Description

Technical Field

[0001] The utility model relates to a detachable aerosol device which is easy to plug and unplug. Background Art

[0002] The aerosol device generates an aerosol by arranging a heating element in the oil storage chamber to heat and atomize the oil. The atomization device can obtain power by being integrally connected to the power supply device or detachably connected. When an integral connection is adopted, the pins led out from the heating element can be directly welded to the battery element of the power supply device to obtain power. When a detachable connection is adopted, the pins led out from the heating element are electrically connected to the contact piece, and then the power is obtained by electrically contacting the power supply device through the contact piece. The existing contact piece usually adopts two conductive posts. During installation, the two conductive posts need to be pressed into the mounting holes on the base of the electronic atomization device respectively, and at the same time, the pins in the mounting holes need to be pressed tightly. This not only increases the installation process, but also has the risk of the conductive posts falling off. On the other hand, the end faces of the two conductive posts form an area that can be contacted with power, and there is a problem of small contact area.

[0034] Please refer to Figure 1-5The utility model proposes a detachable aerosol device that is easy to plug and unplug, comprising a shell 1, a base 2, an atomizer assembly 4 and a contact assembly 3. The shell 1 is provided with a suction port 12 at one end and an opening 11 at the other end. The base 2 closes the opening 11 and forms an oil storage chamber 5 with the shell 1. The atomizer assembly 4 has a first lead and a second lead (not shown in the figure), and one end of the atomizer assembly 4 is connected to the suction port 12, and the other end is plugged into the base 2 to form an atomization channel 6 that passes through the oil storage chamber 5. The contact assembly 3 includes a PCB board 31, a first contact column 33 and two second contact columns 32. The PCB board 31 is fastened to the base 2, and one side is electrically connected to the first lead and the second lead respectively, the first contact column 33 and the two second contact columns 32 are plugged into the other side of the PCB board 31 at intervals and exposed outside the shell 1, and the first contact column 33 is electrically connected to the first lead via the PCB board 31, and the two second contact columns 32 are electrically connected to the second lead via the PCB board 31. The utility model adopts the PCB board 31 as an adapter board to connect the lead wire and the conductive contact column of the atomizer assembly 4, which not only makes the electrical connection between the two more reliable, but also makes the installation position of the conductive contact column more flexible, thereby facilitating the forward and reverse direction plugging of the aerosol device.

[0035] In some embodiments, Figure 1 and Figure 2 As shown, the atomization assembly 4 may include a heating element, an oil guide element, and a sleeve. The heating element is a hollow cylindrical structure formed by winding a heating wire or a heating net, and has a first through hole along the axial direction of the shell 1. The first lead and the second lead are respectively led out from the two ends of the heating element, and are electrically connected to an external power source through the first lead and the second lead to obtain power. The oil guide element is sleeved on the periphery of the heating element, and it can be made of oil-conducting cotton and / or porous ceramic material, and it can be separately connected to the heating element or integrally formed. The sleeve is sleeved on the periphery of the oil guide element to provide protection and support. One end of the sleeve is fastened and inserted into the base 2, and the other end is connected to the suction port 12, so that an atomization channel 6 independent of the oil storage chamber 5 is formed in the oil storage chamber 5, and the heating element and the oil guide element are both located in the atomization channel 6. Correspondingly, the sleeve is provided with an oil guide hole connecting the atomization channel 6 and the oil storage chamber 5, and the oil guide member is exposed from the oil guide hole to the oil storage chamber 5, so that the oil in the oil storage chamber 5 can be absorbed by the oil guide member through the oil guide hole, so as to be heated by the heating element and atomized into an aerosol, and finally flow out of the atomization device through the atomization channel 6 and the suction port 12.

[0036] In some embodiments, please refer to Figure 2-4The base 2 includes a seal 21 and a bottom cover 22, which are installed in the housing 1 from the opening 11 of the housing 1 in sequence. The outer periphery of the seal 21 elastically abuts against the inner wall of the housing 1 to seal the oil storage chamber 5 and prevent the liquid in the oil storage chamber 5 from flowing out from the opening 11. Further, the outer periphery of the seal 21 is provided with an annular receiving groove 214, and a sealing ring 7 is partially accommodated in the annular receiving groove 214. When the seal 21 is installed in the housing 1, the sealing ring 7 elastically abuts against the inner wall of the housing 1 and the annular receiving groove 214 respectively to increase the force between the seal 21 and the housing 1, thereby improving the sealing performance. The seal 21 is provided with a plug hole 212 adapted to the atomizer assembly 4, one end of the atomizer assembly 4 is inserted into the plug hole 212, and the outer periphery of the atomizer assembly 4 elastically abuts against the inner wall of the plug hole 212 to prevent oil from leaking from the gap between the two. In this embodiment, the atomization channel 6 is connected to the plug hole 212, and the outside air enters the atomization channel 6 through the plug hole 212 to participate in atomization. Correspondingly, the bottom cover 22 is provided with at least one air inlet hole 224, and the air inlet hole 224 is respectively connected to the outside air and the plug hole 212. When the user inhales from the suction port 12, the outside air enters the atomization channel 6 through the air inlet hole 224 and the plug hole 212 in sequence.

[0037] In some embodiments, Figure 4 As shown, the bottom cover 22 has at least one connecting column 223 protruding from one side toward the sealing member 21, and the sealing member 21 is correspondingly provided with at least one connecting hole 213. When the bottom cover 22 is installed in the shell 1, the connecting column 223 is inserted into the connecting hole 213, which can not only position the bottom cover 22, but also form a fastening connection between the bottom cover 22 and the sealing member 21. Further, a plurality of buckles 225 are protruding from the outer periphery of the bottom cover 22, and a plurality of matching slots 13 are provided at one end of the shell 1 close to the opening 11. The plurality of buckles 225 are snapped into the corresponding slots 13 to fix the base 2 to the shell 1, thereby preventing the base 2 from falling out of the shell 1. Preferably, the buckles 225 are distributed on both sides of the base 2, so that the two sides of the base 2 are respectively snapped into the shell 1, making the connection structure more stable.

[0038] In some embodiments, a mounting groove 221 for mounting the PCB board 31 is provided on one side of the bottom cover 22 facing the sealing member 21, the opening 11 of the mounting groove 221 faces the sealing member 21, and the PCB board 31 is accommodated in the mounting groove 221. In practical applications, the periphery of the PCB board 31 can be interference-fitted with the side wall of the mounting groove 221 to achieve fixation. In order to make the installation of the PCB board 31 more stable, the sealing member 21 is provided with at least one positioning column 211 protruding toward the bottom cover 22. The positioning column 211 includes a small diameter section 2111 away from the sealing member 21 and a large diameter section 2112 connected to the sealing member 21. Correspondingly, the PCB board 31 is provided with at least one positioning hole 315 adapted to the small diameter section 2111. The length of the small diameter section 2111 is less than or equal to the depth of the positioning hole 315. When the seal 21 is covered on the bottom cover 22, the small diameter section 2111 is inserted into the positioning hole 315. Since the outer diameter of the large diameter section 2112 is larger than that of the small diameter section 2111, the large diameter section 2112 protrudes in the circumferential direction and the end surface of the outer periphery of the small diameter section 2111 abuts against the PCB board 31. The displacement of the PCB board 31 in the axial direction is limited by the cooperation of the positioning column 211 and the positioning hole 315. In practical applications, the positioning column 211 can be one, two or more. The number and position of the positioning column 211 can be set according to the shape of the PCB board 31. For example, when the PCB board 31 is a rectangular plate, the positioning column 211 can be 4, and the corresponding positioning holes 315 are also 4. The 4 positioning holes 315 are respectively located near the four vertex corners of the PCB board 31, so that the PCB board 31 is evenly stressed in all directions.

[0039] In some embodiments, Figure 2 and Figure 5 As shown, the first lead and the second lead drawn from the atomizer assembly 4 are drawn from the plug hole 212 to between the seal 21 and the bottom cover 22 for electrical connection to the PCB board 31. The PCB board 31 is provided with a first welding portion 312 and a second welding portion 313 at intervals on one side of the atomizer assembly 4. The first welding portion 312 is used for welding with the first lead, and the second welding portion 313 is used for welding with the second lead. In practical applications, the first lead and the second lead can be directly welded to the corresponding welding portion using solder to achieve electrical connection between the two leads and the PCB board 31. Preferably, the first welding portion 312 and the second welding portion 313 are provided with a second welding hole 314. By extending the first lead and the second lead into the corresponding second welding hole 314, and then filling the second welding hole 314 with solder, the first lead and the second lead are fastened to the corresponding second welding hole 314, and a stable electrical connection is achieved with the PCB board 31. This not only reduces the difficulty of installation, but also the lead is not easy to come out of the PCB board 31, and the installation is more secure.

[0040] In some embodiments, Figure 2 As shown, the two second contact pins 32 are arranged symmetrically with respect to the first contact pin 33. In this way, when the atomizer device is turned 180 degrees, the two second contact pins 32 are swapped. That is, if one of the second contact pins 32 is in the initial position, it can be electrically contacted with the external power supply; when the atomizer device is turned 180 degrees, the two second contact pins 32 swap positions, and the other second contact pin 32 is in the initial position, and it can still be electrically contacted with the external power supply. In this way, the atomizer device can obtain power in both forward and reverse directions, which is convenient for users to operate.

[0041] In some embodiments, please refer to Figure 1 and Figure 2 , the first contact column 33 and the second contact column 32 have the same structure, both including a plug-in section 321 and a contact section 322. The plug-in section 321 is used to be fixedly connected and electrically connected to the PCB board 31. The contact section 322 is used to electrically contact with an external power supply. The outer diameter of the plug-in section 321 is smaller than the outer diameter of the contact section 322. Correspondingly, the PCB board 31 is provided with a first welding hole 311 adapted to the plug-in section 321. When the plug-in section 321 is inserted into the first welding hole 311, one end of the contact section 322 abuts against the side of the PCB board 31 away from the atomization component 4, and the other end passes through the base 2 and is exposed to the outside of the housing 1 for electrical connection to an external power supply. Correspondingly, the bottom wall of the mounting groove 221 is provided with a mounting hole 222 adapted to the contact section 322, and the contact sections 322 of the first contact column 33 and the second contact column 32 respectively pass through the corresponding mounting holes 222 and are exposed to the outside of the housing 1. Since the end surface of one end of the contact segment 322 abuts against the PCB board 31, when the end of the contact segment 322 exposed outside the housing 1 is in electrical contact with the external power source and is subjected to pressure, the contact segment 322 does not undergo axial displacement under the action of the PCB board 31, thereby facilitating a stable electrical connection with the external power source and preventing poor contact. It is worth noting that the structures of the first contact column 33 and the second contact column 32 may also be different, and the size and shape may be changed according to actual needs.

[0042] In some embodiments, the contact assembly 3 further includes an insulating member 34, which is circumferentially covered on the outer circumference of the contact segment 322 to prevent a short circuit between the first contact column 33 and the second contact column 32. In practical applications, the insulating member 34 is clamped between the PCB board 31 and the bottom wall of the mounting slot 221, and the insulating member 34 is provided with three avoidance holes 341 at intervals corresponding to the contact segments 322 of the first contact column 33 and the second contact column 32, and the contact segments 322 of each contact column respectively pass through the corresponding avoidance holes 341 and the mounting hole 222 in sequence to be exposed outside the housing 1.

[0043] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
