Description

Technical Field

[0001] The present invention relates to the technical field of aerosol generators, and in particular to an aerosol generator. Background Art

[0002] Existing aerosol generators mainly include two parts: an atomizing device and a power supply device. The atomizing device absorbs the oil stored in the oil storage chamber through the atomizing core configured inside it, and then heats and atomizes the oil in the atomizing chamber to produce an aerosol, which finally flows out of the device through the suction port. The power supply device is used to provide power to the atomizing device. The atomizing chamber and the air inlet channel of the existing atomizing device are usually straight-through structures from top to bottom, which causes the oil absorbed into the atomizing chamber by the atomizing core or the condensate formed by cooling in the atomizing chamber to flow directly into the air inlet channel under the action of gravity, and then seep out of the device or flow into the power supply device, which is easy to corrode the components in the power supply device.

[0033] Please refer to Figure 1-6 , which is a schematic diagram of a preferred embodiment of the aerosol generator provided by the present invention. The aerosol generator includes an atomizing device 1 and a power supply device 2 provided with an air inlet channel 21, and the atomizing device 1 includes a shell 11, an atomizing component 12 having an atomizing channel 15, and a base 13 electrically connected to the atomizing component 12. The shell 11 covers the base 13 to enclose an oil storage chamber 14, the atomizing component 12 is accommodated in the oil storage chamber 14, and the atomizing channel 15 passes through the oil storage chamber 14 to form an air passage independent of the oil storage chamber 14. The base 13 is provided with a blind hole 16, the open end 161 of the blind hole 16 extends into the shell 11 and is connected to the atomizing channel 15, the closed end 162 of the blind hole 16 extends to the outside of the shell 11, and the side wall of the closed end 162 is provided with a first air inlet hole 163 respectively connected to the open end 161 and the outside air. When the atomizing device 1 is detachably mounted on the power supply device 2, the base 13 is electrically connected to the power supply device 2, so that the atomizing assembly 12 is electrically connected to the power supply device 2. At the same time, the first air inlet hole 163 is connected to the air inlet channel 21, so that the outside air can enter the first air inlet hole 163 through the air inlet channel 21. In this embodiment, a blind hole 16 connected to the channel is provided on the base 13 of the atomizing device 1, and a first air inlet hole 163 is provided on the side wall of the blind hole 16, so that air is taken in through the air inlet channel 21 in the power supply device 2. In this way, the oil or condensate in the atomizing channel 15 can be prevented from directly flowing into the power supply device 2, and at the same time, an air inlet port is avoided on the surface of the atomizing device 1, which is conducive to maintaining the integrity of the device.

[0034] In this embodiment, if Figure 1-2 As shown, the shell 11 is a hollow tubular structure, which can be made of plastic, metal or glass. Preferably, the shell 11 is made of transparent or translucent material, which is convenient for users to check the remaining oil in the oil storage chamber 14. The base 13 is installed at one end of the shell 11 and closes the opening at one end of the shell 11. The base 13 includes a first electrode seat 131, a first insulating member 133 and a first electrode column 132. The first electrode seat 131 is a columnar structure, which is provided with a first mounting hole along the axial direction, and the outer side wall of the first mounting hole is folded outward to form a support ring. The opening at one end of the shell 11 is sleeved on the outer periphery of the first electrode seat 131, and the end face of the open end 161 is in contact with the support ring to achieve positioning and support. In practical applications, the shell 11 and the first electrode seat 131 can be fixedly connected by interference fit or threaded connection.

[0035] Further, the first insulating member 133 is sleeved on the first electrode column 132 and passes through the first mounting hole. The first insulating member 133 is made of an elastic electrically insulating material, and elastically abuts against the outer periphery of the first electrode column 132 and the inner wall of the first mounting hole, respectively, so as to fix the first electrode column 132 to the first electrode seat 131. Preferably, the first electrode seat 131 passes through the first mounting hole, and one end extends into the shell 11, and the other end is exposed outside the shell 11. In practical applications, the blind hole 16 can be provided in the first electrode seat 131, or in the first insulating member 133, or in the first electrode column 132. It can also be provided between the first electrode seat 131 and the first insulating member 133, or between the first insulating member 133 and the first electrode column 132.

[0036] In this embodiment, if Figure 1As shown, the atomization assembly 12 includes an atomization tube, a heating element and an oil guide element. The atomization tube is installed in the shell 11 along the axial direction of the shell 11, and an annular oil storage chamber 14 is formed between the outer wall of the atomization tube and the inner wall of the shell 11. The heating element and the oil guide element are installed in the atomization tube, and form an atomization channel 15 independent of the oil storage chamber 14 with the channel in the atomization tube. In practical applications, the heating element can be wound around the oil guide element, and the oil guide element vertically penetrates the atomization tube, and both ends extend into the oil storage chamber 14 to absorb the oil in the oil storage chamber 14. The heating element can also be coaxially embedded in the oil guide element, and the oil guide element is coaxially inserted into the atomization tube, and absorbs the smoke oil in the oil storage chamber 14 through the oil hole on the side wall of the atomization tube. One end of the heating element is electrically connected to the first electrode column 132, and the other end is electrically connected to the first electrode seat 131, and is electrically connected to the power supply device 2 through the base 13 to obtain power.

[0037] Furthermore, the atomizer tube can be integrally formed with the housing 11, or can be installed in the housing 11 through a fastener or a seal. Preferably, one end of the atomizer tube passes through the first seal and is connected to the suction port of the housing 11, and the other end passes through the second seal 18 and is connected to the blind hole 16, and is fastened in the housing 11 through the elastic contact between the first seal and the second seal 18 and the inner wall of the housing 11.

[0038] Since the base 13 is provided with a first air inlet hole 163 and a blind hole 16 for air intake, the atomizing tube is connected to the blind hole 16 to obtain the air required for atomization. In practical applications, one end of the atomizing tube may directly form a sealed connection with the open end 161 of the blind hole 16, or may not establish a connection relationship with the open end 161 of the blind hole 16. Preferably, a liquid storage chamber 17 is also provided between the atomizing tube and the open end 161 of the blind hole 16. The blind hole 16 end of the atomizing tube is connected through the liquid storage chamber 17. The liquid storage chamber 17 is used to store the oil or condensate flowing out of the atomizing channel 15 to prevent the liquid flowing out of the atomizing tube from directly flowing into the open end 161 of the blind hole 16, and then seeping out of the atomizing device 1 and entering the power supply device 2.

[0039] Further, if Figure 6As shown, the second seal 18 is located between the atomizing tube and the open end 161 of the blind hole 16, and the second seal 18 is provided with a third mounting hole for mounting the atomizing tube. One end of the third mounting hole is connected to the atomizing tube to fasten the atomizing tube and communicate with the atomizing tube. For example, one end of the atomizing tube can be sleeved on the outer periphery of the third mounting hole, or can extend into the third mounting hole. The other end of the third mounting hole is connected to the open end 161 of the blind hole 16, and the open end 161 of the blind hole 16 can be flush with the end face of the third mounting hole, or can extend slightly into the third mounting hole to ensure smooth flow of airflow. In this way, the space between the second seal 18 and the base 13 encloses the oil storage chamber 14, and the oil in the atomizing tube flows into the third mounting hole under the action of gravity, and then flows into the liquid storage chamber 17 from the third mounting hole, thereby reducing the probability of oil infiltrating into the air intake channel 21.

[0040] Preferably, the end of the third mounting hole communicating with the blind hole 16 is tapered, and its inner diameter gradually increases in the direction close to the base 13, and the maximum inner diameter of the third mounting hole is larger than the inner diameter of the opening end 161 of the blind hole 16. In this way, the inner wall of one end of the third mounting hole is an outwardly expanding inclined surface, and the oil flowing into the third mounting hole from the atomizing pipe flows along the inner wall of the third mounting hole and then along the inclined surface into the liquid storage chamber 17, thereby reducing the probability of the oil flowing into the blind hole 16.

[0041] Furthermore, the liquid storage chamber 17 is also filled with an oil absorbing member, which can be made of porous materials, such as oil-absorbing cotton, foam or porous ceramics. The oil absorbing member further absorbs the oil accumulated in the liquid storage chamber 17, thereby improving the liquid storage capacity of the liquid storage chamber 17, thereby effectively preventing the oil from flowing or seeping out of the liquid storage chamber 17.

[0042] In this embodiment, if Figure 3As shown, the blind hole 16 is provided on the first electrode column 132. The first electrode column 132 includes a first column 1321 and a second column 1322, and the first column 1321 and the second column 1322 are coaxially connected. The open end 161 of the blind hole 16 passes through the first column 1321 and extends to the second column 1322, and forms a closed end 162 with the end wall of the second column 1322 away from the first column 1321. The first air inlet 163 is provided on the side wall of the second column 1322 and is connected to the open end 161. By providing the first air inlet 163 on the side wall of the blind hole 16, air intake at the bottom side of the atomizing device 1 is realized, and condensate is prevented from flowing directly into the power supply device 2 along the air inlet channel 21. The first air inlet 163 can be one, two or more. Preferably, there are four first air inlet holes 163, and the four first air inlet holes 163 are evenly distributed along the circumference of the second column 1322 to achieve uniform air intake.

[0043] Preferably, the outer diameter of the second column 1322 is greater than the outer diameter of the first column 1321, so that the depth of the first air inlet 163 can be increased, so that when the oil flows from the atomization channel 15 into the blind hole 16, the speed of oil leakage can be slowed down to prevent the oil from directly flowing into the power supply device 2. In addition, since the end surface of the second column 1322 facing away from the first column 1321 is exposed outside the housing 11 for electrical connection to the atomization device 1, the contact area can be increased, thereby forming a more stable electrical contact.

[0044] Furthermore, a groove 1311 is provided at one end of the first electrode holder 131 exposed outside the housing 11, and a fourth mounting hole connected to the first mounting hole is provided on the bottom wall of the groove 1311. That is, one end of the first electrode column 132 and the first insulating member 133 extending outside the housing 11 through the first mounting hole is accommodated in the groove 1311, and there is a gap between the first electrode column 132 and the inner wall of the groove 1311. The gap reserves an air intake space for the first air intake hole 163 to prevent the first air intake hole 163 from being blocked.

[0045] In this embodiment, if Figure 1 and Figure 4 As shown, the power supply device 2 is provided with a mounting groove 24 for mounting the atomizing device 1. The bottom wall of the mounting groove 24 is provided with an air vent 212, and the housing 22 of the power supply device 2 is provided with a second air inlet hole 211 connected with the air vent 212 to form the air inlet channel 21. The atomizing device 1 is detachably mounted in the mounting groove 24, and the air vent 212 is connected with the first air hole 163 to connect the air inlet channel 21 with the atomizing channel 15.

[0046] In one embodiment of the present invention, Figure 1 , Figure 5 As shown, the power supply device 2 includes a housing 22, a bracket 23, a power supply assembly 29, a second electrode column 25, a second insulating member 26 and a second electrode seat 27. The bracket 23 is installed in the housing 22 and forms a mounting groove 24 for mounting the atomization device 1 and a mounting cavity for mounting the power supply assembly 29 with the housing 22. The bracket 23 is provided with a second mounting hole connecting the mounting groove 24 and the mounting cavity. The second insulating member 26 is sleeved on the second electrode column 25. The second electrode seat 27 is sleeved on the second insulating member 26 and forms the vent 212 with the second insulating member 26. Preferably, at least one vent groove 261 is provided on the outer periphery of the second insulating member 26 along the axial direction, and the inner side wall of the second electrode seat 27 and the vent groove 261 form the vent 212. In this way, the purpose of isolating the second electrode seat 27 and the second electrode column 25 by the second insulating member 26 is not affected, and the second insulating member 26 is conveniently processed by injection molding. Of course, the ventilation groove 261 can also be provided on the inner side wall of the second electrode holder 27, and the outer side wall of the second insulating member 26 and the ventilation groove 261 form the ventilation hole 212. It is worth noting that the ventilation groove 261 can also be provided on the second electrode holder 27, the second insulating member 26 or the second electrode column 25, which is not limited here.

[0047] The second electrode holder 27 is installed in the second mounting hole, and blocks the second mounting hole with the second insulating member 26 and the second electrode column 25 contained therein to form the bottom wall of the mounting groove 24. One end of the second electrode holder 27 is exposed in the mounting groove 24 for contact with the first electrode holder 131, and the other end extends into the mounting cavity. The second electrode holder 27 can be fixed by interference fit with the second mounting hole. In practical applications, the second electrode holder 27 is in the shape of a hollow cylinder, and the side wall of one end thereof extending into the mounting cavity is folded outward to form a circular ring, and fits with the end wall of the second mounting hole located in the mounting cavity to provide support and be used for welding wires. When the atomizer 1 is installed in the installation groove 24, the second electrode column 25 elastically abuts against the first electrode column 132, the second electrode seat 27 abuts against the first electrode seat 131, and the air vent 212 is connected with the first air inlet hole 163 to connect the air inlet channel 21 and the atomizer channel 15, so as to electrically connect the atomizer 1 with the power supply device 2.

[0048] In one embodiment of the present invention, the second electrode holder 27 is made of a magnetic conductive material. When the atomizer 1 is installed in the mounting groove 24, the second electrode holder 27 abuts against the first electrode holder 131, and while establishing an electrical connection, a magnetic connection is also formed to detachably connect the atomizer 1 to the power supply device 2. In practical applications, the thickness of the second electrode holder 27 can be adjusted according to the required magnetic force to increase or decrease the contact area between it and the first electrode holder 131. In this embodiment, the second electrode holder 27 is used to simultaneously realize the magnetic connection and the electrical connection, without the need to add a connection structure, thereby saving installation procedures and production costs.

[0049] In one embodiment of the present invention, the power supply device 2 further includes a magnetic collar 28, which is sleeved on the second insulating member 26 and accommodated in the second electrode seat 27. That is, the collar 28 is clamped between the second insulating member 26 and the second electrode seat 27. When the atomizer 1 is installed in the mounting groove 24, the first electrode seat 131 abuts against the second electrode seat 27 and the collar 28 at the same time to achieve magnetic connection and electrical connection. In this embodiment, the magnetic connection between the atomizer 1 and the power supply device 2 is achieved by setting a magnetic collar 28, which is quick to install and easy to disassemble. Of course, in practical applications, other connection methods can also be used, such as interference fit between the atomizer 1 and the side wall of the mounting groove 24, and friction is used to achieve detachable connection; a protrusion or buckle can also be set on the periphery of the atomizer 1, and a concave edge or a card slot can be set on the side wall of the corresponding position of the mounting groove 24 to achieve detachable connection.

[0050] In this embodiment, the power supply assembly 29 includes a battery element 291, a pneumatic switch 292 and a sealing seat 293. The sealing seat 293 is sleeved on the pneumatic switch 292 and fastened in the mounting cavity, and the outer periphery of the sealing seat 293 elastically abuts against the inner wall of the mounting cavity to separate the sealed cavity into two spaces. The battery element 291 is installed in the first space and is electrically connected to the pneumatic switch 292. The second air inlet 211 is arranged on the cavity wall of the second space. When the user inhales the atomizing device 1, after the outside air enters from the second air inlet 211, it can only flow into the space where the battery element 291 is installed through the pneumatic switch 292, and then flow into the vent 212 from the gap between the battery element 291 and the inner wall of the mounting cavity. In this way, the suction resistance can be increased and a sense of holding breath can be provided.

[0051] Furthermore, an air-replenishing hole 2931 may be provided in the sealing seat 293, and the air-replenishing hole 2931 is used to connect the first space and the second space. Therefore, the air entering the second space can enter the first space through the air-replenishing hole 2931 in addition to entering the first space through the pneumatic switch 292. The air-replenishing hole 2931 is used to replenish air for the pneumatic switch 292, so as to prevent the air flow around the pneumatic switch 292 from being unsmooth, resulting in insensitive triggering, and at the same time, the suction resistance can be reduced to a certain extent. In practical applications, the aperture of the air-replenishing hole 2931 can be adjusted according to the actual trigger sensitivity requirements and suction resistance requirements.

[0052] In this example, the power supply assembly 29 also includes components such as a control board and a USB interface installed in the second space. Since the first space and the second space are separated by a sealing seat 293, the liquid flowing into the first space from the vent 212 will not enter the second space, thereby protecting the control board. Preferably, the second air inlet 211 is adapted to the USB interface, and the USB interface is installed in the second air inlet 211. In this way, the holes for air intake and plugging in the USB interface are combined into one, and only one hole needs to be opened in the power supply device 2, so that the outer surface of the entire aerosol generator only needs to open a suction port and a second air inlet 211, which maximizes the integrity of the appearance of the equipment and reduces the number of hole opening stations, which is conducive to improving production efficiency.
