[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a disposable electronic cigarette with adjustable pressure decompression. Background Technology

[0002] Currently, in existing disposable e-cigarettes, the power supply voltage to the cartridge is constant, resulting in a fixed heating temperature of the heating element inside the cartridge. Consequently, the amount of vapor produced by heating the e-liquid is limited. This limited vapor production cannot simultaneously meet the different vapor needs of various users. Furthermore, disposable e-cigarettes lack any movable or audible features to enhance their usability. Users cannot use them for entertainment during work or social activities, and they cannot relieve stress or anxiety. Utility Model Content

[0003] The purpose of this invention is to provide a disposable electronic cigarette with adjustable pressure and decompression. By designing a turntable, the adjustable pressure and ticking sound can be achieved through rotation. This solves the problems of existing disposable electronic cigarettes, such as the inability to adjust the pressure to change the amount of vapor, resulting in the vapor production not meeting the needs of different users, and the low playability, which prevents them from relieving stress and anxiety for users.

[0004] The technical solution adopted by this utility model to solve the technical problem is: a disposable electronic cigarette with adjustable pressure and decompression, including a main body and a turntable rotatably mounted on the main body. The main body is provided with a cartridge for storing and atomizing e-liquid, and a power supply component for supplying power to the cartridge. The power supply component includes a telescopic structure corresponding to the inner wall of the turntable and a voltage regulator. The inner wall of the turntable is provided with a connecting rod connected to the voltage regulator and a plurality of protrusions arranged in sequence and evenly. The telescopic structure has a telescopic contact that abuts against the inner wall of the turntable. The telescopic contact is located on the rotation trajectory of each of the protrusions and the turntable.

[0005] In one embodiment, the voltage regulator is provided with a voltage regulating knob, and the voltage regulating knob has a connecting groove. The connecting rod is connected to the voltage regulator by being inserted into the connecting groove. Both the connecting rod and the connecting groove are square.

[0006] In one embodiment, the turntable is circular, and the outer wall of the turntable is provided with a plurality of grooves for increasing friction, and each of the grooves is arranged evenly in sequence on the outer wall of the turntable.

[0007] In one embodiment, the power supply assembly further includes a power board and a battery cell, the battery cell being electrically connected to the power board, the telescopic structure and the voltage regulator being disposed on the power board, and the voltage regulator being electrically connected to the power board.

[0008] In one embodiment, the telescopic structure includes a housing and a cover, as well as a spring. The housing is fixed to the power board, and the telescopic contact and the spring are disposed inside the housing. A support rod is attached to the telescopic contact, and the lower end of the spring is sleeved on the support rod. The upper end of the spring abuts against the inner wall of the housing. The cover is fastened to the housing, and an opening is provided at the bottom end of the cover. Under the elastic force of the spring, the telescopic contact extends out from the opening and abuts against the inner wall of the turntable.

[0009] In one embodiment, the main body includes a shell, the battery cell and the power board, and the cartridge are all disposed inside the shell. The power board is electrically connected to the cartridge. The outer wall of the shell has a circular hole corresponding to the power board. One end of the turntable is inserted into the shell through the circular hole and covers the power board, so that the telescopic structure and the voltage regulator correspond to the inner wall of the turntable, and the telescopic contact abuts against the inner wall of the turntable. The other end of the turntable is exposed outside the shell.

[0010] In one implementation, the power supply voltage range of the power board to the cartridge is 3.3V to 5.5V, and the voltage regulator can also adjust the voltage range of 3.3V to 5.5V.

[0011] In one embodiment, the outer diameter of the turntable is smaller than the diameter of the circular hole, and one end of the turntable protrudes outward along the edge to form a convex edge, which abuts against the inner wall of the outer shell.

[0012] In one embodiment, the cartridge contains an oil storage chamber, which contains a mist tube. A mist channel is formed within the mist tube, with its upper end extending to the top of the cartridge and its lower end extending to the bottom of the cartridge. A heating element electrically connected to the power board is located within the mist channel. The heating element's electrical connection to the power board constitutes an electrical connection between the cartridge and the power board. An oil inlet corresponding to the heating element is formed on the outer wall of the mist tube, and a through hole corresponding to the top of the cartridge is formed on the top of the outer shell.

[0013] In one embodiment, the main body also includes a mouthpiece, the lower end of which is inserted into the outer shell through the through hole, and the bottom end of the mouthpiece abuts against the top of the cartridge.

[0023] The following detailed description of the embodiments of this utility model, in conjunction with the accompanying drawings, will provide a thorough understanding of how this utility model uses technical means to solve technical problems and achieve technical effects, enabling its implementation. It should be noted that, provided there is no conflict, the various embodiments and features within them can be combined with each other, and all resulting technical solutions are within the protection scope of this utility model.

[0024] It should be noted that the specification of this application contains a large number of technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described utility model content, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, one example discloses feature A+B+C, and another example discloses feature A+B+D+E. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; they cannot be used simultaneously. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described.

[0025] like Figure 1-7 As shown, this utility model provides a disposable electronic cigarette with adjustable pressure and decompression, including a main body 10 and a turntable 11 rotatably mounted on the main body 10. The main body 10 is provided with a cartridge 3 for storing and atomizing e-liquid, and a power supply assembly 1001 for supplying power to the cartridge 3. The power supply assembly 1001 includes a telescopic structure 1002 corresponding to the inner wall of the turntable 11 and a voltage regulator 501. The inner wall of the turntable 11 is provided with a connecting rod 1103 connected to the voltage regulator 501, and a plurality of protrusions 1104 arranged in sequence and evenly. The telescopic structure 1002 has a telescopic contact 8 that abuts against the inner wall of the turntable 11. The telescopic contact 8 is located on the rotation trajectory of each protrusion 1104 rotating with the turntable 11. It should be noted that by designing a turntable 11 on the main body 10, the turntable 11 adjusts the power supply voltage to the cartridge 3 by rotating the power supply component 1001 on the main body 10, so that the cartridge 3 atomizes to produce different amounts of smoke to meet the needs of different users. This not only realizes the adjustable voltage of disposable electronic cigarettes, but also produces a ticking sound when the user rotates the turntable 11 and the telescopic contact 8 collides with the protrusion 1104, which can relieve the user's stress and anxiety.

[0026] In some embodiments, the voltage regulator 501 is provided with a voltage regulating knob 502, and the voltage regulating knob 502 has a connecting groove 503. The connecting rod 1103 is connected to the voltage regulator 501 by inserting into the connecting groove 503. Both the connecting rod 1103 and the connecting groove 503 are square. It should be noted that when the turntable 11 rotates clockwise on the main body 10, the connecting rod 1103 can drive the voltage regulating knob 502 to rotate clockwise, thereby increasing the power supply voltage of the power supply component 1001 to the tobacco cartridge 3. When the turntable 11 rotates counterclockwise on the main body 10, the connecting rod 1103 can drive the voltage regulating knob 502 to rotate counterclockwise, thereby decreasing the power supply voltage of the power supply component 1001 to the tobacco cartridge 3. The fact that both the connecting rod 1103 and the connecting groove 503 are square prevents the connecting rod 1103 from slipping when driving the voltage regulating knob 502 to rotate within the connecting groove 503.

[0027] In some embodiments, the turntable 11 is circular, and its outer wall is provided with a plurality of grooves 1101 for increasing friction. Each groove 1101 is arranged evenly in sequence on the outer wall of the turntable 11. The grooves 1101 are used to increase the friction between the surface of the turntable 11 and the fingers to prevent slippage when rotating the turntable 11. The grooves 1101, the connecting rod 1103, and the protrusions 1104 are integrally formed with the turntable 11, without the need for machining or assembly.

[0028] In some embodiments, the power supply assembly 1001 further includes a power board 5 and a battery cell 4. The battery cell 4 is electrically connected to the power board 5. A telescopic structure 1002 and a voltage regulator 501 are disposed on the power board 5, and the voltage regulator 501 is electrically connected to the power board 5. The battery cell 4 supplies power to the power board 5 to enable its electronic control function. The power board 5 supplies power to the voltage regulator 501, so that when the connecting rod 1103 drives the voltage regulating knob 502 to rotate, the supply voltage from the power board 5 to the cartridge 3 can be changed.

[0029] In some embodiments, the telescopic structure 1002 includes a housing 6 and a cover 9, and a spring 7. The housing 6 is fixed on the power board 5. The telescopic contact 8 and the spring 7 are disposed inside the housing 6. The telescopic contact 8 is supported by a support rod 801. The lower end of the spring 7 is sleeved on the support rod 801. The upper end of the spring 7 abuts against the inner wall of the housing 6. The cover 9 is fastened to the housing 6. The bottom end of the cover 9 has an opening 901. The telescopic contact 8 extends out from the opening 901 under the elastic force of the spring 7 and abuts against the inner wall of the turntable 11. The housing 6 is used to house the spring 7 and the telescopic contact 8. The cover 9 is used to seal the spring 7 and the telescopic contact 8 inside the housing 6. The support rod 801 is used to connect and support the lower end of the spring 7. When the turntable 11 rotates, each protrusion 1104 also rotates with the turntable 11. After being resisted by each protrusion 1104, the telescopic contact 8 can retract into the housing 6 through the opening 901, causing the spring 7 to deform and generate elastic force. Under the action of the elastic force of the spring 7, the telescopic contact 8 can be ejected and collide with each protrusion 1104 to produce a ticking sound, thereby relieving the user's stress and anxiety.

[0030] In some embodiments, the main body 10 includes a housing 2, a battery cell 4, a power board 5, and a cartridge 3, all housed within the housing 2. The power board 5 is electrically connected to the cartridge 3. A circular hole 201 corresponding to the power board 5 is provided on the outer wall of the housing 2. One end of the turntable 11 is inserted into the housing 2 through the circular hole 201 and covers the power board 5, such that the telescopic structure 1002 and the voltage regulator 501 correspond to the inner wall of the turntable 11, and the telescopic contact 8 abuts against the inner wall of the turntable 11. The other end of the turntable 11 is exposed outside the housing 2. The housing 2 is used to house the battery cell 4, the power board 5, and the cartridge 3. The power board 5 also supplies power to the cartridge 3 to atomize the e-liquid and produce vapor. The circular hole 201 allows one end of the turntable 11 to be inserted into the housing 2 and covered by the power board 5, while the other end of the turntable 11 is exposed outside the housing 2, facilitating rotation by the user outside the housing 2.

[0031] In some embodiments, the power supply voltage range from 3.3V to 5.5V supplied by the power board 5 to the cartridge 3 is 3.3V to 5.5V, and the adjustable voltage range of the voltage regulator 501 is also 3.3V to 5.5V. Specifically, the power supply voltage range from the power board 5 to the cartridge 3, and the adjustable voltage range of the voltage regulator 501, are 3.3V, 3.6V, 3.9V, 4.2V, 4.5V, 4.8V, 5.1V, and 5.5V. These voltage levels and ranges allow the cartridge 3 to properly atomize e-liquid and produce vapor, and each level results in a significantly different amount of vapor produced by the cartridge 3.

[0032] In some embodiments, the outer diameter of the turntable 11 is smaller than the diameter of the circular hole 201. One end of the turntable 11 protrudes outward along its edge to form a raised edge 1102, which abuts against the inner wall of the outer casing 2. The smaller outer diameter of the turntable 11 allows it to rotate outside the outer casing 2 smoothly. The abutment between the raised edge 1102 and the inner wall of the outer casing 2 prevents the turntable 11 from being pulled out of the outer casing 2 through the circular hole 201 during rotation.

[0033] In some embodiments, the cartridge 3 is provided with an oil storage chamber 302, an atomizing tube 303 is provided in the oil storage chamber 302, an atomizing channel 301 is formed in the atomizing tube 303, the upper end of the atomizing channel 301 extends to the top of the cartridge 3, the lower end of the atomizing channel 301 extends to the bottom of the cartridge 3, a heating core 304 electrically connected to the power board 5 is provided in the atomizing channel 301, the heating core 304 is electrically connected to the power board 5, the cartridge 3 is electrically connected to the power board 5 by the electrical connection, the outer wall of the atomizing tube 303 is provided with an oil inlet hole 305 corresponding to the heating core 304, and the top of the outer shell 2 is provided with a through hole 202 corresponding to the top of the cartridge 3. The oil storage chamber 302 is used to store e-liquid, the mist tube 303 is used to isolate the e-liquid in the oil storage chamber 302, the mist channel 301 is used for airflow and smoke exhaust, the heating core 304 is used to heat up the e-liquid in the oil storage chamber 302 after being powered by the power board 5, and then heats the e-liquid in the oil storage chamber 302 to produce smoke, the oil inlet 305 is used to guide the e-liquid in the oil storage chamber 302 into the heating core 304, and the through hole 202 is used to allow the mouthpiece 1 to be inserted into the outer shell 2.

[0034] In some embodiments, the main body 10 further includes a mouthpiece 1, the lower end of which is inserted into the outer shell 2 through the through hole 202, and the bottom end of the mouthpiece 1 abuts against the top end of the e-liquid cartridge 3. A smoking channel 101 corresponding to and communicating with the upper end of the mist channel 301 is provided inside the mouthpiece 1. The mouthpiece 1 is used to hold the mouth in the mouth to smoke, and the smoking channel 101 is used to draw the smoke generated by the heating element 304 heating the e-liquid in the mist channel 301 into the mouth.

The upper end of the mist channel 301 extends to the top of the cartridge 3, and the lower end of the mist channel 301 extends to the bottom of the cartridge 3. A heating element 304 is provided in the mist channel 301 for heating the e-liquid in the oil storage chamber 302 to produce smoke. An opening is formed on the outer wall of the mist tube 303 to connect with the heating element 304. The corresponding oil inlet 305 is used to guide the e-liquid in the oil storage chamber 302 into the heating core 304. The top of the outer shell 2 has a through hole 202 corresponding to the top of the cartridge 3. The lower end of the mouthpiece 1 is inserted into the outer shell 2 through the through hole 202, and the bottom end of the mouthpiece 1 abuts against the top of the cartridge 3. The upper end of the mouthpiece 1 is exposed at the top of the outer shell 2 for inhaling smoke. The mouthpiece 1 has a smoke channel 101 corresponding to and communicating with the upper end of the mist channel 301, used to draw the smoke generated by the heating core 304 heating the e-liquid into the mouth.

The power board 5 is also electrically connected to the heating element 304 to supply power and heat the e-liquid. A voltage regulator 501 is provided on the power board 5 to adjust the supply voltage to the heating element 304. The voltage regulator 501 contains a voltage adjustment knob 502 for adjusting the supply voltage to the heating element 304 by rotation. The voltage adjustment knob 502 has a connecting groove 503 for connecting the turntable 11. The cover 6 is fixed to the power board 5 to accommodate the spring 7 and the telescopic contact 8. The telescopic contact 8 and the spring... 7 is located inside the housing 6. The support rod 801 on the telescopic contact 8 is used to connect and support the lower end of the spring 7. The lower end of the spring 7 is sleeved on the support rod 801, and the upper end of the spring 7 abuts against the inner wall of the housing 6. The cover 9 is fastened inside the housing 6 to seal the spring 7 and the telescopic contact 8 inside the housing 6.
