Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a sliding self-locking electronic cigarette structure. Background Technology

[0002] Electronic cigarettes are a tobacco substitute that works by atomizing and heating e-liquid to create vapor for inhalation. Compared to traditional tobacco products, they eliminate the combustion process, reducing the production of harmful substances, environmental pollution, and fire risk. Depending on whether the cartridge is replaceable, electronic cigarettes are divided into integrated and replaceable types. Replaceable electronic cigarettes use a separate cartridge and battery design, with the cartridge being an independent consumable that can be replaced at any time, thus reducing the cost of using electronic cigarettes. Most detachable e-cigarettes on the market currently use magnetic or snap-fit ​​connections to connect the battery and cartridge. Magnetic connections are mainly used to lock the cartridge and battery in place, but their strength is often insufficient, leading to the battery detaching from the cartridge and damaging the e-cigarette. Snap-fit ​​e-cigarettes use a protrusion at the bottom of the cartridge and a slot at the top of the battery to accommodate it. The connection between the cartridge and battery is achieved through the interlocking of the slot and protrusion. However, this requires forceful insertion and removal, and with repeated cartridge replacements, the inner wall of the slot and the protrusion wear down, causing the connection between the battery and cartridge to loosen. This results in poor contact between the battery and cartridge, affecting the normal use of the e-cigarette. Utility Model Content

The locking component includes a protrusion fixed in the slide groove and a locking block elastically disposed in the guide groove in a second direction and corresponding to the protrusion. A locking groove is formed between the locking block and the limiting end. When the boss abuts against the limiting block, the elastic pin docks with the connecting terminal to electrically connect the cartridge and the battery rod. The protrusion is located in the locking groove and abuts against the locking block.

[0005] In one embodiment, the cross-section of the groove is T-shaped, or the inner wall of the groove is provided with at least one limiting protrusion, and the cross-sectional shape of the protrusion is adapted to the cross-sectional shape of the groove.

[0006] In one embodiment, the protrusion has a first slope on the side adjacent to the first connector, and a second slope on the side of the protrusion facing away from the first connector, the slope of the second slope being greater than the slope of the first slope.

[0007] In one embodiment, the edge of the cartridge shell is provided with a guide slope near the first insertion interface. The guide slope is provided with a wedge-shaped guide block corresponding to the guide groove. The side of the wedge-shaped guide block adjacent to the battery rod shell is flush with the bottom surface of the groove. A clearance groove is provided on the end face of the protrusion away from the elastic pin. The clearance groove corresponds to the second insertion interface.

[0008] In one embodiment, the cartridge includes a mouthpiece fixed to the top of the cartridge shell and communicating with the inner cavity of the cartridge shell, an oil tank disposed in the inner cavity of the cartridge shell for holding e-liquid, an atomizing core disposed in the inner cavity of the cartridge shell and communicating with the oil tank for heating and atomizing the e-liquid, and a first PCB board disposed in the inner cavity of the cartridge shell and electrically connected to the atomizing core. The bottom or side of the cartridge shell has an air inlet communicating with the atomizing core, the top of the atomizing core is communicating with the mouthpiece, and the top of the mouthpiece has a suction port communicating with the external environment.

[0009] In one embodiment, the connecting terminal includes a first end inserted into the shell of the cartridge and a second end facing away from the first end; the cartridge also includes at least one first spring piece soldered to the first PCB board and corresponding to each connecting terminal, the middle of the first spring piece is bent and the two ends of the first spring piece are arranged opposite to each other, and a snap-fit ​​area with adjustable width is formed between the two ends of the first spring piece for the first end to be inserted.

[0010] In one embodiment, the side of the second end facing away from the first end is flush with the bottom surface of the groove.

[0011] In one embodiment, the battery rod includes a partition, a battery, a second spring, and a second PCB board housed within a housing of the battery rod.

The second spring is housed within the elastic adjustment area and is fixedly connected to the partition. A guide groove is provided on the side of the battery rod housing facing away from the battery compartment, and a through hole communicating with the elastic adjustment area is provided in the guide groove. The locking block is fixedly connected to the elastic part of the second spring and passes through the through hole.

[0012] In one embodiment, the second spring has an M-shaped structure, the elastic part is formed in the middle of the second spring, and the locking screw is installed on the elastic part, or the locking block is integrally formed with the elastic part.

[0013] In one embodiment, a display screen electrically connected to the second PCB board is provided on a side of the battery rod housing that is opposite to the side where the boss is located.

[0014] The sliding self-locking electronic cigarette structure of this invention features a groove on the cartridge shell and a boss on the battery rod shell. The groove and boss mutually constrain each other, limiting the movement of the cartridge and battery rod in multiple directions. A protrusion is placed within the groove, and a guide groove is formed on the boss with a resilient locking block. When the battery rod is pushed towards the cartridge, the protrusion engages with the groove and resists the locking block, locking the cartridge and battery rod and preventing the cartridge from detaching from the battery rod. When the battery rod is pulled away from the cartridge, the protrusion compresses the locking block. The movement of the locking block and the clearance of the protrusion releases the lock between the cartridge and the battery rod, allowing the battery rod to be pulled out of the cartridge's groove. The disassembly and assembly are simple. After assembly, the mutual constraint between the protrusion and the locking block improves the stability of the connection between the cartridge and the battery rod. The elastic design of the locking block allows it to move under pressure, which helps reduce wear caused by the relative movement of the protrusion and the locking block during disassembly and assembly. The reliable connection between the cartridge and the battery rod avoids the problem of loose electrical connections and ensures the normal use of the e-cigarette. Attached Figure Description

[0024] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] Please combine Figure 1-4 as well as Figure 7This utility model discloses a stable, low-wear sliding self-locking electronic cigarette structure. The structure includes a cartridge 100, a battery rod 200 located outside the cartridge 100 and slidingly engaged with it, and a locking component connecting the cartridge 100 and the battery rod 200. Depending on the product form, the battery rod 200 can be positioned below or beside the cartridge 100. The locking component is located at the junction of the cartridge 100 and the battery rod 200 to lock and unlock them during sliding engagement. A groove 120 is provided on one side of the cartridge shell 110, extending along a first direction and penetrating one end of the cartridge shell 110 to form a first insertion interface 121. This first insertion interface 121 provides an insertion port for the battery rod 200 to be inserted into the groove 120. At least one connecting terminal 130 is provided within the slide groove 120. A limiting block 122 is fixed within the slide groove 120 away from the first insertion interface 121. The limiting block 122 is used to limit the depth to which the battery rod 200 is inserted into the slide groove 120 in the first direction, so that after the sliding self-locking electronic cigarette structure is assembled, the corresponding part on the cartridge 100 can be perfectly aligned with the corresponding part on the battery rod 200. The outer shell 210 of the battery rod is provided with a boss 220 that slides into the slide groove 120 and engages with the inner wall of the slide groove 120 in the second direction. The first direction is perpendicular to the second direction. In this embodiment, the two opposite sidewalls of the slide groove 120 also jointly restrict the movement of the boss 220 in a third direction, and this third direction is perpendicular to the first direction and the second direction, respectively. Thus, through the cooperation of the slide groove 120 and the boss 220, the cartridge 100 and the battery rod 200 can be limited in the planes of the second direction and the third direction, and the cartridge 100 and the battery rod 200 can also be limited in one direction in the first direction. The boss 220 is provided with at least one elastic pin 230 corresponding to each connecting terminal 130. The elastic pin 230 is elastically disposed on the outer shell 210 of the battery rod along the second direction, and when naturally extended, the elastic pin 230 protrudes from the side of the boss 220 near the bottom surface of the groove 120. Thus, when the cartridge 100 and the battery rod 200 are assembled, the elastic pin 230 is compressed and retracts, and the elastic pin 230 presses against the connecting terminal 130 under the pushing of the elastic component, increasing the strength of the connection between the elastic pin 230 and the connecting terminal 130, thereby ensuring good electrical contact between the cartridge 100 and the battery rod 200. The end of the boss 220 away from the elastic pin 230 is provided with a guide groove 221 extending along the first direction. The guide groove 221 has a limiting end near the first insertion interface 121 and a second insertion interface facing away from the first insertion interface 121. The locking assembly includes a protrusion 300 fixed in the slide groove 120 and a locking block 400 elastically disposed in the guide groove 221 along the second direction and corresponding to the protrusion 300. A locking groove 500 is formed between the locking block 400 and the limiting end.In this embodiment, the second insertion interface provides an insertion port for the protrusion 300 to enter the guide groove 221 during the process of the protrusion 220 sliding into the slide groove 120.

[0026] When the boss 220 abuts against the limiting block 122, the elastic pin 230 mates with the connecting terminal 130 to electrically connect the cartridge 100 and the battery rod 200, and the protrusion 300 is located in the slot 500 and abuts against the locking block 400. That is, when the boss 220 on the outer shell 210 of the battery rod is fully inserted into the sliding groove 120 and slides to the maximum distance, the elastic pin 230 is exactly aligned with and abuts against the connecting terminal 130 to realize the electrical connection between the cartridge 100 and the battery rod 200. At the same time, the locking block 400 and the limiting end of the guide groove 221 jointly restrict the protrusion 300 in the slot 500 to lock the cartridge 100 and the battery rod 200. In this embodiment, the protrusion 220 is positioned at one end of the first direction by the limiting block 122, and the cartridge 100 is positioned at the other end of the first direction by the protrusion 300 cooperating with the slot 500, thereby achieving bidirectional positioning of the cartridge 100 and the battery rod 200 along the first direction to prevent the battery rod 200 from falling off the cartridge 100.

[0027] The aforementioned sliding self-locking electronic cigarette structure, by providing a groove 120 on the outer shell 110 of the cartridge and a boss 220 on the outer shell 210 of the battery rod, with the groove 120 and the boss 220 mutually constraining each other, achieves multi-directional limiting of the cartridge 100 and the battery rod 200. By providing a protrusion 300 within the groove 120 and a guide groove 221 on the boss 220 with a resiliently positioned locking block 400, when the battery rod 200 is pushed towards the cartridge 100, the protrusion 300 can engage with the locking groove 500 and resist the locking block 400, thereby locking the cartridge 100 and the battery rod 200 and preventing the cartridge 100 from detaching from the battery rod 200. When the battery rod 200 is pulled away from the cartridge 100 in the opposite direction, the protrusion 300 engages with the locking groove 500 and resists the locking block 400, thus locking the cartridge 100 and the battery rod 200 and preventing the cartridge 100 from detaching from the battery rod 200. Block 300 presses against locking block 400, causing locking block 400 to move and make way for protrusion 300, thereby releasing the lock between cartridge 100 and battery rod 200. Battery rod 200 can then be pulled out of the slide groove 120 of cartridge 100. The disassembly and assembly are simple. After assembly, the mutual constraint between protrusion 300 and locking block 400 improves the stability of the connection between cartridge 100 and battery rod 200. The elastic design of locking block 400 allows it to move under pressure, which helps reduce wear caused by the relative movement of protrusion 300 and locking block 400 during disassembly and assembly. The reliable connection between cartridge 100 and battery rod 200 avoids loosening of electrical connections, ensuring the normal use of the electronic cigarette.

[0028] It should be noted that when the battery rod 200 is arranged below the cartridge 100, the first direction is the width direction (left - right direction) of the outer shell 110 of the cartridge, the second direction is the height direction (up - down direction) of the outer shell 110 of the cartridge, and the third direction is the thickness direction (front - back direction) of the outer shell 110 of the cartridge. The battery rod 200 slides into the chute 120 from the left side below the cartridge 100 to the right side, or slides into the chute 120 from the right side below the cartridge 100 to the left side. When the battery rod 200 is arranged beside the cartridge 100, the first direction is the height direction (up - down direction) of the outer shell 110 of the cartridge, the second direction is the width direction (left - right direction) of the outer shell 110 of the cartridge, and the third direction is the thickness direction (front - back direction) of the outer shell 110 of the cartridge. The battery rod 200 slides into the chute 120 from the left or right side of the cartridge 100 from bottom to top, or slides into the chute 120 from the left or right side of the cartridge 100 from top to bottom. Hereinafter, taking the case where the battery rod 200 is arranged beside the cartridge 100 as an example, the specific structure of the sliding self - locking electronic cigarette structure will be described.

[0029] Please refer to Figure 2-5 , the cross - section of the chute 120 is in a T - shaped structure, or at least one limiting protrusion is provided on the inner side wall of the chute 120, and the cross - sectional shape of the boss 220 is adapted to the cross - sectional shape of the chute 120. In this embodiment, baffles 123 are provided at the edges of the two opposite inner side walls of the chute 120 at the notch, so that the cross - section of the entire chute 120 is in a T - shaped structure. A flange 222 is provided at each of the two side edges of the boss 220. By the corresponding abutment of the flange 222 and the baffle 123, the limit of the boss 220 and the chute 120 in the second direction is achieved. In other embodiments, the cross - section of the chute 120 can also be in a soil - shaped or a structure similar to the character "士", or in other structures with limiting protrusions that can limit the movement of the battery rod 200 in the second direction, which will not be elaborated here.

[0030] In addition, the protrusion 300 has a first inclined surface 310 on the side adjacent to the first insertion interface 121, and a second inclined surface 320 on the side of the protrusion 300 facing away from the first insertion interface 121. The slope of the second inclined surface 320 is greater than the slope of the first inclined surface 310, that is, the protrusion 300 has a trapezoidal platform structure. By setting the first inclined surface 310 and the second inclined surface 320 on the protrusion 300, and making the slope of the second inclined surface 320 greater than the slope of the first inclined surface 310, it is easier for the protrusion 300 to squeeze the locking block 400 and slide into the locking slot 500 after entering the guide groove 221. Moreover, the resistance when the protrusion 300 slides out of the locking slot 500 is greater than the resistance when the protrusion 300 enters the locking slot 500. This reduces the difficulty of the protrusion 300 sliding into the locking slot 500 and the difficulty of assembling the e-cigarette cartridge 100 and the battery rod 200, while ensuring the stability of the structure after the battery rod 200 and the e-cigarette cartridge 100 are assembled. Furthermore, the edge of the cartridge shell 110 is provided with a guide slope 111 near the first insertion interface 121. The guide slope 111 is provided with a wedge-shaped guide block 112 corresponding to the guide groove 221. The side of the wedge-shaped guide block 112 near the shell 210 of the battery rod is flush with the bottom surface of the groove 120. The end face of the boss 220 away from the elastic pin 230 is provided with a clearance groove 223, which corresponds to the second insertion interface. By setting the clearance groove 223, the impact of the wedge-shaped guide block 112 on the end face of the boss 220 during the assembly of the cartridge 100 and the battery rod 200 can be reduced. By setting the wedge-shaped guide block 112, the battery rod 200 is guided and aligned by the sliding cooperation between the wedge-shaped guide block 112 and the second insertion interface, so that the battery rod 200 is aligned with the first insertion interface 121 of the slide groove 120, so that the boss 220 of the battery rod 200 can be smoothly inserted into the slide groove 120, thereby reducing the assembly difficulty of the cartridge 100 and the battery rod 200.

[0031] The cartridge 100 includes a mouthpiece 140 fixed to the top of the cartridge shell 110 and communicating with the inner cavity of the cartridge shell 110; an oil tank 150 disposed in the inner cavity of the cartridge shell 110 for holding e-liquid; an atomizing core disposed in the inner cavity of the cartridge shell 110 and communicating with the oil tank 150 for heating and atomizing the e-liquid; and a first PCB board 160 disposed in the inner cavity of the cartridge shell 110 and electrically connected to the atomizing core. An air inlet 113 communicating with the atomizing core is provided on the bottom or side of the cartridge shell 110. A sliding cover is provided at the air inlet 113 to slidably seal the air inlet and prevent e-liquid leakage when the e-cigarette is not in use. The top of the atomizing core communicates with the mouthpiece 140, and the top of the mouthpiece 140 has a suction port 141 communicating with the external environment. A mouthpiece cap is detachably covered at the suction port. In this embodiment, the atomizing core includes an atomizing tube 170 that runs through the top and bottom of the oil tank 150 and communicates with the mouthpiece 140, an oil storage cotton 180 that surrounds the atomizing tube 170 and is immersed in the e-liquid in the oil tank 150, and a heating element 190 that is housed in the atomizing tube 170 and electrically connected to the first PCB board 160 to heat and atomize the e-liquid. The heating element 190 can be a ceramic heating element, a metal heating wire, or a metal heating mesh. The atomizing tube 170 has several oil inlet holes 191 penetrating its inner and outer surfaces at locations corresponding to the heating element 190. The oil reservoir 180 has several micropores. These micropores provide a channel for e-liquid from the oil tank 150 to enter the atomizing tube 170, diverting the e-liquid and increasing its heating area, thereby improving atomization. Simultaneously, they increase the resistance to e-liquid entering the atomizing tube 170 to prevent excessive flow and leakage at the mouthpiece 140. An oil-separating ring 171 is provided at the connection between the atomizing tube 170 and the air inlet 113. This ring has numerous pores and is used to block large droplets of e-liquid, improving the user's vaping experience. Preferably, the oil-separating ring 171 is made of sponge.

[0032] Please combine Figure 4-8The connecting terminal 130 includes a first end inserted into the outer shell 110 of the cartridge and a second end facing away from the first end. The cartridge 100 also includes at least one first spring piece 161 soldered to the first PCB board 160 and corresponding to each connecting terminal 130. The middle part of the first spring piece 161 is bent, and the two ends of the first spring piece 161 are arranged opposite to each other, forming a snap-fit ​​area 162 with adjustable width for the first end to be inserted between the two ends of the first spring piece 161. By setting the first spring piece 161 soldered to the first PCB board 160 and clamping the first end of the connecting terminal 130 with the two ends of the first spring piece 161, a stable connection between the connecting terminal 130 and the first spring piece 161 can be achieved, and good electrical contact between the connecting terminal 130 and the first PCB board 160 can be ensured. It can also simplify the assembly connection between the connecting terminal 130 and the first PCB board 160. It should be noted that in this embodiment, the side of the second end facing away from the first end is flush with the bottom surface of the groove 120. That is to say, the side of the connecting terminal 130 facing the battery rod 200 is a flat surface, so as to avoid the problem of poor contact between the elastic pin 230 and the connecting terminal 130 caused by the deposition of impurities on the concave surface when the surface is concave.

[0033] Please combine Figure 2-3 as well as Figure 7-8The battery rod 200 includes a partition 240, a battery 250, a second spring 260, and a second PCB board 270 housed within a housing 210 of the battery rod. The partition 240 separates the inner cavity of the housing 210 of the battery rod to form a battery compartment 211 and an elastic adjustment area 212. The battery 250 and the second PCB board 270 are housed within the battery compartment 211. The second PCB board 270 is electrically connected to the battery 250 and the elastic pin 230, respectively. The second spring 260 is housed within the elastic adjustment area 212 and is fixedly connected to the partition 240. A guide groove 221 is provided on the side of the housing 210 of the battery rod facing away from the battery compartment 211, and a through hole communicating with the elastic adjustment area 212 is provided in the guide groove 221. The locking block 400 is fixedly connected to the elastic part of the second spring 260 and passes through the through hole. Furthermore, in this embodiment, a microphone 280 electrically connected to the second PCB board 270 is provided below the battery compartment 211 and the elastic adjustment area 212. A first hole 224 corresponding to the microphone 280 is opened on the side of the boss 220 adjacent to the tobacco cartridge 100, and an annular protective silicone 225 is provided at the first hole 224. A second hole 114 communicating with the air inlet 113 and corresponding to the first hole 224 is opened on the side of the outer shell 110 of the tobacco cartridge. After the tobacco cartridge 100 and the battery rod 200 are assembled, the first hole 224 and the second hole 114 are connected. In this way, when the user inhales through the mouthpiece 140, a negative pressure is generated at the mouthpiece 140. During this process, external gas enters the atomizing tube 170 through the air inlet 113, and through the connection between the first hole 224 and the second hole 114, a negative pressure is also generated at the microphone 280 to trigger the microphone 280. Furthermore, through the electrical connection between the flexible pin 230 and the connecting terminal 130, the heating element 190 is controlled by the first PCB board 160. Thus, the e-liquid adsorbed on the oil storage cotton 180 enters the atomizing tube 170 through the oil inlet 191 under the action of negative pressure and is heated by the heating element 190 to form an oil mist. This oil mist is inhaled into the user's mouth and nose along with the airflow to provide the user with vapor that can be inhaled.

[0034] Please combine Figure 8-9 The second spring 260 has an M-shaped structure, with an elastic portion formed in the middle. The locking block 400 is screwed onto the elastic portion, or the locking block 400 and the elastic portion are integrally formed. Of course, in other embodiments, the second spring 260 can also have a straight or arc-shaped structure, ensuring that the elastic portion is located in the middle of the second spring 260 and that the elastic portion deforms when the locking block 400 is compressed to provide a restoring force for the locking block 400 to return to its original position. Other structures for the second spring 260 are also possible, which will not be elaborated here.

[0035] In one embodiment, a display screen electrically connected to the second PCB board 270 is provided on a side of the battery rod housing 210 opposite to the side where the boss 220 is located, and a control button 290 is also provided on the same side of the battery rod housing 210 opposite to the side where the boss 220 is located to start and stop the electronic cigarette. By providing a display screen on the battery rod housing 210, the user can view the operating parameters of the electronic cigarette, such as battery level and e-liquid remaining. The display screen can be installed on the battery rod housing 210 in a built-in or external manner. When the display screen is built into the battery rod housing 210, a transparent protective cover 291 is provided on the battery rod housing 210 to cover the display screen. The transparency of the transparent protective cover 291 is greater than 30% so that the user can see the corresponding display content. Of course, depending on the product appearance design, the display screen can also be set on the housing 110 of the e-liquid cartridge. The surface of the battery rod housing 210 and / or the housing 110 of the e-liquid cartridge is also provided with anti-slip texture to prevent the user from slipping when holding the electronic cigarette.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
