Description

Technical Field

[0001] The present invention belongs to the technical field of electronic cigarette devices, and particularly relates to a heating device for non-combustible cigarettes by heating. Background Art

[0002] Traditional cigarettes need to be ignited by an open flame and then burned to produce tobacco smoke. During the process of high temperature and pyrolysis of tobacco, thousands of harmful substances to the human body are released, which are composed of volatiles in gas, semi-volatiles and non-volatiles in particles, such as carbon monoxide, phenols, aldehydes, nicotine (nicotinic), tar, etc. While non-combustible cigarette heating devices can effectively reduce the generation of harmful substances and are healthier.

[0003] During the process of sucking low-temperature non-combustible cigarettes, an external heating device - that is, a non-combustible cigarette heating device - needs to be used.

[0004] Chinese Patent (Publication No.: CN107890141A) discloses a non-combustible cigarette heating device with an extractor, which is characterized in that it includes a rotating outer shell, an extractor and a heating device provided with a heating cavity; the extractor has a relative first end and a second end, the first end is installed in the heating cavity of the heating device, the second end is provided with an insertion cavity for inserting a smoking article, and a spiral guide groove is arranged on the outer peripheral wall of the second end; the rotating outer shell is hollow, one end is sleeved on the heating device, and the other end is provided with a clamping component that slidably cooperates with the spiral guide groove; a strip-shaped guide rail is arranged on the inner wall of the heating cavity along the direction from its bottom to its cavity opening; a strip-shaped guide groove that slidably cooperates with the strip-shaped guide rail is arranged on the outer peripheral wall of the first end, so as to screw the extractor into / out of the heating cavity. It uses the rotation of the extractor relative to the heating sheet to drive the cigarette to rotate out of the heating sheet, avoiding the problem that the tobacco end of the smoking article after smoking is easily adhered to the heating cavity of the non-combustible electronic cigarette device and is not easy to pull out.

[0005] In the actual use process of the above patent, although the problem that the tobacco end of the smoking article is easily adhered to the heating cavity of the non-combustible electronic cigarette device and is not easy to pull out is solved, however, since the extractor does not clamp the smoking cigarette during the smoking process, when the user's lips are dry during the smoking process, the user's lips are easily adhered to the cigarette, resulting in the problem that the cigarette is pulled out of the smoking device during smoking. Summary of the Invention

[0006] The purpose of the present invention is to provide a heating device for non-combustible cigarettes by heating, which is used to solve the problem that when the user's lips are dry during the smoking process, the user's lips are easily adhered to the cigarette, resulting in the cigarette being pulled out of the heating device during smoking due to the structural defects of the existing heating device.

[0007] To achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0008] A heating device for heat-not-burn cigarettes includes a main body, a heating mechanism, and a rotating 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 rotating cylinder passes through the connecting cylinder and is sleeved on the heating mechanism. An annular support platform sleeved on the heating rod is integrally formed on the inner wall of the rotating cylinder above the heating mechanism. A spiral spring is installed between the main body and the rotating cylinder and is located between the heating mechanism and the connecting cylinder. An annular positioning groove is formed on the outer wall of the rotating cylinder. A limiting block is fixedly installed on the inner wall of the connecting cylinder and is located in the annular positioning groove. An installation ring is fixedly provided above the connecting cylinder on the rotating cylinder. A push rod is fixedly provided on the installation ring on the outer wall of the connecting cylinder. Two hinge columns are fixedly installed on the installation ring. An arc-shaped clamping block is hinged to the installation ring through the hinge columns. An arc-shaped groove is formed in the arc-shaped clamping block. The arc-shaped groove gradually deflects outward from one end close to the hinge column to the end far from the hinge column. A semi-ring is installed above the arc-shaped clamping block on the main body. Two fixing frames are fixedly installed on the semi-ring. A sliding column is installed on the lower end surface of the free end of the fixing frame. The sliding column is located in the arc-shaped groove.

[0009] Further defined, the depth dimension of the arc-shaped groove is smaller than the thickness dimension of the arc-shaped clamping block. With such a structural design, the arc-shaped groove does not penetrate the lower end surface of the arc-shaped clamping block, which can prevent the sliding column from contacting the installation ring.

[0010] Further defined, a bearing is rotatably installed on the sliding column, and the outer diameter dimension of the bearing is smaller than the width dimension of the arc-shaped groove. With such a structural design, when driving the arc-shaped clamping block to deflect through the sliding column, the bearing is used to replace the sliding column to contact the arc-shaped clamping block, converting the sliding friction between the sliding column and the arc-shaped clamping block into the rolling friction between the bearing and the arc-shaped clamping block, thereby reducing the frictional force, making the pushing of the push rod smoother, and at the same time reducing the wear of the side wall of the arc-shaped groove of the arc-shaped clamping block and prolonging the service life of the arc-shaped clamping block.

[0011] Further defined, the arc-shaped groove is composed of a first arc-shaped groove and a second arc-shaped groove that communicate with each other. The inner end faces of the arc-shaped clamping block, the first arc-shaped groove, and the second arc-shaped groove are all arc-shaped. The center of the arc of the inner side surface of the arc-shaped clamping block coincides with the center of the arc of the inner side surface of the second arc-shaped groove. The first arc-shaped groove gradually deflects outward from the end close to the hinge column to the end far from the hinge column. With such a structural design, when the sliding column slides in the first arc-shaped groove, the sliding column pushes the free end of the arc-shaped clamping block to move inward or outward. When the sliding column slides into the second arc-shaped groove, since the center of the arc of the inner side surface of the arc-shaped clamping block coincides with the center of the arc of the inner side surface of the second arc-shaped groove, at this time, the arc-shaped clamping block can be held in this position and will not continue to move inward, avoiding excessive clamping of the cigarette.

[0012] Further defined, the cross-section of the limit block is T-shaped, and a T-shaped installation groove is formed on the outer wall of the connecting cylinder. The limit block is installed in the T-shaped installation groove, and the inner end is located in the annular positioning groove. With such a structural design, the structure is simple and the installation is convenient.

[0013] Further defined, a stop post is integrally formed on the connecting cylinder, and a stop block is integrally formed on each side of the stop post on the outer side of the mounting ring. With such a structural design, through the mutual cooperation of the two stop blocks and the stop post, the rotation angle of the rotating cylinder is limited, which can avoid excessive twisting of the rotating cylinder under the action of the coil spring and can also avoid excessive twisting of the rotating cylinder by the user during use, and the practicability is strong.

[0014] Further defined, the half ring is detachably installed on the stop post. With such a structural design, the half ring is connected to the main body by being detachably installed on the stop post. During the overall installation, the rotating cylinder can be installed in the connecting cylinder first, and then the half ring can be installed, which is more convenient for installation.

[0015] Further defined, the cross-section of the main body is oval, and a plurality of grooves are also formed on the outer wall of the main body. With such a structural design, the mutual cooperation of the main body with an oval cross-section and the grooves is more convenient for the user to hold.

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

[0017] 1. The cigarette in the smoking state is clamped by the arc-shaped clamping block, avoiding the problem that when the user's lips are dry during the user's smoking process, the user's lips are easily adhered to the cigarette and the cigarette is pulled out of the heating device during smoking;

[0018] 2. Through the mutual cooperation of the rotating cylinder, the arc-shaped clamping block and the arc-shaped groove, before pushing the push rod to drive the arc-shaped clamping block to release the clamping of the cigarette, the cigarette is first driven to rotate relative to the heating rod, and the friction between the cigarette and the heating rod is utilized to make the tobacco adhered to the heating rod fall off;

[0019] 3. Through the mutual cooperation of the arc-shaped clamping block and the arc-shaped groove, after the push rod is pushed to a certain angle, the sliding column drives the arc-shaped clamping block to rotate counterclockwise around the hinge column, so that the middle parts of the mounting ring and the rotating cylinder are completely exposed, facilitating the insertion of the cigarette, and at the same time releasing the clamping of the cigarette, facilitating the extraction of the cigarette.

[0037] 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 description of the drawings or the specification, similar or identical parts are all denoted by the same reference numerals, and 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, a heating device for a non-combustible cigarette of the present invention includes a main body 1, a heating mechanism 2 and a rotating 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 located inside the connecting cylinder 11. A heating rod 21 is fixedly installed on the heating mechanism 2. The rotating 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 rotating cylinder 3 above the heating mechanism 2. A coil spring 4 is installed between the main body 1 and the rotating cylinder 3. The coil spring 4 is located between the heating mechanism 2 and the connecting cylinder 11. An annular positioning groove 320 is formed on the outer wall of the rotating cylinder 3. A limiting block 32 is fixedly installed on the inner wall of the connecting cylinder 11. The limiting block 32 is located inside the annular positioning groove 320. The rotating cylinder 3 is fixedly provided with a mounting ring 8 above the connecting cylinder 11. A pushing rod 7 is fixedly provided on the mounting ring 8 on the outer wall of the connecting cylinder 11. Two hinged columns 81 are fixedly installed on the mounting ring 8. The mounting ring 8 is hinged with an arc-shaped clamping block 5 through the hinged columns 81. An arc-shaped groove 50 is formed on the arc-shaped clamping block 5. The arc-shaped groove 50 gradually deflects outward from the end close to the hinged column 81 to the end far from the hinged column 81. A half ring 9 is installed on the main body 1 above the arc-shaped clamping block 5. Two fixing brackets 91 are fixedly installed on the half ring 9. A sliding column 92 is installed on the lower end surface of the free end of the fixing bracket 91. The sliding column 92 is located inside the arc-shaped groove 50.

[0039] The depth dimension of the arc-shaped groove 50 is smaller than the thickness dimension of the arc-shaped clamping block 5. The arc-shaped groove 50 does not penetrate the lower end surface of the arc-shaped clamping block 5, which can prevent the sliding column 92 from contacting the mounting ring 8.

[0040] A bearing is rotatably installed on the sliding column 92, and the outer diameter of the bearing is smaller than the width of the arc-shaped groove 50. When driving the arc-shaped clamping block 5 to deflect through the sliding column 92, the bearing is used to contact the arc-shaped clamping block 5 instead of the sliding column 92, converting the sliding friction between the sliding column 92 and the arc-shaped clamping block 5 into the rolling friction between the bearing and the arc-shaped clamping block 5, thereby reducing the frictional force, making the pushing of the push rod 7 smoother, and at the same time reducing the wear on the side wall of the arc-shaped groove 50 of the arc-shaped clamping block 5 and extending the service life of the arc-shaped clamping block 5.

[0041] The arc-shaped groove 50 is composed of a first arc-shaped groove 501 and a second arc-shaped groove 502 that are interconnected. The inner end faces of the arc-shaped clamping block 5, the first arc-shaped groove 501, and the second arc-shaped groove 502 are all arc-shaped. The center of the arc on the inner side of the arc-shaped clamping block 5 coincides with the center of the arc on the inner side of the second arc-shaped groove 502. The first arc-shaped groove 501 gradually deflects outward from the end close to the hinge column 81 to the end far from the hinge column 81. When the sliding column 92 slides in the first arc-shaped groove 501, the sliding column 92 pushes the free end of the arc-shaped clamping block 5 to move inward or outward. When the sliding column 92 slides into the second arc-shaped groove 502, since the center of the arc on the inner side of the arc-shaped clamping block 5 coincides with the center of the arc on the inner side of the second arc-shaped groove 502, at this time, the arc-shaped clamping block 5 can be held in this position and will not continue to move inward, avoiding excessive clamping of the cigarette.

[0042] The cross-section of the limit block 32 is T-shaped, and a T-shaped installation groove 110 is formed on the outer wall of the connecting cylinder 11. The limit block 32 is installed in the T-shaped installation groove 110, and the inner end is located in the annular positioning groove 320. The structure is simple and the installation is convenient.

[0043] A stop post 6 is integrally formed on the connecting cylinder 11, and a stop block 61 is integrally formed on each side of the stop post 6 on the outer side of the mounting ring 8. Through the mutual cooperation of the two stop blocks 61 and the stop post 6, the rotation angle of the rotating cylinder 3 is limited, which can avoid excessive distortion of the rotating cylinder 3 under the action of the coil spring 4 and can also avoid excessive distortion of the rotating cylinder 3 by the user during use, with strong practicability.

[0044] The semi-ring 9 is detachably installed on the stop post 6. The semi-ring 9 is connected to the main body 1 by being detachably installed on the stop post 6. During the overall installation, the rotating cylinder 3 can be first installed in the connecting cylinder 11, and then the semi-ring 9 can be installed, which is more convenient for installation.

[0045] The cross-section of the main body 1 is oval, and a plurality of grooves 10 are also formed on the outer wall of the main body 1. The mutual cooperation of the main body 1 with an oval cross-section and the grooves 10 is more convenient for the user to hold.

[0046] In this embodiment, when in use, hold the main body 1 by hand and push the push rod 7 with the thumb to drive the rotating cylinder 3 to rotate clockwise against the prestress of the coil spring 4;

[0047] During this process, utilize the relative rotation between the mounting ring 8 and the half ring 9, that is, the mounting ring 8 rotates clockwise relative to the half ring 9, causing the sliding column 92 to slide within the second arc-shaped groove 502. Since the center of the arc on the inner side of the arc-shaped clamping block 5 coincides with the center of the arc on the inner side of the second arc-shaped groove 502, at this time, the arc-shaped clamping block 5 can be maintained in this position and the arc-shaped clamping block 5 does not move until the sliding column 92 enters the first arc-shaped groove 501 from the second arc-shaped groove 502. By pushing the outer wall of the first arc-shaped groove 501 of the arc-shaped clamping block 5 through the sliding column 92, the arc-shaped clamping block 5 is caused to open outward, thereby exposing the hole between the mounting ring 8 and the rotating cylinder 3. Then, insert a cigarette into the rotating cylinder 3, make the cigarette abut against the annular support platform 31, and then release the push on the push rod 7;

[0048] After releasing the push rod 7, the rotating cylinder 3 rotates counterclockwise relative to the half ring 9 under the action of the coil spring 4. Furthermore, utilize the cooperation between the sliding column 92 and the first arc-shaped groove 501 to push the inner wall of the first arc-shaped groove 501 of the arc-shaped clamping block 5 through the sliding column 92, thereby causing the free end of the arc-shaped clamping block 5 to move inward, and further clamping the cigarette inserted into the rotating cylinder 3 until the sliding column 92 slides into the second arc-shaped groove 502. Since the center of the arc on the inner side of the arc-shaped clamping block 5 coincides with the center of the arc on the inner side of the second arc-shaped groove 502, at this time, the arc-shaped clamping block 5 can be maintained in this position and the arc-shaped clamping block 5 does not move,

[0049] The rotating cylinder 3 continues to rotate counterclockwise relative to the half ring 9 under the action of the coil spring 4, and further drives the cigarette clamped by the arc-shaped clamping block 5 to spiral downwards, so that the cigarette is sleeved on the heating rod 21;

[0050] After the suction is completed, the user holds the heating device and pushes the push rod 7 again, thereby driving the cigarette fixed by the arc-shaped clamping block 5 in the rotating cylinder 3 to rotate clockwise relative to the heating rod 21. Utilize the friction between the cigarette and the heating rod 21 to make the tobacco adhered to the heating rod 21 fall off until the sliding column 92 disengages from the second arc-shaped groove 502 and enters the first arc-shaped groove 501, driving the free end of the arc-shaped clamping block 5 to open outward and releasing the clamping of the cigarette. At this time, the cigarette in the rotating cylinder 3 can be taken out;

[0051] Finally, release the push rod 7, and the push rod 7 and the rotating cylinder 3 are reset under the action of the coil spring 4.

[0052] The above has introduced in detail a heating device for heat-not-burn cigarettes provided by the present invention. The description of specific embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
