Technical Field
[0001] This utility model relates to the field of electronic cigarettes, and more particularly to electronic cigarettes with a cigarette holder. Background Technology
[0002] For e-cigarettes, especially heated tobacco products, there are frequent issues such as cartridge breakage upon removal after use and contamination of the heating chamber after cartridge combustion. To address these issues, those skilled in the art have added a cigarette extractor to the e-cigarette head that engages with the heating chamber. During use, the cigarette is inserted into the extractor, which fits into the heating chamber. After use, the extractor can be removed from the heating chamber to retrieve the cigarette. However, this extractor is typically sleeve-shaped. When inserting the cigarette, the sleeve-shaped extractor needs to clamp it tightly. While this prevents the cigarette from breaking off inside the heating chamber during removal, the tightness of the engagement with the heating chamber makes it difficult to remove or insert the extractor if the engagement is too tight, and it can easily detach during use if the engagement is too loose.
[0003] Therefore, there is an urgent need for an electronic cigarette that can solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an electronic cigarette with a cigarette holder, which makes the cigarette holder highly stable after being inserted into the housing, not easy to fall off, and easy to insert and remove.
[0005] To achieve the above objectives, this utility model provides an electronic cigarette with a lifting device, comprising a housing, a power supply module, a control module, a heating component, and a lifting device installed in the housing. The control module controls the power supply module to heat the heating component. The top of the housing has a heating groove for accommodating a tobacco cartridge. The heating component is installed at a corresponding position in the heating groove to heat the tobacco cartridge in the heating groove. The lifting device includes a top cover that cooperates with the housing and closes the opening at the top of the housing. The lower end face of the top cover has a protruding part that inserts into the heating groove. The accompanying cartridge positioning frame has a cartridge mounting cavity for accommodating the cartridge. The upper cover has a cartridge inlet that penetrates the heating groove. The cartridge can pass through the cartridge inlet and be inserted into the cartridge mounting cavity. When the cartridge positioning frame is inserted into the heating groove, the cartridge mounting cavity is located in the heating groove. The cigarette lifter and the housing are respectively equipped with magnetic suction components that are positioned opposite each other and magnetically attracted to each other, so that when the cartridge positioning frame is inserted into the heating groove, the cigarette lifter and the housing are magnetically positioned together by the magnetic suction components.
[0006] Preferably, the top of the housing is provided with a positioning groove, and the lower side of the upper cover is provided with a positioning block that convexly and concavely engages with the positioning groove. The magnetic suction assembly is installed in the housing near the positioning groove and in the positioning block.
[0007] Specifically, the magnetic attraction assembly includes a magnet block installed inside the positioning block and an electromagnet installed on the outside of the positioning groove wall. A metal shield is installed on the outside of the positioning groove wall and houses the electromagnet therein, so as to shield the electromagnet from magnetism in directions other than the direction toward the positioning groove wall, effectively preventing the electromagnet from affecting the operation of the heating assembly.
[0008] More specifically, an electromagnet mounting bracket is provided on the outer side of the positioning groove wall in a direction away from the positioning groove, the electromagnet is installed in the electromagnet mounting bracket, and the metal shielding cover is placed over the electromagnet mounting bracket.
[0009] Preferably, one or more cleaning windows for cleaning the cartridge are provided on the side wall of the cartridge mounting cavity.
[0010] More preferably, the cartridge positioning rack includes an annular base and a plurality of positioning strips arranged circumferentially along the edge of the base and fixedly connected to the base. The cross-section of the plurality of positioning strips is an arc centered on the center line of the cartridge positioning rack. The plurality of positioning strips enclose the cartridge mounting cavity. The cleaning window is formed between two adjacent positioning strips. This design makes the cartridge positioning rack a frame structure that is easy to clean.
[0011] More preferably, the sidewall of the heating tank has several clamping strips protruding outward at positions corresponding to the cleaning window. These clamping strips are arranged longitudinally and have an inclined guide wall at their front end to guide the tobacco cartridge into the tank. Several positioning blocks protrude from the cavity wall of the tobacco cartridge inlet. The clamping strips and positioning blocks are distributed around the heating tank at intervals around the center line. When the tobacco cartridge positioning bracket is inserted into the heating tank, the clamping strips extend into the tobacco cartridge mounting cavity, and the clamping strips and positioning blocks clamp the tobacco cartridge tightly when it is inserted into the heating tank. This design not only ensures stable positioning of the tobacco cartridge after it enters the heating tank but also creates a certain gap between the tobacco cartridge and the tank wall, forming an air intake channel during smoking. Furthermore, it prevents the heat from the tobacco cartridge from excessively affecting the tank wall.
[0012] Specifically, the bottom center of the cartridge mounting cavity has an air inlet hole, and the wall and bottom of the heating groove do not have through holes. The bottom has several air inlet grooves around the air inlet hole that communicate with the air inlet hole of the cartridge mounting cavity. When the cartridge is inserted into the cartridge mounting cavity and the heating groove, the clamping strip forms an air inlet channel communicating with the air inlet groove between the cartridge and the wall of the heating groove. This design eliminates the need to form a separate air inlet channel in the housing, and since the wall and bottom of the heating groove have no through holes, the air inlet channel will not be blocked by ash falling in.
[0013] Specifically, the bottom of the heating groove has one or more protrusions. The groove walls and bottom do not have through holes. When the cigarette holder is not inserted into the heating groove but the cigarette cartridge is inserted, the cigarette cartridge abuts against the protrusions, forming a bottom air intake area between the cigarette cartridge and the protrusions. The clamping strip creates an air intake channel between the cigarette cartridge and the groove wall, communicating with the bottom air intake area. This design allows the invention to be used directly without the cigarette holder, and the absence of through holes in the groove walls and bottom prevents ash from clogging the air intake channel.
[0014] Preferably, a dust cover is installed on the top of the upper cover. The dust cover is slidably installed on the upper cover and can open or close the cartridge inlet relative to the upper cover. This design allows the cartridge inlet to be closed by the dust cover when not in use, preventing dust from falling into the heating tank.
[0015] Preferably, the housing has a fixed bracket, and the heating assembly and part of the magnetic attraction assembly are mounted on the fixed bracket.
[0016] Preferably, the heating assembly includes an electromagnetic induction coil surrounding the wall of the heating tank, and an electromagnetic induction element protruding from the bottom of the heating tank or inside the cartridge. The electromagnetic induction coil is surrounded by a shielding layer. The control module controls the power supply module to supply power to the electromagnetic induction coil so that the electromagnetic induction coil generates a high-frequency signal, and the electromagnetic induction element senses the high-frequency signal and generates heat.
[0017] Compared with the prior art, this utility model uses a magnetic attachment component to position the cigarette holder and the e-cigarette shell, so that the cigarette holder and the e-cigarette shell only need a basic concave-convex fit. This not only makes it easy to insert and remove the cigarette holder, but also makes the structure highly stable after the cigarette holder is inserted into the shell, and it is not easy to fall off.

[0027] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0028] refer to Figures 1 to 8This invention discloses an electronic cigarette 100 with a cigarette holder 20, comprising a housing 10, a power supply module 33, a control module 32, a heating component 31, and a cigarette holder 20 installed in the housing 10. The control module 32 controls the power supply module 33 to heat the heating component 31. The top of the housing 10 has a heating groove 11 for accommodating a cigarette cartridge 200. The heating component 31 is installed at a corresponding position in the heating groove 11 to heat the cigarette cartridge 200 in the heating groove 11. The cigarette holder 20 includes a top cover 21 that can cooperate with the housing 10 and close the top opening of the housing 10. The lower end face of the top cover 21 has a protruding part that inserts into the heating groove 11. The cartridge positioning frame 22 has a cartridge mounting cavity 220 formed on it to accommodate the cartridge 200. The upper cover 21 has a cartridge inlet 21 that penetrates the heating groove 11. The cartridge can pass through the cartridge inlet 21 and be inserted into the cartridge mounting cavity 220. When the cartridge positioning frame 22 is inserted into the heating groove 11, the cartridge mounting cavity 220 is located in the heating groove 11. The cigarette lifter 20 and the housing 10 are respectively equipped with magnetic suction components 40 that are positioned opposite each other and magnetically attracted to each other, so that when the cartridge positioning frame 22 is inserted into the heating groove 11, the cigarette lifter 20 and the housing 10 are magnetically positioned together by the magnetic suction components 40.
[0029] refer to Figure 4 and Figure 5 The top of the housing 10 is also provided with a positioning groove 12, and the lower side of the upper cover 21 is also provided with a positioning block 23 that convexly and concavely engages with the positioning groove 12. (Reference) Figure 7 and Figure 8 The magnetic suction component 40 is installed in the housing 10 near the positioning groove 12 and in the positioning block 23. Of course, the magnetic suction component 40 can also be installed in other locations such as the top cover 21 of the cigarette lifter 20 and the top opening of the housing 10, or at the bottom of the cigarette cartridge positioning frame 22 and below the bottom of the heating groove 11.
[0030] refer to Figure 7 and Figure 8The magnetic attraction assembly 40 includes a magnet block 41 installed in the positioning block 23 and an electromagnet 42 installed on the outer side of the positioning groove 12. A metal shielding cover 14 is installed on the outer side of the positioning groove 12 and houses the electromagnet 42 therein, thereby shielding the electromagnet 42 from magnetism in directions other than the direction towards the groove wall of the positioning groove 12, effectively preventing the electromagnet 42 from affecting the operation of the heating assembly 31. An electromagnet mounting bracket 13 protrudes from the outer side of the positioning groove 12 in a direction away from the positioning groove 12. The electromagnet 42 is installed in the electromagnet mounting bracket 13, and the metal shielding cover 14 covers the electromagnet mounting bracket 13. In this embodiment, the magnetic attraction component 40 is installed in the positioning groove 12 and the positioning block 23 in a vertically opposite direction. However, the magnetic attraction component 40 can also be installed in a laterally opposite position after the positioning groove 12 and the positioning block 23 are engaged. For example, the electromagnet 42 can surround the side wall of the positioning groove 12, and the magnet block 41 can be located inside the positioning block 23 so that after the positioning block 23 is inserted into the positioning groove 12, the electromagnet 42 surrounds the magnet block 41. Of course, the electromagnet 42 can also be replaced by a permanent magnet with the opposite magnetism to the magnet block 41.
[0031] refer to Figure 5 The side wall of the cartridge mounting cavity 220 is provided with one or more cleaning windows for cleaning the cartridge. In this embodiment, there are two cleaning windows positioned opposite each other. (See reference...) Figure 5 and Figure 9 The cartridge positioning frame 22 includes an annular base 222 and multiple positioning strips 221 arranged circumferentially along the edge of the base 222 and fixedly connected to the base 222. The cross-section of the multiple positioning strips 221 is an arc centered on the center line of the cartridge positioning frame 222. The multiple positioning strips 221 enclose the cartridge mounting cavity 220. The cleaning window is formed between two adjacent positioning strips 221. This design makes the cartridge positioning frame 22 a frame structure, which is easy to clean. In this embodiment, there are two positioning strips 221 arranged opposite each other circumferentially along the base 220. Of course, the number of cleaning windows is not limited to one or two, but can also be three, four, etc. The cleaning windows can be distributed longitudinally on the entire cartridge mounting cavity 220, or located in the lower half of the cartridge mounting cavity 220.
[0032] refer to Figures 7 to 9The heating groove 11 has several clamping strips 111 protruding outward on its sidewall at positions corresponding to the cleaning window. These clamping strips 111 are longitudinally arranged and have an inclined guide wall at their front end to guide the tobacco cartridge into the groove. Several positioning blocks 23 protrude from the cavity wall of the tobacco cartridge inlet 21. The clamping strips 111 and positioning blocks 23 are distributed around the heating groove 11 at intervals around the center line. When the tobacco cartridge positioning frame 22 is inserted into the heating groove 11, the clamping strips 111 extend into the tobacco cartridge mounting cavity 220. When the tobacco cartridge 200 is inserted into the heating groove 11, the clamping strips 111 and positioning blocks 23 clamp the tobacco cartridge. This design not only ensures stable positioning of the tobacco cartridge after it enters the heating groove 11, but also creates a certain gap between the tobacco cartridge and the groove wall of the heating groove 11, forming an air intake channel 113 for smoking. Furthermore, it prevents excessive heat transfer from the tobacco cartridge 200 to the groove wall of the heating groove 11.
[0033] Specifically, the bottom 222 of the cartridge mounting cavity 220 has an air inlet 223 in the middle. The wall and bottom of the heating groove 11 do not have through holes. The bottom 222 has several air inlet grooves 224 around the air inlet 223, which communicate with the air inlet 223 of the cartridge mounting cavity 220. When the cartridge is inserted into the cartridge mounting cavity 220 and the heating groove 11, the clamping strip 111 forms an air inlet channel 113 between the cartridge and the wall of the heating groove 11, which communicates with the air inlet grooves 224. This design eliminates the need for a separate air inlet channel 113 in the housing 10, and since the wall and bottom of the heating groove 11 have no through holes, the air inlet channel 113 will not be blocked by ash falling in. The air inlet 223 is a through hole, but it can also be a closed-bottom groove. The bottom 222 has grooves spaced around the air inlet 223, which form an air inlet groove 224.
[0034] Specifically, the bottom of the heating groove 11 is provided with one or more protrusions 112. The groove wall and bottom of the heating groove 11 do not have through holes. When the cigarette holder 20 is not inserted into the heating groove 11 but the cigarette cartridge is inserted, the cigarette cartridge abuts against the protrusions 112, forming a bottom air intake area between the cigarette cartridge 200 and the protrusions 112. The clamping strip 111 forms an air intake channel 113 between the cigarette cartridge and the groove wall of the heating groove 11, communicating with the bottom air intake area. This design allows the invention to be used directly without the cigarette holder 20, and since the groove wall and bottom of the heating groove 11 have no through holes, the air intake channel 113 will not be blocked by cigarette ash. In this embodiment, there are two protrusions 112, which are semi-circular in shape. The two semi-circular protrusions 112 are spaced relatively close together, with the recessed areas spaced relatively close together, forming an annular protrusion with a radial diameter smaller than the cross-sectional area of the cigarette cartridge 200.
[0035] The top of the upper cover 21 is equipped with a dust cover 201. The dust cover 201 is slidably mounted on the upper cover 21 via a sliding groove 202 and can open or close the cartridge inlet 21 relative to the upper cover 21 to prevent dust from falling into the heating groove 11 when not in use. The sliding groove 202 is formed on the top of the upper cover 21 and is arranged laterally perpendicular to the center line of the heating groove 11.
[0036] The housing 10 has a fixed bracket 101 inside, and the heating component 31 and part of the magnetic attraction component 40 (electromagnet 42) are mounted on the fixed bracket 101.
[0037] The heating assembly 31 includes an electromagnetic induction coil 311 surrounding the wall of the heating tank 11, and an electromagnetic induction element (not shown) protruding from the bottom of the heating tank 11 or inside the cartridge. The electromagnetic induction coil 311 is surrounded by a shielding layer 312. The control module 32 controls the power supply module 33 to supply power to the electromagnetic induction coil 311 so that the electromagnetic induction coil 311 generates a high-frequency signal. The electromagnetic induction element senses the high-frequency signal and generates heat.
[0038] Compared with the prior art, the present invention uses a magnetic attachment component 40 to position the cigarette holder 20 and the electronic cigarette housing 10, so that the cigarette holder 20 and the electronic cigarette housing 10 only need a basic concave-convex fit. This not only makes it easy to insert and remove the cigarette holder 20, but also makes the structure of the cigarette holder 20 highly stable after being inserted into the housing 10, and it is not easy to fall off.
[0039] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model shall still fall within the scope of the present utility model.
