However, this design mainly relies on the physical properties of the evaporation rod itself and the natural flow of air to complete the evaporation and diffusion of the liquid. Due to the lack of active intervention, the evaporation efficiency is often low, especially under conditions of weak airflow or low ambient temperature, where the evaporation effect is significantly limited.

[0049] 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.

[0050] Please see Figures 1-13 As shown, the specific embodiments provided by this utility model are as follows:

[0051] Thermally driven evaporation structures can be widely used in various devices related to liquid evaporation and diffusion to meet the needs of different scenarios.

[0052] For example, this structure can be used for the evaporation and diffusion of insect or mosquito repellent liquids. Through heating and active diffusion, it rapidly improves evaporation efficiency and diffusion range, thereby achieving more efficient insect or mosquito repellent functions. It is suitable for use in homes, outdoor activity areas, farmland, and public areas, providing users with a convenient and reliable solution.

[0053] Furthermore, this structure is also suitable for fragrance devices, such as those used for the evaporation and diffusion of essential oils. Through active thermal diffusion, this structure can rapidly release the aroma molecules of essential oils and evenly diffuse them throughout the room, creating a comfortable and relaxing atmosphere. Whether in a family living room or bedroom, or in commercial spaces such as an office, yoga studio, or hotel, it can effectively meet users' high-quality needs for a pleasant fragrance experience.

[0054] In addition, this structure can be applied to other special scenarios, such as the evaporation and diffusion of liquid medicines or disinfectants, providing support for medical facilities, laboratories, or public health environments. In these scenarios, the thermally driven evaporation structure can achieve stable and efficient liquid evaporation, improving overall application effectiveness and safety.

[0055] refer to Figure 1As shown, the heat-driven evaporation structure includes an evaporation core rod 1. The evaporation core rod 1 has an overall elongated structure, fully considering the requirements for the absorption and flow of the evaporating liquid. One end of the evaporation core rod 1 is an open structure, defined as the first opening 101, and the other end is a closed structure to restrict the liquid from flowing out from that end. Along the axial direction of the evaporation core rod 1, an inner cavity 102 of a predetermined length is formed inside it. This inner cavity 102 extends to the first opening 101 and communicates with the external environment.

[0056] The evaporation mandrel 1 can be inserted into the evaporation container 4 containing the evaporating liquid. Specifically, one end of the closed structure is inserted into the evaporation container 4 and maintains a certain contact with or is completely immersed in the bottom of the container or the liquid surface to ensure that the evaporating liquid can be drawn into the inner cavity 102 of the mandrel. One end of the first opening 101 is usually located outside the evaporation container 4 for the insertion of the heating element of the heat-driven evaporation structure, and accelerates the diffusion of the evaporating liquid under the action of the heated airflow.

[0057] Typically, the evaporation core 1 is inserted vertically into the evaporation container 4. This vertical arrangement not only facilitates the smooth absorption of liquid but also effectively avoids liquid leakage or reduced evaporation efficiency caused by tilting or inversion. The material of the evaporation core 1 is usually a porous material with good capillary action properties and heat resistance to ensure excellent stability and evaporation performance during heating or long-term use.

[0058] Furthermore, the length of the closed end of the evaporation core 1 and the inner cavity 102 can be optimized according to the viscosity, density, and application scenario of different evaporating liquids. For example, in high-viscosity liquids, the length of the inner cavity 102 can be appropriately increased to ensure the continuity of liquid supply; in low-viscosity liquids, the length of the inner cavity 102 can be shortened to improve the evaporation response speed.

[0059] With the above structure, the evaporation core rod 1 can effectively improve the evaporation efficiency by maintaining the stability of liquid supply and through the heating element of the heat-driven evaporation structure, providing a reliable and efficient technical solution for various liquid evaporation equipment.

[0060] The sidewall of the evaporation core rod 1 has one or more second openings. The second openings are non-through structures and are typically concentrated on the sidewall of the evaporation core rod 1 near the first opening 101. Specifically, the second openings are recessed structures, the purpose of which is to increase the effective surface area of ​​the sidewall of the evaporation core rod 1, thereby significantly improving the evaporation area and evaporation efficiency.

[0061] The second opening, through its recessed structure, increases the surface area of ​​the sidewall of the evaporation core rod 1. A larger surface area provides more evaporation contact surface, thereby enhancing the evaporation rate of the liquid.

[0062] The second opening also helps the evaporating liquid to be distributed more evenly on the surface of the evaporating core rod 1, reducing the liquid retention on the surface of the evaporating core rod 1 and ensuring the continuous stability of the evaporation process.

[0063] Furthermore, the number and location of the second opening can be designed and optimized according to specific needs. In some applications, multiple small recesses or a large-scale recess structure can be designed to be adjusted according to different types of volatile liquids, temperature requirements, and evaporation efficiency requirements.

[0064] refer to Figure 1 As shown, the heat-driven evaporation structure includes an electrically heated core rod 2. This heat-driven evaporation structure integrates power connection and heat output functions to meet the requirements of efficient heating and diffusion of volatile liquids.

[0065] Specifically, the structure of the electric heating core rod 2 includes:

[0066] Power supply terminal 201: Used to connect the control circuit and the power supply, ensuring a stable power supply to the electric heating core 2. The power supply terminal 201 is typically made of a material with good electrical conductivity and is designed with a reliable fixed interface for safe connection to external circuits. Furthermore, the control circuit is used to adjust power supply parameters (such as voltage and current) to achieve precise control of the electric heating core 2, thereby adjusting the heating temperature and time as needed.

[0067] Heating end 202: This is the core heating component of the electric heating core rod 2, and its length is typically shorter than the length of the inner cavity 102 of the evaporation core rod 1. It ensures that the heating end 202 can be fully inserted into the inner cavity 102 of the evaporation core rod 1, directly transferring heat to the interior of the evaporation core rod 1, promoting rapid heating and evaporation of the liquid. The heating end 202 is usually made of high-temperature resistant materials, such as metal heating elements, to ensure its long-term stability and high efficiency under high-temperature conditions.

[0068] In operation, power is supplied to the electric heating core rod 2 via the control circuit, causing the heating end 202 to heat up rapidly and transfer heat energy to the inner cavity 102 of the evaporation core rod 1. The inner cavity 102 typically contains a small amount of air and gases from the evaporation of the liquid. During heating, the heat energy causes the gas temperature within the inner cavity 102 to rise rapidly, giving the gas molecules more kinetic energy and significantly enhancing their diffusion capacity. These high-temperature gases continuously diffuse outward along the axial direction of the inner cavity 102, promoting the efficient evaporation and diffusion of the liquid.

[0069] Specifically:

[0070] The inner cavity 102 mainly contains a small amount of air and gas produced by the evaporation and volatilization of volatile liquid. Under heating, the density of this gas mixture decreases and the molecular motion rate increases, thus giving it stronger diffusivity.

[0071] Since the heating end 202 is located directly in the inner cavity 102 of the evaporation core rod 1, the heat transferred from it can quickly raise the overall temperature of the gas inside the inner cavity 102, forming a temperature gradient from the inside of the inner cavity 102 to the outside. The existence of the temperature gradient causes the gas to flow from the inner cavity 102 to the external environment, forming a stable active thermal diffusion process.

[0072] Compared to traditional natural evaporation methods, the thermally driven evaporation of this structure can not only effectively overcome the influence of external factors such as ambient temperature, humidity, and airflow, but also significantly improve evaporation efficiency and diffusion range. Through the synergistic effect of continuous heat supply and the design of the inner cavity 102, the device can achieve rapid evaporation and uniform diffusion of liquids in a short time, meeting the needs of various application scenarios, such as insect repellent, fragrance diffusion, or air purification.

[0073] To accommodate different types of volatile liquids and application scenarios, the control circuit can be designed to support multi-level heating power adjustment to meet the different heating requirements of liquids such as high-boiling-point insect repellents or low-boiling-point fragrances. Furthermore, to ensure safety and extend the device's lifespan, the electric heating core rod 2 typically integrates overheat protection or a temperature feedback module to prevent material damage or safety hazards caused by prolonged high-temperature operation.

[0074] In one specific embodiment, a certain gap is provided between the inner cavity 102 of the electric heating core rod 2 and the evaporation core rod 1, so that the two do not directly contact each other. That is, the inner diameter L1 of the inner cavity 102 of the evaporation core rod 1 is larger than the outer diameter L2 of the electric heating core rod 2.

[0075] The reason is that if the electrically heated core rod 2 is in direct contact with the inner wall of the evaporation core rod 1, a solid-state heat conduction path will be formed. Since the thermal conductivity of solids is much higher than that of gases, this contact may cause heat energy to be rapidly transferred to the overall structure of the evaporation core rod 1, rather than being concentrated on the evaporation process of the gas in the inner cavity 102. This may not only reduce the efficiency of heat utilization, but also raise the external temperature of the evaporation core rod 1, thereby affecting the overall safety and evaporation performance of the device.

[0076] By leaving a certain gap between the electric heating core rod 2 and the inner cavity 102 of the volatile core rod 1, the above problems can be effectively avoided.

[0077] Specifically, by using gas as a heat transfer medium, the heat energy of the heating end 202 is mainly concentrated in the air and the gas after the volatile liquid evaporates in the inner cavity 102, thereby achieving a uniform and efficient heat diffusion effect.

[0078] This prevents heat from being directly conducted to the outer wall of the volatile core rod 1 through the solid, thereby reducing energy waste and ensuring that the outer wall temperature remains within a safe range.

[0079] This avoids overheating of the outer wall caused by solid heat conduction, thereby improving the service life of the device and user safety.

[0080] This non-contact structure allows for more precise control of the heating process while maintaining the stability and efficiency of the device, providing a superior technical solution for liquid evaporation and diffusion.

[0081] Preferably, 0.2mm ≤ L1 - L2 ≤ 3mm. The presence of the gap provides space for thermal convection. Within this range, after the electric heating core 2 is heated, the gas in the gap expands due to heat, forming a natural thermal convection phenomenon. Thermal convection can not only transfer heat more evenly to the inner cavity 102, but also effectively enhance the evaporation rate of the volatile liquid and the diffusion efficiency of the volatile gas.

[0082] refer to Figure 3 and 4 As shown, it includes a sealing body 3. The sealing body 3 is disposed at the power supply end 201 of the electric heating core rod 2 and is used to effectively seal the connection between the electric heating core rod 2 and the evaporation core rod 1. Specifically, when the electric heating core rod 2 is inserted into the inner cavity 102 of the evaporation core rod 1, the sealing body 3 seals the passage of the opening 101 of the evaporation core rod 1 through a sealing contact.

[0083] The sealing body 3 acts as a seal at the power supply end 201 of the electric heating core rod 2, preventing volatile liquid from flowing out through the first opening 101, thereby avoiding liquid leakage or volatile liquid entering the power supply end 201 of the electric heating core rod 2. Through the sealing design, it is ensured that liquid can only evaporate outwards within the inner cavity 102, without affecting the electrical components and circuit safety of the electric heating core rod 2.

[0084] The sealing body 3 can also effectively ensure the reasonable layout of the heat transfer channel between the electric heating core rod 2 and the evaporation core rod 1. Under the sealing effect of the sealing body 3, the inner cavity 102 of the evaporation core rod 1 remains sealed, and the heat energy can be more focused on the gas in the inner cavity 102, avoiding interference from the outside air and ensuring the high efficiency of the heating process.

[0085] The sealing body 3 also provides a certain degree of protection, preventing the electric heating core rod 2 from being affected by foreign objects or causing unnecessary damage when inserted into the evaporation core rod 1. The protective layer provided by the sealing body 3 can extend the service life of the device and improve its stability.

[0086] The material and shape of the sealing body 3 can be adjusted according to the specific application environment to ensure sealing performance while possessing properties such as high temperature resistance and corrosion resistance. For example, the sealing body 3 can be made of silicone or other heat-resistant materials to ensure stable operation for a long time during heating.

[0087] In one specific embodiment, the sealing body 3 has an approximately conical structure. This design allows the sealing body 3 to precisely seal the first opening 101 of the evaporating core rod 1 when the electrically heated core rod 2 is inserted into the inner cavity 102 of the evaporating core rod 1. Specifically, when the electrically heated core rod 2 is inserted into the inner cavity 102 of the evaporating core rod 1, the conical side of the sealing body 3 fits tightly against the inner wall of the first opening 101, forming an effective seal.

[0088] The near-conical side design allows it to fit snugly against the inner wall of the first opening 101 of the evaporation core rod 1, ensuring a highly efficient seal. This structure enables the sealing body 3 to contact the first opening 101 upon insertion, preventing liquid leakage or gas spillage, while also ensuring no heat loss during heating, further improving heat transfer efficiency.

[0089] The conical structure of the sealing body 3 effectively isolates the inner cavity 102 from the power supply end 201 of the electric heating core 2, preventing heat from directly acting on the power supply end 201, thereby maintaining the efficiency and safety of heating. This helps optimize the distribution of heat energy and avoids interference from local overheating and liquid evaporation processes.

[0090] The conical structure of the sealing body 3 also has a guiding function. When the electric heating core rod 2 is inserted into the inner cavity 102 of the evaporation core rod 1, the sealing body 3 can correct the axial displacement of the electric heating core rod 2, ensuring that it maintains a good alignment with the evaporation core rod 1, thus preventing direct contact between the two.

[0091] refer to Figure 2 As shown, the heat-driven evaporation structure includes an evaporation container 4 that matches the outer diameter of the evaporation core rod 1, for holding the evaporating liquid. Specifically, when the evaporation core rod 1 is inserted into the opening of the evaporation container 4, it can seal the opening of the evaporation container 4, ensuring the sealing of the evaporating liquid and the overall sealing of the device.

[0092] Furthermore, the evaporation core rod 1 is designed to cause wetting of the evaporating substance. Wetting ensures that the evaporation core rod 1 can effectively absorb or contact the evaporating liquid, guaranteeing that the evaporating liquid is evenly distributed along the surface of the evaporation core rod 1.

[0093] refer to Figure 2 As shown, a sealing body 401 is provided at the opening of the evaporation container 4. The sealing body 401 has a sealing port at its center for the insertion of the evaporation core rod 1. The sealing port fits tightly with the outer surface of the evaporation core rod 1 to form a sealed connection, thereby ensuring that the liquid inside the evaporation container 4 will not leak, and that the gas and liquid during the evaporation process can be stably evaporated to the outside.

[0094] Specifically, the sealing body 401 can be made of rubber, which has good elasticity and sealing performance. When the evaporation core 1 is inserted into the sealing port, the sealing body 401 can provide a seal between its surface and the evaporation core 1, effectively preventing liquid or gas from leaking from the opening, thereby ensuring the airtightness of the evaporation container 4 and the evaporation core 1. The rubber material has good temperature resistance and chemical corrosion resistance, and can maintain a stable sealing effect during heating, improving the safety and service life of the device.

[0095] refer to Figure 2 As shown, a liquid-absorbing ring 402 is fitted onto the opening of the evaporation container 4. The liquid-absorbing ring 402 is usually made of a material with high liquid absorption performance, such as sponge, fiber material or other substances with strong adsorption, which can effectively absorb the evaporating liquid and keep it stable in the device.

[0096] The suction ring 402 is configured to be movably fitted onto the opening of the evaporation container 4 for easy removal and replacement.

[0097] refer to Figure 5 As shown, the device includes a protective mesh cover 5. The electric heating core 2 is disposed within the protective mesh cover 5. The protective mesh cover 5 is made of high-strength metal or heat-resistant materials, such as stainless steel or ceramic, and possesses good thermal stability and corrosion resistance. Its main function is to protect the electric heating core 2 from external physical interference and damage, and to enhance the safety of the device.

[0098] The protective mesh cover 5 has excellent shielding capabilities, effectively isolating the electric heating core rod 2 from external contact and reducing hazards during operation. Especially during high-temperature operation, the protective mesh cover 5 effectively prevents accidental contact with the electric heating core rod 2, thus avoiding the risk of electric shock and burns and improving operational safety.

[0099] The shape and aperture design of the protective mesh cover 5 should be optimized according to the size and installation position of the electric heating core rod 2 to ensure that it can provide effective protection. In terms of material selection, materials with strong temperature resistance and corrosion resistance should be chosen to ensure long-term stable use under different working conditions.

[0100] refer to Figure 6 As shown, in one specific embodiment, the protective mesh cover 5 includes a evaporation zone 501. The protective mesh cover 5 forms a plurality of mesh openings 5011 in the evaporation zone 501, and at least a portion of the evaporation core rod 1 is located within the evaporation zone 501. Generally, the upper half of the evaporation core rod 1, i.e., the portion not located inside the evaporation container 4, is located within the evaporation zone 501.

[0101] During operation, the volatile liquid adhering to the surface of this part of the volatile core rod 1 is heated and driven, and through the action of thermal energy, the liquid gradually transforms into a gaseous state and diffuses to the outside. The mesh 5011 helps to enhance air circulation, promote the diffusion of volatile gases, and enable the volatile liquid to quickly come into contact with the outside air, thereby improving the evaporation effect.

[0102] In addition, the presence of mesh 5011 can effectively prevent external objects from entering the evaporation area 501, protect the internal components from physical damage, and prevent users from accidentally touching the electric heating core rod 2 or the evaporation core rod 1, ensuring safe use.

[0103] refer to Figure 7 As shown, in one specific embodiment, the protective mesh cover 5 includes a connecting area 502. This connecting area 502 is located below the evaporation area 501 and extends vertically. The purpose of the connecting area 502 is to accommodate the evaporation container 4, ensuring its stable installation in the device and facilitating user operation. Specifically, the evaporation container 4 can be slidably pushed into the space enclosed by the connecting area 502 and can be locked in place after reaching a designated position, preventing displacement or detachment during use.

[0104] In this embodiment, one or more positioning blocks 601 are provided on the bottom sidewall of the evaporation container 4, while positioning grooves 602 are provided in corresponding positions in the connecting area 502. During the installation of the evaporation container 4, the user only needs to slide the evaporation container 4 vertically into the connecting area 502, and the positioning blocks 601 will cooperate and engage with the positioning grooves 602. When the evaporation container 4 slides to a specified depth, the engagement of the positioning blocks 601 and the positioning grooves 602 can effectively prevent the evaporation container 4 from going further, thereby ensuring that the evaporation container 4 is accurately installed in the correct position in the connecting area 502.

[0105] Specifically, the shape and size of the positioning block 601 are precisely matched with the positioning groove 602, allowing the evaporation container 4 to slide in easily and be aligned during installation. When the evaporation container 4 reaches the installation depth, the positioning block 601 is blocked and fixed, preventing the evaporation container 4 from moving due to vibration or external force, and ensuring that its position does not shift. This positioning fit ensures that the evaporation container 4 is always in the optimal working position with the electric heating core rod 2 and the evaporation core rod 1, thereby improving the overall working efficiency of the device.

[0106] The distance between the bottom of the evaporation container 4 and the bottom of the connection area 502 is set between 3mm and 6mm. This distance is set for safety reasons, aiming to prevent children from easily pulling out the evaporation container 4, thus protecting children's safety. With this design, even if a child accidentally operates it, it is not easy for them to directly touch the liquid inside the evaporation container 4, thereby avoiding the risk of accidental contact with the evaporating liquid.

[0107] Specifically, the distance is set between 3mm and 6mm to ensure the stability of the vapor container 4 during installation. Within this range, it is difficult for users (especially children) to easily pull out the vapor container 4 by simple tugging or touching, increasing safety. This design not only optimizes the performance of the device but also provides additional child protection features, effectively reducing safety hazards caused by children's accidental operation and improving the product's family-friendliness and safety.

[0108] refer to Figure 10 As shown, the structural housing includes a first body 701 and a second body 702. When a force is applied to the first body 701 or the second body 702, one of them can slide relative to the other. Specifically, the sliding design between the first body 701 and the second body 702 allows them to move relative to each other under the action of external forces, thereby achieving the gradual concealment and exposure of the evaporation area 501.

[0109] As the two bodies approach each other, the evaporation zone 501 is gradually concealed. At this point, the control circuit should automatically stop supplying power to the electric heating core rod 2 to prevent continued heating while the evaporation zone 501 is concealed. This effectively prevents the heating core rod from consuming electrical energy when it is not in use, ensuring energy efficiency and safety. When the first body 701 and the second body 702 are in complete contact, the evaporation zone 501 is completely concealed inside the structural housing, further improving the safety of the device and preventing the evaporating liquid from being exposed to the outside, reducing external pollution or hazards.

[0110] Conversely, as the first body 701 and the second body 702 move away from each other, the evaporation zone 501 is gradually exposed. Upon detecting this change, the control circuit automatically turns on the power supply to the electric heating core rod 2, restoring the heating function and ensuring the normal operation of the evaporation device, thus initiating the diffusion process of the evaporating liquid. Simultaneously, a lighting lamp can be configured to illuminate the evaporation zone 501 when it is exposed.

[0111] The sliding mechanism of the structural housing enables intelligent shielding and release of the evaporation zone 501, automatically adjusting the working state of the electric heating core 2. This not only improves the ease of use of the device but also adds extra safety protection functions, avoiding unnecessary energy waste and ensuring that the device can efficiently evaporate liquids when needed. Simultaneously, this design effectively prevents users from accidentally coming into contact with the evaporating liquid or heating element, avoiding potential burns or other safety hazards.

[0112] In one embodiment, the power supply and control circuitry are housed within one of the main components, for example, within the first main component 701. This design effectively integrates the power supply and control circuitry, simplifies the overall structure, and maintains the compactness and ease of use of the device.

[0113] refer to Figure 7 As shown, the second main body 702 and the connection area 502 of the protective mesh cover 5 form a sliding sleeve. Specifically, a guide groove 603 is provided in the connection area 502. The function of the guide groove 603 is to guide the second main body 702 to maintain a stable path during sliding, so as to avoid unnecessary deviation or jamming. Correspondingly, a guide block is provided on the inner wall surface of the second main body 702. The guide block cooperates with the guide groove 603 to ensure that the second main body 702 can slide smoothly along the set trajectory.

[0114] To achieve more precise state control, the guide groove 603 is designed as a zigzag path along the axial direction of the protective mesh cover 5. The zigzag path design plays a crucial role: when the guide block slides along the zigzag path, the change in path causes the guide block to be stopped, indicating that the second body 702 and the first body 701 are in a first separation state. In this state, the evaporation zone 501 is fully exposed, allowing the evaporating liquid to enter the working state.

[0115] When the user rotates the second main body 702 by a certain angle, the guide block will move along the changing path of the zigzag path and gradually reach the end point. At this time, the user can continue to pull the second main body 702 circumferentially to completely detach it from the connecting area 502, facilitating further operation or maintenance of the equipment.

[0116] In one specific embodiment, the connection area 502 of the protective mesh cover 5 is also provided with a deformation block 604. The purpose of the deformation block 604 is to ensure that the second body 702 can smoothly transition during relative sliding through a specific deformation mechanism, and accurately connect at the snap-fit ​​position, while avoiding jamming caused by excessive snap-fit ​​force.

[0117] Specifically, the deformation block 604 is disposed in the connecting area 502 and is designed to deform under compressive force during the sliding of the second body 702. When the second body 702 slides along the guide groove 603, the deformation block 604 deforms inward due to external pressure, thereby allowing the second body 702 to continue sliding and passing through the deformation block 604. At this time, the deformation block 604 is temporarily in a deformed state to create space for the subsequent snap-fit ​​process.

[0118] When the second body 702 continues to slide and its internal slot corresponds to the position of the deformable block 604, the deformable block 604 will restore its original shape after the external force is removed and complete the engagement in the slot.

[0119] To ensure a smooth and stable connection process, the deformation block 604 is designed to prevent excessive connection force. This avoids the possibility of complete jamming due to excessive connection force, preventing the deformation block 604 from locking too tightly into the slot and affecting subsequent disassembly or operation.

[0120] The connection area 502 is equipped with an observation slot, while the second main body 702 is equipped with an observation window 7021. The purpose is to allow users to easily understand the remaining amount of evaporating liquid in the evaporation container 4, thereby effectively monitoring the working status of the equipment.

[0121] When the second body 702 is in full contact with the first body 701, the positions of the observation slot and the observation window 7021 will be precisely aligned. At this time, the observation window 7021 is located on the second body 702 and aligned with the observation slot, allowing the user to clearly see the situation inside the observation slot through the observation window 7021. In particular, through this design, at least a portion of the wall surface of the evaporation container 4 is exposed within the observation window 7021 and is visible. In this way, the user can know the remaining amount of evaporating liquid in the evaporation container 4 in real time, avoiding the evaporation device from malfunctioning due to insufficient liquid.

[0122] The observation slot is positioned opposite the wall of the evaporation container 4, and can provide a transparent view to the user through the observation window 7021, ensuring that the user can easily monitor the remaining amount and evaporation status of the liquid during daily use, thereby determining whether the liquid needs to be replenished or maintenance needs to be performed.

[0123] This design not only enhances the user experience but also effectively improves equipment reliability. Users can clearly understand the equipment's operating status and take timely measures to prevent the device from shutting down due to fluid depletion. The combination of the observation tank and observation window 7021 simplifies equipment maintenance and reduces uncertainty and the likelihood of malfunctions during use.

[0124] refer to Figures 10 to 13As shown, a heat-driven evaporation device is provided. The system is designed to combine all the technical features of the above embodiments and focus on optimizing portability to meet the needs of users in outdoor scenarios, such as for mosquito or insect repellent.

[0125] Traditional mosquito or insect repellent devices mostly employ an external heating structure, which heats the evaporating liquid by placing an electric heating element around the outer periphery of the evaporation core 1. However, due to the presence of the external heating element, the device requires an additional insulating element to prevent the user from directly contacting the heated part. The addition of the insulating element not only complicates the device structure but also significantly increases the overall size of the device, hindering portability.

[0126] Isolation components typically require a certain amount of space to ensure safety and heat dissipation. This space further increases the size of the device, making it unsuitable for outdoor use.

[0127] To address the aforementioned issues, this system introduces a heat-driven evaporation structure with a built-in electric heating core rod 2. The electric heating element is designed as an insert structure, directly located within the inner cavity 102 of the evaporation core rod 1, providing a heat source through internal heating. Since the heat source is placed within the inner cavity 102 of the evaporation core rod 1, no additional isolation elements are required, significantly reducing the device size and improving portability. Direct internal heating of the inner cavity 102 of the evaporation core rod 1 results in higher heating efficiency and significantly reduced heat loss. The heat energy drives the rapid diffusion of gases (including air and vapor of the evaporating liquid) within the inner cavity 102, promoting the conversion and diffusion efficiency of the evaporating liquid.
