mounting opening 12. The fixing box 50 forms a first unobstructed area at one end facing the suction nozzle 11, and the condensed liquid passes through the first unobstructed area and drips onto the liquid absorbing member 40. The first unobstructed area can be any area as long as it can avoid the condensed liquid flowing down the inner wall of the suction nozzle 11, and the shape of the first obstructed area is not limited.

[0046] The first sealing cover 30 is provided with an air outlet 32, the liquid absorbing member 40 is provided with a first air vent 41, the fixing box 50 is provided with a second air vent 51, and the suction nozzle 11, the first air vent 41, the second air vent 51, the air outlet 32 ​​and the liquid storage chamber are interconnected.

[0047] Specifically, the fixed box 50 needs to be detachably placed in the storage groove 31 through the installation opening 12 opened on the side wall of the shell 10. Correspondingly, the groove wall of the storage groove 31 is not a complete circle of groove walls, and a corresponding notch needs to be provided, or no side wall is provided at the corresponding position of the storage groove 31 and the installation opening 12, so that the fixed box 50 can enter the storage groove 31, and then the liquid absorbent member 40 can be placed in the storage groove 31. For example, the storage groove 31 is a rectangular storage groove 31, the storage groove 31 has three side walls, the installation opening 12 is rectangular, and the liquid absorbent member 40 and the fixed box 50 are both rectangular. This shape combination can, on the one hand, make full use of the space in the shell 10, and on the other hand, increase the volume of the liquid absorbent member 40, so as to recover more condensate. In order to make full use of the space, that is, to increase the volume of the absorbent piece 40, the shape of the absorbent piece 40 is adapted to the shape inside the fixed box 50. For example, the absorbent cotton and the side wall of the fixed box 50 are interference fit, and an interference margin of 0.2mm-0.5mm is left between the absorbent cotton and the side wall of the fixed box 50. At the same time, it is also convenient for the absorbent piece 40 to be firmly clamped in the fixed box 50.

[0048] The use principle of the fixed box 50 is as follows Figure 8 As shown, a drawer-like pulling method is used to realize a detachable connection between the fixed box 50 and the storage slot 31. Similarly, the sizes of the fixed box 50, the mounting port 12 and the storage slot 31 are adapted to each other. However, since the fixed box 50 needs to be pulled and moved relative to the mounting port 12 and the storage slot 31, a certain gap margin can be left between the fixed box 50 and the mounting port 12 and the storage slot 31. For example, a gap space of 0.1mm-0.5mm is left between the fixed box 50 and the mounting port 12.

[0049] In other embodiments, the shapes of the installation opening 12, the receiving groove 31, the liquid absorbent member 40 and the fixing box 50 may also be other types. Taking the receiving groove 31 as an example, the receiving groove 31 is an elliptical or approximately elliptical structure.

[0050] See also Figure 3 and Figure 6 Specifically, in the embodiment of the present application, the fixing box 50 includes a bottom plate 52, a top plate 53, a first side plate 54, and a pair of second side plates 55. The bottom plate 52, the top plate 53, the first side plate 54, and the pair of second side plates 55 form a wrapping surface at an end away from the receiving groove 31, and the wrapping surface is used to wrap the end of the absorbent member 40 away from the receiving groove 31. The bottom plate 52 is provided with a second vent 51, and the top plate 53 and the second vent 51 are staggered along the axial direction perpendicular to the suction nozzle 11.

[0051] For the convenience of describing the specific structure of the fixed box 50, the direction perpendicular to the first side plate 54 is the first direction, the direction parallel to the first side plate 54 is the second direction, and both the first direction and the second direction are perpendicular to the axial direction of the suction nozzle 11. The bottom plate 52 and the top plate 53 are spaced and arranged in parallel, and the ends of the bottom plate 52 and the top plate 53 away from the storage groove 31 are flush, the first side plate 54 is located at the end of the bottom plate 52 away from the storage groove 31, and the first side plate 54 is fixedly connected to the bottom plate 52 and the top plate 53 respectively, and a pair of second side plates 55 are fixedly connected to both sides of the bottom plate 52 along the second direction, and the second side plates 55 are also fixedly connected to the top plate 53 and the first side plate 54 respectively.

[0052] The bottom plate 52, the top plate 53, the first side plate 54 and the second side plate 55 form a relatively closed wrapping surface to ensure the sealing of the storage groove 31. If the storage groove 31 is connected to the outside through the installation port 12, it is not convenient to create a negative pressure environment when the user sucks the suction nozzle 11, which affects the smoothness of sucking aerosol.

[0053] More preferably, along the first direction, the size of the bottom plate 52 is consistent with the size of the second side plate 55. In this way, combined with the wrapping surface, it can provide a storage effect for the absorbent component 40 on the fixed box 50, better centrally distribute the condensate recovered from the absorbent component 40, and avoid leakage.

[0054] The atomization structure designed in the present application includes a liquid absorbent part 40, which can recover the condensed liquid on the inner wall of the suction nozzle 11. The liquid absorbent part 40 in the atomization structure can be disassembled and replaced by cooperating with the storage groove 31, the installation port 12 and the fixing box 50. When the liquid absorbent part 40 can be disassembled, firstly, the recovery effect of the liquid absorbent part 40 on the condensed liquid can be guaranteed by timely replacing the liquid absorbent part 40. Even if the liquid absorbent part 40 is limited by the product volume and the amount of liquid absorbed is limited, the condensed liquid recovery effect can be guaranteed by timely replacing the liquid absorbent part 40; secondly, by replacing the liquid absorbent part 40, it can be avoided that the condensed liquid accumulates in the liquid absorbent part 40 for a long time and becomes smelly or produces peculiar smell.

[0055] Preferably, the fixing box 50 is made of a transparent material. After the absorbent 40 absorbs the condensed liquid, the color of the absorbent 40 will change. The more condensed liquid the absorbent 40 absorbs, the greater or more obvious the color change of the absorbent 40 will be. At this time, the transparent fixing box 50 can assist the user in determining whether the absorbent 40 needs to be replaced. In other embodiments, the fixing box 50 can also be made of a non-transparent material. In this case, the user can determine whether the absorbent 40 needs to be replaced based on the experience of suction or taste.

[0056] See also Figure 6-Figure 8In an embodiment of the present application, a sealing ring 56 is provided between the mounting port 12 and the wrapping surface, and the sealing ring 56 abuts against the mounting port 12 and the wrapping surface respectively. For example, the sealing ring 56 is rubber-wrapped and fixed to the outer periphery of the wrapping surface, and the sealing ring 56 is used to ensure the sealing of the space within the mounting port 12 of the outer shell 10. Alternatively, the sealing ring 56 is rubber-wrapped and fixed in the mounting port 12. Similarly, the sealing of the space within the mounting port 12 of the outer shell 10 can also be ensured, thereby ensuring the smoothness of the user's aerosol inhalation. At the same time, the fixing box 50 can also be detachably fixed to the outer shell 10 by the sealing ring 56 abutting against the mounting port 12 and the wrapping surface respectively. In other embodiments, the fixing box 50 can also be fixed to the outer shell 10 by means of magnetism, snap-fit, etc., which is not limited in this application.

[0057] In the embodiment of the present application, the fixing box 50 is further provided with a stopper 57, which is used to abut against the inner wall of the housing 10 to limit the moving position of the fixing box 50. For example, the stopper 57 is symmetrically fixed on the side of the pair of second side plates 55 that are away from each other. After the fixing box 50 is pulled outward to a certain range, the stopper 57 and the inside of the housing 10 are blocked to prevent the fixing box 50 from being separated from the housing 10. In this way, each time the liquid absorbent member 40 is replaced, the fixing box 50 can be pulled out without repeatedly aligning and installing the fixing box 50, thereby simplifying the replacement operation of the liquid absorbent member 40. Specifically, the stopper 57 can be a column, a plate, etc.

[0058] The atomization structure further includes a disassembly portion 13 for assisting in disassembly of the fixed box 50. The disassembly portion 13 may be a handle mounted on the first side plate 54 of the fixed box 50, or the disassembly portion 13 may be a disassembly position provided on the housing 10 at the mounting opening 12, for example Figure 7 The upper semi-arc-shaped disassembly position provides the user with operating space, making it easier to apply force to disassemble the fixing box 50 .

[0059] See also Figure 1-Figure 3In the embodiment of the present application, the atomization structure also includes a liquid storage part 60 and an atomization core 70, and the atomization core 70 includes an atomization tube 71, a liquid guide part 72 and a heating element (not shown). The liquid storage part 60 is placed in the liquid storage cavity, and the liquid storage part 60 is used to absorb the atomized liquid in the liquid storage cavity. The liquid storage part 60 is, for example, a liquid storage cotton. An atomization channel 61 is formed on the liquid storage part 60, the atomization tube 71 is sleeved in the atomization channel 61, and the liquid guide part 72 is sleeved in the atomization tube 71. The liquid guide part 72 can be an annular cylinder, and the liquid guide part 72 and the liquid storage part 60 are contacted through the opening in the side wall of the atomization tube 71, or, in addition to the annular cylinder, the liquid guide part 72 can also include a block protruding into the liquid storage part 60, and the block is in contact with the liquid storage part 60. The liquid guide part 72 is used to absorb and conduct the atomized liquid on the liquid storage part 60. For example, the liquid guide part 72 is a liquid guide ceramic. The heating element is fixed to the inner wall of the liquid guiding element 72 . The heating element may be in the shape of a mesh, a filament, a sheet, etc. The heating element is used to heat the atomized liquid on the inner wall of the atomized liquid guiding element 72 .

[0060] The atomization structure also includes a second sealing cover 80, which is arranged at one end of the liquid storage cup 20 away from the suction nozzle 11. The liquid storage cup 20, the first sealing cover 30 and the second sealing cover 80 enclose a liquid storage cavity. The second sealing cover 80 is provided with a docking column 81 at one end facing the liquid storage cavity. The docking column 81 is sleeved with the atomization tube 71, and an air inlet is formed in the docking column 81. When the user sucks the suction nozzle 11, the external gas flows into the atomization tube 71 through the air inlet, and flows to the side of the suction nozzle 11 together with the heated and atomized atomized liquid through the air outlet 32, the second vent 51 and the first vent 41. The first sealing cover 30 and the second sealing cover 80 are, for example, silicone sealing covers, which are convenient for both sealing and detachable connection with the liquid storage cup 20.

[0061] See also Figure 2-Figure 3 One end of the atomizer tube 71 passes through the air outlet 32, the second air vent 51 and the first air vent 41 in sequence and connects with the mouthpiece 11. In this way, the atomizer tube 71 is relatively close to the mouthpiece 11, which facilitates the gas (containing aerosol) in the atomizer tube 71 to flow into the mouthpiece 11 in a shorter path and more concentratedly, thereby ensuring the user's puffing effect and puffing experience.

[0062] To facilitate the detachable movement of the fixed box 50 containing the liquid absorbing member 40 in the storage groove 31, the first vent 41 and the second vent 51 are both U-shaped openings, and the first vent 41 and the second vent 51 are both plugged into the atomizing tube 71 outside the liquid storage cavity.

[0063] The size of the U-shaped opening is adapted to the size of the atomizer tube 71. Usually, the atomizer tube 71 is a cylindrical tube. Correspondingly, the end of the U-shaped opening away from the mounting port 12 is used for the atomizer tube 71 to be inserted into the U-shaped opening. The shape of the end of the U-shaped opening close to the mounting port 12 is adapted to the outer wall shape of the atomizer tube 71 to increase the area where the side wall of the U-shaped opening fits the side wall of the atomizer tube 71. In this way, for the liquid absorbent 40, the space inside the housing 10 can be fully utilized to increase the volume of the liquid absorbent 40 and ensure the liquid absorption amount of the liquid absorbent 40. For the fixed box 50, the second vent 51 and the first vent 41 are consistent in shape and size, which better wraps the liquid absorbent 40 so that the condensed liquid in the liquid absorbent 40 is concentratedly distributed.

[0064] When the inner wall of the nozzle 11 is not provided with drainage ribs 113, and the condensate flows from the inner wall of the nozzle 11 to the liquid absorbing member 40 only by its own gravity, enough condensate needs to be gathered or accumulated on the inner wall of the nozzle 11 so that the condensate can flow to the liquid absorbing member 40. The recovery speed of the condensate in this process is limited. After the drainage ribs 113 are arranged on the inner wall of the suction nozzle 11, the drainage effect of the drainage ribs 113 can assist the condensate to flow quickly to the liquid absorption part 40. At this time, the condensate does not need to accumulate to a certain amount on the inner wall of the suction nozzle 11 before it can flow. However, it should be noted that the number of drainage ribs 113 cannot be too small, otherwise the drainage effect will be limited; the number of drainage ribs 113 cannot be too large, otherwise multiple drainage ribs 113 will occupy a large area on the inner wall of the suction nozzle 11, and the inner wall area of ​​the suction nozzle 11 without the drainage ribs 113 will become smaller. When the inner wall area of ​​the suction nozzle 11 without the drainage ribs 113 is relatively small, the condensate on the inner wall of the suction nozzle 11 is not easy to gather, and thus the advantages of the drainage ribs 113 cannot be better utilized.

[0065] Based on this, in the embodiment of the present application, the number of the drainage ribs 113 is configured to be 2-4. Within this range, the convergence effect of the condensate on the inner wall of the suction nozzle 11 can be guaranteed, and the function of the drainage ribs 113 can also be brought into play.

[0066] More preferably, the nozzle 11 includes an inner tube 111 and an outer tube 112 connected to each other, a drainage rib 113 is provided on the inner wall of the inner tube 111, and the end of the outer tube 112 is fixed to the shell wall of the outer shell 10. For ease of processing, the nozzle 11 and the outer shell 10 are an integral structure. The end of the inner tube 111 close to the liquid-absorbing member 40 is an inclined cross section, and a lowest point 11c and a highest point 11d are formed on the inclined cross section, the lowest point 11c is located on the side close to the installation port 12, and the highest point 11d is located on the side away from the installation port 12.

[0067] The end of the inner tube 111 close to the liquid absorbent 40 is an inclined cross-section, which can further drain the condensate on the inner wall of the nozzle 11, thereby ensuring the recovery speed of the condensate. Since the liquid absorbent 40 and the fixed box 50 are fixed in the storage groove 31 in a pull-out manner, the first vent 41 and the second vent 51 need to be plugged into the atomizer tube 71. The first vent 41 is not provided with the liquid absorbent 40, that is, the first vent 41 of the atomizer tube 71 away from the installation port 12 is vacant. At this time, the lowest point 11c is located on the side close to the installation port 12, and the highest point 11d is located on the side away from the installation port 12, which can ensure that the condensate is drained to the side with the liquid absorbent 40, thereby ensuring the condensate recovery effect.

[0068] See also Figure 2 Specifically, one end of the atomizer tube 71 located outside the liquid storage cavity is sleeved inside the inner tube 111. On the one hand, the aerosol flowing out of the atomizer tube 71 can flow directly to the inner tube 111 of the suction nozzle 11, thereby preventing the aerosol from diffusing to other spaces in the outer shell 10 and ensuring the suction effect. On the other hand, the atomizer tube 71 is placed inside the inner tube 111, which greatly reduces the probability of condensed liquid on the inner wall of the inner tube 111 dripping into the atomizer tube 71.

[0069] The absorbent member 40 and the lowest point 11c of the inner tube 111 are spaced apart, so that the condensate can drip onto the absorbent member 40 through the lowest point 11c of the inclined section, thereby ensuring the flow guiding advantage of the inclined section on the inner tube 111. If there is no space margin between the absorbent member 40 and the inner tube 111, due to the possible machining tolerance between the inner tube 111 of the nozzle 11 and the absorbent member 40, the absorbent member 40 and the lowest point 11c of the inner tube 111 may abut against each other, and the flow guiding advantage of the inclined section of the inner tube 111 cannot be brought into play.

[0070] More preferably, the inner wall of the suction nozzle 11 (inner tube 111) is divided into a first area and a second area, the first area is located on the side close to the installation port 12, and the second area is located on the side away from the installation port 12, and drainage ribs 113 are provided on the inner wall of the suction nozzle 11 in the first area. The drainage ribs 113 are provided on the inner wall of the inner tube 111 in the first area close to the installation port 12, so that the condensate can be collected to the lowest point 11c at a faster speed.

[0071] For example Figure 5As shown, the first area and the second area are two areas that are directly opposite to each other on the inner wall of the inner tube 111, and the number of drainage ribs 113 is configured as three, of which two drainage ribs 113 are located at the two ends of the first area in the circumferential direction, and a drainage rib 113 is provided on the first area between the two drainage ribs 113. When the user sucks the suction nozzle 11, when the condensate on the inner wall of the inner tube 111 reaches a certain amount, the three drainage ribs 113 will play a drainage role and carry most of the surrounding condensate down along the inner wall. Since the end of the inner tube 111 close to the liquid absorbent 40 is provided with an inclined section, the inclined section will collect the condensate flowing down the inner wall of the inner tube 111 to the lowest point 11c, which is the point that directly contacts the liquid absorbent 40, and finally achieves the effect of drainage and collection of condensate.

[0072] More preferably, along the axial direction of the suction nozzle 11, the thickness of the liquid absorbent member 40 is less than the thickness of the storage groove 31. In this way, the liquid absorbent member 40 in the storage groove 31 has the effect of being recessed into the storage groove 31. Even if the liquid absorbent member 40 is later full of condensed liquid, the recessed space in the storage groove 31 can further store the condensed liquid, thereby preventing the condensed liquid from leaking to other places in the housing 10.

[0073] The atomization structure designed in the present application can recover the condensate by adding drainage ribs 113 at the position of the suction nozzle 11, and is designed with a detachable liquid absorbent part 40 to effectively recycle and recover the condensate, thereby preventing the condensate from affecting the taste and mouthfeel of the atomization structure. The condensation recovery structure at the suction nozzle 11 is combined with the detachable and replaceable liquid absorbent part 40 structure to prevent the condensate from flowing back to the atomization core 70 or the problem of poor experience caused by a large amount of condensate remaining in the liquid absorbent part 40 for a long time. The atomization structure can be suitable for a small-capacity atomization structure, such as a liquid storage volume of 5ml-6ml, and can also be used for a large-capacity atomization structure, such as a liquid storage volume of 10ml-20ml. For a large-capacity atomization structure, the number of suctions is large, and a detachable and replaceable structural design of the liquid absorbent part 40 is required.

[0074] See also Figure 1-Figure 8 In another embodiment of the present application, an atomization device is provided, including an atomization structure and a power supply structure. The atomization structure is the atomization structure in the above embodiment, and the power supply structure includes a battery cell 90 and a circuit board 100. The battery cell 90 is used to provide electrical energy to the atomization core 70 in the atomization structure, and the circuit board 100 is used to control the working state of the atomization core 70. The atomization device also includes a bottom cover 110, and the battery cell 90 and the circuit board 100 are fixed in the bottom cover 110. The bottom cover 110 is fixedly connected to the outer shell 10 in the atomization structure. Among them, the atomization device is a disposable atomization device or a cartridge-changing atomization device. When the atomization device is a cartridge-changing atomization device, the atomization structure and the power supply structure are detachably connected, for example, the atomization structure and the power supply structure are detachably connected through the outer shell 10 and the bottom cover 110.
