Description

Technical Field

[0001] This utility model relates to the field of volatile fuel core rods, and more particularly to a wood fiber combustion fuel core rod. Background Technology

[0002] Due to their stable ability to wet and evaporate pesticides, volatile oil cores are widely used in mosquito repellents, aromatherapy products, and other similar applications. Currently, commonly used materials for volatile oil cores include nylon, cotton, polypropylene, and polyester. The filaments of these materials are compressed into strands and then cut to form the volatile oil core, allowing it to absorb the pesticide and release it through its internal pores.

[0003] In publicly available documents, patent application number 202022655007.0 discloses a fiber evaporator core for preventing drug leakage. The core includes a fiber evaporator body and a seepage-proof wrapping layer. The seepage-proof wrapping layer circumferentially wraps around the outer wall of the fiber evaporator body, completely sealing the pores on the outer wall and forming a drug flow channel extending axially within the fiber evaporator body. The seepage-proof wrapping layer and the fiber evaporator body are an integral structure. This invention effectively prevents drug leakage by completely sealing the pores on the outer wall of the fiber evaporator through the seepage-proof wrapping layer.

[0004] However, the existing fiber evaporation core's impermeable wrapping layer has a low ignition point, making it easily ignited during the evaporation process. This leads to damage to the core structure, causing the liquid to leak out during combustion and preventing complete evaporation. Therefore, it is necessary to improve this structure to overcome these shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a wood fiber combustion core rod to solve the problem that the existing fiber volatilization core has a low ignition point of the anti-seepage wrapping layer, which is easily ignited during the volatilization process, resulting in damage to the core structure and leakage of the liquid during combustion, preventing complete volatilization.

[0006] The above-mentioned technical objective of this utility model is achieved by the following technical solution:

[0007] A wood fiber combustion core rod includes a core rod body with a plurality of liquid channels formed thereon. The first end of each liquid channel is located on the outer wall of the core rod body, and the second end of each liquid channel extends inward into the core rod body. A through hole is formed on the core rod body, extending axially along the core rod body and penetrating both ends of the core rod body. The core rod body also includes…

[0008] The combustion layer is attached to the inner wall of the through hole and extends along the axial direction of the through hole. The combustion layer seals the liquid channel on the inner wall of the core rod body.

[0009] A sealing layer is fitted onto the core rod body, with one side of the sealing layer adhering to the outer wall of the core rod body. The sealing layer seals the liquid channel on the outer wall of the core rod body.

[0010] A connecting layer is provided on one end of the mandrel body. The connecting layer is attached to the mandrel body, the outer end of the connecting layer is connected to the sealing layer, and the inner end of the connecting layer is connected to the combustion layer. The connecting layer seals the liquid channel on the end of the mandrel body.

[0011] The ignition point of the combustion layer is lower than that of the sealing layer and the connecting layer.

[0012] A further feature of this invention is that the core rod body is a component made of wood fiber pressed together.

[0013] A further feature of this invention is that the combustion layer is a component made of pressed cotton fibers.

[0014] A further feature of this invention is that the combustion layer and the inner wall of the core rod body are integrally formed.

[0015] A further feature of this invention is that the sealing layer and the outer wall of the mandrel body are integrally formed.

[0016] A further feature of this invention is that the connecting layer and the end of the mandrel body are integrally formed.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. Highly efficient insect repellent and insect control: The high temperature generated by the combustion of the combustion layer causes the pesticide in the liquid channel to volatilize and diffuse, thereby effectively repelling and killing insects. The ignition point of the combustion layer is lower than that of the core rod body, sealing layer, and connecting layer. The difference in ignition point ensures that the combustion layer can burn when it reaches the predetermined temperature, while the core rod body, sealing layer, and connecting layer can maintain structural integrity and functional stability.

[0019] 2. Stable structure: The core rod body is made of wood fiber, which has a relatively light weight and a certain strength. At the same time, the combustion layer, sealing layer and connecting layer are integrally molded with the core rod body, which enhances the overall structural stability.

[0020] 3. Strong sealing performance: The sealing layer seals the liquid channel on the outer wall of the core rod body, providing a liquid sealing guarantee and preventing liquid leakage. At the same time, the connecting layer also ensures a tight connection between the sealing layer and the combustion layer. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with the illustrations and specific embodiments.

[0026] like Figures 1 to 3 As shown, this utility model proposes a wood fiber combustion core rod, including a core rod body 1. The core rod body 1 is a cylindrical solid structure. Several liquid channels extending inward are formed on the core rod body 1 from any part of its outer wall (the starting section can be at the end or on the side wall). It should be noted that because the liquid channels can be randomly formed inside the core rod body, the attached... Figure 1 and 2 The medicine channel 2 is shown in the form of a filler. In fact, there are multiple medicine channels inside the filler. The solid between adjacent medicine channels is the core rod body 1.

[0027] Combination Figure 1 and Figure 2 The first end of the liquid channel 2 is located on the outer wall of the core rod body 1, and the second end of the liquid channel 2 extends into the core rod body 1. It can penetrate the core rod body or not (in the shape of a blind hole). The liquid channel 2 is used as a carrier to store the liquid. The liquid can flow into the interior of the core rod body 1 along the channel. The core rod body 1 is provided with a through hole 3. The through hole extends along the axial direction of the core rod body 1 and penetrates both ends of the core rod body 1. The through hole 3 is used to provide the combustion layer 4 with the space and oxygen required for combustion. When in use, the fire source is put into the through hole 3 to ignite the combustion layer 4, so that the core rod body 1 burns from the inside out.

[0028] See Figure 2 The combustion layer 4 is attached to the inner wall of the through hole 3 and extends along the axial direction of the through hole 3. When the liquid medicine needs to be released, the combustion layer 4 is heated by external heating to reach the ignition point and burn. The high temperature generated during the combustion process causes the medicine in the liquid medicine channel 2 to volatilize and diffuse, which plays the role of repelling and killing insects. The material used in the combustion layer 4 has a low ignition point. When it comes into contact with a fire source, it will be quickly ignited and the heat will be transferred to the core rod body 1 to ensure the evaporation rate of the liquid medicine.

[0029] See also Figure 2The sealing layer 5 is fitted onto the core rod body 1. One side of the sealing layer 5 is attached to the outer wall of the core rod body 1. The sealing layer 5 seals the liquid channel 2 on the outer wall of the core rod body 1, providing a liquid sealing guarantee and preventing liquid leakage.

[0030] See Figure 3 The connecting layer 6 is disposed on one end of the core rod body 1. The connecting layer 6 is attached to the core rod body 1 and is in the shape of a ring. The outer end of the connecting layer 6 is connected to the sealing layer 5, and the inner end of the connecting layer 6 is connected to the combustion layer 4. The connecting layer 6 seals the liquid channel 2 on the end of the core rod body 1. The connecting layer 6 enables the sealing layer 5 and the combustion layer 4 to be tightly connected together to form a continuous sealing surface to prevent liquid leakage.

[0031] The ignition point of the combustion layer 4 is lower than that of the sealing layer 5 and the connecting layer 6. The difference in ignition points ensures that the combustion layer 4 can burn when it reaches the predetermined temperature, while the sealing layer 5 and the connecting layer 6 can maintain structural integrity and functional stability.

[0032] In this embodiment, the core rod body 1 is a component made of wood fiber pressing. The core rod body 1 made of wood fiber pressing has a relatively light weight and some strength.

[0033] In this embodiment, the combustion layer 4 is a component made of pressed cotton fibers. Cotton fibers have a relatively low ignition point and are easy to ignite. This allows the combustion layer 4 to quickly reach its ignition point and burn when needed, and ignite the core rod body 1, causing the liquid medicine to evaporate.

[0034] In this embodiment, the combustion layer 4 is integrally formed with the inner wall of the core rod body 1, the sealing layer 5 is integrally formed with the outer wall of the core rod body 1, and the connecting layer 6 is integrally formed with the end of the core rod body 1. The integrally formed structure ensures that there are no gaps between each layer and the core rod body 1, thereby enhancing the overall structural stability and reducing the risk of liquid leakage due to loose or failed connectors. The integrally formed sealing layer 5 can more effectively fit the outer wall of the core rod body 1 to form a tight sealing barrier. The integrally formed combustion layer 4 and connecting layer 6 can also ensure the complete sealing of the liquid channel 2, preventing liquid leakage when not needed.

[0035] The usage process and principle of this utility model are as follows: The wood fiber combustion core is placed in the area requiring insect repellency and control. An external heat source is introduced into the through-hole 3, igniting the combustion layer 4, causing it to quickly reach its ignition point and burn. The high temperature generated by the combustion of the combustion layer 4 causes the pesticide in the liquid channel 2 to evaporate and diffuse into the surrounding environment, thus repelling and controlling insects. After continuous combustion, the core body 1 is also ignited, causing the pesticide to completely evaporate. Because the liquid channel 2 is tightly sealed by the combustion layer 4, the sealing layer 5, and the connecting layer 6, the pesticide will not leak when not needed. When the combustion layer 4 has burned out, the use of the wood fiber combustion core ends, but the pesticide has fully evaporated and achieved its insect repellency and control effect. In summary, the wood fiber combustion core has advantages such as high efficiency in insect repellency and control, stable structure, strong sealing, and easy ignition, making it suitable for various occasions requiring insect repellency and control. Furthermore, its usage is simple and convenient, and its operating principle is clear and straightforward, ensuring safety and effectiveness.
