[0036] In related technologies, hookahs generally heat tobacco paste with a lighter to produce smoke. The lighter includes a housing assembly, a heating unit, and a heat-conducting component. The heating unit and the heat-conducting component are respectively located inside the housing assembly, and the heat-conducting component is in contact with the heating unit. When the lighter is working, the heat generated by the heating unit is transferred to the tobacco paste through the heat-conducting component. The heat generated by the heating unit is radiated to the housing assembly, resulting in a high temperature of the housing assembly and affecting its service life.

[0037] Reference Figures 1 to 5 According to an embodiment of the present invention, a cigarette lighter includes a housing assembly 100, a heat insulation assembly 200, a heat-conducting element 300, and a heating unit 400. The heat insulation assembly 200 has a heat insulation cavity 201 and a notch 202 communicating with the heat insulation cavity 201. The heat insulation assembly 200 is disposed inside the housing assembly 100. The heat-conducting element 300 includes a connecting part 310 and a heat-conducting part 320 connected to the connecting part 310. The connecting part 310 is disposed inside the heat insulation cavity 201, and the heat-conducting part 320 extends out of the notch 202. The heating unit 400 is disposed inside the heat insulation cavity 201, and the heating unit 400 contacts the heat-conducting part 320. In this way, the heat generated by the heating unit 400 during operation is effectively blocked from directly radiating and conducting to the housing assembly 100. The heat is confined inside the heat insulation cavity 201 and is mainly directionally transferred to the external tobacco paste through the heat-conducting part 320, thereby significantly reducing the operating temperature of the housing assembly 100 and improving the service life and safety of the cigarette lighter.

[0038] For example, when the cigarette lighter is working, the heating unit 400 is activated, and the heat generated by the heating unit 400 is directionally transferred to the external cigarette paste through the heat conduction part 320. By setting the heat insulation component 200, the heat generated by the heating unit 400 is confined inside the heat insulation cavity 201, thereby significantly reducing the working temperature of the housing assembly 100 and improving the service life and safety of the cigarette lighter.

[0039] It should be noted that the heating unit 400 can be an infrared heater, an electromagnetic heater, or a resistive heater, etc., and there are no restrictions here.

[0040] Reference Figure 5 In some embodiments of this utility model, the heat insulation component 200 includes a heat insulation seat 210 and a heat insulation cover 220 covering the heat insulation seat 210. The heat insulation seat 210 and the heat insulation cover 220 enclose to form a heat insulation cavity 201. A notch 202 is provided in the heat insulation seat 210. The heat insulation seat 210 is provided with an annular protrusion 211, which abuts against the inner peripheral wall of the heat insulation cover 220. On the one hand, the separate structure of the heat insulation seat 210 and the heat insulation cover 220 facilitates production and assembly. On the other hand, the design of the annular protrusion 211 abutting against the inner peripheral wall of the heat insulation cover 220 enhances the sealing of the heat insulation cavity 201, further preventing heat leakage from the joint between the heat insulation seat 210 and the heat insulation cover 220, improving the heat insulation effect, and thus improving the heat insulation performance of the heat insulation component 200.

[0041] It should be noted that the heat insulation base 210 and the heat insulation cover 220 can be made of materials with low thermal conductivity, such as ceramic or polyester plastic, and there are no restrictions on this.

[0042] Reference Figure 5 In some embodiments of this utility model, the housing assembly 100 includes a bottom shell 110 and a cover 120 covering the bottom shell 110. The cover 120 is provided with a first through hole 121, the heat insulation cover 220 is provided with a second through hole 221, and the heat-conducting component 300 is provided with a third through hole 321. The first through hole 121, the second through hole 221, and the third through hole 321 are sequentially connected to form a connecting channel, so that air can enter the connection between the tobacco paste and the heat-conducting component 320 through the connecting channel, which helps to accelerate the combustion speed of the tobacco paste and thus improve the user experience.

[0043] In some embodiments of this utility model, the bottom shell 110 and the cover 120 are detachably connected, which makes it convenient for users or maintenance personnel to open the shell for maintenance, cleaning or replacement of internal components (such as the heating unit 400), greatly improving the maintainability of the cigarette lighter and the user experience.

[0044] It should be noted that the bottom shell 110 can be detachably connected to the cover 120 by bolts or clips, which will not be elaborated here.

[0045] Reference Figure 5 In some embodiments of this utility model, the housing assembly 100 further includes a connector 130. The two ends of the connector 130 are respectively connected to the cover 120 and the heat insulation cover 220. The connector 130 is provided with a fourth through hole 131, which connects to the first through hole 121 and the second through hole 221. The connector 130 not only serves to connect and fix the heat insulation cover 220, but its fourth through hole 131 design ensures smooth and aligned communication between the first through hole 121 and the second through hole 221, avoiding blockage due to assembly errors. Simultaneously, this structure makes the positioning of the heat insulation assembly 200 more accurate and assembly simpler.

[0046] In some embodiments of this utility model, the connecting part 310 and the heat-conducting part 320 are an integral structure, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the cigarette lighter.

[0047] For example, the connecting part 310 and the heat-conducting part 320 can be integrally formed by die casting, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the cigarette lighter.

[0048] In another embodiment, the connecting part 310 and the heat-conducting part 320 can also be connected and fixed by welding, wherein the welding method includes, but is not limited to, resistance welding, laser welding or ultrasonic welding.

[0049] Reference Figure 5 , Figure 6 In some embodiments of this utility model, the heat-conducting part 320 is provided with a plurality of arrayed protrusions 322 on the side away from the heat insulation component 200, and gaps are formed between adjacent protrusions 322. Air can enter the connection between the heat-conducting part 320 and the tobacco paste through the gaps, which is beneficial to the combustion of the tobacco paste and thus improves the user experience.

[0050] In some embodiments of this utility model, a controller and a power module 500 are also included. The controller is located inside the housing assembly 100 and electrically connected to the heating unit 400. The controller is used to control the start or stop of the heating unit 400. The power module 500 is located in the housing assembly 100 and electrically connected to the controller to supply power to the controller. This realizes precise start and stop control of the heating unit 400. Users can heat as needed, avoiding energy waste and the risk of overheating that may be caused by continuous heating, making the product smarter, more energy-efficient, and safer.

[0051] Reference Figure 7In some embodiments of this utility model, the power module 500 includes a battery compartment 510 and a battery 520. The battery compartment 510 is provided with a receiving cavity 511, and the battery 520 is disposed in the receiving cavity 511. The battery 520 is electrically connected to the controller. A limiting structure is provided between the battery compartment 510 and the housing assembly 100, which realizes convenient installation and fixation of the power module 500 and the housing assembly 100, ensuring the reliability of the connection and facilitating the replacement of the battery 520.

[0052] It should be noted that the battery 520 can be a lithium battery 520 or a dry cell battery 520, and there is no restriction here.

[0053] Reference Figure 7 , Figure 8 In some embodiments of this utility model, the limiting structure includes a limiting member 600, a limiting groove 512, a guide strip 513, and a guide groove 101. The guide strip 513 and the limiting groove 512 are respectively disposed on the top of the battery compartment 510, and the guide groove 101 is disposed on the housing assembly 100. The limiting member 101 is movably disposed on the housing assembly 100 to enter or exit the limiting groove 512. The guide strip 513 is movably inserted through the guide groove 101, and the guide strip 513 abuts against the side wall of the guide groove 101. The length direction of the guide strip 513 is staggered with the moving direction of the limiting member 600, which realizes the quick assembly and disassembly between the battery compartment 510 and the housing assembly 100, while ensuring the connection strength and preventing loosening during use.

[0054] For example, when installing the power module 500, the limiting member 600 can move vertically, and the guide strip 513 extends horizontally. When the limiting member 600 moves downward into the limiting groove 512, it abuts against the side wall of the limiting groove 512 to restrict the battery compartment 510 from moving along the length of the guide strip 513. The guide strip 513 passes through the guide groove 101 and abuts against the side wall of the guide groove 101, thus restricting the battery compartment 510 from moving vertically and horizontally. When disassembling the power module 500, the limiting member 600 is moved upward to exit the limiting groove 512, and the battery compartment 510 can be pulled out along the length of the guide strip 513. The operation is simple, convenient, and quick, realizing the rapid assembly and disassembly between the battery compartment 510 and the housing assembly 100, while ensuring the connection strength and preventing loosening during use.

[0055] It should be noted that the positions of the guide bar 513 and the guide groove 101 can be interchanged, that is, the guide bar 513 is located in the housing assembly 100 and the guide groove 101 is located in the battery compartment 510, without any restrictions.

[0056] As another implementation, the limiting structure can also be a bolt or screw. For example, the bolt passes through the battery compartment and is threaded to the housing assembly, which can also connect and fix the battery compartment and the housing assembly 100, which will not be described in detail here.

[0057] It should be noted that an elastic element 610 is provided between the limiting member 600 and the housing assembly 100. The elastic element 610 is a component that can undergo axial elastic deformation, such as a compression spring or a rubber component. The elastic element 610 is used to move the limiting member 600 in the direction of entering the limiting groove 512, so as to simplify the user operation and improve the user experience.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
