Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization devices. Background Art

[0002] Pre-filled electronic atomizers generally have the function of separating the oil core to ensure that there will be no oil leakage during transportation. However, the oil core separation function of most products of this type is achieved through a one-time structure, that is, the atomizer core does not have the function of resetting after being connected to the oil storage tank. Regardless of whether it is in the process of inhalation, the atomizer core and the oil storage tank are always connected, resulting in a higher probability of oil leakage from the atomizer core. Therefore, there is room for improvement in existing electronic atomizer devices of this type. Utility Model Content

[0025] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0028] See attached Figure 1-6 , shown is an electronic atomization device capable of controlling the oil core separation, the electronic atomization device 1 comprises a host 2 and a smoke cartridge 3, the host 2 comprises a main shell 200 and an electric control component 201 installed in the main shell 200, the electric control component 201 generally comprises a main board, a battery, etc., the smoke cartridge 3 is inserted into the main shell 200, the smoke cartridge 3 comprises a shell body, an oil storage bin 300 is formed in the shell body, an atomization core 301, an oil blocking device 301 are installed in the oil storage bin 300, The oil shield 302 is provided with an oil hole 303 connected with the oil storage bin 300, the atomizer core 301 is movably installed in the oil shield 302, and the atomizer core 301 is provided with an oil inlet hole 304 for the smoke oil to flow in; a drive control component is installed in the electronic atomization device 1, and the drive control component controls the movement of the atomizer core 301 compared with the oil shield 302 to adjust the opening and closing of the oil hole 303 and the oil inlet hole 304.

[0029] The atomizer core 301 of the common electronic atomization device 1 will be provided with more than one oil inlet hole 304, and the oil inlet hole 304 is used to keep the oil storage tank 300 in a continuous state of communication with the atomizer core 301. In this embodiment, an oil shield 302 is provided in the smoke bomb 3, and the oil shield 302 is in a straight cylindrical shape. The atomizer core 301 is movably installed in the oil shield 302, and the drive control component controls the movement of the atomizer core 301 relative to the oil shield 302, so as to adjust the mismatch of the oil through hole 303 and the oil inlet hole 304. When the two are staggered, the oil inlet hole 304 is closed, and the smoke oil cannot flow into the atomizer core 301 through the oil through hole 303 and the oil inlet hole 304. When the two are correspondingly merged, the oil inlet hole 304 is opened, and the smoke oil flows into the atomizer core 301 through the oil through hole 303 and the oil inlet hole 304. Therefore, according to actual use requirements, the user can separate the oil core at any time through the drive control component to reduce the risk of smoke oil leakage.

[0030] The atomizer core 301 can be controlled to separate the oil core by rotating. For example, the atomizer core 301 is driven by the motor structure to rotate in the oil shield 302. After a certain angle of forward rotation, the oil inlet hole 304 and the oil through hole 303 are completely misaligned, so that the oil inlet hole 304 is closed. After the corresponding angle of rotation is reset, the oil inlet hole 304 corresponds to the oil through hole 303, so that the oil inlet hole 304 is opened.

[0031] In some embodiments, the atomizer core 301 is slidably installed in the oil shield 302, and the drive control component controls the atomizer core 301 to move upward to connect the oil through hole 303 and the oil inlet hole 304, and the drive control component controls the atomizer core 301 to move downward to disconnect the oil through hole 303 and the oil inlet hole 304. The up and down movement of the atomizer core 301 can be controlled in a variety of ways, such as using a motor and a cam to pull the atomizer core 301 to move up and down in the oil shield 302.

[0032] In some embodiments, the drive control assembly includes a push-pull part 4 and a reset part 5, the push-pull part 4 is installed on the main unit 2, the reset part 5 is installed on the cigarette cartridge 3, and is connected to the atomizer core 301; when the push-pull part 4 is operated to move upward, the atomizer core 301 moves upward due to the thrust of the push-pull part 4; when the push-pull part 4 is operated to move downward, the reset part 5 resets the atomizer core 301 downward, and the push-pull part 4 can be locked at the end of the upward and downward strokes.

[0033] Push the push-pull part 4 upward, the push-pull part 4 drives the atomizer core 301 to move upward synchronously, the oil inlet hole 304 is connected with the oil through hole 303, and the push-pull part 4 is pulled downward, the atomizer core 301 is reset downward under the action of the reset member 5, and the oil inlet hole 304 is staggered with the oil through hole 303. The reset member 5 can be a compression spring, one end of the compression spring abuts against the atomizer core 301, and the other end can abut against the shell body of the cigarette cartridge 3, for example, abutting in the smoke outlet channel of the shell body. When the push-pull part 4 pushes the atomizer core 301 upward, the compression spring is forced to shrink. After the push-pull part 4 moves downward, the force on the compression spring disappears, and it stretches and resets and pushes the atomizer core 301 downward.

[0034] In some embodiments, a push-pull cavity 203 is provided in the main shell 200, an opening is provided at the upper portion of the push-pull cavity 203, a push-pull groove is provided at one side of the push-pull cavity 203, the push-pull portion 4 includes a push head 401 and a push rod 400, the push head 401 is installed in the push-pull cavity 203, and corresponds to the bottom of the atomization core 301 through the opening, one end of the push rod 400 is connected to the push head 401, and the other end extends out of the main shell 200 through the push-pull groove.

[0035] There are many ways to set the push-pull cavity 203, for example, the push-pull cavity 203 is integrally formed on the upper part of the main shell 200, or the bracket 202 is installed in the main shell 200 and a cavity structure is constructed in the bracket 202, or see the attached Figure 6 The push-pull chamber 203 is an independent component and can be fixed on the bracket 202 by means of tight fitting, snap fastening, etc. The upper part of the push-pull chamber 203 has an opening. The push rod 400 applies force to the push head 401, and the push head 401 applies an upward force to the atomizer core 301 through the opening. When descending, the push head 401 withdraws into the push-pull chamber 203 through the opening to make room for the downward reset of the atomizer core 301.

[0036] When the push-pull part 4 moves upward to the end of the stroke, it means that the atomizer core 301 is connected to the oil storage tank 300, and when it moves downward to the end of the stroke, it means that the atomizer core 301 is disconnected from the oil storage tank 300. In daily use, both states need to remain stable for a certain period of time. Therefore, the push-pull part 4 can be locked at the end of the upward and downward strokes. The locking method can be achieved by setting the push head 401 or the push rod 400.

[0037] In some embodiments, the push head 401 is provided with a transverse plug-in cavity, and a cavity opening is provided at one end of the plug-in cavity. The push rod 400 is inserted into the plug-in cavity via the cavity opening. An elastic member 402 is installed in the plug-in cavity, and the elastic member 402 generates an elastic external thrust on the push rod 400. The push rod 400 is provided with a limiting baffle 404; a radially protruding limiting portion 403 is provided on the push rod 400, and limiting holes 205 are provided at the upper and lower parts of the push-pull groove. At the end of the upward and downward stroke of the push rod 400, the elastic member 402 and the limiting baffle 404 cooperate to lock the limiting portion 403 in the limiting hole 205; the push rod 400 is pressed to disengage the limiting portion 403 from the limiting hole 205, so that the push rod 400 can move along the push-pull groove.

[0038] A part of the push rod 400 protrudes radially to form a thicker limiting portion 403. The limiting holes 205 at the upper and lower ends of the push-pull groove are adapted to the limiting portion 403, and the push-pull groove portion between the two limiting holes 205 is narrower. The push rod 400 is pressed to make its thinner part move up and down along the push-pull groove. At the end of the stroke, the push rod 400 will be pushed outward under the action of the elastic member 402. At the same time, due to the obstruction of the limiting baffle 404, the limiting portion 403 just falls into the limiting hole 205 and is locked. When it is necessary to switch the on-off state of the oil core, the push rod 400 is pressed to retract it into the plug-in cavity, and the limiting portion 403 is disengaged from the limiting hole 205. The thinner position of the push rod 400 corresponds to the push-pull groove, so that it can go up or down along the push-pull groove. After reaching the corresponding end of the stroke, the pressing force on the push rod 400 is cancelled, the elastic member 402 pushes the push rod 400, and the limiting portion 403 falls into the limiting hole 205 again and is locked.

[0039] The elastic member 402 can be a compression spring, one end of which abuts against the inner bottom surface of the insertion cavity, and the other end abuts against the limit portion 403 of the push rod 400. The limit baffle 404 can be arranged on the bracket 202, abutting against the outer side of the limit portion 403 to complete the restriction of the push rod 400.

[0040] In some embodiments, a smoke outlet channel is formed at the upper portion of the shell body, and a sealing seat 306 and a base 307 are installed at the lower portion of the shell body from top to bottom; the upper end of the oil shield 302 is installed in the smoke outlet channel, and the lower end of the oil shield 302 is installed on the sealing seat 306. When the atomizer core 301 moves downward, its lower end passes through the sealing seat 306 and reaches the base 307. A limiting cover 308 for accommodating the atomizer core 301 is provided on the base 307. The limiting cover 308 is provided with a limiting flange 309 to limit the downward stroke of the atomizer core 301. The limiting cover 308 is provided with a through hole so that the push head 401 pushes the atomizer core 301 through the through hole.

[0041] A through hole is provided on the sealing seat 306 at a position corresponding to the smoke outlet channel, and a supporting flange extending inward is provided at the bottom of the through hole. The upper end of the oil shield 302 is tightly inserted in the smoke outlet channel, and its lower end is inserted in the through hole and abuts against the supporting flange. The atomizer core 301 is installed in the oil shield 302. When going down, its lower end passes through the through hole and reaches the limit cover 308 on the base 307. The limit flange 309 on the limit cover 308 forms a blocking limit for the atomizer core 301. At the same time, the limit cover 308 is provided with a through hole, and the push head 401 applies an upward thrust to the atomizer core 301 through the through hole when going up.

[0042] In some embodiments, the aperture of the lower portion of the smoke outlet channel is larger than that of the upper portion, and a step portion 310 is formed between the two; the oil shield 302 is tightly inserted in the lower portion of the smoke outlet channel and abuts against the step portion 310, and the upper end of the atomizer core 301 is tightly inserted in the upper portion of the smoke outlet channel when the atomizer core 301 moves upward, and the atomizer core 301 and the smoke outlet channel are both provided with matching groove rail structures.

[0043] The upper end of the oil shield 302 is inserted into the lower part of the smoke outlet channel, and the stability of its installation is enhanced by abutting against the step portion 310 to prevent the atomizer core 301 from synchronously shifting when it moves up and down. When the atomizer core 301 moves upward, it is closely matched with the upper part of the thinner smoke outlet channel, and the two are closely connected, which is conducive to all the smoke flowing to the mouthpiece through the smoke outlet channel. There are many ways to set the groove and rail structure between the atomizer core 301 and the smoke outlet channel. For example, a longitudinal slide groove is set on the atomizer core 301, and a longitudinal slide rail is set on the smoke outlet channel. The two cooperate to enhance the stability of the up and down movement of the atomizer core 301.

[0044] In some embodiments, the limiting cover 308 is connected to the base 307 in a detachable manner, for example, by means of threads, snaps or tight fit, and the atomizer core 301 can be replaced after the limiting cover 308 is removed.

[0045] In some embodiments, the atomizer core 301 has a heating wire, and a base 305 is provided at the bottom of the atomizer core 301, and an atomizer electrode electrically connected to the heating wire is installed on the base 305; a host electrode 204 connected to the electric control component 201 is installed on the pusher head 401, and the host electrode 204 and the atomizer electrode are connected to each other at least when the pusher head 401 pushes the atomizer core 301 upward. Further, when the atomizer core 301 is reset downward, there is a gap between the atomizer electrode and the host electrode 204.

[0046] When the push head 401 pushes the atomizer core 301 upward synchronously, the host electrode 204 and the atomizer electrode are in contact with each other. After the push head 401 moves downward, the atomizer core 301 is reset. There is a gap between the push head 401 and the base 305, so that the host electrode 204 and the atomizer electrode are out of contact, thereby disconnecting the circuit between the cigarette cartridge 3 and the host 2 to avoid accidental startup.

[0047] In addition, in order to avoid the movement of the atomizer core 301 affecting the stability of the assembly of the cartridge 3 and the host 2, a matching snap-fit ​​structure can be provided on the cartridge 3 and the host 2. For example, when the cartridge 3 is inserted into the main shell 200 of the host 2, the two have some concave-convex structures to enhance the stability of the snap-fit, or a snap-fit ​​convex is provided on the cartridge 3, and an L-shaped slot is provided on the main shell 200. When the cartridge 3 is inserted downward into the main shell 200, the snap-fit ​​convex enters the L-shaped slot, and then the cartridge 3 is rotated so that the snap-fit ​​convex enters the lateral part of the L-shaped slot, thereby avoiding the up and down movement of the atomizer core 301 causing the cartridge 3 to separate from the host 2.

[0048] In summary, the improved electronic atomization device 1 can switch the connection between the atomization core 301 and the oil storage tank 300 through the drive control component, which is convenient for the user to flexibly select the oil core separation state according to the actual use environment, and effectively reduce the risk of oil leakage through the atomization core 301.
