Abstract
Description
Technical Field
[0001] This utility model relates to the field of aroma sustained release technology, and in particular to an aroma sustained release device for the combustion of incense products. Background Technology
[0002] Incense products are scented items, including traditional incense sticks and coils, primarily used for burning incense and prayer in cultural and ceremonial activities. They also include scented candles and essential oils, used to improve indoor odors, creating a comfortable atmosphere and relieving stress through fragrance. Incense products also include items with added fragrances, such as sachets, which can be worn or placed in wardrobes to repel insects and deodorize. Scent-release technology devices control the rate of fragrance release, allowing the fragrance to be released continuously and stably over a longer period. For example, common reed diffusers use reeds as a medium to slowly release the fragrance from the essential oil into the air. Some rely on natural evaporation, like sachets which release fragrance through the volatility of the ingredients themselves; others use physical methods, such as heated scent-release devices, which use heat to accelerate the evaporation of essential oils, thus regulating the pace of fragrance release.
[0003] A fragrance release device for incense burning is a tool used to control the rate at which incense releases its aroma during combustion. It typically places the incense inside, allowing it to burn continuously and stably, releasing its fragrance. Examples include aromatherapy burners, which provide a safe and stable combustion environment. The device effectively controls the oxygen supply, ensuring the incense burns at an appropriate rate, preventing excessively rapid burning that could result in an overly strong or pungent aroma, or incomplete combustion. Some devices also utilize heat to aid in aroma diffusion, allowing the fragrance to disperse more effectively into the air.
[0004] In existing technologies, some aroma-releasing devices lack effective control mechanisms because most common incense burners and other appliances used for burning incense products lack these mechanisms. Once the incense is lit, it is essentially in a state of natural combustion, allowing air to enter the combustion zone without restriction. This results in an excessively fast combustion rate and a large instantaneous release of aroma, which not only makes it difficult to maintain a uniform and stable aroma concentration for a long time, but also easily causes the indoor aroma to be too strong, causing discomfort and affecting the user experience. Therefore, an aroma-releasing device for burning incense products is proposed to solve the above problems. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a fragrance slow-release device for burning incense products, which aims to improve the problem of excessively fast burning speed and instantaneous release of large amounts of fragrance in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A fragrance slow-release device for burning incense products includes a housing, an interior cavity, a rotating ring rotatably connected to the inner wall of the cavity, an adjusting groove inside the rotating ring, a spring fixedly connected to the bottom of the inner wall of the adjusting groove, a limiting post fixedly connected to the top of the spring, a connecting plate fixedly connected to the front side of the limiting post, multiple limiting grooves inside the housing (top of the rotating ring), a connecting plate (bottom of the connecting plate) fixedly connected to the front side of the rotating ring, a moving block fixedly connected to the front side of the connecting plate, multiple ventilation holes (first type) arranged in a ring inside the housing, multiple ventilation holes (second type) arranged in a ring inside the rotating ring, a sliding groove inside the housing (outer side of the rotating ring), and a maintenance component for disassembling and maintaining the heating module fixedly connected to the bottom of the housing.
[0008] As a further description of the above technical solution:
[0009] The maintenance component includes a protrusion, and a second housing is provided at the bottom of the first housing. Two fixing rings are fixedly connected to the inner wall of the second housing, and the fixing rings have a rotating groove inside.
[0010] As a further description of the above technical solution:
[0011] The outer side of the protrusion is in contact with the inner wall of the rotating groove, and the protrusion slides inside the fixed ring by rotating the housing.
[0012] As a further description of the above technical solution:
[0013] An insulation layer is fixedly connected to the inner wall of the second shell, and a heating block is fixedly connected to the bottom of the inner wall of the second shell;
[0014] As a further description of the above technical solution:
[0015] The outer side of the connecting plate is slidably connected to the inside of the moving block, and the outer side of the limiting post is in contact with the inner wall of the limiting groove.
[0016] As a further description of the above technical solution:
[0017] The rotating ring rotates via the first connecting plate, the second connecting plate, and the moving block, and is limited and fixed by the limiting post, the spring, and the limiting groove.
[0018] As a further description of the above technical solution:
[0019] The rotating ring is released from its fixed position by pressing the connecting plate one and the limiting post, and the ventilation hole two is adjusted in size by rotating the rotating ring;
[0020] As a further description of the above technical solution:
[0021] The top of the housing is provided with a cover plate, and the inside of the cover plate has ventilation holes.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, by rotating the moving block, the connecting plate two and the connecting plate one are driven to move. By pressing the connecting plate one, the limiting post can be moved under the action of the spring and disengaged from or locked into the limiting groove, thereby releasing or fixing the limiting of the rotating ring. The rotating block drives the rotating ring to rotate in the cavity of the housing one. As the rotating ring rotates, the overlapping area of the ventilation hole two and the ventilation hole one changes, thereby making it easy to adjust the size of the ventilation hole, accurately control the burning speed and aroma release of the incense products, and improve the user experience. It can not only change the ventilation condition as needed to adapt to different incense products, but also ensure the stable operation of the device, extend its service life, and enhance the overall practicality.

Detailed Implementation
[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model provides an aroma-releasing device for burning incense products, comprising a housing 1, with a cavity inside the housing 1. The cavity provides a space for the installation and operation of components that adjust the ventilation size. A rotating ring 2 is rotatably connected to the inner wall of the cavity. The rotating ring 2 can rotate freely within the cavity, thereby achieving the switching of different functional states. An adjustment groove 3 is provided inside the rotating ring 2. The adjustment groove 3 provides an installation base for an internal spring 4. The bottom of the inner wall of the adjustment groove 3 is fixedly connected to the spring 4. The spring 4 provides elasticity to the limiting post 5, causing the limiting post 5 to be stuck inside the limiting groove 7. The top of the spring 4 is fixedly connected to the limiting post 5. The limiting post 5 can move up and down within the adjustment groove 3 under the action of the spring 4.
[0034] A connecting plate 6 is fixedly connected to the front side of the limiting post 5. The connecting plate 6 serves to connect and transmit force. Multiple limiting grooves 7 are opened inside the housing 1, i.e., the top of the rotating ring 2. These limiting grooves 7 are evenly distributed, and their depth and shape match the limiting post 5. They are used to limit and fix the rotating ring 2 at a specific position. A connecting plate 8 is fixedly connected to the bottom of the connecting plate 6, i.e., the front side of the rotating ring 2. The connecting plate 8 further enhances the stability and conductivity of the connection structure.
[0035] A movable block 9 is fixedly connected to the front side of the connecting plate 2 8. The movable block 9 allows the user to manually operate the rotation of the rotating ring 2. Multiple ventilation holes 10 are arranged in a ring inside the housing 1. The ventilation holes 10 provide adequate airflow and sufficient oxygen when the incense product is burning. Multiple ventilation holes 2 11 are arranged in a ring inside the rotating ring 2. The ventilation holes 2 11 are divided into three sizes: large, medium, and small. They are evenly distributed in a ring inside the rotating ring 2. A sliding groove 12 is provided inside the housing 1, which is the outside of the rotating ring 2. The sliding groove 12 provides guidance and limit for the sliding of the movable block 9. A maintenance component for disassembling and maintaining the heating module is fixedly connected to the bottom of the housing 1.
[0036] Reference Figure 3 and Figure 4 The maintenance component includes a protrusion 13, which serves as a key connection and positioning component. A second housing 14 is located at the bottom of the housing 1. The second housing 14 and the first housing 1 cooperate with each other in the overall device structure to form a complete space for containment and protection. Two fixing rings 15 are fixedly connected to the inner wall of the second housing 14. The fixing rings 15 are symmetrically or in a specific layout on the inner wall of the second housing 14. The fixing rings 15 have a rotating groove 16 inside, which allows the protrusion 13 to rotate precisely and freely within the rotating groove 16, thereby providing the necessary mechanical motion basis and structural support for the disassembly and maintenance of the heating module.
[0037] Reference Figures 2 to 4 The outer surface of the protrusion 13 contacts the inner wall of the rotating groove 16, ensuring stable force transmission and precise guidance during rotation. The protrusion 13 slides inside the fixed ring 15 through the rotating housing 14. When the user manually applies a certain torque to the housing 14, the protrusion 13 will slide smoothly along a predetermined trajectory in the rotating groove 16. This sliding motion drives other connected components to perform coordinated actions, providing the necessary motion conditions for the disassembly or installation of the heating module. The inner wall of the housing 14 is fixedly connected to the heat insulation layer 17, which can effectively prevent heat from being lost from the inside of the housing 14 to the outside. The bottom of the inner wall of the housing 14 is fixedly connected to the heating block 18, which serves as the core component for providing heat.
[0038] The external sliding connection of the connecting plate 6 is inside the moving block 9, ensuring that the connecting plate 6 can slide smoothly inside the moving block 9, and preventing shaking or displacement due to excessive gap. This allows the force to be stably transmitted to the rotating ring 2 through the connecting plate 6 when the moving block 9 is operated to drive the rotating ring 2, achieving precise angle control and position adjustment. This provides a reliable mechanical transmission guarantee for adjusting the size of the ventilation opening between the ventilation hole 11 and the ventilation hole 10. The external of the limiting post 5 is in contact with the inner wall of the limiting groove 7. Under the elastic force of the spring 4, the limiting post 5 always maintains the contact pressure with the inner wall of the limiting groove 7. Even when the device is subjected to certain vibrations or external impacts, it can effectively prevent the rotating ring 2 from rotating accidentally and maintain the established working state of the device. The rotating ring 2 rotates through the connecting plate 6, the connecting plate 8, and the moving block 9. When the user operates the moving block 9, the movement of the moving block 9 is transmitted to the connecting plate 6 through the connecting plate 8, thereby driving the rotating ring 2 to rotate smoothly in the cavity of the housing 1.
[0039] The rotating ring 2 is limited and fixed by the limiting post 5, the spring 4, and the limiting groove 7. The elasticity of the spring 4 pushes the limiting post 5 back into the limiting groove 7, thus achieving the limiting and fixing. The rotating ring 2 is released from the limiting and fixing state by pressing the connecting plate 6 and the limiting post 5. After the operation is completed, simply release the pressing force, and the spring 4 will automatically reset the limiting post 5 into the limiting groove 7, restoring the rotating ring 2 to the limiting and fixed state.
[0040] The size of the ventilation opening 11 is adjusted by rotating the rotating ring 2. When the rotating ring 2 rotates to a specific position, the ventilation opening 11 and the ventilation opening 10 completely overlap. At this time, the ventilation opening reaches its maximum opening, and a large amount of air can enter the device, promoting the rapid combustion of the incense and the rapid release of the aroma. When the rotating ring 2 rotates in the opposite direction, the overlapping area of the ventilation opening 11 and the ventilation opening 10 gradually decreases, the ventilation opening becomes smaller, the amount of air entering the device decreases, and the combustion speed and aroma release speed of the incense also decrease. By controlling the rotation angle of the rotating ring 2, the size of the ventilation opening can be finely adjusted, thereby meeting the requirements of different incense products and usage scenarios for aroma release concentration and speed.
[0041] The top of the casing 1 is provided with a cover plate 19. The cover plate 19 prevents dust, debris and other objects from entering the device and also serves a certain decorative and protective function. The cover plate 19 has ventilation holes 20 inside. The presence of ventilation holes 20 allows the aroma produced by combustion or volatilization inside the device to be smoothly dispersed into the external environment. At the same time, it can also balance the air pressure inside and outside the device to a certain extent, ensuring normal air circulation and ensuring that the incense products can continuously and stably burn or volatilize and release aroma.
[0042] Working principle: When adjusting the size of the vent, rotating the moving block 9 moves the connecting plate 2 8 and the connecting plate 1 6. Pressing the connecting plate 1 6 moves the limiting post 5 under the action of the spring 4, causing it to disengage from or engage with the limiting groove 7, thereby releasing or fixing the limiting position of the rotating ring 2. After the rotating ring 2 is released from its limiting position, rotating the moving block 9 causes the rotating ring 2 to rotate within the cavity of the housing 1. As the rotating ring 2 rotates, the overlapping area of the ventilation hole 2 11 and the ventilation hole 10 changes. By controlling the rotation angle of the rotating ring 2, the size of the vent can be finely adjusted to meet the requirements of different fragrance products and usage scenarios for fragrance release concentration and speed.
[0043] When the heating module needs to be disassembled for maintenance, the housing 14 is rotated, which drives the fixing ring 15 to rotate. This causes the fixing ring 15 and the rotating groove 16 to rotate, disengaging the protrusion 13 from the rotating groove 16. The contact between the protrusion 13 and the rotating groove 16 ensures stable force transmission and precise guidance during rotation, enabling the entire operation to be carried out accurately and smoothly. This allows for convenient maintenance of the heating module, ensuring the normal operation and stable performance of the entire device. The cover plate 19 on the top of the housing 1 prevents dust and debris from entering, and its vent 20 ensures aroma dissipation and air circulation, maintaining the internal air pressure balance of the device. This ensures that the incense products can continuously and stably burn or release aroma. All components of the entire device work together to effectively realize the aroma slow-release technology function.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
