Description

Technical Field

[0001] The present invention belongs to the technical field of smoking articles, and particularly relates to a cigarette magazine and a low-temperature smoking device. Background Art

[0002] Compared with traditional cigarettes, a heat-not-burn smoking device directly heats tobacco or nicotine products at a heating temperature between 220 - 250°C. After baking, the smoke gradually volatilizes, which can reduce the generation of harmful smoke components through the combustion and thermal degradation of tobacco in traditional cigarettes.

[0003] Heat-not-burn products can be divided into surround heating and central heating in terms of heating forms. There are already a large number of smoking devices based on these two heating technologies. Among them, smoking devices loaded with cigarette cartridges occupy one category. However, the common smoking devices on the market still have various problems, resulting in the inability to truly popularize low-temperature cigarettes. For example, Chinese Patent CN106108112A provides a cigarette magazine, a low-temperature smoking device atomizer, and a low-temperature smoking device. Its cigarette cartridge loading method and unloading structure design are complex. In addition, since the cigarette cartridge is integrated on the heat-not-burn appliance, it inevitably causes the entire appliance to have a relatively large size. Summary of the Invention

A heating cavity and a cartridge inlet channel are provided in the smoking device body and are in communication with each other. A heating device is provided in the heating cavity. The cartridge ejection channel of the cigarette magazine is in communication with the cartridge inlet channel on the smoking device body. After the cartridge is pushed into the heating cavity by the cartridge push rod, it contacts the heating device in the heating cavity.

[0014] Furthermore, the heating device is a porous heating element. Airflow passes through the porous heating element, is heated, enters the cartridge from the bottom of the cartridge, and then flows out from the mouthpiece at the top of the smoking device body.

[0015] Furthermore, the heating device is a porous heating element. Airflow is heated by the porous heating element and then enters the cartridge.

[0016] Furthermore, an air inlet channel communicating with the heating cavity is provided on the smoking device body, and an anti-scalding component is provided on the air inlet channel;

[0017] An air inlet hole is provided on the anti-scalding component, and a cooling cavity filled with a cooling medium is formed in the side wall of the air inlet hole.

[0018] Furthermore, a spring door assembly that can be opened and closed is provided at the entrance of the cartridge inlet channel. The spring door assembly includes a torsion spring, an upper door, and a lower door. The upper door and the lower door are respectively rotatably connected to the upper side wall and the lower side wall of the cartridge inlet channel through rotating shafts, and the torsion springs are connected between the upper door and the lower door and the smoking device body.

[0019] Furthermore, the heating cavity is adapted to the cartridge. A cartridge baffle is vertically provided at the connection between the heating cavity and the cartridge inlet channel. The cartridge baffle can be withdrawn from the cartridge inlet channel driven by the lower door and reset under the action of a reset element. After the cartridge baffle is reset, it abuts against the side of the cartridge.

[0020] Furthermore, an opening communicating with the heating chamber to facilitate dumping of the cigarette cartridge is provided on the top of the smoking device body, and the suction nozzle is detachably installed in the opening.

[0021] Furthermore, after the cigarette cartridge push rod pushes the cigarette cartridge into the heating chamber, the tail wing of the cigarette cartridge push rod presses the cigarette cartridge in the cigarette cartridge filling chamber.

[0022] Furthermore, a battery for supplying power to the heating device is disposed in the smoking device body.

[0023] Furthermore, a condenser is provided in the suction nozzle.

[0024] Compared with the prior art, the present invention has the advantages of:

[0025] 1. A cartridge push rod is provided in the cartridge magazine. After the cartridge enters the cartridge push channel under the pushing action of the cartridge push plate, the cartridge can be pushed out of the cartridge push channel by turning the cartridge push rod. The structure is simple and the operation is convenient.

[0026] 2. An anti-scalding structure is provided in the air inlet channel of the smoking device. When the heat-not-burn smoking device is blown backwards, the high-temperature smoke generated inside enters the air inlet through the large hole end of the air inlet, and then flows out from the small hole end. As the smoke flows from the large hole end to the small hole end, the smoke is squeezed and released from the small hole, a small throttling effect can be generated, which will cause the temperature near the small hole to drop, thereby achieving the effect of cooling the high-temperature smoke flowing out of the smoking device in the reverse direction, which can effectively prevent consumers from being scalded and improve the safety and convenience of use.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1 and Figure 2 A cigarette cartridge magazine, a cigarette cartridge filling chamber and a cigarette cartridge pushing channel 703 are provided in the magazine body, the bottom end wall of the cigarette cartridge pushing channel 703 is connected to the top end wall of the cigarette cartridge filling chamber, a cigarette cartridge pushing plate 3 is slidably provided in the cigarette cartridge filling chamber, a spring 2 is provided between the cigarette cartridge pushing plate 3 and the bottom of the cigarette cartridge filling chamber, and a cigarette cartridge pushing rod 8 is slidably provided in the cigarette cartridge pushing channel 703.

[0038] When the cigarette cartridge magazine is in use, the cigarette cartridge 4 enters the cigarette cartridge ejection channel 703 under the pushing action of the spring 2. At this time, the cigarette cartridge push rod 8 can be pushed out from the channel outlet end to push the cigarette cartridge 4 into the cigarette cartridge ejection channel 703. After the previous cigarette cartridge is pushed out, the cigarette cartridge push rod 8 is pushed in the opposite direction to reset it. The next cigarette cartridge in the cigarette cartridge filling chamber moves upward a distance of the cigarette cartridge height under the action of the spring to enter the cigarette cartridge ejection channel 703. This process can be repeated to push out all the cigarette cartridges in the cigarette cartridge filling chamber. The cigarette cartridge filling chamber is adapted to the cigarette cartridge 4, and its cross-section can be circular, square or other shapes.

[0039] See also Figure 1 and Figure 2 Specifically, the magazine body includes a base 1, a cigarette cartridge cover 5 and a magazine shell 7. A mounting cavity adapted to the cigarette cartridge cover 5 is formed in the magazine shell 7. The base 1 closes the bottom end of the cigarette cartridge cover 5. The spring 2 is connected to the base 1 and fixed on the base 1. The cigarette cartridge push plate 3 is directly connected to the spring 2.

[0040] In order to allow the base to be better embedded in the magazine and not fall off easily, a barb 101 structure is adopted. When the base 1 is inserted into the cigarette cartridge cover 5, the barb 101 falls into the groove 505 of the cigarette cartridge cover 5 and is stuck therein.

[0041] The base 1 is provided with a buckle 102. When the cigarette magazine 5 is inserted into the magazine shell 7 and rotated at a certain angle, the buckle 102 of the base 1 is inserted into the groove 704 of the magazine shell 7, thereby achieving the purpose of fixing the entire cigarette magazine.

[0042] See also Figure 1 and Figure 2, the cartridge sleeve 5 is used to load the cartridge 4, and its inner cavity forms a cartridge filling cavity. The cartridge ejection channel 703 is arranged in the magazine housing 7. A push plate guiding groove 502 is vertically provided on the side of the cartridge filling cavity. The cartridge push plate 3 is provided with a guiding rib 301. The guiding rib 301 is snapped into the push plate guiding groove 502 and extends outside the cartridge sleeve 5. The cartridge push plate 3 moves up and down along the push plate guiding groove 502 through the guiding rib 301. After using one cartridge, the cartridge push plate 3 moves upward by a distance equal to the thickness of one cartridge in the cartridge filling cavity under the action of the spring 2. When the user needs to replenish the cartridge 4, the cartridge can be loaded by sliding the cartridge push plate 3 downward to compress the spring.

[0043] See Figure 1 and Figure 2 , a transverse channel 503 directly communicating with the top end of the cartridge filling cavity is provided on the side of the cartridge sleeve 5. The transverse channel 503 is perpendicular to the cartridge filling cavity and the height of its cross-section is equal to the height of the cartridge 4, so as to ensure that exactly one cartridge is located in the transverse channel 503 waiting to be ejected before each push. At the same time, after the cartridge sleeve 5 is pulled out of the magazine housing 7, the cartridge will not be automatically ejected from the cartridge sleeve 5, solving the positioning problem of the cartridge in the cartridge sleeve 5.

[0044] In the cartridge magazine of this embodiment, when the cartridge sleeve 5 is inserted and fixed in the magazine housing 7, the transverse channel 503 is just located in the cartridge ejection channel 703 in the same direction and the bottoms of the two channels are flush. At this time, when the cartridge push rod is pushed, the cartridge push rod can eject the cartridge in the transverse channel through the cartridge ejection channel. When the previous cartridge is ejected and the cartridge push rod 8 exits the transverse channel, the next cartridge can be filled into the cartridge transverse channel 503 from the top of the cartridge filling cavity and loaded into the cartridge magazine, and is fixed in position under the action of the spring.

[0045] See Figure 2 , a push rod guiding groove parallel to the cartridge ejection channel 503 is provided at the top of the magazine housing 7. The top of the cartridge push rod 8 is provided with a lever 802 adapted to the push rod guiding groove. A groove 504 for the lever 802 to slide through and communicating with the transverse channel 503 is provided at the top of the cartridge sleeve 5. When the cartridge push rod 8 slides from one end of the cartridge ejection channel 503 through the transverse channel 503 to the other end, the lever 802 slides through the groove 504.

[0046] See Figure 2 , it should be explained that the housing 6 is used to surround the magazine housing 7; the magazine housing 7 is used to place the cartridge magazine. The magazine housing 7 is provided with a groove 704 that can limit the up and down movement of the barb 101. The magazine housing 7 is provided with two limiting grooves 701. When the cartridge magazine is inserted into the entire magazine housing 7, the limiting ribs 501 on the cartridge sleeve 5 fall into the limiting grooves 701. Through the cooperation of the limiting ribs 501 and the limiting grooves 701, the center line direction of the transverse channel 503 is kept consistent with the moving direction of the cartridge push rod 8.

[0047] The magazine housing 7 is provided with a guide rail 702, and the part of the guiding rib 301 extending out of the cartridge sleeve 5 is inserted into the guide rail 702. As the cartridges 4 are successively used, the cartridge push plate 3 slides upward as the cartridge 4 moves upward. At this time, the protruding guiding rib 301 on the cartridge push plate 3 can slide up and down within the guide rail 702.

[0048] See Figure 1 and Figure 2 , the cartridge 4 includes one or more quantities, which facilitates the user to draw the next cartridge after finishing drawing one cartridge; as a preferred solution, the periphery of the cartridge 4 is wrapped with a material having good thermal conductivity and high temperature resistance, and the parts of the wrapping material in contact with the upper and lower surfaces of the cartridge 4 are perforated to facilitate the airflow through the cartridge. The purpose of wrapping the cartridge is on the one hand to prevent gas from entering and exiting from both sides of the cartridge 4, and on the other hand to minimize the detachment of fragmented cartridge substances from the cartridge, polluting the channel, and even causing the phenomenon that the cartridge or components are stuck.

[0049] See Figure 3 , a low-temperature smoking device, includes a smoking device body. A smoking device bracket 10 is contained in the smoking device housing 9 of the smoking device body, which facilitates the positioning of internal components and maintains a certain structural neatness.

[0050] See Figure 3 , in the present invention, a heating chamber and a cartridge inlet passage are provided in the smoking device housing 9 and are in communication with each other. A heating element 11 is provided in the heating chamber. The cartridge ejection passage of the cartridge magazine is in communication with the cartridge inlet passage on the smoking device body. A mouthpiece 20 communicating with the heating chamber is further provided on the smoking device housing 9. After the cartridge 4 is sent into the heating chamber under the pushing of the cartridge push rod 8, it contacts the heating element 11 in the heating chamber. The heating element 11 heats the cartridge 4 to generate the smoke for the user to draw. The generated smoke enters the user's mouth through the mouthpiece 20, and the cartridge loading structure is very simple.

[0051] See Figure 3 and Figure 4 , a circuit board 23, a battery 24 and a switch 25 are further provided in the smoking device housing 9. The circuit board 23 is connected to the heating element 11 and controls the heating of the heating element 11; the circuit board 23 is directly connected to the battery 24; the circuit board 23 is provided with a switch 25 to control the switch of the smoking device.

[0052] See Figure 3Specifically, an opening is provided at the top of the smoking device shell 9 for convenient dumping of the cigarette cartridge, and the suction nozzle 20 is inserted and fixed in the opening. The suction nozzle 20 is made of high-temperature resistant environmentally friendly materials and adopts a straight-through hole design; the condenser 21 can be loaded inside the suction nozzle and can be replaced; the outside of the suction nozzle is wrapped with a sealing ring 22, and the sealing ring 22 material is a flexible and high-temperature resistant material to facilitate the insertion and removal of the suction nozzle 20. When it is necessary to dump the used cigarette cartridge, you only need to pull out the suction nozzle and pour the cigarette cartridge in the heating chamber out of the smoking device from the opening. The cigarette cartridge unloading structure is very simple.

[0053] See also Figure 3 and Figure 4 In addition, in order to prevent smoke from overflowing from the smoke cartridge entrance channel, an openable and closable spring door assembly is provided at the smoke cartridge entrance of the smoke cartridge entrance channel, and the spring door assembly comprises a torsion spring 14, an upper door 15 and a lower door 16, and the upper door 15 and the lower door 16 are rotatably connected to the upper side wall and the lower side wall of the smoke cartridge entrance channel respectively through a rotating shaft 13, and a torsion spring 15 is connected between the upper door 15 and the smoking device shell, and between the lower door 16 and the smoking device shell, and the rotating shaft 13 is directly fixed on the smoking device shell 9, and the torsion spring 14 is hung on the rotating shaft 13 and is in contact with the upper door 15 and the lower door 16.

[0054] The heating element 11 used in this embodiment adopts a porous structure; the upper surface of the heating element 11 is in direct contact with the lower surface of the cigarette cartridge 4, and provides heat to the cigarette cartridge by heat conduction; when the user heats the device for inhalation, the air flow passes through the porous heating element 11 and the gas is heated, and the heated high-temperature gas provides heat to the cigarette cartridge 4 in the form of forced convection.

[0055] To facilitate the withdrawal of the cigarette cartridge from the heating chamber, the top of the heating element 11 is flush with the bottom of the cigarette cartridge entry channel.

[0056] See also Figure 3 and Figure 4 In order to prevent heat from being transferred to the smoking device shell, a heat insulating component 12 is used to insulate the heating element 11, protect the device circuit board, and prevent excessive loss of heat generated by the heating element 11. The heat insulating component 12 can adopt heat insulating structures such as fire-resistant insulation cotton, vacuum tubes and aerogel.

[0057] See also Figure 3 and Figure 4 The side of the cigarette cartridge entry channel close to the heating chamber is designed with a cigarette cartridge baffle 17 to prevent the cigarette cartridge 4 from moving left and right and leaving the heating chamber during use. As a preferred solution, in order to prevent heat loss, the cigarette cartridge baffle 17 is made of a heat-insulating material that is resistant to high temperatures and has a heat-insulating function. The bottom of the cigarette cartridge baffle 17 is connected to the baffle spring 18. The smoking device housing 9 also needs to be designed with a toggle member that can drive the cigarette cartridge baffle 17 to move up and down. In this embodiment, the toggle member is the lower door 16.

[0058] See Figure 5 、 Figure 6 and Figure 7 For the loading process of the cartridge of the present smoking implement, the cartridge push rod moves from left to right, pushing the cartridge 4 out of the cartridge magazine. When the cartridge 4 touches the upper door 15 and the lower door 16, as the cartridge 4 continues to move to the right, the upper door 15 rotates counterclockwise around the rotating shaft 13, and the lower door 16 rotates clockwise around the rotating shaft 13; along the cartridge entry channel, the cartridge 4 is pushed into a position coaxial with the vertical axis of the heating element. As the lower door 16 continues to rotate clockwise, the lower door 16 will contact the cartridge baffle 17, and the baffle spring 18 is compressed under force, and the cartridge baffle 17 moves downward until the cartridge is pushed into the heating chamber; there is an extended part, the cartridge push rod tail fin 801, at the tail of the cartridge push rod 8. When the cartridge 4 is just pushed into the heating chamber, the cartridge push rod tail fin 801 abuts against the cartridge in the cartridge magazine, preventing the cartridge from moving upward; when the cartridge loading is completed, push the cartridge push rod 8 to move to the left. As the cartridge push rod moves away from the smoking implement, the upper door 15 and the lower door 16 rotate clockwise and counterclockwise respectively under the action of the torsion spring 14; as the lower door 16 rotates counterclockwise, the cartridge baffle 17 that was previously in contact with the lower door 16 and received its downward resistance force moves upward under the action of the baffle spring 18 and finally contacts the left side of the cartridge 4, which can prevent the cartridge 4 from shifting or even falling off when the smoking implement rotates to any angle; when the cartridge push rod 8 moves to disengage from the smoking implement, the upper door 15 and the lower door 16 are completely closed; when the cartridge push rod 8 continues to move to the left and the rightmost side of the cartridge push rod 8 is at the leftmost side of the cartridge magazine, the cartridge 4 is subjected to the force of the spring 2, and the cartridges in the entire cartridge magazine move upward by a distance equal to the thickness of one cartridge as a whole.

[0059] When the last cartridge is pushed out of the cartridge magazine and the cartridge push rod 8 completes the cartridge loading and retracts to the leftmost end of its stroke, the cartridge push plate 3 is pushed to the maximum stroke of the push plate guide groove under the action of the spring 2 and cannot continue to move upward. At this time, the upper surface of the cartridge push plate 3 is on the same plane as the lower surface of the transverse channel 503.

[0060] See Figure 8 and Figure 9 After the smoking implement completes the cartridge loading, the smoking implement body can be separated from the cartridge magazine, and the user can take out the smoking implement with the cartridge alone for use, which allows the user to have a smoking experience with a smaller size. The smoking implement body and the cartridge magazine can be assembled in a detachable manner such as magnetic adsorption or snap connection.

[0061] When the cartridge is exhausted, the user manually removes the mouthpiece 20 from the smoking implement and pours out the cartridge 4 from the smoking implement in an inverted manner.

[0062] See Figure 3 andFigure 4 It can be understood that, as a preferred embodiment of the low-temperature smoking device of the present invention, a heat-insulating component 19 is provided at the inlet end of the air intake passage. An air intake hole is formed in the heat-insulating component 19, and a cooling cavity filled with a cooling medium is formed in the side wall of the air intake hole. On the one hand, the gas during suction enters the device through the heat-insulating component. On the other hand, when the gas flows out of the device in the reverse direction during the working state of the device, when the high-temperature gas flows through the heat-insulating component, the component will have a good cooling effect on the high-temperature air flow, reducing the temperature of the smoke to a safe range and playing a role in protecting the user.

[0063] The air flow direction of this embodiment is as follows: External air enters the smoking device from the heat-insulating component, then successively passes through the contacting heating element 11 and the cartridge 4, then enters the condenser 21, and then enters the user's mouth through the air intake hole of the mouthpiece 20 and is inhaled by the user.

[0064] An air intake hole with a cross-section gradually decreasing from the inside of the smoking device body to the outside of the smoking device body is formed in the heat-insulating component, and a cooling cavity for filling a cooling medium is formed in the side wall of the air intake hole.

[0065] In this embodiment, a heat-insulating structure is provided in the air intake of the smoking device. When the heat-not-burn smoking device is blown in the reverse direction, the high-temperature smoke generated inside enters the air intake hole from the large-hole end of the air intake hole and then flows out from the small-hole end. Since the smoke is squeezed and released from the small hole during the process of flowing from the large-hole end to the small-hole end, a small throttling effect can be generated, which will cause the temperature near the small hole to decrease, so as to achieve the purpose of cooling the high-temperature smoke flowing out in the reverse direction, and can effectively prevent consumers from being scalded and improve the safety and convenience of use.

[0066] The above embodiments are merely examples clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
