Description

Technical Field

[0001] This utility model relates to the field of incense products, and in particular to a hollow spiral incense stick with a long burning time. Background Technology

[0002] There are many types of incense available, with different scents and colors, such as stick incense, tribute incense, incense rings, incense cones, mosquito coils, etc. All of them need to be burned. Apart from the differences in scent and color due to customs and personal preferences, the common focus is on how long they burn and the issue of production costs. Because burning long enough and having low production costs are more economical.

[0003] Currently, there are two main types of mosquito coils sold on the market: one is a disc-shaped mosquito coil formed by pressing two mosquito coils together, and the other is a column-shaped incense stick (also called an incense stick). When using a disc-shaped mosquito coil, the adjacent parts of the two coils are broken apart and burned separately. This type of disc-shaped mosquito coil is relatively troublesome to break, often resulting in broken coils, causing inconvenience or waste. Furthermore, when inserting a disc-shaped mosquito coil into another mosquito coil holder, because only the small hole at the center of the coil is inserted into a small, inverted T-shaped holder with a pointed plug, it is easy for it to tip over and extinguish. The existing column-shaped incense sticks are solid columns composed of a bamboo core and a thick, long incense powder (such as wood powder) tightly attached to the bamboo core. When burning these column-shaped incense sticks, the following problems arise: 1. Limited burning time: Because the incense stick has a cylindrical solid structure, considering the center of gravity, safety, and drying time, the diameter of the incense body cannot be too large. Therefore, its burning time is limited, and it cannot be used for extended periods. 2. Low safety: The thick, long incense stick is solid. When burning, the flame covers the entire cross-section of the stick, resulting in an excessively large flame core, high burning temperature, and dense smoke. Carelessness could easily lead to accidents. 3. Difficult to ignite: Because the incense stick tip is solid, it is difficult to ignite and easily extinguishes after ignition. 4. The bamboo skewer core is quite long, increasing production costs. Chinese patent CN200920156873.6 discloses an incense stick that can prolong burning time. It uses a spirally extending groove and one or more long slots parallel to the long axis of the solid column body on its outer diameter surface. The spiral groove provides a longer burning path, while the long slots connected to the groove further cut the burning path, delaying the burning speed and thus extending the burning time. However, its center is still a solid body, and there are still problems such as the diameter of the solid incense body not being too large, the burning time being limited, the flame core of the solid incense stick being too large, the burning temperature being high, the safety being low, and the production cost of long bamboo sticks being high. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems and shortcomings by providing a hollow spiral incense stick that does not require breaking apart for use, reduces unnecessary waste of mosquito coils, has a long burning time, is easy to ignite, is safe to use, and whose hollow structure effectively reduces drying time and the amount of bamboo sticks used, thus greatly reducing production costs.

[0005] The technical solution of this utility model is implemented as follows:

[0006] The hollow spiral incense stick with a long burning time described in this utility model is characterized by comprising a hollow spiral incense stick body extending downward in a spiral shape, a base connected to the lower end of the hollow spiral incense stick body, and an insert rod, the upper end of which extends into the base and the lower end of which extends out of the tail of the base.

[0007] The base can be square or inverted conical. An inverted conical base is preferred.

[0008] Furthermore, the hollow spiral incense stick body is provided with at least two downward-extending supporting connecting ribs, which are used to support and connect the spiral segments. Preferably, four symmetrical ribs are provided. Alternatively, a thin inner connecting cylinder can be provided on the hollow spiral incense stick body, which is used to support and connect the spiral segments. The thickness of the thin inner connecting cylinder is 0.5-2 mm.

[0009] The head of the hollow spiral mosquito coil body is provided with an ignition end, which is a triangular ignition head that is smaller in the front and larger in the back.

[0010] The advantages of this utility model compared with the prior art are:

[0011] First, because the incense stick itself is a hollow spiral structure made directly from incense powder, extending downwards in a spiral shape, with a hollow center and no bamboo core, the outer diameter of the spiral in this application can be made larger than that of existing incense sticks for the same weight. This effectively lengthens the combustion path of the incense powder and prolongs the burning time. Furthermore, the spaces between adjacent spiral segments form ventilation openings, allowing fresh air to flow towards the center during combustion, providing the necessary oxygen for the incense to burn, resulting in better combustion and preventing self-extinguishing. Moreover, because this hollow spiral incense stick has a hollow center and ventilation openings between adjacent spiral segments, its drying time is much shorter than that of existing solid incense sticks, making it easier to dry.

[0012] Second, only a short insert is provided on the base, and the insert does not extend from end to end like existing incense sticks, thus greatly reducing the number of bamboo skewers and effectively lowering production costs. The amount of bamboo skewers used in this application is less than one-eighth of the amount used in existing incense sticks, while the production cost of bamboo skewers in incense stick production is far higher than the production cost of wood powder.

[0013] Third, this utility model also adopts a structure in which at least two supporting connecting ribs or inner connecting thin cylinders extending from top to bottom are provided on the hollow spiral incense stick body, which makes the hollow spiral incense stick body have a good shaping effect and a more reliable structure.

[0014] IV. In the process of use, this utility model can be used immediately by inserting the plug into the ground (such as in the soil), a tabletop, or a ash collection tray. It is extremely convenient to use, and it is not easy to tip over to one side. It has good stability and strong wind resistance.

[0015] Fifth, there is no need to break them apart for separate use, which can reduce unnecessary waste of mosquito coils.

[0016] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0023] like Figures 1-6As shown, the hollow spiral incense stick with long burning time described in this utility model includes a hollow spiral incense stick body 1 extending downward in a spiral shape, a base 2 connected to the lower end of the hollow spiral incense stick body 1, and an insert 3. The upper end of the insert 3 extends into the base 2, and the lower end extends out of the tail of the base 2. The material of the hollow spiral incense stick body can be the incense powder used in existing mosquito coils or incense sticks. Preferably, it is processed from an incense powder mainly composed of natural wood powder (or bamboo powder) with added small-leaf redwood powder and elm powder, and other auxiliary materials (such as emulsifiers, water, etc.; if it is used as a mosquito repellent, insecticides such as tetrafluorobenzyl pyrethroids are added). Small-leaf redwood powder and elm powder contain natural gum, which makes the incense stick body have good adhesion and elasticity, and less prone to breakage. Furthermore, in the processing of this utility model, the hollow spiral incense stick body and the base can be integrally formed, and the insert 3 is inserted and fixed on the base. Alternatively, a hollow spiral incense stick body 1 can be made first from incense powder, then a base and insert can be made, and finally the lower end of the hollow spiral incense stick body 1 can be fixed to the base. The base 2 in this invention can be a square base, a cylindrical base, or an inverted conical base. An inverted conical base is preferred. Figures 1-2 As shown, the hollow spiral incense stick consists of a hollow spiral incense stick body 1 extending downwards in a spiral shape, a base 2 connected to the lower end of the hollow spiral incense stick body 1, and an insert rod 3. To ensure good shaping effect and prevent soft bending deformation and breakage during production and use, the hollow spiral incense stick body 1 is provided with at least two downward-extending supporting connecting ribs 4. These supporting connecting ribs 4 are used to support and connect the spiral segments, strengthening its shaping function. Figure 3 As shown, this is an embodiment with two supporting connecting ribs 4. Figure 4 The illustration shows an embodiment with four supporting connecting ribs 4. This utility model can also be as follows: Figures 5-6 As shown, a thin inner connecting cylinder 5 is provided on the hollow spiral incense stick body 1. The thin inner connecting cylinder 5 is used to support and connect each spiral segment, such as... Figure 2 As shown. The thickness of the thin inner connecting cylinder is 0.5-2 mm. Preferably, it is 1 mm.

[0024] To make it easier to ignite, the head of the hollow spiral mosquito coil body 1 is provided with an ignition end 11, which is a triangular ignition head that is smaller in the front and larger in the back.

[0025] In use, this invention can be directly inserted into the ground, tabletop, or other object via the insertion rod for immediate use. Alternatively, a detachable ash collection tray can be provided at the lower end of the insertion rod, which is then inserted into the ash collection tray for use.
