In an embodiment, the air guide channel includes a groove provided on the outer surface of the air guide element.
In an embodiment, the atomizer includes an electrical connection terminal electrically connected to a power supply mechanism, where a second insertion hole for the electrical connection terminal to be inserted is formed on the seal member, and an electrode lead of the heating element of the atomization assembly is bent and inserted into the second insertion hole to be electrically connected to the electrical connection terminal.

Further, the liquid storage member transfers the liquid substrate to the atomization assembly for heat and atomization, to generate the aerosol. In this way, the liquid substrate in the liquid storage cavity is not completely adsorbed on the liquid storage member, and the liquid substrate can still independently exist in the first portion in a liquid form. As a result, a space utilization rate of the liquid storage cavity can be effectively improved, and more liquid substrate can be accommodated in the liquid storage cavity.

FIG. 2 is a schematic three-dimensional view of the atomizer in FIG. 1 in a direction. FIG. 3 is a schematic cross-sectional view of the atomizer in FIG. 1 in a direction. FIG. 4 is a schematic cross-sectional view of the atomizer in FIG. 3 with a liquid storage member hidden.
This application provides an atomizer 100, which is configured to atomize a liquid substrate to generate an aerosol. As shown in FIG. 1 to FIG. 4, the atomizer 100 includes a housing 10 and a bottom base 20. The housing 10 has a first end 11 and a second end 12 that are opposite to each other along a length direction of the housing. A suction nozzle 111 for a user to inhale the aerosol is formed on the first end 11. The second end 12 is arranged to be open. At least part of the bottom base 20 extends into the housing 10 through an opening of the second end 12 to support a component in the housing 10.
A liquid storage cavity 13 is formed in the housing 10. The liquid storage cavity 13 is configured to store an atomizable liquid substrate. An air guide tube 14 longitudinally extends in the liquid storage cavity 13. The air guide tube 14 is in communication with the suction nozzle 111. The air guide tube 14 is configured to transmit an atomized aerosol, so as to transmit the aerosol to the suction nozzle 111 for the user to inhale.
The liquid storage cavity 13 is provided with a first liquid guide member 15 surrounding an inner wall of the housing 10. The first liquid guide member 15 divides the liquid storage cavity 13 into a first portion 131 and a second portion 132 that are longitudinally distributed. The first portion 131 is hollow to store the liquid substrate. The second portion 132 is filled with a liquid storage member 16. The first liquid guide member 15 is in contact with the liquid storage member 16, so that the first liquid guide member 15 is configured to absorb the liquid substrate in the first portion 131 and transfer the liquid substrate to the liquid storage member 16 for storage.
The first liquid guide member 15 and the liquid storage member 16 may include a flexible fiber such as a woolen fiber, a non-woven, or a glass fiber string, or include a cellular material having a micro-cellular structure, such as cellular ceramics, so that the first liquid guide member 15 and the liquid storage member 16 can absorb the liquid substrate and transfer the liquid substrate through a gap or a micro-cellular structure in the first liquid guide member and the liquid storage member.
FIG. 5 is a schematic exploded view of an atomization assembly of the atomizer in FIG. 3 from a perspective. FIG. 6 is a schematic exploded view of the atomizer in FIG. 3.
As shown in FIG. 5 and FIG. 6, a first through hole 161 longitudinally extending through is provided on the liquid storage member 16. An atomization assembly 17 is arranged in the first through hole 161. The atomization assembly 17 includes a second liquid guide member 171 and a heating element 172 that are incorporated on the second liquid guide member 171. Specifically, a second through hole 1711 longitudinally extending through is provided on the second liquid guide member 171, so that the second liquid guide member 171 has an outer surface 1712 and an inner surface 1713. The heating element 172 is incorporated on the inner surface 1713. The outer surface 1712 is in contact with the liquid storage member 16, to absorb a liquid substrate in the liquid storage member 16 and transfer the liquid substrate to the heating element 172 on the inner surface. The heating element 172 heats and atomizes the liquid substrate to generate an aerosol, and releases the aerosol in the second through hole 1711. In other words, the second through hole 1711 is an atomization chamber 1714 of the atomizer 100.
The second liquid guide member 171 may also be made of a flexible fiber such as a woolen fiber, a non-woven, or a glass fiber string, or may be made of a cellular material having a micro-cellular structure, such as cellular ceramics, so that the second liquid guide member 171 can absorb the liquid substrate from the liquid storage member 16 and transfer the liquid to the inner surface 1713, and transfer the liquid to the heating element 172 for heating and atomization. Correspondingly, the heating element 172 may be incorporated onto the second liquid guide member 171 or wound on the second liquid guide member 171 through printing, deposition, sintering, physical assembly, or the like.
As shown in FIG. 2, the bottom base 20 is provided with an air inlet 22 and an electrode hole. The air inlet 22 is configured to provide an airflow inlet for the external air to enter the atomizer 100. The electrode hole is provided with an electrical connection terminal 21. The electrical connection terminal 21 is electrically connected to an electrode lead 1721 of the heating element 172. A portion of the electrical connection terminal 21 is exposed to an end surface of the bottom base 20, so as to electrically connect to a power supply mechanism through an exposed portion, thereby enabling the power supply mechanism to supply electric energy to the heating element 172.
As shown in FIG. 4 and FIG. 6, a third through hole 151 is formed on the first liquid guide member 15. The air guide tube 14 extends through the third through hole 151 to the first through hole 161. Further, when the user inhales at the suction nozzle 111, negative pressure is generated inside the atomizer 100. External air enters the atomizer 100 through an air inlet 22, flows to the atomization chamber 1714, carries the aerosol generated in the atomization chamber 1714 to the air guide tube 14, and finally flows to the suction nozzle 111 through the air guide tube 14 for the user to inhale.
According to the atomizer 100 provided in the embodiments, the liquid storage cavity 13 is divided into the first portion 131 and the second portion 132 that are longitudinally distributed. Then, the liquid substrate in the first portion 131 is conducted to the liquid storage member 16 in the second portion 132 through the first liquid guide member 15 for storage. Further, the liquid storage member 16 transfers the liquid substrate to the atomization assembly 17 for heat and atomization, to generate the aerosol. In this way, the liquid substrate in the liquid storage cavity 13 is not completely adsorbed on the liquid storage member 16, and the liquid substrate can still independently exist in the first portion 131 in a liquid form. As a result, a space utilization rate of the liquid storage cavity 13 can be effectively improved, and more liquid substrate can be accommodated in the liquid storage cavity 13.
As shown in FIG. 4, in some embodiments, a length dimension of the first liquid guide member 15 in a transverse direction is greater than a length dimension in a longitudinal direction. However, a length dimension of the liquid storage member 16 in the longitudinal direction is greater than a length dimension in the transverse direction, so that the first liquid guide member 15 is a relatively thin thickness, and the liquid storage member 16 has a relatively thick thickness. The first liquid guide member 15 may rapidly transfer the liquid substrate to the liquid storage member 16, and more liquid substrate may also be stored in the liquid storage member 16. In addition, in some embodiments, a volume of the first portion 131 is greater than a volume of the second portion 132, so that more liquid substrate can be stored in the first portion 131, to increase a total liquid volume of the liquid storage cavity 13.
As shown in FIG. 3 and FIG. 6, in some embodiments, an accommodating member 30 is further arranged in the second portion 132, an accommodating chamber 31 is formed on the accommodating member 30, and the liquid storage member 16 is accommodated in the accommodating chamber 31. In some examples, the accommodating member 30 is non-transparent. When the housing 10 is designed to be transparent to cause a remaining liquid amount in the liquid storage cavity 13 to be observed through the housing 10, because a color of the liquid storage member 16 changes due to the infiltration of the liquid substrate, the accommodating member 30 can cover the liquid storage member 16 when the liquid storage member 16 is accommodated in the accommodating chamber 31, so as to avoid that the liquid storage member 16 is observed through the transparent housing 10, thereby avoiding visual discomfort caused to the user.
As shown in FIG. 3, in some embodiments, the accommodating member 30 has the first end and the second end arranged opposite to each other in a longitudinal direction. The first end and the second end are both arranged to be open. The first end supports the first liquid guide member 15, so that the first liquid guide member 15 may conduct the liquid substrate in the first portion 131 to the liquid storage member 16 through the opening of the first end 11. The opening of the second end is configured to cause the external air to enter the atomization chamber 1714. Although the liquid storage member 16 has a certain function of locking a liquid, the liquid substrate still seeps out of the liquid storage member 16 in a small amount with long-term use of the atomizer 100, and leaks through the opening of the second end. Therefore, to prevent the liquid substrate from leaking in this manner, the atomizer 100 is further provided with a seal member 40. The seal member 40 is at least partially located in the accommodating chamber 31, and is in interference fit with an inner wall of the accommodating chamber 31 to seal the accommodating chamber 31, thereby preventing the liquid substrate from leaking out of the accommodating chamber 31.
Further, in some embodiments, the bottom base 20 and the accommodating member 30 are fixedly connected. However, the liquid storage member 16 is positioned in the accommodating member 30, and the atomization assembly 17 is positioned in the liquid storage member 16. Therefore, the bottom base 20, the accommodating member 30, the liquid storage member 16, and the atomization assembly 17 may be combined into an independent assembly through the fixed connection between the bottom base 20 and the accommodating member 30. During assembly, the housing 10 is first inverted, then the first liquid guide member 15 is loaded into the housing 10, the independent assembly is loaded into the housing 10, and finally the bottom base 20 is pressed into the housing 10 to complete assembly, thereby effectively improving assembly efficiency. In addition, the bottom base 20, the accommodating member 30, the liquid storage member 16, and the atomization assembly 17 form an independent assembly, which may further help a customer of a manufacturer of the atomizer 100 inject the liquid substrate. After completing the injection, the customer directly loads the independent assembly into the housing 10.
FIG. 7 is another schematic exploded view of the atomizer in FIG. 3.
In a preferred implementation shown in FIG. 7, an insertion portion 23 extending longitudinally is formed on the bottom base 20, and a first insertion hole 41 adapted to the insertion portion 23 is formed on the seal member 40. The insertion portion 23 is inserted into the first insertion hole 41 and is in interference fit with a hole wall of the first insertion hole 41, so that the seal member 40 is in interference fit with the bottom base 20. However, the seal member 40 is also in interference fit with an inner wall of the accommodating member 30. Further, the bottom base 20 and the accommodating member 30 may be fixedly connected through the seal member 40, so that the bottom base 20, the accommodating member 30, the liquid storage member 16, and the atomization assembly 17 form an independent assembly.
In some embodiments, still referring to FIG. 3 and FIG. 7, a second insertion hole 42 is further formed on the seal member 40. The electrical connection terminal 21 is inserted into the second insertion hole 42. During assembly, an electrode lead 1721 of the heating element 172 may be bent and assembled into the second insertion hole 42, so that the electrode lead 1721 is electrically connected to the electrical connection terminal 21. Compared with that the electrode lead 1721 is bent and assembled into the electrode hole of the bottom base 20, because the bottom base 20 is a hard adhesive, the electrode lead 1721 to be assembled into the second insertion hole 42 that is of a soft adhesive is much more facilitated, thereby improving assembly efficiency.
Further, in some embodiments, as shown in FIG. 3 and FIG. 6, a first through hole 161 of the liquid storage member 16 has an air outlet port and an air inlet port arranged opposite to each other. The air outlet port is configured to cause the aerosol in the atomization chamber 1714 to escape from the liquid storage member 16, while the air inlet port is configured to cause the external air to enter the atomization chamber 1714. A tubular member 162 extends between the atomization chamber 1714 and the air outlet port. The air guide tube 14 partially extends into the tubular member 162, so that the aerosol in the atomization chamber 1714 can flow into the air guide tube 14 through the tubular member 162. The tubular member 162 is arranged to prevent the liquid substrate in the liquid storage member 16 above the atomization assembly 17 from seeping into the atomization chamber 1714, so that the liquid substrate can be prevented from seeping into the atomization chamber when the user inhales. Therefore, use experience of the user is affected.
Further, in some embodiments, as shown in FIG. 6, an air vent 1621 is formed on a tube wall of the tubular member 162. The external air may enter the liquid storage member 16 through the air vent 1621, and flow to the first portion 131 of the liquid storage cavity 13 through a gap or a micro hole in the liquid storage member 16, which effectively relieves the negative pressure generated in the first portion 131 and causes the liquid substrate in the first portion 131 to smoothly flow to the liquid storage member 16. In this way, the air vent 1621 is used as an air channel for guiding the external air to the liquid storage cavity 13.
In some embodiments, as shown in FIG. 3, an abutting boss 141 transversely extends on an outer wall of the air guide tube 14. The abutting boss 141 abuts against the first liquid guide member 15, and the abutting boss 141 applies a pressing force to the first liquid guide member 15, so that the first liquid guide member 15 is positioned in the liquid storage cavity 13.

An embodiment of this application further provides an atomizer 100a. As shown in FIG. 3, and FIG. 8 to FIG. 10, the atomizer 100a includes a housing 10a, a first liquid guide member 15a, a liquid storage member 16a, an accommodating member 30a, a seal member 40a, a bottom base 20a, and an atomization assembly 17a. The housing 10a, the first liquid guide member 15a, the liquid storage member 16a, and the atomization assembly 17a are all the same as the housing 10, the first liquid guide member 15, the liquid storage member 16, and the atomization assembly 17 in Embodiment I. An accommodating chamber 31a configured to accommodate the liquid storage member 16a is formed on the accommodating member 30a. The seal member 40a is in interference fit with an inner wall of the accommodating chamber 31a to seal the accommodating chamber 31a, to prevent a liquid substrate that seeps out of the liquid storage member 16a from leaking out of the accommodating chamber 31a.
In some embodiments, as shown in FIG. 8 to FIG. 10, an air guide element 32a longitudinally extending toward the liquid storage member 16a is formed on the accommodating member 30a. A through hole 41a for the air guide element 32a to pass through is formed on the seal member 40a. The air guide element 32a and an inner wall of the through hole 41a define an air channel. The air channel is configured to guide the external air to the liquid storage member 16a, and enter the first portion 131a of the liquid storage cavity through the liquid storage member 16a, to relieve negative pressure in the first portion 131a, thereby causing the liquid substrate in the first portion 131a to smoothly flow to the liquid storage member 16a.
Further, in some embodiments, as shown in FIG. 8 to FIG. 10, a groove 321a extending longitudinally is formed on an outer surface of the air guide element 32a. The foregoing air channel is defined by the groove 321a and an inner wall of the through hole 41a. Alternatively, in some embodiments, the groove 321a may also be formed through the inner wall of the through hole 41a, so that the air channel is defined by the groove 321a and an outer surface of the air guide element 32a.
In some embodiments, as shown in FIG. 8 to FIG. 10, the bottom base 20a is provided with an electrode hole, an electrical connection terminal 21a is inserted into the electrode hole, a gap 33a is defined between the accommodating member 30a and the bottom base 20a, and the electrode lead 1721 of the atomization assembly 17a is electrically connected to the electrical connection terminal 21a through the gap 33a, so that the electrical connection terminal 21a transmits the electric energy to the atomization assembly 17a.
In some embodiments, as shown in FIG. 4, and FIG. 8 to FIG. 10, an abutting boss 11a transversely extends on an inner wall of the housing 10a, and the abutting boss 11a abuts against the first liquid guide member 15a, thereby positioning the first liquid guide member 15a in the liquid storage cavity 13.
