Description

Technical Field

[0001] The utility model relates to the technical field of cigarette lighters, and more specifically, to a push-type automobile cigarette lighter. Background Art

[0002] In the existing technology, the unstable connection between the cigarette lighter and the bottom heater in the push-type automobile cigarette lighter is a common problem. Especially during the operation of the vehicle, when the vehicle body vibrates or shakes, the cigarette lighter is easy to detach or loosen, causing the cigarette lighter to jump out of the fixed position and unable to work stably. This problem not only affects the normal use of the cigarette lighter, but also may bring safety hazards. Therefore, the design needs to optimize and improve the connection structure to improve the stability between the cigarette lighter and the heater.

[0003] In the traditional push-type car cigarette lighter design, the cigarette lighter is usually connected to the bottom heater through some mechanical connection method. The function of the cigarette lighter is to generate high temperature through electrical contact with the heater to light cigarettes or other objects, while the bottom heater is responsible for heating the cigarette lighter. However, due to the vibration of the in-car environment and frequent operations, the connection between the cigarette lighter and the heater is often affected by external forces, resulting in poor contact or looseness. When the connection is loose, the cigarette lighter may be separated from the original installation position, resulting in its inability to heat or light cigarettes normally. Utility Model Content

[0029] Please refer to Figures 1 - 5, A push-type car cigarette lighter, comprising a bottom sleeve 1, a push-type cigarette lighter mechanism, a stable connection mechanism and an auxiliary disassembly mechanism. The push-type cigarette lighter mechanism includes a handle sleeve 2, a push block 3, a push-back spring 4 and a cigarette lighter wire 5. The push block 3 is slidably installed in the handle sleeve 2. The push-back spring 4 is installed between the outer wall of the push block 3 and the inner wall of the handle sleeve 2. The cigarette lighter wire 5 is installed at the bottom end of the push block 3. The stable connection mechanism includes a clamping pipe 6, a clamping rod 7, a rotating sleeve 8, a pushing frame 9, a limiting tooth 10, a rotating sleeve 11, a spring-winding rod 12, a connecting block 13 and a toothed plate 14. The clamping pipe 6 can be sleeved with the clamping rod 7. The rotating sleeve 8 is installed on the side wall of the clamping pipe 6 in a limited rotation manner. The pushing frame 9 is threadedly connected to the inner wall of the rotating sleeve 8. The limiting tooth 10 is installed at one end of the rotating sleeve 8. The spring-winding rod 12 is installed on the outer wall of the clamping pipe 6. The connecting block 13 is rotatably and slidably installed on the spring-winding rod 12. The toothed plate 14 is installed at the top end of the connecting block 13. The toothed plate 14 is meshed and connected with the limiting tooth 10. The rotating sleeve 8 is installed on the outer wall of the clamping pipe 6 in a limited rotation manner. The inner wall of the rotating sleeve 8 is connected to the outer wall of the connecting block 13.

[0030] In this embodiment, during use, when the push block 3 is pressed downward, the push-back spring 4 is compressed, so that the cigarette lighter wire 5 at the bottom contacts the heating component 20. The buckle component locks the push block 3. The cigarette lighter wire 5 is heated by the heating component 20 to reach the cigarette lighting temperature. After the buckle component releases the push block 3, the elastic force of the push-back spring 4 causes the push block 3 to rebound and reset. During the whole process, the first power supply piece 22 provides power for the heating component 20 to ensure the heating effect. The top plate 23 on the side of the handle sleeve 2 is connected to the bottom plate 24 of the bottom sleeve 1 through the stable connection mechanism to ensure the stability of the overall structure. The stable connection mechanism realizes the reliable connection between the handle sleeve 2 and the bottom sleeve 1. The clamping pipe 6 is fixed on the top plate 23 through the connecting plate 25 and can be sleeved with the clamping rod 7 fixed on the bottom plate 24. The rotating sleeve 8 is rotatably limited on the side wall of the clamping pipe 6 and forms a screw drive with the pushing frame 9. The meshing of the limiting tooth 10 and the toothed plate 14 controls the rotation of the rotating sleeve 8. The connecting block 13 on the spring-winding rod 12 can rotate and slide. The toothed plate 14 on its top cooperates with the limiting tooth 10 to form an accurate rotation control system. The pushing frame 9 slides in the guiding groove 26 to ensure the accuracy of the movement. This design not only ensures the reliability of the connection but also facilitates disassembly and separation.

[0031] The auxiliary disassembly mechanism includes a bottom fixing plate 15, a tightening spring 16, tightening blocks 17 and a rotating block 18. The bottom fixing plate 15 is fixedly installed at the bottom end of the clamping pipe 6. The rotating block 18 is installed at the bottom end of the rotating sleeve 11. Multiple groups of tightening blocks 17 are slidably installed toward the center at the top end of the bottom fixing plate 15. The tightening spring 16 is installed between adjacent tightening blocks 17. The tightening blocks 17 can be pressed against the outer end of the rotating block 18 to stably rotate the rotating sleeve 11, drive the toothed plate 14 to rotate, make the limiting tooth 10 rotate, and the pushing frame 9 extends into or away from the clamping groove 201.

[0032] In this embodiment, the bottom fixing plate 15 is fixed to the bottom of the clamping pipe 6. A plurality of tightening blocks 17 slide centripetally on its top. The tightening spring 16 provides continuous pressure between adjacent tightening blocks 17, so that the tightening blocks 17 always press against the rotating block 18 at the bottom of the rotating sleeve 11, ensuring that the rotation of the rotating sleeve 11 is stable and controllable. Furthermore, the toothed plate 14 is driven to rotate, enabling the limiting teeth 10 and the propulsion frame 9 to work together to achieve precise control of the clamping structure.

[0033] Please refer to Figures 1 - 5 , as a supplementary implementation manner of a push-type vehicle cigarette lighter for the push point cigarette mechanism, the stable connection mechanism, and the auxiliary disassembly mechanism: A snap component 19 and a heating component 20 are installed inside the bottom sleeve 1, and a guiding connection frame 21 is installed on the side of the bottom sleeve 1. The bottom sleeve 1 is connected in cooperation with the installation position through the guiding connection frame 21. A first power supply sheet 22 penetrates through the bottom end of the bottom sleeve 1, and the first power supply sheet 22 is electrically connected to the heating component 20 in cooperation. A top plate 23 is installed on the side of the handle sleeve 2, and a bottom plate 24 is installed on the side of the bottom sleeve 1. The top plate 23 and the bottom plate 24 are connected through the stable connection mechanism. A connecting plate 25 is installed at the bottom end of the side wall of the clamping pipe 6, and the connecting plate 25 is fixedly installed on the top end surface of the top plate 23. One end of the clamping rod 7 is fixedly installed on the bottom plate 24. The clamping pipe 6 on the top plate 23 can sleeved the clamping rod 7 into the clamping pipe 6 to achieve the clamping of the clamping rod 7 and the clamping pipe 6. A guiding groove 26 is horizontally opened on the side wall of the clamping pipe 6, and the top end and the bottom end of the propulsion frame 9 are slidably guided in cooperation.

[0034] More specifically, when the user uses the cigarette lighter, first press the pressing block 3. The pressing block 3 moves downward as it is pressed. At the same time, the cigarette lighter wire 5 also starts to heat up, forming a high-temperature area to light the cigarette. This process is mainly completed by the push point cigarette mechanism. At the same time, the stable connection mechanism ensures that the push point cigarette mechanism can operate stably, avoiding functional failures caused by vibration or external interference. The precise design of the clamping rod 7 and the clamping pipe 6 ensures that the pressing block 3 is always in the correct position during use. The cooperation between the rotating sleeve 8 and the propulsion frame 9 also ensures the stability of the cigarette lighter. If the user needs to disassemble and use the cigarette lighter, through the mutual cooperation of the rotating block 18 and the tightening block 17, the rotating sleeve 11 drives the toothed plate 14 to rotate, so that the propulsion frame 9 can easily extend into or away from the card slot 201 to complete the disassembly process.

[0035] In summary, when the overall device is in use or operation: when it is necessary to press the cigarette lighter mechanism to operate, during use, press the pressing block 3 downward to compress the reverse push spring 4, so that the cigarette lighter wire 5 at the bottom contacts the heating component 20. The buckle component locks the pressing block 3. The cigarette lighter wire 5 is heated by the heating component 20 to reach the cigarette lighting temperature. After the buckle component releases the pressing block 3, the elastic force of the reverse push spring 4 causes the pressing block 3 to rebound and reset. During the whole process, the first power supply piece 22 provides power for the heating component 20 to ensure the heating effect. The top plate 23 on the side of the handle sleeve 2 is connected to the bottom plate 24 of the bottom sleeve 1 through a stable connection mechanism to ensure the stability of the overall structure.

[0036] When it is necessary to operate the stable connection mechanism, the stable connection mechanism realizes the reliable connection between the handle sleeve 2 and the bottom sleeve 1. The clamping pipe 6 is fixed on the top plate 23 through the connecting plate 25 and can be sleeved on the clamping rod 7 fixed on the bottom plate 24. The rotating sleeve 8 rotates in a limited way on the side wall of the clamping pipe 6 and forms a threaded drive with the pushing frame 9. The engagement of the limiting tooth 10 and the tooth plate 14 controls the rotation of the rotating sleeve 8. The connecting block 13 on the spring winding rod 12 can rotate and slide. The tooth plate 14 at its top cooperates with the limiting tooth 10 to form an accurate rotation control system. The pushing frame 9 slides in the guiding groove 26 to ensure the accuracy of the movement, which not only ensures the reliability of the connection but also facilitates disassembly and separation.

[0037] When it is necessary to operate the auxiliary disassembly mechanism, the bottom fixing plate 15 is fixed at the bottom of the clamping pipe 6. Multiple groups of tightening blocks 17 slide centripetally on its top. The tightening spring 16 provides continuous pressure between adjacent tightening blocks 17, so that the tightening blocks 17 always press against the rotating block 18 at the bottom of the rotating sleeve 11 to ensure the smooth and controllable rotation of the rotating sleeve 11, and then drives the tooth plate 14 to rotate, so that the limiting tooth 10 and the pushing frame 9 work together to realize the precise control of the clamping structure.

[0038] When the user uses the cigarette lighter, first press the pressing block 3. The pressing block 3 moves downward as it is pressed. At the same time, the cigarette lighter wire 5 will also start to be heated to form a high-temperature area to light the cigarette. This process is mainly completed by the pressing cigarette lighter mechanism. At the same time, the stable connection mechanism ensures that the pressing cigarette lighter mechanism can operate stably, avoiding functional failure caused by vibration or external interference. The precise design of the clamping rod 7 and the clamping pipe 6 ensures that the pressing block 3 is always in the correct position during use, and the cooperation between the rotating sleeve 8 and the pushing frame 9 also ensures the stability of the cigarette lighter. If the user needs to disassemble and use the cigarette lighter, through the mutual cooperation of the rotating block 18 and the tightening blocks 17, the rotating sleeve 11 drives the tooth plate 14 to rotate, so that the pushing frame 9 can easily extend into or away from the card slot 201 to complete the disassembly process.

[0039] Among all the solutions mentioned above, for those involving the connection between two components, welding, the cooperation connection of bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those involving fixed connection mentioned above, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
