Description

Technical Field

[0001] This invention relates to the field of cigarette lighter technology, and more specifically, to a cigarette lighter with lighting function and its control method. Background Technology

[0002] A lighter is a small fire-starting device. It is mainly used for starting a fire, smoking, and also for cooking and other purposes. The main components of a lighter are the ignition mechanism and the gas tank. When the ignition mechanism activates, it emits a spark that ignites the gas. The ignition mechanism is the most dynamic part of the lighter's evolution and also its most complex structure. Based on the characteristics of the ignition mechanism, lighters can be divided into six types: flint and steel wheel lighters, piezoelectric ceramic lighters, magnetic induction lighters, battery-powered lighters, solar-powered lighters, and microcomputer-controlled lighters. The gas used in lighters is primarily a flammable gas.

[0003] Currently, portable lighters on the market consist of the lighter body. These lighters have relatively limited functions, rarely including lighting. Furthermore, the traditional lighting structure is not simple enough, resulting in relatively poor practicality. Moreover, traditional lighters with lighting functions have inconvenient structural designs, especially since the lighting angle cannot be adjusted, leading to limited use. They also lack the functionality of multiple adjustable flashlight modules. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a cigarette lighter with lighting function that features multiple flashlight modules, is highly practical, has a simple structure, and has lighting capabilities, as well as its control method.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cigarette lighter with lighting function, comprising a housing and a cigarette lighter assembly disposed within the housing. The cigarette lighter assembly includes a rotating housing disposed on and rotatably connected to the housing, a cigarette lighter module disposed on surface A of the rotating housing, a flashlight module disposed on surface B of the rotating housing, a reading module disposed on surface C of the rotating housing, a power storage device disposed within the housing and electrically connected to each module, and a control module disposed within the housing. The rotating housing is configured to maintain a continuous path to the power storage device by forming a rotatable connection with the housing. Through the control module disposed within the housing, the simultaneous use of the practical functions of different modules can be achieved. A damped rotation positioning structure is also provided between the housing and the rotating housing. The damped rotation positioning structure includes an elastic positioning component disposed between the housing and the rotating housing and a plurality of positioning grooves disposed on the rotating housing. The elastic positioning component includes a positioning bead and an elastic element abutting against the positioning bead. The positioning bead is configured to sequentially engage with each positioning groove when the rotating housing rotates to form a multi-position positioning.

[0006] The present invention is further configured such that: the rotating housing is provided with an elastic sealing structure, which is located at the junction of the rotating housing and the housing, including an annular sealing groove embedded in the end face of the rotating housing and an elastic sealing ring disposed in the annular sealing groove, wherein the elastic sealing ring is configured to form a sealing contact when the rotating housing and the housing are joined.

[0007] The invention is further configured such that: the bottom of the annular sealing groove is provided with a guide hole that penetrates the rotating housing and communicates with the outside, for draining accumulated water.

[0008] The present invention is further configured such that: a main circuit is provided inside the housing, and three secondary circuits are provided inside the rotating housing respectively connected to different functional modules. A passage connection structure is provided between the main circuit and each secondary circuit. The passage connection structure includes a rotating hole provided on the housing, a cylinder rotatably provided on the rotating hole and on the rotating housing, and a wire through hole provided through the cylinder. The connecting wires of the three secondary circuits all pass through the wire through hole and are connected to the main circuit.

[0009] The present invention is further configured such that: the passage connection structure further includes a limiting structure for limiting the rotation angle of the rotating housing on the housing, the limiting structure including a rotating platform disposed on the cylinder, a rotating protrusion disposed on the rotating platform, and two stops disposed on opposite inner walls on both sides of the main housing, the two stops being disposed at both ends of the rotation path of the rotating protrusion, the limiting structure being configured such that the rotating shaft formed between the rotating platform and the rotating housing is placed in the rotating hole to form rotation of the rotating housing, and the stops on both sides form a block when the rotating housing rotates to the corresponding position.

[0010] This application also provides a control method for a cigarette lighter with a lighting function, the control method comprising the following steps: S1. Rotational Force Detection: During the rotation of the rotating housing, a force detection element installed between the housing and the rotating housing detects the rotational operating force acting on the rotating housing in real time and sends the detected force signal to the control module; the control module determines the type of rotational operation based on the force signal. S2. Rotation positioning: Rotate the rotating housing so that the positioning beads in the elastic positioning component are sequentially inserted into the corresponding positioning grooves under the abutment of the elastic element, forming multi-position positioning, so that one of the A, B or C sides of the rotating housing faces away from the front of the housing, and lock the current rotation angle. S3. Function Recognition: The control module identifies the function module currently facing away from the front of the housing and supplies power to the corresponding function module based on the recognition result, putting the function module into standby mode. S4. Function Start / Stop: By using the control button on the housing, a start signal or stop signal is sent to the control module. The control module controls the function module to start or stop working based on the currently identified function module. S5. Function Adjustment: When the function module is in the start state, an adjustment signal is sent to the control module through the control button, and the control module adjusts the working parameters of the current working module according to the adjustment signal; In step S1, the rotation operation force is set to N, the first preset value is R1, and the second preset value is R2. If the control module determines that N < R1, the control module ignores the current rotation operation and does not execute any switching action in steps S1 to S4. If N > R2 and continues to act on the rotating housing for more than a preset time, the control module determines it to be a fast switching operation and directly controls the rotating housing to skip the intermediate position and jump to the next adjacent functional module facing away from the front of the housing.

[0011] The beneficial effects of this invention are: 1. The rotating housing design integrates the cigarette lighter, flashlight, and reading modules into a single unit, meeting multiple needs in a single scenario. This significantly improves product practicality and convenience, eliminating the need for users to carry multiple devices. The rotating housing maintains a continuous power supply to all modules regardless of the rotation mode, preventing power outages during mode switching and ensuring normal operation. The control module allows for the use of different module functions, enabling users to easily and quickly select the desired function based on their needs, offering simple and efficient operation. The elastic positioning component in the damped rotating positioning structure works in conjunction with the positioning groove. As the rotating housing rotates, the positioning beads sequentially engage with the positioning groove, forming multi-position positioning. This ensures precise and stable positioning of the rotating housing in each functional mode, preventing functional mode errors caused by accidental rotation.

[0012] 2. The elastic sealing ring forms a sealed contact at the joint between the rotating housing and the main housing, preventing external moisture and dust from entering the cigarette lighter's interior. This protects the internal lighting components, power supply, and control module, preventing short circuits and malfunctions caused by moisture or dust accumulation, thus extending the cigarette lighter's lifespan. The sealed structure reduces the corrosive effects of external environmental factors on internal components, minimizing wear and tear caused by environmental factors. This allows the cigarette lighter to operate normally in various complex environments, improving overall product durability and reducing maintenance and replacement costs. If a small amount of water accidentally enters the sealed structure, the drainage holes can promptly drain the water to the outside, preventing water accumulation in the sealing groove and further ensuring that internal components are not damaged by prolonged immersion in water.

[0013] 3. Through the cooperation of the rotating hole and the cylinder, the rotating housing can rotate flexibly relative to the main housing. Simultaneously, the wire perforations on the cylinder ensure the stable connection of the wires between the secondary and main circuits. Even when the housing rotates, the circuit connection is not affected, achieving smooth circuit connection when different functional modules switch, ensuring the normal operation of each function. The wires connecting each secondary circuit to the main circuit through the wire perforations keep the internal wiring neat and orderly, avoiding tangled wires and reducing the risk of short circuits and other faults caused by wire tangling. This facilitates later maintenance and repair, improving the reliability and stability of the product.

[0014] 4. Clearly define the rotation angle range of the rotating housing to prevent excessive rotation from causing internal wiring distortion or damage. Ensure that the rotating housing accurately stops at the preset position with each rotation, allowing for precise switching between functional modules and providing users with a stable and reliable operating experience. Avoid excessive stretching or tangling of the wires connecting the main and auxiliary circuits due to unrestricted rotation of the housing, extending wire lifespan, reducing the possibility of malfunctions caused by wiring problems, and ensuring the long-term stable operation of the cigarette lighter electrical system.

[0016] Reference Figure 1-4 The embodiments of the present invention will be further described below.

[0017] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0018] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0019] Figures 1 to 4 The cigarette lighter with lighting function shown includes a housing 1 and a cigarette lighter assembly disposed within the housing 1. The cigarette lighter assembly includes a rotating housing 2 disposed on and rotatably connected to the housing 1, a cigarette lighter module 3 disposed on surface A of the rotating housing 2, a flashlight module 4 disposed on surface B of the rotating housing 2, a reading module 5 disposed on surface C of the rotating housing 2, a power supply 6 disposed within the housing 1 and electrically connected to each module, and a control module 7 disposed within the housing 1. The rotating housing 2 is configured to form a rotatable connection with the housing 1 and maintain a continuous path with the power supply 6. Through the control module 7 disposed within the housing 1, the simultaneous use of the practical functions of different modules can be realized. A damped rotation positioning structure is also provided between the housing 1 and the rotating housing 2. The damped rotation positioning structure includes an elastic positioning component disposed between the housing 1 and the rotating housing 2 and a plurality of positioning grooves 8 disposed on the rotating housing 2. The elastic positioning component includes a positioning bead 9 and an elastic element 10 abutting against the positioning bead 9. The positioning bead 9 is configured to sequentially engage with each positioning groove 8 when the rotating housing 2 rotates to form a multi-position positioning.

[0020] The rotating housing 2 integrates the cigarette lighter module 3, flashlight module 4, and reading module 5 into a single unit, meeting the needs of multiple scenarios with just one device. This greatly improves the product's practicality and convenience, eliminating the need for users to carry multiple devices. The rotating housing 2 is rotatably connected to the housing 1 and maintains a continuous power supply to the battery 6. Regardless of the rotation mode, it ensures stable power supply to each module, preventing power outages during mode switching and guaranteeing normal functionality. The control module 7 enables the use of different module functions, allowing users to conveniently and quickly select the desired function based on their actual needs, making operation simple and efficient. The elastic positioning component in the damped rotary positioning structure cooperates with the positioning groove 8. As the rotating housing 2 rotates, the positioning beads 9 sequentially engage with the positioning groove 8, forming multi-position positioning. This ensures that the rotating housing 2 can be accurately positioned and stably maintained in each functional mode, preventing functional mode errors caused by accidental rotation.

[0021] The rotating housing 2 is equipped with an elastic sealing structure located at the junction of the rotating housing 2 and the housing 1. This structure prevents external moisture and dust from entering the cigarette lighter, protecting the internal precision components such as the cigarette lighter assembly, the power supply 6, and the control module 7. It also prevents short circuits and malfunctions caused by moisture or dust accumulation, extending the cigarette lighter's service life. The structure includes an annular sealing groove 11 embedded in the end face of the rotating housing 2 and an elastic sealing ring 12 within the annular sealing groove 11. The elastic sealing ring 12 is configured to form a sealing contact when the rotating housing 2 and the housing 1 are joined. This sealing structure reduces the erosion of internal components by external environmental factors, lowers losses caused by environmental influences, and enables the cigarette lighter to operate normally in various complex environments, improving the overall durability of the product and reducing maintenance and replacement costs.

[0022] The bottom of the annular sealing groove 11 is provided with a guide hole 13 that penetrates the rotating housing 2 and communicates with the outside. When a small amount of water accidentally enters the sealing structure, the guide hole 13 can discharge the water to the outside in time, preventing water from accumulating in the sealing groove and further ensuring that the internal components will not be damaged due to long-term immersion in water.

[0023] The housing 1 houses a main circuit, while the rotating housing 2 houses three secondary circuits, each connecting to a different functional module. A connection structure connects the main circuit and each secondary circuit. This connection structure includes a rotating hole 14 on the housing 1, a cylinder 15 rotatably mounted on the rotating hole 14 and on the rotating housing 2, and a through-hole 16 for wires passing through the cylinder 15. Through the interaction of the rotating hole 14 and the cylinder 15, the rotating housing 2 can rotate flexibly relative to the housing 1. Simultaneously, the through-hole 16 on the cylinder 15 ensures the stable connection of the wires between the secondary and main circuits. Even when the rotating housing 2 rotates, the circuit connection remains unaffected, ensuring smooth circuit connectivity during rotational switching between different functional modules and guaranteeing normal operation of each function. The wires connecting each secondary circuit to the main circuit via the through-hole 16 maintain neat and orderly internal wiring, preventing tangled wires and reducing the risk of short circuits caused by wire tangling. This facilitates later maintenance and repair, improving the product's reliability and stability.

[0024] The passage connection structure also includes a limiting structure for restricting the rotation angle of the rotating housing 2 on the housing 1. This limiting structure includes a rotating platform 17 mounted on the cylinder 15, a rotating protrusion 18 mounted on the rotating platform 17, and two stops 19 respectively mounted on opposite inner walls on both sides of the main housing 1. The two stops 19 are respectively located at both ends of the rotation path of the rotating protrusion 18. The limiting structure is configured such that the rotating shaft 20 formed between the rotating platform 17 and the rotating housing 2 is placed within the rotating hole 14 to rotate the rotating housing 2, and the stops 19 on both sides block the rotating housing 2 when it rotates to the corresponding position. This clearly limits the rotation angle range of the rotating housing 2, preventing excessive rotation that could cause internal circuit distortion or damage, ensuring that the rotating housing 2 accurately stops at a preset position each time it rotates, allowing for accurate switching of functional modules and providing users with a stable and reliable operating experience. It also avoids excessive stretching or tangling of the wires connecting the main and auxiliary circuits due to unrestricted rotation of the rotating housing 2, extending the lifespan of the wires, reducing the possibility of malfunctions caused by wiring problems, and ensuring the long-term stable operation of the cigarette lighter electrical system.

[0025] This application also provides a control method for a cigarette lighter with a lighting function, the control method comprising the following steps: S1. Rotational force detection: During the rotation of the rotating housing 2, the rotational operating force acting on the rotating housing 2 is detected in real time by a force detection element set between the housing 1 and the rotating housing 2, and the detected force signal is sent to the control module 7; the control module 7 determines the type of rotational operation based on the force signal. S2. Rotation positioning: Rotate the rotating housing 2 so that the positioning beads 9 in the elastic positioning component are sequentially inserted into the corresponding positioning grooves 8 under the abutment of the elastic element 10, forming a multi-position positioning, so that one of the A, B or C sides of the rotating housing 2 faces away from the front of the housing 1, and locks the current rotation angle. S3. Function Recognition: The control module 7 identifies the function module currently facing away from the front of the housing 1, and supplies power to the corresponding function module according to the recognition result, putting the function module into standby mode. S4. Function start / stop: By using the control button on the housing 1, a start signal or stop signal is sent to the control module 7. The control module 7 controls the function module to start or stop working according to the currently identified function module. S5. Function Adjustment: When the function module is in the start state, an adjustment signal is sent to the control module 7 through the control button. The control module 7 adjusts the working parameters of the current working module according to the adjustment signal. In step S1, the rotational operating force is set to N, the first preset value is R1, and the second preset value is R2. If the control module 7 determines that N < R1, then the control module 7 ignores the current rotational operation and does not execute any switching action in steps S1 to S4. If N > R2 and continues to act on the rotating housing 2 for more than a preset time, then the control module 7 determines it to be a rapid switching operation and directly controls the rotating housing 2 to skip the intermediate gear and jump to the next adjacent functional module facing away from the front of the housing 1.

[0026] The rotational force detection element detects the rotational operating force to determine the operation type, and the elastic positioning component realizes multi-level positioning. The control module 7 identifies the function module and supplies power. The user can start, stop and adjust the function through the control button. When the rotational force is greater than a certain value and lasts for a certain period of time, the function can be quickly switched. It has the beneficial effects of accurate identification, clear positioning, intelligent power supply, convenient and efficient operation.

[0027] The positioning beads 9 of the damping rotary positioning structure are sequentially inserted into the positioning grooves 8 when the rotating housing 2 rotates to form multi-position positioning, and the damping rotary positioning structure is implemented within the rotatable angle range of the rotating protrusion 18 and the stop 19.

Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included within the protection scope of the present invention.
