Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and to provide a switching mechanism of a rotating double-flame lighter based on a grinding wheel driving wheel and a lighter.

[0006] A switching mechanism of a double-flame lighter based on the rotation of a grinding wheel driving wheel, the double-flame lighter includes an air box, a first flame generating head, a second flame generating head, a first air pipe connecting the air box and the first flame generating head, a second air pipe connecting the air box and the second flame generating head, and also includes a grinding wheel ignition unit, the grinding wheel ignition unit includes a rotatable grinding wheel and a driving wheel coaxially rotating with the grinding wheel, the switching mechanism includes a switching block, the switching block and the driving shaft are axially slidingly matched; when the driving shaft is located at a first axial position, the switching block and the first air pipe form an air path release match, and when the driving shaft is located at a second axial position, the switching block and the first air pipe form an air path cut-off match.

[0007] Through the above technical solution, the lighter can realize the switching of two flame states. In the first position, due to the high air pressure in the first air pipe, when the driving wheel is rotated, the grinding wheel directly starts the first flame generating head to ignite. When direct ignition is required, the axially movable driving wheel uses the trigger part to drive the switching block to move, the air path of the first air pipe is cut off, the switching block moves from the first position to the second position, and the driving wheel is rotated again to perform direct ignition.

[0008] Preferably, the switching mechanism also includes a fixed seat, the switching block is slidably set on the fixed seat, the switching block is provided with a first through hole, and the fixed seat is provided with a second through hole. When the switching block driving shaft is in the first position, the first through hole and the second through hole have at least a portion of overlapping areas, and the overlapping portion of the area constitutes an air pipe installation passage for the first air pipe to pass through and release gas.

[0009] Through the above technical solution, the size and position of the first through hole and the second through hole can be flexibly adjusted, and the shapes can also be different. It is only necessary to pass the first air pipe through to release the gas. When in use, the gap between the first through hole and the second through hole can be contracted to cut off the gas path.

[0010] Furthermore, the overlap of the partial area is a complete overlap, and the shape and size of the first through hole and the second through hole are both compatible with the first air pipe. Preferably, the first through hole and the second through hole are compatible with the first air pipe, which is convenient for fixing the position of the first air pipe, and is convenient for operation and installation.

[0011] Preferably, the switching block is provided with a first spring for driving the switching block to return from the second position to the first position.

[0012] Through the above technical solution, after the switching is completed, the switching block can be reset to the original position by the elastic force of the first spring, and the first flame generating head can be used again for ignition. The practical value of the lighter is improved and meets various needs of users. It has a simple structure, convenient operation, fast switching and convenient use. At the same time, the use of grinding wheel rotation as a power source is safer, more stable and reliable than other traditional lighter ignition methods. The lighter has high market competitiveness and application value.

[0013] Preferably, the fixing seat is fixed on the middle frame, a fixing column is provided on the top of the switching block, a fixing groove is provided on the middle frame, one end of the first spring is clamped in the fixing groove, and the other end is sleeved on the fixing column.

[0014] Through the above technical solution, the design of the fixing seat and the fixing column, the middle frame and the fixing groove, and the first spring is conducive to the stable fixing and motion control of the switching block, ensuring that the lighter will not loosen or shake during the switching of the two ignition states and the continuous ignition, and has a stable reset function. In addition, the setting of the fixing column and the fixing groove also facilitates the installation and adjustment of the first spring, which is conducive to maintaining the appropriate tension of the spring, and further improves the reliability and durability of the lighter.

[0015] Preferably, a mounting groove is provided in the fixing seat, and one end of the switching block extends into the mounting groove and is slidably connected thereto.

[0016] Through the above technical solution, a mounting groove is provided in the fixing seat, and one end of the switching block extends into the mounting groove and is connected to the fixing seat through a sliding connection. This design makes the switching block and the fixing seat have high stability, reliability and shock resistance, and can effectively resist the influence of various external forces that occur during use, thereby ensuring that the lighter can stably switch between the two ignition states under any circumstances. At the same time, the presence of the mounting groove can also facilitate various maintenance and care of the switching block, ensuring a longer service life of the lighter and extending its service life. This design can improve the reliability and stability of the lighter, further improve the accuracy of the switching, and ensure the user experience and safety.

[0017] Preferably, the driving wheel includes a mounting shaft, a reset cavity surrounding the mounting shaft is provided in the driving wheel, the mounting shaft includes a limiting portion and a clamping portion clamped with the driving wheel, a second spring sleeved outside the clamping portion is provided in the reset cavity, one end of the second spring abuts against the driving wheel, and the other end abuts against the limiting portion.

[0018] Through the above technical solution, the design of the driving wheel has excellent reset function and control performance. A reset cavity surrounding the mounting shaft is provided in the driving wheel, and a second spring is provided. The spring can receive the corresponding force, so that the driving wheel can be elastically reset to control the lighter to return from the ignition state of the first flame generating head to the ignition state of the second flame generating head. At the same time, the setting of the limit part can also limit the movement range of the driving wheel to avoid the malfunction of the lighter due to the driving wheel moving beyond the range. This design can ensure that the lighter can stably and reliably complete the switching between the open flame and direct charge states during normal use, thereby improving the accuracy and stability of the lighter.

[0019] The utility model also provides a double-flame lighter, which uses the switching mechanism to perform ignition, wherein the first flame generating head is an open flame ignition head, and the second flame generating head is a direct impingement ignition head.

[0020] Through the above technical solution, the types of the first flame generating head and the second flame generating head can be flexibly selected, preferably an open flame ignition head and a direct impingement ignition head.

[0021] Preferably, the first flame generating head is provided with at least two flame outlets, one of which is arranged toward the direction of the second flame generating head.

[0022] Through the above technical solution, one of the fire outlets is set toward the second flame head, so that the air pressure of the first flame head is greater than that of the second flame head. When the first flame head is used, the second flame head will not ignite due to the difference in air pressure, thereby ensuring the switching function between the open flame and the direct-injection state. This helps to further enhance the practicality and convenience of the lighter and improve the user experience and satisfaction.

[0023] Furthermore, it comprises an air box, on which an air valve and a pry plate for driving the air valve to open and close are arranged, and on the middle frame there is a flap connected to the pry plate.

[0024] Through the above technical scheme, the air box is provided with an air valve and a pry plate for opening and closing the driving air valve, and the first air pipe and the second air pipe are both arranged on the air valve, and the air valve can effectively regulate the flow of airflow and control the in and out of gas, thereby realizing the control and adjustment of the air valve inside the lighter; the pry plate driving the air valve can conveniently open and close the air valve, realize the release and sealing of gas more quickly, and achieve the effect of rapid ignition or stoppage; the first air pipe and the second air pipe are arranged on the air valve, so that the transmission of airflow is smoother and more efficient, and the ignition speed and responsiveness of the lighter are improved; the design of the air valve and the air pipe can ensure that the lighter generates flames quickly and stably during operation, and improves the working efficiency and practicality of the lighter; effectively optimizes the airflow control of the lighter, making it more convenient, safe, and stable to ignite or stoppage, and improves the user experience and safety. The second flame generating head adopts a straight-into-the-pagoda. After flipping the cover, the driving wheel can be rotated to ignite, and the first air pipe and the second air pipe continuously supply gas for open flame ignition or direct-into-the-pagoda ignition.

[0025] The beneficial effects of the utility model are as follows: the lighter can realize the switching of two flame states. In the first position, due to the high air pressure in the first air pipe, when the driving wheel is rotated, the grinding wheel directly starts the first flame generating head to ignite. When direct ignition is required, the axially movable driving wheel drives the switching block to move by the trigger part, the air path of the first air pipe is cut off, the switching block moves from the first position to the second position, and the driving wheel is rotated again to perform direct ignition.
