Description

Technical Field

[0001] The present invention belongs to the technical field of electronic smoking devices, and in particular relates to a rotary clamping type electronic smoking device. Background Art

[0002] Heat-not-burn cigarettes are different from traditional cigarettes. Designed with the concept of "heating without burning," they heat the tobacco leaves just enough to release their flavor without igniting them. Normally, ordinary cigarettes produce numerous harmful substances at high temperatures of 350°C to 600°C when smoked, while low-temperature cigarettes are heated below 300°C, which reduces harmful substances. Specifically, taking emissions as an example, heat-not-burn tobacco products emit only about 5% of traditional tobacco. From a cytotoxicity perspective, heat-not-burn tobacco products are about 14% of traditional cigarettes.

[0003] In addition, heat-not-burn products are closer to traditional cigarettes in taste and smoking experience, allowing smokers to feel the real tobacco flavor and are more easily accepted.

[0004] Existing non-combustion electronic smoking devices heat cigarettes to generate smoke through electric heating. That is, the non-combustion electronic smoking device has a heating chamber for accommodating cigarettes, and a heating rod is provided in the heating chamber. By inserting the cigarette into the heating chamber of the non-combustion electronic smoking device and inserting the heating rod into the center of the cigarette, the heating circuit of the heating rod is activated to generate heat to heat the cigarette, so that the cigarette produces smoke for the user to inhale.

[0005] However, when heating a cigarette using a non-combustion electronic cigarette device of this structure, after smoking is completed, when the cigarette is removed from the cigarette device, the tobacco in the cigarette often sticks to the heating rod, so that the lid of the cigarette device needs to be opened to clean the heating rod before the next cigarette can be used. Summary of the Invention

[0006] The purpose of the present invention is to provide a rotating clamping electronic smoking device to solve the problem that tobacco in a cigarette sticks to a heating rod due to structural defects of existing smoking devices, so that the lid of the smoking device needs to be opened to clean the heating rod before the next cigarette can be used.

[0007] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0008] A rotary clamping electronic cigarette device comprises a main body, a heating mechanism and a lifting cylinder, wherein the main body is fixedly connected with a connecting cylinder, the heating mechanism is installed on the main body and is located in the connecting cylinder, a heating rod is fixedly installed on the heating mechanism, the lifting cylinder is passed through the connecting cylinder and sleeved on the heating mechanism, an annular support platform sleeved on the heating rod is integrally formed on the inner wall of the lifting cylinder above the heating mechanism, a spiral sliding groove is opened on the inner wall of the connecting cylinder, a clamping column is fixedly installed on the outer wall of the lifting cylinder, the clamping column is located in the spiral sliding groove, a limit platform is fixedly provided on the upper end of the lifting cylinder above the connecting cylinder, and the lifting cylinder is sleeved on the limit A bearing is installed above the positioning platform, and a mounting ring is installed above the bearing of the lifting cylinder. A pushing sleeve is slidably installed on the connecting cylinder, and the pushing sleeve is fixedly provided with a connecting seat above the connecting cylinder. The connecting seat is fixedly connected to the outer ring of the bearing, and two hinged columns are fixedly installed on the mounting ring. The mounting ring is hinged with an arc-shaped block through the hinged column, and a torsion spring is installed between the arc-shaped block and the mounting ring. A blocking block is integrally formed on the outer side surface of the arc-shaped block, and a first bayonet is provided on the blocking block. An outer ring is fixedly installed on the connecting seat, and two positioning columns are fixedly installed on the outer ring, and the positioning columns are located in the first bayonet.

[0009] The mounting ring is further defined as having a first mounting blind hole, the hinge post is positioned within the first mounting blind hole, the arc-shaped clamping block has a stepped hole extending from bottom to top, the torsion spring is sleeved on the hinge post and positioned within the first mounting blind hole and the stepped hole, and a limit plate is fixedly mounted above the arc-shaped clamping block. This structural design, in which the torsion spring is sleeved on the hinge post and contained within the first mounting blind hole and the stepped hole, prevents the torsion spring from being exposed and potentially causing safety hazards.

[0010] The hinge post is further defined as having a hexagonal blind hole, a threaded hole at the bottom of which is formed on the hinge post, a hexagonal boss integrally formed on the lower end surface of the limit plate, a through-hole formed on the limit plate, a screw passing through the through-hole, and the screw being threadedly engaged with the threaded hole. This structural design, through the mutual matching of the hexagonal boss and the hexagonal blind hole, prevents the limit plate from loosening due to the rotation of the arc-shaped clamping block, resulting in a simple structure and easy installation.

[0011] Furthermore, the arc-shaped clamping block is provided with a second clamping opening, and the mounting ring is fixedly provided with a blocking post. This structural design limits the maximum twisting position of the arc-shaped clamping block under the action of the torsion spring, thereby preventing the arc-shaped clamping block from excessively clamping the cigarette and thereby damaging the cigarette.

[0012] It is further defined that the bearing is a double-direction thrust angular contact ball bearing. With such a structural design, the double-direction thrust angular contact ball bearing can bear greater axial thrust than ordinary deep groove ball bearings and is more suitable for this application.

[0013] It is further defined that the outer wall of the push sleeve is provided with a positioning groove, the outer wall of the connecting tube is provided with a block mounted at the upper end of the positioning groove, the block having a through hole, the push sleeve further provided with a guide rod mounted within the positioning groove, the guide rod being inserted into the through hole, the guide rod being provided with a compression spring mounted within the positioning groove, the compression spring being located below the block. With this structural design, after the push sleeve is pushed upward to drive the lifting tube upward, the push sleeve is released, and the push sleeve can move downward under the action of the compression spring, thereby driving the lifting tube to descend and reset, facilitating the next use.

[0014] It is further defined that the push sleeve has a positioning hole at the top of the positioning groove, the upper end of the guide rod is inserted into the positioning hole, the push sleeve has a through hole at the bottom of the positioning groove, and the push sleeve further has a threaded blind hole at the lower end. The threaded blind hole and the through hole are coaxial and interconnected, and a bolt is screwed into the threaded blind hole. With this structural design, when installing the guide rod and the compression spring, the compression spring can be first placed in the positioning groove, and then the guide rod can be inserted through the threaded blind hole, so that the guide rod is inserted into the compression spring and the top end of the guide rod is inserted into the positioning hole. Finally, the bolt is screwed into the threaded blind hole, and the guide rod is installed, which is convenient.

[0015] Furthermore, the push sleeve is provided with a notch at its lower portion on a side away from the positioning groove. This structural design exposes the lower sidewall of the connecting tube on the side away from the positioning groove through the notch. When in use, after holding the main body, the user can place the index and middle fingers on the connecting tube exposed by the notch, and then use the thumb to push the push sleeve, making it more convenient to use.

[0016] The invention adopting the above technical solution has the following advantages:

[0017] 1. The lifting cylinder, the clamping column, the spiral sliding groove, the bearing, the arc-shaped clamping block, the blocking block, the torsion spring, and the compression spring cooperate with each other to make the lifting cylinder rotate as it rises. This in turn drives the cigarette fixed by the arc-shaped clamping block in the lifting cylinder to rotate relative to the heating rod. The friction between the cigarette and the heating rod causes tobacco stuck to the heating rod to fall off.

[0018] 2. Through the interaction of the arc-shaped block, the blocking block, the torsion spring, and the positioning column, when the push sleeve is pushed to a certain height, the outer ring drives the arc-shaped block around the hinge column, overcoming the prestress of the torsion spring to rotate counterclockwise, thereby completely exposing the middle of the mounting ring and the lifting cylinder, making it easier to put in cigarettes and loosen the clamping force on the cigarettes to facilitate their removal.

[0019] 3. By utilizing the interaction between the arc-shaped block, the blocking block and the torsion spring, the arc-shaped block can rotate clockwise around the hinge column at a certain angle under the action of the torsion spring in the middle and late stages of the descent process and the early and middle stages of the ascent process of the lifting cylinder, thereby clamping the cigarette.

[0020] 4. The lifting cylinder and the pushing sleeve are connected by the bearing, and the mutual matching of the block and the positioning groove can prevent the lifting cylinder from driving the pushing sleeve to rotate during the rotation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions, similar or identical parts are numbered the same. Implementations not shown or described in the drawings are forms known to those of ordinary skill in the art. In addition, directional terms mentioned in the embodiments, such as "upper," "lower," "top," "bottom," "left," "right," "front," and "back," are merely references to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0040] like Figures 1 to 7 As shown, a rotary clamping electronic smoking device of the present invention includes a main body 1, a heating mechanism 2 and a lifting cylinder 3. The main body 1 is fixedly connected to a connecting cylinder 11, the heating mechanism 2 is installed on the main body 1 and is located in the connecting cylinder 11, a heating rod 21 is fixedly installed on the heating mechanism 2, the lifting cylinder 3 is passed through the connecting cylinder 11 and sleeved on the heating mechanism 2, and an annular support platform 31 sleeved on the heating rod 21 is integrally formed on the inner wall of the lifting cylinder 3 above the heating mechanism 2, a spiral sliding groove 41 is opened on the inner wall of the connecting cylinder 11, a clamping column 42 is fixedly installed on the outer wall of the lifting cylinder 3, and the clamping column 42 is located in the spiral sliding groove 41. A limit platform 32 is fixedly provided on the upper end of the lifting cylinder 3 above the connecting cylinder 11. A bearing 6 is installed above the limit platform 32, and a mounting ring 8 is installed above the bearing 6 of the lifting cylinder 3. A pushing sleeve 7 is slidably installed on the connecting cylinder 11. The pushing sleeve 7 is fixedly provided with a connecting seat 70 above the connecting cylinder 11. The connecting seat 70 is fixedly connected to the outer ring of the bearing 6. Two hinged columns 81 are fixedly installed on the mounting ring 8. The mounting ring 8 is hinged with an arc-shaped block 5 through the hinged columns 81. A torsion spring 80 is installed between the arc-shaped block 5 and the mounting ring 8. A blocking block 51 is integrally formed on the outer side surface of the arc-shaped block 5. A first bayonet 510 is opened on the blocking block 51. An outer ring 9 is fixedly installed on the connecting seat 70. Two positioning columns 91 are fixedly installed on the outer ring 9. The positioning columns 91 are located in the first bayonet 510.

[0041] The mounting ring 8 defines a first blind mounting hole 810, within which the hinge post 81 is located. The arc-shaped clamping block 5 defines a stepped hole 50 from bottom to top. A torsion spring 80 is mounted on the hinge post 81 and positioned within the first blind mounting hole 810 and the stepped hole 50. The hinge post 81 is fixedly mounted above the arc-shaped clamping block 5 to the limit plate 61. The torsion spring 80 is mounted on the hinge post 81 and contained within the first blind mounting hole 810 and the stepped hole 50, preventing exposure of the torsion spring 80 and the resulting safety hazards.

[0042] Hinge post 81 has a hexagonal blind hole 620, with a threaded hole at the bottom. A hexagonal boss 62 is integrally formed on the lower end surface of stop plate 61. Stop plate 61 has a through-hole 610, through which a screw is inserted and threadedly engaged. The mating of hexagonal boss 62 and hexagonal blind hole 620 prevents loosening of stop plate 61 due to rotation of arc-shaped clamping block 5, resulting in a simple structure and easy installation.

[0043] The arc-shaped clamping block 5 is further provided with a second clamping opening 520, and a stopper 52 is fixedly mounted on the mounting ring 8. The stopper 52 limits the maximum twisting position of the arc-shaped clamping block 5 under the action of the torsion spring 80, thereby preventing the arc-shaped clamping block 5 from excessively clamping the cigarette and thereby damaging the cigarette.

[0044] The bearing 6 is a double-direction thrust angular contact ball bearing. Compared with ordinary deep groove ball bearings, double-direction thrust angular contact ball bearings can carry greater axial thrust and are more suitable for this application.

[0045] A positioning groove 71 is formed on the outer wall of the push sleeve 7. A stopper 110 is mounted on the outer wall of the connecting tube 11 at the upper end of the positioning groove 71. A through hole is formed in the stopper 110. A guide rod 72 is further mounted in the positioning groove 71 of the push sleeve 7. The guide rod 72 passes through the through hole. A compression spring 720 is sleeved on the guide rod 72 in the positioning groove 71. The compression spring 720 is located below the stopper 110. After the push sleeve 7 is pushed upward to drive the lifting tube 3 upward, the push sleeve 7 is released. The push sleeve 7 can move downward under the action of the compression spring 720, thereby driving the lifting tube 3 to descend and reset, facilitating the next use.

[0046] The push sleeve 7 has a positioning hole at the top of the positioning groove 71. The upper end of the guide rod 72 is inserted into the positioning hole. The push sleeve 7 has a through hole at the bottom of the positioning groove 71. The push sleeve 7 also has a threaded blind hole at the lower end. The threaded blind hole and the through hole are coaxial and interconnected. A bolt is screwed into the threaded blind hole. When installing the guide rod 72 and the compression spring 720, the compression spring 720 can be placed in the positioning groove 71 first, and then the guide rod 72 is inserted through the threaded blind hole. The guide rod 72 is inserted into the compression spring 720, and the top end of the guide rod 72 is inserted into the positioning hole. Finally, the bolt is screwed into the threaded blind hole. The installation of the guide rod 72 is completed, which is convenient.

[0047] A notch 701 is formed in the lower portion of the push sleeve 7 on the side away from the positioning groove 71. The notch 701 exposes the lower sidewall of the connecting tube 11 on the side away from the positioning groove 71. When in use, after holding the main body 1, the index and middle fingers can be placed on the connecting tube 11 exposed by the notch 701, and the thumb can be used to push the push sleeve 7, which is more convenient to use.

[0048] In this embodiment, when in use, the user holds the main body 1 with the index and middle fingers resting on the connecting tube 11 exposed by the notch 701, and then uses the thumb to push the push sleeve 7 upward, so that the push sleeve 7 drives the outer ring 9 to rise linearly, and the lifting tube 3 spirally rises in the connecting tube 11 through the interaction between the clamping column 42 and the spiral sliding groove 41;

[0049] During this process, the mounting ring 8 and the outer ring 9 rotate relative to each other (i.e., the mounting ring 8 rotates clockwise relative to the outer ring 9) until the first retaining opening 510 of the blocking block 51 abuts against the positioning post 91. Continuing to push, the blocking block 51 is blocked by the positioning post 91, thereby overcoming the prestress of the torsion spring 80 and driving the arc-shaped blocking block 5 to rotate counterclockwise around the hinge post 81, thereby exposing the hole between the mounting ring 8 and the lifting cylinder 3. Then, a cigarette is inserted into the lifting cylinder 3, causing it to abut against the annular support platform 31, and the push on the pushing sleeve 7 is released.

[0050] After the push sleeve 7 is released, the push sleeve 7 moves downward under the action of the compression spring 720, driving the lifting cylinder 3 downward through the bearing 6. The locking column 42 and the spiral sliding groove 41 then match each other, causing the lifting cylinder 3 to rotate counterclockwise relative to the outer ring 9, thereby causing the blocking block 51 to disengage from the positioning column 91. At this time, the arc-shaped locking block 5 rotates clockwise around the hinge column 81 under the action of the torsion spring 80, thereby clamping the cigarette inserted in the lifting cylinder 3.

[0051] The push sleeve 7 continues to move downward, thereby driving the cigarette held by the arc-shaped clamping block 5 to spirally descend, so that the cigarette is placed on the heating rod 21;

[0052] After smoking is finished, the user holds the smoking device and pushes the push sleeve 7 upward again, driving the cigarette to spirally rise through the lifting cylinder 3, thereby driving the cigarette fixed by the arc-shaped clamping block 5 in the lifting cylinder 3 to rotate relative to the heating rod 21. The friction between the cigarette and the heating rod 21 causes the tobacco adhered to the heating rod 21 to fall off, until the first clamping opening 510 of the blocking block 51 again abuts against the positioning column 91, driving the arc-shaped clamping block 5 to rotate counterclockwise around the hinge column 81, loosening the clamping of the cigarette. At this time, the cigarette in the lifting cylinder 3 can be taken out;

[0053] Finally, the pushing sleeve 7 is released, and the pushing sleeve 7 and the lifting cylinder 3 are reset under the action of the compression spring 720.

[0054] The above describes in detail the rotary clamp-type electronic smoking device provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art will be able to make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the claims of the present invention.
