Description

[0002] The present disclosure relates to the field of atomization technologies, and in particular, to an atomizer and an electronic atomizing device. BACKGROUND

[0003] An existing electronic atomizing device usually includes a detachable host and an atomizer. A cell is arranged inside the host, and is configured to supply power to the atomizer. Generally, a start switch, such as an airflow sensor, is arranged on the host, and is configured to start the host for supplying power to the atomizer when a user inhales and uses the electronic atomizing device.

[0004] However, in the existing electronic atomizing device, a start airflow channel in communication with the airflow sensor is usually in direct communication with an air inlet groove defined on the end of the host facing toward the atomizer, and air from the outside flows into an inhalation channel defined in the atomizer through the air inlet groove. Therefore, when liquid, such as condensate or the like, exists in the inhalation channel, the liquid is very likely to enter the start airflow channel and cause damage to the airflow sensor. Moreover, once the inhalation channel is blocked by an atomizing substrate with high viscosity, the electronic atomizing device is very likely to fail and be scrapped, resulting in a high failure rate of existing electronic atomizing device.

According to another aspect of the invention, there is provided an electronic atomizing device, comprising a host and an atomizer as described above, wherein the host is connected to the atomizer, and an end of the start air tube away from a suction nozzle opening is in communication with the start switch on the host.

Those skilled explicitly and implicitly understand that the embodiments described in the present disclosure can be combined with other embodiments.

[0019] The present disclosure provides an electronic atomizing device 300. Referring to FIG. 1 to FIG. 3, FIG. 1 is a schematic structural view of an embodiment of an electronic atomizing device according to the present disclosure, FIG. 2 is a schematic exploded structural view of the electronic atomizing device shown in FIG. 1, and FIG. 3 is a schematic cross-sectional structural view of the electronic atomizing device shown in FIG. 1.

[0020] The electronic atomizing device 300 includes an atomizer 100 and a host 200. The host 200 may be detachably connected to the atomizer 100. That is, the electronic atomizing device 300 may be a split device. In some embodiments, the host 200 is non-detachably connected to the atomizer 100. That is, the electronic atomizing device 300 is an integrated device. For example, the atomizer and the host share some components.

[0021] The host 200 includes a battery 202, a start switch 201, and a control component 203. The control component 203 is electrically connected to the battery 202 and the start switch 201, and is configured to supply power to the atomizer 100. The start switch 201 may be an airflow sensor, other air pressure sensor, or the like. The start switch 201 transmits a signal to the control component 203 when sensing inhalation of a user. The control component 203 starts the host 200 based on the signal to supply power to the atomizer 100, so as to provide energy required by atomization of the atomizer 100. When the signal disappears or changes, the control component 203 stops supplying power to the atomizer 100.

[0022] As shown in FIG. 1 to FIG. 3, the atomizer 100 includes a suction nozzle opening 101, a liquid storage cavity 102, an inhalation channel 103 passing through the liquid storage cavity 102 and in communication with the suction nozzle opening 101, and a start air tube 21 passing through the liquid storage cavity 102. The start air tube 21 is detachably arranged, and the end of the start air tube 21 close to the suction nozzle opening 101 is in communication with the end of the inhalation channel 103 close to the suction nozzle opening 101. The end of the inhalation channel 103 away from the suction nozzle opening 101 is in communication with the external atmosphere, the end of the start air tube 21 away from the suction nozzle opening 101 is configured to communicate with the start switch 201 in the host 200, and a channel communicating the inhalation channel 103 with the external atmosphere is spaced apart from a channel communicating the start air tube 21 with the start switch 201, that is, the two channels are independent of each other.

[0023] In some embodiments, the atomizer 100 may include a body 110 and the start air tube 21 arranged in the body 110. The body 110 includes an inhalation channel 103 in communication with the suction nozzle opening 101. One end of the start air tube 21 is in communication with one end of the inhalation channel 103, the other end of the inhalation channel 103 is in communication with the external atmosphere, the other end of the start air tube 21 is configured to communicate with a start switch 201 on a host 200, and a channel communicating the start air tube 21 with the start switch 201 is spaced apart from a channel communicating the inhalation channel 103 with the external atmosphere.

[0024] The body is an integrated structure, in which the suction nozzle opening 101, the liquid storage cavity 102, and the inhalation channel 103 are formed, and the channel communicating the start air tube 21 with the end of the inhalation channel 103 close to the suction nozzle opening 101 is further formed. In some embodiments, the end of the start air tube 21 close to the suction nozzle opening 101 is in direct communication with the end of the inhalation channel 103 close to the suction nozzle opening 101. The start air tube 21 is detachably connected to the body, and passes through the liquid storage cavity 102.

[0025] In another embodiment, the atomizer 100 may include the body 110, an end cap, and the start air tube 21. The body 110 is an integrated structure, in which the suction nozzle opening 101, an accommodating space, and the inhalation channel 103 are formed. The end cap is detachably connected to one end of the body 110 to cover the accommodating space, defines a liquid storage cavity 102, and further connect to one end of the inhalation channel 103. One end of the start air tube 21 passes through the accommodating space to be detachably connected to the other end of the body 110, and the other end of the start air tube 21 is detachably connected to the end cap.

[0026] The atomizer 100 may also be other structures, which are not exemplified in the present disclosure. All structures that the atomizer 100 mentioned above is defined fall within the protection scope of the present disclosure.

[0027] The atomizer 100 is connected to the host 200, in this way, the end of the start air tube 21 away from the suction nozzle opening 101 is in communication with the start switch 201 on the host 200. The inhalation channel 103 may be in communication with the external atmosphere through the host 200 or may be in communication with the external atmosphere without assistance of the host 200.

[0028] In the present disclosure, the independent start air tube 21 passing through a liquid storage cavity 102 is arranged to form a start airflow channel that is not shared with the inhalation channel 103, so as to avoid the problem that an atomizer 100 cannot be started after the inhalation channel 103 is blocked. In addition, the end of the start air tube 21 close to the suction nozzle opening 101 is in communication with the end of the inhalation channel 103 close to the suction nozzle opening 101, that is, the start air tube 21 is also in direct communication with the suction nozzle opening 101. Moreover, this position is located on the side of the liquid storage cavity 102 close to the suction nozzle opening 101, and being close to the suction nozzle opening 101 prevents this position from being easily blocked by aerosol condensate. Therefore, even if the inhalation channel 103 is blocked, during inhalation, a user can still start the atomizer 100 through the start air tube 21 for heating. After the heating is started, an atomization core 30 inside the inhalation channel 103 heats up for atomization, and reduce the viscosity of an atomizing substrate that blocks the inhalation channel 103 to enable the atomizing substrate flow away or atomized. Therefore, a bad situation that inhalation channel 103 is blocked is eliminated, and the atomizer 100 can return to normal and continue to be used, thereby improving the reliability of the atomizer 100.

[0029] In the existing solutions, usually, a liquid storage cavity, an inhalation channel, and a start airflow channel are directly formed in a housing of an atomizer, resulting in high difficulty of mold making and complex processes of the housing. To improve the yield rate of mold making, usually, the pore diameter of the start airflow channel is made largely, and the pore dimeter is larger than 2 mm. To ensure the strength of the pore wall of the start airflow channel, the wall thickness of the start airflow channel is also made largely, and the wall thickness is larger than 0.5 mm. However, during trial production of the mold, a needle on the mold is likely to be crooked during high-temperature gel filling, resulting in a high risk and a poor yield rate. In addition, because of the large pore size and wall thickness of the start airflow channel, the start airflow channel occupies a large volume of the liquid storage cavity, thereby making a serious impact on the capacity of the liquid storage cavity.

[0030] Compared with the existing solution that a liquid storage cavity, a inhalation channel, and a start airflow channel are directly formed on a housing of atomizer, defines that the start air tube 21 of the present disclosure is detachably arranged, that is, the start air tube 21 can be independently manufactured as a separate component, in this way, the start air tube can be miniaturized, which can significantly reduce the manufacturing difficulty of other components in the atomizer 100 and improve the yield rate of the atomizer 100. In addition, the miniaturized start air tube 21 occupies less space in the liquid storage cavity 102, and has less impact on the capacity of the liquid storage cavity 102.

[0031] In some embodiments, the start air tube 21 is a metal tube, for example, a stainless steel tube, an aluminum alloy tube, or a titanium alloy tube, etc., which has high strength and may be easily manufactured into a start air tube 21 with a small tube diameter and a small wall thickness. That is, the tube diameter of the start air tube 21 may be less than or equal to 2.0 mm, and the wall thickness of the start air tube 21 may be less than or equal to 0.5 mm.

[0032] The tube diameter of the start air tube 21 is greater than or equal to 0.6 mm and less than or equal to 2.0 mm, and the wall thickness of the start air tube 21 is greater than or equal to 0.1 mm and less than or equal to 0.3 mm. The start air tube 21 is independently arranged and made of a metal tube. The start air tube 21 can be easily made into a size that a start airflow channel in the existing solutions cannot reach. Because of the high strength of the start air tube 21, the wall thickness may also be made small, in this way, the start air tube 21 occupies less space of the liquid storage cavity 102.

[0033] The tube diameter of the start air tube 21 may be 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, or 2.0 mm. The wall thickness of the start air tube 21 may be 0.1 mm, 0.12 mm, 0.14 mm, 0.16 mm, 0.18 mm, 0.2 mm, 0.22 mm, 0.24 mm, 0.26 mm, 0.28 mm, or 0.3 mm.

[0034] In some embodiments, the start air tube 21 may also be a high-strength plastic tube or the like, which is not specifically limited in the present disclosure.

[0035] Referring to FIG. 2 to FIG. 4, FIG. 4 is a schematic cross-sectional structural view of an atomizer in the electronic atomizing device shown in FIG. 2.

[0036] In some embodiments, the atomizer 100 includes a suction nozzle 10, a shell 22, an atomization air tube 23, and the start air tube 21. The two ends of the atomization air tube 23 are correspondingly connected to the two ends of the shell 22. The start air tube 21 is detachably connected to the two ends of the shell 22, and both the atomization air tube 23 and the start air tube 21 pass through the liquid storage cavity 102 of the shell 22. The atomization air tube 23 is defined in an inhalation channel 103 communicating with the suction nozzle opening 101. The suction nozzle 10 is defined in the suction nozzle opening 101, the suction nozzle 10 is connected to the shell 22, the suction nozzle opening 101 is in communication with the atomization air tube 23, and a communication airway 104 is defined on the suction nozzle 10 and one end of the shell 22, and the communication airflow channel 104 communicates the atomization air tube 23 with the end of the start air tube 21 close to the suction nozzle 10.

[0037] The suction nozzle 10 is detachably connected to the shell 22. For example, the connection manner includes a clamped connection manner, a screwed connection manner, or being connected by a fastener. The fastener may be a screw, a pin, or the like. After the connection is completed. The suction nozzle 10 and the shell 22 jointly form the communication airflow channel 104, in this way, the end of the atomization air tube 23 close to the suction nozzle 10 is in communication with the end of the start air tube 21 close to the suction nozzle 10 through the communication airflow channel 104.

[0038] In some embodiments, the suction nozzle 10 may also be connected to the shell 22 in a non-detachable connection manner such as welding, bonding, or hot-column hot-melt connection.

[0039] The atomization air tube 23 may also be connected to the shell 22 detachably or non-detachably, which is not limited in the present disclosure.

[0040] As shown in FIG. 4, the suction nozzle 10 includes a first housing 12 and a second housing 14 arranged on the inner side of the first housing 12. A cavity 13 is defined between the first housing 12 and the second housing 14, the suction nozzle opening 101 is defined on the second housing 14, and at least one transition opening 105 in communication with the cavity 13 and the suction nozzle opening 101 is defined on the end of the second housing 14 and / or the shell 22 close to the suction nozzle opening 101. The first housing 12 is detachably connected to the shell 22, and one end of the shell 22 covers the cavity 13 to define and form the communication airflow channel 104. The end of the start air tube 21 close to the suction nozzle opening 101 extends into the cavity 13.

[0041] That is, the suction nozzle 10 is a shell structure, which may be manufactured by injection molding or die-casting. The communication airflow channel 104 includes the cavity 13 and the transition opening 105. In other embodiments, the communication airflow channel 104 may be a groove structure or a hole structure on the suction nozzle 10. The first housing 12 and the second housing 14 may also be manufactured independently, and then be connected to form the suction nozzle 10, which is not specifically limited in the present disclosure.

[0042] As shown in FIG. 4, the shell 22 includes a barrel portion 220 and a first end portion 222 and a second end portion 224 respectively connected to the two ends of the barrel portion 220. At least one of the first end portion 222 and the second end portion 224 is detachably connected to barrel portion 220, and defines the liquid storage cavity 102.

[0043] In some embodiments, the atomization air tube 23 is detachably connected to the two ends of the shell 22. In case where the atomization air tube 23 and the start air tube 21 pass through the liquid storage cavity 102, and are connected to the first end portion 222 or second end portion 224, one of the first end portion 222 or second end portion 224 that can be detachably arranged is further connected to the other end of the atomization air tube 23 and the other end of the start air tube 21 and the barrel portion 220, thereby avoiding a situation that the atomization air tube 23 and the start air tube 21 are connected to the shell 22 out of the field of view. In addition, since the connection operation is difficult, at least one of the first end portion 222 and second end portion 224 being detachably connected to the barrel portion 220 may effectively improve the convenience of connecting the atomization air tube 23 and the start air tube 21 to the shell 22, thereby reducing the difficulty of assembly and improving the efficiency of assembly.

[0044] In some embodiments, the first end portion 222 is arranged relatively close to the suction nozzle opening 101, and the first end portion 222 is detachably connected to the barrel portion 220. The second end portion 224 and the barrel portion 220 are integrally arranged. The first end portion 222 is made of a sealing material and further forms a seal structure together with the barrel portion 220 and the suction nozzle 10 to prevent liquid leakage.

[0045] The first end portion 222 is covered on the end of the barrel portion 220 facing toward the suction nozzle opening 101, and the end of the atomization air tube 23 close to the suction nozzle opening 101 and the end of the start air tube 21 close to the suction nozzle opening 101 are inserted into the first end portion 222 and is cooperated with the first end portion 222 in a sealed manner.

[0046] In some embodiments, the start air tube 21 is connected to the two ends of the shell 22 in an interference-fit manner, that is, the two ends of the start air tube 21 are respectively connected to the first end portion 222 and the second end portion 224 in an interference-fit manner, which makes the disassembly and assembly convenient and can also prevent liquid linkage at the joints between the start air tube 21 and the first end portion 222 and the second end portion 224.

[0047] In some embodiments, the start air tube 21 is connected to the two ends of the shell 22 in a screwed connection manner. The screwed connection manner also has the functions of making disassembly and assembly convenient and preventing liquid linkage.

[0048] The atomization air tube 23 may also be connected to the ends of the shell 22 in the same manner as the start air tube 21.

[0049] The inhalation channel 103 includes the tube of the atomization air tube 23, and the tube of the atomization air tube 23 may form a part of the inhalation channel 103, and may also form the whole of the inhalation channel 103. When the atomization core 30 is arranged in the inhalation channel 103, the atomization core 30 may be accommodated in the atomization air tube 23, or the atomization core 30 is at least partially accommodated in the atomization air tube 23, or the atomization core 30 may also be arranged outside the atomization air tube 23 provided that the inhalation channel 103 passes through the atomization core 30. The specific installation position and structure of the atomization core 30 are not specifically limited in the present disclosure.

[0050] In some embodiments, the atomization core 30 is accommodated in the atomization air tube 23, and a liquid inlet hole communicating with the liquid storage cavity 102 is defined in the atomization air. The atomization core 30 absorbs liquid from the liquid storage cavity 102 through the liquid inlet hole, and atomizes the liquid in the inhalation channel 103, in this way, the airflow in the inhalation channel 103 can take away the aerosol generated by the atomization in time during inhalation of a user.

[0051] Referring to FIG. 4, the transition opening 105 may be arranged on the second housing 14 and / or the first end portion 222. For example, the transition opening 105 is a hole structure on the second housing 14. In some embodiments, the transition opening 105 is a notch structure arranged on the second housing 14. The opening side of the notch structure is abutted against the first end portion 222, in this way, gas-liquid substances entering the cavity 13 due to various factors may pass through the notch structure after condensation to enter the atomization air tube 23, and may be absorbed and atomized by the atomization core 30. In some embodiments, the transition opening 105 is a groove structure arranged on the first end portion 222. One end of the groove structure is in communication with the cavity 13, and the other end of the groove structure is in communication with the suction nozzle opening 101 and the atomization air tube 23, which is conducive to guide liquid accumulated in the cavity 13 to the atomization air tube 23.

[0052] External water vapor or aerosol flowing through the inhalation channel 103 inevitably enters into the cavity 13. There is a risk that the gas-liquid substances enter the start air tube 21 after condensation in the cavity 13. Therefore, limiting the position of the transition opening 105 helps to discharge liquid in the cavity 13 in time, so as to lower the risk that the start air tube 21 fails due to liquid entering the start air tube 21.

[0053] Further, referring to FIG. 3 and FIG. 4, the port of the start air tube 21 close to the suction nozzle opening 101 is higher than the end surface of the shell 22 close to the suction nozzle opening 101, and the port of the start air tube 21 close to the suction nozzle opening 101 is higher than the end surface of the first end portion 222. Therefore, there is a height difference between the port of the end of the start air tube 21 close to the suction nozzle opening 101 and the end surface of the first end portion 222, in this way, when there is liquid (for example, condensate) accumulated on the end surface of the first end portion 222, the risk that liquid enters the start air tube 21 may be lowered, that is, the risk that the start air tube 21 fails due to liquid entering the start air tube 21 may be lowered.

[0054] The height difference H between the port of the start air tube 21 close to the suction nozzle opening 101 and the end surface of the shell 22 close to the suction nozzle opening 101 is greater than or equal to 0.1 mm, which may effectively lower the risk that the start air tube 21 fails due liquid entering the start air tube 21.

[0055] In some embodiments, the height difference H may be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 2.1 mm, or the like.

[0056] Further, referring to FIG. 4 and FIG. 5, FIG. 5 is a schematic exploded structural view of an elastic base and a liquid storage tank in the atomizer shown in FIG. 4.

[0057] The atomizer 100 further includes an elastic base 40, the elastic base 40 includes a first through-hole 401 and a second through-hole 402 spaced apart from each other. The elastic base 40 is connected to the end of the shell 22 away from the suction nozzle opening 101, the first through-hole 401 is in communication with the port of the atomization air tube 23 away from the suction nozzle opening 101, and the second through-hole 402 is in communication with the port of the start air tube 21 away from the suction nozzle opening 101. The end of the elastic base 40 away from the suction nozzle opening 101 is elastically abutted against the host 200 to space the first through-hole 401 and the second through-hole 402 apart from each other.

[0058] In case where the atomizer 100 is connected to the host 200, the elastic base 40 is abutted against the host 200, in this way, the end of the second through-hole 402 away from the start air tube 21 is in communication with the start switch 201. The end of the first through-hole 401 away from the atomization air tube 23 is in communication with the external atmosphere. The first through-hole 401 may be in communication with the external atmosphere through a holder on the host 200, or may directly be in communication with the external atmosphere directly through the opening of the housing in the host 200.

[0059] The elastic base 40 forms elastic seal by receiving the clamping forces from the both sides in case where the atomizer 100 is connected to the host 200, in this way, the first through-hole 401 is spaced apart from the second through-hole 402, thereby preventing damaging the start switch 201 from liquid leakage or the like in the inhalation channel 103.

[0060] Further, at least one isolation rib 403 is arranged at the end of the elastic base 40 away from the suction nozzle opening 101, and the isolation rib 403 is arranged around at least one of the first through-hole 401 or the second through-hole 402.

[0061] The number of the isolation rib 403 may be one, and the isolation ribs 403 may be arranged around the first through-hole 401 or the second through-hole 402. In some embodiments, the number of the isolation ribs 403 may be two. The two isolation ribs 403 are arranged around the first through-hole 401 and the second through-hole 402 respectively.

[0062] In case where the atomizer 100 is connected to the host 200, the isolation rib 403 protrudes from the end surface of the elastic base 40. Therefore, the effect that the elastic base 40 is hermetically abutted against the host 200 are better, in this way, the effect of spacing the first through-hole 401 and the second through-hole 402 from each other is better.

The accommodating portion 44 includes the second through-hole 402, and at least a part of the accommodating portion 44 is accommodated in the accommodating groove 226 and is hermetically arranged with the groove wall of the accommodating groove 226, so as to cover the accommodating groove 226. Further, the start air tube 21 is in communication with the second through-hole 402 through the accommodating groove 226.

[0067] Further, the port of the start air tube 21 facing toward the accommodating groove 226 and the port of the second through-hole 402 facing toward the accommodating groove 226 are arranged in a staggered manner, which may prevent liquid from falling directly into the second through-hole 402 when there is liquid in the start air tube 21. Therefore, the liquid may be collected in the accommodating groove 226, which helps to reduce the risk that the start switch 201 fails.

[0079] An electronic atomizing device is provided and includes a host and any one of the atomizer mentioned above. The host is connected to the atomizer, and the end of the start air tube away from the suction nozzle opening is in communication with the start switch on the host.

[0080] An atomizer is provided and includes a body including an inhalation channel in communication with the suction nozzle opening, and a start air tube arranged in the body.

[0082] Different from the related art, the present disclosure provides an atomizer and an electronic atomizing device. In the present disclosure, the independent start air tube passing through a liquid storage cavity of a shell is arranged to form a start airflow channel that is not shared with an inhalation channel, so as to prevent the problem that an atomizer cannot be started after the inhalation channel is blocked. In addition, the end of the start air tube close to the suction nozzle opening is in communication with the end of the inhalation channel close to the suction nozzle opening, that is, the start air tube is also in direct communication with the suction nozzle opening. Moreover, this position is located on the side of the liquid storage cavity close to the suction nozzle opening, and being close to the suction nozzle opening prevents this position from being easily blocked by aerosol condensate. Therefore, even when the inhalation channel is blocked, during inhalation, a user can still start the atomizer through the start air tube for heating. After the heating is started, an atomization core inside the inhalation channel heats up for atomization, which can reduce the viscosity of an atomizing substrate that blocks the inhalation channel to make the atomizing substrate flow away or atomized. Therefore, the bad situation that inhalation channel is blocked can be eliminated, and the atomizer can return to normal and continue to be used, thereby improving the reliability of the atomizer. In addition, compared with the existing solution that a liquid storage cavity, a inhalation channel, and a start airflow channel are directly formed on a housing of atomizer, the start air tube of the present disclosure is detachably arranged, that is, the start air tube can be independently manufactured as a separate component, in this way, the start air tube can be miniaturized, which can significantly reduce the manufacturing difficulty of other components in the atomizer and improve the yield rate of the atomizer. In addition, the miniaturized start air tube occupies less space in the liquid storage cavity, and has less impact on the capacity of the liquid storage cavity.

[0083] The foregoing descriptions are merely embodiments of the present disclosure, and the patent scope of the present disclosure is not limited thereto. All equivalent structure or process changes made according to the content of the present disclosure and accompanying drawings in the present disclosure or by directly or indirectly applying the present disclosure in other related technical fields shall fall within the protection scope of the present disclosure. 3
