[0044] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.
[0045] like Figure 1-10 As shown, this utility model provides an outdoor lighting device, including a base 1, a combustion chamber 2, a rotating component 3, and a fuel guide 3.1. The base 1 is provided with a fuel chamber 1.1, and a guide groove 1.2 is vertically formed above the fuel chamber 1.1. The guide groove 1.2 can be composed of a square tube that passes through the fuel chamber 1.1. The combustion chamber 2 is located above the base 1, covering the upper end of the guide groove 1.2, and is horizontally arranged within the guide groove 1.2 and can rotate. The fuel guide 3.1 is wound around the rotating component 3, with one end extending into the combustion chamber 2 and the other end extending into the guide groove 1.2, for drawing fuel out of the fuel chamber 1.1. By rotating the rotating component 3, the other end of the guide component 3.1 can be wound or released. Under the guidance of the guide groove 1.2, the guide component 3.1 moves vertically to adjust its height, thereby adjusting the exposed area of the guide component 3.1, i.e., the amount of fuel-air contact. A larger exposed area results in greater air contact, which can improve combustion efficiency; a smaller exposed area results in less air contact, which can reduce combustion efficiency to meet the requirements of prolonged combustion. The combustion chamber 2 is provided with multiple openable and closable doors 4. The combustion chamber 2 can be opened or closed by opening and closing the doors 4 to perform operations such as ignition and maintenance of the guide component 3.1 in the guide groove 1.2. Preferably, the doors 4 can be hollow or made of transparent material to facilitate light exposure.
[0046] The base 1 is provided with a perforated plate 5 around the guide groove 1.2. A straight support 6 is provided at the upper end of the perforated plate 5. The support 6 is set below the upper opening of the guide groove 1.2, and the support 6 has multiple air holes 6.1 parallel to the guide groove 1.2.
[0047] After the above improvements, outside air enters the outside of the guide groove 1.2 through the perforated plate 5, and then enters the upper opening of the guide groove 1.2 through the air hole 6.1. When the fuel guided by the guide element 3.1 at the upper opening of the guide groove 1.2 is burning, air can be drawn upward. The airflow quickly passes through and enters the combustion chamber 2, providing sufficient air in the combustion chamber 2 and at the upper opening of the guide groove 1.2 to improve the combustion effect. At the same time, the airflow is not directly blown towards the ignition point of the guide element 3.1, which can avoid the problem of direct airflow causing the flame to go out.
[0048] The bottom of the combustion chamber 2 is hinged to the support 6 via a hinge structure. The hinge structure includes a limiting part 7 and a connecting part 8. The limiting part 7 is located at the upper rear part of the support 6 and extends rearward. The connecting part 8 is located at the lower rear part of the fuel chamber 1.1. The connecting part 8 is provided with a connecting groove 8.1. The connecting part 8 first extends rearward and then bends downward. The limiting part 7 passes through the vertical section of the connecting groove 8.1. When the combustion chamber 2 rotates rearward, the connecting groove 8.1 moves relative to the limiting part 7 to the horizontal section and cooperates with the limiting part 7, so that the combustion chamber 2 is kept in the position where the upper end of the guide groove 1.2 is exposed, while preventing the combustion chamber 2 from rotating excessively.
[0049] When the combustion chamber 2 rotates forward, the connecting groove 8.1 moves relative to the limiting part 7 to the vertical section and cooperates with the limiting part 7, so that the combustion chamber 2 can continue to rotate forward to the position where the upper end of the guide groove 1.2 is covered inside. At this time, it can play a protective role and effectively prevent the combustion from going out.
[0050] The bottom front end of the combustion chamber 2 extends downward to form a fixed seat 9. A positioning seat 10 is provided at the corresponding position of the bracket 6. When the combustion chamber 2 is in the position where the upper end of the guide groove 1.2 is covered inside, the front end face of the positioning seat 10 abuts against the rear end face of the fixed seat 9 to initially position the combustion chamber 2, making its position relatively stable and preventing it from easily tipping over. The fixed seat 9 is provided with a through hole 9.1, and the positioning seat 10 is provided with a connecting hole at the corresponding position. When the front end face of the positioning seat 10 abuts against the rear end face of the fixed seat 9, the through hole 9.1 and the connecting hole are positioned opposite each other, and a threaded connector 11 can be inserted into the through hole 9.1 and the connecting hole to fix the combustion chamber 2.
[0051] One end of the rotating component 3 passes through the guide groove 1.2 to the outside of the perforated plate 5 and is equipped with a knob 3.2. The user operates the rotating component 3 to rotate it via the knob 3.2, which is convenient to use. A radially extending pin 3.3 is provided on the knob 3.2, and the guide component 3.1 is made of cotton core. The cotton core is wrapped around the head of the pin 3.3, and the head of the pin 3.3 can be embedded in the cotton core to increase the stability of the connection. When the rotating component 3 rotates, the cotton core can be stably gathered or released. A shelf 13 is provided above the combustion chamber 2. The shelf 13 can be used by the user to place items such as water cups and other utensils. The heat generated by combustion can be used to heat the items for user convenience. The combustion chamber 2 is rotatably connected to a handle 14. The handle 14 can be unfolded above the combustion chamber 2 or folded to a position close to the combustion chamber 2. When in use, the device can be lifted by the handle 14 for further convenience. The fuel chamber 1.1 is located inside the hollow base 1, and the base 1 is also provided with an injection port 15 that communicates with the fuel chamber 1.1.
[0052] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
