[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment

[0024] Please refer to Figures 1-7 , as shown in the figure, a flame outlet direction adjusting mechanism of a lighter is shown, which includes a rotating head 1 and a main housing 2. The rotating head 1 has an air outlet, and the main housing 2 has a fuel storage part and a pressing ignition part. These are all prior arts and will not be elaborated in detail here. A upper connecting member 3 is clamped or fixedly connected to the rotating head 1, and a lower connecting member 4 is clamped or fixedly connected to the main housing 2. Both the upper connecting member 3 and the lower connecting member 4 are of hollow structure, and this hollow structure is for the space for air outlet and for the ignition needle to pass through. One end of the upper connecting member 3 is provided with a connecting portion 31 passing through the lower connecting member 4; or one end of the lower connecting member 4 is provided with a connecting portion 31 passing through the upper connecting member 3; a locking member 8 is connected to the connecting portion 31, and an angle positioning mechanism is provided between the lower surface of the upper connecting member 3 and the upper surface of the lower connecting member 4. In this embodiment, the angle positioning mechanism specifically includes annularly distributed pits 5 provided on the lower surface of the upper connecting member 3 or the upper surface of the lower connecting member 4, and at least one convex 6 that can be engaged in the pits 5 is provided on the other surface. The cooperation of the convex 6 and the pits 5 provided at the end face in this embodiment has stronger anti-load capacity compared with the clamping cooperation provided at the periphery. For example, when the upper and lower connecting members 4 adopt radial positioning, a relatively large space needs to be reserved in the radial direction of the upper and lower connecting members 4, which makes its strength lower. In addition, an elastic mechanism needs to be provided, further compressing this space, making the strength of the upper and lower connecting members 4 even lower. If you want to increase the strength, then only the part size can be made larger, which will make the size of the entire lighter need to be made larger, increasing a large amount of cost and also affecting the portability of the product.

[0025] In order to keep the positioning between the upper and lower connecting members 4 at a set position and not be accidentally rotated, this embodiment also provides an elastic member 7 that drives the convex 6 and the pits 5 to maintain a clamping fit in the normal state, and the elastic member 7 applies an axial top force to the upper connecting member 3 or the lower connecting member 4. A step structure 41 facing the locking member 8 is provided in the hollow part of the lower connecting member 4. The elastic member 7 is provided between the step structure and the locking member 8, and one end of the elastic member 7 abuts against the locking member 8, and the other end abuts against the step surface of the lower connecting member 4. The elastic member 7 in this embodiment is a spring.

[0026] In this embodiment, after the lower connecting member is installed on the main housing, the upper end of the lower connecting member protrudes from the main housing. The rotating head is movably sleeved on the lower connecting member at the protruding portion 43. A concave recess 44 is provided at the end of the protruding portion. The upper connecting member has a frustum portion 34 inserted into the recess portion. The frustum portion cooperates with the protruding portion of the lower connecting member to prevent the rotating head from shaking when rotating relative to the main housing. And this part further strengthens the connection strength of the product.

[0027] In this embodiment, in order to prevent slipping between the upper connecting member 3 and the rotating head 1, and between the lower connecting member 4 and the main housing 2, the upper connecting member 3 has a radially extending upper edge 33, and the rotating head 1 is provided with an upper clamping position 11 for the upper edge of the upper connecting member 3 to be inserted. When the upper connecting member 3 is connected to the rotating head 1, it is clamped in the upper clamping position, and an anti-rotation structure is provided between the upper edge and the upper clamping position; the lower connecting member 4 has a radially extending lower edge 42, and the main housing 2 is provided with a lower clamping position 21 for the lower edge of the lower connecting member 4 to be inserted. When the lower connecting member 4 is connected to the main housing 2, it is clamped in the lower clamping position, and an anti-rotation structure is provided between the lower edge and the lower clamping position.

[0028] In this embodiment, the anti-rotation structure includes designing the upper edge and / or the lower edge as non-circular shapes, and the corresponding upper clamping position and / or lower clamping position are designed to match the shapes of the upper edge and / or the lower edge. The non-circular shape can be an oval, a square, a trapezoid, a D-shaped or other irregular shapes. The anti-rotation structure can also be radially provided with protrusions on the circular upper edge or lower edge, and grooves for the protrusions to be inserted are provided on the corresponding rotating head and main housing.

[0029] The connecting portion 31 at the lower end of the upper connecting member 3 has a cap portion 32 or a card slot, and the locking member 8 is connected in the cap portion 32 or the card slot. In this embodiment, it is the cap portion 32. The diameter of the cap portion 32 is larger than other positions of the connecting portion 31, and a step is formed between the cap portion 32 and other positions of the connecting portion 31. The locking member 8 is abutted by a spring at the step. The outer wall of the cap portion 32 is a conical structure with a smaller diameter at the lower end and a larger diameter at the upper end. Both the locking member 8 and the upper connecting member 3 are made of plastic. When installing, the locking member 8 is forced to cross the step and is sleeved on the connecting portion 31 of the upper connecting member 3. Since both the locking member 8 and the upper connecting member 3 are plastic parts, they both have good deformation amounts. Therefore, the locking member 8 can be forced to cross the cap portion 32 and be sleeved on the connecting portion 31 of the upper connecting member 3.
