Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomizers, in particular to an oil core separation structure of an electronic atomizer. Background Art

[0002] An electronic atomizer is a device that can heat the atomized oil without burning it to generate an aerosol.

[0003] Traditional electronic atomizers have the problem of the atomizer oil and the heating plate being in contact for too long, resulting in a poor taste or corrosion of the heating plate. In addition, due to the long-term contact between the atomizer oil and the atomizer core assembly, the atomizer oil is likely to leak out through the internal airway, resulting in a short service life. Currently, the atomizer oil and the atomizer core assembly are usually separated to solve the above problems. The current electronic atomizer core assembly is heated by electricity to atomize the atomizer oil to generate an aerosol. When the atomizer oil and the atomizer core assembly are only separated without turning off the circuit, the atomizer oil remaining in the atomizer core assembly can continue to atomize under the action of electricity, which can easily lead to misuse by others; and when the power is on for a long time, the separation of the atomizer oil and the atomizer core assembly can easily cause the atomizer core assembly to dry burn and be damaged. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, an electronic atomizer oil core separation structure is provided, which can realize the free switching of the oil core connection and separation while controlling whether the electronic atomizer is powered on, thereby achieving the technical effect of controlling the start and stop of the electronic atomizer.

[0005] The utility model provides the following technical solutions:

[0006] The utility model proposes an oil core separation structure of an electronic atomizer, comprising a shell, a suction nozzle, an air guide tube, an air guide tube outer cover, oil guide cotton and a heating sheet; the air guide tube outer cover is sleeved in the shell, and an oil storage chamber is formed between the shell and the air guide tube outer cover; the upper end of the air guide tube is sleeved in the suction nozzle, and the suction nozzle can move up and down relative to the air guide tube, and a locking device is further provided between the air guide tube and the suction nozzle; the remaining part of the air guide tube is sleeved in the air guide tube outer cover, and the upper end of the air guide tube outer cover is connected to the suction nozzle, and the air guide tube outer cover can move up and down with the suction nozzle; the oil guide The cotton is located at the lower end of the air guide pipe, and an oil inlet hole is provided between the oil-conducting cotton and the oil storage chamber; the heating plate is arranged in the oil-conducting cotton, and the positive lead and the negative lead of the heating plate extend to the bottom of the oil inlet hole; the air guide pipe outer cover is a conductor, and the air guide pipe outer cover can move downward to its lower end to close the oil inlet hole, and its lower end is connected to the positive lead and the negative lead to short-circuit the positive lead and the negative lead; the locking device can lock the suction nozzle when the suction nozzle drives the air guide pipe outer cover to move downward to close the oil inlet hole, so that the electronic atomizer maintains an unusable state with the oil core separated and the smoke cut off.

[0007] Furthermore, the locking device is a threaded device comprising a first thread disposed on the inside of the nozzle and a second thread disposed on the outside of the airway tube. The first and second threads cooperate to lock the nozzle. Using the threaded locking mechanism, the nozzle requires both up-and-down and rotational movement to unlock the electronic atomizer, providing a child-proof lock. This prevents conventional electronic atomizers from being opened by simply moving the nozzle up-and-down, thereby opening the oil inlet and causing the electronic atomizer to be unlocked, a problem that can easily lead to child misuse.

[0008] Furthermore, the distance between the first thread and the second thread is greater than or equal to the distance between the air duct cover and the bottom of the oil inlet; when the air duct cover moves downward until the oil inlet hole is closed, the suction nozzle and the vent pipe are locked by the first thread and the second thread; an automatic reset component is provided under the suction nozzle, and after the first thread and the second thread are unlocked, the automatic reset component can drive the suction nozzle and the air duct cover to move upward and reset, so that the oil inlet hole is opened.

[0009] Furthermore, the automatic reset component is a compression spring; the upper end of the compression spring is connected to the suction nozzle, and the lower end is connected to the air guide tube.

[0010] Furthermore, a sealing silica gel is provided at the bottom of the oil storage cavity, and when the air guide pipe outer cover seals the oil inlet hole, its lower end is connected to the sealing silica gel to achieve complete sealing.

[0011] Furthermore, a first sealing ring is provided on the top of the air storage chamber; a second sealing ring is provided between the air guide tube and the air guide tube outer cover, and the second sealing ring is provided at the bottom of the air guide tube.

[0012] Furthermore, the electronic atomizer oil core separation structure also includes two electrode nails, and the two electrode nails are respectively connected to the positive lead and the negative lead.

[0013] Furthermore, it also includes a core bracket and an air duct, the core bracket is arranged in the air duct; the oil-conducting cotton is arranged in the core bracket; the air duct is connected to the air guide pipe; and the oil inlet hole is arranged on the air duct.

[0014] Furthermore, the oil-guiding cotton, the heating sheet, the core bracket and the air duct constitute an atomizing core assembly. The atomizing core assembly is arranged at the lower end of the air duct.

[0015] Furthermore, the electronic atomizer oil core separation structure also includes a base, which is located at the lower end of the shell; the base is provided with a base bracket, and the air duct is installed on the base bracket; the base and the base bracket are provided with electrode holes, and the electrode nails are passed through the electrode holes and connected to the positive lead and the negative lead.

[0016] Furthermore, a through hole is provided on the top of the shell, and the suction nozzle is inserted into the through hole and can move up and down relative to the through hole; a limiting member is provided in the through hole, and the limiting member can limit the lower end of the suction nozzle in the shell.

[0017] The utility model has the following beneficial technical effects:

[0018] This utility model features a simple and reliable structure. As the nozzle drives the airway cover up and down, opening or closing the oil inlet, the lower end of the cover can be connected or disconnected from the positive and negative leads. This allows for free switching between oil wick engagement and separation while controlling the power supply to the atomizer core assembly, thereby controlling the start and stop of the electronic atomizer. Furthermore, a locking device controls whether the nozzle is locked, allowing the electronic atomizer to remain in a usable state (with the oil wick engaged and powered) or a non-usable state (with the oil wick separated and short-circuited).

[0033] Please refer to further Figure 2 In this embodiment, the locking device is a thread, which includes a first thread arranged on the inner side of the suction nozzle 2 and a second thread arranged on the outer side of the air guide tube 3. The first thread and the second thread can cooperate with each other to achieve locking of the suction nozzle 2.

[0034] Specifically, a sealing silica gel 8 is provided at the bottom of the oil storage cavity 5. When the air guide tube outer cover 4 seals the oil inlet hole 6, its lower end is connected to the sealing silica gel 8 to achieve complete sealing.

[0035] Specifically, a sealing ring fixing ring 13 is provided on the top of the air storage chamber, and a first sealing ring 14 is provided inside the sealing ring fixing ring 13. The first sealing ring 14 is tightly connected to the air duct outer cover 4; a second sealing ring 15 is provided between the air duct 3 and the air duct outer cover 4, and the second sealing ring 15 is arranged at the bottom of the air duct 3.

[0036] Specifically, two electrode nails 12 are further included, and the two electrode nails 12 are connected to the positive electrode lead 921 and the negative electrode lead 922 respectively.

[0037] Specifically, the atomizer further includes a core support 930 and an air duct 940. The core support 930 is disposed within the air duct 940.

A compression spring 7 is located below the nozzle 2, with its upper end connected to the nozzle 2 and its lower end connected to the air duct 3.

[0043] In this embodiment, when the electronic atomizer is not in use, the mouthpiece 2 can be pressed to move the airway cover 4 downward until the oil inlet 6 is closed. The mouthpiece 2 and the airway are locked together by the first and second threads 210, 310. Simultaneously, the bottom of the airway cover 4 contacts the positive lead 921 and the negative lead 922, achieving electrical conductivity, thereby separating the oil wick of the electronic atomizer and stopping the inhalation of smoke. When the electronic atomizer is ready for use, the mouthpiece 2 is rotated to unlock the first and second threads 210, 310. Once unlocked, the compression spring 7 drives the mouthpiece 2 and the airway cover 4 upward to reset, opening the oil inlet 6 and separating the airway cover 4 from the positive lead 921 and the negative lead 922. The electronic atomizer resumes its oil wick connection and power-on state.
