Description

Technical Field

[0001] The present invention belongs to the technical field of electronic cigarette devices, and particularly relates to an electronic cigarette device capable of clamping a cigarette stick. Background Art

[0002] The heat-not-burn electronic cigarette device is a low-temperature flue-cured tobacco electronic cigarette device, which uses a temperature lower than the ignition point of tobacco to heat and bake the cigarette stick to achieve the purpose of smoking. When using this heat-not-burn electronic cigarette device to smoke cigarettes, the harmful components released are much less than those released when smoking cigarettes by the traditional method of lighting and sucking, and no soot is generated, which is more environmentally friendly.

[0003] The existing electronic cigarette device heats the cigarette stick by electric heating, that is, the electronic cigarette device has a heating cavity for accommodating the cigarette stick, and a heating rod is arranged in the heating cavity. By inserting the cigarette stick into the heating cavity of the electronic cigarette device and inserting the heating rod into the center of the cigarette stick, the heating circuit of the heating rod is started to generate heat to heat the cigarette stick, so that the cigarette stick generates smoke for the user to smoke.

[0004] However, when heating the cigarette stick with an electronic cigarette device with such a structure, after smoking is completed and the cigarette stick is removed from the electronic cigarette device, the tobacco in the cigarette stick often adheres to the heating rod. As a result, it is necessary to open the lid of the electronic cigarette device to clean the heating rod before the next cigarette can be used. Summary of the Invention

[0005] The purpose of the present invention is to provide an electronic cigarette device capable of clamping a cigarette stick, which is used to solve the problem that when the cigarette stick is removed from the existing electronic cigarette device due to its structural defect, the tobacco in the cigarette stick often adheres to the heating rod, so that it is necessary to open the lid of the electronic cigarette device to clean the heating rod before the next cigarette can be used.

[0006] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0007] An electronic cigarette device capable of clamping a cigarette, comprising a main body, a heating mechanism and a lifting cylinder. A connecting cylinder is fixedly connected to the main body. The heating mechanism is installed on the main body and located inside the connecting cylinder. A heating rod is fixedly installed on the heating mechanism. The lifting cylinder is inserted into 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. Vertical sliding grooves and spiral sliding grooves are formed on the inner wall of the connecting cylinder. The lower end of the vertical sliding groove communicates with the top end of the spiral sliding groove. The depth dimension of the vertical sliding groove decreases successively from top to bottom. The depth dimension of the spiral sliding groove is equal to the depth dimension of the lower end of the vertical sliding groove. A first stepped hole is radially formed in the outer wall of the lifting cylinder above the annular support platform. A clamping column is slidably installed in the first stepped hole. The inner end of the clamping column is located inside the inner side wall of the lifting cylinder. The outer end of the clamping column is clamped at the lower end of the spiral sliding groove. A first compression spring is installed in the first stepped hole and sleeved on the clamping column. A bearing is installed above the connecting cylinder at the upper end of the lifting cylinder. A pushing sleeve is slidably installed on the connecting cylinder. A connecting seat is fixedly provided above the connecting cylinder on the pushing sleeve. The connecting seat is fixedly connected to the outer ring of the bearing.

[0008] Further defined, a limiting groove is axially formed on the outer wall of the clamping column. A limiting block is axially provided on the inner wall of the first stepped hole of the lifting cylinder. The limiting block is clamped in the limiting groove. With such a structural design, through the mutual matching of the limiting groove and the limiting block, it is possible to avoid the clamping column from rotating during the sliding process in the vertical sliding groove and the spiral sliding groove, thereby causing distortion to the first compression spring and further affecting the elasticity of the first compression spring.

[0009] Further defined, an annular boss is integrally formed on the outer wall of the clamping column. The first compression spring is located inside the annular boss. A threaded column is also screwed in the first stepped hole. A second stepped hole is axially formed in the threaded column. The clamping column, the annular boss and the first compression spring are all located in the second stepped hole. A vertical groove is also formed on the outer end face of the threaded column. With such a structural design, the clamping column is restricted in the first stepped hole by the threaded column, with a simple structure, convenient manufacturing and installation, and strong practicability.

[0010] Further defined, the bearing is a two-way thrust angular contact ball bearing. With such a structural design, compared with a common deep groove ball bearing, the two-way thrust angular contact ball bearing can bear a greater axial thrust and is more suitable for this application.

[0011] Further limitation: a positioning groove is formed on the outer wall of the pushing sleeve, a stop block is installed on the outer wall of the connecting cylinder at the upper end of the positioning groove, a through hole is formed in the stop block, a guiding rod is also installed in the pushing sleeve within the positioning groove, the guiding rod passes through the through hole, a second compression spring is sleeved on the guiding rod within the positioning groove, and the second compression spring is located below the stop block. With such a structural design, after pushing the pushing sleeve upward to drive the lifting cylinder to move upward and then releasing the pushing sleeve, the pushing sleeve can move downward under the action of the second compression spring, thereby driving the lifting cylinder to descend and reset, facilitating the next use.

[0012] Further limitation: a positioning hole is formed at the top of the positioning groove of the pushing sleeve, the upper end of the guiding rod passes through the positioning hole, a through hole is formed at the bottom of the positioning groove of the pushing sleeve, a threaded blind hole is also formed at the lower end of the pushing sleeve, the threaded blind hole is coaxial with and communicates with the through hole, and a bolt is screwed in the threaded blind hole. With such a structural design, when installing the guiding rod and the second compression spring, the second compression spring can be first placed in the positioning groove, and then the guiding rod is inserted through the threaded blind hole so that the guiding rod passes through the second compression spring, the top end of the guiding rod passes through the positioning hole, and finally the bolt is screwed in the threaded blind hole to complete the installation of the guiding rod, which is convenient for installation.

[0013] Further limitation: a notch is formed at the lower part on the side of the pushing sleeve away from the positioning groove. With such a structural design, the lower side wall of the connecting cylinder on the side away from the positioning groove is exposed through the notch. During use, after holding the main body by hand, the index finger and middle finger can be placed on the connecting cylinder exposed by the notch, and then the pushing sleeve is pushed with the thumb, making it more convenient to use.

[0014] Further limitation: anti-slip threads are formed on the outer wall of the pushing sleeve. With such a structural design, the friction coefficient between the pushing sleeve and the finger is increased through the anti-slip threads, making it more convenient to push.

[0015] The invention adopting the above technical solution has the following advantages:

[0016] 1. Through the mutual cooperation of the lifting cylinder, the clamping post, the bearing, the vertical sliding groove, the spiral sliding groove, the first compression spring and the second compression spring, the lifting cylinder rotates while rising, thereby driving the cigarette stick fixed by the clamping post in the lifting cylinder to rotate relative to the heating rod. By using the friction between the cigarette stick and the heating rod, the tobacco adhered to the heating rod falls off;

[0017] 2. Through the mutual cooperation of the clamping post and the upper-deep and lower-shallow vertical sliding groove, the cigarette stick is not blocked by the clamping post when it is first inserted into the lifting cylinder, and the placement process is smoother;

[0018] 3. Through the mutual cooperation of the clamping post and the spiral sliding groove, when the clamping post is located in the spiral sliding groove, the cigarette stick is clamped;

[0019] 4. By the mutual cooperation of the lifting cylinder, the clamping post, the vertical sliding groove and the first compression spring, when the lifting cylinder is driven to descend by the second compression spring, the clamping post moves inwards against the prestress of the first compression spring to clamp the cigarette.

[0020] 5. The lifting cylinder and the pushing sleeve are connected by bearings, and by the mutual matching of the stop block and the positioning groove, it can be avoided that the pushing sleeve is driven to rotate when the lifting cylinder rotates. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the description of the drawings or the specification, similar or identical parts are all denoted by the same reference numerals. The implementation manners not shown or described in the drawings are the forms known to those of ordinary skill in the art. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "rear", etc., are only references to the directions of the drawings and are not used to limit the protection scope of the present invention.

[0038] As Figures 1 to 6 shown, an electronic cigarette device capable of clamping cigarette sticks of the present invention includes a main body 1, a heating mechanism 2 and a lifting cylinder 3. A connecting cylinder 11 is fixedly connected to the main body 1. The heating mechanism 2 is installed on the main body 1 and is located inside the connecting cylinder 11. The heating mechanism of this technical solution is the same as the commonly used heating mechanism at present. A heating rod 21 is fixedly installed on the heating mechanism 2. The lifting cylinder 3 is inserted into the connecting cylinder 11 and sleeved on the heating mechanism 2. 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.

[0039] A vertical sliding groove 41 and a spiral sliding groove 42 are formed on the inner wall of the connecting cylinder 11. The lower end of the vertical sliding groove 41 communicates with the upper end of the spiral sliding groove 42. The depth dimension of the vertical sliding groove 41 decreases successively from top to bottom. The depth dimension of the spiral sliding groove 42 is equal to the depth dimension of the lower end of the vertical sliding groove 41. A first stepped hole is radially formed above the annular support platform 31 on the outer wall of the lifting cylinder 3. A clamping column 5 is slidably installed in the first stepped hole. The inner end of the clamping column 5 is located inside the inner side wall of the lifting cylinder 3. The outer end of the clamping column 5 is clamped at the lower end of the spiral sliding groove 42. A first compression spring 51 is installed in the first stepped hole. The first compression spring 51 is sleeved on the clamping column 5. A bearing 6 is installed above the connecting cylinder 11 at the upper end of the lifting cylinder 3. A push sleeve 7 is slidably installed on the connecting cylinder 11. A connecting seat 70 is fixedly provided on the push sleeve 7 above the connecting cylinder 11. The connecting seat 70 is fixedly connected to the outer ring of the bearing 6.

[0040] A limiting groove 502 is axially formed on the outer wall of the clamping column 5. A limiting block is axially provided on the inner wall of the first stepped hole of the lifting cylinder 3. The limiting block is clamped in the limiting groove 502. Through the mutual matching of the limiting groove 502 and the limiting block, it is possible to prevent the clamping column 5 from rotating during the sliding process in the vertical sliding groove 41 and the spiral sliding groove 42, thereby causing distortion to the first compression spring 51 and further affecting the elasticity of the first compression spring 51.

[0041] An annular boss 503 is integrally formed on the outer wall of the clamping post 5. The first compression spring 51 is located inside the annular boss 503. A threaded post 52 is also screwed in the first stepped hole. A second stepped hole 520 is axially formed in the threaded post 52. The clamping post 5, the annular boss 503 and the first compression spring 51 are all located in the second stepped hole 520. A vertical groove 521 is also formed on the outer end face of the threaded post 52. Restricting the clamping post 5 in the first stepped hole through the threaded post 52 has a simple structure, is convenient for manufacturing and installation, and has strong practicability.

[0042] The bearing 6 is a double-direction thrust angular contact ball bearing. Compared with a common deep groove ball bearing, the double-direction thrust angular contact ball bearing can bear a greater axial thrust and is more suitable for this application.

[0043] Positioning grooves 71 are formed on the outer wall of the push sleeve 7. A stop block 110 is installed on the outer wall of the connecting cylinder 11 at the upper end of the positioning groove 71. Through holes are formed in the stop block 110. A guide rod 72 is also installed in the push sleeve 7 in the positioning groove 71. The guide rod 72 is inserted through the through hole. A second compression spring 720 is sleeved on the guide rod 72 in the positioning groove 71. The second compression spring 720 is located below the stop block 110. After pushing the push sleeve 7 upward to drive the lifting cylinder 3 to move upward, when the push sleeve 7 is released, the push sleeve 7 can move downward under the action of the second compression spring 720, thereby driving the lifting cylinder 3 to descend and reset, which is convenient for the next use.

[0044] The push sleeve 7 is provided with a positioning hole at the top of the positioning groove 71. The upper end of the guide rod 72 is inserted through the positioning hole. A through hole is formed at the bottom of the positioning groove 71 of the push sleeve 7. A threaded blind hole is also formed at the lower end of the push sleeve 7. The threaded blind hole is coaxial with and communicates with the through hole. A bolt is screwed in the threaded blind hole. When installing the guide rod 72 and the second compression spring 720, the second compression spring 720 can be first placed in the positioning groove 71, and then the guide rod 72 is inserted through the threaded blind hole, so that the guide rod 72 is inserted through the second compression spring 720, the top end of the guide rod 72 is inserted through the positioning hole, and finally the bolt is screwed in the threaded blind hole, then the installation of the guide rod 72 can be completed, and the installation is convenient.

[0045] A notch 701 is formed at the lower part on the side of the push sleeve 7 away from the positioning groove 71. The lower side wall of the side of the connecting cylinder 11 away from the positioning groove 71 is exposed through the notch 701. When in use, after holding the main body 1 by hand, the index finger and the middle finger can be placed on the connecting cylinder 11 exposed by the notch 701, and then the push sleeve 7 is pushed by the thumb, which is more convenient to use.

[0046] Anti-slip lines are formed on the outer wall of the push sleeve 7. The friction coefficient between the push sleeve 7 and the fingers is increased through the anti-slip lines, and the pushing is more convenient.

[0047] In this embodiment, when in use, hold the main body 1 by hand, place the index finger and middle finger on the connecting cylinder 11 exposed by the notch 701, and then push the push sleeve 7 upward with the thumb. Through the mutual cooperation of the clamping post 5 and the spiral sliding groove 42, the lifting cylinder 3 spirally ascends in the connecting cylinder 11 until the clamping post 5 enters the vertical sliding groove 41 from the spiral sliding groove 42. Continue to push, and the lifting cylinder 3 linearly ascends. During this process, since the depth dimension of the vertical sliding groove 41 decreases sequentially from top to bottom, the clamping post 5 moves outward under the action of the first compression spring 51 until the clamping post 5 abuts against the top end of the vertical sliding groove 41. At this time, insert a cigarette into the lifting cylinder 3 so that the cigarette abuts against the annular support platform 31, and then release the push on the push sleeve 7;

[0048] At this time, the push sleeve 7 moves downward under the action of the second compression spring 720, and then drives the lifting cylinder 3 to move downward through the bearing 6. During this process, as the lifting cylinder 3 descends, the clamping post 5 gradually moves inward under the action of the vertical sliding groove 41 with the depth dimension decreasing sequentially from top to bottom to clamp the cigarette until the outer end of the clamping post 5 enters the spiral sliding groove 42;

[0049] After the outer end of the clamping post 5 enters the spiral sliding groove 42, the lifting cylinder 3 spirally descends along the spiral sliding groove 42 under the mutual action of the clamping post 5 and the spiral sliding groove 42, thereby driving the cigarette clamped by the clamping post 5 to spiral downward, so that the cigarette is sleeved on the heating rod 21;

[0050] After smoking is completed, the user holds the electronic cigarette device by hand and pushes the push sleeve 7 upward again. The cigarette is driven to spiral upward through the lifting cylinder 3, and then the cigarette fixed by the clamping post 5 in the lifting cylinder 3 rotates relative to the heating rod 21. By using the friction between the cigarette and the heating rod 21, the tobacco adhered to the heating rod 21 falls off until the clamping post 5 enters the vertical sliding groove 41. Continue to push to the top, and the clamping post 5 releases the clamping of the cigarette. At this time, the cigarette in the lifting cylinder 3 can be taken out;

[0051] Finally, release the push sleeve 7, and the push sleeve 7 and the lifting cylinder 3 are reset under the action of the second compression spring 720.

[0052] The above has introduced in detail an electronic cigarette device capable of clamping cigarettes provided by the present invention. The description of the specific embodiments is only used to help understand the method and its core idea of the present invention.
