Description

Technical Field

[0001] This utility model relates to the field of cigarette lighter technology, specifically to an automatic cigarette lighter mechanism for simulating human smoking. Background Technology

[0002] With the rapid development of my country's national economy, the country is paying increasing attention to individual physical and mental health. In the production of various equipment requiring real smoke testing, such as fire alarm systems and medical research, there is a significant need for simulated human smoking tests. Therefore, the demand for harmless simulated human smoking devices is also growing.

[0003] In existing technologies, in simulated human smoking test scenarios, the lighting and replacement of cigarettes are usually done manually. Testers need to manually place the cigarette stick in a designated position, light it with a lighter or other ignition device, and manually replace it with the next cigarette stick after one cigarette stick has burned out to continue the test.

[0004] However, the above-mentioned manual operations are not only inefficient and cannot meet the needs of a large number of continuous tests, but also cause testers to become fatigued during the long-term repetitive process of lighting and changing cigarettes, leading to an increase in the rate of operational errors. At the same time, frequent manual operations also increase labor costs.

[0005] In light of this, we have launched an automatic cigarette lighter mechanism that simulates human smoking. Utility Model Content

[0006] The purpose of this invention is to provide an automatic cigarette-lighting mechanism for simulating human smoking, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic cigarette lighting mechanism for simulating human smoking, comprising: a housing, wherein an L-shaped bracket is provided on the inner side of the housing, and a guide rail block for limiting the position is provided on the inner side of the L-shaped bracket;

[0008] L-shaped heating rod support base, the L-shaped heating rod support base is set on the side of the box body, and the side of the L-shaped heating rod support base is connected with bolts;

[0009] A heating rod is disposed on the surface of an L-shaped heating rod support base, and the heating rod is used to ignite the cigarette strip by generating heat.

[0010] The surface of the L-shaped bracket is provided with a driving mechanism. The moving block of the driving mechanism and the heating rod limit switch work together to control the heating rod body to heat up.

[0011] Preferably, the driving mechanism includes a motor A connected to the side of an L-shaped bracket. The output end of motor A is connected to a threaded rod for driving a moving block, and one end of the threaded rod extends to one side of the L-shaped bracket. The moving block is screwed onto the surface of the threaded rod. The heating rod limit switch is connected to the side of the moving block. Motor A, as the power source of the driving mechanism, converts electrical energy into mechanical energy to provide power for the rotation of the threaded rod. Motor A and the side of the L-shaped bracket are securely connected by connecting parts such as a fixed seat to ensure that motor A will not shake or shift during operation. The threaded rod and the output end of motor A are connected by components such as a coupling to accurately transmit the rotational motion of motor A to the threaded rod. Since the moving block is screwed onto the surface of the threaded rod, when the threaded rod rotates under the drive of motor A, according to the principle of screw transmission, the moving block will move linearly along the axial direction of the threaded rod. The heating rod limit switch is fixed to the side of the moving block and moves with the moving block, thereby achieving precise control of the heating timing of the heating rod and ensuring that the cigarette lighting operation can be accurately executed according to the predetermined procedure.

[0012] Preferably, the movable block is connected to a limiting block on its side, and the limiting block slides inside the guide rail block. The limiting block and the movable block are fixedly connected by welding, screws, or other means to ensure that they will not separate during movement. The limiting block and the track inside the guide rail block are fitted with a clearance, which ensures that the limiting block slides smoothly within the track and also provides a good limiting function. This structural design effectively restricts the degree of freedom of movement of the movable block, allowing it to move only in the straight line direction defined by the guide rail block. This prevents the movable block from shifting or rotating due to external interference or its own inertia during movement, ensuring that the heating rod limit switch can move accurately to the position corresponding to the heating rod body. This ensures that the heating rod body heats up at the correct time, improving the accuracy and reliability of the cigarette lighting operation.

[0013] Preferably, a positioning frame is provided inside the housing on one side of the L-shaped bracket, and a motor B is provided on one side of the positioning frame. The output end of the motor B is connected to a drive rod, which passes through the positioning frame. The positioning frame is installed inside the housing to support and fix the motor B and the drive rod, ensuring their stability during operation. The positioning frame is fixed to the inside of the housing by screws, nuts, and other connecting parts to ensure that the motor B and the drive rod will not loosen or shift when they are running. The motor B serves as the power source for the smoke replacement operation, driving its output shaft to rotate via electrical energy, which in turn drives the drive rod to rotate. The drive rod passes through the positioning frame, and the positioning frame is equipped with bearings or bushings that match the drive rod, which can reduce the frictional resistance when the drive rod rotates, ensuring that the drive rod can rotate smoothly and stably, providing stable power transmission for subsequent smoke replacement operations.

[0014] Preferably, one end of the drive rod is connected to a cigarette tray, and one side of the cigarette tray is connected with positioning cylinders for installing cigarette sticks at equal intervals. The drive rod and the cigarette tray are fixedly connected by key connections, pin connections, or other means to ensure that the drive rod can reliably drive the cigarette tray to rotate synchronously when rotating. The cigarette tray is the component that carries the cigarette sticks, and the positioning cylinders set at equal intervals on its surface are used to fix the cigarette sticks. The number and spacing of the positioning cylinders can be designed and adjusted according to actual needs. The inner diameter of the positioning cylinder is slightly smaller than the outer diameter of the cigarette stick. The cigarette sticks are securely installed between the positioning cylinders and the cigarette tray by interference fit or other means, ensuring that the cigarette sticks will not loosen or fall off during the rotation of the cigarette tray, ensuring the smooth operation of cigarette changing, and also ensuring that the cigarette sticks are in the accurate position every time a cigarette is lit.

[0015] Preferably, the cigarette stick is positioned between the positioning cylinder and the cigarette tray. When the cigarette tray rotates under the drive of the drive rod, the cigarette stick can rotate with the cigarette tray and sequentially reach the ignition position corresponding to the heating rod. This installation method not only facilitates the installation and replacement of the cigarette stick, but also ensures that the cigarette stick maintains a suitable distance and angle from the heating rod when igniting, ensuring that the cigarette stick can be reliably ignited and improving the success rate and stability of ignition.

[0016] Preferably, a baffle is connected to one side of the L-shaped bracket, which is located on the side of the motor A. The baffle is fixed to the L-shaped bracket by means of screws or welding, and its position is exactly on the side of the motor A. The main function of the baffle is to protect the motor A, preventing external dust, debris, etc. from entering the motor A and avoiding malfunctions caused by dust accumulation or debris entering the motor A, which would affect the normal operation of the drive mechanism. At the same time, the baffle can also prevent operators from accidentally touching the motor A to a certain extent, ensuring the safety of operators and improving the safety and reliability of equipment operation.

[0017] Preferably, the bolt extends through the housing to the surface of the L-shaped heating rod support. The surface of the housing has threaded holes for bolting the bolts. The bolts and threaded holes are fitted with standard threads. By tightening the bolts, the L-shaped heating rod support can be firmly fixed to the housing, ensuring that the L-shaped heating rod support will not loosen or shift during operation. This ensures the stability of the heating rod and allows for accurate ignition of the cigarette. This connection method is simple in structure and easy to install. Furthermore, when it is necessary to disassemble or maintain the L-shaped heating rod support or the heating rod, only the appropriate tools need to be used to unscrew the bolts, reducing the difficulty and cost of equipment maintenance and improving the maintainability of the equipment.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) The automatic cigarette lighting mechanism realizes the automated operation of the cigarette lighting and cigarette replacement process through the drive components such as motor A and motor B. It eliminates the need for manual operation of cigarette lighting and cigarette replacement, reduces manpower input, and improves work efficiency. At the same time, the heating rod is used to ignite the cigarette stick, avoiding manual operation, reducing manpower input, and avoiding fatigue and errors caused by manual operation.

[0020] (2) Through the cooperation of the moving block with the threaded rod, the guide block and the limit block, and the precise control of the heating rod body by the heating rod limit switch, the cigarette lighting process can be executed precisely, the heating timing and position of the heating rod body can be accurately controlled, and the cigarette can be accurately lit every time, thus improving the success rate and consistency of cigarette lighting.

[0021] (3) By controlling the rotation of the cigarette tray by motor B, the accuracy of the cigarette changing process is ensured, and the next cigarette stick can be accurately moved to the designated position, meeting the strict requirements of different test scenarios on the amount of smoke and the order of lighting cigarettes.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] Please see Figure 1-2 This utility model provides a technical solution: an automatic cigarette lighting mechanism for simulating human smoking, including: a housing 17, an L-shaped bracket 1 provided on the inner side of the housing 17, and a guide rail block 4 for limiting the position provided on the inner side of the L-shaped bracket 1;

[0028] L-shaped heating rod support 9 is located on the side of the housing 17. Bolts 18 are connected to the side of the L-shaped heating rod support 9. The L-shaped heating rod support 9 is mainly used to install and fix the heating rod 10. Its L-shaped structure design can make reasonable use of the space on the side of the housing 17 to fix the heating rod 10 in a suitable position, which facilitates the ignition of the cigarette stick 11.

[0029] Heating rod 10 is disposed on the surface of L-shaped heating rod support 9 and is used to ignite cigarette stick 11. Heating rod 10 is the core component for realizing the cigarette lighting function. It generates high temperature by converting electrical energy into heat energy. When the appropriate temperature is reached, it can quickly ignite cigarette stick 11. Heating rod 10 is installed on the surface of L-shaped heating rod support 9 and is connected to the control system through a specific electrical connection method. The control system can accurately control the heating time and temperature of heating rod 10 according to the set program or instructions to ensure that the ideal effect is achieved every time cigarette is lit.

[0030] The L-shaped bracket 1 is equipped with a driving mechanism. The moving block 5 of the driving mechanism works in conjunction with the heating rod limit switch 6 to control the heating rod body 10 to heat up. The moving block 5 and the heating rod limit switch 6 work closely together. When the moving block 5 moves under the action of the driving mechanism, the heating rod limit switch 6 moves accordingly. When the heating rod limit switch 6 moves to a specific position corresponding to the heating rod body 10, it will trigger a switch action and send a signal to the control system. After receiving the signal, the control system will control the heating rod body 10 to start heating up, realizing the function of automatic cigarette lighting. The whole process does not require manual intervention, which improves the efficiency and accuracy of cigarette lighting.

[0031] The driving mechanism includes a motor A2 connected to the side of an L-shaped bracket 1. The output end of motor A2 is connected to a threaded rod 7 for driving a movable block 5, with one end of the threaded rod 7 extending to one side of the L-shaped bracket 1. The movable block 5 is screwed onto the surface of the threaded rod 7. A heating rod limit switch 6 is connected to the side of the movable block 5. Motor A2 serves as the power source for the driving mechanism, converting electrical energy into mechanical energy to provide power for the rotation of the threaded rod 7. Motor A2 is securely connected to the side of the L-shaped bracket 1 via a fixing seat or other connecting components to ensure that motor A2 does not overheat during operation. If there is any shaking or displacement, the threaded rod 7 is connected to the output end of the motor A2 through a coupling and other components, which can accurately transmit the rotational motion of the motor A2 to the threaded rod 7. Since the moving block 5 is screwed onto the surface of the threaded rod 7, when the threaded rod 7 rotates under the drive of the motor A2, according to the principle of screw transmission, the moving block 5 will move linearly along the axial direction of the threaded rod 7. The heating rod limit switch 6 is fixed on the side of the moving block 5 and moves with the moving block 5, thereby realizing precise control of the heating timing of the heating rod body 10 and ensuring that the cigarette lighting operation can be accurately executed according to the predetermined program.

[0032] The movable block 5 is connected to a limiting block 8 on its side, and the limiting block 8 is slidably mounted inside the guide rail block 4. The limiting block 8 and the movable block 5 are fixedly connected by welding, screws, or other means to ensure that they will not separate during movement. The limiting block 8 and the track inside the guide rail block 4 are fitted with a clearance, which ensures that the limiting block 8 slides smoothly within the track and also provides a good limiting function. This structural design effectively restricts the degree of freedom of movement of the movable block 5, allowing it to move only in the straight line direction defined by the guide rail block 4. This prevents the movable block 5 from shifting or rotating due to external interference or its own inertia during movement, ensuring that the heating rod limit switch 6 can move accurately to the position corresponding to the heating rod body 10, thereby ensuring that the heating rod body 10 heats up at the correct time and improving the accuracy and reliability of the cigarette lighting operation.

[0033] Inside the housing 17, a positioning frame 14 is located on one side of the L-shaped bracket 1. A motor B15 is located on one side of the positioning frame 14. The output end of the motor B15 is connected to a drive rod 16, which passes through the positioning frame 14. The positioning frame 14 is installed inside the housing 17 to support and fix the motor B15 and the drive rod 16, ensuring their stability during operation. The positioning frame 14 is fixed to the inside of the housing 17 by screws, nuts, and other connecting parts, ensuring that the motor B15 and the drive rod 16 will not loosen or shift during operation. The motor B15 serves as the power source for the smoke replacement operation, driving its output shaft to rotate via electrical energy, which in turn drives the drive rod 16 to rotate. The drive rod 16 passes through the positioning frame 14, and the positioning frame 14 is equipped with bearings or bushings that match the drive rod 16, reducing frictional resistance during the rotation of the drive rod 16 and ensuring that the drive rod 16 can rotate smoothly and stably, providing stable power transmission for subsequent smoke replacement operations.

[0034] One end of the drive rod 16 is connected to a cigarette tray 13. Positioning cylinders 12 for mounting cigarette sticks 11 are evenly spaced on one side of the surface of the cigarette tray 13. The drive rod 16 and the cigarette tray 13 are fixedly connected by key connections, pin connections, or other means to ensure that the drive rod 16 can reliably drive the cigarette tray 13 to rotate synchronously when rotating. The cigarette tray 13 is the component that carries the cigarette sticks 11. The positioning cylinders 12 evenly spaced on its surface are used to fix the cigarette sticks 11. The number and spacing of the positioning cylinders 12 can be designed and adjusted according to actual needs. The inner diameter of the positioning cylinders 12 is slightly smaller than the outer diameter of the cigarette sticks 11. The cigarette sticks 11 are securely installed between the positioning cylinders 12 and the cigarette tray 13 by interference fit or other means, ensuring that the cigarette sticks 11 will not loosen or fall off during the rotation of the cigarette tray 13, ensuring the smooth operation of cigarette changing, and also ensuring that the cigarette sticks 11 are in the accurate position every time a cigarette is lit.

[0035] The cigarette stick 11 is positioned between the positioning cylinder 12 and the cigarette tray 13. When the cigarette tray 13 rotates under the drive of the drive rod 16, the cigarette stick 11 can rotate together with the cigarette tray 13 and sequentially reach the lighting position corresponding to the heating rod 10. This installation method not only facilitates the installation and replacement of the cigarette stick 11, but also ensures that the cigarette stick 11 maintains a suitable distance and angle from the heating rod 10 when lighting cigarettes, ensuring that the cigarette stick 11 can be reliably lit and improving the success rate and stability of lighting cigarettes.

[0036] A baffle 3 is connected to one side of the L-shaped bracket 1, located next to the motor A2. The baffle 3 is fixed to the L-shaped bracket 1 by screws or welding, and its position is exactly on the side of the motor A2. The main function of the baffle 3 is to protect the motor A2, preventing external dust and debris from entering the motor A2 and avoiding malfunctions caused by dust accumulation or debris, which would affect the normal operation of the drive mechanism. At the same time, the baffle 3 can also prevent operators from accidentally touching the motor A2, ensuring the safety of operators and improving the safety and reliability of equipment operation.

[0037] The bolt 18 passes through the housing 17 and extends to the surface of the L-shaped heating rod support 9. The surface of the housing 17 has a screw hole 19 for screwing the bolt 18. The bolt 18 and the screw hole 19 are fitted with a standard thread. By tightening the bolt 18, the L-shaped heating rod support 9 can be tightly fixed to the housing 17, ensuring that the L-shaped heating rod support 9 will not loosen or shift during operation, thereby ensuring the stable position of the heating rod 10 and accurately igniting the cigarette stick 11. This connection method is simple in structure and easy to install. When it is necessary to disassemble and maintain the L-shaped heating rod support 9 or the heating rod 10, only the appropriate tool needs to be used to unscrew the bolt 18, which reduces the difficulty and cost of equipment maintenance and improves the maintainability of the equipment.

[0038] Specifically, during use, before the automatic cigarette lighting mechanism for simulating human smoking starts working, the cigarette stick 11 is placed between the positioning cylinder 12 on the surface of the cigarette tray 13 and the cigarette tray 13 to complete the installation preparation work of the cigarette stick 11.

[0039] When the system issues a cigarette-lighting command, motor A2 starts. The threaded rod 7 connected to the output end of motor A2 begins to rotate under the drive of motor A2. Since the moving block 5 is screwed onto the surface of the threaded rod 7, according to the principle of screw transmission, the rotating threaded rod 7 will drive the moving block 5 to move along the axial direction of the threaded rod 7. The limiting block 8 connected to the side of the moving block 5 slides inside the guide rail block 4. The limiting structure composed of the guide rail block 4 and the limiting block 8 can ensure that the moving block 5 moves along the predetermined straight line direction during the movement, avoids deviation, and ensures the stability and accuracy of the movement.

[0040] As the moving block 5 moves, when the heating rod limit switch 6 connected to the side of the moving block 5 moves to a specific position corresponding to the heating rod body 10, the heating rod limit switch 6 is triggered. At this time, the heating rod limit switch 6 sends a signal to the heating rod body 10 to control the heating rod body 10 to start heating. The heating rod body 10 is installed on the surface of the L-shaped heating rod bracket 9. The L-shaped heating rod bracket 9 is connected and fixed to the housing 17 by bolts 18 to ensure that the heating rod body 10 maintains a stable position during the heating process. The heat generated by the heating rod body 10 ignites the cigarette stick 11, completing the cigarette lighting operation.

[0041] After the cigarette is lit, when the predetermined conditions are met (such as the number of cigarettes reaching a set value), the motor B15 starts. The drive rod 16 connected to the output end of the motor B15 passes through the positioning frame 14. Driven by the motor B15, the drive rod 16 starts to rotate. The cigarette tray 13 connected to one end of the drive rod 16 rotates with the rotation of the drive rod 16. The positioning cylinders 12 connected at equal intervals on the surface of the cigarette tray 13 also rotate. During the rotation, the lit cigarette stick 11 is removed, and the next positioning cylinder 12 containing the cigarette stick 11 rotates to the position corresponding to the heating rod body 10, preparing for the next cigarette lighting, thus realizing the function of automatic cigarette replacement.

[0042] Throughout the entire operation, the baffle 3 connected to the side of motor A2 on one side of the L-shaped bracket 1 serves a protective function, preventing the motor A2 and other components from being accidentally bumped or interfered with by other external factors during operation, thus ensuring the normal operation of the mechanism. At the same time, the L-shaped heating rod bracket 9 is installed by bolts 18 and screw holes 19 on the housing 17. This installation method facilitates the disassembly and maintenance of the L-shaped heating rod bracket 9 and the heating rod body 10, improving the maintainability of the equipment.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
