Description

Technical Field

[0001] The present invention relates to the field of atomization technology, in particular to an atomizer and an atomization device. Background Art

[0002] The atomizer is a device that can atomize the atomization matrix into an aerosol for users to use. It has been widely used in the electronic cigarette, medical, beauty and other industries. After leaving the factory, the atomizer has to go through a storage, transportation and shelf stage of several months or even a year. Under the temperature changes, humidity changes, air pressure changes and transportation conditions of the environment, the atomizer is prone to oil leakage. In order to solve the problem of oil leakage due to long-term storage before the atomizer is activated, the relevant technology adopts an oil core separation structure. Before the atomizer is activated, the oil core separation structure separates the atomizer core and the oil storage cavity, and the atomizer core does not enter the oil. When the user uses the atomizer for the first time, the atomizer core is activated to enter the oil. However, this oil core separation structure has certain defects: when the user uses it for the first time, the speed of the atomizer core entering the oil for the first time is slow, and the user needs to wait for a while before inhaling, that is, it needs time to moisten the core; even if the core is moistened in advance, the aroma of the first few puffs will be weak or the first few puffs will have a strange smell.

[0005] In some embodiments, in the second state, the first portion and the second end surface are separated from each other to form an air intake gap, and the air intake port, the air intake gap and the first central through hole are sequentially connected.

[0006] In some embodiments, the shell is provided with a boss, which is located in the cavity, arranged on the periphery of the air inlet and on the side of the first part away from the liquid-conducting liquid; the boss has a first through hole; in the second state, the first part abuts against the boss, and the air inlet, the first through hole, the air inlet gap and the first center through hole are sequentially connected.

Even if a small amount of atomized matrix leaks out from the gap between the hole wall of the first central through hole and the first sealing rod, the atomized matrix will not leak out. In the first state of the second sealing rod, since the first part of the second sealing rod abuts against the second end face of the liquid-conducting liquid of the atomizing core, the atomized matrix can be effectively reduced from leaking out from the second end face of the liquid-conducting liquid under the action of gravity.

[0035] 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.

[0036] 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).

[0037] In some embodiments, an atomization device is provided, which includes an atomizer and a power supply unit connected to the atomizer. The power supply unit and the atomizer can be detachably connected or integrally connected and difficult to disassemble. The power supply unit and the atomizer can form an electrical connection, and the power supply unit is used to provide power to the atomizer, and control the opening, closing and output power of the atomizer. The atomizer stores an atomization matrix, and the atomization matrix is ​​heated and atomized to generate an aerosol.

[0038] See also Figure 1 and Figure 2In some embodiments, an atomizer is provided, which includes a shell 1, an atomizing core 2, a first sealing rod 3 and a second sealing rod 4. The shell 1 is enclosed to form a cavity, and the shell 1 also has an air inlet 11 and an air outlet 12 respectively connected to the cavity. The air inlet 11 and the air outlet 12 respectively connect the cavity with the atmospheric environment outside the shell 1. The atomizing core 2 is arranged in the cavity. The cavity has a liquid storage chamber 10 for storing a liquid atomizing matrix, and the atomizing core 2 is connected to the liquid storage chamber 10. The atomizing core 2 can be electrically connected to the power supply unit, and the atomizing core 2 heats the atomizing matrix to atomize and generate an aerosol when powered on. External air enters the cavity from the air inlet 11, mixes with the aerosol generated by the atomizing core 2, and flows to the air outlet 12, and the mixture of aerosol and air flows out of the shell 1 from the air outlet 12 for the user to inhale.

[0039] The atomizing core 2 includes a hollow tubular liquid guide 21 and a heating element 22 disposed on the liquid guide 21. The liquid guide 21 has a first end surface 211 disposed opposite to the first end surface 212 (see Figure 2 The upper end surface of the liquid guide 21) and the second end surface 212 (refer to Figure 2 The liquid-conducting liquid 21 is connected to the lower end surface of the liquid-conducting liquid 21), and a first central through hole 210 that passes through the first end surface 211 and the second end surface 212. The first end surface 211 is arranged toward the air outlet 12, and the second end surface 212 is arranged toward the air inlet 11. The heating element 22 can be combined on the hole wall surface of the first central through hole 210. The liquid-conducting liquid 21 is connected to the liquid storage chamber 10, and the liquid-conducting liquid 21 conducts the atomized matrix in the liquid storage chamber 10 to the heating element 22. The heating element 22 heats the atomized matrix and atomizes it to generate aerosol when it is powered on. The generated aerosol can flow out from the first central through hole 210.

[0040] The atomizer has an activated state and an unactivated state. The unactivated state is the state of the atomizer from the time it leaves the factory to the time before the user first draws and uses it. In the unactivated state, the atomizer core 2 and the liquid storage chamber 10 are connected, and the atomizer core 2 is already in a saturated state of adsorbing the atomized matrix, so there is no need for a core lubrication time when the atomizer core 2 is activated.

[0041] See also Figure 2 In the unactivated state, the first sealing rod 3 is located on the side of the liquid guiding body 21 close to the gas outlet 12 (refer to Figure 2The upper side of the central guide liquid 21). One end of the first sealing rod 3 blocks the air outlet 12, and the other end of the first sealing rod 3 extends into the cavity and is embedded in the first central through hole 210. Specifically, one end of the first sealing rod 3 embedded in the first central through hole 210 fits or fits tightly with the hole wall of the first central through hole 210, which can effectively reduce the risk of the atomized matrix leaking out from the hole wall of the first central through hole 210. Even if a small amount of atomized matrix leaks out from the gap between the hole wall of the first central through hole 210 and the first sealing rod 3, the atomized matrix will not leak out because the first sealing rod 3 blocks the air outlet 12. When the atomizer core 2 needs to be activated, please refer to Figure 3 , the first sealing rod 3 is pulled out from the cavity in a direction close to the air outlet 12, so that the first sealing rod 3 and the first central through hole 210 are separated. After the first sealing rod 3 is pulled out, the air outlet 12 and the first central through hole 210 are connected, and the aerosol released from the first central through hole 210 can flow out of the housing 1 from the air outlet 12 for inhalation by the user.

[0042] See also Figure 2 In the unactivated state, the second sealing rod 4 is located on the side of the liquid guiding body 21 close to the air inlet 11 (refer to Figure 2 The second sealing rod 4 includes a first portion 41 and a second portion 42. The second sealing rod 4 has a first state and a second state. The first state of the second sealing rod 4 corresponds to the inactive state of the atomizer, preventing the atomized matrix stored in the atomizer core 2 from leaking outward; the second state of the second sealing rod 4 corresponds to the activated state of the atomizer. Figure 2 In the first state of the second sealing rod 4, the first portion 41 is located in the cavity and abuts against the second end surface 212 of the liquid guiding liquid 21, and the second portion 42 is connected to the first portion 41 and blocks the air inlet 11. Thus, the atomized matrix can be effectively reduced from leaking out from the second end surface 212 of the liquid guiding liquid 21 under the action of gravity. Even if a small amount of atomized matrix leaks out from the gap between the second end surface 212 and the first portion 41 of the second sealing rod 4, the atomized matrix will not leak out because the second portion 42 of the second sealing rod 4 blocks the air inlet 11. When the atomizer core 2 needs to be activated, please refer to Figure 3 and Figure 4 , pull out the second sealing rod 4 in the direction close to the air inlet 11, as shown in FIG. Figure 4As shown, the second sealing rod 4 reaches the second state, in which the first portion 41 is still located in the cavity, and is used to construct a part of the air inlet passage. The second portion 42 is separated from the first portion 41, and the second portion 42 withdraws from the air inlet 11. After the second portion 42 of the second sealing rod 4 is withdrawn, the air inlet 11 is connected to the first central through hole 210, and the outside air can enter the cavity from the air inlet 11 and flow to the first central through hole 210, and mix with the aerosol released from the first central through hole 210.

[0043] In summary, since one end of the first sealing rod 3 blocks the air outlet 12, and the other end of the first sealing rod 3 is embedded in the first central through hole 210 of the liquid guiding liquid 21 of the atomizer core 2, the risk of the atomized matrix seeping out from the hole wall of the first central through hole 210 can be effectively reduced. Even if a small amount of atomized matrix seeps out from the gap between the hole wall of the first central through hole 210 and the first sealing rod 3, the atomized matrix will not leak out. In the first state of the second sealing rod 4, since the first part 41 of the second sealing rod 4 abuts against the second end face 212 of the liquid guiding liquid 21 of the atomizer core 2, the atomized matrix can be effectively reduced from leaking out from the second end face 212 of the liquid guiding liquid 21 under the action of gravity. Even if a small amount of atomized matrix seeps out from the gap between the second end face 212 and the first part 41 of the second sealing rod 4, since the second part 42 of the second sealing rod 4 blocks the air inlet 11, the atomized matrix will not leak out. In the second state of the second sealing bar 4 , the first portion 41 is still located in the cavity, and a part of the air intake passage can be constructed.

[0044] As mentioned above, since the first central through hole 210 and the second end surface 212 of the liquid-conducting device 21 are respectively closed by the first sealing rod 3 and the second sealing rod 4, the sealing performance of the liquid-conducting device 21 is good. When the atomizer is not activated, the atomizing core 2 and the liquid storage chamber 10 can be connected, and the atomizing core 2 can be in a saturated state with adsorbed atomizing matrix. Therefore, when the atomizing core 2 is activated for the first time, no lubrication time is required, and there will be no weak aroma or peculiar smell in the first few puffs.

[0045] In addition, since the first sealing rod 3 and the second sealing rod 4 are respectively located on the opposite sides of the liquid guiding rod 21 of the atomizer core 2 (i.e., the side of the liquid guiding rod 21 close to the air outlet 12 and the side of the liquid guiding rod 21 close to the air inlet 11), when the atomizer core 2 needs to be activated, the user only needs to pull out the first sealing rod 3 and the second sealing rod 4 from the air outlet 12 and the air inlet 11 respectively. The length of each sealing rod will not be too long, and the withdrawal path of each sealing rod will not be too long, thereby making the withdrawal of the sealing rod more convenient and labor-saving.

[0046] like Figure 3As shown, before the second sealing rod 4 is converted from the first state to the second state, there is also an intermediate state. In this intermediate state, the second sealing rod 4 as a whole moves down a certain distance relative to the first state, so that the first part 41 and the second end face 212 are separated from each other to form an air intake gap 5, and the second part 42 is still connected to the first part 41, and the second part 42 has not yet been separated from the first part 41.

[0047] like Figure 4 and Figure 5 As shown, in some embodiments, in the second state, the first portion 41 and the second end surface 212 are separated from each other to form an air intake gap 5, and the air intake port 11, the air intake gap 5 and the first central through hole 210 are sequentially connected. Figure 5 Thus, the outside air can flow through the air inlet 11, the air inlet spacer 5 and the first central through hole 210 in sequence, and bring the aerosol generated by the atomization core 2 out to the air outlet 12.

[0048] like Figures 5 to 7 As shown, in some embodiments, the housing 1 is provided with a boss 6, which is located in the cavity, arranged at the periphery of the air inlet 11 and located on the side of the first portion 41 of the second sealing rod 4 away from the liquid guiding liquid 21 (i.e. Figure 5 The boss 6 has a third end face 63 disposed toward the first part 41, and an outer side face 65 and an inner side face 64 connected to the third end face 63. The boss 6 is provided with a first through hole 61 and a second through hole 62. The second through hole 62 passes through the third end face 63 to the air inlet 11, and the first through hole 61 passes through the outer side face 65 and the inner side face 64. The first through hole 61 is connected to the second through hole 62 in the radial direction. Specifically, as Figure 7 In the illustrated embodiment, the first through hole 61 may be a groove formed by being depressed downward from the third end surface 63, that is, the first through hole 61 may simultaneously penetrate the outer side surface 65, the inner side surface 64 and the third end surface 63. Alternatively, in some other embodiments, the first through hole 61 may only penetrate the outer side surface 65 and the inner side surface 64, but not the third end surface 63, and the first through hole 61 is a hole formed on the side wall of the boss 6.

[0049] like Figure 2 As shown, in the first state of the second sealing rod 4, the first portion 41 and the boss 6 are not in contact, and the second portion 42 passes through the second through hole 62 to block the air inlet 11. A portion of the second portion 42 may protrude outside the air inlet 11, so that the user can easily take the end of the second portion 42 away from the first portion 41. Figure 5As shown, in the second state of the second sealing rod 4, the first part 41 abuts against the boss 6, the first part 41 abuts against the third end face 63 and is partially embedded in the second through hole 62, and the part of the first part 41 embedded in the second through hole 62 plays a role in blocking the second through hole 62, and the first part 41 is thus fixed to the boss 6, so that the first part 41 is fixed directly below the liquid guide 21 of the atomizer core 2. Alternatively, in some other embodiments, the first part 41 may not contact the third end face 63, but is completely embedded in the second through hole 62 for fixing. The air inlet 11, the first through hole 61, the air inlet spacer 5 and the first central through hole 210 are connected in sequence. Please refer to the air flow path Figure 5 Thus, the outside air can flow through the air inlet 11, the first through hole 61, the air inlet spacer 5 and the first central through hole 210 in sequence, and bring the aerosol generated by the atomization core 2 out to the air outlet 12.

[0050] from Figure 5 It can be seen that in the second state of the second sealing rod 4, that is, in the activated state of the atomizer, after the first portion 41 and the second end surface 212 of the liquid-conducting liquid 21 are separated, the second end surface 212 of the liquid-conducting liquid 21 is exposed to the cavity, and the un-atomized and residual atomized matrix in the liquid-conducting liquid 21 will drip downward under the action of gravity. Figure 5 The upper surface of the first portion 41 in the liquid guiding liquid 21 can be used to collect the atomized matrix dripping from the second end surface 212 of the liquid guiding liquid 21. When the atomized matrix dripping on the first portion 41 is large in mass, it is guided to the periphery of the boss 6. In this way, the first portion 41 and the boss 6 respectively become obstacles for the atomized matrix dripping from the second end surface 212 of the liquid guiding liquid 21 to flow to the air inlet 11, thereby effectively reducing the risk of the atomized matrix dripping from the second end surface 212 of the liquid guiding liquid 21 leaking out from the air inlet 11, and the sealing performance is good.

[0051] Please also read Figure 2 , Figure 5 , Figure 8 and Fig. 9 In some embodiments, the housing 1 includes a housing body 13 and a bottom cover 14. The atomizer further includes a bracket 15. The housing body 13 and the bottom cover 14 are connected and together enclose a cavity, the air inlet 11 and the boss 6 are both formed on the bottom cover 14, and the bracket 15 is disposed in the cavity. The bracket 15 is provided with a second central through hole 150. Figure 2 As shown, the liquid-conducting body 21 is embedded and fixed in a part of the second central through hole 150. In the first state of the second sealing rod 4, the first portion 41 is embedded and fixed in another part of the second central through hole 150. Figure 5As shown, in the second state, the first portion 41 exits the second central through hole 150. Thus, the bracket 15 limits the liquid-conducting body 21 and the first portion 41 of the second sealing rod 4 in a circumferential direction, so that the first portion 41 can be kept in a position abutting against the second end surface 212 of the liquid-conducting body 21 in the first state.

[0052] Furthermore, in some embodiments, the first portion 41 of the second sealing rod 4 and the second central through hole 150 may be interference fit, thereby preventing the atomized matrix from leaking out from the gap between the hole wall of the first portion 41 and the second central through hole 150 to the greatest extent, and achieving better sealing performance.

[0053] like Figure 2 As shown, in some embodiments, the bracket 15 and the inner wall surface of the shell body 13 are together enclosed to form the liquid storage cavity 10. The bracket 15 is provided with a liquid guide channel 151 connected to the second central through hole 150, and the liquid guide channel 151 is connected to the liquid storage cavity 10 and the liquid guide body 21. Specifically, the end surface of the bracket 15 facing away from the bottom cover 14 (i.e. Figure 2 The upper end surface of the middle bracket 15 is concavely provided with a circle of liquid guiding grooves along the circumferential direction, and the liquid guiding grooves are inclined toward the guiding liquid 21 to form a liquid guiding channel 151. Alternatively, in some other embodiments, the liquid guiding channel 151 may also be in other structural forms, for example, the liquid guiding channel 151 may also extend downward from the end surface of the bracket 15 facing away from the bottom cover 14 and then bend toward the middle to guide the liquid 21. Thus, the bracket 15 may also play a role in connecting the liquid storage chamber 10 and the guiding liquid 21.

[0054] like Figure 2 As shown, in some embodiments, the housing 1 further includes a nozzle inner tube 16. The shell body 13 and the bottom cover 14 are connected and together enclose a cavity. The air inlet 11 is formed on the bottom cover 14. The nozzle inner tube 16 is connected to the shell body 13. One end of the nozzle inner tube 16 away from the shell body 13 extends into the cavity. The nozzle inner tube 16 is located directly above the liquid-conducting liquid 21. The bracket 15, the inner wall surface of the shell body 13 and the outer wall surface of the nozzle inner tube 16 facing the shell body 13 together enclose a liquid storage chamber 10. The inner wall surface of the nozzle inner tube 16 encloses an air outlet channel 160, which is connected to the first central through hole 210, and the air outlet 12 is formed at one end of the air outlet channel 160 away from the liquid-conducting liquid 21. The first sealing rod 3 is penetrated into the air outlet channel 160. When the atomizer is assembled before leaving the factory, the first sealing rod 3 is inserted into the nozzle inner tube 16 from the air inlet 11 to complete the sealing of the first central through hole 210. When the atomizer needs to be activated, the user only needs to pull out the first sealing rod 3 upwards.

[0055] Furthermore, in some embodiments, the first sealing rod 3 and the air outlet channel 160 may be interference fit, thereby preventing the atomized matrix from leaking out from the gap between the first sealing rod 3 and the inner wall surface of the air outlet channel 160 to the greatest extent, and the sealing performance is good.

[0056] like Figure 2 and Fig.10 As shown, in some embodiments, a groove 161 is formed at one end of the nozzle inner tube 16 away from the shell body 13, and the cross-sectional dimension of the groove 161 is larger than the cross-sectional dimension of the air outlet channel 160. It should be noted that the "cross-sectional dimension" referred to herein can refer to the transverse direction. Figure 2 and Fig.10 The end of the liquid guide 21 away from the second sealing rod 4 (that is, the end of the liquid guide 21 close to the gas outlet 12, refer to Fig.10 The upper end of the liquid guide 21 is fitted and fixed in the groove 161, and the first end face 211 of the liquid guide 21 abuts against the groove wall of the groove 161. As a result, the first end face 211 of the liquid guide 21 will be squeezed by the groove wall of the groove 161, and no matter the atomizer is in an activated state or an unactivated state, the leakage of the atomized matrix from the first end face 211 of the liquid guide 21 can be effectively reduced. Even if a small amount of atomized matrix leaks out from the gap between the first end face 211 and the groove wall of the groove 161, since the first sealing rod 3 and the air outlet channel 160 are interference-fitted, and the first sealing rod 3 blocks the air inlet 11, the atomized matrix will not leak out, and the sealing performance is good.

[0057] like Figure 5 , Figure 8 and Fig. 9 As shown, in some embodiments, the liquid-conducting material 21 is a fiber material, which is relatively soft and easily deformed. The atomizing core 2 also includes an atomizing tube 23, which is sleeved on the outer periphery of the liquid-conducting material 21 to support the liquid-conducting material 21, so as to prevent the liquid-conducting material 21 from being squeezed and deformed, thereby causing the atomized matrix to be squeezed out of the liquid-conducting material 21. A liquid inlet hole 230 is provided on the atomizing tube 23, and a part of the liquid-conducting material 21 is exposed to the liquid-conducting channel 151 through the liquid inlet hole 230. The liquid-conducting channel 151 on the bracket 15 is connected to the liquid inlet hole 230, so that the atomized matrix in the liquid storage chamber 10 can penetrate into the liquid-conducting material 21 through the liquid-conducting channel 151 and the liquid inlet hole 230, and finally contact the heating element 22.

[0058] like Figures 2 to 4As shown, in some embodiments, the first sealing rod 3 includes a rod body 31 and a plurality of sealing portions 32. The rod body 31 is inserted into the gas outlet channel 160, and one end of the rod body 31 is embedded in the first central through hole 210. The sealing portion 32 surrounds the outer peripheral surface of the rod body 31 along the circumferential direction. That is, the sealing portion 32 is an annular protrusion protruding relative to the rod body 31, and can be made of an elastic material. The sealing portion 32 and the gas outlet channel 160 are interference fit, and the cross-sectional size of the rod body 31 is smaller than the cross-sectional size of the gas outlet channel 160. That is, the first sealing rod 3 achieves sealing of the air outlet channel 160 through the sealing portion 32 circumferentially surrounding the outer circumferential surface of the rod body 31, and there is a gap between the rod body 31 and the air outlet channel 160, thereby reducing the direct contact area between the first sealing rod 3 and the air outlet channel 160 as much as possible, so that when the first sealing rod 3 is installed into the air outlet channel 160 or withdrawn from the air outlet channel 160, the friction between the first sealing rod 3 and the inner wall surface of the air outlet channel 160 can be reduced as much as possible, making the assembly and removal of the first sealing rod 3 smoother and more labor-saving.

[0059] In some embodiments, the first sealing rod 3 includes at least two sealing parts 32, wherein at least one sealing part 32 is a first sealing part, and at least one sealing part 32 is a second sealing part, and the cross-sectional size (e.g., diameter) of the second sealing part is smaller than the cross-sectional size (e.g., diameter) of the first sealing part. The first sealing part is located between the second sealing part and one end of the rod body 31 inserted into the first central through hole 210. Thus, the second sealing part is assembled to the air outlet channel 160 before the first sealing part, and by setting the diameter of the second sealing part smaller than the diameter of the first sealing part, it is beneficial for the rod body 31 and the second sealing part with a smaller interference to be assembled to the air outlet channel 160 smoothly first, and then the air outlet channel 160 is completely blocked by the first sealing part with a larger interference, which effectively improves the assembly smoothness of the first sealing rod 3 and the sealing performance of the first sealing rod 3 to the air outlet channel 160.

[0060] like Figures 2 to 4 As shown, in some embodiments, the first sealing rod 3 further includes a blocking portion 33. The blocking portion 33 is connected to an end of the rod body 31 away from the liquid-conducting body 21. The blocking portion 33 is at least partially located outside the gas outlet channel 160 and covers the gas outlet 12. Specifically, the cross-sectional dimension of the blocking portion 33 is larger than the cross-sectional dimension of the gas outlet 12 to cover the gas outlet 12. Further, the blocking portion 33 can be fitted with the surface of the shell body of the housing 1 at the periphery of the gas outlet 12. These arrangements are all conducive to the sealing of the first sealing rod 3 at the gas outlet 12, preventing the atomized matrix from leaking from the gas outlet 12 to the outside.

[0061] like Fig.11As shown, the second sealing rod 4 further includes a connecting portion 43, which is connected between the first portion 41 and the second portion 42, and the cross-sectional dimension of the connecting portion 43 is much smaller than the cross-sectional dimension of the first portion 41 and the cross-sectional dimension of the second portion 42. For example, the cross-sectional dimension of the connecting portion 43 can be smaller than half of the minimum cross-sectional dimension of the first portion 41; the cross-sectional dimension of the connecting portion 43 can be smaller than half of the minimum cross-sectional dimension of the second portion 42. The transverse direction referred to by the cross-sectional direction can refer to Fig.11 The CC direction indicated by the arrow in the middle. The CC is transversely perpendicular to the withdrawal direction of the second sealing rod 4. By setting the size difference between the connecting portion 43 and the first portion 41 and the second portion 42, the first portion 41 and the second portion 42 are easily broken. Figure 3 As shown, when the second sealing rod 4 moves down to the middle state, the first portion 41 abuts against the boss 6. At this time, the second sealing rod 4 is continued to be pulled, as shown in FIG. Figure 4 As shown, the first portion 41 is restricted by the boss 6 and will not move downward any further, while the second sealing rod 4 breaks at the connecting portion 43 , and the second portion 42 and the first portion 41 are separated from each other and exit the air inlet 11 .

[0062] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
