Description

Technical field of the invention

[0001] The present invention relates to the technical field of pre-filter programs and in particular to a wick structure for oil lamps. State of the art

[0002] In modern everyday life, electric lamps are predominantly used. However, people still resort to traditional oil lamps for certain traditional festivals or special occasions. When using oil lamps, a wick is required. Conventional simple wicks run the risk of oil leakage. Therefore, leak-proof wicks have been developed. However, this type of wick has deficiencies during installation and use. Such wicks are usually attached to the oil bottle using a swivel connection. However, the swivel connection can easily be overtightened, which can lead to damage to the threaded hole of the oil bottle and the threaded section of the wick. This also makes subsequent removal and refilling of oil inconvenient, which significantly shortens the lifespan of the product. Therefore, further improvement is needed. Object of the invention

[0003] The invention is based on the object of avoiding the above-mentioned disadvantages and providing a wick structure for oil lamps.

[0004] To achieve the above-mentioned object, the present invention uses the following technical solutions: A wick structure for oil lamps comprises a lamp cover and a lamp rod, wherein the lamp rod is provided with a threaded portion and a wick hole is provided in the lamp rod, wherein the lamp cover comprises a cover shell and a cover base, the cover shell is fixedly connected to the cover base, the cover base is provided with a connecting hole, one end of the lamp rod is connected to the cover base in a position-determining manner and the two are rotatable relative to each other, wherein an abutment projection is provided on the lamp rod, a spring is arranged on the lamp rod, the two ends of the spring respectively abut against the abutment projection and cover base, and the lamp rod and the cover base abut against each other due to the elastic force of the spring.

[0005] In the wick structure, the end of the lamp rod connected to the connecting hole is provided with a locking groove in which an elastic C-ring is arranged.

[0006] In the wick structure, a contact step is provided in the connecting hole, with the ends of the spring resting on the contact step.

[0007] In the wick structure, the spring is located in the connecting hole.

[0008] In the wick structure, the end of the connecting bore corresponding to the contact projection is provided with a receiving recess, wherein the contact projection is movable in the receiving recess.

[0009] The advantageous effects of the present invention: The present invention utilizes the elastic force of the spring to achieve engagement between the lamp rod and the lamp cover. When the present invention is connected to an oil bottle, the lamp rod is connected to the oil bottle by rotating the lamp cover and the elastic engagement between the lamp cover and the lamp rod. After the rotary connection is tightened, the elastic force of the spring between the lamp rod and the lamp cover is overcome, allowing relative rotation between the two. This prevents damage caused by over-rotation at the rotary connection and facilitates subsequent oil removal and refilling. Brief description of the drawings Fig. 1 shows a perspective view according to the present invention; Fig. Fig. 2 shows a sectional view according to the present invention; Fig. 3 shows an exploded view according to the present invention. Detailed description of the preferred embodiment

[0010] The present innovation is explained in more detail below with reference to the attached drawings.

[0011] It will be on the Fig. 1 to 3. The present invention provides a wick structure for oil lamps comprising a lamp cover 1 and a lamp rod 2, wherein the lamp rod 2 is provided with a threaded portion 3 and a wick hole 4 is provided in the lamp rod 2 for passing the wick therethrough.

[0012] The lamp cover 1 comprises a cover shell 5 and a cover base 6. The cover shell 5 is firmly connected to the cover base 6, the cover base 1 is provided with a connecting hole 7, one end of the lamp rod 2 is connected to the cover base 6 in a position-determining manner, and the two are rotatable relative to each other. More specifically, the end of the lamp rod 2 connected to the connecting hole 7 is provided with a locking groove 10 in which an elastic C-ring 11 is arranged.

[0013] A contact projection 8 is provided on the lamp rod 2. A spring 9 is arranged on the lamp rod 2, wherein the spring 9 is located in the connecting hole 7 and the two ends of the spring 9 each abut against the contact projection 8 and the cover base 6, so that the lamp rod 2 and the cover base abut each other due to the elastic force of the spring 9.

[0014] A contact step 12 is provided in the connecting bore 7, with the ends of the spring 9 resting against the contact step 12. This design ensures that the spring 9 is completely located within the cover base 6, thereby reducing the required height and enabling an aesthetically pleasing fit for more types of oil bottles.

[0015] The end of the connecting bore 7 corresponding to the contact projection 8 is provided with a receiving recess 13, wherein the contact projection 8 is movable in the receiving recess 13. By compressing the spring, the contact projection rests against the receiving recess.

[0016] When connecting the wick to an oil bottle, the cover shell 5 is firmly connected to the cover base 6. Since the lamp rod 2 and the cover base 6 abut each other due to the elastic force of the spring, rotating the lamp cover 1 and the elastic force can drive the lamp rod 2 to rotate, thereby rotatably connecting the threaded portion 3 of the lamp rod 2 to the oil bottle. After the rotary connection is tightened, the elastic contact between the lamp rod 2 and the lamp cover 1 is overcome by the fastening between the lamp rod 2 and the oil bottle, so that relative rotation occurs between the two. With continued rotation, the lamp rod 2 and the lamp cover 1 rotate relative to each other, thus preventing damage caused by over-rotation at the rotary connection and facilitating subsequent removal and refilling of oil.During the rotation process, pressure can also be applied to the lamp cover to compress the spring so that the cover base of the lamp cover rests on the contact projection of the lamp rod and thus the rotation speed is accelerated.
