CROSS-REFERENCE TO RELATED APPLICATIONS

The present disclosure claims priority to Chinese Patent Application No. 202021263355.7, filed with the Chinese Patent Office on Jun. 30, 2020, titled “PROTECTIVE DEVICE AND CANDLE WICK BURNING LAMP ASSEMBLY”, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

Embodiments of the present disclosure relate to the technical field of lighting technologies, and in particular, relate to a protective device and a candle wick burning lamp assembly.

BACKGROUND

Candle wick burning lamps are widely used in backup illumination after power interruption, and some special atmosphere creation scenarios.

Generally, a candle wick burning lamp includes a container and a candle wick structure. The container includes a bottom and a side wall surrounding the bottom. The candle wick structure includes a candle wick body and a support base fixed with one end of the candle wick body. The support base is fixed by adhesive to the bottom of the container. The candle wick body is surrounded by the side wall of the container.

However, during use of the above candle wick burning lamp, especially in the event of exhaust of the candle wick body, the heat produced by burning may melt the adhesive for fixing the support base. As a result, it is hard to retain the support base at a predetermined position of the bottom of the container. For example, the support base would be close to the side wall of the container, and a burning end of the candle wick body approaches or even contacts the side wall of the container, such that the burning of the candle wick body is affected, or even the container is broken due to uneven heating, which may result in dangers. One solution is to press the support base with a circular iron cover and let the candle wick body go through holes at the proper position of the circular iron cover. However, the circular iron cover wastes materials, and the weight of such a product is greatly increased. Additionally the circular iron cover is not convenient to install or take out.

Referring toFIG. 7andFIG. 8, a protective device20according to an embodiment of the present disclosure is illustrated. The protective device20is configured to be used with the candle wick burning lamp10as described above.

The protective device20is placed at the bottom120of the container, and the protective device20and the side wall122of the container are on the same side of the bottom120of the container, such that the support base142is fixed to the predetermined position of the bottom120of the container.

The protective device20may be made by stamping metal thin sheets, and is substantially in a sheet-like structure. The protective device20includes a central portion22and a branch portion24. The branch portion24and the central portion22are integrally formed. The branch portion24is in a stripe shape, and one end of the branch portion is connected to the central portion22. A length L of the branch portion24is substantially equal to a diameter d/2 of the circular structure, that is, the length L of the branch portion24is substantially equal to a radius of the circular structure.

A through hole240is opened at a middle waist position of the branch portion24. A radius r of the through hole240is 1 to 1.5 times a radius of the candle wick body140, which conveniently allows the candle wick body140to pass through the through hole240, and better restrains the support base142to the predetermined position of the bottom120of the container.

It may be understood that according to the actual needs, a radius r of the through hole240may be defined to any value as long as the candle wick body140is allowed to pass therethrough.

A width D of the branch portion is 2 to 4 times the radius r of the through hole240, such that it may be ensured that the branch portion24has a small size and has a sufficient strength, and hence the middle waist may be not easily subject to fracture due to the through hole240arranged in the middle waist position.

It may be understood that according to the actual needs, the width D of the branch portion24and the radius of the through hole240may be defined to any value as long as the through hole240is arranged in the middle waist position of the branch portion24.

The number of branch portions24may be two. The two branch portions24are arranged in a fashion of surrounding the central portion22, and define a 180-degree angle therebetween. The through holes of the two branch portions24are respectively passed through by two candle wick bodies140. It should be noted that this embodiment is a preferred solution, and the angle defined between the two branch portions24may be defined to any value.

In some embodiments, the number of branch portions24is three. The three branch portions24are arranged in a fashion of surrounding the central portion22, and the through holes240of the three branch portions24are respectively passed through by three candle wick bodies140.

It may be understood that according to the actual needs, the number of candle wick structures14and the number of through holes240of the branch portions24are not limited to two or three. For example, the number may be even greater as long as at least one branch portion24is provided with the through hole240. In addition, the through hole240may also be arranged in the central portion22, in the case where the candle wick burning lamp10only includes one candle wick structure14, only one through hole240may be provided in the central portion22, and there is no need to provide a through hole240in the branch portion24.

Hereinafter, description is given by taking a candle wick burning lamp assembly100constituted by a protective device20formed by three branch portions24and a central portion22and a candle wick burning lamp10in cooperation with the protective device20as an example.
